Eleven.Two. In considerat ion o f the fact that the Lease Agreement prov ides for the lease of min ing r ights , the Part ies hereby estab l ish in the fo l lowing sect ions the product ion and sa les quotas to which the Company sha l l be bound under the lease of the OMA Rights.

The Part ies acknowledge that the Base

Signature Version 45 Quota is estab l ished for the ent i re term of the Agreement and does not impose on the Company an ob l igat ion to p roduce or se l l a speci f ic quant i ty annual ly ; therefore, the Base Quota is not reduced or ext ingu ished due to a lack o f annual product ion or sa les in a g iven year, wi thout pre jud ice to the ob l igat ion to pay the Guaranteed Min imum Rent estab l ished in C ▇▇▇▇▇ Eight (Commitment to Operat ion and Guaranteed Min imum Rent) o f the Lease Agreement .
