Section 1 — Registrant’s Business and Operations

Item 1.01. Entry into a Material Definitive Agreement

Credit Agreement Amendment

On December 6, 2013, Federal-Mogul Corporation (the “Company”) entered into an amendment (the “Amendment”) of its Term Loan and Revolving Credit Agreement, dated as of December 27, 2007 (as amended, the “Credit Agreement”), among the Company, the lenders party thereto, Citicorp USA, Inc., as Administrative Agent, JPMorgan Chase Bank, N.A., as Syndication Agent, and Wachovia Capital Finance Corporation and Wells Fargo Foothill, LLC, as Co-Documentation Agents, to amend its existing revolving credit facility to provide for a replacement revolving credit facility (the “Replacement Revolving Facility”). The Amendment, among other things, (i) increases the aggregate commitments available under the Replacement Revolving Facility from $540 million to $550 million, (ii) extends the maturity date of the Replacement Revolving Facility to December 6, 2018, subject to certain limited exceptions described below, and (iii) amends the Company’s borrowing base to provide the Company with additional liquidity. The Amendment does not amend the Company’s existing Tranche B or Tranche C term loans under the Credit Agreement.

Advances under the Replacement Revolving Facility generally bear interest at a variable rate per annum equal to (i) the Alternate Base Rate (ABL) (as defined in the Credit Agreement) plus an adjustable margin of 0.50% to 1.00% based on the average monthly availability under the Replacement Revolving Facility or (ii) Adjusted LIBOR Rate (ABL) (as defined in the Credit Agreement) plus a margin of 1.50% to 2.00% based on the average monthly availability under the Replacement Revolving Facility. An unused commitment fee of 0.375% also is payable under the terms of the Amendment.

Under certain limited circumstances the maturity date of the Replacement Revolving Facility may be accelerated. In the event that as of a particular determination date more than $300 million aggregate principal amount of the Company’s existing term loans and certain related refinancing indebtedness will become due within 91 days of such determination date, the Replacement Revolving Facility will mature on such determination date.

The descriptions of the Amendment and the Replacement Revolving Facility set forth above are qualified in their entirety by reference to the Amendment filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated by reference herein.

Backstop Commitment on Term Loan

On December 6, 2013, High River Limited Partnership, an affiliate of Carl C. Icahn and the Company’s largest stockholder (“High River”), entered into a backstop commitment letter (the “Backstop Commitment”) in favor of the Company with respect to its existing Tranche B term loan that matures in December 2014. The Backstop Commitment provides that if the Company is unable to refinance its Tranche B term loan on or prior to September 27, 2014, High River Limited Partnership or an affiliate thereof with at least the same net worth (the “Provider”) will provide loan financing of up to $1.6 billion to the Company and its subsidiaries on arms-length terms to provide the funding necessary to repay the Tranche B term loan. The High River loan will be subject to negotiation and execution of definitive documentation to be approved by the independent directors of the Company.

The description of the Backstop Commitment set forth above is qualified in its entirety by reference to the Backstop Commitment filed as Exhibit 10.2 to this Current Report on Form 8-K and incorporated by reference herein.
