the Borrower or the Required Lenders shall so request, the Administrative Agent,
the Lenders and the Borrower shall negotiate in good faith to amend such ratio
or requirement to preserve the original intent thereof in light of such change
in GAAP (subject to the approval of the Required Lenders); provided that, until
so amended, (i) such ratio or requirement shall continue to be computed in
accordance with GAAP prior to such change therein and (ii) the Borrower shall
provide to the Administrative Agent and the Lenders financial statements and
other documents required under this Agreement or as reasonably requested
hereunder setting forth a reconciliation between calculations of such ratio or
requirement made before and after giving effect to such change in GAAP.

         1.04 ROUNDING. Any financial ratios required to be maintained by the
Borrower pursuant to this Agreement shall be calculated by dividing the
appropriate component by the other component, carrying the result to one place
more than the number of places by which such ratio is expressed herein and
rounding the result up or down to the nearest number (with a rounding-up if
there is no nearest number).

         1.05 REFERENCES TO AGREEMENTS AND LAWS. Unless otherwise expressly
provided herein, (a) references to Organization Documents, agreements (including
the Loan Documents) and other contractual instruments shall be deemed to include
all subsequent amendments, restatements, extensions, supplements and other
modifications thereto, but only to the extent that such amendments,
restatements, extensions, supplements and other modifications are not prohibited
by any Loan Document; and (b) references to any Law shall include all statutory
and regulatory provisions consolidating, amending, replacing, supplementing or
interpreting such Law.

         1.06 TIMES OF DAY. Unless otherwise specified, all references herein to
times of day shall be references to Eastern time (daylight or standard, as
applicable).

                                   ARTICLE II.
                         THE COMMITMENTS AND BORROWINGS

         2.01 LOANS. Subject to the terms and conditions set forth herein, each
Lender severally agrees to make a loan (each such loan, a "Loan") to the
Borrower on the Closing Date in an aggregate amount equal to such Lender's
Commitment. The Loans made on the Closing Date will be Eurodollar Rate Loans
with an Interest Period of 3 months. Amounts repaid in respect of Loans may not
be reborrowed.

         2.02 CONTINUATIONS OF LOANS.

         (a) Except as provided in Section 3.02 or 3.03 and unless repaid or
prepaid in accordance with the provisions hereof, each Eurodollar Rate Loan
shall automatically be continued on the last day of the Interest Period in
effect with respect thereto as a Eurodollar Rate Loans for another Interest
Period. Unless otherwise specified in a timely Interest Period Notice from the
Borrower to the Administrative Agent, the length of the Interest Period of the
continued Eurodollar Rate Loan shall remain unchanged from the immediately
preceding Interest Period. Each Interest Period Notice must be received by the
Administrative Agent not later than 12:00 noon three Business Days prior to the
requested date of any continuation of Eurodollar Rate Loans. Such Interest
Period Notice may be given by telephone, but if so given, must be confirmed
promptly by delivery to the Administrative Agent of a written Interest Period
Notice, appropriately completed and signed by a Responsible Officer of the
Borrower.

         (b) Each Lender shall make the amount of its Loan available to the
Administrative Agent in immediately available funds at the Administrative
Agent's Office not later than 1:00 p.m. on the Closing Date. Upon satisfaction
of the applicable conditions set forth in Section 4.01, the Administrative Agent
shall make all funds so received on the Closing Date available to the Borrower
in like funds as received by the Administrative Agent by wire transfer of such
funds in accordance with instructions provided to (and reasonably acceptable to)
the Administrative Agent by the Borrower.

         (c) The Administrative Agent shall promptly notify the Borrower and the
Lenders of the interest rate applicable to any Interest Period for Eurodollar
Rate Loans upon determination of such interest rate. The determination of the
Eurodollar Rate by the Administrative Agent shall be conclusive in the absence
of manifest error. At any time that Base Rate Loans are outstanding, the
Administrative

                                       22
<PAGE>

Agent shall notify the Borrower and the Lenders of any change in Credit Suisse
First Boston's prime rate used in determining the Base Rate promptly following
the public announcement of such change.

         2.03 PREPAYMENTS.

         (a) The Borrower may, upon notice to the Administrative Agent, at any
time or from time to time, voluntarily prepay Loans in whole or in part without
premium (except as set forth in paragraph (d) below and in Section 3.05) or
penalty. Any prepayment of Eurodollar Rate Loans under this paragraph (a) shall
be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in
excess thereof; and any prepayment of Base Rate Loans under this paragraph (a)
shall be in a principal amount of $1,000,000 or a whole multiple of $500,000 in
excess thereof or, in each case, if less, the entire principal amount thereof
then outstanding.

         (b) In the event and on each occasion that Net Proceeds are received by
or on behalf of the Borrower or any Subsidiary in respect of any Prepayment
Event, the Borrower shall, immediately after such Net Proceeds are received,
offer to prepay Borrowings in an aggregate amount equal to such Net Proceeds;
provided, however, that notwithstanding anything to the contrary contained
herein, if total Net Proceeds received by or on behalf of the Borrower or any
Subsidiary in respect of any Prepayment Event after (i) the Closing Date or (ii)
if a prepayment offer under this Section 2.03(b) has previously been made by the
Borrower, the date of the most recent prepayment offer made by the Borrower, are
equal to an amount less than $5,000,000, the Borrower shall make such offer to
prepay Borrowings on the last day of fiscal quarter in which such Net Proceeds
are received; and, further provided, that no Lender shall be obligated to accept
any offer made under this paragraph (b);.

         (c) In the event and on each occasion that a reduction in Net Worth (or
an increase in Indebtedness secured by Liens) would result in a default or event
of default under this Agreement, the Three-Year Credit Agreement, the 364-Day
Credit Agreement or any other agreement of the Borrower absent a reduction in
the Total Outstandings, the Borrower shall, not later than the last day of the
Fiscal Quarter on which such reduction in Net Worth (or increase of Indebtedness
secured by Liens) occurs, prepay Borrowings in an aggregate amount not less than
the amount required so that such default or event of default shall not occur.

         (d) In the event and on each occasion that Loans are prepaid more than
90 days after the Closing Date under paragraph (a) or (c) above, the amount of
such prepayment shall be accompanied by a premium in an amount equal to:

                  (i) if such prepayment is made after the day that is 90 days
         after the Closing Date but on or prior to the day immediately preceding
         the first anniversary of the Closing Date, 3.00% of the aggregate
         amount of the Loans being prepaid;

                  (ii) if such prepayment is made on or after the first
         anniversary of the Closing Date but on or prior to the day immediately
         preceding the second anniversary of the Closing Date, 2.00% of the
         aggregate amount of the Loans being prepaid; and

                  (iii) if such prepayment is made on or after the second
         anniversary of the Closing Date but on or prior to the day that is
         immediately preceding the Maturity Date, 1.00% of the aggregate amount
         of the Loans being prepaid.

                                       23
<PAGE>

         (e) Prior to any voluntary or mandatory prepayment of Borrowings
hereunder, the Borrower shall select the Borrowing or Borrowings to be prepaid
and shall specify such selection in the notice of such prepayment pursuant to
paragraph (f) below.

         (f) The Borrower shall notify the Administrative Agent of any
prepayment hereunder not later than 12:00 noon (A) three Business Days prior to
any date of prepayment of Eurodollar Rate Loans and (B) on the date of
prepayment of Base Rate Loans. Each such notice shall specify the date and
amount of such prepayment and the Type(s) of Loans to be prepaid. The
Administrative Agent will promptly notify each Lender of its receipt of each
such notice, and of the amount of such Lender's Pro Rata Share of such
prepayment. If such notice is given by the Borrower, the Borrower shall make
such prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan
shall be accompanied by all accrued interest thereon, together with any
additional amounts required pursuant to Section 3.05. Each such prepayment shall
be applied to the Loans of the Lenders in accordance with their respective Pro
Rata Shares.

         2.04 TERMINATION OF COMMITMENTS.

         The Commitments shall terminate at 5:00 p.m. on the Closing Date.

         2.05 REPAYMENT OF LOANS.

         The Borrower shall repay on the Maturity Date the aggregate principal
amount of the Loans outstanding on such date. Payment shall be made to the
Administrative Agent for the account of the Lenders.

         2.06 INTEREST.

         (a) Subject to the provisions of subsection (b) below, (i) each
Eurodollar Rate Loan shall bear interest on the outstanding principal amount
thereof for each Interest Period at a rate per annum equal to the Eurodollar
Rate for such Interest Period plus the Applicable Rate; and (ii) each Base Rate
Loan shall bear interest on the outstanding principal amount thereof from the
applicable borrowing date at a rate per annum equal to the Base Rate plus the
Applicable Rate.

         (b) If any amount payable by the Borrower under any Loan Document is
not paid when due (without regard to any applicable grace periods), whether at
stated maturity, by acceleration or otherwise, such amount shall thereafter bear
interest at a fluctuating interest rate per annum at all times equal to the
Default Rate to the fullest extent permitted by applicable Laws. In addition,
while any Event of Default exists, the Borrower shall pay interest on the
principal amount of all outstanding Obligations hereunder at a fluctuating
interest rate per annum at all times equal to the Default Rate to the fullest
extent permitted by applicable Laws. Accrued and unpaid interest on past due
amounts (including interest on past due interest) shall be due and payable upon
demand.

         (c) Interest on each Loan shall be due and payable in arrears on each
Interest Payment Date applicable thereto and at such other times as may be
specified herein. Interest hereunder shall be due and payable in accordance with
the terms hereof before and after judgment, and before and after the
commencement of any proceeding under any Debtor Relief Law.

                                       24
<PAGE>

         2.07 FEES. (a) The Borrower shall pay to the Arranger and the
Administrative Agent for their own respective accounts fees in the amounts and
at the times specified in the Fee Letter. Such fees shall be fully earned when
paid and shall not be refundable for any reason whatsoever.

         (b) The Borrower shall pay to the Lenders such fees as shall have been
separately agreed upon in writing in the amounts and at the times so specified.
Such fees shall be fully earned when paid and shall not be refundable for any
reason whatsoever.

         2.08 COMPUTATION OF INTEREST AND FEES. All computations of interest for
Base Rate Loans when the Base Rate is determined by Credit Suisse First Boston's
"prime rate" shall be made on the basis of a year of 365 or 366 days, as the
case may be, and actual days elapsed. All other computations of fees and
interest shall be made on the basis of a 360-day year and actual days elapsed
(which results in more fees or interest, as applicable, being paid than if
computed on the basis of a 365-day year). Interest shall accrue on each Loan for
the day on which the Loan is made, and shall not accrue on a Loan, or any
portion thereof, for the day on which the Loan or such portion is paid, provided
that any Loan that is repaid on the same day on which it is made shall, subject
to Section 2.10(a), bear interest for one day.

         2.09 EVIDENCE OF DEBT.

         The Loans made by each Lender shall be evidenced by one or more
accounts or records maintained by such Lender and by the Administrative Agent in
the ordinary course of business. The accounts or records maintained by the
Administrative Agent and each Lender shall be conclusive absent manifest error
of the amount of the Loans made by the Lenders to the Borrower and the interest
and payments thereon. Any failure to so record or any error in doing so shall
not, however, limit or otherwise affect the obligation of the Borrower hereunder
to pay any amount owing with respect to the Obligations. In the event of any
conflict between the accounts and records maintained by any Lender and the
accounts and records of the Administrative Agent in respect of such matters, the
accounts and records of the Administrative Agent shall control in the absence of
manifest error. Upon the request of any Lender made through the Administrative
Agent, the Borrower shall execute and deliver to such Lender (through the
Administrative Agent) a Note, which shall evidence such Lender's Loans in
addition to such accounts or records. Each Lender may attach schedules to its
Note and endorse thereon the date, Type (if applicable), amount and maturity of
its Loans and payments with respect thereto.

         2.10 PAYMENTS GENERALLY.

         (a) All payments to be made by the Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.
Except as otherwise expressly provided herein, all payments by the Borrower
hereunder shall be made to the Administrative Agent, for the account of the
respective Lenders to which such payment is owed, at the Administrative Agent's
Office in Dollars and in immediately available funds not later than 2:00 p.m. on
the date specified herein. The Administrative Agent will promptly distribute to
each Lender its Pro Rata Share (or other applicable share as provided herein) of
such payment in like funds as received by wire transfer to such Lender's Lending
Office. All payments received by the Administrative Agent after 2:00 p.m. shall
be deemed received on the next succeeding Business Day and any applicable
interest or fee shall continue to accrue.

         (b) If any payment to be made by the Borrower shall come due on a day
other than a Business Day, payment shall be made on the next following Business
Day, and such extension of time shall be reflected in computing interest or
fees, as the case may be.

                                       25
<PAGE>

         (c) Unless the Borrower or any Lender has notified the Administrative
Agent, prior to the date any payment is required to be made by it to the
Administrative Agent hereunder, that the Borrower or such Lender, as the case
may be, will not make such payment, the Administrative Agent may assume that the
Borrower or such Lender, as the case may be, has timely made such payment and
may (but shall not be so required to), in reliance thereon, make available a
corresponding amount to the Person entitled thereto. If and to the extent that
such payment was not in fact made to the Administrative Agent in immediately
available funds, then:

                  (i) if the Borrower failed to make such payment, each Lender
         shall forthwith on demand repay to the Administrative Agent the portion
         of such assumed payment that was made available to such Lender in
         immediately available funds, together with interest thereon in respect
         of each day from and including the date such amount was made available
         by the Administrative Agent to such Lender to the date such amount is
         repaid to the Administrative Agent in immediately available funds at
         the Federal Funds Rate from time to time in effect; and

                  (ii) if any Lender failed to make such payment, such Lender
         shall forthwith on demand pay to the Administrative Agent the amount
         thereof in immediately available funds, together with interest thereon
         for the period from the date such amount was made available by the
         Administrative Agent to the Borrower to the date such amount is
         recovered by the Administrative Agent (the "Compensation Period") at a
         rate per annum equal to the Federal Funds Rate from time to time in
         effect. If such Lender pays such amount to the Administrative Agent,
         then such amount shall constitute such Lender's Loan included in the
         applicable Borrowing. If such Lender does not pay such amount forthwith
         upon the Administrative Agent's demand therefor, the Administrative
         Agent may make a demand therefor upon the Borrower, and the Borrower
         shall pay such amount to the Administrative Agent, together with
         interest thereon for the Compensation Period at a rate per annum equal
         to the rate of interest applicable to the applicable Borrowing. Nothing
         herein shall be deemed to relieve any Lender from its obligation to
         fulfill its Commitment or to prejudice any rights which the
         Administrative Agent or the Borrower may have against any Lender as a
         result of any default by such Lender hereunder.

         A notice of the Administrative Agent to any Lender or the Borrower with
respect to any amount owing under this subsection (c) shall be conclusive,
absent manifest error.

         (d) If any Lender makes available to the Administrative Agent funds for
any Loan to be made by such Lender as provided in the foregoing provisions of
this Article II, and such funds are not made available to the Borrower by the
Administrative Agent because the conditions to the applicable Borrowing set
forth in Article IV are not satisfied or waived in accordance with the terms
hereof, the Administrative Agent shall return such funds (in like funds as
received from such Lender) to such Lender, without interest.

         (e) The obligations of the Lenders hereunder to make Loans are several
and not joint. The failure of any Lender to make any Loan or to fund any such
participation on any date required hereunder shall not relieve any other Lender
of its corresponding obligation to do so on such date, and no Lender shall be
responsible for the failure of any other Lender to so make its Loan or purchase
its participation.

         (f) Nothing herein shall be deemed to obligate any Lender to obtain the
funds for any Loan in any particular place or manner or to constitute a
representation by any Lender that it has obtained or will obtain the funds for
any Loan in any particular place or manner.

                                       26
<PAGE>

         2.11 SHARING OF PAYMENTS. If, other than as expressly provided
elsewhere herein, any Lender shall obtain on account of the Loans made by it,
any payment (whether voluntary, involuntary, through the exercise of any right
of set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder) thereof, such Lender shall immediately (a) notify the
Administrative Agent of such fact, and (b) purchase from the other Lenders such
participations in the Loans made by them as shall be necessary to cause such
purchasing Lender to share the excess payment in respect of such Loans or such
participations, as the case may be, pro rata with each of them; provided,
however, that if all or any portion of such excess payment is thereafter
recovered from the purchasing Lender under any of the circumstances described in
Section 10.06 (including pursuant to any settlement entered into by the
purchasing Lender in its discretion), such purchase shall to that extent be
rescinded and each other Lender shall repay to the purchasing Lender the
purchase price paid therefor, together with an amount equal to such paying
Lender's ratable share (according to the proportion of (i) the amount of such
paying 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, without further
interest thereon. The Borrower agrees that any Lender so purchasing a
participation from another Lender may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 10.09) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation.
The Administrative Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Lenders following any such purchases or
repayments. Each Lender that purchases a participation pursuant to this Section
shall from and after such purchase have the right to give all notices, requests,
demands, directions and other communications under this Agreement with respect
to the portion of the Obligations purchased to the same extent as though the
purchasing Lender were the original owner of the Obligations purchased.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.01 TAXES.

         (a) Any and all payments by the Borrower to or for the account of the
Administrative Agent or any Lender under any Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of the
Administrative Agent and each Lender, taxes imposed on or measured by its
overall net income, and franchise taxes imposed on it (in lieu of net income
taxes), by the jurisdiction (or any political subdivision thereof) under the
Laws of which the Administrative Agent or such Lender, as the case may be, is
organized or maintains a lending office (all such non-excluded taxes, duties,
levies, imposts, deductions, assessments, fees, withholdings or similar charges,
and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall
be required by any Laws to deduct any Taxes from or in respect of any sum
payable under any Loan Document to the Administrative Agent or any Lender, (i)
the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section), each of the Administrative Agent and such Lender receives
an amount equal to the sum it would have received had no such deductions been
made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay
the full amount deducted to the relevant taxation authority or other authority
in accordance with applicable Laws, and (iv) within 30 days after the date of
such payment, the Borrower shall furnish to the Administrative Agent (which
shall forward the same to such Lender) the original or a certified copy of a
receipt evidencing payment thereof.

                                       27
<PAGE>

         (b) In addition, the Borrower agrees to pay any and all present or
future stamp, court or documentary taxes and any other excise or property taxes
or charges or similar levies which arise from any payment made under any Loan
Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "Other Taxes").

         (c) If the Borrower shall be required to deduct or pay any Taxes or
Other Taxes from or in respect of any sum payable under any Loan Document to the
Administrative Agent or any Lender, the Borrower shall also pay to the
Administrative Agent or to such Lender, as the case may be, at the time interest
is paid, such additional amount that the Administrative Agent or such Lender
specifies is necessary to preserve the after-tax yield (after factoring in all
taxes, including taxes imposed on or measured by net income) that the
Administrative Agent or such Lender would have received if such Taxes or Other
Taxes had not been imposed.

         (d) The Borrower agrees to indemnify the Administrative Agent and each
Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section) paid by the Administrative Agent and such Lender, (ii) amounts
payable under Section 3.01(c) and (iii) any liability (including additions to
tax, penalties, interest and expenses) arising therefrom or with respect
thereto, in each case whether or not such Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. Payment
under this subsection (d) shall be made within 30 days after the date the Lender
or the Administrative Agent makes a demand therefor.

         3.02 ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for any Lender or its applicable Lending Office to make, maintain or fund
Eurodollar Rate Loans, or to determine or charge interest rates based upon the
Eurodollar Rate, then, on notice thereof by such Lender to the Borrower through
the Administrative Agent, any obligation of such Lender to make or continue
Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans
shall be suspended until such Lender notifies the Administrative Agent and the
Borrower that the circumstances giving rise to such determination no longer
exist. Upon receipt of such notice, the Borrower shall, upon demand from such
Lender (with a copy to the Administrative Agent), prepay or, if applicable,
convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on
the last day of the Interest Period therefor, if such Lender may lawfully
continue to maintain such Eurodollar Rate Loans to such day, or immediately, if
such Lender may not lawfully continue to maintain such Eurodollar Rate Loans.
Upon any such prepayment or conversion, the Borrower shall also pay accrued
interest on the amount so prepaid or converted. Each Lender agrees to designate
a different Lending Office if such designation will avoid the need for such
notice and will not, in the good faith judgment of such Lender, otherwise be
materially disadvantageous to such Lender.

         3.03 INABILITY TO DETERMINE RATES. If the Required Lenders determine
that for any reason adequate and reasonable means do not exist for determining
the Eurodollar Rate for any requested Interest Period with respect to a proposed
Eurodollar Rate Loan, or that the Eurodollar Rate for any requested Interest
Period with respect to a proposed Eurodollar Rate Loan does not adequately and
fairly reflect the cost to such Lenders of funding such Loan, the Administrative
Agent will promptly so notify the Borrower and each Lender. Thereafter, the
obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be
suspended until the Administrative Agent (upon the instruction of the Required
Lenders) revokes such notice. Upon receipt of such notice, the Borrower may
revoke any pending request for a conversion to or continuation of Eurodollar
Rate Loans or, failing that, will be deemed to have converted such request into
a request for a Borrowing of Base Rate Loans in the amount specified therein.

                                       28
<PAGE>

         3.04 INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY; RESERVES ON
EURODOLLAR RATE LOANS.

         (a) If any Lender determines that as a result of the introduction of or
any change in or in the interpretation of any Law, or such Lender's compliance
therewith, there shall be any increase in the cost to such Lender of agreeing to
make or making, funding or maintaining Eurodollar Rate Loans or a reduction in
the amount received or receivable by such Lender in connection with any of the
foregoing (excluding for purposes of this subsection (a) any such increased
costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to
which Section 3.01 shall govern), (ii) changes in the basis of taxation of
overall net income or overall gross income by the United States or any foreign
jurisdiction or any political subdivision of either thereof under the Laws of
which such Lender is organized or has its Lending Office, and (iii) reserve
requirements contemplated by Section 3.04(c)), then from time to time upon
demand of such Lender (with a copy of such demand to the Administrative Agent),
the Borrower shall pay to such Lender such additional amounts as will compensate
such Lender for such increased cost or reduction.

         (b) If any Lender determines that the introduction of any Law regarding
capital adequacy or any change therein or in the interpretation thereof, or
compliance by such Lender (or its Lending Office) therewith, has the effect of
reducing the rate of return on the capital of such Lender or any corporation
controlling such Lender as a consequence of such Lender's obligations hereunder
(taking into consideration its policies with respect to capital adequacy and
such Lender's desired return on capital), then from time to time upon demand of
such Lender (with a copy of such demand to the Administrative Agent), the
Borrower shall pay to such Lender such additional amounts as will compensate
such Lender for such reduction.

         (c) The Borrower shall pay to each Lender, as long as such Lender shall
be required to maintain reserves with respect to liabilities or assets
consisting of or including Eurocurrency funds or deposits (currently known as
"Eurocurrency liabilities"), additional interest on the unpaid principal amount
of each Eurodollar Rate Loan equal to the actual costs of such reserves
allocated to such Loan by such Lender (as determined by such Lender in good
faith, which determination shall be conclusive), which shall be due and payable
on each date on which interest is payable on such Loan, provided the Borrower
shall have received at least 15 days' prior notice (with a copy to the
Administrative Agent) of such additional interest from such Lender. If a Lender
fails to give notice 15 days prior to the relevant Interest Payment Date, such
additional interest shall be due and payable 15 days from receipt of such
notice. The Borrower shall not be required to compensate a Lender pursuant to
this subsection (c) for any additional costs incurred more than 180 days prior
to the date that such Lender gives notice to the Borrower of additional costs
and of the Lender's intention to claim compensation therefor; provided, that if
the change in law or regulations giving rise to such costs is retroactive, then
the 180-day period shall be extended to include the period of retroactive effect
thereof.

         3.05 FUNDING LOSSES. Upon demand of any Lender (with a copy to the
Administrative Agent) from time to time, the Borrower shall promptly compensate
such Lender for and hold such Lender harmless from any loss, cost or expense
incurred by it as a result of:

         (a) any continuation, conversion, payment or prepayment of any Loan
other than a Base Rate Loan on a day other than the last day of the Interest
Period for such Loan (whether voluntary, mandatory, automatic, by reason of
acceleration, or otherwise);

                                       29
<PAGE>

         (b) any failure by the Borrower (for a reason other than the failure of
such Lender to make a Loan) to prepay, borrow, continue or convert any Loan
other than a Base Rate Loan on the date or in the amount notified by the
Borrower; or

         (c) any assignment of a Eurodollar Rate Loan on a day other than the
last day of the Interest Period therefor as a result of a request by the
Borrower pursuant to Section 10.16;

including any loss of anticipated profits and any loss or expense arising from
the liquidation or reemployment of funds obtained by it to maintain such Loan or
from fees payable to terminate the deposits from which such funds were obtained.
The Borrower shall also pay any customary administrative fees charged by such
Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Borrower to the Lenders under
this Section 3.05, each Lender shall be deemed to have funded each Eurodollar
Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit
or other borrowing in the London interbank eurodollar market for a comparable
amount and for a comparable period, whether or not such Eurodollar Rate Loan was
in fact so funded.

         3.06 MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION.

         (a) A certificate of the Administrative Agent or any Lender claiming
compensation under this Article III and setting forth the additional amount or
amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, the Administrative Agent or such
Lender may use any reasonable averaging and attribution methods.

         (b) Upon any Lender's making a claim for compensation under Section
3.01 or 3.04, the Borrower may replace such Lender in accordance with Section
10.16.

         (c) Upon any Lender's making a determination that it is unlawful to
maintain Eurodollar Rate Loans and such Lender fails to designate a different
Lending Office pursuant to Section 3.02, the Borrower may replace such Lender in
accordance with Section 10.16.

         3.07 SURVIVAL. All of the Borrower's obligations under this Article III
shall survive termination of the Aggregate Commitments and repayment of all the
Loans and other Obligations hereunder; provided, that with respect to amounts
payable under Sections 3.04 and 3.05, such amounts shall be deemed to have been
paid if no claim therefor is made within two years after the date that all Loans
have been paid in full and all commitments to make Loans hereunder have
terminated.

                                   ARTICLE IV.

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Administrative Agent and
each Lender that:

         5.01 CORPORATE EXISTENCE; POWER; COMPLIANCE WITH LAWS.

         (a) the Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware, and each
Subsidiary of the Borrower is a corporation, partnership, or limited liability
company, as the case may be, duly incorporated or otherwise formed, validly
existing and in good standing under the laws of the state of its incorporation
or formation;

         (b) the Borrower and each other Loan Party has all requisite corporate
power and authority, governmental licenses, authorizations, consents and
approvals to own its assets, carry on its business as currently conducted, to
execute, deliver, and perform its obligations under the Loan Documents, and, in
the case of the Borrower, to issue the Notes in the manner and for the purpose
contemplated by this Agreement, and each Subsidiary, has all requisite
corporate, partnership or limited liability company, as the case may be, power
and authority to own its assets and to carry on the business in which it is
engaged;

         (c) the Borrower and each Subsidiary of the Borrower is duly qualified
as a foreign Person authorized to do business and is licensed and in good
standing under the laws of each jurisdiction where its ownership, lease or
operation of property or the conduct of its business requires such qualification
or license other than where the failure to be so qualified or in good standing
would not reasonably be expected to have a Material Adverse Effect; and

         (d) the Borrower and each of its Subsidiaries is in compliance in all
material respects with all Requirements of Law, except to the extent that the
failure to do so would not reasonably be expected to have a Material Adverse
Effect.

         5.02 CORPORATE AUTHORIZATION; NO CONTRAVENTION. The execution, delivery
and performance by the Borrower and each other Loan Party of the Loan Documents
to which it is party have been duly authorized by all necessary corporate
action, and do not and will not:

         (a) contravene the terms of any of its Organization Documents;

         (b) result in any breach or contravention of, or result in the creation
of any Lien (other than Liens created by the Loan Documents) under, any document
evidencing any Contractual Obligation to which it is a party or any order,
injunction, writ or decree of any Governmental Authority to which it or its
property is subject (other than such violations, breaches, defaults or Liens
which would not reasonably be expected to have a Material Adverse Effect); or

         (c) violate any Requirement of Law.

         5.03 GOVERNMENTAL AUTHORIZATION; OTHER CONSENTS. No approval, consent,
exemption, authorization, or other action by, or notice to, or filing with, any
Governmental Authority or other Person is necessary for the validity of the
execution, delivery or performance by, or enforcement against, the Borrower or
any other Loan Party of this Agreement, any Note or any other Loan Document
other than routine informational filings with the SEC and/or other Governmental
Authorities.

                                       33
<PAGE>

         5.04 BINDING EFFECT. This Agreement and (when executed and delivered
for value) each other Loan Document constitute the legal, valid and binding
obligations of the Borrower and each other Loan Party party thereto, enforceable
against each of them in accordance with their respective terms, except as
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting the enforcement of creditors' rights generally or
by equitable principles relating to enforceability (whether considered in a
court of law or a proceeding in equity).

         5.05 LITIGATION. No litigation (including derivative actions),
arbitration proceedings or governmental proceedings are pending or, to the best
knowledge of the Borrower after due inquiry, overtly threatened against the
Borrower or any Subsidiary (a) which would reasonably be expected to result in a
Material Adverse Effect, or (b) that question the validity or enforceability of
this Agreement, any other Loan Document or the transactions contemplated hereby
or thereby. Neither the Borrower nor any of its Subsidiaries has knowledge of
any material contingent liabilities, including those disclosed in the financial
statements referred to in Section 5.13, which would reasonably be expected to
have a Material Adverse Effect.

         5.06 NO DEFAULT. No Default or Event of Default exists. Neither the
Borrower nor any Subsidiary is in default under or with respect to its
Organization Documents in any respect which, individually or together with all
other such defaults, would reasonably be expected to have a Material Adverse
Effect.

         5.07 FIRE, STRIKE, ACT OF GOD, ETC. Neither the business nor the
properties of the Borrower or any of its Subsidiaries are now affected by any
fire, explosion, accident, labor controversy, strike, lockout or other dispute,
drought, storm, hail, earthquake, embargo, act of God or of the public enemy or
other casualty which would reasonably be expected to have a Material Adverse
Effect, or if any such existing event or condition were to continue for more
than 30 additional days (unless in the reasonable opinion of the Borrower such
event or condition is not likely to continue for such period) would reasonably
be expected to have a Material Adverse Effect.

         5.08 LIENS. None of the assets or properties of the Borrower or the
Subsidiaries is subject to any Lien except for Permitted Liens and there are no
Permitted Liens of the Borrower existing in reliance on Section 7.01(a)(xix).

         5.09 ERISA. Each Plan and, to the best of the Borrower's knowledge,
each Multiemployer Plan, complies in all material respects with all Requirements
of Law except to the extent that noncompliance could not reasonably be expected
to have a Material Adverse Effect and,

         (a) no Reportable Event for which the PBGC has not waived the 30-day
notice requirement has occurred with respect to any Plan or, to the best of the
Borrower's knowledge, any Multiemployer Plan, which could result in the Borrower
incurring a liability or obligation in excess of $10,000,000;

         (b) no steps have been taken to terminate any Plan which could result
in the Borrower's making a contribution, or incurring a liability or obligation,
to such Plan in excess of $10,000,000; no steps have been taken to appoint a
receiver to administer any such Plan; to the best of the Borrower's knowledge,
no steps have been taken to terminate or appoint a receiver to administer any
Multiemployer Plan which could result in the Borrower's making a contribution,
or incurring a liability or obligation, to such Multiemployer Plan in excess of
$10,000,000; and neither the Borrower nor any Related Person has withdrawn from
any such Multiemployer Plan or initiated steps to do so;

                                       34
<PAGE>

         (c) there is no Unfunded Vested Liability with respect to any Plan or,
to the best of the Borrower's knowledge, any Multiemployer Plan, that would
reasonably be expected to have, in the event of termination of such Plan or
withdrawal from such Multiemployer Plan, a Material Adverse Effect; and

         (d) no contribution failure has occurred with respect to any Plan
sufficient to give rise to a Lien under Section 302(f) of ERISA; no condition
exists or event or transaction has occurred with respect to any Plan which would
reasonably be expected to have a Material Adverse Effect; and neither the
Borrower nor any of its Subsidiaries has any contingent liability with respect
to any post-retirement benefit under a Welfare Plan, other than liability for
continuation coverage described in Part 5 of Title I of ERISA, that would
reasonably be expected to have a Material Adverse Effect.

         5.10 USE OF PROCEEDS; MARGIN REGULATIONS. The proceeds of the Loans are
to be used solely for purposes not in contravention of subsection 7.01(i) or
subsection 7.01(k). Not more than 25% of the assets of the Borrower and its
Subsidiaries on a consolidated basis consists of any Margin Stock, and no part
of the proceeds of any Loan will be used to buy or carry any Margin Stock.
Neither the Borrower nor any Subsidiary is generally engaged in the business of
buying or selling Margin Stock or extending credit for the purpose of buying or
carrying Margin Stock.

         5.11 TITLE TO PROPERTIES. The Borrower and each of its Subsidiaries (i)
has valid fee title to, or valid leasehold interests in, all of its respective
material real property, and has good and valid title to all of its respective
material personal properties and assets, of any nature whatsoever which are
reflected on the audited balance sheet referred to in Section 5.13 or acquired
by the Borrower or such Subsidiary after the date thereof except for assets
sold, transferred or otherwise disposed of since such date in the ordinary
course of business, except for such defects in title as would not, individually
or in the aggregate, be reasonably expected to have a Material Adverse Effect
and (ii) owns or holds all permits necessary to construct, own, operate, use and
maintain its respective property and assets and to conduct its respective
business as now conducted except where the failure to have such interest or
title or to own or hold such permit would not reasonably be expected to have a
Material Adverse Effect.

         5.12 TAXES. The Borrower and each Subsidiary has filed (or obtained
extensions with respect to the filing of) all United States federal income tax
returns and all other material tax returns which are required to be filed by it
and has paid all taxes as shown on such returns or pursuant to any assessment
received by the Borrower or any Subsidiary, except to the extent the same may be
contested in good faith and for which reserves have been established to the
extent required by GAAP. The charges, accruals and reserves on the books of the
Borrower and each Subsidiary in respect of Taxes and other governmental charges
are adequate to the best knowledge of the Borrower.

         5.13 FINANCIAL CONDITION.

         (a) The audited consolidated balance sheet of the Borrower and its
consolidated Subsidiaries as of December 31, 2002, and the related consolidated
statements of income or operations, shareholder's equity and cash flows for the
fiscal year ended on that date (i) were prepared in accordance with GAAP
consistently applied throughout the period covered thereby, except as otherwise
expressly noted therein; and (ii) fairly present the financial position of the
Borrower and its consolidated Subsidiaries as of the date thereof and results of
operations for the period covered thereby.

         (b) All Off-Balance Sheet Liabilities of the Borrower and its
Subsidiaries are accurately set forth (a) as of the Closing Date, on Schedule
5.13(c) and (b) as of the end of each Fiscal Year beginning with the Fiscal Year
ended December 31, 2003, on an updated Schedule attached to the Compliance

                                       35
<PAGE>

Certificate delivered by the Borrower with the most recent annual financial
statements delivered pursuant to Section 6.01(a).

         (c) Since December 31, 2002, no event or condition has occurred which,
either individually or in the aggregate, has had or could reasonably be expected
to have a Material Adverse Effect, except as disclosed on Schedule 5.13(d).

         5.14 ENVIRONMENTAL MATTERS. Each of the Borrower and its Subsidiaries
are in compliance in all material respects with all Federal, state and local
laws and regulations (i) now applicable to it, or (ii) which, to the best
knowledge of the Borrower will be applicable (or, if not in compliance with such
laws and regulations referred to in this clause (ii), the Borrower or such
Subsidiary is taking appropriate action diligently pursued to be in compliance
therewith on a timely basis or to be exempt from compliance) to it relating to
pollution control and environmental contamination, including all laws and
regulations governing the generation, use, collection, treatment, storage,
transportation, recovery, removal, discharge or disposal of Hazardous Materials,
except to the extent that the failure to comply or take such action would not
reasonably be expected to have a Material Adverse Effect. Except as disclosed on
Schedule 5.14 (as updated from time to time), (A) there are no presently
outstanding allegations by governmental officials that the Borrower or any of
its Subsidiaries is now or at any time prior to the date hereof, was in material
violation of such laws or regulations, (B) there are no material administrative
or judicial proceedings presently pending against the Borrower or any of its
Subsidiaries pursuant to such laws or regulations, and (C) there is no material
claim presently outstanding against the Borrower or any of its Subsidiaries
which was asserted pursuant to such laws or regulations that in each case would
reasonably be expected to result in a liability to the Borrower or any
Subsidiary in excess of $20,000,000 or $50,000,000 in the aggregate for all such
claims (net in each case of actual insurance coverage or effective
indemnification with respect thereto). Except as disclosed in Schedule 5.14 (as
updated from time to time), the Borrower reasonably believes that no facts or
circumstances known to it or any Subsidiary could form the basis for the
assertion of any material claim against the Borrower or any Subsidiary relating
to environmental matters, including any material claim arising from past or
present environmental practices asserted under CERCLA, RCRA, or any
Environmental Law that in each case would reasonably be expected to result in a
liability to the Borrower or any Subsidiary in excess of $20,000,000 or
$50,000,000 in the aggregate for all such claims (net in each case of actual
insurance coverage or effective indemnification with respect thereto).

         5.15 REGULATED ENTITIES. None of the Borrower, any Person controlling
the Borrower, or any Subsidiary, is an "Investment Company" within the meaning
of the Investment Company Act of 1940. Neither the Borrower nor any Loan Party
is subject to regulation under the Public Utility Holding Company Act of 1935,
the Federal Power Act, the Interstate Commerce Act or any state public utilities
code.

         5.16 COPYRIGHTS, PATENTS, TRADEMARKS AND LICENSES, ETC. The Borrower or
its Subsidiaries own or are licensed or otherwise have the right to use all of
the patents, trademarks, trade names, copyrights, contractual franchises,
authorizations and other rights that are reasonably necessary for the operation
of their respective businesses as currently conducted (other than where the
failure to so own, be licensed or have the right to use would reasonably be
expected to have a Material Adverse Effect). To the best knowledge of the
Borrower, no slogan or other advertising device, product process, method,
substance, part or other material now employed, or now contemplated to be
employed, by the Borrower or any Subsidiary infringes upon any rights held by
any other Person, except for any such infringement that would not reasonably be
expected to have a Material Adverse Effect.

                                       36

financial ratios and restrictions contained in Section 7.02 and affirmatively
indicating that, while the audit of the consolidated financial statements of the
Borrower and its consolidated Subsidiaries was not directed primarily toward
obtaining knowledge of such compliance with these specific financial ratios and

result in the requirement that the Borrower furnish a bond or other

                                       39
<PAGE>

security to the PBGC or such Plan, or the occurrence of any event with respect

         6.04 PRESERVATION OF CORPORATE EXISTENCE, ETC. The Borrower shall, and
shall cause each Subsidiary to, except for any sale, dissolution, liquidation or
merger not otherwise prohibited hereby, preserve and maintain its existence and
good standing and its rights, privileges and franchises under the laws of its
state or jurisdiction of incorporation or other formation, and remain qualified
as a foreign Person authorized to do business in each other jurisdiction in
which the failure to so qualify would reasonably be expected to have a Material
Adverse Effect.

Subsidiary to maintain, insurance with respect to their respective properties
and businesses against such liabilities, casualties, risks and contingencies
(including business interruption insurance) in such types and with such
reasonable deductibles and in such amounts (after giving effect to any
self-insurance compatible with the following standards) as are customary in the
case of Persons engaged in the same or similar businesses and similarly
situated. The Borrower and its Subsidiaries shall maintain such insurance (i)
with financially sound and reputable insurers that are not Affiliates of the
Borrower (it is agreed that Oil Insurance Limited and sEnergy Insurance Ltd.
shall not be considered Affiliates of the Borrower for purposes of this Section
6.05), or (ii) with Affiliates(s) ("Affiliated Insurers") to the extent as is

shall provide that (A) the interests and rights held by such Affiliated Insurers
vis-a-vis the Unaffiliated Insurers shall pass through to the Borrower (or its
Subsidiary as applicable), and such interests and rights of the Borrower (or its
Subsidiary as applicable) vis-a-vis the Unaffiliated Insurers shall not be
invalidated or impaired by any act or neglect of, or any bankruptcy, insolvency,
dissolution or other event with respect to, the Affiliated Insurers, and (B) in
the event of the insolvency, dissolution or financial impairment of the
Affiliated Insurers that adversely affects the Borrower's (or its Subsidiary's)
ability to enforce such interests and rights against and receive payment from
the Affiliated Insurer(s), such payment will be payable by the Unaffiliated
Insurers directly to the Borrower (or its Subsidiary as applicable) under the
same circumstances and in the same amounts as would have been available to the
Borrower but for the Affiliated Insurer's insolvency, dissolution or financial
impairment. With respect to the Borrower and its Subsidiaries, the Affiliated
Insurers shall not retain any risk that is not covered by such agreements with
Unaffiliated Insurers.

         (b) Upon the execution of this Agreement and at any time thereafter at
the request of the Administrative Agent, the Borrower shall furnish or cause to
be furnished to the Administrative Agent evidence, in form and substance

appropriate proceedings and so long as reserves have been established to the
extent required by GAAP.

         6.07 COMPLIANCE WITH LAWS. The Borrower shall comply, and shall cause
each Subsidiary to comply, in all material respects with all Requirements of

as the validity or application thereof is being contested in good faith and
reserves have been established with respect to such contest to the extent, if
any, required by GAAP or where such non-compliance would not reasonably be
expected to have a Material Adverse Effect, and obtain and maintain, and cause
each Subsidiary to obtain and maintain, all permits, licenses and approvals
necessary to construct, own, operate, use and maintain their respective
properties and assets and to conduct their respective businesses, except where
the failure to obtain or maintain such permit, license or approval would not

shall keep or cause to be kept, and shall cause each Subsidiary to keep or cause
to be kept, adequate records and book of account in which complete entries are
to be made reflecting its business and financial transactions and as required by

officers, all at such reasonable times during normal business hours and as often
as may be reasonably desired, upon prior notice to the Borrower of at least 24
hours in advance; provided, however, that when an Event of Default exists the
Administrative Agent or any Lender may take the actions specified in this
sentence at any times during normal business hours and without advance notice.

the Administrative Agent or a Lender or their respective representatives when
making any visit or inspection described in the preceding sentence.

         (b) Neither the Administrative Agent nor any Lender has any duty to
visit or inspect the Borrower's or any Subsidiary's properties or to examine or
copy such records and neither the Administrative Agent nor any Lender shall
incur any obligation or liability by reason of not making any such visit or
inspection. In the event that the Administrative Agent or any Lender shall do
any of the foregoing, it will be acting solely for the purposes of protecting
the Administrative Agent or such Lender and preserving its rights under this
Agreement. Neither the Borrower nor any other party is entitled to rely on any
inspection or other inquiry by the Administrative Agent or any Lender. Neither
the Administrative Agent nor any Lender owes any duty of care to protect the
Borrower or any other party against, or to inform the Borrower or any other
party of, any adverse condition that may be observed as

                                       41
<PAGE>

affecting the Borrower's or any Subsidiary's properties or business. The

of its Subsidiaries to, keep and maintain all property material to the conduct
of its business in good working order and condition, ordinary wear and tear
excepted.

Borrowings for working capital, capital expenditures, and other lawful general
corporate purposes not in contravention of Sections 7.01(i) or (k), any Law or
of any Loan Document.

         6.12 FURTHER ASSURANCES. The Borrower will, and will cause each other
Loan Party to, execute any and all further documents, financing statements,
agreements and instruments, and take all such further actions (including the
filing and recording of financing statements and other documents), which may be
required under any applicable law, or which the Administrative Agent or the
Required Lenders may reasonably request, to cause the Guarantee and Collateral
Requirement to be and remain satisfied at all times, all at the expense of the
Loan Parties. The Borrower also agrees to provide to the Administrative Agent,
from time to time upon request, evidence reasonably satisfactory to the
Administrative Agent as to the perfection and priority of the Liens created or
intended to be created by the Security Documents.

         Sale Leaseback Transactions providing for the sale of other assets and
         the leaseback of such assets to the Borrower or any Subsidiary,

                  (m) Restrictive Agreements. The Borrower shall not, and shall
         not permit any Subsidiary to, enter into any Contractual Obligation
         (other than this Agreement or any other Loan Document) that limits the
         ability of any Subsidiary to pay dividends or make other distributions
         to, or to repay loans or advances to, the Borrower, or to transfer
         property to the Borrower; provided, however, that this clause (m) shall
         not prohibit (i) any negative pledge incurred or provided in favor of
         any holder of Liens permitted under Section 7.01(a)(iii) or (iv) solely
         to the extent any such negative pledge relates to the property secured
         by such Liens, (ii) limitations on Project Financing/Special Purpose

         sufficient to give rise to a Lien under Section 302(f) of ERISA; or

                  (i) Material Judgments. (i) One or more non-interlocutory
         judgments (including judgments entered on arbitration awards) is
         entered against the Borrower or any Subsidiary involving in the
         aggregate liability (to the extent not covered by independent
         third-party insurance as to which the insurer does not dispute coverage
         or effective indemnification by a third party acceptable to the
         Required Lenders) exceeding $35,000,000, or (ii) any one or more
         non-monetary non-interlocutory judgments that have, or could reasonably
         be expected to have, individually or in the aggregate, a Material
         Adverse Effect, and, in the case of clause (i) or (ii), the same shall
         not have been discharged or execution thereof stayed pending appeal for
         a period of 30 days after the entry thereof, or if after the expiration
         of any such stay, any writ or warrant of attachment is levied in
         respect of such judgment or any creditor commences enforcement
         proceedings, or within 60 days after the expiration of any such stay
         such judgment shall not have been discharged; or

                  (j) Invalidity of Loan Documents or Liens under the Security
         Documents. Any Loan Document, at any time after its execution and
         delivery and for any reason other than as expressly permitted hereunder
         or satisfaction in full of all the Obligations, ceases to be in full
         force and effect; or the Borrower or any other Person contests the
         validity or enforceability of any Loan Document; or the Borrower denies
         that it has any or further liability or obligation under any Loan
         Document, or takes action to revoke, terminate or rescind any Loan
         Document, or any Lien purported to be created under any Security
         Document shall cease to be or shall be asserted by any Loan Party not
         to be, a valid and perfected Lien on any Collateral, with the priority
         required by the applicable Security Document or either Pledged Entity
         shall (except as a result of a transaction expressly permitted under
         Section 3.03(II)(b)(i) of the Guarantee and Collateral Agreement) at
         any time fail to own any equity interest set forth on Schedule 5.19 as
         being owned by it or the Borrower shall (except as a result of a
         transaction expressly permitted under Section 3.03(II)(b)(i) of the
         Guarantee and Collateral Agreement) own directly or indirectly any
         equity interest in a Colonial Pipeline Entity or in the Explorer
         Pipeline Entity that is not owned directly by a Pledged Entity; or

                  (k) Change of Control. There occurs any Change of Control,
         unless prior written consent for such lesser percentage ownership is
         obtained from the Required Lenders; or

                  (l) Other Material Obligations. Default in the payment when
         due, or in the performance or observance of, any material obligation
         of, or condition agreed to by, the Borrower or any Subsidiary with
         respect to any material purchase or lease of goods or services (except
         only to the extent that the existence of any such default is being
         contested by the Borrower or such Subsidiary in good faith and by
         appropriate proceedings) if such default would reasonably be expected
         to have a Material Adverse Effect; or

                                       53
<PAGE>

                  (m) Default of Three-Year Credit Agreement or 364-Day Credit
         Agreement. Any Event of Default shall occur and be continuing pursuant
         to the Three-Year Credit Agreement or the 364-Day Credit Agreement.

         8.02 REMEDIES UPON EVENT OF DEFAULT. If any Event of Default occurs and
is continuing, the Administrative Agent shall, at the request of, or may, with
the consent of, the Required Lenders, take any or all of the following actions:

                  (a) declare the commitment of each Lender to make Loans to be
         terminated, whereupon such commitments and obligation shall be
         terminated;

                  (b) declare the unpaid principal amount of all outstanding
         Loans, all interest accrued and unpaid thereon, and all other amounts
         owing or payable hereunder or under any other Loan Document to be
         immediately due and payable, without presentment, demand, protest or
         other notice of any kind, all of which are hereby expressly waived by
         the Borrower; and

                  (c) exercise on behalf of itself and the Lenders all rights
         and remedies available to it and the Lenders under the Loan Documents
         or applicable law;

provided, however, that upon the occurrence of an actual or deemed entry of an
order for relief with respect to the Borrower under the Bankruptcy Code of the
United States, the obligation of each Lender to make Loans shall automatically
terminate, the unpaid principal amount of all outstanding Loans and all interest
and other amounts as aforesaid shall automatically become due and payable, in
each case without further act of the Administrative Agent or any Lender.

         8.03 APPLICATION OF FUNDS. After the exercise of remedies provided for
in Section 8.02 (or after the Loans have automatically become immediately due
and payable as set forth in the proviso to Section 8.02), any amounts received
on account of the Obligations shall be applied by the Administrative Agent in
the following order:

         First, to payment of that portion of the Obligations constituting fees,
indemnities, expenses and other amounts (including Attorney Costs and amounts
payable under Article III) payable to the Administrative Agent in its capacity
as such;

         Second, to payment of that portion of the Obligations constituting
fees, indemnities and other amounts (other than principal and interest) payable
to the Lenders (including Attorney Costs and amounts payable under Article III),
ratably among them in proportion to the amounts described in this clause Second
payable to them;

         Third, to payment of that portion of the Obligations constituting
accrued and unpaid interest on the Loans, ratably among the Lenders in
proportion to the respective amounts described in this clause Third payable to
them;

         Fourth, to payment of that portion of the Obligations constituting
unpaid principal of the Loans, ratably among the Lenders in proportion to the
respective amounts described in this clause Fourth held by them; and

         Last, the balance, if any, after all of the Obligations have been
indefeasibly paid in full, to the Borrower or as otherwise required by Law.

                                   ARTICLE IX.
                              ADMINISTRATIVE AGENT

         9.01 APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT.

         Each Lender hereby irrevocably appoints, designates and authorizes the
Administrative Agent to take such action on its behalf under the provisions of
this Agreement and each other Loan Document and to exercise such powers and
perform such duties as are expressly delegated to it by the terms of this
Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Administrative
Agent shall not have any duties or responsibilities, except those expressly set
forth herein, nor shall the Administrative Agent have or be deemed to have any
fiduciary relationship with any Lender or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" herein and in the other Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary
or other implied (or express) obligations arising under agency doctrine of any
applicable Law. Instead, such term is used merely as a matter of market custom,
and is intended to create or reflect only an administrative relationship between
independent contracting parties.

         9.02 DELEGATION OF DUTIES. The Administrative Agent may execute any of
its duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel and
other consultants or experts concerning all matters pertaining to such duties.
The Administrative Agent shall not be responsible for the negligence or
misconduct of any agent or attorney-in-fact that it selects in the absence of
gross negligence or willful misconduct.

         9.03 LIABILITY OF ADMINISTRATIVE AGENT. No Agent-Related Person shall
(a) be liable for any action taken or omitted to be taken by any of them under
or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct in connection with its duties expressly set forth herein), or (b) be
responsible in any manner to any Lender or participant for any recital,
statement, representation or warranty made by the Borrower or any officer
thereof, contained herein or in any other Loan Document, or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Administrative Agent under or in connection with, this Agreement or any
other Loan Document, or the validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document, or for any failure
of the Borrower or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No Agent-Related Person shall be under any
obligation to any Lender or participant to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Borrower or any Affiliate thereof.

         9.04 RELIANCE BY ADMINISTRATIVE AGENT.

         (a) The Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, communication, signature,
resolution, representation, notice, consent, certificate, affidavit, letter,
telegram, facsimile, telex or telephone message, electronic mail message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to the
Borrower), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under

                                       55
<PAGE>

any Loan Document unless it shall first receive such advice or concurrence of
the Required Lenders as it deems appropriate and, if it so requests, it shall
first be indemnified to its satisfaction by the Lenders against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. The Administrative Agent shall in all cases
be fully protected in acting, or in refraining from acting, under this Agreement
or any other Loan Document in accordance with a request or consent of the
Required Lenders (or such greater number of Lenders as may be expressly required
hereby in any instance) and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders.

         (b) For purposes of determining compliance with the conditions
specified in Section 4.01, each Lender that has signed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter required thereunder to be consented to or approved by
or acceptable or satisfactory to a Lender unless the Administrative Agent shall
have received notice from such Lender prior to the proposed Closing Date
specifying its objection thereto.

         9.05 NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Lenders,
unless the Administrative Agent shall have received written notice from a Lender
or the Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default." The
Administrative Agent will notify the Lenders of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as may be directed by the Required Lenders in accordance with
Article VIII; provided, however, that unless and until the Administrative Agent
has received any such direction, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable or in the best
interest of the Lenders.

         9.06 CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE
AGENT. Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Administrative Agent
hereafter taken, including any consent to and acceptance of any assignment or
review of the affairs of the Borrower or any Affiliate thereof, shall be deemed
to constitute any representation or warranty by any Agent-Related Person to any
Lender as to any matter, including whether Agent-Related Persons have disclosed
material information in their possession. Each Lender represents to the
Administrative Agent that it has, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and its Subsidiaries, and all applicable bank
or other regulatory Laws relating to the transactions contemplated hereby, and
made its own decision to enter into this Agreement and to extend credit to the
Borrower hereunder. Each Lender also represents that it will, independently and
without reliance upon any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigations as
it deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of the Borrower.
Except for notices, reports and other documents expressly required to be
furnished to the Lenders by the Administrative Agent herein, the Administrative
Agent shall not have any duty or responsibility to provide any Lender with any
credit or other information concerning the business, prospects, operations,
property, financial and other condition or creditworthiness of the Borrower or
any of its Affiliates which may come into the possession of any Agent-Related
Person.

                                       56
<PAGE>

         9.07 INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, the Lenders shall indemnify
upon demand each Agent-Related Person (to the extent not reimbursed by or on
behalf of the Borrower and without limiting the obligation of the Borrower to do
so), pro rata, and hold harmless each Agent-Related Person from and against any
and all Indemnified Liabilities incurred by it; provided, however, that no
Lender shall be liable for the payment to any Agent-Related Person of any
portion of such Indemnified Liabilities to the extent determined in a final,
nonappealable judgment by a court of competent jurisdiction to have resulted
from such Agent-Related Person's own gross negligence or willful misconduct;
provided, however, that no action taken in accordance with the directions of the
Required Lenders shall be deemed to constitute gross negligence or willful
misconduct for purposes of this Section. Without limitation of the foregoing,
each Lender shall reimburse the Administrative Agent upon demand for its ratable
share of any costs or out-of-pocket expenses (including Attorney Costs) incurred
by the Administrative 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, any other Loan
Document, or any document contemplated by or referred to herein, to the extent
that the Administrative Agent is not reimbursed for such expenses by or on
behalf of the Borrower. The undertaking in this Section shall survive
termination of the Aggregate Commitments, the payment of all the Loans and other
Obligations and the resignation of the Administrative Agent.

         9.08 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. Credit Suisse
First Boston and its Affiliates may make loans to, issue letters of credit for
the account of, accept deposits from, acquire equity interests in and generally
engage in any kind of banking, trust, financial advisory, underwriting or other
business with each of the Borrower and its Affiliates as though Credit Suisse
First Boston were not the Administrative Agent hereunder and without notice to
or consent of the Lenders. The Lenders acknowledge that, pursuant to such
activities, Credit Suisse First Boston or its Affiliates may receive information
regarding the Borrower or its Affiliates (including information that may be
subject to confidentiality obligations in favor of the Borrower or such
Affiliate) and acknowledge that the Administrative Agent shall be under no
obligation to provide such information to them. With respect to its Loans,
Credit Suisse First Boston shall have the same rights and powers under this
Agreement as any other Lender and may exercise such rights and powers as though
it were not the Administrative Agent, and the terms "Lender" and "Lenders"
include Credit Suisse First Boston in its individual capacity.

         9.09 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Lenders. If the
Administrative Agent resigns under this Agreement, the Required Lenders shall
appoint from among the Lenders a successor administrative agent for the Lenders,
which successor administrative agent shall be consented to by the Borrower at
all times other than during the existence of an Event of Default (which consent
of the Borrower shall not be unreasonably withheld or delayed). If no successor
administrative agent is appointed prior to the effective date of the resignation
of the Administrative Agent, the Administrative Agent may appoint, after
consulting with the Lenders and the Borrower, a successor administrative agent
from among the Lenders. Upon the acceptance of its appointment as successor
administrative agent hereunder, the Person acting as such successor
administrative agent shall succeed to all the rights, powers and duties of the
retiring Administrative Agent, and the term "Administrative Agent" shall mean
such successor administrative agent and the retiring Administrative Agent's
appointment, powers and duties as Administrative Agent shall be terminated.
After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Article IX and Sections 10.04 and
10.05 shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was Administrative Agent under this Agreement. If no successor
administrative agent has accepted appointment as Administrative Agent by the
date which is 30 days following a retiring Administrative Agent's notice of
resignation, the retiring Administrative

                                       57
<PAGE>

Agent's resignation shall nevertheless thereupon become effective and the
Lenders shall perform all of the duties of the Administrative Agent hereunder
until such time, if any, as the Required Lenders appoint a successor agent as
provided for above.

         9.10 ADMINISTRATIVE AGENT MAY FILE PROOFS OF CLAIM. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Borrower, the Administrative Agent (irrespective of
whether the principal of any Loan shall then be due and payable as herein
expressed or by declaration or otherwise and irrespective of whether the
Administrative Agent shall have made any demand on the Borrower) shall be
entitled and empowered, by intervention in such proceeding or otherwise

         (a) to file and prove a claim for the whole amount of the principal and
interest owing and unpaid in respect of the Loans, and all other Obligations
that are owing and unpaid and to file such other documents as may be necessary
or advisable in order to have the claims of the Lenders and the Administrative
Agent (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Lenders and the Administrative Agent and their
respective agents and counsel and all other amounts due the Lenders and the
Administrative Agent under Sections 2.07 and 10.04) allowed in such judicial
proceeding; and

         (b) to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender to make such payments to the Administrative Agent and, in the event
that the Administrative Agent shall consent to the making of such payments
directly to the Lenders, to pay to the Administrative Agent any amount due for
the reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Sections 2.07 and 10.04.

         Nothing contained herein shall be deemed to authorize the
Administrative Agent to authorize or consent to or accept or adopt on behalf of
any Lender any plan of reorganization, arrangement, adjustment or composition
affecting the Obligations or the rights of any Lender or to authorize the
Administrative Agent to vote in respect of the claim of any Lender in any such
proceeding.

                                   ARTICLE X.
                                  MISCELLANEOUS

         10.01 AMENDMENTS, ETC. No amendment or waiver of any provision of this
Agreement or any other Loan Document, and no consent to any departure by the
Borrower or any Loan Party therefrom, shall be effective unless in writing
signed by the Required Lenders and the Borrower and each Loan Party party
thereto, and acknowledged by the Administrative Agent, and each such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; provided, however, that no such amendment, waiver or
consent shall:

         (a) waive any condition set forth in Section 4.01(a) without the
written consent of each Lender;

         (b) extend or increase the Commitment of any Lender (or reinstate any
Commitment terminated pursuant to Section 8.02) without the written consent of
such Lender;

                                       58
<PAGE>

         (c) postpone any date fixed by this Agreement or any other Loan
Document for any payment of principal, interest, fees or other amounts due to
the Lenders (or any of them) hereunder or under any other Loan Document without
the written consent of each Lender directly affected thereby;

         (d) reduce the principal of, or the rate of interest specified herein
on, any Loan, or (subject to clause (iii) of the second proviso to this Section
10.01) any fees payable hereunder or under any other Loan Document without the
written consent of each Lender directly affected thereby; provided, however,
that only the consent of the Required Lenders shall be necessary to amend the
definition of "Default Rate" or to waive any obligation of the Borrower to pay
interest at the Default Rate;

         (e) change Section 2.11 or Section 8.03 in a manner that would alter
the pro rata sharing of payments required thereby without the written consent of
each Lender; or

         (f) change any provision of this Section or the definition of "Required
Lenders" or any other provision hereof specifying the number or percentage of
Lenders required to amend, waive or otherwise modify any rights hereunder or
make any determination or grant any consent hereunder, without the written
consent of each Lender;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Administrative Agent in addition to the Lenders
required above, affect the rights or duties of the Administrative Agent under
this Agreement or any other Loan Document; (ii) Section 10.07(h) may not be
amended, waived or otherwise modified without the consent of each Granting
Lender all or any part of whose Loans are being funded by an SPC at the time of
such amendment, waiver or other modification; and (iii) the Fee Letter may be
amended, or rights or privileges thereunder waived, in a writing executed only
by the parties thereto. Notwithstanding anything to the contrary herein, no
Defaulting Lender shall have any right to approve or disapprove any amendment,
waiver or consent hereunder, except that the Commitment of such Lender may not
be increased or extended without the consent of such Lender.

         10.02 NOTICES AND OTHER COMMUNICATIONS; FACSIMILE COPIES.

         (a) General. Unless otherwise expressly provided herein, all notices
and other communications provided for hereunder shall be in writing (including
by facsimile transmission). All such written notices shall be mailed, faxed or
delivered to the applicable address, facsimile number or (subject to subsection
(c) below) electronic mail address, and all notices and other communications
expressly permitted hereunder to be given by telephone shall be made to the
applicable telephone number, as follows:

                  (i) if to the Borrower or the Administrative Agent, to the
         address, facsimile number, electronic mail address or telephone number
         specified for such Person on Schedule 10.02 or to such other address,
         facsimile number, electronic mail address or telephone number as shall
         be designated by such party in a notice to the other parties; and

                  (ii) if to any other Lender, to the address, facsimile number,
         electronic mail address or telephone number specified in its
         Administrative Questionnaire or to such other address, facsimile
         number, electronic mail address or telephone number as shall be
         designated by such party in a notice to the Borrower and the
         Administrative Agent.

All such notices and other communications shall be deemed to be given or made
upon the earlier to occur of (i) actual receipt by the relevant party hereto and
(ii) (A) if delivered by hand or by courier, when signed for by or on behalf of
the relevant party hereto; (B) if delivered by mail, four Business Days after

                                       59
<PAGE>

deposit in the mails, postage prepaid; (C) if delivered by facsimile, when sent
and receipt has been confirmed by telephone; and (D) if delivered by electronic
mail (which form of delivery is subject to the provisions of subsection (c)
below), when delivered; provided, however, that notices and other communications
to the Administrative Agent pursuant to Article II shall not be effective until
actually received by the Administrative Agent. In no event shall a voicemail
message be effective as a notice, communication or confirmation hereunder.

         (b) Effectiveness of Facsimile Documents and Signatures. Loan Documents
may be transmitted and/or signed by facsimile. The effectiveness of any such
documents and signatures shall, subject to applicable Law, have the same force
and effect as manually-signed originals and shall be binding on the Borrower,
the other Loan Parties, the Administrative Agent and the Lenders. The
Administrative Agent may also require that any such documents and signatures be
confirmed by a manually-signed original thereof; provided, however, that the
failure to request or deliver the same shall not limit the effectiveness of any
facsimile document or signature.

         (c) Limited Use of Electronic Mail. Electronic mail and Internet and
intranet websites may be used only to distribute routine communications, such as
financial statements and other information as provided in Section 6.02, and to
distribute Loan Documents for execution by the parties thereto, and may not be
used for any other purpose.

         (d) Reliance by Administrative Agent and Lenders. The Administrative
Agent and the Lenders shall be entitled to rely and act upon any notices
(including telephonic Interest Period Notices) purportedly given by or on behalf
of the Borrower or any other Loan Party even if (i) such notices were not made
in a manner specified herein, were incomplete or were not preceded or followed
by any other form of notice specified herein, or (ii) the terms thereof, as
understood by the recipient, varied from any confirmation thereof. The Borrower
shall indemnify each Agent-Related Person and each Lender from all losses,
costs, expenses and liabilities resulting from the reliance by such Person on
each notice purportedly given by or on behalf of the Borrower or any other Loan
Party. All telephonic notices to and other communications with the
Administrative Agent may be recorded by the Administrative Agent, and each of
the parties hereto hereby consents to such recording.

         10.03 NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or the
Administrative Agent to exercise, and no delay by any such Person in exercising,
any right, remedy, power or privilege hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

         10.04 ATTORNEY COSTS, EXPENSES AND TAXES. The Borrower agrees (a) to
pay or reimburse the Administrative Agent for all costs and expenses incurred in
connection with the development, preparation, negotiation and execution of this
Agreement and the other Loan Documents and any amendment, waiver, consent or
other modification of the provisions hereof and thereof (whether or not the
transactions contemplated hereby or thereby are consummated), and the
consummation and administration of the transactions contemplated hereby and
thereby, including all Attorney Costs, and (b) to pay or reimburse the
Administrative Agent and each Lender for all costs and expenses incurred in
connection with the enforcement, attempted enforcement, or preservation of any
rights or remedies under this Agreement or the other Loan Documents (including
all such costs and expenses incurred during any "workout" or restructuring in
respect of the Obligations and during any legal proceeding, including any
proceeding under any Debtor Relief Law), including all Attorney Costs. The
foregoing costs and expenses shall include all search, filing, recording, title
insurance and appraisal charges and fees and taxes

                                       60
<PAGE>

related thereto, and other out-of-pocket expenses incurred by the Administrative
Agent and the cost of independent public accountants and other outside experts
retained by the Administrative Agent or any Lender. All amounts due under this
Section 10.04 shall be payable within ten Business Days after demand therefor.
The agreements in this Section shall survive the termination of the Aggregate
Commitments and repayment of all the Loans and other Obligations.

         10.05 INDEMNIFICATION BY THE BORROWER. Whether or not the transactions
contemplated hereby are consummated, the Borrower shall indemnify and hold
harmless each Agent-Related Person, each Lender and their respective Affiliates,
directors, officers, employees, counsel, agents and attorneys-in-fact
(collectively the "Indemnitees") from and against any and all liabilities,
obligations, losses, damages, penalties, claims, demands, actions, judgments,
suits, costs, expenses and disbursements (including Attorney Costs) of any kind
or nature whatsoever which may at any time be imposed on, incurred by or
asserted against any such Indemnitee in any way relating to or arising out of or
in connection with (a) the execution, delivery, enforcement, performance or
administration of any Loan Document or any other agreement, letter or instrument
delivered in connection with the transactions contemplated thereby or the
consummation of the transactions contemplated thereby, (b) any Commitment or
Loan or the use or proposed use of the proceeds therefrom, (c) any actual or
alleged presence or release of Hazardous Materials on or from any property
currently or formerly owned or operated by the Borrower or any Subsidiary, or
any Environmental Liability related in any way to the Borrower or any
Subsidiary, or (d) any actual or prospective claim, litigation, investigation or
proceeding relating to any of the foregoing, whether based on contract, tort or
any other theory (including any investigation of, preparation for, or defense of
any pending or threatened claim, investigation, litigation or proceeding) and
regardless of whether any Indemnitee is a party thereto (all the foregoing,
collectively, the "Indemnified Liabilities"), in all cases, whether or not
caused by or arising, in whole or in part, out of the negligence of the
Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such liabilities, obligations, losses, damages,
penalties, claims, demands, actions, judgments, suits, costs, expenses or
disbursements are determined by a court of competent jurisdiction by final and
nonappealable judgment to have resulted from the gross negligence or willful
misconduct of such Indemnitee. No Indemnitee shall be liable for any damages
arising from the use by others of any information or other materials obtained
through IntraLinks or other similar information transmission systems in
connection with this Agreement, nor shall any Indemnitee have any liability for
any indirect or consequential damages relating to this Agreement or any other
Loan Document or arising out of its activities in connection herewith or
therewith (whether before or after the Closing Date). All amounts due under this
Section 10.05 shall be payable within ten Business Days after demand therefor.
The agreements in this Section shall survive the resignation of the
Administrative Agent, the replacement of any Lender, the termination of the
Aggregate Commitments and the repayment, satisfaction or discharge of all the
Loans and other Obligations.

         10.06 PAYMENTS SET ASIDE. To the extent that any payment by or on
behalf of the Borrower is made to the Administrative Agent or any Lender, or the
Administrative Agent or any Lender exercises its right of set-off, and such
payment or the proceeds of such set-off or any part thereof is subsequently
invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by the Administrative Agent
or such Lender in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any proceeding under any Debtor Relief Law or
otherwise, then (a) to the extent of such recovery, the obligation or part
thereof originally intended to be satisfied shall be revived and continued in
full force and effect as if such payment had not been made or such set-off had
not occurred, and (b) each Lender severally agrees to pay to the Administrative
Agent upon demand its applicable share of any amount so recovered from or repaid
by the Administrative Agent, plus interest thereon from the date of such demand
to the date such payment is made at a rate per annum equal to the Federal Funds
Rate from time to time in effect.

         10.07 SUCCESSORS AND ASSIGNS.

         (a) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that the Borrower may not assign or otherwise transfer
any of its rights or obligations hereunder without the prior written consent of
the Administrative Agent and each Lender and no Lender may assign or otherwise
transfer any of its rights or obligations hereunder except (i) to an Eligible
Assignee in accordance with the provisions of subsection (b) of this Section,
(ii) by way of participation in accordance with the provisions of subsection (d)
of this Section, (iii) by way of pledge or assignment of a security interest
subject to the restrictions of subsection (f) or (i) of this Section, or (iv) to
an SPC in accordance with the provisions of subsection (h) of this Section (and
any other attempted assignment or transfer by any party hereto shall be null and
void). Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective
successors and assigns permitted hereby, Participants to the extent provided in
subsection (d) of this Section and, to the extent expressly contemplated hereby,
the Indemnitees) any legal or equitable right, remedy or claim under or by
reason of this Agreement.

         (b) Any Lender may at any time assign to one or more Eligible Assignees
all or a portion of its rights and obligations under this Agreement (including
all or a portion of its Commitment and the Loans at the time owing to it);
provided that (i) except in the case of an assignment of the entire remaining
amount of the assigning Lender's Commitment or the Loans at the time owing to it
or in the case of an assignment to a Lender or an Affiliate of a Lender or an
Approved Fund (as defined in subsection (g) of this Section) with respect to a
Lender, the aggregate amount of the Commitment or Loans subject to each such
assignment, determined as of the date the Assignment and Assumption with respect
to such assignment is delivered to the Administrative Agent or, if "Trade Date"
is specified in the Assignment and Assumption, as of the Trade Date, shall not
be less than $1,000,000 unless each of the Administrative Agent and, so long as
no Event of Default has occurred and is continuing, the Borrower otherwise
consents (each such consent not to be unreasonably withheld or delayed); (ii)
each partial assignment shall be made as an assignment of a proportionate part
of all the assigning Lender's rights and obligations under this Agreement with
respect to the Loans or the Commitment assigned; (iii) any assignment of a
Commitment or Loan must be approved by the Administrative Agent unless the
Person that is the proposed assignee is itself a Lender (whether or not the
proposed assignee would otherwise qualify as an Eligible Assignee); and (iv) the
parties to each assignment shall execute and deliver to the Administrative Agent
an Assignment and Assumption, together with a processing and recordation fee of
$3,500. Subject to acceptance and recording thereof by the Administrative Agent
pursuant to subsection (c) of this Section, from and after the effective date
specified in each Assignment and Assumption, the Eligible Assignee thereunder
shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Lender
under this Agreement, and the assigning Lender thereunder shall, to the extent
of the interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 3.01, 3.04, 3.05, 10.04 and 10.05
with respect to facts and circumstances occurring prior to the effective date of
such assignment). Upon request, the Borrower (at its expense) shall execute and
deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of
rights or obligations under this Agreement that does not comply with this
subsection shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
subsection (d) of this Section.

         (c) The Administrative Agent, acting solely for this purpose as an
agent of the Borrower, shall maintain at the Administrative Agent's Office a
copy of each Assignment and Assumption delivered

                                       62
<PAGE>

to it and a register for the recordation of the names and addresses of the
Lenders, and the Commitments of, and principal amounts of the Loans owing to,
each Lender pursuant to the terms hereof from time to time (the "Register"). The
entries in the Register shall be conclusive, and the Borrower, the
Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary. The
Register shall be available for inspection by the Borrower and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

         (d) Any Lender may at any time, without the consent of, or notice to,
the Borrower or the Administrative Agent, sell participations to any Person
(other than a natural person or the Borrower or any of the Borrower's Affiliates
or Subsidiaries) (each, a "Participant") in all or a portion of such Lender's
rights and/or obligations under this Agreement (including all or a portion of
its Commitment or the Loans owing to it); provided that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) the Borrower, the Administrative Agent 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. Any
agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any
amendment, waiver or other modification described in the first proviso to
Section 10.01 that directly affects such Participant. Subject to subsection (e)
of this Section, the Borrower agrees that each Participant shall be entitled to
the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to subsection (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 10.09 as though it were a Lender, provided
such Participant agrees to be subject to Section 2.11 as though it were a
Lender.

         (e) A Participant shall not be entitled to receive any greater payment
under Section 3.01 or 3.04 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with the Borrower's
prior written consent. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 10.15 as though
it were a Lender.

         (f) Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement (including under its Note,
if any) to secure obligations of such Lender, including any pledge or assignment
to secure obligations to a Federal Reserve Bank; provided that no such pledge or
assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

         (g) As used herein, the following terms have the following meanings:

                  "Eligible Assignee" means (a) a Lender; (b) an Affiliate of a
         Lender; (c) an Approved Fund; and (d) any other Person (other than a
         natural person) approved by the Administrative Agent; provided that
         notwithstanding the foregoing, "Eligible Assignee" shall not include
         the Borrower or any of the Borrower's Affiliates or Subsidiaries.

                                       63
<PAGE>

                  "Fund" means any Person (other than a natural person) that is
         (or will be) engaged in making, purchasing, holding or otherwise
         investing in commercial loans and similar extensions of credit in the
         ordinary course of its business.

                  "Approved Fund" means any Fund that is administered or managed
         by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an
         Affiliate of an entity that administers or manages a Lender.

         (h) Notwithstanding anything to the contrary contained herein, any
Lender (a "Granting Lender") may grant to a special purpose funding vehicle
identified as such in writing from time to time by the Granting Lender to the
Administrative Agent and the Borrower (an "SPC") the option to provide all or
any part of any Loan that such Granting Lender would otherwise be obligated to
make pursuant to this Agreement; provided that (i) nothing herein shall
constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects
not to exercise such option or otherwise fails to make all or any part of such
Loan, the Granting Lender shall be obligated to make such Loan pursuant to the
terms hereof. Each party hereto hereby agrees that (i) neither the grant to any
SPC nor the exercise by any SPC of such option shall increase the costs or
expenses or otherwise increase or change the obligations of the Borrower under
this Agreement (including its obligations under Section 3.04), (ii) no SPC shall
be liable for any indemnity or similar payment obligation under this Agreement
for which a Lender would be liable, and (iii) the Granting Lender shall for all
purposes, including the approval of any amendment, waiver or other modification
of any provision of any Loan Document, remain the lender of record hereunder.
The making of a Loan by an SPC hereunder shall utilize the Commitment of the
Granting Lender to the same extent, and as if, such Loan were made by such
Granting Lender. In furtherance of the foregoing, each party hereto hereby
agrees (which agreement shall survive the termination of this Agreement) that,
prior to the date that is one year and one day after the payment in full of all
outstanding commercial paper or other senior debt of any SPC, it will not
institute against, or join any other Person in instituting against, such SPC any
bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding
under the laws of the United States or any State thereof. Notwithstanding
anything to the contrary contained herein, any SPC may (i) with notice to, but
without prior consent of the Borrower and the Administrative Agent, assign all
or any portion of its right to receive payment with respect to any Loan to the
Granting Lender and (ii) disclose on a confidential basis any non-public
information relating to its funding of Loans to any rating agency, commercial
paper dealer or provider of any surety or Guarantee or credit or liquidity
enhancement to such SPC.

         (i) Notwithstanding anything to the contrary contained herein, any
Lender that is a Fund may create a security interest in all or any portion of
the Loans owing to it and the Note, if any, held by it to the trustee for
holders of obligations owed, or securities issued, by such Fund as security for
such obligations or securities, provided that unless and until such trustee
actually becomes a Lender in compliance with the other provisions of this
Section 10.07, (i) no such pledge shall release the pledging Lender from any of
its obligations under the Loan Documents and (ii) such trustee shall not be
entitled to exercise any of the rights of a Lender under the Loan Documents even
though such trustee may have acquired ownership rights with respect to the
pledged interest through foreclosure or otherwise.

         10.08 CONFIDENTIALITY. Each of the Administrative Agent and the Lenders
agrees to maintain the confidentiality of the Information (as defined below),
except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential); (b) to the extent requested
by any regulatory authority; (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process; (d) to any other party
to this Agreement; (e) in

                                       64
<PAGE>

connection with the exercise of any remedies hereunder or any suit, action or
proceeding relating to this Agreement or the enforcement of rights hereunder;
(f) subject to an agreement containing provisions substantially the same as
those of this Section, to (i) any Eligible Assignee of or Participant in, or any
prospective Eligible Assignee of or Participant in, any of its rights or
obligations under this Agreement or (ii) any direct or indirect contractual
counterparty or prospective counterparty (or such contractual counterparty's or
prospective counterparty's professional advisor) to any credit derivative
transaction relating to obligations of the Borrower; (g) with the consent of the
Borrower; (h) to the extent such Information (i) becomes publicly available
other than as a result of a breach of this Section or (ii) becomes available to
the Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Borrower; or (i) to the National Association of Insurance
Commissioners or any other similar organization. In addition, the Administrative
Agent and the Lenders may disclose the existence of this Agreement and
information about this Agreement to market data collectors, similar service
providers to the lending industry, and service providers to the Administrative
Agent and the Lenders in connection with the administration and management of
this Agreement, the other Loan Documents, the Commitments, and the Borrowings.
For the purposes of this Section, "Information" means all information received
from the Borrower relating to the Borrower or its business, other than any such
information that is available to the Administrative Agent or any Lender on a
nonconfidential basis prior to disclosure by the Borrower; provided that, in the
case of information received from the Borrower after the date hereof, such
information is clearly identified in writing at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information
as provided in this Section shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to
its own confidential information.

         10.09 SET-OFF. In addition to any rights and remedies of the Lenders
provided by law, upon the occurrence and during the continuance of any Event of
Default, each Lender is authorized at any time and from time to time, without
prior notice to the Borrower, any such notice being waived by the Borrower 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 by,
and other indebtedness at any time owing by, such Lender to or for the credit or
the account of the Borrower against any and all Obligations owing to such Lender
hereunder or under any other Loan Document, now or hereafter existing,
irrespective of whether or not the Administrative Agent or such Lender shall
have made demand under this Agreement or any other Loan Document and although
such Obligations may be contingent or unmatured or denominated in a currency
different from that of the applicable deposit or indebtedness. Each Lender
agrees promptly to notify the Borrower and the Administrative Agent after any
such set-off and application made by such Lender; provided, however, that the
failure to give such notice shall not affect the validity of such set-off and
application.

         10.10 INTEREST RATE LIMITATION. Notwithstanding anything herein to the
contrary, if at any time the interest rate applicable to any Loan, together with
all fees, charges and other amounts which are treated as interest on such Loan
under applicable law (collectively the "Charges"), shall exceed the maximum
lawful rate (the "Maximum Rate") which may be contracted for, charged, taken,
received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.

                                       65
<PAGE>

         10.11 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         10.12 INTEGRATION. This Agreement, together with the other Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and thereof and supersedes all prior agreements, written
or oral, on such subject matter. In the event of any conflict between the
provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control; provided that the inclusion of
supplemental rights or remedies in favor of the Administrative Agent or the
Lenders in any other Loan Document shall not be deemed a conflict with this
Agreement. Each Loan Document was drafted with the joint participation of the
respective parties thereto and shall be construed neither against nor in favor
of any party, but rather in accordance with the fair meaning thereof.

         10.13 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations
and warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default or Event of Default at the time of any Borrowing, and shall continue
in full force and effect as long as any Loan or any other Obligation hereunder
shall remain unpaid or unsatisfied.

         10.14 SEVERABILITY. If any provision of this Agreement or the other
Loan Documents is held to be illegal, invalid or unenforceable, (a) the
legality, validity and enforceability of the remaining provisions of this
Agreement and the other Loan Documents shall not be affected or impaired thereby
and (b) the parties shall endeavor in good faith negotiations to replace the
illegal, invalid or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         10.15 TAX FORMS. (a) (i) Each Lender that is not a "United States
person" within the meaning of Section 7701(a)(30) of the Code (a "Foreign
Lender") shall deliver to the Administrative Agent, prior to receipt of any
payment subject to withholding under the Code (or upon accepting an assignment
of an interest herein), two duly signed completed copies of either IRS Form
W-8BEN or any successor thereto (relating to such Foreign Lender and entitling
it to an exemption from, or reduction of, withholding tax on all payments to be
made to such Foreign Lender by the Borrower pursuant to this Agreement) or IRS
Form W-8ECI or any successor thereto (relating to all payments to be made to
such Foreign Lender by the Borrower pursuant to this Agreement) or such other
evidence satisfactory to the Borrower and the Administrative Agent that such
Foreign Lender is entitled to an exemption from, or reduction of, U.S.
withholding tax, including any exemption pursuant to Section 881(c) of the Code.
Thereafter and from time to time, each such Foreign Lender shall (A) promptly
submit to the Administrative Agent such additional duly completed and signed
copies of one of such forms (or such successor forms as shall be adopted from
time to time by the relevant United States taxing authorities) as may then be
available under then current United States laws and regulations to avoid, or
such evidence as is satisfactory to the Borrower and the Administrative Agent of
any available exemption from or reduction of, United States withholding taxes in
respect of all payments to be made to such Foreign Lender by the Borrower
pursuant to this Agreement, (B) promptly notify the Administrative Agent of any
change in circumstances which would modify or render invalid any claimed
exemption or reduction, and (C) take such steps as shall not be materially
disadvantageous to it, in the reasonable judgment of such Lender, and as may be
reasonably necessary (including the re-designation of its Lending Office) to
avoid any requirement of applicable

                                       66
<PAGE>

Laws that the Borrower make any deduction or withholding for taxes from amounts
payable to such Foreign Lender.

         (ii) Each Foreign Lender, to the extent it does not act or ceases to
act for its own account with respect to any portion of any sums paid or payable
to such Lender under any of the Loan Documents (for example, in the case of a
typical participation by such Lender), shall deliver to the Administrative Agent
on the date when such Foreign Lender ceases to act for its own account with
respect to any portion of any such sums paid or payable, and at such other times
as may be necessary in the determination of the Administrative Agent (in the
reasonable exercise of its discretion), (A) two duly signed completed copies of
the forms or statements required to be provided by such Lender as set forth
above, to establish the portion of any such sums paid or payable with respect to
which such Lender acts for its own account that is not subject to U.S.
withholding tax, and (B) two duly signed completed copies of IRS Form W-8IMY (or
any successor thereto), together with any information such Lender chooses to
transmit with such form, and any other certificate or statement of exemption
required under the Code, to establish that such Lender is not acting for its own
account with respect to a portion of any such sums payable to such Lender.

         (iii) The Borrower shall not be required to pay any additional amount
to any Foreign Lender under Section 3.01 (A) with respect to any Taxes required
to be deducted or withheld on the basis of the information, certificates or
statements of exemption such Lender transmits with an IRS Form W-8IMY pursuant
to this Section 10.15(a) or (B) if such Lender shall have failed to satisfy the
foregoing provisions of this Section 10.15(a); provided that if such Lender
shall have satisfied the requirement of this Section 10.15(a) on the date such
Lender became a Lender or ceased to act for its own account with respect to any
payment under any of the Loan Documents, nothing in this Section 10.15(a) shall
relieve the Borrower of its obligation to pay any amounts pursuant to Section
3.01 in the event that, as a result of any change in any applicable law, treaty
or governmental rule, regulation or order, or any change in the interpretation,
administration or application thereof, such Lender is no longer properly
entitled to deliver forms, certificates or other evidence at a subsequent date
establishing the fact that such Lender or other Person for the account of which
such Lender receives any sums payable under any of the Loan Documents is not
subject to withholding or is subject to withholding at a reduced rate.

         (iv) The Administrative Agent may, without reduction, withhold any
Taxes required to be deducted and withheld from any payment under any of the
Loan Documents with respect to which the Borrower is not required to pay
additional amounts under this Section 10.15(a).

         (b) Upon the request of the Administrative Agent, each Lender that is a
"United States person" within the meaning of Section 7701(a)(30) of the Code
shall deliver to the Administrative Agent two duly signed completed copies of
IRS Form W-9. If such Lender fails to deliver such forms, then the
Administrative Agent may withhold from any interest payment to such Lender an
amount equivalent to the applicable back-up withholding tax imposed by the Code,
without reduction.

         (c) If any Governmental Authority asserts that the Administrative Agent
did not properly withhold or backup withhold, as the case may be, any tax or
other amount from payments made to or for the account of any Lender, such Lender
shall indemnify the Administrative Agent therefore, including all penalties and
interest, any taxes imposed by any jurisdiction on the amounts payable to the
Administrative Agent under this Section, and costs and expenses (including
Attorney Costs) of the Administrative Agent. The obligation of the Lenders under
this Section shall survive the termination of the Aggregate Commitments, the
repayment of all the Loans and other Obligations hereunder and the resignation
of the Administrative Agent.

         10.16 REPLACEMENT OF LENDERS. Under any circumstances set forth herein
providing that the Borrower shall have the right to replace a Lender as a party
to this Agreement, the Borrower may, upon notice to such Lender and the
Administrative Agent, replace such Lender by causing such Lender to assign its
Commitment (with the assignment fee to be paid by the Borrower in such instance)
pursuant to Section 10.07(b) to one or more other Lenders or Eligible Assignees
procured by the Borrower; provided, however, that if the Borrower elects to
exercise such right with respect to any Lender pursuant to Section 3.06(b) or
Section 3.06(c), it shall be obligated to replace all Lenders that have made
similar requests for compensation pursuant to Section 3.01 or 3.04, or made
similar determinations of illegality pursuant to Section 3.02 and failed to cure
such illegality by designating a different Lending Office. The Borrower shall

         SECTION 2.01. Guarantee. Each Guarantor unconditionally guarantees,
jointly with the other Guarantor and severally, as a primary obligor and not
merely as a surety, the due and punctual payment and performance of the
Obligations; provided that, so long as the Existing Credit Agreements shall
remain in effect, the principal amount of the Indebtedness guaranteed under this
Article II shall at no time exceed the greater of (a) 5% of Net Worth (as
defined in the Existing Credit Agreements, as in effect

                                       2
<PAGE>

on the date hereof) as of the end of the most recent fiscal quarter for which
financial statements shall have been delivered or are required to be delivered
pursuant to Section 6.01(a) or (b) of each Existing Credit Agreement at such
time and (b) any greater amount that would be permitted under the covenants
contained in the Existing Credit Agreements to be guaranteed at such time (it
being the express intention of the parties that the amount of such guarantee
shall not exceed the amount permitted under the Existing Credit Agreements, as
in effect on the date hereof, or any greater amount permitted under such
agreements as a result of their subsequent amendment). Each Guarantor further
agrees that the Obligations may be extended or renewed, in whole or in part,
without notice to or further assent from it, and that it will remain bound upon
its guarantee notwithstanding any extension or renewal of any Obligation. Each
Guarantor waives presentment to, demand of payment from and protest to the
Borrower or any other Loan Party of any of the Obligations, and also waives
notice of acceptance of its guarantee and notice of protest for nonpayment.

         SECTION 2.02. Guarantee of Payment. Each Guarantor further agrees that
its guarantee hereunder constitutes a guarantee of payment when due and not of
collection, and waives any right to require that any resort be had by the
Administrative Agent or any other Secured Party to any security held for the
payment of the Obligations or to any balance of any deposit account or credit on
the books of the Administrative Agent or any other Secured Party in favor of the
Borrower or any other Person.

         SECTION 2.03. No Limitations, Etc. (a) The obligations of each
Guarantor hereunder shall not be subject to any reduction, limitation,
impairment or termination for any reason, including any claim of waiver,
release, surrender, alteration or compromise, and shall not be subject to any
defense or setoff, counterclaim, recoupment or termination whatsoever by reason
of the invalidity, illegality or unenforceability of the Obligations or
otherwise. Without limiting the generality of the foregoing, the obligations of
each Guarantor hereunder shall not be discharged or impaired or otherwise
affected by (i) the failure of the Administrative Agent or any other Secured
Party to assert any claim or demand or to enforce any right or remedy under the
provisions of any Loan Document or otherwise; (ii) any rescission, waiver,
amendment or modification of, or any release from any of the terms or provisions
of, any Loan Document or any other agreement; (iii) the release of any security
held by the Administrative Agent or any other Secured Party for the Obligations
or any of them; (iv) any default, failure or delay, wilful or otherwise, in the
performance of the Obligations; or (v) any other act or omission that may or
might in any manner or to any extent vary the risk of any Guarantor or otherwise
operate as a discharge of any Guarantor as a matter of law or equity (other than
the indefeasible payment in full in cash of all the Obligations). Each Guarantor
expressly authorizes the Secured Parties to take and hold security for the
payment and performance of the Obligations, to exchange, waive or release any or
all such security (with or without consideration), to enforce or apply such
security and direct the order and manner of any sale thereof in their sole
discretion or to release or substitute any one or more other guarantors or
obligors upon or in respect of the Obligations, all without affecting the
obligations of any Guarantor hereunder.

         (b) To the fullest extent permitted by applicable law, each Guarantor
waives any defense based on or arising out of any defense of the Borrower or any
other Loan Party or the unenforceability of the Obligations or any part thereof
from any cause, or the cessation from any cause of the liability of the Borrower
or any other Loan Party, other than the indefeasible payment in full in cash of
all the Obligations. The Administrative Agent and the other Secured Parties may,
at their election, foreclose on any security held by one or more of them by one
or more judicial or nonjudicial sales, accept an assignment of any such security
in lieu of foreclosure, compromise or adjust any part of the Obligations, make
any other accommodation with the Borrower or any other Loan Party or exercise
any other right or remedy available to them against the Borrower or any other
Loan Party, without affecting or impairing in any way the liability of any
Guarantor hereunder except to the extent the Obligations have been fully and
indefeasibly paid in full in cash. To the fullest extent permitted by applicable
law, each Guarantor waives

                                       3

<PAGE>

any defense arising out of any such election even though such election operates,
pursuant to applicable law, to impair or to extinguish any right of
reimbursement or subrogation or other right or remedy of any Guarantor against
the Borrower or any other Loan Party, as the case may be, or any security.

         SECTION 2.04. Reinstatement. Each of the Guarantors agrees that its
guarantee hereunder shall continue to be effective or be reinstated, as the case
may be, if at any time payment, or any part thereof, of any Obligation is
rescinded or must otherwise be restored by the Administrative Agent or any other
Secured Party upon the bankruptcy or reorganization of the Borrower, any other
Loan Party or otherwise.

         SECTION 2.05. Agreement To Pay; Subrogation. In furtherance of the
foregoing and not in limitation of any other right that the Administrative Agent
or any other Secured Party has at law or in equity against any Guarantor by
virtue hereof, upon the failure of the Borrower or any other Loan Party to pay
any Obligation when and as the same shall become due, whether at maturity, by
acceleration, after notice of prepayment or otherwise, each Guarantor hereby
promises to and will forthwith pay, or cause to be paid, to the Administrative
Agent for distribution to the applicable Secured Parties in cash the amount of
such unpaid Obligation; provided that such promise shall be limited as set forth
in the proviso in Section 2.01. Upon payment by any Guarantor of any sums to the
Administrative Agent as provided above, all rights of such Guarantor against the
Borrower or any other Guarantor arising as a result thereof by way of right of
subrogation, contribution, reimbursement, indemnity or otherwise shall in all
respects be subject to Article VI.

         SECTION 2.06. Information. Each Guarantor assumes all responsibility
for being and keeping itself informed of the Borrower's and each other Loan
Party's financial condition and assets, and of all other circumstances bearing
upon the risk of nonpayment of the Obligations and the nature, scope and extent
of the risks that such Guarantor assumes and incurs hereunder, and agrees that
none of the Administrative Agent or the other Secured Parties will have any duty
to advise such Guarantor of information known to it or any of them regarding
such circumstances or risks.

                                   ARTICLE III

                               Pledged Collateral

         SECTION 3.01. Pledge. As security for the payment or performance, as
the case may be, in full of the Obligations, the Grantor hereby assigns and
pledges to the Administrative Agent, its successors and assigns, for the benefit
of the Secured Parties, and hereby grants to the Administrative Agent, its
successors and assigns, for the benefit of the Secured Parties, a security
interest in, all of the Grantor's right, title and interest in, to and under (a)
the Equity Interests owned by it and listed on Schedule I and any other Equity
Interests in the Guarantors obtained in the future by the Grantor and the
certificates representing all such Equity Interests (the "Pledged Interests"),
(b) all other property at any time held directly by the Borrower representing
any interest in property of either Guarantor, either Colonial Pipeline Entity or
the Explorer Pipeline Entity, or the proceeds of any dividend, distribution or
transfer of property to the Borrower by either Guarantor, either Colonial
Pipeline Entity or the Explorer Pipeline Entity, (c) all other property that may
be delivered to and held by the Administrative Agent pursuant to the terms of
this Section 3.01; (d) subject to Section 3.06, all payments of principal or
interest, dividends, cash, instruments and other property from time to time
received, receivable or otherwise distributed in respect of, in exchange for or
upon the conversion of, and all other Proceeds received in respect of, the
securities referred to in clauses (a) and (b) above; (e) subject to Section
3.06, all rights and privileges of such Grantor with respect to the securities
and other property referred to in clauses (a), (b),

                                       4
<PAGE>

(c) and (d) above; and (f) all Proceeds of any of the foregoing (the items
referred to in clauses (a) through (f) above being collectively referred to as
the ("Pledged Collateral").

         TO HAVE AND TO HOLD the Pledged Collateral, together with all right,
title, interest, powers, privileges and preferences pertaining or incidental
thereto, unto the Administrative Agent, its successors and assigns, for the
ratable benefit of the Secured Parties, forever; subject, however, to the terms,
covenants and conditions hereinafter set forth.

         SECTION 3.02. Delivery of the Pledged Collateral. (a) The Grantor
agrees promptly to deliver or cause to be delivered to the Administrative Agent
any and all Pledged Securities.

         (b) Upon delivery to the Administrative Agent, the Pledged Securities
shall be accompanied by stock powers duly executed in blank or other instruments
of transfer satisfactory to the Administrative Agent and by such other
instruments and documents as the Administrative Agent may reasonably request.
The delivery of Pledged Securities shall be accompanied by a schedule describing
the securities, which schedule shall be attached hereto as Schedule II and made
a part hereof; provided that failure to attach any such schedule hereto shall
not affect the validity of such pledge of such Pledged Securities. Each schedule
so delivered shall supplement any prior schedules so delivered.

         SECTION 3.03. Representations, Warranties and Covenants. (I) The
Grantor represents, warrants and covenants to and with the Administrative Agent,
for the benefit of the Secured Parties, that:

                  (a) Schedule I correctly sets forth the percentage of the
         issued and outstanding shares of each class of the Equity Interests of
         the issuer thereof represented by the Pledged Interests and includes
         all Equity Interests required to be pledged hereunder in order to
         satisfy the Collateral and Guarantee Requirement;

                  (b) the Pledged Interests have been duly and validly
         authorized and issued by the issuers thereof and are fully paid and
         nonassessable;

                  (c) except for the security interests granted hereunder, the
         Grantor (i) is and will continue to be the direct owner, beneficially
         and of record, of the Pledged Securities indicated on Schedule I as
         owned by the Grantor, (ii) holds the same free and clear of all Liens,
         (iii) will make no assignment, pledge, hypothecation or transfer of, or
         create or permit to exist any security interest in or other Lien on,
         the Pledged Collateral, other than Liens created by this Agreement, and
         (iv) subject to Section 3.06, will cause any and all Pledged
         Collateral, whether for value paid by the Grantor or otherwise, to be
         forthwith deposited with the Administrative Agent and pledged or
         assigned hereunder;

                  (d) except for restrictions and limitations imposed by the
         Loan Documents or securities laws generally, the Pledged Collateral is
         and will continue to be freely transferable and assignable, and none of
         the Pledged Collateral is or will be subject to any option, right of
         first refusal, shareholders agreement, charter or by-law provisions or
         contractual restriction of any nature that might prohibit, impair,
         delay or otherwise affect the pledge of such Pledged Collateral
         hereunder, the sale or disposition thereof pursuant hereto or the
         exercise by the Administrative Agent of rights and remedies hereunder;

                  (e) the Grantor (i) has the power and authority to pledge the
         Pledged Collateral pledged by it hereunder in the manner hereby done or
         contemplated and (ii) will defend its title or interest

                                       5
<PAGE>

         thereto or therein against any and all Liens (other than the Lien
         created by this Agreement), however arising, of all Persons whomsoever;

                  (f) no consent of any other Person (including stockholders,
         partners, members or creditors of the Grantor, any Governmental
         Authority or any securities exchange) was or is necessary to the
         validity of the pledge effected hereby (other than such as have been
         obtained and are in full force and effect);

                  (g) by virtue of the execution and delivery by the Grantor of
         this Agreement, when any Pledged Securities are delivered to the
         Administrative Agent in accordance with this Agreement, the
         Administrative Agent will obtain a legal, valid and perfected first
         priority lien upon and security interest in such Pledged Securities as
         security for the payment and performance of the Obligations; and

                  (h) the pledge effected hereby is effective to vest in the
         Administrative Agent, for the benefit of the Secured Parties, the
         rights of the Administrative Agent in the Pledged Collateral as set
         forth herein.

         (II) Each Guarantor represents, warrants and covenants to and with the
Administrative Agent, for the benefit of the Secured Parties, that:

                  (a) Schedule 5.19 to the Credit Agreement correctly sets forth
         the percentage of the issued and outstanding shares of each class of
         the Equity Interests in the Colonial Pipeline Entities and the Explorer
         Pipeline Entity owned by such Guarantor (collectively, the "Pipeline
         Interests");

                  (b) such Guarantor (i) is and will continue to be the direct
         owner, beneficially and of record, of the Pipeline Interests indicated
         on such Schedule 5.19 as owned by such Guarantor, other than as a
         result of any dividend, distribution or transfer of a Pipeline Interest
         to the Grantor that (x) cannot be prohibited by this Agreement without
         violation of any debt instrument of the Grantor in effect on the date
         hereof and (y) is not consummated prior to the perfection of the
         security interest in the property that is the subject of such dividend,
         distribution or transfer granted under clause (b) of Section 3.01 of
         this Agreement, (ii) holds the same free and clear of all Liens, and
         (iii) will make no assignment, pledge, hypothecation or transfer of, or
         create or permit to exist any security interest in or other Lien on,
         any Pipeline Interest (except as contemplated by clause (i));

                  (c) such Guarantor (i) has the power and authority to execute
         and deliver and perform its obligations under this Agreement and (ii)
         will defend its title or interest to or in its Pipeline Interests
         against any and all Liens (other than any Lien created by this
         Agreement), however arising, of all Persons whomsoever; and

                  (d) no consent of any other Person (including stockholders,
         partners, members or creditors of the Guarantor, any Governmental
         Authority or any securities exchange) was or is necessary to the
         agreements of such Guarantor hereunder (other than such as have been
         obtained and are in full force and effect).

         SECTION 3.04. Certification of Limited Liability Company Interests.
Each interest in any limited liability company pledged hereunder shall be
represented by a certificate, shall be a "security" within the meaning of
Article 8 of the New

                                       6
<PAGE>

York UCC and shall be governed by Article 8 of the New York UCC. The charter
documents of each such limited liability company shall include an express
provision providing that each interest in such entity "is a security governed by
Article 8 of the Uniform Commercial Code in effect in the State of New York on
the date hereof".

         SECTION 3.05. Registration in Nominee Name; Denominations. The
Administrative Agent, on behalf of the Secured Parties, shall have the right (in
its sole and absolute discretion) to hold the Pledged Securities in its own name
as pledgee, the name of its nominee (as pledgee or as sub-agent) or the name of
the Grantor, endorsed or assigned in blank or in favor of the Administrative
Agent. The Grantor will promptly give to the Administrative Agent copies of any
notices or other communications received by it with respect to Pledged
Securities registered in the name of the Grantor. The Administrative Agent shall
at all times have the right to exchange the certificates representing Pledged
Securities for certificates of smaller or larger denominations for any purpose
consistent with this Agreement.

         SECTION 3.06. Voting Rights; Dividends and Interest, etc. (a) Unless
and until an Event of Default shall have occurred and be continuing and the
Administrative Agent shall have notified the Grantor that its rights under this
Section are being suspended:

                  (i) The Grantor shall be entitled to exercise any and all
         voting and/or other consensual rights and powers inuring to an owner of
         Pledged Securities or any part thereof for any purpose consistent with
         the terms of this Agreement, the Credit Agreement and the other Loan
         Documents; provided that such rights and powers shall not be exercised
         in any manner that could materially and adversely affect the rights
         inuring to a holder of any Pledged Securities or the rights and
         remedies of any of the Administrative Agent or the other Secured
         Parties under this Agreement or the Credit Agreement or any other Loan
         Document or the ability of the Secured Parties to exercise the same.

                  (ii) The Administrative Agent shall execute and deliver to the
         Grantor, or cause to be executed and delivered to the Grantor, all such
         proxies, powers of attorney and other instruments as the Grantor may
         reasonably request for the purpose of enabling the Grantor to exercise
         the voting and/or consensual rights and powers it is entitled to
         exercise pursuant to subparagraph (i) above.

                  (iii) The Grantor shall be entitled to receive and retain any
         and all dividends, interest, principal and other distributions paid on
         or distributed in respect of the Pledged Securities to the extent and
         only to the extent that such dividends, interest, principal and other
         distributions are permitted by, and otherwise paid or distributed in
         accordance with, the terms and conditions of the Credit Agreement, the
         other Loan Documents and applicable laws; provided that any noncash
         dividends, interest, principal or other distributions, whether
         resulting from a subdivision, combination or reclassification of the
         outstanding Equity Interests of the issuer of any Pledged Securities or
         received in exchange for Pledged Securities or any part thereof, or in
         redemption thereof, or as a result of any merger, consolidation,
         acquisition or other exchange of assets to which such issuer may be a
         party or otherwise, shall be and become part of the Pledged Collateral,
         and, if received by the Grantor, shall not be commingled by the Grantor
         with any of its other funds or property but shall be held separate and
         apart therefrom, shall be held in trust for the benefit of the
         Administrative Agent and shall be forthwith delivered to the
         Administrative Agent in the same form as so received (with any
         necessary endorsement).

         (b) Upon the occurrence and during the continuance of an Event of
Default, after the Administrative Agent shall have notified the Grantor of the
suspension of its rights under paragraph

                                       7
<PAGE>

(a)(iii) of this Section 3.06, then all rights of the Grantor to dividends,
interest, principal or other distributions that the Grantor is authorized to
receive pursuant to paragraph (a)(iii) of this Section 3.06 shall cease, and all
such rights shall thereupon become vested in the Administrative Agent, which
shall have the sole and exclusive right and authority to receive and retain such
dividends, interest, principal or other distributions. All dividends, interest,
principal or other distributions received by the Grantor contrary to the
provisions of this Section 3.06 shall be held in trust for the benefit of the
Administrative Agent, shall be segregated from other property or funds of the
Grantor and shall be forthwith delivered to the Administrative Agent upon demand
in the same form as so received (with any necessary endorsement). Any and all
money and other property paid over to or received by the Administrative Agent
pursuant to the provisions of this paragraph (b) shall be retained by the
Administrative Agent in an account to be established by the Administrative Agent
upon receipt of such money or other property and shall be applied in accordance
with the provisions of Section 5.02. After all Events of Default have been cured
or waived and the Grantor has delivered to the Administrative Agent certificates
to that effect, the Administrative Agent shall, promptly after all such Events
of Default have been cured or waived, repay to the Grantor (without interest)
all dividends, interest, principal or other distributions that such Grantor
would otherwise be permitted to retain pursuant to the terms of paragraph
(a)(iii) of this Section 3.06 and that remain in such account.

         (c) Upon the occurrence and during the continuance of an Event of
Default, after the Administrative Agent shall have notified the Grantor of the
suspension of its rights under paragraph (a)(i) of this Section 3.06, then all
rights of the Grantor to exercise the voting and consensual rights and powers it
is entitled to exercise pursuant to paragraph (a)(i) of this Section 3.06, and
the obligations of the Administrative Agent under paragraph (a)(ii) of this
Section 3.06, shall cease, and all such rights shall thereupon become vested in
the Administrative Agent, which shall have the sole and exclusive right and
authority to exercise such voting and consensual rights and powers; provided
that, unless otherwise directed by the Required Lenders, the Administrative
Agent shall have the right from time to time following and during the
continuance of an Event of Default to permit the Grantor to exercise such
rights.

         (d) Any notice given by the Administrative Agent to the Grantor
suspending its rights under paragraph (a) of this Section 3.06 (i) may be given
by telephone if promptly confirmed in writing and (ii) may suspend the rights of
the Grantor under paragraph (a)(i) or paragraph (a)(iii) in part without
suspending all such rights (as specified by the Administrative Agent in its sole
and absolute discretion) and without waiving or otherwise affecting the
Administrative Agent's rights to give additional notices from time to time
suspending other rights so long as an Event of Default has occurred and is
continuing.

                                   ARTICLE IV

                             [Intentionally Omitted]

                                    ARTICLE V

                                    Remedies

         SECTION 5.01. Remedies upon Default. Upon the occurrence and during the
continuance of an Event of Default, the Grantor agrees that the Administrative
Agent shall have the right, subject to the mandatory requirements of applicable
law, to sell or otherwise dispose of all or any part of

                                       8
<PAGE>

the Collateral at a public or private sale or at any broker's board or on any
securities exchange, for cash, upon credit or for future delivery as the
Administrative Agent shall deem appropriate. The Administrative Agent shall be
authorized at any such sale (if it deems it advisable to do so) to restrict the
prospective bidders or purchasers to Persons who will represent and agree that
they are purchasing the Collateral for their own account for investment and not
with a view to the distribution or sale thereof, and upon consummation of any
such sale the Administrative Agent shall have the right to assign, transfer and
deliver to the purchaser or purchasers thereof the Collateral so sold. Each such
purchaser at any such sale shall hold the property sold absolutely, free from
any claim or right on the part of the Grantor, and the Grantor hereby waives (to
the extent permitted by law) all rights of redemption, stay and appraisal which
the Grantor now has or may at any time in the future have under any rule of law
or statute now existing or hereafter enacted.

         The Administrative Agent shall give the Grantor 10 days' written notice
(which the Grantor agrees is reasonable notice within the meaning of Section
9-611 of the New York UCC or its equivalent in other jurisdictions) of the
Administrative Agent's intention to make any sale of Collateral. Such notice, in
the case of a public sale, shall state the time and place for such sale and, in
the case of a sale at a broker's board or on a securities exchange, shall state
the board or exchange at which such sale is to be made and the day on which the
Collateral, or portion thereof, will first be offered for sale at such board or
exchange. Any such public sale shall be held at such time or times within
ordinary business hours and at such place or places as the Administrative Agent
may fix and state in the notice (if any) of such sale. At any such sale, the
Collateral, or portion thereof, to be sold may be sold in one lot as an entirety
or in separate parcels, as the Administrative Agent may (in its sole and
absolute discretion) determine. The Administrative Agent shall not be obligated
to make any sale of any Collateral if it shall determine not to do so,
regardless of the fact that notice of sale of such Collateral shall have been
given. The Administrative Agent may, without notice or publication, adjourn any
public or private sale or cause the same to be adjourned from time to time by
announcement at the time and place fixed for sale, and such sale may, without
further notice, be made at the time and place to which the same was so
adjourned. In case any sale of all or any part of the Collateral is made on
credit or for future delivery, the Collateral so sold may be retained by the
Administrative Agent until the sale price is paid by the purchaser or purchasers
thereof, but the Administrative Agent shall not incur any liability in case any
such purchaser or purchasers shall fail to take up and pay for the Collateral so
sold and, in case of any such failure, such Collateral may be sold again upon
like notice. At any public (or, to the extent permitted by law, private) sale
made pursuant to this Section, any Secured Party may bid for or purchase, free
(to the extent permitted by law) from any right of redemption, stay, valuation
or appraisal on the part of the Grantor (all said rights being also hereby
waived and released to the extent permitted by law), the Collateral or any part
thereof offered for sale and may make payment on account thereof by using any
claim then due and payable to such Secured Party from the Grantor as a credit
against the purchase price, and such Secured Party may, upon compliance with the
terms of sale, hold, retain and dispose of such property without further
accountability to any Grantor therefor. For purposes hereof, a written agreement
to purchase the Collateral or any portion thereof shall be treated as a sale
thereof; the Administrative Agent shall be free to carry out such sale pursuant
to such agreement and the Grantor shall not be entitled to the return of the
Collateral or any portion thereof subject thereto, notwithstanding the fact that
after the Administrative Agent shall have entered into such an agreement all
Events of Default shall have been remedied and the Obligations paid in full. As
an alternative to exercising the power of sale herein conferred upon it, the
Administrative Agent may proceed by a suit or suits at law or in equity to
foreclose this Agreement and to sell the Collateral or any portion thereof
pursuant to a judgment or decree of a court or courts having competent
jurisdiction or pursuant to a proceeding by a court-appointed receiver. Any sale
pursuant to the provisions of this Section 5.01 shall be deemed to conform to
the commercially reasonable standards as provided in Section 9-610(b) of the New
York UCC or its equivalent in other jurisdictions.

                                       9
<PAGE>

         SECTION 5.02. Application of Proceeds. The Administrative Agent shall
apply the proceeds of any collection or sale of Collateral, including any
Collateral consisting of cash, as follows:

                  FIRST, to the payment of all costs and expenses incurred by
         the Administrative Agent in connection with such collection or sale or
         otherwise in connection with this Agreement, any other Loan Document or
         any of the Obligations, including all court costs and the fees and
         expenses of its agents and legal counsel, the repayment of all advances
         made by the Administrative Agent hereunder or under any other Loan
         Document on behalf of the Grantor and any other costs or expenses
         incurred in connection with the exercise of any right or remedy
         hereunder or under any other Loan Document;

                  SECOND, to the payment in full of the Obligations (the amounts
         so applied to be distributed among the Secured Parties pro rata in
         accordance with the amounts of the Obligations owed to them on the date
         of any such distribution); and

                  THIRD, to the Grantor, its successors or assigns, or as a
         court of competent jurisdiction may otherwise direct.

The Administrative Agent shall have absolute discretion as to the time of
application of any such proceeds, moneys or balances in accordance with this
Agreement. Upon any sale of Collateral by the Administrative Agent (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the Administrative Agent or of the officer making the sale shall
be a sufficient discharge to the purchaser or purchasers of the Collateral so
sold and such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Administrative
Agent or such officer or be answerable in any way for the misapplication
thereof.

         SECTION 5.03. Securities Act, etc. In view of the position of the
Grantor in relation to the Pledged Collateral, or because of other current or
future circumstances, a question may arise under the Securities Act of 1933, as
now or hereafter in effect, or any similar statute hereafter enacted analogous
in purpose or effect (such Act and any such similar statute as from time to time
in effect being called the "Federal Securities Laws") with respect to any
disposition of the Pledged Collateral permitted hereunder. The Grantor
understands that compliance with the Federal Securities Laws might very strictly
limit the course of conduct of the Administrative Agent if the Administrative
Agent were to attempt to dispose of all or any part of the Pledged Collateral,
and might also limit the extent to which or the manner in which any subsequent
transferee of any Pledged Collateral could dispose of the same. Similarly, there
may be other legal restrictions or limitations affecting the Administrative
Agent in any attempt to dispose of all or part of the Pledged Collateral under
applicable Blue Sky or other state securities laws or similar laws analogous in
purpose or effect. The Grantor recognizes that in light of such restrictions and
limitations the Administrative Agent may, with respect to any sale of the
Pledged Collateral, limit the purchasers to those who will agree, among other
things, to acquire such Pledged Collateral for their own account, for
investment, and not with a view to the distribution or resale thereof. The
Pledgor acknowledges and agrees that in light of such restrictions and
limitations, the Administrative Agent, in its sole and absolute discretion (a)
may proceed to make such a sale whether or not a registration statement for the
purpose of registering such Pledged Collateral or part thereof shall have been
filed under the Federal Securities Laws and (b) may approach and negotiate with
a single potential purchaser to effect such sale. The Grantor acknowledges and
agrees that any such sale might result in prices and other terms less favorable
to the seller than if such sale were a public sale without such restrictions. In
the event of any such sale, the Administrative Agent shall incur no
responsibility or liability for selling all or any part of the Pledged
Collateral at a price that the Administrative Agent, in its sole and absolute
discretion, may in good faith deem reasonable under the circumstances,
notwithstanding the possibility that a substantially higher price

                                       10
<PAGE>

might have been realized if the sale were deferred until after registration as
aforesaid or if more than a single purchaser were approached. The provisions of
this Section 5.03 will apply notwithstanding the existence of a public or
private market upon which the quotations or sales prices may exceed
substantially the price at which the Administrative Agent sells.

         SECTION 5.04. Registration, etc. The Grantor agrees that, upon the
occurrence and during the continuance of an Event of Default hereunder, if for
any reason the Administrative Agent desires to sell any of the Pledged
Collateral at a public sale, it will, at any time and from time to time, upon
the written request of the Administrative Agent, use its best efforts to take or
to cause the issuer of such Pledged Collateral to take such action and prepare,
distribute and/or file such documents, as are required or advisable in the
reasonable opinion of counsel for the Administrative Agent to permit the public
sale of such Pledged Collateral. The Grantor further agrees to indemnify, defend
and hold harmless the Administrative Agent, each other Secured Party, any
underwriter and their respective officers, directors, affiliates and controlling
persons from and against all loss, liability, expenses, costs of counsel
(including, without limitation, reasonable fees and expenses to the
Administrative Agent of legal counsel), and claims (including the costs of
investigation) that they may incur insofar as such loss, liability, expense or
claim arises out of or is based upon any alleged untrue statement of a material
fact contained in any prospectus (or any amendment or supplement thereto) or in
any notification or offering circular, or arises out of or is based upon any
alleged omission to state a material fact required to be stated therein or
necessary to make the statements in any thereof not misleading, except insofar
as the same may have been caused by any untrue statement or omission based upon
information furnished in writing to the Grantor or the issuer of such Pledged
Collateral by the Administrative Agent or any other Secured Party expressly for
use therein. The Grantor further agrees, upon such written request referred to
above, to use its best efforts to qualify, file or register, or cause the issuer
of such Pledged Collateral to qualify, file or register, any of the Pledged
Collateral under the Blue Sky or other securities laws of such states as may be
requested by the Administrative Agent and keep effective, or cause to be kept
effective, all such qualifications, filings or registrations. The Grantor will
bear all costs and expenses of carrying out its obligations under this Section
5.04. The Grantor acknowledges that there is no adequate remedy at law for
failure by it to comply with the provisions of this Section 5.04 and that such
failure would not be adequately compensable in damages, and therefore agrees
that its agreements contained in this Section 5.04 may be specifically enforced.

                                   ARTICLE VI

                    Indemnity, Subrogation and Subordination

         SECTION 6.01. Indemnity and Subrogation. In addition to all such rights
of indemnity and subrogation as the Guarantors may have under applicable law
(but subject to Section 6.03), the Borrower agrees that in the event a payment
shall be made by any Guarantor under this Agreement, the Borrower shall
indemnify such Guarantor for the full amount of such payment and such Guarantor
shall be subrogated to the rights of the Person to whom such payment shall have
been made to the extent of such payment (it being understood that in no
circumstances will the Secured Parties receive payment in excess of the
Obligations).

         SECTION 6.02. Contribution and Subrogation. Each Guarantor (a
"Contributing Guarantor") agrees (subject to Section 6.03) that, in the event a
payment shall be made by any other Guarantor hereunder in respect of any
Obligation and such other Guarantor (the "Claiming Guarantor") shall not have
been fully indemnified by the Borrower as provided in Section 6.01, the
Contributing Guarantor shall indemnify the Claiming Guarantor in an amount equal
to the amount of such payment multiplied by a fraction of which the numerator
shall be the net worth of the Contributing Guarantor on

                                       11
<PAGE>

the date hereof and the denominator shall be the aggregate net worth of both
Guarantors on the date hereof. Any Contributing Guarantor making any payment to
a Claiming Guarantor pursuant to this Section 6.02 shall be subrogated to the
rights of such Claiming Guarantor under Section 6.01 to the extent of such
payment.

         SECTION 6.03. Subordination. (a) Notwithstanding any provision of this
Agreement to the contrary, all rights of the Guarantors under Sections 6.01 and
6.02 and all other rights of indemnity, contribution or subrogation under
applicable law or otherwise shall be fully subordinated to the indefeasible
payment in full in cash of the Obligations. No failure on the part of the
Borrower or any Guarantor to make the payments required by Sections 6.01 and
6.02 (or any other payments required under applicable law or otherwise) shall in
any respect limit the obligations and liabilities of any Guarantor with respect
to its obligations hereunder, and each Guarantor shall remain liable for the
full amount of the obligations of such Guarantor hereunder.

         (b) The Borrower and each Guarantor hereby agrees that all Indebtedness
and other monetary obligations owed by it to the Borrower or any Guarantor shall
be fully subordinated to the indefeasible payment in full in cash of the
Obligations.

                                   ARTICLE VII

                                  Miscellaneous

         SECTION 7.01. Notices. All communications and notices hereunder shall
(except as otherwise expressly permitted herein) be in writing and given as
provided in Section 10.02 of the Credit Agreement. All communications and
notices hereunder to any Guarantor shall be given to it in care of the Borrower
as provided in Section 10.02 of the Credit Agreement.

         SECTION 7.02. Security Interest Absolute. All rights of the
Administrative Agent hereunder, the grant of a security interest in the Pledged
Collateral and all obligations of the Grantor and Pledgor hereunder to the
fullest extent permitted by law shall be absolute and unconditional irrespective
of (a) any lack of validity or enforceability of the Credit Agreement, any other
Loan Document, any agreement with respect to any of the Obligations or any other
agreement or instrument relating to any of the foregoing, (b) any change in the
time, manner or place of payment of, or in any other term of, all or any of the
Obligations, or any other amendment or waiver of or any consent to any departure
from the Credit Agreement, any other Loan Document or any other agreement or
instrument, (c) any exchange, release or non-perfection of any Lien on other
collateral, or any release or amendment or waiver of or consent under or
departure from any guarantee, securing or guaranteeing all or any of the
Obligations, or (d) any other circumstance that might otherwise constitute a
defense available to, or a discharge of, the Grantor or Pledgor in respect of
the Obligations or this Agreement.

         SECTION 7.03. Survival of Agreement. All covenants, agreements,
representations and warranties made by the Loan Parties in the Loan Documents
and in the certificates or other instruments prepared or delivered in connection
with or pursuant to this Agreement or any other Loan Document shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of the Loan Documents and the making of any
Loans, regardless of any investigation made by any such other party or on its
behalf and notwithstanding that the Administrative Agent or any Lender may have
had notice or knowledge of any Default or incorrect representation or warranty
at the time any credit is extended under the Credit Agreement, and shall
continue in full force and effect as long as the principal of or any accrued
interest on any Loan or any fee or any other amount payable under any Loan
Document is outstanding and unpaid.

         SECTION 7.04. Binding Effect; Several Agreement. This Agreement shall
become effective as to any Loan Party when a counterpart hereof executed on
behalf of such Loan Party shall have been delivered to the Administrative Agent
and a counterpart hereof shall have been executed on behalf of the
Administrative Agent, and thereafter shall be binding upon such Loan Party and
the Administrative Agent and their respective permitted successors and assigns,
and shall inure to the benefit of such Loan Party, the Administrative Agent and
the other Secured Parties and their respective successors and assigns, except
that no Loan Party shall have the right to assign or transfer its rights or
obligations hereunder or any interest herein or in the Collateral or Pledged
Collateral (and any such assignment or transfer shall be void) except as
expressly contemplated by this Agreement or the Credit Agreement. This Agreement
shall be construed as a separate agreement with respect to each Loan Party and
may be amended, modified, supplemented, waived or released with respect to any
Loan Party without the approval of any other Loan Party and without affecting
the obligations of any other Loan Party hereunder.

         SECTION 7.05. Successors and Assigns. Whenever in this Agreement any of
the parties hereto is referred to, such reference shall be deemed to include the
permitted successors and assigns of such party; and all covenants, promises and
agreements by or on behalf of the Grantor or the Administrative Agent that are
contained in this Agreement shall bind and inure to the benefit of their
respective successors and assigns.

         SECTION 7.06. Administrative Agent's Fees and Expenses;
Indemnification. (a) The parties hereto agree that the Administrative Agent
shall be entitled to reimbursement of its expense incurred hereunder as provided
in Section 10.04 of the Credit Agreement.

         (b) Without limitation of its indemnification obligations under the
other Loan Documents, the Grantor and each Guarantor jointly and severally agree
to indemnify the Administrative Agent and the other Indemnitees (as defined in
Section 10.05 of the Credit Agreement) against, and hold each Indemnitee
harmless from, any and all losses, claims, damages, liabilities and related
expenses, including the fees, charges and disbursements of any counsel for any
Indemnitee, incurred by or asserted against any Indemnitee arising out of, in
connection with, or as a result of, the execution, delivery or performance of
this Agreement or any claim, litigation, investigation or proceeding relating to
any of the foregoing agreement or instrument contemplated hereby, or to the
Collateral, whether or not any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses are determined by a
court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or wilful misconduct of such Indemnitee.

         (c) Any such amounts payable as provided hereunder shall be additional
Obligations secured hereby and by the other Security Documents. The provisions
of this Section 7.06 shall remain operative and in full force and effect
regardless of the termination of this Agreement or any other Loan Document, the
consummation of the transactions contemplated hereby, the repayment of any of
the Obligations, the invalidity or unenforceability of any term or provision of
this Agreement or any other Loan Document, or any investigation made by or on
behalf of the Administrative Agent or any other Secured Party. All amounts due
under this Section 7.06 shall be payable on written demand therefor.

         SECTION 7.07. Administrative Agent Appointed Attorney-in-Fact. The
Grantor hereby appoints the Administrative Agent its attorney-in-fact for the
purpose of carrying out the provisions of this Agreement and taking any action
and executing any instrument that the Administrative Agent may deem necessary or
advisable to accomplish the purposes hereof, which appointment is irrevocable
and coupled with an interest. Without limiting the generality of the foregoing,
the Administrative Agent shall

                                       13
<PAGE>

have the right, upon the occurrence and during the continuance of an Event of
Default, with full power of substitution either in the Administrative Agent's
name or in the name of the Grantor (a) to receive, endorse, assign and/or
deliver any and all notes, acceptances, checks, drafts, money orders or other
evidences of payment relating to the Collateral or any part thereof; (b) to
demand, collect, receive payment of, give receipt for and give discharges and
releases of all or any of the Collateral; (c) to commence and prosecute any and
all suits, actions or proceedings at law or in equity in any court of competent
jurisdiction to collect or otherwise realize on all or any of the Collateral or
to enforce any rights in respect of any Collateral; (d) to settle, compromise,
compound, adjust or defend any actions, suits or proceedings relating to all or
any of the Collateral; and (e) to use, sell, assign, transfer, pledge, make any
agreement with respect to or otherwise deal with all or any of the Collateral,
and to do all other acts and things necessary to carry out the purposes of this
Agreement, as fully and completely as though the Administrative Agent were the
absolute owner of the Collateral for all purposes; provided, that nothing herein
contained shall be construed as requiring or obligating the Administrative Agent
to make any commitment or to make any inquiry as to the nature or sufficiency of
any payment received by the Administrative Agent, or to present or file any
claim or notice, or to take any action with respect to the Collateral or any
part thereof or the moneys due or to become due in respect thereof or any
property covered thereby. The Administrative Agent and the other Secured Parties
shall be accountable only for amounts actually received as a result of the
exercise of the powers granted to them herein, and neither they nor their
officers, directors, employees or agents shall be responsible to the Grantor for
any act or failure to act hereunder, except for their own gross negligence or
wilful misconduct.

         SECTION 7.08. APPLICABLE LAW. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

         SECTION 7.09. Waivers; Amendment. (a) No failure or delay by the
Administrative Agent or any Lender in exercising any right or power hereunder or
under any other Loan Document shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Administrative Agent and the Lenders hereunder and under the
other Loan Documents are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of any Loan
Document or consent to any departure by any Loan Party therefrom shall in any
event be effective unless the same shall be permitted by paragraph (b) of this
Section, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. Without limiting the generality of
the foregoing, the making of a Loan shall not be construed as a waiver of any
Default, regardless of whether the Administrative Agent or any Lender may have
had notice or knowledge of such Default at the time. No notice or demand on any
Loan Party in any case shall entitle any Loan Party to any other or further
notice or demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Administrative Agent and the Loan Party or Loan Parties with
respect to which such waiver, amendment or modification is to apply, subject to
any consent required in accordance with Section 10.01 of the Credit Agreement.

         SECTION 7.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT

                                       14
<PAGE>

OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         SECTION 7.11. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby (it being understood that the invalidity of a particular
provision in a particular jurisdiction shall not in and of itself affect the
validity of such provision in any other jurisdiction). The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

         SECTION 7.12. Counterparts. This Agreement may be executed in
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute single contract, and shall become effective as
provided in Section 7.04. Delivery of an executed signature page to this
Agreement by facsimile transmission shall be as effective as delivery of a
manually signed counterpart of this Agreement.

         SECTION 7.13. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 7.14. Jurisdiction; Consent to Service of Process. (a) Each of
the Loan Parties 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 any other Loan Document, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement or any other Loan Document shall
affect any right that the Administrative Agent, the Issuing Bank or any Lender
may otherwise have to bring any action or proceeding relating to this Agreement
or any other Loan Document against Holdings, the Borrower or its properties in
the courts of any jurisdiction.

         (b) Each of the Loan Parties hereby irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection which it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement or any other
Loan Document in any court referred to in paragraph (a) of this Section. Each of
the parties hereto hereby irrevocably waives, to the fullest extent permitted by
law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

                                       15
<PAGE>

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 7.01. Nothing in this
Agreement or any other Loan Document will affect the right of any party to this
Agreement to serve process in any other manner permitted by law.

         SECTION 7.15. Termination or Release. (a) This Agreement, the Guarantee
and all other security interests granted hereby shall terminate when all the
Loan Document Obligations have been indefeasibly paid in full.

         (b) In connection with any termination or release pursuant to paragraph
(a) the Administrative Agent shall execute and deliver to the Grantor, at the
Grantor's expense, all documents that the Grantor shall reasonably request to
evidence such termination or release. Any execution and delivery of documents
pursuant to this Section 7.15 shall be without recourse to or warranty by the
Administrative Agent.

         SECTION 7.16. Right of Setoff. If an Event of Default shall have
occurred and be continuing, 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 obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of any
Guarantor against any of and all its obligations now or hereafter existing under
this Agreement held by such Lender, irrespective of whether or not such Lender
shall have made any demand under this Agreement and although such obligations
may be unmatured. The rights of each Lender under this Section are in addition
to other rights and remedies (including other rights of setoff) which such
Lender may have.

                                       16

         IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the day and year first above written.
