For Riverstone Energy Limited:

Note:

The Investment Manager is charged with proposing the valuation of the assets held by REL through the Partnership. The Partnership has directed that securities and instruments be valued at their fair value. REL's valuation policy follows IFRS and IPEV Valuation Guidelines. The Investment Manager values each underlying investment in accordance with the Riverstone valuation policy, the IFRS accounting standards and IPEV Valuation Guidelines. The Investment Manager has applied Riverstone's valuation policy consistently quarter to quarter since inception. The value of REL's portion of that investment is derived by multiplying its ownership percentage by the value of the underlying investment. If there is any divergence between the Riverstone valuation policy and REL's valuation policy, the Partnership's proportion of the total holding will follow REL's valuation policy. There were no valuation adjustments recorded by REL as a result of differences in IFRS and U.S. Generally Accepted Accounting Policies for the period ended 30 September 2016 or in any period to date. Valuations of REL's investments through the Partnership are determined by the Investment Manager and disclosed quarterly to investors, subject to Board approval.

Riverstone values its investments using common industry valuation techniques, including comparable public market valuation, comparable merger and acquisition transaction valuation, and discounted cash flow valuation.

For development-type investments, Riverstone also considers the recognition of appreciation or depreciation of subsequent financing rounds, if any. For those early stage privately held companies where there are other indicators of a decline in the value of the investment, Riverstone will value the investment accordingly even in the absence of a subsequent financing round.

Riverstone reviews the valuations on a quarterly basis with the assistance of the Riverstone valuation committee as part of the valuation process.

The Audit Committee reviews the valuations of the Company's investments held through the Partnership, and makes a recommendation to the Board for formal consideration and acceptance.
