          Section 2.01 Commitment for Advances.

          (a)  Advances.   Each  Lender  severally  agrees,  on  the  terms  and
conditions set forth in this Agreement (including without limitation,  the terms
set forth in Section  3.01),  to make a single  advance term loan on the Closing
Date in  accordance  with its Pro Rata  Share  on a  non-revolving  basis to the
Borrower in an amount equal to such Lender's Commitment. Any Advances which have
been prepaid or repaid may not be reborrowed.

          (b)  Evidence  of  Debt.  The  Advance  made by each  Lender  shall be
evidenced by the records maintained by the Administrative  Agent in the ordinary
course of business.  The records maintained by the Administrative Agent shall be
conclusive  absent  manifest  error of the  amount of the  Advances  made by the
Lenders to the Borrower and the interest and payments thereon. Any failure to so
record or any error in doing so shall not,  however,  limit or otherwise  affect
the obligation of the Borrower hereunder to pay any amount owing with respect to
the  Obligations.  In the event of any conflict between the accounts and records
maintained  by any Lender and the  accounts  and  records of the  Administrative
Agent in respect of such matters, the accounts and records of the Administrative


                                       22


Agent shall  control in the absence of manifest  error.  Upon the request of any
Lender to Borrower made through the  Administrative  Agent,  the Borrower  shall
execute and deliver to such Lender  (through the  Administrative  Agent) a Note,
which, in addition to such records maintained by the Administrative Agent, shall
evidence the obligation of the Borrower to repay the Advance made by such Lender
to the Borrower.  Each Lender may attach schedules to a Note and endorse thereon
the date, Type (if applicable), amount, currency and maturity of its Advance and
payments with respect thereto, but such action or the failure to do so shall not
control over the records thereof maintained by the Administrative Agent.

          Section 2.02 [Reserved].

          Section 2.03 Method of Borrowing.

          (a)  Notice.  Each  Borrowing  shall be made  pursuant  to a Notice of
Borrowing (or by telephone  notice promptly  confirmed in writing by a Notice of
Borrowing),  given not later than  11:00  a.m.  (New York time) (i) on the third
Business  Day  before  the  date of the  proposed  Borrowing,  in the  case of a
Borrowing  comprised of Eurodollar  Rate Advances or (ii) on the Business Day of
the proposed  Borrowing,  in the case of a Borrowing comprised of Reference Rate
Advances,  by the Borrower to the Administrative Agent, which shall in turn give
to each Lender  prompt  notice of such  proposed  Borrowing by  facsimile.  Each
Notice of Borrowing  shall be in writing (by facsimile or otherwise)  specifying
the information  required therein. In the case of a proposed Borrowing comprised
of Eurodollar Rate Advances, the Administrative Agent shall promptly notify each
Lender of the applicable interest rate under Section 2.09(b). Each Lender shall,
before 12:00 noon (New York time) on the date of such Borrowing,  make available
for the account of its Applicable Lending Office to the Administrative  Agent at
its  address  referred  to in  Section  9.02,  or  such  other  location  as the
Administrative Agent may specify by notice to the Lenders, in same day funds, in
the case of a Borrowing,  such Lender's Pro Rata Share of such Borrowing.  After
the  Administrative  Agent's  receipt of such funds and upon  fulfillment of the
applicable  conditions set forth in Article III, the Administrative  Agent shall
make such funds available to the Borrower at its account with the Administrative
Agent.

          (b) Conversions and  Continuations.  The Borrower may elect to Convert
or continue any Borrowing  under this Section 2.03 by delivering an  irrevocable
Notice  of  Conversion  or  Continuation  to  the  Administrative  Agent  at the
Administrative  Agent's  office no later than 11:00 a.m.  (New York time) (i) on
the date  which is at least  three  Business  Days in  advance  of the  proposed
Conversion or continuation date in the case of a Conversion to or a continuation
of a Borrowing  comprised of  Eurodollar  Rate Advances and (ii) on the Business
Day of the  proposed  Conversion,  in the case of a  Conversion  to a  Borrowing
comprised  of  Reference  Rate  Advances.  Each  such  Notice of  Conversion  or
Continuation  shall be in writing (by  facsimile or  otherwise)  specifying  the
information  required therein.  Promptly after receipt of a Notice of Conversion
or Continuation under this Section,  the Administrative Agent shall provide each
Lender with a copy thereof and, in the case of a Conversion to or a continuation
of a Borrowing comprised of Eurodollar Rate Advances,  notify each Lender of the
applicable interest rate under Section 2.09(b).

          (c) Certain  Limitations.  Notwithstanding  anything  to the  contrary
contained in paragraphs (a) and (b) above:

                                       23


          (i) at no time shall there be more than one Interest Period applicable
to  outstanding  Eurodollar  Rate  Advances  and the  Borrower  may  not  select
Eurodollar  Rate  Advances  for any  Borrowing  at any time that a  Default  has
occurred and is continuing;

          (ii) if any Lender shall, at least one Business Day before the date of
any requested Borrowing, Conversion, or continuation,  notify the Administrative
Agent  that any Change in Law makes it  unlawful,  or that any  central  bank or
other Governmental Authority asserts that it is unlawful, for such Lender or its
Applicable  Lending  Office to perform its  obligations  under this Agreement to
make Eurodollar  Rate Advances or to fund or maintain  Eurodollar Rate Advances,
the right of the Borrower to select  Eurodollar  Rate  Advances from such Lender
shall be suspended until such Lender shall notify the Administrative  Agent that
the circumstances  causing such suspension no longer exist, and the Advance made
by such Lender in respect of such Borrowing,  Conversion,  or continuation shall
be a Reference Rate Advance;

          (iii)  if  the  Administrative   Agent  is  unable  to  determine  the
Eurodollar Rate for Eurodollar Rate Advances comprising any requested Borrowing,
the right of the Borrower to select  Eurodollar Rate Advances for such Borrowing
or for any  subsequent  Borrowing  shall be suspended  until the  Administrative
Agent shall notify the Borrower and the Lenders that the  circumstances  causing
such  suspension no longer exist,  and each Advance  comprising  such  Borrowing
shall be a Reference Rate Advance;

          (iv) if the Required  Lenders shall,  at least one Business Day before
the date of any requested  Borrowing,  notify the Administrative  Agent that the
Eurodollar Rate for Eurodollar Rate Advances  comprising such Borrowing will not
adequately  reflect  the  cost  to such  Lenders  of  making  or  funding  their
respective Eurodollar Rate Advances, as the case may be, for such Borrowing, the
right of the Borrower to select  Eurodollar  Rate Advances for such Borrowing or
for any subsequent  Borrowing shall be suspended until the Administrative  Agent
shall notify the Borrower  and the Lenders that the  circumstances  causing such
suspension no longer exist, and each Advance  comprising such Borrowing shall be
a Reference Rate Advance; and

          (v) if the Borrower shall fail to select the duration or  continuation
of any Interest  Period for any Eurodollar  Rate Advances in accordance with the
provisions  contained in the definition of "Interest Period" in Section 1.01 and
paragraph (b) of this Section 2.03, the Administrative  Agent shall forthwith so
notify the Borrower and the Lenders and such Advances shall be made available to
the Borrower on the date of such  Borrowing as Reference Rate Advances or, if an
existing Advance, Convert into Reference Rate Advances.

          (d)  Notices  Irrevocable.  Each  Notice of  Borrowing  and  Notice of
Conversion or Continuation shall be irrevocable and binding on the Borrower.  In
the case of any Borrowing for which the related Notice of Borrowing specifies is
to be comprised of Eurodollar  Rate Advances,  the Borrower shall indemnify each
Lender against any loss,  out-of-pocket cost, or expense incurred by such Lender
as a result of any  failure  by the  Borrower  to  fulfill on or before the date
specified  in such  Notice  of  Borrowing  for  such  Borrowing  the  applicable
conditions  set forth in Article III including any loss  (including  any loss of
anticipated profits),  cost, or expense incurred by reason of the liquidation or
reemployment  of  deposits  or other  funds  acquired by such Lender to fund the


                                       24


Advance to be made by such Lender as part of such  Borrowing  when such Advance,
as a result of such failure, is not made on such date.

          (e) Funding by Lenders;  Presumption by Administrative  Agent.  Unless
the  Administrative  Agent shall have received notice from a Lender prior to the
proposed date of any Borrowing  that such Lender will not make  available to the
Administrative  Agent such Lender's share of such Borrowing,  the Administrative
Agent may assume that such Lender has made such share  available on such date in
accordance  with  paragraph  (a) of this Section 2.03 and may, in reliance  upon
such assumption,  make available to the Borrower a corresponding amount. In such
event,  if a Lender has not in fact made its share of the  applicable  Borrowing
available  to the  Administrative  Agent,  then the  applicable  Lender  and the
Borrower severally agree to pay to the Administrative  Agent forthwith on demand
such corresponding amount with interest thereon, for each day from and including
the date such amount is made available to the Borrower to but excluding the date
of payment to the  Administrative  Agent,  at (i) in the case of a payment to be
made by such Lender, the greater of the Federal Funds Rate and a rate determined
by the  Administrative  Agent  in  accordance  with  banking  industry  rules on
interbank  compensation  and  (ii) in the  case of a  payment  to be made by the
Borrower,  the interest rate  applicable to Base Rate Advances.  If the Borrower
and such Lender shall pay such interest to the Administrative Agent for the same
or an overlapping  period, the Administrative  Agent shall promptly remit to the
Borrower the amount of such  interest  paid by the Borrower for such period.  If
such Lender pays its share of the  applicable  Borrowing  to the  Administrative
Agent,  then the amount so paid shall  constitute such Lender's Advance included
in such Borrowing. Any payment by the Borrower shall be without prejudice to any
claim the Borrower may have against a Lender that shall have failed to make such
payment to the Administrative Agent.

          (f) Lender Obligations  Several. The failure of any Lender to make the
Advance to be made by it as part of any  Borrowing  shall not  relieve any other
Lender  of its  obligation,  if any,  to make  its  Advance  on the date of such
Borrowing. No Lender shall be responsible for the failure of any other Lender to
make the Advance to be made by such other Lender on the date of any Borrowing.

          Section  2.04  Reduction  of the  Commitments.  Upon the making of the
Advances on the on the Closing Date, each Lender's  Commitment  shall be reduced
to $0.

          Section 2.05 Prepayment of Advances.

          (a) Optional.  The Borrower may prepay the  Advances,  after giving by
11:00 a.m. (New York time):  (i) in the case of  Eurodollar  Rate  Advances,  at
least three Business Days' or (ii) in the case of Reference Rate Advances,  same
Business Day's,  irrevocable  prior written notice to the  Administrative  Agent
stating the proposed date and aggregate principal amount of such prepayment.  If
any such notice is given,  the  Borrower  shall  prepay the Advances in whole or
ratably in part in an aggregate  principal  amount equal to the amount specified
in such notice, together with accrued interest to the date of such prepayment on
the principal amount prepaid and amounts,  if any,  required to be paid pursuant
to  Section  2.12  as a  result  of such  prepayment  being  made on such  date;
provided, however, that each partial prepayment shall be made in minimum amounts
of $500,000  and in integral  multiples  of  $100,000  in excess  thereof.  Full
prepayments of any Borrowing are permitted without restriction of amounts.

                                       25


          (b) Mandatory.

              (i) Equity  Issuance.  If the Borrower or any Subsidiary  receives
Equity Issuance  Proceeds,  so long as (a) no Borrowing Base  Deficiency  exists
under the Senior  Credit  Agreement  and (b) no Senior Event of Default  exists,
then  immediately  upon the receipt thereof by the Borrower such Equity Issuance
Proceeds shall be applied ratably, according to the then unpaid amounts thereof,
without  preference  or priority  of any kind among them,  to the payment of the
Advances  then due and payable;  provided that in no event shall the Borrower be
required to make  prepayments  pursuant to this paragraph with respect to Equity
Issuance Proceeds in excess of $100,000,000.

              (ii)  Illegality.  If any Lender shall  notify the  Administrative
Agent and the Borrower that Change in Law makes it unlawful, or that any central
bank or other Governmental Authority asserts that it is unlawful for such Lender
or its Applicable Lending Office to perform its obligations under this Agreement
to maintain  any  Eurodollar  Rate  Advances  of such  Lender  then  outstanding
hereunder,  (i) the Borrower shall, no later than 11:00 a.m. (New York time) (A)
if not  prohibited  by law,  on the last  day of the  Interest  Period  for each
outstanding  Eurodollar  Rate  Advance made by such Lender or (B) if required by
such notice,  on the second  Business Day  following its receipt of such notice,
prepay all of the Eurodollar Rate Advances made by such Lender then outstanding,
together with accrued  interest on the principal  amount  prepaid to the date of
such  prepayment  and amounts,  if any,  required to be paid pursuant to Section
2.12 as a result of such  prepayment  being made on such date,  (ii) such Lender
shall  simultaneously make a Reference Rate Advance to the Borrower on such date
in an amount equal to the  aggregate  principal  amount of the  Eurodollar  Rate
Advances  prepaid to such Lender,  and (iii) the right of the Borrower to select
Eurodollar Rate Advances from such Lender for any subsequent  Borrowing shall be
suspended  until such  Lender  shall  notify the  Administrative  Agent that the
circumstances causing such suspension no longer exist.

         (c)  Interests,  Costs and  Application  of Payments.  Each  prepayment
pursuant to any provision of this Section 2.05 shall be  accompanied  by accrued
interest on the amount prepaid to the date of such  prepayment  and amounts,  if
any, required to be paid pursuant to Section 2.12 as a result of such prepayment
being made on such date. Each prepayment  under this Section 2.05(b) (other than
paragraph  (iv) above)  shall be applied to the  Advances as  determined  by the
Administrative Agent and agreed to by the Lenders in their sole discretion.

         (d) No Additional Right; Ratable Prepayment. The Borrower shall have no
right to prepay any principal  amount of any Advance  except as provided in this
Section  2.05,  and all notices  given  pursuant to this  Section  2.05 shall be
irrevocable and binding upon the Borrower.  Each payment of any Advance pursuant
to this Section 2.05 shall be made in a manner such that all Advances comprising
part of the same Borrowing are paid in whole or ratably in part.

         Section 2.06  Repayment of  Advances.  The Borrower  shall repay to the
Administrative  Agent for the ratable  benefit of the  Lenders  the  outstanding
principal amount of each Advance, together with any accrued interest thereon, on
the Maturity Date or such earlier date pursuant to Section 7.02 or Section 7.03.

         Section 2.07 [Reserved].

                                       26


         Section  2.08 Fees.  The Borrower  agrees to pay to the  Administrative
Agent the fees described in the Fee Letter.

         Section 2.09  Interest.  The Borrower  shall pay interest on the unpaid
principal  amount  of each  Advance  made by each  Lender  from the date of such
Advance  until such  principal  amount shall be paid in full,  at the  following
rates per annum:

         (a)  Reference  Rate  Advances.  If such  Advance is a  Reference  Rate
Advance,  a rate per annum equal at all times to the Adjusted  Reference Rate in
effect from time to time plus the Applicable Margin in effect from time to time,
payable quarterly in arrears on the last day of each March, June, September, and
December and on the date such Reference Rate Advance shall be paid in full.

         (b)  Eurodollar  Rate  Advances.  If such Advance is a Eurodollar  Rate
Advance, a rate per annum equal at all times during the Interest Period for such
Advance to the  Eurodollar  Rate for such  Interest  Period plus the  Applicable
Margin in effect  from time to time,  payable  on the last day of such  Interest
Period  and, in the case of any  Interest  Period  longer  than three  months in
duration,  on the third  monthly  anniversary  of the beginning of such Interest
Period as well as the last day of such Interest Period.

         (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall
pay to  each  Lender,  so  long as any  such  Lender  shall  be  required  under
regulations  of the Federal  Reserve Board to maintain  reserves with respect to
liabilities  or assets  consisting  of or  including  Eurocurrency  Liabilities,
additional  interest  on the unpaid  principal  amount of each  Eurodollar  Rate
Advance of such  Lender,  from the  effective  date of such  Advance  until such
principal  amount is paid in full,  at an  interest  rate per annum equal at all
times to the remainder  obtained by subtracting  (i) the Eurodollar Rate for the
Interest  Period for such Advance from (ii) the rate  obtained by dividing  such
Eurodollar Rate by a percentage  equal to 100% minus the Eurodollar Rate Reserve
Percentage  of such  Lender for such  Interest  Period,  payable on each date on
which interest is payable on such Advance.  Such additional  interest payable to
any Lender  shall be  determined  by such Lender and  notified  to the  Borrower
through the Administrative Agent (such notice to include the calculation of such
additional  interest,  which  calculation  shall be conclusive in the absence of
manifest error).

         (d) Usury Recapture.

              (i) If, with respect to any Lender, the effective rate of interest
contracted for under the Loan Documents,  including the stated rates of interest
and fees contracted for hereunder and any other amounts contracted for under the
Loan Documents which are deemed to be interest,  at any time exceeds the Maximum
Rate,  then the  outstanding  principal  amount of the loans made by such Lender
hereunder  shall bear interest at a rate which would make the effective  rate of
interest for such Lender under the Loan  Documents  equal the Maximum Rate until
the difference between the amounts which would have been due at the stated rates
and the amounts  which were due at the Maximum  Rate (the "Lost  Interest")  has
been recaptured by such Lender.

              (ii)  If,  when  the  loans  and  reimbursement  obligations  made
hereunder are repaid in full, the Lost Interest has not been fully recaptured by
such Lender pursuant to the preceding  paragraph,  then, to the extent permitted


                                       27


by law, for the loans and other credit  extensions made hereunder by such Lender
the interest rates charged under Section 2.09 hereunder  shall be  retroactively
increased  such that the effective rate of interest under the Loan Documents was
at the Maximum  Rate since the  effectiveness  of this  Agreement  to the extent
necessary  to  recapture  the  Lost  Interest  not  recaptured  pursuant  to the
preceding  sentence and, to the extent allowed by law, the Borrower shall pay to
such Lender the amount of the Lost  Interest  remaining to be recaptured by such
Lender.

         Section 2.10 Payments and Computations.

         (a) Payment Procedures. The Borrower shall make each payment under this
Agreement  not later  than  11:00  a.m.  (New York  time) on the day when due in
Dollars to the  Administrative  Agent at 1221 Avenue of the Americas,  New York,
New York  10020  (or such  other  location  as the  Administrative  Agent  shall
designate  in  writing to the  Borrower)  in same day funds  without  deduction,
setoff,  or  counterclaim of any kind. The  Administrative  Agent shall promptly
thereafter  cause to be  distributed  like  funds  relating  to the  payment  of
principal,  interest or fees ratably  (other than amounts  payable solely to the
Administrative Agent or a specific Lender pursuant to Section 2.08(c),  2.09(c),
2.12,  2.13,  2.14,  9.04, 9.05, or 9.06, but after taking into account payments
effected  pursuant to Section  7.04) in  accordance  with each Lender's Pro Rata
Share to the  Lenders  for the account of their  respective  Applicable  Lending
Offices,  and like funds  relating to the payment of any other amount payable to
any Lender to such Lender for the account of its Applicable  Lending Office,  in
each case to be applied in accordance with the terms of this Agreement.

         (b)  Computations.  All computations of interest based on the Reference
Rate and of fees  shall be made by the  Administrative  Agent on the  basis of a
year of 365 or 366 days,  as the case may be, and all  computations  of interest
based on the  Eurodollar  Rate and the  Federal  Funds Rate shall be made by the
Administrative  Agent,  on the basis of a year of 360 days, in each case for the
actual  number of days  (including  the first day, but  excluding  the last day)
occurring  in the period  for which  such  interest  or fees are  payable.  Each
determination  by the  Administrative  Agent of an interest rate or fee shall be
conclusive and binding for all purposes, absent manifest error.

         (c) Non-Business Day Payments.  Whenever any payment 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 extension of time shall in such case be
included in the  computation of payment of interest or fees, as the case may be;
provided,  however, that if such extension would cause payment of interest on or
principal of Eurodollar Rate Advances to be made in the next following  calendar
month, such payment shall be made on the immediately preceding Business Day.

         (d) Payments by Borrower;  Presumptions by Administrative Agent. Unless
the  Administrative  Agent shall have received notice from the Borrower prior to
the date on which any payment is due to the Administrative Agent for the account
of the Lenders  hereunder  that the  Borrower  will not make such  payment,  the
Administrative  Agent may assume that the Borrower has made such payment on such
date  in  accordance  herewith  and  may,  in  reliance  upon  such  assumption,
distribute to the Lenders the amount due. In such event, if the Borrower has not
in fact made such payment, then each of the Lenders severally agrees to repay to
the  Administrative  Agent forthwith on demand the amount so distributed to such


                                       28


Lender,  with  interest  thereon,  for each day from and including the date such
amount  is  distributed  to it to but  excluding  the  date  of  payment  to the
Administrative  Agent,  at the  greater  of the  Federal  Funds  Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules
on interbank compensation.

         Section  2.11  Sharing  of  Payments,  Etc.  If any  Lender  shall,  by
exercising any right of setoff or counterclaim  or otherwise,  obtain payment in
respect  of any  principal  of or  interest  on any of  its  Advances  or  other
obligations  hereunder  resulting  in  such  Lender's  receiving  payment  of  a
proportion of the aggregate  amount of its Advances and accrued interest thereon
or other such  obligations  greater than its pro rata share  thereof as provided
herein,  then the Lender receiving such greater  proportion shall (a) notify the
Administrative  Agent of such fact,  and (b)  purchase  (for cash at face value)
participations  in the Advances and such other obligations of the other Lenders,
or make such other adjustments as shall be equitable, so that the benefit of all
such  payments  shall be shared by the Lenders  ratably in  accordance  with the
aggregate  amount of  principal  of and  accrued  interest  on their  respective
Advances  and  other  amounts  owing  them,  provided  that:  (i)  if  any  such
participations  are purchased and all or any portion of the payment  giving rise
thereto is recovered,  such  participations  shall be rescinded and the purchase
price restored to the extent of such recovery,  without  interest;  and (ii) the
provisions  of this  Section  shall not be construed to apply to (x) any payment
made by the Borrower  pursuant to and in  accordance  with the express  terms of
this Agreement or (y) any payment obtained by a Lender as consideration  for the
assignment of or sale of a participation  in any of its Advances to any assignee
or  participant,  other than to the  Borrower or any  Subsidiary  thereof (as to
which the provisions of this Section shall apply).  The Borrower consents to the
foregoing and agrees,  to the extent it may  effectively do so under  applicable
Legal  Requirement,  that any Lender  acquiring a participation  pursuant to the
foregoing  arrangements  may exercise  against the Borrower rights of setoff and
counterclaim with respect to such  participation as fully as if such Lender were
a direct creditor of the Borrower in the amount of such participation.

         Section  2.12  Breakage  Costs.  If (a) any payment of principal of any
Eurodollar  Rate  Advance  is made  other  than on the last day of the  Interest
Period for such Advance,  whether as a result of any payment pursuant to Section
2.05, the  acceleration of the maturity of the  Obligations  pursuant to Article
VII, or  otherwise,  or (b) the  Borrower  fails to make a principal or interest
payment with respect to any Eurodollar  Rate Advance on the date such payment is
due and payable,  the Borrower shall,  within 10 days of any written demand sent
by any Lender to the  Borrower  through  the  Administrative  Agent,  pay to the
Administrative  Agent for the  account of such  Lender any  amounts  required to
compensate  such  Lender  for any  additional  losses,  out-of-pocket  costs  or
expenses  which  it  may  reasonably  incur  as a  result  of  such  payment  or
nonpayment,  including any loss (including loss of anticipated profits), cost or
expense  incurred by reason of the  liquidation or  reemployment  of deposits or
other funds acquired by any Lender to fund or maintain such Advance.

         Section 2.13 Increased Costs.

         (a) Increased Costs Generally. If any Change in Law shall:

                                       29


         (i) impose,  modify or deem  applicable any reserve,  special  deposit,
compulsory  loan,  insurance  charge or similar  requirement  against assets of,
deposits with or for the account of, or credit  extended or  participated in by,
any Lender  (except any reserve  requirement  reflected in the  Eurodollar  Rate
Reserve Percentage);

         (ii) subject any Lender to any tax of any kind  whatsoever with respect
to this Agreement or any Eurodollar Rate Advance made by it, or change the basis
of  taxation  of  payments  to  such  Lender  in  respect  thereof  (except  for
Indemnified  Taxes or Other Taxes covered by Section 2.14 and the imposition of,
or any change in the rate of, any Excluded Tax payable by such Lender); or

         (iii)  impose on any  Lender or the London  interbank  market any other
condition,  cost or expense affecting this Agreement or Eurodollar Rate Advances
made by such Lender; and the result of any of the foregoing shall be to increase
the cost to such Lender of making or maintaining any Eurodollar Rate Advance (or
of maintaining  its obligation to make any such Advance) or to reduce the amount
of any  sum  received  or  receivable  by  such  Lender  hereunder  (whether  of
principal,  interest or any other amount) then, upon request of such Lender, the
Borrower  will pay to such  Lender  such  additional  amount or  amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.

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

         (c) Certificates for  Reimbursement.  A certificate of a Lender setting
forth the amount or amounts  necessary to compensate  such Lender or its holding
company,  as the case  may be,  as  specified  in  paragraph  (a) or (b) of this
Section and delivered to the Borrower shall be conclusive absent manifest error.
The  Borrower  shall  pay  such  Lender  the  amount  shown  as due on any  such
certificate within 10 days after receipt thereof.

         (d) Delay in  Requests.  Failure  or delay on the part of any Lender to
demand  compensation  pursuant to this Section shall not  constitute a waiver of
such Lender's right to demand such compensation.

         Section 2.14 Taxes.

         (a)  Payments  Free of Taxes.  Any and all payments by or on account of
any obligation of the Borrower  hereunder or under any other Loan Document shall
be  made  free  and  clear  of and  without  reduction  or  withholding  for any


                                       30


Indemnified  Taxes  or  Other  Taxes,  provided  that if the  Borrower  shall be
required  by  applicable  Legal  Requirement  to deduct  any  Indemnified  Taxes
(including any Other Taxes) from such  payments,  then (i) the sum payable shall
be  increased  as  necessary  so  that  after  making  all  required  deductions
(including  deductions applicable to additional sums payable under this Section)
the Administrative Agent or Lender, as the case may be, receives an amount equal
to the sum it would have  received had no such  deductions  been made,  (ii) the
Borrower shall make such  deductions and (iii) the Borrower shall timely pay the
full amount deducted to the relevant  Governmental  Authority in accordance with
applicable Legal Requirement.

         (b)  Payment  of Other  Taxes by the  Borrower.  Without  limiting  the
provisions of paragraph (a) above, the Borrower shall timely pay any Other Taxes
to the relevant  Governmental  Authority in  accordance  with  applicable  Legal
Requirement.

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

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

         (e) Status of  Lenders.  Any  Foreign  Lender  that is  entitled  to an
exemption from or reduction of withholding tax under the law of the jurisdiction
in which the Borrower is resident for tax purposes,  or any treaty to which such
jurisdiction is a party,  with respect to payments  hereunder or under any other
Loan Document shall deliver to the Borrower  (with a copy to the  Administrative
Agent),  at the  time  or  times  prescribed  by  applicable  law or  reasonably
requested by the Borrower or the  Administrative  Agent, such properly completed
and executed  documentation  prescribed  by  applicable  law as will permit such
payments to be made without withholding or at a reduced rate of withholding.  In
addition,  any Lender, if requested by the Borrower or the Administrative Agent,
shall  deliver  such  other  documentation   prescribed  by  applicable  law  or
reasonably  requested by the Borrower or the Administrative Agent as will enable
the Borrower or the Administrative Agent to determine whether or not such Lender
is subject to backup withholding or information reporting requirements.

         Without limiting the generality of the foregoing, in the event that the
Borrower  is resident  for tax  purposes  in the United  States of America,  any
Foreign  Lender shall deliver to the Borrower and the  Administrative  Agent (in


                                       31


such number of copies as shall be requested by the recipient) on or prior to the
date on which such Foreign  Lender  becomes a Lender under this  Agreement  (and
from  time  to  time  thereafter  upon  the  request  of  the  Borrower  or  the
Administrative  Agent, but only if such Foreign Lender is legally entitled to do
so), whichever of the following is applicable:

              (i) duly completed  copies of Internal Revenue Service Form W-8BEN
claiming  eligibility  for  benefits of an income tax treaty to which the United
States of America is a party,

              (ii)  duly  completed  copies of  Internal  Revenue  Service  Form
W-8ECI,

              (iii) in the case of a Foreign Lender claiming the benefits of the
exemption  for  portfolio  interest  under  section  881(c) of the  Code,  (x) a
certificate  to the effect that such Foreign  Lender is not (A) a "bank"  within
the meaning of section  881(c)(3)(A) of the Code, (B) a "10 percent shareholder"
of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a
"controlled foreign  corporation"  described in section 881(c)(3)(C) of the Code
and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

              (iv) any other form  prescribed by  applicable  law as a basis for
claiming exemption from or a reduction in United States Federal  withholding tax
duly  completed  together  with  such  supplementary  documentation  as  may  be
prescribed by applicable law to permit the Borrower to determine the withholding
or deduction required to be made.

         (f)  Treatment of Certain  Refunds.  If the  Administrative  Agent or a
Lender determines, in its sole and reasonable discretion, that it has received a
refund of any Taxes or Other  Taxes as to which it has been  indemnified  by the
Borrower  or with  respect to which the  Borrower  has paid  additional  amounts
pursuant to this  Section,  it shall pay to the Borrower an amount equal to such
refund (but only to the extent of indemnity payments made, or additional amounts
paid,  by the  Borrower  under this  Section  with respect to the Taxes or Other
Taxes giving rise to such refund), net of all reasonable  out-of-pocket expenses
of the  Administrative  Agent or such  Lender,  as the case may be, and  without
interest  (other than any interest paid by the relevant  Governmental  Authority
with respect to such refund),  provided  that the Borrower,  upon the request of
the Administrative Agent or such Lender, agrees to repay the amount paid over to
the  Borrower  (plus any  penalties,  interest or other  charges  imposed by the
relevant  Governmental  Authority) to the Administrative Agent or such Lender in
the event the  Administrative  Agent or such  Lender is  required  to repay such
refund to such Governmental Authority.  This paragraph shall not be construed to
require the Administrative Agent or any Lender to make available its tax returns
(or any other information  relating to its taxes that it deems  confidential) to
the Borrower or any other Person.

                                  ARTICLE III

Borrower's  articles or certificate  of  incorporation  or other  organizational

         Section 4.04 Enforceable  Obligations.  This Agreement,  the Notes, and
the  other  Loan  Documents  to which  the  Borrower  is a party  have been duly

creditors' rights generally and by general principles of equity.

         Section 4.05 Financial Statements.

              (a) The Borrower has delivered to the Administrative Agent and the
Lenders copies of the Financial Statements, and the Financial Statements present
fairly the  financial  condition  of Borrower and its  Subsidiaries  as of their
respective dates and for their respective periods in accordance with GAAP. As of
the  date  of the  Financial  Statements,  there  were  no  material  contingent
obligations, liabilities for taxes, unusual forward or long-term commitments, or
unrealized or anticipated losses of the Borrower, except as disclosed therein in
accordance  with GAAP and  adequate  reserves  for such  items have been made in
accordance with GAAP.

              (b)  All   projections,   estimates,   and  pro  forma   financial
information furnished by the Borrower were prepared on the basis of assumptions,


                                       38


data,  information,  tests, or conditions  believed to be reasonable at the time
such projections, estimates, and pro forma financial information were furnished.

              (c)  Since  the  date of the  Financial  Statements,  no  event or
circumstance  that could  reasonably  be  expected  to cause a Material  Adverse
Change has occurred.

              (d) As of the date of this  Agreement  and after giving  effect to
the  Closing  Date  Acquisition  but before  giving  effect to the making of the

         Section  4.06 True and  Complete  Disclosure.  All factual  information
(excluding  estimates and  projections  such as the  estimates  and  projections
contained in the Engineering Reports) heretofore or contemporaneously  furnished
by or on behalf of the  Borrower  or any of the  Guarantors  in  writing  to any
Lender or the  Administrative  Agent for purposes of or in connection  with this
Agreement,  any other Loan Document or any  transaction  contemplated  hereby or
thereby is, and all other such factual information  hereafter furnished by or on
behalf of the Borrower and the Guarantors in writing to the Administrative Agent
or any of the Lenders  shall be, true and accurate in all  material  respects on
the date as of which such information is dated or certified and does not contain
any untrue  statement  of a  material  fact or omit to state any  material  fact
necessary to make the statements  contained therein not misleading at such time.
All  projections  and estimates  furnished by the Borrower  (including,  without
limitation,  all estimates and projections contained in the Engineering Reports)
were  prepared  on the  basis  of  assumptions,  data,  information,  tests,  or
conditions  believed to be reasonable at the time such  projections,  estimates,
and pro forma financial information were furnished.  This Section 4.06 shall not
be applicable to the Financial  Statements as to which the  representations  and
warranties set forth in Section 4.05 shall be applicable.

         Section 4.07 Litigation; Compliance with Laws.

         (a) Other than as set forth in Schedule  4.07,  there is no pending or,
to the best knowledge of the Borrower, threatened action or proceeding affecting
the Borrower or any of the Guarantors before any court,  Governmental  Authority
or arbitrator  which could  reasonably  be expected to cause a Material  Adverse
Change or which  purports to affect the legality,  validity,  binding  effect or
enforceability  of  this  Agreement,  any  Note,  or any  other  Loan  Document.
Additionally,  there is no pending or, to the best  knowledge  of the  Borrower,
threatened  action or proceeding  instituted  against the Borrower or any of the
Guarantors  which seeks to adjudicate  the Borrower or any of the  Guarantors as
bankrupt or  insolvent,  or seeking  liquidation,  winding  up,  reorganization,
arrangement,  adjustment,  protection, relief, or composition of it or its debts
under any law relating to bankruptcy,  insolvency or reorganization or relief of
debtors,  or seeking  the entry of an order for relief or the  appointment  of a
receiver,  trustee or other similar  official for it or for any substantial part
of its Property, to the extent required herein.

         (b) The Borrower  and its  Subsidiaries  have  complied in all material
respects with all material statutes, rules, regulations, orders and restrictions
of any  Governmental  Authority  having  jurisdiction  over the conduct of their
respective businesses or the ownership of their respective Property.

                                       39


         Section 4.08 Use of Proceeds. The proceeds of the Advances will be used
by the Borrower for the purposes  described in Section 5.09. The Borrower is not
engaged in the business of  extending  credit for the purpose of  purchasing  or
carrying  margin stock (within the meaning of Regulation  U). No proceeds of any
Advance  will be used to  purchase  or carry any margin  stock in  violation  of
Regulation T, U or X.

         Section 4.09  Investment  Company Act.  Neither the Borrower nor any of
the  Guarantors  is an  "investment  company"  or a company  "controlled"  by an
"investment  company" within the meaning of the Investment  Company Act of 1940,
as amended.

         Section 4.10 Federal  Power Act. No Credit Party and no Subsidiary of a
Credit Party is subject to regulation under the Federal Power Act, as amended or
any other Legal  Requirement  which  regulates  the  incurring by such Person of
Debt,  including Legal Requirements  relating to common contract carriers or the
sale of electricity, gas, steam, water or other public utility services.

         Section 4.11 Taxes.

         (a) Reports and  Payments.  All Returns (as defined below in clause (c)
of this Section 4.11) required to be filed by or on behalf of the Borrower,  the
Guarantors, or any member of the Controlled Group (hereafter collectively called
the  "Tax  Group")  have  been  duly  filed on a  timely  basis  or  appropriate
extensions  have been  obtained and such Returns are and will be true,  complete
and  correct,  except  where the  failure  to so file  would  not be  reasonably
expected to cause a Material  Adverse Change;  and all Taxes shown to be payable
on the Returns or on subsequent  assessments with respect thereto will have been
paid in full on a timely  basis,  and no other  Taxes will be payable by the Tax
Group with respect to items or periods  covered by such Returns,  except in each
case to the extent of (i) reserves  reflected  in the  Financial  Statements  or
subsequent  financial statements delivered under Section 5.06 or (ii) taxes that
are being  contested in good faith.  The reserves for accrued Taxes reflected in
the  financial  statements  delivered to the Lenders  under this  Agreement  are
adequate in the aggregate  for the payment of all unpaid  Taxes,  whether or not
disputed,  for the period  ended as of the date thereof and for any period prior
thereto,  and for  which  the Tax  Group  may be  liable  in its own  right,  as
withholding  agent or as a  transferee  of the assets of, or  successor  to, any
Person,  except  for such  Taxes or  reserves  therefor,  the  failure to pay or
provide  for which  does not and would not  reasonably  be  expected  to cause a
Material Adverse Change.

         (b) Taxes  Definition.  "Taxes"  in this  Section  4.11  shall mean all
taxes,  charges,  fees,  levies,  or other  assessments  imposed by any federal,
state,  local, or foreign taxing authority,  including  income,  gross receipts,
excise, real or personal property,  sales,  occupation,  use, service,  leasing,
environmental,   value  added,  transfer,  payroll,  and  franchise  taxes  (and
including  any  interest,  penalties,  or  additions to tax  attributable  to or
imposed on or with respect to any such assessment).

         (c) Returns  Definition.  "Returns" in this Section 4.11 shall mean any
federal,  state,  local, or foreign report,  estimate,  declaration of estimated
Tax,  information  statement  or return  relating to, or required to be filed in
connection  with,  any Taxes,  including any  information  return or report with
respect to backup withholding or other payments of third parties.

                                       40


         Section 4.12 Pension Plans. All Plans are in compliance in all material
respects with all  applicable  provisions  of ERISA.  No  Termination  Event has
occurred  with  respect to any Plan,  and each Plan has  complied  with and been
administered in all material  respects in accordance with applicable  provisions
of ERISA and the Code.  No  "accumulated  funding  deficiency"  (as  defined  in
Section 302 of ERISA) has occurred,  and for plan years after December 31, 2007,
no unpaid minimum required contribution exists, and there has been no excise tax
imposed under  Section 4971 of the Code.  No Reportable  Event has occurred with
respect to any Multiemployer Plan, and each Multiemployer Plan has complied with
and been  administered  in all material  respects in accordance  with applicable
provisions of ERISA and the Code. The present value of all benefits vested under
each Plan (based on the  assumptions  used to fund such Plan) did not, as of the
last annual valuation date applicable thereto, exceed the value of the assets of
such Plan allocable to such vested benefits by more than $1,000,000. Neither the
Borrower  nor any member of the  Controlled  Group has had a complete or partial
withdrawal  from any  Multiemployer  Plan  for  which  there  is any  withdrawal
liability  in  excess  of  $1,000,000.  As of the  most  recent  valuation  date
applicable thereto,  neither the Borrower nor any member of the Controlled Group
would become subject to any liability under ERISA in excess of $1,000,000 if the
Borrower  or any member of the  Controlled  Group has  received  notice that any
Multiemployer Plan is insolvent or in  reorganization.  Based upon GAAP existing
as of the date of this Agreement and current factual circumstances, the Borrower
has no reason to believe that the annual cost during the term of this  Agreement
to the  Borrower  or any  member of the  Controlled  Group  for  post-retirement
benefits to be provided to the current and former  employees  of the Borrower or
any member of the  Controlled  Group under Plans that are welfare  benefit plans
(as defined in Section 3(1) of ERISA)  could,  in the  aggregate,  reasonably be
expected to cause a Material Adverse Change.

         Section 4.13  Condition of Property;  Casualties.  Each of the Borrower
and the Guarantors has good and defensible  title to all of its Properties  free
and clear of all Liens except for Permitted Liens. The material  Properties used
or to be used in the  continuing  operations  of the  Borrower  and  each of the
Guarantors are in good repair,  working order and  condition,  ordinary wear and
tear excepted. Since the date of the Financial Statements,  neither the business
nor the material Properties of the Borrower and each of the Guarantors, taken as
a whole,  has been  materially  and adversely  affected as a result of any fire,
explosion,  earthquake,  flood, drought,  windstorm,  accident,  strike or other
labor disturbance, embargo, requisition or taking of Property or cancellation of
contracts, Permits, or concessions by a Governmental Authority, riot, activities
of armed forces, or acts of God or of any public enemy.

         Section 4.14 No Burdensome Restrictions; No Defaults.

         (a) Neither the Borrower nor any Guarantor is a party to any indenture,
loan,  or credit  agreement  or any lease or other  agreement or  instrument  or
subject to any charter or corporate restriction or provision of applicable Legal
Requirement  that could  reasonably  be  expected  to cause a  Material  Adverse
Change.  Neither the Borrower nor any of its Subsidiaries is in default under or
with respect to any contract, agreement, lease, or other instrument to which the
Borrower or any Subsidiary is a party and which could  reasonably be expected to
cause a Material  Adverse  Change or under any agreement in connection  with any
Debt.  Neither the Borrower nor any of its  Subsidiaries has received any notice


                                       41


of default under any material contract, agreement, lease, or other instrument to
which the Borrower or such Subsidiary is a party.

         (b) No Default has occurred and is continuing.

         Section 4.15 Environmental Condition.

         (a) Permits,  Etc. The  Borrower and the  Guarantors,  or to the extent
that the right of operation is vested in others, such operators on behalf of the
Borrower  and the  Guarantors,  (i)  have  obtained  all  Environmental  Permits
necessary for the ownership and operation of their respective Properties and the
conduct of their respective  businesses  except where the failure to obtain such
Environmental  Permit  could not  reasonably  be  expected  to cause a  Material
Adverse Change; (ii) have at all times been and are in compliance with all terms
and  conditions  of such Permits and with all other  requirements  of applicable
Environmental  Laws  except  where the  failure  to be in  compliance  could not
reasonably  be  expected  to cause a  Material  Adverse  Change;  (iii) have not
received  notice  of  any  material   violation  or  alleged  violation  of  any
Environmental  Law or  Permit;  and  (iv)  are  not  subject  to any  actual  or
contingent  Environmental  Claim,  which could reasonably be expected to cause a
Material Adverse Change.

         (b) Certain  Liabilities.  To the Borrower's actual knowledge,  none of
the  present or  previously  owned or operated  Property of the  Borrower or any
Guarantor or of any of their former Subsidiaries, wherever located: (i) has been
placed  on or  proposed  to be  placed  on the  National  Priorities  List,  the
Comprehensive  Environmental  Response Compensation Liability Information System
list,  or their state or local  analogs,  or have been  otherwise  investigated,
designated,  listed, or identified as a potential site for removal, remediation,
cleanup, closure, restoration, reclamation, or other response activity under any
Environmental  Laws;  (ii) is subject to a Lien,  arising under or in connection
with any  Environmental  Laws,  that attaches to any revenues or to any Property
owned or operated by the Borrower or any of the  Guarantors,  wherever  located,
which could reasonably be expected to cause a Material Adverse Change;  or (iii)
has been the site of any Release of Hazardous  Substances  or  Hazardous  Wastes
from  present  or  past  operations  which  has  caused  at the  site  or at any
third-party  site any  condition  that has  resulted in or could  reasonably  be
expected to result in the need for Response that would cause a Material  Adverse
Change.

         (c) Certain Actions.  Without limiting the foregoing: (i) all necessary
notices  have been  properly  filed,  and no further  action is  required  under
current  Environmental  Law as to each Response or other restoration or remedial
project  undertaken by the Borrower or the Guarantors (or to the extent that the
right of operation is vested in others,  undertaken by such  operators on behalf
of the Borrower or the Guarantors),  or any of their former  Subsidiaries on any
of their  presently or formerly owned or operated  Property and (ii) the present
and, to the Borrower's knowledge,  future liability, if any, of the Borrower and
the Guarantors  which could  reasonably be expected to arise in connection  with
requirements  under  Environmental  Laws will not result in a  Material  Adverse
Change.

         Section 4.16 Permits,  Licenses,  Etc. The Borrower and the Guarantors,
or to the extent that the right of operation is vested in others, such operators
on  behalf of the  Borrower  and the  Guarantors,  possess  all  authorizations,
Permits,  licenses,  patents, patent rights or licenses,  trademarks,  trademark


                                       42


rights,  trade name rights and  copyrights  which are material to the conduct of
their business. The Borrower and the Guarantors, or to the extent that the right
of operation is vested in others,  such  operators on behalf of the Borrower and
the  Guarantors,  manage and operate their business in all material  respects in
accordance with all applicable Legal Requirements and good industry practices.

         Section 4.17 Gas  Contracts.  Other than as set forth in Schedule 4.17,
neither the Borrower nor any of the Guarantors,  as of the date hereof and as of
the Closing  Date:  (a) is obligated  in any  material  respect by virtue of any
prepayment made under any contract  containing a  "take-or-pay"  or "prepayment"
provision or under any similar agreement to deliver  hydrocarbons  produced from
or  allocated  to any of the  Borrower's  and  its  Subsidiaries'  Oil  and  Gas
Properties at some future date without  receiving  full payment  therefor at the
time of delivery,  or (b) has produced gas, in any material amount,  subject to,
and none of the Borrower's and the Guarantors' Oil and Gas Properties is subject
to,  balancing  rights of third  parties or subject to  balancing  duties  under
governmental  requirements,  in each case other than in the  ordinary  course of
business and which prepayments and balancing  rights,  in the aggregate,  do not
result in the Borrower or any Guarantor  having net  aggregate  liability at any
time in excess of an amount equal to 1% of the Proven  Reserves  categorized  as
"proved,  developed and  producing" on the most recently  delivered  Engineering
Report.

         Section 4.18 Liens;  Titles,  Leases,  Etc. None of the Property of the
Borrower or any of the  Guarantors  is subject to any Lien other than  Permitted
Liens or Liens to be released  on the Closing  Date.  On the Closing  Date,  all
governmental  actions and all other filings,  recordings,  registrations,  third
party  consents and other  actions which are necessary to create and perfect the
Liens provided for in the Security Instruments will have been made, obtained and
taken in all relevant  jurisdictions.  All Leases and agreements for the conduct
of business of the Borrower and the Guarantors are valid and subsisting, in full
force and effect and there exists no default or event of default or circumstance
which  with the  giving of notice or lapse of time or both  would give rise to a
default under any such Leases or agreements  which could  reasonably be expected
to  cause  a  Material  Adverse  Change.  Neither  the  Borrower  nor any of the
Guarantors is a party to any agreement or arrangement (other than this Agreement
and the  Security  Instruments),  or  subject to any  order,  judgment,  writ or
decree,  which  either  restricts  or purports to restrict  its ability to grant
Liens to secure the Obligations against their respective assets or Properties.

         Section 4.19 Solvency and Insurance.  Before and after giving effect to
the  making  of the  Advances  and  after  giving  effect  to the  Closing  Date
Acquisition, each of the Borrower and its Subsidiaries is Solvent. Additionally,
each of the Borrower and its Subsidiaries carry insurance required under Section
5.02.

         Section  4.20  Hydrocarbon  Hedge  Agreements.  The  Hydrocarbon  Hedge
Agreements  in effect on the Closing  Date meet the  minimum  volume and minimum
pricing requirements set forth in Section 3.01(p).

         Section 4.21 Material  Agreements.  Schedule 4.21 sets forth a complete
and  correct  list of all  material  agreements,  leases,  indentures,  purchase
agreements,  obligations  in respect of  letters  of credit,  guarantees,  joint
venture agreements, and other instruments in effect or to be in effect as of the
date hereof and as of the Closing  Date  (other than (a) the  Hydrocarbon  Hedge


                                       43


Agreements  and (b) the Closing Date  Acquisition  Instruments  and any material
agreements or instruments disclosed therein) providing for, evidencing, securing
or otherwise relating to any Debt of the Borrower or any of the Guarantors,  and
all obligations of the Borrower or any of the Guarantors to issuers of surety or
appeal bonds issued for account of the Borrower or any such Guarantor,  and such
list  correctly  sets forth the names of the debtor or lessee  and  creditor  or
lessor  with  respect  to the Debt or  lease  obligations  outstanding  or to be
outstanding  and the Property  subject to any Lien  securing  such Debt or lease
obligation.  Also set forth on Schedule  4.21 is a complete  and correct list of
all material agreements and other instruments of the Borrower and the Guarantors
relating to the purchase, transportation by pipeline, gas processing, marketing,
sale and  supply of  natural  gas and  other  Hydrocarbons.  Except as  detailed
otherwise  in Schedule  4.21,  the  Borrower  has  heretofore  delivered  to the
Administrative  Agent and the Lenders a complete  and  correct  copy of all such
material credit agreements,  indentures, purchase agreements, contracts, letters
of credit, guarantees, joint venture agreements, or other instruments, including

                              AFFIRMATIVE COVENANTS

         So long as any Obligation shall remain outstanding, or any Lender shall
have any Commitment hereunder,  the Borrower agrees, unless the Required Lenders
shall otherwise consent in writing, to comply with the following covenants:

         Section 5.01 Compliance with Laws, Etc. The Borrower shall comply,  and
cause each of its  Subsidiaries  to comply,  in all material  respects  with all
Legal  Requirements.  Without  limiting  the  generality  and  coverage  of  the
foregoing,  the Borrower shall comply,  and shall cause each of its Subsidiaries
to comply, in all material  respects,  with all Environmental Laws and all laws,
regulations,  or directives  with respect to equal  employment  opportunity  and
employee  safety  in all  jurisdictions  in which  the  Borrower,  or any of its
Subsidiaries do business;  provided,  however,  that this Section 5.01 shall not
prevent the  Borrower or any of its  Subsidiaries  from,  in good faith and with
reasonable diligence, contesting the validity or application of any such laws or
regulations  by  appropriate  legal  proceedings.   Without  limitation  of  the
foregoing,  the Borrower shall, and shall cause each of its Subsidiaries to, (a)
maintain and possess all authorizations,  Permits, licenses,  trademarks,  trade
names,  rights and copyrights  which are material to the conduct of its business
and (b) obtain, as soon as practicable,  all consents or approvals required from
the  United  States or any states of the  United  States (or other  Governmental
Authorities)  necessary to grant the Administrative Agent an Acceptable Security
Interest in the Borrower's and its Subsidiaries' Oil and Gas Properties.

         Section 5.02 Maintenance of Insurance.

         (a) The Borrower shall,  and shall cause each of its  Subsidiaries  to,
procure and maintain or shall cause to be procured and  maintained  continuously
in effect  policies of  insurance  in form and amounts and issued by  companies,
associations or  organizations  reasonably  satisfactory  to the  Administrative
Agent covering such  casualties,  risks,  perils,  liabilities and other hazards
reasonably required by the Administrative Agent, including business interruption


                                       44


insurance.  In  addition,  the  Borrower  shall,  and  shall  cause  each of its
Subsidiaries to, comply with all requirements  regarding  insurance contained in
the Security Instruments.

         (b) All  certified  copies of policies  or  certificates  thereof,  and
endorsements  and  renewals  thereof  shall be  delivered to and retained by the
Administrative Agent. Unless the Senior Credit Agreement requires otherwise, the
policies of insurance shall either have attached thereto a lender's loss payable
endorsement for the benefit of the  Administrative  Agent, as loss payee in form
reasonably   satisfactory  to  the  Administrative   Agent  or  shall  name  the
Administrative Agent as an additional insured, as applicable. The Borrower shall
furnish the Administrative  Agent with a certificate of insurance or a certified
copy of all policies of insurance  required.  Unless the Senior Credit Agreement
requires  otherwise,  all policies or  certificates of insurance shall set forth
the  coverage,  the limits of  liability,  the name of the  carrier,  the policy
number, and the period of coverage.  Unless the Senior Credit Agreement requires
otherwise,  all  policies of  insurance  required  under the terms  hereof shall
contain  an  endorsement  or  agreement  by the  insurer  that any loss shall be
payable in accordance with the terms of such policy  notwithstanding  any act of
negligence  of the  Borrower,  or a Subsidiary  or any party  holding  under the
Borrower or a Subsidiary  which might  otherwise  result in a forfeiture  of the
insurance and the further agreement of the insurer waiving all rights of setoff,
counterclaim or deductions  against the Borrower and its  Subsidiaries.  Without
limiting the  generality of the foregoing  provisions,  unless the Senior Credit
Agreement  requires  otherwise,   Administrative  Agent  will  be  named  as  an
additional  insured  and  will  be  provided  a  waiver  of  subrogation  on the
Borrower's  general  liability and umbrella  policies.  Unless the Senior Credit
Agreement requires  otherwise,  all such policies shall contain a provision that
notwithstanding any contrary agreements between the Borrower,  its Subsidiaries,
and the  applicable  insurance  company,  such  policies  will not be  canceled,
allowed to lapse without renewal,  surrendered or amended (which provision shall
include any  reduction in the scope or limits of  coverage)  without at least 30
days' prior written notice to the Administrative  Agent unless such is cancelled
for  non-payment of premium and then the  Administrative  Agent will be given 10
days notice of cancellation.  In the event that,  notwithstanding  the "lender's
loss payable endorsement"  requirement of this Section 5.02, the proceeds of any
insurance  policy  described  above are paid to the Borrower or a Subsidiary and
any Obligations are outstanding and the Senior Debt has been  indefeasibly  paid
in full,  the Borrower shall deliver such proceeds to the  Administrative  Agent
immediately upon receipt.

         Section  5.03  Preservation  of  Existence,  Etc.  The  Borrower  shall
preserve  and  maintain,  and cause each of its  Subsidiaries  to  preserve  and
maintain,   its  partnership,   corporate  or  limited  liability  company,   as
applicable, existence, rights, franchises, and privileges in the jurisdiction of
its formation,  and qualify and remain qualified, and cause each such Subsidiary
to qualify and remain  qualified,  as a foreign entity in each  jurisdiction  in
which  qualification  is  necessary  or  desirable  in view of its  business and
operations or the ownership of its Properties,  and, in each case, where failure
to qualify or preserve and maintain its rights and franchises  could  reasonably
be expected to cause a Material Adverse Change.

         Section  5.04  Payment  of  Taxes,  Etc.  The  Borrower  shall  pay and
discharge,  and cause each of its Subsidiaries to pay and discharge,  before the
same shall  become  delinquent,  (a) all taxes,  assessments,  and  governmental
charges or levies imposed upon it or upon its income or profits or Property that
are material in amount,  prior to the date on which penalties attach thereto and


                                       45


(b) all lawful claims that are material in amount which, if unpaid, might by law
become a Lien upon its Property;  provided,  however,  that neither the Borrower
nor any such  Subsidiary  shall be  required to pay or  discharge  any such tax,
assessment, charge, levy, or claim which is being contested in good faith and by
appropriate  proceedings,  and with respect to which reserves in conformity with
GAAP have been provided.

         Section 5.05 Visitation Rights. At any reasonable time and from time to
time,  upon  reasonable   notice,  the  Borrower  shall,  and  shall  cause  its
Subsidiaries to, permit the Administrative  Agent and any Lender or any of their
respective agents or representatives  thereof, to (a) examine and make copies of
and abstracts from the records and books of account of, and visit and inspect at
their  reasonable  discretion  the  Properties  of,  the  Borrower  and any such
Subsidiary,  and (b) discuss the affairs,  finances and accounts of the Borrower
and any such Subsidiary with any of their respective officers or directors.

have any duty to  ascertain  or  inquire  into (i) any  statement,  warranty  or
representation  made in or in connection  with this  Agreement or any other Loan

liability for relying  thereon.  In  determining  compliance  with any condition
hereunder to the making of an Advance that by its terms must be fulfilled to the
satisfaction  of a  Lender,  the  Administrative  Agent  may  presume  that such

Administrative  Agent.  The  Administrative  Agent  and any such  sub-agent  may
perform  any and all of its  duties  and  exercise  its  rights and powers by or
through their  respective  Related Parties.  The exculpatory  provisions of this
Article  shall apply to any such  sub-agent  and to the  Related  Parties of the
Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities  provided
for herein as well as activities as Administrative Agent.

     Section 8.06 Successor  Administrative  Agent. The Administrative Agent may
at any time give notice of its resignation to the Lenders and the Borrower. Upon
receipt of any such notice of resignation,  the Required  Lenders shall have the
right, in consultation with the Borrower, to appoint a successor, which shall be
a bank with an office in New York City or Houston,  Texas or an Affiliate of any
such  bank  with an  office  in New  York  City or  Houston,  Texas.  If no such
successor  shall have been so appointed  by the Required  Lenders and shall have
accepted such appointment within 60 days after the retiring Administrative Agent
gives notice of its resignation,  then the retiring  Administrative Agent may on
behalf of the  Lenders,  appoint a successor  Administrative  Agent  meeting the
qualifications set forth above provided that if the  Administrative  Agent shall
notify the Borrower and the Lenders that no qualifying  Person has accepted such
appointment,  then  such  resignation  shall  nonetheless  become  effective  in
accordance with such notice and (1) the retiring  Administrative  Agent shall be


                                       67


discharged  from its duties and  obligations  hereunder and under the other Loan
Documents (except that in the case of any Collateral held by the  Administrative
Agent on behalf of the Lenders  under any of the Loan  Documents,  the  retiring
Administrative Agent shall continue to hold such Collateral until such time as a
successor   Administrative   Agent   is   appointed)   and  (2)  all   payments,
communications  and  determinations  provided  to be made by, to or through  the
Administrative Agent shall instead be made by or to each Lender directly,  until
such time as the Required  Lenders appoint a successor  Administrative  Agent as
provided  for  above in this  Section.  Upon  the  acceptance  of a  successor's
appointment as Administrative  Agent hereunder,  such successor shall succeed to
and become vested with all of the rights,  powers,  privileges and duties of the
retiring  (or retired)  Administrative  Agent,  and the retiring  Administrative
Agent shall be discharged  from all of its duties and  obligations  hereunder or
under the other Loan Documents (if not already discharged  therefrom as provided
above  in this  Section).  The  fees  payable  by the  Borrower  to a  successor
Administrative  Agent  shall  be the same as those  payable  to its  predecessor
unless  otherwise  agreed  between the  Borrower and such  successor.  After the
retiring  Administrative  Agent's resignation hereunder and under the other Loan
Documents,  the  provisions  of this  Article and  Sections  9.04 and 9.05 shall
continue in effect for the benefit of such retiring  Administrative  Agent,  its
sub-agents and their respective  Related Parties in respect of any actions taken
or omitted to be taken by any of them while the  retiring  Administrative  Agent
was acting as Administrative Agent.

     Section 8.07 Non-Reliance on Administrative  Agent and Other Lenders.  Each
Lender  acknowledges  that it has,  independently  and without reliance upon the
Administrative  Agent or any other  Lender or any of their  Related  Parties and
based on such documents and information as it has deemed  appropriate,  made its
own credit analysis and decision to enter into this Agreement.  Each Lender also
acknowledges  that  it  will,   independently  and  without  reliance  upon  the
Administrative  Agent or any other  Lender or any of their  Related  Parties and
based on such  documents  and  information  as it shall  from  time to time deem
appropriate,  continue to make its own  decisions in taking or not taking action
under or based upon this  Agreement,  any other  Loan  Document  or any  related
agreement or any document furnished hereunder or thereunder.

     Section  8.08  No  Other  Duties,  etc.  Anything  herein  to the  contrary
notwithstanding,  none  of  the  Persons  indentified  as a  Syndication  Agent,
Bookrunner or Arranger on the cover page hereof shall have any powers, duties or
responsibilities under this Agreement or any of the other Loan Documents, except
in  its  capacity,  as  applicable,  as the  Administrative  Agent  or a  Lender
hereunder.

     Section 8.09 Collateral Matters.

     (a) The  Administrative  Agent  is  authorized  on  behalf  of the  Secured
Parties,  without the  necessity  of any notice to or further  consent from such
Secured  Parties,  from time to time,  to take any actions  with  respect to any
Collateral  or  Security  Instruments  which may be  necessary  to  perfect  and
maintain  the  Liens  upon  the  Collateral  granted  pursuant  to the  Security
Instruments.  The Administrative Agent is further authorized (but not obligated)
on behalf of the  Secured  Parties,  without the  necessity  of any notice to or
further consent from the Secured Parties,  from time to time, to take any action
in exigent  circumstances as may be reasonably  necessary to preserve any rights
or  privileges  of the Secured  Parties  under the Loan  Documents or applicable
Legal  Requirements.  Persons that are owed any Lender  Hedging  Obligations  by


                                       68


accepting the benefit of the Liens granted pursuant to the Security  Instruments
hereby agrees to the terms of this paragraph (a).

     (b) The Lenders,  and Persons that are owed any Lender Hedging  Obligations
by  accepting  the  benefit  of the  Liens  granted  pursuant  to  the  Security
Instruments,  hereby  irrevocably  authorize  the  Administrative  Agent  to (i)
release  any  Lien  granted  to or held by the  Administrative  Agent  upon  any
Collateral  (a) upon  termination  of this  Agreement,  termination of all Hedge
Contracts with such Persons, and the payment in full of all outstanding Advances
and all other Obligations  payable under this Agreement and under any other Loan
Document; (b) constituting property sold or to be sold or disposed of as part of
or in connection  with any  disposition  permitted  under this  Agreement or any
other Loan  Document;  (c)  constituting  property in which the  Borrower or any
Subsidiary  owned no  interest  at the time the Lien was  granted or at any time
thereafter;  or  (d)  constituting  property  leased  to  the  Borrower  or  any
Subsidiary  under  a  lease  which  has  expired  or has  been  terminated  in a
transaction  permitted  under this Agreement or is about to expire and which has
not been, and is not intended by the Borrower or such  Subsidiary to be, renewed
or extended;  and (ii) release a Guarantor from its obligations under a Guaranty
and any other  applicable Loan Document if such Person ceases to be a Subsidiary
as a result of a transaction permitted under this Agreement. Upon the request of
the  Administrative  Agent at any time,  the  Secured  Parties  will  confirm in
writing the  Administrative  Agent's  authority to release  particular  types or
items of Collateral pursuant to this Section 8.09.

                                   ARTICLE IX
                                  MISCELLANEOUS

     Section 9.01  Amendments,  Etc. No amendment or waiver of any  provision of
this  Agreement,  the Notes,  or any other  Loan  Document,  nor  consent to any
departure by the  Borrower or any  Subsidiary  therefrom,  shall in any event be
effective unless the same shall be in writing and signed by the Required Lenders
and the Borrower, and then such waiver or consent shall be effective only in the
specific  instance  and for the  specific  purpose  for which  given;  provided,
however, that no amendment, waiver, or consent shall:

     (a)  without the consent of each  Lender:  (i) waive any of the  conditions
specified  in Article  III;  (ii) change any  provision  of this  Section or the
definition of "Required  Lenders" or any other provision  hereof  specifying the

amend  Section 2.11 or any other  provision  of this  Agreement in a manner that
would  alter the pro rata  sharing of  payments  or the pro rata  allocation  of
disbursements  required thereby; (iv) release any Guarantor from its obligations
under any  Guaranty  unless  such  Guarantor  ceases to be a  Subsidiary  of the
Borrower  under a  transaction  permitted  by the terms  hereof;  (v) permit the
Borrower or any  Subsidiary  to enter into any merger or  consolidation  with or
into any other Person or amend  Section  6.04(a);  (vi)  release any  Collateral
securing the Obligations, except as provided in Section 8.09 above; (vii) change
Section  7.06 or any other  provision  of this  Agreement in a manner that would
alter the order of  application  of proceeds set forth in Section  7.06;  (viii)
increase the aggregate Commitments; or (ix) amend or waive any provision of, nor
consent to any departure by any party thereto from, the Intercreditor Agreement;

                                       69


     (b) without the written consent of each Lender directly  affected  thereby,
(i) extend or increase the Commitment of any Lender (or reinstate any Commitment
terminated  pursuant to Section 7.02), (ii) reduce the principal of, or interest
on, the Obligations or any fees or other amounts payable  hereunder or under any
other  Loan  Document,  or (iii)  postpone  any date  fixed for any  payment  of

payable hereunder or extend the Maturity Date;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing  and  signed by the  Administrative  Agent in  addition  to the  Lenders
required above,  affect the rights or duties of the  Administrative  Agent under
this  Agreement or any other Loan Document and (ii) the  Administrative  Agent's
Fee Letter may be  amended,  or rights or  privileges  thereunder  waived,  in a
writing executed only by the parties thereto.

     Section 9.02 Notices, Etc.

     (a)  General.  Except  in the  case of  notices  and  other  communications
expressly  permitted  to be  given by  telephone  (and  except  as  provided  in
paragraph (c) below), all notices and other  communications  provided for herein
shall be in writing and shall be delivered by hand or overnight courier service,
mailed by  certified  or  registered  mail,  sent by  facsimile  or  (subject to
subsection (c) below) electronic mail address as follows:

              (i)  if  to  any   Borrower   or  any  other  Loan  Party  or  the
Administrative Agent, to the address,  facsimile number, electronic mail address
or  telephone  number  specified  for such Person on Schedule I or to such other
address,  facsimile number, electronic mail address or telephone number as shall
be designated by such party in a notice to the other parties; and

              (ii) if to any other  Lender,  to the address,  facsimile  number,
electronic  mail address or  telephone  number  specified in its  Administrative
Questionnaire  or to such  other  address,  facsimile  number,  electronic  mail
address or telephone  number as shall be designated by such party in a notice to
the Administrative Agent.

         (b) Notices sent by hand or  overnight  courier  service,  or mailed by
certified or registered  mail, shall be deemed to have been given when received;
notices sent by  facsimile  shall be deemed to have been given when sent (except
that,  if not given during normal  business  hours for the  recipient,  shall be
deemed to have been given at the opening of business  on the next  Business  Day
for the recipient).  Notices delivered through electronic  communications to the
extent  provided in paragraph (c) below,  shall be effective as provided in said
paragraph  (c). In no event shall a voicemail  message be effective as a notice,
communication or confirmation hereunder.

         (c) Effectiveness of Facsimile Documents and Signatures. Loan Documents
may be transmitted  and/or signed by facsimile.  The  effectiveness  of any such
documents and signatures shall,  subject to applicable Legal Requirements,  have
the same force and effect as  manually-signed  originals and shall be binding on
all Loan Parties,  the Administrative  Agent and the Lenders. The Administrative
Agent may also require that any such  documents and signatures be confirmed by a
manually-signed original thereof; provided, however, that the failure to request
or deliver the same shall not limit the effectiveness of any facsimile  document
or signature.

                                       70


         (d) Limited Use of Electronic Mail. Unless expressly provided otherwise
herein,  notices  and  other  communications  to the  Lenders  hereunder  may be
delivered  or  furnished  by  electronic  communication  (including  e-mail  and
Internet  or  intranet  websites)   pursuant  to  procedures   approved  by  the
Administrative  Agent, provided that the foregoing shall not apply to notices to
any Lender pursuant to Article II, except that, until the  Administrative  Agent
gives notice to the Borrower to the  contrary,  Notices of Borrowing and Notices
of Conversion or Continuation  may be delivered to the  Administrative  Agent by
electronic  communication.  The Administrative Agent or the Borrower may, in its
discretion,  agree to accept notices and other communications to it hereunder by
electronic  communications  pursuant to procedures approved by it, provided that
approval  of  such   procedures   may  be  limited  to  particular   notices  or
communications.  Unless  the  Administrative  Agent  otherwise  prescribes,  (i)
notices  and  other  communications  sent to an e-mail  address  shall be deemed
received  upon the  sender's  receipt of an  acknowledgement  from the  intended
recipient (such as by the "return  receipt  requested"  function,  as available,
return e-mail or other written acknowledgement), provided that if such notice or
other  communication  is not  sent  during  the  normal  business  hours  of the
recipient, such notice or communication shall be deemed to have been sent at the
opening of business on the next Business Day for the recipient, and (ii) notices
or  communications  posted to an Internet or  intranet  website  shall be deemed
received upon the deemed receipt by the intended recipient at its e-mail address
as described in the  foregoing  clause (i) of  notification  that such notice or
communication is available and identifying the website address therefor.

         (e) Reliance by Administrative  Agent and Lenders.  The  Administrative
Agent  and the  Lenders  shall be  entitled  to rely  and act  upon any  notices
(including telephonic Notices of Borrowing) purportedly given by or on behalf of
the  Borrower  even if (i) such  notices  were  not  made in a manner  specified
herein,  were  incomplete  or were not preceded or followed by any other form of
notice  specified  herein,  or (ii) the  terms  thereof,  as  understood  by the
recipient,  varied from any confirmation  thereof.  The BORROWER SHALL INDEMNIFY
THE ADMINISTRATIVE AGENT, EACH LENDER AND THEIR RELATED PARTIES FROM ALL LOSSES,
COSTS,  EXPENSES AND  LIABILITIES  RESULTING FROM THE RELIANCE BY SUCH PERSON ON
EACH NOTICE  PURPORTEDLY  GIVEN BY OR ON BEHALF OF THE BORROWER.  All telephonic
notices  to and  other  communications  with  the  Administrative  Agent  may be
recorded by the  Administrative  Agent,  and each of the parties  hereto  hereby
consents to such recording.

         Section 9.03 No Waiver;  Cumulative Remedies. No failure on the part of
any Lender or the  Administrative  Agent to  exercise,  and no delay by any such
Person in exercising,  any right,  remedy,  power or privilege  hereunder  shall
operate as a waiver  thereof;  nor shall any single or partial  exercise  of any
such right preclude any other or further exercise thereof or the exercise of any
other  right,  remedy,  power or  privilege.  The rights,  remedies,  powers and
privileges  provided in this  Agreement are  cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

         Section  9.04  Costs  and  Expenses.  The  Borrower  shall  pay (i) all
reasonable  out-of-pocket  expenses incurred by the Administrative Agent and its
Affiliates  (including the reasonable fees, charges and disbursements of counsel
for the Administrative  Agent), in connection with the syndication of the credit
facilities  provided  for  herein,  the  preparation,   negotiation,  execution,
delivery and  administration  of this  Agreement and the other Loan Documents or
any  amendments,  modifications  or waivers of the provisions  hereof or thereof


                                       71


(whether  or not the  transactions  contemplated  hereby  or  thereby  shall  be
consummated) and (ii) all out-of-pocket  expenses incurred by the Administrative
Agent or any  Lender  (including  the fees,  charges  and  disbursements  of any
counsel for the  Administrative  Agent or any Lender),  in  connection  with the
enforcement  or protection of its rights (A) in connection  with this  Agreement
and the other Loan Documents, including its rights under this Section, or (B) in
connection  with the Advances made hereunder,  including all such  out-of-pocket
expenses  incurred during any workout,  restructuring or negotiations in respect
of such  Advances.  The foregoing  costs and expenses  shall include all search,
filing,  recording,  appraisal  charges and fees and taxes related thereto,  and
other out-of-pocket  expenses incurred by the Administrative Agent or any Lender
and the  cost of  independent  public  accountants  and  other  outside  experts
retained by the  Administrative  Agent or any Lender. All amounts due under this
Section 9.04 shall be payable within thirty days after demand. The agreements in
this Section shall survive the  termination of the  Commitments and repayment of
all other Obligations.

         Section  9.05   Indemnification.   The  Borrower  shall  indemnify  the
Administrative  Agent (and any sub-agent thereof),  each Lender and each Related
Party  of any of the  foregoing  Persons  (each  such  Person  being  called  an
"Indemnitee")  against,  and hold each  Indemnitee  harmless  from,  any and all
losses, claims,  damages,  liabilities and related expenses (including the fees,
charges  and  disbursements  of any  counsel  for  any  Indemnitee),  and  shall
indemnify and hold harmless each  Indemnitee  from all fees and time charges and
disbursements for attorneys who may be employees of any Indemnitee,  incurred by
any  Indemnitee or asserted  against any Indemnitee by any third party or by the
Borrower or any other Loan Party  arising out of, in  connection  with,  or as a
result of (i) the  execution  or  delivery  of this  Agreement,  any other  Loan
Document or any  agreement or  instrument  contemplated  hereby or thereby,  the
performance by the parties hereto of their respective  obligations  hereunder or
thereunder  or the  consummation  of the  transactions  contemplated  hereby  or
thereby,  (ii) any Advance or the use or proposed use of the proceeds therefrom,
(iii) any actual or alleged  presence or Release of  Hazardous  Materials  on or
from any property owned or operated by the Borrower or any of its  Subsidiaries,
or any Environmental  Liability related in any way to the Borrower or any of its
Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation
or proceeding relating to any of the foregoing,  whether based on contract, tort
or any other theory,  whether brought by a third party or by the Borrower or any
other Loan Party,  and  regardless of whether any Indemnitee is a party thereto,
provided that such indemnity  shall not, as to any  Indemnitee,  be available to
the extent that such losses,  claims,  damages,  liabilities or related expenses
are determined by a court of competent  jurisdiction by final and  nonappealable
judgment to have  resulted from the gross  negligence  or willful  misconduct of
such Indemnitee. All amounts due under this Section 9.05 shall be payable within
ten Business Days after demand  therefor.  The  agreements in this Section shall
survive the  resignation of the  Administrative  Agent,  the  replacement of any
Lender,  the termination of the  Commitments and the repayment,  satisfaction or
discharge of all the other Obligations.

         Section 9.06 Reimbursement by Lenders.  To the extent that the Borrower
for any reason fails to indefeasibly  pay any amount required under Section 9.04
or Section 9.05 to be paid by it to the  Administrative  Agent (or any sub-agent
thereof) or any Related Party of any of the  Administrative  Agent,  each Lender
severally agrees to pay to the  Administrative  Agent (or any such sub-agent) or


                                       72


such Related Party, as the case may be, such Lender's Pro Rata Share (determined
as of the time that the applicable  unreimbursed expense or indemnity payment is
sought)  of such  unpaid  amount,  provided  that the  unreimbursed  expense  or
indemnified loss, claim,  damage,  liability or related expense, as the case may
be, was incurred by or asserted  against the  Administrative  Agent (or any such
sub-agent)  in its capacity as such,  or against any Related Party of any of the
Administrative Agent acting for the Administrative Agent (or any such sub-agent)
in connection with such capacity.  The failure of any Lender to pay its Pro Rata
Share  of such  unpaid  amounts  shall  not  relieve  any  other  Lender  of its
obligation,  if any,  to pay its  respective  share of such unpaid  amounts.  No
Lender shall be  responsible  for the failure of any other Lender to comply with
this  Section.  All amounts due under this Section 9.06 shall be payable  within
ten Business Days after demand  therefor.  THE  AGREEMENTS IN THIS SECTION SHALL
SURVIVE THE  RESIGNATION OF THE  ADMINISTRATIVE  AGENT,  THE  REPLACEMENT OF ANY
LENDER,  THE TERMINATION OF THE  COMMITMENTS AND THE REPAYMENT,  SATISFACTION OR
DISCHARGE OF ALL THE OTHER OBLIGATIONS

         Section  9.07 Waiver of Damages.  To the fullest  extent  permitted  by
applicable  Legal  Requirement,  each Loan Party  shall not  assert,  and hereby
waives,  any claim  against  any  Indemnitee,  on any theory of  liability,  for
special,  indirect,  consequential  or punitive damages (as opposed to direct or
actual  damages)  arising out of, in  connection  with,  or as a result of, this
Agreement,  any other Loan Document or any agreement or instrument  contemplated
hereby, the transactions  contemplated hereby or thereby, any Advance or the use
of the proceeds  thereof.  No Indemnitee shall be liable for any damages arising
from the use by unintended  recipients  of any  information  or other  materials
distributed by it through  telecommunications,  electronic or other  information
transmission  systems  in  connection  with this  Agreement  or the  other  Loan
Documents or the transactions contemplated hereby or thereby.

         Section 9.08 Successors and Assigns.

         (a) Generally. The terms and provisions of this Agreement and the other
Loan  Documents  shall be binding  upon and inure to the  benefit of the parties
hereto and their respective successors and assigns permitted hereby, except that
the  Borrower  may  not  assign  or  otherwise  transfer  any of its  rights  or
obligations  hereunder  without the prior written  consent of each Lender and no
Lender  may  assign or  otherwise  transfer  any of its  rights  or  obligations
hereunder  except (i) to an Eligible  Assignee in accordance with the provisions
of paragraph (b) of this  Section,  (ii) by way of  participation  in accordance
with the provisions of paragraph (d) of this Section,  or (iii) by way of pledge
or assignment of a security  interest  subject to the  restrictions of paragraph
(f) of this Section and any other attempted  assignment or transfer by any party
hereto shall be null and void. Nothing in this Agreement,  expressed or implied,
shall be  construed  to confer upon any Person  (other than the parties  hereto,
their respective  successors and assigns permitted  hereby,  Participants to the
extent  provided in subsection (d) of this Section and, to the extent  expressly
contemplated  hereby,  the Indemnitees) any legal or equitable right,  remedy or
claim under or by reason of this Agreement.

         (b)  Assignments  by  Lenders.  Any  Lender  may  assign to one or more
Eligible  Assignees all or any portion of its rights and obligations  under this
Agreement; provided, however, that

                                       73


              (i) except in the case of an  assignment  of the entire  remaining
amount of the assigning  Lender's  Commitment and the Advances being assigned at
the time owing to it or in the case of an assignment to a Lender or an Affiliate
of a Lender or an Approved Fund with respect to a Lender,  the aggregate  amount
of the Advances of such Lender being assigned  pursuant to each such  assignment
(determined as of the date of the Assignment and Acceptance with respect to such
assignment) shall not be less than $5,000,000.00;

              (ii) each partial  assignment  shall be made as an assignment of a
proportionate  part of all the assigning  Lender's rights and obligations  under
this Agreement with respect to the Advances assigned;

              (iii)  the  parties  to each such  assignment  shall  execute  and
deliver to the  Administrative  Agent,  for its  acceptance and recording in the
Register, an Assignment and Acceptance; and

              (iv) each Eligible  Assignee (other than an Eligible Assignee that
is a Lender or an Affiliate of a Lender) shall pay to the Administrative Agent a
$3,500 processing and recording fee and shall, if it is not a Lender, deliver to
the Administrative Agent an Administrative Questionnaire.

Upon  such  execution,   delivery,  acceptance  and  recording  thereof  by  the
Administrative  Agent pursuant to paragraph (c) of this Section,  from and after
the effective date specified in each Assignment and Acceptance, (A) the Eligible
Assignee  thereunder shall be a party hereto for all purposes and, to the extent
that rights and obligations  hereunder have been assigned to it pursuant to such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
and (B) such 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 such  Lender's  rights  and  obligations  under this
Agreement,  such Lender shall cease to be a party hereto) but shall  continue to
be entitled to the benefits of Sections 2.13,  2.14,  9.04 and 9.05 with respect
to  facts  and  circumstances  occurring  prior  to the  effective  date of such
assignment.  Any  assignment  or transfer  by a Lender of rights or  obligations
under this Agreement  that does not comply with this paragraph  shall be treated
for purposes of this  Agreement as a sale by such Lender of a  participation  in
such rights and obligations in accordance with paragraph (d) of this Section.

         (c) Register. The Administrative Agent shall maintain at its Applicable
Lending  Office  a copy of  each  Assignment  and  Acceptance  delivered  to and
accepted by it and a register for the  recordation of the names and addresses of
the Lenders and the Commitments  of, and principal  amount of the Advances owing
to, each Lender from time to time (the "Register").  The entries in the Register
shall be conclusive and binding for all purposes,  absent  manifest  error,  and
each of the Loan Parties,  the  Administrative  Agent, and the Lenders may treat
each Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this  Agreement.  The Register  shall be available for inspection by
the  Borrower  or any Lender at any  reasonable  time and from time to time upon
reasonable prior notice.

                                       74


         (d) Participations. Any Lender may at any time, without the consent of,
or notice to, the Borrower or the Administrative  Agent, sell  participations to
any Person (other than a natural person or the Borrower or any of any Borrower's
Affiliates or Subsidiaries)  (each, a "Participant") in all or a portion of such
Lender's  rights and/or  obligations  under this  Agreement  (including all or a
portion  of  its  Advances  owing  to  it);  provided  that  (i)  such  Lender's
obligations under this Agreement shall remain unchanged,  (ii) such Lender shall
remain solely  responsible  to the other parties  hereto for the  performance of
such obligations and (iii) the Borrower,  the Administrative Agent and the other
Lenders  shall  continue  to deal  solely  and  directly  with  such  Lender  in
connection with such Lender's rights and obligations  under this Agreement.  Any
agreement or  instrument  pursuant to which a Lender sells such a  participation
shall  provide  that such  Lender  shall  retain the sole right to enforce  this
Agreement and to approve any amendment,  modification or waiver of any provision
of this  Agreement;  provided that such agreement or instrument may provide that
such Lender  will not,  without  the  consent of the  Participant,  agree to any
amendment,  waiver  or other  modification  described  in the first  proviso  to
Section 9.01 that  directly  affects such  Participant.  Subject to the last two
sentences of this paragraph (d),  Borrower agrees that each Participant shall be
entitled to the benefits of, and be bound by the terms of, Sections 2.12,  2.13,
2.14,  9.04,  9.05 and 9.06 to the same  extent  as if it were a Lender  and had
acquired its interest by  assignment  pursuant to paragraph (b) of this Section.
To the extent  permitted by law, each  Participant also shall be entitled to the
benefits of Section 7.04 as though it were a Lender,  provided such  Participant
agrees to be subject to Section 2.11 as though it were a Lender.  A  Participant
shall not be entitled to receive any greater  payment under Section 2.13 or 2.14
than the  applicable  Lender would have been entitled to receive with respect to
the participation sold to such Participant, unless the sale of the participation
to such  Participant  is made  with the  Borrower's  prior  written  consent.  A
Participant  that  would be a Foreign  Lender  if it were a Lender  shall not be
entitled to the  benefits of Section 2.14 unless the Borrower is notified of the
participation  sold to such  Participant and such  Participant  agrees,  for the
benefit of the Borrower, to comply with Section 2.14 as though it were a Lender.

         (e) Pledge to Federal  Reserve Bank.  Any Lender may at any time pledge
or assign a security  interest  in all or any  portion of its rights  under this
Agreement  to  secure  obligations  of such  Lender,  including  any  pledge  or
assignment to secure  obligations  to a Federal  Reserve Bank;  provided that no
such pledge or assignment  shall release such Lender from any of its obligations
hereunder or substitute  any such pledgee or assignee for such Lender as a party
hereto.

         (f) Approved Funds.  Notwithstanding anything to the contrary contained
herein, any Lender that is a Approved Fund may create a security interest in all
or any portion of the Advances  owing to it and the Note,  if any, held by it to
the trustee for holders of obligations owed, or securities  issued, by such Fund
as security for such  obligations or securities,  provided that unless and until
such trustee  actually  becomes a Lender in compliance with the other provisions
of this Section 9.08, (i) no such pledge shall release the pledging  Lender from
any of its obligations  under the Loan Documents and (ii) such trustee shall not
be entitled to exercise any of the rights of a Lender  under the Loan  Documents
even though such trustee may have acquired  ownership rights with respect to the
pledged interest through foreclosure or otherwise.

                                       75


         (g)  Electronic  Execution  of  Assignments.   The  words  "execution,"
"signed," "signature," and words of like import in any Assignment and Acceptance
shall be deemed to include  electronic  signatures  or the keeping of records in
electronic  form,  each of which shall be of the same legal effect,  validity or
enforceability  as a manually  executed  signature  or the use of a  paper-based
recordkeeping  system,  as the case may be, to the extent and as provided for in
any applicable law,  including the Federal  Electronic  Signatures in Global and
National Commerce Act, the New York State Electronic Signatures and Records Act,
or any other  similar  state laws based on the Uniform  Electronic  Transactions
Act.

         Section 9.09 Confidentiality.  Each of the Administrative Agent and the
Lenders agrees to maintain the  confidentiality  of the  Information (as defined
below),  except that Information may be disclosed (a) to its and its Affiliates'
directors,  officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be  informed of the  confidential  nature of such  Information  and
instructed to keep such Information  confidential),  (b) to the extent requested
by any regulatory  authority  purporting to have jurisdiction over it (including
any  self-regulatory  authority,  such as the National  Association of Insurance
Commissioners),  (c) to the extent required by applicable Legal  Requirements or
by any subpoena or similar legal process,  (d) to any other party hereto, (e) in
connection  with the exercise of any remedies  hereunder or under any other Loan
Document or any action or  proceeding  relating to this  Agreement  or any other
Loan Document or the enforcement of rights hereunder or thereunder,  (f) subject
to an agreement  containing  provisions  substantially the same as those of this
Section,  to (i) any assignee of or Participant in, or any prospective  assignee
of or Participant  in, any of its rights or obligations  under this Agreement or
(ii) any actual or  prospective  counterparty  (or its  advisors) to any swap or
derivative  transaction  relating to the Borrower and its obligations,  (g) with
the consent of the  Borrower or (h) to the extent such  Information  (x) becomes
publicly  available  other  than as a result of a breach of this  Section or (y)
becomes  available  to the  Administrative  Agent or any  Lender or any of their
respective  Affiliates on a  nonconfidential  basis from a source other than the
Borrower.  For purposes of this  Section,  "Information"  means all  information
received  from  any  Loan  Party  relating  to any  Loan  Party  or any of their
respective businesses,  other than any such information that is available to the
Administrative Agent or any Lender or any of its Affiliates on a nonconfidential
basis prior to  disclosure  by any Loan  Party,  provided  that,  in the case of
information  received from a Loan Party after the date hereof,  such information
is  clearly  identified  at the time of  delivery  as  confidential.  Any Person
required to maintain  the  confidentiality  of  Information  as provided in this
Section shall be  considered  to have  complied with its  obligation to do so if
such  Person  has   exercised   the  same   degree  of  care  to  maintain   the
confidentiality  of such  Information  as such  Person  would  accord to its own
confidential information in accordance with safe and sound banking practices.

         Section  9.10  Counterparts;   Effectiveness.  This  Agreement  may  be
executed  in  counterparts   (and  by  different  parties  hereto  in  different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. Except as provided in Section
3.01, this Agreement shall become  effective when it shall have been executed by
the Administrative  Agent and when the Administrative  Agent shall have received
counterparts  hereof that, when taken  together,  bear the signatures of each of
the other parties  hereto.  Delivery of an executed  counterpart  of a signature
page of this  Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

                                       76


         Section 9.11 Survival of Representations,  etc. All representations and
warranties  made  hereunder  and in any other Loan  Document  or other  document
delivered  pursuant  hereto or thereto or in  connection  herewith or  therewith
shall   survive  the   execution   and  delivery   hereof  and   thereof.   Such
representations  and  warranties  have  been  or  will  be  relied  upon  by the
Administrative  Agent and each Lender,  regardless of any investigation  made by
the  Administrative  Agent or any Lender or on their behalf and  notwithstanding
that the Administrative  Agent or any Lender may have had notice or knowledge of
any  Default at the time of any  Advance,  and shall  continue in full force and
effect as long as any Advance or any other  Obligation  hereunder  shall  remain
unpaid or unsatisfied.

         Section 9.12  Severability.  If any provision of this  Agreement or the
other Loan Documents is held to be illegal,  invalid or  unenforceable,  (a) the
legality,  validity  and  enforceability  of the  remaining  provisions  of this
Agreement and the other Loan Documents shall not be affected or impaired thereby
and (b) the parties  shall  endeavor in good faith  negotiations  to replace the
illegal,  invalid or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible  to that of the  illegal,  invalid or
unenforceable  provisions.  The  invalidity  of  a  provision  in  a  particular
jurisdiction shall not invalidate or render  unenforceable such provision in any
other jurisdiction.

         Section 9.13 Interest Rate Limitation.  Notwithstanding anything to the
contrary contained in any Loan Document,  the interest paid or agreed to be paid
under  the  Loan   Documents   shall  not  exceed  the  Maximum   Rate.  If  the
Administrative  Agent or any Lender  shall  receive  interest  in an amount that
exceeds the Maximum Rate, the excess  interest shall be applied to the principal
of the  Advances  or, if it  exceeds  such  unpaid  principal,  refunded  to the
Borrower.  In  determining  whether the interest  contracted  for,  charged,  or
received by the Administrative  Agent or a Lender exceeds the Maximum Rate, such
Person  may,  to the extent  permitted  by  applicable  Legal  Requirement,  (a)
characterize  any payment that is not  principal as an expense,  fee, or premium
rather than interest, (b) exclude voluntary prepayments and the effects thereof,
and (c) amortize,  prorate,  allocate,  and spread in equal or unequal parts the
total amount of interest  throughout the  contemplated  term of the  Obligations
hereunder.

         Section 9.14  Governing  Law. This Agreement and each of the other Loan
Documents  shall be governed by and construed in accordance with the laws of the
State of New York and the applicable laws of the United States of America.

         Section 9.15 Submission to  Jurisdiction;  Waiver of Venue;  Service of
Process.

         (a)  Submission to  Jurisdiction.  The Borrower,  the Lenders,  and the
other parties hereto irrevocably and unconditionally submits, for itself and its
property,  to the  nonexclusive  jurisdiction  of the courts of the State of New
York sitting in New York City and of the United  States  District  Court for the
Southern  District  of the State of New York and any  appellate  court  from any
thereof,  in any  action  or  proceeding  arising  out of or  relating  to  this
Agreement or any other Loan Document,  or for  recognition or enforcement of any
judgment,  and each of the parties hereto irrevocably and unconditionally agrees
that all  claims in respect of any such  action or  proceeding  may be heard and
determined in such New York State court or, to the fullest  extent  permitted by
applicable law, in such Federal court.  Each of the parties hereto agrees that a
final  judgment in any such action or proceeding  shall be conclusive and may be


                                       77


enforced in other  jurisdictions  by suit on the judgment or in any other manner
provided by law.  Nothing in this  Agreement or in any other Loan Document shall
affect any right that the Administrative  Agent or any Lender may otherwise have
to bring any action or proceeding  relating to this  Agreement or any other Loan
Document  against the Borrower or any other Loan Party or its  properties in the
courts of any jurisdiction.

         (b) Waiver of Venue.  Each of the  Borrower,  the Lenders and the other
parties hereto  irrevocably and  unconditionally  waives,  to the fullest extent
permitted by applicable  law, any objection that it may now or hereafter have to
the laying of venue of any action or  proceeding  arising  out of or relating to
this  Agreement or any other Loan Document in any court referred to in paragraph
(a) of this Section.  Each of the parties hereto hereby  irrevocably  waives, to
the fullest extent  permitted by applicable  law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

         (c)  Service of  Process.  Each party  hereto  irrevocably  consents to
service of process in the manner provided for notices in Section 9.02 other than
by electronic mail. Nothing in this Agreement will affect the right of any party
hereto to serve process in any other manner permitted by applicable law.

         Section 9.16 Waiver of Jury Trial.  EACH PARTY TO THIS AGREEMENT HEREBY
EXPRESSLY AND IRREVOCABLY  WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LEGAL  REQUIREMENTS,  ANY  RIGHT  IT MAY  HAVE TO  TRIAL  BY  JURY IN ANY  LEGAL
PROCEEDING  DIRECTLY OR INDIRECTLY  ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT OR THE  TRANSACTIONS  CONTEMPLATED  HEREBY OR THEREBY
(WHETHER  BASED ON CONTRACT,  TORT OR ANY OTHER  THEORY).  EACH PARTY HERETO (A)
CERTIFIES  THAT NO  REPRESENTATIVE,  AGENT OR ATTORNEY  OF ANY OTHER  PERSON HAS
REPRESENTED,  EXPRESSLY OR  OTHERWISE,  THAT SUCH OTHER PERSON WOULD NOT, IN THE
EVENT OF LITIGATION,  SEEK TO ENFORCE THE FOREGOING  WAIVER AND (B) ACKNOWLEDGES
THAT IT AND THE OTHER  PARTIES  HERETO  HAVE  BEEN  INDUCED  TO ENTER  INTO THIS
AGREEMENT  AND THE OTHER LOAN  DOCUMENTS  BY,  AMONG  OTHER  THINGS,  THE MUTUAL
WAIVERS  AND  CERTIFICATIONS  IN THIS  SECTION.  EACH  PARTY  HEREBY  AGREES AND
CONSENTS THAT THIS AGREEMENT MAY FILE AN ORIGINAL  COUNTERPART OR A COPY OF THIS
SECTION  WITH ANY COURT AS WRITTEN  EVIDENCE OF THE  CONSENT OF THE  SIGNATORIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

         Section  9.17 USA Patriot  Act.  Each Lender that is subject to the Act
(as  hereinafter  defined) and the  Administrative  Agent (for itself and not on
behalf  of any  Lender)  hereby  notifies  the  Borrower  that  pursuant  to the
requirements  of the USA Patriot Act (Title III of Pub. L. 107-56  (signed  into
law October 26, 2001)) (the "Act"), it is required to obtain,  verify and record
information that identifies the Borrower,  which  information  includes the name
and address of the Borrower and other information that will allow such Lender or
the Administrative Agent, as applicable,  to identify the Borrower in accordance
with the Act.

                                       78


         Section  9.18  Intercreditor  Agreement.  The  Administrative  Agent is
hereby  authorized  on behalf of the Lenders for the Lenders and its  Affiliates
that are Swap Counterparties to enter into the Intercreditor  Agreement.  A copy
of such Intercreditor  Agreement will be made available to each Secured Party on
the  Closing  Date and  thereafter  upon  request.  Each  Lender  and each  Swap
Counterparty  (by  receiving  the  benefits  thereunder  and of the  Collateral)
acknowledges and agrees to the terms of such Intercreditor  Agreement and agrees
that the terms thereof shall be binding on such Secured Party and its successors
and assigns, as if it were a party thereto.

         Section 9.19  Integration.  This Agreement and the other Loan Documents
represent the final  agreement  among the parties and may not be contradicted by
evidence  of  prior,  contemporaneous,  or  subsequent  oral  agreements  of the
parties. There are no unwritten oral agreements among the parties.
