          WHEREAS, the issuance of the Bay Gas LC for the account of Subsidiary Borrower and the making of Bay Gas Revolving Loans to Subsidiary Borrower will result in direct and substantial benefits to Guarantor;

          NOW, THEREFORE, in order to induce the Issuing Bank to issue and continue in effect the Bay Gas LC for the account of Subsidiary Borrower and to induce the Guaranteed Parties to make Loans and otherwise to extend and continue to extend credit to Subsidiary Borrower and other Subsidiaries of Guarantor hereafter, and in consideration of $10.00 and other good and valuable consideration received by Guarantor, Guarantor hereby declares and agrees:

          1. Guarantor hereby unconditionally and irrevocably guarantees to the Guaranteed Parties, and any transferee of any of the Guaranteed Obligations, the full and prompt payment when due of all Guaranteed Obligations and all costs, charges and expenses (including reasonable attorneys’ fees) incurred or sustained by the Guaranteed Parties in enforcing the obligations of Guarantor hereunder. If any portion of the Guaranteed Obligations is not paid when due, Guarantor hereby agrees to and will immediately pay same, without resort by the Guaranteed Parties to any other person or party. The obligation of Guarantor to the Guaranteed Parties hereunder is primary, absolute and unconditional. Any and all payments by Guarantor hereunder shall be made free and clear of, and without deduction for, any set-off, counterclaim, recoupment, or withholding so that, in each case, each Guaranteed Party will receive, after giving effect to any Taxes (other than taxes applicable to the Guaranteed Party of the types described in the definition of “ Excluded Taxes ” as set forth in the Credit Agreement), the full amount that it would otherwise be entitled to receive with respect to the Guaranteed Obligations (but without duplication of amounts for Taxes already included in the Guaranteed Obligations). Guarantor acknowledges and agrees that this is a guarantee of payment when due, and not of collection.

          2. This Guarantee is continuing in nature and shall be effective with respect to the full amount outstanding under all Guaranteed Obligations, now existing or hereafter made or extended, and notwithstanding (i) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or like proceeding relating to Guarantor or Subsidiary Borrower, or any action taken with respect to this Guarantee by any trustee or receiver, or by any court, in any such proceeding, (ii) any lack of validity or enforceability of the Credit Agreement or the other Loan Documents, or (iii) any other circumstance that might otherwise constitute a defense available to, or a discharge of, Guarantor. Guarantor acknowledges and agrees that the number and amounts of outstanding Guaranteed Obligations may fluctuate from time to time hereafter, and that Subsidiary Borrower may make payments to the Guaranteed Parties from time

to time hereafter. Guarantor expressly agrees that this Guarantee shall continue in full force and effect notwithstanding such fluctuations and payments, and whether or not any Guaranteed Obligations are outstanding at any particular time, until such time as all Guaranteed Obligations have been paid in full and any commitment of the Guaranteed Parties under the Credit Agreement has been terminated.

          3. Guarantor hereby waives notice of the Guaranteed Parties’ acceptance of this Guarantee and the creation, extension or renewal of any Loans or other Guaranteed Obligations. Guarantor hereby consents and agrees that, at any time or times, without notice to or further approval from Guarantor, and without in any way affecting the obligations of Guarantor hereunder, the Guaranteed Parties may, with or without consideration (i) release, compromise with, or agree not to sue, in whole or in part, Subsidiary Borrower or any other obligor, guarantor, endorser or surety on any Guaranteed Obligations, (ii) renew, extend, accelerate, or increase or decrease the principal amount of any Guaranteed Obligations, either in whole or in part, (iii) amend, waive, or otherwise modify any of the terms of any Guaranteed Obligations or of any Security Document or other undertaking of Subsidiary Borrower or any other obligor, endorser, guarantor or surety in connection with any Guaranteed Obligations, and (iv) apply any payment received from Subsidiary Borrower or from any other obligor, guarantor, endorser or surety on any Guaranteed Obligations to any of the liabilities of Subsidiary Borrower or of such other obligor, guarantor, endorser, or surety which the Guaranteed Parties may choose.

          4. Guarantor hereby consents and agrees that the Guaranteed Parties may at any time or times, either with or without consideration, surrender, release or receive any property or other collateral of any kind or nature whatsoever held by it or for its account securing any Guaranteed Obligations, or substitute any collateral so held by the Guaranteed Parties for other collateral of like or different kind, without notice to or further consent from Guarantor, and such surrender, receipt, release or substitution shall not in any way affect the obligations of Guarantor hereunder. The Guaranteed Parties shall have full authority to adjust, compromise, and receive less than the amount due upon any such collateral, and may enter into any accord and satisfaction agreement with respect to the same as the Guaranteed Parties may deem advisable without affecting the obligations of Guarantor hereunder. The Guaranteed Parties shall be under no duty to undertake to collect upon such collateral or any part thereof, and no Guarantor’s obligations hereunder shall be affected by the Guaranteed Parties’ alleged negligence or mistake in judgment in handling, disposing of, obtaining, or failing to collect upon or perfect a security interest in, any such collateral.
