TERMS OF FACILITIES

2.1. Reducing Revolving Line of Credit.

2.1.1. During the Revolving Credit Period, and if no Default exists, each Lender severally agrees, subject to the other terms and conditions of this Agreement, to make Loans to the Borrower from time to time in amounts not to exceed, in the aggregate at any time outstanding, its Commitment. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans.

(i) Each Loan shall be made as part of an Advance consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no Lender shall be responsible for any other Lender's failure to make Loans as required.

(ii) Subject to the terms hereof, each Advance shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(iii) At the commencement of each Interest Period for any Eurodollar Advance, such Advance shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $25,000. At the time that each ABR Advance is made, such Advance shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $25,000; provided that an ABR Advance may be in an aggregate amount that is equal to the aggregate Unused Commitment of the Lenders. Advances of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of five (5) Eurodollar Advances outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Eurodollar Advance if the Interest Period requested with respect thereto would end after the Final Maturity Date.

2.1.2. No Lender shall be obligated to lend to the Borrower, and the Borrower shall not be entitled to borrow hereunder, any amount which would cause the outstanding principal amount of the Note held by such Lender to exceed its Commitment.

2.2. Method of Borrowing.

2.2.1. The Borrower shall give the Administrative Agent an irrevocable notice (a "Notice of Borrowing" or "Borrowing Notice" or "Borrowing Request"), in a form approved by the Administrative Agent and signed by the Borrower, not later than (a) in the case of a Eurodollar Advance, not later than 11:00 a.m., Houston time, three (3) Business Days before the date of such proposed Advance or (b) in the case of an ABR Borrowing, not later than 12:00 noon, Houston, Texas time, on the date of such proposed Advance. Each Notice of Borrowing shall specify:

(i) the Borrowing Date, which shall be a Business Day, of such requested Advance;

(ii) the aggregate amount of such requested Advance;

(iii) whether such Advance is to be an ABR Advance or a Eurodollar Advance; and

(iv) in the case of a Eurodollar Advance, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term "Interest Period".

If no election as to the Type of Advance is specified, then the requested Advance shall be an ABR Advance. If no Interest Period is specified with respect to any requested Eurodollar Advance, then the Borrower shall be deemed to have selected an Interest Period of one (1) month's duration. Each Notice of Borrowing shall constitute a representation by the Borrower that the amount of the requested Advance shall not cause the total principal of the Notes to exceed the Aggregate Commitment (i.e., the Borrowing Base then in effect).

2.2.2. Upon receipt of a Notice of Borrowing, the Administrative Agent shall promptly notify each Lender of the contents thereof and of such Lender's share of the requested Advance, and such Notice of Borrowing shall not thereafter be revocable by the Borrower.

2.2.3. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed Borrowing Date thereof by wire transfer of immediately available funds by 1:00 p.m., Houston, Texas time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained at the Administrative Agent. Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Advance that such Lender will not make available to the Administrative Agent such Lender's Percentage Share of such Advance, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.2.3 and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Advance available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender's Loan included in such Advance.

2.3. Interest Elections for Conversions and Continuations.

2.3.1. Each Advance initially shall be of the Type specified in the applicable Notice of Borrowing and, in the case of a Eurodollar Advance, shall have an initial Interest Period as specified in such Notice of Borrowing. Thereafter, the Borrower may elect to convert such Advance to a different Type or to continue such Advance and, in the case of a Eurodollar Advance, may elect Interest Periods therefor, all as provided in this Section 2.3. The Borrower may elect different options with respect to different portions of the affected Advance, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Advance, and the Loans comprising each such portion shall be considered a separate Advance.

2.3.2. To make an election pursuant to this Section 2.3, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Notice of Borrowing would be required under Section 2.2.1 if the Borrower were requesting an Advance of the Type resulting from such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

2.3.3. Each telephonic and written Interest Election Request shall specify the following information and be in compliance with Section 2.1:

(i) the Advance to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Advance (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Advance);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Advance is to be an ABR Advance or a Eurodollar Advance; and

(iv) if the resulting Advance is a Eurodollar Advance, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term "Interest Period".

If any such Interest Election Request requests a Eurodollar Advance but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one(1) month's duration.

2.3.4. Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender's portion of each resulting Advance.

2.3.5. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Advance prior to the end of the Interest Period applicable thereto, then, unless such Advance is repaid as provided herein, at the end of such Interest Period such Advance shall be converted to an ABR Advance. Notwithstanding any contrary provision hereof, if an Event of Default or a Borrowing Base Deficiency has occurred and is continuing: (i) no outstanding Advance may be converted to or continued as a Eurodollar Advance (and any Interest Election Request that requests the conversion of any Advance to, or continuation of any Advance as, a Eurodollar Advance shall be ineffective) and (ii) unless repaid, each Eurodollar Advance shall be converted to an ABR Advance at the end of the Interest Period applicable thereto.

2.4. Notes.

2.4.1. The Loans of each Lender shall be evidenced by a Note issued pursuant hereto by the Borrower, payable to the order of such Lender.

2.4.2. Upon receipt of each Lender's Note pursuant to Section 5.2.2, the Administrative Agent shall forward such Note to such Lender.

2.4.3. The outstanding principal balance of the Note of a Lender reflected by the notations (whether handwritten, electronic or otherwise) by such Lender on its records shall be deemed rebuttably presumptive evidence of the principal amount owing on its Note.

2.4.4. Each Lender may record the date, amount, Type, interest rate and, if applicable, Interest Period, amount of each payment of principal or interest made by the Borrower with respect thereto, and may, if such Lender so elects in connection with any transfer or enforcement of its Note, endorse on the schedule forming a part thereof appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that the failure of any Lender to make any such recordation or endorsement shall not affect the obligations of the Borrower hereunder or under the Notes. Each Lender is hereby irrevocably authorized by the Borrower so to endorse its Note and to attach to and make a part of its Note a continuation of any such schedule as and when required.

2.5. Certain Mandatory Payments and Prepayments of Principal. If at any time the aggregate principal of the Notes outstanding exceeds the Aggregate Commitment then in effect, the Borrower shall on the day of such occurrence, repay the principal of the Notes in an amount equal to such

excess, except that if the circumstances described in this Section are the direct result of a new determination of the Borrowing Base under Section 2.8.1, then the provisions of Section 2.8.3 shall apply.

2.6. Interest Rates.

2.6.1. Each Loan comprising an ABR Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such ABR Advance is made or is automatically converted from a Eurodollar Advance into an ABR Advance pursuant to Section 2.6.4, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.6.4, at a rate per annum equal to the lesser of (a) the Floating Rate or, if applicable, such higher rate as is specified in Section 3.3 or (b) the Highest Lawful Rate.

2.6.2. Each Loan comprising a Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period equal to the lesser of (a) the Adjusted LIBO Rate for the Interest Period in effect for such Advance or, if applicable, such higher rate as is specified in Section 3.3 or (b) the Highest Lawful Rate.

2.6.3. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and on the Final Maturity Date; provided that interest accrued pursuant to Section 3.3 shall be payable on demand.

2.6.4. If prior to the commencement of any Interest Period for a Eurodollar Advance:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or

(b) the Administrative Agent is advised by any Lender that the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lender of making or maintaining its or their Loans included in such Advance for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or electronic means as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Advance to, or continuation of any Advance as, a Eurodollar Advance shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Advance, such Advance shall be made as an ABR Advance.

2.6.5. Each change in the rate of interest charged hereunder shall become effective automatically and without notice to the Borrower upon the effective date of each change in the Floating Rate or the Highest Lawful Rate, as the case may be.

2.6.6. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to

borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market.

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

2.7. Unused Commitment Fees; Engineering Fees; Facility Fees; Authorized Payments by Lender.

2.7.1. The Borrower shall pay to the Administrative Agent, for the ratable benefit of the Lenders, a commitment fee of one-half of one percent (¹/2 of 1%) per annum, calculated daily on the actual number of days the Commitments are outstanding on the amount of the aggregate Unused Commitment of the Lenders in effect from time to time, such commitment fee to be payable quarterly as it accrues on January 1, 2005, and on each April 1, July 1, October 1 and January 1 occurring thereafter and upon termination of the Commitments.

2.7.2. The Borrower shall pay to the Collateral Agent on the Closing Date an engineering fee (an "Engineering Fee") in the amount of $3,500 exclusively for the account of the Collateral Agent and thereafter shall pay to the Collateral Agent exclusively for the account of the Collateral Agent an engineering fee in the amount of $3,000 (or $5,000 if the Borrowing Base exceeds or has ever exceeded $6,000,000) for each scheduled determination of the Borrowing Base or Borrower requested determination of the Borrowing Base, and $1,500 for each discretionary determination of the Borrowing Base. Notwithstanding the foregoing, if the internal engineers of the Collateral Agent are unable to perform the engineering review of the Properties of the Borrower, then the Borrower will pay the actual fees and expenses of any third-party engineers retained by the Collateral Agent to prepare an engineering report or perform an engineering review; provided, however, that in such event, the Borrower shall not be required to pay the Engineering Fee. All fees under this Section shall be payable at the time of each scheduled, discretionary or Borrower requested determination of the Borrowing Base referred to in Section 2.8.1 or at the time of a redetermination of the Borrowing Base required under Section 7.9.2.

2.7.3. To compensate for the costs of the extension of credit hereunder, the Borrower shall pay to the Administrative Agent, to be shared equally by the Administrative Agent and the Collateral Agent, (i) on the Closing Date, a facility fee in the amount of $27,500 and (ii) thereafter upon each determination of an increase in the Borrowing Base pursuant to Section 2.8.1, a facility fee in the amount of one percent (1.00%) of the amount by which the Borrowing Base is increased over that in effect on the date of such determination.

2.7.4. To compensate the Lenders for the cost of processing requests for waivers of and amendments to the provisions of this Agreement or the other Loan Documents, the Borrower shall pay to each Lender at the time of granting such waiver or entering into such amendment, the amount of $1,000 plus such additional amount as the Lenders and the Borrower shall specify or agree in such waiver or amendment.

2.7.5. The Lenders are irrevocably authorized to make Loans under the Notes for the payment of the fees and expenses of the Agents and the Lenders required to be paid by the Borrower hereunder, if such fees are not otherwise paid when due. The Administrative Agent shall pay over such Loan proceeds to itself or directly to such other Persons entitled to payment hereunder.

2.8. Determination of Borrowing Base; Automatic Reductions in Borrowing Base; Borrowing Base Deficiency; Notice of Redeterminations; Requests for Reductions in Borrowing Base.

2.8.1. On the basis of the information furnished to the Collateral Agent hereunder and such other reports, appraisals and information as the Collateral Agent may reasonably deem appropriate, the Collateral Agent, in consultation with the other Lenders, shall determine a new Borrowing Base quarterly as of January 1, 2005, April 1, 2005, July 1, 2005, and October 1, 2005, and each January 1 and July 1 occurring after October 1, 2005, prior to the Final Maturity Date or at any time it may elect if a Default has occurred which is continuing (the "scheduled determinations"), or at such other or additional times prior to the Final Maturity Date as the Administrative Agent or the Collateral Agent in their reasonable discretion may elect (the "discretionary determinations"), and the Collateral Agent, in consultation with the other Lenders, shall determine a new Borrowing Base at such additional times, but no more often than one (1) time in any 12-month period without the Collateral Agent's consent, as the Borrower may request (the "Borrower requested determinations"). Such determinations, if made, shall be in accordance with the customary practices and standards of the Collateral Agent for loans of a similar nature as in effect at the time such determinations are made (except that the Collateral Agent will make such downward adjustments to such determinations as are required by any Lender based on the practices and standards of such Lender) and shall be conclusive as to the Borrower, and any increases in the Borrowing Base must be approved by all of the Lenders and shall be subject to each Lender's complete credit approval process. The Borrowing Base resulting from the foregoing process will be the highest Borrowing Base which is acceptable to all of the Lenders. There is no duty, implied or explicit, on the Lenders to ever increase the Borrowing Base.

2.8.2. The Borrowing Base shall be automatically reduced as of the 1st day of each month, commencing January 1, 2006, and continuing on the first day of each month thereafter until the Final Maturity Date. Such reductions in the Borrowing Base each month shall be in the amount of $0.00 per month unless redetermined as herein permitted. At the time of each new Borrowing Base determination under Section 2.8.1, the Required Lenders in accordance with the customary standards and practices of each such Lender, may increase the amount of such monthly reductions, and the Required Lenders may decrease the amount of such monthly reductions, but the monthly Borrowing Base reductions under this Section 2.8.2 shall be $0.00 prior to January 1, 2006. There is no duty, implied or explicit, on the Lenders to ever decrease the amount of the monthly Borrowing Base reduction amounts.

2.8.3. Upon the occurrence of a Borrowing Base Deficiency, the Borrower shall, within thirty (30) days following notice by the Administrative Agent of the existence of such Borrowing Base Deficiency, do any one or more of the following in an aggregate amount at least equal to such Borrowing Base Deficiency: (i) make a prepayment of principal of the Notes or (ii) cause to be created first and prior perfected Liens (subject only to Permitted Liens) in favor of the Collateral Agent for the benefit of the Lenders, by instruments satisfactory to the Collateral Agent, on producing Oil and Gas Properties which in the opinion of each Lender would increase the Borrowing Base by an amount sufficient, in combination with clause (i) preceding, to eliminate such Borrowing Base Deficiency.

2.8.4. Upon each redetermination of the Borrowing Base, the Administrative Agent will notify the Borrower of such determination (which notice may be orally communicated to the Borrower and confirmed promptly thereafter in writing if the Borrowing Base is being decreased or the monthly Borrowing Base reduction amount is being increased), and the Borrowing Base and the amount by which the Borrowing Base shall be reduced so communicated to the Borrower shall become effective immediately upon such notification (regardless of any Notice of Borrowing the Administrative Agent might have received) and shall remain in effect until the next subsequent redetermination of the Borrowing Base.

2.8.5. The Borrower may at any time by written notice to the Administrative Agent request that the Borrowing Base be reduced (with no right of reinstatement) by an amount specified by the Borrower in such reduction notice, and the Borrowing Base shall be deemed so reduced upon receipt by the Administrative Agent of such reduction notice. Further, in the event the Borrower is advised of

any increase in the Borrowing Base, the Borrower may decline to utilize the increased borrowing availability created thereby and by written notice to the Administrative Agent irrevocably refuse to accept all or a portion of such increase, but any such refusal notice received by the Administrative Agent more than three (3) Business Days following such increase in the Borrowing Base shall be treated as a Borrowing Base reduction notice under the immediately preceding sentence.

2.9. Termination of Commitments; Maturity of Loans; Right of Borrower to Cancel Commitments.

2.9.1. The Commitment of each Lender shall terminate on the Final Maturity Date, unless terminated earlier in accordance with the terms hereof. If at any time the Aggregate Commitment or the Borrowing Base is terminated or reduced to zero, then the Commitments shall terminate on the effective date of such termination or reduction.

2.9.2. The Notes shall finally mature no later than the Final Maturity Date and any unpaid principal of the Notes and accrued, unpaid interest thereon shall be due and payable on such date.

2.9.3. The Borrower shall have the right upon payment in full of the Obligations to cancel in full (but not in part) the Aggregate Commitment, with no right of reinstatement.

ARTICLE III

GENERAL PROVISIONS

3.1. General Provisions as to Payments and Loans.

3.1.1. All payments of principal and interest on the Notes and of fees hereunder shall be made, without setoff, deduction or counterclaim, by 12:00 noon (Houston, Texas time) on the date such payments are due in federal or other funds immediately available at the principal office of the Administrative Agent referred to in Article XIII and, if not made by such time or in immediately available funds, then such payment shall be deemed made when such funds are available to the Administrative Agent for its full and unrestricted use. Each payment delivered to the Administrative Agent for the account of any Lender shall be delivered promptly by the Administrative Agent to such Lender in the same type of funds that the Administrative Agent received at such Lender's address specified pursuant to Article XIII. Except as otherwise provided herein, whenever any payment of principal of or interest on the Notes or of fees hereunder shall be due on a day which is not a Business Day, the date for payment thereof shall be extended to the next succeeding Business Day. If the date for any payment is extended by operation of law or otherwise, interest thereon shall be payable for such extended time. The Administrative Agent is hereby authorized upon notice to the Borrower to charge the account of the Borrower maintained with the Administrative Agent, for each payment of principal, interest and fees if not otherwise paid by the Borrower when it becomes due hereunder.

3.1.2. All payments made by the Borrower on the Notes shall be made free and clear of, and without reduction by reason of, any Taxes.

3.1.3. All requests for Advances shall be made on a Business Day.

3.1.4. All Loans shall be made available to the Borrower on a Business Day at the Administrative Agent's address referred to in Article XIII.

3.1.5. All payments and fundings shall be denominated in United States of America dollars.

3.2. Computation of Interest. Each determination hereunder of interest on the Note and fees hereunder based on per annum calculations shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day), subject to the limitations of the Highest Lawful Rate. The Floating Rate, Federal Funds Effective Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto.

3.3. Default Interest. The principal of the Notes shall bear interest at the Default Rate during any time an Event of Default exists and, to the extent permitted by law, overdue interest on the Notes shall bear interest at the Default Rate.

3.4. Prepayments Permitted.

3.4.1. The principal of the Notes and accrued interest thereon may be prepaid by the Borrower in whole or in part at any time and, except with respect to Eurodollar Advances, shall be without premium or penalty. Each prepayment of Advances pursuant to this Section shall be applied, first, ratably to any ABR Advances then outstanding, and, second, to any Eurodollar Advances then outstanding, and if more than one Eurodollar Advance is then outstanding, to each such Eurodollar Advance in order of priority beginning with the Eurodollar Advance with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Advance with the most number of days remaining in the Interest Period applicable thereto. Prepayments of Advances shall be accompanied by accrued interest to the date of prepayment. In the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

3.5. Limitation Period. Notwithstanding anything herein or in the Notes to the contrary, during any Limitation Period, the interest rate to be charged on amounts evidenced by the Notes shall be the Highest Lawful Rate, and the obligation, if any, of the Borrower for the payment of fees or other charges deemed to be interest under applicable law shall be suspended. During any period or periods of time following a Limitation Period, to the extent permitted by applicable laws of the State of Texas or the United States of America, the interest rate to be charged hereunder shall remain at the Highest Lawful Rate until such time as there has been paid to the Lenders (i) the amount of interest in excess of that accruing at the Highest Lawful Rate that the Lenders would have received during the Limitation Period had the interest rate remained at the otherwise applicable rate, and (ii) the amount of all interest and fees otherwise payable to the Lenders but for the effect of such Limitation Period.

3.6. Telephonic Notices.

3.6.1. The Borrower hereby authorizes the Administrative Agent to extend Advances, and to transfer funds, and hereby authorizes the Lenders to make Loans, based on telephonic, e-mail or other electronic notices made by any Person which the Administrative Agent or any Lender in good faith believes to be acting on behalf of the Borrower. The Borrower agrees to deliver promptly to the Administrative Agent a written confirmation, if such confirmation is requested by the Administrative Agent or any Lender, of each telephonic, e-mail or other electronic notices, signed by a Responsible Representative. If the written confirmation differs in any material respect from the action taken by the Administrative Agent and the Lenders, the records of the Administrative Agent and the Lenders shall be prima facie, but not conclusive, evidence of the matter notwithstanding anything to the contrary in such confirmation.

3.6.2. The Administrative Agent will promptly notify each Lender of the contents of each Notice of Borrowing and Borrowing Base reduction notice received by it hereunder. The Administrative Agent will give each Lender and the Borrower prompt notice of each change in the interest rate applicable to the Loans.

3.6.3. Each Lender may book its Loans at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation, and the Note payable to such Lender shall be deemed held by each Lender for the benefit of its Lending Installation. Each Lender may, by written or facsimile notice to the Administrative Agent and the Borrower, designate, or change any previous designation of, the Lending Installation through which Loans will be made by it and for whose account Note payments are to be made.

3.6.4. Unless the Borrower or a Lender, as the case may be, notifies the Administrative Agent prior to the date on which it is scheduled to make payment to the Administrative Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal, interest or fees to the Administrative Agent for the account of the Lenders, that it does not intend to make such payment, the Administrative Agent may assume that such payment has been made. The Administrative Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Administrative Agent, the recipient of such payment shall, on demand by the Administrative Agent, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent until the date the Administrative Agent recovers such amount at a rate per annum equal to (A) in the case of payment by a Lender, the Federal Funds Effective Rate for such day or (B) in the case of payment by the Borrower, the interest rate applicable to the Notes.

3.7. Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender's obligation to make such Eurodollar Loans shall be suspended (the "Affected Loans") until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender's Affected Loans shall be applied instead to its ABR Loans.

ARTICLE IV

Notwithstanding the foregoing provisions of this definition, Cash Taxes as of September 30, 2004, shall be calculated as Cash Taxes for the two-quarter period ending on such date multiplied by two(2); Cash Taxes as of December 31, 2004, shall be calculated as Cash Taxes for the three-quarter period ending on such date multiplied by four(4) and divided by three(3).

"EBITDAX" means, as of the last day of any fiscal quarter of the Borrower, the pre-tax net income of the Borrower and its Consolidated Subsidiaries for the four consecutive fiscal quarters ending on such last day plus (without duplication and only to the extent deducted in determining such net income), interest expense of the Borrower paid on the Notes for such period, intangible drilling expenses, depreciation, non-cash amortization, depletion, write-down of Oil and Gas Properties and other non-cash expenses of the Borrower and its Consolidated Subsidiaries for such period less gains on sales of assets and other non-cash income for such period included in the determination of net income of the Borrower and its Consolidated Subsidiaries plus losses on sales of assets and other non-cash losses for such period included in the determination of net income of the Borrower and its Consolidated Subsidiaries and, for the purposes of Section 7.15.3 only, less dividends and distributions paid or made by the Borrower during such period. Notwithstanding the foregoing provisions of this definition, EBITDAX as of September 30, 2004, shall be calculated as EBITDAX for the two-quarter period ending on such date multiplied by two(2); EBITDAX as of December 31, 2004, shall be calculated as EBITDAX for the three-quarter period ending on such date multiplied by four(4) and divided by three(3).

"Fixed Charges" means as of the last day of any fiscal quarter of the Borrower, the actual principal and cash interest payments on the Funded Debt of the Borrower and its Consolidated Subsidiaries during the four(4) consecutive fiscal quarters ending on such last day other than for the Notes plus required principal and cash interest payments on the Notes during the four(4) consecutive fiscal quarters ending on such last day. Notwithstanding the foregoing provisions of this definition, Fixed Charges as of September 30, 2004, shall be calculated as Fixed Charges for the two-quarter period ending on such date multiplied by two(2); Fixed Charges as of December 31, 2004, shall be calculated as Fixed Charges for the three-quarter period ending on such date multiplied by four(4) and divided by three(3).

7.15.2. Current Ratio. The Borrower will not permit the ratio of its Current Assets to its Current Liabilities to be less than 1.00 to 1.00, determined as of the end of each fiscal quarter of the Borrower ending on or after December 31, 2004.

"Current Assets" means the current assets of the Borrower and its Consolidated Subsidiaries plus the Unused Commitment.

"Current Liabilities" means the current liabilities of the Borrower and its Consolidated Subsidiaries, exclusive of the current portion of the Notes.

Notwithstanding the foregoing, during such times that the Borrower is required to deliver financial information to the Lenders in accordance with generally accepted accounting principles, neither Current Assets nor Current Liabilities shall include the amount of or any liabilities respecting any non-cash items as a result of the application of Financial Accounting Standards Board Statement Nos. 133, 137, 138 and any subsequent amendments thereto or the fair value of any Hedging Agreement or any non-hedge derivative contract (whether deemed effective or non-effective).

"EBITDAX" has the meaning given such term in Section 7.15.1.

"Funded Debt" as of the last day of any fiscal quarter of the Borrower, means Debt of the Borrower and its Consolidated Subsidiaries as of such last day described in clauses (i), (ii) or (iv) of the definition of Debt (other than Permitted Subordinated Indebtedness) and any other obligation for borrowed money or other financial accommodations which in accordance with GAAP would be shown as a liability on the balance sheet of the Borrower and its Consolidated Subsidiaries; any repurchase

For the avoidance of doubt, the term "Funded Debt" does not include the obligations of the Borrower under the Series A Preferred Stock.

7.16. Tax Shelter. In the event the Borrower determines to take any action inconsistent with the representation in Section 6.9.2, it will promptly notify the Administrative Agent thereof. Accordingly, if the Borrower so notifies the Administrative Agent, the Borrower acknowledges that the Administrative Agent and the Lenders may treat the Loans as part of a transaction that is subject to Treasury Regulation Section 301.6112-1, and the Administrative Agent and the Lenders will maintain the lists and other records required by such Treasury Regulation.

7.17.4. The Borrower shall furnish to the Administrative Agent, promptly upon the request of the Administrative Agent, such additional financial or other information concerning the assets, liabilities, operations, and transactions of the Borrower as the Administrative Agent may from time to time reasonably request.

MISCELLANEOUS

9.1. Amendments and Waivers. Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Lenders (and, if the rights or duties of the Administrative Agent or the Collateral Agent are affected thereby, by such Agent); provided that no such amendment or waiver shall, unless signed by all the Lenders, (i) increase or decrease the Commitments of any Lender (except for a ratable decrease in the Commitments of all Lenders) or subject any Lender to any additional obligation, (ii) reduce the principal of or rate of interest on any Note, or any fees hereunder, (iii) postpone the date fixed for any payment of principal of or interest on any Note, or any fees hereunder or (iv) postpone the scheduled termination of any Commitment, (v) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Notes, or the number of Lenders, which shall be required for the Lenders or any of them to take any action under this Section or any other provision of this Agreement, (vi) amend this Section 9.1 or (vii) effect a release of Collateral other than to facilitate the provisions of Section 7.9.2.

In determining whether the interest paid or payable, under any specific contingency, exceeds the Highest Lawful Rate in effect from day to day, the Borrower and the Lenders shall, to the maximum extent permitted under applicable law, (i) characterize any nonprincipal payment as an expense, fee, or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the Loans so that the interest rate is uniform throughout the entire term of the Loans; provided that, if the interest received by the Lenders for the actual period of existence thereof exceeds the Highest Lawful Rate in effect from day to day, the Lenders shall apply or refund to the Borrower the amount of such excess as provided in this Section, and, in such event, the Lenders shall not be subject to any penalties provided by any laws for contracting for, charging, taking, reserving, or receiving interest in excess of the Highest Lawful Rate in effect from day to day.

If on or after the date hereof, in the case of any Loan or any obligation to make Loans, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Lending Installation) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall impose, modify or deem applicable any reserve (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (or its Lending Installation) and the result of any of the foregoing is to reduce the amount of any sum received or receivable by such Lender (or its Lending Installation) under this Agreement or under its Notes with respect thereto, by an amount reasonably deemed by such Lender to be material, then, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction.

9.14.2. If any Lender shall have reasonably determined that, after the date hereof, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any such rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on capital of such Lender as a consequence of such Lender's obligations hereunder to a level below that which such Lender could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction.

9.14.3. Each Lender will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section and will designate a different Lending Installation if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Lender, be otherwise disadvantageous to such Lender. A certificate of any Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

9.15. Taxes.

9.15.1. For the purpose of Section 9.15, the following terms have the following meanings:

"Taxes" means any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings with respect to any payment by the Borrower pursuant to this Agreement or under any Note, and all penalties and interest with respect thereto, excluding (i) in the case of each Lender and the Administrative Agent, taxes imposed on its income, and franchise or similar taxes imposed on it, by a jurisdiction under the laws of which such Lender or the Administrative Agent (as the case may be) is organized or in which its principal executive office is located, in which its Lending Installation is located or in which it would be subject to tax due to some connection other than that created by this Agreement and (ii) in the case of each Lender, any United States withholding tax at the time such Lender first becomes a party to this Agreement.

"Other Taxes" means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or levies and all penalties and interest with respect thereto, which arise from the making of any payment pursuant to this Agreement or under any Note or from the execution or delivery of this Agreement or any Note.

9.15.2. Any and all payments by the Borrower to or for the account of any Lender or the Administrative Agent hereunder or under any Note shall be made without deduction for any Taxes or Other Taxes; provided that, if the Borrower shall be required by law to deduct any Taxes or Other Taxes from any such payments, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under Section 9.13) such 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, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Borrower shall furnish to the Administrative Agent the original or a certified copy of a receipt evidencing payment thereof.

9.15.3. The Borrower agrees to indemnify each Lender and the Administrative Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes on amounts payable under this Section) paid by such Lender or the Administrative Agent (as the case may be). This indemnification shall be paid within 15 days after such Lender or the Administrative Agent (as the case may be) makes appropriate demand therefor.

9.15.4. At least five Business Days prior to the first date on which interest or fees are payable hereunder for the account of any Lender, each Lender that is not incorporated under the laws of the United States of America, or a state thereof, agrees that it will deliver to each of the Borrower and the Administrative Agent two duly completed copies of United States Internal Revenue Service Form W-8 BEN or W-8 ECI or W-8 IMY or W-8 EXP or such other form as may be applicable and allowable under the Internal Revenue Code and the regulations thereunder (collectively, a "Withholding Form"), certifying in either case that such Lender is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes. Each Lender which so delivers a Withholding Form further undertakes to deliver to each of the Borrower and the Administrative Agent two additional copies of such form (or a successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent Withholding Form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Borrower or the Administrative Agent, in each case certifying that such Lender is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such Withholding Forms inapplicable or which would prevent such Lender from duly completing and delivering any such Withholding 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.

9.15.5. For any period with respect to which a Lender has failed to provide the Borrower or the Administrative Agent with the appropriate form pursuant to Section 9.15.4 (unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which such form originally was required to be provided which renders all such Withholding Forms inapplicable or which would prevent such Lender from duly completing and delivering any such Withholding Form with respect to it), such Lender shall not be entitled to indemnification under Section 9.15.2 or 9.15.3 with respect to Taxes imposed by the United States; provided that if 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 deliver a form required hereunder, the Borrower shall take such steps (at the expense of such Lender) as such Lender shall reasonably request to assist such Lender to recover such Taxes.

9.15.6. If the Borrower is required to pay additional amounts to or for the account of any Lender pursuant to Section 9.15, then such Lender will change the jurisdiction of its Lending Installation if, in the judgment of such Lender, such change (i) will eliminate or reduce any such additional payment which may thereafter accrue and (ii) is not otherwise disadvantageous to such Lender in its sole judgment.

Upon any such resignation, the remaining Lenders by majority in interest shall have the right to appoint, with the approval of the Borrower if no default then exists hereunder, which approval will not be unreasonably withheld or delayed, on behalf of the Borrower and the Lenders, a successor Agent.

10.12. Applicable Parties. The provisions of this Article are solely for the benefit of the Agents and the Lenders, and, except with respect to the appointment of a successor Agent, the Borrower shall not have any rights as a third party beneficiary or otherwise under any of the provisions of this Article. In performing functions and duties hereunder and under the other Loan Documents, each of the Agents shall act solely as the contractual agent of the Lenders and does not assume, nor shall either of them be deemed to have assumed, any obligation or relationship of trust or agency with or for the Borrower or any legal representative, successor, and assign of the Borrower.

ARTICLE XI

SETOFF; RATABLE TREATMENTS

11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if any Event of Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate thereof to or for the credit or account of the Borrower may be offset and applied toward the payment of the Obligations, whether or not the Obligations, or

any part hereof, shall then be due. Each Lender or Affiliate thereof making such an offset and application shall give the Borrower and the other Lenders written notice of such offset and application promptly after effecting it.

11.2. Ratable Treatments; Adjustments.

(a) Except to the extent otherwise expressly provided herein, (i) each Advance pursuant to this Agreement shall be made from the Lenders pro rata in accordance with their respective Commitments, (ii) each payment by the Borrower of fees shall be made for the account of the Lenders pro rata in accordance with their Percentage Shares, (iii) each payment of principal of Loans shall be made for the account of the Lenders pro rata in accordance with the principal balances of their respective Notes, and (iv) each payment of interest on the Notes shall be made for the account of the Lenders pro rata in accordance with their respective shares of the aggregate amount of interest due and payable to the Lenders under the Notes.

(b) The Administrative Agent shall distribute all payments with respect to the Obligations to the Lenders promptly upon receipt in like funds as received. In the event that any payments made hereunder by the Borrower at any particular time are insufficient to satisfy in full the Obligations due and payable at such time, such payments shall be applied (i) first, to fees and expenses due pursuant to the terms of this Agreement or any other Loan Document, (ii) second, to accrued interest, (iii) third, to the principal of the Notes, and (iv) last, to any other Obligations.

(c) If any Lender (for purposes of this Section, a "Benefitted Lender") shall at any time receive any payment of all or part of its portion of the Obligations, or receive any Collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8.1.4 or Section 8.1.5, or otherwise) in an amount greater than such Lender was entitled to receive pursuant to the terms hereof, such Benefitted Lender shall purchase for cash from the other Lenders such portion of the Obligations of such other Lenders, or shall provide such other Lenders with the benefits of any such Collateral or the proceeds thereof, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such Collateral or proceeds with each of the Lenders according to the terms hereof. If all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded and the purchase price and benefits returned by such Lender, to the extent of such recovery, but without interest. The Borrower agrees that each such Lender so purchasing a portion of the Obligations of another Lender may exercise all rights of payment (including rights of set-off) with respect to such portion as fully as if such Lender were the direct holder of such portion. If any Lender ever receives, by voluntary payment, exercise of rights of set-off or banker's lien, counterclaim, cross-action or otherwise, any funds of the Borrower to be applied to the Obligations, or receives any proceeds by realization on or with respect to any Collateral, all such funds and proceeds shall be forwarded immediately to the Administrative Agent for distribution in accordance with the terms of this Agreement.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1. Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors and assigns, except that (i) the Borrower shall not have any right to assign its rights or obligations under the Loan Documents and (ii) any assignment by any Lender must be made in compliance with Section 12.3. Notwithstanding clause (ii) of this Section 12.1, any Lender may at any time, without the consent of the Borrower or the Administrative Agent, assign all or any portion of its rights under this Agreement and its Note to a Federal Reserve Bank; provided, however, that no such assignment shall release the transferor Lender from its obligations hereunder. The Administrative Agent may treat the

payee of any Note as the owner thereof for all purposes hereof unless and until such payee complies with Section 12.3 in the case of an assignment thereof or, in the case of any other transfer, a written notice of the transfer is filed with the Administrative Agent. Any assignee or transferee of a Note agrees by acceptance thereof to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the holder of any Note, shall be conclusive and binding on any subsequent holder, transferee or assignee of such Note or of any Note or Notes issued in exchange therefor.

12.2. Participations; Voting Rights; Setoffs by Participants.

12.2.1. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other entities ("Participants") participating interests in any Loan owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender's obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the holder of any such Note for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under the Loan Documents.

12.2.2. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest which forgives principal, interest or fees or reduces the interest rate or fees payable with respect to any such Loan or Commitment, postpones any date fixed for any regularly-scheduled payment of principal of, or interest or fees on, any such Loan or Commitment, releases any guarantor of any such Loan or releases any substantial portion of Collateral, if any, securing any such Loan.

12.2.3. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, and each Lender shall retain the right of setoff provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender.

12.3. Assignments; Effective Date.

12.3.1. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more banks or other entities ("Purchasers") all or any part of its rights and obligations under the Loan Documents by completing and executing an Assignment and Assumption. The consent of the Borrower and the Administrative Agent, which consents shall not be unreasonably withheld or delayed, shall be required prior to an assignment becoming effective with respect to a Purchaser which is not a Lender or an Affiliate of a Lender; except that, if a Default has occurred and is continuing, the consent of the Borrower shall not be required. Each such assignment shall (unless it is to a Lender or an Affiliate thereof, or each of the Borrower and the Administrative Agent otherwise consents) be in an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining amount of the assigning Lender's Commitment (calculated as at the date of such assignment).

12.3.2. Upon (i) execution of such Assignment and Assumption by the Administrative Agent or, in circumstances where the consent of the Administrative Agent is not required, the delivery to the Administrative Agent of the Assignment and Assumption, fully completed and executed, and (ii) payment by the assigning Lender of a $3,500 processing fee to the Administrative Agent for its sole account for processing such Assignment and Assumption, such Assignment and Assumption shall become effective on the effective date specified in such Assignment and Assumption. The Assignment and Assumption shall contain a representation by the Purchaser to the effect that none of the consideration used to purchase of the Commitment and Loans under the applicable Assignment and Assumption are "plan assets" as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be "plan assets" under ERISA. On and after the effective date of such Assignment and Assumption, such Purchaser shall for all purposes be a Lender party to this Credit Agreement and any other Loan Document executed by the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Borrower, the Lenders or the Administrative Agent shall be required to release the transferor Lender with respect to the percentage of the Aggregate Commitment and Loans assigned to such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3.2, the transferor Lender, the Administrative Agent and the Borrower shall make appropriate arrangements so that replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser reflecting such assignment.

12.4. Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a "Transferee") and any prospective Transferee any and all information in such Lender's possession concerning the creditworthiness of the Borrower and the Subsidiaries.

12.5. Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 9.15.4.

12.6. Disclosure of Information. Notwithstanding any of the other provisions of this Agreement or the other Loan Documents, the Administrative Agent and each Lender (and each employee, representative, or other agent of the Administrative Agent and each such Lender) may disclose to any and all Persons, without limitation of any kind, the "tax treatment" and "tax structure" (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or the Lenders relating to such tax treatment and tax structure; provided that, with respect to any document or similar item that in either case contains information concerning the tax treatment or tax structure of the transaction as well as other information, this authorization shall only apply to such portions of the document or similar item that relate to the tax treatment or tax structure of the Loans and transactions contemplated hereby.

COUNTERPARTS

WHEREAS, the Administrative Agent, the Collateral Agent and the Lenders are herein sometimes collectively referred to as the "Guaranteed Parties"; and

WHEREAS, it is a condition precedent to the obligation of the Lenders to permit the Borrower to form or acquire the Guarantor that the Borrower cause the Guarantor to execute and deliver to the Lender this Guaranty; and

WHEREAS, the board of directors of the Guarantor has determined that this Guaranty may reasonably be expected to benefit, directly or indirectly, the Guarantor;

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guarantor agrees as follows:

1. The Guarantor, as primary obligor and not as surety, hereby irrevocably and unconditionally guarantees, independently of the Borrower, to the Guaranteed Parties the due and punctual payment when due by the Borrower of all amounts now or hereafter owed by the Borrower to the Guaranteed Parties in connection with the Credit Agreement, including, without limitation, the Obligations and all other amounts payable under the Credit Agreement, the Notes and the other Loan Documents to which the Borrower is a party, whether principal, interest or other amounts, including, without limitation, attorneys' fees and costs of collection. The obligations of the Borrower guaranteed hereby and described in the preceding sentence are hereinafter referred to as the "Payment Obligations". The Guarantor, as primary obligor and not as surety, also hereby irrevocably and unconditionally guarantees, independently of the Borrower, to the Guaranteed Parties the complete observance, fulfillment and performance by the Borrower of all the terms and conditions of the Credit Agreement and all other Loan Documents to which the Borrower is or will be a party. The obligations of the Borrower guaranteed hereby and described in the immediately preceding sentence are hereinafter referred to as the "Performance Obligations".

2. The Guarantor hereby agrees that in the event that the Borrower fails to pay any Payment Obligations or the Borrower fails to perform any Performance Obligations for any reason (including, without limitation, the liquidation, dissolution, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceedings affecting the status, existence, assets or obligations of the Borrower, or the disaffirmance by the Borrower in any such proceeding of any Loan Document to which the Borrower is a party), the

Guarantor will pay such Payment Obligations and perform such Performance Obligations within five (5) days (the "Due Date") following the date on which written demand is made by the Administrative Agent or the Collateral Agent.

3.

5. The Guarantor waives notice of the acceptance of this Guaranty and of the performance or nonperformance by the Borrower, demand for payment or performance from the Borrower, or any other Person and notice of nonpayment or failure to perform on the part of the Borrower and all demands whatsoever, other than the demand for payment or performance hereunder provided for in paragraph 2 hereof. To the extent allowed by applicable law, the Guarantor expressly waives and relinquishes all rights and remedies now or hereafter accorded by applicable law to guarantors and sureties, including, without limitation, any defense, right of offset or setoff, or other claim which Guarantor may have against the Borrower or any of the Guaranteed Parties or which the Borrower may have against any of the Guaranteed Parties or the holders of the Notes.

6. No amendment of or supplement to this Guaranty, or waiver or modification of or consent under the terms hereof, shall be effective unless evidenced by an instrument in writing signed by the Guarantor and each of the Guaranteed Parties.

7. All payments hereunder shall be made in the currency of the United States of America and at the place and in the manner as provided in the Credit Agreement and the Notes for payments by the Borrower.
