Production Royalty

Net Smelter Returns

Calculation and Payment of Production Royalty

With respect to each sale or other disposition of Products by the Company, the Production Royalty will become due and payable within 30 days of the end of the calendar quarter during which the Company receives payment for Products sold.

All Production Royalty payments will be considered final and in full satisfaction of all obligations of the Company with respect thereto, unless the Royalty Holder gives the Company written notice describing and setting forth a specific objection to the determination thereof within 30 days after receipt by the Royalty Holder of a “Royalty Statement” representing calculation of the Production Royalty payment and including copies of all third party sales invoices for Products during the respective calendar quarter. If the Royalty Holder objects to a particular Royalty Statement as herein provided, the Royalty Holder shall, for a period of 45 days after the Company’s receipt of notice of such objection, have the right, upon reasonable notice and at reasonable time, to have the Company’s accounts and records relating to the calculation of the Production Royalty in question audited by a certified professional accountant acceptable to the Royalty Holder and to the Company. If such audit determines that there has been a deficiency or an excess in the payment made to the Royalty Holder such deficiency or excess will be resolved by adjusting the next Production Royalty payment or credit due hereunder. The Royalty Holder will pay all costs of such audit unless a deficiency of 2% or more of the amount determined by the Company to be due to the Royalty Holder is determined to exist. The Company will pay the costs of such audit if a deficiency of 2% or more of the amount due is determined to exist. All books and records used by the Company to calculate the Production Royalty due hereunder will be kept in accordance with generally accepted accounting principles consistently applied. Failure on the part of the Royalty Holder to make claim on the Company for adjustment to its Production Royalty payment in such 45-day period will establish the correctness and preclude the filing of exceptions thereto or making of claims for adjustment thereon, provided that nothing herein will limit the time in which the Royalty Holder may commence a proceeding for fraud, concealment or misrepresentation. The foregoing notwithstanding, the parties further agree that any objection related to the payment of the Third Party Royalty (as defined in the Option Agreement) that may be raised by such third party shall be presented at such time and in such manner as specified in the royalty agreement between the third party and the Royalty Holder.
