full the outstanding principal balance of the Revolving Loans made to it. Each
Advance under this Section 2.1 shall consist of Revolving Loans made by each
Lender ratably in proportion to such Lender's respective Pro Rata Share.

       (B) Borrowing/Election Notice. The applicable Borrower shall deliver to
the Administrative Agent a Borrowing/Election Notice, signed by it, in
accordance with the terms of Section 2.7.

       (C) Making of Revolving Loans. Promptly after receipt of the
Borrowing/Election Notice under Section 2.7 in respect of Revolving Loans, the
Administrative Agent shall notify each Lender by telecopy, or other similar form
of transmission, of the requested Revolving Loan. Each Lender shall make
available its Revolving Loan in accordance with the terms of Section 2.6. The
Administrative Agent will promptly make the funds so received from the Lenders
available to the applicable Borrower at the Administrative Agent's office in
Chicago, Illinois on the applicable Borrowing Date and shall disburse such
proceeds in accordance with the applicable Borrower's disbursement instructions
set forth in such Borrowing/Election Notice. The failure of any Lender to
deposit the amount described above with the Administrative Agent on the
applicable Borrowing Date shall not relieve any other Lender of its obligations
hereunder to make its Revolving Loan on such Borrowing Date.

       2.2.   Swing Line Loans.

       (A) Amount of Swing Line Loans. On the terms and conditions set forth in
this Agreement and upon the satisfaction of the conditions precedent set forth
in Section 5.1, 5.2 and 5.3, as applicable, from and including the Closing Date
and prior to the Termination Date, the Swing Line Bank agrees to make swing line
loans to the Borrowers from time to time, in Dollars, in an amount not to exceed
the Swing Line Commitment (each, individually, a "SWING LINE LOAN" and
collectively, the "SWING LINE LOANS"); provided, however, at no time shall the
amount of the Revolving Credit Obligations exceed the Aggregate Commitment; and
provided, further, that at no time shall the sum of (a) the Swing Line Bank's
Pro Rata Share of the Swing Line Loans, plus (b) the outstanding amount of
Revolving Loans made by the Swing Line Bank pursuant to Section 2.1, plus (c)
the Swing Line Bank's share of the obligations to purchase participations in
Letters of Credit, exceed the Swing Line Bank's Commitment at such time. Subject
to the terms of this Agreement, the Borrowers may borrow, repay and reborrow
Swing Line Loans at any time prior to the Termination Date.

       (B) Borrowing/Election Notice. The applicable Borrower shall deliver to
the Administrative Agent and the Swing Line Bank a Borrowing/Election Notice,
signed by it, not later than 12:00 p.m. (Chicago time) on the Borrowing Date of
each Swing Line Loan, specifying (i) the applicable Borrowing Date (which date
shall be a Business Day and which may be the same date as the date the
Borrowing/Election Notice is given), and (ii) the aggregate amount of the
requested Swing Line Loan which shall be an amount not less than $100,000 (and
increments of $100,000 if in excess thereof).

                                       26

<PAGE>   37

       (C) Making of Swing Line Loans. Promptly after receipt of the
Borrowing/Election Notice under Section 2.2(B) in respect of Swing Line Loans
the Administrative Agent shall notify each Lender by telex or telecopy, or other
similar form of transmission, of the requested Swing Line Loan. Not later than
4:00 p.m. (Chicago time) on the applicable Borrowing Date, the Swing Line Bank
shall make available its Swing Line Loan, in funds immediately available in
Chicago to the Administrative Agent at its address specified pursuant to Article
XV. The Administrative Agent will promptly make the funds so received from the
Swing Line Bank available to the applicable Borrower on the Borrowing Date at
the Administrative Agent's aforesaid address. The Swing Line Loans shall be
Floating Rate Loans unless the applicable Borrower and the Swing Line Bank agree
otherwise.

       (D) Repayment of Swing Line Loans. Each Swing Line Loan shall be paid in
full by the applicable Borrower on or before the fifth (5th) Business Day after
the Borrowing Date for such Swing Line Loan. The applicable Borrower may at any
time pay, without penalty or premium, all outstanding Swing Line Loans or, in a
minimum amount of $100,000 and increments of $100,000 in excess thereof, any
portion of the outstanding Swing Line Loans, upon notice to the Administrative
Agent and the Swing Line Bank. In addition, the Administrative Agent (i) may at
any time in the sole discretion of the Swing Line Bank with respect to any
outstanding Swing Line Loan, or (ii) shall on the fifth (5th) Business Day after
the Borrowing Date of any Swing Line Loan, require each Lender (including the
Swing Line Bank) to make a Revolving Loan in the amount of such Lender's Pro
Rata Share of such Swing Line Loan, for the purpose of repaying such Swing Line
Loan. Not later than 2:00 p.m. (Chicago time) on the date of any notice received
pursuant to this Section 2.2(D), each Lender shall make available its required
Revolving Loan or Revolving Loans, in funds immediately available in Chicago to
the Administrative Agent at its address specified pursuant to Article XV.
Revolving Loans made pursuant to this Section 2.2(D) shall initially be Floating
Rate Loans and thereafter may be continued as Floating Rate Loans or converted
into Eurodollar Rate Loans in the manner provided in Section 2.9 and subject to
the other conditions and limitations therein set forth and set forth in this
Article II. Unless a Lender shall have notified the Swing Line Bank, prior to
its making any Swing Line Loan, that any applicable condition precedent set
forth in Sections 5.1, 5.2 and 5.3, as applicable, had not then been satisfied,
such Lender's obligation to make Revolving Loans pursuant to this Section 2.2(D)
to repay Swing Line Loans shall be unconditional, continuing, irrevocable and
absolute and shall not be affected by any circumstances, including, without
limitation, (a) any set-off, counterclaim, recoupment, defense or other right
which such Lender may have against the Administrative Agent, the Swing Line Bank
or any other Person, (b) the occurrence or continuance of a Default or Unmatured
Default, (c) any adverse change in the condition (financial or otherwise) of the
Company, or (d) any other circumstances, happening or event whatsoever. In the
event that any Lender fails to make payment to the Administrative Agent of any
amount due under this Section 2.2(D), the Administrative Agent shall be entitled
to receive, retain and apply against such obligation the principal and interest
otherwise payable to such Lender hereunder until the Administrative Agent
receives such payment from such Lender or such obligation is otherwise fully
satisfied. In addition to the foregoing, if for any reason any Lender fails to
make payment to the Administrative Agent of any amount due under this Section
2.2(D), such Lender shall be deemed, at the option of the Administrative Agent,
to have unconditionally and irrevocably purchased from the Swing Line Bank,
without recourse or warranty, an undivided interest and

                                       27

<PAGE>   38

participation in the applicable Swing Line Loan in the amount of such Revolving
Loan, and such interest and participation may be recovered from such Lender
together with interest thereon at the Federal Funds Effective Rate for each day
during the period commencing on the date of demand and ending on the date such
amount is received. On the Termination Date, each of the Borrowers shall repay
in full the outstanding principal balance of all Swing Line Loans made to it.

       2.3. Rate Options for all Advances; Maximum Interest Periods. The Swing
Line Loans shall be Floating Rate Loans unless the applicable Borrower and the
Swing Line Bank agree otherwise. The Revolving Loans may be Floating Rate
Advances or Eurodollar Rate Advances, or a combination thereof, selected by the
applicable Borrowers in accordance with Section 2.9. The Borrowers may select,
in accordance with Section 2.9, Rate Options and Interest Periods applicable to
portions of the Revolving Loans; provided that there shall be no more than six
(6) Interest Periods in effect with respect to all of the Loans at any time.

       2.4.   Optional Payments; Mandatory Prepayments.

       (A) Optional Payments. The Borrowers may from time to time and at any
time upon at least one (1) Business Day's prior written notice repay or prepay,
without penalty or premium all or any part of outstanding Floating Rate Advances
in an aggregate minimum amount of Four Million Dollars ($4,000,000) and in
integral multiples of One Million Dollars ($1,000,000) in excess thereof.
Eurodollar Rate Advances may be voluntarily repaid or prepaid prior to the last
day of the applicable Interest Period, subject to the indemnification provisions
contained in Section 4.4, in an aggregate minimum amount of Four Million and
00/100 Dollars ($4,000,000) and in integral multiples of One Million and 00/100
Dollars ($1,000,000) in excess thereof; provided, that the applicable Borrower
may not so prepay Eurodollar Rate Advances unless it shall have provided at
least three (3) Business Days' prior written notice to the Administrative Agent
of such prepayment and provided, further, all Eurodollar Loans constituting part
of the same Eurodollar Rate Advance shall be repaid or prepaid at the same time.

       (B) Determination of Dollar Amounts of Letters of Credit; Mandatory
Prepayments of Revolving Loans.

               (i) The Administrative Agent will determine the Dollar Amount of:

                   (a) each Letter of Credit on the date three (3) Business
               Days prior to the issuance date, or, if applicable, renewal date
               of such Letter of Credit; and

                   (b) all outstanding L/C Obligations on and as of the last
               Business Day of each calendar month and on any other Business Day
               elected by the Administrative Agent in its discretion or upon
               instruction by the Required Lenders.

Each day upon or as of which the Administrative Agent determines Dollar Amounts
as described in the preceding clauses (a) and (b) is herein described as a
"COMPUTATION DATE" with respect to each Letter of Credit for which a Dollar
Amount is determined on or as of such day.

                                       28

<PAGE>   39

               (ii)  If at any time and for any reason (other than as the result
       of fluctuations in currency exchange rates) the Dollar Amount of the
       Revolving Credit Obligations (calculated, with respect to all L/C
       Obligations denominated in Agreed Currencies other than Dollars, as of
       the most recent Computation Date with respect to each such L/C
       Obligation) is greater than the Aggregate Commitment, the Borrowers shall
       immediately make a mandatory prepayment of the Obligations in an amount
       equal to such excess. The Company shall also make all prepayments
       required under Section 2.5(B).

               (iii) If, on any Computation Date, as a result of fluctuations in
       currency exchange rates the Dollar Amount of the Revolving Credit
       Obligations exceeds one hundred five percent (105%) of the Aggregate
       Commitment, the Administrative Agent shall so notify the Company and the
       Lenders of such occurrence and the Borrowers shall immediately repay
       Revolving Loans or Swingline Loans in an aggregate principal amount
       sufficient to eliminate any such excess.

               (iv)  All of the mandatory prepayments made under this Section
       2.4(B) shall be applied first to Floating Rate Loans and to any
       Eurodollar Rate Loans maturing on such date and then to subsequently
       maturing Eurodollar Rate Loans.

       2.5.    Changes in Commitments.

       (A)     Voluntary Commitment Reductions. The Company may permanently
reduce the Aggregate Commitment in whole, or in part ratably among the Lenders,
in an aggregate minimum amount of Ten Million and 00/100 Dollars ($10,000,000)
and integral multiples of One Million and 00/100 Dollars ($1,000,000) in excess
of that amount (unless the Aggregate Commitment is reduced in whole), upon at
least three (3) Business Day's prior written notice to the Administrative Agent,
which notice shall specify the amount of any such reduction; provided, however,
that the amount of the Aggregate Commitment may not be reduced below the
aggregate principal amount of the outstanding Revolving Credit Obligations. All
accrued commitment fees shall be payable on the effective date of any
termination of all or any part of the obligations of the Lenders to make Loans
hereunder.

       (B)     Mandatory Commitment Reductions.

               (i)   Asset Sales and Sale and Leaseback Transactions. If at any
       time and for any reason the Company shall, or it shall permit any
       Subsidiary to, consummate any Asset Sale (other than Asset Sales
       permitted under Sections 7.3(B)(i), (ii), (iii) and (iv)) or Sale and
       Leaseback Transaction (other than Permitted Sale and Leaseback
       Transactions), the Aggregate Commitment shall be permanently reduced by
       an amount equal to the Net Cash Proceeds thereof and the Company shall
       immediately make a mandatory prepayment of the Obligations in an amount
       equal to such Net Cash Proceeds.

               (ii)  Financings.

               (a)   Except as provided in clause (ii)(b) below, upon the
       consummation of any Financing (other than (i) the issuance of any Equity
       Interests of the Company as consideration for the H-B Acquisition on the
       effective date of the H-B Acquisition and

                                       29

<PAGE>   40

(ii) the issuance of any Equity Interests of the Company so long as the proceeds
of such issuance shall, promptly following the Company's receipt thereof, be
paid by the Company as all or part of the consideration for any Permitted
Acquisition) by the Company or any Subsidiary of the Company, within three (3)
Business Days after the Company's or any of its Subsidiaries' receipt of any Net
Cash Proceeds from such Financing, the Company shall make a mandatory prepayment
of the Obligations in an amount equal to (x) at any time the Leverage Ratio
(determined as of the last day of the most recent fiscal quarter for which a
compliance certificate shall have been delivered in accordance with Section
7.1(A)) shall be greater than or equal to 1.00 to 1.00, 100% of such Net Cash
Proceeds, and (y) at any time the Leverage Ratio (determined as of the last day
of the most recent fiscal quarter for which a compliance certificate shall have
been delivered in accordance with Section 7.1(A)) shall be less than 1.00 to
1.00, 50% of such Net Cash Proceeds.

       (b) Notwithstanding the foregoing, Net Cash Proceeds subject to clause
(ii)(a) above shall not include Net Cash Proceeds received in connection with
(x) the issuance of any Capital Stock of the Company or any Subsidiary of the
Company, other than Disqualified Stock, to any employee, executive, director or
officer pursuant to an Incentive Arrangement, or (y) the issuance of
Indebtedness permitted to be incurred under Sections 7.3(A)(i) through (viii).

(C)    Increase in Commitments.

       (i) At any time, the Company (on behalf of itself and the other
Borrowers) may request that the Aggregate Commitment be increased (which
increase shall increase the then effective Letter of Credit sublimit set forth
in Section 3.3(i)(b) on a dollar-for- dollar basis up to a maximum sublimit of
$200,000,000); provided that, without the prior written consent of all of the
Lenders, (a) the Aggregate Commitment shall at no time exceed $300,000,000 minus
the aggregate amount of all reductions in the Aggregate Commitment previously
made pursuant to Section 2.5(A) or (B); (b) the Company shall not make any such
request during the six month period following any reduction in the Aggregate
Commitment previously made pursuant to Section 2.5(A) or (B); (c) the Company
shall not be entitled to make more than one such request during the term of this
Agreement; and (d) each such request shall be in a minimum amount of at least
$50,000,000 and increments of $1,000,000 in excess thereof. Such request shall
be made in a written notice given to the Administrative Agent and the Lenders by
the Company not less than twenty (20) Business Days prior to the proposed
effective date of such increase, which notice (a "COMMITMENT INCREASE NOTICE")
shall specify the amount of the proposed increase in the Aggregate Commitment
and the proposed effective date of such increase. In the event of such a
Commitment Increase Notice, each of the Lenders shall be given the opportunity
to participate in the requested increase ratably in proportions that their
respective Commitments bear to the Aggregate Commitment. No Lender shall have
any obligation to increase its Commitment pursuant to a Commitment Increase
Notice. On or prior to the date that is fifteen (15) Business Days after receipt
of the Commitment Increase Notice, each Lender shall submit to the
Administrative Agent a notice indicating the maximum amount by which it is
willing to increase its Commitment

                                       30

<PAGE>   41

in connection with such Commitment Increase Notice (any such notice to the
Administrative Agent being herein a "LENDER INCREASE NOTICE"). Any Lender which
does not submit a Lender Increase Notice to the Administrative Agent prior to
the expiration of such fifteen (15) Business Day period shall be deemed to have
denied any increase in its Commitment. In the event that the increases of
Commitments set forth in the Lender Increase Notices exceed the amount requested
by the Company in the Commitment Increase Notice, the Administrative Agent and
the Arranger shall have the right, in consultation with the Company, to allocate
the amount of increases necessary to meet the Company's Commitment Increase
Notice. In the event that the Lender Increase Notices are less than the amount
requested by the Company, not later than three (3) Business Days prior to the
proposed effective date the Company may notify the Administrative Agent of any
financial institution that shall have agreed to become a "Lender" party hereto
(a "PROPOSED NEW LENDER") in connection with the Commitment Increase Notice. Any
Proposed New Lender shall be consented to by the Administrative Agent (which
consent shall not be unreasonably withheld) and shall be a commercial bank
having capital and retained earnings of at least $500,000,000. If the Company
shall not have arranged any Proposed New Lender(s) to commit to the shortfall
from the Lender Increase Notices, then the Company shall be deemed to have
reduced the amount of its Commitment Increase Notice to the aggregate amount set
forth in the Lender Increase Notices. Based upon the Lender Increase Notices,
any allocations made in connection therewith and any notice regarding any
Proposed New Lender, if applicable, the Administrative Agent shall notify the
Company and the Lenders on or before the Business Day immediately prior to the
proposed effective date of the amount of each Lender's and Proposed New Lenders'
Commitment (the "EFFECTIVE COMMITMENT AMOUNT") and the amount of the Aggregate
Commitment, which amounts shall be effective on the following Business Day. Any
increase in the Aggregate Commitment shall be subject to the following
conditions precedent: (A) the Company shall have obtained the consent thereto of
each Guarantor and its reaffirmation of the Loan Document(s) executed by it,
which consent and reaffirmation shall be in writing and in form and substance
reasonably satisfactory to the Administrative Agent, (B) as of the date of the
Commitment Increase Notice and as of the proposed effective date of the increase
in the Aggregate Commitment all representations and warranties shall be true and
correct in all material respects as though made on such date and no event shall
have occurred and then be continuing which constitutes a Default or Unmatured
Default, (C) the Borrowers, the Administrative Agent and each Proposed New
Lender or Lender that shall have agreed to provide a "Commitment" in support of
such increase in the Aggregate Commitment shall have executed and delivered a
"Commitment and Acceptance" substantially in the form of Exhibit M hereto, (D)
counsel for the Company and for the Guarantors shall have provided to the
Administrative Agent supplemental opinions in form and substance reasonably
satisfactory to the Administrative Agent and (E) the Borrowers and the Proposed
New Lender shall otherwise have executed and delivered such other instruments
and documents as may be required under Article V or that the Administrative
Agent shall have reasonably requested in connection with such increase. If any
fee shall be charged by the Lenders in connection with any such increase, such
fee shall be in accordance with then prevailing market conditions, which market
conditions shall have been reasonably documented by the Administrative Agent

                                       31

<PAGE>   42

to the Company. Upon satisfaction of the conditions precedent to any increase in
the Aggregate Commitment, the Administrative Agent shall promptly advise the
Company and each Lender of the effective date of such increase. Upon the
effective date of any increase in the Aggregate Commitment that is supported by
a Proposed New Lender, such Proposed New Lender shall be a party to this
Agreement as a Lender and shall have the rights and obligations of a Lender
hereunder and thereunder. Nothing contained herein shall constitute, or
otherwise be deemed to be, a commitment on the part of any Lender to increase
its Commitment hereunder at any time.

       (ii) For purposes of this clause (ii), (A) the term "BUYING LENDER(S)"
shall mean (1) each Lender the Effective Commitment Amount of which is greater
than its Commitment prior to the effective date of any increase in the Aggregate
Commitment and (2) each Proposed New Lender that is allocated an Effective
Commitment Amount in connection with any Commitment Increase Notice and (b) the
term "SELLING LENDER(S)" shall mean each Lender whose Commitment is not being
increased from that in effect prior to such increase in the Aggregate
Commitment. Effective on the effective date of any increase in the Aggregate
Commitment pursuant to clause (i) above, each Selling Lender hereby sells,
grants, assigns and conveys to each Buying Lender, without recourse, warranty,
or representation of any kind, except as specifically provided herein, an
undivided percentage in such Selling Lender's right, title and interest in and
to its outstanding Loans in the respective Dollar Amounts and percentages
necessary so that, from and after such sale, each such Selling Lender's
outstanding Loans shall equal such Selling Lender's Pro Rata Share (calculated
based upon the Effective Commitment Amounts) of the outstanding Loans. Effective
on the effective date of the increase in the Aggregate Commitment pursuant to
clause (i) above, each Buying Lender hereby purchases and accepts such grant,
assignment and conveyance from the Selling Lenders. Each Buying Lender hereby
agrees that its respective purchase price for the portion of the outstanding
Loans purchased hereby shall equal the respective Dollar Amount necessary so
that, from and after such payments, each Buying Lender's outstanding Loans shall
equal such Buying Lender's Pro Rata Share (calculated based upon the Effective
Commitment Amounts) of the outstanding Loans. Such amount shall be payable on
the effective date of the increase in the Aggregate Commitment by wire transfer
of immediately available funds to the Administrative Agent. The Administrative
Agent, in turn, shall wire transfer any such funds received to the Selling
Lenders, in same day funds, for the sole account of the Selling Lenders. Each
Selling Lender hereby represents and warrants to each Buying Lender that such
Selling Lender owns the Loans being sold and assigned hereby for its own account
and has not sold, transferred or encumbered any or all of its interest in such
Loans, except for participations which will be extinguished upon payment to
Selling Lender of an amount equal to the portion of the outstanding Loans being
sold by such Selling Lender. Each Buying Lender hereby acknowledges and agrees
that, except for each Selling Lender's representations and warranties contained
in the foregoing sentence, each such Buying Lender has entered into its
Commitment and Acceptance with respect to such increase on the basis of its own
independent investigation and has not relied upon, and will not rely upon, any
explicit or implicit written or oral representation, warranty or other statement
of the Lenders or the Administrative Agent concerning the authorization,
execution, legality, validity,

                                       32

<PAGE>   43

       effectiveness, genuineness, enforceability or sufficiency of this
       Agreement or the other Loan Documents. The Company hereby agrees to
       compensate each Selling Lender for all losses, expenses and liabilities
       incurred by each Lender in connection with the sale and assignment of any
       Eurodollar Loan hereunder on the terms and in the manner as set forth in
       Section 3.4.

       2.6. Method of Borrowing. On each Borrowing Date, each Lender shall make
available its Revolving Loan or Revolving Loans, if any, not later than noon,
Chicago time, in Federal or other funds immediately available to the
Administrative Agent, in Chicago, Illinois at its address specified in or
pursuant to Article XV. Unless the Administrative Agent determines that any
applicable condition specified in Article V has not been satisfied, the
Administrative Agent will make the funds so received from the Lenders available
to the applicable Borrower at the Administrative Agent's aforesaid address.

       2.7. Method of Selecting Types and Interest Periods for Advances. The
applicable Borrower shall select the Type of Advance and, in the case of each
Eurodollar Rate Advance, the Interest Period applicable to each Advance from
time to time. The applicable Borrower shall give the Administrative Agent
irrevocable notice in substantially the form of Exhibit B hereto (a
"BORROWING/ELECTION NOTICE") not later than 10:00 a.m. (Chicago time) (a) on or
before the Borrowing Date of each Floating Rate Advance, (b) three (3) Business
Days before the Borrowing Date for each Eurodollar Rate Advance. The Borrowers
shall select Interest Periods so that, to the best of their knowledge, it will
not be necessary to prepay all or any portion of any Eurodollar Rate Loan prior
to the last day of the applicable Interest Period in order to make mandatory
prepayments as required pursuant to the terms hereof. Each Floating Rate Advance
and all Obligations other than Loans shall bear interest from and including the
date of the making of such Advance, in the case of Loans, and the date such
Obligation is due and owing in the case of such other Obligations, to (but not
including) the date of repayment thereof at the Floating Rate changing when and
as such Floating Rate changes. Changes in the rate of interest on that portion
of any Advance maintained as a Floating Rate Loan will take effect
simultaneously with each change in the Alternate Base Rate. Each Eurodollar Rate
Advance shall bear interest from and including the first day of the Interest
Period applicable thereto to (but not including) the last day of such Interest
Period at the interest rate determined as applicable to such Eurodollar Rate
Advance and shall change as and when the Applicable Eurodollar Margin changes.

       2.8. Minimum Amount of Each Advance. Each Advance (other than an Advance
to repay Swing Line Loans or a Reimbursement Obligation) shall be in the minimum
amount of Four Million Dollars ($4,000,000) and in multiples of One Million
Dollars ($1,000,000) if in excess thereof, provided, however, that any Floating
Rate Advance may be in the amount of the unused Aggregate Commitment.

       2.9. Method of Selecting Types and Interest Periods for Conversion and
Continuation of Advances.

       (A) Right to Convert. The applicable Borrower may elect from time to
time, subject to the provisions of Section 2.3 and this Section 2.9, to convert
all or any part of a Loan of any Type into any other Type or Types of Loans;
provided that any conversion of any Eurodollar

                                       33

<PAGE>   44

Rate Advance shall be made on, and only on, the last day of the Interest Period
applicable thereto.

       (B) Automatic Conversion and Continuation. Floating Rate Loans shall
continue as Floating Rate Loans unless and until such Floating Rate Loans are
converted into Eurodollar Rate Loans. Eurodollar Rate Loans shall continue as
Eurodollar Rate Loans until the end of the then applicable Interest Period
therefor, at which time such Eurodollar Rate Loans shall be automatically
converted into Floating Rate Loans unless such Eurodollar Rate Loans shall have
been repaid or the Company shall have given the Administrative Agent notice in
accordance with Section 2.9 (D) requesting that, at the end of such Interest
Period, such Eurodollar Rate Loans continue as a Eurodollar Rate Loan.

       (C) No Conversion Post-Default or Post-Unmatured Default. Notwithstanding
anything to the contrary contained in Section 2.9(A) or Section 2.9(B), no Loan
may be converted into or continued as a Eurodollar Rate Loan (except with the
consent of the Required Lenders) when any Default or Unmatured Default has
occurred and is continuing.

       (D) Borrowing/Election Notice. The Company shall give the Administrative
Agent an irrevocable Borrowing/Election Notice of each conversion of a Floating
Rate Loan into a Eurodollar Rate Loan or continuation of a Eurodollar Rate Loan
not later than 10:00 a.m. (Chicago time) (x) one (1) Business Day prior to the
date of the requested conversion or continuation, with respect to any Loan to be
converted to or continued as a Floating Rate Advance, and (y) three (3) Business
Days prior to the date of the requested conversion or continuation, with respect
to any Loan to be converted or continued as a Eurodollar Rate Loan, specifying:
(1) the requested date (which shall be a Business Day) of such conversion or
continuation; (2) the amount and Type of the Loan to be converted or continued;
and (3) if applicable, the amount of Eurodollar Rate Loan(s) into which such
Loan is to be converted or continued and the duration of the Interest Period
applicable thereto.

       2.10. Default Rate. After the occurrence and during the continuance of a
Default, at the option of the Administrative Agent or at the direction of the
Required Lenders the interest rate(s) applicable to the Obligations and all
other fees (including the fees payable under Section 3.8 with respect to Letters
of Credit) shall be equal to (x) the interest rates and fees calculated based on
the maximum Applicable Floating Rate Margins, Applicable Eurodollar Margin and
Applicable Commitment Fee Percentage, as applicable, under the pricing grid set
forth in Section 2.14(D)(ii) plus (y) two percent (2.00%) per annum for all such
Obligations and fees; provided that during the continuation of a bankruptcy or
insolvency default such interest rate and fee increases shall be automatically
applicable without any election of the Administrative Agent or action of the
Required Lenders.

       2.11.  Method of Payment.

       (A) Method of Payment. All payments of principal, interest, fees,
reimbursements, commissions, L/C Obligations and other Obligations hereunder
shall be made, without setoff, deduction or counterclaim (unless indicated
otherwise in Section 2.14(E)), in immediately available funds to the
Administrative Agent at the Administrative Agent's address specified

                                       34

<PAGE>   45

pursuant to Article XV, or at any other Lending Installation of the applicable
Issuing Bank specified in writing by such Issuing Bank to the applicable
Borrower in connection with any Letter of Credit issued in an Agreed Currency
other than Dollars. Each Advance shall be repaid or prepaid in Dollars in the
amount equal to the amount borrowed and interest payable thereon shall also be
paid in Dollars. Each L/C Obligation denominated in an Agreed Currency other
than Dollars shall be repaid, and all interest and fees to be paid in respect
thereof shall be paid, in the currency in which the related Letter of Credit was
issued or, where such currency has converted to euro, in euro. All payments to
be made by any Borrower hereunder in any currency other than Dollars shall be
made in such currency on the date due in such funds as may then be customary for
the settlement of international transactions in such currency for the account of
the Administrative Agent or applicable Issuing Bank, as applicable, at its
designated Lending Installation for such currency. Each payment delivered to the
Administrative Agent for the account of any Lender shall be delivered promptly
by the Administrative Agent to such Lender in the same type of funds that the
Administrative Agent received at its address specified pursuant to Article XV or
at any Lending Installation specified in a notice received by the Administrative
Agent from such Lender. The Administrative Agent is hereby authorized to charge
any account of the applicable Borrower maintained with Bank One or any of its
Affiliates for each payment of principal, interest and fees as it becomes due
hereunder. Each reference to the Administrative Agent in this Section 2.11 shall
also be deemed to refer, and shall apply equally, to each Issuing Bank, in the
case of payments required to be made by any Borrower to any Issuing Bank
pursuant to Article III.

       (B) Market Disruption. If, after the designation by the applicable
Issuing Bank and the Administrative Agent of any currency as an Agreed Currency,
in the reasonable opinion of any Borrower, any Issuing Bank, the Required
Lenders or the Administrative Agent, (x) there shall occur any change in
national or international financial, political or economic conditions or
currency exchange rates or currency control or other exchange regulations are
imposed in the country which issues such currency with the result that it shall
be impractical for any L/C Obligation to be denominated in such currency or
different types of such currency are introduced, (y) such currency is no longer
readily available or freely traded or (z) an Equivalent Amount of such currency
is not readily calculable (any such event a "MARKET DISRUPTION"), such Borrower,
such Issuing Bank, the Required Lenders or the Administrative Agent, as
applicable, shall promptly notify the Lenders, the Issuing Banks, the
Administrative Agent and the Borrowers, and such currency shall no longer be an
Agreed Currency until such time as the Administrative Agent and any applicable
Issuing Bank agrees to reinstate such currency as an Agreed Currency, and all
payments to be made by the applicable Borrower hereunder in such currency shall
instead be made when due in Dollars in an amount equal to the Dollar Amount (as
of the date of repayment) of such payment due, it being the intention of the
parties hereto that the Borrowers take all risks of the imposition of any such
currency control or exchange regulations. For purposes of this Section 2.11(B),
the commencement of the third stage of the European Economic and Monetary Union
shall not constitute the imposition of currency control or exchange regulations.

       2.12.  Evidence of Debt.

                                       35
<PAGE>   46

       (A) Loan Account. Each Lender shall maintain in accordance with its usual
practice an account or accounts (a "Loan Account") evidencing the indebtedness
of the Borrowers to such Lender owing to such Lender from time to time,
including the amounts of principal and interest payable and paid to such Lender
from time to time hereunder.

       (B) Register. The Register maintained by the Administrative Agent
pursuant to Section 14.3(C) shall include a control account, and a subsidiary
account for each Lender and each Borrower, in which accounts (taken together)
shall be recorded (i) the date and the amount of each Loan made hereunder, the
Type thereof and the Interest Period, if any, applicable thereto, (ii) the
amount of any principal or interest due and payable or to become due and payable
from each of the Borrowers to each Lender hereunder, (iii) the effective date
and amount of each Assignment Agreement delivered to and accepted by it and the
parties thereto pursuant to Section 14.3, (iv) the amount of any sum received by
the Administrative Agent hereunder for the account of the Lenders and each
Lender's share thereof, and (v) all other appropriate debits and credits as
provided in this Agreement, including, without limitation, all fees, charges,
expenses and interest.

       (C) Entries in Loan Account and Register. The entries made in the Loan
Account, the Register and the other accounts maintained pursuant to clauses (A)
or (B) of this Section shall be prima facie evidence thereof for all purposes,
absent manifest error, unless the applicable Borrower objects to information
contained in the Loan Accounts, the Register or the other accounts within thirty
(30) days of the applicable Borrower's receipt of such information; provided
that the failure of any Lender or the Administrative Agent to maintain such
accounts or any error therein shall not in any manner affect the obligation of
the Borrowers to repay the Loans in accordance with the terms of this Agreement.

       (D) Noteless Transaction; Notes Issued Upon Request. Any Lender may
request that the Revolving Loans made or to be made by it each be evidenced by a
promissory note in substantially the form of Exhibit J to evidence such Lender's
Revolving Loans. In such event, the Borrowers shall prepare, execute and deliver
to such Lender a promissory note for such Loans payable to the order of such
Lender. Thereafter, the Loans evidenced by such promissory note and interest
thereon shall at all times (including after assignment pursuant to Section 14.3)
be represented by one or more promissory notes in such form payable to the order
of the payee named therein.

       2.13.  Telephonic Notices. The Borrowers authorize the Lenders and the
Administrative Agent to extend, convert or continue Advances, effect selections
of Types of Advances and to transfer funds based on telephonic notices made by
any person or persons the Administrative Agent or any Lender in good faith
believes to be acting on behalf of the applicable Borrower. Each of the
Subsidiary Borrowers authorizes the Company to make requests and give notices
hereunder on behalf of such Subsidiary Borrowers. The Borrowers agree to deliver
promptly to the Administrative Agent a written confirmation, signed by an
Authorized Officer, if such confirmation is requested by the Administrative
Agent or any Lender, of each telephonic notice. If the written confirmation
differs in any material respect from the action taken by the Administrative
Agent and the Lenders, the records of the Administrative Agent and the Lenders
shall govern absent manifest error. In case of disagreement concerning such
notices, if the

                                       36
<PAGE>   47

Administrative Agent has recorded telephonic borrowing notices, such recordings
will be made available to the applicable Borrower upon its request therefor.

       2.14.  Promise to Pay; Interest and Commitment Fees; Interest Payment
Dates; Interest and Fee Basis; Taxes; Loan and Control Accounts.

       (A)    Promise to Pay. All Advances shall be paid in full by the
applicable Borrowers on the Termination Date. Each Borrower unconditionally
promises to pay when due the principal amount of each Loan and all other
Obligations incurred by it, and to pay all unpaid interest accrued thereon, in
accordance with the terms of this Agreement and the other Loan Documents, and
confirms that all Borrowers (other than Borrowers which are Foreign
Subsidiaries) shall be jointly and severally liable for all of the Obligations.

       (B)    Interest Payment Dates. Interest accrued on each Floating Rate
Loan shall be payable on each Payment Date, commencing with the first such date
to occur after the date hereof, upon any prepayment whether by acceleration or
otherwise, and at maturity (whether by acceleration or otherwise). Interest
accrued on each Eurodollar Rate Loan shall be payable on the last day of its
applicable Interest Period, on any date on which the Eurodollar Rate Loan is
prepaid, whether by acceleration or otherwise, and at maturity; provided,
interest accrued on each Eurodollar Rate Loan having an Interest Period longer
than three months shall also be payable on the last day of each three-month
interval during such Interest Period. Interest accrued on the principal balance
of all other Obligations shall be payable in arrears (i) on the last day of each
calendar quarter, commencing on the first such day following the incurrence of
such Obligation, (ii) upon repayment thereof in full or in part, and (iii) if
not theretofore paid in full, at the time such other Obligation becomes due and
payable (whether by acceleration or otherwise).

       (C)    Commitment Fees; Additional Fees.

              (i) The Company shall pay to the Administrative Agent, for the
       account of the Lenders in accordance with their Pro Rata Shares, from and
       after the Closing Date until the date on which the Aggregate Commitment
       shall be terminated in whole, a commitment fee at the rate of the then
       Applicable Commitment Fee Percentage multiplied by the average amount by
       which (A) the Aggregate Commitment in effect from time to time exceeds
       (B) the Revolving Credit Obligations (excluding the outstanding principal
       amount of the Swing Line Loans) in effect from time to time during each
       fiscal quarter of the Company. All such commitment fees payable under
       this clause (C) shall be payable quarterly on the last day of each fiscal
       quarter of the Company occurring after the Closing Date (with the first
       such payment being calculated for the period from the Closing Date and
       ending on December 31, 2000), and, in addition, on any date on which the
       Aggregate Commitment shall be terminated in whole.

              (ii) The Company agrees to pay or to cause the Borrowers to pay
       to the Administrative Agent for the sole account of the Administrative
       Agent and the Arranger (unless otherwise agreed between the
       Administrative Agent and the Arranger and any Lender) the fees set forth
       in the letter agreement between the Administrative Agent, the

                                       37
<PAGE>   48

       Arranger and the Company dated August 18, 2000, payable at the times and
       in the amounts set forth therein.

       (D)    Interest and Fee Basis; Applicable Floating Rate Margins,
Applicable Eurodollar Margin, Applicable L/C Fee Percentage and Applicable
Commitment Fee Percentage.

              (i) Interest on all fees, Eurodollar Rate Loans and Alternate
       Base Rate Loans calculated by reference to the Federal Fund Effective
       Rate shall be calculated for actual days elapsed on the basis of a
       360-day year; provided, that the Applicable L/C Fee Percentage applicable
       to Letters of Credit issued in British Pounds Sterling, if any, shall be
       calculated for actual days elapsed on the basis of a 365-day year.
       Interest on all Alternate Base Rate Loans calculated by reference to the
       Prime Rate shall be calculated for actual days elapsed on the basis of a
       365/366-day year. Interest shall be payable for the day an Obligation is
       incurred but not for the day of any payment on the amount paid if payment
       is received prior to 2:00 p.m. (Chicago time or local time, as
       applicable) at the place of payment. If any payment of principal of or
       interest on a Loan or any payment of any other Obligations shall become
       due on a day which is not a Business Day, such payment shall be made on
       the next succeeding Business Day and, in the case of a principal payment,
       such extension of time shall be included in computing interest, fees and
       commissions in connection with such payment.

              (ii) The Applicable Floating Rate Margins, Applicable Eurodollar
       Margin, Applicable L/C Fee Percentage and Applicable Commitment Fee
       Percentage shall be determined from time to time by reference to the
       table set forth below, on the basis of the then applicable Leverage Ratio
       as described in this Section 2.14(D)(ii):

       For purposes of this Section 2.15(D)(ii), the Leverage Ratio shall be
       calculated as provided in Section 7.4(A). Upon receipt of the financial
       statements delivered pursuant

                                       38
<PAGE>   49

       to Sections 7.1(A)(i) and (ii), as applicable, the Applicable Floating
       Rate Margins, Applicable Eurodollar Margin, Applicable L/C Fee Percentage
       and Applicable Commitment Fee Percentage shall be adjusted, such
       adjustment being effective five (5) Business Days following the date such
       financial statements and the compliance certificate required to be
       delivered in connection therewith pursuant to Section 7.1(A)(iii) shall
       be due; provided, that if the Company shall not have timely delivered its
       financial statements in accordance with Section 7.1(A)(i) or (ii), as
       applicable, then commencing on the date upon which such financial
       statements should have been delivered and continuing until five (5)
       Business Days following the date such financial statements are actually
       delivered, the Applicable Floating Rate Margins, Applicable Eurodollar
       Margin, Applicable L/C Fee Percentage and Applicable Commitment Fee
       Percentage shall be the maximum Applicable Floating Rate Margins,
       Applicable Eurodollar Margin and Applicable Commitment Fee Percentage, as
       applicable, under the pricing grid set forth in Section 2.14(D)(ii).

               (iii) Notwithstanding anything herein to the contrary, from the
       Closing Date to but not including the fifth (5th) Business Day following
       receipt of the Company's audited financial statements delivered pursuant
       to Section 7.1(A)(i) (and accompanying officer's certificate) for the
       fiscal quarter ended December 31, 2000, the Applicable Floating Rate
       Margins, Applicable Eurodollar Margin and Applicable Commitment Fee
       Percentage shall be determined based upon a Leverage Ratio of greater
       than or equal to 1.50 to 1.00 and less than 2.00 to 1.00 at which time
       the Applicable Floating Rate Margins, Applicable Eurodollar Margin and
       Applicable Commitment Fee Percentage shall be determined based on such
       financial statements and officer's certificate delivered therewith.

       (E)    Taxes.

              (i)    Any and all payments by the Borrowers hereunder (whether in
       respect of principal, interest, fees or otherwise) shall be made free and
       clear of and without deduction for any and all present or future taxes,
       levies, imposts, deductions, charges or withholdings or any interest,
       penalties and liabilities with respect thereto including those arising
       after the date hereof as a result of the adoption of or any change in any
       law, treaty, rule, regulation, guideline or determination of a
       Governmental Authority or any change in the interpretation or application
       thereof by a Governmental Authority but excluding, in the case of each
       Lender and the Administrative Agent, such taxes (including income taxes,
       franchise taxes and branch profit taxes) as are imposed on or measured by
       such Lender's or the Administrative Agent's, as the case may be, net
       income by the United States of America or any Governmental Authority of
       the jurisdiction under the laws of which such Lender or the
       Administrative Agent, as the case may be, is organized (all such
       non-excluded taxes, levies, imposts, deductions, charges, withholdings,
       and liabilities which the Administrative Agent or a Lender determines to
       be applicable to this Agreement, the other Loan Documents, the
       Commitments, the Loans or the Letters of Credit being hereinafter
       referred to as "TAXES"). If any Borrower shall be required by law to
       deduct or withhold any Taxes from or in respect of any sum payable
       hereunder or under the other Loan Documents to any Lender or the
       Administrative Agent, (i) the sum

                                       39
<PAGE>   50

       payable shall be increased as may be necessary so that after making all
       required deductions or withholdings (including deductions applicable to
       additional sums payable under this Section 2.14(E)) such Lender or
       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 applicable Borrower shall make such deductions or
       withholdings, and (iii) the applicable Borrower shall pay the full amount
       deducted or withheld to the relevant taxation authority or other
       authority in accordance with applicable law. If a withholding tax of the
       United States of America or any other Governmental Authority shall be or
       become applicable (y) after the date of this Agreement, to such payments
       by the applicable Borrower made to the Lending Installation or any other
       office that a Lender may claim as its Lending Installation, or (z) after
       such Lender's selection and designation of any other Lending
       Installation, to such payments made to such other Lending Installation,
       such Lender shall use reasonable efforts to make, fund and maintain the
       affected Loans through another Lending Installation of such Lender in
       another jurisdiction so as to reduce the applicable Borrower's liability
       hereunder, if the making, funding or maintenance of such Loans through
       such other Lending Installation of such Lender does not, in the judgment
       of such Lender, otherwise adversely affect such Loans, or obligations
       under the Commitment of such Lender.

              (ii)   In addition, the Borrowers agree to pay any present or
       future stamp or documentary taxes or any other excise or property taxes,
       charges, or similar levies which arise from any payment made hereunder,
       from the issuance of Letters of Credit hereunder, or from the execution,
       delivery or registration of, or otherwise with respect to, this
       Agreement, the other Loan Documents, the Commitments, the Loans or the
       Letters of Credit (hereinafter referred to as "OTHER TAXES").

              (iii)  The Company and each Subsidiary Borrower shall indemnify
       each Lender and the Administrative Agent for the full amount of Taxes and
       Other Taxes (including, without limitation, any Taxes or Other Taxes
       imposed by any Governmental Authority on amounts payable under this
       Section 2.14(E)) paid by such Lender or the Administrative Agent (as the
       case may be) and any liability (including penalties, interest, and
       expenses) arising therefrom or with respect thereto, whether or not such
       Taxes or Other Taxes were correctly or legally asserted. This
       indemnification shall be made within thirty (30) days after the date such
       Lender or the Administrative Agent (as the case may be) makes written
       demand therefor. If the Taxes or Other Taxes with respect to which the
       Company or any Subsidiary Borrower has made either a direct payment to
       the taxation or other authority or an indemnification payment hereunder
       are subsequently refunded to any Lender, such Lender will return to the
       applicable Borrower, if no Event of Default has occurred and is
       continuing, an amount equal to the lesser of the indemnification payment
       or the refunded amount. A certificate as to any additional amount payable
       to any Lender or the Administrative Agent under this Section 2.14(E)
       submitted to the applicable Borrower and the Administrative Agent (if a
       Lender is so submitting) by such Lender or the Administrative Agent shall
       show in reasonable detail the amount payable and the calculations used to
       determine such amount and shall, absent manifest error, be final,
       conclusive and binding upon all parties hereto. With respect to such
       deduction or

                                       40

<PAGE>   51

       withholding for or on account of any Taxes and to confirm that all such
       Taxes have been paid to the appropriate Governmental Authorities, the
       applicable Borrower shall promptly (and in any event not later than
       thirty (30) days after receipt) furnish to each Lender and the
       Administrative Agent such certificates, receipts and other documents as
       may be required (in the reasonable judgment of such Lender or the
       Administrative Agent) to establish any tax credit to which such Lender or
       the Administrative Agent may be entitled.

              (iv)   Within thirty (30) days after the date of any payment of
       Taxes or Other Taxes by the Company or any Subsidiary Borrower, the
       Company shall furnish to the Administrative Agent the original or a
       certified copy of a receipt evidencing payment thereof.

              (v)    Without prejudice to the survival of any other agreement of
       the Company and the Subsidiary Borrowers hereunder, the agreements and
       obligations of the Borrowers contained in this Section 2.14(E) shall
       survive the payment in full of all Obligations, the termination of the
       Letters of Credit and the termination of this Agreement.

              (vi)   Each Lender (including any Replacement Lender or Purchaser)
       that is not created or organized under the laws of the United States of
       America or a political subdivision thereof (each a "NON-U.S. LENDER")
       shall deliver to the Company and the Administrative Agent on or before
       the Closing Date, or, if later, the date on which such Lender becomes a
       Lender pursuant to Section 14.3 hereof (and from time to time thereafter
       upon the request of the Company or the Administrative Agent, but only for
       so long as such Non-U.S. Lender is legally entitled to do so), either (1)
       two (2) duly completed copies of either (A) IRS Form W-8BEN, or (B) IRS
       Form W-8ECI, or in either case an applicable successor form; or (2) in
       the case of a Non-U.S. Lender that is not legally entitled to deliver the
       forms listed in clause (vi)(1), (x) a certificate of a duly authorized
       officer of such Non-U.S. Lender to the effect that such Non-U.S. Lender
       is not (A) a "bank" within the meaning of Section 881(c)(3)(A) of the
       Code, (B) a "10 percent shareholder" of the Company or any Subsidiary
       Borrower within the meaning of Section 881(c)(3)(B) of the Code, or (C) a
       controlled foreign corporation receiving interest from a related person
       within the meaning of Section 881(c)(3)(C) of the Code (such certificate,
       an "EXEMPTION CERTIFICATE") and (y) two (2) duly completed copies of IRS
       Form W-8BEN or applicable successor form. Each such Lender further
       agrees to deliver to the Company and the Administrative Agent from time
       to time a true and accurate certificate executed in duplicate by a duly
       authorized officer of such Lender in a form satisfactory to the Company
       and the Administrative Agent, before or promptly upon the occurrence of
       any event requiring a change in the most recent certificate previously
       delivered by it to the Company and the Administrative Agent pursuant to
       this Section 2.14(E)(vi). Further, each Lender which delivers a form or
       certificate pursuant to this clause (vi) covenants and agrees to deliver
       to the Company and the Administrative Agent within fifteen (15) days
       prior to the expiration of such form, for so long as this Agreement is
       still in effect, another such certificate and/or two (2) accurate and
       complete original newly-signed

                                       41
<PAGE>   52

       copies of the applicable form (or any successor form or forms required
       under the Code or the applicable regulations promulgated thereunder).

              Each Lender shall promptly furnish to the Company and the
       Administrative Agent such additional documents as may be reasonably
       required by any Borrower or the Administrative Agent to establish any
       exemption from or reduction of any Taxes or Other Taxes required to be
       deducted or withheld and which may be obtained without undue expense to
       such Lender. Notwithstanding any other provision of this Section 2.14(E),
       no Borrower shall be obligated to gross up any payments to any Lender
       pursuant to Section 2.14(E)(i), or to indemnify any Lender pursuant to
       Section 2.14(E)(iii), in respect of United States federal withholding
       taxes to the extent imposed as a result of (x) the failure of such Lender
       to deliver to the Company the form or forms and/or an Exemption
       Certificate, as applicable to such Lender, pursuant to Section
       2.14(E)(vi), (y) such form or forms and/or Exemption Certificate not
       establishing a complete exemption from U.S. federal withholding tax or
       the information or certifications made therein by the Lender being untrue
       or inaccurate on the date delivered in any material respect, or (z) the
       Lender designating a successor Lending Installation at which it maintains
       its Loans which has the effect of causing such Lender to become obligated
       for tax payments in excess of those in effect immediately prior to such
       designation; provided, however, that the applicable Borrower shall be
       obligated to gross up any payments to any such Lender pursuant to Section
       2.14(E)(i), and to indemnify any such Lender pursuant to Section
       2.14(E)(iii), in respect of United States federal withholding taxes if
       (i) any such failure to deliver a form or forms or an Exemption
       Certificate or the failure of such form or forms or exemption certificate
       to establish a complete exemption from U.S. federal withholding tax or
       inaccuracy or untruth contained therein resulted from a change in any
       applicable statute, treaty, regulation or other applicable law or any
       interpretation of any of the foregoing occurring after the date hereof,
       which change rendered such Lender no longer legally entitled to deliver
       such form or forms or Exemption Certificate or otherwise ineligible for a
       complete exemption from U.S. federal withholding tax, or rendered the
       information or the certifications made in such form or forms or Exemption
       Certificate untrue or inaccurate in any material respect, (ii) the
       redesignation of the Lender's Lending Installation was made at the
       request of the Company or (iii) the obligation to gross up payments to
       any such Lender pursuant to Section 2.14(E)(i), or to indemnify any such
       Lender pursuant to Section 2.14(E)(iii), is with respect to a Purchaser
       that becomes a Purchaser as a result of an assignment made at the request
       of the Company.

              (vii)  Upon the request, and at the expense of the Company, each
       Lender to which any Borrower is required to pay any additional amount
       pursuant to this Section 2.14(E), shall reasonably afford the applicable
       Borrower the opportunity to contest, and shall reasonably cooperate with
       the applicable Borrower in contesting, the imposition of any Tax giving
       rise to such payment; provided, that (i) such Lender shall not be
       required to afford the applicable Borrower the opportunity to so contest
       unless the applicable Borrower shall have confirmed in writing to such
       Lender its obligation to pay such amounts pursuant to this Agreement; and
       (ii) the Company shall reimburse such Lender for its reasonable
       attorneys' and accountants' fees and disbursements incurred in so
       cooperating with the applicable Borrower in contesting the imposition of
       such Tax.

                                       42

<PAGE>   53

       2.15.  Notification of Advances, Interest Rates, Prepayments and
Aggregate Commitment Reductions. Promptly after receipt thereof, the
Administrative Agent will notify each Lender of the contents of each Aggregate
Commitment reduction notice, Borrowing/Election Notice, and repayment notice
received by it hereunder. The Administrative Agent will notify the applicable
Borrower and each Lender of the interest rate applicable to each Eurodollar Rate
Loan promptly upon determination of such interest rate and will give each Lender
prompt notice of each change in the Alternate Base Rate.

       2.16.  Lending Installations. Each Lender will book its Loans or Letters
of Credit at the appropriate Lending Installation listed on the administrative
information sheets provided to the Administrative Agent in connection herewith
or such other Lending Installation designated by such Lender in accordance with
the final sentence of this Section 2.16. All terms of this Agreement shall apply
to any such Lending Installation. Each Lender may, by written or facsimile
notice to the Administrative Agent and the Company, designate a Lending
Installation through which Loans will be made by it and for whose account Loan
payments and/or payments of L/C Obligations are to be made.

       2.17.  Non-Receipt of Funds by the Administrative Agent. Unless a
Borrower or a Lender, as the case may be, notifies the Administrative Agent
prior to the date on which it is scheduled to make payment to the Administrative
Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case
of any Borrower, a payment of principal, interest or fees to the Administrative
Agent for the account of the Lenders, that it does not intend to make such
payment, the Administrative Agent may assume that such payment has been made.
The Administrative Agent may, but shall not be obligated to, make the amount of
such payment available to the intended recipient in reliance upon such
assumption. If such Lender or the applicable Borrower, as the case may be, has
not in fact made such payment to the Administrative Agent, the recipient of such
payment shall, on demand by the Administrative Agent, repay to the
Administrative Agent the amount so made available together with interest thereon
in respect of each day during the period commencing on the date such amount was
so made available by the Administrative Agent until the date the Administrative
Agent recovers such amount at a rate per annum equal to (i) in the case of
payment by a Lender, the Federal Funds Effective Rate for such day or (ii) in
the case of payment by a Borrower, the interest rate applicable to the relevant
Loan.

       2.18.  Termination Date. This Agreement shall be effective until the
Termination Date. Notwithstanding the termination of this Agreement, until (A)
all financing arrangements among the Borrowers and the Lenders shall have been
terminated and (B) all of the Letters of Credit shall have expired, been
cancelled or terminated, or cash collateralized pursuant to the terms of this
Agreement or supported by a letter of credit acceptable to the Administrative
Agent (collectively, the "TERMINATION CONDITIONS"), all of the rights and
remedies under this Agreement and the other Loan Documents shall survive.

       2.19.  Replacement of Certain Lenders. In the event a Lender ("AFFECTED
LENDER") shall have: (i) failed to fund its Applicable Pro Rata Share of any
Advance requested by the applicable Borrower, or to fund a Revolving Loan in
order to repay Swing Line Loans pursuant to Section 2.2(D), which such Lender is
obligated to fund under the terms of this Agreement and

                                       43

<PAGE>   54
which failure has not been cured, (ii) requested compensation from any Borrower
under Sections 2.14(E), 4.1 or 4.2 to recover Taxes, Other Taxes or other
additional costs incurred by such Lender which are not being incurred generally
by the other Lenders, (iii) delivered a notice pursuant to Section 4.3 claiming
that such Lender is unable to extend Eurodollar Rate Loans to any Borrower for
reasons not generally applicable to the other Lenders or (iv) has invoked
Section 11.2; then, in any such case, after engagement of one or more
"Replacement Lenders" (as defined below) by the Company and/or the
Administrative Agent, the Company or the Administrative Agent may make written
demand on such Affected Lender (with a copy to the Administrative Agent in the
case of a demand by the Company and a copy to the Company in the case of a
demand by the Administrative Agent) for the Affected Lender to assign, and such
Affected Lender shall use commercially reasonable efforts to assign pursuant to
one or more duly executed Assignment Agreements five (5) Business Days after the
date of such demand, to one or more financial institutions that comply with the
provisions of Section 14.3(A) which the Company or the Administrative Agent, as
the case may be, shall have engaged for such purpose ("REPLACEMENT LENDER"), all
of such Affected Lender's rights and obligations under this Agreement and the
other Loan Documents (including, without limitation, its Commitment, all Loans
owing to it, all of its participation interests in existing Letters of Credit,
L/C Drafts and unreimbursed drawings under Letters of Credit, and its obligation
to participate in additional Letters of Credit and Swing Line Loans hereunder)
in accordance with Section 14.3. The Administrative Agent agrees, upon the
occurrence of such events with respect to an Affected Lender and upon the
written request of the Company, to use its reasonable efforts to obtain the
commitments from one or more financial institutions to act as a Replacement
Lender. The Administrative Agent is authorized to execute one or more of such
assignment agreements as attorney-in-fact for any Affected Lender failing to
execute and deliver the same within five (5) Business Days after the date of
such demand. Further, with respect to such assignment the Affected Lender shall
have concurrently received, in cash, all amounts due and owing to the Affected
Lender hereunder or under any other Loan Document, including, without
limitation, the aggregate outstanding principal amount of the Loans owed to such
Lender, together with accrued interest thereon through the date of such
assignment, amounts payable under Sections 2.14(E), 4.1, and 4.2 with respect to
such Affected Lender and compensation payable under Section 2.14(C) in the event
of any replacement of any Affected Lender under clause (ii) or clause (iii) of
this Section 2.19; provided that upon such Affected Lender's replacement, such
Affected Lender shall cease to be a party hereto but shall continue to be
entitled to the benefits of Sections 2.14(E), 4.1, 4.2, 4.4, and 11.7, as well
as to any fees accrued for its account hereunder and not yet paid, and shall
continue to be obligated under Section 12.8.

       2.20.  Subsidiary Borrowers.  The Company may at any time or from time to
time, with the consent of the Administrative Agent add as a party to this
Agreement any Subsidiary to be a Subsidiary Borrower hereunder by the execution
and delivery to the Administrative Agent and the Lenders of (a) a duly completed
Assumption Letter by such Subsidiary, with the written consent of the Company at
the foot thereof, (b) such guaranty and subordinated intercompany indebtedness
documents as may be reasonably required by the Administrative Agent and such
other opinions, documents, certificates or other items as may be required by
Section 5.2, such documents with respect to any additional Subsidiaries to be
substantially similar in form and substance to the Loan Documents executed on or
about the date hereof by the Subsidiaries parties hereto as of the Closing Date.
Upon such execution, delivery and consent such

                                       44

<PAGE>   55

Subsidiary shall for all purposes be a party hereto as a Subsidiary Borrower as
fully as if it had executed and delivered this Agreement. So long as the
principal of and interest on any Advances made to any Subsidiary Borrower under
this Agreement shall have been repaid or paid in full, all Letters of Credit
issued for the account of such Subsidiary Borrower have expired or been returned
and terminated and all other obligations of such Subsidiary Borrower under this
Agreement shall have been fully performed, the Company may, by not less than
five (5) Business Days' prior notice to the Administrative Agent (which shall
promptly notify the Lenders thereof), terminate such Subsidiary Borrower's
status as a "Subsidiary Borrower". The Administrative Agent shall give the
Lenders written notice of the addition of any Subsidiary Borrowers to this
Agreement.

       2.21.  Judgment Currency. If, for the purposes of obtaining judgment in
any court, it is necessary to convert a sum due from any Borrower hereunder in
the currency expressed to be payable herein (the "specified currency") into
another currency, the parties hereto agree, to the fullest extent that they may
effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures the Administrative Agent could
purchase the specified currency with such other currency at the Administrative
Agent's main office in Chicago, Illinois on the Business Day preceding that on
which the final, non-appealable judgment is given. The obligations of each
Borrower in respect of any sum due to any Lender, any Issuing Bank or the
Administrative Agent hereunder shall, notwithstanding any judgment in a currency
other than the specified currency, be discharged only to the extent that on the
Business Day following receipt by such Lender, such Issuing Bank or the
Administrative Agent (as the case may be) of any sum adjudged to be so due in
such other currency such Lender, such Issuing Bank or the Administrative Agent
(as the case may be) may in accordance with normal, reasonable banking
procedures purchase the specified currency with such other currency. If the
amount of the specified currency so purchased is less than the sum originally
due to such Lender, such Issuing Bank or the Administrative Agent, as the case
may be, in the specified currency, each Borrower agrees, to the fullest extent
that it may effectively do so, as a separate obligation and notwithstanding any
such judgment, to reimburse such Lender, such Issuing Bank or the Administrative
Agent, as the case may be, for any such loss; and if no Default or Unmatured
Default shall have occurred and is continuing and the amount of the specified
currency so purchased exceeds (a) the sum originally due to any Lender, any
Issuing Bank or the Administrative Agent, as the case may be, in the specified
currency and (b) any amounts shared with other Lenders as a result of
allocations of such excess as a disproportionate payment to such Lender or
Issuing Bank under Section 14.2, such Lender, such Issuing Bank or the
Administrative Agent, as the case may be, agrees to remit such excess to such
Borrower.

                   ARTICLE III: THE LETTER OF CREDIT FACILITY

       3.1.   Obligation to Issue Letters of Credit. Subject to the terms and
conditions of this Agreement and in reliance upon the representations,
warranties and covenants of the Borrowers herein set forth, each Issuing Bank
hereby agrees to issue for the account of the Company or any Subsidiary Borrower
through such Issuing Bank's branches as it and the Company may jointly agree,
one or more Letters of Credit denominated in an Agreed Currency in accordance
with this

                                       45
<PAGE>   56

Article III, from time to time during the period, commencing on the Closing Date
and ending on the Business Day prior to the Termination Date.

       3.2.   Transitional Provision. Schedule 3.2 contains a schedule of
certain performance letters of credit and standby letters of credit issued for
the account of the Company and its Subsidiaries prior to the Closing Date.
Subject to the satisfaction of the conditions contained in Sections 5.1, 5.2 and
5.3, from and after the Closing Date such letters of credit shall be deemed to
be Letters of Credit issued pursuant to this Article III.

       3.3.   Types and Amounts.  No Issuing Bank shall have any obligation to
and no Issuing Bank shall:

              (i)    issue (or amend) any Letter of Credit if on the date of
       issuance (or amendment), before or after giving effect to the Letter of
       Credit requested hereunder, (a) the Dollar Amount of the Revolving Credit
       Obligations at such time would exceed the Aggregate Commitment at such
       time, or (b) the aggregate outstanding Dollar Amount of the L/C
       Obligations would exceed $100,000,000 (as such amount may be increased
       from time to time as provided in Section 2.5(C)), in each case,
       calculated as of the date of issuance of any Letter of Credit; or

              (ii)   issue (or amend) any Letter of Credit which has an
       expiration date later than the date which is the earlier of (x) one (1)
       year after the date of issuance thereof or (y) five (5) Business Days
       immediately preceding the Termination Date; provided, that any Letter of
       Credit with a one year tenor may provide for the renewal thereof for
       additional one year periods (which in no event shall extend beyond the
       date referred to in clause (y) above).

       3.4.   Conditions.  In addition to being subject to the satisfaction of
the conditions contained in Sections 5.1, 5.2 and 5.3, the obligation of an
Issuing Bank to issue any Letter of Credit is subject to the satisfaction in
full of the following conditions:

              (i)    the applicable Borrower shall have delivered to the
       applicable Issuing Bank (at such times and in such manner as such Issuing
       Bank may reasonably prescribe) and the Administrative Agent, a request
       for issuance of such Letter of Credit in substantially the form of
       Exhibit C hereto, duly executed applications for such Letter of Credit
       and such other documents, instructions and agreements as may be required
       pursuant to the terms thereof (all such applications, documents,
       instructions, and agreements being referred to herein as the "L/C
       DOCUMENTS"), and the proposed Letter of Credit shall be reasonably
       satisfactory to such Issuing Bank as to form and content; and

              (ii)   as of the date of issuance no order, judgment or decree of
       any court, arbitrator or Governmental Authority shall purport by its
       terms to enjoin or restrain the applicable Issuing Bank from issuing such
       Letter of Credit and no law, rule or regulation applicable to such
       Issuing Bank and no request or directive (whether or not having the force
       of law) from a Governmental Authority with jurisdiction over such Issuing
       Bank shall prohibit or request that such Issuing Bank refrain from the
       issuance of Letters of Credit generally or the issuance of that Letter of
       Credit.

                                       46
<PAGE>   57

       3.5.   Procedure for Issuance of Letters of Credit.

       (A)    Issuance. Subject to the terms and conditions of this Article III
and provided that the applicable conditions set forth in Sections 5.1, 5.2 and
5.3 hereof have been satisfied, the applicable Issuing Bank shall, on the
requested date, issue a Letter of Credit on behalf of the Company or a
Subsidiary Borrower, as applicable in accordance with such Issuing Bank's usual
and customary business practices and, in this connection, such Issuing Bank may
assume that the applicable conditions set forth in Section 5.3 hereof have been
satisfied unless it shall have received notice to the contrary from the
Administrative Agent or a Lender or has knowledge that the applicable conditions
have not been met. To the extent that there shall be any conflict between the
provisions of any L/C Document and the provisions of this Agreement, the
provisions of this Agreement shall prevail.

       (B)    Notice. The applicable Issuing Bank shall give the Administrative
Agent written or telex notice, or telephonic notice confirmed promptly
thereafter in writing, of the issuance of a Letter of Credit, provided, however,
that the failure to provide such notice shall not result in any liability on the
part of such Issuing Bank.

       (C)    No Amendment. No Issuing Bank shall extend or amend any Letter of
Credit unless the requirements of this Section 3.5 are met as though a new
Letter of Credit was being requested and issued.

       3.6.   Letter of Credit Participation. On the date of this Agreement,
with respect to the Letters of Credit identified on Schedule 3.2, and
immediately upon the issuance of each Letter of Credit hereunder, each Lender
shall be deemed to have automatically, irrevocably and unconditionally purchased
and received from the applicable Issuing Bank an undivided interest and
participation in and to such Letter of Credit, the obligations of the applicable
Borrower in respect thereof, and the liability of such Issuing Bank thereunder
(collectively, an "L/C INTEREST") in an amount equal to the Dollar Amount
available for drawing under such Letter of Credit multiplied by such Lender's
Pro Rata Share. Each Issuing Bank will notify the Administrative Agent and each
Lender promptly upon presentation to it of an L/C Draft or upon any other draw
under a Letter of Credit, which notice shall also state the Agreed Currency and
face amount of such L/C Draft or other draw. On or before the Business Day on
which an Issuing Bank makes payment of each such L/C Draft or, in the case of
any other draw on a Letter of Credit, on demand by the Administrative Agent or
the applicable Issuing Bank, each Lender shall make payment to the
Administrative Agent, for the account of the applicable Issuing Bank, in
immediately available funds in Dollars in an amount equal to such Lender's Pro
Rata Share of the Dollar Amount of such payment or draw. The obligation of each
Lender to reimburse the Issuing Banks under this Section 3.6 shall be
unconditional, continuing, irrevocable and absolute. In the event that any
Lender fails to make payment to the Administrative Agent of any amount due under
this Section 3.6, the Administrative Agent shall be entitled to receive, retain
and apply against such obligation the principal and interest otherwise payable
to such Lender hereunder until the Administrative Agent receives such payment
from such Lender or such obligation is otherwise fully satisfied; provided,
however, that nothing contained in this sentence shall relieve such Lender of
its obligation to reimburse the applicable Issuing Bank for such amount in
accordance with this Section 3.6.

                                       47
<PAGE>   58

       3.7.   Reimbursement Obligation. Each of the Borrowers agree
unconditionally, irrevocably and absolutely to pay immediately to the
Administrative Agent, for the account of the Lenders, the amount of each advance
drawn under or pursuant to a Letter of Credit issued to it or an L/C Draft
related thereto (such obligation of such Borrower to reimburse the
Administrative Agent for an advance made under a Letter of Credit or L/C Draft
being hereinafter referred to as a "REIMBURSEMENT OBLIGATION" with respect to
such Letter of Credit or L/C Draft), each such reimbursement to be made by the
applicable Borrower no later than the Business Day on which the applicable
Issuing Bank makes payment of each such L/C Draft or, if the applicable Borrower
shall have received notice of a Reimbursement Obligation later than 12:00 p.m.
(Chicago time), on any Business Day or on a day which is not a Business Day, no
later than 12:00 p.m. (Chicago time), on the immediately following Business Day
or, in the case of any other draw on a Letter of Credit, the date specified in
the demand of such Issuing Bank. If any Borrower at any time fails to repay a
Reimbursement Obligation at the time specified in the preceding sentence, such
unpaid Reimbursement Obligation shall at that time be automatically converted
into an obligation denominated in Dollars and such Borrower shall be deemed to
have elected to borrow Revolving Loans from the Lenders, as of the date of the
advance giving rise to the Reimbursement Obligation, equal in amount to the
Dollar Amount of the unpaid Reimbursement Obligation. Such Revolving Loans shall
be made as of the date of the payment giving rise to such Reimbursement
Obligation, automatically, without notice and without any requirement to satisfy
the conditions precedent otherwise applicable to an Advance of Revolving Loans.
Such Revolving Loans shall constitute a Floating Rate Advance, the proceeds of
which Advance shall be used to repay such Reimbursement Obligation. If, for any
reason, any Borrower fails to repay a Reimbursement Obligation on the day such
Reimbursement Obligation arises and, for any reason, the Lenders are unable to
make or have no obligation to make Revolving Loans, then such Reimbursement
Obligation shall bear interest from and after such day, until paid in full, at
the interest rate applicable to a Floating Rate Advance (or, in the case of a
Reimbursement Obligation denominated in an Agreed Currency other than Dollars,
at the rate determined by the applicable Issuing Bank in good faith to represent
such Issuing Bank's cost of overnight or short-term funds in the applicable
Agreed Currency plus the then effective Applicable Eurodollar Margin). The
Borrowers agree to indemnify each Issuing Bank against any loss or expense
determined by such Issuing Bank in good faith to have resulted from any
conversion pursuant to this Section 3.7 by reason of the inability of such
Issuing Bank to convert the Dollar Amount received from the applicable Borrower
or from the Lenders, as applicable, into an amount in the applicable Agreed
Currency of such Letter of Credit equal to the amount of such Reimbursement
Obligation.

       3.8.   Letter of Credit Fees.  The Borrowers agree to pay:

              (i)    quarterly, in arrears, to the Administrative Agent for the
       ratable benefit of the Lenders, a letter of credit fee at a rate per
       annum equal to the Applicable L/C Fee Percentage for Performance Letters
       of Credit and Standby Letters of Credit, as applicable, on the average
       daily outstanding Dollar Amount available for drawing under all
       Performance Letters of Credit and Standby Letters of Credit,
       respectively;

                                       48

<PAGE>   59

              (ii)   quarterly, in arrears, to the applicable Issuing Bank, a
       letter of credit fronting fee equal to 0.125% per annum on the average
       daily outstanding stated amount available for drawing under all Letters
       of Credit issued by such Issuing Bank; and

              (iii)  to the applicable Issuing Bank, all customary fees and
       other issuance, amendment, cancellation, document examination,
       negotiation, transfer and presentment expenses and related charges in
       connection with the issuance, amendment, cancellation, presentation of
       L/C Drafts, negotiation, transfer and the like customarily charged by
       such Issuing Banks with respect to standby, performance and commercial
       letters of credit, including, without limitation, standard commissions
       with respect to Performance Letters of Credit, payable at the time of
       invoice of such amounts.

       3.9.   Borrower and Issuing Bank Reporting Requirements. The Company
shall, at any time as requested by the Administrative Agent or the Required
Lenders but in any event no later than the tenth Business Day following the last
day of each month, provide to the Administrative Agent schedules, in form and
substance reasonably satisfactory to the Administrative Agent, showing the date
of issue, account party, Agreed Currency and amount in such Agreed Currency,
Issuing Bank, expiration date and the reference number of each Letter of Credit
issued hereunder outstanding at any time during such month. In addition to the
notices required by Section 3.5(B), each Issuing Bank shall, at any time as
requested by the Administrative Agent or the Required Lenders but in any event
no later than the tenth Business Day following the last day of each month,
provide to the Administrative Agent schedules, in form and substance reasonably
satisfactory to the Administrative Agent, showing the date of issue, account
party, Agreed Currency and amount in such Agreed Currency, expiration date and
the reference number of each Letter of Credit issued by it outstanding at any
time during such month and the aggregate amount payable by the applicable
Borrower during such month. In addition, upon the request of the Administrative
Agent, each Issuing Bank shall furnish to the Administrative Agent copies of any
Letter of Credit and any application for or reimbursement agreement with respect
to a Letter of Credit to which the Issuing Bank is party and such other
documentation as may reasonably be requested by the Administrative Agent. Upon
the request of any Lender, the Administrative Agent will provide to such Lender
information concerning such Letters of Credit as the Administrative Agent has
received from the Issuing Banks.

       3.10.  Indemnification; Exoneration.

       (A)    Indemnification. In addition to amounts payable as elsewhere
provided in this Article III, each Borrower hereby agrees to protect, indemnify,
pay and save harmless the Administrative Agent, each Issuing Bank and each
Lender from and against any and all liabilities and costs which the
Administrative Agent, such Issuing Bank or such Lender may incur or be subject
to in any way directly connected with (i) the issuance of any Letter of Credit
other than, in the case of the applicable Issuing Bank, as a result of its Gross
Negligence or willful misconduct, as determined by the final judgment of a court
of competent jurisdiction, or (ii) the failure of the applicable Issuing Bank to
honor a drawing under a Letter of Credit as a result of any act or omission,
whether rightful or wrongful, of any present or future de jure or de facto
Governmental Authority (all such acts or omissions herein called "GOVERNMENTAL
ACTS").

                                       49

<PAGE>   60

       (B)    Risk Assumption. As among the Borrowers, the Lenders, the
Administrative Agent and the Issuing Banks, the Borrowers assume all risks of
the acts and omissions of, or misuse of such Letter of Credit by, the
beneficiary of any Letters of Credit. In furtherance and not in limitation of
the foregoing, subject to the provisions of the Letter of Credit applications
and Letter of Credit reimbursement agreements executed by the Borrowers at the
time of request for any Letter of Credit, neither the Administrative Agent, any
Issuing Bank nor any Lender shall be responsible (in the absence of Gross
Negligence or willful misconduct in connection therewith, as determined by the
final judgment of a court of competent jurisdiction): (i) for the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for and issuance of
the Letters of Credit, even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason; (iii) for failure of the beneficiary of a
Letter of Credit to comply duly with conditions required in order to draw upon
such Letter of Credit; (iv) for errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telex, or
other similar form of teletransmission or otherwise; (v) for errors in
interpretation of technical trade terms; (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any Letter of Credit or of the proceeds thereof; (vii) for the
misapplication by the beneficiary of a Letter of Credit of the proceeds of any
drawing under such Letter of Credit; and (viii) for any consequences arising
from causes beyond the control of the Administrative Agent, the Issuing Banks
and the Lenders, including, without limitation, any Governmental Acts. None of
the above shall affect, impair, or prevent the vesting of any Issuing Bank's
rights or powers under this Section 3.10.

       (C)    No Liability. In furtherance and extension and not in limitation
of the specific provisions hereinabove set forth, any action taken or omitted by
any Issuing Bank under or in connection with the Letters of Credit or any
related certificates shall not, in the absence of Gross Negligence or willful
misconduct, as determined by the final judgment of a court of competent
jurisdiction, put the applicable Issuing Bank, the Administrative Agent or any
Lender under any resulting liability to any Borrower or relieve any Borrower of
any of its obligations hereunder to any such Person.

       (D)    Survival of Agreements and Obligations. Without prejudice to the
survival of any other agreement of the Borrowers hereunder, the agreements and
obligations of the Borrowers contained in this Section 3.10 shall survive the
payment in full of principal and interest hereunder, the termination of the
Letters of Credit and the termination of this Agreement.

       3.11.  Market Disruption. Notwithstanding the satisfaction of all
conditions referred to in Article II, Article III and Article V with respect to
any Letter of Credit to be issued in any Agreed Currency other than Dollars, if
there shall occur on or prior to the date of issuance of such Letter of Credit
any Market Disruption, then the Administrative Agent shall forthwith give notice
thereof to the Borrowers, the Issuing Bank and the Lenders, and such Letter of
Credit shall not be denominated in such Agreed Currency but shall be made on the
date of issuance of such Letter of Credit in Dollars, in a face amount equal to
the Dollar Amount of the face amount

                                       50

<PAGE>   61

specified in the related request or application for such Letter of Credit,
unless the Borrower notifies the Administrative Agent at least one Business Day
before such date that (i) it elects not to request the issuance of such Letter
of Credit on such date or (ii) it elects to have such Letter of Credit issued on
such date in a different Agreed Currency, as the case may be, in which the
denomination of such Letter of Credit would in the opinion of the applicable
Issuing Bank, the Administrative Agent and the Required Lenders be practicable
and in a face amount equal to the Dollar Amount of the face amount specified in
the related request or application for such Letter of Credit, as the case may
be.

                       ARTICLE IV: CHANGE IN CIRCUMSTANCES

       4.1.   Yield Protection.

       (A)    Yield Protection. If any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law) adopted after the date of this Agreement and having
general applicability to all banks within the jurisdiction in which such Lender
operates (excluding, for the avoidance of doubt, the effect of and phasing in of
capital requirements or other regulations or guidelines passed prior to the date
of this Agreement), or any interpretation or application thereof by any
Governmental Authority charged with the interpretation or application thereof,
or the compliance of any Lender therewith,

              (i)    subjects any Lender or any applicable Lending Installation
       to any tax, duty, charge or withholding on or from payments due from any
       Borrower (excluding taxation of the overall net income of any Lender or
       taxation of a similar basis, which are governed by Section 2.14(E)), or
       changes the basis of taxation of payments to any Lender in respect of its
       Commitment, Loans, its L/C Interests, the Letters of Credit or other
       amounts due it hereunder, or

              (ii)   imposes or increases or deems applicable any reserve,
       assessment, insurance charge, special deposit or similar requirement
       against assets of, deposits with or for the account of, or credit
       extended by, any Lender or any applicable Lending Installation (other
       than reserves and assessments taken into account in determining the
       interest rate applicable to Eurodollar Rate Loans) with respect to its
       Commitment, Loans, L/C Interests, Loans or the Letters of Credit, or

              (iii)  imposes any other condition the result of which is to
       increase the cost to any Lender or any applicable Lending Installation of
       making, funding or maintaining its Commitment, the Loans, the L/C
       Interests or the Letters of Credit or reduces any amount receivable by
       any Lender or any applicable Lending Installation in connection with its
       Commitment, Loans or Letters of Credit, or requires any Lender or any
       applicable Lending Installation to make any payment calculated by
       reference to the amount of Commitment, Loans or L/C Interests held or
       interest received by it or by reference to the Letters of Credit, by an
       amount deemed material by such Lender;

and the result of any of the foregoing is to increase the cost to that Lender of
making, renewing or maintaining its Commitment, Loans, L/C Interests, or Letters
of Credit or to reduce any

                                       51

<PAGE>   62

amount received under this Agreement, then, within fifteen (15) days after
receipt by the Company or any other Borrower of written demand by such Lender
pursuant to Section 4.5, the applicable Borrowers shall pay such Lender that
portion of such increased expense incurred or reduction in an amount received
which such Lender determines is attributable to making, funding and maintaining
its Loans, L/C Interests, Letters of Credit and its Commitment.

       (B)    Non-U.S. Reserve Costs or Fees With Respect to Loans and Letters
of Credit to Borrowers. If any law or any governmental or quasi-governmental
rule, regulation, policy, guideline or directive of any jurisdiction outside of
the United States of America or any subdivision thereof (whether or not having
the force of law), imposes or deems applicable any reserve requirement against
or fee with respect to assets of, deposits with or for the account of, or credit
extended by, any Lender, any Issuing Bank or any applicable Lending
Installation, and the result of the foregoing is to increase the cost to such
Lender, such Issuing Bank or applicable Lending Installation of making or
maintaining its Eurodollar Loans to, or issuing a Letter of Credit in an Agreed
Currency other than Dollars for the benefit of, any Borrower or its Commitment
to any Borrower or to reduce the return received by such Lender, such Issuing
Bank or applicable Lending Installation in connection with such Eurodollar Loans
or Letters of Credit to or for the benefit of any Borrower or Commitment to any
Borrower, then, within 15 days of demand by such Lender or such Issuing Bank,
such Borrower shall pay such Lender or such Issuing Bank, as applicable, such
additional amount or amounts as will compensate such Lender or such Issuing Bank
for such increased cost or reduction in amount received, provided that such
Borrower shall not be required to compensate any Lender for such non-U.S.
reserve costs or fees to the extent that an amount equal to such reserve costs
or fees is received by such Lender as a result of the calculation of the
interest rate applicable to Eurodollar Rate Advances pursuant to clause (i)(b)
of the definition of "Eurodollar Rate."

       4.2.   Changes in Capital Adequacy Regulations. If a Lender determines
(i) the amount of capital required or expected to be maintained by such Lender,
any Lending Installation of such Lender or any corporation controlling such
Lender is increased as a result of a "Change" (as defined below), and (ii) such
increase in capital will result in an increase in the cost to such Lender of
maintaining its Commitment, Loans, L/C Interests, the Letters of Credit or its
obligation to make Loans hereunder, then, within fifteen (15) days after receipt
by the Company or any other Borrower of written demand by such Lender pursuant
to Section 4.5, the applicable Borrowers shall pay such Lender the amount
necessary to compensate for any shortfall in the rate of return on the portion
of such increased capital which such Lender determines is attributable to this
Agreement, its Commitment, its Loans, its L/C Interests, the Letters of Credit
or its obligation to make Loans hereunder (after taking into account such
Lender's policies as to capital adequacy). "CHANGE" means (i) any change after
the date of this Agreement in the "Risk-Based Capital Guidelines" (as defined
below) excluding, for the avoidance of doubt, the effect of any phasing in of
such risk-based capital guidelines or any other capital requirements passed
prior to the date hereof, or (ii) any adoption of or change in any other law,
governmental or quasi-governmental rule, regulation, policy, guideline,
interpretation, or directive (whether or not having the force of law) after the
date of this Agreement which affects the amount of capital required or expected
to be maintained by any Lender or any Lending Installation or any corporation
controlling any Lender. "RISK-BASED CAPITAL GUIDELINES" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including

                                       52

<PAGE>   63

transition rules, and (ii) the corresponding capital regulations promulgated by
regulatory authorities outside the United States implementing the July 1988
report of the Basle Committee on Banking Regulation and Supervisory Practices
Entitled "International Convergence of Capital Measurements and Capital
Standards," including transition rules, and any amendments to such regulations
adopted prior to the date of this Agreement.

       4.3.   Availability of Types of Advances. If (i) any Lender determines
that maintenance of its Eurodollar Rate Loans at a suitable Lending Installation
would violate any applicable law, rule, regulation or directive, whether or not
having the force of law, or (ii) the Required Lenders determine that (x)
deposits of a type or maturity appropriate to match fund Eurodollar Rate Loans
are not available or (y) the interest rate applicable to a Eurodollar Rate Loan
does not accurately reflect the cost of making or maintaining such an Advance,
then the Administrative Agent shall suspend the availability of the affected
Type of Advance and, in the case of any occurrence set forth in clause (i),
require any Advances of the affected Type to be repaid or converted into another
Type.

       4.4.   Funding Indemnification. If any payment of a Eurodollar Rate Loan
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment (whether voluntary or mandatory,
including, without limitation as required pursuant to Section 2.4(B)), or
otherwise (including, without limitation, as a result of the provisions of
Section 2.5(B)), or a Eurodollar Rate Loan is not made on the date specified by
the applicable Borrower for any reason other than default by the Lenders, or a
Eurodollar Rate Loan is not prepaid on the date specified by the applicable
Borrower for any reason, the Borrowers indemnify each Lender for any loss or
cost incurred by it resulting therefrom, including, without limitation, any loss
or cost in liquidating or employing deposits acquired to fund or maintain the
Eurodollar Rate Loan.

       4.5.   Lender Statements; Survival of Indemnity. If reasonably possible,
each Lender shall designate an alternate Lending Installation with respect to
its Eurodollar Rate Loan to reduce any liability of any Borrower to such Lender
under Sections 4.1 and 4.2 or to avoid the unavailability of a Type of Advance
under Section 4.3, so long as such designation is not, in the judgment of the
Lender, disadvantageous to such Lender. Each Lender shall deliver a written
statement of such Lender to the Company (with a copy to the Administrative
Agent) as to the amount due, if any, under Section 2.14(E), 4.1, 4.2 or 4.4 and
shall set forth in reasonable detail the calculations upon which such Lender
determined such amount and shall be prima facie evidence thereof and binding on
the Borrowers in the absence of manifest error. Determination of amounts payable
under such Sections in connection with a Eurodollar Rate Loan shall be
calculated as though each Lender funded its Eurodollar Rate Loan through the
purchase of a deposit of the type and maturity corresponding to the deposit used
as a reference in determining the Eurodollar Rate applicable to such Loan,
whether in fact that is the case or not. Unless otherwise provided herein, the
amount specified in the written statement of any Lender shall be payable on
demand after receipt by the applicable Borrower of such statement. The
obligations of the Company and the other Borrowers under Sections 2.14(E), 4.1,
4.2 and 4.4 shall survive payment of the Obligations and termination of this
Agreement.

       5.2.   Initial Advance to Each New Subsidiary Borrower. No Lender shall
be required to make an Advance hereunder or purchase participations in Letters
of Credit, no Issuing Bank shall be required to issue a Letter of Credit
hereunder, in each case, to a new Subsidiary Borrower added after the Closing
Date unless the Company has furnished or caused to be furnished to the

<PAGE>   66

              other jurisdiction where filings are required in order for
              amounts payable under this Agreement to be exempt from applicable
              withholding or other taxes), the Administrative Agent shall have
              received originals and/or copies, as applicable, of all filings
              required to be made and such other evidence as the Administrative
              Agent may require establishing to the Administrative Agent's
              satisfaction that each Lender, Swing Line Bank and Issuing Bank
              is entitled to receive payments under the Loan Documents without
              deduction or withholding of any English (or other applicable
              jurisdictions) taxes or with such deductions and withholding of
              English (or other applicable jurisdictions) taxes as may be
              acceptable to the Administrative Agent.

       5.3.   Each Advance and Letter of Credit. The Lenders shall not be
required to make any Advance, or convert or continue any Advance, or issue any
Letter of Credit and no Swing Line Bank shall be required to make any Swing Line
Loans hereunder, unless on the applicable Borrowing Date, or in the case of a

       (A)    No Defaults. There exists no Default or Unmatured Default (other
than any Unmatured Default that may be deemed to have occurred as of such date
as a result of the failure of the H-B Acquisition to close on or before December
31, 2000);

       (B)    Representations and Warranties. All of the representations and
warranties contained in Article VI are true and correct as of such Borrowing
Date (unless such representation and warranty is made as of a specific date, in
which case, such representation and warranty shall be true and correct as of
such date) except for changes in the Schedules to this Agreement reflecting
transactions permitted by or not in violation of this Agreement; and

       (C)    Maximum Amounts. The Revolving Credit Obligations do not, and
after making such proposed Advance or issuing such Letter of Credit would not,
exceed the Aggregate Commitment.

       Each Borrowing/Election Notice with respect to each such Advance and the
letter of credit application with respect to each Letter of Credit shall
constitute a representation and warranty by the Borrowers that the conditions
contained in Sections 5.3(A), (B) and (C) have been satisfied. Any Lender may
require a duly completed officer's certificate in substantially the form of
Exhibit G hereto and/or a duly completed compliance certificate in substantially
the form of Exhibit H hereto as a condition to making an Advance.

                   ARTICLE VI: REPRESENTATIONS AND WARRANTIES

              In order to induce the Administrative Agent and the Lenders to
enter into this Agreement and to make the Loans and the other financial

Administrative Agent as of the Closing Date, giving effect to the consummation
of the transactions contemplated by the Transaction Documents on the Closing
Date, and thereafter on each date as required by Section 5.2 and 5.3:

       6.1. Organization; Corporate Powers. The Company and each of its
Subsidiaries (i) is a corporation, limited liability company, partnership duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, (ii) is duly qualified to do business as a

business as presently conducted and as proposed to be conducted

       6.2.   Authority, Execution and Delivery; Transaction Documents.

and authority to execute, deliver and perform each of the Transaction Documents
which are to be executed by it as required by this Agreement and the other
Transaction Documents and (ii) to file the Transaction Documents which must be
filed by it as required by this Agreement, the other Loan Documents or otherwise
with any Governmental Authority.

       (B) Execution and Delivery. The execution, delivery, performance and
filing, as the case may be, of each of the Transaction Documents as required by
this Agreement or otherwise and to which any Loan Party is party, and the
consummation of the transactions contemplated thereby, have been duly approved
by the respective boards of directors and, if necessary, the shareholders of the
applicable Loan Parties, and such approvals have not been rescinded.

       (C) Transaction Documents. Each of the Transaction Documents to which the
Company or any of its Subsidiaries is a party has been duly executed, delivered
or filed, as the case may be, by it and constitutes its legal, valid and binding
obligation, enforceable against it in accordance with its terms (except as
enforceability may be limited by bankruptcy, insolvency, or similar laws
affecting the enforcement of creditors' rights generally), is in full force and
effect and no material term or condition thereof has been amended, modified or
waived from the terms and conditions contained in the Transaction Documents
delivered to the Administrative Agent pursuant to Section 5.1 without the prior
written consent of the Administrative Agent, and the Company and its
Subsidiaries have, and, to the best of the Company's and its Subsidiaries'
knowledge, all other parties thereto have, performed and complied with all the
terms, provisions, agreements and conditions set forth therein and required to
be performed or complied with by such parties, and no unmatured default, default
or breach of any covenant by any such party exists thereunder.

       6.3. No Conflict; Governmental Consents. The execution, delivery and
performance of each of the Transaction Documents to which each of the Loan
Parties is a party do not and will not (i) conflict with the certificate or
articles of incorporation or by-laws of such Loan Party, (ii) constitute a
tortious interference with any Contractual Obligation of any Person or conflict
with, result in a breach of or constitute (with or without notice or lapse of
time or both) a default under any Requirement of Law or Contractual Obligation
of any such Loan Party, or require termination of any Contractual Obligation,
(iii) result in or require the creation or imposition of any Lien whatsoever
upon any of the property or assets of the Company or any of its Subsidiaries,

except such as have been

                                       57
<PAGE>   68

obtained. The execution, delivery and performance of each of the Transaction
Documents to which the Company or any of its Subsidiaries is a party do not and
will not require any registration with, consent or approval of, or notice to, or
other action to, with or by any Governmental Authority, except filings, consents
or notices which have been made, obtained or given, or which, if not made,
obtained or given, individually or in the aggregate could not reasonably be
expected to have a Material Adverse Effect.

       6.4.   Financial Statements.

       (A) Pro Forma Financials. The combined pro forma balance sheet, income
statements and statements of cash flow of the Company and its Subsidiaries
(after giving effect to the H-B Acquisition), copies of which are attached
hereto as Schedule 6.4 to this Agreement, present on a pro forma basis the
financial condition of the Company and such Subsidiaries as of such date, and
demonstrate that the Company and its Subsidiaries can repay their debts and
satisfy their other obligations as and when due, and can comply with the
requirements of this Agreement. The projections and assumptions expressed in the
pro forma financials referenced in this Section 6.4(A) were prepared in good
faith and represent management's opinion based on the information available to
the Company at the time so furnished and, since the preparation thereof and up
to the Closing Date, there has occurred no change in the business, financial
condition, operations, or prospects of the Company or any of its Subsidiaries,
or the Company and its Subsidiaries taken as a whole, or Howe-Baker or
Howe-Baker and its Subsidiaries taken as a whole which has had or could
reasonably be expected to have a Material Adverse Effect.

       (B) Audited Financial Statements. Complete and accurate copies of the
audited financial statements and the audit reports related thereto of (i) the
Company and its consolidated Subsidiaries as at December 31, 1999 and (ii)
Howe-Baker and its consolidated Subsidiaries as of December 31, 1999, have been
delivered to the Administrative Agent and such financial statements were
prepared in accordance with generally accepted accounting principles in effect
on the date such statements were prepared and fairly present the consolidated
financial condition and operations of the Company and its Subsidiaries and
Howe-Baker and its Subsidiaries, respectively, at such date and the consolidated
results of their operations for the period then ended.

       (C) Interim Financial Statements. Complete and accurate copies of the
unaudited financial statements of (i) the Company and its consolidated
Subsidiaries as at June 30, 2000 and (ii) Howe-Baker and its consolidated
Subsidiaries as at June 30, 2000, have been delivered to the Administrative
Agent and such financial statements were prepared in accordance with generally
accepted accounting principles in effect on the date such statements were
prepared and fairly present the consolidated financial condition and operations
of the Company and its Subsidiaries and Howe-Baker and its Subsidiaries,
respectively, at such date and the consolidated results of their operations for
the period then ended, subject to normal year-end audit adjustments.

       6.5.   No Material Adverse Change. Since December 31, 1999, there has
occurred no change in the business, properties, condition (financial or
otherwise), performance, results of operations or prospects of the Company, any
other Borrower, the Company and its Subsidiaries

                                       58
<PAGE>   69
taken as a whole, Howe-Baker or Howe-Baker and its Subsidiaries taken as a whole
or any other event which has had or could reasonably be expected to have a
Material Adverse Effect.

       6.6.   Taxes.

       (A) Tax Examinations. All deficiencies which have been asserted against
the Company or any of the Company's Subsidiaries as a result of any federal,
state, local or foreign tax examination for each taxable year in respect of
which an examination has been conducted have been fully paid or finally settled
or are being contested in good faith, and no issue has been raised by any taxing
authority in any such examination which, by application of similar principles,
could reasonably be expected to result in assertion by such taxing authority of
a material deficiency for any other year not so examined which has not been
reserved for in the Company's consolidated financial statements to the extent,
if any, required by Agreement Accounting Principles. Except as permitted
pursuant to Section 7.2(D), neither the Company nor any of the Company's
Subsidiaries anticipates any tax liability with respect to the years which have
not been closed pursuant to applicable law.

       (B) Payment of Taxes. All material tax returns and reports of the Company
and its Subsidiaries required to be filed have been timely filed, and all taxes,
assessments, fees and other governmental charges thereupon and upon their
respective property, assets, income and franchises which are shown in such
returns or reports to be due and payable have been paid except those items which
are being contested in good faith and have been reserved for in accordance with
Agreement Accounting Principles. The Company has no knowledge of any proposed
tax assessment against it or any of its Subsidiaries that will have or could
reasonably be expected to have a Material Adverse Effect.

       6.7. Litigation; Loss Contingencies and Violations. There is no action,
suit, proceeding, arbitration or, to the Company's knowledge, investigation
before or by any Governmental Authority or private arbitrator pending or, to the
Company's knowledge, threatened against or affecting the Company or any of its
Subsidiaries or any property of any of them, including, without limitation, any
such actions, suits, proceedings, arbitrations and investigations disclosed in
the Company's SEC Forms 10-K and 10-Q (the "DISCLOSED LITIGATION"), which (i)
challenges the validity or the enforceability of any material provision of the
Transaction Documents or (ii) has or could reasonably be expected to have a
Material Adverse Effect. There is no material loss contingency within the
meaning of Agreement Accounting Principles which has not been reflected in the
consolidated financial statements of the Company prepared and delivered pursuant
to Section 7.1(A) for the fiscal period during which such material loss
contingency was incurred. Neither the Company nor any of its Subsidiaries is (A)
in violation of any applicable Requirements of Law which violation could
reasonably be expected to have a Material Adverse Effect, or (B) subject to or
in default with respect to any final judgment, writ, injunction, restraining
order or order of any nature, decree, rule or regulation of any court or
Governmental Authority which could reasonably be expected to have a Material
Adverse Effect.

       6.8.   Subsidiaries. Schedule 6.8 to this Agreement (i) contains a
description of the corporate structure of the Company, its Subsidiaries and any
other Person in which the Company

                                       59
<PAGE>   70
or any of its Subsidiaries holds an Equity Interest; and (ii) accurately sets
forth (A) the correct legal name, the jurisdiction of incorporation and the
jurisdictions in which each of the Company and the direct and indirect
Subsidiaries of the Company are qualified to transact business as a foreign
corporation, (B) the authorized, issued and outstanding shares of each class of
Capital Stock of each of the Company's Foreign Subsidiaries and the owners of
such shares (both as of the Closing Date and on a fully-diluted basis), and (C)
a summary of the direct and indirect partnership, joint venture, or other Equity
Interests, if any, of the Company and each of its Subsidiaries in any Person.
Except as disclosed on Schedule 6.8, none of the issued and outstanding Capital
Stock of the Company's Foreign Subsidiaries is subject to any vesting,
redemption, or repurchase agreement, and there are no warrants or options
outstanding with respect to such Capital Stock. The outstanding Capital Stock of
each of the Company's Subsidiaries is duly authorized, validly issued, fully
paid and nonassessable and is not Margin Stock.

       6.9. ERISA. No Benefit Plan has incurred any material accumulated funding
deficiency (as defined in Sections 302(a)(2) of ERISA and 412(a) of the Code)
whether or not waived. Neither the Company nor any member of the Controlled
Group has incurred any material liability to the PBGC which remains outstanding
other than the payment of premiums. As of the last day of the most recent prior
plan year, the market value of assets under each Benefit Plan, other than any
Multiemployer Plan, was not by a material amount less than the present value of
benefit liabilities thereunder (determined in accordance with the actuarial
valuation assumptions described therein). Neither the Company nor any member of
the Controlled Group has (i) failed to make a required contribution or payment
to a Multiemployer Plan of a material amount or (ii) incurred a material
complete or partial withdrawal under Section 4203 or Section 4205 of ERISA from
a Multiemployer Plan. Neither the Company nor any member of the Controlled Group
has failed to make an installment or any other payment of a material amount
required under Section 412 of the Code on or before the due date for such
installment or other payment. Each Plan, Foreign Employee Benefit Plan and
Non-ERISA Commitment complies in all material respects in form, and has been
administered in all material respects in accordance with its terms and in
accordance with all applicable laws and regulations, including but not limited
to ERISA and the Code. There have been no and there is no prohibited transaction
described in Sections 406 of ERISA or 4975 of the Code with respect to any Plan
for which a statutory or administrative exemption does not exist which could
reasonably be expected to subject the Company or any of is Subsidiaries to
material liability. Neither the Company nor any member of the Controlled Group
has taken or failed to take any action which would constitute or result in a
Termination Event, which action or inaction could reasonably be expected to
subject the Company or any of its Subsidiaries to material liability. Neither
the Company nor any member of the Controlled Group is subject to any material
liability under, or has any potential material liability under, Section 4063,
4064, 4069, 4204 or 4212(c) of ERISA. The present value of the aggregate
liabilities to provide all of the accrued benefits under any Foreign Pension
Plan do not exceed the current fair market value of the assets held in trust or
other funding vehicle for such plan by a material amount. With respect to any
Foreign Employee Benefit Plan other than a Foreign Pension Plan, reasonable
reserves have been established in accordance with prudent business practice or
where required by ordinary accounting practices in the jurisdiction in which
such plan is maintained. Neither the Company nor any other member of the
Controlled Group has taken or failed to take any action, nor has any event
occurred, with

                                       60
<PAGE>   71
respect to any "employee benefit plan" (as defined in Section 3(3) of ERISA)
which action, inaction or event could reasonably be expected to subject the
Company or any of its Subsidiaries to material liability. For purposes of this
Section 6.9, "material" means any amount, noncompliance or other basis for
liability which could reasonably be expected to subject the Company or any of
its Subsidiaries to liability, individually or in the aggregate with each other
basis for liability under this Section 6.9, in excess of $2,000,000.

       6.10. Accuracy of Information. The information, exhibits and reports
furnished by or on behalf of the Company and any of its Subsidiaries to the
Administrative Agent or to any Lender in connection with the negotiation of, or
compliance with, the Transaction Documents, the representations and warranties
of the Company and its Subsidiaries contained in the Transaction Documents, and
all certificates and documents delivered to the Administrative Agent and the
Lenders pursuant to the terms thereof, taken as a whole, do not contain as of
the date furnished any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements contained herein or
therein, in light of the circumstances under which they were made, not
misleading.

       6.11. Securities Activities. Neither the Company nor any of its
Subsidiaries is engaged principally, or as one of its important activities, in
the business of extending credit for the purpose of purchasing or carrying
Margin Stock. Margin Stock constitutes less than 25% of the value of those
assets of the Company and its Subsidiaries which are subject to any limitation
on sale, pledge, or other restriction hereunder.

       6.12. Material Agreements. Neither the Company nor any of its
Subsidiaries is a party to any Contractual Obligation or subject to any charter
or other corporate restriction which individually or in the aggregate has had or
could reasonably be expected to have a Material Adverse Effect. Neither the
Company nor any of its Subsidiaries has received notice or has knowledge that
(i) it is in default in the performance, observance or fulfillment of any of the
obligations, covenants or conditions contained in any Contractual Obligation
applicable to it, or (ii) any condition exists which, with the giving of notice
or the lapse of time or both, would constitute a default with respect to any
such Contractual Obligation, in each case, except where such default or
defaults, if any, individually or in the aggregate could not reasonably be
expected to have a Material Adverse Effect.

       6.13. Compliance with Laws. The Company and its Subsidiaries are in
compliance with all Requirements of Law applicable to them and their respective
businesses, in each case where the failure to so comply individually or in the
aggregate could reasonably be expected to have a Material Adverse Effect.

       6.14. Assets and Properties. The Company and each of its Subsidiaries has
good and marketable title to all of its material assets and properties (tangible
and intangible, real or personal) owned by it or a valid leasehold interest in
all of its material leased assets (except insofar as marketability may be
limited by any laws or regulations of any Governmental Authority affecting such
assets), and all such assets and property are free and clear of all Liens,
except Liens permitted under Section 7.3(C). Substantially all of the assets and
properties owned by, leased to or used by the Company and/or each such
Subsidiary of the Company are in

                                       61
<PAGE>   72
adequate operating condition and repair, ordinary wear and tear excepted.
Neither this Agreement nor any other Transaction Document, nor any transaction
contemplated under any such agreement, will affect any right, title or interest
of the Company or such Subsidiary in and to any of such assets in a manner that
could reasonably be expected to have a Material Adverse Effect.

       6.15. Statutory Indebtedness Restrictions. Neither the Company nor any of
its Subsidiaries is subject to regulation under the Public Utility Holding
Company Act of 1935, the Federal Power Act, the Investment Company Act of 1940,
or any other foreign, federal or state statute or regulation which limits its
ability to incur indebtedness or its ability to consummate the transactions
contemplated hereby.

       6.16.   Insurance. The insurance policies and programs in effect with
respect to the respective properties, assets, liabilities and business of the
Company and its Subsidiaries reflect coverage that is reasonably consistent with
prudent industry practice.

       6.17.  Environmental Matters.

       (A)    Environmental Representations. Except as disclosed on Schedule
6.17 to this Agreement:

               (i) the operations of the Company and its Subsidiaries comply in
       all material respects with Environmental, Health or Safety Requirements
       of Law;

               (ii) the Company and its Subsidiaries have all material permits,
       licenses or other authorizations required under Environmental, Health or
       Safety Requirements of Law and are in material compliance with such
       permits;

               (iii) neither the Company, any of its Subsidiaries nor any of
       their respective present property or operations, or, to the Company's or
       any of its Subsidiaries' knowledge, any of their respective past property
       or operations, are subject to or the subject of, any investigation known
       to the Company or any of its Subsidiaries, any judicial or administrative
       proceeding, order, judgment, decree, settlement or other agreement
       respecting: (A) any material violation of Environmental, Health or Safety
       Requirements of Law; (B) any remedial action; or (C) any material claims
       or liabilities arising from the Release or threatened Release of a
       Contaminant into the environment;

               (iv) there is not now, nor to the Company's or any of its
       Subsidiaries' knowledge has there ever been, on or in the property of the
       Company or any of its Subsidiaries any landfill, waste pile, underground
       storage tanks, aboveground storage tanks, surface impoundment or
       hazardous waste storage facility of any kind, any polychlorinated
       biphenyls (PCBs) used in hydraulic oils, electric transformers or other
       equipment, or any asbestos containing material; and

               (v) neither the Company nor any of its Subsidiaries has any
       material Contingent Obligation in connection with any Release or
       threatened Release of a Contaminant into the environment.

                                       62
<PAGE>   73
       (B) Materiality. For purposes of this Section 6.17 "material" means any
noncompliance or basis for liability which could reasonably be likely to subject
the Company or any of its Subsidiaries to liability, individually or in the
aggregate, in excess of $2,000,000.

       6.18.   Representations and Warranties of each Subsidiary Borrower. Each
Subsidiary Borrower represents and warrants to the Lenders that:

       (A) Organization and Corporate Powers. Such Subsidiary Borrower (i) is a
company duly formed and validly existing and in good standing under the laws of
the state or country of its organization (such jurisdiction being hereinafter
referred to as the "HOME COUNTRY") and (ii) has the requisite power and
authority to own its property and assets and to carry on its business
substantially as now conducted except where the failure to have such requisite
authority would not reasonably be expected to have a Material Adverse Effect.

       (B) Binding Effect. Each Loan Document executed by such Subsidiary
Borrower is the legal, valid and binding obligation of such Subsidiary Borrower
enforceable in accordance with its respective terms, except as enforceability
may be limited by bankruptcy, insolvency or similar laws affecting the
enforcement of creditors' rights generally and general equitable principles.

       (C) No Conflict; Government Consent. Neither the execution and delivery
by such Subsidiary Borrower of the Loan Documents to which it is a party, nor
the consummation by it of the transactions therein contemplated to be
consummated by it, nor compliance by such Subsidiary Borrower with the
provisions thereof will violate any law, rule, regulation, order, writ,
judgment, injunction, decree or award binding on such Subsidiary Borrower or any
of its Subsidiaries or such Subsidiary Borrower's or any of its Subsidiaries'
memoranda or articles of association or the provisions of any indenture,
instrument or agreement to which such Subsidiary Borrower or any of its
Subsidiaries is a party or is subject, or by which it, or its property, is
bound, or conflict with or constitute a default thereunder, or result in the
creation or imposition of any lien in, of or on the property of such Subsidiary
Borrower or any of its Subsidiaries pursuant to the terms of any such indenture,
instrument or agreement in any such case which violation, conflict, default,
creation or imposition would not reasonably be expected to have a Material
Adverse Effect. No order, consent, approval, license, authorization, or
validation of, or filing, recording or registration with, or exemption by, any
Governmental Authority is required to authorize, or is required in connection
with the execution, delivery and performance of, or the legality, validity,
binding effect or enforceability of, any of the Loan Documents, except for such
as have been obtained or made.

       (D) Filing. To ensure the enforceability or admissibility in evidence of
this Agreement and each Loan Document to which such Subsidiary Borrower is a
party in its Home Country, it is not necessary that this Agreement or any other
Loan Document to which such Subsidiary Borrower is a party or any other document
be filed or recorded with any court or other authority in its Home Country or
that any stamp or similar tax be paid to or in respect of this Agreement or any
other Loan Document of such Subsidiary Borrower. The qualification by any Lender
or the Administrative Agent for admission to do business under the laws of such
Subsidiary Borrower's Home Country does not constitute a condition to, and the
failure to so

                                       63
<PAGE>   74
qualify does not affect, the exercise by any Lender or the Administrative Agent
of any right, privilege, or remedy afforded to any Lender or the Administrative
Agent in connection with the Loan Documents to which such Subsidiary Borrower is
a party or the enforcement of any such right, privilege, or remedy against
Subsidiary Borrower. The performance by any Lender or the Administrative Agent
of any action required or permitted under the Loan Documents will not (i)
violate any law or regulation of such Subsidiary Borrower's Home Country or any
political subdivision thereof, (ii) result in any tax or other monetary
liability to such party pursuant to the laws of such Subsidiary Borrower's Home
Country or political subdivision or taxing authority thereof (provided that,
should any such action result in any such tax or other monetary liability to the
Lender or the Administrative Agent, the Borrowers hereby agree to indemnify such
Lender or the Administrative Agent, as the case may be, against (x) any such tax
or other monetary liability and (y) any increase in any tax or other monetary
liability which results from such action by such Lender or the Administrative
Agent and, to the extent the Borrowers make such indemnification, the incurrence
of such liability by the Administrative Agent or any Lender will not constitute
a Default) or (iii) violate any rule or regulation of any federation or
organization or similar entity of which the such Subsidiary Borrower's Home
Country is a member.

       (E) No Immunity. Neither such Subsidiary Borrower nor any of its assets
is entitled to immunity from suit, execution, attachment or other legal process.
Such Subsidiary Borrower's execution and delivery of the Loan Documents to which
it is a party constitute, and the exercise of its rights and performance of and
compliance with its obligations under such Loan Documents will constitute,
private and commercial acts done and performed for private and commercial
purposes.

       (F) Application of Representations and Warranties. It is understood and
agreed by the parties hereto that the representations and warranties of each
Subsidiary Borrower in this Section 6.18 shall only be applicable to such
Subsidiary Borrower on and after the date of its execution of an Assumption
Letter.

       6.19. Benefits. Each of the Company and its Subsidiaries will benefit
from the financing arrangement established by this Agreement. The Administrative
Agent and the Lenders have stated and the Company acknowledges that, but for the
agreement by each of the Subsidiary Guarantors to execute and deliver the
Subsidiary Guaranty, the Administrative Agent and the Lenders would not have
made available the credit facilities established hereby on the terms set forth
herein.

       6.20.   Acquisition Transactions. As of the closing date for the H-B
Acquisition and immediately prior to the making of any Loans for the purpose of
financing the H-B Acquisition:

               (i) the H-B Acquisition Agreement is in full force and effect, no
       material breach, default or waiver of any term or provision thereof by
       the Company or any of its Subsidiaries or, to the best of the Company's
       knowledge, the other parties thereto, has occurred (except for such
       breaches, defaults and waivers, if any, consented to in writing by the
       Administrative Agent) and no action has been taken by any competent
       authority which restrains, prevents or imposes any material adverse
       condition upon, or seeks to restrain, prevent or impose any material
       adverse condition upon, the H-B Acquisition;

                                       64
<PAGE>   75
               (ii) the representations and warranties of the Company and its
       Subsidiaries contained in the H-B Acquisition Agreement, if any, are true
       and correct in all material respects; and

               (iii) all conditions precedent to, and all consents necessary to
       permit, the funding of the H-B Acquisition have been satisfied or waived
       with the approval of the Administrative Agent (such approval not to be
       unreasonably withheld).

       6.21. Solvency. After giving effect to (i) the Loans to be made on the
Closing Date or such other date as Loans requested hereunder are made, (ii) the
other transactions contemplated by this Agreement and the other Transaction
Documents and (iii) the payment and accrual of all transaction costs with
respect to the foregoing, the Company and its Subsidiaries taken as a whole are
Solvent.

                           ARTICLE VII:      COVENANTS

       The Company covenants and agrees that so long as any Commitments are
outstanding and thereafter until all of the Termination Conditions have been

       quarter, certified by a Financial Officer of the Company on behalf of the
       Company and its Subsidiaries as fairly presenting the consolidated

       corresponding figures for the previous fiscal year along with
       consolidating schedules in form and substance sufficient to calculate the
       financial covenants set forth in Section 7.4, and (b) an audit report on
       the consolidated financial statements (but not the consolidating
       financial statements or schedules) listed in clause (a) hereof of
       independent certified public accountants of recognized national standing,

                                       65
<PAGE>   76
       unqualified and shall state that such financial statements fairly present
       the consolidated financial position of the Company and its Subsidiaries
       as at the dates indicated and the results of their operations and cash
       flows for the periods indicated in conformity with Agreement Accounting
       Principles and that the examination by such accountants in connection
       with such consolidated financial statements has been made in accordance
       with generally accepted auditing standards. The deliveries made pursuant
       to this clause (ii) shall be accompanied by (x) any management letter
       prepared by the above-referenced accountants, and (y) a certificate of
       such accountants that, in the course of their examination necessary for
       their certification of the foregoing, they have obtained no knowledge of

       such representation and warranty shall be true and correct as of such
       date) at all times during the period covered by such financial statements
       and as of the date of such Officer's Certificate and (y) as of the date
       of such Officer's Certificate no Default or Unmatured Default exists, or

       Company shall cause such Subsidiary to deliver to the Administrative
       Agent an executed Supplement to become a Subsidiary Guarantor and
       appropriate corporate resolutions, opinions and other documentation in
       form and

       the guaranty of such other Indebtedness.

       Subsidiary otherwise required to become a Guarantor under paragraphs (ii)
       or (iii) above would cause the Company adverse tax consequences if it
       were to become a Guarantor or is restricted from becoming a Guarantor as
       a result of domestic laws or otherwise, the Administrative Agent may, in
       its discretion, permit such Subsidiary to be treated as an Excluded
       Foreign Subsidiary, and, accordingly, such Subsidiary would not be
       required to become a Guarantor.

       (L) Foreign Employee Benefit Compliance. The Company shall, and shall
cause each of its Subsidiaries and each member of its Controlled Group to,
establish, maintain and operate all Foreign Employee Benefit Plans to comply in
all material respects with all laws, regulations and rules applicable thereto

likely to subject the Company or any of its Subsidiaries to liability,
individually or in the aggregate, in excess of $5,000,000.

Equity Interests of the Company, or with any Affiliate of the Company which is

       similar process against any substantial part of the property of the
       Company or any of the Company's Subsidiaries shall be issued and any such

any of the Company's Subsidiaries shall (i) commence a voluntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in

law, (iii) consent to the appointment of or taking possession by a

                                       82
<PAGE>   93
receiver, trustee or other custodian for all or a substantial part of its
property, (iv) make any assignment for the benefit of creditors or (v) take any

period of thirty (30) days or in any event later than fifteen (15) days prior to
the date of any proposed sale thereunder.

       (I) Dissolution. Any order, judgment or decree shall be entered against
the Company or any Subsidiary decreeing its involuntary dissolution or split up
and such order shall remain undischarged and unstayed for a period in excess of
forty-five (45) days; or the Company or any Subsidiary shall otherwise dissolve
or cease to exist except as specifically permitted by this Agreement.

       (J) Loan Documents. At any time, for any reason, any Loan Document as a
whole that materially affects the ability of the Administrative Agent, or any of
the Lenders to enforce the Obligations ceases to be in full force and effect or
the Company or any of the Company's Subsidiaries party thereto seeks to
repudiate its obligations thereunder.

       (K) Termination Event. Any Termination Event occurs which the Required
Lenders believe is reasonably likely to subject the Company to liability in
excess of $5,000,000.

       (L) Waiver of Minimum Funding Standard. If the plan administrator of any
Plan applies under Section 412(d) of the Code for a waiver of the minimum
funding standards of Section 412(a) of the Code and any Lender believes the
substantial business hardship upon which the application for the waiver is based
could reasonably be expected to subject either the Company or any Controlled

       (M) Change of Control. A Change of Control shall occur.

       (N) Environmental Matters. The Company or any of its Subsidiaries shall

individually or in the aggregate in excess of $5,000,000.

       (O) Guarantor Revocation. Any Guarantor of the Obligations shall

                                       83
<PAGE>   94
ARTICLE IX:      ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

       9.1. Termination of Commitments; Acceleration. If any Default described
in Section 8.1(F) or 8.1(G) occurs with respect to the Company, any Subsidiary
Borrower or any Subsidiary Guarantor, the obligations of the Lenders to make
Loans hereunder and the obligation of any Issuing Banks to issue Letters of
Credit hereunder shall automatically terminate and the Obligations shall
immediately become due and payable without any election or action on the part of
the Administrative Agent or any Lender. If any other Default occurs, the
Required Lenders may terminate or suspend the obligations of the Lenders to make
Loans hereunder and the obligation of the Issuing Banks to issue Letters of
Credit hereunder, or declare the Obligations to be due and payable, or both,
whereupon the Obligations shall become immediately due and payable, without
presentment, demand, protest or notice of any kind, all of which the Borrowers
expressly waive.

       9.2. Amendments. Subject to the provisions of this Article IX, the
Required Lenders (or the Administrative Agent with the consent in writing of the
Required Lenders) and the Borrowers may enter into agreements supplemental
hereto for the purpose of adding or modifying any provisions to the Loan
Documents or changing in any manner the rights of the Lenders or the Borrowers
hereunder or waiving any Default hereunder; provided, however, that no such
supplemental agreement shall, without the consent of each Lender affected
thereby:

               (i) Postpone or extend the Termination Date or any other date
       fixed for any payment of principal of, or interest on, the Loans, the
       Reimbursement Obligations or any fees or other amounts payable to such
       Lender (except with respect to (a) any modifications of the provisions
       relating to amounts, timing or application of prepayments of Loans and
       other Obligations, which modification shall require only the approval of
       the Required Lenders and (b) a waiver of the application of the default
       rate of interest pursuant to Section 2.10 hereof which waiver shall
       require only the approval of the Required Lenders).

               (ii) Reduce the principal Dollar Amount of any Loans or L/C
       Obligations, or reduce the rate or extend the time of payment of interest
       or fees thereon (other than a waiver of the application of the default
       rate of interest pursuant to Section 2.10 hereof).

               (iii) Reduce the percentage specified in the definition of
       Required Lenders or any other percentage of Lenders specified to be the
       applicable percentage in this Agreement to act on specified matters or
       amend the definitions of "Required Lenders" or "Pro Rata Share".

               (iv) Increase the amount of the Commitment, of any Lender
       hereunder, or increase any Lender's Pro Rata Share.

               (v) Permit the Company or, other than pursuant to a transaction
       permitted under the terms of this Agreement, any Subsidiary Borrower to
       assign its rights under this Agreement.

                                       84
<PAGE>   95
               (vi) Other than pursuant to a transaction permitted by the terms
       of this Agreement, release any Guarantor from its obligations under the
       Guaranty.

               (vii) Amend Section 7.2(K), Section 13.2, Section 13.3 or this
Section 9.2.

No amendment of any provision of this Agreement relating to (a) the
Administrative Agent shall be effective without the written consent of the
Administrative Agent, (b) Swing Line Loans shall be effective without the
written consent of the Swing Line Bank and (c) any Issuing Bank shall be
effective without the written consent of such Issuing Bank. The Administrative
Agent may waive payment of the fee required under Section 14.3(B) without
obtaining the consent of any of the Lenders. Notwithstanding anything herein to
the contrary, the Administrative Agent may amend the provisions of Exhibit A
from time to time to take into account the effectiveness of assignments made
pursuant to Section 14.3 or changes in the Commitments pursuant to Section
2.5(B), provided the failure to do so shall not otherwise affect the rights or
obligations of the Lenders or the Borrowers hereunder.

               The Administrative Agent may notify the other parties to this
Agreement of any amendments to this Agreement which the Administrative Agent
reasonably determines to be necessary as a result of the commencement of the
third stage of the European Economic and Monetary Union. Notwithstanding
anything to the contrary contained herein, any amendments so notified shall take
effect in accordance with the terms of the relevant notification.

       9.3. Preservation of Rights. No delay or omission of the Lenders or the
Administrative Agent to exercise any right under the Loan Documents shall impair
such right or be construed to be a waiver of any Default or an acquiescence
therein, and the making of a Loan or the issuance of a Letter of Credit
notwithstanding the existence of a Default or the inability of the Company or
any other Borrower to satisfy the conditions precedent to such Loan or issuance
of such Letter of Credit shall not constitute any waiver or acquiescence. Any
single or partial exercise of any such right shall not preclude other or further
exercise thereof or the exercise of any other right, and no waiver, amendment or
other variation of the terms, conditions or provisions of the Loan Documents
whatsoever shall be valid unless in writing signed by the requisite number of
Lenders required pursuant to Section 9.2, and then only to the extent in such
writing specifically set forth. All remedies contained in the Loan Documents or
by law afforded shall be cumulative and all shall be available to the
Administrative Agent and the Lenders until all of the Termination Conditions
shall have been satisfied.

                               ARTICLE X:  GUARANTY

       10.1. Guaranty. For valuable consideration, the receipt of which is
hereby acknowledged, and to induce the Lenders to make advances to each Borrower
and to issue and participate in Letters of Credit and Swing Line Loans, the
Company and each Subsidiary Borrower (collectively, the "BORROWER GUARANTORS")
hereby absolutely and unconditionally guarantees prompt payment when due,
whether at stated maturity, upon acceleration or otherwise, and at all times
thereafter, of any and all existing and future Obligations of each Borrower to
the Administrative Agent, the Lenders, the Swing Line Bank, the Issuing Banks,
or

                                       85
<PAGE>   96
any of them, under or with respect to the Loan Documents, whether for principal,
interest, fees, expenses or otherwise (collectively, the "GUARANTEED
OBLIGATIONS").

       10.2.  Waivers; Subordination of Subrogation.

               (i) Each Borrower Guarantor waives notice of the acceptance of
       this guaranty and of the extension or continuation of the Guaranteed
       Obligations or any part thereof. Each Borrower Guarantor further waives
       presentment, protest, notice of notices delivered or demand made on any
       Borrower or action or delinquency in respect of the Guaranteed
       Obligations or any part thereof, including any right to require the
       Administrative Agent and the Lenders to sue any Borrower, any other
       guarantor or any other Person obligated with respect to the Guaranteed
       Obligations or any part thereof; provided, that if at any time any
       payment of any portion of the Guaranteed Obligations is rescinded or must
       otherwise be restored or returned upon the insolvency, bankruptcy or
       reorganization of any of the Borrowers or otherwise, the Borrower
       Guarantor's obligations hereunder with respect to such payment shall be
       reinstated at such time as though such payment had not been made and
       whether or not the Administrative Agent or the Lenders are in possession
       of this guaranty. The Administrative Agent and the Lenders shall have no
       obligation to disclose or discuss with the Company their assessments of
       the financial condition of the Borrowers.

               (ii) Until the Guaranteed Obligations have been indefeasibly paid
       in full in cash, each Borrower Guarantor (i) shall have no right of
       subrogation with respect to such Guaranteed Obligations and (ii) waives
       any right to enforce any remedy which the Administrative Agent now has or
       may hereafter have against any Borrower, any other Guarantor, any
       endorser or any guarantor of all or any part of the Guaranteed
       Obligations or any other Person. Should any Borrower Guarantor have the
       right, notwithstanding the foregoing, to exercise its subrogation rights,
       each Borrower Guarantor hereby expressly and irrevocably (A) subordinates
       any and all rights at law or in equity to subrogation, reimbursement,
       exoneration, contribution, indemnification or set off that such Borrower
       Guarantor may have to the indefeasible payment in full in cash of the
       Guaranteed Obligations and (B) waives any and all defenses available to a
       surety, guarantor or accommodation co-obligor until the Guaranteed
       Obligations are indefeasibly paid in full in cash. Each Borrower
       Guarantor acknowledges and agrees that this subordination is intended to
       benefit the Administrative Agent and shall not limit or otherwise affect
       any Borrower Guarantor liability hereunder or the enforceability of this
       Guaranty, and that the Administrative Agent, the Lenders and their its
       successors and assigns are intended third party beneficiaries of the
       waivers and agreements set forth in this Section 10.2.

       10.3. Guaranty Absolute. This guaranty is a guaranty of payment and not
of collection, is a primary obligation of each Borrower Guarantor and not one of
surety, and the validity and enforceability of this guaranty shall be absolute
and unconditional irrespective of, and shall not be impaired or affected by any
of the following: (a) any extension, modification or renewal of, or indulgence
with respect to, or substitutions for, the Guaranteed Obligations or any part
thereof or any agreement relating thereto at any time; (b) any failure or
omission to enforce any right, power or remedy with respect to the Guaranteed
Obligations or any part thereof or any

                                       86
<PAGE>   97
agreement relating thereto; (c) any waiver of any right, power or remedy with
respect to the Guaranteed Obligations or any part thereof or any agreement
relating thereto; (d) any release, surrender, compromise, settlement, waiver,
subordination or modification, with or without consideration, any other
guaranties with respect to the Guaranteed Obligations or any part thereof, or
any other obligation of any Person with respect to the Guaranteed Obligations or
any part thereof; (e) the enforceability or validity of the Guaranteed
Obligations or any part thereof or the genuineness, enforceability or validity
of any agreement relating thereto; (f) the application of payments received from
any source to the payment of obligations other than the Guaranteed Obligations,
any part thereof or amounts which are not covered by this guaranty even though
the Administrative Agent and the Lenders might lawfully have elected to apply
such payments to any part or all of the Guaranteed Obligations or to amounts
which are not covered by this guaranty; (g) any change in the ownership of any
Borrower or the insolvency, bankruptcy or any other change in the legal status
of any Borrower; (h) the change in or the imposition of any law, decree,
regulation or other governmental act which does or might impair, delay or in any
way affect the validity, enforceability or the payment when due of the
Guaranteed Obligations; (i) the failure of the Company or any other Borrower to
maintain in full force, validity or effect or to obtain or renew when required
all governmental and other approvals, licenses or consents required in
connection with the Guaranteed Obligations or this guaranty, or to take any
other action required in connection with the performance of all obligations
pursuant to the Guaranteed Obligations or this guaranty; (j) the existence of
any claim, setoff or other rights which the Company may have at any time against
any Borrower, or any other Person in connection herewith or an unrelated
transaction; or (k) any other circumstances, whether or not similar to any of
the foregoing, which could constitute a defense to a guarantor; all whether or
not such Borrower Guarantor shall have had notice or knowledge of any act or
omission referred to in the foregoing clauses (a) through (k) of this paragraph.
It is agreed that each Borrower Guarantor's liability hereunder is several and
independent of any other guaranties or other obligations at any time in effect
with respect to the Guaranteed Obligations or any part thereof and that each
Borrower Guarantor's liability hereunder may be enforced regardless of the
existence, validity, enforcement or non-enforcement of any such other guaranties
or other obligations or any provision of any applicable law or regulation
purporting to prohibit payment by any Borrower of the Guaranteed Obligations in
the manner agreed upon between the Borrower and the Administrative Agent and the
Lenders.

       10.4. Acceleration. Each Borrower Guarantor agrees that, as between such
Borrower Guarantor on the one hand, and the Lenders and the Administrative
Agent, on the other hand, the obligations of each Borrower guaranteed under this
Article X may be declared to be forthwith due and payable, or may be deemed
automatically to have been accelerated, as provided in Section 9.1 hereof for
purposes of this Article X, notwithstanding any stay, injunction or other
prohibition (whether in a bankruptcy proceeding affecting such Borrower or
otherwise) preventing such declaration as against such Borrower and that, in the
event of such declaration or automatic acceleration, such obligations (whether
or not due and payable by such Borrower) shall forthwith become due and payable
by each Borrower Guarantor for purposes of this Article X.

       10.5. Marshaling; Reinstatement. None of the Lenders nor the
Administrative Agent nor any Person acting for or on behalf of the Lenders or
the Administrative Agent shall have any

                                       87
<PAGE>   98
obligation to marshal any assets in favor of any Borrower Guarantor or against
or in payment of any or all of the Guaranteed Obligations. If any Borrower
Guarantor or any other guarantor of all or any part of the Guaranteed
Obligations makes a payment or payments to any Lender or the Administrative
Agent, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to any Borrower Guarantor or any other guarantor or any
other Person, or their respective estates, trustees, receivers or any other
party, including, without limitation, each Borrower Guarantor, under any
bankruptcy law, state or federal law, common law or equitable cause, then, to
the extent of such payment or repayment, the part of the Guaranteed Obligations
which has been paid, reduced or satisfied by such amount shall be reinstated and
continued in full force and effect as of the time immediately preceding such
initial payment, reduction or satisfaction.

       10.6. Termination Date. This guaranty shall continue in effect until the
earlier of (a) the Facility Termination Date, and (b) the date on which this
Agreement has otherwise expired or been terminated in accordance with its terms
and all of the Guaranteed Obligations have been paid in full in cash, subject to
the proviso in Section 10.2.

                     ARTICLE XI:      GENERAL PROVISIONS

       11.1. Survival of Representations. All representations and warranties of
the Borrowers contained in this Agreement shall survive delivery of this
Agreement and the making of the Loans herein contemplated so long as any
principal, accrued interest, fees, or any other amount due and payable under any
Loan Document is outstanding and unpaid (other than contingent reimbursement and
indemnification obligations) and so long as the Commitments have not been
terminated.

       11.2. Governmental Regulation. Anything contained in this Agreement to
the contrary notwithstanding, no Lender shall be obligated to extend credit to
the Company or any other Borrower in violation of any limitation or prohibition
provided by any applicable statute or regulation.

       11.3. Performance of Obligations. The Borrowers agree that the
Administrative Agent may, but shall have no obligation to (i) at any time, pay
or discharge taxes, liens, security interests or other encumbrances levied or
placed on or threatened against any property of any Borrower to the extent any
such Borrower is required by the terms hereof to pay any such amount, but has
not done so and (ii), after the occurrence and during the continuance of a
Default, to make any other payment or perform any act required of the Company or
any other Borrower under any Loan Document or take any other action which the
Administrative Agent in its discretion deems necessary or desirable to protect
or preserve such property of the Company. The Administrative Agent shall use its
reasonable efforts to give the applicable Borrower notice of any action taken
under this Section 11.3 prior to the taking of such action or promptly
thereafter provided the failure to give such notice shall not affect the
applicable Borrower's obligations in respect thereof. The Borrowers agree to pay
the Administrative Agent, upon demand, the principal amount of all funds
advanced by the Administrative Agent under this Section 11.3, together with
interest thereon at the rate from time to time applicable to Floating

                                       88
<PAGE>   99
Rate Loans from the date of such advance until the outstanding principal balance
thereof is paid in full. If any Borrower fails to make payment in respect of any
such advance under this Section 11.3 within one (1) Business Day after the date
the applicable Borrower receives written demand therefor from the Administrative
Agent, the Administrative Agent shall promptly notify each Lender and each
Lender agrees that it shall thereupon make available to the Administrative
Agent, in Dollars in immediately available funds, the amount equal to such
Lender's Pro Rata Share of such advance. If such funds are not made available to
the Administrative Agent by such Lender within one (1) Business Day after the
Administrative Agent's demand therefor, the Administrative Agent will be
entitled to recover any such amount from such Lender together with interest
thereon at the Federal Funds Effective Rate for each day during the period
commencing on the date of such demand and ending on the date such amount is
received. The failure of any Lender to make available to the Administrative
Agent its Pro Rata Share of any such unreimbursed advance under this Section
11.3 shall neither relieve any other Lender of its obligation hereunder to make
available to the Administrative Agent such other Lender's Pro Rata Share of such
advance on the date such payment is to be made nor increase the obligation of
any other Lender to make such payment to the Administrative Agent.

       11.4. Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

       11.5. Entire Agreement. The Loan Documents and the letter agreement
between the Administrative Agent, the Arranger and the Borrowers dated September
6, 2000 embody the entire agreement and understanding among the Borrowers, the
Administrative Agent and the Lenders and supersede all prior agreements and
understandings among the Borrowers, the Administrative Agent and the Lenders
relating to the subject matter thereof.

       11.6. Several Obligations; Benefits of this Agreement. The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other Lender (except to the extent to which
the Administrative Agent is authorized to act as such). The failure of any
Lender to perform any of its obligations hereunder shall not relieve any other
Lender from any of its obligations hereunder. This Agreement shall not be
construed so as to confer any right or benefit upon any Person other than the
parties to this Agreement and their respective successors and assigns.

       11.7.  Expenses; Indemnification.

       (A) Expenses. The Borrowers shall reimburse the Administrative Agent and
the Arranger for any reasonable costs, internal charges and out-of-pocket
expenses (including reasonable attorneys' and paralegals' fees and time charges
of attorneys and paralegals for the Administrative Agent, which attorneys and
paralegals may be employees of the Administrative Agent) paid or incurred by the
Administrative Agent or the Arranger in connection with the preparation,
negotiation, execution, delivery, syndication, distribution (including via the
internet), review, amendment, modification, and administration of the Loan
Documents. The Borrowers also agree to reimburse the Administrative Agent and
the Arranger and the Lenders for any costs, internal charges and out-of-pocket
expenses (including attorneys' and paralegals'

                                       89
<PAGE>   100
fees and time charges of attorneys and paralegals for the Administrative Agent
and the Arranger and the Lenders, which attorneys and paralegals may be
employees of the Administrative Agent or the Arranger or the Lenders) paid or
incurred by the Administrative Agent or the Arranger or any Lender in connection
with the collection of the Obligations and enforcement of the Loan Documents. In
addition to expenses set forth above, the Borrowers agree to reimburse the
Administrative Agent, promptly after the Administrative Agent's request
therefor, for each audit, or other business analysis performed by or for the
benefit of the Lenders in connection with this Agreement or the other Loan
Documents in an amount equal to the Administrative Agent's then customary
charges for each person employed to perform such audit or analysis, plus all
costs and expenses (including without limitation, travel expenses) incurred by
the Administrative Agent in the performance of such audit or analysis.
Administrative Agent shall provide the Borrowers with a detailed statement of
all reimbursements requested under this Section 11.7(A).

       (B) Indemnity. The Borrowers further agree to defend, protect, indemnify,
and hold harmless the Administrative Agent, the Arranger and each and all of the
Lenders and each of their respective Affiliates, and each of such Administrative
Agent's, Arranger's, Lender's, or Affiliate's respective officers, directors,
trustees, investment advisors, employees, attorneys and agents (including,
without limitation, those retained in connection with the satisfaction or
attempted satisfaction of any of the conditions set forth in Article V)
(collectively, the "INDEMNITEES") from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, claims,
costs, expenses of any kind or nature whatsoever (including, without limitation,
the fees and disbursements of counsel for such Indemnitees in connection with
any investigative, administrative or judicial proceeding, whether or not any of
such Indemnitees shall be designated a party thereto), imposed on, incurred by,
or asserted against such Indemnitees in any manner relating to or arising out
of:

               (i) this Agreement or any of the other Loan Documents, or any
       act, event or transaction related or attendant thereto or to the making
       of the Loans, and the issuance of and participation in Letters of Credit
       hereunder, the management of such Loans or Letters of Credit, the use or
       intended use of the proceeds of the Loans or Letters of Credit hereunder,
       or any of the other transactions contemplated by the Loan Documents; or

               (ii) any liabilities, obligations, responsibilities, losses,
       damages, personal injury, death, punitive damages, economic damages,
       consequential damages, treble damages, intentional, willful or wanton
       injury, damage or threat to the environment, natural resources or public
       health or welfare, costs and expenses (including, without limitation,
       attorney, expert and consulting fees and costs of investigation,
       feasibility or remedial action studies), fines, penalties and monetary
       sanctions, interest, direct or indirect, known or unknown, absolute or
       contingent, past, present or future relating to violation of any
       Environmental, Health or Safety Requirements of Law arising from or in
       connection with the past, present or future operations of the Company,
       its Subsidiaries or any of their respective predecessors in interest, or,
       the past, present or future environmental, health or safety condition of
       any respective property of the Company or its Subsidiaries, the presence
       of asbestos-containing materials at any respective property of the
       Company or its Subsidiaries or the Release or threatened Release of any
       Contaminant into the environment (collectively, the "INDEMNIFIED
       MATTERS");

                                       90
<PAGE>   101
provided, however, no Borrower shall have any obligation to an Indemnitee
hereunder with respect to Indemnified Matters caused solely by or resulting
solely from the willful misconduct or Gross Negligence of such Indemnitee with
respect to the Loan Documents, as determined by the final non-appealed judgment
of a court of competent jurisdiction. If the undertaking to indemnify, pay and
hold harmless set forth in the preceding sentence may be unenforceable because
it is violative of any law or public policy, the applicable Borrower shall
contribute the maximum portion which it is permitted to pay and satisfy under
applicable law, to the payment and satisfaction of all Indemnified Matters
incurred by the Indemnitees.

       (C) Waiver of Certain Claims; Settlement of Claims. Neither the
Administrative Agent, the Arranger, any Lender nor the Company or any other
Borrower shall be liable under this Agreement or any Loan Document or in respect
of any act, omission or event relating to the transaction contemplated hereby or
thereby, on any theory of liability on any theory of liability seeking
consequential, special, indirect, exemplary or punitive damages. No settlement
shall be entered into by the Company or any of its Subsidiaries with respect to
any claim, litigation, arbitration or other proceeding relating to or arising
out of the transactions evidenced by this Agreement or the other Loan Documents
(whether or not the Administrative Agent or any Lender or any Indemnitee is a
party thereto) unless such settlement releases all Indemnitees from any and all
liability with respect thereto.

       (D) Survival of Agreements. The obligations and agreements of the
Borrowers under this Section 11.7 shall survive the termination of this
Agreement.

       11.8. Numbers of Documents. All statements, notices, closing documents,
and requests hereunder shall be furnished to the Administrative Agent with
sufficient counterparts so that the Administrative Agent may furnish one to each
of the Lenders.

       11.9. Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles. If any changes in generally accepted accounting principles are
hereafter required or permitted and are adopted by the Company or any of its
Subsidiaries with the agreement of its independent certified public accountants
and such changes result in a change in the method of calculation of any of the
financial covenants, tests, restrictions or standards herein or in the related
definitions or terms used therein ("ACCOUNTING CHANGES"), the parties hereto
agree, at the Company's request, to enter into negotiations, in good faith, in
order to amend such provisions in a credit neutral manner so as to reflect
equitably such changes with the desired result that the criteria for evaluating
the Company's and its Subsidiaries' financial condition shall be the same after
such changes as if such changes had not been made; provided, however, until such
provisions are amended in a manner reasonably satisfactory to the Administrative
Agent and the Required Lenders, no Accounting Change shall be given effect in
such calculations and all financial statements and reports required to be
delivered hereunder shall be prepared in accordance with Agreement Accounting
Principles without taking into account such Accounting Changes. In the event
such amendment is entered into, all references in this Agreement to Agreement
Accounting Principles shall mean generally accepted accounting principles as of
the date of such amendment.

       11.10. Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

       11.11. Nonliability of Lenders. The relationship between the Borrowers
and the Lenders and the Administrative Agent shall be solely that of borrower
and lender. Neither the Administrative Agent nor any Lender shall have any
fiduciary responsibilities to the Borrowers. Neither the Administrative Agent
nor any Lender undertakes any responsibility to any Borrower to review or inform
any Borrower of any matter in connection with any phase of the Borrowers'
business or operations.

Arranger, the Lenders, the Swing Line Bank, the Issuing Banks and the Borrowers
acknowledge that the Lenders (or Affiliates of the Lenders) may, from time to
time, effect transactions for their own accounts or

                                       93
<PAGE>   104
the accounts of customers, and hold positions in loans or options on loans of
the Company, the Company's Subsidiaries and other companies that may be the
subject of this credit arrangement and nothing in this Agreement shall impair
the right of any such Person to enter into any such transaction (to the extent
it is not expressly prohibited by the terms of this Agreement) or give any other
Person any claim or right of action hereunder as a result of the existence of
the credit arrangements hereunder, all of which are hereby waived. In addition,
certain Affiliates of one or more of the Lenders are or may be securities firms
and as such may effect, from time to time, transactions for their own accounts
or for the accounts of customers and hold positions in securities or options on
securities of the Company, the Company's Subsidiaries and other companies that
may be the subject of this credit arrangement and nothing in this Agreement
shall impair the right of any such Person to enter into any such transaction (to
the extent it is not expressly prohibited by the terms of this Agreement) or
give any other Person any claim or right of action hereunder as a result of the
existence of the credit arrangements hereunder, all of which are hereby waived.
Each of the Administrative Agent, the Arranger and Arranger, the Lenders, the
Swing Line Bank, the Issuing Banks and the Borrowers acknowledges and consents
to these multiple roles, and further acknowledges that the fact that any such
unit or Affiliate is providing another service or product or proposal therefor
to the Company or any of its Subsidiaries does not mean that such service,
product, or proposal is or will be acceptable to any of the Administrative
Agent, the Arranger and Arranger, the Lenders, the Swing Line Bank or the
Issuing Banks.

       11.15. Subordination of Intercompany Indebtedness. Each Borrower agrees
that any and all claims of such Borrower against the Company or any of its
Subsidiaries that is a Guarantor with respect to any "Intercompany Indebtedness"
(as hereinafter defined), any endorser, obligor or any other guarantor of all or
any part of the Obligations, or against any of its properties shall be
subordinate and subject in right of payment to the prior payment, in full and in
cash, of all Obligations and Hedging Obligations under Hedging Arrangements
entered into with the Lenders or any of their Affiliates ("DESIGNATED HEDGING
AGREEMENTS"); provided that, and not in contravention of the foregoing, so long
as no Default has occurred and is continuing each Borrower may make loans to and
receive payments in the ordinary course with respect to such Intercompany
Indebtedness from each such Guarantor to the extent not prohibited by the terms
of this Agreement and the other Loan Documents. Notwithstanding any right of any
Borrower to ask, demand, sue for, take or receive any payment from any
Guarantor, all rights, liens and security interests of any Borrower, whether now
or hereafter arising and howsoever existing, in any assets of any Guarantor
shall be and are subordinated to the rights of the holders of the Obligations
and the Administrative Agent in those assets. No Borrower shall have any right
to possession of any such asset or to foreclose upon any such asset, whether by
judicial action or otherwise, unless and until all of the Obligations (other
than contingent indemnity obligations) and the Hedging Obligations under
Designated Hedging Agreements shall have been fully paid and satisfied (in cash)
and all financing arrangements pursuant to any Loan Document or Designated
Hedging Agreement have been terminated. If all or any part of the assets of any
Guarantor, or the proceeds thereof, are subject to any distribution, division or
application to the creditors of such Guarantor, whether partial or complete,
voluntary or involuntary, and whether by reason of liquidation, bankruptcy,
arrangement, receivership, assignment for the benefit of creditors or any other
action or proceeding, or if the business of any such Guarantor is dissolved or
if substantially all of the assets of any such Guarantor are sold, then, and in
any such event

                                       94
<PAGE>   105
(such events being herein referred to as an "INSOLVENCY EVENT"), any payment or
distribution of any kind or character, either in cash, securities or other
property, which shall be payable or deliverable upon or with respect to any
indebtedness of any Guarantor to any Borrower ("INTERCOMPANY INDEBTEDNESS")
shall be paid or delivered directly to the Administrative Agent for application
on any of the Obligations and Hedging Obligations under Designated Hedging
Agreements, due or to become due, until such Obligations and Hedging Obligations
(other than contingent indemnity obligations) shall have first been fully paid
and satisfied (in cash). Should any payment, distribution, security or
instrument or proceeds thereof be received by any Borrower upon or with respect
to the Intercompany Indebtedness after an Insolvency Event prior to the
satisfaction of all of the Obligations (other than contingent indemnity
obligations) and Hedging Obligations under Designated Hedging Agreements and the
termination of all financing arrangements pursuant to any Loan Document and or
Designated Hedging Agreements, such Borrower shall receive and hold the same in
trust, as trustee, for the benefit of the holders of the Obligations and such
Hedging Obligations and shall forthwith deliver the same to the Administrative
Agent, for the benefit of such Persons, in precisely the form received (except
for the endorsement or assignment of such Borrower where necessary), for
application to any of the Obligations and such Hedging Obligations, due or not
due, and, until so delivered, the same shall be held in trust by such Borrower
as the property of the holders of the Obligations and such Hedging Obligations.
If any Borrower fails to make any such endorsement or assignment to the
Administrative Agent, the Administrative Agent or any of its officers or
employees are irrevocably authorized to make the same. Each Borrower agrees that
until the Obligations (other than the contingent indemnity obligations) and such
Hedging Obligations have been paid in full (in cash) and satisfied and all
financing arrangements pursuant to any Loan Document or any Designated Hedging
Agreement have been terminated, no Borrower will assign or transfer to any
Person (other than the Administrative Agent) any claim such Borrower has or may
have against any Guarantor.

       11.16. Lender's Not Utilizing Plan Assets. None of the consideration used
by any of the Lenders or Designated Lenders to make its Loans constitutes for
any purpose of ERISA or Section 4975 of the Code assets of any "plan" as defined
in Section 3(3) of ERISA or Section 4975 of the Code and the rights and
interests of each of the Lenders and Designated Lenders in and under the Loan
Documents shall not constitute such "plan assets" under ERISA.

       11.17. Collateral. Each of the Lenders and the Issuing Banks represents
to the Administrative Agent, each of the other Lenders and each of the other
Issuing Banks that it in good faith is not relying upon any "margin stock" (as
defined in Regulation U) as collateral in the extension or maintenance of the
credit provided for in this Agreement.

                 ARTICLE XII:      THE ADMINISTRATIVE AGENT

       12.1. Appointment; Nature of Relationship. Bank One is appointed by the
Lenders as the Administrative Agent hereunder and under each other Loan
Document, and each of the Lenders irrevocably authorizes the Administrative
Agent to act as the contractual representative of such Lender with the rights
and duties expressly set forth herein and in the other Loan Documents. The
Administrative Agent agrees to act as such contractual representative upon the

                                       95
<PAGE>   106
express conditions contained in this Article XII. In its capacity as the
Lenders' contractual representative, the Administrative Agent is acting as an
independent contractor, the rights and duties of which are limited to those
expressly set forth in this Agreement and the other Loan Documents. Each of the
Lenders agrees to assert no claim against the Administrative Agent on any agency
theory or any other theory of liability for breach of fiduciary duty.

       12.2. Powers. The Administrative Agent shall have and may exercise such
powers under the Loan Documents as are specifically delegated to the
Administrative Agent by the terms of each thereof, together with such powers as
are reasonably incidental thereto. The Administrative Agent shall have no
implied duties or fiduciary duties to the Lenders, or any obligation to the
Lenders to take any action hereunder or under any of the other Loan Documents
except any action specifically provided by the Loan Documents required to be
taken by the Administrative Agent.

       12.3. General Immunity. Neither the Administrative Agent nor any of its
directors, officers, agents or employees shall be liable to the Borrowers, the
Lenders or any Lender for any action taken or omitted to be taken by it or them
hereunder or under any other Loan Document or in connection herewith or
therewith except to the extent such action or inaction is found in a final
judgment by a court of competent jurisdiction to have arisen solely from the
Gross Negligence or willful misconduct of such Person.

       12.4. No Responsibility for Loans, Creditworthiness, Recitals, Etc.
Neither the Administrative Agent nor any of its directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into,
or verify (i) any statement, warranty or representation made in connection with
any Loan Document or any borrowing hereunder; (ii) the performance or observance
of any of the covenants or agreements of any obligor under any Loan Document;
(iii) the satisfaction of any condition specified in Article V, except receipt
of items required to be delivered solely to the Administrative Agent; (iv) the
existence or possible existence of any Default or (v) the validity,
effectiveness or genuineness of any Loan Document or any other instrument or
writing furnished in connection therewith. The Administrative Agent shall not be
responsible to any Lender for any recitals, statements, representations or
warranties herein or in any of the other Loan Documents or for the execution,
effectiveness, genuineness, validity, legality, enforceability, collectibility,
or sufficiency of this Agreement or any of the other Loan Documents or the
transactions contemplated thereby, or for the financial condition of any
guarantor of any or all of the Obligations, the Company or any of its
Subsidiaries.

       12.5. Action on Instructions of Lenders. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder and under any other Loan Document in accordance with written
instructions signed by the Required Lenders (or all of the Lenders in the event
that and to the extent that this Agreement expressly requires such), and such
instructions and any action taken or failure to act pursuant thereto shall be
binding on all of the Lenders and on all owners of Loans. The Administrative
Agent shall be fully justified in failing or refusing to take any action
hereunder and under any other Loan Document unless it shall first be indemnified
to its satisfaction by the Lenders pro rata against any and all liability, cost
and expense that it may incur by reason of taking or continuing to take any such
action.

                                       96
<PAGE>   107

       12.6.  Employment of Agents and Counsel. The Administrative Agent may
execute any of its duties as the Administrative Agent hereunder and under any
other Loan Document by or through employees, agents, and attorney-in-fact and
shall not be answerable to the Lenders, except as to money or securities
received by it or its authorized agent, for the default or misconduct of any
such agent or attorneys-in-fact selected by it with reasonable care. The
Administrative Agent shall be entitled to advice of counsel concerning the
contractual arrangement between the Administrative Agent and the Lenders and all
matters pertaining to the Administrative Agent's duties hereunder and under any
other Loan Document.

       12.7.  Reliance on Documents; Counsel. The Administrative Agent shall be
entitled to rely upon any notice, consent, certificate, affidavit, letter,
telegram, statement, paper or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and, in respect
to legal matters, upon the opinion of counsel selected by the Administrative
Agent, which counsel may be employees of the Administrative Agent.

       12.8.  The Administrative Agent's Reimbursement and Indemnification. The
Lenders agree to reimburse and indemnify the Administrative Agent (i) for any
amounts not reimbursed by any Borrower for which the Administrative Agent is
entitled to reimbursement by any Borrower under the Loan Documents, (ii) for any
other expenses incurred by the Administrative Agent in connection with the
preparation, execution, delivery, administration and enforcement of the Loan
Documents and (iii) for any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Administrative Agent in any way relating to or arising out of the
Loan Documents or any other document delivered in connection therewith or the
transactions contemplated thereby, or the enforcement of any of the terms
thereof or of any such other documents, provided that no Lender shall be liable
for any of the foregoing to the extent any of the foregoing is found in a final
non-appealable judgment by a court of competent jurisdiction to have arisen
solely from the Gross Negligence or willful misconduct of the Administrative
Agent.

       12.9.  Rights as a Lender. With respect to its Commitment, Loans made by
it, and Letters of Credit issued by it, the Administrative Agent shall have the
same rights and powers hereunder and under any other Loan Document as any Lender
or Issuing Bank and may exercise the same as though it were not the
Administrative Agent, and the term "Lender" or "Lenders", "Issuing Bank" or
"Issuing Banks" shall, unless the context otherwise indicates, include the
Administrative Agent in its individual capacity. The Administrative Agent may
accept deposits from, lend money to, and generally engage in any kind of trust,
debt, equity or other transaction, in addition to those contemplated by this
Agreement or any other Loan Document, with the Company or any of its
Subsidiaries in which such Person is not prohibited hereby from engaging with
any other Person.

       12.10. Lender Credit Decision.  Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent, the Arranger
or any other Lender and based on the financial statements prepared by the
Company and such other documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement and the
other Loan Documents. Each Lender also acknowledges that it will,

                                       97

<PAGE>   108

independently and without reliance upon the Administrative Agent, the Arranger
or any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement and the other Loan Documents.

       12.11. Successor Administrative Agent. The Administrative Agent may
resign at any time by giving written notice thereof to the Lenders and the
Company. Upon any such resignation, the Required Lenders shall have the right to
appoint, on behalf of the Borrowers and the Lenders, a successor Administrative
Agent. If no successor Administrative Agent shall have been so appointed by the
Required Lenders and shall have accepted such appointment within thirty days
after the retiring Administrative Agent's giving notice of resignation, then the
retiring Administrative Agent may appoint, on behalf of the Borrowers and the
Lenders, a successor Administrative Agent. Notwithstanding anything herein to
the contrary, so long as no Default has occurred and is continuing, each such
successor Administrative Agent shall be subject to approval by the Company,
which approval shall not be unreasonably withheld or delayed. Such successor
Administrative Agent shall be a commercial bank having capital and retained
earnings of at least $500,000,000. Upon the acceptance of any appointment as the
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder and under the other Loan Documents. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this Article XII shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
the Administrative Agent hereunder and under the other Loan Documents.

       12.12. Documentation Agent, Syndication Agent, and Arranger. Neither the
Documentation Agent, the Syndication Agent nor the Arranger shall have any
right, power, obligation, liability, responsibility or duty under this Agreement
other than those applicable to all Lenders as such. Without limiting the
foregoing, none of such Lenders shall have or be deemed to have a fiduciary
relationship with any Lender. Each Lender hereby makes the same acknowledgments
with respect to such Lenders as it makes with respect to the Administrative
Agent in Section 12.10.

                 ARTICLE XIII:     SETOFF; RATABLE PAYMENTS

       13.1.  Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if any Default occurs and is continuing, any
Indebtedness from any Lender to the Company or any other Borrower (including all
account balances, whether provisional or final and whether or not collected or
available) may be offset and applied toward the payment of the Obligations owing
to such Lender, whether or not the Obligations, or any part hereof, shall then
be due.

       13.2.  Ratable Payments.  If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (other than payments received pursuant to
Sections 4.1, 4.2 or 4.4) in a

                                       98

<PAGE>   109

greater proportion than that received by any other Lender, such Lender agrees,
promptly upon demand, to purchase a portion of the Loans held by the other
Lenders so that after such purchase each Lender will hold its ratable proportion
of Loans. In case any such payment is disturbed by legal process, or otherwise,
appropriate further adjustments shall be made.

       13.3.  Application of Payments. The Administrative Agent shall, unless
otherwise specified at the direction of the Required Lenders which direction
shall be consistent with the last two sentences of this Section 13.3, apply all
payments and prepayments in respect of any Obligations in the following order:

              (i)     first, to pay interest on and then principal of any
       portion of the Loans which the Administrative Agent may have advanced on
       behalf of any Lender for which the Administrative Agent has not then been
       reimbursed by such Lender or the applicable Borrower;

               (ii)   second, to pay interest on and then principal of any
       advance made under Section 11.3 for which the Administrative Agent has
       not then been paid by the applicable Borrower or reimbursed by the
       Lenders;

               (iii)  third, to the ratable payment of the Obligations in
       respect of any fees, expenses, reimbursements or indemnities then due to
       the Administrative Agent or the Arranger;

               (iv)   fourth, to pay Obligations in respect of any fees,
       expenses, reimbursements or indemnities then due to the Lenders and the
       issuer(s) of Letters of Credit;

               (v)    fifth, to pay interest due in respect of Swing Line Loans;

               (vi)   sixth, to pay interest due in respect of Loans (other than
       Swing Line Loans) and L/C Obligations;

               (vii)  seventh, to the ratable payment or prepayment of principal
       outstanding on Swing Line Loans;

               (viii) eighth, to the ratable payment or prepayment of principal
       outstanding on Loans (other than Swing Line Loans) and Reimbursement
       Obligations; and

               (ix)   ninth, to the ratable payment of all other Obligations.

Unless otherwise designated (which designation shall only be applicable prior to
the occurrence of a Default) by the Company, all principal payments in respect
of Loans (other than Swing Line Loans) shall be applied first, to repay
outstanding Floating Rate Loans, and then to repay outstanding Eurodollar Rate
Loans with those Eurodollar Rate Loans which have earlier expiring Interest
Periods being repaid prior to those which have later expiring Interest Periods.
The order of priority set forth in this Section 13.3 and the related provisions
of this Agreement are set forth solely to determine the rights and priorities of
the Administrative Agent, the Lenders, the Swing

                                       99

<PAGE>   110

Line Bank and the issuer(s) of Letters of Credit as among themselves. The order
of priority set forth in clauses (iv) through (ix) of this Section 13.3 may at
any time and from time to time be changed by the Required Lenders without
necessity of notice to or consent of or approval by any Borrower, or any other
Person; provided, that the order of priority of payments in respect of Swing
Line Loans may be changed only with the prior written consent of the Swing Line
Bank. The order of priority set forth in clauses (i) through (iii) of this
Section 13.3 may be changed only with the prior written consent of the
Administrative Agent, and, in the case of clause (iii), with the prior written
consent of the Arranger.

       13.4.  Relations Among Lenders.

       (A)    No Action Without Consent. Except with respect to the exercise of
set-off rights of any Lender in accordance with Section 12.1, the proceeds of
which are applied in accordance with this Agreement, and each Lender agrees that
it will not take any action, nor institute any actions or proceedings, against
the Borrowers or any other obligor hereunder or with respect to any Loan
Document, without the prior written consent of the Required Lenders or, as may
be provided in this Agreement or the other Loan Documents, at the direction of
the Administrative Agent.

       (B)    Not Partners; No Liability. The Lenders are not partners or
co-venturers, and no Lender shall be liable for the acts or omissions of, or
(except as otherwise set forth herein in case of the Administrative Agent)
authorized to act for, any other Lender. The Administrative Agent shall have the
exclusive right on behalf of the Lenders to enforce on the payment of the
principal of and interest on any Loan after the date such principal or interest
has become due and payable pursuant to the terms of this Agreement.

ARTICLE XIV:     BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

       14.1.  Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrowers and
the Lenders and their respective successors and assigns, except that (A) other
than in connection with a transaction involving a Subsidiary Borrower which is
permitted pursuant to the terms of this Agreement, no Borrower shall have any
right to assign its rights or obligations under the Loan Documents without the
consent of all of the Lenders, and any such assignment in violation of this
Section 14.1(A) shall be null and void, and (B) any assignment by any Lender
must be made in compliance with Section 14.3 hereof. The parties to this
Agreement acknowledge that clause (B) of this Section 14.1 relates only to
absolute assignments and does not prohibit assignments creating security
interests, including, without limitation, (x) any pledge or assignment by any
Lender of all or any portion of its rights under this Agreement and any Note to
a Federal Reserve Bank or (y) in the case of a Lender which is a fund, any
pledge or assignment of all or any portion of its rights under this Agreement
and any Note to its trustee in support of its obligations to its trustee;
provided, however, that no such pledge or assignment creating a security
interest shall release the transferor Lender from its obligations hereunder
unless and until the parties thereto have complied with the provisions of
Section 14.3. The Administrative Agent may treat each Lender as the owner of the
Loans made by such Lender hereunder for all purposes hereof unless and

                                      100

<PAGE>   111

until such Lender complies with Section 14.3 hereof in the case of an assignment
thereof or, in the case of any other transfer, a written notice of the transfer
is filed with the Administrative Agent. Any assignee or transferee of a Loan,
Commitment, L/C Interest or any other interest of a Lender under the Loan
Documents agrees by acceptance thereof to be bound by all the terms and
provisions of the Loan Documents. Any request, authority or consent of any
Person, who at the time of making such request or giving such authority or
consent is the owner of any Loan, shall be conclusive and binding on any
subsequent owner, transferee or assignee of such Loan.

       14.2.  Participations.

       (A) Permitted Participants; Effect. Subject to the terms set forth in
this Section 14.2, any Lender may, in the ordinary course of its business and in
accordance with applicable law, at any time sell to one or more banks or other
entities ("PARTICIPANTS") participating interests in any Loan owing to such
Lender, the Commitment of such Lender, any L/C Interest of such Lender or any
other interest of such Lender under the Loan Documents on a pro rata or non-pro
rata basis. Notice of such participation to the Company and the Administrative
Agent shall be required prior to any participation becoming effective with
respect to a Participant which is not a Lender, Designated Lender or an
Affiliate thereof. Upon receiving said notice, the Administrative Agent shall
record the participation in the Register it maintains. Moreover, notwithstanding
such recordation, such participation shall not be considered an assignment under
Section 14.3 of this Agreement and such Participant shall not be considered a
Lender. In the event of any such sale by a Lender of participating interests to
a Participant, such Lender's obligations under the Loan Documents shall remain
unchanged, such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations, such Lender shall remain the
owner of all Loans made by it for all purposes under the Loan Documents, all
amounts payable by the applicable Borrower under this Agreement shall be
determined as if such Lender had not sold such participating interests, and the
applicable Borrower and the Administrative Agent shall continue to deal solely
and directly with such Lender in connection with such Lender's rights and
obligations under the Loan Documents except that, for purposes of Article IV
hereof, the Participants shall be entitled to the same rights as if they were
Lenders.

       (B) Voting Rights. Each Lender shall retain the sole right to approve,
without the consent of any Participant, any amendment, modification or waiver of
any provision of the Loan Documents other than any amendment, modification or
waiver which, if the Participant were a Lender hereunder, would require the
consent of such Participant pursuant to the terms of Section 9.2.

       (C) Benefit of Setoff. The Borrowers agree that each Participant shall be
deemed to have the right of setoff provided in Section 13.1 hereof in respect to
its participating interest in amounts owing under the Loan Documents to the same
extent as if the amount of its participating interest were owing directly to it
as a Lender under the Loan Documents, provided that each Lender shall retain the
right of setoff provided in Section 13.1 hereof with respect to the amount of
participating interests sold to each Participant except to the extent such
Participant exercises its right of setoff. The Lenders agree to share with each
Participant, and each Participant, by exercising the right of setoff provided in
Section 13.1 hereof, agrees to share with each Lender,

                                      101

<PAGE>   112

any amount received pursuant to the exercise of its right of setoff, such
amounts to be shared in accordance with Section 13.2 as if each Participant were
a Lender.

       14.3.  Assignments.

       (A) Permitted Assignments. Any Lender (each such assigning Lender under
this Section 14.3 being a "SELLER") may, in accordance with applicable law, at
any time assign to one or more banks or other entities ("PURCHASERS") all or a
portion of its rights and obligations under this Agreement (including, without
limitation, its Commitment, Loans owing to it, its participation interests in
existing Letters of Credit and Swing Line Loans, and its obligation to
participate in additional Letters of Credit and Swing Line Loans) in accordance
with the provisions of this Section 14.3. Each assignment shall be of a
constant, and not a varying, ratable percentage of all of the Seller's rights
and obligations under this Agreement. Such assignment shall be substantially in
the form of Exhibit D hereto and shall not be permitted hereunder unless such
assignment is either for all of such Seller's rights and obligations under the
Loan Documents or, without the prior written consent of the Administrative
Agent, involves loans and commitments in an aggregate amount of at least Five
Million and 00/100 Dollars ($5,000,000) (which minimum amount shall not apply to
any assignment between Lenders, or to an Affiliate of any Lender). The written
consent of the Administrative Agent, and, prior to the occurrence of a Default,
the Company (which consent, in each such case, shall not be unreasonably
withheld or delayed), shall be required prior to an assignment becoming
effective with respect to a Purchaser which is not a Lender or an Affiliate of
such assigning Lender.

       (B) Effect; Effective Date. Upon (i) delivery to the Administrative Agent
of a notice of assignment, substantially in the form attached as Appendix I to
Exhibit D hereto (a "NOTICE OF ASSIGNMENT"), together with any consent required
by Section 14.3(A) hereof, (ii) payment of a Four Thousand and 00/100 Dollar
($4,000) fee by the assignor to the Administrative Agent for processing such
assignment, which fee shall not apply to any assignment from a Lender to an
Affiliate of such Lender, and (iii) the completion of the recording requirements
in Section 14.3(C), such assignment shall become effective on the later of such
date when the requirements in clauses (i), (ii), and (iii) are met or the
effective date specified in such Notice of Assignment. The Notice of Assignment
shall contain a representation by the Purchaser to the effect that none of the
consideration used to make the purchase of the Commitment, Loans and L/C
Obligations under the applicable assignment agreement are "plan assets" as
defined under ERISA and that the rights and interests of the Purchaser in and
under the Loan Documents will not be "plan assets" under ERISA. On and after the
effective date of such assignment, such Purchaser, if not already a Lender,
shall for all purposes be a Lender party to this Agreement and any other Loan
Documents executed by the Lenders and shall have all the rights and obligations
of a Lender under the Loan Documents, to the same extent as if it were an
original party hereto, and no further consent or action by any Borrower, the
Lenders or the Administrative Agent shall be required to release the Seller with
respect to the percentage of the Aggregate Commitment, Loans and Letter of
Credit and Swing Line Loan participations assigned to such Purchaser. Upon the
consummation of any assignment to a Purchaser pursuant to this Section 14.3(B),
the Seller, the Administrative Agent and the Borrowers shall make appropriate
arrangements so that, to the extent notes have been issued to evidence any of
the transferred Loans, replacement notes are issued to such Seller and new notes
or, as appropriate, replacement notes, are issued to such

                                      102

<PAGE>   113

Purchaser, in each case in principal amounts reflecting their Commitments, as
adjusted pursuant to such assignment. Notwithstanding anything to the contrary
herein, no Borrower shall, at any time, be obligated to pay under Section
2.14(E) to any Lender that is a Purchaser, assignee or transferee any sum in
excess of the sum which such Borrower would have been obligated to pay in
respect of such transferred Loan to the Lender that was the Seller, assignor or
transferor had such assignment or transfer not been effected.

       (C) The Register. Notwithstanding anything to the contrary in this
Agreement, each Borrower hereby designates the Administrative Agent, and the
Administrative Agent, hereby accepts such designation, to serve as such
Borrower's contractual representative solely for purposes of this Section
14.3(C). In this connection, the Administrative Agent shall maintain at its
address referred to in Section 15.1 a copy of each assignment delivered to and
accepted by it pursuant to this Section 14.3 and a register (the "REGISTER") for
the recordation of the names and addresses of the Lenders and the Commitment of,
principal amount of and interest on the Loans owing to, each Lender from time to
time and whether such Lender is an original Lender or the assignee of another
Lender pursuant to an assignment under this Section 14.3. The entries in the
Register shall be conclusive and binding for all purposes, absent manifest
error, and the Company and each of its Subsidiaries, the Administrative Agent
and the Lenders may treat each Person whose name is recorded in the Register as
a Lender hereunder for all purposes of this Agreement. The Register shall be
available for inspection by any Borrower or any Lender at any reasonable time
and from time to time upon reasonable prior notice.

       (D)     Designated Lender.

               (i) Subject to the terms and conditions set forth in this Section
       14.3(D), any Lender may from time to time elect to designate an Eligible
       Designee to provide all or any part of the Loans to be made by such
       Lender pursuant to this Agreement; provided that the designation of an
       Eligible Designee by any Lender for purposes of this Section 14.3(D)
       shall be subject to the approval of the Administrative Agent (which
       consent shall not be unreasonably withheld or delayed). Upon the
       execution by the parties to each such designation of an agreement in the
       form of Exhibit L hereto (a "DESIGNATION AGREEMENT") and the acceptance
       thereof by the Administrative Agent, the Eligible Designee shall become a
       Designated Lender for purposes of this Agreement. The Designating Lender
       shall thereafter have the right to permit the Designated Lender to
       provide all or a portion of the Loans to be made by the Designating
       Lender pursuant to the terms of this Agreement and the making of the
       Loans or portion thereof shall satisfy the obligations of the Designating
       Lender to the same extent, and as if, such Loan was made by the
       Designating Lender. As to any Loan made by it, each Designated Lender
       shall have all the rights a Lender making such Loan would have under this
       Agreement and otherwise; provided, (x) that all voting rights under this
       Agreement shall be exercised solely by the Designating Lender, (y) each
       Designating Lender shall remain solely responsible to the other parties
       hereto for its obligations under this Agreement, including the
       obligations of a Lender in respect of Loans made by its Designated Lender
       and (z) no Designated Lender shall be entitled to reimbursement under
       Article IV hereof for any amount which would exceed the amount that would
       have been payable by the Borrowers to the Lender from which the
       Designated Lender obtained any interests hereunder. No

                                      103

<PAGE>   114

       additional Notes shall be required with respect to Loans provided by a
       Designated Lender; provided, however, to the extent any Designated Lender
       shall advance funds, the Designating Lender shall be deemed to hold the
       Notes in its possession as an agent for such Designated Lender to the
       extent of the Loan funded by such Designated Lender. Such Designating
       Lender shall act as administrative agent for its Designated Lender and
       give and receive notices and communications hereunder. Any payments for
       the account of any Designated Lender shall be paid to its Designating
       Lender as administrative agent for such Designated Lender and neither the
       Borrowers nor the Administrative Agent shall be responsible for any
       Designating Lender's application of such payments. In addition, any
       Designated Lender may (1) with notice to, but without the consent of the
       Borrowers or the Administrative Agent, assign all or portions of its
       interests in any Loans to its Designating Lender or to any financial
       institution consented to by the Administrative Agent providing liquidity
       and/or credit facilities to or for the account of such Designated Lender
       and (2) subject to advising any such Person that such information is to
       be treated as confidential in accordance with such Person's customary
       practices for dealing with confidential, non-public information, disclose
       on a confidential basis any non-public information relating to its Loans
       to any rating agency, commercial paper dealer or provider of any
       guarantee, surety or credit or liquidity enhancement to such Designated
       Lender.

               (ii) Each party to this Agreement hereby agrees that it shall not
       institute against, or join any other Person in instituting against any
       Designated Lender any bankruptcy, reorganization, arrangements,
       insolvency or liquidation proceeding or other proceedings under any
       federal or state bankruptcy or similar law for one year and a day after
       the payment in full of all outstanding senior indebtedness of any
       Designated Lender; provided that the Designating Lender for each
       Designated Lender hereby agrees to indemnify, save and hold harmless each
       other party hereto for any loss, cost, damage and expense arising out of
       their inability to institute any such proceeding against such Designated
       Lender. This Section 14.3(D)(ii) shall survive the termination of this
       Agreement.

       14.4. Confidentiality. Subject to Section 14.5, the Administrative Agent
and the Lenders and their respective representatives, consultants and advisors
shall hold all nonpublic information obtained pursuant to the requirements of
this Agreement and identified as such by the Company or any other Borrower in
accordance with such Person's customary procedures for handling confidential
information of this nature and in accordance with safe and sound commercial
lending or investment practices and in any event may make disclosure reasonably
required by a prospective Transferee in connection with the contemplated
participation or assignment or as required or requested by any Governmental
Authority or any securities exchange or similar self-regulatory organization or
representative thereof or pursuant to a regulatory examination or legal process,
or to any direct or indirect contractual counterparty in swap agreements or such
contractual counterparty's professional advisor, and shall (x) use its
commercially reasonable efforts to give prior notice of any such disclosure to
the extent permitted by applicable law, and (y) require any such Transferee to
agree (and require any of its Transferees to agree) to comply with this Section
14.4. In no event shall the Administrative Agent or any Lender be obligated or
required to return any materials furnished by the Company;

                                      104

<PAGE>   115

provided, however, each prospective Transferee shall be required to agree that
if it does not become a participant or assignee it shall return all materials
furnished to it by or on behalf of the Company in connection with this
Agreement.

       14.5. Dissemination of Information. Each Borrower authorizes each Lender
to disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Loan Documents by operation of law (each a "TRANSFEREE") and any
prospective Transferee any and all information in such Lender's possession
concerning the Borrowers and its Subsidiaries; provided that prior to any such
disclosure, such prospective Transferee shall agree to preserve in accordance
with Section 14.4 the confidentiality of any confidential information described
therein.

                             ARTICLE XV:      NOTICES

       15.1. Giving Notice. Except as otherwise permitted by Section 2.13 with
respect to Borrowing/Election Notices, all notices and other communications
provided to any party hereto under this Agreement or any other Loan Documents
shall be in writing or by telex or by facsimile and addressed or delivered to
such party at its address set forth below its signature hereto or at such other
address as may be designated by such party in a notice to the other parties. Any
notice, if mailed and properly addressed with postage prepaid, shall be deemed
given three (3) Business Days after mailed; any notice, if transmitted by telex
or facsimile, shall be deemed given when transmitted (answerback confirmed in
the case of telexes); or any notice, if transmitted by courier, one (1) Business
Day after deposit with a reputable overnight carrier service, with all charges
paid.

       15.2.  Change of Address.  The Borrowers, the Administrative Agent and
any Lender may each change the address for service of notice upon it by a notice
in writing to the other parties hereto.

                         ARTICLE XVI:     COUNTERPARTS

               This Agreement may be executed in any number of counterparts, all
of which taken together shall constitute one agreement, and any of the parties
hereto may execute this Agreement by signing any such counterpart. This
Agreement shall be effective when it has been executed by the Company, the
Administrative Agent and the Lenders and each party has notified the
Administrative Agent by telex or telephone, that it has taken such action.

dated as of _______________, 20 ___.  The parties hereto agree as follows:

herein called the "Credit Agreement") described in Item 1 of Schedule 1 attached
hereto ("Schedule 1"). Capitalized terms used herein and not otherwise defined
herein shall have the meanings attributed to them in the Credit Agreement.

     (2) ASSIGNMENT AND ASSUMPTION. The Assignor hereby sells and assigns to the
Assignee, and the Assignee hereby purchases and assumes from the Assignor, an
interest in and to the Assignor's rights and obligations under the Credit
Agreement and the other Loan Documents, such that after giving effect to such
assignment the Assignee shall have purchased pursuant to this Assignment
Agreement the percentage interest specified in Item 3 of Schedule 1 of all
outstanding rights and obligations under the Credit Agreement and the other Loan
Documents relating to the facilities listed in Item 3 of Schedule 1. The
aggregate Commitment (or Loans, if the applicable Commitment has been
terminated) purchased by the Assignee hereunder is set forth in Item 4 of
Schedule 1.

     (3) EFFECTIVE DATE. The effective date of this Assignment Agreement (the
"Effective Date") shall be the later of the date specified in Item 5 of Schedule
1 or two Business Days (or such shorter period agreed to by the Administrative
Agent) after this Assignment Agreement, together with any consents required

Effective Date.

assigned hereby. The Assignee will promptly remit to the Assignor any interest
on Loans and fees received from the Administrative Agent which relate to the
portion of the Commitment or Loans assigned to the Assignee hereunder for
periods prior to the Effective Date and not previously paid by the Assignee to
the Assignor. In the event that either party hereto receives any payment to
which the other party hereto is entitled under this Assignment

Agreement, then the party receiving such amount shall promptly remit it to the
other party hereto.

beneficial owner of the interest being assigned by it hereunder, (ii) such
interest is free and clear of any adverse claim created by the Assignor and
(iii) the execution and delivery of this Assignment Agreement by the Assignor is

hereunder are made without recourse to the Assignor and that the Assignor makes
no other representation or warranty of any kind to the Assignee. Neither the

                    FORM OF COMPANY'S US COUNSEL'S OPINION(S)

December 1, 2000

Each of the Lenders party
     to the Credit Agreement
     referred to below
Bank One N.A.
     as Administrative Agent

     RE:  CHICAGO BRIDGE & IRON COMPANY N.V.

Ladies and Gentlemen:

     I have acted as United States counsel to Chicago Bridge & Iron Company
N.V., a company incorporated in The Netherlands (the "Company") and each of the
"Domestic Subsidiaries" (as defined below), in connection with the execution and
delivery of the Credit Agreement dated as of December 1, 2000 (the "Credit
Agreement") among the Company, the lenders party thereto (the "Lenders") and
Bank One, NA, as administrative agent for the Lenders (the "Administrative
Agent").

     This opinion is furnished to you pursuant to Section 5.1(5) of the Credit
Agreement. Capitalized terms used herein without definition have the meanings
specified in the Credit Agreement.

     In connection with the opinions expressed herein, I have examined the
following documents:

     (i)   The Credit Agreement;

     (ii)  Each promissory note, if any, executed and delivered  pursuant to
Section 2.12(D) of the Credit Agreement on the date hereof; and

     (iii) The Subsidiary Guarantee executed and delivered on the date hereof by
a Subsidiary Guarantor that is a Domestic Subsidiary (each, a "Domestic
Subsidiary Guarantor").

<PAGE>   136
Page 2
December 1, 2000

     The documents referred to in clauses (i) through (iii) above are
collectively referred to herein as the "Loan Documents." The Domestic Subsidiary
Borrowers executing and delivering the Credit Agreement on the date hereof and
the Domestic Subsidiary Guarantors executing and delivering Subsidiary
Guarantees on the date hereof are set forth on Annex A hereto and are
collectively referred to herein as the "Domestic Subsidiaries."

     In rendering this opinion to you, I have assumed, without inquiry:

     (a) (i) the genuineness of all signatures other than those on behalf of the
Domestic Subsidiaries on original copies of the Loan Documents; (ii) the
conformity to the original documents of all documents submitted to me as copies
and the authenticity of all documents submitted to me as originals; (iii) the
due authorization, execution and delivery of the Loan Documents by each of the
parties thereto other than the Company (solely with respect to execution and
delivery) and Domestic Subsidiaries and (iv) the validity and enforceability of
the Loan Documents against each of the parties thereto other than the Company
and the Domestic Subsidiaries;

     (b) that the execution, delivery and performance of the Loan Documents by
each party thereto do not conflict with or constitute a violation of any law or
governmental rule or regulation of (i) the State of Delaware other than the
General Corporation Law of the State of Delaware (the "DGCL") or (ii) any other
jurisdiction other than the United States of America and the State of Illinois;

     (c) that the execution, delivery and performance of the Loan Documents by
each party thereto other than, with respect to clauses (ii) and (iii) below, as
applicable to the Company and with respect to clauses (i), (ii) and (iii) for
each of the Domestic Subsidiaries) do not breach, conflict with or constitute a
violation of or default under (i) the certificate of association or
incorporation, by-laws or any other charter or governing document of such party;
(ii) any agreement, instrument or document to which any such party was, or is, a
party or by which any such party or any of its properties was, or is, bound or
(iii) any order, judgment or decree to which any such party was, or is, bound or
subject or by which any of its properties was, or is, bound; and

     (d) that any consideration contemplated to be given on the Closing Date by
any party in any of the Loan Documents was given on the Closing Date.

     Based upon the foregoing assumptions and subject to the limitations,
qualifications and exceptions hereinafter set forth, I am of the opinion that:

<PAGE>   137
Page 3
December 1, 2000

     1. Each Domestic Subsidiary that is a Borrower on the date hereof or a
Guarantor on the date hereof (a) is a corporation duly organized and validly
existing under the laws of the jurisdiction of its organization, (b) has all
requisite corporate power and authority to own its property and assets and to
carry on its business as now conducted and as proposed to be conducted, (c) is
duly qualified as a foreign corporation to transact business and is in good
standing in its jurisdiction of incorporation and each jurisdiction where such
qualification is required, except where the failure to be so qualified or be in
good standing could not reasonably be expected to result in a Material Adverse
Effect, and (d) has the corporate power and authority to execute, deliver and
perform its obligations under each Loan Document to which it is a party
including to borrow in accordance with the Credit Agreement.

     2. The execution, delivery and performance of each Loan Document by the
Company and each Domestic Subsidiary that is a Borrower on the date hereof or a
Guarantor on the date hereof and the borrowings thereunder to be made on the
date hereof by each Domestic Borrowing Subsidiary (a) have been duly authorized
by all requisite corporate action of such Domestic Subsidiary and (b) with
respect to the following clauses (i)(B), (i)(C), (ii) and (iii) as applicable to
the Company and for all of the following clauses (i), (ii) and (iii) as
applicable to the domestic Subsidiaries will not (i) violate (A) any provision
of the certificate of incorporation or by-laws of such Domestic Subsidiary, (B)
any applicable federal or Illinois State law, statute, rule or regulation, the
DGCL or any order of any federal or Illinois State Governmental Authority with
jurisdiction over the Company or any such Domestic Subsidiary or its properties
or the Chancery Court, appellate courts or Secretary of State of the State of
Delaware or (C) any provision of any indenture or other material agreement or
instrument known to me to which the Company or any such Domestic Subsidiary is a
party or by which it or any of its property may be bound, (ii) result in a
default under any such indenture, agreement or other instrument or (iii) result
in the creation or imposition of any Lien (other than Permitted Liens) upon or
with respect to any property or assets now owned or hereafter acquired by the
Company or any such Domestic Subsidiary except, in the case of clauses (i)
through (iii) above, for any of the foregoing that could not reasonably be
expected to result in a Material Adverse Effect or materially and adversely to
affect the rights or interests of the Lenders under the Loan Documents.

     3. Each Loan Document has been duly executed and delivered by the Company
and each Domestic Subsidiary party thereto, and each such Loan Document
constitutes the legal, valid and binding obligation of each such Domestic
Subsidiary, enforceable against the Company and such Domestic Subsidiary in
accordance with its terms subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium, or other laws affecting
creditors' rights generally and subject to general principles of equity,
regardless of whether considered in a proceeding in equity or at law.

<PAGE>   138
Page 4
December 1, 2000

     4. No consent or approval of, registration or filing with, or any other
action by any federal or Illinois State Governmental Authority with jurisdiction
over the Company or the Domestic Subsidiaries or the Chancery Court, or
appellate courts or Secretary of State of the State of Delaware is or will be
required in connection with the execution, delivery or performance of the Loan
Documents by the Company and the Domestic Subsidiaries party thereto or the
consummation of the transactions thereby, other than any such authorizations and
approvals as have already been obtained and are in full force and effect
according to federal or Illinois law, or the DGCL.

     5. To the best of my knowledge, there are no pending or threatened actions,
suits or proceedings at law or in equity or by or before any federal, Illinois
or Delaware Governmental Authority against or affecting the Company or any
Domestic Subsidiary or any business, property or rights of any such person that
involve any Loan Documents or the transactions contemplated thereby.

     6. None of the Company or any of the Domestic Subsidiaries is an investment
company or a company controlled by an investment company within the meaning of
the Investment Company Act of 1940.

     7. None of the Company or any of the Domestic Subsidiaries is a holding
company or a subsidiary company of a holding company within the meaning of the
Public Utility Holding Company Act of 1935.

     8. The application of the proceeds thereof by the Borrowers pursuant to the
terms of the Credit Agreement will not violate Regulation T, U or X of the Board
of Governors of the Federal Reserve System.

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

     A. The enforceability of the Loan Documents is subject to (i) applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer,
moratorium or other laws affecting creditor's rights generally and (ii) general
principles of equity (regardless of whether considered in a proceeding in equity
or at law).

<PAGE>   139
Page 5
December 1, 2000

     B. I express no opinion as to the Lenders' right to collect any payment to
the extent that such payment constitutes a penalty, forfeiture or late charge.

     C. I express no opinion as to the applicability of Section 548 of the
Federal Bankruptcy Code or of any provisions of any state fraudulent conveyance
statute or law to the transactions contemplated by the Loan Documents.

     The foregoing opinions are limited to matters involving the federal laws of
the United States, the law of the State of Illinois and the DGCL, and I do not
express any opinion as to the laws of any other jurisdiction.

     This opinion is rendered solely to, and is intended solely for the benefit
of, the Administrative Agent and the Lenders, in connection with the
transactions contemplated in the Loan Documents. This opinion may not be relied
upon by the Administrative Agent or any of the Lenders or any of their
respective successors and assigns for any other purpose, or by any other person,
firm or corporation for any purpose, in each case without my prior written
consent.

                                   Very truly yours,

                                   Robert H. Wolfe

3.6  A faxed copy of a confirmation from Robert H. Wolfe in his stated capacity
     as the secretary of the Company's supervisory board dated November 27, 2000

     directions pursuant to article 17.2 of the Company's articles of
     association which affect the written resolution referred to in paragraph

     on the date of this opinion:

3.10 Confirmation from the Chamber of Commerce that the trade register extracts

     respect of certain matters resolved in the resolution referred to in
     paragraph 3.9).

3.11 Confirmation from the office of the bankruptcy division
     (faillissementsgriffie) of the Amsterdam district court that the Company is
     not registered as having been declared bankrupt or granted suspension of
     payments.

     My examination has been limited to the text of the documents and I have not
     investigated the meaning and effect of any document governed by a law other
     than Dutch law under that other law.

4    ASSUMPTIONS

     For the purpose of this opinion, I have made the following assumptions:

4.1  All copy documents conform to the originals and all originals are genuine
     and complete.

4.2  Each signature is the genuine signature of the individual concerned.

4.3  The extract from the minutes referred to in paragraph 3 is a true record of
     the proceedings described in it in a duly convened, constituted and quorate
     meeting and the resolutions set out in those minutes were validly passed
     and remain in full force and effect without modification. The written
     resolutions referred to in paragraph 3 remain in full force and effect
     without modification. The confirmation referred to in paragraph 3 is true.

4.4  The Credit Agreement has been or will have been entered into in the form
     referred to in paragraph 3.

4.5  The Credit Agreement is within the capacity and powers of, and has been or
     will have been validly authorised and signed by, each party other than the
     Company.

                                       4
<PAGE>   145

4.6  The Credit Agreement has been or will have been signed on behalf of the
     Company by Mr. G.M. Glenn as managing director of the Managing Director.

4.8  When validly signed by all the parties, the Credit Agreement (including the
     submission to the jurisdiction of the Illinois courts and the federal
     courts located in Illinois pursuant to clause 11.13 of the Credit
     Agreement) is valid, binding and enforceable on each party under the law of
     the State of Illinois by which it is expressed to be governed.

4.9  The Company does not qualify as a credit institution (kredietinstelling)
     within the meaning of the 1992 Act on the Supervision of the Credit System
     (Wet toezicht kredietwezen 1992).

4.10 All (promissory) notes or other securities issued pursuant to or in
     connection with the Credit Agreement have a denomination of at least NLG
     100,000 (or its foreign currency equivalent).

4.11 Mr. J.R. Edmonds is managing director of the Managing Director.

4.12 There are no dealings between the parties which affect the Credit
     Agreement.

5    OPINION

     Based on the documents and confirmations referred to and the assumptions in
     paragraphs 3 and 4 and subject to the qualifications in paragraph 6 and to
     any matters not disclosed to me, I am of the following opinion:

5.1  The Company has been incorporated and is existing as a limited liability
     company (naamloze vennootschap) under Dutch law.

5.2  The Company has the corporate power to enter into and perform the Credit
     Agreement.

5.3  The Company has taken all necessary corporate action to authorise its entry
     into and performance of the Credit Agreement.

5.4  The Credit Agreement has been validly signed by the Company.

5.5  Under Dutch law there are no governmental or regulatory consents, approvals
     or authorisations required by the Company for its entry into and
     performance of the Credit Agreement.

                                       5
<PAGE>   146

5.6  Under Dutch law there are no registration, filing or similar formalities
     required to ensure the validity, binding effect and enforceability against
     the Company and the admissibility in evidence of the Credit Agreement.

5.7  The entry into and performance of the Credit Agreement by the Company do
     not violate Dutch law or the Company's articles of association.

5.8  Under Dutch law the choice of the law of the State of Illinois as the
     governing law of the Credit Agreement is recognised and accordingly the law
     of the State of Illinois law governs the validity, binding effect and
     enforceability against the Company of the Credit Agreement.

5.9  A judgment rendered by an Illinois court or federal court located in
     Illinois will not be recognised and enforced by the Dutch courts. However,
     if a person has obtained a final and conclusive judgment for the payment of
     money rendered by an Illinois court or federal court located in Illinois
     (the "FOREIGN COURT") which is enforceable in Illinois (the "FOREIGN
     JUDGMENT") and files his claim with the competent Dutch court, the Dutch
     court will generally give binding effect to the foreign judgment insofar as
     it finds that the jurisdiction of the foreign court has been based on
     grounds which are internationally acceptable and that proper legal
     procedures have been observed and unless the foreign judgment contravenes
     Dutch public policy.

5.10 In matters which pursuant to clause 11.13 of the Credit Agreement must be
     settled by the courts in Illinois a Dutch court will not accept
     jurisdiction, subject to exceptions similar to those set out in the
     Brussels Convention on Jurisdiction and the Enforcement of Judgements in
     Civil and Commercial Matters 1968 (as amended).

6    QUALIFICATIONS

     This opinion is subject to the following qualifications:

6.1  This opinion is subject to any limitations arising from bankruptcy,
     insolvency, liquidation, moratorium, reorganisation and other laws of
     general application relating to or affecting the rights of creditors.

6.2  Under Dutch law, notwithstanding the recognition of the law of the State of
     Illinois as the governing law of the Credit Agreement:

     -    effect may be given to the law of another jurisdiction with which the
          situation has a close connection, insofar as, under the law of that
          jurisdiction, that law is mandatory irrespective of the governing law
          of the Credit Agreement;

     -    Dutch law will be applied insofar as it is mandatory irrespective of
          the governing law of the Credit Agreement;

                                       6
<PAGE>   147

     -    the application of the law of the State of Illinois may be refused if
          it is manifestly incompatible with Dutch public policy;

     -    regard will be had to the law of the jurisdiction in which performance
          takes place in relation to the manner of performance and the steps to
          be taken in the event of defective performance.

6.3  The enforcement in a Dutch court of the Credit Agreement and of foreign
     judgments is subject to Dutch rules of civil procedure.

6.4  No opinion is rendered in respect of the authority of the Addressees to
     grant credit in the Netherlands.

6.5  No opinion is rendered in respect of the validity of any assignment or any
     sale of a participation by a Lender (as defined in the Credit Agreement)
     nor in respect of any undivided interest and participation in any loan
     pursuant to the Credit Agreement.

6.6  Under Dutch law, a legal act (rechtshandeling) performed by a legal entity
     (including (without limitation) an agreement pursuant to which it agrees to
     guarantee or guarantees the obligations of a third party) may be nullified
     by (i) any of its creditors, or (ii) its trustee in bankruptcy, if (a) it
     performed the act without an obligation to do so (onverplicht), (b) the
     creditor concerned or (in the case of its bankruptcy) any creditor was
     prejudiced as a consequence of the act, and (c) at the time the act was
     performed both it and (unless the act was for no consideration (om niet))
     the party with or towards which it acted, knew or should have known that
     one or more of its creditors (present or future) would be prejudiced. In
     addition, in the case of a legal entity's bankruptcy, its trustee in
     bankruptcy may nullify its performance of any due and payable obligation
     (opeisbare schuld) if (x) the recipient of the performance knew that a
     request for bankruptcy had been filed, or (y) the performance of the
     obligation was the result of consultation between it and the recipient with
     a view to give preference to the latter over the legal entity's creditors.

6.7  If a Dutch company performs a legal act (rechtshandeling) (including
     (without limitation) an agreement pursuant to which it guarantees the
     performance of the obligations of a third party which is not a wholly owned
     direct or indirect subsidiary of such company and any other legal act
     having a similar effect and including (without limitation) an agreement
     pursuant to which it agrees to provide or provides security for its
     obligations under such agreement or other act) and that act is not in the
     company's corporate interest, it may (i) exceed its corporate power, (ii)
     violate its articles of association and (iii) not be valid, binding and
     enforceable against it.

6.8  Pursuant to Section 46a of the Dutch 1995 Securities Act (Wet toezicht
     effectenverkeer 1995, the "SECURITIES ACT") it is prohibited to disclose
     the information referred to in Section 7.1 of the Credit Agreement to the
     extent it consists of inside information (voorwetenschap) within the
     meaning of Section 46 of the Securities Act.

                                       7
<PAGE>   148

6.9  Under Dutch law, a power of attorney can be made irrevocable only (i)
     insofar as it has been granted for the purpose of performing a legal act in
     the interest of the authorised person or a third party and (ii) subject to
     any amendments made or limitations imposed by the courts on serious grounds
     (gewichtige redenen).

6.10 The trade register extracts referred to in paragraph 3 do not provide
     conclusive evidence that the facts set out in it are correct. However,
     under the 1996 Trade Register Act (Handelsregisterwet 1996), subject to
     limited exceptions, the Company cannot invoke the incorrectness or
     incompleteness of its trade register registration against third parties who
     were unaware of it.

6.11 The confirmation from the office of the bankruptcy division referred to in
     paragraph 3 does not provide conclusive evidence that the Company has not
     been declared bankrupt or granted suspension of payments.

6.12 I do not express any opinion as to any taxation matters.

Agreements, including, without limitation, (i) the principal of and interest on

Borrower or any of their Affiliates, as applicable, to pay punctually any such
amount, each of the Guarantors agrees that it shall forthwith on demand pay such
amount at the place and in the manner specified in the Credit Agreement, any
Designated Hedging Agreement or the relevant Loan Document, as the case may be.
Each of the Guarantors hereby agrees that this Guaranty is an absolute,
irrevocable and unconditional guaranty of payment and is not a guaranty of
collection.
XII. Guaranty Unconditional. The obligations of each of the Guarantors
hereunder shall be unconditional and absolute and, without limiting the
generality of the foregoing, shall not be released, discharged or otherwise
affected by:
     (1)  any extension, renewal, settlement, indulgence, compromise, waiver or
          release of or with respect to the Guaranteed Obligations or any part

          to the Guaranteed Obligations or any part thereof, or any
          nonperfection or invalidity of any direct or indirect security for the
          Guaranteed Obligations;

     (4)  any change in the corporate, partnership or other existence, structure
          or ownership of any Borrower or any other guarantor of any of the
          Guaranteed Obligations, or any insolvency, bankruptcy, reorganization
          or other similar proceeding affecting any Borrower or any other
          guarantor of the Guaranteed Obligations, or any of their respective

          Agent, any holder of Obligations or any other Person, whether in
          connection herewith or in connection with any unrelated transactions,
          provided that nothing herein shall prevent the assertion of any such
          claim by separate suit or compulsory counterclaim;

                                       8
<PAGE>   166

     (6)  the enforceability or validity of the Guaranteed Obligations or any
          part thereof or the genuineness, enforceability or validity of any
          agreement relating thereto or any other invalidity or unenforceability
          relating to or against any Borrower or any other guarantor of any of
          the Guaranteed Obligations, for any reason related to the Credit
          Agreement, any Designated Hedging Agreement, any other Loan Document,
          or any provision of applicable law or regulation purporting to
          prohibit the payment by any Borrower or any other guarantor of the
          Guaranteed Obligations, of any of the Guaranteed Obligations;

     (7)  the failure of the Administrative Agent to take any steps to perfect

          Guaranteed Obligations;

     (11) the failure of any other Guarantor to sign or become party to this

          any other guarantor of the Guaranteed Obligations, the Administrative
          Agent, any holder of Obligations or any other Person or any other
          circumstance whatsoever which might, but for the provisions of this
          Section 4, constitute a legal or equitable discharge of any
          Guarantor's obligations hereunder.

XIII.  Discharge Only Upon Payment In Full: Reinstatement In Certain
Circumstances. Each of the Guarantors' obligations hereunder shall remain in
full force and effect until all Guaranteed Obligations shall have been paid in
full in cash and the Commitments and all Letters of Credit issued under the
Credit Agreement shall have terminated or expired. If at any time any payment of
the principal of or interest on any Advance or Reimbursement Obligation or any
other amount payable by the Borrower or any other party under the Credit
Agreement, any Designated Hedging Agreement or any other Loan Document is
rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy or reorganization of any Borrower or otherwise, each of the
Guarantors' obligations hereunder with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

                                       9
<PAGE>   167

XIV. General Waivers. Each of the Guarantors irrevocably waives acceptance
hereof, presentment, demand or action on delinquency, protest, the benefit of
any statutes of limitations and, to the fullest extent permitted by law, any
notice not provided for herein, as well as any requirement that at any time any
action be taken by any Person against any Borrower, any other guarantor of the
Guaranteed Obligations, or any other Person.
XV.  Subordination of Subrogation; Subordination of Intercompany Indebtedness.
     (1)  Subordination of Subrogation. Until the Guaranteed Obligations have
          been indefeasibly paid in full in cash, the Guarantors (i) shall have
          no right of subrogation with respect to such Guaranteed Obligations
          and (ii) waive any right to enforce any remedy which the Issuing
          Banks, holders of the Guaranteed Obligations or the Administrative
          Agent now have or may hereafter have against any Borrower, any
          endorser or any guarantor of all or any part of the Obligations or any
          other Person, and the Guarantors waive any benefit of, and any right
          to participate in, any security or collateral given to the holders of
          Guaranteed Obligations and the Administrative Agent to secure the
          payment or performance of all or any part of the Guaranteed
          Obligations or any other liability of the Borrowers to the holders of
          the Guaranteed Obligations. Should any Guarantor have the right,
          notwithstanding the foregoing, to exercise its subrogation rights,
          each Guarantor hereby expressly and irrevocably (A) subordinates any
          and all rights at law or in equity to subrogation, reimbursement,
          exoneration, contribution, indemnification or set off that the
          Guarantor may have to the indefeasible payment in full in cash of the
          Guaranteed Obligations and (B) waives any and all defenses available
          to a surety, guarantor or accommodation co-obligor until the
          Guaranteed Obligations are indefeasibly paid in full in cash. Each
          Guarantor acknowledges and agrees that this subordination is intended
          to benefit the Administrative Agent and the holders of the Guaranteed
          Obligations and shall not limit or otherwise affect such Guarantor's
          liability hereunder or the enforceability of this Guaranty, and that
          the Administrative Agent, the holders of the Guaranteed Obligations
          and their respective successors and assigns are intended third party
          beneficiaries of the waivers and agreements set forth in this Section
          7(a).

     (2)  Subordination of Intercompany Indebtedness. Each Guarantor agrees that
          any and all claims of such Guarantor against either any Borrower or
          any other Guarantor hereunder (each an "Obligor") with respect to any
          "Intercompany Indebtedness" (as hereinafter defined), any endorser,
          obligor or any other guarantor of all or any part of

                                       10
<PAGE>   168

          the Guaranteed Obligations, or against any of its properties shall be
          subordinate and subject in right of payment to the prior payment, in
          full and in cash, of all Guaranteed Obligations. Notwithstanding any
          right of any Guarantor to ask, demand, sue for, take or receive any
          payment from any Obligor, all rights, liens and security interests of
          such Guarantor, whether now or hereafter arising and howsoever
          existing, in any assets of any other Obligor shall be and are
          subordinated to the rights of the holders of the Guaranteed
          Obligations and the Administrative Agent in those assets. No Guarantor
          shall have any right to possession of any such asset or to foreclose
          upon any such asset, whether by judicial action or otherwise, unless
          and until all of the Guaranteed Obligations (other than contingent
          indemnity obligations) shall have been fully paid and satisfied (in
          cash) and all financing arrangements pursuant to any Loan Document or
          any Designated Hedging Agreement have been terminated. If all or any
          part of the assets of any Obligor, or the proceeds thereof, are
          subject to any distribution, division or application to the creditors
          of such Obligor, whether partial or complete, voluntary or
          involuntary, and whether by reason of liquidation, bankruptcy,
          arrangement, receivership, assignment for the benefit of creditors or
          any other action or proceeding, or if the business of any such Obligor
          is dissolved or if substantially all of the assets of any such Obligor
          are sold, then, and in any such event (such events being herein
          referred to as an "Insolvency Event"), any payment or distribution of
          any kind or character, either in cash, securities or other property,
          which shall be payable or deliverable upon or with respect to any
          indebtedness of any Obligor to any Guarantor ("Intercompany
          Indebtedness") shall be paid or delivered directly to the
          Administrative Agent for application on any of the Guaranteed
          Obligations, due or to become due, until such Guaranteed Obligations
          (other than contingent indemnity obligations) shall have first been
          fully paid and satisfied (in cash). Should any payment, distribution,
          security or instrument or proceeds thereof be received by the
          applicable Guarantor upon or with respect to the Intercompany
          Indebtedness after any Insolvency Event and prior to the satisfaction
          of all of the Guaranteed Obligations (other than contingent indemnity
          obligations) and the termination of all financing arrangements
          pursuant to any Loan Document and/or Designated Hedging Agreements,
          such Guarantor shall receive and hold the same in trust, as trustee,
          for the benefit

                                       11
<PAGE>   169

          of the holders of the Guaranteed Obligations and shall forthwith
          deliver the same to the Administrative Agent, for the benefit of such
          Persons, in precisely the form received (except for the endorsement or
          assignment of the Guarantor where necessary), for application to any
          of the Guaranteed Obligations, due or not due, and, until so
          delivered, the same shall be held in trust by the Guarantor as the
          property of the holders of the Guaranteed Obligations. If any such
          Guarantor fails to make any such endorsement or assignment to the
          Administrative Agent, the Administrative Agent or any of its officers
          or employees is irrevocably authorized to make the same. Each
          Guarantor agrees that until the Guaranteed Obligations (other than the
          contingent indemnity obligations) have been paid in full (in cash) and
          satisfied and all financing arrangements pursuant to any Loan Document
          or any Designated Hedging Agreement have been terminated, no Guarantor
          will assign or transfer to any Person (other than the Administrative
          Agent) any claim any such Guarantor has or may have against any
          Obligor.

XVI.      Contribution with Respect to Guaranteed Obligations.

          (1)  To the extent that any Guarantor shall make a payment under this
               Guaranty (a "Guarantor Payment") which, taking into account all
               other Guarantor Payments then previously or concurrently made by
               any other Guarantor, exceeds the amount which otherwise would
               have been paid by or attributable to such Guarantor if each
               Guarantor had paid the aggregate Guaranteed Obligations satisfied
               by such Guarantor Payment in the same proportion as such
               Guarantor's "Allocable Amount" (as defined below) (as determined
               immediately prior to such Guarantor Payment) bore to the
               aggregate Allocable Amounts of each of the Guarantors as
               determined immediately prior to the making of such Guarantor
               Payment, then, following indefeasible payment in full in cash of
               the Guaranteed Obligations and termination of the Credit
               Agreement and the Designated Hedging Agreements, such Guarantor
               shall be entitled to receive contribution and indemnification
               payments from, and be reimbursed by, each other Guarantor for the
               amount of such excess, pro rata based upon their respective
               Allocable Amounts in effect immediately prior to such Guarantor
               Payment.

          (2)  As of any date of determination, the "Allocable Amount" of any
               Guarantor shall be equal to the maximum amount of the claim which
               could then be recovered from such

                                       12
<PAGE>   170

          Guarantor under this Guaranty without rendering such claim voidable or
          avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or
          under any applicable state Uniform Fraudulent Transfer Act, Uniform
          Fraudulent Conveyance Act or similar statute or common law.

     (3)  This Section 8 is intended only to define the relative rights of the
          Guarantors, and nothing set forth in this Section 8 is intended to or
          shall impair the obligations of the Guarantors, jointly and severally,
          to pay any amounts as and when the same shall become due and payable
          in accordance with the terms of this Guaranty.

     (4)  The parties hereto acknowledge that the rights of contribution and
          indemnification hereunder shall constitute assets of the Guarantor or
          Guarantors to which such contribution and indemnification is owing.

     (5)  The rights of the indemnifying Guarantors against other Guarantors
          under this Section 8 shall be exercisable upon the full and
          indefeasible payment of the Guaranteed Obligations in cash and the
          termination of the Credit Agreement and the Designated Hedging
          Agreements.

XVII. Stay of Acceleration. If acceleration of the time for payment of any
amount payable by any Borrower under the Credit Agreement, any counterparty to
any Designated Hedging Agreement or any other Loan Document is stayed upon the
insolvency, bankruptcy or reorganization of any Borrower or any of their
Affiliates, all such amounts otherwise subject to acceleration under the terms
of the Credit Agreement, any Designated Hedging Agreement or any other Loan
Document shall nonetheless be payable by each of the Guarantors hereunder
forthwith on demand by the Administrative Agent. XVIII. Notices. All notices,
requests and other communications to any party hereunder shall be given in the
manner prescribed in Article XV of the Credit Agreement with respect to the
Administrative Agent at its notice address therein and with respect to any
Guarantor at the address set forth below or such other address or telecopy

               thereof by a Governmental Authority but excluding, in the case of
               each Lender and the Administrative Agent, such taxes (including
               income taxes, franchise taxes and branch profit taxes) as are
               imposed on or measured by such Lender's or the Administrative
               Agent's, as the case may be, net income by the United States of
               America or any Governmental Authority of the jurisdiction under
               the laws of which such Lender or the Administrative Agent, as the
               case may be, is organized (all such non-excluded taxes, levies,
               imposts, deductions, charges, withholdings, and liabilities which
               the Administrative Agent or a Lender determines to be applicable
               to this Guaranty, the other Loan Documents, the Revolving Loan
               Commitments, the Loans or the Letters of Credit being hereinafter
               referred to as "Taxes"). If any Guarantor shall be required by
               law to deduct or withhold any Taxes from or in respect of any sum
               payable hereunder to any holder of Obligations, (i) the sum
               payable shall be increased as may be necessary so that after
               making all required deductions or withholdings (including
               deductions applicable to additional sums payable under this
               Section 16(A)) such Lender or 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 applicable Guarantor shall make such deductions or
               withholdings, and (iii) the applicable Guarantor shall pay the
               full amount deducted or withheld to the relevant taxation
               authority or other authority in accordance with applicable law.
               If a withholding tax of the United States of America or any other
               Governmental Authority shall be or become applicable (y) after
               the date of this Guaranty, to such payments by the applicable
               Guarantor made to the Lending Installation or any other office
               that a Lender may claim as its Lending Installation, or (z) after
               such Lender's selection and designation of any other Lending
               Installation, to such payments made to such other Lending
               Installation, such Lender shall use reasonable efforts to make,
               fund and maintain the affected Loans through another Lending
               Installation of such Lender in another jurisdiction so as to
               reduce the applicable Guarantor's liability hereunder, if the
               making, funding or maintenance of such Loans through such other
               Lending Installation of such Lender does not, in the judgment of
               such Lender, otherwise adversely affect such Loans, or
               obligations under the Commitments of such Lender.

          (2)  In addition, each of the Guarantors agrees to pay any present or
               future stamp or documentary taxes or any other excise or property
               taxes, charges, or similar levies which arise from any payment
               made hereunder, or from the execution, delivery or registration
               of, or otherwise with respect to, this Guaranty, the other Loan
               Documents, the Commitments, the Loans or the Letters of Credit
               (hereinafter referred to as "Other Taxes").

          (3)  Subject to the exceptions in the Credit Agreement, each of the
               Guarantors indemnifies each Lender and the Administrative Agent
               for the full amount of Taxes and Other Taxes (including, without
               limitation, any Taxes or Other Taxes imposed by any Governmental
               Authority on amounts payable under this Section 16(A)) paid by
               such Lender or the Administrative Agent (as the case may be) and
               any liability (including penalties, interest, and expenses)
               arising therefrom or with respect thereto, whether or not such
               Taxes or Other Taxes were correctly or legally asserted. This
               indemnification shall be made within thirty (30) days after the
               date such Lender or the Administrative Agent (as the case may be)
               makes written demand therefor. If the Taxes or Other Taxes with
               respect to which any Guarantor has made either a direct payment
               to the taxation or other authority or an indemnification payment
               hereunder are subsequently refunded to any Lender, such Lender
               will return to the applicable Guarantor an amount equal to the
               lesser of the indemnification payment or the refunded amount. A
               certificate as to any additional amount payable to any Lender or
               the Administrative Agent under this Section 16(A) submitted to
               the applicable Guarantor and the Administrative Agent (if a
               Lender is so submitting) by such Lender or the Administrative
               Agent shall show in reasonable detail the amount payable and the
               calculations used to determine such amount and shall, absent
               manifest error, be deemed presumptively correct. With respect to
               such deduction or withholding for or on account of any Taxes and
               to confirm that all such Taxes have been paid to the appropriate
               Governmental Authorities, the applicable Guarantor or Guarantors
               shall promptly (and in any event not later than thirty (30) days
               after receipt) furnish to each Lender and the Administrative
               Agent such certificates, receipts and other documents as may be
               required (in the reasonable judgment of such Lender or the
               Administrative Agent) to establish any tax credit to which such
               Lender or the Administrative Agent may be entitled.

          (4)  Within thirty (30) days after the date of any payment of Taxes or
               Other Taxes by any Guarantor, the applicable Guarantor shall
               furnish to the Administrative Agent the original or a certified
               copy of a receipt evidencing payment thereof.

          (5)  Without prejudice to the survival of any other agreement of the
               Guarantors hereunder, the agreements and obligations of the
               Guarantors contained in this Section 16(A) shall survive the
               payment in full of all Guaranteed Obligations and the termination
               of this Guaranty.

                                       17
<PAGE>   175

B.     Expenses of Enforcement, Etc. Subject to the terms of the Credit
       Agreement, after the occurrence of a Default under the Credit
       Agreement, the Lenders shall have the right at any time to direct the
       Administrative Agent to commence enforcement proceedings with respect
       to the Guaranteed Obligations. The Guarantors agree to reimburse the
       Administrative Agent and the holders of Obligations for any costs and
       out-of-pocket expenses (including reasonable attorneys' fees and time
       charges of attorneys for the Administrative Agent and the holders of
       Obligations, which attorneys may be employees of the Administrative
       Agent or the holders of Obligations) paid or incurred by the
       Administrative Agent or any holders of Obligation in connection with
       the collection and enforcement of amounts due under the Loan
       Documents, including without limitation this Guaranty. The
       Administrative Agent agrees to distribute payments received from any
       of the Guarantors hereunder to the holders of Obligations on a pro
       rata basis for application in accordance with the terms of the Credit
       Agreement.

XXV.   Judgment Currency. If, for the purposes of obtaining judgment in any
court, it is necessary to convert a sum due from any Guarantor hereunder in the
currency expressed to be payable herein (the "specified currency") into another
currency, the parties hereto agree, to the fullest extent that they may
effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures the Administrative Agent could
purchase the specified currency with such other currency at the Administrative
Agent's main office in Chicago, Illinois on the Business Day preceding that on
which the final, non-appealable judgment is given. The obligations of each
Guarantor in respect of any sum due to the Administrative Agent, for itself and
the other Lenders, hereunder or under any other Loan Document shall,
notwithstanding any judgment in a currency other than the specified currency, be
discharged only to the extent that on the Business Day following receipt by the
Administrative Agent of any sum adjudged to be so due in such other currency the
Administrative Agent may in accordance with normal, reasonable banking
procedures purchase the specified currency with such other currency. If the
amount of the specified currency so purchased is less than the sum originally
due to the Administrative Agent, on behalf of itself or any Lender, in the
specified currency, each Guarantor agrees, to the fullest extent that it may
effectively do so, as a separate obligation and notwithstanding any such
judgment, to indemnify the Administrative Agent against such loss.
XXVI.  Setoff.  At any time after all or any part of the Guaranteed Obligations
have become due and payable (by acceleration or otherwise), each holder of
Obligations and the Administrative Agent may, without notice to any Guarantor
and regardless of the acceptance of any security or collateral for the payment
hereof, appropriate and apply toward the payment of all or any part of the
Guaranteed Obligations (i) any indebtedness due or to become due from such
holder of Obligations or the Administrative Agent to any Guarantor, and (ii) any
moneys, credits or other property belonging to any Guarantor, at any time held
by or coming into the possession of such holder of Obligations or the
Administrative Agent or any of their respective affiliates.
XXVII. Financial Information. Each Guarantor hereby assumes responsibility for
keeping itself informed of the financial condition of the Borrowers and any and
all endorsers and/or other Guarantors of all or any part of the Guaranteed
Obligations, and of all other circumstances bearing upon the risk of nonpayment
of the Guaranteed Obligations, or any part thereof, that diligent inquiry would
reveal, and each Guarantor hereby agrees that none of the holders of Obligations
or the Administrative Agent shall have any duty to advise such Guarantor of
information known to any of them regarding such condition or any such
circumstances. In the

                                       18
<PAGE>   176

event any holder of Obligations or the Administrative Agent, in its sole
discretion, undertakes at any time or from time to time to provide any such
information to a Guarantor, such holder of Obligations or the Administrative
Agent shall be under no obligation (i) to undertake any investigation not a part
of its regular business routine, (ii) to disclose any information which such
holder of Obligations or the Administrative Agent, pursuant to accepted or
reasonable commercial finance or banking practices, wishes to maintain
confidential or (iii) to make any other or future disclosures of such
information or any other information to such Guarantor.
XXVIII. Severability.  Wherever possible, each provision of this Guaranty shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Guaranty shall be prohibited by or invalid under
such law, such provision shall be ineffective to the extent of such prohibition
or invalidity without invalidating the remainder of such provision or the
remaining provisions of this Guaranty.
XXIX.   Merger. This Guaranty represents the final agreement of each of the
Guarantors with respect to the matters contained herein and may not be
contradicted by evidence of prior or contemporaneous agreements, or subsequent
oral agreements, between the Guarantor and any holder of Obligations or the
Administrative Agent.

XXX.    Headings.  Section headings in this Guaranty are for convenience of
reference only and shall not govern the interpretation of any provision of this
Guaranty.

$_______________                                          Chicago, Illinois
                                                          [DATE]

     FOR VALUE RECEIVED, the undersigned, CHICAGO BRIDGE & IRON COMPANY N.V., a

defined in the Credit Agreement.

          The undersigned Borrower promises to pay interest on the unpaid

Agreement, among other things, (i) provides for the making of Revolving Loans by
the Lender to the undersigned Borrower and the other Borrowers under the Credit

          The undersigned, ______________ (the "Subsidiary"), a __________

as evidenced by their execution of the Notes. Any portion of the text of any
Note may be set forth on the reverse thereof, with an appropriate reference
thereto on the face of the Note.

                  (b) The Definitive Notes shall be typewritten, printed,
lithographed or engraved or produced by any combination of these methods (with
or without steel engraved borders), all as determined by the officers executing
such Notes, as evidenced by their execution of such Notes.

                  (c) Each Note shall be dated the date of its authentication.
The terms of the Notes set forth in Exhibits D and E are part of the terms of
this Indenture.

                  SECTION 2.2 Execution, Authentication and Delivery. The Notes
shall be executed on behalf of Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Notes may be manual or
facsimile.

                  (a) Notes bearing the manual or facsimile signature of
individuals who were at any time Authorized Officers of Issuer shall bind
Issuer, notwithstanding that such individuals or any of them have ceased to hold
such offices prior to the authentication and delivery of such Notes or did not
hold such offices at the date of such Notes.

                  (b) Indenture Trustee shall upon Issuer Order authenticate and
deliver Class A- 1 Notes for original issue in an aggregate principal amount of
$____________ and Class A-2 Notes for original issue in the aggregate principal

$1,000).

                  (d) No Note shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose, unless there appears on
such Note a certificate of authentication substantially in the form provided for

<PAGE>   8

signature of one of its authorized signatories, and such certificate upon any
Note shall be conclusive evidence, and the only evidence, that such Note has
been duly authenticated and delivered hereunder.

                  SECTION 2.3 Temporary Notes.

                  (a) Pending the preparation of Definitive Notes, Issuer may
execute, and upon receipt of an Issuer Order, Indenture Trustee shall
authenticate and deliver, temporary Notes which are printed, lithographed,
typewritten, mimeographed or otherwise produced, of the tenor of the Definitive
Notes in lieu of which they are issued and with such variations not inconsistent
with the terms of this Indenture as the officers executing such Notes may
determine, as evidenced by their execution of such Notes.

                  (b) If temporary Notes are issued, Issuer will cause
Definitive Notes to be prepared without unreasonable delay. After the
preparation of Definitive Notes, the temporary Notes shall be exchangeable for
Definitive Notes upon surrender of the temporary Notes at the office or agency

                  (a) Issuer shall cause to be kept a register (the "Note
Register") in which, subject to such reasonable regulations as it may prescribe,
Issuer shall provide for the registration of Notes and the registration of
transfers of Notes. Indenture Trustee shall initially be "Note Registrar" for
the purpose of registering Notes and transfers of Notes as herein provided. Upon
any resignation of any Note Registrar, Issuer shall promptly appoint a successor
or, if it elects not to make such an appointment, assume the duties of Note
Registrar.

                  (b) If a Person other than Indenture Trustee is appointed by
Issuer as Note Registrar, Issuer will give Indenture Trustee prompt written
notice of the appointment of such Note Registrar and of the location, and any
change in the location, of the Note Register, and Indenture Trustee shall have
the right to inspect the Note Register at all reasonable times and to obtain
copies thereof, and Indenture Trustee shall have the right to conclusively rely
upon a certificate executed on behalf of Note Registrar by an Executive Officer
thereof as to the names and addresses of the Holders of the Notes and the
principal amounts and number of such Notes.

                  (c) Upon surrender for registration of transfer of any Note at
the office or agency of Issuer to be maintained as provided in Section 3.2, if
the requirements of Section 8-401(1) of the UCC are met Issuer shall execute and
upon its written request Indenture Trustee shall authenticate and the Noteholder
shall obtain from Indenture Trustee, in the name of the designated transferee or
transferees, one or more new Notes, in any authorized denominations, of the same
class and a like aggregate principal amount.

                                       4
<PAGE>   9

                  (d) At the option of the Holder, Notes may be exchanged for
other Notes in any authorized denominations, of the same class and a like
aggregate principal amount, upon surrender of the Notes to be exchanged at such
office or agency. Whenever any Notes are so surrendered for exchange, if the
requirements of Section 8-401(1) of the UCC are met Issuer shall execute and
upon its written request Indenture Trustee shall authenticate and the Noteholder
shall obtain from Indenture Trustee, the Notes which the Noteholder making the
exchange is entitled to receive.

                  (e) All Notes issued upon any registration of transfer or
exchange of Notes shall be the valid obligations of Issuer, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Notes
surrendered upon such registration of transfer or exchange.

                  (f) Every Note presented or surrendered for registration of
transfer or exchange shall be (i) duly endorsed by, or be accompanied by a
written instrument of transfer in form satisfactory to Note Registrar duly
executed by, the Holder thereof or such Holder's attorney duly authorized in
writing, with such signature guaranteed by an "eligible guarantor institution"
meeting the requirements of Note Registrar which requirements include membership
or participation in a Securities Transfer Agents Medallion Program ("Stamp") or
such other "signature guarantee program" as may be determined by Note Registrar
in addition to, or in substitution for, Stamp, all in accordance with the
Exchange Act, and (ii) accompanied by such other documents as Indenture Trustee
may require.

                  (g) No service charge shall be made to a Holder for any
registration of transfer or exchange of Notes, but Issuer may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of Notes,
other than exchanges pursuant to Section 2.3 or 9.6 not involving any transfer.

                  (h) The preceding provisions of this section notwithstanding,
Issuer shall not be required to make and Note Registrar need not register
transfers or exchanges of Notes selected for redemption or of any Note for a
period of 15 days preceding the due date for any payment with respect to the
Note.

                  SECTION 2.5 Mutilated, Destroyed, Lost or Stolen Notes.

                  (a) If (i) any mutilated Note is surrendered to Indenture
Trustee, or Indenture Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, and (ii) there is delivered to Indenture
Trustee such security or indemnity as may be required by it to hold Issuer and
Indenture Trustee harmless, then, in the absence of notice to Issuer, Note
Registrar or Indenture Trustee that such Note has been acquired by a bona fide
purchaser, and provided that the requirements of Section 8-405 of the UCC are
met, Issuer shall execute and upon its written request Indenture Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Note, a replacement Note; provided that if any such
destroyed, lost or stolen Note, but not a mutilated Note, shall have become or
within seven days shall be due and payable, or shall have been called for
redemption, instead of issuing a replacement Note, Issuer may upon delivery of
the security or indemnity herein required pay

                                       5
<PAGE>   10

such destroyed, lost or stolen Note when so due or payable or upon the
Redemption Date without surrender thereof. If, after the delivery of such
replacement Note or payment of a 6 destroyed, lost or stolen Note pursuant to
the proviso to the preceding sentence, a bona fide purchaser of the original
Note in lieu of which such replacement Note was issued presents for payment such
original Note, Issuer and Indenture Trustee shall be entitled to recover such
replacement Note (or such payment) from the Person to whom it was delivered or
any Person taking such replacement Note from such Person to whom such
replacement Note was delivered or any assignee of such Person, except a bona
fide purchaser, and shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred by
Issuer or Indenture Trustee in connection therewith.

                  (b) Upon the issuance of any replacement Note under this
Section 2.5, Issuer may require the payment by the Holder of such Note of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other reasonable expenses (including the fees and
expenses of Indenture Trustee) connected therewith.

                  (c) Every replacement Note issued pursuant to this Section 2.5
in replacement of any mutilated, destroyed, lost or stolen Note shall constitute
an original additional contractual obligation of Issuer, whether or not the
mutilated, destroyed, lost or stolen Note shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

                  (d) The provisions of this Section 2.5 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Notes.

                  SECTION 2.6 Persons Deemed Owner. Prior to due presentment for
registration of transfer of any Note, Issuer, Indenture Trustee and any agent of
Issuer or Indenture Trustee may treat the Person in whose name any Note is
registered (as of the day of determination) as the owner of such Note for the
purpose of receiving payments of principal of and interest, if any, on such Note
and for all other purposes whatsoever, whether or not such Note be overdue, and
neither Issuer, Indenture Trustee nor any agent of Issuer or Indenture Trustee
shall be affected by notice to the contrary.

                  SECTION 2.7 Payment of Principal and Interest.

                  (a) The Notes shall accrue interest as provided in the forms
of the Class A-1 Note and the Class A-2 Note, set forth in Exhibits D and E,
respectively, and such interest shall be payable on each Payment Date as
specified therein. Any installment of interest or principal, if any, payable on
any Note which is punctually paid or duly provided for by Issuer on the
applicable Payment Date shall be paid to the Person in whose name such Note (or
one or more Predecessor Notes) is registered on the Record Date, by check mailed
first-class, postage prepaid, to such Person's address as it appears on the Note
Register on such Record Date, except that, unless Definitive Notes have been
issued pursuant to Section 2.12, with respect to Notes registered on the Record
Date in the name of the nominee of the Clearing Agency (initially, such nominee
to be Cede & Co.), payment will be made by wire transfer in immediately
available funds to the account designated by such nominee and except for the
final installment of principal

                                       6
<PAGE>   11

payable with respect to such Note on a Payment Date or on the Final Scheduled
Payment Date (and except for the Redemption Price for any Note called for
redemption pursuant to Section 10.1(a)) which shall be payable as provided
below. The funds represented by any such checks returned undelivered shall be
held in accordance with Section 3.3.

                  (b) The principal of each Note shall be payable on each
Payment Date as provided in the forms of the Class A-1 Note and the Class A-2
Note, set forth in Exhibits D and E, respectively. Notwithstanding the
foregoing, the entire unpaid principal amount of the Notes shall be due and
payable, if not previously paid, on the date on which an Event of Default shall
have occurred and be continuing, if Indenture Trustee or the Holders of the
Notes representing not less than a majority of the Outstanding Amount of the
Notes have declared the Notes to be immediately due and payable in the manner
provided in Section 5.2 and, in such event, all principal payments on each class
of Notes shall be made pro rata to the Noteholders of such class entitled
thereto. Indenture Trustee shall notify the Person in whose name a Note is
registered at the close of business on the Record Date preceding the Payment
Date on which Issuer expects that the final installment of principal of and
interest on such Note will be paid. Such notice shall be mailed or transmitted
by facsimile prior to such final Payment Date and shall specify that such final
installment will be payable only upon presentation and surrender of such Note
and shall specify the place where such Note may be presented and surrendered for
payment of such installment. Notices in connection with redemptions of Notes
shall be mailed to Noteholders as provided in Section 10.2.

                  SECTION 2.8 Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than Indenture Trustee, be delivered to Indenture Trustee and shall
be promptly cancelled by Indenture Trustee. Issuer may at any time deliver to
Indenture Trustee for cancellation any Notes previously authenticated and
delivered hereunder which Issuer may have acquired in any manner whatsoever, and
all Notes so delivered shall be promptly cancelled by Indenture Trustee. No
Notes shall be authenticated in lieu of or in exchange for any Notes cancelled
as provided in this Section, except as expressly permitted by this Indenture.
All cancelled Notes may be held or disposed of by Indenture Trustee in
accordance with its standard retention or disposal policy as in effect at the
time unless Issuer shall direct by an Issuer Order that they be destroyed or
returned to it; provided that such Issuer Order is timely and the Notes have not
been previously disposed of by Indenture Trustee.

                  SECTION 2.9 Release of Collateral. Subject to Section 11.1,
Indenture Trustee shall release property from the lien of this Indenture only
upon receipt of an Issuer Request accompanied by an Officer's Certificate, an
Opinion of Counsel and Independent Certificates in accordance with TIA Sections
314(c) and 314(d)(1) or an Opinion of Counsel in lieu of such Independent
Certificates to the effect that TIA does not require any such Independent
Certificates. If the Commission shall issue an exemptive order under TIA Section
304(d) modifying Owner Trustee's obligations under TIA Sections 314(c) and
314(d)(1), subject to Section 11.1 and the terms of the Basic Documents,
Indenture Trustee shall release property from the lien of this Indenture in
accordance with the conditions and procedures set forth in such exemptive order.

                  SECTION 2.10 Book-Entry Notes. The Notes, upon original
issuance, will be issued in the form of typewritten Notes representing the
Book-Entry Notes, to be delivered to _____________________, as agent for The
Depository Trust Company, the initial Clearing Agency, by, or on behalf of,
Issuer. Such Notes shall initially be registered on the Note Register in the
name of Cede & Co., the nominee of the initial Clearing Agency, and no Note
Owner will receive a Definitive Note representing such Note Owner's interest in
such Note, except as provided in Section 2.12. Unless and until definitive,
fully registered Notes (the "Definitive Notes") have been issued to Note Owners
pursuant to Section 2.12:

                  (a) the provisions of this Section shall be in full force and
effect;

                  (b) Note Registrar and Indenture Trustee shall be entitled to
deal with the Clearing Agency for all purposes of this Indenture (including the
payment of principal of and interest on the Notes and the giving of instructions
or directions hereunder) as the sole Holder of the Notes, and shall have no
obligation to the Note Owners;

                  (c) to the extent that the provisions of this Section conflict
with any other provisions of this Indenture, the provisions of this Section
shall control;

                  (d) the rights of Note Owners shall be exercised only through
the Clearing Agency and shall be limited to those established by law and
agreements between such Note Owners and the Clearing Agency and/or the Clearing
Agency Participants or Persons acting through Clearing Agency Participants.
Pursuant to the Note Depository Agreement, unless and until Definitive Notes are
issued pursuant to Section 2.12, the initial Clearing Agency will make
book-entry transfers among the Clearing Agency Participants and receive and
transmit payments of principal of and interest on the Notes to such Clearing
Agency Participants; and

                  (e) whenever this Indenture requires or permits actions to be
taken based upon instructions or directions of Holders of Notes evidencing a
specified percentage of the Outstanding Amount of the Notes, the Clearing Agency
shall be deemed to represent such percentage only to the extent that it has
received instructions to such effect from Note Owners and/or Clearing Agency
Participants or Persons acting through Clearing Agency Participants owning or
representing, respectively, such required percentage of the beneficial interest
in the Notes and has delivered such instructions to Indenture Trustee.

                  SECTION 2.11 Notices to Clearing Agency. Whenever a notice or
other communication to the Noteholders is required under this Indenture, unless
and until Definitive Notes shall have been issued to Note Owners pursuant to
Section 2.12, Indenture Trustee shall give all such notices and communications
specified herein to be given to Holders of the Notes to the Clearing Agency, and
shall have no obligation to the Note Owners.

                  SECTION 2.12 Definitive Notes. If (a) Seller advises Indenture
Trustee in writing that the Clearing Agency is no longer willing or able to
properly discharge its responsibilities with respect to the Notes, and Seller is
unable to locate a qualified successor, (b) Seller at its option advises
Indenture Trustee in writing that it elects to terminate the book-entry system
through the Clearing Agency or (c) after the occurrence of an Event of Default,
Note Owners representing beneficial interests aggregating at least a majority of
the Outstanding

                                       8
<PAGE>   13

Amount of the Notes advise Indenture Trustee through the Clearing Agency in
writing that the continuation of a book entry system through the Clearing Agency
is no longer in the best interests of the Note Owners, then the Clearing Agency
shall notify all Note Owners and Indenture Trustee of the occurrence of any such
event and of the availability of Definitive Notes to Note Owners requesting the
same. Upon surrender to Indenture Trustee of the typewritten Note or Notes
representing the Book-Entry Notes by the Clearing Agency, accompanied by
registration instructions, Issuer shall execute and Indenture Trustee shall
authenticate the Definitive Notes in accordance with the instructions of the
Clearing Agency. None of Issuer, Note Registrar or Indenture Trustee shall be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be protected in relying on, such instructions. Upon the issuance
of Definitive Notes, Indenture Trustee shall recognize the Holders of the
Definitive Notes as Noteholders.

                  SECTION 2.13 Authenticating Agents.

                  (a) The Indenture Trustee may appoint one or more Persons
(each, an "Authenticating Agent") with power to act on its behalf and subject to
its direction in the authentication of Notes in connection with issuance,
transfers and exchanges under Sections 2.2, 2.3, 2.4 and 2.5, as fully to all
intents and purposes as though each such Authenticating Agent had been expressly
authorized by those Sections to authenticate such Notes. For all purposes of
this Indenture, the authentication of Notes by an Authenticating Agent pursuant
to this Section shall be deemed to be the authentication of Notes "by the
Indenture Trustee."

                  (b) Any corporation into which any Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any
Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of any Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, without the
execution or filing of any further act on the part of the parties hereto or such
Authenticating Agent or such successor corporation.

                  (c) Any Authenticating Agent may at any time resign by giving
written notice of resignation to Indenture Trustee and Owner Trustee. Indenture
Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent and Owner
Trustee. Upon receiving such notice of resignation or upon such a termination,
Indenture Trustee may appoint a successor Authenticating Agent and shall give
written notice of any such appointment to Owner Trustee.

                  (d) The Administrator agrees to pay to each Authenticating
Agent from time to time reasonable compensation for its services. The provisions
of Sections 2.8 and 6.4 shall be applicable to any Authenticating Agent.

                  SECTION 2.14 Tax Treatment. Issuer has entered into this
Indenture, and the Notes shall be issued, with the intention that, for federal,
state and local income and franchise tax purposes, the Notes shall qualify as
indebtedness of Issuer secured by the Trust Estate. Issuer, by entering into
this Indenture, and each Noteholder, by its acceptance of a Note (and each Note
Owner by its acceptance of an interest in the applicable Book-Entry Note), agree
to

                                       9
<PAGE>   14

treat the Notes for federal, state and local income and franchise tax purposes
as indebtedness of Issuer.

                             ARTICLE III COVENANTS.

                  SECTION 3.1 Payment of Principal and Interest. Issuer will
duly and punctually pay the principal of and interest on the Notes in accordance
with the terms of the Notes and this Indenture. Without limiting the foregoing,
subject to Section 8.2(c), Issuer will cause to be distributed all amounts on
deposit in the Note Distribution Account on a Payment Date deposited therein
pursuant to the Sale and Servicing Agreement (i) in the Class A-1 Noteholders'
Interest Distributable Amount, to Class A-1 Noteholders and (ii) in the Class
A-2 Noteholders' Interest Distributable Amount, to Class A-2 Noteholders.
Amounts properly withheld under the Code by any Person from a payment to any
Noteholder of interest and/or principal shall be considered as having been paid
by Issuer to such Noteholder for all purposes of this Indenture.

                  SECTION 3.2 Maintenance of Office or Agency. Issuer will
maintain in the Borough of Manhattan, The City of New York, an office or agency
where Notes may be surrendered for registration of transfer or exchange, and
where notices and demands to or upon Issuer in respect of the Notes and this
Indenture may be served. Issuer hereby initially appoints Indenture Trustee to
serve as its agent for the foregoing purposes. Issuer will give prompt written
notice to Indenture Trustee of the location, and of any change in the location,
of any such office or agency. If at any time Issuer shall fail to maintain any
such office or agency or shall fail to furnish Indenture Trustee with the
address thereof, such surrenders, notices and demands may be made or served at
the Corporate Trust Office, and Issuer hereby appoints Indenture Trustee as its
agent to receive all such surrenders, notices and demands.

                  SECTION 3.3 Money for Payments To Be Held in Trust.

                  (a) As provided in Section 8.2, all payments of amounts due
and payable with respect to any Notes that are to be made from amounts withdrawn
from the Collection Account and the Note Distribution Account pursuant to
Section 8.2(c) shall be made on behalf of Issuer by Indenture Trustee or by
another Paying Agent, and no amounts so withdrawn from the Collection Account
and the Note Distribution Account for payments of Notes shall be paid over to
Issuer except as provided in this Section.

                  (b) On or before each Payment Date and Redemption Date, Issuer
shall deposit or cause to be deposited in the Note Distribution Account an
aggregate sum sufficient to pay the amounts then becoming due under the Notes,
such sum to be held in trust for the benefit of the Persons entitled thereto and
(unless the Paying Agent is Indenture Trustee) shall promptly notify Indenture
Trustee of its action or failure so to act.

                  (c) Issuer will cause each Paying Agent other than Indenture
Trustee to execute and deliver to Indenture Trustee an instrument in which such
Paying Agent shall agree with Indenture Trustee (and if Indenture Trustee acts
as Paying Agent, it hereby so agrees), subject to the provisions of this
Section, that such Paying Agent will:

                  (i) hold all sums held by it for the payment of amounts due
         with respect to the Notes in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid

                                       10
<PAGE>   15

         to such Persons or otherwise disposed of as herein provided and pay
         such sums to such Persons as herein provided;

                  (ii) give Indenture Trustee notice of any default by Issuer
         (or any other obligor upon the Notes) of which it has actual knowledge
         in the making of any payment required to be made with respect to the
         Notes;

                  (iii) at any time during the continuance of any such default,
         upon the written request of Indenture Trustee, forthwith pay to
         Indenture Trustee all sums so held in trust by such Paying Agent;

                  (iv) immediately resign as a Paying Agent and forthwith pay to
         Indenture Trustee all sums held by it in trust for the payment of Notes
         if at any time it ceases to meet the standards required to be met by a
         Paying Agent at the time of its appointment; and

                  (v) comply with all requirements of the Code with respect to
         the withholding from any payments made by it on any Notes of any
         applicable withholding taxes imposed thereon and with respect to any
         applicable reporting requirements in connection therewith.

                  (d) Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, by Issuer
Order direct any Paying Agent to pay to Indenture Trustee all sums held in trust
by such Paying Agent, such sums to be held by Indenture Trustee upon the same
trusts as those upon which the sums were held by such Paying Agent; and upon
such a payment by any Paying Agent to Indenture Trustee, such Paying Agent shall
be released from all further liability with respect to such money.

                  (e) Subject to applicable laws with respect to the escheat of
funds, any money held by Indenture Trustee or any Paying Agent in trust for the
payment of any amount due with respect to any Note and remaining unclaimed for
two years after such amount has become due and payable shall be discharged from
such trust and be paid to Issuer on Issuer Request; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to Issuer for
payment thereof (but only to the extent of the amounts so paid to Issuer), and
all liability of Indenture Trustee or such Paying Agent with respect to such
trust money shall thereupon cease; provided that Indenture Trustee or such
Paying Agent, before being required to make any such repayment, shall at the
expense of Issuer cause to be published once, in a newspaper published in the
English language, customarily published on each Business Day and of general
circulation in The City of New York, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to Issuer. Indenture Trustee shall also adopt and
employ, at the expense of Issuer, any other reasonable means of notification of
such repayment (including, but not limited to, mailing notice of such repayment
to Holders whose Notes have been called but have not been surrendered for
redemption or whose right to or interest in moneys due and payable but not
claimed is determinable from the records of Indenture Trustee or of any Paying
Agent, at the last address of record for each such Holder).

<PAGE>   16

                  SECTION 3.4 Existence. Except as otherwise permitted by the
provisions of Section 3.10, Issuer will keep in full effect its existence,
rights and franchises as a _______________ under the laws of the State of
___________ (unless it becomes, or any successor Issuer hereunder is or becomes,
organized under the laws of any other state or of the United States of America,
in which case Issuer will keep in full effect its existence, rights and
franchises under the laws of such other jurisdiction) and will obtain and
preserve its qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes, the Collateral and each other
instrument or agreement included in the Trust Estate.

                  SECTION 3.5 Protection of Trust Estate. Issuer will from time
to time prepare (or shall cause to be prepared), execute and deliver all such
supplements and amendments hereto and all such financing statements,
continuation statements, instruments of further assurance and other instruments,
and will take such other action necessary or advisable to:

                  (a) maintain or preserve the lien and security interest (and
the priority thereof) of this Indenture or carry out more effectively the
purposes hereof;

                  (b) perfect, publish notice of or protect the validity of any
Grant made or to be made by this Indenture;

                  (c) enforce any of the Collateral; or

                  (d) preserve and defend title to the Trust Estate and the
rights of Indenture Trustee and the Noteholders in such Trust Estate against the
claims of all persons and parties.

Issuer hereby designates Indenture Trustee its agent and attorney-in-fact to
execute any financing statement, continuation statement or other instrument
required by Issuer pursuant to this Section.

                  SECTION 3.6 Opinions as to Trust Estate.

                  (a) On the Closing Date, Issuer shall furnish to Indenture
Trustee an Opinion of Counsel either stating that, in the opinion of such
counsel, such action has been taken with respect to the recording and filing of
this Indenture, any indentures supplemental hereto, and any other requisite
documents, and with respect to the execution and filing of any financing
statements and continuation statements, as are necessary to perfect and make
effective the lien and security interest of this Indenture and reciting the
details of such action, or stating that, in the opinion of such counsel, no such
action is necessary to make such lien and security interest effective.

                  (b) Within 120 days after the beginning of each calendar year
which commences more than three months after the Cutoff Date, Issuer shall
furnish to Indenture Trustee an Opinion of Counsel either stating that, in the
opinion of such counsel, such action has been taken with respect to the
recording, filing, re-recording and refiling of this Indenture, any indentures
supplemental hereto and any other requisite documents and with respect to the
execution and filing of any financing statements and continuation statements as
are necessary to maintain the lien and security interest created by this
Indenture and reciting the details of such action or stating that in the opinion
of such counsel no such action is necessary to maintain such

                                       12
<PAGE>   17

lien and security interest. Such Opinion of Counsel shall also describe the
recording, filing, re-recording and refiling of this Indenture, any indentures
supplemental hereto and any other requisite documents and the execution and
filing of any financing statements and continuation statements that will, in the
opinion of such counsel, be required to maintain the lien and security interest
of this Indenture until January 30 in the following calendar year.

                  SECTION 3.7 Performance of Obligations; Servicing of
Receivables.

                  (a) Issuer will not take any action and will use its best
efforts not to permit any action to be taken by others that would release any
Person from any of such Person's material covenants or obligations under any
instrument or agreement included in the Trust Estate or that would result in the
amendment, hypothecation, subordination, termination or discharge of, or impair
the validity or effectiveness of, any such instrument or agreement, except as
ordered by any bankruptcy or other court or as expressly provided in this
Indenture, the Basic Documents or such other instrument or agreement.

                  (b) Issuer may contract with other Persons to assist it in
performing its duties under this Indenture, and any performance of such duties
by a Person identified to Indenture Trustee in an Officer's Certificate of
Issuer shall be deemed to be action taken by Issuer. Initially, Issuer has
contracted with Servicer and the Administrator to assist Issuer in performing
its duties under this Indenture.

                  (c) Issuer will punctually perform and observe all of its
obligations and agreements contained in this Indenture, the Basic Documents and
in the instruments and agreements included in the Trust Estate, including but
not limited to preparing (or causing to prepared) and filing (or causing to be
filed) all UCC financing statements and continuation statements required to be
filed by the terms of this Indenture and the Sale and Servicing Agreement in
accordance with and within the time periods provided for herein and therein.
Except as otherwise expressly provided therein, Issuer shall not waive, amend,
modify, supplement or terminate any Basic Document or any provision thereof
without the consent of Indenture Trustee or the Holders of at least a majority
of the Outstanding Amount of the Notes.

                  (d) If Issuer shall have knowledge of the occurrence of a
Servicer Termination Event under the Sale and Servicing Agreement, Issuer shall
promptly notify Indenture Trustee and the Rating Agencies thereof in accordance
with Section 11.4, and shall specify in such notice the action, if any, Issuer
is taking in respect of such default. If a Servicer Termination Event shall
arise from the failure of Servicer to perform any of its duties or obligations
under the Sale and Servicing Agreement with respect to the Receivables, Issuer
shall take all reasonable steps available to it to remedy such failure.

                  (e) As promptly as possible after the giving of notice of
termination to Servicer of Servicer's rights and powers pursuant to Section 8.1
of the Sale and Servicing Agreement, Issuer shall appoint a successor servicer
(the "Successor Servicer"), and such Successor Servicer shall accept its
appointment by a written assumption in a form acceptable to Indenture Trustee.
In the event that a Successor Servicer has not been appointed and accepted its
appointment at the time when Servicer ceases to act as Servicer, Indenture
Trustee without further action shall automatically be appointed the Successor
Servicer. Indenture Trustee may

                                       13
<PAGE>   18

resign as Servicer by giving written notice of such resignation to Issuer and in
such event will be released from such duties and obligations, such release not
to be effective until the date a new servicer enters into a servicing agreement
with Issuer as provided below. Upon delivery of any such notice to Issuer,
Issuer shall obtain a new servicer as the Successor Servicer under the Sale and
Servicing Agreement. Any Successor Servicer other than Indenture Trustee shall
(i) be an established financial institution having a net worth of not less than
$50,000,000 and whose regular business includes the servicing of motor vehicle
loans and (ii) enter into a servicing agreement with Issuer having substantially
the same provisions as the provisions of the Sale and Servicing Agreement
applicable to Servicer. If within 30 days after the delivery of the notice
referred to above, Issuer shall not have obtained such a new servicer, Indenture
Trustee may appoint, or may petition a court of competent jurisdiction to
appoint, a Successor Servicer. In connection with any such appointment,
Indenture Trustee may make such arrangements for the compensation of such
successor as it and such successor shall agree, subject to the limitations set
forth below and in the Sale and Servicing Agreement, and in accordance with
Section 8.2 of the Sale and Servicing Agreement, Issuer shall enter into an
agreement with such successor for the servicing of the Receivables (such
agreement to be in form and substance satisfactory to Indenture Trustee). If
Indenture Trustee shall succeed to Servicer's duties as servicer of the
Receivables as provided herein, it shall do so in its individual capacity and
not in its capacity as Indenture Trustee and, accordingly, the provisions of
Article VI shall be inapplicable to Indenture Trustee in its duties as the
successor to Servicer and the servicing of the Receivables. In case Indenture
Trustee shall become successor to Servicer under the Sale and Servicing
Agreement, Indenture Trustee shall be entitled to appoint as Servicer any one of
its Affiliates, or delegate any of its responsibilities as Servicer to agents,
subject to the terms of the Sale and Servicing Agreement, provided that such
appointment or delegation shall not affect or alter in any way the liability of
Indenture Trustee as a successor for the performance of the duties and
obligations of Servicer in accordance with the terms hereof.

                  (f) Upon any termination of Servicer's rights and powers
pursuant to the Sale and Servicing Agreement, Issuer shall promptly notify
Indenture Trustee. As soon as a Successor Servicer (other than Indenture
Trustee) is appointed, Issuer shall notify Indenture Trustee of such
appointment, specifying in such notice the name and address of such Successor
Servicer.

                  (g) Without derogating from the absolute nature of the
assignment granted to Indenture Trustee under this Indenture or the rights of
Indenture Trustee hereunder, Issuer agrees that, unless such action is
specifically permitted hereunder or under the Basic Documents, it will not,
without the prior written consent of Indenture Trustee or the Holders of at
least a majority in Outstanding Amount of the Notes, amend, modify, waive,
supplement, terminate or surrender, or agree to any amendment, modification,
supplement, termination, waiver or surrender of, the terms of any Collateral or
the Basic Documents, or waive timely performance or observance by Servicer or
Seller under the Sale and Servicing Agreement; provided that no such amendment
shall (i) except for amendments and modifications of the Receivables permitted
under the Sale and Servicing Agreement, increase or reduce in any manner the
amount of, or accelerate or delay the timing of, distributions that are required
to be made for the benefit of the Noteholders, or (ii) reduce the aforesaid
percentage of the Notes which are required to consent to any such amendment,
without the consent of the Holders of all the Outstanding Notes. If any such
amendment, modification, supplement or waiver shall be so consented to by
Indenture Trustee or

                                       14
<PAGE>   19

such Holders, Issuer agrees, promptly following a request by Indenture Trustee
to do so, to execute and deliver, in its own name and at its own expense, such
agreements, instruments, consents and other documents as Indenture Trustee may
deem necessary or appropriate in the circumstances.

                  SECTION 3.8 Negative Covenants. So long as any Notes are
Outstanding, Issuer shall not:

                  (a) except as expressly permitted by this Indenture or the
Basic Documents, sell, transfer, exchange or otherwise dispose of any of the
properties or assets of Issuer, including those included in the Trust Estate,
unless directed to do so by Indenture Trustee;

                  (b) claim any credit on, or make any deduction from the
principal or interest payable in respect of, the Notes (other than amounts
properly withheld from such payments under the Code) or assert any claim against
any present or former Noteholder by reason of the payment of the taxes levied or
assessed upon any part of the Trust Estate;

                  (c) dissolve or liquidate in whole or in part; or

                  (d) (i) permit the validity or effectiveness of this Indenture
to be impaired, or permit the lien of this Indenture to be amended,
hypothecated, subordinated, terminated or discharged, or permit any Person to be

declaration the unpaid principal amount of such Notes, together with accrued and
unpaid interest thereon through the date of acceleration, shall become
immediately due and payable.

                  (b) At any time after such declaration of acceleration of
maturity has been made and before a judgment or decree for payment of the money
due has been obtained by Indenture Trustee as hereinafter in this Article V
provided, the Holders of Notes representing a majority of the Outstanding Amount
of the Notes, by written notice to Issuer and Indenture Trustee, may rescind and
annul such declaration and its consequences if:

                  (i) Issuer has paid or deposited with Indenture Trustee a sum
         sufficient to pay

                           (A) all payments of principal of and interest on all
                  Notes and all other amounts that would then be due hereunder
                  or upon such Notes if the Event of Default giving rise to such
                  acceleration had not occurred; and

                           (B) all sums paid or advanced by Indenture Trustee
                  hereunder and the reasonable compensation, expenses,

                  of the principal of the Notes that has become due solely by
                  such acceleration, have been cured or waived as provided in
                  Section 5.12.

No such rescission shall affect any subsequent default or impair any right
consequent thereto.

<PAGE>   26

                  SECTION 5.3 Collection of Indebtedness and Suits for
Enforcement by Indenture Trustee. (a) Issuer covenants that if (i) default is
made in the payment of any interest on any Note when the same becomes due and
payable, and such default continues for a period of five days, or (ii) default
is made in the payment of the principal of or any installment of the principal
of any Note when the same becomes due and payable, Issuer will, upon demand of
Indenture Trustee, pay to it, for the benefit of the Holders of the Notes, the
whole amount then due and payable on such Notes for principal and interest, with
interest upon the overdue principal, and, to the extent payment at such rate of
interest shall be legally enforceable, upon overdue installments of interest, at
the rate specified in Section 2.7 and in addition thereto such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of Indenture
Trustee and its agents and counsel.

                  (b) In case Issuer shall fail forthwith to pay such amounts
upon such demand, Indenture Trustee, in its own name and as trustee of an
express trust, may institute a proceeding for the collection of the sums so due
and unpaid, and may prosecute such proceeding to judgment or final decree, and
may enforce the same against Issuer or other obligor upon such Notes and collect
in the manner provided by law out of the property of Issuer or other obligor
upon such Notes, wherever situated, the moneys adjudged or decreed to be
payable.

                  (c) If an Event of Default occurs and is continuing, Indenture
Trustee may, as more particularly provided in Section 5.4, in its discretion,
proceed to protect and enforce its rights and the rights of the Noteholders, by
such appropriate proceedings as Indenture Trustee shall deem most effective to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy or legal or equitable
right vested in Indenture Trustee by this Indenture or by law.

                  (d) In case there shall be pending, relative to Issuer or any
other obligor upon the Notes or any Person having or claiming an ownership
interest in the Trust Estate, proceedings under Title 11 of the United States
Code or any other applicable Federal or state bankruptcy, insolvency or other
similar law, or in case a receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of Issuer or its property or such other
obligor or Person, or in case of any other comparable judicial proceedings
relative to Issuer or other obligor upon the Notes, or to the creditors or
property of Issuer or such other obligor, irrespective of whether the principal
of any Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether Indenture Trustee shall
have made any demand pursuant to the provisions of this Section, Indenture
Trustee shall be entitled and empowered, by intervention in such proceedings or

         Indenture Trustee and each predecessor Indenture Trustee, except as a
         result of negligence, bad faith or willful misconduct) and of the
         Noteholders allowed in such proceedings;

                  (ii) unless prohibited by applicable law and regulations, to
         vote on behalf of the Holders of Notes in any election of a trustee, a
         standby trustee or person performing similar functions in any such
         proceedings;

                  (iii) to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute all amounts
         received with respect to the claims of the Noteholders and of Indenture
         Trustee on their behalf; and

                  (iv) to file such proofs of claim and other papers or
         documents as may be necessary or advisable in order to have the claims
         of Indenture Trustee or the Holders of Notes allowed in any judicial

and any trustee, receiver, liquidator, custodian or other similar official in
any such proceeding is hereby authorized by each of such Noteholders to make
payments to Indenture Trustee, and, in the event that Indenture Trustee shall
consent to the making of payments directly to such Noteholders, to pay to
Indenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to Indenture Trustee, each predecessor Indenture Trustee and their
respective agents, attorneys and counsel, and all other expenses and liabilities
incurred, and all advances made, by Indenture Trustee and each predecessor
Indenture Trustee except as a result of negligence or bad faith.

                  (e) Nothing herein contained shall be deemed to authorize
Indenture Trustee to authorize or consent to or vote for or accept or adopt on
behalf of any Noteholder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof or to
authorize Indenture Trustee to vote in respect of the claim of any Noteholder in
any such proceeding except, as aforesaid, to vote for the election of a trustee
in bankruptcy or similar person.

                  (f) All rights of action and of asserting claims under this
Indenture, or under any of the Notes, may be enforced by Indenture Trustee
without the possession of any of the Notes or the production thereof in any
trial or other proceedings relative thereto, and any such action or proceedings
instituted by Indenture Trustee shall be brought in its own name as trustee of
an express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of Indenture Trustee, each predecessor
Indenture Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Holders of the Notes.

                  (g) In any proceedings brought by Indenture Trustee (and also
any proceedings involving the interpretation of any provision of this Indenture

represent all the Holders of the Notes, and it shall not be necessary to make
any Noteholder a party to any such proceedings.

                  SECTION 5.4 Remedies; Priorities. (a) If an Event of Default
shall have occurred and be continuing, Indenture Trustee may do one or more of
the following (subject to Section 5.5):

                  (i) institute proceedings in its own name and as trustee of an
         express trust for the collection of all amounts then payable on the
         Notes or under this Indenture with respect thereto, whether by
         declaration or otherwise, enforce any judgment obtained, and collect
         from Issuer and any other obligor upon such Notes moneys adjudged due;

                  (ii) institute proceedings from time to time for the complete
         or partial foreclosure of this Indenture with respect to the Trust
         Estate;

                  (iii) exercise any remedies of a secured party under the UCC
         and take any other appropriate action to protect and enforce the rights
         and remedies of Indenture Trustee and the Holders of the Notes; and

                  (iv) sell the Trust Estate or any portion thereof or rights or
         interest therein, at one or more public or private sales called and
         conducted in any manner permitted by law;

provided that Indenture Trustee may not sell or otherwise liquidate the Trust
Estate following an Event of Default, other than an Event of Default described
in Section 5.1(a) or (b), unless (A) the Holders of 100% of the Outstanding
Amount of the Notes and Certificates consent thereto, (B) the proceeds of such
sale or liquidation distributable to the Noteholders and Certificateholders are
sufficient to discharge in full all amounts then due and unpaid upon such Notes
and Certificates for principal and interest or (C) Indenture Trustee determines
that the Trust Estate will not continue to provide sufficient funds for the
payment of principal of and interest on the Notes as they would have become due
if the Notes had not been declared due and payable, and Indenture Trustee
obtains the consent of Holders of 66-2/3% of the Outstanding Amount of the
Notes. In determining such sufficiency or insufficiency with respect to clause
(B) and (C), Indenture Trustee may, but need not, obtain and rely upon an
opinion of an Independent investment banking or accounting firm of national
reputation as to the feasibility of such proposed action and as to the
sufficiency of the Trust Estate for such purpose.

                  (b) If Indenture Trustee collects any money or property
pursuant to this Article V, it shall pay out such money or property (and other
amounts including amounts held on deposit in the Reserve Account) held as
Collateral for the benefit of the Noteholders in the following order:

                  FIRST: to Indenture Trustee for amounts due under Section 6.7;

                  SECOND: to Servicer for due and unpaid Servicing Fees;

                  THIRD: to Noteholders for amounts due and unpaid on the Notes
for principal and interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Notes for interest;

                  FOURTH: to Noteholders for amounts due and unpaid on the Notes
for principal, ratably, without preference or priority of any kind, according to
the amounts due and payable on the Notes for principal; and

                                       24
<PAGE>   29

                  FIFTH: to Issuer for distribution to the
Certificateholders.

Indenture Trustee may fix a record date and payment date for any payment to
Noteholders pursuant to this Section. At least 15 days before such record date,
Issuer shall mail to each Noteholder and Indenture Trustee a notice that states
the record date, the payment date and the amount to be paid.

                  SECTION 5.5 Optional Preservation of the Receivables. If the
Notes have been declared to be due and payable under Section 5.2 following an
Event of Default and such declaration and its consequences have not been
rescinded and annulled, Indenture Trustee may, but need not, elect to maintain
possession of the Trust Estate. It is the desire of the parties hereto and the
Noteholders that there be at all times sufficient funds for the payment of
principal of and interest on the Notes, and Indenture Trustee shall take such
desire into account when determining whether or not to maintain possession of
the Trust Estate. In determining whether to maintain possession of the Trust
Estate, Indenture Trustee may, but need not, obtain and rely upon an opinion of
an Independent investment banking or accounting firm of national reputation as
to the feasibility of such proposed action and as to the sufficiency of the
Trust Estate for such purpose.

                  SECTION 5.6 Limitation of Suits. No Holder of any Note shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

                  (a) such Holder has previously given written notice to
Indenture Trustee of a continuing Event of Default;

                  (b) the Holders of not less than 25% of the Outstanding Amount
of the Notes have made written request to Indenture Trustee to institute such
proceeding in respect of such Event of Default in its own name as Indenture
Trustee hereunder;

                  (c) such Holder or Holders have offered to Indenture Trustee
indemnity reasonably satisfactory to it against the costs, expenses and
liabilities to be incurred in complying with such request;

                  (d) Indenture Trustee for 60 days after its receipt of such
notice, request and offer of indemnity has failed to institute such proceedings;
and

                  (e) no direction inconsistent with such written request has
been given to Indenture Trustee during such 60-day period by the Holders of a
majority of the Outstanding Amount of the Notes;

it being understood and intended that no one or more Holders of Notes shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Notes or to obtain or to seek to obtain priority or preference over
any other Holders or to enforce any right under this Indenture, except in the
manner herein provided.

<PAGE>   30

                  In the event Indenture Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Holders of Notes,
each representing less than a majority of the Outstanding Amount of the Notes,
Indenture Trustee in its sole discretion may determine what action, if any,
shall be taken, notwithstanding any other provisions of this Indenture.

                  SECTION 5.7 Unconditional Rights of Noteholders To Receive
Principal and Interest. Notwithstanding any other provisions in this Indenture,
the Holder of any Note shall have the right, which is absolute and
unconditional, to receive payment of the principal of and interest, if any, on
such Note on or after the respective due dates thereof expressed in such Note or
this Indenture (or, in the case of redemption, on or after the Redemption Date)
and to institute suit for the enforcement of any such payment, and such right
shall not be impaired without the consent of such Holder.

                  SECTION 5.8 Restoration of Rights and Remedies. If Indenture
Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy under this Indenture and such Proceeding has been discontinued or
abandoned for any reason or has been determined adversely to Indenture Trustee
or to such Noteholder, then and in every such case Issuer, Indenture Trustee and
the Noteholders shall, subject to any determination in such Proceeding, be
restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of Indenture Trustee and the Noteholders
shall continue as though no such Proceeding had been instituted.

                  SECTION 5.9 Rights and Remedies Cumulative. No right or remedy
herein conferred upon or reserved to Indenture Trustee or to the Noteholders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

                  SECTION 5.10 Delay or Omission Not a Waiver. No delay or
omission of Indenture Trustee or any Holder of any Note to exercise any right or
remedy accruing upon any Default or Event of Default shall impair any such right
or remedy or constitute a waiver of any such Default or Event of Default or an
acquiescence therein. Every right and remedy given by this Article V or by law
to Indenture Trustee or to the Noteholders may be exercised from time to time,
and as often as may be deemed expedient, by Indenture Trustee or by the
Noteholders, as the case may be.

                  SECTION 5.11 Control by Noteholders. The Holders of a majority
of the Outstanding Amount of the Notes shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to
Indenture Trustee with respect to the Notes or exercising any trust or power
conferred on Indenture Trustee; provided that

                  (a) such direction shall not be in conflict with any rule of
law or with this Indenture;

                                       26
<PAGE>   31

                  (b) subject to the express terms of Section 5.4, any direction
to Indenture Trustee to sell or liquidate the Trust Estate shall be by the
Holders of Notes representing not less than 100% of the Outstanding Amount of
the Notes;

                  (c) if the conditions set forth in Section 5.5 have been
satisfied and Indenture Trustee elects to retain the Trust Estate pursuant to
such Section, then any direction to Indenture Trustee by Holders of Notes
representing less than 100% of the Outstanding Amount of the Notes to sell or
liquidate the Trust Estate shall be of no force and effect;

                  (d) Indenture Trustee may take any other action deemed proper
by Indenture Trustee that is not inconsistent with such direction; and

                  (e) such direction shall be in writing; provided, further,
that, subject to Section 6.1, Indenture Trustee need not take any action that it
determines might involve it in liability or might materially adversely affect
the rights of any Noteholders not consenting to such action.

                  SECTION 5.12 Waiver of Past Defaults. Prior to the declaration
of the acceleration of the maturity of the Notes as provided in Section 5.2, the
Holders of Notes of not less than a majority of the Outstanding Amount of the
Notes may waive any past Default or Event of Default and its consequences except
a Default (a) in payment of principal of or interest on any of the Notes or (b)
in respect of a covenant or provision hereof which cannot be modified or amended
without the consent of the Holder of each Note. In the case of any such waiver,
Issuer, Indenture Trustee and the Holders of the Notes shall be restored to
their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other Default or impair any right consequent
thereto.

                  Upon any such waiver, such Default shall cease to exist and be
deemed to have been cured and not to have occurred, and any Event of Default
arising therefrom shall be deemed to have been cured and not to have occurred,
for every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereto.

                  SECTION 5.13 Undertaking for Costs. All parties to this
Indenture agree, and each Holder of any Note by such Holder's acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in
any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against Indenture Trustee for any action taken, suffered or omitted by
it as Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to (a) any suit instituted by
Indenture Trustee, (b) any suit instituted by any Noteholder, or group of
Noteholders, in each case holding in the aggregate more than 10% of the
Outstanding Amount of the Notes or (c) any suit instituted by any Noteholder for
the enforcement of the payment of principal of or interest on any Note on or
after the respective due dates expressed in such Note and in this Indenture (or,
in the case of redemption, on or after the Redemption Date).

                  SECTION 5.14 Waiver of Stay or Extension Laws. Issuer
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead or in any manner whatsoever, claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, that may affect the covenants or the performance of
this Indenture; and Issuer (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
Indenture Trustee, but will suffer and permit the execution of every such power
as though no such law had been enacted.

                  SECTION 5.15 Action on Notes. Indenture Trustee's right to
seek and recover judgment on the Notes or under this Indenture shall not be
affected by the seeking, obtaining or application of any other relief under or
with respect to this Indenture. Neither the lien of this Indenture nor any
rights or remedies of Indenture Trustee or the Noteholders shall be impaired by
the recovery of any judgment by Indenture Trustee against Issuer or by the levy
of any execution under such judgment upon any portion of the Trust Estate or
upon any of the assets of Issuer.

                  SECTION 5.16 Performance and Enforcement of Certain
Obligations. (a) Promptly following a request from Indenture Trustee to do so
and at Administrator's expense, Issuer agrees to take all such lawful action as
Indenture Trustee may request to compel or secure the performance and observance
by Seller and Servicer, as applicable, of each of their obligations to Issuer
under or in connection with the Sale and Servicing Agreement or by the Seller or
any Seller Affiliate, as applicable, of each of their obligations under or in
connection with each Purchase Agreement, in each case, in accordance with the
terms thereof, and to exercise any and all rights, remedies, powers and
privileges lawfully available to Issuer under or in connection with the Sale and
Servicing Agreement and each Purchase Agreement, as the case may be, to the
extent and in the manner directed by Indenture Trustee, including the
transmission of notices of default on the part of Seller, Servicer or applicable
Seller Affiliate thereunder and the institution of legal or administrative
actions or proceedings to compel or secure performance by Seller or Servicer of
each of their obligations under the Sale and Servicing Agreement or by the
Seller or any Seller Affiliate, as applicable, of each of their obligations
under or in connection with each Purchase Agreement.

                  (b) If an Event of Default has occurred and is continuing,
Indenture Trustee may, and, at the direction (which direction shall be in
writing or by telephone (confirmed in writing promptly thereafter)) of the
Holders of 66-2/3% of the Outstanding Amount of the Notes shall, exercise all
rights, remedies, powers, privileges and claims of Issuer against Seller or
Servicer under or in connection with the Sale and Servicing Agreement, or
against the Seller or Seller Affiliate under the applicable Purchase Agreement,
including the right or power to take any action to compel or secure performance
or observance by Seller, Servicer or applicable Seller Affiliate of each of
their obligations to Issuer thereunder and to give any consent, request, notice,
direction, approval, extension or waiver under the Sale and Servicing Agreement
or any Purchase Agreement, as applicable, and any right of Issuer to take such
action shall be suspended.

                  SECTION 6.1 Duties of Indenture Trustee. (a) If an Event of
Default has occurred and is continuing, of which a Responsible Officer of
Indenture Trustee has actual knowledge, Indenture Trustee shall exercise the
rights and powers vested in it by this Indenture and use the same degree of care
and skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.

                  (b) Except during the continuance of an Event of Default:

                  (i) Indenture Trustee undertakes to perform such duties and
         only such duties as are specifically set forth in this Indenture and no
         implied covenants or obligations shall be read into this Indenture
         against Indenture Trustee; and

                  (ii) in the absence of bad faith on its part, Indenture
         Trustee may conclusively rely, as to the truth of the statements and
         the correctness of the opinions expressed therein, upon certificates or
         opinions furnished to Indenture Trustee and conforming to the
         requirements of this Indenture; however, Indenture Trustee shall
         examine the certificates and opinions to determine whether or not they
         conform to the requirements of this Indenture.

                  (c) Indenture Trustee may not be relieved from liability for
its own negligent action, its own negligent failure to act or its own wilful
misconduct, except that:

                  (i) this paragraph does not limit the effect of paragraph (b)
         of this Section;

                  (ii) Indenture Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer unless it is
         proved that Indenture Trustee was negligent in ascertaining the
         pertinent facts; and

                  (iii) Indenture Trustee shall not be liable with respect to
         any action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 5.11.

                  (d) Indenture Trustee shall not be liable for interest on any
money received by it except as Indenture Trustee may agree in writing with
Issuer.

                  (e) Money held in trust by Indenture Trustee need not be
segregated from other funds except to the extent required by law or the terms of
this Indenture or the Sale and Servicing Agreement.

                  (f) No provision of this Indenture shall require Indenture
Trustee to expend or risk its own funds or otherwise incur financial liability
in the performance of any of its duties hereunder or in the exercise of any of
its rights or powers, if it shall have reasonable grounds to believe that
repayment of such funds or indemnity satisfactory to it against such risk or
liability is not assured to it.

<PAGE>   34

                  (g) Every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to Indenture Trustee shall
be subject to the provisions of this Section and to the provisions of the TIA.

investigate any fact or matter stated in the document.

                  (b) Before Indenture Trustee acts or refrains from acting, it
may require an Officer's Certificate or an Opinion of Counsel. Indenture Trustee

faith in reliance on the Officer's Certificate or Opinion of Counsel.

                  (c) Indenture Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys or a custodian or nominee, and Indenture Trustee shall not
be responsible for any misconduct or negligence on the part of, or for the
supervision of, Wells Fargo Auto Receivables Corporation, Wells Fargo Bank,
N.A., or any other such agent, attorney, custodian or nominee appointed with due
care by it hereunder. Indenture Trustee shall have no duty to monitor the
performance of Issuer.

                  (d) Indenture Trustee shall not be liable for any action it
takes or omits to take in good faith which it believes to be authorized or
within its rights or powers; provided, that Indenture Trustee's conduct does not
constitute wilful misconduct, negligence or bad faith.

                  (e) Indenture Trustee may consult with counsel, and the advice
or opinion of counsel with respect to legal matters relating to this Indenture
and the Notes shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

                  SECTION 6.3 Individual Rights of Indenture Trustee. Indenture
Trustee in its individual or any other capacity may become the owner or pledgee
of Notes and may otherwise deal with Issuer or its Affiliates with the same
rights it would have if it were not Indenture Trustee. Any Paying Agent, Note
Registrar, co-registrar or co-paying agent may do the same with like rights.
However, Indenture Trustee must comply with Sections 6.11 and 6.12.

                  SECTION 6.4 Indenture Trustee's Disclaimer. Indenture Trustee
shall not be responsible for and makes no representation as to the validity or
adequacy of this Indenture or the Notes, shall not be accountable for Issuer's
use of the proceeds from the Notes, and shall not be responsible for any
statement of Issuer in the Indenture or in any document issued in connection
with the sale of the Notes or in the Notes other than Indenture Trustee's
certificate of authentication.

                  SECTION 6.5 Notice of Defaults. If a Default occurs and is
continuing and if it is either actually known or written notice of the existence
thereof has been delivered to a Responsible Officer of Indenture Trustee,
Indenture Trustee shall mail to each Noteholder notice of the Default within 90
days after such knowledge or notice occurs. Except in the case of a Default in
payment of principal of or interest on any Note (including payments pursuant to
the mandatory redemption provisions of such Note), Indenture Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in
good faith determines that withholding the notice is in the interests of
Noteholders.

                  SECTION 6.6 Reports by Indenture Trustee to Holders. Indenture
Trustee shall deliver to each Noteholder such information as may be reasonably
required to enable such Holder to prepare its Federal and state income tax
returns.

                  SECTION 6.7 Compensation and Indemnity. (a) The compensation
and reimbursement of expenses of Indenture Trustee shall be governed by the
Administration Agreement. In addition, Issuer shall reimburse any expenses
incurred by the Indenture Trustee in pursuing remedies pursuant to Section 5.4.
Issuer has caused Administrator to agree to indemnify Indenture Trustee and its
officers, directors, employees and agents against any and all loss, liability or
expense (including attorneys' fees and expenses) incurred by it in connection
with the acceptance or the administration of this trust and the performance of
its duties hereunder. Neither Issuer nor Administrator need reimburse any
expense or indemnify against any loss, liability or expense incurred by
Indenture Trustee through Indenture Trustee's own wilful misconduct, negligence
or bad faith or to the extent arising from the breach by the Indenture Trustee
of any of its representations and warranties and covenants set forth herein.

                  (b) Issuer's payment obligations to Indenture Trustee pursuant
to this Section and the Administration Agreement referenced in the preceding
paragraph shall survive the discharge of this Indenture subject to a
satisfaction of the Rating Agency Condition. When Indenture Trustee incurs
expenses after the occurrence of a Default specified in Section 5.1(d) or (e)
with respect to Issuer, the expenses are intended to constitute expenses of
administration under Title 11 of the United States Code or any other applicable
Federal or state bankruptcy, insolvency or similar law.

                  SECTION 6.8 Replacement of Indenture Trustee. (a) Indenture
Trustee may resign at any time by so notifying Issuer. The Holders of a majority
in Outstanding Amount of the Notes may remove Indenture Trustee by so notifying
Indenture Trustee and may appoint a successor Indenture Trustee. Issuer shall
remove Indenture Trustee if:

                  (i) Indenture Trustee fails to comply with Section 6.11;

                  (ii) Indenture Trustee is adjudged a bankrupt or insolvent;

                  (iii) a receiver or other public officer takes charge of
         Indenture Trustee or its property; or

                  (iv) Indenture Trustee otherwise becomes incapable of acting.

                                       31
<PAGE>   36

                  (b) If Indenture Trustee resigns or is removed or if a vacancy
exists in the office of Indenture Trustee for any reason (Indenture Trustee in
such event being referred to herein as the retiring Indenture Trustee), Issuer
shall promptly appoint a successor Indenture Trustee.

                  (c) A successor Indenture Trustee shall deliver a written
acceptance of its appointment to the retiring Indenture Trustee and to Issuer.
Thereupon the resignation or removal of the retiring Indenture Trustee shall
become effective, and the successor Indenture Trustee shall have all the rights,
powers and duties of Indenture Trustee under this Indenture subject to
satisfaction of the Rating Agency Condition. The successor Indenture Trustee
shall mail a notice of its succession to Noteholders. The retiring Indenture
Trustee shall promptly transfer all property held by it as Indenture Trustee to
the successor Indenture Trustee.

                  (d) If a successor Indenture Trustee does not take office
within 60 days after the retiring Indenture Trustee resigns or is removed, the
retiring Indenture Trustee, Issuer or the Holders of a majority in Outstanding
Amount of the Notes may petition any court of competent jurisdiction for the
appointment of a successor Indenture Trustee.

                  (e) If Indenture Trustee fails to comply with Section 6.11,
any Noteholder may petition any court of competent jurisdiction for the removal
of Indenture Trustee and the appointment of a successor Indenture Trustee.

                  (f) Any resignation or removal of Indenture Trustee and
appointment of a Successor Indenture Trustee pursuant to any of the provisions
of this Section shall not become effective until acceptance of appointment by
the successor Indenture Trustee pursuant to this Section 6.8 and payment of all
fees and expenses owed to the outgoing Indenture Trustee.

                  (g) Notwithstanding the resignation or removal of Indenture
Trustee pursuant to this Section, Issuer's and Administrator's obligations under
Section 6.7 shall continue for the benefit of the retiring Indenture Trustee.

                  (h) Indenture Trustee shall not be liable for the acts or
omissions of any successor Indenture Trustee.

                  SECTION 6.9 Successor Indenture Trustee by Merger. (a) If
Indenture Trustee consolidates with, merges or converts into, or transfers all
or substantially all its corporate trust business or assets to, another
corporation or banking association, the resulting, surviving or transferee
corporation without any further act shall be the successor Indenture Trustee.
Indenture Trustee shall provide the Rating Agencies and the Administrator prior
written notice of any such transaction.

                  (b) In case at the time such successor or successors by
merger, conversion or consolidation to Indenture Trustee shall succeed to the
trusts created by this Indenture any of the Notes shall have been authenticated
but not delivered, any such successor to Indenture Trustee may adopt the
certificate of authentication of any predecessor trustee, and deliver such Notes
so authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to Indenture Trustee may authenticate such Notes
either in the name of any 39 predecessor hereunder or in the name of the
successor to Indenture Trustee; and in all such cases

                                       32
<PAGE>   37

such certificates shall have the full force which it is anywhere in the Notes or
in this Indenture provided that the certificate of Indenture Trustee shall have.

                  SECTION 6.10 Appointment of Co-Indenture Trustee or Separate
Indenture Trustee. (a) Notwithstanding any other provisions of this Indenture,
at any time, after delivering written notice to the Administrator, for the
purpose of meeting any legal requirement of any jurisdiction in which any part
of Issuer may at the time be located, Indenture Trustee shall have the power and
may execute and deliver all instruments to appoint one or more Persons to act as
a co-trustee or co-trustees, or separate trustee or separate trustees, of all or
any part of the Trust, and to vest in such Person or Persons, in such capacity
and for the benefit of the Noteholders, such title to the Trust, or any part
hereof, and, subject to the other provisions of this Section, such powers,
duties, obligations, rights and trusts as Indenture Trustee may consider
necessary or desirable. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
6.11 and no notice to Noteholders of the appointment of any co-trustee or
separate trustee shall be required under Section 6.8.

                  (b) Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                  (i) all rights, powers, duties and obligations conferred or
         imposed upon Indenture Trustee shall be conferred or imposed upon and
         exercised or performed by Indenture Trustee and such separate trustee
         or co-trustee jointly (it being understood that such separate trustee
         or co-trustee is not authorized to act separately without Indenture
         Trustee joining in such act), except to the extent that under any law
         of any jurisdiction in which any particular act or acts are to be
         performed Indenture Trustee shall be incompetent or unqualified to
         perform such act or acts, in which event such rights, powers, duties
         and obligations (including the holding of title to Issuer or any
         portion thereof in any such jurisdiction) shall be exercised and
         performed singly by such separate trustee or co-trustee, but solely at
         the direction of Indenture Trustee;

                  (ii) no trustee hereunder shall be personally liable by reason
         of any act or omission of any other trustee hereunder, including acts
         or omissions of predecess or successor trustees; and

                  (iii) Indenture Trustee may at any time accept the resignation
         of or remove any separate trustee or co-trustee.

                  (c) Any notice, request or other writing given to Indenture
Trustee shall be deemed to have been given to each of the then separate trustees
and co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article VI. Each separate trustee and co-trustee, upon
its acceptance of the trusts conferred, shall be vested with the estates or
property specified in its instrument of appointment, either jointly with
Indenture Trustee or separately, as may be provided therein, subject to all the
provisions of this Indenture, specifically including every provision of this
Indenture relating to the conduct of, affecting the liability of, or affording
protection to, Indenture Trustee. Every such instrument shall be filed with
Indenture Trustee.

                  (d) Any separate trustee or co-trustee may at any time
constitute Indenture Trustee its agent or attorney-in-fact with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of this Agreement on its behalf and in its name. If any separate trustee
or co-trustee shall die, become incapable of acting, resign or be removed, all
of its estates, properties, rights, remedies and trusts shall invest in and be
exercised by Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

                  SECTION 6.11 Eligibility; Disqualification. Indenture Trustee

         Noteholders, and (B) in the Class A-2 Noteholders' Interest

         there are not sufficient funds in the Note Distribution Account to pay
         the entire amount of accrued and unpaid interest then due on the Notes
         for the related Payment Date, the amount in the Note Distribution
         Account shall be applied to the payment of such interest on each class
         of the Notes pro rata on the basis of the total amount of such interest
         due on such class of Notes for such Payment Date;

                  (ii) payment of principal to the Holders of the Class A-1

         zero provided that if there are not sufficient funds in the Note
         Distribution Account to pay in full the principal amount of the

         Account shall be applied to the payment of principal on the Class A-1
         Notes on a pro rata basis; and

                  (iii) payment of principal to the Holders of the Class A-2

<PAGE>   41

upon Issuer Order, subject to the provisions of Section 5.1(b) of the Sale and

Agreement, on each Payment Date, all interest and other investment income (net
of losses and investment expenses) on funds on deposit in the Trust Accounts
shall be distributed to the Seller by the Indenture Trustee. Issuer will not
direct Indenture Trustee to make any investment of any funds or to sell any
investment held in any of the Trust Accounts unless the security interest
Granted and perfected in such account will continue to be perfected in such
investment or the proceeds of such sale, in either case without any further
action by any Person, and, in connection with any direction to Indenture Trustee
to make any such investment or sale, if requested by Indenture Trustee, Issuer
shall deliver to Indenture Trustee an Opinion of Counsel, acceptable to
Indenture Trustee, to such effect.

                  (b) Subject to Section 6.1(c), Indenture Trustee shall not in
any way be held liable by reason of any insufficiency in any of the Trust
Accounts resulting from any loss on any Eligible Investment included therein
except for losses attributable to Indenture Trustee's failure to make payments
on such Eligible Investments issued by Indenture Trustee, in its commercial
capacity as principal obligor and not as trustee, in accordance with their
terms.

                  (c) If (i) Issuer shall have failed to give investment
directions for any funds on deposit in the Trust Accounts to Indenture Trustee
by 11:00 a.m. Eastern Time (or such other time as may be agreed by Issuer and
Indenture Trustee) on any Business Day; (ii) a Default or Event of Default shall
have occurred and be continuing with respect to the Notes but the Notes shall
not have been declared due and payable pursuant to Section 5.2, or (iii) if such
Notes shall have been declared due and payable following an Event of Default,
amounts collected or receivable from the Trust Estate are being applied in
accordance with Section 5.5 as if there had not been such a declaration; then
Indenture Trustee shall, to the fullest extent practicable, invest and reinvest
funds in the Trust Accounts in one or more Eligible Investments. Indenture
Trustee shall not be liable for losses in respect of such investments in
Eligible Investments that comply with the requirements of the Basic Documents.

                  SECTION 8.4 Release of Trust Estate. (a) Subject to the
payment of its fees and expenses pursuant to Section 6.7, Indenture Trustee may,
and when required by the provisions of this Indenture shall, execute instruments
to release property from the lien of this Indenture, or convey Indenture
Trustee's interest in the same, in a manner and under circumstances that are not
inconsistent with the provisions of this Indenture. No party relying upon an
instrument executed by Indenture Trustee as provided in this Article VIII shall
be bound to ascertain Indenture Trustee's authority, inquire into the
satisfaction of any conditions precedent or see to the application of any
moneys.

                  (b) Indenture Trustee shall, at such time as there are no
Notes outstanding and all sums due Indenture Trustee pursuant to Section 6.7
have been paid, release any remaining portion of the Trust Estate that secured
the Notes from the lien of this Indenture and release to Issuer or any other
Person entitled thereto any funds then on deposit in the Trust Accounts.
Indenture Trustee shall release property from the lien of this Indenture
pursuant to this Section 8.4(b) only upon receipt of an Issuer Request
accompanied by an Officer's Certificate, an Opinion of Counsel and (if required
by the TIA) Independent Certificates in accordance with TIA Sections 314(c) and
314(d)(1) meeting the applicable requirements of Section 11.1.

pursuant to Section 8.4(a), accompanied by copies of any instruments involved,
and Indenture Trustee may also require as a condition to such action, an Opinion
of Counsel, in form and substance satisfactory to Indenture Trustee, stating the
legal effect of any such action, outlining the steps required to complete the
same, and concluding that all conditions precedent to the taking of such action
have been complied with and such action will not materially and adversely impair
the security for the Notes or the rights of the Noteholders in contravention of
the provisions of this Indenture; provided that such Opinion of Counsel shall
not be required to express an opinion as to the fair value of the Trust Estate.
Counsel rendering any such opinion may rely, without independent investigation,

Indenture Trustee in connection with any such action.

         indenture; provided that such action shall not materially and adversely
         affect the interests of the Holders of the Notes;

                  (vi) to evidence and provide for the acceptance of the
         appointment hereunder by a successor trustee with respect to the Notes
         and to add to or change any of the provisions of this Indenture as
         shall be necessary to facilitate the administration of the trusts
         hereunder by more than one trustee, pursuant to the requirements of
         Article VI;

                  (vii) to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to effect the
         qualification of this Indenture under the TIA or under any similar
         federal statute hereafter enacted and to add to this Indenture such
         other provisions as may be expressly required by the TIA; or (viii) (A)
         to add, modify or eliminate such provisions of the Indenture as may be
         necessary or advisable in order to enable all or a portion of Issuer to
         qualify as, and to permit an election to be made to cause all or a
         portion of Issuer to be treated as, a "financial asset securitization
         investment trust" as described in the provisions of the "Small Business
         Job Protection Act of 1996," or to enable all or a portion of the
         Issuer to qualify and an election to be made for similar treatment
         under such comparable subsequent federal income tax provisions as may
         ultimately be enacted into law, and (B) in connection with any such
         election, to modify or eliminate existing provisions set forth in this
         Indenture relating to the intended federal income tax treatment of the
         Notes or Certificates and Issuer in the absence of the election; it
         being a condition to any such amendment that each Rating Agency will
         have notified the Indenture Trustee in writing that the amendment will
         not result in a reduction or withdrawal of the rating of any
         outstanding Notes or Certificates with respect to which it is a Rating
         Agency; and

                  (viii) to add, modify or eliminate such provisions as may be
         necessary or advisable in order to enable (a) the transfer to Issuer of
         all or any portion of the Receivables to be derecognized under GAAP by
         Seller to Issuer, (b) Issuer to avoid becoming a member of Seller's
         consolidated group under GAAP or (c) the Seller, any Seller Affiliate
         or any of other Affiliates to otherwise comply with or obtain more
         favorable treatment under any law or regulation or any accounting rule
         or principle; it being a condition to any such amendment that each
         Rating Agency will have notified the Indenture Trustee in writing that
         the amendment will not result in a reduction or withdrawal of the
         rating of any outstanding Notes or Certificates with respect to which
         it is a Rating Agency.

Indenture Trustee is hereby authorized to join in the execution of any such
supplemental indenture and to make any further appropriate agreements and
stipulations that may be therein contained.

                  (b) Issuer and Indenture Trustee, when authorized by an Issuer
Order, may, also without the consent of any of the Holders of the Notes but with
prior notice to the Rating Agencies by Issuer, as evidenced to Indenture
Trustee, enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to, or changing in any manner or eliminating
any of the provisions of, this Indenture or of modifying in any manner the
rights of

                                       39
<PAGE>   44

the Holders of the Notes under this Indenture; provided that such action shall
not, as evidenced by an Opinion of Counsel, adversely affect in any material
respect the interests of any Noteholder.

                  SECTION 9.2 Supplemental Indentures with Consent of
Noteholders.

                  (a) Issuer and Indenture Trustee, when authorized by an Issuer
Order, also may, with prior notice to the Rating Agencies and with the consent
of the Holders of not less than a majority of the Outstanding Amount of the
Notes, by Act of such Holders delivered to Issuer and Indenture Trustee, enter
into an indenture or indentures supplemental hereto for the purpose of adding
any provisions to, or changing in any manner or eliminating any of the
provisions of, this Indenture or of modifying in any manner the rights of the
Holders of the Notes under this Indenture; provided that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Note
affected thereby:

                  (i) change the date of payment of any installment of principal
         of or interest on any Note, or reduce the principal amount thereof, the
         interest rate thereon or the Redemption Price with respect thereto,
         change the provision of this Indenture relating to the application of
         collections on, or the proceeds of the sale of, the Trust Estate to
         payment of principal of or interest on the Notes, or change any place
         of payment where, or the coin or currency in which, any Note or the
         interest thereon is payable, or impair the right to institute suit for
         the enforcement of the provisions of this Indenture requiring the
         application of funds available therefor, as provided in Article V, to
         the payment of any such amount due on the Notes on or after the
         respective due dates thereof (or, in the case of redemption, on or
         after the Redemption Date);

                  (ii) reduce the percentage of the Outstanding Amount of the
         Notes, the consent of the Holders of which is required for any such
         supplemental indenture, or the consent of the Holders of which is
         required for any waiver of compliance with certain provisions of this
         Indenture or certain defaults hereunder and their consequences provided
         for in this Indenture;

                  (iii) modify or alter the provisions of the proviso as to the
         definition of the term "Outstanding";

                  (iv) reduce the percentage of the Outstanding Amount of the
         Notes required to direct Indenture Trustee to direct Issuer to sell or
         liquidate the Trust Estate pursuant to Section 5.4;

                  (v) modify any provision of this Section except to increase
         any percentage specified herein or to provide that certain additional
         provisions of this Indenture or the Basic Documents cannot be modified
         or waived without the consent of the Holder of each Outstanding Note
         affected thereby;

                  (vi) modify any of the provisions of this Indenture in such
         manner as to affect the calculation of the amount of any payment of
         interest or principal due on any Note on any Payment Date (including
         the calculation of any of the individual components of such

                                       40
<PAGE>   45

         calculation) or to affect the rights of the Holders of Notes to the
         benefit of any provisions for the mandatory redemption of the Notes
         contained herein; or

                  (vii) permit the creation of any lien ranking prior to or on a
         parity with the lien of this Indenture with respect to any part of the
         Trust Estate or, except as otherwise permitted or contemplated herein
         or in the Basic Documents, terminate the lien of this Indenture on any
         property at any time subject hereto or deprive the Holder of any Note
         of the security provided by the lien of this Indenture.

                  (b) Indenture Trustee may determine whether or not any Notes
would be affected by any supplemental indenture and any such determination shall
be conclusive upon the Holders of all Notes, whether theretofore or thereafter
authenticated and delivered hereunder. Indenture Trustee shall not be liable for
any such determination made in good faith.

                  (c) It shall not be necessary for any Act of Noteholders under
this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

                  (d) Promptly after the execution by Issuer and Indenture
Trustee of any supplemental indenture pursuant to this Section, Indenture
Trustee shall mail to the Holders of the Notes to which such amendment or
supplemental indenture relates a notice setting forth in general terms the
substance of such supplemental indenture. Any failure of Indenture Trustee to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such supplemental indenture.

                  SECTION 9.3 Execution of Supplemental Indentures. In
executing, or permitting the additional trusts created by, any supplemental
indenture permitted by this Article IX or the modifications thereby of the
trusts created by this Indenture, Indenture Trustee shall be entitled to
receive, and subject to Sections 6.1 and 6.2, shall be fully protected in
relying upon, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. Indenture
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture that affects Indenture Trustee's own rights, duties, liabilities or
immunities under this Indenture or otherwise.

                  SECTION 9.4 Effect of Supplemental Indenture. Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith with respect to the Notes affected thereby, and the respective rights,
limitations of rights, obligations, duties, liabilities and immunities under
this Indenture of Indenture Trustee, Issuer and the Holders of the Notes shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

                  SECTION 9.5 Conformity With Trust Indenture Act. Every
amendment of this Indenture and every supplemental indenture executed pursuant
to this Article IX shall conform to the requirements of the Trust Indenture Act
as then in effect so long as this Indenture shall then be qualified under the
Trust Indenture Act.

                  SECTION 9.6 Reference in Notes to Supplemental Indentures.
Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article IX may, and if required by Indenture Trustee
shall, bear a notation in form approved by Indenture Trustee as to any matter
provided for in such supplemental indenture. If Issuer or Indenture Trustee
shall so determine, new Notes so modified as to conform, in the opinion of
Indenture Trustee and Issuer, to any such supplemental indenture may be prepared
and executed by Issuer and authenticated and delivered by Indenture Trustee in
exchange for Outstanding Notes.

                         ARTICLE X REDEMPTION OF NOTES.

                  SECTION 10.1 Redemption. (a) The Class A-2 Notes are subject
to redemption in whole, but not in part, at the direction of Seller or Servicer
pursuant to Section 9.1(a) of the Sale and Servicing Agreement, on any Payment
Date on which Seller or Servicer exercises its option to purchase the Trust
Estate pursuant to said Section 9.1(a), for a purchase price equal to the
Redemption Price; provided that Issuer has available funds sufficient to pay the
Redemption Price. Servicer or Issuer shall furnish the Rating Agencies notice of
such redemption. If the Class A-2 Notes are to be redeemed pursuant to this
Section 10.1(a), Servicer or Issuer shall furnish notice of such election to
Indenture Trustee not later than 25 days prior to the Redemption Date and Issuer
shall deposit with Indenture Trustee in the Note Distribution Account the
Redemption Price of the Class A-2 Notes to be redeemed whereupon all such Class
A-2 Notes shall be due and payable on the Redemption Date upon the furnishing of
a notice complying with Section 10.2 to each Holder of the Class A-2 Notes.

                  (b) If the assets of Issuer are sold pursuant to Section 9.2
of the Trust Agreement, all amounts on deposit in the Note Distribution Account
shall be paid to the Noteholders up to the Outstanding Amount of the Notes and
all accrued and unpaid interest thereon. If amounts are to be paid to
Noteholders pursuant to this Section 10.1(b), Servicer or Issuer shall, to the
extent practicable, furnish notice of such event to Indenture Trustee not later
than 25 days prior to the Redemption Date whereupon all such amounts shall be
payable on the Redemption Date.

                  SECTION 10.2 Form of Redemption Notice. (a) Notice of
redemption under Section 10.1(a) shall be given by Indenture Trustee by
facsimile or by first-class mail, postage prepaid, transmitted or mailed prior
to the applicable Redemption Date to each Holder of Class A-2 Notes, as of the
close of business on the Record Date preceding the applicable Redemption Date,
at such Holder's address appearing in the Note Register.

                  All notices of redemption shall state:

                  (i) the Redemption Date;

                  (ii) the Redemption Price;

                  (iii) that the Record Date otherwise applicable to such
         Redemption Date is not applicable and that payments shall be made only
         upon presentation and surrender of such Class A-2 Notes and the place
         where such Class A-2 Notes are to be surrendered for

                                       42
<PAGE>   47

         payment of the Redemption Price (which shall be the office or agency of
         Issuer to be maintained as provided in Section 3.2); and

                  (iv) that interest on the Class A-2 Notes shall cease to
         accrue on the Redemption Date.

Notice of redemption of the Class A-2 Notes shall be given by Indenture Trustee
in the name and at the expense of Issuer. Failure to give notice of redemption,
or any defect therein, to any Holder of any Class A-2 Note shall not impair or
affect the validity of the redemption of any other Class A-2 Note.

                  (b) Prior notice of redemption under Section 10.1(b) is not
required to be given to Noteholders.

                  SECTION 10.3 Notes Payable on Redemption Date. The Class A-2
Notes to be redeemed shall, following notice of redemption as required by
Section 10.2 (in the case of redemption pursuant to Section 10.1(a)), on the
Redemption Date become due and payable at the Redemption Price and (unless
Issuer shall default in the payment of the Redemption Price) no interest shall
accrue on the Redemption Price for any period after the date to which accrued
interest is calculated for purposes of calculating the Redemption Price.

                           ARTICLE XI MISCELLANEOUS.

                  SECTION 11.1 Compliance Certificates and Opinions, etc. (a)
Upon any application or request by Issuer to Indenture Trustee to take any
action under any provision of this Indenture, Issuer shall furnish to Indenture
Trustee (i) an Officer's Certificate stating that all conditions precedent, if
any, provided for in this Indenture relating to the proposed action have been
complied with, (ii) an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent, if any, have been complied with and (iii)
(if required by the TIA) an Independent Certificate from a firm of certified
public accountants meeting the applicable requirements of this Section, except
that, in the case of any such application or request as to which the furnishing
of such documents is specifically required by any provision of this Indenture,
no additional certificate or opinion need be furnished. Every certificate or
opinion with respect to compliance with a condition or covenant provided for in
this Indenture shall include:

                  (i) a statement that each signatory of such certificate or
         opinion has read or has caused to be read such covenant or condition
         and the definitions herein relating thereto;

                  (ii) a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                  (iii) a statement that, in the opinion of each such signatory,
         such signatory has made such examination or investigation as is
         necessary to enable such signatory to express an informed opinion as to
         whether or not such covenant or condition has been complied with; and

                                       43
<PAGE>   48

                  (iv) a statement as to whether, in the opinion of each such
         signatory such condition or covenant has been complied with.

                  (b) Prior to the deposit of any Collateral or other property
or securities with Indenture Trustee that is to be made the basis for the
release of any property or securities subject to the lien of this Indenture,
Issuer shall, in addition to any obligation imposed in Section 11.1(a) or
elsewhere in this Indenture, furnish to Indenture Trustee an Officer's
Certificate certifying or stating the opinion of each person signing such
certificate as to the fair value (within 90 days of such deposit) to Issuer of
the Collateral or other property or securities to be so deposited.

                  (i) Whenever Issuer is required to furnish to Indenture
         Trustee an Officer's Certificate certifying or stating the opinion of
         any signer thereof as to the matters described in clause (i), Issuer
         shall also deliver to Indenture Trustee an Independent Certificate as
         to the same matters, if the fair value to Issuer of the securities to
         be so deposited and of all other such securities made the basis of any
         such withdrawal or release since the commencement of the then-current
         fiscal year of Issuer, as set forth in the certificates delivered
         pursuant to clause (i) and this clause (ii), is 10% or more of the
         Outstanding Amount of the Notes, but such a certificate need not be
         furnished with respect to any securities so deposited, if the fair
         value thereof to Issuer as set forth in the related Officer's
         Certificate is less than $25,000 or less than one percent of the
         Outstanding Amount of the Notes.

                  (ii) Other than with respect to the release of any Purchased
         Receivables or Defaulted Receivables, whenever any property or
         securities are to be released from the lien of this Indenture, Issuer
         shall also furnish to Indenture Trustee an Officer's Certificate
         certifying or stating the opinion of each person signing such
         certificate as to the fair value (within 90 days of such release) of
         the property or securities proposed to be released and stating that in
         the opinion of such person the proposed release will not impair the
         security under this Indenture in contravention of the provisions
         hereof.

                  (iii) Whenever Issuer is required to furnish to Indenture
         Trustee an Officer's Certificate certifying or stating the opinion of
         any signer thereof as to the matters described in clause (iii), Issuer
         shall also furnish to Indenture Trustee an Independent Certificate as
         to the same matters if the fair value of the property or securities and
         of all other property other than Purchased Receivables and Defaulted
         Receivables, or securities released from the lien of this Indenture
         since the commencement of the then current calendar year, as set forth
         in the certificates required by clause (iii) and this clause (iv),
         equals 10% or more of the Outstanding Amount of the Notes, but such
         certificate need not be furnished in the case of any release of
         property or securities if the fair value thereof as set forth in the
         related Officer's Certificate is less than $25,000 or less than one
         percent of the then Outstanding Amount of the Notes.

                  (iv) Notwithstanding Section 2.9 or any other provision of
         this Section, Issuer may (A) collect, liquidate, sell or otherwise
         dispose of Receivables as and to the extent permitted or required by
         the Basic Documents and (B) make cash payments out of the Trust
         Accounts as and to the extent permitted or required by the Basic
         Documents.

                                       44
<PAGE>   49

                  SECTION 11.2 Form of Documents Delivered to Indenture Trustee.

                  (a) In any case where several matters are required to be
certified by, or covered by an opinion of, any specified Person, it is not
necessary that all such matters be certified by, or covered by the opinion of,
only one such Person, or that they be so certified or covered by only one
document, but one such Person may certify or give an opinion with respect to
some matters and one or more other such Persons as to other matters, and any
such Person may certify or give an opinion as to such matters in one or several
documents.

                  (b) Any certificate or opinion of an Authorized Officer of
Issuer may be based, insofar as it relates to legal matters, upon a certificate
or opinion of, or representations by, counsel, unless such officer knows, or in
the exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his or her certificate or
opinion is based are erroneous. Any such certificate of an Authorized Officer or
Opinion of Counsel may be based, insofar as it relates to factual matters, upon
a certificate or opinion of, or representations by, an officer or officers of
Servicer, Seller, Administrator or Issuer, stating that the information with
respect to such factual matters is in the possession of Servicer, Seller,
Administrator or Issuer, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

                  (c) Where any Person is required to make, give or execute two
or more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

                  (d) Whenever in this Indenture, in connection with any
application or certificate or report to Indenture Trustee, it is provided that
Issuer shall deliver any document as a condition of the granting of such
application, or as evidence of Issuer's compliance with any term hereof, it is
intended that the truth and accuracy, at the time of the granting of such
application or at the effective date of such certificate or report (as the case
may be), of the facts and opinions stated in such document shall in such case be
conditions precedent to the right of Issuer to have such application granted or
to the sufficiency of such certificate or report. The foregoing shall not,
however, be construed to affect Indenture Trustee's right to rely upon the truth
and accuracy of any statement or opinion contained in any such document as
provided in Article VI.

                  SECTION 11.3 Acts of Noteholders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Noteholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Noteholders in person or by agents duly appointed in writing; and except as
herein otherwise expressly provided such action shall become effective when such
instrument or instruments are delivered to Indenture Trustee, and, where it is
hereby expressly required, to Issuer. Such instrument or instruments (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Noteholders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Indenture and (subject to

                                       45
<PAGE>   50

Section 6.1) conclusive in favor of Indenture Trustee and Issuer, if made in the
manner provided in this Section.

                  (b) The fact and date of the execution by any person of any
such instrument or writing may be proved in any customary manner of Indenture
Trustee.

                  (c) The ownership of Notes shall be proved by the Note
Register.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Notes shall bind the Holder
of every Note issued upon the registration thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by
Indenture Trustee or Issuer in reliance thereon, whether or not notation of such
action is made upon such Note.

                  SECTION 11.4 Notices, etc., to Indenture Trustee, Issuer and
Rating Agencies. Any request, demand, authorization, direction, notice, consent,
waiver or Act of Noteholders or other documents provided or permitted by this
Indenture to be made upon, given or furnished to or filed with:

                  (a) Indenture Trustee by any Noteholder, Administrator or
Issuer shall be sufficient for every purpose hereunder if personally delivered,
delivered by overnight courier or mailed certified mail, return receipt
requested and shall be deemed to have been duly given upon receipt to Indenture
Trustee at its Corporate Trust Office, or

                  (b) Issuer by Indenture Trustee or by any Noteholder shall be
sufficient for every purpose hereunder if personally delivered, delivered by
overnight courier or mailed certified mail, return receipt requested and shall
be deemed to have been duly given upon receipt to Issuer addressed to: Wells
Fargo Auto Trust 200__-__, in care of _____________________, with a copy to
Administrator at Wells Fargo Bank, N.A., 420 Montgomery Street, San Francisco,
California 94163, Attention: ______________, or at any other address previously
furnished in writing to Indenture Trustee by Issuer or Administrator. Issuer
shall promptly transmit any notice received by it from the Noteholders to
Indenture Trustee.

                  Notices required to be given to the Rating Agencies by Issuer,
Indenture Trustee or Owner Trustee shall be in writing, personally delivered,
delivered by overnight courier or mailed certified mail, return receipt
requested to (i) in the 56 case of Moody's, at the following address: Moody's
Investors Service, Inc., 99 Church Street, New York, New York 10004, (ii) in the
case of S&P, at the following address: Standard & Poor's Ratings Services, 26
Broadway (15th Floor), New York, New York 10004, Attention of Asset Backed
Surveillance Department; and (iii) in the case of Fitch, at the following
address: Fitch Investors Service, L.P., One State Street Plaza, New York, New
York 10004 or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

                  SECTION 11.5 Notices to Noteholders; Waiver.

                  (a) Where this Indenture provides for notice to Noteholders of
any event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class, postage prepaid to
each Noteholder affected by such event, at his address as it

                                       46
<PAGE>   51

appears on the Note Register, not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice. In any case
where notice to Noteholders is given by mail, neither the failure to mail such
notice nor any defect in any notice so mailed to any particular Noteholder shall
affect the sufficiency of such notice with respect to other Noteholders, and any
notice that is mailed in the manner herein provided shall conclusively be
presumed to have been duly given.

                  (b) Where this Indenture provides for notice in any manner,
such notice may be waived in writing by any Person entitled to receive such
notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Noteholders shall be filed with
Indenture Trustee but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such a waiver.

                  (c) In case, by reason of the suspension of regular mail
service as a result of a strike, work stoppage or similar activity, it shall be
impractical to mail notice of any event to Noteholders when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to Indenture Trustee shall
be deemed to be a sufficient giving of such notice.

                  (d) Where this Indenture provides for notice to the Rating
Agencies, failure to give such notice shall not affect any other rights or
obligations created hereunder, and shall not under any circumstance constitute a
Default or Event of Default.

                  SECTION 11.6 Alternate Payment and Notice Provisions.
Notwithstanding any provision of this Indenture or any of the Notes to the
contrary, Issuer may enter into any agreement with any Holder of a Note
providing for a method of payment, or notice by Indenture Trustee or any Paying
Agent to such Holder, that is different from the methods provided for in this
Indenture for such payments or notices, provided that such methods are
reasonable and consented to by Indenture Trustee (which consent shall not be
unreasonably withheld). Issuer will furnish to the trustee a copy of each such
agreement and Indenture Trustee will cause payments to be made and notices to be
given in accordance with such agreements.

                  SECTION 11.7 Conflict with Trust Indenture Act. If any
provision hereof limits, qualifies or conflicts with another provision hereof
that is required to be included in this indenture by any of the provisions of
the Trust Indenture Act, such required provision shall control. The provisions
of TIA Sections 310 through 317 that impose duties on any person (including the
provisions automatically deemed included herein unless expressly excluded by
this Indenture) are a part of and govern this Indenture, whether or not
physically contained herein.

                  SECTION 11.8 Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  SECTION 11.9 Successors and Assigns. All covenants and
agreements in this Indenture and the Notes by Issuer shall bind its successors
and assigns, whether so expressed or not. All agreements of Indenture Trustee in
this Indenture shall bind its successors.

                  SECTION 11.10 Severability. In case any provision in this
Indenture or in the Notes shall be invalid, illegal or unenforceable, the
validity, legality, and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

                  SECTION 11.11 Benefits of Indenture. Nothing in this Indenture
or in the Notes, express or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, and the Noteholders, and any
other party secured hereunder, and any other person with an ownership interest
in any part of the Trust Estate, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

                  SECTION 11.12 Legal Holidays. In any case where the date on
which any payment is due shall not be a Business Day, then (notwithstanding any
other provision of the Notes or this Indenture) payment need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

                  SECTION 11.13 GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING SECTION 5-1401
OF THE GENERAL OBLIGATIONS LAW, WITHOUT REFERENCE TO ITS CONFLICT OF LAW
PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

                  SECTION 11.14 Counterparts. This Indenture may be executed in
any number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the
same instrument.

                  SECTION 11.15 Recording of Indenture. If this Indenture is
subject to recording in any appropriate public recording offices, such recording
is to be effected by Issuer and at its expense accompanied by an Opinion of
Counsel (which may be counsel to Indenture Trustee or any other counsel
reasonably acceptable to Indenture Trustee) to the effect that such recording is
necessary either for the protection of the Noteholders or any other person
secured hereunder or for the enforcement of any right or remedy granted to
Indenture Trustee under this Indenture.

                  SECTION 11.16 Trust Obligation. No recourse may be taken,
directly or indirectly, with respect to the obligations of Issuer, Seller,
Servicer, Owner Trustee or Indenture Trustee on the Notes or under this
Indenture or any certificate or other writing delivered in connection herewith
or therewith, against (i) Seller, Servicer, Indenture Trustee or Owner Trustee
in its individual capacity, (ii) any owner of a beneficial interest in Issuer or
(iii) any partner, owner, beneficiary, agent, officer, director, employee or
agent of Seller, Servicer, Indenture Trustee or Owner Trustee in its individual
capacity, any holder of a beneficial interest in Issuer, Seller, Servicer, Owner
Trustee or Indenture Trustee or of any successor or assign of Seller, Servicer,
Indenture Trustee or Owner Trustee in its individual capacity, except as any
such Person may have expressly agreed (it being understood that Indenture
Trustee and Owner Trustee have no such obligations in their individual capacity)
and except that any such partner, owner or beneficiary shall be fully liable, to
the extent provided by applicable law, for any

                                       48
<PAGE>   53

unpaid consideration for stock, unpaid capital contribution or failure to pay
any installment or call owing to such entity. For all purposes of this
Indenture, in the performance of any duties or obligations of Issuer hereunder,
Owner Trustee shall be subject to, and entitled to the benefits of, the terms
and provisions of Article VI, VII and VIII of the Trust Agreement.

                  SECTION 11.17 No Petition. Indenture Trustee, by entering into
this Indenture, and each Noteholder, by accepting a Note, hereby covenant and
agree that they will not at any time institute against Seller or Issuer, or join
in any institution against Seller or Issuer of, any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings, or other proceedings under
any United States Federal or state bankruptcy or similar law in connection with
any obligations relating to the Notes, this Indenture or any of the Basic
Documents.

                  SECTION 11.18 Inspection. Issuer agrees that, on reasonable
prior notice, it will permit any representative of Indenture Trustee, during
Issuer's normal business hours, to examine all the books of account, records,
reports, and other papers of Issuer, to make copies and extracts therefrom, to
cause such books to be audited by Independent certified public accountants, and
to discuss Issuer's affairs, finances and accounts with Issuer's officers,
employees, and independent certified public accountants, all at such reasonable
times and as often as may be reasonably requested. Indenture Trustee shall and
shall cause its representatives to hold in confidence all such information
except to the extent disclosure may be required by law (and all reasonable
applications for confidential treatment are unavailing) and except to the extent
that Indenture Trustee may reasonably determine that such disclosure is
consistent with its obligations hereunder.

(including any successor, the "Issuer"), for value received, hereby promises to

__________________ DOLLARS ($___________), partially payable on each Payment
Date in an amount equal to the result obtained by multiplying (i) a fraction the
numerator of which is the initial principal amount of this Note and the
denominator of which is the aggregate initial principal amount of the Class A-1
Notes (the "Fraction") by (ii) the aggregate amount, if any, payable from the
Note Distribution Account in respect of principal on the A-1 Notes pursuant to
Section 3.1 of the Indenture; provided that the entire unpaid principal amount
of this Note shall be due and payable on the earlier of the Final Scheduled
Payment Date for the Class A-1 Notes and the Redemption Date, if any, pursuant
to Section 10.1 of the Indenture. The Issuer will pay interest on this Note on
each Payment Date until the principal of this Note is paid or made available for
payment, in an amount equal to the product of the Class A-1 Noteholders'
Interest Distributable Amount for the related Payment Date multiplied by the
Fraction subject to certain limitations contained in Section 3.1 and Section 8.2
of the Indenture. Such principal of and interest on this Note shall be paid in
the manner specified in the Indenture.

                  The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. All payments made by the
Issuer with respect to this Note shall be applied first to interest due and
payable on this Note as provided above and then to the unpaid principal of this

entitled to any benefit under the Indenture referred to on the reverse hereof,
or be valid or obligatory for any purpose.

                                [REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Notes of the
Issuer, designated as its ______% Class A-1 Asset Backed Notes (herein called
the "A-1 Notes" or the "Notes"), all issued under an Indenture dated as of
__________, 200__ (such Indenture, as supplemented or amended, is herein called
the "Indenture"), between the Issuer and _____________________, not in its
individual capacity but solely as trustee (the "Indenture Trustee"), which term
includes any successor Indenture Trustee under the Indenture, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement
of the respective rights and obligations thereunder of the Issuer, the Indenture
Trustee and the Holders of the Notes. The Notes are subject to all terms of the
Indenture. All terms used in this Note that are not otherwise defined herein and
that are defined in the Indenture shall have the meanings assigned to them in or
pursuant to the Indenture.

                  The Notes and the Class A-2 Notes are and will be equally and
ratably secured by the collateral pledged as security therefor as provided in
the Indenture.

                  The Issuer shall pay interest on overdue installments of
interest at the Class A-1 Interest Rate to the extent lawful.

                  Each Holder or Note Owner, by acceptance of a Note, or, in the
case of a Note Owner, a beneficial interest in the Note, covenants and agrees
that no recourse may be taken, directly or indirectly, with respect to the
obligations of Issuer, Seller, Servicer, Owner Trustee or Indenture Trustee on
the Notes or under this Indenture or any certificate or other writing delivered
in connection herewith or therewith, against (i) Seller, Servicer, Indenture
Trustee or Owner Trustee in its individual capacity, (ii) any owner of a
beneficial interest in Issuer or (iii) any partner, owner, beneficiary, agent,
officer, director, employee or agent of Seller, Servicer, Indenture Trustee or
Owner Trustee in its individual capacity, any holder of a beneficial interest in
Issuer, Seller, Servicer, Owner Trustee or Indenture Trustee or of any successor
or assign of Seller, Servicer, Indenture Trustee or Owner Trustee in its
individual capacity, except as any such Person may have expressly agreed (it
being understood that Indenture Trustee and Owner Trustee have no such
obligations in their individual capacity) and except that any such partner,
owner or beneficiary shall be fully liable, to the extent provided by applicable
law, for any unpaid consideration for stock, unpaid capital contribution or
failure to pay any installment or call owing to such entity.

                  It is the intent of the Seller, the Servicer, the Noteholders
and the Note Owners that, for purposes of Federal and State income tax and any
other tax measured in whole or in part by income, the Notes will qualify as
indebtedness of the Issuer. The Noteholders, by acceptance of a Note, agree to
treat, and to take no action inconsistent with the treatment of, the Notes for
such tax purposes as indebtedness of the Issuer.

                  Each Noteholder or Note Owner, by acceptance of a Note, or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that they will not at any time institute against Seller or Issuer, or join in
any institution against Seller or Issuer of, any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings, or other

<PAGE>   62

proceedings under any United States Federal or state bankruptcy or similar law
in connection with any obligations relating to the Notes, this Indenture or any
of the Basic Documents.

                  This Note and the Indenture shall be construed in accordance
with the laws of the State of New York, without reference to its conflict of law
provisions, and the obligations, rights and remedies of the parties hereunder
and thereunder shall be determined in accordance with such laws.

                  No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on
this Note at the times, place and rate, and in the coin or currency, herein
prescribed.

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither _________________, in its
individual capacity, any owner of a beneficial interest in the Issuer, nor any
of their respective partners, beneficiaries, agents, officers, directors,
employees, successors or assigns shall be personally liable for, nor shall
recourse be had to any of them for, the payment of principal of or interest on,
or performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture, it being expressly
understood that said covenants, obligations and indemnifications have been made
by the Owner Trustee for the sole purposes of binding the interests of the Owner
Trustee in the assets of the Issuer. The Holder of this Note by the acceptance
hereof agrees that, except as expressly provided in the Basic Documents, in the
case of an Event of Default under the Indenture, the Holder shall have no claim
against any of the foregoing for any deficiency, loss or claim therefrom;
provided that nothing contained herein shall be taken to prevent recourse to,
and enforcement against, the assets of the Issuer for any and all liabilities,
obligations and undertakings contained in the Indenture or in this Note.

                  Unless this Note is presented by an authorized representative
of The Depository Trust Company, a New York corporation ("DTC"), to the Issuer

OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner
hereof, Cede & Co., has an interest herein.

                  THE PRINCIPAL OF THIS NOTE IS PAYABLE IN INSTALLMENTS AS SET
FORTH HEREIN. ACCORDINGLY, THE OUTSTANDING PRINCIPAL AMOUNT OF THIS NOTE AT ANY

                       _____% CLASS A-2 ASSET BACKED NOTES

                  Wells Fargo Auto Trust 200__-__, a New York common law trust
(including any successor, the "Issuer"), for value received, hereby promises to
pay to CEDE & CO., or registered assigns, the principal sum of
__________________ DOLLARS ($___________), partially payable on each Payment
Date in an amount equal to the result obtained by multiplying (i) a fraction the
numerator of which is the initial principal amount of this Note and the
denominator of which is the aggregate initial principal amount of the Class A-2
Notes ("the Fraction") by (ii) the aggregate amount, if any, payable from the
Note Distribution Account in respect of principal on the A-2 Notes pursuant to
Section 3.1 of the Indenture; provided that the entire unpaid principal amount
of this Note shall be due and payable on the earlier of the Final Scheduled
Payment Date for the Class A-2 Notes and the Redemption Date, if any, pursuant
to Section 10.1 of the Indenture. No payments of principal of the A-2 Notes will
be made until the principal of the A-1 Notes has been paid in full. The Issuer
will pay interest on this Note on each Payment Date until the principal of this
Note is paid or made available for payment in an amount equal to the product of
the Class A-2 Noteholders' Interest distributable Amount for the related
Transfer Date multiplied by the Fraction, subject to certain limitations
contained in Section 3.1 and Section 8.2 of the Indenture. Such principal of and
interest on this Note shall be paid in the manner specified in the Indenture.

                  The principal of and interest on this Note are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and

private debts. All payments made by the Issuer with respect to this Note shall
be applied first to interest due and payable on this Note as provided above and
then to the unpaid principal of this Note.

                  Reference is made to the further provisions of this Note set
forth on the reverse hereof, which shall have the same effect as though fully
set forth on the face of this Note. Unless the certificate of authentication
hereon has been executed by the Indenture Trustee by manual signature, this Note
shall not be entitled to any benefit under the Indenture referred to on the
reverse hereof, or be valid or obligatory for any purpose.

                  IN WITNESS WHEREOF, the Issuer has caused this instrument to
be signed, manually or in facsimile, by its Authorized Officer.

                                [REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Notes of the
Issuer, designated as its ______% Class A-2 Asset Backed Notes (herein called
the "A-2 Notes" or the "Notes"), all issued under an Indenture dated as of
__________, 200__ (such Indenture, as supplemented or amended, is herein called
the "Indenture"), between the Issuer and _____________________, not in its
individual capacity but solely as trustee (the "Indenture Trustee"), which term
includes any successor Indenture Trustee under the Indenture, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement
of the respective rights and obligations thereunder of the Issuer, the Indenture
Trustee and the Holders of the Notes. The Notes are subject to all terms of the
Indenture. All terms used in this Note that are not otherwise defined herein and
that are defined in the Indenture shall have the meanings assigned to them in or
pursuant to the Indenture.

                  The Notes and the Class A-1 Notes are and will be equally and
ratably secured by the collateral pledged as security therefor as provided in
the Indenture.

                  The Issuer shall pay interest on overdue installments of
interest at the Class A-2 Interest Rate to the extent lawful.

                  Each Holder or Note Owner, by acceptance of a Note, or, in the
case of a Note Owner, a beneficial interest in the Note, covenants and agrees
that no recourse may be taken, directly or indirectly, with respect to the
obligations of Issuer, Seller, Servicer, Owner Trustee or Indenture Trustee on
the Notes or under this Indenture or any certificate or other writing delivered
in connection herewith or therewith, against (i) Seller, Servicer, Indenture
Trustee or Owner Trustee in its individual capacity, (ii) any owner of a
beneficial interest in Issuer or (iii) any partner, owner, beneficiary, agent,
officer, director, employee or agent of Seller, Servicer, Indenture Trustee or
Owner Trustee in its individual capacity, any holder of a beneficial interest in
Issuer, Seller, Servicer, Owner Trustee or Indenture Trustee or of any successor
or assign of Seller, Servicer, Indenture Trustee or Owner Trustee in its
individual capacity, except as any such Person may have expressly agreed (it
being understood that Indenture Trustee and Owner Trustee have no such
obligations in their individual capacity) and except that any such partner,
owner or beneficiary shall be fully liable, to the extent provided by applicable
law, for any unpaid consideration for stock, unpaid capital contribution or
failure to pay any installment or call owing to such entity.

                  It is the intent of the Seller, the Servicer, the Noteholders
and the Note Owners that, for purposes of Federal and State income tax and any
other tax measured in whole or in part by income, the Notes will qualify as
indebtedness of the Issuer. The Noteholders, by acceptance of a Note, agree to
treat, and to take no action inconsistent with the treatment of, the Notes for
such tax purposes as indebtedness of the Issuer.

                  Each Noteholder or Note Owner, by acceptance of a Note, or, in
the case of a Note Owner, a beneficial interest in a Note, covenants and agrees
that they will not at any time institute against Seller or Issuer, or join in
any institution against Seller or Issuer of, any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings, or other

<PAGE>   68

proceedings under any United States Federal or state bankruptcy or similar law
in connection with any obligations relating to the Notes, this Indenture or any
of the Basic Documents.

                  This Note and the Indenture shall be construed in accordance
with the laws of the State of New York, without reference to its conflict of law
provisions, and the obligations, rights and remedies of the parties hereunder
and thereunder shall be determined in accordance with such laws.

                  No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and interest on
this Note at the times, place and rate, and in the coin or currency, herein
prescribed.

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Basic Documents, neither ________________________, in
its individual capacity, any owner of a beneficial interest in the Issuer, nor
any of their respective partners, beneficiaries, agents, officers, directors,
employees, successors or assigns shall be personally liable for, nor shall
recourse be had to any of them for, the payment of principal of or interest on,
or performance of, or omission to perform, any of the covenants, obligations or
indemnifications contained in this Note or the Indenture, it being expressly
understood that said covenants, obligations and indemnifications have been made
by the Owner Trustee for the sole purposes of binding the interests of the Owner
Trustee in the assets of the Issuer. The Holder of this Note by the acceptance
hereof agrees that, except as expressly provided in the Basic Documents, in the
case of an Event of Default under the Indenture, the Holder shall have no claim
against any of the foregoing for any deficiency, loss or claim therefrom;
provided that nothing contained herein shall be taken to prevent recourse to,
and enforcement against, the assets of the Issuer for any and all liabilities,
obligations and undertakings contained in the Indenture or in this Note.
