Item 1.01 — Entry into a Material Definitive Agreement.

On October 15, 2013, Huntsman International LLC (“HI”), a wholly-owned subsidiary of Huntsman Corporation (“HC”), entered into the Tenth Amendment to Credit Agreement, Second Amendment to Collateral Security Agreement, Second Amendment to Pledge Agreement and Second Amendment to Subsidiary Guaranty (the “Amendment”) with JPMorgan Chase Bank, N.A., as administrative agent.

The Amendment modified the Credit Agreement dated as of August 16, 2005 among HI, the lenders from time to time party thereto and JPMorgan Chase Bank, N.A., as administrative agent (as amended, the “Credit Agreement”) to permit, among other things, (x)  a new senior secured term loan facility in an aggregate principal amount of up to $1,200 million under the Credit Agreement (the “New Term Loans”), (y)  a senior secured revolving commitment increase in an aggregate principal amount of up to $200 million under the Credit Agreement (the “Revolving Increase”) and (z) future incremental term facilities under the Credit Agreement in an amount up to $950 million and future incremental revolving facilities under the Credit Agreement in an amount up to $200 million (the “Incremental Facilities”).

To the extent funded, the proceeds of the New Term Loans will be used to pay the consideration in connection with the acquisition by HI of the Performance Additives and Titanium Dioxide business of Rockwood Specialties Group, Inc. (the “Acquisition”) or, if the Acquisition is not consummated, to refinance certain indebtedness of HI (the “Refinancing”).  To the extent funded, the proceeds of loans under the revolving facility including the Revolving Increase may be used for working capital and other general corporate purposes and to pay transaction costs.  To the extent they become effective, (i) the New Term Loans will be funded at the time of the Acquisition or the Refinancing, as applicable, and (ii) the Revolving Increase will become effective at the time of the Acquisition, in each case subject to the satisfaction of certain conditions precedent.  The proceeds of loans under the Incremental Facilities may be used for general corporate purposes.

To the extent funded, the New Term Loans will mature on the seventh anniversary of the date such New Term Loans are funded and will amortize in aggregate annual amounts equal to 1% of the original principal amount of the New Term Loans, payable quarterly commencing with the first full fiscal quarter ended after the date such New Term Loans are funded.  To the extent funded, the loans pursuant to the Revolving Increase will mature on the same date as the existing revolving loans under the Credit Agreement.

The foregoing does not constitute a complete summary of the terms of the Amendment.  The description of the terms of the Amendment is qualified in its entirety by reference to such agreement, attached hereto as Exhibit 10.1 and incorporated herein by reference.
