(i) the right to participate in the policy-making functions of the Issuer, (ii) a preemptive right to acquire Common Units in connection with certain issuances and dispositions by the Issuer and (iii) a right to purchase all Common Units and other Issuer securities owned by EPC Partners, EPCO and their affiliates upon a change in control of the Issuer.
