Outstanding Amount of Obligations under Lender Hedging Agreements (it being understood that for purposes of this clause (iv) the Outstanding Amount of Obligations under Lender Hedging Agreements refers to payments owing in connection with an Early Termination Payment as defined in the 2002 Master Agreement form promulgated by the ISDA (or equivalent type payment obligation if some other form of Swap Contract is in effect)(as used in this Section 2.11(d)(iv), “ratable payment” means for any Lender (or Lender Affiliate, in the case of Lender Hedging Agreements), on any date of determination, that proportion which the Outstanding Amount of Loans and the Outstanding Amount of Obligations under Lender Hedging Agreements owed to such Lender (or Lender Affiliate, in the case of Lender Hedging Agreements) bears to the Outstanding Amount of Loans owed to all Lenders)(and Affiliates, in the case of Lender Hedging Agreements)); (v) to Cash Collateralize the Letters of Credit; and (vi) to the payment of the remaining Obligations, if any, in the order and manner the Required Lenders deem appropriate.”

(q)                                 Section 2.14(c)(vi)of the Credit Agreement is deleted in its entirety and the following is substituted therefor:

“A certificate of the Administrative Agent with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.”

(r)                                    Section 2.14(e)(v) of the Credit Agreement is deleted in its entirety and the following is substituted therefor:

“The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto and documents presented in connection with any drawing thereunder that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the L/C Issuer.”

(s)                                  Article II of the Credit Agreement is amended by adding a new Section 2.15 thereto to read in its entirety as follows:

Section 2.15  Optional NBB Revolving Credit Commitment.

“(a)  Request for Establishment of NBB Revolving Credit Commitment.  Provided no Default or Event of Default has occurred and is continuing, that the Borrower is in pro forma compliance with Section 7.15, that the Collateral Coverage Ratio is at least 3.5 to 1.0 (giving pro forma effect to any NBB Revolving Credit Borrowings actually requested), that the Borrower has delivered to the Administrative Agent a pro forma NBB Borrowing Certificate (reflecting what Swap Contracts are then in effect or will be in effect upon the Borrower’s providing any required margin requirements, the margin requirements under each such Swap Contract then in effect or proposed to be entered into and the amount of the proposed NBB Credit Extension which would be reflected on a NBB Borrowing Certificate delivered as of the end of the month in which the NBB Credit Extension is requested) and that the Administrative Agent consents thereto (which consent shall not be unreasonably withheld or delayed), upon notice to the Administrative Agent (which shall promptly notify the Lenders), the Borrower may request that a new revolving credit facility not subject to Borrowing Base availability but subject to meeting a Collateral Coverage Ratio of at least 3.5 to 1.0 (giving pro forma effect to any requested NBB Credit Extension thereunder) be established in a total amount not exceeding

12




$50,000,000 and which may be taken down in minimum increments of $10,000,000 (the amount of each such take down comprising a separate tranche under the NBB Revolving Credit Commitment); provided that any NBB Credit Extension shall be used solely for the purpose of enabling the Borrower to meet margin requirements under Swap Contracts; provided further that any NBB Credit Extension shall be secured pari passu with the Obligations.  At the time of sending such request to establish the NBB Revolving Credit Commitment, the Borrower (in consultation with the Administrative Agent) shall specify the time period within which each Lender is requested to respond (which shall in no event be less than 15 Business Days from the date of delivery of such notice to the Lenders).

(b)                                 Lender Elections to Participate in NBB Revolving Credit Commitment.  Each Lender shall notify the Administrative Agent within such time period whether or not it agrees to participate in the NBB Revolving Credit Commitment and, if so, what percentage of the NBB Revolving Credit Commitment it is willing to commit to fund.  Any Lender not responding within such time period shall be deemed to have declined to participate in the NBB Revolving Credit Commitment.  A Lender that agrees to participate in the NBB Revolving Credit Commitment shall have no obligation to participate in any subsequent requested increase in the NBB Revolving Credit Commitment or to participate in the same percentage as it participated in a prior NBB Revolving Credit Commitment.

(c)                                  Notification by Administrative Agent; Additional Lenders.  The Administrative Agent shall notify the Borrower and each Lender of the Lenders’ responses to the request made hereunder to participate in the NBB Revolving Credit Commitment.  To achieve the full amount of the requested NBB Revolving Credit Commitment (or any subsequent increase in the amount of the NBB Revolving Credit Commitment) and subject to the approval of the Administrative Agent (which approval shall not be unreasonably withheld or delayed), the Borrower may also invite additional Eligible Assignees to become Lenders pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel.  The Borrower shall have 30 calendar days from the date the Administrative Agent notifies the Borrower of the Lenders’ responses to the request to participate in the NBB Revolving Credit Commitment to invite additional Eligible Assignees and have them enter into a joinder agreement.

(d)                                 Effective Date and Allocations.  If the NBB Revolving Credit Commitment is established or increased in accordance with this Section, the Administrative Agent and the Borrower shall determine the effective date (the “NBB Revolving Credit Commitment Effective Date” and “NBB Revolving Credit Commitment Increase Effective Date”, respectively) and the final allocation for such established or increased NBB Revolving Credit Commitment.  The Administrative Agent shall promptly notify the Borrower and the Lenders of the final allocation of such established or increased NBB Revolving Credit Commitment and the NBB Revolving Credit Commitment Effective Date or NBB Revolving Credit Commitment Increase Effective Date, as applicable.

(e)                                  Conditions to Establishment/Increase of NBB Revolving Credit Commitment.  As a condition precedent to establishing or increasing the NBB Revolving Credit Commitment, the Borrower shall deliver to the Administrative Agent a pro forma NBB Borrowing Certificate and a certificate of each Loan Party dated as of the NBB Revolving Credit Commitment Effective Date or NBB Revolving Credit Commitment Increase Effective Date, as applicable (in sufficient copies for each Lender) signed by a

13




Responsible Officer of such Loan Party (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to the establishment or increase of the NBB Revolving Credit Commitment, and (ii) in the case of the Borrower, certifying that, before and after giving effect to such establishment or increase, (A) the representations and warranties contained in Article V and the other Loan Documents are true and correct on and as of the NBB Revolving Credit Commitment Effective Date or NBB Revolving Credit Commitment Increase Effective Date, as the case may be, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.15, the representations and warranties contained in Section 5.05(a) shall be deemed to refer to the most recent financial statements furnished pursuant to clauses (a) and (b), respectively, of Section 6.01, (B) no Default exists, (C) pro forma compliance with Section 7.15, and (D) that the Collateral Coverage Ratio is at least 3.5 to 1.0 giving pro forma effect to any actually requested NBB Credit Extension.

(f)                                    NBB Revolving Credit Loans.  Subject to and in reliance upon the terms, conditions, representations, and warranties in the Loan Documents (including each NBB Borrowing Certificate), each Lender that agrees to participate in the NBB Revolving Credit Commitment (or in any increase thereof) severally, but not jointly, agrees to make NBB Revolving Credit Loans to Borrower from time to time on any Business Day during the period from the NBB Revolving Credit Commitment Effective Date or NBB Revolving Credit Commitment Increase Effective Date, as the case may be, to the Maturity Date, in an aggregate amount not to exceed at any time outstanding the amount of such Lender’s NBB Pro Rata Share of one or more NBB Revolving Credit Borrowings not to exceed, when aggregated with the Outstanding Amount of NBB L/C Obligations, such Lender’s NBB Revolving Credit Commitment.  NBB Revolving Credit Borrowings may be repaid and reborrowed from time to time in accordance with the terms and provisions of the Loan Documents; provided that, each such NBB Revolving Credit Borrowing must occur on a Business Day and no later than the Business Day immediately preceding the Maturity Date; and provided further that at no time may the outstanding amount of NBB Revolving Credit Loans exceed the actual required margin requirements under Swap Contracts then in effect.  No Lender shall be obligated to make any NBB Revolving Credit Loan if the Outstanding Amount of all NBB L/C Obligations and all NBB Revolving Credit Loans would exceed the Aggregate NBB Revolving Credit Commitment.

(g)                                 Conflicting Provisions.  This Section shall supersede any provisions in Sections 2.12 or 10.01 to the contrary.”

(t)                                    Article II of the Credit Agreement is amended by adding a new Section 2.16 and a new Section 2.17 thereto to read in their entirety as follows:

“2.16                 NBB Letters of Credit.

(a)                                  The NBB Letter of Credit Commitment.

(i)                                     Subject to the terms and conditions set forth in Section 2.15, (A) the NBB L/C Issuer agrees, in reliance upon the agreements of the other Lenders having a NBB Revolving Credit Commitment set forth in this Section 2.16, (1) from time to time on any Business Day during the period from the NBB Revolving Credit Commitment

14




Effective Date until the NBB Letter of Credit Expiration Date, to issue NBB Letters of Credit for the account of the Borrower or any Guarantor, and to amend or renew NBB Letters of Credit previously issued by it, in accordance with subsection (b) below, and (2) to honor drawings under the NBB Letters of Credit; and (B) the Lenders having a NBB Revolving Credit Commitment severally agree to participate in NBB Letters of Credit issued for the account of the Borrower or any Guarantor; provided that the NBB L/C Issuer shall not be obligated to make any NBB L/C Credit Extension with respect to any NBB Letter of Credit, and no Lender having a NBB Revolving Credit Commitment shall be obligated to participate in any NBB Letter of Credit, if as of the date of such NBB L/C Credit Extension, (x) the Outstanding Amount of all NBB L/C Obligations and all NBB Revolving Credit Loans would exceed the Aggregate NBB Revolving Credit Commitment, or (y) the aggregate Outstanding Amount of the NBB Revolving Credit Loans of any Lender having a NBB Revolving Credit Commitment, plus such Lender’s NBB Pro Rata Share of the Outstanding Amount of all NBB L/C Obligations would exceed such Lender’s NBB Revolving Credit Commitment, or (z) the Outstanding Amount of the NBB L/C Obligations would exceed the NBB Letter of Credit Sublimit.  Within the foregoing limits, and subject to the terms and conditions hereof, the Borrower’s ability to obtain NBB Letters of Credit shall be fully revolving, and accordingly the Borrower may, during the foregoing period, obtain NBB Letters of Credit to replace NBB Letters of Credit that have expired or that have been drawn upon and reimbursed.

(ii)                                  The NBB L/C Issuer shall be under no obligation to issue any NBB Letter of Credit if:

(A)                              any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the NBB L/C Issuer from issuing such NBB Letter of Credit, or any Law applicable to the NBB L/C Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the NBB L/C Issuer shall prohibit, or request that the NBB L/C Issuer refrain from, the issuance of letters of credit generally or such NBB Letter of Credit in particular or shall impose upon the NBB L/C Issuer with respect to such NBB Letter of Credit any restriction, reserve or capital requirement (for which the NBB L/C Issuer is not otherwise compensated hereunder) not in effect on the Second Restatement Date, or shall impose upon the NBB L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Second Restatement Date and which the NBB L/C Issuer in good faith deems material to it;

(B)                                subject to Section 2.16(b)(iii), the expiry date of such requested NBB Letter of Credit would occur more than twelve months after the date of issuance or last renewal, unless the Required NBB Revolving Credit Lenders have approved such expiry date;

(C)                                the expiry date of such requested NBB Letter of Credit would occur after the NBB Letter of Credit Expiration Date, unless all the Lenders having a Revolving Credit Commitment have approved such expiry date;

(D)                               the issuance of such NBB Letter of Credit would violate one or more policies of the NBB L/C Issuer generally applicable to all borrowers; or

15




(E)                                 such NBB Letter of Credit is in a face amount less than $500,000, or is to be used for a purpose other than as described in Section 6.14 or is denominated in a currency other than Dollars.

(iii)                               The NBB L/C Issuer shall be under no obligation to amend any NBB Letter of Credit if (A) the NBB L/C Issuer would have no obligation at such time to issue such NBB Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such NBB Letter of Credit does not accept the proposed amendment to such NBB Letter of Credit.

(b)                                 Procedures for Issuance and Amendment of NBB Letters of Credit; NBB Evergreen Letters of Credit.

(i)                                     Each NBB Letter of Credit shall be issued or amended, as the case may be, upon the request of the Borrower delivered to the NBB L/C Issuer (with a copy to the Administrative Agent) in the form of a Letter of Credit Application, appropriately completed and signed by a Responsible Officer of the Borrower.  Such Letter of Credit Application must be received by the NBB L/C Issuer and the Administrative Agent not later than 11:00 a.m., New York time, at least two Business Days (or such later date and time as the NBB L/C Issuer may agree in a particular instance in its sole discretion) prior to the proposed issuance date or date of amendment, as the case may be.  In the case of a request for an initial issuance of a NBB Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the NBB L/C Issuer: (A) the proposed issuance date of the requested NBB Letter of Credit (which shall be a Business Day) and that such letter of credit is to be issued under the NBB Revolving Credit Commitment; (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as the NBB L/C Issuer may require.  In the case of a request for an amendment of any outstanding NBB Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the NBB L/C Issuer (A) the NBB Letter of Credit to be amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as the NBB L/C Issuer may require.

(ii)                                  Promptly after receipt of any Letter of Credit Application, the NBB L/C Issuer will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, the NBB L/C Issuer will provide the Administrative Agent with a copy thereof.  Upon receipt by the NBB L/C Issuer of confirmation from the Administrative Agent that the requested issuance or amendment is permitted in accordance with the terms hereof, then, subject to the terms and conditions hereof, the NBB L/C Issuer shall, on the requested date, issue a NBB Letter of Credit for the account of the Borrower or enter into the applicable amendment, as the case may be, in each case in accordance with the NBB L/C Issuer’s usual and customary business practices.  Immediately upon the issuance of each NBB Letter of Credit, each Lender having a NBB Revolving Credit Commitment for that particular tranche of the NBB Revolving Credit Commitment pursuant to which such NBB Letter of Credit is being issued shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the NBB

16




L/C Issuer a participation in such NBB Letter of Credit in an amount equal to the product of such Lender’s participation percentage in that tranche of the NBB Revolving Credit Commitment times the amount of such NBB Letter of Credit.

(iii)                               If the Borrower so requests in any applicable Letter of Credit Application, the NBB L/C Issuer may, in it sole and absolute discretion, agree to issue a NBB Letter of Credit that has automatic renewal provisions (each, an “NBB Evergreen Letter of Credit”); provided that any such NBB Evergreen Letter of Credit must permit the NBB L/C Issuer to prevent any such renewal at least once in each twelve-month period (commencing with the date of issuance of such NBB Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “NBB Nonrenewal Notice Date”) in each such twelve-month period to be agreed upon at the time such NBB Letter of Credit is issued.  Unless otherwise directed by the NBB L/C Issuer, the Borrower shall not be required to make a specific request to the NBB L/C Issuer for any such renewal.  Once an NBB Evergreen Letter of Credit has been issued, the Lenders having a NBB Revolving Credit Commitment for the tranche for which such NBB Evergreen Letter of Credit was issued shall be deemed to have authorized (but may not require) the NBB L/C Issuer to permit the renewal of such NBB Letter of Credit at any time to a date not later than the NBB Letter of Credit Expiration Date; provided, however, that the NBB L/C Issuer shall not permit any such renewal if it has received notice on or before the 5th Business Day immediately preceding the NBB Nonrenewal Notice Date (1) from the Administrative Agent that any of the Lenders having a NBB Revolving Credit Commitment for the tranche for which such NBB Evergreen Letter of Credit was issued has elected not to permit such renewal or (2) from any Lender having a NBB Revolving Credit Commitment for the tranche for which such NBB Evergreen Letter of Credit was issued stating that one or more of the applicable conditions specified in Section 4.02 or Section 4.04 is not then satisfied and directing the NBB L/C Issuer not to permit such renewal.  Notwithstanding anything to the contrary contained herein, the NBB L/C Issuer shall have no obligation to permit the renewal of any NBB Evergreen Letter of Credit at any time.

(iv)                              Promptly after its delivery of any NBB Letter of Credit or any amendment to a NBB Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the NBB L/C Issuer will also deliver to the Borrower and the Administrative Agent a true and complete copy of such NBB Letter of Credit or amendment.

(c)                                  Drawings and Reimbursements; Funding of Participations.

(i)                                     Upon any drawing under any NBB Letter of Credit, the NBB L/C Issuer shall notify the Borrower and the Administrative Agent thereof.   Not later than 11:00 a.m., New York time, on the date of any payment by the NBB L/C Issuer under a NBB Letter of Credit (each such date, an “NBB Honor Date”), the Borrower shall reimburse the NBB L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing.  If the Borrower fails to so reimburse the NBB L/C Issuer by such time, the Administrative Agent shall promptly notify each Lender having a NBB Revolving Credit Commitment for the tranche for which such NBB  Letter of Credit was issued of the NBB Honor Date, the amount of the unreimbursed drawing (the “NBB Unreimbursed Amount”), and such Lender’s participation in such NBB Letter of Credit (i.e., the amount equal to the product of such Lender’s participation percentage in that tranche of the NBB

17




Revolving Credit Commitment pursuant to which such NBB Letter of Credit was issued times the amount of such NBB Letter of Credit).  In such event, the Borrower shall be deemed to have requested a Borrowing of Base Rate Loans under the NBB Revolving Credit Commitment for the tranche for which such NBB Letter of Credit was issued to be disbursed on the NBB Honor Date in an amount equal to the NBB Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.03 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the Aggregate Revolving Credit Commitment for the tranche for which such NBB Letter of Credit was issued and the conditions set forth in Section 4.02 and Section 4.04 (other than the delivery of a NBB Borrowing Notice).  Any notice given by the NBB L/C Issuer or the Administrative Agent pursuant to this Section 2.16(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii)                                  Each Lender having a NBB Revolving Credit Commitment for the tranche for which such NBB Letter of Credit was issued (including the Lender acting as NBB L/C Issuer) shall upon any notice pursuant to Section 2.16(c)(i) make funds available to the Administrative Agent for the account of the NBB L/C Issuer at the Administrative Agent’s Office in an amount equal to its participation in such NBB Letter of Credit in an amount equal to the product of such Lender’s participation percentage in that tranche of the NBB Revolving Credit Commitment times the amount of such NBB Unreimbursed Amount not later than 11:00 a.m., New York time, on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.16(c)(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Loan under the NBB Revolving Credit Commitment for the related tranche to the Borrower in such amount.  The Administrative Agent shall remit the funds so received to the NBB L/C Issuer.

(iii)                               With respect to any NBB Unreimbursed Amount that is not fully refinanced by a Borrowing of Base Rate Loans because the conditions set forth in Section 4.02 or Section 4.04 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from the NBB L/C Issuer an NBB L/C Borrowing in the amount of the NBB Unreimbursed Amount that is not so refinanced, which NBB L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate.  In such event, each Lender’s payment to the Administrative Agent for the account of the NBB L/C Issuer pursuant to Section 2.16(c)(ii) shall be deemed payment in respect of its participation in such NBB L/C Borrowing and shall constitute an NBB L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.16.

(iv)                              Until each Lender having a NBB Revolving Credit Commitment for the tranche for which a NBB Letter of Credit was issued funds its NBB Revolving Credit Loan or NBB L/C Advance pursuant to this Section 2.16(c) to reimburse the NBB L/C Issuer for any amount drawn under any NBB Letter of Credit, interest in respect of such Lender’s proportionate share of such amount shall be solely for the account of the NBB L/C Issuer.

(v)                                 The obligation of each Lender having a NBB Revolving Credit Commitment to make NBB Revolving Credit Loans or NBB L/C Advances to reimburse

18




the NBB L/C Issuer for amounts drawn under NBB Letters of Credit, as contemplated by this Section 2.16(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the NBB L/C Issuer, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default or Event of Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing.  Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the NBB L/C Issuer for the amount of any payment made by the NBB L/C Issuer under any NBB Letter of Credit, together with interest as provided herein.

(vi)                              If any Lender having a NBB Revolving Credit Commitment fails to make available to the Administrative Agent for the account of the NBB L/C Issuer any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.16(c) by the time specified in Section 2.16(c)(ii), the NBB L/C Issuer shall be entitled to recover from such Lender (acting through the 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 NBB L/C Issuer at a rate per annum equal to the Federal Funds Rate from time to time in effect.  A certificate of the Administrative Agent with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

(d)                                 Repayment of Participations.

(i)                                     At any time after the NBB L/C Issuer has made a payment under any NBB Letter of Credit and has received from any Lender such Lender’s NBB L/C Advance in respect of such payment in accordance with Section 2.16(c), if the Administrative Agent receives for the account of the NBB L/C Issuer any payment related to such NBB Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of cash Collateral applied thereto by the Administrative Agent), or any payment of interest thereon, the Administrative Agent will distribute to such Lender an amount equal to the product of such Lender’s participation percentage in that tranche of the NBB Revolving Credit Commitment under which NBB Letter of Credit was issued times the amount of such payment) in the same funds as those received by the Administrative Agent.

(ii)                                  If any payment received by the Administrative Agent for the account of the NBB L/C Issuer pursuant to Section 2.16(c)(i) is required to be returned, each Lender having a NBB Revolving Credit Commitment for the related tranche shall pay to the Administrative Agent for the account of the NBB L/C Issuer an amount equal to the product of such Lender’s participation percentage in that tranche of the NBB Revolving Credit Commitment times the amount of such required returned payment on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect.

(e)                                  Obligations Absolute.  The obligation of the Borrower to reimburse the NBB L/C Issuer for each drawing under each NBB Letter of Credit, and to repay each NBB L/C Borrowing and each drawing under a NBB Letter of Credit that is refinanced by a Borrowing of NBB Revolving Credit Loans, shall be absolute, unconditional and

19




irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(i)                                     any lack of validity or enforceability of such NBB Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

(ii)                                  the existence of any claim, counterclaim, set-off, defense or other right that the Borrower may have at any time against any beneficiary or any transferee of such NBB Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the NBB L/C Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such NBB Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(iii)                               any draft, demand, certificate or other document presented under such NBB Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such NBB Letter of Credit;

(iv)                              any payment by the NBB L/C Issuer under such NBB Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such NBB Letter of Credit; or any payment made by the NBB L/C Issuer under such NBB Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such NBB Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law; or

(v)                                 any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, that might otherwise constitute a defense available to, or a discharge of, the Borrower.

The Borrower shall promptly examine a copy of each NBB Letter of Credit and each amendment thereto and documents presented in connection with any drawing thereunder that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the NBB L/C Issuer.  The Borrower shall be conclusively deemed to have waived any such claim against the NBB L/C Issuer and its correspondents unless such notice is given as aforesaid.

(f)                                    Role of L/C Issuer.  Each Lender having a NBB Revolving Credit Commitment and the Borrower agree that, in paying any drawing under a NBB Letter of Credit, the NBB L/C Issuer shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the NBB Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document.  No Agent-Related Person nor any of the respective correspondents, participants or assignees of the NBB L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required

NBB Revolving Credit Lenders, as applicable, (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any NBB Letter of Credit or Letter of Credit Application.  The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any NBB Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement.  No Agent-Related Person, nor any of the respective correspondents, participants or assignees of the NBB L/C Issuer, shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.16(e); provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the NBB L/C Issuer, and the NBB L/C Issuer may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by the NBB L/C Issuer’s willful misconduct or gross negligence or the NBB L/C Issuer’s willful failure to pay under any NBB Letter of Credit after the presentation to it by the beneficiary of a drawing strictly complying with the terms and conditions of a NBB Letter of Credit.  In furtherance and not in limitation of the foregoing, the NBB L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the NBB L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a NBB Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(g)                                 Cash Collateral.   Upon the request of the Administrative Agent, (i) if the NBB L/C Issuer has honored any full or partial drawing request under any NBB Letter of Credit and such drawing has resulted in a NBB L/C Borrowing, or (ii) if, as of the NBB Letter of Credit Expiration Date, any NBB Letter of Credit may for any reason remain outstanding and partially or wholly undrawn, or (iii) if at any time the Collateral Coverage Ratio is less than 3.5 to 1.0, the Borrower shall immediately Cash Collateralize the then Outstanding Amount of all NBB L/C Obligations (in an amount equal to such Outstanding Amount).  The Borrower hereby grants the Administrative Agent, for the benefit of the NBB L/C Issuer and the Lenders having a NBB Revolving Credit Commitment, a Lien on all such cash and deposit accounts at any Lender having a NBB Revolving Credit Commitment.

(h)                                 Applicability of ISP98.  Unless otherwise expressly agreed by the NBB L/C Issuer and the Borrower when a NBB Letter of Credit is issued, the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each NBB Letter of Credit.

(i)                                     NBB Letter of Credit Fees.  The Borrower shall pay to the Administrative Agent for the account of each Lender having a NBB Revolving Credit Commitment for a tranche for which a NBB  Letter of Credit was issued a NBB Letter of Credit fee for each NBB Letter of Credit issued under such tranche equal to the Applicable Rate times the actual daily undrawn amount under each NBB Letter of Credit issued under such tranche, with each such Lender receiving an amount equal to the

21




product of such Lender’s participation percentage in that tranche of the NBB Revolving Credit Commitment under which such NBB Letter of Credit was issued times the applicable NBB Letter of Credit fee.  Such fee for each NBB Letter of Credit shall be due and payable on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such NBB Letter of Credit, and on the NBB Letter of Credit Expiration Date.  If there is any change in the Applicable Rate during any quarter, the actual daily undrawn amount of each NBB Letter of Credit shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.

(j)                                     Fronting Fee and Documentary and Processing Charges Payable to NBB L/C Issuer.  The Borrower shall pay directly to the NBB L/C Issuer for its own account a fronting fee in an amount with respect to each NBB Letter of Credit issued equal to the greater of (i) $500 and (ii) ¼ of 1% calculated on the face amount thereof.   In addition, the Borrower shall pay directly to the NBB L/C Issuer for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the NBB L/C Issuer relating to letters of credit as from time to time in effect.  Such fees and charges are due and payable on demand and are nonrefundable.

(k)                                  Conflict with Letter of Credit Application.  In the event of any conflict between the terms hereof and the terms of any Letter of Credit Application, the terms hereof shall control.

2.17                        Pari Passu Lien Securing Lender Hedging Agreements.  All Obligations arising under the Loan Documents, including, without limitation, Obligations under this Agreement and Obligations under any Lender Hedging Agreement (but not Indebtedness of the Borrower or any MarkWest Inc. Subsidiary owing to any non-Lender or non-Lender Affiliate in connection with any Swap Contract), shall be secured  pari passu by the Collateral.”

(u)                                 Section 4.02 of the Credit Agreement is deleted and the following is substituted therefor:

4.02                 Conditions to all Loans each L/C Credit Extension and NBB L/C Credit Extension.  The obligation of each Lender to honor any Borrowing Notice and the obligation of the L/C Issuer to issue any Letter of Credit and the obligation of the NBB L/C Issuer to issue any NBB Letter of Credit is subject to the following conditions precedent:

(a)                                  The representations and warranties of the Loan Parties contained in Article V, or which are contained in any document furnished at any time under or in connection herewith, including, but not limited to the Collateral Documents, shall be true and correct in all material respects on and as of the date of such Loan is made, continued or converted, as applicable, or such Letter of Credit or NBB Letter of Credit is issued except to the extent that such representations and warranties specifically refer to an earlier date, in which case they shall be true and correct as of such earlier date.

(b)                                 Since the date of the last delivered financial statements, there has been no event or circumstance that has or could reasonably be expected to have a Material Adverse Effect.

(d)                                 The Administrative Agent and, if applicable, the L/C Issuer, and, if applicable the NBB L/C Issuer shall have received a Request for Credit Extension and, if applicable, a Letter of Credit Application in accordance with the requirements hereof.

(e)                                  The Administrative Agent shall have received, in form and substance reasonably satisfactory to it, such other assurances, certificates, documents or consents related to the foregoing as the Administrative Agent reasonably may require.
