ARTICLE II - The Loans and Letters of Credit

Section 2.1 Commitments to Lend; Notes. Subject to the terms and conditions hereof, each Lender agrees to make loans to Borrower (herein called such Lender’s “Revolving Loans”) upon Borrower’s request from time to time during the Commitment Period, provided that (a) subject to Section 3.3, Section 3.4, and Section 3.6, all Lenders are requested to make Revolving Loans of the same Type in accordance with their respective Percentage Shares and as part of the same Borrowing, and (b) after giving effect to such Revolving Loans (i) the sum of the Facility Usage and the principal amount of SG Obligations then outstanding does not exceed (ii) the lesser of the Aggregate Commitments or the Borrowing Base determined as of the date on which the requested Revolving Loans are to be made. The aggregate amount of all Revolving Loans in any Borrowing of Base Rate Loans must be greater than or equal to $500,000 or a higher integral multiple of $100,000 or must equal the remaining Availability, and the aggregate amount of all Revolving Loans in any Borrowing of Eurodollar Loans must be greater than or equal to $3,000,000 or any higher integral multiple of $1,000,000 or must equal the remaining Availability. Borrower may have no more than ten Borrowings of Eurodollar Loans outstanding at any time. The obligation of Borrower to repay to each Lender the aggregate amount of all

Loans made by such Lender, together with interest accruing in connection therewith, shall be evidenced by a single promissory note (herein called such Lender’s “Note”) made by Borrower payable to the order of such Lender in the form of Exhibit A with appropriate insertions. The amount of principal owing on any Lender’s Note at any given time shall be the aggregate amount of all Loans theretofore made by such Lender minus all payments of principal theretofore received by such Lender on such Note. Interest on each Note shall accrue and be due and payable as provided herein and therein. Each Note shall be due and payable as provided herein and therein, and shall be due and payable in full on the Maturity Date. Subject to the terms and conditions hereof, Borrower may borrow, repay, and reborrow hereunder.

Section 2.2 Requests for New Revolving Loans. Borrower must give to Administrative Agent written or electronic notice (or telephonic notice promptly confirmed in writing) of any requested Borrowing of new Revolving Loans to be advanced by Lenders. Each such notice constitutes a “Borrowing Notice” hereunder and must:

(a) specify (i) the aggregate amount of any such Borrowing of new Base Rate Loans and the date on which such Base Rate Loans are to be advanced, or (ii) the aggregate amount of any such Borrowing of new Eurodollar Loans, the date on which such Eurodollar Loans are to be advanced (which shall be the first day of the Interest Period which is to apply thereto), and the length of the applicable Interest Period; and

(b) be received by Administrative Agent not later than 11:00 a.m., Denver, Colorado time on, (i) the Business Day preceding the day on which any such Base Rate Loans are to be made, or (ii) the third Business Day preceding the day on which any such Eurodollar Loans are to be made.

Each such written request or confirmation must be made in the form and substance of the “Borrowing Notice” attached hereto as Exhibit B-1, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Borrowing Notice, Administrative Agent shall give each Lender prompt notice of the terms thereof. If all conditions precedent to such new Revolving Loans have been met, each Lender will on the date requested promptly remit to Administrative Agent at Administrative Agent’s office in Denver, Colorado the amount of such Lender’s new Revolving Loan in immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Revolving Loans have been neither met nor waived as provided herein, Administrative Agent shall promptly make such Revolving Loans available to Borrower. Unless Administrative Agent shall have received prompt notice from a Lender that such Lender will not make available to Administrative Agent such Lender’s new Revolving Loan, Administrative Agent may in its discretion assume that such Lender has made such Revolving Loan available to Administrative Agent in accordance with this section and Administrative Agent may if it chooses, in reliance upon such assumption, make such Revolving Loan available to Borrower. In such event, if a Lender has not in fact made its share of the applicable Revolving Loan available to Administrative Agent, then the applicable Lender and Borrower severally agree to pay to 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 Borrower to but excluding the date of payment to Administrative

Agent, at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by Administrative Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by Borrower, the interest rate applicable to Base Rate Loans. If Borrower and such Lender shall pay such interest to Administrative Agent for the same or an overlapping period, Administrative Agent shall promptly remit to Borrower the amount of such interest paid by Borrower for such period. If such Lender pays its share of the applicable Borrowing to Administrative Agent, then the amount so paid shall constitute such Lender’s Revolving Loan included in such Borrowing. Any payment by Borrower shall be without prejudice to any claim Borrower may have against a Lender that shall have failed to make such payment to Administrative Agent.

Section 2.3 Continuations and Conversions of Existing Loans. Borrower may make the following elections with respect to Revolving Loans already outstanding: to convert Base Rate Loans to Eurodollar Loans, to convert Eurodollar Loans to Base Rate Loans on the last day of the Interest Period applicable thereto, and to continue Eurodollar Loans beyond the expiration of such Interest Period by designating a new Interest Period to take effect at the time of such expiration. In making such elections, Borrower may combine existing Revolving Loans made pursuant to separate Borrowings into one new Borrowing or divide existing Revolving Loans made pursuant to one Borrowing into separate new Borrowings, provided that Borrower may have no more than ten Borrowings of Eurodollar Loans outstanding at any time. To make any such election, Borrower must give to Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of any such Conversion or Continuation of existing Revolving Loans, with a separate notice given for each new Borrowing. Each such notice constitutes a “Continuation/Conversion Notice” hereunder and must:

(a) specify the existing Revolving Loans which are to be Continued or Converted;

(b) specify (i) the aggregate amount of any Borrowing of Base Rate Loans into which such existing Revolving Loans are to be continued or converted and the date on which such Continuation or Conversion is to occur, or (ii) the aggregate amount of any Borrowing of Eurodollar Loans into which such existing Revolving Loans are to be continued or converted, the date on which such Continuation or Conversion is to occur (which shall be the first day of the Interest Period which is to apply to such Eurodollar Loans), and the length of the applicable Interest Period; and

(c) be received by Administrative Agent not later than 11:00 a.m., Denver, Colorado time, on (i) the day on which any such Continuation or Conversion to Base Rate Loans is to occur, or (ii) the third Business Day preceding the day on which any such Continuation or Conversion to Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and substance of the “Continuation/Conversion Notice” attached hereto as Exhibit C, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Continuation/Conversion Notice, Administrative Agent shall give each Lender prompt notice of the terms thereof. Each Continuation/Conversion Notice shall be irrevocable and binding on Borrower. During the continuance of any Default, Borrower may not

make any election to convert existing Revolving Loans into Eurodollar Loans or continue existing Revolving Loans as Eurodollar Loans. If (due to the existence of a Default or for any other reason) Borrower fails to timely and properly give any Continuation/Conversion Notice with respect to a Borrowing of existing Eurodollar Loans at least three days prior to the end of the Interest Period applicable thereto, such Eurodollar Loans shall automatically be converted into Base Rate Loans at the end of such Interest Period. No new funds shall be repaid by Borrower or advanced by any Lender in connection with any Continuation or Conversion of existing Revolving Loans pursuant to this section, and no such Continuation or Conversion shall be deemed to be a new advance of funds for any purpose; such Continuations and Conversions merely constitute a change in the interest rate applicable to already outstanding Revolving Loans. Notwithstanding anything to the contrary herein, a Swing Line Loan may not be converted to a Eurodollar Loan.

Section 2.4 Use of Proceeds. Borrower shall use all Loans to refinance Existing Indebtedness of Borrower including existing indebtedness under the Existing Credit Documents, to make acquisitions permitted by this Agreement, to finance capital expenditures, to refinance Matured LC Obligations, to refinance the 2014 Notes as permitted by Section 7.1, and to provide working capital for its operations and for other general business purposes. Borrower shall use all Letters of Credit for its general corporate purposes. In no event shall the funds from any Loan or any Letter of Credit be used directly or indirectly by any Person for personal, family, household or agricultural purposes or for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any “margin stock” (as such term is defined in Regulation U promulgated by the Board of Governors of the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such margin stock. Borrower represents and warrants that Borrower is not engaged principally, or as one of Borrower’s important activities, in the business of extending credit to others for the purpose of purchasing or carrying such margin stock.

Section 2.5 Interest Rates and Fees.

(a) Base Rate Loans. So long as no Event of Default has occurred and is continuing, all Base Rate Loans (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the Adjusted Base Rate in effect on such day. If an Event of Default has occurred and is continuing, all Base Rate Loans (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the applicable Default Rate in effect on such day. On each Interest Payment Date Borrower shall pay to the holder hereof all unpaid interest which has accrued on the Base Rate Loans to but not including such Interest Payment Date.

(b) Eurodollar Loans. So long as no Event of Default has occurred and is continuing, each Eurodollar Loan (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day during the related Interest Period at the related Adjusted Eurodollar Rate in effect on such day. If an Event of Default has occurred and is continuing, all Eurodollar Loans (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the applicable Default Rate in effect on such day. On each Interest Payment Date relating to such Eurodollar Loan, Borrower

shall pay to the holder hereof all unpaid interest which has accrued on such Eurodollar Loan to but not including such Interest Payment Date.

(c) Swing Line Loans. So long as no Default has occurred and is continuing, each Swing Line Loan (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Adjusted Base Rate or at such other rate per annum as may be agreed upon in writing by Borrower and Swing Line Lender. If an Event of Default has occurred and is continuing, all Swing Line Loans (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the applicable Default Rate in effect on such day. On each Interest Payment Date Borrower shall pay to the holder hereof all unpaid interest which has accrued on the Swing Line Loans to but not including such Interest Payment Date.

(d) Past Due Principal and Interest. All past due principal of and past due interest on the Loans shall bear interest on each day outstanding at the Default Rate in effect on such day, and such interest shall be due and payable daily as it accrues.

(e) Commitment Fees. In consideration of each Lender’s commitment to make Loans, Borrower will pay to Administrative Agent for the account of each Lender a commitment fee determined on a daily basis by applying the Commitment Fee Rate to such Lender’s Percentage Share of the Availability (calculated excluding outstanding Swing Line Loans) each day during the Commitment Period. This commitment fee shall be due and payable in arrears on the last day of each Fiscal Quarter and at the end of the Commitment Period.

(f) Administrative Agent’s Fees. In addition to all other amounts due to Administrative Agent under the Loan Documents, Borrower will pay fees to Administrative Agent as described in an Engagement Letter dated September 17, 2010 among Administrative Agent, Xxxxx Fargo Securities, LLC and Borrower.

Section 2.6 Optional Prepayments.

(a) Borrower may from time to time and without premium or penalty prepay the Notes, in whole or in part, so long as the aggregate amount of Base Rate Loans prepaid at any time must be equal to $500,000 or a higher integral multiple of $100,000, and the aggregate amount of Eurodollar Loans prepaid at any time must be equal to $3,000,000 or any higher integral multiple of $1,000,000; provided that if Borrower prepays any Base Rate Loan, it shall give notice to Administrative Agent at least one Business Day’s prior notice to the date such prepayment is made; and further provided that if Borrower prepays any Eurodollar Loan, it shall give notice to Administrative Agent at least three Business Days’ prior to the date such prepayment is made and pay to Lenders any amounts due under Section 3.5.

(b) Borrower may, upon notice to the Swing Line Lender (with a copy to Administrative Agent), prepay Swing Line Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Swing Line Lender and Administrative Agent not later than 2:00 p.m. Denver, Colorado time on the date of the prepayment, and (ii) any such prepayment shall be in a minimum principal amount of $100,000.

Each such notice shall specify the date and amount of such prepayment. If such notice is given by Borrower, Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.

Section 2.7 Mandatory Prepayments.

(a) If at any time the sum of the Facility Usage and the principal amount of SG Obligations then outstanding is in excess of the lesser of the Borrowing Base or the Aggregate Commitments (such excess being herein called a “Borrowing Base Deficiency”), Borrower shall within 30 days after Administrative Agent gives notice to Borrower of such Borrowing Base Deficiency elect to take any of the following actions or a combination thereof:

(i) prepay the SG Obligations and/or the principal of the Obligations in an aggregate amount at least equal to such Borrowing Base Deficiency in a single payment due and payable on the 30th day after the date on which Administrative Agent gives notice of such Borrowing Base Deficiency to Borrower (or, if the Loans have been paid in full, pay to LC Issuer Cash Collateral as required under Section 2.16(a)), or

(ii) prepay the SG Obligations and/or the principal of the Obligations in an aggregate amount at least equal to such Borrowing Base Deficiency in two equal installments, one being due and payable on the 90th day after the date on which Administrative Agent gives notice of such Borrowing Base Deficiency to Borrower and the other being payable on the 180th day after the date on which such notice is given to Borrower (or, if the Loans have been paid in full, pay to LC Issuer Cash Collateral as required under Section 2.16(a)), or

(iii) give notice to Administrative Agent that Borrower desires to provide (or cause to be provided by other Restricted Persons) Administrative Agent with deeds of trust, mortgages, chattel mortgages, security agreements, financing statements and other security documents in form and substance similar to the Security Documents previously delivered to Administrative Agent (with any changes required to conform to changes in Law or changes in the type of collateral covered thereby), and otherwise reasonably satisfactory to Administrative Agent, granting, confirming, and perfecting first and prior liens or security interests in collateral acceptable to Supermajority Lenders subject to no liens other than Permitted Liens, to the extent needed to allow Supermajority Lenders to increase the Borrowing Base (as they in their reasonable discretion deem consistent with prudent oil and gas banking industry lending standards at the time) to an amount which eliminates such Borrowing Base Deficiency, and such Security Documents shall be executed and delivered to Administrative Agent within thirty days after Administrative Agent confirms to Borrower what collateral shall be required. If, prior to any such specification by Administrative Agent, Required Lenders determine that the giving of such Security Documents will not serve to eliminate such Borrowing Base Deficiency, then, within five Business Days after receiving notice of such determination from Administrative Agent, Borrower will elect to make, and will thereafter make, the prepayments specified in the preceding clause (i) or (ii) of this subsection (a).

(b) Immediately upon the reduction of the Borrowing Base pursuant to Section 7.5 or Section 7.3(g), Borrower shall make a mandatory prepayment on the Loans in an amount, if any, required to eliminate any Borrowing Base Deficiency.

(c) Each prepayment of principal under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid and any amounts due under Section 3.4. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment.

Section 2.8 Initial Borrowing Base. During the period from the date hereof until the next Determination Date the Borrowing Base shall be $875,000,000 (the “Initial Borrowing Base”).

Section 2.9 Subsequent Redeterminations of Borrowing Base.

(a) Scheduled Determinations of Borrowing Base. By March 15 and September 15 of each year Borrower shall furnish to each Lender all information, reports and data which Administrative Agent has then requested concerning Restricted Persons’ businesses and properties (including their Mineral Interests and the reserves and production relating thereto), together with the Engineering Report described in Section 6.2(d) or 6.2(e), as applicable. Within thirty days after receiving such information, reports and data, or as promptly thereafter as practicable, Required Lenders and Administrative Agent shall agree upon an amount for the Borrowing Base (provided that Supermajority Lenders and Administrative Agent must agree to any increase in the Borrowing Base) and Administrative Agent shall by notice to Borrower designate such amount as the new Borrowing Base available to Borrower hereunder, which designation shall take effect immediately on the date such notice is sent (herein called a “Determination Date”) and shall remain in effect until but not including the next date as of which the Borrowing Base is redetermined. If Borrower does not furnish all such information, reports and data by the date specified in the first sentence of this section, Administrative Agent may nonetheless designate the Borrowing Base at any amount which Required Lenders determine and may redesignate the Borrowing Base from time to time thereafter (provided that Supermajority Lenders and Administrative Agent must agree to any increase in the Borrowing Base) until each Lender receives all such information, reports and data, whereupon Required Lenders shall designate a new Borrowing Base as described above. Required Lenders shall determine the amount of the Borrowing Base in their sole discretion consistent with normal and customary oil and gas lending practice of the Lenders based upon the loan collateral value which they in their discretion assign to the various Mineral Interests of Restricted Persons at the time in question and based upon such other credit factors (including without limitation the assets, liabilities, cash flow, hedged and unhedged exposure to price, foreign exchange rate, and interest rate changes, business, properties, prospects, management and ownership of Borrower and its Affiliates) as they in their discretion deem significant. It is expressly understood that Lenders and Administrative Agent have no obligation to agree upon or designate the Borrowing Base at any particular amount, whether in relation to the Maximum Credit Amount or otherwise, and that Lenders’ commitments to advance funds hereunder are determined by reference to the Borrowing Base from time to time in effect.

(b) Lenders’ Special Redeterminations of Borrowing Base. In addition to Scheduled Redeterminations, Required Lenders shall be permitted to make a Special Redetermination of the Borrowing Base (i) once between each two consecutive Scheduled Redeterminations, (ii) contemporaneously with each issuance of Permitted Unsecured Debt if requested by Administrative Agent pursuant to Section 2.9(e), (iii) when permitted by Section 7.3(g), and (iv) when permitted by Section 7.5. Any request by Administrative Agent pursuant to this Section 2.9(b) shall be submitted to Borrower. As soon as reasonably possible, Borrower shall deliver to Administrative Agent and Lenders an Engineering Report prepared as of a date which is no more than thirty (30) days prior to the date of such request (or, in case of a request made on the 31st day of any calendar month, 31 days), which shall be delivered on or before the date that is thirty (30) days after its receipt of such notice from Administrative Agent.

(c) Borrower’s Special Redetermination of Borrowing Base. In addition to Scheduled Redeterminations, Borrower shall be permitted to request a Special Redetermination of the Borrowing Base (i) once between each two consecutive Scheduled Redeterminations, and (ii) when permitted by Section 2.9(e). Such request shall be submitted to Administrative Agent and Lenders and at the time of such request Borrower shall (i) deliver to Administrative Agent and each Lender an Engineering Report prepared as of a date which is no more than thirty (30) days prior to the date of such request (or, in the case of a request made on the 31st day of any calendar month, 31 days) and (ii) notify Administrative Agent and each Lender of the Borrowing Base requested by Borrower in connection with such Special Redetermination.

(d) Procedures for Special Redeterminations. Any Special Redetermination shall be made by Lenders in accordance with the procedures and standards set forth in Section 2.9(a).

(e) Reduction of Borrowing Base Upon Issuance of Permitted Unsecured Debt. Notwithstanding anything to the contrary contained herein, each time Borrower issues any Permitted Unsecured Debt, on the date of issuance thereof the Borrowing Base then in effect shall be reduced automatically by an amount equal to the product of 0.25 and the stated principal amount of the Permitted Unsecured Debt so issued (excluding, for the avoidance of doubt, any Permitted Refinancing and the amount of cash proceeds of such Permitted Unsecured Debt applied contemporaneously with the issuance thereof to the 2014 Notes (as permitted by the last sentence of Section 7.1)). The Borrowing Base as so reduced shall become the new Borrowing Base immediately upon such date of issuance and shall remain in effect until the next date as of which the Borrowing Base is redetermined pursuant to this Agreement. For purposes of this Section 2.9(e), if any such Permitted Unsecured Debt is issued at a discount or otherwise sold for less than “par”, the reduction shall be calculated based upon the stated principal amount without reference to such discount. Notwithstanding the foregoing, (i) within thirty (30) days after the date on which such Permitted Unsecured Debt is issued, Administrative Agent may request an additional Special Redetermination of the Borrowing Base pursuant to Section 2.9(b), and (ii) within thirty (30) days after each repayment of Permitted Unsecured Debt in a cumulative amount of not less than $100,000,000 between successive Determination Dates, Borrower may request an additional Special Redetermination of the Borrowing Base pursuant to Section 2.9(c); and in either case the Borrowing Base will be redetermined in accordance with Section 2.9(b) or 2.9(c), as applicable.

(f) Reduction of Borrowing Base in Connection with Hedging Contract Modifications and Asset Sales. In addition to Scheduled Redeterminations, Special Redeterminations and automatic reductions of the Borrowing Base as provided in Section 2.9(e), the Borrowing Base may be reduced from time to time as provided in Sections 7.3 and Section 7.5.

(g) Aggregate Commitment Reduction. In the event that the Borrowing Base is reduced pursuant to this Agreement, the Aggregate Commitment will be automatically reduced, ratably among the Lenders, to an amount equal to the amount of such reduced Borrowing Base, and Administrative Agent shall prepare and distribute a new Lenders Schedule that reflects such reduced Aggregate Commitment and each Lender’s individual ratable Commitment comprising a part thereof. Such Lenders Schedule shall be effective immediately upon such distribution.

Section 2.10 Changes in Amount of Aggregate Commitment.

(a) Reductions. Borrower may at any time reduce the Aggregate Commitment in whole, or in part ratably among the Lenders in the amount of $5,000,000 or any higher integral multiple of $1,000,000, upon at least three Business Days’ written notice to Administrative Agent, which notice shall specify the amount of any such reduction, provided, however, that the amount of the Aggregate Commitment may not be reduced below the Facility Usage and may not be reinstated, except as provided in Section 2.10(b).

(b) Increases. Borrower shall have the right (in consultation with Administrative Agent), without the consent of any of Lenders, to cause from time to time an increase in the Aggregate Commitment by adding to this Agreement one or more additional Eligible Assignees to become Lenders pursuant to a joinder agreement in form and substance reasonably satisfactory to Administrative Agent and its counsel or by allowing one or more Lenders to increase their respective Commitments, provided, however, (i) no Default shall exist, (ii) no such increase shall result in the Aggregate Commitment exceeding the Maximum Credit Amount, (iii) no such increase shall be in an amount less than $5,000,000, and (iv) no Lender’s Commitment shall be increased without such Lender’s consent.

(c) Procedures for Increases. If the Aggregate Commitment is increased in accordance with Section 2.10(b), Administrative Agent and Borrower shall determine the effective date (the “Increase Effective Date”) and the final allocation of such increase. The Administrative Agent shall promptly notify Borrower and Lenders of the final allocation of such increase and the Increase Effective Date. As a condition precedent to such increase, Borrower shall deliver to Administrative Agent a certificate of Borrower dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by an authorized officer of Borrower (i) certifying and attaching the resolutions (or governing board minutes) adopted by Borrower approving or consenting to such increase, and (ii) certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article V and the other Loan Documents made by it are true and correct in all material respects on and as of the Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct in all material respects as of such earlier date, and (B) no Default exists. Borrower shall prepay any Loans outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 3.4) to the extent

necessary to keep the outstanding Loans ratable with any revised Percentage Shares arising from any nonratable increase in the Commitments under this section. This section shall supersede any provisions in Sections 9.6 or 10.1 to the contrary.

Section 2.11 Letters of Credit. Subject to the terms and conditions hereof, Borrower may during the Commitment Period request LC Issuer to issue, increase the amount of or otherwise amend or extend one or more Letters of Credit, provided that, after taking such Letter of Credit into account:

(a) the sum of the Facility Usage and the principal amount of the SG Obligations then outstanding does not exceed the lesser of the Aggregate Commitments or the Borrowing Base determined as of the date on which the requested Letter of Credit is to be issued;

(b) the aggregate amount of LC Obligations at such time does not exceed the LC Sublimit;

(c) the expiration date of such Letter of Credit (as extended if applicable) is prior to the Letter of Credit Termination Date;

(d) such Letter of Credit is to be used for general corporate purposes of Restricted Persons;

(e) such Letter of Credit is not directly or indirectly used to assure payment of or otherwise support any Indebtedness of any Person except Indebtedness of Restricted Persons;

(f) the issuance of such Letter of Credit will be in compliance with all applicable governmental restrictions, policies, and guidelines and will not subject LC Issuer to any cost which is not reimbursable under Article III;

(g) the form and terms of such Letter of Credit are acceptable to LC Issuer in its sole and absolute discretion;

(h) no Lender is at such time an Impacted Lender hereunder, unless LC Issuer has entered into arrangements with Borrower or such Lender reasonably satisfactory to LC Issuer, provided that Borrower and LC Issuer agree that the delivery of cash collateral to LC Issuer shall constitute satisfactory arrangements with Borrower or such Lender to eliminate such LC Issuer’s risk with respect to such Lender; and

(i) all other conditions in this Agreement to the issuance of such Letter of Credit have been satisfied.

LC Issuer will honor any such request if the foregoing conditions (a) through (i) (in the following Section 2.12 called the “LC Conditions”) have been met as of the date of issuance of such Letter of Credit. LC Issuer may choose to honor any such request for any other Letter of Credit but has no obligation to do so and may refuse to issue any other requested Letter of Credit for any reason which LC Issuer in its sole discretion deems relevant. All Existing Letters of Credit shall be deemed to have been issued pursuant hereto and, from and after the date hereof, shall be subject to and governed by the terms and conditions hereof.

Section 2.12 Requesting Letters of Credit.

(a) Borrower must make written application for any Letter of Credit or amendment or extension of any Letter of Credit at least five Business Days before the date on which Borrower desires for LC Issuer to issue such Letter of Credit. By making any such written application Borrower shall be deemed to have represented and warranted that the LC Conditions described in Section 2.11 will be met as of the date of issuance of such Letter of Credit. Each such written application for a Letter of Credit must be made in writing in the form customarily used by LC Issuer, the terms and provisions of which are hereby incorporated herein by reference (or in such other form as may mutually be agreed upon by LC Issuer and Borrower).

(b) If Borrower so requests in any applicable LC Application, LC Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit LC Issuer to prevent any such extension at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by LC Issuer, Borrower shall not be required to make a specific request to LC Issuer for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) LC Issuer to permit the extension of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Termination Date; provided, however, that LC Issuer shall not permit any such extension if (i) LC Issuer has determined that it would not be permitted, or would have no obligation at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of Section 2.11 or otherwise), or (ii) it has received notice (which notice may be by telephone or in writing) on or before the day that is five Business Days before the Non-Extension Notice Date (A) from Administrative Agent that the Required Lenders have elected not to permit such extension or (B) from Administrative Agent, any Lender or Borrower that one or more of the applicable conditions specified in Section 4.2 is not then satisfied, and in each such case directing LC Issuer not to permit such extension.

(c) Two Business Days after the LC Conditions for a Letter of Credit have been met as described in Section 2.11 (or if LC Issuer otherwise desires to issue such Letter of Credit), LC Issuer will issue such Letter of Credit at LC Issuer’s office in San Francisco, California. If any provisions of any LC Application conflict with any provisions of this Agreement, the provisions of this Agreement shall govern and control.

(d) Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary of Borrower, Borrower shall be obligated to reimburse LC Issuer hereunder for any and all drawings under such Letter of Credit. Borrower hereby acknowledges that the issuance of Letters of Credit for the account of such Subsidiaries inures to the benefit of Borrower, and that Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

Section 2.13 Reimbursement and Participations.

(a) Reimbursement by Borrower. Each Matured LC Obligation shall constitute a loan by LC Issuer to Borrower. Borrower promises to pay to LC Issuer, or to LC Issuer’s order, on demand, the full amount of each Matured LC Obligation, together with interest thereon at the Default Rate applicable to Base Rate Loans.

(b) Letter of Credit Loans. If the beneficiary of any Letter of Credit makes a draft or other demand for payment thereunder, then Borrower may, during the interval between the making thereof and the honoring thereof by LC Issuer, request Lenders to make Revolving Loans to Borrower in the amount of such draft or demand, which Revolving Loans shall be made concurrently with LC Issuer’s payment of such draft or demand and shall be immediately used by LC Issuer to repay the amount of the resulting Matured LC Obligation. Such a request by Borrower shall be made in compliance with all of the provisions hereof, provided that for the purposes of the first sentence of Section 2.1(a), the amount of such Revolving Loans shall be considered, but the amount of the Matured LC Obligation to be concurrently paid by such Revolving Loans shall not be considered.

(c) Participation by Lenders. LC Issuer irrevocably agrees to grant and hereby grants to each Lender, and — to induce LC Issuer to issue Letters of Credit hereunder — each Lender irrevocably agrees to accept and purchase and hereby accepts and purchases from LC Issuer, on the terms and conditions hereinafter stated and for such Lender’s own account and risk, an undivided interest equal to such Lender’s Percentage Share of LC Issuer’s obligations and rights under each Letter of Credit issued hereunder and the amount of each Matured LC Obligation paid by LC Issuer thereunder. Each Lender unconditionally and irrevocably agrees with LC Issuer that, if a Matured LC Obligation is paid under any Letter of Credit for which LC Issuer is not reimbursed in full by Borrower in accordance with the terms of this Agreement and the related LC Application (including any reimbursement by means of concurrent Loans or by the application of Cash Collateral), such Lender shall (in all circumstances and without set-off or counterclaim) pay to LC Issuer on demand, in immediately available funds at LC Issuer’s address for notices hereunder, such Lender’s Percentage Share of such Matured LC Obligation (or any portion thereof which has not been reimbursed by Borrower). Each Lender’s obligation to pay LC Issuer pursuant to the terms of this subsection is irrevocable and unconditional. If any amount required to be paid by any Lender to LC Issuer pursuant to this subsection is paid by such Lender to LC Issuer within three Business Days after the date such payment is due, LC Issuer shall in addition to such amount be entitled to recover from such Lender, on demand, interest thereon calculated from such due date at the Federal Funds Rate. If any amount required to be paid by any Lender to LC Issuer pursuant to this subsection is not paid by such Lender to LC Issuer within three Business Days after the date such payment is due, LC Issuer shall in addition to such amount be entitled to recover from such Lender, on demand, interest thereon calculated from such due date at the Default Rate applicable to Base Rate Loans.

(d) Distributions to Participants. Whenever LC Issuer has in accordance with this section received from any Lender payment of such Lender’s Percentage Share of any Matured LC Obligation, if LC Issuer thereafter receives any payment of such Matured LC Obligation or any payment of interest thereon (whether directly from Borrower or by application of Cash Collateral or otherwise, and excluding only interest for any period prior to LC Issuer’s demand that such Lender make such payment of its Percentage Share), LC Issuer will distribute to such Lender its Percentage Share of the amounts so received by LC Issuer; provided, however, that if

any such payment received by LC Issuer must thereafter be returned by LC Issuer, such Lender shall return to LC Issuer the portion thereof which LC Issuer has previously distributed to it.

(e) Calculations. A written advice setting forth in reasonable detail the amounts owing under this section, submitted by LC Issuer to Borrower or any Lender from time to time, shall be conclusive, absent manifest error, as to the amounts thereof.

(f) If any Lender is an Impacted Lender, Borrower may from time to time provide cash collateral to LC Issuer, in an amount equal to the Percentage Shares of all Impacted Lenders’ in the LC Obligations (the “Impacted Lenders’ Percentage”), to secure the obligations of such Impacted Lenders under this Section 2.13. Such cash collateral shall be used to reimburse the Impacted Lenders’ Percentage of drawings under Letters of Credit and other obligations owing by Impacted Lenders to LC Issuer.

Section 2.14 Letter of Credit Fees. In consideration of LC Issuer’s issuance of any Letter of Credit, Borrower agrees to pay (a) to Administrative Agent, for the account of all Lenders in accordance with their respective Percentage Shares, a letter of credit issuance fee at a rate equal to the Eurodollar Margin then in effect, and (b) to such LC Issuer for its own account, a letter of credit fronting fee at a rate equal to one-eighth of one percent (0.125%) per annum, but in no event less than $500 per annum; provided, however, any Letter of Credit Fees otherwise payable for the account of an Impacted Lender with respect to any Letter of Credit as to which such Impacted Lender has not provided Cash Collateral satisfactory to LC Issuer pursuant to Section 2.16 shall be payable, to the maximum extent permitted by applicable Law, to the other Lenders in accordance with the upward adjustments in their respective Applicable Percentages allocable to such Letter of Credit pursuant to Section 2.19(a)(iv), with the balance of such fee, if any, payable to LC Issuer for its own account. 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 due and payable on the last day of each Fiscal Quarter in arrears. In addition, Borrower will pay to LC Issuer LC Issuer’s customary fees for administrative issuance, amendment and drawing of each Letter of Credit.

Section 2.15 No Duty to Inquire.

(a) Drafts and Demands. LC Issuer is authorized and instructed to accept and pay drafts and demands for payment under any Letter of Credit without requiring, and without responsibility for, any determination as to the existence of any event giving rise to said draft, either at the time of acceptance or payment or thereafter. LC Issuer is under no duty to determine the proper identity of anyone presenting such a draft or making such a demand (whether by tested telex or otherwise) as the officer, representative or agent of any beneficiary under any Letter of Credit, and payment by LC Issuer to any such beneficiary when requested by any such purported officer, representative or agent is hereby authorized and approved. Borrower releases each Lender Party from, and agrees to hold each Lender Party harmless and indemnified against, any liability or claim in connection with or arising out of the subject matter of this section, which indemnity shall apply whether or not any such liability or claim is in any way or to any extent caused, in whole or in part, by any negligent act or omission of any kind by any Lender Party, provided only that no Lender Party shall be entitled to indemnification for that

portion, if any, of any liability or claim which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment.

(b) Extension of Maturity. If the maturity of any Letter of Credit is extended by its terms or by Law or governmental action, if any extension of the maturity or time for presentation of drafts or any other modification of the terms of any Letter of Credit is made at the request of any Restricted Person, or if the amount of any Letter of Credit is increased at the request of any Restricted Person, this Agreement shall be binding upon all Restricted Persons with respect to such Letter of Credit as so extended, increased or otherwise modified, with respect to drafts and property covered thereby, and with respect to any action taken by LC Issuer, LC Issuer’s correspondents, or any Lender Party in accordance with such extension, increase or other modification.

(c) Transferees of Letters of Credit. If any Letter of Credit provides that it is transferable, LC Issuer shall have no duty to determine the proper identity of anyone appearing as transferee of such Letter of Credit, nor shall LC Issuer be charged with responsibility of any nature or character for the validity or correctness of any transfer or successive transfers, and payment by LC Issuer to any purported transferee or transferees as determined by LC Issuer is hereby authorized and approved, and Borrower releases each Lender Party from, and agrees to hold each Lender Party harmless and indemnified against, any liability or claim in connection with or arising out of the foregoing, which indemnity shall apply whether or not any such liability or claim is in any way or to any extent caused, in whole or in part, by any negligent act or omission of any kind by any Lender Party, provided only that no Lender Party shall be entitled to indemnification for that portion, if any, of any liability or claim which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment.

Section 2.16 Cash Collateral.

(a) Certain Credit Support Events. Upon the request of Administrative Agent or LC Issuer (i) if LC Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in a Matured LC Obligation, or (ii) if, as of the Letter of Credit Termination Date, any LC Obligation for any reason remains outstanding, Borrower shall, in each case, immediately Cash Collateralize the then Outstanding Amount of all LC Obligations. If, after the making of all mandatory prepayments required under Section 2.7, the outstanding LC Obligations will exceed the Borrowing Base, then in addition to prepayment of the entire principal balance of the Loans required under Section 2.7, Borrower shall immediately Cash Collateralize the then outstanding LC Obligations in an amount equal to such excess. At any time that there shall exist an Impacted Lender, immediately upon the request of Administrative Agent, Swing Line Lender, or LC Issuer, Borrower shall deliver Cash Collateral to Administrative Agent in an amount sufficient to cover all Fronting Exposure (after giving effect to Section 2.19(a)(iv) and any Cash Collateral provided by the Impacted Lender).

(b) Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked deposit accounts at Administrative Agent. Borrower, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of) Administrative Agent, for the benefit of Administrative Agent, LC Issuer and the Lenders (including Swing Line Lender), and agrees to maintain, a first

priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.16(c). If at any time Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than Administrative Agent as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby, Borrower or the relevant Impacted Lender will, promptly upon demand by Administrative Agent, pay or provide to Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency.

(c) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of this Section 2.16 or Section 2.7, 2.9, 2.19 or 8.3 in respect of Letters of Credit or Swing Line Loans shall be held and applied to the satisfaction of the specific LC Obligations, Swing Line Loans, obligations to fund participations therein (including, as to Cash Collateral provided by an Impacted Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein.

(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Impacted Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 10.4(h)) or (ii) Administrative Agent’s good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of a Restricted Person shall not be released during the continuance of a Default or Event of Default (and following application as provided in this Section 2.16 may be otherwise applied in accordance with Section 8.3), and (y) the Impacted Lender providing Cash Collateral and LC Issuer or Swing Line Lender, as applicable, may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

Section 2.17 Swing Line Loans.

(a) The Swing Line. Subject to the terms and conditions set forth herein, the Swing Line Lender, in its sole and absolute discretion, may, in reliance upon the agreements of the other Lenders set forth in this Section 2.17, to make loans (each such loan, a “Swing Line Loan”) to Borrower from time to time on any Business Day during the Commitment Period in an aggregate amount not to exceed at any time outstanding the amount of the Swing Line Sublimit, notwithstanding the fact that such Swing Line Loans, when aggregated with the Swing Line Lender’s Percentage Share of the outstanding principal balance of Swing Line Lender’s Revolving Loans, may exceed the amount of the Swing Line Lender’s Commitment; provided, however, that (i) after giving effect to any Swing Line Loan, the sum of the Facility Usage and the principal amount of the SG Obligations then outstanding does not exceed the lesser of the Aggregate Commitment or the Borrowing Base as of the date on which the Swing Line Loan is to be made; (ii) that Borrower shall not use the proceeds of any Swing Line Loan to refinance any outstanding Swing Line Loan; and (iii) the Swing Line Lender shall have no obligation to make any Swing Line Loan. Within the foregoing limits, and subject to the other terms and

conditions hereof, Borrower may borrow under this Section 2.17, prepay under Section 2.6 and reborrow under this Section 2.17. Each Swing Line Loan shall bear interest at the Adjusted Base Rate and all outstanding Swing Line Loans shall be due and payable in full on the fifth and the twentieth day of each calendar month. Immediately upon the making of a Swing Line Loan, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swing Line Lender a risk participation in such Swing Line Loan in an amount equal to the product of such Lender’s Percentage Share times the amount of such Swing Line Loan.

(b) Borrowing Procedures. Each Swing Line Borrowing shall be made upon Borrower’s irrevocable notice to the Swing Line Lender and Administrative Agent, which may be given by telephone. Each such notice must be received by the Swing Line Lender and Administrative Agent not later than 1:00 p.m., Denver, Colorado time, on the requested borrowing date, and shall specify (i) the amount to be borrowed, which shall be a minimum of $100,000, and (ii) the requested borrowing date, which shall be a Business Day. Each such telephonic notice must be confirmed promptly by delivery to the Swing Line Lender and Administrative Agent of a written Swing Line Loan Notice appropriately completed. Promptly after receipt by the Swing Line Lender of any telephonic Swing Line Loan Notice, the Swing Line Lender will confirm with Administrative Agent (by telephone or in writing) that Administrative Agent has also received such Swing Line Loan Notice and, if not, the Swing Line Lender will notify Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swing Line Lender has received notice (by telephone or in writing) from Administrative Agent (including at the request of any Lender) prior to 2:00 p.m., Denver, Colorado time, on the date of the proposed Swing Line Borrowing (A) directing the Swing Line Lender not to make such Swing Line Loan as a result of the limitations set forth in the first proviso to the first sentence of Section 2.17(a), or (B) that one or more of the applicable conditions specified in Article IV is not then satisfied, then, subject to the terms and conditions hereof, the Swing Line Lender will, not later than 3:00 p.m., Denver, Colorado time, on the borrowing date specified in such Swing Line Loan Notice, make the amount of its Swing Line Loan available to Borrower at its office by crediting the account of Borrower on the books of the Swing Line Lender in immediately available funds.

(i) The Swing Line Lender at any time in its sole and absolute discretion may request, on behalf of Borrower (which hereby irrevocably authorizes the Swing Line Lender to so request on its behalf), that each Lender make a Revolving Loan in an amount equal to such Lender’s Percentage Share of the amount of Swing Line Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Borrowing Notice for purposes hereof) and in accordance with the requirements of Section 2.2, without regard to the minimum and multiples specified therein for the principal amount of Revolving Loans, but subject to the unutilized portion of the Aggregate Commitments and the conditions set forth in Section 4.2. The Swing Line Lender shall furnish Borrower with a copy of the applicable Borrowing Notice promptly after delivering such notice to Administrative Agent. Each Lender shall make an amount equal to its Percentage Share of the amount specified in such Borrowing Notice available to Administrative Agent in immediately available funds for the account of the Swing Line Lender at Administrative Agent’s office not later than 1:00 p.m.,

Denver, Colorado time, on the day specified in such Borrowing Notice, whereupon, subject to Section 2.17(c)(ii), each Lender that so makes funds available shall be deemed to have made a Revolving Loan to Borrower in such amount. Administrative Agent shall remit the funds so received to the Swing Line Lender.

(ii) If for any reason any Swing Line Loan cannot be refinanced by such a Revolving Loan in accordance with this Section 2.17(c), the request for Revolving Loans submitted by the Swing Line Lender as set forth herein shall be deemed to be a request by the Swing Line Lender that each of the Lenders fund its risk participation in the relevant Swing Line Loan and each Lender’s payment to Administrative Agent for the account of the Swing Line Lender pursuant to Section 2.17(c)(i) shall be deemed payment in respect of such participation.

(iii) If any Lender fails to make available to Administrative Agent for the account of the Swing Line Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.17(c) by the time specified in 2.17(c)(i), the Swing Line Lender shall be entitled to recover from such Lender (acting through Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swing Line Lender at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the Swing Line Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Swing Line Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Revolving Loan included in the relevant Swing Line Loan or funded participation in the relevant Swing Line Loan as the case may be. A certificate of the Swing Line Lender submitted to any Lender (through Administrative Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Lender’s obligation to make Revolving Loans or to purchase and fund risk participations in Swing Line Loans pursuant to this Section 2.17(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swing Line Lender, Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuation of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Revolving Loans pursuant to this Section 2.17(c) is subject to the conditions set forth in Section 4.2. No such funding of risk participations shall relieve or otherwise impair the obligation of Borrower to repay Swing Line Loans, together with interest provided herein.

(d) Repayment of Participations.

(i) At any time after any Lender has purchased and funded a risk participation in a Swing Line Loan, if the Swing Line Lender receives any payment on account of such

Swing Line Loan, the Swing Line Lender will distribute to such Lender its Percentage Share thereof in the same funds as those received by the Swing Line Lender.

(ii) If any payment received by the Swing Line Lender in respect of principal or interest on any Swing Line Loan is required to be returned by the Swing Line Lender under any of the circumstances described in Section 9.6 (including pursuant to any settlement entered into by the Swing Line Lender in its discretion), each Lender shall pay to the Swing Line Lender its Percentage Share thereof on demand of Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the Federal Funds Rate. Administrative Agent will make such demand upon the request of the Swing Line Lender. The obligations of the Lenders under this clause shall survive payment in full of the Obligations and the termination of this Agreement.

(e) Interest Account of Swing Line Lender. The Swing Line Lender shall be responsible for invoicing Borrower for interest on the Swing Line Loans. Until each Lender funds its Revolving Loan or risk participation pursuant to this Section 2.17 to refinance such Lender’s Percentage Share of any Swing Line Loan, interest in respect of such Percentage Share shall be solely for the account of the Swing Line Lender.

(f) Payments Directly to Swing Line Lender. Borrower shall make all payments of principal and interest in respect of the Swing Line Loans directly to the Swing Line Lender.

Section 2.18 Obligations of Lenders Several. The obligations of the Lenders hereunder to make Loans, to fund participations in Letters of Credit and Swing Line Loans, and to make payments pursuant to Section 2.2 are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under Section 10.4(b) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 10.4(b).

Section 2.19 Impacted Lenders.

(a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes an Impacted Lender, then, until such time as that Lender is no longer an Impacted Lender, to the extent permitted by applicable Law:

(i) Waivers and Amendments. That Impacted Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 10.1.

(ii) Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by Administrative Agent for the account of that Impacted Lender (whether voluntary or mandatory, at maturity, pursuant to Article III or VIII or otherwise, and including any amounts made available to Administrative Agent by that Impacted Lender pursuant to Section 6.14), shall be applied at such time or times as may be determined by Administrative Agent as follows: first, to the payment of any amounts owing by that Impacted Lender to Administrative Agent hereunder; second, to the

payment on a pro rata basis of any amounts owing by that Impacted Lender to LC Issuer or Swing Line Lender hereunder; third, if so determined by Administrative Agent or requested by LC Issuer or Swing Line Lender, to be held as Cash Collateral for future funding obligations of that Impacted Lender of any participation in any Swing Line Loan or Letter of Credit; fourth, as Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Impacted Lender has failed to fund its portion thereof as required by this Agreement, as determined by Administrative Agent; fifth, if so determined by Administrative Agent and Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of that Impacted Lender to fund Loans under this Agreement; sixth, to the payment of any amounts then owing to Lenders, LC Issuer, Swing Line Lender, or Lender Counterparties as a result of any judgment of a court of competent jurisdiction obtained by any Lender, LC Issuer, Swing Line Lender, or any Lender Counterparty against that Impacted Lender as a result of that Impacted Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts then owing to Borrower as a result of any judgment of a court of competent jurisdiction obtained by Borrower against that Impacted Lender as a result of that Impacted Lender’s breach of its obligations under this Agreement; and eighth, to that Impacted Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or Matured LC Obligations in respect of which that Impacted Lender has not fully funded its appropriate share and (y) such Loans or Matured LC Obligations were made at a time when the conditions set forth in Section 4.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and Matured LC Obligations owed to, all non-Impacted Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or Matured LC Obligations owed to, that Impacted Lender. Any payments, prepayments or other amounts paid or payable to an Impacted Lender that are applied (or held) to pay amounts owed by an Impacted Lender or to post Cash Collateral pursuant to this Section 2.19(a)(ii) shall be deemed paid to and redirected by that Impacted Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees. That Impacted Lender (x) shall not be entitled to receive any commitment fee pursuant to Section 2.5(e) for any period during which that Lender is an Impacted Lender (and Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Impacted Lender) and (y) shall be limited in its right to receive Letter of Credit Fees as provided in Section 2.14.

(iv) Reallocation of Percentage Shares to Reduce Fronting Exposure. During any period in which there is an Impacted Lender, for purposes of computing the amount of the obligation of each non-Impacted Lender to acquire, refinance or fund participations in Letters of Credit or Swing Line Loans pursuant to Sections 2.13 and 2.17, the “Percentage Share” of each non-Impacted Lender shall be computed without giving effect to the Commitment of that Impacted Lender; provided, that, (i) each such reallocation shall be given effect only if, at the date the applicable Lender becomes an Impacted Lender, no Default or Event of Default exists; and (ii) the aggregate obligation of each non-Impacted Lender to acquire, refinance or fund participations in Letters of Credit and Swing Line Loans shall not exceed the positive difference, if any, of (1) the

Commitment of that non-Impacted Lender minus (2) the aggregate outstanding amount of the Loans of that Lender.

(b) Impacted Lender Cure. If Borrower, Administrative Agent, Swing Line Lender and LC Issuer agree in writing in their discretion that an Impacted Lender should no longer be deemed to be an Impacted Lender, Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which conditions may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other Lenders or take such other actions as Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swing Line Loans to be held on a pro rata basis by the Lenders in accordance with their Percentage Shares (without giving effect to Section 2.19(a)(iv)), whereupon that Lender will cease to be an Impacted Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of Borrower while that Lender was an Impacted Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Impacted Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been an Impacted Lender.

ARTICLE III - Payments to Lenders

Section 3.1 General Procedures. Borrower will make each payment which it owes under the Loan Documents to Administrative Agent for the account of the Lender Party to whom such payment is owed, in lawful money of the United States of America, without set-off, deduction or counterclaim, and in immediately available funds. Each such payment must be received by Administrative Agent not later than 11:00 a.m., Denver, Colorado time, on the date such payment becomes due and payable. Any payment received by Administrative Agent after such time will be deemed to have been made on the next following Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. Each payment under a Loan Document shall be due and payable at the place set forth for Administrative Agent on Schedule 4 hereto. When Administrative Agent collects or receives money on account of the Obligations, Administrative Agent shall distribute all money so collected or received, and each Lender Party shall apply all such money so distributed, as follows (except as otherwise provided in Section 8.3):

(a) first, for the payment of all Obligations which are then due (and if such money is insufficient to pay all such Obligations, first to any reimbursements due to Administrative Agent under Section 6.9 or 10.4 and then to the partial payment of all other Obligations then due in proportion to the amounts thereof, or as Lender Parties shall otherwise agree);

(b) then for the prepayment of amounts owing under the Loan Documents (other than principal on the Notes) if so specified by Borrower;

(c) then for the prepayment of principal on the Notes, together with accrued and unpaid interest on the principal so prepaid; and

(d) last, for the payment or prepayment of any other Obligations.

All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal then due and payable, and last to any prepayment of principal and interest in compliance with Sections 2.6 and 2.7. All distributions of amounts described in any of subsections (b), (c) or (d) above shall be made by Administrative Agent pro rata to each Lender Party then owed Obligations described in such subsection in proportion to all amounts owed to all Lender Parties which are described in such subsection; provided that if any Lender then owes payments to LC Issuer for the purchase of a participation under Section 2.13(c) or to Administrative Agent under Section 10.4(b), any amounts otherwise distributable under this section to such Lender shall be deemed to belong to LC Issuer, or Administrative Agent, respectively, to the extent of such unpaid payments, and Administrative Agent shall apply such amounts to make such unpaid payments rather than distribute such amounts to such Lender.

Section 3.2 Increased Costs.

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

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

(ii) subject any Lender or LC Issuer to any Tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender or LC Issuer in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 3.5 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or LC Issuer); or

(iii) impose on any Lender or LC Issuer or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or LC Issuer of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or LC Issuer hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or LC Issuer, Borrower will pay to such Lender or LC Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or LC Issuer, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or LC Issuer determines that any Change in Law affecting such Lender or LC Issuer or any lending office of such Lender or such Lender’s or LC Issuer’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or LC Issuer’s capital or on the capital of such Lender’s or LC Issuer’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by LC Issuer, to a level below that which such Lender or LC Issuer or such Lender’s or LC Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or LC Issuer’s policies and the policies of such Lender’s or LC Issuer’s holding company with respect to capital adequacy), then from time to time Borrower will pay to such Lender or LC Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or LC Issuer or such Lender’s or LC Issuer’s holding company for any such reduction suffered. Notwithstanding the foregoing, for purposes of this Agreement, all requests, rules, guidelines, or directives in connection with the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act shall be deemed to be a Change in Law regardless of the date enacted, adopted or issued and all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Regulations and Supervisory Practices (or any successor or similar authority) or the United States financial regulatory authorities shall be deemed to be a Change in Law regardless of the date adopted, issued, promulgated or implemented.

(c) Certificates for Reimbursement. A certificate of a Lender or LC Issuer setting forth the amount or amounts necessary to compensate such Lender or LC Issuer or its holding company, as the case may be, as specified in subsection (a) or (b) of this Section 3.2 and delivered to Borrower shall be conclusive absent manifest error. Borrower shall pay such Lender or LC Issuer, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or LC Issuer to demand compensation pursuant to this Section 3.2 shall not constitute a waiver of such Lender’s or LC Issuer’s right to demand such compensation, provided that Borrower shall not be required to compensate a Lender or LC Issuer pursuant to this Section 3.2 for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender or LC Issuer, as the case may be, notifies Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or LC Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

Section 3.3 Illegality. If any Change in Law after the date hereof shall make it unlawful for any Lender Party to fund or maintain Eurodollar Loans, then, upon notice by such Lender Party to Borrower and Administrative Agent, (a) Borrower’s right to elect Eurodollar Loans from such Lender Party shall be suspended to the extent and for the duration of such illegality, (b) all Eurodollar Loans of such Lender Party which are then the subject of any Borrowing Notice and which cannot be lawfully funded shall be funded as Base Rate Loans of such Lender Party, and (c) all Eurodollar Loans of such Lender Party shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods

with respect to such Loans or within such earlier period as required by Law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, Borrower shall pay to such Lender Party such amounts, if any, as may be required pursuant to Section 3.4.

Section 3.4 Funding Losses. In addition to its other obligations hereunder, Borrower will indemnify each Lender Party against, and reimburse each Lender Party on demand for, any loss or expense incurred or sustained by such Lender Party (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by a Lender Party to fund or maintain Eurodollar Loans), as a result of (a) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Loan on a day other than the day on which the applicable Interest Period ends, (b) any payment or prepayment, whether required hereunder or otherwise, of a Loan made after the delivery, but before the effective date, of a Continuation/Conversion Notice requesting the continuation of outstanding Eurodollar Loans as, or the conversion of outstanding Base Rate Loans to, Eurodollar Loans, if such payment or prepayment prevents such Continuation/ Conversion Notice from becoming fully effective, (c) the failure of any Revolving Loan to be made or of any Continuation/Conversion Notice requesting the continuation of outstanding Eurodollar Loans as, or the conversion of outstanding Base Rate Loans to, Eurodollar Loans to become effective due to any condition precedent not being satisfied or due to any other action or inaction of any Restricted Person, (d) any Conversion (whether authorized or required hereunder or otherwise) of all or any portion of any Eurodollar Loan into a Base Rate Loan or into a different Eurodollar Loan on a day other than the day on which the applicable Interest Period ends, or (e) any assignment of a Eurodollar Loan on a day other than the last day of the Interest Period therefor as a result of a request by Borrower pursuant to Section 3.7(b). Such indemnification shall be on an after-tax basis.

Section 3.5 Taxes.

(a) Payment Free of Taxes. Any and all payments by or on account of any obligation of Borrower hereunder or under any other Loan Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if Borrower shall be required by applicable law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 3.5) Administrative Agent, Lender or LC Issuer, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make such deductions and (iii) Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) Indemnification by Borrower. Borrower shall indemnify Administrative Agent, each Lender and LC Issuer, within ten (10) days after demand therefor, for the full amount of

any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 3.5) paid by Administrative Agent, such Lender or LC Issuer, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to Borrower by a Lender or LC Issuer (with a copy to Administrative Agent), or by Administrative Agent on its own behalf or on behalf of a Lender or LC Issuer, shall be conclusive absent manifest error.

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

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

Without limiting the generality of the foregoing, in the event that Borrower is resident for tax purposes in the United States of America, any Foreign Lender shall deliver to Borrower and Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of Borrower or Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

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

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

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Internal Revenue Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Internal Revenue Code, (B) a “10 percent shareholder” of Borrower within the meaning of section 881(c)(3)(B) of the Internal Revenue Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Internal

Revenue Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

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

(f) Treatment of Certain Refunds. If Administrative Agent, a Lender or LC Issuer receives a refund of any Taxes or Other Taxes as to which it has been indemnified by Borrower or with respect to which Borrower has paid additional amounts pursuant to this Section 3.5, it shall pay to Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by Borrower under this Section 3.5 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of Administrative Agent, such Lender or LC Issuer, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that Borrower, upon the request of Administrative Agent, such Lender or LC Issuer, agrees to repay the amount paid over to Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to Administrative Agent, such Lender or LC Issuer in the event Administrative Agent, such Lender or LC Issuer is required to repay such refund to such Governmental Authority. This subsection shall not be construed to require Administrative Agent, any Lender or LC Issuer to make available its tax returns (or any other information relating to its taxes that it deems confidential) to Borrower or any other Person.

Section 3.6 Alternative Rate of Interest. If prior to the commencement of any Interest Period for a Borrowing of Eurodollar Loans:

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

(b) Administrative Agent is advised by Required Lenders that the Eurodollar Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

then Administrative Agent shall give notice thereof to Borrower and Lenders by telephone or facsimile as promptly as practicable thereafter and, until Administrative Agent notifies Borrower and Lenders that the circumstances giving rise to such notice no longer exist, (i) any Continuation/Conversion Notice that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Borrowing of Eurodollar Loans shall be ineffective and shall be deemed a request to continue such Borrowing as a Borrowing of Base Rate Loans and (ii) if any Borrowing Notice requests a Borrowing of Eurodollar Loans, such Borrowing shall be made as a Borrowing of Base Rate Loans. Upon receipt of such notice, Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Loans.

Section 3.7 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 3.2, or requires Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.5, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.2 or 3.5, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender is an Impacted Lender, or if any Lender requests compensation under Section 3.2 or gives notice to Borrower under Section 3.3 that it is unlawful for such Lender to fund or maintain Eurodollar Loans, or if Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.5, or if any Lender fails to consent to any increase in the Borrowing Base proposed by Administrative Agent, or if, in connection with any consent or approval of any proposed amendment, modification, waiver, or consent that requires consent of each Lender, the consent of Required Lenders shall have been obtained (or, if the consent of the Required Lenders is required and the consent of the Majority Lenders has been obtained) but any Lender has not so consented or approved (any such Lender, a “Non-Consenting Lender”), then Borrower may, at its sole expense and effort, upon notice to such Lender and Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.5), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(i) Borrower shall have paid to Administrative Agent the assignment fee specified in Section 10.5;

(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in Matured LC Obligations, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.4) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or Borrower (in the case of all other amounts);

(iii) (A) in the case of any such assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignees shall have agreed to, and shall be sufficient (together with all other consenting Lenders) to cause the adoption of, the applicable departure, waiver or amendment of the Loan Documents and (B) in the case of any such assignment resulting from a claim for compensation under Section 3.2 or payments required to be made pursuant to Section 3.5, such assignment will result in a reduction in such compensation or payments thereafter and (C) in the case of any assignment due to illegality, such assignee can fund and maintain Eurodollar Loans; and

(iv) such assignment does not conflict with applicable law.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling Borrower to require such assignment and delegation cease to apply. In connection with any such replacement, if any such Lender does not execute and deliver to Administrative Agent a duly executed assignment specified in Section 10.5 reflecting such replacement within five (5) Business Days of the date on which the assignee Lender executes and delivers such assignment to such Lender, then such Lender shall be deemed to have executed and delivered such assignment without any action on the part of such Lender.

(a) occurrence of any Material Adverse Change,

(b) the occurrence of any Default,

(c) the acceleration of the maturity of any Indebtedness owed by any Restricted Person or of any default by any Restricted Person under any indenture, mortgage, agreement, contract or other instrument to which any of them is a party or by which any of them or any of their properties is bound, if such acceleration or default could reasonably be expected to cause a Material Adverse Change,

(d) the occurrence of any Termination Event,

(e) any claim of $10,000,000 or more, any notice of potential liability under any Environmental Laws which might exceed such amount, or any other material adverse claim asserted against any Restricted Person or with respect to any Restricted Person’s properties, and

Upon the occurrence of any of the foregoing Restricted Persons will take all necessary or appropriate steps to remedy promptly any such Material Adverse Change, Default, acceleration, default or Termination Event, to protect against any such adverse claim, to defend any such suit or proceeding, and to resolve all controversies on account of any of the foregoing. Borrower will also notify Administrative Agent and Administrative Agent’s counsel in writing at least twenty Business Days prior to the date that any Restricted Person changes its name or the location of its chief executive office or principal place of business or the place where it keeps its books and records, furnishing with such notice any necessary financing statement amendments or requesting Administrative Agent and its counsel to prepare the same.

Section 6.5 Maintenance of Properties. Each Restricted Person will maintain, preserve, protect, and keep all Collateral and all other property used or useful in the conduct of its business in good condition, and will from time to time make all repairs, renewals and replacements needed to enable the business and operations carried on in connection therewith to be promptly and advantageously conducted at all times.

Section 6.6 Maintenance of Existence and Qualifications. Each Restricted Person will maintain and preserve its existence and its rights and franchises in full force and effect and will qualify to do business in all states or jurisdictions where required by applicable Law, except where the failure so to qualify will not cause a Material Adverse Change. The foregoing shall not restrict (i) any merger or consolidation permitted by Section 7.4 or (ii) the liquidation or dissolution of any Subsidiary if Borrower determines in good faith that such liquidation or dissolution is in the best interests of Borrower and is not materially disadvantageous to the Lenders.

Each Restricted Person may, however, delay paying or discharging any of the foregoing so long as (i) it is in good faith contesting the validity thereof by appropriate proceedings and has set aside on its books adequate reserves therefor or (ii) the nonpayment or nondischarge could not reasonably be expected to cause a Material Adverse Change.

Section 6.8 Insurance.

(a) Each Restricted Person shall at all times maintain (at its own expense) insurance for its property in accordance with the Insurance Schedule in at least such amounts, with at least such limitations on deductibles, and against such risks, in such form and with such financially sound and reputable insurers as shall be reasonably satisfactory to Administrative Agent from time to time. Each Restricted Person shall at all times maintain insurance against its liability for injury to persons or property in accordance with the Insurance Schedule, which insurance shall be by financially sound and reputable insurers.

(b) All insurance policies shall be modified or endorsed as necessary to (A) name Administrative Agent as loss payee on policies insuring loss or damage of Collateral and as additional insured on policies insuring against liability for injury to persons or property, and (B) prevent any expiration, or cancellation of the coverage provided by such policies without at least thirty (30) days prior written notice to Administrative Agent by the insurer. Each Restricted Person shall, if so requested by Administrative Agent, deliver to Administrative Agent original or duplicate policies of such insurance and, as often as Administrative Agent may reasonably request, a report of a reputable insurance broker with respect to such insurance. Administrative Agent shall, upon the occurrence and during the continuance of an Event of Default, have the right to collect and Borrower hereby assigns to Administrative Agent for the benefit of Lenders (and hereby agrees to cause each other Restricted Person to assign), any and all moneys that may become payable under any such policies of insurance by reason of damage, loss or destruction of any of the Collateral or any part thereof and to apply such moneys to the payment of the Obligations as herein provided. Reimbursement under any liability insurance maintained by Restricted Persons pursuant to this Section 6.8 may be paid directly to the Person who has incurred the liability covered by such insurance.

Section 6.9 Performance on Borrower’s Behalf. If any Restricted Person fails to pay any taxes, insurance premiums, expenses, attorneys’ fees or other amounts it is required to pay under any Loan Document, Administrative Agent may pay the same. Borrower shall immediately reimburse Administrative Agent for any such payments and each amount paid by Administrative Agent shall constitute an Obligation owed hereunder which is due and payable on the date such amount is paid by Administrative Agent.

Section 6.10 Interest. Borrower hereby promises to each Lender Party to pay interest at the Default Rate applicable to Base Rate Loans on all Obligations (including Obligations to pay fees or to reimburse or indemnify any Lender) which Borrower has in this Agreement promised to pay to such Lender Party and which are not paid when due. Such interest shall accrue from the date such Obligations become due until they are paid.

Section 6.11 Compliance with Agreements and Law. Each Restricted Person will perform all material obligations it is required to perform under the terms of each indenture, mortgage, deed of trust, security agreement, lease, franchise, agreement, contract or other instrument or obligation to which it is a party or by which it or any of its properties is bound, except when failure to do so could not reasonably be expected to cause a Material Adverse Change. Each Restricted Person will conduct its business and affairs in compliance with all Laws applicable thereto and will maintain in good standing all licenses that may be necessary or appropriate to carry on its business, except when failure to do so could not reasonably be expected to cause a Material Adverse Change.

Section 6.12 Environmental Matters; Environmental Reviews.

(a) Except in each case where failure to do so could not reasonably be expected to cause a Material Adverse Change, each Restricted Person will comply in all material respects with all Environmental Laws now or hereafter applicable to such Restricted Person, as well as all contractual obligations and agreements with respect to environmental remediation or other environmental matters, and shall obtain, at or prior to the time required by applicable Environmental Laws, all environmental, health and safety permits, licenses and other authorizations necessary for its operations and will maintain such authorizations in full force and effect. Except in each case where failure to do so could not reasonably be expected to cause a Material Adverse Change, no Restricted Person will do anything or permit anything to be done which will subject any of its properties to any remedial obligations under, or result in noncompliance with applicable permits and licenses issued under, any applicable Environmental Laws, assuming disclosure to the applicable governmental authorities of all relevant facts, conditions and circumstances. Upon Administrative Agent’s reasonable request, at any time and from time to time, Borrower will provide at its own expense an environmental inspection of any of the Restricted Persons’ material real properties and audit of their environmental compliance procedures and practices, in each case from an engineering or consulting firm reasonably acceptable to Administrative Agent. Administrative Agent and Lenders will use their best efforts to protect any attorney client privilege that exists with respect to reports or audits prepared by such engineers or consultants.

(b) Borrower will promptly furnish to Administrative Agent all written notices of violation, orders, claims, citations, complaints, penalty assessments, suits or other proceedings received by any Restricted Person, or of which Borrower otherwise has notice, pending or threatened against any Restricted Person by any Governmental Authority with respect to any alleged violation of or non-compliance with any Environmental Laws or relating to potential responsibility with respect to any investigation or clean-up of Hazardous Material at any location, in each case which involves a claim or liability in excess of $10,000,000.

Section 6.13 Evidence of Compliance. Each Restricted Person will furnish to each Lender at such Restricted Person’s or Borrower’s expense all evidence which Administrative Agent from time to time reasonably requests in writing as to the accuracy and validity of or compliance with all representations, warranties and covenants made by any Restricted Person in the Loan Documents, the satisfaction of all conditions contained therein, and all other matters pertaining thereto.

Section 6.14 Bank Accounts; Offset. To secure the repayment of the Obligations Borrower hereby grants to each Lender Party a security interest, a lien, and a right of offset, each of which shall be in addition to all other interests, liens, and rights of any Lender Party at common Law, under the Loan Documents, or otherwise, and each of which shall be upon and against (a) any and all moneys, securities or other property (and the proceeds therefrom) of Borrower now or hereafter held or received by or in transit to any Lender Party from or for the account of Borrower, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all deposits (general or special, time or demand, provisional or final) of Borrower with any Lender Party, and (c) any other credits and claims of Borrower at any time existing against any Lender Party, including claims under certificates of deposit. At any time and from time to time after the occurrence of any Event of Default, each Lender Party is hereby authorized to foreclose upon, or to offset against the Obligations then due and payable (in either case without notice to Borrower), any and all items hereinabove referred to; provided, that in the event that any Impacted Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to Administrative Agent for further application in accordance with the provisions of Section 2.19 and, pending such payment, shall be segregated by such Impacted Lender from its other funds and deemed held in trust for the benefit of Administrative Agent and the Lenders, and (y) the Impacted Lender shall provide promptly to Administrative Agent a statement describing in reasonable detail the Obligations owing to such Impacted Lender as to which it exercised such right of setoff. The remedies of foreclosure and offset are separate and cumulative, and either may be exercised independently of the other without regard to procedures or restrictions applicable to the other.

Section 6.15 Guaranties of Borrower’s Subsidiaries. Each Domestic Subsidiary of Borrower that is a Material Subsidiary now existing or created, acquired or coming into existence after the date hereof shall, promptly upon request by Administrative Agent, execute and deliver to Administrative Agent an absolute and unconditional guaranty of the timely repayment of the Obligations and the due and punctual performance of the obligations of Borrower hereunder, which guaranty shall be satisfactory to Administrative Agent in form and substance. Each such Domestic Subsidiary of Borrower that is a Material Subsidiary existing on the date hereof shall duly execute and deliver such a guaranty prior to the making of any Loan hereunder. Borrower will cause each such Domestic Subsidiary to deliver to Administrative Agent, simultaneously with its delivery of such a guaranty, written evidence reasonably satisfactory to Administrative Agent and its counsel that such Domestic Subsidiary has taken all company action necessary to duly approve and authorize its execution, delivery and performance of such guaranty and any other documents which it is required to execute.

Section 6.16 Pledge of Stock of Foreign Subsidiaries. Borrower shall execute and deliver to Administrative Agent (and shall cause each Restricted Person to execute and deliver to Administrative Agent) a pledge agreement covering sixty-six percent (66%) of its Equity Interest

in each Foreign Subsidiary of Borrower that is a Material Subsidiary now existing or created, acquired or coming into existence after the date hereof and securing the Obligations, in form and substance acceptable to Administrative Agent. Borrower shall also deliver to Administrative Agent all certificates (or other evidence acceptable to Administrative Agent) evidencing Borrower’s Equity Interest in such Foreign Subsidiary which shall be duly endorsed or accompanied by stock powers executed in blank (as applicable) as Administrative Agent shall reasonably deem necessary or appropriate to grant, evidence and perfect a first priority Lien in Borrower’s Equity Interest in such Foreign Subsidiary.

Section 6.17 Collateral.

(a) At all times the Secured Obligations shall be secured by first and prior Liens (subject only to Permitted Liens) covering and encumbering (i) not less than the Minimum Collateral Amount, and all cogeneration facilities and transportation and gathering systems owned by any Restricted Person used in connection with the production and development of the Mineral Interests included therein, (ii) all of the issued and outstanding Equity Interest of each Subsidiary of Borrower owned by any Restricted Person subject to the limitation with respect to Foreign Subsidiaries set forth in Section 6.16, and (iii) all other personal property of the Restricted Persons that can be perfected by the filing of a financing statement under the UCC (excluding filings in the real property records), except for the Excluded Property. On the Closing Date, Borrower and its Subsidiaries shall deliver to Administrative Agent for the ratable benefit of each Lender and SG, Security Documents covering the foregoing, each in form and substance acceptable to Administrative Agent.

(b) To the extent necessary to comply with the first sentence of Section 6.17(a), contemporaneously with the effectiveness of the Borrowing Base on each Determination Date (or such longer period of time as agreed to by Administrative Agent), Borrower and its Subsidiaries shall execute and deliver to Administrative Agent, for the ratable benefit of each Lender and SG, Security Documents and financing statements in form and substance acceptable to Administrative Agent and duly executed by Borrower and any such Subsidiary (as applicable) together with such other assignments, conveyances, amendments, agreements and other writings (each duly authorized and executed) as Administrative Agent shall reasonably deem necessary or appropriate to grant, evidence and perfect the Liens required by this Section 6.17. In addition, contemporaneously with each such effectiveness of the Borrowing Base, Borrower and its Subsidiaries shall deliver to Administrative Agent favorable title information, title opinions or updates of title opinions in form, substance and authorship reasonably satisfactory to Administrative Agent with respect to the properties described in this Section 6.17 so that Administrative Agent shall have received, together with title information previously delivered to Administrative Agent, satisfactory title information on not less than the Minimum Collateral Amount and confirming that such Restricted Person has good and defensible title to such properties and interests, free and clear of all Liens other than Permitted Liens; provided so long as no Default has occurred that is continuing, additional title opinions or updates of title opinions shall not be required to be so delivered with respect to Borrowing Base Properties for which satisfactory title information was previously delivered to Administrative Agent.

(c) Borrower also agrees to deliver to Administrative Agent from time to time upon the request of Administrative Agent favorable title information, title opinions or updates of title

opinions in form, substance and authorship reasonably satisfactory to Administrative Agent with respect to the properties described in this Section 6.17 so that Administrative Agent shall have received, together with title information previously delivered to Administrative Agent, satisfactory title information on not less than the Minimum Collateral Amount and confirming that such Restricted Person has good and defensible title to such properties and interests, free and clear of all Liens other than Permitted Liens.

(d) If Borrower has provided title information under Section 6.17(c), Borrower shall, within 45 days of notice from Administrative Agent (or such longer period of time agreed to by Administrative Agent) that title defects or exceptions exist with respect to Borrowing Base Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 5.17 raised by such information, (ii) substitute acceptable mortgaged properties with no title defects or exceptions except for Permitted Liens having an equivalent value, or (iii) deliver title information in form and substance acceptable to Administrative Agent so that Administrative Agent shall have received, together with title information previously delivered to Administrative Agent, satisfactory title information on not less than the Minimum Collateral Amount.

(e) If Borrower is unable to cure any title defect requested by Administrative Agent or Lenders to be cured within the 45-day period described in Section 6.17(d) or Borrower does not comply with the requirements to provide acceptable title information covering not less than the Minimum Collateral Amount, such default shall not be a Default, but instead Administrative Agent and/or Required Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by Administrative Agent or Lenders. To the extent that Administrative Agent or Required Lenders are not satisfied with title to any Borrowing Base Property after such 45-day period has elapsed, the Borrowing Base shall be reduced by an amount equal to the engineered Borrowing Base value of such Borrowing Base Property (as determined by Administrative Agent in its sole and absolute discretion). This new Borrowing Base shall become effective immediately after receipt of such notice, and Borrower must prepay the Obligations in an aggregate amount at least equal to any Borrowing Base Deficiency resulting from the effectiveness of such new Borrowing Base (or, if the Loans have been paid in full, pay to LC Issuer Cash Collateral as required by Section 2.16(a)) pursuant to the payment options set forth in Section 2.7(a)(i) and 2.7(a)(ii). No provision of this Section 6.17 shall be deemed or construed to limit or modify the rights of Administrative Agent and Lenders under Section 2.9(b).

Section 6.18 Agreement to Deliver Security Documents. Borrower agrees to deliver and to cause each other Restricted Person to deliver to further secure the Secured Obligations, whenever requested by Administrative Agent in its reasonable discretion, deeds of trust, mortgages, chattel mortgages, security agreements, financing statements and other Security Documents in form and substance satisfactory to Administrative Agent for the purpose of (a) granting, confirming, and perfecting first and prior liens or security interests in any real or personal property which is at such time Collateral or which was required or intended to be Collateral pursuant to this Agreement or any Security Document previously executed and not then released by Administrative Agent, and (b) maintaining compliance with all applicable Laws, including those of any applicable Indian tribe, the Bureau of Indian Affairs, and the U.S. Bureau

of Land Management. Each Restricted Person hereby authorizes Administrative Agent to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the collateral describing the Collateral as “all assets” without the signature of any Restricted Person. Furthermore, Borrower agrees to deliver and to cause each other Restricted Person to deliver, whenever requested by Administrative Agent upon the occurrence and during the continuance of an Event of Default, transfer orders or letters in lieu thereof with respect to the production and proceeds of production from the Collateral, in form and substance satisfactory to Administrative Agent.

Section 6.19 Production Proceeds. Notwithstanding that, by the terms of the various Security Documents, Restricted Persons are and will be assigning to Administrative Agent and Lenders all of the “Production Proceeds” (as defined therein) accruing to the property covered thereby, so long as no Event of Default has occurred Restricted Persons may continue to receive from the purchasers of production all such Production Proceeds, subject, however, to the Liens created under the Security Documents, which Liens are hereby affirmed and ratified. Upon the occurrence of an Event of Default, Administrative Agent and Lenders may exercise all rights and remedies granted under the Security Documents subject to the terms thereof, including the right to obtain possession of all Production Proceeds then held by Restricted Persons or to receive directly from the purchasers of production all other Production Proceeds. In no case shall any failure, whether intentioned or inadvertent, by Administrative Agent or 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 Documents, nor shall any release of any Production Proceeds by Administrative Agent or Lenders to Restricted Persons constitute a waiver, remission, or release of any other Production Proceeds or of any rights of Administrative Agent or Lenders to collect other Production Proceeds thereafter.

Section 6.20 Mortgaged Property Covenants. Each Restricted Person will carry out its sales of production, will operate the Mineral Interests, and will otherwise deal with the Mineral Interests and the production therefrom, in such a way that the representations and warranties in Section 5.18 through 5.20 remain true and correct at, and as of, all times that this Agreement is in effect (and not just at, and as of, the times such representations and warranties are made).

Administrative Agent shall have no responsibility to determine the existence or amount of Lender Hedging Obligations and may reserve from the application of amounts under this Section amounts distributable in respect of Lender Hedging Obligations until it has received evidence satisfactory to it of the existence and amount of such Lender Hedging Obligations.

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose Administrative Agent to liability or that is contrary to any Loan Document or applicable law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as Administrative Agent or any of its Affiliates in any capacity.

Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 10.1 and 8.2) or (ii) in the absence of its own gross negligence or willful misconduct. Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to Administrative Agent by Borrower, a Lender or LC Issuer.

Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to Administrative Agent.

Section 9.3 Reliance by Administrative Agent. Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or LC Issuer, Administrative Agent may presume that such condition is satisfactory to such Lender or LC Issuer unless Administrative Agent shall have received notice to the contrary from such Lender or LC Issuer prior to the making of such Loan or the issuance of such Letter of Credit.

Administrative Agent may consult with legal counsel (who may be counsel for Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 9.4 Non-Reliance on Administrative Agent and Other Lenders. Each Lender and LC Issuer and SG acknowledges that it has, independently and without reliance upon Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and LC Issuer also acknowledges that it will, independently and without reliance upon Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 9.5 Rights as a Lender. The Person serving as Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with Borrower or any Subsidiary or other Affiliate thereof as if such Person were not Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 9.6 Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it shall, whether through the exercise of rights under Security Documents or rights of banker’s lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it, taking into account all distributions made by Administrative Agent under Section 3.1, and such payment causes such Lender Party to have received more than it would have received had such payment been received by Administrative Agent and distributed pursuant to Section 3.1, then (a) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Lender Parties to share all payments as provided for in Section 3.1, and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that Administrative Agent and all Lender Parties share all payments of Obligations as provided in Section 3.1; provided, however, that nothing herein contained shall in any way affect the right of any Lender Party to obtain payment (whether by exercise of rights of banker’s lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any and all rights of banker’s lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this section is thereafter recovered from the seller under this section which received the same, the purchase provided for in this section shall be deemed to have been rescinded to the extent of such recovery, together

with interest, if any, if interest is required pursuant to the order of a Governmental Authority order to be paid on account of the possession of such funds prior to such recovery.

Section 9.7 Investments. Whenever Administrative Agent in good faith determines that it is uncertain about how to distribute to Lender Parties any funds which it has received, or whenever Administrative Agent in good faith determines that there is any dispute among Lender Parties about how such funds should be distributed, Administrative Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Administrative Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Administrative Agent is otherwise required to invest funds pending distribution to Lender Parties, Administrative Agent shall invest such funds pending distribution; all interest on any such Investment shall be distributed upon the distribution of such Investment and in the same proportion and to the same Persons as such Investment. All moneys received by Administrative Agent for distribution to Lender Parties (other than to the Person who is Administrative Agent in its separate capacity as a Lender Party) shall be held by Administrative Agent pending such distribution solely as Administrative Agent for such Lender Parties, and Administrative Agent shall have no equitable title to any portion thereof.

Section 9.8 Resignation of Administrative Agent. Administrative Agent may at any time give notice of its resignation to the Lenders, LC Issuer, SG and Borrower. Upon receipt of any such notice of resignation, Required Lenders shall have the right, in consultation with Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and LC Issuer, appoint a successor Administrative Agent meeting the qualifications set forth above provided that if Administrative Agent shall notify Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any Collateral held by Administrative Agent on behalf of the Lenders or LC Issuer under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such Collateral until such time as a successor Administrative Agent is appointed) and (2) all payments, communications and determinations provided to be made by, to or through Administrative Agent shall instead be made by or to each Lender and LC Issuer directly, until such time as Required Lenders appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 10.4 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions

taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

Any resignation by Xxxxx Fargo as Administrative Agent pursuant to this Section shall also constitute its resignation as Issuer and Swing Line Lender. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring LC Issuer and Swing Line Lender, (ii) the retiring LC Issuer and Swing Line Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (iii) the successor LC Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring LC Issuer to effectively assume the obligations of the retiring LC Issuer with respect to such Letters of Credit.

Section 9.9 Delegation of Duties. Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by Administrative Agent. Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent

Section 9.10 No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Joint Bookrunners, the Lead Arranger, the Co-Syndication Agents, or the Co-Documentation Agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as Administrative Agent, a Lender or LC Issuer hereunder.

Section 9.11 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Restricted Person, Administrative Agent (irrespective of whether the principal of any Loan or LC Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether Administrative Agent shall have made any demand on Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, LC Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of Lenders, LC Issuer and Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of Lenders, LC Issuer and Administrative Agent and their respective agents and counsel and all other amounts due Lenders, LC Issuer and Administrative Agent under Sections 2.5 and 10.4) allowed in such judicial proceeding; and

Nothing contained herein shall be deemed to authorize Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or LC Issuer any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

Section 9.12 Guaranty Matters.

ARTICLE X - Miscellaneous

Section 10.1 Waivers and Amendments; Acknowledgments.

(a) Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Lender in exercising any right, power or remedy which such Lender Party may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by any Lender Party of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this section, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Restricted Person shall in any case of itself entitle any Restricted Person to any other or further notice or demand in similar or other circumstances. This Agreement and the other Loan Documents set forth the entire understanding between the parties hereto with respect to the transactions contemplated herein and therein and supersede all prior discussions and understandings with respect to the subject matter hereof and thereof, and no waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective against any party hereto unless the same is in writing and signed by (i) if such party is Borrower, by Borrower, (ii) if such party is Administrative Agent, the Swing Line Lender or LC Issuer, by such party, and (iii) if such party is a Lender, by such Lender or by Administrative Agent on behalf of Lenders with the written consent of Majority Lenders (which consent has already been given as to the termination of the Loan Documents as provided in Section 10.9). Notwithstanding the foregoing or anything to the contrary herein, Administrative Agent shall not, without the prior consent of each individual Lender, execute and deliver on behalf of such Lender any waiver or amendment which would: (1) waive any of the conditions specified in Section 4.1 (provided that Administrative Agent may in its discretion withdraw any request it has made under Section 4.1(a)), (2) increase the Commitment of such Lender, (3) reduce any fees payable to such Lender hereunder, or the principal of, or interest on, such Lender’s Note, (4) postpone any date fixed for any payment of any such fees, principal or interest (other than in respect of amendments to the defined terms “Liquidity Test” or “Leverage Test”, which amendments shall be valid and effective against each Lender if in writing and signed by such Lender or by Administrative Agent on behalf of Lenders with the written consent of Majority Lenders), (5) amend the definition herein of “Majority Lenders”, “Required Lenders”, or “Supermajority Lenders” or otherwise change the aggregate amount of Percentage Shares which is required for Administrative Agent, Lenders or any of them to take any particular action under the Loan Documents, (6) amend the definition of “Maximum Credit Amount” to mean an amount higher than $2,000,000,000, (7) release Borrower from its obligation to pay such Lender’s Note, or any Guarantor from its guaranty of such payment, (8) release all or substantially all of the Collateral, except for such releases relating to sales or dispositions of property permitted by the Loan Documents, or (9) amend this Section 10.1(a). Notwithstanding anything to the contrary herein, no Impacted Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or

consent that by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the applicable Lenders other than Impacted Lenders), except that (x) the Commitment of any Impacted Lender may not be increased or extended nor the principal owing to such Impacted Lender reduced without the consent of such Lender and (y) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Impacted Lender more adversely than other affected Lenders shall require the consent of such Impacted Lender. Notwithstanding the foregoing or anything to the contrary herein, Administrative Agent shall not, without the prior consent of SG, execute and deliver on behalf of SG or any of the Lenders any waiver or amendment which would cause the SG Money Market Facility to cease to constitute Secured Obligations or would otherwise cause the Indebtedness evidenced by such SG Money Market Facility to no longer receive the benefit of the Liens granted in the Collateral pursuant to the Security Documents on the priority basis set forth in Section 8.3 or would change the order of payment set forth in Section 8.3. SG shall be an intended third party beneficiary of the provisions of the preceding sentence and shall be entitled to enforce such provisions hereunder.

Borrower hereby represents, warrants, acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Loan Documents to which it is a party, (ii) it has made an independent decision to enter into this Agreement and the other Loan Documents to which it is a party, without reliance on any representation, warranty, covenant or undertaking by Administrative Agent or any Lender Party, whether written, oral or implicit, other than as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iii) there are no representations, warranties, covenants, undertakings or agreements by any Lender Party as to the Loan Documents except as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iv) no Lender Party has any fiduciary obligation toward Borrower with respect to any Loan Document or the transactions contemplated thereby, (v) the relationship pursuant to the Loan Documents between Borrower and the other Restricted Persons, on one hand, and each Lender Party, on the other hand, is and shall be solely that of debtor and creditor, respectively, (vi) no partnership or joint venture exists with respect to the Loan Documents between any Restricted Person and any Lender Party, (vii) Administrative Agent is not Borrower’s Administrative Agent, but Administrative Agent for Lenders, (viii) should a Default occur or exist, each Lender Party will determine in its sole discretion and for its own reasons what remedies and actions it will or will not exercise or take at that time, (ix) without limiting any of the foregoing, Borrower is not relying upon any representation or covenant by any Lender Party, or any representative thereof, and no such representation or covenant has been made, that any Lender Party will, at the time of a Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under the Loan Documents with respect to any such Default or any other provision of the Loan Documents, and (x) all Lender Parties have relied upon the truthfulness of the acknowledgments in this section in deciding to execute and deliver this Agreement and to become obligated hereunder.

Person (including Borrower or any of its Affiliates) ever alleges such gross negligence or willful misconduct by any Lender Party, the indemnification provided for in this section shall nonetheless be paid upon demand, subject to later adjustment or reimbursement, until such time as a court of competent jurisdiction enters a final judgment as to the extent and effect of the alleged gross negligence or willful misconduct. As used in this section the term “Lender Party” shall refer not only to each Person designated as such in Section 1.1 but also to each director, officer, Administrative Agent, agent, advisor, trustee, attorney, employee, representative and Affiliate of or for such Person.

Section 10.5 Successors and Assigns; Assignments.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that neither Borrower nor any other Restricted Person may assign or otherwise transfer any of its rights or obligations under any Loan Document without the prior written consent of Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans (including for purposes of this Section 10.5(b), participations in LC Obligations and in Swing Line Loans) at the time owing to it); provided that

(i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption Agreement with respect to such assignment is delivered to Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption Agreement, as of the Trade Date) shall not be less than $5,000,000;

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

100

(iii) any assignment of a Commitment must be approved by:

(A) Borrower, unless (1) the Person that is the proposed assignee is itself a Lender with a Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee), (2) a Default has occurred and is continuing, or (3) Borrower fails to communicate its approval or disapproval of such proposed assignment in writing to Administrative Agent within 10 Business Days after written notice thereof; and

(B) Administrative Agent, the Swing Line Lender and LC Issuer unless the Person that is the proposed assignee is itself a Lender with a Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee);

(iv) the parties to each assignment shall execute and deliver to Administrative Agent an Assignment and Assumption Agreement, together with a processing and recordation fee of $3,000, and the Eligible Assignee, if it shall not be a Lender, shall deliver to Administrative Agent an Administrative Questionnaire, in form satisfactory to Administrative Agent; and

(v) no such assignment shall be made (x) to Borrower or any of Borrower’s Affiliates or Subsidiaries, or (y) to any Impacted Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (y), or (z) to a natural person.

Subject to acceptance and recording thereof by Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption Agreement, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption Agreement, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption Agreement, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption Agreement covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Article III and Section 10.4 and Section 10.12 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section.

(c) Register. Administrative Agent, acting solely for this purpose as an agent of Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption Agreement delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and Borrower, Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all

101

purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, Borrower or Administrative Agent, sell participations to any Person (other than a natural person, an Impacted Lender, or Borrower or any of Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) Borrower, Administrative Agent and the Lenders and LC Issuer shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the fifth sentence of Section 10.1(a) that affects such Participant. Subject to subsection (e) of this Section, Borrower agrees that each Participant shall be entitled to the benefits of Article III to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 6.14 as though it were a Lender, provided such Participant agrees to be subject to Section 9.6 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Article III than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.5 unless Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of Borrower, to comply with Section 3.5(e) as though it were a Lender.

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

Section 10.6 Confidentiality. Administrative Agent and each Lender (each, a “Lending Party”) agrees to keep confidential any information furnished or made available to it by any Restricted Person pursuant to this Agreement that is marked confidential; provided that nothing herein shall prevent any Lending Party from disclosing such information (a) to any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee,

102

Administrative Agent, or advisor of any Lending Party or Affiliate of any Lending Party, (b) to any other Person if reasonably incidental to the administration of the credit facility provided herein, (c) as required by any Law, (d) upon the order of any court or administrative agency, (e) upon the request or demand of any Governmental Authority, (f) that is or becomes available to the public or that is or becomes available to any Lending Party other than as a result of a disclosure by any Lending Party prohibited by this Agreement, (g) in connection with any litigation to which such Lending Party or any of its Affiliates may be a party; provided that such Lending Party makes reasonable efforts to obtain from the applicable court protective orders or similar confidential procedures protecting such confidential information, (h) to the extent necessary in connection with the exercise of any right or remedy under this Agreement or any other Loan Document, and (i) subject to provisions substantially similar to those contained in this section, to (1) any actual or proposed Participant or assignee or (2) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to Borrower and its obligations.

Section 10.7 Governing Law; Submission to Process. Except to the extent that the law of another jurisdiction is expressly elected in a Loan Document, the Loan Documents shall be deemed contracts and instruments made under the laws of the State of California and shall be construed and enforced in accordance with and governed by the laws of the State of California and the laws of the United States of America, without regard to principles of conflicts of law. Borrower hereby irrevocably submits itself to the non-exclusive jurisdiction of the state and federal courts sitting in the Northern District of California for the United States District Court and agrees and consents that service of process may be made upon it in any legal proceeding relating to the Loan Documents or the Obligations by any means allowed under California or federal law.

Section 10.8 Limitation on Interest. Lender Parties, Restricted Persons and the other parties to the Loan Documents intend to contract in strict compliance with applicable usury Law from time to time in effect. In furtherance thereof such persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to provide for interest in excess of the maximum amount of interest permitted to be contracted for, charged, or received by applicable Law from time to time in effect. Neither any Restricted Person nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully contracted for, charged, or received under applicable Law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith.

Section 10.9 Termination; Limited Survival; Etc.

(a) In its sole and absolute discretion Borrower may at any time that no Obligations (other than those described in the third sentence of this Section 10.9(a)) are owing elect in a written notice delivered to Administrative Agent to terminate this Agreement. Upon receipt by Administrative Agent of such a notice, if no Obligations (other than those described in the third sentence of this Section 10.9(a)) are then owing, this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations

103

thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Restricted Person in any Loan Document, any Obligations under Sections 3.2 through Section 3.5, any obligations which any Person may have to indemnify or compensate any Lender Party and the provisions of Article IX and Section 10.1(a) with respect to any Security Documents which remain in effect after the termination of this Agreement, shall survive any termination of this Agreement or any other Loan Document. At the request and expense of Borrower, Administrative Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents. Administrative Agent is hereby authorized to execute all such instruments on behalf of all Lenders, without the joinder of or further action by any Lender.

(b) The benefit of the Security Documents and of the provisions of this Agreement relating to any collateral securing the Obligations shall also extend to and be available to Lender Counterparties on the basis described in the Loan Documents in respect of any Lender Hedging Obligations (to the extent limited in the definition thereof). No Lender or any Affiliate of a Lender shall have any voting rights under any Loan Document solely as a result of the existence of such Lender Hedging Obligations. No Lender or any Affiliate of a Lender, in its capacity as a Lender Counterparty, that obtains the benefits of any Security Document by virtue of the provisions hereof or of any Security Document or any Loan Document shall have any right to notice of any action or to consent to, direct or object to any action hereunder (including under Section 10.1) or under any other Loan Document or otherwise in respect of any Collateral (including the release or impairment of any Collateral) other than in its capacity as a Lender and, in such case, only to the extent expressly provided in the Loan Documents. Notwithstanding anything to the contrary contained herein or in any other Loan Document, no Lender Hedging Obligation shall be an Obligation hereunder.

Section 10.10 Severability. If any term or provision of any Loan Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable Law.

Section 10.11 Counterparts; Fax. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. This Agreement and the Loan Documents may be validly executed and delivered by facsimile or other electronic transmission.

SECTION 10.12 WAIVER OF JURY TRIAL, PUNITIVE DAMAGES, ETC. BORROWER AND EACH LENDER PARTY HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY (A) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED THEREWITH, BEFORE OR AFTER MATURITY; (B) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY “SPECIAL DAMAGES”, AS DEFINED

104

BELOW, (C) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR ADMINISTRATIVE AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (D) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION. AS USED IN THIS SECTION, “SPECIAL DAMAGES” INCLUDES ALL SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES (REGARDLESS OF HOW NAMED), BUT DOES NOT INCLUDE ANY PAYMENTS OR FUNDS WHICH ANY PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR DELIVER TO ANY OTHER PARTY HERETO. NO “ADMINISTRATIVE AGENT” REFERRED TO IN 10.4 ABOVE, AND NO “LENDER PARTY” REFERRED TO IN SECTION 10.4 ABOVE, SHALL BE LIABLE FOR ANY DAMAGES ARISING FROM THE USE BY UNINTENDED RECIPIENTS OF ANY INFORMATION OR OTHER MATERIALS DISTRIBUTED BY IT THROUGH TELECOMMUNICATIONS, ELECTRONIC OR OTHER INFORMATION TRANSMISSION SYSTEMS IN CONNECTION WITH THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

Section 10.13 USA PATRIOT Act Notice. Each Lender that is subject to the Act (as hereinafter defined) and Administrative Agent (for itself and not on behalf of any Lender) hereby notifies Borrower and each other Restricted Person that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001) (the “Act”)), it is required to obtain, verify and record information that identifies Borrower and each other Restricted Person, which information includes the name and address of Borrower and each other Restricted Person and other information that will allow such Lender or Administrative Agent, as applicable, to identify Borrower and each other Restricted Person in accordance with the Act.

Section 10.14 Ratification of Agreements. This Agreement amends and restates in its entirety the Existing Credit Agreement, together with the promissory notes made by Borrower thereunder. Borrower hereby agrees that the Indebtedness outstanding under the Existing Credit Documents and all accrued and unpaid interest thereon and all accrued and unpaid fees under the Existing Credit Documents shall be deemed to be outstanding under and governed by this Agreement.

Section 10.15 Amendment and Restatement. This Agreement amends and restates in its entirety the Existing Credit Agreement, and from and after the date hereof, the terms and provisions of the Existing Credit Agreement shall be superseded by the terms and provisions of this Agreement. Borrower hereby agrees that (i) the Existing Indebtedness, all accrued and unpaid interest thereon, and all accrued and unpaid fees under the Existing Credit Agreement shall be deemed to be Indebtedness of Borrower outstanding under and governed by this Agreement and (ii) all Liens securing the Existing Indebtedness shall continue in full force and effect to secure the Secured Obligations.
