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
Day during the period from the Closing Date to the Termination Date, in an

Share of the Commitment; provided, that, after giving effect to any Borrowing of
Revolving Loans, the aggregate outstanding amount of the Revolving Loans plus

Share of the Commitment, and subject to the other terms and conditions hereof,
the Company may borrow under this subsection 2.1(a), prepay under Section 2.6
and reborrow under this subsection 2.1(a).

     (b) Swing Line Loans.
         ----------------

         (i) The Swing Line.  Subject to the terms and conditions set forth
             --------------
herein, the Swing Line Lender agrees to make loans (each such loan, a "Swing
Line Loan") to the Company from time to time on any Business Day during the
period from the Closing Date to the Termination Date in an aggregate amount not
to exceed at any time outstanding the amount of the Swing Line Sublimit,
notwithstanding the fact that such Swing Line Loans, when aggregated with the

as a Bank, may exceed its Pro Rata Share of the Commitment; provided, that after
giving effect to any Swing Line Loan, (A) the aggregate outstanding amount of
all Loans shall not exceed the Commitment, and (B) the aggregate outstanding
amount of the Loans of any Bank, plus such Bank's Pro Rata Share of the
                                 ----
outstanding amount of all Swing Line Loans shall not exceed such Bank's Pro Rata
Share of the Commitment, and provided, further, that the Swing Line Lender shall

Within the foregoing limits, and subject to the other terms and conditions
hereof, the Company may borrow under this subsection 2.1(b)(i), prepay under
Section 2.6, and reborrow under this subsection 2.1(b)(i);  provided, that the
Swing Line Lender may terminate or suspend the Swing Line at any time in its
sole discretion upon notice to the Company. Each Swing Line Loan shall be a Base
Rate Loan.  Immediately upon the making of a Swing Line Loan, each Bank shall be
deemed to, and hereby irrevocably and unconditionally agrees to, purchase from
the Swing Line Lender a risk

                                       16

participation in such Swing Line Loan in an amount equal to the product of such

          (ii)   Borrowing Procedures.  Unless the Swing Line Lender has
                 --------------------
notified the Company that the Swing Line has been terminated or suspended as
provided in subsection 2.1(b)(i), each Swing Line Borrowing shall be made upon
the Company's irrevocable notice to the Swing Line Lender and the Administrative
Agent, which may be given by telephone. Each such notice must be received by the
Swing Line Lender and the Administrative Agent not later than 12:00 noon (Dallas
time), on the requested Borrowing Date, and shall specify (A) the amount to be
borrowed, which shall be in a minimum amount of $500,000 or any multiple of
$100,000 in excess thereof, and (B) the requested Borrowing Date, which shall be
a Business Day. Each such telephonic notice must be confirmed promptly by
delivery to the Swing Line Lender and the Administrative Agent of a written
Swing Line Loan Notice, appropriately completed and signed by a responsible
officer of the Company. Promptly after receipt by the Swing Line Lender of any
telephonic Swing Line Loan Notice, the Swing Line Lender will confirm with the
Administrative Agent (by telephone or in writing) that the Administrative Agent
has also received such Swing Line Loan Notice and, if not, the Swing Line Lender
will notify the Administrative Agent (by telephone or in writing) of the
contents thereof. Unless the Swing Line Lender has received notice (by telephone
or in writing) from the Administrative Agent (including at the request of any
Bank) prior to 1:00 p.m. (Dallas time), on the date of the proposed Swing Line
Borrowing (x) directing the Swing Line Lender not to make such Swing Line Loan
as a result of the limitations set forth in the first proviso to the first
sentence of subsection 2.1(b)(i), or (y) that one or more of the applicable
conditions specified in Section 4 is not then satisfied, then, subject to the
terms and conditions hereof, the Swing Line Lender will, not later than 2:00
p.m. (Dallas time), on the Borrowing Date specified in such Swing Line Loan
Notice, make the amount of its Swing Line Loan available to the Company in

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

                 (A) The Swing Line Lender at any time in its sole and absolute
discretion may request, on behalf of the Company (which hereby irrevocably
requests the Swing Line Lender to act on its behalf), that each Bank make a Base
Rate Loan in an amount equal to such Bank's Pro Rata Share of the amount of
Swing Line Loans then outstanding.  Such request shall be made in accordance
with the requirements of  Section 2.3, without regard to the minimum and
multiples specified therein for the principal amount of Base Rate Loans, but
subject to the unutilized portion of the Commitment and the conditions set forth
in Section 4.2.  The Swing Line Lender shall furnish the Company with a copy of
the applicable Notice of Borrowing promptly after delivering such notice to the
Administrative Agent.  Each Bank shall make an amount equal to its Pro Rata
Share of the amount specified in such Notice of Borrowing, available to the
Administrative Agent in immediately available funds for the account of the Swing
Line Lender at the Administrative Agent's Office not later than 12:00 noon
(Dallas time), on the day specified in such Notice of Borrowing, whereupon,

The Administrative Agent shall remit the funds so received to the Swing Line
Lender.

                                       17
<PAGE>

               (B) If for any reason any Borrowing cannot be requested in
accordance with subsection 2.1(b)(iii)(A) or any Swing Line Loan cannot be
refinanced by such a Borrowing, the Notice of Borrowing submitted by the Swing
Line Lender shall be deemed to be a request by the Swing Line Lender that each
of the Banks fund its participation in the relevant Swing Line Loan and each
Bank's payment to the Administrative Agent for the account of the Swing Line
Lender pursuant to subsection 2.1(b)(iii)(A) shall be deemed payment in respect
of such participation.

               (C) If any Bank fails to make available to the Administrative
Agent for the account of the Swing Line Lender any amount required to be paid by
such Bank pursuant to the foregoing provisions of this subsection 2.1(b)(iii) by
the time specified in subsection 2.1(b)(iii)(A), the Swing Line Lender shall be
entitled to recover from such Bank (acting through the Administrative Agent), on
demand, such amount with interest thereon for the period from the date such
payment is required to the date on which such payment is immediately available
to the Swing Line Lender at a rate per annum equal to the Federal Funds Rate
from time to time in effect. A certificate of the Swing Line Lender submitted to
any Bank (through the Administrative Agent) with respect to any amounts owing
under this clause (C) shall be conclusive absent manifest error.

               (D) Each Bank's obligation to make Loans or to purchase and fund
participations in Swing Line Loans pursuant to this subsection 2.1(b)(iii) shall
be absolute and unconditional and shall not be affected by any circumstance,
including (x) any set-off, counterclaim, recoupment, defense or other right
which such Bank may have against the Swing Line Lender, the Company or any other
Person for any reason whatsoever, (y) the occurrence or continuance of a Default
or Event of Default, or (z) any other occurrence, event or condition, whether or
not similar to any of the foregoing. Any such purchase of participations shall
not relieve or otherwise impair the obligation of the Company to repay Swing
Line Loans, together with interest as provided herein.

          (iv) Repayment of Participations.
               ---------------------------

               (A) At any time after any Bank has purchased and funded a
participation in a Swing Line Loan, if the Swing Line Lender receives any
payment on account of such Swing Line Loan, the Swing Line Lender will
distribute to such Bank its Pro Rata Share of such payment (appropriately
adjusted, in the case of interest payments, to reflect the period of time during
which such Bank's participation was outstanding and funded) in the same funds as
those received by the Swing Line Lender.

               (B) If any payment received by the Swing Line Lender in respect
of principal or interest on any Swing Line Loan is required to be returned by
the Swing Line Lender, each Bank shall pay to the Swing Line Lender its Pro Rata
Share thereof on demand of the Administrative Agent, plus interest thereon from
the date of such demand to the date such amount is returned, at a rate per annum
equal to the Federal Funds Rate. The Administrative Agent will make such demand
upon the request of the Swing Line Lender.

                                       18
<PAGE>

          (v)  Interest for Account of Swing Line Lender.  The Swing Line Lender
               -----------------------------------------
shall be responsible for invoicing the Company for interest on the Swing Line
Loans.  Until each Bank funds its Base Rate Loan or participation pursuant to
this subsection 2.1(b) to refinance such Bank's Pro Rata Share of any Swing Line
Loan, interest in respect of such Pro Rata Share shall be solely for the account
of the Swing Line Lender.

          (vi) Payments Directly to Swing Line Lender.  The Company shall make
               --------------------------------------
all payments of principal and interest in respect of the Swing Line Loans
directly to the Swing Line Lender.

     2.2  Notes.  The Revolving Loans made by each Bank shall be evidenced by
          -----
one or more Notes and the Swing Line Loans made by the Swing Line Lender shall
be evidenced by the Swing Line Note.  Each Bank shall record in its records or,
at its option, endorse on the schedules annexed to its Note(s), the date, amount
and maturity of each Loan made by it and the amount of each payment of principal
made by the Company with respect thereto.  Each Bank is irrevocably authorized
by the Company to endorse its Note(s) and each Bank's record shall be rebuttable
presumptive evidence of the principal amount owing and unpaid on such Note(s);
provided, that the failure of a Bank to make, or an error in making, a notation
thereon with respect to any Loan shall not limit or otherwise affect the
obligations of the Company hereunder or under any such Note to such Bank.

     2.3  Procedure for Borrowing.
          -----------------------

     (a)  Each Borrowing (other than a Swing Line Borrowing), including any

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.

     (e)  Unless the Majority Banks otherwise agree, during the existence of a
Default or Event of Default, the Company may not elect to have a Loan converted
into or continued as a Eurodollar Loan.

     (f)  After giving effect to any conversion or continuation of Loans, there
may not be more than ten (10) different Interest Periods in effect.

     2.5  Voluntary Termination or Reduction of Commitment.  The Company may,
          ------------------------------------------------
upon not less than five Business Days' prior notice to the Administrative Agent
(which shall promptly notify each Bank thereof), terminate the Commitment, or
permanently reduce the Commitment by an aggregate minimum amount of $5,000,000
or any multiple of $1,000,000 in excess thereof; unless, after giving effect
thereto and to any prepayments of Revolving Loans and Swing Line Loans made on
the effective date thereof, the then-outstanding principal amount of the
Revolving Loans and Swing Line Loans would exceed the amount of the Commitment
then in effect.  Once reduced in accordance with this Section 2.5, the
Commitment may not be increased.  Any reduction of 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 reduction or
termination of the Commitment shall be paid on such date.

     2.6  Prepayments.
          -----------

     (a)  Optional Prepayments.
          --------------------

          (i)  Subject to Section 3, the Company may, at any time or from time
to time, upon not less than (x) in the case of Base Rate Loans, one Business
Day's irrevocable notice to the Administrative Agent, and (y) in the case of
Eurodollar Loans, three Business Days' irrevocable notice to the Administrative
Agent (which shall in each case promptly notify each Bank thereof), ratably
prepay Loans in whole or in part, in minimum amounts of $1,000,000 or any
multiple of $100,000 in excess thereof. Such notice of prepayment shall specify
the date and amount of such prepayment, and the Type(s) of Loans to be prepaid.
The Administrative Agent will promptly notify each Bank of its receipt of any
such notice, and of such Bank's Pro Rata

                                       21
<PAGE>

Share of such prepayment. If such notice is given by the Company, the Company
shall make such prepayment and the payment amount specified in such notice shall
be due and payable on the date specified therein, together, if such prepayment
is a prepayment of Eurodollar Loans, with accrued interest to each such date on
the amount prepaid and any amounts required pursuant to Section 3.

          (ii) Subject to Section 3, the Company may, at any time or from time
to time, upon irrevocable notice received by the Swing Line Lender not later
than 12:00 noon (Dallas time) on the date of prepayment (with a copy of such
notice to the Administrative Agent), prepay Swing Line Loans in whole or in
part, in minimum amounts of $500,000 or any multiple of $100,000 in excess
thereof. Such notice of prepayment shall specify the date and amount of such
prepayment. If such notice is given by the Company, the Company shall make such
prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein, together with accrued interest to such
date on the amount prepaid and any amount required pursuant to Section 3.

     (b)  Mandatory Prepayment Upon Change of Control. No later than the date of
          -------------------------------------------
the occurrence of any Change of Control, the Company shall give written notice
thereof to the Administrative Agent accompanied by a certificate of the
president, the chief financial officer or the general counsel of the Company
specifying the nature of such Change of Control and the date on which such
Change of Control occurred. Such notice shall (a) contain the written,
irrevocable offer of the Company to prepay in full all Obligations of the
Company (including, without limitation, all Obligations under Section 3 hereof)
on a date (the "Change of Control Prepayment Date") specified in such notice
(which date shall in no event be later than the date which is five (5) Business
Days after the date such Change of Control shall have occurred), (b) state that,
unless the Company receives written notice to the contrary from the
Administrative Agent at the direction of the Majority Banks not later than one
Business Day prior to the Change of Control Prepayment Date, the Company's offer
to prepay under this Section 2.6(b) shall be deemed to have been accepted by the
Administrative Agent at the direction of the Majority Banks, (c) state the
outstanding principal amount under each of the Notes as of the date of such
notice and (d) contain such additional information as the Administrative Agent
or any Bank shall reasonably request. If the Company does not receive written
notice from the Administrative Agent on or before the Business Day preceding the
Change of Control Prepayment Date, of the election of the Administrative Agent
at the direction of the Majority Banks not to accept the offer of the Company to
prepay as described above, all Obligations shall become immediately due and
payable by the Company on the Change of Control Prepayment Date and the
Commitment shall be terminated on such date.

     2.7  Repayment.
          ---------

     (a)  The Revolving Credit.  The Company shall repay to the Banks on the
          --------------------
Termination Date the aggregate principal amount of Revolving Loans outstanding
on such date, plus all accrued and unpaid interest thereon.

                                       22
<PAGE>

     (b)  Swing Line Loans.  The Company shall repay to the Swing Line Lender
          ----------------
the aggregate principal amount of Swing Line Loans, plus all accrued and unpaid
interest thereon,  on the earlier to occur of (i) demand by the Swing Line
Lender and (ii) the Termination Date.

     2.8  Interest.
          --------

     (a)  Each Loan shall bear interest on the outstanding principal amount
thereof from the applicable Borrowing Date at a rate per annum equal to (i) the
Adjusted Eurodollar Rate, in the case of Eurodollar Loans, (ii) the Adjusted
Base Rate, in the case of Base Rate Loans and (iii) the Swing Line Rate, in the
case of Swing Line Loans, as the case may be (and subject to the Company's right
to convert to other Types of Loans under Section 2.4).

     (b)  Interest on each Loan shall be paid in arrears on each Interest
Payment Date. Interest shall also be paid on the date of any prepayment of
Eurodollar Loans or Swing Line Loans under Section 2.6 for the portion of the
Eurodollar Loans or Swing Line Loans so prepaid and upon payment (including
prepayment) in full of the Loans and also, during the existence of any Event of
Default, interest shall be paid on demand of the Administrative Agent at the
request or with the consent of the Majority Banks.

     (c)  Notwithstanding subsection (a) of this Section 2.8, if any amount of
principal of or interest on any Loan, or any other amount payable hereunder or
under any other Loan Document is not paid in full when due (whether at stated
maturity, by acceleration, demand or otherwise), the Company agrees to pay
interest on such unpaid principal or other amount, from the date such amount
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
demand, at a fluctuating rate per annum equal to the interest rate otherwise
applicable hereunder plus two percent (2%).

     (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.

     2.9  Fees.
          ----

     (a)  Arrangement, Agency Fees.  The Company shall pay all of the fees
          ------------------------
payable under the Fee Letter as and when such fees become due and payable
pursuant to the terms thereof.

     (b)  Utilization Fee and Non-Use Fee.  The Company shall pay to the
          -------------------------------
Administrative Agent for the account of each Bank and in accordance with each
Bank's Pro Rata Share:

                                       23
<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 (including Swing Line 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 364 Day Loans exceeds 33 1/3% of the sum of the Commitment
     and the 364 Day Commitment in effect for such calendar quarter; and

          (ii) a  fee (the "Non-Use Fee") for the period from the Closing Date
                            -----------
     to the Termination 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 other
     than the Swing Line 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 Termination Date occurs on any day other than the last day
of a calendar quarter, on or before the fifth (5/th/) Business Day following the
Termination Date.

     2.10 Computation of Interest.
          -----------------------

     (a)  All computations of interest for Base Rate Loans (including Swing Line
Loans) when the Base Rate is 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.

                                       24
<PAGE>

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

     (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

                                       25
<PAGE>

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 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

                                       26
<PAGE>

     to additional sums payable under this Section) such Bank or the
     Administrative Agent, as 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

                                       27
<PAGE>

day of the Interest Period thereof, if such Bank may lawfully continue to
maintain such Eurodollar 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

                                       28
<PAGE>

which adjustments are to be made under this subsection 3.3(b) has been prepaid
in full, as the 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

                                       29
<PAGE>

Eurodollar Loans, or of a claim by such Bank for compensation under Section 3.3,
the Company may: (i) request one or more of the other Banks to acquire and
assume all or part of such Affected Bank's Loans (including, without limitation,
any continuing obligation of the Affected Bank to purchase participations in
Swing Line Loans hereunder) 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.

4.   CONDITIONS PRECEDENT.
     --------------------

     4.1  Conditions of Initial Loans. The obligation of each Bank to make its
          ---------------------------
initial Loan hereunder is subject to the condition precedent that the
Administrative Agent has received on or before the Closing Date all of the
following, in form and substance satisfactory to the Administrative Agent and
each Bank, and in sufficient copies for each Bank:

be not continuing; but no such waiver shall extend to or affect any subsequent

 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,

      (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, or the participations in
Swing Line Loans held 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 or such subparticipations in the participations in Swing Line
Loans held by them, as the case may be, as shall be necessary to cause such
purchasing Bank to share the excess payment in respect of such

                                       45
<PAGE>

Loans or such participations, as the case may be, 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
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 Section 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

                                       46
<PAGE>

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
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.

                                       47

      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 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

                                       48
<PAGE>

hereunder and without notice to or consent of the other Agents or the Banks. 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 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

                                       49
<PAGE>

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 (including for purposes of this clause (a),
participations in Swing Line 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,
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
                                      -------------------------
ny Note or Notes subject to such assignment, and (iii) the assignor Bank or
Assignee has paid to the

                                       50
<PAGE>

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.
                                 --- -----

     (c)  Notwithstanding anything to the contrary contained herein, if at any
time Bank of America assigns all of its Pro Rata Share of the Commitment and
Loans pursuant to subsection 12.1(a), Bank of America may upon three Business
Days' notice to the Company, terminate the Swing Line. In the event of any such
termination of the Swing Line, the Company shall be entitled to appoint from
among the Banks a successor Swing Line Lender hereunder; provided, that no
failure by the Company to appoint any such successor shall affect the
termination of the Swing Line. If Bank of America terminates the Swing Line, it
shall retain all the rights of the Swing Line Lender provided for hereunder with
respect to Swing Line Loans made by it and outstanding as of the effective date
of such termination, including the right to require the Banks to make Base Rate
Loans or fund participations in outstanding Swing Line Loans pursuant to
subsection 2.1(b)(iii).

     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 (including such Bank's
 -----------
participations in Swing Line 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
                 -----

                                       51
<PAGE>

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 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.

affect the right of the Administrative Agent or any Bank to bring any action or
proceeding against the Company or its property in the courts of any other
jurisdictions.

                                       52

all of the parties hereto and the conditions precedent set forth in Section 4.1
shall have been satisfied, and shall be binding upon and inure to the benefit of
the Company, the Banks and the Administrative Agent and their respective
successors and assigns, except that the Company shall not have the right to
assign its rights hereunder or any interest herein without the prior written
consent of the Banks and any attempted assignment without such consent shall be
void.

 15. FEES AND EXPENSES; INDEMNITY.

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

any other Loan Document during the existence of an Event of Default or after
acceleration of the Loans (including in connection with any "workout" or
restructuring regarding the Loans, and including in any insolvency proceeding or
appellate proceeding).

     15.2     Company Indemnification.  Whether or not the transactions
              -----------------------
contemplated hereby are consummated, the Company shall indemnify and hold the

                             ------------------
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, charges, expenses and disbursements (including
reasonable Attorney Costs) of any kind or nature whatsoever which may at any
time (including at any time following repayment of the Loans and the

any of the foregoing, including with respect to any investigation, litigation or
proceeding (including any insolvency proceeding or appellate proceeding) related
to or arising out of this Agreement or the Loans or the use of the proceeds
thereof, whether or not any Indemnified Person is a party thereto (all the
foregoing, collectively, the "Indemnified Liabilities"); provided, that the
                              -----------------------
Company shall have no obligation hereunder to any Indemnified Person with
respect to Indemnified Liabilities to the extent resulting from the gross
negligence or willful misconduct of such Indemnified Person. The agreements in
this Section 15.2 shall survive payment of all other Obligations and termination
of this Agreement.

 16. REMEDIES CUMULATIVE.
     -------------------

     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,
and no such counterclaim (other than any compulsory counterclaims) or offset
shall be asserted by the Company in any action, suit or proceeding instituted by
the Administrative Agent or any Bank for payment or performance of the Company's
Obligations.

 17. FURTHER ASSURANCES.
     ------------------

     At any time and from time to time, upon the request of any Bank or the
Administrative Agent, the Company shall execute, deliver and acknowledge or
cause to be executed, delivered and acknowledged, such further documents and do
such other acts and things as such Bank or the Administrative Agent may
reasonably request in order to fully effect the purposes of this Agreement, the
other Loan Documents and any other documents delivered pursuant hereto or in
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 investigation

                                       54
<PAGE>

heretofore or hereafter made by the Administrative Agent or the Banks, and shall
survive the making by the Banks of the Loans as herein contemplated and shall
continue in full force and effect so long as any 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 the transactions
contemplated hereby shall constitute representations and warranties by the
Company hereunder.

 19. SEVERABILITY.
     ------------

     The provisions of this Agreement are severable, and if any clause or
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, the Swing
Line Lender or the Administrative Agent, to such other address as shall be
designated by such party in a written notice to the other parties, and as
directed to any other party, at such other address as shall be designated by
such party in a written notice to the Company, the Swing Line Lender and the
Administrative Agent.

     (b) All such notices, requests and communications shall, when transmitted

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,
upon delivery, or if delivered by electronic mail (which form of delivery is
subject to the provisions of subsection (e) below), when delivered; except that
notices pursuant to Section 2 or Section 11 shall not be effective until
actually received by the Administrative Agent or the Swing Line Lender, as
appropriate.

     (c) Any agreement of the Administrative Agent, the Swing Line Lender 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, the Swing Line Lender 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, the Swing Line Lender 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, the Swing Line Lender
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, the Swing Line Lender
and the Banks to receive written confirmation of any telephonic or facsimile
notice or the receipt by the Administrative Agent, the Swing Line Lender and the
Banks of a confirmation which is at variance

                                       55
<PAGE>

with the terms understood by the Administrative Agent, the Swing Line Lender 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, the Swing Line Lender and the
Banks.  The Administrative Agent or the Swing Line Lender 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

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

     No amendment or waiver of any provision of this Agreement or any other Loan

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);

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

     (e) amend this Section 24, or Section 10, or any provision herein providing

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

and, provided, further, that (i) no amendment, waiver or consent shall, unless

amendment, waiver or consent shall, unless in writing and signed by the Swing

be, affect the rights or duties of the Swing Line Lender under this Agreement or
any other Loan Document, and (iii) 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 Termination 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

                                       57
<PAGE>

agreed to such increase and/or (b) 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 $165,000,000 without the
written consent of all Banks; and (iii) the Commitment under (and as defined in)
the 364 Day Agreement shall be increased in proportion to the increased
Commitment under this Agreement (provided that the 364 Day 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.

                          FIVE-YEAR 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 Five-Year 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 and Swing Line Lender, 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 marshaling 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 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

                                      H-2
<PAGE>

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 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

                                      H-3
<PAGE>

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.

               (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
               --------------------------

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

<PAGE>

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

     13.  GOVERNING LAW; CONSENT TO JURISDICTION.  This Guaranty shall be

the State of Illinois, without regard to the conflicts of law provisions
thereof.  The Guarantor agrees that any suit for the enforcement of this

sitting in Chicago, Illinois, and consents to the non-exclusive jurisdiction of
such court and to service of process in any such suit being made upon the
Guarantor by mail at the address of the Guarantor set forth beneath the
appropriate signature line hereto.  The Guarantor hereby waives any objection
that it may now or hereafter have to the venue of any such suit or any such
court or that such suit was brought in an inconvenient court.

     14.  WAIVER OF TRIAL BY JURY.  THE GUARANTOR HEREBY WAIVES ALL RIGHTS TO
TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR
RELATING TO THIS GUARANTY OR ANY OTHER AGREEMENT, INSTRUMENT OR OTHER DOCUMENT

Guarantor with respect to the matters set forth herein.  The rights and remedies
herein provided are cumulative and not exclusive of any remedies provided by law

     (b)  Favored Customer for FleetView Units.  During the Initial Term or any

Renewal Term, if Terion sells FleetView Units to a third party in the Territory
(other than a Trailer Rental/Leasing Company) at a price that is lower than the
price set forth on Schedule 1 (the "Lower Price"), XTRA shall receive the
                   ----------
benefit of the Lower Price on all subsequent purchases of the FleetView Units

          ------
Terion sells the FleetView Unit for a price that is less than the then current
average XTRA Net Book Value, then XTRA shall receive a per FleetView Unit rebate
for all FleetView Units previously purchased by XTRA that is equal to:

          (i)  if the sale of the FleetView Unit is made to a Trailer
Rental/Leasing Company in the Territory, the difference between the then current
average XTRA Net Book Value and the price paid by such Trailer Rental/Leasing
Company, plus an additional rebate of  ten percent (10%) of  the price paid by

the right to access the Communication Services for use with the FleetView Unit
in the Territory to Rental User's.  XTRA shall pay Terion's standard

                               ----------
price for a monthly rate plan that is available to Terion customers, XTRA shall
be charged the lower price for such available monthly rate plan .
Notwithstanding the foregoing, Terion may sell Communication Services at a price
that is lower than the price paid by XTRA in connection with XTRA's rights to
provide lease financing to a third party, provided that Terion shall make such
Communications Services pricing available to XTRA in connection with lease

FleetView Unit will be free from defects in material and workmanship under

FleetView Unit.  Any replacement will be new.  If such replacement is not
performed by Terion in a timely manner, XTRA shall have the option upon
reasonable notice to Terion to replace the defective Unit and invoice Terion for
the labor costs associated with such Unit replacements.  FleetView Units that
are replaced become the property of Terion.  Repaired or replaced FleetView
Units will be warranted as provided above for the balance of the original one
(1) year period.  Terion shall also pay reasonable labor charges for the
installation of any replacement batteries on FleetView Units due to normal use.

     (i)  Terion's Limited Software Warranty.  During the Initial Term and any
          ----------------------------------
Renewal Term, Terion warrants that the Software will operate in substantial
conformance with written performance-related materials provided by Terion to
XTRA under normal use and service. The sole obligation of Terion and the sole
remedy of XTRA under this warranty is for Terion to use commercially reasonable
efforts to either correct the defect or provide a suitable "bug fix" or "work
around" within thirty (30) days after notice from XTRA.  XTRA shall not be
responsible for any Communication Services charges if the Software does not
operate in substantial conformance with such written performance related
materials and such problem is not corrected by Terion within thirty (30) days
after receiving notice from XTRA. Corrected Software, will be warranted as

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

          (a)  Exercisability. The Holder's right to purchase the Warrant
               --------------
Shares shall be immediately exercisable.

          (b)  Manner of Exercise.  Except as otherwise provided herein, this
               ------------------
Warrant may be exercised in whole or in part on any business day (the "Exercise
Date") by presentation and surrender hereof to the Company at its principal
office at the following address: 420 N. Wickham Road, Melbourne, FL 32935, or at
the office of its stock transfer or warrant agent, if any, (or at such other
address as the Company may hereafter notify the Holder in writing) with the
Purchase Form annexed hereto duly executed and accompanied by proper payment of
the

                                      -28-
<PAGE>

Exercise Price in lawful money of the United States of America in the form of a
check (subject to collection) or wire transfer to an account designated by the
Company, for the number of Warrant Shares specified in the Purchase Form. If
this Warrant should be exercised in part only, the Company shall, upon surrender
of this Warrant, execute and deliver a new Warrant evidencing the rights of the
Holder thereof to purchase the balance of the Warrant Shares purchasable
hereunder, subject to the same terms and conditions as would be applicable under
this Warrant. Upon receipt by the Company of this Warrant and such Purchase
Form, together with proper payment of the Exercise Price, the Holder shall be
deemed to be the holder of record of the Warrant Shares, notwithstanding that
the stock transfer books of the Company shall then be closed or that the
certificates representing such Warrant Shares shall not then be actually
delivered to the Holder. The Holder shall pay any and all documentary stamp or
similar issue or transfer taxes payable in respect of the issue or delivery of
the Warrant Shares.

          (c)  HSR.  Notwithstanding anything to the contrary elsewhere herein,
               ---
the Holder acknowledges and agrees that its right to exercise this Warrant shall
be contingent upon, in each instance, the expiration of all waiting periods and
the receipt of any authorizations or consents that the Company, in its sole
discretion, may determine are required under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), or any other applicable
rule or regulation by which the Company is bound. The Holder shall provide the
Company not less than ten (10) business days' prior written notice, in each
instance, of its intention to exercise this Warrant, specifying the number of
Warrant Shares that the Holder intends to purchase and the aggregate purchase
price payable therefore.

     3.  Reservation of Shares.  The Company shall reserve at all times for
         ---------------------
issuance and delivery upon exercise or conversion of this Warrant all shares of
its Common Stock or other shares of Capital Stock of the Company from time to
time issuable upon exercise of this Warrant.  All such shares shall be duly
authorized and, when issued upon the exercise or conversion of this Warrant in
accordance with the terms hereof, including payment of the applicable Exercise
Price in full, shall be validly issued, fully paid and nonassessable, free and
clear of all liens, security interests, charges and other encumbrances or
restrictions ("Liens") on sale (other than (i) restrictions pursuant to
applicable federal and state securities laws, and (ii) any Liens created by any
action or inaction of the Holder of the Warrant Shares) and free and clear of
all preemptive rights.

     4.  Fractional Interest.  The Company will not issue a fractional share of
         -------------------
Common Stock or scrip upon any exercise or conversion of this Warrant.  Instead,
the Company will deliver its check for the current market value of the
fractional share.  The current market value of a fraction of a share is
determined as follows:  multiply the current market price of a full share by the
fraction of a share and round the result to the nearest cent.

     The current market value of a share of Common Stock for purposes of this
Section shall be determined as follows:

          (i)  If the Common Stock is listed on a national securities exchange
     or admitted to unlisted trading privileges on such exchange or listed for
     trading on The NASDAQ National Market, the current market value shall be
     the last reported sale price

                                      -29-
<PAGE>

     of the Common Stock on such exchange or Market on the last business day
     prior to the date of exercise or conversion of this Warrant or if no such
     sale is made on such day, the average closing bid and asked prices for such
     day on such exchange or Market; or

          (ii)      If the Common Stock is not so listed or admitted to unlisted
     trading privileges, the current market value shall be the mean of the last
     reported bid and asked prices reported by the National Quotation Bureau,
     Inc., on the last business day prior to the date of exercise or conversion;
     or

          (iii)     If the Common Stock is not so listed or admitted to unlisted
     trading privileges and bid and asked prices are not so reported, the
     current market value per share shall be an amount determined in such
     reasonable manner as may be prescribed in good faith by the Board of
     Directors of the Company.

     5.   Assignment or Transfer of Warrant.
          ---------------------------------

          (a)  Conditions.  The Holder shall not assign or otherwise transfer
               ----------
its interest in this Warrant, or any of the Warrant Shares, in whole or in part,
unless: (i) the Company shall have consented in writing to the proposed
transfer; (ii) the proposed transferee shall have agreed in writing, in form and
substance satisfactory to the Company, to be bound by the terms of this Warrant;
and (iii) the Holder shall have provided the Company with an opinion of counsel
in such form reasonably acceptable to the Company, that such transfer would not
be in violation of the Act or any applicable state securities or blue sky laws.

          (b)  Procedure.  Subject to the provisions of 5(a) above and Section
               ---------
8 below, upon surrender of this Warrant to the Company or at the office of its
stock transfer agent or warrant agent, with the Assignment Form annexed hereto
duly executed and funds sufficient to pay any transfer tax, the Company shall,
without charge, execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees named in such instrument of assignment and, if the
Holder's entire interest is not being assigned, in the name of the Holder, and
this Warrant shall promptly be canceled.

     6.   Adjustment of Exercise Price and Number of Shares.  The number and
          -------------------------------------------------
kind of securities purchasable upon the exercise of this Warrant and the
Exercise Price shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

          (a)  Reclassification, Consolidation or Merger.  In case of any
               -----------------------------------------
reclassification or change of outstanding securities issuable upon exercise or
conversion of this Warrant (other than a change in par value, or from par value
to no par value, or from no par value to par value or as a result of a
subdivision or combination) or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with another
corporation in which the Company is a continuing corporation and which does not
result in any reclassification or change, other than a change in par value, or
from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination of outstanding securities issuable upon
the exercise of this Warrant), the Company, or such successor or purchasing
corporation, as the case may be, shall, without payment of any additional
consideration therefore,

                                      -30-
<PAGE>

execute a new warrant providing that the Holder of the Warrant shall have the
right to exercise such new warrant (upon terms not less favorable to the Holder
than those then applicable to this Warrant) and to receive upon such exercise,
in lieu of each share of Common Stock theretofore issuable upon exercise or
conversion of this Warrant, the kind and amount of shares of stock, other
securities, money or property receivable upon such reclassification, change,
consolidation or merger by the Holder of one share of Common Stock issuable upon
exercise or conversion of this Warrant had the Warrants been exercised or
converted immediately prior to such reclassification, change, consolidation, or
merger. Such new warrant shall provide for adjustments, which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this
Section. The provisions of this subsection shall similarly apply to successive
reclassifications, changes, consolidations, or mergers.

          (b)  Subdivision or Combination of Shares.  If, at any time while
               ------------------------------------
this Warrant remains outstanding and unexpired, the Company shall subdivide or
combine its Capital Stock, the Exercise Price shall be proportionately reduced,
in case of subdivision of shares, as of the effective date of such subdivision,
or, if the Company shall take a record of holders of its Capital Stock for the
purpose of so subdividing, as of such record date, whichever is earlier, or
shall be proportionately increased, in the case of combination of shares, as of
the effective date of such combination, or, if the Company shall take a record
of holders of its Capital Stock for the purpose of so combining, as of such
record date, whichever is earlier.

          (c)  Stock Dividends and Distributions.  If the Company at any time
               ---------------------------------
while this Warrant is outstanding and unexpired shall pay a dividend in shares
of, or make other distribution of shares of, its Capital Stock, then the
Exercise Price shall be adjusted, as of the date the Company shall take a record
of the holders of its Capital Stock for the purpose of receiving such dividend
or other distribution (or if no such record is taken, as at the date of such
payment or other distribution), to that price determined by multiplying that
Exercise Price in effect immediately prior to such payment or other distribution
by a fraction (a) the numerator of which shall be the total number of shares of
Capital Stock outstanding immediately prior to such dividend or distribution,
and (b) the denominator of which shall be the total number of shares of Capital
Stock outstanding immediately after such dividend or distribution. The number of
shares of Capital Stock at any time outstanding shall not include any shares
thereof then directly or indirectly owned or held by or for the account of the
Company.

          (d)  Sale of Shares Below Conversion Price.
               -------------------------------------

               (i)  Adjustment.  Subject to the remaining provisions of this
                    ----------
paragraph (d), if the Company at any time while this Warrant is outstanding and
unexpired shall issue or sell Additional Shares of Common Stock, other than as a
dividend or distribution as provided in Section 6(c) above, and other than upon
a subdivision or combination as provided in Section 6(b) above, for a
consideration per share less than the Exercise, then and in each case the
Exercise Price shall be reduced, as of the opening of business on the date of
such issue or sale, to a price determined by multiplying the Exercise Price by a
fraction (A) the numerator of which shall be (x) the number of shares of Common
Stock outstanding immediately prior to such issue or sale, plus (y) the number
of shares of Common Stock that the aggregate consideration received by the
Company for the total number of Additional Shares of Common Stock so issued
would purchase

                                      -31-
<PAGE>

at such Exercise Price, and (B) the denominator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issue or sale plus
the number of such Additional Shares of Common Stock so issued.

               (ii)   Amount of Consideration. For the purpose of making any
                      -----------------------
adjustment in the Exercise Price or number of Warrant Shares purchasable
hereunder, the consideration received by the Company for any issue or sale of
securities shall:

                      (A)  to the extent it consists of cash, be computed at the
amount of cash received by the Company after deduction of any underwriting or
similar commissions, concessions or compensation paid or allowed by the Company
in connection with such issue or sale;

                      (B)  to the extent it consists of services or property
other than cash, be computed at the fair value of such services or property as
determined in good faith by the Board of Directors of the Company; and

                      (C)  if Additional Shares of Common Stock, Convertible
Securities (as hereinafter defined), or rights or options to purchase either
Additional Shares of Common Stock or Convertible Securities are issued or sold
together with other stock or securities or other assets of the Company for a
consideration that covers all assets sold by the Company, be computed as the
portion of the consideration so received that may be reasonably determined in
good faith by the Board of Directors of the Company to be allocable to such
Additional Shares of Common Stock, Convertible Securities or rights or options.

               (iii)  Issuance of Convertible Securities.  For the purpose of
                      ----------------------------------
the adjustment provided in subsection (i) of this Section 6(d), if the Company
at any time while this Warrant is outstanding and unexpired shall issue any
options, warrants or other rights for the purchase of, or stock or other
securities convertible into or exchangeable or redeemable for, Additional Shares
of Common Stock (such convertible stock or securities being hereinafter referred
to as "Convertible Securities"), then, in each case, if the Effective Price (as
defined in the next sentence) of such rights, options or Convertible Securities
shall be less than the Exercise Price, then and in each case the Company shall
be deemed to have issued at the time of the issuance of such rights or options
or Convertible Securities the maximum number of Additional Shares of Common
Stock issuable upon exercise or conversion thereof and to have received as
consideration for the issuance of such shares an amount equal to the total
amount of the consideration, if any, received by the Company for the issuance of
such rights or options or Convertible Securities, plus, in the case of such
options or rights, the minimum amounts of consideration, if any, payable to the
Company upon exercise or conversion of such options or rights. For purposes of
this paragraph, "Effective Price" shall mean the quotient determined by dividing
the total of all such consideration by such maximum number of Additional Shares
of Common Stock. No further adjustment of any Exercise Price adjusted upon the
issuance of such rights, options or Convertible Securities shall be made as a
result of the actual issuance of Additional Shares of Common Stock on the
exercise of any such rights or options or the conversion of any such Convertible
Securities.

                                      -32-
<PAGE>

     If any such rights or options or the conversion privilege represented by
any such Convertible Securities shall expire without having been exercised, the
respective Conversion Prices adjusted upon the issuance of such rights, options
or Convertible Securities shall be readjusted to the Conversion Prices that
would have been in effect had an adjustment been made on the basis that the only
Additional Shares of Common Stock so issued were the Additional Shares of Common
Stock, if any, actually issued or sold on the exercise of such rights or
options, or rights of conversion of such Convertible Securities, and such
Additional Shares of Common Stock, if any, were issued or sold for the
consideration actually received by the Company upon such exercise, plus the
consideration, if any, actually received by the Company for the granting of all
such rights and options, whether or not exercised, plus the consideration
received for issuing or selling the Convertible Securities actually converted
plus the consideration, if any, actually received by the Company on the
conversion of such Convertible Securities.

               (iv) Issuance of Rights or Options for the Purchase of
                    -------------------------------------------------
Convertible Securities. For the purpose of the adjustment provided for in
----------------------
subsection (i) of this Section 6(d), if the Company at any time while this
Warrant is outstanding and unexpired issue any rights or options for the
purchase of Convertible Securities, then in each such case, if the Effective
Price (as defined in the next sentence) thereof shall be less than the Exercise
Price, the Company shall be deemed to have issued at the time of the issuance of
such rights or options the maximum number of Additional Shares of Common Stock
issuable upon conversion of the total amount of Convertible Securities covered
by such rights or options and to have received as consideration for the issuance
of such Additional Shares of Common Stock an amount equal to the amount of
consideration, if any, received by the Company for the issuance of such rights
or options, plus the minimum amounts of consideration, if any, payable to the
Company upon the conversion of such Convertible Securities. For the purposes of
this paragraph, "Effective Price" shall mean the quotient determined by dividing
the total amount of such consideration by such maximum number of Additional
Shares of Common Stock. No further adjustment of any Exercise Price adjusted
upon the issuance of such rights or options shall be made as a result of the
actual issuance of the Convertible Securities upon the exercise of such rights
or options or upon the actual issuance of Additional Shares of Common Stock upon
the conversion of such Convertible Securities.

          The provisions of subsection (iii) above for the readjustment of the
Conversion Prices upon the expiration of rights or options or the rights of
conversion of Convertible Securities, shall apply mutatis mutandis (with the
necessary changes having been made) to the rights, options and Convertible
Securities referred to in this subsection (iv).

               (v)  Other Action Affecting Capital Stock.  In case after the
                    ------------------------------------
date hereof the Company shall take any action affecting the Capital Stock, other
than an action described in any of the foregoing provisions of this Section,
which in the opinion of the Company's Board of Directors would have a materially
adverse effect upon the rights of the Holder to purchase the Warrant Shares, the
Exercise Price shall be adjusted in such manner and at such time as the Board of
Directors may in good faith determine to be equitable in the circumstances.

                                      -33-
<PAGE>

          (e)  Notices of Record Date. In the event of (i) any taking by the
               ----------------------
Company of a record of the holders of any class or series of securities for the
purpos of determining the holders thereof who are entitled to receive any
dividend or other distribution or (ii) any reclassification or recapitalization
of the capital stock of the Company, any merger or consolidation of the Company,
or any transfer of all or substantially all the assets of the Company to any
other corporation, entity or person, or any voluntary or involuntary
dissolution, liquidation or winding up of the affairs of the Company, the
Company shall mail to the Holder at least 30 days prior to the record date
specified therein, a notice specifying (A) the date on which any such record is
to be taken for the purpose of such dividend or distribution, (B) the date on
which any such reorganization, reclassification, transfer, consolidation,
merger, dissolution, liquidation or winding up is expected to become effective,
and (C) the time, if any is to be fixed, as to when the holders of record of
Common Stock (or other securities) shall be entitled to exchange their shares of
Common Stock (or other securities) for securities or other property deliverable
upon such reorganization, reclassification, transfer, consolidation, merger,
dissolution, liquidation or winding up.

          (f)  Adjustment of Number of Shares. Upon each adjustment in the
               ------------------------------
Exercise Price pursuant to any provisions of this Section, the number of shares
of Common Stock purchasable hereunder shall be adjusted, to the nearest one
hundredth of a whole share, to the product obtained by multiplying such number
of shares purchasable immediately prior to such adjustment by a fraction, the
numerator of which shall be the Exercise Price immediately prior to such
adjustment and the denominator of which shall be the Exercise Price immediately
thereafter.

          (g)  Officer's Certificate. Whenever the Exercise Price shall be
               ---------------------
adjusted as required by the provisions of this Section, the Company shall
forthwith file in the custody of its secretary or an assistant secretary at its
principal office an officers' certificate showing the adjusted Exercise Price
determined as herein provided, setting forth in reasonable detail the facts
requiring such adjustment and the manner of computing such adjustment. Each such
officers' certificate shall be signed by the chairman, president or chief
financial officer of the Company and by the secretary or any assistant secretary
of the Company. A copy of each such officers' certificate shall be promptly
mailed, by certified mail, to the Holder and the original shall be made
available at all reasonable times for inspection by any other holder of a
Warrant executed and delivered pursuant to Section 5 hereof.

     7.   Rights of the Holder.  The Holder shall not, by virtue hereof, be
          --------------------
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those set forth in this Warrant. The
Holder shall be entitled to execute and enter into the Company's Seventh Amended
and Restated Registration Rights Agreement dated as of August 10, 2000, as
amended, providing for certain registration rights with respect to the Warrant
Shares, but not the Warrant and pursuant to which the Holder will agree to a 180
day lock-up with respect to the Warrant Shares.

     8.   Transfer to Comply with the Securities Act of 1933. No sale, transfer,
          --------------------------------------------------
assignment, hypothecation or other disposition of this Warrant or of the Warrant
Shares shall be made if such transfer, assignment or other disposition would
result in a violation of the Act, or
                                      -34-
<PAGE>

any state securities laws. Upon exercise of this Warrant, the Holder shall, if
requested by the Company, confirm in writing, in a form reasonably satisfactory
to the Company, that the shares of Common Stock so purchased are being acquired
solely for the Holder's own account, and not as a nominee thereof, for
investment, and not with a view toward distribution or resale, except as
permitted by the Act, and shall provide such other information to the Company as
the Company may reasonably request. Any Warrant and any Warrants issued upon
exercise of, substitution for, or upon assignment or transfer of this Warrant,
as the case may be, and all shares of Common Stock issued upon exercise hereof
or conversion thereof shall bear legends (in addition to any legend required by
state securities laws) in substantially the form set forth on the first page of
this Warrant, unless and until such securities have been transferred pursuant to
an effective registration statement under the Act or may be freely sold to the
public pursuant to Rule 144 (or any successor rule thereto) or otherwise.

     9.   Modification and Waiver.  Neither this Warrant nor any term hereof may
          -----------------------
be changed or waived other than by an instrument in writing signed by the
Company and by the holder hereof.

     10.  Notices.  Any notice, request or other document required or permitted
          -------
to be given or delivered to the holder hereof or the Company shall be delivered
or shall be sent by certified mail or documented overnight delivery service,
postage prepaid, or by telecopy, receipt acknowledged, to the Holder at its
address as shown on the books of the Company or to the Company at the address
indicated therefore in Section 2(b) of this Warrant.

     11.  Descriptive Headings and Governing Law.  The descriptive headings of
          --------------------------------------
the several sections and paragraphs of this Warrant are inserted for convenience
only and do not constitute a part of this Warrant.  This Warrant shall be
construed and enforced in accordance with, and the rights of the parties shall
be governed by, the laws of the State of Delaware.

     12.  No Impairment.  The Company will not knowingly avoid or seek to avoid
          -------------
the observance or performance of any of the terms to be observed or performed
hereunder by it, but will at all times in good faith assist in the carrying out
of all of the provisions of this Warrant.

     IN WITNESS WHEREOF, the Company has duly caused this Warrant to be signed
by its duly authorized officer and to be dated as of [_________, ___, 2000].
