“Subject to Section 2.1(d)Section 2.2(h) and Section 2.3, (i) each Common Unit (including all Canceled Awards) issued and outstanding as of immediately prior to the Effective Time will be converted into the right to receive 1.09 (the “Common Unit Equity Consideration” and such ratio the “Exchange Ratio”) Parent Units and cash in an amount of $6.20 per Common Unit (including all Canceled Awards) (the “Cash Consideration”, and together with the Common Unit Equity Consideration, the “Common Merger Consideration”), (ii) each Class A Unit issued and outstanding as




of immediately prior to the Effective Time will be converted into the right to receive (x) 1.09 Parent Class A Units plus (y) the number of Parent Class A Units equal to a fraction, the numerator of which is the Fully Diluted Cash Consideration and the denominator of which is the closing trading price of Parent Units on the trading day immediately preceding the Closing Date (the “Class A Consideration” and such ratio the “Class A Exchange Ratio”)  and (iii) each Class B Unit issued and outstanding as of immediately prior to the Effective Time will be converted into the right to receive 1 Parent Class B Unit (the “Class B Consideration” and such ratio, the “Class B Exchange Ratio”).  As used in this Agreement, “Fully Diluted Cash Consideration” means a fraction, the numerator of which is the aggregate dollar amount obtained by multiplying the Cash Consideration by the sum of (x) the number of Common Units (including all Canceled Awards) plus (y) the number of Class B Units, in each case outstanding immediately prior to the Effective Time, and the denominator of which is the number of Common Units (including all Canceled Awards) plus the number of Class A Units plus the number of Class B Units, in each case outstanding immediately prior to the Effective Time.”
