Revolving Borrowing, in the case of a Revolving Borrowing consisting of

12:00 P.M. (New York City time) on such date, in the case of a Revolving
Borrowing consisting of Eurodollar Rate Advances, or 4:00 P.M. (New York City

(i) the Borrower may not select Eurodollar Rate Advances for any Revolving
Borrowing if the aggregate amount of such Revolving Borrowing is less than
$5,000,000 or if the obligation of the Lenders to make Eurodollar Rate Advances
shall then be suspended pursuant to Section 2.09 or 2.13 and (ii) the Eurodollar
Rate Advances may not be outstanding as part of more than twelve separate
Revolving Borrowings.

         (c) Each Notice of Borrowing shall be irrevocable and binding on the
Borrower. In the case of any Revolving Borrowing that the related Notice of
Borrowing specifies is to be comprised of Eurodollar Rate Advances, the 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 date specified in
such Notice of Borrowing for such Revolving Borrowing the applicable conditions
set forth in Article III, including, without limitation, any loss, cost or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Lender to fund the Revolving Advance to be made by
such Lender as part of such Revolving Borrowing when such Revolving Advance, as

Lender prior to the date of any Revolving Borrowing that such Lender will not
make available to the Administrative Agent such Lender's ratable portion of such
Revolving Borrowing, the Administrative Agent may assume that such Lender has
made such portion available to the Administrative Agent on the date of such
Revolving Borrowing in accordance with subsection (a) of this Section 2.02 and
the Administrative Agent may, in reliance upon such assumption, make available
to the 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 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 the Borrower until the date such amount is repaid to the Administrative
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to Revolving Advances comprising such Revolving 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 Revolving Advance as part of such Revolving Borrowing
for purposes of this Agreement.

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

                  SECTION 2.03. The CAF Advances. (a) From time to time on any
Business Day during the period from the Effective Date until the Termination
Date, the Borrower may request CAF Advances from the Lenders in amounts such
that the Total Aggregate Outstanding Extensions of Credit at any time shall not
exceed the Total Commitments at such time (the "CAF Facility").

         (b) Under the terms and conditions set forth below, the Borrower may
borrow, repay pursuant to Section 2.07 and reborrow under this Section 2.03.

                  SECTION 2.04. Competitive Bid Procedure. (a) In order to
request a CAF Advance, the Borrower shall deliver to the Administrative Agent a
written notice in the form of Exhibit E, attached hereto (a "Competitive Bid
Request"), to be received by the Administrative Agent (i) in the case of each
CAF Eurodollar Rate Advance, not later than 3:00 P.M. (New York City time), four
(4) Business Days before the Borrowing Date specified for such CAF Eurodollar
Rate Advance and (ii) in the case of each Fixed Rate Advance, not later than
11:00 A.M. (New York City time), one (1) Business Day before the Borrowing Date
specified for such Fixed Rate Advance. Each Competitive Bid Request shall in
each case refer to this Agreement and specify (i) the date of Borrowing of such
CAF Advances (which shall be a Business Day), (ii) the aggregate principal
amount thereof, (iii) whether the CAF Advances then being requested are to be
CAF Eurodollar Rate Advances or Fixed Rate Advances, (iv) the maturity date for
each CAF Advance requested to be made and (v) the interest payment dates for
each CAF Advance requested to be made. The Administrative Agent shall promptly
notify each Lender by telex or facsimile transmission of the contents of each
Competitive Bid Request received by it. Each Competitive Bid Request may solicit
bids for CAF Advances in an aggregate principal amount of $5,000,000 or an
integral multiple of $1,000,000 in excess thereof and for not more than three
alternative maturity dates for such CAF Advances. The maturity date for each CAF
Advance shall be not less than 15 days nor more than 180 days after the
applicable date of CAF Borrowing (and in any event shall not extend beyond the
Termination Date).

         (b) Each Lender may, in its sole discretion, irrevocably offer to make
one or more CAF Advances to the Borrower responsive to each Competitive Bid
Request from the Borrower. Any such irrevocable offer by a Lender must be
received by the Administrative Agent, in the form of Exhibit F hereto (a
"Competitive Bid"), (i) in the case of each CAF Eurodollar Rate Advance, not
later than 10:30 A.M. (New York City time), three (3) Business Days before the
Borrowing Date specified for such CAF Eurodollar Rate Advance and (ii) in the
case of each Fixed Rate Advance, not later than 9:30 A.M. (New York City time)
on the Borrowing Date specified for such Fixed Rate Advance. Competitive Bids
that do not conform substantially to the format of Exhibit F may be rejected by
the Administrative Agent after conferring with, and upon the instruction of, the
Borrower, and the Administrative Agent shall notify the Lender of such rejection
as soon as practicable. Each Competitive Bid shall refer to this Agreement and
(i) specify the maximum principal amount of CAF Advances for each maturity date
(which shall be in an aggregate principal amount not less than $5,000,000 or an
integral multiple of $1,000,000 in excess thereof and which may equal, but not
exceed, the principal amount requested for such maturity date by the Borrower)
and the

                   CERC 364-Day Revolving Credit Agreement



                                       19

aggregate maximum principal amount of CAF Advances for all maturity dates (which
amount, with respect to any Lender, may exceed such Lender's Commitment) that
the Lender is willing to make to the Borrower, and (ii) specify the CAF Rate at
which the Lender is prepared to make each such CAF Advance. A Competitive Bid
submitted by a Lender pursuant to this Section 2.04(b) shall be irrevocable
absent manifest error.

         (c) The Administrative Agent shall (i) in the case of each CAF
Eurodollar Rate Advance, not later than 11:00 A.M. (New York City time) three
(3) Business Days before the Borrowing Date specified for such CAF Eurodollar
Rate Advance and (ii) in the case of each Fixed Rate Advance, not later than
10:00 A.M. (New York City time) on the Borrowing Date specified for such Fixed
Rate Advance, notify the Borrower in writing of all the Competitive Bids made
(arranging each such bid in ascending interest rate order), and the CAF Rate or
Rates and the maximum principal amount of each CAF Advance in respect of which a
Competitive Bid was made, and the identity of the Lender that made each bid. The
Administrative Agent shall send a copy of all Competitive Bids to the Borrower
for its records as soon as practicable after completion of the bidding process
set forth in this Section 2.04.

         (d) The Borrower may in its sole and absolute discretion, subject only
to the provisions of this Section 2.04(d), accept or reject any Competitive Bid
referred to in Section 2.04(c); provided, however, that the aggregate amount of
the Competitive Bids for CAF Advances so accepted by the Borrower may not exceed
the lesser of (i) the principal amount of the applicable CAF Borrowing requested
by the Borrower in respect thereof and (ii) the amount of the Commitments less
the Total Aggregate Outstanding Extensions of Credit then outstanding, after
giving effect to the application of the proceeds of such respective CAF
Borrowing on the Borrowing Date therefor. The Borrower shall notify the
Administrative Agent in writing whether and to what extent it has decided to
accept or reject any or all of the bids referred to in Section 2.04(c) by
delivering to the Administrative Agent a written notice in the form of Exhibit G
hereto (a "Competitive Bid Confirmation"), (i) in the case of each CAF
Eurodollar Rate Advance, not later than 1:00 P.M. (New York City time), three
(3) Business Days before the Borrowing Date specified for such CAF Eurodollar
Rate Advance and (ii) in the case of each Fixed Rate Advance, not later than
11:00 A.M. (New York City time) on the Borrowing Date specified for such Fixed
Rate Advance, which Competitive Bid Confirmation shall specify the principal
amount of CAF Advances for each relevant maturity date to be made by each such
bidding Lender (which amount for each such maturity date shall be equal to or
less than the maximum amount for such maturity date specified in the Competitive
Bid of such Lender, and for all maturity dates included in such Competitive Bid
in respect thereof shall be equal to or less than the aggregate maximum amount
specified in such Competitive Bid for all such maturity dates); provided,
however, that (A) the failure by the Borrower to so deliver a Competitive Bid
Confirmation by the specified time shall be deemed to be a rejection of all the
bids referred to in Section 2.04(c) for the related Competitive Bid Request; (B)
the Borrower shall not accept a bid made at a particular CAF Rate for a
particular maturity if the Borrower has decided to reject a bid made at a lower
CAF Rate for such maturity; (C) if the Borrower shall accept bids made at a
particular CAF Rate for a particular maturity but shall be restricted by other
conditions hereof from borrowing the maximum principal amount of CAF Advances in
respect of which bids at such CAF Rate have been made, then the Borrower shall
accept a pro rata portion of each bid made at such CAF Rate based as nearly as
possible on the respective maximum principal amounts of CAF Advances offered to
be made by the relevant Lenders pursuant to such bids; and (D) no bid shall be
accepted for a CAF Advance by any Lender unless such CAF Advance is in an
aggregate principal amount not less than $5,000,000 or an integral multiple of
$1,000,000 in excess thereof. Notwithstanding the foregoing, if it is necessary
for the Borrower to accept a pro rata allocation of the bids made in response to
a Competitive Bid Request (whether pursuant to the events specified in clause
(C) above or otherwise) and the available principal amount of CAF Advances to be
allocated among the Lenders is not sufficient to enable CAF Advances to be
allocated to each Lender in an aggregate principal amount not less than
$5,000,000 or in integral multiples of $1,000,000 in excess thereof, then the
Borrower shall, subject to clause (D) above, select the Lenders to be allocated
such CAF Advances and shall round allocations up or down to the next higher or
lower multiple of $1,000,000 as it shall deem appropriate; provided that the
allocations among the Lenders to be allocated such CAF Advances shall be made
pro rata based as nearly as possible on the respective maximum principal amounts
of CAF Advances offered to be made by such Lenders. The Competitive Bid
Confirmation given by the Borrower pursuant to this Section 2.04(d) shall be
irrevocable.

         (e) Upon receipt from the Administrative Agent of the Eurodollar Rate
applicable to any CAF Eurodollar Rate Advance to be made by any Lender pursuant
to a Competitive Bid that has been accepted by the Borrower pursuant to this
Section 2.04, the Administrative Agent shall notify such Lender of the
applicable Eurodollar Rate.

                                       20

         (f) If the Administrative Agent shall at any time elect to submit a
Competitive Bid in its capacity as a Lender, it shall submit such bid directly
to the Borrower by (i) in the case of a CAF Eurodollar Rate Advance, not later
than 10:15 A.M. (New York City time), and (ii) in the case of a Fixed Rate
Advance, not later than 9:15 A.M. (New York City time), in each case, on the
Business Day on which the other Lenders are required to submit their bids to the
Administrative Agent pursuant to Section 2.04(b) above.

         (g) If the Borrower accepts pursuant to Section 2.04(d) one or more of
the offers made by any Lender or Lenders, the Administrative Agent shall
promptly notify each Lender that has made such an offer of the aggregate amount
of such CAF Advances to be made on the Borrowing Date for each maturity date and
of the acceptance or rejection of any offers to make such CAF Advances made by
such Lender. Each Lender that is to make a CAF Advance shall, before 12:00 Noon
(New York City time) on the Borrowing Date specified in the Competitive Bid
Request applicable thereto, make available to the Administrative Agent at its
office set forth in Section 8.02 the amount of CAF Advances to be made by such
Lender, in immediately available funds. The Administrative Agent shall, no later
than 1:00 P.M. (New York City time) on such Borrowing Date, make such funds
available to the Borrower at the Borrower's account as shall be designated by it
to the Administrative Agent from time to time. As soon as practicable after each
Borrowing Date, the Administrative Agent shall notify each Lender of the
aggregate amount of CAF Advances advanced on such Borrowing Date and the
respective maturity dates thereof.

         (h) The Borrower shall repay to the Administrative Agent for the
account of each Lender that has made a CAF Advance (or the Eligible Assignee in
respect thereof, as the case may be) on the maturity date of each CAF Advance
(such maturity date being that specified by the Borrower for repayment of such
CAF Advance in the related Competitive Bid Request) the then unpaid principal
amount of such CAF Advance. The Borrower shall not, without the consent of the
relevant Lender, have the right to prepay, at its option, any principal amount
of any CAF Advance.

All notices required by this Section 2.04 shall be made in accordance with
Section 8.02 hereof; provided, however, that each request or notice required to
be made under Section 2.04(a) or 2.04(d) by the Borrower may be made by the
giving of telephone notice to the Administrative Agent that is promptly
confirmed by delivery of a notice in writing (in substantially the form of
Exhibit B or Exhibit E, as the case may be) to the Administrative Agent.

                  SECTION 2.05. Fees. (a) Facility Fee. The Borrower agrees to
pay to the Administrative Agent for the account of each Lender a facility fee on
the aggregate amount of such Lender's Commitment, irrespective of usage, from
the Effective Date in the case of each Initial Lender 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 until the Termination Date at a rate per
annum equal to the Applicable Percentage in effect from time to time, payable in
arrears quarterly on the last day of each March, June, September and December,
commencing June 30, 2003, and on the Termination Date.

         (b) Agents' Fees. The Borrower shall pay to each Agent for its own
account such fees as may from time to time be agreed between the Borrower and
such Agent.

                  SECTION 2.06. Termination or Reduction of the Commitments. The
Borrower shall have the right, upon at least three Business Days' notice to the
Administrative Agent, to terminate in whole or permanently reduce ratably in
part the unused portions of the respective Commitments of the Lenders, provided
that (i) each partial reduction shall be in a minimum aggregate amount of
$10,000,000 or an integral multiple of $1,000,000 in excess thereof and (ii) no
such termination or reduction shall be permitted if, after giving effect thereto
and to any prepayments made under Section 2.11 by the Borrower on the effective
date thereof, the Total Aggregate Outstanding Extensions of Credit then
outstanding would exceed the Total Commitments then in effect. Any terminated or
permanently reduced portion of the respective Commitments of the Lenders may not
be reinstated.

                  Each reduction of Commitments pursuant to this Section 2.06
shall be applied pro rata to the Commitments of each Lender. If at any time,
including after giving effect to any reduction of Commitments pursuant to this
Section 2.06, the Total Aggregate Outstanding Extensions of Credit exceed the
Total Commitments, the Borrower shall be obligated, first, to prepay the
Revolving Advances in the amount of such excess and second, to prepay the CAF
Advances (whether or not consented to by the relevant Lender) to the extent that
the aggregate amount of CAF Advances exceeds such Total Commitments after
prepayment of all Revolving Advances.

                                       21

                  SECTION 2.07. Repayment. The Borrower shall repay to the
Administrative Agent for the ratable account of the Lenders on the Termination
Date the aggregate principal amount of the Revolving Advances then outstanding.

                  SECTION 2.08. Interest. (a) Scheduled Interest. The Borrower
shall pay interest on the unpaid principal amount of each Revolving Advance
owing to each Lender from the date of such Revolving Advance to but excluding
the date such principal amount shall be paid in full, at the following rates per
annum:

                  (i) Base Rate Advances. During such periods as such Revolving
         Advance is a Base Rate Advance, a rate per annum equal at all times to
         the sum of (x) the Base Rate in effect from time to time plus (y) the
         Applicable Margin in effect from time to time, payable in arrears
         quarterly on the last day of each March, June, September and December,
         during such periods and on the date such Base Rate Advance shall be
         Converted or paid in full.

                  (ii) Eurodollar Rate Advances. During such periods as such
         Advance is a Revolving Advance bearing interest at the Eurodollar Rate,
         a rate per annum equal at all times during each Interest Period for
         such Revolving Advance to the sum of (x) the Eurodollar Rate for such
         Interest Period for such Revolving Advance plus (y) the Applicable
         Margin in effect from time to time, payable in arrears on the last day
         of such Interest Period and, if such Interest Period has a duration of
         more than three months, on each day that occurs during such Interest
         Period every three months from the first day of such Interest Period
         and on the date such Eurodollar Rate Advance shall be Converted or paid
         in full.

                  (iii) CAF Eurodollar Rate Advances. In the case of each CAF
         Eurodollar Rate Advance, a rate per annum equal at all times to the sum
         of the Eurodollar Rate applicable to such CAF Advance plus or minus, as
         the case may be, the CAF Margin specified by a Lender with respect to
         such CAF Advance in its Competitive Bid submitted pursuant to Section
         2.04(b), payable on the date or dates specified in the relevant
         Competitive Bid Request.

         (b) Default Interest. Upon the occurrence and during the continuance of
any default in the payment of any amount owed hereunder, the Administrative
Agent may, and upon the request of the Required Lenders shall, require the
Borrower to pay interest ("Default Interest") on (i) the unpaid principal amount
of each Revolving Advance past due and owing to each Lender, payable in arrears
on the dates referred to in clause (a)(i) or (a)(ii) above, at a rate per annum
equal at all times to 2.00% per annum above the rate per annum required to be
paid on such Revolving Advance pursuant to clause (a)(i), (a)(ii) or (a)(iii)
above and (ii) to the fullest extent permitted by law, the amount of any
interest, fee or other amount payable hereunder that is not paid when due, from
the date such amount shall be due until such amount shall be paid in full,
payable in arrears on the date such amount shall be paid in full and on demand,
at a rate per annum equal at all times to 2.00% per annum above the rate per
annum required to be paid on Base Rate Advances pursuant to clause (a)(i) above;
provided, however, that following acceleration of the Advances pursuant to
Section 6.01, Default Interest shall accrue and be payable hereunder whether or
not previously required by the Administrative Agent.

                  SECTION 2.09. Interest Rate Determination. (a) The
Administrative Agent shall give prompt notice to the Borrower and the Lenders of
the applicable interest rate determined by the Administrative Agent for purposes
of Section 2.08(a)(i), (ii) or (iii).

         (b) If, with respect to any Eurodollar Rate Advances, the Required
Lenders notify the Administrative Agent that the Eurodollar Rate for any
Interest Period for such Revolving Advances will not adequately reflect the cost
to such Required Lenders of making, funding or maintaining their respective
Eurodollar Rate Advances for such Interest Period, the Administrative Agent
shall forthwith so notify the Borrower and the Lenders, whereupon (i) each
Eurodollar Rate Advance will automatically, on the last day of the then existing
Interest Period therefor, Convert into a Base Rate Advance, and (ii) the
obligation of the Lenders to make, or to Convert Revolving Advances into,
Eurodollar Rate Advances shall be suspended until the Administrative Agent shall
notify the Borrower and the Lenders that the circumstances causing such
suspension no longer exist.

         (c) If the Borrower shall fail to select the duration of any Interest
Period for any Eurodollar Rate Advances in accordance with the provisions
contained in the definition of "Interest Period" in Section 1.01, the
Administrative

                   CERC 364-Day Revolving Credit Agreement



                                       22

Agent will forthwith so notify the Borrower and the Lenders and such Revolving
Advances will automatically, on the last day of the then existing Interest
Period therefor, Convert into Base Rate Advances. If no Advances are outstanding
at the time of delivery of a Notice of Borrowing with respect to Eurodollar Rate
Advances and the Borrower shall fail to select an Interest Period for such
Advances, such Advances shall be made as Base Rate Advances.

         (d) On the date on which the aggregate unpaid principal amount of
Eurodollar Rate Advances comprising any Revolving Borrowing shall be reduced, by
payment or prepayment or otherwise, to less than $5,000,000, such Revolving
Advances shall automatically Convert into Base Rate Advances.

         (e) Upon the occurrence and during the continuance of any Event of
Default under Section 6.01(a), (i) each Eurodollar Rate Advance will
automatically, on the last day of the then existing Interest Period therefor,
Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make,
or to Convert Revolving Advances into, Eurodollar Rate Advances shall be
suspended.

                  SECTION 2.10. Optional Conversion of Revolving Advances. The
Borrower may on any Business Day, upon notice given to the Administrative Agent
not later than 11:00 A.M. (New York City time) on the third Business Day prior
to the date of the proposed Conversion and subject to the provisions of Sections
2.09 and 2.13, Convert all Revolving Advances of one Type comprising the same
Borrowing into Revolving Advances of the other Type; provided, however, that any
Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made
only on the last day of an Interest Period for such Eurodollar Rate Advances,
any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in
an amount not less than the minimum amount specified in Section 2.02(b) and no
Conversion of any Revolving Advances shall result in more separate Borrowings
than permitted under Section 2.02(b). Each such notice of a Conversion shall,
within the restrictions specified above, specify (i) the date of such
Conversion, (ii) the Revolving Advances to be Converted, and (iii) if such
Conversion is into Eurodollar Rate Advances, the duration of the initial
Interest Period for each such Revolving Advance. Each notice of Conversion shall
be irrevocable and binding on the Borrower.

                  SECTION 2.11. Prepayments of Revolving Advances. (a) Optional
Prepayments. The Borrower may, upon at least two Business Days' notice to the
Administrative Agent, in the case of a Revolving Borrowing consisting of
Eurodollar Rate Advances, or upon same day notice to the Administrative Agent,
in the case of a Revolving Borrowing consisting of Base Rate Advances, stating
the proposed date and aggregate principal amount of the prepayment, and if such
notice is given the Borrower shall, prepay the outstanding principal amount of
the Revolving Advances comprising part of the same Revolving 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 a minimum aggregate principal amount of
$10,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in
the event of any such prepayment of a Eurodollar Rate Advance, the Borrower
shall be obligated to reimburse the Lenders in respect thereof pursuant to
Section 8.04(c).

                  (b) Mandatory Prepayments from Excess Cash Flow. The Borrower
shall, on the day the Borrower files its Form 10-Q or Form 10-K, but not later
than 45 days following the end of each calendar quarter (the "Prepayment Date"
and the "Reference Quarter", respectively), prepay an aggregate principal amount
of the Revolving Advances comprising part of the same Revolving Borrowings in an
amount sufficient to cause the aggregate principal amount of all Advances
outstanding as of the Prepayment Date to equal the aggregate principal amount of
all Advances outstanding as of the first day of the Reference Quarter, less the
amount of Excess Cash Flow for the Reference Quarter. Amounts prepaid under this
Section 2.11(b) shall be available to be reborrowed on the following Business
Day, provided that all other conditions to such Borrowing under this Agreement
are met.

                  SECTION 2.12. Increased Costs. (a) If, after the date hereof,
due to either (i) the introduction of or any change 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 be any increase in the cost to any Lender of agreeing
to make or making, funding or maintaining Eurodollar Rate Advances or CAF
Eurodollar Rate Advances (excluding for purposes of this Section 2.12 any such
increased costs resulting from (A) Taxes or Other Taxes (as to which Section
2.15 shall govern), (B) net income taxes and franchise taxes imposed on such
Lender as a result of a present or former connection between the jurisdiction of
the government or taxing authority imposing such tax and such Lender other than
a connection arising solely from such Lender having

                   CERC 364-Day Revolving Credit Agreement



                                       23

executed, delivered or performed its obligations or received a payment under, or
enforced, this Agreement or the Advances and (C) changes in the rate of tax on
the overall net income of such Lender), then the Borrower shall from time to
time, upon demand by such Lender (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such
Lender additional amounts sufficient to compensate such Lender for such actual
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 Borrower and the
Administrative Agent by such Lender, shall be conclusive and binding for all
purposes, absent manifest error.

         (b) If any Lender determines in good faith that compliance with any law
or regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and that the amount of such
capital is increased by or based upon the existence of such Lender's commitment
to lend hereunder and other commitments of this type, then, upon demand by such
Lender (with a copy of such demand to the Administrative Agent), the Borrower
shall pay to the Administrative Agent for the account of such Lender, from time
to time as specified by such Lender, additional amounts sufficient to compensate
such Lender or such corporation in the light of such circumstances, to the
extent that such Lender reasonably determines such increase in capital to be
allocable to the existence of such Lender's commitment to lend hereunder. A
certificate as to such amounts submitted to the Borrower and the Administrative
Agent by such Lender shall be conclusive and binding for all purposes, absent
manifest error.

         (c) The agreements contained in this Section 2.12 shall survive the
termination of this Agreement and the payment of all amounts payable hereunder;
provided, however, that in no event shall the Borrower be obligated to reimburse
or compensate any Lender for amounts contemplated by this Section 2.12 for any
period prior to the date that is 90 days prior to the date upon which such
Lender requests in writing such reimbursement or compensation from the Borrower.

                  SECTION 2.13. Illegality. Notwithstanding any other provision
of this Agreement, if any Lender shall notify the Administrative Agent that it
has determined in good faith 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 any Lender or
its Eurodollar Lending Office to perform its obligations hereunder to make
Eurodollar Rate Advances or CAF Eurodollar Rate Advances or to fund or maintain
Eurodollar Rate Advances or CAF Eurodollar Rate Advances hereunder, (a) each
Eurodollar Rate Advance or CAF Eurodollar Rate Advance, as the case may be, will
automatically, upon such demand, Convert into a Base Rate Advance or an Advance
that bears interest at the rate set forth in Section 2.08(a)(i), as the case may
be, and (b) the obligation of the Lenders to make Eurodollar Rate Advances or
CAF Eurodollar Rate Advances or to Convert Revolving Advances into, Eurodollar
Rate Advances shall be suspended until the Administrative Agent shall notify the
Borrower and the Lenders that the circumstances causing such suspension no
longer exist; 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 Eurodollar Lending Office
if the making of such a designation would allow such Lender or its Eurodollar
Lending Office to continue to perform its obligations to make Eurodollar Rate
Advances or CAF Eurodollar Rate Advances, as the case may be, or to continue to
fund or maintain Eurodollar Rate Advances or CAF Eurodollar Rate Advances, as
the case may be, and would not, in the judgment of such Lender, be otherwise
disadvantageous to such Lender.

                  SECTION 2.14. Payments and Computations. (a) The Borrower
shall make each payment hereunder and under the Notes (if any), irrespective of
any right of counterclaim or set-off, not later than 12:00 Noon (New York City
time) on the day when due in U.S. dollars to the Administrative Agent at the
Administrative Agent's Account in same day funds. The Administrative Agent will
promptly thereafter cause to be distributed like funds relating to the payment
of principal or interest or facility fees ratably (other than amounts payable
pursuant to Sections 2.04, 2.12, 2.15 or 8.04(c)) to the Lenders for the account
of their respective Applicable Lending Offices, and like funds relating to the
payment of any other amount payable to any Lender to such Lender for the account
of its Applicable Lending Office, in each case to be applied in accordance with
the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance
and recording of the information

                   CERC 364-Day Revolving Credit Agreement



                                       24

contained therein in the Register pursuant to Section 8.07(c), from and after
the effective date specified in such Assignment and Acceptance, the
Administrative Agent shall make all payments hereunder and under the Notes or
CAF Notes (if any) 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) The Borrower hereby authorizes each Lender, if and to the extent
payment owed to such Lender is not made when due hereunder or under the Note or
CAF Note, as the case may be, held by such Lender (if any), to charge from time
to time against any or all of the Borrower's accounts with such Lender any
amount so due.

         (c) All computations of interest based on the Base Rate shall be made
by the Administrative Agent on the basis of a year of 365 or 366 days, as the
case may be, and all computations of interest based on the Eurodollar Rate, the
CAF Rate or the Federal Funds Rate or in respect of Fixed Rate Advances and of
facility fees shall be made by the Administrative Agent 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
facility fees are payable. Each determination by the Administrative Agent of an
interest rate hereunder shall be prima facie evidence of the correctness
thereof.

         (d) Whenever any payment hereunder or under the Notes or CAF Notes (if
any) 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
facility fee, as the case may be; provided, however, that, if such extension
would cause payment of interest on or principal of Eurodollar Rate Advances or
CAF Eurodollar Rate Advances to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

         (e) Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Lenders hereunder
that the Borrower will not make such payment in full, the Administrative Agent
may assume that the 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 the 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 2.15. Taxes. (a) Any and all payments by the Borrower
to or for the account of any Lender or the Administrative Agent hereunder or
under the Notes or CAF Notes (if any) or any other documents to be delivered
hereunder shall be made, in accordance with Section 2.14 or the applicable
provisions of such other documents, 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, net income taxes and franchise
taxes imposed on it as a result of a present or former connection between the
jurisdiction of the government or taxing authority imposing such tax and the
Administrative Agent or such Lender other than a connection arising solely from
the Administrative Agent or such Lender having executed, delivered or performed
its obligations or received a payment under, or enforced, this Agreement or any
Note or CAF Note, if any (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities in respect of payments
hereunder or under the Notes or CAF Notes (if any) being hereinafter referred to
as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder or under any Note or CAF Note or any
other documents to be delivered 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 2.15) 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) the Borrower shall make such deductions
and (iii) the Borrower shall pay the full amount deducted to the relevant
taxation authority or other authority in accordance with applicable law;
provided, however, that the Borrower shall not be required to increase any such
sums payable to any Lender with respect to any Taxes (i) that are attributable
to such Lender's failure to comply with the requirements of Section 2.15(e) or
(ii) that are United States withholding taxes imposed on sums payable to such
Lender at the time such Lender becomes a party

                   CERC 364-Day Revolving Credit Agreement



                                       25

to this Agreement, except to the extent that any such Lender's assignor (if any)
was entitled, at the time of assignment, to receive additional amounts from the
Borrower with respect to such Taxes pursuant to this Section 2.15. Whenever any
Taxes or Other Taxes (as defined in Section 2.15(b)) are payable by the
Borrower, as promptly as possible thereafter the Borrower shall send to the
Administrative Agent for the account of the relevant Lender or Administrative
Agent, as the case may be, either (A) official tax receipts or notarized copies
of such receipts to such Lender within thirty (30) days after payment of any
applicable tax or (B) a certificate executed by a Responsible Officer of the
Borrower confirming that such Taxes or Other Taxes have been paid, together with
evidence of such payment.

         (b) In addition, the Borrower shall pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or under the Notes or CAF
Notes (if any) or any other documents to be delivered hereunder or from the
execution, delivery or registration of, performing under, or otherwise with
respect to, this Agreement or the Notes or CAF Notes (if any) or any other
documents to be delivered hereunder (hereinafter referred to as "Other Taxes").

         (c) The Borrower shall indemnify each Lender and the Administrative
Agent for and hold it harmless against the full amount of Taxes or Other Taxes
(including, without limitation, taxes of any kind imposed or asserted by any
jurisdiction on amounts payable under this Section 2.15) imposed on or paid by
such Lender or the Administrative Agent (as the case may be) and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto.

         (d) Within 30 days after the date of any payment of Taxes, the Borrower
shall furnish to the Administrative Agent, at its address referred to in Section
8.02, the original or a certified copy of a receipt evidencing such payment to
the extent such a receipt is issued therefor, or other written proof of payment
thereof that is reasonably satisfactory to the Administrative Agent. In the case
of any payment hereunder or under the Notes or CAF Notes (if any) or any other
documents to be delivered hereunder by or on behalf of the Borrower through an
account or branch outside the United States or by or on behalf of the Borrower
by a payor that is not a United States person, if the Borrower determines that
no Taxes are payable in respect thereof, the Borrower shall furnish, or shall
cause such payor to furnish, to the Administrative Agent, at such address, an
opinion of counsel acceptable to the Administrative Agent stating that such
payment is exempt from 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.

         (e) Each Lender registered in the Register that is not a United States
person as defined in Section 7701(a)(30) of the Internal Revenue Code agrees
that it will deliver to the Borrower and the Administrative Agent on the
Effective Date, or on the date which it becomes a party to this Agreement, two
duly completed copies of United States Internal Revenue Service Form W-8BEN,
W-8ECI, W-8EXP or W-8IMY (or other appropriate corresponding form) or any
successor applicable form, as the case may be. Each such Lender also agrees to
deliver to the Borrower and the Administrative Agent two further copies of the
said Form W-8BEN, W-8ECI, W-8EXP or W-8IMY or successor applicable forms or
other manner of certification, as the case may be, on or before the date that
any such form expires or becomes obsolete or after the occurrence of any event
requiring a change in the most recent form previously delivered by it to the
Borrower, and such extensions or renewals thereof as may reasonably be requested
by the Borrower or the Administrative Agent, unless in any such case an event
(including, without limitation, any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required that renders all such forms inapplicable or that would prevent such
Lender from duly completing and delivering any such form with respect to it and
such Lender so advises the Borrower and the Administrative Agent. Each such
Lender shall certify in the case of a Form W-8BEN, W-8ECI, W-8EXP or W-8IMY that
is entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes. In the event that any
such Lender fails to deliver any forms required under this Section 2.15(e), the
Borrower's obligation to pay additional amounts shall be reduced to the amount
that it would have been obligated to pay had such forms been provided.

         (f) For any period with respect to which a Lender has failed to provide
the Borrower with the appropriate form, certificate or other document described
in Section 2.15(e) (other than if such failure is due to a change in law, or in
the interpretation or application thereof, occurring subsequent to the date on
which a form, certificate or other document originally was required to be
provided, or if such form, certificate or other document otherwise is not

                   CERC 364-Day Revolving Credit Agreement



                                       26

required under subsection (e) above), such Lender shall not be entitled to
indemnification under Section 2.15(a) or (c) with respect to Taxes imposed by
the United States by reason of such failure; provided, however, that should a
Lender become subject to Taxes because of its failure to deliver a form,
certificate or other document required hereunder, the Borrower shall take such
steps as the Lender shall reasonably request to assist the Lender to recover
such Taxes.

         (g) Any Lender claiming any additional amounts payable pursuant to this
Section 2.15 agrees to use reasonable efforts (consistent with its internal
policy and legal and regulatory restrictions) to change the jurisdiction of its
Applicable 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.

         (h) If any Taxes or Other Taxes are not correctly or legally asserted
and the Agent or any Lender determines, in its sole discretion, that it has
received a refund of those Taxes or Other Taxes as to which it has been
indemnified by the Borrower, the Administrative Agent or such Lender shall
within 20 days after such refund pay to the Borrower the amount of such refund
to the extent that the Borrower indemnified the Administrative Agent or such
Lender for such Taxes or Other Taxes pursuant to this Section 2.15, net of any
out-of-pocket costs of the Administrative Agent or such Lender and without
interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund); provided, that the Borrower, upon the request of
the Administrative Agent or such Lender, agrees to repay the amount paid over to
the Borrower (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Administrative Agent or such Lender in
the event the Administrative Agent or such Lender is required to repay such
refund to such Governmental Authority. This paragraph shall not be construed to
require the Administrative Agent or any Lender to make available its tax returns
(or any other information relating to its taxes which it deems confidential) to
the Borrower or any other Person.

                  SECTION 2.16. 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 Advances owing to it
(other than pursuant to Sections 2.12, 2.15 or 8.04(c)) in excess of its ratable
share of payments on account of the Revolving Advances obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in the Revolving Advances owing to 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 Borrower
agrees that any Lender so purchasing a participation from another Lender
pursuant to this Section 2.16 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 the
Borrower in the amount of such participation.

                  SECTION 2.17. Use of Proceeds. The proceeds of the Advances
shall be available (and the Borrower agrees that it shall use such proceeds)
solely for working capital, including capital expenditures, and to repay
commercial paper.

                  SECTION 2.18. Evidence of Debt. (a) Each Lender shall maintain
in accordance with its usual practice an account or accounts evidencing the
indebtedness of the Borrower to such Lender resulting from each Advance owing to
such Lender from time to time, including the amounts of principal and interest
payable and paid to such Lender from time to time hereunder. The Borrower agrees
that upon notice by any Lender to the Borrower (with a copy of such notice to
the Administrative Agent) to the effect that a promissory note or other evidence
of indebtedness is required or appropriate in order for such Lender to evidence
(whether for purposes of pledge, enforcement or otherwise) the Advances owing
to, or to be made by, such Lender, the Borrower shall promptly execute and
deliver to such Lender, with a copy to the Administrative Agent, a Note or a CAF
Note, as the case may be, in substantially the form of Exhibit A or Exhibit D
hereto, respectively and as the case may be, payable to the order of such Lender
in a principal amount equal to the amount of the Revolving Advance or the CAF
Advance, as

                   CERC 364-Day Revolving Credit Agreement



                                       27

the case may be, of such Lender. All references to Notes or CAF Notes in the
Loan Documents shall mean Notes or CAF Notes, respectively and if any, to the
extent issued hereunder.

                  (b) The Register maintained by the Administrative Agent
pursuant to Section 8.07(c) shall include a control account, and a subsidiary
account for each Lender, in which accounts (taken together) shall be recorded
(i) the date and amount of each Borrowing made hereunder, the Type of Advances
comprising such Borrowing and, if appropriate, the Interest Period applicable
thereto, (ii) the terms of each Assignment and Acceptance delivered to and
accepted by it, (iii) the amount of any principal or interest due and payable or
to become due and payable from the Borrower to each Lender hereunder, and (iv)
the amount of any sum received by the Administrative Agent from the Borrower
hereunder and each Lender's share thereof.

                  (c) Entries made in good faith by the Administrative Agent in
the Register pursuant to subsection (b) above, and by each Lender in its account
or accounts pursuant to subsection (a) above, shall be prima facie evidence of
the amount of principal and interest due and payable or to become due and
payable from the Borrower to, in the case of the Register, each Lender and, in
the case of such account or accounts, such Lender, under this Agreement, absent
manifest error; provided, however, that the failure of the Administrative Agent
or such Lender Party to make an entry, or any finding that an entry is
incorrect, in the Register or such account or accounts shall not limit or
otherwise affect the obligations of the Borrower under this Agreement.

                                   ARTICLE III

                     CONDITIONS TO EFFECTIVENESS AND LENDING

         Credit Agreement, dated as of March 31, 1998 (as amended, supplemented
         or otherwise modified from time to time, the "Original Revolving Credit
         Facility"), among the Borrower, the lenders party thereto and Citibank,
         N.A. as Administrative Agent, shall be paid by the Borrower in full,
         and such Original Revolving Credit Facility shall be cancelled or
         otherwise terminated prior to or immediately after the initial Advances
         are made hereunder.

                  (c) Nothing shall have come to the attention of the Lenders
         during the course of their due diligence investigation to lead them to

         incorrect or incomplete in any material respect.

                  (d) The Borrower shall have paid all accrued fees and expenses

Notice of Borrowing signed by a Financial Officer of the Borrower, each of the
statements in which shall be true in all material respects.

                  SECTION 3.03. Conditions Precedent to Each CAF Borrowing. The

which the information concerning the Borrower that has been provided to the
Agent and each Lender by the Borrower in connection herewith would include an
untrue statement of a material fact or omit to state any material fact or any
fact necessary to make the statements contained therein, in the light of the
circumstances under which they were made, not misleading.

of determining compliance with the conditions specified in Section 3.01, each
Lender shall be deemed to have consented to, approved or accepted or to be

that the Borrower, by notice to the Lenders, designates as the proposed
Effective Date, specifying its objection thereto. The Administrative Agent shall
promptly notify the Lenders of the occurrence of the Effective Date.

         existing and in good standing under the laws of the State of Delaware.

                  (b) The execution, delivery and performance by the Borrower of

         consummation of the transactions contemplated hereby, are within the
         Borrower's corporate powers, have been duly authorized by all necessary

         of incorporation or by-laws or any law or any contractual restriction
         binding on or affecting the Borrower, or (ii) constitute a default
         under any existing indenture, loan agreement or other material
         agreement to which the Borrower or any Subsidiary of the Borrower is a

         notice to or filing with, any governmental authority or regulatory body

         Notes (if any), and no law or regulation is applicable that restrains,

                  (h) Neither the Borrower nor any Subsidiary of the Borrower is
         an "investment company" as defined in, or otherwise subject to
         regulation under, the Investment Company Act of 1940, as amended. None
         of the execution and delivery of the Loan Documents by the Borrower or
         the performance of its obligations thereunder violate any regulation
         under the Public Utility Holding Company Act of 1935, as amended.

                  (i) The Borrower is and each of its Subsidiaries are in

         regulations, and requirements of governmental authorities (including,
         without limitation, Environmental Laws and ERISA and the rules and
         regulations thereunder) except for any non-compliance that could not
         reasonably be expected to have a Material Adverse Effect.

                  (j) All written information heretofore furnished by the
         Borrower to the Administrative Agent or any Lender for purposes of or
         in connection with this Agreement or any transaction contemplated
         hereby or thereby is, and all such information hereafter furnished by
         the Borrower to the Administrative Agent or any Lender will be, true
         and accurate in all material respects on the date as of which such
         information is stated in the light of the circumstances under which
         such information was provided (as modified or supplemented by other
         information so furnished, when taken together as a whole as of the date
         so stated); provided, that, with respect to projected financial
         information, the Borrower represents only that such information was
         prepared in good faith based on assumptions believed to be reasonable
         at the time, it being recognized by the Lenders that such projections
         as to future events are not to be viewed as facts and that actual
         results during the period or periods covered by any such projections
         may differ from the projected results. The Borrower has disclosed to
         the Administrative Agent any and all facts specific to the Borrower and
         its Subsidiaries and known as of the date hereof to a Responsible
         Officer of the Borrower that could reasonably be expected to result in
         a Material Adverse Effect or which could reasonably be expected to
         materially and adversely affect or may affect (to the extent the
         Borrower can now reasonably foresee), the business, operations or
         financial condition of the Borrower and its Subsidiaries, taken as a
         whole.

                  (k) The Borrower is, and together with its Subsidiaries, taken
         as a whole, Solvent as of the date hereof.

                            COVENANTS OF THE BORROWER

                  SECTION 5.01. Affirmative Covenants. So long as any Advance
shall remain unpaid or any Lender shall have any Commitment hereunder, the
Borrower will:

                  (a) Compliance with Laws, Etc. Comply, and cause each of its
         Subsidiaries to comply, in all material respects, with all applicable
         laws, rules, regulations and orders, such compliance to include,
         without limitation, compliance with ERISA and Environmental Laws,
         except to the extent the failure to so comply could not reasonably be
         expected to have a Material Adverse Effect.

                  (b) Payment of Taxes, Etc. Pay and discharge, and cause each
         of its Significant Subsidiaries to pay and discharge, before the same
         shall become delinquent, (i) all taxes, assessments and governmental
         charges or levies imposed upon it or upon its property and (ii) all
         lawful claims that, if unpaid, might by law become a Lien upon its
         property or unless the failure to pay could not reasonably be expected
         to result in a Material Adverse Effect; provided, however, that neither
         the Borrower nor any of its Significant Subsidiaries shall be required
         to pay or discharge any such tax, assessment, charge or claim that is
         being contested in good faith and by proper proceedings and as to which
         appropriate reserves are being maintained or unless the failure to pay
         could not reasonably be expected to result in a Material Adverse
         Effect.

                  (c) Maintenance of Insurance. Maintain, and cause each of its
         Subsidiaries to maintain, insurance with responsible and reputable

                                       31

         risks as is usually carried by companies engaged in similar businesses
         and owning similar properties; provided, however, that the Borrower and
         its Subsidiaries may self-insure to the same extent as other companies
         engaged in similar businesses and owning similar properties and to the
         extent consistent with prudent business practice.

                  (d) Preservation of Corporate Existence, Etc. Preserve and
         maintain, and cause each of its Subsidiaries to preserve and maintain,
         its corporate existence, rights (charter and statutory) and franchises,
         except (other than in the case of the Borrower) to the extent such
         failure could not reasonably be expected to have a Material Adverse
         Effect; provided, however, that the Borrower and its Subsidiaries may
         consummate any merger or consolidation permitted under Section 5.02(b)
         and provided further that neither the Borrower nor any of its
         Subsidiaries shall be required to preserve any right or franchise if
         the board of directors of the Borrower or such Subsidiary shall
         determine that the preservation thereof is no longer desirable in the
         conduct of the business of the Borrower or such Subsidiary, as the case
         may be, and that the loss thereof is not disadvantageous in any
         material respect to the Borrower, such Subsidiary or the Lenders.

                  (e) Visitation Rights. The Borrower will, and will cause each
         of its Subsidiaries to, at any reasonable time and from time to time,
         permit up to six representatives of the Lenders designated by the
         Required Lenders, or representatives of the Agents, on not less than
         five (5) Business Days' notice, to examine and make copies of and
         abstracts from the records and books of account of, and visit the
         properties of, the Borrower and each Significant Subsidiary and to
         discuss the general business affairs of the Borrower and each of its
         Subsidiaries with their respective officers and independent certified
         public accountants; subject, however, in all cases to the imposition of
         such conditions as the Borrower and each of its Significant
         Subsidiaries shall deem necessary based on reasonable considerations of
         safety and security; provided, however, that neither the Borrower nor
         any of its Subsidiaries shall be required to disclose to any Agent, any
         Lender or any agents or representatives thereof any information which
         is the subject of attorney-client privilege or attorney work-product
         privilege properly asserted by the applicable Person to prevent the
         loss of such privilege in connection with such information or which is
         prevented from disclosure pursuant to a confidentiality agreement with
         third parties. Notwithstanding the foregoing, none of the conditions
         precedent to the exercise of the right of access described in the
         preceding sentence that relate to notice requirements or limitations on
         the Persons permitted to exercise such right shall apply at any time
         when a Default or an Event of Default shall have occurred.

                  (f) Keeping of Books. Keep, and cause each of its Subsidiaries
         to keep, proper books of record and account, in which full and correct
         entries shall be made of all financial transactions and the assets and
         business of the Borrower and each such Subsidiary in accordance with
         GAAP.

                  (g) Maintenance of Properties, Etc. Maintain and preserve, and
         cause each of its Subsidiaries to maintain and preserve, all of its
         properties that are used or useful in the conduct of its business in

         working capital purposes, including capital expenditures, of the
         Borrower and its Subsidiaries and the repayment of commercial paper,
         provided, that in no case shall such proceeds be used to repay amounts
         outstanding under the Bridge Credit Agreement.

         which would be obtained in a comparable arm's length transaction with a
         Person not an Affiliate of Borrower or any Subsidiary of Borrower; (B)
         Borrower and any Subsidiary of Borrower may become liable in connection

                                   ARTICLE VII

                                   THE AGENTS

                  SECTION 7.01. Authorization and Action. Each Lender hereby
appoints and authorizes each Agent to take such action as Agent on its behalf
and to exercise such powers and discretion under this Agreement and the other
Loan Documents as are delegated to such Agent by the terms hereof, together with
such powers and discretion as are reasonably incidental thereto. As to any
matters not expressly provided for by this Agreement (including, without
limitation, enforcement or collection of the Notes or CAF Notes, if any), the
Agents shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully protected
in so acting or refraining from acting) upon the instructions of the Required
Lenders, subject, with respect to the Collateral Agent, to Section 8.08, and
such instructions shall be binding upon all Lenders and all holders of Notes or
CAF Notes (if any); provided, however, that neither of the Agents shall be
required to take any action that exposes such Agent to personal liability or
that is contrary to this Agreement or applicable law. Each Agent agrees to give
to each Lender prompt notice of each notice given to it by the Borrower pursuant
to the terms of this Agreement.

                  SECTION 7.02. Agents' Reliance, Etc. Neither the Agents nor
any of their respective directors, officers, agents or employees shall be liable
for any action taken or omitted to be taken by it or them under or in connection
with this Agreement, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, each Agent:
(i) may treat the payee of any Note or CAF Note, as the case may be, as the
holder thereof until the such Agent receives and accepts an Assignment and
Acceptance entered into by the Lender that is the payee of such Note or CAF
Note, as the case may be, as assignor, and an Eligible Assignee, as assignee, as
provided in Section 8.07; (ii) may consult with legal counsel (including counsel
for the Borrower), independent public accountants and other experts selected by
it and shall not be liable for any action taken or omitted to be taken in good
faith by it in accordance with the advice of such counsel, accountants or
experts; (iii) makes no warranty or representation to any Lender and shall not
be responsible to any Lender for any statements, warranties or representations
(whether written or oral) made in or in connection with this Agreement; (iv)
shall not have any duty to ascertain or to inquire as to the performance,
observance or satisfaction of any of the terms, covenants or conditions of this
Agreement on the part of the Borrower or the existence at any time of any
Default or to inspect the property (including the books and records) of the
Borrower; (v) shall not be responsible to any Lender for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of, or, if
applicable, the perfection or priority of any lien or security interest created
or purported to be created under or in connection with, this Agreement or any
other instrument or document furnished pursuant hereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier,
telegram or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

                  SECTION 7.03. CUSA, JPMS and Affiliates. With respect to its
Commitment, the Advances made by it and the Note or CAF Note, if any, issued to
it, CUSA and JPMS shall have the same rights and powers under this Agreement as
any other Lender and may exercise the same as though it were not an Agent; and
the term "Lender" or "Lenders" shall, unless otherwise expressly indicated,
include CUSA and JPMS in their respective individual capacities. CUSA and JPMS
and their respective Affiliates may accept deposits from, lend money to, act as
trustee under indentures of, accept investment banking engagements from and
generally engage in any kind of business with, the Borrower, any of its
Subsidiaries and any Person who may do business with or own securities of the
Borrower or any such Subsidiary, all as if CUSA and JPMS were not Agents and
without any duty to account therefor to the Lenders. The Agents shall have no
duty to disclose any information obtained or received by it or any of its
Affiliates relating to the Borrower or any of its Subsidiaries to the extent
such information was obtained or received in any capacity other than as Agent.

                  SECTION 7.04. Lender Credit Decision. Each Lender acknowledges
that it has, independently and without reliance upon any Agent or any other
Lender and based on the financial statements referred to in Section 4.01 and
such other 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 any Agent or
any other Lender and based on such documents and information as it shall deem

                   CERC 364-Day Revolving Credit Agreement



                                       38

appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

                  SECTION 7.05. Indemnification. The Lenders agree to indemnify
each Agent (to the extent not reimbursed by the Borrower), ratably according to
the respective principal amounts of the Notes (if any) then held by each of them
(or if no Notes are at the time outstanding or if any Notes are held by Persons
that are not Lenders, ratably according to the respective amounts of their
Commitments), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever that may be imposed on, incurred by, or
asserted against such Agent in any way relating to or arising out of this
Agreement or any action taken or omitted by such Agent under this Agreement
(collectively, the "Indemnified Costs"), provided that no Lender shall be liable
for any portion of the Indemnified Costs resulting from such Agent's gross
negligence or willful misconduct. Without limitation of the foregoing, each
Lender agrees to reimburse each Agent promptly upon demand for its ratable share
of any out-of-pocket expenses (including counsel fees) incurred by each Agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, to the extent that such Agent is not
reimbursed for such expenses by the Borrower. In the case of any investigation,
litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05
applies whether any such investigation, litigation or proceeding is brought by
any Agent, any Lender or a third party.

                  SECTION 7.06. Successor Agents. Any Agent may resign at any
time by giving written notice thereof to the Lender Parties and the Borrower and
may be removed at any time with or without cause by the Required Lenders. Upon
any such resignation or removal, the Required Lenders shall have the right to
appoint a successor Agent. If no successor Agent shall have been so appointed by
the Required Lenders, and shall have accepted such appointment, within 30 days
after the retiring Agent's giving of notice of resignation or the Required
Lenders' removal of the retiring Agent, then the retiring Agent may, on behalf
of the Lenders, appoint a successor Agent, which shall be a commercial bank
organized under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations under this
Agreement. After any retiring Agent's resignation or removal hereunder as Agent,
the provisions of this Article VII shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement.

                                  ARTICLE VIII

                                  MISCELLANEOUS

                  SECTION 8.01. Amendments, Etc. No amendment or waiver of any
provision of this Agreement or the Notes (if any), nor consent to any departure
by the Borrower therefrom, shall in any event be effective unless the same shall
be in writing and signed by the Required Lenders, 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 the relevant Lenders, do any of the
following: (a) waive any of the conditions specified in Section 3.01, without
the consent of any affected Lender, (b) increase the Commitments of any affected
Lender, (c) reduce the principal of, or interest on, the Notes (if any) or any
fees or other amounts payable hereunder to such Lender, (d) postpone any date
fixed for any payment of principal of, or interest on, the Notes (if any) or any
fees or other amounts payable hereunder to such Lender, (e) change the
percentage of the Commitments or the aggregate unpaid principal amount of the
Notes (if any), or the number of Lenders, that shall be required for the Lenders
or any of them to take any action hereunder without the consent of all Lenders,
or (f) amend this Section 8.01 without the consent of all Lenders; and provided

or as otherwise specified to the Borrower by the Administrative Agent. All such

a manually executed counterpart thereof.

         (b) So long as CUSA is the Administrative Agent, materials required to

the Administrative Agent in an electronic medium in a format acceptable to the
Administrative Agent and the Lenders by email at oploanswebadmin@citigroup.com,
and if any Lender so requests, delivered to such Lender at its address set forth

Administrative Agent may make such materials, as well as any other written
information, documents, instruments and other material relating to the Borrower,
any of its Subsidiaries or any other materials or matters relating to this
Agreement, the Notes or CAF Notes (if any) or any of the transactions
contemplated hereby (collectively, the "Communications") available to the
Lenders by posting such notices on "e-Disclosure" (the "Platform"), the
Administrative Agent's internet delivery system that is part of SSB Direct,
Global Fixed Income's primary web portal. Although the primary web portal is
secured with a dual firewall and a User ID/Password Authorization System and the
Platform is secured through a single user per deal authorization method whereby
each user may access the Platform only on a deal-by-deal basis, the Borrower
acknowledges that (i) the distribution of material through an electronic medium
is not necessarily secure and that there are confidentiality and other risks
associated with such distribution, (ii) the Platform is provided "as is" and "as
available" and (iii) neither the Administrative Agent nor any of its Affiliates
warrants the accuracy, adequacy or completeness of the Communications or the
Platform and each expressly disclaims liability for errors or omissions in the
Communications or the Platform. No warranty of any kind, express, implied or
statutory, including, without limitation, any warranty of merchantability,
fitness for a particular purpose, non-infringement of third party rights or
freedom from viruses or other code defects, is made by the Administrative Agent
or any of its Affiliates in connection with the Platform.

         (c) Each Lender agrees that notice to it (as provided in the next
sentence) (a "Notice") specifying that any Communications have been posted to
the Platform shall constitute effective delivery of such information, documents
or other materials to such Lender for purposes of this Agreement; provided,
that, if requested by any Lender, the Administrative Agent shall deliver a copy
of the Communications to such Lender by e-mail or telecopier. Each Lender agrees
(i) to notify the Administrative Agent in writing of such Lender's e-mail
address to which a Notice may be sent by electronic transmission (including by
electronic communication) on or before the date such Lender

                   CERC 364-Day Revolving Credit Agreement



                                       40

becomes a party to this Agreement (and from time to time thereafter to ensure
that the Administrative Agent has on record an effective e-mail address for such
Lender) and (ii) that any Notice may be sent to such e-mail address. For
purposes of this Section 8.02(c), the term "Notices" shall only include notices
to be given regarding materials delivered in accordance with Section 8.02(b).

                  SECTION 8.03. No Waiver; Remedies. No failure on the part of
any Lender or Agent to exercise, and no delay in exercising, any right hereunder
or under any Note or CAF Note 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.

                  SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to
pay on demand all reasonable costs and expenses of each Agent and the Lead
Arranger in connection with the preparation, execution, delivery,
administration, modification and amendment of this Agreement, the Notes (if any)
and the other documents to be delivered hereunder, including, without
limitation, (A) all reasonable due diligence, syndication (including printing,
distribution and bank meetings), computer and duplication expenses and (B) the
reasonable fees and expenses of counsel for each Agent and the Lead Arranger
with respect thereto and with respect to advising each Agent as to its rights
and responsibilities under this Agreement. The Borrower further agrees to pay on
demand all costs and expenses of each Agent and the Lenders, if any (including,
without limitation, reasonable counsel fees and expenses), in connection with
the enforcement (whether through negotiations, legal proceedings or otherwise)
of this Agreement, the Notes (if any) and the other documents to be delivered
hereunder, including, without limitation, reasonable fees and expenses of
counsel for each Agent, the Lead Arranger and each Lender in connection with the
enforcement of rights under this Section 8.04(a).

         (b) The Borrower agrees to indemnify and hold harmless each Agent, the
Lead Arranger 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 reasonable
expenses (including, without limitation, reasonable fees and expenses of
counsel) incurred by or asserted or awarded against any Indemnified Party, in
each case arising out of or in connection with or by reason of (including,
without limitation, in connection with any investigation, litigation or
proceeding or preparation of a defense in connection therewith) (i) the Notes or
CAF Notes (if any), this Agreement, any of the transactions contemplated herein
or the actual or proposed use of the proceeds of the Advances or (ii) the actual
or alleged presence of Hazardous Materials on any property of the Borrower or
any of its Subsidiaries or any Environmental Action relating in any way to the
Borrower or any of its Subsidiaries, except to the extent 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. In the case of an investigation,
litigation or other proceeding to which the indemnity in this Section 8.04(b)
applies, such indemnity shall be effective whether or not such investigation,
litigation or proceeding is brought by the Borrower, its directors,
equityholders or creditors or an Indemnified Party or any other Person, whether
or not any Indemnified Party is otherwise a party thereto and whether or not the
transactions contemplated hereby are consummated. The Borrower also agrees not
to assert any claim for special, indirect, consequential or punitive damages
against any Agent, any Lender, any of their Affiliates, or any of their
respective directors, officers, employees, attorneys and agents, on any theory
of liability arising out of or otherwise relating to the Notes or CAF Notes (if
any), this Agreement, any of the transactions contemplated herein or the actual
or proposed use of the proceeds of the Advances.

         (c) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance or CAF Eurodollar Rate Advance is made by the Borrower to or for
the account of a Lender other than on the last day of the Interest Period for
such Advance, as a result of a payment or Conversion pursuant to Sections
2.09(d) or (e), 2.11 or 2.13, acceleration of the maturity of the Notes or CAF
Notes (if any), as the case may be, pursuant to Section 6.01 or for any other
reason, the Borrower shall, upon demand by such 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 that it may reasonably incur as a result of
such payment or Conversion, including, without limitation, any loss, 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.

                                       41

         (d) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
Sections 2.12, 2.15 and 8.04 shall survive the payment in full of principal,
interest and all other amounts payable hereunder and under the Notes or CAF
Notes (if any).

                  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 Notes or CAF Notes, if any, due and
payable pursuant to the provisions of Section 6.01, each Lender and each of its
Affiliates 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 Affiliate to or for
the credit or the account of the Borrower against any and all of the obligations
of the Borrower now or hereafter existing under this Agreement and the Note or
CAF Note, as the case may be, held by such Lender, whether or not such Lender
shall have made any demand under this Agreement or such Note or CAF Note and
although such obligations may be unmatured. Each Lender agrees promptly to
notify the Borrower after any such set-off and application, provided that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender and its Affiliates under this Section are
in addition to other rights and remedies (including, without limitation, other
rights of set-off) that such Lender and its Affiliates may have.

                  SECTION 8.06. Binding Effect. This Agreement shall become
effective (other than Sections 2.01 and 2.03, which shall only become effective
upon satisfaction of the conditions precedent set forth in Section 3.01) when it
shall have been executed by the Borrower and each Agent and when the
Administrative Agent shall have been notified by each Initial Lender that such
Initial Lender has executed it and thereafter shall be binding upon and inure to
the benefit of the Borrower, each Agent and each Lender and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights hereunder or any interest herein without the prior written
consent of the Lenders.

                  SECTION 8.07. Assignments and Participations. (a) Each Lender
may assign to one or more Persons all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment, the Revolving Advances owing to it and the Note or Notes, if any,
held by 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 (other than any right to make CAF Advances, CAF Advances owing to it
and CAF Note or CAF Notes, if any), (ii) except in the case of an assignment to
a Person that, immediately prior to such assignment, was a Lender or an
assignment of all of a Lender's rights and obligations under this Agreement, 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 an
integral multiple of $1,000,000 in excess thereof, (iii) each such assignment
shall be to an Eligible Assignee, (iv) 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 any Note,
if any, subject to such assignment, and (v) the parties to each such assignment
shall deliver to the Administrative Agent a processing and recordation fee of
$3,500. 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 its rights under Sections 2.13, 2.16 and 8.04
to the extent any claim thereunder relates to an event arising prior to such
assignment) 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).

         (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
Borrower or

                   CERC 364-Day Revolving Credit Agreement



                                       42

the performance or observance by the Borrower of any of its obligations under
this Agreement or any other instrument or document furnished pursuant hereto;
(iii) such assignee confirms that it has received a copy of this Agreement,
together with copies of the financial statements referred to in Section 4.01 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 any 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 assignee appoints and
authorizes each Agent to take such action as agent on its behalf and to exercise
such powers and discretion under this Agreement as are delegated to such Agent
by the terms hereof, together with such powers and discretion as are reasonably
incidental thereto; and (vii) such assignee agrees that it will perform in
accordance with their terms all of the obligations that by the terms of this
Agreement are required to be performed by it as a Lender.

         (c) 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
the Lenders and the Commitment of, and principal amount of the Advances owing
to, each Lender from time to time (the "Register"). The entries in the Register
shall be prima facie evidence of the correctness thereof, and the Borrower, the
Agents and the Lenders may treat each Person whose name is recorded in the
Register as a Lender hereunder for all purposes of this Agreement. The Register
shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

         (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note, if any, subject to such assignment, the Administrative
Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit C hereto, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Borrower. Within five Business Days
after its receipt of such notice, the Borrower, at its own expense, shall
execute and deliver to the Administrative Agent in exchange for the surrendered
Note a new Note to the order of such Eligible Assignee in an amount equal to the
Commitment assumed by it pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained a Commitment hereunder, a new Note to the order of
the assigning Lender in an amount equal to the Commitment retained by it
hereunder. Such new Note shall be in an aggregate principal amount equal to the
aggregate principal amount of such surrendered Note or Notes, shall be dated the
effective date of such Assignment and Acceptance and shall otherwise be in
substantially the form of Exhibit A hereto.

         (e) Each Lender may sell participations to one or more banks or other
entities (other than the Borrower or any of its Affiliates) 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, the Advances owing to it and the
Note or Notes, if any, held by it); provided, however, that (i) such Lender's
obligations under this Agreement (including, without limitation, its Commitment
to the Borrower 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 Note for all
purposes of this Agreement, (iv) the Borrower, the Agents 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) no participant
under any such participation shall have any right to approve any amendment or
waiver of any provision of this Agreement or any Note, or any consent to any
departure by the Borrower therefrom, except to the extent that such amendment,
waiver or consent would reduce the principal of, or interest on, the Notes or
any fees or other amounts payable hereunder, in each case to the extent subject
to such participation, or postpone any date fixed for any payment of principal
of, or interest on, the Notes or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation.

         (f) 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 Borrower furnished to such Lender by or on behalf of
the Borrower; provided 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 Borrower
received by it from such Lender.

                                       43

         (g) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time and without the consent of the Borrower or any Agent
(i) create a security interest in all or any portion of its rights under this
Agreement (including, without limitation, the Advances owing to it and the Note
or Notes held by it) in favor of any Federal Reserve Bank in accordance with
Regulation A of the Board of Governors of the Federal Reserve System, and (ii)
with notice to the Borrower and the Administrative Agent, assign all or part of
its rights and obligations under this Agreement to any of its Affiliates.

         (h) In the event that any Lender requests payments of reimbursement,
compensation or indemnification from the Borrower pursuant to Sections 2.02,
2.12 or 2.15 herein, then the Borrower shall have the right, but not the
obligation, at its own expense, upon 5 Business Days notice to such Lender and
the Administrative Agent, to replace such Lender with an assignee (in accordance
with and subject to the restrictions contained in paragraphs (a) and (b) above),
and such Lender hereby agrees to transfer and assign without recourse (in
accordance with and subject to the restrictions contained in paragraphs (a) and
(b) above) all its interests, rights and obligations in respect of its
Commitment to such assignee; provided, however, that (i) no such assignment
shall conflict with any law, rule and regulation or order of any governmental
authority, (ii) no Default has occurred or is continuing, (iii) the Borrower has
satisfied all of its obligations under this Agreement relating to such assigning
Lender through the date of such assignment, (iv) the Borrower shall pay to the
Administrative Agent the administrative fee in the amount of $3,500 if such
replacement Lender assignee is not an existing Lender, and (v) such assignee
shall pay to such assigning Lender in immediately available funds on the date of
such assignment the principal of and interest accrued to the date of payment on
the Advances made by such Lender hereunder and the Borrower, the Administrative
Agent or such assignee, as applicable, shall pay to such Lender all other
amounts accrued for such Lender's account or owed to it hereunder.

                  SECTION 8.08. Collateral. The Lenders acknowledge and agree
that their rights under the Pledge Agreement will be limited as set forth
therein. In particular, the rights of the Lenders under the Pledge Agreement
will be limited to their right to share in the proceeds of the Collateral as
provided therein, and they shall have no rights to direct actions of the
Collateral Agent thereunder. The security interest in the Collateral to be
granted in favor of the Lenders shall be automatically released at such time as
the security interest granted therein in favor of the Bridge Secured Parties (as
defined in the Pledge Agreement) has been released and terminated in accordance
with the terms of the Pledge Agreement.

                  SECTION 8.09. Confidentiality. Neither Agent nor any Lender
shall disclose any Confidential Information to any other Person without the
consent of the Borrower, other than (a) to such Agent's or such Lender's
Affiliates and their officers, directors, employees, agents and advisors and, as
contemplated by Section 8.07(f), to actual or prospective 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 or
any other regulatory or self-regulatory authorities. The Borrower may disclose
to any and all Persons, without limitation of any kind, the U.S. tax treatment
and U.S. tax structure of the transactions contemplated by this Agreement and
all materials of any kind (including opinions or other tax analyses) that are
provided to the Borrower relating to such U.S. tax treatment and U.S. tax
structure.

                  SECTION 8.10. Governing Law. This Agreement and the Notes (if
any) shall be governed by, and construed in accordance with, the laws of the
State of New York.

                  SECTION 8.11. 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. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

                  SECTION 8.12. Jurisdiction, Etc. (a) Each of the parties
hereto 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 New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the Notes or CAF Notes (if any), 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 any such

Each of the parties hereto agrees that a final judgment in any such action or

Agreement shall affect any right that any party may otherwise have to bring any
action or proceeding relating to this Agreement or the Notes or CAF Notes (if
any) in the courts of any jurisdiction.

         (b) Each of the parties hereto irrevocably and unconditionally waives,
to the fullest extent it may legally and effectively do so, any objection that
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 the Notes or CAF
Notes (if any) 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

                  The Borrower promises to pay interest on the unpaid principal
amount of each Revolving Advance from the date of such Revolving Advance until

among other things, (i) provides for the making of Revolving Advances by the

indebtedness of the Borrower resulting from each such Revolving Advance being
evidenced by this Promissory Note, and (ii) contains provisions for acceleration
of the maturity hereof upon the happening of certain stated events and also for
prepayments on account of principal hereof prior to the maturity hereof upon the

         Credit Agreement; (iii) confirms that it is an Eligible Assignee; (iv)
         appoints and authorizes each Agent to take such action as such Agent on

         Agreement as are delegated to such Agent by the terms thereof, together
         with such powers and discretion as are reasonably incidental thereto;
         (v) agrees that it will perform in accordance with their terms all of

         to be performed by it as a Lender; and (vi) attaches any U.S. Internal
         Revenue Service forms required under Section 2.15 of the Credit

                  (1)      The Grantor has entered into a U.S.$200,000,000
Credit Agreement, dated March 25, 2003 (said Credit Agreement, as it may
hereafter be amended, amended and restated, supplemented or otherwise modified
from time to time, being the "REVOLVING CREDIT AGREEMENT") among the Grantor, as
borrower, Salomon Smith Barney, Inc. and J.P. Morgan Securities Inc. as lead

Banc One Capital Markets, Inc., as co-syndication agents, Credit Suisse First
Boston, Cayman Islands Branch, as documentation agent, Citicorp USA, Inc., as

signature pages thereto (the "REVOLVER LENDERS" and, together with the Revolver
Arrangers and the Revolver Agent, the "REVOLVER SECURED PARTIES").

                  (2)      The Grantor has also entered into a Bridge Credit
Agreement, dated March [__], 2003 (said Bridge Credit Agreement, as it may
hereafter be amended, amended and restated, supplemented or otherwise modified
from time to time, being the "BRIDGE CREDIT AGREEMENT" and, together with the
Revolving Credit Agreement, the "CREDIT AGREEMENTS") among the Grantor, as
borrower, Citicorp North America, Inc., as administrative agent (the "BRIDGE
AGENT"), Salomon Smith Barney, Inc. as lead arranger (the "BRIDGE ARRANGER") and
the lenders listed on the signature pages thereto (the "BRIDGE LENDERS" and,
together with the Bridge Agent and the Bridge Arranger, the "BRIDGE SECURED
PARTIES" and, together with the Revolver Secured Parties, the "SECURED
PARTIES"). Terms defined in the Credit Agreements and not otherwise defined in

                  (3)      Pursuant to the Credit Agreements, the Grantor is

other equity interests (the "INITIAL PLEDGED EQUITY") set forth opposite the
Grantor's name on and as otherwise described in Schedule II hereto and issued by
the Persons named therein and of the indebtedness (the "INITIAL PLEDGED DEBT")

                  (6)      Unless otherwise defined in this Agreement or in the
Credit Agreements, terms defined in Article 8 or 9 of the UCC (as defined below)
are used in this Agreement as such terms are defined in such Article 8 or 9.
"UCC" means the Uniform Commercial Code as in effect, from time to time, in the
State of New York; provided that, if perfection or the effect of perfection or
non-perfection or the priority of any security interest in any Collateral is
governed by the Uniform Commercial Code as in effect in a jurisdiction other
than the State of New York, "UCC" means the Uniform Commercial Code as in effect
from time to time in such other jurisdiction for purposes of the provisions
hereof relating to such perfection, effect of perfection or non-perfection or
priority.

                  NOW, THEREFORE, in consideration of the premises and in order
to induce the Bridge Lenders to make Advances under the Bridge Credit Agreement

Credit Agreement, the Grantor hereby agrees with the Collateral Agent for the
ratable benefit of the Secured Parties as follows:

                  Section 1.        Grant of Security. The Grantor hereby grants

                  (a)      the following (the "SECURITY COLLATERAL"):

                           (i)      the Initial Pledged Equity and the

                  instruments and other property from time to time received,
                  receivable or otherwise distributed in respect of or in
                  exchange for any or all of the Initial Pledged Equity and all

                  Equity or any successor entity from time to time acquired by
                  the Grantor in any manner (such shares and other Equity
                  Interests, together with the Initial Pledged Equity, being the
                  "PLEDGED EQUITY"), and the certificates, if any, representing
                  such additional shares or other Equity Interests, and all
                  dividends, distributions, return of capital, cash, instruments
                  and other property from time to time received, receivable or
                  otherwise distributed in respect of or in exchange for any or
                  all of such shares or other Equity Interests and all
                  subscription warrants, rights or options issued thereon or
                  with respect thereto;

                           (iii)    the Initial Pledged Debt and the
                  instruments, if any, evidencing the Initial Pledged Debt, and
                  all interest, cash, instruments and other property from time
                  to time received, receivable or otherwise distributed in
                  respect of or in exchange for any or all of the Initial
                  Pledged Debt; and

                  (b)      all proceeds of, collateral for, income and other
         payments now or hereafter due and payable with respect to, and
         supporting obligations relating to, any and all of the

                            CERC - Pledge Agreement



                                       3

         Collateral (including, without limitation, proceeds, collateral and
         supporting obligations that constitute property of the types described
         in clause (a) of this Section 1 and this clause (b)).

                  Section 2.         Security for Obligations. This Agreement
secures, in the case of the Grantor, the payment of all obligations of the
Grantor now or hereafter existing under the Loan Documents, as defined in the
Bridge Credit Agreement ("BRIDGE OBLIGATIONS") and under the Loan Documents, as
defined in the Revolving Credit Agreement ("REVOLVER OBLIGATIONS"), whether
direct or indirect, absolute or contingent, and whether for principal,
reimbursement obligations, interest, fees, premiums, penalties,
indemnifications, contract causes of action, costs, expenses or otherwise (all
such obligations being the "SECURED OBLIGATIONS").

                  Section 3.        Delivery and Control of Security Collateral.
(a) All certificates or instruments representing or evidencing Security
Collateral shall be delivered to and held by or on behalf of the Collateral
Agent pursuant hereto and shall be in suitable form for transfer by delivery, or
shall be accompanied by duly executed instruments of transfer or assignment in
blank, all in form and substance satisfactory to the Collateral Agent. The
Collateral Agent shall have the right, at any time after the occurrence and
during the continuation of an Event of Default, in its reasonable discretion and
without notice to the Grantor, to transfer to or to register in the name of the
Collateral Agent or any of its nominees any or all of the Security Collateral,
subject only to the revocable rights specified in Section 7(a). In addition,
after the occurrence and during the continuation of an Event of Default, the
Collateral Agent shall have the right to exchange certificates or instruments
representing or evidencing Security Collateral for certificates or instruments
of smaller or larger denominations.

                  (b)      With respect to any Security Collateral in which the
Grantor has any right, title or interest and that constitutes an uncertificated
security, the Grantor will cause the issuer thereof either (i) to register the
Collateral Agent as the registered owner of such security or (ii) to agree in an
authenticated record with the Grantor and the Collateral Agent that such issuer
will comply with instructions with respect to such security originated by the
Collateral Agent without further consent of the Grantor, such authenticated
record to be in form and substance satisfactory to the Collateral Agent. With
respect to any Security Collateral in which the Grantor has any right, title or
interest and that is not an uncertificated security, upon the request of the
Collateral Agent upon the occurrence and during the continuance of an Event of
Default, the Grantor will notify each such issuer of Pledged Equity that such
Pledged Equity is subject to the security interest granted hereunder.

                  (c)      Upon the request of the Collateral Agent, such
Grantor will notify the issuer of the Initial Pledged Debt that such Initial
Pledged Debt is subject to the security interest granted hereunder.

                  Section 4.        Representations and Warranties. The Grantor
represents and warrants as follows:

                  (a)      The Grantor's exact legal name, as defined in Section
         9-503(a) of the UCC, is correctly set forth in Schedule 1 hereto. The
         Grantor is located (within the meaning of Section 9-307 of the UCC) and
         has its chief executive office in the state or

                            CERC - Pledge Agreement



                                       4

         jurisdiction set forth in Schedule I hereto. The information set forth
         in Schedule I hereto with respect to the Grantor is true and accurate
         in all respects. The Grantor has not previously changed its name,
         location, chief executive office, type of organization, jurisdiction of
         organization or organizational identification number from those set
         forth in Schedule I hereto except as disclosed in Schedule III hereto.

                  (b)      The Grantor is the legal and beneficial owner of the
         Collateral of the Grantor free and clear of any Lien, claim, option or
         right of others, except for the security interest created under this
         Agreement or as otherwise permitted under each Credit Agreement. No
         effective financing statement or other instrument similar in effect
         covering all or any part of such Collateral or listing the Grantor or
         any trade name of the Grantor as debtor is on file in any recording
         office, except such as may have been filed in favor of the Collateral
         Agent relating to the Loan Documents or as otherwise permitted under
         each Credit Agreement.

                  (c)      The Pledged Equity pledged by the Grantor hereunder
         has been duly authorized and validly issued and is fully paid and
         non-assessable. With respect to any Pledged Equity that is an
         uncertificated security, the Grantor has caused the issuer thereof
         either (i) to register the Collateral Agent as the registered owner of
         such security or (ii) to agree in an authenticated record with the
         Grantor and the Collateral Agent that such issuer will, upon the
         occurrence and during the continuation of an Event of Default, comply
         with instructions with respect to such security originated by the
         Collateral Agent without further consent of the Grantor. The Initial
         Pledged Debt pledged by such Grantor hereunder has been duly
         authorized, authenticated or issued and delivered, is the legal, valid
         and binding obligation of the issuers thereof, is evidenced by one or
         more promissory notes (which notes have been delivered to the
         Collateral Agent) and is not in default.

                  (d)      The Initial Pledged Equity pledged by the Grantor
         constitutes the percentage of the issued and outstanding Equity
         Interests of the issuers thereof indicated on Schedule II hereto. The
         Initial Pledged Debt constitutes all of the outstanding indebtedness
         owed to such Grantor by the issuer thereof and is outstanding in the
         principal amount indicated on Schedule II hereto.

                  (e)      All filings and other actions (including, without
         limitation, actions necessary to obtain control of Collateral as

         and continuation statements under the UCC, which financing statements
         have been duly filed and are in full force and effect, and the actions
         described in Section 3 with respect to Security Collateral, which
         actions have been taken and are in full force and effect, or (iii) the

         with the disposition of any portion of the Security Collateral by laws
         affecting the offering and sale of securities generally.

                  Section 5.        Further Assurances. (a) The Grantor agrees
that from time to time, at the expense of the Grantor, the Grantor will promptly
execute and deliver, or otherwise authenticate, all further instruments and
documents, and take all further action that may be necessary or desirable, or
that the Collateral Agent may reasonably request, in order to perfect and
protect any pledge or security interest granted or purported to be granted by
the Grantor hereunder or to enable the Collateral Agent to exercise and enforce
its rights and remedies hereunder with respect to any Collateral of the Grantor.
Without limiting the generality of the foregoing, the Grantor will promptly with
respect to Collateral of the Grantor: (i) if any such Collateral shall be
evidenced by a promissory note or other instrument, deliver and pledge to the
Collateral Agent hereunder such note or instrument duly indorsed and accompanied
by duly executed instruments of transfer or assignment, all in form and
substance satisfactory to the Collateral Agent; (ii) execute or authenticate and
file such financing or continuation statements, or amendments thereto, and such
other instruments or notices, as may be necessary or desirable, or as the
Collateral Agent may request, in order to perfect and preserve the security
interest granted or purported to be granted by the Grantor hereunder; (iii)
deliver and pledge to the Collateral Agent for benefit of the Secured Parties
certificates representing Security Collateral that constitutes certificated
securities, accompanied by undated stock or bond powers executed in blank; (iv)

the Collateral Agent may deem reasonably necessary or desirable in order to
perfect and protect the security interest created by the Grantor under this
Agreement has been taken.

                  (b)      The Grantor hereby authorizes the Collateral Agent to
file one or more financing or continuation statements, and amendments thereto,
in each case without the signature of the Grantor, and regardless of whether any
particular asset described in such financing statements falls within the scope
of the UCC or the granting clause of this Agreement. A photocopy or other
reproduction of this Agreement or any financing statement covering the
Collateral or any part thereof shall be sufficient as a financing statement
where permitted by law. The Grantor ratifies its authorization for the
Collateral Agent to have filed such financing statements, continuation
statements or amendments filed prior to the date hereof.

                  (c)      The Grantor will furnish to the Collateral Agent from
time to time statements and schedules further identifying and describing the
Collateral of the Grantor and such other reports in connection with such
Collateral as the Collateral Agent may reasonably request, all in reasonable
detail.

                  Section 6.        Post-Closing Changes. (a) The Grantor will
not change its name, type of organization, jurisdiction of organization,
organizational identification number or location from those set forth in Section
4(a) of this Agreement without first giving at least 10 Business Days' prior
written notice to the Collateral Agent and taking all action required by the
Collateral Agent for the purpose of perfecting or protecting the security
interest granted by this Agreement. The Grantor will not become bound by a
security agreement authenticated by another Person (determined as provided in
Section 9-203(d) of the UCC) without giving the Collateral Agent 10 Business
Days' prior written notice thereof and taking all action required by the
Collateral Agent to ensure that the perfection and first priority nature of the
Collateral Agent's security interest in the Collateral will be maintained.

                  (b)      The Grantor will hold and preserve its records
relating to the Collateral and will permit up to six representatives of the
Bridge Secured Parties designated by the Required Lenders (as defined in the
Bridge Credit Agreement) or representatives of the Collateral Agent, on not less
than five (5) Business Days' notice, at any reasonable time during normal
business hours, to inspect and make copies of abstracts from such records and
other documents and to discuss general business affairs of the Grantor with its
officers; subject, however, in all cases to the imposition of such conditions as
the Grantor shall deem necessary based on reasonable considerations of safety
and security; provided, however, that the Grantor shall not be required to
disclose to the Collateral Agent or any Secured Party or representatives thereof
any information which is the subject of attorney-client privilege or attorney
work-product privilege properly asserted by the Grantor to prevent the loss of
such privilege in connection with such information or which is prevented from
disclosure pursuant to a confidentiality agreement with third parties.
Notwithstanding the foregoing, none of the conditions as to the exercise of the
right of access described in the preceding sentence that relate to notice
requirements or limitations on the Persons permitted to exercise such right
shall apply at any time when a Default or an Event of Default shall have
occurred (as each such term is defined in either of the Credit Agreements).

                  (c)      If the Grantor does not have an organizational
identification number and later obtains one, it will forthwith notify the
Collateral Agent of such organizational identification number.

                  Section 7.        Voting Rights; Dividends; Etc. (a) So long
as no Event of Default shall have occurred and be continuing:

                  (i)      The Grantor shall be entitled to exercise any and all
         voting and other consensual rights pertaining to the Security
         Collateral or any part thereof for any purpose; provided however, that
         the Grantor will not exercise or refrain from exercising any such right
         if such action would have a material adverse effect on the value of the
         Security Collateral or any part thereof.

                  (ii)     The Grantor shall be entitled to receive and retain
         any and all dividends, interest and other distributions paid in respect
         of the Security Collateral if and to the extent that the payment
         thereof is not otherwise prohibited by the terms of the Loan Documents;
         provided, however, that any and all

                           (A)      dividends, interest and other distributions
                  paid or payable other than in cash in respect of, and
                  instruments and other property received, receivable or

                  payable in cash in respect of any Security Collateral in
                  connection with a partial or total liquidation or dissolution
                  or in connection with a material reduction of capital, capital
                  surplus or paid-in-surplus and

                           (C)      cash paid, payable or otherwise distributed
                  in redemption of, or in exchange for, any Security Collateral

         shall be, and shall be forthwith delivered to the Collateral Agent to
         hold as, Security Collateral and shall, if received by the Grantor, be
         received in trust for the benefit of the Collateral Agent, be
         segregated from the other property or funds of the Grantor and be
         forthwith delivered to the Collateral Agent as Security Collateral in
         the same form as so received (with any necessary indorsement).

                  (iii)    The Collateral Agent will execute and deliver (or
         cause to be executed and delivered) to the Grantor all such proxies and
         other instruments as the Grantor may reasonably request for the purpose
         of enabling the Grantor to exercise the voting and other rights that it
         is entitled to exercise pursuant to paragraph (i) above and to receive
         the dividends or interest payments that it is authorized to receive and
         retain pursuant to paragraph (ii) above.

                  (b)      Upon the occurrence and during the continuance of an
         Event of Default:

                  (i)      All rights of the Grantor (x) to exercise or refrain
         from exercising the voting and other consensual rights that it would
         otherwise be entitled to exercise pursuant to Section 7(a)(i) shall,
         upon notice to the Grantor by the Collateral Agent, cease and (y) to
         receive the dividends, interest and other distributions that it would
         otherwise be authorized to receive and retain pursuant to Section
         7(a)(ii) shall automatically cease, and all such rights shall thereupon
         become vested in the Collateral Agent, which shall thereupon have the
         sole right to exercise or refrain from exercising such voting and other
         consensual rights and to receive and hold as Security Collateral such
         dividends, interest and other distributions.

                  (ii)     All dividends, interest and other distributions that
         are received by the Grantor contrary to the provisions of paragraph (i)
         of this Section 7(b) shall be received in trust for the benefit of the
         Collateral Agent, shall be segregated from other funds of the Grantor
         and shall be forthwith paid over to the Collateral Agent as Security
         Collateral in the same form as so received (with any necessary
         indorsement).

                  Section 8.        Transfers and Other Liens; Additional
Shares. (a) The Grantor agrees that it will not (i) sell, assign or otherwise
dispose of, or grant any option with respect to, any of the Collateral, other
than sales, assignments and other dispositions of Collateral, and options
relating to Collateral, permitted under the terms of the Credit Agreements, or
(ii) create

or suffer to exist any Lien upon or with respect to any of the Collateral of the
Grantor except for the pledge, assignment and security interest created under
this Agreement and Permitted Liens.

                  (b)      The Grantor agrees that it will (i) cause each issuer
of the Pledged Equity pledged by the Grantor not to issue any Equity Interests
or other securities in addition to or in substitution for the Pledged Equity
issued by such issuer, except to the Grantor, and (ii) pledge hereunder,
immediately upon its acquisition (directly or indirectly) thereof, any and all
additional Equity Interests or other securities of each issuer of the Pledged
Equity.

                  Section 9.        Collateral Agent Appointed Attorney-in-Fact.
The Grantor hereby irrevocably appoints the Collateral Agent the Grantor's
attorney-in-fact, with full authority in the place and stead of the Grantor and
in the name of the Grantor or otherwise, from time to time, upon the occurrence
and during the continuance of an Event of Default, in the Collateral Agent's
reasonable discretion, to take any action and to execute any instrument that the
Collateral Agent may deem necessary or advisable to accomplish the purposes of
this Agreement, including, without limitation:

                  (a)      to ask for, demand, collect, sue for, recover,
         compromise, receive and give acquittance and receipts for moneys due
         and to become due under or in respect of any of the Collateral,

                  (b)      to receive, indorse and collect any drafts or other
         instruments, documents and chattel paper, in connection with clause (a)
         above, and

                  (c)      to file any claims or take any action or institute
         any proceedings that the Collateral Agent may deem necessary or
         desirable for the collection of any of the Collateral or otherwise to
         enforce the rights of the Collateral Agent with respect to any of the
         Collateral.

                  Section 10.       Collateral Agent May Perform. If the Grantor
fails to perform any agreement contained herein, the Collateral Agent may, but
without any obligation to do so and without notice, itself perform, or cause
performance of, such agreement, and the reasonable expenses of the Collateral
Agent incurred in connection therewith shall be payable by the Grantor under
Section 13.

                  Section 11.       The Collateral Agent's Duties. (a) The
powers conferred on the Collateral Agent hereunder are solely to protect the
Secured Parties' interest in the Collateral and shall not impose any duty upon
it to exercise any such powers. Except for the safe custody of any Collateral in
its possession and the accounting for moneys actually received by it hereunder,
the Collateral Agent shall have no duty as to any Collateral, as to ascertaining
or taking action with respect to calls, conversions, exchanges, maturities,
tenders or other matters relative to any Collateral, whether or not any Secured
Party has or is deemed to have knowledge of such matters, or as to the taking of
any necessary steps to preserve rights against any parties or any other rights
pertaining to any Collateral. The Collateral Agent shall be deemed to have
exercised reasonable care in the custody and preservation of any Collateral in
its possession if such Collateral is accorded treatment substantially equal to
that which it accords its own property.

                  (b)      Anything contained herein to the contrary
notwithstanding, the Collateral Agent may from time to time, when the Collateral
Agent deems it to be necessary with (so long as an Event of Default has not
occurred and is continuing) the written concurrence of the Grantor, appoint one
or more subagents (each a "SUBAGENT") for the Collateral Agent hereunder with
respect to all or any part of the Collateral. In the event that the Collateral
Agent so appoints any Subagent with respect to any Collateral, (i) the
assignment and pledge of such Collateral and the security interest granted in
such Collateral by the Grantor hereunder shall be deemed for purposes of this
Pledge Agreement to have been made to such Subagent, in addition to the
Collateral Agent, for the ratable benefit of the Secured Parties, as security
for the Secured Obligations of the Grantor, (ii) such Subagent shall
automatically be vested, in addition to the Collateral Agent, with all rights,
powers, privileges, interests and remedies of the Collateral Agent hereunder
with respect to such Collateral, and (iii) the term "Collateral Agent," when
used herein in relation to any rights, powers, privileges, interests and
remedies of the Collateral Agent with respect to such Collateral, shall include
such Subagent; provided, however, that no such Subagent shall be authorized to
take any action with respect to any such Collateral unless and except to the
extent expressly authorized in writing by the Collateral Agent.

                  Section 12.       Remedies. If any Event of Default shall have
occurred and be continuing:

                  (a)      The Collateral Agent may exercise in respect of the
         Collateral, in addition to other rights and remedies provided for
         herein or otherwise available to it, all the rights and remedies of a
         secured party upon default under the UCC (whether or not the UCC
         applies to the affected Collateral) and also may: (i) require the
         Grantor to, and the Grantor hereby agrees that it will at its expense
         and upon request of the Collateral Agent forthwith, assemble all or
         part of the Collateral as directed by the Collateral Agent and make it
         available to the Collateral Agent at a place and time to be designated
         by the Collateral Agent that is reasonably convenient to both parties;
         (ii) without notice except as specified below, sell the Collateral or
         any part thereof in one or more parcels at public or private sale, at
         any of the Collateral Agent's offices or elsewhere, for cash, on credit
         or for future delivery, and upon such other terms as the Collateral
         Agent may deem commercially reasonable; and (iii) exercise any and all
         rights and remedies of any of the Grantor under or in connection with
         the Collateral, or otherwise in respect of the Collateral, including,
         without limitation, (A) rights of the Grantor to demand or otherwise
         require payment of any amount with respect to the Collateral and (B)
         exercise all other rights and remedies with respect to the Collateral.
         The Grantor agrees that, to the extent notice of sale shall be required
         by law, at least ten days' notice to the Grantor of the time and place
         of any public sale or the time after which any private sale is to be
         made shall constitute reasonable notification. The Collateral Agent
         shall not be obligated to make any sale of Collateral regardless of
         notice of sale having been given. The Collateral Agent may adjourn any
         public or private sale from time to time by announcement at the time
         and place fixed therefor, and such sale may, without further notice, be
         made at the time and place to which it was so adjourned.

                  (b)      Any cash held by or on behalf of the Collateral Agent
         and all cash proceeds received by or on behalf of the Collateral Agent
         in respect of any sale of, collection from, or other realization upon
         all or any part of the Collateral may, in the

         discretion of the Collateral Agent, be held by the Collateral Agent as
         collateral for, and/or then or at any time thereafter applied (after
         payment of any amounts payable to the Collateral Agent pursuant to
         Section 13) in whole or in part by the Collateral Agent for the ratable
         benefit of the Secured Parties against, all or any part of the Secured
         Obligations, in the following manner:

                           (i)      first, paid to the Agents for any amounts
                  then owing to the Agents pursuant to Section 8.04 of each of
                  the Credit Agreements or otherwise under the Loan Documents,
                  ratably in accordance with such respective amounts then owing
                  to the Agents; and

                           (ii)     second, paid to the Lenders for any amounts
                  then owing to them, in their capacities as such, under the
                  Loan Documents ratably in accordance with such respective
                  amounts then owing to such Lenders.

         Any surplus of such cash or cash proceeds held by or on the behalf of
         the Collateral Agent and remaining after payment in full of all the
         Secured Obligations shall be paid over to the Grantor or to whomsoever
         may be lawfully entitled to receive such surplus.

                  (c)      All payments received by the Grantor in respect of
         the Collateral shall be received in trust for the benefit of the
         Collateral Agent, shall be segregated from other funds of the Grantor
         and shall be forthwith paid over to the Collateral Agent in the same
         form as so received (with any necessary indorsement).

                  (d)      The Collateral Agent may, without notice to the
         Grantor except as required by law and at any time or from time to time,
         charge, set-off and otherwise apply all or any part of the Secured
         Obligations against any funds held in any deposit account.

                  Section 13.       Indemnity and Expenses. (a) The Grantor
agrees to indemnify, defend and save and hold harmless each Secured Party and
each of their Affiliates and their respective officers, directors, employees,
agents and advisors (each, an "INDEMNIFIED PARTY") from and against, and shall
pay on demand, 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 resulting from this Agreement
(including, without limitation, enforcement of this Agreement), except to the
extent 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.

                  (b)      The Grantor will upon demand pay to the Collateral
Agent the amount of any and all reasonable expenses, including, without
limitation, the reasonable fees and expenses of its counsel and of any experts
and agents, that the Collateral Agent may incur in connection with (i) the
administration of this Agreement, (ii) the custody, preservation, use or
operation of, or the sale of, collection from or other realization upon, any of
the Collateral, (iii) the exercise or enforcement of any of the rights of the
Collateral Agent or the other Secured Parties hereunder or (iv) the failure by
the Grantor to perform or observe any of the provisions hereof.

of any provision of this Agreement, and no consent to any departure by the
Grantor herefrom, shall in any event be effective unless the same shall be in
writing and signed by the Collateral Agent, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given. No failure on the part of the Collateral Agent or any other
Secured Party 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.

                  Section 15.       Notices, Etc. All notices and other

Agreement or Schedule hereto shall be effective as delivery of an original
executed counterpart thereof.

                  Section 16.       Continuing Security Interest; Assignments
under the Credit Agreements. This Agreement shall create a continuing security
interest in the Collateral and shall (a) remain in full force and effect until
the later of (i) the payment in full in cash of the Secured Obligations
consisting of Bridge Obligations and (ii) the Termination Date (as defined in
the Bridge Credit Agreement), (b) be binding upon the Grantor, its successors
and assigns and (c) inure, together with the rights and remedies of the
