conditions set forth herein, upon request of the Company to make loans to the
Company (each such loan, a "Revolving Loan") from time to time on any Business

aggregate outstanding amount not to exceed at any time such Bank's Pro Rata

Bank's Pro Rata Share of the Commitment, and subject to the other terms and
conditions hereof, the Company may borrow under this subsection 2.1(a), prepay

respect thereto.  Each Bank is irrevocably authorized by the Company to endorse

     Eurodollar Loans, such Interest Period shall be one month.

     Loans having Interest Periods expiring on such day (or any part thereof in
     an amount not less than $5,000,000, or that is in an integral multiple of
     $1,000,000 in excess thereof);

provided, that if at any time the aggregate amount of Eurodollar Loans in
respect of any Borrowing is reduced, by payment, prepayment, or conversion of

Company to continue such Loans as, and convert such Loans into, Eurodollar
Loans, as the case may be, shall terminate.

Company shall be deemed to have elected to convert such Loans into Base Rate
Loans effective as of the expiration date of such Interest Period.

     (d)  The Administrative Agent will promptly notify each Bank of its receipt
of a Notice of Conversion/Continuation, or, if no timely notice is provided by
the Company, the Administrative Agent will promptly notify each Bank of the
details of any automatic conversion.  All conversions and continuations shall be
made ratably according to the respective outstanding principal amounts of the
Loans held by each Bank with respect to which the notice was given.

the Commitment shall be applied to each Bank according to its Pro Rata Share.
All Non-Use Fees and Utilization Fees accrued until the effective date of any

becomes due until the date such amount is paid in full, and after as well as
before any entry of judgment thereon to the extent permitted by law, payable on

      (d) Anything herein to the contrary notwithstanding, the obligations of
the Company to any Bank hereunder shall be subject to the limitation that
payments of interest shall not be required for any period for which interest is
computed hereunder, to the extent (but only to the extent) that contracting for
or receiving such payment by such Bank would be contrary to the provisions of
any law applicable to such Bank limiting the highest rate of interest that may
be lawfully contracted for, charged or received by such Bank, and in such event
the Company shall pay such Bank interest at the highest rate permitted by
applicable law.

<PAGE>

          (i)  a fee (the "Utilization Fee") at the per annum rate set forth on
                           ---------------
     Schedule 1.1(A) corresponding to the higher of the Company's Debt Ratings
     on the total amount of Loans outstanding for each calendar quarter during
     the period from the Closing Date to the Termination Date in which the sum
     of (x) the average outstanding aggregate principal balance of the Loans,
     and (y) the average outstanding principal balance of the Five-Year Loans
     exceeds 33 1/3% of the sum of the Commitment and the Five-Year Commitment
     in effect for such calendar quarter; and

          (ii) a  fee (the "Non-Use Fee") for the period from the Closing Date
                            -----------
     to the Term Out Date at the per annum rate set forth on Schedule 1.1(A)
     corresponding to the higher of the Company's Debt Ratings on the actual
     daily amount by which the Commitment exceeds the outstanding Loans;

provided, that, if at any time, neither of the Rating Agencies rates the
Company's long-term senior unsecured debt, then the respective percentages set
forth in Column V of Schedule 1.1(A) shall be used to determine the Utilization
Fee and Non-Use Fee, respectively.  Notwithstanding the foregoing, at any time
that the Company's Debt Ratings differ by more than one level, then the rating
level that is one level higher than the lower Debt Rating shall apply.
Initially, the Utilization Fee and Non-Use Fee shall be determined based upon
the respective percentages set forth in Column II of Schedule 1.1(A).
Thereafter, any change in the Utilization Fee and Non-Use Fee resulting from a
change in a Debt Rating shall become effective one Business Day after the
effective date of such change.  The Utilization Fee and Non-Use Fee shall in
each case be calculated for the number of actual days elapsed in the then ending
quarter, and computed on the actual number of days elapsed and a year of 360
days, except that the Utilization Fee and Non-Use Fee for the first calendar
quarter shall be calculated for the period beginning with the Closing Date.  The
Utilization Fee and Non-Use Fee shall in each case be payable in arrears on or
before the fifth (5th) Business Day following the last day of each calendar
quarter, and if the Term Out Date or the Termination Date occurs on any day
other than the last day of a calendar quarter, on or before the fifth (5th)
Business Day following the  Term Out Date or the Termination Date, as the case
may be.

               -----------------------

determined by Bank of America's "prime rate" shall be made on the basis of a
year of 365 or 366 days, as the case may be, and actual days elapsed.  All other
computations of interest shall be made on the basis of a 360-day year and actual
days elapsed.  Interest and fees shall accrue during each period during which
interest or such fees are computed from the first day thereof to the last day
thereof.

     (b) Each determination of an interest rate by the Administrative Agent
shall be conclusive and binding on the Company and the Banks in the absence of
manifest error.

     2.11      Payments by the Company.
               -----------------------

                                       21
<PAGE>

     (a) All payments to be made by the Company shall be made without set-off,
recoupment or counterclaim.  Except as otherwise expressly provided herein, all
payments by the Company shall be made to the Administrative Agent for the
account of the Banks at the Administrative Agent's Payment Office, and shall be
made in dollars and in immediately available funds, no later than 2:00 p.m.
(Dallas time) on the date specified herein.  The Administrative Agent will
promptly distribute to each Bank its Pro Rata Share (or other applicable share
as expressly provided herein) of such payment in like funds as received.  Any
payment received by the Administrative Agent later than 2:00 p.m. (Dallas time)
may be deemed by the Administrative Agent to have been received on the following
Business Day, in which case any applicable interest or fee shall continue to
accrue.  The Administrative Agent shall be entitled to debit any general account
of the Company with the Administrative Agent in the amount of any payment to be
made by the Company when due in order to effect timely payment thereof;
provided, however, that the Administrative Agent shall promptly notify the
Company that its account has been so debited.

     (b) Subject to the provisions set forth in the definition of "Interest
Period" herein, whenever any payment of principal, interest or fees is due on a
day other than a Business Day, such payment shall be made on the following
Business Day, and such extension of time shall in such case be included in the
computation of interest or fees, as the case may be.

     (c) Unless the Administrative Agent receives notice from the Company prior
to the date on which any payment is due to the Banks that the Company will not
make such payment in full as and when required, the Administrative Agent may
assume that the Company has made such payment in full to the Administrative
Agent on such date in immediately available funds and the Administrative Agent
may (but shall not be so required), in reliance upon such assumption, distribute
to each Bank on such due date an amount equal to the amount then due such Bank.
If and to the extent the Company has not made such payment in full to the
Administrative Agent, each Bank shall repay to the Administrative Agent on
demand such amount distributed to such Bank, together with interest thereon at
the Federal Funds Rate for each day from the date such amount is distributed to
such Bank until the date repaid.

     2.12      Payments by the Banks to the Administrative Agent.
               -------------------------------------------------

     (a) Unless the Administrative Agent receives notice from a Bank on or prior
to the Closing Date or, with respect to any Borrowing after the Closing Date, no
later than 12:00 noon (Dallas time) on the date of such Borrowing, that such
Bank will not make available as and when required hereunder to the
Administrative Agent for the account of the Company the amount of that Bank's
Pro Rata Share of the Borrowing, the Administrative Agent may assume that such
Bank has made such amount available to the Administrative Agent in immediately
available funds on the Borrowing Date and the Administrative Agent may (but
shall not be so required), in reliance upon such assumption, make available to
the Company on such date a corresponding amount.  If any Bank shall not have
made its full amount available to the Administrative Agent in immediately
available funds to the extent required by the terms of this Agreement and the
Administrative Agent in such circumstances has made available to the Company
such amount, such Bank shall on the Business Day following such Borrowing Date
make such amount available to the Administrative Agent, together with interest
at the Federal Funds Rate for each day from the date such amount

                                       22
<PAGE>

was made available by the Administrative Agent to the Company until the date on
which such Bank makes such amount available to the Administrative Agent. A
notice of the Administrative Agent submitted to any Bank with respect to amounts
owing under this subsection (a) shall be conclusive, absent manifest error. If
such amount is so made available, such payment to the Administrative Agent shall
constitute such Bank's Loan on the date of Borrowing for all purposes of this
Agreement. If such amount is not made available to the Administrative Agent on
the Business Day following the Borrowing Date, the Administrative Agent will
notify the Company of such failure to fund and, upon demand by the
Administrative Agent, the Company shall pay such amount to the Administrative
Agent for the Administrative Agent's account, together with interest thereon for
each day elapsed since the date of such Borrowing, at a rate per annum equal to
the interest rate applicable at the time to the Loans comprising such Borrowing.

     (b) The failure of any Bank to make any Loan on any Borrowing Date shall
not relieve any other Bank of any obligation hereunder to make a Loan on such
Borrowing Date, but no Bank shall be responsible for the failure of any other
Bank to make the Loan to be made by such other Bank on any Borrowing Date.

3.   TAXES, YIELD PROTECTION AND ILLEGALITY.
     --------------------------------------

     3.1  Taxes.
          -----

     (a)  Any and all payments by the Company to any Bank or the Administrative
Agent under this Agreement or any other Loan Document shall be made free and
clear of, and without deduction or withholding for, any Taxes, unless the
Company is required by law to make such deduction or withholding.  In addition,
the Company shall pay all Other Taxes.

     (b)  The Company agrees to indemnify and hold harmless each Bank and the
Administrative Agent for the full amount of Taxes or Other Taxes (including any
Taxes imposed by any jurisdiction on amounts payable under this Section) paid by
such Bank or the Administrative Agent and any liability (including penalties,
interest, additions to tax and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted; provided, that the Company shall have the right to contest, reasonably
and in good faith to the appropriate Governmental Authorities, whether such
Taxes or Other Taxes were correctly or legally asserted if the Company has set
aside on its books provisions reasonably adequate for the payment of such Taxes
or Other Taxes.  Payment under this indemnification shall be made within thirty
(30) days after the date any Bank or the Administrative Agent makes written
demand therefor.

     (c)  If the Company shall be required by law to deduct or withhold any
Taxes from or in respect of any sum payable hereunder to any Bank or the
Administrative Agent, then:

          (i) the sum payable shall be increased as necessary so that after
     making all required deductions and withholdings (including deductions and
     withholdings applicable to additional sums payable under this Section) such
     Bank or the Administrative Agent, as

                                       23
<PAGE>

     the case may be, receives an amount equal to the sum it would have received
     had no such deductions or withholdings been made;

          (ii)  the Company shall make such deductions and withholdings; and

          (iii) the Company shall pay the full amount deducted or withheld to
     the relevant taxing authority or other authority in accordance with
     applicable law.

Each Bank agrees that if, after the payment by the Company of any such
additional amount, any amount identifiable as a part thereof is subsequently
recovered or used as a credit by such Bank, such Bank shall reimburse the
Company to the extent of the amount so recovered or used. A certificate of any
officer of such Bank setting forth the amount of such Tax or recovery or use and
the basis therefor shall, in the absence of manifest error, be conclusive.

     (d) The provisions of subsections (a), (b) and (c) of this Section 3.1
shall not apply to any Bank which fails to comply with the provisions of Section
11.10 hereof.

     (e) Within thirty (30) days after the date of any payment by the Company of
Taxes or Other Taxes, the Company shall furnish the Administrative Agent the
original or a certified copy of a receipt evidencing payment thereof, or other
evidence of payment satisfactory to the Administrative Agent or the relevant
Bank, as the case may be.

     (f) If the Company is required to pay additional amounts to any Bank or the
Administrative Agent pursuant to subsection (c) of this Section, then such Bank
shall use reasonable efforts (consistent with legal and regulatory restrictions)
to change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by the Company which may thereafter accrue, if such change in
the judgment of such Bank is not otherwise disadvantageous to such Bank.

     3.2  Illegality.
          ----------

     (a) If any Bank determines that the introduction of any Requirement of Law,
or any change in any Requirement of Law, or in the interpretation or
administration of any Requirement of Law, has made it unlawful, or that any
central bank or other Governmental Authority has asserted that it is unlawful,
for any Bank or its applicable Lending Office to make Eurodollar Loans, then, on
notice thereof by such Bank to the Company through the Administrative Agent, any
obligation of such Bank to make Eurodollar Loans shall be suspended until such
Bank notifies the Administrative Agent and the Company that the circumstances
giving rise to such determination no longer exist.

     (b) If a Bank determines that it is unlawful to maintain any Eurodollar
Loan, the Company shall, upon its receipt of notice of such fact and demand from
such Bank (with a copy to the Administrative Agent), prepay in full such
Eurodollar Loans of Bank then outstanding, together with interest accrued
thereon and amounts required under Section 3.4, either on the last day of the
Interest Period thereof, if such Bank may lawfully continue to maintain such
Eurodollar

                                       24
<PAGE>

Loans to such day, or immediately, if such Bank may not lawfully continue to
maintain such Eurodollar Loan. If the Company is required to so prepay any
Eurodollar Loan, then concurrently with such prepayment, the Company shall
borrow from the affected Bank, in the amount of such repayment, a Base Rate
Loan.

     (c) If the obligation of any Bank to make or maintain Eurodollar Loans has
been so terminated or suspended, the Company may elect, by giving notice to such
Bank through the Administrative Agent that all Loans which would otherwise be
made by such Bank as Eurodollar Loans shall be instead Base Rate Loans.

     (d) Before giving any notice to the Agent under this Section, the affected
Bank shall designate a different Lending Office with respect to its Eurodollar
Loans if such designation will avoid the need for giving such notice or making
such demand and will not, in the judgment of the Bank, be illegal or otherwise
disadvantageous to the Bank.

     3.3  Increased Costs and Reduction of Return.
          ---------------------------------------

     (a)  If any Bank determines that, due to either (i) the introduction of or
any change in or in the interpretation of any law or regulation, or (ii) the
compliance by such Bank with any guideline or request from any central bank or
other Governmental Authority (whether or not having the force of law), there
shall be any increase in the cost to such Bank of agreeing to make or making,
funding or maintaining any Eurodollar Loans (which increase is not otherwise
reflected in amounts payable by the Company hereunder), then the Company shall
be liable for, and shall from time to time, upon demand (with a copy of such
demand to be sent to the Administrative Agent), pay to the Administrative Agent
for the account of such Bank, additional amounts as are sufficient, in the good
faith judgment of such Bank, to compensate such Bank for such increased costs.

     (b)  If any Bank shall have determined that (i) the introduction of any
Capital Adequacy Regulation, (ii) any change in the interpretation or
administration of any Capital Adequacy Regulation by any central bank or other
Governmental Authority charged with the interpretation or administration thereof
or (iii) compliance by such Bank (or its Lending Office) or any corporation
controlling such Bank with any Capital Adequacy Regulation, affects or would
affect the amount of capital required or expected to be maintained by such Bank,
such Bank shall promptly after its determination of such occurrence give notice
to the Company of (a) the occurrence thereof, and (b) the additional amount
payable by the Company which in such Bank's reasonable determination will
compensate such Bank or such corporation controlling such Bank for such
reduction and, subject to the further terms of this paragraph, such amount shall
be due and payable by the Company to such Bank at the time of such notice. If,
at the time of notice to the Company that amounts are due under this subsection
3.3(b), the Company and such Bank disagree as to the amounts payable, then the
Company and such Bank shall thereafter attempt to negotiate in good faith an
adjustment to the compensation payable hereunder which will adequately
compensate such Bank for such reduction. If the Company and such Bank are unable
to agree to such adjustment, then, unless the Commitments shall have been
terminated or any amount on which adjustments are to be made under this
subsection 3.3(b) has been prepaid in full, as the

                                       25
<PAGE>

case may be, commencing on the thirty first (31st) day following such notice
(but not earlier than the effective date of such introduction, change or
compliance), the fees payable hereunder shall increase by an amount which will,
in such Bank's reasonable determination, compensate such Bank for such
reduction, such Bank's determination of such amount to be conclusive and binding
on the Company, absent manifest error. In determining such amount, such Bank or
such corporation controlling such Bank may use any reasonable methods of
averaging, allocating or attributing such reduction among their respective
customers.

      3.4 Funding Losses.  The Company shall reimburse each Bank and hold each
          --------------
Bank harmless from any loss or expense which such Bank may sustain or incur as a
consequence of:

          (a) the failure of the Company to borrow, continue or convert a Loan
     after the Company has given (or is deemed to have given) a Notice of
     Borrowing or a Notice of Conversion/Continuation; or

          (b) the prepayment or other payment (including after acceleration
     thereof) of a Eurodollar Loan on a day prior to the last day of the
     relevant Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Eurodollar Loans or from fees payable to
terminate the deposits from which such funds were obtained.  The Company shall
also pay any customary administrative fees charged by such Bank in connection
with the foregoing.

      3.5 Inability to Determine Rates.  If the Administrative Agent determines
          ----------------------------
that for any reason adequate and reasonable means do not exist for determining
the Eurodollar Rate for any requested Interest Period with respect to a proposed
Eurodollar Loan, or that the Adjusted Eurodollar Rate applicable pursuant to
subsection 2.8(a) for any requested Interest Period with respect to a proposed
Eurodollar Loan does not adequately and fairly reflect the cost to the Banks of
funding such Loan, the Administrative Agent will promptly so notify the Company
and each Bank. Thereafter, the obligation of the Banks to make or maintain
Eurodollar Loans hereunder shall be suspended until the Administrative Agent
upon the instruction of the Majority Banks revokes such notice in writing.  Upon
receipt of such notice, the Company may revoke any Notice of Borrowing or Notice
of Conversion/Continuation then submitted by it.  If the Company does not revoke
such Notice, the Banks shall make, convert or continue the Loans, as proposed by
the Company, in the amount specified in the applicable notice submitted by the
Company, but such Loans shall be made, converted or continued as Base Rate Loans
instead of Eurodollar Loans.

      3.6 Certificates of Banks.  Any Bank claiming reimbursement or
          ---------------------
compensation under this Section 3 shall deliver to the Company (with a copy to
the Administrative Agent) a certificate setting forth in reasonable detail the
amount payable to such Bank hereunder and such certificate shall be conclusive
and binding on the Company in the absence of manifest error.

      3.7 Substitution of Banks.  Upon the receipt by the Company from any Bank
          ---------------------
(an "Affected Bank") of a notice pursuant to Section 3.2 that it is unlawful for
such Bank to maintain Eurodollar Loans, or of a claim by such Bank for
compensation under Section 3.3, the Company

                                       26
<PAGE>

may: (i) request one or more of the other Banks to acquire and assume all or
part of such Affected Bank's Loans and Commitment; or (ii) designate a
replacement bank or other financial institution. Any such designation of a
replacement bank or other financial institution under this Section 3.7 shall be
subject to the prior written consent of the Administrative Agent (which consent
shall not be unreasonably withheld). Nothing in this Section 3.7 is intended or
shall be deemed to require any Affected Bank to accept less than payment in full
of the aggregate then outstanding principal balance of the Loans made by such
Affected Bank (together with then accrued interest and fees payable with respect
thereto and all other amounts payable to such Bank hereunder) in connection with
the replacement of such Affected Bank by any other Person hereunder.

      3.8 Survival.  The agreements and obligations of the Company in this
          --------
Section 3 shall survive the payment of all other Obligations and the termination
of this Agreement.

Company, nor the Parent, and thereafter, except in the case of a lease, the
predecessor corporation shall be relieved of their respective obligations and
covenants under this Agreement or any other Loan Document, as the case may be.

     (c)  The provisions of subsections 7.7(a) and (b) shall not apply to a
concurrent merger of the Company into the Parent or a concurrent merger of the
Parent into the Company, provided that each of the following conditions are met:
(i) the Company gives the Administrative Agent no less than five (5) Business
Days prior written notice of such merger; (ii) the merger involves no Persons
other than the Company and the Parent; (iii) immediately after giving effect to
such Merger, no Event of Default, and no event which, after notice, or lapse of
time, or both, would become an Event of Default, shall have happened and be
continuing; (iv) as the result of such merger or consolidation, none of the
properties or assets of the Company, the Parent or any of their respective
Subsidiaries would become subject to a Lien which would not be permitted by this
Agreement; and (v) the Company delivers to the Administrative Agent a
certificate executed by its President or any of its Vice Presidents and its
Secretary stating that all conditions of this subsection 7.7(c) relating to such
merger have been complied with.  The succeeding corporation of such merger shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company and the Parent under this Agreement or any other Loan Document, with
the same effect as if such successor corporation had been named as the Company
and the Parent; provided, that neither the Company nor the Parent, and
thereafter, any predecessor corporation, if any, shall be relieved of their
respective obligations and covenants under this Agreement, the Notes or the
Guaranty.

     7.8  Changes in Business.  The Company will not, and it will not permit any
          -------------------
of its Subsidiaries, to make any material change in its business, or in the
nature of its operations, or liquidate or dissolve itself (or suffer any
liquidation or dissolution).

     7.9  ERISA.  The Company shall not directly or indirectly, and will not
          -----
permit any member of any Controlled Group to directly or indirectly, enter into
any new Plan, Welfare Plan or Multi-employer Plan without complying with the
notification obligations contained in Section 6.14 hereof.

8.   EVENTS OF DEFAULT; ACCELERATION.
     -------------------------------

     Any of the following shall constitute an "Event of Default":

                                       40
<PAGE>

     (a)  the Company shall default in any payment of any principal amount
outstanding hereunder or under any Notes when due and payable, whether at
maturity or at any date fixed for payment or prepayment or by declaration or
otherwise; or

     (b)  the Company shall fail to pay any interest with respect to principal
outstanding hereunder, or any fee pursuant to the terms of Section 2.9, within
five (5) Business Days after the date due and payable, whether at maturity or at
any date fixed for payment or prepayment or by declaration or otherwise, other
than due to a failure of the Administrative Agent to charge an account of the
Company having a sufficient credit balance; or

     (c)  there shall be a default in the performance of or compliance with any
covenant in Section 7 hereof; or

     (d)  the Company shall default in the performance of or compliance with any
term contained herein (other than those referred to above in this Section 8),
and such default shall not have been remedied within thirty (30) Business Days
after the occurrence thereof; or

     (e)  any representation or warranty made in writing by or on behalf of the
Company herein, in any other Loan Document or in connection with any of the
transactions contemplated hereby shall prove to have been false or incorrect in
any material respect on the date as of which made; or

     (f)  the Parent, the Company or any of their respective Subsidiaries shall
default (as principal or guarantor or other surety) in the payment of any
principal or premium, if any, of, or interest or fees on, any other Indebtedness
to any Bank, or any other Indebtedness in respect of borrowed money in an
aggregate principal amount of $10,000,000 or more (which default is in payment
thereof at its stated maturity or shall result in such Indebtedness becoming or
being declared due prior to the scheduled maturity thereof) or if the Parent,
the Company or any of their respective Subsidiaries shall fail to comply (and
such failure to comply has not been cured or waived) with any of the terms of
any document evidencing any such Indebtedness or any mortgage, pledge,
assignment, indenture or other document relating thereto, and as a consequence
of any of the foregoing, the holder of such Indebtedness shall have the right to
declare all amounts payable with respect thereto to be due and payable by reason
of such default prior to the scheduled maturity thereof or demand payment of all
amounts payable in respect of any Indebtedness payable on demand; or

     (g)  if the Parent, the Company or any of their respective Subsidiaries
makes an assignment for the benefit of creditors, or petitions or applies for
the appointment of a liquidator or receiver of or for any of such Persons, or of
any substantial part of the respective assets thereof, or commences any
proceeding relating to any of such Persons under any bankruptcy, reorganization,
arrangement, insolvency, readjustment of debt, dissolution or liquidation or
similar law of any jurisdiction, now or hereafter in effect; or

     (h)  if any such petition or application is filed or any such proceeding is
commenced against the Parent, the Company or any of their respective
Subsidiaries, and any of such Persons

                                       41
<PAGE>

indicates its approval thereof, consents thereto or acquiesces therein, or any
such petition, application or proceeding remains undischarged for thirty (30)
days, or an order is entered appointing any such liquidator or receiver, or
adjudicating the Parent, the Company or any of their respective Subsidiaries
bankrupt or insolvent, or approving a petition in any such proceeding; or

     (i)  any order is entered in any proceeding by or against the Parent, the
Company or any of their respective Subsidiaries decreeing or permitting the
dissolution or split-up of any of such Persons or the winding-up of the affairs
of any of such Persons; or

     (j)  there shall be in force, undischarged, unsatisfied and unstayed, for
more than thirty (30) days, whether or not consecutive, any final judgment (from
which all appeals have been taken and determined or as to which all time for the
taking of appeals has lapsed) in excess of $1,000,000 in the aggregate against
the Parent, the Company or any of their respective Subsidiaries; or

     (k)  any representation or warranty made in writing by or on behalf of the
Parent in the Guaranty, in any other Loan Document or in connection with any of
the transactions contemplated hereby or thereby shall prove to have been false
or incorrect in any material respect on the date as of when made, or if the
Parent shall default in respect of any of its obligations under the Guaranty or
if the Guaranty shall cease to be in full force and effect without the prior
written consent of the Banks; or

     (l)  the Parent shall at any time own, beneficially, and of record, less
than a majority of all of the issued and outstanding shares of capital stock of
the Company having ordinary voting rights for the election of directors.

9.   NOTICE AND WAIVERS OF DEFAULT.
     -----------------------------

     9.1  Notice of Default.  If any Person shall give any notice or take any
          -----------------
other action in respect of a claimed default (whether or not constituting an
Event of Default) under this Agreement or any other document as to which the
Parent, the Company or any of their respective Subsidiaries is a party or
obligor, whether as principal or surety, the Company shall forthwith give
written notice thereof to the Administrative Agent (which shall promptly give
notice thereof to each of the Banks), describing the notice or action and the
nature of the claimed default.

     9.2  Waivers of Default.  Any Default or Event of Default may be waived as
          ------------------
provided in Section 24.  Any Default or Event of Default so waived shall be
deemed to have been cured and to be not continuing; but no such waiver shall
extend to or affect any subsequent like default or impair any rights arising
therefrom.

10.  REMEDIES ON DEFAULT.
     -------------------

     10.1 Rights of Banks.  If any Event of Default occurs, the Administrative
          ---------------
Agent shall at the request of, or may with the consent of, the Majority Banks,

                                       42
<PAGE>

     (a)  declare the Commitment of each Bank to make Loans to be terminated,
whereupon such Commitments shall be terminated;

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

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

provided, that upon the occurrence of any event specified in subsection (g), (h)
or (i) of Section 8, the obligation of each Bank to make Loans shall
automatically terminate and the unpaid principal amount of all outstanding Loans
and all interest and other amounts as aforesaid shall automatically become due
and payable without further act of the Administrative Agent or any Bank.

     10.2 Set-off; Sharing.
          ----------------

      (a) Set-off.  In addition to any rights and remedies of the Banks provided
          -------
by applicable law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Company, any such notice being waived by the Company to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Bank to or for the credit or
the account of the Company against any and all Obligations owing to such Bank,
now or hereafter existing, irrespective of whether or not the Administrative
Agent or such Bank shall have made demand under this Agreement or any Loan
Document and although such Obligations may be contingent or unmatured.  Each
Bank agrees promptly to notify the Company and the Administrative Agent after
any such set-off and application made by such Bank; provided, that the failure
to give such notice shall not affect the validity of such set-off and
application.

      (b) Sharing.  If, other than as expressly provided elsewhere herein, any
          -------
Bank shall obtain on account of the Loans made by it any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or
otherwise) in excess of its Pro Rata Share, such Bank shall immediately (a)
notify the Administrative Agent of such fact, and (b) purchase from the other
Banks such participations in the Loans made by them as shall be necessary to
cause such purchasing Bank to share the excess payment pro rata with each of
them; provided, that if all or any portion of such excess payment is thereafter
recovered from the purchasing Bank, such purchase shall to that extent be
rescinded and each other Bank shall repay to the purchasing Bank the purchase
price paid therefor, together with an amount equal to such paying Bank's ratable
share (according to the proportion of (i) the amount of such paying Bank's
required repayment to (ii) the total amount so recovered from the purchasing
Bank) of any interest or other amount paid or payable by the purchasing Bank in
respect of the total amount so recovered.  The Company agrees that any Bank so
purchasing a participation from another Bank may, to the fullest extent

                                       43
<PAGE>

permitted by law, exercise all its rights of payment (including the right of
set-off, but subject to this Section 10) with respect to such participation as
fully as if such Bank were the direct creditor of the Company in the amount of
such participation.  The Administrative Agent will keep records (which shall be
conclusive and binding in the absence of manifest error) of participations
purchased under this subsection 10.2(b) and will in each case notify the Banks
following any such purchases or repayments.

11.  THE ADMINISTRATIVE AGENT.
     ------------------------

     11.1 Appointment and Authorization.  Each Bank hereby irrevocably (subject
          -----------------------------
to Section 11.9) appoints, designates and authorizes the Administrative Agent to
take such action on its behalf under the provisions of this Agreement and each
other Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Administrative Agent shall not have
any duties or responsibilities, except those expressly set forth herein, nor
shall the Administrative Agent have or be deemed to have any fiduciary
relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" herein and in the other Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary
or other implied (or express) obligations arising under agency doctrine of any
applicable law. Instead, such term is used merely as a matter of market custom,
and is intended to create or reflect only an administrative relationship between
independent contracting parties.

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

     11.3 Liability of Administrative Agent.  None of the Administrative
          ---------------------------------
Agent-Related Persons shall (i) be liable for any action taken or omitted to be
taken by any of them under or in connection with this Agreement or any other
Loan Document or the transactions contemplated hereby (except for its own gross
negligence or willful misconduct), or (ii) be responsible in any manner to any
of the Banks for any recital, statement, representation or warranty made by the
Parent, the Company or any of their respective Subsidiaries, or any officer
thereof, contained in this Agreement or in any other Loan Document, or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Administrative Agent under or in connection with, this
Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of the Company or any other party to any Loan
Document to perform its obligations hereunder or thereunder.  No Administrative
Agent-Related Person shall be under any obligation to any Bank to ascertain or
to inquire as to the observance or performance of any of the

                                       44
<PAGE>

agreements contained in, or conditions (other than delivery to the
Administrative Agent of the documents described in subsections 4.1(a), (b) and
(d)) of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of the Parent, the Company or any of their
respective Subsidiaries.

     11.4 Reliance by Administrative Agent.
          --------------------------------

     (a)  The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to the
Company), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Majority Banks as it deems appropriate and, if it so requests, it shall first be
indemnified to its satisfaction by the Banks against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action.  The Administrative Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Agreement or any other Loan
Document in accordance with a request or consent of the Majority Banks (or when
expressly required hereby or thereby, all the Banks) and such request and any
action taken or failure to act pursuant thereto shall be binding upon all of the
Banks.

     (b)  For purposes of determining compliance with the conditions specified
in Section 4.1, each Bank that has executed this Agreement shall be deemed to
have consented to, approved or accepted or to be satisfied with, each document
or other matter either sent by the Administrative Agent to such Bank for
consent, approval, acceptance or satisfaction, or required thereunder to be
consented to or approved by or acceptable or satisfactory to such Bank.

     11.5 Notice of Default.  The Administrative Agent shall not be deemed to
          -----------------
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Banks,
unless the Administrative Agent shall have received written notice from a Bank
or the Company referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". The
Administrative Agent will promptly notify the Banks of its receipt of any such
notice. The Administrative Agent shall take such action with respect to such
Default or Event of Default as may be requested by the Majority Banks in
accordance with Section 10.1; provided, that unless and until the Administrative
Agent has received any such request, the Administrative Agent may (but shall not
be obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable or in the
best interest of the Banks.

     11.6 Credit Decision.  Each Bank acknowledges that none of the
          ---------------
Administrative Agent-Related Persons has made any representation or warranty to
it, and that no act by the Administrative Agent hereinafter taken, including any
review of the affairs of the Parent, the

                                       45
<PAGE>

Company and their respective Subsidiaries, shall be deemed to constitute any
representation or warranty by any Administrative Agent-Related Person to such
Bank. Each Bank represents to the Administrative Agent that it has,
independently and without reliance upon any Administrative Agent-Related Person
and based on such documents and information as it has deemed appropriate, made
its own appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Parent, the
Company and their respective Subsidiaries, and all applicable bank regulatory
laws relating to the transactions contemplated hereby, and made its own decision
to enter into this Agreement and to extend credit to the Company hereunder. Each
Bank also represents that it will, independently and without reliance upon any
Administrative Agent-Related Person and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Agreement and the other Loan Documents, and to make such investigations as it
deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of the Company.
Except for notices, reports and other documents expressly herein required to be
furnished to the Banks by the Administrative Agent, the Administrative Agent
shall not have any duty or responsibility to provide any Bank with any credit or
other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of the Parent, the Company, or
any of their respective Subsidiaries, which may come into the possession of any
of the Administrative Agent-Related Persons.

     11.7 Indemnification of Administrative Agent.  Whether or not the
          ---------------------------------------
transactions contemplated hereby are consummated, the Banks shall indemnify upon
demand the Administrative Agent-Related Persons (to the extent not reimbursed by
or on behalf of the Company and without limiting the obligation of the Company
to do so), pro rata, from and against any and all Indemnified Liabilities;
provided, that no Bank shall be liable for the payment to the Administrative
Agent-Related Persons of any portion of such Indemnified Liabilities to the
extent resulting from such Person's gross negligence or willful misconduct;
provided further, that no action taken in accordance with the directions of the
Majority Banks shall be deemed to constitute gross negligence or willful
misconduct for purposes of this Section 11.7.  Without limitation of the
foregoing, each Bank shall reimburse the Administrative Agent upon demand for
its ratable share of any costs or out-of-pocket expenses (including Attorney
Costs) incurred by the Administrative Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement, any other
Loan Document, or any document contemplated by or referred to herein, to the
extent that the Administrative Agent is not reimbursed for such expenses by or
on behalf of the Company.  The undertaking in this Section 11.7 shall survive
the payment of all Obligations hereunder and the resignation or replacement of
the Administrative Agent.

     11.8 Agents in Individual Capacity.  Each of the Agents and its affiliates
          -----------------------------
may make loans to, issue letters of credit for the account of, accept
deposits from, acquire equity interests in and generally engage in any kind of
banking, trust, financial advisory, underwriting or other business with the
Parent, the Company and their respective Subsidiaries as though such Person were
not an Agent hereunder and without notice to or consent of the other Agents or
the Banks.

                                       46
<PAGE>

The Banks acknowledge that, pursuant to such activities, each Agent and its
affiliates may receive information regarding the Parent, the Company or their
respective Subsidiaries (including information that may be subject to
confidentiality obligations in favor of any of such Persons) and acknowledge
that such Agent shall be under no obligation to provide such information to
them. With respect to their respective Loans, the Syndication Agent and the
Documentation Agent shall have the same rights and powers under this Agreement
and the other Loan Documents as any other Bank and may exercise the same as
though such Persons were not an Agent or an affiliate of an Agent, as the case
may be.

     11.9  Successor Administrative Agent.  The Administrative Agent may
           ------------------------------
resign as Administrative Agent upon 30 days' notice to the Banks and the
Company.  If the Administrative Agent resigns under this Agreement, the Majority
Banks shall appoint from among the Banks a successor administrative agent for
the Banks, which successor administrative agent shall be approved by the Company
at all times other than during the existence of an Event of Default (which
approval of the Company shall not be unreasonably withheld or delayed).  If no
successor administrative agent is appointed prior to the effective date of the
resignation of the Administrative Agent, the Administrative Agent may appoint,
after consulting with the Banks and the Company, a successor administrative
agent from among the Banks.  Upon the acceptance of its appointment as successor
administrative agent hereunder, such successor administrative agent shall
succeed to all the rights, powers and duties of the retiring Administrative
Agent and the term "Administrative Agent" shall mean such successor
administrative agent and the retiring Administrative Agent's appointment, powers
and duties as Administrative Agent shall be terminated. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this Section 11 and Section 15 shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was Administrative Agent
under this Agreement.  If no successor agent has accepted appointment as
Administrative Agent by the date which is thirty (30) days following a retiring
Administrative Agent's notice of resignation, the retiring Administrative
Agent's resignation shall nevertheless thereupon become effective and the Banks
shall perform all of the duties of the Administrative Agent hereunder until such
time, if any, as the Majority Banks appoint a successor agent as provided for
above.

     11.10 Withholding Tax.  Each Bank that is a "foreign corporation,
           ---------------
partnership or trust" within the meaning of the Code (a "Foreign Lender") shall
                                                         --------------
deliver to the Administrative Agent, prior to receipt of any payment subject to
withholding under the Code (or after accepting an assignment of an interest
herein), two duly signed completed copies of either IRS Form W-8BEN or any
successor thereto (relating to such Person and entitling it to an exemption
from, or reduction of, withholding tax on all payments to be made to such Person
by the Company pursuant to this Agreement) or IRS Form W-8ECI or any successor
thereto (relating to all payments to be made to such Person by the Company
pursuant to this Agreement) or such other evidence satisfactory to the

                                       47
<PAGE>

Company and the Administrative Agent that such Person is entitled to an
exemption from, or reduction of, U.S. withholding tax. Thereafter and from time
to time, each such Person shall (a) promptly submit to the Administrative Agent
such additional duly completed and signed copies of one of such forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may then be available under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
Company and the Administrative Agent of any available exemption from or
reduction of, United States withholding taxes in respect of all payments to be
made to such Person by the Company pursuant to this Agreement, (b) promptly
notify the Administrative Agent of any change in circumstances which would
modify or render invalid any claimed exemption or reduction, and (c) take such
steps as shall not be materially disadvantageous to it, in the reasonable
judgment of such Bank, and as may be reasonably necessary (including the re-
designation of its Lending Office) to avoid any requirement of applicable Laws
that the Company make any deduction or withholding for taxes from amounts
payable to such Person. If such Person fails to deliver the above forms or other
documentation, then the Administrative Agent may withhold from any interest
payment to such Person an amount equivalent to the applicable withholding tax
imposed by Sections 1441 and 1442 of the Code, without reduction. If any
Governmental Authority asserts that the Administrative Agent did not properly
withhold any tax or other amount from payments made in respect of such Person,
such Person shall indemnify the Administrative Agent therefor, including all
penalties and interest, any taxes imposed by any jurisdiction on the amounts
payable to the Administrative Agent under this Section, and costs and expenses
(including Attorney Costs) of the Administrative Agent. The obligation of the
Banks under this Section shall survive the payment of all Obligations and the
resignation or replacement of the Administrative Agent.

     11.11 Syndication Agent and Documentation Agent.  Neither the Syndication
           -----------------------------------------
Agent nor the Documentation Agent shall have or be deemed to have any right,
power, obligation, liability, responsibility or duty under this Agreement by
virtue of such titles other than those applicable to all Banks as such. Without
limiting the foregoing, neither the Syndication Agent nor the Documentation
Agent shall have or be deemed to have any fiduciary relationship with any Bank.
Each Bank acknowledges that it has not relied, and will not rely, on the
Syndication Agent or the Documentation Agent in deciding to enter into this
Agreement or in taking or not taking action hereunder.

12.  ASSIGNMENT; PARTICIPATION.
     -------------------------

     12.1  Assignments.
           -----------

     (a)   Any Bank may, with the written consent of the Company (at all times
other than during the existence of an Event of Default) and the Administrative
Agent, which consents shall not be unreasonably withheld, at any time assign and
delegate to one or more Eligible Assignees (provided that no written consent of
the Company or the Administrative Agent shall be required in connection with any
assignment and delegation by a Bank to another Bank or to an Eligible Assignee
that is an affiliate of the assignor Bank) (each an "Assignee") all, or any
                                                     --------
ratable part of all, of the Loans, the Commitment and the other rights and
obligations of such Bank hereunder, in a minimum amount of $10,000,000; provided
that such minimum amount shall not apply in the case of an assignment of the
entire remaining amount of the assignor Bank's Commitment and the Loans at the
time owing to it or in the case of an assignment by a Bank to another Bank or to
an Eligible Assignee that is an affiliate of the assignor Bank; provided further
that the Company and the Administrative Agent may continue to deal solely and
directly with such Bank in connection with the interest so assigned to an
Assignee until (i) written notice of such assignment, together with payment
instructions, addresses and related information with respect to the Assignee,

                                       48
<PAGE>

shall have been given to the Company and the Administrative Agent by such Bank
and the Assignee; (ii) such Bank and its Assignee shall have delivered to the
Company and the Administrative Agent an Assignment and Acceptance Agreement in
substantially the form of Exhibit F ("Assignment and Acceptance"), together with
                                      -------------------------
any Note or Notes subject to such assignment, and (iii) the assignor Bank or
Assignee has paid to the Administrative Agent a processing fee in the amount of
$3,500.  From and after the date that the Administrative Agent notifies the
assignor Bank that it has received (and provided its consent with respect to) an
executed Assignment and Acceptance and payment of the above-referenced
processing fee, (I) the Assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, shall have the rights and obligations of a
Bank under the Loan Documents, and (II) the assignor Bank shall, to the extent
that rights and obligations hereunder and under the other Loan Documents have
been assigned by it pursuant to such Assignment and Acceptance, relinquish its
rights and be released from its obligations under the Loan Documents.

     (b)   Within five (5) Business Days after its receipt of notice by the
Administrative Agent that it has received an executed Assignment and Acceptance
and payment of the processing fee (and provided that it consents to such
assignment in accordance with subsection 12.1(a)), the Company shall execute and
deliver to the Administrative Agent, a new Note evidencing such Assignee's
assigned Loans and Commitment and, if the assignor Bank has retained a portion
of its Loans and Commitment and so requests, a replacement Note evidencing such
retained Loans and Commitment (such Notes to be in substitution for, but not in
payment of, the Note held by such Bank). Immediately upon payment of the
processing fee under the Assignment and Acceptance, this Agreement shall be
deemed to be amended to the extent, but only to the extent, necessary to reflect
the addition of the Assignee and the resulting adjustment of the Commitments
arising therefrom. The Commitment allocated to each Assignee shall reduce such
Commitment of the assigning Bank pro tanto.

     12.2  Participations.  Any Bank may at any time sell to one or more
           --------------
commercial banks or other Persons not affiliates of the Company (a
"Participant") participating interests in any Loans, the Commitment of that Bank
and the other interests of that Bank (the "originating Bank") hereunder and
under the other Loan Documents; provided, that (i) the originating Bank's
obligations under this Agreement shall remain unchanged, (ii) the originating
Bank shall remain solely responsible for the performance of such obligations,
(iii) the Company and the Administrative Agent shall continue to deal solely and
directly with the originating Bank in connection with the originating Bank's
rights and obligations under this Agreement and the other Loan Documents, and
(iv) no Bank shall transfer or grant any participating interest under which the
Participant has rights to approve any amendment to, or any consent or waiver
with respect to, this Agreement or any other Loan Document, except to the extent
such amendment, consent or waiver would require unanimous consent of the Banks
as described in the first proviso to Section 24. In the case of any such
                    -------------
participation, the Participant shall not have any rights under this Agreement,
or any other Loan Documents, and all amounts payable by the Company hereunder
shall be determined as if such Bank had not sold such participation, except that
if amounts outstanding under this Agreement are due and unpaid, or shall have
been declared or shall have become due and payable upon the occurrence of an
Event of Default, each Participant shall be

                                       49
<PAGE>

deemed to have the right of set-off in respect of its participating interest in
amounts owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as a Bank under this Agreement.

     A Participant shall not be entitled to receive any greater payment under
Section 3.1 or 3.3 than the originating Bank would have been entitled to receive
with respect to the participation sold to such Participant, unless the sale of
the participation to such Participant is made with the Company's prior written
consent.  A Participant that would be a Foreign Lender if it were a Bank shall
not be entitled to the benefits of Section 3.1 unless the Company is notified of
the participation sold to such Participant and such Participant agrees, for the
benefit of the Company and the Administrative Agent, to comply with Section
10.11 as though it were a Bank.

     Notwithstanding any other provision in this Agreement, any Bank 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 any Note held by it in favor of any
Federal Reserve Bank in accordance with Regulation A of the FRB or U.S. Treasury
Regulation 31 CFR (S)203.14, and such Federal Reserve Bank may enforce such
pledge or security interest in any manner permitted under applicable law.

                                       51
<PAGE>

expenses and disbursements (including reasonable Attorney Costs) of any kind or

Administrative Agent or replacement of any Bank) be imposed on, incurred by or
asserted against any such Person in any way relating to or arising out of this

     Each and every right granted to the Banks and the Administrative Agent
hereunder or under any other document delivered hereunder or in connection
herewith, or allowed them by law or equity, shall be cumulative and may be
exercised from time to time.  No failure on the part of any Bank or the
Administrative Agent to exercise, and no delay in exercising, any right shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right preclude any other or future exercise thereof or the exercise of any other
right.  The due payment and performance of the Company's Obligations under this
Agreement shall be without regard to any counterclaim, right of offset or any
other claim whatsoever which the Company may have against the Banks and the
Administrative Agent and without regard to any other obligation of any nature
whatsoever which the Banks and the Administrative Agent may have to the Company,

connection with the Loans.

18.  SURVIVAL OF COVENANTS.
     ---------------------

     All covenants, agreements, representations and warranties made herein and
in any document delivered by or on behalf of the Company pursuant hereto are
material and shall be deemed to have been relied upon by the Administrative
Agent and the Banks, notwithstanding any

                                       52
<PAGE>

investigation heretofore or hereafter made by the Administrative Agent or the
Banks, and shall survive the making by the Banks of the Loans as herein

Obligations remain outstanding and unpaid. All statements contained in any
certificate or other document delivered to the Administrative Agent or the Banks
at any time by or on behalf of the Company pursuant hereto or in connection with

warranties by the Company hereunder.

provision hereof shall be held invalid or unenforceable in whole or in part in
any jurisdiction, then such invalidity or unenforceability shall affect only
such clause or provision, or part thereof, in such jurisdiction and shall not in
any manner affect such clause or provision in any other jurisdiction, or any
other clause or provision in this Agreement in any jurisdiction.

20.  NOTICE.
     ------

     (a)  All notices, requests and other communications shall be in writing
(including by facsimile transmission) and mailed, faxed or delivered, to the
address, facsimile number or (subject to subsection (e) below) electronic mail
specified for notices on Schedule 20; or, as directed to the Company or the
Administrative Agent, to such other address as shall be designated by such party

(next-day) delivery, or transmitted in legible form by facsimile machine and
receipt has been confirmed by telephone, respectively, or if mailed, upon the
third Business Day after the date deposited into the U.S. mail, or if delivered,

notices pursuant to Section 2 or Section 11 shall not be effective until
actually received by the Administrative Agent.

     (c)  Any agreement of the Administrative Agent and the Banks herein to
receive certain notices by telephone or facsimile is solely for the convenience
and at the request of the Company. The Administrative Agent and the Banks shall
be entitled to rely on the authority of any Person purporting to be a Person
authorized by the Company to give such notice and the Administrative Agent and
the Banks shall not have any liability to the Company or other Person on account
of any action taken or not taken by the Administrative Agent or the Banks in
reliance upon such telephonic or facsimile notice.  The obligation of the
Company to repay the Loans shall not be affected in any way or to any extent by
any failure by the Administrative Agent and the Banks to receive written

Administrative Agent and the Banks of a confirmation which is at variance with
the terms understood by the Administrative Agent and the Banks to be contained
in the telephonic or facsimile notice.

     (d) Loan Documents may be transmitted or signed by facsimile.  The
effectiveness of any such documents and signatures shall, subject to applicable
law, have the same force and effect as manually-signed originals and shall be
binding on the Company, the Administrative Agent and the Banks.  The
Administrative Agent may also require that any such documents and signatures be
confirmed by a manually-signed original thereof; provided, that the failure to
request or deliver the same shall not limit the effectiveness of any facsimile
document or signature.

     (e) Electronic mail and internet and intranet websites may be used only to
distribute routine communications, such as financial statements and other
information, and to distribute Loan Documents for execution by the parties
thereto, and may not be used for any other purpose.

 21. GOVERNING LAW.
     -------------

     THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAW OF THE STATE OF ILLINOIS APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED
ENTIRELY WITHIN SUCH STATE; PROVIDED THAT THE ADMINISTRATIVE AGENT AND EACH BANK
SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

 22. MISCELLANEOUS.
     -------------

     The rights and remedies herein expressed are cumulative and not exclusive
of the other rights which the Banks would otherwise have.  Any documents

exhibit shall be substantially in such form with such changes therefrom, if any,
as may be approved by the Majority Banks and the Company.  The captions in this
Agreement are for convenience of reference only and shall not define or limit
the provisions hereof. This Agreement, and any amendment, consent or waiver
executed and delivered hereunder or in connection herewith or with any other
Loan Document, may be executed in separate counterparts, each of which when so
executed and delivered shall be an original, but all of which together shall
constitute one document.  In proving this Agreement, it shall not be necessary
to produce or account for more than one Agreement, executed by each of the
parties hereto.

 23. ENTIRE AGREEMENT.
     ----------------

     THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT
BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO
UNWRITTEN AGREEMENTS BETWEEN THE PARTIES RELATING TO ANY OF THE PROVISIONS OF
THIS AGREEMENT.

 24. CONSENTS, AMENDMENTS AND WAIVERS.
     --------------------------------

     No amendment or waiver of any provision of this Agreement or any other Loan
Document, and no consent with respect to any departure by the Company therefrom,
shall be effective unless

                                      54
<PAGE>

the same shall be in writing and signed by the Majority Banks (or by the
Administrative Agent at the written request of the Majority Banks) and the
Company (or, in the case of the Guaranty, the Parent) and acknowledged by the
Administrative Agent, and then any such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given;
provided, that no such waiver, amendment, or consent shall, unless in writing
and signed by all of the Banks and the Company (or, in the case of the Guaranty,
the Parent) and acknowledged by the Administrative Agent, do any of the
following:

     (a) increase or extend the Commitment of any Bank (or reinstate any
Commitment terminated pursuant to Section 10.1);

     (b) postpone or delay any date fixed by this Agreement or any other Loan
Document for any payment of principal, interest, fees or other amounts due to
the Banks (or any of them) hereunder or under any other Loan Document;

     (c) reduce the principal of, or the rate of interest specified herein on
any Loan, or (subject to clause (ii) below) any fees or other amounts payable
hereunder or under any other Loan Document;

     (d) change the percentage of the Commitments or of the aggregate unpaid
principal amount of the Loans which is required for the Banks or any of them to

for consent or other action by all Banks;

     (f) release, amend or otherwise modify the Guaranty;

and, provided, further, that (i) no amendment, waiver or consent shall, unless
in writing and signed by the Administrative Agent in addition to the Majority
Banks or all the Banks, as the case may be, affect the rights or duties of the
Administrative Agent under this Agreement or any other Loan Document, and (ii)
the Fee Letter may be amended, or rights or privileges thereunder waived, in a
writing executed by the parties thereto.

 25. OPTIONAL INCREASE IN COMMITMENTS.
     --------------------------------

     The Company may, from time to time prior to Term Out Date, by means of a
letter to the Administrative Agent substantially in the form of Exhibit G,
request that the Commitment be increased by (a) increasing the Pro Rata Share of
the Commitment of one or more Banks which have agreed to such increase and/or
adding one or more commercial banks or other Persons as a party hereto with a
Pro Rata Share in an amount agreed to by any such commercial bank or other
Person; provided that (i) no commercial bank or other Person shall be added as a
party hereto without the written consent of the Administrative Agent (which
consent shall not be unreasonably withheld or delayed); (ii) in no event shall
the Commitment exceed $110,000,000 without the written consent of all Banks; and
(iii) the Commitment under (and as defined in) the Five-Year Agreement shall be
increased in proportion to the increased Commitment under this Agreement
(provided that the Five-Year Agreement is then still in effect).  Any increase
in the Commitment pursuant to this Section 25 shall be effective three Business
Days after the date on which the Administrative Agent has received and accepted
the applicable increase letter in the form of Annex 1 to Exhibit G (in the case
of an increase in the Commitment of an existing Bank) or assumption letter in
the form of Annex 2 to Exhibit G (in the case of the addition of a commercial
bank or other Person as a new Bank).  The Administrative Agent shall promptly
notify the Company and the Banks of any increase in the amount of the Commitment
pursuant to this Section 25 and of the Pro Rata Share of each Bank after giving
effect thereto.  The Company shall prepay any Loans outstanding on the effective
date of any increase in the amount of the Commitment pursuant to this Section 25
(and pay additional amounts required pursuant to Section 3.4) to the extent
necessary to keep the outstanding Loans ratable with any revised Pro Rata Share
arising from any nonratable increase in the Commitment under this Section.  This
Section shall supersede any provisions in Section 24 to the contrary.

                               CREDIT AGREEMENT
                        DATED AS OF SEPTEMBER 28, 2000

                               FORM OF GUARANTY
                               ----------------

     GUARANTY, dated as of September 28, 2000 by XTRA CORPORATION, a Delaware
corporation (the "Guarantor"), in favor of each of the Banks (as such term is
defined in the Credit Agreement referred to below). In consideration of the
Banks extending time, credit or banking facilities or accommodations to XTRA,
INC., a Maine corporation, and its successors (the "Company"), the Guarantor
agrees as follows:

     1.   GUARANTY OF PAYMENT AND PERFORMANCE. The Guarantor hereby irrevocably,
absolutely and unconditionally guarantees to the Banks the full and punctual
payment when due (whether at maturity, by acceleration or otherwise), and the
performance, of all liabilities, agreements and other obligations of the Company
to the Banks, whether direct or indirect, absolute or contingent, due or to
become due, secured or unsecured, now existing or hereafter arising
(collectively, the "Obligations") under that certain Credit Agreement of even
date herewith (as extended, renewed, amended, restated or otherwise supplemented
from time to time, the "Credit Agreement") among the Company, the Banks from
time to time parties thereto, and Bank of America, N.A., as Administrative
Agent, Fleet National Bank, as Syndication Agent and Bank One, NA (Main Office
Chicago), as Documentation Agent, respectively, for the Banks thereunder.
Capitalized terms used herein without definition which are defined in the Credit
Agreement shall have the same meanings herein as in the Credit Agreement. This
Guaranty is an absolute, unconditional and continuing guaranty of the full and
punctual payment and performance of the Obligations and not of their
collectibility only and is in no way conditioned upon any requirement that the
Banks first attempt to collect any of the Obligations from the Company or resort
to any security or other means of obtaining payment of the Obligations which the
Banks may now have or may acquire after the date hereof, or upon any other
contingency whatsoever. Should the Company default in the full and punctual
payment or performance of any of the Obligations, the liabilities and
obligations of the Guarantor hereunder shall become immediately due and payable,
without demand or notice of any nature, all of which are expressly waived by the
Guarantor. Payments by the Guarantor hereunder may be required by the Banks on
any number of occasions.

     2.   GUARANTOR'S AGREEMENT TO PAY.  The Guarantor further agrees, as the
principal obligor and not as a guarantor only, to pay to the Administrative
Agent for the benefit of the Banks, on demand, all costs and expenses (including
court costs and reasonable Attorney Costs) incurred or expended by the Banks in
connection with the Obligations, this Guaranty and the enforcement thereof.

     3.   LIMITED GUARANTY. The liability of the Guarantor shall be limited to
the Obligations and the obligations of the Guarantor described in Section 2
hereof.

                                      H-1
<PAGE>

     4.   WAIVERS BY GUARANTOR; BANKS' FREEDOM TO ACT. The Guarantor agrees that
the Obligations will be paid and performed strictly in accordance with their
respective terms regardless of any law, regulation or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of any Bank
with respect thereto. The Guarantor waives, to the maximum extent permitted by
law, presentment, demand, protest, notice of acceptance, notice of Obligations
incurred, notice of default or nonpayment, notice of dishonor and all other
notices of any kind, all defenses which may be available by virtue of any
valuation, stay, moratorium law or other similar law now or hereafter in effect,
any right to require the marshalling of assets of the Company, and all
suretyship defenses generally. Without limiting the generality of the foregoing,
the Guarantor agrees to the provisions of any instrument evidencing, securing or
otherwise executed in connection with any Obligation and agrees, to the maximum
extent permitted by law, that the obligations of the Guarantor hereunder shall
not be released or discharged, in whole or in part, or otherwise affected by (i)
the failure of any Bank or the Administrative Agent to assert any claim or
demand or to enforce any right or remedy against the Company; (ii) any
extensions or renewals of any Obligation; (iii) any rescissions, waivers,
amendments or modifications of any of the terms or provisions of any agreement
or instrument evidencing, securing or otherwise executed in connection with any
Obligation; (iv) the substitution or release of any entity primarily or
secondarily liable for any Obligation; (v) the adequacy of any rights any Bank
or the Administrative Agent may have against any collateral or other means of
obtaining repayment of the Obligations; (vi) the impairment of any collateral
securing the Obligations, including without limitation the failure to perfect or
preserve any rights any Bank or the Administrative Agent might have in such
collateral or the substitution, exchange, surrender, release, loss or
destruction of any such collateral; or (vii) to the fullest extent permitted by
applicable law, any other act or omission which might in any manner or to any
extent vary the risk of the Guarantor or otherwise operate as a release or
discharge of the Guarantor, all of which may be done without notice to the
Guarantor.

     5.   UNENFORCEABILITY OF OBLIGATIONS AGAINST COMPANY. If for any reason the
Company has no legal existence or is under no legal obligation to discharge any
of the Obligations undertaken or purported to be undertaken by it or on its
behalf, of if any of the Obligations have become irrecoverable from the Company
by operation of law or for any other reason, this Guaranty shall nevertheless be
binding on the Guarantor to the same extent as if the Guarantor at all times had
been the principal obligor on all such Obligations. In the event that
acceleration of the time for payment of the Obligations is stayed upon the
insolvency, bankruptcy or reorganization of the Company, or for any other
reason, all such amounts otherwise subject to acceleration under the terms of
any agreement or instrument evidencing, securing or otherwise executed in
connection with any Obligation shall be immediately due and payable by the
Guarantor.

     6.   WAIVER OF SUBROGATION; SUBORDINATION. Notwithstanding any other
provision of this Guaranty, until such time as all of the Obligations shall have
been paid and performed in full and the Credit Agreement and all Commitments
thereunder shall have terminated pursuant to the terms thereof, the Guarantor
hereby waives all rights of subrogation against the Company arising as a result
of payment by the Guarantor hereunder and will not prove any claim in
competition with any Bank in respect of any payment hereunder in bankruptcy or
insolvency

                                      H-2
<PAGE>

proceedings of any nature. The Guarantor hereby acknowledges that the waiver
contained in the preceding sentence (the "Subrogation Waiver") is given as an
inducement to the Banks to consummate the transactions contemplated by the
Credit Agreement and any other agreement referred to therein and, in
consideration of the willingness of the Banks to consummate said transactions,
the Guarantor agrees that it shall not in any way amend or modify the
Subrogation Waiver without the prior written consent of the Banks. The Guarantor
further acknowledges that the Subrogation Waiver is made for the benefit of any
and all creditors of the Company, whether existing on the date hereof or
thereafter arising, whether the claim of any such creditor against the Company
is direct or indirect, joint or several, absolute or contingent, matured or
unmatured, liquidated or unliquidated, secured or unsecured, arising by
contract, operation of law or otherwise. The Subrogation Waiver and the
provisions of this section shall survive the expiration or termination of the
Credit Agreement and all Commitments thereunder, this Guaranty and the other
Loan Documents. Until such time as all of the Obligations shall have been paid
and performed in full and the Credit Agreement and all Commitments thereunder
shall have been terminated pursuant to the terms thereof, the Guarantor will not
claim any set-off or counterclaim against the Company in respect of any
liability of the Guarantor to the Company; the Guarantor will not claim any set-
off or counterclaim (other than any compulsory counterclaim) against any Bank in
any proceeding or action to enforce this Guaranty; and the Guarantor waives any
benefit of and any right to participate in any collateral which may be held by
the Administrative Agent or any Bank. The payment of any amounts due with
respect to any indebtedness of the Company now or hereafter held by the
Guarantor is hereby subordinated to the prior payment in full of the
Obligations. The Guarantor agrees that after the occurrence of any Event of
Default in the payment or performance of the Obligations, the Guarantor will not
demand, sue for or otherwise attempt to collect any such indebtedness of the
Company to the Guarantor. If, notwithstanding the foregoing sentence, the
Guarantor shall collect, enforce or receive any amounts in respect of such
indebtedness, such amount shall be collected, enforced and received by the
Guarantor as trustee for the Banks and be paid over to the Administrative Agent
on account of the Obligations without affecting in any manner the liability of
the Guarantor under the other provisions of this Guaranty.

     7.   SET-OFF. The Administrative Agent and each of the Banks is hereby
authorized at any time and from time to time, without notice to the Guarantor
(any such notice being expressly waived by the Guarantor) and to the fullest
extent permitted by law, to set-off and apply such deposits and other sums
against the obligations of the Guarantor under this Guaranty.

     8.   REPRESENTATIONS, WARRANTIES AND COVENANTS. The Guarantor hereby
represents, warrants, and covenants to and with the Banks that:

          8.1. (a)  Corporate Status.  The Guarantor is a corporation duly
                    ----------------
     formed, validly existing and in good standing under the laws of the State
     of Delaware and has the power and authority to own its property, conduct
     its business as now being conducted and to make and perform this Guaranty
     and the transactions contemplated hereby, and is duly qualified to do
     business and in good standing as a foreign corporation in each jurisdiction
     where the nature and extent of the business conducted by it, or property
     owned by it, and

                                      H-3
<PAGE>

     applicable law required such qualification, except where the failure to so
     qualify would not have a material adverse effect on the Guarantor and its
     Subsidiaries, taken as a whole.

               (b)  Authorization.  The execution, delivery and performance of
                    -------------
     this Guaranty by the Guarantor have been duly authorized by all necessary
     corporate action and will not violate any provision of law or any order of
     any court or governmental agency or the charter, or other incorporation
     papers or bylaws (or the equivalent thereof) of the Guarantor or conflict
     with, or result in a breach of, or constitute (with or without notice or
     lapse of time or both) a default under, or result in the creation of any
     security interest, lien, charge or encumbrance upon any property or assets
     of the Guarantor pursuant to any agreement, indenture or other instrument
     to which it is a party or by which it may be bound which would have a
     material adverse effect upon the financial condition or operations of the
     Guarantor and its Subsidiaries, taken as a whole.

               (c)  Litigation.  Except as disclosed to the Banks in writing
                    ----------
     prior to the execution hereof, no action, suit, investigation or proceeding
     is pending or known to be threatened against or affecting the Guarantor
     which, if adversely determined, would have a material adverse effect upon
     the financial condition or operations of the Guarantor and its
     Subsidiaries, taken as a whole.

               (d)  Absence of Default.  The Guarantor is not in default under
                    ------------------
     any provision of its charter, or other incorporation papers, bylaws (or the
     equivalent thereof) or stock provisions or any amendment of any thereof, or
     any provision of law, or of any agreement, note, indenture or other
     instrument to which it is a party or by which it or any of its property is
     bound, or of any order of any court or public body or authority by which it
     or any of its property is bound, which would have a material adverse effect
     upon the financial condition or operations of the Guarantor and its
     Subsidiaries, taken as a whole.

               (e)  No Consents Required.  No license, consent or approval of or
                    --------------------
     filing with any governmental body or other regulatory authority is required
     for the making and performance of this Guaranty by the Guarantor or any
     instrument or transaction contemplated herein.  The Guarantor holds all
     certificates and authorizations of all governmental agencies and
     authorities required by law to enable it to engage in the business
     currently transacted by it, except where the failure to obtain such
     certificates and authorizations would not have a material adverse effect
     upon the financial condition or operations of the Guarantor and its
     Subsidiaries, taken as a whole.

               (f)  Enforceability.  This Guaranty has been duly executed and
                    --------------
     delivered by the Guarantor and is the valid and legally binding obligation
     of the Guarantor, enforceable in accordance with its terms, except as
     limited by bankruptcy, insolvency, reorganization, moratorium or similar
     laws relating to or affecting generally the enforcement of creditors'
     rights.

                                      H-4
<PAGE>

               (g)  Survival of Representations and Warranties.  All
                    ------------------------------------------
     representations and warranties of the Guarantor made herein shall survive
     until payment in full of all of the Obligations.

          8.2  Certain Negative Covenants.  The Guarantor covenants and agrees
               --------------------------
     that, until all of the Obligations have been paid and satisfied in full,
     the Guarantor shall not create or suffer to exist any mortgage, pledge,
     deed of trust or security interest on the capital stock (or any
     indebtedness convertible into capital stock) of any of its Subsidiaries.

     9.   TERMINATION; REINSTATEMENT. The Obligations of the Guarantor under
this Guaranty shall remain in full force and effect until all of the Obligations
have been indefeasibly satisfied. This Guaranty shall continue to be effective
or be reinstated if at any time any payment made or value received with respect
to an Obligation is rescinded or must otherwise be returned by any Bank or the
Administrative Agent upon the insolvency, bankruptcy or reorganization of the
Company, or otherwise, all as though such payment had not been made or value
received.

     10.  SUCCESSORS AND ASSIGNS. The obligations represented by this Guaranty
may not be assigned or delegated by the Guarantor without the prior written
consent of the Banks. This Guaranty shall be binding upon the Guarantor, its
permitted successors and assigns, and shall inure to the benefit of and be
enforceable by each of the Banks and their respective successors, transferees
and assigns. Without limiting the generality of the foregoing sentence, each
Bank may assign or otherwise transfer this Guaranty and/or any agreement or any
note held by it evidencing, securing or otherwise executed in connection with
the Obligations, or sell participations in any interest therein, to any other
person or entity and such other person or entity shall thereupon become vested
to the extent set forth in the agreement evidencing such assignment, transfer or
participation, with all the rights in respect thereof granted to such Bank
herein.

     11.  AMENDMENTS AND WAIVERS. No amendment or waiver of any provision of
this Guaranty nor consent to any departure by the Guarantor therefrom shall be
effective unless made in writing and the same shall be signed by the Banks. No
failure on the part of any Bank to exercise, and no delay in exercising, any
right hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right hereunder preclude any other or further exercise
thereof or the exercise of any other rights.

     12.  NOTICES. All notices and other communications called for hereunder
shall be made in accordance with Section 20 of the Credit Agreement (and shall
                                 ----------
be deemed to be effective at the times provided therein), addressed as follows:
if to the Guarantor, at the address set forth beneath the appropriate signature
line hereto, and if to the Banks, at the respective addresses set forth for the
Banks in the Credit Agreement, or at such other address as any party may
designate in writing in accordance with the provisions hereof.
