for such Eurodollar Rate Borrowing for such Interest Period.

For purposes of determining the Applicable Margin, with respect to the debt
ratings criteria: (i) if neither Moody's nor S&P shall have in effect a rating
for Index Debt (other than by reason of the circumstances referred to in the
last sentence of this definition), then both such rating agencies will be deemed
to have established ratings for Index Debt in Category 6; (ii) if only one of
Moody's or S&P shall have in effect a rating for Index Debt, the Company and the
Lenders will negotiate in good faith to agree upon another rating agency to be
substituted by an agreement for the rating agency which shall not have a rating
in effect, and in the absence of such agreement the Applicable Margin will be
determined by reference to the available rating; (iii) except as expressly
provided in the above table, if the ratings established by Moody's and S&P shall
differ by (x) one Category, the Applicable Margin shall be determined by
reference to the numerically lower Category, and (y) two or more Categories the
Applicable Margin shall be determined by reference to the numerical Category
which is one less than the numerically highest such Category (for example, if
the rating from S&P is in Category 2 and the rating from Moody's is in Category
6, the Applicable Margin shall be determined by reference to Category 5); and
(iv) if any rating established by Moody's or S&P shall be changed (other than as
a result of a change in the rating system of either Moody's or S&P), such change
shall be effective as of the date on which such change is first announced by the
rating agency making such change. If the rating system of either Moody's or S&P
shall change prior to the payment in full of the Obligation and the cancellation
of all commitments to lend hereunder, the Company and the Lenders shall
negotiate in good faith to amend the references to specific ratings in this
definition to reflect such changed rating system. If both Moody's and S&P shall
cease to be in the business of rating corporate debt obligations, the Company
and the Lenders shall negotiate in good faith to agree upon a substitute rating
agency and to amend the references to specific ratings in this

definition to reflect the ratings used by such substitute rating agency, and the
Applicable Margin shall continue to be based upon the ratings Category in effect
immediately prior to such event until such agreement on a substitute rating
agency is reached.

         "ARRANGER" means Credit Lyonnais New York Branch and its successors and
assigns.

         "ATTRIBUTABLE OBLIGATION" of any Person means, with respect to any Sale
and Lease-Back Transaction of such Person as of any particular time, the present
value at such time discounted at the rate of interest implicit in the terms of
the lease of the obligations of the lessee under such lease for net rental
payments during the remaining term of the lease (including any period for which
such lease has been extended or may, at the option of such Person, be extended).

         "BANKRUPTCY CODE" means Title 11 of the United States Code entitled
"Bankruptcy" as now or hereinafter in effect, or any successor thereto.

         "BASE RATE" means, for any day, the rate per annum equal to the higher
of (a) the Federal Funds Rate for such day plus one-half of one percent (.5%) or
(b) the Prime Rate for such day. Any change in the Base Rate due to a change in
the Prime Rate or the Federal Funds Rate shall be effective on the effective
date of such change in the Prime Rate or Federal Funds Rate.

         "BASE RATE BORROWING" means a Borrowing bearing interest at the sum of
the Base Rate plus the Applicable Margin for Base Rate Borrowings.

         "BORROWING" means any amount disbursed (a) by one or more Lenders to
the Company under the Loan Papers, whether such amount constitutes an original
disbursement of funds or the continuation of an amount outstanding or (b) by any
Lender in accordance with, and to satisfy the obligations under, any Loan Paper.

         "BORROWING DATE" is defined in Section 2.3(a).

         "BUSINESS DAY" means (a) for all purposes, any day other than Saturday,
Sunday, and any other day on which commercial banking institutions are required
or authorized by Law to be closed in New York, New York, and (b) in addition to

Facility not to exceed such Lender's Committed Sum under the Term Facility;
provided that (i) each such Borrowing must occur on a Business Day during the

$50,000,000 or a greater integral multiple of $1,000,000 (or the remaining

Borrowing to be made from such Lender may from time to time be made from its

that if any Designated Lender elects not to, or fails to, make any such
Borrowing available, its Designating Lender hereby agrees that it shall make
such Borrowing available pursuant to the terms hereof. Any Borrowing actually
funded by a Designated Lender shall constitute a utilization of the Designating
Lender's Pro Rata Part of the Commitment for all purposes hereunder.

         2.2. Termination of Commitments. Without premium or penalty, and upon
giving not less than three Business Days prior written and irrevocable notice to

                                       14
<PAGE>   19

receipt of such notice of termination or reduction, Administrative Agent shall
notify each Lender of the proposed cancellation or reduction. Such termination
or partial reduction of the Commitment shall be effective on the Business Day
specified in Borrower's notice (which date must be during the Commitment Period
and at least three (3) Business Days after the Company's delivery of such
notice). In the event that the Commitment is reduced to zero at a time when

extent specified in Section 12.14, and all commitment fees and other fees then
earned and unpaid hereunder and all other amounts of the Obligation relating to
the Term Facility then due and owing shall be immediately due and payable,
without notice or demand by Administrative Agent or any Lender.

         2.3. Borrowing Procedure. The following procedures apply to Borrowings:

                  (a) Each Borrowing shall be made on the Company's notice (a
         "Notice of Borrowing," substantially in the form of Exhibit B-1) to
         Administrative Agent requesting that Lenders fund a Borrowing on a
         certain date (the "Borrowing Date"), which notice (i) shall be
         irrevocable and binding on the Company, (ii) shall specify the
         Borrowing Date, amount, Type, and (for a Borrowing comprised of
         Eurodollar Rate Borrowings) Interest Period, and (iii) must be received
         by Administrative Agent no later than 11:00 a.m. New York, New York
         time on the third (3rd) Business Day preceding the Borrowing Date for
         any Eurodollar Rate Borrowing or on the Borrowing Date for any Base
         Rate Borrowing. Administrative Agent shall timely notify each Lender
         with respect to each Notice of Borrowing.

                  (b) Each Lender shall remit its Pro Rata Part of each
         requested Borrowing to Administrative Agent's principal office in New
         York, New York, in funds which are or will be available for immediate
         use by Administrative Agent by 1:00 p.m. New York, New York time on the
         Borrowing Date therefor. Subject to receipt of such funds,
         Administrative Agent shall (unless to its actual knowledge any of the
         conditions precedent therefor have not been satisfied by the Company or
         waived by Determining Lenders) make such funds available to the Company
         by causing such funds to be deposited to the Company's account as
         designated to Administrative Agent by the Company. Notwithstanding the
         foregoing, unless Administrative Agent shall have been notified by a
         Lender prior to a Borrowing Date that such Lender does not intend to
         make available to Administrative Agent such Lender's Pro Rata Part of
         the applicable Borrowing, Administrative Agent may assume that such
         Lender has made such proceeds available to Administrative Agent on such
         date, as required herein, and Administrative Agent may (unless to its
         actual knowledge any of the conditions precedent therefor have not been
         satisfied by the Company or waived by Determining Lenders), in reliance
         upon such assumption (but shall not be required to), make available to
         the Company a corresponding amount in accordance with the foregoing
         terms, but, if such corresponding amount is not in fact made available
         to Administrative Agent by such Lender on such Borrowing Date,
         Administrative Agent shall be entitled to recover such corresponding
         amount on demand (i) from such Lender, together with interest at the
         Federal Funds Rate during the period commencing on the date such
         corresponding amount was made available to the Company and ending on
         (but excluding) the date Administrative Agent recovers such
         corresponding amount from such Lender, or (ii) if such Lender fails to
         pay such corresponding amount forthwith upon such demand, then from the
         Company, together with interest at a rate per annum equal to the
         applicable rate for such Borrowing during the period commencing on such
         Borrowing Date and ending on (but excluding) the date Administrative
         Agent recovers such corresponding amount from the Company. No Lender
         shall be responsible for the failure of any other Lender to make its
         Pro Rata Part of any Borrowing.

SECTION 3 TERMS OF PAYMENT

         3.1 Loan Accounts, Notes, and Payments.

                  (a) Principal Debt shall be evidenced by the Term Notes, one
         payable to each Lender in the stated principal amount of its Committed
         Sum.

                  (b) The Principal Debt owed to each Lender shall be further
         evidenced by one or more loan accounts or records maintained by such
         Lender in the ordinary course of business. The loan accounts or records
         maintained by the Administrative Agent (including, without limitation,
         the Register) and each Lender shall be conclusive evidence absent
         manifest error of the amount of the Borrowings made by the Company from
         each Lender under the Term Facility and the interest and principal
         payments thereon. Any failure to so record or any error in doing so
         shall not, however, limit or otherwise affect the obligation of the
         Company under the Loan Papers to pay any amount owing with respect to
         the Obligation.

                  (c) Each payment or prepayment on the Obligation is due and
         must be paid at Administrative Agent's principal office in New York,
         New York in funds which are or will be available for immediate use by
         Administrative Agent by 1:00 p.m., New York, New York time on the day
         due. Payments made after 1:00 p.m., New York, New York time, shall be
         deemed made on the Business Day next following. Administrative Agent
         shall pay to each Lender any payment or prepayment to which such Lender
         is entitled hereunder on the same day Administrative Agent shall have
         received the same from the Company; provided such payment or prepayment
         is received by Administrative Agent prior to 1:00 p.m. New York, New
         York time and otherwise before 1:00 p.m. New York, New York time on the
         Business Day next following. If and to the extent Administrative Agent
         shall not make such payments to Lenders when due as set forth in the
         preceding sentence, such unpaid amounts shall accrue interest, payable
         by Administrative Agent, at the Federal Funds Rate from the due date
         until (but not including) the date on which Administrative Agent makes
         such payments to Lenders.

         3.2 Interest and Principal Payments.

                  (a) Interest on each Eurodollar Rate Borrowing shall be due
         and payable as it accrues on the last day of its respective Interest
         Period and on the Maturity Date, as applicable; provided that if any
         Interest Period is a period greater than three (3) months, then accrued
         interest shall also be due and payable on the date three (3) months
         after the commencement of such Interest Period. Interest on each Base
         Rate Borrowing shall be due and payable as it accrues on the last day
         of each calendar month, and on the Maturity Date.

                  (b) The Commitment shall be permanently canceled and reduced
         to $0 at the end of the Commitment Period. The Company shall pay on the
         Maturity Date all outstanding Principal Debt, together with all accrued
         and unpaid interest and fees.

                  (c) On any date of determination, if the Commitment Usage
         exceeds the Commitment then in effect then the Company shall make a
         mandatory prepayment of the Principal Debt in at least the amount of
         such excess, together with (i) all accrued and unpaid interest on the
         principal amount so prepaid and (ii) any Consequential Loss arising as
         a result thereof.

                  (d) After giving Administrative Agent advance written notice
         of the intent to prepay, the Company may voluntarily prepay all or any
         part of the Principal Debt from time to time and


                                                             TERM LOAN AGREEMENT

                                       16
<PAGE>   21

         at any time, in whole or in part, without premium or penalty; provided
         that: (i) such notice must be received by Administrative Agent by 1:00
         p.m. New York, New York time on (A) the third Business Day preceding
         the date of prepayment of a Eurodollar Rate Borrowing, and (B) one
         Business Day preceding the date of prepayment of a Base Rate Borrowing;
         (ii) each such partial prepayment must be in a minimum amount of at
         least $5,000,000 or a greater integral multiple of $1,000,000 thereof
         (if a Eurodollar Rate Borrowing or a Base Rate Borrowing); and (iii)
         all accrued interest on the Obligation to be prepaid must also be paid
         in full, to the date of such prepayment. Each notice of prepayment
         shall specify the prepayment date, the Type of Borrowing(s) and
         amount(s) of such Borrowing(s) to be prepaid and shall constitute a
         binding obligation of the Company to make a prepayment on the date
         stated therein.

         3.3 Interest Options. Except where specifically otherwise provided,
Borrowings shall bear interest at a rate per annum equal to the lesser of (a) as
to the respective Type of Borrowing (as designated by the Company in accordance
with this Agreement), the Base Rate plus the Applicable Margin for Base Rate
Borrowings, the Adjusted Eurodollar Rate plus the Applicable Margin for
Eurodollar Rate Borrowings, as the case may be, and (b) the Maximum Rate. Each
change in the Base Rate or the Maximum Rate subject to the terms of this
Agreement, will become effective, without notice to the Company or any other
Person, upon the effective date of such change.

         3.4. Quotation of Rates. It is hereby acknowledged that a Responsible
Officer or other appropriately designated officer of the Company may call
Administrative Agent on or before the date on which a Notice of Borrowing is to
be delivered by the Company in order to receive an indication of the rates then
in effect, but such indicated rates shall neither be binding upon Administrative
Agent or Lenders nor affect the rate of interest which thereafter is actually in
effect when the Notice of Borrowing is given.

         3.5 Default Rate. At the option of Determining Lenders and to the
extent permitted by Law, all past-due Principal Debt and accrued interest
thereon shall bear interest from maturity (whether stated or by acceleration) at
the Default Rate until paid, regardless whether such payment is made before or
after entry of a judgment.

         3.6 Interest Recapture. If the designated rate applicable to any
Borrowing exceeds the Maximum Rate, the rate of interest on such Borrowing shall
be limited to the Maximum Rate, but any subsequent reductions in such designated
rate shall not reduce the rate of interest thereon below the Maximum Rate until
the total amount of interest accrued thereon equals the amount of interest which
would have accrued thereon if such designated rate had at all times been in
effect. In the event that at maturity (stated or by acceleration), or at final
payment of the Principal Debt, the total amount of interest paid or accrued is
less than the amount of interest which would have accrued if such designated
rates had at all times been in effect, then, at such time and to the extent
permitted by Law, the Company shall pay an amount equal to the difference, if
any, by which (a) the lesser of the amount of interest which would have accrued
if such designated rates had at all times been in effect and the amount of
interest which would have accrued if the Maximum Rate had at all times been in
effect, exceeds (b) the amount of interest actually paid or accrued on the
Principal Debt.

                  (a) All payments of interest shall be calculated on the basis
         of actual number of days (including the first day but excluding the
         last day) elapsed but computed as if each calendar year consisted of
         (i) 360 days in the case of a Eurodollar Rate Borrowing or a Base Rate
         Borrowing calculated with reference to the Federal Funds Rate (unless
         such calculation would result in the interest on the Borrowings
         exceeding the Maximum Rate in which event such interest shall be
         calculated on the basis of a year of 365 or 366 days, as the case may
         be) and (ii) 365 or 366 days, as the case may be, in the case of a Base
         Rate Borrowing calculated with reference to the Prime Rate. All
         interest rate determinations and calculations by Administrative Agent
         shall be conclusive and binding absent manifest error.

                  (b) The provisions of this Agreement relating to calculation
         of the Base Rate and the Adjusted Eurodollar Rate are included only for
         the purpose of determining the rate of interest or other amounts to be
         paid hereunder that are based upon such rate.

         3.8 Maximum Rate. Regardless of any provision contained in any Loan
Paper, no Lender shall ever be entitled to contract for, charge, take, reserve,
receive, or apply, as interest on the Obligation, or any part thereof, any
amount in excess of the Maximum Rate, and, if a Lender ever does so, then such
excess shall be deemed a partial prepayment of principal and treated hereunder
as such and any remaining excess shall be refunded to the Company. In
determining if the interest paid or payable exceeds the Maximum Rate, the
Company and Lenders shall, to the maximum extent permitted under applicable Law,
(a) treat all Borrowings as but a single extension of credit (and Lenders and
the Company agree that such is the case and that provision herein for multiple
Borrowings is for convenience only), (b) characterize any nonprincipal payment
otherwise payable under the Loan Papers as an expense, fee, or premium, rather
than as interest, (c) exclude voluntary prepayments and the effects thereof, and
(d) amortize, prorate, allocate, and spread the total amount of interest
throughout the entire contemplated term of the Obligation; provided that, if the
Obligation is paid and performed in full prior to the end of the full
contemplated term thereof, and if the interest received for the actual period of
existence thereof exceeds the Maximum Amount, Lenders shall refund such excess,
and, in such event, Lenders shall not, to the extent permitted by Law, be
subject to any penalties provided by any Laws for contracting for, charging,
taking, reserving, or receiving interest in excess of the Maximum Amount.

         3.9 Interest Periods. When the Company requests any Eurodollar Rate
Borrowing, the Company may elect the interest period (each an "Interest Period")
applicable thereto, which shall be, at the Company's option, in respect of any
Eurodollar Rate Borrowing, one, two, three, or six months; provided, however,
that: (a) the initial Interest Period for a Eurodollar Rate Borrowing shall
commence on the date of such Borrowing (including the date of any conversion
thereto), and each Interest Period occurring thereafter in respect of such
Borrowing shall commence on the day on which the next preceding Interest Period
applicable thereto expires; (b) if any Interest Period for a Eurodollar Rate
Borrowing begins on a day for which there is no numerically corresponding
Business Day in the calendar month at the end of such Interest Period, such
Interest Period shall end on the next Business Day immediately following what
otherwise would have been such numerically corresponding day in the calendar
month at the end of such Interest Period (unless such date would be in a
different calendar month from what would have been the month at the end of such
Interest Period, or unless there is no numerically corresponding day in the
calendar month at the end of the Interest Period; whereupon, such Interest
Period shall end on the last Business Day in the calendar month at the end of
such Interest Period); (c) no Interest Period may be chosen with respect to any
portion of the Principal Debt which would extend beyond the scheduled repayment
date (including any dates on which mandatory prepayments are required to be
made) for such portion of the Principal Debt; and (d) no more than an aggregate
of six (6) Interest Periods shall be in effect at one time.


                                                             TERM LOAN AGREEMENT

                                       18
<PAGE>   23

         3.10 Conversions. The Company may (a) convert a Eurodollar Rate
Borrowing on the last day of an Interest Period to a Base Rate Borrowing, (b)
convert a Base Rate Borrowing at any time to a Eurodollar Rate Borrowing, and
(c) elect a new Interest Period (in the case of a Eurodollar Rate Borrowing), by
giving notice (a "Notice of Conversion," substantially in the form of Exhibit
B-2) of such intent no later than 11:00 a.m. New York, New York, time on the
third Business Day prior to the date of conversion or the last day of the
Interest Period, as the case may be (in the case of a conversion to a Eurodollar
Rate Borrowing or an election of a new Interest Period), and no later than 11:00
a.m. New York, New York time one Business Day prior to the last day of the
Interest Period (in the case of a conversion to a Base Rate Borrowing); provided
that the principal amount converted to, or continued as, a Eurodollar Rate
Borrowing shall be in an amount not less than $5,000,000 or a greater integral
multiple of $1,000,000. Administrative Agent shall timely notify each Lender
with respect to each Notice of Conversion. Absent the Company's Notice of
Conversion or election of a new Interest Period, a Eurodollar Rate Borrowing
shall be deemed converted to a Base Rate Borrowing effective as of the
expiration of the Interest Period applicable thereto. No Eurodollar Rate
Borrowing may be either made or continued as a Eurodollar Rate Borrowing, and no
Base Rate Borrowing may be converted to a Eurodollar Rate Borrowing, if the
interest rate for such Eurodollar Rate Borrowing would exceed the Maximum Rate.

         3.11 Order of Application.

                  (a) So long as no Default or Potential Default has occurred
         and is continuing, payments and prepayments of the Obligation shall be
         applied in the order and manner as the Company may direct; provided
         that, each such payment or prepayment (other than payments of fees
         payable solely to any Agent or a specific Lender) shall be allocated
         among Lenders in proportion to their respective Pro Rata Parts
         appropriate for the Term Facility in respect of which such payments
         were made.

                  (b) If a Default or Potential Default has occurred and is
         continuing (or if the Company fails to give directions as permitted
         under Section 3.11(a)), any payment or prepayment (including proceeds
         from the exercise of any Rights) shall be applied in the following
         order: (i) to the ratable payment of all fees and expenses for which
         Agents or Lenders have not been paid or reimbursed in accordance with
         the Loan Papers (as used in this Section 3.11(b), a "ratable payment"
         for any Lender or Agents shall be, on any date of determination, that
         proportion which the portion of the total fees and indemnities owed to
         such Lender or Agents bears to the total aggregate fees and indemnities
         owed to all Lenders or Agents on such date of determination); (ii) to
         the Pro Rata payment of all accrued and unpaid interest on the
         Principal Debt; (iii) to the Pro Rata payment of the remaining
         Principal Debt in such order as Determining Lenders may elect (provided
         that, Determining Lenders will apply such proceeds in an order that
         will minimize any Consequential Loss); and (vii) to the payment of the
         remaining Obligation in the order and manner Determining Lenders deem
         appropriate.

         3.12 Sharing of Payments, Etc.. If any Lender shall obtain any payment
(whether voluntary, involuntary, or otherwise, including, without limitation, as
a result of exercising its Rights under Section 3.13) which is in excess of its
ratable share of any such payment, such Lender shall purchase from the other
Lenders such participations as shall be necessary to cause such purchasing
Lender to share the excess payment ratably with each of them; provided, however,
that if all or any portion of such excess payment is thereafter recovered from
such purchasing Lender, the purchase shall be rescinded and the purchase price
restored to the extent of such recovery. the Company agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section may to
the fullest extent permitted by Law, exercise all of its Rights of payment
(including the Right of offset) with respect to such


                                                             TERM LOAN AGREEMENT

                                       19
<PAGE>   24

participation as fully as if such Lender were the direct creditor of the Company
in the amount of such participation.

         3.13 Offset. Upon the occurrence and during the continuance of a
Default, each Lender shall be entitled to exercise (for the benefit of all
Lenders in accordance with Section 3.12) the Rights of offset and/or banker's
Lien against each and every account and other property, or any interest therein,
which the Company may now or hereafter have with, or which is now or hereafter
in the possession of, such Lender to the extent of the full amount of the
Obligation owed to such Lender.

         3.14 Booking Borrowings. To the extent permitted by Law, any Lender
may make, carry, or transfer its Borrowings at, to, or for the account of any of
its branch offices or the office of any of its Affiliates; provided that no
Affiliate shall be entitled to receive any greater payment under Section 4 than
the transferor Lender would have been entitled to receive with respect to such
Borrowings.

SECTION 4 CHANGE IN CIRCUMSTANCES.

         4.1 Increased Cost and Reduced Return.

                  (a) If, after the date hereof, the adoption of any applicable
         law, rule, or regulation or any change in any applicable law, rule, or
         regulation, or any change in the interpretation or administration
         thereof by any Governmental Authority, or compliance by any Lender (or
         its Applicable Lending Office) with any request or directive (whether
         or not having the force of law) of any such Governmental Authority:

                           (i) shall subject such Lender (or its Applicable
                  Lending Office) to any Tax or other charge with respect to any
                  Eurodollar Rate Borrowing, its Notes, or its obligation to
                  loan Eurodollar Rate Borrowings, or change the basis of
                  taxation of any amounts payable to such Lender (or its
                  Applicable Lending Office) under this Agreement or its Notes
                  in respect of any Eurodollar Rate Borrowings (other than with
                  respect to taxes imposed on the taxable net income of such
                  Lender by any jurisdiction within which such Lender is
                  incorporated or organized or has its principal office, or
                  within which such Applicable Lending Office is located, or by
                  any other jurisdiction in which such Lender is deemed to be
                  doing business);

                           (ii) shall impose, modify, or deem applicable any
                  reserve, special deposit, assessment, or similar requirement
                  (other than the Reserve Requirement utilized in the
                  determination of the Adjusted Eurodollar Rate) relating to any
                  extensions of credit or other assets of, or any deposits with
                  or other liabilities or commitments of, such Lender (or its
                  Applicable Lending Office), including the commitment of such
                  Lender hereunder; or

                           (iii) shall impose on such Lender (or its Applicable
                  Lending Office) or the London interbank market any other
                  condition affecting this Agreement or its Notes or any of such
                  extensions of credit or liabilities or commitments;

                  and the result of any of the foregoing is to increase the cost
                  to such Lender (or its Applicable Lending Office) of making,
                  converting into, continuing, or maintaining any Eurodollar
                  Rate Borrowings or to reduce any sum received or receivable by
                  such Lender (or its Applicable Lending Office) under this
                  Agreement or its Notes with respect to any Eurodollar Rate
                  Borrowing, then the Company shall pay to such Lender on demand
                  such amount or amounts as will compensate such Lender for such
                  increased cost or reduction


                                                             TERM LOAN AGREEMENT

                                       20
<PAGE>   25

                  as provided in Section 4.1(c) below. If any Lender requests
                  compensation by the Company under this Section 4.1(a), the
                  Company may, by notice to such Lender (with a copy to
                  Administrative Agent), suspend the obligation of such Lender
                  to loan or continue Borrowings of the Type with respect to
                  which such compensation is requested, or to convert Borrowings
                  of any other Type into Borrowings of such Type, until the
                  event or condition giving rise to such request ceases to be in
                  effect (in which case the provisions of Section 4.4 shall be
                  applicable); provided, that such suspension shall not affect
                  the right of such Lender to receive the compensation so
                  requested.

                  (b) If, after the date hereof, any Lender shall have
         determined that the adoption of any applicable Law regarding capital
         adequacy or any change therein or in the interpretation or
         administration thereof by any Governmental Authority charged with the
         interpretation or administration thereof, or any request or directive
         regarding capital adequacy (whether or not having the force of law) of
         any such Governmental Authority has or would have 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 to a level below that which such Lender or such
         corporation could have achieved but for such adoption, change, request,
         or directive (taking into consideration its policies with respect to
         capital adequacy), then from time to time upon demand the Company shall
         pay to such Lender such additional amount or amounts as will compensate
         such Lender for such reduction; provided, however, that the Company
         shall not be obligated to pay any such additional amount or amounts
         incurred or accruing more than ninety (90) days prior to the date on
         which the affected Lender gives written notice thereof in accordance
         with Section 4.1(c) below.

                  (c) Each Lender shall promptly notify the Company and
         Administrative Agent of any event of which it has knowledge, occurring
         after the date hereof, which will entitle such Lender to compensation
         pursuant to this Section and will designate a different Applicable
         Lending Office if such designation will avoid the need for, or reduce
         the amount of, such compensation and will not, in the judgment of such
         Lender, be otherwise disadvantageous to it. Any Lender claiming
         compensation under this Section shall furnish to the Company and
         Administrative Agent a statement setting forth in reasonable detail the
         additional amount or amounts to be paid hereunder which shall be
         presumed correct in the absence of manifest error. In determining such
         amount, such Lender may use any reasonable averaging and attribution
         methods.

         4.2 Limitation on Types of Loans. If on or prior to the first day of
any Interest Period for any Eurodollar Rate Borrowing:

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

                  (b) Determining Lenders determine (which determination shall
         be conclusive) and notify Administrative Agent that the Adjusted
         Eurodollar Rate will not adequately and fairly reflect the cost to the
         Lenders of funding Eurodollar Rate Borrowings for such Interest Period;

         then Administrative Agent shall give the Company prompt notice thereof
         specifying the relevant amounts or periods, and so long as such
         condition remains in effect, the Lenders shall be under no obligation
         to fund additional Eurodollar Rate Borrowings, continue Eurodollar Rate
         Borrowings, or to convert Base Rate Borrowings into Eurodollar Rate
         Borrowings, and the Company shall, on the last day(s) of the then
         current Interest Period(s) for the outstanding Eurodollar Rate


                                                             TERM LOAN AGREEMENT

                                       21
<PAGE>   26

         Borrowings, either prepay such Borrowings or convert such Borrowings
         into Base Rate Borrowings in accordance with the terms of this
         Agreement.

         4.3 Illegality. Notwithstanding any other provision of this Agreement,
in the event that it becomes unlawful for any Lender or its Applicable Lending
Office to make, maintain, or fund Eurodollar Rate Borrowings hereunder, then
such Lender shall promptly notify the Company thereof and such Lender's
obligation to make or continue Eurodollar Rate Borrowings and to convert other
Base Rate Borrowings into Eurodollar Rate Borrowings shall be suspended until
such time as such Lender may again make, maintain, and fund Eurodollar Rate
Borrowings (in which case the provisions of Section 4.4 shall be applicable).

         4.4 Treatment of Affected Loans. If the obligation of any Lender to
fund Eurodollar Rate Borrowings or to continue, or to convert Base Rate
Borrowings into Eurodollar Rate Borrowings, shall be suspended pursuant to
Sections 4.1, 4.2, or 4.3 hereof, such Lender's Eurodollar Rate Borrowings shall
be automatically converted into Base Rate Borrowings on the last day(s) of the
then current Interest Period(s) for Eurodollar Rate Borrowings (or, in the case
of a conversion required by Section 4.3 hereof, on such earlier date as such
Lender may specify to the Company with a copy to Administrative Agent) and,
unless and until such Lender gives notice as provided below that the
circumstances specified in Sections 4.1, 4.2, or 4.3 hereof that gave rise to
such conversion no longer exist:

                  (a) to the extent that such Lender's Eurodollar Rate
         Borrowings have been so converted, all payments and prepayments of
         principal that would otherwise be applied to such Lender's Eurodollar
         Rate Borrowings shall be applied instead to its Base Rate Borrowings;
         and

                  (b) all Borrowings that would otherwise be made or continued
         by such Lender as Eurodollar Rate Borrowings shall be made or continued
         instead as Base Rate Borrowings, and all Borrowings of such Lender that
         would otherwise be converted into Eurodollar Rate Borrowings shall be
         converted instead into (or shall remain as) Base Rate Borrowings.

If such Lender gives notice to the Company (with a copy to Administrative Agent)
that the circumstances specified in Sections 4.1, 4.2, or 4.3 hereof that gave
rise to the conversion of such Lender's Eurodollar Rate Borrowings pursuant to
this Section 4.4 no longer exist (which such Lender agrees to do promptly upon
such circumstances ceasing to exist) at a time when Eurodollar Rate Borrowings
made by other Lenders are outstanding, such Lender's Base Rate Borrowings shall
be automatically converted, on the first day(s) of the next succeeding Interest
Period(s) for such outstanding Eurodollar Rate Borrowings, to the extent
necessary so that, after giving effect thereto, all Eurodollar Rate Borrowings
held by the Lenders and by such Lender are held Pro Rata (as to principal
amounts, Types, and Interest Periods).

         4.5 Compensation; Replacement of Lenders.

                  (a) Upon the request of any Lender, the Company shall pay to
         such Lender such amount or amounts as shall be sufficient (in the
         reasonable opinion of such Lender) to compensate it for any
         Consequential Loss; provided that, in each case, the Person claiming
         such Consequential Loss has furnished the Company with a reasonably
         detailed statement of such loss, which statement shall be conclusive in
         the absence of manifest error.

                  (b) If any Lender requests compensation under Sections 4.1 or
         if the Company is required to pay additional amounts to or for the
         account of any Lender pursuant to Section 4.6 (collectively,
         "Additional Amounts"), then the Company may, at its sole expense and
         effort, upon written notice to such Lender and Administrative Agent,
         require such Lender to assign and


                                                             TERM LOAN AGREEMENT

                                       22
<PAGE>   27

         delegate, without recourse, all its interests, Rights, and obligations
         under this Agreement and the other Loan Papers to an Eligible Assignee
         that shall assume such obligations; provided that, (i) the Company
         shall have received the prior written consent of Administrative Agent
         to any such assignment; (ii) such Lender shall have received payment
         from the Company of any Additional Amounts owed to such Lender by the
         Company for periods prior to the replacement of such Lender and any
         costs incurred as a result of such replacement of a Lender; (iii) such
         assignment will result in reduction or elimination of the Additional
         Amounts; and (iv) such assignment and acceptance shall be made in
         accordance with, and subject to the requirements and restrictions
         contained in, Section 12.13(b), other than the restrictions imposed by
         Section 12.13(b)(iv). A Lender shall not be required to make any such
         assignment and delegation if, prior thereto, as a result of a waiver by
         such Lender or otherwise, the circumstances entitling such Borrowing to
         require such assignment and delegation cease to apply.

         4.6 Taxes.

                  (a) Any and all payments by the Company to or for the account
         of any Lender or Administrative Agent hereunder or under any other Loan
         Paper shall be made free and clear of and without deduction for any and
         all present or future Taxes, excluding, in the case of each Lender and
         Administrative Agent, Taxes imposed on its income and franchise Taxes
         imposed on it by any jurisdiction within which such Lender (or its
         Applicable Lending Office) or Administrative Agent (as the case may be)
         is incorporated or organized, or any political subdivision thereof, or
         by any other jurisdiction in which such Lender or Administrative Agent,
         as the case may be, is deemed to be doing business under the Tax Laws
         thereof (all such Non-Excluded Taxes referred to as "Non-Excluded
         Taxes"). If the Company shall be required by law to deduct any
         Non-Excluded Taxes from or in respect of any sum payable under this
         Agreement or any other Loan Paper to any Lender or Administrative
         Agent, (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 4.6) such Lender or
         Administrative Agent receives an amount equal to the sum it would have
         received had no such deductions been made, (ii) the Company shall make
         such deductions, (iii) the Company shall pay the full amount deducted
         to the relevant taxation authority or other authority in accordance
         with applicable law, and (iv) within thirty (30) days after the date of
         any payment of Non-Excluded Taxes, the Company shall furnish to
         Administrative Agent, at its address listed in Schedule 2.1, the
         original or a certified copy of a receipt evidencing payment thereof.

                  (b) In addition, the Company agrees to pay any and all present
         or future stamp or documentary taxes or charges or similar levies which
         arise from any payment made under this Agreement or any other Loan
         Paper or from the execution or delivery of, or otherwise with respect
         to, this Agreement or any other Loan Paper (hereinafter referred to as
         "Other Taxes").

                  (c) THE COMPANY AGREES TO INDEMNIFY EACH LENDER AND
         ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF NON-EXCLUDED TAXES THAT
         SHOULD HAVE BEEN WITHHELD BY THE COMPANY AND OTHER TAXES (INCLUDING,
         WITHOUT LIMITATION, ANY NON-EXCLUDED TAXES THAT SHOULD HAVE BEEN
         WITHHELD BY THE COMPANY OR OTHER TAXES IMPOSED OR ASSERTED BY ANY
         JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 4.6) PAID BY SUCH
         LENDER OR ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY
         (INCLUDING PENALTIES, INTEREST, AND EXPENSES) ARISING THEREFROM OR WITH
         RESPECT THERETO.

                  (d) Each Lender organized under the laws of a jurisdiction
         outside the United States, on or prior to the date of its execution and
         delivery of this Agreement in the case of each Lender


                                                             TERM LOAN AGREEMENT

         listed on the signature pages hereof and on or prior to the date on
         which it becomes a Lender in the case of each other Lender, and from
         time to time thereafter if requested in writing by the Company or
         Administrative Agent (but only so long as such Lender remains lawfully
         able to do so), shall provide the Company and Administrative Agent with
         (i) two duly completed, accurate, and signed copies of Internal Revenue
         Service Form 1001 or 4224, as appropriate, or any successor form
         prescribed by the Internal Revenue Service, certifying that such Lender
         is entitled to benefits under an income tax treaty to which the United
         States is a party which reduces the rate of withholding tax on payments
         of interest or certifying that the income receivable pursuant to this
         Agreement is effectively connected with the conduct of a trade or
         business in the United States, (ii) a duly completed, accurate and
         signed Internal Revenue Service Form W-8 or W-9, as appropriate, or any
         successor form prescribed by the Internal Revenue Service, and (iii)
         any other form or certificate required by any taxing authority
         (including any certificate required by Sections 871(h) and 881(c) of
         the Internal Revenue Code), certifying that such Lender is entitled to
         an exemption from or a reduced rate of tax on payments pursuant to this
         Agreement or any of the other Loan Papers.

                  (e) For any period with respect to which a Lender has failed
         to provide the Company and Administrative Agent with the appropriate
         form pursuant to Section 4.6(d) (unless such failure is due to a change
         in Law, other than any change in the nature of an anti-treaty shopping
         or limitation on benefits or similar provision, occurring subsequent to
         the date on which a form originally was required to be provided), such
         Lender shall not be entitled to indemnification under Section 4.6(a) or
         4.6(b) with respect to Taxes imposed by the United States; provided,
         however, that should a Lender, which is otherwise exempt from or
         subject to a reduced rate of withholding tax, become subject to Taxes
         because of its failure to deliver a form required hereunder, the
         Company shall take such steps as such Lender shall reasonably request
         to assist such Lender to recover such Taxes.

                  (f) If the Company is required to pay additional amounts to or
         for the account of any Lender pursuant to this Section 4.6, then such
         Lender will agree to use reasonable efforts to change the jurisdiction
         of its Applicable Lending Office so as to eliminate or reduce any such
         additional payment which may thereafter accrue if such change, in the
         judgment of such Lender, is not otherwise disadvantageous to such
         Lender.

                  (g) Without prejudice to the survival of any other agreement
         of the Company hereunder, the agreements and obligations of the Company
         contained in this Section 4.6 shall survive the termination of the
         Commitment and the payment in full of the Notes.

         5.1 Treatment of Fees. Except as otherwise provided by Law, the fees

SECTION 6 CONDITIONS PRECEDENT

         6.1 Conditions Precedent to Closing. This Agreement shall not become
effective unless Administrative Agent has received all of the agreements,
documents, instruments, and other items described on Schedule 6.1.

         6.2 Conditions Precedent to Each Borrowing. In addition to the
conditions stated in Section 6.1, Lenders will not be obligated to fund (as
opposed to continue or convert) any Borrowing, unless on the date of such
Borrowing (and after giving effect thereto): (a) Administrative Agent shall have
timely received therefor a Notice of Borrowing; (b) all of the representations
and warranties of the Company set forth in the Loan Papers are true and correct
in all material respects on and as of the date of Borrowing as if made on and as
of such date; (c) no Default or Potential Default shall have occurred and be
continuing on such date or after giving effect to the Borrowing requested; and
(d) the funding of such Borrowings is permitted by Law. Each Notice of Borrowing
delivered to Administrative Agent shall constitute the representation and

(b), (c) and (d) above are true and correct in all respects. Each condition
precedent in this Agreement is material to the transactions contemplated in this
Agreement, and time is of the essence in respect of each thereof. Subject to the
prior approval of Determining Lenders, Lenders may fund any Borrowing without
all conditions being satisfied, but, to the extent permitted by Law, the same
shall not be deemed to be a waiver of the requirement that each such condition
precedent be satisfied as a prerequisite for any subsequent funding or issuance,
unless Determining Lenders specifically waive each such item in writing.

SECTION 7 REPRESENTATIONS AND WARRANTIES. To induce Lenders to enter into this
Agreement and to make the loans herein provided for, the Company hereby

of


                                                             TERM LOAN AGREEMENT

                                       32
<PAGE>   37

such failure, or (ii) any term, covenant or agreement contained in this

         9.4 Default Under Other Debt. The Company or any of its Subsidiaries

period, if any, specified in the agreement or instrument relating to such Debt;
or any other event shall occur or condition shall exist under any agreement or
instrument relating to any such Debt and shall continue after the applicable
grace period, if any, specified in such agreement or instrument, if the effect
of such event or condition is to accelerate, or to permit the acceleration of,
the maturity of such Debt; or any such Debt shall be declared to be due and
payable, or required to be prepaid (other than by a regularly scheduled required
prepayment or as a result of the giving of notice of a voluntary prepayment),
prior to the stated maturity thereof; provided, however, that the provisions of

<PAGE>   38

                  (c) The Company or any ERISA Affiliate shall have been
         notified by the sponsor of a Multiemployer Plan that such Multiemployer
         Plan is in reorganization or is being terminated, within the meaning of

SECTION 10 RIGHTS AND REMEDIES

         10.1 Remedies Upon Default.

                  (a) If a Default exists under Section 9.5, the commitment to
         extend credit hereunder shall automatically terminate and the entire
         unpaid balance of the Obligation under the Term Facility shall
         automatically become due and payable without any action or notice of
         any kind whatsoever.

                  (b) If any Default exists, Administrative Agent may (and,
         subject to the terms of Section 11, shall upon the request of
         Determining Lenders) or Determining Lenders may, do any one or more of
         the following: (i) if the maturity of the Obligation under the Term
         Facility has not already been accelerated under Section 10.1(a),
         declare the entire unpaid balance of the Obligation, or any part
         thereof, immediately due and payable, whereupon it shall be due and
         payable; (ii) terminate the commitments of Lenders to extend credit
         hereunder; (iii) reduce any claim to judgment; (iv) to the extent
         permitted by Law, exercise (or request each Lender to, and each Lender
         shall be entitled to, exercise) the Rights of offset or banker's Lien
         against the interest of the Company in and to every account and other
         property of the Company which are in the possession of Administrative
         Agent or any Lender to the extent of the full amount of the Obligation
         (to the extent permitted by Law, the Company being deemed directly
         obligated to each Lender in the full amount of the Obligation for such
         purposes); and (v) exercise any and all other legal or equitable Rights
         afforded by the Loan Papers, the Laws of the State of New York, or any
         other applicable jurisdiction as Administrative Agent shall deem
         appropriate, or otherwise, including, but not limited to, the Right to
         bring suit or other proceedings before any Governmental Authority
         either for specific performance of any covenant or condition contained
         in any of the Loan Papers or in aid of the exercise of any Right
         granted to Administrative Agent or any Lender in any of the Loan
         Papers.

         10.2 The Company Waivers. To the extent permitted by Law, the Company
hereby waives presentment and demand for payment, protest, notice of intention
to accelerate, notice of acceleration, and notice of protest and nonpayment, and
agrees that its liability with respect to the Obligation (or any part thereof),
shall not be affected by any renewal or extension in the time of payment of the
Obligation (or any part thereof), by any indulgence, or by any release or change
in any security for the payment of the Obligation (or any part thereof).

         10.3 Performance by Administrative Agent. If any covenant, duty, or
agreement of the Company is not performed in accordance with the terms of the
Loan Papers, after the occurrence and during the continuance of a Default,
Administrative Agent may, at its option (but subject to the approval of
Determining Lenders), perform or attempt to perform such covenant, duty, or
agreement on behalf of the Company. In such event, any amount expended by
Administrative Agent in such performance or attempted performance shall be
payable by the Company, to Administrative Agent on demand, shall become part of
the Obligation, and shall bear interest at the Default Rate from the date of
such expenditure by Administrative Agent until paid. Notwithstanding the
foregoing, it is expressly


                                                             TERM LOAN AGREEMENT

                                       34
<PAGE>   39

understood that Administrative Agent does not assume and shall never have,
except by its express written consent, any liability or responsibility for the
performance of any covenant, duty, or agreement of the Company.

         10.4 Delegation of Duties and Rights. Lenders may perform any of their
duties or exercise any of their Rights under the Loan Papers by or through their
respective Representatives (provided, that such delegation does not release any
Lender of any of its obligations hereunder).

         10.5 Not in Control. Nothing in any Loan Paper shall, or shall be
deemed to (a) give any Agent or any Lender the Right to exercise control over
the assets (including real property), affairs, or management of the Company, (b)
preclude or interfere with compliance by the Company with any Law, or (c)
require any act or omission by the Company that may be harmful to Persons or
property. Any "material adverse event" or other materiality qualifier in any
representation, warranty, covenant, or other provision of any Loan Paper is
included for credit documentation purposes only and shall not, and shall not be
deemed to, mean that any Agent or any Lender acquiesces in any non-compliance by
the Company with any Law or document, or that any Agent or any Lender does not
expect the Company to promptly, diligently, and continuously carry out all
appropriate removal, remediation, and termination activities required or
appropriate in accordance with all Environmental Protection Statutes. No Agent
or Lender has any fiduciary relationship with or fiduciary duty to the Company
arising out of or in connection with the Loan Papers, and the relationship
between Agents and Lenders, on the one hand, and the Company, on the other hand,
in connection with the Loan Papers is solely that of debtor and creditor. The
power of Agents and Lenders under the Loan Papers is limited to the Rights
provided in the Loan Papers, which Rights exist solely to assure payment and
performance of the Obligation and may be exercised in a manner calculated by
Agents and Lenders in their respective good faith business judgment.

         10.6 Course of Dealing. The acceptance by Administrative Agent or
Lenders at any time and from time to time of partial payment on the Obligation
shall not be deemed to be a waiver of any Default then existing. No waiver by
Administrative Agent, Determining Lenders, or Lenders of any Default shall be
deemed to be a waiver of any other then-existing or subsequent Default. No delay
or omission by Administrative Agent, Determining Lenders, or Lenders in
exercising any Right under the Loan Papers shall impair such Right or be
construed as a waiver thereof or any acquiescence therein, nor shall any single
or partial exercise of any such Right preclude other or further exercise
thereof, or the exercise of any other Right under the Loan Papers or otherwise.

         10.7 Cumulative Rights. All Rights available to Administrative Agent
and Lenders under the Loan Papers are cumulative of and in addition to all other
Rights granted to Administrative Agent and Lenders at law or in equity, whether
or not the Obligation is due and payable and whether or not Administrative Agent
or Lenders have instituted any suit for collection, foreclosure, or other action
in connection with the Loan Papers.

         10.8 Application of Proceeds. Any and all proceeds ever received by
Administrative Agent or Lenders from the exercise of any Rights pertaining to
the Obligation shall be applied to the Obligation in the order and manner set
forth in Section 3.11.

         10.9 Limitation of Rights. Notwithstanding any other provision of this
Agreement or any other Loan Paper, any action taken or proposed to be taken by
Administrative Agent or any Lender under any Loan Paper which would affect the
operational, voting, or other control of the Company, shall be pursuant to any
applicable state Law, and the applicable rules and regulations thereunder.

         10.10 Expenditures by Lenders. The Company shall promptly pay within
thirty (30) days after request therefor (a) all reasonable costs, fees, and
expenses paid or incurred by any Agent incident to any


                                                             TERM LOAN AGREEMENT

                                       35

Loan Paper (including, but not limited to, the reasonable fees and expenses of
counsel to Administrative Agent and the allocated cost of internal counsel in
connection with the negotiation, preparation, delivery, execution, coordination,
and administration of the Loan Papers and any related amendment, waiver, or
consent) and (b) following the occurrence and continuation of a Default, all
reasonable costs and expenses of Lenders and Administrative Agent incurred by
Administrative Agent or any Lender in connection with the enforcement of the
obligations of the Company arising under the Loan Papers (including, without
limitation, costs and expenses incurred in connection with any workout or
bankruptcy) or the exercise of any Rights arising under the Loan Papers
(including, but not limited to, reasonable attorneys' fees including allocated
cost of internal counsel, court costs and other costs of collection), all of
which shall be a part of the Obligation and shall bear interest at the Default
Rate from the date due until the date repaid by the Company.

         10.11 INDEMNIFICATION. THE COMPANY AGREES TO INDEMNIFY AND HOLD
HARMLESS EACH AGENT, ARRANGER, AND EACH LENDER AND EACH OF THEIR RESPECTIVE
AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS, AND ADVISORS (EACH, AN "INDEMNIFIED PARTY") FROM AND AGAINST ANY AND
ALL CLAIMS, DAMAGES, ACTUAL LOSSES, LIABILITIES, COSTS, AND EXPENSES (INCLUDING,
WITHOUT LIMITATION, REASONABLE ATTORNEYS' FEES) (BUT SPECIFICALLY EXCLUDING
TAXES), THAT MAY BE INCURRED BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED
PARTY, IN EACH CASE ARISING OUT OF OR IN CONNECTION WITH OR BY REASON OF
(INCLUDING, WITHOUT LIMITATION, IN CONNECTION WITH ANY INVESTIGATION,
LITIGATION, OR PROCEEDING OR PREPARATION OF DEFENSE IN CONNECTION THEREWITH) THE
LOAN PAPERS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR
PROPOSED USE OF THE PROCEEDS OF THE BORROWINGS (INCLUDING ANY OF THE FOREGOING
ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY), EXCEPT TO THE EXTENT SUCH
CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE IS FOUND IN A FINAL,

SECTION 11 AGREEMENT AMONG LENDERS

         11.1 Administrative Agent.

                  (a) Each Lender hereby appoints Credit Lyonnais New York
         Branch (and Credit Lyonnais New York Branch hereby accepts such
         appointment) as its nominee and agent, in its name and on its behalf:
         (i) to act as nominee for and on behalf of such Lender in and under all
         Loan Papers; (ii) to arrange the means whereby the funds of Lenders are
         to be made available to the Company under the Loan Papers; (iii) to
         take such action as may be requested by any Lender under the Loan
         Papers (when such Lender is entitled to make such request under the
         Loan Papers and after such requesting Lender has obtained the
         concurrence of such other Lenders as may be required under the Loan
         Papers); (iv) to receive all documents and items to be furnished to
         Lenders under the Loan Papers; (v) to be the secured party, mortgagee,
         beneficiary, and similar party in respect of, and to receive, as the
         case may be, any collateral for the benefit of Lenders; (vi) to timely
         distribute, and Administrative Agent agrees to so distribute, to each
         Lender all material information, requests, documents, and items
         received from the Company under the Loan Papers (including written
         disclosures pursuant to Section 8.2 (other than pursuant to Section 8.2
         (d), which shall only be distributed to the requesting Lender), Section
         7.6 and Section 7.11); (vii) to promptly distribute to each Lender its
         ratable part of each payment or prepayment (whether voluntary, as
         proceeds of collateral upon or after foreclosure, as proceeds of
         insurance thereon, or otherwise) in accordance with the terms of the
         Loan Papers; (viii) to deliver to the appropriate Persons requests,
         demands, approvals, and consents received from Lenders; and (ix) to
         execute, on behalf of Lenders, such releases or other documents or
         instruments as are permitted by the Loan Papers or as directed by
         Lenders or Determining Lenders (when entitled to so authorize) from
         time to time; provided, however, Administrative Agent shall not be
         required to take any action which exposes Administrative Agent to
         personal liability or which is contrary to the Loan Papers or
         applicable Law.

                  (b) Administrative Agent may resign at any time as
         Administrative Agent under the Loan Papers by giving written notice
         thereof to Lenders. Should the initial or any successor Administrative
         Agent ever cease to be a party hereto or should the initial or any
         successor Administrative Agent ever resign as Administrative Agent,
         then Determining Lenders shall elect the successor Administrative Agent
         from among the Lenders (other than the resigning Administrative Agent).
         If no successor Administrative Agent shall have been so appointed by
         Determining Lenders, within 30 days after the retiring Administrative
         Agent's giving of notice of resignation, then the retiring
         Administrative Agent may, on behalf of Lenders, appoint a successor
         Administrative Agent, which shall be a commercial bank having a
         combined capital and surplus of at least $1,000,000,000. Upon the
         acceptance of any appointment as Administrative Agent under the Loan
         Papers by a successor Administrative Agent, such successor
         Administrative Agent shall thereupon succeed to and become vested with
         all the Rights of the retiring Administrative Agent, and the retiring
         Administrative Agent shall be discharged from its duties and
         obligations of Administrative Agent under the Loan Papers and each
         Lender shall execute such documents as any Lender may reasonably
         request to reflect such change in and under the Loan Papers. After any
         retiring Administrative Agent's resignation as Administrative Agent
         under the Loan Papers, the provisions of this Section 11 shall inure to
         its benefit as to any actions taken or omitted to be taken by it while
         it was Administrative Agent under the Loan Papers.

                  (c) Administrative Agent, in its capacity as a Lender, shall
         have the same Rights under the Loan Papers as any other Lender and may
         exercise the same as though it were not acting as Administrative Agent;
         the term "Lender" shall, unless the context otherwise indicates,
         include


                                                             TERM LOAN AGREEMENT

                                       37
<PAGE>   42

         Administrative Agent; and any resignation of Administrative Agent
         hereunder shall not impair or otherwise affect any Rights which it has
         or may have in its capacity as an individual Lender. Each Lender and
         the Company agree that Administrative Agent is not a fiduciary for
         Lenders or for the Company but simply is acting in the capacity
         described herein to alleviate administrative burdens for both the
         Company and Lenders, that Administrative Agent has no duties or
         responsibilities to Lenders or the Company except those expressly set
         forth herein, and that Administrative Agent in its capacity as a Lender
         has all Rights of any other Lender.

                  (d) Administrative Agent and its Affiliates may now or
         hereafter be engaged in one or more loan, letter of credit, leasing, or
         other financing transactions with the Company, act as trustee or
         depositary for the Company, or otherwise be engaged in other
         transactions with the Company (collectively, the "other activities")
         not the subject of the Loan Papers. Without limiting the Rights of
         Lenders specifically set forth in the Loan Papers, Administrative Agent
         and its Affiliates shall not be responsible to account to Lenders for
         such other activities, and no Lender shall have any interest in any
         other activities, any present or future guaranties by or for the
         account of the Company which are not contemplated or included in the
         Loan Papers, any present or future offset exercised by Administrative
         Agent and its Affiliates in respect of such other activities, any
         present or future property taken as security for any such other
         activities, or any property now or hereafter in the possession or
         control of Administrative Agent or its Affiliates which may be or
         become security for the obligations of the Company arising under the
         Loan Papers by reason of the general description of indebtedness
         secured or of property contained in any other agreements, documents or
         instruments related to any such other activities; provided that, if any
         payments in respect of such guaranties or such property or the proceeds
         thereof shall be applied to reduction of the obligations of the Company
         arising under the Loan Papers, then each Lender shall be entitled to
         share in such application ratably. Each Lender acknowledges that, and
         consents to, Credit Lyonnais New York Branch's also serving as
         Administrative Agent under that certain Letter of Credit and
         Reimbursement Agreement of even date herewith among the Company, Credit
         Lyonnais New York Branch, as "Administrative Agent," and certain
         financial institutions party thereto.

         11.2 Expenses. Upon demand by Administrative Agent, each Lender shall
pay its Pro Rata Part of any reasonable expenses (including, without limitation,
court costs, reasonable attorneys' fees and other costs of collection) incurred
by Administrative Agent in connection with any of the Loan Papers if and to the
extent Administrative Agent does not receive reimbursement therefor from other
sources within 60 days after incurred; provided that, each Lender shall be
entitled to receive its Pro Rata Part of any reimbursement for such expenses, or
part thereof, which Administrative Agent subsequently receives from such other
sources.

         11.3 Proportionate Absorption of Losses. Except as otherwise provided
in the Loan Papers, nothing in the Loan Papers shall be deemed to give any
Lender any advantage over any other Lender insofar as the Obligation arising
under the Loan Papers is concerned, or to relieve any Lender from absorbing its
Pro Rata Part of any losses sustained with respect to the Obligation (except to
the extent such losses result from unilateral actions or inactions of any Lender
that are not made in accordance with the terms and provisions of the Loan
Papers).

         11.4 Delegation of Duties; Reliance. Administrative Agent may perform
any of its duties or exercise any of its Rights under the Loan Papers by or
through its Representatives. Administrative Agent and its Representatives shall
(a) be entitled to rely upon (and shall be protected in relying upon) any
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telecopy, telegram, telex or teletype message, statement, order, or other
documents or conversation believed by it or them to be genuine and correct and
to have been signed or made by the proper Person and, with respect to legal


                                                             TERM LOAN AGREEMENT

                                       38

matters, upon opinion of counsel selected by Administrative Agent, (b) be
entitled to deem and treat each Lender as the owner and holder of the Principal
Debt owed to such Lender for all purposes until, subject to Section 12.13,
written notice of the assignment or transfer thereof shall have been given to
and received by Administrative Agent (and any request, authorization, consent,
or approval of any Lender shall be conclusive and binding on each subsequent
holder, assignee, or transferee of the Principal Debt owed to such Lender or
portion thereof until such notice is given and received), (c) not be deemed to
have notice of the occurrence of a Default unless a responsible officer of
Administrative Agent, who handles matters associated with the Loan Papers and
transactions thereunder, has actual knowledge thereof or Administrative Agent
has been notified thereof by a Lender or the Company, and (d) be entitled to
consult with legal counsel (including counsel for the Company), independent
accountants and other experts selected by Administrative Agent and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts.

         11.5 Limitation of Liability.

                  (a) None of the Agents or any of their respective
         Representatives shall be liable for any action taken or omitted to be
         taken by it or them under the Loan Papers in good faith and reasonably
         believed by it or them to be within the discretion or power conferred
         upon it or them by the Loan Papers or be responsible for the
         consequences of any error of judgment, except for fraud, gross
         negligence, or willful misconduct; and none of the Agents, or any of
         their respective Representatives has a fiduciary relationship with any
         Lender by virtue of the Loan Papers (provided that nothing herein shall
         negate the obligation of Administrative Agent to account for funds
         received by it for the account of any Lender).

                  (b) Unless indemnified to its satisfaction against loss, cost,
         liability, and expense, no Agent shall be compelled to do any act under
         the Loan Papers or to take any action toward the execution or
         enforcement of the powers thereby created or to prosecute or defend any
         suit in respect of the Loan Papers. If Administrative Agent requests
         instructions from Lenders or Determining Lenders, as the case may be,
         with respect to any act or action (including, but not limited to, any
         failure to act) in connection with any Loan Paper, such Agent shall be
         entitled (but shall not be required) to refrain (without incurring any
         liability to any Person by so refraining) from such act or action
         unless and until it has received such instructions. In no event,
         however, shall any Agent or any of its respective Representatives be
         required to take any action which it or they determine could incur for
         it or them criminal or onerous civil liability. Without limiting the
         generality of the foregoing, no Lender shall have any right of action
         against any Agent as a result of such Agent's acting or refraining from
         acting hereunder in accordance with the instructions of Determining
         Lenders.

                  (c) No Agent shall be responsible in any manner to any Lender
         or any Participant for, and each Lender represents and warrants that it
         has not relied upon any Agent in respect of, (i) the creditworthiness
         of the Company and the risks involved to such Lender, (ii) the
         effectiveness, enforceability, genuineness, validity, or the due
         execution of any Loan Paper, (iii) any representation, warranty,
         document, certificate, report, or statement made therein or furnished
         thereunder or in connection therewith, (iv) the existence, priority, or
         perfection of any Lien hereafter granted or purported to be granted
         under any Loan Paper, or (v) observation of or compliance with any of
         the terms, covenants, or conditions of any Loan Paper on the part of
         the Company. Each Lender agrees to indemnify Agents and their
         respective Representatives and hold them harmless from and against (but
         limited to such Lender's Pro Rata Part of) any and all liabilities,
         obligations, losses, damages, penalties, actions, judgments, suits,
         costs, reasonable expenses, and reasonable disbursements of any kind or
         nature whatsoever which may be imposed on, asserted against, or
         incurred by them in any way relating to or arising out of the Loan
         Papers


                                                             TERM LOAN AGREEMENT

                                       39
<PAGE>   44

         or any action taken or omitted by them under the Loan Papers, to the
         extent such Agents and their respective Representatives are not
         reimbursed for such amounts by the Company (provided that, no Agent or
         its Representatives shall have the right to be indemnified hereunder
         for its or their own fraud, gross negligence, or willful misconduct);
         and provided, further, that no Designated Lender shall be liable for
         any payment under this Section 11.5(c) so long as, and to the extent
         that, its Designating Lender makes such payments in accordance with,
         and at the time required by, the terms of this Agreement.

         11.6 Default; Collateral. Upon the occurrence and continuance of a
Default, Lenders agree to promptly confer in order that Determining Lenders or
Lenders, as the case may be, may agree upon a course of action for the
enforcement of the Rights of Lenders; and Administrative Agent shall be entitled
to refrain from taking any action (without incurring any liability to any Person
for so refraining) unless and until Administrative Agent shall have received
instructions from Determining Lenders. In actions with respect to any property
of the Company, Administrative Agent is acting for the ratable benefit of each
Lender. Any and all agreements to subordinate (whether made heretofore or
hereafter) other indebtedness or obligations of the Company to the Obligation
shall be construed as being for the ratable benefit of each Lender. If
Administrative Agent acquires any security for the Obligation or any guaranty of
the Obligation upon or in lieu of foreclosure, the same shall be held for the
Pro Rata benefit of all Lenders.

         11.7 Limitation of Liability. To the extent permitted by Law (a) no
Agent (acting in their respective agent capacities) shall incur any liability to
any other Lender or Participant except for acts or omissions resulting from its
own fraud, gross negligence or wilful misconduct, and (b) no Agent, Lender, or
Participant shall incur any liability to any other Person for any act or
omission of any other Lender, Agent, or Participant.

         11.8 Relationship of Lenders. Nothing herein shall be construed as
creating a partnership or joint venture among Agents and Lenders.

         11.9 Benefits of Agreement. Except for the representations and
covenants in Section 11.1(c) in favor of the Company, none of the provisions of
this Section 11 shall inure to the benefit of the Company or any other Person
other than Lenders; consequently, neither the Company nor any other Person shall
be entitled to rely upon, or to raise as a defense, in any manner whatsoever,
the failure of any Agent or Lender to comply with such provisions.

         11.10 Agents. None of the Lenders identified in this Agreement as
"Syndication Agent" or "Documentation Agent" shall have any rights, powers,
obligations, liabilities, responsibilities, or duties under this Agreement other
than those applicable to all Lenders as such. Without limiting the foregoing,
none of the Lenders so identified as a "Syndication Agent" or "Documentation
Agent" shall have or be deemed to have any fiduciary relationship with any
Lender.

         11.11 Obligation Several. The obligations of Lenders hereunder are
several, and each Lender hereunder shall not be responsible for the obligations
of the other Lenders hereunder, nor will the failure of one Lender to perform
any of its obligations hereunder relieve the other Lenders from the performance
of their respective obligations hereunder.

SECTION 12 MISCELLANEOUS

         12.1 Headings. The headings, captions, and arrangements used in any of
the Loan Papers are, unless specified otherwise, for convenience only and shall
not be deemed to limit, amplify, or modify the terms of the Loan Papers, nor
affect the meaning thereof.

<PAGE>   45

         12.2 Nonbusiness Days. In any case where any payment or action is due
under any Loan Paper on a day which is not a Business Day, such payment or
action may be delayed until the next-succeeding Business Day, but interest and
fees shall continue to accrue in respect of any payment to which it is
applicable until such payment is in fact made; provided that, if in the case of
any such payment in respect of a Eurodollar Rate Borrowing the next-succeeding
Business Day is in the next calendar month, then such payment shall be made on
the next-preceding Business Day.

         12.3 Communications. Unless specifically otherwise provided, whenever
any Loan Paper requires or permits any consent, approval, notice, request, or
demand from one party to another, such communication must be in writing (which
may be by telex or telecopy) to be effective and shall be deemed to have been
given (a) if by telex, when transmitted to the telex number, if any, for such
party, and the appropriate answer back is received, (b) if by telecopy, when
transmitted to the telecopy number for such party (and all such communications
sent by telecopy shall be confirmed promptly thereafter by personal delivery or
mailing in accordance with the provisions of this section; provided, that any
requirement in this parenthetical shall not affect the date on which such
telecopy shall be deemed to have been delivered), (c) if by mail, on the third
Business Day after it is enclosed in an envelope, properly addressed to such
party, properly stamped, sealed, and deposited in the appropriate official
postal service, or (d) if by any other means, when actually delivered to such
party. Until changed by notice pursuant hereto, the address (and telex and
telecopy numbers, if any) for Administrative Agent and each Lender is set forth
on Schedule 2.1, and for the Company is the address set forth by the Company's
signature on the signature page of this Agreement. A copy of each communication
to Administrative Agent shall also be sent to Haynes and Boone, LLP, 901 Main
Street, Dallas, Texas 75202, Fax: 214/651-5940, Attn: Timothy Powers.

         12.4 Form and Number of Documents. Each agreement, document,
instrument, or other writing to be furnished under any provision of this
Agreement must be in form and substance and in such number of counterparts as
may be reasonably satisfactory to Administrative Agent and its counsel.

         12.5 Exceptions to Covenants. The Company shall not take any action or
fail to take any action which is permitted as an exception to any of the
covenants contained in any Loan Paper if such action or omission would result in
the breach of any other covenant contained in any of the Loan Papers.

         12.6 Survival. All covenants, agreements, undertakings,
representations, and warranties made in any of the Loan Papers shall survive all
closings under the Loan Papers and, except as otherwise indicated, shall not be
affected by any investigation made by any party. All rights of, and provisions
relating to, reimbursement and indemnification of any Agent or any Lender shall
survive termination of this Agreement and payment in full of the Obligation.

         12.7 GOVERNING LAW. THE LAWS OF THE STATE OF NEW YORK AND OF THE
UNITED STATES OF AMERICA SHALL GOVERN THE RIGHTS AND DUTIES OF THE PARTIES TO
THE LOAN PAPERS AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION
OF THE LOAN PAPERS.

         12.8 Invalid Provisions. If any provision in any Loan Paper is held to
be illegal, invalid, or unenforceable, such provision shall be fully severable;
the appropriate Loan Paper shall be construed and enforced as if such provision
had never comprised a part thereof; and the remaining provisions thereof shall
remain in full force and effect and shall not be affected by such provision or
by its severance therefrom. Administrative Agent, Lenders, and the Company agree
to negotiate, in good faith, the terms of a replacement provision as similar to
the severed provision as may be possible and be legal, valid, and enforceable.

AGENTS SHALL BE DETERMINED SOLELY FROM WRITTEN AGREEMENTS, DOCUMENTS, AND
INSTRUMENTS, AND ANY PRIOR ORAL AGREEMENTS BETWEEN SUCH PARTIES ARE SUPERSEDED
BY AND MERGED INTO SUCH WRITINGS. THIS AGREEMENT (AS AMENDED IN WRITING FROM
TIME TO TIME) AND THE OTHER WRITTEN LOAN PAPERS EXECUTED BY THE COMPANY, ANY
LENDER, OR ANY AGENT (TOGETHER WITH ALL COMMITMENT LETTERS AND FEE LETTERS AS
THEY RELATE TO THE PAYMENT OF FEES AFTER THE CLOSING DATE) REPRESENT THE FINAL

foregoing waivers is intended to be all-encompassing of any and all disputes
that may be filed in any court and that relate to the subject matter of this

IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, SUPPLEMENTS, AND
REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN PAPER. In the event of Litigation,
this Agreement may be filed as a written consent to a trial by the court.

         12.11 Amendments, Consents, Conflicts, and Waivers.

                  (a) Except as otherwise specifically provided, (i) this
         Agreement may only be amended, modified or waived by an instrument in
         writing executed jointly by the Company and Determining Lenders, and,
         in the case of any matter affecting Administrative Agent, by
         Administrative Agent, and may only be supplemented by documents
         delivered or to be delivered in accordance with the express terms
         hereof, and (ii) the other Loan Papers may only be the subject of an
         amendment, modification, or waiver if the Company and Determining
         Lenders, and, in the case of any matter affecting Administrative Agent,
         Administrative Agent, have approved same.


                                                             TERM LOAN AGREEMENT

<PAGE>   47

                  (b) Any amendment to or consent or waiver under this Agreement
         or any Loan Paper which purports to accomplish any of the following
         must be by an instrument in writing executed by the Company and
         executed (or approved, as the case may be) by each Lender, and, in the
         case of any matter affecting Administrative Agent, by Administrative
         Agent: (i) extends the due date or decreases the amount of any
         scheduled payment of the Obligation arising under Loan Papers beyond
         the date specified in the Loan Papers; (ii) reduces the interest rate
         or decreases the amount of interest, fees, or other sums payable to
         Administrative Agent or Lenders hereunder (except such reductions as
         are contemplated by this Agreement); or (iii) reduces the percentage
         specified in the definition of "Determining Lenders"; (iv) changes this
         clause (b) or any other matter specifically requiring the consent of
         all Lenders hereunder; or (v) consents to the assignment or transfer of
         the Company of any of its rights and obligations under this Agreement.
         Without the consent of such Lender, no Lender's "Committed Sum" under
         the Term Facility may be increased. Without the consent of
         Administrative Agent and Determining Lenders, no provision of Section
         11 may be amended, modified, or waived. Each Designating Lender shall
         act on behalf of its Designated Lender with respect to any rights of
         its Designated Lender to grant or withhold any consent hereunder to the
         fullest extent it has been so delegated to act by its Designated Lender
         pursuant to its Designation Agreement.

                  (c) Any conflict or ambiguity between the terms and provisions
         herein and terms and provisions in any other Loan Paper shall be
         controlled by the terms and provisions herein.

                  (d) No course of dealing nor any failure or delay by
         Administrative Agent, any Lender, or any of their respective
         Representatives with respect to exercising any Right of Administrative
         Agent or any Lender hereunder shall operate as a waiver thereof. A
         waiver must be in writing and signed by Administrative Agent and
         Determining Lenders (or by all Lenders, if required hereunder) to be
         effective, and such waiver will be effective only in the specific
         instance and for the specific purpose for which it is given.

         12.12 Multiple Counterparts. This Agreement may be executed in a
number of identical counterparts, each of which shall be deemed an original for
all purposes and all of which constitute, collectively, one agreement; but, in
making proof of this Agreement, it shall not be necessary to produce or account
for more than one such counterpart. It is not necessary that each Lender execute
the same counterpart so long as identical counterparts are executed by the
Company, each Lender, and Administrative Agent. This Agreement shall become
effective when counterparts hereof shall have been executed and delivered to
Administrative Agent by each Lender, Administrative Agent, and the Company, or,
when Administrative Agent shall have received telecopied, telexed, or other
evidence satisfactory to it that such party has executed and is delivering to
Administrative Agent a counterpart hereof.

         12.13 Successors and Assigns; Assignments and Participations.

                  (a) This Agreement shall be binding upon, and inure to the
         benefit of the parties hereto and their respective successors and
         assigns, except that (i) the Company may not, directly or indirectly,
         assign or transfer, or attempt to assign or transfer, any of its
         Rights, duties or obligations under any Loan Papers without the express
         written consent of all Lenders, and (ii) except as permitted under this
         Section, no Lender may transfer, pledge, assign, sell any participation
         in, or otherwise encumber its portion of the Obligation.


                                                             TERM LOAN AGREEMENT

<PAGE>   48

                  (b) Each Lender may assign to one or more Eligible Assignees
         all or a portion of its Rights and obligations under this Agreement and
         the other Loan Papers (including, without limitation, all or a portion
         of its Borrowings and its Note); provided, however, that:

                           (i) each such assignment shall be to an Eligible
                  Assignee;

                           (ii) except in the case of an assignment to another
                  Lender or an assignment of all of a Lender's Rights and
                  obligations under this Agreement and the other Loan Papers,
                  any such partial assignment shall be in an amount at least
                  equal to $10,000,000 (or such lower amount as may be requested
                  by a Lender and agreed to by Administrative Agent, acting in
                  its sole discretion);

                           (iii) each such assignment by a Lender shall be of a
                  constant, and not varying, percentage of all of its Rights and
                  obligations under this Agreement and the Notes; and

                           (iv) the parties to such assignment shall execute and
                  deliver to the Administrative Agent for its acceptance an
                  Assignment and Acceptance Agreement in the form of Exhibit C
                  hereto, together with any Notes subject to such assignment and
                  a processing fee of $3,000.

         Upon execution, delivery, and acceptance of such Assignment and
         Acceptance Agreement, the assignee thereunder shall be a party hereto
         and, to the extent of such assignment, have the obligations, Rights,
         and benefits of a Lender under the Loan Papers and the assigning Lender
         shall, to the extent of such assignment, relinquish its rights and be
         released from its obligations under the Loan Papers. Upon the
         consummation of any assignment pursuant to this Section, the Company
         shall issue appropriate Notes to the assignor and the assignee,
         reflecting such Assignment and Acceptance. If the assignee is not
         incorporated under the laws of the United States of America or a state
         thereof, it shall deliver to the Company and Administrative Agent
         certification as to exemption from deduction or withholding of Taxes in
         accordance with Section 4.6.

                  (c) Administrative Agent shall maintain at its address
         referred to in Section 12.3 a copy of each Assignment and Acceptance
         Agreement delivered to and accepted by it and a register for the
         recondition of the names and addresses of the Lenders and their
         respective Committed Sums, and principal amount of the Borrowings owing
         to each Lender from time to time (the "Register"). The entries in the
         Register shall be conclusive and binding for all purposes, absent
         manifest error, and the Company, Administrative Agent and Lenders may
         treat each Person whose name is recorded in the Register as a Lender
         hereunder for all purposes of the Loan Papers. The Register shall be
         available for inspection by the Company or any Lender at any reasonable
         time and from time to time upon reasonable prior notice. Upon the
         consummation of any assignment in accordance with this Section 12.13,
         Schedule 2.1 shall automatically be deemed amended (to the extent
         required) by Administrative Agent to reflect the name, address, and
         respective Committed Sums of the assignor and assignee.

                  (d) Upon its receipt of an Assignment and Acceptance Agreement
         executed by the parties thereto, together with any Notes subject to
         such assignment and payment of the processing fee, Administrative Agent
         shall, if such Assignment and Acceptance has been completed and is in
         substantially the form of Exhibit C hereto, (i) accept such Assignment
         and Acceptance Agreement, (ii) record the information contained therein
         in the Register and (iii) give prompt notice thereof to the parties
         thereto.


                                                             TERM LOAN AGREEMENT

<PAGE>   49

                  (e) Subject to the provisions of this Section and in
         accordance with applicable Law, any Lender may, in the ordinary course
         of its commercial lending business and in accordance with applicable
         Law, at any time sell to one or more Persons (each a "Participant")
         participating interests in its portion of the Obligation. In the event
         of any such sale to a Participant, (i) such Lender shall remain a
         "Lender" under this Agreement and the Participant shall not constitute
         a "Lender" hereunder, (ii) such Lender's obligations under this
         Agreement shall remain unchanged, (iii) such Lender shall remain solely
         responsible for the performance thereof, (iv) such Lender shall remain
         the holder of its share of the Principal Debt for all purposes under
         this Agreement, (v) the Company and Administrative Agent shall continue
         to deal solely and directly with such Lender in connection with such
         Lender's Rights and obligations under the Loan Papers, and (vi) such
         Lender shall be solely responsible for any withholding taxes or any
         filing or reporting requirements relating to such participation and
         shall hold the Company and Administrative Agent and their respective
         successors, permitted assigns, officers, directors, employees, agents,
         and representatives harmless against the same. Participants shall have
         no Rights under the Loan Papers, other than certain voting Rights as
         provided below. Subject to the following, each Lender shall be entitled
         to obtain (on behalf of its Participants) the benefits of Section 4
         with respect to all participations in its part of the Obligation
         outstanding from time to time so long as the Company shall not be
         obligated to pay any amount in excess of the amount that would be due
         to such Lender under Section 4 calculated as though no participations
         have been made. No Lender shall sell any participating interest under
         which the Participant shall have any Rights to approve any amendment,
         modification, or waiver of any Loan Paper, except to the extent such
         amendment, modification, or waiver extends the due date for payment of
         any amount in respect of principal (other than mandatory prepayments),
         interest, or fees due under the Loan Papers, reduces the interest rate
         or the amount of principal or fees applicable to the Obligation (except
         such reductions as are provided by this Agreement), or releases any
         guaranty or collateral, if any, for the Obligation (except such
         releases as are contemplated by this Agreement); provided that, in
         those cases where a Participant is entitled to the benefits of Section
         4 or a Lender grants Rights to its Participants to approve amendments
         to or waivers of the Loan Papers respecting the matters previously
         described in this sentence, such Lender must include a voting mechanism
         in the relevant participation agreement or agreements, as the case may
         be, whereby a majority of such Lender's portion of the Obligation
         (whether held by such Lender or Participant) shall control the vote for
         all of such Lender's portion of the Obligation. Except in the case of
         the sale of a participating interest to another Lender, the relevant
         participation agreement shall not permit the Participant to transfer,
         pledge, assign, sell participations in, or otherwise encumber its
         portion of the Obligation, unless the consent of the transferring
         Lender (which consent will not be unreasonably withheld) has been
         obtained.

                  (f) Any Lender may at any time designate not more than one
         Designated Lender to fund Borrowings on behalf of such Designating
         Lender subject to the terms of this Section 12.13(f), and the
         provisions of Sections 12.13(b) and 12.13(e) shall not apply to such
         designation. No Lender may have more than one Designated Lender at any
         time. Such designation may occur either by the execution of the
         signature pages hereof by such Lender and Designated Lender next to the
         appropriate "Designating Lender" and "Designated Lender" captions, or
         by execution by such parties of a Designation Agreement subsequent to
         the date hereof; provided, that any Lender and its Designated Lender
         executing the signatures pages hereof as "Designating Lender" and
         "Designated Lender", respectively, on the date hereof shall be deemed
         to have executed a Designation Agreement, and shall be bound by the
         respective representations, warranties and covenants contained therein,
         and such designation shall be conclusively deemed to be accepted by the
         Company and the Administrative Agent. The parties to each such
         designation occurring subsequent to the execution date hereof shall
         execute and deliver to the Administrative Agent and the Company for
         their acceptance a Designation Agreement. Upon such receipt of an


                                                             TERM LOAN AGREEMENT

                                       45

         appropriately completed Designation Agreement executed by a Designating
         Lender and a designee representing that it is a Designated Lender and
         consented to by the Company and the Administrative Agent, the
         Administrative Agent will accept such Designation Agreement and will
         give prompt notice thereof to the Company and the other Lenders,
         whereupon, (i) the Company shall execute and deliver to the Designating
         Lender a Designated Lender Note payable to the order of the Designated
         Lender, (ii) from and after the effective date specified in the
         Designation Agreement, the Designated Lender shall become a party to
         this Agreement with a right to fund Borrowings on behalf of its
         Designating Lender pursuant to Section 2.1(b), and (iii) the Designated
         Lender shall not be required to make payments with respect to any
         obligations in this Agreement except to the extent of excess cash flow
         of such Designated Lender which is not otherwise required to repay
         obligations of such Designated Lender which are then due and payable;
         provided, however, that regardless of such designation and assumption
         by the Designated Lender, the Designating Lender shall be and remain
         obligated to the Company, the Administrative Agent and the Lenders for
         each and every of the obligations of the Designating Lender and its
         related Designated Lender with respect to this Agreement, including,
         without limitation, any indemnification obligations under Section
         11.5(c) hereof and any sums otherwise payable to the Company by the
         Designated Lender.

                  Each Designating Lender, or a specified branch or affiliate
         thereof, shall serve as the administrative agent of its Designated
         Lender and shall on behalf of its Designated Lender: (i) receive any
         and all payments made for the benefit of such Designated Lender and
         (ii) give and receive all communications and notices and take all
         actions hereunder, including, without limitation, votes, approvals,
         waivers, consents and amendments under or relating to this Agreement
         and the other Loan Papers. Any such notice, communication, vote,
         approval, waiver, consent or amendment shall be signed by a Designating
         Lender, or specified branch or affiliate thereof, as administrative
         agent for its Designated Lender and need not be signed by such
         Designated Lender on its own behalf. The Company, the Administrative
         Agent and the Lenders may rely thereon without any requirement that the
         Designated Lender sign or acknowledge the same. No Designated Lender
         may assign or transfer all or any portion of its interest hereunder or
         under any other Loan Paper, other than pursuant to an assignment to its
         Designating Lender pursuant to a pledge to its Liquidity Lender (if
         any) in accordance with Section 12.13(g) of this Agreement, or
         otherwise in accordance with the provisions of this Section 12.13.

                  (g) Notwithstanding any other provision set forth in this
         Agreement, (i) any Lender may at any time assign and pledge all or any
         portion of its Borrowings and its Note to any Federal Reserve Bank as
         collateral security pursuant to Regulation A and any Operating Circular
         issued by such Federal Reserve Bank. No such assignment shall release
         the assigning Lender from its obligations hereunder and (ii) any
         Designated Lender may at any time create a security interest in, or
         pledge, all or any portion of its rights under and interest in this
         Agreement and the Designated Lender Note held by it in favor of its
         Liquidity Bank, and such Liquidity Bank may enforce such pledge or
         security interest in any manner permitted under applicable law,
         provided that (y) such Liquidity Bank possesses the characteristics
         necessary to be an Eligible Assignee under this Agreement, and (z) no
         such pledge shall release the Designating Lender from its obligations
         hereunder or grant to such Liquidity Bank the rights of a Lender
         hereunder absent foreclosure of such pledge.

                  (h) Any Lender may furnish any information concerning the
         Company in the possession of such Lender from time to time to Eligible
         Assignees and Participants (including prospective Eligible Assignees
         and Participants), subject, however, to Section 12.15 hereof.

<PAGE>   51

         12.14 Discharge Only Upon Payment in Full; Reinstatement in Certain
Circumstances. The Company's obligations under the Loan Papers shall remain in
full force and effect until termination of the Commitment and payment in full of
the Principal Debt and of all interest, fees, and other amounts of the
Obligation then due and owing, except that Section 4, Section 10, and Section
12, and any other provisions under the Loan Papers expressly intended to survive
by the terms hereof or by the terms of the applicable Loan Papers, shall survive
such termination. If at any time any payment of the principal of or interest on
any Note or any other amount payable by the Company under any Loan Paper is
rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy, or reorganization of the Company or otherwise, the obligations of
the Company under the Loan Papers with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

         12.15 Confidentiality. Administrative Agent and each Lender (each, a
"Lending Party") agrees to use its best efforts to keep confidential any
information furnished or made available to it by the Company pursuant to this
Agreement that is marked confidential; provided that nothing herein shall
prevent any Lending Party from disclosing such information (a) to any other
Lending Party or any officer, director, employee, agent, or advisor of any
Lending Party, (b) to its auditors, accountants, legal counsel or other
professional advisors, (c) as required by any law, rule, or regulation, (d) upon
the order of any court or administrative agency, (e) upon the request or demand
of any regulatory agency or authority, (f) that is or becomes available to the
public or that is or becomes available to any Lending Party other than as a
result of a disclosure by any Lending Party prohibited by this Agreement, (g) in
connection with any litigation to which such Lending Party or any of its
affiliates may be a party, (h) to the extent necessary in connection with the
exercise of any remedy under this Agreement or any other Loan Paper, and (i)
subject to provisions substantially similar to those contained in this Section,
to any Affiliate of any Lending Party or to any actual or proposed participant
or assignee. The Company hereby consents to the disclosure of any non-public
information with respect to it which is related to this transaction by any
Designated Lender to any rating agency, commercial paper dealer, or provider of
a surety, guaranty or credit or liquidity enhancement to such Designated Lender.

         12.16 No Bankruptcy Proceedings. Each of the Company, the Lenders and
the Administrative Agent agrees that it will not institute against any
Designated Lender or join any other Person in instituting against any Designated
Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding under any federal or state bankruptcy or similar law, for one year
and one day after the payment in full of the latest maturing commercial paper
note issued by such Designated Lender; provided that the Designating Lender
hereby agrees to indemnify, save and hold harmless the Company, each Lender and
the Administrative Agent for any loss, cost, damage and expense arising out of
their inability to institute any such proceeding against its Designated Lender.

         EXECUTED on the respective dates shown on the signature pages hereto,
but effective as of the Closing Date.

                   FORM OF ASSIGNMENT AND ACCEPTANCE AGREEMENT


         Reference is made to the Term Loan Agreement dated as of April 7, 2000
(as amended, modified, supplemented, or restated from time to time, the
"Agreement") among THE WILLIAMS COMPANIES, INC., a Delaware corporation (the
"Company"), the Lenders, (each such term as defined in the Agreement), and
CREDIT LYONNAIS NEW YORK BRANCH, as the Administrative Agent for Lenders
("Administrative Agent"). Capitalized terms used herein and not otherwise
defined herein shall have the meanings assigned to such terms in the Agreement.

         The "Assignor" and the "Assignee" referred to on Schedule 1 agree as
follows:

         1. The Assignor hereby sells and assigns to the Assignee, without
recourse and without representation or warranty except as expressly set forth
herein, and the Assignee hereby purchases and assumes from the Assignor, an
interest in and to the Assignor's Rights and obligations under the Agreement and
the related Loan Papers as of the date hereof equal to the percentage interest
specified on Schedule 1. After giving effect to such sale and assignment, the
Assignor's and the Assignee's Committed Sums and the amount of the Borrowings
under the Term Facility owing to each of them will be as set forth on Schedule
1.

         2. The Assignor (i) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim; (ii) makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with the Loan Papers or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of the Loan Papers or any other instrument or document furnished pursuant
thereto; (iii) makes no representation or warranty and assumes no responsibility
with respect to the financial condition of any party to any Loan Paper or the
performance or observance by any such party of any of its obligations under the
Loan Papers or any other instrument or document furnished pursuant thereto; and
(iv) attaches the Note held by the Assignor and requests that Administrative
Agent exchange such Note for new Notes. Such new Notes shall be prepared in
accordance with the provisions of Section 3.1(a) of the Agreement and will
reflect the respective Committed Sums of the Assignee and the Assignor after
giving effect to this Assignment and Acceptance.

         3. The Assignee (i) confirms that it has received a copy of the
Agreement, together with copies of the current financials statements of the
Company furnished pursuant to the Agreement and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Assignment and Acceptance; (ii) agrees that it will,
independently and without reliance upon the Administrative Agent, the Assignor,
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under the Agreement; (iii) confirms that it is an
Eligible Assignee; (iv) appoints and authorizes Administrative Agent to take
such action as Administrative Agent on its behalf and to exercise such powers
and discretion under the Agreement as are delegated to Administrative Agent by
the terms thereof, together with such powers and discretion as are reasonably
incidental thereto; (v) agrees that it will perform in accordance with their
terms all of the obligations that by the terms of the Agreement are required to
be performed by it as a Lender.

         4. Following the execution of this Assignment and Acceptance, it will
be delivered to Administrative Agent for acceptance and recording by the
Administrative Agent. The effective date for



                                                                       EXHIBIT C
<PAGE>   80

this Assignment and Acceptance (the "Effective Date") shall be the date of
acceptance hereof by Administrative Agent, unless otherwise specified on
Schedule 1.

         5. Upon such acceptance and recording by Administrative Agent, as of
the Effective Date, (i) the Assignee shall be a party to the Agreement and, to
the extent provided in this Assignment and Acceptance, have the Rights and
obligations of a Lender thereunder, and (ii) the Assignor shall, to the extent
provided in this Assignment and Acceptance, relinquish its Rights and be
released from its obligations under the Agreement.

         6. Upon such acceptance and recording by Administrative Agent, from and
after the Effective Date, Administrative Agent shall make all payments under the
Agreement, the Notes, and loan accounts in respect of the interest assigned
hereby (including, without limitation, all payments of principal, interest, and
commitment fees and other fees with respect thereto) to the Assignee. The
Assignor and Assignee shall make all appropriate adjustments in payments under
the Agreement and the other Loan Papers for periods prior to the Effective Date
directly between themselves.

         7. Unless the Assignee is a Lender or an Affiliate of a Lender (and
this sale and assignment is not made in connection with the sale of such
Affiliate), this Assignment and Acceptance may be conditioned upon the consent
of the Company and Administrative Agent pursuant to the definition of "Eligible
Assignee" in the Agreement. The execution and delivery of this Assignment and
Acceptance by the Company and Administrative Agent is evidence of this consent.

         8. As contemplated by Section 12.13(b)(vi) of the Agreement, the
Assignor or the Assignee (as determined between the Assignor and the Assignee)
agrees to pay to Administrative Agent for its account on the Effective Date in
federal funds a processing fee of $3,000.

         9. THIS ASSIGNMENT AND ACCEPTANCE SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE UNITED STATES OF
AMERICA AND THE STATE OF NEW YORK.

         10. This Assignment and Acceptance may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of Schedule 1 to this Assignment and Acceptance by Telecopied shall
be effective as delivery of a manually executed counterpart of this Assignment
and Acceptance.

         IN WITNESS WHEREOF, the Assignor and the Assignee have caused Schedule
1 to this Assignment and Acceptance to be executed by their officers hereunto
duly authorized as of the date specified thereon.

                FORM OF OPINION OF GENERAL COUNSEL OF THE COMPANY




Credit Lyonnais New York Branch, in its capacities as
   Administrative Agent
Commerzbank AG New York and Grand Cayman Branches, as Syndication Agent
The Bank of Nova Scotia, as Documentation Agent

Each of the Lenders named in Schedules 2.1 to the Agreement referred to below

         Re:   Term Loan Facility of The Williams Companies, Inc.

Ladies and Gentlemen:

         This opinion is furnished to you pursuant to Section 6.1 of the Term
Loan Agreement dated as of April 7, 2000 (the "Agreement"), by and among The
Williams Companies, Inc. (the "Company"), the Lenders described therein, The
Bank of Nova Scotia, as Documentation Agent, Commerzbank AG New York and Grand
Cayman Branches, as Syndication Agent, and Credit Lyonnais New York Branch, as
Administrative Agent for the Lenders (the "Administrative Agent"). Terms defined
in the Agreement are used herein as therein defined.

         I am the General Counsel of the Company, and I and other attorneys
acting under my supervision have acted as counsel for the Company in connection
with the preparation, execution, and delivery of the Agreement.

         In that connection, I or attorneys acting under my supervision have
examined:

         (1) Original counterparts of the Agreement executed by the Company, the
Lenders, and the Agents;

         (2) The documents furnished by the Company pursuant to Section 6.1 of
the Agreement;

         (3) The Certificate of Incorporation of the Company and all amendments
thereto (the "Charter");

         (4) The Bylaws of the Company and all amendments thereto (the
"Bylaws"); and

         (5) The Certificate of the Secretary of State of the State of Delaware
dated March 31, 2000, attesting to the continued corporate existence and good
standing of the Company in that State.

         I, or attorneys acting under my supervision, have also examined the
originals, or copies certified to our satisfaction, of such corporate records of
the Company, certificates of public officials and of officers of the Company and
agreements, instruments, and other documents, as I have deemed necessary as a
basis for the opinions expressed below. As to questions of fact material to such
opinions, I have, when relevant facts were not independently established by me
or attorneys acting under my supervision, relied upon certificates of officers
of the Company or of public officials. I have assumed (i) the genuineness of the
signatures of the Agents and the Lenders, (ii) the capacity of the signing
officers of the



                                                                       EXHIBIT D

Agents and the Lenders, (iii) the authenticity of all documents submitted to me
as originals and the conformity with the authentic originals of all documents
submitted to me as copies, and (iv) the due execution and delivery, pursuant to
due authorization, of the Agreement by the Agents and the Lenders and the
enforceability (subject to limitations on enforceability of the types referred
to in paragraphs (a) through (c) of this opinion) of the Agreement against the
Agents and the Lenders.

         Based upon the foregoing and upon such investigation as I have deemed
necessary, I am of the following opinion:

                  1. The Company (a) is a corporation duly organized, validly
         existing, and in good standing under the Laws of the State of Delaware,
         and (b) possesses all requisite corporate authority and power to
         conduct its business and execute, deliver, and comply with the terms of
         the Loan Papers, which have been duly authorized and approved by all
         necessary corporate action and for which, to the best of my knowledge,
         no approval or consent of any Person or Governmental Authority is
         required which has not been obtained.

                  2. Each of the Loan Papers has been duly executed and
         delivered by the Company.

                  3. The Loan Papers evidence the valid and legally binding
         obligations of the Company, enforceable against the Company in
         accordance with their respective terms.

                  4. The execution, delivery, and performance by the Company of
         the Loan Papers, and the Borrowings and use of the proceeds of the
         Borrowings thereunder as provided therein, (i) will not violate (A) the
         Charter or Bylaws of the Company; (B) any provision of law applicable
         to the Company (including, without limitation, Regulation X of the
         Board of Governors of the Federal Reserve System); or (C) any
         contractual or legal restriction of the Company of which I am aware,
         after reasonable inquiry, and (ii) will not result in, or require, the
         creation or imposition of any Lien prohibited by the Agreement.

                  5. To my knowledge, there is no reason the Company cannot make
         the representations set forth in Section 7.6 of the Agreement.

                  6. The execution, delivery, and performance by the Company of
         each of the Loan Papers to which it is a party will not violate any
         applicable Law of the State of New York, except for any such violations
         which could not reasonably be expected to have, either individually or
         in the aggregate, a material and adverse effect on the operations,
         financial condition or business of the Company and its Subsidiaries,
         taken as a whole.

         The opinions set forth above are subject to the following
qualifications:

                  (a) My opinion in paragraph 3 above is subject, insofar as
         enforceability is concerned, to the effect of bankruptcy, insolvency,
         reorganization, fraudulent conveyance, moratorium or similar law
         affecting creditors' rights and remedies generally.

                  (b) My opinion in paragraph 3 above is subject, insofar as
         enforceability is concerned, to the effect of general principles of
         equity, including principles of commercial reasonableness, good faith,
         and fair dealing (regardless of whether considered in a proceeding in
         equity or at law).

                  (c) I express no opinion with respect to the enforceability of
         any of the following: indemnification provisions to the extent same are
         violative of federal or state securities laws,



                                                                       EXHIBIT D

         rules, or regulations or of public policy, clauses waiving right to
         trial by jury, exculpation clauses, clauses granting offset rights to
         the Agents or any Lender or against any deposits or in respect of
         matured claims, clauses relating to recovery of attorneys' fees in
         connection with the enforcement of obligations, clauses relating to
         releases of unmatured claims, integration clauses to the effect that no
         representation was made other than as appears in the Agreement, clauses
         purporting to waive unmatured rights, representations, warranties, or
         affirmative or negative covenants to the extent such representations,
         warranties, or affirmative or negative covenants can be construed to be
         independent clauses which purport to be legal, valid, binding, and
         enforceable by themselves, as distinguished from being clauses which
         trigger an event of default, and severability and similar clauses, and
         clauses which incorporate by reference a document, instrument, or
         agreement not in existence on the date hereof to the extent that any
         such document, instrument, or agreement is the basis of an effort to
         enforce the Agreement, insofar as any of the foregoing are contained in
         the Agreement.

                  (d) I express no opinion as to the effect on the opinions
         herein stated of compliance or non-compliance by the Agents or any
         Lender with any applicable state, federal, or other laws or regulations
         applying only to banks, or the legal or regulatory status of any Agent
         or any Lender.

                  (e) I am admitted to practice law in the States of New York
         and Oklahoma and, accordingly, the opinions expressed herein are based
         upon and limited exclusively to the laws of the States of New York and
         Oklahoma, the General Corporation Law of the State of Delaware, and the
         laws of the United States of America insofar as any of such laws are
         applicable, and I render no opinion with respect to any other laws.

                  (f) My opinion in paragraph 1 above as to the good standing of
         the Company is based solely on the certificate, dated as of March 31,
         2000, from the Secretary of State of the State of Delaware certifying
         as to such matters.

         This opinion is addressed to you solely for your use in connection with
the transactions contemplated by the Loan Papers, and no person other than the
Agents, each Lender, each assignee which hereafter becomes a Lender as permitted
by the Agreement and the law firm of Haynes and Boone, LLP is entitled to rely
hereon without my prior written consent. This opinion is given as of the date
hereof, and I have no obligation to revise or update this opinion subsequent to
the date hereof or to advise you or any other person of any matter subsequent to
the date hereof which would cause me to modify this opinion in whole or in part.

                                             Very truly yours,

                          FORM OF DESIGNATION AGREEMENT

                          Dated _________________, 2000

         Reference is made to that certain Term Loan Agreement dated as of April
7, 2000 (as amended, supplemented or otherwise modified from time to time, the

         1. Pursuant to Section 2.1(b) of the Agreement, the Designating Lender
hereby designates the Designee, and the Designee hereby accepts such
designation, to have a right to fund Borrowings pursuant to Section 2.1(a) of
the Agreement. Any delegation by Designating Lender to Designee of its rights to
fund Borrowings pursuant to such Section 2.1(b) shall be effective at the time
of the funding of such Borrowing and not before such time.

         2. Except as set forth in Section 7 below, the Designating Lender makes
no representation or warranty and assumes no responsibility pursuant to this
Designation Agreement with respect to (a) any statements, warranties or
representations made in or in connection with any Loan Paper or the execution,

Loan Paper or any other instrument and document furnished pursuant thereto and
(b) the financial condition of the Company or the performance or observance by
the Company of any of its obligations under any Loan Paper or any other
instrument or document furnished pursuant thereto.

         3. The Designee (a) confirms that it has received a copy of each Loan

7.5 and 8.2 of the Agreement and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
this Designation Agreement; (b) agrees that it will independently and without
reliance upon the Administrative Agent, the Designating Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under any Loan Paper; (c) confirms that it is a Designated Lender; (d)
appoints and authorizes the Administrative Agent to take such action as
Administrative Agent on its behalf and to exercise such powers and discretion
under any Loan Paper as are delegated to the Administrative Agent by the terms
thereof, together with such powers and discretion as are reasonably incidental
thereto; and (e) agrees that it will perform in accordance with their terms all
of the obligations which by the terms of any Loan Paper are required to be
performed by it as a Lender.

         4. The Designee hereby appoints [Designating Lender or a specified
branch or affiliate of Designating Lender] as Designee's Administrative Agent
and attorney in fact and grants to [Designating Lender or a specified branch or
affiliate of Designating Lender] an irrevocable power of attorney to receive
payments made for the benefit of Designee under the Agreement, to deliver and
receive all communications and notices under the Agreement and other Loan Papers

approvals, waivers, consents of amendments to or under the Agreement or other
Loan Papers. Any document executed by such Administrative Agent on the
Designee's behalf in connection with the Agreement or other Loan Papers shall be
binding on the


                                                                       EXHIBIT E

                                       1

Designee. The Company, the Administrative Agent and each of the Lenders may rely
on and are beneficiaries of the preceding provisions.

         5. Following the execution of this Designation Agreement by the
Designating Lender, its Designee and the Company, it will be delivered to the
Administrative Agent for acceptance and recording by the Administrative Agent.
The effective date for this Designation Agreement (the "Effective Date") shall
be the date of acceptance hereof by the Administrative Agent, unless otherwise
specified on the signature page thereto.

         6. Each of the Company, the Designating Lender and the Administrative
Agent hereby (i) acknowledges that the Designee is relying on the non-petition
provisions of Section 12.16 of the Agreement as agreed to by all signatories
thereto and (ii) reaffirms that it will not institute against the Designee or
join any other Person in instituting against the Designee any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under any
federal or state bankruptcy or similar law for one year and one day after the
payment in full of the latest maturing commercial paper note issued by the
Designee.

         7. The Designating Lender unconditionally agrees to pay or reimburse
the Designee and save the Designee harmless against all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
or asserted by any of the parties to the Loan Papers against the Designee, in
its capacity as such, in any way relating to or arising out of this Agreement or
any other Loan Papers or any action taken or omitted by the Designee hereunder
or thereunder, provided that the Designating Lender shall not be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements if the same results from the
Designee's gross negligence or willful misconduct.

         8. Upon such acceptance and recording by the Administrative Agent, as
of the Effective Date, the Designee shall be a party to the Agreement with a
right to fund Borrowings as a Designated Lender pursuant to Section 2.1(b) of
the Agreement and the rights and obligations of a Designated Lender related
thereto; provided, however, that the Designee shall not be required to make
payments with respect to such obligations except to the extent of excess cash
flow of the Designee which is not otherwise required to repay obligations of the
Designee Lender which are then due and payable. Notwithstanding the foregoing,
the [Designating Lender or a specified branch or affiliate of Designating
Lender], as administrative agent for the Designee, shall be and remain obligated
to the Company, the Administrative Agent and the Lenders for each and every of
the obligations of the Designee and the Designating Lender with respect to the
Agreement, including, without limitation, any indemnification obligations under
Section 11.5(c) of the Agreement and any sums otherwise payable to the Company
by the Designee.

         9. This Designation Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

         10. This Designation Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of a signature page to this Designation Agreement by facsimile
transmission shall be effective as delivery of a manually executed counterpart
of this Designation Agreement.



                                                                       EXHIBIT E
