not such Liens are Permitted Liens) and which Lien or trust, in the reasonable
determination of the Agents or the Required Lenders (from the perspective of an
asset-based lender), has a reasonable possibility of having a priority superior
to the Collateral Agent's Liens (such as landlord liens, ad valorem taxes,
production taxes, severance taxes, sales taxes, collections attributable to sale

to such item of Collateral, proceeds or collection; (C) estimates of present and
future costs, expenses, deposits and liabilities related to the plugging and
abandonment of the Oil and Gas Properties (net of the amount thereof which has

any Agent may impose as a result of non-compliance with Section 7.01(g) by any
owner or operator of the Oil and Gas Properties of the Borrower. The Borrower

including all Capitalized Lease Obligations paid, payable or incurred during
such period (without duplication of any amounts paid, payable or incurred in any
prior period), and (ii) to the extent not covered by clause (i) above, the

period to acquire by purchase or otherwise the business or fixed assets of, or
the Capital Stock of, any other Person.

          Section 2.02    Making the Loans . (a) The Borrower shall give the
Funding Agent prior telephonic notice (immediately confirmed in writing, in
substantially the form of Exhibit D hereto (a "Notice of Borrowing")), not later
than 12:00 noon (New York City time) on the date which is two (2) Business Days
prior to the date of the proposed Loan (or such shorter period as the Funding
Agent is willing to accommodate from time to time, but in no event later than
12:00 noon (New York City time) on the borrowing date of the proposed Loan).
Such Notice of Borrowing shall be irrevocable and shall specify (i) the
principal amount of the proposed Loan, (ii) the use of the proceeds of such
proposed Loan, (iii) whether such Loan is a Revolving A Loan, a Revolving B Loan
or a Revolving C Loan, and (iv) the proposed borrowing date, which must be a
Business Day. The Funding Agent and the Lenders may act without liability upon
the basis of written, telecopied or telephonic notice believed by the Funding
Agent in good faith to be from the Borrower (or from any Authorized Officer
thereof designated in writing purportedly from the Borrower to the Funding
Agent). The Borrower hereby waives the right to dispute the Funding Agent's
record of the terms of any such telephonic Notice of Borrowing. The Funding
Agent and each Lender shall be entitled to rely conclusively on any Authorized
Officer's authority to request a Loan on behalf of the Borrower until the
Funding Agent receives written notice to the contrary. The Funding Agent and the
Lenders shall have no duty to verify the authenticity of the signature appearing
on any written Notice of Borrowing.

               (b)  Each Notice of Borrowing pursuant to this Section 2.02 shall
be irrevocable and the Borrower shall be bound to make a borrowing in accordance
therewith. Each Revolving Loan shall be made in a minimum amount of $1,000,000
and shall be in an integral multiple of $1,000,000.

               (c)  (i)    Except as otherwise provided in this subsection
2.02(c), all Loans under this Agreement shall be made by the Lenders
simultaneously and proportionately to their Pro Rata Shares of the Total
Revolving A Credit Commitment, the Total Revolving B Credit Commitment and the
Total Revolving C Credit Commitment, as the case may be, it being understood
that no Lender shall be responsible for any default by any other Lender in that
other Lender's obligations to make a Loan requested hereunder, nor shall the
Commitment of any Lender be increased or decreased as a result of the default by
any other Lender in that other Lender's obligation to make a Loan requested
hereunder, and each Lender shall be obligated to make the Loans required to be
made by it by the terms of this Agreement regardless of the failure by any other
Lender.

                    (ii)   Notwithstanding any other provision of this
Agreement, and in order to reduce the number of fund transfers among the
Borrower, the Agents and the Lenders, the Borrower, the Agents and the Lenders
agree that the Funding Agent may (but shall not be obligated to), and the
Borrower and the Lenders hereby irrevocably authorize the Funding Agent to,
fund, on behalf of the Revolving Loan Lenders, Revolving Loans pursuant to
Section 2.01, subject to the procedures for settlement set forth in subsection
2.02(d); provided, however, that (a) the Funding Agent shall in no event fund
any such Revolving Loans if the Funding Agent shall have received written notice
from the Collateral Agent or the Required Lenders on the Business Day prior to
the date of the proposed Revolving Loan that one or more of the

                                     - 32 -

<PAGE>

conditions precedent contained in Section 5.02. will not be satisfied at the
time of the proposed Revolving Loan, and (b) the Funding Agent shall not
otherwise be required to determine that, or take notice whether, the conditions
precedent in Section 5.02 have been satisfied. If the Borrower gives a Notice of
Borrowing requesting a Revolving Loan and the Funding Agent elects not, or is
not permitted, to fund such Revolving Loan on behalf of the Revolving Loan
Lenders, then promptly after receipt of the Notice of Borrowing requesting such
Revolving Loan, the Funding Agent shall notify each Revolving Loan Lender of the
specifics of the requested Revolving Loan and that it will not fund, or is not
permitted to fund, the requested Revolving Loan on behalf of the Revolving Loan
Lenders. If the Funding Agent notifies the Revolving Loan Lenders that it will
not fund a requested Revolving Loan on behalf of the Revolving Loan Lenders,
each Revolving Loan Lender shall make its Pro Rata Share of the Revolving Loan
available to the Funding Agent, in immediately available funds, in the Funding
Agent's Account no later than 3:00 p.m. (New York City time) (provided that the
Funding Agent requests payment from such Revolving Loan Lender not later than
1:00 p.m. (New York City time)) on the date of the proposed Revolving Loan. The
Funding Agent will make the proceeds of such Revolving Loans available to the
Borrower on the day of the proposed Revolving Loan by causing an amount, in
immediately available funds, equal to the proceeds of all such Revolving Loans
received by the Funding Agent in the Funding Agent's Account or the amount
funded by the Funding Agent on behalf of the Revolving Loan Lenders to be
deposited in an account designated by the Borrower.

                    (iii)  If the Funding Agent has notified the Revolving Loan
Lenders that the Funding Agent, on behalf of the Revolving Loan Lenders, will
fund a particular Revolving Loan pursuant to subsection 2.02(c)(ii), the Funding
Agent may assume that each such Revolving Loan Lender has made such amount
available to the Funding Agent on such day and the Funding Agent, in its sole
discretion, may, but shall not be obligated to, cause a corresponding amount to
be made available to the Borrower on such day. If the Funding Agent makes such
corresponding amount available to the Borrower and such corresponding amount is
not in fact made available to the Funding Agent by any such Revolving Loan
Lender, the Funding Agent shall be entitled to recover such corresponding amount
on demand from such Revolving Loan Lender together with interest thereon, for
each day from the date such payment was due until the date such amount is paid
to the Funding Agent, at the Federal Funds Rate for three Business Days and
thereafter at the Reference Rate. During the period in which such Revolving Loan
Lender has not paid such corresponding amount to the Funding Agent,
notwithstanding anything to the contrary contained in this Agreement or any
other Loan Document, the amount so advanced by the Funding Agent to the Borrower
shall, for all purposes hereof, be a Revolving Loan made by the Funding Agent
for its own account. Upon any such failure by a Revolving Loan Lender to pay the
Funding Agent, the Funding Agent shall promptly thereafter notify the Borrower
of such failure and the Borrower shall immediately pay such corresponding amount
to the Funding Agent for its own account.

                    (iv)   Nothing in this subsection 2.02(c) shall be deemed to
relieve any Revolving Loan Lender from its obligations to fulfill its Revolving
Credit Commitment hereunder or to prejudice any rights that the Funding Agent or
the Borrower may have against any Revolving Loan Lender as a result of any
default by such Revolving Loan Lender hereunder.

               (d)  (i)    With respect to all periods for which the Funding
Agent has funded Revolving Loans pursuant to subsection 2.02(c), on Friday of
each week, or if the applicable Friday is not a Business Day, then on the
following Business Day, or such shorter period as the Funding Agent may from
time to time select (any such week or shorter period being herein called a
"Settlement Period"), the Funding Agent shall notify each Revolving Loan Lender
of the unpaid principal amount of the Revolving Loans outstanding as of the last
day of each such Settlement Period. In the event that such amount is greater
than the unpaid principal amount of the Revolving Loans outstanding on the last
day of the Settlement Period immediately preceding such Settlement Period (or,
if there has been no preceding Settlement Period, the amount of the Revolving
Loans made on the date of such Revolving Loan Lender's initial funding), each
Revolving Loan Lender shall promptly (and in any event not later than 2:00 p.m.
(New York City time) if the Funding Agent requests payment from such Lender not
later than 12:00 noon (New York City time) on such day) make available to the
Funding Agent its Pro Rata Share of the difference in immediately available
funds. In the event that such amount is less than such unpaid principal amount,
the Funding Agent shall promptly pay over to each Revolving Loan Lender its Pro
Rata Share of the difference in immediately available funds. In addition, if the
Funding Agent shall so request at any time when a Default or an Event of Default
shall have occurred and be continuing, or any other event shall have occurred as
a result of which the Funding Agent shall determine that it is desirable to
present claims against the Borrower for repayment, each Revolving Loan Lender
shall promptly remit to the Funding Agent or, as the case may be, the Funding
Agent shall promptly remit to each Revolving Loan Lender, sufficient funds to
adjust the interests of the Revolving Loan Lenders in the then outstanding
Revolving Loans to such an extent that, after giving effect to such adjustment,
each such Revolving Loan Lender's interest in the then outstanding Revolving
Loans will be equal to its Pro Rata Share thereof. The obligations of the
Funding Agent and each Revolving Loan Lender under this subsection 2.02(d) shall
be absolute and unconditional. Each Revolving Loan Lender shall only be entitled
to receive interest on its Pro Rata Share of the Revolving Loans which have been
funded by such Revolving Loan Lender.

                    (ii)   In the event that any Revolving Loan Lender fails to
make any payment required to be made by it pursuant to subsection 2.02(d)(i),
the Funding Agent shall be entitled to recover such corresponding amount on
demand from such Revolving Loan Lender together with interest thereon, for each
day from the date such payment was due until the date such amount is paid to the
Funding Agent, at the Federal Funds Rate for three Business Days and thereafter
at the Reference Rate. During the period in which such Revolving Loan Lender has
not paid such corresponding amount to the Funding Agent, notwithstanding
anything to the contrary contained in this Agreement or any other Loan Document,
the amount so advanced by the Funding Agent to the Borrower shall, for all
purposes hereof, be a Revolving Loan made by the Funding Agent for its own
account. Upon any such failure by a Revolving Loan Lender to pay the Funding
Agent, the Funding Agent shall promptly thereafter notify the Borrower of such
failure and the Borrower shall immediately pay such corresponding amount to the
Funding Agent for its own account. Nothing in this subsection 2.02(d)(ii) shall
be deemed to relieve any Revolving Loan Lender from its obligation to fulfill
its Revolving Credit Commitment hereunder or to prejudice any rights that the
Funding Agent or the Borrower may have against any Revolving Loan Lender as a
result of any default by such Revolving Loan Lender hereunder.

          Section 2.03    Repayment of Loans; Evidence of Debt . (a) (i) The
outstanding principal of all Revolving Loans shall be due and payable on the
Final Maturity Date; provided, however, that, if on February 28, 2004, the Total
Revolving C Credit Commitment is terminated pursuant to Section 2.05(a), (x) the
aggregate outstanding principal of the Revolving C Loans shall be repayable in
monthly installments, on the last day of each month, commencing on February 28,
2004 until paid in full, in an amount equal to $400,000 per month, with the last
such installment to be in the amount necessary to repay in full the unpaid
principal amount of the remaining aggregate outstanding amount of the Revolving
C Loans, and (y) the aggregate outstanding principal of the Foreign Loans shall
be repayable in monthly installments, on the last day of each month, commencing
on February 28, 2004, until paid in full, in an amount equal to $500,000 per
month, with the last such installment to be in the amount necessary to repay in
full the unpaid principal amount of the remaining aggregate outstanding amount
of the Foreign Loans.

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

               (c)  The Funding Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Funding Agent hereunder for the account of the Lenders and each Lender's
share thereof.

               (d)  The entries made in the accounts maintained pursuant to
paragraph (b) or (c) of this Section shall be prima facie evidence of the
existence and amounts of the obligations recorded therein; provided that the
failure of any Lender or the Funding Agent to maintain such accounts or any
error therein shall not in any manner affect the obligation of the Borrower to
repay the Loans in accordance with the terms of this Agreement.

               (e)  Any Lender may request that Loans made by it be evidenced by
a promissory note. In such event, the Borrower shall execute and deliver to such
Lender a promissory note payable to the order of such Lender (or, if requested
by such Lender, to such Lender and its registered assigns) in a form furnished
by the Collateral Agent and reasonably acceptable to the Borrower. Thereafter,
the Loans evidenced by such promissory note and interest thereon shall at all
times (including after assignment pursuant to Section 11.07) be represented by
one or more promissory notes in such form payable to the order of the payee
named therein (or, if such promissory note is a registered note, to such payee
and its registered assigns).

          Section 2.04    Interest. (a) (i)Each Revolving A Loan shall bear
interest on the principal amount thereof from time to time outstanding, from the
date of such Loan until such principal amount becomes due, at a rate per annum

                    (ii)   Each Revolving B Loan shall bear interest on the
principal amount thereof from time to time outstanding, from the date of such
Revolving B Loan until such principal amount becomes due, at a rate per annum
equal to the greater of (i) the Reference Rate plus 4.0 % and (ii) 8.25%;
provided that, so long as no Event of Default has occurred and is continuing, a
portion of the interest on the Revolving B Loans equal to 1.0% per annum that
has accrued during such period (x) shall be capitalized on each interest payment
date and added to the outstanding principal amount of the Revolving B Loans and
the interest otherwise payable in cash shall be reduced by the amount of
interest so capitalized or (y) may, at the option of the Borrower after notice
to the Agents, make such portion of the interest payment in cash. For purposes
of this Agreement and the other Loan Documents, the amounts so capitalized
hereunder shall bear interest in accordance with this Section 2.04 as though
such amounts constituted a Revolving B Loan made by the Revolving B Loan Lenders
to the Borrower.

                    (iii)  Each Revolving C Loan shall bear interest on the
principal amount thereof from time to time outstanding, from the date of such
Revolving C Loan until such principal amount becomes due, at a rate per annum
equal to the greater of (i) the Reference Rate plus 8.0% and (ii) 12.25%;
provided, that, if on February 28, 2004, the then applicable Borrowing Base is
equal to or greater than $110,000,000 and there exists no Event of Default,
interest on each Revolving C Loan shall be at a rate per annum equal to the
greater of (i) the Reference Rate plus 7.0% and (ii) 11.25%; provided, further,
that, so long as no Event of Default has occurred and is continuing, a portion
of the interest on the Revolving C Loans equal to 2.0% per annum that has
accrued during such period (x) shall be capitalized on each interest payment
date and added to the outstanding principal amount of the Revolving C Loans and
the interest otherwise payable in cash shall be reduced by the amount of
interest so capitalized or (y) may, at the option of the Borrower after notice
to the Agents, make such portion of the interest payment in cash. For purposes
of this Agreement and the other Loan Documents, the amounts so capitalized
hereunder shall bear interest in accordance with this Section 2.04 as though
such amounts constituted a Revolving C Loan made by the Revolving C Loan Lenders
to the Borrower.

               (b)  Default Interest. To the extent permitted by law, upon the
occurrence and during the continuance of an Event of Default, the principal of,
and all accrued and unpaid interest on, all Loans, fees, indemnities,
outstanding Reimbursement Obligations or any other Obligations of the Loan
Parties under this Agreement and the other Loan Documents, shall bear interest,
from the date such Event of Default occurred until the date such Event of
Default is cured or waived in writing in accordance herewith, at a rate per
annum equal at all times to the Post-Default Rate.

               (c)  Interest Payment. Interest on each Loan shall be payable
monthly, in arrears, on the first day of each month, commencing on the first day
of the month following the month in which such Loan is made and at maturity
(whether upon demand, by acceleration or otherwise). Interest at the
Post-Default Rate shall be payable on demand. The Borrower hereby authorizes the
Funding Agent to, and the Funding Agent may, from time to time, charge the Loan
Account pursuant to Section 4.02 with the amount of any interest payment due
hereunder.

               (d)  General. All interest shall be computed on the basis of a
year of 360 days for the actual number of days, including the first day but
excluding the last day, elapsed.

          Section 2.05    Reduction of Commitment; Prepayment of Loans .

               (a)  Reduction of Commitments. Each of the Total Revolving A
Credit Commitment, the Total Revolving B Credit Commitment and the Total
Revolving C Credit Commitment shall terminate on the Final Maturity Date;
provided, however, that, if on February 28, 2004, the then applicable Borrowing
Base is less than $110,000,000, the Total Revolving C Credit Commitment shall
terminate. The Borrower may, without premium or penalty, reduce (x) the Total
Revolving A Credit Commitment to an amount (which may be zero) not less than the
sum of (A) the aggregate unpaid principal amount of all Revolving A Loans then
outstanding, (B) the aggregate principal amount of all Revolving A Loans not yet
made as to which a Notice of Borrowing has been given by the Borrower under
Section 2.02, (C) the Letter of Credit Obligations at such time and (D) the
stated amount of all Letters of Credit not yet issued as to which a request has
been made and not withdrawn; (y) the Total Revolving B Credit Commitment to an
amount (which may be zero) not less than the sum of (A) the aggregate unpaid
principal amount of all Revolving B Loans then outstanding, (B) the aggregate
principal amount of all Revolving B Loans not yet made as to which a Notice of
Borrowing has been given by the Borrower under Section 2.02 and (C) the
aggregate principal amount of Revolving B Loans not yet made but which will be
made pursuant to Section 2.05(c)(ii) upon the opening or establishment of a
Letter of Credit pursuant to Section 3.03(a); and (z) the Total Revolving C
Credit Commitment to an amount (which may be zero) not less than the sum of (A)
the aggregate unpaid principal amount of all Revolving C Loans then outstanding,
(B) the aggregate principal amount of all Revolving C Loans not yet made as to
which a Notice of Borrowing has been given by the Borrower under Section 2.02
and (C) the aggregate principal amount of Revolving C Loans not yet made but
which will be made pursuant to Section 2.05(c)(ii) upon the opening or
establishment of a Letter of Credit pursuant to Section 3.03(a). Each such
reduction shall be in an amount which is an integral multiple of $1,000,000
(unless the Total Revolving Credit Commitment in effect immediately prior to
such reduction is less than $1,000,000), shall be made by providing not less
than five (5) Business Days' prior written notice to the Funding Agent and shall
be irrevocable. Once reduced, the Total Revolving A Credit Commitment, the Total
Revolving B Credit Commitment and the Total Revolving C Credit Commitment may
not be increased. Each such reduction of the Total Revolving A Credit
Commitment, the Total Revolving B Credit Commitment or the Total Revolving C
Credit Commitment shall reduce the Revolving A Credit Commitment, the Revolving
B Credit Commitment or the Revolving C Credit Commitment, as the case may be, of
each Lender proportionately in accordance with its Pro Rata Share thereof.

               (b)  Optional Prepayment. The Borrower may prepay without penalty
or premium the principal of any Revolving Loan, in whole or in part.

               (c)  Mandatory Prepayments. (i) If at any time the aggregate
principal amount of all Revolving Loans plus the outstanding amount of all
Letter of Credit Obligations exceeds the Borrowing Base, the Borrower will
immediately prepay the Revolving Loans to the full extent of any such excess. On
each day that any Revolving Loans or Letter of Credit

                                     - 37 -

<PAGE>

Obligations are outstanding, the Borrower shall hereby be deemed to represent
and warrant to the Agents and the Lenders that the Borrowing Base calculated as
of such day equals or exceeds the aggregate principal amount of all Revolving
Loans and Letter of Credit Obligations outstanding on such day. If at any time
after the Borrower has complied with the first sentence of this Section 2.05(c),
the aggregate Letter of Credit Obligations is greater than the lesser of (A) the
then current Borrowing Base and (B) the Total Revolving A Credit Commitment, the
Borrower shall provide cash collateral to the Funding Agent in an amount equal
to 110% of such excess, which cash collateral shall be deposited in an account
under the sole and exclusive control of the Funding Agent for the benefit of the
Agents, the Lenders and/or the L/C Issuer and, provided that no Event of Default
shall have occurred and be continuing, returned to the Borrower, at such time as
the aggregate Letter of Credit Obligations plus the aggregate principal amount
of all outstanding Revolving Loans no longer exceeds the lesser of (A) the then
current Borrowing Base and (B) the Total Revolving A Credit Commitment.

                    (ii)   If at any time the Borrower opens or establishes a
Letter of Credit pursuant to Section 3.03(a) and the maximum amount available
for drawing under such Letter of Credit will exceed the difference between (A)
the Total Revolving A Credit Commitment and (B) the sum of (x) the aggregate
principal amount of the Revolving A Loans and (y) the aggregate Letter of Credit
Obligations, the Borrower will, at the sole discretion of the Funding Agent and
subject to the limitations on the making of Loans set forth in Section 2.01(b),
immediately and automatically, without any action on the part of the Borrower,
be deemed to have requested a Revolving B Loan in any amount equal to such
excess, borrowed such Revolving B Loan from the Revolving B Lenders and used the
proceeds from such Revolving B Loan to repay the Revolving A Loans; provided,
however, that if after giving effect to the making of such Revolving B Loan, the
aggregate principal amount of Revolving B Loans exceeds the Total Revolving B
Credit Commitment, the Borrower will, at the sole discretion of the Funding
Agent and subject to the limitation on the making of Loans set forth in Section
2.01(b), immediately and automatically, without any action on the part of the
Borrower, be deemed to have requested a Revolving C Loan in any amount equal to
such excess, borrowed such Revolving C Loan from the Revolving C Lenders and
used the proceeds from such Revolving C Loan to repay the Revolving A Loans.

                    (iii)  The Funding Agent shall on each Business Day apply
all funds transferred to or deposited in the Funding Agent's Account, to the
payment, in whole or in part, of the outstanding principal amount of the
Revolving Loans.

                    (iv)   Immediately upon any Disposition by any Loan Party or
its Subsidiaries (other than the Foreign Subsidiaries) pursuant to Section
7.02(c)(ii), the Borrower shall prepay the outstanding principal amount of the
Revolving Loans in an amount equal to 100% of the Net Cash Proceeds received by
such Person in connection with such Disposition to the extent that the aggregate
amount of Net Cash Proceeds received by all Loan Parties and such Subsidiaries
(and not paid to the Funding Agent as a prepayment of the Loans) shall exceed
(A) $50,000 for any individual Disposition or (B) $250,000 in the aggregate for
any Fiscal Year for all Dispositions not paid to the Funding Agent as a
prepayment of the Loans. Nothing contained in this subsection (iv) shall permit
any Loan Party or any of its Subsidiaries to make a Disposition of any property
other than in accordance with Section 7.02(c)(ii).

                    (v)    Upon the issuance or incurrence by any Loan Party or
any of its Subsidiaries (other than the Foreign Subsidiaries) of any
Indebtedness (other than Indebtedness referred to in clauses (a), (b), (c), (d),
(e), (f) and (g) of the definition of Permitted Indebtedness), or the sale or
issuance by any Loan Party or any of its Subsidiaries (other than the Foreign
Subsidiaries) of any shares of its Capital Stock (other than in connection with
the exercise of options in accordance with the Borrower's employee stock option
program to the extent that the aggregate Net Cash Proceeds received therefrom in
any Fiscal Year shall not exceed $100,000), the Borrower shall prepay the
outstanding amount of the Revolving Loans in an amount equal to 100% of the Net
Cash Proceeds received by such Person in connection therewith, provided, the
Borrower shall only be required to prepay the outstanding amount of the
Revolving Loans from Net Cash Proceeds received in respect of the exercise of
options in accordance with the Borrower's employee stock option program within
50 days after the end of each fiscal quarter of the Borrower. The provisions of
this subsection (v) shall not be deemed to be implied consent to any such
issuance, incurrence or sale otherwise prohibited by the terms and conditions of
this Agreement.

                    (vi)   Upon the receipt by any Loan Party or any of its
Subsidiaries (other than the Foreign Subsidiaries) of any Extraordinary
Receipts, the Borrowers shall prepay the outstanding principal of the Revolving
Loans in an amount equal to 100% of such Extraordinary Receipts, net of any
reasonable expenses incurred in collecting such Extraordinary Receipts; provided
that, (x) except during the continuance of a Default or an Event of Default, any
insurance or other proceeds not in excess of $100,000 for any one occurrence
received by any Loan Party in connection with the loss, destruction or taking by
condemnation of any Collateral shall not be required to be applied to the
prepayment of the Loans to the extent such net proceeds are used, at the
election of the Borrower, to replace or restore the properties or assets in
respect of which such proceeds were paid if the Borrower delivers a certificate
to the Agents (each, a "Reinvestment Certificate") on or prior to such date
stating that such proceeds shall be used to replace or restore any such
properties or assets within a period specified in such certificate which period
shall not exceed 60 days after the date of receipt of such proceeds and setting
forth estimates of the proceeds to be so expended, (y) such proceeds shall
remain in a Collection Account under the control of the Collateral Agent until
applied in accordance with the preceding clause (x), and (z) if all or any
portion of such proceeds not so applied to the prepayment of the Loans are not
so used within the period specified in the relevant Reinvestment Certificate
furnished pursuant to clause (x) above, such remaining portion shall be applied
to the prepayment of the Loans on the last day of such specified period or there
occurs a Default or Event of Default during such period, such remaining portion
shall be applied immediately to the prepayment of the Loans.

                    (vii)  In the event that the aggregate amount of the Cash
and Cash Equivalents and Permitted Investments of the Loan Parties and their
Subsidiaries (other than the Foreign Subsidiaries) exceeds at any time
$5,000,000, the Borrower shall immediately (but, in any event, within 3 Business
Days) prepay the outstanding principal of the Revolving Loans in the amount
equal to such excess.

                    (viii) Immediately upon the occurrence of any EBITDA
Deficit, the Borrower shall prepay the outstanding principal of the Revolving
Loans in an amount equal to such EBITDA Deficit.

<PAGE>

                    (ix)   Immediately upon receipt of any amount from any
Foreign Subsidiary related to the Foreign Loans, the Borrower shall prepay the
outstanding principal of the Revolving Loans in an amount equal thereto.

               (d)  Application of Payments. In the absence of an Event of
Default, any prepayment pursuant to Section 2.05(c)(i), (c)(iii), (c)(iv),
(c)(v), (c)(vi), (c)(vii), (c)(viii) and (c)(ix) above shall be applied, first,
to the Revolving C Loans, second, to the Revolving B Loans and third, to the
Revolving A Loans.

               (e)  Interest and Fees. Any prepayment made pursuant to this
Section 2.05 (other than prepayments made pursuant to subsections (c)(i) and
(c)(ii) of this Section 2.05) shall be accompanied by accrued interest on the
principal amount being prepaid to the date of prepayment, and if such prepayment
would reduce the amount of the outstanding Loans to zero at a time when the
Total Revolving Credit Commitment has been terminated, such prepayment shall be
accompanied by the payment of all fees accrued to such date pursuant to Section
2.06.

               (f)  Cumulative Prepayments. Except as otherwise expressly
provided in this Section 2.05, payments with respect to any subsection of this
Section 2.05 are in addition to payments made or required to be made under any
other subsection of this Section 2.05.

          Section 2.06    Fees.

               (a)  Unused Line Fee. From and after the Effective Date and until
the Final Maturity Date, the Borrower shall pay to the Funding Agent for the
account of (i) the Revolving A Loan Lenders, in accordance with a written
agreement among the Revolving Loan Lenders, an unused line fee (the "Unused A
Line Fee"), which shall accrue at the rate per annum of 0.5% on the excess, if
any, of the Total Revolving A Credit Commitment over the sum of the average
principal amount of all Revolving A Loans and Letter of Credit Obligations
outstanding from time to time, (ii) the Revolving B Loan Lenders, in accordance
with a written agreement among the Revolving Loan Lenders, an unused line fee
(the "Unused B Line Fee"), which shall accrue at the rate per annum of 0.5% on
the excess, if any, of the Total Revolving B Credit Commitment over the average
principal amount of all Revolving B Loans outstanding from time to time, and
(iii) the Revolving C Loan Lenders, in accordance with a written agreement among
the Revolving Loan Lenders, an unused line fee (the "Unused C Line Fee", and
together with the Unused A Line Fee and the Unused B Line Fee, the "Unused Line
Fee"), which shall accrue at the rate per annum of 0.5% on the excess, if any,
of the Total Revolving C Credit Commitment over the average principal amount of
all Revolving C Loans outstanding from time to time, and in each case, such fees
shall be payable monthly in arrears on the first day of each month commencing
September 1, 2003.

               (b)  Fee Letter Fees. In addition to the fees set forth in this
Agreement, the Borrower agrees to pay to the Agents the fees set forth in the
Fee Letter in the amounts and on the dates set forth in the Fee Letter.

          Section 2.07    Securitization . The Loan Parties hereby acknowledge
that the Lenders and their Affiliates may sell or securitize the Loans (a
"Securitization") through the pledge of the Loans as collateral security for
loans to the Lenders or their Affiliates or through

                                     - 40 -

the sale of the Loans or the issuance of direct or indirect interests in the
Loans, which loans to the Lenders or their Affiliates or direct or indirect
interests will be rated by Moody's, Standard & Poor's or one or more other
rating agencies (the "Rating Agencies"). The Loan Parties shall cooperate with
the Lenders and their Affiliates to effect the Securitization, including,
without limitation, by (a) amending this Agreement and the other Loan Documents,
and executing such additional documents, as reasonably requested by the Lenders
in connection with the Securitization, provided that (i) any such amendment or
additional documentation does not impose material additional costs on the Loan
Parties and (ii) any such amendment or additional documentation does not
materially adversely affect the rights, or materially increase the obligations,
of the Loan Parties under the Loan Documents or change or affect in a manner
adverse to the Loan Parties the financial terms of the Loans, (b) providing such
information as may be reasonably requested by the Lenders in connection with the
rating of the Loans or the Securitization, and (c) providing in connection with
any rating of the Loans a certificate (i) agreeing to indemnify the Lenders and
their Affiliates, any of the Rating Agencies, or any party providing credit
support or otherwise participating in the Securitization (collectively, the
"Securitization Parties") for any losses, claims, damages or liabilities (the
"Liabilities") to which the Lenders, their Affiliates or such Securitization
Parties may become subject insofar as the Liabilities arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any Loan Document or in any writing delivered by or on behalf of
any Loan Party to the Lenders in connection with any Loan Document or arise out
of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, and such indemnity shall survive any transfer by the Lenders or
their successors or assigns of the Loans and (ii) agreeing to reimburse the
Lenders and their Affiliates for any legal or other expenses reasonably incurred
by such Persons in connection with defending the Liabilities.

          Section 2.08   Taxes. (a) All payments made by any Loan Party
hereunder or under any other Loan Document shall be made without set-off,
counterclaim, deduction or other defense. All such payments shall be made free
and clear of and without deduction for any present or future income, franchise,
sales, use, excise, stamp or other taxes, levies, imposts, deductions, charges,
fees, withholdings, restrictions or conditions of any nature now or hereafter
imposed, levied, collected, withheld or assessed by any jurisdiction (whether
pursuant to Federal, state, local or foreign law) or by any political
subdivision or taxing authority thereof or therein, and all interest, penalties
or additional amounts, excluding taxes on the net income and branch profit taxes
of any Lender, any Agent or the L/C Issuer imposed by the jurisdiction in which
such Lender, such Agent or the L/C Issuer is organized or any political
subdivision thereof or taxing authority thereof or any jurisdiction in which
such Person's principal office is located or any political subdivision thereof
or taxing authority thereof (such nonexcluded taxes, levies, imposts,
deductions, charges, fees, withholdings, restrictions, conditions, interest,
penalties and additional amounts being hereinafter collectively referred to as
"Taxes"). If any Loan Party shall be required to deduct or to withhold any Taxes
from or in respect of any amount payable hereunder or under any other Loan
Document,

                    (i)      the amount so payable shall be increased so that
after making all required deductions and withholdings (including Taxes on
amounts payable pursuant to this sentence) the Lenders, the Agents or the L/C
Issuer, as the case may be, receive an

                                     - 41 -

amount equal to the sum they would have received had no such deduction or
withholding been made,

                    (ii)     such Loan Party shall make such deduction or
withholding,

                    (iii)    such Loan Party shall pay the full amount deducted
or withheld to the relevant taxation authority in accordance with applicable
law, and

                    (iv)     as promptly as possible thereafter, such Loan Party
shall send the Lenders, the Agents and the L/C Issuer an official receipt (or,
if an official receipt is not available, such other documentation as shall be
satisfactory to the Lenders, the Agents or the L/C Issuer, as the case may be)
evidencing payment of the amounts so deducted or withheld. In addition, the Loan
Parties agree to pay any present or future taxes, charges or similar levies
which arise from any payment made hereunder or from the execution, delivery,
performance, recordation or filing of, or otherwise with respect to, this
Agreement, the Letters of Credit or any other Loan Document other than the
foregoing excluded taxes (hereinafter referred to as "Other Taxes").

               (b)  The Loan Parties hereby jointly and severally indemnify and
agree to hold the Lenders, the Agents and the L/C Issuer harmless from and
against Taxes or Other Taxes (including, without limitation, any Taxes or Other
Taxes imposed by any jurisdiction on amounts payable under this Section 2.08)
paid by any Lender, any Agent or the L/C Issuer and any liability (including
penalties, interest and expenses for nonpayment, late payment or otherwise)
arising therefrom or with respect thereto, whether or not such Taxes or Other
Taxes were correctly or legally asserted. Such indemnification shall be paid
within 10 days from the date on which any such Lender, any such Agent or the L/C
Issuer makes written demand therefor, which demand shall identify in reasonable
detail the nature and amount of such Taxes or Other Taxes.

               (c)  Each Lender that is organized in a jurisdiction outside the
United States hereby agrees that it shall, no later than the Effective Date or,
in the case of a Lender which becomes a party hereto pursuant to Section 11.07
hereof after the Effective Date, the date upon which such Lender becomes a party
hereto (and from time to time thereafter upon the reasonable request of the
Borrower or any Agent, but only if such Lender is legally able to do so),
deliver to the Borrower and the Agents either (i) two accurate, complete and
signed copies of either (x) U.S. Internal Revenue Service Form W-8ECI or
successor form, or (y) U.S. Internal Revenue Service Form W-8BEN or successor
form, in each case, indicating that such Lender is on the date of delivery
thereof entitled to receive payments of interest hereunder, free from, or
subject to a reduced rate of, or subject to a reduced rate of, withholding of
United States Federal income tax or (ii) in the case of such a Lender that is
entitled to claim exemption from withholding of United States Federal income tax
under Section 871(h) or Section 881(c) of the Internal Revenue Code, (x) a
certificate to the effect that such Lender is (A) not a "bank" within the

881(c)(3)(B) of the Internal Revenue Code and (C) not a controlled foreign
corporation receiving interest from a related person within the meaning of
Section 881(c)(3)(C) of the Internal Revenue Code and (y) two

                                     - 42 -

accurate, complete and signed copies of U.S. Internal Revenue Service Form
W-8BEN or successor form.

               (d)  If any Loan Party fails to perform any of its obligations
under this Section 2.08, the Loan Parties shall indemnify the Lenders, the
Agents and the L/C Issuer for any taxes, interest or penalties that may become
payable as a result of any such failure. The obligations of the Loan Parties
under this Section 2.08 shall survive the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                                   ARTICLE III

                                LETTERS OF CREDIT

          Section 3.01   Letter of Credit Guaranty. (a) In order to assist the
Borrower in establishing or opening standby letters of credit, which shall not
have expiration dates later than the Final Maturity Date (each a "Letter of
Credit"), with the L/C Issuer, the Borrower has requested the Funding Agent to
join in the applications for such Letters of Credit, and/or guarantee payment or
performance of such Letters of Credit and any drafts thereunder through the
issuance of a Letter of Credit Guaranty, thereby lending the Funding Agent's
credit to that of the Borrower, and the Funding Agent has agreed to do so. These
arrangements shall be coordinated by the Funding Agent, subject to the terms and
conditions set forth below. The Funding Agent shall not be required to be the
issuer of any Letter of Credit. The Borrower will be the account party for the
application for each Letter of Credit, which shall be in form and substance
satisfactory to the Funding Agent and the L/C Issuer or on a computer
transmission system approved by the Funding Agent and the L/C Issuer, or such
other written form or computer transmission system as may from time to time be
approved by the Funding Agent and the L/C Issuer, and shall be duly completed in
a manner and at a time reasonably acceptable to the Funding Agent, together with
such other certificates, agreements, documents and other papers and information
as the Funding Agent and the L/C Issuer may reasonably request, which shall
include, without limitation, the requested date of issuance and the name and
address of the beneficiary (the "Letter of Credit Application"). In the event of
any conflict between the terms of any Letter of Credit Application and this
Agreement, for purposes of this Agreement, the terms of this Agreement shall
control.

               (b)  The aggregate Letter of Credit Obligations shall not exceed
the lowest of (i) the difference between (A) the Total Revolving A Credit
Commitment and (B) the aggregate principal amount of all Revolving A Loans then
outstanding, (ii) the difference between (A) the Borrowing Base and (B) the
aggregate principal amount of all Revolving Loans then outstanding, and (iii)
the L/C Subfacility. In addition, the terms and conditions of all Letters of
Credit and all changes or modifications thereof by the Borrower and/or the L/C
Issuer shall in all respects be subject to the prior approval of the Funding
Agent in the reasonable exercise of its sole and absolute discretion; provided,
however, that (i) the expiry date of all Letters of Credit shall be no later
than the Final Maturity Date and (ii) the Letters of Credit and all
documentation in connection therewith shall be in form and substance reasonably
satisfactory to the Funding Agent and the L/C Issuer.

<PAGE>

               (c)  If the Funding Agent is obligated to advance funds under a
Letter of Credit, the Funding Agent may immediately reimburse such disbursement
by charging the Loan Account as set forth below. The Funding Agent shall have
the right, without notice to the Borrower, to charge the Loan Account with the
amount of any and all Indebtedness, liabilities and obligations of any kind
(including indemnification for breakage costs, capital adequacy and reserve
requirement charges) incurred by the Agents or the Revolving A Loan Lenders
under the Letter of Credit Guaranty or incurred by the L/C Issuer with respect
to a Letter of Credit at the earlier of (i) payment by the Funding Agent or the
Revolving A Loan Lenders under the Letter of Credit Guaranty or (ii) the
occurrence of any Default or Event of Default. Any amount charged to the Loan
Account shall be deemed a Revolving A Loan hereunder made by the Revolving A
Loan Lenders to the Borrower, funded by the Funding Agent on behalf of the
Revolving A Loan Lenders and subject to Section 2.02 of this Agreement. Any
charges, fees, commissions, costs and expenses charged to the Funding Agent for
the Borrower's account by the L/C Issuer in connection with or arising out of
Letters of Credit or transactions relating thereto will be charged to the Loan
Account in full when charged to or paid by the Funding Agent and, when charged,
shall be conclusive on the Borrower absent manifest error. Each of the Revolving
A Loan Lenders and the Borrower agrees that the Funding Agent shall have the
right to make such charges regardless of whether any Default or Event of Default
shall have occurred and be continuing or whether any of the conditions precedent
in Section 5.02 have been satisfied.

               (d)  The Borrower understands that the Letter of Credit
Guaranties may require the Revolving A Loan Lenders to indemnify the L/C Issuer
for certain costs or liabilities arising out of claims by the Borrower against
such L/C Issuer. The Borrower agrees to unconditionally indemnify each Agent and
each Lender and hold each Agent and each Revolving A Loan Lender harmless from
any and all loss, claim or liability incurred by any Agent or any Revolving A
Loan Lender arising from any transactions or occurrences relating to Letters of
Credit, any drafts or acceptances thereunder, the Collateral relating thereto,
and all Obligations in respect thereof, including any such loss or claim due to
any action taken by the L/C Issuer, other than for any such loss, claim or
liability arising out of the gross negligence or willful misconduct of the L/C
Issuer, any Agent or any Lender as determined by a final judgment of a court of
competent jurisdiction. The Borrower further agrees to hold each Agent and each
Lender harmless from any error or omission, negligence or misconduct by the L/C
Issuer. The Borrower agrees to be bound by the L/C Issuer's regulations and
interpretations of any Letter of Credit that is the subject of a Letter of
Credit Guaranty and opened to or for the Borrower's account or by the Funding
Agent's interpretations of any Letter of Credit issued for the Borrower's
account, even though such interpretation may be different from the Borrower's
own, and the Borrower understands and agrees that the Lenders, the Agents and
the L/C Issuer shall not be liable for any error, negligence or mistake, whether
of omission or commission, in following the Borrower's instructions or those
contained in the Letter of Credit or any modifications, amendments, or
supplements thereto. The Borrower's unconditional obligations to each Agent,
each Revolving A Lender and the L/C Issuer with respect to Letters of Credit
hereunder shall not be modified or diminished for any reason or in any manner
whatsoever, other than as a result of such Agent's, such Revolving A Loan
Lender's or the L/C Issuer's gross negligence or willful misconduct as
determined by a final judgment of a court of competent jurisdiction. The
Borrower agrees that any charges incurred by the Funding Agent or the L/C Issuer
for the Borrower's account hereunder may be charged to the Loan Account.

<PAGE>

               (e)  Upon any payments made to the L/C Issuer under the Letter of
Credit Guaranty, the Agents or the Revolving A Loan Lenders, as the case may be,
shall, without prejudice to their rights under this Agreement (including that
such unreimbursed amounts shall constitute Loans hereunder), acquire by
subrogation, any rights, remedies, duties or obligations granted or undertaken
by the Borrower in favor of the L/C Issuer in any application for Letters of
Credit, any standing agreement relating to Letters of Credit or otherwise, all
of which shall be deemed to have been granted to the Agents and the Revolving A
Loan Lenders and apply in all respects to the Agents and the Revolving A Loan
Lenders and shall be in addition to any rights, remedies, duties or obligations
contained herein.

          Section 3.02   Participations.

               (a)  Purchase of Participations. Immediately upon issuance by
the L/C Issuer of any Letter of Credit pursuant to this Agreement, each
Revolving A Loan Lender shall be deemed to have irrevocably and unconditionally
purchased and received from the Funding Agent, without recourse or warranty, an
undivided interest and participation, to the extent of such Revolving A Loan
Lender's Pro Rata Share, in all obligations of the Funding Agent in such Letter
of Credit (including, without limitation, all Reimbursement Obligations of the
Borrower with respect thereto pursuant to the Letter of Credit Guaranty or
otherwise).

               (b)  Sharing of Payments. In the event that the Funding Agent
makes any payment in respect of the Letter of Credit Guaranty and the Borrower
shall not have repaid such amount to the Funding Agent, the Funding Agent shall
charge the Loan Account in the amount of the Reimbursement Obligation, in
accordance with Section 3.01(c)and Section 4.02 of this Agreement.

               (c)  Obligations Irrevocable. The obligations of a Revolving A
Loan Lender to make payments to the Funding Agent for the account of the Agents,
the Revolving A Loan Lenders or the L/C Issuer with respect to a Letter of
Credit shall be irrevocable, without any qualification or exception whatsoever
and shall be made in accordance with the terms and conditions of this Agreement
under all circumstances, including, without limitation, any of the following
circumstances:

                    (i)      any lack of validity or enforceability of this
Agreement or any of the other Loan Documents;

                    (ii)     the existence of any claim, setoff, defense or
other right which the Borrower may have at any time against a beneficiary named
in such Letter of Credit or any transferee of such Letter of Credit (or any
Person for whom any such transferee may be acting), any Agent, any Lender, or
any other Person, whether in connection with this Agreement, such Letter of
Credit, the transactions contemplated herein or any unrelated transactions
(including any underlying transactions between the Borrower or any other party
and the beneficiary named in such Letter of Credit);

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

                                     - 45 -

<PAGE>

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

                    (v)      any failure by any Agent to provide any notices
required pursuant to this Agreement relating to such Letter of Credit;

                    (vi)     any payment by the L/C Issuer under such Letter of
Credit against presentation of a draft or certificate which does not comply with
the terms of such Letter of Credit; or

                    (vii)    the occurrence of any Default or Event of Default.

          Section 3.03   Letters of Credit.

               (a)  Request for Issuance. The Borrower may, upon reasonable
notice in advance of such issuance but, in any event, not later than 12:00 noon,
New York City time, at least two (2) Business Days in advance of the issuance
thereof, request the Funding Agent to assist the Borrower in establishing or
opening a Letter of Credit by delivering to the Funding Agent, with a copy to
the L/C Issuer, a Letter of Credit Application, together with any necessary
related documents. The Funding Agent shall not provide support, pursuant to the
Letter of Credit Guaranty, if the Funding Agent shall have received written
notice from the Collateral Agent or the Required Lenders on the Business Day
immediately preceding the proposed issuance date for such Letter of Credit that
one or more of the conditions precedent in Section 5.02 will not have been
satisfied on such date, and the Funding Agent shall not otherwise be required to
determine that, or take notice whether, the conditions precedent set forth in
Section 5.02 have been satisfied.

               (b)  Letter of Credit Fees. (i) The Borrower shall pay to the
Funding Agent for the account of the Revolving A Loan Lenders, in accordance
with a written agreement among the Agents and such Revolving A Loan Lenders' Pro
Rata Shares (determined pursuant to clause (a) of such definition) (x) for any
Letter of Credit issued hereunder, a non-refundable fee equal to 3.25% per annum
of the stated amount of such Letter of Credit, payable monthly in arrears, (y)
for any amendment to an existing Letter of Credit that increases the stated
amount of such Letter of Credit, a non-refundable fee equal to 3.25% per annum
of the increase in the stated amount of such Letter of Credit, payable monthly
in arrears (collectively, the "Letter of Credit Fees").

                    (ii)     L/C Issuer Charges. The Borrower shall pay to the
Funding Agent any and all charges assessed by the L/C Issuer in connection with
the issuance, administration, amendment, payment or cancellation of Letters of
Credit, which charges will constitute standard and customary charges imposed by
the L/C Issuer in connection with all letters of credit administered by the L/C
Issuer.

                    (iii)    Charges to the Loan Account. The Borrower hereby
authorizes the Funding Agent to, and the Funding Agent may, from time to time,
charge the Loan Account pursuant to Section 3.01(c) and Section 4.02 of this
Agreement with the amount of any Letter of Credit fees or charges due under this
Section 3.03.

                                   ARTICLE IV

                      FEES, PAYMENTS AND OTHER COMPENSATION

          Section 4.01   Audit and Collateral Monitoring Fees. The Borrower
acknowledges that pursuant to Section 7.01(f), representatives of the Agents
may, with reasonable advance notice in the absence of an Event of Default, visit
any or all of the Loan Parties and/or conduct audits, inspections, valuations
field examinations and/or title record and land file reviews of any or all of
the Loan Parties at any time and from time to time in a manner so as to not
unduly disrupt the business of the Loan Parties. The Borrower agrees to pay (i)
$1,000 per day per examiner plus the examiner's reasonable out-of-pocket costs
and reasonable expenses incurred in connection with all such visits, audits,
inspections, valuations, field examinations and reviews and (ii) the cost of all
visits, audits, inspections, valuations, field examinations and reviews
conducted by a third party on behalf of the Agents; provided, that, in the
absence of an Event of Default, the Borrower shall pay for no more than (i) four
audits, inspections and field examinations in any twelve month period and (ii)
one valuation for each Fiscal Year, provided, further, that the Borrower shall
pay for all Reserve Reports.

          Section 4.02   Payments; Computations and Statements. (a) The Borrower
will make each payment under this Agreement and the Fee Letter not later than
12:00 noon (New York City time) on the day when due, in lawful money of the
United States of America and in immediately available funds, to the Funding
Agent's Account. All payments received by the Funding Agent after 12:00 noon
(New York City time) on any Business Day will be credited to the Loan Account on
the next succeeding Business Day. All payments shall be made by the Borrower,
without set-off, counterclaim, deduction or other defense, to the Agents and the
Lenders. Except as provided in Section 2.02, after receipt, the Funding Agent
will promptly thereafter cause to be distributed like funds relating to the
payment of principal ratably to the Lenders in accordance with their Pro Rata
Shares and like funds relating to the payment of any other amount payable to any
Lender to such Lender, in each case to be applied in accordance with the terms
of this Agreement, provided that the Funding Agent will cause to be distributed
all interest and fees received from or for the account of the Borrower not less
than once each month and in any event promptly after receipt thereof. The
Lenders and the Borrower hereby authorize the Funding Agent to, and the Funding
Agent may, from time to time, charge the Loan Account of the Borrower with any
amount due and payable by the Borrower under any Loan Document. Each of the
Lenders and the Borrower agrees that the Funding Agent shall have the right to
make such charges whether or not any Default or Event of Default shall have
occurred and be continuing or whether any of the conditions precedent in Section
5.02 have been satisfied. Any amount charged to the Loan Account of the Borrower
shall be deemed a Revolving Loan hereunder made by the Revolving Loan Lenders to
the Borrower, funded by the Funding Agent on behalf of the Revolving Loan
Lenders and subject to Section 2.02 of this Agreement. The Lenders and the
Borrower confirm that any charges which the Funding Agent may so make to the
Loan Account of the Borrower as herein provided will be made as an accommodation
to the Borrower and solely at the Funding Agent's discretion, provided that the
Funding Agent shall from time to time upon the request of the Collateral Agent,
charge the Loan Account of the Borrower with any amount due and payable under
any Loan Document. Whenever any payment to be made under any such Loan Document
shall be stated to be due on a day other than a Business Day, such payment shall
be made on the next succeeding Business Day and such

                                     - 47 -

<PAGE>

extension of time shall in such case be included in the computation of interest
or fees, as the case may be. All computations of fees shall be made by the
Funding Agent on the basis of a year of 360 days for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such fees are payable. Each determination by the Funding Agent of an
interest rate or fees hereunder shall be conclusive and binding for all purposes
in the absence of manifest error.

               (b)  The Funding Agent shall provide the Borrower, promptly after
the end of each calendar month, a summary statement (in the form from time to
time used by the Funding Agent) of the opening and closing daily balances in the
Loan Account of the Borrower during such month, the amounts and dates of all
Loans made to the Borrower during such month, the amounts and dates of all
payments on account of the Loans to the Borrower during such month and the Loans
to which such payments were applied, the amount of interest accrued on the Loans
to the Borrower during such month, any Letters of Credit issued by the L/C
Issuer for the account of the Borrower during such month, specifying the face
amount thereof, the amount of charges to the Loan Account and/or Loans made to
the Borrower during such month to reimburse the Revolving Loan Lenders for
drawings made under Letters of Credit, and the amount and nature of any charges
to the Loan Account made during such month on account of fees, commissions,
expenses and other Obligations. All entries on any such statement shall be
presumed to be correct and, 30 days after the same is sent, shall be final and
conclusive absent manifest error or receipt by the Funding Agent within such 30
day period of a written objection of the Borrower.

          Section 4.03   Sharing of Payments, Etc. Except as provided in
Section 2.02 hereof, if any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) on
account of any Obligation in excess of its ratable share of payments on account
of similar obligations obtained by all the Lenders, such Lender shall forthwith
purchase from the other Lenders such participations in such similar obligations
held by them as shall be necessary to cause such purchasing Lender to share the
excess payment ratably with each of them; provided, however, that if all or any
portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each Lender shall be rescinded and such Lender shall
repay to the purchasing Lender the purchase price to the extent of such recovery
together with an amount equal to such Lender's ratable share (according to the
proportion of (i) the amount of such Lender's required repayment to (ii) the
total amount so recovered from the purchasing Lender of any interest or other
amount paid by the purchasing Lender in respect of the total amount so
recovered). The Borrower agrees that any Lender so purchasing a participation
from another Lender pursuant to this Section 4.03 may, to the fullest extent
permitted by law, exercise all of its rights (including the Lender's right of
set-off) with respect to such participation as fully as if such Lender were the
direct creditor of the Borrower in the amount of such participation.

          Section 4.04   Apportionment of Payments. Subject to Section 2.02
hereof and to any written agreement among the Agents and/or the Lenders:

               (a)  all payments of principal and interest in respect of
outstanding Loans, all payments in respect of the Reimbursement Obligations, all
payments of fees (other than the fees set forth in Section 2.06 hereof to the
extent set forth in a written agreement among

                                     - 48 -

<PAGE>

the Agents and the Lenders, fees with respect to Letters of Credit provided for
in Section 3.03(b)(ii) and the audit and collateral monitoring fee provided for
in Section 4.01) and all other payments (including all proceeds of the
Collateral received by either of the Agents) in respect of any other
Obligations, shall be allocated by the Funding Agent among such of the Lenders
as are entitled thereto, in proportion to their respective Pro Rata Shares or
otherwise as provided herein or, in respect of payments not made on account of
Loans or Letter of Credit Obligations, as designated by the Person making
payment when the payment is made.

               (b)  After the occurrence and during the continuance of an Event
of Default, the Funding Agent may, and upon the direction of the Required
Lenders or the Required Revolving A Lenders shall, apply all payments in respect
of any Obligations and all proceeds of the Collateral, subject to the provisions
of this Agreement: (i) first, ratably to pay the Obligations in respect of any
fees (including any fees or charges assessed by the L/C Issuer), expense
reimbursements, indemnities and other amounts then due to the Agents or the L/C
Issuer until paid in full; (ii) second, ratably to pay the Revolving A Loans in
respect of any fees (including Letter of Credit Fees), expense reimbursements
and indemnities then due to the Revolving A Loan Lenders until paid in full;
(iii) third, ratably to pay interest due in respect of the Agent Advances until
paid in full; (iv) fourth, ratably to pay principal of the Agent Advances until
paid in full; (v) fifth, ratably to pay interest due in respect of the Revolving
A Loans and Reimbursement Obligations until paid in full; (vi) sixth, ratably to
pay principal of the Revolving A Loans and Letter of Credit Obligations (or, to
the extent such Letter of Credit Obligations are contingent, to provide cash
collateral in an amount up to 110% of such Letter of Credit Obligations) then
due and payable until paid in full; (vii) seventh, ratably to pay the Revolving
B Loans and Revolving C Loans in respect of any fees, expense reimbursements and
indemnities then due to the Revolving A Loan Lenders until paid in full; (viii)
eighth, ratably to pay interest due in respect of the Revolving B Loans and the
Revolving C Loans until paid in full; (ix) ninth, ratably to pay principal of
the Revolving B Loans and the Revolving C Loans then due and payable until paid
in full; and (x) tenth, to the ratable payment of all other Obligations then due
and payable.

               (c)  In each instance, so long as no Event of Default has
occurred and is continuing, Section 4.04(b) shall not be deemed to apply to any
payment by the Borrower specified by the Borrower to the Funding Agent to be for
the payment of the principal of or interest on the Revolving B Loans or the
Revolving C Loans or other related Obligations then due and payable under any
provision of this Agreement or the prepayment of all or part of the principal of
the Revolving B Loans or the Revolving C Loans in accordance with the terms and
conditions of Section 2.05.

               (d)  For purposes of Section 4.04(b), "paid in full" means
payment of all amounts owing under the Loan Documents according to the terms
thereof, including loan fees, service fees, professional fees, interest (and
specifically including interest accrued after the commencement of any Insolvency
Proceeding), default interest, interest on interest, and expense reimbursements,
except to the extent that default or overdue interest (but not any other
interest), loan fees, service fees, professional fees, expense reimbursements,
or other fees and expenses, each arising from or related to a default are
disallowed in any Insolvency Proceeding.

               (e)  In the event of a direct conflict between the priority
provisions of this Section 4.04 and other provisions contained in any other Loan
Document, it is the intention of the parties hereto that both such priority
provisions in such documents shall be read together and construed, to the
fullest extent possible, to be in concert with each other. In the event of any
actual, irreconcilable conflict that cannot be resolved as aforesaid, the terms

               (f)  Litigation; Commercial Tort Claims. Except as set forth in
Schedule 6.01(f), (i) there is no pending or, to the best knowledge of any Loan
Party, threatened action, suit or proceeding affecting any Loan Party before any

Agreement or any other Loan Document or any transaction contemplated hereby or

delivered to each Agent and each Lender, fairly present the consolidated
financial condition of the Borrower and its Subsidiaries as at the respective
dates thereof and the consolidated results of operations of the Borrower and its
Subsidiaries for the fiscal periods ended on such respective dates, all in
accordance with GAAP, and since December 31, 2002 no event or development has
occurred that has had or could have a Material Adverse Effect.

                    (ii)   The Borrower has heretofore furnished to each Agent
and each Lender (A) projected monthly estimates of production and statements of
cash flows of the Borrower and its Subsidiaries for the period from July 2003
through December 2004, and (B) projected annual estimates of production and
statements of cash flows of the Borrower and its Subsidiaries for the Fiscal
Years ending in 2003 through 2007, which projected financial statements shall be
updated from time to time pursuant to Section 7.01(a)(ix). Such projections, as
so updated, shall be believed by the Borrower at the time furnished to be
reasonable, shall have been prepared on a reasonable basis and in good faith by
the Borrower, and shall have been based on assumptions believed by the Borrower
to be reasonable at the time made and upon the best information then reasonably
available to the Borrower, and the Borrower shall not be aware of any facts or
information that would lead it to believe that such projections, as so updated,
are incorrect or misleading in any material respect.

               (h)  Compliance with Law, Etc. No Loan Party is in violation of
its organizational documents, any material law, rule, regulation, judgment or
order of any Governmental Authority applicable to it or any of its property or
assets, or any material term of any agreement or instrument (including, without
limitation, any Material Contract) binding on or otherwise affecting it or any
of its properties, and no Default or Event of Default has occurred and is
continuing. The Loan Parties have not violated any material laws or failed to

<PAGE>

and/or operations of any their Oil and Gas Properties or the conduct of their
business. The Oil and Gas Properties of the Loan Parties (and properties
utilized therewith) have been maintained, operated and developed in a good and
workmanlike manner and in substantial conformity with all applicable laws and
all rules, regulations and orders of all duly constituted authorities
(including, without limitation, the MMS) having jurisdiction and in substantial
conformity with the provisions of all leases, subleases or other contracts
comprising a part of the Hydrocarbon Interests and other contracts and
agreements forming a part of the Oil and Gas Properties of the Loan Parties;
specifically in this connection, (i) no Oil and Gas Property of the Loan Parties
is subject to having allowable production reduced below the full and regular
allowable production (including the maximum permissible tolerance) because of
any overproduction (whether or not the same was permissible at the time) and
(ii) none of the wells comprising a part of the Oil and Gas Properties of the
Loan Parties (or properties utilized therewith) deviate from the vertical more
than the maximum permitted by applicable laws, regulations, rules and orders,
and such wells are, in fact, bottomed under and are producing from, and the well
bores are wholly within, the Oil and Gas Properties of the Loan Parties (or in
the case of wells located on real property utilized therewith, such utilized
real property) covered by the applicable leases that are the subject to the
title opinions delivered pursuant to Section 5.01(d)(i)(v).

which have been filed with the Internal Revenue Service and delivered to the
Agents, is complete and correct and fairly presents the funding status of such
Employee Plan, and since the date of such report there has been no material
adverse change in such funding status, (iv) copies of each agreement entered
into with the PBGC, the U.S. Department of Labor or the Internal Revenue Service
with respect to any Employee Plan have been delivered to the Agents, (v) no
Employee Plan had an accumulated or waived funding deficiency or permitted
decrease which would create a deficiency in its funding standard account or has
applied for an extension of any amortization period within the meaning of
Section 412 of the Internal Revenue Code at any time during the previous 60
months, and (vi) no Lien imposed under the Internal Revenue Code or ERISA exists
or is likely to arise on account of any Employee Plan within the meaning of
Section 412 of the Internal Revenue Code. No Loan Party or any of its ERISA
Affiliates has incurred any withdrawal liability under ERISA with respect to any
Multiemployer Plan, or is aware of any facts indicating that it or any of its
ERISA Affiliates may in the future incur any such withdrawal liability. No Loan
Party or any of its ERISA Affiliates nor any fiduciary of any Employee Plan has
(i) engaged in a nonexempt prohibited transaction described in Section 406 of
ERISA or Section 4975 of the Internal Revenue Code, (ii) failed to pay any
required installment or other payment required under Section 412 of the Internal
Revenue Code on or before the due date for such required installment or payment,
(iii) engaged in a transaction within the meaning of Section 4069 of ERISA or

Party, threatened claims, actions, proceedings or lawsuits (other than claims
for benefits in the normal course) asserted or instituted against (i) any
Employee Plan or its assets, (ii) any fiduciary with respect to any Employee
Plan, or (iii) any Loan Party or any of its ERISA Affiliates with respect to any
Employee Plan. Except as required

                                     - 60 -

<PAGE>

by Section 4980B of the Internal Revenue Code, no Loan Party or any of its ERISA
Affiliates maintains an employee welfare benefit plan (as defined in Section
3(1) of ERISA) which provides health or welfare benefits (through the purchase
of insurance or otherwise) for any retired or former employee of any Loan Party
or any of its ERISA Affiliates or coverage after a participant's termination of
employment.

               (j)  Taxes, Etc. All Federal, state and local tax returns and
other reports required by applicable law to be filed by any Loan Party have been
filed, or extensions have been obtained, and all taxes, assessments and other
governmental charges imposed upon any Loan Party or any property of any Loan
Party and which have become due and payable on or prior to the date hereof have
been paid, except to the extent contested in good faith by proper proceedings
which stay the imposition of any penalty, fine or Lien resulting from the
non-payment thereof and with respect to which adequate reserves have been set
aside for the payment thereof on the Financial Statements in accordance with
GAAP.

               (k)  Regulations T, U and X. No Loan Party is or will be engaged
in the business of extending credit for the purpose of purchasing or carrying
margin stock (within the meaning of Regulation T, U or X), and no proceeds of

to others for the purpose of purchasing or carrying any margin stock.

               (l)  Nature of Business. No Loan Party is engaged in any business
other than the Oil and Gas Business.

               (m)  Adverse Agreements, Etc. No Loan Party is a party to any
agreement or instrument, or subject to any charter, limited liability company
agreement, partnership agreement or other corporate, partnership or limited
liability company restriction or any judgment, order, regulation, ruling or
other requirement of a court or other Governmental Authority, which has, or in
the future could have, a Material Adverse Effect.

               (n)  Permits, Etc. Each Loan Party has, and is in compliance
with, all material permits, licenses, authorizations, approvals, entitlements
and accreditations required for such Person lawfully to own, lease, manage or
operate, or to acquire, each business currently owned, leased, managed or
operated, or to be acquired, by such Person. No condition exists or event has
occurred which, in itself or with the giving of notice or lapse of time or both,
would result in the suspension, revocation, impairment, forfeiture or
non-renewal of any such permit, license, authorization, approval, entitlement or
accreditation, and there is no claim that any thereof is not in full force and
effect. No Loan Party has received any notices concerning, and there are no
existing orders of, proceedings pending before, or other requirements of, any
Governmental Authority, including, without limitation, the Bureau of Land
Management, the MMS or the Federal Energy Regulatory Commission and any
comparable state or local Governmental Authority, which could or will materially
interfere with, limit or otherwise restrict the Oil and Gas Business of the Loan
Parties or which could or will require any such Loan Party to refund or
otherwise return any portion of the proceeds received or to be received from the
sale of Hydrocarbons by any such Loan Party.

               (o)  Properties. (i) Except with respect to its Oil and Gas
Properties, each Loan Party has good and marketable title to, valid leasehold
interests in, or valid licenses to use, all property and assets material to its
business, free and clear of all Liens, except Permitted Liens. All such
properties and assets are in good working order and condition, ordinary wear and
tear excepted.

                    (ii)   Part A of Schedule 6.01(o) sets forth a complete and
accurate list, as of the Effective Date, of the location, by state and street
address, of all real property owned or leased by each Loan Party other than its
Oil and Gas Properties. Part B of Schedule 6.01(o) lists completely and
correctly, as of the Effective Date, all Oil and Gas Properties whether leased
or owned by any Loan Party, including, without limitation, the respective
counties or parishes and states in which such Oil and Gas Properties are located
and OCS lease number or other similar state lease number, if applicable. As of
the Effective Date, each Loan Party has valid leasehold interests in the Leases
described on Schedule 6.01(o) to which it is a party. Schedule 6.01(o) sets
forth with respect to each such Lease set forth in Part A thereof, the
commencement date, termination date, renewal options (if any) and annual base
rents. Each such Lease is valid and enforceable in accordance with its terms in
all material respects and is in full force and effect. No consent or approval of
any landlord or other third party in connection with any such Lease is necessary
for any Loan Party to enter into and execute the Loan Documents to which it is a
party, except as set forth on Schedule 6.01(o). To the best knowledge of any
Loan Party, no other party to any such Lease is in default of its obligations
thereunder, and no Loan Party (or any other party to any such Lease) has at any
time delivered or received any notice of default which remains uncured under any
such Lease and, as of the Effective Date, no event has occurred which, with the
giving of notice or the passage of time or both, would constitute a default
under any such Lease.

                    (iii)  The Borrower has good and defensible title to all of
its Oil and Gas Properties set forth in Part B of Schedule 6.01(o) which
constitute real property and good and defensible title to all of its Oil and Gas
Properties which constitute personal property, except for (A) such imperfections
of title which do not in the aggregate materially detract from the value thereof
to, or the use thereof in, the business of the Borrower or any of its
Subsidiaries and (B) Permitted Liens. The quantum and nature of the interest of
the Borrower in and to the Oil and Gas Properties as set forth in the most
recent Reserve Report includes the entire interest of the Borrower in such Oil
and Gas Properties as of the date of such Reserve Report, and are complete and
accurate in all material respects as of the date of such Reserve Report; there
are no "back-in" or "reversionary" interests held by third parties which could
materially reduce the interest of the Borrower in such Oil and Gas Properties
except as expressly set forth in such Reserve Report, and the ownership of the
Oil and Gas Properties by the Borrower shall not in any material respect
obligate any such Loan Party to bear the costs and expenses relating to the
maintenance, development or operations of each such Oil and Gas Property in an
amount in excess of the working interest of such Loan Party in each Oil and Gas
Property set forth in, such Reserve Report.

                    (iv)   The Borrower's marketing, gathering, transportation,
processing and treating facilities and equipment, together with any marketing,
gathering, transportation, processing and treating contracts in effect among the
Borrower and any other

Person, are sufficient to gather transport, process and/or treat, reasonably
anticipated volumes of production of Hydrocarbons from the Oil and Gas
Properties of the Borrower.

               (p)  Full Disclosure. Each Loan Party has disclosed to the Agents
all agreements, instruments and corporate or other restrictions to which it is
subject, and all other matters known to it, that, individually or in the
aggregate, could result in a Material Adverse Effect. None of the other reports,
financial statements, certificates or other information furnished by or on
behalf of any Loan Party to the Agents in connection with the negotiation of
this Agreement or delivered hereunder (as modified or supplemented by other
information so furnished) contains any material misstatement of fact or omits to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which it was made, not misleading; provided that,
with respect to projected financial information, each Loan Party represents only
that such information was prepared in good faith based upon assumptions believed
to be reasonable at the time. There is no contingent liability or fact that may
have a Material Adverse Effect which has not been set forth in a footnote
included in the Financial Statements or a Schedule hereto.

               (q)  Operating Lease Obligations. On the Effective Date, none of
the Loan Parties has any Operating Lease Obligations other than the Operating
Lease Obligations set forth on Schedule 6.01(q).

6.01(r), (i) the operations of each Loan Party are in material compliance with
all Environmental Laws; (ii) there has been no Release at any of the properties

Party or any predecessor in interest nor does any Loan Party have knowledge or
notice of any threatened or pending Environmental Action against any Loan Party

received Hazardous Materials generated by any Loan Party or any predecessor in
interest which could have a Material Adverse Effect; (v) no property now or
formerly owned or operated by a Loan Party has been used as a treatment or
disposal site for any Hazardous Material; (vi) no Loan Party has failed to
report to the proper Governmental Authority any Release which is required to be
so reported by any Environmental Laws which could have a Material Adverse
Effect; (vii) each Loan Party holds all licenses, permits and approvals required
under any Environmental Laws in connection with the operation of the business
carried on by it, except for such licenses, permits and approvals as to which a
Loan Party's failure to maintain or comply with could not have a Material
Adverse Effect; (viii) no Loan Party has received any notification pursuant to
any Environmental Laws that (A) any work, repairs, construction or Capital
Expenditures are required to be made in respect as a condition of continued
compliance with any Environmental Laws, or any license, permit or approval
issued pursuant thereto or (B) any license, permit or approval referred to above
is about to be reviewed, made, subject to limitations or conditions, revoked,
withdrawn or terminated, in each case, except as could not have a Material
Adverse Effect; and (ix) the Loan Parties have posted bonds or other financial
assurances sufficient to comply with all Environmental Laws, each of which is
set forth in Schedule 6.01(r).

               (s)  Insurance and Bonds. Each Loan Party keeps its property
adequately insured and maintains (i) insurance to such extent and against such
risks, including fire, as is customary with companies in the same or similar
businesses, (ii) workmen's compensation insurance in the amount required by

required by law or as may be reasonably required by the Collateral Agent
(including, without limitation, against larceny, embezzlement or other criminal
misappropriation). Schedule 6.01(s) sets forth a list of all insurance
maintained by each Loan Party on the Effective Date. Schedule 6.01(s) contains
an accurate and complete description of all performance bonds related to
operations on or pertaining to the Oil and Gas Properties owned or held by the
Borrower and each of its Subsidiaries (other than the Foreign Subsidiaries).
Except as set forth on Schedule 6.01(s), such bonds are sufficient for
compliance with all requirements of law and of all agreements to which the
Borrower or any of its Subsidiaries (other than the Foreign Subsidiaries) is a
party; are valid, outstanding and enforceable policies; provide adequate
coverage in at least such amounts and against at least such risks (but including
in any event public liability) as are required by Governmental Authorities
and/or usually insured or bonded against in the same general area by companies
engaged in the same or a similar business for the assets and operations of the
Borrower and each of its Subsidiaries (other than the Foreign Subsidiaries);
will remain in full force and effect through the respective dates set forth in
Schedule 6.01(s) without the payment of additional premiums except as set forth
on Schedule 6.01(s); and will not in any way be affected by, or terminate or
lapse by reason of, the transactions contemplated by this agreement. Neither the
Borrower nor any of its Subsidiaries (other than the Foreign Subsidiaries) has
been refused any bonds or insurance with respect to its assets or operations,
nor has its coverage been limited below usual and customary bond or policy
limits, by any bonding company or insurance carrier to which it has applied for
any such bond or insurance or with which it has carried insurance during the
last three years.

               (t)  Use of Proceeds. The proceeds of the Loans shall be used (a)

fees and expenses in connection with the transactions contemplated hereby, (d)
to fund working capital of the Borrower, and (e) subject to the terms and

shall be pursuant to a budget to be delivered by the Borrower to the Agents, the
form and substance of which shall be satisfactory to the Agents in their sole
discretion (the "Foreign Working Capital Budget"). The Letters of Credit will be
used for general working capital purposes.

               (u)  Solvency. After giving effect to the transactions

franchises, authorizations, non-governmental licenses and permits and other
intellectual property rights that are necessary for the operation of its
business, without infringement upon or conflict with the rights of any other
Person with respect thereto, except for such infringements and conflicts which,

Date of all such material licenses, permits, patents, patent applications,

or other advertising device, product, process, method, substance, part or other
material now employed, or now contemplated to be employed, by any Loan Party
infringes upon or conflicts with any rights owned by any other Person, and no
claim or litigation regarding any of the foregoing is pending or threatened,
except for such infringements and conflicts which could not have, individually
or in the aggregate, a Material Adverse Effect. To the best knowledge of each
Loan Party, no patent, invention, device, application, principle or any statute,

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), as of
the Effective Date, there exist no Material Contracts which are not cancelable
on 60 days' notice or less without penalty or detriment for the sale of

and Retraining Notification Act ("WARN") or similar state law, which remains
unpaid or unsatisfied. The hours worked and payments made to employees of any
Loan Party have not been in violation of the Fair Labor Standards Act or any
other applicable legal requirements. All material payments due from any Loan
Party on account of wages and employee health and welfare insurance and other
benefits have been paid or accrued as a liability on the books of such Loan
Party.

               (aa) Customers and Suppliers. There exists no actual or

7.01(a)(vi), on a net basis there are not gas imbalances, take-or-pay oil and

its Subsidiaries fails to maintain such insurance, the Collateral Agent may
arrange for such insurance, but at the Borrower's expense and without any
responsibility on the Collateral Agent's part for obtaining the insurance, the
solvency of the insurance companies, the adequacy of the coverage, or the
collection of claims. Upon the occurrence and during the continuance of an Event

Lenders, any Loan Party and its Subsidiaries, to file claims under any insurance
policies, to receive, receipt and give acquittance for any payments that may be
payable thereunder, and to execute any and all endorsements, receipts, releases,
assignments, reassignments or other documents that may be necessary to effect

covering all persons employed by the Borrower or its agents or subcontractors of
any tier in connection with any construction affecting such Oil and Gas
Properties, including, without limitation, all agents and employees of the
Borrower and the Borrower's subcontractors with respect to whom death or bodily
injury claims could be asserted against the Borrower.

                      MANAGEMENT, COLLECTION AND STATUS OF
                    ACCOUNTS RECEIVABLE AND OTHER COLLATERAL

          Section 8.01   Collection of Accounts Receivable; Management of
Collateral. (a) On or prior to the Effective Date, the Loan Parties shall assist
the Funding Agent in establishing, and, during the term of this Agreement,
maintaining, one or more blocked accounts in the name of the Funding Agent (for
the benefit of the Borrower) and identified on Schedule 8.01 hereto
(collectively, the "Collection Accounts") with the financial institutions set
forth on Schedule 8.01 hereto or such other financial institutions selected by
the Loan Parties and acceptable to the Funding Agent in its sole discretion
(each being referred to as a "Collection Account Bank"). If any Account Debtor
of the Loan Parties remits payments by wire transfer or by Automated Clearing
House, Inc. and does not remit such payments into a Collection Account, the Loan
Parties shall irrevocably instruct such Account Debtor, with respect to Accounts
Receivable of the Loan Parties, to remit all payments made by wire transfer or
by Automated Clearing House, Inc. payment to a Collection Account or into
another account as may be directed by the Funding Agent. All Collections
received directly by the Loan Parties from any of their Account Debtors shall be
held by the Loan Parties in trust for the Agents and the Lenders and, upon
receipt by the Borrower, be deposited by the Loan Parties in original form, no
later than the next Business Day after receipt thereof, into a Collection
Account. Each Collection Account Bank shall deposit and/or credit all amounts
received by it into the Collection Account at such Collection Account Bank on
the day received or, if such day is not a Business Day, on the next succeeding
Business Day. The Loan Parties shall not commingle any Collections with the Loan
Parties' own funds or the funds of any of their Subsidiaries or Affiliates or
with the proceeds of any assets not included in the Collateral. Until the
Funding Agent shall advise the Loan Parties to the contrary after the occurrence
and during the continuance of a Specified Event of Default, the Loan Parties may
and will enforce, collect and receive all amounts owing on the Accounts
Receivable of the Loan Parties for and on the Funding Agent's benefit and
behalf, but at the Loan Parties' expense, and such privilege shall terminate, at
the election of any Agent, upon the occurrence and during the continuance of a
Specified Event of Default. Subject to Section 2.05 and prior to the occurrence
of a Specified Event of Default, the Loan Parties may use the proceeds of
Collateral in the ordinary course of business. After the occurrence and during
the continuance of a Specified Event of Default or pursuant to the provisions of
Section 2.05(c)(vi) with respect to proceeds subject to a Reinvestment
Certificate, at the election of any Agent, upon its sole and absolute
discretion, or at the request of the Required Lenders, all funds received in the
Collection Account shall be sent by wire transfer or Automated Clearing House,
Inc. payment to the Funding Agent's Account for application at the end of each
Business Day to reduce the then principal balance of the Revolving Loans,
conditional upon final payment to the Funding Agent. No checks, drafts or other
instruments received by the Funding Agent shall

                                     - 92 -

<PAGE>

constitute final payment to the Funding Agent unless and until such checks,
drafts or instruments have actually been collected.

               (b)  After the occurrence and during the continuance of an Event
of Default, the Collateral Agent may send a notice of assignment and/or notice
of the Lenders' security interest to any and all Account Debtors or third
parties holding or otherwise concerned with any of the Collateral, and
thereafter the Collateral Agent shall have the sole right to collect the
Accounts Receivable and/or take possession of the Collateral and the books and
records relating thereto. The Loan Parties shall not, without prior written
consent of the Collateral Agent, grant any extension of time of payment of any
Account Receivable, compromise or settle any Account Receivable for less than
the full amount thereof, release, in whole or in part, any Person or property
liable for the payment thereof, or allow any credit or discount whatsoever
thereon, except, in the absence of a continuing Event of Default, as permitted
by Section 7.02(o).

               (c)  Each Loan Party hereby appoints each Agent or its designee
on behalf of such Agent as the Loan Parties' attorney-in-fact with power
exercisable during the continuance of an Event of Default to endorse any Loan
Party's name upon any notes, acceptances, checks, drafts, money orders or other
evidences of payment relating to the Accounts Receivable, to sign any Loan
Party's name on any invoice or bill of lading relating to any of the Accounts
Receivable, drafts against Account Debtors with respect to Accounts Receivable,
assignments and verifications of Accounts Receivable and notices to Account
Debtors with respect to Accounts Receivable, to send verification of Accounts
Receivable, and to notify the Postal Service authorities to change the address
for delivery of mail addressed to any Loan Party to such address as such Agent
may designate and to do all other acts and things necessary to carry out this
Agreement. All acts of said attorney or designee are hereby ratified and
approved, and said attorney or designee shall not be liable for any acts of
omission or commission (other than acts of omission or commission constituting
gross negligence or willful misconduct as determined by a final judgment of a
court of competent jurisdiction), or for any error of judgment or mistake of
fact or law; this power being coupled with an interest is irrevocable until all
of the Loans, Reimbursement Obligations, Letter of Credit Obligations and other
Obligations under the Loan Documents are paid in full and all of the Loan
Documents are terminated.

               (d)  Nothing herein contained shall be construed to constitute
any Agent as agent of any Loan Party for any purpose whatsoever, and the Agents
shall not be responsible or liable for any shortage, discrepancy, damage, loss
or destruction of any part of the Collateral wherever the same may be located
and regardless of the cause thereof (other than from acts of omission or
commission constituting gross negligence or willful misconduct as determined by
a final judgment of a court of competent jurisdiction). The Agents shall not,
under any circumstance or in any event whatsoever, have any liability for any
error or omission or delay of any kind occurring in the settlement, collection
or payment of any of the Accounts Receivable or any instrument received in
payment thereof or for any damage resulting therefrom (other than acts of
omission or commission constituting gross negligence or willful misconduct as
determined by a final judgment of a court of competent jurisdiction). The
Agents, by anything herein or in any assignment or otherwise, do not assume any
of the obligations under any contract or agreement assigned to any Agent and
shall not be responsible in any way for the performance by any Loan Party of any
of the terms and conditions thereof.

<PAGE>

               (e)  If any Account Receivable includes a charge for any tax
payable to any Governmental Authority, each Agent is hereby authorized (but in
no event obligated) in its discretion to pay the amount thereof to the proper
taxing authority for the Loan Parties' account and to charge the Loan Parties
therefor. The Loan Parties shall notify the Agents if any Account Receivable
includes any taxes due to any such Governmental Authority and, in the absence of
such notice, the Agents shall have the right to retain the full proceeds of such
Account Receivable and shall not be liable for any taxes that may be due by
reason of the sale and delivery creating such Account Receivable.

               (f)  Notwithstanding any other terms set forth in the Loan
Documents, the rights and remedies of the Agents and the Lenders herein
provided, and the obligations of the Loan Parties set forth herein, are
cumulative of, may be exercised singly or concurrently with, and are not
exclusive of, any other rights, remedies or obligations set forth in any other
Loan Document or as provided by law.

          Section 8.02   Accounts Receivable Documentation. The Loan Parties
will at such intervals as the Agents may require, execute and deliver
confirmatory written assignments of the Accounts Receivable to the Agents and
furnish such further schedules and/or information as any such Agent may require
relating to the Accounts Receivable, including, without limitation, sales
invoices or the equivalent, credit memos issued, remittance advices, reports and
copies of deposit slips and copies of original shipping or delivery receipts for
all merchandise sold. In addition, the Loan Parties shall notify the Agents of
any non-compliance in respect of the representations, warranties and covenants
contained in Section 8.03. The items to be provided under this Section 8.02 are
to be in form reasonably satisfactory to the Agents and are to be executed and
delivered to the Agents from time to time solely for their convenience in
maintaining records of the Collateral. The Loan Parties' failure to give any of
such items to the Agents shall not affect, terminate, modify or otherwise limit
the Collateral Agent's Lien on the Collateral. The Loan Parties shall not
re-date any invoice or sale or make sales on extended dating beyond that
customary in the Loan Parties' industry, and shall not re-bill any Accounts
Receivable without promptly disclosing the same to the Agents and providing the
Agents with a copy of such re-billing, identifying the same as such. If the Loan
Parties become aware of anything materially detrimental to any of the Loan
Parties' customers' credit, the Loan Parties will promptly advise the Agents
thereof.

          Section 8.03   Status of Accounts Receivable and Other Collateral.
With respect to Collateral of any Loan Party at the time the Collateral becomes
subject to the Collateral Agent's Lien, each Loan Party covenants, represents
and warrants: (a) such Loan Party shall be the sole owner, free and clear of all
Liens (except for the Liens granted in the favor of the Collateral Agent for the
benefit of the Lenders and other Permitted Liens), and shall be fully authorized
to sell, transfer, pledge and/or grant a security interest in each and every
item of said Collateral; (b) each Account Receivable shall be a good and valid
account representing an undisputed bona fide indebtedness incurred or an amount
indisputably owed by the Account Debtor therein named, for a fixed sum as set
forth in the invoice relating thereto with respect to an absolute sale and
delivery upon the specified terms of goods sold or services rendered by such
Loan Party; (c) no Account Receivable shall be subject to any defense, offset,
counterclaim, discount or allowance except as may be stated in the invoice
relating thereto, discounts and allowances as may be customary in such Loan
Party's business and as otherwise disclosed to the

                                     - 94 -

<PAGE>

Agents, and each Account Receivable will be paid when due; (d) none of the
transactions underlying or giving rise to any Account Receivable shall violate
any applicable state or federal laws or regulations, and all documents relating
thereto shall be legally sufficient under such laws or regulations and shall be
legally enforceable in accordance with their terms; (e) no agreement under which
any deduction or offset of any kind, other than normal trade discounts, may be
granted or shall have been made by such Loan Party at or before the time such
Account Receivable is created; (f) all agreements, instruments and other
documents relating to any Account Receivable shall be true and correct and in
all material respects what they purport to be; (g) all signatures and
endorsements that appear on all material agreements, instruments and other
documents relating to any Account Receivable shall be genuine and all
signatories and endorsers shall have full capacity to contract; (h) such Loan
Party shall maintain books and records pertaining to said Collateral in such
detail, form and scope as the Agents shall reasonably require; (i) such Loan
Party shall immediately notify the Agents if any Account Receivable arises out
of contracts with any Governmental Authority, and will execute any instruments
and take any steps required by the Agents in order that all monies due or to
become due under any such contract shall be assigned to the Collateral Agent and
notice thereof given to such Governmental Authority under the Federal Assignment
of Claims Act or any similar state or local law; (j) such Loan Party will,
immediately upon learning thereof, report to the Agents any material loss or
destruction of, or substantial damage to, any of the Collateral, and any other
matters affecting the value, enforceability or collectibility of any of the
Collateral; (k) if any amount payable under or in connection with any Account
Receivable is evidenced by a promissory note or other instrument, such
promissory note or instrument shall be immediately pledged, endorsed, assigned
and delivered to the Collateral Agent for the benefit of the Lenders as
additional Collateral; (l) such Loan Party shall not re-date any invoice or sale
or make sales on extended dating beyond that which is customary in the ordinary
course of its business and in the industry; (m) such Loan Party shall conduct a
physical count of its Inventory at such intervals as any Agent may request and
such Loan Party shall promptly supply the Agents with a copy of such count
accompanied by a report of the value (based on the lower of cost (on a first in
first out basis) and market value) of such Inventory; and (n) such Loan Party is
not and shall not be entitled to pledge any Agent's or any Lender's credit on
any purchases or for any purpose whatsoever.

          Section 8.04   Collateral Custodian. Upon the occurrence and during
the continuance of any Default or Event of Default, the Collateral Agent may at
any time and from time to time employ and maintain on the premises of any Loan
Party a custodian selected by the Collateral Agent who shall have full authority
to do all acts necessary to protect the Agents' and the Lenders' interests. Each
Loan Party hereby agrees to, and to cause its Subsidiaries to, cooperate with
any such custodian and to do whatever the Collateral Agent may reasonably
request to preserve the Collateral. All costs and expenses incurred by the
Collateral Agent by reason of the employment of the custodian shall be the
responsibility of the Borrower and charged to the Loan Account.

otherwise related to any of same to the extent reasonably incidental to the
exercise by such Agent of the rights and remedies specifically authorized to be
exercised by such Agent by the terms of this Agreement or any other Loan
Document; (vii) to incur and pay such fees necessary or appropriate for the
performance and fulfillment of its functions and powers pursuant to this
Agreement or any other Loan Document; and (viii) subject to Section 10.03 of
this Agreement, to take such action as such Agent deems appropriate on its
behalf to administer the Loans and the Loan Documents and to exercise such other
powers delegated to such Agent by the terms hereof or the other Loan Documents
(including, without limitation, the power to give or to refuse to give notices,
waivers, consents, approvals and instructions and the power to make or to refuse
to make determinations and calculations) together with such powers as are
reasonably incidental thereto to carry out the purposes hereof and thereof. As
to any matters not expressly provided for by this Agreement and the other Loan
Documents (including, without limitation, enforcement or collection of the
Loans), the Agents shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Required Lenders, and such instructions of the Required Lenders shall be
binding upon all Lenders and all makers of Loans; provided, however, that the
L/C Issuer shall not be required to refuse to honor a drawing under any Letter
of Credit and the Agents shall not be required to take any action which, in the
reasonable opinion of any Agent, exposes such Agent to liability or which is
contrary to this Agreement or any other Loan Document or applicable law.

          Section 10.02  Nature of Duties. The Agents shall have no duties or
responsibilities except those expressly set forth in this Agreement or in the
other Loan Documents. The duties of the Agents shall be mechanical and
administrative in nature. The Agents shall not have by reason of this Agreement
or any other Loan Document a fiduciary relationship in respect of any Lender.
Nothing in this Agreement or any other Loan Document, express or implied, is
intended to or shall be construed to impose upon the Agents any obligations in
respect of this Agreement or any other Loan Document except as expressly set
forth herein or therein. Each Lender shall make its own independent
investigation of the financial condition and affairs of the Loan Parties in
connection with the making and the continuance of the Loans hereunder and shall
make its own appraisal of the creditworthiness of the Loan Parties and the value
of the Collateral, and the Agents shall have no duty or responsibility, either
initially or on a continuing basis, to provide any Lender with any credit or
other information with respect thereto, whether coming into their possession
before the initial Loan hereunder or at any time or times thereafter, provided
that, upon the reasonable request of a

                                     - 100 -

<PAGE>

Lender, each Agent shall provide to such Lender any documents or reports
delivered to such Agent by the Loan Parties pursuant to the terms of this
Agreement or any other Loan Document. If any Agent seeks the consent or approval
of the Required Lenders to the taking or refraining from taking any action
hereunder, such Agent shall send notice thereof to each Lender. Each Agent shall
promptly notify each Lender any time that the Required Lenders have instructed
such Agent to act or refrain from acting pursuant hereto.

          Section 10.03  Rights, Exculpation, Etc. The Agents and their
directors, officers, agents or employees shall not be liable for any action
taken or omitted to be taken by them under or in connection with this Agreement
or the other Loan Documents, except for their own gross negligence or willful
misconduct as determined by a final judgment of a court of competent
jurisdiction. Without limiting the generality of the foregoing, the Agents (i)
may treat the payee of any Loan as the owner thereof until the Collateral Agent
receives written notice of the assignment or transfer thereof, pursuant to
Section 11.07 hereof, signed by such payee and in form satisfactory to the
Collateral Agent; (ii) may consult with legal counsel (including, without
limitation, counsel to any Agent or counsel to the Loan Parties), independent
public accountants, and other experts selected by any of them and shall not be
liable for any action taken or omitted to be taken in good faith by any of them
in accordance with the advice of such counsel or experts; (iii) make no warranty
or representation to any Lender and shall not be responsible to any Lender for
any statements, certificates, warranties or representations made in or in
connection with this Agreement or the other Loan Documents; (iv) shall not have
any duty to ascertain or to inquire as to the performance or observance of any
of the terms, covenants or conditions of this Agreement or the other Loan
Documents on the part of any Person, the existence or possible existence of any
Default or Event of Default, or to inspect the Collateral or other property
(including, without limitation, the books and records) of any Person; (v) shall
not be responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement or the other
Loan Documents or any other instrument or document furnished pursuant hereto or
thereto; and (vi) shall not be deemed to have made any representation or
warranty regarding the existence, value or collectibility of the Collateral, the
existence, priority or perfection of the Collateral Agent's Lien thereon, or any
certificate prepared by any Loan Party in connection therewith, nor shall the
Agents be responsible or liable to the Lenders for any failure to monitor or
maintain any portion of the Collateral. The Agents shall not be liable for any
apportionment or distribution of payments made in good faith pursuant to Section
4.04, and if any such apportionment or distribution is subsequently determined
to have been made in error the sole recourse of any Lender to whom payment was
due but not made, shall be to recover from other Lenders any payment in excess
of the amount which they are determined to be entitled. The Agents may at any
time request instructions from the Lenders with respect to any actions or
approvals which by the terms of this Agreement or of any of the other Loan
Documents the Agents are permitted or required to take or to grant, and if such
instructions are promptly requested, the Agents shall be absolutely entitled to
refrain from taking any action or to withhold any approval under any of the Loan
Documents until they shall have received such instructions from the Required
Lenders. Without limiting the foregoing, no Lender shall have any right of
action whatsoever against any Agent as a result of such Agent acting or
refraining from acting under this Agreement or any of the other Loan Documents
in accordance with the instructions of the Required Lenders.

<PAGE>

          Section 10.04  Reliance. Each Agent shall be entitled to rely upon any
written notices, statements, certificates, orders or other documents or any
telephone message believed by it in good faith 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 or any of the other Loan Documents and its
duties hereunder or thereunder, upon advice of counsel selected by it.

          Section 10.05  Indemnification. To the extent that any Agent or the
L/C Issuer is not reimbursed and indemnified by any Loan Party, the Lenders will
reimburse and indemnify such Agent and the L/C Issuer from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses, advances or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by, or asserted against such Agent
or the L/C Issuer in any way relating to or arising out of this Agreement or any
of the other Loan Documents or any action taken or omitted by such Agent or the
L/C Issuer under this Agreement or any of the other Loan Documents, in
proportion to each Lender's Pro Rata Share, including, without limitation,
advances and disbursements made pursuant to Section 10.08; provided, however,
that no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses, advances
or disbursements for which there has been a final judicial determination that
such liability resulted from such Agent's or the L/C Issuer's gross negligence
or willful misconduct. The obligations of the Lenders under this Section 10.05
shall survive the payment in full of the Loans and the termination of this
Agreement.

          Section 10.06  Agents Individually. With respect to its Pro Rata Share
of the Total Revolving Credit Commitment hereunder and the Loans made by it,
each Agent shall have and may exercise the same rights and powers hereunder and
is subject to the same obligations and liabilities as and to the extent set
forth herein for any other Lender or maker of a Loan. The terms "Lenders" or
"Required Lenders" or any similar terms shall, unless the context clearly
otherwise indicates, include each Agent in its individual capacity as a Lender
or one of the Required Lenders. Each Agent and its Affiliates may accept
deposits from, lend money to, and generally engage in any kind of banking, trust
or other business with the Borrower as if it were not acting as an Agent
pursuant hereto without any duty to account to the other Lenders.

          Section 10.07  Successor Agent. (a) Each Agent may resign from the
performance of all its functions and duties hereunder and under the other Loan
Documents at any time by giving at least 30 Business Days' prior written notice
to the Borrower and each Lender. Such resignation shall take effect upon the
acceptance by a successor Agent of appointment pursuant to clauses (b) and (c)
below or as otherwise provided below.

               (b)  Upon any such notice of resignation, the Required Lenders
shall appoint a successor Agent. Upon the acceptance of any appointment as Agent
hereunder by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations under this Agreement and the other Loan Documents. After any Agent's
resignation hereunder as an Agent, the provisions of this Article X shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
an Agent under this Agreement and the other Loan Documents.

                                     - 102 -

<PAGE>

               (c)  If a successor Agent shall not have been so appointed within
said 30 Business Day period, the retiring Agent, with the consent of the other
Agent shall then appoint a successor Agent who shall serve as an Agent until
such time, if any, as the Required Lenders, with the consent of the other Agent,
appoint a successor Agent as provided above.

          Section 10.08  Collateral Matters.

               (a)  Any Agent may from time to time make such disbursements and
advances ("Agent Advances") which such Agent, in its sole discretion, deems
necessary or desirable to preserve, protect, prepare for sale or lease or
dispose of the Collateral or any portion thereof, to enhance the likelihood or
maximize the amount of repayment by the Borrower of the Loans, Reimbursement
Obligations, Letter of Credit Obligations and other Obligations or to pay any
other amount chargeable to the Borrower pursuant to the terms of this Agreement,
including, without limitation, costs, fees and expenses as described in Section
11.04. The Agent Advances shall be repayable on demand and be secured by the
Collateral. The Agent Advances shall constitute Obligations hereunder which may
be charged to the Loan Account in accordance with Section 4.02. Any Agent making
an Agent Advance shall notify each Lender and the Borrower in writing of each
such Agent Advance, which notice shall include a description of the purpose of
such Agent Advance. Without limitation to its obligations pursuant to Section
10.05, each Lender agrees that it shall make available to such Agent, upon such
Agent's demand, in Dollars in immediately available funds, the amount equal to
such Lender's Pro Rata Share of each such Agent Advance. If such funds are not
made available to such Agent by such Lender, such Agent shall be entitled to
recover such funds on demand from such Lender, together with interest thereon
for each day from the date such payment was due until the date such amount is
paid to such Agent, at the Federal Funds Rate for three Business Days and
thereafter at the Reference Rate.

               (b)  The Lenders hereby irrevocably authorize the Collateral
Agent, at its option and in its discretion, to release any Lien granted to or
held by the Collateral Agent upon any Collateral upon termination of the Total
Revolving Credit Commitment and payment and satisfaction of all Loans,
Reimbursement Obligations, Letter of Credit Obligations, and all other
Obligations which have matured and which the Collateral Agent has been notified
in writing are then due and payable; or constituting property being sold or
disposed of in compliance with the terms of this Agreement and the other Loan
Documents; or constituting property in which the Loan Parties owned no interest
at the time the Lien was granted or at any time thereafter; or if approved,
authorized or ratified in writing by the Lenders. Upon request by the Collateral
Agent at any time, the Lenders will confirm in writing the Collateral Agent's
authority to release particular types or items of Collateral pursuant to this
Section 10.08(b).

               (c)  Without in any manner limiting the Collateral Agent's
authority to act without any specific or further authorization or consent by the
Lenders (as set forth in Section 10.08(b)), each Lender agrees to confirm in
writing, upon request by the Collateral Agent, the authority to release
Collateral conferred upon the Collateral Agent under Section 10.08(b). Upon
receipt by the Collateral Agent of confirmation from the Lenders of its
authority to release any particular item or types of Collateral, and upon prior
written request by any Loan Party, the Collateral Agent shall (and is hereby
irrevocably authorized by the Lenders to) execute such documents as may be
necessary to evidence the release of the Liens granted to the Collateral

                                     - 103 -

<PAGE>

Agent for the benefit of the Lenders upon such Collateral; provided, however,
that (i) the Collateral Agent shall not be required to execute any such document
on terms which, in the Collateral Agent's opinion, would expose the Collateral
Agent to liability or create any obligations or entail any consequence other
than the release of such Liens without recourse or warranty, and (ii) such
release shall not in any manner discharge, affect or impair the Obligations or
any Lien upon (or obligations of any Loan Party in respect of) all interests in
the Collateral retained by any Loan Party.

               (d)  The Collateral Agent shall have no obligation whatsoever to
any Lender to assure that the Collateral exists or is owned by the Loan Parties
or is cared for, protected or insured or has been encumbered or that the Lien
granted to the Collateral Agent pursuant to this Agreement or any other Loan
Document has been properly or sufficiently or lawfully created, perfected,
protected or enforced or is entitled to any particular priority, or to exercise
at all or in any particular manner or under any duty of care, disclosure or
fidelity, or to continue exercising, any of the rights, authorities and powers
granted or available to the Collateral Agent in this Section 10.08 or in any
other Loan Document, it being understood and agreed that in respect of the
Collateral, or any act, omission or event related thereto, the Collateral Agent
may act in any manner it may deem appropriate, in its sole discretion, given the
Collateral Agent's own interest in the Collateral as one of the Lenders and that
the Collateral Agent shall have no duty or liability whatsoever to any other
Lender, except as otherwise provided herein.

          Section 10.09  Agency for Perfection. Each Agent and each Lender
hereby appoints each other Agent and each other Lender as agent and bailee for
the purpose of perfecting the security interests in and liens upon the
Collateral in assets which, in accordance with Article 9 of the Uniform
Commercial Code, can be perfected only by possession or control (or where the
security interest of a secured party with possession or control has priority
over the security interest of another secured party) and each Agent and each
Lender hereby acknowledges that it holds possession of or otherwise controls any
such Collateral for the benefit of the Agents and the Lenders as secured party.
Should the Funding Agent or any Lender obtain possession or control of any such
Collateral, the Funding Agent or such Lender shall notify the Collateral Agent
thereof, and, promptly upon the Collateral Agent's request therefor shall
deliver such Collateral to the Collateral Agent or in accordance with the
Collateral Agent's instructions. Each Loan Party by its execution and delivery
of this Agreement hereby consents to the foregoing.

          Section 11.02  Amendments, Etc. (a) No amendment or waiver of any
provision of this Agreement or any other Loan Document, and no consent to any
departure by any Loan Party therefrom, shall in any event be effective unless

required for the Lenders or any of them to take any action hereunder, (iv) amend

Reserves", "Proved Reserves", "NYMEX Strip Price", "Reserve Report" and "Basis
Differential" that would result in an increase of the Borrowing Base (or in any
definition contained in this Agreement used in connection with the definition of
the foregoing terms that would result in an increase in the Borrowing Base) in
each case, without the written consent of each Lender. Notwithstanding the
foregoing, no amendment, waiver or consent shall, unless in writing and signed
by an Agent, affect the rights or duties of such Agent (but not in its capacity
as a Lender) under this Agreement or the other Loan Documents.

               (b)  The Funding Agent and Foothill, in its capacity as a Lender,
on the one hand, and the Collateral Agent, the Administrative Agent and Ableco
and its Affiliates, in its capacity as a Lender, on the other hand, have
executed an agreement on the Effective Date pursuant to which the Funding Agent,
Foothill, the Collateral Agent, the Administrative Agent and Ableco and its
Affiliates have agreed, among other things, to certain voting arrangements
relative to matters requiring the approval of the Lenders. The rights and duties
of the Funding Agent, Foothill, the Collateral Agent, the Administrative Agent
and Ableco and its Affiliates, with respect to such matters, are subject to such
agreement.

          Section 11.03  No Waiver; Remedies, Etc. No failure on the part of any
Agent or any Lender to exercise, and no delay in exercising, any right hereunder
or under any other Loan Document shall operate as a waiver thereof; nor shall
any single or partial exercise of any right under any Loan Document preclude any
other or further exercise thereof or the exercise of any other right. The rights
and remedies of the Agents and the Lenders provided herein and in the other Loan
Documents are cumulative and are in addition to, and not exclusive of, any
rights or remedies provided by law. The rights of the Agents and the Lenders
under any Loan Document against any party thereto are not conditional or
contingent on any attempt by the Agents and the Lenders to exercise any of their
rights under any other Loan Document against such party or against any other
Person.

          Section 11.04  Expenses; Taxes; Attorneys' Fees. The Borrower will pay

<PAGE>

Section 7.01(b) or the review of any of the agreements, instruments and
documents referred to in Section 7.01(f)), (b) any requested amendments, waivers
or consents to this Agreement or the other Loan Documents whether or not such
documents become effective or are given, (c) the preservation and protection of
any of the Lenders' rights under this Agreement or the other Loan Documents, (d)

Lender by any Person that arises from or relates to this Agreement, any other
Loan Document, the Agents' or the Lenders' claims against any Loan Party, or any
and all matters in connection therewith, (e) the commencement or defense of, or
intervention in, any court proceeding arising from or related to this Agreement
or any other Loan Document, (f) the filing of any petition, complaint, answer,
motion or other pleading by any Agent or any Lender, or the taking of any action
in respect of the Collateral or other security, in connection with this
Agreement or any other Loan Document, (g) the protection, collection, lease,
sale, taking possession of or liquidation of, any Collateral or other security
in connection with this Agreement or any other Loan Document, (h) any attempt to
enforce any Lien or security interest in any Collateral or other security in
connection with this Agreement or any other Loan Document, (i) any attempt to
collect from any Loan Party, (j) the receipt by any Agent or any Lender of any
advice from professionals with respect to any of the foregoing described in
clauses (a) through (m) hereof , (k) all liabilities and costs arising from or
in connection with the past, present or future operations of any Loan Party
involving any damage to real or personal property or natural resources or harm
or injury alleged to have resulted from any Release of Hazardous Materials on,
upon or into such property, (l) any Environmental Liabilities and Costs incurred
in connection with the investigation, removal, cleanup and/or remediation of any
Hazardous Materials present or arising out of the operations of any facility of
any Loan Party or (m) any Environmental Liabilities and Costs incurred in
connection with any Environmental Lien. Without limitation of the foregoing or
any other provision of any Loan Document: (x) the Borrower agrees to pay all
stamp, document, transfer, recording or filing taxes or fees and similar
impositions now or hereafter determined by any Agent or any Lender to be payable
in connection with this Agreement or any other Loan Document, and the Borrower
agrees to save each Agent and each Lender harmless from and against any and all
present or future claims, liabilities or losses with respect to or resulting
from any omission to pay or delay in paying any such taxes, fees or impositions,
(y) the Borrower agrees to pay all broker fees that may become due in connection
with the transactions contemplated by this Agreement and the other Loan
Documents, other than broker fees incurred by any Agent or Lender, and (z) if
the Borrower fails to perform any covenant or agreement contained herein or in
any other Loan Document, any Agent may itself perform or cause performance of
such covenant or agreement, and the expenses of such Agent incurred in
connection therewith shall be reimbursed on demand by the Borrower.

          Section 11.05  Right of Set-off. Upon the occurrence and during the
continuance of any Event of Default, any Agent or any Lender may, and is hereby
authorized to, at any time and from time to time, without notice to any Loan
Party (any such notice being expressly waived by the Loan Parties) and to the
fullest extent permitted by law, set off and apply any and all deposits (general
or special, time or demand, provisional or final) at any time held and other
Indebtedness at any time owing by such Agent or such Lender to or for the credit
or the account of any Loan Party against any and all obligations of the Loan
Parties either now or hereafter existing under any Loan Document, irrespective
of whether or not such Agent or such Lender shall have made any demand hereunder
or thereunder and although such obligations may be contingent or unmatured. Each
Agent and each Lender agrees to notify such Loan Party

                                     - 108 -

<PAGE>

promptly after any such set-off and application made by such Agent or such
Lender, provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of the Agents and the
Lenders under this Section 11.05 are in addition to the other rights and
remedies (including other rights of set-off) which the Agents and the Lenders
may have under this Agreement or any other Loan Documents in law or otherwise.

          Section 11.06  Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining portions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.

          Section 11.07  Assignments and Participations. (a) This Agreement and
the other Loan Documents shall be binding upon and inure to the benefit of each
Loan Party and each Agent and each Lender and their respective successors and
assigns; provided, however, that none of the Loan Parties may assign or transfer
any of its rights hereunder without the prior written consent of each Lender and
any such assignment without the Lenders' prior written consent shall be null and
void.

               (b)  Each Lender may, with the written consent of the Collateral
Agent, assign to one or more other lenders or other entities all or a portion of
its rights and obligations under this Agreement (including, without limitation,
all or a portion of its Commitments, the Loans made by it and its Pro Rata Share
of Letter of Credit Obligations); provided, however, that (i) such assignment is
in an amount which is at least $5,000,000 or a multiple of $1,000,000 in excess
thereof (or the remainder of such Lender's Commitment) (except such minimum
amount shall not apply to an assignment by a Lender to an Affiliate of such
Lender or Related Fund), (ii) the parties to each such assignment shall execute
and deliver to the Collateral Agent, for its acceptance, an Assignment and
Acceptance, together with any promissory note subject to such assignment and
such parties shall deliver to the Collateral Agent a processing and recordation
fee of $5,000 (except the payment of such fee shall not be required in
connection with an assignment by a Lender to an Affiliate of such Lender or
Related Fund) and (iii) no written consent of the Collateral Agent shall be
required in connection with any assignment by a Lender to an Affiliate of such
Lender or a fund or account managed by such Lender or an Affiliate of such
Lender. Upon such execution, delivery and acceptance, from and after the
effective date specified in each Assignment and Acceptance, which effective date
shall be at least three Business Days after the delivery thereof to the
Collateral Agent (or such shorter period as shall be agreed to by the Collateral
Agent and the parties to such assignment), (A) the assignee thereunder shall
become a "Lender" hereunder and, in addition to the rights and obligations
hereunder held by it immediately prior to such effective date, have the rights
and obligations hereunder that have been assigned to it pursuant to such
Assignment and Acceptance and (B) the assigning Lender thereunder shall, to the
extent that rights and obligations hereunder have been assigned by it pursuant
to such Assignment and Acceptance, relinquish its rights and be released from
its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto).

                    (i)   By executing and delivering an Assignment and
Acceptance, the assigning Lender and the assignee thereunder confirm to and
agree with each

                                     - 109 -

<PAGE>

other and the other parties hereto as follows: (A) other than as provided in
such Assignment and Acceptance, the assigning Lender makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
any other Loan Document or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any other Loan Document
furnished pursuant hereto; (B) the assigning Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of any Loan Party or any of its Subsidiaries or the performance or observance by
any Loan Party of any of its obligations under this Agreement or any other Loan
Document furnished pursuant hereto; (C) such assignee confirms that it has
received a copy of this Agreement and the other Loan Documents, together with
such other documents and information it has deemed appropriate to make its own
credit analysis and decision to enter into such Assignment and Acceptance; (D)
such assignee will, independently and without reliance upon the assigning
Lender, any Agent or any Lender and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement and the other Loan
Documents; (E) such assignee appoints and authorizes the Agents to take such
action as agents on its behalf and to exercise such powers under this Agreement
and the other Loan Documents as are delegated to the Agents by the terms hereof
and thereof, together with such powers as are reasonably incidental hereto and
thereto; and (F) such assignee agrees that it will perform in accordance with
their terms all of the obligations which by the terms of this Agreement and the
other Loan Documents are required to be performed by it as a Lender.

                    (ii)  The Collateral Agent shall, on behalf of the Borrower,
maintain, or cause to be maintained at the Payment Office, a copy of each
Assignment and Acceptance delivered to and accepted by it and a register (the
"Register") for the recordation of the names and addresses of the Lenders and
the Commitments of, and principal amount of the Loans (the "Registered Loans")
and Letter of Credit Obligations owing to each Lender from time to time. The
entries in the Register shall be conclusive and binding for all purposes, absent
manifest error, and the Borrower, the Agents and the Lenders shall treat each
Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrower and any Lender at any reasonable time and from time to time upon
reasonable prior notice. In the case of any assignment not reflected in the
Register, the assigning Lender shall maintain a comparable Register.

                    (iii) Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and an assignee, together with any promissory
notes subject to such assignment, the Collateral Agent shall, if the Collateral
Agent consents to such assignment and if such Assignment and Acceptance has been
completed (i) accept such Assignment and Acceptance and (ii) record the
information contained therein in the Register.

                    (iv)  A Registered Loan (and the registered note, if any,
evidencing the same) may be assigned or sold in whole or in part only by
registration of such assignment or sale on the Register (and each registered
note shall expressly so provide). Any assignment or sale of all or part of such
Registered Loan (and the registered note, if any, evidencing the same) may be
effected only by registration of such assignment or sale on the Register,
together with the surrender of the registered note, if any, evidencing the same
duly endorsed by (or accompanied by a written instrument of assignment or sale
duly executed by) the

                                     - 110 -

<PAGE>

holder of such registered note, whereupon, at the request of the designated
assignee(s) or transferee(s), one or more new registered notes in the same
aggregate principal amount shall be issued to the designated assignee(s) or
transferee(s). Prior to the registration of assignment or sale of any Registered
Loan (and the registered note, if any, evidencing the same), the Agents shall
treat the Person in whose name such Registered Loan (and the registered note, if
any, evidencing the same) is registered as the owner thereof for the purpose of
receiving all payments thereon and for all other purposes, notwithstanding
notice to the contrary.

                    (v)   In the event that any Lender sells participations in a
Registered Loan, such Lender shall maintain a register on which it enters the
name of all participants in the Registered Loans held by it (the "Participant
Register"). A Registered Loan (and the registered note, if any, evidencing the
same) may be participated in whole or in part only by registration of such
participation on the Participant Register (and each registered note shall
expressly so provide). Any participation of such Registered Loan (and the
registered note, if any, evidencing the same) may be effected only by the
registration of such participation on the Participant Register.

                    (vi)  Any foreign Person who purchases or is assigned or
participates in any portion of such Registered Loan shall provide the Agents and
the Lender with a completed Internal Revenue Service Form W-8BEN (Certificate of
Foreign Status) or a substantially similar form for such purchaser, participant
or any other affiliate who is a holder of beneficial interests in the Registered
Loan.

               (c)  Each Lender may sell participations to one or more banks or
other entities in or to all or a portion of its rights and obligations under
this Agreement and the other Loan Documents (including, without limitation, all
or a portion of its Commitments, the Loans made by it and its Pro Rata Share of
the Letter of Credit Obligations); provided, that (i) such Lender's obligations
under this Agreement (including without limitation, its Commitments hereunder)
and the other Loan Documents shall remain unchanged; (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations, and the Borrower, the Agents 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 and the other Loan
Documents; and (iii) a participant shall not be entitled to require such Lender
to take or omit to take any action hereunder except (A) action directly
effecting an extension of the maturity dates or decrease in the principal amount
of the Loans or Letter of Credit Obligations, (B) action directly effecting an
extension of the due dates or a decrease in the rate of interest payable on the
Loans or the fees payable under this Agreement, or (C) actions directly
effecting a release of all or a substantial portion of the Collateral or any
Loan Party (except as set forth in Section 10.08 of this Agreement or any other
Loan Document). The Loan Parties agree that each participant shall be entitled
to the benefits of Section 2.08 and Section 4.05 of this Agreement with respect
to its participation in any portion of the Commitments and the Loans as if it
was a Lender.

          Section 11.08  Counterparts. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which shall be deemed to be an original, but all of which taken together
shall constitute one and the same agreement. Delivery of an executed counterpart
of this Agreement by telecopier shall be equally

                                     - 111 -

<PAGE>

as effective as delivery of an original executed counterpart of this Agreement.
Any party delivering an executed counterpart of this Agreement by telecopier
also shall deliver an original executed counterpart of this Agreement but the
failure to deliver an original executed counterpart shall not affect the
validity, enforceability, and binding effect of this Agreement. The foregoing
shall apply to each other Loan Document mutatis mutandis.

          Section 11.09  GOVERNING LAW. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS (UNLESS EXPRESSLY PROVIDED TO THE CONTRARY IN ANOTHER LOAN DOCUMENT IN
RESPECT OF SUCH OTHER LOAN DOCUMENT) SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE
AND TO BE PERFORMED IN THE STATE OF NEW YORK.

          Section 11.10  CONSENT TO JURISDICTION; SERVICE OF PROCESS AND VENUE.
ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK IN THE COUNTY OF
NEW YORK OR OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW
YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH LOAN PARTY HEREBY
IRREVOCABLY ACCEPTS IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY,
THE JURISDICTION OF THE AFORESAID COURTS. EACH LOAN PARTY HEREBY IRREVOCABLY
APPOINTS THE SECRETARY OF STATE OF THE STATE OF NEW YORK, OR SUCH OTHER AGENT AS
MAY BE ACCEPTABLE TO THE AGENTS, AS ITS AGENT FOR SERVICE OF PROCESS IN RESPECT
OF ANY SUCH ACTION OR PROCEEDING AND FURTHER IRREVOCABLY CONSENTS TO THE SERVICE
OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS AND IN ANY SUCH ACTION OR
PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL,
POSTAGE PREPAID, TO THE BORROWER AT ITS ADDRESS FOR NOTICES AS SET FORTH IN
Section 11.01 AND TO THE SECRETARY OF STATE OF THE STATE OF NEW YORK, OR SUCH
OTHER AGENT AS MAY BE ACCEPTABLE TO THE AGENTS, SUCH SERVICE TO BECOME EFFECTIVE
TEN (10) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE
AGENTS AND THE LENDERS TO SERVICE OF PROCESS IN ANY OTHER MANNER PERMITTED BY
LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY LOAN PARTY
IN ANY OTHER JURISDICTION. EACH LOAN PARTY HEREBY EXPRESSLY AND IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW
OR HEREAFTER HAVE TO THE JURISDICTION OR LAYING OF VENUE OF ANY SUCH LITIGATION
BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH
LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT ANY
LOAN PARTY HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY
COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT
PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO
ITSELF OR ITS PROPERTY, EACH LOAN PARTY HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY
IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

          Section 11.11  WAIVER OF JURY TRIAL, ETC. EACH LOAN PARTY, EACH AGENT
AND EACH LENDER HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM CONCERNING ANY RIGHTS UNDER THIS AGREEMENT OR THE
OTHER LOAN DOCUMENTS, OR UNDER ANY AMENDMENT, WAIVER, CONSENT, INSTRUMENT,
DOCUMENT OR OTHER AGREEMENT DELIVERED OR WHICH IN THE FUTURE MAY BE DELIVERED IN
CONNECTION THEREWITH, OR ARISING FROM ANY FINANCING RELATIONSHIP EXISTING IN
CONNECTION WITH THIS AGREEMENT, AND AGREES THAT ANY SUCH ACTION, PROCEEDINGS OR
COUNTERCLAIM SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. EACH LOAN
PARTY CERTIFIES THAT NO OFFICER, REPRESENTATIVE, AGENT OR ATTORNEY OF ANY AGENT
OR ANY LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT ANY AGENT OR ANY
LENDER WOULD NOT, IN THE EVENT OF ANY ACTION, PROCEEDING OR COUNTERCLAIM, SEEK
TO ENFORCE THE FOREGOING WAIVERS. EACH LOAN PARTY HEREBY ACKNOWLEDGES THAT THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE AGENTS AND THE LENDERS ENTERING INTO
THIS AGREEMENT.

          Section 11.12  Consent by the Agents and Lenders. Except as otherwise
expressly set forth herein to the contrary, if the consent, approval,
satisfaction, determination, judgment, acceptance or similar action (an
"Action") of any Agent or any Lender shall be permitted or required pursuant to
any provision hereof or any provision of any other agreement to which any Loan
Party is a party and to which any Agent or any Lender has succeeded thereto,
such Action shall be required to be in writing and may be withheld or denied by
such Agent or such Lender, in its sole discretion, with or without any reason,
and without being subject to question or challenge on the grounds that such
Action was not taken in good faith.

          Section 11.13  No Party Deemed Drafter. Each of the parties hereto
agrees that no party hereto shall be deemed to be the drafter of this Agreement.

          Section 11.14  Reinstatement; Certain Payments. If any claim is ever
made upon any Agent, any Lender or the L/C Issuer for repayment or recovery of
any amount or amounts received by such Agent, such Lender or the L/C Issuer in
payment or on account of any of the Obligations, such Agent, such Lender or the
L/C Issuer shall give prompt notice of such claim to each other Agent and Lender
and the Borrower, and if such Agent, such Lender or the L/C Issuer repays all or
part of such amount by reason of (i) any judgment, decree or order of any court
or administrative body having jurisdiction over such Agent, such Lender or the
L/C Issuer or any of its property, or (ii) any good faith settlement or
compromise of any such claim effected by such Agent, such Lender or the L/C
Issuer with any such claimant, then and in such event each Loan Party agrees
that (A) any such judgment, decree, order, settlement or compromise shall be
binding upon it notwithstanding the cancellation of any Indebtedness hereunder
or under the other Loan Documents or the termination of this Agreement or the
other Loan Documents, and (B) it shall be and remain liable to such Agent, such
Lender or the L/C Issuer hereunder for the amount so repaid or recovered to the
same extent as if such amount had never originally been received by such Agent,
such Lender or the L/C Issuer.

          Section 11.15  Indemnification.

                                     - 113 -

<PAGE>

               (a)  General Indemnity. In addition to each Loan Party's other
Obligations under this Agreement, each Loan Party agrees to, jointly and
severally, defend, protect, indemnify and hold harmless each Agent, each Lender
and the L/C Issuer and all of their respective officers, directors, employees,
attorneys, consultants and agents (collectively called the "Indemnitees") from
and against any and all losses, damages, liabilities, obligations, penalties,
fees, reasonable costs and expenses (including, without limitation, reasonable
attorneys' fees, costs and expenses) incurred by such Indemnitees, whether prior
to or from and after the Effective Date, whether direct, indirect or
consequential, as a result of or arising from or relating to or in connection
with any of the following: (i) the negotiation, preparation, execution or
performance or enforcement of this Agreement, any other Loan Document or of any
other document executed in connection with the transactions contemplated by this
Agreement, (ii) any Agent's or any Lender's furnishing of funds to the Borrower
or the L/C Issuer's issuing of Letters of Credit for the account of the Borrower
under this Agreement or the other Loan Documents, including, without limitation,
the management of any such Loans, the Reimbursement Obligations or the Letter of
Credit Obligations, (iii) any matter relating to the financing transactions
contemplated by this Agreement or the other Loan Documents or by any document
executed in connection with the transactions contemplated by this Agreement or
the other Loan Documents, or (iv) any claim, litigation, investigation or
proceeding relating to any of the foregoing, whether or not any Indemnitee is a
party thereto (collectively, the "Indemnified Matters"); provided, however, that
the Loan Parties shall not have any obligation to any Indemnitee under this
subsection (a) for any Indemnified Matter caused by the gross negligence or
willful misconduct of such Indemnitee, as determined by a final judgment of a
court of competent jurisdiction.

               (b)  Environmental Indemnity. Without limiting Section 11.15(a)
hereof, each Loan Party agrees to, jointly and severally, defend, indemnify, and
hold harmless the Indemnitees against any and all Environmental Liabilities and
Costs and all other claims, demands, penalties, fines, liability (including
strict liability), losses, damages, costs and expenses (including without
limitation, reasonable legal fees and expenses, consultant fees and laboratory
fees), arising out of (i) any Releases or threatened Releases (x) at any
property presently or formerly owned or operated by any Loan Party or any
Subsidiary of any Loan Party, or any predecessor in interest, or (y) of any
Hazardous Materials generated and disposed of by any Loan Party or any
Subsidiary of any Loan Party, or any predecessor in interest; (ii) any
violations of Environmental Laws; (iii) any Environmental Action relating to any
Loan Party or any Subsidiary of any Loan Party, or any predecessor in interest;
(iv) any personal injury (including wrongful death) or property damage (real or
personal) arising out of exposure to Hazardous Materials used, handled,
generated, transported or disposed by any Loan Party or any Subsidiary of any
Loan Party, or any predecessor in interest; and (v) any breach of any warranty
or representation regarding environmental matters made by the Loan Parties in
Section 6.01(r) or the breach of any covenant made by the Loan Parties in
Section 7.01(j). Notwithstanding the foregoing, the Loan Parties shall not have
any obligation to any Indemnitee under this subsection (b) regarding any
potential environmental matter covered hereunder which is caused by the gross
negligence or willful misconduct of such Indemnitee, as determined by a final
judgment of a court of competent jurisdiction.

               (c)  The indemnification for all of the foregoing losses,
damages, fees, costs and expenses of the Indemnitees are chargeable against the
Loan Account. To the extent

                                     - 114 -

<PAGE>

that the undertaking to indemnify, pay and hold harmless set forth in this
Section 11.15 may be unenforceable because it is violative of any law or public
policy, each Loan Party shall, jointly and severally, contribute the maximum
portion which it is permitted to pay and satisfy under applicable law, to the
payment and satisfaction of all Indemnified Matters incurred by the Indemnitees.
The indemnities set forth in this Section 11.15 shall survive the repayment of
the Obligations and discharge of any Liens granted under the Loan Documents.

          Section 11.16  Records. The unpaid principal of and interest on the
Loans, the interest rate or rates applicable to such unpaid principal and
interest, the duration of such applicability, the Commitments, and the accrued
and unpaid fees payable pursuant to Section 2.06 hereof, including, without
limitation, the Unused Line Fee, the Letter of Credit Fee and the fees set forth
in the Fee Letter, shall at all times be ascertained from the records of the
Agents, which shall be conclusive and binding absent manifest error.

          Section 11.17  Binding Effect. This Agreement shall become effective
when it shall have been executed by each Loan Party, each Agent and each Lender
and when the conditions precedent set forth in Section 5.01 hereof have been
satisfied or waived in writing by the Agents, and thereafter shall be binding
upon and inure to the benefit of each Loan Party, each Agent and each Lender,
and their respective successors and assigns, except that the Loan Parties shall
not have the right to assign their rights hereunder or any interest herein
without the prior written consent of each Lender, and any assignment by any
Lender shall be governed by Section 11.07 hereof.

          Section 11.18  Interest. It is the intention of the parties hereto
that each Agent and each Lender shall conform strictly to usury laws applicable
to it. Accordingly, if the transactions contemplated hereby or by any other Loan
Document would be usurious as to any Agent or 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
Agent or such Lender notwithstanding the other provisions of this Agreement),
then, in that event, notwithstanding anything to the contrary in this Agreement
or any other Loan Document or any agreement entered into in connection with or
as security for the Obligations, it is agreed as follows: (i) the aggregate of
all consideration which constitutes interest under law applicable to any Agent
or any Lender that is contracted for, taken, reserved, charged or received by
such Agent or such Lender under this Agreement or any other Loan Document or
agreements or otherwise in connection with the Obligations shall under no
circumstances exceed the maximum amount allowed by such applicable law, any
excess shall be canceled automatically and if theretofore paid shall be credited
by such Agent or such Lender on the principal amount of the Obligations

                                     - 115 -

<PAGE>

(or, to the extent that the principal amount of the Obligations shall have been
or would thereby be paid in full, refunded by such Agent or such Lender, as
applicable, to the Borrower); and (ii) in the event that the maturity of the
Obligations is accelerated by reason of 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
Agent or 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 Agent or such Lender, as
applicable, as of the date of such acceleration or prepayment and, if
theretofore paid, shall be credited by such Agent or such Lender, as applicable,
on the principal amount of the Obligations (or, to the extent that the principal
amount of the Obligations shall have been or would thereby be paid in full,
refunded by such Agent or such Lender to the Borrower). All sums paid or agreed
to be paid to any Agent or any Lender for the use, forbearance or detention of
sums due hereunder shall, to the extent permitted by law applicable to such
Agent or such Lender, be amortized, prorated, allocated and spread throughout
the full 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 an time and from time to time (x) the
amount of interest payable to any Agent or any Lender on any date shall be
computed at the Highest Lawful Rate applicable to such Agent or such Lender
pursuant to this Section 11.18 and (y) in respect of any subsequent interest
computation period the amount of interest otherwise payable to such Agent or
such Lender would be less than the amount of interest payable to such Agent or
such Lender computed at the Highest Lawful Rate applicable to such Agent or such
Lender, then the amount of interest payable to such Agent or such Lender in
respect of such subsequent interest computation period shall continue to be
computed at the Highest Lawful Rate applicable to such Agent or such Lender
until the total amount of interest payable to such Agent or such Lender shall
equal the total amount of interest which would have been payable to such Agent
or such Lender if the total amount of interest had been computed without giving
effect to this Section 11.18.

          For purposes of this Section 11.18, the term "applicable law" shall
mean that law in effect from time to time and applicable to the loan transaction
between the Borrower, on the one hand, and the Agents and the Lenders, on the
other, that lawfully permits the charging and collection of the highest
permissible, lawful non-usurious rate of interest on such loan transaction and
this Agreement, including laws of the State of New York and, to the extent
controlling, laws of the United States of America.

          The right to accelerate the maturity of the Obligations does not
include the right to accelerate any interest that has not accrued as of the date
of acceleration.

          Section 11.19  Confidentiality. Each Agent and each Lender agrees (on
behalf of itself and each of its affiliates, directors, officers, employees and
representatives) to use reasonable precautions to keep confidential, in
accordance with its customary procedures for handling confidential information
of this nature and in accordance with safe and sound practices of comparable
commercial finance companies, any non-public information supplied to it by the
Loan Parties pursuant to this Agreement or the other Loan Documents which is
identified in writing by the Loan Parties as being confidential at the time the
same is delivered to such Person (and which at the time is not, and does not
thereafter become, publicly available or available to such Person from another
source not known to be subject to a confidentiality obligation to such Person
not to disclose such information), provided that nothing herein shall limit the
disclosure of any such information (i) to the extent required by statute, rule,
regulation or judicial process, (ii) to counsel for any Agent or any Lender,
(iii) to examiners, auditors, accountants or Securitization Parties, (iv) in
connection with any litigation to which any Agent or any Lender is a party or
(v) to any assignee or participant (or prospective assignee or participant) so
long as such assignee or participant (or prospective assignee or participant)
first agrees, in writing, to be bound by confidentiality provisions similar in
substance to this Section 11.19. Each Agent and each Lender agrees that, upon
receipt of a request or identification of the requirement for disclosure
pursuant to clause (iv) hereof, it will make reasonable efforts to keep the Loan
Parties

                                     - 116 -

<PAGE>

informed of such request or identification; provided that the each Loan Party
acknowledges that each Agent and each Lender may make disclosure as required or
requested by any Governmental Authority or representative thereof and that each
Agent and each Lender may be subject to review by Securitization Parties or
other regulatory agencies and may be required to provide to, or otherwise make
available for review by, the representatives of such parties or agencies any
such non-public information.

          Section 11.20  No Novation. This Second Amended and Restated Financing
Agreement does not extinguish the obligations for the payment of money
outstanding under the Existing Credit Agreement or discharge or release the
Obligations or the Lien or priority of any mortgage, pledge, security agreement
or any other security therefor. Nothing herein contained shall be construed as a
substitution or novation of the obligations outstanding under the Existing
Credit Agreement or instruments securing the same, which shall remain in full
force and effect, except as modified hereby or by instruments executed
concurrently herewith. Nothing expressed or implied in this Second Amended and
Restated Financing Agreement shall be construed as a release or other discharge
of the Borrower, any Guarantor or any other Loan Party under the Existing Credit
Agreement (including the Security Agreements, the Pledge Agreements and the
Guaranties) from any of its obligations and liabilities as a "Borrower",
"Guarantor" or "Loan Party" thereunder. The Borrower and each other Loan Party
hereby (i) confirms and agrees that each Loan Document to which it is a party
is, and shall continue to be, in full force and effect and is hereby ratified
and confirmed in all respects except that on and after the Effective Date of
this Second Amended and Restated Financing Agreement all references in any such
Loan Document to "the Credit Agreement", "thereto", "thereof", "thereunder" or
words of like import referring to the Existing Credit Agreement shall mean the
Existing Credit Agreement as amended and restated by this Second Amended and
Restated Financing Agreement; and (ii) confirms and agrees that to the extent
that any such Loan Document purports to assign or pledge to the Collateral Agent
for the benefit of the Lenders, or to grant to the Collateral Agent for the
benefit of the Lenders a security interest in or lien on, any collateral as
security for the Obligations of the Borrower, the Guarantors or any other Loan

          Section 11.21  Dutch Security Agreement. (a) Notwithstanding anything
contained in this Agreement and the other Loan Documents and solely for the
purpose of ensuring and preserving the validity and continuity of the security
rights granted and to be granted under or pursuant to (a) the security
agreements governed by the laws of The Netherlands (the "Dutch Security
Agreements"), each of the Lenders and the other parties hereto hereby
acknowledges and consents to (i) the Loan Parties that are party to the Dutch
Security Agreements undertaking therein to pay to the Collateral Agent, in its
individual capacity and not as agent, representative or trustee, amounts which
are equal to and in the currency of the Principal Obligations (as will be
defined in the Dutch Security Agreements) from time to time due in accordance
with the terms of the Principal Obligations (such payment undertaking and the
obligations and liabilities resulting therefrom, as more fully described in the
Dutch Security Agreements, the "Parallel Debt"), and (ii) the security rights
contemplated by the Dutch Security Agreements being granted in favor of the
Collateral Agent in its individual capacity as security for its claims under the

               (b)  The Lenders and the other parties hereto agree that the
Parallel Debt is a claim of the Collateral Agent which is separate and
independent from, and without prejudice to, the claims of the Lenders in respect
of the Principal Obligations, and neither such claim nor the security rights as
contemplated by the Dutch Security Agreements are held jointly with the Lenders,
provided that to the extent any amount is paid to and received by the Collateral
Agent in payment of the Parallel Debt, the total amount due and payable in
respect of the Principal Obligations shall be decreased as if such amount were
received by the Lenders or any of them in payment of the corresponding Principal
Obligations. The Collateral Agent, acting in its individual capacity, hereby
agrees to apply all proceeds that it receives in connection with any enforcement
action taken under or pursuant to the Dutch Security Agreements or otherwise in
satisfaction in whole or in part of the Parallel Debt, mutatis mutandis, in
accordance with the provisions of this Agreement and the other Loan Documents.

          Section 11.22  Integration. This Agreement, together with the other
Loan Documents, reflects the entire understanding of the parties with respect to
the transactions contemplated hereby and shall not be contradicted or qualified
by any other agreement, oral or written, before the date hereof.
