the Banks, but is not obligated, to make Agent Advances consisting only of Prime
Rate Loans upon a Notice of Borrowing received by the Administrative Agent.
Agent Advances shall be subject to periodic settlement with the Banks under
Section 2.04. Any Agent Advance so made by the Administrative Agent shall
constitute part of the Obligations secured by the Collateral and shall be repaid
by the Company no later than the fifteenth (15th) day after the earliest date on
which any condition precedent to the making of a Loan set forth in Section 5.05
shall fail to be satisfied. Agent Advances may be made only in the following
circumstances:

          (i)   For administrative convenience and subject to Section 2.01, the
     Administrative Agent may, but is not obligated to, make Agent Advances in
     reliance upon the Company's actual or deemed representations under Section
     5.05 that the conditions for borrowing are satisfied;

          (ii)  If the conditions for borrowing under Section 5.05 cannot be
     fulfilled, the Company shall in its Notice of Borrowing or otherwise give
     immediate notice thereof to the Administrative Agent and the Banks and the
     Administrative Agent may, but is not obligated to, continue to make Agent
     Advances during the thirteen-day period beginning two (2) Business Days
     after receipt of such notice by the Administrative Agent, if the Company
     shall at such time be in compliance with the limitations set forth in
     Section 2.01; provided however, that the Majority Banks may sooner instruct
     the Administrative Agent to cease making such Agent Advances at any time.

The Administrative Agent may apply any payments or other amounts which it
receives to the repayment of the outstanding Agent Advances (beginning with the
oldest Agent Advance), prior to repayment of any other Loans, notwithstanding
any provision contained in any Loan Document or any direction of the Company or
any other Person to the contrary.

     (c)  Disbursement of Loans.  Loans, whether made as Bank Advances or Agent
Advances, subject to the terms and conditions of this Credit Agreement, will be
made as follows:

          (i)  It is contemplated that Loans be made available to reimburse an
     Issuing Bank for a drawing under a Letter of Credit, as described in
     Section 3.05, and such Loans may be made available by the Administrative
     Agent directly to an Issuing Bank upon notice from such Issuing Bank of
     such drawing.

          (ii) The Administrative Agent will make requested Loans available as
     instructed in a Notice of Borrowing.

     (d)  Notices of Borrowing; Minimum Amounts.  A Notice of Borrowing for
(i) Bank Advances of Prime Rate Loans shall be given not later than 1:00 P.M.,
New York City time, on the Business Day prior to the proposed Borrowing and (ii)
Agent Advances of Prime Rate Loans shall be given not later than 1:00 P.M., New
York City time, on the Business Day prior to the proposed Borrowing. A Notice of
Borrowing for Eurodollar Rate Loans shall be

                                      32
<PAGE>

given not later than 5:00 P.M., New York City time, on the third Business Day
prior to the proposed Borrowing.

          (A)  Notices of Borrowing may be given under this Section by
     telephone or facsimile transmission, and, if by telephone, promptly
     confirmed in writing. Once given, a Notice of Borrowing is irrevocable by
     and binding on the Company.

          (B)  The Company shall specify in each Notice of Borrowing whether the
     conditions for the requested Borrowing are satisfied and whether the
     requested Borrowing is of Prime Rate Loans or Eurodollar Rate Loans.  The
     Company may request one or more Borrowings on the same Business Day.  Each
     such Borrowing shall, unless otherwise specifically provided herein,
     consist entirely of Loans of the same Type and, if such Borrowing is to
     consist of Eurodollar Rate Loans, shall be in an aggregate amount for all
     Banks of not less than $5,000,000 or in an integral multiple of $1,000,000
     in excess thereof.  The right of the Company to choose Eurodollar Rate
     Loans is subject to the provisions of Section 4.07.

           (C)  On or prior to the Effective Date, the Company shall have
     provided to the Administrative Agent a list, with specimen signatures, of
     officers authorized to request Loans, substantially in the form attached to
     this Agreement as Exhibit A-1. The Administrative Agent is entitled to rely
     upon such list until it is replaced by the Company. The Administrative
     Agent shall have no duty to verify the authenticity of the signature
     appearing on any Notice of Borrowing or other writing delivered hereunder
     and, with respect to an oral request for Loans, the Administrative Agent
     shall have no duty to verify the identity of any individual representing
     himself as one of the officers authorized to make such request on behalf of
     the Company. Neither the Administrative Agent nor any of the Banks shall
     incur any liability to the Company as a result of acting upon any
     telephonic notice the Administrative Agent believes in good faith to have
     been given by a duly authorized officer or other individual authorized to
     request Loans on behalf of the Company or for otherwise acting in good
     faith with respect to any such request for Loans.

     2.03  Settlement of Bank.  The Administrative Agent shall give each Bank
prompt notice by telephone or facsimile Advances and Repayments transmission of
a Notice of Borrowing that requests Bank Advances of Loans and in any event
shall use its best efforts to notify each Bank on the same Business Day as
receipt of such Notice of Borrowing. No later than 2:00 P.M., New York City
time, on the date designated for the Borrowing, each Bank, for the account of
its applicable Lending Office, shall make available to the Administrative Agent
at the Administrative Agent's Payment Office its Pro Rata Share of such
Borrowing in immediately available funds. Unless the Administrative Agent
receives contrary written notice prior to the date of any such Borrowing of
Loans, it is entitled to assume that each Bank will make available its Pro Rata
Share of the Borrowing and in reliance upon that assumption, but without any
obligation to do so, may advance such Pro Rata Share on behalf of such Bank.

     2.04  Periodic Settlement of Agent and Bank Advances and Repayments.

     (a)   The Settlement Date.  The amount of each Bank's Pro Rata Share of
Loans shall be computed weekly (or more frequently in the Administrative Agent's
discretion) and shall be adjusted upward or downward based on all Loans
(including Agent Advances) and repayments of Loans received by the Agent as of
5:00 P.M., New York City time, on the last Business Day of the period specified
by the Administrative Agent (such date being referred to as the "Settlement
Date").

     (b)   Summary Statements; Settlements.

           (i)   The Administrative Agent shall deliver to each of the Banks
   promptly after the Settlement Date a summary statement of the amount of
   outstanding Loans (including Agent Advances) for the period and the amount of
   repayments received for the period. As reflected on the summary statement:
   (i) the Administrative Agent shall transfer to each Bank its allocated share
   of interest, Commitment Fees, Standby L/C Risk Participation Fees and
   Commercial L/C Risk Participation Fees, and its Pro Rata Share of repayments;
   and (ii) each Bank shall transfer to the Administrative Agent (as provided
   below), or the Administrative Agent shall promptly transfer to each Bank,
   such amounts as are necessary to insure that, after giving effect to all such
   transfers, the amount of Loans made by each Bank shall be equal to such
   Bank's Pro Rata Share of the aggregate amount of Loans outstanding as of such
   Settlement Date. If the summary statement requires transfers to be made to
   the Administrative Agent by the Banks and is received prior to 12:00 Noon,
   New York City time, on a Business Day, such transfers shall be made in
   immediately available funds no later than 3:00 P.M., New York City time, that
   day; and, if received after 12:00 Noon, New York City time, then no later
   than 3:00 P.M., New York City time on the next Business Day. The obligation
   of each Bank to transfer such funds is irrevocable, unconditional and without
   recourse to or warranty by the Administrative Agent. Each of the
   Administrative Agent and the Banks agree to mark their respective books and
   records on each Settlement Date to show at all times the Dollar amount of
   their respective Pro Rata Shares of the outstanding Loans.

           (ii)  To the extent that the Administrative Agent has made any such
   amounts available and the settlement described above shall not yet have
   occurred, upon repayment of Loans by the Company, the Administrative Agent
   may apply such amounts repaid directly to the amounts made available by the
   Administrative Agent pursuant to this Section 2.04(b).

     (c)  Distribution of Interest, Commitment Fees, Standby L/C Risk
Participation Fees and Commercial L/C Risk Participation Fees. Interest on the
Loans (including Agent Advances) together with the amount of the Commitment
Fees, Standby L/C Risk Participation Fees and Commercial L/C Risk Participation
Fees, shall be allocated by the Agent to each Bank in accordance with the Pro
Rata Share of Loans actually funded by and repaid to each Bank or such Bank's
Pro Rata Share of Letters of Credit outstanding, as applicable, and shall accrue
from and including the date such Loans are so advanced or such Letters of Credit
are issued and to but excluding the date such Loans are either repaid by the
Company or actually settled under this Section or such Letters of Credit are
drawn upon or expire or are canceled

                                      34
<PAGE>

(undrawn). Promptly after the end of each month (or, with respect to interest on
Eurodollar Rate Loans, promptly after such interest is received by the Agent),
the Agent shall distribute to each Bank its Pro Rata Share of the interest,
Commitment Fees, Standby L/C Risk Participation Fees and Commercial L/C Risk
Participation Fees accrued during that month.

     2.05  Defaulting Banks.

     (a)  A Bank who fails to pay the Administrative Agent its Pro Rata Share
of any Loans (including Agent Advances) made available by the Administrative
Agent on such Bank's behalf, or who fails to pay any other amount owing by it to
the Administrative Agent or any Issuing Bank (including, without limitation,
under Section 3.06), is a "Defaulting Bank." The Administrative Agent may
recover all such amounts owing by a Defaulting Bank on demand. If the Defaulting
Bank does not pay such amounts on the Administrative Agent's demand, the
Administrative Agent shall promptly notify the Company and the Company shall pay
such amounts within five Business Days. In addition, the Defaulting Bank or the
Company, as the case may be in accordance with the two immediately preceding
sentences, shall pay the Administrative Agent interest on such amount for each
day from the date it was made available by the Administrative Agent to the
Company to the date it is recovered by the Administrative Agent at a rate per
annum equal to (x) the overnight Federal Funds Rate, if paid by the Defaulting
Bank, or (y) the then applicable rate of interest calculated under Section 4.01,
if paid by the Company. Nothing herein shall be deemed to relieve any Bank from
its obligation to fulfill its commitments hereunder or to prejudice any rights
which the Company may have against any Bank as a result of any default by such
Bank hereunder, including, without limitation, the right of the Company to seek
reimbursement from any Defaulting Bank for any amounts paid by the Company under
clause (y) above on account of such Defaulting Bank's default.

     (b)  The failure of any Bank to fund its Pro Rata Share of any Loan
(including Agent Advances) shall not relieve any other Bank of its obligation to
fund its Pro Rata Share of such Loan. Conversely, no Bank shall be responsible
for the failure of another Bank to fund its Pro Rata Share of a Loan.

     (c)  Notwithstanding anything contained herein to the contrary, so long
as any Bank shall be in default in its obligation to fund its Pro Rata Share of
any Loan or shall have rejected its Commitment, then such Bank shall not be
entitled to receive any payments of principal of or interest on the Loans or its
share of any Commitment or other fees payable hereunder, and for purposes of
voting or consenting to matters with respect to the Loan Documents, such Bank
shall be deemed not to be a "Bank" hereunder, the combined Commitments then in
effect shall be reduced by an amount equal to such Bank's Commitment and such
Bank's Commitment shall be deemed to be zero (0), unless and until (x) (i) the
Loans and all interest thereon and all fees and other amounts owing under the
Loan Documents (other than amounts owing to such Bank) have been paid in full in
cash and (ii) the L/C Obligations shall have been repaid in full in cash and/or
collateralized in full in cash in such manner and order as shall be determined
by the Administrative Agent, (y) such failure to fulfill its obligation to fund
is cured and such Bank shall have paid, as and to the extent provided in this
Section 2.05, to the applicable party, if any, interest on the amount of funds
that such Bank failed to timely fund or (z) in respect of receiving payments but
not in respect of voting or consenting, the

                                      35
<PAGE>

Obligations under this Agreement shall have been declared or shall have become
immediately due and payable. No Commitment of any Bank shall be increased or
otherwise affected by any such failure or rejection by any other Bank. Any
payments of principal or interest which would, but for this paragraph, be paid
to any Bank, and which shall have been reimbursed by the Company to the
Administrative Agent pursuant to Section 2.05(a), shall be paid to the Banks who
shall not be in default under their respective Commitments and who shall not
have rejected any Commitment, for application to the Loans or to provide cash
collateral in such manner and order as shall be determined by the Administrative
Agent.

     2.06  Mandatory Payment; Reduction of Commitments.

     (a)  In the event that (i) the Effective Amount of all Loans then
outstanding exceeds the lesser of (x) $50,000,000 and (y) the combined
Commitments then in effect or (ii) the Effective Amount of all Loans then
outstanding plus the Effective Amount of all L/C Obligations plus the Effective
Amount of all Outstanding Eligible LOIs exceeds the lesser of (x) the combined
Commitments then in effect and (y) the Borrowing Base, then the Loans (subject
to the third sentence of Section 2.06(c)) shall be immediately due and payable
in the amount of such excess without the necessity of any demand, provided that
if there shall be no Loans then outstanding, the Company shall Cash
Collateralize outstanding Letters of Credit and Outstanding Eligible LOIs as
provided in Section 2.06(d) in an amount equal to such excess.

     (b)  The Company shall repay Loans to the extent necessary to ensure that
during the year 2000 there is a consecutive thirty (30) day period in which no
Loans are outstanding.

     (c)  On the Facility Expiry Date, the Commitment of each Bank shall
automatically reduce to zero and may not be reinstated. The Company may reduce
or terminate the Commitments at any time and from time to time in whole or in
part (a "Voluntary Reduction"). Each such Voluntary Reduction must be in an
amount not less than $5,000,000 (and in increments of $1,000,000 in excess
thereof). If the Company seeks to implement a Voluntary Reduction of the
combined Commitments to an amount less than $25,000,000, then the combined
Commitments shall be deemed reduced to zero and, at the option of the
Administrative Agent, all amounts hereunder shall be immediately due and
payable, provided, that the amount of each such Voluntary Reduction may not
reduce the combined Commitments to an amount equal to less than the sum of (i)
the Effective Amount of the Loans plus (ii) the Effective Amount of all L/C
Obligations plus (iii) the Effective Amount of all Outstanding Eligible LOIs
less, in the case of a Voluntary Reduction of the combined Commitments to zero,
the amount of Letters of Credit and Outstanding Eligible LOIs which are Cash
Collateralized in accordance with Section 2.06(d). Once reduced, no portion of
the Commitments may be reinstated.

     (d)  If any Letter of Credit is outstanding or there exists any Outstanding
Eligible LOIs upon the termination of the combined Commitments, or if at any
time there shall be any Loans, interest thereon or Commitment Fees, Standby
Letter of Credit fees, or Commercial Letter of Credit fees outstanding and
unpaid and the L/C Obligations shall be greater than the lesser of (i) the
Borrowing Base and (ii) the combined Commitments, the Company shall deposit with
the Administrative Agent, for the ratable benefit of the Banks, Cash

                                      36
<PAGE>

in the amount of all such Letters of Credit outstanding and Outstanding Eligible
LOIs upon such termination or the amount of such excess L/C Obligations and
Outstanding Eligible LOIs, as the case may be, which Cash shall be held as
collateral in an interest bearing account on terms satisfactory to the
Administrative Agent.

     2.07  Maintenance of Loan Account; Statements of Account.  The
Administrative Agent shall maintain an account on its books in the name of the
Company (the "Loan Account") in which the Company will be charged with all loans
and advances made by the Banks to the Company or for the Company's account,
including the Loans and all L/C Obligations, the Fees, the Expenses and any
other Obligations. The Loan Account will be credited with all amounts received
by the Administrative Agent from the Company or from others for the Company's
account, on the date received provided such amounts are received by no later
than 3:00 P.M., New York City time, and on the next Business Day if received
after such time. In no event shall prior recourse to any Collateral be a
prerequisite to the Administrative Agent's right to demand payment of any
Obligation upon its maturity. After the end of each month, the Administrative
Agent shall send the Company a statement accounting for the charges, loans,
advances and other transactions occurring among and between the Administrative
Agent, the Banks and the Company during that month. The monthly statements
shall, absent manifest error, be an account statement, which is final,
conclusive and binding on the Company; provided, however, that in respect of
Expenses that are, by the express terms of this Agreement required to be
reasonable, the Company reserves the right to assert that unreasonable Expenses
should not be so reimbursed.

     2.08  Payment Procedures.  Payments of interest, Fees and Expenses shall be
made not later than 2:00 P.M., New York City time, on the day when due, in
immediately available Dollars, to the Administrative Agent at its address
provided pursuant to Section 11.02 of this Agreement.  The Company hereby
authorizes the Administrative Agent to charge the Loan Account or any other
deposit account of the Company with the Administrative Agent with the amount of
all payments to be made hereunder and under the other Loan Documents, including
all Fees and Expenses, as and when such payments become due.  The Company's
obligations to the Banks with respect to such payments shall be discharged by
making such payments to the Administrative Agent pursuant to this Section or by
charging the Loan Account or such other deposit account.

     2.09  Cash Management System.  The Company shall during the term of this
Agreement maintain the existing cash management system including its network of
Lockbox, Collection Deposit Account and Concentration Account pursuant to the
Collection Bank Agreement and the Concentration Bank Agreement.

     2.10  Application of Payments.  All amounts received shall be credited to
the Loan Account for application to the Obligations in the following order:
first, to the payment of any Fees, Expenses or other Obligations due and payable
to the Collateral Agent and the Administrative Agent under any of the Loan
Documents, excluding Agent Advances; second, to the payment of interest due on
any Agent Advances and other amounts which have not been reimbursed to the
Administrative Agent by the Banks; third, to the payment of principal of Agent
Advances; fourth, to the payment of any Fees, expenses or other Obligations due
and payable to the Issuing Banks under any of the Loan Documents; fifth, to the
ratable payment of any Fees,

                                      37
<PAGE>

expenses or other Obligations due and payable to the Banks under any of the Loan
Documents other than those Obligations specifically referred to in this Section
2.10; sixth, to the ratable payment of interest due on the Loans; seventh, to
the ratable payment of principal due on the Loans; and eighth, to the Cash
Collateralization of outstanding Letters of Credit and Outstanding Eligible LOIs
in such manner and order as shall be determined by the Administrative Agent. Any
payment received hereunder as a distribution in any proceeding referred to in
Section 9.01(g) shall, unless paid with respect to amounts specifically owing to
the Administrative Agent or any Issuing Bank, be distributed and applied to the
payment of the amounts due hereunder and under the Notes ratably in accordance
with such amounts (or, if a court of competent jurisdiction shall otherwise
specify, as specified by such court).

     2.11  Increase of Commitments  .  The Company may at any time and from
time to time request that the aggregate Commitments under this Agreement be
increased by up to $160,000,000 ("Commitment Increase Amount"). In the event the
Company desires to increase the Commitments, the Company shall, (i) offer to the
Banks the opportunity to participate, pro rata, in all of the Commitment
Increase Amount and (ii) if the Banks decline to participate or participate for
less than the entire Commitment Increase Amount, with the consent of the
Administrative Agent in the case of banks, financial institutions or other
entities which are not Banks (which shall not be unreasonably withheld), offer
the Banks which accept such offer and one or more additional banks, financial
institutions or other entities the opportunity to participate in the remaining
portion of the Commitment Increase Amount. Any such increase shall become
effective upon the execution by the Company, the Administrative Agent and the
lender providing a portion of the Commitment Increase Amount (a "New Bank") of
an assumption agreement in form and substance reasonably satisfactory to the
Administrative Agent and the Company pursuant to which the New Bank becomes a
Bank under this Agreement and the other Loan Documents with respect to its
portion of the Commitment Increase Amount. This Agreement and the other Loan
Documents shall be deemed to be amended to reflect the Commitment Increase
Amount and the addition of the New Banks as Banks party hereto and thereto.

                                 Article III.

                               LETTERS OF CREDIT

     3.01  Issuance of Letters of Credit.  Subject to the terms and conditions
of this Agreement and in reliance upon the representations and warranties of the
Company set forth herein, each Issuing Bank shall issue Letters of Credit
hereunder at the request of the Company and for its account, as more
specifically described below. No Issuing Bank shall, in the case of clauses (a)
and (b) be permitted to, and in the case of clauses (c) and (d) be obligated to,
issue any Letter of Credit for the account of the Company if at the time of such
requested Issuance:

     (a)  the Effective Amount of all L/C Obligations plus the Effective Amount
of all Outstanding Eligible LOIs plus the Effective Amount of all Loans exceeds
the lesser of the combined Commitments then in effect and the Borrowing Base
then in effect, or the participation of any Bank in the Effective Amount of all
L/C Obligations plus the Effective Amount of the Loans of such Bank exceeds such
Bank's Commitment;

                                      38
<PAGE>

     (b)  the aggregate face amount of all Standby Letters of Credit issued for
any purpose other than for the purchase of inventory is at any time in excess of
the greater of (i) $50,000,000 less the maximum amount which may be drawn under
the External FW Letter of Credit and (ii) the maximum amount which may be drawn
under the FW Letter of Credit;

     (c)  Any order, judgment or decree of any Governmental Authority or
arbitrator shall purport by its terms to enjoin or restrain such Issuing Bank
from issuing such Letter of Credit or any Requirements of Law applicable to such
Issuing Bank or any request or directive (whether or not having the force of
law) from any Governmental Authority with jurisdiction over such Issuing Bank
shall prohibit, or request that the Issuing Bank refrain from, the issuance of
letters of credit generally or such Letter of Credit in particular or shall
impose upon such Issuing Bank with respect to such Letter of Credit any
restriction or reserve or capital requirement (for which such Issuing Bank is
not otherwise compensated) not in effect as of the Effective Date, or any
unreimbursed loss, cost or expense which was not applicable, in effect or known
to such Issuing Bank as of the Effective Date and which such Issuing Bank deems
in good faith to be material to it; or

     (d)  A default of any Bank's obligations to fund under Section 3.05
exists, or such Bank is a Defaulting Bank under Section 2.05, unless such
Issuing Bank has entered into satisfactory arrangements with the Company to
eliminate such Issuing Bank's risk with respect to such Bank, including Cash
Collateralization of such Bank's Pro Rata Share of the L/C Obligations in such
manner and order as the Administrative Agent shall determine.

     3.02  Terms of Letters of Credit; Existing Letters of Credit.

     (a)  The Letters of Credit shall be in a form customarily Issued by the
Issuing Bank or in such other form as has been approved by such Issuing Bank. At
the time of Issuance the terms and conditions of each Letter of Credit, and of
any drafts or acceptances thereunder, shall be subject to approval by the
Administrative Agent and the Company. In no event may the term of (i) any
Standby Letter of Credit (other than those referred to in (ii) below) issued
hereunder to purchase Inventory exceed 120 days (except that such Letters of
Credit may provide for automatic renewal), (ii) any other Standby Letter of
Credit exceed 365 days (except that such Letters of Credit may provide for
automatic renewal) or (iii) the term of any Commercial Letter of Credit exceed
90 days, and all Letters of Credit issued hereunder shall expire no later than
the date that is three (3) calendar days prior to the Facility Expiry Date. Any
Letter of Credit containing an automatic renewal provision shall also contain a
provision pursuant to which, notwithstanding any other provisions thereof, it
shall expire no later than the date that is three (3) calendar days prior to the
Facility Expiry Date and a provision pursuant to which the Issuing Bank may, by
notice to the beneficiary of such Letter of Credit at least sixty days (60)
prior to the expiration of its term, elect not to renew such Letter of Credit
for an additional term.

     (b)  All outstanding letters of credit issued under the Existing Credit
Agreement and set forth on Schedule 3.02 shall be deemed issued hereunder and
shall be, for all purposes, Letters of Credit hereunder.

     3.03  Banks' Participation.  Immediately upon Issuance or amendment by the
Issuing Bank of any Letter of Credit in accordance with the procedures set forth
in Section 3.01,

                                      39
<PAGE>

each Bank shall be deemed to have irrevocably and unconditionally purchased and
received from the Issuing Bank, without recourse or warranty, an undivided
interest and participation to the extent of such Bank's Pro Rata Share (based
upon its Commitment) in the liability with respect to such Letter of Credit
(including, without limitation, all obligations of the Company with respect
thereto, other than amounts owing to the Issuing Bank consisting of Issuing Bank
Fees) and any security therefor or guaranty pertaining thereto.

     3.04  Notice of Issuance.

     (a)  Whenever the Company desires the Issuance of a Letter of Credit, the
Company shall deliver (i) to the Issuing Bank a letter of credit application and
(ii) to Administrative Agent and to the applicable Issuing Bank, a L/C Request
no later than 2:00 P.M., New York City time, at least one (1) Business Day (or
such shorter period as may be agreed to by the Issuing Bank) in advance of the
proposed date of Issuance. The transmittal by the Company of each L/C Request
shall be deemed to be a representation and warranty by the Company that the
Letter of Credit may be Issued in accordance with and will not violate any of
the requirements of Section 3.01. Prior to the Issuance of each Letter of
Credit, the Company shall provide to the applicable Issuing Bank (with a copy to
the Administrative Agent) a precise description of the documents and the text of
any certificate to be presented by the beneficiary of such Letter of Credit
which, if presented by such beneficiary on or prior to the expiration date of
the Letter of Credit, would require such Issuing Bank to make payment under the
Letter of Credit. The Issuing Bank, in its reasonable judgment, may require
changes in any such documents and certificates. No Commercial Letter of Credit
shall require payment against a conforming document to be made thereunder prior
to the second Business Day (under the laws of the jurisdiction of the Issuing
Bank) after the date on which such document is presented, together with all
documents and/or certificates required to be presented in connection therewith
under the terms of the applicable Letter of Credit. A L/C Request and/or letter
of credit application may be given in writing or electronically and, if
requested by the Administrative Agent or the applicable Issuing Bank, with
prompt confirmation in writing. Any electronic L/C Request or letter of credit
application shall be deemed to have been prepared by, or under the supervision
of a Responsible Officer of the Company.

     (b)  When the Administrative Agent is not the Issuing Bank for all Letters
of Credit, then the other Issuing Banks are to send to the Administrative Agent
no later than 12:00 noon on each business day, by facsimile transmission, their
daily aggregate stated amount of Standby and Commercial Letters of Credit
balances for the previous day. The Agent shall deliver to each Bank upon each
calendar month end and concurrently with each Letter of Credit fee payment a
report setting forth for such period the daily aggregate stated amount available
to be drawn under Standby and Commercial Letters of Credit issued by all Issuing
Banks during such period.

     3.05  Payment of Amounts Drawn Under Letters of Credit.  In the event of
any drawing under any Letter of Credit by the beneficiary thereof, the
applicable Issuing Bank shall notify the Administrative Agent, which shall
notify the Company of such draw, not later than 11:00 A.M., New York City time,
on the day on which the Issuing Bank intends to honor such drawing. Unless the
Company shall, at the time of such drawing, have posted funds with such Issuing
Bank sufficient to reimburse such drawing in full in Cash, the Company will be
deemed

                                      40
<PAGE>

to have concurrently given a Notice of Borrowing to the Administrative Agent for
Prime Rate Loans in the amount of and at the time of such drawing.  Subject to
satisfaction or waiver of the conditions specified in Article 5 and the other
terms of and conditions to Borrowing contained herein, the Banks shall be
obligated, on the date of such drawing, to make Loans in the amount of such
drawing, the proceeds of which shall be applied directly by the Agent to
reimburse the applicable Issuing Bank for the amount of such drawing or payment.
If for any reason, proceeds of such Loans are not received by such Issuing Bank
on such date in an amount equal to the amount of such drawing, the Company shall
be obligated to and shall reimburse such Issuing Bank, on the Business Day
(under the laws of the jurisdiction of the Issuing Bank) immediately following
the date of such drawing, in an amount in immediately available funds equal to
the excess of the amount of such drawing over the amount of such Loans, if any,
which are so received, plus accrued interest on such amount at the rate set
forth in Section 4.01 of this Agreement.

     3.06  Payment by Banks.  If Loans are not made in an amount sufficient to
reimburse the applicable Issuing Bank in full for the amount of any draw, the
Administrative Agent shall promptly notify each Bank of the unreimbursed amount
of such drawing and of such Bank's respective participation therein.  Each Bank
shall make available to the Administrative Agent for the benefit of the
applicable Issuing Bank an amount equal to such Bank's respective participation
in immediately available funds, not later than 1:00 P.M., New York City time, on
the Business Day (under the laws of the jurisdiction of the Issuing Bank) after
the date notified by the Administrative Agent.  In addition, in the event that
any Bank fails to make available to the Administrative Agent the amount of any
such Bank's participation in such L/C Obligation as provided in this Section
3.06, the Administrative Agent may, but shall not be obligated to, fund the
amount of such Defaulting Bank's participation in such Letter of Credit and
recover such amount on demand from such Defaulting Bank in accordance with
Section 2.05 of this Agreement.  In the event that any Bank fails to make
available to the Administrative Agent the amount of such Bank's participation in
such Letter of Credit as provided in this Section 3.06, and the Administrative
Agent does not elect to fund to the Issuing Bank such Defaulting Bank's
participation in such Letter of Credit, the Issuing Bank shall be entitled to
recover such amount on demand from such Bank together with interest at the
Federal Funds Rate for the first three Business Days while such amount remains
unpaid and thereafter at the Prime Rate.  The Administrative Agent shall
distribute to each other Bank which has paid all amounts payable by it under
this Section 3.06 with respect to any Letter of Credit Issued by the applicable
Issuing Bank such other Bank's Pro Rata Share of all payments subsequently
received by the Administrative Agent from the Company in reimbursement of
drawings honored by the Issuing Bank under such Letter of Credit when such
payments are received.

     3.07  Nature of Issuing Bank's Duties.  In determining whether to pay under
any Letter of Credit, the applicable Issuing Bank shall be responsible only to
determine that the documents and certificates required to be delivered under
that Letter of Credit have been delivered and that they comply on their face
with the requirements of that Letter of Credit.  As between the Company, any
Issuing Bank and each other Bank, the Company assumes all risks of the acts and
omissions of such Issuing Bank (except to the extent that it is finally
judicially determined that such acts or omissions were the result of such
Issuing Bank's gross negligence or willful misconduct) or misuse of the Letters
of Credit by the respective beneficiaries of such Letters of Credit.  In
furtherance and not in limitation of the foregoing, neither the

                                      41
<PAGE>

Administrative Agent, any Issuing Bank nor any of the other Banks shall be
responsible (i) for the form, validity, sufficiency, accuracy, genuineness or
legal effects of any document submitted by any party in connection with the
application for and Issuance of or any drawing honored under such 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 any such 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
any such Letter of Credit to strictly comply 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, facsimile or otherwise, whether or not they be in cipher, (v) for errors
in interpretation of technical terms, (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any such Letter of Credit, or of the proceeds thereof, (vii) for the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of any drawing honored under such Letter of Credit, and (viii) for any
consequences arising from causes beyond the control of such Issuing Bank, the
Administrative Agent or the other Banks. The Issuing Bank shall not be obligated
to and shall not pay against any non-conforming documents presented to it in
connection with any Letters of Credit without the prior written consent of the
Company. None of the above shall affect, impair, or prevent the vesting of any
of the Issuing Bank's rights or powers hereunder. Any action taken or omitted to
be taken by the Issuing Bank under or in connection with any Letter of Credit,
if taken or omitted in the absence of gross negligence or willful misconduct,
shall not create for the Issuing Bank any liability to the Company, the
Administrative Agent or any Bank.

     3.08  Obligations Absolute.  The obligations of the Company to reimburse
the Issuing Bank for drawings honored under the Letters of Credit and the
obligations of the Banks under Section 3.06 shall be unconditional and
irrevocable and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances including, without limitation, the following
circumstances:

     (a)  any lack of validity or enforceability of any Letter of Credit;

     (b)  the existence of any claim, setoff, defense or other right which the
Company or any Affiliate of the Company may have at any time against a
beneficiary or any transferee of any Letter of Credit (or any Persons or
entities for whom any such beneficiary or transferee may be acting), the
applicable Issuing Bank, any Bank or any other Person, whether in connection
with this Agreement, the transactions contemplated herein or any unrelated
transaction;

     (c)  any draft, demand, certificate or any other documents presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect;

     (d)  the surrender or impairment of any security for the performance or
observance of any of the terms of any of the Loan Documents;

                                      42
<PAGE>

     (e)  payment by the Issuing Bank under any Letter of Credit against
presentation of a demand, draft or certificate or other document which does not
comply with the terms of such Letter of Credit;

     (f)  failure of any drawing under a Letter of Credit or any nonapplication
or misapplication by the beneficiary of the proceeds of any drawing; or

     (g)  the fact that a Default or an Event of Default shall have occurred
and be continuing;

provided, however, that the Company shall have no obligation to reimburse any
Issuing Bank, and the Banks shall have no obligation under Section 3.06, in the
event of such Issuing Bank's willful misconduct or gross negligence in
determining whether documents presented under the Letter of Credit comply with
the terms of such Letter of Credit.

      3.09  Uniform Customs and Practice and Uniform Commercial Code.  The
Uniform Customs and Practice for Documentary Credits as published by the
International Chamber of Commerce ("UCP") most recently at the time of Issuance
of any Letter of Credit shall (unless otherwise expressly provided in the
Letters of Credit) apply to the Letters of Credit. Without limiting the
foregoing, to the extent not addressed in the UCP, the UCC shall (unless
otherwise expressly provided in the Letters of Credit) apply to the Letters of
Credit.

                                  Article IV.

the Adjusted Eurodollar Rate for any Interest Period shall promptly notify the
Company and the Banks by telephone (confirmed promptly in writing) or in writing
thereof. Each determination by the Administrative Agent of an interest rate
under this Section 4.02 shall be conclusive and binding for all purposes, absent
manifest error.

     4.03  Interest After Event of Default.  Upon the occurrence and during
the continuation of an Event of Default resulting from the failure of the
Company to make any payment of principal or interest as provided in Section

such Loans, shall be payable on demand at a rate per annum equal to the rate at
which the Loans would bear interest pursuant to Sections 4.01 and 4.02 above, as
the case may be, plus two percent (2.00%). In the event of any change in said
applicable interest rate, the rate under this Section 4.03 shall change,
effective as of the day the applicable interest rate changes, so as to remain

     4.07  Special Provisions Relating to Eurodollar Rate Loans.

     (a)  Continuation.  With respect to any Borrowing consisting of
Eurodollar Rate Loans, the Company may (so long as no Default or Event of
Default has occurred and is continuing unless otherwise agreed to by the
Majority Banks), subject to the provisions of Section 4.07(c), elect to maintain
such Borrowing or any portion thereof as consisting of Eurodollar Rate Loans by
selecting a new Interest Period for such Borrowing, which new Interest Period
shall commence on the last day of the immediately preceding Interest Period.
Each selection of a new Interest Period shall be made by the giving of a Notice
of Continuation not later than 5:00 P.M., New York City time, on the third
Business Day prior to the date of any such continuation relating to Eurodollar
Rate Loans, by the Company to the Administrative Agent. Such Notice of
Continuation by the Company shall be by telephone or facsimile transmission, and
if by telephone, promptly confirmed in writing, in each case specifying (i) the
date of such continuation, (ii) the aggregate amount of Loans subject to such
continuation and (iii) the duration of the selected Interest Period. The Company
may elect to maintain more than one Borrowing consisting of Eurodollar Rate
Loans by combining such Borrowings into one Borrowing and selecting a new
Interest Period pursuant to this Section 4.07(a); provided, however, that each
of the Borrowings so combined shall consist of Loans having Interest Periods
ending on the same date. If the Company shall fail to select a new Interest
Period for any Borrowing consisting of Eurodollar Rate Loans in accordance with
this Section 4.07(a), such Loans will automatically on the last day of the then
existing Interest Period therefor, convert into Prime Rate Loans.

     (b)  Conversion.  The Company may on any Business Day (so long as no
Default or Event of Default has occurred and is continuing unless otherwise
agreed to by the Majority Banks), upon the giving of a Notice of Conversion
given to the Administrative Agent, and subject to the provisions of Section
4.07(c), convert the entire amount of or a portion of all Loans of one Type
comprising the same Borrowing into Loans of another Type; provided, however,
that any conversion of any Eurodollar Rate Loans into Prime Rate Loans shall be
made on, and only on, the last day of an Interest Period for such Eurodollar
Rate Loans and, upon conversion of any Prime Rate Loans into Eurodollar Rate
Loans, the Company shall pay accrued interest to the date of conversions on the
principal amount converted. Each such Notice of Conversion shall be given not
later than 1:00 P.M., New York City time, on the day of any proposed conversion
into Prime Rate Loans and not later than 5:00 P.M. on the third Business Day
prior to the date of any proposed conversion into Eurodollar Rate Loans. Subject
to the restrictions specified above, each Notice of Conversion shall be by
telephone or facsimile transmission and, if by telephone, promptly confirmed in
writing, in each case specifying (i) the requested date of such conversion, (ii)
the Type of Loans to be converted, (iii) the portion of such Type of Loan to be
converted, (iv) the Type of Loan such Loans are to be converted into and (v) if
such conversion is into Eurodollar Rate Loans, the duration of the Interest
Period of such Loan. Each conversion shall be in an aggregate amount for the
Loans of all Banks of not less than $5,000,000 or in an integral multiple of
$1,000,000 in excess thereof. The Company may elect to convert the entire amount
of or a portion of all Loans of one Type comprising more than one Borrowing into
Loans of another Type by combining such Borrowings into one

                                      46
<PAGE>

Borrowing consisting of Loans of another Type; provided, however, that if the
Borrowings so combined consist of Eurodollar Rate Loans, such Loans shall have
Interest Periods ending on the same date.

     (c)  Certain Limitations on Eurodollar Rate Loans. The right of the
Company to maintain, select, continue or convert Eurodollar Rate Loans shall be
limited as follows:

          (i)    If the Administrative Agent is advised by BT that it is not
     offering U.S. dollar deposits (in the applicable amounts) in the London
     interbank market, or the Administrative Agent determines that adequate and
     fair means do not otherwise exist for ascertaining the Eurodollar Rate for
     Eurodollar Rate Loans comprising any requested Borrowing, continuation or
     conversion, the right of the Company to select or maintain Eurodollar Rate
     Loans for such Borrowing or any subsequent Borrowing shall be suspended
     until the Administrative Agent shall notify the Company and the Banks that
     the circumstances causing such suspension no longer exist, and each Loan
     comprising such Borrowing shall be made as a Prime Rate Loan.

           (ii)  If the Majority Banks shall, at least one Business Day before
     the date of any requested Borrowing of, continuation of or conversion into
     a Eurodollar Rate Loan, notify the Administrative Agent that the Eurodollar
     Rate for Loans comprising such Borrowing, continuation or conversion will
     not adequately reflect the cost to such Banks of making or funding their
     respective Loans for such Borrowing or conversion, or maintaining such
     continuation, the right of the Company to select or continue Eurodollar
     Rate Loans for such Borrowing, continuation or conversion shall be
     suspended until such Banks shall notify the Company and Administrative
     Agent that the circumstances causing such suspension no longer exist, and
     each Loan comprising such Borrowing, continuation or conversion shall be
     made as a Prime Rate Loan.

          (iii)  If at any time any Bank determines  (which determination
     shall, absent manifest error, be conclusive and binding on all parties)
     that the making, continuation or conversion of any Loan as a Eurodollar
     Rate Loan has become unlawful or impermissible by reason of compliance by
     that Bank with any law, governmental rule, regulation or order of any
     Governmental Authority (whether or not having the force of law or would
     result in costs or penalties), then, and in any such event, such Bank may
     give notice of that determination, in writing, to the Company and the
     Administrative Agent and the Administrative Agent shall promptly transmit
     the notice to each other Bank. Until such Bank gives notice otherwise, the
     right of the Company to select Eurodollar Rate Loans from that Bank shall
     be suspended and each Eurodollar Rate Loan outstanding from that Bank shall
     automatically and immediately convert to a Prime Rate Loan.

          (iv)   No Agent Advance shall be made as a Eurodollar Rate Loan.

          (v)    The right of the Company to select, continue or convert
     Eurodollar Rate Loans shall not be effective during the continuance of any
     Default or Event of Default unless otherwise agreed to by the Majority
     Banks.

                                      47
<PAGE>

          (vi) There shall not be outstanding at any one time more than an
     aggregate of five (5) Loans which consist of Eurodollar Rate Loans.

     (d)  Compensation.

          (i)    Each Notice of Continuation and Notice of Conversion shall be
     irrevocable by and binding on the Company. In the case of any Borrowing,
     continuation or conversion that the related Notice of Borrowing, Notice of
     Continuation or Notice of Conversion specifies is to be comprised of
     Eurodollar Rate Loans, the Company shall indemnify each Bank against any
     loss, cost or expense incurred by such Bank as a result of any failure to
     fulfill, on or before the date for such Borrowing, continuation or
     conversion specified in such Notice of Borrowing, Notice of Continuation or
     Notice of Conversion, the applicable conditions set forth in Article 5 or,
     in the event such conditions are satisfied, the failure of the Company to
     make such Borrowing, including, without limitation, in each case any loss
     (excluding loss of anticipated profits), cost or expense incurred by reason
     of the liquidation or reemployment of deposits or other funds acquired by
     such Bank to fund the Loan to be made by such Bank as part of such
     Borrowing, continuation or conversion.

          (ii)   If any payment of principal of, or conversion or continuation
     of, any Eurodollar Rate Loan is made other than on the last day of the
     Interest Period for such Loan as a result of a payment, prepayment,
     conversion or continuation of such Loan or acceleration of the maturity of
     the Notes pursuant to Article 9 of this Agreement or for any other reason,
     the Company shall, upon demand by any Bank (with a copy of such demand to
     the Administrative Agent), pay to the Administrative Agent for the account
     of such Bank any amounts required to compensate such Bank for any
     additional losses, costs or expenses which it may reasonably incur as a
     result of such payment, including, without limitation, any loss (excluding
     loss of anticipated profits), cost or expense incurred by reason of the
     liquidation or reemployment of deposits or other funds acquired by any Bank
     to fund or maintain such Loan.

          (iii)  Calculation of all amounts payable to a Bank under this
     Section 4.07(d) shall be made as though such Bank elected to fund all
     Eurodollar Rate Loans by purchasing U.S. dollar deposits in its Eurodollar
     Lending Office's interbank eurodollar market.

     4.08  Indemnification in Certain Events.

     (a)  If after the Effective Date, either (i) any change in or in the
interpretation of any law or regulation is introduced, including, without
limitation, with respect to reserve requirements, applicable to BT, any Bank or
any Affiliate controlling any Bank, or (ii) a Bank or an Affiliate controlling a
Bank complies with any future guideline or request from any central bank or
other Governmental Authority and in the case of any event described in clause
(i) or (ii) such event increases the cost to BT, of issuing, making or
maintaining the Letter of Credit or complying with its obligations under this
Agreement or reduces the amount receivable in respect thereof by BT or such
Affiliate, or (iii) a Bank or an Affiliate controlling a Bank determines that
the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change

                                      48
<PAGE>

therein, or any change in the interpretation or administration thereof by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof has or would have the effect described
below or, a Bank or an Affiliate controlling a Bank complies with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, and in the case of any
event set forth in this clause (iii), such adoption, change or compliance has or
would have the direct or indirect effect of reducing the rate of return on any
of the capital as a consequence of its obligations hereunder to a level below
that which a Bank or an Affiliate controlling a Bank could have achieved but for
such adoption, change or compliance (taking into consideration such Bank's or
Affiliate's policies as the case may be with respect to capital adequacy) by an
amount deemed by such Bank or such Affiliate controlling such Bank to be
material, then in any such case, the Company shall, upon demand by the Agent,
pay to the Administrative Agent, for the account of each applicable Bank, each
applicable Affiliate controlling a Bank or, each applicable Issuing Bank,
additional amounts sufficient to indemnify such Bank or the Affiliate
controlling such Bank against such increase in cost or reduction in amount
receivable. A certificate as to the amount of such increased cost or reduction
in amount and setting forth in reasonable detail the calculation thereof shall
be submitted to the Company by the Administrative Agent, or the applicable Bank
or the applicable Affiliate controlling such Bank, and shall be conclusive,
absent manifest error. Any party entitled to payment hereunder in respect of
such increased cost or reduction in amount shall use reasonable efforts to
designate a different Lending Office to the extent such designation could reduce
or eliminate such payment.

     (b)   It is understood that (i) Section 4.08(a) does not relate to any
changes in the rate of tax on the net income of the Issuing Bank, or any Bank,
or any Affiliate controlling such Bank imposed by the jurisdiction in which it
is organized, maintains a lending office or its principal office, or has any
other contacts or connections that would subject it to taxation therein
(excluding any connection or contact arising solely from the Issuing Bank, or
such Bank or such Affiliate having executed, delivered, performed its
obligations or received a payment under, or enforced this Agreement or any other
Loan Document) and (ii) any payment made under this Section 4.08 shall be made
without duplication for any item that is covered by Section 4.09.

     4.09  Net Payments.

     (a)   All payments by the Company hereunder or under any other Loan
Document to or for the benefit of any Bank, any Issuing Bank, the Collateral
Agent or the Administrative Agent shall be made without set-off, counterclaim or
other defense and shall be made free and clear of, and without deduction or
withholding for, any Taxes. In addition, the Company shall pay all Other Taxes.

     (b)   The Company agrees to indemnify and hold harmless each Bank, the
Issuing Bank, the Collateral Agent and the Administrative Agent for the full
amount of Taxes or Other Taxes (including any additional Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section 4.09(b)) paid
by any Bank, any Issuing Bank, the Collateral Agent or the Administrative Agent
in respect of any sum payable hereunder or under any other Loan Document
(including penalties, interest, additions to tax and any reasonable expenses).

                                      49
<PAGE>

     (c)  Payment under this indemnification shall be made within 30 days after
the date any Bank, any Issuing Bank, the Collateral Agent or the Administrative
Agent makes written demand therefor.

     (d)  If the Company shall be required by law to deduct or withhold any
Taxes or Other Taxes from or in respect of any sum payable hereunder (or under
any other Loan Document) to any Bank, any Issuing Bank, the Collateral Agent or
the Administrative Agent, then:

          (i)    the sum payable shall be increased as necessary so that after
     making all such required deductions and withholdings of Taxes or Other
     Taxes (including deductions and withholdings applicable to additional sums
     payable under this Section 4.09), such Bank, such Issuing Bank, the
     Collateral Agent or the Administrative Agent receives an amount equal to
     the sum it would have received had no such deductions or withholdings been
     made;

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

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

     (e)  Within 30 days after the date of any payment by the Company of Taxes
or Other Taxes, the Company shall furnish to the Administrative Agent the
original or a certified copy of a receipt evidencing payment thereof, or other
evidence of payment satisfactory to the Administrative Agent if available from
the appropriate taxing authority.

     (f)  If the Company would be required to pay additional amounts to any Bank
pursuant to paragraph (b) or (c) of this Section 4.09, then such Bank shall use
reasonable efforts (consistent with legal and regulatory restrictions) to change
the jurisdiction of its lending office so as to eliminate the obligation of the
Company to pay any such additional amounts which may thereafter accrue or to
indemnify such Bank in the future, if such change in the reasonable judgment of
such Bank is not otherwise materially disadvantageous to such Bank.

     (g)  (i) Any Bank not organized under the laws of the United States shall
furnish to the Company or the Administrative Agent, two copies of IRS Form W-
8BEN or W-8ECI, or successor applicable form (which shall be accurate and
complete) as may be required to establish, as of the date of this Agreement, an
exemption from U.S. withholding taxes or backup withholding taxes in respect of
payments made under any Loan Document. In the event that a Bank assigns all or a
portion of its rights and obligations under this Agreement, pursuant to Section
11.07, each assignee shall furnish to the Company or the Administrative Agent
two copies of IRS Form W-8BEN or W-8ECI, or successor applicable form (which
shall be accurate and complete) as may be required to establish, as of the date
of the assignment, a full exemption from U.S. withholding taxes or back-up
withholding taxes in respect of payments made under this Agreement. The Company
and the Administrative Agent shall be entitled to rely upon the accuracy of any
such forms, documents or other information furnished to it by any Person and
shall have no obligation to make any additional payment or indemnify any Person
for any taxes,

                                      50
<PAGE>

interest or penalties that would not have become payable by such Person had such
documentation been accurate.

          (ii) Each Bank that is not organized under the laws of the United
     States (including any assignee pursuant to Section 11.07 that is not
     organized under the laws of the United States) shall also deliver to the
     Company or the Administrative Agent two further copies of said Form W-8BEN
     or W-8ECI, or successor applicable forms, as the case may be, when
     requested to do so by the Company or the Administrative Agent on or before
     the date that any such form expires or becomes obsolete or otherwise is
     required to be resubmitted as a condition to obtaining an exemption from a
     required withholding of U.S. federal income tax or after the occurrence of
     any event requiring a change in the most recent form previously delivered
     by it to the Administrative Agent or the Company, and such extensions or
     renewals thereof as may reasonably be requested by the Company or the
     Administrative Agent, certifying that such Bank is entitled to receive
     payments hereunder or under any other Loan Documents without deduction or
     withholding of any U.S. federal income taxes or at a reduced rate, unless
     in any such case an event outside the control of such Bank (including,
     without limitation, any change in treaty, law or regulation) has occurred
     prior to the date on which any such delivery would otherwise be required
     which renders all such forms inapplicable or which would prevent such Bank
     from duly completing and delivering any such form with respect to it and
     such Bank so advises the Company or the Administrative Agent. No Bank shall
     be required to provide a form described in the preceding sentence unless it
     is legally entitled to do so at the time such form is requested by the
     Company.

     (h)  The Company shall not be required to pay any additional amounts
pursuant to this Section 4.09 to the extent that such additional amounts relate
to Taxes or Other Taxes (including obligations to deduct or withhold amounts
with respect thereto) for any period (i) that would not have been imposed but
for the failure of a Bank or any assignee thereof, to comply with Section
4.09(f) hereof (other than if such failure is due to a change in law, regulation
or treaty occurring after the date on which a form originally was required to be
provided) or (ii) that are attributable to U.S. withholding taxes imposed (x) on
the date the Bank becomes a Lender under this Agreement or (y) other than as a
result of a change in law, regulation or treaty. If a Bank becomes subject to
Taxes because of its failure to deliver a form required hereunder, the Company
shall take such steps as the Bank shall reasonably request to assist such Bank
to recover such Taxes.

     4.10  Affected Banks.  If the Company is obligated to pay to any Bank or an
Issuing Bank any amount under Section 4.08 or 4.09 or if any Bank is a
Defaulting Bank, the Company may, if no Default or Event of Default then exists,
replace such Bank with another bank or may replace such Issuing Bank with
another letter of credit issuer in each case acceptable to the Administrative
Agent and the Issuing Banks (other than such Issuing Bank), and such Bank or
such Issuing Bank, as applicable, hereby agrees to be so replaced subject to the
following:

     (a)  The obligations of the Company hereunder to the Bank or the Issuing
Bank to be replaced (including such increased or additional costs incurred from
the date of notice to the Company of such increase or additional costs through
the date such Bank or Issuing Bank

                                      51
<PAGE>

is replaced hereunder) shall be paid in full in cash to such Bank or Issuing
Bank concurrently with such replacement;

     (b)  If such replacement is a result of increased costs under Section 4.08
or 4.09, the replacement Bank shall be a bank or other financial institution
acceptable to the Administrative Agent that is not subject to such increased
costs which caused the Company's election to replace any Bank hereunder, and
such replacement Bank shall execute and deliver to the Administrative Agent such
documentation satisfactory to the Administrative Agent pursuant to which such
replacement Bank is to become a party to this Agreement, conforming to the
provisions of Section 11.07, with a Commitment equal to that of the Bank being
replaced, shall make Loans in the aggregate principal amount equal to the
aggregate outstanding principal amount of the Loans of the Bank being replaced
and shall be deemed to have acquired a participation in L/C Obligations then
outstanding equal to the participation therein of the Bank being replaced;

     (c)  Upon such execution and delivery of such documents referred to in
clause (b) and payment of the amounts referred to in clause (a), the replacement
bank shall be a "Bank" with a Commitment as specified hereinabove and the Bank
being replaced shall cease to be a "Bank" hereunder, except with respect to
indemnification provisions under this Credit Agreement, which shall survive as
to such replaced Bank;

     (d)  The Administrative Agent shall reasonably cooperate in effectuating
the replacement of any Bank or any Issuing Bank under this Section 4.10, but at
no time shall the Administrative Agent be obligated to initiate any such
replacement;

     (e)  Any Bank or the Issuing Bank replaced under this Section 4.10 shall be
replaced at the Company's sole cost and expense and at no cost or expense to the
Administrative Agent or any of the Banks or the Issuing Bank; and

     (f)  If the Company proposes to replace any Bank pursuant to this Section
4.10 because the Bank seeks reimbursement under either Section 4.08 or 4.09,
then it must also replace any other Bank who seeks reimbursement on a
proportionate basis (based upon such Bank's Commitment to the combined
Commitments) under such Sections.

     4.11  Sharing of Payments.  If any Bank shall obtain any payment (whether
voluntary, involuntary, through the exercise of any right of set-off or
otherwise) on account of the Loans made by it or its participation in the L/C
Obligations in excess of its Pro Rata Share of payments on account of the Loans
or L/C Obligations obtained by all the Banks, such Bank shall forthwith purchase
from the other Banks such participations in the Loans made by them or in their
participation in Letters of Credit as shall be necessary to cause such
purchasing Bank to share the excess payment ratably with each of them; provided,
however, that if all or any portion of such excess payment is thereafter
recovered from such purchasing Bank, such purchase (or corresponding portion
thereof) from each Bank shall be rescinded and each such Bank shall repay to the
purchasing Bank the purchase price to the extent of such recovery together with
an amount equal to such Bank's ratable share (according to the proportion of (i)
the amount of such Bank's required repayment to (ii) the total amount so
recovered from the purchasing Bank) of any interest or other amount paid or
payable by the purchasing Bank in respect to the total

                                      52
<PAGE>

amount so recovered. The Company agrees that any Bank so purchasing a
participation from another Bank pursuant to this Section 4.11 may, to the full
extent permitted by law, exercise all of its rights of payment (including the
right of setoff) with respect to such participation as fully as if such Bank
were the direct creditor of the Company in the amount of such participation.

     4.12  Calculations.  All calculations of (i) interest with respect to
Eurodollar Rate Loans and per annum fees, shall be made by the Administrative
Agent, on the basis of a year of 360 days, or, if such computation would cause
the interest and fees chargeable hereunder to exceed the highest rate allowed by
applicable law, 365/366 days, and (ii) interest with respect to Prime Rate Loans
shall be made by the Administrative Agent on the basis of a year of 365/366
days, in each case to the extent applicable for the actual number of days
elapsed (including the first day but excluding the last day) occurring in the
period for which such interest or fees are payable.  Each determination by the
Administrative Agent of an interest rate or payment hereunder shall be
conclusive and binding for all purposes, absent manifest error.

Effect.

     6.02 Corporate Authorization; No Contravention  .  The execution,
delivery and performance by the Company and the Restricted Subsidiaries of each
Loan Document to which such Person is party, have been duly authorized by all
necessary corporate (or equivalent) action, and do not and will not:

enforcement against, the Company or any of its Restricted Subsidiaries of any
Loan Document to which such Person is a party.

     6.04 Binding Effect  .  Each Loan Document to which the Company or any of
its Restricted Subsidiaries is a party constitutes the legal, valid and binding
obligation of the Company and its Restricted Subsidiaries to the extent it is a

     (a)  Each Plan is in compliance in all respects with the applicable
provisions of ERISA, the Code and other federal or state law, except for matters
which have not resulted and
                                      60
<PAGE>

would not reasonably be expected to result in a Material Adverse Effect. Each
Plan which is intended to qualify under Section 401(a) of the Code has received,
or will timely file for, a favorable determination letter from the IRS and to
the best knowledge of the Company, nothing has occurred which would cause, or

Plans, and no application for a funding waiver or an extension of any
amortization period pursuant to Section 412 of the Code has been made with
respect to any Plan.

or 4243 of ERISA with respect to a Multiemployer Plan and any material liability
that could reasonably be expected to result from the operation of Section 4069
or 4212(c) of ERISA.

     6.08 Use of Proceeds; Margin Regulations  . The proceeds of the Loans are
to be used solely for the purposes set forth in and permitted by Section 7.11

purpose of purchasing or carrying Margin Stock.

record and marketable title in fee simple to, or
valid leasehold interests in, all real property necessary or used in the
ordinary conduct of their respective businesses, except for such defects in

otherwise due and payable, except those which are being contested in good faith
by appropriate proceedings and for which adequate reserves have been provided in
accordance with GAAP. There is no proposed tax assessment against the Company or
any of its Subsidiaries that would, if made, reasonably be expected to have a

immediately due and payable, and declare the unpaid principal amount of all
outstanding Loans, all interest accrued and unpaid thereon, and all other

to make Loans and any obligation of any Issuing Bank to Issue Letters of Credit
shall automatically terminate and the unpaid principal amount of all outstanding
Loans and all interest and other amounts as aforesaid shall automatically become
due and payable without further act of the Administrative Agent, any Issuing
Bank or any Bank.

     9.03 Rights Not Exclusive.  The rights provided for in this Agreement and
the other Loan Documents are cumulative and are not exclusive of any other

                                  Article X.

               THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT
               -------------------------------------------------

     10.01  Appointment of Agent.

     (a)  Each Bank hereby designates BT as Administrative Agent to act as
herein specified. Each Bank hereby irrevocably authorizes, and each holder of
any Note or participation in any Letter of Credit by the acceptance of a Note or
participation shall be deemed irrevocably to authorize, the Administrative Agent
to take such action on its behalf under the provisions of this Agreement and the
Notes and any other instruments and agreements referred to herein and to
exercise such powers and to perform such duties hereunder and thereunder as are
specifically delegated to or required of the Administrative Agent by the terms
of this Agreement and thereof and such other powers as are reasonably incidental
thereto. The Administrative Agent shall designate the Collateral Agent to hold
all Collateral and shall itself hold all payments of principal, interest, fees,
charges and expenses received pursuant to any Loan Document for the benefit of
itself and the Banks to be distributed as provided herein. The Administrative
Agent may perform any of its duties hereunder by or through its agents or
employees.

     (b)  The provisions of this Article X are solely for the benefit of the
Administrative Agent, the Collateral Agent and the Banks, and the Company shall
not have any rights as a third party beneficiary of any of the provisions of
this Article X (other than Section 10.09). In performing its functions and
duties under this Agreement, the Administrative Agent and the Collateral Agent
shall act solely as agent of the Banks and do not assume and shall not be deemed
to have assumed any obligation toward or relationship of agency or trust with or
for the Company or any of its Subsidiaries.

                                      90
<PAGE>

     10.02 Nature of Duties of Administrative Agent.  The Administrative Agent
shall have no duties or responsibilities except those expressly set forth in the
Loan Documents. Neither the Administrative Agent nor any of its officers,
directors, employees or agents shall be liable for any action taken or omitted
by it as such hereunder or in connection herewith, unless caused by its or their
gross negligence or willful misconduct. The duties of the Administrative Agent
shall be mechanical and administrative in nature; the Administrative Agent shall
not have by reason of the Loan Documents a fiduciary relationship in respect of
any Bank; and nothing in the Loan Documents, expressed or implied, is intended
to or shall be so construed as to impose upon the Administrative Agent any
obligations in respect of the Loan Documents except as expressly set forth
herein or therein.

     10.03 Lack of Reliance on Agent Related Persons.

     (a)  Independently and without reliance upon any Agent-Related Persons each
Bank, to the extent it deems appropriate, has made and shall continue to make
(i) its own independent investigation of the financial or other condition and
affairs of the Company and its Subsidiaries in connection with the taking or not
taking of any action in connection herewith and (ii) its own appraisal of the
creditworthiness of each of the Company and its Subsidiaries, and, except as
expressly provided in this Agreement, no Agent-Related Person shall have any
duty or responsibility, either initially or on a continuing basis, to provide
any Bank with any credit or other information with respect thereto, whether
coming into its possession before the making of the Loans or the issuance of any
Letter of Credit or at any time or times thereafter.

     (b)  No Agent-Related Person shall be responsible to any Bank for any
recitals, statements, information, representations or warranties herein or in
any document, certificate or other writing delivered in connection herewith or
for the execution, effectiveness, genuineness, validity, enforceability,
collectibility, priority or sufficiency of any Loan Document or the financial or
other condition of the Company or its Subsidiaries. No Agent-Related Person
shall be required to make any inquiry concerning either the performance or
observance of any of the terms, provisions or conditions of any Loan Document,
or the financial condition of the Company or any of its Subsidiaries, or the
existence or possible existence of any Default or Event of Default, unless
specifically requested to do so in writing by any Bank.

     (c)  For purposes of determining compliance with the conditions specified
in Section 5.01, each Bank shall be deemed to have consented to, approved or
accepted or to be satisfied with each document or other matter required
thereunder to be consented to or approved by or acceptable or satisfactory to
such Bank unless an officer of the Administrative Agent responsible for the
transactions contemplated by the Loan Documents shall have received written
notice from such Bank prior to the Effective Date specifying its objection
thereto and either such objection shall not have been withdrawn by written
notice to the Administrative Agent to that effect or such Bank shall not have
made available to the Administrative Agent the Bank's ratable portion of the
outstanding Loans.

     10.04 Certain Rights of the Administrative Agent.  The Administrative
Agent shall have the right to request instructions from the Majority Banks at
any time. If the Administrative Agent shall request instructions from the
Majority Banks or Banks, as applicable, with respect to any act or action
(including the failure to act) in connection with any Loan

                                      91
<PAGE>

Document, the Administrative Agent shall be entitled to refrain from such act or
taking such action unless and until the Administrative Agent shall have received
instructions from the Majority Banks, and the Administrative Agent shall not
incur liability to any Person by reason of so refraining. Without limiting the
foregoing, no Bank shall have any right of action whatsoever against the
Administrative Agent as a result of the Administrative Agent acting or
refraining from acting hereunder in accordance with the instructions of the
Majority Banks.

     10.05 Reliance by Administrative Agent.  The Administrative Agent shall
be entitled to rely, and shall be fully protected in relying, upon any note,
writing, resolution, notice, statement, certificate, telex, teletype or
telecopier message, cablegram, radiogram, order or other documentary,
teletransmission or telephone message believed by it to be genuine and correct
and to have been signed, sent or made by the proper person. The Administrative
Agent may consult with legal counsel (including counsel for the Company with
respect to matters concerning the Company), independent public accountants and
other experts selected by it and shall not be liable for any action taken or
omitted to be taken by it in good faith in accordance with the advice of such
counsel, accountants or experts.

     10.06 Indemnification of Agent-Related Persons.  To the extent any
Agent-Related Person is not reimbursed and indemnified by the Company, each Bank
will reimburse and indemnify such Agent-Related Person, in proportion to its
respective Commitment, for and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses
(including attorney costs) or disbursements of any kind or nature whatsoever
which may be imposed on, incurred by or asserted against such Agent-Related
Person in performing its duties hereunder, in any way relating to or arising out
of this Agreement, provided that no Bank shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the gross negligence or willful
misconduct of such Agent-Related Person.

     10.07 Administrative Agent in Individual Capacity.  With respect to its
obligation to lend under this Agreement, the Loans made by it and the Notes
issued to it, and its participation in Letters of Credit issued hereunder, BT
shall have the same rights and powers hereunder as any other Bank or holder of a
Note or participation interests and may exercise the same as though it was not
performing the duties specified herein; and the terms "Banks," "Majority Banks,"
"holders of Notes," or any similar terms shall, unless the context clearly
otherwise indicates, include the Administrative Agent in its individual
capacity. BT may accept deposits from, lend money to, acquire equity interests
in, and generally engage in any kind of banking, trust, financial advisory or
other business with the Company or any Affiliate of the Company as if it were
not performing the duties specified herein, and may accept fees and other
consideration from the Company for services in connection with the Loan
Documents and otherwise without having to account for the same to the Banks .

     10.08 Holders of Notes.  The Administrative Agent may deem and treat the
payee of any Note as the owner thereof for all purposes of the Loan Documents
unless and until a written notice of the assignment or transfer thereof shall
have been filed with the Administrative Agent. Any request, authority or consent
of any Person who, at the time of making such request or giving such authority
or consent, is the holder of any Note, shall be

                                      92
<PAGE>

conclusive and binding on any subsequent holder, transferee or assignee of such
Note or of any Note or Notes issued in exchange therefor.

10.09  Successor Administrative Agent.

     (a)  The Administrative Agent may, upon thirty (30) Business Days' notice
to the Banks and the Company, resign at any time (effective upon the appointment
of a successor Administrative Agent pursuant to the provisions of this Section
10.09) by giving written notice thereof to the Banks and the Company. Such
resignation of the Administrative Agent shall also operate as a resignation of
BT as an Issuing Bank (in respect of any Letters of Credit to be issued after
such resignation) and as Collateral Agent. Upon any such resignation, the
Majority Banks shall have the right, upon five (5) days' notice and approval by
the Company (which approval shall not be unreasonably withheld or delayed), to
appoint a successor Administrative Agent which shall also serve as a successor
Issuing Bank and successor Collateral Agent. If no successor Administrative
Agent (i) shall have been so appointed by the Majority Banks, and (ii) shall
have accepted such appointment, within thirty (30) days after the retiring
Administrative Agent's giving of notice of resignation then, upon five (5) days
notice, the retiring Administrative Agent may, on behalf of the Banks, appoint a
successor Administrative Agent, which shall also serve as a successor Issuing
Bank and successor Collateral Agent.

     (b)  Upon the acceptance of any appointment as 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 under
this Agreement. After any retiring Administrative Agent's resignation hereunder
as Administrative Agent, the provisions of this Article 10 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.

     (c)  In the event of a material breach by the Administrative Agent of its
duties hereunder, the Administrative Agent may be removed by the Majority Banks
(other than the Administrative Agent in its individual capacity and without
giving effect to any Loans or Commitments made by the Administrative Agent in
its individual capacity) for cause and the provisions of this Section 10.09
shall apply to the appointment of a successor Administrative Agent. Removal of
BT as Administrative Agent shall also operate as a removal of BT as an Issuing
Bank and Collateral Agent.

     10.10 Collateral Matters.

     (a)  Each Bank authorizes and directs the Collateral Agent to enter into
the Collateral Documents for the benefit of the Banks. Each Bank hereby agrees,
and each holder of any Note by the acceptance thereof will be deemed to agree,
that, except as otherwise set forth herein, any action taken by the Majority
Banks in accordance with the provisions of this Credit Agreement or the
Collateral Documents, and the exercise by the Majority Banks of the powers set
forth herein or therein, together with such other powers as are reasonably
incidental thereto, shall be authorized and binding upon all of the Banks. The
Administrative Agent and the Collateral Agent are hereby authorized on behalf of
all of the Banks, without the necessity of any

                                      93
<PAGE>

notice to or further consent from any Bank, from time to time prior to an Event
of Default, to take any action with respect to any Collateral or Collateral
Documents which may be necessary to perfect and maintain perfected the security
interest in and liens upon the Collateral granted pursuant to the Collateral
Documents.

     (b)  The Banks hereby authorize the Administrative Agent and the Collateral
Agent, at their option and in their discretion, to release any Lien granted to
or held by the Collateral Agent upon any Collateral (i) upon termination of the
Commitments and payment in full in cash and satisfaction of all of the
Obligations (other than those expressly stated to survive termination of this
Agreement, the repayment of the Loans and the termination of the Commitments) at
any time arising under or in respect of this Agreement or the Loan Documents or
the transactions contemplated hereby or thereby (including any required Cash
Collateralization), (ii) constituting property being sold or disposed of upon
receipt of the proceeds of such sale required (if applicable) to be delivered to
the Administrative Agent if the Company certifies to the Administrative Agent
that the sale or disposition is made in compliance with Section 8.02 (and the
Administrative Agent may rely conclusively on any such certificate, without
further inquiry), (iii) if approved, authorized or ratified in writing by the
Majority Banks, unless such release is required to be approved by all of the
Banks hereunder or (iv) constituting Cash, Cash Equivalents or Qualifying
Investments used for the purposes set forth in Section 8.01(u); provided that at
the time of such release no Default or Event of Default shall have occurred and
be continuing. Upon request by the Administrative Agent at any time, the Banks
will confirm in writing the Administrative Agent's and the Collateral Agent's
authority or to release particular types or items of Collateral pursuant to this
Section 10.10.

     (c)  Upon any sale and transfer of Collateral which is expressly permitted
pursuant to the terms of this Agreement, or consented to in writing by the
Majority Banks or all of the Banks, as applicable and upon at least five (5)
Business Days, prior written request by the Company, the Collateral Agent shall
(and is hereby irrevocably authorized by the Banks to) execute such documents as
may be necessary to evidence the release of the Liens granted to the Collateral
Agent for the benefit of the Administrative Agent and the Banks herein or
pursuant to this Agreement upon the Collateral that was sold or transferred;
provided that (i) the Collateral Agent shall not be required to execute any such
document on terms which, in the Collateral Agent's opinion, would expose the
Collateral Agent to liability or create any obligation or entail any consequence
other than the release of such Liens without recourse or warranty and (ii) such
release shall not in any manner discharge, affect or impair the Obligations or
any Liens upon (or obligations of the Company or any of its Restricted
Subsidiaries in respect of) all interests retained by the Company or any of its
Restricted Subsidiaries, including (without limitation) the proceeds of the
sale, all of which shall continue to constitute part of the Collateral. In the
event of any sale or transfer of collateral, or any foreclosure with respect to
any of the collateral, the Administrative Agent and the Collateral Agent shall
be authorized to deduct all of the expenses reasonably incurred from the
proceeds of any such sale, transfer or foreclosure.

     (d)  The Administrative Agent and the Collateral Agent shall have no
obligation whatsoever to the Banks or to any other Person to assure that the
Collateral exists or is owned by the Company or any of its Subsidiaries or is
cared for, protected or insured or that the Liens granted to the Collateral
Agent herein or pursuant to this Agreement have been properly or sufficiently or
lawfully created, perfected, protected or enforced or are entitled to any
particular

                                      94
<PAGE>

priority, or to exercise or to continue exercising at all or in any manner or
under any duty of care, disclosure or fidelity any of the rights, authorities
and powers granted or available to the Administrative Agent and the Collateral
Agent in this Section 10.10 or to the Collateral Agent in any of the Collateral
Documents, it being understood and agreed that in respect of the Collateral, or
any act, omission or event related thereto, the Administrative Agent and the
Collateral Agent may act in any manner they may deem appropriate in their sole
discretion, given the Administrative Agent's and the Collateral Agent's own
interest in the Collateral as one of the Banks and that the Administrative Agent
and the Collateral Agent shall have no duty or liability whatsoever to the
Banks, except for their gross negligence or willful misconduct; provided that
the Administrative Agent has prepared for the Company's execution financing
statements on form UCC-1 or UCC-3 in each jurisdiction in which the Company has
advised the Administrative Agent that it has Collateral and has arranged for
appropriate recordation thereof in each such jurisdiction.

    10.11     Actions with Respect to Default. In addition to the Administrative
Agent's right to take actions on its own accord as permitted under this
Agreement, the Administrative Agent shall take such action with respect to a
Default or Event of Default as shall be directed by the Majority Banks; provided
that until the Administrative Agent shall have received such directions, the
Administrative Agent shall (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable and in the best interests of the Banks.

    10.12     Delivery of Information.  The Administrative Agent shall not be
required to deliver to any Bank originals or copies of any documents,
instruments, notices, communications or other information received by the
Administrative Agent from the Company, Holdings, any of their respective
Subsidiaries, the Majority Banks, any Bank or any other Person under or in
connection with any Loan Document except (i) as specifically provided in any
Loan Document and (ii) as specifically requested from time to time in writing by
any Bank with respect to a specific document, instrument, notice or other
written communication received by and in the possession of the Administrative
Agent at the time of receipt of such request and then only in accordance with
such specific request.

    10.13     Liability of Agent-Related Persons. None of the Agent-Related
Persons shall (i) be liable for any action taken or omitted to be taken by any
of them under or in connection with any Loan Document or the transactions
contemplated thereby (except for its own gross negligence or willful
misconduct), or (ii) be responsible in any manner to any of the Banks for any
recital, statement, representation or warranty made by the Company or any of its
Subsidiaries or Affiliates, or any officer thereof, contained in any Loan
Document, or in any certificate, report, statement or other document referred to
or provided for in, or received by any Agent-Related Person under or in
connection with any Loan Document, or for the value of or title to any
Collateral, or the validity, effectiveness, genuineness, enforceability or
sufficiency of any Loan Document, or for any failure of the Company or any other
party to any Loan Document to perform its obligations hereunder or thereunder.
No Agent-Related Person shall be under any obligation to any Bank to ascertain
or to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, any Loan Document, or to inspect the properties,
books or records of the Company or any of the Company's Subsidiaries or
Affiliates.

Majority Banks or all the Banks, as the case may be, affect the rights or duties
of the applicable Issuing Bank under this Agreement or any L/C-Related Document
relating to any Letter of Credit Issued or to be Issued by it, (iii) no
amendment, waiver or consent shall, unless in writing and signed by the
Administrative Agent in addition to the Majority Banks or all the Banks, as the
case may be, affect the rights or duties of the Administrative Agent under any
Loan Document, (iv) the Fee Letters may be amended, or rights or privileges
thereunder waived, in a writing executed by the parties thereto and (v) no
amendment, waiver or consent shall, unless in writing and signed by the
Administrative Agent, the Syndication Agent, the Documentation Agent and Banks
holding at least 66 2/3% of the aggregate Commitments, have the effect of
otherwise increasing the Borrowing Base (other than any increase that is solely
the result of an action taken unilaterally by the Administrative Agent that
reverses a prior action unilaterally taken by the Administrative Agent (so long
as the taking of such first action was permitted under this Agreement) or an
action which is expressly permitted to be taken by the Administrative Agent or
the Agents unilaterally).  Notwithstanding the foregoing, amendments to the Loan
Documents entered into to give effect to any increase in the Commitments
pursuant to Section 2.11 need not be approved by the Majority Banks.

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

     11.03  No Waiver: Cumulative Remedies.  No failure to exercise and no delay
            ------------------------------
in exercising, on the part of the Administrative Agent, the Collateral Agent or
any Bank, any right, remedy, power or privilege hereunder, shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, remedy,
power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege.

     11.04  Indemnity.
            ---------
     (a)  Whether or not the transactions contemplated hereby are consummated,
the Company shall indemnify, defend and hold the Agent-Related Persons, each
Issuing Bank and each Bank and each of their respective officers, directors,
employees, counsel, agents and attorneys-in-fact (each, an "Indemnified Person")
harmless from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, charges, expenses and disbursements
(including fees and expenses of any law firm or external counsel) of any kind or
nature whatsoever which may at any time (including at any time following
repayment of the Loans, the termination of the Commitments and the Letters of
Credit and the termination, resignation or replacement of the Administrative
Agent or replacement of any Bank) be imposed on, incurred by or asserted against
any such Person in any way relating to or arising out of this Agreement or any
document contemplated by or referred to herein, or the transactions contemplated
hereby, or any action taken or omitted by any such Person under or in connection
with any of the foregoing, including with respect to any investigation,
litigation or proceeding (including any Insolvency Proceeding or appellate
proceeding) related to or arising out of any Loan Document or the Loans or
Letters of Credit or the use of the proceeds thereof, whether or not any
Indemnified Person is a party thereto (all the foregoing, collectively, the
"Indemnified Liabilities"); provided that the Company shall have no obligation
hereunder to any Indemnified Person with respect to Indemnified Liabilities
resulting primarily from the gross negligence or willful misconduct of such
Indemnified Person. The agreements in this Section shall survive payment of all
other Obligations.

     (b) (i) The Company shall indemnify, defend and hold harmless each
Indemnified Person, from and against any and all claims, liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses or disbursements (including

                                      98
<PAGE>

reasonable (giving due regard to prevailing circumstances) fees and expenses of
any law firm or external counsel and the allocated cost of internal
environmental audit or review services), which may be incurred by or asserted
against such Indemnified Person in connection with or arising out of any pending
or threatened investigation, litigation or proceeding, or any action taken by
any Person, with respect to any Environmental Claim arising out of or related to
any property subject to a mortgage in favor of the Collateral Agent or any Bank.
No action taken by legal counsel chosen by the Administrative Agent, the
Collateral Agent or any Bank in defending against any such investigation,
litigation or proceeding or requested remedial, removal or response action shall
vitiate or in any way impair the Company's obligation and duty hereunder to
indemnify and hold harmless the Administrative Agent, the Collateral Agent and
each Bank.

       (ii) In no event shall any site visit, observation, or testing by the
  Administrative Agent, the Collateral Agent or any Bank (or any contractee of
  the Administrative Agent, the Collateral Agent or any Bank) be deemed a
  representation or warranty by the Administrative Agent, the Collateral Agent
  or any Bank that Hazardous Materials are or are not present in, on, or under,
  the site, or that there has been or shall be compliance with any Environmental
  Law. Neither the Company nor any other Person is entitled to rely on any site
  visit, observation, or testing by the Administrative Agent, the Collateral
  Agent or any Bank. Neither the Administrative Agent, the Collateral Agent nor
  any Bank owes any duty of care to protect the Company or any other Person
  against, or to inform the Company or any other party of, any Hazardous
  Materials or any other adverse condition affecting any site or property.
  Neither the Administrative Agent, the Collateral Agent nor any Bank shall be
  obligated to disclose to the Company or any other Person any report or
  findings made as a result of, or in connection with, any site visit,
  observation, or testing by the Administrative Agent, the Collateral Agent or
  any Bank. The Company hereby acknowledges, represents and warrants that the
  Company and its Subsidiaries are solely responsible for the management and
  operation of the Facilities and that the financial covenants and capital
  expenditure covenants set forth herein have been set, by mutual agreement
  based upon financial information provided by the Company, at levels the
  Company has determined, based on information known to the Company at this
  time, will permit the expenditure of such amounts as are necessary to insure
  that the Facilities comply with applicable Environmental Laws at all times.
  Notwithstanding such covenants, but without in any way limiting the rights and
  remedies of the Banks hereunder, the Company and its Subsidiaries shall have
  the sole responsibility for ensuring that the Facilities comply with
  applicable Environmental Laws and shall remain obligated to make all
  expenditures necessary to ensure such compliance.

     (c)  Survival; Defense.  The obligations in this Section shall survive
          -----------------
payment of all other Obligations. At the election of any Indemnified Person, the
Company shall defend such Indemnified Person using legal counsel satisfactory to
such Indemnified Person in such Person's sole discretion, at the sole cost and
expense of the Company. All amounts owing under this Section shall be paid
within 30 days after demand.

     11.05  Marshaling; Payments Set Aside.  Neither the Administrative Agent,
            ------------------------------
the Collateral Agent, nor the Banks shall be under any obligation to marshal any
assets in favor of the Company or any other Person or against or in payment of
any or all of the Obligations. To the extent that the Company makes a payment to
the Administrative Agent or the Banks, or the

                                      99
<PAGE>

Administrative Agent or the Banks exercise their right of set-off, and such
payment or the proceeds of such set-off or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by the Administrative Agent
or such Bank in its discretion) to be repaid to a trustee, receiver or any other
party, in connection with any Insolvency Proceeding or otherwise, then (a) to
the extent of such recovery the obligation or part thereof originally intended
to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such set-off had not occurred, and (b) each
Bank severally agrees to pay to the Administrative Agent upon demand its pro
rata share of any amount so recovered from or repaid by the Administrative
Agent.

     11.06 Successors and Assigns.  The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties to this Agreement and their
respective successors and assigns subject to Section 11.07.

     11.07 Assignments, Participations, etc.

     (a)  Company Assignment.  The Company shall not assign this Agreement, or
any rights or obligations hereunder, without the prior written consent of the
Administrative Agent and the Banks; any assignment in violation of the foregoing
shall be void.

     (b)  Bank Assignments.  Each Bank may assign to one or more banks or other
financial institutions all or a portion of its rights and obligations under this
Agreement, the Notes and the other Loan Documents, with the consent of the
Administrative Agent, the Issuing Banks, and, so long as there is no Default or
Event of Default, the Company, which consent shall not be unreasonably withheld,
and upon execution and delivery to the Administrative Agent, for its acceptance
and recording in the Register (as defined below), of an agreement in
substantially the form of Exhibit H (an "Assignment and Assumption Agreement"),
together with surrender of any Note or Notes subject to such assignment and a
processing and recordation fee of $3,000 payable to the Administrative Agent for
its account. No such assignment shall be for less than $5,000,000 of the
combined Commitments unless it is to another Bank. (This Section does not apply
to branches and Affiliates of a Bank, it being understood that a Bank may make,
carry or transfer Loans at or for the account of any of its branch offices or
Affiliates without consent of the Administrative Agent.) Nothing in this Section
11.07 shall prevent or prohibit any Bank from pledging its rights under this
Agreement and/or its Loans, Notes and/or Letters of Credit hereunder to a
Federal Reserve Bank in support of borrowings made by such Bank from such
Federal Reserve Bank, provided that no such pledge shall at any time release
such Bank from any of its obligations under the Loan Documents.

     (c)  Agent's Register.  The Administrative Agent shall maintain a
register of the names and addresses of the Banks, their Commitments, and the
principal amount of their Loans (the "Register"). The Agent shall also maintain
a copy of each Assignment and Assumption Agreement delivered to and accepted by
it and modify the Register to give effect to each Assignment and Assumption
Agreement. Upon its receipt of each Assignment and Assumption Agreement and
surrender of the affected Note or Notes in accordance with Section 11.07(b), the
Agent will give prompt notice thereof to the Company and deliver to the Company
a copy of the Assignment and Assumption Agreement and the surrendered Note or
Notes.

                                      100
<PAGE>

Within five (5) Business Days after its receipt of such notice, the Company
shall execute and deliver to the Administrative Agent a new Note or Notes to the
order of the assignee in the amount of the Commitment or Commitments assumed by
it and to the assignor in the amount of the Commitment or Commitments retained
by it, if any. Such new Note or Notes shall re-evidence the Indebtedness
outstanding under the surrendered Note or Notes and shall be dated as of the
Effective Date. The Administrative Agent shall be entitled to rely upon the
Register exclusively for purposes of identifying the Banks hereunder.

     (d)  Bank Participations.  Each Bank may sell participations (without the
consent of the Administrative Agent, the Company or any other Bank) to one or
more parties in or to all or a portion of its rights and obligations under this
Agreement, the Notes and the other Loan Documents. Notwithstanding a Bank's sale
of a participation interest, its obligations hereunder shall remain unchanged.
The Company, the Agent, and the other Banks shall continue to deal solely and
directly with such Bank. No participant shall have rights to approve any
amendment or waiver of this Agreement except to the extent such amendment or
waiver would (i) increase the commitment of the Bank from whom the participant
purchased its participation interest, (ii) reduce the principal of, or rate or
amount of interest on the Loans subject to such participation, (iii) postpone
any date fixed for any payment of principal of, or interest on, the Loans
subject to the participation interest, and (iv) release all or a substantial
portion of the Collateral, other than, in each case, when otherwise permitted
hereunder.

     (e)  Disclosure of Information.  In connection with their efforts to
assign or sell participations pursuant to Sections 11.8(b) and (d), the
Administrative Agent or the Banks may disclose any information they have, now or
in the future, with respect to the business of the Company and its Subsidiaries
to prospective assignees or purchasers, provided that such prospective assignees
or purchasers agree in writing to be bound by the provisions of Section 11.08.

     11.08 Confidentiality.  Except as otherwise provided in this Section 11.08,
each Bank agrees that it will not disclose without the prior consent of the
Company, any information with respect to the Company or any of its Subsidiaries
which is furnished pursuant to this Agreement and which is designated by the
Company to the Banks in writing as confidential, provided, that any Bank may
disclose any such information (a) to its Affiliates, employees, auditors or
counsel, or to another Bank if the disclosing Bank or such disclosing Bank's
holding or parent company in its reasonable discretion determines that any such
party should have access to such information, provided that each such person
will be advised of the confidential nature of such information, (b) as has
become generally available to the public, (c) as may be required or appropriate
in any report, statement or testimony submitted to any Governmental Authority
having or claiming to have jurisdiction over such Bank, (d) as may be required
or appropriate in response to any summons or subpoena or in connection with any
litigation, and (e) in order to comply with any Requirement of Law.

     11.09 Set-off.  In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Company, any such notice being waived by the Company to the
full extent permitted by law, to set off and apply any and all deposits (general
or special, time or demand, provisional or final) at any time held by, and other

                                      101
<PAGE>

indebtedness at any time owing by, such Bank to or for the credit or the account
of the Company against any and all Obligations owing to such Bank, now or
hereafter existing, irrespective of whether or not the Administrative Agent or
such Bank shall have made demand under this Agreement or any Loan Document and
although such Obligations may be contingent or unmatured or fully secured.  Each
Bank agrees promptly to notify the Company and the Administrative Agent after
any such set-off and application made by such Bank; provided, however, that the
failure to give such notice shall not affect the validity of such set-off and
application.

     11.10  Notification of Addresses, Lending Offices, Etc.  Each Bank shall
notify the Administrative Agent in writing of any changes in the address to
which notices to the Bank should be directed, of addresses of any Lending
Office, of payment instructions in respect of all payments to be made to it
hereunder and of such other administrative information as the Administrative
Agent shall reasonably request.

     11.11  Counterparts.  This Agreement may be executed in any number of
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

     11.12  Severability.  The illegality or unenforceability of any provision
of this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

     11.13  No Third Parties Benefitted.  This Agreement is made and entered
into for the sole protection and legal benefit of the Company, the Banks, the
Administrative Agent and the Agent-Related Persons, and their permitted
successors and assigns, and no other Person shall be a direct or indirect legal
beneficiary of, or have any direct or indirect cause of action or claim in
connection with, this Agreement or any of the other Loan Documents.

     11.14  Governing Law and Jurisdiction.

     (a)  THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK; PROVIDED THAT THE
ADMINISTRATIVE AGENT AND THE BANKS SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL
LAW.

     (b)  ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO ANY LOAN DOCUMENT MAY
BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES FOR
THE SOUTHERN DISTRICT OF NEW YORK, AND BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, EACH OF THE COMPANY, THE ADMINISTRATIVE AGENT, THE ISSUING BANKS AND
THE BANKS CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-
EXCLUSIVE JURISDICTION OF THOSE COURTS. EACH OF THE COMPANY, THE ADMINISTRATIVE
AGENT, THE ISSUING BANKS AND THE BANKS IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM
NON CONVENIENS, WHICH IT

                                      102
<PAGE>

MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH
JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED TO THIS
AGREEMENT. THE COMPANY, THE ADMINISTRATIVE AGENT, THE ISSUING BANKS AND THE
BANKS EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS,
WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY NEW YORK LAW.

     11.15  Waiver of Jury Trial.  THE COMPANY, THE ISSUING BANKS, THE BANKS AND
THE ADMINISTRATIVE AGENT EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY
OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THE
LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY
ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES
AGAINST ANY OTHER PARTY OR ANY AGENT-RELATED PERSON, PARTICIPANT OR ASSIGNEE,
WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE.  THE
COMPANY, THE BANKS, THE ISSUING BANKS AND THE ADMINISTRATIVE AGENT EACH AGREE
THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A
JURY.  WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR
RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO
ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART,
TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THE LOAN DOCUMENTS OR ANY
PROVISION THEREOF.  THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THE LOAN DOCUMENTS.

     11.16  Entire Agreement.  This Agreement, together with the other Loan
Documents, embodies the entire agreement and understanding among the Company,
the Banks and the Administrative Agent, and supersedes all prior or
contemporaneous agreements and understandings of such Persons (other than that
certain Commitment Letter, dated as of September 27, 1999, among the Company and
the Agents), verbal or written, relating to the subject matter of this Agreement
and thereof.

2  If Total Debt/LTM EBITDA Less than 4.0, each rate in this Pricing Grid will
   be reduced by 25 basis points. Pricing on the Indebtedness/LTM EBITDA option
   will be determined (a) using, as the numerator, Indebtedness that would
   appear as a line item on a consolidated balance sheet of the Company and its
   Restricted Subsidiaries as of the last day of the relevant month and (b)
   using, as the denominator ("LTM EBITDA"), EBITDA of the Company and its
   Restricted Subsidiaries for the consecutive 12-month period ending on such
   last day.

4  Pricing on the Average Cash as percentage of Average Outstandings will be
   determined (a) using, as the numerator, the average daily amount of Cash
   Collateral during the relevant month and (b) using, as the denominator (i.e.,
   "Outstandings"), the sum of (i) the daily average undrawn stated amount of
   all Letters of Credit outstanding during such month and (ii) the daily
   average of all Loans outstanding during such month, with such fraction being
   calculated as a percentage. Cash Collateral means, the sum, without
   duplication, of Eligible Cash, Eligible Cash Equivalents and 95% of Eligible
   Investments (in each case as reflected in the books and records of the
   Administrative Agent on such date of determination).

5  "Average Utilization" on any day means a fraction (a) the numerator of which
   is the Effective Amount of all L/C Obligations under clauses (i), (iii) and
   (iv) of the definition thereof plus the Effective Amount of all Loans on such
   day and (b) the denominator of which is the aggregate Commitments on such
   day, expressed as a percentage.<PAGE>

     5.   ADMINISTRATION.

     The Plan shall be administered by the Board, which shall have full and
exclusive power to interpret the Plan, to grant waivers of Award restrictions
and to adopt such rules, regulations and guidelines for carrying out the Plan as
it may deem necessary or proper, all of which powers shall be executed in the
best interest of the Company and in keeping with the objectives of the Plan.
These powers include, but are not limited to, the adoption of modifications,
amendments, procedures, subplans and the like as are necessary to comply with
provisions of the laws and regulations of the jurisdictions in which the Company
operates in order to assure the viability of Awards granted under the Plan and
to enable Participants regardless of where employed to receive advantages and

     The Board may delegate to the Committee or to the Chief Executive Officer

such conditions or limitations as the Board may establish, except (a) that only
the Board or the Committee may select, and grant Awards to, Participants who are
subject to Section 16 of the 1934 Act and (b) to the extent that the grant or
exercise of such authority would cause any Award or transaction to fail to
qualify for exemption under Rule 16b-3.

     7.   AWARDS.

     The Board shall determine who may participate in the Plan and the number
and type of Awards to be made to each Participant and shall set forth in the
related Award Agreement or other appropriate manner the terms, conditions,
requirements and limitations applicable to each Award.  Awards may be granted
singly or in combination.  Awards may also be made in combination or in tandem
with, in replacement of, or as alternatives to, grants or rights under any other
employee plan of the Company, including the plan of any acquired entity.  The
Board may make the following type of Awards: stock options; i.e., rights to
purchase a specified number of shares of Capital Stock the purchase price of
which shall be determined by the Board.  No Stock Option shall be exercisable
more than ten years after the date of its grant.

     No Award shall confer on any Participant any of the rights of a shareholder
of the Company unless and until shares of Capital Stock are duly issued or
transferred to the Participant in accordance with the terms of the Award.

     No Participant, officer, employee or director shall have any claim to be
granted any Award under the Plan, and there is no obligation for uniformity of
treatment of Participants or any other persons.  Nothing contained in the Plan
or any Award Agreement shall confer, and no grant of an Award shall be construed
as conferring, upon any employee any right to continue in the employ of the
Company or to interfere in any way with the right of the Company to terminate
the employee's employment at any time or increase or decrease the employee's
compensation from the rate in existence at the time of granting of an Award.

     The maximum number of shares of Capital Stock with respect to which Stock
Options may be granted to any one Participant under the Plan during any calendar
year is 1,000,000 shares.

     The Board may, at or prior to the time of grant, designate any Award as a
Qualified Performance-Based Award, in which event it shall take such action with
respect to such Award and the terms thereof (including the imposition of
additional requirements not otherwise required by the terms of the Plan), and
the provisions of the Plan or any Award Agreement shall be construed or deemed
amended, as shall be necessary to cause such Award to qualify for the Section
162(m) Exemption.

set forth in or pursuant to the related Award Agreement including, without
limitation, registration rights, tag-along rights, drag-along rights and

     The Company shall have the right to deduct applicable taxes from any Award
payment and withhold, at the time of delivery or vesting of shares under the
Plan, an appropriate number of shares for payment of taxes required by law, to
require a Participant to pay to the Company in cash any amounts required to be
withheld or to take such other action as may be necessary in the opinion of the
Company to satisfy all obligations for withholding of such taxes.

     11.  CHANGES TO THE PLAN AND AWARDS.

     (a)  Changes to the Plan.  The Board may amend, alter, suspend, discontinue
or terminate the Plan without the consent of shareholders or Participants,
except as is required by any federal or state law or regulation or the rules of
any stock exchange on which the Capital Stock may be listed, or if the Board in
its discretion determines that obtaining such shareholder approval is for any
reason advisable; provided, however, that, without the consent of an affected
Participant, no amendment, alteration, suspension, discontinuation or
termination of the Plan may impair the rights of such Participant under any
Award theretofore granted to such Participant.

     (b)  Changes to Awards. The Board may waive any conditions or rights under,
or amend, alter, accelerate, suspend, discontinue or terminate, any Award
theretofore granted and any Award Agreement relating thereto; provided, however,
that, without the consent of an affected Participant, no such amendment,
alteration, suspension, discontinuation or termination of any Award may impair
the rights of such Participant under such Award.

     12.  TERMINATION OF EMPLOYMENT.

     If the employment of a Participant by the Company terminates, all Awards
and other benefits under the Plan (including Stock Option Shares) held by such
Participant shall be governed by, and shall be subject to, the terms and
conditions set forth below.

     (a)  Death or Disability.

          (i)  If the employment of any Participant is terminated as a result of
death or Disability, all Stock Options held by such Participant (A) which are
not then exercisable shall terminate and (B) which are then exercisable shall
terminate at the close of business in St. Louis, Missouri on the date which is
the first anniversary of such Participant's termination of employment.  In
addition, the Company shall have the right to purchase (A) from time to time so
long as they are exercisable, all or any portion of such exercisable Stock
Options at a price equal to the Net Stock Option Value of the shares of Capital
Stock subject to such Stock Options on the purchase date and (B) any or all of
the Stock Option Shares held by such Participant at a price per share equal to
their Fair Market Value.

                                      -4-
<PAGE>

          (ii)   In the event of a Participant's death, any remaining rights
with respect to any outstanding Award shall be exercised by the Participant's
estate or beneficiaries under such terms as may be specified in the applicable
Award Agreement. Any such remaining rights to outstanding Awards shall pass by
will or the laws of descent and distribution in the following order: (A) to
beneficiaries so designated by the Participant; if none, then (B) to a legal
representative of the Participant; if none, then (C) to the persons entitled
thereto as determined by a court of competent jurisdiction. Subject to
subparagraph (iv) below, Awards so passing shall be exercised or paid out at
such times and in such manner as if the Participant were living.

          (iii)  In the event a Participant is deemed by the Company to be
Disabled, Awards and rights to any such Awards which are payable or exercisable
may be paid to or exercised by the Participant, if legally competent, or a
conservator or other legally designated agent or representative if the
Participant is legally incompetent by virtue of such Disability.

          (iv)   After the death or Disability of a Participant, the Board may
in its sole discretion at any time (A) terminate restrictions in Award
Agreements, (B) accelerate any or all installments and rights, and (C) instruct
the Company to pay the total of any accelerated payments in a lump sum to the
Participant, the Participant's estate, beneficiaries or representative -
notwithstanding that, in the absence of such termination of restrictions or
acceleration of payments, any or all of the payments due under the Awards might
ultimately have become payable to other beneficiaries.

     (b)  Cause.

          (i)    If the employment of any Participant is terminated for Cause,
all Stock Options held by such Participant shall terminate. In addition, the
Company shall have the right to purchase, from time to time for a period of 30
days following such termination, any or all of the Stock Option Shares held by
such Participant at a price per share equal to the lower of its cost (the
exercise price) or its Fair Market Value. For purposes of the foregoing, "Cause"
shall have the same meaning as in the Participant's written employment agreement
with the Company or, if the Participant has not entered into a written
employment agreement, shall mean (A) gross neglect of or wilful and continuing
refusal to substantially perform the Participant's duties (other than due to
death or Disability), (B) breach of any material policy of the Company
(including, without limitation, any policy regarding confidentiality), (C)
willfully engaging in conduct which is demonstrably injurious to Blackstone or
the Company, or (D) commission of or the entering of a plea of guilty or nolo
contendere to (1) a felony or (2) a misdemeanor involving moral turpitude.

          (ii)   Termination of a Participant for Cause shall be effected by a
majority vote of the Board at a meeting at which such Participant (and such
Participant's counsel) shall have had the opportunity to be heard, provided that
such Participant shall have received written notice of such termination at least
30 days prior to such meeting and such Participant shall have failed to cure
such Cause (if curable) within 15 days of such notice to the reasonable
satisfaction of the Board.

The foregoing provisions of this subsection (b) are applicable solely for
purposes of the Plan and shall not affect in any way the right of the Company to
terminate any employee or (except regarding the Plan) the consequences thereof.

                                      -5-
<PAGE>

     (c)  Other Termination.

          (i)  If the employment of any Participant is terminated for any reason
other than death or Disability or Cause, as described in subsections (a) and (b)
above, all Stock Options held by such Participant (A) which are not then
exercisable shall terminate and (B) which are then exercisable shall terminate
at the close of business in St. Louis, Missouri on the date which is 90 days
after such Participant's termination of employment.  In addition, the Company
shall have the right to purchase (A) from time to time so long as they are
exercisable, all or any portion of such exercisable Stock Options at a price
equal to the Net Stock Option Value of the shares subject to such Stock Options
on the purchase date and (B) any or all of the Stock Option Shares held by such
Participant at a price per share equal to their Fair Market Value.

          The right of the Company to purchase exercisable Stock Options and
Stock Option Shares pursuant to this Section 12 shall be exercisable upon 30
days written notice to the Participant specifying the purchase date.

          Any provision of the Plan to the contrary notwithstanding, the Company
shall not have the right to purchase any exercisable Stock Options or Stock
Option Shares pursuant to this Section 12 following the establishment (in the
reasonable judgment of the Board) of a public market for the Capital Stock.

          In the event of uncertainty as to interpretation of or controversies
concerning this Section 12, the Board's determinations shall be binding and
conclusive.

     13.  CANCELLATION AND RESCISSION OF AWARDS.

     Unless the Award Agreement specifies otherwise, the Board may cancel any
unexpired, unpaid or deferred Awards at any time if the Participant is not in
compliance with all other applicable provisions of the Award Agreement, the Plan
and with the following conditions:

     (a)  A Participant shall not render services for any organization or engage
directly or indirectly in any business which, in the judgment of the Chief
Executive Officer of the Company or other senior officer designated by the
Board, is or becomes competitive with the Company, or which organization or
business, or the rendering of services to such organization or business, is or
becomes otherwise prejudicial to or in conflict with the interests of the
Company.  For a Participant whose employment has terminated, the judgment of the
Chief Executive Officer shall be based on the Participant's position and
responsibilities while employed by the Company, the Participant's post-
employment responsibilities and position with the other organization or
business, the extent of past, current and potential competition or conflict
between the Company and the other organization or business, the effect on the
Company's customers, suppliers and competitors of the Participant's assuming the
post-employment position, and such other considerations as are deemed relevant
given the applicable facts and circumstances.  A Participant who has retired
shall be free, however, to purchase, as an investment or otherwise, stock or
other securities of such organization or business so long as they are listed
upon a recognized securities exchange or traded over-the-counter, and such
investment does not represent a substantial investment to the Participant or a
greater than 5% equity interest in the organization or business.

     (b)  A Participant shall not, without prior written authorization from the
Company, disclose to anyone outside the Company, or use in other than the
Company's business, any confidential information or material relating to the
business of the Company, acquired by the Participant either during or after
employment with the Company.

                                      -6-
<PAGE>

     (c)  Failure to comply with the provisions of paragraph (a) or (b) of this
Section 13 prior to or during the six months after any exercise, payment or
delivery pursuant to an Award shall cause such exercise, payment or delivery to
be rescinded.  The Company shall notify the Participant in writing of any such
rescission within two years after such exercise, payment or delivery.  Within
ten days after receiving such a notice from the Company, the Participant shall
pay to the Company the amount of any gain realized or payment received as a
result of the rescinded exercise, payment or delivery pursuant to an Award.
Such payment shall be made either in cash or by returning to the Company the
number of shares of Capital Stock that the Participant received in connection
with the rescinded exercise, payment or delivery.

     14.  NONASSIGNABILITY.

          Unless otherwise provided by the Board, no Award or any other benefit
under the Plan (including Stock Option Shares) shall be assignable or
transferable, or payable to or exercisable by anyone other than the Participant
to whom it was granted , except (a) pursuant to subparagraph (a) of Section 12
and (b) that Stock Option Shares shall be assignable and transferrable subject
to such limitations and conditions as may be set forth in a stockholder or
similar agreement entered into in connection therewith.

     15.  MERGERS, REORGANIZATIONS AND OTHER CORPORATE TRANSACTIONS; CHANGE IN
          CONTROL.

     (a)  General.  In the event of any change in the outstanding Capital Stock
by reason of any stock dividend or split, reorganization, recapitalization,
merger, consolidation, spin-off, combination or exchange of Capital Stock or
other corporate exchange, or any distribution to shareholders of Capital Stock
other than regular cash dividends, the Board in its sole discretion and without
liability to any person may make such substitutions or adjustments, if any, as
it deems to be equitable, as to (i) the number or kind of Capital Stock or other
securities issued or reserved for issuance pursuant to the Plan or pursuant to
outstanding Awards, (ii) the Stock Option price and/or (iii) any other affected
terms of such Awards.

     (b)  Change in Control.  Except as may otherwise be provided in the related
Award Agreement, in the event of a Change in Control, the Board in its sole
discretion and without liability to any person may take such actions, if any, as
it deems necessary or desirable with respect to any Award (including, without
limitation, (i) the acceleration of an Award, (ii) the payment of a cash amount
in exchange for the cancellation of an Award and/or (iii) the requiring of the
issuance of substitute Awards that will substantially preserve the value, rights
and benefits of any affected Awards previously granted under the Plan) as of the
date of the consummation of the Change in Control.

     (c)  Pooling of Interest Accounting.  Notwithstanding the foregoing, in the
event that the implementation of any provision of the Plan would cause a Change
in Control transaction that was intended to be eligible for pooling-of-interests
accounting not to be so eligible, the Board may take any steps that it deems
necessary to preserve pooling treatment.

     16.  NOTICE.

     Any notice to the Company required by any of the provisions of the Plan
shall be addressed to the Legal Department of Clark Holdings in writing, and
shall become effective when it is received.

     17.  LEGAL REQUIREMENTS.

     (a)  General.  The Plan, the granting and exercising of Awards thereunder
and the other obligations of the Company under the Plan shall be subject to all
applicable federal and state laws, rules and regulations and to such approvals
by any regulatory or governmental agency as may be required.  The Company, in
its discretion, may postpone the granting and exercising of Awards, the issuance
or delivery of Capital Stock under any Award or any other action permitted under
the Plan to permit the Company, with reasonable diligence, to complete such
stock exchange listing or registration or qualification of such Capital Stock or
other required action under any federal or state law, rule or regulation and may
require any Participant to make such representations and furnish such
information as it may consider appropriate in connection with the issuance or
delivery of Capital Stock in compliance with applicable laws, rules and
regulations.  The Company shall not be obligated by virtue of any provision of
the Plan to recognize the exercise of any Award or to otherwise sell or issue
Capital Stock in violation of any such laws, rules, or regulations; and any
postponement of the exercise or settlement of any Award under this provision
shall not extend the term of such Award, and neither the Company nor its
directors or officers shall have any obligation or liability to the Participant
with respect to any Award (or stock issuable thereunder) that shall lapse
because of such postponement.

     (b)  Rule 16b-3.  It is the intent of the Company that any Award granted to
a person who is subject to Section 16 of the 1934 Act qualify for exemption
under Rule 16b-3.  Accordingly (i) if any provision of the Plan or any Award
Agreement would cause such an Award to fail to qualify for such exemption, such
provision shall be construed or deemed amended to the extent necessary to enable
such Award to qualify for such exemption, and (ii) any provision of the Plan
which is intended solely to cause an Award to qualify for exemption under Rule
16b-3 shall apply only to the extent that such Award would otherwise be subject
to such Rule.

     18.  GOVERNING LAW.

     The Plan and all determinations made and actions taken pursuant thereto, to
the extent not otherwise governed by the laws of the United States, shall be
governed by the laws of the State of Delaware and construed accordingly.

Plan shall not become effective and no initial Awards shall be effective unless
and until Clark Holdings obtains the affirmative vote of more than seventy-five
percent of all shareholders who (a) are not receiving any initial Awards or (b)
are not lineally related to, or the spouse of, any individual who would receive
the initial Awards.  The Board shall have the authority to grant Awards prior to
such approval; provided that the effectiveness of such Awards shall be subject
to such shareholder approval of the Plan.  The Plan shall terminate ten years
after its effective date, subject to earlier termination by the Board pursuant
to Section 11, after which no Awards may be made under the Plan, but any such
termination shall not affect Awards then outstanding or the authority of the
Board to continue to administer the Plan.

except for any transfer, sale, assignment, exchange, mortgage, pledge,
hypothecation or other disposition of any Shares or any interest therein
"Transfer") effected pursuant to an effective registration statement filed under
 --------
the Securities Act, no Transfer shall occur unless the Company has been
furnished with an opinion in form and substance reasonably satisfactory to the
Company of counsel reasonably satisfactory to the Company that such Transfer is
exempt from the provisions of Section 5 under the Securities Act.

          (b)    Holder hereby agrees that, except for Transfers in connection
with a sale of shares of Common Stock to the public pursuant to an effective
registration statement filed under the Securities Act ("Public Offering"),
                                                        ---------------
Transfers pursuant to Rule 144 (other than Rule 144(k)) under the Securities Act

its transferor by the terms of, Articles II and III of this Agreement.

          (c)    Notwithstanding anything contained herein to the contrary, but
subject to Section 2.2, Holder hereby agrees that, in addition to the limitation
on transfer set forth in Section 2.8(a), no Transfer shall occur until eighteen
months after the date of Clark's initial underwritten Public Offering or such
earlier date after such initial Public Offering on which an underwritten
registered secondary offering involving shares of Common Stock occurs.
Notwithstanding the foregoing, in the event Blackstone sells shares for its own
account in such initial Public Offering, Holder may transfer Shares in such
offering in accordance with Section 2.7 hereof, except that in such circumstance
clause (ii) of Section 2.7(b) shall be deemed to read as follows: (ii) second,
to the extent that the number of shares of Common Stock which are proposed to be
sold in such offering is less than the number of shares of Common Stock which
the Company has been advised can be sold in such offering without having the
adverse effect referred to above, the number of shares of Common Stock
Blackstone intends to dispose of in such offering shall have priority.

          II.2   Transfers to Affiliates.  Notwithstanding anything contained
                 -----------------------
herein to the contrary, Holder shall be entitled from time to time to Transfer
any or all of the Shares beneficially owned by Holder to Holder's spouse or
descendants, or to a trust in favor of Holder's spouse or descendants, or to any
other entity the owners of which consist exclusively of Holder, Holder's spouse,
Holder's descendants or such trusts ("Permitted Affiliate"), who, in each such
                                      -------------------
case, agree in a writing satisfactory in form and substance to the Company to
become a party to, and be bound to the same extent as its transferor by the
terms of, Articles II and III of this Agreement.

          II.3   Effect of Void Transfers.  In the event of any purported
                 ------------------------
Transfer of any shares of Common Stock in violation of the provisions of this
Agreement, such purported Transfer shall be void and of no effect and the
Company shall not give effect to such Transfer.

                 --------------------
Common Stock issued to Holder shall bear the following legend on the face

                          --------
right to sell shares of Common Stock to the proposed transferee pursuant to this
Section 2.5, the Tagging Stockholder must agree to make to the transferee the
same representations, warranties, covenants, indemnities and agreements that the
Transferring Stockholder agrees to make in connection with the proposed Transfer
of the shares of Common Stock of the Transferring Stockholder; and provided
                                                                   --------

          II.6  Drag-Along Rights.  So long as this Agreement shall remain in
                -----------------
effect and Blackstone beneficially owns on a fully diluted basis an aggregate
number of shares of Common Stock not less than one-fourth (1/4) of the Common
Stock owned by Blackstone on the date hereof, if Blackstone receives an offer
from a person other than Holder or any of its affiliates (a "Third Party") to
                                                             -----------
purchase 25% or more  of the shares of Common Stock owned by Blackstone and such
offer is accepted by Blackstone, then Holder hereby agrees that it will Transfer
the Applicable Number  (as defined below) of Shares owned by it to such Third
Party upon the terms and conditions of the offer (including without limitation
time of payment and form of consideration) applicable to Blackstone, provided
                                                                     --------
that Holder must agree to make to the Third Party the same representations,
warranties, covenants, indemnities and agreements that Blackstone agrees to make
in connection with the proposed Transfer; and provided further, that all
                                              -------- -------
representations and warranties shall be made by Holder and Blackstone severally
and not jointly and that the liability of Holder and Blackstone (whether
pursuant to a representation, warranty, covenant, indemnification provision or
agreement) for liabilities in respect of the Company shall be evidenced in
writings executed by them and the Third Party and shall be borne by each of them
on a pro rata basis.  The "Applicable Number" shall mean a number (rounded up to
the nearest whole number) equal to the product of (i) the quotient determined by
dividing (A) the aggregate number of shares owned by Blackstone to be included
in the contemplated Transfer by (B) the aggregate number of shares owned by
Blackstone immediately prior to the contemplated Transfer, and (ii) the total
number of shares owned by Holder.

          II.7  Piggyback Rights.  (a)  Each time the Company is planning to
                ----------------
file a registration statement under the Securities Act in connection with the
proposed offer and sale of Common Stock by the Company and/or Blackstone (other
than under Form S-8 or Form S-4 or a similar successor form), the Company will
give prompt written notice thereof to Holder regarding Holder's rights under
this Section 2.7, at least 15 business days prior to the anticipated filing date
of such registration statement; provided, that Holder and its affiliates shall
                                --------
have no rights pursuant to this Section 2.7 with respect to the first Public
Offering of Common Stock if the Company is the only person including shares of
Common Stock in such registration statement.  Upon the written request of Holder
or the Permitted Affiliates made within 5 business days after the receipt of any
such notice from the Company, which request shall specify the number of Shares
(the "Holder Piggy-Back Shares") intended to be disposed of by Holder or the
      ------------------------
Permitted Affiliates in such offering, the Company will use its reasonable
efforts to effect the registration under the Securities Act of all Holder Piggy-
Back Shares which the Company has been so requested to register by Holder, to
the extent required to permit the disposition of the Holder Piggy-Back Shares to
be registered; provided, that (i) if, at any time after giving written notice of
               --------
its intention to register any Common Stock and prior to the effective date of
the registration statement filed in connection with such registration, the
Company or Blackstone shall determine for any reason not to proceed with the
proposed registration, the Company may at its election give written notice of
such determination to the holder of Holder Piggy-Back Shares and thereupon shall
be relieved of its obligation to register any Holder Piggy-Back Shares in
connection with such registration and (ii) if such registration involves an
underwritten offering, the holder of Holder Piggy-Back Shares requesting to be
included in the registration must sell its shares to the underwriters on the
same terms and conditions as apply to the Company and/or Blackstone.

          (b)   If a registration pursuant to this Section 2.7 involves an
underwritten offering and the managing underwriter or underwriters in good faith
advise the Company in writing that, in their opinion, the number of shares of
Common Stock which the Company, Blackstone and the holder of Holder Piggy-Back
Shares intend to include in such registration exceeds the number of shares of
Common Stock which can be sold in such offering without having an adverse effect
on such offering (including the price at which the shares of Common Stock can be
sold), then the Company will include in such registration (i) first, 100% of the
shares the Company proposes to sell for its own account, if any, and 100% of the
shares of

                                                                              21

any person exercising demand registration rights (other than Blackstone), if
any, and (ii) second, to the extent that the number of shares described under
clause (i) is less than the number of shares of Common Stock which the Company
has been advised can be sold in such offering without having the adverse effect
referred to above, the number of shares Blackstone intends to dispose of in such
offering, the Holder Piggy-Back Shares and shares of any other person exercising
similar piggy-back registration rights, on a pro rata basis.

          II.8  Other Registration-Related Matters.
                ----------------------------------

          (a)   Holder agrees that it shall not effect any direct or indirect
Transfer of Com mon Stock during the 14 days prior to or the 180 day period
beginning on the effective date of a registration statement (whether pursuant to
Section 2.7 or otherwise, except as part of such registration) if and to the
extent reasonably requested in writing by the managing underwriter of the
underwritten public offering.

          (b)   The Company agrees not to effect any direct or indirect Transfer
of Common Stock during the 14 days prior to and the 180 day period beginning on

offering of Common Stock, if and to the extent reasonably requested in writing
by the managing underwriter of the underwritten public offering.

          (c)   The Company may require any person that is selling shares of
Common Stock in a Public Offering to furnish to the Company such information
regarding such person and the distribution of the shares of Common Stock which
are included in a Public Offering as may from time to time reasonably be
requested in writing in order to comply with the Securities Act.

     below), a price per share equal to the lower of (x) the price per share
     paid by Holder (as proportionately adjusted for all subsequent stock
     splits, stock dividends and other recapitalizations) and (y) Fair Market
     Value (as defined below); or

          (ii)  if Holder's employment was terminated for any other reason, Fair

such shares as of any date shall be the closing date sale price on that date of
a share of Common Stock as reported in the NASDAQ National Market Issues
quotations of the Midwest Edition of the Wall Street Journal, or (b) if the
Common Stock is traded on the New York Stock Exchange, the Fair Market Value of
