aggregate principal amount of Swing Line Loans outstanding at any time shall not
exceed the Swing Line Commitment then in effect (notwithstanding that the Swing
Line Loans outstanding at any time, when aggregated with the Swing Line Lender's
other outstanding Revolving Credit Loans hereunder, may exceed the Swing Line
Commitment then in effect or such Swing Line Lender's Revolving Credit
Commitment then in effect) and (ii) the Borrowers shall not request, and the
Swing Line Lender shall not make, any Swing Line Loan if, after giving effect to
the making of such Swing Line Loan, the aggregate amount of the Available
Revolving Credit Commitments would be less than zero. During the Revolving
Credit Commitment Period, the Borrowers may use the Swing Line Commitment by
borrowing, repaying and reborrowing, all in accordance with the terms and
conditions hereof. Swing Line Loans shall be Base Rate Loans only.

          (b) The Borrowers shall repay all outstanding Swing Line Loans on the
Revolving Credit Termination Date. Each payment in respect of Swing Line Loans
shall be made to the Swing Line Lender.

          2.4 PROCEDURE FOR SWING LINE BORROWING; REFUNDING OF SWING LINE LOANS.
(a) A Borrower may borrow under the Swing Line Commitment on any Business Day
during the Revolving Credit Commitment Period, PROVIDED, such Borrower shall
give the Swing Line Lender irrevocable telephonic notice confirmed promptly in
writing (which telephonic notice must be received by the Swing Line Lender not
later than 1:00 P.M., New York City time, on the proposed Borrowing Date),
specifying (i) the amount to be borrowed and (ii) the requested Borrowing Date.
Each borrowing under the Swing Line Commitment shall be in an amount equal to
$500,000 or a whole multiple of $100,000 in excess thereof. Not later than 3:00
P.M., New York City time, on the Borrowing Date specified in the borrowing
notice in respect of any Swing Line Loan, the Swing Line Lender shall make
available to the Administrative Agent at the Funding Office an amount in
immediately available funds equal to the amount of such Swing Line Loan. The
Administrative Agent shall make the proceeds of such Swing Line Loan available
to such Borrower on such Borrowing Date in like funds as received by the
Administrative Agent.

          (b) The Swing Line Lender, at any time and from time to time in its
sole and absolute discretion may, on behalf of a Borrower (which hereby
irrevocably directs the Swing Line Lender to act on its behalf), on one Business
Day's notice given by the Swing Line Lender no later than 12:00 Noon, New York
City time, request each Lender to make, and each Lender hereby agrees to make, a
Revolving Credit Loan, in an amount equal to such Lender's Revolving Credit
Percentage of the aggregate amount of the Swing Line Loans (the "REFUNDED SWING
LINE LOANS") outstanding on the date of such notice, to repay the Swing Line
Lender. Each Lender shall make the amount of such Revolving Credit Loan
available to the Administrative Agent at

<Page>

                                                                              21

the Funding Office in immediately available funds, not later than 10:00 A.M.,
New York City time, one Business Day after the date of such notice. The proceeds
of such Revolving Credit Loans shall be made immediately available by the
Administrative Agent to the Swing Line Lender for application by the Swing Line
Lender to the repayment of the Refunded Swing Line Loans. Upon the written
request of any Lender, the Administrative Agent will, within three Business Days
of such request, inform such Lender of the aggregate amount of Swing Line Loans
outstanding on the date of such request.

          (c) If prior to the time a Revolving Credit Loan would have otherwise
been made pursuant to Section 2.4(b), one of the events described in Section
8(f) shall have occurred and be continuing with respect to the Borrowers, or if
for any other reason, as determined by the Swing Line Lender in its sole
discretion, Revolving Credit Loans may not be made as contemplated by Section
2.4(b), each Lender shall, on the date such Revolving Credit Loan was to have
been made pursuant to the notice referred to in Section 2.4(b) (the "REFUNDING
DATE"), purchase for cash an undivided participating interest in the then
outstanding Swing Line Loans by paying to the Swing Line Lender an amount (the
"SWING LINE PARTICIPATION AMOUNT") equal to (i) such Lender's Revolving Credit
Percentage TIMES (ii) the sum of the aggregate principal amount of Swing Line
Loans then outstanding which were to have been repaid with such Revolving Credit
Loans.

          (d) Whenever, at any time after the Swing Line Lender has received
from any Lender such Lender's Swing Line Participation Amount, the Swing Line
Lender receives any payment on account of the Swing Line Loans, the Swing Line
Lender will distribute to such Lender its Swing Line Participation Amount
(appropriately adjusted, in the case of interest payments, to reflect the period
of time during which such Lender's participating interest was outstanding and
funded and, in the case of principal and interest payments, to reflect such
Lender's PRO RATA portion of such payment if such payment is not sufficient to
pay the principal of and interest on all Swing Line Loans then due); PROVIDED,
HOWEVER, that in the event that such payment received by the Swing Line Lender
is required to be returned, such Lender will return to the Swing Line Lender any
portion thereof previously distributed to it by the Swing Line Lender.

          (e) Each Lender's obligation to make the Loans referred to in Section
2.4(b) and to purchase participating interests pursuant to Section 2.4(c) shall
be absolute and unconditional and shall not be affected by any circumstance,
including, without limitation, (i) any setoff, counterclaim, recoupment, defense
or other right which such Lender or the Borrowers may have against the Swing
Line Lender, the Borrowers or any other Person for any reason whatsoever; (ii)
the occurrence or continuance of a Default or an Event of Default or the failure
to satisfy any of the other conditions specified in Section 5; (iii) any adverse
change in the condition (financial or otherwise) of the Borrowers; (iv) any
breach of this Agreement or any other Loan Document by the Borrowers or any
Lender; or (v) any other circumstance, happening or event whatsoever, whether or
not similar to any of the foregoing.

          2.5 REPAYMENT OF LOANS; EVIDENCE OF DEBT. (a) Each of the Borrowers
hereby unconditionally promise to pay to the Administrative Agent for the
account of the appropriate Lender (i) the then unpaid principal amount on the
Revolving Credit Termination Date (or on such earlier date on which the Loans
become due and payable pursuant to Section 8) of each Revolving Credit Loan of
such Lender made to such Borrower and (ii) the then unpaid principal

<Page>

                                                                              22

amount on the Revolving Credit Termination Date (or on such earlier date on
which the Loans become due and payable pursuant to Section 8) of each Swing Line
Loan of such Swing Line Lender made to such Borrower. Each of the Borrowers
hereby further agrees to pay interest to the Administrative Agent for the
account of the appropriate Lender on the unpaid principal amount of the Loans
made to it from time to time outstanding from the date hereof until payment in
full thereof at the rates per annum, and on the dates, set forth in Section
2.11.

          (b) Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing indebtedness of each Borrower to such Lender
resulting from each Loan of such Lender from time to time, including the amounts
of principal and interest payable and paid to such Lender from time to time
under this Agreement.

          (c) The Administrative Agent, on behalf of each Borrower, shall
maintain the Register pursuant to Section 10.6(d), and a subaccount therein for
each Lender, in which shall be recorded (i) the amount of each Loan to such
Borrower made hereunder and any Note evidencing such Loan, the Type of such Loan
and each Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from such Borrower to each
Lender hereunder and (iii) both the amount of any sum received by the
Administrative Agent hereunder from or for the account of such Borrower and each
Lender's share thereof.

          (d) The entries made in the Register and the accounts of each Lender
maintained pursuant to Section 2.5(b) shall, to the extent permitted by
applicable law, be PRIMA FACIE evidence of the existence and amounts of the
obligations of each Borrower therein recorded; PROVIDED, HOWEVER, that the
failure of any Lender or the Administrative Agent to maintain the Register or
any such account, or any error therein, shall not in any manner affect the
obligation of any Borrower to repay (with applicable interest) the Loans made to
it by such Lender in accordance with the terms of this Agreement.

          (e) Each of the Borrowers agrees that, upon the request to the
Administrative Agent by any Lender, it will execute and deliver to such Lender a
promissory note of such Borrower evidencing any Revolving Credit Loans or Swing
Line Loans, as the case may be, made by such Lender to such Borrower,
substantially in the forms of EXHIBIT C-1 or C-2, respectively, with appropriate
insertions as to date and principal amount.

          2.6 FACILITY FEE, UTILIZATION FEE, ETC. (a) Fund American agrees to
pay to the Administrative Agent for the account of each Lender a facility fee
for the period from and including the Closing Date to the last day of the
Revolving Credit Commitment Period, computed at the Facility Fee Rate on the
average daily amount of the Revolving Credit Commitment of such Lender during
the period for which payment is made, payable quarterly in arrears on the first
Business Day of each January, April, July and October and on the Revolving
Credit Termination Date, commencing on the first of such dates to occur after
the Closing Date.

          (b) If during any quarter the average daily balance of the aggregate
amount of outstanding Loans plus outstanding L/C Obligations is greater than
fifty percent (50%) of the Total Revolving Credit Commitment then Fund American
agrees to pay to the Administrative Agent, quarterly, in arrears, for the
account of each Lender, a utilization fee for such quarter from and including
the first day of such quarter to the last day of such quarter, computed at the

<Page>

                                                                              23

Utilization Fee Rate on the average daily amount of each Lender's Revolving
Credit Percentage of outstanding Loans plus outstanding L/C Obligations. The
utilization fee, if applicable, will be added to the Applicable Margin, such
that payments of the Utilization Fee will be due at the same times as interest
payments relating to the same borrowings.

          (c) The Borrowers agree to pay to the Syndication Agent the fees in
the amounts and on the dates from time to time agreed to in writing by the
Borrowers and the Syndication Agent.

          (d) The Borrowers agree to pay to the Joint Lead Arrangers the fees in
the amounts and on the dates from time to time agreed to in writing by the
Borrowers and the Joint Lead Arrangers.

          (e) The Borrowers agree to pay to the Administrative Agent the fees in
the amounts and on the dates from time to time agreed to in writing by the
Borrowers and the Administrative Agent.

          2.7 TERMINATION OR REDUCTION OF REVOLVING CREDIT COMMITMENTS. White
Mountains shall have the right, upon not less than three Business Days' notice
to the Administrative Agent, to terminate the Revolving Credit Commitments or,
from time to time, to reduce the aggregate amount of the Revolving Credit
Commitments; PROVIDED that no such termination or reduction of Revolving Credit
Commitments shall be permitted if, after giving effect thereto and to any
prepayments of the Revolving Credit Loans and Swing Line Loans made on the
effective date thereof, the Total Revolving Extensions of Credit would exceed
the Total Revolving Credit Commitments; PROVIDED, FURTHER, that a notice of
termination of the Revolving Credit Commitments delivered by White Mountains may
state that such notice is conditioned upon the effectiveness of other credit
facilities, in which case such notice may be revoked by White Mountains (by
notice to the Administrative Agent on or prior to the specified effective date)
if such condition is not satisfied. Any such reduction shall be in an amount
equal to $1,000,000, or a whole multiple thereof, and shall reduce permanently
the Revolving Credit Commitments then in effect.

          2.8 OPTIONAL PREPAYMENTS. (a) A Borrower may at any time and from time
to time prepay the Loans made to such Borrower, in whole or in part, without
premium or penalty, upon notice delivered to the Administrative Agent at least
three Business Days prior thereto in the case of Eurodollar Loans and at least
one Business Day prior thereto in the case of Base Rate Loans, which notice
shall specify the date and amount of prepayment and whether the prepayment is of
Eurodollar Loans or Base Rate Loans; provided, that (i) if a Eurodollar Loan is
prepaid on any day other than the last day of the Interest Period applicable
thereto, such Borrower shall also pay any amounts owing pursuant to Section 2.17
and (ii) no prior notice is required for the prepayment of Swing Line Loans;
PROVIDED, FURTHER, that, if a notice of prepayment is given in connection with a
conditional notice of termination of the Revolving Credit Commitments as
contemplated by Section 2.7, then such notice of prepayment may be revoked if
such notice of termination is revoked in accordance with Section 2.7. Upon
receipt of any such notice the Administrative Agent shall promptly notify the
Lenders thereof. If any such notice is given, the amount specified in such
notice shall be due and payable on the date specified therein, together with
(except in the case of Base Rate Loans) accrued interest to such

<Page>

                                                                              24

date on the amount prepaid. Partial prepayments of Loans shall be in an
aggregate principal amount of $1,000,000 or a whole multiple thereof. Partial
prepayments of Swing Line Loans shall be in an aggregate principal amount of
$100,000 or a whole multiple thereof.

          2.9 CONVERSION AND CONTINUATION OPTIONS. (a) A Borrower may elect from
time to time to convert Eurodollar Loans made to such Borrower to Base Rate
Loans by giving the Administrative Agent at least two Business Days' prior
irrevocable notice of such election, provided that any such conversion of
Eurodollar Loans may be made only on the last day of an Interest Period with
respect thereto. A Borrower may elect from time to time to convert Base Rate
Loans made to such Borrower to Eurodollar Loans by giving the Administrative
Agent at least three Business Days' prior irrevocable notice of such election
(which notice shall specify the length of the initial Interest Period therefor),
PROVIDED that no Base Rate Loan may be converted into a Eurodollar Loan (i) when
any Event of Default has occurred and is continuing and the Administrative Agent
or the Majority Lenders have determined in its or their sole discretion not to
permit such conversions or (ii) after the date that is one month prior to the
Revolving Credit Termination Date. Upon receipt of any such notice the
Administrative Agent shall promptly notify the Lenders thereof.

          (b) A Borrower may elect to continue any Eurodollar Loan made to such
Borrower as such upon the expiration of the then current Interest Period with
respect thereto by giving irrevocable notice to the Administrative Agent, in
accordance with the applicable provisions of the term "Interest Period" set
forth in Section 1.1, of the length of the next Interest Period to be applicable
to such Loans, PROVIDED that no Eurodollar Loan may be continued as such (i)
when any Event of Default has occurred and is continuing and the Administrative
Agent or the Majority Lenders have, determined in its or their sole discretion
not to permit such continuations or (ii) after the date that is one month prior
to the Revolving Credit Termination Date, and PROVIDED, FURTHER, that if such
Borrower shall fail to give any required notice as described above in this
paragraph or if such continuation is not permitted pursuant to the preceding
proviso, such Loans shall be converted automatically to Base Rate Loans on the
last day of such then expiring Interest Period. Upon receipt of any such notice
the Administrative Agent shall promptly notify the Lenders thereof.

          2.10 MAXIMUM NUMBER OF EURODOLLAR LOANS. Notwithstanding anything to
the contrary in this Agreement, all borrowings, conversions, continuations and
optional prepayments of Eurodollar Loans and all selections of Interest Periods
shall be in such amounts and be made pursuant to such elections so that no more
than seven Eurodollar Loans shall be outstanding at any one time.

          2.11 INTEREST RATES AND PAYMENT DATES. (a) Each Eurodollar Loan shall
bear interest for each day during each Interest Period with respect thereto at a
rate per annum equal to the Eurodollar Rate determined for such day plus the
Applicable Margin.

          (b) Each Base Rate Loan shall bear interest at a rate per annum equal
to the Base Rate.

          (c) (i) If all or a portion of the principal amount of any Loan or
Reimbursement Obligation shall not be paid when due (whether at the stated
maturity, by acceleration or

<Page>

                                                                              25

otherwise), such overdue amount shall bear interest at a rate per annum that is
equal to (x) in the case of the Loans, the rate that would otherwise be
applicable thereto pursuant to the foregoing provisions of this Section PLUS 2%
or (y) in the case of Reimbursement Obligations, the rate applicable to Base
Rate Loans PLUS 2%, and (ii) if all or a portion of any interest payable on any
Loan or Reimbursement Obligation or any facility fee or other amount payable
hereunder shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), such overdue amount shall bear interest at a rate
per annum equal to the rate then applicable to Base Rate Loans PLUS 2%, in each
case, with respect to clauses (i) and (ii) above, from the date of such
non-payment until such amount is paid in full (after as well as before
judgment).

          (d) Interest shall be payable in arrears on each Interest Payment
Date, PROVIDED that interest accruing pursuant to paragraph (c) of this Section
shall be payable from time to time on demand.

          2.12 COMPUTATION OF INTEREST AND FEES. (a) Interest, fees and
commissions payable pursuant hereto shall be calculated on the basis of a
365-day (or 366-day, as the case may be) year for the actual days elapsed,
except that, with respect to Eurodollar Loans, the interest thereon shall be
calculated on the basis of a 360-day year for the actual days elapsed. The
Administrative Agent shall as soon as practicable notify the Borrowers and the
Lenders of each determination of a Eurodollar Rate. Any change in the interest
rate on a Loan resulting from a change in the Base Rate shall become effective
as of the opening of business on the day on which such change becomes effective.
The Administrative Agent shall as soon as practicable notify the Borrowers and
the Lenders of the effective date and the amount of each such change in interest
rate.

          (b) Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrowers and the Lenders in the absence of manifest error.

          2.13 INABILITY TO DETERMINE INTEREST RATE. If prior to the first day
of any Interest Period:

          (a) the Administrative Agent shall have determined (which
     determination shall be conclusive and binding upon the Borrowers) that, by
     reason of circumstances affecting the relevant market, adequate and
     reasonable means do not exist for ascertaining the Eurodollar Rate for such
     Interest Period, or

          (b) the Administrative Agent shall have received notice from the
     Majority Lenders that the Eurodollar Rate determined or to be determined
     for such Interest Period will not adequately and fairly reflect the cost to
     such Lenders (as conclusively certified by such Lenders) of making or
     maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrowers and the relevant Lenders as soon as practicable thereafter. If such
notice is given (x) any Eurodollar Loans requested to be made on the first day
of such Interest Period shall be made as Base Rate Loans, (y) any Loans that
were to have been converted on the first day of such Interest Period to

<Page>

                                                                              26

Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding
Eurodollar Loans shall be converted, on the last day of the then current
Interest Period with respect thereto, to Base Rate Loans. Until such notice has
been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be
made or continued as such, nor shall the Borrowers have the right to convert
Loans to Eurodollar Loans.

          2.14 PRO RATA TREATMENT AND PAYMENTS. (a) Each borrowing by the
Borrowers from the Lenders hereunder, each payment by the Borrowers on account
of any facility fee or Letter of Credit fee, and any reduction of the Revolving
Credit Commitments of the Lenders, shall be made pro rata according to the
respective Revolving Credit Percentages of the relevant Lenders. Each payment in
respect of utilization fees payable hereunder shall be applied to the amounts of
such obligations owing to the Lenders PRO RATA according to the respective
amounts then due and owing to the Lenders.

          (b) Each payment (including each prepayment) by the Borrowers on
account of principal of and interest on the Revolving Credit Loans of the
Borrowers shall be made PRO RATA according to the respective outstanding
principal amounts of the Revolving Credit Loans of the Borrowers then held by
the Lenders. Each payment in respect of Reimbursement Obligations in respect of
any Letter of Credit shall be made to the relevant Issuing Lender.

          (c) The application of any payment of Loans shall be made, FIRST, to
Base Rate Loans and, SECOND, to Eurodollar Loans. Each payment of the Loans
shall be accompanied by accrued interest to the date of such payment on the
amount paid.

          (d) All payments (including prepayments) to be made by the Borrowers
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made without setoff or counterclaim and shall be made prior to 12:00 Noon,
New York City time, on the due date thereof to the Administrative Agent, for the
account of the relevant Lenders, at the Payment Office, in Dollars and in
immediately available funds. Any payment made by the Borrowers after 12:00 Noon,
New York City time, on any Business Day shall be deemed to have been made on the
next following Business Day. The Administrative Agent shall distribute such
payments to the Lenders promptly upon receipt in like funds as received. If any
payment hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day. If any payment on a Eurodollar Loan becomes
due and payable on a day other than a Business Day, the maturity thereof shall
be extended to the next succeeding Business Day unless the result of such
extension would be to extend such payment into another calendar month, in which
event such payment shall be made on the immediately preceding Business Day. In
the case of any extension of any payment of principal pursuant to the preceding
two sentences, interest thereon shall be payable at the then applicable rate
during such extension.

          (e) Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing by a Borrower that such Lender will
not make the amount that would constitute its share of such borrowing available
to the Administrative Agent, the Administrative Agent may assume that such
Lender is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
such Borrower a corresponding amount. If such amount is not made available

<Page>

                                                                              27

to the Administrative Agent by the required time on the Borrowing Date therefor,
such Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon at a rate equal to the daily average Federal Funds Effective
Rate for the period until such Lender makes such amount immediately available to
the Administrative Agent. A certificate of the Administrative Agent submitted to
any Lender with respect to any amounts owing under this paragraph shall be
conclusive in the absence of manifest error. If such Lender's share of such
borrowing is not made available to the Administrative Agent by such Lender
within three Business Days after such Borrowing Date, the Administrative Agent
shall also be entitled to recover such amount with interest thereon at the rate
per annum applicable to Base Rate Loans, on demand, from such Borrower.

          (f) Unless the Administrative Agent shall have been notified in
writing by a Borrower prior to the date of any payment due to be made by such
Borrower hereunder that such Borrower will not make such payment to the
Administrative Agent, the Administrative Agent may assume that such Borrower is
making such payment, and the Administrative Agent may, but shall not be required
to, in reliance upon such assumption, make available to the Lenders their
respective pro rata shares of a corresponding amount. If such payment is not
made to the Administrative Agent by such Borrower within three Business Days
after such due date, the Administrative Agent shall be entitled to recover, on
demand, from each Lender to which any amount which was made available pursuant
to the preceding sentence, such amount with interest thereon at the rate per
annum equal to the daily average Federal Funds Effective Rate. Nothing herein
shall be deemed to limit the rights of the Administrative Agent or any Lender
against such Borrower.

          2.15 REQUIREMENTS OF LAW. (a) If the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof or compliance
by any Lender with any request or directive (whether or not having the force of
law) from any central bank or other Governmental Authority made subsequent to
the date hereof:

               (i) shall subject any Lender to any tax of any kind whatsoever
     with respect to this Agreement, any Letter of Credit, any Application or
     any Eurodollar Loan made by it, or change the basis of taxation of payments
     to such Lender in respect thereof (except for Non-Excluded Taxes covered by
     Section 2.16 and changes in the rate of tax on the overall net income of
     such Lender);

               (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender that is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or

               (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans to a Borrower or issuing or
participating in Letters of Credit issued at the request of a Borrower, or to
reduce any amount receivable hereunder in respect thereof, then, in

<Page>

                                                                              28

any such case, such Borrower shall promptly pay such Lender, upon its demand,
any additional amounts necessary to compensate such Lender for such increased
cost or reduced amount receivable. If any Lender becomes entitled to claim any
additional amounts pursuant to this Section, it shall promptly notify the
relevant Borrower (with a copy to the Administrative Agent) of the event by
reason of which it has become so entitled.

          (b) If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under or in respect of any Letter of
Credit to a level below that which such Lender or such corporation could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the relevant Borrower (with a copy to the
Administrative Agent) of a written request therefor, such Borrower shall pay to
such Lender such additional amount or amounts as will compensate such Lender or
such corporation for such reduction.

          (c) In addition to, and without duplication of, amounts which may
become payable from time to time pursuant to paragraphs (a) and (b) of this
Section 2.15, each Borrower agrees to pay to each Lender which requests
compensation under this paragraph (c) by notice to such Borrower, on the last
day of each Interest Period with respect to any Eurodollar Loan made by such
Lender to such Borrower, at any time when such Lender shall be required to
maintain reserves against "Eurocurrency liabilities" under Regulation D of the
Board of Governors of the Federal Reserve System (or, at any time when such
Lender may be required by the Board of Governors of the Federal Reserve System
or by any other Governmental Authority, whether within the United States or in
another relevant jurisdiction, to maintain reserves against any other category
of liabilities which includes deposits by reference to which the Eurodollar Rate
is determined as provided in this Agreement or against any category of
extensions of credit or other assets of such Lender which includes any such
Eurodollar Loans), an additional amount (determined by such Lender's calculation
or, if an accurate calculation is impracticable, reasonable estimate using such
reasonable means of allocation as such Lender shall determine) equal to the
actual costs, if any, incurred by such Lender during such Interest Period as a
result of the applicability of the foregoing reserves to such Eurodollar Loans.

          (d) A certificate as to any additional amounts payable pursuant to
this Section submitted by any Lender to a Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error. No
Lender shall be entitled to compensation under this Section 2.15 from a Borrower
for any costs incurred or reductions suffered more than 180 days prior to the
date that such Lender notifies such Borrower of the circumstances giving rise to
such increased costs or reductions and of such Lender's intention to claim
compensation therefor; provided that if a change of law giving rise to such
increased costs or reductions is retroactive, then the 180-day period referred
to above shall be extended to include the period of retroactive effect thereof.
The obligations of the Borrowers pursuant to this Section shall survive the

                                                                              29

termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

          2.16 TAXES. (a) Except as required by law, all payments made by the
Borrowers under this Agreement shall be made free and clear of, and without
deduction 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, excluding net income taxes and franchise and
doing business taxes (imposed in lieu of net income taxes) imposed on the
Administrative Agent or any Lender as a result of a present or former connection
between the Administrative Agent or such Lender and the jurisdiction of the
Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from
the Administrative Agent's or such Lender's having executed, delivered or
performed its obligations or received a payment under, or enforced, this
Agreement or any other Loan Document). If any such non-excluded taxes, levies,
imposts, duties, charges, fees, deductions or withholdings ("NON-EXCLUDED
TAXES") or any Other Taxes are required to be withheld from any amounts payable
to the Administrative Agent or any Lender hereunder, the amounts so payable to
the Administrative Agent or such Lender shall be increased to the extent
necessary to yield to the Administrative Agent or such Lender (after payment of
all Non-Excluded Taxes and Other Taxes) interest or any such other amounts
payable hereunder at the rates or in the amounts specified in this Agreement;
PROVIDED, HOWEVER, that no Borrower shall be required to increase any such
amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that
are attributable to such Lender's failure to comply with the requirements of
paragraph (d) or (e) of this Section or (ii) that are withholding taxes imposed
on amounts payable to such Lender at the time such Lender becomes a party to
this Agreement or designates a new lending office, except to the extent that
such Lender (or its assignor, if any) was entitled, at the time of designation
of a new lending office or assignment, to receive additional amounts from the
relevant Borrower with respect to such Non-Excluded Taxes pursuant to Section
2.16(a).

          (b) In addition, the Borrowers shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by
either of the Borrowers, as soon as practicable thereafter the relevant Borrower
shall send to the Administrative Agent for its own account or for the account of
the relevant Lender, as the case may be, a certified copy of an official receipt
received by such Borrower showing payment thereof (or other evidence of such
payment reasonably satisfactory to the Administrative Agent). If the relevant
Borrower fails, to pay any Non-Excluded Taxes or Other Taxes when due to the
appropriate taxing authority or fails to remit to the Administrative Agent the
required receipts or other required documentary evidence, such Borrower shall
indemnify the Administrative Agent and the Lenders for any incremental taxes,
interest or penalties that may become payable by the Administrative Agent or any
Lender as a result of any such failure. The agreements in this Section 2.16
shall survive the termination of this Agreement and the payment of the Loans and
all other amounts payable hereunder.

          (d) Each Lender (or Transferee) that is not (i) a citizen or resident
of the United States of America, (ii) a corporation, partnership or other entity
created or organized in or under

<Page>

                                                                              30

the laws of the United States of America (or any jurisdiction thereof), or (iii)
an estate or trust that is subject to U.S. federal income taxation regardless of
the source of its income (a "NON-U.S. LENDER") shall deliver to the Borrowers
and the Administrative Agent (or, in the case of a Participant, to the Lender
from which the related participation shall have been purchased) two copies of
either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI (or other
applicable form), or, in the case of a Non-U.S. Lender claiming exemption from
U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with
respect to payments of "portfolio interest", a statement substantially in the
form of EXHIBIT D and a Form W-8BEN (or other applicable form), or any
subsequent versions thereof or successors thereto properly completed and duly
executed by such Non-U.S. Lender claiming complete exemption from, or a reduced
rate of, U.S. federal withholding tax on all payments by the Borrowers under
this Agreement and the other Loan Documents. Such forms shall be delivered by
each Non-U.S. Lender on or before the date it becomes a party to this Agreement
(or, in the case of any Participant, on or before the date such Participant
purchases the related participation). In addition, each Non-U.S. Lender shall
deliver such forms promptly upon the obsolescence or invalidity of any form
previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall, as
soon as reasonably practicable, notify the Borrowers at any time it determines
that it is no longer in a position to provide any previously delivered
certificate to the Borrowers (or any other form of certification adopted by the
U.S. taxing authorities for such purpose). Notwithstanding any other provision
of this paragraph, a Non-U.S. Lender shall not be required to deliver any form
pursuant to this paragraph that such Non-U.S. Lender is not legally able to
deliver.

          (e) A Lender that is entitled to an exemption from or reduction of
non-U.S. withholding tax under the law of the jurisdiction in which a Borrower
is located, or any treaty to which such jurisdiction is a party, with respect to
payments under this Agreement shall deliver to such Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law or
reasonably requested by such Borrower, such properly completed and executed
documentation prescribed by applicable law or reasonably requested by the
Borrowers as will permit such payments to be made without withholding or at a
reduced rate, PROVIDED that such Lender is legally entitled to complete, execute
and deliver such documentation.

          2.17 INDEMNITY. Each Borrower agrees to indemnify each Lender for, and
to hold each Lender harmless from, any loss or expense that such Lender sustains
or incurs as a consequence of (a) default by such Borrower in making a borrowing
of, conversion into or continuation of Eurodollar Loans after such Borrower has
given a notice requesting the same in accordance with the provisions of this
Agreement, (b) default by such Borrower in making any prepayment after such
Borrower has given a notice thereof in accordance with the provisions of this
Agreement or (c) the making by such Borrower of a prepayment or conversion of
Eurodollar Loans on a day that is not the last day of an Interest Period with
respect thereto; PROVIDED that any request for indemnification made by a Lender
pursuant to this Section 2.17 shall be made within six months of the incurrence
of the loss or expense requested to be indemnified. Such indemnification may
include an amount equal to the excess, if any, of (i) the amount of interest
that would have accrued on the amount so prepaid, or not so borrowed, converted
or continued, for the period from the date of such prepayment or of such failure
to borrow, convert or continue to the last day of such Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period that
would have commenced on the date of such failure) in each case at the

<Page>

                                                                              31

applicable rate of interest for such Loans provided for herein (excluding,
however, the Applicable Margin included therein, if any) over (ii) the amount of
interest (as reasonably determined by such Lender) that would have accrued to
such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank Eurodollar market. A certificate as
to any amounts payable pursuant to this Section submitted to a Borrower by any
Lender shall be conclusive in the absence of manifest error. This covenant shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

          2.18 ILLEGALITY. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Base Rate Loans to Eurodollar Loans shall forthwith be canceled and (b)
such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be
converted automatically to Base Rate Loans on the respective last days of the
then current Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan to a
Borrower occurs on a day which is not the last day of the then current Interest
Period with respect thereto, such Borrower shall pay to such Lender such
amounts, if any, as may be required pursuant to Section 2.17.

          2.19 CHANGE OF LENDING OFFICE. Each Lender agrees that, upon the
occurrence of any event that it knows to give rise to the operation of Section
2.15, 2.16(a) or 2.18 with respect to such Lender, it will use all commercially
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event, or to
assign its rights and obligations hereunder with respect to such Loans to
another of its offices, branches or affiliates with the object of avoiding the
consequences of such event, or to assign its rights and obligations hereunder
with respect to such Loans to another of its offices, branches or affiliates,
with the object of avoiding the consequences of such event; PROVIDED, that such
designation is made on terms that, in the reasonable sole judgment of such
Lender, cause such Lender and its lending office(s) to suffer no economic, legal
or regulatory disadvantage, and provided, further, that nothing in this Section
shall affect or postpone any of the obligations of the Borrowers or the rights
of any Lender pursuant to Section 2.15, 2.16(a) or 2.18.

          2.20 REPLACEMENT OF LENDERS UNDER CERTAIN CIRCUMSTANCES. The Borrowers
shall be permitted to replace any Lender (a) that requests reimbursement for
amounts owing pursuant to Section 2.15, (b) with respect to which any Borrower
is required to pay any amounts under Section 2.16 or (c) that defaults in its
obligation to make Loans hereunder, with a replacement financial institution or
other entity; PROVIDED that (i) such replacement does not conflict with any
Requirement of Law, (ii) no Event of Default shall have occurred and be
continuing at the time of such replacement, (iii) prior to any such replacement,
such Lender shall have taken no action under Section 2.19 so as to eliminate the
continued need for payment of amounts owing pursuant to Section 2.15 or 2.16,
(iv) the replacement financial institution or other entity shall purchase, at
par, all Loans and other amounts owing to such replaced Lender on or prior to
the date of replacement, (v) each Borrower shall be liable to such replaced
Lender under Section 2.17 (as though Section 2.17 were applicable) if any
Eurodollar Loan to such Borrower owing to such

<Page>

                                                                              32

replaced Lender shall be purchased other than on the last day of the Interest
Period relating thereto, (vi) the replacement financial institution or other
entity, if not already a Lender, shall be reasonably satisfactory to the
Administrative Agent, (vii) the replaced Lender and replacement Lender shall be
obligated to make such replacement in accordance with the provisions of Section
10.6 (including, without limitation, obtaining the consents provided for
therein) (provided that the Borrowers shall be obligated to pay the registration
and processing fee referred to therein), (viii) the Borrowers shall pay all
additional amounts (if any) required pursuant to Section 2.15 or 2.16, as the
case may be, in respect of any period prior to the date on which such
replacement shall be consummated, and (ix) any such replacement shall not be
deemed to be a waiver of any rights that the Borrowers, the Administrative Agent
or any other Lender shall have against the replaced Lender.

          2.21 GUARANTY OF PAYMENT AND PERFORMANCE.

          (a) GUARANTY BY WHITE MOUNTAINS OF FUND AMERICAN'S OBLIGATIONS. White
Mountains (being referred to herein in its capacity as guarantor as a
"GUARANTOR") hereby guarantees (such guaranty being hereinafter referred to as
the "WHITE MOUNTAINS GUARANTY") to the Lenders and the Administrative Agent the
full and punctual payment when due (whether at stated maturity, by required
pre-payment, by acceleration or otherwise) of all of the obligations of Fund
American hereunder and under the other Loan Documents (including the principal
of the Loans advanced to Fund American, all Reimbursement Obligations of Fund
American in respect of Letters of Credit, and all interest, fees, expenses,
indemnities and other amounts payable by Fund American hereunder), including all
such which would become due but for the operation of the automatic stay pursuant
to Section 362(a) of the Federal Bankruptcy Code and the operation of Section
502(b) of the Federal Bankruptcy Code. The White Mountains Guaranty is an
absolute, unconditional and continuing guaranty of the full and punctual payment
and performance of all such obligations of Fund American hereunder and under the
other Loan Documents, and not of their collectibility only and is in no way
conditioned upon any requirement that the Administrative Agent or any Lender
first attempt to collect any of Fund American's obligations from Fund American
or resort to any other means of obtaining payment. Should an Event of Default
occur with respect to the payment or performance of any such obligations of Fund
American, the obligations of White Mountains under the White Mountains Guaranty
with respect to such obligations in default shall, upon demand by the
Administrative Agent, become immediately due and payable to the Administrative
Agent, for the benefit of the Lenders and the Administrative Agent, without
demand or notice of any nature, all of which are expressly waived by White
Mountains. Payments by White Mountains in respect of the White Mountains
Guaranty may be required by the Administrative Agent on any number of occasions.
All payments by White Mountains in respect of the White Mountains Guaranty shall
be made to the Administrative Agent, in the manner and at the place of payment
specified hereunder, for the account of the Lenders and the Administrative
Agent.

          (b) GUARANTY BY FUND AMERICAN OF WHITE MOUNTAINS' OBLIGATIONS. Fund
American (being referred to herein in its capacity as guarantor as a "GUARANTOR"
and together with White Mountains, in its capacity as a guarantor, as the
"GUARANTORS") hereby guarantees (such guaranty being hereinafter referred to as
the "FUND AMERICAN GUARANTY" and together with the White Mountains Guaranty as
the "GUARANTEES" and individually as a "GUARANTY") to the Lenders and the
Administrative Agent the full and punctual payment when due (whether at stated

<Page>

                                                                              33

maturity, by required pre-payment, by acceleration or otherwise) of all of the
principal of the Loans advanced to White Mountains, all Reimbursement
Obligations of White Mountains in respect of Letters of Credit and all interest
payable by White Mountains hereunder, including all such which would become due
but for the operation of the automatic stay pursuant to Section 362(a) of the
Federal Bankruptcy Code and the operation of Section 502(b) of the Federal
Bankruptcy Code. The Fund American Guaranty is an absolute, unconditional and
continuing guaranty of the full and punctual payment and performance of all of
White Mountains' obligations, PROVIDED THAT, unless (a) White Mountains is the
subject of a voluntary or involuntary proceeding under federal or state
bankruptcy, insolvency or similar law or (b) demand first being made on White
Mountains is not otherwise required by the terms of the Certificate of
Designation, Fund American's obligations in respect of the Fund American
Guaranty are conditioned on demand having been made on White Mountains for the
payment of White Mountains' obligations (the "Demand Requirement"). Payments by
Fund American in respect of the Fund American Guaranty may be required by the
Administrative Agent on any number of occasions. All payments by Fund American
in respect of the Fund American Guaranty shall be made to the Administrative
Agent, in the manner and at the place of payment specified hereunder, for the
account of the Lenders and the Administrative Agent.

          (c) AGREEMENT TO PAY ENFORCEMENT COSTS, ETC. Each of the Guarantors
further agrees, as the principal obligor and not as a guarantor only, to pay to
the Administrative Agent, on demand, all costs and expenses (including court
costs and legal expenses) incurred or expended by the Administrative Agent or
any Lender in connection with its Guaranty and the enforcement thereof, together
with interest on amounts recoverable under this Section 2.21(c) from the time
when such amounts become due until payment, whether before or after judgment, at
the rate of interest for overdue principal set forth in this Agreement, PROVIDED
THAT if such interest exceeds the maximum amount permitted to be paid under
applicable law, then such interest shall be reduced to such maximum permitted
amount.

          (d) WAIVERS BY GUARANTORS; LENDERS' FREEDOM TO ACT. Subject to the
Demand Requirement, to the fullest extent permitted by applicable law, each of
the Guarantors agrees that the obligations that it has guaranteed hereunder will
be paid and performed strictly in accordance with their respective terms,
regardless of any law, regulation or order now or hereafter in effect in any
jurisdiction affecting any of such terms or the rights of the Administrative
Agent or any Lender with respect thereto. Subject to the Demand Requirement, to
the fullest extent permitted by applicable law, each of the Guarantors waives
promptness, diligences, presentment, demand, protest, notice of acceptance,
notice of any obligations incurred and all other notices of any kind, all
defenses which may be available by virtue of any valuation, stay, moratorium law
or other similar law now or hereafter in effect, any right to require the
marshalling of assets of either of the Borrowers or any other entity or other
person primarily or secondarily liable with respect to any of the obligations,
and all suretyship defenses generally. Without limiting the generality of the
foregoing, but subject to the Demand Requirement, each of the Guarantors agrees
to the provisions of any instrument evidencing or otherwise executed in
connection with any obligation and agrees, to the fullest extent permitted by
applicable law, that its obligations in respect of its Guaranty shall not be
released or discharged, in whole or in part, or otherwise affected by (i) the
failure of the Administrative Agent or any Lender to assert any claim or demand
or to enforce any right or remedy against the Company or any other entity or
other person primarily or secondarily liable with respect to any of the
obligations; (ii) any extensions, compromise,

<Page>

                                                                              34

refinancing, consolidation or renewals of any obligation; (iii) any change in
the time, place or manner of payment of any of the obligations or any
rescissions, waivers, compromise, refinancing, consolidation or other amendments
or modifications of any of the terms or provisions of this Agreement or the
other Loan Documents or any other agreement evidencing or otherwise executed in
connection with any of the obligations, (iv) the addition, substitution or
release of any entity or other person primarily or secondarily liable for any
obligation; (v) the adequacy of any rights which the Administrative Agent or any
Lender may have against any means of obtaining repayment of any of the
obligations; or (vi) any other act or omission which might in any manner or to
any extent vary the risk of either of the Guarantors or otherwise operate as a
release or discharge of either of the Guarantors, all of which may be done
without notice to either of the Guarantors. Subject to the Demand Requirement,
to the fullest extent permitted by law, each of the Guarantors hereby expressly
waives any and all rights or defenses arising by reason of (A) any "one action"
or "anti-deficiency" law which would otherwise prevent the Administrative Agent
or any Lender from bringing any action, including any claim for a deficiency, or
exercising any other right or remedy (including any right of set-off), against
either of the Guarantors before or after the Administrative Agent's or such
Lender's commencement or completion of any foreclosure action, whether
judicially, by exercise of power of sale or otherwise, or (B) any other law
which in any other way would otherwise require any election of remedies by the
Administrative Agent or any Lender.

          (e) UNENFORCEABILITY OF OBLIGATIONS AGAINST THE BORROWERS. If for any
reason either of the Borrowers has no legal existence or is under no legal
obligation to discharge any of its obligations under this Agreement or under the
other Loan Documents guaranteed by a Guarantor, or if any of such obligations
have become irrecoverable from either of the Borrowers by reason of such
Borrower's bankruptcy or reorganization or by other operation of law or for any
other reason, the Guarantees shall, to the fullest extent permitted by
applicable law, nevertheless be binding on each of the Guarantors to the same
extent as if the affected Guarantor at all times had been the principal obligor
on all such obligations subject to the Demand Requirement. In the event that
acceleration of the time for payment of any of the guaranteed obligations of the
Borrowers under this Agreement or the other Loan Documents is stayed upon the
insolvency, bankruptcy or reorganization of either the Borrowers, or for any
other reason, all such obligations otherwise subject to acceleration under the
terms of this Agreement and the other Loan Documents or any other agreement
evidencing or otherwise executed in connection with any such obligation shall,
subject to the Demand Requirement, be immediately due and payable by the
applicable Guarantor

          (f) SUBROGATION. Until the final payment and performance in full of
all of the obligations of the Borrowers under this Agreement and the other Loan
Documents, neither of the Guarantors shall exercise any rights against the
Borrowers arising as a result of payment by such Guarantor in respect of its
Guaranty, by way of subrogation, reimbursement, restitution, contribution or
otherwise, and will not prove any claim in competition with the Administrative
Agent or any Lender in respect of any payment hereunder in any bankruptcy,
insolvency or reorganization case or proceedings of any nature and such
Guarantor will not claim any setoff, recoupment or counterclaim against the
applicable Borrower in respect of any liability of such Guarantor to the
applicable Borrower.

                                                                              35

          (g)   PROVISIONS SUPPLEMENTAL. The provisions of this Section 2.21
shall be supplemental to and not in derogation of any other rights and remedies
of the Lenders and the Administrative Agent under this Agreement, the other Loan
Documents and any separate agreement which the Administrative Agent may at any
time and from time to time enter into with either of the Guarantors for the
benefit of the Lenders and the Administrative Agent.

          (h)   FURTHER ASSURANCES. Each of the Guarantors agrees that it will
from time to time, at the request of the Administrative Agent, do all such
things and execute all such documents as the Administrative Agent may reasonably
request to give full effect to the Guarantee of such Guarantor and to preserve
the rights and powers of the Lenders and the Administrative Agent in respect of
such Guarantee. Each of the Guarantors acknowledges and confirms that it has
established its own adequate means of obtaining from the applicable Borrower on
a continuing basis all information desired by such Guarantor concerning the
financial condition of the applicable Borrower and that such Guarantor will look
to the applicable Borrower and not to the Administrative Agent or any Lender in
order for such Guarantor to keep adequately informed of changes in the
applicable Borrower's financial condition.

          (i) SUCCESSORS AND ASSIGNS. The Guarantee of each Guarantor shall be
binding upon such Guarantor, its successors and assigns, and shall inure to the
benefit of the Administrative Agent and the Lenders and their respective ,
permitted transferees and permitted assigns. Without limiting the generality of
the foregoing sentence, each Lender may, to the extent permitted by Section
10.6, assign or otherwise transfer this Agreement, the other Loan Documents or
any other agreement or note held by it evidencing or otherwise executed in
connection with the guaranteed obligations, or sell participations in any
interest therein, to any other entity or other person, and such other entity or
other person shall, to the extent provided by Section 10.6, thereupon become
vested, to the extent set forth in the agreement evidencing such assignment,
transfer or participation, with all the rights in respect thereof granted to
such Lender herein, all in accordance with Section 10.6 of this Agreement.

SECTION 3 LETTERS OF CREDIT

          3.1 L/C COMMITMENT. (a) Subject to the terms and conditions hereof,
each Issuing Lender, in reliance on the agreements of the other Lenders set
forth in Section 3.4(a), agrees to issue letters of credit ("LETTERS OF CREDIT")
for the account of either of the Borrowers on any Business Day during the
Revolving Credit Commitment Period in such form as may be approved from time to
time by the Issuing Lender; PROVIDED, that the Issuing Lender shall not issue
any Letter of Credit if, after giving effect to such issuance, (i) the L/C
Obligations would exceed the L/C Commitment or (ii) the aggregate amount of the
Available Revolving Credit Commitments would be less than zero. Each Letter of
Credit shall (i) be denominated in Dollars and (ii) expire no later than the
earlier of (x) the first anniversary of its date of issuance and (y) the date
which is five Business Days prior to the Revolving Credit Termination Date,
provided that any Letter of Credit with a one-year term may provide for the
renewal thereof for additional one-year periods (which shall in no event extend
beyond the date referred to in clause (y) above).

<Page>

                                                                              36

          (b) No Issuing Lender shall at any time be obligated to issue any
Letter of Credit hereunder if such issuance would conflict with, or cause the
Issuing Lender or any L/C Participant to exceed any limits imposed by, any
applicable Requirement of Law.

          3.2 PROCEDURE FOR ISSUANCE OF LETTER OF CREDIT. Each Borrower may from
time to time request that an Issuing Lender issue a Letter of Credit by
delivering to the Issuing Lender (with a copy to the Administrative Agent) at
its address for notices specified herein an Application therefor, completed to
the satisfaction of such Issuing Lender, and such other certificates, documents
and other papers and information as such Issuing Lender may request. Upon
receipt of any Application, such Issuing Lender will process such Application
and the certificates, documents and other papers and information delivered to it
in connection therewith in accordance with its customary procedures and shall
promptly issue the Letter of Credit requested thereby by issuing the original of
such Letter of Credit to the beneficiary thereof or as otherwise may be agreed
to by such Issuing Lender and the relevant Borrower (but in no event shall any
Issuing Lender be required to issue any Letter of Credit earlier than three
Business Days after its receipt of the Application therefor and all such other
certificates, documents and other papers and information relating thereto).
Promptly after issuance by an Issuing Lender of a Letter of Credit, such Issuing
Lender shall furnish a copy of such Letter of Credit to the requesting Borrower.
Each Issuing Lender shall, within three days of such issuance, give notice to
the Administrative Agent of the issuance of each Letter of Credit issued by such
Issuing Lender (including the amount thereof). Upon the written request of any
Lender, the Administrative Agent will, within three Business Days of such
request, inform such Lender of the aggregate drawable amount of all outstanding
Letters of Credit issued to the Borrowers on the date of such request.

          3.3 FEES AND OTHER CHARGES. (a) Each Borrower will pay to the
Administrative Agent, for the account of the Lenders, a fee on the aggregate
drawable amount of all outstanding Letters of Credit issued for its account at a
per annum rate equal to the Applicable Margin then in effect with respect to
Eurodollar Loans, to be shared ratably among the Lenders in accordance with
their respective Revolving Credit Percentages and payable quarterly in arrears
on each L/C Fee Payment Date after the issuance date. In addition, each Borrower
shall pay to the relevant Issuing Lender for its own account a fronting fee on
the aggregate drawable amount of all outstanding Letters of Credit issued by
such Issuing Lender for such Borrower's account at a rate to be agreed upon by
such Borrower and such Issuing Lender, payable quarterly in arrears on each L/C
Fee Payment Date after the date of issuance of such Letter of Credit.

          (b) In addition to the foregoing fees, each Borrower shall pay or
reimburse each Issuing Lender for such normal and customary costs and expenses
as are incurred or charged by such Issuing Lender in issuing, negotiating,
effecting payment under, amending or otherwise administering any Letter of
Credit issued for the account of such Borrower.

          3.4 L/C PARTICIPATIONS. (a) Each Issuing Lender irrevocably agrees to
grant and hereby grants to each L/C Participant, and, to induce each Issuing
Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably
agrees to accept and purchase and hereby accepts and purchases from each Issuing
Lender, on the terms and conditions hereinafter stated, for such L/C
Participant's own account and risk, an undivided interest equal to such L/C
Participant's Revolving Credit Percentage in each Issuing Lender's obligations
and rights under

<Page>

                                                                              37

each Letter of Credit issued by such Issuing Lender hereunder and the amount of
each draft paid by such Issuing Lender thereunder. Each L/C Participant
unconditionally and irrevocably agrees with each Issuing Lender that, if a draft
is paid under any Letter of Credit issued by such Issuing Lender for which such
Issuing Lender is not reimbursed in full by the Borrowers in accordance with the
terms of this Agreement, such L/C Participant shall pay to such Issuing Lender
upon demand at the Issuing Lender's address for notices specified herein an
amount equal to such L/C Participant's Revolving Credit Percentage of the amount
of such draft, or any part thereof, that is not so reimbursed.

          If any amount required to be paid by any L/C Participant to an Issuing
Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any
payment made by such Issuing Lender under any Letter of Credit is paid to such
Issuing Lender within three Business Days after the date such payment is due,
such L/C Participant shall pay to such Issuing Lender on demand an amount equal
to the product of (i) such amount, times (ii) the daily average Federal Funds
Effective Rate during the period from and including the date such payment is
required to the date on which such payment is immediately available to such
Issuing Lender, times (iii) a fraction the numerator of which is the number of
days that elapse during such period and the denominator of which is 365 (or, in
the case of a leap year, 366).

          (b) If any such amount required to be paid by any L/C Participant
pursuant to Section 3.4(a) is not made available to such Issuing Lender by such
L/C Participant within three Business Days after the date such payment is due,
such Issuing Lender shall be entitled to recover from such L/C Participant, on
demand, such amount with interest thereon calculated from such due date at the
rate per annum applicable to Base Rate Loans. A certificate of such Issuing
Lender submitted to any L/C Participant with respect to any such amounts owing
under this Section shall be conclusive in the absence of manifest error.

          (c) Whenever, at any time after an Issuing Lender has made payment
under any Letter of Credit and has received from any L/C Participant its PRO
RATA share of such payment in accordance with Section 3.4(a), such Issuing
Lender receives any payment related to such Letter of Credit (whether directly
from the Borrowers or otherwise, including proceeds of collateral applied
thereto by the Issuing Lender), or any payment of interest on account thereof,
such Issuing Lender will distribute to such L/C Participant its PRO RATA share
thereof; PROVIDED, HOWEVER, that in the event that any such payment received by
such Issuing Lender shall be required to be returned by such Issuing Lender,
such L/C Participant shall return to such Issuing Lender the portion thereof
previously distributed by such Issuing Lender to it.

          3.5 REIMBURSEMENT OBLIGATION OF THE BORROWERS. Each of the Borrowers
agree to reimburse each Issuing Lender, on the next Business Day after each date
on which such Issuing Lender notifies such Borrower of the date and amount of a
draft presented under any Letter of Credit issued for the account of such
Borrower and paid by the Issuing Lender, for the amount of (a) such draft so
paid and (b) any taxes, fees, charges or other costs or expenses incurred by the
Issuing Lender in connection with such payment (the amounts described in the
foregoing clauses (a) and (b) in respect of any drawing, collectively, the
"PAYMENT AMOUNT"). Each such payment shall be made to such Issuing Lender at its
address for notices specified herein in lawful money of the United States of
America and in immediately available funds. Interest shall be payable on each
Payment Amount from the date of the applicable drawing until payment in full at
the rate

<Page>

                                                                              38

set forth in (i) until the second Business Day following the date of the
applicable drawing, Section 2.11(b) and (ii) thereafter, Section 2.11(c). Each
drawing under any Letter of Credit issued for the account of a Borrower shall
(unless an event of the type described in clause (i) or (ii) of Section 8(f)
shall have occurred and be continuing with respect to the Borrowers, in which
case the procedures specified in Section 3.4 for funding by L/C Participants
shall apply) constitute a request by such Borrower to the Administrative Agent
for a borrowing pursuant to Section 2.2 of Base Rate Loans or, at the option of
the Administrative Agent and the Swing Line Lender in their sole discretion, a
borrowing pursuant to Section 2.4 of Swing Line Loans, in the amount of such
drawing. The Borrowing Date with respect to such borrowing shall be the first
date on which a borrowing of Revolving Credit Loans (or, if applicable, Swing
Line Loans) could be made, pursuant to Section 2.2 (or, if applicable, Section
2.4), if the Administrative Agent had received a notice of such borrowing at the
time the Administrative Agent receives notice from the relevant Issuing Lender
of such drawing under such Letter of Credit.

          3.6 OBLIGATIONS ABSOLUTE. Each Borrower's obligations under this
Section 3 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment that such
Borrower may have or have had against any Issuing Lender, any beneficiary of a
Letter of Credit or any other Person. Each Borrower also agrees with the Issuing
Lender that the Issuing Lender shall not be responsible for, and its
Reimbursement Obligations under Section 3.5 shall not be affected by, among
other things, the validity or genuineness of documents or of any endorsements
thereon, even though such documents shall in fact prove to be invalid,
fraudulent or forged, or any dispute between or among such Borrower and any
beneficiary of any Letter of Credit or any other party to which such Letter of
Credit may be transferred or any claims whatsoever of such Borrower against any
beneficiary of such Letter of Credit or any such transferee. No Issuing Lender
shall be liable for any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however transmitted, in
connection with any Letter of Credit, except for errors or omissions found by a
final and nonappealable decision of a court of competent jurisdiction to have
resulted from the gross negligence or willful misconduct of such Issuing Lender.
Each Borrower agrees that any action taken or omitted by an Issuing Lender under
or in connection with any Letter of Credit issued by it for the account of such
Borrower or the related drafts or documents, if done in the absence of gross
negligence or willful misconduct and in accordance with the standards of care
specified in the Uniform Commercial Code in effect in the State of New York (the
"UCC") or, if applicable to such Letter of Credit, the Uniform Customs and
Practice for Documentary Credits as published by the International Chamber of
Commerce most recently at the time of issuance of any Letter of Credit (the
"UCP"), shall be binding on such Borrower and shall not result in any liability
of such Issuing Lender to such Borrower.

          3.7 LETTER OF CREDIT PAYMENTS. If any draft shall be presented for
payment under any Letter of Credit, the relevant Issuing Lender shall promptly
notify the Borrowers of the date and amount thereof. The responsibility of the
relevant Issuing Lender to the Borrowers in connection with any draft presented
for payment under any Letter of Credit, in addition to any payment obligation
expressly provided for in such Letter of Credit issued by the Issuing Lender,
shall be limited to determining that the documents (including each draft)
delivered under such Letter of Credit in connection with such presentment appear
on their face to be in conformity with such Letter of Credit.

          3.8 APPLICATIONS. To the extent that any provision of any Application
related to any Letter of Credit is inconsistent with the provisions of this
Section 3, the provisions of this Section 3 shall apply.

SECTION 4 REPRESENTATIONS AND WARRANTIES

          To induce the Administrative Agent and the Lenders to enter into this
Agreement and to make the Loans and issue or participate in the Letters of
Credit, the Borrowers hereby jointly and severally represent and warrant to the
Administrative Agent and each Lender that:

          4.1 FINANCIAL CONDITION. The audited consolidated balance sheet of
White Mountains and its consolidated Subsidiaries, as at December 31, 2002 and
the related consolidated statements of income and of cash flows for the fiscal
year ended on such date, reported on by and accompanied by unqualified reports
from PricewaterhouseCoopers LLP, present fairly in all material respects the
consolidated financial condition of White Mountains and its consolidated
Subsidiaries, as at such date, and the consolidated results of their operations
and their consolidated cash flows for such fiscal year then ended in accordance
with GAAP applied consistently throughout the periods involved (except as
approved by the aforementioned firm of accountants and disclosed therein). The
unaudited consolidated balance sheet of White Mountains and its consolidated
Subsidiaries, as of and for the fiscal quarters ended March 31, 2003 and June
30, 2003, and the related unaudited consolidated statements of income and cash
flows for such fiscal quarters ended on such dates, present fairly in all
material respects the consolidated financial condition of White Mountains and
its consolidated Subsidiaries as at such dates, and the consolidated results of
their operations and their consolidated cash flows for the fiscal quarters then
ended in accordance with GAAP applied consistently throughout the periods
involved (except (x) as approved by the aforementioned firms of accountants and
disclosed therein or (y) for normal year-end audit adjustments and the absence
of footnotes).

          4.2 NO CHANGE. Up to and including the Closing Date, since December
31, 2002 there has been no development or event that has had or could reasonably
be expected to have a Material Adverse Effect.

          4.3 CORPORATE EXISTENCE; COMPLIANCE WITH LAW. Each of the Borrowers
and their Subsidiaries (a) is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, except to the
extent that the failure of the Subsidiaries (other than Fund American) to be so
organized, validly existing and in good standing could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect, (b) has the corporate
or other power and authority, and the legal right, to own and operate its
Property, to lease the Property it operates as lessee and to conduct the
business in which it is currently engaged, , except to the extent that the
failure to have such power, authority and legal right could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect, (c) is duly
qualified as a foreign corporation and in good standing under the laws of each
jurisdiction where its ownership, lease or operation of Property or the conduct
of its business requires such qualification, except to the extent failure to so
qualify or be in good standing could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect, and (d) is in compliance with all
Requirements of Law, including, without limitation, with respect to
environmental laws, except to the extent that

<Page>

                                                                              40

the failure to comply therewith could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect. The Guaranty by Fund American
pursuant to Section 2.21 hereof of the outstanding principal amount of any Loans
that have been advanced to White Mountains plus all Reimbursement Obligations of
White Mountains in respect of Letters of Credit that have been issued for the
account of White Mountains plus all accrued interest payable thereon by White
Mountains hereunder is not prohibited by Section 4 of the Certificate of
Designation.

          4.4 CORPORATE POWER; AUTHORIZATION; ENFORCEABLE OBLIGATIONS. Each of
the Borrowers has the corporate or other power and authority, and the legal
right, to make, deliver and perform the Loan Documents to which it is a party
and to borrow hereunder. Each of the Borrowers has taken all necessary corporate
or other action to authorize the execution, delivery and performance of the Loan
Documents to which it is a party and to authorize the borrowings on the terms
and conditions of this Agreement. No consent or authorization of, filing with,
notice to or other act by or in respect of, any Governmental Authority or any
other Person is required in connection with the borrowings hereunder or the
execution, delivery, performance, validity or enforceability of this Agreement
or any of the other Loan Documents, except consents, authorizations, filings and
notices described in Schedule 4.4, which consents, authorizations, filings and
notices have been obtained or made and are in full force and effect and except
to the extent failure to obtain any consents, authorizations, filings, and
notices could not, in the aggregate, reasonably be expected to have a Material
Adverse Effect. Each Loan Document has been duly executed and delivered on
behalf of each Borrower that is a party thereto. This Agreement constitutes, and
each other Loan Document upon execution will constitute, a legal, valid and
binding obligation of each Borrower that is a party thereto, enforceable against
each such Borrower in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally and by
general equitable principles (whether enforcement is sought by proceedings in
equity or at law) and except that, pursuant to the terms of the Berkshire
Preferred Stock, the Fund American Guaranty is subject to limitations on the
amount that may be guaranteed by Fund American hereunder (the "FUND AMERICAN
GUARANTY LIMITATIONS")

          4.5 NO LEGAL BAR. Subject to compliance with the Fund American
Guaranty Limitations, the execution, delivery and performance of this Agreement
and the other Loan Documents, the issuance of Letters of Credit, the borrowings
hereunder and the use of the proceeds thereof will not violate any Requirement
of Law or any Contractual Obligation of the Borrowers or any of their
Subsidiaries and will not result in, or require, the creation or imposition of
any Lien on any of their respective properties or revenues pursuant to any
Requirement of Law or any such Contractual Obligation, except to the extent such
violation or Lien could not, in the aggregate, reasonably be expected to have a
Material Adverse Effect.

          4.6 NO MATERIAL LITIGATION. No litigation, investigation or proceeding
of or before any arbitrator or Governmental Authority is pending or, to the
knowledge of the Borrowers, threatened by or against the Borrowers or any of
their Subsidiaries or against any of their respective properties or revenues (a)
with respect to any of the Loan Documents or any of the transactions
contemplated hereby or thereby, or (b) that could reasonably be expected to have
a Material Adverse Effect.

<Page>

                                                                              41

          4.7 OWNERSHIP OF PROPERTY; LIENS. Each of the Borrowers and their
Subsidiaries has title in fee simple to, or a valid leasehold interest in, all
its real property, and good title to, or a valid leasehold interest in, all its
other Property, and none of such Property is subject to any Lien except as
permitted by Section 7.3, except to the extent such defects in title could not,
in the aggregate, reasonably be expected to have a Material Adverse Effect.

          4.8 INTELLECTUAL PROPERTY. Each of the Borrowers and each of their
Subsidiaries owns, or is licensed to use, all Intellectual Property material to
the conduct of its business as currently conducted. No material claim has been
asserted and is pending by any Person challenging or questioning the use of any
Intellectual Property or the validity or effectiveness of any Intellectual
Property, nor do the Borrowers know of any valid basis for any such claim, other
than claims that could not, in the aggregate, reasonably be expected to have a
Material Adverse Effect. The use of Intellectual Property by the Borrowers and
their Subsidiaries does not infringe on the rights of any Person in any material
respect, except for infringements that could not, in the aggregate, reasonably
be expected to have a Material Adverse Effect.

          4.9 TAXES. Each of the Borrowers and their Subsidiaries has filed or
caused to be filed all material Federal, state and other tax returns that are
required to be filed (taking into account any applicable extensions) and has
paid all taxes shown to be due and payable on said returns or on any assessments
made against it or any of its Property and all other material taxes, fees or
other charges imposed on it or any of its Property by any Governmental Authority
(other than (i) any the amount or validity of which are currently being
contested in good faith by appropriate proceedings and with respect to which
reserves in conformity with SAP or GAAP, as applicable, have been provided on
the books of the Borrowers or their Subsidiaries, as the case may be, and (ii)
any amount the failure of which to pay could not reasonably be expected to
result in a Material Adverse Effect.; and, to the knowledge of the Borrowers, no
tax Lien has been filed, and no claim is being asserted, with respect to any
such tax, fee or other charge.

          4.10 FEDERAL REGULATIONS. No part of the proceeds of any Loans will be
used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U as now and from time to
time hereafter in effect or for any purpose that violates the provisions of the
Regulations of the Board. If requested by any Lender or the Administrative
Agent, the Borrowers will furnish to the Administrative Agent and each Lender a
statement to the foregoing effect in conformity with the requirements of FR Form
G-3 or FR Form U-1 referred to in Regulation U.

          4.11 ERISA. Except as could not reasonably be expected to result in a
Material Adverse Effect, neither a Reportable Event nor an "accumulated funding
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code. No termination of a Single Employer Plan has occurred, and no Lien
in favor of the PBGC or a Plan has arisen, during such five-year period. The
present value of all accrued benefits under each Single Employer Plan (based on
those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits by an amount which, could reasonably be expected to result in a
Material

<Page>

                                                                              42

Adverse Effect. Neither the Borrowers nor any Commonly Controlled Entity has had
a complete or partial withdrawal from any Multiemployer Plan that has resulted
or could reasonably be expected to result in a material liability to the
Borrowers under ERISA. Except as could not reasonably be expected to result in a
Material Adverse Effect, no such Multiemployer Plan is in Reorganization or
Insolvent.

          4.12 INVESTMENT COMPANY ACT; OTHER REGULATIONS. Neither of the
Borrowers is an "investment company" within the meaning of the Investment
Company Act of 1940, as amended. Neither of the Borrowers is subject to
regulation under any Requirement of Law (other than Regulation X of the Board
and the Certificate of Designation) which limits its ability to incur
Indebtedness hereunder.

          4.13 USE OF PROCEEDS. 4.13 The proceeds of the Loans and the Letters
of Credit shall not be used for purposes other than working capital and general
corporate purposes of the Borrowers, including, without limitation, (a)
investments in or acquisitions of businesses or entities, provided that the
aggregate principal amount of Loans outstanding at any time that are used to
finance investments or acquisitions, other than investments in or acquisitions
of businesses or entities engaged in a Principal Business, shall not exceed
$50,000,000, (b) refinancings of outstanding indebtedness, if any, under Fund
American's existing credit facility in connection with that certain Amended and
Restated Credit Agreement dated as of October 30, 2002 among Fund American, Fund
American Enterprises Holdings, Inc., the lenders party thereto and Lehman
Commercial Paper Inc., as Administrative Agent (and any existing letters of
credit under such facility may become Letters of Credit hereunder) and (c)
payment of fees and expenses in connection with this Agreement.

          4.14 ACCURACY OF INFORMATION, ETC. No statement or information
contained in the Confidential Information Memorandum or any other document,
certificate or statement furnished to the Administrative Agent or the Lenders or
any of them, by or on behalf of either of the Borrowers for use in connection
with the transactions contemplated by this Agreement or the other Loan
Documents, taken as a whole contained as of the date such statement,
information, document or certificate was so furnished (or, in the case of the
Confidential Information Memorandum, as of the date of this Agreement), any
untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements contained therein not misleading. The
projections and pro forma financial information contained in the materials
referenced above are based upon good faith estimates and assumptions believed by
management of the Borrowers to be reasonable at the time made, it being
recognized by the Lenders that such financial information as it relates to
future events is not to be viewed as fact and that actual results during the
period or periods covered by such financial information may differ from the
projected results set forth therein by a material amount.

          4.15 INSURANCE REGULATORY MATTERS. No License of any Insurance
Subsidiary, the loss of which could reasonably be expected to have a Material
Adverse Effect, is the subject of a proceeding for suspension or revocation. To
the knowledge of the Borrowers, there is no sustainable basis for such
suspension or revocation, and no such suspension or revocation has been
threatened by any Governmental Authority.

                                                                              43

          4.16. INDEBTEDNESS AND LIENS. As of the Closing Date, (i) no
Subsidiary (other than Fund American) of either of the Borrowers had outstanding
any Indebtedness of such Subsidiary that was created, incurred or assumed after
June 30, 2003, except Indebtedness that would have been permitted by Section 7.2
(without giving effect to the Indebtedness permitted by Section 7.2(a)) if
created, incurred or assumed by such Subsidiary on the Closing Date and (ii)
there does not exist (a) any Lien that was created, incurred or assumed after
June 30, 2003, upon any stock or indebtedness of any Subsidiary to secure any
Debt of the Borrowers or any of their Subsidiaries or any other person (other
than the obligations hereunder) or (b) any Lien that was created, incurred or
assumed after June 30, 2003, upon any other Property, to secure any Debt of the
Borrowers or any of their Subsidiaries or any other person (other than the
obligations hereunder), except, in the case of (a) or (b), Liens that would have
been permitted by Section 7.3 hereof (without giving effect to the Liens that
would have been permitted by Section 7.3(a)(x)) if so created, incurred or
assumed on the Closing Date.

for honor shall not have occurred at the time of an

<Page>

                                                                              54

acceleration pursuant to this paragraph, such Borrower shall at such time
deposit in a cash collateral account opened by the Administrative Agent an
amount equal to the aggregate then undrawn and unexpired amount of such Letters
of Credit. Amounts held in such cash collateral account shall be applied by the
Administrative Agent to the payment of drafts drawn under such Letters of
Credit, and the unused portion thereof after all such Letters of Credit shall
have expired or been fully drawn upon, if any, shall be applied to repay other
obligations of the Borrowers hereunder and under the other Loan Documents. After
all such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations of
the Borrowers hereunder and under the other Loan Documents shall have been paid
in full, the balance, if any, in such cash collateral account shall be returned
to the applicable Borrower (or such other Person as may be lawfully entitled
thereto).

SECTION 9 THE ADMINISTRATIVE AGENT

          9.1 APPOINTMENT. Each Lender hereby irrevocably designates and
appoints the Administrative Agent as the agent of such Lender under this
Agreement and the other Loan Documents, and each Lender irrevocably authorizes
the Administrative Agent, in such capacity, to take such action on its behalf
under the provisions of this Agreement and the other Loan Documents and to
exercise such powers and perform such duties as are expressly delegated to the
Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent.

          9.2 DELEGATION OF DUTIES. The Administrative Agent may execute any of
its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

          9.3 EXCULPATORY PROVISIONS. Neither the Administrative Agent nor any
of its officers, directors, employees, agents, attorneys-in-fact or affiliates
shall be (i) liable for any action lawfully taken or omitted to be taken by it
or such Person under or in connection with this Agreement or any other Loan
Document (except to the extent that any of the foregoing are found by a final
and nonappealable decision of a court of competent jurisdiction to have resulted
from its or such Person's own gross negligence or willful misconduct) or (ii)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by either of the Borrowers or any officer
thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Administrative Agent under or in connection with, this
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document or for any failure of either of the Borrowers that is a party thereto
to perform its obligations hereunder or thereunder. The

<Page>

                                                                              55

Administrative Agent shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of either of the
Borrowers.

          9.4 RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent shall
be entitled to rely, and shall be fully protected in relying, upon any
instrument, writing, resolution, notice, consent, certificate, affidavit,
letter, telecopy, telex or teletype message, statement, order or other document
or conversation believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel (including, without limitation, counsel to the
Borrowers), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent may deem and treat the payee of
any Note as the owner thereof for all purposes unless such Note shall have been
transferred in accordance with Section 10.6 and all actions required by such
Section in connection with such transfer shall have been taken. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Majority Lenders (or, if so specified
by this Agreement, all Lenders) as it deems appropriate or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense that may be incurred by it by reason of taking or continuing to take any
such action. The Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Majority Lenders (or, if so
specified by this Agreement, all Lenders or any other instructing group of
Lenders specified by this Agreement), and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

          9.5 NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Administrative Agent shall have received notice from a
Lender or the Borrowers referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default". In the
event that the Administrative Agent shall receive such a notice, the
Administrative Agent shall give notice thereof to the Lenders. The
Administrative Agent shall take such action with respect to such Default or
Event of Default as shall be reasonably directed by the Majority Lenders (or, if
so specified by this Agreement, all Lenders or any other instructing group of
Lenders specified by this Agreement); provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Lenders.

          9.6 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS. Each
Lender expressly acknowledges that neither the Administrative Agent nor any of
its respective officers, directors, employees, agents, attorneys-in-fact or
affiliates have made any representations or warranties to it and that no act by
the Administrative Agent hereafter taken, including any review of the affairs of
either of the Borrowers or any affiliate of either of the Borrowers, shall be
deemed to constitute any representation or warranty by the Administrative Agent
to any Lender. Each Lender represents to the Administrative Agent that it has,
independently and without reliance upon the Administrative Agent or any other
Lender, and based on such documents and

<Page>

                                                                              56

information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrowers and their affiliates and made
its own decision to make its Loans hereunder and enter into this Agreement. Each
Lender also represents that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrowers and their
affiliates. Except for notices, reports and other documents expressly required
to be furnished to the Lenders by the Administrative Agent hereunder, the
Administrative Agent shall have no duty or responsibility to provide any Lender
with any credit or other information concerning the business, operations,
property, condition (financial or otherwise), prospects or creditworthiness of
either of the Borrowers or any affiliate of either of the Borrowers that may
come into the possession of the Administrative Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates.

          9.7 INDEMNIFICATION. The Lenders agree to indemnify the Administrative
Agent in its capacity as such (to the extent not reimbursed by the Borrowers and
without limiting the obligation of the Borrowers to do so), ratably according to
their respective Revolving Credit Percentages in effect on the date on which
indemnification is sought under this Section (or, if indemnification is sought
after the date upon which the Commitments shall have terminated and the Loans
shall have been paid in full, ratably in accordance with such Revolving Credit
Percentages immediately prior to such date), for, and to hold the Administrative
Agent harmless from and against, any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever that may at any time (including, without limitation, at
any time following the payment of the Loans) be imposed on, incurred by or
asserted against the Administrative Agent in any way relating to or arising out
of, the Commitments, this Agreement, any of the other Loan Documents or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the
Administrative Agent under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements that are found by a final and nonappealable
decision of a court of competent jurisdiction to have resulted from the
Administrative Agent's gross negligence or willful misconduct. The agreements in
this Section shall survive the payment of the Loans and all other amounts
payable hereunder.

          9.8 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. The
Administrative Agent and its Affiliates may make loans to, accept deposits from,
hold equity interests in and generally engage in any kind of business with
either of the Borrowers or their Affiliates as though the Administrative Agent
were not an Administrative Agent. With respect to its Loans made or renewed by
it and with respect to any Letter of Credit issued or participated in by it, the
Administrative Agent shall have the same rights and powers under this Agreement
and the other Loan Documents as any Lender and may exercise the same as though
it were not an Administrative Agent, and the terms "Lender" and "Lenders" shall
include the Administrative Agent in its individual capacity.

<Page>

                                                                              57

          9.9 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 15 days' notice to the Lenders and the
Borrowers. If the Administrative Agent shall resign as Administrative Agent
under this Agreement and the other Loan Documents, then the Majority Lenders
shall appoint from among the Lenders a successor agent for the Lenders, which
successor agent shall (unless an Event of Default under Section 8(a) or 8 (f)
with respect to a Borrower shall have occurred and be continuing) be subject to
approval by the Borrowers (which approval shall not be unreasonably withheld or
delayed), whereupon such successor agent shall succeed to the rights, powers and
duties of the Administrative Agent, and the term "Administrative Agent" shall
mean such successor agent effective upon such appointment and approval, and the
former Administrative Agent's rights, powers and duties as Administrative Agent
shall be terminated, without any other or further act or deed on the part of
such former Administrative Agent or any of the parties to this Agreement or any
holders of the Loans. If no successor agent has accepted appointment as
Administrative Agent by the date that is 15 days following a retiring
Administrative Agent's notice of resignation, the retiring Administrative
Agent's resignation shall nevertheless thereupon become effective, and the
Lenders shall assume and perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Majority Lenders appoint a successor
agent as provided for above. After the retiring Administrative Agent's
resignation as Administrative Agent, the provisions of this Section 9 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Administrative Agent under this Agreement and the other Loan Documents.

          9.10 AUTHORIZATION TO RELEASE LIENS AND GUARANTEES. The Administrative
Agent is hereby irrevocably authorized by each of the Lenders to effect any
release of guarantee obligations contemplated by Section 10.15.

          9.11 THE JOINT LEAD ARRANGERS AND THE SYNDICATION AGENT. The Joint
Lead Arrangers and the Syndication Agent, in their respective capacities as
such, shall have no duties or responsibilities, and shall incur no liability,
under this Agreement and the other Loan Documents.

SECTION 10 MISCELLANEOUS

          10.1 AMENDMENTS AND WAIVERS. Neither this Agreement or any other Loan
Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this Section 10.1. The
Majority Lenders and each Borrower party to the relevant Loan Document may, or
(with the written consent of the Majority Lenders) the Administrative Agent and
each Borrower party to the relevant Loan Document may, from time to time, (a)
enter into written amendments, supplements or modifications hereto and to the
other Loan Documents (including amendments and restatements hereof or thereof)
for the purpose of adding any provisions to this Agreement or the other Loan
Documents or changing in any manner the rights of the Lenders or of the
Borrowers hereunder or thereunder or (b) waive, on such terms and conditions as
may be specified in the instrument of waiver, any of the requirements of this
Agreement or the other Loan Documents or any Default or Event of Default and its
consequences; PROVIDED, HOWEVER, that no such waiver and no such amendment,
supplement or modification shall:

<Page>

                                                                              58

               (i) forgive or reduce the principal amount or extend the final
     scheduled date of maturity of any Loan or Reimbursement Obligation, reduce
     the stated rate of any interest or fee payable hereunder or extend the
     scheduled date of any payment thereof, or increase the amount or extend the
     expiration date of any Commitment of any Lender, in each case without the
     consent of each Lender directly affected thereby;

               (ii) (a) amend, modify or waive any provision of this Section
     10.1, (b) amend, modify or waive the definition of Majority Lenders, (c)
     consent to the assignment or transfer by either of the Borrowers of any of
     its rights and obligations under this Agreement and the other Loan
     Documents or (d) release either of the Borrowers from their guarantee
     obligations under the Guarantees except as provided in Section 10.15, in
     each case without the consent of all Lenders;

               (iii) amend, modify or waive any provision of Section 9 without
     the consent of the Administrative Agent;

               (iv) amend, modify or waive any provision of Section 2.3 or 2.4
     without the written consent of the Swing Line Lender;

               (v) amend, modify or waive any provision of Section 2.14 without
     the consent of each Lender directly affected thereby;

               (vi) amend, modify or waive any provision of Section 3 without
     the consent of the Issuing Lender;

               (vii) amend, modify or waive the provisions of the definition of
     Interest Period regarding twelve month Interest Periods for Eurodollar
     Loans without the consent of each relevant Lender.

Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Borrowers, the
Lenders, the Administrative Agent and all future holders of the Loans. In the
case of any waiver, the Borrowers, the Lenders and the Administrative Agent
shall be restored to their former position and rights hereunder and under the
other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default or Event of Default, or impair any right consequent
thereon. Any such waiver, amendment, supplement or modification shall be
effected by a written instrument signed by the parties required to sign pursuant
to the foregoing provisions of this Section; PROVIDED, that delivery of an
executed signature page of any such instrument by facsimile transmission shall
be effective as delivery of a manually executed counterpart thereof.

          For the avoidance of doubt, this Agreement may be amended (or amended
and restated) with the written consent of the Majority Lenders, the
Administrative Agent and each Borrower party to each relevant Loan Document (x)
to add one or more additional credit facilities to this Agreement and to permit
the extensions of credit from time to time outstanding thereunder and the
accrued interest and fees in respect thereof to share ratably in the benefits of
this Agreement and the other Loan Documents with the Loans, the L/C Obligations
and the

<Page>

                                                                              59

accrued interest and fees in respect thereof and (y) to include appropriately
the Lenders holding such credit facilities in any determination of the Majority
Lenders.

delay in exercising, on the part of the Administrative Agent or any Lender, any
right, remedy, power or privilege hereunder or under the other Loan Documents
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right, remedy, power or privilege hereunder preclude any other or further

The rights, remedies, powers and privileges herein provided are cumulative and
not exclusive of any rights, remedies, powers and privileges provided by law.

          10.4 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations

modification to, this Agreement and the other Loan Documents and any other
documents prepared in connection herewith or therewith, and the consummation and
administration of the transactions contemplated hereby and thereby, including,
without

<Page>

                                                                              61

limitation, the reasonable fees and disbursements and other charges of counsel
to the Administrative Agent and the charges of Intralinks, (b) to pay or
reimburse each Lender and the Administrative Agent for all of their reasonable,
out-of-pocket costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, the other Loan Documents and
any such other documents, including, without limitation, the reasonable fees and
disbursements of counsel to each Lender and of counsel to the Administrative
Agent, (c) to pay, indemnify, or reimburse each Lender and the Administrative
Agent for, and hold each Lender and the Administrative Agent harmless from, any
and all recording and filing fees and any and all liabilities with respect to,
or resulting from any delay in paying, stamp, excise and other taxes, if any,
which may be payable or determined to be payable in connection with the
execution and delivery of, or consummation or administration of any of the
transactions contemplated by, or any amendment, supplement or modification of,
or any waiver or consent under or in respect of, this Agreement, the other Loan
Documents and any such other documents, and (d) to pay, indemnify or reimburse
each Lender, the Administrative Agent, and their respective affiliates, and
their respective officers, directors, shareholders, trustees, employees,
advisors, agents and controlling persons (each, an "Indemnitee") for, and hold
each Indemnitee harmless from and against any and all other liabilities,
obligations, losses, damages, claims, penalties, causes of action, judgments or
suits of any kind whatsoever and reasonable, related out-of-pocket costs and
expenses arising out of the execution, delivery, enforcement, performance and
administration of this Agreement, the other Loan Documents and any such other
documents, including, without limitation, any of the foregoing relating to the
use of proceeds of the Loans or the violation of, noncompliance with or
liability under, any environmental law applicable to the operations of the
Borrowers or any of their Subsidiaries or any of the Properties and the
reasonable, related, out-of-pocket, costs, expenses, fees and disbursements and
other charges of legal counsel in connection with claims, actions or proceedings
by any Indemnitee against the Borrowers hereunder (all the foregoing in this
clause (d), collectively, the "Indemnified Liabilities"), provided, that the
Borrowers shall have no obligation hereunder to any Indemnitee with respect to
Indemnified Liabilities to the extent such Indemnified Liabilities are found by
a final and nonappealable decision of a court of competent jurisdiction to have
resulted from the gross negligence or willful misconduct of such Indemnitee. No
Indemnified Person shall be liable to the Borrowers for any damages arising from
the use by others of information or materials obtained through electronic,
telecommunications or other information transmission systems provided that this
sentence will not, as to any Indemnified Person, apply to the extent such
Indemnified Person is found by a final, non-appealable judgment of a court to
have acted with willful misconduct or gross negligence. It is understood and
agreed that, to the extent not precluded by a conflict of interest (as
reasonably determined by the relevant Indemnitee), each Indemnitee shall
endeavor to work cooperatively with the Borrowers with a view towards minimizing
the legal and other expenses associated with any defense and any potential
settlement or judgment. To the extent reasonably practicable and not
disadvantageous to any Indemnitee (as reasonably determined by the relevant
Indemnitee), it is anticipated that a single counsel selected by the affected
Lenders may be used. Without limiting the foregoing, and to the extent permitted
by applicable law, the Borrowers agrees not to assert and to cause their
Subsidiaries not to assert, and hereby waives and agrees to cause their
Subsidiaries to so waive, all rights for contribution or any other rights of
recovery with respect to all claims, demands, penalties, fines, liabilities,
settlements, damages, costs and expenses of whatever kind or nature with respect
to the execution, delivery, enforcement, performance and

                                                                              62

administration of this Agreement, the other Loan Documents and any such other
documents, under or related to Environmental Laws, that any of them might have
by statute or otherwise against any Indemnitee, except to the extent such rights
result from the gross negligence or willful misconduct of such Indemnitee. All
amounts due under clauses (a), (b) and (c) of the first sentence of this Section
shall be payable not later than 30 days following written demand therefor.
Statements payable by the Borrowers pursuant to this Section shall be submitted
to Reid T. Campbell (Telephone No. (203) 458-2467) (Fax No. (203) 458-0754), at
the address of the Borrowers set forth in Section 10.2, or to such other Person
or address as may be hereafter designated by the Borrowers in a written notice
to the Administrative Agent. The agreements in this Section shall survive
repayment of the Loans and all other amounts payable hereunder.

          10.6 SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS. (a) This
Agreement shall be binding upon and inure to the benefit of the Borrowers, the
Lenders, the Administrative Agent, all future holders of the Loans and their
respective successors and assigns, except that the Borrowers may not assign or
transfer their rights or obligations under this Agreement without the prior
written consent of the Administrative Agent and each Lender. Neither of the
Guarantors may assign any of their obligations in respect of the Guarantees.

          (b) Any Lender may, without the consent of the Borrowers or the
Administrative Agent (but with notice to the Administrative Agent), in
accordance with applicable law, at any time sell to one or more banks, financial
institutions or other entities (each, a "PARTICIPANT") participating interests
in any Loan owing to such Lender, any Commitment of such Lender or any other
interest of such Lender hereunder and under the other Loan Documents. In the
event of any such sale by a Lender of a participating interest to a Participant,
such Lender's obligations under this Agreement to the other parties to this
Agreement shall remain unchanged, such Lender shall remain solely responsible
for the performance thereof, such Lender shall remain the holder of any such
Loan for all purposes under this Agreement and the other Loan Documents, and the
Borrowers and the Administrative Agent shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents. In no event shall
any Participant under any such participation have any right to approve any
amendment or waiver of any provision of any Loan Document, or any consent to any
departure by either Borrower therefrom, except to the extent that such
amendment, waiver or consent would, pursuant to Section 10.1, require the
consent of all Lenders. The Borrowers agree that if amounts owing by the
Borrowers under this Agreement and the Loans are due or unpaid, or shall have
been declared or shall have become due and payable upon the occurrence of an
Event of Default, each Participant shall, to the maximum extent permitted by
applicable law, be deemed to have the right of setoff in respect of its
participating interest in amounts owing under this Agreement to the same extent
as if the amount of its participating interest were owing directly to it as a
Lender under this Agreement, PROVIDED that, in purchasing such participating
interest, such Participant shall be deemed to have agreed to share with the
Lenders the proceeds thereof as provided in Section 10.7(a) as fully as if such
Participant were a Lender hereunder. The Borrowers also agrees that each
Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17
with respect to its participation in the Commitments and the Loans outstanding
from time to time as if such Participant were a Lender; PROVIDED that, in the
case of Section 2.16, such Participant shall have complied with the requirements
of said Section, and PROVIDED, FURTHER, that no Participant shall be entitled to
receive any greater amount pursuant to any such Section than the transferor
Lender would have been

<Page>

                                                                              63

entitled to receive in respect of the amount of the participation transferred by
such transferor Lender to such Participant had no such transfer occurred.

          (c) Any Lender (an "ASSIGNOR") may, in accordance with applicable law
and upon written notice to the Administrative Agent and the Borrowers, at any
time and from time to time assign to (A) any Lender, (B) an affiliate of any
Lender, PROVIDED THAT (i) such affiliate is a financial institution having a
senior unsecured debt rating of not less than "A-", or its equivalent, by S&P
and (ii) such Assignor has obtained the prior written consent of the
Administrative Agent to such assignment, such consent not be unreasonably
withheld or delayed or (C) an additional bank, financial institution or other
entity PROVIDED THAT, in the case of an assignment pursuant to this clause (C),
such Assignor has obtained the prior written consent of the Administrative Agent
and the Borrowers to such assignment, each such consent not be unreasonably
withheld or delayed (the entities described in (A), (B) and (C) each being
referred to as an "ASSIGNEE") all or any part of its rights and obligations
under this Agreement pursuant to an Assignment and Acceptance, substantially in
the form of EXHIBIT H, executed by such Assignee and such Assignor (and, where
the consent of the Borrowers or the Administrative Agent is required pursuant to
the foregoing provisions, by the Borrowers and/or the Administrative Agent) as
applicable; PROVIDED that (i) no such assignment of Revolving Credit Loans to an
Assignee (other than any Lender or any affiliate thereof) shall be in an
aggregate principal amount of less than $5,000,000 (other than in the case of an
assignment of all of a Lender's interests under this Agreement) and (ii) no such
assignment of Revolving Credit Commitments and/or Revolving Credit Loans (other
than in the case of an assignment of all of a Lender's interests under this
Agreement) shall result in such Lender's Commitments being reduced to less than
$5,000,000. Upon such execution, delivery, acceptance and recording, from and
after the effective date determined pursuant to such Assignment and Acceptance,
(w) the Assignee thereunder shall be a party hereto and, to the extent provided
in such Assignment and Acceptance, have the rights and obligations of a Lender
hereunder with Commitments or Loans as set forth therein, and (x) the Assignor
thereunder shall, to the extent provided in such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all of an Assignor's rights and obligations
under this Agreement, such Assignor shall cease to be a party hereto, except as
to Section 2.15, 2.16, 10.5 and 10.14 in respect of the period prior to such
effective date). Notwithstanding any provision of this Section (y) the consent
of the Borrowers shall not be required for any assignment that occurs at any
time when any Event of Default shall have occurred and be continuing and (z) the
parties to this Agreement acknowledge that the provisions of this Section
concerning assignments of Loans and Notes relate only to absolute assignments
and that such provisions do not prohibit assignments creating security interests
and further acknowledge that any Lender may at any time pledge or assign a
security interest in all or any portion of its interest and rights under this
Agreement (including all or any portion of its Notes) to secure obligations of
such Lender, including any pledge or assignment to secure obligations to any of
the twelve Federal Reserve Banks organized under Section 4 of the Federal
Reserve Act, 12 U.S.C. Section 341.

          (d) The Administrative Agent shall, on behalf of the Borrowers,
maintain at its address referred to in Section 10.2 a copy of each Assignment
and Acceptance delivered to it and a register (the "REGISTER") for the
recordation of the names and addresses of the Lenders and the Commitment of, and
principal amount of the Loans owing to, each Lender from time to time. The
entries in the Register shall be conclusive, in the absence of manifest error,
and the

<Page>

                                                                              64

Borrowers, the Administrative Agent and the Lenders shall treat each Person
whose name is recorded in the Register as the owner of the Loans and any Notes
evidencing such Loans recorded therein for all purposes of this Agreement. Any
assignment of any Loan, whether or not evidenced by a Note, shall be effective
only upon appropriate entries with respect thereto being made in the Register
(and each Note shall expressly so provide). Any assignment or transfer of all or
part of a Loan evidenced by a Note shall be registered on the Register only upon
surrender for registration of assignment or transfer of the Note evidencing such
Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or
more new Notes in the same aggregate principal amount shall be issued to the
designated Assignee, and the old Notes shall be returned by the Administrative
Agent to the Borrowers marked "canceled". The Register shall be available for
inspection by the Borrowers or any Lender (with respect to any entry relating to
such Lender's Loans) at any reasonable time and from time to time upon
reasonable prior notice.

          (e) Upon its receipt of an Assignment and Acceptance executed by an
Assignor and an Assignee (and, in any case where the consent of any other Person
is required by Section 10.6(c), by each such other Person) together with payment
to the Administrative Agent of a registration and processing fee of $3,500
(except that (x) no such registration and processing fee shall be payable in the
case of an Assignee which is an affiliate of the Assignor or a Person under
common management with the Assignor and (y) only one registration and processing
fee shall be payable in cases of contemporaneous multiple assignments by an
Assignor to Assignees which are affiliates of each other), the Administrative
Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the
effective date determined pursuant thereto record the information contained
therein in the Register and give notice of such acceptance and recordation to
the Administrative Agent and the Borrowers. On or prior to such effective date,
the Borrowers, at its own expense, upon request, shall execute and deliver to
the Administrative Agent (in exchange for the Revolving Credit Note of the
assigning Lender) a new Revolving Credit Note to such Assignee in an amount
equal to the Revolving Credit Commitment assumed or acquired by it pursuant to
such Assignment and Acceptance and, if the Assignor has retained a Revolving
Credit Commitment, a new Revolving Credit Note, as the case may be, to the
Assignor in an amount equal to the Revolving Credit Commitment. Such new Note or
Notes shall be dated the Closing Date and shall otherwise be in the form of the
Note or Notes replaced thereby.

          10.7 ADJUSTMENTS; SET-OFF. (a) Except to the extent that this
Agreement provides for a payment to be allocated to a particular Lender, if any
Lender (a "Benefitted Lender") shall at any time receive any payment of all or
part of the obligations under the Credit Agreement or the other Loan Documents,
owing to it, or receive any collateral in respect thereof (whether voluntarily
or involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in Section 8(f), or otherwise), in a greater proportion than any
such payment to or collateral received by any other Lender, if any, in respect
of such other Lender's obligations under the Credit Agreement or the other Loan
Documents, such Benefitted Lender shall purchase for cash from the other Lenders
a participating interest in such portion of each such other Lender's obligations
under the Credit Agreement or the other Loan Documents, or shall provide such
other Lenders with the benefits of any such collateral, as shall be necessary to
cause such Benefitted Lender to share the excess payment or benefits of such
collateral ratably with each of the Lenders; provided, however, that if all or
any portion of such excess payment or benefits is

<Page>

                                                                              65

thereafter recovered from such Benefitted Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest.

          (b) In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right, without prior notice to the Borrowers,
any such notice being expressly waived by the Borrowers to the extent permitted
by applicable law, upon any amount becoming due and payable by a Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise), to set
off and appropriate and apply against such amount any and all deposits (general
or special, time or demand, provisional or final), in any currency, and any
other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Lender or any branch or agency thereof to or for the
credit or the account of such Borrower. Each Lender agrees promptly to notify
the Borrowers, as the case may be, and the Administrative Agent after any such
setoff and application made by such Lender, PROVIDED that the failure to give
such notice shall not affect the validity of such setoff and application.

          10.8 COUNTERPARTS. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. Delivery of an executed signature page of this Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof. A set of the copies of this Agreement signed by all the
parties shall be lodged with the Borrowers and the Administrative Agent.

          10.9 SEVERABILITY. Any provision of this Agreement that is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          10.10 INTEGRATION. This Agreement and the other Loan Documents
represent the entire agreement of the Borrowers the Administrative Agent, the
Syndication Agent and the Lenders with respect to the subject matter hereof and
thereof, and there are no promises, undertakings, representations or warranties

the Administrative Agent and the Lenders, on one hand, and the Borrowers, on the

          10.15 RELEASE OF GUARANTEE OBLIGATIONS. Notwithstanding anything to

of calculation of financial covenants, standards or terms in this Agreement,
then the Borrowers and the Administrative Agent agree to enter into negotiations
in order to amend such provisions of this Agreement so as to equitably reflect
such Accounting Changes with the desired result that the criteria for evaluating

Changes as if such Accounting Changes had not been made. Until such time as such
an amendment shall have been executed and delivered by the Borrowers, the
Administrative Agent and the Majority Lenders, all financial covenants,
standards and terms in this Agreement shall continue to be calculated or
