                (b) Payment of Fees. All fees payable hereunder shall be paid on
the dates due, in immediately available funds, to the Administrative Agent. Fees
paid shall not be refundable under any circumstances.

                Payments; Pro Rata Treatment; Sharing of Set-offs

     Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.
                  -----------------------------------------------------------

                (a) Payments. The Borrowers shall make each payment required to
be made by them hereunder (whether of principal, interest or fees, or of amounts
payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to
12:00 noon, New York City time, on the date when due, in immediately available
funds, without defense, deduction, recoupment, set-off or counterclaim. Any
amounts received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices specified in Section
12.01, as expressly provided herein and except that payments pursuant to Section
5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the
Persons entitled thereto. The Administrative Agent shall distribute any such
payments received by it for the account of any other Person to the appropriate
recipient promptly following receipt thereof. If any payment hereunder shall be
due on a day that is not a Business Day, except as otherwise set forth herein
the date for payment shall be extended to the next succeeding Business Day, and,
in the case of any payment accruing interest, interest thereon shall be payable
for the period of such extension. All payments hereunder shall be made in
dollars.

                (b) Application of Insufficient Payments. If at any time
insufficient funds are received by and available to the Administrative Agent to
pay fully all amounts of principal, interest and fees then due hereunder, such
funds shall be applied (i) first, towards payment of interest and fees then due
hereunder, ratably among the parties entitled thereto in accordance with the
amounts of interest and fees then due to such parties, and (ii) second, towards
payment of principal then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of principal then due to such parties.

                (c) Sharing of Payments by Lenders. If any Lender shall, by
exercising any right of set-off or counterclaim or otherwise, obtain payment in
respect of any principal of or interest on its Loan resulting in such Lender
receiving payment of a greater proportion of the aggregate amount of its Loan
and accrued interest thereon than the proportion received by any other Lender,
then the Lender receiving such greater proportion shall purchase (for cash at
face value) participations in the Loans of other Lenders to the extent necessary
so that the benefit of all such payments shall be shared by the Lenders ratably
in accordance with their Percentage Shares of the aggregate amount of principal
of and accrued interest on their respective Loans; provided that (i) if any such
participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase
price restored to the extent of such recovery, without interest, and (ii) the
provisions of this Section 4.01(c) shall not be construed to apply to any
payment made by the Borrowers pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in its Loan to any assignee or
participant, other than to the Borrowers or any Subsidiary or Affiliate thereof
(as to which the provisions of this Section 4.01(c) shall apply). The Borrowers
consent to the foregoing and agree, to the extent it may effectively do so under
applicable law, that any Lender acquiring a participation pursuant to the
foregoing arrangements may exercise against each of the Borrowers rights of
set-off and counterclaim with respect to such participation as fully as if such
Lender were a direct creditor of such Borrower in the amount of such
participation.

     Section 4.02 Presumption of Payment by the Borrowers. Unless the
Administrative Agent shall have received notice from the Borrowers prior to the
date on which any payment is due to the Administrative Agent for the account of
the Lenders that the Borrowers will not make such payment, the Administrative
Agent may assume that the Borrowers have made such payment on such date in
accordance herewith and may, in reliance upon such assumption, distribute to the
Lenders the amount due. In such event, if the Borrowers have not in fact made
such payment, then each of the Lenders severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such
Lender with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the
Administrative Agent, at the greater of the Federal Funds Effective Rate and a
rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation.

     Section 4.03 Certain Deductions by the Administrative Agent. If any Lender
shall fail to make any payment required to be made by it pursuant to Section
4.02, then the Administrative Agent may, in its discretion (notwithstanding any
contrary provision hereof), apply any amounts thereafter received by the
Administrative Agent for the account of such Lender to satisfy such Lender's
obligations under such Section until all such unsatisfied obligations are fully
paid.

     Section 4.04 Disposition of Proceeds. The Security Instruments contain an
assignment by each of the Borrowers and/or the Guarantors unto and in favor of
the Administrative Agent for the benefit of the Lenders of all of each
Borrower's or each

                                       25
<PAGE>

Guarantor's interest in and to production and all proceeds attributable thereto
which may be produced from or allocated to the Mortgaged Property. The Security
Instruments further provide in general for the application of such proceeds to
the satisfaction of the Indebtedness and other obligations described therein and
secured thereby. Notwithstanding the assignment contained in such Security
Instruments, unless an Event of Default has occurred and is continuing, (a) the
Administrative Agent and the Lenders agree that they will neither notify the
purchaser or purchasers of such production nor take any other action to cause
such proceeds to be remitted to the Administrative Agent or the Lenders, but the
Lenders will instead permit such proceeds to be paid to the Borrowers and their
Subsidiaries and (b) the Lenders hereby authorize the Administrative Agent to
take such actions as may be necessary to cause such proceeds to be paid to the
Borrowers and/or such Subsidiaries.

           Increased Costs; Break Funding Payments; Taxes; Illegality

     Section 5.01 Increased Costs.
                  ---------------

                (a) Changes in Law. If any Change in Law shall:
                    --------------

                        (i) impose, modify or deem applicable any reserve,
special deposit or similar requirement against assets of, deposits with or for
the account of, or credit extended by, any Lender (except any such reserve
requirement reflected in the Adjusted LIBO Rate); or

                        (ii) impose on any Lender or the London interbank market
any other condition affecting this Agreement or Loans of such Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Loan or to reduce the amount of any sum
received or receivable by such Lender (whether of principal, interest or
otherwise), then the Borrowers will pay to such Lender such additional amount or
amounts as will compensate such Lender for such additional costs incurred or
reduction suffered.

                (b) Capital Requirements. If any Lender determines that any
Change in Law regarding capital requirements has or would have the effect of
reducing the rate of return on such Lender's capital or on the capital of such
Lender's holding company, if any, as a consequence of this Agreement or the Loan
made by such Lender, to a level below that which such Lender or the or such
Lender's holding company could have achieved but for such Change in Law (taking
into consideration such Lender's policies and the policies of such Lender's
holding company with respect to capital adequacy), then from time to time the
Borrowers will pay to such Lender such additional amount or amounts as will
compensate such Lender or such Lender's holding company for any such reduction
suffered.

                (c) Certificates. A certificate of a Lender setting forth the
amount or amounts necessary to compensate such Lender or its holding company, as
the case may be, as specified in Section 5.01(a) or (b) shall be delivered to
the Borrowers and shall be

                                       26
<PAGE>

conclusive absent manifest error. The Borrowers shall pay such Lender the amount
shown as due on any such certificate within 10 Business Days after receipt
thereof.

                (d) Effect of Failure or Delay in Requesting Compensation.
Failure or delay on the part of any Lender to demand compensation pursuant to
this Section 5.01 shall not constitute a waiver of such Lender's right to demand
such compensation; provided that the Borrowers shall not be required to
compensate a Lender pursuant to this Section 5.01 for any increased costs or
reductions incurred more than 180 days prior to the date that such Lender
notifies the Borrowers of the Change in Law giving rise to such increased costs
or reductions and of such Lender's intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 180-day period referred to above shall be
extended to include the period of retroactive effect thereof.

     Section 5.02 Break Funding Payments. In the event of (a) the payment of any
principal of any Loan other than on the last day of an Interest Period
applicable thereto (including as a result of an Event of Default), (b) the
failure to prepay any Loan on the date specified in any notice delivered
pursuant hereto, or (c) the assignment of any Loan other than on the last day of
the Interest Period applicable thereto as a result of a request by the Borrowers
pursuant to Section 5.04(b), then, in any such event, the Borrowers shall
compensate each Lender for the loss, cost and expense attributable to such
event. Such loss, cost or expense to any Lender shall be deemed to include an
amount determined by such Lender to be the excess, if any, of (i) the amount of
interest which would have accrued on the principal amount of such Loan had such
event not occurred, at the Adjusted LIBO Rate that would have been applicable to
such Loan, for the period from the date of such event to the last day of the
then current Interest Period therefor (or, in the case of a failure to borrow,
convert or continue, for the period that would have been the Interest Period for
such Loan), over (ii) the amount of interest which would accrue on such
principal amount for such period at the interest rate which such Lender would
bid were it to bid, at the commencement of such period, for dollar deposits of a
comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender
is entitled to receive pursuant to this Section 5.02 shall be delivered to the
Borrowers and shall be conclusive absent manifest error. The Borrowers shall pay
such Lender the amount shown as due on any such certificate within 10 Business
Days after receipt thereof.

     Section 5.03 Taxes.
                  -----

                (a) Payments Free of Taxes. Any and all payments by or on
account of any obligation of the Borrowers or any Guarantor under any Loan
Document shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if the Borrowers or any
Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section 5.03), the Administrative Agent

                                       27
<PAGE>

or any Lender (as the case may be) receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Borrowers or such
Guarantor shall make such deductions and (iii) the Borrowers or such Guarantor
shall pay the full amount deducted to the relevant Governmental Authority in
accordance with applicable law.

                (b) Payment of Other Taxes by the Borrowers. The Borrowers shall
pay any Other Taxes to the relevant Governmental Authority in accordance with
applicable law.

                (c) Indemnification by the Borrowers. The Borrowers shall
indemnify the Administrative Agent and each Lender, within 10 Business Days
after written demand therefor, for the full amount of any Indemnified Taxes or
Other Taxes paid by the Administrative Agent or such Lender on or with respect
to any payment by or on account of any obligation of the Borrowers hereunder
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 5.03) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate of the
Administrative Agent or a Lender as to the amount of such payment or liability
under this Section 5.03 shall be delivered to the Borrowers and shall be
conclusive absent manifest error.

                (d) Evidence of Payments. As soon as practicable after any
payment of Indemnified Taxes or Other Taxes by the Borrowers or a Guarantor to a
Governmental Authority, the Borrowers shall deliver to the Administrative Agent
the original or a certified copy of a receipt issued by such Governmental
Authority evidencing such payment, a copy of the return reporting such payment
or other evidence of such payment reasonably satisfactory to the Administrative
Agent.

                (e) Foreign Lenders. Any Foreign Lender that is entitled to an
exemption from or reduction of withholding tax under the law of the jurisdiction
in which either of the Borrowers is located, or any treaty to which such
jurisdiction is a party, with respect to payments under this Agreement or any
other Loan Document shall deliver to such Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such
properly completed and executed documentation prescribed by applicable law or
reasonably requested by such Borrower as will permit such payments to be made
without withholding or at a reduced rate.

     Section 5.04  Mitigation Obligations; Replacement of Lenders.
                   ----------------------------------------------

                (a) Designation of Different Lending Office. If any Lender
requests compensation under Section 5.01, or if the Borrowers are required to
pay any additional amount to any Lender or any Governmental Authority for the
account of any Lender pursuant to Section 5.03, then such Lender shall use
reasonable efforts to designate a different lending office for funding or
booking its Loan hereunder or to assign its rights and obligations hereunder to
another of its offices, branches or affiliates, if, in the judgment of such
Lender, such designation or assignment (i) would eliminate or reduce

                                       28
<PAGE>

amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in
the future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The Borrowers
hereby agree to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

                (b) Replacement of Lenders. If any Lender requests compensation
under Section 5.01, or if the Borrowers are required to pay any additional
amount to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 5.03, or if any Lender defaults in its obligation to fund
its Loan hereunder, or if any Lender is prevented from making its Loan under
Section 5.05, or if any Lender declines to vote in favor of an amendment, waiver
or other modification recommended by the Administrative Agent, then the
Borrowers may, at their sole expense and effort, upon notice to such Lender and
the Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 12.04(b)), all its interests, rights and obligations under this
Agreement to an assignee that shall assume such obligations (which assignee may
be another Lender, if a Lender accepts such assignment); provided that (i) the
Borrowers shall have received the prior written consent of the Administrative
Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall
have received payment of an amount equal to the outstanding principal of its
Loan, accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrowers (in the case of all other amounts)
and (iii) in the case of any such assignment resulting from a claim for
compensation under Section 5.01 or payments required to be made pursuant to
Section 5.03, such assignment will result in a reduction in such compensation or
payments. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Borrowers to require such assignment
and delegation cease to apply.

     Section 5.05 Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
applicable lending office to honor its obligation to make or maintain its Loan
hereunder, then such Lender shall promptly notify the Borrowers and the
Administrative Agent thereof and such Lender promptly shall assign such Loan
pursuant to Section 12.04 hereunder.

                                   ARTICLE VI

     The Borrower represents and warrants to the Lenders that:

     Section 7.01 Organization; Powers. Each of the Borrowers and the
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, has all requisite corporate or
limited liability company power and authority, and has all material governmental
licenses, authorizations, consents and approvals necessary, to own its assets
and to carry on its business as now conducted, and is qualified to do business
in, and is in good standing in, every jurisdiction where such qualification is
required, except where failure to have such power, authority, licenses,
authorizations, consents, approvals and qualifications could not reasonably be
expected to have a Material Adverse Effect.

     Section 7.02 Authority; Enforceability. The Transactions are within each
Borrower's and each Guarantor's corporate or limited liability company powers
and have been duly authorized by all necessary corporate or limited liability
company and, if required, stockholder or member action (including, without
limitation, any action required to be taken by any class of directors or
managers of such Borrower, whether interested or disinterested, in order to

environment.

                (f) to the extent applicable, all Property of each Borrower and

Agreement.

with all Governmental Requirements applicable to it or its Property and all
agreements and other instruments binding upon it or its Property, and possesses
all licenses, permits, franchises, exemptions, approvals and other governmental

Effect.

                (b) Neither of the Borrowers and no Subsidiary is in default nor
has any event or circumstance occurred which, but for the expiration of any
applicable grace period or the giving of notice, or both, would constitute a

of the Borrowers or any Subsidiary prior to, or on, the date hereof in
connection with the transactions contemplated hereby. No statements or
conclusions exist in any Reserve Report which are based upon or include
misleading information or which fail to take into account material information
regarding the matters reported therein to the extent such misstatement,
misleading information or failure could reasonably be expected to have a
Material Adverse Effect.

<PAGE>

Reserve Report, and the ownership or lease of such Properties shall not in any
material respect obligate such Borrower or such Subsidiary to bear the costs and
expenses relating to the maintenance, development and operations of each such
Property in an amount in excess of the working interest of each Property set

corresponding proportionate increase in such Borrower's or such Subsidiary's net
revenue interest in such Property.

                (b) All material leases and agreements necessary for the conduct
of the business of the Borrowers and the Subsidiaries are valid and subsisting,
in full force and effect, and there exists no default or event or circumstance

licensed by the Borrowers and the Subsidiaries including, without limitation,
all easements and rights of way, include all rights and Properties necessary to

Effect. The Borrowers and their Subsidiaries either own or have valid licenses
or other rights to use all databases, geological data, geophysical data,
engineering data, seismic data, maps, interpretations and other technical
information used in their businesses as presently conducted, subject to the

exploration and production of Hydrocarbons, with such exceptions as could not
reasonably be expected to have a Material Adverse Effect.

     Section 7.18 Maintenance of Properties. Except for such acts or failures to
act as could not be reasonably expected to have a Material Adverse Effect, the
Oil and Gas Properties (and Properties unitized therewith) of the Borrowers and
their Subsidiaries have been maintained, operated and developed in a good and
workmanlike manner and in conformity with all Government Requirements and in

their Subsidiaries. Specifically in connection with the foregoing, except for
those as could not be reasonably expected to have a Material Adverse Effect, (i)
no Oil and Gas Property of either of the Borrowers or any Subsidiary is subject
to having

allowable production reduced below the full and regular allowable (including the
maximum permissible tolerance) because of any overproduction (whether or not the

therewith, such unitized Properties) of such Borrower or such Subsidiary. All
pipelines, wells, gas processing plants, platforms and other material
improvements, fixtures and equipment owned in whole or in part by the either of
the Borrowers or any of its Subsidiaries that are reasonably necessary to

by either of the Borrowers or any of its Subsidiaries, in a manner consistent
with such Borrower's or such Subsidiaries' past practices (other than those the
failure of which to maintain in accordance with this Section 7.18 could not
reasonably be expected to have a Material Adverse Effect).

7.19 or on the most recent certificate delivered pursuant to Section 8.12(b), on
a net basis there are no gas imbalances, take or pay or other prepayments which

that they or their Subsidiaries are receiving a price for all production sold
thereunder which is computed substantially in accordance with the terms of the
relevant contract and are not having deliveries curtailed substantially below
the subject Property's delivery capacity), no material agreements exist which
are not cancelable on 60 days notice or less without penalty or detriment for
the sale of production from the Borrowers' or their Subsidiaries' Hydrocarbons
(including, without limitation, calls on or other rights to purchase production,
whether or not the same are currently being exercised) that (a) pertain to the
sale of production at a fixed price and (b) have a maturity or expiry date of
longer than six (6) months, from the date hereof.

the provisions of Regulations T, U or X of the Board.

hereby, (a) the aggregate assets (after giving effect to amounts that could
reasonably be received by reason of indemnity, offset, insurance or any similar
arrangement), at a fair valuation, of the Borrowers and the Guarantors, taken as
a whole, will exceed the aggregate Debt of the Borrowers and the Guarantors on a
consolidated basis, as the Debt becomes absolute and matures, (b) each of the
Borrowers and the Guarantors will not have incurred or intended to incur, and
will not believe that it will incur, Debt beyond its ability to pay such Debt
(after taking into account the timing and amounts of cash to be received by each
of the Borrowers and the Guarantors and the amounts to be payable on or in
respect of its liabilities, and giving effect to amounts that could reasonably
be received by reason of indemnity, offset, insurance or any similar
arrangement) as such Debt becomes absolute and matures and (c) each of the
Borrowers and the Guarantors will not have (and will have no reason to believe
that it will have thereafter) unreasonably small capital for the conduct of its
business.

                (a) Borrowers have no unpaid bills with an invoice date earlier

                        (ii) there are no operations under any of the Operating

will deliver title information in form and substance acceptable to the
Administrative Agent covering enough of the Oil and Gas Properties (excluding

immediately preceding Reserve Report, so that the Administrative Agent shall be
reasonably satisfied with the status of title to or leasehold interests in the
Oil and Gas Properties evaluated by such Reserve Report representing not less
than 80% of the total value of such Properties, provided the Borrowers will not
be required to deliver any title opinions on Oil and Gas Properties that are not
Proved Mineral Interests.

                (b) If the Borrowers have provided title information for
additional Properties under Section 8.13(a), the Borrowers shall, within 90 days

defects or exceptions (including defects or exceptions as to priority) which are
not permitted by Section 9.03 raised by such information, (ii) substitute

on the Oil and Gas Properties evaluated in the most recent Reserve Report, such
default shall not be a Default, but instead the Administrative Agent and/or the
Majority Lenders shall have the right to exercise the following remedy in their
sole discretion from time to time, and any failure to so exercise this remedy at
any time shall not be a waiver as to future exercise of the remedy by the
Administrative Agent or the Lenders. To the extent that the Administrative Agent
or the Majority Lenders are not satisfied with title to any Mortgaged Property
after the 90-day period has elapsed, the Administrative Agent may send a notice
to the Borrowers and the Lenders that the then outstanding PV-10 shall be
reduced by an amount as determined by the Majority Lenders to cause the Borrower
to be in compliance with the requirement to provide acceptable title information
to the Oil and Gas Properties. This new PV-10 shall become effective immediately
after receipt of such notice.

represent at least 80% of the total value of the Oil and Gas Properties
(excluding the Pipeline) evaluated in the most recently completed Reserve Report
after giving effect to exploration and production activities, acquisitions,
dispositions and production. In the event that the Mortgaged Properties do not
represent at least 80% of such total value, then each of the Borrowers shall,
and shall cause their Subsidiaries to, grant, within thirty (30) days of
delivery of the certificate required under Section 8.12(a), to the
Administrative Agent as security for the Indebtedness a first-priority Lien
interest (subject only to Excepted Liens of the type described in clauses (a) to
(d) and (f) of the definition thereof, but subject to the provisos at the end of
such definition) on additional Oil and Gas Properties (excluding the Pipeline)
not already subject to a Lien of the Security Instruments such that after giving
effect thereto, the Mortgaged Properties will represent at least 80% of such
total value. All such Liens will be created and perfected by and in accordance
with the provisions of mortgages, deeds of trust, security agreements and
financing statements or other Security Instruments, all in form and substance
reasonably satisfactory to the Administrative Agent and in sufficient executed
(and acknowledged where necessary or appropriate) counterparts for recording
purposes.

each annual and other report with respect to each Plan or any trust created
thereunder, (ii) promptly upon becoming aware of the occurrence of any ERISA
Event or of any "prohibited transaction," as described in section 406 of ERISA
or in section 4975 of the Code, in connection with any Plan or any trust created

Officer of the applicable Borrower, Subsidiary or ERISA Affiliate, as the case
may be, specifying the nature thereof, what action such Borrower, Subsidiary or
the ERISA Affiliate is taking or proposes to take with respect thereto, and,
when known, any action taken or proposed by the Internal Revenue Service,

                                       52
<PAGE>

the Department of Labor or the PBGC with respect thereto, and (iii) promptly
upon receipt thereof, copies of any notice of the PBGC's intention to terminate
or to have a trustee appointed to administer any Plan. With respect to each Plan
(other than a Multiemployer Plan), each of the Borrowers will, and will cause
each Subsidiary and ERISA Affiliate to, (i) satisfy in full and in a timely
manner, without incurring any late payment or underpayment charge or penalty and
without giving rise to any Lien, all of the contribution and funding
requirements of section 412 of the Code (determined without regard to
subsections (d), (e), (f) and (k) thereof) and of section 302 of ERISA
(determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay,
or cause to be paid, to the PBGC in a timely manner, without incurring any late
payment or underpayment charge or penalty, all premiums required pursuant to

more of their Subsidiaries to maintain the hedged position established by the
Swap Agreements required under Section 6.01(q) during the period specified
therein and shall neither assign, terminate or unwind any such Swap Agreements
nor sell any Swap Agreements if the effect of such action (when taken together
with any other Swap Agreements executed contemporaneously with the taking of
such action) would have the effect of canceling its positions under such Swap
Agreements required hereby.

     Section 8.17 Marketing Activities. The Borrowers will not, and will not
permit any of their Subsidiaries to, engage in marketing activities for any
Hydrocarbons or enter into any contracts related thereto other than (i)
contracts for the sale of Hydrocarbons scheduled or reasonably estimated to be
produced from their proved Oil and Gas Properties during the period of such
contract, (ii) contracts for the sale of Hydrocarbons scheduled or reasonably
estimated to be produced from proved Oil and Gas Properties of third parties
during the period of such contract associated with the Oil and Gas Properties of
the Borrowers and their Subsidiaries that either of the Borrowers or one of its
Subsidiaries has the right to market pursuant to joint operating agreements,
unitization agreements or other similar contracts that are usual and customary
in the oil and gas business and (iii) other contracts for the purchase and/or
sale of Hydrocarbons of third parties (A) which have generally offsetting
provisions (i.e. corresponding pricing mechanics, delivery dates and points and
volumes) such that no "position" is taken and (B) for which appropriate credit
support has been taken to alleviate the material credit risks of the
counterparty thereto.

limitation, any purchase, sale, lease or exchange of Property or the rendering
of any service, with any Affiliate (other than between and among Borrowers and
Wholly-Owned Subsidiaries of either Borrower) unless such transactions are
otherwise permitted under this Agreement and are upon fair and reasonable terms
no less favorable to it than it would obtain in a comparable arm's length
transaction with a Person not an Affiliate other than (a) Investments under
Section 9.05(i), (b) reasonable and customary director, officer and employee
compensation (including bonuses) and other benefits (including retirement,

future time without then or thereafter receiving full payment therefor to exceed
1.5 bcf of gas (on an mcf equivalent basis) in the aggregate.

     Section 9.18 Swap Agreements. The Borrowers will not, and will not permit
any Subsidiary to, enter into any Swap Agreements with any Person other than (a)

Agreements then in effect other than basis differential swaps on volumes already
hedged pursuant to other Swap Agreements) do not exceed, as of the date such
Swap Agreement is executed, 85% of the reasonably anticipated projected
production (as shown in the Borrowers' most recent Reserve Report) from proved,

gas, calculated separately, (b) Swap Agreements in respect of interest rates
with an Approved Counterparty, as follows: (i) Swap Agreements effectively
converting interest rates from fixed to floating, the notional amounts of which

floating) do not exceed 50% of the then outstanding principal amount of the
Borrowers' Debt for borrowed money which bears interest at a fixed rate and (ii)
Swap Agreements effectively converting interest rates from floating to fixed,
the notional amounts of which (when aggregated with all other Swap Agreements of
the Borrowers and their Subsidiaries then in effect effectively converting
interest rates from floating to fixed) do not exceed 75% of the then outstanding
principal amount of the Borrowers' Debt for borrowed money which bears interest
at a floating rate, and (c) Swap Agreements required under Section 6.01(q) or as

such Swap Agreement or to cover market exposures, except to the extent permitted
by Section 9.03(d).

                            The Administrative Agent

     Section 11.01 Appointment; Powers. Each of the Lenders hereby irrevocably
appoints the Administrative Agent as its agent and authorizes the Administrative
Agent to enter into the Intercreditor Agreement on behalf of such Lender (each
Lender hereby agreeing to be bound by the terms of the Intercreditor Agreement
as if it were a party thereto) and to take such other actions on its behalf and
to exercise such powers as are delegated to the Administrative Agent by the
terms hereof and the other Loan Documents, together with such actions and powers
as are reasonably incidental thereto.

     Section 11.02 Duties and Obligations of Administrative Agent. The
Administrative Agent shall not have any duties or obligations except those
expressly set forth in the Loan Documents. Without limiting the generality of
the foregoing, (a) the Administrative Agent shall not be subject to any
fiduciary or other implied duties, regardless of whether a Default has occurred
and is continuing, (b) the Administrative Agent shall not have any duty to take
any discretionary action or exercise any discretionary powers, except as
provided in Section 11.03, and (c) except as expressly set forth herein, the
Administrative Agent shall not have any duty to disclose, and shall not be
liable for the failure to disclose, any information relating to the Borrowers or
any of their Subsidiaries that is communicated to or obtained by the bank
serving as Administrative Agent or any of its Affiliates in any capacity. The
Administrative Agent shall be deemed not to have knowledge of any Default unless
and until written notice thereof is given to the Administrative Agent by either
Borrower or a Lender, and shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in
or in connection with this Agreement or any other Loan Document, (ii) the

under any other Loan Document or in connection herewith or therewith, (iii) the

or as to those conditions precedent expressly required to be to the
Administrative Agent's satisfaction, (vi) the existence, value, perfection or
priority of any collateral security or the financial or other condition of the
Borrowers and their Subsidiaries or any other obligor or guarantor, or (vii) any
failure by either Borrower or any other Person (other than itself) to perform
any of its obligations hereunder or under any other Loan Document or the
performance or observance of any covenants, agreements or other terms or
conditions set forth herein or therein.

     Section 11.03 Action by Administrative Agent. The Administrative Agent
shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly
contemplated hereby that the Administrative Agent is required to exercise in
writing as directed by the Majority Lenders (or such other number or percentage
of the Lenders as shall be necessary under

                                       66
<PAGE>

the circumstances as provided in Section 12.02) and in all cases the
Administrative Agent shall be fully justified in failing or refusing to act
hereunder or under any other Loan Documents unless it shall (a) receive written
instructions from the Majority Lenders or the Lenders, as applicable (or such
other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 12.02) specifying the action to be taken
and (b) be indemnified to its satisfaction by the Lenders against any and all
liability and expenses which may be incurred by it by reason of taking or
continuing to take any such action. The instructions as aforesaid and any action
taken or failure to act pursuant thereto by the Administrative Agent shall be
binding on all of the Lenders. If a Default has occurred and is continuing, then
the Administrative Agent shall take such action with respect to such Default as
shall be directed by the requisite Lenders in the written instructions (with
indemnities) described in this Section 11.03, 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 as it shall deem advisable in
the best interests of the Lenders. In no event, however, shall the
Administrative Agent be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement, the Loan Documents or applicable law. The Administrative Agent shall
not be liable for any action taken or not taken by it with the consent or at the
request of the Majority Lenders or the Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 12.02), and otherwise the Administrative Agent shall not be
liable for any action taken or not taken by it hereunder or under any other Loan
Document or under any other document or instrument referred to or provided for
herein or therein or in connection herewith or therewith, except for its own
gross negligence or willful misconduct.

     Section 11.04 Reliance by Administrative Agent. The Administrative Agent
shall be entitled to rely upon, and shall not incur any liability for relying
upon, any notice, request, certificate, consent, statement, instrument, document
or other writing believed by it to be genuine and to have been signed or sent by
the proper Person. The Administrative Agent also may rely upon any statement
made to it orally or by telephone and believed by it to be made by the proper
Person, and shall not incur any liability for relying thereon and each of the
Borrowers and the Lenders hereby waives the right to dispute the Administrative
Agent's record of such statement, except in the case of gross negligence or
willful misconduct by the Administrative Agent. The Administrative Agent may
consult with legal counsel (who may be counsel for the Borrowers), independent
accountants and other experts selected by it, and shall not be liable for any
action taken or not taken by it in accordance with the advice of any such
counsel, accountants or experts. The Administrative Agent may deem and treat the
payee of the Note, if any, as the holder thereof for all purposes hereof unless
and until a written notice of the assignment or transfer thereof permitted
hereunder shall have been filed with the Administrative Agent.

     Section 11.05 Subagents. The Administrative Agent may perform any and all
its duties and exercise its rights and powers by or through any one or more
sub-agents appointed by the Administrative Agent. The Administrative Agent and
any such sub-agent may perform any and all its duties and exercise its rights
and powers through their

                                       67
<PAGE>

respective Related Parties. The exculpatory provisions of the preceding Sections
of this ARTICLE XI shall apply to any such sub-agent and to the Related Parties
of the Administrative Agent and any such sub-agent, and shall apply to their
respective activities as Administrative Agent.

     Section 11.06 Resignation or Removal of Administrative Agent. Subject to
the appointment and acceptance of a successor Administrative Agent as provided
in this Section 11.06, the Administrative Agent may resign at any time by
notifying the Lenders, and the Borrowers, and the Administrative Agent may be
removed at any time with or without cause by the Majority Lenders. Upon any such
resignation or removal, the Majority Lenders shall have the right, with the
consent of the Borrowers, which consent shall not be unreasonably withheld or
delayed, to appoint a successor. If no successor shall have been so appointed
and shall have accepted such appointment within 30 days after the retiring
Administrative Agent gives notice of its resignation or removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent. Upon the acceptance of
its appointment as Administrative Agent hereunder by a successor, such successor
shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder. The fees
payable by the Borrowers to a successor Administrative Agent shall be the same
as those payable to its predecessor unless otherwise agreed between the
Borrowers and such successor. After the Administrative Agent's resignation
hereunder, the provisions of this ARTICLE XI and Section 12.03 shall continue in
effect for the benefit of such retiring Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while it was acting as Administrative Agent.

     Section 11.07 Administrative Agent as a Lender. Each bank serving as an
Administrative Agent hereunder shall have the same rights and powers in its
capacity as a Lender as any other Lender and may exercise the same as though it
were not an Administrative Agent, and such bank and its Affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
either of the Borrowers or any Subsidiary or other Affiliate thereof as if it
were not an Administrative Agent hereunder.

     Section 11.08 No Reliance. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Lender and based on such documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement and each
other Loan Document to which it is a party. Each Lender also acknowledges that
it will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement, any other Loan Document, any
related agreement or any document furnished hereunder or thereunder. The
Administrative Agent shall not be required to keep themselves informed as to the
performance or observance by either Borrower or any of its Subsidiaries of this
Agreement, the Loan Documents or any other

                                       68
<PAGE>

document referred to or provided for herein or to inspect the Properties or
books of the Borrower or its Subsidiaries. Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
the Administrative Agent hereunder, neither the Administrative Agent nor the
Arranger shall have any duty or responsibility to provide any Lender with any
credit or other information concerning the affairs, financial condition or
business of the Borrowers (or any of their Affiliates) which may come into the
possession of such Administrative Agent or any of its Affiliates. In this
regard, each Lender acknowledges that each of Sidley Austin Brown & Wood LLP and
Haynes and Boone, LLP is acting in this transaction as special counsel to the
Arranger only in respect of the Senior Credit Agreement. Each other party hereto
will consult with its own legal counsel to the extent that it deems necessary in
connection with the Loan Documents and the matters contemplated therein.

     Section 11.09 Authority of Administrative Agent to Release Collateral and
Liens. Each Lender hereby authorizes the Administrative Agent to release any
collateral that is permitted to be sold or released pursuant to the terms of the
Loan Documents. Each Lender hereby authorizes the Administrative Agent to
execute and deliver to the Borrowers, at the Borrowers' sole cost and expense,
any and all releases of Liens, termination statements, assignments or other
documents reasonably requested by the Borrowers in connection with any sale or
other disposition of Property to the extent such sale or other disposition is
permitted by the terms of Section 9.12 or is otherwise authorized by the terms
of the Loan Documents. The Lenders hereby authorize the Administrative Agent, at
its option and in its discretion, to release any Lien granted to or held by the
Administrative Agent upon any Mortgaged Property (i) upon payment and
satisfaction of all of the Indebtedness (other than contingent indemnity
obligations and Indebtedness in respect of Swap Agreements) at any time arising
under or in respect of this Agreement or the Loan Documents or the transactions
contemplated hereby or thereby; (ii) as permitted by, but only in accordance
with, the terms of the applicable Loan Document; or (iii) if approved,
authorized or ratified in writing by the Majority Lenders, unless such release
is required to be approved by all of the Lenders hereunder.

     Section 11.10 The Arranger. The Arranger shall have no duties,
responsibilities or liabilities under this Agreement and the other Loan
Documents.

Documents shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege under any of the Loan Documents
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The rights and remedies of the Administrative Agent
and the Lenders hereunder and under the other Loan Documents are cumulative and
are not exclusive of any rights or remedies that they would otherwise have. No
waiver of any provision of this Agreement or any other Loan Document or consent
to any departure by the Borrowers therefrom shall in any event be effective
unless the same shall be permitted by Section 12.02(b), and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. Without limiting the generality of the foregoing, the making of a
Loan shall not be construed as a waiver of any Default, regardless of whether
the Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

                (b) Neither this Agreement nor any provision hereof nor any
Security Instrument nor any provision thereof may be waived, amended or modified
except

                                       70
<PAGE>

pursuant to an agreement or agreements in writing entered into by the Borrowers
and the Majority Lenders or by the Borrowers and the Administrative Agent with
the consent of the Majority Lenders; provided that no such agreement shall (i)
increase the Commitment of any Lender without the written consent of such
Lender, (ii) modify the definition of PV-10 without the consent of each Lender,
(iii) reduce the principal amount of the Loan or reduce the rate of interest
thereon, or reduce any fees payable hereunder, or reduce any other Indebtedness
hereunder or under any other Loan Document, without the written consent of each
Lender affected thereby, (iv) postpone the scheduled date of payment or
prepayment of the principal amount of the Loan, or any interest thereon, or any
fees payable hereunder, or any other Indebtedness hereunder or under any other
Loan Document, or reduce the amount of, waive or excuse any such payment, or
postpone or extend the Maturity Date without the written consent of each Lender
affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that
would alter the pro rata sharing of payments required thereby, without the
written consent of each Lender, (vi) waive or amend Section 6.01, Section 8.14,
or Section 10.02(c), or change the definition of the term "Subsidiary", without
the written consent of each Lender, (vii) release any Guarantor (except as set
forth in the Guaranty Agreement), release a substantial portion of the
collateral (other than as provided in Section 11.09), or reduce the percentage
set forth in Section 8.14 to less than 80%, without the written consent of each
Lender, or (viii) change any of the provisions of this Section 12.02(b) or the
definition of "Majority Lenders" or any other provision hereof specifying the
number or percentage of Lenders required to waive, amend or modify any rights
hereunder or under any other Loan Documents or make any determination or grant
any consent hereunder or any other Loan Documents, without the written consent
of each Lender; provided further that no such agreement shall amend, modify or
otherwise affect the rights or duties of the Administrative Agent hereunder or
under any other Loan Document without the prior written consent of the
Administrative Agent. Notwithstanding the foregoing, any supplement to Schedule
7.15 (Subsidiaries) shall be effective simply by delivering to the
Administrative Agent a supplemental schedule clearly marked as such and, upon
receipt, the Administrative Agent will promptly deliver a copy thereof to the
Lenders.

INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND

<PAGE>

PROPERTIES OR PAST ACTIVITY ON ANY OF ITS PROPERTIES WHICH, THOUGH LAWFUL AND
FULLY PERMISSIBLE AT THE TIME, COULD RESULT IN PRESENT LIABILITY, (xi) THE
PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED
RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF
OIL, OIL AND GAS WASTES, SOLID WASTES OR HAZARDOUS SUBSTANCES ON OR AT ANY OF

     Section 12.04   Successors and Assigns.
                     ----------------------

                (a) The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that (i) the Borrowers may not assign or
otherwise transfer any of their rights or obligations hereunder without the
prior written consent of each Lender (and any attempted assignment or transfer
by the Borrowers without such consent shall be null and void) and (ii) no Lender
may assign or otherwise transfer its rights or obligations hereunder except in
accordance with this Section 12.04. Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby, Participants
(to the extent provided in Section 12.04(c)) and, to the extent expressly
contemplated hereby, the Related Parties of each of the Administrative Agent and
the Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

                (b) (i) Subject to the conditions set forth in Section 12.04(b)
(ii), any Lender may assign to one or more assignees all or a portion of its
rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans at the time owing to it) with the prior written consent
(such consent not to be unreasonably withheld) of:

                                (A) the Borrowers, provided that no consent of
the Borrowers shall be required for an assignment to a Lender, an Affiliate of a
Lender, an Approved Fund or, if an Event of Default has occurred and is
continuing, any other assignee; and

                                (B) the Administrative Agent, provided that no
consent of the Administrative Agent shall be required for an assignment to an
assignee that is a Lender immediately prior to giving effect to such assignment.

                        (ii) Assignments shall be subject to the following
additional conditions:

                                (A) except in the case of an assignment to a
Lender or an Affiliate of a Lender or an assignment of the entire remaining
amount of the assigning Lender's Commitment or Loans, the amount of the
Commitment or Loans of the assigning Lender subject to each such assignment
(determined as of the date the Assignment and Assumption with respect to such
assignment is delivered to the Administrative Agent) shall not be less than
$5,000,000 unless each of the Borrowers and the Administrative Agent otherwise
consent, provided that no such consent of the Borrowers shall be required if an
Event of Default has occurred and is continuing;

                                (B) each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lender's rights and
obligations under this Agreement;

                                       74
<PAGE>

                                (C) the parties to each assignment shall execute
and deliver to the Administrative Agent an Assignment and Assumption, together
with a processing and recordation fee of $3,500; and

                                (D) the assignee, if it shall not be a Lender,
shall deliver to the Administrative Agent an Administrative Questionnaire.

                        (iii) Subject to Section 12.04(b)(iv) and the acceptance
and recording thereof, from and after the effective date specified in each
Assignment and Assumption the assignee thereunder shall be a party hereto and,
to the extent of the interest assigned by such Assignment and Assumption, have
the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Assumption, be released from its obligations under this Agreement
(and, in the case of an Assignment and Assumption covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Section
5.01, Section 5.02, Section 5.03 and Section 12.03 and subject to the
obligations under Section 5.04). Any assignment or transfer by a Lender of
rights or obligations under this Agreement that does not comply with this
Section 12.04 shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
Section 12.04(c).

                        (iv) The Administrative Agent, acting for this purpose
as an agent of the Borrowers, shall maintain at one of its offices a copy of
each Assignment and Assumption delivered to it and a register for the
recordation of the names and addresses of the Lenders, and Commitments and
principal amount of the Loans, each Lender pursuant to the terms hereof from
time to time (the "Register"). The entries in the Register shall be conclusive,
and the Borrowers, the Administrative Agent, and the Lenders may treat each
Person whose name is recorded in the Register pursuant to the terms hereof as a
Lender hereunder for all purposes of this Agreement, notwithstanding notice to
the contrary. The Register shall be available for inspection by the Borrowers
and any Lender, at any reasonable time and from time to time upon reasonable
prior notice.

                        (v) Upon its receipt of a duly completed Assignment and
Assumption executed by an assigning Lender and an assignee, the assignee's
completed Administrative Questionnaire (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in Section
12.04(b) and any written consent to such assignment required by Section
12.04(b), the Administrative Agent shall accept such Assignment and Assumption
and record the information contained therein in the Register. No assignment
shall be effective for purposes of this Agreement unless it has been recorded in
the Register as provided in this Section 12.04(b).

                (c) (i) Any Lender may, without the consent of the Borrowers or
the Administrative Agent, sell participations to one or more banks or other
entities (a "Participant") in all or a portion of such Lender's rights and
obligations under this Agreement (including all or a portion of its Commitment
and the Loans owing to it);

                                       75
<PAGE>

provided that (A) such Lender's obligations under this Agreement shall remain
unchanged, (B) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations and (C) the Borrowers, the
Administrative Agent, and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver
described in the proviso to Section 12.02 that affects such Participant. In
addition such agreement must provide that the Participant be bound by the
provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrowers
agree that each Participant shall be entitled to the benefits of Section 5.01,
Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to Section 12.04(b). To the extent
permitted by law, each Participant also shall be entitled to the benefits of
Section 12.08 as though it were a Lender, provided such Participant agrees to be
subject to Section 4.01(c) as though it were a Lender.

                        (ii) A Participant shall not be entitled to receive any
greater payment under Section 5.01 or Section 5.03 than the applicable Lender
would have been entitled to receive with respect to the participation sold to
such Participant, unless the sale of the participation to such Participant is
made with the Borrowers' prior written consent. A Participant that would be a
Foreign Lender if it were a Lender shall not be entitled to the benefits of
Section 5.03 unless the Borrowers are notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Borrowers, to
comply with Section 5.03(e) as though it were a Lender.

                (d) Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Lender, including, without limitation, any pledge or
assignment to secure obligations to a Federal Reserve Bank, and this Section
12.04(d) shall not apply to any such pledge or assignment of a security
interest; provided that no such pledge or assignment of a security interest
shall release a Lender from any of its obligations hereunder or substitute any
such pledgee or assignee for such Lender as a party hereto.

                (e) Notwithstanding any other provisions of this Section 12.04,
no transfer or assignment of the interests or obligations of any Lender or any
grant of participations therein shall be permitted if such transfer, assignment
or grant would require the Borrowers and the Guarantors to file a registration
statement with the SEC or to qualify the Loans under the "Blue Sky" laws of any
state.

     Section 12.05   Survival; Revival; Reinstatement.
                     --------------------------------

                (a) All covenants, agreements, representations and warranties
made by the Borrowers herein and in the certificates or other instruments
delivered in connection with or pursuant to this Agreement or any other Loan
Document shall be considered to

                                       76
<PAGE>

have been relied upon by the other parties hereto and shall survive the
execution and delivery of this Agreement and the making of any Loans, regardless
of any investigation made by any such other party or on its behalf and
notwithstanding that the Administrative Agent, or any Lender may have had notice
or knowledge of any Default or incorrect representation or warranty at the time
any credit is extended hereunder, and shall continue in full force and effect as
long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid. The
provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and
ARTICLE XI shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the termination of this Agreement, any other Loan Document or any
provision hereof or thereof.

                (b) To the extent that any payments on the Indebtedness or
proceeds of any collateral are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee,
debtor in possession, receiver or other Person under any bankruptcy law, common
law or equitable cause, then to such extent, the Indebtedness so satisfied shall
be revived and continue as if such payment or proceeds had not been received and
the Administrative Agent's and the Lenders' Liens, security interests, rights,
powers and remedies under this Agreement and each Loan Document shall continue
in full force and effect. In such event, each Loan Document shall be
automatically reinstated and the Borrowers shall take such action as may be
reasonably requested by the Administrative Agent and the Lenders to effect such
reinstatement.

     Section 12.06   Counterparts; Integration; Effectiveness.
                     ----------------------------------------

                (a) This Agreement may be executed in counterparts (and by
different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract.

                (b) THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND ANY SEPARATE
LETTER AGREEMENTS WITH RESPECT TO FEES PAYABLE TO THE ADMINISTRATIVE AGENT
CONSTITUTE THE ENTIRE CONTRACT AMONG THE PARTIES RELATING TO THE SUBJECT MATTER
HEREOF AND THEREOF AND SUPERSEDE ANY AND ALL PREVIOUS AGREEMENTS AND
UNDERSTANDINGS, ORAL OR WRITTEN, RELATING TO THE SUBJECT MATTER HEREOF AND
THEREOF. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL
AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                (c) Except as provided in Section 6.01, this Agreement shall
become effective when it shall have been executed by the Administrative Agent
and when the Administrative Agent shall have received counterparts hereof which,
when taken together, bear the signatures of each of the other parties hereto,
and thereafter shall be

                                       77
<PAGE>

binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

     Section 12.07 Severability. Any provision of this Agreement or any other
Loan Document held to be invalid, illegal or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such invalidity,
illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof or thereof; and the invalidity
of a particular provision in a particular jurisdiction shall not invalidate such
provision in any other jurisdiction.

     Section 12.08 Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender and each of its Affiliates is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other obligations (of whatsoever
kind, including, without limitations obligations under Swap Agreements) at any
time owing by such Lender or Affiliate to or for the credit or the account of
the Borrowers or any Subsidiary against any of and all the obligations of the
Borrowers or any Subsidiary owed to such Lender now or hereafter existing under
this Agreement or any other Loan Document, irrespective of whether or not such
Lender shall have made any demand under this Agreement or any other Loan
Document and although such obligations may be unmatured. The rights of each
Lender under this Section 12.08 are in addition to other rights and remedies
(including other rights of setoff), which such Lender or its Affiliates may
have.

this Agreement or any other Loan Document, (e) in connection with the exercise
of any remedies hereunder or under any other Loan Document or any suit, action
or proceeding relating to this Agreement or any other Loan Document or the
enforcement of rights hereunder or thereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section 12.11, to
(i) any assignee of or Participant in, or any prospective assignee of or
Participant in, any of its rights or obligations under this Agreement (it being
understood that the Persons to whom such disclosure is made will be informed of
the confidential nature of such Information and instructed to keep such
Information confidential) or (ii) any actual or prospective counterparty (or its
advisors) to any Swap Agreement relating to the Borrowers and their obligations
(it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep
such Information confidential), (g) with the consent of the Borrowers or (h) to
the extent such Information (i) becomes publicly available other than as a
result of a breach of this Section 12.11 or (ii) becomes available to the
Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Borrowers. For the purposes of this Section 12.11, "Information"
means all information received from the Borrowers or any Subsidiary relating to
the Borrowers or any Subsidiary and their businesses, other than any such
information that is available to the Administrative Agent or any Lender on a
nonconfidential basis prior to disclosure by the Borrowers or a Subsidiary. Any
Person required to maintain the confidentiality of Information as provided in
this Section 12.11 shall be considered to have complied with its obligation to
do so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information.

     Section 12.12 Interest Rate Limitation. It is the intention of the parties
hereto that each Lender shall conform strictly to usury laws applicable to it.
Accordingly, if the transactions contemplated hereby would be usurious as to any
Lender under laws applicable to it (including the laws of the United States of
America and the State of New York or any other jurisdiction whose laws may be
mandatorily applicable to such Lender notwithstanding the other provisions of
this Agreement), then, in that event, notwithstanding anything to the contrary
in any of the Loan Documents or any agreement entered into in connection with or
as security for the Loans, it is agreed as follows: (i) the aggregate of all
consideration which constitutes interest under law applicable to any Lender that
is contracted for, taken, reserved, charged or received by such Lender under any
of the Loan Documents or agreements or otherwise in connection with the Loans,
shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically and if
theretofore paid shall be credited by such Lender on the principal amount of the
Indebtedness (or, to the extent that the principal amount of the Indebtedness
shall have been or would thereby be paid in full, refunded by such Lender to the
Borrowers); and (ii) in the event that the maturity of the Loans, is accelerated
by reason of an 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 under
law applicable to any Lender may never include more than the maximum amount
allowed by such applicable law, and excess interest, if any, provided for in
this Agreement or otherwise shall be canceled automatically by such Lender as of
the date of such

                                       80
<PAGE>

acceleration or prepayment and, if theretofore paid, shall be credited by such
Lender on the principal amount of the Indebtedness (or, to the extent that the
principal amount of the Indebtedness shall have been or would thereby be paid in
full, refunded by such Lender to the Borrowers). All sums paid or agreed to be
paid to any Lender for the use, forbearance or detention of sums due hereunder
shall, to the extent permitted by law applicable to such Lender, be amortized,
prorated, allocated and spread throughout the stated term of the Loans until
payment in full so that the rate or amount of interest on account of any Loans
hereunder does not exceed the maximum amount allowed by such applicable law. If
at any time and from time to time (i) the amount of interest payable to any
Lender on any date shall be computed at the Highest Lawful Rate applicable to
such Lender pursuant to this Section 12.12 and (ii) in respect of any subsequent
interest computation period the amount of interest otherwise payable to such
Lender would be less than the amount of interest payable to such Lender computed
at the Highest Lawful Rate applicable to such Lender, then the amount of
interest payable to such Lender in respect of such subsequent interest
computation period shall continue to be computed at the Highest Lawful Rate
applicable to such Lender until the total amount of interest payable to such
Lender shall equal the total amount of interest which would have been payable to
such Lender if the total amount of interest had been computed without giving
effect to this Section 12.12.

     Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS
AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS,
CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY
INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING
ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED
THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT
IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS
RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT
IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD
NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT
"CONSPICUOUS."

     Section 12.14 Collateral Matters; Swap Agreements. The benefit of the
Security Instruments and of the provisions of this Agreement relating to any
collateral securing the Indebtedness shall also extend to and be available to
those Lenders or their Affiliates and other Persons which are counterparties to
any Swap Agreement with either Borrower or any of its Subsidiaries on a pro rata
basis in respect of any obligations of the Borrowers

                                       81
<PAGE>

or any of their Subsidiaries which arise under any such Swap Agreement entered
into while such Person or its Affiliate is a Lender, including any Swap
Agreements between such Persons in existence prior to the date hereof. No Lender
or any Affiliate of a Lender shall have any voting rights under any Loan
Document as a result of the existence of obligations owed to it under any such
Swap Agreements.

     Section 12.15 No Third Party Beneficiaries. The lenders under the Senior
Credit Agreement are express beneficiaries of Annex II of this Agreement, and
this Agreement, the other Loan Documents, and the agreement of the Lenders to
make Loans hereunder are solely for the benefit of the Borrowers, and no other
Person (including, without limitation, any Subsidiary, any obligor, contractor,
subcontractor, supplier or materialsman) shall have any rights, claims, remedies
or privileges hereunder or under any other Loan Document against the
Administrative Agent or any Lender for any reason whatsoever. There are no third
party beneficiaries.

     Section 12.16 USA Patriot Act Notice. Each Lender hereby notifies the
Borrower that pursuant to the requirements of the USA Patriot Act (Title III of
Pub. L. 107-56 (signed into law October 26, 2001)) (the "Act"), it is required
to obtain, verify and record information that identifies the Borrowers, which
information includes the name and address of the Borrowers and other information
that will allow such Lender to identify the Borrowers in accordance with the
Act.

        (vii)     all Investment Property;

       (viii)     all Intellectual Property Collateral;

         (ix)     the Commercial Tort Claims described on Schedule 15 to the
                  Perfection Certificate;

                  sentence, all other personal property of such Pledgor, whether
                  tangible or intangible, and all Proceeds and products of
                  each of the foregoing and all accessions to, substitutions
                  and replacements for, and rents, profits and products of,

                  nity, warranty or guaranty payable to such Pledgor from time
                  to time with respect to any of the foregoing.

          Notwithstanding anything to the contrary contained in clauses (i)
through (xv) above, the security interest created by this Agreement shall not
extend to, and the term "Pledged Collateral" shall not include, any Excluded
Property, and (i) the Pledgors shall from time to time (but no more frequently
than quarterly) at the request of the Administrative Agent give written notice
to the Administrative Agent identifying in reasonable detail the Special
Property (and stating in such notice that such Special Property constitutes
"Excluded Property") and shall provide to the Administrative Agent such other
information regarding the Special Property as the Administrative Agent may
reasonably request and (ii) from and after the Effective Date, no Pledgor shall
permit to become effective in any document creating, governing or providing for
any permit, lease or license, a provision that would prohibit the creation of a
Lien on such permit, lease or license in favor of the Administrative Agent
unless such Pledgor believes, in its reasonable judgment, that such prohibition
is usual and customary in transactions of such type.

          SECTION 2.2. Filings. (a) Each Pledgor hereby irrevocably authorizes
the Administrative Agent at any time and from time to time to file in any
relevant jurisdiction any initial financing statements (including fixture
filings) and amendments thereto that contain the information required by Article
9 of the Uniform Commercial Code of each applicable jurisdiction for the filing
of any financing statement or amendment relating to the Pledged Collateral,
including (i) whether such Pledgor is an organization, the type of organization
and any organizational identification number issued to such Pledgor, (ii) any
financing or continuation statements or other documents without the signature of
such Pledgor where permitted by law, including the filing of a financing
statement describing the Pledged Collateral as "all assets in which the Pledgor
now owns or hereafter acquires rights" and (iii) in the case of a financing
statement filed as a fixture filing or covering Pledged Collateral constituting
oil, gas, minerals to be extracted, other As-extracted collateral or timber to
be cut, a sufficient description of the real property to which such Pledged
Collateral relates. Each Pledgor agrees to provide all information described in
the immediately preceding sentence to the Administrative Agent promptly upon
request.

          (b) Each Pledgor hereby ratifies its authorization for the
Administrative Agent to file in any relevant jurisdiction any initial financing
statements or amendments thereto relating to the Pledged Collateral if filed
prior to the date hereof.

          (c) Each Pledgor hereby further authorizes the Administrative
Agent to file filings with the United States Patent and Trademark Office or
United States Copyright Office (or any successor office or any similar office in
any other country), including this Agreement, the Copyright Security Agreement,
the Patent Security Agreement and the Trademark Security Agreement, or other
documents for the purpose of perfecting, confirming, continuing, enforcing or
protecting the security interest granted by such Pledgor hereunder, without the
signature of such Pledgor, and naming such Pledgor, as debtor, and the
Administrative Agent, as secured party.

                  PERFECTION; SUPPLEMENTS; FURTHER ASSURANCES;
                            USE OF PLEDGED COLLATERAL

          SECTION 3.1.  Delivery of Certificated Securities Collateral. Each
Pledgor represents and warrants that all certificates, agreements or instruments
representing or evidencing the Securities Collateral in existence on the date
hereof have been delivered to the Administrative Agent in suitable form for
transfer by delivery or accompanied by duly executed instruments of transfer or
assignment in blank and that the Administrative Agent has a perfected first
priority security interest therein. Each Pledgor hereby agrees that all
certificates, agreements or instruments representing or evidencing Securities
Collateral acquired by such Pledgor after the date hereof shall promptly upon
receipt thereof by such Pledgor be delivered to and held by or on behalf of the
Administrative Agent pursuant hereto. All certificated Securities Collateral
shall be in suitable form for transfer by delivery or shall be accompanied by
duly executed instruments of transfer or assignment in blank, all in form and
substance reasonably satisfactory to the Administrative Agent. The
Administrative Agent shall have the right, at any time upon the occurrence and
during the continuance of any Event of Default, to endorse, assign or otherwise
transfer to or to register in the name of the Administrative Agent or any of its
nominees or endorse for negotiation any or all of the Securities Collateral,
without any indication that such Securities Collateral is subject to the
security interest hereunder. In addition, upon the occurrence and during the
continuance of an Event of Default, the Administrative Agent shall have the
right at any time to exchange certificates representing or evidencing Securities
Collateral for certificates of smaller or larger denominations.

          SECTION 3.2. Perfection of Uncertificated Securities Collateral.
Each Pledgor represents and warrants that the Administrative Agent has a
perfected first priority security interest in all uncertificated Pledged
Securities pledged by it hereunder that are in existence on the date hereof.
Each Pledgor hereby agrees that if any of the Pledged Securities are at any time
not evidenced by certificates of ownership, then each applicable Pledgor shall,
to the extent permitted by applicable law (i) if necessary or desirable to
perfect a security interest in such Pledged Securities, cause such pledge to be
recorded on the equityholder register or the books of the issuer, cause the
issuer to execute and deliver to the Administrative Agent an acknowledgment of
the pledge of such Pledged Securities substantially in the form of Exhibit 1
annexed hereto, execute any customary pledge forms or other documents necessary
or appropriate to complete the pledge and give the Administrative Agent the
right to transfer such Pledged Securities under the terms hereof and, upon
request, provide to the Administrative Agent an opinion of counsel, in form and
substance reasonably satisfactory to the Administrative Agent, confirming such
pledge and perfection thereof and (ii) use its commercially reasonable efforts
to cause such Pledged Securities to become certificated and delivered to the
Administrative Agent in accordance with the provisions of Section 3.1.

          SECTION 3.3. Financing Statements and Other Filings; Maintenance
of Perfected Security Interest. Each Pledgor represents and warrants that all
filings necessary to per-

<PAGE>

                                      -14-

fect the security interest granted by it to the Administrative Agent in respect
of the Pledged Collateral have been delivered to the Administrative Agent in
completed and, to the extent necessary or appropriate, duly executed form for
filing in each governmental, municipal or other office specified in Schedule 7
annexed to the Perfection Certificate (to the extent required to be listed on
the schedules to the Perfection Certificate as of the date this representation
is made or deemed made). Each Pledgor agrees that at the sole cost and expense
of the Pledgors, (i) such Pledgor will maintain the security interest created by
this Agreement in the Pledged Collateral as a perfected first priority security
interest and shall defend such security interest against the claims and demands
of all persons except Liens permitted under the Credit Agreement, (ii) such
Pledgor shall furnish to the Administrative Agent from time to time (but no more
frequently than quarterly) statements and schedules further identifying and
describing the Pledged Collateral and such other reports in connection with the
Pledged Collateral as the Administrative Agent may reasonably request, all in
reasonable detail and (iii) at any time and from time to time, upon the written
request of the Administrative Agent, such Pledgor shall promptly and duly
execute and deliver, and file and have recorded, such further instruments and
documents and take such further action as the Administrative Agent may
reasonably request for the purpose of obtaining or preserving the full benefits
of this Agreement and the rights and powers herein granted, including the filing
of any financing statements, continuation statements and other documents
(including this Agreement) under the Uniform Commercial Code (or other similar
laws) in effect in any jurisdiction with respect to the security interest
created hereby and the execution and delivery of Control Agreements, all in form
reasonably satisfactory to the Administrative Agent and in such offices
(including the United States Patent and Trademark Office and the United States
Copyright Office) wherever required by law to perfect, continue and maintain a
valid, enforceable, first priority security interest in the Pledged Collateral
as provided herein and to preserve the other rights and interests granted to the
Administrative Agent hereunder, as against third parties, with respect to the
Pledged Collateral.

          SECTION 3.4. Other Actions. In order to further insure the
attachment, perfection and priority of, and the ability of the Administrative
Agent to enforce, the Administrative Agent's security interest in the Pledged
Collateral, each Pledgor represents and warrants (as to itself) as follows and
agrees, in each case at such Pledgor's own expense, to take the following
actions with respect to the following Pledged Collateral:

          (a) Instruments and Tangible Chattel Paper. (i) No amounts
     payable under or in connection with any of the Pledged Collateral are
     evidenced by any Instrument or Tangible Chattel Paper other than
     such Instruments and Tangible Chattel Paper listed in Schedule 12
     annexed to the Perfection Certificate (to the extent required to be listed
     on the schedules to the Perfection Certificate as of the date this
     representation is made or deemed made) and (ii) each Instrument and each
     item of Tangible Chattel Paper listed in Schedule 12 annexed to the
     Perfection Certificate has been properly endorsed, assigned and delivered
     to the Administrative Agent, accompanied by instruments of transfer or
     assignment duly executed in blank.  If any amount then payable under or in
     connection with any of the Pledged Collateral shall be evidenced by any
     Instrument or Tangible Chattel Paper, and such amount, together with all
     amounts payable evidenced by any Instrument

<PAGE>

                                      -15-

     or Tangible Chattel Paper not previously delivered to the Administrative
     Agent exceeds $500,000 in the aggregate for all Pledgors, the Pledgor
     acquiring such Instrument or Tangible Chattel Paper shall forthwith
     endorse, assign and deliver the same to the Administrative Agent,
     accompanied by such instruments of transfer or assignment duly executed in
     blank as the Administrative Agent may from time to time specify.

          (b) Deposit Accounts. (i) Each Pledgor has neither opened nor
     maintains any Deposit Accounts other than the accounts listed in Schedule
     16 annexed to the Perfection Certificate (to the extent required to be
     listed on the schedules to the Perfection Certificate as of the date this
     representation is made or deemed made) and (ii) the Administrative Agent
     has a perfected first priority security interest in each Deposit Account
     listed in Schedule 16 annexed to the Perfection Certificate by Control to
     the extent a fully executed Deposit Account Control Agreement is in effect
     covering such Deposit Account. No Pledgor shall hereafter establish and
     maintain any Deposit Account unless (1) the applicable Pledgor shall have
     given the Administrative Agent 30 days' prior written notice of its
     intention to establish such new Deposit Account with a Bank, (2) such Bank
     shall be reasonably acceptable to the Administrative Agent and (3) if
     requested by the Administrative Agent, such Bank and such Pledgor shall
     have duly executed and delivered to the Administrative Agent a Deposit
     Account Control Agreement with respect to such Deposit Account. Each
     Pledgor agrees that, with respect to each Deposit Account in existence on
     the date hereof and at the time it establishes any additional Deposit
     Accounts, it shall (to the extent requested by the Administrative Agent)
     enter into a duly authorized, executed and delivered Deposit Account
     Control Agreement with respect to such Deposit Account. The Administrative
     Agent agrees with each Pledgor that the Administrative Agent shall not give
     any instructions directing the disposition of funds from time to time
     credited to any Deposit Account or withhold any withdrawal rights from such
     Pledgor with respect to funds from time to time credited to any Deposit
     Account unless an Event of Default has occurred and is continuing. The
     provisions of this Section 3.4(b) shall not apply to the Collateral Account
     or any other Deposit Account for which the Administrative Agent is the
     Bank. No Pledgor shall grant Control of any Deposit Account to any person
     other than the Administrative Agent.

          (c) Investment Property. (i) Each Pledgor (1) has no Securities
     Accounts or Commodity Accounts other than those listed in Schedule 16
     annexed to the Perfection Certificate (to the extent required to be listed
     on the schedules to the Perfection Certificate as of the date this
     representation is made or deemed made) and the Administrative Agent has a
     perfected first priority security interest in such Securities Accounts and
     Commodity Accounts by Control, (2) does not hold, own or have any interest
     in any certificated securities or uncertificated securities other than
     those constituting Pledged Securities and those maintained in Securities
     Accounts or Commodity Accounts listed in Schedule 16 annexed to the
     Perfection Certificate (to the extent required to be listed on the
     schedules to the Perfection Certificate as of the date this representation
     is made or deemed made) and (3) as of the date hereof, has entered into a
     duly authorized, executed and delivered Securities Account Control
     Agreement or a Commodity Account Control

<PAGE>

                                      -16-

     Agreement with respect to each Securities Account or Commodity Account
     listed in Schedule 16 annexed to the Perfection Certificate, as
     applicable.

          (ii) If any Pledgor shall at any time hold or acquire any certificated
     securities constituting Investment Property, such Pledgor shall promptly
     (a) endorse, assign and deliver the same to the Administrative Agent,
     accompanied by such instruments of transfer or assignment duly executed in
     blank, all in form and substance reasonably satisfactory to the
     Administrative Agent or (b) deliver such securities into a Securities
     Account with respect to which a Control Agreement is in effect in favor of
     the Administrative Agent. If any securities now or hereafter acquired by
     any Pledgor constituting Investment Property are uncertificated and are
     issued to such Pledgor or its nominee directly by the issuer thereof, such
     Pledgor shall promptly notify the Administrative Agent thereof and pursuant
     to an agreement in form and substance reasonably satisfactory to the
     Administrative Agent, either (a) cause the issuer to agree to comply with
     instructions from the Administrative Agent as to such securities, without
     further consent of any Pledgor or such nominee, (b) cause a Security
     Entitlement with respect to such uncertificated security to be held in a
     Securities Account with respect to which the Administrative Agent has
     Control or (c) arrange for the Administrative Agent to become the
     registered owner of the securities. Pledgor shall not hereafter establish
     and maintain any Securities Account or Commodity Account with any
     Securities Intermediary or Commodity Intermediary unless (1) the applicable
     Pledgor shall have given the Administrative Agent 30 days' prior written
     notice of its intention to establish such new Securities Account or
     Commodity Account with such Securities Intermediary or Commodity
     Intermediary, (2) such Securities Intermediary or Commodity Intermediary
     shall be reasonably acceptable to the Administrative Agent and (3) such
     Securities Intermediary or Commodity Intermediary, as the case may be, and
     such Pledgor shall have duly executed and delivered a Control Agreement
     with respect to such Securities Account or Commodity Account, as the case
     may be. Each Pledgor shall accept any cash and Investment Property in trust
     for the benefit of the Administrative Agent and within one (1) Business Day
     of actual receipt thereof, deposit any cash or Investment Property and any
     new securities, instruments, documents or other property by reason of
     ownership of the Investment Property (other than payments of a kind
     described in Section 7.4 hereof) received by it into a Deposit Account or
     Securities Account subject to Administrative Agent's Control. The
     Administrative Agent agrees with each Pledgor that the Administrative Agent
     shall not give any Entitlement Orders or instructions or directions to any
     issuer of uncertificated securities, Securities Intermediary or Commodity
     Intermediary, and shall not withhold its consent to the exercise of any
     withdrawal or dealing rights by such Pledgor, unless an Event of Default
     has occurred and is continuing, or, after giving effect to any such
     investment and withdrawal rights would occur. The provisions of this
     Section 3.4(c) shall not apply to any Financial Assets credited to a
     Securities Account for which the Administrative Agent is the Securities
     Intermediary. No Pledgor shall grant control over any Investment Property
     to any person other than the Administrative Agent.

                                      -17-

          (iii)  As between the Administrative Agent and the Pledgors, the
     Pledgors shall bear the investment risk with respect to the Investment
     Property and Pledged Securities, and the risk of loss of, damage to, or the
     destruction of the Investment Property and Pledged Securities, whether in
     the possession of, or maintained as a security entitlement or deposit by,
     or subject to the control of, the Administrative Agent, a Securities
     Intermediary, Commodity Intermediary, any Pledgor or any other person;
     provided, however, that nothing contained in this Section 3.4(c) shall
     release or relieve any Securities Intermediary or Commodity Intermediary
     of its duties and obligations to the Pledgors or any other person under any
     Control Agreement or under applicable law. Each Pledgor shall promptly pay
     all Claims and fees of whatever kind or nature with respect to the
     Investment Property and Pledged Securities pledged by it under this
     Agreement. In the event any Pledgor shall fail to make such payment
     contemplated in the immediately preceding sentence, the Administrative
     Agent may do so for the account of such Pledgor and the Pledgors shall
     promptly reimburse and indemnify the Administrative Agent from all costs
     and expenses incurred by the Administrative Agent under this Section 3.4(c)
     in accordance with Section 12.03 of the Credit Agreement.

          (d) Electronic Chattel Paper and Transferable Records. No amount
     under or in connection with any of the Pledged Collateral is evidenced by
     any Electronic Chattel Paper or any "transferable record" (as that term is
     defined in Section 201 of the Federal Electronic Signatures in Global and
     National Commerce Act, or in Section 16 of the Uniform Electronic
     Transactions Act as in effect in any relevant jurisdiction) other than
     such Electronic Chattel Paper and transferable records listed in
     Schedule 12 annexed to the Perfection Certificate (to the extent required
     to be listed on the schedules to the Perfection Certificate as of the date
     this representation is made or deemed made).  If any amount payable under
     or in connection with any of the Pledged Collateral shall be evidenced by
     any Electronic Chattel Paper or any transferable record, the Pledgor
     acquiring such Electronic Chattel Paper or transferable record
     shall promptly notify the Administrative Agent thereof and shall take such
     action as the Administrative Agent may reasonably request to vest in the
     Administrative Agent control under UCC Section 9-105 of such Electronic
     Chattel Paper or control under Section 201 of the Federal Electronic
     Signatures in Global and National Commerce Act or, as the case may be,
     Section 16 of the Uniform Electronic Transactions Act, as so in effect in
     such jurisdiction, of such transferable record.  The requirement in the
     preceding sentence shall apply to the extent that such amount, together
     with all amounts payable evidenced by Electronic Chattel Paper or any
     transferable record in which the Administrative Agent has not been vested
     control within the meaning of the statutes described in this sentence
     exceeds $500,000 in the aggregate for all Pledgors.  The Administrative
     Agent agrees with such Pledgor that the Administrative Agent will arrange,
     pursuant to procedures satisfactory to the Administrative Agent and so
     long as such procedures will not result in the Administrative Agent's loss
     of control, for the Pledgor to make alterations to the Electronic Chattel
     Paper or transferable record permitted under UCC Section 9-105 or, as the
     case may be, Section 201 of the Federal Electronic Signatures in Global
     and National Commerce Act or Section 16 of the Uniform Electronic
     Transactions Act for a party in control to allow without loss of con-

<PAGE>

                                      -18-

     trol, unless an Event of Default has occurred and is continuing or would
     occur after taking into account any action by such Pledgor with respect to
     such Electronic Chattel Paper or transferable record.

          (e)  Letter-of-Credit Rights.  If any Pledgor is at any time a
     beneficiary under a Letter of Credit now or hereafter issued in favor of
     such Pledgor, other than a Letter of Credit issued pursuant to the Credit
     Agreement, such Pledgor shall promptly notify the Administrative Agent
     thereof and such Pledgor shall, at the request of the Administrative Agent,
     pursuant to an agreement in form and substance reasonably satisfactory to
     the Administrative Agent, either (i) arrange for the issuer and any
     confirmer of such Letter of Credit to consent to an assignment to the
     Administrative Agent of the proceeds of any drawing under the Letter of
     Credit or (ii) arrange for the Administrative Agent to become the
     transferee beneficiary of such Letter of Credit, with the Administrative
     Agent agreeing, in each case, that the proceeds of any drawing
     under the Letter of Credit are to be applied as provided in the Credit
     Agreement. The actions in the preceding sentence shall be taken to the
     extent that the amount under such Letter of Credit, together with all
     amounts under Letters of Credit for which the actions described above in
     clause (i) and (ii) have not been taken, exceeds $500,000 in the aggregate
     for all Pledgors.

          (f)  Commercial Tort Claims.  As of the date hereof each Pledgor
     hereby represents and warrants that it holds no Commercial Tort Claims
     other than those listed in Schedule 15 annexed to the Perfection
     Certificate (to the extent required to be listed on the schedules to the
     Perfection Certificate as of the date this representation is made or
     deemed made).  If any Pledgor shall at any time hold or acquire a
     Commercial Tort Claim having a value together with all other Commercial
     Tort Claims of all Pledgors in which the Administrative Agent does not have
     a security interest in excess of $500,000 in the aggregate, such Pledgor
     shall immediately notify the Administrative Agent in writing signed by such
     Pledgor of the brief details thereof and grant to the Administrative Agent
     in such writing a security interest therein and in the Proceeds thereof,
     all upon the terms of this Agreement, with such writing to be in form and
     substance reasonably satisfactory to the Administrative Agent.

          (g)  Landlord's Access Agreements/Bailee Letters.  Each Pledgor shall,
     following the reasonable request of the Administrative Agent, use its
     commercially reasonable efforts to obtain as soon as practicable after the
     date of such request, with respect to each location required by the
     Administrative Agent, where such Pledgor maintains Pledged Collateral, a
     Bailee Letter and/or Landlord Access Agreement, as applicable, and use
     commercially reasonable efforts to obtain a Bailee Letter, Landlord Access
     Agreement and/or landlord's lien waiver, as applicable, from all such
     bailees and landlords, as applicable, who from time to time have possession
     of Pledged Collateral in the ordinary course of such Pledgor's business.
     A waiver of bailee's lien shall not be required if the value of the
     Pledged Collateral held by such bailee is less than $100,000, provided that
     the aggregate value of the Pledged Collateral held by all bailees who have
     not delivered a Bailee Letter is less than $500,000 in the aggregate.

                                      -19-

          (h)  Motor Vehicles. Upon the request of the Administrative Agent,
     each Pledgor shall deliver to the Administrative Agent originals of the
     certificates of title or ownership for the motor vehicles (and any other
     Equipment covered by Certificates of Title or ownership) owned by it with
     the Administrative Agent listed as lienholder therein. Such requirement
     shall apply to the Pledgors if any such motor vehicle (or any such other
     Equipment) is valued at over $50,000.

          SECTION 3.5.  Joinder of Additional Guarantors. The Pledgors shall
cause each Subsidiary of Quest Resource Corporation which, from time to time,
after the date hereof shall be required to pledge any assets to the
Administrative Agent for the benefit of the Secured Parties pursuant to the
provisions of the Credit Agreement, (a) to execute and deliver to the
Administrative Agent (i) a Joinder Agreement substantially in the form of
Exhibit 3 annexed hereto within thirty (30) Business Days on which it was
acquired or created and (ii) a Perfection Certificate, in each case, within
thirty (30) Business Days of the date on which it was acquired or created or (b)
in the case of a Subsidiary organized outside of the United States required to
pledge any assets to the Administrative Agent, execute and deliver such
documentation as the Administrative Agent shall reasonably request and, in each
case, upon such execution and delivery, such Subsidiary shall constitute a
"Guarantor" and a "Pledgor" for all purposes hereunder with the same force and
effect as if originally named as a Guarantor and Pledgor herein. The execution
and delivery of such Joinder Agreement shall not require the consent of any
Pledgor hereunder. The rights and obligations of each Pledgor hereunder shall
remain in full force and effect notwithstanding the addition of any new
Guarantor and Pledgor as a party to this Agreement.

          SECTION 3.6.  Supplements; Further Assurances. Each Pledgor shall take
such further actions, and execute and deliver to the Administrative Agent such
additional assignments, agreements, supplements, powers and instruments, as the
Administrative Agent may in its reasonable judgment deem necessary or
appropriate, wherever required by law, in order to perfect, preserve and protect
the security interest in the Pledged Collateral as provided herein and the
rights and interests granted to the Administrative Agent hereunder, to carry
into effect the purposes hereof or better to assure and confirm unto the
Administrative Agent the Pledged Collateral or permit the Administrative Agent
to exercise and enforce its rights, powers and remedies hereunder with respect
to any Pledged Collateral. Without limiting the generality of the foregoing,
each Pledgor shall make, execute, endorse, acknowledge, file or refile and/or
deliver to the Administrative Agent from time to time upon reasonable request
such lists, descriptions and designations of the Pledged Collateral, copies of
warehouse receipts, receipts in the nature of warehouse receipts, bills of
lading, documents of title, vouchers, invoices, schedules, confirmatory
assignments, supplements, additional security agreements, conveyances, financing
statements, transfer endorsements, powers of attorney, certificates, reports and
other assurances or instruments as the Administrative Agent shall reasonably
request. If an Event of Default has occurred and is continuing, the
Administrative Agent may institute and maintain, in its own name or in the name
of any Pledgor, such suits and proceedings as the Administrative Agent may be
advised by counsel shall be necessary or expedient to prevent any impairment of
the security interest in or the perfection thereof in the Pledged Collateral.
All of the foregoing shall be at the sole cost and expense of the Pledgors.

                                   ARTICLE IV

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

          Each Pledgor represents, warrants and covenants as follows:

          SECTION 4.1. Title.  Except for the security interest granted to the
Administrative Agent for the ratable benefit of the Secured Parties pursuant to
this Agreement and Liens permitted under the Credit Agreement, such Pledgor owns
and, as to Pledged Collateral acquired by it from time to time after the date
hereof, will own the rights in each item of Pledged Collateral pledged by it
hereunder free and clear of any and all Liens or claims of others other than
Liens permitted under the Credit Agreement. In addition, no Liens or claims
exist on the Securities Collateral, other than as permitted by Section 9.03 of
the Credit Agreement. Such Pledgor has not filed, nor authorized any third party
to file a financing statement or other public notice with respect to all or any
part of the Pledged Collateral on file or of record in any public office, except
such as have been filed in favor of the Administrative Agent pursuant to this
Agreement or as are permitted by the Credit Agreement or financing statements or
public notices relating to the termination statements listed on Schedule 9 to
the Perfection Certificate. No person other than the Administrative Agent has
control or possession of all or any part of the Pledged Collateral, except as
permitted by the Credit Agreement.

          SECTION 4.2.  Validity of Security Interest. The security interest in
and Lien on the Pledged Collateral granted to the Administrative Agent for the
benefit of the Secured Parties hereunder constitutes (a) a legal and valid
security interest in all the Pledged Collateral securing the payment and
performance of the Indebtedness, and (b) subject to the filings and other
actions described in Schedule 7 annexed to the Perfection Certificate (to the
extent required to be listed on the schedules to the Perfection Certificate as
of the date this representation is made or deemed made), a perfected security
interest in all the Pledged Collateral. The security interest and Lien granted
to the Administrative Agent for the benefit of the Secured Parties pursuant to
this Agreement in and on the Pledged Collateral will at all times constitute a
perfected, continuing security interest therein, subject only to Liens permitted
under the Credit Agreement.

          SECTION 4.3. Defense of Claims; Transferability of Pledged Collateral.
Each Pledgor shall, at its own cost and expense, defend title to the Pledged
Collateral pledged by it hereunder and the security interest therein and Lien
thereon granted to the Administrative Agent and the priority thereof against all
claims and demands of all persons, at its own cost and expense, at any time
claiming any interest therein adverse to the Administrative Agent or any other
Secured Party other than Liens permitted under the Credit Agreement (other than
Contested Liens). There is no agreement, and no Pledgor shall enter into any
agreement or take any other action, that would restrict the transferability of
any of the Pledged Collateral or otherwise impair or conflict with such
Pledgors' obligations or the rights of the Administrative Agent hereunder.

          SECTION 4.4.  Other Financing Statements. It has not filed, nor
authorized any third party to file (nor will there be any) valid or effective
financing statement (or similar state-

<PAGE>

                                      -21-

ment or instrument of registration under the law of any jurisdiction) covering
or purporting to cover any interest of any kind in the Pledged Collateral other
than financing statements and other statements and instruments relating to Liens
permitted under the Credit Agreement. So long as any of the Indebtedness remain
unpaid, no Pledgor shall execute, authorize or permit to be filed in any public
office any financing statement (or similar statement or instrument of
registration under the law of any jurisdiction) relating to any Pledged
Collateral, except financing statements and other statements and instruments
filed or to be filed in respect of and covering the security interests granted
by such Pledgor to the holder of the Liens permitted under the Credit Agreement.

          SECTION 4.5. Chief Executive Office; Change of Name; Jurisdiction of
Organization. (a) It shall comply with the provisions of Section 7.16 of the
Credit Agreement.

          (b) The Administrative Agent may rely on opinions of counsel as to
whether any or all UCC financing statements of the Pledgors need to be amended
as a result of any of the changes to the information provided in Section 5.13(a)
of the Credit Agreement. If any Pledgor fails to provide information to the
Administrative Agent about such changes on a timely basis, the Administrative
Agent shall not be liable or responsible to any party for any failure to
maintain a perfected security interest in such Pledgor's property constituting
Pledged Collateral, for which the Administrative Agent needed to have
information relating to such changes. The Administrative Agent shall have no
duty to inquire about such changes if any Pledgor does not inform the
Administrative Agent of such changes, the parties acknowledging and agreeing
that it would not be feasible or practical for the Administrative Agent to
search for information on such changes if such information is not provided by
any Pledgor.

          SECTION 4.6. Location of Inventory and Equipment. It shall not move
any Equipment or Inventory to any location other than one within the continental
United States until (i) it shall have given the Administrative Agent not less
than 30 days' prior written notice (in the form of an Officers' Certificate) of
its intention so to do, clearly describing such new location and providing such
other information in connection therewith as the Administrative Agent may
request and (ii) with respect to such new location, such Pledgor shall have
taken all action reasonably satisfactory to the Administrative Agent to maintain
the perfection and priority of the security interest of the Administrative Agent
for the benefit of the Secured Parties in the Pledged Collateral intended to be
granted hereby, including using commercially reasonable efforts to obtain
waivers of landlord's or warehousemen's and/or bailee's liens with respect to
such new location, if applicable, and if reasonably requested by the
Administrative Agent. Such Pledgor agrees to provide the Administrative Agent
with prompt notice following the movement of any Equipment or Inventory to any
location other than one that is listed in the relevant Schedules to the
Perfection Certificate.

          SECTION 4.7. Due Authorization and Issuance. All of the Initial
Pledged Shares have been, and to the extent any Pledged Shares are hereafter
issued, such Pledged Shares will be, upon such issuance, duly authorized,
validly issued and fully paid and non-assessable. All of the Initial Pledged
Interests have been fully paid for, and there is no amount or other obligation
owing by any Pledgor to any issuer of the Initial Pledged Interests in exchange
for or in

<PAGE>

                                      -22-

connection with the issuance of the Initial Pledged Interests or any Pledgor's
status as a partner or a member of any issuer of the Initial Pledged Interests.

          SECTION 4.8. Consents, etc. In the event that the Administrative Agent
desires to exercise any remedies, voting or consensual rights or
attorney-in-fact powers set forth in this Agreement and determines it necessary
to obtain any approvals or consents of any Governmental Authority or any other
person therefor, then, upon the reasonable request of the Administrative Agent,
such Pledgor agrees to use its best efforts to assist and aid the Administrative
Agent to obtain as soon as practicable any necessary approvals or consents for
the exercise of any such remedies, rights and powers.

          SECTION 4.9. Pledged Collateral. All information set forth herein,
including the schedules annexed hereto, and all information contained in any
documents, schedules and lists heretofore delivered to any Secured Party,
including the Perfection Certificate and the schedules thereto, in connection
with this Agreement, in each case, relating to the Pledged Collateral, is
accurate and complete in all material respects. The Pledged Collateral described
on the schedules annexed to the Perfection Certificate constitutes all of the
property of such type of Pledged Collateral owned or held by the Pledgors.

          SECTION 4.10. Insurance. In the event that the proceeds of any
insurance claim are paid after the Administrative Agent has exercised its right
to foreclose after an Event of Default, such Net Cash Proceeds shall be paid to
the Administrative Agent to satisfy any deficiency remaining after such
foreclosure.

          SECTION 4.11. Payment of Taxes; Compliance with Laws; Contesting
Liens; Claims. Each Pledgor represents and warrants that all Claims imposed upon
or assessed against the Pledged Collateral have been paid and discharged except
to the extent such Claims constitute a Lien not yet due and payable which is a
Contested Lien or a Permitted Collateral Lien. Each Pledgor shall comply with
all Requirements of Law applicable to the Pledged Collateral the failure to
comply with which would, individually or in the aggregate, have a Material
Adverse Effect. Each Pledgor may at its own expense contest the validity, amount
or applicability of any Claims so long as the contest thereof shall be conducted
in accordance with, and permitted pursuant to the provisions of, the Credit
Agreement. Notwithstanding the foregoing provisions of this Section 4.11, (i) no
contest of any such obligation may be pursued by such Pledgor if such contest
would expose the Administrative Agent or any other Secured Party to (A) any
possible criminal liability or (B) any additional civil liability for failure to
comply with such obligations unless such Pledgor shall have furnished a bond or
other security therefor satisfactory to the Administrative Agent, or such
Secured Party, as the case may be and (ii) if at any time payment or performance
of any obligation contested by such Pledgor pursuant to this Section 4.11 shall
become necessary to prevent the imposition of remedies against the Pledged
Collateral because of non-payment, such Pledgor shall pay or perform the same in
sufficient time to prevent the imposition of remedies against the Pledged
Collateral in respect of such default or prospective default.

          SECTION 4.12. Access to Pledged Collateral, Books and Records; Other
Information. Upon reasonable request to each Pledgor, the Administrative Agent,
its agents, accountants and attorneys shall have full and free access to visit
and inspect, as applicable, during normal business hours and such other
reasonable times as may be requested by the Administrative Agent all of the
Pledged Collateral and Mortgaged Property including all of the books,
correspondence and records of such Pledgor relating thereto. The Administrative
Agent and its representatives may examine the same, take extracts therefrom and
make photocopies thereof, and such Pledgor agrees to render to the
Administrative Agent, at such Pledgor's cost and expense, such clerical and
other assistance as may be reasonably requested by the Administrative Agent with
regard thereto. Such Pledgor shall, at any and all times, within a reasonable
time after written request by the Administrative Agent, furnish or cause to be
furnished to the Administrative Agent, in such manner and in such detail as may
be reasonably requested by the Administrative Agent, additional information with
respect to the Pledged Collateral.

                                   ARTICLE V

               CERTAIN PROVISIONS CONCERNING SECURITIES COLLATERAL

          SECTION 5.1. Pledge of Additional Securities Collateral. Each Pledgor
shall, upon obtaining any Pledged Securities or Intercompany Notes of any
person, accept the same in trust for the benefit of the Administrative Agent and
forthwith deliver to the Administrative Agent a pledge amendment, duly executed
by such Pledgor, in substantially the form of Exhibit 2 annexed hereto (each, a
"Pledge Amendment"), and the certificates and other documents required under
Section 3.1 and Section 3.2 hereof in respect of the additional Pledged
Securities or Intercompany Notes which are to be pledged pursuant to this
Agreement, and confirming the attachment of the Lien hereby created on and in
respect of such additional Pledged Securities or Intercompany Notes. Each
Pledgor hereby authorizes the Administrative Agent to attach each Pledge
Amendment to this Agreement and agrees that all Pledged Securities or
Intercompany Notes listed on any Pledge Amendment delivered to the
Administrative Agent shall for all purposes hereunder be considered Pledged
Collateral.

          SECTION 5.2.  Voting Rights; Distributions; etc.

          (a)  So long as no Event of Default shall have occurred and be
continuing:

          (i)  Each Pledgor shall be entitled to exercise any and all voting
    and other consensual rights pertaining to the Securities Collateral or any
    part thereof for any purpose not inconsistent with the terms or purposes
    hereof, the Credit Agreement or any other document evidencing the
    Indebtedness; provided, however, that no Pledgor shall in any event exercise
    such rights in any manner which could reasonably be expected to have a
    Material Adverse Effect.

<PAGE>

                                      -24-

          (ii)  Each Pledgor shall be entitled to receive and retain, and to
    utilize free and clear of the Lien hereof, any and all Distributions, but
    only if and to the extent made in accordance with the provisions of the
    Credit Agreement; provided, however, that any and all such Distributions
    consisting of rights or interests in the form of securities shall be
    forthwith delivered to the Administrative Agent to hold as Pledged
    Collateral and shall, if received by any Pledgor, be received in trust for
    the benefit of the Administrative Agent, be segregated from the other
    property or funds of such Pledgor and be forthwith delivered to the
    Administrative Agent as Pledged Collateral in the same form as so received
    (with any necessary endorsement).

          (b)  The Administrative Agent shall be deemed without further
action or formality to have granted to each Pledgor all necessary consents
relating to voting rights and shall, if necessary, upon written request of any
Pledgor and at the sole cost and expense of the Pledgors, from time to time
execute and deliver (or cause to be executed and delivered) to such Pledgor all
such instruments as such Pledgor may reasonably request in order to permit such
Pledgor to exercise the voting and other rights which it is entitled to exercise
pursuant to Section 5.2(a)(i) hereof and to receive the Distributions which it
is authorized to receive and retain pursuant to Section 5.2(a)(ii) hereof.

          (c)   Upon the occurrence and during the continuance of any Event of
Default:

          (i)   All rights of each Pledgor to exercise the voting and other
    consensual rights it would otherwise be entitled to exercise pursuant to
    Section 5.2(a)(i) hereof shall cease, and all such rights shall thereupon
    become vested in the Administrative Agent, which shall thereupon have the
    sole right to exercise such voting and other consensual rights.

          (ii)  All rights of each Pledgor to receive Distributions which it
    would otherwise be authorized to receive and retain pursuant to Section
    5.2(a)(ii) hereof shall cease and all such rights shall thereupon become
    vested in the Administrative Agent, which shall thereupon have the sole
    right to receive and hold as Pledged Collateral such Distributions.

          (d)   Each Pledgor shall, at its sole cost and expense, from time to
time execute and deliver to the Administrative Agent appropriate instruments as
the Administrative Agent may request in order to permit the Administrative Agent
to exercise the voting and other rights which it may be entitled to exercise
pursuant to Section 5.2(a)(i) hereof and to receive all Distributions which it
may be entitled to receive under Section 5.2(a)(ii) hereof.

          (e)   All Distributions which are received by any Pledgor contrary to
the provisions of Section 5.2(a)(ii) hereof shall be received in trust for the
benefit of the Administrative Agent, shall be segregated from other funds of
such Pledgor and shall immediately be paid over to the Administrative Agent as
Pledged Collateral in the same form as so received (with any necessary
endorsement).

                                      -25-

          SECTION 5.3.  Defaults, etc. Such Pledgor is not in default in the
payment of any portion of any mandatory capital contribution, if any, required
to be made under any agreement to which such Pledgor is a party relating to the
Pledged Securities pledged by it, and such Pledgor is not in violation of any
other provisions of any such agreement to which such Pledgor is a party, or
otherwise in default or violation thereunder. No Securities Collateral pledged
by such Pledgor is subject to any defense, offset or counterclaim, nor have any
of the foregoing been asserted or alleged against such Pledgor by any person
with respect thereto, and as of the date hereof, there are no certificates,
instruments, documents or other writings (other than the Organizational
Documents and certificates, if any, delivered to the Administrative Agent) which
evidence any Pledged Securities of such Pledgor.

          SECTION 5.4.  Certain Agreements of Pledgors As Issuers and Holders
of Equity Interests.

          (a) In the case of each Pledgor which is an issuer of Securities
Collateral, such Pledgor agrees to be bound by the terms of this Agreement
relating to the Securities Collateral issued by it and will comply with such
terms insofar as such terms are applicable to it.

          (b) In the case of each Pledgor which is a partner in a
partnership, limited liability company or other entity, such Pledgor hereby
consents to the extent required by the applicable Organizational Document to the
pledge by each other Pledgor, pursuant to the terms hereof, of the Pledged
Interests in such partnership, limited liability company or other entity and,
upon the occurrence and during the continuance of an Event of Default, to the
transfer of such Pledged Interests to the Administrative Agent or its nominee
and to the substitution of the Administrative Agent or its nominee as a
substituted partner or member in such partnership, limited liability company or
other entity with all the rights, powers and duties of a general partner or a
limited partner or member, as the case may be.

                                   ARTICLE VI

                   CERTAIN PROVISIONS CONCERNING INTELLECTUAL
                               PROPERTY COLLATERAL

          SECTION 6.1. Grant of License. For the purpose of enabling the
Administrative Agent, during the continuance of an Event of Default, to exercise
rights and remedies under Article IX hereof at such time as the Administrative
Agent shall be lawfully entitled to exercise such rights and remedies, and for
no other purpose, each Pledgor hereby grants to the Administrative Agent, to the
extent assignable, an irrevocable, non-exclusive license to use, assign, license
or sublicense any of the Intellectual Property Collateral now owned or hereafter
acquired by such Pledgor, wherever the same may be located. Such license shall
include access to all media in which any of the licensed items may be recorded
or stored and to all computer programs used for the compilation or printout
hereof.

<PAGE>

                                      -26-

          SECTION 6.2. Protection of Administrative Agent's Security. On a
continuing basis, each Pledgor shall, at its sole cost and expense, (i) promptly
following its becoming aware thereof, notify the Administrative Agent of (A) any
materially adverse determination in any proceeding in the United States Patent
and Trademark Office or the United States Copyright Office with respect to any
material Patent, Trademark or Copyright or (B) the institution of any proceeding
or any adverse determination in any federal, state or local court or
administrative body regarding such Pledgor's claim of ownership in or right to
use any of the Intellectual Property Collateral material to the use and
operation of the Pledged Collateral or Mortgaged Property, its right to register
such Intellectual Property Collateral or its right to keep and maintain such
registration in full force and effect, (ii) maintain and protect the
Intellectual Property Collateral material to the use and operation of the
Pledged Collateral or Mortgaged Property as presently used and operated and as
contemplated by the Credit Agreement, (iii) not permit to lapse or become
abandoned any Intellectual Property Collateral material to the use and operation
of the Pledged Collateral or Mortgaged Property as presently used and operated
and as contemplated by the Credit Agreement, and not settle or compromise any
pending or future litigation or administrative proceeding with respect to such
Intellectual Property Collateral, in each case except as shall be consistent
with commercially reasonable business judgment, (iv) upon such Pledgor obtaining
knowledge thereof, promptly notify the Administrative Agent in writing of any
event which may be reasonably expected to materially and adversely affect the
value or utility of the Intellectual Property Collateral or any portion thereof
material to the use and operation of the Pledged Collateral or Mortgaged
Property, the ability of such Pledgor or the Administrative Agent to dispose of
the Intellectual Property Collateral or any portion thereof or the rights and
remedies of the Administrative Agent in relation thereto including a levy or
threat of levy or any legal process against the Intellectual Property Collateral
or any portion thereof, (v) not license the Intellectual Property Collateral
other than licenses entered into by such Pledgor in, or incidental to, the
ordinary course of business, or amend or permit the amendment of any of the
licenses in a manner that materially and adversely affects the right to receive
payments thereunder, or in any manner that would materially impair the value of
the Intellectual Property Collateral or the Lien on and security interest in the
Intellectual Property Collateral intended to be granted to the Administrative
Agent for the benefit of the Secured Parties, without the consent of the
Administrative Agent, (vi) diligently keep adequate records respecting the
Intellectual Property Collateral and (vii) furnish to the Administrative Agent
from time to time upon the Administrative Agent's request therefor reasonably
detailed statements and amended schedules further identifying and describing the
Intellectual Property Collateral and such other materials evidencing or reports
pertaining to the Intellectual Property Collateral as the Administrative Agent
may from time to time request.

          SECTION 6.3. After-Acquired Property. If any Pledgor shall, at
any time before the Indebtedness have been paid in full (other than contingent
indemnification obligations which, pursuant to the provisions of the Credit
Agreement or the Security Instruments, survive the termination thereof), (i)
obtain any rights to any additional Intellectual Property Collateral or (ii)
become entitled to the benefit of any additional Intellectual Property
Collateral or any renewal or extension thereof, including any reissue, division,
continuation, or continuation-in-part of any Intellectual Property Collateral,
or any improvement on any Intellectual Property Collat-

<PAGE>

                                      -27-

eral, the provisions hereof shall automatically apply thereto and any such item
enumerated in clause (i) or (ii) of this Section 6.3 with respect to such
Pledgor shall automatically constitute Intellectual Property Collateral if such
would have constituted Intellectual Property Collateral at the time of execution
hereof and be subject to the Lien and security interest created by this
Agreement without further action by any party. Each Pledgor shall promptly (i)
provide to the Administrative Agent written notice of any of the foregoing and
(ii) confirm the attachment of the Lien and security interest created by this
Agreement to any rights described in clauses (i) and (ii) of the immediately
preceding sentence of this Section 6.3 by execution of an instrument in form
reasonably acceptable to the Administrative Agent and the filing of any
instruments or statements as shall be reasonably necessary to preserve, protect
or perfect the Administrative Agent's security interest in such Intellectual
Property Collateral. Further, each Pledgor authorizes the Administrative Agent
to modify this Agreement by amending Schedules 14(a) and 14(b) annexed to the
Perfection Certificate to include any Intellectual Property Collateral acquired
or arising after the date hereof of such Pledgor.

          SECTION 6.4. Litigation. Unless there shall occur and be
continuing any Event of Default, each Pledgor shall have the right to commence
and prosecute in its own name, as the party in interest, for its own benefit and
at the sole cost and expense of the Pledgors, such applications for protection
of the Intellectual Property Collateral and suits, proceedings or other actions
to prevent the infringement, counterfeiting, unfair competition, dilution,
diminution in value or other damage as are necessary to protect the Intellectual
Property Collateral. Upon the occurrence and during the continuance of any Event
of Default, the Administrative Agent shall have the right but shall in no way be
obligated to file applications for protection of the Intellectual Property
Collateral and/or bring suit in the name of any Pledgor, the Administrative
Agent or the Secured Parties to enforce the Intellectual Property Collateral and
any license thereunder. In the event of such suit, each Pledgor shall, at the
reasonable request of the Administrative Agent, do any and all lawful acts and
execute any and all documents requested by the Administrative Agent in aid of
such enforcement and the Pledgors shall promptly reimburse and indemnify the
Administrative Agent for all costs and expenses incurred by the Administrative
Agent in the exercise of its rights under this Section 6.4 in accordance with
Section 12.03 of the Credit Agreement. In the event that the Administrative
Agent shall elect not to bring suit to enforce the Intellectual Property
Collateral, each Pledgor agrees, at the reasonable request of the Administrative
Agent, to take all commercially reasonable actions necessary, whether by suit,
proceeding or other action, to prevent the infringement, counterfeiting, unfair
competition, dilution, diminution in value of or other damage to any of the
Intellectual Property Collateral by others and for that purpose agrees to
diligently maintain any suit, proceeding or other action against any person so
infringing necessary to prevent such infringement.

manner consistent with prudent business practice, including records of all
payments received, all credits granted thereon, all merchandise returned and all
other documentation relating thereto. Each Pledgor shall, at such Pledgor's sole
cost and expense, upon the Administrative Agent's demand made at any time after
the occurrence and during the continuance of any Event of Default, deliver all
tangible evidence of Accounts, including all documents evidencing Accounts and
any books and records relating thereto to the Administrative Agent or to its
representatives (copies of which evidence and books and records may be retained
by such Pledgor). Upon the occurrence and during the continuance of any Event of
Default, the Administrative Agent may transfer a full and complete copy of any
Pledgor's books, records, credit information, reports, memoranda and all other
writings relating to the Accounts to and for the use by any person that has
acquired or is contemplating acquisition of an interest in the Accounts or the
Administrative Agent's security interest therein without the consent of any
Pledgor.

modify any term thereof or make any adjustment with respect thereto except in
the ordinary course of business consistent with prudent business practice, or
extend or renew any such obligations except in the ordinary course of business
consistent with prudent business practice or compromise or settle any dispute,
claim, suit or legal proceeding relating thereto or sell any Account or interest
therein except in the ordinary course of business consistent with prudent
business practice without the prior written consent of the Administrative Agent.
Each Pledgor shall timely fulfill all obligations on its part to be fulfilled
under or in connection with the Accounts except where failure would not have a
Material Adverse Effect.

          SECTION 7.4. Collection. Each Pledgor shall use commercially
reasonable efforts to collect from the Account Debtor of each of the Accounts,
as and when due in the ordinary course of business and consistent with prudent
business practice (including Accounts that are delinquent, such Accounts to be
collected in accordance with generally accepted commercial collection
procedures), any and all amounts owing under or on account of such Account, and
apply forthwith upon receipt thereof all such amounts as are so collected to the
outstanding balance of such Account, except that any Pledgor may, with respect
to an Account, allow in the ordinary course of business (i) a refund or credit
due as a result of returned or damaged or defective merchandise and (ii) such
extensions of time to pay amounts due in respect of Accounts and such other
modifications of payment terms or settlements in respect of Accounts as shall be
commercially reasonable in the circumstances, all in accordance with such
Pledgor's ordinary course of business consistent with its collection practices
as in effect from time to time. The costs and ex-

penses (including attorneys' fees) of collection, in any case, whether incurred
by any Pledgor, the Administrative Agent or any Secured Party, shall be paid by
the Pledgors.

                                    TRANSFERS

          SECTION 8.1. Transfers of Pledged Collateral. No Pledgor shall sell,
convey, assign or otherwise dispose of, or grant any option with respect to, any
of the Pledged Collateral pledged by it hereunder except as permitted by the
Credit Agreement.

                                   ARTICLE IX

                                    REMEDIES

          SECTION 9.1. Remedies. Upon the occurrence and during the continuance
of any Event of Default the Administrative Agent may from time to time exercise
in respect of the Pledged Collateral, in addition to the other rights and
remedies provided for herein or otherwise available to it, the following
remedies:

          (a) Personally, or by agents or attorneys, immediately take
possession of the Pledged Collateral or any part thereof, from any Pledgor or
any other person who then has possession of any part thereof with or without
notice or process of law, and for that purpose may enter upon any Pledgor's
premises where any of the Pledged Collateral is located, remove such Pledged
Collateral, remain present at such premises to receive copies of all
communications and remittances relating to the Pledged Collateral and use in
connection with such removal and possession any and all services, supplies, aids
and other facilities of any Pledgor;

          (b) Demand, sue for, collect or receive any money or property at any
time payable or receivable in respect of the Pledged Collateral including
instructing the obligor or obligors on any agreement, instrument or other
obligation constituting part of the Pledged Collateral to make any payment
required by the terms of such agreement, instrument or other obligation directly
to the Administrative Agent, and in connection with any of the foregoing,
compromise, settle, extend the time for payment and make other modifications
with respect thereto; provided, however, that in the event that any such
payments are made directly to any Pledgor, prior to receipt by any such obligor
of such instruction, such Pledgor shall segregate all amounts received pursuant
thereto in trust for the benefit of the Administrative Agent and shall promptly
(but in no event later than one (1) Business Day after receipt thereof) pay such
amounts to the Administrative Agent;

<PAGE>

                                      -30-

          (c) Sell, assign, grant a license to use or otherwise liquidate,
or direct any Pledgor to sell, assign, grant a license to use or otherwise
liquidate, any and all investments made in whole or in part with the Pledged
Collateral or any part thereof, and take possession of the proceeds of any such
sale, assignment, license or liquidation;

          (d) Take possession of the Pledged Collateral or any part thereof, by
directing any Pledgor in writing to deliver the same to the Administrative Agent
at any place or places so designated by the Administrative Agent, in which event
such Pledgor shall at its own expense: (A) forthwith cause the same to be moved
to the place or places designated by the Administrative Agent and therewith
delivered to the Administrative Agent, (B) store and keep any Pledged Collateral
so delivered to the Administrative Agent at such place or places pending further
action by the Administrative Agent and (C) while the Pledged Collateral shall be
so stored and kept, provide such security and maintenance services as shall be
necessary to protect the same and to preserve and maintain them in good
condition. Each Pledgor's obligation to deliver the Pledged Collateral as
contemplated in this Section 9.1(iv) is of the essence hereof. Upon application
to a court of equity having jurisdiction, the Administrative Agent shall be
entitled to a decree requiring specific performance by any Pledgor of such
obligation;

          (e) Withdraw all moneys, instruments, securities and other property
in any bank, financial securities, deposit or other account of any Pledgor
constituting Pledged Collateral for application to the Indebtedness as provided
in Article X hereof;

          (f) Retain and apply the Distributions to the Indebtedness as provided
in Article X hereof;

          (g) Exercise any and all rights as beneficial and legal owner of the
Pledged Collateral, including perfecting assignment of and exercising any and
all voting, consensual and other rights and powers with respect to any Pledged
Collateral; and

          (h) All the rights and remedies of a secured party on default under
the UCC, and the Administrative Agent may also in its sole discretion, without
notice except as specified in Section 9.2 hereof, sell, assign or grant a
license to use the Pledged Collateral or any part thereof in one or more parcels
at public or private sale, at any exchange, broker's board or at any of the
Administrative Agent's offices or elsewhere, for cash, on credit or for future
delivery, and at such price or prices and upon such other terms as the
Administrative Agent may deem commercially reasonable. The Administrative Agent
or any other Secured Party or any of their respective Affiliates may be the
purchaser, licensee, assignee or recipient of any or all of the Pledged
Collateral at any such sale (to the extent permitted by law) and shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Pledged Collateral sold, assigned
or licensed at such sale, to use and apply any of the Indebtedness owed to such
person as a credit on account of the purchase price of any Pledged Collateral
payable by such person at such sale. Each purchaser, assignee, licensee or
recipient at any such sale shall acquire the property sold, assigned or licensed
absolutely free from any claim or right on the part of any Pledgor, and each
Pledgor hereby waives, to the fullest extent permitted by law, all rights of
redemption, stay and/or appraisal which it now has or may at any time in the

<PAGE>

                                      -31-

future have under any rule of law or statute now existing or hereafter enacted.
The Administrative Agent shall not be obligated to make any sale of Pledged
Collateral regardless of notice of sale having been given. The Administrative
Agent may adjourn any public or private sale from time to time by announcement
at the time and place fixed therefor, and such sale may, without further notice,
be made at the time and place to which it was so adjourned. Each Pledgor hereby
waives, to the fullest extent permitted by law, any claims against the
Administrative Agent arising by reason of the fact that the price at which any
Pledged Collateral may have been sold, assigned or licensed at such a private
sale was less than the price which might have been obtained at a public sale,
even if the Administrative Agent accepts the first offer received and does not
offer such Pledged Collateral to more than one offeree.

          SECTION 9.2. Notice of Sale. Each Pledgor acknowledges and agrees
that, to the extent notice of sale or other disposition of Pledged Collateral
shall be required by law, ten (10) days' prior notice to such Pledgor of the
time and place of any public sale or of the time after which any private sale or
other intended disposition is to take place shall be commercially reasonable
notification of such matters. No notification need be given to any Pledgor if it
has signed, after the occurrence of an Event of Default, a statement renouncing
or modifying any right to notification of sale or other intended disposition.

          SECTION 9.3. Waiver of Notice and Claims. Each Pledgor hereby waives,
to the fullest extent permitted by applicable law, notice or judicial hearing in
connection with the Administrative Agent's taking possession or the
Administrative Agent's disposition of any of the Pledged Collateral, including
any and all prior notice and hearing for any prejudgment remedy or remedies and
any such right which such Pledgor would otherwise have under law, and each
Pledgor hereby further waives, to the fullest extent permitted by applicable
law: (i) all damages occasioned by such taking of possession, (ii) all other
requirements as to the time, place and terms of sale or other requirements with
respect to the enforcement of the Administrative Agent's rights hereunder and
(iii) all rights of redemption, appraisal, valuation, stay, extension or
moratorium now or hereafter in force under any applicable law. The
Administrative Agent shall not be liable for any incorrect or improper payment
made pursuant to this Article IX in the absence of gross negligence or willful
misconduct. Any sale of, or the grant of options to purchase, or any other
realization upon, any Pledged Collateral shall operate to divest all right,
title, interest, claim and demand, either at law or in equity, of the applicable
Pledgor therein and thereto, and shall be a perpetual bar both at law and in
equity against such Pledgor and against any and all persons claiming or
attempting to claim the Pledged Collateral so sold, optioned or realized upon,
or any part thereof, from, through or under such Pledgor.

          SECTION 9.4.    Certain Sales of Pledged Collateral.

          (a)  Each Pledgor recognizes that, by reason of certain prohibitions
contained in law, rules, regulations or orders of any Governmental Authority,
the Administrative Agent may be compelled, with respect to any sale of all or
any part of the Pledged Collateral, to limit purchasers to those who meet the
requirements of such Governmental Authority. Each Pledgor acknowledges that any
such sales may be at prices and on terms less favorable to the Administrative
Agent than those obtainable through a public sale without such restrictions,
and, notwith-

<PAGE>

                                      -32-

standing such circumstances, agrees that any such restricted sale shall be
deemed to have been made in a commercially reasonable manner and that, except as
may be required by applicable law, the Administrative Agent shall have no
obligation to engage in public sales.

          (b)  Each Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act, and applicable state securities laws, the
Administrative Agent may be compelled, with respect to any sale of all or any
part of the Securities Collateral and Investment Property, to limit purchasers
to persons who will agree, among other things, to acquire such Securities
Collateral or Investment Property for their own account, for investment and not
with a view to the distribution or resale thereof. Each Pledgor acknowledges
that any such private sales may be at prices and on terms less favorable to the
Administrative Agent than those obtainable through a public sale without such
restrictions (including a public offering made pursuant to a registration
statement under the Securities Act), and, notwithstanding such circumstances,
agrees that any such private sale shall be deemed to have been made in a
commercially reasonable manner and that the Administrative Agent shall have no
obligation to engage in public sales and no obligation to delay the sale of any
Securities Collateral or Investment Property for the period of time necessary to
permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would agree to do so.

          (c)  Notwithstanding the foregoing, each Pledgor shall, upon the
occurrence and during the continuance of any Event of Default, at the reasonable
request of the Administrative Agent, for the benefit of the Administrative
Agent, cause any registration, qualification under or compliance with any
Federal or state securities law or laws to be effected with respect to all or
any part of the Securities Collateral as soon as practicable and at the sole
cost and expense of the Pledgors. Each Pledgor will use its commercially
reasonable efforts to cause such registration to be effected (and be kept
effective) and will use its commercially reasonable efforts to cause such
qualification and compliance to be effected (and be kept effective) as may be so
requested and as would permit or facilitate the sale and distribution of such
Securities Collateral including registration under the Securities Act (or any
similar statute then in effect), appropriate qualifications under applicable
blue sky or other state securities laws and appropriate compliance with all
other requirements of any Governmental Authority. Each Pledgor shall use its
commercially reasonable efforts to cause the Administrative Agent to be kept
advised in writing as to the progress of each such registration, qualification
or compliance and as to the completion thereof, shall furnish to the
Administrative Agent such number of prospectuses, offering circulars or other
documents incident thereto as the Administrative Agent from time to time may
request, and shall indemnify and shall cause the issuer of the Securities
Collateral to indemnify the Administrative Agent and all others participating in
the distribution of such Securities Collateral against all claims, losses,
damages and liabilities caused by any untrue statement (or alleged untrue
statement) of a material fact contained therein (or in any related registration
statement, notification or the like) or by any omission (or alleged omission) to
state therein (or in any related registration statement, notification or the
like) a material fact required to be stated therein or necessary to make the
statements therein not misleading.

<PAGE>

                                      -33-

          (d)  If the Administrative Agent determines to exercise its right to
sell any or all of the Securities Collateral or Investment Property, upon
written request, the applicable Pledgor shall from time to time furnish to the
Administrative Agent all such information as the Administrative Agent may
request in order to determine the number of securities included in the
Securities Collateral or Investment Property which may be sold by the
Administrative Agent as exempt transactions under the Securities Act and the
rules of the Securities and Exchange Commission thereunder, as the same are from
time to time in effect.

          (e)  Each Pledgor further agrees that a breach of any of the covenants
contained in this Section 9.4 will cause irreparable injury to the
Administrative Agent and other Secured Parties, that the Administrative Agent
and the other 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 9.4 shall be specifically enforceable against such Pledgor, and such
Pledgor 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 and is continuing.

          SECTION 9.5.  No Waiver; Cumulative Remedies.

          (a)  No failure on the part of the Administrative Agent to exercise,
no course of dealing with respect to, and no delay on the part of the
Administrative Agent in exercising, any right, power or remedy hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
such right, power or remedy hereunder preclude any other or further exercise
thereof or the exercise of any other right, power or remedy; nor shall the
Administrative Agent be required to look first to, enforce or exhaust any other
security, collateral or guaranties. The remedies herein provided are cumulative
and are not exclusive of any remedies provided by law.

          (b)  In the event that the Administrative Agent shall have instituted
any proceeding to enforce any right, power or remedy under this Agreement by
foreclosure, sale, entry or otherwise, and such proceeding shall have been
discontinued or abandoned for any reason or shall have been determined adversely
to the Administrative Agent, then and in every such case, the Pledgors, the
Administrative Agent and each other Secured Party shall be restored to their
respective former positions and rights hereunder with respect to the Pledged
Collateral, and all rights, remedies and powers of the Administrative Agent and
the other Secured Parties shall continue as if no such proceeding had been
instituted.

          SECTION 9.6.  Certain Additional Actions Regarding Intellectual
Property. If any Event of Default shall have occurred and be continuing, upon
the written demand of the Administrative Agent, each Pledgor shall execute and
deliver to the Administrative Agent an assignment or assignments of the
registered Patents, Trademarks and/or Copyrights and Goodwill and such other
documents as are necessary or appropriate to carry out the intent and purposes
hereof. Within five (5) Business Days of written notice thereafter from the
Administrative Agent, each Pledgor shall make available to the Administrative
Agent, to the extent within such Pledgor's power and authority, such personnel
in such Pledgor's employ on the date of the Event of Default as the
Administrative Agent may reasonably designate to permit such Pledgor to con-

<PAGE>

                                      -34-

tinue, directly or indirectly, to produce, advertise and sell the products and
services sold by such Pledgor under the registered Patents, Trademarks and/or
Copyrights, and such persons shall be available to perform their prior functions
on the Administrative Agent's behalf.

                            APPLICATION OF PROCEEDS

          SECTION 10.1. Proceeds of Casualty Events and Collateral Dispositions.
The Pledgors shall take all actions required by the Credit Agreement with
respect to any Net Cash Proceeds of any Casualty Event or from the sale or
disposition of any Pledged Collateral.

          SECTION 10.2. Application of Proceeds. The proceeds received by the
Administrative Agent in respect of any sale of, collection from or other
realization upon all or any part of the Collateral pursuant to the exercise by
the Administrative Agent of its remedies shall be applied, together with any
other sums then held by the Administrative Agent pursuant to this Agreement, in
accordance with the Credit Agreement.

                                   ARTICLE XI

                                  MISCELLANEOUS

          SECTION 11.1.  Concerning Administrative Agent.

          (a)  The Administrative Agent has been appointed as collateral
agent pursuant to the Credit Agreement. The actions of the Administrative Agent
hereunder are subject to the provisions of the Credit Agreement. The
Administrative Agent shall have the right hereunder to make demands, to give
notices, to exercise or refrain from exercising any rights, and to take or
refrain from taking action (including the release or substitution of the Pledged
Collateral), in accordance with this Agreement and the Credit Agreement. The
Administrative Agent may employ agents and attorneys-in-fact in connection
herewith and shall not be liable for the negligence or misconduct of any such
agents or attorneys-in-fact selected by it in good faith. The Administrative
Agent may resign and a successor Administrative Agent may be appointed in the
manner provided in the Credit Agreement. Upon the acceptance of any appointment
as the Administrative Agent by a successor Administrative Agent, that successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent under
this Agreement, and the retiring Administrative Agent shall thereupon be
discharged from its duties and obligations under this Agreement. After any
retiring Administrative Agent's resignation, the provisions hereof shall inure
to its benefit as to

<PAGE>

                                      -35-

any actions taken or omitted to be taken by it under this Agreement while it was
the Administrative Agent.

          (b)  The Administrative Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Pledged Collateral in its
possession if such Pledged Collateral is accorded treatment substantially
equivalent to that which the Administrative Agent, in its individual capacity,
accords its own property consisting of similar instruments or interests, it
being understood that neither the Administrative Agent nor any of the Secured
Parties shall have responsibility for (i) ascertaining or taking action with
respect to calls, conversions, exchanges, maturities, tenders or other matters
relating to any Securities Collateral, whether or not the Administrative Agent
or any other Secured Party has or is deemed to have knowledge of such matters or
(ii) taking any necessary steps to preserve rights against any person with
respect to any Pledged Collateral.

          (c) The Administrative Agent shall be entitled to rely upon any
written notice, statement, certificate, order or other document or any telephone
message believed by it to be genuine and correct and to have been signed, sent
or made by the proper person, and, with respect to all matters pertaining to
this Agreement and its duties hereunder, upon advice of counsel selected by it.

          (d) If any item of Pledged Collateral also constitutes collateral
granted to the Administrative Agent under any other deed of trust, mortgage,
security agreement, pledge or instrument of any type, in the event of any
conflict between the provisions hereof and the provisions of such other deed of
trust, mortgage, security agreement, pledge or instrument of any type in respect
of such collateral, the Administrative Agent, in its sole discretion, shall
select which provision or provisions shall control.

          SECTION 11.2. Administrative Agent May Perform; Administrative Agent
Appointed Attorney-in-Fact. If any Pledgor shall fail to perform any covenants
contained in this Agreement (including such Pledgor's covenants to (i) pay the
premiums in respect of all required insurance policies hereunder, (ii) pay
Claims, (iii) make repairs, (iv) discharge Liens or (v) pay or perform any
obligations of such Pledgor under any Pledged Collateral) or if any
representation or warranty on the part of any Pledgor contained herein shall be
breached, the Administrative Agent may (but shall not be obligated to) do the
same or cause it to be done or remedy any such breach, and may expend funds for
such purpose; provided, however, that the Administrative Agent shall in no event
be bound to inquire into the validity of any tax, lien, imposition or other
obligation which such Pledgor fails to pay or perform as and when required
hereby and which such Pledgor does not contest in accordance in accordance with
the provisions of Section 4.11 hereof. Any and all amounts so expended by the
Administrative Agent shall be paid by the Pledgors in accordance with the
provisions of Section 12.03 of the Credit Agreement. Neither the provisions of
this Section 11.2 nor any action taken by the Administrative Agent pursuant to
the provisions of this Section 11.2 shall prevent any such failure to observe
any covenant contained in this Agreement nor any breach of representation or
warranty from constituting an Event of Default. Each Pledgor hereby appoints the
Administrative Agent its attorney-in-fact, with full authority in the place and
stead of such Pledgor and in the name of such Pledgor, or otherwise,

<PAGE>

                                      -36-

from time to time in the Administrative Agent's discretion to take any action
and to execute any instrument consistent with the terms of the Credit Agreement,
this Agreement and the other Security Instruments which the Administrative Agent
may deem necessary or advisable to accomplish the purposes hereof if any Pledgor
shall fail to perform any covenants or agreements contained in this Agreement.
The foregoing grant of authority is a power of attorney coupled with an interest
and such appointment shall be irrevocable for the term hereof. Each Pledgor
hereby ratifies all that such attorney shall lawfully do or cause to be done by
virtue hereof.

          SECTION 11.3. Continuing Security Interest; Assignment. This Agreement
shall create a continuing security interest in the Pledged Collateral and shall
(i) be binding upon the Pledgors, their respective successors and assigns and
(ii) inure, together with the rights and remedies of the Administrative Agent
hereunder, to the benefit of the Administrative Agent and the other Secured
Parties and each of their respective successors, transferees and assigns. No
other persons (including any other creditor of any Pledgor) shall have any
interest herein or any right or benefit with respect hereto. Without limiting
the generality of the foregoing clause (ii), any Secured Party may assign or
otherwise transfer any indebtedness held by it secured by this Agreement to any
other person, and such other person shall thereupon become vested with all the
benefits in respect thereof granted to such Secured Party, herein or otherwise,
subject however, to the provisions of the Credit Agreement and any Swap
Agreement.

          SECTION 11.4. Termination; Release. The Pledged Collateral shall be
released from the Lien of this Agreement in accordance with the provisions of
the Credit Agreement. Upon termination hereof or any release of Pledged
Collateral in accordance with the provisions of the Credit Agreement, the
Administrative Agent shall, upon the request and at the sole cost and expense of
the Pledgors, assign, transfer and deliver to Pledgor, against receipt and
without recourse to or warranty by the Administrative Agent except as to the
fact that the Administrative Agent has not encumbered the released assets, such
of the Pledged Collateral to be released (in the case of a release) as may be in
possession of the Administrative Agent and as shall not have been sold or
otherwise applied pursuant to the terms hereof, and, with respect to any other
Pledged Collateral, proper documents and instruments (including UCC-3
termination statements or releases) acknowledging the termination hereof or the
release of such Pledged Collateral, as the case may be.

          SECTION 11.5. Modification in Writing. No amendment, modification,
supplement, termination or waiver of or to any provision hereof, nor consent to
any departure by any Pledgor therefrom, shall be effective unless the same shall
be made in accordance with the terms of the Credit Agreement and unless in
writing and signed by the Administrative Agent. Any amendment, modification or
supplement of or to any provision hereof, any waiver of any provision hereof and
any consent to any departure by any Pledgor from the terms of any provision
hereof shall be effective only in the specific instance and for the specific
purpose for which made or given. Except where notice is specifically required by
this Agreement or any other document evidencing the Indebtedness, no notice to
or demand on any Pledgor in any case shall entitle any Pledgor to any other or
further notice or demand in similar or other circumstances.

<PAGE>

                                      -37-

          SECTION 11.6  Notices. Unless otherwise provided herein or in the
Credit Agreement, any notice or other communication herein required or permitted
to be given shall be given in the manner and become effective as set forth in
the Credit Agreement, as to any Pledgor, addressed to it at the address of the
Borrowers set forth in the Credit Agreement and as to the Administrative Agent,
addressed to it at the address set forth in the Credit Agreement, or in each
case at such other address as shall be designated by such party in a written
notice to the other party complying as to delivery with the terms of this
Section 11.6.

          SECTION 11.7. Governing Law, Consent to Jurisdiction and Service of
Process; Waiver of Jury Trial. Section 12.09 of the Credit Agreement is
incorporated herein, mutatis mutandis, as if a part hereof.

          SECTION 11.8. Severability of Provisions. Any provision hereof 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 or
affecting the validity or enforceability of such provision in any other
jurisdiction.

          SECTION 11.9. Execution in Counterparts. This Agreement and any
amendments, waivers, consents or supplements hereto may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original,
but all such counterparts together shall constitute one and the same agreement.

          SECTION 11.10. Business Days. In the event any time period or any date
provided in this Agreement ends or falls on a day other than a Business Day,
then such time period shall be deemed to end and such date shall be deemed to
fall on the next succeeding Business Day, and performance herein may be made on
such Business Day, with the same force and effect as if made on such other day.

          SECTION 11.11. Waiver of Stay. Each Pledgor covenants (to the extent
it may lawfully do so) that in the event that such Pledgor or any property or
assets of such Pledgor shall hereafter become the subject of a voluntary or
involuntary proceeding under the Bankruptcy Code or such Pledgor shall otherwise
be a party to any federal or state bankruptcy, insolvency, moratorium or similar
proceeding to which the provisions relating to the automatic stay under Section
362 of the Bankruptcy Code or any similar provision in any such law is
applicable, then, in any such case, whether or not the Administrative Agent has
commenced foreclosure proceedings under this Agreement, such Pledgor shall not,
and each Pledgor hereby expressly waives their right to (to the extent it may
lawfully do so) at any time insist upon, plead or in any whatsoever, claim or
take the benefit or advantage of any such automatic stay or such similar
provision as it relates to the exercise of any of the rights and remedies
(including any foreclosure proceedings) available to the Administrative Agent as
provided in this Agreement, in any other Security Instrument or any other
document evidencing the Indebtedness. Each Pledgor further covenants (to the
extent it may lawfully do so) that it will not hinder, delay or impede the
execution of any power granted herein to the Administrative Agent, but will
suffer and permit the execution of every such power as though no law relating to
any stay or similar provision had been enacted.

<PAGE>

                                      -38-

          SECTION 11.12. No Credit for Payment of Taxes or Imposition. Such
Pledgor shall not be entitled to any credit against the principal, premium, if
any, or interest payable under the Credit Agreement, and such Pledgor shall not
be entitled to any credit against any other sums which may become payable under
the terms thereof or hereof, by reason of the payment of any Tax on the Pledged
Collateral or any part thereof.

          SECTION 11.13. No Claims Against Administrative Agent. Nothing
contained in this Agreement shall constitute any consent or request by the
Administrative Agent, express or implied, for the performance of any labor or
services or the furnishing of any materials or other property in respect of the
Pledged Collateral or any part thereof, nor as giving any Pledgor any right,
power or authority to contract for or permit the performance of any labor or
services or the furnishing of any materials or other property in such fashion as
would permit the making of any claim against the Administrative Agent in respect
thereof or any claim that any Lien based on the performance of such labor or
services or the furnishing of any such materials or other property is prior to
the Lien hereof.

          SECTION 11.14. No Release. Nothing set forth in this Agreement shall
relieve any Pledgor from the performance of any term, covenant, condition or
agreement on such Pledgor's part to be performed or observed under or in respect
of any of the Pledged Collateral or from any liability to any person under or in
respect of any of the Pledged Collateral or shall impose any obligation on the
Administrative Agent or any other Secured Party to perform or observe any such
term, covenant, condition or agreement on such Pledgor's part to be so performed
or observed or shall impose any liability on the Administrative Agent or any
other Secured Party for any act or omission on the part of such Pledgor relating
thereto or for any breach of any representation or warranty on the part of such
Pledgor contained in this Agreement, the Credit Agreement or the other Loan
Documents, or under or in respect of the Pledged Collateral or made in
connection herewith or therewith. The obligations of each Pledgor contained in
this Section 11.14 shall survive the termination hereof and the discharge of
such Pledgor's other obligations under this Agreement, the Credit Agreement and
the other Loan Documents.

          SECTION 11.15.  Indebtedness Absolute. All obligations of each Pledgor
hereunder shall be absolute and unconditional irrespective of:

          (a)  any bankruptcy, insolvency, reorganization, arrangement,
