     Section 1.03.  Remarketing Provisions.  (a) Sections 8.02(a) and (b) of the

               Section 8.04, upon and at any time after the occurrence of a
               Trigger Event or a Cross Default and if the Senior Notes have
               been distributed to the holders of the Trust Securities, the
               holders of a majority in principal amount of the Senior Notes
               (the "Requesting Holders") will have the right to require
               remarketing of the Senior Notes. The Requesting Holders may
               exercise this right by delivering a written notice to the
               Remarketing Agent by 10:00 a.m. on any date on or after the date
               on which such Trigger Event or Cross Default occurs. Upon the
               receipt of such notice, the Remarketing Agent shall immediately
               deliver a written notice to the Company on behalf of the
               Requesting Holders (the "Remarketing Notice"). If the Requesting
               Holders exercise their right to require the remarketing of the
               Senior Notes, the Reset Date shall be the date on which such
               Remarketing Notice is delivered.

                         (ii) If the Requesting Holders do not exercise their
                    right to require the remarketing of the Senior Notes
                    pursuant to Section 8.02(a)(i) above with respect to any
                    Trigger Event or Cross Default, the Requesting Holders shall
                    have the right to require the remarketing of the Senior
                    Notes in accordance with Section 8.02(a)(i) at any
                    subsequent time with respect to the same Trigger Event or
                    Cross Default or with respect to any subsequent Trigger
                    Event or Cross Default.

                    (b)  If the Company and the Guarantor have complied in all
               material respects with all covenants set forth in the Remarketing
               Agreement, as amended, then by 3:00 p.m., New York City time,

                                       4
<PAGE>

               on the Reset Date, the Remarketing Agent shall request Bids from
               the Reference Corporate Dealers. The Remarketing Agent shall
               disclose to Company the Bids obtained and determine the lowest
               Bid Rate (the "Winning Bid Rate") from among the Bids obtained on
               the Reset Date. By 4:30 p.m., New York City time, on the Reset
               Date, the Remarketing Agent shall notify the Company 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, or if
               the Company and the Guarantor have not complied in all material
               respects with all covenants set forth in the Remarketing
               Agreement, as amended, the Remarketing shall be deemed to be a
               Failed Remarketing on such date; provided, that the Company's
               obligation to furnish the Offering Memorandum to the Remarketing
               Agent by 11:00 a.m. (New York City time) on the Reset Date
               pursuant to Section 13 of the Remarketing Agreement shall not be
               subject to the foregoing qualification as to materiality. The
               Winning Bid Rate determined by the Remarketing Agent, absent
               manifest error, shall be binding and conclusive upon the holders
               of the Trust Senior Notes, the Company, the Guarantor and the
               Trust.

     Section 1.04.  Successful Remarketing.  Section 8.02(d) of the First
Supplemental Indenture shall be supplemented by the following:

               On the Remarketing Settlement Date following the settlement of
               the purchase and sale of the Senior Notes, the provisions of this
               Section 8.02 (other than Sections 8.02(i) and 8.02(j)) shall
               terminate and shall be of no further effect.

     Section 1.05.  Failed Remarketing. (a) Section 8.05 of the First
Supplemental Indenture is hereby superseded in its entirety by the following:

                    SECTION 8.05. Failed Remarketing. The Remarketing Agent
               shall give notice of any Failed Remarketing on or after the date
               such Failed Remarketing occurs to the Company, the Trustee and
               the Paying Agent.

     Section 1.06.  Interest Rate. Each reference to "150 basis points" in the
First Supplemental Indenture and in each of the Exhibits thereto is hereby
superseded by a reference to "566 basis points". Such amended Interest Rate
shall be effective on and as of April 1, 2001. Upon surrender of any
certificates representing Senior Notes, replacement certificates representing
such Senior Notes

                                       5
<PAGE>

and reflecting this Amendment shall be executed by the Company, with the
Guarantee endorsed thereon executed by the Guarantor, and delivered to the
Trustee for authentication, and the Trustee shall thereupon authenticate and
deliver such Senior Notes to the holders of the Senior Notes in accordance with
the Base Indenture.

this Second Supplemental Indenture.

     Section 2.02.  Limitation on Liens. If any Mutual Party creates, assumes,
incurs, or otherwise permits to exist any Lien on any property now owned or

proceeds into a collateral account for the payment of interest on the XL
Securities pursuant to the section entitled "Use of Proceeds" of Annex A to
Amendment No. 1), the Company and the Guarantor will immediately notify the
Remarketing Agent and the Trustee thereof and will cause such Mutual Party to
secure any obligations of any Mutual Party under the Senior Notes and any
guarantee thereof by such Mutual Party equally and ratably with such XL
Securities or such guarantee thereof.

     Section 2.03.  Limitation on Senior Debt. No Mutual Party will create,
incur, assume or permit to exist any Debt, other than the XL Securities or any
guarantee thereof, not outstanding on the date hereof that ranks pari passu with
or senior to the Senior Notes in right of payment. For purposes hereof, "Debt"

duplication: (a) all liabilities, obligations and indebtedness for borrowed
money, including but not limited to obligations evidenced by bonds, debentures,
notes or other similar instruments of any such Person, (b) all obligations to
pay the deferred purchase price of property or services of any such Person

                                       6
<PAGE>

from such Person and arising in the ordinary course of business for not more
than 90 days not subject to (a) above), (c) all obligations of such Person under
a lease that are required to be capitalized and accounted for as capital lease
obligations under GAAP, (d) all Debt of any other Person secured by a Lien on
any asset of any such Person, (e) all obligations, contingent or otherwise, of
any such Person relating to the face amount of letters of credit, whether or not
drawn, and banker's acceptances issued for the account of any such Person, but
excluding any obligation relating to an undrawn letter of credit if the undrawn
letter of credit is issued in connection with a liability for which a reserve
has been established by such Person in accordance with GAAP, (f) all obligations
incurred by any such Person pursuant to any interest rate protection agreements
and/or other types of hedging agreements which are due and payable and (g) all
contingent obligations of any such Person with respect to Debt referred to in
clauses (a) through (f) of this definition. For purposes hereof, "GAAP" shall

Indenture, are in all respects ratified and confirmed, and this Second
Supplemental Indenture shall be deemed part of the Base Indenture and the First
Supplemental Indenture in the manner and to the extent herein and therein
provided. The provisions of this Second Supplemental Indenture shall supersede
the provisions of the Base Indenture and the First Supplemental Indenture to the
extent the Base Indenture or the First Supplemental Indenture is inconsistent
herewith.

shall be governed by such laws, without reference to the choice of laws rules

     Section 3.04.  Severability. If any provision in this Second Supplemental

financial statements and related schedules and notes of the U.S. Insurance
Subsidiaries for the years ended December 31, 1999 and 2000 (the "Audited
Statutory Financial Statements") fairly present the financial condition, results
of operations, cash flows and changes in capital and surplus of the U.S.

                  (b) The unaudited statutory financial statements and related
schedules and notes of the U.S. Insurance Subsidiaries for periods commencing
subsequent to December 31, 2000 (the "Unaudited Statutory Financial Statements",

                                      -21-

Transactions and the Restructuring and contain all material assumptions relating
to such projections and data. The Company believes such projections and the
assumptions upon which they are based are reasonable.

                  SECTION 3.16. Compliance with ERISA. Each member of the ERISA
                                ---------------------
Group has fulfilled its obligations under the minimum funding standards of ERISA
and the Internal Revenue Code with respect to each Plan and is in compliance, in
all material respects, with the presently applicable provisions of ERISA and the
Internal Revenue Code with respect to each Plan. No member of the ERISA Group
has (i) sought a waiver of the minimum funding standard under Section 412 of the
Internal Revenue Code in respect of any Plan, (ii) failed to make any
contribution or payment to any Plan or Multiemployer Plan or in respect of any
Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement,
which has resulted or could result in the imposition of a Lien or the posting of
a bond or other security under ERISA or the Internal Revenue Code or (iii)
incurred any liability under Title IV of ERISA other than a liability to the
PBGC for premiums under Section 4007 of ERISA.

any of its Subsidiaries have any material liabilities (including tax
liabilities), absolute or contingent, that are required to be reserved against
in a financial statement prepared in accordance with GAAP or Statutory
Accounting Principles that are not so adequately reserved against. Neither the
Company nor any of its Subsidiaries has any material reinsurance receivable that
is required to be reserved against in accordance with GAAP or Statutory
Accounting Principles other than those provided for in the reserve against
reinsurance recoverables reflected in the Financial Statements and the
consolidated financial statements of the Company and its Subsidiaries prepared
in accordance with GAAP. At December 31, 2000, neither the Company nor any of
its Subsidiaries had any material liabilities (absolute or contingent) other
than those reflected in the Financial Statements and the consolidated financial
statements prepared in accordance with GAAP. Since December 31, 2000, the
Company and its Subsidiaries have not incurred any material liabilities
(absolute or contingent) other than with respect to claims under insurance
policies written by the Insurance Subsidiaries and reported in the ordinary
course of business. The frequency and severity of such claims within the
individual lines of business of the Company and its Subsidiaries since December
31, 2000, are consistent with those reported for comparable periods prior to
December 31, 2000.

                  SECTION 3.18. No Material Change. Since December 31, 2000,

practice or policy) by the Company or any of its Subsidiaries; (h) there has not

Subsidiaries, any (i) employment, deferred compensation, severance, retirement

(or any amendment to any such existing agreement) outside of the ordinary course
of business, (ii) grant of any severance or termination pay to any director,
officer or employee outside of the ordinary course of business, (iii) change in

expenses in the ordinary course of business and advances of salary (not
exceeding one month's pay); (i) there has been no material damage, theft or
casualty loss by the Company or any of its Subsidiaries; (j) there has not been
any change by the Company or any of its Subsidiaries in underwriting practices

course of business, or (iii) any entering into or any commutation of any
reinsurance treaty by the Company or any of its Subsidiaries outside of the
ordinary course of business; (l) there has not been any insurance transaction by
the Company or any of its Subsidiaries other than in the ordinary course of

circumstance causing a Material Adverse Effect, nor any development that would,
singly or in the aggregate, result in a Material Adverse Effect.

                  SECTION 3.19. Insurance Matters. (a) The Company and its
                                -----------------
Subsidiaries are each in compliance in all material respects with the
requirements of all Insurance Acts and have filed all material reports,
documents or other information required to be filed thereunder; and neither the
Company nor any of its Subsidiaries has received any notification from any
insurance regulatory authority, commission or other insurance regulatory body in
the United States or elsewhere to the effect that the Company or any of its
Subsidiaries is not in compliance in any material respect with the Insurance
Acts.

                  (b) Neither the Company nor any of its Subsidiaries has made
any change in its insurance reserving practices, either on a gross or net of
reinsurance basis, since Decem-
<PAGE>

                                      -23-

ber 31, 2000, that would, singly or in the aggregate, have (i) a Material
Adverse Effect or (ii) a material adverse effect on the ability of any of the
Insurance Subsidiaries to pay dividends or the amount thereof.

                  (c) All insurance policies issued by the Company and each
Insurance Subsidiary, as now in force, are, to the extent required under
applicable law, in a form acceptable to applicable regulatory authorities or
have been filed and not objected to by such authorities within the period
provided for objection other than any failure to be in such form or to have been
so filed as would not, singly or in the aggregate, have a Material Adverse
Effect. All premium rates, rating plans and policy forms established or used by
the Company or any Insurance Subsidiary that are required to be filed with or
approved by insurance regulatory authorities have been so filed or approved, the
premiums charged conform in all respects to the premiums so filed or approved
and comply in all respects with the insurance laws applicable thereto and no
such premiums are subject to any review or investigation by any insurance
regulatory authority other than any failure to be so filed or approved or to so
comply or any review or investigation as would not, singly or in the aggregate,
have a Material Adverse Effect.

                  (d) Except as specifically set forth on Schedule 3.19(d), no
loss experience has developed, within any individual lines of business or on an
aggregate basis for all lines, that would require or make it appropriate for the
Company or any of its Subsidiaries to alter or modify its reserving methodology
or assumptions since December 31, 2000.

                  (e) All material reinsurance treaties, contracts, agreements
and arrangements ("Reinsurance Arrangements") to which the Company or any of its
Subsidiaries is a party are in full force and effect and are valid and binding
in accordance with their terms on the insurance company party thereto. The
Company believes that, except as disclosed in its periodic reports filed with
the U.S. Securities and Exchange Commission under the Exchange Act prior to the
date hereof or as disclosed on Schedule 3.19(e), all amounts recoverable by the
Company or any of its Subsidiaries pursuant to any Reinsurance Arrangement are
fully collectible in due course. Except as disclosed in its periodic reports
filed with the U.S. Securities and Exchange Commission under the Exchange Act
prior to the date hereof, neither the Company nor any of its Subsidiaries nor
any other party thereto is in default as to any Reinsurance Arrangement and
there is no reason to believe that the financial condition of any such other
party is impaired to the extent that a default thereunder may reasonably be
anticipated. None of the Reinsurance Arrangements contains any provision that
may permit the other party thereto to terminate such Reinsurance Arrangement by
reason of the transactions contemplated by the Transaction Documents.

have been made with state insurance regulatory authorities by the Company and
its Subsidiaries have been duly and timely made, and when filed were in
compliance in all material respects with the requirements of each such Insurance
Act.

                  (h) No Insurance Department has taken, or stated (orally or in
writing) that it intends to take or that it may take, any action to seize
control of the Company or any of its Subsidiaries through rehabilitation,
liquidation or otherwise, and has not otherwise precluded, or stated (orally or
in writing) that it intends to preclude or may preclude, the Insurance
Subsidiaries from writing.

                  SECTION 3.20. Full Disclosure. The information heretofore

operations, condition (financial or otherwise), prospects or Permits of the
Company and its Subsidiaries or the ability of the Company and its Subsidiaries
to perform their respective obligations under the Transaction Documents to which
they are party.

                  SECTION 3.21. Solicitation. No form of general solicitation or
                                ------------
general advertising was used by the Company or any of its Subsidiaries or any
other Person acting on their behalf in respect of the Securities or in
connection with the offer and sale of the Securities. None of the Company or any
of its Subsidiaries and no Person acting on any of their behalf has, either
directly or indirectly, sold or offered for sale to any Person any of the
Securities or, within the six months prior to the date hereof, any other similar
security of the Company or any of its Subsidiaries, and none of the Company or
any of its Subsidiaries and no Person authorized to act on any of their behalf
(except that neither the Company nor any of its Subsidiaries make any
representation as to the Purchasers and their Affiliates) will sell or offer for
sale any such security to, or solicit any offers to buy any such security from,
or otherwise approach or negotiate in respect thereof with, any Person or
Persons so as thereby to cause the issuance or sale of any of the Securities to
be in violation of any of the provisions of Section 5 of the Securities Act.
Assuming the accuracy of the representations and warranties of the Purchasers in
Sections 4.2 and 4.3, it is not necessary in connection with the issuance and
sale of

Holding Company Act of 1935, as amended, the Federal Power Act, the Interstate
Commerce Act or to any federal or state statute or regulation limiting its
ability to issue and perform its obligations under any Transaction Document.

                  (b) Neither the Company nor any of its Subsidiaries is, or
will be after giving effect to the transactions contemplated by the Transaction
Documents, an "investment company" within the meaning of the Investment Company
Act of 1940, as amended.

                  (c) Neither the Company nor any of its Subsidiaries has taken
or will take any action that would cause this Agreement, the issuance and sale
of the Securities or the use of the proceeds therefrom to violate the provisions
of Regulation T, U or X of the Board of Governors of the Federal Reserve System.

                  SECTION 3.23. Reservation of Shares. Prior to the Closing

that selected the Designee whose vacancy is to be filled according to the
procedures described above. Any such director shall comply with all applicable
statutory requirements of the Insurance Departments.

for employment or hire any Person who, at the time of such solicitation or
hiring, is employed by Newco or any of its Subsidiaries or induce or encourage
any such Person to leave the employ of Newco or any of its Subsidiaries or to
become employed by any Person other than Newco or any of its Subsidiaries.

                  SECTION 6.7. Certain Transactions. The Company shall not, and
                               --------------------

specialty insurance operations as successor to its Program Business as promptly
as practicable.

Amendments. (a) No failure or delay on the part of any party in exercising any
----------
right, power or remedy hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right, power or remedy preclude any
other or further exercise thereof or the exercise of any other right, power or
remedy.

                  (b) No right or remedy herein conferred upon or reserved to
the Purchasers or the Holders from time to time of Securities is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, 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 prevent the concurrent assertion or employment of any other
appropriate right or remedy. Every power and remedy given by any Transaction
Document or by law may
<PAGE>

                                      -41-

be exercised from time to time, and as often as shall be deemed expedient, by
the Obligors, the Purchasers or the Holders from time to time of Securities.

               (c) Any provision of this Agreement may be amended, supplemented
or waived if, but only if such amendment, supplement or waiver is in writing and
is signed by the Company and the Purchasers, if such proposed amendment,
supplement or waiver is effective on or prior to the Closing Date, and the
Requisite Holders, if such proposed amendment, supplement or waiver is effective
after the Closing Date. In determining whether the Requisite Holders have
concurred in any direction, consent, or waiver as provided in any Transaction
Document, Debentures which are owned by the Company or any of its Affiliates
shall be disregarded and deemed not to be outstanding for the purpose of any
such determination; provided, however, that any amendment, supplement or waiver
                    --------  -------
which adversely affects the rights of any Holder hereunder shall require such
Holder's consent unless the amendment, supplement or waiver adversely affects
the rights of all Holders in the same manner.

               SECTION 7.3. Indemnification. The Obligors, jointly and
                            ---------------
severally, agree to indemnify and hold harmless the Purchasers and each Holder,
their respective Affiliates, directors, officers and employees and each Person,
if any, who controls any Purchaser and each Holder, or any of their Affiliates,
within the meaning of the Securities Act or the Exchange Act (a "Controlling
Person"), and the respective partners, agents, employees, officers and directors
of the Purchasers and each Holder, their respective Affiliates and any such
Controlling Person (each, an "Indemnified Party" and, collectively, the
"Indemnified Parties"), from and against any and all losses, claims, damages,
liabilities and expenses (including, as incurred, reasonable costs of
investigating, preparing or defending any such claim or action, whether or not
such Indemnified Party is a party thereto), that arise out of, or are in
connection with (i) any breach of representation or warranty (including any
misrepresentation in, or omission from, any certificate or other document
furnished or to be furnished by it to any Purchaser and/or the Holders
hereunder) or nonfulfillment of any covenant or agreement on the part of the
Obligors under any Transaction Document (without giving effect to any
qualifications of any representation or warranty with respect to knowledge) or
(ii) any pending or threatened claims, actions, suits, proceedings, demands,
assessments, judgments, costs and expenses incident to any of the foregoing or
to the Transaction Documents or the Transactions; provided, however, that the
Obligors will not be responsible for any losses, claims, damages, liabilities or
expenses that are determined by final judgment of a court of competent
jurisdiction to result solely from such Indemnified Party's gross negligence or
willful misconduct. The Obligors and the Purchasers also agree that no
Indemnified Party shall have any liability (except for breach of provisions of
this Agreement) for losses, claims, damages, liabilities or expenses, including
legal fees, incurred by the Obligors in connection with this Agreement unless
they are determined by final judgment of a court of competent jurisdiction to
result from such Indemnified Party's gross negligence or willful misconduct.
<PAGE>

                                      -42-

               In case any action shall be brought against an Indemnified Party
with respect to which indemnity may be sought against the Obligors under this
Agreement, such Indemnified Party shall promptly notify the Obligors in writing
and the Obligors shall, if requested by such Indemnified Party or if the
Obligors desire to do so, assume the defense thereof, including the employment
of counsel reasonably satisfactory to such Indemnified Party and payment of all
reasonable fees and expenses. The failure to so notify the Obligors shall not
affect any obligations the Obligors may have to such Indemnified Party under
this Agreement or otherwise unless the Obligors are materially adversely
affected by such failure. Such Indemnified Party shall have the right to employ
separate counsel in such action and participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Indemnified
Party, unless: (i) the Obligors have failed to assume the defense and employ
counsel reasonably satisfactory to such Indemnified Party or (ii) the named
parties to any such action (including any impleaded parties) include such
Indemnified Party, and one or more of the Obligors, and such Indemnified Party
shall have been advised by counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to
such Obligor, in which case, if such Indemnified Party notifies the Obligors in
writing that it elects to employ separate counsel at the expense of the
Obligors, the Obligors shall not have the right to assume the defense of such
action or proceeding on behalf of such Indemnified Party; provided, however,
that the Obligors shall not, in connection with any one such action or
proceeding or separate but substantially similar or related actions or
proceedings in the same jurisdiction arising out of the same general allegations
or circumstances, be responsible hereunder for the reasonable fees and expenses
of more than one such firm of separate counsel, in addition to any local
counsel, which counsel shall be designated by XL if XL is at such time an
Indemnified Party with respect to such matter and otherwise by such Indemnified
Party. The Obligors shall not be liable for any settlement of any such action
effected without the written consent of the Obligors (which shall not be
unreasonably withheld or delayed) and the Obligors agree to indemnify and hold
harmless each Indemnified Party from and against any loss or liability by reason
of settlement of any action effected with the consent of the Obligors. In
addition, the Obligors will not, without the prior written consent of XL, if XL
is at such time and Indemnified Party with respect to such matter and otherwise
by such Indemnified Party, settle or compromise or consent to the entry of any
judgment in or otherwise seek to terminate any pending or threatened action,
claim, suit or proceeding in respect to which indemnification or contribution
may be sought hereunder (whether or not any Indemnified Party is a party
thereto) unless such settlement, compromise, consent or termination includes an
express, unconditional release of the Purchasers and the other Indemnified
Parties, satisfactory in form and substance to the Purchasers, from all
liability arising out of such action, claim, suit or proceeding.

               The indemnification and expense reimbursement obligations set
forth in this Section 7.3 (i) shall be in addition to any liability the Obligors
may have to any Indemnified Party at common law or otherwise, (ii) shall survive
the termination of this Agreement and the
<PAGE>

                                      -43-

other Transaction Documents and the payment, conversion and/or exchange in full
of the Debentures and (iii) shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of the Purchasers or any

-----------------------------
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK. ANY
DISPUTE UNDER THIS AGREEMENT THAT IS NOT SETTLED BY MUTUAL CONSENT SHALL BE
FINALLY ADJUDICATED BY ANY FEDERAL OR STATE COURT SITTING IN THE CITY, COUNTY
AND STATE OF NEW YORK, AND THE COMPANY CONSENTS TO THE EXCLUSIVE JURISDICTION OF
SUCH COURTS (OR ANY APPELLATE COURT THEREFROM) OVER ANY SUCH DISPUTE. THE
COMPANY HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE FEDERAL
AND NEW YORK STATE COURTS LOCATED IN NEW YORK COUNTY IN CONNECTION WITH ANY
SUIT, ACTION OR PROCEEDING RELATED TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS
CONTEMPLATED HEREBY, IRREVOCABLY WAIVES ANY DEFENSE OF LACK OF PERSONAL
JURISDICTION AND IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUIT,
ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT. THE COMPANY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER
APPLICABLE LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING
OF VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT AND
ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS
BEEN BROUGHT IN AN INCONVENIENT FORUM.

               (b) By the execution and delivery of this Agreement, the Company
and each of the Guarantors (i) acknowledges that it will, by separate written
instrument, designate and appoint The CT Corporation System, Inc., 111 Eighth
Avenue, New York, New York 10011 (and any successor entity) as its authorized
agent upon which process may be served in any suit or proceeding arising out of

suit or proceeding and (iv) agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law.

               (c) All payments made or required to be made hereunder shall
be made in U.S. dollars. The Obligors agree to indemnify the Holder against any
loss incurred by such party as a result of any judgment or order being given or
made against the Obligors, for any U.S. dollar amount due under this Agreement
and such judgment or order being expressed and paid in a currency (the "Judgment
Currency") other than United States dollars and as a result of any
<PAGE>

                                      -45-

variation as between (i) the rate of exchange at which the United States dollar
amount is converted into the Judgment Currency for the purpose of such judgment
or order and (ii) the spot rate of exchange in The City of New York at which
such party on the date of payment of such judgment or order is able to purchase
United States dollars with the amount of the Judgment Currency actually received
by such party if such party had utilized such amount of Judgment Currency to
purchase United States dollars as promptly as practicable upon such party's
receipt thereof. The foregoing indemnity shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term "spot rate of
exchange" shall include any premiums and costs of exchange payable in connection
with the purchase of, or conversion into, United States dollars.

               All amounts paid by the Company or any Guarantor hereunder shall
be paid free and clear of, and without any deduction or withholding for or on
account of, any present or future taxes, duties, assessments or other
governmental charges of whatever nature imposed or levied by or on behalf of
Bermuda or any political subdivision thereof or by any authority therein or
thereto or within any other jurisdiction in which the Company or any of its
Subsidiaries is organized or engaged in business for tax purposes having power
to tax, unless such deduction or withholding is required by applicable law, in
which event, each of the other parties hereto agrees to pay additional amounts
so that the persons entitled to such payments will receive the amount that such
persons would otherwise have received but for such deduction or withholding.

                            --------
representations and warranties in any Transaction Document and in the
certificates or other instruments prepared or delivered in connection with or
pursuant to any Transaction Document shall be considered to have been relied

regardless of any investigation made by or on behalf of the Purchasers, and
shall continue in full force and effect in accordance with their terms.

               (b) All indemnities set forth herein, including in Section
7.3, shall survive the execution and delivery of this Agreement, the issuance
and purchase of the Securities and the repayment and cancellation of the
Debentures.

number of counterparts each of which shall be an original with the same effect

under or by reason of the Transaction Documents.

this Agreement pursuant to which Newco shall, by so executing this Agreement,

3.19, 3.20, 3.22 and 3.23 of this Agreement to the holders as if all references
