Indenture

On December 8, 2015, Group 1 Automotive, Inc. (the “Company”) completed its private placement (the “Offering”) of $300,000,000 aggregate principal amount of its 5.250% Senior Notes due 2023 (the “Notes”) to Wells Fargo Securities, LLC and the other initial purchasers (the “Initial Purchasers”). The Notes are guaranteed on an unsecured senior basis (the “Guarantees”) by certain of the Company’s subsidiaries (collectively, the “Guarantors”). The terms of the Notes are governed by the indenture dated as of December 8, 2015 (the “Indenture”), by and among the Company, the Guarantors and Wells Fargo Bank, National Association, as trustee (the “Trustee”).

The Notes will mature on December 15, 2023, and interest is payable on the Notes on each June 15 and December 15, commencing on June 15, 2016. The Company may redeem up to 35% of the original principal amount of the Notes using the proceeds of certain equity offerings completed on or before December 15, 2018 at a redemption price of 105.250% of the principal amount of the Notes, together with accrued and unpaid interest, if any, to, but excluding, the date of redemption, provided that:

(i) at least 65% of the aggregate principal amount of all Notes issued remains outstanding after each such redemption; and

(ii) the redemption occurs within 120 days of the date of the closing of such equity offering.

Prior to December 15, 2018, the Company may redeem all or a part of the Notes at a redemption price equal to 100% of the principal amount of the Notes redeemed plus an applicable make-whole premium as of, and accrued and unpaid interest, if any, on the Notes redeemed to, the applicable date of redemption.

On or after December 15, 2018, the Company may on any one or more occasions redeem all or a part of the Notes at the following redemption prices (expressed as percentages of the principal amount) plus accrued and unpaid interest, if any, on the Notes redeemed, to, but excluding, the applicable redemption date, if redeemed during the 12-month period beginning on December 15 of the years indicated:

Upon the occurrence of a Change of Control (as defined in the Indenture), the Company will be required to make an offer to purchase all outstanding Notes at a purchase price equal to 101% of their principal amount plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

The Notes are the Company’s senior unsecured obligations and will rank: (i) equal in right of payment with all existing and future senior unsecured debt of the Company; (ii) effectively subordinated to all existing and future senior secured debt of the Company to the extent of the value of the assets securing such debt; (iii) senior in right of payment to all subordinated debt of the Company; and (iv) structurally subordinated to any debt of any non-guarantor subsidiaries.

The Indenture restricts the Company’s ability and the ability of its Restricted Subsidiaries (as defined in the Indenture) to: (i) incur additional debt and guarantee debt; (ii) pay dividends on its capital stock or repurchase its capital stock and make certain other restricted payments; (iii) enter into agreements limiting dividends and certain other restricted payments; (iv) prepay, redeem or repurchase subordinated debt; (v) grant liens on its assets; (vi) merge, consolidate or convey, transfer or lease all or substantially all of its assets; (vii) sell, transfer or otherwise dispose of property and assets; and (viii) engage in transactions with affiliates. These covenants are subject to a

number of important exceptions and qualifications. Certain covenants will be suspended and will not apply to the Notes for so long as the Notes have investment grade ratings from either Standard & Poor’s Ratings Services or Moody’s Investors Service, Inc. and no default or event of default shall have occurred and be continuing at the time of suspension.

The Indenture contains customary events of default, including:

A copy of the Indenture is filed as Exhibit 4.1 to this Form 8-K and is incorporated herein by reference. The description of the Indenture is a summary and is qualified in its entirety by the terms of the Indenture.
