September 14, 2017 (the &ldquo;<U>Effective Date</U>&rdquo;), by and between Glencore AG and Givolon (the &ldquo;<U>Framework Agreement</U>&rdquo;),
among other things, on and as of the Effective Date, (i) Glencore AG transferred 27,500,000 shares of Common Stock, representing
approximately 31.5% of the issued and outstanding shares of Common Stock (the &ldquo;<U>Specified Shares</U>&rdquo;) to Givolon
(a wholly-owned subsidiary of Glencore AG at such time) for aggregate purchase price of $495,845,625 (the &ldquo;<U>SPA Purchase
Price</U>&rdquo;), and (ii) Glencore AG and Givolon entered into the stock-settled Century TRS (as further described and defined
in Item 6 below) and Glencore AG acquired from Givolon the American-style Century Call Option (as further described and defined
in Item 6 below) which give Glencore AG the right to acquire from Givolon a number of shares of Common Stock equivalent to the
Specified Shares, for aggregate consideration (the &ldquo;<U>Settlement Price</U>&rdquo;) equal to, in either case, the SPA Purchase
Price, which (x) in the case of the Century TRS, is the final settlement amount payable by Glencore AG to Givolon, and (y) in the
case of the Century Call Option, is the combined amount of the premium (which is equal to 85% of the SPA Purchase Price) and the
exercise price (which is equal to 15% of the SPA Purchase Price) payable by Glencore AG to Givolon. Eighty-five percent of the
SPA Purchase Price and the Century Call Option premium were paid on the Effective Date by set-off of against each other, and the
remaining 15% of the SPA Purchase Price will be paid by set-off against the Century Call Option exercise price or 15% of the final
settlement amount payable under the Century TRS, as applicable. Subsequently, on the Effective Date, Ryfold entered into a Joinder
Agreement in favor of Glencore AG and Givolon by which Ryfold became a party to the Framework Agreement (the &ldquo;<U>Joinder
Agreement</U>&rdquo;) and pursuant to which (A) Glencore AG transferred 100% of Givolon&rsquo;s equity interests (the &ldquo;<U>Givolon
Shares</U>&rdquo;) to Ryfold for aggregate consideration of $100, and (B) Glencore AG acquired from Ryfold the American-style Givolon
Call Option (as further described and defined in Item 6 below) which gives Glencore AG the right to acquire the Givolon Shares
from Ryfold. The transactions provided for under the Framework Agreement and the other agreements that form a part thereof (together
with the Framework Agreement, the &ldquo;<U>Transaction Agreements</U>&rdquo;) are collectively referred to as the &ldquo;<U>Givolon

in which Givolon would pledge the Specified Shares as collateral to secure a credit facility (the &ldquo;<U>Givolon Credit Facility</U>&rdquo;)
from one or more lenders (the &ldquo;<U>Givolon Lenders</U>&rdquo;), the proceeds of which Givolon would use to make loans to Glencore
AG (the &ldquo;<U>Givolon Stock Pledge</U>&rdquo;). Glencore AG and Givolon are in the process of negotiating the Proposed Financing
with a potential lender. The Framework Agreement contemplates that Glencore AG and its affiliates may from time to time transfer
additional assets to Givolon, Ryfold and other subsidiaries of Ryfold, to be pledged to secure the Givolon Credit Facility or other
credit facilities, and the proceeds of which would be used by Givolon, Ryfold or such other subsidiaries of Ryfold to provide one
or more credit facilities to Glencore AG or Glencore AG&rsquo;s affiliates. Collectively, the transactions contemplated under the
Framework Agreement are intended to be treated as a loan of the Specified Shares under Section 1058 of the Internal Revenue Code
of 1986, as amended.</P>

to December 31, 2022, and will be finally settled by set-off against an equivalent amount of the settlement payment under the Century
TRS or the exercise price under Century Call Option, as applicable. Interest will accrue and be payable semi-annually in arrears

Stock equal to the Subject Shares (the &ldquo;<U>Century Call Option</U>&rdquo;). Under the terms of the Century TRS and the Century
Call Option, the Century TRS is scheduled to expire and settle after expiration of the Century Call Option, so that Glencore AG
will acquire the Subject Shares under the Century TRS if Glencore AG does not exercise the Century Call Option. In addition, as
described further below, the Century TRS will automatically terminate, with no remaining obligations on the part of either party,
upon settlement of the Century Call Option. As a result, under the Century TRS and the Century Call Option, Glencore AG has the
right to acquire and Givolon has the obligation to deliver to Glencore AG an aggregate number of shares equal to the Subject Shares.</P>

TRS, Glencore AG and Givolon would enter into an agreement, the terms of which are agreed to under the Framework Agreement, under
which (A) Givolon would deliver the Subject Shares to Glencore AG, and (B) Glencore AG would be obligated to pay to Givolon the
Century TRS reference price which is equal to the Per Share Price for each Subject Share, which would be finally settled (x) by
