Exchange for Class A Units in lieu of Conversion. Notwithstanding any provision to the contrary herein, LTIP Units owned by each of the Partners listed in (i) Schedule II under the heading “U.K.” and (ii) Schedule III (“U.K. LTIP Units”) are subject to exchange as set out in this Section 1.15 rather than conversion. Except as otherwise agreed between the General Partner and the applicable LTIP Unit Limited Partner, subject to the expiration of any applicable LTIP Unit Restricted Period (as defined above), on the first date that a Participating LTIP Unit (including, for purposes of clarity, a Founder LTIP Unit) that is a U.K. LTIP Unit has attained a Book-Up Target of zero, the holder of such Participating LTIP Unit shall have the right, at such holder’s option (but subject to the procedures described below), to exchange such Participating LTIP Unit for, at the election of the General Partner in its sole discretion: (A) a number (or fraction thereof) of fully paid and non-assessable Class A Units equal to the LTIP Conversion Factor (as defined above); or (B)(i) an amount of cash equal to the value of the Class A Units such holder would be entitled to receive pursuant to clause (A) (including, for the avoidance of doubt, the value attributable to such holder’s future right to become party to the Tax Receivable Agreement). In order to exercise such right of exchange, a holder of LTIP Units shall deliver a notice in the form reasonably acceptable to the Partnership no less than 60 days prior to the date specified in such notice as the date of exchange, which date shall be the first day of a calendar quarter. For the avoidance of doubt, none of the U.K. LTIP Units shall be convertible into Class A Units (or any other securities) under any circumstances, and the intent of this Section 1.15 is that (1) rather than converting into Class A Units (whether automatically, pursuant to an LTIP Unit Forced Conversion or otherwise), U.K. LTIP Units shall be exchanged for the consideration set forth above and (2) all provisions of this Agreement relating to converting LTIP Units shall apply to the U.K. LTIP Units but giving effect to the terms of this Section 1.15, with references to “conversion,” “convert into” or similar language replaced with “exchange,” “exchange for” or similar language.
