On December 23, 2013 (the “Effective Date”), Chrysler Group LLC (the “Company”), entered into an Assignment and Amendment (the “Amendment”), among the Company, the lenders party thereto, and Citibank, N.A., as administrative agent (the “Administrative Agent”), under the Amended and Restated Credit Agreement, dated as of June 21, 2013 (the “Credit Agreement”), among the Company, the lenders party thereto from time to time, the Administrative Agent and Citibank, N.A., as collateral agent. The Credit Agreement provides for senior secured credit facilities consisting of a Tranche B term loan with an original principal balance of $3.0 billion (the “Tranche B Term Loan”) and a revolving credit facility of $1.3 billion.

The Amendment amended the Credit Agreement by reducing the applicable interest rate spreads on the Tranche B Term Loan by 0.50% per annum and reducing the rate floors applicable to the Tranche B Term Loan by 0.25% per annum. As a result, the outstanding principal balance of the Tranche B Term Loan will bear interest, at the Company’s option, either at a base rate plus 1.75% per annum or at the reserve-adjusted Eurodollar rate plus 2.75% per annum, subject to a base rate floor of 1.75% per annum or a reserve-adjusted Eurodollar rate floor of 0.75% per annum. As of the Effective Date, the outstanding principal balance of the Tranche B Term Loan was approximately $2.9 billion.

If the Company voluntarily prepays or reprices all or any portion of the Tranche B Term Loan before the six-month anniversary of the Effective Date, the Company will be obligated to pay a call premium equal to 1.0% of the principal amount prepaid or repriced.

All other terms of the Tranche B Term Loan, including maturity date, remain unchanged.

The foregoing description of the Amendment is qualified in its entirety by reference to the complete terms and conditions of the Amendment, a copy of which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.

The information provided in Item 1.01 is incorporated herein by reference.
