accordance with procedures customary in the relevant market. The Collateral
Agent will calculate from time to time the net amount of the "mark-to-market"
values of all Specified Hedge Agreements on the basis of such counterparty
report, and if such net amount is unfavorable to the Borrower (i.e., the
Borrower would owe a net amount under all Specified Hedge Agreements if all
Specified Hedge Agreements were terminated on such date), the Collateral Agent
will establish a Reserve in an amount equal to such net unfavorable amount, and
will maintain such Reserve until the next determination by the Collateral Agent
pursuant to this paragraph.

                  2.7      Repayment of Loans; Evidence of Debt. (a) The
Borrower hereby unconditionally promises to pay to the Administrative Agent for
the account of the appropriate Revolving Credit Lender or Term Loan Lender, as
the case may be, (i) the then unpaid principal

<PAGE>
                                                                              28

amount of each Revolving Credit Loan of such Revolving Credit Lender on the
Revolving Credit Termination Date (or on such earlier date on which the Loans
become due and payable pursuant to Section 8), and (ii) the principal amount of
each Term Loan of such Term Loan Lender in installments according to the
amortization schedule set forth in Section 2.3 (or on such earlier date on which
the Loans become due and payable pursuant to Section 8). The Borrower hereby
further agrees to pay interest on the unpaid principal amount of the Loans from
time to time outstanding from the date hereof until payment in full thereof at
the rates per annum, and on the dates, set forth in Section 2.14. The Borrower
agrees that, if a Dominion Event shall have occurred (unless a Dominion
Termination Event has occurred subsequently and is continuing), the Collateral
Agent may (and the Collateral Agent hereby agrees that it shall) (i) cause each
bank that maintains any account subject to a Control Agreement or a Lockbox
Agreement to transfer, on a daily basis, all collected funds in any such account
to a Concentration Account and (ii) apply any amounts on deposit in a
Concentration Account to repay Revolving Credit Loans whenever any Revolving
Credit Loans are outstanding.

                  (b) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of the Borrower to such
Lender resulting from each Loan of such Lender from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Agreement.

                  (c) The Administrative Agent, on behalf of the Borrower, shall
maintain the Register pursuant to Section 10.6(d), and a subaccount therein for
each Lender, in which shall be recorded (i) the amount of each Loan made
hereunder and any Note evidencing such Loan, the Type of such Loan and each
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) both the amount of any sum received by the Administrative
Agent hereunder from the Borrower and each Lender's share thereof.

                  (d) The entries made in the Register and the accounts of each
Lender maintained pursuant to Section 2.7(b) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrower therein recorded; provided, however, that the
failure of any Lender or the Administrative Agent to maintain the Register or
any such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans made to
the Borrower by such Lender in accordance with the terms of this Agreement.

                  (e) The Borrower agrees that, upon the request to the
Administrative Agent by any Lender, the Borrower will promptly execute and
deliver to such Lender a promissory note of the Borrower evidencing any Term
Loans or Revolving Credit Loans, as the case may be, of such Lender,
substantially in the forms of Exhibit G-1 or G-2, respectively (a "Term Note" or
"Revolving Credit Note", respectively), with appropriate insertions as to date
and principal amount; provided, that delivery of Notes shall not be a condition
precedent to the occurrence of the Closing Date or the making of the Loans on
the Closing Date.

                  2.8      Commitment Fees, etc. (a) The Borrower agrees to pay
to the Administrative Agent (i) for the account of each Revolving Credit Lender,
a commitment fee for the period from and including the Closing Date to the last
day of the Revolving Credit

<PAGE>
                                                                              29

Commitment Period, computed at the Commitment Fee Rate on the average daily
amount of the Available Revolving Credit Commitment of such Lender during the
period for which payment is made, and (ii) for the account of each Term Loan
Lender, a commitment fee for the period from and including the Closing Date to
the earlier of (A) the Delayed Draw Borrowing Date and (B) the last day of the
Delayed Draw Commitment, computed at the Commitment Fee Rate on the average
daily amount of the Available Term Loan Commitment of such Lender during the
period for which payment is made, in each case payable quarterly in arrears on
the last day of each March, June, September and December and on the Revolving
Credit Termination Date (in the case of the Revolving Credit Commitments) or the
earlier of (x) the Delayed Draw Borrowing Date and (y) the last day of the
Delayed Draw Commitment Period (in the case of the Term Loan Commitments),
commencing on the first of such dates to occur after the date hereof.

                  (b) The Borrower agrees to pay to the Collateral Agent the
fees in the amounts and on the dates previously agreed to in writing by the
Borrower and the Collateral Agent.

                  (c) The Borrower agrees to pay to the Administrative Agent the
fees in the amounts and on the dates from time to time agreed to in writing by
the Borrower and the Administrative Agent.

                  2.9      Termination or Reduction of Credit Commitments. (a)
The Borrower shall have the right, upon not less than three Business Days'
notice to the Administrative Agent, to terminate the Revolving Credit
Commitments or, from time to time, to reduce the aggregate amount of the
Revolving Credit Commitments; provided that no such termination or reduction of
Revolving Credit Commitments shall be permitted if, after giving effect thereto
and to any prepayments of the Revolving Credit Loans made on the effective date
thereof, the Total Revolving Extensions of Credit would exceed the Total
Revolving Credit Commitments. Any such reduction shall be in an amount equal to
$1,000,000, or a whole multiple thereof, and shall reduce permanently the
Revolving Credit Commitments then in effect.

                  (b) The Term Loan Commitments shall be automatically reduced
by $50,000,000 on the Closing Date (upon the making of the Initial Term Loans)
and shall be automatically terminated on the earlier of (i) the Delayed Draw
Borrowing Date (upon the making of the Delayed Draw Term Loans) and (ii) the
last day of the Delayed Draw Commitment Period.

                  2.10     Optional Prepayments. Subject to Consolidated
Liquidity being no less than $35,000,000 (after giving effect to such
prepayment), the Borrower may at any time and from time to time prepay the
Loans, in whole or in part, without premium or penalty (except as otherwise
provided herein), upon irrevocable notice delivered to the Administrative Agent
at least three Business Days prior thereto in the case of Eurodollar Loans and
at least one Business Day prior thereto in the case of Base Rate Loans, which
notice shall specify the date and amount of such prepayment, whether such
prepayment is of Term Loans or Revolving Credit Loans, and whether such
prepayment is of Eurodollar Loans or Base Rate Loans; provided, that if a
Eurodollar Loan is prepaid on any day other than the last day of the Interest
Period applicable thereto, the Borrower shall also pay any amounts owing
pursuant to Section 2.20. Upon receipt of any such notice the Administrative
Agent shall promptly notify each relevant Lender thereof. If any such notice is
given, the amount specified in such notice shall be due and payable on the date
specified therein, together with (except in the case of Revolving Credit Loans
that are Base

<PAGE>
                                                                              30

Rate Loans) accrued interest to such date on the amount prepaid. Partial
prepayments of Term Loans and Revolving Credit Loans shall be in an aggregate
principal amount of $1,000,000 or a whole multiple thereof.

                  2.11     Mandatory Prepayments. (a) If, at any time during the
Revolving Credit Commitment Period, the amount of the Total Revolving Extensions
of Credit exceeds the lesser of (i) the Borrowing Base and (ii) the Total
Revolving Credit Commitments then in effect (whether as a result of the sale of
assets included in the Borrowing Base or otherwise), the Borrower shall, without
notice or demand, prepay, in accordance with this Section, the Revolving Credit
Loans in an aggregate principal amount equal to such excess, together (except in
the case of Revolving Credit Loans which are Base Rate Loans) with interest
accrued to the date of such payment or prepayment; provided that if the
aggregate principal amount of Revolving Credit Loans then outstanding is less
than the amount of such excess (because L/C Obligations constitute a portion
thereof), the Borrower shall, to the extent of the balance of such excess,
replace outstanding Letters of Credit and/or cash collateralize such Letters of
Credit in the manner described in Section 3.10(ii).

                  (b) Unless the Required Prepayment Lenders shall otherwise
agree, if any Capital Stock shall be issued, or Indebtedness incurred, by the
Borrower or any of its Subsidiaries (excluding any Indebtedness incurred in
accordance with Section 7.2), then on the date of such issuance or incurrence,
the Loans shall be prepaid by an amount equal to the amount of the Net Cash
Proceeds of such issuance or incurrence, as set forth in Section 2.11(e). The
provisions of this Section do not constitute a consent to the issuance of any
equity securities by any entity whose equity securities are pledged pursuant to
the Guarantee and Collateral Agreement, or a consent to the incurrence of any
Indebtedness by the Borrower or any of its Subsidiaries.

                  (c) Unless the Required Prepayment Lenders shall otherwise
agree, if on any date the Borrower or any of its Subsidiaries shall receive Net
Cash Proceeds from any Asset Sale or Recovery Event (except (i) a Recovery Event
in respect of any asset held in connection with the continuing operations of the
Borrower and (ii) any Asset Sale pursuant to Section 7.5(f), in each case to the
extent that a Reinvestment Notice shall be delivered in respect thereof), then
on the date of receipt by the Borrower of such Net Cash Proceeds, the Loans
shall be prepaid by an amount equal to the amount of such Net Cash Proceeds, as
set forth in Section 2.11(e); provided, that, notwithstanding the foregoing, (i)
on each Reinvestment Prepayment Date the Loans shall be prepaid by an amount
equal to the Reinvestment Prepayment Amount with respect to the relevant
Reinvestment Event, as set forth in Section 2.11(e) and (ii) so long as no
Revolving Credit Loans are outstanding at the time of receipt thereof, Net Cash
Proceeds of Asset Sales and Recovery Events (other than in respect of [Nigerian
Rig]) in an aggregate amount not to exceed $50,000,000 shall not be required to
be reinvested or applied toward prepayment of the Term Loans to the extent that
an amount of other cash of the Borrower equal to the amount of such Net Cash
Proceeds plus $10,000,000 has been used or is used at such time to prepay the
Existing Convertible Notes or has been placed or is placed at such time in
escrow (pursuant to documentation reasonably satisfactory to the Designated
Agents) for such purpose. The provisions of this Section do not constitute a
consent to the consummation of any Disposition not permitted by Section 7.5.

                                                                              31

                  (d) Unless the Required Prepayment Lenders shall otherwise
agree, if, for any fiscal year of the Borrower commencing with the fiscal year
ending December 31, 2004, there shall be Excess Cash Flow, then, on the relevant
Excess Cash Flow Application Date, the Loans shall be prepaid by an amount equal
to 75% of such Excess Cash Flow, as set forth in Section 2.11(e). Each such
prepayment shall be made on a date (an "Excess Cash Flow Application Date") no
later than fifteen days after the earlier of (i) the date on which the financial
statements of the Borrower referred to in Section 6.1(a), for the fiscal year
with respect to which such prepayment is made, are required to be delivered to
the Lenders and (ii) the date such financial statements are actually delivered.

                  (e) Amounts to be applied in connection with prepayments and
Commitment reductions made pursuant to paragraphs (b), (c) and (d) of this
Section shall be applied, first, to the prepayment of the Term Loans and,
second, to the prepayment of the Revolving Credit Loans, in each case as
provided in Section 2.17.

                  2.12     Conversion and Continuation Options. (a) The Borrower
may elect from time to time to convert Eurodollar Loans to Base Rate Loans by
giving the Administrative Agent at least two Business Days' prior irrevocable
notice of such election, provided that any such conversion of Eurodollar Loans
may be made only on the last day of an Interest Period with respect thereto. The
Borrower may elect from time to time to convert Base Rate Loans to Eurodollar
Loans by giving the Administrative Agent at least three Business Days' prior
irrevocable notice of such election (which notice shall specify the length of
the initial Interest Period therefor), provided that no Base Rate Loan under a
particular Facility may be converted into a Eurodollar Loan (i) when any Event
of Default has occurred and is continuing and the Administrative Agent has, or
the Majority Facility Lenders in respect of such Facility have, determined in
its or their sole discretion not to permit such conversions or (ii) after the
date that is one month prior to the final scheduled termination or maturity date
of such Facility. Upon receipt of any such notice the Administrative Agent shall
promptly notify each relevant Lender thereof.

                  (b) The Borrower may elect to continue any Eurodollar Loan as
such upon the expiration of the then current Interest Period with respect
thereto by giving irrevocable notice to the Administrative Agent, in accordance
with the applicable provisions of the term "Interest Period" set forth in
Section 1.1, of the length of the next Interest Period to be applicable to such
Loans, provided that no Eurodollar Loan under a particular Facility may be
continued as such (i) when any Event of Default has occurred and is continuing
and the Administrative Agent has, or the Majority Facility Lenders in respect of
such Facility have, determined in its or their sole discretion not to permit
such continuations or (ii) after the date that is one month prior to the final
scheduled termination or maturity date of such Facility, and provided, further,
that if the Borrower shall fail to give any required notice as described above
in this paragraph or if such continuation is not permitted pursuant to the
preceding proviso, such Loans shall be converted automatically to Base Rate
Loans on the last day of such then expiring Interest Period. Upon receipt of any
such notice the Administrative Agent shall promptly notify each relevant Lender
thereof.

                  2.13     Minimum Amounts and Maximum Number of Eurodollar
Tranches. Notwithstanding anything to the contrary in this Agreement, all
borrowings, conversions,

<PAGE>
                                                                              32

continuations and optional prepayments of Eurodollar Loans and all selections of
Interest Periods shall be in such amounts and be made pursuant to such elections
so that, (a) after giving effect thereto, the aggregate principal amount of the
Eurodollar Loans comprising each Eurodollar Tranche under the Term Loan Facility
shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof
and (b) no more than ten Eurodollar Tranches shall be outstanding at any one
time (no more than five of which shall be outstanding under the Revolving Credit
Facility).

                  2.14     Interest Rates and Payment Dates. (a) Each Eurodollar
Loan shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin in effect for such day.

                  (b) Each Base Rate Loan shall bear interest for each day on
which it is outstanding at a rate per annum equal to the Base Rate in effect for
such day plus the Applicable Margin in effect for such day.

                  (c) (i) If all or a portion of the principal amount of any
Loan or Reimbursement Obligation shall not be paid when due (whether at the
stated maturity, by acceleration or otherwise), all outstanding Loans and
Reimbursement Obligations (whether or not overdue) (to the extent legally
permitted) shall bear interest at a rate per annum that is equal to (x) in the
case of the Loans, the rate that would otherwise be applicable thereto pursuant
to the foregoing provisions of this Section plus 2% or (y) in the case of
Reimbursement Obligations, the rate applicable to Base Rate Loans under the
Revolving Credit Facility plus 2%, and (ii) if all or a portion of any interest
payable on any Loan or Reimbursement Obligation or any commitment fee or other
amount payable hereunder shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum equal to the rate then applicable to Base Rate Loans under
the relevant Facility plus 2% (or, in the case of any such other amounts that do
not relate to a particular Facility, the rate then applicable to Base Rate Loans
under the Revolving Credit Facility plus 2%), in each case, with respect to
clauses (i) and (ii) above, from the date of such non-payment until such amount
is paid in full (after as well as before judgment).

                  (d) Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to paragraph (c) of this
Section shall be payable from time to time on demand.

                  2.15     Computation of Interest and Fees. (a) Interest, fees,
commissions payable pursuant hereto shall be calculated on the basis of a
360-day year for the actual days elapsed, except that, with respect to Base Rate
Loans on which interest is calculated on the basis of the Prime Rate, the
interest thereon shall be calculated on the basis of a 365- (or 366-, as the
case may be) day year for the actual days elapsed. The Administrative Agent
shall as soon as practicable notify the Borrower and the relevant Lenders of
each determination of a Eurodollar Rate. Any change in the interest rate on a
Loan resulting from a change in the Base Rate or the Eurocurrency Reserve
Requirements shall become effective as of the opening of business on the day on
which such change becomes effective. The Administrative Agent shall as soon as
practicable notify the Borrower and the relevant Lenders of the effective date
and the amount of each such change in interest rate.

<PAGE>
                                                                              33

                  (b) Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error. The Administrative Agent shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the
Administrative Agent in determining any interest rate pursuant to Section
2.15(a).

                  2.16     Inability to Determine Interest Rate. If prior to the
first day of any Interest Period:

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

                  (b) the Administrative Agent shall have received notice from
the Majority Facility Lenders in respect of the relevant Facility that the
Eurodollar Rate determined or to be determined for such Interest Period will not
adequately and fairly reflect the cost to such Lenders (as conclusively
certified by such Lenders) of making or maintaining their affected Loans during
such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the relevant Lenders as soon as practicable thereafter. If such
notice is given (x) any Eurodollar Loans under the relevant Facility requested
to be made on the first day of such Interest Period shall be made as Base Rate
Loans, (y) any Loans under the relevant Facility that were to have been
converted on the first day of such Interest Period to Eurodollar Loans shall be
continued as Base Rate Loans and (z) any outstanding Eurodollar Loans under the
relevant Facility shall be converted, on the last day of the then current
Interest Period with respect thereto, to Base Rate Loans. Until such notice has
been withdrawn by the Administrative Agent, no further Eurodollar Loans under
the relevant Facility shall be made or continued as such, nor shall the Borrower
have the right to convert Loans under the relevant Facility to Eurodollar Loans.

                  2.17     Pro Rata Treatment and Payments. (a) Each borrowing
by the Borrower from the Lenders hereunder, each payment by the Borrower on
account of any commitment fee or Letter of Credit fee, and any reduction of the
Commitments of the Lenders, shall be made pro rata according to the respective
Term Loan Percentages or Revolving Credit Percentages, as the case may be, of
the relevant Lenders.

                  (b) Each payment (including each prepayment) of principal or
interest in respect of the Term Loans shall be allocated among the Term Loan
Lenders pro rata based on the principal amount of the Term Loans held by such
Lenders, and such payments of principal shall be applied to the installments of
the Term Loans pro rata based on the remaining outstanding principal amount of
such installments. Amounts prepaid on account of the Term Loans may not be
reborrowed.

                  (c) Each payment (including each prepayment) by the Borrower
on account of principal of and interest on the Revolving Credit Loans shall be
made pro rata according to the respective outstanding principal amounts of the
Revolving Credit Loans then held by the

<PAGE>
                                                                              34

Revolving Credit Lenders. Each payment in respect of Reimbursement Obligations
in respect of any Letter of Credit shall be made to the Issuing Lender that
issued such Letters of Credit.

                  (d) The application of any payment of Loans under any Facility
(including optional and mandatory prepayments) shall be made, first, to Base
Rate Loans under such Facility and, second, to Eurodollar Loans under such
Facility. Each payment of the Loans (except in the case of Revolving Credit
Loans that are Base Rate Loans) shall be accompanied by accrued interest to the
date of such payment on the amount paid.

                  (e) All payments (including prepayments) to be made by the
Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without setoff or counterclaim and shall be made prior
to 12:00 Noon, New York City time, on the due date thereof to the Administrative
Agent, for the account of the relevant Lenders, at the Payment Office, in
Dollars and in immediately available funds. Any payment made by the Borrower
after 12:00 Noon, New York City time, on any Business Day shall be deemed to
have been on the next following Business Day. The Administrative Agent shall
distribute such payments to the Lenders promptly upon receipt in like funds as
received. If any payment hereunder (other than payments on the Eurodollar Loans)
becomes due and payable on a day other than a Business Day, such payment shall
be extended to the next succeeding Business Day. If any payment on a Eurodollar
Loan becomes due and payable on a day other than a Business Day, the maturity
thereof shall be extended to the next succeeding Business Day unless the result
of such extension would be to extend such payment into another calendar month,
in which event such payment shall be made on the immediately preceding Business
Day. In the case of any extension of any payment of principal pursuant to the
preceding two sentences, interest thereon shall be payable at the then
applicable rate during such extension.

                  (f) Unless the Administrative Agent shall have been notified
in writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to the Administrative Agent, on demand, such amount with interest thereon at a
rate equal to the daily average Federal Funds Effective Rate for the period
until such Lender makes such amount immediately available to the Administrative
Agent. A certificate of the Administrative Agent submitted to any Lender with
respect to any amounts owing under this paragraph shall be conclusive in the
absence of manifest error. If such Lender's share of such borrowing is not made
available to the Administrative Agent by such Lender within three Business Days
after such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
Base Rate Loans under the relevant Facility, on demand, from the Borrower.

                  (g) Unless the Administrative Agent shall have been notified
in writing by the Borrower prior to the date of any payment due to be made by
the Borrower hereunder that the Borrower will not make such payment to the
Administrative Agent, the Administrative Agent may assume that the Borrower is
making such payment, and the Administrative Agent may, but

                                                                              35

shall not be required to, in reliance upon such assumption, make available to
the Lenders their respective pro rata shares of a corresponding amount. If such
payment is not made to the Administrative Agent by the Borrower within three
Business Days after such due date, the Administrative Agent shall be entitled to
recover, on demand, from each Lender to which any amount which was made
available pursuant to the preceding sentence, such amount with interest thereon
at the rate per annum equal to the daily average Federal Funds Effective Rate.
Nothing herein shall be deemed to limit the rights of the Administrative Agent
or any Lender against the Borrower.

                  (h) Notwithstanding any other provision of this Agreement or
any other Loan Document, any proceeds of any foreclosure or other realization by
the Collateral Agent in respect of any Collateral shall be applied as provided
in the Guarantee and Collateral Agreement.

                  2.18     Requirements of Law. (a) If the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
or compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

                           (i)      shall subject any Lender to any tax of any
                                    kind whatsoever with respect to this
                                    Agreement, any Letter of Credit, any
                                    Application or any Eurodollar Loan made by
                                    it, or change the basis of taxation of
                                    payments to such Lender in respect thereof
                                    (except for Non-Excluded Taxes covered by
                                    Section 2.19 and changes in the rate of tax
                                    on the overall net income of such Lender);

                           (ii)     shall impose, modify or hold applicable any
                                    reserve, special deposit, compulsory loan or
                                    similar requirement against assets held by,
                                    deposits or other liabilities in or for the
                                    account of, advances, loans or other
                                    extensions of credit by, or any other
                                    acquisition of funds by, any office of such
                                    Lender that is not otherwise included in the
                                    determination of the Eurodollar Rate
                                    hereunder; or

                           (iii)    shall impose on such Lender any other
                                    condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit, or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, the Borrower shall promptly pay such Lender,
upon its demand, any additional amounts necessary to compensate such Lender for
such increased cost or reduced amount receivable. If any Lender becomes entitled
to claim any additional amounts pursuant to this Section, it shall promptly
notify the Borrower (with a copy to the Administrative Agent) of the event by
reason of which it has become so entitled.

                  (b) If any Lender shall have determined that the adoption of
or any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any

<PAGE>
                                                                              36

Governmental Authority made subsequent to the date hereof shall have the effect
of reducing the rate of return on such Lender's or such corporation's capital as
a consequence of its obligations hereunder or under or in respect of any Letter
of Credit to a level below that which such Lender or such corporation could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the Borrower (with a copy to the Administrative
Agent) of a written request therefor, the Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender or such corporation
for such reduction.

                  (c) A certificate as to any additional amounts payable
pursuant to this Section submitted by any Lender to the Borrower (with a copy to
the Administrative Agent) shall be conclusive in the absence of manifest error.
The obligations of the Borrower pursuant to this Section shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

                  2.19     Taxes. (a) All payments made by the Borrower under
this Agreement shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise taxes imposed
on any Agent or any Lender as a result of a present or former connection between
such Agent or such Lender and the jurisdiction of the Governmental Authority
imposing such tax or any political subdivision or taxing authority thereof or
therein (other than any such connection arising solely from such Agent's or such
Lender's having executed, delivered or performed its obligations or received a
payment under, or enforced, this Agreement or any other Loan Document). If any
such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("Non-Excluded Taxes") or any Other Taxes are required to be
withheld from any amounts payable to any Agent or any Lender hereunder, the
amounts so payable to such Agent or such Lender shall be increased to the extent
necessary to yield to such Agent or such Lender (after payment of all
Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Agreement; provided,
however, that the Borrower shall not be required to increase any such amounts
payable to any Lender with respect to any Non-Excluded Taxes (i) that are
attributable to such Lender's failure to comply with the requirements of
paragraph (d) or (e) of this Section or (ii) that are United States withholding
taxes imposed on amounts payable to such Lender at the time such Lender becomes
a party to this Agreement, except to the extent that such Lender's assignor (if
any) was entitled, at the time of assignment, to receive additional amounts from
the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph
(a).

                  (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

                  (c) Whenever any Non-Excluded Taxes or Other Taxes are payable
by the Borrower, as promptly as possible thereafter the Borrower shall send to
the Administrative Agent for the account of the relevant Agent or Lender, as the
case may be, a certified copy of an original official receipt received by the
Borrower showing payment thereof. If the Borrower

<PAGE>
                                                                              37

fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate
taxing authority or fails to remit to the Administrative Agent the required
receipts or other required documentary evidence, the Borrower shall indemnify
the Agents and the Lenders for any incremental taxes, interest or penalties that
may become payable by any Agent or any Lender as a result of any such failure.
The agreements in this Section shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

                  (d) Each Lender (or Transferee) that is not a citizen or
resident of the United States of America, a corporation, partnership or other
entity created or organized in or under the laws of the United States of America
(or any jurisdiction thereof), or any estate or trust that is subject to federal
income taxation regardless of the source of its income (a "Non-U.S. Lender")
shall deliver to the Borrower and the Administrative Agent (or, in the case of a
Participant, to the Lender from which the related participation shall have been
purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or
Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S.
federal withholding tax under Section 871(h) or 881(c) of the Code with respect
to payments of "portfolio interest" a statement substantially in the form of
Exhibit I and a Form W-8BEN, or any subsequent versions thereof or successors
thereto properly completed and duly executed by such Non-U.S. Lender claiming
complete exemption from, or a reduced rate of, U.S. federal withholding tax on
all payments by the Borrower under this Agreement and the other Loan Documents.
Such forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of any Participant, on or
before the date such Participant purchases the related participation). In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower (or any other form of certification
adopted by the U.S. taxing authorities for such purpose). Notwithstanding any
other provision of this paragraph, a Non-U.S. Lender shall not be required to
deliver any form pursuant to this paragraph that such Non-U.S. Lender is not
legally able to deliver.

                  (e) A Lender that is entitled to an exemption from or
reduction of non-U.S. withholding tax under the law of the jurisdiction in which
the Borrower is located, or any treaty to which such jurisdiction is a party,
with respect to payments under this Agreement shall deliver to the Borrower
(with a copy to the Administrative Agent), at the time or times prescribed by
applicable law or reasonably requested by the Borrower, such properly completed
and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate, provided that such
Lender is legally entitled to complete, execute and deliver such documentation
and in such Lender's reasonable judgment such completion, execution or
submission would not materially prejudice the legal position of such Lender.

                  2.20     Indemnity. The Borrower agrees to indemnify each
Lender for, and to hold each Lender harmless from, any loss (other than loss of
anticipated profits) or expense that such Lender may sustain or incur as a
consequence of (a) default by the Borrower in making a borrowing of, conversion
into or continuation of Eurodollar Loans after the Borrower has given a

<PAGE>
                                                                              38

notice requesting the same in accordance with the provisions of this Agreement,
(b) default by the Borrower in making any prepayment of Eurodollar Loans after
the Borrower has given a notice thereof in accordance with the provisions of
this Agreement or (c) the making of a prepayment or conversion of Eurodollar
Loans on a day that is not the last day of an Interest Period with respect
thereto. A certificate as to any amounts payable pursuant to this Section
submitted to the Borrower by any Lender shall be conclusive in the absence of
manifest error. This covenant shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

                  2.21     Illegality. Notwithstanding any other provision
herein, if the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall
forthwith be suspended for the duration of such illegality and (b) such Lender's
Loans then outstanding as Eurodollar Loans, if any, shall be converted
automatically to Base Rate Loans on the respective last days of the then current
Interest Periods with respect to such Loans or within such earlier period as
required by law. If any such conversion of a Eurodollar Loan occurs on a day
which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to Section 2.20.

                  2.22     Change of Lending Office. Each Lender agrees that,
upon the occurrence of any event giving rise to the operation of Section 2.18,
2.19(a) or 2.21 with respect to such Lender, it will, if requested by the
Borrower, use reasonable efforts (subject to overall policy considerations of
such Lender) to designate another lending office for any Loans affected by such
event with the object of avoiding the consequences of such event; provided, that
such designation is made on terms that, in the sole judgment of such Lender,
cause such Lender and its lending office(s) to suffer no economic, legal or
regulatory disadvantage, and provided, further, that nothing in this Section
shall affect or postpone any of the obligations of any Borrower or the rights of
any Lender pursuant to Section 2.18, 2.19(a) or 2.21.

                  2.23     Replacement of Lenders under Certain Circumstances.
The Borrower shall be permitted to replace any Lender that (a) requests
reimbursement for amounts owing pursuant to Section 2.18 or 2.19 or gives a
notice of illegality pursuant to Section 2.21 or (b) defaults in its obligation
to make Loans hereunder, with a replacement financial institution; provided that
(i) such replacement does not conflict with any Requirement of Law, (ii) no
Event of Default shall have occurred and be continuing at the time of such
replacement, (iii) prior to any such replacement, such Lender shall have taken
no action under Section 2.22 so as to eliminate the continued need for payment
of amounts owing pursuant to Section 2.18 or 2.19 or to eliminate the illegality
referred to in such notice of illegality given pursuant to Section 2.21, (iv)
the replacement financial institution shall purchase, at par, all Loans and
other amounts owing to such replaced Lender on or prior to the date of
replacement, (v) the Borrower shall be liable to such replaced Lender under
Section 2.20 (as though Section 2.20 were applicable) if any Eurodollar Loan
owing to such replaced Lender shall be purchased other than on the last day of
the Interest Period relating thereto, (vi) the replacement financial
institution, if not already a Lender, shall be reasonably satisfactory to the
Administrative Agent, (vii) the replaced Lender shall be obligated to make such
replacement in accordance with the provisions of Section 10.6 (provided that the
replacement financial institution shall be obligated to pay the registration and
processing fee referred to therein), (viii) the Borrower shall pay all
additional amounts (if any)

<PAGE>
                                                                              39

required pursuant to Section 2.18 or 2.19, as the case may be, in respect of any
period prior to the date on which such replacement shall be consummated, (ix) in
the event the replaced Lender is an Issuing Lender, the outstanding Letters of
Credit issued by such replaced Lender shall be replaced and/or
cash-collateralized in an amount and manner satisfactory to such replaced Lender
and (x) any such replacement shall not be deemed to be a waiver of any rights
that the Borrower, the Administrative Agent or any other Lender shall have
against the replaced Lender.

                  2.24     Bank Products. The Borrower may request and any
Lender or Affiliate of any Lender may, in its sole and absolute discretion,
arrange for the Borrower to obtain from such Lender or such Affiliate Bank
Products (which shall be subject to all rules and regulations of such Lender or
such Affiliate) although the Borrower is not required to do so.

                          SECTION 3. LETTERS OF CREDIT

                  3.1      L/C Commitment. (a) Prior to the date hereof, the
Existing Issuing Lender has issued the Existing Letters of Credit which, from
and after the Closing Date, shall constitute Letters of Credit hereunder.
Subject to the terms and conditions hereof, each Issuing Lender, in reliance on
the agreements of the other Revolving Credit Lenders set forth in Section
3.4(a), agrees to issue letters of credit (the letters of credit issued on and
after the Closing Date pursuant to this Section 3, together with the Existing
Letters of Credit collectively, "Letters of Credit") for the account of the
Borrower on any Business Day during the Revolving Credit Commitment Period in
such form as may be approved from time to time by such Issuing Lender; provided,
that no Issuing Lender shall have any obligation to issue any Letter of Credit
if, after giving effect to such issuance, (i) the L/C Obligations would exceed
the L/C Commitment or (ii) the aggregate amount of the Available Revolving
Credit Commitments would be less than zero. Each Letter of Credit shall (i) be
denominated in Dollars and (ii) expire no later than the earlier of (x) the
first anniversary of its date of issuance and (y) the date which is five
Business Days prior to the Revolving Credit Termination Date; provided that any
Letter of Credit with a one-year term may provide for the renewal thereof for
additional one-year periods (which shall in no event extend beyond the date
referred to in clause (y) above).

                  (b) No Issuing Lender shall at any time be obligated to issue
any Letter of Credit hereunder if such issuance would conflict with, or cause
such Issuing Lender or any L/C Participant to exceed any limits imposed by, any
applicable Requirement of Law.

                  3.2      Procedure for Issuance of Letter of Credit. The
Borrower may from time to time request that an Issuing Lender issue a Letter of
Credit by delivering to such Issuing Lender at its address for notices specified
herein an Application therefor, completed to the satisfaction of such Issuing
Lender, and such other certificates, documents and other papers and information
as such Issuing Lender may request. Concurrently with the delivery of an
Application to an Issuing Lender, the Borrower shall deliver a copy thereof to
the Administrative Agent. Upon receipt of any Application, an Issuing Lender
will process such Application and the certificates, documents and other papers
and information delivered to it in connection therewith in accordance with its
customary procedures and shall promptly issue the Letter of Credit requested
thereby by issuing the original of such Letter of Credit to the beneficiary
thereof or as otherwise may be agreed to by such Issuing Lender and the Borrower
(but in no event shall any Issuing Lender be required to issue any Letter of
Credit earlier than two Business Days after

<PAGE>
                                                                              40

its receipt of the Application therefor and all such other certificates,
documents and other papers and information relating thereto). Promptly after
issuance by an Issuing Lender of a Letter of Credit, such Issuing Lender shall
furnish a copy of such Letter of Credit to the Borrower. Each Issuing Lender
shall promptly give notice to the Administrative Agent of the issuance of each
Letter of Credit issued by such Issuing Lender (including the amount thereof),
and shall provide a copy of such Letter of Credit to the Administrative Agent as
soon as possible after the date of issuance.

                  3.3      Fees and Other Charges. (a) The Borrower will pay to
the Administrative Agent for distribution to the Revolving Credit Lenders a fee
on the aggregate drawable amount of all outstanding Letters of Credit at a per
annum rate equal to the Applicable Margin then in effect with respect to
Eurodollar Loans under the Revolving Credit Facility, to be shared ratably among
the Revolving Credit Lenders in accordance with their respective Revolving
Credit Percentages and payable quarterly in arrears on each L/C Fee Payment Date
after the issuance date. In addition, the Borrower shall pay to the relevant
Issuing Lender for its own account a fronting fee on the aggregate drawable
amount of all outstanding Letters of Credit issued by it at the rate per annum
agreed upon from time to time by the Borrower and such Issuing Lender, payable
quarterly in arrears on each L/C Fee Payment Date after the issuance date.

                  (b) In addition to the foregoing fees, the Borrower shall pay
or reimburse each Issuing Lender for such normal and customary costs and
expenses as are incurred or charged by such Issuing Lender in issuing,
negotiating, effecting payment under, amending or otherwise administering any
Letter of Credit.

                  3.4      L/C Participations. (a) Each Issuing Lender
irrevocably agrees to grant and hereby grants to each L/C Participant, and, to
induce each Issuing Lender to issue Letters of Credit hereunder, each L/C
Participant irrevocably agrees to accept and purchase and hereby accepts and
purchases, without recourse or warranty, from each Issuing Lender, on the terms
and conditions hereinafter stated, for such L/C Participant's own account and
risk, an undivided interest equal to such L/C Participant's Revolving Credit
Percentage in each Issuing Lender's obligations and rights under each Letter of
Credit issued by such Issuing Lender hereunder and the amount of each draft paid
by such Issuing Lender thereunder. Each L/C Participant unconditionally and
irrevocably agrees with each Issuing Lender that, if a draft is paid under any
Letter of Credit issued by such Issuing Lender for which such Issuing Lender is
not reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such L/C Participant shall pay to the Administrative Agent for the
account of such Issuing Lender upon demand at such Issuing Lender's address for
notices specified herein (and thereafter the Administrative Agent shall promptly
pay to such Issuing Lender) an amount equal to such L/C Participant's Revolving
Credit Percentage of the amount of such draft, or any part thereof, that is not
so reimbursed.

                  (b) If any amount (a "Participation Amount") required to be
paid by any L/C Participant to an Issuing Lender pursuant to Section 3.4(a) in
respect of any unreimbursed portion of any payment made by such Issuing Lender
under any Letter of Credit is paid to such Issuing Lender within three Business
Days after the date such payment is due, such Issuing Lender shall so notify the
L/C Participants, and each L/C Participant shall pay to Administrative Agent,
for the account of such Issuing Lender, on demand (and thereafter the
Administrative

<PAGE>
                                                                              41

Agent shall promptly pay to such Issuing Lender) an amount equal to the product
of (i) such Participation Amount, times (ii) the daily average Federal Funds
Effective Rate during the period from and including the date such payment is
required to the date on which such payment is immediately available to such
Issuing Lender, times (iii) a fraction the numerator of which is the number of
days that elapse during such period and the denominator of which is 360. If any
Participation Amount required to be paid by any L/C Participant pursuant to
Section 3.4(a) is not made available to the Administrative Agent for the account
of the relevant Issuing Lender by such L/C Participant within three Business
Days after the date such payment is due, the Administrative Agent on behalf of
such Issuing Lender shall be entitled to recover from such L/C Participant, on
demand, such Participation Amount with interest thereon calculated from such due
date at the rate per annum applicable to Base Rate Loans under the Revolving
Credit Facility. A certificate of the Administrative Agent on behalf of an
Issuing Lender submitted to any L/C Participant with respect to any amounts
owing under this Section shall be conclusive in the absence of manifest error.

                  (c) Whenever, at any time after an Issuing Lender has made
payment under any Letter of Credit and has received from the Administrative
Agent any L/C Participant's its pro rata share of such payment in accordance
with Section 3.4(a), such Issuing Lender receives any payment related to such
Letter of Credit (whether directly from the Borrower or otherwise, including
proceeds of collateral applied thereto by such Issuing Lender), or any payment
of interest on account thereof, such Issuing Lender will distribute to the
Administrative Agent for the account of such L/C Participant (and thereafter the
Administrative Agent will promptly distribute to such L/C Participant) its pro
rata share thereof; provided, however, that in the event that any such payment
received by such Issuing Lender shall be required to be returned by such Issuing
Lender, such L/C Participant shall return to the Administrative Agent for the
account of such Issuing Lender (and thereafter the Administrative Agent shall
promptly return to such Issuing Lender) the portion thereof previously
distributed by such Issuing Lender.

                  3.5      Reimbursement Obligation of the Borrower. The
Borrower agrees to reimburse each Issuing Lender, on each date on which such
Issuing Lender notifies the Borrower of the date and amount of a draft presented
under any Letter of Credit and paid by such Issuing Lender, for the amount of
(a) such draft so paid and (b) any taxes, fees, charges or other costs or
expenses incurred by such Issuing Lender in connection with such payment (the
amounts described in the foregoing clauses (a) and (b) in respect of any
drawing, collectively, the "Payment Amount"). Each such payment shall be made to
such Issuing Lender at its address for notices specified herein in lawful money
of the United States of America and in immediately available funds. Interest
shall be payable on each Payment Amount from the date of the applicable drawing
until payment in full at the rate set forth in (i) until the second Business Day
following the date of the applicable drawing, Section 2.14(b) and (ii)
thereafter, Section 2.14(c). Each drawing under any Letter of Credit shall
(unless an event of the type described in clause (i) or (ii) of Section 8(f)
shall have occurred and be continuing with respect to the Borrower, in which
case the procedures specified in Section 3.4 for funding by L/C Participants
shall apply) constitute a request by the Borrower to the Administrative Agent
for a borrowing pursuant to Section 2.5 of Base Rate Loans in the amount of such
drawing. The Borrowing Date with respect to such borrowing shall be the first
date on which a borrowing of Revolving Credit Loans could be made, pursuant to
Section 2.5, if the Administrative Agent had received a notice of such

<PAGE>
                                                                              42

borrowing at the time the Administrative Agent receives notice from the relevant
Issuing Lender of such drawing under such Letter of Credit.

                  3.6      Obligations Absolute. The Borrower's obligations
under this Section 3 shall be absolute and unconditional under any and all
circumstances and irrespective of any setoff, counterclaim or defense to payment
that the Borrower may have or have had against any Issuing Lender, any
beneficiary of a Letter of Credit or any other Person. The Borrower also agrees
with each Issuing Lender that such Issuing Lender shall not be responsible for,
and the Borrower's Reimbursement Obligations under Section 3.5 shall not be
affected by, among other things, the validity or genuineness of documents or of
any endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or any dispute between or among the Borrower and
any beneficiary of any Letter of Credit or any other party to which such Letter
of Credit may be transferred or any claims whatsoever of the Borrower against
any beneficiary of such Letter of Credit or any such transferee. No Issuing
Lender shall be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions found by a final and nonappealable decision of a court of competent
jurisdiction to have resulted from the gross negligence or willful misconduct of
such Issuing Lender. The Borrower agrees that any action taken or omitted by an
Issuing Lender under or in connection with any Letter of Credit issued by it or
the related drafts or documents, if done in the absence of gross negligence or
willful misconduct and in accordance with the standards or care specified in the
Uniform Commercial Code of the State of New York, shall not excuse the
Reimbursement Obligations of the Borrower hereunder and shall not result in any
liability of such Issuing Lender to the Borrower.

                  3.7      Letter of Credit Payments. If any draft shall be
presented for payment under any Letter of Credit, the relevant Issuing Lender
shall promptly notify the Borrower and the Administrative Agent of the date and
amount thereof. The responsibility of the relevant Issuing Lender to the
Borrower in connection with any draft presented for payment under any Letter of
Credit, in addition to any payment obligation expressly provided for in such
Letter of Credit issued by such Issuing Lender, shall be limited to determining
that the documents (including each draft) delivered under such Letter of Credit
in connection with such presentment appear on their face to be in conformity
with such Letter of Credit.

                  3.8      Applications. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall apply.

                  3.9      Indemnification; Exoneration; Power of Attorney.

                  (a)      Indemnification. IN ADDITION TO AMOUNTS PAYABLE AS
         ELSEWHERE PROVIDED IN THIS SECTION, THE BORROWER HEREBY AGREES TO
         PROTECT, INDEMNIFY, PAY AND SAVE THE LENDERS AND THE AGENTS HARMLESS
         FROM AND AGAINST ANY AND ALL CLAIMS, DEMANDS, LIABILITIES, DAMAGES,
         LOSSES, COSTS, CHARGES AND EXPENSES (INCLUDING REASONABLE ATTORNEYS'
         FEES) WHICH ANY LENDER OR ANY AGENT (OTHER THAN ANY LENDER IN ITS
         CAPACITY AS

<PAGE>
                                                                              43

         AN ISSUING LENDER) MAY INCUR OR BE SUBJECT TO AS A CONSEQUENCE, DIRECT
         OR INDIRECT, OF THE ISSUANCE OF ANY LETTER OF CREDIT OTHER THAN ANY
         CLAIMS, DEMANDS, LIABILITIES, DAMAGES, LOSSES, COSTS, CHARGES, AND
         EXPENSES RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL
         MISCONDUCT OF ANY SUCH INDEMNIFIED PERSON. THE AGREEMENT IN THIS
         SECTION SHALL SURVIVE PAYMENT OF ALL OBLIGATIONS. NOTHING CONTAINED IN
         THIS AGREEMENT IS INTENDED TO LIMIT THE BORROWER'S RIGHTS, IF ANY, WITH
         RESPECT TO ANY ISSUING LENDER WHICH ARISE BY OPERATION OF LAW OR AS A
         RESULT OF THE APPLICATION AND RELATED DOCUMENTS EXECUTED BY AND BETWEEN
         THE BORROWER AND ANY ISSUING LENDER.

                  (b)      Assumption of Risk by the Borrower. As among the Loan
         Parties, the Lenders, the Issuing Lenders and the Agents, the Borrower
         or the relevant Loan Party assumes all risks of the acts and omissions
         of, or misuse of any of the Letters of Credit by, the respective
         beneficiaries of such Letters of Credit. In furtherance and not in
         limitation of the foregoing, the Lenders, the Issuing Lenders and the
         Agents shall not be responsible for: (i) the form, validity,
         sufficiency, accuracy, genuineness or legal effect of any document
         submitted by any Person in connection with the application for and
         issuance of and presentation of drafts with respect to any of the
         Letters of Credit, even if it should prove to be in any or all respects
         invalid, insufficient, inaccurate, fraudulent or forged; (ii) the
         validity or sufficiency of any instrument transferring or assigning or
         purporting to transfer or assign any 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) the failure of
         the beneficiary of any Letter of Credit to comply duly with conditions
         required in order to draw upon such Letter of Credit; (iv) errors,
         omissions, interruptions, or delays in transmission or delivery of any
         messages, by mail, cable, telegraph, telex or otherwise, whether or not
         they be in cipher; (v) errors in interpretation of technical terms;
         (vi) any loss or delay in the transmission or otherwise of any document
         required in order make a drawing under any Letter of Credit or of the
         proceeds thereof; (vii) the misapplication by the beneficiary of any
         Letter of Credit of the proceeds of any drawing under such Letter of
         Credit; or (viii) any consequences arising from causes beyond the
         control of the Lenders, the Issuing Lenders or the Agents, including
         any act or omission, whether rightful or wrongful, of any present or
         future de jure or de facto Governmental Authority. None of the
         foregoing shall affect, impair or prevent the vesting of any rights or
         powers of any Agent, any Issuing Lender or any Lender under this
         Section.

                  (c)      Exoneration. In furtherance and extension, and not in
         limitation, of the specific provisions set forth above, any action
         taken or omitted by any Agent, any Issuing Lender or any Lender under
         or in connection with any of the Letters of Credit or any related
         certificates, if taken or omitted in good faith, shall not put any
         Agent, any Issuing Lender or any Lender under any resulting liability
         to any Loan Party or relieve the relevant Loan Party of any of its
         obligations hereunder to any such Person.

                  (d)      Indemnification by Lenders. The Revolving Credit
         Lenders agree to indemnify each Issuing Lender (to the extent not
         reimbursed by the Borrower and

<PAGE>
                                                                              44

         without limiting the obligations of the Borrower hereunder) ratably in
         accordance with their respective Revolving Credit Percentages in effect
         on the date on which indemnification is sought under this Section (or,
         if indemnification is sought after the date upon which the Commitments
         shall be terminated and the Revolving Credit Loans shall have been paid
         in full, ratably in accordance with such Revolving Credit Percentages
         immediately prior to such date), for any and all liabilities,
         obligations, losses, damages, penalties, actions, judgments, suits,
         costs, expenses (including attorneys' fees) or disbursements of any
         kind and nature whatsoever that may be imposed on, incurred by or
         asserted against such Issuing Lender in any way relating to or arising
         out of any Letter of Credit or the transactions contemplated thereby or
         any action taken or omitted by such Issuing Lender under any Letter of
         Credit or any Loan Document in connection therewith; provided that no
         Lender shall be liable for any of the foregoing to the extent it arises
         from the gross negligence or willful misconduct of the Person to be
         indemnified. Without limitation of the foregoing, each Revolving Credit
         Lender agrees to reimburse each Issuing Lender promptly upon demand for
         its Revolving Credit Percentage of any costs or expenses payable by the
         Borrower to such Issuing Lender, to the extent that such Issuing Lender
         is not promptly reimbursed for such costs and expenses by the Borrower.
         The agreement contained in this Section shall survive payment in full
         of all Obligations.

                  (e)      Power of Attorney. In connection with all inventory
         financed by Letters of Credit, the Borrower hereby appoints each
         Issuing Lender, or such Issuing Lender's designee, as its attorney,
         with full power and authority: (i) to sign and/or endorse the
         Borrower's name upon any warehouse or other receipts; (ii) to sign the
         Borrower's name on bills of lading and other negotiable and
         non-negotiable documents; (iii) to clear inventory through customs in
         such Issuing Lender's or the Borrower's name, and to sign and deliver
         to customs officials powers of attorney in the Borrower's name for such
         purpose; (iv) to complete in the Borrower's or such Issuing Lender's
         name, any order, sale, or transaction, obtain the necessary documents
         in connection therewith, and collect the proceeds thereof; and (v) to
         do such other acts and things as are necessary in order to enable such
         Issuing Lender to obtain possession or control of the inventory and to
         obtain payment of the Revolving Credit Facility Obligations (as defined
         in the Guarantee and Collateral Agreement). None of the Issuing Lenders
         or any of their respective designees, as the Borrower's attorney, will
         be liable for any acts or omissions, nor for any error of judgment or
         mistakes of fact or law. This power, being coupled with an interest, is
         irrevocable until all Revolving Credit Facility Obligations have been
         paid and satisfied.

                  (f)      Account Party. The Borrower hereby authorizes and
         directs any Issuing Lender to name the Borrower as the "Account Party"
         therein and to deliver to the Collateral Agent all instruments,
         documents and other writings and property received by such Issuing
         Lender pursuant to the Letter of Credit, and to accept and rely upon
         the Collateral Agent's instructions and agreements with respect to all
         matters arising in connection with the Letter of Credit or the
         Application therefor.

                  3.10     Supporting Letter of Credit; Cash Collateral. If,
notwithstanding the provisions of this Section and Section 8, any Letter of
Credit is outstanding upon the termination of this Agreement, then upon such
termination the Borrower shall deposit with the Administrative Agent, for the
ratable benefit of the Issuing Lenders and the Revolving Credit

<PAGE>
                                                                              45

Lenders, with respect to each Letter of Credit then outstanding, as the Majority
Revolving Credit Facility Lenders in their discretion shall specify, either (i)
a standby letter of credit (a "Supporting Letter of Credit") in form and
substance satisfactory to the Administrative Agent, issued by an issuer
satisfactory to the Administrative Agent in an amount equal to the greatest
amount for which such Letter of Credit may be drawn plus any fees and expenses
associated with such Letter of Credit, under which Supporting Letter of Credit
the Administrative Agent is entitled to draw amounts necessary to reimburse the
Administrative Agent, the Issuing Lenders and the Revolving Credit Lenders for
payments to be made under or in connection with such Letter of Credit and any
fees and expenses associated with such Letter of Credit, or (ii) cash in amounts
necessary to reimburse the Administrative Agent, the Issuing Lenders and the
Revolving Credit Lenders for payments made under or in connection with such
Letter of Credit and any fees and expenses associated with such Letter of
Credit. Such Supporting Letter of Credit or deposit of cash shall be held by the
Administrative Agent, for the ratable benefit of the Administrative Agent, the
Issuing Lenders and the Revolving Credit Lenders, as security for, and to
provide for the payment of, the aggregate undrawn amount of such Letters of
Credit remaining outstanding. Reasonable interest shall accrue on any such cash
deposit, which accrued interest shall be for the account of the Borrower,
subject to this Agreement.

                    SECTION 4. REPRESENTATIONS AND WARRANTIES

                  To induce the Agents and the Lenders to enter into this
Agreement and to make the Loans and issue or participate in the Letters of
Credit, the Borrower hereby represents and warrants to each Agent and each
Lender that:

                  4.1      Financial Condition. (a) The unaudited pro forma
consolidated balance sheet of the Borrower and its consolidated Subsidiaries as
at June 30, 2003 (including the notes thereto) (the "Pro Forma Balance Sheet"),
copies of which have heretofore been furnished to the Administrative Agent
(which shall make such copies available to each Lender), has been prepared
giving effect (as if such events had occurred on such date) to (i) the Loans to
be made and the Senior Notes to be issued on the Closing Date and the use of
proceeds thereof and (ii) the payment of fees and expenses in connection with
the foregoing. The Pro Forma Balance Sheet has been prepared based on the
information available to the Borrower as of the date of delivery thereof, and
presents fairly in all material respects on a pro forma basis the estimated
financial position of Borrower and its consolidated Subsidiaries as at June 30,
2003, assuming that the events specified in the preceding sentence had actually
occurred at such date.

                  (b) The audited consolidated balance sheets of the Borrower as
at December 31, 2001 and December 31, 2002, and the related consolidated
statements of income and of cash flows for the fiscal years ended on such dates,
reported on by and accompanied by an unqualified report from
PricewaterhouseCoopers LLP, present fairly in all material respects the
consolidated financial condition of the Borrower as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
respective fiscal years then ended. The unaudited consolidated balance sheets of
the Borrower as at March 31, 2003 and June 30, 2003, and the related unaudited
consolidated statements of income and cash flows for the periods ended on such
date, present fairly in all material respects the consolidated financial
condition of the Borrower as at such dates, and the consolidated results of its
operations and its consolidated cash flows for the quarterly periods then ended
(subject to normal year-end audit adjustments). All

<PAGE>
                                                                              46

such financial statements, including the related schedules and notes thereto,
have been prepared in accordance with GAAP applied consistently throughout the
periods involved (except as approved by the aforementioned firm of accountants
and disclosed therein). The Borrower and its Subsidiaries do not have any
material Guarantee Obligations, contingent liabilities and liabilities for taxes
(except for any such tax liabilities to taxing authorities outside of the United
States which are not, in the aggregate, material to the Borrower and its
Subsidiaries taken as a whole) or any long-term leases or unusual forward or
long-term commitments, including, without limitation, any interest rate or
foreign currency swap or exchange transaction or other obligation in respect of
derivatives, that are not reflected in the most recent financial statements
referred to in this paragraph. During the period from December 31, 2002 to and
including the date hereof there has been no Disposition by the Borrower of any
material part of its business or Property, except as reflected in the foregoing
financial statements.

                  4.2      No Change. Since December 31, 2002 there has been no
development or event that has had or could reasonably be expected to have a
Material Adverse Effect.

                  4.3      Corporate Existence; Compliance with Law. Each of the
Borrower and its Subsidiaries (a) is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization, (b) has
the corporate power and authority, and the legal right, to own and operate its
Property, to lease the Property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of Property or the conduct of its business
requires such qualification except to the extent that the failure to be so
qualified could not reasonably be expected to have a Material Adverse Effect and
(d) is in compliance with all Requirements of Law except to the extent that the
failure to comply therewith could not, in the aggregate, reasonably be expected
to have a Material Adverse Effect.

                                                                              47

                  4.4      Corporate Power; Authorization; Enforceable
Obligations. Each Loan Party has the corporate power and authority, and the
legal right, to make, deliver and perform the Loan Documents to which it is a
party and, in the case of the Borrower, to borrow hereunder. Each Loan Party has
taken all necessary corporate or other action to authorize the execution,
delivery and performance of the Loan Documents to which it is a party and, in
the case of the Borrower, to authorize the borrowings on the terms and
conditions of this Agreement. No consent or authorization of, filing with,
notice to or other act by or in respect of, any Governmental Authority or any
other Person is required in connection with the Refinancing, the borrowings
hereunder or the execution, delivery, performance, validity or enforceability of
this Agreement or any of the other Loan Documents, except (i) consents,
authorizations, filings and notices described in Schedule 4.4, which consents,
authorizations, filings and notices have been obtained or made and are in full
force and effect (except as noted on Schedule 4.19) and (ii) the filings
referred to in Section 4.4. Each Loan Document has been duly executed and
delivered on behalf of each Loan Party that is a party thereto. This Agreement
constitutes, and each other Loan Document upon execution will constitute, a
legal, valid and binding obligation of each Loan Party that is a party thereto,
enforceable against each such Loan Party in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

                  4.5      No Legal Bar. The execution, delivery and performance
of this Agreement and the other Loan Documents, the issuance of Letters of
Credit, the borrowings hereunder and the use of the proceeds thereof will not
violate any Requirement of Law or any Contractual Obligation of the Borrower or
any of its Subsidiaries and will not result in, or require, the creation or
imposition of any Lien on any of their respective properties or revenues
pursuant to any Requirement of Law or any such Contractual Obligation (other
than the Liens created by the Security Documents). No Requirement of Law or
Contractual Obligation applicable to the Borrower or any of its Subsidiaries
could reasonably be expected to have a Material Adverse Effect.

                  4.6      No Material Litigation. No litigation, investigation
or proceeding of or before any arbitrator or Governmental Authority is pending
or, to the knowledge of the Borrower, threatened by or against the Borrower or
any of its Subsidiaries or against any of their respective properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or thereby, or (b) that could reasonably be
expected to have a Material Adverse Effect.

                  4.7      No Default. Neither the Borrower nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect that could reasonably be expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

<PAGE>

                                                                              48

                  4.8      Ownership of Property; Liens. Each of the Borrower
and its Subsidiaries has title in fee simple to, or a valid leasehold interest
in, all its material real property, and good title to, or a valid leasehold
interest in, all its other material Property, and none of such Property is
subject to any Lien except as permitted by Section 7.3.

                  4.9      Intellectual Property. The Borrower and each of its
Subsidiaries owns, or is licensed to use, all material Intellectual Property
necessary for the conduct of its business as currently conducted; no material
claim has been asserted and is pending by any Person challenging or questioning
the use of any such Intellectual Property or the validity or effectiveness of
any such Intellectual Property, nor does the Borrower know of any valid basis
for any such claim; and the use of such Intellectual Property by the Borrower
and its Subsidiaries does not infringe on the rights of any Person in any
material respect.

                  4.10     Taxes. Each of the Borrower and each of its
Subsidiaries has filed or caused to be filed all Federal, state and other
material tax returns that are required to be filed and has paid all taxes shown
to be due and payable on said returns or on any assessments made against it or
any of its Property and all other taxes, fees or other charges imposed on it or
any of its Property by any Governmental Authority (other than any the amount or
validity of which are currently being contested in good faith by appropriate
proceedings and with respect to which reserves in conformity with GAAP have been
provided on the books of the Borrower or its Subsidiaries, as the case may be);
and no tax Lien has been filed, and, to the knowledge of the Borrower, no claim
is being asserted, with respect to any such tax, fee or other charge (other than
any such Liens and claims in favor of taxing authorities outside of the United
States which are not, in the aggregate, material to the Borrower and its
Subsidiaries taken as a whole).

                  4.11     Federal Regulations. No part of the proceeds of any
Loans will be used in violation of Regulation U as now and from time to time
hereafter in effect or for any purpose that violates the provisions of the
Regulations of the Board. If requested by any Lender or the Administrative
Agent, the Borrower will furnish to the Administrative Agent and each Lender a
statement to the foregoing effect in conformity with the requirements of FR Form
G-3 or FR Form U-1 referred to in Regulation U.

                  4.12     Labor Matters. There are no strikes or other labor
disputes against the Borrower or any of its Subsidiaries pending or, to the
knowledge of the Borrower, threatened that (individually or in the aggregate)
could reasonably be expected to have a Material Adverse Effect. Hours worked by
and payment made to employees of the Borrower and its Subsidiaries have not been
in violation of the Fair Labor Standards Act or any other applicable Requirement
of Law dealing with such matters that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect. All payments due from
the Borrower or any of its Subsidiaries on account of employee health and
welfare insurance that (individually or in the aggregate) could reasonably be
expected to have a Material Adverse Effect if not paid have been paid or accrued
as a liability on the books of the Borrower or the relevant Subsidiary.

                  4.13     ERISA. Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with

<PAGE>
                                                                              49

the applicable provisions of ERISA and the Code. No termination of a Single
Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has
arisen, during such five-year period. The present value of all accrued benefits
under each Single Employer Plan (based on those assumptions used to fund such
Plans) did not, as of the last annual valuation date prior to the date on which
this representation is made or deemed made, exceed the value of the assets of
such Plan allocable to such accrued benefits by a material amount. Neither the
Borrower nor any Commonly Controlled Entity has had a complete or partial
withdrawal from any Multiemployer Plan that has resulted or could reasonably be
expected to result in a material liability under ERISA, and neither the Borrower
nor any Commonly Controlled Entity would become subject to any material
liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

                  4.14     Investment Company Act; Other Regulations. No Loan
Party is an "investment company", or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended.
No Loan Party is subject to regulation under any Requirement of Law (other than
Regulation X of the Board) which limits its ability to incur Indebtedness.

                  4.15     Subsidiaries. (a) The Subsidiaries listed on Schedule
4.15 constitute all of the Subsidiaries of the Borrower at the date hereof.
Schedule 4.15 sets forth as of the Closing Date the name and jurisdiction of
incorporation of each such Subsidiary and, as to each, the percentage of each
class of Capital Stock owned by each Loan Party.

                  (b)      As of the date hereof, there are no outstanding
subscriptions, options, warrants, calls, rights or other agreements or
commitments (other than stock options granted to employees or directors and
directors' qualifying shares) of any nature relating to any Capital Stock of the
Borrower or any Subsidiary, except as disclosed on Schedule 4.15.

                  4.16     Use of Proceeds. The proceeds of the Initial Term
Loans shall be used to repay, repurchase, redeem, defease or otherwise retire a
portion of the 9.75% Senior Notes and to pay related fees and expenses. The
proceeds of the Delayed Draw Term Loans shall be used to repay, repurchase,
redeem, defease or otherwise retire a portion of the Existing Convertible Notes
and to pay related fees and expenses. The proceeds of the Revolving Credit
Loans, and the Letters of Credit, shall be used for the general corporate
purposes of the Borrower and its Subsidiaries.

                  4.17     Environmental Matters. Other than as set forth on
Schedule 4.17 and exceptions to any of the following that could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect:

                  (a) The Borrower and its Subsidiaries: (i) are, and within the
period of all applicable statutes of limitation have been, in compliance with
all applicable Environmental Laws; (ii) hold all Environmental Permits (each of
which is in full force and effect) required for any of their current or intended
operations or for any property owned, leased, or otherwise operated by any of
them; (iii) are, and within the period of all applicable statutes of limitation

<PAGE>
                                                                              50

have been, in compliance with all of their Environmental Permits; and (iv)
reasonably believe that: each of their Environmental Permits will be timely
renewed and complied with, without material expense; any additional
Environmental Permits that may be required of any of them will be timely
obtained and complied with, without material expense; and compliance with any
Environmental Law that is or is expected to become applicable to any of them
will be timely attained and maintained, without material expense.

                  (b) Materials of Environmental Concern are not present at, on,
under, in, or about any real property now or formerly owned, leased or operated
by the Borrower or any of its Subsidiaries, or at any other location (including,
without limitation, any location to which Materials of Environmental Concern
have been sent for re-use or recycling or for treatment, storage, or disposal)
which could reasonably be expected to (i) give rise to liability of the Borrower
or any of its Subsidiaries under any applicable Environmental Law or otherwise
result in costs to the Borrower or any of its Subsidiaries, or (ii) interfere
with the Borrower's or any of its Subsidiaries' continued operations, or (iii)
impair the fair saleable value of any real property owned or leased by the
Borrower or any of its Subsidiaries.

                  (c) There is no judicial, administrative, or arbitral
proceeding (including any notice of violation or alleged violation) under or
relating to any Environmental Law to which the Borrower or any of its
Subsidiaries is, or to the knowledge of the Borrower or any of its Subsidiaries

benefit of its creditors; or (ii) there shall be commenced against the Borrower

to, or proceedings shall commence to have a trustee appointed, or a trustee
shall be appointed, to administer or to terminate, any Single Employer Plan,

in the termination of such Plan for purposes of Title IV of ERISA, (iv) any
Single Employer Plan shall terminate for purposes of Title IV of ERISA, (v) the
Borrower or any Commonly Controlled Entity shall incur any liability in
connection with a withdrawal from, or the Insolvency or Reorganization of, a
Multiemployer Plan or (vi) any other event or condition shall occur or exist
with respect to a Plan; and in each case in clauses (i) through (vi) above, such
event or condition, together with all other such events or conditions, if any,

                  (h) One or more judgments or decrees shall be entered against

                                                                              74

then, and in any such event, (A) if such event is an Event of Default specified

automatically the Commitments shall immediately terminate and the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Loan Documents (including, without limitation, all
amounts of L/C Obligations, whether or not the beneficiaries of the then
outstanding Letters of Credit shall have presented the documents required
thereunder) shall immediately become due and payable, and (B) if such event is
any other Event of Default, either or both of the following actions may be
taken: (i) with the consent of the Majority Revolving Credit Facility Lenders,
the Administrative Agent may, or upon the request of the Majority Revolving
Credit Facility Lenders, the Administrative Agent shall, by notice to the
Borrower declare the Revolving Credit Commitments to be terminated forthwith,
whereupon the Revolving Credit Commitments shall immediately terminate; (ii)
with the consent of the Majority Term Loan Facility Lenders, the Administrative
Agent may, or upon the request of the Majority Term Loan Facility Lenders, the
Administrative Agent shall, by notice to the Borrower declare the Term Loan
Commitments to be terminated forthwith, whereupon the Term Loan Commitments
shall immediately terminate; and (iii) with the consent of the Required Lenders,
the Administrative Agent may, or upon the request of the Required Lenders, the
Administrative Agent shall, by notice to the Borrower, declare the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Loan Documents (including, without limitation, all
amounts of L/C Obligations, whether or not the beneficiaries of the then
outstanding Letters of Credit shall have presented the documents required
thereunder) to be due and payable forthwith, whereupon the same shall
immediately become due and payable. In the case of all Letters of Credit with
respect to which presentment for honor shall not have occurred at the time of an
acceleration pursuant to this paragraph, the Borrower shall at such time deposit
in a cash collateral account opened by the Administrative Agent an amount equal
to the aggregate then undrawn and unexpired amount of such Letters of Credit.
Amounts held in such cash collateral account shall be applied by the
Administrative Agent to the payment of drafts drawn under such Letters of
Credit, and the unused portion thereof after all such Letters of Credit shall
have expired or been fully drawn upon, if any, shall be applied to repay other
obligations of the Borrower hereunder and under the other Loan Documents. After
all such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations of
the Borrower hereunder and under the other Loan Documents shall have been paid
in full, the balance, if any, in such cash collateral account shall be returned
to the Borrower (or such other Person as may be lawfully entitled thereto).

                           SECTION 9. THE AGENTS

                  9.1      Appointment. Each Lender hereby irrevocably
designates and appoints the Agents as the agents of such Lender under this
Agreement and the other Loan Documents, and each Lender irrevocably authorizes
each Agent, in such capacity, to take such action on its behalf under the
provisions of this Agreement and the other Loan Documents and to exercise such
powers and perform such duties as are expressly delegated to such Agent by the
terms of this Agreement and the other Loan Documents, together with such other
powers as are reasonably incidental thereto. Notwithstanding any provision to
the contrary elsewhere in this Agreement, no Agent shall have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against any Agent.

                  9.2      Delegation of Duties. Each Agent may execute any of
its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. No Agent shall be responsible
for the negligence or misconduct of any agents or attorneys-in-fact selected by
it with reasonable care.

                  9.3      Exculpatory Provisions. Neither any Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or affiliates
shall be (i) liable for any action lawfully taken or omitted to be taken by it
or such Person under or in connection with this Agreement or any other Loan
Document (except to the extent that any of the foregoing are found by a final
and nonappealable decision of a court of competent jurisdiction to have resulted
from its or such Person's own gross negligence or willful misconduct) or (ii)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by any Loan Party or any officer thereof
contained in this Agreement or any other Loan Document or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Agents under or in connection with, this Agreement or any other Loan
Document or for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document or for any failure
of any Loan Party to perform its obligations hereunder or thereunder. The Agents
shall not be under any obligation to any Lender to ascertain or to inquire as to
the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of any Loan Party.

                  9.4      Reliance by Agents. Each Agent shall be entitled to
rely, and shall be fully protected in relying, upon any instrument, writing,
resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to the Loan Parties), independent accountants and
other experts selected by such Agent. The Agents may deem and treat the payee of
any Note as the owner thereof for all purposes unless such Note shall have been
transferred in accordance with Section 10.6 and all actions required by such
Section in connection with such transfer shall have been taken. Each Agent shall
be fully justified in failing or refusing to take any action under this
Agreement or any

<PAGE>
                                                                              76

other Loan Document unless it shall first receive such advice or concurrence of
the Required Lenders (or, if so specified by this Agreement, all Lenders or any
other instructing group of Lenders specified by this Agreement) as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense that may be incurred by it by reason
of taking or continuing to take any such action. Each Agent shall in all cases
be fully protected in acting, or in refraining from acting, under this Agreement
and the other Loan Documents in accordance with a request of the Required
Lenders (or, if so specified by this Agreement, all Lenders or any other
instructing group of Lenders specified by this Agreement), and such request and
any action taken or failure to act pursuant thereto shall be binding upon all
the Lenders and all future holders of the Loans.

                  9.5      Notice of Default. No Agent shall be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless such Agent shall have received notice from a Lender or the
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". In the event that
the Administrative Agent shall receive such a notice, the Administrative Agent
shall give notice thereof to the Lenders. The Administrative Agent shall take
such action with respect to such Default or Event of Default as shall be
reasonably directed by the Required Lenders (or, if so specified by this
Agreement, all Lenders or any other instructing group of Lenders specified by
this Agreement); provided that unless and until the Administrative Agent shall
have received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable in the best
interests of the Lenders.

                  9.6      Non-Reliance on Agents and Other Lenders. Each Lender
expressly acknowledges that neither any of the Agents nor any of their
respective officers, directors, employees, agents, attorneys-in-fact or
affiliates have made any representations or warranties to it and that no act by
any Agent hereafter taken, including any review of the affairs of a Loan Party
or any affiliate of a Loan Party, shall be deemed to constitute any
representation or warranty by any Agent to any Lender. Each Lender represents to
the Agents that it has, independently and without reliance upon any Agent or any
other Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Loan Parties and their affiliates and made its own decision to make its Loans
hereunder and enter into this Agreement. Each Lender also represents that it
will, independently and without reliance upon any Agent or any other Lender, and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in
taking or not taking action under this Agreement and the other Loan Documents,
and to make such investigation as it deems necessary to inform itself as to the
business, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their affiliates. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative Agent hereunder, no Agent shall have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of any Loan Party or any affiliate of
a Loan Party that may come into the possession of such Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates.

                                                                              77

                  9.7      Indemnification. The Lenders agree to indemnify each
Agent in its capacity as such (to the extent not reimbursed by the Borrower and
without limiting the obligation of the Borrower to do so), ratably according to
their respective Aggregate Exposure Percentages in effect on the date on which
indemnification is sought under this Section (or, if indemnification is sought
after the date upon which the Commitments shall have terminated and the Loans
shall have been paid in full, ratably in accordance with such Aggregate Exposure
Percentages immediately prior to such date), for, and to save each Agent
harmless from and against, any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever that may at any time (including, without limitation, at
any time following the payment of the Loans) be imposed on, incurred by or
asserted against such Agent in any way relating to or arising out of, the
Commitments, this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by such Agent
under or in connection with any of the foregoing; provided that no Lender shall
be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements that are found by a final and nonappealable decision of a court of
competent jurisdiction to have resulted from such Agent's gross negligence or
willful misconduct. The agreements in this Section shall survive the payment of
the Loans and all other amounts payable hereunder.

                  9.8      Agent in Its Individual Capacity. Each Agent and its
affiliates may make loans to, accept deposits from and generally engage in any
kind of business with any Loan Party as though such Agent were not an Agent.
With respect to its Loans made or renewed by it and with respect to any Letter
of Credit issued or participated in by it, each Agent shall have the same rights
and powers under this Agreement and the other Loan Documents as any Lender and
may exercise the same as though it were not an Agent, and the terms "Lender" and
"Lenders" shall include each Agent in its individual capacity.

                  9.9      Successor Agents. The Administrative Agent may resign
as Administrative Agent upon 10 days' notice to the Lenders and the Borrower. If
the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Loan Documents, then the Required Lenders shall appoint
from among the Lenders a successor agent for the Lenders, which successor agent
shall (unless an Event of Default under Section 8(a) or Section 8(f) with
respect to the Borrower shall have occurred and be continuing) be subject to
approval by the Borrower (which approval shall not be unreasonably withheld or
delayed), whereupon such successor agent shall succeed to the rights, powers and
duties of the Administrative Agent, and the term "Administrative Agent" shall
mean such successor agent effective upon such appointment and approval, and the
former Administrative Agent's rights, powers and duties as Administrative Agent
shall be terminated, without any other or further act or deed on the part of
such former Administrative Agent or any of the parties to this Agreement or any
holders of the Loans. If no successor agent has accepted appointment as
Administrative Agent by the date that is 10 days following a retiring
Administrative Agent's notice of resignation, the retiring Administrative
Agent's resignation shall nevertheless thereupon become effective, and the
Lenders shall assume and perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
agent as provided for above. The Collateral Agent may, at any time, by notice to
the Lenders and the Administrative Agent, resign as Collateral Agent hereunder,
whereupon (i) its duties, rights,

<PAGE>
                                                                              78

obligations and responsibilities hereunder shall automatically be assumed by,
and inure to the benefit of, the Administrative Agent, without any further act
by the Collateral Agent, the Administrative Agent or any Lender, (ii) the
resigning Collateral Agent shall deliver to the Administrative Agent any
Collateral held by it prior to such resignation, (iii) any liens in favor of the
resigning Collateral Agent shall be assigned by it to the Administrative Agent
and (iv) the Collateral Agent shall take any other action reasonably requested
by the Administrative Agent in connection with such resignation. After any
retiring Agent's resignation as Agent, the provisions of this Section 9 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement and the other Loan Documents.

                  9.10     Authorization to Release Liens and Guarantees. Each
of the Administrative Agent and the Collateral Agent is hereby irrevocably
authorized by each of the Lenders to effect any release of Liens or guarantee
obligations contemplated by Section 10.15.

                  9.11     The Arrangers; the Syndication Agent; the
Documentation Agent. The Arrangers, the Syndication Agent nor the Documentation
Agent, in their respective capacities as such, shall have no duties or
responsibilities, and shall incur no liability, under this Agreement and the
other Loan Documents.

                           SECTION 10. MISCELLANEOUS

                  10.1     Amendments and Waivers. Neither this Agreement or any
other Loan Document, nor any terms hereof or thereof may be amended,

                                    without the consent of each Lender directly
                                    affected thereby;

                                    directly affected thereby;

                           (vii)    amend, modify or waive any provision of
                                    Section 2.17 without the consent of each
                                    Lender directly affected thereby;

                           (viii)   amend, modify or waive any provision of

                           (ix)     impose restrictions on assignments and
                                    participations that are more restrictive
                                    than, or additional to, those set forth in

                                    Lenders;

                           (x)      increase the Advance Rates under the

                                    Lenders whose Revolving Credit Percentages
                                    are no less than 75% in the aggregate.

Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Loan Parties, the
Lenders, the Agents and all future holders of the Loans. In the case of any
waiver, the Loan Parties, the Lenders and the Agents shall be restored to their
former position and rights hereunder and under the other Loan Documents, and any
Default or Event of Default waived shall be deemed to be cured and not
continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default, or impair any right consequent thereon. Any such waiver,
amendment, supplement or modification shall be effected by a written instrument
signed by the parties required to sign pursuant to the foregoing provisions of
this Section; provided, that delivery of an executed signature page of any such
instrument by facsimile transmission shall be effective as delivery of a
manually executed counterpart thereof.

                  10.2     Notices. All notices, requests and demands to or upon
the respective parties hereto to be effective shall be in writing (including by

                  Issuing Lender:            As notified by such Issuing Lender
                                             to the Administrative Agent and the
                                             Borrower

provided that any notice, request or demand to or upon the any Agent, any
Issuing Lender or any Lender shall not be effective until received.

                  10.3     No Waiver; Cumulative Remedies. No failure to
exercise and no delay in exercising, on the part of any Agent or any Lender, any
right, remedy, power or privilege hereunder or under the other Loan Documents
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.
The rights, remedies, powers and privileges herein provided are cumulative and
not exclusive of any rights, remedies, powers and privileges provided by law.

                  10.4     Survival of Representations and Warranties. All
representations and warranties made herein, in the other Loan Documents and in
any document, certificate or statement delivered pursuant hereto or in
connection herewith shall survive the execution and delivery of this Agreement
and the making of the Loans and other extensions of credit hereunder.

                  10.5     Payment of Expenses. The Borrower agrees (a) to pay
or reimburse the Designated Agents for all their reasonable out-of-pocket costs
and expenses incurred in connection with the syndication of the Facilities
(other than fees payable to syndicate members) and the development, preparation
and execution of, and any amendment, supplement or modification to, this
Agreement and the other Loan Documents and any other documents prepared in
connection herewith or therewith, and the consummation and administration of the
transactions contemplated hereby and thereby, including, without limitation, the
reasonable fees and disbursements and other charges of counsel to the
Administrative Agent and the Collateral Agent and the charges of Intralinks, (b)
to pay or reimburse each Lender and the Agents for all their costs and expenses
incurred in connection with the enforcement or preservation of any rights under
this Agreement, the other Loan Documents and any other documents prepared in
connection herewith or therewith, including, without limitation, the fees and
disbursements of counsel (including the allocated fees and disbursements and
other charges of in-house counsel) to each Lender and of counsel to the Agents,
(c) to pay, indemnify, or reimburse each Lender and the Agents for, and hold
each Lender and the Agents harmless from, any and all recording and filing fees
and any and all liabilities with respect to, or resulting from any delay in
paying, stamp, excise and other taxes, if any, which may be payable or
determined to be payable in connection with the execution and delivery of, or
consummation or administration of any of the transactions contemplated by, or
any amendment, supplement or modification of, or any waiver or consent under or
in respect of, this Agreement, the other Loan Documents and any such other
documents, and (d) to pay, indemnify or reimburse each Lender, each Agent, their
respective affiliates, and

<PAGE>
                                                                              82

their respective officers, directors, trustees, employees, advisors, agents and
controlling persons (each, an "Indemnitee") for, and hold each Indemnitee
harmless from and against any and all other liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever with respect to the execution, delivery,
enforcement, performance and administration of this Agreement, the other Loan
Documents and any such other documents, including, without limitation, any of
the foregoing relating to the use of proceeds of the Loans or the violation of,
noncompliance with or liability under, any Environmental Law applicable to the
operations of the Borrower any of its Subsidiaries or any of the Properties and
the fees and disbursements and other charges of legal counsel in connection with
the foregoing (all the foregoing in this clause (d), collectively, the
"Indemnified Liabilities"), provided, that the Borrower shall have no obligation
hereunder to any Indemnitee with respect to Indemnified Liabilities to the
extent such Indemnified Liabilities have resulted from the gross negligence or
willful misconduct of such Indemnitee, and provided further that the Borrower
shall have no obligation hereunder to any Indemnitee which is such an advisor
with respect to losses, damages, liabilities or related expenses of such advisor
in respect of any claims brought by any other Indemnitee against such advisor
arising from the negligence of such advisor in the provision of services to such
other Indemnitee. No Indemnitee shall be liable for any damages arising from the
use by unauthorized persons of Information or other materials sent through
electronic, telecommunications or other information transmission systems that
are intercepted by such persons or for any special, indirect, consequential or
punitive damages in connection with the Facilities. Without limiting the
foregoing, and to the extent permitted by applicable law, the Borrower agrees
not to assert and to cause its Subsidiaries not to assert, and hereby waives and
agrees to cause its Subsidiaries so to waive, all rights for contribution or any
other rights of recovery with respect to all claims, demands, penalties, fines,
liabilities, settlements, damages, costs and expenses of whatever kind or
nature, under or related to Environmental Laws, that any of them might have by
statute or otherwise against any Indemnitee. All amounts due under this Section
shall be payable not later than 30 days after written demand therefor.
Statements payable by the Borrower pursuant to this Section shall be submitted
to the Borrower at the address of the Borrower set forth in Section 10.2, or to
such other Person or address as may be hereafter designated by the Borrower in a
notice to the Administrative Agent. The agreements in this Section shall survive
repayment of the Loans and all other amounts payable hereunder.

                  10.6     Successors and Assigns; Participations and
Assignments. (a) This Agreement shall be binding upon and inure to the benefit
of the Borrower, the Lenders, the Agents, all future holders of the Loans and
their respective successors and assigns, except that the Borrower may not assign
or transfer any of its rights or obligations under this Agreement without the
prior written consent of the Agents and each Lender.

                  (b) Any Lender may, without the consent of the Borrower, in
accordance with applicable law, at any time sell to one or more banks, financial
institutions or other entities (each, a "Participant") participating interests
in any Loan owing to such Lender, any Commitment of such Lender or any other
interest of such Lender hereunder and under the other Loan Documents. In the
event of any such sale by a Lender of a participating interest to a Participant,
such Lender's obligations under this Agreement to the other parties to this
Agreement shall remain unchanged, such Lender shall remain solely responsible
for the performance thereof, such Lender shall remain the holder of any such
Loan for all purposes under this Agreement and the

<PAGE>
                                                                              83

other Loan Documents, and the Borrower and the Agents shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents. In no event shall
any Participant under any such participation have any right to approve any
amendment or waiver of any provision of any Loan Document, or any consent to any
departure by any Loan Party therefrom, except to the extent that such amendment,
waiver or consent would require the consent of the Lender from whom such
Participant purchased such participation pursuant to Section 10.1. The Borrower
agrees that if amounts outstanding under this Agreement and the Loans are due or
unpaid, or shall have been declared or shall have become due and payable upon
the occurrence of an Event of Default, each Participant shall, to the maximum
extent permitted by applicable law, be deemed to have the right of setoff in
respect of its participating interest in amounts owing under this Agreement to
the same extent as if the amount of its participating interest were owing
directly to it as a Lender under this Agreement, provided that, in purchasing
such participating interest, such Participant shall be deemed to have agreed to
share with the Lenders the proceeds thereof as provided in Section 10.7(a) as
fully as if such Participant were a Lender hereunder. The Borrower also agrees
that each Participant shall be entitled to the benefits of Sections 2.18, 2.19
and 2.20 with respect to its participation in the Commitments and the Loans
outstanding from time to time as if such Participant were a Lender; provided
that, in the case of Section 2.19, such Participant shall have complied with the
requirements of said Section, and provided, further, that no Participant shall
be entitled to receive any greater amount pursuant to any such Section than the
transferor Lender would have been entitled to receive in respect of the amount
of the participation transferred by such transferor Lender to such Participant
had no such transfer occurred.

                  (c) Any Lender (an "Assignor") may, in accordance with
applicable law and upon written notice to the Administrative Agent, at any time
and from time to time assign to any Lender or any affiliate, Related Fund or
Control Investment Affiliate thereof or, with the consent of the Borrower and
the Administrative Agent and, in the case of any assignment of Revolving Credit
Commitments, the written consent of the Issuing Lender (which, in each case,
shall not be unreasonably withheld or delayed) (provided (x) that no such
consent need be obtained by the Administrative Agent or any of its Affiliates
and (y) the consent of the Borrower need not be obtained with respect to any
assignment of Term Loans or if an Event of Default shall have occurred and be
continuing), to an additional bank, financial institution or other entity that
is not a competitor of the Borrower or its Subsidiaries (an "Assignee") all or
any part of its rights and obligations under this Agreement pursuant to an
Assignment and Acceptance, substantially in the form of Exhibit E, executed by
such Assignee and such Assignor (and, where the consent of the Borrower, the
Administrative Agent or the Issuing Lender is required pursuant to the foregoing
provisions, by the Borrower and such other Persons) and delivered to the
Administrative Agent for its acceptance and recording in the Register; provided
that ((i) no such assignment to an Assignee (other than any Lender or any
affiliate thereof) shall be in an aggregate principal amount of less than
$2,500,000 (in the case of assignments of the Revolving Credit Facility) or
$1,000,000 (in the case of assignments of the Term Loan Facility) and (ii) after
giving effect thereto, the assigning Lender shall have Revolving Credit
Commitments and Revolving Credit Loans aggregating at least $2,500,000 (in the
case of the Revolving Credit Facility) or Term Loan Commitments and Term Loans
aggregating at least $1,000,000 (in the case of the Term Loan Facility), unless
otherwise agreed by the Borrower and the Administrative Agent (in each case
other than in the case of an assignment of all of a Lender's interests under
such Facility),

<PAGE>
                                                                              84

unless otherwise agreed by the Borrower and the Administrative Agent. Any such
assignment need not be ratable as among the Facilities. Upon such execution,
delivery, acceptance and recording, from and after the effective date determined
pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be
a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder with Commitments and/or
Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent
provided in such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of an Assignor's rights and obligations under this Agreement, such Assignor
shall cease to be a party hereto, except as to Section 2.18, 2.19 and 10.5 in
respect of the period prior to such effective date). Notwithstanding any
provision of this Section, the consent of the Borrower shall not be required for
any assignment that occurs at any time when any Event of Default shall have
occurred and be continuing. For purposes of the minimum assignment amounts set
forth in this paragraph, multiple assignments by or to two or more Related
Funds, or to two or more funds that will be Related Funds after giving effect to
such assignments, shall be aggregated.

                  (d) The Administrative Agent shall, on behalf of the Borrower,
maintain at its address referred to in Section 10.2 a copy of each Assignment
and Acceptance delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Lenders and the Commitment of, and
principal amount of the Loans owing to, each Lender from time to time. The
entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, each Agent and the Lenders shall treat each Person whose name
is recorded in the Register as the owner of the Loans and any Notes evidencing
such Loans recorded therein for all purposes of this Agreement. Any assignment
of any Loan, whether or not evidenced by a Note, shall be effective only upon
appropriate entries with respect thereto being made in the Register (and each
Note shall expressly so provide). Any assignment or transfer of all or part of a
Loan evidenced by a Note shall be registered on the Register only upon surrender
for registration of assignment or transfer of the Note evidencing such Loan,
accompanied by a duly executed Assignment and Acceptance; thereupon one or more
new Notes in the same aggregate principal amount shall be issued to the
designated Assignee, and the old Notes shall be returned by the Administrative
Agent to the Borrower marked "canceled". The Register shall be available for
inspection by the Borrower or any Lender (with respect to any entry relating to
such Lender's Loans) at any reasonable time and from time to time upon
reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
by an Assignor and an Assignee (and, in any case where the consent of any other
Person is required by Section 10.6(c), by each such other Person) together with
payment to the Administrative Agent of a registration and processing fee of
$3,500 (treating multiple, simultaneous assignments by or to two or more Related
Funds, or to two or more funds that will be Related Funds after giving effect to
such assignments, as a single assignment) (except that no such registration and
processing fee shall be payable in the case of an Assignee which is already a
Lender or is an affiliate or Related Fund of a Lender or a Person under common
management with a Lender), the Administrative Agent shall (i) promptly accept
such Assignment and Acceptance and (ii) on the effective date determined
pursuant thereto record the information contained therein in the Register and
give notice of such acceptance and recordation to the Borrower. On or prior to
such effective date, the Borrower, at its own expense, upon request, shall
execute and deliver to the Administrative Agent (in exchange for the Revolving
Credit Note and/or Term Note, as the case

                                                                              85

may be, of the assigning Lender) a new Revolving Credit Note and/or Term Note,
as the case may be, to the order of such Assignee in an amount equal to the
Revolving Credit Commitment and/or Term Loans, as the case may be, assumed or
acquired by it pursuant to such Assignment and Acceptance and, if the Assignor
has retained a Revolving Credit Commitment and/or Term Loans, as the case may
be, upon request, a new Revolving Credit Note and/or Term Note, as the case may
be, to the order of the Assignor in an amount equal to the Revolving Credit
Commitment and/or Term Loans, as the case may be, retained by it hereunder. Such
new Note or Notes shall be dated the Closing Date and shall otherwise be in the
form of the Note or Notes replaced thereby.

                  (f) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this Section concerning assignments of Loans
and Notes relate only to absolute assignments and that such provisions do not
prohibit assignments creating security interests in Loans and Notes, including,
without limitation, any pledge or assignment by a Lender of any Loan or Note to
any Federal Reserve Bank in accordance with applicable law.

                  10.7     Adjustments; Set-off. (a) Except to the extent that
this Agreement provides for payments to be allocated to a particular Lender, if
any Lender (a "Benefitted Lender") shall at any time receive any payment of all
or part of the Obligations owing to it under any Facility, or receive any
collateral in respect thereof (whether voluntarily or involuntarily, by set-off,
pursuant to events or proceedings of the nature referred to in Section 8(f), or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of such other Lender's
Obligations under such Facility, such Benefitted Lender shall purchase for cash
from the other Lenders a participating interest in such portion of each such
other Lender's Obligations under such Facility, or shall provide such other
Lenders with the benefits of any such collateral, as shall be necessary to cause
such Benefitted Lender to share the excess payment or benefits of such
collateral ratably with each of the Lenders under such Facility; provided,
however, that if all or any portion of such excess payment or benefits is
thereafter recovered from such Benefitted Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest.

                  (b) In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder (whether at the stated maturity, by acceleration or
otherwise), to set off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender or any branch or agency
thereof to or for the credit or the account of the Borrower. Each Lender agrees
promptly to notify the Borrower and the Administrative Agent after any such
setoff and application made by such Lender, provided that the failure to give
such notice shall not affect the validity of such setoff and application.

                  10.8     Counterparts. This Agreement may be executed by one
or more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one
and the same instrument. Delivery of an

executed signature page of this Agreement or of a Lender Addendum by facsimile
transmission shall be effective as delivery of a manually executed counterpart
hereof. A set of the copies of this Agreement signed by all the parties shall be
lodged with the Borrower and the Administrative Agent.

                  10.9     Severability. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  10.10    Integration. This Agreement and the other Loan
Documents represent the entire agreement of the Borrower, the Agents, the
Arranger and the Lenders with respect to the subject matter hereof and thereof,
and there are no promises, undertakings, representations or warranties by the
Arranger, any Agent or any Lender relative to subject matter hereof not
expressly set forth or referred to herein or in the other Loan Documents.

                  10.11    GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  10.12    Submission To Jurisdiction; Waivers. The Borrower
hereby irrevocably and unconditionally:

                  (a) submits for itself and its Property in any legal action or
proceeding relating to this Agreement and the other Loan Documents to which it
is a party, or for recognition and enforcement of any judgment in respect
thereof, to the non-exclusive general jurisdiction of the courts of the State of
New York, the courts of the United States of America for the Southern District
of New York, and appellate courts from any thereof;

                  (b) consents that any such action or proceeding may be brought
in such courts and waives any objection that it may now or hereafter have to the
venue of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

                  (c) agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the
Borrower at its address set forth in Section 10.2 or at such other address of
which the Administrative Agent shall have been notified pursuant thereto;

                  (d) agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction; and

                  (e) waives, to the maximum extent not prohibited by law, any
right it may have to claim or recover in any legal action or proceeding referred
to in this Section any special, exemplary, punitive or consequential damages.

                                                                              87

                  10.13    Acknowledgments. The Borrower hereby acknowledges
that:

                  (a) it has been advised by counsel in the negotiation,
execution and delivery of this Agreement and the other Loan Documents;

                  (b) neither the Arranger, any Agent nor any Lender has any
fiduciary relationship with or duty to the Borrower arising out of or in
connection with this Agreement or any of the other Loan Documents, and the
relationship between the Arranger, the Agents and the Lenders, on one hand, and
the Borrower, on the other hand, in connection herewith or therewith is solely
that of debtor and creditor; and

                  (c) no joint venture is created hereby or by the other Loan

among the Arranger, the Agents and the Lenders or among the Borrower and the
Lenders.

                  10.14    Confidentiality. Each of the Agents and the Lenders
agrees to keep confidential all non-public information provided to it by any
Loan Party pursuant to this Agreement that is designated by such Loan Party as
confidential; provided that nothing herein shall prevent any Agent or any Lender
from disclosing any such information (a) to the Arranger, any Agent, any other
Lender or any affiliate of any thereof, (b) to any Participant or Assignee
(each, a "Transferee") or prospective Transferee that agrees to comply with the
provisions of this Section or substantially equivalent provisions, (c) to any of
its employees, directors, agents, attorneys, accountants and other professional
advisors, (d) to any financial institution that is a direct or indirect

professional advisor (so long as such contractual counterparty or professional
advisor to such contractual counterparty agrees to be bound by the provisions of
this Section), (e) upon the request or demand of any Governmental Authority
having jurisdiction over it, (f) in response to any order of any court or other
Governmental Authority or as may otherwise be required pursuant to any

issued with respect to such Lender or (j) in connection with the exercise of any
remedy hereunder or under any other Loan Document. Notwithstanding anything to
the contrary in the foregoing sentence or any other express or implied
agreement, arrangement or understanding, the parties hereto hereby agree that,
from the commencement of discussions with respect to the financing provided
hereunder, any party hereto (and each of its employees, representatives, or
agents) is permitted to disclose to any and all persons, without limitation of
any kind, the tax structure and tax aspects of the transactions contemplated
hereby, and all materials of any kind (including opinions or other tax analyses)
related to such tax structure and tax aspects.

                  10.15    Release of Collateral and Guarantee Obligations.

                  (a) Notwithstanding anything to the contrary contained herein
or in any other Loan Document, promptly upon request of the Borrower in
connection with any Disposition of Property permitted by the Loan Documents, the
Collateral Agent shall (without notice to, or vote

<PAGE>
                                                                              88

or consent of, any Lender, or any party to any Bank Product) take such actions
as shall be required to release its security interest in any Collateral being
Disposed of in such Disposition (including, in the case of a Disposition of any
Person, all Capital Stock of such Person and all Property of such Person), and
the Administrative Agent shall (without notice to, or vote or consent of, any
Lender, or any party to any Bank Product) take such actions as shall be required
to release any guarantee and other obligations under any Loan Document of any
Person being Disposed of in such Disposition. In addition, upon Parker Drilling
Offshore International, Inc., ceasing to guaranty the Senior Notes and the
10.125% Senior Notes, Parker Drilling Offshore International, Inc., shall
automatically be released from its guaranty obligations and any other
obligations under the Loan Documents, and the Administrative Agent shall
(without notice to, or vote or consent of, any Lender or any party to any Bank
Product) take such actions as shall be required or reasonably requested by the
Borrower to evidence such release. At such time as the Term Loans shall have
been repaid in full, the Existing Convertible Notes shall have been repaid in
full and the Consolidated Liquidity shall be not less than an amount to be
agreed upon by the Designated Agents at such time, promptly upon the request of
the Borrower, the Eligible Rental Equipment shall be removed from the Borrowing
Base, the Collateral Agent shall (without notice to, or vote or consent of, any
Lender, or any party to any Bank Product) take such actions as shall be required
to release its security interest in the Quail Rental Assets and the
Administrative Agent shall (without notice to, or vote or consent of, any Lender
or any party to any Bank Product) take such actions as shall be required or
reasonably requested by the Borrower to evidence such release.

                  (b) Notwithstanding anything to the contrary contained herein
or any other Loan Document, when all Obligations (other than obligations in
respect of any Bank Product) have been paid in full, all Commitments have
terminated or expired and no Letter of Credit shall be outstanding, upon request
of the Borrower, the Collateral Agent shall (without notice to, or vote or
consent of, any Lender, or any party to any Bank Product) take such actions as
shall be required to release its security interest in all Collateral, and the
Administrative Agent shall (without notice to, or vote or consent of, any
Lender, or any party to any Bank Product) take such actions as shall be required
to release all guarantee obligations under any Loan Document, whether or not on
the date of such release there may be outstanding Obligations in respect of Bank
Products. Any such release of guarantee obligations shall be deemed subject to
the provision that such guarantee obligations shall be reinstated if after such
release any portion of any payment in respect of the Obligations guaranteed
thereby shall be rescinded or must otherwise be restored or returned upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Borrower or any Guarantor, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or any Guarantor or any substantial part of its property, or otherwise,
all as though such payment had not been made.

                  10.16    Accounting Changes. In the event that any "Accounting
Change" (as defined below) shall occur and such change results in a change in
the method of calculation of financial covenants, standards or terms in this
Agreement, then the Borrower and the Administrative Agent agree to enter into
negotiations in order to amend such provisions of this Agreement so as to
equitably reflect such Accounting Change with the desired result that the
criteria for evaluating the Borrower's financial condition shall be the same
after such Accounting Change as if such Accounting Change had not been made.
Until such time as such an

                                                                              89

amendment shall have been executed and delivered by the Borrower, the
Administrative Agent and the Required Lenders, all financial covenants,
standards and terms in this Agreement shall continue to be calculated or
construed as if such Accounting Change had not occurred. "Accounting Change"
refers to any change in accounting principles required by the promulgation of
any rule, regulation, pronouncement or opinion by the Financial Accounting
Standards Board of the American Institute of Certified Public Accountants or, if
applicable, the SEC.

                  10.17    Delivery of Lender Addenda. Each initial Lender shall
become a party to this Agreement by delivering to the Administrative Agent a
Lender Addendum duly executed by such Lender, the Borrower and the
Administrative Agent.

                  10.18    Usury Not Intended. It is the intent of the Borrower
and each Lender in the execution and performance of this Agreement and the other
Loan Documents to contract in strict compliance with applicable usury laws,
including conflicts of law concepts, from time-to-time in effect governing the
Loans of each Lender. In furtherance thereof, the Lenders and the Borrower
stipulate and agree that none of the terms and provisions contained in this
Agreement or the other Loan Documents shall ever be construed to create a
contract to pay, as consideration for the use, forbearance or detention of
money, interest at a rate in excess of the maximum nonusurious interest rate
under applicable law (the "Maximum Rate") and that for purposes hereof
"interest" shall include the aggregate of all charges which constitute interest
under such laws that are contracted for, charged or received under this
Agreement; and in the event that, notwithstanding the foregoing, under any
circumstances the aggregate amounts taken, reserved, charged, received or paid
on the Loans, include amounts which by applicable law are deemed interest which
would exceed the Maximum Rate, then such excess shall be deemed to be a mistake
and each Lender receiving same shall credit the same on the principal of its
Loans (or if such Loans shall have been paid in full, refund said excess to the
Borrower). In the event that the maturity of any Loans is accelerated by reason
of any election of the holder thereof resulting from any Event of Default under
this Agreement or otherwise, or in the event of any required or permitted
prepayment, then such consideration that constitutes interest may never include
more than the Maximum Rate and excess interest, if any, provided for in this
Agreement or otherwise shall be canceled automatically as of the date of such
acceleration or prepayment and, if theretofore paid, shall be credited on the
applicable Loans (or, if the applicable Loans shall have been paid in full,
refunded to the Borrower). In determining whether or not the interest paid or
payable under any specific contingencies exceeds the Maximum Rate, the Borrower
and the Lenders shall to the maximum extent permitted under applicable law
amortize, prorate, allocate and spread in equal parts during the period of the
full stated term of the Loans all amounts considered to be interest under
applicable law at any time contracted for, charged, received or reserved in
connection with the Obligations. The provisions of this Section 10.18 shall
control over all other provisions of this Agreement or the other Loan Documents
which may be in apparent conflict herewith.

                  10.19    WAIVERS OF JURY TRIAL. THE BORROWER, THE AGENTS AND
THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY
LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
AND FOR ANY COUNTERCLAIM THEREIN.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed and delivered by their proper and duly authorized
officers as of the day and year first above written.

Changes in the Applicable Margin with respect to Revolving Credit Loans
resulting from changes in the Consolidated Leverage Ratio shall become effective
on the date (the "Adjustment Date") on which financial statements are delivered
to the Lenders pursuant to Section 6.1(a) or 6.1(b) (but in any event not later
than the 45th day after the end of each of the first three quarterly periods of
each fiscal year or the 90th day after the end of each fiscal year, as the case
may be) and shall remain in effect until the next change to be effected pursuant
to this paragraph. If any financial statements referred to above are not
delivered within the time periods specified above, then, until such financial
statements are delivered, the Consolidated Leverage Ratio as at the end of the
fiscal period that would have been covered thereby shall for the purposes of
this definition be deemed to be greater than 5.50 to 1:00. Each determination of
the Consolidated Leverage Ratio pursuant to this Pricing Grid shall be made for
the periods and in the manner contemplated by Section 7.1(a).

waived, surrendered or released by any Agent or any Secured Party (to the extent
permitted by the Loan Documents and the Bank Products), and the Bank Products,

executed and delivered in connection therewith may be amended, modified,
supplemented or terminated, in whole or in part, as the Agents (or the relevant

offset at any time held by any Agent or any Secured Party for the payment of the

waived, surrendered or released. Neither any Agent nor any Secured Party shall,
except to the extent set forth in, and for the benefit of the parties to, the

notice of or proof of reliance by any Agent or any Secured Party upon the
guarantee contained in this Section 2 or acceptance of the guarantee contained
in this Section 2; the Borrower Obligations, and any of them, shall conclusively
be deemed to have been created, contracted or incurred, or renewed, extended,
amended or waived, in reliance upon the guarantee contained in this Section 2;
and all dealings between the Borrower and any of the Guarantors, on the one
hand, and the Agents and the Secured Parties, on the other hand, likewise shall
be conclusively presumed to have been had or consummated in reliance upon the
guarantee contained in this Section 2. Each Guarantor waives diligence,
presentment, protest, demand for payment and notice of default or nonpayment to
or upon the Borrower or any of the Guarantors with respect to the Borrower
Obligations (other than any diligence, presentment, protest, demand or notice
with respect to any Guarantor Bank Product Obligation with respect to which such
Guarantor is a primary obligor and to which it is entitled pursuant to the
applicable Bank Product). Each Guarantor understands and agrees that the
guarantee of such Guarantor contained in this Section 2 shall be construed as a
continuing, absolute and unconditional guarantee of payment without regard to
(a) the validity or enforceability of the Credit Agreement or any other Loan
Document, any of the Borrower Obligations or any collateral security therefor or
guarantee or right of offset with respect thereto at any time or from time to
time held by any Agent or any Secured Party, (b) any defense, set-off or
counterclaim (other than a defense of payment or performance) which may at any
time be available to or be asserted by the Borrower or any other Person against
any Agent or any Secured Party, or (c) any other circumstance whatsoever (with
or without notice to or knowledge of the Borrower or such Guarantor) which
constitutes, or might be construed to constitute, an equitable or legal
discharge of the Borrower for the Borrower Obligations, or of such Guarantor
under the guarantee of such Guarantor contained in this Section 2, in bankruptcy
or in any other instance. When making any demand hereunder or otherwise pursuing
its rights and remedies hereunder against any Guarantor, any Agent or any
Secured Party may, but shall be under no obligation to, make a similar demand on
or otherwise pursue such rights and remedies as it may have against the

other Person or against any collateral security or guarantee for the Borrower
Obligations or any right of offset with respect thereto, and any failure by any
Agent or any Secured Party to make any such demand, to pursue such other rights
or remedies or to collect any payments from the Borrower, any other Guarantor or
any other Person or to realize upon any such collateral security or guarantee or
to exercise any such right of offset, or any release of the Borrower, any other
Guarantor or any other Person or any such collateral security, guarantee or
right of offset, shall not relieve any Guarantor of any obligation or liability
under this Section 2, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of any Agent or any
Secured Party against any Guarantor. For the purposes hereof "demand" shall
include the commencement and continuance of any legal proceedings.

         (b)      The Borrower waives any and all notice of the creation,
renewal, extension or accrual of any of the Guarantor Bank Product Obligations
and notice of or proof of reliance by the Administrative Agent or any Secured
Party upon the guarantee by the Borrower contained in this Section 2 or
acceptance of the guarantee by the Borrower contained in this Section 2; the
Guarantor Bank Product Obligations, and any of them, shall conclusively be
deemed to have been created, contracted or incurred, or renewed, extended,
amended or waived, in reliance upon the guarantee by the Borrower contained in
this Section 2; and all dealings between the Borrower and any of the Guarantors,
on the one hand, and the Agents and the Secured Parties, on the other hand, with
respect to any Guarantor Bank Product Obligation likewise shall be conclusively
presumed to have been had or consummated in reliance upon the guarantee by the
Borrower contained in this Section 2. The Borrower waives diligence,
presentment, protest, demand for payment and notice of default or nonpayment to
or upon the Borrower with respect to the Guarantor Bank Product Obligations. The
Borrower understands and agrees that the guarantee by the Borrower contained in
this Section 2 shall be construed as a continuing, absolute and unconditional
guarantee of payment without regard to (a) the validity or enforceability of the
Guarantor Bank Product Obligations or any other collateral security therefor or
guarantee or right of offset with respect thereto at any time or from time to
time held by any Agent or any Secured Party, (b) any defense, set-off or
counterclaim (other than a defense of payment or performance) which may at any
time be available to or be asserted by any Person against any Agent or any
Secured Party, or (c) any other circumstance whatsoever (with or without notice
to or knowledge of the Borrower or any Guarantor) which constitutes, or might be
construed to constitute, an equitable or legal discharge of the applicable
Guarantor for the applicable Guarantor Bank Product Obligations, or of the
Borrower under its guarantee contained in this Section 2, in bankruptcy or in
any other instance. When making any demand under this Section 2 or otherwise
pursuing its rights and remedies under this Section 2 against the Borrower, any
Agent or any Secured Party may, but shall be under no obligation to, make a
similar demand on or otherwise pursue such rights and remedies as it may have
against any Guarantor or any other Person or against any collateral security or
guarantee for the Guarantor Bank Product Obligations or any right of offset with
respect thereto, and any failure by any Agent or any Secured Party to make any
such demand, to pursue such other rights or remedies or to collect any payments
from any Guarantor or any other Person or to realize upon any such collateral
security or guarantee or to exercise any such right of offset, or any release of
any Guarantor or any other Person or any such collateral security, guarantee or
right of offset, shall not relieve the Borrower of any obligation or liability
under this Section 2, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of any Agent or any
Secured

Party against the Borrower under this Section 2. For the purposes hereof
"demand" shall include the commencement and continuance of any legal
proceedings.

                  2.6 Reinstatement. The guarantee contained in this Section 2
shall continue to be effective, or be reinstated, as the case may be, if at any
time payment, or any part thereof, of any of the Borrower Obligations or
Guarantor Bank Product Obligations is rescinded or must otherwise be restored or
returned by the Administrative Agent or any Secured Party upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Borrower or any
Guarantor, or upon or as a result of the appointment of a receiver, intervenor
or conservator of, or trustee or similar officer for, the Borrower or any
Guarantor or any substantial part of its property, or otherwise, all as though
such payments had not been made. The provisions of this Section 2.6 shall
survive termination of this Agreement.

                  2.7 Payments. The Borrower and each Guarantor hereby
guarantees that payments by it hereunder will be paid (i) in the case of
obligations in respect of Borrower Obligations arising under the Credit
Agreement or any other Loan Document, to the Administrative Agent without
set-off or counterclaim in Dollars at the Payment Office specified in the Credit
Agreement and (ii) in the case of obligations in respect of any Borrower Bank
Product Obligations or any Guarantor Bank Product Obligations, to the relevant
Secured Party in the currency and at the place specified in the applicable Bank

each Lender shall be entitled to rely on each of them as if they were fully set

warranty to the Borrower's knowledge shall, for the purposes of this Section
4.1, be deemed to be a reference to such Guarantor's knowledge.

                  4.2 Title; No Other Liens. Except for the security interests
granted to the Collateral Agent for the benefit of the Secured Parties pursuant
to this Agreement and the other Liens permitted to exist on the Collateral by
the Credit Agreement, such Grantor owns each item of the Collateral free and

                  4.3 Perfected First Priority Liens. The security interests
granted pursuant to this Agreement (a) upon completion of the filings and other

interests in all of the Collateral in favor of the Collateral Agent, for the
benefit of the Secured Parties, as collateral security for such Grantor's
Obligations, enforceable in accordance with the terms hereof against all
creditors of such Grantor and any Persons purporting to purchase any Collateral
from such Grantor and (b) (i) in the case of the First Priority Interests, are
prior to all other Liens on the Collateral in existence on the date hereof
except for the Liens permitted by the Credit Agreement and (ii) in the case of
the Second Priority Interests, are prior to all other Liens on the Collateral in

representations are made with respect to the requirements of any laws of any
jurisdiction other than the United States or any State thereof.

outstanding Foreign Subsidiary Voting Stock of each relevant Issuer.

                  (b) All the shares of the Pledged Stock have been duly and
validly issued and are fully paid and nonassessable.

                  (c) Each of the Pledged Notes constitutes the legal, valid and
binding obligation of the obligor with respect thereto, enforceable in
accordance with its terms, subject to the effects of bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other similar laws
relating to or affecting creditors' rights generally, general equitable
principles (whether considered in a proceeding in equity or at law) and an
implied covenant of good faith and fair dealing.

                  (d) Such Grantor is the record and beneficial owner of, and
has good title to the Investment Property pledged by it hereunder, free of any
and all Liens or options in favor of, or claims of, any other Person, except the
security interest created by this Agreement and other Liens permitted by the

requirements of any laws of any jurisdiction other than the United States or any
State thereof.

Governmental Authority which would limit, cancel or question the validity of, or

                  (e) No action or proceeding is pending, or, to the knowledge
of such Grantor, threatened, on the date hereof (i) seeking to limit, cancel or
question the validity of any such Intellectual Property or such Grantor's
ownership interest therein, or (ii) which, if adversely determined, would
reasonably be expected to have a Material Adverse Effect.

Guarantor, such Guarantor shall take, or shall refrain from taking, as the case

action or to refrain from taking such action by such Guarantor or any of its
Subsidiaries.

                  5.2 Delivery of Instruments and Chattel Paper. If any amount
payable under or in connection with any of the Collateral shall be or become
evidenced by any Instrument, Certificated Security or Chattel Paper, such
Instrument, Certificated Security or Chattel Paper shall be immediately
delivered to the Collateral Agent, duly indorsed in a manner satisfactory to the

similar business.

                  (b) Within a reasonable period of time (as determined by the
Designated Agents), such Grantor shall cause the Collateral Agent to be named as

                  (c) The Borrower shall deliver to the Designated Agents and
the Lenders a report of a reputable insurance broker with respect to such
insurance substantially concurrently with the delivery by the Borrower to the
Designated Agents of its audited financial statements for each fiscal year and

and the Lenders promptly, in reasonable detail, of:

                  (a) any Lien (other than security interests created hereby or
Liens permitted under the Credit Agreement) on any of the Collateral which would
adversely affect the ability of the Collateral Agent to exercise any of its
remedies hereunder; and

                  (b) the occurrence of any other event which could reasonably
be expected to have a Material Adverse Effect.

                  5.7 Investment Property. (a) If such Grantor shall become
entitled to receive or shall receive any certificate (including, without
limitation, any certificate representing a dividend or a distribution in
connection with any reclassification, increase or reduction of capital or any
certificate issued in connection with any reorganization), option or rights in
respect of the Capital Stock of any Issuer, whether in addition to, in
substitution of, as a conversion of, or in exchange for, any shares of the
Pledged Stock, or otherwise in respect thereof, such Grantor shall accept the
same as the agent of the Collateral Agent and the Secured Parties, hold the same
in trust for the Collateral Agent and the Secured Parties and deliver the same
forthwith to the Collateral Agent in the exact form received, duly indorsed by
such Grantor to the Collateral Agent, if required, together with an undated
stock power covering such certificate duly executed in blank by such Grantor and
with, if the Designated Agents so request, signature guaranteed, to be held by
the Collateral Agent, subject to the terms hereof, as additional collateral
security for the Obligations. Any sums paid upon or in respect of the Investment
Property that constitutes Collateral upon the liquidation or dissolution of any
Issuer shall be paid over to the Collateral Agent to be held by it hereunder as
additional collateral security for the Obligations, and in case any distribution
of capital shall be made on or in respect of such Investment Property, or any
property shall be distributed upon or with respect to such Investment Property
pursuant to the recapitalization or reclassification of the capital of any
Issuer or pursuant to the reorganization thereof, the property so distributed
shall, unless otherwise subject to a perfected security interest in favor of the
Collateral Agent, be delivered to the Collateral Agent to be held by it
hereunder as additional collateral security for the Obligations. If any sums of
money or property so paid or distributed in respect of the Investment Property
that constitutes Collateral shall be received by such Grantor, such Grantor
shall, until such money or property is paid or delivered to the Collateral
Agent, hold such money or property in trust for the Secured Parties, segregated
from other funds of such Grantor, as additional collateral security for the
Obligations. Notwithstanding the foregoing, the Grantors shall not be required
to pay over to the Collateral Agent or deliver to the Collateral Agent as
Collateral any proceeds of any liquidation or dissolution of any Issuer, or any
distribution of capital or property in respect of any Investment Property, to
the extent that (i) such liquidation, dissolution or distribution, if treated as
a Disposition of the relevant Issuer, would be permitted by the Credit Agreement
and (ii) the proceeds thereof are applied toward prepayment of Loans and
reduction of Commitments to the extent required by the Credit Agreement.

                  (b) Such Grantor will not (i) vote to enable, or take any
other action to permit, any Issuer to issue any stock or other equity securities
of any nature or to issue any other securities convertible into or granting the
right to purchase or exchange for any stock or other

<PAGE>

equity securities of any nature of any Issuer, unless such securities are
delivered to the Collateral Agent, concurrently with the issuance thereof, to be
held by the Collateral Agent as Collateral, or (ii) without the prior written
consent of the Designated Agents, (x) sell, assign, transfer, exchange, or
otherwise dispose of, or grant any option with respect to, the Investment
Property that constitutes Collateral or Proceeds thereof (except pursuant to a
transaction expressly permitted by the Credit Agreement), (y) create, incur or
permit to exist any Lien or option in favor of, or any claim of any Person with
respect to, any of the Investment Property that constitutes Collateral or
Proceeds thereof, or any interest therein, except for the security interests
created by this Agreement and the other Liens permitted by the Credit Agreement
or (z) enter into any agreement or undertaking restricting the right or ability
of such Grantor or the Collateral Agent to sell, assign or transfer any of the
Pledged Securities or Proceeds thereof.

                  (c) In the case such Grantor is an Issuer, such Issuer agrees
that (i) it will be bound by the terms of this Agreement relating to the Pledged
Securities issued by it and will comply with such terms insofar as such terms
are applicable to it, (ii) it will notify the Administrative Agent promptly in
writing of the occurrence of any of the events described in Section 5.7(a) with
respect to the Pledged Securities issued by it and (iii) it will comply with
instructions received by it pursuant to the terms of Section 6.4(c) with respect
to the Pledged Securities issued by it.

                  (d) In the case such Grantor is an Issuer that is a
partnership or a limited liability company, such Issuer (i) confirms that none
of the terms of any equity interest issued by it provides that such equity
interest is a "security" within the meaning of Sections 8-102 and 8-103 of the
New York UCC (a "Security"), (ii) agrees that it will take no action to cause or
permit any such equity interest to become a Security, (iii) agrees that it will
not issue any certificate representing any such equity interest and (iv) agrees
that if, notwithstanding the foregoing, any such equity interest shall be or
become a Security, such Issuer will (and the Grantor that holds such equity
interest hereby instructs such Issuer to) comply with instructions originated by
the Collateral Agent without further consent by such Grantor.

                  5.8 Receivables. (a) Other than in the ordinary course of
business consistent with its past practice, such Grantor will not (i) grant any
extension of the time of payment of any Receivable, (ii) compromise or settle
any Receivable for less than the full amount thereof, (iii) release, wholly or
partially, any Person liable for the payment of any Receivable, (iv) allow any
credit or discount whatsoever on any Receivable or (v) amend, supplement or
modify any Receivable in any manner that could adversely affect the value

of each material written demand, notice or document received by it that
questions or calls into doubt the validity or enforceability of more than 5% of
the aggregate amount of the then outstanding Receivables.

         Property that constitutes Collateral:

every trademark class of goods applicable to its current line as reflected in
its current catalogs, brochures and price lists in order to maintain such
Trademark in full force free from any claim of abandonment for non-use, (ii)
maintain as in the past substantially the same quality of products and services
offered under such Trademark, (iii) use such Trademark with the appropriate
notice of registration and substantially all other notices and legends required
by applicable Requirements of Law, (iv) not knowingly adopt or use any mark

any act or knowingly omit to do any act whereby such Trademark may become

and to maintain each registration of such material Intellectual Property,
including, without limitation, filing of applications for renewal, affidavits of

                  (h) In the event that any Intellectual Property necessary for

                         SECTION 6. REMEDIAL PROVISIONS

                  6.1 Certain Matters Relating to Receivables. (a) The
Designated Agents shall have the right, at any time after the occurrence and
during the continuance of an Event of Default, to make test verifications of the
Receivables in any manner and through any medium that it reasonably considers
advisable, and each Grantor shall furnish all such assistance and information as
the Designated Agents may require in connection with such test verifications. At
any time and from time to time after the occurrence and during the continuance
of an Event of Default, upon the Designated Agents' request and at the expense
of the relevant Grantor, such Grantor shall cause independent public accountants
or others satisfactory to the Designated Agents to furnish to the Designated
Agents reports showing reconciliations, aging and test verifications of, and
trial balances for, the Receivables.

                  (b) The Collateral Agent hereby authorizes each Grantor to
collect such Grantor's Receivables, subject to the Collateral Agent's direction
and control after the occurrence and during the continuance of an Event of
Default, and the Designated Agents may curtail or terminate said authority at
any time after the occurrence and during the continuance of an Event of Default.
Each Grantor shall cause all payments in respect of Accounts to be made either
by check delivered to a Lockbox or by funds transfer to a Lockbox Account or
Control Account.

                  (c) At the Designated Agents' request at any time after the
occurrence and during the continuance of an Event of Default, each Grantor shall
deliver to the Designated Agents all original and other documents evidencing,
and relating to, the agreements and transactions which gave rise to the
Receivables, including, without limitation, all original orders, invoices and
shipping receipts.

                  6.2 Concentration Accounts. If required by the Collateral
Agent at any time after a Dominion Event has occurred, any collected funds or
other cash amounts held in any Lockbox Account or Control Account shall be
forthwith at the end of each Business Day transferred to a Concentration
Account. To the extent that Revolving Credit Loans are outstanding on any day,
amounts held in any Concentration Account on such day shall be transferred to
the Administrative Agent and applied to repay such Loans as more particularly
provided in the Control Agreement in effect with respect to such Concentration
Account.

                  6.3 Communications with Obligors; Grantors Remain Liable. (a)
if an Event of Default shall occur and be continuing, the Collateral Agent in
its own name or in the name of others may at any time communicate with obligors
under the Receivables to verify with them to the Designated Agents' satisfaction
the existence, amount and terms of any Receivables.

                  (b) Anything herein to the contrary notwithstanding, each
Grantor shall remain liable under each of the Receivables (or any agreement
giving rise thereto) to observe and perform all the conditions and obligations
to be observed and performed by it thereunder, all in

<PAGE>

                                                                              24

accordance with the terms of any agreement giving rise thereto. Neither any
Agent nor any Secured Party shall have any obligation or liability under any
Receivable (or any agreement giving rise thereto) by reason of or arising out of
this Agreement or the receipt by any Agent or any Secured Party of any payment
relating thereto, nor shall any Agent or any Secured Party be obligated in any
manner to perform any of the obligations of any Grantor under or pursuant to any
Receivable (or any agreement giving rise thereto), to make any payment, to make
any inquiry as to the nature or the sufficiency of any payment received by it or
as to the sufficiency of any performance by any party thereunder, to present or
file any claim, to take any action to enforce any performance or to collect the
payment of any amounts which may have been assigned to it or to which it may be
entitled at any time or times.

                  6.4 Pledged Stock. (a) Unless an Event of Default shall have
occurred and be continuing and the Collateral Agent shall have given notice to
the relevant Grantor of the Collateral Agent's intent to exercise its
corresponding rights pursuant to Section 6.4(b), each Grantor shall be permitted
to receive all cash dividends paid in respect of the Pledged Stock and all
payments made in respect of the Pledged Notes, in each case paid in the normal
course of business of the relevant Issuer and consistent with past practice or
otherwise in accordance with the terms of the Pledged Notes, to the extent
permitted in the Credit Agreement, and to exercise all voting and corporate
rights with respect to the Pledged Securities; provided, however, that no vote
shall be cast or corporate right exercised or other action taken in a manner
which would impair the Collateral or which would be inconsistent with or result
in any violation of any provision of the Credit Agreement, this Agreement or any
other Loan Document.

                  (b) If an Event of Default shall occur and be continuing and
the Collateral Agent (in consultation with the Administrative Agent) shall give
notice of its intent to exercise such rights to the relevant Grantor or
Grantors, (i) the Collateral Agent shall have the right to receive any and all
cash dividends, payments or other Proceeds paid in respect of the Pledged
Securities and make application thereof to the Obligations in the order set
forth in Section 6.6, and (ii) any or all of the Pledged Securities shall be
registered in the name of the Collateral Agent or its nominee, and the
Collateral Agent or its nominee may thereafter exercise (x) all voting,
corporate and other rights pertaining to such Pledged Securities at any meeting
of shareholders of the relevant Issuer or Issuers or otherwise and (y) any and
all rights of conversion, exchange and subscription and any other rights,
privileges or options pertaining to such Pledged Securities as if it were the
absolute owner thereof (including, without limitation, the right to exchange at
its discretion any and all of the Pledged Securities upon the merger,
consolidation, reorganization, recapitalization or other fundamental change in
the corporate structure of any Issuer, or upon the exercise by any Grantor or
the Collateral Agent of any right, privilege or option pertaining to such
Pledged Securities, and in connection therewith, the right to deposit and
deliver any and all of the Pledged Securities with any committee, depositary,
transfer agent, registrar or other designated agency upon such terms and
conditions as the Designated Agents may determine), all without liability except
to account for property actually received by it, but the Collateral Agent shall
have no duty to any Grantor to exercise any such right, privilege or option and
shall not be responsible for any failure to do so or delay in so doing.

                  (c) Each Grantor hereby authorizes and instructs each Issuer
of any Pledged Securities pledged by such Grantor hereunder to (i) comply with
any instruction received by it from the Collateral Agent in writing that (x)
states that an Event of Default has occurred and is

<PAGE>

                                                                              25

continuing and (y) is otherwise in accordance with the terms of this Agreement,
without any other or further instructions from such Grantor, and each Grantor
agrees that each Issuer shall be fully protected in so complying, and (ii)
unless otherwise expressly permitted hereby, pay any dividends or other payments
with respect to the Pledged Securities directly to the Collateral Agent.

                  6.5 Proceeds to be Turned Over To Collateral Agent. In
addition to the rights of the Designated Agents and the Secured Parties
specified in Section 6.1 with respect to payments of Receivables, if an Event of
Default shall occur and be continuing, all Proceeds of Collateral other than
Accounts received by any Grantor consisting of cash, checks and Instruments
shall be held by such Grantor in trust for the Collateral Agent and the Secured
Parties, segregated from other funds of such Grantor, and shall, forthwith upon
receipt by such Grantor, be turned over to the Collateral Agent in the exact
form received by such Grantor (duly indorsed by such Grantor to the Collateral
Agent, if required). All Proceeds received by the Collateral Agent hereunder
shall be held by the Collateral Agent in a Control Account maintained under its
sole dominion and control. All Proceeds while held by the Collateral Agent in a
Control Account (or by such Grantor in trust for the Collateral Agent and the
Secured Parties) shall continue to be held as collateral security for all the
Obligations and shall not constitute payment thereof until applied as provided
in Section 6.6.

                  6.6 Application of Proceeds. At such intervals as may be
agreed upon by the Borrower and the Designated Agents, or, if an Event of
Default shall have occurred and be continuing, at any time at the Designated
Agents' election, the Collateral Agent shall apply all or any part of Proceeds
constituting Collateral, whether or not held in any Control Account, and any

                           outstanding Loans and Reimbursement Obligations,
                           ratably among the holders of such Obligations in
                           accordance with the amounts of such Obligations then
                           held by each thereof;

                  (z)      FOURTH, in an amount equal to the aggregate undrawn
                           amount of all outstanding Letters of Credit, to be
                           deposited in a collateral account under the sole
                           dominion and control of the Collateral Agent to be
                           held as collateral for such obligations;

                  (aa)     FIFTH, to repay Borrower Bank Product Obligations and

<PAGE>

                                                                              28

                  (bb)     SIXTH, to pay any other Revolving Credit Facility
                           Obligations and Term Loan Facility Obligations not
                           described above; and

                  (cc)     SEVENTH, to be delivered to the Borrower or as
                           otherwise may be required by applicable law.

                  6.7 Code and Other Remedies. If an Event of Default shall
occur and be continuing, the Agents, on behalf of the Secured Parties, may
exercise, in addition to all other rights and remedies granted to them in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Obligations, all rights and remedies of a secured party under
the New York UCC or any other applicable law. Without limiting the generality of
the foregoing, the Collateral Agent, without demand of performance or other
demand, presentment, protest, advertisement or notice of any kind (except notice
pursuant to Section 6.4(b) and any notice required by law referred to below) to
or upon any Grantor or any other Person (all and each of which demands,
defenses, advertisements and notices are hereby waived), may in such
circumstances forthwith collect, receive, appropriate and realize upon the
Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give
option or options to purchase, or otherwise dispose of and deliver the
Collateral or any part thereof (or contract to do any of the foregoing), in one
or more parcels at public or private sale or sales, at any exchange, broker's
board or office of the Collateral Agent or any Secured Party or elsewhere upon
such terms and conditions as it may deem advisable and at such prices as it may
deem best, for cash or on credit or for future delivery without assumption of
any credit risk. Any Agent or any Secured Party shall have the right upon any
such public sale or sales, and, to the extent permitted by law, upon any such
private sale or sales, to purchase the whole or any part of the Collateral so
sold, free of any right or equity of redemption in any Grantor, which right or
equity is hereby waived and released. Each Grantor further agrees, at the
Collateral Agent's request, to assemble the Collateral and make it available to
the Collateral Agent at places which the Collateral Agent shall reasonably
select, whether at such Grantor's premises or elsewhere. The Collateral Agent
shall apply the net proceeds of any action taken by it pursuant to this Section
6.7 with respect to any Grantor's Collateral, after deducting all reasonable
costs and expenses of every kind incurred in connection therewith or incidental
to the care or safekeeping of any of the Collateral of such Grantor or in any
way relating to the Collateral of such Grantor or the rights of the Agents and
the Secured Parties hereunder with respect thereto, including, without
limitation, reasonable attorneys' fees and disbursements, to the payment in
whole or in part of the Obligations of such Grantor, in the order specified in
Section 6.6, and only after such application and after the payment by the
Collateral Agent of any other amount required by any provision of law,
including, without limitation, Section 9-615(a)(3) of the New York UCC, need the
Collateral Agent account for the surplus, if any, to any Grantor. To the extent
permitted by applicable law, each Grantor waives all claims, damages and demands
it may acquire against any Agent or any Secured Party arising out of the
exercise by them of any rights hereunder, to the extent such exercise does not
constitute gross negligence or willful misconduct. If any notice of a proposed
sale or other disposition of Collateral shall be required by law, such notice
shall be deemed reasonable and proper if given at least 10 days before such sale
or other disposition.

                  6.8 Registration Rights. (a) If the Designated Agents shall
determine to exercise the right to sell any or all of the Pledged Stock pursuant
to Section 6.7, and if in the opinion of the Designated Agents it is necessary
or advisable to have the Pledged Stock, or that portion

<PAGE>

                                                                              29

thereof to be sold, registered under the provisions of the Securities Act, the
relevant Grantor will cause the Issuer thereof to (i) execute and deliver, and
cause the directors and officers of such Issuer to execute and deliver, all such
instruments and documents, and do or cause to be done all such other acts as may
be, in the opinion of the Designated Agents, necessary or advisable to register
the Pledged Stock, or that portion thereof to be sold, under the provisions of
the Securities Act, (ii) use its best efforts to cause the registration
statement relating thereto to become effective and to remain effective for a
period of one year from the date of the first public offering of the Pledged
Stock, or that portion thereof to be sold, and (iii) make all amendments thereto
and/or to the related prospectus which, in the opinion of the Designated Agents,
are necessary or advisable, all in conformity with the requirements of the
Securities Act and the rules and regulations of the Securities and Exchange
Commission applicable thereto. Each Grantor agrees to cause such Issuer to
comply with the provisions of the securities or "Blue Sky" laws of any and all
jurisdictions which the Designated Agents shall designate and to make available
to its security holders, as soon as practicable, an earnings statement (which
need not be audited) which will satisfy the provisions of Section 11(a) of the
Securities Act.

                  (b) Each Grantor recognizes that the Collateral Agent may be
unable to effect a public sale of any or all the Pledged Stock, by reason of
certain prohibitions contained in the Securities Act and applicable state
securities laws or otherwise, and may be compelled to resort to one or more
private sales thereof to a restricted group of purchasers which will be obliged
to agree, among other things, to acquire such securities for their own account
for investment and not with a view to the distribution or resale thereof. Each
Grantor acknowledges and agrees that any such private sale may result in prices
and other terms less favorable than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner. The Designated
Agents shall be under no obligation to delay a sale of any of the Pledged Stock
for the period of time necessary to permit the Issuer thereof to register such
securities for public sale under the Securities Act, or under applicable state
securities laws, even if such Issuer would agree to do so.

                  (c) Each Grantor agrees to use its best efforts to do or cause
to be done all such other acts as may be necessary to make such sale or sales of
all or any portion of the Pledged Stock pursuant to this Section 6.8 valid and
binding and in compliance with any and all other applicable Requirements of Law.
Each Grantor further agrees that a breach of any of the covenants contained in
this Section 6.8 will cause irreparable injury to the Designated Agents and the
Secured Parties, that the Designated Agents and the Secured Parties have no
adequate remedy at law in respect of such breach and, as a consequence, that
each and every covenant contained in this Section 6.8 shall be specifically
enforceable against such Grantor, and such Grantor hereby waives and agrees not
to assert any defenses against an action for specific performance of such
covenants except for a defense that no Event of Default has occurred under the
Credit Agreement.

                                                                              30

                  6.9 Deficiency. Each Grantor shall remain liable for any
deficiency if the proceeds of any sale or other disposition of the Collateral
are insufficient to pay its Obligations and the fees and disbursements of any
attorneys employed by the Designated Agents or any Secured Party to collect such
deficiency.

                        SECTION 7. THE COLLATERAL AGENT

                  7.1 Collateral Agent's Appointment as Attorney-in-Fact, etc.
(a) Each Grantor hereby irrevocably constitutes and appoints the Collateral
Agent and any officer or agent thereof, with full power of substitution, as its
true and lawful attorney-in-fact with full irrevocable power and authority in
the place and stead of such Grantor and in the name of such Grantor or in its
own name, for the purpose of carrying out the terms of this Agreement, to take
any and all appropriate action and to execute any and all documents and
instruments which may be necessary or desirable to accomplish the purposes of
this Agreement, and, without limiting the generality of the foregoing, each
Grantor hereby gives the Collateral Agent the power and right, on behalf of such
Grantor, without notice to or assent by such Grantor, to do any or all of the
following:

                  (i)      in the name of such Grantor or its own name, or
         otherwise, take possession of and indorse and collect any checks,
         drafts, notes, acceptances or other instruments for the payment of
         moneys due under any Receivable or with respect to any other Collateral
         and file any claim or take any other action or proceeding in any court
         of law or equity or otherwise deemed appropriate by the Designated
         Agents for the purpose of collecting any and all such moneys due under
         any Receivable or with respect to any other Collateral whenever
         payable;

                  (ii)     in the case of any material Intellectual Property
         that constitutes Collateral, execute and deliver, and have recorded,
         any and all agreements, instruments, documents and papers as the
         Designated Agents may request to evidence the Collateral Agent's and
         the Secured Parties' security interest in such Intellectual Property
         and the goodwill and general intangibles of such Grantor relating
         thereto or represented thereby;

                  (iii)    pay or discharge taxes and Liens levied or placed on
         or threatened against the Collateral, effect any repairs or any
         insurance called for by the terms of this Agreement and pay all or any
         part of the premiums therefor and the costs thereof;

                  (iv)     execute, in connection with any sale provided for in
         Section 6.7 or 6.8, any endorsements, assignments or other instruments
         of conveyance or transfer with respect to the Collateral;

                  (v)      (1) direct any party liable for any payment under any
         of the Collateral to make payment of any and all moneys due or to
         become due thereunder directly to the Collateral Agent or as the
         Designated Agents shall direct; (2) ask or demand for, collect, and
         receive payment of and receipt for, any and all moneys, claims and
         other amounts due or to become due at any time in respect of or arising
         out of any Collateral; (3) sign and indorse any invoices, freight or
         express bills, bills of lading, storage or warehouse receipts, drafts
         against debtors, assignments, verifications, notices and other
         documents in

<PAGE>

                                                                              31

         connection with any of the Collateral; (4) commence and prosecute any
         suits, actions or proceedings at law or in equity in any court of
         competent jurisdiction to collect the Collateral or any portion thereof
         and to enforce any other right in respect of any Collateral; (5) defend
         any suit, action or proceeding brought against such Grantor with
         respect to any Collateral; (6) settle, compromise or adjust any such
         suit, action or proceeding and, in connection therewith, give such
         discharges or releases as the Designated Agents may deem appropriate;
         (7) assign any Copyright, Patent or Trademark that constitutes
         Collateral (along with the goodwill of the business to which any such
         Copyright, Patent or Trademark pertains), throughout the world for such
         term or terms, on such conditions, and in such manner, as the
         Designated Agents shall in their sole discretion determine; and (8)
         generally, sell, transfer, pledge and make any agreement with respect
         to or otherwise deal with any of the Collateral as fully and completely
         as though the Collateral Agent were the absolute owner thereof for all
         purposes, and do, at the Designated Agents' option and such Grantor's
         expense, at any time, or from time to time, all acts and things which
         the Designated Agents deem necessary to protect, preserve or realize
         upon the Collateral and the Collateral Agent's and the Secured Parties'
         security interests therein and to effect the intent of this Agreement,
         all as fully and effectively as such Grantor might do; and

                  (vi)     license or sublicense whether on an exclusive or
         non-exclusive basis, any Intellectual Property that constitutes
         Collateral for such term and on such conditions and in such manner as
         the Designated Agents shall in their sole judgment determine.

                  Anything in this Section 7.1 (a) to the contrary
notwithstanding, the Collateral Agent agrees that it will not exercise any
rights under the power of attorney provided for in this Section 7.1(a) unless an
Event of Default shall have occurred and be continuing.

                  (b) If any Grantor fails to perform or comply with any of its
agreements contained herein, the Collateral Agent, at its option (in
consultation with the Administrative Agent), but without any obligation so to
do, may perform or comply, or otherwise cause performance or compliance, with
such agreement.

                  (c) The expenses of each Designated Agent incurred in
connection with actions undertaken as provided in this Section 7.1, together
with interest thereon at a rate per annum equal to the rate per annum at which
interest would then be payable on past due Revolving Credit Loans that are Base
Rate Loans under the Credit Agreement, from the date of payment by such
Designated Agent to the date reimbursed by the relevant Grantor, shall be
payable by such Grantor to such Designated Agent on demand.

                  (d) Each Grantor hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof. All powers, authorizations and
agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released.

                  7.2 Duty of Collateral Agent. The Collateral Agent's sole duty
with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the New York UCC or
otherwise, shall be to deal with it in the same manner as the Collateral Agent
deals with similar property for its own account. Neither the Collateral Agent,

<PAGE>

                                                                              32

any Secured Party nor any of their respective officers, directors, employees or
agents shall be liable for failure to demand, collect or realize upon any of the
Collateral or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Collateral upon the request of any Grantor or any
other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof. The powers conferred on the Designated Agents
and the Secured Parties hereunder are solely to protect the Collateral Agent's
and the Secured Parties' interests in the Collateral and shall not impose any
duty upon the Designated Agents or any Secured Party to exercise any such
powers. The Collateral Agent and the Secured Parties shall be accountable only
for amounts that they actually receive as a result of the exercise of such
powers, and neither they nor any of their officers, directors, employees or
agents shall be responsible to any Grantor for any act or failure to act
hereunder, except for their own gross negligence or willful misconduct.

                  7.3 Execution of Financing Statements. . Pursuant to any
applicable law, each Grantor authorizes each of the Designated Agents to file or
record financing statements and other filing or recording documents or
instruments with respect to the Collateral without the signature of such Grantor
in such form and in such offices as the Designated Agents determine appropriate
to perfect the security interests of the Collateral Agent under this Agreement.
Each Grantor authorizes the Administrative Agent to use the collateral
description "all personal property" in any such financing statements. Each
Grantor hereby ratifies and authorizes the filing by the Collateral Agent of any
financing statement with respect to the Collateral made prior to the date
hereof.

                  7.4 Authority of Collateral Agent. Each Grantor acknowledges
that the rights and responsibilities of the Collateral Agent under this
Agreement with respect to any action taken by the Collateral Agent or the
exercise or non-exercise by the Collateral Agent of any option, voting right,
request, judgment or other right or remedy provided for herein or resulting or
arising out of this Agreement shall, as between the Collateral Agent and the
Secured Parties, be governed by the Credit Agreement and by such other
agreements with respect thereto as may exist from time to time among them, but,
as between the Collateral Agent and the Grantors, the Collateral Agent shall be
conclusively presumed to be acting as agent for the Secured Parties with full
and valid authority so to act or refrain from acting, and no Grantor shall be
under any obligation, or entitlement, to make any inquiry respecting such
authority. Notwithstanding any other provision herein or in any Loan Document,
the only duty or responsibility of the Collateral Agent to any Qualified
Counterparty under this Agreement is the duty to remit to such Qualified
Counterparty any amounts to which it is entitled pursuant to Section 6.6.

                            SECTION 8. MISCELLANEOUS

                  8.1 Amendments in Writing. None of the terms or provisions of
this Agreement may be waived, amended, supplemented or otherwise modified except
in accordance with Section 10.1 of the Credit Agreement. No consent of any
Qualified Counterparty shall be required for any waiver, amendment, supplement
or other modification to this Agreement.

<PAGE>

                                                                              33

                  8.2 Notices. All notices, requests and demands to or upon the
Collateral Agent, the Administrative Agent or any Grantor hereunder shall be
effected in the manner provided for in Section 10.2 of the Credit Agreement;
provided that any such notice, request or demand to or upon any Guarantor shall
be addressed to such Guarantor at its notice address set forth on Schedule 1.

                  8.3 No Waiver by Course of Conduct; Cumulative Remedies.
Neither the Collateral Agent, the Administrative Agent nor any Secured Party
shall by any act (except by a written instrument pursuant to Section 8.1),
delay, indulgence, omission or otherwise be deemed to have waived any right or
remedy hereunder or to have acquiesced in any Default or Event of Default. No
failure to exercise, nor any delay in exercising, on the part of the Collateral
Agent, the Administrative Agent or any Secured Party, any right, power or
privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
A waiver by the Collateral Agent, the Administrative Agent or any Secured Party
of any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which the Collateral Agent, the Administrative Agent
or such Secured Party would otherwise have on any future occasion. The rights
and remedies herein provided are cumulative, may be exercised singly or
concurrently and are not exclusive of any other rights or remedies provided by
law.

                  8.4 Enforcement Expenses; Indemnification. (a) Each Guarantor
agrees to pay, or reimburse each Secured Party and each Designated Agent for,
all its costs and expenses incurred in collecting against such Guarantor under
the guarantee contained in Section 2 or otherwise enforcing or preserving any
rights under this Agreement and the other Loan Documents to which such Guarantor
is a party, including, without limitation, the fees and disbursements of counsel
(including the allocated fees and expenses of in-house counsel) to each Secured
Party and of counsel to each Designated Agent.

                  (b) Each Guarantor agrees to pay, and to save the Designated
Agents and the Secured Parties harmless from, any and all liabilities with
respect to, or resulting from any delay in paying, any and all stamp, excise,
sales or other taxes which may be payable or determined to be payable with
respect to any of the Collateral or in connection with any of the transactions
contemplated by this Agreement.

                  (c) Each Guarantor agrees to pay, and to save the Designated
Agents and the Secured Parties harmless from, any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever with respect to the
execution, delivery, enforcement, performance and administration of this
Agreement to the extent the Borrower would be required to do so pursuant to
Section 10.5 of the Credit Agreement.

                  (d) The agreements in this Section shall survive repayment of
the Obligations and all other amounts payable under the Credit Agreement and the
other Loan Documents.

                  8.5 Successors and Assigns. This Agreement shall be binding
upon the successors and assigns of each Grantor and shall inure to the benefit
of the Collateral Agent, the Administrative Agent and the Secured Parties and
their successors and assigns; provided that no

<PAGE>

                                                                              34

Grantor may assign, transfer or delegate any of its rights or obligations under
this Agreement without the prior written consent of the Designated Agents.

                  8.6 Set-Off. Each Grantor hereby irrevocably authorizes each
Designated Agent and each Secured Party at any time and from time to time while
an Event of Default pursuant to Section 8(a) of the Credit Agreement shall have
occurred and be continuing, without notice to such Grantor or any other Grantor,
any such notice being expressly waived by each Grantor, to set-off and
appropriate and apply any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by such Designated
Agent or such Secured Party to or for the credit or the account of such Grantor,
or any part thereof in such amounts as such Designated Agent or such Secured
Party may elect, against and on account of the obligations and liabilities of
such Grantor to such Designated Agent or such Secured Party hereunder and claims
of every nature and description of such Designated Agent or such Secured Party
against such Grantor, in any currency, whether arising hereunder, under the
Credit Agreement, any other Loan Document or otherwise, as such Designated Agent
or such Secured Party may elect, whether or not such Designated Agent or any
Secured Party has made any demand for payment and although such obligations,
liabilities and claims may be contingent or unmatured. Each Designated Agent and
each Secured Party shall notify such Grantor promptly of any such set-off and
the application made by such Designated Agent or such Secured Party of the
proceeds thereof, provided that the failure to give such notice shall not affect
the validity of such set-off and application. The rights of each Designated
Agent and each Secured Party under this Section are in addition to other rights
and remedies (including, without limitation, other rights of set-off) which such
Designated Agent or such Secured Party may have.

                  8.7 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by telecopy), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument.

                  8.8 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  8.9 Section Headings. The Section headings used in this
Agreement are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation hereof.

                  8.10 Integration. This Agreement and the other Loan Documents
represent the agreement of the Grantors, the Designated Agents and the Secured
Parties with respect to the subject matter hereof and thereof, and there are no
promises, undertakings, representations or warranties by the Designated Agents
or any Secured Party relative to subject matter hereof and thereof not expressly
set forth or referred to herein or in the other Loan Documents.

                  8.11 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  8.12 Submission To Jurisdiction; Waivers. Each Grantor hereby
irrevocably and unconditionally:

                  (a) submits for itself and its Property in any legal action or
proceeding relating to this Agreement and the other Loan Documents to which it
is a party, or for recognition and enforcement of any judgment in respect
thereof, to the non-exclusive general jurisdiction of the Courts of the State of
New York, the courts of the United States of America for the Southern District
of New York, and appellate courts from any thereof;

                  (b) consents that any such action or proceeding may be brought
in such courts and waives any objection that it may now or hereafter have to the
venue of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

                  (c) agrees that service of process in any such action or

                  (a) it has been advised by counsel in the negotiation,
execution and delivery of this Agreement and the other Loan Documents to which

                  (b) neither the Collateral Agent, the Administrative Agent nor
any other Secured Party has any fiduciary relationship with or duty to any

a Grantor for all purposes of this Agreement upon execution and delivery by such
Subsidiary of an Assumption Agreement in the form of Annex 1 hereto.

                  8.15 Releases. (a) At such time as the Loans, the
Reimbursement Obligations and the other Obligations (other than Borrower Bank
Product Obligations, Guarantor Bank Product Obligations, the Borrower Guarantee
Obligations and the obligations of the Guarantors in respect of such Borrower
Guarantee Obligations that arise under Section 2.1(a)(i)) shall have been paid
in full, the Commitments have been terminated and no Letters of Credit shall be
outstanding, the Collateral shall be released from the Liens created hereby, and
this Agreement and all obligations (other than the provisions of this Agreement
and the obligations hereunder that are herein expressly stated to survive such
termination) of the Designated Agents and each Grantor hereunder shall
terminate, all without delivery of any instrument or performance of any act by
any party, and all rights to the Collateral shall revert to the Grantors. At the
request and sole expense of any Grantor following any such termination, the
Collateral Agent shall (without notice to, or vote or consent of, any Lender, or
any party to any Bank Product) take such actions as shall be required to release
its security interest in all Collateral, and the Administrative Agent shall
(without notice to, or vote or consent of, any Lender, or any party to any Bank

release of guarantee obligations shall be deemed subject to the provision that
such guarantee obligations shall be reinstated if after such release any portion
of any payment in respect of the Obligations guaranteed thereby shall be
rescinded or must otherwise be restored or returned upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Borrower or any
Guarantor, or upon or as a result of the appointment of a receiver, intervenor
or conservator of, or trustee or similar officer for, the Borrower or any
Guarantor or any substantial part of its property, or otherwise, all as though
such payment had not been made

                  (b) If any of the Collateral shall be sold, transferred or
otherwise disposed of by any Grantor in a transaction permitted by the Credit
Agreement, then the Collateral Agent, at the request and sole expense of such
Grantor, shall (without notice to, or vote or consent of, any Lender, or any
party to any Bank Product) take such actions as shall be required to release its
security interest in any Collateral being Disposed of in such Disposition
(including, in the case of a Disposition of any Person, all Capital Stock of
such Person and all Property of such Person), and the Administrative Agent shall
(without notice to, or vote or consent of, any Lender, or any party to any Bank
Product) take such actions as shall be required to release any guarantee and
other obligations under any Loan Document of any Person being Disposed of in
such Disposition; provided that the Borrower shall have delivered to the
Designated Agents, at least ten Business Days prior to the date of the proposed
release of any Guarantor in connection with the Disposition of all of its
Capital Stock, a written request for release identifying the relevant Guarantor
and the terms of the sale or other disposition in reasonable detail, including
the price thereof and any expenses in connection therewith, together with a
certification by the Borrower stating that such transaction is in compliance
with the Credit Agreement and the other Loan Documents. At such time as the Term
Loans shall have been repaid in full, the Existing Convertible Notes shall have
been repaid in full and the Consolidated Liquidity shall be not less than an
amount to be agreed upon by the Designated Agents at such time, promptly upon
the request of the Borrower, the Eligible Rental Equipment shall be removed from
the Borrowing

interest in any of its assets; that the Collateral does not include any assets
