Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

On July 30, 2013, Penske Corporation and its wholly owned subsidiary, Penske Automotive Holdings Corp (together with Penske Corporation, “Penske”) entered into a Stockholders Agreement (the “Stockholders Agreement”) with Mitsui.  The Stockholders Agreement terminates and supersedes the prior Stockholders Agreement, dated as of March 26, 2004, by and among International Motor Cars Group I, L.L.C., International Motor Cars Group II, L.L.C., Penske and Mitsui (the “Prior Stockholders Agreement”).  The Stockholders Agreement is filed with this Amendment No. 26 as Exhibit 46 and is incorporated herein by reference.

The Stockholders Agreement has a term expiring on March 26, 2024 (i.e., the 10th anniversary of the expiration date of the Prior Stockholders Agreement).  Among other things, the Stockholders Agreement requires that Mitsui vote all of the shares of Common Stock they beneficially own in favor of up to 14 persons voted for by Penske for election as directors of the Company.  The Stockholders Agreement also requires that Penske vote all of the shares of Common Stock beneficially owned by Penske in favor of (i) one representative of Mitsui for election as a director of the Company as long as Mitsui beneficially owns 10% or more (but less than 20%) of the Common Stock, and (ii) two representatives of Mitsui for election as directors of the Company as long as Mitsui beneficially owns 20% or more of the Common Stock.  In addition, in the event Penske desires to transfer equity securities in the Company to a third party during the term of the Stockholders Agreement (other than one or more transfers not exceeding 1,992,408 shares in the aggregate), Penske must permit Mitsui to participate in such transfer on a pro rata basis.
