Item 2.  Acquisition or Disposition of Assets.

     On July 2, 1999, ACE Limited (the "Company"), through its wholly owned
subsidiary ACE INA Holdings, Inc. ("Holdings"), completed the acquisition of the
domestic and international property and casualty business (the "Acquired
Business") of CIGNA Corporation ("CIGNA") for the previously announced price of
$3.45 billion in cash. The transaction is initially being financed with $1.025
billion of available cash, $400 million from a hybrid trust preferred security
and the remainder with commercial paper issuance. Ultimately, the commercial
paper will be replaced with a combination of newly issued equity, senior debt
and trust preferred securities. A copy of the Acquisition Agreement and
Amendments Nos. 1 and 2 thereto are filed as Exhibits 2.1, 2.2 and 2.3 to this
Form 8-K.

     Also put in place at the closing was the previously announced reinsurance
arrangement with National Indemnity Company (a subsidiary of Berkshire Hathaway)
providing $1.25 billion in protection against adverse development in the run-
off operations and certain asbestos and environmental exposures of ACE INA.

     The Company has also entered into a 10-year agreement with IBM Global
Services ("IBM") to manage the transition and integration of the information
technology ("IT") infrastructure for the Acquired Business and to provide
ongoing IT support for these operations. The outsourcing agreement will transfer
approximately 350 employees to IBM together with the software, hardware and
other facilities necessary to provide these services.  A copy of the agreement
with IBM is filed as Exhibit 99.1.

     Included as Exhibit 99.2 to this Current Report on Form 8-K is a copy of
the press release dated July 2, 1999 announcing such completion.

Item 5.    Other Events

     In connection with the completion of the acquisition of the Acquired
Business, ACE RHINOS Trust, a Delaware statutory business trust (the "Trust"),
sold in a private placement $400 million of Auction Rate Reset Preferred
Securities (the "Preferred Securities").  All of the common securities of the
Trust are owned by Holdings.

     The Preferred Securities mature on September 30, 2002.  Distribution on the
Preferred Securities are payable quarterly at LIBOR plus 125 basis points,
adjusted quarterly, provided that the Trust may defer such payments (but no
later than September 30, 2001 or earlier Redemption Date), with such deferred
payments compounded quarterly, if Holdings defers interest on the Subordinated
Notes (as defined below).  If the trading price of ACE's Ordinary Shares
declines to 66-2/3% of the closing price of ACE's ordinary shares on June 30,
1999, the holders of a majority of the Preferred Securities will have the
option to require Banc of America Securities LLC ("BAS") as the Remarketing
Agent to remarket the Preferred Securities. If remarketed, the maturity of the
remarketed securities will be reset as the later of September 30,

                                      -2-
<PAGE>

2001 or one year from the date on which the remarketed securities are issued.
The coupon will be reset pursuant to a bid process to value the remarketed
securities at 100.25% of the face amount thereof. A copy of the Remarketing and
Contingent Purchase Agreement is filed as Exhibit 99.3 to this Form 8-K.

     The sole assets of the Trust consist of a $412,372,000 Auction Rate Reset
Subordinated Notes Series A (the "Subordinated Notes") issued by Holdings. The
Subordinated Notes mature on September 30, 2001. Interest on the Subordinated
Notes is payable quarterly at LIBOR plus 125 basis points, adjusted quarterly,
provided that Holdings may defer such interest payments (but no later than the
September 30, 2001 or earlier Redemption Date), with such deferred payments
compounded quarterly. If under certain circumstances the Trust is dissolved and
the holders of the Preferred Securities directly holds the Subordinated Notes,
then the remarketing provisions described above will be applicable to the
Subordinated Notes. A copy of the Indenture and Supplemental Indenture is filed
as Exhibits 99.5 and 99.6 to this Form 8-K.

     In connection with the issuance of the Preferred Securities, the Company
has agreed with BAS to use its reasonable best efforts to complete one or more
firm commitment underwritings with an aggregate public offering price of $400
million on or before June 30, 2002.  The Company has agreed to maintain an
effective shelf registration statement with availability for the issuance of up
to $400 million ordinary shares (exclusive of any amounts to cover over-
allotments).  A copy of the letter agreement is filed as Exhibit 99.4 to this
Form 8-K.

Item 8.  Change in Fiscal Year

     Effective July 2, 1999, the Company changed its fiscal year so that its
fiscal year will now commence on January 1 and end on December 31.  This change
was made to align the Company's fiscal year end with the statutory year ends of
the majority of its subsidiaries.  A Quarterly Report on Form 10-Q for the
transition period from September 30, 1998 through December 31, 1998 will be
filed.

     Because of the change in fiscal year, the 2000 annual general meeting of
stockholders will be held on June 9, 2000. Accordingly, the deadline for
stockholders who wish to submit a proposal to be considered for inclusion in the
proxy statement for such annual meeting has been extended. Stockholders wishing
to submit such a proposal should send it to the Secretary, ACE Limited, The ACE
Building, 30 Woodbourne Avenue, Hamilton HM 08 Bermuda so that it is received no
later than December 31, 1999 and such proposal must otherwise comply with the
requirements of the U.S. Securities and Exchange Commission to be eligible for
inclusion in the Company's 2000 annual general meeting proxy statement and form
of proxy. Under the Company's Articles of Association, the deadline for advance
notice to submit a proposal for consideration at the 2000 annual meeting, or to
nominate persons for election as directors, did not change. Such written  notice
must be received by the Secretary of the Company on or prior to December 7,
1999. The notice must meet the requirements set forth in the Company's Articles
of Association. Under the circumstances described in, and upon compliance with,
Rule 14a-4(c) under the Exchange Act, management proxies would be allowed to use
their discretionary voting authority to vote on any proposal with respect to
which the foregoing requirements have been met.

Closing have not been fulfilled or waived (such Deferrable Acquired
International Companies and such Equity Insurance Joint Venture Agreements that
were not conveyed to the Purchaser as part of the Closing and, as may be
determined from time to time, have not as of any such subsequent time been
conveyed to the Purchaser as part of any consummated Subsequent Closing, the
"Deferred Companies" and the "Deferred Joint Venture Agreements," respectively,
and, together, the "Deferred Assets"), and that one or more subsequent closings
("Subsequent Closings") in respect of the Deferred Assets will take place
following the Closing. Each Subsequent Closing will take place at 10:00 a.m.,
New York City time, on a date (each, a "Subsequent Closing Date") to be agreed

the parties shall deliver or cause to be delivered to the intended recipient any
moneys, documents and instruments required to be delivered by or on behalf of
such party at or prior to such closing pursuant to the terms of this Agreement.

               (4)  In the event that all of the conditions to Closing in
respect of all of the Acquired Assets have not been fulfilled or waived or all
of the conditions to a Subsequent Closing in respect of all of the then-existing
Deferred Assets have not been

                                       4
<PAGE>

fulfilled or waived, then the parties hereto shall agree upon the appropriate
actions which such parties and their affiliates shall take in order to ensure
that the Deferred Assets not included as part of the Closing or such Subsequent
Closing, as the case may be, are not inadvertently conveyed to the Purchaser at
such time.

                       -------------------------

               (1)  In the event that all of the conditions to Closing set forth
in Section 7.1 hereof in respect of all of the Acquired Assets are fulfilled or
waived as of the Closing, then, at the Closing, the Purchaser shall deliver to
CIGNA Holdings the Purchase Price by wire transfer of immediately available
funds to an account designated in writing by CIGNA Holdings no less than five
business days prior to the Closing.

               (2)  In the event that all of the conditions to Closing set forth
in Section 7.1 hereof in respect of one or more of the Deferrable Acquired
International Companies or Equity Insurance Joint Venture Agreements have not
been fulfilled or waived as of the Closing, then:

                    (1)   at the Closing, the Purchaser shall deliver
     to CIGNA Holdings an amount equal to the difference determined by
     subtracting the aggregate amount of the local statutory surplus
     determined as of the most recent date for which such information
     is available for each of the Deferred Assets

                                       5

     portion of the Deferred Purchase Price Payment Amount which is
     attributable (using the methodology set forth in Section
     1.4(b)(i)(1) above) to the Deferred Assets in respect of which
     such Subsequent Closing is being held, by wire transfer of
     immediately available funds to an account designated in writing
     by CIGNA Holdings no less than five business days prior to such
     Subsequent Closing.

          Section 1.5  Assumption of Liabilities.  At the Closing (and
                       -------------------------
regardless of whether or not any Subsequent Closings are then contemplated and
whether or not any Deferred Assets exist following the Closing), the Purchaser
shall assume all liabilities and obligations of any kind or nature whatsoever,
whether fixed, absolute, matured, unmatured, accrued, contingent, known or
unknown, set forth on Section 1.5 of the Seller Disclosure Schedule
(collectively, the "Assumed Liabilities").  At the Closing, the Sellers and
their affiliates (as defined in Section 10.1) and the Purchaser shall execute
and deliver the Assignment and Assumption Agreement, reinsurance agreements and
such other documents and instruments as may be necessary in order to effect the
Purchaser's assumption of the Assumed Liabilities.

whether or not incorporated (an "ERISA Affiliate"), that together with CIGNA or
any of its subsidiaries would be deemed a "single employer" within the meaning
of Section 4001(b) of ERISA, or to which CIGNA or any of its subsidiaries or an
ERISA Affiliate is party, for the benefit of any employee or former employee of
the Business (the "Plans") other than any Plan that is not subject to United
States Law (any such Plan, a "Foreign Plan"). Section 2.9(a) of the Seller
Disclosure Schedule also contains a true, correct and complete list, as of the

                                       17

subject to Section 302 or Title IV of ERISA or Section 412 of the Internal
Revenue Code of 1986, as amended (the "Code"), is hereinafter referred to in
this Agreement as a "Title IV Plan".

               (2)  With respect to each Plan other than any Foreign Plan, CIGNA
has heretofore made available to the Purchaser true, correct and complete copies
of each of the following documents, to the extent applicable: a copy of each
Plan (or, in the case of an unwritten Plan, a summary of the material terms
thereof) and any amendments thereto; and a copy of the most recent Summary Plan
Description required under ERISA. With respect to each material Foreign Plan,
CIGNA has heretofore used its Reasonable Best Efforts to make available to the
Purchaser true, correct and complete copies of plan documents, descriptions and
summaries relating thereto.

               (3)  No liability under Section 302 or Title IV of ERISA has been
incurred by CIGNA or its subsidiaries or any ERISA Affiliate that has not been
satisfied in full, and, to the knowledge of the Sellers, no condition exists
that presents a material risk to CIGNA or its subsidiaries or any ERISA
Affiliate of incurring any such liability. Insofar as the representation made in
this Section 2.9(c) applies to Sections 4064, 4069 or 4204 of Title IV of ERISA,
it is made with respect to any employee benefit plan, program, agreement or
arrangement subject to Title IV of ERISA to which CIGNA or any of its
subsidiaries or any ERISA Affiliate made, or was required to make, contributions
during the five-year period ending on the last day of the most recent plan year
which ended prior to the Closing Date.

               (4)  The Pension Benefit Guarantee Corporation has not instituted
proceedings to terminate any Title IV Plan.

               (5)  No Title IV Plan or any trust established thereunder has
incurred any "accumulated funding deficiency" (as defined in Section 302 of
ERISA and Section 412 of the Code), whether or not waived, as of the last day of
the most recent fiscal year of each Title IV Plan which ended prior to the
Closing Date. All contributions required to be made with respect to any Plan on
or prior to the Closing Date have been made in full.

               (6)  No Title IV Plan is a "multiemployer pension plan," as
defined in Section 3(37) of ERISA.

               (7)  Each Plan has been operated and administered in all material
respects in accordance with its terms and in accordance with Law, including but
not limited to ERISA and the Code and no written notice has been delivered to
CIGNA by any governmental authority questioning or challenging such compliance.
Each Plan intended to be "qualified" within the meaning of Section 401(a) of the
Code has received a determination letter from the Internal Revenue Service
stating that it is so qualified and, to the knowledge of the Sellers, no event
has occurred since the date of such letter which could reasonably be expected to
give rise to disqualification of any such Plan. There are no pending, threatened
or anticipated claims by or on behalf of any Plan, by any participant or
beneficiary covered under any such Plan, or otherwise involving any such Plan
(other than routine claims for benefits).

anything to the contrary contained in Section 4.1(a) hereof, if the transactions
to be implemented pursuant to Article I of the Excluded Business Transfer
Agreement would result in an adverse effect on all or a portion of the Business,
then the Sellers must obtain the written consent of the

Purchaser (not to be unreasonably withheld) before implementing any such

                        -----------

                  (1)   From the date of this Agreement through the Closing (and
regardless of whether any Subsequent Closings occur), none of CIGNA or its
subsidiaries, or their respective officers, employees, representatives or agents
will, directly or indirectly, solicit, encourage or initiate any negotiations or
discussions with, or provide any information to, or otherwise cooperate in any
manner with, any person or group of persons (other than the Purchaser and its
affiliates) concerning any direct or indirect sale or other disposition of all
or a material portion of the Business.

                  (2)   From the date of this Agreement through the Closing, the
Purchaser will not take, nor agree to commit to take, any action that could
reasonably be expected to impede the ability of the Purchaser to consummate the

                        ------------------------------------------------------

                  (1)   Prior to the Closing Date, the Purchaser shall be
entitled, through its employees and representatives, to make such further
investigation of the assets, liabilities, business and operations of the
Business, and such further examination of the Books and Records, as the
Purchaser may reasonably request. Any investigation, examination or interview by
the Purchaser of employees of CIGNA or any of its subsidiaries or access
pursuant to any of the provisions of this Section 4.3(a) shall be conducted or
occur at reasonable times during regular business hours upon reasonable prior
notice. Each of the parties hereto and its employees and representatives,
including, without limitation, counsel, environmental consultants, investment
bankers

                                       51
<PAGE>

and independent public accountants, shall cooperate with the other's employees
and representatives, as the case may be, in connection with such review and
examination. Any such investigation, examination or interview shall be subject
to the terms and conditions of the letter agreement, dated September 14, 1998,
between the Purchaser and CIGNA (as may be amended, the "Seller Confidentiality
Agreement") and shall be subject to all other legal limitations (including
attorney-client and work product privileges, confidentiality, antitrust and fair
trade limitations). Each of the parties hereto shall cooperate in implementing
the provisions of this Section 4.3 so as to not unreasonably interfere with
CIGNA's or any of its subsidiaries' (or any of their successors') business
operations.

             (2)   Prior to the Closing Date, the Sellers shall be entitled,
through their employees and representatives, to make such further investigation
of the assets, liabilities, business and operations of the Purchaser and its
subsidiaries, as the Sellers may reasonably request, in connection with the
Financing Commitment Letter and the ability of the Purchaser to finance the
transactions contemplated hereby. Any investigation, examination or interview by
the Sellers of employees of the Purchaser or any of its subsidiaries or access
pursuant to any of the provisions of this Section 4.3(b) shall be conducted or
occur at reasonable times during regular business hours upon reasonable prior
notice. Each of the parties hereto and its employees and representatives,
including, without limitation, counsel, investment bankers and independent
public accountants, shall cooperate with the other's employees and
representatives, as the case may be, in connection with such review and
examination. Any such investigation, examination or interview shall be subject
to the terms and conditions of the Purchaser Confidentiality Agreement and shall
be subject to all other legal limitations (including attorney-client and work
product privileges, confidentiality, antitrust and fair trade limitations).

<PAGE>

               (3)  In addition, prior to the Closing Date, CIGNA and the
Purchaser shall, and shall cause their respective subsidiaries to, in respect of
the Business, cooperate with respect to transition matters, including to: (i)
provide access to their employees in respect of transition planning; (ii)
designate certain of their employees to serve as members of a joint
CIGNA/Purchaser transition team and cause such individuals to devote reasonable
time to transition matters (it being agreed that neither CIGNA (including its
subsidiaries), on the one hand, nor the Purchaser (including its subsidiaries),
on the other, is required to appoint more than 20 employees to such team); (iii)
devote office accommodations and related facilities for a continuing presence of
transition team members on the premises of CIGNA; (iv) promptly provide the
other parties hereto with copies of all correspondence or written communication
among any party hereto or any of the Acquired Companies, on the one hand, and
A.M. Best Company Inc., Standard & Poor's or Moody's Investors Service, Inc., on
the other, which relates to the business of such entity and which is material to
the financial condition or operation of such entity; (v) consult with the other
regarding their development work pertaining to systems, products, distribution
and customer and producer services relating to the property and casualty
insurance business; (vi) make reasonably available officers of the Business to
assist the Purchaser and its investment bankers in connection with any
"roadshows" conducted in connection with any financing arrangements necessary
for the Purchaser to consummate the transactions contemplated by this Agreement;
and (vii) request PricewaterhouseCoopers LLP to deliver "comfort" letters in
respect of financial statements or financial information as are customary in
connection with such financing arrangements. The foregoing matters relating to
transitional planning shall be subject to the terms and conditions of the Seller
Confidentiality Agreement and the Purchaser Confidentiality Agreement and shall
be subject to all other legal limitations (including attorney-client and work
product privileges, confidentiality, antitrust and

                                       53

fair trade limitations). Each of the parties hereto shall cooperate in
implementing the provisions of this Section 4.3(c) so as to not unreasonably
interfere with the Purchaser's or CIGNA's or their respective subsidiaries' (or
any of their successors') business operations.

                   (4)  Following the Closing Date and until the earlier to
occur of (i) the termination of certain obligations under this Agreement in
respect of remaining Deferred Assets pursuant to Section 8.4 hereof or (ii) all
of the Deferred Assets being conveyed to the Purchaser, the provisions of this
Section 4.3 shall continue to be binding upon the parties hereto in respect of
any Deferred Assets that may exist from time to time.

          Section 1.51  Post-Closing Access.
                        -------------------

                   (1)  Following the Closing Date, CIGNA and its subsidiaries
shall (i) allow the employees and representatives of the Purchaser, upon
reasonable prior notice and during regular business hours, the right, at the
Purchaser's expense, to examine and make copies of any Books and Records
relating to the Business which were retained by CIGNA or any of its subsidiaries
for any reasonable purpose relating to the Business, including, without
limitation, the preparation or examination of the Purchaser's Tax Returns,
regulatory filings and financial statements and the conduct of any litigation or
regulatory dispute, whether pending or threatened, concerning the conduct of the
Business prior to the Closing Date or any Subsequent Closing Date (if any), as
the case may be, and (ii) maintain such Books and Records for the Purchaser's
examination and copying for a period of not less than ten years following the
later of the Closing Date or the last Subsequent Closing Date (if any), provided
that after such period CIGNA shall provide the Purchaser with at least twenty
business days' written notice prior to destroying or otherwise disposing of any
such Books and Records, at which time and at the option and expense of the

                                       54
<PAGE>

Purchaser, the Sellers shall deliver such Books and Records to the Purchaser
rather than destroying the same. Access to such Books and Records shall be at
the Purchaser's expense and may not unreasonably interfere with CIGNA's or any
of its subsidiaries' (or any of their successors') business operations.
Notwithstanding anything to the contrary contained in this Section 4.4(a), the
Purchaser may not exercise its rights under this Section 4.4(a) in respect of
any Deferred Assets that, from time to time, have not been conveyed to the
Purchaser until such time as they have been conveyed to the Purchaser.

                  (2)   Following the Closing Date, the Purchaser shall (i)
allow CIGNA and its subsidiaries, upon reasonable prior notice and during
regular business hours, through their employees and representatives, the right,
at the expense of CIGNA, to examine and make copies of the Books and Records
transferred to the Purchaser at the Closing or any Subsequent Closing for any
reasonable business purpose relating to their respective businesses, including,
without limitation, the preparation or examination of Tax Returns, regulatory
filings and financial statements or the conduct of any litigation or regulatory
dispute, whether pending or threatened, and (ii) maintain such Books and Records
for examination and copying by CIGNA and its subsidiaries for a period of not
less than ten years following the later of the Closing Date or the last
Subsequent Closing Date (if any), provided that after such period the Purchaser
shall provide CIGNA with at least twenty business days' written notice prior to
destroying or disposing of any such Books and Records at which time and at the
option and expense of CIGNA, the Purchaser shall deliver such Books and Records
to CIGNA, rather than destroying the same. Access to such Books and Records
shall be at CIGNA's expense and may not unreasonably interfere with the
Purchaser's or any of its subsidiaries' (or any of their successors') business
operations.

<PAGE>

               (1)   The parties hereto shall (i) cooperate and use their
Reasonable Best Efforts to obtain all consents, approvals and agreements of all
Governmental Entities necessary to authorize, approve or permit the consummation
of the transactions contemplated by this Agreement and the Ancillary Agreements
at the earliest possible time hereafter, (ii) as promptly as practicable
hereafter, file or submit, or cause to be filed or submitted, to all
Governmental Entities all notices, applications, documents and other materials
necessary in connection with the consummation of such transactions and (iii) use
their respective Reasonable Best Efforts to respond as promptly as practicable
to all inquiries received from all Governmental Entities for additional
information or documentation in connection with such transactions. CIGNA and the
Purchaser shall promptly advise each other upon receiving any communication from
any Governmental Entity whose consent or approval is required for consummation
of the transactions contemplated by this Agreement and the Ancillary Agreements
which constitutes a reasonable likelihood that any requisite regulatory approval
will not be obtained or that receipt of any such approval will be materially
delayed. CIGNA and the Purchaser shall furnish to the other such necessary
information and reasonable assistance as the other may reasonably request in
connection with its preparation of necessary filings or submissions to any
Governmental Entity. CIGNA and the Purchaser shall provide the other with draft
copies and as-filed copies of all filings and submissions with Governmental
Entities and shall provide the other with a reasonable opportunity to comment
upon all such draft copies. CIGNA and the Purchaser agree that, to the extent
permitted and feasible and reasonable, all meetings with any Governmental Entity
(whether in person, by telephone or other means of instantaneous communication)
regarding the transactions contemplated hereby or by the Ancillary Agreements
shall include representatives of CIGNA and the Purchaser unless such parties
jointly decide otherwise. Nothing in this Agreement is intended to require that
any party

                                       56
<PAGE>

hereto or any of their respective affiliates pay any type of unlawful
consideration to obtain the approval or consent of any Governmental Entity. The
parties hereto agree that to the extent that the existence of any Replacement
Reinsurance would prevent or materially delay obtaining any consents, approvals
or agreements of Governmental Entities necessary to authorize, approve or permit
the consummation of the transactions contemplated by this Agreement or the
Ancillary Agreements, the Purchaser shall take all steps and actions necessary
to remove such impediment or delay.

               (2)   Without limiting the generality of the foregoing, the
parties hereto agree to use their respective Reasonable Best Efforts to
consummate the Closing on or before June 30, 1999, it being acknowledged and
agreed by the parties that time is of the essence.

               (3)   Notwithstanding anything in this Agreement to the contrary
(including Section 5.9(b) hereof), in no event shall the Purchaser be obligated
to accept any condition or requirement imposed by a Governmental Entity relating
to the acquisition, ownership or operation of the Business by the Purchaser
which, either alone or together with all such other conditions or requirements,
materially and adversely affects the benefits, taken as a whole, which the
Purchaser would otherwise receive from the transactions contemplated by this
Agreement had all such conditions and requirements not been imposed; provided,
                                                                     --------
however, that (i) in considering whether or not such conditions or requirements
- -------
materially and adversely affects such benefits, no consideration shall be given
to any conditions or requirements that relate to the Seller Guarantee or the
Replacement Reinsurance and (ii) in considering the benefits that the Purchaser
receives from the transactions contemplated by this Agreement, such benefits
shall not include the benefits under the Seller Guarantee and the Replacement
Reinsurance.

        Section 1.53  Non-Governmental Consents and Reasonable Best Efforts.
                      -----------------------------------------------------

                (1)   The Sellers and the Purchaser shall cooperate and use
Reasonable Best Efforts to obtain all required approvals and consents of non-
governmental persons to the transactions contemplated by this Agreement and the
Ancillary Agreements, and CIGNA and the Purchaser each agree to pay 50% of the
aggregate consideration mutually agreed to be paid to all non-governmental
persons in connection therewith. Nothing in this Agreement is intended to
require that any party hereto or any of their respective affiliates pay any type
of unlawful consideration to obtain the approval or consent of any non-
governmental person.

                (2)   To the extent permitted by any agreement, arrangement or
license which constitutes part of the Acquired Assets (such agreements,
arrangements and licenses, the "Acquired Asset Contracts"), or to the extent
consented to by all other parties to such Acquired Asset Contract, at the
Closing, CIGNA and its subsidiaries shall execute and deliver such instruments
of transfer, and take such further action as the Purchaser and CIGNA may
reasonably deem necessary in order to effectively transfer, convey and assign to
the Purchaser such Acquired Asset Contracts and all of CIGNA's and it
subsidiaries' rights thereunder, and the Purchaser shall execute such
instruments of assumption in order to effectively assume all of the obligations
of CIGNA and its subsidiaries thereunder. In the event and to the extent that at
the Closing CIGNA and its subsidiaries are unable to obtain any such required
consents under any of the Acquired Asset Contracts (the "Unassigned Acquired
Asset Contracts"), to the extent permitted by Law, during the period from the
Closing until the Subsequent Closing upon which such Unassigned Acquired Asset
Contract is conveyed to the Purchaser: (i) CIGNA and its subsidiaries, as the
case may be, shall, to the extent such Unassigned Acquired Asset Contracts
continue to be in force, continue to be bound

                                       58
<PAGE>

thereby; (ii) the Purchaser shall pay, perform and discharge fully all of the
obligations of CIGNA and its subsidiaries thereunder from and after the Closing;
and (iii) CIGNA and the Purchaser and their respective subsidiaries shall
continue to use Reasonable Best Efforts to obtain all such unobtained consents
at the earliest practicable date following the Closing. CIGNA and its
subsidiaries shall, without further consideration therefor, pay, assign and
remit to the Purchaser all monies, rights and other consideration received in
respect of the performance by the Purchaser of the obligations under such
Unassigned Acquired Asset Contracts. CIGNA and its subsidiaries shall use
Reasonable Best Efforts to exercise or exploit the rights under all such
Unassigned Acquired Asset Contracts only as reasonably directed in writing by
the Purchaser and at the Purchaser's expense, and the Purchaser shall indemnify
and hold harmless CIGNA and its subsidiaries against all Losses resulting from
any actions taken by CIGNA or its subsidiaries in connection with such
Unassigned Acquired Asset Contracts in accordance with the directions of the
Purchaser. Except with respect to the exercise or exploitation of the rights
under the Unassigned Acquired Asset Contracts at the direction of the Purchaser,
CIGNA and its subsidiaries shall have no obligation hereunder to pay, perform or
discharge any obligations under any such Unassigned Acquired Asset Contract
after the Closing, and the Purchaser shall indemnify and hold harmless CIGNA and
its subsidiaries from all Losses relating thereto. If and when the necessary
consents shall be obtained or such Unassigned Acquired Asset Contract shall
otherwise become assignable, then CIGNA and its subsidiaries, as the case may
be, shall promptly assign such Unassigned Acquired Asset Contract and all its
rights and obligations thereunder to the Purchaser without payment of further
consideration and the Purchaser shall, without the payment of any further
consideration therefor, assume all of such party's obligations thereunder.

                (1)   Upon the terms and subject to the conditions herein
provided, until the Closing Date or, if any Deferred Assets exist following the
Closing, until the earlier to occur of (i) the termination of certain
obligations under this Agreement in respect of remaining Deferred Assets
pursuant to Section 8.4 hereof or (ii) all of the Deferred Assets being conveyed
to the Purchaser, each of the parties hereto shall use Reasonable Best Efforts
to take, or cause to be taken, all actions or do, or cause to be done, all
things or execute any documents necessary, proper or advisable under Laws to
consummate and make effective the transactions contemplated by this Agreement
and the Ancillary Agreements.

                (2)   On and after the Closing Date, the Sellers, as reasonably
requested from time to time by the Purchaser, and the Purchaser, as reasonably
requested from time to time by any of the Sellers, shall take all reasonably
appropriate action and execute any additional documents, instruments or
conveyances of any kind (not containing additional representations and
warranties) which may be reasonably necessary to carry out any of the provisions
hereof, including, without limitation, putting the Purchaser in full possession
and operating control of the Acquired Assets and the Business and causing the
Purchaser to have full unencumbered ownership of all of the Acquired Securities,
and giving effect to the assumption of the Assumed Liabilities by the Purchaser
as contemplated hereby.

this Agreement, the parties to this Agreement shall bear their respective costs

performance of this Agreement and the Ancillary Agreements and the transactions

                          -----------------

                    (1)   CIGNA shall, and shall cause each of the Acquired
Companies to, use Reasonable Best Efforts to keep in effect the Insurance
Policies or substantially comparable insurance polices until the Closing or the
Subsequent Closing on which the relevant Acquired Company is conveyed to the
Purchaser. CIGNA shall terminate the Third Party Insurance Policies in respect
of each Acquired Company as of the Closing or the Subsequent Closing on which

Company is conveyed to the Purchaser.

                    (2)   The Sellers shall cause the Acquired Companies to

conveyed to the Purchaser to execute such an endorsement with respect to such
Self-Insurance Policies.

Closing Date or the Subsequent Closing Date, as the case may be, which were

bonds and statutory bonds. In the event certain of such surety bonds cannot be
replaced prior to the Closing Date or the Subsequent Closing Date, as the case

practicable thereafter, and the Purchaser shall indemnify and hold harmless the
Sellers for any liability relating such surety bonds incurred after the Closing
Date or the Subsequent Closing Date, as the case may be.

          Section 1.66  Affected Employees.
                        ------------------

                  (1)   The Purchaser shall cause the Acquired Domestic
Companies to continue to employ effective as of the Closing each person who is
an employee (such employees, other than the Excluded Domestic Employees, the
"Affected Domestic Employees") of any of the Acquired Domestic Companies as of
the Closing, other than those employees set forth in Section 5.1(a) of the
Seller Disclosure Schedule (the "Excluded Domestic Employees"), on terms
comparable to those provided on the date hereof to such employee. Prior to the
Closing, CIGNA or its subsidiaries shall transfer the Excluded Domestic
Employees from, or otherwise cause the Excluded Domestic Employees to cease to
be employed by, the Acquired Domestic Companies.

                  (2)   The Purchaser shall cause the Acquired International
Companies to continue to employ effective as of the Closing or effective as of
any Subsequent Closing on which the Acquired International Company was conveyed
to the Purchaser, as the case may be, each person who is an employee (such
employees, other than the Excluded International Employees, the

                                       68
<PAGE>

"Affected International Employees") of any of the Acquired International
Companies as of the Closing or a Subsequent Closing, as the case may be, other
than those employees set forth in Section 5.1(b) of the Seller Disclosure
Schedule (the "Excluded International Employees" and, together with the Excluded
Domestic Employees, the "Excluded Employees"), on terms comparable to those
provided on the date hereof to such employee. Prior to the Closing or the
Subsequent Closing, as the case may be, CIGNA or its subsidiaries shall transfer
the Excluded International Employees from, or otherwise cause the Excluded
International Employees to cease to be employed by, the Acquired International
Companies conveyed to the Purchaser.

               (3)   Prior to the Closing, the Purchaser shall offer employment
effective as of the Closing to each of the employees of CIGNA and its
subsidiaries (other than the Acquired Companies) set forth on Section 5.1(c) of
the Seller Disclosure Schedule (the "Identified Additional Employees") on terms
comparable to those provided on the date hereof to such employee. The
Purchaser's offer of employment to each of the Identified Additional Employees
shall be in writing, shall contain such terms as CIGNA may reasonably request
and shall otherwise be subject to the approval of CIGNA, which approval shall
not be unreasonably withheld. The Sellers will provide such reasonable
information as the Purchaser may request to confirm that each of the Identified
Additional Employees has committed substantial amounts of his or her time to the
Business in 1998. The parties hereto agree that the Purchaser shall have until
the forty-fifth day following the date of this Agreement to identify any
Identified Additional Employees who have not committed substantial amounts of
his or her time to the Business in 1998 and the Sellers shall reasonably
cooperate with the Purchaser in connection therewith. In the event that the
Purchaser has identified to the reasonable satisfaction of the Sellers any
Identified Additional Employees who have not committed substantial amounts of
his or her time to the Business in 1998, then such

                                       69
<PAGE>

employees shall be treated as Excluded Employees for all purposes of this
Agreement unless the Purchaser subsequently designates any such employee as a
Transitional Service Employee.

              (4)   Section 5.1(d) of the Seller Disclosure Schedule sets forth
a list by department or function of the equivalent number of full-time employees
in such department or in respect of such function providing services to the
Business in 1998. No later than ninety days prior to the anticipated Closing
Date, the Seller shall deliver a written list to the Purchaser specifying for
each such department or function the name of each employee in such department or
function that the Sellers propose that the Purchaser offer employment to as of
the Closing (the "Potential Additional Employees"); provided, however, that the
                                                    --------  -------
number of employees in each such department or function specified by the Sellers
shall not exceed the equivalent number of full-time employees for such
department or function specified in Section 5.1(d) of the Seller Disclosure
Schedule. Within 30 days of the Purchaser's receipt of the list of Potential
Additional Employees, the Purchaser shall deliver a written list to CIGNA
setting forth those Potential Additional Employees it desires to offer
employment to as of the Closing (the "Designated Additional Employees" and,
together with the Affected Domestic Employees, the Affected International
Employees and the Identified Additional Employees, the "Affected Employees") and
those of the Potential Additional Employees the Purchaser desires that the
Sellers continue to employ to provide services to the Acquired Companies
conveyed to the Purchaser pursuant to the Transition Services Agreement (the
"Transitional Services Employees"). Prior to the Closing, the Purchaser shall
offer employment effective as of the Closing to each of the Designated
Additional Employees on terms comparable to those provided on the date hereof to
such employee. The Purchaser's offer of employment to each of the Designated
Additional Employees shall be in writing, shall contain such terms as CIGNA may
reasonably request and shall otherwise be subject to the

                                       70
<PAGE>

approval of CIGNA, which approval shall not be unreasonably withheld.

               (5)   Notwithstanding anything to the contrary in this Agreement,
the Purchaser shall be liable for any and all obligations and liabilities in
respect of the Affected Employees and the Transitional Services Employees
arising under any Law (including the Worker Adjustment and Retraining
Notification Act of 1988 ("WARN Act")) or arising under any employee severance
plan or agreement of the Purchaser or its subsidiaries (including all of the
Acquired Companies conveyed to the Purchaser). Moreover, notwithstanding
anything to the contrary in this Agreement, the Purchaser shall indemnify and
reimburse CIGNA for any obligations and liabilities incurred by CIGNA and its
subsidiaries in respect of the Affected Employees and the Transitional Services
Employees arising under (i) any Law or (ii) any employee severance plan or
agreement of CIGNA or its subsidiaries; provided, however, that in the event
                                        --------  -------
that any such employee severance plan or agreement has been amended to provide
greater benefits than were provided at the date of this Agreement, then, in
respect of clause (ii) only, the Purchaser shall only be liable for those
obligations and liabilities arising under such employee severance plan or
agreements as were in effect as of the date of this Agreement.

               (6)   Notwithstanding anything to the contrary in this Agreement,
each of CIGNA and the Purchaser shall be liable for 50% of all obligations and
liabilities in respect of the Potential Additional Employees who do not
constitute Designated Additional Employees or Transitional Services Employees
(the "Remaining Employees"), arising under (i) any Law (including the WARN Act)
or (ii) any employee severance plan or agreement of CIGNA or its subsidiaries;
provided, however, that in the event that any such employee severance plan or
- --------  -------
agreement has been amended to provide greater benefits than were provided at the
date of this Agreement, then, in respect of clause (ii) only, the Purchaser
shall only be liable for 50% of the

                                       71
<PAGE>

obligations and liabilities arising under such employee severance plan or
agreements as were in effect as of the date of this Agreement. The Purchaser
shall indemnify and promptly reimburse CIGNA for any of the Purchaser's share of
the obligations and liabilities specified in the immediately preceding sentence.

                  (7)   Prior to the Closing Date, the Sellers shall promptly
provide to the Purchaser, upon the Purchaser's reasonable request and to the
extent permitted by Law, any information or copies of personnel records held by
the Sellers relating to the Affected Employees. The Sellers and the Purchaser
shall each cooperate with each other and shall provide to the other such
documentation, information and assistance as is reasonably necessary to effect
the provisions of this Section 5.1. Notwithstanding anything to the contrary in
this Agreement, the Purchaser shall not be obligated to employ any Affected
Employee for any fixed period of time following the Closing.

          Section 1.67  Employee Benefits.
                        -----------------

                  (1)   Service Credit. The Purchaser shall give the Affected
                        --------------
Employees full credit, for purposes of eligibility, vesting and benefit accrual
under any employee benefit plans, programs or arrangements maintained by the
Purchaser, for the Affected Employees' service with CIGNA and its subsidiaries
to the same extent recognized by CIGNA and its subsidiaries immediately prior to
the Closing or the Subsequent Closing, as the case may be. The Purchaser shall
(i) waive all limitations as to preexisting conditions, exclusions and waiting
periods with respect to participation and coverage requirements applicable to
the Affected Employees under any welfare benefit plans that such employees may
be eligible to participate in after the Closing Date or, in the case of the
Affected International Employees employed by Acquired International Companies
not conveyed to the Purchaser on the Closing Date, the Subsequent Closing Date
on which such Acquired International Company was conveyed to the

                                       72
<PAGE>

Purchaser and (ii) provide each Affected Employee with credit for any co-
payments and deductibles paid prior to the Closing Date or the Subsequent
Closing Date, as the case may be, in satisfying any applicable deductible or
out-of-pocket requirements under any welfare plans that the Affected Employees
are eligible to participate in after the Closing Date or the Subsequent Closing
Date, as the case may be.

               (2)   Level of Benefits. During the period beginning on the
                     -----------------
Closing Date (or the Subsequent Closing Date, as the case may be) and ending on
December 31st of the first full calendar year following the Closing (or the
Subsequent Closing, as the case may be), except as provided below, the Purchaser
shall provide the Affected Employees with coverage and benefits pursuant to
employee benefit and compensation plans, programs and arrangements which are
substantially similar to the plans, programs and policies provided to the
Affected Employees on the date of this Agreement (including but not limited to
the Plans). Notwithstanding the generality of the foregoing, during such period,
the Purchaser shall (i) maintain severance plans, programs and arrangements
covering the Affected Employees, the terms and conditions of which shall be no
less favorable with respect to any Affected Employee than the severance benefit
plans, programs and arrangements that cover Affected Employees as in effect on
the date of this Agreement, (ii) provide to Affected Domestic Employees and
other Affected Employees who are United States expatriates a pension program
that provides benefits to the group of Affected Domestic Employees and other
Affected Employees who are United States expatriates that are substantially
similar in the aggregate to benefits that would be earned under the benefit
accrual formula in effect on the date of this Agreement under Part B of the
CIGNA Pension Plan and the CIGNA Supplemental Pension Plan and (iii) provide to
Affected Employees, both during and after employment with the Purchaser,
medical, dental and life insurance benefits that are substantially similar to
the medical, dental and life insurance benefits provided by CIGNA to

                                       73
<PAGE>

its current and former employees under programs in effect on the date of this
Agreement. The Purchaser shall be liable for and shall hold CIGNA, its officers,
directors, employees, agents and affiliates harmless from all severance costs
associated with the termination of employment of any Affected Employee following
the Closing Date or the Subsequent Closing Date, as the case may be.

               (3)   Deferred Compensation Plan.  Except for the obligation to
                     --------------------------
deliver shares of CIGNA Common Stock, the Purchaser shall assume all obligations
and liabilities for each Affected Employee under the Deferred Compensation Plan
of CIGNA Corporation (the "CIGNA Deferred Compensation Plan"), which amounts
shall be credited to a deferred compensation plan to be designated or
established by the Purchaser. Prior to the Closing Date (or the Subsequent
Closing Date, as the case may be) CIGNA shall take all action necessary to
retain all liabilities under the CIGNA Deferred Compensation Plan with respect
to all participants therein who are not Affected Employees and with respect to
the obligation to deliver shares of CIGNA Common Stock.

               (4)   Disability.  Liabilities under CIGNA's short- and long-term
                     ----------
disability plans (collectively, the "Disability Plans") with respect to Affected
Employees who are on disability leave pursuant to the Disability Plans (such
employees, the "Disability Leave Employees") as of the Closing Date or the
Subsequent Closing Date, as the case may be, shall be the responsibility of
CIGNA. If a Disability Leave Employee terminates disability leave and indicates
a desire to return to employment during the twelve-month period following the
Closing Date or the Subsequent Closing Date, as the case may be, the Purchaser
shall make a good faith effort to employ such for the Disability Leave Employee
on the basis set forth in Section 5.1 hereof, and if such employee is hired such
employee shall then be treated as an Affected Employee for purposes of this
Agreement.

                                       74
<PAGE>

               (5)  Effective as of the Closing Date (or the Subsequent Closing
Date, as the case may be), the Purchaser shall assume all assets and liabilities
under all Foreign Pension Plans covering Affected Employees. With respect to
such Foreign Pension Plans, CIGNA and the Purchaser agree to cooperate and use
their respective Reasonable Best Efforts to implement as of the Closing Date (or
Subsequent Closing Date, as the case may be) an equitable, appropriate and
efficient allocation of assets and liabilities thereunder as between Affected

                         ------------------

               (1)       For purposes hereof:

                    (1)    "CIGNA Restricted Stock Awards" shall mean all
     outstanding awards of restricted CIGNA Common Stock held by Affected
     Employees;

                    (2)    "CIGNA Restricted Stock Units" shall mean all
     outstanding CIGNA

                                       75
<PAGE>

     restricted stock units (including restricted stock units awarded under the
     CIGNA Stock Unit Plan and phantom shares awarded under the CIGNA
     International Share Program) held by Affected Employees;

                    (3)    "CIGNA Awards" shall mean all CIGNA Restricted Stock
     Awards and CIGNA Restricted Stock Units; and

                    (4)    "Eligible Grantee" shall mean any Affected Employee
     who holds a CIGNA Award immediately prior to the Closing Date (or
     Subsequent Closing Date, as the case may be).

               (2)       As soon as practicable following the date of this
Agreement, the Purchaser shall take such actions as may be required to adopt
three plans (the "Purchaser Stock Plan"), the terms and conditions of which
shall be substantially identical to the CIGNA Long-Term Incentive Plan (the
"CIGNA LTIP"), the CIGNA International Share Program and the CIGNA International
Stock Unit Plan respectively, under which the Purchaser shall (A) grant to each
Eligible Grantee restricted stock awards ("Substitute Restricted Stock Awards")
to replace any CIGNA Restricted Stock Awards held by such Eligible Grantee
immediately prior to the Closing Date (or Subsequent Closing Date, as the case
may be) which expire or terminate on the Closing Date (or Subsequent Closing
Date, as the case may be) and (B) grant to each Eligible Grantee restricted
stock units ("Substitute Restricted Stock Units" and, together with the
Substitute Restricted Stock Awards, the "Substitute Awards") to replace any
CIGNA Restricted Stock Units held by such Eligible Grantee immediately prior to
the Closing Date (or Subsequent Closing Date, as the case may be) which expire
or terminate on the Closing Date (or Subsequent Closing Date, as the case may
be).

               (3)       Each Substitute Restricted Stock Award granted to an
Eligible Grantee shall:

                                       76
<PAGE>

                    (1)    be for a number of ordinary shares, par value
     $0.041666667 per share of the Purchaser ("Purchaser Common Stock") equal to
     the number of shares of CIGNA Common Stock subject to the CIGNA Restricted
     Stock Award it replaces, multiplied by the Exchange Ratio, rounded down to
     the nearest whole number of shares; and

                    (2)    otherwise be subject to substantially the same terms
     and conditions as applicable to such CIGNA Restricted Stock Award.

               (4)       Each Substitute Restricted Stock Unit granted to an
Eligible Grantee shall:

                    (1)    be for a number of shares of Purchaser Common Stock
     equal to the number of shares of CIGNA Common Stock subject to the CIGNA
     Restricted Stock Unit it replaces, multiplied by the Exchange Ratio,
     rounded down to the nearest whole number of shares; and

                    (2)    otherwise be subject to substantially the same terms
     and conditions as applicable to such CIGNA Restricted Stock Unit.

               (5)       No later than 30 days following the receipt by CIGNA of
evidence that the Purchaser has made the substitute grants in accordance with
this Section 5.3, CIGNA shall pay to the Purchaser an amount in cash, determined
with respect to each CIGNA Restricted Stock Award and each CIGNA Restricted
Stock Unit, equal to the product of (i) the average of the high and low sales
price of CIGNA Common Stock on the New York Stock Exchange on the Closing Date,
(ii) the number of shares of CIGNA Common Stock to which such CIGNA Award
relates and (iii) a fraction, the numerator

                                       77
<PAGE>

of which is the number of whole months elapsed from the grant of such CIGNA
Award to the Closing Date and the denominator of which is the total number of
whole months required from the grant date for such CIGNA Award to vest. For
purposes of the preceding sentence, each portion of a CIGNA Award that has a
distinct vesting date shall be treated as a separate CIGNA Award.

               (6)       For purposes of this Agreement, "Exchange Ratio" means
an amount equal to the quotient determined by dividing (1) the average of the
closing prices per share of CIGNA Common Stock on the Composite Tape of the New
York Stock Exchange as reported in the Wall Street Journal for the Closing Date
and the four trading days immediately prior to the Closing Date by (2) the
average closing prices per share of Purchaser Common Stock on the Composite Tape
of the New York Stock Exchange as reported in the Wall Street Journal for the
Closing Date and the four trading days immediately prior to the Closing Date.

               (7)       As soon as practicable after the Closing Date (or
Subsequent Closing Date, as the case may be), the Purchaser shall deliver to
each Eligible Grantee an award document evidencing the grant of such award (the
"Grant Letter"), based upon a form which is substantially identical to CIGNA's
form of restricted stock grant letter and attachment or restricted stock unit
grant letter and attachment, as applicable. Each Grant Letter shall provide, in
such form reasonably acceptable to CIGNA, that the Eligible Grantee releases
CIGNA from any and all claims in any way related to the CIGNA Award which such
Substitute Award replaces.

               (8)       The Purchaser shall take all corporate action necessary
to reserve for issuance a sufficient number of shares of Purchaser Common Stock
for delivery upon exercise (or vesting, as the case may be) of the Substitute
Awards in accordance with this Section 5.3. On the Closing Date, the Purchaser
shall file a registration statement on Form S-8 (or any

                                       78
<PAGE>

successor or other appropriate form) with the Securities and Exchange Commission
with respect to the shares of Purchaser Common Stock subject to such Substitute
Awards and shall use its Reasonable Best Efforts to maintain the effectiveness
of such registration statement or registration statements (and maintain the
current status of the prospectus or prospectuses contained therein) for so long
as such Substitute Awards remain outstanding. With respect to those individuals
who, subsequent to the Closing Date (or Subsequent Closing Date, as the case may
be), are subject to the reporting requirements under Section 16(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), with respect
to the Purchaser, where applicable, the Purchaser shall administer the Purchaser
Stock Plan in a manner that complies with Rule 16b-3 promulgated under the
Exchange Act to the extent that the CIGNA LTIP complied with such rule prior to
the Closing Date (or Subsequent Closing Date, as the case may be).

          Section 1.69   Brandywine.  Subject to the terms and conditions of
                         ----------
this Section 5.4, at the Closing, the Sellers shall provide a guarantee to the
Purchaser in form and substance reasonably acceptable to the Sellers and the
Purchaser (the "Seller Guarantee"), as to the adequacy of the recorded reserves
for losses and loss adjustment expenses as of the Closing for certain Insurance
Company subsidiaries of Brandywine Holdings Corporation as well as with respect
to such other liabilities of the Domestic Insurance Companies as the Purchaser
may reasonably request (the "Guaranteed Reserves"). The Seller Guarantee shall
indemnify the Purchaser or the Purchaser's subsidiaries against unanticipated
increases in the Guaranteed Reserves in an aggregate amount as shall be agreed
to by the parties. In exchange for and in full replacement of the Seller
Guarantee, the Sellers may, at its option, obtain reinsurance (the "Replacement
Reinsurance") from a mutually agreed upon third-party reinsurer to directly
indemnify certain of the Domestic Insurance Companies against unanticipated
increases in the Guaranteed Reserves in the same aggregate amount as has been
agreed

                                       79
<PAGE>

pursuant to the second sentence of this Section 5.4. In the event that, for
whatever reason, Replacement Reinsurance has not been obtained at the Closing,
then the Seller Guarantee shall automatically be void ab initio and shall be of
no further force and effect immediately prior to the Closing without any action
on the part of any person, and the Sellers shall have no liability or obligation
whatsoever to the Purchaser or any subsidiary or affiliate of the Purchaser,
including, without limitation, the Purchaser's Insurance Company subsidiaries,
with respect to such Seller Guarantee.

          Section 1.70   Intellectual Property.  Except as provided for in the
                         ---------------------
Copyright Assignment or in the Trademark Assignment, the parties hereto agree
that the Purchaser is not purchasing, acquiring or otherwise obtaining any
right, title or interest in, to or under any intellectual property owned by the
Sellers, including, but not limited to, the Retained Intellectual Property, the
names "CIGNA" and "LINA" or any trade names, trademarks, identifying logos or
service marks related thereto or employing the words "CIGNA" and "LINA" or any
part or variation thereof or any confusingly similar trade name, trademark,
service mark or logo (including all registrations and applications relating
thereto). Notwithstanding the foregoing, the parties agree that during the
period from the Closing Date until 180 days after the Closing Date (the "Sell-
off Period"), the Acquired Companies shall be entitled to use, on a non-
exclusive basis, the Sellers' Intellectual Property set forth in Section 5.5 of
the Seller Disclosure Schedule (the "Trademarks and Logos") to the extent that
the Trademarks and Logos exist or are contained as of the date such Acquired
Company was conveyed to the Purchaser on any business cards, schedules,
stationery, displays, signs, promotional materials, manuals, forms, computer
software and other material used in the Business, without any obligation on the
part of the Purchaser to pay royalties or similar fees to CIGNA or its
subsidiaries during the Sell-off Period. The Purchaser agrees that: (i)
immediately

                                       80
<PAGE>

upon termination of the Sell-off Period, the Acquired Companies shall cease and
desist from all further use of the Trademarks and Logos and will adopt new trade
names, trademarks, identifying logos and service marks related thereto which are
not confusingly similar to the Trademarks and Logos; (ii) except as set forth in
this Section 5.5, neither the Purchaser nor any of its subsidiaries (including
all of the Acquired Companies conveyed to the Purchaser) nor any of their
affiliates shall make any use of the Trademarks and Logos; and (iii) any use of
the Trademarks and Logos by the Acquired Companies during the Sell-off Period
shall be in a manner which is identical or substantially identical to the manner
used prior to the Closing and shall not be used in any manner which could
degrade the quality of the Trademarks and Logos or could be misleading in any
manner. At the Closing and each Subsequent Closing (if any), as the case may be,
the Purchaser shall, and shall cause its subsidiaries to, make appropriate
filings with all Governmental Entities and any other applicable registries to
change the legal name and any d/b/a of any Acquired Company that contains any of
the Trademarks and Logos to a name that does not include any of the Trademarks
and Logos or words confusingly similar thereto.

Date (and regardless if any Subsequent Closings occur), CIGNA and its
subsidiaries shall not engage in (i) the property and casualty insurance
business in any jurisdiction in which the Sellers have transferred an Insurance
Company to the Purchaser pursuant to this Agreement or (ii) any direct writing
of accident and health insurance anywhere in the world where a property and
casualty Insurance Company which was transferred by the Sellers to the Purchaser
pursuant

                                       81

authority to write both life and property and casualty insurance business and
except in any jurisdiction where such business is written through a Lloyd's
syndicate under the arrangements carried on by the Sellers through their
Reinsurance Life, Accident and Health Division immediately prior to the Closing
("RLAH Activities"); provided, however, that the Sellers' investment in a
                     --------  -------
Lloyd's managing agency for the purpose of continuing to engage in RLAH
Activities shall not constitute engaging in the property and casualty insurance
business.

hereof to the contrary, CIGNA and its subsidiaries shall not be prohibited from:

          Section 1.74   Replacement Support Agreements; New Support Agreements.
                         ------------------------------------------------------

               (1)       To the extent permitted by Law, the Purchaser agrees to
deliver at the Closing and each Subsequent Closing at which any relevant
Acquired Asset is conveyed to the Purchaser, such agreements, instruments and
other documents (collectively, the "Replacement Support Agreements") as may be
necessary to assume all of CIGNA's and its affiliates' (other than the Acquired
Companies conveyed to the Purchaser) obligations under those Existing Support
Agreements in force in respect of the Acquired Assets conveyed to the Purchaser
at the Closing and each Subsequent Closing and set forth in Section 5.9(a) of
the Seller Disclosure Schedule or otherwise identified to the Purchaser by
CIGNA. The Replacement Support Agreements shall also contain provisions
releasing CIGNA and its affiliates from all such obligations. Without limiting
the foregoing, the Purchaser hereby agrees to indemnify and hold harmless CIGNA
and its affiliates from and against all obligations under all Existing Support
Agreements in respect of the Acquired Assets conveyed to the Purchaser. Each
Replacement Support Agreement shall be effective at the Closing or the
Subsequent Closing at which it is delivered. To the extent that any Governmental
Entity increases the obligations that the Purchaser must assume under any
Existing Support Agreement then, for purposes of this Agreement, such additional
obligations shall be subject to Section 4.5(c) hereof. Notwithstanding anything
to the contrary in this Agreement, the Purchaser shall not be obligated to
assume any obligations, or provide any indemnification, in respect of any person
under any Existing Support Agreement other than the Acquired Companies.

               (2)   Subject to Section 4.5(c) hereof, the Purchaser agrees to
deliver at the Closing and each Subsequent Closing at which any relevant
Acquired Asset is conveyed to the Purchaser, such Support Agreements as any
Governmental Entity may

                                       91
<PAGE>

require as a condition to approving the transactions contemplated by this
Agreement or the Ancillary Agreements (the "New Support Agreements").

          Section 1.75   Financing.  The Purchaser shall use its Reasonable Best
                         ---------
Efforts to obtain, at the Purchaser's reasonable discretion (but without such
discretion delaying or adversely affecting the consummation of the transactions
contemplated hereby), (i) the financing set forth in the Financing Commitment
Letter substantially upon the terms set forth therein or (ii) such alternative
financing as is sufficient to enable the Purchaser to consummate the
transactions contemplated by this Agreement, in the case of clauses (i) and
(ii), no later than the Closing. Notwithstanding anything to the contrary
contained in this Agreement, the parties hereto acknowledge and agree that any
failure by the Purchaser to obtain any financing (regardless of whether or not
the Purchaser has used its Reasonable Best Efforts to obtain financing or the
conditions contained in the Financing Commitment Letter have been fulfilled)
shall not be a condition precedent of the Purchaser to the Closing or any
Subsequent Closing and shall not relieve the Purchaser of its obligations to
consummate the transactions contemplated by this Agreement and the Ancillary
Agreements.

          Section 1.76   Persons Authorized to Act.  Prior to the Closing, the
                         -------------------------
Sellers shall deliver to the Purchaser (i) a true, correct and complete list of
the names and locations of all banks, trust companies, securities brokers and
other financial institutions at which each of the Acquired Companies has an
account or safe deposit box or maintains a banking, custodial, trading or other
similar relationship, (ii) a true, correct and complete list of each such
account, box and relationship, indicating in each case the account number and
the names of the respective officers, employees, agents or other similar
representatives of the Acquired Companies transacting business with respect
thereto and (iii) a true, correct and complete list of each person

                                       92
<PAGE>

authorized to draw on each such account, entitled to have access thereto or
authorized to borrow money (or furnish security for the same) therefrom.

          Section 1.77   Certain Insurance Certificates.  The Sellers shall
                         ------------------------------
request delivery at a reasonable time prior to the Closing of certificates from
the respective departments of insurance of the jurisdiction or domicile of each
of the International Insurance Companies evidencing the continued existence and
licensure of such International Insurance Company as an insurance company (it
being acknowledged that certain jurisdictions may not deliver such certificates
in the ordinary course).

          Section 1.78   Real Estate Matters.
                         -------------------

               (1)       The parties hereto acknowledge and agree that, as of
the date of this Agreement, a number of the properties (collectively, the
"Shared Properties") owned or leased by the Acquired Companies, or owned or
leased by CIGNA and its affiliates (other than the Acquired Companies), are used
and occupied jointly by such Acquired Companies, on the one hand, and by CIGNA
and its affiliates (other than the Acquired Companies), on the other. Following
the Closing or any Subsequent Closing upon which any relevant Acquired Company
is conveyed to the Purchaser, the Shared Properties shall continue to be used by
the Acquired Companies, on the one hand, and CIGNA and its affiliates (other
than the Acquired Companies), on the other, in accordance with the terms of the
Facilities Sharing Agreements.

               (2)       Notwithstanding anything contained in this Agreement to
the contrary, the Sellers and the Purchaser hereby acknowledge and agree that,
on or prior to the Closing Date, CIGNA shall cause certain of its affiliates to
assign their respective interests as tenants under certain leases of shared
property to an affiliate of CIGNA as more particularly described in Section 5.14
of the Seller Disclosure Schedule. Such assignments shall be made on the
Sellers' standard

                                       93
<PAGE>

terms, without payment of any additional fee or consideration, and shall include
a provision releasing the assignor from any and all liability under the relevant
lease.


                                  ARTICLE VI

                                  TAX MATTERS

          Section 1.79 Tax Elections Generally.  Without the prior written
                       -----------------------
consent of the Purchaser (which shall not be unreasonably withheld), none of the
Acquired Companies shall make or change any Tax election, change an annual Tax
accounting period, adopt or change any method of Tax accounting, enter into any
closing agreement, settle or compromise any Tax claim or assessment, surrender
any right to claim a Tax refund, consent to any extension or waiver of the
limitations period applicable to any Tax claim or assessment or take or omit to
take any other action except in the ordinary course of business consistent with
past practice, if any such action or omission referred to above would (i) have a
legally binding effect upon the Acquired Companies with respect to items in a
Post-Closing Tax Period (including, without limitation, under a closing
agreement pursuant to Section 7121 of the Code or a comparable provision under
state, local or foreign Law) and (ii) have the effect of increasing the Tax
liability of the Acquired Companies with respect to a Post-Closing Tax Period.
In connection with the Closing, none of the Purchaser or its affiliates, CIGNA
or its affiliates, and the Acquired Companies shall make an election under
Treasury Regulations Section 1.1502-76(b)(2)(ii)(B) (or any comparable provision
under state, local or foreign Law).

          Section 1.80 Tax Returns Prior to Closing. All material Tax Returns
                       ----------------------------
not required to be filed on or before the date hereof but required to be filed
on or before the Closing Date or the Subsequent Closing Date on which an
Acquired Company is conveyed to the

                                       94
<PAGE>

Purchaser will be timely filed in accordance with Law along with payment for all
Taxes shown to be due and owing and, as of the time of filing, will be true and
correct in all material respects and will be prepared in a manner consistent
with past practice.

          Section 1.81 Transfer Taxes.
                       --------------

               (a)  The Purchaser (including the Acquired Companies conveyed to
the Purchaser) shall be responsible for and shall timely pay all Transfer Taxes
specified in Section 4.8 hereof. The Purchaser shall prepare all such Tax
Returns, which shall be timely filed by the party legally responsible to do so,
and CIGNA will, and will cause its affiliates to, cooperate with the Purchaser.

               (b)  CIGNA shall be responsible for and shall timely pay all
Transfer Taxes specified in Section 4.8 hereof.

          Section 1.82 Termination of Acquired Companies' Obligations under the
                       --------------------------------------------------------
Tax Sharing Agreement. Except as set forth in this Section 6.4, CIGNA shall
- ---------------------
cause the Acquired Companies to terminate their respective rights and
obligations under the Tax Sharing Agreement as of the Closing Date.  At the
Closing, CIGNA shall deliver to the Purchaser documentation evidencing both the
termination of the rights and obligations of the Acquired Companies under the
Tax Sharing Agreement and the settlement of all outstanding balances (which
balances shall be determined in accordance with the Tax Sharing Agreement based
on estimates determined by CIGNA and consistent with past practice) between the
relevant companies (other than any balance due from one Acquired Company to
another Acquired Company, both of which are conveyed to the Purchaser on the
Closing Date).  Final settlement of all amounts due under the Tax Sharing
Agreement shall be made after the Closing Date as though the Acquired Companies
continued to be subject to Section 3 of the Tax Sharing Agreement.  The
obligations of the Acquired Companies under all other agreements

                                       95
<PAGE>

providing for the allocation or sharing of Taxes identified in Section 2.10 of
the Seller Disclosure Schedule shall be settled in the ordinary course of
business consistent with past practice.

          Section 1.83   Preparation of Tax Returns.
                         --------------------------

               (1)       CIGNA shall prepare and file (or shall cause to be
prepared and filed), and the appropriate Acquired Company shall pay (or cause to
be paid) all Taxes shown to be due and owing on, all Tax Returns required to be
filed by or on behalf of (i) any Acquired Domestic Company and any Acquired
International Company which is included in CIGNA's U.S. consolidated federal
Income Tax Return with respect to all Pre-Closing Tax Periods and (ii) any
Acquired International Company (except for those Acquired International
Companies covered by Section 6.5(a)(i)) with respect to all Pre-Closing Tax
Periods for which Tax Returns are due to be filed on or before the Closing Date,
and, as of the time of filing, will be true and correct in all material respects
and prepared in a manner consistent with past practices. The Purchaser shall or
shall cause the Acquired Companies to provide to CIGNA, as soon as such
information is available but in no event later than five months prior to the due
date (including extensions) for filing the Tax Return to which such information
relates (or as soon thereafter as is reasonably practicable), all information
regarding the Acquired Companies reasonably required to complete the Tax Returns
for which CIGNA has filing responsibility pursuant to this Section 6.5(a) for
any Pre-Closing Tax Period. The Purchaser shall cause the Acquired Companies to
provide any other Tax related information reasonably requested by CIGNA within
five business days of such request. All Tax Returns (or copies thereof) as to
which CIGNA has filing responsibility under this Section 6.5 shall be, if
reasonably practicable, provided to the Purchaser a reasonable amount of time
prior to the due date (including extensions) for filing that Tax Return, and, if
such Tax Return is not provided to Purchaser in a reasonable amount of time
prior to the

                                       96
<PAGE>

due date for filing that Tax Return, a draft of such Tax Return shall be
provided. If a draft of a Tax Return has been provided pursuant to the preceding
sentence, CIGNA shall provide the Purchaser with the final Tax Return as soon as
is practicable, along with a schedule indicating any changes from the draft Tax
Return. If the Purchaser has any dispute regarding any such Tax Return as
presented by CIGNA, such Tax Return shall be filed as prepared by CIGNA, and the
Purchaser thereafter shall be entitled to initiate a dispute under Section 6.12
hereof. The Purchaser shall prepare and file all other Tax Returns. The
Purchaser shall not file, or permit any affiliate to file, any amended Tax
Returns for any of the Acquired Companies with respect to Pre-Closing Tax
Periods without the prior written approval of CIGNA, which approval shall not be
unreasonably withheld. Nothing in the preceding sentence is intended to modify
the rights or obligations of any person under Section 6.6 hereof.

               (c)  Consistent with past practice, CIGNA shall include the
appropriate Acquired Domestic Companies and Acquired International Companies in
its United States consolidated federal Income Tax Return (and in any state or
local Tax Return filed on a similar basis) through the close of business on the
Closing Date.

          Section 1.84 Amended Tax Returns and Refund Claims.
                       -------------------------------------

               (1)     Any required amended returns relating to a Pre-Closing
Tax Period and any refund claims relating to a Pre-Closing Tax Period shall be
prepared by CIGNA and furnished to the relevant Acquired Company for approval
(which approval shall not be unreasonably withheld), execution and filing, at
least thirty days (30) prior to the due date (including extensions) of such
returns or claims. Without limiting the generality of the preceding sentence (or
the penultimate sentence of Section 6.5(a) hereof), neither the Purchaser nor
any of its affiliates shall file any

                                       97
<PAGE>

Tax Return (or any other document) which attempts to carry back to any Pre-
Closing Tax Period any item of income, loss, deduction or credit (including,
without limitation, any net operating loss) incurred, created or sustained
during any Post-Closing Tax Period.

               (d)  Any refunds or credits of Taxes of an Acquired Company for
any Pre-Closing Tax Period shall be for the account of CIGNA. Any refunds or
credits of Taxes of an Acquired Company for any Post-Closing Tax Period shall be
for the account of the Purchaser.

               (2)     The Purchaser shall promptly pay over to CIGNA (and shall
cause the Acquired Companies conveyed to the Purchaser to pay over to CIGNA) all
refunds received by the Purchaser or its affiliates to which CIGNA is entitled
under this Section 6.6. CIGNA shall promptly pay over to the Purchaser (and
shall cause its affiliates to pay over to the Purchaser) all refunds received by
CIGNA or its affiliates to which the Purchaser is entitled under this Section
6.6.

          Section 1.85 Cooperation on Tax Matters.  The Purchaser and CIGNA
                       --------------------------
shall, and shall cause their respective affiliates to, cooperate fully with one
another, as and to the extent reasonably requested by the other in connection
with the preparation and filing of any Tax Return and in any audit, litigation
or other proceeding with respect to Taxes, including granting powers of
attorney, as appropriate, in connection with audits.  Such cooperation shall
include the retention and (upon the other party's request) the provision of
records and information which are reasonably relevant to any such audit,
litigation or other proceeding and making employees available on a mutually
convenient basis to provide additional information and explanation of any
material provided hereunder.  Notwithstanding anything in this Agreement to the
contrary, CIGNA shall not be required to provide the Purchaser CIGNA's Tax Books
and Records, including its United States Consolidated federal Income Tax Return,
which are not

                                       98
<PAGE>

directly related to the Acquired Companies conveyed to the Purchaser.

          Section 1.86 Tax Indemnification.
                       -------------------

               (a)  From and after the Closing Date, CIGNA shall be liable to,
and shall indemnify and hold harmless, the Purchaser Indemnitees (as defined in
Section 9.3(a) hereof) against the following Taxes: (i) with respect to any
Acquired Domestic Company and any Acquired International Company which is
included in CIGNA's U.S. consolidated federal Income Tax Return, Income Taxes
imposed on a Purchaser Indemnitee for a Pre-Closing Tax Period; provided,
                                                                --------
however, CIGNA shall not be required to indemnify Purchaser Indemnitees for any
- -------
state or local Income Taxes for any Tax period ending after December 31, 1998;
(ii) with respect to any Acquired International Company (except for those
Acquired International Companies covered by Section 6.8(a)(i)), Income Taxes due
and payable (including extension periods normally requested and granted) on or
before the Closing Date or the Subsequent Closing Date on which such Acquired
International Company was conveyed to the Purchaser and (iii) Taxes of the
Sellers or an affiliate of the Sellers (other than Taxes of an Acquired Company
not otherwise covered by this Section 6.8(a)) imposed on any Acquired Company
conveyed to the Purchaser by reason of Treasury Regulations Section 1.1502-6 (or
any comparable provision under state, local or foreign Law or limitation
imposing joint or several liability upon members of a consolidated, combined,
affiliated or unitary group), but solely with respect to any such liability of a
Pre-Closing Tax Period.  For purposes of this Agreement, a "Purchaser Tax Loss"
shall mean any and all amounts under clauses (i), (ii) and (iii) of the
immediately preceding sentence.

               (b)  The Purchaser shall be liable for, and shall indemnify and
hold the Seller Indemnitees (as defined in Section 9.4(a) hereof) harmless
against: (i) with respect to any Acquired Company conveyed to the Purchaser, any
and all Taxes imposed on any Seller

                                       99
<PAGE>

Indemnitee relating or apportioned to a Post-Closing Tax Period; (ii) loss
sustained by any Seller Indemnitee as a result (direct or indirect) of any
election by any Purchaser Indemnitee under Section 338 of the Code (or any
comparable provision under state, local or foreign Law); (iii) the breach of the
covenant set forth in Section 6.3(a) hereof; and (iv) any extraordinary item
arising from any action taken on the Closing Date after the Closing by any
Purchaser Indemnitee. For purposes of this Agreement, a "Seller Tax Loss" shall
mean any and all amounts under clauses (i), (ii), (iii) and (iv) of the
immediately preceding sentence.

               (c)  Any payment pursuant to this Section 6.8 shall be made not
later than the later of (i) 30 days after receipt by CIGNA or the Purchaser, as
the case may be, of written notice from the other party stating that any Tax
Loss has been paid by a Purchaser Indemnitee or a Seller Indemnitee, as the case
may be, and the amount thereof and of the indemnity payment requested, (ii) the
date on which such Purchaser Indemnitee or Seller Indemnitee is required to make
any payment in respect of any Tax Loss and (iii) the resolution of any dispute
regarding such item under Section 6.12 hereof.

               (d)  The Purchaser agrees to provide prompt written notice to
CIGNA of any Tax Loss or the assertion of any claim, or the commencement of any
suit, action or proceeding in respect of which indemnity may be sought hereunder
(specifying with reasonable particularity the basis therefor) and will provide
CIGNA such information with respect thereto as CIGNA may reasonably request.
CIGNA may, at its own expense, (i) participate in and (ii) except as provided in
Section 6.8(e) hereof (which describes, subject to the limitation contained
therein, the circumstances under which the Purchaser shall have the exclusive
right to control and compromise a Tax claim), upon notice to the Purchaser,
assume control over the defense of any such suit, action or proceeding
(including any Tax audit); provided, however, that (i) CIGNA shall from time to
                           --------  -------

                                      100
<PAGE>

time consult with the Purchaser upon the Purchaser's reasonable request therefor
with respect to such suit, action or proceeding (including any Tax audit) and
(ii) CIGNA shall not, without the Purchaser's consent (which shall not be
unreasonably withheld), agree to any settlement with respect to any Tax if such
settlement would, in a Post-Closing Tax Period (including, without limitation,
under a closing agreement pursuant to Section 7121 of the Code or any comparable
provision under any other Law), (1) have a legally binding effect with respect
to a Post-Closing Tax Period and (2) have the effect of increasing the Tax
liability of a Purchaser Indemnitee in respect of any Post-Closing Tax Period or
diminishing a Tax Asset of a Purchaser Indemnitee in respect of any Post-Closing
Tax Period. If CIGNA assumes such defense, the Purchaser shall have the right
(but not the duty) to participate in (but not control) the defense thereof to
the extent that the matter in dispute relates directly to any of the Acquired
Companies conveyed to the Purchaser; provided, however, nothing in this Section
                                     --------  -------
shall permit the Purchaser to participate in the defense of any Tax claim or
portion of any Tax claim (or be provided with any information or documentation
concerning a Tax claim, including, without limitation, CIGNA's United States
federal Income Tax Return) that relates to any affiliate of CIGNA which is not
an Acquired Company.  If CIGNA elects not to assume such defense, the Purchaser
may pay, compromise or contest the Tax at issue.  Whether or not CIGNA chooses
to defend or prosecute any claim, all of the parties hereto shall cooperate in
the defense or prosecution thereof.  The provisions of this Section 6.8(d) shall
be applied reciprocally, as appropriate, to indemnification claims made under
this Article VI by CIGNA or one of its affiliates, except as the context
otherwise requires.

               (e)  The Purchaser shall control the defense of any claim that
relates solely to a Post-Closing Tax Period. The Purchaser shall not, without
CIGNA's consent (which consent shall not be unreasonably withheld) agree to any
settlement with respect to any

                                      101
<PAGE>

Tax if such settlement would (i) have a legally binding effect with respect to
any Pre-Closing Tax Period and (ii) have the effect of increasing the Tax
liability or diminishing a Tax Asset of a Seller Indemnitee.

               (f)  Neither the Purchaser nor CIGNA shall be liable under this
Section 6.8 with respect to any Tax Loss resulting from a claim or demand the
defense of which such party was not offered the opportunity to assume as
provided under Section 6.8(d) hereof to the extent such party's liability under
this Section is materially adversely affected as a result thereof.

               (g)  Any claim of any Purchaser Indemnitee (other than the
Purchaser) under this Section may be made and enforced by the Purchaser on
behalf of such Purchaser Indemnitee, and CIGNA shall have reciprocal rights with
respect to the Seller Indemnitees.

          Section 1.87 Purchase Price Adjustment and Interest.  Any amount paid
                       --------------------------------------
by CIGNA or the Purchaser or their affiliates under this Article VI or Article
IX hereof shall be treated as an adjustment to the Purchase Price unless a Final
Determination causes any such amount not to constitute an adjustment to the
Purchase Price for Federal Tax purposes.  Any payment required to be made by the
Purchaser or CIGNA under Section 6.8 hereof that is not made when due shall bear
interest at the rate per annum determined, from time to time, under the

Acquired Company which constitutes a Section 1248 Company shall make any

Purchaser.  If either CIGNA or the Purchaser disagrees as to the amount of Taxes
- ---------
for which it (or one of its affiliates) may be liable under this Agreement,
CIGNA and the Purchaser shall promptly consult with each other to resolve such
dispute following their receipt of written notice from the other party to begin
such consultation (the "Consultation Notice").  If any such point of
disagreement cannot be resolved within 60 days of the date of receipt of the
Consultation Notice, CIGNA and the Purchaser shall within ten days after such
period jointly select a nationally recognized independent public accounting or
law firm (which does not have a conflict of interest with respect to the matter

arbitrator to determine, within 60 days after his or her selection, all points
of disagreement concerning Tax matters with respect to this Agreement which are
presented to such arbitrator for resolution at the time of his or her selection.
If the parties cannot agree on the selection of an accounting or law firm within
such ten-day period, they shall cause their respective accounting firms to

                                      103

select such accounting or law firm within five business days of the end of such
ten-day period, failing which either party may request the American Arbitration
Association to select the arbitrator who shall be a member of a nationally
recognized accounting or law firm with no less than 15 years of experience in
the practice of Tax law or Tax accounting.  The arbitration shall be conducted
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association then in effect except as modified herein.  Any arbitration award
shall be final and binding on the Purchaser and CIGNA and their respective
affiliates.  The fees of the arbitrator shall be divided equally between CIGNA
and the Purchaser.  CIGNA and the Purchaser shall, and the Purchaser shall cause
the Acquired Companies conveyed to it to, provide full cooperation to the
arbitrator.  The arbitrator shall not have the power to amend or modify this
Agreement.  The arbitration provided for in this Section 6.12 shall be subject
to Section 11.14 hereof.

          Section 1.91 Taxes on Transfers of Excluded Business and Deferred
                       ----------------------------------------------------
Companies.  Notwithstanding any other provisions of this Agreement (other than

Section 4.8 hereof), CIGNA shall be responsible for and pay all Taxes incurred
by the Purchaser or any Acquired Company which arise as a direct result of the
transactions contemplated by the Excluded Business Transfer Agreements or
incurred in connection with transfers or deemed transfers of Deferred Assets to
ensure that a Deferred Asset is not conveyed to the Purchaser at the Closing or
any Subsequent Closing.

          Section 1.92 Survival.  Notwithstanding anything in this Agreement to
                       --------
the contrary, the provisions of this Article VI shall survive for the full
period of all applicable statutes of limitations (giving effect to any waiver,
mitigation or extension thereof).

                                      129
<PAGE>

be made by such party or parties pursuant to this Agreement or the Ancillary

failure to disclose any Computer Software which, pursuant to the terms of such
representation or warranty, should have been disclosed; nor shall any such
Software Relicensing Fees be considered for purposes of determining whether the
1% threshold specified in Section 9.3(b) hereof has been satisfied.

          Section 1.106       Claims Notice.  In the event that either a

Purchaser Indemnitee or a Seller Indemnitee wishes to assert a claim for
indemnification hereunder, such party seeking indemnification (the "Indemnified
Party") shall deliver written notice (a "Claims Notice") to the other party (the
"Indemnifying Party") no later than thirty (30) business days after such claim
becomes known to the Indemnified Party, specifying the facts constituting the
basis for, and the amount (if known) of the claim asserted. Failure to deliver a
Claims Notice with respect to a claim in a timely manner as specified in the
preceding sentence shall not be deemed a waiver of the Indemnified Party's right
to indemnification hereunder for Losses in connection with such claim, but the
amount of reimbursement to which the Indemnified Party is entitled shall be
reduced by the amount, if any, by which the Indemnified Party's Losses would
have been less had such Claims Notice been timely delivered.

<PAGE>

               (1)       If an Indemnified Party asserts, or may in the future
seek to assert, a claim for indemnification hereunder because of an Action
instituted by any person not a party to this Agreement (a "Third Party
Claimant") that may result in a Loss with respect to which the Indemnified Party
would be entitled to indemnification pursuant to this Article IX (an "Asserted
Liability"), the Indemnified Party shall deliver to the Indemnifying Party a
Claims Notice with respect thereto, which Claims Notice shall, in accordance
with the provisions of Section 9.6 hereof, be delivered as promptly as
practicable and in any event no later than thirty (30) business days after such
Asserted Liability is actually known to the Indemnified Party. Failure to
deliver Claims Notice with respect to a claim in a timely manner as specified in
the preceding sentence shall not be deemed a waiver of the Indemnified Party's
right to indemnification hereunder for Losses in connection with such claim, but
the amount of reimbursement to which the Indemnified Party is entitled shall be
reduced by the amount, if any, by which the Indemnified Party's Losses would
have been less had such Claims Notice been timely delivered.

               (2)       The Indemnifying Party shall have the right, upon
written notice to the Indemnified Party, to investigate, contest, defend or
settle any Asserted Liability that may result in a Loss with respect to which
the Indemnified Party is entitled to indemnification pursuant to this Article
IX; provided, however, that the Indemnified Party may, at its option and at its
    --------  -------
own expense, participate in the investigation, contesting, defense or settlement
of any such Asserted Liability through representatives and counsel of its own
choosing; provided further, however, that the Indemnifying Party shall not
          -------- -------  -------
settle any Asserted Liability unless (i) such settlement is exclusively on
monetary terms and no obligation, admission, restriction or Loss shall be
imposed on the Indemnified Party or (ii) the Indemnified Party shall have
consented to the terms of such settlement, which

                                      131
<PAGE>

consent shall not be unreasonably withheld. If requested by the Indemnifying
Party, the Indemnified Party will, at the sole cost and expense of the
Indemnifying Party, cooperate with the Indemnifying Party and its counsel in
contesting any Asserted Liability or, if appropriate and related to the Asserted
Liability in question, in making any counterclaim against the Third Party
Claimant, or any cross-complaint against any person (other than the Indemnified
Party or its affiliates). Unless and until the Indemnifying Party elects to
defend the Asserted Liability, the Indemnified Party shall have the right, at
its option and at the Indemnifying Party's expense, to do so in such manner as
it deems appropriate; provided, however, that the Indemnified Party shall not
                      --------  -------
settle or compromise any Asserted Liability for which it seeks indemnification
hereunder without the prior written consent of the Indemnifying Party (which
shall not be unreasonably withheld).

               (3)       The Indemnifying Party shall be entitled to participate
in (but not to control) the defense of any Asserted Liability which it has not
elected to defend with its own counsel and at its own expense.

               (4)       CIGNA and the Purchaser shall make mutually available
to each other all relevant information in their possession relating to any
Asserted Liability (except to the extent that such action would result in a loss
of attorney-client privilege) and shall cooperate with each other in the defense
thereof.

          Section 1.108       Indemnification Payments.  Any payment hereunder
                              ------------------------
shall be made by wire transfer of immediately available funds to such account or
accounts as the Indemnified Party shall designate to the Indemnifying Party in
writing.

          Section 1.109       Exclusivity.  The Purchaser agrees, to the fullest
                              -----------
extent permitted by Law, that the Sellers and their subsidiaries and their

                                      132

agents or representatives shall not have any liability to the Purchaser or its
subsidiaries or any of their respective directors, officers, employees,

(including in contract or tort, under federal or state securities laws or

statements made (or any omissions therefrom), including any projections,

specific representations and warranties of the Sellers set forth in Article II
of this Agreement, except as and only to the extent expressly set forth in

subject to the limitations and restrictions contained in this Agreement
(including Article IX). The Sellers and the Purchaser hereby agree that, other
than the representations and warranties contained in Articles II and III hereof,
no representations or warranties are being made in this Agreement by any party
hereto. Following the Closing (and regardless if any Subsequent Closings occur),
the indemnities provided for in Sections 9.3 and 9.4 hereof shall be the
exclusive remedies of the parties to this Agreement and their respective
officers, directors, employees, affiliates, agents, representatives, successors
and assigns for any breach of or inaccuracy in any representation or warranty or
any breach, nonfulfillment or default in the performance of any of the covenants
or agreements contained in this Agreement (but not any such covenants or
agreements to the extent they are by their terms to be performed after the
Closing Date or any Subsequent Closing Date, as the case may be), and the
parties shall not be entitled to a rescission of this Agreement or to any
further indemnification rights or claims of any nature

                                      133

whatsoever in respect thereof, all of which the parties hereto hereby waive.

of The United States District Court for the Southern District of New York or, if
such court will not accept jurisdiction, the Supreme Court of the State of New
York or any court of competent civil jurisdiction sitting in New York County,
New York. In any action, suit or other proceeding, each of the parties hereto
irrevocably and unconditionally waives and agrees not to assert by way of
motion, as a defense or otherwise any claims that it is not subject to the
jurisdiction of the above courts, that such action or suit is brought in an
inconvenient forum or that the venue of such action, suit or other proceeding is
improper. Each of the parties hereto also agrees that any final and unappealable

party in its effort to obtain either an order to compel compliance with such
arbitration procedures or such orders, or an enforcement of the arbitration
award, from a court of competent jurisdiction.

                                   ---
         WHEREAS, ACE and IBM have engaged in extensive negotiations,
discussions and due diligence that have culminated in the formation of the
contractual relationship described in this Agreement;

         WHEREAS, ACE desires to procure from IBM, and IBM desires to provide to
ACE, the information technology products and services described in this
Agreement, on the terms and conditions specified herein;

contained herein, and of other good and valid consideration, the receipt and
sufficiency of which is hereby acknowledged, ACE and IBM (collectively, the
"Parties" and each, a "Party") hereby agree as follows:
 -------               -----

1.       BACKGROUND AND OBJECTIVES

1.1      ACE desires that certain information technology services presently
         performed and managed by or for ACE, and certain additional information
         technology services, as each is described in this Agreement, be
         performed and managed by IBM. IBM has carefully reviewed ACE's
         requirements, has performed initial due diligence, and desires to
         perform and manage such information technology services for AC E.

1.2      The Parties acknowledge and agree that the specific goals and
         objectives of the Parties in entering into this Agreement are to:

         .    Align information technology with business drivers;

         .    Permit ACE to focus its internal resources on its core
              competencies;

         .    Accelerate the deployment of a single integrated information
              technology strategy;

         .    Provide better cost visibility and variability to ACE for improved
              cost management and information technology investment leverage;

         .    Reduce information technology assets as appropriate;

         .    Achieve cost savings consistent with IBM's representations to ACE
              regarding cost savings;

         .    Reduce the complexity of ACE's information technology
              organization;

         .    Obtain a fair return for IBM's shareholders for the Services
              provided and assets acquired; and

         .    Increase the scope of the Services to IBM by adding new recipients
              and new services.

                  shall be deemed to be included within the scope of the
                  Services to be delivered for the base Charges, as if such

                  shall be responsible for providing the facilities, personnel,

                  the Services.

         (b)      Implementing Post-Effective Date Due Diligence. During the
                  ninety (90) day period following the Commencement Date, IBM
                  and ACE reserve the right to inventory, validate and update
                  any information that is reflected in or omitted from this

                  regarding the information reflected in this Agreement, this
                  Agreement shall be amended, and there shall be equitable
                  adjustments to the Charges and the related Resource Baselines.
                  If either Party disputes the inaccuracy, then the Parties will

                  Date) and, (a) within ninety (90) days after the Commencement

                  (including any late payment penalties) occurring prior to
                  delivery of such notice and a copy of such agreement by ACE.

                  Services, and notwithstanding anything to the contrary
                  contained herein, this Agreement shall not be interpreted to
                  prevent ACE or any Eligible Recipient from obtaining from
                  third parties, or providing to itself, any or all of the
                  Non-Exclusive Services described in this Agreement. Nor shall
                  anything in this Agreement be construed or interpreted as
                  limiting ACE's right or ability during the Term to increase or
                  decrease the demand for Services, consistent with Schedule J.
                                                                    ----------

                       --------------
                  terminate, and ACE may not terminate pursuant to this Section
                                                                        -------

                  applications development services to develop a specified
                  application, ACE may not, by reference to this Section,
                  terminate such development. On the other hand, if ACE has not
                  yet selected the Entity that will perform such application
                  development services, because application development services
                  are Non-Exclusive Services, ACE may select IBM or any third
                  party or ACE to perform such services. If ACE selects IBM, IBM
                  will perform such services as specified in this Agreement.)

                  contrary herein, IBM acknowledges that ACE may obtain any of

                  Facilities Agreement until the expiration of the Transition
                  Period or the completion of ACE's separation from CIGNA,
                  whichever occurs later.

                           Equipment Leases and Third Party Contracts to ACE or
                           its designee as of the expiration or termination date
                           or the completion of any Services associated with
                           such Equipment or Third Party Contracts requested by
                           ACE under Section 4.3(b), whichever is later. IBM
                                     --------------
                           shall represent and warrant that such Equipment
                           Leases and Third Party Contracts used by IBM are not
                           in default and that all payments have been made
                           thereunder through the date of assignment.

                  (7)      For a period of six (6) months following the
                           expiration or termination date, IBM shall provide to
                           the Eligible Recipient(s), at ACE's written request
                           180 days prior to the expiration or termination date,
                           the Services being performed for such Eligible
                           Recipients by IBM prior to the expiration or
                           termination date. In addition, at ACE's written
                           request 180 days prior to the expiration or
                           termination date, and provided that ACE is pursuing a
                           migration of some or all of the Services to itself or
                           a third party, IBM shall provide to the Eligible
                           Recipient(s) such Services for an additional period
                           not to exceed six (6) months from the end of such six
                           (6) month period. To the extent ACE requests such
                           Services, ACE will pay IBM the Charges specified in
                           Schedule J that ACE would have been obligated to pay
                           ----------
                           IBM for such Services if this Agreement had not yet
                           expired or been terminated.

                  (8)      If IBM uses a proprietary communications network to
                           provide Services to ACE or the Eligible Recipients,
                           then for a period of no more than six (6) months
                           following the expiration or termination date, ACE may
                           request that IBM continue to provide such proprietary
                           communications network Services at the rates
                           available to IBM.

                  (9)      Except as provided in Sections 4.3(b)(7) and (8), if
                                                 -------------------------
                           ACE requests that IBM provide or perform Transfer
                           Assistance Services in accordance with this
                           Agreement, ACE will pay IBM the rates and charges
                           specified in Schedule J for IBM Personnel or
                                        ----------
                           resources required to perform such Transfer
                           Assistance Services. If Transfer Assistance Services
                           require additional resources beyond those being used
                           to provide the Services, ACE will pay IBM for such
                           usage as a New Service.

         (c)      Survival of Terms. This Section 4.3 shall survive
                                          -----------
                  termination/expiration of the Term.

5.       REQUIRED CONSENTS

         (a)      ACE shall obtain all Required Consents. Each party shall pay
                  fifty percent (50%) of any fees (such as transfer, relicensing
                  or upgrade fees) associated with obtaining any Required
                  Consents and any other costs that result from the termination
                  or underutilization of any agreement with a third party (the
                  "Required Consent Costs"); provided, however, that ACE shall
                   ----------------------
                  not be required to pay more than two million ($2,000,000)
                  dollars as Required Consent Costs and IBM shall be responsible
                  for all Required Consent Costs after ACE has paid such amount.
                  IBM shall undertake all administrative activities necessary to
                  obtain the Required Consents. If ACE requests, IBM will
                  cooperate with ACE

                        Ace/IBM Proprietary Information
                                      15
<PAGE>

                  in obtaining the Required Consents by executing certain
                  written communications and other documents prepared or
                  provided by ACE.

         (b)      If, despite using commercially reasonable efforts, ACE is
                  unable to obtain a Required Consent, then, unless and until
                  such Required Consent is obtained, IBM and ACE shall use
                  commercially reasonable efforts to determine and adopt,
                  subject to ACE's prior approval, such alternative approaches
                  as are necessary and sufficient for IBM to provide the
                  Services without such Required Consent. If such alternative
                  approaches are required for a period longer than ninety (90)
                  days following the Commencement Date, the Parties will
                  equitably adjust the terms and reduce the prices specified in
                  this Agreement to reflect any additional costs being incurred
                  and any Services not being received by ACE and the Eligible
                  Recipients. In addition, if, pursuant to the above, the
                  Parties fail to obtain a Required Consent or an acceptable
                  alternative approach within ninety (90) days of the
                  Commencement Date and such failure has a material adverse
                  impact on the use or enjoyment of the Services by ACE or the
                  Eligible Recipients, ACE will terminate the Agreement or any
                  affected portion thereof without payment of any Termination
                  Charges; provided, however that ACE will reimburse IBM with
                  respect to related Acquired Assets for payment by ACE of the
                  associated portions of the Acquired Assets Credit. IBM and ACE
                  will discuss whether the termination will be of the Agreement
                  or the affected portion. Upon any such termination, IBM shall
                  sell and assign the Acquired Assets back to ACE. Each Party
                  agrees that it shall not allege that a failure to obtain a
                  Required Consent after using the efforts required under this
                  Section 5 is a breach of this Agreement.
                  ---------

6.       FACILITIES, SOFTWARE, EQUIPMENT, CONTRACTS AND ASSETS ASSOCIATED WITH
         THE PROVISION OF SERVICES

6.1      Service Facilities

         (a)      Service Facilities. The Services shall be provided at or from
                  (i) the data centers and other service locations owned or
                  leased by ACE and set forth on Schedule O.1, (ii) the data
                                                 ------------
                  centers and other service locations owned or leased by IBM or
                  its suppliers and set forth on Schedule O.2, (iii) any other
                                                 ------------
                  service location as may be agreed upon by IBM and ACE.

         (b)      ACE Facilities. ACE shall provide to IBM the use of and access
                  to the ACE Facilities (or equivalent space) set forth in
                  Schedule O.1 for the periods specified therein (or for those
                  ------------
                  portions of the Term of this Agreement during which such use
                  or access is necessary to perform the Services if not
                  otherwise specified). All ACE owned or leased assets provided
                  for the use of IBM under this Agreement shall remain in ACE
                  Facilities unless ACE otherwise agrees. In addition, all
                  leasehold improvements made for IBM during the Term shall be
                  and remain part of the ACE Facility. EXCEPT AS EXPRESSLY
                  PROVIDED HEREIN, THE ACE FACILITIES ARE PROVIDED BY ACE TO IBM
                  ON AN "AS-IS", "WHERE-IS" BASIS. ACE EXPRESSLY DISCLAIMS ANY
                  WARRANTIES, EXPRESSED OR IMPLIED, AS TO THE ACE FACILITIES, OR
                  THEIR CONDITION OR SUITABILITY FOR USE BY IBM. ACE will be
                  responsible for all leasehold improvements including cost and
                  completion. ACE is not required under this Agreement to make
                  any leasehold improvements.

         (c)      Furniture, Fixtures and Equipment. The office facilities
                  provided by ACE for the use of IBM Personnel will be generally
                  comparable to the office, storage and other space occupied by
                  similarly situated Transitioned Employees prior to the
                  Commencement Date. IBM shall be permitted to use the office
                  furniture, fixtures, telephone handsets and personal computers
                  being used by the Transitioned Employees as of the
                  Commencement Date. IBM shall be responsible for providing all
                  other office

                  furniture and fixtures needed by IBM or IBM Personnel to
                  provide the Services, and for all upgrades, replacements and
                  additions to such furniture, telephone handsets, personal
                  computers or fixtures. In the event that IBM purchases any of
                  the assets (personal computers or telephone handsets), ACE
                  shall not have any additional or continuing obligations
                  regarding the provision of such assets nor will IBM be
                  obligated to ACE to return or account for such assets. IBM
                  Personnel using the office facilities provided by ACE will be
                  accorded reasonable access to, and the use of at no cost to
                  IBM, certain shared office equipment and services, such as
                  photocopiers, telephone service for ACE-related calls, mail
                  service, office support service (e.g., janitorial), heat,
                  light, and air conditioning. IBM shall be responsible for
                  providing all other office, data processing and computing
                  equipment and services needed by IBM or IBM Personnel to
                  provide the Services, and for upgrades, improvements,
                  replacements and additions to such equipment or services. The
                  office, data processing and computing equipment and services
                  used by IBM or IBM Personnel in providing the Services shall
                  not be counted in calculating the Resource Units utilized by
                  ACE.

         (d)      ACE's Responsibilities Regarding Utilities and Facilities
                  Maintenance. Subject to reasonable usage by IBM, ACE and the
                  Eligible Recipients shall be responsible for paying for the
                  following for ACE Facilities used to provide Services: (i)
                  electricity supplied by the power utility company, (ii) water
                  supplied by the water utility company, (iii) natural gas
                  supplied by the natural gas utility company, (iv) local and
                  long distance telephone service, and (v) maintenance,
                  excluding any amounts to be paid by IBM under the terms of
                  Schedule J. In addition, ACE shall be responsible for
                  ----------
                  maintaining the account relationship with the power
                  utility company, the water utility company, the natural gas
                  utility company and the local telephone service provider. If
                  it wishes, ACE may identify and designate one or more
                  alternative sources from which to obtain power, water, natural
                  gas or local telephone services.

         (e)      IBM's Responsibilities Regarding Facilities. Except as
                  provided in Sections 6.1 (a), (b), (c) and (d), IBM shall be
                              ----------------------------------
                  responsible for providing all furniture, fixtures, Equipment,
                  space and other facilities required to perform the Services
                  and all upgrades, improvements, replacements and additions to
                  such furniture, fixtures, Equipment, space and facilities.
                  Without limiting the foregoing, IBM shall,except as provided
                  in Section 6.1(d), (i) provide site management, site
                     --------------
                  administration and similar services at the ACE Facilities, and
                  (ii) provide all necessary emergency power supply and
                  uninterrupted power supply services and all necessary
                  Equipment at IBM facilities. IBM shall not be responsible for
                  any failure to perform its obligations under this Section
                                                                    -------
                  6.1(e) arising as a direct result of any failure of ACE to
                  ------
                  perform its obligations under Section 6.1(d).
                                                --------------

         (f)      Physical Security. ACE is responsible for the physical
                  security of the ACE Facilities; provided, that IBM shall be
                                                  --------
                  responsible for compliance by IBM Personnel with the security
                  and safety standards and procedures that are enforced by ACE
                  and applicable to the ACE Facilities, provided that IBM
                  received a copy of such standards and procedures and has an
                  opportunity to review the same in advance of the commencement
                  of IBM's responsibility under this Section 6.1(f). Such
                                                     --------------
                  standards and procedures may be modified by ACE from time to
                  time subject to the New Services provision of the Agreement.

         (g)      Employee Services. Subject to applicable security
                  requirements, ACE will permit IBM Personnel to use all
                  employee facilities (e.g., parking, cafeteria, and common
                  facilities) at the ACE Facilities that are generally made
                  available to the employees of ACE or the Eligible Recipients.
                  IBM Personnel will not be permitted to use such employee
                  facilities designated by ACE for the exclusive use of certain
                  ACE or Eligible Recipient employees.

         (h)      Use of ACE Facilities. Unless IBM obtains ACE's prior written
                  agreement, which may be withheld by ACE in its sole
                  discretion, IBM shall use the ACE Facilities only to provide
                  the Services to ACE and the Eligible Recipients. ACE reserves
                  the right to relocate a ACE Facility from which the Services
                  are then being provided by IBM to another geographic location;
                  provided that, in such event, ACE will provide IBM with
                  --------
                  comparable space, facilities and resources in the new location
                  at no cost to IBM. ACE shall also be responsible for the
                  reasonable cost associated with such relocation including
                  personnel relocation, moving expenses and start-up and fit up
                  activities. In the event that such relocation impacts IBM's
                  ability to provide the Services in accordance with the Service
                  Levels, IBM shall be relieved from Service Levels until the
                  relocation is complete and the Service Levels are
                  appropriately adjusted by the Parties. ACE also reserves the
                  right to direct IBM to cease using all or part of the space in
                  a ACE Facility from which the Services are then being provided
                  by IBM and to thereafter use such space for its own purposes;
                  provided that, in such event,  ACE shall reimburse IBM for the
                  --------
                  incremental Out-of-Pocket Expenses incurred by IBM as a result
                  of such direction, and IBM shall not be responsible for any
                  failures of IBM to perform Services at the Service Levels
                  required by this Agreement to the extent such failures result
                  from such use or direction of ACE.

         (i)      Conditions for Return. When the ACE Facilities are no longer
                  to be used by IBM as contemplated by Section 6.1 or are
                                                       -----------
                  otherwise no longer required for performance of the Services,
                  IBM shall return them to ACE in substantially the same
                  condition (as they may have been improved) as when IBM began

     (b)  With respect to any such Software licenses, Equipment Leases or Third
          Party Contracts that can not, as of the Commencement Date, be assigned
          to IBM without breaching its terms or otherwise adversely affecting

          obligations shall be deemed to be subcontracted or delegated to IBM
          until any requisite consent, notice or other prerequisite to
          assignment can be obtained, given or satisfied by ACE. It is
          understood that, from and after the Commencement Date, IBM, as a
          subcontractor or delegatee, shall be financially, administratively and

          substitute or change vendors relating to goods or services covered
          thereby as IBM chooses so long as (i) such action does not increase
          the cost to ACE or any Eligible Recipient of obtaining from third
          parties, or providing itself, any New Services or services similar to
          the Services, at any time during the Term or thereafter, (ii) such
          action would not materially and adversely affect the ability of ACE or
          any Eligible Recipient to obtain from third parties, or to provide
          itself, any New Services, (iii) such action does not constitute a
          breach of any obligation of ACE or any Eligible Recipient under any
          Software license, Equipment Leases and Third Party Contracts, (iv)
          such action does not impose any Losses upon or result in any Losses to

          Services in the manner required by this Agreement. IBM's rights under
          the immediate preceding sentence are conditioned upon IBM paying all
          applicable termination charges, Losses and other amounts directly
          related to such termination or cancellation. IBM shall indemnify ACE
          and the Eligible Recipients for any payment they have made for such

     relevant licensor), IBM and its Subcontractors shall cease all use of such
     ACE Third Party Software and ACE Third Party Contracts when the Term and
     Transfer Assistance Services period ends.

6.10  Notice of Defaults

      ACE and IBM shall promptly inform the other Party of any breach of, or
      misuse or fraud in connection with, any Third Party Services Contract,
      Equipment Lease or Third Party Software license of which it becomes aware
      and shall cooperate with the other Party to prevent or stay any such
      breach, misuse or fraud.

6.11  Thornton Data Center

      IBM may purchase, or cause to be purchased, the Thornton Data Center,
      subject to mutually agreeable terms and conditions.

      If IBM does not purchase, or cause to be purchased, the Thornton Data
      Center, then IBM will require the use of the Thornton Data Center for the
      first Contract Year, (and ACE will permit such use, consistent with the
      use and access rights to which CIGNA is entitled under the Systems
      Facilities Agreement), and IBM (a) will lease from ACE or a third party
      the Thornton Data Center on commercially reasonable terms and conditions,
      and will be financially responsible for such lease, and (b) will credit a
      total of $2,000,000, split equally between the first and second Contract
      Years against application development services.

6.12  Systems Facilities Agreement

      Subject to the conditions set forth in Section 3.1 of the Systems
                                             -----------
      Facilities Agreement, IBM shall grant such full and unrestricted access to
      use the Acquired Assets at the locations specified in Section 3.1 of the
      Systems Facilities Agreement as ACE is required to grant pursuant to
      Section 3.1 of the Systems Facilities Agreement.
      -----------

7.    SERVICE LEVELS

7.1   General

      At all times, IBM shall perform the Services at levels of accuracy,
      quality, completeness, timeliness, responsiveness, productivity and user
      satisfaction that are equal to or higher than the levels of accuracy,
      quality, completeness, timeliness, responsiveness, cost-effectiveness,
      productivity and user satisfaction received by ACE or the Eligible
      Recipients prior to the Commencement Date. Without limiting the generality
      of the foregoing or the other obligations of IBM, on or before one hundred
      and eighty (180) days after the expiration of the Transition Period, the
      Parties will establish mutually acceptable Service Levels. IBM shall
      perform the Services so as to meet or exceed the Service Levels set forth
      in Schedule G.
         ----------

7.2   Service Level Credits

      IBM recognizes that its failure to meet critical Service Levels may have a
      material adverse impact on the business and operations of ACE and that the
      damages resulting from IBM's failure to meet such Service Levels may not
      be capable of precise determination. Accordingly, if IBM fails to meet any
      such Service Level for reasons other than the actions of ACE or
      circumstances that constitute Force Majeure, then, within thirty (30) days
      from the date that the failure is reported to ACE by IBM, ACE may notify
      IBM that it is reserving, and may exercise, its rights at law and in
      equity. In the event that ACE, in its sole discretion, elects to accept
      Service Level Credits for such failure, ACE shall not be entitled to other
      remedies as a result of IBM's failure to meet such Service Levels, and IBM
      shall pay ACE the performance credits specified in Schedule G ("Service
                                                         ----------   -------
      Level Credits").

7.3   Problem Analysis

      If IBM fails to provide Services in accordance with the Service Levels and
      the Agreement, IBM shall (i) promptly investigate and report on the causes
      of the problem; (ii) provide a Root Cause Analysis of such failure as soon
      as practicable after such failure (iii) develop and implement a plan to
      correct the problem and to begin meeting the Service Levels as soon as
      practicable; and (iv) advise ACE, as and to the extent reasonably
      requested by ACE, of the status of remedial efforts being undertaken with
      respect to such problem. IBM shall use diligent efforts to complete the
      Root Cause Analysis within fifteen (15) days. IBM may charge ACE for
      identifying, detailing and correcting failures of Service Levels to the
      extent such failures are caused by ACE, its agents, Affiliates or Eligible
      Recipients, or by actions taken by CIGNA at the Thornton Data Center.

7.4   Continuous Improvement Reviews

      During the six (6) month period commencing when the Service Levels have
      been established and at least annually thereafter, ACE and IBM shall
      review the Service Levels and the performance data collected and reported
      by IBM and shall: (i) to the extent required, add new Service Levels to
      permit further measurement or monitoring of the Services; (ii) modify or
      increase the Service Levels to reflect changes in the architecture,
      standards, strategies, needs or objectives defined by ACE; or (v) modify
      or increase the Service Levels to reflect agreed upon changes in the
      manner in which the Services are performed by IBM. As part of this review
      process, the Parties shall jointly determine and agree on additions to or
      modifications of the Service Levels and allocation of Service Level
      Credits to be specified in Schedule G.
                                 ----------

7.5   Measurement and Monitoring

      IBM shall implement measurement and monitoring tools and metrics as well
      as standard reporting procedures to measure and report IBM's performance
      of the Services against the applicable Service Levels. IBM shall provide
      ACE with read-only access to on-line change and problem management
      databases which shall be limited to ACE databases, in accordance with
      Schedule E, containing up-to-date information regarding the status of
      ----------
      service problems, service requests and user inquiries. IBM also shall
      provide ACE with information and access to the measurement and monitoring
      tools and procedures utilized by IBM for purposes of audit verification.
      ACE shall not be required to pay for such measurement and monitoring tools
      or the resource utilization associated with their use.

7.6   ACE Satisfaction Surveys

      Within three (3) months of the Commencement Date and at annual intervals
      thereafter, IBM and/or independent third parties engaged by IBM shall
      conduct the satisfaction surveys of ACE's management and End Users
      described in Schedule S in accordance with the survey protocols and
                   ----------
      procedures specified therein. To the extent IBM engages an independent
      third party to perform all or any part of any satisfaction survey, such
      third party shall be approved in advance by ACE. If the results of any
      satisfaction survey indicate that the level of satisfaction with IBM's
      performance is less than the target level specified in Schedule S, IBM
                                                             ----------
      shall promptly: (i) analyze and report on the root cause of the management
      or user dissatisfaction; (ii) develop an action plan to address and
      improve the level of satisfaction; (iii) present such plan to ACE for its
      review, comment and approval and (iv) take action in accordance with the
      approved plan and as necessary to improve the level of satisfaction. ACE
      and IBM shall establish a schedule for completion of the root cause
      analysis and the preparation and approval of the action plan which shall
      be reasonable and consistent with the severity and materiality of the
      problem; provided, that the time for completion of such tasks shall not
               --------
      exceed thirty (30) days from the date such user survey results are
      finalized and reported unless such tasks cannot be completed through use
      of continuous diligent efforts, in which case such tasks shall be
      completed as soon as possible. IBM's action plan developed hereunder shall
      specify the specific measures to be taken by IBM and the dates by
      which

                        Ace/IBM Proprietary Information
                                      24
<PAGE>

      each such action shall be completed. Following implementation of such
      action plan, IBM will conduct follow-up surveys with the affected ACE End
      Users and management to confirm that the cause of any dissatisfaction has
      been addressed and that the level of satisfaction has improved.

8.    PROJECT PERSONNEL

8.1   Transitioned Personnel

      (a)  IBM shall extend offers of employment to those ACE Personnel
           identified on Schedule M and shall waive any preconditions to such
                         ----------
           offers, including background checks, and/or drug testing. Such offers
           shall be for employment with IBM or a subcontractor in positions
           comparable to those held by such employees at ACE, and with initial
           base wages or salaries, variable compensation, and employee benefits
           in the aggregate, at least equal to that paid or provided by ACE as
           of the date of such offers. Unless otherwise specified in Schedule M
                                                                     ----------
           or agreed by the Parties, ACE employees accepting such offers shall
           be hired by IBM or a subcontractor effective as of the Commencement
           Date.

      (b)  With respect to any individual who is among the ACE Personnel
           identified on Schedule M who on the Commencement Date is in a leave
                         ----------
           status, including without limitation on medical, disability,
           industrial or sick leave, such employee shall remain an employee of
           ACE until the first day that such employee actually returns to work,
           with physician's release or other appropriate documentation stating
           that such employee may resume his or her prior work schedule, and
           upon such return shall be added to IBM's or a subcontractor's payroll
           system so long as such return date is within six (6) months after the
           Commencement Date. If such return date is not within such period,
           then IBM shall have no obligation to accept such employee as a
           Transitioned Employee hereunder.

      (c)  All ACE Personnel who accept IBM's offer of employment and begin work
           with IBM or a subcontractor pursuant to the foregoing paragraphs are
           herein referred to as "Transitioned Employees". Each such
                                  ----------------------
           Transitioned Employee's "Employment Effective Date" shall be the date
                                    -------------------------
           on which such employee is first added to IBM's payroll system.

      (d)  During the six (6) months following the Commencement Date, the
           Parties may agree upon, additional ACE Personnel to whom offers of
           employment are to be extended by IBM or a subcontractor. Such offers
           of employment shall be consistent with the provisions as set forth in
           this Article 8 and ACE Personnel accepting such offers shall be
                ---------
           treated as Transitioned Employees for all purposes.

      (e)  During the first twelve (12) months after the Employment Effective
           Date, neither IBM nor a subcontractor shall assign a Transitioned
           Employee, without ACE's prior written approval, to a work location
           other than the ACE Site at which he or she was employed prior to the
           Employment Effective Date or to the provision of services to a
           customer other than ACE.

      (f)  All Transitioned Employees will participate in IBM's or
           subcontractor's severance pay plan(s) on the same terms and
           conditions as similarly situated employees of IBM or subcontractor,
           as applicable. In determining benefits under IBM's and the
           subcontractor's severance program, for the period ending December 31,
           2001, IBM and the subcontractor shall provide CIGNA service credit to
           Transitioned Employees (thus, in determining the severance benefit,
           IBM and the subcontractor shall provide such Transitioned Employees
           with credit for combined CIGNA and IBM or subcontractor service time
           up to the CIGNA plan maximum of 52 weeks). In the event IBM or
           subcontractor terminates the employment of a Transitioned Employee
           prior to December 31, 2001 for any reason other than "cause" or
           "performance," ACE and IBM or a subcontractor shall share the cost of
           severance equally with IBM's total liability per employee limited to
           26 weeks of the then current

                        Ace/IBM Proprietary Information
                                      25
<PAGE>

           salary. For purposes of this Section 8.1(f), "cause" means the
                                        --------------   -----
           flagrant disregard of the rules and regulations of IBM,
           insubordination, negligence, misconduct, or commission of a felony.
           "Performance" means that the Transitioned Employee's level of
            -----------
           performance is at a level that would justify dismissal under the
           human resource policies of IBM and that after having completed a
           performance improvement program of at least 90 days, the level of
           performance has not improved sufficiently to avoid dismissal.

      (g)  During the six (6) months following the Commencement Date, ACE may
           designate, or the Parties may agree upon, one or more Transitioned
           Employees to whom ACE may extend offers of reemployment. Neither IBM
           nor a subcontractor shall interfere with ACE's efforts to reemploy
           any such Transitioned Employee.

8.2   Employee Benefit Plans

      (a)  General.  Except as otherwise provided in this Article 8, IBM shall
                                                          ---------
           offer to enroll the Transitioned Employee and his or her eligible
           dependents, effective as of the Transitioned Employee's Employment
           Effective Date, in the employee plans of IBM or a subcontractor that
           are made available to similarly situated employees of IBM or the
           subcontractor. IBM has listed all of such employee plans on Schedule
                                                                       --------
           M and provided ACE with true and complete copies of the most recent
           -
           summary plan descriptions and summary of material modifications for
           such employee plans or has provided a written summary where no
           current summary plan description exists. During the Term of this
           Agreement and any extension thereof, compensation and benefits
           provided by IBM or a subcontractor to the Transitioned Employees
           shall, in the aggregate, be no less favorable than the compensation
           and benefits generally available to IBM's or its subcontractor's
           employees.

      (b)  Years of Service Credit. In addition to service credited under
           Section 8.1(f) with respect to IBM's and subcontractor's severance
           program, the service of a Transitioned Employee prior to his
           Employment Effective Date, which is recognized by ACE or CIGNA, shall
           be recognized for purposes of vacation eligibility. If ACE wishes IBM
           or a subcontractor to recognize prior ACE or CIGNA service for
           vesting, and/or immediate participation, in the personal pension
           account, and/or immediate participation or opening account balances
           in the Future Health Account, IBM will price those options for ACE.

      (c)  Employee Welfare Benefit Plans. Each Transitioned Employee shall be
           eligible as of his or her Employment Effective Date to participate
           immediately in IBM's or a subcontractor's employee welfare benefit
           plans ("welfare plans"), provided that the Transitioned Employee
                   -------------
           enrolls in such plan within the time period established by IBM or
           subcontractor, which shall include medical care, hospitalization,
           life, accidental death and dismemberment, prescription drug, dental,
           short term disability and long term disability. Transitioned
           Employees and their beneficiaries who, as of the applicable
           Employment Effective Date, are undergoing a course of treatment or
           are hospitalized shall remain covered by the applicable ACE medical
           or dental plan until the earlier of the end of the course of
           treatment or hospitalization or the expiration of 60 days from the
           Employment Effective Date, provided that the 60 day period may be
           extended at the discretion of ACE. Subject to the general
           comparability requirements in Section 8.2(a), eligibility for, the
                                         -------------
           benefits of, and the amount, if any, of employee contributions toward
           welfare plan coverage will be determined by IBM or the subcontractor;
           provided, however, that each of IBM's welfare plans (except for
           optional Group Universal Life Insurance), shall (i) waive all pre-
           existing condition exceptions, exclusionary provisions and/or waiting
           periods for each such Transitioned Employee and any eligible spouse
           or

                        Ace/IBM Proprietary Information
                                      26
<PAGE>

           covered dependents, and (ii) grant credit for years of service in
           accordance with Section 8.2(b). In addition, medical deductibles paid
                           --------------
           in the calendar year of the Employment Effective Date by any
           Transitioned Employee shall be applied toward medical deductibles
           required by IBM's and subcontractor's group insurance program for the
           calendar year of the Employment Effective Date.

      (d)  Paid-Time-Off (Vacation/Sick Leave). Beginning on the Employment
           Effective Date, IBM shall make available to all Transitioned
           Employees paid-time-off benefits for vacation and absence from the
           workplace due to illness under its applicable plans, subject to and
           in accordance with the terms and conditions of such plans in effect
           from time to time, and shall recognize for purposes of accrual the
           years of service of such Transitioned Employees prior to their
           Employment Effective Dates determined in accordance with Section
                                                                    -------
           8.2(b). The paid-time-off benefits provided by IBM shall be no less
           ------
           favorable than those provided under the applicable ACE plan as of the
           Employment Effective Date and no less favorable than the vacation and
           absence from the workplace due to illness benefits generally
           available to IBM's employees. Vendor shall recognize vacation plans
           made by the Transitioned Employees and approved by ACE prior to the
           Employment Effective Date.

      (e)  Savings Plans.  IBM agrees to provide Transitioned Employees from
           their respective Employment Effective Dates with the opportunity to
           participate in a defined contribution plan which is qualified under
           Section 401(a) of the Code (the "IBM Savings Plan"), which complies
                                            ----------------
           with the requirements of Sections 8.2(a) and 8.2(b). IBM shall review
                                    --------------------------
           the plan documents for the Savings and Investment Plan of CIGNA and
           any other qualified defined contributions plan maintained by CIGNA in
           which any of the Transitioned Employees participated prior to the
           Commencement Date (collectively, "the defined contribution plans"),
           and any other documents related to the defined contribution plans
           that it deems relevant, to determine whether a trust-to-trust
           transfer of the account balances, or any portion of the account
           balances of the Transitioned Employees under the defined contribution
           plans from the trust funds maintained pursuant thereto to the trust
           fund maintained pursuant to the IBM Tax Deferred Savings Plan
           ("TDSP") would be consistent with the provisions and policies of
           TDSP. IBM shall notify ACE of its determination and, if applicable,
           shall specify the conditions that must be satisfied in advance of
           such transfer and the portion, if any, of the account balances of the
           Transitioned Employees that would not be included in such transfer.
           In the event that IBM notifies ACE and CIGNA that a trust-to-trust
           transfer of the account balances of the Transitioned Employees under
           one or more of the defined contribution plans, upon such conditions
           and subject to such exclusions as IBM may specify, would be
           consistent with the provisions and policies of TDSP, then ACE,
           together with CIGNA, shall determine whether any of the defined
           contribution plans will undertake such a transfer and, if so, whether
           the Transitioned Employees will be given the opportunity to make an
           election as to whether their account balance under such defined
           contribution plan, or any portion thereof, will be included in the
           transfer. In the event that IBM and ACE agree to a trust-to-trust
           transfer from one of the defined contributions plans to TDSP, then
           the parties shall use commercially reasonable efforts to cause such a
           transfer to take place within 120 days of the hire date for the
           Transitioned Employees. It is expressly understood that neither IBM
           nor ACE (with CIGNA) shall have an obligation to agree to a transfer
           of assets from the trust fund maintained pursuant to any of the
           defined contribution plans to the trust fund maintained pursuant to
           TDSP or to a rollover of account balances to the TDSP, if either
           party determines in good faith and it its sole discretion that such a
           transfer would be unduly burdensome, or could jeopardize the tax
           qualified status of its plan, or would otherwise be inconsistent with
           applicable legal and regulatory requirements.

      (f)  Reimbursement Account Plans. As of the Effective Date, IBM shall

      (g)  Tuition Assistance. Transitioned Employees shall be eligible to
           participate in all tuition assistance programs provided by IBM to its
           similarly situated employees. Courses which are in progress as of the
           enrolled Transitioned Employee's Employment Effective Date and for
           which tuition assistance has been approved by ACE, and courses which
           have been approved by ACE and paid for by the Transitioned Employee
           prior to the Employment Effective Date shall be reimbursed by IBM at
           the completion of the course, provided all of the requisites for
           reimbursement under the ACE program have been approved. "Course"
                                                                    ------
           refers to specific classes in progress or scheduled to start during a
           particular term and does not refer to a degree program. IBM's
           obligation to reimburse for the Courses is limited to those employees
           and Courses which were previously identified prior to the
           Commencement Date.

      (h)  Bonus Programs. IBM shall provide to the Transitioned Employees bonus
           programs no less favorable than the bonus programs available to
           similarly situated employees of IBM.

      (i)  Retiree Medical. Transitioned Employees will participate in IBM's or
           subcontractor's retiree medical benefit plan(s) on the same terms and
           conditions as similarly situated employees of IBM or subcontractor.

      (j)  Restricted Stock. ACE may, in its discretion, grant awards of
           restricted stock to individuals who become Transitioned Employees.
           Any such grant shall be effective as of a date on or before the date
           the Transitioned Employee becomes an employee of IBM or a
           subcontractor. In ACE's discretion, any such grant may provide that
           the Transitioned Employee's right to vest in such award or awards
           will be dependent on continued employment with IBM or a subcontractor
           for a specified period, and the identity of the Transitioned
           Employees holding such awards shall be provided to IBM by ACE. IBM
           shall notify ACE, not less frequently than quarterly, of the
           employment status and other information that ACE reasonably requires
           with respect to such individuals to determine the vesting status of
           such awards (or otherwise to administer the awards).

8.3   Other Employee Matters

      IBM shall be responsible for funding and distributing benefits under the
      benefit plans in which Transitioned Employees participate on or after the
      Employment Effective Date and for paying any compensation and remitting
      any income, disability, withholding and other employment taxes for such
      Transitioned Employees beginning on the Employment Effective Date. Unless
      otherwise agreed, ACE shall be responsible for funding and distributing
      benefits under the ACE benefit plans in which Transitioned Employees
      participated prior to the Employment Effective Date and for paying any
      compensation and remitting any income, disability, withholding and other
      employment taxes for such Transitioned Employees for the period prior to
      the Employment Effective Date. ACE shall provide IBM with information in
      ACE's possession reasonably required by IBM to fulfill its obligations
      under this Article 8.

      (a)  Approval of Key IBM Personnel

           (i)  Before assigning an individual to act as one of the Key IBM
                Personnel whether as an initial assignment or a subsequent
                assignment, IBM shall notify ACE of the proposed assignment,
                shall introduce the individual to appropriate ACE
                representatives, shall provide reasonable opportunity for ACE
                representatives to interview the individual, and shall provide

                 by ACE. If ACE in good faith objects to the proposed assignment
                 for a specified lawful reason, the Parties shall attempt to
                 resolve ACE's concerns on a mutually agreeable basis. If the
                 Parties have not been able to resolve ACE's concerns within ten
                 (10) business days, IBM shall not assign the individual to that
                 position and shall propose to ACE the assignment of another
                 individual of suitable ability and qualifications.

           (ii)  The Key IBM Personnel that have been approved as of the
                 Effective Date are listed in Schedule C.

           full time and effort for the period specified in Schedule C to the
                                                            ----------
           provision of the Services under this Agreement. IBM shall not
           transfer, reassign or remove any of the Key IBM Personnel (except
           where the Key Personnel (i) voluntarily resigns from IBM, (ii) is
           dismissed by IBM for violations of conditions of employment (e.g.,
           fraud, drug abuse, theft), (iii) fails to perform his or her duties
           and responsibilities pursuant to this Agreement in IBM's reasonable
           judgment or (iv) dies or is unable to work due to his or her
           disability) or announce its intention to do so during the specified
           period without ACE's prior approval, which approval shall not be
           unreasonably withheld. IBM shall transfer, reassign or remove one of
           its Key IBM Personnel only after (i) giving ACE at least ninety (90)
           days prior written notice of such action, and (ii) complying with the
           requirement of Article 8.4(a)(i) above.

           or death) without ACE's prior approval, which ACE may not
           unreasonably withhold.

8.5   IBM Project Executive

      IBM shall designate a "IBM Project Executive" for ACE. Each IBM Project
                             ---------------------

      have day-to-day authority for ensuring customer satisfaction and achieving
      attainment of all Service Levels and Performance Standards.

8.6   IBM Personnel Are Not ACE Employees

      Except as otherwise expressly set forth in this Agreement, the Parties
      intend to create an independent contractor relationship and nothing in
      this Agreement shall operate or be construed as making ACE or IBM
      partners, joint venturers, principals, agents or employees of the other.
      No officer, director, employee, agent, Affiliate, contractor or
      subcontractor retained by IBM to perform work on ACE's behalf hereunder
      shall be deemed to be an officer, director, employee, agent, Affiliate,
      contractor or subcontractor of ACE. IBM, not ACE, has the right, power,
      authority and duty to supervise and direct the activities of the IBM
      Personnel and to compensate such IBM Personnel for any work performed by
      them on ACE's behalf pursuant to this Agreement.

8.7   Replacement, Qualifications, and Retention of IBM Personnel

      (a)  IBM shall assign sufficient IBM personnel (including Subcontractors)
           to provide the Services in accordance with this Agreement and such
           IBM personnel shall possess suitable competence, ability and
           qualifications and shall be properly educated and trained for the
           Services they are to perform.

      (b)  In the event that ACE determines reasonably, lawfully and in good
           faith that the continued assignment to ACE of any IBM personnel
           (including Key IBM Personnel and IBM Subcontractors) is not in the
           best interests of ACE, then ACE shall give IBM written notice to that
           effect specifying the reason for its position and requesting that
           such IBM Personnel be replaced. Promptly after its receipt of such a
           request by ACE, IBM shall investigate the matters stated in the
           request and discuss its findings with ACE. If IBM determines that
           ACE's request is reasonable, lawful and in good faith, IBM shall take
           appropriate action. If requested to do so by ACE, IBM shall
           immediately remove the individual in question from all ACE Sites
           pending completion of IBM's investigation and discussions with ACE.
           If, following discussions with IBM, ACE still in good faith requests
           replacement of such IBM Personnel, IBM shall promptly replace such
           IBM Personnel with an individual of suitable ability and
           qualifications. Nothing in this provision shall operate or be
           construed to limit IBM's responsibility for the acts or omission of
           the IBM Personnel.

      (c)  If ACE determines that IBM's turnover rate is excessive and so
           notifies IBM, IBM shall provide reasonable data concerning its
           turnover rate and shall meet with ACE to discuss the reasons for the
           turnover rate. IBM shall submit to ACE for its approval a proposal
           for reducing the turnover rate to an acceptable level.
           Notwithstanding any transfer or turnover of IBM Personnel, IBM shall
           remain obligated to perform the Services without degradation and in
           accordance with the Performance Standards.

8.8   Training/Career Opportunities

      IBM shall offer training, skills development and career growth
      opportunities to Transitioned Employees that are at least as favorable as
      those offered generally to employees of similar rank and position.

8.9   Conduct of IBM Personnel

      (a)  While at the ACE Sites, IBM Personnel shall (i) comply with the rules
           and regulations that ACE or the Eligible Recipients sets regarding
           personal and professional conduct, safety and security practices and
           procedures of which ACE provides notice (including compliance with
           ACE's dress code, the wearing of an identification badge provided by
           ACE, and adherence to ACE's regulations and general safety practices
           and procedures) generally applicable to such ACE Facilities and (ii)
           otherwise conduct themselves in a businesslike manner.

      (b)  At all times during this Agreement, all IBM Personnel shall clearly
           identify themselves as IBM Personnel and not employees of ACE. This
           shall include any and all communications, oral, written or
           electronic. Each of the IBM Personnel shall wear a badge provided by
           ACE indicating that he or she is not an employee of ACE. It is the
           responsibility of IBM and the IBM Personnel to avoid any confusion
           regarding whether the IBM Personnel are employees of ACE.

      IBM agrees to immediately remove any IBM Personnel who engage in substance
      abuse while on ACE Facilities, in a ACE vehicle or while performing
      Services. Substance abuse includes the sale, attempted sale, possession or
      use of illegal drugs, drug paraphernalia, or alcohol, or the misuse of

           to reflect changes in the operations or procedures described therein,
           and shall provide the proposed changes in the manual to ACE for

      in providing the Services, and shall work with ACE to prevent or
      circumvent such problem or delay. IBM shall be relieved of Service Levels
      to the extent of such delay. IBM will coordinate with ACE and the ACE
      Third Party Contractors to resolve differences and conflicts arising
      between the Services and other activities undertaken by ACE or any of the

           addition, upon ACE request, IBM shall record and promptly distribute
           minutes for every meeting.

      (c)  IBM shall notify the ACE Project Executive in advance of scheduled
           meetings with End Users or Eligible Recipients (other than meetings
           pertaining to the provision of specific Services on a day-to-day
           basis) and shall invite the ACE Project Executive to attend such
           meetings or to designate a representative to do so.

<PAGE>

      (b)  If IBM desires to make a System Change, IBM shall provide reasonable
           notice to ACE and coordinate such change with ACE To the extent
           initiated by IBM solely for its own benefit, IBM shall bear all
           charges, fees and costs associated with such System Change, including
           all charges, fees and costs associated with (i) the design,
           installation, implementation, testing and rollout of such System
           Change, (ii) any modification or enhancement to, or substitution for,
           any impacted Software or Equipment, (iii) any increase in the cost of
           operating, maintaining or supporting any impacted system, Software or
           Equipment, and (iv) any increase in resource usage.

      (c)  IBM shall make no System Change which (i) may increase ACE's total
           cost of receiving the Services; (ii) may require material changes to
           ACE facilities, systems, software or equipment; or (iii) may
           materially and adversely impact the functionality, interoperability,
           performance or resource efficiency of the Services, without first
           obtaining ACE's approval, which approval ACE may withhold in its sole
           discretion. If IBM desires to make such a System Change, it shall
           provide to ACE a written proposal describing in detail the extent to
           which the desired System Change may affect the functionality,
           performance or resource efficiency of the Services and the benefits,
           savings and risks to ACE associated with such System Change.

      (d)  IBM shall make no System Change that may require ACE to install a new
           version, release or upgrade of, or replacement for, any Software or
           Equipment or to modify any Software or Equipment without first
           obtaining ACE's approval, which approval ACE may withhold in its sole
           discretion.

      (e)  Notwithstanding the foregoing, IBM may make temporary System Changes
           required by an emergency if it has been unable to contact the ACE
           Project Executive to obtain approval after making reasonable efforts.
           IBM shall document and report such emergency changes to ACE not later
           than the next business day after the change is made.

      (f)  IBM will schedule and implement all System Changes so as not to (i)
           materially and unnecessarily disrupt or adversely impact the business
           or operations of ACE or the Eligible Recipients, (ii) materially
           degrade the Services then being received by them, or (iii) interfere
           with their ability to obtain the full benefit of the Services.

      (g)  On a monthly basis, IBM will prepare a rolling quarterly "look ahead"
           schedule for ongoing and planned System Changes for the next three
           (3) months. The status of System Changes will be monitored and
           tracked against the applicable schedule.

      (h)  For any System Change, IBM shall, upon ACE's request, perform a
           comparison at a reasonable and mutually agreed level of detail,
           between the amount of resources required by the affected Software or
           Equipment to perform a representative sample of the processing being
           performed for ACE immediately prior to the System Change and
           immediately after the System Change. ACE shall not be required to pay
           for increased resource usage due to a System Change for a Steady
           State Operation except to the extent that such System Change is
           requested by ACE with notice of the increased usage or changes in ACE
           usage based on additional or changed functionality.

9.8   Software Currency

      (a)  Currency of Software.  Subject to and in accordance with Sections
                                                                    --------
           6.2, 9.6, 9.7 and 9.8(b), IBM agrees to maintain reasonable currency
           ------------------------
           for Software for which IBM is financially, operationally and
           administratively responsible and to provide help desk and other
           support for new releases and versions of such Software. For purposes
           of this Section, "reasonable currency" shall mean that, unless
                             -------------------

                        Ace/IBM Proprietary Information
                                      35
<PAGE>

           otherwise directed by ACE, IBM shall maintain Software within one
           Major Release of the then current Major Release and shall do so
           within twelve (12) months of such then current Major Release becoming
           publicly available. "Reasonable currency" also shall mean that,
                                -------------------
           unless otherwise directed by ACE, IBM shall promptly install Minor
           Releases as they become publicly available. Prior to installing a new
           Major Release or Minor Release, IBM shall evaluate and test such
           Release to verify that it will perform in accordance with the
           specifications and the architectures and standards established by ACE
           and that it will not without ACE's prior approval (i) increase ACE's
           total cost of receiving the Services; (ii) require material changes
           to ACE facilities, systems, software or equipment; or (iii)
           materially and adversely impact the functionality, interoperability,
           performance or resource efficiency of the Services. Notwithstanding
           Sections 9.7 (c), IBM shall confer with ACE prior to installing any
           ----------------
           Major Release or Minor Release, shall provide ACE with the results of
           its testing and evaluation of such Release and shall not install such
           Release if directed not to do so by ACE, notwithstanding, in the
           event that ACE directs IBM not to install such Release, IBM will
           continue to support the currently installed version of the Software
           provided that the manufacturer of the such installed version
           continues to provide a standard maintenance offering for such
           installed version. If ACE requires IBM to use a Major Release or
           Minor Release for which maintenance offerings are not available and
           for which source code is not available, IBM shall be relieved of
           Service Levels to the extent that failure to achieve such Service
           Levels is caused by such Major Release or Minor Release.

      (b)  Applications Software. ACE and the Eligible Recipients shall maintain
           Software currency for Applications Software or other Software for
           which ACE is financially responsible under this Agreement. Subject to
           9.8(a), IBM shall not install new Software releases or make other
           Software changes if doing so would require ACE or the Eligible
           Recipients to install new releases of, replace, or make other changes
           to Applications Software or other Software for which ACE is
           financially responsible unless ACE consents in writing to such
           change.

9.9   Year 2000 Compliance

      (a)  General. "Year 2000 Compliant" or "Year 2000 Compliance" means that a
                     -------------------      --------------------
           product, when used in accordance with its associated documentation,
           is capable of correctly processing, providing and/or receiving date
           data within and between the twentieth and twenty-first centuries,
           provided that all products (for example, hardware, software and
           firmware) used with such product properly exchanges accurate date
           data with it.

      (b)  Year 2000 Coordination. IBM shall reasonably cooperate with ACE in
           the execution of the "ACE Group Year 2000 Compliance Guidelines"
           dated April 17, 1998, to the extent such cooperation is reasonably
           related to IBM's performance of the Services and to the extent
           consistent with the terms and conditions of this Agreement.

      (c)  Emergency Access to Year 2000 Services, Personnel and Resources. Upon
           ACE's request and subject to availability of resources, IBM shall
           provide ACE with access to those IBM services, personnel and
           resources required to respond on an emergency basis to Year 2000
           Compliance problems. The Parties acknowledge that the provision of
           such services, personnel and resources, in addition to the assigned
           personnel and resources, constitutes a New Service for which IBM may
           be entitled to additional compensation.

      (d)  IBM Procurement Responsibilities. IBM shall obtain assurances of Year
           2000 Compliance from each third party vendor from whom IBM procures

                 (3)  IBM Products not provided and selected by IBM under the
                      Agreement, ((1), (2), and (3), collectively, "Other
                                                                    -----
                      Products") to correctly process or properly exchange
                      --------
                      accurate date data.

           (iii) IBM will be relieved of its obligations under the Agreement
                 (including meeting Service Levels) due to the inability of such
                 Other Products to correctly process or properly exchange
                 accurate date data.

           (iv)  ACE acknowledges that it is responsible for assessing its
                 current systems and taking appropriate action to migrate to
                 year 2000-ready systems.

      Upon ACE's request and subject to availability of resources, IBM shall
      promptly provide ACE with equal access to IBM's specialized technical
      services, personnel and resources (the "Specialized Services"). The
                                              --------------------
      Parties intend that ACE shall receive such Specialized Services in a
      reasonable period of time after an appropriate work authorization has been
      signed by both Parties. The Parties acknowledge that the provision of such
      Specialized Services may, in some cases, constitute New Services for which
      IBM is entitled to additional compensation, but in no event will IBM
      perform, or be entitled to any additional compensation for, such
      Specialized Services, unless a New Services work authorization has been
      signed by both Parties.

9.11  Audit Rights

      (a)  IBM Records. IBM shall maintain and provide access upon request to
           the portion of records, documents and other information required to
           meet ACE's audit rights under this Agreement ("IBM Records"). IBM

           requested by ACE or its designee in conducting any such audit,
           including installing and operating audit software.

      (c)  Financial Audits. Upon reasonable notice from ACE, and subject to IBM
           or IBM agents' security requirements and execution of IBM's standard
           Confidentiality Agreements, IBM shall, and shall cause its
           Subcontractors and suppliers to, provide to ACE (and internal and
           external auditors, inspectors, regulators and other representatives
           that ACE may designate from time to time) access at reasonable hours
           to IBM Personnel and to IBM Records and other pertinent information,
           all to the extent relevant to the performance of IBM's financial
           obligations under this Agreement. Such access shall be provided for
           the sole purpose of performing audits and inspections relating to the
           Services to verify the accuracy of IBM's Charges to see that IBM is
           exercising reasonable procedures to control the resources provided by
           IBM to ACE, and that the Services are being provided in accordance
           with the Service Levels. IBM shall provide any assistance reasonably
           requested by ACE or its designee in conducting any such audit and
           shall make requested personnel, records and information available
           during the Term and thereafter, during the period specified in IBM's
           records retention policy, as it may be reasonably adjusted from time

           IBM, and IBM or ACE, as applicable, does not successfully dispute the
           amount questioned by such audit, IBM or ACE, as applicable, shall
           promptly pay to the other Party the amount of such overcharge or
           undercharge as the case may be, together with interest at the rate
           specified in Section 12.2.
                        ------------

      (d)  General Procedures.

           (i)   ACE shall not be given access to the proprietary information of
                 other IBM customers or to IBM locations that are not related to
                 ACE or the Services or to information that is not reasonably
                 necessary to perform the audit.

           (ii)  In performing audits, ACE shall endeavor to avoid unnecessary
                 disruption of IBM's operations and unnecessary interference
                 with IBM's ability to perform the Services in accordance with

                 operations or interferes with IBM's ability to perform the
                 Services, IBM shall be relieved of Service Levels.

           (iii) Following any audit, ACE shall conduct (in the case of an
                 internal audit), or request its external auditors or examiners
                 to conduct, an exit conference with IBM to obtain factual
                 concurrence with issues identified in the review.

           (iv)  Access by ACE shall not be requested more than once each
                 calendar year unless required by Law or regulatory agencies and
                 IBM shall be given 72 hour written notice prior to such access.

           (v)   ACE shall use reasonable efforts to conduct the audit
                 efficiently and expeditiously and at reasonable business hours.

      (e)  IBM Response. IBM and ACE shall meet to review each audit report
           promptly after the issuance thereof. IBM will respond to each audit
           report in writing within thirty (30) days from receipt of such
           report, unless a shorter response time is specified in such report.
           IBM and ACE shall develop and agree upon an action plan to promptly
           address and resolve any deficiencies, concerns and/or recommendations
           in such audit report and IBM, at its own expense, shall undertake
           remedial action in accordance with such action plan and the dates
           specified therein.

      (f)  Response to Government Audits. If an audit by a governmental body or
           regulatory authority having jurisdiction over ACE, an Eligible
           Recipient or IBM results in a finding that IBM or ACE is not in
           compliance with any generally accepted accounting principle or, with
           respect to the following that are either ordinary course of business
           for property casualty insurance companies or of which ACE provides to
           IBM prior written notice, other audit requirement or any rule,
           regulation or law relating to the performance of its obligations
           under this Agreement, IBM or ACE, as the case may be, shall, at its
           own expense and within the time period specified by such auditor,
           address and resolve the deficiency(ies) identified by such
           governmental body or regulatory authority. The Parties believe such
           other audit requirements, rules, regulations and laws that are not
           ordinary course of business for property casualty insurance companies
           are prohibitions, and the Parties do not intend that IBM will be
           required to make substantial expenditures to comply with the same.

      (g)  Audit Costs. IBM and its Subcontractors and suppliers shall provide
           the Services described in this Section 9.11 at no additional charge
                                          ------------
           to ACE, to the extent that the audit occurs in the ordinary course of
           business (e.g., periodic, regular regulatory audits).

9.12  Agency and Disbursements

      (a)  Disbursements. Beginning on the Commencement Date, IBM shall make
           payments to those certain agreed upon lessors, licensors and vendors
           specified in Schedule F as paying agent of ACE or the Eligible
                        ----------
           Recipients, or shall reimburse ACE for payments made by ACE or the
           Eligible Recipients to such lessors, licensors and vendors.

      (b)  Limited Agency. ACE hereby appoints IBM as its limited agent during
           the Term solely for the purposes of the administration of and payment
           of Pass-Through Expenses and amounts for which IBM is responsible
           under Third Party Contracts, Equipment Leases and Third Party
           Software licenses. ACE shall provide, on a timely basis, such
           affirmation of IBM's authority to such lessors, licensors, vendors,
           and other third parties as IBM may reasonably request.

                        Ace/IBM Proprietary Information
                                      39
<PAGE>

      (c)   Reimbursement for Substitute Payment. If either Party in error pays
            to a third party an amount for which the other Party is responsible
            under this Agreement, the Party that is responsible for such payment
            shall reimburse the paying Party for such amount.

      (d)   Notice of Decommissioning. IBM agrees to notify ACE as soon as
            reasonably possible when IBM determines that it will no longer use
            to provide the Services any ACE Owned Equipment or ACE leased
            Equipment. Notification will be in writing and include the
            identification of the Equipment, and the date it will no longer be
            needed by IBM. Upon receipt of any such notice, ACE may (or may
            cause the applicable Eligible Recipient to), in its sole discretion,
            terminate the Equipment Lease for such leased Equipment as of the
            date specified in such notice and sell or otherwise dispose of or
            redeploy such ACE Owned Equipment that is the subject of such a
            notice as of the date specified in such notice. Upon IBM ceasing to
            use any Equipment (or, in the case of leased Equipment, upon the
            last day ACE is obligated to make such leased Equipment available to
            IBM, if earlier), IBM shall return the same to ACE in condition at
            least as good as the condition thereof on the Commencement Date,
            ordinary wear and tear excepted..

9.13  Subcontractors

      (a)   Use of Subcontractors. IBM shall not subcontract any of its material
            responsibilities without ACE's prior written approval.
            Notwithstanding the forgoing, IBM's use in the ordinary course of
            business of third party services or products that are not dedicated
            to ACE, that are not material to any particular function
            constituting a part of the Services, that do not result in a
            material change in the way IBM conducts its business or that do not
            make any work product specifically for ACE, shall not constitute a
            delegation or subcontracting of IBM's responsibilities covered by
            this Section 9.13. A list of pre-approved subcontractors is set
                 ------------
            forth in Schedule D. Prior to entering into a subcontract with a
                     ----------
            third party for the Services, IBM shall (i) give ACE reasonable
            prior written notice specifying the components of the Services
            affected, the scope of the proposed subcontract, the identity and
            qualifications of the proposed Subcontractor.

      (b)   IBM Responsibility for Subcontractors. IBM shall remain responsible
            for obligations performed by Subcontractors and the conduct of
            Subcontractor personnel to the same extent as if such obligations
            were performed by IBM's employees. IBM shall be ACE's sole point of
            contact regarding the Services, including with respect to payment.

10.   ACE RESPONSIBILITIES

10.1  Responsibilities

      In addition to ACE's responsibilities as expressly set forth elsewhere in
      this Agreement, ACE shall be responsible for the following:

      (a)   ACE shall designate, prior to commencement of the Services by IBM,
            one individual to whom all IBM communications concerning this
            Agreement may be addressed (the "ACE Project Executive"), who shall
                                             ---------------------
            have the authority to act on behalf of ACE in all day-to-day matters
            pertaining to this Agreement. ACE may change the designated ACE
            Project Executive from time to time by providing notice to IBM.
            Additionally, ACE will have the option, but will not be obligated,
            to designate additional representatives who will be authorized to
            make certain decisions (e.g., regarding emergency maintenance) if
            the ACE Project Executive is not available.

                        Ace/IBM Proprietary Information
                                      40
<PAGE>

      (b)   ACE shall cooperate with IBM by, among other things, making
            available, as reasonably requested by IBM, management decisions,
            information, approvals and acceptances so that IBM may accomplish
            its obligations and responsibilities hereunder.

10.2  Savings Clause

      IBM's failure to perform its responsibilities under this Agreement or to
      meet the Service Levels shall be excused if and to the extent such IBM
      non-performance results from ACE's, ACE's agents', ACE's Affiliates',
      Eligible Recipients' or CIGNA's wrongful actions or failure to perform any
      of their respective responsibilities. IBM shall provide ACE with
      reasonable notice in writing of any such non-performance and IBM shall use
      commercially reasonable efforts to perform notwithstanding such wrongful
      actions or any such failures to perform. ACE also agrees to reimburse IBM
      for any reasonable additional costs, charges and expenses incurred as a
      result of such delay and ACE shall pay IBM the full amounts of all
      undisputed Charges set forth herein.

11.   CHARGES
11.1  General

      (a)   In consideration of IBM's performance of the Services, ACE agrees to
            pay IBM the applicable Charges set forth in Schedule J.
                                                        ----------

      (b)   The charges for Transition Services, as set forth in Schedule J,
                                                                 ----------
            from ACE to IBM provided by or for IBM under this Agreement are
            included in the Charges set forth in Schedule J and there are no
                                                 ----------
            separate or additional charges for such Transition Services.

      (c)   Except as agreed to in writing by the Parties, ACE shall not pay any
            amounts for the Services or Transition Service from ACE to IBM in
            addition to those set forth in this Article 11 or Schedule J or
                                                ----------    ----------
            elsewhere in this Agreement. Any costs incurred by IBM prior to the
            Commencement Date are included in the Charges set forth in Schedule
                                                                       --------
            J and are not to be separately paid or reimbursed by ACE.
            -

      (d)   IBM shall reperform, at no additional expense to ACE, any Services
            that result in incorrect outputs to the extent caused by an error or
            breach by IBM, and the resources required for such performance shall
            not be counted in calculating the Charges payable or resources
            utilized by ACE hereunder.

11.2  Retained and Pass-Through Expenses

      (a)   ACE shall retain and pay all Retained Expenses directly to the
            applicable vendors.

      (b)   As part of the Services, IBM shall pay all Pass-Through Expenses
            directly to the applicable suppliers and shall invoice ACE for
            amounts paid to such suppliers. Before paying an invoice for any
            Pass-Through Expense, IBM shall review and validate the invoiced
            charges, identify and correct any errors or omissions and resolve
            any questions or changes with the applicable supplier. IBM shall
            deliver to ACE the original supplier invoice, together with any
            documentation supporting such invoice and a statement that IBM has
            reviewed and validated the invoiced charges, prior to or in
            connection with the IBM invoice containing such Pass-Through
            Expense. To the extent IBM fails to comply with its obligations
            hereunder, it shall be financially responsible for any discounts
            lost or any late fees, interest charges or other costs or expenses
            incurred by ACE.

                        Ace/IBM Proprietary Information
                                       41
<PAGE>

      (c)   All Retained Expenses and Pass-Through Expenses as of the Effective
            Date are set forth on Schedule J. No new Retained Expenses may be
                                  ----------
            added without ACE's prior written consent, which it may withhold in
            its sole discretion. ACE may agree to add Retained Expenses and
            Pass-Through Expenses to Schedule J and may re-designate a Retained
                                     ----------
            Expense as a Pass-Through Expense with IBM's consent, which consent
            shall not be withheld unreasonably.

      (d)   IBM will continually seek to identify methods of reducing and
            minimizing ACE's Retained and Pass-Through Expenses and will notify
            ACE of such methods and the estimated potential savings associated
            with each such method.

11.3  Incidental Expenses

      IBM acknowledges that, except as expressly provided otherwise in the
      Agreement, expenses that IBM incurs in performing the Services are
      included in IBM's charges and rates set forth in this Agreement.
      Accordingly, such IBM expenses are not separately reimbursable by ACE
      unless ACE has agreed in advance and in writing to reimburse IBM for the
      expense

11.4  Taxes

      The Parties' respective responsibilities for taxes arising under or in
      connection with this Agreement shall be as follows:

      (a)   Each Party shall be responsible for any franchise or privilege taxes
            on its business and for any taxes based on its net income or gross
            receipts.

      (b)   Each Party shall be responsible for any sales, lease, use, personal
            property or other such taxes on Equipment, Software or property it
            owns or leases from a third party and/or for which it is financially
            responsible under Schedule F of this Agreement.
                              ----------

      (c)   IBM shall be responsible for all sales, service, value-added, lease,
            use, personal property, excise, consumption, and other taxes and
            duties payable by IBM on any goods or services acquired and used or
            consumed by IBM in providing the Services where the tax is imposed
            on IBM's acquisition or use of such goods or services.

      (d)   ACE shall be responsible for all sales, use, excise, value added,
            consumption, service or other taxes assessed on the receipt of the
            Services as a whole, or on any particular Service received by ACE or
            the Eligible Recipients from IBM.

      (e)   The Parties agree to cooperate fully with each other to enable each
            to more accurately determine its own tax liability and to minimize
            such liability to the extent legally permissible. IBM's invoices
            shall separately state the Charges that are subject to taxation and
            the amount of taxes included therein. Each Party will provide and
            make available to the other any resale certificates, information
            regarding out-of-state or out-of-country sales or use of equipment,
            materials, or services, and other exemption certificates or
            information reasonably requested by either Party.

      (f)   Each Party will promptly notify the other of, and reasonably
            coordinate with the other, the response to and settlement of, any
            claim for taxes asserted by applicable taxing authorities for which
            the other Party is responsible hereunder. With respect to any claim
            arising out of a form or return signed by a Party to this Agreement,
            such Party will have the right to elect to control the response to
            and

                        Ace/IBM Proprietary Information
                                       42
<PAGE>

            settlement of the claim, but the other Party will have all rights to
            participate in the responses and settlements that are appropriate to
            its potential responsibilities or liabilities. If either Party
            requests the other to challenge the imposition of any tax, the
            requesting Party will reimburse the other for the reasonable legal
            fees and expenses it incurs. A Party will be entitled to a
            proportional share of any tax refunds or rebates granted to the
            extent such refunds or rebates are of taxes that were paid by it.

      (g)   Each Party represents, warrants and covenants that it will file
            appropriate tax returns, and pay applicable taxes owed arising from
            or related to the Services in applicable jurisdictions.

11.5  New Services

      (a)   If ACE requests that IBM perform any New Services, IBM shall
            promptly prepare a New Services proposal for ACE's consideration.
            Unless otherwise agreed by the Parties, IBM shall prepare such New
            Services proposal at no additional charge to ACE and shall deliver
            such proposal to ACE within fourteen (14) days of its receipt of
            ACE's request. Such New Services proposal shall include, among other
            things, (i) a project plan and fixed price or cost estimate for the
            New Service; (ii) a breakdown of the cost buildup for such pricing
            or estimate, (iii) a description of the service levels to be
            associated with such New Service; (iv) a schedule for commencing and
            completing the New Service; (v) a description of any new hardware or
            software to be provided by IBM in connection with the New Service;
            (vi) a description of any software and hardware resources and
            runtime requirements necessary to provide the New Service; and (vii)
            the human resources necessary to provide the New Service. ACE may
            accept or reject any New Services proposal in its sole discretion.
            If ACE accepts IBM's proposal and IBM agrees to provide the New
            Services, IBM will perform the New Services in accordance with the
            provisions set forth herein and therein, and will be paid in
            accordance with the proposal submitted by IBM and the provisions of
            this Agreement. At such time, the scope of the Services will be
            expanded to include such New Services unless the Parties agree in
            writing to the contrary. The Parties shall agree in writing as to
            whether New Services are Exclusive Services or Non-Exclusive
            Services. Notwithstanding any provision to the contrary, the pricing
            proposed by IBM shall take into account the existing and future
            volume of business between ACE and IBM.

      (b)   ACE may elect to solicit and receive bids from third parties to
            perform any New Services. If ACE elects to use third parties to
            perform New Services, (i) such New Services shall not be deemed
            Services under the provisions of this Agreement and (ii) IBM shall
            reasonably cooperate with such third parties as provided in Section
                                                                        -------
            9.2 to the extent such cooperation does not impact IBM's ability to
            ---
            provide the Services. ACE shall reimburse IBM for reasonable costs
            of complying with this Section 11.5(b).
                                   ---------------

      (c)   The Parties anticipate that the Services will evolve and be
            supplemented, modified, enhanced or replaced over time to keep pace
            with technological advancements and improvements in the methods of
            delivering services, and the Parties acknowledge that these
            evolutionary changes may modify the "Services" and will not
            necessarily be deemed to result in New Services.

      (d)   IBM will promptly inform the ACE Project Executive of requests for
            New Services from End Users or Eligible Recipients, and shall submit
            any proposals for New Services to the ACE Project Executive or his
            or her designee. IBM shall not agree to provide New Services to any
            End Users or Eligible Recipients without the prior written approval
            of the ACE Project Executive or his or her designee.

      (e)   If ACE requests that IBM provide Services to Entities other than
            Eligible Recipients, the requested Services shall be treated as New
            Services. Unless otherwise agreed by the Parties, such Services
            shall

                        Ace/IBM Proprietary Information
                                       43
<PAGE>

            be performed in accordance with the terms and conditions governing
            the provision of the same Services to existing Eligible Recipients;
            provided, however, that to the extent Services are to be provided
            outside the United States, the Parties may modify or add necessary
            terms and conditions.

11.6  Extraordinary Events

      (a)   As used in this Agreement, an "Extraordinary Event" shall mean a
                                           -------------------
            circumstance in which an event or discrete set of events has
            occurred or is planned with respect to the business of ACE that
            results or will result in a change in the scope, nature or volume of
            the Services that ACE will require from IBM, and which is expected
            to cause the estimated average aggregate monthly amount of
            chargeable resource used to provide the Services to increase or
            decrease by twenty percent (20%) or more. Examples of the kinds of
            events that might cause such substantial increases or decreases
            include:
            (1)    changes in locations where ACE operates;

            (2)    changes in products of, or in markets served by, ACE;

            (3)    mergers, acquisitions or divestitures of ACE;

            (4)    changes in the method of service delivery, excluding delivery
                   of the Services by ACE or its Eligible Recipients or by any
                   provider other than IBM;

            (5)    changes in market priorities; or

            (6)    changes in the number of business units being serviced by IBM
                   that were not anticipated as of the Effective Date.


      (b)   If an Extraordinary Event occurs, ACE may, at its option, request a
            reduction in the unit charges specified in Schedule J in accordance
                                                       ----------
            with the following:

            (1)    As appropriate, IBM and ACE shall mutually determine on a
                   reasonable basis the resulting efficiencies and economies
                   and/or the resources no longer required by IBM to provide the
                   Services ("Targeted Resource Reductions"). IBM shall identify
                              ----------------------------
                   in writing to ACE any costs (including appropriate indirect
                   and overhead costs) and any profit that can be eliminated or
                   reduced in connection with the Targeted Resource Reductions
                   (the "Targeted Cost Reductions").
                         ------------------------

            (2)    Promptly upon determination of any Targeted Resource
                   Reductions, IBM shall proceed to eliminate the Targeted
                   Resource Reductions as quickly as feasible and in accordance
                   with the agreed upon schedule.

            (3)    When the Targeted Resource Reductions are eliminated, the
                   Charges specified on Schedule J shall be reduced by any
                                        ----------
                   amount of the corresponding Targeted Cost Reductions and any
                   affected Resource Baselines shall be equitably adjusted, as
                   appropriate.

            (4)    If an Extraordinary Event occurs, and ACE chooses to have IBM
                   provide additional Services related to such Extraordinary
                   Event ("Increased Services"), then IBM shall provide such
                           ------------------
                   Increased Services as soon as possible in light of the amount
                   of advance notice of such increase. The Parties will review
                   the volume of the Increased Services and agree to equitably
                   adjust the Base Charges, ARCs and RRCs and the Resource
                   Baselines and the

                        Ace/IBM Proprietary Information
                                       44
<PAGE>

                   related terms under this Agreement. Further, to the extent
                   that IBM can reasonably demonstrate to ACE that the Increased
                   Services adversely affect IBM's ability to meet the Service
                   Levels, then after IBM provides ACE written notice of such
                   impact, IBM shall be relieved of any Service Level applicable
                   to IBM's inability to meet such Service Levels for an amount
                   of time in which IBM can reasonably place additional
                   equipment in service to meet the Service Levels, but in no
                   event shall the period for such relief exceed three (3)
                   months, unless otherwise agreed in writing by the Parties.

      If an Extraordinary Event would cause a Resource Baseline to exceed 35% of
      the then current Baseline, IBM reserves the right to include additional
      fixed cost in the form of one-time charges or other variable charges to
      the Charges and/or the applicable ARC. If the Parties are unable to agree
      upon an appropriate adjustment after reasonable efforts, ACE is not
      obligated to procure such services from IBM and IBM is not obligated to
      provide such additional services to ACE.

      In no event may an Extraordinary Event which does not cause a Resource
      Baseline to exceed 35% of the then current Resource Baseline result in the
      Charges to ACE being higher than such Charges would have been if the ARCs
      and RRCs specified in Schedule J had been applied. ACE may, at its sole
                            ----------
      option, elect at any time to forego its rights under this Section 11.6 and
                                                                ------------
      instead, apply such ARCs and RRCs to adjust the Charges.

11.7  Technology

      (a)   Subject to Section 9.8, IBM shall maintain the currency level of
                       -----------
            software that will enable ACE to take advantage of technological
            advancements in its industry and support ACE's efforts to maintain
            competitiveness in the markets in which it competes. In the event of
            a significant and unanticipated change in technology that materially
            reduces IBM's costs beyond those reasonably anticipated by IBM in
            providing the Services, the Parties shall equitably adjust the
            Charges. To the extent necessary and appropriate, the Parties shall
            equitably modify and adjust the Resource Units to be measured and
            the Resource Baselines associated with such Resource Units to be
            consistent with such technological advancements.

      (b)   If IBM develops new or enhanced services, software, tools, products
            or methodologies to be offered to such customers (collectively, "New
                                                                             ---
            Technology"), IBM shall (i) offer ACE the opportunity to serve as a
            ----------
            pilot customer in connection with the implementation of such New
            Technology; and (ii) offer to implement such New Technology on an
            orderly and planned schedule taking into consideration the
            investments in the current environment.

      (c)   IBM shall meet with ACE semi-annually to brief ACE regarding
            technological developments and advances as well as new or enhanced
            services, software, tools, products or methodologies of possible
            interest or applicability to ACE. Such briefing shall include IBM's
            reasonable assessment of the business impact, performance
            improvements and cost savings associated with each.

11.8  Projects

      (a)   As part of New Services, IBM shall perform projects authorized by
            the ACE Project Executive or his or her designee. The IBM Personnel
            assigned to perform such projects shall possess the training,
            experience, competence and skill to perform such work.. The ACE
            Project Executive or his or her designee shall define and set the
            priority for such projects. ACE shall pay IBM for such authorized
            hours at the rates specified in Schedule J.
                                            ----------

                        Ace/IBM Proprietary Information
                                       45
<PAGE>

      (b)   To the extent a requested project is expected to take more than
            eighty (80) hours and unless otherwise agreed by the Parties, IBM
            shall prepare a project proposal in accordance with Section 11.5(a)
                                                                ---------------
            prior to beginning such project. ACE may accept or reject such
            project proposal in its sole discretion.

      (c)   In addition to the hours provided for in Section 11.8(a), the ACE
                                                     ---------------
            Project Executive or his or her designee may identify new or
            additional work activities to be performed by IBM Personnel
            (including work activities that would otherwise be treated as New
            Services) or reprioritize or reset the schedule for existing work
            activities to be performed by such IBM Personnel. IBM shall use
            commercially reasonable efforts to perform such work activities
            without impacting the established schedule for other tasks or the
            performance of the Services in accordance with the Service Levels.
            If it is not possible to avoid such an impact, IBM shall notify ACE
            of the anticipated impact and obtain its consent prior to proceeding
            with such work activities. ACE, in its sole discretion, may
            temporarily adjust the work to be performed by IBM, the schedules
            associated therewith or the Service Levels to permit the performance
            by IBM of such work activities.

11.9  Proration

      Periodic charges under this Agreement are to be computed on a calendar
      month basis, and shall be prorated for any partial month on a calendar day
      basis.

11.10 Refundable Items

      (a)   Prepaid Amounts. Where ACE has prepaid for a service or function for
            which IBM is assuming financial responsibility under this Agreement,
            IBM shall refund to ACE, upon either Party identifying the
            prepayment, that portion of such prepaid expense which is
            attributable to periods on and after the Commencement Date. ACE
            shall reimburse IBM, when the Term ends, for that portion of any
            amounts prepaid by IBM (or its Approved Subcontractors) that are
            attributable to periods on and after the Term ends to the extent
            that: (a) such prepayment is for a period of less than one (1) year;
            or (b) ACE approved such prepayment in advance.

      (b)   Refunds and Credits. If either Party should receive a refund,
            credit, discount or other rebate for goods or services paid for by
            the other Party, then the Party receiving such refund, credit,
            discount or other rebate shall (i) notify the other Party of such
            refund, credit, discount or rebate and (ii) pay the full amount of
            such refund, credit, discount or rebate to the other Party.

11.11 ACE Benchmarking Reviews

      (a)   Not more than once every two years during the Term and commencing
            July 1, 2002, ACE may, subject to this Section 11.11, engage the
                                                   -------------
            services of a mutually agreeable independent third party (a
            "Benchmarker") to compare the totality of the Services (including
             -----------
            the quality and cost of the Services) against the standard of well-
            managed operations performing similar services under similar
            conditions, prices, terms and environments ("Benchmarking"). Any
                                                         ------------
            Benchmarker shall agree in writing to be bound by the
            confidentiality and security provisions specified in this Agreement.
            IBM shall reasonably cooperate with ACE and the Benchmarker and will
            provide reasonable access to the Benchmarker during such effort, all
            at ACE's cost and expense. ACE shall provide IBM with a copy of the
            Benchmarker's report and IBM shall have a reasonable opportunity to
            review the Benchmarker's report and contest the Benchmarker's
            findings. If the Parties are unable to agree upon the validity of
            such findings, the matter shall be resolved pursuant to the
            procedures set forth in

                        Ace/IBM Proprietary Information

            Article 19. The Parties may agree on the results and, if
            ----------
            appropriate, a plan to adjust the price. If the Parties are unable
            to agree after using the procedures set forth in Article 19, then
                                                             ----------
            ACE may terminate this Agreement or any Tower for convenience at the
            rates specified for termination under this Section 11.11. in
                                                       -------------
            Schedule J-1.
            -------------

11.12 Changes in Laws

      (a)   At no additional charge, IBM shall comply with, and IBM shall notify
            ACE of any change in Law applicable to the delivery of the Services.
            ACE shall have the right to notify IBM of changes not previously
            communicated by IBM and IBM shall comply with such changes. IBM
            shall implement any necessary modifications to the Services prior to
            the deadline imposed by the regulatory or other governmental body
            having jurisdiction for such requirement or change. Except to the
            extent caused by ACE or the Eligible Recipients or agents, or the
            exercise by CIGNA of CIGNA's rights under the Systems Facilities
            Agreement, IBM shall be responsible for any fines or penalties
            imposed on IBM, ACE or the Eligible Recipients resulting from any
            failure by IBM or its agents, Subcontractors or third party product
            or service providers to comply with applicable Laws or respond in a
            timely manner to changes in such Laws.

      (b)   ACE shall comply with, and ACE shall notify IBM of any change in Law
            applicable to the receipt of the Services. IBM shall have the right
            to notify ACE of changes not previously communicated by ACE and ACE
            shall comply with such changes. ACE shall implement any necessary
            modifications to the receipt of Services prior to the deadline
            imposed by the regulatory or other governmental body having
            jurisdiction for such requirement or change. Except to the extent
            caused by IBM or its agents, ACE shall be responsible for any fines
            or penalties imposed on ACE, IBM or its agents resulting from any
            failure by ACE or its agents, subcontractors or third party product
            or service providers to comply with applicable Laws or respond in a
            timely manner to changes in such Laws.

12.   INVOICING AND PAYMENT

12.1  Invoicing

      (a)   IBM will invoice ACE during the Term the proportional amount of the
            Charges for that month in advance. The invoice will state separately
            applicable taxes owed by ACE, if any, by tax jurisdiction. If IBM
            invoices ACE by the first (1st) day of a month, ACE shall pay IBM
            for all undisputed invoiced Charges (subject to Section 12.4) on or
                                                            ------------
            before the last day of that month; otherwise, ACE will pay all
            undisputed invoiced Charges (subject to Section 12.4) within thirty
                                                    ------------
            (30)days after the date of ACE's receipt of the invoice. All
            periodic charges under this Agreement are to be computed on a
            calendar-month basis and will be prorated for any partial month,
            unless specifically stated otherwise in this Agreement. Each invoice
            shall be accompanied by details as to Charges as reasonably
            necessary (a) to meet ACE's requirements under government accounting
            rules and regulations (which rules and regulations will be
            identified by ACE and provided to IBM), and (b) to validate volumes
            and fees. The Parties will reasonably agree upon a means to satisfy
            ACE's internal accounting and chargeback requirements. IBM shall
            include the calculations, resource utilization information and
            variable charge rates used to calculate the amounts shown on the
            invoice.

      (b)   Beginning one month following the establishment of the Resource
            Baselines or as otherwise set forth in Schedule J, IBM will invoice
                                                   ----------
            ACE monthly for the ARCs and RRCs for the preceding month.

<PAGE>

      (c)   To the extent a credit may be due to ACE pursuant to this Agreement,
            IBM shall provide ACE with an appropriate credit against amounts
            then due and owing; if no further payments are due to IBM, IBM shall
            pay such amounts to ACE on the following invoice, but no less than
            thirty (30) days later.

12.2  Payment Due

      ACE shall pay each invoice by wire funds transfer or other electronic
      means acceptable to IBM to an account specified by IBM. Such payment shall
      be made in U.S. currency In the event that any payments are not received
      by IBM within five days following the due date, ACE shall also pay a late
      fee equal to the lesser of:

            (1)   one and one half percent of the amount of such payment per
                  month; or
            (2)   the maximum amount permissible by law.

12.3  Set Off

      With respect to any amount to be paid or reimbursed by ACE hereunder, ACE
      may set off against such amount any amount that IBM is obligated to pay
      ACE hereunder, or, at IBM's option, ACE may pay IBM such amount within
      thirty (30) days thereafter.

12.4  Disputed Charges

      (a)   ACE shall pay undisputed Charges when such payments are due under
            this Article 12 and Schedule J. However, ACE may withhold payment of
                 ----------     ----------
            variable Charges that ACE reasonably disputes in good faith provided
            that in no event will such withholding exceed the monthly invoice or
            cumulatively exceed two (2) months of current base Charges. Any
            amounts due above this limitation shall be paid to IBM under protest
            without waiver of any rights. If ACE in good faith disputes any
            Charges under this Agreement, ACE shall promptly notify IBM in
            writing of such disputed amount and the basis for ACE's dispute
            together with any appropriate information supporting ACE's position.
            If ACE withholds any disputed charges, such amount shall be promptly
            deposited in an interest-bearing escrow account. To the extent it is
            ultimately determined that such disputed amount is payable to IBM,
            ACE shall pay interest on such amount to the extent earned on such
            escrowed account. ACE and IBM shall address disputes in accordance
            with the procedures set forth in Article 19.
                                             ----------

      (b)   Neither the failure to dispute any Charges or amounts prior to
            payment nor the failure to withhold any amount shall constitute,
            operate or be construed as a waiver of any right ACE may otherwise
            have to dispute any Charge or amount or recover any amount
            previously paid, with interest.

      (c)   Beginning one month following the establishment of the Resource
            Baselines or as otherwise set forth in Schedule J, IBM will invoice
                                                   ----------
            ACE monthly for the ARCs and RRCs for the preceding month. In
            addition, IBM will invoice ACE and ACE agrees to pay IBM a cost of
            living adjustment ("COLA") in accordance with Schedule J, starting
                                ----                      ----------
            in January following the Commencement Date and monthly thereafter.

12.5  No Implied Charges

      Each Party shall be solely responsible for all the costs and expenses of
      performing such Party's obligations under this Agreement, and no payment
      shall be due from the other Party for the performance of such obligations
      unless such payment is expressly specified in this Agreement.

13.   ACE DATA AND OTHER PROPRIETARY INFORMATION.

13.1  ACE Ownership of ACE Data

      ACE Data is and shall remain the property of ACE. IBM shall, at IBM's
      expense for the first delivery and at ACE's expense for each delivery
      thereafter, promptly deliver to ACE in the available format and on the
      media then used by IBM to provide the Services: (a) a copy of all ACE
      Owned Materials and ACE Data (or such portions as shall be specified by
      ACE) and (b) a copy of all Developed Materials (or such portions as shall
      be specified by ACE) to the extent that ACE has paid all undisputed
      Charges (in accordamce with Section 12.4) expressly associated with such
                                  ------------
      Developed Materials. Such deliveries shall occur: (i) at any time at ACE's
      request, (ii) at the end of the Term and the completion of all requested
      Transfer Assistance Services, or (iii) with respect to particular ACE Data
      or ACE Owned Materials, at such earlier date that ACE requests such data
      because it is no longer required by IBM to perform the Services.
      Thereafter, if requested by ACE, IBM shall destroy or securely erase all
      copies of the ACE Data and ACE Owned Materials in IBM's possession or
      under IBM's control. IBM shall not withhold any ACE Data or any of the
      items specified in this Section as a means of resolving any dispute. IBM
      may retain one (1) copy of the ACE Data and ACE Owned Developed Materials
      to determine IBM's or its agents rights under this Agreement. IBM shall be
      relieved of its obligations to provide the Services to the extent that its
      performance is prevented or hindered by the return, erasure or destruction
      of ACE Data or ACE Owned Materials or reports prepared pursuant to this
      Section 13.1. Except to the extent expressly permitted under this
      ------------
      Agreement, ACE Data and ACE Owned Materials shall not be utilized by IBM
      for any purpose other than the performance of Services under this
      Agreement and shall not be disclosed (except as provided in Section 13.3),
                                                                  ------------
      sold, assigned, leased, or otherwise provided to third parties by IBM or
      commercially exploited by or on behalf of IBM or any IBM Personnel. IBM
      shall not possess or assert any lien or other right against or to ACE
      Data.

13.2  Safeguarding ACE Data

      (a)   IBM shall establish and maintain environmental, safety and facility
            procedures, data security procedures and other safeguards against
            the destruction, loss, or alteration of ACE Data in the possession
            of IBM which are (i) no less rigorous than those that are
            commercially reasonable, documented and enforced by ACE as of the
            Commencement Date, which ACE will provide to IBM, and (ii) no less
            rigorous than those maintained by IBM for its own information of a
            similar nature. ACE shall have the right to establish backup
            security for ACE Data and to keep backup copies of the ACE Data in
            ACE's possession at ACE's expense if ACE so chooses. No media on
            which ACE Data is stored may be used simultaneously to store data of
            any other customer of IBM.

      (b)   As part of the Services, IBM shall be responsible for developing and
            maintaining procedures for the reconstruction of lost ACE Data. IBM
            shall correct, at ACE's request and sole discretion and at no charge
            to ACE, any destruction, loss or alteration of any ACE Data to the
            extent caused by IBM or any IBM Personnel.

13.3  Confidentiality

      (a)   Proprietary Information. IBM and ACE each acknowledge that the other
            possesses and will continue to possess information that has been
            developed or received by it, has commercial value in its or its
            customer's business and is not in the public domain. Except as
            otherwise specifically agreed in writing by the Parties,
            "Proprietary Information" of ACE or IBM, or their respective
             -----------------------
            Affiliates, and Eligible Recipients, shall mean all information and

            Recipients or agents, respectively, whether disclosed to or accessed
            by such entity

            disclosed orally or not marked "confidential" or "proprietary" or
            with words of similar meaning at the time of disclosure, was
            subsequently summarized in writing within sixty (60) days after

            budgets and financial results, (j) premium data and loss
            information, (k) identities of agents and brokers and the nature of

            such information,

      (b)   Obligations

            (1)   IBM and ACE shall not disclose, and shall maintain the
                  confidentiality of, all Proprietary Information of the other
                  Party. ACE and IBM shall each use the same degree of care to
                  safeguard and to prevent disclosing to third parties the
                  Proprietary Information of the other as it employs to avoid
                  unauthorized disclosure, publication, dissemination,
                  destruction, loss, or alteration of its own information (or
                  information of its customers) of a similar nature, but not
                  less than reasonable care. The Parties may disclose
                  Proprietary Information to their Affiliates, auditors,
                  attorneys, accountants, consultants and Subcontractors, where
                  (i) use by such person or entity is authorized under this
                  Agreement, (ii) such disclosure is necessary for the
                  performance of such person's or entity's obligations under or
                  with respect to this Agreement or otherwise naturally occurs
                  in such person's or entity's scope of responsibility, (iii)
                  the person or entity (and its applicable officers and
                  employees) agree in writing to assume the obligations
                  substantially similar to those described in this Section 13.3,
                                                                   ------------
                  and (iv) the disclosing Party assumes full responsibility for
                  the acts or omissions of such person or entity and takes
                  reasonable measures to ensure that the Proprietary Information
                  is not disclosed or used in contravention of this Agreement.
                  Each Party's Proprietary Information shall remain the property
                  of such Party.

            (2)   Neither Party shall (i) make any copies of, or use, the
                  Proprietary Information of the other Party except as
                  contemplated by this Agreement, (ii) acquire any right in or
                  assert any lien against the Proprietary Information of the
                  other Party, (iii) sell, assign, transfer, lease, or otherwise
                  dispose of Proprietary Information to third parties or
                  commercially exploit such information, including through
                  derivative works, or (iv) refuse for any reason (including a
                  default or material breach of this Agreement by the other
                  Party) to promptly provide the other Party's Proprietary
                  Information (including copies thereof) to the other Party if
                  requested to do so (in the case of ACE Data, in the form
                  reasonably requested if ACE is paying for their return). Upon
                  expiration or any termination of this Agreement and completion
                  of each Party's obligations under this Agreement, each Party
                  shall return or destroy, as the other Party may direct, all
                  documentation in any medium that contains, refers to, or
                  relates to the other Party's Proprietary Information, and
                  retain no copies. In addition, the Parties shall take
                  reasonable steps to ensure that their employees comply with
                  these confidentiality provisions

      (c)   Exclusions. Section 13.3(b) shall not apply to any particular
                        ---------------
            information which the receiving Party can demonstrate (i) is, at the
            time of disclosure to it, in the public domain; (ii) after
            disclosure to it, is published or otherwise becomes part of the
            public domain through no fault of the receiving Party; (iii) is in
            the possession of the receiving Party at the time of disclosure to
            it; (iv) is received from a third party having a lawful right to
            disclose such information; or (v) is independently developed by the
            receiving Party without subsequent reference to Proprietary
            Information of the furnishing Party. In addition, the receiving
            Party shall not be considered to have breached its obligations under
            this Section 13.3 for disclosing Proprietary Information of the
                 ------------
            other Party as required to satisfy any legal requirement of a
            competent government body, provided that, promptly upon receiving
            any such request and to the extent that it may legally do so, such
            Party advises the other Party of the Proprietary Information to be
            disclosed and the identity of the third party requiring such
            disclosure prior to making such disclosure in order that the other
            Party may interpose an objection to such disclosure, take action to
            assure confidential handling of the Proprietary Information, or take
            such other action as it deems appropriate to protect the Proprietary
            Information. It is understood that the receipt of Proprietary
            Information under this Agreement will not limit or restrict
            assignment or reassignment of employees of ACE and IBM within or
            between the respective Parties and their Affiliates

      (d)   Residual Information. Notwithstanding anything to the contrary
            contained in this Agreement, either Party which receives Proprietary
            Information ("Recipient") may disclose, publish, disseminate, and
                          ---------
            use the ideas, concepts, know-how and techniques, related to
            Recipient's business activities in such Party's respective industry
            (i.e., the IBM Business for IBM and the ACE Business for ACE), which
            are contained in the disclosing Party's Proprietary Information, but
            solely to the extent retained in the memories of the receiving
            Party's employees who have had access to the Proprietary Information
            pursuant to this Agreement (the "Residual Information"). Nothing
                                             --------------------
            contained in this Section gives the Recipient the right to use,
            disclose, publish, or disseminate:

            (1)   the source of Residual Information;

            (2)   if the Recipient is IBM, any ideas, concepts, know-how or
                  techniques only related to the ACE Business, or, if the
                  Recipient is ACE, any ideas, concepts, know-how or techniques
                  only related to the IBM Business; or

            (3)   the business plans of the disclosing Party.

      (e)   Loss of Proprietary Information. Each Party shall: (i) promptly
            notify the other Party in writing of any possession, use, knowledge,
            disclosure, or loss of such other Party's Proprietary Information in
            contravention of this Agreement; (ii) promptly furnish to the other
            Party all known details and reasonably assist such other Party in
            investigating and/or preventing the reoccurrence of such possession,
            use, knowledge, disclosure, or loss; (iii) reasonably cooperate with
            the other Party in any investigation or litigation deemed necessary
            by such other Party to protect its rights; and (iv) promptly use all
            commercially reasonable efforts to prevent further possession, use,
            knowledge, disclosure, or loss

                        Ace/IBM Proprietary Information

            of Proprietary Information in contravention of this Agreement. Each
            party shall bear any costs it incurs in complying with this Section
                                                                        -------
            13.3(e)
            ------

      (f)   No Implied Rights. Nothing contained in this Section 13.3 shall be
                                                         ------------
            construed as obligating a Party to disclose its Proprietary
            Information to the other Party, or as granting to or conferring on a
            Party, expressly or impliedly, any rights or license to any
            Proprietary Information of the other Party.

      (g)   Survival. The Parties' obligations of non-disclosure and
            confidentiality shall survive the expiration or termination of this
            Agreement for a period of five (5) years.

      (h)   Limitation. Neither Party shall be responsible for the loss,
            corruption, damage or mistransmission of data during the
            transmission of such data by a third party telecommunications
            provider unless to the extent such loss, damage or mistransmission
            is attributable to error or either Party's failure to perform its
            obligations under this Agreement.

13.4  File Access

      ACE will have unrestricted access to, and the right to review and retain
      the relevant portion of all computer or other files containing ACE Data.
      At no time will any of such files or other materials or information be
      stored or held in a form or manner not readily accessible to ACE. IBM will
      provide to the ACE Project Executive all passwords, codes, comments, keys,
      documentation and the locations of any such files and other materials
      promptly upon the request of ACE, including Equipment and Software keys
      and such information as to format, encryption (if any) and any other
      specification or information necessary for ACE to retrieve, read, revise
      and/or maintain such files and information. Upon the request of the ACE
      Project Executive, IBM will confirm that, to the best of its knowledge,
      all files and other information provided to ACE are complete and that no
      material element, amount, or other fraction of such files or other
      information to which ACE may request access or review has been deleted,
      withheld, disguised or encoded in a manner inconsistent with the purpose
      and intent of providing full and complete access to ACE as contemplated by
      this Agreement.

14.   OWNERSHIP OF MATERIALS

14.1  ACE Owned Materials

      ACE shall be the sole and exclusive owner of the ACE Owned Materials.

14.2  Developed Materials

      (a)   Unless the Parties agree otherwise in writing, all ACE Owned
            Developed Materials shall be considered works made for hire (as that
            term is used in Section 101 of the Copyright Act) owned by ACE or
            such Eligible Recipient. If any such ACE Owned Developed Materials
            may not be considered a work made for hire under applicable law, IBM
            hereby irrevocably assigns, and shall assign, to ACE or the
            appropriate Eligible Recipient, without further consideration, all
            of IBM's right, title and interest in and to such ACE Owned
            Developed Materials, including United States and foreign
            intellectual property rights. IBM acknowledges that ACE and the
            Eligible Recipients and their successors and assigns shall have the
            right to obtain and hold in their own name any intellectual property
            rights in and to such ACE Owned Developed Materials. IBM agrees to
            execute any documents and take any other reasonable actions
            reasonably requested by ACE to effectuate the purposes of this
            Section 14.2. ACE grants to IBM a non-exclusive, non-transferable,
            ------------
            worldwide, limited right and license to use, execute, reproduce,
            display, perform, modify and distribute the ACE

            Owned Developed Materials for the sole purpose of providing the
            Services during the Term and the Transfer Assistance Period pursuant
            to this Agreement; provided, that this license does not give IBM the
                               --------
            right, and IBM is not authorized, to sublicense such ACE Owned
            Developed Materials or use them for the benefit of other customers
            or for any other purpose without ACE's prior written consent. ACE
            may, in its sole discretion and upon such terms and at such prices
            as ACE and IBM may agree, grant IBM a license to use the ACE Owned
            Developed Materials for other purposes and to sublicense the ACE
            Owned Developed Materials.

      (b)   IBM shall provide ACE with the source code and documentation for all
            such Developed Materials. IBM represents and warrants that: (i) the
            source code and documentation for such Developed Materials will be
            sufficient to allow a reasonably knowledgeable and experienced
            systems programmer to maintain and support such Materials; and (ii)
            the user documentation for such Materials will accurately describe
            in terms understandable by a typical end user the functions and
            features of such Materials and the procedures for exercising such
            functions and features.

14.3  IBM Owned Materials

      (a)   IBM shall be the sole and exclusive owner of the IBM Owned
            Materials, including United States and foreign intellectual property
            rights in such IBM Owned Materials.

      (b)   IBM shall not use any IBM Owned Materials other than those listed in
            Schedule B to provide the Services without providing written notice
            ----------
            to, and obtaining the prior written consent of, ACE. IBM hereby
            grants to ACE and the Eligible Recipients a perpetual, irrevocable,
            unlimited, fully paid-up, transferable, global, royalty-free
            license, with the right to grant sublicenses, to use, execute,
            reproduce, display, perform, modify, enhance, distribute and create
            derivative works of all IBM Owned Developed Materials as is
            necessary for ACE to provide to itself and the Eligible Recipients,
            or obtain from third parties, the Services.

      (c)   IBM shall not embed any IBM Owned Materials in any Developed
            Materials, or create any Developed Materials that require the use of
            any IBM Owned Materials to which ACE does not have a license
            pursuant to Section 14.3(b), without providing written notice to,
                        --------------
            and obtaining the prior written consent of, ACE. The Parties shall
            negotiate the terms and conditions of a license for ACE with respect
            to any such Materials.

14.4  Other Materials

      This Agreement shall not confer upon either Party intellectual property
      rights in Materials of the other Party (to the extent not covered by this
      Article 14) unless otherwise so provided elsewhere in this Agreement.

      (a)   Copyright Legends. The Parties agree to reproduce copyright legends
            which appear on any portion of the Materials which may be owned by
            third parties.

      (b)   No Implied Licenses. Except as expressly specified in this
            Agreement, nothing in this Agreement shall be deemed to grant to one
            Party, by implication, estoppel or otherwise, license rights,
            ownership rights or any other intellectual property rights in any
            Materials owned by the other Party or any Affiliate of the other
            Party (or, in the case of IBM, any Eligible Recipient).

                  has paid all undisputed Charges (in accordance with Section
                                                                      -------
                  12.4) expressly associated with such Developed Materials; and
                  ----
            (2)   following confirmation by ACE that the copies of the ACE Owned
                  Materials delivered by IBM are acceptable and the completion
                  by IBM of any Transfer Assistance Services for which such
                  Materials are required, destroy or securely erase all other
                  copies of such Materials then in IBM's possession and cease
                  using such Materials for any purpose; provided, however, that

            at its then current terms and prices for similarly situated
            customers:


            (1)   grant to ACE a, non-exclusive, non-transferable, internal-use
                  license to use, execute, reproduce, display, perform,
                  distribute, modify, enhance and create derivative works and to
                  permit a third party to use, execute, reproduce, display,
                  perform, distribute, modify, enhance and create derivative
                  works on ACE's behalf, and solely for the benefit or use of

            ACE shall be obligated to make any payments due following its
            receipt of such licenses and attributable to periods after such
            receipt to the extent IBM would have been obligated to make such
            payments if it had continued to hold the licenses in question.

      (d)   Substitute Materials. As to any Third Party licenses to be assigned
            or obtained, IBM shall have the right to license, or cause to be
            licensed, to ACE or otherwise obtain for ACE, or a third party on
            ACE's behalf, in place of Third Party Software and Materials and
            Third Party licenses, any other Materials which are sufficient to
            perform, without additional cost, support or resources and at the
            levels of efficiency required by this Agreement, the functions of
            the Third Party Software and Materials necessary to enable ACE or
            its designee to provide the Services after the expiration or
            termination of this Agreement.

15.   REPRESENTATIONS AND WARRANTIES

      IBM represents and warrants that the Services shall be executed in a
      timely and workmanlike manner, in accordance with the practices of the
      information technology outsourcing industry and the Performance Standards.
      IBM covenants that it shall use qualified individuals with experience,
      competence and skill necessary to perform the Services.




15.2  Maintenance

      IBM covenants that to the extent received in such condition from ACE and
      to the extent IBM is responsible to do so hereunder and unless otherwise
      agreed, it shall maintain the Equipment and Software (i)in good operating
      condition, subject to normal wear and tear, (ii) undertaking repairs and
      preventive maintenance on Equipment for which IBM is designated to be
      responsible hereunder in accordance with the applicable Equipment
      manufacturer's recommendations and requirements, and (iii) performing
      Software maintenance in accordance with the applicable Software vendor's
      written documentation,. For Third Party Equipment and Software no longer
      supported by the licensor or manufacturer and for which IBM is designated
      to be responsible hereunder, IBM shall use commercially reasonable efforts
      to perform maintenance as required. For Equipment and Software for which
      IBM has financial responsibility, IBM will replace such Equipment or
      Software as necessary, at no additional cost to ACE. For Software for
      which ACE has retained financial responsibility, ACE shall be responsible
      for such maintenance as performed by third parties on a Pass-Through
      Expenses basis and shall bear the cost of replacing such Software.

15.3  Efficiency and Cost Effectiveness

      IBM shall use commercially reasonable efforts to provide the Services in a
      cost-effective manner consistent with the Performance Standards. Without
      limiting the generality of the foregoing, such actions shall include:

      (a)   considering the economic circumstances in which the Services are
            provided, including the impact upon ACE and the Eligible Recipients
            of alternative technologies, applicable economies of scale, costs
            associated with compliance with Laws and IBM's projections of ACE's
            retained resource requirements;

                        Ace/IBM Proprietary Information
                                       55
<PAGE>

      (b)   making adjustments in the timing of actions (consistent with ACE's
            priorities and schedules for the Services and IBM's obligation to
            meet the Performance Standards);

      (c)   delaying or accelerating, as appropriate, the performance of
            noncritical functions within limits acceptable to ACE;

      (d)   tuning or optimizing the systems, including memory, used to perform
            the Services (including providing advice and suggestions to ACE to
            assist ACE in ACE's tuning of Applications Software to optimize
            performance and minimize costs);

      (e)   controlling its use of the ACE data network by scheduling usage,
            where possible, to low utilization periods;

      (f)   using alternative technologies to perform the Services; and

      (g)   efficiently using resources for which ACE is charged hereunder,
            consistent with industry norms, and compiling data concerning such
            efficient use in segregated and auditable form whenever possible.

      Prior to implementing any proposed change to the procedures, Equipment,
      Software or other assets or resources that IBM uses to provide the
      Services which may materially affect ACE's Retained Expenses or the use of
      the Applications Software, IBM agrees to (i) provide written notice to ACE
      which reasonably details IBM's proposed change and the potential impacts
      on ACE, (ii) discuss with ACE any objections ACE may have to IBM's
      proposed change, and (iii) obtain ACE's consent to such proposed change.
      To the extent that ACE does not consent, IBM shall be relieved of Service
      Levels to the extent that the failure to perform changes causes IBM to
      fail to meet Service Levels.

15.4  Technology

      IBM shall, without an increase in Charges to ACE, provide the Services
      using current technology that may enable ACE to take advantage of
      technological advancements in its industry and support ACE efforts to
      maintain competitiveness in the markets in which it competes.

15.5  Software

      (a)   IBM represents and warrants that it is either the owner of, or
            authorized to use, any and all Software used by IBM in providing the
            Services, subject to, the responsible Party under Article 5,
                                                              ---------

            Party Software selected by or for ACE to provide Services to
            determine whether such Software will perform in accordance with its
            published specifications. With respect to all products and services
            purchased by IBM for ACE on a cost-plus, cost-reimbursement or Pass-
            Through Expense basis during the course of performing the Services,
            IBM shall pass-through to ACE all benefits offered by the
            manufacturers and/or vendors of such products and services
            (including, without limitation, all warranties, refunds, credits,
            rebates,

                        Ace/IBM Proprietary Information
                                       56

      Each Party represents and warrants that it shall perform its
      responsibilities under this Agreement in a manner that does not infringe,
      or constitute an infringement or misappropriation of, any U.S. patent,
      copyright, trademark or similar proprietary rights conferred by contract
      or by common law or by the law of the U.S. or any state therein of any
      third party; provided, however, that the performing Party shall not have
                   --------
      any obligation or liability to the extent any infringement or
      misappropriation is caused by (i) modifications or misuse made by the
      other Party or its subcontractors without the knowledge or approval of the
      performing Party, (ii) the other Party's combination of the performing
      Party's work product or Materials with items not furnished or specified by
      the performing Party or contemplated by this Agreement, (iii) a breach of
      this Agreement by the other Party, or (iv) Third Party Software, except to
      the extent that such infringement or misappropriation arises from the
      failure of the performing Party to obtain the necessary licenses or
      Required Consents or to abide by the limitations of the applicable Third
      Party Software licenses. In addition, IBM represents and warrants that it
      will use commercially reasonable efforts to obtain intellectual property
      indemnification for ACE pursuant to any agreements that IBM enters into
      after the Commencement Date in connection with providing the Services with
      respect to Third Party Software, from the suppliers of such Software, that

            jurisdiction over the Services;

      (d)   The execution, delivery and performance of this Agreement and the
            consummation of the transactions contemplated by this Agreement have
            been duly authorized by the requisite corporate action on the part
            of such Party; and

      (e)   The execution, delivery, and performance of this Agreement shall not
            constitute a violation of any judgment, order, or decree; a material
            default under any material contract by which it or any of its

      that, to the best of its knowledge, no officer, director, employee, agent
      or representative of IBM has given any such payments, gifts, entertainment
      or other thing of value to any employee or agent of ACE. IBM also
      acknowledges that the giving of any such payments, gifts, entertainment,
      or other thing of value is strictly in violation of ACE's policy on
      conflicts of interest.

15.9  Malicious Code

      Each Party represents and warrants that it shall take commercially
      reasonable actions and precautions to prevent the introduction and
      proliferation, and reduce the effects, of any Malicious Code into ACE's
      information technology environment or any system used by IBM to provide

16.2  Risk of Loss

      Each Party shall be responsible for risk of loss of, and damage to, any
      Equipment, Software or other materials in its possession or on its

      notify the other of any damage (except normal wear and tear), destruction,
      loss, theft, or governmental taking of any item of Equipment, Software or
      other materials in the possession of such Party or on its premises of such
      Party, whether or not insured against by such Party, whether partial or
      complete, which is caused by any act, omission, fault or neglect of such
      Party ("Event of Loss"). Such Party shall be responsible for the cost of
              -------------
      any necessary repair or replacement of such Equipment, Software or other
      materials due to an Event of Loss; in the event of a ACE Event of Loss,
      such repair or replacement shall not be considered part of IBM's
      maintenance obligations. For a ACE Event of Loss, IBM shall coordinate and
      oversee repair or replacement performed by a third-party on a Pass-Through
      Expenses basis, or by IBM at agreed-upon prices.

                  criminal, administrative, or investigative action or
                  proceeding involving a claim in respect of which the
                  indemnitee will seek indemnification pursuant to any such
                  Section, the indemnitee shall notify the indemnitor of such
                  claim in writing. No delay or failure to so notify an
                  indemnitor shall relieve it of its obligations under this
                  Agreement except to the extent that such indemnitor has been
                  harmed by such delay or failure. Within fifteen (15) days
                  following receipt of written notice from the indemnitee
                  relating to any claim, but no later than five (5) days before
                  the date on which any response to a complaint or summons is
                  due, the indemnitor shall notify the indemnitee in writing
                  that the indemnitor elects to assume control of the defense
                  and settlement of that claim (a "Notice of Election").
                                                   ------------------

         (b)      Procedure Following Notice of Election. If the indemnitor
                  delivers a Notice of Election within the required notice
                  period, the indemnitor shall assume sole control over the
                  defense and settlement of the claim; provided, however, that
                                                       --------
                  (i) the indemnitor shall keep the indemnitee fully apprised at
                  all times as to the status of the defense, and (ii) the
                  indemnitor shall obtain the prior written approval of the
                  indemnitee before entering into any settlement of such claim
                  imposing any obligations or restrictions on the indemnitee or
                  ceasing to defend against such claim. The indemnitor shall not
                  be liable for any legal fees or expenses incurred by the
                  indemnitee following the delivery of a Notice of Election;
                  provided, however, that (i) the indemnitee shall be entitled
                  --------
                  to employ counsel at its own expense to participate in the
                  handling of the claim, and (ii) the indemnitor shall pay the
                  fees and expenses associated with such counsel if, in the
                  reasonable judgment of the indemnitee, based on an opinion of
                  counsel, there is a conflict of interest with respect to such
                  claim. The indemnitor shall not be obligated to indemnify the
                  indemnitee for any amount paid or payable by such indemnitee
                  in the settlement of any claim if (x) the indemnitor has
                  delivered a timely Notice of Election and such amount was
                  agreed to without the written consent of the indemnitor, (y)
                  the indemnitee has not provided the indemnitor with notice of
                  such claim and a reasonable opportunity to respond thereto, or
                  (z) the time period within which to deliver a Notice of
                  Election has not yet expired.

         (c)      Procedure Where No Notice of Election Is Delivered. If the
                  indemnitor does not deliver a Notice of Election relating to
                  any claim within the required notice period, the indemnitee
                  shall have the right to defend the claim in such manner as it
                  may deem appropriate, at the reasonable cost and expense of
                  the indemnitor. The indemnitor shall promptly reimburse the
                  indemnitee for all such reasonable costs and expenses.

                           action or proceeding involving a claim in respect of
                           which the indemnitee will seek indemnification
                           pursuant to Section 17.1(h) ACE shall notify IBM of

                           notify IBM shall relieve IBM of its obligations under
                           this Agreement except to the extent that IBM has been
                           harmed by such delay or failure.

                  (2)      Procedure for Defense. ACE shall be entitled to have
                           sole control over the defense and settlement of such
                           claim; provided, however, ACE shall obtain the prior

                           involving the payment of moneys for which IBM will
                           ultimately be financially response under Section
                                                                    -------

                           action or proceeding involving a claim in respect of
                           which the indemnitee will seek indemnification
                           pursuant to Section 17.2(j) IBM shall notify ACE of
                                       ---------------

                           harmed by such delay or failure.

                  (2)      Procedure for Defense. IBM shall be entitled to have
                           sole control over the defense and settlement of such
                           claim; provided, however, IBM shall obtain the prior

         indemnitee pursuant to Sections 17.1 through 17.5 or any other
                                -------------         ----
         provision of this Agreement, the indemnitor shall, upon payment of such
         indemnity in full, be subrogated to all rights of the indemnitee with
         respect to the claims to which such indemnification relates.

18.      LIABILITY

18.1     General Intent

         Subject to the specific provisions of this Article 18, it is the intent
                                                    ----------
         of the Parties that each Party shall be liable to the other Party for
         any actual damages incurred by the non-breaching Party as a result of
         the breaching Party's failure to perform its obligations in the manner
         required by this Agreement.

18.2     Force Majeure

         (a)      Subject to Section 18.2(d), no Party shall be liable for any
                             ---------------
                  default or delay in the performance of its obligations under
                  this Agreement if and to the extent such default or delay is
                  caused, directly or indirectly, by fire, flood, earthquake,
                  elements of nature or acts of God; wars, riots, civil
                  disorders, rebellions or revolutions, failure of
                  telecommunications carriers, strikes or lockouts or labor
                  disputes by third parties, or any other similar cause beyond
                  the reasonable control of such Party; provided, that the non-
                                                        --------
                  performing Party can not reasonably circumvent the delay
                  through the use of commercially reasonable alternate sources,
                  workaround plans or other means. A labor dispute involving a
                  Party (or, in the case of IBM, a Subcontractor) and its own
                  personnel shall not excuse such Party from its obligations
                  hereunder.

         (b)      In such event the non-performing Party shall be excused from
                  further performance or observance of the obligation(s) so
                  affected for as long as such circumstances prevail and such
                  Party continues to use commercially reasonable efforts to
                  recommence performance or observance whenever and to whatever
                  extent possible without delay. Any Party so prevented,
                  hindered or delayed in its performance shall immediately
                  notify the Party to whom performance is due by telephone (to
                  be

                  confirmed in writing within five (5) days of the inception
                  of such delay) and describe at a reasonable level of detail
                  the circumstances of such force majeure event.

         (c)      If any event described in Section 18.2(a) substantially
                                            ---------------
                  prevents, hinders, or delays the performance by IBM or one of
                  its Subcontractors of Services associated with critical ACE
                  functions (i.e., functions the non-performance of which has a
                  material adverse effect on the conduct of ACE's business) for
                  more than the initial recovery period specified in the IBM
                  disaster recovery plan under this Agreement, or, if no
                  disaster recovery plan exists, for ten (10) consecutive days,
                  ACE may procure such Services from an alternate source, and
                  IBM shall be liable for payment for such reasonable expenses
                  for services from the alternate source for so long as the
                  delay in performance shall continue, up to the charges
                  actually paid to IBM for the Services with respect to the
                  period of non-performance. In addition, if any event described
                  in Section 18.2(a) substantially prevents, hinders, or delays
                     ---------------
                  the performance by IBM or one of its Subcontractors of
                  Services associated with critical ACE functions for one
                  hundred and eighty (180) days, ACE will terminate any portion
                  of this Agreement so affected without payment of Termination
                  Charges and ACE will pay IBM any reasonable unrecovered start-
                  up costs and Out-of-Pocket Expenses associated with ramp down
                  transition costs.

         (d)      Upon the occurrence of a force majeure event, IBM shall, to
                  the extent possible, implement promptly, as appropriate, its
                  disaster recovery plan and provide disaster recovery services
                  therewith. The occurrence of a force majeure event shall not
                  relieve IBM of its obligation to implement its disaster
                  recovery plan and provide disaster recovery services.

         (e)      Except as stated in Section 18.2(c), nothing in this Section
                                      ---------------
                  shall limit or otherwise relieve ACE's obligation to pay any
                  moneys due IBM under the terms of this Agreement; provided,
                                                                    --------
                  that if IBM fails to provide Services in accordance with this
                  Agreement due to the occurrence of a force majeure event, all
                  amounts payable to IBM hereunder shall be equitably adjusted
                  in a manner such that ACE is not required to pay any amounts
                  for Services that it is not receiving.

         (f)      Without limiting IBM's obligations under this Agreement,
                  whenever a force majeure event causes IBM to allocate limited
                  resources between or among IBM's customers and Affiliates, ACE
                  shall be treated at least as favorably as other similarly
                  situated customers expending comparable amounts on an annual
                  basis for the same or substantially similar services.

18.3     Limitation of Liability

         (a)      NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR INDIRECT,
                  INCIDENTAL, COLLATERAL, CONSEQUENTIAL, EXEMPLARY, PUNITIVE OR
                  SPECIAL DAMAGES, INCLUDING LOST PROFITS, REGARDLESS OF THE
                  FORM OF THE ACTION OR THE THEORY OF RECOVERY, EVEN IF SUCH
                  PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
                  This Section 18.3(a) shall not limit IBM's right to recover
                       ---------------
                  any amounts becoming due for Services provided under the
                  Agreement.

         (b)      Except as provided below, the total aggregate liability of
                  either Party for claims for actual, direct damages asserted by
                  the other Party under or in connection with this Agreement,
                  regardless of the form of the action or the theory of
                  recovery, shall be limited, in aggregate to an amount equal to
                  the total payments received by IBM pursuant to this Agreement
                  for four (4) months prior to the month in which the first
                  event giving rise to the liability occurred.

         (c)      The limitations of liability set forth in Section 18.3(b)
                                                            ---------------
                  shall not apply with respect to (i) any obligation or failure
                  by ACE to pay any amounts due or past due and owing to IBM
                  pursuant to the terms of the Agreement; (ii) Losses by either
                  Party for bodily injury or damage to real property or tangible
                  personal property; (iii) Termination Charges assessed under
                  Sections 11.11, 20.3 or 20.4; and (iv) either Party's
                  ----------------------------
                  obligation to indemnify the other Party as provided in
                  Sections 17.1(d), 17.1(f), 17.1(i), 17.2(d), 17.2(e), 17.2(f),
                  -------------------------------------------------------------
                  17.2(k) and 17.2(l).
                  -------------------

         (d)      Notwithstanding Section 18.3(b), the total aggregate liability
                                  ---------------
                  of either Party for claims for actual, direct damages for
                  gross negligence or willful misconduct asserted by the other
                  Party under or in connection with this Agreement or for
                  indemnification under Sections 17.1(h) or 17.2(j), regardless
                                        ---------------------------
                  of the form of the action or the theory of recovery, shall be
                  limited, in aggregate to an amount equal to the total payments
                  received by IBM pursuant to this Agreement for twelve (12)
                  months prior to the month in which the first event giving rise
                  to the liability occurred.

         (e)      Failure by a Party to pay valid and accurate charges due and
                  payable hereunder will not be counted toward the liability
                  cap.

19.      CONTRACT GOVERNANCE AND DISPUTE RESOLUTION

19.1     Informal Dispute Resolution

         Prior to the initiation of formal dispute resolution procedures, the
         Parties shall first attempt to resolve their dispute informally, as
         follows:

         (a)      The Parties agree that the ACE Contract Executive and the IBM
                  Project Executive will attempt in good faith to resolve all
                  disputes. In the event the ACE Contract Executive and the IBM
                  Project Executive are unable to resolve a dispute in an amount
                  of time that either Party deems reasonable under the
                  circumstances, such party may refer the dispute for resolution
                  to the senior managers specified in Section 19.1(b) below upon

                  written notice to the other Party.

         (b)      Within five (5) business days of a notice under Section
                                                                  -------
                  19.1(a) above referring a dispute for resolution by senior
                  -------
                  managers, the ACE Contract Executive and the IBM Project
                  Executive will each prepare and provide to an IBM Director of
                  Services Delivery, Insurance Industry and an ACE Chief
                  Information Officer or their designate, respectively,
                  summaries of the relevant information and background of the
                  dispute, along with any appropriate supporting documentation,
                  for their review. The designated representatives will confer
                  as often as they deem reasonably necessary in order to gather
                  and furnish to the other all information with respect to the
                  matter in issue which the parties believe to be appropriate
                  and germane in connection with its resolution. The
                  representatives shall discuss the problem and negotiate in
                  good faith in an effort to resolve the dispute without the
                  necessity of any formal proceeding. The specific format for
                  the discussions will be left to the discretion of the
                  designated representatives, but may include the preparation of
                  agreed-upon statements of fact or written statements of
                  position.

         (c)      During the course of negotiations under Section 19.1(a) or
                                                          ---------------
                  19.1(b) above, all reasonable requests made by one Party to
                  -------
                  another for non-privileged information, reasonably related to
                  the dispute, will be honored in order that each of the parties
                  may be fully advised of the other's position.

         (d)      Formal proceedings for the resolution of a dispute may not be
                  commenced until the earlier of:

                  (1)      the senior managers under Section 19.1(b) above
                                                     ---------------
                           concluding in good faith that amicable resolution
                           through continued negotiation of the matter does not
                           appear likely;

                  (2)      thirty (30) days after the notice under Section
                                                                   -------

                           managers.

                  (3)      the dispute is submitted to non-binding mediation in
                           accordance with Section 19.2.
                                           ------------

                  This provision will not be construed to prevent a Party from
                  instituting, and a Party is authorized to institute, formal
                  proceedings earlier (i) to avoid the expiration of any
                  applicable limitations period, or (ii) to preserve a superior
                  position with respect to other creditors.

19.2     Mediation

         If after good faith negotiations conclude, the Parties are still unable
         to resolve a dispute, the dispute will be submitted to non-binding
         mediation by a mutually acceptable mediator to be chosen by the Parties
         within twenty (20) days after written notice by a Party demanding
         mediation. If the Parties cannot agree on a mediator, a mediator will
         be designated by the American Arbitration Association. Neither Party
         shall unreasonably withhold consent to the selection of the mediator
         and the Parties shall share the costs of the mediation equally. Any
         dispute which cannot be resolved between the Parties through
         negotiation or mediation shall be subject to the commencement of formal
         proceedings by either Party in court.

19.3     Jurisdiction

         Each Party irrevocably agrees that any legal action, suit or proceeding
         brought by it in any way arising out of this Agreement must be brought
         solely and exclusively in New York City, New York and each Party
         irrevocably submits to the sole and exclusive jurisdiction of the
         courts of the State of New York in personam, generally and
         unconditionally with respect to any action, suit or proceeding brought
         by it or against it by the other Party.

19.4     Continued Performance

         Each Party agrees that it shall, unless otherwise directed by the other
         Party, continue performing its obligations under this Agreement
         (including payment by ACE for the Services and providing all Services
         and Transfer Assistance Services) while any dispute is being resolved
         unless and until the Term ends.

19.5     Governing Law

         This Agreement and performance under it shall be governed by and
         construed in accordance with the applicable laws of the State of New
         York, without giving effect to the principles thereof relating to
         conflicts of laws.

19.6     Expiration of Claims

         No claims may be asserted by either Party more than two (2) years after
         the later of (i) the date ACE received the invoice containing the
         disputed charge(s) or amount(s), (ii) the date on which the act or
         omission giving rise to the claim occurred, or (iii) the date on which
         such act or omission was or should have been discovered. Failure to
         make such a claim within such two-year period shall forever bar the
         claim.

20.      TERMINATION

20.1

         (a)      If IBM:

                  (1)      commits a material breach of this Agreement, which
                           breach is not cured within thirty (30) days after
                           written notice of the breach from ACE, unless such
                           breach cannot be reasonably cured in such 30 day
                           period, in which case ACE shall not have the right to
                           terminate if IBM promptly proceeds within such 30 day
                           period to commence curing the breach and thereafter
                           provides a reasonable workaround, or functionally
                           cures the breach, within 60 days from receipt of the
                           cure notice; or

                  (2)      commits numerous breaches of its duties or
                           obligations which collectively constitute a material
                           breach of this Agreement, which breaches are not
                           cured within thirty (30) days after written notice of
                           the breaches from ACE, unless such breaches cannot be
                           reasonably cured in such 30 day period, in which case
                           ACE shall not have the right to terminate if IBM
                           promptly proceeds within such 30 day period to
                           commence curing the breach and thereafter provides a
                           reasonable workaround, or functionally cures the
                           breach, within 60 days from receipt of the cure
                           notice;

                  then ACE may, by giving written notice to IBM, terminate the
                  Term with respect to all of the Services, or, beginning July
                  1, 2002, with respect to any or all individual Towers, as of a
                  date specified in the notice of termination. IBM shall not be
                  entitled to any Termination Charges in connection with a
                  Termination for Cause.

                  At such time that the environment has reached the target
                  Resource Baselines and ACE and IBM have concluded the Service
                  Level Measurement Period, ACE and IBM will establish
                  thresholds setting forth criteria for Termination for Cause
                  for failure to meet certain Service Levels. The criteria to be
                  used in setting the thresholds shall include multiple
                  concurrent Service Level Category Failures during consecutive
                  months, or during an aggregate number of months in any twelve
                  month period, which, at a minimum, exceeds the number of
                  months required to maximize the progressive credits available
                  pursuant to Schedule E.
                              ----------

         (b)      If ACE commits a material breach of this Agreement (except for
                  material breaches caused by ACE's failure to make undisputed
                  payments as set forth in Section 20.1(c) below), which breach
                                           ---------------
                  is not cured within thirty (30) days after written notice of
                  the breach from IBM, unless such breach cannot be reasonably
                  cured in such 30 day period, in which case IBM shall not have
                  the right to terminate if ACE promptly proceeds within such 30
                  day period to commence curing the breach and thereafter
                  provides a reasonable workaround, or functionally cures the
                  breach, within 60 days from receipt of the cure notice; then
                  IBM may, by giving written notice to ACE, terminate the Term
                  with respect to all of the Services, or, beginning July 1,
                  2002, with respect to any or all individual Towers, as of a
                  date specified in the notice of termination. IBM shall not be
                  entitled to any Termination Charges in connection with a
                  Termination for Cause.

         (c)      If ACE commits a material breach of this Agreement by failing
                  to make an undisputed payment to IBM which is due and payable
                  hereunder (in accordance with Section 12.4), which breach is
                                                ============
                  not cured within thirty (30) days after such payment becomes
                  due and payable, then IBM may, by giving written notice to
                  ACE, terminate the Term with respect to all of the Services,
                  or, beginning July 1,

                        Ace/IBM Proprietary Information

<PAGE>

                  2002, with respect to any or all individual Towers, as of a
                  date specified in the notice of termination. IBM shall not be
                  entitled to any Termination Charges in connection with a
                  Termination for Cause.

20.2     Critical Services

         Without limiting ACE's rights under Section 20.1, if IBM commits a
                                             ------------
         material breach which has a significant impact on ACE's ability to
         perform a material function required by ACE's business, and IBM is
         unable to provide a reasonable workaround or functionally cure such
         breach within three (3) ACE business days, or such longer period if
         such breach requires disaster recovery services as soon as such
         services are available, ACE may, in addition to its other remedies at
         law and in equity, obtain from a third party or provide for itself such
         services which will allow ACE to conduct ACE's business until IBM has
         cured the breach or this Agreement is terminated. To the extent ACE
         continues to pay the Annual Service Charges to IBM during the period of
         breach, IBM shall reimburse ACE for all costs and expenses of obtaining
         or providing such services for up to one hundred eighty (180) days..
         The express inclusion of this remedy in this Section 20.2 does not
                                                      ------------
         limit ACE's right to use a similar remedy for other breaches by IBM of
         this Agreement.

20.3     Termination for Convenience

         ACE may terminate the Agreement for convenience and without cause at
         any time by giving IBM at least one hundred eighty (180) days prior
         written notice designating the termination date, or, beginning July 1,
         2002, with respect to any or all individual Towers. On the effective
         date of termination, ACE shall pay to IBM a Termination Charge
         calculated in accordance with Schedule J. In the event that a purported
                                       ----------
         termination for cause by ACE under Section 20.1 is determined by a
                                            ------------
         competent authority not to be properly a termination for cause, then
         such termination by ACE shall be deemed to be a termination for
         convenience under this Section 20.3.
                                ------------

20.4     Termination Upon IBM Change of Control

         In the event of a Change in Control of IBM, ACE may terminate this
         Agreement by giving IBM notice of the termination at least 90 days
         prior to the termination date specified in the notice. In the event of
         a termination of Change in Control of IBM, ACE shall pay to IBM, in
         addition to all Fees owing under this Agreement, the applicable amount
         set forth in Schedule J for termination for Change in Control of IBM.
                      ----------

20.5     ACE's Right to Extend the Termination Date

         Except in the case of a valid termination for cause by IBM (unless ACE
         agrees to pay for Services provided by or for IBM in advance and cures
         any payment default that causes such termination), ACE may elect, upon
         sixty (60) days prior written notice, to extend the effective date of
         any expiration/termination or Transfer Assistance one time, at its sole
         discretion, provided that the total of such extension will not exceed
         one hundred and eighty (180) days following the originally specified
         effective date without IBM's prior written consent. For any notice or
         notices of such extensions provided to IBM within thirty (30) days
         prior to the actual date of termination, ACE shall reimburse IBM for
         additional expenses reasonably incurred by IBM as a result thereof.

20.6     Equitable Remedies

         IBM acknowledges that, in the event it breaches (or attempts or
         threatens to breach) its obligation to provide ACE Transfer Assistance
         Services as provided in Section 4.3, ACE will be irreparably harmed. In
                                 -----------
         such a circumstance, ACE may proceed directly to court. In such event,
         IBM agrees that it will not utilize as a defense that ACE did not
         suffer harm due to IBM's breach of its obligations to provide ACE with
         Transfer Assistance Services.

                                  --------
                           remain fully liable for and shall not be relieved
                           from the full performance of all obligations under
                           this Agreement. Any Party assigning its rights or
                           obligations to an Affiliate in accordance with this

                           all or substantially all of such Party's assets,
                           without the approval of the other Party. The acquirer
                           or surviving Entity shall agree in writing to be
                           bound by the terms and conditions of this Agreement.

         relieve the other Party from responsibility for complying with the
         requirements of this Agreement, nor shall it be construed as a waiver
         of any rights under this Agreement, except as and to the extent
         otherwise expressly provided in such approval or consent.

21.10    Waiver of Default; Cumulative Remedies

                  breach thereof shall not

                  either Party at law, in equity or otherwise.

         observance subsequent to any termination or expiration of this
         Agreement shall survive any termination or expiration of this Agreement
         and continue in full force and effect. Additionally, all provisions of

              ACE COMPLETES ACQUISITION OF CIGNA'S P&C BUSINESSES;
                     ACE ANNOUNCES EXPENSE SAVINGS TARGETS;
            ACE OUTSOURCES INFORMATION TECHNOLOGY OPERATIONS TO IBM

     HAMILTON, Bermuda -- July 2, 1999--ACE Limited (NYSE:ACL) announced today
that its subsidiary, ACE INA Holdings, Inc. (ACE INA) has completed the
acquisition of the international and U.S. property and casualty insurance
businesses of CIGNA Corporation for the previously announced price of $3.45
billion in cash. The transaction is initially being financed with $1.025
billion of available cash, $400 million from a hybrid trust preferred security
and the remainder with commercial paper issuance. Ultimately, the commercial
paper will be replaced with a combination of newly issued equity, senior debt
and trust preferred securities.

     Also put in place at the closing was the previously announced reinsurance
arrangement with National Indemnity Company (a subsidiary of Berkshire Hathaway)
providing $ 1.25 billion in protection against adverse development in the run-
off operations and certain asbestos and environmental exposures of ACE INA.

     Brian Duperreault, chairman, president and chief executive officer of ACE
Limited, said: "I am extremely pleased that we have completed this historic
transaction. ACE is now a truly global specialty insurance group positioned as a
premier player in the world's insurance markets. We are focused on improving the
company's combined ratio to bring the businesses managed by ACE INA more in line
with the balance of ACE's operations, which are highly profitable."

     Dominic Frederico, ACE INA's chairman, president and chief executive
officer stated: "We are now poised to establish ACE INA as a strong, lean,
efficient company. We have assembled an excellent team and organized the company
for the future. Our management team is truly excited by the opportunities that
lie ahead."

     ACE also announced that it expects to achieve significant expense savings,
which together with the elimination of under-performing units should produce
combined ratios for the acquired companies of well below 100%.

     ACE INA has targeted an expense ratio for the U.S. businesses below 30%
compared with 38% currently. Internationally, cost reductions should reduce the
expense ratio by two to three percentage points.

     Savings are expected to result from a combination of staff and corporate
overhead reductions together with the outsourcing of the information technology
(IT) function. ACE expects that personnel reductions for the acquired companies
will be in the range of 15% and will
<PAGE>

follow a measured process that will begin immediately. Announcements regarding
staff changes will be made over the next few months and should be completed by
year-end 1999.

     ACE also announced today that it has reached a 10-year agreement with IBM
Global Services (IBM) to manage the transition and integration of the IT
infrastructure for the U.S. property casualty operations acquired from CIGNA and
to provide ongoing IT support for these operations. The outsourcing agreement
will transfer approximately 350 employees to IBM together with the software,
hardware and other facilities necessary to provide these services. These
employees are not included in the 15% referred to in the personnel reductions
above. The IBM agreement will reduce IT service costs before tax by
approximately $45 million annually. This will position ACE INA to meet existing
business commitments and take on future challenges and directions.

     The aggregate expense savings from the foregoing changes before tax are
expected to be approximately $195 million for ACE INA on an annual basis
beginning in the calendar year 2000.

     Christopher Marshall, chief financial officer of ACE Limited commented:
"The potential profitability of ACE INA, including the expense reductions, is
expected to be accretive to earnings. However, there is the potential of a
reduction in operating income from other areas of our group that could offset a
substantial portion of the accretion if the current challenging conditions in
the property and casualty insurance markets continue."

     ACE has decided to change its fiscal year-end to December 31st, which will
align ACE's fiscal year-end with the statutory year-ends of the majority of its
subsidiaries.

     ACE INA also announced a series of organizational changes and management
appointments, which are set forth in the attached exhibit.

     The ACE Group of Companies provides insurance and reinsurance for a diverse
group of international clients. At March 31, 1999, ACE Limited had approximately
$8.9 billion in assets and approximately $4.0 billion in shareholders' equity.
Following today's acquisition, operating subsidiaries are now based in nearly
fifty countries and the total assets of the combined companies are approximately
$30 billion.

Application of the Safe Harbor of the Private Securities Litigation Reform Act
of 1995:

     Certain statements made in this press release, including those relating to
projected reductions of the Company's expenses, estimated combined ratios, the
accretion of the acquisition and the Company's financing plans, are forward-
looking statements, reflecting the Company's current views with respect to
future events and financial performance and are made pursuant to the safe harbor
provisions of the Private Securities Litigation Reform Act of 1995.
<PAGE>

Such statements involve risks and uncertainties which may cause actual results
to differ from those set forth in these statements. Among other things, expense
reductions may not be achieved at projected levels to the extent that it takes
longer than anticipated to integrate the acquired business, to consolidate work
functions, to implement more efficient procedures or to sell or wind up lines of
business which do not fit within ACE's business plan or to the extent that ACE
determines that performance requires more employees, administrative expenditures
or locations than it now anticipates. Market conditions could affect financing
plans. ACE's forward-looking statements could also be affected by the levels of
new and renewal business achieved as well as market conditions affecting ACE's
investments. Also, competition in the industry, actual loss experience and
economic, regulatory, insurance and reinsurance business conditions and other
factors identified in the Company's filings with the Securities and Exchange
Commission could affect the forward-looking statements contained in this press
release. Readers are cautioned not to place undue reliance on these forward-
looking statements, which speak only as of the dates on which they are made. The
Company undertakes no obligation to publicly update or revise any forward-
looking statements, whether as a result of new information, future events or
otherwise.

          (5)    Comply with Securities Laws. It will comply with the Exchange
     Act and the Exchange Act Regulations in connection with the remarketing of
     the Preferred Securities or Subordinated Notes, as the case may be, as
     contemplated in this Agreement.

          (6)    No Purchase of Securities. Neither it nor any of its
     subsidiaries or Affiliates shall purchase or otherwise acquire, or enter
     into any agreement to purchase or otherwise acquire, any of the Preferred
     Securities or Subordinated Notes prior to the remarketing thereof by the
     Remarketing Agent, other than pursuant to this Agreement.

          (vi)   Notification of Rating Agency Action.  It will provide prompt
     notice by telephone, and if requested will confirm such notice in writing
     (which may include facsimile or other electronic transmission), to the
     Remarketing Agent of any notification or announcement by a "nationally
     recognized statistical rating organization" (as defined by the Commission
     for purposes of Rule 436(g)(2) under the Securities Act) with regard to a
     downgrade or withdrawal of the rating of any security of the Company or the
     Guarantor or the placement on what is currently called a Awatch list"or a
     Acredit watch" with negative implications of any security of the Company or
     the Guarantor.

          (vii)  Restriction on Debt Issuance. During the period commencing on
     the date on which the Remarketing Agent delivers a Remarketing Notice in
     accordance with Section 5(a)(i) and ending on the earlier of (A) the
     related

                                       10
<PAGE>

     Remarketing Settlement Date or (B) the date of the related Failed
     Remarketing, it will not, without the consent of the Remarketing Agent,
     offer, sell or contract to sell, or otherwise dispose of, directly or
     indirectly, or announce the offering of, any debt securities with a
     maturity of more than one year but fewer than three years.

          (ix) Best Efforts.  It shall use its reasonable best efforts to assist
     the Remarketing Agent in remarketing the Preferred Securities or the
     Subordinated Notes, as the case may be, in the manner contemplated in this
     Agreement.

     (2)  The Remarketing Agent hereby covenants with the Company, the Guarantor
and the Trust as follows:

          (1)  Maintain Authorizations.  The Remarketing Agent will use all of
     its reasonable efforts to maintain in full force and effect all consents of
     any governmental or other authority that are required to be obtained by it
     with respect to this Agreement and shall use all reasonable efforts to
     obtain any that may become necessary in the future.

          (2)  Comply with Laws. The Remarketing Agent shall comply in all
     material respects with all applicable laws and orders which it may be
     subject if failure so to comply would materially impair its ability to
     perform its obligations under this Agreement.

     Section 4.  Appointment and Obligations of Remarketing Agent and
Calculation Agent; Secondary Purchaser. (a) The Trust and the Company hereby
appoint BAS as Remarketing Agent and as Calculation Agent under the Trust
Agreement and the Indenture (i) to determine, in accordance with the terms
described in Section 5(b), the Reset Rate that, when applied to the Preferred
Securities (or, following the distribution of the Subordinated Notes to holders
of the Preferred Securities upon termination of the Trust, the Subordinated
Notes), shall result in the resale of all outstanding Preferred Securities (or,
if applicable, all outstanding Subordinated Notes) at a sales price equal to the
Remarketing Price; provided that the Reset Rate shall in no event exceed the
rate permitted by applicable law, (ii) to conduct a private auction of all
outstanding Preferred Securities or Subordinated Notes, as the case may be, and
(iii) to enter into a Secondary Purchase Agreement

                                       11
<PAGE>

with respect to the Preferred Securities or the Subordinated Notes, as the case
may be.

          (3)  Pursuant to the Secondary Purchase Agreement, the Secondary
Purchaser, either as the sole purchaser or as the representative of a syndicate
of purchasers designated by the Remarketing Agent, shall agree, subject to the
terms and conditions set forth therein, that the Secondary Purchaser and any
such other purchasers shall purchase such Preferred Securities or Subordinated
Notes, as the case may be, from the holders thereof at a price equal to the
Remarketing Price.

          Section 4.    Determination of Reset Date; Remarketing Procedures.

          (a)  (i)  Subject to Section 7, if the Closing Price of the Ordinary
          Shares on any Trading Day is less than the Trigger Price (a "Trigger
          Event"), the Holders of a Majority in Liquidation Amount of the Trust
          Securities, acting together as a single class, (or, if applicable, the
          holders of a majority in principal amount of the Subordinated Notes)
          (the "Requesting Holders") will have the right to require remarketing
          of the Trust Securities (or, if applicable, the Subordinated Notes).
          The Requesting Holders may exercise this right by delivering a written
          notice to the Remarketing Agent at any time on or prior to the sixth
          Business Day following the date such Trigger Event occurs. Upon
          receipt of such notice, the Remarketing Agent shall immediately
          deliver a written notice to the Company on behalf of the Requesting
          Holders (a "Remarketing Notice"). If the Requesting Holders exercise
          their option to require the remarketing of the Preferred Securities
          (or, if applicable, the Subordinated Notes), the Reset Date shall be
          the sixth Business Day after the date on which the Remarketing Notice
          is delivered by the Remarketing Agent (the "Expected Reset Date").

               (1)  If the Requesting Holders do not exercise their right to
          require the remarketing the Preferred Securities (or, if applicable,
          the Subordinated Notes), pursuant to Section 5(a)(i) above with
          respect to any Trigger Event, the Requesting Holders shall have the
          right to require the remarketing of the Preferred Securities (or, if
          applicable, the Subordinated Notes) in accordance with Section 5(a)(i)
          with respect to any subsequent Trigger Event.

               (2)  Notwithstanding Section 5(a)(i):

                                       12
<PAGE>

               (1)  the Company may, by notice to the Remarketing Agent, direct
          that the Reset Date be delayed if the Company believes it will be
          unable to meet the conditions to Remarketing in the absence of such a
          delay; and

               (2)  the Remarketing Agent may, by notice to the Company direct
          that the Reset Date be delayed if the Remarketing Agent believes that
          a Remarketing will not be successful in the absence of such a delay,

     provided that the Company and the Remarketing Agent, in either such event,
     will use their reasonable best efforts to establish a delayed Reset Date
     that is within five Business Days after the Expected Reset Date, but in no
     event later than the 15th Business Day following the date on which the
     related Remarketing Notice was delivered, or the 24th Business Day in the
     case of a Renewed Remarketing to which the provisions of Section 7 apply
     (as applicable, the "Final Reset Date").

          (3)  If the Company and the Remarketing Agent have not agreed, on or
     prior to the sixth Business Day preceding the Final Reset Date, to a Reset
     Date that is not later than the Final Reset Date, a Failed Remarketing
     shall be deemed to have occurred.

     (2)  The Company shall, by notice to the Remarketing Agent no later than
five Business Days prior to the Reset Date, select and specify five Reference
Corporate Dealers. By 3:00 p.m., New York City time, on the Reset Date, the
Remarketing Agent shall request Bids from such Reference Corporate Dealers. The
Remarketing Agent or an Affiliate or Associated Person thereof (any such person,
an

                                       13
<PAGE>

"Affiliated Bidder") may, at its option, enter a Bid. The Remarketing Agent
shall disclose to the Company the Bids obtained and determine the lowest Bid
Rate (the "Winning Bid Rate") from among the Bids obtained on the Reset Date. By
approximately 4:30 p.m., New York City time, on the Reset Date, the Remarketing
Agent shall notify the Company, the Indenture Trustee and the Property Trustee
of the Winning Bid Rate. If on a Reset Date, Bids are not submitted by at least
two Reference Corporate Dealers, or if the lowest Bid submitted would result in
a Winning Bid Rate in excess of the rate permitted by applicable law, the
Remarketing shall be deemed to be a Failed Remarketing on the corresponding
Remarketing Settlement Date. The Winning Bid Rate determined by the Remarketing
Agent, absent manifest error, shall be binding and conclusive upon the holders
of the Trust Securities, the holders of the Subordinated Notes, the Company, the
Guarantor and the Trust.

     (3)  On the Reset Date, the Remarketing Agent shall designate as the
Secondary Purchaser (the "Secondary Purchaser") the Reference Corporate Dealer
providing the Bid containing the Winning Bid Rate. If the Winning Bid Rate is
specified in the Bids submitted by two or more bidders, the Remarketing Agent
shall, in consultation with the Company, designate one of such bidders as the
Secondary Purchaser.

     (4)  On the Reset Date, the Secondary Purchaser shall enter into a
Secondary Purchase Agreement for the purchase by such Secondary Purchaser at the
Remarketing Price of the aggregate Liquidation Amount of the Preferred
Securities, with (A) a Distribution Rate equal to the Winning Bid Rate (or, if
Subordinated Notes shall have been distributed to holders of the Trust
Securities, the aggregate principal amount of Subordinated Notes with an
interest rate equal to the Winning Bid Rate) and (B) a Mandatory Redemption Date
(or, in the case of Subordinated Notes, a maturity date) on the Remarketed
Maturity Date.

     (5)  If a Remarketing shall have occurred pursuant to this Section 5 but
settlement of the purchase and sale of the Preferred Securities or Subordinated
Notes, as the case may be, does not occur on the corresponding Remarketing
Settlement Date, then, unless the provisions of Section 7 with respect to a
Renewed Remarketing shall apply, a Failed Remarketing shall be deemed to have
occurred on such Remarketing Settlement Date.

                                       14
<PAGE>

     (6)  At the time and in the manner specified in the Secondary Purchase
Agreement, the Secondary Purchaser shall pay to the Remarketing Agent on behalf
of the holders of the Preferred Securities or Subordinated Notes, as the case
may be, on the Remarketing Settlement Date, an amount of cash equal to the
Remarketing Price.

     (7)  Unless otherwise agreed among the Remarketing Agent, the paying agent
(under the Trust Agreement or Indenture, as applicable) and any Former Holder,
the Remarketing Agent shall promptly pay the Remarketing Price, less the
Remarketing Fee, to the paying agent, acting solely as agent for the Former
Holders, and the paying agent shall pay such amount to the Former Holders on the
Remarketing Settlement Date in the manner specified in the Trust Agreement or
the Indenture, as the case may be. Any amounts held by the paying agent for
payment to the Former Holders shall not be property of the Trust or the Company,
as the case may be.

     (8)  The obligation of the Remarketing Agent to make payment to the Former
Holders in connection with the Remarketing shall be limited to the extent that
the Secondary Purchaser has delivered the Remarketing Price therefor to the
Remarketing Agent.

     (9)  Any outstanding Preferred Securities (or, if applicable, Subordinated
Notes) purchased on the Remarketing Settlement Date shall be deemed to be
transferred to the Secondary Purchaser and shall be replaced in the manner
provided in Section 5(j). On and after the Remarketing Settlement Date (except
in the event of a Failed Remarketing), (A) the Trust (or the Company, in the
case of the Subordinated Notes) shall make no further payments to, and the Trust
(or the Company, in the case of the Subordinated Notes) shall have no further
obligations under the Trust Agreement (or the Indenture, in the case of the
Subordinated Notes) in respect of, the holders of such replaced securities (the
"Former Holders"), (B) the Trust (or the Company, in the case of the
Subordinated Notes) shall only be obligated to make payments to the holders of
Replacement Securities and (C) the Preferred Securities (or, if applicable, the
Subordinated Notes) of the Former Holders shall no longer represent an
obligation of, or interest in, the Trust (or the Company, in the case of the
Subordinated Notes) but shall only represent a right to receive the proceeds of
the Remarketing from the paying agent under the Trust Agreement or the
Indenture, as the case may be.

                                       15
<PAGE>

     (10) (i) The Company shall cause replacement certificates evidencing the
remarketed Preferred Securities (the "Replacement Preferred Securities") to be
executed by an Administrative Trustee on behalf of the Trust and authenticated
by the Property Trustee and (ii) the Company shall cause replacement
certificates evidencing the Subordinated Notes (the "Replacement Subordinated
Notes", and together with the Replacement Preferred Securities, the "Replacement
Securities") to be executed by an authorized signatory and authenticated by the
Indenture Trustee, in each case, in accordance with the provisions of Section 5.
If the Preferred Securities are to be purchased on the Remarketing Settlement
Date, (A) the Replacement Preferred Securities shall be delivered to the
purchaser of the remarketed Preferred Securities in accordance with the terms of
the Secondary Purchase Agreement and (B) the Replacement Subordinated Notes
shall be delivered to the Trust. If the Subordinated Notes are to be purchased
on the Remarketing Settlement Date, the Replacement Subordinated Notes shall be
delivered to the purchaser of the remarketed Subordinated Notes in accordance
with the terms of the Secondary Purchase Agreement.

     Section 5.    Reset of Distribution Rate, Mandatory Redemption Date,
Interest Rate and Maturity Date. From and including the Reset Settlement Date on
which Replacement Securities are issued, (A) the Distribution Rate on the Trust
Securities and the interest rate on the Subordinated Notes shall be the Winning
Bid Rate and (B) the Mandatory Redemption Date of the Trust Securities and the
maturity date of the Subordinated Notes shall be the Remarketed Maturity Date.

     Section 6.    Renewed Remarketing. If a Remarketing has occurred pursuant
to Section 5 that would be a Failed Remarketing pursuant to Section 5(e),
because the purchase and sale of the Preferred Securities (or, if applicable,
the Subordinated Notes) do not take place on the corresponding Remarketing
Settlement Date, and the reason for such failure shall, in the good faith
determination of the Remarketing Agent (made after consultation with the
Company), result from facts or circumstances that are not due to the action or
inaction of the Company, then the provisions of Section 5 shall apply to a
second remarketing (a "Renewed Remarketing") of the Preferred Securities (or, if
applicable, the Subordinated Notes), except that the Expected Reset Date shall
be the sixth Business Day following such corresponding Remarketing Settlement
Date; provided that only one Renewed Remarketing can occur pursuant to this
Section 7, and no Renewed Remarketing shall occur after the Final Reset Date.

                                       16
<PAGE>

     Section 7.    Remarketing Fee. With respect to the Remarketing, the
Remarketing Agent shall retain as a remarketing fee (the "Remarketing Fee") an
amount equal to 25 basis points (.25%) of the aggregate Liquidation Amount of
the remarketed Preferred Securities or 25 basis points (.25%) of the aggregate
principal amount of the Subordinated Notes, as the case may be, from the
purchase price received in connection with such Remarketing.

     Section 8.    Failed Remarketing; Contingent Purchase Obligation. The
Remarketing Agent shall give notice of any Failed Remarketing on the date such
Failed Remarketing occurs, or is deemed to occur, by 4:00 p.m., New York City
time, on the date of such Failed Remarketing, to the Company, the Property
Trustee, the Indenture Trustee and the paying agent under the Indenture. In the
case of any Failed Remarketing, the Holders of a Majority in Liquidation Amount
of the Trust Securities (or, if applicable, the holders of a majority in
principal amount of the Subordinated Notes) may, by notice in writing to the
Company not later than 15 days after the occurrence of such Failed Remarketing,
require the Company to purchase from the holders thereof, on a Pro Rata basis in
accordance with Section 9 of Annex I to the Trust Agreement, all outstanding
Trust Securities (or, if applicable, all outstanding Subordinated Notes) for a
purchase price equal to the aggregate Liquidation Amount of such Trust
Securities plus accrued but unpaid Distributions thereon (or, if applicable, the
aggregate principal amount of such Subordinated Notes plus accrued but unpaid
interest thereon). Payment of such purchase price shall be made directly to each
such holder on the tenth Business Day following the date of the notice to the
Company pursuant to the preceding sentence. Such purchase shall be without
recourse of any kind to any such holder. The parties recognize that the
occurrence of a Failed Remarketing indicates that it would not be commercially
reasonable under the circumstances to require Holders of Trust Securities (or,
if applicable, Subordinated Notes) to attempt to resell such securities
otherwise then pursuant to this Section, and that therefore in the event of any
default by the Company in its obligations under this Section, a Holder shall be
entitled to recover the price of the securities specified herein.

     Section 9.    Adjustments to Trigger Price. The "Trigger Price" shall
initially be equal to the product of 66 2/3% times the Closing Price for the
Ordinary Shares on the Closing Date. Following the determination by the
Remarketing Agent in its reasonable discretion that a Potential Adjustment Event
has occurred, the Remarketing Agent shall determine (after consultation with the
Company) whether such Potential Adjustment Event has a diluting or concentrative
effect on the

                                       17
<PAGE>

theoretical value of the Ordinary Shares and, if so, shall make the
corresponding adjustment(s), if any, to the Trigger Price. The Company shall
promptly notify the Remarketing Agent of any Potential Adjustment Event. The
Remarketing Agent may, but need not, determine the appropriate adjustment(s) by
reference to the adjustment(s) in respect of such Potential Adjustment Event
made by an options exchange to options on the Ordinary Shares traded on that
options exchange. In the event of any merger, consolidation or reorganization of
the Company, the Remarketing Agent shall determine (after consultation with the
Company) the appropriate Trigger Price as a result of such event.

     Section 10.    Replacement and Resignation of Remarketing Agent.   (a)  The
Company shall not have the right to replace BAS as the Remarketing Agent, except
in the case of bad faith, gross negligence or willful misconduct by BAS.

     (1)  BAS may resign at any time for good reason (after consultation with
the Company) and, subject to the following sentence, shall be discharged from
its duties and obligations hereunder or as Calculation Agent under the Trust
Agreement and the Indenture by giving no less than 10 days' notice. Any such
resignation shall become effective upon the Company's appointment of a successor
to perform the services that would otherwise be performed hereunder by the
Remarketing Agent or the Calculation Agent under the Trust Agreement and the
Indenture, as the case may be, and the agreement of any such successor so to
serve. Upon receiving notice from the Remarketing Agent that it wishes to resign
hereunder or as Calculation Agent under the Trust Agreement and the Indenture
stating the reasons for such resignation, the Company shall appoint such a
successor and enter into a new remarketing agreement with it as soon as
reasonably practicable.

     Section 11.    Dealing in the Securities. BAS, when acting as Remarketing
Agent hereunder or under the Secondary Purchase Agreement or when acting in its
individual or any other capacity, may, to the extent permitted by law, buy,
sell, hold or deal in any of the Preferred Securities or Subordinated Notes. The
Remarketing Agent may exercise any vote or join in any action with respect to
any Preferred Securities or Subordinated Notes owned by it as if it did not act
in any capacity hereunder. BAS, in its individual capacity, either as principal
or agent, may also engage in or have an interest in any financial or other
transaction with the Company as freely as if it did not act in any capacity
hereunder.

                                       18
<PAGE>

     Section 12.    Offering Memorandum. Promptly following a Trigger Event, the
Company shall furnish an offering memorandum (the "Offering Memorandum") to the
Remarketing Agent, in form and substance reasonably satisfactory to the
Remarketing Agent, to be used in the remarketing by the Secondary Purchaser
under the Secondary Purchase Agreement, and shall pay all expenses relating
thereto.

     Section 14.  Conditions to the Remarketing Agent's Obligations.  (a)  The
obligations of the Remarketing Agent, the Secondary Purchaser and any other
purchasers to perform their respective obligations hereunder and under the
Secondary Purchase Agreement shall be subject to the terms and conditions of the
Secondary Purchase Agreement.

     (1)  If at any time during the term of this Agreement, any Event of Default
under the Indenture or any Event of Default under the Trust Agreement, or event
that with the passage of time or the giving of notice or both would become an
Event of Default under the Indenture or an Event of Default under the Trust
Agreement, has occurred and is continuing under the Indenture or the Trust
Agreement, then the obligations and duties of the Remarketing Agent under this
Agreement shall be suspended until such default or event has been cured. The
Company shall cause the Property Trustee to provide to the Remarketing Agent
notice of all such defaults and events of which the Property Trustee is aware,
and the Subordinated Notes Issuer shall cause the Indenture Trustee to provide
to the Remarketing Agent notice of all such defaults and events of which the
Indenture Trustee is aware.

     Section 15.  Indemnification.  The Company shall indemnify and hold
harmless the Remarketing Agent and its officers and employees from and against
all actions, claims, damages, liabilities and losses, and costs and expenses
related thereto (including reasonable legal fees and costs) relating to or
arising out of actions or omissions in any capacity hereunder and in any
capacity as Calculation Agent under the Trust Agreement and the Indenture,
except actions, claims, damages, liabilities, losses, costs and expenses to the
extent caused by (a) the bad faith, gross negligence or wilful misconduct of
such indemnified party or (b) the breach by the Remarketing Agent of its
representations, warranties and covenants hereunder. This Section 15 shall
survive the termination of the Agreement, the Trust Agreement, the Indenture and
the payment in full of all obligations under the Preferred Securities or the
Subordinated Notes, as the case may be, and this Agreement, whether by purchase,
repurchase, redemption or otherwise.

                                       19
<PAGE>

     Section 13.  Termination of Remarketing Agreement. This Agreement shall
terminate as to any Remarketing Agent that is replaced on the effective date of
its replacement pursuant to Section 12(b). Notwithstanding any such termination,
the obligations of the Company set forth in Section 15 shall survive and remain
in full force and effect until all amounts payable under said Section 15 shall
have been paid in full.

     Section 14.  Remarketing Agent's Performance: Duty of Care; Power of
Attorney. The duties and obligations of the Remarketing Agent hereunder shall be
determined solely by the express provisions of this Agreement and the Secondary
Purchase Agreement.

     The Remarketing Agent hereby accepts the obligation set forth in the Trust
Agreement and the Indenture to act as attorney-in-fact for the holders of the
Preferred Securities or Subordinated Notes, as the case may be.

     Section 15.  Expenses. The Company shall pay the reasonable fees and
disbursements of the Remarketing Agent's counsel incurred in connection with any
remarketing, including any Renewed Remarketing and any Failed Remarketing and
the Company shall pay the reasonable fees, expenses and disbursements of the
Remarketing Agent and its counsel in connection with the execution and delivery
of the Secondary Purchase Agreement.

     Section 16.  Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York without reference
to the choice of law rules thereof.

     Section 17.  Term of Agreement. Except as otherwise provided herein, this
Agreement shall remain in full force and effect from the date hereof until 30
days after the earlier of (i) the date all Preferred Securities (or, if
applicable, Subordinated Notes) shall have been redeemed or purchased pursuant
to Section 9 hereof and (ii) the Reset Date in connection with a Remarketing
which is not a Failed Remarketing.

     Section 18.  Successors and Assigns. The rights and obligations of the
Company and the Guarantor hereunder may not be assigned or delegated to any
other person without the prior written consent of the Remarketing Agent. Subject
to the provisions of Section 12, the rights and obligations of the Remarketing
Agent

                                       20
<PAGE>

hereunder may not be assigned or delegated to any other person without the prior
written consent of the Company. This Agreement shall inure to the benefit of and
be binding upon the Trust, the Company, the Guarantor, the Remarketing Agent and
their respective successors and assigns. The terms "successors" and "assigns"
shall not include any purchaser of Preferred Securities or Subordinated Notes
merely as a result of such purchase. This Agreement shall inure to the benefit
of the Holders of the Preferred Securities (or, if applicable the Subordinated
Notes).

     Section 19.  Headings. Section headings have been inserted in this
Agreement as a matter of convenience of reference only, and it is agreed that
such section headings are not a part of this Agreement and shall not be used in
the interpretation of any provision of this Agreement.

     Section 20.  Severability. If any provision of this Agreement shall be held
or deemed to be or shall, in fact, be invalid, inoperative or unenforceable as
applied in any particular case in any or all jurisdictions because it conflicts
with any provisions of any constitution, statute, rule or public policy or for
any other reason, such circumstances shall not have the effect of rendering the
provision in question invalid, inoperative or unenforceable in any other case,
circumstances or jurisdiction, or of rendering any other provision or provisions
of this Agreement invalid, inoperative or unenforceable to any extent
whatsoever.

     Section 21.  Counterparts. This Agreement may be executed in counterparts,
each of which shall be regarded as an original and all of which shall constitute
one and the same document.

     Section 22.  Amendments. This Agreement may be amended by any instrument in
writing signed by the parties hereto; provided that Sections 9, 27 and 28 may
not be amended in a manner adverse to the Holders of the Preferred Securities
without the consent of each such Holder.

     Section 23.  Notices. Unless otherwise specified, any notices, requests,
consents or other communications given or made hereunder or pursuant hereto
shall be made in writing or transmitted by any standard form of
telecommunication, including telephone, telegraph or telecopy, and confirmed in
writing. All written notices and confirmations of notices by telecommunication
shall be deemed to have been validly given or made when delivered or mailed,

     Section 24.  Guarantee. The Guarantor hereby unconditionally guarantees to
the Remarketing Agent and each holder of a Trust Security (or, if applicable, of
a Subordinated Note) the due and punctual payment of all amounts payable by the
Company pursuant to this Agreement, when and as the same shall become due and
payable in accordance with the terms hereof, and the due and punctual
performance by the Company of all other obligations of the Company under this
Agreement. In case of the failure of the Company punctually to pay any amount
payable by it hereunder, the Guarantor hereby agrees to cause such payment to be
made punctually when and as the same shall become due and payable, as if such
payment were made by the Company.

     Section 25.  Senior Obligations. The obligations of the Company and the
Guarantor hereunder constitute senior unsecured obligations, and shall rank pari
passu with all other senior unsecured obligations of the Company and the
Guarantor, respectively. Such obligations are not subject to, and shall not be
affected by, the provisions of Articles 16 and 18 of the Indenture.

     Section 26.  Submission to Jurisdiction. The Guarantor agrees that any
judicial proceedings instituted in relation to any matter arising under any
Transaction Document may be brought in any United States Federal or New York
State court sitting in the Borough of Manhattan, The City of New York, New York
to the extent that such court has subject matter jurisdiction over the
controversy, and, by execution and delivery of this Agreement, the Guarantor
hereby irrevocably accepts, generally and unconditionally, the jurisdiction of
the aforesaid courts, acknowledges their competence and irrevocably agrees to be
bound by any judgement rendered in such proceeding. The Guarantor also
irrevocably and unconditionally waives for the benefit of the Remarketing Agent
and the Holders from time to time of the Securities (or, if applicable, the
Subordinated Notes) any immunity from jurisdiction and any immunity from legal
process (whether through service or notice, attachment prior to judgement,
attachment in the aid of execution, execution or otherwise) in respect of any
Transaction Document. The Guarantor hereby irrevocably designates and appoints
for the benefit of the Remarketing Agent and the Holders from time to time of
the Securities for the term of this Agreement ACE USA, Inc, Six Concourse
Parkway, Suite 2500, Atlanta, GA, 30328, facsimile: (770) 393-0888, Attention:

Richard T. Gieryn, Jr as its agent to receive on its behalf service of all
process (with a copy of all such service of process to be delivered to ACE
Limited, The ACE Building, 30 Woodbourne Avenue, Hamilton, HM08, Bermuda,
facsimile: (441) 296-7799, Attention: Peter N. Mear) brought against it with
respect to any such proceeding in any such court in The City of New York, such
service being hereby acknowledged by the Guarantor to be effective and binding
service on it in every respect whether or not the Guarantor, as the case may be,
shall then be doing or shall have at any time done business in New York. Such
appointment shall be irrevocable so long as any of the obligations of the
Guarantor hereunder remain outstanding, or until the appointment of a successor
by the Guarantor, as the case may be, and such successor's acceptance of such
appointment. Upon such acceptance, the Guarantor shall notify the Remarketing
Agent of the name and address of such successor. The Guarantor further agrees
for the benefit of the Remarketing Agent and the Holders from time to time of
the Securities to take any and all action, including the execution and filing of
any and all such documents and instruments, as may be necessary to continue such
designation and appointment of said agent in full force and effect so long as
any of the obligations of the Guarantor hereunder shall be outstanding. The
Remarketing Agent shall not be obligated and shall have no responsibility with
respect to any failure by the Guarantor to take any such action. Nothing herein
shall affect the right to serve process in any other manner permitted by any law
or limit the right of the Remarketing Agent or any Holder to institute
proceedings against the Guarantor in the courts of any other jurisdiction or
jurisdictions.

     Section 27.  Judgment Currency. All payments by the Company or the
Guarantor hereunder shall be made in lawful currency of the United States of
America ("Dollars"). The Guarantor agrees, to the fullest extent that it may
effectively do so under applicable law, that (a) if for the purpose of obtaining
judgment in any court it is necessary to convert the sum due in Dollars into a
currency in which a judgment will be rendered (the "Judgment Currency"), the
rate of exchange used shall be the rate at which in accordance with normal
banking procedures the Remarketing Agent could purchase in The City of New York
the requisite amount of Dollars with the Judgment Currency on the Business Day
preceding the day on which a final unappealable judgment is given and (b) its
obligations under this Agreement to make payments in Dollars (i) shall not be
discharged or satisfied by any tender, or any recovery pursuant to any judgment
(whether or not entered in accordance with clause (a)), in any currency other
than the Dollars, except to the extent that such tender or recovery shall result
in the actual receipt, by the payee, of the full amount of the Dollars expressed
to be payable in

                                       24
<PAGE>

respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in Dollars the amount,
if any, by which such actual receipt shall fall short of the full amount of
Dollars so expressed to be payable and (iii) shall not be affected by judgment
being obtained for any other sum due under this Agreement.

     Section 28.  Net Payments. All payments hereunder by the Guarantor
("Guarantee Payments") shall be made by the Guarantor without withholding or
deduction at source for, or on account of, any present or future taxes, fees,
duties, assessments or governmental charges of whatever nature imposed or levied
by or on behalf of the Cayman Islands or Bermuda (each, a taxing jurisdiction@)
or any political subdivision or taxing authority thereof or therein, unless such
taxes, fees, duties, assessments or governmental charges are required to be
withheld or deducted by (i) the laws (or any regulations or ruling promulgated
thereunder) of a taxing jurisdiction or any political subdivision or taxing
authority thereof or therein or (ii) an official position regarding the
application, administration, interpretation or enforcement of any such laws,
regulations or rulings (including, without limitation, a holding by a court of
competent jurisdiction or by a taxing authority in a taxing jurisdiction or any
political subdivision thereof). If a withholding or deduction at source is
required, the Guarantor shall, subject to certain limitations and exceptions set
forth below, pay to the Holder of any Security (or, if applicable, Subordinated
Note) such Additional Amounts (as defined below) as may be necessary so that
every net Guarantee Payment, after such withholding or deduction, shall not be
less than the amount due and payable pursuant to this Agreement; provided,
                                                                 --------
however, that the Guarantor shall not be required to make payment of such
- -------
Additional Amounts for or on account of:

     (1)  any tax, fee, duty, assessment or governmental change of whatever
nature which would not have been imposed but for the fact that such Holder: (A)
was a resident, domiciliary or national of, or engaged in business or maintained
a permanent establishment or was physically present in, the relevant taxing
jurisdiction or any political subdivision thereof or otherwise had some
connection with the relevant taxing jurisdiction other than by reason of the
mere ownership of such Security or receipt of a Guarantee Payment; (B) presented
such Security for payment in the relevant taxing jurisdiction or any political
subdivision thereof, unless such Security could not have been presented for
payment elsewhere; or (C) presented such Security more than 30 days after the
date on which the payment in respect of such Security first became due and
payable or provided for, whichever is later, except to

                                       25
<PAGE>

the extent that the Holder would have been entitled to such Additional Amounts
if it had presented such Security for payment on any day within such period of
30 days;

     (2)  any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

     (3)  any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of such
Security to comply with any reasonable request by the Guarantor addressed to the
Holder within 90 days of such request (A) to provide information concerning the
nationality, residence or identity of the Holder or such beneficial owner or (B)
to make any declaration or other similar claim or satisfy any information or
reporting requirement, which, in the case of (A) or (B), is required or imposed
by statute, treaty, regulation or administrative practice of the relevant taxing
jurisdiction or any political subdivision thereof as a precondition to exemption
from all or part of such tax, assessment or other governmental charge; or

     (4)  any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any Guarantee Payment to
any Holder who is a fiduciary or partnership or other than the sole beneficial
owner of such Security to the extent such payment would be required by the laws
of the relevant taxing jurisdiction (or any political subdivision or relevant
taxing authority thereof or therein) to be included in the income for tax
purposes of a beneficiary or partner or settlor with respect to such fiduciary
or a member of such partnership or a beneficial owner who would not have been
entitled to such Additional Amounts had it been the holder of the Security.

     If any withholding for or on account of any tax, fee, duty, assessment or
other governmental charge described in this Section 31 shall be required in
connection with a Guarantee Payment, the Guarantor shall specify, in a
certificate to the Holder, by taxing jurisdiction the amount, if any, required
to be withheld on such payments to such Holder, and the Guarantor agrees to pay
to such Holder the additional amounts required by this Section 31. The Guarantor
covenants to indemnify each Holder for, and to hold it harmless against, any
loss, liability or expense reasonably incurred without negligence or bad faith
on its part arising out of or in connection with actions taken or omitted by it
in reliance on any such certificate furnished pursuant to this Section 31.

     "Additional Amounts" means any additional amounts which are required
hereby, under circumstances specified herein, to be paid by the Guarantor in
respect of certain taxes, assessments or other governmental charges imposed on
Holders and which are owing to such Holders.

Ladies and Gentlemen:

     1.   Introduction. This letter agreement (the "Letter Agreement") confirms
our agreement with you ("BAS") relating to the issuance and sale of ordinary
shares, par value $0.041666667 per share (the "Ordinary Shares"), of ACE
Limited, a Cayman Islands company limited by shares (the "Company"), and certain
related matters.

     2.   Underwriting. (a) The Company shall designate by written notice to BAS
one or more target dates (each, a "Targeted Purchase Date") during the 36-month
period following the date hereof and ending on June 30, 2002 (the "Underwriting
Period") for the issuance and sale (an "Underwriting") by BAS (and potentially
other underwriters as contemplated below) of a number of Ordinary Shares (the
"Offered Shares" with respect to such Underwriting) having an aggregate Public
Offering Price (as defined below) with respect to such Underwriting equal to or
less than the Underwriting Commitment (as defined below), and the Company agrees
that it shall designate Targeted Purchase Dates so that the aggregate offering
price for all Underwritings shall equal the Initial Underwriting Commitment (as
defined below). If Underwritings having an aggregate public offering price of at
least the Initial Underwriting Commitment have not been completed prior to the
60th day preceding the end of the Underwriting Period, BAS shall be entitled to
designate a Targeted Purchase Date for an Underwriting of Offered Shares having
an aggregate Public Offering Price equal to the Underwriting Commitment by
written notice to the Company, which Targeted Purchase Date shall not be later
than the last day of the Underwriting Period.

          "Underwriting Commitment" means the excess, if any, of (i)
     $400,000,000 (the "Initial Underwriting Commitment") over (ii) the
<PAGE>

     aggregate Public Offering Price (as defined below) of all Ordinary Shares
     (including any Additional Shares purchased pursuant to Section 2(c) below)
     sold in any Underwriting that has been completed prior to such date.

     (b)  Prior to each Targeted Purchase Date, each of the Company and BAS will
cooperate with the other party and use its reasonable best efforts to market the
Offered Shares.  Once marketing is complete, each of the Company and the
Underwriter will use its reasonable best efforts to agree to the terms,
including without limitation any pricing terms, of a firm commitment
underwriting and upon such agreement, enter into a Firm Commitment Underwriting
Agreement (the "Firm Commitment Underwriting Agreement") with respect to such
Offered Shares, substantially in the form of the Underwriting Agreement attached
hereto, with such changes as are mutually agreed to by BAS and the Company to
reflect the terms of the firm commitment underwriting and changed circumstances
and practices; provided that (i) so long as Offerings are consummated hereunder
during the Underwriting Period for an aggregate Public Offering Price at least
equal to the Initial Underwriting Commitment, the Company shall be under no
obligation to accept the proposed terms of any particular Offering and (ii) the
Company may designate additional underwriters, as provided for below.
Notwithstanding anything herein to the contrary, either the Company or BAS may
decline to enter into such Firm Commitment Underwriting Agreement if it believes
that doing so might result in any violation of applicable law or regulation.

     (c)  In the Firm Commitment Underwriting Agreement with respect to any
Underwriting, the Company will grant to the underwriters in such Firm Commitment
Underwriting Agreement the right to purchase at the Purchase Price (as defined
below) a number of additional Ordinary Shares (the "Additional Shares") not to
exceed 15% of the Offered Shares to be sold in such Underwriting.

     (d)  Subject to Section 2(e) below, the purchase price per Offered Share
(the "Purchase Price") to be paid by BAS to the Company pursuant to any Firm
Commitment Underwriting Agreement shall be equal to 97.50% of the price at which
each Offered Share is initially to be offered to the public (the "Public
Offering Price").

     (e)  The parties contemplate that any Underwritings hereunder will be
solely underwritten by BAS. The Company may elect to include another broker-
dealer as a joint book-running manager together with BAS in any Underwriting
hereunder and one or more co-managing underwriters; provided that in such event,
the Purchase Price in such Underwriting shall be equal to 97.0% of the

                                       2
<PAGE>

Public Offering Price, and BAS shall be entitled to at least 50% of any
applicable management fees, underwriting discounts and commissions (1.50% of the
Public Offering Price); provided further that BAS shall be entitled to at least
25% of such fees, discounts and commissions (0.75% of the Public Offering Price)
if, in the reasonable judgment of the Company prior to the marketing of such
offering, BAS is unable to meet the standards of other nationally recognized
investment banks in connection with such Underwriting, it being understood that
BAS shall be deemed to be unable to meet the standards of other nationally
recognized investment banks in connection with such an Underwriting only if a
significant decline in BAS's current equity distribution capabilities occurs.

     3.   Shelf Registration. The Company has prepared and filed with the
Securities and Exchange Commission a registration statement on Form S-3
("Registration Statement") relating to the offer and sale of Ordinary Shares and
other securities, with a proposed aggregate public offering price equal to
$4,000,000,000, on a continuous or delayed basis pursuant to Rule 415 under the
Securities Act of 1933, as amended (the "1933 Act").  The Company shall use its
reasonable best efforts to (i) if necessary, cause the Registration Statement to
become effective under the 1933 Act as soon as practicable after such filing and
(ii) keep the Registration Statement effective with unused capacity at least
equal to 115% of the Underwriting Commitment until the conclusion of the
Underwriting Period.

     4.   Termination. This Letter Agreement will terminate on the earliest of
(i) the date on which the underwritings contemplated hereby are completed, (ii)
the last day of the Underwriting Period and (iii) July 9, 1999 if the closing
under the Placement Agreement dated as of June 29, 1999 among the Company, ACE
INA Holdings Inc., a Delaware corporation, ACE RHINOS Trust, a Delaware business
trust, and Intrepid Funding Master Trust, a Delaware business trust, has not
occurred.

     5.   Expenses. Except as otherwise provided in each Firm Commitment
Underwriting Agreement, all costs and expenses (including any fees,
disbursements and expenses of counsel) incurred in connection with this Letter
Agreement and the Underwritings contemplated hereby shall be paid by the party
incurring such expenses; provided that if the underwritings contemplated hereby
are not completed prior to conclusion of the Underwriting Period, the Company
will pay all such expenses incurred by BAS or any of its affiliates.

     6.   Governing Law. This Letter Agreement shall be governed by and
construed in accordance with the substantive law of the State of New York.

                                       3
<PAGE>

     7.   Binding Obligation; Reasonable Best Efforts. It is understood that
this Letter Agreement constitutes a legally binding obligation of the parties
hereto. The parties agree to use their reasonable best efforts to take, or cause
to be taken, all actions and to do, or cause to be done, all things necessary to
consummate the transactions contemplated by this Letter Agreement.

     8.   Counterparts. This Letter 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.

     9.   Purchase for Resale. BAS confirms its intention that any Ordinary
Shares purchased by it pursuant to this Letter Agreement will be purchased for
resale to third parties pursuant to a bona fide public offering.

     Section 1.4.  Acts of Holders.

          (1)      Any request, demand, authorization, direction, notice,
     consent, waiver or other action provided by or pursuant to this Indenture
     to be given or taken by Holders or by holders of Preferred Securities may
     be embodied in and evidenced by one or more instruments of substantially
     similar tenor signed by such Holders or holders of Preferred Securities, as
     applicable, in person or by an agent duly appointed in writing. If, but
     only if, Securities of a series are issuable as Bearer Securities, any
     request, demand, authorization, direction, notice, consent, waiver or other
     action provided in or pursuant to this Indenture to be given or taken by
     Holders of Securities of such series may,

                                       15
<PAGE>

     alternatively, be embodied in and evidenced by the record of Holders of
     Securities of such series voting in favor thereof, either in person or by
     proxies duly appointed in writing, at any meeting of Holders of Securities
     of such series duly called and held in accordance with the provisions of
     Article 15, or a combination of such instruments and any such record.
     Except as herein otherwise expressly provided, such action shall become
     effective when such instrument or instruments or record or both are
     delivered to the Trustee and, where it is hereby expressly required, to the
     Company or the Guarantor or both of them. Such instrument or instruments
     and any such record (and the action embodied therein and evidenced thereby)
     are herein sometimes referred to as the "Act" of the Holders or holders of
     Preferred Securities signing such instrument or instruments or so voting at
     any such meeting. Proof of execution of any such instrument or of a writing
     appointing any such agent, or of the holding by any Person of a Security,
     shall be sufficient for any purpose of this Indenture and (subject to
     Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee,
     the Company and the Guarantor and any agent of the Trustee, the Company or
     the Guarantor, if made in the manner provided in this Section. The record
     of any meeting of Holders of Securities shall be proved in the manner
     provided in Section 15.6.

          Without limiting the generality of this Section 1.4, unless otherwise
     provided in or pursuant to this Indenture, a Holder, including a U.S.
     Depository that is a Holder of a global Security, may make, give or take,
     by a proxy or proxies, duly appointed in writing, any request, demand,
     authorization, direction, notice, consent, waiver or other Act provided in
     or pursuant to this Indenture to be made, given or taken by Holders, and a
     U.S. Depository that is a Holder of a global Security may provide its proxy
     or proxies to the beneficial owners of interests in any such global
     Security through such U.S. Depository's standing instructions and customary
     practices.

          The Company shall fix a record date for the purpose of determining the
     Persons who are beneficial owners of interest in any permanent global
     Security held by a U.S. Depository entitled under the procedures of such
     U.S. Depository to make, give or take, by a proxy or proxies duly appointed
     in writing, any request, demand, authorization, direction, notice, consent,
     waiver or other Act provided in or pursuant to this Indenture to be made,
     given or taken by Holders.  If such a record date is fixed, the Holders on
     such record date or their duly appointed proxy or proxies, and only such
     Persons, shall be entitled to make, give or take such request, demand,
     authorization, direction, notice, consent, waiver or other Act, whether or
     not such Holders remain Holders after such record date.  No such request,
     demand, authorization, direction, notice, consent, waiver or other Act
     shall be valid or  effective if made, given or taken more than 90 days
     after such record date.

          (2)  The fact and date of the execution by any Person of any such
     instrument or writing referred to in this Section 1.4  may be proved in any
     reasonable manner; and the Trustee may in any instance require further
     proof with respect to any of the matters referred to in this Section.

                                       16
<PAGE>

          (3)  The ownership, principal amount and serial numbers of Registered
     Securities held by any Person, and the date of the commencement and the
     date of the termination of holding the same, shall be proved by the
     Security Register.

          (4)  The ownership, principal amount and serial numbers of Bearer
     Securities held by any Person, and the date of the commencement and the
     date of the termination of holding the same, may be proved by the
     production of such Bearer Securities or by a certificate executed, as
     depositary, by any trust company, bank, banker or other depositary
     reasonably acceptable to the Company and the Guarantor, wherever situated,
     if such certificate shall be deemed by the Company, the Guarantor and the
     Trustee to be satisfactory, showing that at the date therein mentioned such
     Person had on deposit with such depositary, or exhibited to it, the Bearer
     Securities therein described; or such facts may be proved by the
     certificate or affidavit of the Person holding such Bearer Securities, if
     such certificate or affidavit is deemed by the Trustee to be satisfactory.
     The Trustee, the Company and the Guarantor may assume that such ownership
     of any Bearer Security continues until (i) another certificate or affidavit
     bearing a later date issued in respect of the same Bearer Security is
     produced, or (ii) such Bearer Security is produced to the Trustee by some
     other Person, or (iii) such Bearer Security is surrendered in exchange for
     a Registered Security, or (iv) such Bearer Security is no longer
     Outstanding.  The ownership, principal amount and serial numbers of Bearer
     Securities held by the Person so executing such instrument or writing and
     the date of the commencement and the date of the termination of holding the
     same may also be proved in any other manner which the Company, the
     Guarantor and the Trustee deem sufficient.

          (5)  If the Company or the Guarantor shall solicit from the Holders of
     any Registered Securities any request, demand, authorization, direction,
     notice, consent, waiver or other Act, the Company or the Guarantor, as the
     case may be, may at its option (but is not obligated to), by Board
     Resolution or Guarantor's Board Resolution, as the case may be, fix in
     advance a record date for the determination of Holders of Registered
     Securities entitled to give such request, demand, authorization, direction,
     notice, consent, waiver or other Act.  If such a record date is fixed, such
     request, demand, authorization, direction, notice, consent, waiver or other
     Act may be given before or after such record date, but  only the Holders of
     Registered Securities of record at the close of business on such record
     date shall be deemed to be Holders for the purpose of determining whether
     Holders of the requisite proportion of Outstanding Securities have
     authorized or agreed or consented to such request, demand, authorization,
     direction, notice, consent, waiver or other Act, and for that purpose the
     Outstanding Securities shall be computed as of such record date; provided
     that no such authorization, agreement or consent by the Holders of
     Registered Securities shall be deemed effective unless it shall become
     effective pursuant to the provisions of this Indenture not later than six
     months after the record date.

          (6)  Any request, demand, authorization, direction, notice, consent,
     waiver or other Act by the Holder of any Security shall bind every future
     Holder of the same Security and the Holder of every Security issued upon
     the registration of transfer thereof

                                       17
<PAGE>

     or in exchange therefor or in lieu thereof in respect of anything done or
     suffered to be done by the Trustee, any Security Registrar, any Paying
     Agent, the Guarantor or the Company in reliance thereon, whether or not
     notation of such Act is made upon such Security.

     Section 1.5.  Notices, etc. to Trustee, Company and Guarantor.

     Any request, demand, authorization, direction, notice, consent, waiver or
other Act of Holders or other document provided or permitted by this Indenture
to be made upon, given or furnished to, or filed with,

          (1)      the Trustee by any Holder, the Guarantor or the Company shall
     be sufficient for every purpose hereunder if made, given, furnished or
     filed in writing to or with the Trustee at its Corporate Trust Office, or

          (2)      the Company or the Guarantor, as the case may be, by the
     Trustee or any Holder shall be sufficient for every purpose hereunder
     (unless otherwise herein expressly provided) if in writing and mailed,
     first-class postage prepaid, to the Company or the Guarantor, as the case
     may be, addressed to the attention of its Treasurer, with a copy to the
     attention of its General Counsel, at the address of its principal office
     specified in the first paragraph of this instrument or at any other address
     previously furnished in writing to the Trustee by the Company or the
     Guarantor, as the case may be.

     Section 1.6.  Notice to Holders of Securities; Waiver.

     Except as otherwise expressly provided in or pursuant to this Indenture,
where this Indenture provides for notice to Holders of Securities of any event,

          (1)      such notice shall be sufficiently given to Holders of
     Registered Securities if in writing and mailed, first-class postage
     prepaid, to each Holder of a Registered Security affected by such event, at
     his address as it appears in the Security Register, not later than the
     latest date, and not earlier than the earliest date, prescribed for the
     giving of such notice; and

          (2)      such notice shall be sufficiently given to Holders of Bearer
     Securities, if any, if published in an Authorized Newspaper in The City of
     New York and, if such Securities are then listed on any stock exchange
     outside the United States, in an Authorized Newspaper in such city as the
     Company shall advise the Trustee that such stock exchange so requires, on a
     Business Day at least twice, the first such publication to be not earlier
     than the earliest date and the second such publication not later than the
     latest date prescribed for the giving of such notice.

     In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of

                                       18
<PAGE>

Registered Securities or the sufficiency of any notice to Holders of Bearer
Securities given as provided herein. Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given or
provided. In the case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

     In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder.  Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such  waiver shall be the equivalent of such notice.
Waivers of notice by Holders of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

     Section 1.7.  Language of Notices.

     Any request, demand, authorization, direction, notice, consent, election or
waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company or the Guarantor, as the case may be, so
elects, any published notice may be in an official language of the country of
publication.

     Section 1.8.  Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

     Section 1.9.  Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

     Section 1.10. Successors and Assigns.

     Section 1.11.  Separability Clause.

     In case any provision in this Indenture, any Security or any Coupon shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

     Section 1.12.  Holders of Preferred Securities as Third Party
Beneficiaries.

     The Company and the Guarantor hereby acknowledge that, to the extent
specifically set forth herein, the holders of the Preferred Securities of an ACE
Trust shall expressly be third party beneficiaries of this Indenture.  The
Company and the Guarantor further acknowledge that, if an Event of Default has
occurred and is continuing and is attributable to the failure of the Company and
the Guarantor to pay the principal of or premium, if any, or interest on or
Additional Amounts with respect to the Securities of the series held by such ACE
Trust, any holder of the Preferred Securities of such ACE Trust may institute a
Direct Action against the Company or the Guarantor.

     Section 1.13.  Benefits of Indenture.

     Except as other expressly provided herein with respect to holders of
Preferred Securities, nothing in this Indenture, any Security or any Coupon,
express or implied, shall give to any Person, other than the parties hereto and
the holders of Senior Indebtedness, any Security Registrar, any Paying Agent,
any Authenticating Agent and their successors hereunder and the Holders of
Securities or Coupons, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

     Section 1.14.  Governing Law.

     This Indenture, the Securities and any Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made or instruments entered into and, in each case, performed in said
state.

     Section 1.15.  Legal Holidays.

     Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security, or the last date on which a Holder has the right to
convert or exchange Securities of a series that are convertible or exchangeable,
shall not be a Business Day at any Place of Payment, then (notwithstanding any
other provision of this Indenture, any Security or any Coupon other than a
provision in any Security or Coupon that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and such Securities need not be converted or exchanged on such date,
but such payment may be made, and such Securities may be converted or exchanged,
on the next succeeding day that is a Business Day at such Place of Payment, and
no interest shall accrue on the amount payable on such date or at such time for

conversion or exchange, as the case may be, to such next succeeding Business

     Section 1.16.  Counterparts.

     This Indenture may be executed in several counterparts, each of which shall
be an original and all of which shall constitute but one and the same
instrument.

     Section 1.17.  Judgment Currency.

     The Company and the Guarantor each agrees, to the fullest extent that it
may effectively do so under applicable law, that (a) if for the purpose of
obtaining judgment in any court it is necessary to convert the sum due in
respect of the principal of, or premium or interest, if any, or Additional
Amounts on the Securities of any series (the "Required Currency") into a
currency in which a judgment will be rendered (the "Judgment Currency"), the
rate of exchange used shall be the rate at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York the
requisite amount of the Required Currency with the Judgment Currency on the New
York Banking Day preceding the day on which a final unappealable judgment is
given and (b) its obligations under this Indenture to make payments in the
Required Currency (i) shall not be discharged or satisfied by any tender, or any
recovery pursuant to any judgment (whether or not entered in accordance with
clause (a)), in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the actual receipt, by the
payee, of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required
Currency the amount, if any, by which such actual receipt shall fall short of
the full amount of the Required Currency so expressed to be payable and (iii)
shall not be affected by judgment being obtained for any other sum due under
this Indenture.  For purposes of the foregoing, "New York Banking Day" means any
day except a Saturday, Sunday or a legal holiday in The City of New York or a
day on which banking institutions in The City of New York are authorized or
obligated by law, regulation or executive order to be closed.

     Section 1.18.  No Security Interest Created.

     Nothing in this Indenture or in any Securities, express or implied, shall
be construed to constitute a security interest under the Uniform Commercial Code
or similar legislation, as now or hereafter enacted and in effect in any
jurisdiction where property of the Company, the Guarantor or their respective
Subsidiaries is or may be located.

otherwise in respect thereof, shall be had against any incorporator, shareholder
(except in a shareholder's corporate capacity as Guarantor), officer or
director, as such, past, present or future, of the Company or the Guarantor, as
the case may be, either directly or through the Company or the Guarantor, as the

manner and by such Person or Persons as shall be specified therein or in the
Company Order to be delivered pursuant to Section 3.3 or 3.4 with respect
thereto.  Subject to the provisions of Section 3.3 and, if applicable, Section

been, or simultaneously is, delivered, any instructions by the Company with
respect to a Security in global form shall be in writing but need not be
accompanied by or contained in an Officer's Certificate and need not be
accompanied by an Opinion of Counsel.

     Notwithstanding the provisions of Section 3.7, unless otherwise specified
in or pursuant to this Indenture or any Securities, payment of principal of, any
premium and interest on, and any Additional Amounts in respect of, any Security
in temporary or permanent global form shall be made to the Person or Persons
specified therein.

     Notwithstanding the provisions of Section 3.8 and except as provided in the
preceding paragraph, the Company, the Guarantor, the Trustee and any agent of
the Company, the Guarantor or the Trustee shall treat as the Holder of such
principal amount of Outstanding Securities represented by a global Security (i)
in the case of a global Security in registered form,

                                       24

global Security in bearer form, the Person or Persons specified pursuant to
Section 3.1.

shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

     (1)  an Opinion of Counsel to the effect that:

          (a)  the form or forms and terms of such Securities and Coupons, if
     any, have been established in conformity with the provisions of this
     Indenture;

          (b)  all conditions precedent to the authentication and delivery of
     such Securities and Coupons, if any, appertaining thereto, have been
     complied with and that such Securities and Coupons, when completed by
     appropriate insertions, executed under the Company's corporate seal and
     attested by duly authorized officers of the Company, delivered by duly
     authorized officers of the Company to the Trustee for authentication
     pursuant to this Indenture, and authenticated and delivered by the Trustee
     and issued by the Company in the manner and subject to any conditions
     specified in such Opinion of Counsel, will constitute legally valid and
     binding obligations of the Company, enforceable against the Company in
     accordance with their terms, except as enforcement thereof may be subject
     to or limited by bankruptcy, insolvency, reorganization, moratorium,
     arrangement, fraudulent conveyance, fraudulent transfer or other similar
     laws relating to or affecting creditors' rights generally, and subject to
     general principles of equity (regardless of whether enforcement is sought
     in a proceeding in equity or at law) and will entitle the Holders thereof
     to the benefits of this Indenture, including the Guarantee; such Opinion of
     Counsel need express no opinion as to the availability of equitable
     remedies; and

          (c)  all laws and requirements in respect of the execution and
     delivery by the Company of such Securities and Coupons, if any, have been
     complied with;

                                       30
<PAGE>

and, to the extent that this Indenture is required to be qualified under the
Trust Indenture Act in connection with the issuance of such Securities, to the
further effect that:

          (d)  this Indenture has been qualified under the Trust Indenture Act;
     and

     (2)  an Officer's Certificate and a Guarantor's Officer's Certificate, in
each case stating that, to the best knowledge of the Persons executing such
certificate, all conditions precedent to the execution, authentication and
delivery of such Securities and Coupons, if any, appertaining thereto, have been
complied with, and no event which is, or after notice or lapse of time would
become, an Event of Default with respect to any of the Securities shall have
occurred and be continuing.

     If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel and an Officer's
Certificate and Guarantor's Officer's Certificate at the time of issuance of
each Security, but such opinion and certificates, with appropriate
modifications, shall be delivered at or before the time of issuance of the first
Security of such series.  After any such first delivery, any separate written
request by an Authorized Officer of the Company or any person designated in
writing by an Authorized Officer that the Trustee authenticate and deliver
Securities of such series for original issue will be deemed to be a
certification by the Company and the Guarantor that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with and that no Event of Default with
respect to any of the Securities has occurred or is continuing.

     The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

     Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

     No Security or Coupon appertaining thereto shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose, unless there
appears on such Security a certificate of authentication substantially in the
form provided for in Section 2.2 or 6.11 executed by or on behalf of the Trustee
or by the Authenticating Agent by the manual signature of one of its authorized
officers.  Such certificate upon any Security shall be conclusive evidence, and
the only evidence, that such Security has been duly authenticated and delivered
hereunder.  Except as permitted by Section 3.6 or 3.7, the Trustee shall not
authenticate and deliver any Bearer Security unless all Coupons appertaining
thereto then matured have been detached and cancelled.

     Section 3.4. Temporary Securities.

     Pending the preparation of definitive Securities, the Company may execute
and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 3.3, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities.  Such temporary
Securities may be in global form.

     Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities are
issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay.  After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof.  Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture.  Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

     Section 3.5. Registration, Transfer and Exchange.

     With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series.  Such Office or Agency shall be the "Security Registrar" for that series
of Securities.  Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities.  The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment

                                       32
<PAGE>

by the Company. In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

     Upon surrender for registration of transfer of any Registered Security of
any series at any Office or Agency for such series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Registered Securities of the same
series denominated as authorized in or pursuant to this Indenture, of a like
aggregate principal amount bearing a number not contemporaneously outstanding
and containing identical terms and provisions.

     At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series.  Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

     If provided in or pursuant to this Indenture, with respect to Securities of
any series, at the option of the Holder, Bearer Securities of such series may be
exchanged for Registered Securities of such series containing identical terms,
denominated as authorized in or pursuant to this Indenture and in the same
aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining.  If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company,
the Guarantor and the Trustee in an amount equal to the face amount of such
missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons
may be waived by the Company, the Guarantor and the Trustee if there is
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless.  If thereafter the Holder of such Bearer
Security shall surrender to any Paying Agent any such missing Coupon in respect
of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment; provided, however, that, except as otherwise
provided in Section 10.2, interest represented by Coupons shall be payable only
upon presentation and surrender of those Coupons at an Office or Agency for such
series located outside the United States.  Notwithstanding the foregoing, in
case a Bearer Security of any series is surrendered at any such Office or Agency
for such series in exchange for a Registered Security of such series and like
tenor after the close of business at such Office or Agency on (i) any Regular
Record Date and before the opening of business at such Office or Agency on the
next succeeding Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such Office or Agency on the related date for
payment of Defaulted Interest, such Bearer Security shall be surrendered without
the Coupon relating to such Interest Payment Date

                                       33
<PAGE>

or proposed date of payment, as the case may be (or, if such Coupon is so
surrendered with such Bearer Security, such Coupon shall be returned to the
Person so surrendering the Bearer Security), and interest or Defaulted Interest,
as the case may be, shall not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

     If provided in or pursuant to this Indenture with respect to Securities of
any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

     Whenever any Securities are surrendered for exchange as contemplated by the
immediately preceding two paragraphs, the Company shall execute, and the Trustee
shall authenticate and deliver, the Securities which the Holder making the
exchange is entitled to receive.

     Notwithstanding the foregoing, except as otherwise provided in or pursuant
to this Indenture, any global Security shall be exchangeable for definitive
Securities only if (i) the Depository is at any time unwilling, unable or
ineligible to continue as depository and a successor depository is not appointed
by the Company within 90 days of the date the Company is so informed in writing,
(ii) the Company executes and delivers to the Trustee a Company Order to the
effect that such global Security shall be so exchangeable, or (iii) an Event of
Default has occurred and is continuing with respect to the Securities.  If the
beneficial owners of interests in a global Security are entitled to exchange
such interests for definitive Securities as the result of an event described in
clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary
delay but in any event not later than the earliest date on which such interests
may be so exchanged, the Company shall deliver to the Trustee definitive
Securities in such form and denominations as are required by or pursuant to this
Indenture, and of the same series, containing identical terms and in aggregate
principal amount equal to the principal amount of such global Security, executed
by the Company.  On or after the earliest date on which such interests may be so
exchanged, such global Security shall be surrendered from time to time by the
U.S.  Depository or such other Depository as shall be specified in the Company
Order with respect thereto, and in accordance with instructions given to the
Trustee and the U.S. Depository or such other Depository, as the case may be
(which instructions shall be in writing but need not be contained in or
accompanied by an Officer's Certificate or be accompanied by an Opinion of
Counsel), as shall be specified in the Company Order with respect thereto to the
Trustee, as the Company's agent for such purpose, to be exchanged, in whole or
in part, for definitive Securities as described above without charge.  The
Trustee shall authenticate and make available for delivery, in exchange for each
portion of such surrendered global Security, a like aggregate principal amount
of definitive Securities of the same series of authorized denominations and of
like tenor as the portion of such global Security to be exchanged, which (unless
such Securities are not issuable both as Bearer Securities and as Registered
Securities, in which case the definitive Securities exchanged for the global
Security shall be issuable only in the form in

                                       34
<PAGE>

which the Securities are issuable, as provided in or pursuant to this Indenture)
shall be in the form of Bearer Securities or Registered Securities, or any
combination thereof, as shall be specified by the beneficial owner thereof, but
subject to the satisfaction of any certification or other requirements to the
issuance of Bearer Securities; provided, however, that no such exchanges may
occur during a period beginning at the opening of business 15 days before any
selection of Securities of the same series to be redeemed and ending on the
relevant Redemption Date; and provided, further, that (unless otherwise provided
in or pursuant to this Indenture) no Bearer Security delivered in exchange for a
portion of a global Security shall be mailed or otherwise delivered to any
location in the United States. Promptly following any such exchange in part,
such global Security shall be returned by the Trustee to such Depository or the
U.S. Depository, as the case may be, or such other Depository or U.S. Depository
referred to above in accordance with the instructions of the Company referred to
above. If a Registered Security is issued in exchange for any portion of a
global Security after the close of business at the Office or Agency for such
Security where such exchange occurs on or after (i) any Regular Record Date for
such Security and before the opening of business at such Office or Agency on the
next succeeding Interest Payment Date, or (ii) any Special Record Date for such
Security and before the opening of business at such Office or Agency on the
related proposed date for payment of interest or Defaulted Interest, as the case
may be, interest shall not be payable on such Interest Payment Date or proposed
date for payment, as the case may be, in respect of such Registered Security,
but shall be payable on such Interest Payment Date or proposed date for payment,
as the case may be, only to the Person to whom interest in respect of such
portion of such global Security shall be payable in accordance with the
provisions of this Indenture.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company and the Guarantor,
respectively, evidencing the same debt and entitling the Holders thereof to the
same benefits under this Indenture as the Securities surrendered upon such
registration of transfer or exchange.

     Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security duly executed by the Holder thereof or his
attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.

     Except as otherwise provided in or pursuant to this Indenture, the Company
shall not be required (i) to issue, register the transfer of or exchange any
Securities during a period beginning at the opening of business 15 days before
the day of mailing of a notice of redemption of Securities of like tenor and the
same series under Section 11.3 and ending at the close of business

                                       35
<PAGE>

on the day of such mailing, or (ii) to register the transfer of or exchange any
Registered Security selected for redemption in whole or in part, except in the
case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security selected for redemption
except, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such
Security not to be so repaid.

     Section 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 3.6, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

     If there be delivered to the Company, the Guarantor and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or Coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company, the Guarantor or the Trustee that such Security or
Coupon has been acquired by a bona fide purchaser, the Company shall execute
and, upon the Company's request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, a
new Security of the same series containing identical terms and of like principal
amount and bearing a number not contemporaneously outstanding, with Coupons
appertaining thereto corresponding to the Coupons, if any, appertaining to such
destroyed, lost or stolen Security or to the Security to which such destroyed,
lost or stolen Coupon appertains.

     Notwithstanding the foregoing provisions of this Section 3.6, in case any
mutilated, destroyed, lost or stolen Security or Coupon has become or is about
to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security or Coupon; provided, however, that payment of
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 10.2, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
any interest on Bearer Securities and any Additional Amounts with respect to
such interest shall be payable only upon presentation and surrender of the
Coupons appertaining thereto.

     Upon the issuance of any new Security under this Section 3.6, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be

                                       36
<PAGE>

imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

     Every new Security, with any Coupons appertaining thereto issued pursuant
to this Section 3.6 in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen Coupon appertains
shall constitute a separate obligation of the Company and the Guarantor, whether
or not the destroyed, lost or stolen Security and Coupons appertaining thereto
or the destroyed, lost or stolen Coupon shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and any
Coupons, if any, duly issued hereunder.

     The provisions of this Section 3.6, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or Coupons.

     Section 3.7. Payment of Interest and Certain Additional Amounts; Rights to
Interest and Certain Additional Amounts Preserved.

     Unless otherwise provided in or pursuant to this Indenture, any interest on
and any Additional Amounts with respect to any Registered Security which shall
be payable, and are punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name such Security (or one or
more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest.

     Unless otherwise provided in or pursuant to this Indenture, any interest on
and any Additional Amounts with respect to any Registered Security which shall
be payable, but shall not be punctually paid or duly provided for, on any
Interest Payment Date for such Registered Security (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest may be paid by the Company or the Guarantor, at its election
in each case, as provided in Clause (1) or (2) below:

          (1)  The Company or the Guarantor, as the case may be, may elect to
     make payment of any Defaulted Interest to the Person in whose name such
     Registered Security (or a Predecessor Security thereof) shall be registered
     at the close of business on a Special Record Date for the payment of such
     Defaulted Interest, which shall be fixed by the Company in the following
     manner.  The Company or the Guarantor, as the case may be, shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on such Registered Security, the Special Record Date therefor and the date
     of the proposed payment, and at the same time the Company or the Guarantor,
     as the case may be, shall deposit with the Trustee an amount of money equal
     to the aggregate amount proposed to be paid in respect of such Defaulted
     Interest or shall make arrangements satisfactory to the Trustee for such
     deposit on or prior to the date of the proposed payment, such money when so
     deposited to be held in trust for the benefit of the Person

                                       37
<PAGE>

     entitled to such Defaulted Interest as in this Clause provided. The Special
     Record Date for the payment of such Defaulted Interest shall be not more
     than 15 days and not less than 10 days prior to the date of the proposed
     payment and not less than 10 days after notification to the Trustee of the
     proposed payment. The Trustee shall, in the name and at the expense of the
     Company or the Guarantor, cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to the Holder of such Registered Security (or
     a Predecessor Security thereof) at his address as it appears in the
     Security Register not less than 10 days prior to such Special Record Date.
     The Trustee may, in its discretion, in the name and at the expense of the
     Company or the Guarantor, cause a similar notice to be published at least
     once in an Authorized Newspaper of general circulation in the Borough of
     Manhattan, The City of New York, but such publication shall not be a
     condition precedent to the establishment of such Special Record Date.
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been mailed as aforesaid, such Defaulted
     Interest shall be paid to the Person in whose name such Registered Security
     (or a Predecessor Security thereof) shall be registered at the close of
     business on such Special Record Date and shall no longer be payable
     pursuant to the following clause (2).

          (2)  The Company or the Guarantor, as the case may be, may make
     payment of any Defaulted Interest in any other lawful manner not
     inconsistent with the requirements of any securities exchange on which such
     Security may be listed, and upon such notice as may be required by such
     exchange, if, after notice given by the Company or the Guarantor, as the
     case may be, to the Trustee of the proposed payment pursuant to this
     Clause, such payment shall be deemed practicable by the Trustee.

     Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the Company or the Guarantor, interest on Registered
Securities that bear interest may be paid by mailing a check to the address of
the Person entitled thereto as such address shall appear in the Security
Register or by transfer to an account maintained by the payee with a bank
located in the United States.

     Subject to the foregoing provisions of this Section and Section 3.5, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

     In the case of any Registered Security of any series that is convertible
into other securities of the Company or exchangeable for securities of the
Guarantor or another issuer, which Registered Security is converted or exchanged
after any Regular Record Date and on or prior to the next succeeding Interest
Payment Date (other than any Registered Security with respect to which the
Stated Maturity is prior to such Interest Payment Date), interest with respect
to which the Stated Maturity is on such Interest Payment Date shall be payable
on such Interest Payment Date notwithstanding such conversion or exchange, and
such interest (whether or not

                                       38
<PAGE>

punctually paid or duly provided for) shall be paid to the Person in whose name
that Registered Security (or one or more predecessor Registered Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Registered Security which is converted or exchanged, interest with
respect to which the Stated Maturity is after the date of conversion or exchange
of such Registered Security shall not be payable.

     Section 3.8. Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Guarantor, the Trustee and any agent of the Company
or the Guarantor or the Trustee may treat the Person in whose name such
Registered Security is registered in the Security Register as the owner of such
Registered Security for the purpose of receiving payment of principal of, any
premium and (subject to Sections 3.5 and 3.7) interest on and any Additional
Amounts with respect to such Registered Security and for all other purposes
whatsoever, whether or not any payment with respect to such Registered Security
shall be overdue, and none of the Company, the Guarantor, the Trustee or any
agent of the Company, the Guarantor or the Trustee shall be affected by notice
to the contrary.

     The Company, the Guarantor, the Trustee and any agent of the Company, the
Guarantor or the Trustee may treat the bearer of any Bearer Security or the
bearer of any Coupon as the absolute owner of such Security or Coupon for the
purpose of receiving payment thereof or on account thereof and for all other
purposes whatsoever, whether or not any payment with respect to such Security or
Coupon shall be overdue, and none of the Company, the Guarantor, the Trustee or
any agent of the Company, the Guarantor or the Trustee shall be affected by
notice to the contrary.

     No Holder of any beneficial interest in any global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository may be treated by the Company, the
Guarantor, the Trustee, and any agent of the Company, the Guarantor or the
Trustee as the owner of such global Security for all purposes whatsoever.  None
of the Company, the Guarantor, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

     Section 3.9. Cancellation.

     All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee.  The Company or the Guarantor may at
any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company or the Guarantor may
have acquired in any manner whatsoever,

                                       39

and all Securities so delivered shall be cancelled promptly by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by or
pursuant to this Indenture. All cancelled Securities and Coupons held by the

Guarantor Order the Company or the Guarantor, as the case may be, directs their
return to it.

     Except as otherwise provided in or pursuant to this Indenture or in any
Security, interest on the Securities shall be computed on the basis of a 360-day

     Section 3.11.  Extension of Interest Payment Period.

     If specified as contemplated by Section 3.1 with respect to the Securities
of a particular series and subject to the terms, conditions and covenants, if
any, so specified, the Company shall have the right, at any time and from time
to time during the term of such series, to defer the payment of interest on such
Securities for such period or periods as may be specified as contemplated by
Section 3.1 (each, an "Extension Period"), during which Extension Periods the
Company shall have the right to make partial payments of interest on any
Interest Payment Date.  No Extension Period shall end on a day other than an
Interest Payment Date.  At the end of any such Extension Period, the Company
shall pay all interest then accrued and unpaid on the Securities (together with
Additional Interest thereon, if any, at the rate specified for the Securities of
such series to the extent permitted by applicable law).  Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that no Extension Period shall exceed the
period or periods specified in such Securities or extend beyond the Stated
Maturity of the principal of such Securities.  Upon termination of any Extension
Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due on any Interest Payment Date, the Company may elect
to begin a new Extension Period, subject to the above requirements.  No interest
shall be due and payable during an Extension Period, except at the end thereof.

     The Company shall give the Holders of the Securities of such series and the
Trustee notice of its election to begin any such Extension Period at least one
Business Day prior to the Interest Payment Date or, with respect to the
Securities of a series issued to an ACE Trust, prior to the earlier of (i) the
date the Distributions on the Preferred Securities of such ACE Trust are payable
or (ii) the date the trustees of such ACE Trust are required to give notice to
any securities exchange or other applicable self-regulatory organization or to
holders of such Preferred Securities of the record date or the date such
Distributions are payable, but in any event not less than one Business Day prior
to such record date.

     The Trustee shall promptly give notice of the Company's election to begin
any such Extension Period to the Holders of the outstanding Securities of such
series.

case may be;

          (2)  the Company or the Guarantor has paid or caused to be paid all
     other sums payable hereunder by the Company and the Guarantor with respect

     Section 4.2.   Defeasance and Covenant Defeasance.

          (1)  Unless pursuant to Section 3.1, either or both of (i) defeasance
     of the Securities of or within a series under clause (2) of this Section
     4.2 shall not be applicable with respect to the Securities of such series
     or (ii) covenant defeasance of the Securities of or within a series under
     clause (3) of this Section 4.2 shall not be applicable with respect to the
     Securities of such series, then such provisions, together with the other
     provisions of this Section 4.2 (with such modifications thereto as may be
     specified pursuant to Section 3.1 with respect to any Securities), shall be
     applicable to such Securities and any Coupons appertaining thereto, and the
     Company may at its option by Board Resolution, at any time, with respect to
     such Securities and any Coupons appertaining thereto, elect to have Section
     4.2(2) or Section 4.2(3) be applied to such Outstanding Securities and any
     Coupons appertaining thereto upon compliance with the conditions set forth
     below in this Section 4.2.

                                       43
<PAGE>

          (2)  Upon the Company's exercise of the above option applicable to
     this Section 4.2(2) with respect to any Securities of or within a series,
     the Company and the Guarantor shall be deemed to have been discharged from
     its obligations with respect to such Outstanding Securities and any Coupons
     appertaining thereto and under the Guarantee in respect thereof,
     respectively, on the date the conditions set forth in clause (4) of this
     Section 4.2 are satisfied (hereinafter, "defeasance"). For this purpose,
     such defeasance means that the Company or the Guarantor shall be deemed to
     have paid and discharged the entire Indebtedness represented by such
     Outstanding Securities and any Coupons appertaining thereto, and under the
     Guarantee in respect thereof, which shall thereafter be deemed to be
     "Outstanding" only for the purposes of clause (5) of this Section 4.2 and
     the other Sections of this Indenture referred to in clauses (i) and (ii)
     below, and to have satisfied all of its other obligations under such
     Securities and any Coupons appertaining thereto, and under the Guarantee in
     respect thereof, and this Indenture insofar as such Securities and any
     Coupons appertaining thereto, and the Guarantee in respect thereof, are
     concerned (and the Trustee, at the expense of the Company and the
     Guarantor, shall execute proper instruments acknowledging the same), except
     for the following which shall survive until otherwise terminated or
     discharged hereunder: (i) the rights of Holders of such Outstanding
     Securities and any Coupons appertaining thereto to receive, solely from the
     trust fund described in clause (4) of this Section 4.2 and as more fully
     set forth in such clause, payments in respect of the principal of (and
     premium, if any) and interest (including any Additional Interest), if any,
     on, and Additional Amounts, if any, with respect to, such Securities and
     any Coupons appertaining thereto when such payments are due, and any rights
     of such Holder to convert such Securities into other securities of the
     Company or exchange such Securities for securities of the Guarantor or
     another issuer, (ii) the obligations of the Company, the Guarantor and the
     Trustee with respect to such Securities under Sections 3.5, 3.6, 10.2 and
     10.3 and with respect to the payment of Additional Amounts, if any, on such
     Securities as contemplated by Sections 10.4 and 17.2 (but only to the
     extent that the Additional Amounts payable with respect to such Securities
     exceed the amount deposited in respect of such Additional Amounts pursuant
     to Section 4.2(4)(a) below), and with respect to any rights to convert such
     Securities into other securities of the Company or exchange such Securities
     for securities of the Guarantor or another issuer, (iii) the rights,
     powers, trusts, duties and immunities of the Trustee hereunder and (iv)
     this Section 4.2. The Company may exercise its option under this Section
     4.2(2) notwithstanding the prior exercise of its option under clause (3) of
     this Section 4.2 with respect to such Securities and any Coupons
     appertaining thereto.

          (3)  Upon the Company's exercise of the option to have this Section
     4.2(3) apply with respect to any Securities of or within a series, the
     Company and the Guarantor shall be released from their obligations under
     any covenant applicable to such Securities specified pursuant to Section
     3.1(20), with respect to such Outstanding Securities and any Coupons
     appertaining thereto, and the Guarantee in respect thereof, on and after
     the date the conditions set forth in clause (4) of this Section 4.2 are
     satisfied (hereinafter, "covenant defeasance"), and such Securities and any
     Coupons appertaining thereto shall

                                       44
<PAGE>

     thereafter be deemed to be not "Outstanding" for the purposes of any
     direction, waiver, consent or declaration or Act of Holders (and the
     consequences of any thereof) in connection with any such covenant, but
     shall continue to be deemed "Outstanding" for all other purposes hereunder.
     For this purpose, such covenant defeasance means that, with respect to such
     Outstanding Securities and any Coupons appertaining thereto, the Company
     and the Guarantor may omit to comply with, and shall have no liability in
     respect of, any term, condition or limitation set forth in any such Section
     or such other covenant, whether directly or indirectly, by reason of any
     reference elsewhere herein to any such Section or such other covenant or by
     reason of reference in any such Section or such other covenant to any other
     provision herein or in any other document and such omission to comply shall
     not constitute a default or an Event of Default under Section 5.1(4) or
     5.1(8) or otherwise, as the case may be, but, except as specified above,
     the remainder of this Indenture and such Securities and Coupons
     appertaining thereto and the Guarantee in respect thereof shall be
     unaffected thereby.

          (4)  The following shall be the conditions to application of clause
     (2) or (3) of this Section 4.2 to any Outstanding Securities of or within a
     series and any Coupons appertaining thereto and the Guarantee in respect
     thereof:

               (a)  The Company or the Guarantor shall irrevocably have
          deposited or caused to be deposited with the Trustee (or another
          trustee satisfying the requirements of Section 6.7 who shall agree to
          comply with the provisions of this Section 4.2 applicable to it) as
          trust funds in trust for the purpose of making the following payments,
          specifically pledged as security for, and dedicated solely to, the
          benefit of the Holders of such Securities and any Coupons appertaining
          thereto, (1) an amount in Dollars or in such Foreign Currency in which
          such Securities and any Coupons appertaining thereto are then
          specified as payable at Stated Maturity, or (2) Government Obligations
          applicable to such Securities and Coupons appertaining thereto
          (determined on the basis of the Currency in which such Securities and
          Coupons appertaining thereto are then specified as payable at Stated
          Maturity) which through the scheduled payment of principal and
          interest in respect thereof in accordance with their terms will
          provide, not later than one day before the due date of any payment of
          principal of (and premium, if any) and interest (including any
          Additional Interest), if any, on such Securities and any Coupons
          appertaining thereto, money in an amount, or (3) a combination
          thereof, in any case, in an amount, sufficient, without consideration
          of any reinvestment of such principal and interest, in the opinion of
          a nationally recognized firm of independent public accountants
          expressed in a written certification thereof delivered to the Trustee,
          to pay and discharge, and which shall be applied by the Trustee (or
          other qualifying trustee) to pay and discharge, (y) the principal of
          (and premium, if any) and interest (including any Additional
          Interest), if any, on such Outstanding Securities and any Coupons
          appertaining thereto at the Stated Maturity of such principal or
          installment of principal or premium or interest and (z) any mandatory
          sinking fund payments or analogous payments applicable to

                                       45
<PAGE>

          such Outstanding Securities and any Coupons appertaining thereto on
          the days on which such payments are due and payable in accordance with
          the terms of this Indenture and of such Securities and any Coupons
          appertaining thereto.

               (b)  Such defeasance or covenant defeasance shall not result in a
          breach or violation of, or constitute a default under, this Indenture
          or any other material agreement or instrument to which the Company or
          the Guarantor is a party or by which either of them is bound.

               (c)  No Event of Default or event which with notice or lapse of
          time or both would become an Event of Default with respect to such
          Securities and any Coupons appertaining thereto shall have occurred
          and be continuing on the date of such deposit and, with respect to
          defeasance only, at any time during the period ending on the 123rd day
          after the date of such deposit (it being understood that this
          condition shall not be deemed satisfied until the expiration of such
          period).

               (d)  In the case of an election under clause (2) of this Section
          4.2, the Company or the Guarantor shall have delivered to the Trustee
          an Opinion of Counsel stating that (i) the Company or the Guarantor
          has received from the Internal Revenue Service a letter ruling, or
          there has been published by the Internal Revenue Service a Revenue
          Ruling, or (ii) since the date of execution of this Indenture, there
          has been a change in the applicable Federal income tax law, in either
          case to the effect that, and based thereon such opinion shall confirm
          that, the Holders of such Outstanding Securities and any Coupons
          appertaining thereto will not recognize income, gain or loss for
          Federal income tax purposes as a result of such defeasance and will be
          subject to Federal income tax on the same amounts, in the same manner
          and at the same times as would have been the case if such defeasance
          had not occurred.

               (e)  In the case of an election under clause (3) of this Section
          4.2, the Company or the Guarantor shall have delivered to the Trustee
          an Opinion of Counsel to the effect that the Holders of such
          Outstanding Securities and any Coupons appertaining thereto will not
          recognize income, gain or loss for Federal income tax purposes as a
          result of such covenant defeasance and will be subject to Federal
          income tax on the same amounts, in the same manner and at the same
          times as would have been the case if such covenant defeasance had not
          occurred.

               (f)  The Company or the Guarantor  shall have delivered to the
          Trustee an Opinion of Counsel to the effect that, after the 123rd day
          after the date of deposit, all money and Government Obligations (or
          other property as may be provided pursuant to Section 3.1) (including
          the proceeds thereof) deposited or caused to be deposited with the
          Trustee (or other qualifying trustee) pursuant to this clause (4) to
          be held in trust will not be subject to any case or proceeding
          (whether voluntary or involuntary) in respect of the Company or the
          Guarantor under any Federal or State bankruptcy, insolvency,
          reorganization or other similar

               (g)  The Company and the Guarantor shall have delivered to the
          Trustee an Officer's Certificate and a Guarantor's Officer's
          Certificate and the Company or the Guarantor shall have delivered to
          the Trustee an Opinion of Counsel, each stating that all conditions
          precedent to the defeasance or covenant defeasance under clause (2) or
          (3) of this Section 4.2 (as the case may be) have been complied with.

               (h)  Notwithstanding any other provisions of this Section 4.2(4),
          such defeasance or covenant defeasance shall be effected in compliance
          with any additional or substitute terms, conditions or limitations
          which may be imposed on the Company or the Guarantor in connection
          therewith pursuant to Section 3.1.

          (5)  Unless otherwise specified in or pursuant to this Indenture or
     any Security, if, after a deposit referred to in Section 4.2(4)(a) has been
     made, (a) the Holder of a Security in respect of which such deposit was
     made is entitled to, and does, elect pursuant to Section 3.1 or the terms
     of such Security to receive payment in a Currency other than that in which
     the deposit pursuant to Section 4.2(4)(a) has been made in respect of such
     Security, or (b) a Conversion Event occurs in respect of the Foreign
     Currency in which the deposit pursuant to Section 4.2(4)(a) has been made,
     the indebtedness represented by such Security and any Coupons appertaining
     thereto shall be deemed to have been, and will be, fully discharged and
     satisfied through the payment of the principal of (and premium, if any),

     specified below in the case of any such election) the amount or other
     property deposited in respect of such Security into the Currency in which
     such Security becomes payable as a result of such election or Conversion

     Event.

     The Company and the Guarantor (without duplication) shall pay and indemnify
the Trustee (or other qualifying trustee, collectively for purposes of this
Section 4.2(5) and Section 4.3, the "Trustee") against any tax, fee or other
charge, imposed on or assessed against the Government Obligations deposited
pursuant to this Section 4.2 or the principal or interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

shall deliver or pay to the Company from time to time upon Company Request, or
the Guarantor upon Guarantor Request, as the case may be, any money or

     Section 5.2.   Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the time
Outstanding (other than an Event of Default specified in clause (7) or (8) of
Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due

                                       50
<PAGE>

and payable immediately, by a notice in writing to the Company and the Guarantor
(and to the Trustee if given by the Holders), and upon any such declaration such
principal or such lesser amount shall become immediately due and payable;
provided that, in the case of Securities of a series issued to an ACE Trust, if,
upon an Event of Default, the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of such series fail to declare
the principal of all the Securities of such series, or such lesser amount as may
be provided for in the Securities of such series, to be immediately due and
payable, the holders of at least 25% in liquidation amount of the Preferred
Securities of such ACE Trust then outstanding shall have such right by a notice
in writing to the Company, the Guarantor, the Trustee and the Property Trustee;
and upon any such declaration such principal or such lesser amount and all
accrued and unpaid interest (including any Additional Interest) thereon shall
become immediately due and payable, provided that the payment of principal and
interest and all other amounts due with respect to such Securities shall remain
subordinated to the extent provided in Article 16.

     If an Event of Default specified in clause (7) or (8) of Section 5.1
occurs, all unpaid principal of and accrued interest (including any Additional
Interest) on the Outstanding Securities of that series (or such lesser amount as
may be provided for in the Securities of such series) shall ipso facto become
and be immediately due and payable without any declaration or other act on the
part of the Trustee or any Holder of any Security of that series.

     At any time after a declaration of acceleration with respect to the
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series (subject to, in the case of any series
of Securities held as assets of an ACE Trust, such consent of the holders of the
Preferred Securities and the Common Securities of such ACE Trust as may be
required under the Trust Agreement of such ACE Trust), by written notice to the
Company, the Guarantor and the Trustee, may rescind and annul such declaration
and its consequences if

          (1)  the Company or the Guarantor has paid or deposited with the
     Trustee a sum of money sufficient to pay

               (a)  all overdue installments of any interest (including any
          Additional Interest) on and Additional Amounts with respect to all
          Securities of such series and any Coupon appertaining thereto,

               (b)  the principal of and any premium on any Securities of such
          series which have become due otherwise than by such declaration of
          acceleration and interest thereon and any Additional Amounts with
          respect thereto at the rate or rates borne by or provided for in such
          Securities,

               (c)  to the extent that payment of such interest or Additional
          Amounts is lawful, interest upon overdue installments of any interest
          and Additional Amounts at the rate or rates borne by or provided for
          in such Securities, and

                                       51
<PAGE>

               (d)  all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel and all other amounts due the Trustee
          under Section 6.6; and

          (2)  all Events of Default with respect to Securities of such series,
     other than the non-payment of the principal of, any premium and interest
     on, and any Additional Amounts with respect to Securities of such series
     which shall have become due solely by such declaration of acceleration,
     shall have been cured or waived as provided in Section 5.13.

     In the case of Securities of a series issued to an ACE Trust, should the
Holder of such Securities fail to rescind and annul such declaration and its
consequences, the holders of a majority in liquidation amount of the Preferred
Securities of such ACE Trust then outstanding shall have such right by written
notice to the Company, the Guarantor, the Trustee and the Property Trustee,
subject to satisfaction of the conditions set forth in clauses (1) and (2) above
of this Section 5.2.

     No such rescission shall affect any subsequent default or impair any right
consequent thereon.

Trustee.

     The Company and the Guarantor each covenants, in each case, that if

          (1)  default is made in the payment of any installment of interest
     (including any Additional Interest) on or any Additional Amounts with
     respect to any Security or any Coupon appertaining thereto when such
     interest or Additional Amounts shall have become due and payable and such
     default continues for a period of 30 days, or

          (2)  default is made in the payment of the principal of or any premium
     on any Security or any Additional Amounts with respect thereto at their
     Maturity,

the Company or the Guarantor, as the case may be, shall, upon demand of the
Trustee, pay to the Trustee, for the benefit of the Holders of such Securities
and any Coupons appertaining thereto, the whole amount of money then due and
payable with respect to such Securities and any Coupons appertaining thereto,
with interest (including any Additional Interest) upon the overdue principal,
any premium and (to the extent that payment of such interest shall be legally
enforceable and, if the Securities are held by an ACE Trust, without duplication
of any other amounts paid to such ACE Trust in respect thereof) upon any overdue
installments of interest and Additional Amounts at the rate or rates borne by or
provided for in such Securities, and, in addition thereto, such further amount
of money as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel and all other amounts due to the Trustee
under Section 6.6.

<PAGE>

     If the Company or the Guarantor fails to pay the money it is required to
pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of
the Trustee, the Trustee, in its own name and as trustee of an express trust,
may institute a judicial proceeding for the collection of the money so due and
unpaid, and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Company or the Guarantor or any other obligor upon
such Securities and any Coupons appertaining thereto and collect the monies
adjudged or decreed to be payable in the manner provided by law out of the
property of the Company or the Guarantor or any other obligor upon such
Securities and any Coupons appertaining thereto, wherever situated.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
Coupons appertaining thereto by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

     Section 5.4.   Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company, the Guarantor or any other obligor
upon the Securities of any series or the property of the Company, the Guarantor
or such other obligor or their creditors, the Trustee (irrespective of whether
the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company or the Guarantor for the payment of
any overdue principal, premium, interest (including any Additional Interest) or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

          (1)  to file and prove a claim for the whole amount, or such lesser
     amount as may be provided for in the Securities of any applicable series,
     of the principal and any premium, interest (including any Additional
     Interest) and Additional Amounts owing and unpaid in respect of the
     Securities and any Coupons appertaining thereto and to file such other
     papers or documents as may be necessary or advisable in order to have the
     claims of the Trustee (including any claim for the reasonable compensation,
     expenses, disbursements and advances of the Trustee, its agents or counsel)
     and of the Holders of Securities or any Coupons appertaining thereto
     allowed in such judicial proceeding, and

          (2)  to collect and receive any monies or other property payable or
     deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities or any Coupons to make such payments to the Trustee
and, in the event that the Trustee shall consent to the

                                       53
<PAGE>

making of such payments directly to the Holders of Securities or any Coupons, to
pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel and
any other amounts due the Trustee under Section 6.6.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or any Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or any Coupon in any such proceeding.

     Section 5.5.   Trustee May Enforce Claims without Possession of Securities
or Coupons.

     All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of the
Securities or Coupons in respect of which such judgment has been recovered.

     Securities and any Coupons for principal and any premium, interest and
     Additional Amounts in respect of which or for the benefit of which such
     money has been collected, ratably, without preference or priority of any
     kind, according to the aggregate amounts due and payable on such Securities
     and Coupons for principal and any premium, interest (including any

     Section 5.7.   Limitations on Suits.

     No Holder of any Security of any series or any Coupons appertaining thereto
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless

          (1)  such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Securities of such
     series;

          (2)  the Holders of not less than 25% in principal amount of the
     Outstanding Securities of such series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

          (3)  such Holder or Holders have offered to the Trustee such indemnity
     as is reasonably satisfactory to it against the costs, expenses and
     liabilities to be incurred in compliance with such request;

          (4)  the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and

          (5)  no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in principal amount of the Outstanding Securities of such series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, or to
obtain or to seek to obtain priority or preference over any other Holders or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.

Premium, Interest and Additional Amounts.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of, any premium and (subject to Sections 3.5,
3.7 and 3.11) interest (including any Additional Interest) on, and any
Additional Amounts with respect to such Security or payment of such Coupon, as
the case may be, on the respective Stated Maturity or Maturities therefor
specified in such Security or Coupon (or, in the case of redemption, on the
Redemption Date or, in the case of repayment at the option of such Holder if
provided in or pursuant to this Indenture, on the date such repayment is due)
and to institute suit for the enforcement of any such payment, and such right
shall not be impaired without the consent of such Holder.  In the case of
Securities of a series issued to an ACE Trust, any holder of Preferred
Securities issued by such ACE Trust shall have the right, upon the occurrence of
an Event of Default described in Section 5.1(1) or

                                       55

principal of, and any premium and (subject to Sections 3.5, 3.7 and 3.11)
interest (including any Additional Interest) on, and Additional Amounts with
respect to, such Securities having a principal amount equal to the liquidation
amount of such Preferred Securities held by such holder (a "Direct Action").
Notwithstanding any payments made to a holder of Preferred Securities by the
Company or the Guarantor in connection with a Direct Action, the Company and the
Guarantor shall remain obligated to pay the principal of and premium, if any, or
interest on and Additional Amounts, if any, with respect to the related
Securities, and the Company or the Guarantor shall be subrogated to the rights

Guarantor, as the case may be, to such holder in any Direct Action.

     Section 5.9.   Restoration of Rights and Remedies.

     If the Trustee or any Holder of a Security or a Coupon has, or the holders
of Preferred Securities have, instituted any proceeding to enforce any right or
remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee, to
such Holder or to the holders of such Preferred Securities, then and in every
such case the Company, the Guarantor, the Trustee and each such Holder or the
holders of such Preferred Securities shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and each such
Holder or the holders of such Preferred Securities shall continue as though no
such proceeding had been instituted.

     Section 5.10.  Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph
of Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee, to each and every Holder of a Security or a Coupon or to the holders of
Preferred Securities is intended to be exclusive of any other right or remedy,
and every right and remedy, to the extent permitted by law, shall be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not, to the
extent permitted by law, prevent the concurrent assertion or employment of any
other appropriate right or remedy.

     Section 5.11.  Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security or
Coupon or of the holders of Preferred Securities to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to any
Holder of a Security or a Coupon or to the holders of Preferred Securities may

                                       56
<PAGE>

be exercised from time to time, and as often as may be deemed expedient, by the
Trustee, by such Holder or by such holders of Preferred Securities, as the case
may be.

     Section 5.12.  Control by Holders of Securities.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee with respect to the Securities of
such series and any Coupons appertaining thereto, provided that

          (1)  such direction shall not be in conflict with any rule of law or
     with this Indenture or with the Securities of such series,

          (2)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction, and

          (3)  such direction is not unduly prejudicial to the rights of the
     other Holders of Securities of such series not joining in such action.

     Section 5.13.  Waiver of Past Defaults.

Outstanding Securities of any series on behalf of the Holders of all the

majority in liquidation amount of the Preferred Securities issued by such ACE
Trust then outstanding, may waive any past default hereunder with respect to
such series and its consequences, except a default

          (1)  in the payment of the principal of, any premium or interest
     (including any Additional Interest) on, or any Additional Amounts with
     respect to, any Security of such series or any Coupons appertaining

          (2)  in respect of a covenant or provision hereof which under Article
     9 cannot be modified or amended without the consent of the Holder of each
     Outstanding Security of such series affected.

     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

     Section 5.14.  Waiver of Usury, Stay or Extension Laws.

     The Company and the Guarantor each covenants that (to the extent that it
may lawfully do so) it will not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any usury, stay or
extension law wherever enacted, now or at any time

                                       57

hereafter in force, which may affect the covenants or the performance of this
Indenture; and the Company and the Guarantor each expressly waives (to the
extent that it may lawfully do so) all benefit or advantage of any such law and
covenants that it will not hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted.

     Section 5.15.  Undertaking for Costs

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 5.15 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series or, if
a series of Securities is held by an ACE Trust, the holders of more than 10% in
liquidation amount of the Preferred Securities of that ACE Trust then
outstanding, or to any suit instituted by any Holder or any holder of Preferred
Securities for the enforcement of the payment of the principal of (or premium,
if any) or interest (including any Additional Interest), if any, on or
Additional Amounts, if any, with respect to any Security on or after the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date, and, in the case of repayment, on
or after the date for repayment) or for the enforcement of the right, if any, to
convert or exchange any Security into other securities in accordance with its
terms.

Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the best interest of the Holders of Securities and Coupons
of such series; and provided, further, that in the case of any default of the
character specified in Section 5.1(5) with respect to Securities of such series,
no such notice to Holders shall be given until at least 30 days after the

certificate of authentication, and in any Coupons shall be taken as the
statements of the Company or the Guarantor, as the case may be, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness.  The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities or the Coupons, except that

                                       60
<PAGE>

and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may

have if it were not the Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other Person.

     Section 6.5.   Money Held in Trust.

     Except as provided in Section 4.3 and Section 10.3, money held by the
Trustee in trust hereunder need not be segregated from other funds except to the

     The Company and the Guarantor (without duplication) each agree:

          (1)  to pay to the Trustee from time to time reasonable compensation
     for all services rendered by the Trustee hereunder (which compensation
     shall not be limited by any provision of law in regard to the compensation
     of a trustee of an express trust);

          (2)  except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision

     employees for, and to hold them harmless against, any loss, liability or
     expense incurred without negligence or bad faith on their part, arising out
     of or in connection with the acceptance or administration of the trust or
     trusts hereunder, including the costs and expenses of defending themselves
     against any claim or liability in connection with the exercise or
     performance of any of their powers or duties hereunder, except to the
     extent that any such loss, liability or expense was due to the Trustee's
     negligence or bad faith.

     As security for the performance of the obligations of the Company and the
Guarantor under this Section, the Trustee shall have a lien prior to the
Securities of any series upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the payment of principal of, and
premium or interest (including any Additional Interest) on or any Additional
Amounts with respect to Securities or any Coupons appertaining thereto.

constitute an expense of administration under any then applicable bankruptcy or
insolvency law.  "Trustee" for purposes

bad faith of any Trustee shall not affect the rights of any other Trustee under
this Section 6.6.

     the Guarantor.  If the instrument of acceptance by a successor Trustee

     30 days after the giving of such notice of resignation, the resigning
     Trustee may petition any court of competent jurisdiction for the
     appointment of a successor Trustee with respect to such series.

          (3)  The Trustee may be removed at any time with respect to the
     Securities of any series by Act of the Holders of a majority in principal

          himself and all others similarly situated, petition any court of
          competent jurisdiction for the removal of the Trustee with respect to
          all Securities of such series and the appointment of a successor
          Trustee or Trustees.

     acting, or if a vacancy shall occur in the office of Trustee for any cause,
     with respect to the Securities of one or more series, the Company, by or
     pursuant to a Board Resolution, and the Guarantor, by or pursuant to a
     Guarantor's Board Resolution, shall promptly appoint a successor Trustee or
     Trustees with respect to the Securities of such series (it being understood
     that any such successor Trustee may be appointed with respect to the

     occurrence of such vacancy, a successor Trustee with respect to the
     Securities of any series shall be appointed by Act of the Holders of a
     majority in principal amount of the Outstanding Securities of such series
     delivered to the Company, the Guarantor and the retiring Trustee, the
     successor Trustee so appointed shall, forthwith upon its acceptance of such
     appointment in accordance with the applicable requirements of Section 6.9,
     become the successor Trustee with respect to the Securities of such series
     and to that extent supersede the successor Trustee appointed by the Company
     and the Guarantor.  If no successor Trustee with respect to the Securities
     of any series shall have been so appointed by the Company and the Guarantor
     or the Holders of Securities and accepted appointment in the manner
     required by Section 6.9, any Holder of a Security who has been a bona fide
     Holder of a Security of such series for at least six months may, on behalf
     of himself and all others similarly situated, petition any court of
     competent jurisdiction for the appointment of a successor Trustee with
     respect to the Securities of such series.

     Registered Securities, if any, of such series as their names and addresses
     appear in the Security Register and, if Securities of such series are
     issued as Bearer Securities, by publishing notice of such event once in an
     Authorized Newspaper in each Place of Payment located outside the United
     States. Each notice shall include the name of the successor Trustee with
     respect to the Securities of such series and the address of its Corporate
     Trust Office.

          (7)  In no event shall any retiring Trustee be liable for the acts or
     omissions of any successor Trustee hereunder.

     Section 6.9.   Acceptance of Appointment by Successor.

          (1)  Upon the appointment hereunder of any successor Trustee with
     respect to all Securities, such successor Trustee so appointed shall
     execute, acknowledge and deliver to the Company, the Guarantor and the
     retiring Trustee an instrument accepting such appointment, and thereupon
     the resignation or removal of the retiring Trustee shall become effective
     and such successor Trustee, without any further act, deed or conveyance,
     shall become vested with all the rights, powers, trusts and duties
     hereunder of the retiring Trustee; but, on the request of the Company, the
     Guarantor or such successor Trustee, such retiring Trustee, upon payment of
     its charges, shall execute and deliver an instrument transferring to such
     successor Trustee all the rights, powers and trusts of the retiring Trustee
     and, subject to Section 10.3, shall duly assign, transfer and deliver to
     such successor Trustee all property and money held by such retiring Trustee
     hereunder, subject nevertheless to its claim, if any, provided for in
     Section 6.6.

     respect to the Securities of one or more (but not all) series, the Company,
     the Guarantor, the retiring Trustee and such successor Trustee shall
     execute and deliver an indenture supplemental hereto wherein each successor
     Trustee shall accept such appointment and which (1) shall contain such
     provisions as shall be necessary or desirable to transfer and confirm to,
     and to vest in, such successor Trustee all the rights, powers, trusts and
     duties of the retiring Trustee with respect to the Securities of that or
     those series to which the appointment of such successor Trustee relates,

     retiring Trustee, and (3) shall add to or change any of the provisions of
     this Indenture as shall be necessary to provide for or facilitate the
     administration of the trusts hereunder by more than one Trustee, it being
     understood that nothing herein or in such supplemental indenture shall
     constitute such Trustees co-trustees of the same trust, that each such
     Trustee shall be trustee of a trust or trusts hereunder separate and apart
     from any trust or trusts hereunder administered by any other such Trustee
     and that no Trustee shall be responsible for any notice given to, or
     received by, or any act or failure to act on the part of any other Trustee
     hereunder, and, upon the

                                       64

     removal of the retiring Trustee shall become effective to the extent
     provided therein, such retiring Trustee shall have no further
     responsibility for the exercise of rights and powers or for the performance
     of the duties and obligations vested in the Trustee under this Indenture
     with respect to the Securities of that or those series to which the
     appointment of such successor Trustee relates other than as hereinafter
     expressly set forth, and such successor Trustee, without any further act,
     deed or conveyance, shall become vested with all the rights, powers, trusts
     and duties of the retiring Trustee with respect to the Securities of that
     or those series to which the appointment of such successor Trustee relates;
     but, on request of the Company, the Guarantor or such successor Trustee,
     such retiring Trustee, upon payment of its charges with respect to the
     Securities of that or those series to which the appointment of such
     successor Trustee relates and subject to Section 10.3 shall duly assign,
     transfer and deliver to such successor Trustee, to the extent contemplated
     by such supplemental indenture, the property and money held by such
     retiring Trustee hereunder with respect to the Securities of that or those
     series to which the appointment of such successor Trustee relates, subject
     to its claim, if any, provided for in Section 6.6.

          (3)  Upon request of any Person appointed hereunder as a successor
     Trustee, the Company and the Guarantor shall execute any and all
     instruments for more fully and certainly vesting in and confirming to such
     successor Trustee all such rights, powers and trusts referred to in
     paragraph (1) or (2) of this Section, as the case may be.

          (4)  No Person shall accept its appointment hereunder as a successor
     Trustee unless at the time of such acceptance such successor Person shall
     be qualified and eligible under this Article.

     Any Corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, shall be the
successor of the Trustee hereunder, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.  In case any
Securities shall have been authenticated but not delivered by the Trustee then
in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

     Section 6.11.  Appointment of Authenticating Agent.

     The Trustee may appoint one or more Authenticating Agents acceptable to the
Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment or pursuant to Section 3.6, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder.  Wherever reference is

                                       65

made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.

     Each Authenticating Agent must be acceptable to the Company and the
Guarantor and, except as provided in or pursuant to this Indenture, shall at all
times be a corporation that would be permitted by the Trust Indenture Act to act
as trustee under an indenture qualified under the Trust Indenture Act, is
authorized under applicable law and by its charter to act as an Authenticating
Agent and has a combined capital and surplus (computed in accordance with

     Section 9.3.   Execution of Supplemental Indentures.

     As a condition to executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 315 of the Trust Indenture Act) shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture and an
Officer's Certificate and Guarantor's Officer's Certificate stating that all
conditions precedent to the execution of such supplemental indenture have been
fulfilled.  The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

     Section 9.6.   Conformity with Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

     Section 9.7.   Effect on Senior Indebtedness.

     No supplemental indenture shall directly or indirectly modify or eliminate
the provisions of Article 16 or Article 18, as the case may be, in any manner
which might terminate or impair the subordination of the Securities of any
series to Company Senior Indebtedness with respect to such series or the
subordination of the Guarantee in respect thereof to Guarantor Senior
Indebtedness with respect to such series, respectively, without the prior
written consent of the holders of such Company Senior Indebtedness or Guarantor
Senior Indebtedness, respectively.

     Section 9.8.   Notice of Supplemental Indenture.

     Promptly after the execution by the Company, the Guarantor and the Trustee
of any supplemental indenture pursuant to Section 9.2, the Company shall
transmit to the Holders of Outstanding Securities of any series affected thereby
a notice setting forth the substance of such supplemental indenture.

                                  ARTICLE 10

                                   Covenants

     Section 10.1.  Payment of Principal, any Premium, Interest and Additional
Amounts.

     The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest (including any Additional Interest) on and any
Additional Amounts with respect to the Securities of such series in accordance
with the terms thereof, any Coupons appertaining thereto and this Indenture.
Any interest due on any Bearer Security on or before the Maturity thereof, and
any

                                       76
<PAGE>

Additional Amounts payable with respect to such interest, shall be payable only
upon presentation and surrender of the Coupons appertaining thereto for such
interest as they severally mature.

     Section 10.2.  Maintenance of Office or Agency.

     The Company and the Guarantor shall maintain in each Place of Payment for
any series of Securities an Office or Agency where Securities of such series
(but not Bearer Securities, except as otherwise provided below, unless such
Place of Payment is located outside the United States) may be presented or
surrendered for payment, where Securities of such series may be surrendered for
registration of transfer or exchange, where Securities of such series that are
convertible or exchangeable may be surrendered for conversion or exchange, and
where notices and demands to or upon the Company or the Guarantor in respect of
the Securities of such series relating thereto and this Indenture may be served.
If Securities of a series are issuable as Bearer Securities, the Company and the
Guarantor shall maintain, subject to any laws or regulations applicable thereto,
an Office or Agency in a Place of Payment for such series which is located
outside the United States where Securities of such series and any Coupons
appertaining thereto may be presented and surrendered for payment; provided,
however, that if the Securities of such series are listed on The Stock Exchange
of the United Kingdom and the Republic of Ireland or the Luxembourg Stock
Exchange or any other stock exchange located outside the United States and such
stock exchange shall so require, the Company and the Guarantor shall maintain a
Paying Agent in London, Luxembourg or any other required city located outside
the United States, as the case may be, so long as the Securities of such series
are listed on such exchange.  The Company and the Guarantor will give prompt
written notice to the Trustee of the location, and any change in the location,
of such Office or Agency.  If at any time the Company or the Guarantor shall
fail to maintain any such required Office or Agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee,
except that Bearer Securities of such series and any Coupons appertaining
thereto may be presented and surrendered for payment at the place specified for
the purpose with respect to such Securities as provided in or pursuant to this
Indenture, and the Company and the Guarantor hereby appoint the Trustee as their
agent to receive all such presentations, surrenders, notices and demands.

     Except as otherwise provided in or pursuant to this Indenture, no payment
of principal, premium, interest or Additional Amounts with respect to Bearer
Securities shall be made at any Office or Agency in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company and the Guarantor
in the Borough of Manhattan, The City of New York, if (but only if) payment of
the full amount of such principal, premium, interest or Additional Amounts at
all offices outside the United States maintained for such purpose by the

                                       77
<PAGE>

Company and the Guarantor in accordance with this Indenture is illegal or
effectively precluded by exchange controls or other similar restrictions.

     The Company and the Guarantor may also from time to time designate one or
more other Offices or Agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company or the Guarantor of its
obligation to maintain an Office or Agency in each Place of Payment for
Securities of any series for such purposes.  The Company and the Guarantor shall
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other Office or Agency.  Unless
otherwise provided in or pursuant to this Indenture, the Company and the
Guarantor hereby designate as the Place of Payment for each series of Securities
the Borough of Manhattan, The City of New York, and initially appoint the
Corporate Trust Office of the Trustee as the Office or Agency of the Company in
the Borough of Manhattan, The City of New York for such purpose.  The Company
and the Guarantor may subsequently appoint a different Office or Agency in the
Borough of Manhattan, The City of New York for the Securities of any series.

     Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

     Section 10.3.  Money for Securities Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent, or if the
Guarantor shall act as Paying Agent, with respect to any series of Securities,
it shall, on or before each due date of the principal of, any premium or
interest (including any Additional Interest) on or Additional Amounts with
respect to any of the Securities of such series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay the principal
or any premium, interest (including any Additional Interest) or Additional
Amounts so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided, and shall promptly notify the Trustee
of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it shall, on or prior to each due date of the principal of, any
premium or interest (including any Additional Interest) on or any Additional
Amounts with respect to any Securities of such series, deposit with any Paying
Agent a sum (in the currency or currencies, currency unit or units or composite
currency or currencies described in the preceding paragraph) sufficient to pay
the principal or any premium, interest (including any Additional Interest) or
Additional Amounts so becoming due, such sum to be held in trust for the benefit
of the Persons entitled

                                       78
<PAGE>

thereto, and (unless such Paying Agent is the Trustee) the Company will promptly
notify the Trustee of its action or failure so to act.

     The Company shall cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent shall:

          (1)  hold all sums held by it for the payment of the principal of, any
     premium or interest (including any Additional Interest) on or any
     Additional Amounts with respect to Securities of such series in trust for
     the benefit of the Persons entitled thereto until such sums shall be paid
     to such Persons or otherwise disposed of as provided in or pursuant to this
     Indenture;

          (2)  give the Trustee notice of any default by the Company or the
     Guarantor (or any other obligor upon the Securities of such series) in the
     making of any payment of principal, any premium or interest (including any
     Additional Interest) on or any Additional Amounts with respect to the
     Securities of such series; and

          (3)  at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

     The Company or the Guarantor may at any time, for the purpose of obtaining
the satisfaction and discharge of this Indenture or for any other purpose, pay,
or by Company Order or Guarantor Order direct any Paying Agent to pay, to the
Trustee all sums held in trust by the Company, the Guarantor or such Paying
Agent, such sums to be held by the Trustee upon the same terms as those upon
which such sums were held by the Company, the Guarantor or such Paying Agent;
and, upon such payment by any Paying Agent to the Trustee, such Paying Agent
shall be released from all further liability with respect to such sums.

     Except as otherwise provided herein or pursuant hereto, any money deposited
with the Trustee or any Paying Agent, or then held by the Company or the
Guarantor, in trust for the payment of the principal of, any premium or interest
(including any Additional Interest) on or any Additional Amounts with respect to
any Security of any series or any Coupon appertaining thereto and remaining
unclaimed for two years after such principal or any such premium or interest or
any such Additional Amounts shall have become due and payable shall be paid to
the Company on Company Request (or if deposited by the Guarantor, paid to the
Guarantor on Guarantor Request), or (if then held by the Company or the
Guarantor) shall be discharged from such trust; and the Holder of such Security
or any Coupon appertaining thereto shall thereafter, as an unsecured general
creditor, look only to the Company and the Guarantor for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company and the
Guarantor cause to be published once, in an Authorized Newspaper in each Place
of Payment for such series or to be mailed to Holders of Registered

                                       79
<PAGE>

Securities of such series, or both, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication or mailing nor shall it be later than two years
after such principal and any premium or interest or Additional Amounts shall
have become due and payable, any unclaimed balance of such money then remaining
will be repaid to the Company or the Guarantor, as the case may be.

     Section 10.4.  Additional Amounts.

     If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities.  Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

     Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, if the Securities of a series provide for
the payment of Additional Amounts, at least 10 days prior to the first Interest
Payment Date with respect to such series of Securities (or if the Securities of
such series shall not bear interest prior to Maturity, the first day on which a
payment of principal is made), and at least 10 days prior to each date of
payment of principal or interest if there has been any change with respect to
the matters set forth in the below-mentioned Officer's Certificate, the Company
shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if
other than the Trustee, an Officer's Certificate instructing the Trustee and
such Paying Agent or Paying Agents whether such payment of principal of and
premium, if any, or interest on the Securities of such series shall be made to
Holders of Securities of such series or the Coupons appertaining thereto who are
United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series.  If any such withholding shall be required, then such Officer's
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or Coupons, and the Company
agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Securities.  The Company covenants to indemnify
the Trustee and any Paying Agent for, and to hold them harmless against, any
loss, liability or expense reasonably incurred without negligence or bad faith
on their part arising out of or in connection with actions taken or omitted by
any of them in reliance on any Officer's Certificate furnished pursuant to this
Section 10.4.

     Section 10.5.  Corporate Existence.

     Subject to Article 8, the Company and the Guarantor shall do or cause to be
done all things necessary to preserve and keep in full force and effect their
respective corporate existences and that of each of their respective
Subsidiaries and their respective rights (charter and statutory) and franchises;
provided, however, that the foregoing shall not obligate the Company or the
Guarantor or any of their respective Subsidiaries to preserve any such right or
franchise if the Company, the Guarantor or any such Subsidiary shall determine
that the preservation thereof is no longer desirable in the conduct of its
business or the business of such Subsidiary and that the loss thereof is not
disadvantageous in any material respect to any Holder.

     Section 10.6.  Waiver of Certain Covenants.

     The Company or the Guarantor, as the case may be, may omit in any
particular instance to comply with any term, provision or condition set forth in
Section 10.5 with respect to the Securities of any series if before the time for
such compliance the Holders of at least a majority in principal amount of the
Outstanding Securities of such series, by Act of such Holders, either shall
waive such compliance in such instance or generally shall have waived compliance
with such term, provision or condition, but no such waiver shall extend to or
affect such term, provision or condition except to the extent so expressly
waived, and, until such waiver shall become effective, the obligations of the
Company and the Guarantor and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

          status thereof.

     compliance with the covenants contained in this Article 10 other than as

          and of performance under this Indenture has been made under his or her
          supervision, and

               (b)  to the best of his or her knowledge, based on such review,

the outstanding capital stock of the Company or the Guarantor, as the case may
be, or (b) make any payment of principal of, interest or premium, if any, on or
repay, repurchase or redeem any debt security of the Company or the Guarantor,
as the case may be, that ranks junior in interest to the Securities of such

be, has actual knowledge that (A) with the giving of notice or the lapse of time
or both, would constitute an Event of Default hereunder and (B) in respect of
which the Company or the Guarantor, as the case may be, shall not have taken
reasonable steps to cure, (2) the Company shall be in default with respect to
its payment of any obligations under the related Preferred Securities Guarantee

Securities of such series and shall not have rescinded such notice, or such
Extension Period, or any extension thereof, shall be continuing.

in accordance with such Trust Agreement.

     The Company covenants, as to each series of Securities issued to an ACE
Trust in connection with the issuance of Preferred Securities and Common
Securities by that ACE Trust, (a) to maintain directly or indirectly 100%
ownership of the Common Securities of such ACE Trust; provided, however, that
any permitted successor of the Company hereunder may succeed to the Company's

Securities in liquidation of such ACE Trust, (ii) the redemption of all of the
Preferred Securities and Common Securities of such ACE Trust or (iii) certain
mergers, consolidations or amalgamations, each as permitted by the Trust

     If less than all of the Securities of any series with the same issue date,
interest rate or formula, Stated Maturity and other terms are to be redeemed,
the particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal amount of Registered Securities of such
series; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Registered Security of such series not
redeemed to less than the minimum denomination for a Security of such series
established herein or pursuant hereto.

     The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal of such Securities which has been or is to be redeemed.

     Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted into other securities of the Company or exchanged for securities of
the Guarantor or another issuer in part before termination of the conversion or
exchange right with respect to the portion of the Security so selected, the
converted portion of such Security shall be deemed (so far as may be) to be the
portion selected for redemption.  Securities which have been converted or
exchanged during a selection of Securities to be redeemed shall be treated by
the Trustee as Outstanding for the purpose of such selection.

     Section 11.4.  Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 1.6,
not less than 30 nor more than 60 days prior to the Redemption Date, unless a
shorter period is specified in the Securities to be redeemed, to the Holders of
Securities to be redeemed.  Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

                                       85
<PAGE>

     Any notice that is mailed to the Holder of any Registered Securities in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not such Holder receives the notice.

     All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3)  if less than all Outstanding Securities of any series are to be
     redeemed, the identification (and, in the case of partial redemption, the
     principal amount) of the particular Security or Securities to be redeemed,

          (4)  in case any Security is to be redeemed in part only, the notice
     which relates to such Security shall state that on and after the Redemption
     Date, upon surrender of such Security, the Holder of such Security will
     receive, without charge, a new Security or Securities of authorized
     denominations for the principal amount thereof remaining unredeemed,

          (5)  that, on the Redemption Date, the Redemption Price shall become
     due and payable upon each such Security or portion thereof to be redeemed,
     and, if applicable, that interest thereon shall cease to accrue on and
     after said date,

          (6)  the place or places where such Securities, together (in the case
     of Bearer Securities) with all Coupons appertaining thereto, if any,
     maturing after the Redemption Date, are to be surrendered for payment of
     the Redemption Price and any accrued interest and Additional Amounts
     pertaining thereto,

          (7)  that the redemption is for a sinking fund, if such is the case,

          (8)  that, unless otherwise specified in such notice, Bearer
     Securities of any series, if any, surrendered for redemption must be
     accompanied by all Coupons maturing subsequent to the date fixed for
     redemption or the amount of any such missing Coupon or Coupons will be
     deducted from the Redemption Price, unless security or indemnity
     satisfactory to the Company, the Guarantor, the Trustee and any Paying
     Agent is furnished,

          (9)  if Bearer Securities of any series are to be redeemed and no
     Registered Securities of such series are to be redeemed, and if such Bearer
     Securities may be exchanged for Registered Securities not subject to
     redemption on the Redemption Date pursuant to Section 3.5 or otherwise, the
     last date, as determined by the Company, on which such exchanges may be
     made,

                                       86
<PAGE>

          (10) in the case of Securities of any series that are convertible into
     Common Stock of the Company or exchangeable for other securities, the
     conversion or exchange price or rate, the date or dates on which the right
     to convert or exchange the principal of the Securities of such series to be
     redeemed will commence or terminate and the place or places where such
     Securities may be surrendered for conversion or exchange, and

          (11) the CUSIP number or the Euroclear or the Cedel reference numbers
     of such Securities, if any (or any other numbers used by a Depository to
     identify such Securities).

     A notice of redemption published as contemplated by Section 1.6 need not
identify particular Registered Securities to be redeemed.

     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

     Section 11.5.  Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company or the Guarantor shall
deposit, with respect to the Securities of any series called for redemption
pursuant to Section 11.4, with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent or the Guarantor is acting as Paying
Agent, segregate and hold in trust as provided in Section 10.3) an amount of
money in the applicable Currency sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date, unless
otherwise specified pursuant to Section 3.1 or in the Securities of such series)
any accrued interest (including any Additional Interest) on and Additional
Amounts with respect thereto, all such Securities or portions thereof which are
to be redeemed on that date.

     Section 11.6.  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company and the Guarantor shall default in the payment of the Redemption Price
and accrued interest) such Securities shall cease to bear interest and the
Coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void.  Upon surrender of
any such Security for redemption in accordance with said notice, together with
all Coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with any accrued interest and Additional Amounts to the Redemption Date;
provided, however, that, except as otherwise provided in or pursuant to this
Indenture or the Bearer Securities of such series, installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only upon presentation and surrender of Coupons for such
interest (at an Office or Agency located outside the United States except as
otherwise provided in Section 10.2), and provided, further, that,

                                       87
<PAGE>

except as otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the Regular Record Dates therefor
according to their terms and the provisions of Section 3.7.

     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless.  If thereafter the Holder of such Security shall
surrender to the Trustee or any Paying Agent any such missing Coupon in respect
of which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that any
interest or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such
Security located outside of the United States except as otherwise provided in
Section 10.2.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium, until paid, shall bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

     Section 11.7.  Securities Redeemed in Part.

     Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing) and the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.  If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form so
surrendered.

     Section 11.8.  Right of Redemption of Securities Issued to an ACE Trust.

     In the case of the Securities of a series issued to an ACE Trust, except as
otherwise specified as contemplated by Section 3.1, if a Special Event in
respect of such ACE Trust shall occur and be continuing, the Company may, at its
option, redeem the Securities of such series

                                       88
<PAGE>

within 90 days of the occurrence of such Special Event, in whole but not in
part, subject to the provisions of this Section 11.8 and the other provisions of
this Article 11. Unless otherwise specified in or pursuant to this Indenture or
the Securities of such series, the redemption price for any Security so redeemed
pursuant to this Section 11.8 shall be equal to 100% of the principal amount of
such Securities then Outstanding plus accrued and unpaid interest, including any
Additional Interest, to the date fixed for redemption.

                                  ARTICLE 12

                                 Sinking Funds

     Section 12.1.  Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of such series is herein referred to as an "optional sinking
fund payment".  If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 12.2.  Each sinking fund payment shall be applied to the redemption
of Securities of any series as provided for by the terms of Securities of such
series and this Indenture.

     Section 12.2.  Satisfaction of Sinking Fund Payments with Securities.

     The Company or the Guarantor may, in satisfaction of all or any part of any
sinking fund payment with respect to the Securities of any series to be made
pursuant to the terms of such Securities (1) deliver Outstanding Securities of
such series (other than any of such Securities previously called for redemption
or any of such Securities in respect of which cash shall have been released to
the Company), together in the case of any Bearer Securities of such series with
all unmatured Coupons appertaining thereto, and (2) apply as a credit Securities
of such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously so
credited.  Such Securities shall be received and credited for such purpose by
the Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.  If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
12.2, the principal amount of Securities of such series to be redeemed in order
to satisfy the remaining sinking fund payment shall be less than $100,000, the
Trustee need not call Securities of such series for redemption, except upon
Company Request or Guarantor Request, and such cash payment shall be held by the
Trustee or a Paying Agent and applied to the next

                                       89
<PAGE>

succeeding sinking fund payment, provided, however, that the Trustee or such
Paying Agent shall at the request of the Company or the Guarantor from time to
time pay over and deliver to the Company or the Guarantor, as the case may be,
any cash payment so being held by the Trustee or such Paying Agent upon delivery
by the Company or the Guarantor to the Trustee of Securities of that series
purchased by the Company or the Guarantor having an unpaid principal amount
equal to the cash payment requested to be released to the Company or the
Guarantor.

     Section 12.3.  Redemption of Securities for Sinking Fund.

     Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered.  If such Officer's Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 60 days before each such sinking fund payment date the Trustee
shall select the Securities to be redeemed upon such sinking fund payment date
in the manner specified in Section 11.3 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 11.4.  Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 11.6 and 11.7.

                                  ARTICLE 13

                      Repayment at the Option of Holders

     Section 13.1.  Applicability of Article.

     Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 3.9, shall not
operate as a payment, redemption or satisfaction of the Indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a directive that such Securities be
cancelled. Notwithstanding anything to the contrary contained in this Section
13.1, in connection with any repayment of Securities, the Company may arrange
for the purchase of any Securities by an agreement with one or more investment
bankers or other purchasers to purchase such Securities by paying to the Holders
of such Securities on or before the close of business on the repayment date an
amount not less than the repayment price payable by the Company on repayment of
such Securities, and the obligation of the Company to pay the repayment price of
such Securities shall be satisfied and discharged to the extent such payment is
so paid by such purchasers.

                       Securities in Foreign Currencies

     Section 14.1.  Applicability of Article.

     Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company or the Guarantor may
specify in a written notice to the Trustee.

     Section 15.1.  Purposes for Which Meetings May Be Called.

     A meeting of Holders of Securities of any series may be called at any time
and from time to time pursuant to this Article to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

     Section 15.2.  Call, Notice and Place of Meetings.

          (1)  The Trustee may at any time call a meeting of Holders of
     Securities of any series for any purpose specified in Section 15.1, to be
     held at such time and at such place in the Borough of Manhattan, The City
     of New York, or, if Securities of such series have been issued in whole or
     in part as Bearer Securities, in London or in such place outside the United
     States as the Trustee shall determine.  Notice of every meeting of Holders
     of Securities of any series, setting forth the time and the place of such
     meeting and in general terms the action proposed to be taken at such
     meeting, shall be given, in the manner provided in Section 1.6, not less
     than 21 nor more than 180 days prior to the date fixed for the meeting.

          (2)  In case at any time the Company (by or pursuant to a Board
     Resolution), the Guarantor (by or pursuant to a Guarantor's Board
     Resolution) or the Holders of at least 10% in principal amount of the
     Outstanding Securities of any series shall have requested the Trustee to
     call a meeting of the Holders of Securities of such series for any

                                       91
<PAGE>

     purpose specified in Section 15.1, by written request setting forth in
     reasonable detail the action proposed to be taken at the meeting, and the
     Trustee shall not have mailed notice of or made the first publication of
     the notice of such meeting within 21 days after receipt of such request
     (whichever shall be required pursuant to Section 1.6) or shall not
     thereafter proceed to cause the meeting to be held as provided herein, then
     the Company, the Guarantor or the Holders of Securities of such series in
     the amount above specified, as the case may be, may determine the time and
     the place in the Borough of Manhattan, The City of New York, or, if
     Securities of such series are to be issued as Bearer Securities, in London
     for such meeting and may call such meeting for such purposes by giving
     notice thereof as provided in clause (1) of this Section.

     Section 15.3.  Persons Entitled to Vote at Meetings.

     To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such

speak at any meeting of Holders of Securities of any series shall be the Persons
entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel, any representatives of the Guarantor and its counsel
and any representatives of the Company and its counsel.

     Section 15.4.  Quorum; Action.

     The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for any meeting of
Holders of Securities of such series.  In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting.  In the absence of a quorum at any reconvened meeting, such
reconvened meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such reconvened meeting.  Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 15.2(1), except that such notice need be
given only once not less than five days prior to the date on which the meeting
is scheduled to be reconvened.  Notice of the reconvening of an adjourned
meeting shall state expressly the percentage, as provided above, of the
principal amount of the Outstanding Securities of such series which shall
constitute a quorum.

     Except as limited by the proviso to Section 9.2, any resolution presented
to a meeting or adjourned meeting duly reconvened at which a quorum is present
as aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2, any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the

                                       92
<PAGE>

Holders of a specified percentage, which is less than a majority, in principal
amount of the Outstanding Securities of a series may be adopted at a meeting or
an adjourned meeting duly reconvened and at which a quorum is present as

principal amount of the Outstanding Securities of such series.

     Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

     Section 15.5.  Determination of Voting Rights; Conduct and Adjournment of
Meetings.

          (1)  Notwithstanding any other provisions of this Indenture, the
     Trustee may make such reasonable regulations as it may deem advisable for
     any meeting of Holders of Securities of such series in regard to proof of
     the holding of Securities of such series and of the appointment of proxies
     and in regard to the appointment and duties of inspectors of votes, the
     submission and examination of proxies, certificates and other evidence of
     the right to vote, and such other matters concerning the conduct of the
     meeting as it shall deem appropriate.  Except as otherwise permitted or
     required by any such regulations, the holding of Securities shall be proved
     in the manner specified in Section 1.4 and the appointment of any proxy
     shall be proved in the manner specified in Section 1.4 or by having the
     signature of the person executing the proxy witnessed or guaranteed by any
     trust company, bank or banker authorized by Section 1.4 to certify to the
     holding of Bearer Securities.  Such regulations may provide that written
     instruments appointing proxies, regular on their face, may be presumed
     valid and genuine without the proof specified in Section 1.4 or other
     proof.

          (2)  The Trustee shall, by an instrument in writing, appoint a
     temporary chairman of the meeting, unless the meeting shall have been
     called by the Company or by Holders of Securities as provided in Section
     15.2(2), in which case the Company, the Guarantor or the Holders of
     Securities of the series calling the meeting, as the case may be, shall in
     like manner appoint a temporary chairman.  A permanent chairman and a
     permanent secretary of the meeting shall be elected by vote of the Persons
     entitled to vote a majority in principal amount of the Outstanding
     Securities of such series represented at the meeting.

          (3)  At any meeting, each Holder of a Security of such series or proxy
     shall be entitled to one vote for each $1,000 principal amount of
     Securities of such series held or represented by him; provided, however,
     that no vote shall be cast or counted at any meeting in respect of any
     Security challenged as not Outstanding and ruled by the chairman of the
     meeting to be not Outstanding. The chairman of the meeting shall have no
     right to vote, except as a Holder of a Security of such series or proxy.

          (4)  Any meeting of Holders of Securities of any series duly called
     pursuant to Section 15.2 at which a quorum is present may be adjourned from
     time to time by

                                       93
<PAGE>

     Persons entitled to vote a majority in principal amount of the Outstanding
     Securities of such series represented at the meeting; and the meeting may
     be held as so adjourned without further notice.

     Section 15.6.  Counting Votes and Recording Action of Meetings.

     The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting.  A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 15.2 and, if
applicable, Section 15.4.  Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and the Guarantor, and another to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting.  Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

                          Subordination Of Securities

     Section 16.1.  Agreement to Subordinate.

     The Company covenants and agrees, and each Holder of Securities issued
hereunder and under any indenture supplemental hereto or pursuant to a Board
Resolution, Officer's Certificate and Guarantor's Officer's Certificate

or Event of Default hereunder.

     Section 16.2.  Default on Company Senior Indebtedness.

     In the event and during the continuation of any default by the Company in
the payment of principal, premium, interest or any other amount due on any
Company Senior Indebtedness with respect to the Securities of any series, or in
the event that the maturity of any Company Senior Indebtedness with respect to
the Securities of any series has been accelerated because of a default, then, in
either case, no payment shall be made by the Company with respect to the
principal (including redemption and sinking fund payments) of, any premium or
interest (including any Additional Interest) on, or any Additional Amounts with
respect to, the Securities of such series.

     In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 16.2, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of such Company
Senior Indebtedness or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Company Senior
Indebtedness may have been issued, as their respective interests may appear, but
only to the extent that the holders of such Company Senior Indebtedness (or
their representative or representatives or a trustee) notify the Trustee in
writing within 90 days of such payment of the amounts then due and owing on such
Company Senior Indebtedness and only the amounts specified in such notice to the

any kind or character, whether in cash, property or securities, to creditors
upon any dissolution, winding-up, liquidation or reorganization of the Company,
whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or
other proceedings, all amounts due upon all Company Senior Indebtedness with
respect to the Securities of any series shall first be paid in full, or payment
thereof provided for in money in accordance with its terms, before any payment
is made by the Company on account of the principal of, premium or interest
(including any Additional Interest) on, or Additional Amounts with respect to,
the Securities of such series; and upon any such dissolution, winding-up,
liquidation or reorganization, any payment by the Company, or distribution of
assets of the Company of any kind or character, whether in cash, property or
securities, to which the Holders or the Trustee would be entitled to receive
from the Company, except for the provisions of this Article 16, shall be paid by
the Company or by any receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, or by the Holders or
by the Trustee under this Indenture if received by them or it, directly to the
holders of such Company Senior Indebtedness (pro rata to such holders on the
basis of the respective amounts of such Company Senior Indebtedness held by such
holders, as calculated by the Company) or their representative or
representatives, or to the trustee or trustees

                                       95

under any indenture pursuant to which any instruments evidencing such Company
Senior Indebtedness may have been issued, as their respective interests may
appear, to the extent necessary to pay such Company Senior Indebtedness in full,
in money or money's worth, after giving effect to any concurrent payment or
distribution to or for the holders of such Company Senior Indebtedness, before
any payment or distribution is made to the Holders of the Securities of such
series or to the Trustee.

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing shall be received by the
Trustee before all such Company Senior Indebtedness is paid in full, or
provision is made for such payment in money in accordance with its terms, such
payment or distribution shall be held in trust for the benefit of and shall be
paid over or delivered to the holders of such Company Senior Indebtedness or
their representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Company Senior
Indebtedness may have been issued, as their respective interests may appear, as
calculated by the Company, for application to the payment of all such Company
Senior Indebtedness remaining unpaid to the extent necessary to pay such Company
Senior Indebtedness in full in money in accordance with its terms, after giving
effect to any concurrent payment or distribution to or for the benefit of the
holders of such Company Senior Indebtedness.

     For purposes of this Article 16, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article 16 with respect to
the Securities of the relevant series to the payment of all Company Senior
Indebtedness with respect to the Securities of such series that may at the time
be outstanding, provided that (i) such Company Senior Indebtedness is assumed by
the new corporation, if any, resulting from any such reorganization or
readjustment, and (ii) the rights of the holders of such Company Senior
Indebtedness are not, without the consent of such holders, altered by such
reorganization or readjustment.  The consolidation of the Company with, or the

the Company following the conveyance, transfer or lease of its property as an
entirety, or substantially as an entirety, to another Person upon the terms and
conditions provided for in Sections 8.1 and 8.2 of this Indenture shall not be
deemed a dissolution, winding-up, liquidation or reorganization for the purposes
of this Section 16.3 if such other Person shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Sections 8.1 and 8.2 of this Indenture.  Nothing in Section 16.2 or in this
Section 16.3 shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 6.6 of this Indenture.

     Section 16.4.  Subrogation.

     Subject to the payment in full of all Company Senior Indebtedness with
respect to the Securities of any series, the rights of the Holders of the
Securities of such series shall be

                                       96
<PAGE>

subrogated to the rights of the holders of such Company Senior Indebtedness to
receive payments or distributions of cash, property or securities of the Company
applicable to such Company Senior Indebtedness until the principal of, any
premium and interest (including any Additional Interest) on, and any Additional
Amounts with respect to, the Securities of such series shall be paid in full;
and, for the purposes of such subrogation, no payments or distributions to the
holders of such Company Senior Indebtedness of any cash, property or securities
to which the Holders or the Trustee would be entitled except for the provisions
of this Article 16, and no payment over pursuant to the provisions of this
Article 16 to or for the benefit of the holders of such Company Senior
Indebtedness by Holders of the Securities of such series or the Trustee, shall,
as between the Company, its creditors other than holders of such Company Senior
Indebtedness, and the Holders of the Securities of such series, be deemed to be
a payment by the Company to or on account of such Company Senior Indebtedness.
It is understood that the provisions of this Article 16 are and are intended
solely for the purposes of defining the relative rights of the Holders of the
Securities of each series, on the one hand, and the holders of the Company
Senior Indebtedness with respect to the Securities of such series on the other
hand.

     Nothing contained in this Article 16 or elsewhere in this Indenture, any
Additional Provisions or in the Securities of any series is intended to or shall
impair, as between the Company, its creditors other than the holders of Company
Senior Indebtedness with respect to the Securities of such series, and the
Holders of the Securities of such series, the obligation of the Company, which
is absolute and unconditional, to pay to the Holders of the Securities of such
series the principal of, any premium and interest (including any Additional
Interest) on, and any Additional Amounts with respect to, the Securities of such
series as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders of the Securities of such series and creditors of the Company, other
than the holders of such Company Senior Indebtedness, nor shall anything herein
or therein prevent the Trustee or the Holder of any Security of such series from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article 16 of the
holders of such Company Senior Indebtedness in respect of cash, property or
securities of the Company, as the case may be, received upon the exercise of any
such remedy.

     Upon any payment or distribution of assets of the Company referred to in
this Article 16, the Trustee, subject to the provisions of Article 6 of this
Indenture, and the Holders shall be entitled to conclusively rely upon any order
or decree made by any court of competent jurisdiction in which such dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent
or other Person making such payment or distribution, delivered to the Trustee or
to the Holders of the Securities of any series, for the purposes of ascertaining
the Persons entitled to participate in such distribution, the holders of Company
Senior Indebtedness with respect to the Securities of such series and other
indebtedness of the Company, as the case may be, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article 16.

     Section 16.5.  Trustee to Effectuate Subordination.

     Each Holder of Securities by such Holder's acceptance thereof authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article 16 and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes.

     Section 16.6.  Notice by the Company.

     The Company shall give prompt written notice to a Responsible Officer of
the Trustee of any fact known to the Company that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities of any
series pursuant to the provisions of this Article 16.  Notwithstanding the
provisions of this Article 16 or any other provision of this Indenture or any
Additional Provisions, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Securities of any series pursuant to the
provisions of this Article 16, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Company or a holder
or holders of Company Senior Indebtedness with respect to the Securities of such
series or from any trustee therefor; and before the receipt of any such written
notice, the Trustee, subject to the provisions of Article 6 of this Indenture,
shall be entitled in all respects to assume that no such facts exist; provided,
however, that if the Trustee shall not have received the notice provided for in
this Section 16.6 at least two Business Days prior to the date upon which by the
terms hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of, any premium or interest (including
any Additional Interest) on, or any Additional Amounts with respect to, any
Security of such series), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
money and to apply the same to the purposes for which they were received, and
shall not be affected by any notice to the contrary that may be received by it
within two Business Days prior to such date.

     The Trustee, subject to the provisions of Article 6 of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Company Senior Indebtedness
with respect to the Securities of any series (or a trustee on behalf of such
holder), to establish that such notice has been given by a holder of such
Company Senior Indebtedness or a trustee on behalf of any such holder or
holders.  In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of such
Company Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 16, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of such
Company Senior Indebtedness held by such Person, the extent to which such Person
is entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 16, and, if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

     Upon any payment or distribution of assets of the Company referred to in
this Article 16, the Trustee and the Holders shall be entitled to rely upon any
order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding-up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of the Securities of
any series, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of Company Senior Indebtedness with
respect to the Securities of such series and other indebtedness of the Company,
the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article 16.

     Section 16.7.  Rights of the Trustee; Holders of Company Senior
Indebtedness.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article 16 in respect of any Company Senior Indebtedness with
respect to the Securities of any series at any time held by it, to the same
extent as any other holder of such Company Senior Indebtedness, and nothing in
this Indenture or any Additional Provisions shall deprive the Trustee of any of
its rights as such holder.

     With respect to the holders of Company Senior Indebtedness with respect to
the Securities of any series, the Trustee undertakes to perform or to observe
only such of its covenants and obligations as are specifically set forth in this
Article 16, and no implied covenants or obligations with respect to the holders
of such Company Senior Indebtedness shall be read into this Indenture or any
Additional Provisions against the Trustee.  The Trustee shall not be deemed to
owe any fiduciary duty to the holders of such Company Senior Indebtedness and,
subject to the provisions of Article 6 of this Indenture, the Trustee shall not
be liable to any holder of such Company Senior Indebtedness if it shall pay over
or deliver to Holders of the Securities of such series, the Company or any other
Person money or assets to which any holder of such Company Senior Indebtedness
shall be entitled by virtue of this Article 16 or otherwise.

     Nothing in this Article 16 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.6.

     Section 16.8.  Subordination May Not Be Impaired

     No right of any present or future holder of any Company Senior Indebtedness
to enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company,
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof that any such holder may have or
otherwise be charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Company Senior Indebtedness with respect to the Securities of any
series may, at any time and

                                       99
<PAGE>

from time to time, without the consent of or notice to the Trustee or the
Holders of Securities of such series, without incurring responsibility to such
Holders and without impairing or releasing the subordination provided in this
Article 16 or the obligations hereunder of the Holders of the Securities of such
series to the holders of such Company Senior Indebtedness, do any one or more of
the following: (i) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, such Company Senior Indebtedness, or
otherwise amend or supplement in any manner such Company Senior Indebtedness or
any instrument evidencing the same or any agreement under which such Company
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing such Company
Senior Indebtedness; (iii) release any Person liable in any manner for the
collection of such Company Senior Indebtedness; and (iv) exercise or refrain
from exercising any rights against the Company and any other Person.

                            Guarantee And Indemnity

     Section 17.1.  The Guarantee.

     The Guarantor hereby unconditionally guarantees to each Holder of a
Security authenticated and delivered by the Trustee the due and punctual payment
of the principal of, any premium and interest (including any Additional
Interest) on, any Additional Amounts, and, if applicable, any Additional Sums
with respect to such Security and the due and punctual payment of the sinking
fund payments (if any) provided for pursuant to the terms of such Security, when
and as the same shall become due and payable, whether at maturity, by
acceleration, redemption, repayment or otherwise, in accordance with the terms
of such Security and of this Indenture.  In case of the failure of the Company
punctually to pay any such principal, premium, interest (including any
Additional Interest), Additional Amounts, Additional Sums or sinking fund
payment, the Guarantor hereby agrees to cause any such payment to be made
punctually when and as the same shall become due and payable, whether at
maturity, upon acceleration, redemption, repayment or otherwise, and as if such
payment were made by the Company.

     Section 17.2.  Net Payments.

     All payments of principal of and premium, if any, interest (including any
Additional Interest) and any other amounts on, or in respect of, the Securities
of any series or any Coupon appertaining thereto shall be made by the Guarantor
without withholding or deduction at source for, or on account of, any present or
future taxes, fees, duties, assessments or governmental charges of whatever
nature imposed or levied by or on behalf of the Cayman Islands or Bermuda (each,
a "taxing jurisdiction") or any political subdivision or taxing authority
thereof or therein, unless such taxes, fees, duties, assessments or governmental
charges are required to be withheld or deducted by (i) the laws (or any
regulations or ruling promulgated thereunder) of a taxing jurisdiction or any
political subdivision or taxing authority thereof or therein or (ii) an official
position regarding the application, administration, interpretation or
enforcement of any such laws, regulations or rulings (including, without
limitation, a holding by a court of competent

                                      100
<PAGE>

jurisdiction or by a taxing authority in a taxing jurisdiction or any political
subdivision thereof). If a withholding or deduction at source is required, the
Guarantor shall, subject to certain limitations and exceptions set forth below,
pay to the Holder of any such Security or any Coupon appertaining thereto such
Additional Amounts as may be necessary so that every net payment of principal,
premium, if any, interest or any other amount made to such Holder, after such
withholding or deduction, shall not be less than the amount provided for in such
Security, any Coupons appertaining thereto and this Indenture to be then due and
payable; provided, however, that the Guarantor shall not be required to make
         --------  -------
payment of such Additional Amounts for or on account of:

          (1)  any tax, fee, duty, assessment or governmental charge of whatever
     nature which would not have been imposed but for the fact that such Holder:
     (A) was a resident, domiciliary or national of, or engaged in business or
     maintained a permanent establishment or was physically present in, the
     relevant taxing jurisdiction or any political subdivision thereof or
     otherwise had some connection with the relevant taxing jurisdiction other
     than by reason of the mere ownership of, or receipt of payment under, such
     Security; (B) presented such Security for payment in the relevant taxing
     jurisdiction or any political subdivision thereof, unless such Security
     could not have been presented for payment elsewhere; or (C) presented such
     Security more than thirty (30) days after the date on which the payment in
     respect of such Security first became due and payable or provided for,
     whichever is later, except to the extent that the Holder would have been
     entitled to such Additional Amounts if it had presented such Security for
     payment on any day within such period of  thirty (30) days;

          (2)  any estate, inheritance, gift, sale, transfer, personal property
     or similar tax, assessment or other governmental charge;

          (3)  any tax, assessment or other governmental charge that is imposed
     or withheld by reason of the failure by the Holder or the beneficial owner
     of such Security to comply with any reasonable request by the Guarantor
     addressed to the Holder within 90 days of such request (A) to provide
     information concerning the nationality, residence or identity of the Holder
     or such beneficial owner or (B) to make any declaration or other similar
     claim or satisfy any information or reporting requirement, which, in the
     case of (A) or (B), is required or imposed by statute, treaty, regulation
     or administrative practice of the relevant taxing jurisdiction or any
     political subdivision thereof as a precondition to exemption from all or
     part of such tax, assessment or other governmental charge; or

          (4)  any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such Security to the extent such payment would be required
by the laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for
tax purposes of a beneficiary or partner or settlor with respect to such
fiduciary or a member of such

                                      101
<PAGE>

partnership or a beneficial owner who would not have been entitled to such
Additional Amounts had it been the Holder of the Security.

     Whenever in this Indenture there is mentioned, in any context, the payment
of the principal of or any premium, interest or any other amounts on, or in
respect of, any Security of any series or any Coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
by the terms of such series established hereby or pursuant hereto to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof pursuant to such terms, and express mention of the payment of
Additional Amounts (if applicable) in any provision hereof shall not be
construed as excluding the payment of Additional Amounts in those provisions
hereof where such express mention is not made.

     Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, at least 10 days prior to the first
Interest Payment Date with respect to a series of Securities (or if the
Securities of such series shall not bear interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or interest if there has been any change with
respect to the matters set forth in the below-mentioned Guarantor's Officer's
Certificate, the Guarantor shall furnish to the Trustee and the principal Paying
Agent or Paying Agents, if other than the Trustee, a Guarantor's Officer's
Certificate instructing the Trustee and such Paying Agent or Paying Agents
whether such payment of principal of and premium, if any, interest or any other
amounts on the Securities of such series shall be made to Holders of Securities
of such series or the Coupons appertaining thereto without withholding for or on
account of any tax, fee, duty, assessment or other governmental charge described
in this Section 17.2.  If any such withholding shall be required, then such
Guarantor's Officer's Certificate shall specify by taxing jurisdiction the
amount, if any, required to be withheld on such payments to such Holders of
Securities or Coupons, and the Guarantor agrees to pay to the Trustee or such
Paying Agent the Additional Amounts required by this Section 17.2.  The
Guarantor covenants to indemnify the Trustee and any Paying Agent for, and to
hold them harmless against, any loss, liability or expense reasonably incurred
without negligence or bad faith on their part arising out of or in connection
with actions taken or omitted by any of them in reliance on any Guarantor's
Officer's Certificate furnished pursuant to this Section 17.2.

     Section 17.3.  Guarantee Unconditional, etc.

     The Guarantor hereby agrees that its obligations hereunder shall be as
principal and not merely as surety, and shall be absolute, irrevocable and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of any Security or this Indenture, any failure
to enforce the provisions of any Security or this Indenture, or any waiver,
modification, consent or indulgence granted with respect thereto by the Holder
of such Security or the Trustee, the recovery of any judgment against the
Company or any action to enforce the same, or any other circumstances which may
otherwise constitute a legal or equitable discharge of a surety or guarantor.
The Guarantor hereby waives diligence, presentment, demand of

                                      102
<PAGE>

payment, filing of claims with a court in the event of merger, insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest or notice with respect to any such Security or the Indebtedness
evidenced thereby and all demands whatsoever, and covenants that this Guarantee
will not be discharged except by payment in full of the principal of, any
premium and interest (including any Additional Interest) on, and any Additional
Amounts, and, if applicable, any Additional Sums and sinking fund payments
required with respect to, the Securities and the complete performance of all
other obligations contained in the Securities. The Guarantor further agrees, to
the fullest extent that it lawfully may do so, that, as between the Guarantor,
on the one hand, and the Holders and the Trustee, on the other hand, the
Maturity of the obligations guaranteed hereby may be accelerated as provided in
Section 5.2 hereof for the purposes of this Guarantee, notwithstanding any stay,
injunction or prohibition extant under any bankruptcy, insolvency,
reorganization or other similar law of any jurisdiction preventing such
acceleration in respect of the obligations guaranteed hereby.

     Section 17.4.  Reinstatement.

     This Guarantee shall continue to be effective or be reinstated, as the case
may be, if at any time payment on any Security, in whole or in part, is
rescinded or must otherwise be restored to the Company or the Guarantor upon the
bankruptcy, liquidation or reorganization of the Company or otherwise.

     Section 17.5.  Subrogation.

     The Guarantor shall be subrogated to all rights of the Holder of any
Security against the Company in respect of any amounts paid to such Holder by
the Guarantor pursuant to the provisions of this Guarantee; provided, however,
that the Guarantor shall not be entitled to enforce, or to receive any payments
arising out of or based upon, such right of subrogation until the principal of,
any premium and interest (including any Additional Interest) on, and any
Additional Amounts and, if applicable, any Additional Sums and sinking fund
payments required with respect to, all Securities shall have been paid in full.

     Section 17.6.  Indemnity.

     As a separate and alternative stipulation, the Guarantor unconditionally
and irrevocably agrees that any sum expressed to be payable by the Company under
this Indenture, the Securities or the Coupons but which is for any reason
(whether or not now known or becoming known to the Company, the Guarantor, the
Trustee or any Holder of any Security or Coupon) not recoverable from the
Guarantor on the basis of a guarantee will nevertheless be recoverable from it
as if it were the sole principal debtor and will be paid by it to the Trustee on
demand.  This indemnity constitutes a separate and independent obligation from
the other obligations in this Indenture, gives rise to a separate and
independent cause of action and will apply irrespective of any indulgence
granted by the Trustee or any Holder of any Security or Coupon.

hereunder and under any Additional Provisions, by such Holder's acceptance
thereof likewise covenants and agrees, that all Securities shall be issued

any premium and interest (including any Additional Interest) on, any Additional
Amounts and, if applicable, any Additional Sums with respect to all Securities
of each series issued hereunder and under any Additional Provisions shall, to
the extent and in the manner hereinafter set forth, be subordinate in right of
payment to the prior payment in full of all Guarantor Senior Indebtedness with
respect to such series, whether outstanding at the date of this Indenture or
thereafter incurred.

     No provision of this Article 18 shall prevent the occurrence of any default
or Event of Default hereunder.

     In the event and during the continuation of any default by the Guarantor in
the payment of principal, premium, interest (including any Additional Interest)
or any other amount due on any Guarantor Senior Indebtedness with respect to the
Securities of any series, or in the event that the maturity of any Guarantor
Senior Indebtedness with respect to the Securities of any series has been
accelerated because of a default, then, in either case, no payment shall be made
by the Guarantor pursuant to the Guarantee with respect to the principal
(including redemption and sinking fund payments) of, any premium or interest
(including any Additional Interest) on, or any Additional Amounts or, if
applicable, Additional Sums with respect to, the Securities of such series.

benefit of, and shall be paid over or delivered to, the holders of such
Guarantor Senior Indebtedness or their respective representatives, or to the
trustee or trustees under any indenture pursuant to which any of such Guarantor
Senior Indebtedness may have been issued, as their respective interests may
appear, but only to the extent that the holders of such Guarantor Senior
Indebtedness (or their representative or representatives or a trustee) notify
the Trustee in writing within 90 days of such payment of the amounts then due
and owing on such Guarantor Senior Indebtedness and only the amounts

specified in such notice to the Trustee shall be paid to the holders of such

     Section 18.3.  Liquidation; Dissolution; Bankruptcy.

     Upon any payment by the Guarantor or distribution of assets of the
Guarantor of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution, winding-up, liquidation or reorganization of the
Guarantor, whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due upon all Guarantor Senior
Indebtedness with respect to the Securities of any series shall first be paid in
full, or payment thereof provided for in money in accordance with its terms,
before any payment is made by the Guarantor pursuant to the Guarantee on account
of the principal of, premium or interest (including any Additional Interest) on,
or Additional Amounts or, if applicable, Additional Sums with respect to, the
Securities of such series; and upon any such dissolution, winding-up,
liquidation or reorganization, any payment by the Guarantor, or distribution of
assets of the Guarantor of any kind or character, whether in cash, property or
securities, to which the Holders or the Trustee would be entitled to receive
from the Guarantor, except for the provisions of this Article 18, shall be paid
by the Guarantor or by any receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, or by the Holders or
by the Trustee under this Indenture if received by them or it, directly to the
holders of such Guarantor Senior Indebtedness (pro rata to such holders on the
basis of the respective amounts of such Guarantor Senior Indebtedness held by
such holders, as calculated by the Guarantor) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Guarantor Senior Indebtedness may have
been issued, as their respective interests may appear, to the extent necessary
to pay such Guarantor Senior Indebtedness in full, in money or money's worth,
after giving effect to any concurrent payment or distribution to or for the
holders of such Guarantor Senior Indebtedness, before any payment or
distribution is made pursuant to the Guarantee to the Holders of the Securities
of such series or to the Trustee.

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Guarantor pursuant to the Guarantee of any kind or
character, whether in cash, property or securities, prohibited by the foregoing
shall be received by the Trustee before all such Guarantor Senior Indebtedness
is paid in full, or provision is made for such payment in money in accordance
with its terms, such payment or distribution shall be held in trust for the
benefit of and shall be paid over or delivered to the holders of such Guarantor
Senior Indebtedness or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing such Guarantor Senior Indebtedness may have been issued, as their
respective interests may appear, as calculated by the Guarantor, for application
to the payment of all such Guarantor Senior Indebtedness remaining unpaid to the
extent necessary to pay such Guarantor Senior Indebtedness in full in money in
accordance with its terms, after giving effect to any concurrent payment or
distribution to or for the benefit of the holders of such Guarantor Senior
Indebtedness.

     For purposes of this Article 18, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Guarantor as reorganized
or readjusted, or securities of the Guarantor or any other corporation provided
for by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article 18 with respect to
the Guarantee in respect of any series of Securities to the payment of all
Guarantor Senior Indebtedness with respect to the Securities of such series that
may at the time be outstanding, provided that (i) such Guarantor Senior
Indebtedness is assumed by the new corporation, if any, resulting from any such
reorganization or readjustment, and (ii) the rights of the holders of such
Guarantor Senior Indebtedness are not, without the consent of such holders,
altered by such reorganization or readjustment.  The consolidation of the
Guarantor with, or the merger of the Guarantor into, another Person or the
liquidation or dissolution of the Guarantor following the conveyance, transfer
or lease of its property as an entirety, or substantially as an entirety, to
another Person upon the terms and conditions provided for in Sections 8.3 and
8.4 of this Indenture shall not be deemed a dissolution, winding-up, liquidation
or reorganization for the purposes of this Section 18.3 if such other Person
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions stated in Sections 8.3 and 8.4 of this Indenture.  Nothing
in Section 18.2 or in this Section 18.3 shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 6.6 of this Indenture.

     Section 18.4.  Subrogation.

     Subject to the payment in full of all Guarantor Senior Indebtedness with
respect to the Securities of any series, the rights of the Holders of the
Securities of such series shall be subrogated to the rights of the holders of
such Guarantor Senior Indebtedness to receive payments or distributions of cash,
property or securities of the Guarantor applicable to such Guarantor Senior
Indebtedness until the principal of, any premium and interest (including any
Additional Interest) on, and any Additional Amounts or, if applicable,
Additional Sums with respect to, the Securities of such series shall be paid in
full; and, for the purposes of such subrogation, no payments or distributions to
the holders of such Guarantor Senior Indebtedness of any cash, property or
securities to which the Holders or the Trustee would be entitled except for the
provisions of this Article 18, and no payment over pursuant to the provisions of
this Article 18 to or for the benefit of the holders of such Guarantor Senior
Indebtedness by Holders of the Securities of such series or the Trustee, shall,
as between the Guarantor, its creditors other than holders of such Guarantor
Senior Indebtedness, and the Holders of the Securities of such series, be deemed
to be a payment by the Guarantor to or on account of such Guarantor Senior
Indebtedness.  It is understood that the provisions of this Article 18 are and
are intended solely for the purposes of defining the relative rights of the
Holders of the Securities of each series, on the one hand, and the holders of
such Guarantor Senior Indebtedness with respect to the Securities of such series
on the other hand.

     Nothing contained in this Article 18 or elsewhere in this Indenture, any
Additional Provisions or in the Securities of any series is intended to or shall
impair, as between the Guarantor, its creditors other than the holders of
Guarantor Senior Indebtedness with respect to the Securities of such series, and
the Holders of the Securities of such series, the obligation of the

                                      106
<PAGE>

Guarantor, which is absolute and unconditional, to pay to the Holders of the
Securities of such series pursuant to the Guarantee the principal of, any
premium and interest (including any Additional Interest) on, and any Additional
Amounts or, if applicable, Additional Sums with respect to, the Securities of
such series as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders of the Securities of such series and creditors of the Guarantor, other
than the holders of such Guarantor Senior Indebtedness, nor shall anything
herein or therein prevent the Trustee or the Holder of any Security of such
series from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article
18 of the holders of such Guarantor Senior Indebtedness in respect of cash,
property or securities of the Guarantor, as the case may be, received upon the
exercise of any such remedy.

     Upon any payment or distribution of assets of the Guarantor referred to in
this Article 18, the Trustee, subject to the provisions of Article 6 of this
Indenture, and the Holders shall be entitled to conclusively rely upon any order
or decree made by any court of competent jurisdiction in which such dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent
or other Person making such payment or distribution, delivered to the Trustee or
to the Holders of the Securities of any series, for the purposes of ascertaining
the Persons entitled to participate in such distribution, the holders of
Guarantor Senior Indebtedness with respect to the Securities of such series and
other indebtedness of the Guarantor, as the case may be, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article 18.

     Section 18.5.  Trustee to Effectuate Subordination.

     Each Holder of Securities by such Holder's acceptance thereof authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article 18 and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes.

     Section 18.6.  Notice by the Guarantor.

     The Guarantor shall give prompt written notice to a Responsible Officer of
the Trustee of any fact known to the Guarantor that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities of any
series pursuant to the provisions of this Article 18.  Notwithstanding the
provisions of this Article 18 or any other provision of this Indenture or any
Additional Provisions, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Securities of any series pursuant to the
provisions of this Article 18, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Guarantor or a
holder or holders of Guarantor Senior Indebtedness with respect to the
Securities of such series or from any trustee therefor; and before the receipt
of any such written notice, the Trustee, subject to the provisions of Article 6
of this Indenture, shall be entitled in all respects to assume that no such
facts exist; provided, however, that if the Trustee shall not have received the

                                      107
<PAGE>

notice provided for in this Section 18.6 at least two Business Days prior to the
date upon which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment pursuant to the Guarantee of the
principal of, any premium or interest (including any Additional Interest) on, or
any Additional Amounts or, if applicable, Additional Sums with respect to, any
Security of such series), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
money and to apply the same to the purposes for which they were received, and
shall not be affected by any notice to the contrary that may be received by it
within two Business Days prior to such date.

     The Trustee, subject to the provisions of Article 6 of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Guarantor Senior Indebtedness
with respect to the Securities of any series (or a trustee on behalf of such
holder), to establish that such notice has been given by a holder of such
Guarantor Senior Indebtedness or a trustee on behalf of any such holder or
holders.  In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of such
Guarantor Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 18, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of such
Guarantor Senior Indebtedness held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such Person under this Article 18, and, if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

     Upon any payment or distribution of assets of the Guarantor referred to in
this Article 18, the Trustee and the Holders shall be entitled to rely upon any
order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding-up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of the Securities of
any series, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of Guarantor Senior Indebtedness
with respect to the Securities of such series and other indebtedness of the
Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 18.

     Section 18.7.  Rights of the Trustee; Holders of Guarantor Senior
Indebtedness.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article 18 in respect of any Guarantor Senior Indebtedness
with respect to the Securities of any series at any time held by it, to the same
extent as any other holder of such Guarantor Senior Indebtedness, and nothing in
this Indenture or any Additional Provisions shall deprive the Trustee of any of
its rights as such holder.

     With respect to the holders of Guarantor Senior Indebtedness with respect
to the Securities of any series, the Trustee undertakes to perform or to observe
only such of its

                                      108
<PAGE>

covenants and obligations as are specifically set forth in this Article 18, and
no implied covenants or obligations with respect to the holders of such
Guarantor Senior Indebtedness shall be read into this Indenture or any
Additional Provisions against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of such Guarantor Senior Indebtedness and,
subject to the provisions of Article 6 of this Indenture, the Trustee shall not
be liable to any holder of such Guarantor Senior Indebtedness if it shall pay
over or deliver to Holders of the Securities of such series, the Guarantor or
any other Person money or assets to which any holder of such Guarantor Senior
Indebtedness shall be entitled by virtue of this Article 18 or otherwise.

     Nothing in this Article 18 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.6.

     Section 18.8.  Subordination May Not Be Impaired.

     No right of any present or future holder of any Guarantor Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Guarantor, or by any act or failure to act, in good faith, by any such
holder, or by any noncompliance by the Guarantor with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof that any such
holder may have or otherwise be charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Guarantor Senior Indebtedness with respect to the Securities of any
series may, at any time and from time to time, without the consent of or notice
to the Trustee or the Holders of Securities of such series, without incurring
responsibility to such Holders and without impairing or releasing the
subordination provided in this Article 18 or the obligations hereunder of the
Holders of the Securities of such series to the holders of such Guarantor Senior
Indebtedness, do any one or more of the following:  (i) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, such
Guarantor Senior Indebtedness, or otherwise amend or supplement in any manner
such Guarantor Senior Indebtedness or any instrument evidencing the same or any
agreement under which such Guarantor Senior Indebtedness is outstanding; (ii)
sell, exchange, release or otherwise deal with any property pledged, mortgaged
or otherwise securing such Guarantor Senior Indebtedness; (iii) release any
Person liable in any manner for the collection of such Guarantor Senior
Indebtedness; and (iv) exercise or refrain from exercising any rights against
the Guarantor and any other Person.

Trustee in the Borough of Manhattan, the City of New York; provided, however,
that payment of interest may be made at the option of the Company by check
mailed to the Holder at such address as shall appear in the Securities Register.
Notwithstanding the foregoing, so long as the Holder of any Subordinated Notes

any Additional Interest, if any) on such Subordinated Notes held by the Property
Trustee will be made at such place and to such account as may be designated by
the Property Trustee.

     (8)  A holder of Subordinated Notes may transfer or exchange Subordinated
Notes held by it only in minimum denominations of $100,000 and integral
multiples of $1,000 in excess thereof, and only if such transfer or exchange
does not result in such holder's holding Subordinated Notes in a denomination of
less than $100,000.  Any attempted transfer, sale or other disposition of
Subordinated Notes in a denomination of less than $100,000 shall be deemed to be
void and of no legal effect whatsoever.

Restrictions on Transfers; Depository.  (a)  If distributed to holders of
Preferred Securities in connection with a Dissolution Event, the Subordinated

Subordinated Notes replace in accordance with the following procedures.

          (1)     If the Preferred Securities are held in global form, the
     Subordinated Notes shall be presented to the Trustee by the Property
     Trustee in exchange for a Security in permanent global form in an aggregate
     principal amount equal to the aggregate principal amount of all outstanding
     Subordinated Notes (a "Global Subordinated Note"), to be registered in the
     name of the Depository, or its nominee, and delivered by the Property
     Trustee to the Depository for crediting to the accounts of its participants
     pursuant to the instructions of the Administrative Trustees. The Company
     upon any such presentation shall execute a Global Subordinated Note in such
     aggregate principal amount and deliver the same to the Trustee for
     authentication and delivery in accordance with the Indenture. Payments on
     the Subordinated Notes issued as a Global Subordinated Note will be made to
     the Depository. The Company initially appoints The Depository Trust Company
     to act as Depository with respect to the Global Subordinated Note.

          (2)     If the Preferred Securities are held in certificated form, the
     Subordinated Notes shall be presented to the Trustee by the Property


                                       8

     Trustee and each outstanding Preferred Security certificate will be deemed
     to represent a beneficial interest in such Subordinated Note in an
     aggregate principal amount equal to the aggregate Liquidation Amount of the
     Preferred Securities represented by such Preferred Security certificate.
     When the holder of a Preferred Security certificate presents such
     certificate for transfer or reissuance, such certificate will be canceled
     and a Subordinated Note, registered in the name of such holder or such
     holder's transferee, as the case may be, in an aggregate principal amount
     equal to the aggregate Liquidation Amount of the canceled certificate, will
     be executed by the Company and delivered to the Trustee for authentication
     and delivery in accordance with the Indenture. On issue of such
     Subordinated Notes, Subordinated Notes with an equivalent aggregate
     principal amount that were presented by the Property Trustee to the Trustee
     will be deemed to have been canceled.

     (9)   Any Global Subordinated Note may be endorsed with or have
incorporated in the text thereof such legends or recitals or changes not
inconsistent with the provisions of this Indenture as may be required by the
Depository, by a national securities exchange or by the National Association of
Securities Dealers, Inc. in order for the Subordinated Notes to be tradeable on
the PORTAL Market or as may be required for the Subordinated Notes to be
tradeable on any other market developed for trading of securities pursuant to
Rule 144A or required to comply with any applicable law or any regulation
thereunder or with the rules and regulations of any securities exchange upon
which the Subordinated Notes may be listed or traded or to conform with any
usage with respect thereto, or to indicate any special limitations or
restrictions to which any particular Subordinated Notes are subject.

     (10)  Each Subordinated Note that bears or is required to bear the legend
set forth in this Section 2.4(c) (a "Restricted Security") shall be subject to
the restrictions on transfer provided in the legend set forth in this Section
2.4(c), unless such restrictions on transfer shall be waived by the written
consent of the Company, and the Holder of each Restricted Security, by such
Holder's acceptance thereof, agrees to be bound by such restrictions on
transfer. As used in this Section 2.4(c) and in Section 2.4(d), the term
"transfer" encompasses any sale, pledge, transfer or other disposition of any

     SECURITIES ACT, AND (3) AGREES THAT IT WILL DELIVER TO EACH
     PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED A

     OF THE HOLDING PERIOD APPLICABLE TO THE SALE OF THE SECURITY
     EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT.

     Following the Transfer Restriction Termination Date, any Subordinated Note
or security issued in exchange or substitution therefor (other than Subordinated
Notes acquired by the Company or any Affiliate), may upon surrender of such
Subordinated Note or security for exchange to the Trustee in accordance with the
provisions of this Section 2.4, be exchanged for a new Subordinated Note or
Subordinated Notes, of like tenor and aggregate principal amount, which shall
not bear the restrictive legend required by this Section 2.4(c).

     (11) Any Subordinated Note that, prior to the Transfer Restriction
Termination Date, is purchased or owned by the Company or any Affiliate thereof
may not be resold by the Company or such Affiliate unless registered under the
Securities Act or resold pursuant to an exemption from the registration

"restricted security" as defined under Rule 144 under the Securities Act.

     (12) Except as provided in (f) below, a Global Subordinated Note may be
transferred, in whole but not in part, only to another nominee of the

<PAGE>

Notes in definitive registered form without coupons, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Subordinated Notes in exchange for such Global Subordinated
Notes. In addition, upon an Event of Default or if the Company may at any time
determine that the Subordinated Notes shall no longer be represented by a Global
Subordinated Note, in such event the Company will execute and the Trustee, upon
receipt of an Officers' Certificate evidencing such determination by the Company
and an Company Order, will authenticate and make available for delivery the
Subordinated Notes in definitive registered form without coupons, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Subordinated Note for such Subordinated Notes in definitive
registered form without coupons, in authorized denominations, the Global
Subordinated Note shall be canceled by the Trustee. Such Subordinated Notes
shall be registered in such names and in such authorized denominations as the

     points;

          (2) from and including the Remarketing Settlement Date on which

     amount is paid, the Winning Bid Rate; and

          (3) notwithstanding clauses (i) and (ii) above, if the Company fails
     to pay the principal amount on the date such amount becomes due, then from
     and including such due date to but excluding the date such principal amount
     is paid, the applicable periodic Interest Rate, compounded quarterly, but
     only to the extent permitted by applicable law.

     Interest that is not paid when due will bear additional interest thereon
compounded quarterly at the applicable periodic Interest Rate specified above
(to the extent permitted by applicable law) in accordance with Section 4.1. The
term

                                       12
<PAGE>

"interest", as used herein, includes any such Additional Interest unless
otherwise stated.

     (14) Until the Remarketing Settlement Date on which Replacement Notes are
issued, interest on the Subordinated Notes will be payable quarterly in arrears

1999, and on such Remarketing Settlement Date (each, a "Pre-Remarketing Interest
Payment Date"), will accrue from and including the most recent date to which
interest has been paid or, if no interest has been paid, from June 30, 1999, to
but excluding the related Pre-Remarketing Interest Payment Date, except as
otherwise described below.

     The Interest Rate in effect for the period from and including the Closing
Date to but excluding October 1, 1999 shall be the rate determined by the
Calculation Agent two London Banking Days prior to Closing Date and shall equal
LIBOR plus 125 basis points. The Interest Rate in effect thereafter, for each
quarterly period from and including the immediately preceding Pre-Remarketing
Interest Payment Date to but excluding the applicable Pre-Remarketing Interest
Payment Date, shall be determined by the Calculation Agent two London Banking
Days prior to such immediately preceding Pre-Remarketing Interest Payment Date
(a "Date of Determination") and shall equal LIBOR plus 125 basis points. Prior
to the Remarketing Settlement Date, the amount of interest payable for any
period shall be computed on the basis of a 360-day year and the actual number of
days elapsed in such period. If a Pre-Remarketing Interest Payment Date is not a
Business Day, then such Pre-Remarketing Interest Payment Date will be the next
succeeding Business Day, except if such Business Day is in the next succeeding
calendar month, such Pre-Remarketing Distribution Date will be the immediately
preceding Business Day.

     (15) Interest shall be paid to the Person in whose name such Subordinated
Note or any predecessor Subordinated Note is registered on the books and records
of the Company at the close of business on the Regular Record Date for such
interest installment, which shall be fifteen (15) days prior to a Pre-
Remarketing Interest Payment Date (the "Pre-Remarketing Regular Record Date").

     (16) From and including the Remarketing Settlement Date on which
Replacement Notes are issued, interest on the Replacement Notes will be
cumulative and payable quarterly in arrears on July 1, October 1, January 1 and
April 1 of each year, commencing on the Remarketing Settlement Date, and on the
Maturity Date (each, an "Interest Payment Date"), will accumulate from the most
recent date to which interest has been paid or, if no interest has been paid,

                                       13
<PAGE>

from and including the Remarketing Settlement Date, to but excluding the related
Interest Payment Date, except as otherwise described below. From and including
the Remarketing Settlement Date, the amount of interest payable for any
quarterly period shall be computed on the basis of a 360-day year of twelve 30-
day months. Except as provided in the last sentence of this paragraph, from and
including the Remarketing Settlement Date the amount of interest payable for any
period shorter than a full quarterly period for which interest is computed will
be computed on the basis of the actual number of days elapsed per 30-day month.
If an Interest Payment Date is not a Business Day, then such Interest Payment
Date will be postponed to the next succeeding Business Day (and without any
interest or other payment in respect of any such delay).

     (17) Interest shall be paid to the Person in whose name the Subordinated
Note or any predecessor Subordinated Note is registered on the books and records
of the Company, at the close of business on the Regular Record Date for such
interest installment, which, in respect of Subordinated Notes of which the
Property Trustee is the Holder and the related Preferred Securities are in book-
entry only form or a Global Subordinated Note, shall be the close of business on
the Business Day next preceding that Interest Payment Date (the "Regular Record
Date"). If the Subordinated Notes are not represented by a Global Subordinated
Note, the Regular Record Date for such interest installment shall be fifteen
(15) days prior to that Interest Payment Date.

     (18) In the event that (i) the Property Trustee is the Holder of all of the
outstanding Subordinated Notes, (ii) a Tax Event in respect of the Trust shall
have occurred and be continuing and (iii) the Company shall not have (A)
redeemed the Subordinated Notes pursuant to Section 3.1 or (B) terminated the
Trust pursuant to Section 8.01(iii) of the Trust Agreement, the Company shall
pay to the Trust (or its permitted successors or assigns under the Trust
Agreement) for so long as the Trust (or its permitted successor or assignee) is
the registered holder of the Subordinated Notes, such additional amounts as may
be necessary in order that the amount of distributions (including any Additional
Amounts as defined in the Trust Agreement) then due and payable by the Trust on
the Preferred Securities and Common Securities that at any time remain
outstanding in accord with the terms thereof shall not be reduced as a result of
any Additional Taxes (the "Additional Sums"). Whenever in this Indenture or the
Subordinated Notes there is a reference in any context to the payment of
principal of or interest on the Subordinated Notes, such mention shall be deemed
to include mention of the payments of the Additional Sums provided for in this
paragraph to the extent that, in such context, Additional Sums are, were or
would be payable in respect thereof pursuant to the provisions of this paragraph
and express mention of the payment of Additional Sums (if applicable) in any
provisions hereof shall not be construed

                                       14
<PAGE>

as excluding Additional Sums in those provisions hereof where such express
mention is not made; provided that the extension of an interest payment period
pursuant to Section 4.1 on the Subordinated Notes shall not extend the payment
of any Additional Sums that may be due and payable during such interest payment
period.

     Section 2.6. Right to Proceed. The Company acknowledges the rights of the
Holders of Preferred Securities under the Trust Agreement to take Direct Action
referred to in Section 3.08(e) thereof and Annex I thereto.

     Section 2.7. No Issuance Upon the Exercise of Warrants. The Subordinated
Notes shall not be issuable upon the exercise of warrants.

                     REDEMPTION OF THE SUBORDINATED NOTES

     Section 3.1. Redemption. If at any time a Special Event occurs, the Company
shall have the right (subject to the conditions set forth in the Indenture) at
any time, upon not less than 30 nor more than 60 days notice, to redeem the
Subordinated Notes in whole or in part within the 90 days following the
occurrence of such Special Event (the "90 Day Period") at a redemption price
equal to 100% of the principal amount of the Subordinated Notes plus any accrued
and unpaid interest thereon (including any Additional Interest) to the date of
such redemption (the "Redemption Price"), and, simultaneous with such
redemption, to cause a Like Amount of the Trust Securities to be redeemed by the
Trust at the Mandatory Redemption Price on a Pro Rata basis. The Redemption
Price shall be paid prior to 12:00 noon, New York City time, on the date of such
redemption or such earlier time as the Company determines, provided that the
Company shall deposit with the Trustee an amount sufficient to pay the
Redemption Price prior to the Redemption Date.

     Section 3.2. Optional Redemption by Company. Except as provided in Section
3.1, the Subordinated Notes are not entitled to any optional redemption by the
Company.

     Section 3.3. No Sinking Fund. The Subordinated Notes are not entitled to
the benefit of any sinking fund.

     Section 3.4. Mandatory Redemption upon a Qualifying Equity Offering. If at
any time a Qualifying Equity Offering occurs, the Company shall, upon not

                                       15
<PAGE>

less than 30 nor more than 60 days' notice, redeem Subordinated Notes having an
aggregate principal amount equal to the gross proceeds of such Qualifying Equity
Offering (without deduction of any applicable underwriting discounts and
commissions), on the 90th day following the closing of such Qualifying Equity
Offering, and, simultaneous with such redemption, cause a Like Amount of the
Trust Securities to be redeemed by the Trust on a Pro Rata basis at a redemption
price equal to the Redemption Price.

                                   ARTICLE 4

                     EXTENSION OF INTEREST PAYMENT PERIOD

     Section 4.1. Extension of Interest Payment Period. The Company shall have
the right, at any time during the term of the Subordinated Notes, so long as no
Event of Default has occurred and is continuing, from time to time to extend the
interest payment period for the Subordinated Notes (each such deferral period,
an "Extension Period"), during which period the Company shall have the right to
not make payments of interest on any interest payment date, and at the end of
such Extension Period the Company shall pay all interest then accrued and unpaid
thereon (together with Additional Interest thereon, if any, to the extent
permitted by applicable law) to the Person in whose name the Subordinated Note
or any predecessor Subordinated Note is registered on the books and records of
the Company at the close of business on the Regular Record Date for the Interest
Payment Date at the end of such Extension Period; provided that no such
Extension Period shall extend beyond the Mandatory Redemption Date, if the Trust
Securities are at the time outstanding, or the Maturity Date. Upon termination
of any Extension Period and upon the payment of all accrued and unpaid interest
and any Additional Interest then due, the Company may select a new Extension
Period, subject to the above requirements. No interest including Additional
Interest, if any, shall be due and payable during an Extension Period, except at
the end thereof. The Company shall give the Trustee, the Property Trustee and
the Administrative Trustees notice of its selection of such Extension Period at
least one Business Day prior to the record date for the date the distributions
on the Preferred Securities of the Trust (or if no Preferred Securities are
outstanding, for the date interest on the Subordinated Notes) would have been
payable except for the election to begin such Extension Period. Such notice
shall specify the period selected.

     The Trustee shall promptly give notice of the Company's selection of such
Extension Period to the Holders of the outstanding Subordinated Notes.

                                       16
<PAGE>

     The limitations set forth in the first paragraph of Section 3.11 of the
Base Indenture shall apply during any Extension Period.

acceptance thereof likewise covenants and agrees, that (i) all Subordinated

                            REMARKETING; RESET RATE

     Section 10.1. Effectiveness of this Article; Incorporation of Remarketing
Agreement. (a) Sections 10.2 and 10.4 shall become effective if and only if the
Subordinated Notes have been distributed to the Holders of the Trust Securities
prior to Remarketing. Notwithstanding the foregoing, on the Remarketing
Settlement Date (except in the case of a Failed Remarketing), the certificates
representing the Subordinated Notes held by the Property Trustee shall be
exchanged for certificates representing Replacement Notes.

     (24) Every Person, by virtue of having become a Holder in accordance with
the terms of this Agreement, shall be deemed to have expressly assented and
agreed to the terms of, and shall be bound by, this First Supplemental
Indenture, including the terms of Exhibit B. Exhibit B is hereby incorporated in
and expressly made a part of this First Supplemental Indenture.

     Section 10.2. Determination of Reset Date; Remarketing Procedures.

     (25) (i) Subject to Section 10.4, if the Closing Price of the Ordinary
Shares on any Trading Day is less than the Trigger Price and the Subordinated
Notes have been distributed to the holders of the Trust Securities (a "Trigger
Event"), the holders of a majority in principal amount of the Subordinated Notes
(the "Requesting Holders") will have the option to require remarketing of the
Subordinated Notes. The Requesting Holders may exercise this option by giving
notice in writing to the Remarketing Agent who shall immediately give notice in
writing to the Company on their behalf (a "Remarketing Notice") at any time
prior to the sixth Business Day following the date such Trigger Event occurs. If

                                       20
<PAGE>

the Requesting Holders exercise their option to require the remarketing of the
Subordinated Notes, the Reset Date shall be the sixth Business Day after the
date on which the Remarketing Notice is given by the Remarketing Agent (the
"Expected Reset Date").

          (ii)   If the Requesting Holders do not exercise their option to
     require the remarketing the Subordinated Notes, pursuant to Section
     10.2(a)(i) above with respect to any Trigger Event, the Requesting Holders
     shall continue to have the option to require the remarketing of the
     Subordinated Notes, in accordance with Section 10.2(a)(i) with respect to
     any subsequent Trigger Event.

          (iii)  Notwithstanding Section 10.2(a)(i):

                    (A)  the Guarantor may, by notice to the Remarketing Agent,
          direct that the Reset Date be delayed if the Company believes it will
          be unable to meet the conditions to Remarketing in the absence of such
          a delay; and

                    (B)  the Remarketing Agent may, by notice to the Company,
          direct that the Reset Date be delayed if the Remarketing Agent
          believes that a Remarketing will not be successful in the absence of
          such a delay,

     provided that the Guarantor and the Remarketing Agent, in either such
     event, will use their reasonable best efforts to establish a delayed Reset
     Date that is within five Business Days after the Expected Reset Date, but
     in no event later than the 15th Business Day following the date on which
     the related Remarketing Notice was delivered, or the 20th Business Day in
     the case of a Renewed Remarketing to which the provisions of Section 10.4
     apply (as applicable, the "Final Reset Date").

          (iv)   If the Guarantor and the Remarketing Agent have not agreed, on
     or prior to the sixth Business Day preceding the Final Reset Date, to a
     Reset Date that is not later than the Final Reset Date, a Failed
     Remarketing shall be deemed to have occurred.

     (26) The Guarantor shall, by notice to the Remarketing Agent no later than
five Business Days prior to the Reset Date, select and specify five Reference
Corporate Dealers.  By 3:00 p.m., New York City time, on the Reset Date, the
Remarketing Agent shall request Bids from such Reference Corporate Dealers. The
Remarketing Agent or an Affiliate or Associated Person thereof (any such

                                       21
<PAGE>

person, an "Affiliated Bidder") may, at its option, enter a Bid. The Remarketing
Agent shall disclose to the Guarantor the Bids obtained and determine the lowest
Bid Rate from among the Bids obtained on the Reset Date (the "Winning Bid
Rate"). By approximately 4:30 p.m., New York City time, on the Reset Date, the
Remarketing Agent shall notify the Trustee and the Property Trustee of the
Winning Bid Rate. If on a Reset Date, Bids are not submitted by at least two
Reference Corporate Dealers, or if the lowest Bid submitted would result in a
Winning Bid Rate in excess of the rate permitted by applicable law, such
Remarketing shall be deemed to be a Failed Remarketing on the corresponding
Remarketing Settlement Date. The Winning Bid Rate determined by the Remarketing
Agent, absent manifest error, shall be binding and conclusive upon the holders
of the Subordinated Notes, the Company, the Guarantor and the Trust.

     (27) On the Reset Date, the Remarketing Agent shall designate as the
Secondary Purchaser (the "Secondary Purchaser") the Reference Corporate Dealer
providing the Bid containing the Winning Bid Rate.  If the Winning Bid Rate is
specified in the Bids submitted by two or more bidders, the Remarketing Agent
shall, in consultation with the Company, designate one of such bidders as the
Secondary Purchaser.

     (28) On the Reset Date, the Secondary Purchaser shall enter into a
Secondary Purchase Agreement for the purchase by such Secondary Purchaser at the
Remarketing Price of the aggregate principal amount of Subordinated Notes, with
an Interest Rate equal to the Winning Bid Rate and with a Mandatory Redemption
Date (or, in the case of Subordinated Notes, a Maturity Date) on the Remarketed
Maturity Date.

     (29) If a Remarketing has occurred pursuant to this Section 10.2 but
settlement of the purchase and sale of the Subordinated Notes, does not occur on
the corresponding Remarketing Settlement Date, then, unless the provisions of
Section 10.4 with respect to a Renewed Remarketing shall apply, a Failed
Remarketing shall be deemed to occur on such Remarketing Settlement Date.

     (30) At the time and in the manner specified in the Secondary Purchase
Agreement, the Secondary Purchaser shall pay to the Remarketing Agent on behalf
of the Holders of the Subordinated Notes, on the Remarketing Settlement Date, an
amount of cash equal to the Remarketing Price.

     (31) Unless otherwise agreed among the Remarketing Agent, the Paying Agent
and any Former Holder, the Remarketing Agent shall promptly pay the Remarketing
Price, less the Remarketing Fee, to the Paying Agent, acting solely as agent for
the Former Holders, and the Paying Agent shall pay such

                                       22
<PAGE>

amount to the Former Holders in the same manner as is specified in Section 2.7
of the Base Indenture for payments of interest and otherwise herein, except that
the record date therefor shall be the Business Day immediately preceding the
Remarketing Settlement Date.

     (32) The obligation of the Remarketing Agent to make payment to the Former
Holders in connection with the Remarketing shall be limited to the extent that
the Secondary Purchaser has delivered the Remarketing Price therefor to the
Remarketing Agent.

     (33) Any outstanding Preferred Securities (or, if applicable, the
Subordinated Notes) purchased on the Remarketing Settlement Date shall be deemed
to be transferred to the Secondary Purchaser and shall be replaced in the manner
provided in Section 10.2(j).  On and after the Remarketing Settlement Date
(except in the event of a Failed Remarketing), the Company shall make no further
payments to, and the Company shall have no further obligations under First
Supplemental Indenture (or the Indenture) in respect of, the Holders of such
replaced Subordinated Notes (the "Former Holders"),  the Company shall only be
obligated to make payments to the Holders of Replacement Notes and the of the
Former Holders shall no longer represent an obligation of the Company, but shall
only represent a right to receive the proceeds of the Remarketing from the
Paying Agent.

     (34) The Company shall cause replacement certificates evidencing the
remarketed Subordinated Notes (or, if the Preferred Securities have been
remarketed, reset Subordinated Notes) to be executed by the Company and
authenticated by the Trustee in accordance with the provisions of Section 3.3 of
the Base Indenture (the "Replacement Notes").  The Replacement Notes shall be
delivered to the purchaser or purchasers of the remarketed Subordinated Notes in
accordance with the terms of the Secondary Purchase Agreement.

     Section 10.3.  Reset of Interest Rate and Maturity Date. From and including
the Remarketing Settlement Date on which Replacement Securities are issued, if
the Subordinated Notes are remarketed pursuant to Article 10 hereof or the
Preferred Securities are remarketed pursuant to Article 6 of the Trust
Agreement, the Interest Rate on the Subordinated Notes shall be the Winning Bid
Rate and the Maturity Date shall be the Remarketed Maturity Date.

     Section 10.4.  Renewed Remarketing.  If a Remarketing has occurred pursuant
to Section 10.2 that would be a Failed Remarketing pursuant to Section 10.2(e),
because the purchase and sale of the Subordinated Notes do not take place on the
corresponding Remarketing Settlement Date, and the reason for such

                                       23
<PAGE>

failure shall, in the good faith determination of the Remarketing Agent (made
after consultation with the Guarantor), result from facts or circumstances that
are not due to the action or inaction of the Guarantor, then the provisions of
Section 10.2 shall apply to a second remarketing (a "Renewed Remarketing") of
the Preferred Securities (or, if applicable, the Subordinated Notes), except
that the Expected Reset Date shall be the sixth Business Day following such
corresponding Remarketing Settlement Date; provided however that upon the
occurrence of a Failed Remarketing pursuant to Section 10.2, only one Renewed
Remarketing can occur pursuant to this Section 10.4, and no Renewed Remarketing
shall occur after the Final Reset Date.

     Section 10.5.  Failed Remarketing. The Remarketing Agent shall give notice
of any Failed Remarketing on the date such Failed Remarketing occurs, or is
deemed to occur, by 4:00 p.m., New York City time, on the date of such Failed
Remarketing, to the Guarantor, the Trustee and the Paying Agent under the
Indenture.

     ACE INA Holdings Inc., a Delaware corporation (the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay the principal sum of ___________
dollars ($___________) on the Maturity Date.

     (35) Interest on the principal amount of this Subordinated Note will accrue
and be payable at a rate (the "Interest Rate") per annum equal to

          (1)  from and including the Closing Date to but excluding the date on
     which the principal amount of this Subordinated Note becomes due upon the
     maturity, acceleration or redemption thereof, LIBOR plus 125 basis points;

          (2)  except as provided in clause (iii) below, from and including the
     Remarketing Settlement Date on which Replacement Notes are issued to but
     excluding the date on which the principal amount of the Subordinated Notes
     becomes due upon the maturity, acceleration or redemption thereof, the
     Winning Bid Rate; and

          (3)  if the Company fails to pay the principal amount due upon the
     maturity, acceleration or redemption of this Subordinated Notes on the date
     such amount becomes due, from and including such due date to but excluding
     the date of actual payment by the Company, the applicable periodic Interest
     Rate compounded quarterly.

     Interest that is not paid when due will bear additional interest thereon
compounded quarterly at the applicable periodic Interest Rate (to the extent
permitted by applicable law).

     The term "interest", as used herein, includes any Additional Interest
unless otherwise stated.

     (36) Until the Remarketing Settlement Date on which Replacement Notes are
issued, interest on this Subordinated Note will be payable quarterly (subject to
deferral as set forth herein) in arrears on July 1, October 1, January 1 and
April 1 of each year, commencing October 1, 1999, and on such Remarketing

                                     A1-1

Settlement Date (each, a "Pre-Remarketing Interest Payment Date"), will
accumulate from and including the most recent date to which interest has been
paid or, if no interest has been paid, from June 30, 1999, to but excluding the
related Pre-Remarketing Interest Payment Date, except as otherwise described
below.

     The Interest Rate in effect for the period from and including the Closing
Date to but excluding October 1, 1999 shall be the rate determined by the
Calculation Agent two London Banking Days prior to the Closing Date and shall
equal LIBOR plus 125 basis points.  The Interest Rate in effect thereafter, for
each quarterly period from and including the immediately preceding Pre-
Remarketing Interest Payment Date to but excluding the applicable Pre-
Remarketing Interest Payment Date, shall be determined by the Calculation Agent
two London Banking Days prior to such immediately preceding Pre-Remarketing
Interest Payment Date (a "Date of Determination") and shall equal LIBOR plus 125
basis points.  Prior to the Remarketing Settlement Date, the amount of interest
payable for any period shall be computed on the basis of a 360-day and the
actual number of days elapsed in such period.  If a Pre-Remarketing Interest
Payment Date is not a Business Day, then such Pre-Remarketing Interest Payment
Date will be the next succeeding Business Day, except if such Business Day is in
the next succeeding calendar month, such Pre-Remarketing Distribution Date will
be the immediately preceding Business Day.

     As used herein, "London Banking Day" means any day on which dealings in
deposits in U.S. Dollars are transacted in the London interbank market.

     All percentages resulting from any calculations on the Subordinated Notes
will be rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point, with five one-millionths of a percentage point rounded upward
(e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and
all dollar amounts used in or resulting from such calculations will be rounded
to the nearest cent (with one-half cent being rounded upward).

     (37) From and including the Remarketing Settlement Date on which
Replacement Notes are issued, interest on the Replacement Notes will be payable
quarterly in arrears on July 1, October 1, January 1 and April 1 of each year,
commencing on the Remarketing Settlement Date, and on the Maturity Date (each,
an "Interest Payment Date"), will accumulate from the most recent date to which
interest has been paid or, if no interest has been paid, from and including the
Remarketing Settlement Date, to but excluding the related Interest Payment Date,
except as otherwise described below. From and including the Remarketing

                                     A1-2
<PAGE>

Settlement Date, the amount of interest payable for any period shall be computed
on the basis of a 360-day year of twelve 30-day months. Except as provided in
the last sentence of this paragraph, from and including the Remarketing
Settlement Date the amount of interest payable for any period shorter than a
full quarterly period for which interest is computed will be computed on the
basis of the actual number of days elapsed per 30-day month. If an Interest
Payment Date is not a Business Day, then such Interest Payment Date will be
postponed to the next succeeding Business Day (and without interest or other
payment in respect of any such delay).

     (d)  Interest shall be paid to the Person in whose name this Subordinated
Note or any predecessor Subordinated Note is registered on the books and records
of the Company at the close of business on the Regular Record Date for such
interest installment, which shall be fifteen (15) days prior to a Pre-
Remarketing Interest Payment Date (the "Pre-Remarketing Regular Record Date").
Notwithstanding the foregoing, so long as the Holder of this Subordinated Note
is the Property Trustee, the payment of the principal of (and premium, if any)
and interest on this Subordinated Note will be made at such place and to such
account as may be designated by the Property Trustee.

     The indebtedness evidenced by this Subordinated Note is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all existing and future Senior Indebtedness and the
prior payment of other Securities to the extent provided for in the First
Supplemental Indenture, and this Subordinated Note is issued subject to the
provisions of the Indenture with respect thereto. Each Holder of this
Subordinated Note, by accepting the same, (a) agrees to and shall be bound by
such provisions, (b) authorizes and directs the Trustee on his or her behalf to
take such action as may be necessary or appropriate to acknowledge or effectuate
the subordination so provided and (c) appoints the Trustee his or her attorney-
in-fact for any and all such purposes.  Each Holder hereof, by his or her
acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder of
Senior Indebtedness, whether now outstanding or hereafter incurred, and waives
reliance by each such holder upon said provisions.

     This Subordinated Note shall not be entitled to any benefit under the
Indenture hereinafter referred to, be valid or become obligatory for any purpose
until the certificate of authentication hereon shall have been signed by or on
behalf of the Trustee.

                           [FORM OF REVERSE OF NOTE]

     This Subordinated Note is one of a duly authorized series of Securities of
the Company (herein sometimes referred to as the "Subordinated Notes"),
specified in the Base Indenture, all issued or to be issued in one or more
series under and pursuant to an Indenture dated as of June 15, 1999, duly
executed and delivered between the Company, ACE Limited (the "Guarantor") and
The First National Bank of Chicago, as Trustee (the "Trustee"), as supplemented
by the First Supplemental Indenture dated as of June 30, 1999, between the
Company, the Guarantor and the Trustee (the Base Indenture as so supplemented,
the "Indenture"), to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company, the
Guarantor and the Holders of the Subordinated Notes.  By the terms of the
Indenture, the Subordinated Notes are issuable thereunder in series that may
vary as to amount, date of maturity, rate of interest and in other respects as
provided in the Indenture. This series of Subordinated Notes is limited in
aggregate principal amount as specified in said First Supplemental Indenture and
herein sometimes referred to as the "Subordinated Notes."

     Because of the occurrence and continuation of a Special Event, a Qualifying
Equity Offering, in certain circumstances, this Subordinated Note may become due
and payable at the principal amount together with any interest accrued thereon
(including Additional Interest) (the "Redemption Price"). The Redemption Price
shall be paid prior to 12:00 noon, New York City time, on the date of such
redemption or at such earlier time as the Company determines.  If the Maturity
Date or any other date fixed for redemption of the Subordinated Notes is not a
Business Day, then payment of the Redemption Price or principal payable on such
date will be made on the next succeeding day that is a Business Day with
interest thereon to the date of payment; provided that the Company may elect to
make such payment on the immediately preceding day that is a Business Day.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Subordinated Notes may
be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions permitting the Company, the Guarantor and
the Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Subordinated Notes and each other series of
Securities Outstanding and affected, to execute supplemental indentures for the
purpose of adding any provisions to or changing in any manner or eliminating any

                                     A1-7
<PAGE>

of the provisions of the Indenture or of modifying in any manner the rights of
the Holders of such Series of Securities; provided that the Company, the
Guarantor and the Trustee may not, without the consent of the Holder of each
Subordinated Note then Outstanding and affected thereby:  (a) change the time of
payment of the principal (or any installment) of any Subordinated Note, or
reduce the principal amount thereof, or reduce the rate or change the time of
payment of interest thereon, or impair the right to institute suit for the
enforcement of any payment on any Subordinated Note when due or (b) reduce the
percentage in principal amount of the Subordinated Notes.  The Indenture also
contains provisions providing that prior to the acceleration of the maturity of
any Subordinated Note, the Holders of a majority in aggregate principal amount
of Subordinated Notes may, on behalf of the Holders of all Subordinated Notes,
waive any past default with respect to the Subordinated Notes and its
consequences, except a default (i) in respect of a covenant or provision of the
Indenture or of any Subordinated Note which cannot be modified or amended
without the consent of the Holder of each Outstanding Subordinated Note or (ii)
in the payment of the principal of, any premium or interest (including any
Additional Interest) on, or any Additional Amounts with respect to the
Subordinated Notes.

     No reference herein to the Indenture and no provision of this Subordinated
Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and premium, if
any, and interest on this Subordinated Note at the time and place and at the
rate and in the money herein prescribed.

     The Company shall have the right at any time during the term of this
Subordinated Note, from time to time, to extend the interest payment period of
such Subordinated Note (each such deferral period an "Extension Period"), during
which periods the Company shall have the right not to make payments of interest
on any interest payment date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest, if any,
thereon to the extent permitted by applicable law) to the Person in whose name
such Subordinated Note or any predecessor Subordinated Note is registered on the
books and records of the Company at the close of business on the Regular Record
Date.  Prior to the termination of any such Extension Period, the Company may
further extend the interest payment period, provided that no Extension Period
shall extend beyond the Mandatory Redemption Date, if the Trust Securities are
at the time outstanding, or the Maturity Date of this Subordinated Note.  Upon
the termination of any such Extension Period and upon the payment of all accrued
and unpaid interest and any Additional Interest then due, the Company may elect
to being a new Extension Period.

     As provided in the Indenture and subject to certain limitations herein and
therein set forth, this Subordinated Note is transferable by the registered
Holder hereof on the Securities Register of the Company, upon surrender of this
Subordinated Note for registration of transfer at the office or agency of the
Trustee in the City and State of New York accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company or the Trustee duly
executed by the registered Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Subordinated Notes of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

     Prior to due presentment for registration of transfer of this Subordinated
Note, the Company, the Guarantor, the Trustee, any paying agent and the
Securities Registrar may deem and treat the registered holder hereof as the
absolute owner hereof (whether or not this Subordinated Note shall be overdue
and notwithstanding any notice of ownership or writing hereon made by anyone
other than the Securities Registrar) for the purpose of receiving payment of or
on account of the principal hereof and premium, if any, and interest due hereon
and for all other purposes, and neither the Company nor the Guarantor nor the
Trustee nor any paying agent nor any Securities Registrar shall be affected by
any notice to the contrary.

     No recourse shall be had for the payment of the principal of or the
interest on this Subordinated Note, or for any claim based hereon, or otherwise
in respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

     The Subordinated Notes of this series are issuable only in registered form
without coupons in denominations of $100,000 and any integral multiple of $1,000
thereof.  A holder of Subordinated Notes may transfer or exchange Subordinated
Notes held by it only in minimum denominations of $100,000 and integral
multiples of $1,000 in excess thereof, and only if such transfer or exchange
does not result in such holder's holding Subordinated Notes in a denomination of
less than $100,000.  Any attempted transfer, sale or other

<PAGE>

disposition of Subordinated Notes in a denomination of less than $100,000 shall
be deemed to be void and of no legal effect whatsoever.

     All terms used in this Subordinated Note that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

THE INDENTURE AND THE SUBORDINATED NOTES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS
PRINCIPLES OF CONFLICTS OF LAWS.

Note is a Global Security within the meaning of the Indenture hereinafter
referred to and is registered in the name of a Depository or a nominee of a
Depository. This Note is exchangeable for Subordinated Notes registered in the
name of a person other than the Depository or its nominee only in the limited
circumstances described in the Indenture, and no transfer of this Note (other
than a transfer of this Note as a whole by the Depository to a nominee of the
Depository or by a nominee of the Depository to the Depository or another
nominee of the Depository) may be registered except in limited circumstances.

its agent for registration of transfer, exchange or payment, and any Note issued
is registered in the name of Cede & Co. or such other name as requested by an
authorized representative of The Depository Trust Company and any payment hereon
is made to Cede & Co., ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY A PERSON IS WRONGFUL since the registered owner hereof, Cede & Co.,
has an interest herein.

EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933,

EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE
HOLDER (1) REPRESENTS THAT IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED
IN RULE 144A UNDER THE SECURITIES ACT), (2) AGREES THAT IT WILL NOT PRIOR TO THE
EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE SECURITY EVIDENCED
HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION)
RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY EXCEPT (A) TO ACE

COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, AND (3) AGREES THAT IT WILL
DELIVER TO EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED A
NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AT THE REQUEST OF THE HOLDER,

     ACE INA Holdings Inc., a Delaware corporation (the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay the principal sum of ____________
dollars ($__________) on the Maturity Date.

     Interest on the principal amount of this Subordinated Note will accrue and
be payable at a rate (the "Interest Rate") per annum equal to from and including
the date of issuance to but excluding the date such principal amount is paid,
the Winning Bid Rate, compounded quarterly; and if the Company fails to pay the
principal amount on the date such amount becomes due, then from and including
such due date to but excluding the date such principal amount is paid, the
applicable periodic Interest Rate, compounded quarterly, but only to the extent
permitted by applicable law.

     Interest that is not paid when due will bear additional interest thereon
compounded quarterly at the applicable periodic Interest Rate (to the extent
permitted by applicable law).

     The term "interest", as used herein, includes any Additional Interest
unless otherwise stated.

     From and including the date of issuance, interest on this Replacement Note,
will be payable quarterly in arrears on July 1, October 1, January 1 and April 1
of each year, commencing on the Remarketing Settlement Date, and on the Maturity
Date (each, an "Interest Payment Date"), will accumulate from the most recent
date to which interest has been paid or, if no interest has been paid, from and
including the date of issuance, to but excluding the related Interest Payment
Date, except as otherwise described below.  The amount of interest payable for
any period shall be computed on the basis of a 360-day year of twelve 30-day
months. Except as provided in the last sentence of this paragraph, the amount of
interest payable for any period shorter than a full quarterly period for which
interest is computed will be computed on the basis of the actual number of days
elapsed per 30-day month. If an Interest Payment Date is not a Business Day,

                                     A2-3

any predecessor Subordinated Note is registered on the books and records of the
Company at the close of business on the Regular Record Date for such interest
installment, which, in respect of  Subordinated Notes of which the Property
Trustee is the Holder and the related Preferred Securities are in book-entry
only form or  a Global Subordinated Note, shall be the close of business on the
Business Day next preceding that Interest Payment Date (the "Regular Record
Date").  If the Subordinated Notes are not represented by a Global Subordinated
Note, the Regular Record Date for such interest installment shall be fifteen
(15) days prior to an Interest Payment Date.  Notwithstanding the foregoing, so
long as the Holder of this Subordinated Note is the Property Trustee, the
payment of the principal of (and premium, if any) and interest on this
Subordinated Note will be made at such place and to such account as may be
designated by the Property Trustee.

provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all existing and future Senior Indebtedness and the
prior payment of other Securities to the extent provided for in the First

     This Subordinated Note is one of a duly authorized series of Securities of
the Company (herein sometimes referred to as the "Subordinated Notes"),
specified in the Base Indenture (as defined below), all issued or to be issued
in one or more series under and pursuant to an Indenture (the "Base Indenture")
dated as of June 15, 1999, duly executed and delivered between the Company, ACE
Limited (the "Guarantor") and The First National Bank of Chicago, as Trustee
(the "Trustee"), as supplemented by the First Supplemental Indenture dated as of

Indenture as so supplemented, the "Indenture"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company, the Guarantor and the Holders of the Subordinated
Notes.  By the terms of the Indenture, the Subordinated Notes are issuable
thereunder in series that may vary as to amount, date of maturity, rate of
interest and in other respects as provided in the Indenture. This series of
Subordinated Notes is limited in aggregate principal amount as specified in said
First Supplemental Indenture and herein sometimes referred to as the
"Subordinated Notes."

     Because of the occurrence and continuation of a Special Event or a
Qualifying Equity Offering in certain circumstances, this Subordinated Note may
become due and payable at the principal amount together with any interest
accrued thereon (including Additional Interest) (the "Redemption Price"). The
Redemption Price shall be paid prior to 12:00 noon, New York City time, on the
date of such redemption or at such earlier time as the Company determines. If
the Maturity Date or any other date fixed for redemption of the Subordinated
Notes is not a Business Day, then payment of the Redemption Price or principal
payable on such date will be made on the next succeeding day that is a Business
Day with interest thereon to the date of payment; provided that the Company may
elect to make such payment on the immediately preceding day that is a Business
Day.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Subordinated Notes may
be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions permitting the Company, the Guarantor and
the Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Subordinated Notes and each other series of
Securities Outstanding and affected, to execute supplemental indentures for the

                                     A2-7
<PAGE>

purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of the Indenture or of modifying in any manner the rights of
the Holders of such Series of Securities; provided that the Company, the
Guarantor and the Trustee may not, without the consent of the Holder of each
Subordinated Notes then Outstanding and affected thereby:  (a) change the time
of payment of the principal (or any installment) of any Subordinated Note, or
reduce the principal amount thereof, or reduce the rate or change the time of
payment of interest thereon, or impair the right to institute suit for the
enforcement of any payment on any Subordinated Note when due or (b) reduce the
percentage in principal amount of the Subordinated Notes.  The Indenture also
contains provisions providing that prior to the acceleration of the maturity of
any Subordinated Note, the Holders of a majority in aggregate principal amount
of Subordinated Notes may, on behalf of the Holders of all Subordinated Notes
waive any past default with respect to the Subordinated Notes and its
consequences, except a default (i) in respect of a covenant or provision of the
Indenture or of any Subordinated Note which cannot be modified or amended
without the consent of the Holder of each Outstanding Subordinated Note or (ii)
in the payment of the principal of, any premium or interest (including any
Additional Interest) on, or any Additional Amounts with respect to the
Subordinated Notes.

     No reference herein to the Indenture and no provision of this Subordinated
Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and premium, if
any, and interest on this Subordinated Note at the time and place and at the
rate and in the money herein prescribed.

     The Company shall have the right at any time during the term of this
Subordinated Note, from time to time, to extend the interest payment period of
such Subordinated Note (each such deferral period an "Extension Period"), during
which periods the Company shall have the right not to make payments of interest
on any interest payment date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest, if any,
thereon to the extent permitted by applicable law) to the Person in whose name
such Subordinated Note or any predecessor Subordinated Note is registered on the
books and records of the Company at the close of business on the Regular Record
Date.  Prior to the termination of any such Extension Period, the Company may
further extend the interest payment period, provided that no Extension Period
shall extend beyond the Mandatory Redemption Date, if the Trust Securities are
at the time outstanding, or the Maturity Date of this Subordinated Note.  Upon
the termination of any such Extension Period and upon the payment of all accrued

                                     A2-8
<PAGE>

and unpaid interest and any Additional Interest then due, the Company may elect
to being a new Extension Period.

     As provided in the Indenture and subject to certain limitations herein and
therein set forth, this Subordinated Note is transferable by the registered
Holder hereof on the Securities Register of the Company, upon surrender of this
Subordinated Note for registration of transfer at the office or agency of the
Trustee in the City and State of New York accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company or the Trustee duly
executed by the registered Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Subordinated Notes of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

     Prior to due presentment for registration of transfer of this Subordinated
Note, the Company, the Guarantor, the Trustee, any paying agent and the
Securities Registrar may deem and treat the registered holder hereof as the
absolute owner hereof (whether or not this Subordinated Note shall be overdue
and notwithstanding any notice of ownership or writing hereon made by anyone
other than the Securities Registrar) for the purpose of receiving payment of or
on account of the principal hereof and premium, if any, and interest due hereon
and for all other purposes, and neither the Company nor the Guarantor nor the
Trustee nor any paying agent nor any Securities Registrar shall be affected by
any notice to the contrary.

     No recourse shall be had for the payment of the principal of or the
interest on this Subordinated Note, or for any claim based hereon, or otherwise
in respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

     The Subordinated Notes of this series are issuable only in registered form
without coupons in denominations of $100,000 and any integral multiple of $1,000
thereof. A holder of Subordinated Notes may transfer or exchange Subordinated
Notes held by it only in minimum denominations of $100,000 and integral
multiples of $1,000 in excess thereof, and only if such transfer or exchange
does not result in such holder's holding Subordinated Notes in a

                                     A2-9
<PAGE>

denomination of less than $100,000. Any attempted transfer, sale or other
disposition of Subordinated Notes in a denomination of less than $100,000 shall
be deemed to be void and of no legal effect whatsoever.

     All terms used in this Subordinated Note that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

     THE INDENTURE AND THE SUBORDINATED NOTES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS
PRINCIPLES OF CONFLICTS OF LAWS.
