Notwithstanding the previous sentence, any deficiency owed by HFRM due to its failure to satisfy any Minimum Revenue Commitment, if any, set forth on Exhibit C, as to any Applicable Asset for a Contract Quarter shall be offset by any revenue owed to HEP Operating in excess of any Minimum Revenue Commitment for such Contract Quarter set forth on Exhibit C from any other Applicable Asset at the same location. The Deficiency Notice shall (i) specify in reasonable detail the nature of any deficiency and (ii) specify the approximate dollar amount that HEP Operating believes would have been paid by HFRM to HEP Operating if HFRM had complied with its Minimum Revenue Commitment obligations pursuant to this Agreement (the “Deficiency Payment”). HFRM shall pay its Deficiency Payment to HEP Operating upon the later of: (A) ten (10) days after its receipt of the Deficiency Notice and (B) thirty (30) days following the end of the related Contract Quarter.

10.2    Disputed Deficiency Notices. If HFRM disagrees with the Deficiency Notice, then, following the payment of the undisputed portion of the Deficiency Payment to HEP Operating, if any, HFRM shall send written notice thereof regarding the disputed portion of the Deficiency Payment to

HEP Operating. Thereafter, a senior officer of HF Sinclair (on behalf of HFRM) and a senior officer of the Partnership (on behalf of HEP Operating) shall meet or communicate by telephone at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary and shall negotiate in good faith to attempt to resolve any differences that they may have with respect to matters specified in the Deficiency Notice. During the 30-day period following the payment of the Deficiency Payment, HFRM shall have access to the working papers of HEP Operating relating to its Deficiency Notice. If such differences are not resolved within thirty (30) days following HFRM’s receipt of its Deficiency Notice, HFRM and HEP Operating shall, within forty-five (45) days following HFRM’s receipt of the Deficiency Notice, submit any and all matters which remain in dispute and which were properly included in the Deficiency Notice to dispute resolution in accordance with the Omnibus Agreement.

10.3    Payment of Amounts No Longer Disputed. If it is finally determined pursuant to this Article 10 that HFRM is required to pay any or all of the disputed portion of the Deficiency Payment, HFRM shall promptly pay such amount to HEP Operating, together with interest thereon at the Prime Rate, in immediately available funds.

10.4    Contract Quarters Independent. The fact that HFRM has exceeded or fallen short of the Minimum Revenue Commitment with respect to any Contract Quarter shall not be considered in determining whether HFRM meets, exceeds or falls short of the Minimum Revenue Commitment with respect to any other Contract Quarter, and the amount of any such excess or shortfall shall not be counted towards or against the Minimum Revenue Commitment with respect to any other Contract Quarter.”
