Upon receipt of an Exercise Notice, Holly UNEV will be obligated to deliver the Holly UNEV Interests in accordance with Section 1.3 of this Agreement, HEP-Operating will be obligated to deliver the Option Purchase Price on the Closing Date (or if the Closing Date falls on a day that is not a business day, the business day immediately prior to the Closing Date) and HEP-Operating or Holly UNEV will be obligated to deliver the Closing Adjustment Amount in accordance with Section 1.6 if such amount is positive or negative, respectively.

     (b) If within 45 days following delivery of the Final Closing Financial Statements to Holly UNEV, Holly UNEV has not delivered to HEP-Operating written notice (the “Objection Notice”) of its objections to the Closing Operations Amount certified by HEP–Operating (such Objection Notice must contain a statement describing in reasonable detail the basis of such objections and the amounts so disputed), then the Closing Operations Amount as calculated from such Final Closing Financial Statements shall be deemed final and conclusive and shall be “Final Operations Amount,” and each of the parties hereto agrees that such amounts shall thereafter not be subject to any appeal or further challenge hereunder or otherwise. If Holly UNEV delivers the Objection Notice within such 45-day period, then HEP-Operating and Holly UNEV shall submit the objections set forth in the Objection Notice to binding arbitration in accordance with Section 8.11 and “Final Operations Amount” will be determined pursuant to binding arbitration.

     1.6 Adjustment Payment. If the Final Operations Amount as determined pursuant to Section 1.5 would result in a (i) positive Closing Adjustment Amount, then HEP-Operating will promptly pay an amount in cash to Holly UNEV, in immediately available funds, equal to such

excess, or (ii) negative Closing Adjustment Amount, then Holly UNEV shall promptly pay an amount in cash to HEP-Operating, in immediately available funds, equal to such shortfall.
