conditions and relying upon the representations and warranties herein set forth,

Credit for the account of an Account Party at any time or from time to time on
or after the Effective Date and to but not including the Expiration Date (it
being understood that Syndicated Letters of Credit may be outstanding for the
account of one or more of the Account Parties at any time). The Banks shall have
no obligation to issue any Syndicated Letters of Credit if, after such
Syndicated Letters of Credit are issued, the Letter of Credit Exposure upon such
issuance would exceed the lesser of (x) the aggregate of the Banks' Letter of
Credit Committed Amounts and (y) the Pledged Securities Available Amount. Each
Bank's "Letter of Credit Committed Amount" at any time shall be equal to the
amount set forth as its "Initial Letter of Credit Committed Amount" below its
name on the signature pages hereof, as such amount may have been reduced under
Section 2.12 hereof at such time, and subject to transfer to or from another
Bank as provided in Section 9.13 hereof.

        (b) TERMS OF SYNDICATED LETTERS OF CREDIT. The Account Parties shall not
request to be issued, and the Banks shall have no obligation to issue, any
Syndicated Letter of Credit except within the following limitations: (i) each
Syndicated Letter of Credit shall have an expiration date no later than 12
months after the date of issuance thereof; PROVIDED, HOWEVER, that any
Syndicated Letter of Credit may have an "evergreen" provision having
substantially the effect set forth on Schedule 2.01(b) hereof, (ii) each
Syndicated Letter of Credit shall be denominated in Dollars and (iii) each
Syndicated Letter of Credit shall be payable only against sight drafts (and not
time drafts).

        (c) FORM OF SYNDICATED LETTERS OF CREDIT. The Banks shall have no
obligation to issue any letter of credit which is unsatisfactory in form,
substance or beneficiary to the Agent in the exercise of its reasonable judgment
consistent with its customary practice; PROVIDED that, without the prior consent
of each Bank, no Syndicated Letter of Credit may be issued that would vary the
several and not joint nature of the obligations of the Banks thereunder as
provided in the next succeeding sentence. Each Syndicated Letter of Credit shall
be issued by all of the Banks, acting through the Agent, at the time of issuance
as a single multi-bank letter of credit, but the obligation of each Bank
thereunder shall be several and not joint, based upon its Letter of Credit
Commitment Percentage. It is contemplated that one or more Letters of Credit
which are requested to be issued by, and which are issued for the account of, XL
Capital, XL Insurance or XL Re, respectively, may be stated to be issued for the
account of XL Reinsurance America Inc., ECS, Inc., or XL Re Latin America Ltd,
in which XL Capital, XL Insurance or XL Re, as the case may be, has a direct or
indirect ownership interest, provided that, notwithstanding the fact that the
name of XL Capital, XL Insurance or XL Re, as the case may be, may not appear on
the face of any such Letter of Credit, XL Capital, XL Insurance or XL Re, as the
case may be, shall be the Account Party with respect to such Letter of Credit
and shall have all Letter of Credit Reimbursement Obligations and other
obligations hereunder with respect thereto.

                (ii) delivering to the Agent a completed application, in the
        form annexed hereto as EXHIBIT D, or in such other form as is from time
        to time be required by the Agent in accordance with its customary
        practice with respect to its customers generally (a "Letter of Credit
        Application"), together with such other certificates, documents and
        other papers as are specified in such application.

Upon receiving any such notice, the Agent shall notify the Banks of such
proposed Syndicated Letter of Credit (which notice shall specify the Stated
Amount and term of such proposed Syndicated Letter of Credit), and shall
determine, as of the close of business on the Business Day before such proposed
issuance, whether such proposed Letter of Credit complies with the limitations
set forth in Section 2.01 hereof. If such limitations set forth in Section 2.01
are not satisfied or if the Required Banks have given notice to the Agent to
cease executing and delivering Syndicated Letters of Credit pursuant to Section
2.02(d)(i) hereof, the Agent shall not be authorized to execute and deliver such
Syndicated Letter of Credit. If the Agent executes and delivers a Syndicated
Letter of Credit, it shall deliver the original of such Syndicated Letter of
Credit to the beneficiary thereof or as the Account Party shall otherwise
direct.

        (b) ISSUANCE AND ADMINISTRATION. Each Syndicated Letter of Credit shall
be executed and delivered by the Agent in the name and on behalf of, and as
attorney-in-fact for, each Bank party to such Syndicated Letter of Credit, and
the Agent shall act under each Syndicated Letter of Credit, and each Syndicated
Letter of Credit shall expressly provide that the Agent shall act, as the agent
of each Bank to (a) receive drafts, other demands for payment and other
documents presented by the beneficiary under such Syndicated Letter of Credit,
(b) determine whether such drafts, demands and documents are in compliance with
the terms and conditions of such Syndicated Letter of Credit and (c) notify such
Bank and the Account Parties that a valid drawing has been made and the date
that the related LC Disbursement is to be made; PROVIDED that the Agent shall
have no obligation or liability for any LC Disbursement under such Syndicated
Letter of Credit, and each Syndicated Letter of Credit shall expressly so
provide. Each Bank hereby irrevocably appoints and designates the Agent as its
attorney-in-fact, acting through any duly authorized officer of the Agent, to
execute and deliver in the name and on behalf of such Bank each Syndicated
Letter of Credit to be issued by such Bank hereunder. Promptly upon the request
of the Agent, each Bank will furnish to the Agent such powers of attorney or
other evidence as any beneficiary of any Syndicated Letter of Credit may
reasonably request in order to demonstrate that the Agent has the power to act
as attorney-in-fact for such Bank to execute and deliver such Syndicated Letter
of Credit.

        (c) REQUEST FOR EXTENSION OR INCREASE. An Account Party may from time to
time request by providing a notice to the Agent the extension of the expiration
date of an outstanding Syndicated Letter of Credit or increase (or, with the
consent of the beneficiary, decrease) the Stated Amount of or the amount
available to be drawn on such Syndicated Letter of Credit. Such extension or
increase shall for all purposes hereunder be treated as though such Account
Party had requested issuance of a replacement Syndicated Letter of Credit
(except only that the Agent may, if it elects, execute and deliver a notice of
extension or increase (or, with the consent of the beneficiary, decrease) in
lieu of executing and delivering a new Syndicated Letter of Credit in
substitution for the outstanding Syndicated Letter of Credit).

        (d) LIMITATIONS ON ISSUANCE, EXTENSION AND AMENDMENT.

                                       15
<PAGE>

                (i) As between the Agent, on the one hand, and the Banks, on the
        other hand, the Agent shall not execute and deliver any Syndicated
        Letter of Credit if the Agent shall have received, at least two (2)
        Business Days before such execution and delivery, from the Required
        Banks an unrevoked written notice that any condition precedent set forth
        in Section 4.02 will not be satisfied as of the time of such execution
        and delivery and expressly requesting that the Agent cease to execute
        and deliver Syndicated Letters of Credit. Absent such notice, or unless
        the Agent determines that the applicable limitations set forth in
        Section 2.01 hereof are not satisfied, the Agent shall be justified and
        fully protected, as against the Banks, in executing and delivering such
        Syndicated Letter of Credit, notwithstanding any subsequent notices to
        the Agent, any knowledge of an Event of Default or Potential Default,
        any knowledge of failure of any condition specified in Section 4.02
        hereof to be satisfied, any other knowledge of the Agent, or any other
        event, condition or circumstance whatsoever.

                (ii) The Agent may amend, modify or supplement Syndicated
        Letters of Credit or Letter of Credit Applications, or waive compliance
        with any condition of issuance or payment, without the consent of, and
        without liability to, any Bank; PROVIDED that any such amendment,
        modification or supplement that extends the expiration date or increases
        the Stated Amount of or the amount available to be drawn on an
        outstanding Syndicated Letter of Credit shall be subject to Section
        2.01; and PROVIDED FURTHER that, without the prior consent of each Bank,
        no such amendment, modification or supplement of a Syndicated Letter of
        Credit may be made that would vary the several and not joint nature of
        the obligations of the Banks thereunder as provided in Section 2.01(c).

                (iii) If any Syndicated Letter of Credit shall provide for the
        automatic extension of the expiry date thereof, the Agent shall give
        notice that such expiry date shall not be extended if the Required Banks
        request the Agent provide such notice by giving notice to the Agent not
        more than 60 days, but not less than 45 days, prior to the current
        expiry date of such Syndicated Letter of Credit.

                (iv) No Syndicated Letter of Credit may be issued nor may the
        expiration date of any Syndicated Letter of Credit be extended at any
        time after the Conversion to Tranche System has been implemented.

                2.03. REIMBURSEMENT OF LC DISBURSEMENTS IN RESPECT OF SYNDICATED
LETTERS OF CREDIT, ETC.

        (a) REIMBURSEMENT. If any Bank shall make any LC Disbursement in respect
of any Syndicated Letter of Credit, regardless of the identity of the Account
Party of such Syndicated Letter of Credit, the Account Parties jointly and
severally agree that they shall reimburse such Bank in respect of such LC
Disbursement by paying to the Agent an amount equal to such LC Disbursement on
the date of such LC Disbursement (or, if later, the date which is one (1)
Business Day after notice of such LC Disbursement or of the drawing giving rise
to such LC Disbursement is given to XL Capital), without, protest or demand, all
of which are hereby waived, and an action therefor shall immediately accrue.

        (b) REIMBURSEMENT OBLIGATIONS ABSOLUTE. The Account Parties' joint and
several obligations to reimburse LC Disbursements as provided in paragraph (a)
of this Section shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement under any and
all circumstances whatsoever and irrespective of (i) any lack of validity or
enforceability of any Syndicated Letter of Credit, or any term or provision
therein, (ii) any draft or other document presented under a Syndicated Letter of
Credit proving to

                                       16
<PAGE>

be forged, fraudulent or invalid in any respect or any statement therein being
untrue or inaccurate in any respect, (iii) payment under a Syndicated Letter of
Credit against presentation of a draft or other document that does not comply
strictly with the terms of such Syndicated Letter of Credit, (iv) at any time or
from time to time, without notice to any Account Party, the time for any
performance of or compliance with any of such reimbursement obligations of any
other Account Party shall be waived, extended or renewed, (v) any of such
reimbursement obligations of any other Account Party shall be amended or
otherwise modified in any respect, or any guarantee of any of such reimbursement
obligations shall be released, substituted or exchanged in whole or in part or
otherwise dealt with, (vi) the occurrence of any Event of Default, (vii) the
existence of any proceedings of the type described in clause (g) or (h) of
Section 7.01 with respect to any other Account Party or any guarantor of any of
such reimbursement obligations, (viii) any lack of validity or enforceability of
any of such reimbursement obligations against any other Account Party or any
guarantor of any of such reimbursement obligations, or (ix) any other event or
circumstance whatsoever, whether or not similar to any of the foregoing, that
might, but for the provisions of this Section, constitute a legal or equitable
discharge of the obligations of any Account Party hereunder.

        Neither the Agent, nor any Bank nor any of their Related Parties shall
have any liability or responsibility by reason of or in connection with the
issuance or transfer of any Syndicated Letter of Credit or any payment or
failure to make any payment thereunder (irrespective of any of the circumstances
referred to in the preceding sentence), or any error, omission, interruption,
loss or delay in transmission or delivery of any draft, notice or other
communication under or relating to any Syndicated Letter of Credit (including
any document required to make a drawing thereunder), any error in interpretation
of technical terms or any consequence arising from causes beyond their control;
provided that the foregoing shall not be construed to excuse the Agent or a Bank
from liability to any Account Party to the extent of any direct damages (as
opposed to consequential damages, claims in respect of which are hereby waived
by the Account Parties to the extent permitted by applicable law) suffered by
any Account Party that are caused by the gross negligence or willful misconduct
of the Agent or a Bank. The parties hereto expressly agree that:

                (i) the Agent may accept documents that appear on their face to
        be in substantial compliance with the terms of a Syndicated Letter of
        Credit without responsibility for further investigation, regardless of
        any notice or information to the contrary, and may make payment upon
        presentation of documents that appear on their face to be in substantial
        compliance with the terms of such Syndicated Letter of Credit;

                (ii) the Agent shall have the right, in its sole discretion, to
        decline to accept such documents and to make such payment if such
        documents are not in strict compliance with the terms of such Syndicated
        Letter of Credit; and

                (iii) this sentence shall establish the standard of care to be
        exercised by the Agent when determining whether drafts and other
        documents presented under a Syndicated Letter of Credit comply with the
        terms thereof (and the parties hereto hereby waive, to the extent
        permitted by applicable law, any standard of care inconsistent with the
        foregoing).

        (c) DISBURSEMENT PROCEDURES. The Agent shall, within a reasonable time
following its receipt thereof, examine all documents purporting to represent a
demand for payment under any Syndicated Letter of Credit. The Agent shall
promptly after such examination (i) notify each of the Banks and the Account
Parties by telephone (confirmed by telecopy) of such demand for payment and (ii)
deliver to each Bank a copy of each document purporting to represent a demand
for payment under such Syndicated Letter of Credit. With respect to any drawing
properly made under a Syndicated Letter of Credit, each Bank will make an LC
Disbursement in respect of such Syndicated Letter of Credit in accordance with
its liability under such Syndicated Letter of Credit and this Agreement, such LC
Disbursement to be made to the account of the Agent most recently

                                       17
<PAGE>

designated by it for such purpose by notice to the Banks. The Agent will make
any such LC Disbursement available to the beneficiary of such Syndicated Letter
of Credit by promptly crediting the amounts so received, in like funds, to the
account identified by such beneficiary in connection with such demand for
payment. Promptly following any LC Disbursement by any Bank in respect of any
Syndicated Letter of Credit, the Agent will notify the Account Parties of such
LC Disbursement; provided that any failure to give or delay in giving such
notice shall not relieve the Account Parties of their obligation to reimburse
the Banks with respect to any such LC Disbursement.

        (d) INTERIM INTEREST. If any LC Disbursement with respect to a
Syndicated Letter of Credit is made, then, unless the Account Parties shall
reimburse such LC Disbursement in full on the date such LC Disbursement is made,
the unpaid amount thereof shall bear interest, for each day from and including
the date such LC Disbursement is made to but excluding the date that the Account
Parties reimburse such LC Disbursement, at the rate per annum equal to the
Applicable Interest Rate.

        2.04. PARTICIPATED LETTERS OF CREDIT.

        (a) GENERAL. Subject to the terms and conditions set forth herein, in
addition to the issuance of Syndicated Letters of Credit provided for in Section
2.01, any Account Party may request the Issuing Bank to issue Participated
Letters of Credit for the account of an Account Party at any time or from time
to time on or after the Effective Date and to but not including the Expiration
Date (it being understood that Participated Letters of Credit may be outstanding
for the account of one or more of the Account Parties at any time). The Issuing
Bank shall have no obligation to issue any Participated Letters of Credit if,
after such Participated Letters of Credit are issued, the Letter of Credit
Exposure upon such issuance would exceed the lesser of (x) the aggregate of the
Banks' Letter of Credit Committed Amounts and (y) the Pledged Securities
Available Amount.

        (b) TERMS OF PARTICIPATED LETTERS OF CREDIT. The Account Parties shall
not request to be issued, and the Issuing Bank shall have no obligation to
issue, any Participated Letter of Credit except within the following
limitations: (i) each Participated Letter of Credit shall have an expiration
date no later than 12 months after the date of issuance thereof; PROVIDED,
HOWEVER, that any Participated Letter of Credit may have an "evergreen"
provision having substantially the effect set forth on Schedule 2.01(b) hereof,
(ii) each Participated Letter of Credit shall be denominated in Dollars and
(iii) each Participated Letter of Credit shall be payable only against sight
drafts (and not time drafts).

        (c) FORM OF PARTICIPATED LETTERS OF CREDIT. The Issuing Bank shall have
no obligation to issue any letter of credit which is unsatisfactory in form,
substance or beneficiary to the Issuing Bank in the exercise of its reasonable
judgment consistent with its customary practice. It is contemplated that one or
more Letters of Credit which are requested to be issued by, and which are issued
for the account of, XL Capital, XL Insurance or XL Re, respectively, may be
stated to be issued for the account of XL Reinsurance America Inc., ECS, Inc.,
or XL Re Latin America Ltd, in which XL Capital, XL Insurance or XL Re, as the
case may be, has a direct or indirect ownership interest, provided that,
notwithstanding the fact that the name of XL Capital, XL Insurance or XL Re, as
the case may be, may not appear on the face of any such Letter of Credit, XL
Capital, XL Insurance or XL Re, as the case may be, shall be the Account Party
with respect to such Letter of Credit and shall have all Letter of Credit
Reimbursement Obligations and other obligations hereunder with respect thereto.

        2.05. PROCEDURE FOR ISSUANCE AND AMENDMENT OF PARTICIPATED LETTERS OF
CREDIT.

        (a) REQUEST FOR ISSUANCE. An Account Party may from time to time
request, upon at least three (3) Business Days' notice, the Issuing Bank to
issue a Participated Letter of Credit by:

                (i) delivering to the Issuing Bank and the Agent a written
        request to such effect, specifying the date on which such Participated
        Letter of Credit is to be issued, the expiration date thereof, and the
        Stated Amount thereof, and

                (ii) delivering to the Issuing Bank a completed Letter of Credit
        Application, together with such other certificates, documents and other
        papers as are specified in such application.

Upon receiving any such notice, the Issuing Bank shall promptly notify the Agent
(by telephone or otherwise), and furnish the Agent with the proposed form of
Participated Letter of Credit to be issued. The Agent shall, promptly upon
receiving such notice, notify the Banks of such proposed Participated Letter of
Credit (which notice shall specify the Stated Amount and term of such proposed
Participated Letter of Credit), and shall determine, as of the close of business
on the Business Day before such proposed issuance, whether such proposed
Participated Letter of Credit complies with the limitations set forth in Section
2.04 hereof. If such limitations set forth in Section 2.04 are not satisfied or
if the Required Banks have given notice to the Agent to cease issuing
Participated Letters of Credit pursuant to Section 2.05(c)(ii) hereof, the Agent
shall notify the Issuing Bank (in writing or by telephone promptly confirmed in
writing) that the Issuing Bank is not authorized to issue such Participated
Letter of Credit. If the Issuing Bank issues a Participated Letter of Credit, it
shall deliver the original of such Participated Letter of Credit to the
beneficiary thereof or as the Account Party shall otherwise direct, and shall
promptly notify the Agent thereof and furnish a copy thereof to the Agent.

        (b) REQUEST FOR EXTENSION OR INCREASE. An Account Party may from time to
time request the Issuing Bank to extend the expiration date of an outstanding
Participated Letter of Credit or increase (or, with the consent of the
beneficiary, decrease) the Stated Amount of or the amount available to be drawn
on such Participated Letter of Credit. Such extension or increase shall for all
purposes hereunder be treated as though such Account Party had requested
issuance of a replacement Participated Letter of Credit (except only that the
Issuing Bank may, if it elects, issue a notice of extension or increase (or,
with the consent of the beneficiary, decrease) in lieu of issuing a new
Participated Letter of Credit in substitution for the outstanding Participated
Letter of Credit).

        (c) LIMITATIONS ON ISSUANCE, EXTENSION AND AMENDMENT.

                (i) As between the Issuing Bank, on the one hand, and the Agent
        and the Banks, on the other hand, the Issuing Bank shall be justified
        and fully protected in issuing a Participated Letter of Credit after
        receiving authorization from the Agent as provided in Section 2.05(a)
        hereof, notwithstanding any subsequent notices to the Issuing Bank, any
        knowledge of an Event of Default (unless the Issuing Bank shall have
        received a notice specifying that such Event of Default is an "Event of
        Default" under this Agreement) or Potential Default, any knowledge of
        failure of any condition specified in Section 4.02 hereof to be
        satisfied, any other knowledge of the Issuing Bank, or any other event,
        condition or circumstance whatsoever. The Issuing Bank may amend, modify
        or supplement Participated Letters of Credit or Letter of Credit
        Applications, or waive compliance with any condition of issuance or
        payment, without the consent of, and without liability to, the Agent or
        any Bank, provided that any such amendment, modification or supplement
        that extends the expiration date or increases

                                       19
<PAGE>

        the Stated Amount of or the amount available to be drawn on an
        outstanding Participated Letter of Credit shall be subject to Section
        2.04.

                (ii) As between the Agent, on the one hand, and the Banks, on
        the other hand, the Agent shall not authorize issuance of any
        Participated Letter of Credit if the Agent shall have received, at least
        two (2) Business Days before authorizing such issuance, from the
        Required Banks an unrevoked written notice that any condition precedent
        set forth in Section 4.02 will not be satisfied as of the time of such
        issuance and expressly requesting that the Agent direct the Issuing Bank
        to cease to issue Participated Letters of Credit. Absent such notice, or
        unless the Agent determines that the applicable limitations set forth in
        Section 2.04 hereof are not satisfied, the Agent shall be justified and
        fully protected, as against the Banks, in authorizing the Issuing Bank
        to issue such Participated Letter of Credit, notwithstanding any
        subsequent notices to the Agent, any knowledge of an Event of Default or
        Potential Default, any knowledge of failure of any condition specified
        in Section 4.02 hereof to be satisfied, any other knowledge of the
        Agent, or any other event, condition or circumstance whatsoever.

                2.06. LETTER OF CREDIT PARTICIPATING INTERESTS.

        (a) GENERALLY. Concurrently with the issuance of each Participated
Letter of Credit, the Issuing Bank automatically shall be deemed, irrevocably
and unconditionally, to have sold, assigned, transferred and conveyed to each
other Bank, and each other Bank automatically shall be deemed, irrevocably and
unconditionally, severally to have purchased, acquired, accepted and assumed
from the Issuing Bank, without recourse to, or representation or warranty by,
the Issuing Bank, an undivided interest, in a proportion equal to such Bank's
Pro Rata share, in all of the Issuing Bank's rights and obligations in, to or
under such Participated Letter of Credit, the related Letter of Credit
Application, the related Letter of Credit Reimbursement Obligations, and all
collateral, guarantees and other rights from time to time directly or indirectly
securing the foregoing (such interest of each Bank being referred to herein as a
"Participated Letter of Credit Participating Interest", it being understood that
the Participated Letter of Credit Participating Interest of the Issuing Bank is
the interest not otherwise attributable to the Participated Letter of Credit
Participating Interests of the other Banks). Each Bank irrevocably and
unconditionally agrees to the immediately preceding sentence, such agreement
being herein referred to as such Bank's "Participated Letter of Credit
Participating Interest Commitment". Amounts other than Letter of Credit
Reimbursement Obligations and Letter of Credit Fees payable from time to time
under or in connection with a Participated Letter of Credit or related Letter of
Credit Application shall be for the sole account of the Issuing Bank. On the
date that any Purchasing Bank becomes a party to this Agreement in accordance
with Section 9.13(c) hereof, Participated Letter of Credit Participating
Interests in all outstanding Participated Letters of Credit held by the Bank
from which such Purchasing Bank acquired its interest hereunder shall be
proportionately reallocated between such Purchasing Bank and such transferor
Bank (and, to the extent such transferor Bank is the Issuing Bank, the
Purchasing Bank shall be deemed to have acquired a Participated Letter of Credit
Participating Interest from the Issuing Bank to such extent).

        (b) MAXIMUM AMOUNTS OF FUNDING OF PARTICIPATIONS.

                (i) This Section 2.06(b)(i) is applicable if the Conversion to
        Tranche System has not occurred. No Bank will be obligated to fund its
        Letter of Credit Commitment Percentage of a drawing on a Participated
        Letter of Credit if such funding would cause the aggregate amount of
        outstanding unreimbursed LC Disbursements by such Bank of drawings on
        Letters of Credit to exceed such Bank's Letter of Credit Committed
        Amount.

                                       20
<PAGE>

                (ii) This Section 2.06(b)(ii) is applicable if the Conversion to
        Tranche System has occurred. No Tranche 1 Bank, Tranche 2 Bank or
        Tranche X Bank, as the case may be, will be obligated to fund its Letter
        of Credit Commitment Percentage of a drawing on a Tranche 1 Letter of
        Credit, Tranche 2 Letter of Credit or Tranche X Letter of Credit, as the
        case may be, if such funding would cause the aggregate amount of
        outstanding unreimbursed fundings by such Bank of drawings on Letters of
        Credit under such applicable Tranche to exceed such Bank's Letter of
        Credit Committed Amount under such applicable Tranche.

        (c) OBLIGATIONS ABSOLUTE. Notwithstanding any other provision hereof,
each Bank hereby agrees that its obligation to participate in each Participated
Letter of Credit issued in accordance herewith, its obligation to make the
payments specified in Section 2.07 hereof, and the right of the Issuing Bank to
receive such payments in the manner specified therein, are each absolute,
irrevocable and unconditional and shall not be affected by any event, condition
or circumstance whatever. The failure of any Bank to make any such payment shall
not relieve any other Bank of its funding obligation hereunder on the date due,
but no Bank shall be responsible for the failure of any other Bank to meet its
funding obligations hereunder.

        2.07. PARTICIPATED LETTER OF CREDIT DRAWINGS AND REIMBURSEMENTS.

        (a) ACCOUNT PARTY'S REIMBURSEMENT OBLIGATION. Each Account Party hereby
agrees to reimburse the Issuing Bank, by making payment to the Agent for the
account of the Issuing Bank in accordance with Section 2.16(a) hereof on the
date of each LC Disbursement made by the Issuing Bank under any Participated
Letter of Credit issued for such Account Party's account (or, if later, the date
which is one (1) Business Day after notice of such LC Disbursement or of the
drawing giving rise to such LC Disbursement is given to XL Capital), without,
protest or demand, all of which are hereby waived, and an action therefor shall
immediately accrue. Each Account Party agrees that it will make such payment to
the Agent for the account of the Issuing Bank in the same currency as the
currency of the payment by the Issuing Bank under such Participated Letter of
Credit. To the extent such payment is not timely made, such Account Party hereby
agrees to pay to the Agent, for the account of the Issuing Bank, on demand,
interest on any Letter of Credit Unreimbursed Draws for each day from and
including the date of such payment by the Issuing Bank until paid (before and
after judgment) in accordance with Section 2.16(a) hereof, at the rate per annum
set forth in Section 2.16(b) hereof.

        (b) PAYMENT BY BANKS ON ACCOUNT OF UNREIMBURSED DRAWS. If the Issuing
Bank makes an LC Disbursement under any Participated Letter of Credit and is not
reimbursed in full therefor on such payment date in accordance with Section
2.07(a) hereof, the Issuing Bank will promptly notify the Agent thereof (which
notice may be by telephone), and the Agent shall forthwith notify each Bank
(which notice may be by telephone promptly confirmed in writing) thereof. No
later than the Agent's close of business on the date such notice is given (if
notice is given by 2:00 o'clock p.m., Pittsburgh time) or 10:00 o'clock a.m.,
Pittsburgh time the following day (if notice is given after 2:00 o'clock p.m.,
Pittsburgh time) , each Bank will pay to the Agent, for the account of the
Issuing Bank, in immediately available funds, an amount equal to such Bank's Pro
Rata share of the unreimbursed portion of such LC Disbursement by the Issuing
Bank, PROVIDED such notice is given no later than 2:00 o'clock p.m., Pittsburgh
time and subject to Section 2.06(b). Each Bank agrees that such payment to the
Agent for the account of the Issuing Bank shall be in the same currency as the
currency of the payment by the Issuing Bank under the Participated Letter of
Credit. If and to the extent that any Bank fails to make such payment to the
Issuing Bank on such date, such Bank shall pay such amount on demand, together
with interest, for the Issuing Bank's own account, for each day from and
including the date of the Issuing Bank's payment to and including the date of
repayment to the Issuing Bank

                                       21
<PAGE>

(before and after judgment) at rate per annum for each day from and including
the date of such payment by the Issuing Bank to and including the second
Business Day thereafter equal to the Applicable Interest Rate.

        (c) DISTRIBUTIONS TO BANKS. If, at any time, after there occurs a Letter
of Credit Unreimbursed Draw with respect to a Participated Letter of Credit and
the Issuing Bank has received from any Bank such Bank's share of such Letter of
Credit Unreimbursed Draw, and the Issuing Bank receives any payment or makes any
application of funds on account of the Letter of Credit Reimbursement Obligation
arising from such Letter of Credit Unreimbursed Draw, the Issuing Bank will pay
to the Agent, for the account of such Bank , such Bank's Pro Rata share of such
payment.

        (d) RESCISSION. If any amount received by the Issuing Bank on account of
any Letter of Credit Reimbursement Obligation under a Participated Letter of
Credit shall be avoided, rescinded or otherwise returned or paid over by the
Issuing Bank for any reason at any time, whether before or after the termination
of this Agreement (or the Issuing Bank believes in good faith that such
avoidance, rescission, return or payment is required, whether or not such matter
has been adjudicated), each such Bank will, promptly upon notice from the Agent
or the Issuing Bank, pay over to the Agent for the account of the Issuing Bank
its Pro Rata share of such amount, together with its Pro Rata share of any
interest or penalties payable with respect thereto.

        2.08. EQUALIZATION. If any Bank receives any payment or makes any
application on account of its Letter of Credit Participating Interest, such Bank
shall forthwith pay over to the Issuing Bank, in Dollars and in like kind of
funds received or applied by it the amount in excess of such Bank's ratable
share of the amount so received or applied.

        2.09. OBLIGATIONS ABSOLUTE. The Account Parties' obligations to
reimburse LC Disbursements in respect of any Participated Letter of Credit as
provided herein shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement under any and
all circumstances whatsoever and irrespective of (i) any lack of validity or
enforceability of any Participated Letter of Credit, or any term or provision
therein, (ii) any draft or other document presented under a Participated Letter
of Credit proving to be forged, fraudulent or invalid in any respect or any
statement therein being untrue or inaccurate in any respect, (iii) payment by
the Issuing Bank under a Participated Letter of Credit against presentation of a
draft or other document that does not comply strictly with the terms of such
Participated Letter of Credit, (iv) at any time or from time to time, without
notice to any Account Party, the time for any performance of or compliance with
any of such reimbursement obligations of any other Account Party shall be
waived, extended or renewed, (v) any of such reimbursement obligations of any
other Account Party shall be amended or otherwise modified in any respect, or
any guarantee of any of such reimbursement obligations shall be released,
substituted or exchanged in whole or in part or otherwise dealt with, (vi) the
occurrence of any Default, (vii) the existence of any proceedings of the type
described in clause (g) or (h) of Section 7.01 with respect to any other Account
Party or any guarantor of any of such reimbursement obligations, (viii) any lack
of validity or enforceability of any of such reimbursement obligations against
any other Account Party or any guarantor of any of such reimbursement
obligations, or (ix) any other event or circumstance whatsoever, whether or not
similar to any of the foregoing, that might, but for the provisions of this
Section, constitute a legal or equitable discharge of the obligations of any
Account Party hereunder.

                Neither the Agent, the Banks nor the Issuing Bank, nor any of
their respective Related Parties, shall have any liability or responsibility by
reason of or in connection with the payment or failure to make any payment under
a Participated Letter of Credit (irrespective of any of the circumstances
referred to in the preceding sentence) as a result of determining whether drafts

                                       22
<PAGE>

or other documents presented under a Participated Letter of Credit comply with
the terms thereof, or any error, omission, interruption, loss or delay in
transmission or delivery of any draft, notice or other communication under or
relating to any Participated Letter of Credit (including any document required
to make a drawing thereunder), any error in interpretation of technical terms or
any consequence arising from causes beyond the control of the Issuing Bank;
PROVIDED that the foregoing shall not be construed to excuse the Issuing Bank
from sole and exclusive liability to the Account Parties to the extent of any
direct damages (as opposed to consequential damages, claims in respect of which
are hereby waived by the Account Parties to the extent permitted by applicable
law) suffered by the Account Parties that are caused by the Issuing Bank's gross
negligence or willful misconduct when determining whether drafts and other
documents presented under a Participated Letter of Credit comply with the terms
thereof. The parties hereto expressly agree that:

                (i) the Issuing Bank may accept documents that appear on their
        face to be in substantial compliance with the terms of a Participated
        Letter of Credit without responsibility for further investigation,
        regardless of any notice or information to the contrary, and may make
        payment upon presentation of documents that appear on their face to be
        in substantial compliance with the terms of such Participated Letter of
        Credit;

                (ii) the Issuing Bank shall have the right, in its sole
        discretion, to decline to accept such documents and to make such payment
        if such documents are not in strict compliance with the terms of such
        Participated Letter of Credit; and

                (iii) this sentence shall establish the standard of care to be
        exercised by the Issuing Bank when determining whether drafts and other
        documents presented under a Participated Letter of Credit comply with
        the terms thereof (and the parties hereto hereby waive, to the extent
        permitted by applicable law, any standard of care inconsistent with the
        foregoing).

        2.10. CERTAIN PROVISIONS RELATING TO THE ISSUING BANK.

        (a) GENERAL. The Issuing Bank shall have no duties or responsibilities
except those expressly set forth in this Agreement and the other Transaction
Documents, and no implied duties or responsibilities on the part of the Issuing
Bank shall be read into this Agreement or any Transaction Document or shall
otherwise exist. The duties and responsibilities of the Issuing Bank to the
other Bank Parties under this Agreement and the other Transaction Documents
shall be mechanical and administrative in nature, and the Issuing Bank shall not
have a fiduciary relationship in respect of any Bank Party or any other Person.
The Issuing Bank shall not be liable for any action taken or omitted to be taken
by it under or in connection with this Agreement or any other Transaction
Document, unless caused by its own gross negligence or willful misconduct. The
Issuing Bank shall not be under any obligation to ascertain, inquire or give any
notice relating to (i) the performance or observance of any of the terms or
conditions of this Agreement or any other Transaction Document on the part of
any Account Party, (ii) the business, operations, condition (financial or
otherwise) or prospects of the Account Parties or any other Person, or (iii) the
existence of any Event of Default or Potential Default. The Issuing Bank shall
not be under any obligation, either initially or on a continuing basis, to
provide the Agent or any Bank with any notices, reports or information of any
nature, whether in its possession presently or hereafter, except for such
notices, reports and other information expressly required by this Agreement to
be so furnished. The Issuing Bank shall not be responsible for the execution,
delivery, effectiveness, enforceability, genuineness, validity or adequacy of
this Agreement or any other Transaction Document to the extent dependent upon
any Person other than the Issuing Bank.

        (b) ADMINISTRATION. The Issuing Bank may rely upon any notice or other
communication of any nature (written or oral, including but not limited to
telephone conversations, whether or not such

                                       23
<PAGE>

notice or other communication is made in a manner permitted or required by this
Agreement or any Transaction Document) purportedly made by or on behalf of the
proper party or parties, and the Issuing Bank shall not have any duty to verify
the identity or authority of any Person giving such notice or other
communication. The Issuing Bank may consult with legal counsel (including,
without limitation, in-house counsel for the Issuing Bank or in-house or other
counsel for the Account Parties), independent public accountants and any other
experts selected by it from time to time, and the Issuing Bank shall not be
liable for any action taken or omitted to be taken in good faith in accordance
with the advice of such counsel, accountants or experts. Whenever the Issuing
Bank shall deem it necessary or desirable that a matter be proved or established
with respect to any Account Party or Bank Party, such matter may be established
by a certificate of such Account Party or Bank Party, as the case may be, and
the Issuing Bank may conclusively rely upon such certificate. The Issuing Bank
shall not be deemed to have any knowledge or notice of the occurrence of any
Event of Default or Potential Default unless the Issuing Bank has received
notice from a Bank or any Credit Party referring to this Agreement, describing
such Event of Default or Potential Default, and stating that such notice is a
"notice of default". If the Issuing Bank receives such a notice, the Issuing
Bank shall give prompt notice thereof to the Agent.

        (c) INDEMNIFICATION OF ISSUING BANK BY BANKS. Each Bank hereby agrees to
reimburse and indemnify the Issuing Bank and each of its directors, officers,
employees and agents (to the extent not reimbursed by the Account Parties and
without limitation of the obligations of the Account Parties to do so), Pro
Rata, from and against any and all amounts, losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs or
disbursements of any kind or nature (including, without limitation, the
reasonable fees and disbursements of counsel (other than in-house counsel) for
the Issuing Bank or such other Person in connection with any investigative,
administrative or judicial proceeding commenced or threatened, whether or not
the Issuing Bank or such other Person shall be designated a party thereto) that
may at any time be imposed on, incurred by or asserted against the Issuing Bank,
in its capacity as such, or such other Person, as a result of, or arising out
of, or in any way related to or by reason of, this Agreement, any other
Transaction Document, any transaction from time to time contemplated hereby or
thereby, or any transaction financed in whole or in part or directly or
indirectly with the proceeds of any Participated Letter of Credit, PROVIDED,
that no Bank shall be liable for any portion of such amounts, losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements resulting from the gross negligence or
willful misconduct of the Issuing Bank or such other Person, as finally
determined by a court of competent jurisdiction.

        (d) ISSUING BANK IN ITS INDIVIDUAL CAPACITY. With respect to its
commitment hereunder and the Obligations owing to it, the Issuing Bank shall
have the same rights and powers under this Agreement and each other Transaction
Document as any other Bank and may exercise the same as though it were not the
Issuing Bank, and the term "Banks" and like terms shall include the Issuing Bank
in its individual capacity as such. The Issuing Bank and its affiliates may,
without liability to account, make loans to, accept deposits from, acquire debt
or equity interests in, act as trustee under indentures of, act as agent under
other credit facilities for, and engage in any other business with, any Credit
Party and any stockholder, subsidiary or affiliate of any Credit Party, as
though the Issuing Bank were not the Issuing Bank hereunder.

        2.11. FEES.

        (a) LETTER OF CREDIT FEE. Each Account Party shall pay or cause to be
paid to the Agent for the account of each Bank, in accordance with its Letter of
Credit Commitment Percentage , a fee (the "Letter of Credit Fee") for Letters of
Credit (based on a year of 360 days and actual days

                                       24
<PAGE>

elapsed), for each Letter of Credit issued for the account of such Account Party
for each day from and including the date of issuance thereof to and including
the date of expiration or termination thereof, on the Letter of Credit Undrawn
Availability on such day at a rate per annum equal to 0.20% for each Level One
Day, 0.30% for each Level Two Day and 0.40% for each Level Three Day. Such
Letter of Credit Fee shall be due and payable for the preceding period for which
such fee has not been paid on each of the following dates: (i) each Regular
Payment Date, (ii) the date of each drawing on such Letter of Credit, and (iii)
the date of expiration or termination of such Letter of Credit. If any Letter of
Credit Fee payment is made on a day which is not a Valuation Date, the amount of
such Letter of Credit Fee attributable to the period from the preceding
Valuation Date until such day shall be determined by reference to the rate
applicable on such preceding Valuation Date, subject to retroactive adjustment
on the next succeeding Valuation Date. The Agent shall provide to XL Capital on
a monthly basis a certificate, showing in reasonable detail (with reference to
the valuation report as of the last business day of the applicable month
provided by the Custodian to the Agent pursuant to the Custodian's
Acknowledgments (as defined in the Pledge Agreement)) the Agent's calculation of
the Letter of Credit Fee.

        (b) ADMINISTRATION FEES. Each Account Party shall pay to the Agent, for
the sole account of the Issuing Bank, such other administration, maintenance,
amendment, drawing and negotiation fees as are customarily charged by the
Issuing Bank to its customers generally at the time in question (a list of which
customary charges as of the date of this Agreement has been provided by the
Issuing Bank to XL Capital) or are otherwise agreed between the Issuing Bank and
the Account Parties.

        (c) COMMITMENT FEE. XL Capital agrees to pay to the Agent for the
account of each Bank a commitment fee (the "Commitment Fee") for each day during
the period from the Effective Date to and including the Expiration Date
calculated (based on a year of 360 days and actual days elapsed) at a per annum
rate equal to 0.06% payable on the unused portion of such Bank's Letter of
Credit Committed Amount in effect on such day. Such fee shall be payable on each
Regular Payment Date and on the Expiration Date for the preceding period for
which such fee has not been paid.

        (d) FACING FEE FOR PARTICIPATED LETTERS OF CREDIT. Each Account Party
shall pay or cause to be paid to the Agent, for the sole account of the Issuing
Bank, a letter of credit facing fee (the "Facing Fee") for each Participated
Letter of Credit issued for the account of such Account Party for each day
including the date of issuance thereof to and including the date of expiration
or termination thereof, on the aggregate Letter of Credit Undrawn Availability
of all of such Letters of Credit at a rate per annum, based on a year of 360
days and actual days elapsed, agreed to by the Agent and XL Capital prior to the
Closing Date. Such Facing Fee shall be due and payable on each Regular Payment
Date and on the Expiration Date for the preceding period for which such fee has
not been paid.

        (e) INITIAL FEE. XL Capital agrees to pay on the Closing Date to the
Agent for the account of each Bank an initial fee equal to five basis points,
payable on such Bank's Committed Amount on the date hereof.

        2.12. REDUCTION OF THE COMMITTED AMOUNTS. XL Capital may at any time or
from time to time reduce Pro Rata the Letter of Credit Committed Amounts of the
Banks to an aggregate amount (which may be zero) not less than the Letter of
Credit Exposure. Any reduction of the Letter of Credit Committed Amounts shall
be in an aggregate minimum amount of $25,000,000 and in an amount which is an
integral multiple of $5,000,000. Reduction of the Letter of Credit Committed
Amounts shall be made by providing not less than five (5) Business Days' notice
(which notice shall be irrevocable) to such effect to the Agent, which will
promptly advise the Banks of such notice. After the date specified in such
notice, the Commitment Fee shall be calculated upon the Letter of Credit
Committed Amounts as so reduced.

                                       25
<PAGE>

        2.13. PURPOSE OF LETTERS OF CREDIT. The Account Parties agree that each
Letter of Credit shall be used by the Account Party for whom it is issued as a
standby letter of credit for general corporate purposes in the ordinary course
of business of such Account Party. The provisions of this Section 2.13 represent
only an obligation of the Account Parties to the Agent and the Banks; neither
the Agent nor the Issuing Bank shall have any obligation to the Banks to
ascertain the purpose of any Letter of Credit, and, without limiting the
generality of the provisions of Section 2.06(b) hereof, the rights and
obligations of the Banks and the Agent among themselves shall not be impaired or
affected by a breach of this Section 2.13.

        2.14. FURTHER ASSURANCES. Each Account Party and each Guarantor hereby
agrees, from time to time, to do and perform any and all acts and to execute any
and all further instruments reasonably requested by the Issuing Bank more fully
to effect the purposes of this Agreement and the issuance of the Letters of
Credit hereunder.

        2.15. LETTER OF CREDIT APPLICATIONS. The representations, warranties and
covenants by the Account Parties under, and the rights and remedies of the
Issuing Bank under, the Continuing Letter of Credit Agreements and any Letter of
Credit Application relating to any Letter of Credit are in addition to, and not
in limitation or derogation of, representations, warranties and covenants by the
Account Parties under, and rights and remedies of the Issuing Bank and the Banks
under, this Agreement, the Transaction Documents, and applicable Law. Each
Account Party acknowledges and agrees that all rights of the Issuing Bank under
any Letter of Credit Application shall inure to the benefit of each Bank to the
extent of its Letter of Credit Commitment Percentage as fully as if such Bank
was a party to such Letter of Credit Application. In the event of any
inconsistency between the terms of this Agreement and any Letter of Credit
Application, this Agreement shall prevail.

        2.16. PAYMENTS GENERALLY; INTEREST AND INTEREST ON OVERDUE AMOUNTS.

        (a) PAYMENTS GENERALLY. All payments to be made by an Account Party in
respect of fees, indemnity, expenses or other amounts due from such Account
Party hereunder or under any Transaction Document shall be payable in Dollars at
12:00 o'clock Noon, Pittsburgh time, on the day when due without presentment,
demand, protest or notice of any kind, all of which are hereby expressly waived,
and an action therefor shall immediately accrue, without setoff, counterclaim,
withholding or other deduction of any kind or nature. Except for payments under
Sections 2.17, 2.18 and 9.04 hereof, such payments shall be made to the Agent at
its Office in Dollars in funds immediately available at such Office. Payments
under Sections 2.17, 2.18 and 9.04 hereof shall be made to the applicable Bank
at such domestic account as it shall specify to the Account Parties from time to
time in funds immediately available at such account. Any payment or prepayment
received by the Agent or such Bank after 12:00 o'clock Noon, Pittsburgh time, on
any day shall be deemed to have been received on the next succeeding Business
Day. The Agent shall distribute to the Banks all such payments received by it
from an Account Party as promptly as practicable after receipt by the Agent.

        (b) INTEREST AND INTEREST ON OVERDUE AMOUNTS. Interest on Letter of
Credit Reimbursement Obligations shall accrue at a rate per annum (based on a
year of 360 days and actual days elapsed) which for each day shall be equal to
the then-current Applicable Interest Rate beginning on the day that the related
Letter of Credit payment is made and shall be due and payable on the day that
the Letter of Credit Reimbursement Obligation is due and payable in accordance
with Section 2.03(a) or 2.07(a) hereof. To the extent permitted by law, after
there shall have become due (by acceleration or otherwise) fees, indemnity,
expenses or any other amounts due from the Account Parties hereunder or under
any other Transaction Document, such amounts shall bear interest for each day
until paid (before and after judgment), payable on demand, at a rate per annum
(in each case based on a year of 360 days

                                       26
<PAGE>

and actual days elapsed) which for each day shall be equal to 2% above the
then-current Applicable Interest Rate. To the extent permitted by law, interest
accrued on any amount which has become due hereunder or under any Transaction
Document shall compound on a day-by-day basis, and hence shall be added daily to
the overdue amount to which such interest relates.

        2.17. ADDITIONAL COMPENSATION IN CERTAIN CIRCUMSTANCES. If the
introduction of or any change in, or any change in the interpretation or
application of, any Law, regulation or guideline by any Governmental Authority
charged with the interpretation or administration thereof or compliance with any
request or directive of any applicable Governmental Authority (whether or not
having the force of law):

                (i)     subjects any Bank to any tax or changes the basis of
        taxation with respect to this Agreement, the Letters of Credit or
        payments by the Account Parties of fees or other amounts due from the
        Account Parties hereunder or under the other Transaction Documents
        (except for taxes on the overall net income or overall gross receipts of
        such Bank imposed by the jurisdictions (federal, state and local) in
        which the Bank's principal office is located),

                (ii)    imposes, modifies or deems applicable any reserve,
        special deposit or similar requirement against credits or commitments to
        extend credit extended by, assets (funded or contingent) of, deposits
        with or for the account of, other acquisitions of funds by, such Bank,

                (iii)   imposes, modifies or deems applicable any capital
        adequacy or similar requirement (A) against assets (funded or
        contingent) of, or credits or commitments to extend credit extended by,
        any Bank or (B) otherwise applicable to the obligations of any Bank
        under this Agreement, or

                (iv)    imposes upon any Bank any other condition or expense
        with respect to this Agreement or the issuance of any Letter of Credit,

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon any
Bank or, in the case of clause (iii) hereof, any Person controlling a Bank, with
respect to this Agreement or the issuance of any Letter of Credit (or, in the
case of any capital adequacy or similar requirement, to have the effect of
reducing the rate of return on such Bank's or controlling Person's capital,
taking into consideration such Bank's or controlling Person's policies with
respect to capital adequacy so long as such policies are reasonable in light of
prevailing market practice at the time) by an amount which such Bank deems to be
material, such Bank may from time to time notify the Account Parties of the
amount determined in good faith (using any averaging and attribution methods) by
such Bank (which determination shall be conclusive) to be necessary to
compensate such Bank for such increase, reduction or imposition. Such amount
shall be due and payable by any applicable Account Party to such Bank five (5)
Business Days after such notice is given, together with an amount equal to
interest on such amount from the date two (2) Business Days after the date
demanded until such due date at the Prime Rate. A certificate by such Bank as to
the amount due and payable under this Section 2.17 from time to time and the
method of calculating such amount shall be conclusive. Each Bank agrees that it
will use good faith efforts to notify the Account Parties of the occurrence of
any event that would give rise to a payment under this Section 2.17; PROVIDED,
however that, so long as such notice is given within a reasonable period after
the occurrence of such event, any failure of such Bank to give any such notice
shall have no effect on the Account Parties' obligations hereunder.

                                       27

        2.18. TAXES.

        (a) PAYMENTS NET OF TAXES. All payments made by the Account Parties
under this Agreement or any other Transaction Document shall be made free and
clear of, and without reduction or withholding for or on account of, any present
or future income, stamp or other taxes, levies, imposts, duties, charges, fees,
deductions or withholdings, now or hereafter imposed, levied, collected,
withheld or assessed by any Governmental Authority, and all liabilities with
respect thereto, excluding

                (i) in the case of the Agent and each Bank, income or franchise
        taxes imposed on the Agent or such Bank by the jurisdiction under the
        laws of which the Agent or such Bank is organized or any political
        subdivision or taxing authority thereof or therein or as a result of a
        connection between such Bank and any jurisdiction other than a
        connection resulting solely from this Agreement and the transactions
        contemplated hereby, and

                (ii) in the case of each Bank, income or franchise taxes imposed
        by any jurisdiction in which such Bank's lending offices which issue
        Letters of Credit are located or any political subdivision or taxing
        authority thereof or therein

(all such non-excluded taxes, levies, imposts, deductions, charges or
withholdings being hereinafter called "Non-Excluded Taxes"), unless an Account
Party is required to withhold or deduct Non-Excluded Taxes. If any Non-Excluded
Taxes are required to be withheld or deducted from any amounts payable to the
Agent or any Bank under this Agreement or any other Transaction Document, the
applicable Account Party shall pay the relevant amount of such Non-Excluded
Taxes and the amounts so payable to the Agent or such Bank shall be increased to
the extent necessary to yield to the Agent or such Bank (after payment of all
Non-Excluded Taxes) interest or any such other amounts payable hereunder at the
rates or in the amounts specified in this Agreement and the other Transaction
Documents. Whenever any Non-Excluded Taxes are paid by an Account Party with
respect to payments made in connection with this Agreement or any other
Transaction Document, as promptly as possible thereafter, such Account Party
shall send to the Agent for its own account or for the account of such Bank, as
the case may be, a certified copy of an original official receipt received by
such Account Party showing payment thereof. If the Agent or a Bank determines in
its sole discretion in good faith that it has received a refund in respect of
any Non-Excluded Taxes as to which it has been indemnified by an Account Party,
or with respect to which an Account Party has paid additional amounts pursuant
to this Section 2.18, the Agent or such Bank shall promptly after the date of
such receipt pay over the amount of such refund to such Account Party (but only
to the extent of indemnity payments made, or additional amounts paid, by an
Account Party under this Section 2.18 with respect to Non-Excluded Taxes giving
rise to such refund and only to the extent that the Agent or such Bank has
determined that the amount of any such refund is directly attributable to
payments made under this Agreement), net of all reasonable expenses of the Agent
or such Bank (including additional Non-Excluded Taxes attributable to such
refund, as determined by the Agent or such Bank) and without interest (other
than interest, if any, paid by the relevant Governmental Authority with respect
to such refund). An Account Party receiving any such payment from the Agent or a
Bank shall, upon demand, pay to the Agent or such Bank any amount paid over to
such Account Party by the Agent or such Bank (plus penalties, interest or other
charges) in the event the Agent or such Bank is required to repay any portion of
such refund to such Governmental Authority. Nothing in this Section 2.18(a)
shall entitle an Account Party to have access to the records of the Agent or any
Bank, including, without limitation, tax returns.

        (b) INDEMNITY. Each Account Party hereby indemnifies the Agent and each
of the Banks for the full amount of all Non-Excluded Taxes attributable to
payments by or on behalf of such Account

                                       28
<PAGE>

Party hereunder or under any of the other Transaction Documents, any
Non-Excluded Taxes paid by the Agent or such Bank, as the case may be, any
present or future claims, liabilities or losses with respect to or resulting
from any omission to pay or delay in paying any Non-Excluded Taxes (including
any incremental Non-Excluded Taxes, interest or penalties that may become
payable by the Agent or such Bank as a result of any failure to pay such
Non-Excluded Taxes, except by reason of unreasonable delay by the Agent or Bank
in notifying an Account Party or in making payment after payment was received
from an Account Party), whether or not such Non-Excluded Taxes were correctly or
legally asserted. Such indemnification shall be made within 30 days from the
date such Bank or the Agent, as the case may be, makes written demand therefor.

        (c) WITHHOLDING AND BACKUP WITHHOLDING. Each Bank that is incorporated
or organized under the laws of any jurisdiction other than the United States or
any State thereof agrees that, on or prior to the date the first payment is due
to be made to it hereunder or under any other Transaction Document, it will
furnish to the Account Parties and the Agent

                (i) two (2) valid, duly completed copies of United States
        Internal Revenue Service Form 4224 or United States Internal Revenue
        Form 1001 or successor applicable form, as the case may be, certifying
        in each case that such Bank is entitled to receive payments under this
        Agreement and the other Transaction Documents without deduction or
        withholding of any United States federal income taxes and

                (ii) a valid, duly completed Internal Revenue Service Form W-8
        or W-9 or successor applicable form, as the case may be, to establish an
        exemption from United States backup withholding tax.

Each Bank which so delivers to the Account Parties and the Agent a Form 1001 or
4224 and Form W-8 or W-9, or successor applicable forms, agrees to deliver to
the Account Parties and the Agent two (2) further copies of the said Form 1001
or 4224 and Form W-8 or W-9, or successor applicable forms, or other manner of
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or otherwise is required to be resubmitted as a
condition to obtaining an exemption from withholding tax, or after the
occurrence of any event requiring a change in the most recent form previously
delivered by it, and such extensions or renewals thereof as may reasonably be
requested by the Account Parties and the Agent, certifying in the case of a Form
1001 or Form 4224 that such Bank is entitled to receive payments under this
Agreement or any other Transaction Document without deduction or withholding of
any United States federal income taxes, unless in any such cases an event
(including any changes in Law) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Bank from duly completing and delivering any such
letter or form with respect to it and such Bank advises the Account Parties and
the Agent that it is not capable of receiving payments without any deduction or
withholding of United States federal income tax, and in the case of a Form W-8
or W-9, establishing an exemption from United States backup withholding tax, in
which case Section 2.13(a) and (b) shall apply to all further payments.

        2.19. EXTENSIONS OF EXPIRATION DATE. XL Capital may, at its option, give
the Agent and the Issuing Bank written notice (an "EXTENSION REQUEST") at any
time not more than ninety (90) days, nor less than forty-five (45) days, prior
to the Expiration Date in effect at such time (the "CURRENT EXPIRATION DATE") of
XL Capital's desire to extend the Expiration Date to a date which is not later
than 364 days after the Current Expiration Date. The Agent shall promptly inform
the Banks of such Extension Request. Each Bank which agrees to such Extension
Request shall deliver to the Agent its express written consent thereto no later
than thirty (30) days prior to the Current

                                       29
<PAGE>

Expiration Date. No extension shall become effective unless the express written
consent thereto by the Required Commitment Banks and the Issuing Bank is
received by the Agent on or before the thirtieth (30th) day prior to the Current
Expiration Date. If the Issuing Bank and the Required Commitment Banks, but not
all Commitment Banks, have expressly consented in writing to such Extension
Request by such thirtieth (30th) day, then the Agent shall so notify XL Capital
and XL Capital may, effective as of the Current Expiration Date, take one or
both of the following actions: (i) replace any Commitment Bank which has not
agreed to such Extension Request (a "NONEXTENDING BANK") with another commercial
lending institution satisfactory to the Issuing Bank (a "REPLACEMENT BANK") by
giving notice of the name of such Replacement Bank to the Agent and the Issuing
Bank not later than five (5) Business Days prior to the then Current Expiration
Date and by securing the agreement, in form and substance satisfactory to the
Issuing Bank, of each beneficiary under each outstanding Syndicated Letter of
Credit to the substitution of such Replacement Bank for such Nonextending Bank
under each such Syndicated Letter of Credit, and (ii) elect to implement a
Conversion to Tranche System as contemplated by Section 2.20 hereof (or, if the
Conversion to Tranche System has previously been implemented, elect to implement
a Supplement to Tranche System as contemplated by Section 2.20 hereof). In the
event that a Nonextending Bank is to be replaced by a Replacement Bank, such
Nonextending Bank shall, upon payment to it of all amounts owing to it on the
date of its replacement, assign all of its interests hereunder to such
Replacement Bank in accordance with the provisions of Section 9.13(c) hereof. If
the Issuing Bank and the Required Commitment Banks shall have consented to such
Extension Request, then, on the Current Expiration Date, the Expiration Date
shall be deemed to have been extended to, and shall be, the date specified in
such Extension Request; PROVIDED that if the Required Commitment Banks, but not
all Commitment Banks, shall have consented to such Extension Request and XL
Capital has elected to implement a Conversion to Tranche System, then the
Expiration Date shall be deemed to have been so extended only with respect to
Participated Letters of Credit and not with respect to Syndicated Letters of
Credit. The Agent shall promptly after any such extension advise the Banks of
any changes in the Letter of Credit Committed Amounts and the Letter of Credit
Commitment Percentages, as well as any changes effected by the election of the
Conversion to Tranche System or a Supplement to Tranche System.

        2.20. TRANCHES. (a) CERTAIN DEFINITIONS. As used in this Agreement the

                        "SPECIAL EXPIRATION DATE" means the Expiration Date
                which is in effect at a time when each of the following has
                occurred: (i) XL Capital has made an Extension Request pursuant
                to Section 2.19 hereof, (ii) such Extension Request has been

                extended to a date after the L/C Termination Date which was in
                effect on such second Special Expiration Date and shall not
                include any Tranche 1 Letter of

                                       31
<PAGE>

                Credit (it being understood that a Participated Letter of Credit
                may change from a Tranche 1 Letter of Credit to a Tranche 2
                Letter of Credit as a result of the extension, after the first
                Special Expiration Date, of its L/C Termination Date).

                        "TRANCHE 3 LETTER OF CREDIT" and "TRANCHE 4 LETTER OF
                CREDIT" have the meanings set forth in the definition of the
                term "Tranche X".

                        "TRANCHE X" shall mean Tranche 3 if there are existing
                Tranche 2 Letters of Credit but not Tranche 3 Letters of Credit,

                integral succession. The terms "Tranche X Bank", "Tranche X
                Letter of Credit Commitment", "Tranche X Letter of Credit
                Committed Amount" and "Tranche X Letter of Credit Commitment
                Percentage" shall have comparable meanings. The term "Tranche X
                Letter of Credit" shall have a comparable meaning, but such
                meaning shall be consistent with the following: (i) the term
                "TRANCHE 3 LETTER OF CREDIT" means each Participated Letter of
                Credit which is issued prior to the third Special Expiration
                Date, but shall not include any such Participated Letter of
                Credit as to which the L/C Termination Date has been extended to

                such third Special Expiration Date and shall not include any
                Tranche 1 Letter or Credit or any Tranche 2 Letter of Credit;
                (ii) the term "TRANCHE 4 LETTER OF CREDIT" means each
                Participated Letter of Credit which is issued prior to the
                fourth Special Expiration Date, but shall not include any such
                Participated Letter of Credit as to which the L/C Termination
                Date has been extended to a date after the L/C Termination Date
                which was in effect on such fourth Special Expiration Date and
                shall not include any Tranche 1 Letter of Credit, any Tranche 2
                Letter of Credit or any Tranche 3 Letter of Credit; (iii) the
                terms "TRANCHE 5 LETTER OF CREDIT", "TRANCHE 6 LETTER OF
                CREDIT", and so on shall have comparable meanings (it being
                understood that a Participated Letter of Credit can change from
                one Tranche to another as a result of an extension of its L/C
                Termination Date).

        (b) CONVERSION TO TRANCHE SYSTEM. If XL Capital elects the Conversion to
Tranche System with respect to an Extension Request, the following shall occur:
(i) the Syndicated Letter of Credit Commitments of all of the Banks shall
terminate as of the first Special Expiration Date and the Letter of Credit
Commitments of Banks which, with respect to such Extension Request, are
Nonextending Banks shall terminate as of the Special Expiration Date related to
such Extension Request, but the Banks (other than Nonextending Banks which have
been replaced as contemplated by Section 2.19 hereof) shall remain parties to
this Agreement and shall retain all of their respective obligations with respect
to Tranche 1 Letters of Credit and shall retain their respective Letter of
Credit Interests in and with respect to Tranche 1 Letters of Credit; (ii) from
and after the Special Expiration Date related to such Extension Request, the
Letter of Credit Commitment of each Bank which has consented in writing to such
Extension Request shall be a "TRANCHE 2 LETTER OF CREDIT COMMITMENT" and the
Letter of Credit Participating Interested Committed Amount of such Bank shall be
its "TRANCHE 2 LETTER OF CREDIT COMMITTED AMOUNT"; (iii) the "TRANCHE 2 LETTER
OF CREDIT COMMITMENT PERCENTAGE" for each Tranche 2 Bank shall mean a fraction,
expressed as percentage, the numerator of which is such Tranche 2 Bank's Tranche
2 Letter of Credit Committed Amount and the denominator of which is the
aggregate Tranche 2 Letter of Credit Committed Amounts of all of the Tranche 2
Banks.

                                       32

        (c) SUPPLEMENT TO TRANCHE SYSTEM. If XL Capital elects a Supplement to
Tranche System with respect to an Extension Request, the following shall occur:
(i) the Letter of Credit Commitments of Banks which, with respect to such
Extension Request, are Nonextending Banks shall terminate, but such Nonextending
Banks shall remain parties to this Agreement and shall retain all of their
respective obligations with respect to Letters of Credit under existing Tranches
and shall retain their respective Letter of Credit Interests in and with respect
to existing Letters of Credit; (ii) from and after the Special Expiration Date
related to such Extension Request, the Letter of Credit Commitment of each Bank
which has consented in writing to such Extension Request shall be a "TRANCHE X
LETTER OF CREDIT COMMITMENT" and the Letter of Credit Committed Amount of such
Bank shall be its "TRANCHE X LETTER OF CREDIT COMMITTED AMOUNT"; (iii) the
"TRANCHE X LETTER OF CREDIT COMMITMENT PERCENTAGE" for each Tranche X Bank shall
mean a fraction, expressed as percentage, the numerator of which is such Tranche
X Bank's Tranche X Letter of Credit Committed Amount and the denominator of
which is the aggregate Tranche X Letter of Credit Committed Amounts of all of
the Tranche X Banks, all as contemplated by the definition of the term "Tranche
X" contained in paragraph (a) of this Section 2.20.

        2.21. BENCHMARK CREDIT RATING. If the long-term deposit rating of any
Bank shall decline below the Benchmark Credit Rating (as defined below), the
Issuing Bank shall have the right, but not the obligation, to cause such Bank to
be replaced as a party hereto by a Replacement Bank. In the event that any Bank
is to be replaced by a Replacement Bank, such Bank shall, upon payment to it of
all amounts owing to it on the date of its replacement, assign all of its
interests hereunder to such Replacement Bank in accordance with the provisions
of Section 9.13(c) hereof. The "BENCHMARK CREDIT RATING" is both (i) a long-term
deposit rating of at least A by Standard & Poor's and (ii) a long-term deposit
rating of at least A2 by Moody's. Each Credit Party agrees that it shall
cooperate with the Issuing Bank in connection with the identification of one or
more Replacement Banks if the Issuing Bank exercises its right set forth in the
first sentence of this Section 2.21.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES.

Each Credit Party represents and warrants that:

        3.01. ORGANIZATION; POWERS. Such Credit Party and each of its
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, has all requisite power and
authority to carry on its business as now conducted and, except where the
failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, is qualified to do business in,
and is in good standing in, every jurisdiction where such qualification is
required.

        3.02. AUTHORIZATION; ENFORCEABILITY. The Transactions are within such
Credit Party's and XL Investments' corporate powers and have been duly
authorized by all necessary corporate and, if required, by all necessary
shareholder action. This Agreement has been duly executed and delivered by such
Credit Party and constitutes a legal, valid and binding obligation of such
Credit Party, enforceable against such Credit Party in accordance with its
terms, except as such enforceability may be limited by (a) bankruptcy,
insolvency, reorganization, moratorium, examination or similar laws of general
applicability affecting the enforcement of creditors' rights and (b) the
application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

                                       33
<PAGE>

        3.03. GOVERNMENTAL APPROVALS; NO CONFLICTS. The Transactions (a) do not
require any consent or approval of (including any exchange control approval),
registration or filing with, or any other action by, any Governmental Authority,
except such as have been obtained or made and are in full force and effect, (b)
will not violate any applicable law or regulation or the charter, by-laws or
other organizational documents of such Credit Party or any of its Subsidiaries
or any order of any Governmental Authority, (c) will not violate or result in a
default under any material indenture, agreement or other instrument binding upon
such Credit Party or any of its Subsidiaries or assets, or give rise to a right
thereunder to require any payment to be made by any such Person, and (d) will
not result in the creation or imposition of any Lien on any asset of such Credit
Party or any of its Subsidiaries.

        3.04. FINANCIAL CONDITION; NO MATERIAL ADVERSE CHANGE.

        (a) FINANCIAL CONDITION. Such Credit Party has heretofore furnished to
the Banks the consolidated balance sheet and statements of income, stockholders'
equity and cash flows of such Credit Party and its consolidated Subsidiaries (A)
as of and for the fiscal years ended December 31, 1999 and December 31, 2000,
reported on by PricewaterhouseCoopers LLP, independent public accountants (as
provided in XL Capital's Report on Form 10-K filed with the SEC for the fiscal
year ended December 31, 2000), and (B) as of and for the fiscal quarter ended
September 30, 2001, as provided in XL Capital's Report on Form 10-Q filed with
the SEC for the fiscal quarter ended September 30, 2001. Such financial
statements present fairly, in all material respects, the financial position and
results of operations and cash flows of such Credit Party and its respective
consolidated Subsidiaries as of such dates and for such periods in accordance
with GAAP or (in the case of XL Europe, XL Insurance or XL Re) SAP, subject to
year-end audit adjustments and the absence of footnotes in the case of the
statements referred to in clause (B) of the first sentence of this paragraph.

        (b) NO MATERIAL ADVERSE CHANGE. Since December 31, 2000, there has been
no material adverse change in the assets, business, financial condition or
operations of such Credit Party and its Subsidiaries, taken as a whole, except
for losses caused by or relating to or arising out of the terrorist events of
September 11, 2001; PROVIDED HOWEVER, that XL Capital remains in compliance with
Section 6.06.

        3.05. PROPERTIES.

        (a) PROPERTY GENERALLY. Such Credit Party and each of its Subsidiaries
has good title to, or valid leasehold interests in, all its real and personal
property material to its business, subject only to Liens permitted by Section
6.03 and except for minor defects in title that do not interfere with its
ability to conduct its business as currently conducted or to utilize such
properties for their intended purposes.

        (b) INTELLECTUAL PROPERTY. Such Credit Party and each of its
Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, patents and other intellectual property material to its business,
and the use thereof by such Credit Party and its Subsidiaries does not infringe
upon the rights of any other Person, except for any such infringements that,
individually or in the aggregate, could not reasonably be expected to result in
a Material Adverse Effect.

        3.06. LITIGATION AND ENVIRONMENTAL MATTERS.

        (a) ACTIONS, SUITS AND PROCEEDINGS. Except as disclosed in Schedule 3.06
or as routinely encountered in claims activity, there are no actions, suits or
proceedings by or before any arbitrator or Governmental Authority now pending
against or, to the knowledge of such Credit Party, threatened against or
affecting such Credit Party or any of its Subsidiaries (i) as to which there is
a reasonable possibility of an adverse determination and that could reasonably
be expected,

                                       34
<PAGE>

individually or in the aggregate, to result in a Material Adverse Effect or (ii)
that involve this Agreement or the Transactions.

        (b) ENVIRONMENTAL MATTERS. Except as disclosed in Schedule 3.06 and
except with respect to any other matters that, individually or in the aggregate,
could not reasonably be expected to result in a Material Adverse Effect, neither
such Credit Party nor any of its Subsidiaries (i) has failed to comply with any
Environmental Law or to obtain, maintain or comply with any permit, license or
other approval required for its business under any Environmental Law, (ii) has
incurred any Environmental Liability, (iii) has received notice of any claim
with respect to any Environmental Liability or (iv) knows of any basis for any
Environmental Liability.

        3.07. COMPLIANCE WITH LAWS AND AGREEMENTS. Such Credit Party and each of
its Subsidiaries is in compliance with all laws, regulations and orders of any
Governmental Authority applicable to it or its property and all indentures,
agreements and other instruments binding upon it or its property, except where
the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. No Event of Default has
occurred and is continuing.

        3.08. INVESTMENT AND HOLDING COMPANY STATUS. Neither such Credit Party
nor XL Investments is (a) an "investment company" as defined in, or subject to
regulation under, the Investment Company Act of 1940 or (b) a "holding company"
as defined in, or subject to regulation under, the Public Utility Holding
Company Act of 1935.

        3.09. TAXES. Such Credit Party and each of its Subsidiaries has timely
filed or caused to be filed all Tax returns and reports required to have been
filed and has paid or caused to be paid all Taxes required to have been paid by
it, except (a) Taxes that are being contested in good faith by appropriate
proceedings and for which such Person has set aside on its books adequate
reserves or (b) to the extent that the failure to do so could not reasonably be
expected to result in a Material Adverse Effect.

        3.10. ERISA. No ERISA Event has occurred or is reasonably expected to
occur that, when taken together with all other such ERISA Events for which
liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect. The present value of all accumulated
benefit obligations under each Plan (based on the assumptions used for purposes
of Statement of Financial Accounting Standards No. 87) did not, as of the date
of the most recent financial statements reflecting such amounts, exceed the fair
market value of the assets of such Plan by an amount that could reasonably be
expected to result in a Material Adverse Effect.

        Except as could not reasonably be expected to result in a Material
Adverse Effect, (i) all contributions required to be made by any Credit Party or
any of their Subsidiaries with respect to a Non-U.S. Benefit Plan have been
timely made, (ii) each Non-U.S. Benefit Plan has been maintained in compliance
with its terms and with the requirements of any and all applicable laws and has
been maintained, where required, in good standing with the applicable
Governmental Authority and (iii) neither any Credit Party nor any of their
Subsidiaries has incurred any obligation in connection with the termination or
withdrawal from any Non-U.S. Benefit Plan.

        3.11. DISCLOSURE. The reports, financial statements, certificates or
other information furnished by such Credit Party or by XL Investments to the
Bank Parties in connection with the negotiation of this Agreement or delivered
hereunder (taken as a whole) do not contain any material misstatement of fact or
omit to state any material fact necessary to make the statements therein, in the
light of the circumstances under which they were made, not misleading; provided
that, with respect to projected financial information, such Credit Party
represents only that such information was prepared in good faith based upon
assumptions believed to be reasonable at the time.

                                       35
<PAGE>

        3.12. USE OF CREDIT. Neither such Credit Party nor any of its
Subsidiaries is engaged principally, or as one of its important activities, in
the business of extending credit for the purpose, whether immediate, incidental
or ultimate, of buying or carrying Margin Stock, and no Letter of Credit will be

annual financial statements of XL Capital so long as the financial information
required to be contained in such Report is substantially the same as the

Credit Party as presenting fairly in all material respects the financial
condition and results of operations of such Credit Party and its consolidated
Subsidiaries on a consolidated basis in accordance with GAAP or (in the case of
XL Europe, XL Insurance and XL Re) SAP, as the case may be, consistently
applied, subject to normal year-end audit adjustments and the absence of
footnotes (it being understood that delivery to the Banks of XL Capital's Report
on Form 10-Q filed with the SEC shall satisfy the financial statement delivery
requirements of this paragraph (c) to deliver the quarterly financial statements
of XL Capital so long as the financial information required to be contained in
such Report is substantially the same as the financial information required

Party by a Financial Officer (i) certifying as to whether an Event of Default

thereof and any action taken or proposed to be taken with respect thereto, (ii)
setting forth reasonably detailed calculations demonstrating compliance with
Sections 6.03, 6.05, 6.06 and 6.07 and (iii) stating whether any change in GAAP
or (in the case of XL Europe, XL Insurance and XL Re) SAP or in the application
thereof has occurred since the date of the audited financial statements referred
to in Section 3.04 and, if any such change has occurred, specifying the effect
of such change on the financial statements accompanying such certificate;

such certificate relates (i) the aggregate book value of assets which are

                                       39
<PAGE>

and (c) of this Section shall satisfy the requirement of this clause (i) of this
paragraph (g) if such reports set forth separately, in accordance with GAAP,
line items corresponding to such aggregate book values) and (ii) a calculation
showing the portion of each of such aggregate amounts which portion is
attributable to transactions among wholly-owned Subsidiaries of XL Capital; and

        (g) promptly following any request therefor, such other information
regarding the operations, business affairs and financial condition of XL Capital
or any of its Subsidiaries, or compliance with the terms of this Agreement, as
the Agent or any Bank may reasonably request.

        5.02. NOTICES OF MATERIAL EVENTS. Each Credit Party will furnish to the
Agent and each Bank prompt written notice of the following:

        (a) the occurrence of any Event of Default; and

        (b) any event or condition constituting, or which could reasonably be
expected to have a Material Adverse Effect.

        Each notice delivered under this Section shall be accompanied by a
statement of a Financial Officer or other executive officer of the relevant
Credit Party setting forth the details of the event or development requiring
such notice and any action taken or proposed to be taken by such Credit Party

and will cause each of its Subsidiaries to, maintain its corporate existence and
its material rights and franchises in full force and effect in its jurisdiction
of incorporation; provided that the foregoing shall not prohibit any merger or
consolidation permitted under Section 6.01. Each Credit Party will, and will
cause each of its Subsidiaries to, qualify and remain qualified as a foreign
corporation in each jurisdiction in which failure to receive or retain such
qualification would have a Material Adverse Effect.

        5.04. INSURANCE. Each Credit Party will, and will cause each of its
Subsidiaries to, maintain with financially sound and reputable insurers,
insurance with respect to its properties in such amounts as is customary in the
case of corporations engaged in the same or similar businesses having similar
properties similarly situated.

        5.05. MAINTENANCE OF PROPERTIES. Each Credit Party will, and will cause
each of its Subsidiaries to, maintain or cause to be maintained in good repair,
working order and condition the properties now or hereafter owned, leased or
otherwise possessed by and used or useful in its business and will make or cause
to be made all needful and proper repairs, renewals, replacements and
improvements thereto so that the business carried on in connection therewith may
be properly conducted at all times except if the failure to do so would not have
a Material Adverse Effect, provided, however, that the foregoing shall not
impose on such Credit Party or any Subsidiary of such Credit Party any
obligation in respect of any property leased by such Credit Party or such
Subsidiary in addition to such Credit Party's obligations under the applicable
document creating such Credit Party's or such Subsidiary's lease or tenancy.

        5.06. PAYMENT OF TAXES AND OTHER POTENTIAL CHARGES AND PRIORITY CLAIMS;
PAYMENT OF OTHER CURRENT LIABILITIES. Each Credit Party will, and will cause
each of its Subsidiaries to, pay or discharge:

taxes, assessments and other governmental charges or levies imposed upon it or
any of its properties or income;

                                       40
<PAGE>

        (b) on or prior to the date when due, all lawful claims of materialmen,
mechanics, carriers, warehousemen, landlords and other like Persons which, if
unpaid, might result in the creation of a Lien upon any such property; and

        (c) on or prior to the date when due, all other lawful claims which, if
unpaid, might result in the creation of a Lien upon any such property (other
than Liens not forbidden by Section 6.03) or which, if unpaid, might give rise
to a claim entitled to priority over general creditors of such Credit Party in
any proceeding under the Bermuda Companies Law or Bermuda Insurance Law, or any
insolvency proceeding, liquidation, receivership, rehabilitation, dissolution or
winding-up involving such Credit Party or such Subsidiary;

        provided that, unless and until foreclosure, distraint, levy, sale or
similar proceedings shall have been commenced, such Credit Party need not pay or
discharge any such tax, assessment, charge, levy or claim so long as the
validity thereof is contested in good faith and by appropriate proceedings
diligently conducted and so long as such reserves or other appropriate
provisions as may be required by GAAP or SAP, as the case may be, shall have
been made therefor and so long as such failure to pay or discharge does not have
a Material Adverse Effect.

        5.07. FINANCIAL ACCOUNTING PRACTICES. Such Credit Party will, and will
cause each of its consolidated Subsidiaries to, make and keep books, records and
accounts which, in reasonable detail, accurately and fairly reflect its
transactions and dispositions of its assets and maintain a system of internal
accounting controls sufficient to provide reasonable assurances that
transactions are recorded as necessary to permit preparation of financial
statements required under Section 5.01 in conformity with GAAP and SAP, as
applicable, and to maintain accountability for assets.

        5.08. COMPLIANCE WITH APPLICABLE LAWS. Each Credit Party will, and will
cause each of its Subsidiaries to, comply with all applicable Laws (including
but not limited to the Bermuda Companies Law and Bermuda Insurance Laws) in all
respects; provided that such Credit Party or any Subsidiary of such Credit Party
will not be deemed to be in violation of this Section as a result of any failure
to comply with any such Law which would not (i) result in fines, penalties,
injunctive relief or other civil or criminal liabilities which, in the
aggregate, would have a Material Adverse Effect or (ii) otherwise impair the
ability of such Credit Party to perform its obligations under this Agreement.

        5.09. USE OF LETTERS OF CREDIT. No Letter of Credit will be used,
whether directly or indirectly, for any purpose that entails a violation of any
of the Regulations of the Board, including Regulations U and X.

        5.10. CONTINUATION OF AND CHANGE IN BUSINESSES. Each Credit Party and
its Subsidiaries will continue to engage in substantially the same business or
businesses it engaged in (or proposes to engage in) on the date of this
Agreement and businesses related or incidental thereto.

        5.11. VISITATION. Each Credit Party will permit such Persons as any Bank
may reasonably designate to visit and inspect any of the properties of such
Credit Party, to discuss its affairs with its financial management, and provide
such other information relating to the business and financial condition of such
Credit Party at such times as such Bank may reasonably request. Each Credit
Party hereby authorizes its financial management to discuss with any Bank the
affairs of such Credit Party.

        Pledge Agreement itself or the transactions contemplated thereby

hereby waived by the Account Parties; and in case of any event with respect to
any Account Party described in Section 7.01(g) or (h), the Letter of Credit

                                  ARTICLE VIII

                                    THE AGENT

        8.01. APPOINTMENT. (a) Each Bank hereby appoints Mellon Bank, N.A. to
act as Agent for such Bank under this Agreement and the other Transaction
Documents. Subject to Section 8.09 hereof, each Bank hereby irrevocably
authorizes the Agent to take such action on behalf of such Bank under the
provisions of this Agreement and the other Transaction Documents, and to
exercise such powers and to perform such duties, as are expressly delegated to
or required of the Agent by the terms hereof or thereof, together with such
powers as are reasonably incidental thereto. Mellon Bank, N.A. hereby agrees to
act as Agent on behalf of the Banks on the terms and conditions set forth in
this Agreement and the other Transaction Documents, subject to its right to
resign as provided in Section 8.10 hereof. Each Bank hereby irrevocably
authorizes the Agent to execute and deliver each of the Transaction Documents
and to accept delivery of such of the other Transaction Documents as may not
require execution by the Agent. Each Bank agrees that the rights and remedies
granted to the Agent under the Transaction Documents shall be exercised
exclusively by the Agent, and that no Bank shall have any right individually to
exercise any such right or remedy, except to the extent expressly provided
herein or therein.

        (b) Each Bank agrees that Mellon Bank, N. A. may act as collateral agent
in connection with a Future Collateral Allocation Transaction. As used herein,
the term "Future Collateral Allocation Transaction" means a transaction which
includes, among other things, the following elements: (i) a Credit Party shall
have arranged one or more separate financing transactions with credit providers
(which may, but need not, include any of the Banks) for which securities
entitlements in the Designated Accounts serve as collateral at a time when
securities entitlements in the Designated Accounts serve as collateral for the
Obligations under this Agreement; (ii) Mellon Bank, N. A. shall have agreed to
serve as collateral agent both for the Issuing Bank, the Agent and the Banks
under this Agreement and the Pledge Agreement and for the parties providing the
separate financing described in clause (i) of this paragraph; (iii) arrangements
shall have been made pursuant to which specific securities entitlements within
the Designated Accounts are allocated as collateral for the Obligations

                                       47
<PAGE>

under this Agreement and other specific securities entitlements within the
Designated Accounts are allocated as collateral for such other financings; and
(iv) the Required Banks and the Issuing Bank shall have approved all of such
arrangements and the documents implementing the same, including amendments to
this Agreement and the Pledge Agreement. The granting by a Credit Party to a
person other than Mellon Bank, N. A. of a security interest in securities
entitlements which are maintained in a Designated Account but which do not
constitute Collateral (as defined in the Pledge Agreement) shall not be a
"Future Collateral Allocation Transaction" and, accordingly, shall not require
approval of the Required Banks but shall be subject to the applicable provisions
of the Custodian's Acknowledgments, as defined in the Pledge Agreement.

        (c). The Arrangers shall have no duties or obligations in such capacity
under this Agreement.

        8.02. GENERAL NATURE OF AGENT'S DUTIES. Notwithstanding anything to the
contrary elsewhere in this Agreement or in any other Transaction Document:

                (a) The Agent shall have no duties or responsibilities except
        those expressly set forth in this Agreement and the other Transaction
        Documents, and no implied duties or responsibilities on the part of the
        Agent shall be read into this Agreement or any Transaction Document or
        shall otherwise exist.

                (b) The duties and responsibilities of the Agent under this
        Agreement and the other Transaction Documents shall be mechanical and
        administrative in nature, and the Agent shall not have a fiduciary
        relationship in respect of any Bank.

                (c) The Agent is and shall be solely the agent of the Banks. The
        Agent does not assume, and shall not at any time be deemed to have, any
        relationship of agency or trust with or for, or any other duty or
        responsibility to, any other Person (except only for its relationship as
        agent for, and its express duties and responsibilities to, the Banks as
        provided in this Agreement and the other Transaction Documents).

                (d) The Agent shall be under no obligation to take any action
        hereunder or under any other Transaction Document if the Agent believes
        in good faith that taking such action may conflict with any Law or any
        provision of this Agreement or any other Transaction Document, or may
        require the Agent to qualify to do business in any jurisdiction where it
        is not then so qualified.

        8.03. EXERCISE OF POWERS. The Agent shall take any action of the type
specified in this Agreement or any other Transaction Document as being within
the Agent's rights, powers or discretion in accordance with directions from the
Required Banks (or, to the extent this Agreement or such Transaction Document
expressly requires the direction or consent of some other Person or set of
Persons, then instead in accordance with the directions of such other Person or
set of Persons). In the absence of such directions, the Agent shall have the
authority (but under no circumstances shall be obligated), in its sole
discretion, to take any such action, except to the extent this Agreement or such
Transaction Document expressly requires the direction or consent of the Required
Banks (or some other Person or set of Persons), in which case the Agent shall
not take such action absent such direction or consent. Any action or inaction
pursuant to such direction, discretion or consent shall be binding on all the
Banks. The Agent shall not have any liability to any Person as a result of (x)
the Agent acting or refraining from acting in accordance with the directions of
the Required Banks (or other applicable Person or set of Persons), (y) the Agent
refraining from acting in the absence of instructions to act from the Required
Banks (or other applicable Person or set of Persons), whether or

                                       48
<PAGE>

not the Agent has discretionary power to take such action, or (z) the Agent
taking discretionary action it is authorized to take under this Section
(subject, in the case of this clause (z), to the provisions of Section 8.04(a)
hereof).

        8.04. GENERAL EXCULPATORY PROVISIONS. Notwithstanding anything to the
contrary elsewhere in this Agreement or any other Transaction Document:

        (a) The Agent shall not be liable for any action taken or omitted to be
taken by it under or in connection with this Agreement or any other Transaction
Document, unless caused by its own gross negligence or willful misconduct.

        (b) The Agent shall not be responsible for (i) the execution (other than
its own), delivery, effectiveness, enforceability, genuineness, validity or
adequacy of this Agreement or any other Transaction Document, (ii) any recital,
representation, warranty, document, certificate, report or statement in,
provided for in, or received under or in connection with, this Agreement or any
other Transaction Document which is made or issued by any Person other than the
Agent, (iii) any failure of any Credit Party or Bank to perform any of their
respective obligations under this Agreement or any other Transaction Document,
or (iv) the existence, validity, enforceability, perfection, recordation,
priority, adequacy or value, now or hereafter, of any Lien or other direct or
indirect security afforded or purported to be afforded by any of the Transaction
Documents or otherwise from time to time.

        (c) The Agent shall not be under any obligation to ascertain, inquire or
give any notice relating to (i) the performance or observance of any of the
terms or conditions of this Agreement or any other Transaction Document on the
part of any Credit Party, (ii) the business, operations, condition (financial or
otherwise) or prospects of any Credit Party or any other Person, or (iii) except
to the extent set forth in Section 8.05(f) hereof, the existence of any Event of
Default or Potential Default.

        (d) The Agent shall not be under any obligation, either initially or on
a continuing basis, to provide any Bank with any notices, reports or information
of any nature, whether in its possession presently or hereafter, except for such
notices, reports and other information expressly required by this Agreement or
any other Transaction Document to be furnished by the Agent to such Bank.

        8.05. ADMINISTRATION BY THE AGENT.

        (a) The Agent may rely upon any notice or other communication of any
nature (written or oral, including but not limited to telephone conversations,
whether or not such notice or other communication is made in a manner permitted
or required by this Agreement or any Transaction Document) purportedly made by
or on behalf of the proper party or parties, and the Agent shall not have any
duty to verify the identity or authority of any Person giving such notice or
other communication.

        (b) The Agent may consult with legal counsel (including, without
limitation, in-house counsel for the Agent or in-house or other counsel for any
Credit Party), independent public accountants and any other experts selected by
it from time to time, and the Agent shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts.

        (c) The Agent may conclusively rely upon the truth of the statements and
the correctness of the opinions expressed in any certificates or opinions
furnished to the Agent in accordance with the requirements of this Agreement or
any other Transaction Document. Whenever the Agent shall deem

                                       49
<PAGE>

it necessary or desirable that a matter be proved or established with respect to
any Credit Party or Bank, such matter may be established by a certificate of
such Credit Party or Bank, as the case may be, and the Agent may conclusively
rely upon such certificate (unless other evidence with respect to such matter is
specifically prescribed in this Agreement or another Transaction Document).

        (d) The Agent may fail or refuse to take any action unless it shall be
indemnified to its satisfaction from time to time against any and all amounts,
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature which may be imposed on,
incurred by or asserted against the Agent by reason of taking or continuing to
take any such action.

        (e) The Agent may perform any of its duties under this Agreement or any
other Transaction Document by or through agents or attorneys-in-fact. The Agent
shall not be responsible for the negligence or misconduct of any agents or
attorneys-in fact selected by it with reasonable care.

        (f) The Agent shall not be deemed to have any knowledge or notice of the
occurrence of any Event of Default or Potential Default unless the Agent has
received notice from a Bank or any Credit Party referring to this Agreement,
describing such Event of Default or Potential Default, and stating that such
notice is a "notice of default". If the Agent receives such a notice, the Agent
shall give prompt notice thereof to each Bank.

        8.06. BANK NOT RELYING ON AGENT OR OTHER BANKS. Each Bank acknowledges
as follows: (a) neither the Agent nor any other Bank has made any
representations or warranties to it, and no act taken hereafter by the Agent or
any other Bank shall be deemed to constitute any representation or warranty by
the Agent or such other Bank to it; (b) it has, independently and without
reliance upon the Agent or any other Bank, and based upon such documents and
information as it has deemed appropriate, made its own credit and legal analysis
and decision to enter into this Agreement and the other Transaction Documents;
and (c) it will, independently and without reliance upon the Agent or any other
Bank, and based upon such documents and information as it shall deem appropriate
at the time, make its own decisions to take or not take action under or in
connection with this Agreement and the other Transaction Documents.

        8.07. INDEMNIFICATION. Each Bank agrees to reimburse and indemnify the
Agent and its directors, officers, employees and agents (to the extent not
reimbursed by a Credit Party and without limitation of the obligations of the
Credit Parties to do so), ratably in accordance with their respective Letter of
Credit Participating Interests, from and against any and all amounts, losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements of any kind or nature (including,
without limitation, the reasonable fees and disbursements of counsel for the
Agent or such other Person in connection with any investigative, administrative
or judicial proceeding commenced or threatened, whether or not the Agent or such
other Person shall be designated a party thereto) that may at any time be
imposed on, incurred by or asserted against the Agent or such other Person as a
result of, or arising out of, or in any way related to or by reason of, this
Agreement, any other Transaction Document, any transaction from time to time
contemplated hereby or thereby, or any transaction to which a Letter of Credit
directly or indirectly relates, PROVIDED that no Bank shall be liable for any
portion of such amounts, losses, liabilities, claims, damages, expenses,
obligations, penalties, actions, judgments, suits, costs or disbursements to the
extent resulting from the gross negligence or willful misconduct of the Agent or
such other Person, as finally determined by a court of competent jurisdiction.
Payments under this Section shall be due and payable on demand, and to the
extent that any Bank fails to pay any such amount after a proper demand, such
amount shall bear interest for each day from the date of demand until paid
(before and after judgment) at a rate per

                                       50
<PAGE>

annum (calculated on the basis of a year of 360 days and actual days elapsed)
which for each day shall be equal to 2% over the interest rate per annum
announced by the Federal Reserve Bank of New York or otherwise determined by the
Agent to be applicable for such day to overnight federal funds transactions
arranged by federal funds brokers on the previous trading day.

        8.08. AGENT IN ITS INDIVIDUAL CAPACITY. With respect to its commitments
hereunder and the Obligations owing to it, the Agent shall have the same rights
and powers under this Agreement and each other Transaction Document as any other
Bank and may exercise the same as though it were not the Agent, and the terms
"Banks" and like terms shall include the Agent in its individual capacity as
such. The Agent and its affiliates may, without liability to account, make loans
to, accept deposits from, acquire debt or equity interests in, act as trustee
under indentures of, act as agent under other credit facilities for, and engage
in any other business with, any Credit Party and any stockholder, subsidiary or
affiliate of any Credit Party, as though the Agent were not the Agent hereunder.

        8.09. SUCCESSOR AGENT. The Agent may resign at any time by giving 10
days' prior written notice thereof to the Banks and the Account Parties. The
Agent may be removed by the Required Banks at any time by giving 10 days' prior
written notice thereof to the Agent, the other Banks and the Account Parties.
Upon any such resignation or removal, the Required Banks shall have the right to
appoint a successor Agent. If no successor Agent shall have been so appointed
and consented to, and shall have accepted such appointment, within 30 days after
such notice of resignation or removal, then the retiring Agent may, on behalf of
the Banks, appoint a successor Agent. Each successor Agent shall be a commercial
bank or trust company organized under the laws of the United States of America
or any State thereof and having a combined capital and surplus of at least
$1,000,000,000. Upon the acceptance by a successor Agent of its appointment as
Agent hereunder, such successor Agent shall thereupon succeed to and become
vested with all the properties, rights, powers, privileges and duties of the
former Agent, without further act, deed or conveyance. Upon the effective date
of resignation or removal of a retiring Agent, such Agent shall be discharged
from its duties under this Agreement and the other Transaction Documents, but
the provisions of this Agreement shall inure to its benefit as to any actions
taken or omitted by it while it was Agent under this Agreement. If and so long
as no successor Agent shall have been appointed, then any notice or other
communication required or permitted to be given by the Agent shall be
sufficiently given if given by the Required Banks, all notices or other
communications required or permitted to be given to the Agent shall be given to
each Bank, and all payments to be made to the Agent shall be made directly to
the Account Parties or Bank for whose account such payment is made.

        8.10. ADDITIONAL AGENTS. If the Agent shall from time to time deem it
necessary or advisable, for its own protection in the performance of its duties
hereunder or in the interest of the Banks, the Agent and the Account Parties
shall execute and deliver a supplemental agreement and all other instruments and
agreements necessary or advisable, in the opinion of the Agent, to constitute
another commercial bank or trust company, or one or more other Persons approved
by the Agent, to act as co-Agent or agent with such powers of the Agent as may
be provided in such supplemental agreement and to vest in such bank, trust
company or Person as such co-Agent or separate agent, as the case may be, any
properties, rights, powers, privileges and duties of the Agent under this
Agreement or any other Transaction Document.

        8.11. CALCULATIONS. The Agent shall not be liable for any calculation,
apportionment or distribution of payments made by it in good faith. If such
calculation, apportionment or distribution is subsequently determined to have
been made in error, the sole recourse of any Bank to whom payment was due but
not made shall be to recover from the other Banks any payment in excess of the
amount to

                                       51

the appropriate Account Party, to recover such amount from the appropriate
Account Party.

        8.12. AGENT'S FEE. Each Account Party agrees to pay to the Agent, for
its individual account, a nonrefundable Agent's fee in an amount and at such

                                  MISCELLANEOUS

        9.01. NO IMPLIED WAIVER ETC. No delay or failure of the Agent or any
Bank in exercising any right, power or privilege hereunder shall affect such
right, power or privilege; nor shall any single or partial exercise thereof or
any abandonment or discontinuance of steps to enforce such a right, power or
privilege preclude any further exercise thereof or of any other right, power or
privilege. The rights and remedies hereunder of the Agent and the Banks are
cumulative and not exclusive of any rights or remedies which, it or they would
otherwise have. Any amendment, waiver, permit, consent or approval of any kind
or character on the part of the Agent or a Bank of any breach or default under
this Agreement or any such waiver of any provision or condition of this
Agreement must be in writing and shall be effective only to the extent in such
writing specifically set forth.

        9.02. SET-OFF. In case any one or more of the Events of Default
described in Article VII hereof shall occur, each Bank shall have the right, in
addition to all other rights and remedies available to it, to set-off against
the unpaid balance of its interests in any Letter of Credit Reimbursement
Obligations any debt owing by such Bank to the applicable Credit Party,
including without limitation any funds in any deposit account maintained by such
Credit Party with such Bank, and such Bank shall have and there is hereby
created in favor of such Bank a security interest in all deposit accounts
maintained by such Credit Party with such Bank, subject to Liens permitted under
6.03(f). Any sums obtained by any Bank by way of counterclaim, set-off, banker's
lien or other lien for application upon any Letter of Credit Reimbursement
Obligation shall be shared pro rata with the other Banks. Nothing in this
Agreement shall be deemed any waiver or prohibition of any right of banker's
lien or set-off under applicable Law.

        9.03. SURVIVAL OF PROVISIONS. Each of the representations, warranties,
covenants and agreements of the Credit Parties contained herein or made in
writing in connection herewith shall survive the execution and delivery of this
Agreement, and the issuance of any Letter of Credit hereunder.

        9.04. EXPENSES AND FEES; INDEMNITY.

        (a) Each Account Party agrees to pay or cause to be paid and to save the
Agent and (in the case of clause (iii) below) each of the Banks harmless against
liability for the payment of all reasonable out-of-pocket costs and expenses
(including but not limited to reasonable fees and expenses of counsel, including
local counsel, auditors, and all other professional, accounting, evaluation and
consulting costs) incurred by the Agent or such Bank from time to time arising
from or relating to (i) the negotiation, preparation, execution, delivery,
administration and performance of this Agreement and the other Transaction
Documents, (ii) any requested amendments,

                                       52
<PAGE>

modifications, supplements, waivers or consents (whether or not ultimately
entered into or granted) to this Agreement or any Transaction Document, and
(iii) the enforcement or preservation of rights under this Agreement or any
Transaction Document (including but not limited to any such costs or expenses
arising from or relating to (A) collection or enforcement of any other amount
owing hereunder or thereunder by the Agent or any Bank and (B) any litigation,
proceeding, dispute, work-out, restructuring or rescheduling related in any way
to this Agreement or the Transaction Documents. Notwithstanding the foregoing,
an Account Party shall not be required to pay costs and expenses of a Bank (in
its capacity as such) which were incurred by such Bank in connection with any
litigation, proceeding or other dispute relating solely to a claim made against
such Bank by one or more of the other Banks. Each Account Party hereby agrees to
pay all stamp, document, transfer, recording, filing, registration, search,
sales and excise fees and taxes and all similar impositions now or hereafter
determined by the Agent or any Bank to be payable in connection with this
Agreement or any other Transaction Documents or any other documents, instruments
or transactions pursuant to or in connection herewith or therewith, and an
Account Party agrees to save the Agent and each Bank harmless from and against
any and all present or future claims, liabilities or losses with respect to or
resulting from any omission to pay or delay in paying any such fees.

        (b) Each Account Party hereby agrees to reimburse and indemnify the
Agent and each Bank (the "Indemnified Parties") from and against any and all
losses, liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements of any kind or nature whatsoever
(including, without limitation, the reasonable fees and disbursements of counsel
for the Indemnified Parties in connection with any investigative, administrative
or judicial proceeding commenced or threatened, whether or not such Indemnified
Party shall be designated a party thereto) that may at any time be imposed on,
asserted against or incurred by such Indemnified Party as a result of, or
arising out of, or in any way related to or by reason of, this Agreement or any
other Transaction Document, any transaction from time to time contemplated
hereby or thereby, or any transaction to which any Letter of Credit directly or
indirectly relates (and without in any way limiting the generality of the
foregoing, including any violation or breach of any Law by any Credit Party or
any exercise by the Agent or any Bank of any of its rights or remedies under
this Agreement or any other Transaction Document; any breach of any
representation or warranty, covenant or agreement of any Credit Party); but
excluding any such losses, liabilities, claims, damages, expenses, obligations,
penalties, actions, judgments, suits, costs or disbursements to the extent
resulting from the gross negligence or willful misconduct of such Indemnified
Party, as finally determined by a court of competent jurisdiction. If and to the
extent that the foregoing obligations of the Account Parties under this Section
9.04, or any other indemnification obligation of the Account Parties hereunder
or under any other Transaction Document, are unenforceable for any reason, the
Account Parties hereby agree to make the maximum contribution to the payment and
satisfaction of such obligations which is permissible under applicable Law.
Notwithstanding the foregoing, an Account Party shall not be required to pay
costs and expenses of a Bank (in its capacity as such) which were incurred by
such Bank in connection with any litigation, proceeding or other dispute
relating solely to a claim made against such Bank by one or more of the other
Banks.

        9.05. SEVERABILITY. In the event any one or more of the provisions
contained in this Agreement or in any other Transaction Document should be held
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby. The parties shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid

                                       53
<PAGE>

provisions the economic effect of which comes as close as possible to that of
the invalid, illegal or unenforceable provisions.

        9.06. HOLIDAYS. Unless otherwise specified herein, whenever any payment
or action to be made or taken hereunder shall be stated to be due on a Saturday,
Sunday or public holiday under the laws of the Commonwealth of Pennsylvania or
Bermuda, such payment or action shall be made or taken on the next succeeding
Business Day and such extension of time shall in such case be included in
computing interest, if any, in connection with such payment or action.

        9.07. NOTICES, ETC. Any notice or other communication in connection with
this Agreement shall be deemed to have been given or made when received by the
party to whom directed. All such notices and other communications shall be in

        9.08. FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED

OTHER TRANSACTION DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, OR ANY

VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY.

        9.13. SUCCESSORS AND ASSIGNS; PARTICIPATIONS; ASSIGNMENTS.

        (a) SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall be
binding upon and inure to the benefit of the Account Parties, the Banks, the
Agent, and their respective successors and assigns, except that no Credit Party
may assign or otherwise transfer any of its rights or duties under this
Agreement without the prior written consent of the Agent and all of the Banks,
and any purported assignment without such consent shall be void.

        (b) PARTICIPATIONS. Any Bank may, in the ordinary course of its
commercial banking business and in accordance with applicable Law, at any time
sell participations to one or more commercial banks or other Persons (each a
"Participant") in a portion of its rights and obligations under this Agreement
and the other Transaction Documents (including, without limitation, all or a
portion of its Letter of Credit Commitment and Letter of Credit Interests);
PROVIDED, that

                (i) any such participation sold to a Participant which is not a
        Bank, an affiliate of a Bank or a Federal Reserve Bank shall be made
        only with the consent (which in each case shall not be unreasonably
        withheld) of XL Capital and the Agent, unless an Event of Default has
        occurred and is continuing, in which case the consent of XL Capital
        shall not be required,

                (ii) any such Bank's obligations under this Agreement and the
        other Transaction Documents shall remain unchanged,

                (iii) such Bank shall remain solely responsible to the other
        parties hereto for the performance of such obligations,

                (iv) the parties hereto shall continue to deal solely and
        directly with such Bank in connection with such Bank's rights and

<PAGE>

                (v) such Participant shall be bound by the provisions of Section
        9.18 hereof, and the Bank selling such participation shall obtain from
        such Participant a written confirmation of its agreement to be so bound,

                (vi) no Participant (unless such Participant is an affiliate of
        such Bank, or is itself a Bank) shall be entitled to require such Bank
        to take or refrain from taking action under this Agreement or under any
        other Transaction Document, except that such Bank may agree with such
        Participant that such Bank will not, without such Participant's consent,
        take action of the type described in subsections (a), (b), (c), (d) or
        (e) of Section 9.14 hereof, and

                (vii) a Participant shall have the right to vote regarding
        amendments to this Agreement only in connection with amendments which
        effect changes in the amount of Letter of Credit Commitments, Letter of
        Credit Interests, fees payable hereunder and the Expiration Date.

Each Account Party agrees that any such Participant shall be entitled to the
benefits of Sections 2.09 and 9.04 with respect to its participation in the
Commitments and the Letters of Credit outstanding from time to time; PROVIDED,
that no such Participant shall be entitled to receive any greater amount
pursuant to such Sections than the transferor Bank would have been entitled to
receive in respect of the amount of the participation transferred to such
Participant had no such transfer occurred.

        (c) ASSIGNMENTS. Any Bank may, in the ordinary course of its commercial
banking business and in accordance with applicable Law, at any time assign all
or a portion of its rights and obligations under this Agreement and under any
Letter of Credit to which it is a party (if such Letter of Credit permits such
assignment or the beneficiary consents thereto) and under the other Transaction
Documents (including, without limitation, all or any portion of its Letter of
Credit Commitments and Letter of Credit Interests) to any Bank, any affiliate of
a Bank or to one or more additional commercial banks or other Persons (each a
"Purchasing Bank"); provided, that

                (i) any such assignment to a Purchasing Bank which is not a
        Bank, an affiliate of a Bank or a Federal Reserve Bank shall be made
        only with the consent (which in each case shall not be unreasonably
        withheld) of XL Capital and the Issuing Bank, unless an Event of Default
        has occurred and is continuing or exists, in which case the consent of
        XL Capital shall not be required,

                (ii) if a Bank makes such an assignment of less than all of its
        then remaining rights and obligations under this Agreement and the other
        Transaction Documents, such assignment shall be in a minimum aggregate
        principal amount of $10,000,000 of the Letter of Credit Commitments and
        Letter of Credit Interests then outstanding,

                (iii) each such assignment shall be of a constant, and not a
        varying, percentage of each Commitment of the transferor Bank and of all
        of the transferor Bank's rights and obligations under this Agreement and
        the other Transaction Documents, and

                (iv) each such assignment shall be made pursuant to a Transfer
        Supplement in substantially the form of EXHIBIT B to this Agreement,
        duly completed (a "Transfer Supplement").

                                       56
<PAGE>

                In order to effect any such assignment, the transferor Bank and
        the Purchasing Bank shall execute and deliver to the Agent a duly
        completed Transfer Supplement (including the consents required by clause
        (i) of the preceding sentence) with respect to such assignment, and a
        processing and recording fee of $2,500; and, upon receipt thereof, the
        Agent shall accept such Transfer Supplement; PROVIDED, HOWEVER, that no
        such processing and recording fee shall be due if such assignment is to
        an affiliate of a Bank or a Federal Reserve Bank . Upon receipt of the
        Purchase Price Receipt Notice pursuant to such Transfer Supplement, the
        Agent shall record such acceptance in the Register. Upon such execution,
        delivery, acceptance and recording, from and after the close of business
        at the Agent's Office on the Transfer Effective Date specified in such
        Transfer Supplement.

                (x) the Purchasing Bank shall be a party hereto and, to the
        extent provided in such Transfer Supplement, shall have the rights and
        obligations of a Bank hereunder, and

                (y) the transferor Bank thereunder shall be released from its
        obligations under this Agreement to the extent so transferred (and, in
        the case of an Transfer Supplement covering all or the remaining portion
        of a transferor Bank's rights and obligations under this Agreement, such
        transferor Bank shall cease to be a party to this Agreement) from and
        after the Transfer Effective Date.

        (d) REGISTER. The Agent shall maintain at its office a copy of each
Transfer Supplement delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Banks and the Letter of Credit
Commitment of, and the amount of the Letter of Credit Interests of, each Bank
from time to time. The entries in the Register shall be conclusive absent
manifest error and the Account Parties, the Agent and the Banks may treat each
person whose name is recorded in the Register as a Bank hereunder for all
purposes of the Agreement. The Register shall be available for inspection by any
Account Party or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

        (e) FINANCIAL AND OTHER INFORMATION. Each Credit Party authorizes the
Agent and each Bank to disclose to any Participant or Purchasing Bank (each, a
"transferee") and any prospective transferee any and all financial and other
information in such Person's possession concerning the Credit Parties and their
affiliates which has been or may be delivered to such Person by or on behalf of
the Credit Parties in connection with this Agreement or any other Transaction
Document or such Person's credit evaluation of the Credit Parties and their
affiliates. At the request of any Bank, a Credit Party, at such Credit Party's
expense, shall provide to each prospective transferee the conformed copies of
documents referred to in Section 4 of the form of Transfer Supplement.

        9.14. AMENDMENTS AND WAIVERS. Neither this Agreement nor any Transaction
Document may be amended, modified or supplemented except in accordance with the
provisions of this Section. The Agent and the Credit Parties may from time to
time amend, modify or supplement the provisions of this Agreement or any other
Transaction Document for the purpose of amending, adding to, or waiving any
provisions or changing in any manner the rights and duties of any Credit Party,
the Agent or any Bank. Any such amendment, modification or supplement made by
the Credit Parties and the Agent in accordance with the provisions of this
Section shall be binding upon the Credit Parties, each Bank and the Agent. The
Agent shall enter into such amendments, modifications or supplements from time
to time as directed by the Required Banks, and only as so directed, PROVIDED,
that no such amendment, modification or supplement may be made which will:

                                       57
<PAGE>

        (a) Increase the Letter of Credit Committed Amount of any Bank over the
amount thereof then in effect, or extend the Expiration Date, without the
written consent of each Commitment Bank affected thereby;

        (b) Reduce the amount of or postpone the date for payment of any
Commitment Fee or Letter of Credit Fee or reduce or postpone the date for
payment of any other fees, expenses, indemnities or amounts payable under any
Transaction Document, without the written consent of each Bank affected thereby;

        (c) Change the definition of "Required Banks" or amend this Section
9.14, without the written consent of all the Banks;

        (d) Amend or waive any of the provisions of Article VII hereof, or
impose additional duties upon the Agent or otherwise adversely affect the
rights, interests or obligations of the Agent, without the written consent of
the Agent;

        (e) Amend or waive any of the provisions of Article X or release any
Guarantor from its obligations hereunder without the written consent of all the
Banks; or

        (f) Amend the definition of Qualifying Securities or of Required
Qualifying Securities (as each such term is defined herein and in the Pledge
Agreement) or release all or (except in accordance with the terms of the Pledge
Agreement) any material part of the Collateral under the Pledge Agreement or
release XL Re, XL Europe and XL Investments from all of their respective
obligations as the Grantors thereunder, without the written consent of all of
the Banks;

and PROVIDED FURTHER, that Transfer Supplements may be entered into in the
manner provided in Section 9.13 hereof. Any such amendment, modification or
supplement must be in writing and shall be effective only to the extent set
forth in such writing. Any Event of Default or Potential Default waived or
consented to in any such amendment, modification or supplement shall be deemed
to be cured and not continuing to the extent and for the period set forth in
such waiver or consent, but no such waiver or consent shall extend to any other
or subsequent Event of Default or Potential Default or impair any right
consequent thereto. Implementation of a Future Collateral Allocation Transaction
(as defined in Section 8.01(b) hereof) shall require the consent of the Required
Banks, the Issuing Bank and the Agent, but shall not require the consent of all
of the Banks. Notwithstanding the foregoing, in connection with a Permitted
Intercompany Transfer (as defined in the Pledge Agreement), (x) the Pledge
Agreement may be amended to add an Additional Pledgor (as defined in the Pledge
Agreement) as a party thereto as contemplated by the Pledge Agreement, (y) the
Agent may sign on behalf of the Banks a new pledge agreement with an Additional
Pledgor as contemplated by the Pledge Agreement and (z) the Agent may sign on
behalf of the Banks a new custodian's acknowledgement with the Custodian and an
Additional Pledgor as contemplated by the Pledge Agreement, in each case without
the consent of the Required Banks.

        9.15. JUDGMENT CURRENCY. In the event of a judgment or order being
rendered by any court or tribunal for the payment of any amounts owing to the
Banks, the Agent or any of them under this Agreement or any other Transaction
Document or for the payment of damages in respect of any breach of this
Agreement or any other Transaction Document or under or in respect of a judgment
or order of another court or tribunal for the payment of such amounts or
damages, such judgment or order being expressed in a currency (the "Judgment
Currency") other than Dollars the party against whom the judgment or order is
made shall indemnify and hold the Banks and the Agent harmless against any
deficiency in terms of Dollars in the amounts received by the Banks or the
Agent, as the case may be,

                                       58
<PAGE>

arising or resulting from any variations as between (i) the exchange rate at
which Dollars are converted into the Judgment Currency for the purposes of such
judgment or order and (ii) the exchange rate at which each Bank or the Agent, as
the case may be, is able to purchase Dollars with the amount of the Judgment
Currency actually received by such Bank or the Agent, as the case may be, on the
date of such receipt. The indemnity in this section shall constitute a separate
and independent obligation from the other obligations of the Account Parties
hereunder and shall apply irrespective of any indulgence granted by the Banks.

        9.16. RECORDS. The amount of outstanding Letters of Credit, each Bank's
Letter of Credit Committed Amount and the accrued and unpaid Commitment Fees
shall at all times be ascertained from the records of the Agent, which shall be
conclusive absent manifest error.

        9.17 CONFIDENTIALITY. Each of the Agent and the Banks agree to keep
confidential any information relating to the Credit Parties received by it
pursuant to or in connection with this Agreement which is (a) information which
the Agent and the Banks reasonably expect that the applicable Credit Party would
want to keep confidential or (b) information which is clearly marked
"CONFIDENTIAL"; provided, however, that this Section 9.17 shall not be construed
to prevent the Agent or any Bank from disclosing such information (i) to any
affiliate that shall agree in writing for the benefit of the Credit Parties to
be bound by this obligation of confidentiality, (ii) upon the order of any court
or administrative agency of competent jurisdiction, (iii) upon the request or
demand of any regulatory agency or authority having jurisdiction over the Agent
or such Bank which request or demand has the force of Law or is made by a bank
regulatory agency, (iv) that has been publicly disclosed, other than from a
breach of this provision by the Agent or any Bank, (v) that has been obtained
from any person that is neither a party to this Agreement nor an affiliate of
any such party, but only to the extent that such Bank does not know or have
reason to know that such disclosure violates a confidentiality agreement between
such person and the applicable Credit Party (vi) in connection with the exercise
of any right or remedy hereunder or under any other Transaction Document, (vii)
as expressly contemplated by this Agreement or any other Transaction Document or
(viii) to any prospective purchaser of all or any part of the interest of any
Bank which shall agree in writing for the benefit of the Credit Parties to be
bound by the obligation of confidentiality in this Agreement or the other
Transaction Documents if such prospective purchaser is a financial institution
or has been consented to by the Account Parties, which consent will not be
withheld if such purchaser is not a competitor of any Account Party or an
affiliate of a competitor of any Account Party.

        9.18. SHARING OF COLLECTIONS. The Banks hereby agree among themselves
that if any Bank shall receive (by voluntary payment, realization upon security,
set-off or from any other source) any amount on account of any Obligation
contemplated by this Agreement or the other Transaction Documents to be made by
an Account Party pro rata to all Banks in greater proportion than any such
amount received by any other Bank, then the Bank receiving such proportionately
greater payment shall notify each other Bank and the Agent of such receipt, and
equitable adjustment will be made in the manner stated in this Section 9.18 so
that, in effect, all such excess amounts will be shared ratably among all of the
Banks. The Bank receiving such excess amount shall purchase (which it shall be
deemed to have done simultaneously upon the receipt of such excess amount) for
cash from the other Banks a participation in the applicable Obligations owed to
such other Banks in such amount as shall result in a ratable sharing by all
Banks of such excess amount (and to such extent the receiving Bank shall be a
Participant). If all or any portion of such excess amount is thereafter
recovered from the Bank making such purchase, such purchase shall be rescinded
and the purchase price restored to the extent of such recovery, together with
interest or other amounts, if any, required by Law to be paid by the Bank making
such purchase. The Account Parties hereby

                                       59
<PAGE>

consent to and confirm the foregoing arrangements. Each Participant shall be
bound by this Section 9.18 as fully as if it were a Bank hereunder."

        10.01. THE GUARANTEE. Each of the Guarantors hereby irrevocably,
unconditionally and absolutely guarantees as of the Effective Date to the Agent
and the Banks, and becomes surety for, the prompt payment of the Obligations of
the Account Parties (the "Guaranteed Obligations") in full when due (whether at
stated maturity, by acceleration, or otherwise) strictly in accordance with the
terms thereof. Each Guarantor hereby further agrees, as a primary obligor, that
if any of the Guaranteed Obligations are not paid in full when due (whether at
stated maturity, by acceleration, or otherwise and whether or not such payments
would not be permitted under any applicable bankruptcy or similar law), the
Guarantor will promptly pay the same, without any demand or notice whatsoever
(except as expressly provided herein), and that in the case of any extension of
time of payment or renewal of any of the Guaranteed Obligations, the same will
be promptly paid in full when due (whether at extended maturity, by acceleration
or otherwise) in accordance with the terms of such extension or renewal.

Notwithstanding any provision to the contrary contained herein or in any other
of the Transaction Documents, to the extent the obligations of any Guarantor
shall be adjudicated to be invalid or unenforceable for any reason (including,
without limitation, because of any applicable law, including the insolvency
laws, relating to fraudulent conveyances or transfers) then the obligations of
such Guarantor hereunder automatically shall be limited to the maximum amount
that is permissible under applicable law.

        10.02. OBLIGATIONS UNCONDITIONAL. The obligations of each Guarantor
under this Article are irrevocable, absolute and unconditional (to the fullest
extent permitted by applicable law), irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Transaction Documents, or
any other agreement or instrument referred to therein, or any substitution,
release or exchange of any other guarantee of or security for any of the
Guaranteed Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Article that the obligations of each Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.
Each Guarantor agrees that such Guarantor shall have no right of subrogation,
indemnity, reimbursement or contribution against any Account Party, for amounts
paid under this Article X until such time as the Banks have been paid in full,
no Letter of Credit is outstanding, the Letter of Credit Commitments under this
Agreement have been terminated and no Person or Governmental Authority shall
have any right to request any return or reimbursement of funds from any Bank in
connection with monies received under the Transaction Documents. Without
limiting the generality of the foregoing, it is agreed that, to the fullest
extent permitted by applicable law, the occurrence of any one or more of the
following shall not alter or impair the liability of any Guarantor hereunder
which shall remain irrevocable, absolute and unconditional as described above:

                                       60
<PAGE>

                (i) at any time or from time to time, without notice to the
        Guarantors, the time for any performance of or compliance with any of
        the Guaranteed Obligations shall be extended, or such performance or
        compliance shall be waived;

                (ii) any of the acts mentioned in any of the provisions of any
        of the Transaction Documents, or any other agreement or instrument
        referred to in the Transaction Documents shall be done or omitted;

                (iii) the maturity of any of the Guaranteed Obligations shall be
        accelerated, or any of the Guaranteed Obligations shall be modified,
        supplemented or amended in any respect, or any right under any of the
        Transaction Documents, or any other agreement or instrument referred to
        in the Transaction Documents shall be waived or any other guarantee of
        any of the Guaranteed Obligations or any security therefor shall be
        released or exchanged in whole or in part or otherwise dealt with;

                (iv) any Lien granted to, or in favor of, the Agent or any Bank
        as security for any of the Guaranteed Obligations shall be void or
        voidable, or shall fail to attach or be perfected or the Agent or any
        Bank shall fail to realize on any collateral security; or

                (v) any of the Guaranteed Obligations shall be determined to be
        void or voidable (including, without limitation, for the benefit of any
        creditor of any Guarantor) or shall be subordinated to the claims of any
        Person (including, without limitation, any creditor of any Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever (except notices expressly required hereunder), and any requirement
that the Agents, the Banks or any of them exhaust any right, power or remedy or
proceed against any Person under any of the Transaction Documents, or any other
agreement or instrument referred to in the Transaction Documents, or against any
other Person under any other guarantee of, or security for, any of the
Guaranteed Obligations. This is a guarantee of payment and not merely of
collection.

        10.03. REINSTATEMENT. The obligations of the Guarantors under this
Article shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of any Person in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy, receivership, or reorganization or otherwise, and each Guarantor
agrees that it will indemnify the Agent and the Banks on demand for all
reasonable out-of-pocket costs and expenses (including, without limitation,
reasonable fees and expenses of counsel) incurred by the Agent or any Bank in
connection with such rescission or restoration, including any such reasonable
costs and expenses incurred in defending against any claim alleging that such
payment constituted a preference, fraudulent transfer or similar payment under
any bankruptcy, insolvency, receivership, reorganization or similar law.

        10.04. REMEDIES. Each Guarantor agrees that, to the fullest extent
permitted by applicable law, as between such Guarantor, on the one hand, and the
Agent and the Banks, on the other hand, the Guaranteed Obligations may be
declared to be forthwith due and payable as provided in Section 7.01 hereof (and
shall be deemed to have become automatically due and payable in the
circumstances provided in said Section 7.01) for purposes of Section 10.01
hereof notwithstanding any stay, injunction or other prohibition preventing such
declaration (or preventing the Guaranteed

                                       61
<PAGE>

Obligations from becoming automatically due and payable) as to any other Person
and that, in the event of such declaration (or Guaranteed Obligations being
deemed to have become automatically due and payable), the Guaranteed Obligations
(whether or not due and payable by any other Person) shall forthwith become due
and payable by such Guarantor for purposes of said Section 10.01.

        10.05. CONTINUING GUARANTEE. The guarantee in this Article is a
continuing guarantee, and shall apply to all of the Guaranteed Obligations
whenever arising.

        10.06. NO RESTRICTIONS. Except for restrictions under the Transaction
Documents, no Guarantor shall be or become subject to any restriction of any
nature (whether arising by operation of Law, by agreement, by its articles of
incorporation, by-laws or other constituent documents of such Guarantor, or
otherwise) on the right of such Guarantor from time to time to (x) pay any
indebtedness, obligations or liabilities from time to time owed to any Account
Party, (y) make loans or advances to any Account Party, or (z) transfer any of
its properties or assets to any Account Party.

                                PLEDGE AGREEMENT

              THIS PLEDGE AGREEMENT (this "Agreement"), dated as of December 18,
2001, made by XL Investments Ltd, a company organized under the laws of Bermuda
("XL Investments"), XL Re Ltd, a company organized under the laws of Bermuda
("XL Re"), XL Insurance (Bermuda) Ltd, a company organized under the laws of
Bermuda ("XL Insurance") and XL Europe Ltd, a company organized under the laws
of Ireland ("XL Europe", XL Investments, XL Re and XL Insurance and XL Europe
being referred to collectively herein as the "Grantors" and individually as a
"Grantor" and XL Europe, XL Investments and XL Insurance being collectively
referred to herein as the "Guarantors") in favor of Citibank, N.A. (the "Bank").

                                    RECITALS:

              A. XL Re has entered into (i) a Master Agreement--London Market
Letter of Credit Scheme, dated as of October 21, 1996 and (ii) an Insurance
Letters of Credit--Master Agreement, dated as of May 19, 1993 (each as amended
from time to time, the "Reimbursement Agreements") in favor of the Bank pursuant
to which XL Re has agreed to, among other things, reimburse the Bank in
connection with the issuance by the Bank from time to time of letters of credit
for its account (the "Letters of Credit"). Each of XL Investments, XL Europe and
XL Insurance is an affiliate of XL Re. XL Re is the account party for the
account of which Letters of Credit may be issued on behalf of any of the
Grantors. Accordingly, each Grantor will derive substantial direct and indirect
benefit from the issuance of Letters of Credit and the transactions contemplated
by the Reimbursement Agreements.

              B. Each Guarantor shall execute, on even date herewith, a
guarantee agreement (the "Guarantee Agreement"), pursuant to which the
Guarantors guarantee, jointly and severally, the payment in full of the
obligations of XL Re under the Reimbursement Agreements.

              C. In order to (i) provide collateral security for the Letters of
Credit and the obligations under the Guarantee Agreement, and to induce the Bank
to extend credit under the Reimbursement Agreements and (ii) replace and
terminate the pledge of existing collateral by XL Re under the Security
Agreement (Form 15) dated August 7, 1998 (the "Security Agreement"), the
Grantors wish to execute and deliver this Agreement.

              D. Each Grantor acknowledges that the Bank will rely on this
Agreement in issuing Letters of Credit. Each Grantor further acknowledges that
it has, independently and without reliance upon the Bank or any representation
by or other information from the Bank, made its own credit analysis and decision
to enter into this Agreement.

              NOW, THEREFORE, in consideration of the foregoing and for other
good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, and intending to be legally bound, the Grantors hereby agree as
follows:

              (b) CERTAIN CROSS-REFERENCES. The following terms are defined in
this Agreement in the Section or other place indicated: "Collateral" in Section
2.1; "Grantor", "Grantors" and "Guarantors" in the Preamble; "notices" in
Section 6.3; and "Reimbursement Agreements" in the Recitals.

              1.2. UCC DEFINITIONS. Unless otherwise defined herein, terms
defined in Articles 8 or 9 of the UCC shall have the same meanings in this
Agreement.

                                   ARTICLE II
                                  THE SECURITY

              2.1. GRANT OF SECURITY. (a) As security for the full and timely
payment and performance of the Secured Obligations, each Grantor hereby assigns
and pledges to the Bank, and grants to the Bank, a security interest in, all
right, title and interest of such Grantor in, to and under the following,
whether now or hereafter existing or acquired (the "Collateral"):

              (i) the Designated Account with respect to such Grantor and each
       security entitlement (as such term is defined in Section 8-102(a)(17) of
       the UCC) from time to time credited to such Designated Account and all
       financial assets (as such term is defined in Section 8-102(a)(9) of the
       UCC) from time to time deposited therein;

              (ii) all claims and rights of whatever nature which such Grantor
       may now have or hereafter acquire against any third party(ies) in respect
       of any of the Collateral described in this Section 2.1(a) (including any
       claims or rights in respect of any security entitlements credited to an
       account of the Custodian maintained at The Depository Trust Company or
       any other clearing corporation) or any other securities intermediary (as
       such terms are defined in Section 8-102(a) of the UCC);

              (iii) all rights which such Grantor may now have or hereafter
       acquire against the Custodian in respect of its holding and managing all
       or any part of the Collateral; and

              (iv) all proceeds (as such term is defined in Section 9-102(a) of
       the UCC) of any of the foregoing.

              (b) Concurrently with the execution of this Agreement, (i) each of
the Grantors will execute and deliver or cause to be delivered to the Bank a
Control and Consent Acknowledgment and Agreement Concerning Designated Accounts
for each Designated Account (collectively referred to herein as the "Custodian's
Acknowledgment") in the form attached as Exhibit A hereto and (ii) the Bank
hereby notifies XL Re that, simultaneously with the execution and delivery of
the Custodian's Acknowledgment and this Agreement and the grant of the security
interest hereunder, the security interest granted to the Bank pursuant to the
Security Agreement is terminated. The Custodian's Acknowledgment shall not be
amended, modified, revoked or withdrawn without the prior written consent of the
Bank.

              (c) Each Grantor acknowledges that the Custodian is a securities
intermediary (as such term is defined in Section 8-102(a) of the UCC) for such
Grantor; each Grantor agrees with the Bank that notwithstanding any provision of
this Agreement or any other circumstance, the Bank shall have at all times
control (as defined in Section 8-106 of the UCC) of each Designated Account and
the Collateral, as confirmed in the Custodian's Acknowledgment, and shall be
authorized to direct the Custodian to comply with, and the Custodian shall
comply with, entitlement orders (as such term is defined in Section 8-102(a) of
the UCC) originated by the Bank with respect to the Collateral without further
consent of any Grantor or any Investment Manager or any other person acting or
purporting to act for such Grantor. The

                                       4
<PAGE>

Bank agrees that such entitlement orders referred to in the first sentence of
this Section 2.1(c) will be issued by the Bank to the Custodian in respect of
the Collateral only (i) in connection with the Bank's exercise of remedies upon
the occurrence and continuation of an Event of Default or (ii) to the extent
necessary to prevent the withdrawal of Collateral from a Designated Account or
release of Collateral from the Lien of this Agreement if such withdrawal or
release would cause noncompliance with, or result in noncompliance with, the
Collateral Value Requirement.

              (d) Each Grantor shall deliver, from time to time, to the Bank
(with a copy to the Custodian) a Pledge Supplement setting forth each additional
Designated Account, if any. Each Pledge Supplement, upon its delivery to the
Bank, shall be deemed to be incorporated in this Pledge Agreement. Any Pledge
Supplement delivered under this Agreement may be delivered by telecopier and
will be effective when so delivered, it being the intention of the parties that
an "ink" copy thereof will be sent (and the Grantors agree that they will send
such "ink" copy) promptly thereafter by regular mail or overnight courier.

              2.2. COLLATERAL VALUE, ETC. (a) The Grantors shall maintain
Required Qualifying Securities at all times as security entitlements in the
Designated Accounts (the "Collateral Value Requirement"). The preceding sentence
shall not preclude any Grantor from maintaining in the Designated Accounts
Qualifying Securities or other securities or assets in excess of the Required
Qualifying Securities. Each Grantor agrees that only Qualifying Securities may
be counted towards the Collateral Value Requirement. "Qualifying Securities"
means securities in a Designated Account which are not subject to any security
interest or lien in favor of any person other than the security interest of the
Bank under this Agreement and the Custodian's Acknowledgment and which consist
of: (i) direct claims (including securities, loans and leases) on, and the
portions of claims that are directly and unconditionally guaranteed by, the
central government of any OECD country or any U.S. Government Agency, as such
terms are used in Appendix A, Section III(C), Category I to Regulation H, as
promulgated by the Board of Governors of the Federal Reserve System; and (ii)
claims on, and the portions of claims that are guaranteed by, U. S.
Government-sponsored agencies and claims on, and the portions of claims
guaranteed by, certain multilateral lending institutions in which the U. S.
government is a shareholder or contributing member or shares of money market
mutual funds investing solely in U.S. Government Securities, as such terms are
used in Appendix A, Section III(C), Category II to such Regulation H; provided,
however, that those securities or obligations referred to in clauses (i) and
(ii) above shall not be counted towards the Collateral Value Requirement unless
such securities or obligations have a zero percent risk capital weighting under
such Regulation H, as amended from time to time. If at any time the market value
of the Qualifying Securities is less than the Collateral Value Requirement, the
Grantors shall, within two Business Days of such occurrence, deliver to one or
more Designated Accounts Qualifying Securities sufficient to satisfy the
Collateral Value Requirement.

              (b) In determining compliance by the Grantors with the Collateral
Value Requirement, the Bank may use any commercially reasonable valuation or
classification method determined by the Bank to be appropriate.

              2.3. SUBSTITUTION AND WITHDRAWAL, ETC. (a) So long as no Event of
Default has occurred and is continuing, and the market value of the Qualifying
Securities satisfies the Collateral Value Requirement, any Grantor (other than
XL Re in the case of clause (v) below) may:

              (i) substitute new Collateral for any existing Collateral,
       PROVIDED that, after giving effect to any such substitution, any
       substituted Collateral (together with other Collateral), satisfies the
       Collateral Value Requirement and the substituted Collateral is
       transferred to, or already maintained in, Designated Accounts;

              (ii) to the extent not inconsistent with the other provisions of
       this Agreement, trade, sell, exchange, lend or transfer from a Designated
       Account any Collateral so long as the Grantors contemporaneously and
       continually provide the Bank with such new or replacement Collateral as
       may be necessary to satisfy the Collateral Value Requirement;

              (iii) require the Bank to cause partial termination of the pledge
       of Collateral to the extent that sufficient Collateral remains after
       effecting such termination to satisfy the Collateral

                                       5
<PAGE>

       Value Requirement (such termination to be accomplished by execution and
       delivery of a termination agreement signed on behalf of the applicable
       Grantor and the Bank);

              (iv) subject at all times to compliance with the Collateral Value
       Requirement, receive and retain, free of all right, title and interest of
       the Bank, all interest and dividend payments made in respect of the
       Collateral and exercise any voting rights with respect thereto; and

              (v) subject at all times to compliance with the Collateral Value
       Requirement, by not less than three days' written notice to the Bank,
       remove a securities account from the category of Designated Accounts,
       whereupon any financial assets in such securities account shall no longer
       be subject to the Lien of this Agreement.

              (b) Whenever a Grantor substitutes new Collateral for existing
Collateral (such existing Collateral hereinafter referred to as "Replaced
Collateral") or causes the sale, exchange or transfer of, or causes the
termination of the pledge of, Collateral, in each case pursuant to and in
compliance with the foregoing provisions of Section 2.3(a) hereof, the Bank
shall be deemed to have released all right, title or interest in or to such
Replaced Collateral and such sold, exchanged, transferred or terminated
Collateral (and the proceeds thereof) arising hereunder. The sale, exchange or
transfer of Collateral in accordance with this Section 2.3(b) shall occur upon
the consummation of the sale or other transfer of ownership of such Collateral
by a Grantor to any third party or the consummation of a transfer of Collateral
from a Designated Account to another securities account maintained for such
Grantor.

              (c) Upon payment and satisfaction in full of the Secured
Obligations and termination of the Reimbursement Agreements, the Bank shall
promptly release to the Grantors all of the Bank's right, title and interest in
or to the Collateral to the extent arising under or pursuant to this Agreement.

              2.4. DELIVERY OF PROPERTY. In the event that a Grantor receives
any new securities, instruments, documents or other property by reason of
ownership of the Collateral (other than payments of a kind described in Section
2.3(a)(iv)), such Grantor shall promptly deliver all such property to the
Custodian, to be held by the Custodian in the Designated Accounts of such
Grantor as part of the Collateral. Promptly upon receipt thereof, each Grantor
agrees to deliver to the Bank all documents evidencing such property, together
with appropriate bond, stock or other powers duly executed by such Grantor.

              2.5. INVESTMENT RISK AND TAXES. As between the Bank and the
Grantors, the Grantors shall bear the investment risk with respect to the
Collateral, and the risk of loss of, damage to, or the destruction of the
Collateral, whether in possession of, or maintained as a security entitlement
by, or subject to the control of, the Bank, the Custodian, a Grantor or another
party, PROVIDED, HOWEVER, that nothing contained in this Section 2.5 shall
release or relieve the Custodian of its duties and obligations to Grantors or
any other party under the Custody Agreement or applicable law. Further, the
Grantors shall promptly pay all taxes, fees and charges of whatever kind or
nature with respect to the Collateral, all other taxes payable by any Grantor
which, if unpaid, could become a charge against the Collateral, and any stamp
duty or tax payable with respect to this Agreement. If the Grantors do not make
such payments, then the Bank may (but is in no way obligated to) pay such
amounts for the account of the applicable Grantor and any such amounts paid will
be added to the amount of the Secured Obligations.

              2.6. CONTINUING AGREEMENT. This Agreement creates a continuing
security interest in the Collateral and shall continue in full force and effect
until all Secured Obligations have been paid in cash and performed in full and
all Letters of Credit have terminated, subject in any event to reinstatement in
accordance with Section 2.9. Without limiting the generality of the foregoing,
each Grantor hereby irrevocably waives any right to terminate or revoke this
Agreement. Upon the payment in cash and performance in full of all Secured
Obligations and termination of all Letters of Credit, the security interest
granted hereby shall terminate and all rights to the Collateral shall revert to
the applicable Grantor. Upon any such termination, the Bank will, at the
Grantors' request and expense, return to the applicable Grantor, without any
representations, warranties or recourse of any kind whatsoever, such of the
Collateral as then may be held by the Bank hereunder, and execute and deliver to
the applicable Grantor such documents as the such Grantor may reasonably request
to evidence such termination.

              2.7. RIGHTS AND INTERESTS OF BANK ABSOLUTE. The obligations of
each Grantor under this Agreement are independent of the Secured Obligations,
and a separate action or actions may be brought and prosecuted against any
Grantor regardless of whether action is brought against any other Grantor or any
other Person or whether any other Grantor or any other Person is joined in any
such action or actions. The security interest granted hereby shall secure
payment and performance of the Secured Obligations strictly in accordance with
the terms of hereof, regardless of any law, regulation or order now or hereafter
in effect in any jurisdiction affecting the Secured Obligations (or the rights
of the Bank or any other Person with respect thereto). The security interest of
the Bank hereunder shall be absolute, unconditional and irrevocable and all
other rights and interests of the Bank hereunder, and all obligations of each
Grantor hereunder, shall be absolute and irrevocable, irrespective of any of the
following:

              (a) any lack of legality, validity, enforceability, allowability
       (in a bankruptcy, insolvency, reorganization, dissolution or similar
       proceeding, or otherwise), or any avoidance or subordination, in whole or
       in part, of any of the Secured Obligations;

              (b) any change in the amount, nature, time, place or manner of
       payment or performance of, or in any other term of, any of the Secured
       Obligations (specifically including any increase in the Secured
       Obligations, whether resulting from the extension of additional credit or
       otherwise);

              (c) any taking, exchange, release, impairment or nonperfection of
       any Collateral, or any taking, release, impairment or amendment or waiver
       of or consent to departure from any guaranty or other direct or indirect
       security for any of the Secured Obligations (it being understood that a
       release of Collateral in accordance with the terms of this Agreement is
       not rendered ineffective by reason of this Section 2.7(c));

              (d) any manner of application of Collateral or other direct or
       indirect security for any of the Secured Obligations, or proceeds
       thereof, to any of the Secured Obligations, or any manner of sale or
       other disposition of any Collateral for any of the Secured Obligations or
       any other assets of any Grantor;

              (e) any impairment by the Bank or any other Person of any recourse
       of any Grantor against the Bank or any other Person, or any other
       impairment by the Bank or any other Person of the suretyship status of
       either Grantor;

              (f) any bankruptcy, insolvency, reorganization, dissolution or
       similar proceeding with respect to, or any change, restructuring or
       termination of the corporate structure or existence of, any Grantor or
       any other Person;

              (g) any failure of the Bank or any other Person to disclose to any
       Grantor any information pertaining to the business, operations, condition
       (financial or otherwise) or prospects of the other Grantors or any other
       Person, or to give any other notice, disclosure or demand; or

              (h) any other event or circumstance (including any right of set
       off, defense of failure of consideration, breach of representation or
       warranty, statute of frauds, bankruptcy, lack of capacity, statute of
       limitations, release, accord and satisfaction or usury, and excluding
       only the defense of full, strict and indefeasible payment and
       performance) that might otherwise constitute a defense available to, a
       discharge of, or a limitation on the obligations of, any Grantor or a
       guarantor or surety.

              2.8. WAIVERS, ETC. Each Grantor hereby irrevocably waives any
defense to or limitation on its obligations under this Agreement arising out of
or based upon any matter referred to in Section 2.7 and, without limiting the
generality of the foregoing, any requirement of promptness, diligence or notice
of acceptance, any other notice, disclosure or demand with respect to any of the
Secured Obligations and this Agreement, any requirement of acceptance hereof,
reliance hereon or knowledge hereof by the Bank, and any requirement that the
Bank protect, secure, perfect or insure any lien or any property subject thereto
or exhaust any right or take any action against any other Grantor or any other
Person or any direct or indirect security for any of the Secured Obligations.

                                       7
<PAGE>

              2.9. REINSTATEMENT. This Agreement shall continue to be effective,
or be automatically reinstated, as the case may be, if at any time payment of
any of the Secured Obligations is avoided, rescinded or must otherwise be
returned by the Bank for any reason, all as though such payment had not been
made.

              2.10. NO STAY. Without limiting the generality of any other
provision of this Agreement, if any acceleration of the time for payment or
performance of any Secured Obligation, or any condition to any such
acceleration, shall at any time be stayed, enjoined or prevented for any reason
(including stay or injunction resulting from the pendency against any Grantor or
any other Person of a bankruptcy, insolvency, reorganization, dissolution or
similar proceeding), each Grantor agrees that, for purposes of this Agreement
and its obligations hereunder, at the option of the Bank such Secured Obligation
shall be deemed to have been accelerated and such condition to acceleration
shall be deemed to have been met.

              2.11. SUBROGATION, ETC. Any rights which any Grantor may have or
acquire by way of subrogation, reimbursement, restitution, exoneration,
contribution or indemnity, and any similar rights (whether arising by operation
of law, by agreement or otherwise), against any other Grantor or any other
Person, arising from the existence, payment, performance or enforcement of any
of the obligations of any Grantor under or in connection with this Agreement,
shall be subordinate in right of payment to the Secured Obligations, and such
Grantor shall not exercise any such rights until all Secured Obligations have
been paid in cash in full and all Letters of Credit shall have terminated. If,
notwithstanding the foregoing, any amount shall be received by any Grantor on
account of any such rights at any time prior to the time at which all Secured
Obligations shall have been paid in cash and performed in full and all Letters
of Credit shall have terminated, such amount shall be held by such Grantor in
trust for the benefit of the Bank, segregated from other funds held by such
Grantor, and shall be forthwith delivered to the Bank in the exact form received
by such Grantor (with any necessary endorsement), to be held as additional
Collateral. The forgoing will not, so long as no Event of Default has occurred
and is continuing, preclude any Grantor from receiving and retaining amounts
paid to it by a Person pursuant to a separate agreement between such Grantor and
such Person, which separate agreement provides to such Grantor no subrogation
rights under any document referred to herein.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

              Each Grantor hereby represents and warrants to the Bank as
follows:

              3.1. TITLE. Such Grantor is the legal and beneficial owner of the
Collateral (other than the Collateral of which any other Grantor is the legal
and beneficial owner), free and clear of any lien, security interest, option or
other charge or encumbrance, except for the security interest under this
Agreement in favor of the Bank securing the Secured Obligations and the
Custodian's right of set-off described in Section 4 of the Custodian's
Acknowledgment. No effective financing statement or other item similar in
effect, and no control agreement, in each case covering any Collateral is or
will be on file in any recording office or otherwise in effect, except such as
may be filed or made in favor of the Bank relating to this Agreement.

              3.2. VALIDITY, PERFECTION AND PRIORITY. This Agreement creates a
valid security interest in the Collateral in favor of the Bank securing the
Secured Obligations, which security interest has been duly perfected and is, and
will be, prior to all other liens, security interests, options or other charges
or encumbrances subject, however, to the Custodian's right of set-off described
in Section 4 of the Custodian's Acknowledgment. Except for the filing of this
Agreement with the Registrar of Companies in Bermuda and with the Irish
Registrar of Companies, no filing or other action is or will be necessary or
desirable to perfect or protect such security interest in favor of the Bank.

              3.3. GOVERNMENTAL APPROVALS AND FILINGS. Other than the filing of
this Agreement with the Registrar of Companies in Bermuda and with the Irish
Registrar of Companies, no authorization, approval or other action by, and no
notice to or filing with, any governmental authority or regulatory body is or
will be necessary (a) for the grant by such Grantor of the security interest in
the Collateral

                                       8
<PAGE>

hereunder or for the execution, delivery or performance of this Agreement by
such Grantor, (b) to ensure the validity, perfection or priority of the security
interest in the Collateral granted hereunder, or (c) for the exercise by the
Bank of any of its rights or remedies hereunder, except as may be required in
connection with a disposition of Collateral constituting securities by laws
affecting the offering and sale of securities generally.

              3.4. POWERS; ENFORCEABILITY; ETC. Such Grantor has, and will at
all times have, the necessary power to enable it to execute and deliver this
Agreement and perform the obligations expressed to be assumed by it under this
Agreement and its execution, delivery and performance of this Agreement do not
violate its charter or by-laws or any applicable law or regulation or any
contract or agreement to which it is a party. This Agreement constitutes the
legal, valid and binding obligation of such Grantor, enforceable in accordance
with its terms, except that (A) the enforceability thereof may be subject to
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
other similar laws now or hereafter in effect relating to or affecting
creditors' rights or remedies generally and (B) the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
equitable defenses and the discretion of the court before which any proceeding
therefor may be brought.

              3.5. NAMES, ETC. During the one year period ending on the date
hereof, no Grantor nor any of its direct or indirect predecessors by merger,
consolidation or other corporate reorganization is or has been known by or used
any corporate or fictitious name or trade name (other than the corporate name of
such Grantor as of the date hereof and other than, in the case of XL
Investments, the name "X.L. Investments Ltd.", other than, in the case of XL
Europe the name "XL Europe" and "X.L. Europe Insurance", other than, in the case
of XL Insurance, the name "XL Insurance Ltd" and other than, in the case of XL
Re, the names "X.L. Mid Ocean Reinsurance Company Ltd" and the name "X.L. Global
Reinsurance Company, Ltd."), nor has such Grantor or any such predecessor been
the subject of any merger, consolidation or other corporate reorganization, nor
has such Grantor or any such predecessor otherwise changed its name (except as
aforesaid), identity or corporate structure.

              3.6. MARGIN STOCK. None of the Collateral constitutes "margin
stock," as that term is used in Regulations T, U or X of the Board of Governors
of the Federal Reserve System, as amended from time to time.

                                   ARTICLE IV
                                    COVENANTS

              4.1. BOOKS AND RECORDS. Each Grantor shall, and shall cause the
Custodian to (a) keep complete and accurate books and records concerning the
Collateral and, at the request of the Bank from time to time, permit the Bank or
its representatives to inspect and copy such books and records, (b) at the
request of the Bank from time to time, permit the Bank or its representatives to
inspect any Collateral not in the possession of the Bank, and (c) furnish to the
Bank such information and reports in connection with the Collateral at such
times and in such form as the Bank may reasonably request. The Bank shall have
the right to examine and verify the Collateral from time to time, and such
Grantor shall, and shall cause the Custodian to, cooperate with the Bank in such
examination.

              4.2. TRANSFERS AND OTHER LIENS.

              (a) TRANSFERS. No Grantor shall sell, assign, transfer or
otherwise dispose of any Collateral (voluntarily or involuntarily, by operation
of law or otherwise), except as permitted by Section 2.3 hereof.

              (b) OTHER LIENS. No Grantor shall create or permit to exist any
lien, security interest, option or other charge or encumbrance on any Collateral
(voluntarily or involuntarily, by operation of law or otherwise), except for the
security interest under this Agreement in favor of the Bank securing the Secured
Obligations and the Custodian's right of set-off described in Section 4 of the
Custodian's Acknowledgment.

<PAGE>

              4.3. CHANGE IN NAME, OFFICE, ETC. Each Grantor shall (a) not,
without at least 30 days prior written notice to the Bank, have, use or be known
by any corporate or fictitious name or trade name (other than its corporate name
as of the date hereof), nor be the subject of any merger, consolidation or other
corporate reorganization, nor otherwise change its name, identity or corporate
structure, (b) give 30 days notice to the Bank of any change in its chief
executive office (which on the date hereof is with respect to XL Europe, La
Touche House, International Financial Services Centre, Dublin 1, Republic of
Ireland, and, with respect to XL Re, XL Insurance and XL Investments, XL House,
One Bermudiana Road, Hamilton HM11 Bermuda) and the offices (whether maintained
by such Grantor or otherwise) where books and records relating to the Collateral
are kept (which on the date hereof are such Grantor's office at the aforesaid
address and the office of the Custodian at One Mellon Bank Center, Pittsburgh,
PA 15258) and (c) with respect to XL Investments, XL Insurance and XL Re,
maintain its jurisdiction of incorporation and its chief executive office in
Bermuda and with respect to XL Europe, maintain its jurisdiction of
incorporation and its chief executive office in Ireland.

              4.4. CERTAIN COVENANTS.

              (a) VOTING RIGHTS.

              (i) GENERAL. Subject to Section 4.4(a)(ii), each Grantor shall be
entitled to exercise all voting and other consensual rights pertaining to the
Collateral; provided, that no Grantor shall exercise or refrain from exercising
any such right if such action would (A) conflict with any provision of this
Agreement, or (B) impair the value of any Collateral or impair the interest or
rights of any Grantor or the Bank.

              (ii) CERTAIN RIGHTS OF BANK. If an Event of Default has occurred
and is continuing, the Bank may from time to time give notice to the Grantors
revoking in whole or in part the rights of the Grantors under Section 4.4(a)(i).
If and to the extent such notice has been given, all voting and other consensual
rights pertaining to the Collateral shall thereupon be vested in the Bank, who
shall thereafter have the sole right to exercise or refrain from exercising such
rights.

              (iii) PROXIES, ETC. The Bank shall, if necessary, execute and
deliver to the Grantors such proxies and other instruments as the Grantors may
reasonably request for the purpose of enabling each Grantor to exercise the
voting and other consensual rights which it is entitled to exercise pursuant to
Section 4.4(a)(i). Each Grantor hereby grants the Bank an irrevocable proxy,
with full power of substitution, coupled with an interest, to exercise all
voting and other consensual rights pertaining to the Collateral, exercisable if
and to the extent that the Bank is entitled to exercise such rights pursuant to
Section 4.4(a)(ii). All third parties are entitled to rely conclusively on a
representation by the Bank that it is entitled to exercise such power of
attorney.

              (b) DISTRIBUTIONS.

              (i) GENERAL. Subject to Section 4.4(b)(ii), the Grantors shall be
entitled to receive and retain all Distributions.

              (ii) CERTAIN RIGHTS OF BANK. If an Event of Default has occurred
and is continuing, all rights of any Grantor to receive and retain the
Distributions that it would otherwise be authorized to receive and retain
pursuant to Section 4.4(b)(i) shall automatically cease, and all such rights
shall thereupon vest in the Bank. Such Distributions shall be Collateral, and
shall be forthwith delivered to the Custodian to hold as such.

              (iii) PAYMENT OVER. If any Grantor receives any payment or
property which, pursuant to Section 4.4(b)(ii), it is not entitled to retain,
such payment or property shall be received in trust for the benefit of the Bank,
shall be segregated from other funds and property of such Grantor, and shall be
forthwith delivered to the Custodian as Collateral in the same form as so
received (with any necessary endorsement).

              4.5. FURTHER ASSURANCES.

              (a) GENERAL. Each Grantor shall from time to time, at its expense,
promptly execute and deliver all further instruments and agreements, and take
all further actions, that may be necessary or appropriate, or that the Bank may
reasonably request, in order to perfect or protect any assignment, pledge or
security interest granted or purported to be granted hereby or to enable the
Bank to exercise or enforce its rights and remedies hereunder. Without limiting
the generality of the foregoing, each Grantor will execute and file such
financing or continuation statements, or amendments thereto, and such other
instruments or notices, as may be necessary or desirable, or as the Bank may
request, in order to perfect and preserve any assignment, pledge or security
interest granted or purported to be granted hereby.

              (b) FILINGS, ETC. Each Grantor hereby authorizes the Bank to file
this Agreement with the Registrar of Companies in Bermuda and the Irish
Registrar of Companies and to file one or more financing or continuation
statements, and amendments thereto, relating to any Collateral without the
signature of such Grantor where permitted by law. A photocopy or other
reproduction of this Agreement or any financing statement covering any
Collateral shall be sufficient as a financing statement or other filing required
to perfect a security interest in the Collateral where permitted by law, it
being understood that the filing of an original of this Agreement or a certified
copy thereof with the Registrar of Companies in Bermuda and the Irish Registrar
of Companies is required to perfect the security interest granted hereunder.

                                    ARTICLE V
                     CERTAIN RIGHTS AND REMEDIES OF THE BANK

              5.1. BANK MAY PERFORM. If any Grantor fails to perform any
obligation under or in connection with this Agreement, the Bank may itself
perform or cause performance of such obligation, and the expenses of the Bank
incurred in connection therewith shall be payable by the Grantors pursuant to
Section 6.4. The Bank may from time to time take any other action which the Bank
deems necessary or appropriate for the maintenance, preservation or protection
of any of the Collateral or of its security interest therein.

              5.2. NO DUTY TO EXERCISE POWERS. The powers of the Bank under and
in connection with this Agreement are solely to protect its interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.

              5.3. DUTIES OF BANK. Except for exercise of reasonable care in the
custody and preservation of any Collateral in its possession and accounting for
moneys received by it pursuant to this Agreement, the Bank (in its capacity as
such) shall have no duty as to any Collateral. In any event the Bank (a) shall
have no duty to take any steps to preserve rights against prior parties or any
other rights pertaining to any Collateral, (b) shall have no duty as to
ascertaining or taking action with respect to calls, conversions, exchanges,
tenders, maturities or other matters pertaining to any Collateral, whether or
not the Bank has any knowledge of such matters, and (c) shall not be liable for
any action, omission, insolvency or default on the part of any agent or
custodian (other than the Bank) appointed by the Bank in good faith. The Bank
shall be deemed to have exercised reasonable care in the custody and
preservation of Collateral in its possession if it takes such action for such
purpose as the Grantors request in writing from time to time (but failure to
take any such action shall not in itself be deemed a failure to exercise
reasonable care or evidence of such failure). Subject only to the performance by
the Bank of its duties set forth in this Section 5.3, risk of loss, damage and
diminution in value of the Collateral, of whatever nature and however caused,
shall be on the Grantors.

              5.4. REMEDIES. Upon the occurrence of an Event of Default, the
Bank shall have all the rights and remedies available to it under law or at
equity, including those of a secured party under the UCC (whether or not, to the
extent permitted by applicable law, the UCC is in effect in the jurisdiction
where the rights and remedies are asserted) or applicable commercial or other
law, and may immediately exercise any and all such rights and remedies whether
or not the Bank has made any demand of the Grantors, taken any action of any
nature against the Grantors or resorted to any other collateral which the Bank
may have with respect to the Secured Obligations, all as the Bank shall, in its
sole discretion,

                                       11
<PAGE>

determine. Upon the occurrence of an Event of Default, the Bank shall have the
right to cause the Collateral to be reregistered in the Bank's sole name or the
name of it's nominee and shall have the right, to the fullest extent permitted
by applicable law, to direct the Custodian to sell all or any part of the
Collateral in a commercially reasonable manner upon any exchange or at any
public or private sale at the option of the Bank at any time or times without
advertisement or demand or notice to the Grantors (all of which are hereby
waived), except such notice as is required by applicable statute and cannot be
waived; with the right on the part of the Bank or its nominee to become the
purchaser thereof at any such sale (unless prohibited by statute). Without
limiting the generality of the foregoing, it is contemplated that the Bank will
use good faith efforts to refrain from causing the Custodian to liquidate
substantially more securities constituting Collateral than the Bank determines
or estimates are necessary to generate the cash amounts referred to in the
second sentence of Section 5.6 hereof, it being understood that, without
limiting the generality of Section 5.3 or the preceding sentence, the Bank shall
have no obligation or liability to any Grantor on account of liquidations of
such securities yielding proceeds in excess of such cash amounts and the Bank
shall not have responsibility to marshal assets or otherwise refrain from
exercising its sole and absolute discretion in determining when to sell
Collateral and which Collateral to sell. If any notification of intended sale of
any of the Collateral is required by law, such notification shall be deemed
reasonable if made in accordance with Section 6.3 hereof at least five days
before such sale. It is understood that the Bank may cause the Custodian to
dispose of the Collateral or any of it through any of the Bank's securities
brokerage affiliates. The Bank shall be deemed to have exercised reasonable care
in the custody and preservation of the Collateral if the Collateral is accorded
treatment substantially equal to that which the Bank accords its own property,
it being understood that the Bank shall not have any responsibility for taking
any necessary steps to preserve rights against parties with respect to the
Collateral. In no event shall the Bank be deemed a trustee of or fiduciary in
respect of the Collateral. The proceeds of each collection, sale or other
disposition under this Section 5.4 shall be promptly applied in accordance with
Section 5.6 hereof. Each of the Grantors recognizes that, by reason of certain
prohibitions contained in the Securities Act of 1933, as amended, and applicable
state securities laws, the Bank may be compelled, with respect to any sale of
all or any part of the Collateral, to limit purchasers to those who will agree,
among other things, to acquire the Collateral for their own account, for
investment and not with a view to the distribution or resale thereof.

              5.5. APPOINTMENT OF BANK AS ATTORNEY-IN-FACT. Each Grantor hereby
appoints and constitutes the Bank, its successors and assigns, as such Grantor's
agent and attorney-in-fact for the purpose of effecting, perfecting, and
continuing the grant of security interest in the Collateral to the Bank under
this Agreement and the exercise of the Bank's rights and remedies upon the
occurrence of an Event of Default hereunder and taking any action or executing
any document or instrument that the Bank deems necessary or convenient for such
purpose, including the power to endorse and deliver checks, notes and other
instruments for the payment of money in the name of and on behalf of such
Grantor, to endorse and deliver in the name of and on behalf of such Grantor
securities or other certificates and execute and deliver in the name of or on
behalf of such Grantor instruments to the issuers of uncertificated securities
and to execute and file in the name of and on behalf of such Grantor financing
statements, mortgages, charges or similar documents and continuations and
amendments thereto. This appointment is coupled with an interest and is
irrevocable and will not be affected by the bankruptcy or insolvency of such
Grantor or any circumstances whatsoever. Each Grantor agrees that the Custodian,
each Investment Manager, the issuers of any Collateral or any registrar or
transfer agent shall be entitled to accept the provisions hereof as conclusive
evidence of the Bank's rights to effect any transfer pursuant to this Agreement
and the authority granted to the Bank hereunder, notwithstanding any other
notice as direction to the contrary heretofore or hereinafter given by such
Grantor or any other party.

              5.6. APPLICATION OF PAYMENTS. All cash held by the Bank as
Collateral and all cash proceeds received by the Bank in respect of any sale of,
collection from, or other realization upon any of the Collateral, may in the
discretion of the Bank be held by the Bank as collateral for the Secured
Obligations, or then or at any time thereafter applied (after payment of any
amounts payable to the Bank pursuant to Section 6.4) in whole or part by the
Bank to the Secured Obligations (whether or not then due) in such order as the
Bank may elect, but not in contravention of the express terms hereof. If and
when all Secured Obligations shall have been paid in cash in full and all
Letters of Credit shall have terminated, any surplus of such cash or cash
proceeds held by the Bank shall be paid over to the Grantors or as otherwise
required by law. If the proceeds of sale, collection or other realization of or
upon the Collateral pursuant to this Section 5.6 hereof are insufficient to
cover the costs and expenses of such

                                       12
<PAGE>

realization and the payment in full of the Secured Obligations, the Grantors
shall remain liable for any deficiency.

                                   ARTICLE VI
                                  MISCELLANEOUS

              6.1. AMENDMENTS, ETC. No amendment to or waiver of any provision
of this Agreement, and no consent to any departure by any Grantor herefrom,
shall in any event be effective unless in a writing manually signed by the Bank.
Any such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.

              6.2. NO IMPLIED WAIVER; REMEDIES CUMULATIVE. No delay or failure
of the Bank in exercising any right or remedy under this Agreement shall operate
as a waiver thereof; nor shall any single or partial exercise of any such right
or remedy preclude any other or further exercise thereof or the exercise of any
other right or remedy. The rights and remedies of the Bank under this Agreement
are cumulative and not exclusive of any other rights or remedies available
hereunder, under any other agreement, at law, or otherwise.

              6.3. NOTICES. Unless otherwise specified in this Agreement,
notices shall be in writing and shall be effective, if to a Grantor, when
received by such Grantor c/o XL Capital Ltd. at XL House, One Bermudiana Road,
Hamilton HM11, Bermuda Attn: General Counsel and, if to the Bank, when received
at 388 Greenwich Street, 22nd Floor, New York, NY 10013 Attn: Mike Taylor, or,
in any case, such other address as the Bank, on the one hand, or any of the
Grantors, on the other hand, may notify the other in writing. The Grantors and
the Bank further agree that, if any notice given by a party triggers an
obligation on the part of the party receiving the notice which requires an
affirmative action to be taken by such receiving party within five Business Days
of the receipt of such notice, then such notice shall be given by telecopier.

              6.4. INDEMNITY AND EXPENSES.

              (a) INDEMNITY. Each Grantor agrees, jointly and severally, to
indemnify the Bank from and against any and all claims, losses, liabilities and
expenses (including reasonable attorney's fees and expenses) arising out of or
resulting from this Agreement (including, without limitation, enforcement of
this Agreement), except claims, losses, liabilities and expenses resulting
solely from the gross negligence or willful misconduct of the Bank.

              (b) EXPENSES. Each Grantor agrees, jointly and severally, to pay
upon demand to the Bank the amount of all reasonable fees and expenses,
including the reasonable fees and expenses of its counsel (which, in any event,
shall be limited to one counsel in any one jurisdiction) and of any experts and
agents, which the Bank may incur in connection with (i) the administration of
this Agreement, (ii) any Event of Default and any enforcement or collection
proceeding resulting therefrom, including, without limitation, all manner of
participation in or other involvement with (x) bankruptcy, insolvency,
receivership, foreclosure, winding up or liquidation proceedings, or any actual
or attempted sale, or any exchange, enforcement, collection, compromise or
settlement in respect of any of the Collateral, and for the care of the
Collateral and defending or asserting rights and claims of the Bank in respect
thereof, by litigation or otherwise, (y) judicial or regulatory proceedings and
(z) workout, restructuring or other negotiations or proceedings (whether or not
the workout, restructuring or transaction contemplated thereby is consummated),
(iii) the enforcement of this Section 6.4 or (iv) the failure by any Grantor to
perform or observe any of the provisions hereof; PROVIDED that the Grantors
shall not be liable for any fees and expenses resulting solely from the gross
negligence or willful misconduct of the Bank. All such fees and expenses shall
be Secured Obligations entitled to the benefits of the collateral security
provided pursuant to Section 2.1 hereof. Without limiting the foregoing, the
Grantors shall pay and reimburse the Bank on demand for all reasonable fees and
expenses incurred by them in liquidating the Collateral pursuant hereto.

                                       13
<PAGE>

              6.5. ENTIRE AGREEMENT. This Agreement constitutes the entire
agreement of the parties hereto with respect to the subject matter hereof and
supersedes all prior and contemporaneous understandings and agreements.

              6.6. SURVIVAL. The obligations of each Grantor under Sections 2.5,
2.9 and 6.4 shall survive termination of this Agreement and all other events and
conditions whatever. All representations and warranties of the Grantors
contained in or made in connection with this Agreement shall survive, and shall
not be waived by, the execution and delivery of this Agreement, any
investigation by or knowledge of the Bank, any extension of credit, termination
of this Agreement, or any other event or circumstance whatever.

              6.7. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, and all such
counterparts shall constitute but one and the same agreement.

              6.8. SEVERABILITY. If any one or more of the provisions hereof or
in any other related document should for any reason be invalid, illegal, or
unenforceable in any respect, the validity, legality, or enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby, and such invalid, illegal, or unenforceable provision shall be
deemed modified to the extent necessary to render it valid while most nearly
preserving its original intent.

              6.9. CONSTRUCTION. In this Agreement, unless the context otherwise
clearly requires, references to the plural include the singular, the singular
the plural, and the part the whole; the neuter case includes the masculine and
feminine cases; and "or" is not exclusive. In this Agreement, any references to
property (and similar terms) include an interest in such property (or other item
referred to); "include," "includes," "including" and similar terms are not
limiting; and "hereof," "herein," "hereunder" and similar terms refer to this
Agreement as a whole and not to any particular provision. Section and other
headings in this Agreement are for reference only and shall not affect the
interpretation of this Agreement in any respect. Section and other references in
this Agreement are to this Agreement unless otherwise specified.

              6.10. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon
each Grantor and its successors and assigns, and shall inure to the benefit of
and be enforceable by the Bank and its successors and assigns.

              6.11. SUCCESSOR CUSTODIAN. The Grantors may appoint a successor
Custodian upon no less than 60 days prior written notice to the Bank, which
successor Custodian shall become the Custodian for all purposes of this
Agreement upon establishing securities accounts which will become Designated
Accounts, receiving all Collateral required to be deposited to such securities
accounts and crediting such Collateral to such securities accounts; PROVIDED
that (i) such successor Custodian shall be an institution qualified to maintain
securities accounts for customers or depositors and to perform the functions of
a securities intermediary with respect to the Collateral, of recognized national
standing as a securities intermediary and custodian, and have a capitalization
of not less than $500,000,000, (ii) such successor Custodian shall have its
principal place of business in the United States, which principal place of
business shall be located in, and the securities accounts shall be maintained

custodian acknowledgment in favor of the Bank and such other agreements and
documentation which are reasonably required by the Bank, all in form and
substance reasonably satisfactory to the Bank; PROVIDED FURTHER that upon the
occurrence and during the continuance of an Event of Default, the Bank shall
have the absolute right at any time to appoint itself as successor Custodian. In
the event the Bank appoints itself as successor Custodian as set forth above,
(i) the Grantors shall cause the then current Custodian to transfer all

shall continue to be subject to the security interest created hereby.

              6.12. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, EXCLUSIVE OF
CHOICE OF LAW PRINCIPLES.

              6.13. CONSENT TO JURISDICTION; SERVICE OF PROCESS. Each Grantor
irrevocably submits to the non-exclusive jurisdiction of any state or federal
court sitting in New York, New York, for itself and in respect of any of its
property and, if a law other than the law of the State of New York, has been
chosen to govern a Letter of Credit, each Grantor also irrevocably submits to
the non-exclusive jurisdiction of any state or federal court sitting in such
jurisdiction, in each case in connection with any suit, action or proceeding
relating to this Agreement or such Letter of Credit. Each Grantor agrees not to
bring any action or proceeding against the Bank in any jurisdiction not
described in the immediately preceding sentence. Each Grantor irrevocably waives
any objection to venue or any claim of inconvenient forum in connection with any
such action, suit or proceeding. Each Grantor agrees that any service of process
or other notice of legal process may be served upon it by mail or hand delivery
if sent to CT Corporation System at 111 Eighth Avenue, New York, NY 10016 which
the Grantors now designate as their authorized agent for the service of process
in the courts in the State of New York. (If no authorized agent is designated in
the space provided above, each Grantor agrees that process shall be deemed
served if sent to its address given for notices under this Agreement.) Each
Grantor agrees that nothing in this Agreement shall affect the Bank's right to
serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against any Grantor in any other jurisdiction.
Each Grantor agrees that final judgment against it in any action or proceeding
shall be enforceable in any other jurisdiction within or outside the United
States of America by suit on the judgment, a certified copy of which shall be
conclusive evidence of the judgment.

              6.14. WAIVER OF IMMUNITY. To the extent any Grantor now has or
hereafter acquires any immunity from jurisdiction of any court or from suit,
jurisdiction, attachment before or after judgment or execution or from any other
legal process with respect to itself or its property, such Grantor irrevocably
waives such immunity with respect to its obligations under this Agreement.

              6.15. SET-OFF. If any Event of Default shall occur and be
continuing, the Bank may set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by the Bank to or for the credit or the account
of any of the Grantors ("Deposits") against any and all of the Grantors'
obligations under this Agreement, irrespective of whether or not the Bank shall
have made any demand under this Agreement and although such Deposits or
obligations may be unmatured or contingent. The Bank's rights under this section
are in addition to other rights and remedies (including other rights of set-off)
which the Bank may have under this Agreement or applicable law.
