| 1. | Minimum Volume Commitment.  Subject to any Force Majeure Event and any Enumerated Circumstance (each as defined below), during each month during the Term (as defined below), PVOG agrees to deliver on an aggregate average daily basis at least 8,000 barrels per day of crude oil pursuant to one of the methods set forth in this Agreement (such amount, the "Commitment").  For the avoidance of doubt, the Commitment shall be determined on a monthly basis. |

|    |                                                                                                                                                                                                                                                                                                                                                                                                      |
|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| a. | In the event that PVOG's aggregate daily deliveries hereunder during any monthly period are less than the Commitment for that month, and no Over-Delivery Credits are then outstanding, then a deficiency (the "Deficiency") shall exist.  PVOG will be obligated to pay to Republic an amount for each deficient barrel equal to the Transportation Deduction (such amount, the "Deficiency Fees"). |

|    |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |
|----|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| b. | Republic shall invoice PVOG monthly for any Deficiency Fees.  In the event that PVOG ships volumes in excess of the Commitment in any given month, PVOG shall be entitled to a credit against any Deficiency Fees assessed by Republic in the subsequent twelve (12) months, or any Deficiency Fees paid by PVOG in the preceding twelve (12) months, in an amount equal to the surplus barrels multiplied by the Transportation Deduction (each, an "Over-Delivery Credit").  Over-Delivery Credits shall first be applied to any Deficiency Fees paid by PVOG during the preceding twelve (12) months, and shall be credited during the month corresponding to the applicable Over-Delivery Credit. |

|    |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
|----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| c. | Over-Delivery Credits shall be applied only to volumes shipped in accordance with Article I, Section 2 below in excess of PVOG's Commitment for that month and shall be applied at all times on a first-in, first-out basis, so that the oldest month's Over-Delivery Credit is fully utilized before application of any subsequent month's Over-Delivery Credit.  Over-Delivery Credits shall expire if not used by the end of the twelve (12) month period following the month during which such Over-Delivery Credit was created.  At the end of the Term, any remaining unexpired or unutilized Over-Delivery Credits shall expire on the last day of the Term and will not be valid for use against any future shipments on KMCC. |

|    |                                                                                                                                                                          |

| a. | PVOG Buy-Sell Volumes Delivered to KMCC.  All crude oil volumes delivered and sold by PVOG to Republic at the PVOG Delivery Point (as defined below) and redelivered at a Republic Delivery Point (as defined below) pursuant to the provisions of Article II of this Agreement shall count toward the Commitment. |

|    |                                                                                                                                                                                                                                                                                                                             |

| 1. | Quantity.  Each month, PVOG shall provide Republic with written notice as to the nominations and quantity of volumes of crude oil it expects to tender for purchase by Republic at the PVOG Delivery Point during the following month (the "Shipment Schedule").  The Shipment Schedule shall also set forth the applicable Republic Delivery Point(s) to which PVOG desires that Republic re-deliver the crude oil.  PVOG may nominate volumes in excess of the Commitment.  PVOG shall deliver and sell to Republic, and Republic shall receive and purchase from PVOG, the quantity tendered by PVOG up to the Commitment.  To the extent PVOG timely nominates and tenders more than the Commitment, Republic shall receive and purchase from PVOG such excess, but only to the extent that Republic and KMCC, as applicable, have physical capacity in excess of other commercial commitments sufficient to receive such excess. |

| 2. | Contaminated Oil.  Should PVOG deliver crude oil to Republic that fails to meet the Specifications (other than if such failure is attributable to third party volumes commingled with PVOG's crude oil while in Republic or Republic Midstream, LLC's (or any applicable successor) control and possession), then PVOG shall pay or reimburse all costs and expense incurred by Republic for the removal, disposal or treatment of PVOG's Off-Spec Product and any damage to KMCC or associated tankage and facilities resulting from such Off-Spec Product, including, but not limited to, damage to crude oil in tankage due to commingling of PVOG's Off-Spec Product in Republic's tankage at the DeWitt Station. If PVOG desires to tender crude oil outside of the Specifications (excluding any crude oil tendered whereby the nonconformance is attributable to third party volumes commingled with PVOG's crude oil while in Republic or Republic Midstream, LLC's (or any applicable successor) control and possession), such product must first be approved by Republic at Republic's sole discretion.  If any additional or special equipment is required to measure, store or transport this product, PVOG will be responsible for these additional costs and also the costs of necessary cleaning and restoration to return the equipment to its previous operating condition. |

| f. | Extension of Term.  For each period that performance was suspended in excess of fourteen (14) days for a claimed Force Majeure Event or Enumerated Circumstance ("Suspension Period"), the Term of this Agreement shall be extended by the cumulative number of days from all Suspension Periods over the Term ("FM Extension Period"), so that the Parties may complete the performance that would otherwise have occurred but for the suspension.  If the last day of the FM Extension Period ends on a day that is not the last day of a calendar month, then PVOG may elect at its option to continue selling volumes protected from proration up to its Commitment for the remaining days in the then current calendar month, subject to Republic's nomination and scheduling policies, for the sole purpose of providing PVOG with the ability to conform to standard monthly crude oil marketing contracts. |

| a. |  In consideration of Republic entering into this Agreement, PVOG Guarantor unconditionally and irrevocably guarantees to Republic the due and punctual performance of each of PVOG's obligations to Republic pursuant to this Agreement (such obligations, the "Guaranteed Obligations"), as and when provided in this Agreement.  PVOG Guarantor shall be liable for the payment of the Guaranteed Obligations (if not timely paid by PVOG), as set forth in this Article V, as a primary obligor, and not as a mere surety. The guaranty in this Article V is a continuing guaranty of payment and performance and not a guaranty of collection.  If PVOG fails to pay the Guaranteed Obligations when due, or any part thereof, PVOG Guarantor shall, on written demand and without further notice of nonpayment, or any other notice whatsoever, pay the amount due and payable thereon to Republic as required per the terms of this Agreement, and it shall not be necessary for Republic, in order to enforce such payment or performance by PVOG Guarantor, first to institute suit or pursue or exhaust any rights or remedies against PVOG or others liable for such payment or performance.  PVOG Guarantor's liability hereunder shall be limited to the payment or performance obligations expressly required of PVOG under this Agreement. |

| c. | In the event any payment by PVOG or any other person or entity (other than PVOG Guarantor) to Republic in respect of the Guaranteed Obligations is held to constitute a preference, fraudulent transfer or other voidable payment under any bankruptcy, insolvency or similar applicable law, or if for any other reason, Republic is required to refund such payment or pay the amount thereof to any other creditor, such payment by PVOG or such other person or entity to Republic shall not constitute a release of PVOG Guarantor from any liability hereunder, and the guaranty under this Article V shall continue to be effective or shall be reinstated (notwithstanding any prior release, surrender or discharge by Republic of this Guaranty or of PVOG Guarantor), as the case may be, with respect to, and the guaranty under this Article V shall apply to, any and all amounts so refunded by Republic or paid by Republic to another person or entity (which amounts shall constitute part of the Guaranteed Obligations).  Notwithstanding the foregoing, the obligations of PVOG Guarantor hereunder at any time shall be limited to the maximum amount as will result in the obligations of PVOG Guarantor hereunder not constituting a fraudulent transfer or conveyance to the extent applicable to this Agreement and the obligations of PVOG Guarantor hereunder. |
