Section 2.2    Amendment and Restatement of Section 9.2.5. Section 9.2.5 of the Credit Agreement is hereby amended and restated to read in its entirety as follows:

9.2.5    Dispositions. Make any Disposition other than an Excluded Disposition (other than Permitted Investments involving the sale or other Disposition of Collateral, which Permitted Investments involving the sale or other Disposition of Collateral shall be subject to this Section 9.2.5), except the following:

(a)    sales or other Dispositions of assets (other than Permitted Accounts Transactions and Sale and Leaseback Transactions) having an aggregate fair market value not to exceed during any Fiscal Year the greater of $15,000,000 or 1% of Consolidated Net Tangible Assets for the most recent Fiscal Year for which annual audited financial statements have been delivered to Agent in accordance with the terms hereof;

(b)    Sale and Leaseback Transactions involving Property not constituting Collateral (including, for the avoidance of doubt, metals or other elements, composites or alloys used as, or part of, a catalyst) with respect to assets having an aggregate fair market value, determined at the time of the consummation of each such transaction, not to exceed during any Fiscal Year the greater of $75,000,000 or 5% of Consolidated Net Tangible Assets for the most recent Fiscal Year for which annual audited financial statements have been delivered to the Agent in accordance with the terms hereof;

(c)    Dispositions of Hydrocarbons in connection with any Structured Hydrocarbon Supply Arrangement;

(d)    sales or other Dispositions of assets (other than Permitted Accounts Transactions) if (i) Availability (A) at all times during the 30-day period preceding such sale or other Disposition and (B) on the date of such sale or other Disposition and after giving effect thereto (including any reduction in the Borrowing Base to result therefrom), in each case, on a Pro Forma Basis, shall be greater than or equal to 15% of the Borrowing Base then in effect and (ii) if Availability as referred to in (i)(A) or (B) above is less than 22.5% of the Borrowing Base then in effect (which Availability under clause (i)(A) above shall be, for purposes of this clause (B) only, calculated on an average basis for such 30-day period), Borrower Agent shall have delivered to Agent a certificate demonstrating, based on adjustments made in good faith using reasonable assumptions, that, upon and after giving effect to such sale or other Disposition, the Fixed Charge Coverage Ratio on a Pro Forma Basis would be at least 1.0 to 1.0; and

(e)    Permitted Accounts Transactions;

provided, however, that, in connection with any sale or Disposition of Collateral (including, without limitation, any sale or other Disposition of Collateral which constitutes or is made in connection with a Permitted Investment but excluding any Permitted Accounts Transactions) and, except as stated in the proviso below, in connection with any sale or Disposition pursuant to Section 9.2.5(d):

(i)    Borrower Agent shall deliver to Agent, at least two Business Days prior to the consummation of each such sale or other Disposition which involves any Collateral, a then current Borrowing Base Certificate which gives effect thereto and such sale or other Disposition shall result in an immediate and automatic adjustment of the Borrowing Base to reflect such sale or other Disposition and, if necessary to ensure that the Revolver Usage does not exceed the Borrowing Base after giving effect thereto, Borrowers shall, prior to or concurrently with such consummation, repay the Obligations in an amount sufficient to eliminate such excess;

(ii)    at least 75% (or, in the case of any sale or other Disposition of any Property constituting Collateral, 100% with respect to such Collateral) of the consideration paid in connection therewith shall be in cash or, in the case of a sale or other Disposition not involving any Property constituting Collateral, Cash Equivalents, such payment to be contemporaneous with consummation of such transaction, and shall be in an amount not less than the fair market value of the Property disposed of;

(iii)    all sales or other Dispositions of Collateral between or among two or more Obligors shall be made expressly subject to the continuation of Agent's Lien on the Property being sold or otherwise Disposed of;

(iv)    no later than five Business Days prior to any such sale or other Disposition, Borrower Agent shall have delivered to Agent a certificate of a Senior Officer of Borrower Agent or its general partner specifying the anticipated date of such sale or other Disposition, briefly describing the assets to be sold or otherwise disposed of and setting forth the fair market value of such assets and the aggregate consideration and the Net Cash Proceeds to be received for such assets in connection with such Disposition;

(v)    Obligors shall remit all Net Cash Proceeds of any sale or other Disposition of Collateral to Agent for deposit into the Springing Dominion Account (if no Cash Dominion Trigger Event then exists) or into a Dominion Account (if a Cash Dominion Trigger Event then exists) of the applicable Obligors, and

(vi)    Obligors shall apply all Net Cash Proceeds of any sale or other Disposition of Property not constituting Collateral, within 360 days after the receipt thereof and at the option of Borrower Agent, to make Investments consisting of an Acquisition permitted by Section 9.2.2, to make Capital Expenditures permitted by this Agreement, to acquire other

long-term Property used or useful in a business not prohibited by this Agreement, or to repay Loans; and

(vii)    no Default or Event of Default exists at the time thereof or will arise as a result thereof; and

provided, further, however, that any sales or Dispositions (including sales or Dispositions of Collateral) pursuant to Section 9.2.5(d) shall not be required to comply with the requirements referred to in clause (ii) preceding.

Notwithstanding the foregoing, a Borrower may make one or more Dispositions of its Accounts from time to time if (but only if) each of the following requirements is satisfied with respect to such Disposition, in which case such Disposition shall constitute a "Permitted Accounts Transaction":

(A)    such Disposition shall be a "true sale" of the Accounts of such Borrower and pursuant to an arms-length transaction with a Person other than an Affiliate of such Borrower;

(B)    Borrower Agent shall notify Agent in writing, at least ten Business Days prior to such Borrower's execution and delivery of any agreement relating to such Disposition of Accounts, of the terms of such proposed Disposition in reasonable detail, which terms shall consist of (i) the identity of the Borrower that proposes to make such Disposition, (ii) the identity of the Account Debtor whose Accounts are proposed to be the subject of such Disposition, and (iii) the identity of the proposed purchaser of such Accounts, and Borrower Agent shall also provide to Agent any other information in reasonable detail as Agent may promptly, reasonably and subsequently (within five Business Days of Agent's receipt of such terms) request relating thereto;

(C)    if required by Agent, such Borrower, the purchaser of such Accounts and Agent shall have entered into an intercreditor agreement in form and substance reasonably satisfactory to Agent (which intercreditor agreement may, among other reasonable terms and provisions, provide that Agent and such purchaser shall turn over any proceeds of Accounts which rightfully belong to the other Person and provide that Agent's security interest in such Accounts to be sold shall be released automatically effective upon the consummation of the sale of such Accounts as permitted by clause (c) of Section 11.2.1);

(D)    at least two Business Days prior to the first such Disposition of Accounts of such Account Debtor, Borrower Agent shall have delivered to Agent a proforma of the then current Borrowing Base Certificate which shall exclude all Accounts of the Account Debtor whose Accounts are proposed to be sold pursuant to such Disposition (whether or not the Accounts of such Account Debtor are or may be sold pursuant to such Disposition or otherwise) from Eligible Accounts and, in the event that the Borrowing Base as so calculated pursuant thereto reflects that an Overadvance would exist after giving effect to the exclusion of all such Accounts from Eligible Accounts, Borrowers shall, prior to or concurrently with the consummation of such initial Disposition of Accounts, prepay the Revolver Loans and/or otherwise do what is necessary to eliminate such Overadvance; and

(E)    no Default or Event of Default will exist at the time of any such Disposition of Accounts or will arise as a result thereof.
