                  For purposes of the foregoing, (i) if either S&P or Moody's
         shall not have in effect a rating for the Index Debt (other than by
         reason of the circumstances referred to in the last sentence of this
         definition), then the Borrowers and the Lenders shall negotiate in good
         faith to select a substitute rating agency and during such negotiations
         the ratings with respect to the Index Debt shall be deemed to be equal
         to the available remaining rating; (ii) if both S&P and Moody's shall
         not have in effect a rating for the Index Debt (other than by reason of
         the circumstances referred to in the last sentence of this definition),
         then such rating agencies shall be deemed to have established ratings
         in Category 3; (iii) if the ratings established or deemed to have been
         established by S&P and Moody's for the Index Debt shall fall within
         different Categories, the ratings with respect to the Index Debt shall
         be deemed to be (A) the higher of the two ratings so long as the two
         ratings are adjacent and (B) the rating that is one rating higher than
         the lower of the two ratings so long as the two ratings are not
         adjacent; and (iv) if the ratings established or deemed to have been
         established by S&P and Moody's for the Index Debt shall be changed
         (other than as a result of a change in the rating system of S&P or
         Moody's), such change shall be effective as of the date on which it is
         first announced by the applicable rating agency. Each change in the
         Applicable Rate shall apply during the period commencing on the
         effective date of such change and ending on the date immediately
         preceding the effective date of the next such change. If the rating
         system of S&P or Moody's shall change, or if either such rating agency
         shall cease to be in the business of rating corporate debt obligations,
         the Borrowers and the Lenders shall negotiate in good faith to amend
         this definition to reflect such changed rating system or the
         unavailability of ratings from such rating agency and, pending the
         effectiveness of any such amendment, the Applicable Rate shall be
         determined by reference to the rating of such rating agency most
         recently in effect prior to such change or cessation and the rating of
         the other rating agency.

                  "APPROPRIATE LENDER" means (a) as to the Facility, a Lender
         that has a Commitment for a portion of, or an Advance under, the

                  SECTION 2.01. THE ADVANCES. (a) REVOLVING CREDIT ADVANCES.
Each Lender severally agrees, on the terms and conditions hereinafter set forth,
to make one or more Revolving Credit Advances (such advances, together with (i)
the Swing Line Advances and (ii) to the extent any Lender elects to make them,
Auction Bid Advances as provided in subsection (c) of this Section 2.01, being
the "Advances") to the Borrowers from time to time on any Business Day during
the period from the date hereof to but excluding the Termination Date (or, if
earlier with respect to either Borrower, the date on which the obligations of
the Lenders to make Advances to such Borrower are terminated pursuant to Article
VI) in an aggregate principal amount not to exceed at any time outstanding the
amount set opposite such Lender's name on Schedule 2.01 hereof or, if such
Lender has entered into any Assignment and Acceptance, set forth for such Lender
in the Register maintained by the Administrative Agent pursuant to Section
8.07(d), as such amount may be reduced pursuant to Section 2.05 (such Lender's
"Commitment"); PROVIDED, HOWEVER, that (A) the Facility Usage shall not at any
time exceed the Facility at such time, (B) the deemed use of the aggregate
amount of the Commitments resulting from outstanding Auction Bid Advances and
Swing Line Advances shall be applied to all the Lenders ratably according to
their respective Commitments and (C) each Revolving Credit Advance shall be made
as part of a Borrowing consisting of Revolving Credit Advances made by the
Lenders ratably in accordance with their Commitments. Each Revolving Credit
Borrowing shall be in an aggregate amount not less than $25,000,000 and in an
integral multiple of $5,000,000. Within the limits of the foregoing and of each
Lender's Commitment, each Borrower may, from time to time prior to the earlier
of the Termination Date and the date on which the obligations of the Lenders to
make Advances to such Borrower are terminated pursuant to Article VI, borrow
under this Section 2.01(a), repay pursuant to Section 2.06, prepay pursuant to
Section 2.10 and reborrow under this Section 2.01(a).

                  (b) THE SWING LINE ADVANCES. (i) Each Swing Line Bank
severally agrees, on the terms and subject to the conditions hereinafter set
forth, to make one or more Base Rate Advances (such advances made pursuant to
this Section 2.01(b) being the "Swing Line Advances") to the Borrowers from time
to time on any Business Day during the period from the date hereof to but
excluding the Termination Date (or, if earlier with respect to either
Borrower, the date on which the obligations of the Lenders to make Advances
to such Borrower are terminated pursuant to Article VI) in an aggregate
amount at any time outstanding not in excess of the amount of such Swing Line
Bank's Swing Line Commitment at such time; PROVIDED, HOWEVER, that
immediately after giving effect to each such Swing Line Advance, the Facility
Usage shall not exceed the Facility; PROVIDED FURTHER, HOWEVER, that (A) each
Swing Line Advance shall be deemed to utilize the Commitment of each Lender
by such Lender's pro rata portion (based on the Commitments of the Lenders)
of the amount of such Swing Line Advance; (B) the aggregate amount of Swing
Line Advances of each Swing Line Bank at any time outstanding, when added to
the aggregate amount of Revolving Credit Advances of such Swing Line Bank
then outstanding, may not exceed the Commitment of such Swing Line Bank; (C)
each Swing Line Borrowing

                                                                              13

shall be in an amount of at least $25,000,000 and shall be in an integral
multiple of $5,000,000; and (D) each Swing Line Advance shall mature and be
repaid on the fifth Business Day after the date of such Swing Line Borrowing.
In no event may Swing Line Advances be borrowed hereunder if (x) the
Administrative Agent shall have received notice from the Majority Lenders
specifying that a Default or Event of Default shall have occurred and be
continuing, (y) such Default or Event of Default shall not have been
subsequently cured or waived and (z) any other applicable condition precedent
set forth in Article III has not been fulfilled or waived in accordance with
the terms thereof. All Swing Line Advances shall at all times be Base Rate
Advances and may not be converted to Advances of a different type. Swing Line
Advances shall be made by the Swing Line Banks pro rata in accordance with
the relative amounts of their Swing Line Commitments which, after giving
effect to the foregoing provisions of this Section 2.01(b)(i), are available
for the making of Swing Line Advances. Within the limits and subject to the
conditions of the foregoing, each Borrower may, prior to the earlier of the
Termination Date and the date on which the obligations of the Lenders to make
Advances to such Borrower are terminated pursuant to Article VI, borrow under
this Section 2.01(b), repay pursuant to Section 2.06(b) or prepay pursuant to
Section 2.10 and reborrow under this Section 2.01(b).

                  (ii) Notwithstanding the occurrence of any Default or Event of
Default or noncompliance with the conditions precedent set forth in Article III
or the minimum borrowing amounts specified in Section 2.01, if any Swing Line
Advances shall remain outstanding at 10:00 a.m., New York City time, on the
fourth Business Day following the borrowing date thereof and if by such time on
such fourth Business Day the Administrative Agent shall have received neither
(i) a notice of borrowing delivered by the applicable Borrower pursuant to
Section 2.02 requesting that Revolving Credit Advances be made pursuant to
Section 2.01(a) on the immediately succeeding Business Day in an amount at least
equal to the aggregate principal amount of such Swing Line Advances nor (ii) any
other notice satisfactory to the Administrative Agent indicating the applicable
Borrower's intent to repay all such Swing Line Advances on or before the
immediately succeeding Business Day with funds obtained from other sources, the
Administrative Agent shall be deemed to have received a notice from such
Borrower pursuant to Section 2.02 requesting that a Revolving Credit
Borrowing of Base Rate Advances be made pursuant to Section 2.01(a) on such
immediately succeeding Business Day in an amount equal to the aggregate
amount of such Swing Line Advances, and the procedures set forth in Section
2.02 shall be followed in making such Base Rate Advances, provided that the
proceeds of such Base Rate Advances received by the Administrative Agent
shall be immediately delivered to the Swing Line Banks and applied to the
direct repayment of such Swing Line Advances. Effective on the day such Base
Rate Advances are made, the portion of the Swing Line Advances so paid shall
no longer be outstanding as Swing Line Advances and shall be outstanding as
Revolving Credit Advances of the Lenders. On the day such Revolving Credit
Borrowing is made, each Swing Line Bank's proportionate share of such
Revolving Credit Advances shall be deemed to be funded from its Swing Line
Advances being refunded. Each Borrower authorizes the Administrative Agent
and each of the Swing Line Banks to charge such Borrower's accounts with the
Administrative Agent or such Swing Line Bank (up to the amount available in
each such account) in order to immediately pay the amount of such Swing Line
Advances to the extent amounts received from the Lenders are not sufficient
to repay in full such Swing Line Advances. If any portion of any such amount
paid (or deemed paid) to a Swing Line Bank should be recovered by or on
behalf of such Borrower from such Swing Line Bank in the event of the
bankruptcy or reorganization of such Borrower or otherwise, the loss of the
amount so recovered

shall be ratably shared among all the Lenders in the manner contemplated by
Section 2.15.

                  (iii) If, for any reason (including without limitation, the
occurrence of an event described in Section 6.01(e)), Base Rate Advances may not
be, or are not, made pursuant to subparagraph (b)(ii) of this Section to repay
Swing Line Advances as required by such subparagraph, effective on the date such
Base Rate Advances would otherwise have been made, each Lender severally,
unconditionally and irrevocably agrees that it shall, without regard to the
occurrence of any Default or Event of Default, purchase a participating interest
in such Swing Line Advances ("Unrefunded Swing Line Advances") in an amount
equal to the amount of Base Rate Advances which would otherwise have been made
by such Lender pursuant to subparagraph (b)(ii) of this Section. Each Lender
will immediately transfer to the Administrative Agent, in immediately available
funds, the amount of its participation, and the proceeds of such participation
shall be distributed by the Administrative Agent to the Swing Line Banks, pro
rata in accordance with the amount of their Swing Line Advances, to such extent
as will reduce the amount of the participating interest retained by each such
Swing Line Bank in its Swing Line Advances to the amount of the Base Rate
Advances which were to have been made by each such Swing Line Bank pursuant to
subparagraph (b)(ii) of this Section. Each Lender purchasing a participating
interest in Swing Line Advances under this Section 2.01(b)(iii) shall have the
same rights as a Lender under this Agreement. In the event any Lender fails to
make available to a Swing Line Bank the amount of such Lender's participation as
provided in this subparagraph (b)(iii), such Swing Line Bank shall be entitled
to recover such amount on demand from such Lender together with interest at
the customary rate set by the Swing Line Bank for correction of errors among
banks for one Business Day and thereafter at the Base Rate then in effect.

                  (iv) Each Lender's obligation to make Revolving Credit
Advances pursuant to subparagraph (b)(ii) of this Section and to purchase
participating interests pursuant to subparagraph (b)(iii) of this Section shall
be absolute and unconditional and shall not be affected by any circumstance,
including, without limitation, (i) any set-off, counterclaim, recoupment,
defense or other right which such Lender or either Borrower may have against a
Swing Line Bank, a Borrower, or any other Person, as the case may be, for any
reason whatsoever; (ii) the occurrence or continuance of a Default or an Event
of Default; (iii) any adverse change in the condition (financial or otherwise)
of either Borrower or any of its Subsidiaries; (iv) any breach of this Agreement
by either Borrower or any Lender; or (v) any other circumstance, happening or
event whatsoever, whether or not similar to any of the foregoing.

                  (c) THE AUCTION BID ADVANCES. (i) In order to request Auction
Bid Borrowings, a Borrower shall hand deliver or telecopy to the Administrative
Agent a duly completed Auction Bid Request substantially in the form of Exhibit
A-1 hereto, to be received by the Administrative Agent (i) in the case of a
Eurodollar Rate Borrowing, not later than 10:00 a.m., New York City time, four
Business Days before a proposed Auction Bid Borrowing and (ii) in the case of a
Fixed Rate Borrowing, not later than 10:00 a.m., New York City time, one
Business Day before a proposed Auction Bid Borrowing. No Base Rate Advance shall
be requested in, or made pursuant to, an Auction Bid Request. An Auction Bid
Request that does not conform substantially to the format of Exhibit A-1 may be
rejected in the Administrative Agent's sole discretion, and the Administrative
Agent shall promptly notify the applicable Borrower of such rejection by
telecopier. Such request shall in each case refer to this Agreement and specify
(x) whether the Borrowing then being requested is to be a Eurodollar Borrowing
or a Fixed Rate Borrowing, (y) the date of such

<Page>

                                                                              15

Borrowing (which shall be a Business Day occurring on or prior to the
Termination Date) and the aggregate principal amount thereof which shall be
in a minimum principal amount of $25,000,000 and in an integral multiple of
$5,000,000, and (z) the Interest Period with respect thereto. Promptly after

Administrative Agent shall invite by telecopier (in the form set forth in
Exhibit A-2 hereto) the Lenders to bid, on the terms and conditions of this
Agreement, to make Auction Bid Advances pursuant to the Auction Bid Request.
A Borrower may request Auction Bids for up to three separate Interest Periods
in a single Auction Bid Request, provided that the aggregate principal amount
of each Borrowing requested shall be in a minimum principal amount of
$25,000,000 and in an integral multiple of $5,000,000.

                  (ii) Each Lender may, in its sole discretion, make one or more
Auction Bids to the applicable Borrower responsive to an Auction Bid Request.

City time, three Business Days before a proposed Auction Bid Borrowing and
(B) in the case of a Fixed Rate Borrowing, not later than 9:30 a.m., New York
City time, on the day of a proposed Auction Bid Borrowing. Multiple bids with
respect to each Interest Period specified in the related Auction Bid Request
will be accepted by the Administrative Agent. Auction Bids that do not
conform substantially to the format of Exhibit A-3 may be rejected by the
Administrative Agent after conferring with, and upon the instruction of, the
applicable Borrower, and the Administrative Agent shall notify the Lender
making such nonconforming bid of such rejection as soon as practicable. Each
Auction Bid shall refer to this Agreement and specify (x) the principal
amount (which shall be in a minimum amount of $5,000,000 and in an integral
multiple of $1,000,000, and which may equal the entire principal amount of
the Auction Bid Borrowing requested by the applicable Borrower) of the
Auction Bid Advance or Advances with respect to an Interest Period that the
applicable Lender is willing to make to the applicable Borrower, (y) the
Auction Bid Rate or Rates at which such Lender is prepared to make the
Auction Bid Advance or Advances and (z) the Interest Period and the last day
thereof. If a Lender submits an Auction Bid containing offers to make Auction
Bid Advances for different Interest Periods, then such Lender may specify the
maximum aggregate principal amount of Auction Bid Advances (which shall not
be less than $5,000,000 and which shall be an integral multiple of
$1,000,000) that such Lender is willing to make in response to the related
Auction Bid Request, and the applicable Borrower may not accept offers from
such Lender for Auction Bid Advances in an aggregate principal amount that
exceeds such specified maximum aggregate principal amount. An Auction Bid
submitted by a Lender pursuant to this subparagraph (ii) shall be irrevocable
unless rejected by the applicable Borrower.

                  (iii) The Administrative Agent shall, by 10:00 a.m., New York
City time, on the day specified in subparagraph (ii) above by which Auction Bids
must be received, notify the applicable Borrower by telecopier of all the
Auction Bids made, the Auction Bid Rate and the principal amount of each Auction
Bid Advance in respect of which an Auction Bid was made and the identity of the
Lender that made each bid. The Administrative Agent shall send a copy of all
Auction Bids to the applicable Borrower for its records as soon as practicable
after completion of the bidding process set forth in this Section 2.01(c).

                  (iv) The applicable Borrower may in its sole and absolute
discretion, subject only to the provisions of this subparagraph (iv) and Section
2.01, accept or reject any Auction Bid referred to in subparagraph (iii) above;
PROVIDED, HOWEVER,

<Page>

                                                                              16

that, immediately after giving effect to any such acceptance, the Facility
Usage shall not exceed the Facility. The applicable Borrower shall notify the
Administrative Agent by telephone, confirmed by telecopier in the form of an
Auction Bid Accept Letter substantially in the form of Exhibit A-4, whether
and to what extent it has decided to accept any of or all the bids referred
to in subparagraph (iii) above, (A) in the case of a Eurodollar Auction Bid
Advance, not later than 10:30 a.m. New York City time, three Business Days
before a proposed Auction Bid Borrowing, and (B) in the case of a Fixed Rate
Borrowing, not later than 10:30 a.m., New York City time, on the day of a
proposed Auction Bid Borrowing; PROVIDED, HOWEVER, that (A) the failure by
the applicable Borrower to give such notice shall be deemed to be a rejection
of all the bids referred to in subparagraph (iii) above, (B) any bid referred
to in subparagraph (iii) above which is not specified in such notice as being
accepted by the applicable Borrower shall (subject to clause (C) below) be
deemed rejected, (C) subject to the next following sentence, the applicable
Borrower shall not accept a bid for a particular Interest Period made at a
particular Auction Bid Rate if such Borrower has decided to reject a bid for
such Interest Period made at a lower Auction Bid Rate, (D) if the applicable
Borrower shall accept a bid or bids for a particular Interest Period made at
a particular Auction Bid Rate but the amount of such bid or bids plus the
amount of bids accepted at lower Auction Bid Rates exceeds the aggregate
principal amount specified for such Interest Period in the Auction Bid
Request, then such Borrower shall be deemed to have accepted a portion of
such bid or bids in an amount equal to the aggregate principal amount
specified for such Interest Period in the Auction Bid Request less the amount
of all other Auction Bids at a lower Auction Bid Rate accepted with respect
to such Interest Period, which acceptance, in the case of multiple bids at
such Auction Bid Rate, shall be made pro rata in accordance with the amount
of each such bid at such Auction Bid Rate, (E) Auction Bids shall not be
accepted for Auction Bid Advances in an amount in excess of the amount
specified in the relevant Auction Bid Request, and (F) except pursuant to
clause (D) above, no bid shall be accepted for an Auction Bid Advance unless
such Auction Bid Advance is in a minimum principal amount of $5,000,000 and
an integral multiple of $1,000,000; PROVIDED FURTHER, HOWEVER, that if an
Auction Bid Advance must be in an amount less than $5,000,000 because of the
provisions of clause (D) above, such Auction Bid Advance may be for a minimum
of $1,000,000 or any integral multiple thereof, and in calculating the pro
rata allocation of acceptances of portions of multiple bids at a particular
Auction Bid Rate pursuant to clause (D), the amounts shall be rounded to
integral multiples of $1,000,000 in a manner which shall be in the discretion
of the applicable Borrower. If a Lender submits an Auction Bid for multiple
Interest Periods specifying a maximum aggregate principal amount of Auction
Bid Advances that such Lender is willing to make in respect of an Auction Bid
Request and the applicable Borrower accepts Auction Bids from such Lender for
more than one Interest Period, then such Borrower shall instruct the
Administrative Agent how to apportion such Borrower's acceptances among such
bids for different Interest Periods to the extent, if any, necessary to
provide for acceptance of bids for such maximum specified amount of Auction
Bid Advances, but no more than such maximum amount. A notice given by the
applicable Borrower pursuant to this subparagraph (iv) shall be irrevocable.

                  (v) The Administrative Agent shall, by telecopy, promptly
notify each bidding Lender whether or not its Auction Bid has been accepted (and
if so, for which Interest Period or Interest Periods and in what amount and at
what Auction Bid Rate for each such Interest Period), and each successful bidder
will thereupon become bound, subject to the other applicable conditions
hereof, to make the Auction Bid Advance in respect of which its bid has been
accepted.

                  (vi) An Auction Bid Request shall not be made within five

                  (viii) All Notices required by this Section 2.01(c) shall be

this Agreement, neither Borrower shall request, and no Lender shall make, any
Auction Bid Advance having a borrowing date after the seventh day prior to the

Chase to determine the applicable Eurodollar Rate, which Chase shall promptly
provide. Promptly after receipt of such Eurodollar Rate from Chase, the
Administrative Agent shall notify the applicable Borrower and each Appropriate
Lender of the applicable interest rate under Section 2.07. No Auction Bid
Advance and no Fixed Rate Advance shall be requested or made pursuant to a
Notice of Borrowing. The Administrative Agent shall promptly advise the Lenders
of any notice given pursuant to this 2.02(a) and of each Lender's portion of the
requested Borrowing.

                  (b) Each Swing Line Borrowing shall be made on notice, given
not later than 12:00 noon (New York City time) on the date of the proposed Swing
Line Borrowing, by the applicable Borrower to the Administrative Agent, which
shall give each Swing Line Bank prompt notice thereof and of its portion of the
requested Swing Line Borrowing. Each such notice of a Swing Line Borrowing (the
"Notice of Swing Line Borrowing") shall be in the form of Exhibit B-2 or in such
other form as the Administrative Agent and the applicable Borrower may agree
upon, and shall be given by telephone, telex or telecopier and, if by
telephone, shall be confirmed immediately in writing (which may be by
telecopier) and shall specify therein the requested date (which shall be a
Business Day) and amount of such Swing Line Borrowing. Each Swing Line Bank
shall, not later than 3:00 p.m., New York City time, on the requested
borrowing date, make its portion of the requested Swing Line Borrowing
available to the Administrative Agent by wire transfer of immediately
available funds to the Administrative Agent. After the Administrative Agent's
receipt of such funds and upon fulfillment of the conditions set forth in
Article III, the Administrative Agent will make such funds available to the
applicable Borrower at the Administrative Agent's aforesaid address, or, if a
Borrowing shall not occur on

                                                                              18

such date because any condition precedent herein specified shall not have
been met, return the amounts so received to the respective Swing Line Banks.

                  (c) Each Notice of Borrowing and Notice of Swing Line
Borrowing shall be irrevocable and binding on the applicable Borrower.

                  SECTION 2.03. GENERAL PROVISIONS RELATING TO ADVANCES. (a) If
(i) the Administrative Agent shall, at least one Business Day before the date of
any requested Borrowing comprised of Eurodollar Rate Advances, determine that
dollar deposits in the principal amounts of the Eurodollar Rate Advances
comprising such Borrowing are not generally available in the London interbank
market or that reasonable means do not exist for determining the Eurodollar Rate
or (ii) if the Majority Lenders shall, at least one Business Day before the date
of any requested Borrowing comprised of Eurodollar Rate Advances, notify the
Administrative Agent that the Eurodollar Rate for Eurodollar Rate Advances
comprising such Borrowing will not adequately reflect the cost to such Majority
Lenders of making or funding their respective Eurodollar Rate Advances for such
Borrowing, then, in each case, the Administrative Agent shall give prompt notice
thereof to the Borrowers and the right of the Borrowers to select Eurodollar
Rate Advances for such Borrowing or any subsequent Borrowing shall be suspended
until the Administrative Agent shall notify the Borrowers and the Lenders that
the circumstances giving rise to such suspension no longer exist, and each
Advance comprising any such Borrowing shall be a Base Rate Advance.

                  (b) In the case of any Borrowing to be comprised of Eurodollar
Rate Advances or Fixed Rate Advances, the applicable Borrower shall indemnify
each Lender against any loss, cost or expense incurred by such Lender as a
result of any failure to fulfill on or before the proposed date of Borrowing for
such Borrowing the applicable conditions set forth in Article III, including,
without limitation, any loss (including loss of anticipated profits), cost or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Lender to fund the Advance to be made by such
Lender as part of such Borrowing when such Advance, as a result of such failure,
is not made on such date. Each Lender agrees to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions)
to minimize the amount of any loss of anticipated profits payable by the
applicable Borrower to such Lender pursuant to the immediately preceding
sentence.

                  (c) Subject to Section 2.18 and, in the case of Swing Line
Advances, Sections 2.01(b) and 2.02(b), each Lender shall make each Advance to
be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Administrative Agent in New York, New York,
not later than 11:00 a.m., New York City time (or 2:00 p.m., New York City time,
in the case of a Base Rate Advance), and the Administrative Agent shall promptly
credit the amounts so received to the general deposit account of the applicable
Borrower with the Administrative Agent or, if a Borrowing shall not occur on
such date because any condition precedent herein specified shall not have been
met, return the amounts so received to the respective Lenders. Auction Bid Rate
Advances shall be made by the Lender or Lenders whose Auction Bids therefor are
accepted pursuant to Section 2.01(c) in the amounts so accepted and Revolving
Credit Advances shall be made by the Lenders pro rata in accordance with Section
2.01(a).

                  (d) Unless the Administrative Agent shall have received notice
from a Lender prior to the date of any Revolving Credit Borrowing that such
Lender will not make available to the Administrative Agent such Lender's ratable
portion of such

<Page>

                                                                              19

Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such Borrowing
in accordance with subsection (a) of Section 2.02 and the Administrative
Agent may, in reliance upon such assumption, make available to the applicable
Borrower on such date a corresponding amount. If and to the extent that such
Lender shall not have so made such ratable portion available to the
Administrative Agent, such Lender and the applicable Borrower severally agree
to repay to the Administrative Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount
is made available to such Borrower until the date such amount is repaid to
the Administrative Agent, at (i) in the case of such Borrower, the interest
rate applicable at the time to Advances comprising such Borrowing and (ii) in
the case of such Lender, the Federal Funds Rate. If such Lender shall repay
to the Administrative Agent such corresponding amount, such amount so repaid
shall constitute such Lender's Advance as part of such Borrowing for purposes
of this Agreement.

                  (e) The failure of any Lender to make the Advance to be made
by it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Advance on the date of such Borrowing,
but no Lender shall be responsible for the failure of any other Lender to make
the Advance to be made by such other Lender on the date of any Borrowing.

                  SECTION 2.04. FEES. (a) The Borrowers agree, jointly and
severally, to pay to the Administrative Agent for the account of each Lender a
facility fee, which shall accrue at the Applicable Rate on the daily amount of
such Lender's Commitment from time to time in effect (whether used or unused)
from and including the date hereof in the case of each Bank and from the
effective date specified in the Assignment and Acceptance pursuant to which
it became a Lender in the case of each other Lender, to but excluding the
date on which such Commitment terminates. Accrued facility fees shall be
payable in arrears on the last Business Day of March, June, September and
December of each year, commencing June 30, 2001, on any date on which the
obligations of the Lenders to make Advances to a Borrower are terminated
pursuant to Article VI and on the Termination Date.

                  (b) The Borrowers agree, jointly and severally, to pay to the
Administrative Agent for its own account such fees as may from time to time be
agreed between the Administrative Agent and the Borrowers.

                  (c) For each day prior to and including the Termination Date
on which the aggregate amount of Facility Usage exceeds 50% of the aggregate
amount of the Commitments, each Borrower agrees to pay to the Administrative
Agent for the account of each Lender a utilization fee on the unpaid principal
amount of each Advance owed by it to such Lender at a rate per annum equal to
the Applicable Rate in effect for such day. Accrued utilization fees shall be
payable in arrears on the last Business Day of March, June, September and
December of each year, commencing June 30, 2001, on any date on which the
Advances become due and payable pursuant to Article VI and on the Termination
Date.

                  SECTION 2.05. TERMINATION OR REDUCTION OF THE FACILITY. (a)
The Commitments and the Swing Line Commitments shall be automatically terminated
on the Termination Date.

                  (b) The Borrowers shall have the right at any time prior to
the Termination Date, upon at least three Business Days' notice to the
Administrative

<Page>

                                                                              20

Agent, to terminate in whole or reduce ratably in part the unused portion of
the Facility (such unused portion being determined by subtracting the
Facility Usage from the Facility); PROVIDED, HOWEVER, that each partial
reduction shall be in an amount not less than $25,000,000 or an integral
multiple of $5,000,000 in excess thereof; PROVIDED FURTHER, HOWEVER, that the
Commitments shall not in any event be reduced to an amount less than the
Swing Line Commitments. Each notice delivered by the Borrowers pursuant to
this Section 2.05(b) shall be irrevocable; PROVIDED that a notice of
termination of the Commitments delivered by the Borrowers may state that such
notice is conditioned upon the effectiveness of other credit facilities, in
which case such notice may be revoked by the Borrowers (by notice to the
Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied.

                  (c) Each reduction in the aggregate Commitments hereunder
shall be made ratably among the Lenders in accordance with their respective
Commitments. The Borrowers agree, jointly and severally, to pay to the
Administrative Agent for the account of the Lenders, on the date of each
termination or reduction, the facility fees on the amount of the Commitments so
terminated or reduced accrued to the date of such termination or reduction. Each
reduction in the aggregate Swing Line Commitments hereunder shall be made
ratably among the Swing Line Banks in accordance with their respective Swing
Line Commitments.

                  (d) Upon at least three Business Days' irrevocable notice to
the Administrative Agent, the Borrowers may at any time prior to the Termination
Date in whole permanently terminate, or from time to time in part permanently
reduce, the Swing Line Commitments; PROVIDED, HOWEVER, that (i) any outstanding
Swing Line Advances that would exceed the reduced or terminated Swing Line
Commitments must be prepaid in accordance with Section 2.10(b) and (ii) each
partial reduction of the Swing Line Commitments shall be in an integral multiple
of $5,000,000.

                  (e) Upon at least three Business Days' irrevocable notice to
the Administrative Agent, each Borrower may at any time prior to the Termination
Date in whole permanently terminate such Borrower's rights to borrow under this
Agreement; PROVIDED, HOWEVER, that any outstanding Advances made to such
Borrower, all accrued and unpaid interest thereon and all other amounts owed by
such Borrower hereunder (including indemnities with respect to any payments in
connection with such termination) shall be paid in full on or before the
effective date of any such termination in accordance with the terms hereof.

                  SECTION 2.06. REPAYMENT OF ADVANCES. (a) REVOLVING CREDIT
ADVANCES. The principal amount of each Revolving Credit Advance made to either
Borrower shall become due and payable, and such Borrower agrees to pay the
outstanding principal balance of each such Advance, on the Maturity Date.

                  (b) SWING LINE ADVANCES. Each Borrower shall repay the
outstanding principal amount of any Swing Line Advance made to it on the earlier
of (i) the date that is five Business Days after the date on which such Swing
Line Advance was made and (ii) the Termination Date.

                  (c) AUCTION BID ADVANCES. Each Borrower shall repay the
aggregate principal amount of each Auction Bid Advance made to it on the earlier
of (i) the last day of the Interest Period applicable to such Auction Bid
Advance and (ii) the Termination Date.

<Page>

                                                                              21


                  (d) Each Lender and each Swing Line Bank shall, and is hereby
authorized by each Borrower to, maintain in accordance with its usual practice
records evidencing the indebtedness of such Borrower to such Lender hereunder
from time to time, including the amounts and Types of and Interest Periods
applicable to the Advances made by such Lender from time to time and the amounts
of principal and interest paid to such Lender from time to time in respect of
such Advances.

                  (e) The entries made in the records maintained pursuant to
paragraph (d) of this Section 2.06 and in the Register maintained by the
Administrative Agent pursuant to Section 8.07(d) shall be PRIMA FACIE evidence
of the existence and amounts of the obligations of each Borrower to which such
entries relate; PROVIDED, HOWEVER, that the failure of any Lender, any Swing
Line Bank or the Administrative Agent to maintain or to make any entry in
such records or the Register, as applicable, or any error therein, shall not
in any manner affect the obligations of such Borrower to repay the Advances
in accordance with the terms of this Agreement.

                  SECTION 2.07. INTEREST. (a) ORDINARY INTEREST. Each Borrower
shall pay interest on the unpaid principal amount of each Advance owed by it to
each Lender from the date of such Advance until such principal amount shall
become due and payable, at the following rates per annum:

                  (i) BASE RATE ADVANCES. If such Advance is a Base Rate Advance
         (including a Swing Line Advance), a rate per annum for any day during
         the applicable Interest Period equal to the Base Rate in effect from
         time to time during such Interest Period, payable in arrears on the
         last day of such Interest Period and, if such Interest Period has a
         duration of six months, on the day which occurs during such Interest
         Period three months from the first day of such Interest Period.

                  (ii) EURODOLLAR RATE ADVANCES. If such Advance is a Eurodollar
         Rate Advance, a rate per annum for any day during the applicable
         Interest Period equal to the sum of (A) the Eurodollar Rate determined
         by Chase to be in effect for the Interest Period applicable to such
         Eurodollar Rate Advance plus (B) in the case of each Eurodollar
         Revolving Credit Advance, the Applicable Rate in effect from time to
         time during such Interest Period, and, in the case of each Eurodollar
         Auction Bid Advance, the Margin (which may be negative) applicable to
         such Advance, in each case payable in arrears on the last day of such
         Interest Period and, if such Interest Period has a duration of six
         months, on the day which occurs during such Interest Period three
         months from the first day of such Interest Period.

                  (iii) FIXED RATE ADVANCES. If such Advance is a Fixed Rate
         Advance, a rate per annum equal to the Fixed Rate applicable to such
         Advance, payable in arrears on the last day of the Interest Period
         applicable to such Fixed Rate Advance and, if such Interest Period has
         a duration of more than 90 days, on each day which occurs during such
         Interest Period every 90 days from the first day of such Interest
         Period.

                  (b) DEFAULT INTEREST. Each Borrower shall pay interest on the
unpaid principal amount of each Advance made to it that is not paid when due
and, to the extent permitted by law, on the unpaid amount of all interest, fees
and other amounts payable hereunder by it that is not paid when due, payable on
demand, at a rate per annum equal at all times to (i) in the case of any amount
of principal, the greater of

<Page>

                                                                              22


(A) 2% per annum above the rate per annum required to be paid on such Advance
immediately prior to the date on which such amount became due and (B) 2% per
annum above the Base Rate in effect from time to time and (ii) in the case of
all other amounts, 2% per annum above the Base Rate in effect from time to time.

                  SECTION 2.08. ADDITIONAL INTEREST ON EURODOLLAR RATE ADVANCES.
The applicable Borrower shall pay to each Lender, so long as such Lender shall
be required under regulations of the Board of Governors of the Federal Reserve
System to maintain reserves with respect to liabilities or assets consisting of
or including Eurocurrency Liabilities, additional interest on the unpaid
principal amount of each Eurodollar Rate Advance of such Lender, from the date
of such Advance until such principal amount is paid in full, at an interest rate
per annum equal at all times to the remainder obtained by subtracting (i) the
Eurodollar Rate for the Interest Period for such Advance from (ii) the rate
obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus
the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period,
payable on each date on which interest is payable on such Advance. Such
additional interest shall be determined by such Lender and notified to the
applicable Borrower through the Administrative Agent.

                  SECTION 2.09. INTEREST RATE DETERMINATION. The Administrative
Agent shall give prompt notice to the applicable Borrower and the Appropriate
Lenders of the applicable Eurodollar Rate determined by Chase hereunder in
respect of each Interest Period for Eurodollar Rate Advances. The failure of the
Administrative Agent to give notice to the applicable Borrower pursuant to this
Section 2.09 shall not relieve such Borrower from its obligation to pay any
interest in accordance with the terms of this Agreement.

                  SECTION 2.10. PREPAYMENTS. (a) The Borrowers shall have no
right to prepay (i) any principal amount of any Revolving Credit Advances other
than as provided in subsection (b) below or (ii) any Auction Bid Advances.

                  (b) Each Borrower may, upon irrevocable notice given to the
Administrative Agent not later than 10:00 a.m. (New York City time) on the third
Business Day prior to the date of the proposed prepayment in the case of a
Eurodollar Rate Advance, and on the first Business Day prior to the date of the
proposed prepayment in the case of Base Rate Advances and Swing Line Advances,
stating the proposed date and aggregate principal amount of the prepayment, and
if such notice is given such Borrower shall, prepay the outstanding principal
amounts of the Advances made to it comprising part of the same Borrowing in
whole or ratably in part, together with accrued interest to the date of such
prepayment on the principal amount prepaid; PROVIDED, HOWEVER, that (x) each
partial prepayment shall be in an aggregate principal amount not less than
$25,000,000 or an integral multiple of $5,000,000 in excess thereof and (y) in
the case of any such prepayment of a Eurodollar Rate Advance, such Borrower
shall be obligated to reimburse the Lenders in respect thereof pursuant to
Section 8.04(c). Any prepayment of Advances after the Termination Date shall be
permanent, and no portion of Advances prepaid after the Termination Date may be
re-borrowed hereunder.

                  SECTION 2.11. INCREASED COSTS. (a) If, due to either (i) the
introduction of or any change (other than any change by way of imposition or
increase of reserve requirements, in the case of Eurodollar Rate Advances,
included in the Eurodollar Rate Reserve Percentage) in or in the interpretation
of any law or regulation or (ii) the compliance with any guideline or request
from any central bank or other governmental authority (whether or not having the
force of law), there shall

<Page>

                                                                              23

be any increase in the cost to any Lender of agreeing to make or making,
funding or maintaining Eurodollar Rate Advances or Fixed Rate Advances, then
the applicable Borrower, in the case of outstanding Advances, and each
Borrower, jointly and severally, in all other cases, agrees from time to
time, upon demand by such Lender (with a copy of such demand to the
Administrative Agent), to pay to the Administrative Agent for the account of
such Lender additional amounts sufficient to compensate such Lender for such
increased cost; PROVIDED, HOWEVER, that, before making any such demand, each
Lender agrees to use reasonable efforts (consistent with its internal policy
and legal and regulatory restrictions) to designate a different Applicable
Lending Office if the making of such a designation would avoid the need for,
or reduce the amount of, such increased cost and would not, in the reasonable
judgment of such Lender, be otherwise disadvantageous to such Lender. A
certificate as to the amount of such increased cost, submitted to the
applicable Borrower or the Borrowers, as the case may be, and the
Administrative Agent by such Lender, shall be conclusive and binding for all
purposes, absent manifest error.

                  (b) If any Lender determines that the adoption after the date
hereof of any applicable law, rule, regulation or guideline regarding minimum
capital, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof (whether or not
having the force of law) or compliance by any Lender with any such adoption or
change has the effect of reducing the rate of return on capital for such Lender
or any corporation controlling such Lender as a consequence of its Commitment or
Swing Line Commitment to lend hereunder to a level below that which such Lender
or such corporation could have achieved but for such adoption, change or
compliance, then from time to time, upon demand by such Lender, the Borrowers
agree, jointly and severally, to pay to such Lender such additional amount or
amounts as will compensate such Lender for such reduction.

                  SECTION 2.12. ILLEGALITY. Notwithstanding any other provision
of this Agreement, if any Lender shall in good faith determine that the
introduction of or any change in or in the interpretation of any law or
regulation makes it unlawful, or any central bank or other governmental
authority asserts that it is unlawful, for such Lender or its Eurodollar Lending
Office to perform its obligations hereunder to make Eurodollar Rate Advances or
to fund or maintain Eurodollar Rate Advances hereunder, such Lender shall so
notify the Borrowers and the Administrative Agent. Before giving any such notice
to the Borrowers pursuant to this Section, such Lender shall use reasonable
efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different lending office if such designation will
avoid the need for giving such notice and would not, in the judgment of such
Lender, be otherwise disadvantageous to such Lender. Upon receipt of such
notice, (i) each then outstanding Eurodollar Rate Advance of such Lender shall
automatically convert to a Base Rate Advance and shall be maintained as a Base
Rate Advance through the last day of the Interest Period applicable thereto,
(ii) such Lender shall not submit an Auction Bid in response to a request for
Eurodollar Auction Bid Advances, and (iii) the obligation of such Lender to make
Eurodollar Rate Advances shall be suspended until such Lender shall notify the
Borrowers and the Administrative Agent that the circumstances causing such
suspension no longer exist. Without limiting the Borrowers' rights under Section
2.16, if at any time after such Lender gives notice of a determination as
provided above in this Section 2.12, a Borrower notifies the Administrative
Agent that it wishes to make a Borrowing consisting of Eurodollar Rate Advances
(or if at the time of such notice, a Borrower has previously notified the
Administrative Agent of such a Borrowing, but such Borrowing has not yet been

<Page>

                                                                              24

made), such notification of Borrowing shall be deemed to request that such
Lender (and only such Lender) make an Advance in the form of a Base Rate
Advance for the Interest Period corresponding to the Interest Period
applicable to the Eurodollar Rate Advances to be made by the other Lenders.

                  SECTION 2.13. PAYMENTS AND COMPUTATIONS. (a) Each Borrower
shall make each payment hereunder not later than 11:00 a.m. (New York City time)
on the day when due in U.S. dollars to the Administrative Agent at its address
referred to in Section 8.02 in same day funds. Except as required under Section
2.12, each Revolving Credit Borrowing, each payment or prepayment of principal
of any Revolving Credit Borrowing, each payment of the facility fees, each
reduction of the Commitments and each conversion or continuation of any
Revolving Credit Borrowing with a Revolving Credit Borrowing of any Type, shall
be allocated pro rata among the Lenders in accordance with their respective
Commitments (or, if such Commitments shall have expired or been terminated, in
accordance with the respective principal amounts of their outstanding Revolving
Credit Advances). Each payment of principal of any Auction Bid Borrowing shall
be allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective principal amounts of their outstanding Auction
Bid Advances comprising such Borrowing. Each payment of interest on any Auction
Bid Borrowing shall be allocated pro rata among the Lenders participating in
such Borrowing in accordance with the respective amounts of accrued and unpaid
interest on their outstanding Auction Bid Advances comprising such Borrowing.
For purposes of determining the available Commitments of the Lenders at any
time, each outstanding Auction Bid Borrowing and each outstanding Swing Line
Borrowing shall be deemed to have utilized the Commitments of the Lenders
(including those Lenders which shall not have made Swing Line Advances or shall
not have made Advances as part of such Auction Bid Borrowing) pro rata in
accordance with such respective Commitments; provided, HOWEVER, that the
Commitments so deemed to be utilized shall in any event be available for the
purpose of refinancing such Borrowing or such Swing Line Borrowing, as the case
may be. Each Lender agrees that in computing such Lender's portion of any
Borrowing to be made hereunder, the Administrative Agent may, in its
discretion, round each Lender's percentage of such Borrowing to the next higher
or lower whole dollar amount. Upon its acceptance of an Assignment and
Acceptance and recording of the information contained therein in the Register
pursuant to Section 8.07(d), from and after the effective date specified in such
Assignment and Acceptance, the Administrative Agent shall make all payments
hereunder in respect of the interest assigned thereby to the Lender assignee
thereunder, and the parties to such Assignment and Acceptance shall make all
appropriate adjustments in such payments for periods prior to such effective
date directly between themselves.

                  (b) All computations of interest pursuant to Section 2.07 and
of fees payable hereunder shall be made by the Administrative Agent, and all
computations of interest pursuant to Section 2.08, shall be made by a Lender, on
the basis of a year of 360 days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such interest or fees are payable; PROVIDED, HOWEVER, that all
computations of interest based on the Base Rate when the Base Rate is determined
by reference to paragraph (a) of the definition thereof shall be made by the
Administrative Agent on the basis of a year of 365 or 366 days, as applicable,
in each case for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest is
payable. Each determination by the Administrative Agent (or, in the case of
Section 2.08, by a Lender) of an interest rate hereunder shall be conclusive and
binding for all purposes, absent manifest error.

                                                                              25

                  (c) Whenever any payment hereunder shall be stated to be due
on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may be;
PROVIDED, HOWEVER, that, if such extension would cause payment of interest on or
principal of Eurodollar Rate Advances to be made in the next following calendar
month, such payment shall be made on the next preceding Business Day.

                  (d) Unless the Administrative Agent shall have received notice
from a Borrower prior to the date on which any payment is due to the Lenders
hereunder that such Borrower will not make such payment in full, the
Administrative Agent may assume that such Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Lender on such
due date an amount equal to the amount then due such Lender. If and to the
extent that a Borrower shall not have so made such payment in full to the
Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to the Administrative
Agent, at the Federal Funds Rate.

                  SECTION 2.14. TAXES. (a) Any and all payments by a Borrower
hereunder shall be made, in accordance with Section 2.13, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect
thereto, EXCLUDING, in the case of each Lender and the Administrative Agent,
taxes imposed on or measured by its net income, and franchise taxes imposed
on it, by the jurisdiction under the laws of which such Lender or the
Administrative Agent (as the case may be) is organized or any political
subdivision thereof and, in the case of each Lender, taxes imposed on or
measured by its net income, and franchise taxes imposed on it, by the
jurisdiction of such Lender's Applicable Lending Office or any political
subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred
to as "Taxes"). If a Borrower shall be required by law to deduct any Taxes
from or in respect of any sum payable hereunder to any Lender or the
Administrative Agent, (i) the sum payable shall be increased as may be
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.14) such Lender or
the Administrative Agent (as the case may be) receives an amount equal to the
sum it would have received had no such deductions been made, (ii) such
Borrower shall make such deductions and (iii) such Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

                  (b) In addition, the Borrowers agree, jointly and severally,
to pay any present or future stamp or documentary taxes or any other excise or
property taxes, charges or similar levies which arise from any payment made
hereunder or from the execution, delivery, enforcement or registration of, or
otherwise with respect to, this Agreement (hereinafter referred to as "Other
Taxes").

                  (c) Without duplication with respect to any amounts paid
pursuant to Section 2.14(a) or (b), to the extent attributable to an Advance
made to a Borrower, such Borrower will, and in each other case, the Borrowers
will, on a joint and several basis, indemnify each Lender, each Swing Line Bank
and the Administrative Agent for the full amount of Taxes or Other Taxes
(including, without limitation, any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this

<Page>

                                                                              26

Section 2.14) paid by such Lender, such Swing Line Bank or the Administrative
Agent (as the case may be) and any liability (including penalties, interest
and expenses) arising therefrom or with respect thereto, whether or not such
Taxes or Other Taxes were correctly or legally asserted. This indemnification
shall be made within 30 days from the date such Lender, such Swing Line Bank
or the Administrative Agent (as the case may be) makes written demand
therefor.

                  (d) Within 30 days after the date of any payment of Taxes, the
applicable Borrower will furnish to the Administrative Agent, at its address
referred to in Section 8.02, the original or a certified copy of a receipt
evidencing payment thereof. If any payment hereunder is to be made by a Borrower
through an account or branch outside the United States or on behalf of a
Borrower by a payor that is not a United States person and if no taxes are
payable with respect to such payment, such Borrower will, upon the request of
the Majority Lenders, furnish, or will cause the payor to furnish, to the
Administrative Agent, at such address, a certificate from each appropriate
taxing authority, or an opinion of counsel acceptable to the Administrative
Agent, in either case stating that such payment is exempt from or not subject
to Taxes. For purposes of this subsection (d) and subsection (e), the terms
"United States" and "United States person" shall have the meanings specified
in Section 7701 of the Internal Revenue Code of 1986, as amended.

                  (e) Each Lender that is organized under the laws of any
jurisdiction other than the United States of America or any political
subdivision thereof (a "Non-U.S. Lender") shall deliver to the Borrowers and the
Administrative Agent (i) two copies of either United States Internal Revenue
Service Form W-8BEN or Form W-8ECI or (ii) in the case of a Non-U.S. Lender
claiming exemption from Federal withholding tax under Section 871(h) or 881(c)
of the United States Internal Revenue Code (the "Code") with respect to payments
of "portfolio interest", a Form W-8BEN or any successor form accompanied by a
certificate representing that such Non-U.S. Lender is not a bank for purposes of
Section 881(c) of the Code, is not a ten percent shareholder of either Borrower
within the meaning of 871(h)(3)(B) of the Code and is not a controlled foreign
corporation related to either Borrower within the meaning of Section 864(d)(4)
of the Code. Such forms shall be properly executed and delivered to the
Borrowers on or before the date upon which such Non-U.S. Lender becomes a party
to this Agreement (or, in the case of a Non-U.S. Lender that is an assignee or
participant, on or before the date of assignment or transfer) or, in the event
that such Non-U.S. Lender changes its applicable lending office, the date such
new lending office is designated. In addition, each Non-U.S. Lender shall
deliver successor forms promptly upon the obsolescence or invalidity of any form
previously delivered by such Non-U.S. Lender.

                  (f) For any period with respect to which a Lender has failed
to provide a Borrower with the appropriate form described in Section 2.14(e)
(OTHER THAN if such failure is due to a change in law occurring subsequent to
the date on which a form originally was required to be provided, or if such form
otherwise is not required under the first sentence of subsection (e) above),
such Lender shall not be entitled to indemnification under Section 2.14(c) with
respect to Taxes imposed by the United States; PROVIDED, HOWEVER, that, should a
Lender become subject to Taxes because of its failure to deliver a form required
hereunder, the applicable Borrower shall take such steps (at the expense of such
Lender) as such Lender shall reasonably request to assist such Lender to recover
such Taxes.

                  (g) Subject to compliance with Section 8.07, in the event that
a Lender that originally provided such form as may be required under Section
2.14(e) thereafter

<Page>

                                                                              27

ceases to qualify for complete exemption from United States withholding tax,
such Lender may assign its interest under this Agreement to any assignee and
such assignee shall be entitled to the same benefits under this Section 2.14
as the assignor provided that (i) the rate of United States withholding tax
applicable to such assignee shall not exceed the rate then applicable to the
assignor and (ii) in the reasonable judgment of such Lender, such assignment
will not subject such Lender to any unreimbursed cost or be otherwise
disadvantageous to such Lender.

                  (h) Any Lender claiming any additional amounts payable
pursuant to this Section 2.14 shall use reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Eurodollar Lending Office if the making of such a change
would avoid the need for, or reduce the amount of, any such additional amounts
that may thereafter accrue and would not, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender.

                  (i) Without prejudice to the survival of any other agreement
of the Borrowers hereunder, the agreements and obligations of the Borrowers
contained in this Section 2.14 shall survive the payment in full of principal
and interest hereunder.

                  SECTION 2.15. SHARING OF PAYMENTS, ETC. If any Lender shall
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) on account of the Revolving Credit Advances made
by it (other than pursuant to Section 2.03(b), 2.08, 2.11, 2.14, 2.16 or 2.18)
to either Borrower in excess of its ratable share of payments on account of the
Revolving Credit Advances to such Borrower obtained by all the Lenders, such
Lender shall forthwith purchase from the other Lenders such participations in
the Revolving Credit Advances to such Borrower made by them as shall be
necessary to cause such purchasing Lender to share the excess payment ratably
with each of them; PROVIDED, HOWEVER, that, if all or any portion of such excess
payment is thereafter recovered from such purchasing Lender, such purchase from
each Lender shall be rescinded and such Lender shall repay to the purchasing
Lender the purchase price to the extent of such recovery together with an amount
equal to such Lender's ratable share (according to the proportion of (i) the
amount of such Lender's required repayment to (ii) the total amount so recovered
from the purchasing Lender) of any interest or other amount paid or payable by
the purchasing Lender in respect of the total amount so recovered. The foregoing
provisions shall apply equally to payments obtained in respect of Unrefunded
Swing Line Advance participations held by the Lenders pursuant to Section
2.01(b)(iii), with the same effect as if each reference in the immediately
preceding sentence to "Revolving Credit Advances" of a Borrower were a reference
to participations in Unrefunded Swing Line Advances of such Borrower. Each
Borrower agrees that any Lender so purchasing a participation from another
Lender pursuant to this Section 2.15 may, to the fullest extent permitted by
law, exercise all its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of such Borrower in the amount of such participation.

                  SECTION 2.16. SUBSTITUTION OF LENDERS. If (i) any Lender shall
request payment by a Borrower of any amounts payable by such Borrower pursuant
to Section 2.11 or 2.14 and at such time additional amounts payable by a
Borrower to such Lender pursuant to Section 2.11 or 2.14 shall continue to
accrue or (ii) any Lender's obligation to make Eurodollar Rate Advances shall be
suspended pursuant to Section 2.12, then, in each case, the Borrowers may demand
that such Lender assign its rights and obligations hereunder to one or more
Eligible Assignees selected by the Borrowers in accordance with Section 8.07;
PROVIDED, HOWEVER, that no Lender shall

<Page>

                                                                              28

be obligated to make any such assignment as a result of a demand by the
Borrowers unless and until such Lender shall have received one or more
payments from the Borrowers or one or more Eligible Assignees in an aggregate
amount at least equal to the aggregate outstanding principal amount of the
Advances owing to such Lender, together with accrued interest and accrued
fees thereon to the date of payment of such principal amount and all other
amounts payable to such Lender under this Agreement.

                  SECTION 2.17. USE OF PROCEEDS. The proceeds of the Advances
shall be available (and each Borrower agrees that it shall use such proceeds)
for general corporate purposes outside of Switzerland.

                  SECTION 2.18. EXTENSION OF TERMINATION DATE AND MATURITY DATE.
(a) The Borrowers may, by delivery to the Administrative Agent of a written
request of extension (a "Request of Extension") in substantially the form of
Exhibit C, given no earlier than 45 days and no later than 30 days prior to May
24, 2002 (the "First Extension Date") and, if the Termination Date shall have
been extended pursuant hereto on the First Extension Date, May 23, 2003 (the
"Second Extension Date"; and together with the First Extension Date, each an
"Extension Date"), respectively, request that each Lender agree to extend the
Termination Date applicable to its Commitment by, in the case of the First
Extension Date, 364 days and, in the case of the Second Extension Date, an
additional 364 days. Each Lender shall respond by returning a completed Request
of Extension to the Administrative Agent no earlier than 30 days and no later
than 15 days prior to the Extension Date identified in such Request of
Extension, and the Administrative Agent shall promptly but in no event later
than such 10th day prior to such Extension Date, notify the Borrowers as to each
Lender's response. A failure on the part of any Lender to return a completed
Request of Extension hereunder shall be deemed a rejection by such Lender of
such Request of Extension. If on the 10th day prior to the Extension Date
identified in such Request of Extension, the Majority Lenders (determined as of
such 10th day) shall have agreed to such extension, then the Termination Date
shall, on such Extension Date, become the date which is 364 days from such
Extension Date and the Maturity Date shall become the date which is one year
after such new Termination Date, in each case as to each Lender which agreed to
such extension; PROVIDED, HOWEVER, that such extension of the Termination Date
and the Maturity Date shall not become effective as to any Lender which did not
agree to such extension. If on such 10th day the Majority Lenders (determined as
of such 10th day) shall not have agreed to such extension, such extension shall
not become effective as to any Lender.

                  (b) If on the 10th day referred to above, the Majority Lenders
(determined as of such 10th day) have approved such extension, but any Lender
has notified the Administrative Agent that such Lender does not agree to an
extension requested by a Request of Extension, the Borrowers may demand such
Lender to assign, pursuant to Section 8.07, all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitment and the Advances owing it) to an Eligible Assignee,
with such assignment to be consummated before the 5th day prior to such
Extension Date identified in such Request of Extension; PROVIDED, HOWEVER,
that no Lender shall be obligated to make any such assignment as a result of
a demand by the Borrowers unless and until such Lender shall have received
one or more payments from the applicable Borrowers or one or more Eligible
Assignees in an aggregate amount at least equal to the aggregate outstanding
principal amount of the Advances owing to such Lender, together with accrued
interest and accrued fees thereon to the date of payment of such principal
amount and all other amounts payable to such Lender under this Agreement.

                  SECTION 2.19. CONVERSION AND CONTINUATION OF REVOLVING CREDIT
BORROWINGS. Each Borrower shall have the right at any time upon prior
irrevocable notice to the Administrative Agent (i) not later than 11:00 a.m.,
New York City time, one Business Day prior to conversion, to convert any
Revolving Credit Borrowing of such Borrower into a Borrowing consisting of Base
Rate Advances and (ii) not later than 11:00 a.m., New York City time, three
Business Days prior to conversion or continuation, to convert any Revolving
Credit Borrowing of such Borrower into a Borrowing consisting of Eurodollar Rate
Advances or to continue any Borrowing consisting of Eurodollar Rate Advances to
such Borrower for an additional Interest Period, subject in each case to the
following:

                  (a) each conversion or continuation shall be made pro rata
         among the Lenders in accordance with the respective principal amounts
         of the Advances comprising the converted or continued Borrowing;

                  (b) less than all the outstanding principal amount of any
         Borrowing may be converted or continued, but in such case the aggregate
         principal amount of such Borrowing converted or continued shall be an
         integral multiple of $5,000,000 and not less than $25,000,000;

                  (c) accrued interest on an Advance (or portion thereof) being
         converted shall be paid by the applicable Borrower at the time of
         conversion;

                  (d) if any Borrowing consisting of Eurodollar Rate Advances is
         converted at a time other than the end of the Interest Period
         applicable thereto, the applicable Borrower shall pay, upon demand, any
         amounts due to the Lenders pursuant to Section 8.04(c) as a result of
         such conversion;

                  (e) any portion of a Borrowing maturing or required to be
         repaid in less than one month or 30 days, respectively, may not be
         converted into or continued as a Borrowing consisting of Eurodollar
         Rate Advances;

                  (f) any portion of a Borrowing consisting of Eurodollar Rate
         Advances which cannot be continued as such by reason of clause (e)
         above shall be automatically converted at the end of the Interest
         Period in effect for such Borrowing into a Revolving Credit Borrowing
         consisting of Base Rate Advances;

                  (g) no Interest Period may be selected for any Borrowing that
         would end later than the Maturity Date; and

                  (h) at any time when there shall have occurred and be
         continuing any Default or Event of Default, no Borrowing may be
         converted into or continued as a Eurodollar Rate Advance.

                  Each notice pursuant to this Section 2.19 shall be irrevocable
and shall refer to this Agreement and specify (i) the identity and amount of the
Revolving Credit Borrowing that the applicable Borrower requests to be converted
or continued, (ii) the Type of Advances into which such Borrowing is to be
converted to or continued, (iii) if such notice requests a conversion, the date
of such conversion (which shall be a Business Day) and (iv) if such Borrowing is
to be converted to or continued as a Borrowing consisting of Eurodollar Rate
Advances, the Interest Period with respect thereto. If no Interest Period is
specified in any such notice with respect to any conversion to or continuation
as a Borrowing consisting of Eurodollar Rate

                                                                              30

Advances, the applicable Borrower shall be deemed to have selected an
Interest Period of one month's duration. The Administrative Agent shall
advise the other Lenders of any notice given pursuant to this Section 2.19
and of each Lender's portion of any converted or continued Borrowing. If the
applicable Borrower shall not have given notice in accordance with this
Section to continue any Borrowing into a subsequent Interest Period (and
shall not otherwise have given notice in accordance with this Section to
convert such Borrowing), such Borrowing shall, at the end of the Interest
Period applicable thereto (unless repaid pursuant to the terms hereof),
automatically be continued into a new Interest Period as a Base Rate
Borrowing.

                  SECTION 3.02. CONDITIONS PRECEDENT TO EACH BORROWING. The
obligation of each Lender to make an Advance on the occasion of each Borrowing
(including the initial Borrowing) and the obligation of the Swing Line Banks to
make Swing Line Advances hereunder shall be subject to the further conditions
precedent that on the date of such Borrowing: (a) the following statements shall
be true (and each of the giving of the applicable Notice of Borrowing and the
acceptance by the applicable Borrower of the proceeds of such Borrowing shall
constitute a representation and warranty by such Borrower that on the date of
such Borrowing such statements (other than any such statements with respect to
representations and warranties made by the other Borrower) are true):

                  (i) The representations and warranties contained in Article

         that contained in Section 4.01(l)) are correct on and as of the date of

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

                  SECTION 4.01. REPRESENTATIONS AND WARRANTIES OF THE BORROWERS.
Each Borrower represents and warrants as follows:

                  (a) Such Borrower and each of its Principal Subsidiaries (i)
         is duly organized, validly existing and in good standing under the laws
         of the jurisdiction of its incorporation (or, if not a corporation, the
         jurisdiction of its organization), (ii) has all corporate power (or, in
         the case of any such Principal Subsidiary which is not a corporation,
         has all necessary power) to own its property and carry on its business
         as now being conducted and (iii) is duly qualified to do business and
         is in good standing in each jurisdiction in which it owns or leases
         property or in which the conduct of its business requires it to so
         qualify or be licensed except to the extent that failure to so qualify
         (or be so licensed or registered) does not and is not reasonably likely
         to have a material adverse effect on the consolidated financial
         condition or operations of the Guarantor and its Subsidiaries.

                  (b) The execution, delivery and performance by such Borrower
         of this Agreement are within such Borrower's corporate powers, have
         been duly authorized by all necessary corporate action, and do not and
         will not (i) contravene such Borrower's charter or by-laws, (ii)
         violate any law, rule, regulation, order, writ, judgment, injunction,
         decree, determination or award, (iii) conflict with or result in the

         any restrictions on such Borrower's ability to, directly or indirectly,
         acquire the voting stock of a company or engage in investment banking

                  (e) PREPAYMENTS, ETC. OF SUBORDINATED DEBT. Prepay, redeem,
         purchase, defease or otherwise satisfy prior to the scheduled maturity
         thereof, or make any payment in violation of any subordination terms
         of, any Debt which is subordinated in right of payment to the
         obligations of such Borrower under this Agreement at any time when (i)
         an Advance is outstanding hereunder or (ii) any interest, fees or other
         amounts are due and payable by such Borrower hereunder; PROVIDED,
         HOWEVER, that such limitation shall not apply to the prepayment,
         redemption, purchase or defeasance by such Borrower of any subordinated
         medium-term note or other such subordinated debt if such Borrower
         immediately reissues subordinated Debt in a principal amount equal to
         or greater than the amount of such subordinated debt so prepaid,
         redeemed, purchased or defeased and such reissued subordinated Debt (A)
         is subordinated in right of payment to the Debt under this Agreement on
         terms no less favorable to the Lenders than the Debt being so prepaid,
         redeemed, purchased or defeased and (B) does not mature prior to the
         stated maturity of, and has an average life equal to or greater than,

         extensions of credit to Credit Suisse Group or any Subsidiary of Credit
         Suisse Group; PROVIDED, HOWEVER, that so long as no Event of Default
         shall have occurred and be continuing (i) such Borrower may make loans,
         advances or other extensions of credit to any Subsidiary of Credit
         Suisse Group (other than a Subsidiary of such Borrower) on terms no
         less favorable to such Borrower than it would obtain in a comparable
         arm's-length transaction in the ordinary course of business and (ii)
         such Borrower may make loans, advances or other extensions of credit to
         any of its Subsidiaries so long as such loans, advances or other
         extensions of credit bear interest at a rate consistent with reasonable
         business practices.

                  (g) DEBT. Create or suffer to exist any Debt other than Debt
         which ranks PARI PASSU with, or subordinate in right of payment to, the

         wholly-owned Subsidiary of CSFB (USA) and a registered broker-dealer.

         Borrower or the Guarantor shall fail to perform or observe any other
         term, covenant or agreement contained in this Agreement or the
         Guarantee on its part to be performed or observed if the failure to
         perform or observe such other term, covenant or agreement shall remain
         unremedied for 21 days after written notice thereof shall have been
         given to the Guarantor or, as the case may be, by the Administrative
         Agent or any Lender; or

                  (d) Any one or more of the Guarantor, the Borrowers and the

         bankrupt or insolvent, or seeking liquidation, winding up,

Event of Default), whereupon the Advances, all such interest and all such
amounts shall become and be forthwith due and payable, without presentment,
demand, protest or further notice of any kind, all of which are hereby
expressly waived by the Borrowers, and (z) the obligations of the Lenders to
make Advances to any Borrower in respect of which the lending obligations

                            THE ADMINISTRATIVE AGENT

                  Subject to the further provisions of this Article VII, each of
the Lenders and each Swingline Bank hereby irrevocably appoints the
Administrative Agent as its agent and authorizes the Administrative Agent to
take such actions on its behalf and to exercise such powers as are delegated to
the Administrative Agent by the terms hereof, together with such actions and
powers as are reasonably incidental thereto.

                  The bank serving as the Administrative Agent hereunder shall
have the same rights and powers in its capacity as a Lender as any other Lender
and may exercise the same as though it were not the Administrative Agent, and
such bank and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrowers or their
Subsidiaries or other Affiliate thereof as if it were not the Administrative
Agent hereunder.

                  The Administrative Agent shall not have any duties or
obligations except those expressly set forth herein. Without limiting the
generality of the foregoing, (a) the Administrative Agent shall not be subject
to any fiduciary or other implied duties, regardless of whether a Default has
occurred and is continuing, (b) the Administrative Agent shall not have any duty
to take any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated hereby that the
Administrative Agent is required to exercise in writing by the Majority Lenders
(or such other number or percentage of the Lenders as shall be necessary under
the circumstances as provided in Section 8.01), and (c) except as expressly set
forth herein, the Administrative Agent shall not have any duty to disclose, and
shall not be liable for the failure to disclose, any information relating to the
Guarantor, the Borrowers or any of their Subsidiaries that is communicated to or
obtained by the bank serving as Administrative Agent or any of its Affiliates in
any capacity (other than as Administrative Agent). The Administrative Agent
shall not be liable for any action taken or not taken by it with the consent
or at the request of the Majority Lenders (or such other number or percentage
of the Lenders as shall be necessary under the circumstances as provided in
Section 8.01) or in the absence of its own gross negligence or wilful
misconduct. The Administrative Agent shall be deemed not to have knowledge of
any Default unless and until written notice thereof is given to the
Administrative Agent by the applicable Borrower or a Lender, and the
Administrative Agent shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made
by any other Person in or in connection with this Agreement, (ii) the
contents of any certificate, report or other document delivered hereunder or
in connection herewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein, (iv) the
validity, enforceability, effectiveness (other than its own execution) or
genuineness of this Agreement or any other agreement, instrument or document,
or (v) the satisfaction of any condition set forth in Article III or
elsewhere herein, other than to confirm receipt of items expressly required
to be delivered to the Administrative Agent.

                  The Administrative Agent shall be entitled to rely upon, and
shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing
reasonably believed by it to be genuine and to have been signed or sent by the
proper Person. The Administrative Agent also may rely upon any statement made to
it orally or by telephone and believed by it to be

                                                                              44

made by the proper Person, and shall not incur any liability for relying
thereon. The Administrative Agent may consult with legal counsel (who may be
counsel for either Borrower or the Guarantor), independent accountants and
other experts selected by it, and shall not be liable for any action taken or
not taken by it in accordance with the advice of any such counsel,
accountants or experts.

                  The Administrative Agent may perform any and all its duties
and exercise its rights and powers by or through any one or more sub-agents
appointed by the Administrative Agent. The Administrative Agent and any such
sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Affiliates. The exculpatory provisions of the preceding
paragraphs shall apply to any such sub-agent and to the Affiliates of the
Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided
for herein as well as activities as Administrative Agent.

                  Subject to the appointment and acceptance of a successor
Administrative Agent as provided in this paragraph, the Administrative Agent may
resign at any time by notifying the Lenders, the Swingline Banks and the
Borrowers. Upon any such resignation, the Majority Lenders shall have the right,
subject to the approval of the Borrowers (provided no Event of Default exists),
to appoint a successor. If no successor shall have been so appointed by the
Majority Lenders and shall have accepted such appointment within 30 days after
the retiring Administrative Agent gives notice of its resignation, then the
retiring Administrative Agent may, on behalf of the Lenders and the Swingline
Banks, appoint a successor Administrative Agent which shall be a bank with an
office in New York, New York, or an Affiliate of any such bank. Upon the
acceptance of its appointment as Administrative Agent hereunder by a
successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent,
and the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. The fees payable by the Borrowers to a successor
Administrative Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Borrowers and such successor. After the
Administrative Agent's resignation hereunder, the provisions of this Article
and Section 8.04 shall continue in effect for the benefit of such retiring
Administrative Agent, its sub-agents and their respective Related Parties in
respect of any actions taken or omitted to be taken by any of them while it
was acting as Administrative Agent.

                  Each Lender acknowledges that it has, independently and
without reliance upon the Administrative Agent or any other Lender and based on
such documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges 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 from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder or thereunder.

provision of this Agreement, nor consent to any departure by a Borrower
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Majority Lenders and each Borrower, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; PROVIDED, HOWEVER, that no amendment, waiver or consent
shall, unless in writing and signed by all the Lenders, do any of the following:

Lenders" or the percentage of the Commitments or of the aggregate unpaid

Swing Line Banks or any of them to take any action hereunder, (f) modify the
second, third or fourth sentence of Section 2.13, Section 2.15 or any other
provision providing for the equal or ratable treatment of the Lenders or (g)
amend this Section 8.01; PROVIDED FURTHER, HOWEVER, that no amendment, waiver or
consent shall, unless in writing and signed by (i) the Administrative Agent in
addition to the Lenders required above to take such action, affect the rights or
duties of the Administrative Agent under this Agreement or (ii) a Swing Line
Bank in addition to the Lenders required above to take such action, increase
such Swing Line Bank's Swing Line Commitment or otherwise affect the rights or
obligations of such Swing Line Bank hereunder.

                  SECTION 8.02. NOTICES, ETC. All notices and other
communications provided for hereunder shall be in writing (including telecopier
communication) and mailed, telecopied or delivered, to each Borrower at its

any Lender, any Swing Line Bank or the Administrative Agent to exercise, and no
delay in exercising, any right hereunder shall operate as a waiver thereof;
nor shall any single or partial exercise of any such right preclude any other
or further exercise thereof or the exercise of any other right. The remedies
herein provided are cumulative and not exclusive of any remedies provided by
law.

                                                                              46

                  SECTION 8.04. COSTS, EXPENSES AND TAXES. (a) The Borrowers
agree, jointly and severally, to pay on demand all costs and expenses in
connection with the syndication of the credit facilities provided for herein and
the preparation, execution, delivery, administration, modification and amendment
of this Agreement and the other documents to be delivered hereunder, including,
without limitation, the reasonable fees and out-of-pocket expenses of counsel
for the Administrative Agent with respect thereto and with respect to advising
the Administrative Agent as to its rights and responsibilities under this
Agreement. The Borrowers further agree, jointly and severally, to pay on demand
all costs and expenses, if any (including, without limitation, reasonable fees
and expenses of counsel for the Administrative Agent and the Lenders hereunder),
in connection with the enforcement (whether through negotiations, legal
proceedings or otherwise) of this Agreement and the other documents to be
delivered hereunder, including, without limitation, reasonable fees and expenses
of counsel for the Administrative Agent and the Lenders hereunder in connection
with the enforcement of rights under this Section 8.04(a).

                  (b) The Borrowers agree, jointly and severally, to indemnify
and hold harmless the Administrative Agent, each Swing Line Bank and each Lender
and each of their Affiliates and their officers, directors, employees, agents
and advisors (each, an "Indemnified Party") from and against any and all claims,
damages, losses, liabilities and expenses (including, without limitation,
reasonable fees and expenses of counsel) that may be incurred by or asserted or
awarded against any Indemnified Party, in each case arising out of or in
connection with or by reason of, or in connection with an Event of Default or
with the preparation for a defense of, any investigation, litigation or
proceeding arising out of, related to or in connection with this Agreement,
including, without limitation, any transaction in which the proceeds of any
Borrowing hereunder are or are to be applied, whether or not an Indemnified
Party is a party thereto and whether or not the transactions contemplated hereby
are consummated, except to the extent any such claim, damage, loss, liability or
expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnified Party's gross negligence or
willful misconduct.

                  (c) If any payment, prepayment or conversion of any Eurodollar
Rate Advance or Fixed Rate Advance is made other than on the last day of the
Interest Period for such Advance, as a result of a payment pursuant to Section
2.10 or 2.12, a conversion of a Revolving Credit Advance pursuant to Section
2.19, acceleration of the maturity of the Advances pursuant to Section 6.01 or
for any other reason, the applicable Borrower shall, upon demand by any Lender
(with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender any amounts required to
compensate such Lender for any additional losses, costs or expenses which it may
reasonably incur as a result of such payment, including, without limitation, any
loss (including loss of anticipated profits), cost or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired
by any Lender to fund or maintain such Advance. In the event of the failure
to borrow, convert, continue or prepay any Revolving Credit Advance on the
date specified in any notice delivered pursuant hereto, the failure to borrow
any Auction Bid Advance after accepting the Auction Bid to make such Advance
or the assignment of any Advance other than on the last day of the Interest
Period applicable thereto as a result of a request by the Borrowers pursuant
to Section 2.16, 2.18(b) or 8.07(a), then, in any such event, the applicable
Borrower shall, upon demand by any Lender (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of
such Lender any amounts required to compensate such Lender for any additional
losses, costs or expenses which it may reasonably incur as a result of such
event, including, without limitation, any loss

                                                                              47

(including loss of anticipated profits), cost or expense incurred by reason
of the liquidation or reemployment of deposits or other funds acquired by any
Lender to fund or maintain such Advance. A certificate as to the amount of
such losses, costs or expenses submitted to the applicable Borrower and the
Administrative Agent by such Lender shall be conclusive and binding for all
purposes, absent manifest error.

                  SECTION 8.05. RIGHT OF SET-OFF. Upon (i) the occurrence and
during the continuance of any Event of Default and (ii) the making of the
request or the granting of the consent specified by Section 6.01 to authorize
the Administrative Agent to declare the Advances due and payable pursuant to the
provisions of Section 6.01, each Lender and each Swing Line Bank is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender or such Swing Line Bank to or for the credit or the
account of the applicable Borrower against any and all of the obligations of
such Borrower now or hereafter existing under this Agreement and any Advances
held by such Lender or such Swing Line Bank, whether or not such Lender or such
Swing Line Bank shall have made any demand under this Agreement and although
such obligations may be unmatured. Each Lender and each Swing Line Bank agrees
promptly to notify the applicable Borrower after any such set-off and
application made by such Lender or such Swing Line Bank; PROVIDED, HOWEVER, that
the failure to give such notice shall not affect the validity of such set-off
and application. The rights of each Lender and each Swing Line Bank under this
Section are in addition to other rights and remedies (including, without
limitation, other rights of set-off) which such Lender or such Swing Line Bank
may have.

                  SECTION 8.06. BINDING EFFECT. This Agreement shall become
effective in accordance with Section 3.01 and thereafter shall be binding upon
and inure to the benefit of the Borrowers, the Administrative Agent, each Swing
Line Bank and each Lender and their respective successors and assigns, except
that the Borrowers shall not have the right to assign their rights hereunder or
any interest herein without the prior written consent of the Lenders and the
Swing Line Banks.

                  SECTION 8.07. ASSIGNMENTS AND PARTICIPATIONS. (a) Each Lender
may and, if demanded by the Borrowers (pursuant to Section 2.16 or 2.18(b)) upon
at least five Business Days' notice to such Lender and the Administrative Agent,
will assign to one or more banks or other entities all or a portion of its
rights and obligations under this Agreement (including, without limitation, all
or a portion of its Commitment and the Advances owing to it); PROVIDED, HOWEVER,
that (i) each such assignment shall be of a constant, and not a varying,
percentage of all rights and obligations under this Agreement, (ii) the amount
of the Commitment of the assigning Lender being assigned pursuant to each such
assignment (determined as of the date of the Assignment and Acceptance with
respect to such assignment) shall in no event be less than $10,000,000 (or
$5,000,000, in the case of an assignment to a Lender Affiliate) or the remaining
amount of such Lender's Commitment and shall be an integral multiple of
$500,000, (iii) each such assignment shall be to a Lender, a Lender Affiliate, a
Person described in clause (viii) of the definition of "Eligible Assignee" in
Section 1.01 or, with the consent of the Borrowers (such consent not to be
unreasonably withheld), any other Eligible Assignee, (iv) each such assignment
made as a result of a demand by the Borrowers pursuant to this Section 8.07(a)
shall be arranged by the Borrowers after consultation with the Administrative
Agent and shall be either an assignment of all of the rights and obligations of
the assigning Lender under this Agreement or an assignment of a portion of such
rights and obligations made concurrently with another such assignment or other
such

<Page>

                                                                              48

assignments that together cover all of the rights and obligations of the
assigning Lender under this Agreement, (v) no Lender shall be obligated to make
any such assignment as a result of a demand by the Borrowers pursuant to this
Section 8.07(a) unless and until such Lender shall have received one or more
payments from either the Borrowers or one or more Eligible Assignees in an
aggregate amount at least equal to the aggregate outstanding principal amount of
the Advances owing to such Lender, together with accrued interest thereon to the
date of payment of such principal amount and all other amounts payable to such
Lender under this Agreement and (vi) the parties to each such assignment shall
execute and deliver to the Administrative Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, together with a
processing and recordation fee of $3,500 (or $1,000, in the case of an
assignment to a Lender Affiliate); PROVIDED, HOWEVER, that, if such assignment
is made as a result of a demand by the Borrowers pursuant to this Section
8.07(a), the Borrowers shall pay or cause to be paid such fee. Upon such
execution, delivery, acceptance and recording, from and after the effective date
specified in each Assignment and Acceptance, (x) the assignee thereunder shall
be a party hereto and, to the extent that rights and obligations hereunder have
been assigned to it pursuant to such Assignment and Acceptance, have the rights
and obligations of a Lender hereunder and (y) the Lender assignor thereunder
shall, to the extent that rights and obligations hereunder have been assigned by
it pursuant to such Assignment and Acceptance, relinquish its rights (other than
any such rights which by their terms survive the termination of this Agreement
or the payment in full of principal and interest hereunder) and be released from
its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto (other than with respect to any such rights which by their terms
survive the termination of this Agreement or the payment in full of principal
and interest hereunder)). Notwithstanding the foregoing, any Lender assigning
its rights and obligations under this Agreement may retain any Auction Bid
Advances made by it, outstanding at such time, and in such case shall retain
its rights hereunder in respect of any Advances so retained until such
Advances have been repaid in full in accordance with this Agreement.

                  (b) By executing and delivering an Assignment and Acceptance,
the Lender assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document
furnished pursuant hereto; (ii) such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of the Borrowers or the Guarantor or the performance or observance by the
Borrowers or the Guarantor of any of their obligations under this Agreement or
the Guarantee or any other instrument or document furnished pursuant hereto;
(iii) such assignee confirms that it has received a copy of this Agreement and
the Guarantee, together with copies of the financial statements referred to in
Section 5.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Administrative Agent, such assigning Lender 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 decisions in taking or not taking
action under this Agreement; (v) such assignee confirms that it is an Eligible
Assignee; (vi) such

<Page>

                                                                              49

assignee appoints and authorizes the Administrative Agent to take such action
as agent on its behalf and to exercise such powers under this Agreement as
are delegated to the Administrative Agent by the terms hereof, together with
such powers as are reasonably incidental thereto; and (vii) such assignee
agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed
by it as a Lender.

                  (c) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an assignee representing that it is an Eligible
Assignee, the Administrative Agent shall, if such Assignment and Acceptance has
been completed and is in substantially the form of Exhibit E hereto, (i) accept
such Assignment and Acceptance, (ii) record the information contained therein in
the Register and (iii) give prompt notice thereof to the Borrowers.

                  (d) The Administrative Agent shall maintain at its address
referred to in Section 8.02 a copy of each Assignment and Acceptance delivered
to and accepted by it and a register for the recordation of the names and
addresses of each of the Lenders and, with respect to Lenders, the Commitment
of, and principal amount of the Advances owing to, each such Lender from time
to time (the "Register"). The entries in the Register shall be conclusive and
binding, absent manifest error, and the Borrowers, the Administrative Agent
and the Lenders may treat each Person whose name is recorded in the Register
as a Lender hereunder for the purposes of this Agreement. The Register shall
be available for inspection by the Borrowers or any Lender at any reasonable
time and from time to time upon reasonable prior notice.

                  (e) Each Lender may sell participations to one or more banks
or other entities in or to all or a portion of its rights and obligations under
this Agreement (including, without limitation, all or a portion of its
Commitment and the Advances owing to it); PROVIDED, HOWEVER, that (i) such
Lender's obligations under this Agreement (including, without limitation, its
Commitment to the Borrowers hereunder) shall remain unchanged, (ii) such Lender
shall remain solely responsible to the other parties hereto for the performance
of such obligations, (iii) such Lender shall remain the holder of any such
Advances for all purposes of this Agreement, (iv) the Borrowers, the
Administrative Agent, the Swing Line Banks and the other Lenders shall continue
to deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement and (v) such Lender shall not sell a
participation pursuant to this Section 8.07(e) to any bank or other entity which
is not a Lender, a Lender Affiliate or a Person described in clause (viii) of
the definition of "Eligible Assignee" in Section 1.01 without the consent of the
Borrowers, such consent not to be unreasonably withheld. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification or waiver of any provision of this
Agreement; PROVIDED, HOWEVER, that such agreement or instrument may provide that
such Lender will not, without the consent of the participant, agree to any
amendment, modification or waiver described in the first proviso to Section 8.01
that affects such participant. Subject to paragraph (f) of this Section, the
Borrowers agree that each participant shall be entitled to the benefits of
Sections 2.03(b), 2.11, 2.14 and 8.04(c) to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to paragraph (b) of
this Section. To the extent permitted by law, each participant also shall be
entitled to the benefits of Section 8.05 as though it were a Lender, provided
such participant agrees to be subject to Section 2.15 as though it were a
Lender.

                                                                              50

                  (f) A participant shall not be entitled to receive any greater
payment under Section 2.11 or 2.14 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such participant,
unless the sale of the participation to such participant is made with the
Borrowers' prior written consent. A participant that is organized under the laws
of a jurisdiction outside the United States shall not be entitled to the
benefits of Section 2.14 unless the Borrowers are notified of the participation
sold to such participant and such participant agrees, for the benefit of the
Borrowers, to comply with Section 2.14(e) as though it were a Lender.

                  (g) Any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
8.07, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrowers furnished to such Lender
by or on behalf of the Borrowers; PROVIDED, HOWEVER, that, prior to any such
disclosure, the assignee or participant or proposed assignee or participant
shall agree to preserve the confidentiality of any Confidential Information
relating to the Borrowers received by it from such Lender on terms substantially
the same as those applicable to such Lender under Section 8.08.

                  (h) Notwithstanding any other provision set forth in this
Agreement, any Lender may at any time create a security interest in all or any
portion of its rights under this Agreement (including, without limitation, the
Advances owing to it) in favor of any Federal Reserve Bank in accordance with
Regulation A of the Board of Governors of the Federal Reserve System, and each
Borrower will, if requested, issue a note to be pledged to such Federal Reserve
Bank evidencing its obligations in respect of principal of and interest on
Advances of such Lender hereunder.

                  (i) Except as expressly provided in this Agreement, the Swing
Line Banks may not assign or delegate any of their respective rights and duties
hereunder without the prior written consent of the Borrowers and the
Administrative Agent.

                  (j) Prior to any assignment to, or purchase of a participation
by, any employee benefit plan or any entity the assets of which would be
considered "plan assets" within the meaning of U.S. Department of Labor
regulations (29 CFR ss. 2510.3-101, or any successor thereto) (together referred
to herein as "employee benefit plans") of any rights and obligations under this
Agreement, each such employee benefit plan or other such entity shall represent
to the Borrowers that the holding of any such assignment or the purchase and
holding of any such participation hereunder by such plan or other entity is
exempt from the prohibited transaction rules of ERISA and the Internal Revenue
Code of 1986, as amended from time to time. This representation shall be made on
each date from and including the date of any assignment or purchase of any
participation and through the date of disposition thereof.

                  SECTION 8.08. CONFIDENTIALITY. None of the Administrative
Agent or any Lender shall disclose any Confidential Information to any Person
without the consent of the Borrowers, other than (a) to the Administrative
Agent's or such Lender's Affiliates and its and their officers, directors,
employees, agents and advisors and to actual or prospective Eligible Assignees
and participants, and then only on a confidential basis, (b) as required by any
law, rule or regulation or judicial process and (c) as requested or required by
any state, federal or foreign authority or examiner regulating banks or banking.

                  SECTION 8.09. PARITY. If at any time hereafter either Borrower
shall enter into a Similar Credit Agreement (i) that shall contain a term or
condition (not including any such term or condition which would otherwise be
subject to this clause (i) but relates to the matters as are covered herein
by Section 2.03 or the definition of "Applicable Rate" in Section 1.01) which
a reasonable Person would conclude is favorable to a lender and that is not
contained in this Agreement or (ii) that shall contain a modification of a
term or condition (not including any such term or condition which would
otherwise be subject to this clause (ii) but relates to the matters as are
covered herein by Section 2.03 or the definition of "Applicable Rate" in
Section 1.01) contained herein, which a reasonable Person would conclude is
more favorable to a lender than the term or condition as set forth herein,
then such Borrower will promptly notify the Administrative Agent and the
Lenders of such term or condition (or modification thereof) and, at the
request of the Majority Lenders, shall agree to an amendment of this
Agreement so that it shall contain such a term or condition or modification,
as the case may be, applicable to such Borrower. "Similar Credit Agreement"
means a committed senior unsecured bank credit agreement or similar agreement
with respect to indebtedness for money borrowed (which shall not be deemed to
include letter of credit facilities) (i) which has an initial commitment
termination date of 364 days or less, (ii) the proceeds of which may be used
by a Borrower for the same purposes the proceeds hereunder are permitted to
be used by such Borrower under Section 2.16 and (iii) which contains terms
and conditions which, when taken as a whole, have similar or comparable
import and effect on the relevant Borrower and its Subsidiaries as the terms
and conditions contained in Section 6.01(j).

                  SECTION 8.10. SURVIVAL. All covenants, agreements,
representations and warranties made by the Borrowers and the Principal
Subsidiaries herein and in the certificates or other instruments delivered in
connection with or pursuant to this Agreement shall be considered to have been
relied upon by the other parties hereto and shall survive the execution and
delivery of this Agreement and the making of any Advances, regardless of any
investigation made by any such other party or on its behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default or incorrect representation or warranty at the time any credit is
extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on any Advance or any fee or any other
amount payable under this Agreement is outstanding and unpaid and so long as the
Commitments have not expired or terminated. The provisions of Sections 2.11,
2.12, 2.13 and 8.04 and Article VII shall survive and remain in full force and
effect regardless of the consummation of the transactions contemplated hereby,
the repayment of the Advances and the expiration or termination of the
Commitments or the termination of this Agreement or any provision hereof.

                  SECTION 8.11. GOVERNING LAW. This Agreement shall be governed
by, and construed in accordance with, the laws of the State of New York.

                  SECTION 8.12. EXECUTION IN COUNTERPARTS. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be
an original and all of which taken together shall constitute one and the same
agreement.

                  SECTION 8.13. CURRENCY INDEMNITY. The sole currency of account
and payment for all sums payable by the Borrowers under this Agreement,
including in respect of indemnities, costs and damages, is Dollars. Any amount
received or recovered in a currency other than Dollars (whether as a result of a
judgment or order

                                                                              52

of a court of any jurisdiction, or the enforcement thereof, in the winding up
or dissolution of a Borrower or otherwise) by the Administrative Agent, or
any Lender in respect of any sum expressed to be due to it from a Borrower
shall only constitute a discharge to such Borrower to the extent of the
amount of Dollars that the recipient is able to purchase with the amount so
received or recovered in that currency on the date of that receipt or
recovery (or, if it is not practicable to make that purchase on that date, on
the first date on which it is practicable to do so). If that amount of
Dollars is less than the amount of Dollars expressed to be due to the
recipient under this Agreement, the applicable Borrower shall indemnify it
against any loss sustained by it as a result. In any event, the applicable
Borrower shall indemnify the recipient against the cost of making any such
purchase. For the purpose of this Agreement, it will be sufficient for any
recipient to demonstrate that it would have suffered a loss had an actual
purchase been made. These indemnities constitute a separate and independent
cause of action, shall apply irrespective of any indulgence granted by the
Administrative Agent or any Lender and shall continue in full force and
effect despite any other judgment, order, claim or proof for a liquidated
amount in respect of any sum due under this Agreement or any other judgment
or order.

                  SECTION 8.14. WAIVER UNDER EXISTING CREDIT AGREEMENTS. The
banks who are parties to the Existing Credit Agreements agree that their
commitments thereunder and their rights under the Guarantee Agreement (as
defined in the Existing Credit Agreement referred to in clause (i) of the
definition of such term) shall be deemed terminated upon the effectiveness of
this Agreement pursuant to Section 3.01 and hereby waive any prior notice of
such termination of their commitments under either of the Existing Credit
Agreements.

                  SECTION 8.15. WAIVER OF JURY TRIAL. EACH OF THE BORROWERS, THE
ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO
TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON
CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
GUARANTEE, THE ADVANCES OR THE ACTIONS OF THE ADMINISTRATIVE AGENT OR ANY LENDER
IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

                  SECTION 8.16. JURISDICTION; CONSENT TO SERVICE OF PROCESS. (a)
Each of the Borrowers hereby irrevocably and unconditionally submits, for itself
and its property, to the nonexclusive jurisdiction of any New York State court
or Federal court of the United States of America sitting in the Borough of
Manhattan, The City of New York, and any appellate court from any thereof, in
any suit, action or proceeding arising out of or relating to this Agreement
or any other document delivered hereunder, or for recognition or enforcement
of any judgment, and each of the parties hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the
extent permitted by law, Federal court. Each of the parties hereto agrees
that a final judgment in any such action or proceeding shall be conclusive
and may be enforced in other jurisdictions by suit on the judgment or in any
other manner provided by law. Nothing in this Agreement shall affect any
right that the Administrative Agent or any Lender may otherwise have to bring
any action or proceeding relating to this Agreement or any other document
delivered hereunder against any Borrower or any of its Subsidiaries or any of
their respective properties in the courts of any jurisdiction.

                  (b) Each of the Borrowers hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
any other document delivered hereunder in any New York State or Federal court.
Each of the parties hereto hereby irrevocably waives, to the fullest extent
permitted by law, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any such court.

                  (c) Each party to this Agreement irrevocably consents to
service of process in the manner provided for notices in Section 8.02. Nothing
in this Agreement will affect the right of any party to this Agreement to serve
process in any other manner permitted by law.

                                                                       EXHIBIT F





                        GUARANTEE AGREEMENT (this "AGREEMENT") dated as of
                   May 25, 2001, from CREDIT SUISSE GROUP, a corporation with
                   limited liability organized under the laws of Switzerland
                   (the "GUARANTOR"), in favor of the Beneficiaries (as defined
                   herein).

            Reference is made to the U.S. $3,500,000,000 364-Day Auction Bid
Advance and Revolving Credit Facility Agreement dated as of May 25, 2001 (as
amended, supplemented or modified from time to time, the "CREDIT AGREEMENT"),
among Credit Suisse First Boston, Inc. ("CSFB INC."), Credit Suisse First Boston
(USA), Inc. ("CSFB (USA)" and, together with CSFB Inc., (the "BORROWERS"), the
financial institutions party thereto, as lenders (the "Lenders"), The Chase
Manhattan Bank, as Administrative Agent (the "AGENT") and The Bank of New York,
Bank One, NA (Main Chicago Office), Citibank, N.A. and Deutsche Bank AG, New
York Branch and/or Cayman Islands Branch, as Syndication Agents (the
"SYNDICATION AGENTS").

            The Lenders have agreed to extend credit to the Borrowers pursuant
to, and subject to the terms specified in, the Credit Agreement. The obligations
of the Lenders to extend credit under the Credit Agreement are conditioned on,
among other things, the execution and delivery by the Guarantor of a guarantee
agreement in the form hereof. As the indirect or direct owner of 100% of the
issued and outstanding voting stock of each of CSFB Inc. and CSFB (USA), the
Guarantor derives substantial benefits from the extension of credit to the
Borrowers under the Credit Agreement. As consideration therefor and in order to
induce the Lenders to extend credit to the Borrowers under the Credit Agreement,
the Guarantor is willing to execute and deliver this Agreement. Accordingly, the
parties hereto agree as follows:

                                    ARTICLE I

      deferred purchase price of assets or services (other than goods or
      services obtained on normal commercial terms in the ordinary course of

                                    GUARANTEE

            SECTION 2.01. GUARANTEE. The Guarantor unconditionally and
irrevocably guarantees, as a primary obligor and not merely as a surety, the due
and punctual payment by each Borrower of (i) the principal of and premium, if
any, and interest (including interest accruing during the pendency of any
bankruptcy, insolvency, receivership or similar proceeding, regardless of
whether allowed or allowable as a claim in such proceeding) on the Advances made
to such Borrower, when and as due, whether at maturity, by acceleration, upon
one or more dates set for prepayment or otherwise, and (ii) all other monetary
obligations, including fees, costs, expenses and indemnities, of each Borrower
to the Lenders or the other Beneficiaries under the Credit Agreement (including
monetary obligations incurred during the pendency of any bankruptcy, insolvency,

as a claim in such proceeding) (all the foregoing obligations being collectively

Borrower fails to make any payment to the Beneficiaries of any or all the
Obligations when due (subject to any applicable notice or grace periods) under

shall, on or before the Business Day immediately following the date of written
demand by the Administrative Agent or any Beneficiary, pay to such Beneficiary
or to the Administrative Agent for the benefit of the Beneficiaries any
Obligations that such Borrower has failed to pay as aforesaid. Any amounts paid
by the Guarantor hereunder in respect of Advances, interest and fees shall be
applied in accordance with the terms of the Credit Agreement.

            SECTION 2.03. GUARANTEE OF PAYMENT. The Guarantor further agrees
that its guarantee hereunder constitutes a guarantee of payment when due and not
of collection, and waives any right to require that any resort be had by the
Administrative Agent or any Lender to any balance of any deposit account or
credit on the books of the Administrative Agent or any Lender in favor of either
Borrower or any other person.

            SECTION 2.04. NO DISCHARGE OR DIMINISHMENT OF GUARANTEE. The
obligations of the Guarantor hereunder shall be absolute and unconditional and
shall not be subject to any reduction, limitation, impairment or termination for
any reason, including, without limitation, any claim of waiver, release,
surrender, alteration or compromise, and shall not be subject to any defense or
setoff, counterclaim, recoupment or termination whatsoever by reason of the
invalidity, illegality or unenforceability of the Obligations or otherwise.
Without limiting the generality of the foregoing, the obligations of the
Guarantor hereunder shall not be discharged or impaired or otherwise affected
by:

            (a) the failure of the Administrative Agent or any Beneficiary to
      assert any claim or demand or to enforce any remedy under the Credit
      Agreement, any guarantee or any other agreement;

            (b) any lack of validity or enforceability of either or both
      Borrowers' obligations under the Credit Agreement;

            (c) any change in time, manner or place of payment of, or in the
      principal amount, interest rate or any other term of, any of the
      Obligations, or any other amendment or waiver of, or any consent to or
      departure from any of the terms of, the Obligations or the Credit
      Agreement;

            (d) any change in ownership or control of either or both Borrowers
      (it being expressly understood that Obligations incurred after the date of
      any such change shall continue to be covered by this Agreement to the
      extent provided in Section 2.01);

            (e) any bankruptcy, insolvency, winding up or reorganization of, or
      similar proceedings involving, either or both Borrowers; or

            (f) any other act, omission or circumstance which might constitute a
      defense available to either or both Borrowers or might in any manner or to
      any extent vary the risk of the Guarantor or otherwise operate as a
      discharge of the Guarantor as a matter of law or equity (other than the
      indefeasible payment in full of all the Obligations).

            SECTION 2.05. AVOIDANCE OF PAYMENTS. The Guarantor further agrees
that its guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time payment, or any part thereof, of principal of or
interest on any Obligation is rescinded or must otherwise be restored by the
Administrative Agent or any Beneficiary upon the bankruptcy or reorganization
of either Borrower or otherwise, all as though such payment had not been made.

            SECTION 2.06. INDEPENDENT OBLIGATIONS. The obligations of the
Guarantor hereunder are independent of the obligations of either Borrower or of
any other Person and a separate action or actions may be brought and prosecuted
against the Guarantor whether or not action is brought against either Borrower
or any other Person, and whether or not either Borrower or any other Person is
joined in such action.

                                                                               4

            SECTION 2.07. CONTINUING OBLIGATION. This Agreement constitutes a
primary obligation of the Guarantor and is a continuing obligation and shall (a)
remain in full force and effect in accordance with the terms hereof until the
Commitments shall have expired or been terminated and the Lenders shall have
received payment in full of all the Obligations and until all possibility for
the rescission or return of any payment to the Beneficiaries shall have ended,
(b) be binding upon the Guarantor and its successors and assigns and (c) inure
to the benefit of and be enforceable by the Beneficiaries and their respective
successors and permitted assigns.

            SECTION 2.08. WAIVER. Except for notices or demands expressly
required hereunder, the Guarantor hereby waives, to the extent permitted by
applicable law, (a) acceptance hereof by the Beneficiaries, (b) presentment,
demand for performance, protest, promptness, diligence, notice of acceptance,
notice of dishonor and any other notice with respect to any of the Obligations,
this Agreement or any obligation of the Guarantor hereunder and (c) any other
notices or demands of any kind.

            SECTION 2.09. SUBROGATION. The Guarantor will not exercise any
rights against either Borrower that it may acquire by way of subrogation
hereunder, by any payment made hereunder or otherwise, until the Commitments
shall have expired or been terminated with respect to such Borrower and the
Obligations shall have been paid in full. If any amount shall nevertheless be
paid to the Guarantor on account of such subrogation rights at any time prior to
the expiration or termination of the Commitments with respect to such Borrower
and payment in full of the Obligations and all of the Guarantor's payment
obligations contained in this Agreement, such amount shall be held in trust for
the benefit of the Beneficiaries and shall forthwith be paid to the
Beneficiaries or the Administrative Agent for the benefit of the Beneficiaries
and shall be credited and applied toward the Obligations in accordance with the
terms hereof and of the Credit Agreement. Subject to the foregoing, nothing
contained in this Agreement shall be deemed a waiver of the Guarantor's right of
subrogation against either Borrower.

            SECTION 2.10. TAXES. (a) Any and all payments by the Guarantor
hereunder shall be made free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, EXCLUDING, in the case of each
Beneficiary, taxes imposed to or measured by its net income, and franchise taxes
imposed on it, by the jurisdiction under the laws of which such Beneficiary is
organized or any political subdivision thereof and, in the case of each Lender,
taxes imposed on or measured by its net income, and franchise taxes imposed on
it, by the jurisdiction of such Lender's Applicable Lending Office or any
political subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "TAXES"). If the Guarantor shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder to any Beneficiary, (i) the sum
payable shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.10) such Beneficiary receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Guarantor shall make
such deductions and (iii) the Guarantor shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance with applicable
law.

stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery, enforcement or registration of, or otherwise with respect
to, this Agreement (hereinafter referred to as "OTHER TAXES").

amount of Taxes or Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section
2.10) paid by such Beneficiary and any liability (including penalties, interest
and expenses) arising therefrom or with respect thereto, whether or not such
Taxes or Other Taxes were correctly or legally asserted. This indemnification
shall be made within 30 days from the date such Beneficiary makes written demand
therefor.

            (a) liens arising solely by operation of law (or by an agreement
      evidencing the same) in the ordinary course of its business in respect of
      indebtedness which either (a) has been due for less than 30 days or (b) is
      being contested in good faith and by appropriate means;

            (b) any Encumbrance created on any asset acquired by it after the
      date of this Agreement for the purpose of financing or refinancing that
      acquisition and securing a principal, capital or nominal amount not
      exceeding the cost of that acquisition;

            (c) any other Encumbrance created or outstanding with the prior
      consent of the Majority Lenders; or

            (d) any other Encumbrance created or outstanding on or over assets
      of the Guarantor provided that the aggregate outstanding principal,
      capital or nominal amount secured by all Encumbrances created or
      outstanding under this exception on or over assets of the Guarantor does
      not at any time exceed U.S.$200,000,000 or its equivalent (for the
      avoidance of doubt, any Encumbrance on shares owned by and/or shares of
      the share capital of the Guarantor in connection with the securing of
      options ("Stillhalteroptionen") shall not be considered for the purposes
      of this paragraph (d)).

                                    ARTICLE V

            SECTION 5.01. CURRENCY INDEMNITY. The sole currency of account and
payment for all sums payable by the Guarantor under this Agreement, including in
respect of indemnities, costs and damages, is Dollars. Any amount received or
recovered in a currency other than Dollars (whether as a result of a judgment or
order of a court of any jurisdiction, or the enforcement thereof, in the winding
up or dissolution of the Guarantor or otherwise) by any Beneficiary in respect
of any sum expressed to be due to it from the Guarantor shall only constitute a
discharge to the Guarantor to the extent of the amount of Dollars that the
recipient is able to purchase with the amount so received or recovered in that
currency on the date of that receipt or recovery (or, if it is not practicable
to make that purchase on that date, on the first date on which it is practicable
to do so). If that amount of Dollars is less than the amount of Dollars
expressed to be due to the recipient under this Agreement, the Guarantor shall
indemnify it against any loss sustained by it as a result. In any event, the
Guarantor shall indemnify the recipient against the cost of making any such
purchase. For the purpose of this Guarantee, it will be sufficient for any
Beneficiary to demonstrate that it would have suffered a loss had an actual
purchase been made. These indemnities constitute a separate and independent
cause of action, shall apply irrespective of any indulgence granted by any
Beneficiary and shall continue in full force and effect despite any other
judgment, order, claim or proof for a liquidated amount in respect of any sum
due under this Agreement or the Credit Agreement or any other judgment or order.

            SECTION 5.0. SURVIVAL OF AGEEMENT. This Agreement and the terms,
covenants and conditions hereof shall be binding upon the Guarantor and its
successors

                                                                               8

successors and assigns. The Guarantor shall not be permitted to assign or
transfer any of its rights or obligations under this Agreement, except as
expressly contemplated by this Agreement or the Credit Agreement.

            SECTION 5.03. WAIVERS; AMENDMENT. (a) No failure on the part of any
Beneficiary to exercise, and no delay in exercising, any right, power or remedy
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or remedy by any Beneficiary preclude any
other or further exercise thereof or the exercise of any other right, power or
remedy. All remedies hereunder and under the Credit Agreement are cumulative and
are not exclusive of any other remedies provided by law. Except as provided in
the Credit Agreement, neither the Administrative Agent nor the Lenders shall be
deemed to have waived any rights hereunder or under any other agreement or
instrument unless such waiver shall be in writing and signed by such parties.

            (b) (i) Neither this Agreement nor any provision hereof may be
waived, amended or modified except pursuant to a written agreement entered into
between the Guarantor and the Administrative Agent with the prior written
consent of the Majority Lenders and (ii) this Agreement shall not be terminated
and the Guarantor shall not be released from any of its obligations under
Article II of this Agreement without the prior written consent of all of the
Lenders.

            SECTION 5.04. GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED IN

based upon this Agreement and the transactions contemplated hereby may be
