Canadian International Oil Corp. (CIOC) - Sale of a loan interest

Guernsey (21 December 2016) - Riverstone Energy Limited ("REL" or the "Company"), announces that it has sold its entire CAN$ 28 million second lien loan (approximately US$ 21 million) interest in CIOC (the "CIOC Loan Interest") to an affiliate of Kendall Family Investments, LLC ("KFI"). The consideration payable by the KFI affiliate reflects the par value of the loan.

The CIOC Loan Interest, which has a maturity in 2020 and confers no equity rights in respect of CIOC, was provided to CIOC by the Company in December 2015. The proceeds from the sale of the CIOC Loan Interest will be used towards the exercise of its Warrants in CIOC, which the Company believes represents a more attractive return than the loan.  KFI is a substantial shareholder of the Company under Chapter 11 of the Listing Rules. As such, the sale of the CIOC Loan Interest to its affiliate amounts to a smaller related party transaction as defined in Listing Rule 11.1.10.
