(a)           Each Lender severally agrees, on the
terms and conditions set forth in this Agreement, to make Advances to the
Borrower from time to time on any Business Day during


 


20

















 


the period from the date of
this Agreement until the Commitment Termination Date in an amount for each

Borrowings consisting of Base Rate Advances, be in an aggregate amount not less
than $1,000,000 and in integral multiples of $500,000 in excess thereof, and in
the case of Borrowings consisting of Eurodollar Rate Advances, be in an
aggregate amount not less than $2,000,000 and in integral multiples of
$1,000,000 in excess thereof, and in each case shall consist of Advances of the
same Type made on the same day by the Lenders ratably according to their
respective Commitments.  Within the
limits of each Lender’s Commitment, and subject to the terms of this Agreement,
the Borrower may from time to time borrow, prepay, and reborrow Advances.


 


(b)           The indebtedness of the Borrower to
each Lender resulting from the Advances owing to such Lender shall be evidenced
by a Note of the Borrower payable to the order of such Lender in an amount equal
to such Lender’s Commitment.


 


Section 2.02       Borrowing
Base.


 


(a)           Borrowing Base.  The Borrowing Base as of the Closing Date
has been set by the Administrative Agent and the Lenders and acknowledged by
the Borrower as $70,000,000.  Such
Borrowing Base shall remain in effect until the next redetermination made
pursuant to this Section 2.02.  The
Borrowing Base shall be determined in accordance with the standards set forth
in Section 2.02(d) and is subject to periodic redetermination pursuant to
Sections 2.02(b) and 2.02(c).


 


(b)           Calculation of Borrowing Base.


 


(i)            The Borrower shall deliver to the
Administrative Agent and each of the Lenders on or before April 1, 2003, and
thereafter on or before each February 15, beginning February 15, 2004, an
Independent Engineering Report dated effective as of the immediately preceding
December 31, and such other information as may be reasonably requested by any
Lender with respect to the Oil and Gas Properties included or to be included in
the Borrowing Base.  Within 20 days
after the Administrative Agent and the Lenders’ receipt of such Independent

deliver to each Lender the Administrative Agent’s recommendation for the
redetermined Borrowing Base.  Within 20
days after the Lenders’ receipt of the Administrative Agent’s recommendation,
each Lender shall advise the Administrative Agent whether or not such Lender
agrees with the Administrative Agent’s recommendation and the Borrowing Base
shall be redetermined upon the approval of Majority Lenders (or all of the
Lenders in case of an increase in the Borrowing Base); provided, however,
the failure of any Lender to give such notice within such period of time shall
be deemed to constitute an acceptance of such redetermination. The
Administrative Agent shall promptly notify the Borrower in writing of the
amount of the Borrowing Base as so redetermined; provided, however that the
failure to give such notice shall not affect the validity of any such redetermination.


 


(ii)           The Borrower shall deliver to the
Administrative Agent and each Lender on or before October 1, 2003, and
thereafter on or before each August 15, beginning August 15, 2004, an Internal

21

















 


and such other information as
may be reasonably requested by the Administrative Agent or any Lender with
respect to the Oil and Gas Properties included or to be included in the
Borrowing Base.  Within 20 days after
the Administrative Agent and the Lenders’ receipt of such Internal Engineering
Report and other information, the Administrative Agent shall deliver to each
Lender the Administrative Agent’s recommendation for the redetermined Borrowing
Base.  Within 20 days after the Lenders’
receipt of the Administrative Agent’s recommendation, each Lender shall advise
the Administrative Agent whether or not such Lender agrees with the
Administrative Agent’s recommendation and the Borrowing Base shall be
redetermined upon the approval of Majority Lenders (or all of the Lenders in
case of an increase in the Borrowing Base); provided, however,
the failure of any Lender to give such notice within such period of time shall
be deemed to constitute an acceptance of such redetermination. The
Administrative Agent shall promptly notify the Borrower in writing of the
amount of the Borrowing Base as so redetermined.


 


(iii)          In the event that the Borrower does
not furnish to the Administrative Agent and the Lenders the Independent
Engineering Report, Internal Engineering Report or other information specified
in clauses (i) and (ii) above by the date specified therein, the Administrative
Agent and the Majority Lenders (or all the Lenders in case of an increase in
the Borrowing Base) may nonetheless redetermine the Borrowing Base and
redesignate the Borrowing Base from time-to-time thereafter in their sole
discretion until the Administrative Agent and the Lenders receive the relevant
Independent Engineering Report, Internal Engineering Report, as applicable, or
other information whereupon the Administrative Agent and the Majority Lenders
(or all the Lenders in case of an increase in the Borrowing Base) shall
redetermine the Borrowing Base as otherwise specified in this Section
2.02.  The failure of the Administrative
Agent and the Lenders to redetermine the Borrowing Base and redesignate the
Borrowing Base by the dates specified above shall not affect the validity of
any redetermination and redesignation conducted from time-to-time hereafter.


 


(iv)          Each delivery of an Engineering Report
by the Borrower to the Administrative Agent and the Lenders shall constitute a
representation and warranty by the Borrower to the Administrative Agent and the
Lenders that (A) the Borrower and its Subsidiaries, as applicable, own the Oil
and Gas Properties specified therein free and clear of any Liens (except
Permitted Liens), and (B) on and as of the date of such Engineering Report each
Oil and Gas Property described as “proved developed” therein was developed for
oil and gas, and the wells pertaining to such Oil and Gas Properties that are
described therein as producing wells (“Wells”) were each producing oil
and gas in paying quantities, except for Wells that were utilized as water or
gas injection wells or as water disposal wells.


 


(c)           Interim Redetermination.  In addition to the Borrowing Base
redeterminations provided for in Section 2.02(b), the Majority Lenders (except
that any increase in the Borrowing Base shall require the consent of all the
Lenders) may, either in their sole discretion or at the request of the Borrower
and based on such information as the Administrative Agent and the Lenders deem
relevant (but in accordance with Section 2.02(d)), make additional redeterminations
of the Borrowing Base.  The parties
requesting the redetermination shall give the other parties at least 10 days’
prior written notice that a redetermination of the Borrowing Base pursuant to
this paragraph (c) is to be performed. 
In connection with any redetermination of the Borrowing Base under this
Section 2.02(c), the Borrower shall provide the Administrative


 


22

















 


Agent and the Lenders with such
information regarding the Credit Parties’ business (including, without
limitation, its Oil and Gas Properties, the Proven Reserves, and production
relating thereto) as the Administrative Agent or any Lender may request,
including, in the case of requests for an increase to the Borrowing Base of
$1,000,000 or more, an updated Independent Engineering Report.  The Administrative Agent shall promptly
notify the Borrower in writing of each redetermination of the Borrowing Base
pursuant to this Section 2.02(c) and the amount of the Borrowing Base as so
redetermined.


 


(d)           Standards for Redetermination.  Each redetermination of the Borrowing Base
by the Administrative Agent and the Lenders pursuant to this Section 2.02 shall
be made (i) in the sole discretion of the Administrative Agent and the Lenders
(but in accordance with the other provisions of this Section 2.02(d)), (ii) in
accordance with the Administrative Agent’s and the Lenders’ customary internal
standards and practices for valuing and redetermining the value of Oil and Gas
Properties in connection with reserve based oil and gas loan transactions,
(iii) in conjunction with the most recent Independent Engineering Report or
Internal Engineering Report, as applicable, or other information received by
the Administrative Agent and the Lenders relating to the Proven Reserves of the
Borrower and its Subsidiaries, and (iv) based upon the estimated value of the
Proven Reserves owned by the Borrower and its Subsidiaries as determined by the
Administrative Agent and the Lenders. 
In valuing and redetermining the Borrowing Base, the Administrative
Agent and the Lenders may also consider the business, financial condition, and
Debt obligations of the Borrower and its Subsidiaries and such other factors as
the Administrative Agent and the Lenders customarily deem appropriate.  In that regard, the Borrower acknowledges
that the determination of the Borrowing Base contains an equity cushion (market
value in excess of loan value), which is essential for the adequate protection
of the Administrative Agent and the Lenders. 
No Proven Reserves shall be included or considered for inclusion in the
Borrowing Base unless the Administrative Agent and the Lenders shall have
received, at the Borrower’s expense, evidence of title satisfactory in form and
substance to the Administrative Agent that the Administrative Agent has an
Acceptable Security Interest in the Oil and Gas Properties relating thereto
pursuant to the Security Instruments. 
At all times after the Administrative Agent has given the Borrower
notification of a redetermination of the Borrowing Base under this Section
2.02, the Borrowing Base shall be equal to the redetermined amount or such
lesser amount designated by the Borrower and disclosed in writing to the
Administrative Agent and the Lenders until the Borrowing Base is subsequently
redetermined in accordance with this Section 2.02.

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 Base Rate Advance;


 


24

















 


(iv)          if the Majority 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 Base 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) above, 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 Base
Rate Advances or, if an existing Advance, Convert into Base Rate Advances.


 


(d)           Notices Irrevocable.  Each Notice of Borrowing and Notice of
Conversion or Continuation shall be irrevocable and binding on the Borrower.


 


(e)           Administrative Agent Reliance.  Unless the Administrative Agent shall have
received notice from a Lender before the date of any Borrowing that such Lender
shall not make available to the Administrative Agent such Lender’s Pro Rata
Share of a Borrowing, the Administrative Agent may assume that such Lender has
made its Pro Rata Share of such Borrowing available to the Administrative Agent
on the date of such Borrowing in accordance with this Agreement and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount.  If and to the extent that such Lender shall not have so made its
Pro Rata Share of such Borrowing available to the Administrative Agent, such
Lender and the Borrower severally agree to immediately repay to the
Administrative Agent on demand such corresponding amount, together with
interest on such amount, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the
Administrative Agent, at (i) in the case of the Borrower, the interest rate
applicable on such day to Advances comprising such Borrowing and (ii) in the
case of such Lender, the Federal Funds Rate for such day.  If such Lender shall repay to the
Administrative Agent such corresponding amount and interest as provided above,
such corresponding amount so repaid shall constitute such Lender’s Advance as
part of such Borrowing for purposes of this Agreement even though not made on
the same day as the other Advances comprising such Borrowing.


 


(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.


 


25

















 


Section 2.04       Reduction
of the Commitments.


 


(a)           The Borrower shall have the right,
upon at least five Business Days’ irrevocable notice to the Administrative
Agent, to terminate in whole or reduce ratably in part the unused portion of
the Commitments; provided that each partial reduction shall be in the
aggregate amount of $1,000,000 or in integral multiples of $1,000,000 in excess
thereof.


 


(b)           Any reduction and termination of the
Commitments pursuant to this Section 2.04 shall be applied ratably to each
Lender’s Commitment and shall be permanent, with no obligation of the Lenders
to reinstate such Commitments.


 


Section 2.05       Prepayment
of Advances.


 


(a)           Optional.  The Borrower may prepay the Advances,
without premium or penalty, after giving by 12:00 p.m. (New York time) (i) in
the case of Eurodollar Rate Advances, at least three Business Days’ or (ii) in
the case of Base Rate Advances, on the same Business Day, 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
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 with respect to:  (A) any Eurodollar Rate Advances shall be
applied to Eurodollar Rate Advances comprising part of the same Borrowing; and
(B) any Type of Advances shall be made in $2,500,000 and in integral multiples
of $500,000 in excess thereof (or the remaining aggregate principal balance
outstanding).  Full prepayments of any
Borrowing are permitted without restriction of amounts.


 


(b)           Borrowing Base Deficiency.  If a Borrowing Base Deficiency exists, then
the Administrative Agent shall give the Borrower and the Lenders prompt written
notice thereof.  The Borrower shall
prepay the Advances or, if the Advances have been repaid in full, make deposits
into the Cash Collateral Account to provide cash collateral for the Letter of
Credit Exposure, such that the Borrowing Base deficiency is cured within ninety
(90) days after the date a deficiency notice regarding the Borrowing Base is
received by the Borrower from the Administrative Agent.  Each prepayment pursuant to this Section
2.05(b) 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)
shall be applied to the Advances in accordance with Section 2.10.


 


(c)           Reduction of Commitments.  On the date of each reduction of the
aggregate Commitments pursuant to Section 2.04, the Borrower agrees to make a
prepayment in respect of the outstanding amount of the Advances to the extent,
if any, that the aggregate unpaid principal amount of all Advances plus
the Revolving Letter of Credit Exposure exceeds the lesser of (A) the aggregate
Commitments, as so reduced and (B) the Borrowing Base.  Each prepayment pursuant to this Section
2.05(c) 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


 


26

















 


as a result of such prepayment
being made on such date.  Each
prepayment under this Section 2.05(c) shall be applied to the Advances as
provided in Section 2.10(a).


 


(d)           Illegality.  If any Lender shall notify the Administrative
Agent and the Borrower that the introduction of or any change in or in the
interpretation of any law or regulation makes it unlawful, or that any central
bank or other Governmental Authority asserts that it is unlawful for such
Lender or its Eurodollar 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 12:00 p.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 Base 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 gives notice referred to above
shall notify the Administrative Agent that the circumstances causing such
suspension no longer exist.


 


(e)           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 on the Maturity Date or such earlier date pursuant to Section 7.02 or
Section 7.03.


 


Section 2.07       Letters
of Credit.


 


(a)           Issuance.  From time to time from the date of this
Agreement until 30 days prior to the Commitment Termination Date, at the
request of the Borrower, the Issuing Lender shall, on the terms and conditions
hereinafter set forth, issue, increase, or extend the Expiration Date of, Letters
of Credit for the account of the Borrower on any Business Day.  No Letter of Credit will be issued,
increased, or extended:


 


(i)            if such issuance, increase, or
extension would cause the Letter of Credit Exposure to exceed the lesser of (A)
$5,000,000 and (B) the Unused Commitment Amount;


 


(ii)           unless such Letter of Credit has an
Expiration Date not later than the earlier of (A) 12 months after the date of
issuance thereof (or, if extendable beyond such period, unless such Letter of
Credit is cancelable upon not more than 30 days’ notice given by the Issuing
Lender to the beneficiary of such Letter of Credit) and (B) the Maturity Date;


 


27

















 


(iii)          unless such Letter of Credit Documents
are in form and substance acceptable to the Issuing Lender in its sole
discretion;


 


(iv)          unless such Letter of Credit is a
standby letter of credit not supporting the repayment of indebtedness for
borrowed money of any Person;


 


(v)           unless the Borrower has delivered to
the Issuing Lender a completed and executed Letter of Credit Application; and


 


(vi)          unless such Letter of Credit is
governed by either (B) the Uniform Customs and Practice for Documentary Credits
(1993 Revision), International Chamber of Commerce Publication No.  500 (or any successor to such publication)
or (A) the International Standby Practices 1998, Institute of International
Banking Law & Practice (or any successor to such publication).


 


If the terms of any Letter of Credit Application
referred to in the foregoing clause (v) conflicts with the terms of this
Agreement, the terms of this Agreement shall control.


 


(b)           Participations.  Upon the date of the issuance or increase of
a Letter of Credit, the Issuing Lender shall be deemed to have sold to each
Lender and each Lender shall be deemed to have purchased from the Issuing
Lender a participation in the related Letter of Credit Obligations equal to
such Lender’s Pro Rata Share at such date and such sale and purchase shall
otherwise be in accordance with the terms of this Agreement.  The Issuing Lender shall promptly notify
each Lender by telex, telephone, or telecopy of each Letter of Credit issued,
increased, or extended or converted and the actual dollar amount of such Lender’s
participation in such Letter of Credit; provided, however that the failure to
give such notice shall not affect the validity of any such participation.


 


(c)           Issuing.  Each Letter of Credit shall be issued,
increased, or extended pursuant to a Letter of Credit Application (or by
telephone notice promptly confirmed in writing by a Letter of Credit
Application), given not later than 12:00 p.m. (New York time) on the fifth
Business Day before the date of the proposed issuance, increase, or extension
of the Letter of Credit, and the Issuing Lender shall give to each other Lender
prompt notice thereof by telex, telephone, or telecopy.  Each Letter of Credit Application shall be
given by telecopier or telex, confirmed immediately in writing, specifying the
information required therein.  After the
Issuing Lender’s receipt of such Letter of Credit Application and upon
fulfillment of the applicable conditions set forth in Article III, the Issuing
Lender shall issue, increase, or extend such Letter of Credit for the account
of the Borrower.  Each Letter of Credit
Application shall be irrevocable and binding on the Borrower.


 


(d)           Reimbursement.  The Borrower hereby agrees to pay on demand
to the Issuing Lender an amount equal to any amount paid by the Issuing Lender
under any Letter of Credit; provided that, subject to the terms and conditions
of this Agreement, the Borrower may request a Advance hereunder for the purpose
of satisfying any such reimbursement obligation.  In the event the Issuing Lender makes a payment pursuant to a
request for draw presented under a Letter of Credit and such payment is not
promptly reimbursed by the Borrower pursuant to the preceding sentence, the
Issuing Lender shall give the Administrative Agent notice of the 


 


28

















 


Borrower’s failure to make such
reimbursement and the Administrative Agent shall promptly notify each Lender of
the amount necessary to reimburse the Issuing Lender.  Upon such notice from the Administrative Agent, each Lender shall
promptly reimburse the Issuing Lender for such Lender’s Pro Rata Share of such
amount, and such reimbursement shall be deemed for all purposes of this
Agreement to be a Advance to the Borrower transferred at the Borrower’s request
to the Issuing Lender.  If such
reimbursement is not made by any Lender to the Issuing Lender on the same day
on which the Administrative Agent notifies such Lender to make reimbursement to
the Issuing Lender hereunder, such Lender shall pay interest on its Pro Rata
Share thereof to the Issuing Lender at a rate per annum equal to the Federal
Funds Rate.  The Borrower hereby
unconditionally and irrevocably authorizes, empowers, and directs the
Administrative Agent and the Lenders to record and otherwise treat such
reimbursements to the Issuing Lender as Base Rate Advances under a Borrowing
requested by the Borrower to reimburse the Issuing Lender which have been
transferred to the Issuing Lender at the Borrower’s request.


 


(e)           Obligations Unconditional.  The obligations of the Borrower under this
Agreement in respect of each Letter of Credit shall be unconditional and
irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including, without limitation, the following
circumstances:


 


(i)            any lack of validity or
enforceability of any Letter of Credit Documents;


 


(ii)           any amendment or waiver of, or any
consent to or departure from, any Letter of Credit Documents;


 


(iii)          the existence of any claim, set-off,
defense, or other right which the Borrower may have at any time against any
beneficiary or transferee of such Letter of Credit (or any Persons for whom any
such beneficiary or any such transferee may be acting), the Issuing Lender, or
any other person or entity, whether in connection with this Agreement, the transactions
contemplated in this Agreement or in any Letter of Credit Documents, or any
unrelated transaction;


 


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


 


(v)           payment by the Issuing Lender under
such Letter of Credit against presentation of a draft or certificate which does
not comply with the terms of such Letter of Credit; or


 


(vi)          any other circumstance or happening
whatsoever, whether or not similar to any of the foregoing.


 


provided,
however, that nothing contained in this paragraph (e) shall be deemed to
constitute a waiver of any remedies of the Borrower in connection with the Letters
of Credit or the Borrower’s rights under Section 2.07(f) below.


 


29

















 


 


(f)            Liability of Issuing Lender.  The Borrower assumes all risks of the acts
or omissions of any beneficiary or transferee of any Letter of Credit with
respect to its use of such Letter of Credit. 
Neither the Issuing Lender nor any of its officers or directors shall be
liable or responsible for:


 


(i)            the use which may be made of any
Letter of Credit or any acts or omissions of any beneficiary or transferee in
connection therewith;


 


(ii)           the validity, sufficiency, or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent, or
forged;


 


(iii)          payment by the Issuing Lender against
presentation of documents which do not comply with the terms of a Letter of
Credit, including failure of any documents to bear any reference or adequate
reference to the relevant Letter of Credit; or


 


(iv)          any other circumstances whatsoever in
making or failing to make payment under any Letter of Credit (including the Issuing Lender’s own negligence),


 


except
that the Borrower shall have a claim against the Issuing Lender, and the
Issuing Lender shall be liable to the Borrower, to the extent of any direct, as
opposed to consequential, damages suffered by the Borrower which the Borrower
proves were caused by the Issuing Lender’s willful misconduct or gross
negligence in determining whether documents presented under a Letter of Credit
comply with the terms of such Letter of Credit.  In furtherance and not in limitation of the foregoing, the
Issuing Lender may accept documents that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary.


 


(g)           Cash Collateral Account.


 


(i)            If the Borrower is required to
deposit funds in the Cash Collateral Account pursuant to Sections 2.05(b),
7.02(b), or 7.03(b), then the Borrower and the Issuing Lender shall establish
the Cash Collateral Account and the Borrower shall execute any documents and
agreements, including the Issuing Lender’s standard form assignment of deposit
accounts, that the Issuing Lender requests in connection therewith to establish
the Cash Collateral Account and grant the Issuing Lender a first priority
security interest in such account and the funds therein.  The Borrower hereby pledges to the Issuing
Lender and grants the Issuing Lender a security interest in the Cash Collateral
Account, whenever established, all funds held in the Cash Collateral Account
from time to time, and all proceeds thereof as security for the payment of the
Obligations.


 


(ii)           So long as no Event of Default
Exists, (A) the Issuing Lender may apply the funds held in the Cash Collateral
Account only to the reimbursement of any Letter of Credit Obligations, and (B)
the Issuing Lender shall release to the Borrower at the Borrower’s written
request any funds held in the Cash Collateral Account in an amount up to but
not exceeding the excess, if any (immediately prior to the release of any such
funds), of the total amount of funds held in the Cash Collateral Account over
the Letter of Credit Exposure.  During
the existence of


 


30

















 


any Event of Default, the
Issuing Lender may apply any funds held in the Cash Collateral Account to the
Obligations in accordance with Section 7.06.


 


(iii)          The Issuing Lender shall exercise
reasonable care in the custody and preservation of any funds held in the Cash
Collateral Account and shall be deemed to have exercised such care if such
funds are accorded treatment substantially equivalent to that which the Issuing
Lender accords its own property, it being understood that the Issuing Lender shall
not have any responsibility for taking any necessary steps to preserve rights
against any parties with respect to any such funds.


 


Section 2.08       Fees.


 


(a)           Commitment Fees.  The Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee at a per
annum rate equal to the Applicable Margin for commitment fees on the average
daily Unused Commitment Amount of such Lender, from the date of this Agreement
until the Commitment Termination Date. 
The commitment fees shall be due and payable quarterly in arrears on the
last day of each March, June, September, and December commencing on March 31,
2003 and continuing thereafter through and including the Commitment Termination
Date.


 


(b)           Letter of Credit Fees.  The Borrower agrees to pay (i) to the
Administrative Agent for the pro rata benefit of the Lenders a per annum letter
of credit fee for each Financial Letter of Credit issued hereunder in an amount
equal to the Applicable Margin for Eurodollar Rate Advances on the aggregate
amount available for drawing from time to time under such Letter of Credit,
(ii) to the Administrative Agent for the pro rata benefit of the Lenders a per
annum letter of credit fee for each Performance Letter of Credit issued
hereunder in an amount equal to 50% of the Applicable Margin for Eurodollar
Rate Advances on the aggregate amount available for drawing from time to
time under such Letter of Credit.  Each
such fee will be calculated based on the face amount of all Letters of Credit
outstanding on each day at the above applicable rate and will be payable
quarterly in arrears.  In addition, the
Borrower agrees to pay to the Issuing Lender, (i) a fronting fee for each
Letter of Credit equal to 0.125% of the face amount of such Letter of Credit
and (ii) such other usual and customary fees associated with any transfers,
amendments, drawings, negotiations or reissuances of any Letters of Credit.


 


(c)           Other Fees.  The Borrower agrees to pay to the Lead
Arranger, the Administrative Agent and the Documentation Agent the fees
described in the Administrative Agent’s 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)           Base Rate Advances.  If such Advance is a Base Rate Advance, a
rate per annum equal at all times to the Adjusted Base 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 calendar quarter and on the date
such Base Rate Advance shall be paid in full, provided that upon the
occurrence and continuance of an Event of Default, such Advances shall bear
interest from the date on which such Event of Default occurred until such Event
of Default has been cured or


 


31

















 


 waived, payable on demand, at a rate per
annum equal at all times to the Adjusted Base Rate in effect from time to time plus
the Applicable Margin plus 2.00%, provided that the rate charged
pursuant to this Section 2.09(a) shall never exceed the Maximum Rate.


 


(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 six-month Interest Periods, on the
day which occurs during such Interest Period three months from the first day of
such Interest Period, provided that upon the occurrence and continuance
of an Event of Default, such Advance shall bear interest from the date on which
such Event of Default occurred until such Event of Default has been cured or
waived, payable on demand, at a rate per annum equal at all times to the rate
required to be paid on such Advance immediately prior to the occurrence of such
Event of Default plus 2.00%, provided  further, that any
amount of principal, interest, fees or any other amount which is not paid when
due (whether at stated maturity, by acceleration, or otherwise) shall bear
interest from the date on which such amount is due until such amount is paid in
full, payable on demand, at a rate per annum equal at all times to the Adjusted
Base Rate in effect from time to time plus the Applicable Margin plus
2.00%, provided that the rate charged pursuant to this Section 2.09(b) shall
never exceed the Maximum Rate.


 


(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 made hereunder are
repaid in full, the Lost Interest has not been fully recaptured by such Lender
pursuant to the preceding subsection (i), then, to the


 


32

















 


extent permitted by law, for
the loans made hereunder by such Lender the interest rates charged under this
Section 2.09 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.


 


(iii)          Notwithstanding the foregoing or any other term in this
Agreement and the Loan Documents to the contrary, it is the intention of each
Lender and the Borrower to conform strictly to any applicable usury laws.  Accordingly, if any Lender contracts for,
charges, or receives any consideration which constitutes interest in excess of
the maximum rate, then any such excess shall be canceled automatically and, if
previously paid, shall at such Lender’s option be applied to the outstanding
amount of the Advances made hereunder by such Lender or be refunded to the
Borrower.


 


Section 2.10       Payments
and Computations.


 


(a)           Payment Procedures.  The Borrower shall make each payment under
this Agreement and under the Notes not later than 12:00 p.m. (New York time) on
the day when due in Dollars to the Administrative Agent at the location
referred to in the Notes (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, the
Issuing Lender, or a specific Lender pursuant to Section 2.08(b), 2.08(c),
2.09(c), 2.12, 2.13, 2.14, 10.05, or 11.07, but after taking into account payments
effected pursuant to Section 10.04) 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 or the Issuing 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
Base 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


 


33

















 


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 next preceding Business Day.


 


(d)           Administrative Agent Reliance.  Unless the Administrative Agent shall have
received written notice from the Borrower prior to the date on which any
payment is due to the Lenders that the Borrower shall not make such payment in
full, the Administrative Agent may assume that the Borrower has made such
payment in full to the Administrative Agent on such date and the Administrative
Agent may, in reliance upon such assumption, cause to be distributed to each
Lender on such date an amount equal to the amount then due such Lender.  If and to the extent the Borrower shall not
have so made such payment in full to the Administrative Agent, each Lender
shall repay to the Administrative Agent forthwith on demand such amount
distributed to such Lender, together with interest, for each day from the date
such amount is distributed to such Lender until the date such Lender repays such
amount to the Administrative Agent, at the Federal Funds Rate for such day.


 


Section 2.11       Sharing
of Payments, Etc.  If any Lender
shall obtain any payment (whether voluntary, involuntary, through the exercise
of any right of set-off, or otherwise) on account of the Advances or Letter of
Credit Obligations made by it in excess of its Pro Rata Share of payments on
account of the Advances or Letter of Credit Obligations obtained by all the
Lenders, such Lender shall notify the Administrative Agent and forthwith
purchase from the other Lenders such participations in the Advances made by
them or Letter of Credit Obligations held by them as shall be necessary to
cause such purchasing Lender to share the excess payment ratably with each of
them; provided, however, that if all or any portion of such excess
payment is thereafter recovered from such purchasing Lender, such purchase from
each Lender shall be rescinded and such Lender shall repay to the purchasing
Lender the purchase price to the extent of such Lender’s ratable share
(according to the proportion of (a) the amount of the participation sold by
such Lender to the purchasing Lender as a result of such excess payment to (b)
the total amount of such excess payment) of such recovery, together with an
amount equal to such Lender’s ratable share (according to the proportion of (i)
the amount of such Lender’s required repayment to the purchasing Lender to (ii)
the total amount of all such required repayments to the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in
respect of the total amount so recovered. 
The Borrower agrees that any Lender so purchasing a participation from
another Lender pursuant to this Section 2.11 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation.


 


Section 2.12       Breakage
Costs.  If (a) any default by the
Borrower in making any borrowing of, conversion into or continuation of any
Eurodollar Rate Advance after the Borrower has given a notice requesting the
same in accordance with the provisions of this Agreement, (b) any payment of
any Eurodollar Rate Advance is made prior to 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 Notes pursuant to Article VII, or
otherwise, or (c) any default by the Borrower in making any prepayment of any
Eurodollar Rate Advance after the Borrower has given notice thereof in
accordance with the provisions of this Agreement, 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


 


34

















 


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, without limitation, any loss, cost, or expense incurred
by reason of the liquidation or reemployment of deposits or other funds
acquired by such Lender to fund or maintain such Advance.


 


Section 2.13       Increased
Costs.


 


(a)           Eurodollar Rate Advances.  If, due to either (i) the introduction of or
any change (other than any change by way of imposition or increase of reserve
requirements included in the Eurodollar Rate Reserve Percentage) in or in the
interpretation of any law or regulation or (ii) the compliance with any
guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the
cost to any Lender of agreeing to make or making, funding, or maintaining
Eurodollar Rate Advances, then the Borrower shall from time to time, upon
demand by such Lender (with a copy of such demand to the Administrative Agent),
immediately pay to the Administrative Agent for the account of such Lender
additional amounts sufficient to compensate such Lender for such increased
cost.  A certificate as to the amount of
such increased cost and detailing the calculation of such cost submitted to the
Borrower and the Administrative Agent by such Lender shall be conclusive and
binding for all purposes, absent manifest error.


 


(b)           Capital Adequacy.  If any Lender or the Issuing Lender
determines in good faith that compliance with any law or regulation or any
guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law) affects or would affect the amount of
capital required or expected to be maintained by such Lender or the Issuing
Lender or any corporation controlling such Lender or the Issuing Lender and
that the amount of such capital is increased by or based upon the existence of
such Lender’s commitment to lend or the Issuing Lender’s commitment to issue
the Letters of Credit and other commitments of this type, then, upon 30 days’
prior written notice by such Lender or the Issuing Lender (with a copy of any
such demand to the Administrative Agent), the Borrower shall immediately pay to
the Administrative Agent for the account of such Lender or to the Issuing
Lender, as the case may be, from time to time as specified by such Lender or
the Issuing Lender, additional amounts sufficient to compensate such Lender or
the Issuing Lender for the reduced rate of return on that capital of such
Lender or the Issuing Lender (but without duplication of amounts, if any, paid
by the Borrower pursuant to Section 2.13(a) above), in light of such
circumstances, (i) with respect to such Lender, to the extent that such Lender
reasonably determines such increase in capital to be allocable to the existence
of such Lender’s commitment to lend under this Agreement and (ii) with respect
to the Issuing Lender, to the extent that the Issuing Lender reasonably
determines such increase in capital to be allocable to the issuance or
maintenance of the Letters of Credit.  A
certificate as to such amounts and detailing the calculation of such amounts
submitted to the Borrower by such Lender or the Issuing Lender shall be
conclusive and binding for all purposes, absent manifest error.


 


(c)           Letters of Credit.  If any change in any law or regulation or in
the interpretation thereof by any court or administrative or Governmental
Authority charged with the administration thereof shall either (i) impose,
modify, or deem applicable any reserve, special deposit, or similar requirement
against letters of credit issued by, or assets held by, or deposits in 


 


35

















 


or for the account of, the
Issuing Lender or (ii) impose on the Issuing Lender any other condition
regarding the provisions of this Agreement relating to the Letters of Credit or
any Letter of Credit Obligations, and the result of any event referred to in
the preceding clause (i) or (ii) shall be to increase the cost to the Issuing
Lender of issuing or maintaining any Letter of Credit (which increase in cost
shall be determined by the Issuing Lender’s reasonable allocation of the
aggregate of such cost increases resulting from such event), then, upon demand
by the Issuing Lender, the Borrower shall pay to the Issuing Lender, from time
to time as specified by the Issuing Lender, additional amounts which shall be
sufficient to compensate the Issuing Lender for such increased cost.  A certificate as to such increased cost
incurred by the Issuing Lender, as a result of any event mentioned in clause
(i) or (ii) above, and detailing the calculation of such increased costs
submitted by the Issuing Lender to the Borrower, shall be conclusive and
binding for all purposes, absent manifest error.


 


Section 2.14       Taxes.


 


(a)           No Deduction for Certain Taxes.  Any and all payments by the Borrower shall
be made, in accordance with Section 2.10, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding,
in the case of each Lender, the Issuing Lender, and the Administrative Agent,
taxes imposed on its net income, and franchise taxes imposed on it, by the
jurisdiction under the laws of which such Lender, the Issuing Lender, or the
Administrative Agent (as the case may be) is organized or any political
subdivision of the jurisdiction (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as “Taxes”) and, in the case of each Lender and the Issuing Lender,
Taxes by the jurisdiction of such Lender’s Applicable Lending Office or any
political subdivision of such jurisdiction. 
If the Borrower shall be required by law to deduct any Taxes from or in
respect of any sum payable to any Lender, the Issuing Lender, or the
Administrative Agent, (i) the sum payable shall be increased as may be
necessary so that, after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.14), such Lender,
the Issuing Lender, or the Administrative Agent (as the case may be) receives
an amount equal to the sum it would have received had no such deductions been
made; provided, however, that if the Borrower’s obligation to deduct or
withhold Taxes is caused solely by such Lender’s, the Issuing Lender’s, or the
Administrative Agent’s failure to provide the forms described in paragraph (d)
of this Section 2.14 and such Lender, the Issuing Lender, or the Administrative
Agent could have provided such forms, no such increase shall be required; (ii)
the Borrower shall make such deductions; and (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.


 


(b)           Other Taxes.  In addition, the Borrower agrees to pay any
present or future stamp or documentary taxes or any other excise or property
taxes, charges or similar levies which arise from any payment made or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement, the Notes, or the other Loan Documents (hereinafter referred to as “Other
Taxes”).


 


(c)           Indemnification.  THE
BORROWER INDEMNIFIES EACH LENDER, THE ISSUING LENDER, AND THE ADMINISTRATIVE
AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING, WITHOUT
LIMITATION, ANY TAXES OR OTHER TAXES IMPOSED BY ANY


 


36

















 


jurisdiction
on amounts payable under this Section 2.14) paid by such Lender, the Issuing
Lender, or the Administrative Agent (as the case may be) and any liability
(including interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted
unless the payment of such Taxes or Other Taxes were not correctly or legal
asserted and such Lender’s payment of such Taxes or Other Taxes was the result
of its gross negligence or wilful misconduct. 
Each payment required to be made by the Borrower in respect of this
indemnification shall be made to the Administrative Agent for the benefit of
any party claiming such indemnification within 30 days from the date the
Borrower receives written demand therefor from the Administrative Agent on
behalf of itself as Administrative Agent, the Issuing Lender, or any such
Lender.  If any Lender, the
Administrative Agent, or the Issuing Lender receives a refund in respect of any
Taxes paid by the Borrower under this paragraph (c), such Lender, the
Administrative Agent, or the Issuing Lender, as the case may be, shall promptly
pay to the Borrower the Borrower’s share of such refund.


 


(d)           Foreign Lender Withholding
Exemption.  Each Lender and Issuing
Lender that is not incorporated under the laws of the United States of America
or a state thereof agrees that upon the request of the Borrower it shall
deliver to the Borrower and the Administrative Agent (i) two duly completed
copies of United States Internal Revenue Service Form W8-ECI, W8-IMY or W8-BEN
or successor applicable form, as the case may be, certifying in each case that
such Lender is entitled to receive payments under this Agreement and the Notes
payable to it, without deduction or withholding of any United States federal
income taxes, (ii) if applicable, an Internal Revenue Service Form W-9 or
successor applicable form, as the case may be, to establish an exemption from
United States backup withholding tax, and (iii) any other governmental forms
which are necessary or required under an applicable tax treaty or otherwise by
law to reduce or eliminate any withholding tax, which have been reasonably
requested by the Borrower.  If an event
(including without limitation any change in treaty, law or regulation) has
occurred prior to the date on which any delivery required by the preceding
sentence would otherwise be required which renders all such forms inapplicable
or which would prevent any Lender from duly completing and delivering any such
form with respect to it and such Lender advises the Borrower and the
Administrative Agent that it is not capable of receiving payments without any
deduction or withholding of United States federal income tax, and in the case
of a Form W-9 establishing an exemption from United States backup
withholding tax, such Lender shall not be required to deliver such form.  The Borrower shall withhold tax at the rate
and in the manner required by the laws of the United States with respect to
payments made to a Lender failing to timely provide the requisite Internal
Revenue Service forms.  For any period
with respect to which a Lender or the Issuing Lender has failed to provide the
Borrower and the Administrative Agent with the appropriate form pursuant to
this Section 2.14(d) (unless such failure is due to a change in treaty or Legal
Requirement occurring subsequent to the date on which a form originally was
required to be provided), such Lender or the Issuing Lender, as applicable,
shall not be entitled to indemnification under Section 2.14(c) with respect to
Taxes imposed by the United States which taxes would not have been imposed but for
such failure to provide such forms; provided, however that should
a Lender, which is otherwise exempt from or subject to a reduced rate of
withholding tax becomes subject to Taxes because of its failure to


 


37

















 


deliver a form required
hereunder, the Borrower shall take such steps as such Lender shall reasonable
request to assist such Lender to recover such Taxes.

at the time such projections, estimates, and pro forma financial information
were furnished, but the Credit Parties do not represent and warrant that such
projections, estimates or pro forma information is (or will ultimately prove to
have been) accurate.

Section 4.07       Litigation.  There is no pending or, to the knowledge of
any Responsible Officer of any Credit Party, threatened action or proceeding
affecting any of the Credit Parties before any court, Governmental Authority or
arbitrator which (a) both (i) involves the possibility of any judgment or
liability against any Credit Party not fully covered by insurance (except for
normal deductibles) and (ii) could reasonably be expected to be cause a
Material Adverse Change or (b) 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 knowledge of any Responsible Officer of any Credit Party,
threatened action or proceeding instituted against any Credit Party which seeks
to adjudicate such Credit Party 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.


 


Section 4.08       Taxes.


 


(a)           Reports and Payments.  All Returns (as defined below in clause (c)
of this Section) required to be filed by or on behalf of any Credit Party 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
in all material respects; 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 where any obligation is
being contested in good faith and by appropriate proceedings and after adequate
reserves for such items have been made in accordance with GAAP.  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.


 


(b)           Taxes Definition.  “Taxes” in this Section 4.08 shall
mean all taxes, charges, fees, levies, or other assessments imposed by any
federal, state, local, or foreign taxing authority, including without
limitation, 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 with respect to any such assessment).


 


(c)           Returns Definition.  “Returns” in this Section 4.08 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.


 


Section 4.09       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


 


44

















 


with applicable provisions of
ERISA and the Code.  No “accumulated
funding deficiency” (as defined in Section 302 of ERISA) has occurred 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 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.  None of the Credit Parties or
any member of the Controlled Group has had a complete or partial withdrawal
from any Multiemployer Plan for which there is any withdrawal liability.  As of the most recent valuation date applicable
thereto, none of the Credit Parties or any member of the Controlled Group would
become subject to any liability under ERISA if any Credit Party or any member
of the Controlled Group 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, no Credit Party has reason to believe that the annual cost
during the term of this Agreement to any Credit Party or any other 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 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 4.10       Condition
of Property; Casualties.


 


(a)           Subject to the matters set forth in Schedule
4.10, each of the Borrower and its Subsidiaries has good and indefeasible
title to all of its Oil and Gas Properties evaluated in any Engineering Report,
free and clear of all Liens except for Permitted Liens.  Brigham Exploration has good and defensible
title to all of the Equity Interests in the General Partner and, directly and
indirectly, all of the ownership interests in the Limited Partners, except for
Permitted Liens.  Each of the General
Partner and the Limited Partners has good and defensible title to all of the
Equity Interests in the Borrower, except for Permitted Liens.


 


(b)           The quantum and nature of the
interest of the Borrower and its Subsidiaries in and to its Hydrocarbon
Interests as set forth in each Engineering Report includes the entire interest
of the Borrower and its Subsidiaries in such Hydrocarbon Interests as of the
date of such Engineering Report and are complete and accurate in all material
respects as of the date of such Engineering Report; and there are no “back-in”
or “reversionary” interests held by third parties which could materially reduce
the interest of the Borrower and its Subsidiaries in such Hydrocarbon Interests
except as taken into account in such Engineering Report.  The ownership of the Hydrocarbon Interests
held by the Borrower and its Subsidiaries shall not in any material respect
obligate any such Person to bear the costs and expenses relating to the
maintenance, development or operations of such Hydrocarbon Interests in an
amount in excess of the working interest of such Person in each such
Hydrocarbon Interest set forth in the most recent Engineering Report.


 


(c)           All leases and agreements comprising
the Borrower’s and its Subsidiaries’ Oil and Gas Properties necessary for the
conduct of business of the Borrower and its Subsidiaries 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


 


45

















 


under any such leases,
instruments or agreements which would affect in any material respect the
conduct of the business of the Borrower and its Subsidiaries.  Neither Borrower or any of its Subsidiaries
nor, to the knowledge of Borrower, any other party to any leases, instruments
or agreements comprising its Oil and Gas Properties evaluated in any Engineering
Report, has given or threatened to give notice of any default under or inquiry
into any possible default under, or action to alter, terminate, rescind or
procure a judicial reformation of, any such lease, instrument or
agreement.  Except as set forth on Schedule
4.10 or as otherwise disclosed in writing to the Administrative Agent,
neither the Borrower nor any of its Subsidiaries is subject to any obligation
to drill additional wells, finance the drilling of additional wells, or conduct
additional operations in order to earn or continue to own any Significant PUD
Location or any other proved developed producing reserves or proved developed
nonproducing reserves evaluated in any Engineering Report.


 


(d)           The Properties presently owned,
leased or licensed by the Borrower and its Subsidiaries, including, without
limitation, all leases, easements, rights of way, and contractual rights,
include all Properties necessary to permit the Borrower and its Subsidiaries to
conduct their business in all material respects in the same manner as its
business has been conducted prior to the Closing Date.


 


(e)           All of the Properties of the Borrower
and its Subsidiaries that are reasonably necessary for the operation of their
business are in good repair, working order and condition in all material
respects and are maintained in accordance with prudent business standards.  Since the date of the most recent financial
statements delivered pursuant to Section 5.06(a), neither the business nor the
Properties of the Credit Parties, 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.


 


(f)            Except as set forth on Schedule 4.10
or as otherwise disclosed in writing to the Administrative Agent:


 


(i)            In each case only with respect to
any of the Borrower’s and its Subsidiaries’ Oil and Gas Properties that have
been assigned a discounted present value equal to or in excess of $2,000,000 in
any Engineering Report, (A) all rentals, royalties, overriding royalties,
shut-in royalties and other payments due under or with respect to any such
Hydrocarbon Interests evaluated in any Engineering Report have been properly
and timely paid in the ordinary course of business and (B) all material
expenses payable under the terms of the contracts and agreements comprising
such Oil and Gas Properties (other than those described above in clause (A))
have been properly and timely paid in the ordinary course of business except in
each case (1) where such payments are being contested in good faith by
appropriate proceedings and for which adequate reserves complying with GAAP
have been made or (2) for payments the late payment of which could not
reasonably be expected to cause a termination or forfeiture of any of the
Borrower’s or its Subsidiaries’ rights under any such leases, instruments or
agreements comprising any such Oil and Gas Properties or otherwise,
individually or in the aggregate, cause a Material Adverse Change;


 


46

















 


(ii)           All of the proceeds from the sale of
Hydrocarbons produced from the Borrower’s and its Subsidiaries’ Hydrocarbon
Interests are being properly and timely paid to the Borrower without suspense,
other than any such proceeds the late payment or non-payment of which could not
reasonably be expected to cause a Material Adverse Change or materially
adversely affect the value of the Collateral taken as a whole; and


 


(iii)          No material amount of proceeds that
has been received by any Credit Party from the sale of Hydrocarbons produced
from the Oil and Gas Properties evaluated in any Engineering Report is subject
to any claim for any refund or refund obligation, except as permitted under
Section 4.14 or Section 6.13.


 


Section 4.11       Security
Instruments.


 


(a)           The provisions of each of the Pledge
Agreements delivered to the Administrative Agent are effective to create in
favor of the Administrative Agent, for the ratable benefit of the Lenders, a
legal, valid and enforceable security interest in the Pledged Collateral (as
defined therein) and proceeds thereof and when (i) certificates, if any,
representing or constituting the Pledged Collateral are delivered to the
Administrative Agent, the Pledge Agreement shall constitute a first priority
Acceptable Security Interest in, all right, title and interest of the pledgor
party thereto in such Pledged Collateral and the proceeds thereof, subject to
Permitted Liens or and (ii) upon the filing of UCC-1 Financing Statements with
the secretary of state of each jurisdiction of formation for each of the
grantors party thereto, the Pledge Agreements shall constitute a first priority
Acceptable Security Interest in, all right, title and interest of the
applicable Credit Party in such Pledged Collateral and the proceeds thereof,
subject to Permitted Liens.


 


(b)           On the Closing Date, the Equity Interests
listed on Schedule I to each of the Pledge Agreements will constitute
all the issued and outstanding Equity Interests in the Borrower, the General
Partner, the Limited Partners, and the direct and indirect Subsidiaries of the
Borrower; all such Equity Interests have been duly and validly issued and are
fully paid and nonassessable; and the relevant pledgor of said shares is the
record and beneficial owner of said shares.


 


(c)           The provisions of the Mortgages will
be effective to grant to the Administrative Agent, for the ratable benefit of
the Lenders, legal, valid and enforceable mortgage liens on all of the right,
title and interest of the Borrower and its Subsidiaries in the mortgaged
property described therein.  Once such
Mortgages have been recorded in the appropriate recording office, the Mortgages
will constitute perfected first liens on, and security interest in, such
mortgaged property, subject to Permitted Liens.


 


(d)           The provisions of each of the
Security Agreements delivered to the Administrative Agent are effective to
create in favor of the Administrative Agent, for the ratable benefit of the
Lenders, a legal, valid and enforceable security interest in the collateral
described therein and proceeds thereof and, upon the filing of UCC-1 Financing
Statements with the secretary of state of each jurisdiction of formation for
each of the grantors party thereto, the Security Agreement shall constitute a
first priority Acceptable Security Interest in, all right, title


 


47

















 


and interest of the applicable
Credit Party in such collateral and the proceeds thereof, subject to Permitted
Liens.


 


(e)           Once the Deposit Control Agreements
have been executed, the provisions of each of the Deposit Control Agreements will
be effective to create in favor of the Administrative Agent, for the ratable
benefit of the Lenders, a legal, valid and enforceable security interest in the
collateral described therein and proceeds thereof and shall constitute a first
priority Acceptable Security Interest in, all right, title and interest of the
applicable Credit Party in such collateral and the proceeds thereof, subject to
Permitted Liens.


 


(f)            On the Closing Date and except with
respect to the Deposit Control Agreements until such Deposit Control Agreements
have been executed, 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 (or are the subject
of arrangements, satisfactory to the Administrative Agent, to be made, obtained
or taken on or promptly after the Closing Date).  No other filings or recordings are required in order to perfect
the security interests created under any Security Instruments.


 


Section 4.12       No
Burdensome Restrictions; No Defaults.


 


(a)           Neither the Borrower nor any of its
Subsidiaries 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 law or governmental regulation that
could reasonably be expected to cause a Material Adverse Change.  Neither the Borrower nor any of its
Subsidiaries is in default nor has any event or circumstance occurred which,
but the expiration of any grace period or the giving of notice, or both, would
constitute a default under (i) the Subordinated Credit Agreement or (ii) any
other material contract, agreement, lease, or other instrument to which such
Credit Party is a party which default could reasonably be expected to cause a
Material Adverse Change.  None of the
Credit Parties has received any notice of default under any material contract,
agreement, lease, or other instrument to which such Credit Party is a party.


 


(b)           No Default has occurred and is
continuing.


 


Section 4.13       Environmental
Condition.  Other than exceptions to
any of the following that would not reasonably be expected to cause a Material
Adverse Change or materially adversely affect the value of the Collateral taken
as a whole:


 


(a)           Permits, Etc.  With respect to its Oil and Gas Properties
for which such Credit Party is the operator and with respect to its Oil and Gas
Properties that are operated by operators other than the Borrower or a
Subsidiary, to the best of its knowledge, in all material respects, each of the
Credit Parties (i) has obtained all Environmental Permits necessary for the
ownership and operation of any and all of their respective Properties and the
conduct of their respective businesses; (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 and other Legal Requirements;
(iii) have not received notice of any violation or alleged violation of any


 


48

















 


Environmental Law or any such
Permit; and (iv) are not subject to any actual or contingent Environmental
Claim with respect to such Properties.


 


(b)           Certain Liabilities.  None of the present or, to the best
knowledge of any Credit Party, previously owned or operated Property of any of
the Credit Parties, 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 other than a Permitted 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 its Subsidiaries,
wherever located; or (iii) has been the site of any Release of Hazardous
Substances or Hazardous Wastes from present or past operations that 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.


 


(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 its Subsidiaries or any of their
former Subsidiaries on any of their presently or formerly owned or operated
Property and (ii) there is no present and, to the Borrower’s knowledge, future
liability, if any, of the Borrower and its Subsidiaries which could reasonably
be expected to arise in connection with requirements under Environmental Laws.


 


Section 4.14       Gas
Contracts.  Except as set forth in
the most recent Engineering Report or in Schedule 4.14, on a net basis
there are no material gas imbalances, material take-or-pay or other prepayments
with respect to the Oil and Gas Properties of the Borrower and its Subsidiaries
(or, in the case of Oil and Gas Properties operated by operators other than the
Borrower or its Subsidiaries, to the Borrower’s knowledge after reasonable
investigation) that would require the Borrower and its Subsidiaries to deliver
2.5% or more of the aggregate calendar quarter production from the Borrower’s
and its Subsidiaries’ Hydrocarbons produced on a calendar quarter basis from
their Hydrocarbon Interests at some future time without then or thereafter
receiving full payment therefor.


 


Section 4.15       Compliance
with Laws.  Except for any failure
to comply with any of the foregoing which would not reasonably be expected to
cause a Material Adverse Change, each of the Credit Parties has (a) complied
with all applicable Legal Requirements of any Governmental Authority having
jurisdiction over the conduct of their respective businesses or the ownership
of their respective Property and (b) obtained all Permits that are necessary
for the ownership of any of its Properties or the conduct of their business.  Other than immaterial exceptions to any of
the following: (i) the prices being received by the Borrower and its
Subsidiaries for the production of Hydrocarbons do not violate any material
provision of any contract or agreement comprising the Oil and Gas Properties of
the Borrower and its Subsidiaries or any Legal Requirement, (ii)   where applicable, all of the wells located
on the Borrower’s and its Subsidiaries’ Hydrocarbon Interests and production of
Hydrocarbons therefrom have been properly classified under appropriate
governmental regulations, (iii) all necessary regulatory filings have been

and (iv) all production and sales of the Borrower’s and its Subsidiaries’
Hydrocarbons produced or sold from the Borrower’s and its Subsidiaries’
Hydrocarbon Interests have been made in accordance with any applicable
allowables (plus permitted tolerances) imposed by any Governmental Authorities.


 


Section 4.16       Hedging
Agreements.  Schedule 4.16
sets forth, as of the Closing Date, a true and complete list of all Interest
Hedge Agreements and Hydrocarbon Hedge Agreements of the Borrower and each of
its Subsidiaries, setting forth the type, term, effective date, termination
date and notional amounts or volumes, and the counterparty to each such
agreement.


 


Section 4.17       Material
Agreements.  Schedule 4.17
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

4.16) providing for, evidencing, securing or otherwise relating to any
material Debt of the Borrower or any of its Subsidiaries, and all obligations
of the Borrower or any of its Subsidiaries to issuers of surety or appeal bonds
(other than operator’s bonds, plugging and abandonment bonds, and similar
surety obligations obtained in the ordinary course of business) issued for the
account of the Borrower or any of its Subsidiaries, 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.


 


Section 4.18       Organizational
Documents.  The Partnership

5.10.  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 4.22       Investment

ARTICLE V



AFFIRMATIVE COVENANTS


 


So long as any Note or any amount under any
Loan Document shall remain unpaid, any Letter of Credit shall remain
outstanding, or any Lender shall have any Commitment hereunder, each of the
Credit Parties agrees 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; 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 use commercially reasonable efforts to obtain, and shall cause
each of its Subsidiaries to use commercially reasonable efforts to obtain, as
soon as practicable, all consents or approvals required from 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, maintain with financially sound and reputable
insurance companies insurance of such types, in such amounts and against such
risks as is customary to be maintained by companies engaged in the same or a
similar business in the same general area; and furnish to the Administrative
Agent, upon written request, full information as to the insurance carried.  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. 
All 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.  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. 
In addition, 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.  All such policies shall contain a provision
that notwithstanding


 


51

















 


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 10 days’ prior written notice to the Administrative
Agent in the event of the Borrower’s failure to pay any premiums and in all other
cases, 30 days’ prior written notice to the Administrative Agent.  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 of the Borrower, the Borrower shall deliver such proceeds to the
Administrative Agent immediately upon receipt.


 


Section 5.03       Preservation
of Corporate Existence, Etc.  Each
of the Credit Parties shall preserve and maintain its corporate, limited
partnership or limited liability company, as applicable, existence, and all of
its material rights, franchises, and privileges in the jurisdiction of its
formation, and 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 to the extent the
failure to qualify could reasonably be expected to cause a Material Adverse
Change.


 


Section 5.04       Payment
of Taxes, Etc.  The Borrower shall,
and shall 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 prior to the
date on which penalties attach thereto and (b) all lawful claims that are
material in amount which, if unpaid, could 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       Inspection;
Books and Records.  Upon reasonable
notice, each Credit Party shall permit the Administrative Agent and any Lender
or any of their respective agents or representatives thereof, during normal
business hours, 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, such Credit Party, and (b) discuss the affairs,
finances and accounts of such Credit Party with any of their respective
officers or directors, all to the extent reasonably requested by the
Administrative Agent or such Lender, as the case may be.  Each Credit Party shall keep proper books of
records and account in which full, true and correct entries in conformity with
GAAP and all Legal Requirements shall be made of all dealings and transactions
in relation to its business and activities.


 


Section 5.06       Reporting
Requirements.  The Borrower shall
furnish, or shall cause the applicable Credit Party to furnish, to the
Administrative Agent and each Lender:


 


(a)           Annual Financials of Brigham
Exploration.  As soon as available,
but in any event within 90 days after the end of each fiscal year of Brigham
Exploration or sooner if required by the SEC, the audited consolidated
statements of income, stockholders’ equity, changes in financial position and
cash flow of Brigham Exploration and its consolidated Subsidiaries for such
fiscal year, and the related consolidated and unaudited consolidating balance
sheets of


 


52

















 


Brigham Exploration and its
consolidated Subsidiaries as at the end of such fiscal year, and setting forth
in each case in comparative form the corresponding figures for the preceding
fiscal year, together with a certification by its Chief Executive Officer and
its Chief Financial Officer in accordance with the Sarbanes-Oxley Act of 2002
and accompanied by the related opinion of independent public accountants of
recognized national standing reasonably acceptable to the Administrative Agent
which opinion shall state that such financial statements fairly present the
consolidated financial position and results of operations of Brigham
Exploration and its consolidated Subsidiaries as at the end of, and for, such
fiscal year and that such financial statements have been prepared in accordance
with GAAP except for such changes in such principles with which the independent
public accountants shall have concurred and such opinion shall not contain a
“going concern” or like qualification or exception;


 


(b)           Quarterly Financials of Brigham

ARTICLE
VIII



THE GUARANTY


 


Section 8.01       Liabilities
Guaranteed. Each Guarantor hereby, joint and severally, irrevocably and
unconditionally guarantees the prompt payment at maturity of the Obligations.


 


Section 8.02       Nature
of Guaranty. This guaranty is an absolute, irrevocable, completed and
continuing guaranty of payment and not a guaranty of collection, and no notice
of the Obligations or any extension of credit already or hereafter contracted
by or extended to the Borrower need be given to any Guarantor. This guaranty
may not be revoked by any Guarantor and shall continue to be effective with
respect to the Obligations arising or created after any attempted revocation by
such Guarantor and shall remain in full force and effect until the Obligations
are paid in full and the Commitments are terminated, notwithstanding that from
time to time prior thereto no Obligations may be outstanding. The Borrower and
the Lenders may modify, alter, rearrange, extend for any period and/or renew
from time to time, the Obligations, and the Lenders may waive any Default or
Events of Default without notice to any Guarantor and in such event each
Guarantor will remain fully bound hereunder on the Obligations. This guaranty
shall continue to be effective or be reinstated, as the case may be, if at any
time any payment of the Obligations is rescinded or must otherwise be returned
by any of the Lenders upon the insolvency, bankruptcy or reorganization of the
Borrower or otherwise, all as though such payment had not been made. This
guaranty may be enforced by the Administrative Agent and any subsequent holder
of any of the Obligations and shall not be discharged by the assignment or
negotiation of all or part of the Obligations. Each Guarantor hereby expressly
waives presentment, demand, notice of non-payment, protest and notice of
protest and dishonor, notice of Default or Event of Default, and also notice of
acceptance of this guaranty, acceptance on the part of the Lenders being
conclusively presumed by the Lenders’ request for this guaranty and the
Guarantors’ being party to this Agreement.


 


Section 8.03       Agent’s
Rights. Each Guarantor authorizes the Administrative Agent, without notice
or demand and without affecting any Guarantor’s liability hereunder, to take
and hold security for the payment of its obligations under this Article VIII
and/or the Obligations, and exchange, enforce, waive and release any such
security; and to apply such security and direct the order or manner of sale
thereof as the Administrative Agent in its discretion may determine, and to
obtain a guaranty of the Obligations from any one or more Persons and at any
time or times to enforce, waive, rearrange, modify, limit or release any of
such other Persons from their obligations under such guaranties.


 


Section 8.04       Guarantor’s
Waivers.


 


(a)           General. Each Guarantor waives
any right to require any of the Lenders to (i) proceed against the Borrower or
any other person liable on the Obligations, (ii) enforce any of their rights
against any other guarantor of the Obligations, (iii) proceed or enforce any of
their


 


69

















 


rights against or exhaust any
security given to secure the Obligations, (iv) have the Borrower joined with
any Guarantor in any suit arising out of this Article VIII and/or the
Obligations, or (v) pursue any other remedy in the Lenders’ powers whatsoever.
The Lenders shall not be required to mitigate damages or take any action to
reduce, collect or enforce the Obligations. Guarantor waives any defense
arising by reason of any disability, lack of corporate authority or power, or
other defense of the Borrower or any other guarantor of the Obligations, and
shall remain liable hereon regardless of whether the Borrower or any other
guarantor be found not liable thereon for any reason. Whether and when to
exercise any of the remedies of the Lenders under any of the Loan Documents
shall be in the sole and absolute discretion of the Administrative Agent, and
no delay by the Administrative Agent in enforcing any remedy, including delay
in conducting a foreclosure sale, shall be a defense to any Guarantor’s
liability under this Article VIII.


 


(b)           Subrogation. Until the
Obligations have been paid in full, each Guarantor waives all rights of
subrogation or reimbursement against the Borrower, whether arising by contract
or operation of law (including, without limitation, any such right arising
under any federal or state bankruptcy or insolvency laws) and waives any right
to enforce any remedy which the Lenders now have or may hereafter have against
the Borrower, and waives any benefit or any right to participate in any security
now or hereafter held by the Administrative Agent or any Lender.


 


Section 8.05       Maturity
of Obligations, Payment. Each Guarantor agrees that if the maturity of any
of the Obligations is accelerated by bankruptcy or otherwise, such maturity
shall also be deemed accelerated for the purpose of this Article VIII without
demand or notice to any Guarantor. Each Guarantor will, forthwith upon notice
from the Administrative Agent, jointly and severally pay to the Administrative
Agent the amount due and unpaid by the Borrower and guaranteed hereby. The
failure of the Administrative Agent to give this notice shall not in any way
release any Guarantor hereunder.


 


Section 8.06       Agent’s
Expenses. If any Guarantor fails to pay the Obligations after notice from
the Administrative Agent of the Borrower’s failure to pay any Obligations at
maturity, and if the Administrative Agent obtains the services of an attorney
for collection of amounts owing by any Guarantor hereunder, or obtaining advice
of counsel in respect of any of their rights under this Article VIII, or if
suit is filed to enforce this Article VIII, or if proceedings are had in any
bankruptcy, probate, receivership or other judicial proceedings for the
establishment or collection of any amount owing by any Guarantor hereunder, or
if any amount owing by any Guarantor hereunder is collected through such
proceedings, each Guarantor jointly and severally agrees to pay to the
Administrative Agent the Administrative Agent’s reasonable attorneys’ fees.


 


Section 8.07       Liability.  It is expressly agreed that the liability of
each Guarantor for the payment of the Obligations guaranteed hereby shall be
primary and not secondary.


 


Section 8.08       Events
and Circumstances Not Reducing or Discharging any Guarantor’s Obligations.
Each Guarantor hereby consents and agrees to each of the following to the
fullest extent permitted by law, and agrees that each Guarantor’s obligations
under this Article VIII shall not be released, diminished, impaired, reduced or
adversely affected by any of the


 


70

might otherwise have as a result of or in connection with any of the following:


 


(a)           Modifications, etc. Any
renewal, extension, modification, increase, decrease, alteration or

Person, pertaining to the Obligations;

adjustment, indulgence, forbearance or compromise that might be granted or
given by any of the Lenders to the Borrower or any Guarantor or any Person
liable on the Obligations;


 


(c)           Condition of the Borrower or any
Guarantor. The insolvency, bankruptcy arrangement, adjustment, composition,

part of the Obligations; or any dissolution of the Borrower or any Guarantor,

any Guarantor, or any changes in the shareholders, partners, or members of the

Guarantor;

that the Obligations, or any part thereof, exceed the amount permitted by law,

(e)           Release of Obligors. Any full
or partial release of the liability of the Borrower on the Obligations or any
part thereof, of any co-guarantors, or any other Person now or hereafter
liable, whether directly or indirectly, jointly, severally, or jointly and
severally, to pay, perform, guarantee or assure the payment of the Obligations
or any part thereof, it being recognized, acknowledged and agreed by any Guarantor
that such Guarantor may be required to pay the Obligations in full without
assistance or support of any other Person, and no Guarantor has been induced to
enter into this Article VIII on the basis of a contemplation, belief,
understanding or agreement that other parties other than the Borrower will be
liable to perform the Obligations, or the Lenders will look to other parties to
perform the Obligations.


 


(f)            Other Security. The taking or
accepting of any other security, collateral or guaranty, or other assurance of
payment, for all or any part of the Obligations;


 


71

















 


(g)           Release of Collateral etc. Any
release, surrender, exchange, subordination, deterioration, waste, loss or
impairment (including without limitation negligent, willful, unreasonable or
unjustifiable impairment) of any collateral, property or security, at any time
existing in connection with, or assuring or securing payment of, all or any
part of the Obligations;


 


(h)           Care and Diligence. The
failure of the Lenders or any other Person to exercise diligence or reasonable
care in the preservation, protection, enforcement, sale or other handling or
treatment of all or any part of such collateral, property or security;


 


(i)            Status of Liens. The fact
that any collateral, security, security interest or lien contemplated or
intended to be given, created or granted as security for the repayment of the
Obligations shall not be properly perfected or created, or shall prove to be
unenforceable or subordinate to any other security interest or lien, it being
recognized and agreed by each Guarantor that no Guarantor is entering into this
Article VIII in reliance on, or in contemplation of the benefits of, the
validity, enforceability, collectibility or value of any of the collateral for
the Obligations;


 


(j)            Payments Rescinded. Any
payment by the Borrower to the Lenders is held to constitute a preference under
the bankruptcy laws, or for any reason the Lenders are required to refund such
payment or pay such amount to the Borrower or someone else; or


 


(k)           Other Actions Taken or Omitted.  Any other action taken or omitted to be
taken with respect to this Agreement, the Obligations, or the security and
collateral therefor, whether or not such action or omission prejudices any
Guarantor or increases the likelihood that any Guarantor will be required to
pay the Obligations pursuant to the terms hereof, it being the unambiguous and
unequivocal intention of each Guarantor that each Guarantor shall be obligated
to joint and severally pay the Obligations when due, notwithstanding any
occurrence, circumstance, event, action, or omission whatsoever, whether
contemplated or uncontemplated, and whether or not otherwise or particularly
described herein, except for the full and final payment and satisfaction of the
Obligations.


 


Section 8.09       Subordination
of All Guarantor Claims. As used herein, the term “Guarantor Claims” shall
mean all debts and liabilities of the Borrower or any Subsidiary of the
Borrower to any Guarantor, whether such debts and liabilities now exist or are
hereafter incurred or arise, or whether the obligation of the Borrower or such
Subsidiary thereon be direct, contingent, primary, secondary, several, joint
and several, or otherwise, and irrespective of whether such debts or
liabilities be evidenced by note, contract, open account, or otherwise, and
irrespective of the person or persons in whose favor such debts or liabilities
may, at their inception, have been, or may hereafter be created, or the manner in
which they have been or may hereafter be acquired by any Guarantor. The
Guarantor Claims shall include without limitation all rights and claims of any
Guarantor against the Borrower or any Subsidiary of the Borrower arising as a
result of subrogation or otherwise as a result of such Guarantor’s payment of
all or a portion of the Obligations. Until the Obligations shall be paid and
satisfied in full and each Guarantor shall have performed all of its
obligations hereunder, no Guarantor shall receive or collect, directly or
indirectly, from the Borrower or any Subsidiary of the Borrower or any other


 


72

















 


party any amount upon the
Guarantor Claims during the occurrence and continuance of an Event of Default.


 


Section 8.10       Claims
in Bankruptcy. In the event of receivership, bankruptcy, reorganization,
arrangement, debtor’s relief, or other insolvency proceedings involving the
Borrower or any Subsidiary of the Borrower, as debtor, the Lenders shall have
the right to prove their claim in any proceeding, so as to establish their
rights hereunder and receive directly from the receiver, trustee or other court
custodian, dividends and payments which would otherwise be payable upon
Guarantor Claims.  Each Guarantor hereby
assigns such dividends and payments to the Lenders. Should the Administrative
Agent or any Lender receive, for application upon the Obligations, any such
dividend or payment which is otherwise payable to any Guarantor, and which, as
between the Borrower or any Subsidiary of the Borrower and any Guarantor, shall
constitute a credit upon the Guarantor Claims, then upon payment in full of the
Obligations, such Guarantor shall become subrogated to the rights of the
Lenders to the extent that such payments to the Lenders on the Guarantor Claims
have contributed toward the liquidation of the Obligations, and such
subrogation shall be with respect to that proportion of the Obligations which
would have been unpaid if the Administrative Agent or a Lender had not received
dividends or payments upon the Guarantor Claims.


 


Section 8.11       Payments
Held in Trust.  In the event that
notwithstanding Sections 8.09 and 8.10 above, any Guarantor should receive any
funds, payments, claims or distributions which is prohibited by such Sections,
such Guarantor agrees to hold in trust for the Lenders an amount equal to the
amount of all funds, payments, claims or distributions so received, and agrees
that it shall have absolutely no dominion over the amount of such funds,
payments, claims or distributions except to pay them promptly to the
Administrative Agent, and each Guarantor covenants promptly to pay the same to
the Administrative Agent.


 


Section 8.12       Liens
Subordinate. Each Guarantor agrees that any liens, security interests, judgment
liens, charges or other encumbrances upon the Borrower’s or any Subsidiary of
the Borrower’s assets securing payment of the Guarantor Claims shall be and
remain inferior and subordinate to any liens, security interests, judgment
liens, charges or other encumbrances upon the Borrower’s or any Subsidiary of
the Borrower’s assets securing payment of the Obligations, regardless of
whether such encumbrances in favor of any Guarantor, the Administrative Agent
or the Lenders presently exist or are hereafter created or attach.


 


Section 8.13       Guarantor’s
Enforcement Rights. Without the prior written consent of the Lenders, no
Guarantor shall (a) exercise or enforce any creditor’s right it may have
against the Borrower or any Subsidiary of the Borrower, or (b) foreclose,
repossess, sequester or otherwise take steps or institute any action or
proceeding (judicial or otherwise, including without limitation the
commencement of or joinder in any liquidation, bankruptcy, rearrangement,
debtor’s relief or insolvency proceeding) to enforce any lien, mortgages, deeds
of trust, security interest, collateral rights, judgments or other encumbrances
on assets of the Borrower or any Subsidiary of the Borrower held by Guarantor.

ARTICLE IX



THE ADMINISTRATIVE AGENT AND THE ISSUING LENDER


 


Section 9.01       Authorization
and Action.  Each Lender hereby
appoints and authorizes the Administrative Agent to take such action as agent
on its behalf and to exercise such powers under this Agreement as are delegated
to the Administrative Agent by the terms hereof and of the other Loan
Documents, together with such powers as are reasonably incidental thereto.  As to any matters not expressly provided for
by this Agreement or any other Loan Document (including, without limitation,
enforcement or collection of the Notes), the Administrative Agent shall not be
required to exercise any discretion or take any action, but shall be required
to act or to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Majority Lenders, and such
instructions shall be binding upon all Lenders and all holders of Notes; provided,
however, that the Administrative Agent shall not be required to take any action
which exposes the Administrative Agent to personal liability or which is
contrary to this Agreement, any other Loan Document, or applicable law.


 


Section 9.02       Administrative Agent’s Reliance, Etc.  Neither
the Administrative Agent nor any of its directors, officers, agents, or
employees shall be liable for any action taken or omitted to be taken (including the Administrative Agent’s own
negligence) by it or them under or in connection with this
Agreement or the other Loan Documents, except for its or their own gross
negligence or willful misconduct. 
Without limitation of the generality of the foregoing, the
Administrative Agent:  (a) may treat the
payee of any Note as the holder thereof until the Administrative Agent receives
written notice of the assignment or transfer thereof signed by such payee and
in form satisfactory to the Administrative Agent; (b) may consult with legal
counsel (including counsel for any Credit Party), independent public
accountants, and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants, or experts; (c) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties, or representations made in or in connection with this
Agreement or the other Loan Documents; (d) shall not, except with respect to
Administrative Agent’s receipt of payments due hereunder, have any duty to
ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions of this Agreement or any other Loan Document on
the part of any Credit Party or to inspect the property (including the books
and records) of any Credit Party; (e) shall not be responsible to any Lender
for the due execution, legality, validity, enforceability, genuineness,
sufficiency, or value of this Agreement or any other Loan Document; and (f)
shall incur no liability under or in respect of this Agreement or any other
Loan Document by acting upon any notice, consent, certificate, or other
instrument or writing (which may be by telecopier or telex) believed by it to
be genuine and signed or sent by the proper party or parties.


 


Section 9.03       The
Administrative Agent and Its Affiliates. 
With respect to its Commitments, the Advances made by it and the Notes
issued to it, the Administrative Agent shall have the same rights and powers
under this Agreement as any other Lender and may exercise the same as though it
were not the Administrative Agent.  The
term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include
the Administrative Agent in its individual capacity.  The Administrative Agent and its Affiliates may accept deposits
from, lend


 


74

















 


money to, act as trustee under
indentures of, and generally engage in any kind of business with, any Credit
Party, and any Person who may do business with or own securities of any Credit
Party, all as if the Administrative Agent were not an agent hereunder and
without any duty to account therefor to the Lenders.


 


Section 9.04          Lender
Credit Decision.  Each Lender
acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender and based on the Financial Statements
and such other 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 shall,
independently and without reliance upon the Administrative Agent or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement.


 


Section 9.05          Indemnification.  The Lenders severally agree
to indemnify the Administrative Agent and the Issuing Lender and each Affiliate
thereof and their respective directors, officers, employees, and agents (to the
extent not reimbursed by the Credit Parties), according to their respective Pro
Rata Shares from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, or
disbursements of any kind or nature whatsoever which may be imposed on,
incurred by, or asserted against the Administrative Agent and the Issuing
Lender in any way relating to or arising out of this Agreement or any action
taken or omitted by the Administrative Agent or the Issuing Lender under this
Agreement or any other Loan Document (including the Administrative Agent’s and
the Issuing Lender’s own negligence), and including, without limitation,
environmental liabilities, provided that no Lender shall be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses, or disbursements resulting from the
Administrative Agent’s or the Issuing Lender’s gross negligence or willful
misconduct.  Without limitation of the
foregoing, each Lender agrees to reimburse the Administrative Agent and the
Issuing Lender promptly upon demand for its ratable share of any out-of-pocket
expenses (including counsel fees) incurred by the Administrative Agent or the
Issuing Lender in connection with the preparation, execution, delivery,
administration, modification, amendment, or enforcement (whether through
negotiations, legal proceedings, or otherwise) of, or legal advice in respect
of rights or responsibilities under, this Agreement or any other Loan Document,
to the extent that the Administrative Agent or the Issuing Lender is not
reimbursed for such by the Credit Parties, provided that no Lender shall be
liable for any portion of such out-of-pocket expenses (including counsel fees)
incurred by the Administrative Agent or the Issuing Bank as a result of the Administrative
Agent’s or the Issuing Lender’s gross negligence or willful misconduct.


 


Section 9.06          Successor
Administrative Agent and Issuing Lender. 
The Administrative Agent or the Issuing Lender may resign at any time by
giving written notice thereof to the Lenders and the Borrower and may be
removed at any time with or without cause by the Majority Lenders upon receipt
of written notice from the Majority Lenders to such effect.  Upon


 


75

















 


receipt of notice of any such
resignation or removal, the Majority Lenders shall have the right to appoint a
successor Administrative Agent or Issuing Lender with, if any Event of Default
has not occurred and is not continuing, the consent of the Borrower, which
consent shall not be unreasonably withheld. 
If no successor Administrative Agent or Issuing Lender shall have been
so appointed by the Majority Lenders with the consent of the Borrower, and
shall have accepted such appointment, within 30 days after the resigning Administrative
Agent’s or Issuing Lender’s giving of notice of resignation or the Majority
Lenders’ removal of the resigning Administrative Agent or Issuing Lender, then
the resigning Administrative Agent or Issuing Lender may, on behalf of the
Lenders and the Borrower, appoint a successor Administrative Agent or Issuing
Lender, which shall be, in the case of a successor agent, a Lender or any other
commercial bank organized under the laws of the United States of America or of
any State thereof and having a combined capital and surplus of at least
$500,000,000.00 and, in the case of the Issuing Lender, a Lender.  Upon the acceptance of any appointment as
Administrative Agent or Issuing Lender by a successor Administrative Agent or
Issuing Lender, such successor Administrative Agent or Issuing Lender shall
thereupon succeed to and become vested with all the rights, powers, privileges,
and duties of the resigning Administrative Agent or Issuing Lender, and the
resigning Administrative Agent or Issuing Lender shall be discharged from its
duties and obligations under this Agreement and the other Loan Documents,
except that the resigning Issuing Lender shall remain the Issuing Lender with
respect to any Letters of Credit outstanding on the Closing Date of its resignation
or removal and the provisions affecting the Issuing Lender with respect to such
Letters of Credit shall inure to the benefit of the resigning Issuing Lender
until the termination of all such Letters of Credit.  After any resigning Administrative Agent’s or Issuing Lender’s
resignation or removal hereunder as Administrative Agent or Issuing Lender, the
provisions of this Article IX shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent or Issuing
Lender under this Agreement and the other Loan Documents.


 


Section 9.07          Other
Agents.  None of the Lead Arranger,
the Co-Arranger, the Documentation Agent or the Syndication Agent, in such
respective capacities, shall have any duties or responsibilities, or incur any
liabilities, under this Agreement or the other Loan Documents.


 


Section 9.08          Collateral
Matters.


 


(a)           The Administrative Agent is
authorized on behalf of the Lenders, without the necessity of any notice to or
further consent from the Lenders, from time to time, to take any actions with
respect to any Collateral or Security Instruments which may be necessary to
perfect and maintain Acceptable Security Interests in and Liens upon the
Collateral granted pursuant to the Security Instruments.  The Administrative Agent is further
authorized on behalf of the Lenders, without the necessity of any notice to or
further consent from the Lenders, from time to time, to take any action in
exigent circumstances as may be reasonably necessary to preserve any rights or
privileges of the Lenders under the Loan Documents or applicable Legal
Requirements.


 


(b)           Each of the Lenders irrevocably
authorizes the Administrative Agent to release any Lien granted to or held by
the Administrative Agent upon any Collateral (i) upon termination of the
Commitments and payment in full of all outstanding Advances and all other
Obligations payable under this Agreement and under any other Loan Document;
(ii) constituting property


 


76

















 


sold or to be sold or disposed
of as part of or in connection with any disposition permitted under this
Agreement or the other Loan Documents; (iii) constituting property in which any
Credit Party owned no interest at the time the Lien was granted or at any time
thereafter; (iv) constituting Oil and Gas Properties to which no Proven
Reserves are attributed that currently encumbered under the Mortgage
Amendments; (v) if approved, authorized or ratified in writing by the Majority
Lenders or all the Lenders, as the case may be, as required by Section 10.01 or
(vi) as otherwise permitted by this Agreement. 
Upon the request of the Administrative Agent at any time, the Lenders
will confirm in writing the Administrative Agent’s authority to release
particular types or items of Collateral pursuant to this Section 9.08.  The Administrative Agent hereby agrees, from
time to time upon the prior written request of the Borrower, to execute and
deliver such releases and/or termination documents as may be necessary to effectively
release any and all of the Liens granted to or held by the Administrative Agent
upon any Collateral described in this Section 9.08(b).


 


(c)           The powers conferred on the
Administrative Agent under this Agreement and the other Security Instruments are
solely to protect its interest in the Collateral and shall not impose any duty
upon it to exercise any such powers. 
Except for the reasonable care of any Collateral in its possession and
the accounting for monies or other property actually received by it hereunder,
the Administrative Agent shall have no duty as to any Collateral or as to the
taking of any necessary steps to preserve rights against prior parties or any
other rights pertaining to any Collateral. 
The Administrative Agent shall be deemed to have exercised reasonable
care as to the custody and preservation of the Collateral in its possession if
the Collateral is accorded treatment substantially equal to that which the
Administrative Agent accords its own property, provided that the Administrative
Agent shall have no responsibility for taking any necessary steps to preserve
rights against any parties with respect to any Collateral.

Administrative Agent, the Issuing Lender, and each Lender and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights or delegate its duties under this Agreement or any interest
in this Agreement without the prior written consent of each Lender.


 


Section 10.06        Lender
Assignments and Participations.


 


(a)           Assignments.  Any Lender may assign to one or more banks
or other entities all or any portion of its rights and obligations under this
Agreement (including, without limitation, all or a portion of its Commitments,
the Advances owing to it, the Notes held by it, and the participation interest
in the Letter of Credit Obligations held by it); provided, however, that
(i) the amount of the Commitments and 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 be, if to an entity other
than a Lender, not less than $5,000,000.00, (ii) each such assignment shall be to
an Eligible Assignee, (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, together with the Notes subject to
such assignment, 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 administrative fee.  Any such assignment need not be ratable as among the
Facilities.  Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, which effective date shall be at least three
Business Days after the execution thereof unless otherwise waived by the
Administrative Agent in its sole discretion, (A) the assignee thereunder shall
be a party hereto for all purposes and, to the extent that rights and
obligations


 


79

















 


hereunder have been assigned to
it pursuant to such Assignment and Acceptance, have the rights and obligations
of a Lender hereunder and (B) such 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).


 


(b)           Term of Assignments.  By executing and delivering an Assignment
and Acceptance, the Lender thereunder and the assignee thereunder confirm to
and agree with each other and the other parties hereto as follows:  (i) other than as provided in such Assignment
and Acceptance, such Lender makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made in or in connection with this Agreement or the execution, legality,
validity, enforceability, genuineness, sufficiency of value of this Agreement
or any other instrument or document furnished pursuant hereto; (ii) such Lender
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of any Credit Party or the performance or observance
by the Borrower or its Subsidiaries of any of their obligations under this
Agreement or any other instrument or document furnished pursuant hereto; (iii)
such assignee confirms that it has received a copy of this Agreement, together
with copies of the most recently delivered financial statements pursuant to
Section 5.06 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Administrative Agent, such Lender or any other Lender and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement; (v) such assignee appoints and authorizes the
Administrative Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Administrative Agent
by the terms hereof, together with such powers as are reasonably incidental
thereto; and (vi) such assignee agrees that it will perform in accordance with
their terms all of the obligations which by the terms of this Agreement are
required to be performed by it as a Lender.


 


(c)           The Register.  The Administrative Agent shall maintain at
its address referred to in Section 10.02 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
Credit Parties, the Administrative Agent, the Issuing Lender, 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.


 


(d)           Procedures.  Upon its receipt of an Assignment and
Acceptance executed by a Lender and an Eligible Assignee, together with the
Notes subject to such assignment, the Administrative Agent shall, if such
Assignment and Acceptance has been completed and is in substantially the form
of the attached Exhibit A, (i) accept such Assignment and Acceptance,
(ii) record the information contained therein in the Register, and (iii) give
prompt notice thereof to 


 


80

















 


the Borrower.  Within five Business Days after its receipt
of such notice, the Borrower shall execute and deliver to the Administrative
Agent in exchange for the surrendered Notes (A) if such Eligible Assignee has
acquired a Commitment, a new Note to the order of such Eligible Assignee in an
amount equal to such Commitment assumed by it pursuant to such Assignment and
Acceptance and (B) if such Lender has retained any Commitment hereunder, a new
Note to the order of such Lender in an amount equal to the Commitment retained
by it hereunder.  Such new Note shall be
dated the effective date of such Assignment and Acceptance and shall otherwise

(e)           Participations.  Each Lender may sell participations to one
or more banks or other entities in or to all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitments, the Advances owing to it, its participation
interest in the Letter of Credit Obligations, and the Notes held by it); provided,
however, that (i) such Lender’s obligations under this Agreement (including,
without limitation, its Commitments to the Borrower hereunder) shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) such Lender shall
remain the holder of any such Notes for all purposes of this Agreement, (iv)
the Credit Parties, the Administrative Agent, and the Issuing Lender and the
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement, and
(v) such Lender shall not require the participant’s consent to any matter under
this Agreement, except for change in the principal amount of the Notes,
reductions in fees or interest, releasing all or substantially all of any
Collateral or Brigham Exploration or the General Partner as a Guarantor,
permitting any Credit Party to enter into any merger or consolidation with or
into any other (except as permitted hereby), 
postponement of any date fixed for any payment of principal of, or
interest on, the Notes or any fees or other amounts payable hereunder, or
extensions of either the Maturity Date or the Commitment Termination Date.  The Borrower hereby agrees that participants
shall have the same rights under Sections 2.12, 2.13, 2.14, and 11.07 as a
Lender to the extent of their respective participations.


 


Section 10.07        Indemnification.  The Borrower shall indemnify
the Arrangers, the Agents, the Lenders, the Issuing Lender, and each Affiliate
thereof and their respective directors, officers, employees, and agents from,
and discharge, release, and hold each of them harmless against, any and all
losses, liabilities, claims, or damages which may be imposed on, incurred by,
or asserted against them in any way relating to or arising out of this
Agreement or any action taken or omitted by them under this Agreement or any
other Loan Document (including any such losses, liabilities, claims, damages,
or expense incurred by reason of the person being indemnified’s own negligence
or strict liability) and including without limitation Environmental
Liabilities, but excluding any such losses, liabilities, claims, damages, or
expenses incurred by reason of the gross negligence or willful misconduct of
the person to be indemnified.


 


Section 10.08        Execution
in Counterparts.  This Agreement may
be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.


 


81

















 


Section 10.09        Survival
of Representations, Etc.  All
representations and warranties contained in this Agreement or made in writing
by or on behalf of the Borrower in connection herewith shall survive the
execution and delivery of this Agreement and the Loan Documents, the making of
the Advances and any investigation made by or on behalf of the Lenders, none of
which investigations shall diminish any Lender’s right to rely on such
representations and warranties.  All
obligations of the Borrower provided for in Sections 2.12, 2.13, 2.14(c),
10.04, and 10.07 and all of the obligations of the Lenders in Section 10.05
shall survive any termination of this Agreement and repayment in full of the
Obligations.


 


Section 10.10        Severability.  In case one or more provisions of this
Agreement or the other Loan Documents shall be invalid, illegal or
unenforceable in any respect under any applicable law, the validity, legality,
and enforceability of the remaining provisions contained herein or therein
shall not be affected or impaired thereby.


 


Section 10.11        Governing
Law.  Except as otherwise
expressly stated in any Security Instrument, this Agreement, the Notes and the
other Loan Documents shall be governed by, and construed and enforced in
accordance with, the laws of the State of New York.  Each Letter of Credit shall be governed by either (a) the Uniform
Customs and Practice for Documentary Credits (1993 Revision), International
Chamber of Commerce Publication No.  500
(or any successor to such publication) or (b) the International Standby
Practices 1998, Institute of International Banking Law & Practice (or any
successor to such publication).

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


 


82

















 


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


 


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


 


Section 10.13 WAIVER OF
JURY TRIAL.  EACH OF THE
CREDIT PARTIES, THE LENDERS, THE ISSUING LENDER, THE ARRANGERS AND THE AGENTS

IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN
DOCUMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

AGREEMENTS OF THE PARTIES.  THERE ARE NO
UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES HERETO.


 


Section 10.15 Dissemination
of Information.  Each of the Agents and the Lenders agrees to
maintain the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its Affiliates’ directors, officers,
employees and agents, including accountants, legal counsel and other advisors

extent required by applicable Legal Requirements or by any subpoena or similar
legal process; (d) to any other party to this Agreement; (e) to the extent
required, in connection with the exercise of any remedies hereunder or any suit,

containing provisions substantially the same as those of this Section 10.15 or
any other confidentiality obligation referred to herein, to (i) any participant

extent such Information (i) becomes publicly available other than as a result
of a breach of this Section or (ii) becomes available to any Agent or Lender on
a nonconfidential basis from a source other than any Credit Party.  In addition, any Agent or any Lender may
disclose the existence of this Agreement and information about this Agreement
to market data collectors, similar service providers to the lending industry,
and service providers to the Agents and the Lenders in connection with the
administration and management of this Agreement, the other Loan Documents, and
the Advances.  For the purposes of this
Section, “Information” means all information received from, or on behalf of,
any Credit Parties relating to any Credit Party or their business, other than
any such information that is 


 


83

















 


available to any Agent or any
Lender on a nonconfidential basis prior to disclosure by any Credit Party;
provided that, in the case of information received from any Credit Party after
the date hereof, such information is clearly identified in writing at the time
of delivery as confidential; provided, however, that
notwithstanding the foregoing, each Engineering Report shall be deemed to be
confidential regardless of whether such Engineering Report is identified in
writing 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.


 


Section 10.16        Production
Proceeds.  Notwithstanding that, by
the terms of the various Security Instruments, the Credit Parties are and will
be assigning to the Administrative Agent and the Lenders all of the “Production
Proceeds” (as defined therein) accruing to the Property covered thereby, so
long as no Event of Default has occurred the Credit Parties may continue to
receive from the purchasers of production all such Production Proceeds,
subject, however, to the Liens created under the Security Instruments, which
Liens are hereby affirmed and ratified. 
Upon the occurrence of an Event of Default, the Administrative Agent and
the Lenders may exercise all rights and remedies granted under the Security
Instruments, including the right to obtain possession of all Production
Proceeds then held by the Credit Parties or to receive directly from the
purchasers of production all other Production Proceeds.  In no case shall any failure, whether
intentional or inadvertent, by the Administrative Agent or the Lenders to
collect directly any such Production Proceeds constitute in any way a waiver,
remission or release of any of their rights under the Security Instruments, nor
shall any release of any Production Proceeds by the Administrative Agent or the
Lenders to the Credit Parties constitute a waiver, remission, or release of any
other Production Proceeds or of any rights of the Administrative Agent or the
Lenders to collect other Production Proceeds thereafter.


 


Section 10.17        Amendment
and Restatement.  The Borrower, the
Agents and the Lenders have agreed that this Agreement is an amendment and
restatement of the Existing Senior Credit Agreement in its entirety and the
terms and provisions hereof supersede the terms and provisions thereof, and

Existing Senior Credit Agreement.

and its Pro Rata Share of the Letter of Credit Exposure is
$                       ;
(ii) represents and warrants that it is the legal and beneficial owner of the
interest being assigned by it hereunder and that such interest is free and
clear of any adverse claim; (iii) makes no representation or warranty and
assumes no responsibility with respect to any statements, warranties, or

genuineness, sufficiency, or value of the Credit Agreement or any other Loan
Document or any other instrument or document furnished pursuant thereto; (iv)
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of any Credit Party or the performance or observance
by any Credit Party of any of its respective obligations under the Credit
Agreement or any other Loan Document or any other instrument or document

$                       
payable to the order of the Assignee and [a new Note dated
                       ,            in

analysis and decision to enter into this Assignment and Acceptance; (ii) agrees
that it will, independently and without reliance upon the Administrative Agent,

Mortgagee, its successors and assigns, all of the Hydrocarbons and all products
obtained or processed therefrom, and the revenues and proceeds now and
hereafter attributable to the Hydrocarbons and said products and all payments
in lieu of the Hydrocarbons such as “take or pay” payments or settlements,
together with the immediate and continuing right to collect and receive all of

The


 


8

purchaser thereof, to the credit of Mortgagee, free and clear of all taxes,
charges, costs, and expenses; and all such revenues and proceeds shall be paid
directly to Mortgagee, at its banking quarters in New York, New York with no
duty or obligation of any party paying the same to inquire into the rights of
Mortgagee to receive the same, what application is made thereof, or as to any
other matter.  Mortgagor agrees to
perform all such acts, and to execute all such further assignments, transfers
and division orders, and other instruments as may be required or desired by
Mortgagee or any party in order to have said proceeds and revenues so paid to
Mortgagee.  Mortgagee is fully
authorized to receive and receipt for said revenues and proceeds; to endorse
and cash any and all checks and drafts payable to the order of Mortgagor or
Mortgagee for the account of Mortgagor received from or in connection with said
revenues or proceeds and to hold the proceeds thereof in a bank account as
additional collateral securing the Indebtedness; and to execute transfer and
division orders in the name of Mortgagor, or otherwise, with warranties binding
Mortgagor.  All proceeds received by
Mortgagee pursuant to this assignment shall be applied as provided in the other
Loan Documents.  Mortgagee shall not be
liable for any delay, neglect, or failure to effect collection of any proceeds
or to take any other action in connection therewith or hereunder; but Mortgagee
shall have the right, at its election, in the name of Mortgagor or otherwise,
to prosecute and defend any and all actions or legal proceedings deemed
advisable by Mortgagee in order to collect such funds and to protect the interests
of Mortgagee, and/or Mortgagor, with all costs, expenses and attorneys’ fees
incurred in connection therewith being paid by Mortgagor.  Mortgagor hereby appoints Mortgagee as its
attorney-in-fact to pursue any and all rights of Mortgagor to liens on and
security interests in the Hydrocarbons securing payment of proceeds of runs
attributable to the Hydrocarbons.  In
addition to the rights granted to Trustee and/or Mortgagee in this Mortgage,
Mortgagor hereby further transfers and assigns to Mortgagee any and all such
liens, security interests, financing statements or similar interests of
Mortgagor attributable to its interest in the Hydrocarbons and proceeds of runs
therefrom arising under or created by said statutory provision, judicial
decision or otherwise.  The power of
attorney granted to Mortgagee in this Section 2.01, being coupled with an
interest, shall be irrevocable so long as the Indebtedness or any part thereof
remains unpaid.


 


Section 2.02           Rights Under Texas Act.  Mortgagor hereby grants, sells, assigns,
sets over and mortgages unto Mortgagee during the term hereof, all of
Mortgagor’s rights and interests pursuant to the provisions of Section 9.343 of
the Texas Business and Commerce Code, hereby vesting in Mortgagee all of
Mortgagor’s rights as an interest owner to the continuing security interest in
and lien upon the Mortgaged Property.


 


Section 2.03           No Modification of Payment
Obligations.  Nothing herein
contained shall modify or otherwise alter the obligation of Mortgagor to make
prompt payment of all principal and interest owing on the Indebtedness when and
as the same become due regardless of whether the proceeds of the Hydrocarbons
are sufficient to pay the same and the rights provided in accordance with the
foregoing assignment provision shall be cumulative of all other security of any
and every character now or hereafter existing to secure payment of the
Indebtedness.


 


Section 2.04           Release from Liability;
Indemnification.  Administrative
Agent and its successors and assigns are hereby absolutely absolved from all
liability for failure to enforce collection of the proceeds from runs
attributable to the Hydrocarbons and from all other


 


9

















 


responsibility in connection
therewith, except the responsibility to account to Mortgagor for funds actually
received by Administrative Agent. 
Mortgagor agrees to indemnify and hold harmless Administrative Agent,
including, for purposes of this paragraph, Administrative Agent’s directors,
officers, partners, employees, and agents and any persons owned or controlled
by any affiliate of Administrative Agent, from and against all claims, demands,
liabilities, losses, damages (including, without limitation, consequential,
punitive, and special damages), causes of action, judgments, penalties, costs
and reasonable out-of-pocket expenses (including, without limitation,
reasonable attorneys’ fees and expenses) imposed upon, asserted against, or
incurred or paid by Administrative Agent by reason of the assertion that Administrative
Agent has received, either before or after payment in full of the Indebtedness,
funds from the production of Hydrocarbons. 
The foregoing indemnities shall not terminate upon the expiration,
termination, or cancellation of the Second Amended and Restated Credit
Agreement or this Mortgage, but shall survive such expiration, termination, or
cancellation, as well as any foreclosure of this Mortgage or any conveyance in
lieu of foreclosure, and the repayment of the Indebtedness and the discharge and
release of this Mortgage and any other documents evidencing and/or securing the
Indebtedness.  Without limiting the generality of the foregoing, it is the
intention of Mortgagor and Mortgagor hereby agrees that the foregoing
indemnities shall apply to each indemnified party with respect to all claims,
demands, liabilities, losses, damages (including, without limitation,
consequential, punitive, and special damages), causes of action, judgments,
penalties, costs, and expenses (including, without limitation, reasonable
attorneys’ fees and expenses) which in whole or in part are caused by or arise
out of the negligence of any indemnified party.  Notwithstanding the foregoing, however, the indemnities
set forth in this Section 2.04 shall not apply to any particular indemnified
party (but shall apply to the other indemnified parties) to the extent the
subject of the indemnification is caused by or arises out of the gross
negligence or willful misconduct of such pericular indemnified party.


 


Section 2.05           Absolute Obligation of Credit
Parties.  Nothing herein contained
shall detract from or limit the obligations of any Mortgagor or any other
Credit Party to make payment as required pursuant to the terms of the Loan
Documents, regardless of whether the assignment of production described in this
Article II is sufficient to pay same, and the rights under this Article II
shall be cumulative of all other rights of Administrative Agent and any other
Lender under the Loan Documents.


 


ARTICLE III


 


Representations, Warranties and Covenants


 


In order to
induce Administrative Agent and the Lenders to enter into the transactions
described in the Second Amended and Restated Credit Agreement, Mortgagor hereby
represents, warrants and covenants, to Trustee, Administrative Agent, each of
the Lenders, and to Mortgagee as follows:


 


Section 3.01           Title.  To the extent of the undivided interests in
the wells specified on attached Exhibit A, Mortgagor is possessed of
such interests in the Mortgaged Property, and Mortgagor has, and Mortgagor
covenants to maintain, good and indefeasible title to the Mortgaged
Property.  The Mortgaged Property is
free of any and all Liens (as defined in the


 


10

















 


Second Amended and Restated
Credit Agreement) except Permitted Liens (as defined in the Second Amended and
Restated Credit Agreement) and Liens, if any, described in Exhibit A
(collectively, the “Permitted Encumbrances”).


 


Section 3.02           Defend Title.  This Mortgage is, and always will be kept, a
direct first lien and security interest upon the Mortgaged Property subject
only to the Permitted Encumbrances, and, except for Permitted Encumbrances,
Mortgagor will not create or suffer to be created or permit to exist any lien,
security interest or charge prior or junior to or on a parity with the lien and
security interest of this Mortgage upon the Mortgaged Property or any part
thereof or upon the rents, issues, revenues, profits and other income
therefrom.  Mortgagor hereby warrants
and Mortgagor does by these presents agree to forever defend the Mortgaged
Property against the claims and demands of all other persons whomsoever and to
maintain and preserve the lien created hereby so long as any of the
Indebtedness secured hereby remains unpaid. 
Should an adverse claim be made against or a cloud develop upon the
title to any part of the Mortgaged Property, Mortgagor agrees it will
immediately defend against such adverse claim or take appropriate action to
remove such cloud at Mortgagor’s cost and expense, and Mortgagor further agrees
that Trustee and/or Mortgagee may take such other action as they deem advisable
to protect and preserve their interests in the Mortgaged Property, and in such
event Mortgagor will indemnify Trustee and Mortgagee against any and all cost,
attorney’s fees and other expenses which they may incur in defending against
any such adverse claim or taking action to remove any such cloud.


 


Section 3.03           Not a Foreign Person.  Mortgagor is not a “foreign person” within
the meaning of the Internal Revenue Code of 1986, as amended (hereinafter
called the “Code”), Sections 1445 and 7701 (i.e. Mortgagor is not a
non-resident alien, foreign corporation, foreign partnership, foreign trust or
foreign estate as those terms are defined in the Code and any regulations
promulgated thereunder).


 


Section 3.04           Existence; Power to Create Lien
and Security; Enforceable Obligations.


 


(a)           Mortgagor is duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its formation and in good standing and qualified to do business
in each jurisdiction where its ownership or lease of any of the Mortgaged
Property or conduct of its business requires such qualification and where the
failure to so qualify could reasonably be expected to cause a Material Adverse
Change.


 


(b)           The execution,
delivery, and performance by Mortgagor of this Mortgage and the consummation of
the transactions contemplated hereby and thereby (i) are within such
Mortgagor’s powers, (ii) have been duly authorized by all necessary governing
action, (iii) do not contravene (A) Mortgagor’s governance documents or (B) any
Legal Requirement or any material contractual restriction binding on or
affecting Mortgagor, and (iv) will not result in or require the creation or
imposition of any Lien upon any of the material Property of any Credit Party
prohibited by the Second Amended and Restated Credit Agreement.


 


(c)           This Mortgage has
been duly executed and delivered by Mortgagor. 
This Mortgage is the legal, valid, and binding obligation of Mortgagor
enforceable against


 


11

















 


Mortgagor in
accordance with its terms, except as such enforceability may be limited by any
applicable bankruptcy, insolvency, reorganization, moratorium, or similar law
affecting creditors’ rights generally and by general principles of equity.


 


Section 3.05           Net Revenue and Cost Bearing
Interest.  With respect to each well
listed on Exhibit A hereto which comprises a part of the Mortgaged
Property, Mortgagor’s ownership of such Mortgaged Property does and will, with
respect to each such well (whether such well is presently unitized or is
presently producing on a lease basis) (a) entitle Mortgagor to receive (subject

cause the owner or owners of the working interest in such properties to comply
with the covenants and agreements set forth in this Mortgage.


 


(c)           To the extent

and remedies as are reasonably available to Mortgagor (including, without

of title to the Mortgaged Property in extinguishment in whole or in part of the
Indebtedness, all right, title, and interest of Mortgagor in and to such

payable thereunder shall thereupon vest in the purchaser at such foreclosure or
Administrative Agent or other transferee in the event of such other transfer of
title.


 


Section 3.10           Further Assurances.  Mortgagor shall, and shall cause each of its
Subsidiaries to, cure promptly any defects in the execution and delivery of
this Mortgage or any of the other Loan Documents.  Mortgagor hereby authorizes the Administrative Agent to file any
financing statements without Mortgagor’s signature to the extent permitted by
applicable law in order to perfect or maintain the perfection of any security
interest granted under any of the Loan Documents.  Mortgagor at its expense will, and will cause each of its
Subsidiaries to, promptly execute and deliver to the Administrative Agent upon
request all such other documents, agreements and instruments to comply with or
accomplish the covenants and agreements of Mortgagor or any other Credit Party
in this Mortgage or any other Loan Document, or to further evidence and more
fully describe the collateral intended as security for Obligations, or to
correct any omissions in the Loan Documents, or to state more fully the
security obligations set out in this Mortgage or in any of the other Loan
Documents, or to perfect, protect or preserve any Liens created pursuant to any
of the Loan Documents, or to make any recordings, to file any notices or obtain
any consents, all as may be necessary or appropriate in connection therewith or
to enable the Administrative Agent to exercise and enforce its rights and

receipt from Mortgagee of written notice and demand,  fails to perform any act or to take any action which Mortgagor is
required to perform or take hereunder or pay any money which Mortgagor is
required to pay hereunder, each of Mortgagee and Trustee in Mortgagor’s name or
its or their own name may, but shall not be obligated to, perform or cause to
perform such act or take such action or pay such money, and any expenses so
incurred by either of them and any money so paid by either of them shall be a
demand obligation owing by Mortgagor to Mortgagee or Trustee, as the case may
be, and each of Mortgagee and Trustee, upon making such payment, shall be
subrogated to all of the rights of the Person receiving such payment.  Each amount due and owing by Mortgagor to
each of Mortgagee and Trustee pursuant to this Mortgage shall bear interest
from the date of such expenditure or payment or other occurrence which gives
rise to such amount being owed to such Person until paid at post-default
interest rate described in the


 


13

















 


Second Amended and Restated
Credit Agreement, and all such amounts together with such interest thereon
shall be a part of the Indebtedness described in Section 1.03 hereof.


 


Section 3.13           Waste.  Mortgagor shall not commit or permit any
waste, impairment, or deterioration of the Mortgaged Property or any part thereof.


 


ARTICLE IV


 


Rights and Remedies


 


Section 4.01           Event of Default.  An “Event of Default” under the
Second Amended and Restated Credit Agreement shall be an Event of Default under
this Mortgage.


 


Section 4.02           Foreclosure and Sale.


 


(a)           If an Event of Default
shall occur and be continuing, Mortgagee shall have the right and option to
proceed with foreclosure by proceeding or by directing Trustee, or his
successors or substitutes in trust, to proceed with foreclosure and to sell, to
the extent permitted by law, all or any portion of the Mortgaged Property at
one or more sales, as an entirety or in parcels, at such place or places in
otherwise such manner and upon such notice as may be required by law, or, in
the absence of any such requirement, as Mortgagee may deem appropriate, and to
make conveyance to the purchaser or purchasers.  Where the Mortgaged Property is situated in more than one county,
notice as above provided shall be posted and filed in all such counties (if
such notices are required by law), and all such Mortgaged Property may be sold
in any such county and any such notice shall designate the county where such
Mortgaged Property is to be sold. 
Nothing contained in this Section 4.02 shall be construed so as to limit
in any way Mortgagee’s or Trustee’s rights to sell the Mortgaged Property, or
any portion thereof, by private sale if, and to the extent that, such private
sale is permitted under the laws of the applicable jurisdiction or by public or
private sale after entry of a judgment by any court of competent jurisdiction
so ordering.  Mortgagor hereby
irrevocably appoints Trustee to be the attorney of Mortgagor and in the name
and on behalf of Mortgagor to execute and deliver any deeds, transfers, conveyances,
assignments, assurances and notices which Mortgagor ought to execute and
deliver and do and perform any and all such acts and things which Mortgagor
ought to do and perform under the covenants herein contained and generally, to
use the name of Mortgagor in the exercise of all or any of the powers hereby
conferred on Trustee.  At any such sale:
(i) whether made under the power herein contained or any other legal
enactment, or by virtue of any judicial proceedings or any other legal right,
remedy or recourse, it shall not be necessary for Mortgagee or Trustee to have
physically present, or to have constructive possession of, the Mortgaged
Property (Mortgagor hereby covenanting and agreeing to deliver to Mortgagee or
Trustee any portion of the Mortgaged Property not actually or constructively
possessed by Mortgagee or Trustee immediately upon demand by Mortgagee or
Trustee) and the title to and right of possession of any such property shall
pass to the purchaser thereof as completely as if the same had been actually
present and delivered to purchaser at such sale, (ii) each instrument of
conveyance executed by Mortgagee or Trustee shall contain a general warranty of
title, binding upon Mortgagor and its successors and assigns, (iii) each
and


 


14

















 


every recital
contained in any instrument of conveyance made by Mortgagee or Trustee shall
conclusively establish the truth and accuracy of the matters recited therein,
including, without limitation, nonpayment of the Indebtedness, advertisement
and conduct of such sale in the manner provided herein and otherwise by law and
appointment of any successor Trustee hereunder, (iv) any and all
prerequisites to the validity thereof shall be conclusively presumed to have
been performed, (v) the receipt of Mortgagee or Trustee or of such other
party or officer making the sale shall be a sufficient discharge to the
purchaser or purchasers for its purchase money and no such purchaser or
purchasers, or its assigns or personal representatives, shall thereafter be obligated
to see to the application of such purchase money, or be in any way answerable
for any loss, misapplication or nonapplication thereof, (vi) to the
fullest extent permitted by law, Mortgagor shall be completely and irrevocably
divested of all of its right, title, interest, claim and demand whatsoever,
either at law or in equity, in and to the property sold and such sale shall be
a perpetual bar both at law and in equity against Mortgagor, and against any
and all other persons claiming or to claim the property sold or any part
thereof, by, through or under Mortgagor, and (vii) to the extent and under
such circumstances as are permitted by law, Trustee, Mortgagee, or any Lender
may be a purchaser at any such sale, and shall have the right, after paying or accounting
for all costs of said sale or sales, to credit the amount of the bid upon the
amount of the Indebtedness held by such purchaser, if any (in the order of
priority set forth in Section 4.13 hereof) in lieu of cash payment.


 


(b)           With respect to any
portion of the Mortgaged Property located in the state of Oklahoma and with
respect any foreclosure by Mortgagor pursuant to the power of sale granted to
Mortgagor in this Mortgage the following provisions of this Mortgage shall
apply:


 


(i)            The notices described
in Section 40 and certain following sections of the Oklahoma Mortgage
Foreclosure Act, shall be given as and when required therein;


 


(ii)           All notices which
are required to be given to Mortgagor under the Oklahoma Mortgage Foreclosure
Act may be given to Mortgagor at the address which is set forth in the first
paragraph of this Mortgage, or if such address has been changed in accordance
with the express requirements of this Mortgage related to such a change of
address, to that changed address;


 


(iii)          Mortgagee may
purchase part or all of the Mortgaged Property at any such sale;


 


(iv)          Mortgagor stipulates
that the total amounts owing under this Mortgage benefit, have benefited, and
will benefit Mortgagor substantially and are not unconscionable in amount, and
therefore the total amount of the Indebtedness, less the fair market value of
the Mortgaged Property sold pursuant to the Oklahoma Mortgage Foreclosure Act,
and any prior indebtedness, shall be available as a deficiency judgment against
Mortgagor;


 


15

















 


(v)           The purchaser under
any sale of the Mortgaged Property conducted pursuant to the Oklahoma Mortgage
Foreclosure Act may seek and obtain a writ of assistance by application to the
District Court in the county in Oklahoma in which the portion of the Mortgaged
Property to be foreclosed upon is located, or the United States District Court
having venue for actions arising in such county;


 


(vi)          Mortgagee may, at
its option, proceed with foreclosure under judicial proceedings instead of
exercising the rights of the power of sale granted by Mortgagor to Mortgagee in
this Mortgage;


 


(vii)         All other terms,
conditions, procedures, and requirements of the Oklahoma Mortgage Foreclosure
Act shall be followed;


 


(viii)        After the completion
of the sale as contemplated by the Oklahoma Mortgage Foreclosure Act, the
purchaser shall have all of Mortgagor’s right, title and interest in and to
Mortgaged Property sold pursuant to such sale, free and clear of all rights of
Mortgagor, and free and clear of all rights of any person with a priority which
is subordinate to the lien of this Mortgage, except any right which may be
reserved under the Oklahoma Mortgage Foreclosure Act;


 


(ix)           Any recitation in
any notice, publication thereof, recordation thereof, or deed, of the existence
of an Event of Default, giving, publication, service and recordation of notice,
occurrence of the sale at the time and place set forth in such notice or any
postponement authorized and effective under the Oklahoma Mortgage Foreclosure
Act, circumstances of sale and bidding, and compliance with the terms of the
Oklahoma Mortgage Foreclosure Act, shall be presumed to be statements of fact
and no person shall be required to investigate the truthfulness or accuracy of
any such recitation; and


 


(x)            The proceeds of any
such sale shall be applied first to the costs, attorney fees, and expenses of
such sale, next to the payment of the Indebtedness; except that if such
application of proceeds conflicts with the requirements of the Oklahoma
Mortgage Foreclosure Act, the proceeds of such sale shall be applied as
provided under the Oklahoma Mortgage Foreclosure Act, but in such event, only
to the extent of any such conflict.


 


Section 4.03           Substitute Trustees and Agents.  Trustee or his successor or substitute may
appoint or delegate any one or more persons as agent to perform any act or acts
necessary or incident to any sale held by Trustee, including the posting of
notices and the conduct of sale, but in the name and on behalf of Trustee, his
successor or substitute.  If Trustee or
his successor or substitute shall have given notice of sale hereunder, any
successor or substitute trustee thereafter appointed may complete the sale and
the conveyance of the property pursuant thereto as if such notice had been
given by the successor or substitute trustee conducting the sale.


 


Section 4.04           Judicial Foreclosure; Receivership.


 


(a)           If any of the
Indebtedness shall become due and payable and shall not be promptly paid,
Trustee or Mortgagee shall have the right and power to proceed by a suit


 


16

















 


or suits in
equity or at law, whether for the specific performance of any covenant or
agreement herein contained or in aid of the execution of any power herein
granted, or for any foreclosure hereunder or for the sale of the Mortgaged
Property under the judgment or decree of any court or courts of competent
jurisdiction, or for the appointment of a receiver pending any foreclosure
hereunder or the sale of the Mortgaged Property under the order of a court or
courts of competent jurisdiction or under executory or other legal process, or
for the enforcement of any other appropriate legal or equitable remedy.  Any money advanced by Trustee and/or
Mortgagee in connection with any such receivership shall be a demand obligation
(which obligation Mortgagor hereby expressly promises to pay) owing by
Mortgagor to Trustee and/or Mortgagee and shall bear interest from the date of
making such advance by Trustee and/or Mortgagee until paid at the interest rate
applicable to periods following an Event of Default in the Second Amended and
Restated Credit Agreement.


 


(b)           If an action is
filed to foreclose this Mortgage, or if Mortgagee or Trustee seeks to foreclose
this Mortgage by power of sale under the Oklahoma Power of Sale Mortgage
Foreclosure Act, Mortgagee or Trustee, as applicable, shall be entitled to the
immediate appointment of a receiver pursuant to 12 Oklahoma Statutes
§1551(2)(c) without the necessity of further proof.


 


Section 4.05           Foreclosure for Installments.  Mortgagee shall also have the option to
proceed with foreclosure in satisfaction of any installments of the
Indebtedness which have not been paid when due either through the courts or by
directing Trustee or his successors in trust to proceed with foreclosure in
satisfaction of the matured but unpaid portion of the Indebtedness as if under
a full foreclosure, conducting the sale as herein provided and without
declaring the entire principal balance and accrued interest due; such sale may
be made subject to the unmatured portion of the Indebtedness, and any such sale
shall not in any manner affect the unmatured portion of the Indebtedness, but
as to such unmatured portion of the Indebtedness this Mortgage shall remain in
full force and effect just as though no sale had been made hereunder.  It is further agreed that several sales may
be made hereunder without exhausting the right of sale for any unmatured part
of the Indebtedness, it being the purpose hereof to provide for a foreclosure
and sale of the security for any matured portion of the Indebtedness without
exhausting the power to foreclose and sell the Mortgaged Property for any
subsequently maturing portion of the Indebtedness.


 


Section 4.06           Separate Sales.  The Mortgaged Property may be sold in one or
more parcels and in such manner and order as Mortgagee, in its sole discretion,
may elect, it being expressly understood and agreed that the right of sale
arising out of any Event of Default shall not be exhausted by any one or more
sales.


 


Section 4.07           Occupancy After Foreclosure.  In the event there is a foreclosure sale
hereunder and at the time of such sale Mortgagor or Mortgagor’s heirs,
devisees, representatives, successors or assigns or any other person claiming
any interest in the Mortgaged Property by, through or under Mortgagor, are
occupying or using the Mortgaged Property or any part thereof, each and all
shall immediately become the tenant of the purchaser at such sale, which tenancy
shall be a tenancy from day to day, terminable at the will of either the
landlord or tenant, or at a reasonable rental per day based upon the value of
the property occupied, such rental to be due


 


17

















 


daily to the purchaser; to the
extent permitted by applicable law, the purchaser at such sale shall,
notwithstanding any language herein apparently to the contrary, have the sole
option to demand immediate possession following the sale or to permit the occupants
to remain as tenants at will.  In the
event the tenant fails to surrender possession of said property upon demand,
the purchaser shall be entitled to institute and maintain a summary action for
possession of the Mortgaged Property (such as an action for forcible entry and
detainer) in any court having jurisdiction.


 


Section 4.08           Remedies Cumulative, Concurrent
and Nonexclusive.  Every right,
power and remedy herein given to Trustee or Mortgagee shall be cumulative and
in addition to every other right, power and remedy herein specifically given or
now or hereafter existing in equity, at law or by statute (including
specifically those granted by the Applicable UCC in effect and applicable to
the Mortgaged Property or any portion thereof) each and every right, power and
remedy whether specifically herein given or otherwise existing may be exercised
from time to time and so often and in such order as may be deemed expedient by
Trustee or Mortgagee, and the exercise, or the beginning of the exercise, of
any such right, power or remedy shall not be deemed a waiver of the right to
exercise, at the same time or thereafter any other right, power or remedy.  No delay or omission by Trustee or Mortgagee
in the exercise of any right, power or remedy shall impair any such right,
power or remedy or operate as a waiver thereof or of any other right, power or
remedy then or thereafter existing.


 


Section 4.09           No Release of Obligations.  Neither Mortgagor, any Guarantor, any other
guarantor of the Indebtedness, nor any other person hereafter obligated for
payment of all or any part of the Indebtedness shall be relieved of such
obligation by reason of (a) the failure of Trustee or Mortgagee to comply with
any request of Mortgagor, or any guarantor or any other person so obligated to
foreclose the lien of this Mortgage or to enforce any provision hereunder or
under the Second Amended and Restated Credit Agreement; (b) the release,
regardless of consideration, of the Mortgaged Property or any portion thereof
or interest therein or the addition of any other property to the Mortgaged
Property; (c) any agreement or stipulation between any subsequent owner of the
Mortgaged Property and Mortgagee extending, renewing, rearranging or in any
other way modifying the terms of this Mortgage without first having obtained
the consent of, given notice to or paid any consideration to Mortgagor, any
guarantor or such other person, and in such event Mortgagor, guarantor and all
such other persons shall continue to be liable to make payment according to the
terms of any such extension or modification agreement unless expressly released
and discharged in writing by Mortgagee; or (d) by any other act or occurrence
save and except the complete payment of the Indebtedness and the complete
fulfillment of all obligations hereunder or under the Second Amended and
Restated Credit Agreement.


 


Section 4.10           Release of and Resort to Mortgaged
Property.  Mortgagee may release,
regardless of consideration, any part of the Mortgaged Property without, as to
the remainder, in any way impairing, affecting, subordinating or releasing the
lien or security interest created in or evidenced by this Mortgage or its
stature as a first and prior lien and security interest in and to the Mortgaged
Property, and without in any way releasing or diminishing the liability of any
person or entity liable for the repayment of the Indebtedness.  For payment of the Indebtedness, Mortgagee
may resort to any other security therefor held by Mortgagee or Trustee in such
order and manner as Mortgagee may elect.


 


18

















 


Section 4.11           Waiver of Redemption, Notice and
Marshalling of Assets, Etc.  To the
fullest extent permitted by law, Mortgagor hereby irrevocably and
unconditionally waives and releases (a) all benefits that might accrue to
Mortgagor by virtue of any present or future moratorium law or other law
exempting the Mortgaged Property from attachment, levy or sale on execution or
providing for any appraisement, valuation, stay of execution, exemption from
civil process, redemption or extension of time for payment and (b) any right to
a marshalling of assets or a sale in inverse order of alienation.  If any law referred to in this Mortgage and
now in force, of which Mortgagor or its successor or successors might take
advantage despite the provisions hereof, shall hereafter be repealed or cease
to be in force, such law shall thereafter be deemed not to constitute any part
of the contract herein contained or to preclude the operation or application of
the provisions hereof.  Provided,
however, that if the laws of any state do not permit the redemption period to
be waived, the redemption period is specifically reduced to the minimum amount
of time allowable by statute.  With
respect to any portion of the Mortgaged Property located in the state of
Oklahoma, Mortgagee and Trustee hereby waive or do not waive appraisement, such
election to be made at or before entry of judgment in any action to foreclose
this Mortgage; provided, however,
such waiver or non-waiver shall not affect Mortgagor’s waiver of such rights,
which shall be absolute.


 


Section 4.12           Discontinuance of Proceedings  In case Mortgagee shall have proceeded to
invoke any right, remedy or recourse permitted hereunder or under the Second
Amended and Restated Credit Agreement and shall thereafter elect to discontinue
or abandon same for any reason, Mortgagee shall have the unqualified right so
to do and, in such an event, Mortgagor and Mortgagee shall be restored to their
former positions with respect to the Indebtedness, this Mortgage, the Second
Amended and Restated Credit Agreement, the Mortgaged Property and otherwise,
and the rights, remedies, recourses and powers of Mortgagee shall continue as
if same had never been invoked.


 


Section 4.13           Application of Proceeds.  The proceeds of any sale of the Mortgaged
Property or any part thereof and all other monies received by Trustee or
Mortgagee in any proceedings for the enforcement hereof or otherwise, whose
application has not elsewhere herein been specifically provided for, shall be
applied:


 


(a)           first, to the
payment of all reasonable expenses incurred by Trustee or Mortgagee incident to
the enforcement of this Mortgage, the Second Amended and Restated Credit
Agreement or any of the Indebtedness (including, without limiting the
generality of the foregoing, expenses of any entry or taking of possession, of
any sale, of advertisement thereof, and of conveyances, and court costs,
compensation of agents and employees, legal fees and a reasonable commission to
Trustee acting), and to the payment of all other charges, reasonable expenses,
liabilities and advances incurred or made by Trustee or Mortgagee under this
Mortgage or in executing any trust or power hereunder;


 


(b)           second to payment of
the Indebtedness in the order and manner required in the Second Amended and
Restated Credit Agreement; and


 


(c)           third, to Mortgagor
or as otherwise required by any Governmental Requirement.


 


19

















 


Section 4.14           Resignation of Operator.  In addition to all rights and remedies under
this Mortgage, at law and in equity, if any Event of Default shall occur and
Trustee or Mortgagee shall exercise any possessory remedies under this Mortgage
with respect to any portion of the Hydrocarbon Property (or Mortgagor shall
transfer any Mortgaged Property “in lieu of” foreclosure), Mortgagee or Trustee
shall have the right to request that any operator of any Hydrocarbon Property
which is either Mortgagor or any Affiliate of Mortgagor to resign as operator
under the joint operating agreement applicable thereto, and no later than 60
days after receipt by Mortgagor of any such request, Mortgagor shall resign (or
cause such other party to resign) as operator of such Hydrocarbon Property.


 


Section 4.15           Indemnity.  In connection with any action taken by
Trustee and/or Mortgagee pursuant to this Mortgage, Trustee and/or Mortgagee
and their officers, directors, employees, representatives, agents, attorneys,
accountants and experts (“Indemnified Parties”) shall not be liable for
any loss sustained by Mortgagor resulting from an assertion that Mortgagee has
received funds from the production of Hydrocarbons claimed by third persons or
any act or omission of any Indemnified Party in administering, managing,
operating or controlling the Mortgaged Property INCLUDING SUCH LOSS WHICH MAY RESULT FROM THE NEGLIGENCE OF AN INDEMNIFIED
PARTY  unless such
loss is caused by the gross negligence or willful misconduct of an Indemnified
Party, nor shall Trustee and/or Mortgagee be obligated to perform or discharge
any obligation, duty or liability of Mortgagor. Mortgagor shall and does hereby
agree to indemnify each Indemnified Party for, and to hold each Indemnified
Party harmless from, any and all liability, loss or damage which may or might
be incurred by any Indemnified Party by reason of this Mortgage or the exercise
of rights or remedies hereunder INCLUDING
SUCH LIABILITY, LOSS, OR DAMAGE WHICH MAY RESULT FROM THE NEGLIGENCE OF AN
INDEMNIFIED PARTY unless such liability, loss, or damage is
caused by the gross negligence or willful misconduct of an Indemnified Party;
should Trustee and/or Mortgagee make any expenditure on account of any such
liability, loss or damage, the amount thereof, including costs, expenses and
reasonable attorneys’ fees, shall be a demand obligation (which obligation
Mortgagor hereby expressly promises to pay) owing by Mortgagor to Trustee
and/or Mortgagee and shall bear interest from the date expended until paid at
the Post-Default Rate, shall be a part of the Indebtedness and shall be secured
by this Mortgage and any other Security Instrument.  Mortgagor hereby assents to, ratifies and confirms any and all
actions of Trustee and/or Mortgagee with respect to the Mortgaged Property
taken under, and in compliance with the terms of, this Mortgage.  The liabilities of Mortgagor as set forth in
this Section 4.15 shall survive the termination of this Mortgage.


 


ARTICLE V


 


Trustee


 


Section 5.01           Duties, Rights, and Powers of
Trustee.  It shall be no part of the
duty of Trustee to see to any recording, filing or registration of this
Mortgage or any other instrument in addition or supplemental thereto, or to
give any notice thereof, or to see to the payment of or be under any duty in
respect of any tax or assessment or other governmental charge which may be
levied or assessed on the Mortgaged Property, or any part thereof, or against
Mortgagor, or to see to the performance or observance by Mortgagor of any of
the covenants and agreements


 


20

















 


contained herein.  Trustee shall not be responsible for the
execution, acknowledgment or validity of this Mortgage or of any instrument in
addition or supplemental hereto or for the sufficiency of the security purported
to be created hereby, and makes no representation in respect thereof or in
respect of the rights of Mortgagee. 
Trustee shall have the right to advise with counsel upon any matters
arising hereunder and shall be fully protected in relying as to legal matters
on the advice of counsel.  Trustee shall
not incur any personal liability hereunder except for Trustee’s own gross
negligence, bad faith and/or willful misconduct; and Trustee shall have the
right to rely on any instrument, document or signature authorizing or
supporting any action taken or proposed to be taken by him hereunder, believed
by him in good faith to be genuine.


 


Section 5.02           Successor Trustee; Resignation by
Trustee.  Trustee may resign by
written notice addressed to Mortgagee or be removed at any time with or without
cause by an instrument in writing duly executed on behalf of Mortgagee.  In case of the death, resignation or removal
of Trustee, a successor trustee may be appointed by Mortgagee by instrument of
substitution complying with any applicable requirements of law, or, in the
absence of any such requirement, without other formality than appointment and
designation in writing.  Written notice
of such appointment and designation shall be given by Mortgagee to Mortgagor,
but the validity of any such appointment shall not be impaired or affected by
failure to give such notice or by any defect therein.  Such appointment and designation shall be full evidence of the
right and authority to make the same and of all the facts therein recited, and,
upon the making of any such appointment and designation, this Mortgage shall
vest in the successor trustee all the estate and title in and to all of the
Mortgaged Property, and the successor trustee shall thereupon succeed to all of
the rights, powers, privileges, immunities and duties hereby conferred upon
Trustee named herein, and one such appointment and designation shall not
exhaust the right to appoint and designate a successor trustee hereunder but
such right may be exercised repeatedly as long as any Indebtedness remains
unpaid hereunder.  To facilitate the

unenforceable in any jurisdiction, the other provisions hereof shall remain in
full force and effect in such jurisdiction and the remaining provisions hereof

effectuate the provisions hereof, and the invalidity or unenforceability of any
provision hereof in any jurisdiction shall not affect the validity or
enforceability of any such provision in any other jurisdiction.


 


Section 6.04           Successors and Assigns of Parties.  The term “Lender” as used herein shall mean
and include any legal owner, holder, assignee or pledgee of any of the
Indebtedness secured hereby.  The terms
used to designate Trustee, Mortgagee and Mortgagor shall be deemed to include
the respective heirs, legal representatives, successors and assigns of such
parties.


 


Section 6.05           Satisfaction of Prior Encumbrance.  To the extent that proceeds of the Second
Amended and Restated Credit Agreement are used to pay indebtedness secured by
any outstanding lien, security interest, charge or prior encumbrance against
the Mortgaged Property, such proceeds have been advanced by Mortgagee or any of
the other Lenders at Mortgagor’s request, and Mortgagee shall be subrogated to
any and all rights, security interests and liens owned by any owner or holder
of such outstanding liens, security interests, charges or encumbrances, and it
is expressly understood that, in consideration of the payment of such other
indebtedness by Mortgagee or any of the other Lenders, Mortgagor hereby waives

Mortgage or at such other address as shall be designated by such party in a
written notice to the other parties.

Section 6.09           Counterparts.  This Mortgage is being executed in several
counterparts, all of which are identical, except that to facilitate
recordation, if the Mortgaged Property is situated in more than one county,
descriptions of only those portions of the Mortgaged Property located in the
county in which a particular counterpart is recorded shall be attached as Exhibit
A thereto. A complete Exhibit A will be attached to that certain
counterpart that is filed in the real property records of
                             County,
Texas.  Each of such counterparts shall

liability inherent in some aspects of the transaction and relieving the other
party of its responsibility for such liability.  Each party hereto agrees and covenants that it will not contest
the validity or enforceability of any exculpatory provision of this Mortgage on
the basis that the party had no notice or knowledge of such provision or that
the provision is not “conspicuous.”


 


Section 6.11           Security Agreement.  With respect to any portion of the Mortgaged
Property which constitutes fixtures or other property governed by the
Applicable UCC, this Mortgage shall constitute a security agreement between

hereunder, Mortgagee shall have all of the rights conferred upon secured
parties by the Applicable UCC.

Mortgages; Effect of Mortgage.  The
conveyance and the granting of liens in the Original Mortgages is hereby
ratified, adopted, confirmed, and renewed. 
In addition, as stated in the Recitals to this Mortgage, this Mortgage
constitutes for all purposes an amendment and restatement of the Original
Mortgages and not a new or substitute security instrument.


 


Section 6.13           Time of the Essence.  Time is of the essence in the performance of
each and every obligation under this Mortgage.


 


Section 6.14           Authority of Administrative Agent.  The Lenders may, by agreement among them,

unless


 


23

















 


and until modified to the

counties and parishes as this Mortgage is recorded, (i) all persons other than
Mortgagor and its affiliates shall be entitled to rely on the releases,
waivers, consents, approvals, notifications and other acts (including, without
limitation, appointment of substitute or successor trustee, or trustees,
hereunder and the bidding in of all or any part of the secured indebtedness
held by any one or more Lenders, whether the same be conducted under the
provisions hereof or otherwise) of Administrative Agent, without inquiry into
any such agreements or the existence of required consent or approval of any
Lender and without the joinder of any party other than Administrative Agent in
such releases, waivers, consents, approvals, notifications or other acts and
(ii) all notices, requests, consents, demands and other communications required
or permitted to be given hereunder may be given to Administrative Agent.


 


Section 6.15           Waivers.  Subject to the Second Amended and Restated
Credit Agreement, Administrative Agent may at any time and from time to time in
writing waive compliance by Mortgagor with any covenant herein made by
Mortgagor to the extent and in the manner specified in such writing, or consent
to Mortgagor’s doing any act which hereunder Mortgagor is prohibited from
doing, or to Mortgagor’s failing to do any act which hereunder Mortgagor is
required to do, to the extent and in the manner specified in such writing, or
release any part of the Mortgaged Property or any interest therein or any
Production Proceeds from the lien and security interest of this Mortgage, without
the joinder of Trustee.  Any party
liable, either directly or indirectly, for the secured indebtedness or for any
covenant herein or in any other Loan Document may be released from all or any
part of such obligations without impairing or releasing the liability of any
other party.  No such act shall in any
way impair any rights or powers hereunder except to the extent specifically
agreed to in such writing.

Mortgagee and all other parties to any of the Loan Documents to contract in
strict compliance with applicable usury law from time to time in effect.  In furtherance thereof, it is stipulated and
agreed that none of the terms and provisions contained herein or in the other
Loan Documents shall ever be construed to create a contract to pay, for the
use, forbearance or detention of money, interest in excess of the maximum
amount of interest permitted to be collected, charged, taken, reserved, or
received by applicable law from time to time in effect.


 


Section 6.17           GOVERNING LAW.  This
Mortgage shall be governed by and construed in accordance with the laws of the
State of Texas, without giving effect to its laws relating to conflicts of
laws, except to the extent that the laws of any other jurisdiction mandatorily
govern the creation of, or the manner or procedure for enforcement of the lien
created by this Mortgage, provided that any rights or remedies herein provided
that shall be valid under the laws of the jurisdiction where proceedings for
the enforcement hereof shall be taken shall not be affected by the invalidity,
if any, of such rights or remedies under the laws of the State of Texas.

EXHIBIT A


 


TO


 


AMENDED AND RESTATED MORTGAGE, DEED OF TRUST,

ASSIGNMENT OF PRODUCTION, SECURITY AGREEMENT, 

FIXTURE FILING, AND FINANCING STATEMENT


 


This Exhibit A describes
the Hydrocarbon Property (as defined in the body of this instrument).  This Exhibit A also sets forth a list
of certain of the wells located on the Hydrocarbon Property, together with
Mortgagor’s representation as to the nature and quantum of Working Interest (as
defined below) and Net Revenue Interest (as defined below) owned by Mortgagor
with respect to those wells.


 


The designation “Working
Interest” or “WI” when used in this Exhibit A means the interest of Mortgagor
upon which is calculated Mortgagor’s proportionate share of the costs,
expenses, and liabilities attributable to the oil, gas, and mineral leases
described herein.  The designation “Net
Revenue Interest” or “NRI” or “NRIO” or “NRIG” when used in this Exhibit A
means the interest in the gross production of oil and gas and other minerals
from other properties subject to the oil, gas, and mineral leases to which
Mortgagor is entitled by virtue of its ownership of the Working Interest after
deducting all landowner royalties, overriding royalties, and similar interests
attributable to the Working Interest. 
The designation “Overriding Royalty Interest” “ORRI” means an interest
in production which is free of any obligation for the expense of exploration,
development, and production, bearing only its pro rata share of severance,
production, and other similar taxes and, in instances where the document
creating the overriding royalty interest so provides, costs associated with
compression, dehydration, other treating or processing, or transportation of
production of oil, gas, or other minerals relating to the marketing of such
production.  The designation “Royalty
Interest” or “RI” means an interest in production which results from an
ownership in the mineral fee estate or royalty estate in the relevant land and
which is free of any obligation for the expense of exploration, development,
and production, bearing only its pro rata share of severance,  production, ad valorem, and other similar
taxes and, in instances where the document creating the royalty interest so
provides, costs associated with compression, dehydration, other treating or
processing or transportation of production of oil, gas, or other minerals
relating to the marketing of such production. 
Each amount set forth as “Working Interest” or “WI” or “Net Revenue
Interest” or “NRI” or “NRIO” or “NRIG” is Mortgagor’s minimum interest after
giving full effect to, among other things, all Permitted Liens (as defined in
the Credit Agreement).


 


Any reference in this Exhibit
A to wells or units is for warranty of interest, administrative
convenience, and identification and shall not limit or restrict the right,
title, interest, or properties covered by this Deed of Trust.  All right, title, and interest of Mortgagor
in the properties described herein and in the Mortgaged Property (as defined in
the body of this instrument) is and shall be subject to this Mortgage,
regardless of the presence thereon of any interests, units, or wells not
described herein.


 


Unless otherwise expressly
provided, all recording references in this Exhibit A are references to
the official public records of real property in the county or counties (or
parish or parishes) in which the Mortgaged Property is located and in which
records documents relating to the Mortgaged Property are recorded, whether
Conveyance Records, Deed Records, Mortgage Records, Oil and Gas Records, Oil
and Gas Lease Records, or other records.

Pledge Agreement or for the execution, delivery, or performance of this Pledge
Agreement by Pledgor (except to the extent that financing statements are
required under the UCC to be filed in order to maintain a perfected security
interest) or (ii) for the exercise by Secured Party or any Lender of the voting
or other rights provided for in this Pledge Agreement or the remedies in
respect of the Pledged Collateral pursuant to this Pledge Agreement (except

(d)           Pledgor
has the full right, power and authority to deliver, pledge, assign and transfer
the Pledged Collateral to Secured Party.


 


(e)           [The
[Membership Interests][Partnership Interests] listed on the attached Schedule
II constitute [100][1]% of the issued and outstanding [membership][general partnership]
interests of the respective issuer thereof and all [Membership
Interests][Partnership Interests] in which Pledgor has any ownership
interest.][The Pledged Shares listed on the attached Schedule II constitute
100% of the issued and outstanding shares of capital stock of the respective
issuer thereof and of the Pledged Shares in which Pledgor has any ownership
interests.]


 


(f)            The
name of Pledgor set forth in the first paragraph of this Pledge Agreement is
the exact legal name of Pledgor.  The
legal address of Pledgor and the address of its principal place of business and

Section 4.               Pledgor’s
Covenants.  During the term of this
Pledge Agreement and until all of the Secured Obligations have been fully and finally
paid and discharged in full, Pledgor covenants and agrees with Secured Party
that:


 


(a)           Protect
Collateral; Further Assurances. 
Pledgor will warrant and defend the rights and title herein granted unto
Secured Party in and to the Pledged Collateral (and all right, title, and
interest represented by the Pledged Collateral) against the claims and demands
of all Persons whomsoever.  Pledgor
agrees that, at the expense of Pledgor, Pledgor will promptly execute and
deliver all further instruments and documents, and take all further action,
that may be reasonably necessary and that Secured Party or any Lender may
reasonably request, in order to perfect and protect any security interest
granted or purported to be granted hereby or to enable Secured Party or any
Lender to exercise and enforce its rights and remedies hereunder with respect
to any Pledged Collateral.


 


(b)           Transfer,
Other Liens, and Additional Shares. 
Pledgor agrees that it will not (i) sell or otherwise dispose of, or
grant any option with respect to, any of the Pledged Collateral or (ii) create
or permit to exist any Lien upon or with respect to any of the Pledged
Collateral, except for (A) the Liens and security interest under this Pledge
Agreement and (B) other Permitted Liens. 
Pledgor agrees that it will (1) cause each issuer of the Pledged
Collateral not to issue any other membership interests, partnership interests,
capital stock or other securities in addition to or in substitution for the
Pledged Collateral issued by such issuer, except to Pledgor and (2) pledge
hereunder, immediately upon its acquisition (directly or indirectly) thereof,
any additional membership interests, partnership interests, capital stock or
other securities of an issuer of the Pledged


 


5

















 


Collateral.  Pledgor shall not
approve any amendment or modification of any of the Pledged Collateral unless
it shall have given at least ten Business Days’ prior written notice (or such
lesser period as may be agreed by Secured Party in writing) to, and such
amendment or modification would not be materially adverse to the interests of
the Lenders.


 


(c)           Jurisdiction
of Formation; Name Change.  Pledgor
shall not (i) amend, supplement, modify or restate its articles or certificate
of incorporation, bylaws, limited liability company agreements, or other
equivalent organizational documents if such amendment, supplement, modification
or restatement would be materially adverse to the interests of the Lenders, or
(ii) unless the Pledgor shall have given Secured Party at least ten Business
Days’ prior written notice (or such lesser period as may be agreed by Secured
Party in writing), amend its name or change its jurisdiction of incorporation,
organization or formation.  Promptly
upon the request of Secured Party, Pledgor shall take all such action as
Secured Party shall reasonably request to maintain the security interest of
Secured Party in the Pledged Collateral granted hereby at all time fully
perfected and in full force and effect.


 


Section 5.               Remedies
upon Default.  If any Event of
Default shall have occurred and be continuing:


 


(a)           UCC
Remedies.  To the extent permitted
by law, Secured Party may exercise in respect of the Pledged Collateral, in
addition to other rights and remedies provided for in this Pledge Agreement or
otherwise available to it, all the rights and remedies of a secured party under
the UCC (whether or not the UCC applies to the affected Pledged
Collateral).  This Pledge Agreement shall
not be construed to authorize the Secured Party to take any action prohibited
by the UCC or to constitute a waiver by the Pledgor of any right that the UCC
does not permit the Pledgor to waive.


 


(b)           Dividends
and Other Rights.


 


(i)            All
rights of Pledgor to exercise the voting and other consensual rights which it
would otherwise be entitled to exercise pursuant to Section 2(d)(i) may be
exercised by Secured Party if Secured Party so elects and gives written notice
of such election to Pledgor and all rights of Pledgor to receive the dividends and
other distributions on or in respect of the Pledged Collateral and the proceeds
of sale of the Pledged Collateral which it would otherwise be authorized to
receive and retain pursuant to Section 2(d)(ii) shall cease at such time as
such written notice is deemed effective pursuant to the provisions of the
Credit Agreement related to effectiveness of notices.


 


(ii)           All
dividends and other distributions on or in respect of the Pledged Collateral
and the proceeds of sale of the Pledged Collateral that are thereafter received
by Pledgor shall be received in trust for the benefit of Secured Party, shall
be segregated from other funds of Pledgor, and shall be promptly paid over to
Secured Party as Pledged Collateral in the same form as so received (with any necessary
indorsement).


 


6

















 


(c)           Sale
of Pledged Collateral. Secured Party may sell all or part of the Pledged
Collateral at public or private sale, at any of Secured Party’s offices or
elsewhere, for cash, on credit, or for future delivery, and upon such other
terms as Secured Party may deem commercially reasonable in accordance with
applicable laws.  Pledgor agrees that to
the extent permitted by law such sales may be made without notice.  If notice is required by law, Pledgor hereby
deems 10 days’ advance notice of the time and place of any public sale or the
time after which any private sale is to be made reasonable notification,
recognizing that if the Pledged Collateral threatens to decline speedily in value
or is of a type customarily sold on a recognized market shorter notice may be
reasonable.  Secured Party shall not be
obligated to make any sale of the Pledged Collateral regardless of notice of
sale having been given.  Secured Party
may adjourn any public or private sale from time-to-time by announcement at the
time and place fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was so adjourned.  Pledgor shall cooperate fully with Secured
Party in all respects in selling or realizing upon all or any part of the
Pledged Collateral.  In addition,
Pledgor shall fully comply with the securities laws of the United States, the
State of [Delaware][Nevada], and other states and take such actions as may be
necessary to permit Secured Party to sell or otherwise dispose of any
securities representing the Pledged Collateral in compliance with such laws.


 


(d)           Exempt
Sale.  If, in the opinion of Secured
Party, there is any question that a public or semipublic sale or distribution
of any Pledged Collateral will violate any state or federal securities law,
Secured Party in its discretion (i) may offer and sell securities privately to
purchasers who will agree to take them for investment purposes and not with a
view to distribution and who will agree to imposition of restrictive legends on
the certificates representing the security, or (ii) may sell such securities in
an intrastate offering under Section 3(a)(11) of the Securities Act of 1933, as
amended, and no sale so made in good faith by Secured Party shall be deemed to
be not “commercially reasonable” solely because so made.  Pledgor shall cooperate fully with Secured
Party in all reasonable respects in selling or realizing upon all or any part
of the Pledged Collateral.


 


(e)           Application
of Collateral. The proceeds of any sale, or other realization upon all or
any part of the Collateral pledged by Pledgor shall be applied by Secured Party
as set forth in Section 7.06 of the Credit Agreement.


 


(f)            Cumulative
Remedies.  Each right, power and
remedy herein specifically granted to Secured Party or otherwise available to
it shall be cumulative, and shall be in addition to every other right, power
and remedy herein specifically given or now or hereafter existing at law, in
equity, or otherwise, and each such right, power and remedy, whether
specifically granted herein or otherwise existing, may be exercised at any time
and from time-to-time as often and in such order as may be deemed expedient by
Secured Party in its sole discretion. 
No failure on the part of Secured Party to exercise, and no delay in
exercising, and no course of dealing with respect to, any such right, power or
remedy, shall operate as a waiver thereof, nor shall any single or partial
exercise of any such rights, power or remedy preclude any other or further
exercise thereof or the exercise of any other right.


 


7

















 


Section 6.               Secured
Party as Attorney-in-Fact for Pledgor.


 


(a)           Secured
Party Appointed Attorney-in-Fact.  Pledgor
hereby irrevocably appoints Secured Party as Pledgor’s attorney-in-fact, with
full authority after the occurrence and during the continuance of an Event of
Default to act for Pledgor and in the name of Pledgor, and, in Secured Party’s
discretion, subject to Pledgor’s revocable rights specified in Section 2(d), to
take any action and to execute any instrument which Secured Party may deem
necessary or advisable to accomplish the purposes of this Pledge Agreement,
including, without limitation, to receive, indorse, and collect all instruments
made payable to Pledgor representing the proceeds of the sale of the Pledged
Collateral, or any distribution in respect of the Pledged Collateral and to
give full discharge for the same. 
Pledgor hereby acknowledges, consents and agrees that the power of
attorney granted pursuant to this Section is irrevocable and coupled with an
interest.


 


(b)           Secured
Party May Perform. Secured Party may from time-to-time, at its option and
expense, perform any act which Pledgor agrees hereunder to perform and which
Pledgor shall fail to perform after being requested in writing so to perform
(it being understood that no such request need be given after the occurrence
and during the continuance of any Event of Default and after notice thereof by
Secured Party to Pledgor) and Secured Party may from time-to-time take any
other action which Secured Party reasonably deems necessary for the
maintenance, preservation or protection of any of the Pledged Collateral or of
its security interest therein.  Secured
Party shall be obligated to provide notice to Pledgor of any action taken
hereunder by telecopy or by registered mail.


 


(c)           Secured
Party Has No Duty.  The powers
conferred on Secured Party hereunder are solely to protect its interest in the
Pledged Collateral and shall not impose any duty on it to exercise any such
powers.  Except for reasonable care of
any Pledged Collateral in its possession and the accounting for moneys actually
received by it hereunder, Secured Party shall have no duty as to any Pledged
Collateral or responsibility for taking any necessary steps to preserve rights
against prior parties or any other rights pertaining to any Pledged Collateral.


 


(d)           Reasonable
Care.  Secured Party shall be deemed
to have exercised reasonable care in the custody and preservation of the
Pledged Collateral in its possession if the Pledged Collateral is accorded
treatment substantially equal to that which Secured Party accords its own
property, it being understood that Secured Party shall have no responsibility
for (i) ascertaining or taking action with respect to calls, conversions,
exchanges, maturities, tenders, or other matters relative to any Pledged
Collateral, whether or not Secured Party has or is deemed to have knowledge of
such matters, or (ii) taking any necessary steps to preserve rights against any
parties with respect to any Pledged Collateral.


 


Section 7.               Miscellaneous.


 


(a)           Expenses.  Pledgor will upon demand pay to Secured
Party for its benefit and the benefit of the Lenders the amount of any
reasonable out-of-pocket expenses,


 


8

















 


including the reasonable fees and disbursements of its counsel and of
any experts, which Secured Party and the Lenders may incur in connection with
(i) the custody, preservation, use, or operation of, or the sale, collection,
or other realization of, any of the Pledged Collateral, (ii) the exercise or
enforcement of any of the rights of Secured Party or any Lender hereunder, and
(iii) the failure by Pledgor to perform or observe any of the provisions
hereof.


 


(b)           Amendments,
Etc.  No amendment or waiver of any
provision of this Pledge Agreement nor consent to any departure by Pledgor
herefrom shall be effective unless made in writing and authenticated by Pledgor
and Secured Party.  In addition, no such
amendment or waiver shall be effective unless given or entered into with the
necessary approvals of the Lenders as required in the Credit Agreement.  Any such waiver or consent, whether by
Secured Party or Secured Party and the Lenders shall be effective only in the
specific instance and for the specific purpose for which given.


 


(c)           Addresses
for Notices.  All notices and other
communications provided for hereunder shall be in the manner and to the
addresses set forth in the Credit Agreement.


 


(d)           Continuing
Security Interest; Transfer of Interest. 
This Pledge Agreement shall create a continuing security interest in the
Pledged Collateral and, unless expressly released by Secured Party, shall (i)
remain in full force and effect until payment in full and termination of the
Secured Obligations, (ii) be binding upon Pledgor, Secured Party, the Lenders
and their successors, and assigns, and (iii) inure, together with the rights
and remedies of Secured Party hereunder, to the benefit of and be binding upon,
Secured Party, the Lenders and their respective successors, transferees, and
assigns.  Upon the payment in full and
termination of the Secured Obligations, the security interest granted hereby
shall terminate and all rights to the Pledged Collateral shall revert to
Pledgor to the extent such Pledged Collateral shall not have been sold or
otherwise applied pursuant to the terms hereof.  Without limiting the generality of the foregoing clause, when any
Lender assigns or otherwise transfers any interest held by it under the Credit
Agreement or other Loan Document to any other Person pursuant to the terms of
the Credit Agreement or other Loan Document, that other Person shall thereupon
become vested with all the benefits held by such Lender under this Pledge
Agreement.  Upon any such termination,
Secured Party will, at Pledgor’s expense, deliver all Pledged Collateral to
Pledgor, execute and deliver to Pledgor such documents as Pledgor shall
reasonably request and take any other actions reasonably requested to evidence
or effect such termination.


 


(e)           Waivers.  Pledgor hereby waives:


 


(i)            promptness,
diligence, notice of acceptance, and any other notice with respect to any of
the Secured Obligations and this Pledge Agreement;


 


(ii)           any
requirement that Secured Party or any Lender protect, secure, perfect, or
insure any Lien or any Property subject thereto or exhaust any right or


 


9

















 


take any action against Pledgor, any other Guarantor, Borrower or any
other Person or any collateral; and


 


(iii)          any
duty on the part of Secured Party to disclose to Pledgor any matter, fact, or
thing relating to the business, operation, or condition of Pledgor, any other
Guarantor, Borrower and their respective assets now known or hereafter known by
such Person.


 


(f)            Severability.  Wherever possible each provision of this
Pledge Agreement shall be interpreted in such manner as to be effective and
valid under applicable law, but if any provision of this Pledge Agreement shall
be prohibited by or invalid under such law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Pledge Agreement.


 


(g)           Choice
of Law.  This Pledge Agreement shall
be governed by and construed and enforced in accordance with the laws of the
state of New York, except to the extent that the validity or perfection of the
security interests hereunder, or remedies hereunder, in respect of any
particular Collateral are governed by the laws of a jurisdiction other than the
state of New York.


 


(h)           Counterparts.  For the convenience of the parties, this
Pledge Agreement may be executed in multiple counterparts, each of which for
all purposes shall be deemed to be an original, and all such counterparts shall
together constitute but one and the same Pledge Agreement.


 


(i)            Reinstatement.  If, at any time after payment in full by
Pledgor of all Secured Obligations and termination of Secured Party’s security
interest, any payments on the Secured Obligations previously made by Pledgor or
any other person must be disgorged by Secured Party for any reason whatsoever,
including, without limitation, the insolvency, bankruptcy or reorganization of
Pledgor or such Person, this Pledge Agreement and Secured Party’s security
interests herein shall be reinstated as to all disgorged payments as though
such payments had not been made, and Pledgor shall sign and deliver to Secured
Party all documents, and shall do such other acts and things, as may be
necessary to reinstate and perfect Secured Party’s security interest.


 


(j)            Amendment
and Restatement.  This Pledge
Agreement amends and restates in its entirety the Existing Security Documents,
and all of the terms hereof shall supersede the terms and provisions
thereof.  This Pledge Agreement renews
and extends all Liens existing by virtue of the Existing Security Documents,
but the terms, provisions and conditions of such Liens shall hereafter be
governed in all respects by this Pledge Agreement.

A.            [Brigham Oil & Gas, L.P., a
Delaware limited partnership (“Borrower”)] [Grantor], the lenders party

B.            In order to secure the full and
punctual payment and performance of the obligations under the Existing Credit

executed and delivered the security instruments described on Schedule I
attached hereto (the “Existing Security Documents”) in favor of the
Existing Agent and has granted a continuing security interest in and to the
Collateral (as hereafter defined).


 


C.            The Secured Party has replaced the

2

Collateral; Liens.  Grantor is, and
will be the record and beneficial owner of all Collateral pledged by Grantor
free and clear of any Lien, except for Liens created hereby or other Permitted
Liens.  No effective financing statement
or other instrument similar in effect covering all or any part of the
Collateral is, or will be on file in any recording office, except such as may
be filed in connection with this Security Agreement or in connection with other
Permitted Liens or for which satisfactory releases have been received by
Secured Party.  The execution, delivery
and performance by Grantor of this Security Agreement and the grant of the

and have been duly authorized by all necessary governing action.


 


(b)           Authorization and
Approvals.  No consent, order,

the security interest in the Collateral granted by this Security Agreement,
(iii) the perfection of such security interest or (iv) the exercise by Secured
Party or any Lender of its rights and remedies under this Security Agreement
(except as may be required in connection with such disposition by laws
affecting the offering and sale of securities generally).


 


(c)           Lien Priority and
Perfection.  On the Closing Date
this Security Agreement will create valid and continuing security interests in
the Collateral, securing the payment of the Secured Obligations.  Upon the filing of financing statements in
the office(s) set forth on Schedule II attached hereto, the security interests
granted to Secured Party hereunder will constitute valid first-priority
perfected security interests in all Collateral with respect to which a security
interest can be perfected by the filing of a financing statement, subject only
to Permitted Liens.


 


(d)           Legal Name;
Address; Location of Records.  The

the exact legal name of Grantor.  The

business and chief executive office is 6300 Bridge Point Parkway, Building 2,
Suite 500, Austin, Texas 78730.  Grantor
keeps all records and documents relating to the Collateral at such address.

(a)           Further
Assurances.  Grantor agrees that at
any time, at Grantor’s expense, Grantor will promptly execute and deliver all
further instruments and documents, and take all further action, that may be
reasonably necessary or that Secured Party or any Lender may reasonably
request, in order to perfect and protect any security interest granted or
purported to be granted hereby or to enable Secured Party or any Lender to
exercise and enforce its rights and remedies hereunder with respect to any
Collateral.  Without limiting the
generality of the foregoing, Grantor will at Secured Party’s request:


 


3

















 


(i)            with respect to any
of the Collateral that is evidenced by a promissory note or other Instrument or
by Chattel Paper and if, in the case of any such instrument, its value exceeds
$100,000, deliver and pledge to the Administrative Agent such note, Instrument
or Chattel Paper, duly indorsed and accompanied by duly executed instruments of
transfer or assignment, all in form and substance satisfactory to the
Administrative Agent; and


 


(ii)           file (or authorize
the filing of) such financing or continuation statements, or amendments
thereto, and such other instruments or notices as may be reasonably necessary,
or as Secured Party may reasonably request, in order to perfect and preserve
the security interests granted or purported to be granted hereby.


 


(b)           Insurance.


 


(i)            Grantor shall, at
its own expense, maintain, or cause to be maintained, insurance with respect to
the Collateral owned by Grantor in such amounts, against such risks, in such
form, and with such insurers, as the Credit Agreement requires.  Further, Grantor shall deliver certificates
of insurance as the Credit Agreement requires.


 


(ii)           During the
continuance of any Event of Default, all loss casualty insurance payments in
respect to such Collateral shall be paid to and applied by Secured Party as
specified in the Credit Agreement.


 


(c)           Jurisdiction of
Formation; Name Change.  Grantor
shall not (i) amend, supplement, modify or restate its articles or certificate
of incorporation, bylaws, limited liability company agreements, or other
equivalent organizational documents if such amendment, supplement, modification
or restatement would be materially adverse to the interests of the Lenders, or
(ii) unless the Grantor shall have given Secured Party at least ten Business
Days’ prior written notice (or such lesser period as may be agreed by Secured
Party in writing), amend its name or change its jurisdiction of incorporation,
organization or formation.  Promptly
upon the request of Secured Party, Grantor shall take all such action as
Secured Party shall reasonably request to maintain the security interest of
Secured Party in the Collateral granted hereby at all time fully perfected and
in full force and effect.


 


(d)           Right of
Inspection.  Grantor will hold and
preserve, at its own cost and expense satisfactory and complete records of the
Collateral, including, but not limited to, Instruments, Documents, Chattel
Paper, contracts, and Records with respect to the Receivables.


 


(e)           Liability Under
Contracts and Receivables. 
Notwithstanding anything in this Security Agreement to the contrary,


 


(i)            the execution of
this Security Agreement shall not release Grantor from its obligations and
duties under the contracts and agreements and Receivables included in the
Collateral to the extent set forth therein,


 


4

















 


(ii)           the exercise by
Secured Party of any of its rights hereunder shall not release Grantor from any
of its duties or obligations under the contracts and agreements and the
Receivables included in the Collateral, and


 


(iii)          Secured Party shall
not have any obligation or liability under the contracts and agreements and the
Receivables included in the Collateral by reason of the execution and delivery
of this Security Agreement, nor shall Secured Party be obligated to perform any
of the obligations or duties of Grantor thereunder or to take any action to
collect or enforce any claim for payment assigned hereunder.


 


(f)            Transfer of
Certain Collateral; Release of Certain Security Interest.  Grantor agrees that it shall not sell,
assign, or otherwise dispose of any Collateral except as otherwise permitted
under the Credit Agreement.  Secured
Party shall promptly, at Grantor’s expense, execute and deliver all further
instruments and documents, and take all further action that Grantor may
reasonably request in order to release its security interest in any Collateral
that is disposed of in accordance with the terms of the Credit Agreement.


 


(g)           Receivables.  Grantor agrees that it will use commercially
reasonable efforts to ensure that each Receivable:


 


(i)            is and will be, in
all material respects, the genuine, legal, valid, and binding obligations of
the Account Debtor in respect thereof, representing an unsatisfied obligation
of such Account Debtor (except to the extent compromised or settled in the
ordinary course of business),


 


(ii)           is and will be, in
all material respects, enforceable in accordance with its terms, is not and
will not be subject to any setoffs, defenses, taxes, counterclaims, except in
the ordinary course of business,


 


(iii)          is and will be, in
all material respects, in compliance with all applicable Legal Requirements, whether
federal, state, local or foreign, and


 


(iv)          that if evidenced by
Chattel Paper, will not require the consent of the account debtor in respect
thereof in connection with its assignment hereunder.


 


Section 5.               Remedies.  If any Event of Default shall have occurred
and be continuing:


 


(a)           UCC Remedies.


 


(i)            To the extent
permitted by law, Secured Party may exercise in respect of the Collateral, in
addition to other rights and remedies provided for in this Security Agreement
or otherwise available to it, all the rights and remedies of a secured party
under the UCC (whether or not the UCC applies to the affected Collateral).  This Security Agreement shall not be
construed to authorize the Secured Party to take any action prohibited by the
UCC or to constitute a waiver by the Grantor of any right that the UCC does not
permit the Grantor to waive.


 


5

















 


(ii)           Upon written notice
to Grantor, all payments received by Grantor under or in connection with or in
respect of the Collateral shall be deposited with Secured Party.


 


(b)           Assembly of
Collateral.  Secured Party may, in
its reasonable discretion, require Grantor to, at Grantor’s expense, promptly
assemble all or part of the Collateral in such locations as Grantor and Secured
Party may agree at such time and that is reasonably convenient to both parties,
and make it available to Secured Party at such locations.  Secured Party may occupy any premises owned
or leased by Grantor where the Collateral or any part thereof is assembled for
a reasonable period in order to effectuate its rights and remedies hereunder or
under law, without obligation to Grantor in respect of such occupation.


 


(c)           Sale of
Collateral.  Secured Party may sell
all or part of the Collateral at a public or private sale, at any of Secured
Party’s offices or elsewhere, for cash, on credit, or for future delivery, and
upon such other terms as Secured Party may deem commercially reasonable.  Secured Party shall give Grantor 10 days
advance notice of the time and place of any public sale or the time after which
any private sale is to be made reasonable notification, recognizing that if the
Collateral is perishable or threatens to decline speedily in value or is of a
type customarily sold on a recognized market shorter notice may be
reasonable.  Secured Party shall not be
obligated to make any sale of Collateral regardless of notice of sale having
been given.  Secured Party may adjourn
any public or private sale from time to time by announcement at the time and
place fixed therefor, and such sale may, without further notice, be made at the
time and place to which it was so adjourned.


 


(d)           Contract Rights.  Secured Party may exercise any rights and
remedies of Grantor under or in connection with the Instruments, Documents,
Chattel Paper, or contracts which represent Receivables, the General
Intangibles, or otherwise relate to the Collateral, including, without
limitation, any rights of Grantor to demand or otherwise require payment of any
amount under, or performance of any provisions of, the Instruments, Documents,
Chattel Paper, or contracts which represent Receivables or the General
Intangibles.


 


(e)           Receivables.


 


(i)            Secured Party may,
or may direct Grantor to, take any action Secured Party deems necessary or
advisable to enforce collection of the Receivables including, without
limitation, notifying the Account Debtors or obligors under any Receivables of
the assignment of such Receivables to Secured Party and directing such Account
Debtors or obligors to make payment of all amounts due or to become due
directly to Secured Party.  Upon such
notification and direction, and at the expense of Grantor, Secured Party may
enforce collection of any such Receivables, and adjust, settle, or compromise
the amount or payment thereof in the same manner and to the same extent as
Grantor might have done.


 


6

















 


(ii)           After receipt by
Grantor of the notice referred to in subparagraph (i) above, all amounts and
Proceeds (including Instruments) received by Grantor in respect of the
Receivables shall be received in trust for the benefit of Secured Party
hereunder, shall be segregated from other funds of Grantor, and shall promptly
be paid over to Secured Party in the same form as so received (with any
necessary indorsement) to be held as Collateral.  Grantor shall not adjust, settle, or compromise the amount or
payment of any Receivable, or release wholly or partly any Account Debtor or
obligor thereof, or allow any credit or discount thereon other than in the
ordinary course of business and consistent with past practices.


 


Section 6.               Application of
Collateral.  The proceeds of any
sale, or other realization upon all or any part of the Collateral pledged by
Grantor shall be applied by Secured Party in the order set forth in Section
7.06 of the Credit Agreement.


 


Section 7.               Secured Party as
Attorney-in-Fact for Grantor.


 


(a)           Attorney-In-Fact.  Grantor hereby irrevocably appoints Secured
Party as Grantor’s attorney-in-fact, with full authority after the occurrence
and during the continuance of an Event of Default to act for Grantor and in the
name of Grantor to, in Secured Party’s discretion:


 


(i)            file one or more
financing or continuation statements, and amendments thereto, relative to all or
any part of the Collateral;


 


(ii)           to obtain and
adjust insurance as required pursuant to Section 5.02 of the Credit Agreement
to the extent Grantor has failed to provide such insurance;


 


(iii)          to receive,
indorse, and collect any drafts or other Instruments, Documents, and Chattel
Paper which are part of the Collateral pledged by Grantor;


 


(iv)          to take or cause to
be taken, all actions necessary to perform or comply or cause performance or
compliance with the terms of this Security Agreement, including, without
limitation, actions to pay or discharge taxes and Liens levied or placed on or
threatened against the Collateral;


 


(v)           to ask, demand,
collect, sue for, recover, compromise, receive, and give acquittance and
receipts for moneys due and to become due under or in respect of any of the
Collateral pledged by Grantor and to file any claims or take any action or
institute any proceedings which Secured Party may deem necessary or desirable
for the collection of any of such Collateral or otherwise to enforce the rights
of Secured Party with respect to any of such Collateral.


 


The power of
attorney granted hereby is coupled with an interest and is irrevocable.


 


7

















 


(b)           Secured Party May
Perform.  Secured Party may from
time-to-time, at its option and expense, perform any act which Grantor agrees
hereunder to perform and which Grantor shall fail to perform after being
requested in writing so to perform (it being understood that no such request
need be given after the occurrence and during the continuance of any Event of
Default) and Secured Party may from time-to-time take any other action which
Secured Party reasonably deems necessary for the maintenance, preservation or
protection of any of the Collateral or of its security interest therein.


 


(c)           Secured Party Has
No Duty.  The powers conferred on
Secured Party hereunder are solely to protect its interest in the Collateral
and shall not impose any duty on it to exercise any such powers.  Except for reasonable care of any Collateral
in its possession and the accounting for moneys actually received by it
hereunder, Secured Party shall have no duty as to any Collateral or
responsibility for taking any necessary steps to preserve rights against prior
parties or any other rights pertaining to any Collateral.


 


(d)           Reasonable Care.  Secured Party shall be deemed to have
exercised reasonable care in the custody and preservation of the Collateral in
its possession if the Collateral is accorded treatment substantially equal to
that which Secured Party accords its own Property, it being understood that
Secured Party shall have no responsibility for taking any necessary steps to
preserve rights against any parties with respect to any Collateral.


 


Section 8.               Miscellaneous.


 


(a)           Expenses.  Grantor will upon demand pay to Secured
Party for its benefit and the benefit of the Lenders the amount of any
reasonable out-of-pocket expenses, including the reasonable fees and
disbursements of its counsel and of any experts, which Secured Party and the
Lenders may incur in connection with:


 


(i)            the custody,
preservation, use, or operation of, or the sale, collection, or other
realization of, any of the Collateral,


 


(ii)           the exercise or
enforcement of any of the rights of Secured Party or any Lender hereunder, and


 


(iii)          the failure by
Grantor to perform or observe any of the provisions hereof.


 


(b)           Amendments; Etc.  No amendment or waiver of any provision of
this Security Agreement nor consent to any departure by Grantor herefrom shall
be effective unless made in writing and authenticated by Grantor and Secured
Party.  In addition, no such amendment
or waiver shall be effective unless given or entered into with the necessary
approvals of the Lenders as required in the Credit Agreement.  Any such waiver or consent, whether by
Secured Party or Secured Party and the Lenders shall be effective only in the
specific instance and for the specific purpose for which given.


 


8

















 


(c)           Addresses for
Notices.  All notices and other
communications provided for hereunder shall be made in the manner and to the
addresses set forth in the Credit Agreement.


 


(d)           Continuing
Security Interest; Transfer of Interest. 
This Security Agreement shall create a continuing security interest in
the Collateral and, unless expressly released by Secured Party, shall:


 


(i)            remain in full
force and effect until payment in full and termination of the Secured
Obligations,


 


(ii)           be binding upon
Grantor, Secured Party, the Lenders and their successors, and assigns, and


 


(iii)          inure, together
with the rights and remedies of Secured Party, hereunder, to the benefit of
Secured Party, the Lenders and their respective successors, transferees, and
assigns.


 


Upon the
payment in full and termination of the Secured Obligations, the security
interest granted hereby shall terminate and all rights to the Collateral
pledged by Grantor shall revert to Grantor to the extent such Collateral shall
not have been sold or otherwise applied pursuant to the terms hereof.  Without limiting the generality of the
foregoing clause, when any Lender assigns or otherwise transfers any interest
held by it under the Credit Agreement or other Loan Document to any other
Person pursuant to the terms of the Credit Agreement or other Loan Document,
that other Person shall thereupon become vested with all the benefits held by
such Lender under this Security Agreement. 
Upon any such termination, Secured Party will, at Grantor’s expense, execute
and deliver to Grantor such documents as Grantor shall reasonably request and
take any other actions reasonably requested to evidence or effect such
termination.


 


(e)           Severability.  Wherever possible each provision of this
Security Agreement shall be interpreted in such manner as to be effective and
valid under applicable law, but if any provision of this Security Agreement
shall be prohibited by or invalid under such law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of
this Security Agreement.


 


(f)            Choice of Law.  This Security Agreement shall be governed by
and construed and enforced in accordance with the laws of the state of New
York, except to the extent that the validity or perfection of the security
interests hereunder, or remedies hereunder, in respect of any particular
Collateral are governed by the laws of a jurisdiction other than the state of
New York.


 


(g)           Amendment and
Restatement.  This Security
Agreement amends and restates in its entirety the Existing Security Documents,
and all of the terms hereof shall supersede the terms and provisions
thereof.  This Security Agreement renews
and extends all Liens existing by virtue of the Existing Security Documents,
but the terms, provisions

and conditions
of such Liens shall hereafter be governed in all respects by this Security
Agreement.
