Option

In connection with each closing (an “Offering Closing”) of the Class B Preferred Units Offering, the Partnership hereby grants to the Option Holders (as defined below) an option to purchase up to a number of Class C Preferred Units (as defined below) equal to 41.6777% of the number of Class B Preferred Units issued and sold at such Offering Closing.  Each such option relating to an Offering Closing shall be exercisable once (and not more than once) by providing written notice to the Partnership not more than 10 business days after the date of such Offering Closing.  If exercised, each such option shall be settled on a date to be agreed upon with the Partnership, which shall not be less than 10 business days nor more than 15 business days after the date of exercise.  The price to be paid per Class C Preferred Unit issued and sold pursuant to each such option shall be equal to the public offering price per Class B Preferred Unit in the Class B Preferred Units Offering.  As used herein (i) the term “Option Holders” means Highstar NGL Prism/IV-A Interco LLC, Highstar NGL Main Interco LLC, NGL CIV A, LLC and NGL Prism/IV-A Blocker LLC (the “Highstar Entities”) and each entity or account managed, advised

or sub-advised, directly or indirectly by the Highstar Entities and (ii) the term “Class C Preferred Units” means a new separate class of preferred limited partner interests in the Partnership constituting a separate class of equity interests with designations, preferences, rights and powers substantially similar to those of the Class B Preferred Units.  For purposes of each such option, the entities comprising the Option Holders shall act as a single entity, and each exercise of each such option shall be made pursuant to not more than one written notice provided by or on behalf of the Option Holders.

IN WITNESS WHEREOF, each of the undersigned have executed this instrument, effective as of the date first above written.
