(“Royal”) and Secured Promissory Note, dated September 30, 2016 originally payable by Royal to Weston Energy LLC, as assigned to Rhino (the “Weston Note”)

Dear Bill:

As you are aware, Rhino and Royal are parties to the Rhino Note and, by assignment, the Weston Note.

Under the terms of the Rhino Note, Royal has made total payments of $5,000,000. The total amount currently outstanding under the Rhino Note is $2,000,000. Under the terms of the Weston Note, the total amount outstanding is $2,000,000. Total aggregate amounts due under the Rhino Note and the Weston Note are referred to herein as the “Outstanding Balance”.

It is the intent of Rhino and Royal to amend the terms of the Rhino Note and the Weston Note to extend the maturity dates thereof, and Rhino and Royal hereby agree that the maturity dates under the Rhino Note and the Weston Note are hereby extended to December 31, 2018, at which time the Outstanding Balance shall be due and payable to Rhino in full. Rhino and Royal further agree that the Outstanding Balance, including any interest thereon, may be converted, at the option of Royal, at any time prior to December 31, 2018, in exchange for unregistered Royal common stock issued to Rhino at a price per share equal to seventy five percent (75%) of the volume weighted average closing price for the ninety (90) trading days preceding the date of conversion, if such shall occur, provided that for the purpose of this calculation, such average closing price shall be no less than $3.50 and no more than $7.50.
