Article II. Royalty Payment

A. Royalty. During the term of this Agreement, HiCrush agrees to pay Alcorn HC a royalty (the “Royalty”) equal to the sum of (i) $*** for each ton of Frac Sand extracted from the Acquired Property or Property Block and processed, sold and delivered by HiCrush, including its affiliates, successors and assigns, for which HiCrush has received payment in full and (ii) $*** for each ton of Raw Sand extracted from the Acquired Property or the Property Block and sold and delivered by HiCrush, including its affiliates, successors and assigns, for which HiCrush has received payment in full. The Royalty paid to Alcorn HC hereunder shall not be reduced for any taxes, expenses and other burdens.

Notwithstanding anything to the contrary contained in this Agreement, no Royalty shall be paid on Frac Sand by HiCrush’s successors or assigns where such Frac Sand is extracted from land in the Property Block that was owned or leased by such successor or assign of HiCrush prior to the date that such successor or assign became bound by the terms of this Agreement.

B. Arms Length Transaction. If Frac Sand or Raw Sand is (i) extracted from the Acquired Property or the Property Block and processed by HiCrush, including its affiliates, successors and assigns, and (ii) used by HiCrush, including its affiliates, successors and assigns without any payment for such Frac Sand or Raw Sand, then it shall be presumed for purposes of this Agreement that such entity purchased the amount of Frac Sand or Raw Sand used by such entity for which no payment was made and a Royalty equal to the sum of $*** for each ton of Frac Sand or Raw Sand used by such entity shall be paid to Alcorn HC pursuant to the terms of this Agreement.

C. Time of Payment and Payment Disputes. The Royalty payable under this Agreement with respect to a particular fiscal quarter shall be due and payable, without interest thereon, within 30 days after the end of such quarter (the “Due Date”). Each Royalty payment shall be accompanied by an unaudited royalty report showing the tonnages extracted from the Acquired Property and Property Block and sold by HiCrush to which that Royalty payment pertains. HiCrush will furnish to Alcorn HC its annual audited accounting records relating to the Royalty (the “Royalty Records”), prepared by a nationally recognized public accounting firm, promptly after HiCrush has received such records, which shall in no event be later than April 30 of each calendar year. If there is any difference between (i) the aggregate amount of the Royalty that was paid to Alcorn HC during the prior year and (ii) the aggregate amount of the Royalty that should have been paid to Alcorn HC during the prior year as calculated in accordance with the Royalty Records, such difference will be reconciled on the next Due Date.

D. Termination of Agreement. If Alcorn HC, or any affiliate of Alcorn HC at the time of such affiliation or within three years of such affiliation, purchases or leases (i) any property located in the Property Block or (ii) any portion of any property that is contiguous to any property located in the Property Block or the Acquired Property, then HiCrush shall no longer be obligated to pay any Royalty to Alcorn HC pursuant to Section II.A of this Agreement and this Agreement shall automatically be terminated and of no further force and effect.

E. Annual State Certification. Upon request by Alcorn HC, HiCrush shall provide evidence to Alcorn HC that HiCrush is in compliance with the applicable annual state certification of any weight scales that are used to weigh Frac Sand for which a Royalty shall be paid under Section II.A of this Agreement.

F. Interest. Any Royalty payment that is not made within *** of the Due Date shall accrue interest at the rate of *** per month, or the maximum rate allowed by Wisconsin law, beginning on the date such payment becomes past due, and continuing thereafter until paid in full.

Article III. Miscellaneous

A. Representations and Warranties. Each Party hereby represents and warrants that it has due authority to enter into this Agreement and that this Agreement and the terms and provisions provided for herein do not and will not violate any agreements by which such Party may be bound.

B. No Rights in Plant Operation or Business. This Agreement provides Alcorn HC only the right to payment of monies as expressly provided for herein.

C. Assignment. Each Party may assign this Agreement to any other individual or entity with prior written notice to the other Party; provided, however, that Alcorn HC may not assign any of its rights, duties and obligations under this Agreement to any entity or person that is directly or indirectly in competition with HiCrush or any of HiCrush’s affiliates without the prior written consent of HiCrush.
