MASTER TOLLING AGREEMENT

(Operating Assets)

This Master Tolling Agreement (this “Agreement”) is dated as of November 2, 2015, to be effective as of the Effective Time (as defined below) by and between the Persons set forth on Exhibit A (each hereinafter sometimes referred to as a “Party” and sometimes collectively referred to as the “Parties”).

RECITALS:

A. Pursuant to certain transactions identified on Exhibit B (the “Drop-Down Transactions”) HEP Operating acquired from each Applicable Refinery Owner the assets identified on Exhibit C (the “Applicable Assets”) which are located at each Refinery Complex.

B. In connection with each transaction between HEP Operating and the Applicable Refinery Owner, HEP Operating leased from the Applicable Refinery Owner land at the Applicable Refinery Owner’s Refinery Complex on which all or a part of the Applicable Assets are located.

C. The Parties desire to enter into a master agreement pursuant to which HEP Operating will provide certain services to the Applicable Refinery Owner with respect to the Applicable Assets from and after the Effective Time.

NOW, THEREFORE, in consideration of the covenants and obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereby agree as follows:

ARTICLE 1

DEFINITIONS AND INTERPRETATIONS

1.1 Definitions. Capitalized terms used throughout this Agreement and not otherwise defined herein shall have the meanings set forth on Exhibit D.

1.2 Interpretation. Matters relating to the interpretation of this Agreement are set forth on Exhibit E.

ARTICLE 2

AGREEMENT TO PURCHASE SERVICES

2.1 Intent. The Parties intend to be strictly bound by the terms set forth in this Agreement, which sets forth the Tolling Fees to be paid by the Applicable Refinery Owner to HEP Operating for providing certain processing services to the Applicable Refinery Owner.

2.2 Minimum Throughput Commitment. During the Applicable Term and subject to the terms and conditions of this Agreement, each Applicable Refinery Owner agrees as follows:

(a) Throughput Commitment. Subject to Article 2, the Applicable Refinery Owner commits to deliver to HEP Operating at the location of each Applicable Asset the Minimum Throughput Commitment of Feedstock for each Contract Quarter, and pay the Tolling Fees in exchange for HEP Operating providing the services necessary to process the Feedstock into the Products.

(b) Tolling Fees. The Applicable Refinery Owner shall pay the Tolling Fees for all quantities of Feedstock processed through the Applicable Asset in each Contract Quarter during the Applicable Term.

(c) Adjustment of Tolling Fees. The Tolling Fees shall be adjusted in the manner set forth on Exhibit C. To evidence the Parties’ agreement to each adjusted Tolling Fee, the Parties shall execute an amended, modified, revised or updated Exhibit C and attach it to this Agreement. Such amended, modified, revised or updated Exhibit C shall be sequentially numbered (e.g. Exhibit C-1, Exhibit C-2, etc.), dated and appended as an additional exhibit to this Agreement and shall replace the prior version of Exhibit C in its entirety, after its date of effectiveness.

(d) Reduction for Non-Force Majeure Events.

(1) If, as a result of HEP Operating’s operational difficulties or inability to provide sufficient capacity for the Minimum Throughput Commitment, HEP Operating fails to process and deliver to the Applicable Refinery Owner at least 95% of the volumes of Products expected to be derived from the volume of Feedstock processed with such Applicable Asset for a particular Contract Quarter based on the applicable Conversion Ratio, then the Tolling Fee applicable to that Contract Quarter will be reduced by a percentage equal to (A) 100% minus (B) the percentage represented by the ratio of (i) the volume of Products actually produced for the Contract Quarter to (ii) the volume of Products that would be produced from the volume of Feedstock delivered for the Contract Quarter based on the Conversion Ratio plus (C) 5%. If, as a result of a reduction to the Tolling Fee for a Contract Quarter under this Section 2.2(d)(1) the Applicable Refinery Owner shall have overpaid its Tolling Fees for the Contract Quarter, the Applicable Refinery Owner shall receive a credit against its Tolling Fees due for the following Contract Quarter in the amount of such overpayment.

(2) If the Aggregate Capacity of any Applicable Asset for any Contract Quarter is less than the Minimum Throughput Commitment for such Applicable Asset for such Contract Quarter, including any time period during which HEP Operating is performing a turnaround on the Applicable Asset, then the Minimum Throughput Commitment for such Applicable Asset for such Contract Quarter will be reduced by a percentage equal to (A) 100% minus (B) the percentage represented by the ratio of (i) the Aggregate Capacity for such Applicable Asset for such Contract Quarter to (ii) the Minimum Throughput Commitment for such Applicable Asset for such the Contract Quarter.

This Section 2.2(d) shall not apply in the event HEP Operating gives a Force Majeure Notice in accordance with the terms of Article IX of the Omnibus Agreement, in which case the Minimum Throughput Commitment shall be suspended to the extent contemplated in Article IX of the Omnibus Agreement and Article 3 of this Agreement.

(e) Pro-Rationing for Partial Periods. Notwithstanding the other provisions of this Section 2.1, in the event that the Effective Time is any date other than the first day of a Contract Quarter, then the Minimum Throughput Commitment for the initial partial Contract Quarter shall be prorated based upon the number of actual days between the date on which the Effective Time occurs and the end of such partial Contract Quarter. Similarly, notwithstanding the other provisions of this Section 2.1, if the end of the Applicable Term is on a day other than the last day of a Contract Quarter, then the Minimum Throughput Commitment shall be prorated based upon the number of actual days between the beginning of such partial Contract Quarter and the last day of the Applicable Term.

2.3 Measurement and Ownership of Delivered Volumes. Matters with respect to the measurement of delivered volumes of Feedstock and Products are set forth on Exhibit F. Applicable Refinery Owner shall at all times retain title to the Feedstock and the Products.

2.4 Obligations of HEP Operating. During the Applicable Term and subject to the terms and conditions of this Agreement, HEP Operating agrees to:

(a) own or lease, operate and maintain (directly or through a Subsidiary) the Applicable Assets and all related assets necessary to process the applicable Feedstock and produce and deliver the applicable Products to the Applicable Refinery Owner at the throughput levels required by this Agreement;

(b) provide the services required under this Agreement and perform all operations relating to the Applicable Assets; and

(c) maintain adequate property and liability insurance covering the Applicable Assets and any related assets owned by HEP Operating or its Affiliates and necessary for the operation of the Applicable Assets.

Notwithstanding the first sentence of this Section 2.4, subject to right of first refusal under Article V the Omnibus Agreement, HEP Operating or its Affiliate is free to sell any of its assets, including any Applicable Assets, and the Applicable Refinery Owner is free to merge with another entity and to sell all of its assets or equity to another entity at any time.

2.5 Notification of Utilization of Services. During the Applicable Term, the Applicable Refinery Owner will provide to HEP Operating written notification of the Applicable Refinery Owner’s reasonable good faith estimate of its anticipated future volumes of Feedstock to be delivered and the Applicable Refinery Owners’ requirements for Products as soon as reasonably practicable.

2.6 Scheduling and Accepting Movement. HEP Operating will use its reasonable commercial efforts to process, and schedule movement and accept movements of, Feedstocks in a manner that is consistent with the historical dealings between the Parties and their Affiliates, as such dealings may change from time to time.

2.7 Taxes. The Applicable Refinery Owner will pay all taxes, import duties, license fees and other charges by any Governmental Authority levied on or with respect to the Feedstocks processed and Products delivered to the Applicable Refinery Owner by HEP Operating. HEP Operating will pay all property and ad valorem taxes levied on, or with respect to, the Applicable Assets. Should either Party be required to pay or collect any taxes, duties, charges and or assessments pursuant to any Applicable Law or authority now in effect or hereafter to become effective which are payable by the any other Party pursuant to this Section 2.6, the Party subject to such tax shall promptly reimburse the Party collecting or paying the tax on its behalf for the amount of such tax.

2.8 Timing of Payments. The Applicable Refinery Owner will make payments to HEP Operating by electronic payment with immediately available funds on a monthly basis during the Applicable Term with respect to services rendered or reimbursable costs or expenses incurred by HEP Operating under this Agreement in the prior month. Payments not received by HEP Operating on or prior to the tenth day following the invoice date will accrue interest at the Prime Rate from the applicable payment due date until the date payment is made.

2.9 Increases in Tolling Fees. If new Applicable Laws are enacted that require HEP Operating to make capital expenditures with respect to the Applicable Assets, HEP Operating may amend the Tolling Fees in the manner set forth in Exhibit G in order to recover HEP Operating’s cost of complying with such new Applicable Laws (as determined by HEP Operating in good faith and assuming that such capital expenditures are financed at a reasonable rate and amortized on a mortgage style basis over a period equal to the then remaining Initial Term (or if such capital expenditures are incurred during any Expansion Term, the then remaining Expansion Term)). The Applicable Refinery Owner and HEP Operating shall use their reasonable commercial efforts to comply with such new Applicable Laws, and shall negotiate in good faith to mitigate the impact of such new Applicable Laws and to determine the amount of the new Tolling Fee rates. If the Applicable Refinery Owner and HEP Operating are unable to agree on the amount of the new Tolling Fee rates that HEP Operating will charge, such Tolling Fee rates will be resolved in the manner provided for in Article VIII of the Omnibus Agreement. Any other applicable exhibit to this Agreement will be updated, amended or revised, as applicable, in accordance with this Agreement to reflect any changes in Tolling Fee rates established in accordance with this Section 2.9.

2.10 No Guaranteed Minimum. Notwithstanding anything to the contrary set forth in this Agreement, there is no requirement that the Applicable Refinery Owner actually deliver any minimum quantity of Feedstock to the Applicable Assets, it being understood that the Applicable Refinery Owner’s obligation for failing to deliver sufficient quantities of Feedstock to satisfy the Minimum Throughput Commitment for any Contract Quarter is to make Deficiency Payments as provided in Article 6.

ARTICLE 3

FORCE MAJEURE

The rights and obligations of the Parties upon the occurrence of an event of Force Majeure will be determined in the manner set forth in Article IX of the Omnibus Agreement; provided that (a) any suspension of the obligations of the Parties under this Agreement as a result of an event of Force Majeure shall extend the Applicable Term (to the extent so affected) for a period equivalent to the duration of the inability set forth in the Force Majeure Notice, (b) the Applicable Refinery Owner will be required to pay any amounts accrued and due under this Agreement at the time of the Force Majeure event, and (c) if a Force Majeure event prevents either Party from performing substantially all of their respective obligations under this Agreement relating to a group of Applicable Assets for a period of more than twelve (12) consecutive months, this Agreement may be terminated as to such Applicable Assets (but not as to unaffected Applicable Assets) by either Party providing written notice thereof to the other Party.

ARTICLE 4

EFFECTIVENESS AND APPLICABLE TERM

This Agreement shall be effective as to each group of Applicable Assets as of the Effective Time and, unless terminated earlier in accordance with its terms, shall terminate with respect to each group of Applicable Assets upon the expiration of the initial term set forth on Exhibit C (the “Initial Term”); provided that, at the end of the Initial Term for each group of Applicable Assets, the Applicable Refinery Owner shall have the option to extend the Applicable Term for such group of Applicable Assets for an extension term beyond the Initial Term if, and to the extent, provided in Exhibit C (an “Extension Term”).

In the event an Extension Term is available for a group of Applicable Assets, the Applicable Refinery Owner shall give HEP Operating written notice of its exercise of its option to extend the Applicable Term with respect to such group of Applicable Assets at least 12 months prior to the end of the Initial Term for such group of Applicable Assets.

ARTICLE 5

NOTICES

Any notice or other communication given under this Agreement shall be in writing and shall be provided in the manner set forth in Article X of the Omnibus Agreement.

ARTICLE 6

DEFICIENCY PAYMENTS

6.1 Deficiency Notice; Deficiency Payments. As soon as practicable following the end of each Contract Quarter, HEP Operating shall deliver to the Applicable Refinery Owner a written notice (the “Deficiency Notice”) detailing any failure of the Applicable Refinery Owner to meet the Minimum Throughput Commitment for such Contract Quarter. The Deficiency Notice shall specify in reasonable detail the excess of (i) the dollar amount of the Tolling Fee that HEP Operating would have been paid by the Applicable Refinery Owner if the Applicable Refinery Owner had complied with its Minimum Throughput Commitment obligations for such Contract Quarter pursuant to this Agreement over (ii) the dollar amount of the Tolling Fee payable based on the Feedstock actually processed during such Contract Quarter (the “Deficiency Payment”). The Applicable Refinery Owner shall pay the Deficiency Payment to HEP Operating upon the later of: (A) ten (10) days after the Applicable Refinery Owner’s receipt of the Deficiency Notice and (B) thirty (30) days following the end of the related Contract Quarter, unless such day is not a Business Day, in which case the due date for payment shall be the next Business Day.

6.2 Disputed Deficiency Notices. If the Applicable Refinery Owner disagrees with all or any portion of the Deficiency Notice, then, prior to the due date of the Deficiency Payment, the Applicable Refinery Owner shall (i) send HEP Operating a written notice with an explanation of the basis for the dispute (a “Dispute Notice”) and (ii) pay HEP Operating the portion of the Deficiency Payment not disputed in such Dispute Notice. Thereafter, a senior officer of HollyFrontier (on behalf of the Applicable Refinery Owner) and a senior officer of the Partnership (on behalf of HEP Operating) shall meet in person 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 matters set forth in such Dispute Notice. During the 30-day period following the Applicable Refinery Owner’s timely delivery of such Dispute Notice, the Applicable Refinery Owner shall have reasonable access to the working papers of HEP Operating relating to the Deficiency Notice. If the matters set forth in such Dispute Notice are not resolved within thirty (30) days following the Applicable Refinery Owner’s timely delivery of such Dispute Notice, the Applicable Refinery Owner and HEP Operating shall, within forty-five (45) days following the Applicable Refinery Owner’s timely delivery of such Dispute Notice, submit any and all matters which remain in dispute to dispute resolution in accordance with the Omnibus Agreement.

6.3 Payment of Amounts No Longer Disputed. If it is finally determined pursuant to this Article 6 that the Applicable Refinery Owner is required to pay any or all of the disputed portion of the Deficiency Payment, the Applicable Refinery Owner shall pay such amount to HEP Operating, together with interest thereon at the Prime Rate, in immediately available funds within ten (10) days of such final determination.

6.4 Contract Quarters Independent. The fact that the Applicable Refinery Owner has exceeded or fallen short of the Minimum Throughput Commitment with respect to any Contract Quarter shall not be considered in determining whether the Applicable Refinery Owner meets, exceeds or falls short of the Minimum Throughput 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 Throughput Commitment with respect to any other Contract Quarter.

ARTICLE 7

RIGHT OF FIRST REFUSAL

The Parties acknowledge the right of first refusal of HollyFrontier with respect to the Applicable Assets as provided in the Omnibus Agreement.

ARTICLE 8

INDEMNITY; LIMITATION OF DAMAGES

8.1 Indemnity; Limitation of Liability. The Parties acknowledge and agree that the provisions relating to indemnity and limitation of liability set forth in Article III of the Omnibus Agreement shall apply to this Agreement. Notwithstanding anything in this Agreement or the Omnibus Agreement to the contrary, and solely for the purpose of determining which of the Applicable Refinery Owner or HEP Operating shall be liable in a particular circumstance, neither the Applicable Refinery Owner nor HEP Operating shall be liable to the other Party for any loss, damage, injury, judgment, claim, cost, expense or other liability suffered or incurred (collectively, “Damages”) by such Party except to the extent that the Applicable Refinery Owner or HEP Operating causes such Damages or owns or operates the assets or other property in question responsible for causing such Damages.

8.2 Survival. The provisions of this Article 8 shall survive the termination of this Agreement.

ARTICLE 9

Neither this Agreement nor any of the rights or obligations hereunder shall be assigned without the prior written consent of the Applicable Refinery Owner (in the case of any assignment by HEP Operating) or HEP Operating (in the case of any assignment by an Applicable Refinery Owner), in each case, such consent is not to be unreasonably withheld or delayed; provided, however, that (i) HEP Operating may make such an assignment (including a partial pro rata assignment) to an Affiliate of HEP Operating without the Applicable Refinery Owner’s consent (but subject to the provision of written notice to the Applicable Refinery Owner), (ii) an Applicable Refinery Owner may make such an assignment (including a pro rata partial assignment) to an Affiliate of such Applicable Refinery Owner without HEP Operating’s consent (but subject to the provision of written notice to HEP Operating), (iii) an Applicable Refinery Owner may make a collateral assignment of its rights and obligations hereunder and/or grant a security interest in its rights and obligations hereunder, and HEP Operating shall execute an acknowledgement of such collateral assignment in such form as may from time-to-time be reasonably requested, and (iv) HEP Operating may make a collateral assignment of its rights hereunder and/or grant a security interest in its rights and obligations hereunder to a bona fide third party lender or debt holder, or trustee or representative for any of them, without an Applicable Refinery Owner’s consent, if such third party lender, debt holder or trustee shall have executed and delivered to such Applicable Refinery Owner a non-disturbance agreement in such form as is reasonably satisfactory to such Applicable Refinery Owner and such third party lender, debt holder or trustee, and such Applicable Refinery Owner executes an acknowledgement of such collateral assignment in such form as may from time to time be reasonably requested. Any attempt to make an assignment otherwise than as permitted by the foregoing shall be null and void. The Parties agree to require their respective successors, if any, to expressly assume, in a form of agreement reasonably acceptable to the other Parties, their obligations under this Agreement.

9.3 Severability. If any provision of this Agreement shall be held invalid or unenforceable by a court or regulatory body of competent jurisdiction, the remainder of this Agreement shall remain in full force and effect.

9.4 Choice of Law. This Agreement shall be subject to and governed by the laws of the State of Delaware, excluding any conflicts-of-law rule or principle that might refer the construction or interpretation of this Agreement to the laws of another state.

12:01 a.m. on November 1, 2015 (the “Effective Time”) to 12:00 midnight on October 31, 2030

The Applicable Refinery Owner shall have the option to extend the Applicable Term beyond the Initial Term for one additional five (5) year period beginning at 12:01 am on November 1, 2030 and ending at 12:00 midnight on October 31, 2035 on the same terms and conditions as in existence for the Initial Term.

1.	The “Feedstock” is light naphtha and heavy naphtha.

2.	The Tolling Fee shall never be less than $.36 per BBL of Feedstock, subject to a one-time potential reduction in the Tolling Fee for the adjustment in paragraph 4 below.

Exhibit C-1

The Tolling Fee, as previously adjusted on a cumulative basis, shall be adjusted on July 1 of each calendar year, commencing July 1, 2017, by an amount equal to a percentage calculated as follows: (A) 0.75 × the change in the PPI as described below, plus (B) 0.25 × the annual HollyFrontier Merit Compensation Adjustment (positive or negative) for such calendar year. The change in the PPI is the upper change in the annual change rounded to four decimal places of the Producers Price Index-Commodities-Finished Goods, (PPI), et al. (“PPI”), produced by the U.S. Department of Labor, Bureaus of Labor Statistics. The series ID is WPUSOP3000– located at xxxx://xxx.xxx.xxx/xxxx/. The change in PPI for each year shall be calculated as follows: annual PPI index (most current year) less annual PPI index (most current year minus 1) divided by annual PPI index (most current year minus 1); provided that the change in PPI in any year shall not be less than one percent (1%) or more than three percent (3%). For the avoidance of doubt, if the change in PPI in any year is less than one percent (1%) it will be rounded up to one percent (1%) and if the change in PPI in any year is greater than three percent (3%) it will be rounded down to three percent (3%). If either index is no longer published, the Parties shall negotiate in good faith to agree on a new index (as applicable) that gives comparable protection against inflation or deflation, and the same method of adjustment for increases or decreases in the new index shall be used to calculate increases or decreases in the Tolling Fee. If the Parties are unable to agree on a new index, a new index will be determined in accordance with the dispute resolution provisions set forth in the Article VIII of Omnibus Agreement, and the same method of adjustment for increases or decreases in the new index shall be used to calculate increases or decreases in the Tolling Fee. The annual HollyFrontier Merit Compensation Adjustment is the company-wide increase (or decrease) in salary for the year in which the adjustment occurs as determined by the HollyFrontier Board of Directors. Examples of the annual Tolling Fee adjustment under various scenarios are as follows:

(1) if the change in PPI is 0% and the HFC Merit Compensation Adjustment is 3.5%, the Tolling Fee adjustment would be (0.75 × 1%) + (0.25 × 3.5%) = 1.625%

(2) if the change in PPI is 2% and the HFC Merit Compensation Adjustment is 2%, the Tolling Fee adjustment would be (0.75 × 2%) + (0.25 × 2%) = 2%

(3) if the change in PPI is 5% and the HFC Merit Compensation Adjustment is 2%, the Tolling Fee adjustment would be (0.75 × 3%) + (0.25 × 2%) = 2.75%

(4) if the change in PPI is 0% and the HFC Merit Compensation Adjustment is -2%, the Tolling Fee adjustment would be (0.75 × 1%) + (0.25 × (-2%)) = 0.25%

At the end of the first four (4) Contract Quarters during the Applicable Term, HEP Operating shall calculate the aggregate operating expenses incurred in the operation of the Applicable Asset (but such calculation shall not include turnaround accruals, capitalized catalyst costs, and extraordinary and non-recurring items of expense that are not reasonably expected to recur in future periods during the Applicable Term) (“OPEX”). In the event that such aggregate OPEX exceed the Assumed OPEX set forth above, (A) the Applicable Refinery Owner shall, within ten (10) days of receiving an invoice from HEP Operating, reimburse HEP Operating for such OPEX incurred during such initial four (4) Contract Quarters in excess of the Assumed OPEX, and (B) from and after the first four (4) Contract Quarters during the Applicable Term, HEP Operating shall increase the Tolling Fee for processing with the Applicable Asset by the amount necessary to recover such aggregate OPEX in excess of the Assumed OPEX for the remainder of the Applicable Term, and the Parties shall execute an amended, modified, revised or updated Exhibit C reflecting such aggregate OPEX as the new Assumed OPEX. In the event that such aggregate OPEX is less than the Assumed OPEX, HEP Operating shall decrease the Tolling Fee by the amount necessary to account for the difference between the Assumed OPEX and such actual OPEX for the remainder of the Applicable Term, and the Parties shall execute an amended, modified, revised or updated Exhibit C reflecting such aggregate OPEX as the new Assumed OPEX.

At the end of the first four (4) Contract Quarters during the Applicable Term, HEP Operating shall determine its aggregate capital expenditures relating to the construction and start-up of the Applicable Asset (“CAPEX”). HEP Operating shall amend and increase the Tolling Fee for the remainder of the Initial Term by the following formula: (aggregate CAPEX/9) ÷ (48,750 × 365.25).

Exhibit C-2

After the first turnaround on the Applicable Asset during the Applicable Term, HEP Operating will calculate its aggregate Turnaround Costs incurred in connection therewith. In the event such aggregate Turnaround Costs for the Applicable Asset exceeds the Accrued Turnaround Cost set forth above then (A) a turnaround surcharge (the “Turnaround Surcharge”) will be added to the Tolling Fee based on each BBL of Feedstock (using the Minimum Throughput Commitment) in order to allow HEP Operating to recover (i) such Turnaround Costs in excess of the Accrued Turnaround Cost plus (ii) a ten percent (10%) return on such excess (the aggregate amount specified in clauses (i) and (ii), the “Turnaround Payment”). Such Turnaround Surcharge shall be paid by the Applicable Refinery Owner to HEP Operating on each BBL of Feedstock processed through the Applicable Asset until the earlier to occur of (i) the expiration of the Applicable Term or (ii) the recovery by HEP Operating of the Turnaround Payment. In addition, the Tolling Fee will be adjusted by the amount necessary to recover the new estimated turnaround expense for the remainder of the Applicable Term (based on the Minimum Throughput Commitment).

If at the end of any calendar month during the Applicable Term the aggregate cost of gas incurred by HEP Operating in connection with the operation of the Applicable Assets exceeds $73,610 (the “Assumed Fuel Gas Cost”), the Applicable Refinery Owner shall promptly pay to HEP Operating an amount equal to the positive difference, if any, of (i) the aggregate cost of fuel gas incurred by HEP Operating in connection with the operation of the Applicable Assets during such calendar month less (ii) the Assumed Fuel Gas Cost.

Naphtha Fractionation Column

Delivery volumes of light naphtha and heavy naphtha feedstock shall be determined by the BBL unit of measure with the metered data stored at PI Tag FI14381.daca.pv for light naphtha and FI14382.daca.pv for heavy naphtha.

Delivery volumes of isopentane, XXXX feed, intermediate naphtha and reformer feed shall be determined by the BBL unit of measure with the metered data stored at tags FC14578.pida.pv, FC14592.pida.pv, FC14612.pida.pv and reformer feed at tag FY14467.daca.pv.¹

1.	The expected conversion ratio of light naphtha and heavy naphtha to isopentane, XXXX feed, intermediate naphtha and reformer feed is 1 BBL to 1 BBL.

Examples of the reduction in Tolling Fees and the Minimum Throughput Commitment for non-Force Majeure Events that may occur under Section 2.1(d)(1) and (2) of the Agreement are as follows:

Section 2.1(d)(1) – The Minimum Throughput Commitment of 48,750 BPD of light naphtha and heavy naphtha converts to 48,750 BPD of isopentane, XXXX feed, intermediate naphtha and reformer feed (the “NFC Products”) based on a Conversion Ratio of 1 to 1. If the NFC Products produced are 46,312.5 BPD (95%) or more, then there would be no adjustment to the Tolling Fee.

Example A: If the Minimum Throughput Commitment of Feedstock is delivered by the Applicable Refinery Owner to HEP Operating at the Applicable Asset for a particular Contract Quarter and the NFC Products produced by HEP Operating for such Contract Quarter is on average 43,875 BPD (90% of the Conversion Ratio for the Minimum Through Commitment), the Tolling Fee for such Contract Quarter would be reduced by 5% from $.36 per BBL (100%) to $.342 per BBL (95%).

Example B: If the Minimum Throughput Commitment of Feedstock is delivered by the Applicable Refinery Owner to HEP Operating at the Applicable Asset for a particular Contract Quarter and the NFC Products produced by HEP Operating for such Contract Quarter is on average 41,437.5 BPD (85% of the Conversion Ratio for the Minimum Throughput Commitment), the Tolling Fee for such Contract Quarter would be reduced by 10% from $.36 BBL (100%) to $.324 per BBL (90%).

Exhibit F-1

Section 2.1(d)(2) – If the Aggregate Capacity of any Applicable Asset for any Contract Quarter is less than the Minimum Throughput Commitment for such Applicable Asset for such Contract Quarter, then the Minimum Throughput Commitment for such Applicable Asset for such Contract Quarter will be reduced by a percentage equal to (A) 100% minus (B) the percentage represented by the ratio of (i) the Aggregate Capacity for such Applicable Asset for such Contract Quarter to (ii) the Minimum Throughput Commitment for such Applicable Asset for such Contract Quarter.

Example A: If the Aggregate Capacity of any Applicable Asset for a Contract Quarter is on average 46,312.5 BPD (95% of the Minimum Throughput Commitment for such Contract Quarter), then the Minimum Throughput Commitment for such Contract Quarter would be reduced to 46,312.5 BPD of light naphtha and heavy naphtha (95% of the Minimum Throughput Commitment for such Contract Quarter).

Example B: If the Aggregate Capacity of any Applicable Asset for a Contract Quarter is on average 43,875 BPD (90% of the Minimum Throughput Commitment for such Contract Quarter), then the Minimum Throughput Commitment for such Contract Quarter would be reduced to 43,875 BPD of light naphtha and heavy naphtha (90% of the Minimum Throughput Commitment for such Contract Quarter).
