Pre-Construction Build Out for the Baker Acreage

Wildcat shall extend the Initial Facilities and construct additional pipelines, gathering lines, pumps, terminals, equipment and related connection facilities, equipment and other personal property and fixtures (“Connection Facilities”) that are necessary to connect the Approach designated central production facility constructed or to be constructed by Approach (“CPF”) (and receive into the Initial Facilities all of the production delivered by Approach from such CPF) located on (or allocable to) the Dedicated Interests known as the “Baker Leases,” as such area is specified in Exhibit “D” attached hereto (“Baker Lease Gathering Line”). If Wildcat fails to complete construction, installation and connection of the Baker Lease Gathering Line within [REDACTED]* following date of closing under the EPA, then Wildcat shall provide trucking services to Approach to the Midway trucking terminal or such other mutually-agreed delivery point [REDACTED]* for all for all Dedicated Oil produced from any wells located on (or allocable to) the Baker Leases for a period of the sooner of [REDACTED]*. Notwithstanding the foregoing, if at the end of such [REDACTED]* period, Wildcat still has not built and completed the Baker Lease Gathering Line sufficient to receive all of such production, and actually connected the same to Approach’s designated CPF located on (or allocable to) the Baker Leases, then the Baker Leases, without further action or notice by or to any party, automatically shall be deemed released from dedication (and Wildcat shall execute and deliver such instruments, agreements and documentation as reasonably requested by Approach to further evidence this release from dedication (including, without limitation, (1) an amendment to this Agreement to reflect such release, and (2) an amendment to the Memorandum of Dedicated Area described in Section 8 above, to reflect such release), and Approach shall owe no further duty or obligation to Wildcat with regard to such released acreage.

[REDACTED]*.

Wildcat will construct and install the Baker Lease Gathering Line under the terms of a mutually agreed Authorization for Expenditure for the Baker Lease Gathering Line agreed to by Approach and Wildcat.

Notwithstanding the foregoing, the time frame for commencing, pursuing and completing the construction and installation of the Baker Lease Gathering Line shall be extended by the number of days in any applicable force majeure period that occurs during the construction phase (subject to the limitations regarding force majeure set forth in Exhibit “C”).

4

Construction at Approach’s Option (Prior to a Construction Trigger)

In the event that Approach desires that Wildcat construct Connection Facilities that are necessary to receive Dedicated Oil prior to the occurrence of a Construction Trigger (as defined below), Approach shall provide notice to Wildcat of same (the “Approach Request”), and the parties shall have 30 days following delivery of such notice to review the scope of the project and to agree upon a budget to form the basis of the “Capital Recovery Rate” as provided below.

Upon the completion of such 30 day review period, Wildcat shall either (i) provide Approach with a notice of Wildcat’s acceptance (the “Acceptance Notice”) to immediately commence construction and thereafter diligently pursue to completion the construction of such Connection Facilities (and the extension of the Initial Facilities) (the “Requested Connection Facilities”), or (ii) provide notice to Approach that Wildcat declines (“Decline Notice”) to construct such Requested Connection Facilities. If Wildcat provides Acceptance Notice and fails to complete construction of such Requested Connection Facilities within one hundred twenty (120) days following delivery of its Acceptance Notice), then Wildcat shall provide trucking services to Approach at [REDACTED]* for all oil production produced from the CPF or any wells located within the area specified by the Approach Notice for a period of the sooner of (A) twelve (12) months from the date of the Acceptance Notice, or (B) the date Wildcat completes the Requested Connection Facilities and connects to the designated CPF in the area specified by the Approach Request.

The Requested Connection Facilities to be constructed by Wildcat, will connect to the designated CPF. Upon completion of the Requested Connection Facilities to the applicable CPF, and during the continuing operation of the Requested Connection Facilities, [REDACTED]*.

Notwithstanding the foregoing, the time frame for completing the construction and installation of the Requested Connection Facilities above shall be extended by the number of days in any applicable force majeure period that occurs during the construction phase (subject to the limitations regarding force majeure set forth in Exhibit “C”).

The failure by Wildcat to timely deliver either an Acceptance Notice or a Decline Notice within the 30-day period specified above shall be deemed to be, for purposes hereof, an election by Wildcat to deliver a Decline Notice (and the following provisions shall apply with regard thereto). If Wildcat delivers a Decline Notice with respect to the Approach Request, Wildcat shall provide trucking services to Midway trucking terminal or other mutually-agreed delivery point at [REDACTED]* for all oil production produced from any wells connected to a CPF and located within a five (5) mile radius of the CPF that is the subject of such Approach Request, for twelve (12) months from the date of the Decline Notice.

5

Following the construction and installation of the Requested Connection Facilities, and during the continuing operation of the Requested Connection Facilities, Approach shall pay [REDACTED]*.

Construction After the Occurrence of a Construction Trigger

At any time during the Term, Approach shall give written notice to Wildcat whenever its aggregate crude oil production from two (2) or more wells (not already connected to a CPF that is already connected to the Initial Facilities) within a five (5) mile radius of a CPF has averaged in the aggregate at least [REDACTED]* barrels of crude oil production per day for a period of at least 45 consecutive days (the “Construction Trigger”).

Upon the occurrence of a Construction Trigger and delivery of such notice (together with a copy of Approach’s internal production volume reports, confirming such Construction Trigger), the parties shall have 30 days to review the scope of the project. Upon the completion of such 30 day period, Wildcat shall either (i) provide Approach with an Acceptance Notice to immediately commence construction to extend the Initial Facilities and construct and install, at Wildcat’s sole cost and expense, such additional Connection Facilities, that are necessary to connect and receive all of the production specified in the Construction Trigger notice into the Initial Facilities (the “Trigger Gathering Line”), or (ii) provide a Decline Notice to Approach declining to construct such Trigger Gathering Line. If Wildcat provides an Acceptance Notice and fails to complete construction of such Trigger Gathering Line within one hundred twenty (120) days following delivery of its Acceptance Notice), then Wildcat shall provide trucking services to the Midway trucking terminal or such other mutually-agreed delivery point [REDACTED]* for all oil production produced from any wells located within the area specified by the Construction Trigger for a period of the sooner of (A) twelve (12) months from the date of the Acceptance Notice, or (B) the date Wildcat completes the Trigger Gathering Line and connects to the designated CPF in the area specified by the Construction Trigger. Notwithstanding the foregoing, if at the end of the twelve month period described in subpart (A) above, Wildcat still has not built and completed the Trigger Gathering Line sufficient to receive all of such production, and actually connected the same to Approach’s designated CPF specified in the Construction Trigger, then the Trigger Release Area (defined below), without further action or notice by or to any party, automatically shall be deemed released from dedication (and Wildcat shall execute and deliver such instruments, agreements and documentation as reasonably requested by Approach to further evidence this release from dedication (including, without limitation, (1) an amendment to this Agreement to reflect such release, and (2) an amendment to the Memorandum of Dedicated Area described in Section 8 above, to reflect such release), and Approach shall owe no further duty or obligation to Wildcat with regard to such released acreage.

6

“Trigger Release Area” shall be defined to include the Dedicated Area located within a five-mile radius of the applicable or proposed CPF for the proposed Trigger Gathering Line, save and except that in no event during the Term of this Agreement (and subject to Section 1.3 of the Original Agreement) shall there be released from dedication under this paragraph in connection with a Trigger Gathering Line of (i) all or any portion of the approximately 40,000 acres subject to dedication under the Original Agreement (other than a release or termination described in the other provisions of the Original Agreement and other than with regard to the Block 45 Area, as described in subpart (b) below), or (ii) the approximately 10,000 acres constituting the Baker Lease (other than as described in subpart (a) below, and other than a release or termination described in the other provisions of the Original Agreement); provided, however, that (a) the approximately 10,000 acres of the Baker Lease shall be subject to dedication release and included in the Trigger Release Area, but only as provided above for Wildcat’s failure to perform its obligations with respect to the Baker Lease Gathering Line, and such default results in a forfeiture and release of the Baker Leases, as provided above; and (b) the acreage included in Block 45 south extension area more particularly described on Exhibit “D” attached hereto (the “Block 45 Area”) shall be subject to dedication release and included in the Trigger Release Area, but only to the extent that a Construction Trigger occurs for such Block 45 Area and Wildcat (x) provides a Decline Notice; or (y) provides an Acceptance Notice, but after delivering such notice fails to perform and complete the Requested Connection Facilities for the Block 45 Area within the deadlines and the other terms and conditions provided for Requested Connection Facilities, thereby resulting in a forfeiture and release of the Block 45 Area, as applicable.

Notwithstanding the foregoing, the time frame for completing the construction and installation of the Trigger Gathering Lines above shall be extended by the number of days in any applicable force majeure period that occurs during the construction phase (subject to the limitations regarding force majeure set forth in Exhibit “C”).

The failure by Wildcat to timely deliver either an Acceptance Notice or a Decline Notice within the 30-day period specified above shall be deemed to be, for purposes hereof, an election by Wildcat to deliver a Decline Notice (and the following provisions shall apply with regard thereto). If Wildcat delivers a Decline Notice with respect to the Construction Trigger, then (i) Wildcat shall provide trucking services to the Midway trucking terminal or such other mutually-agreed delivery point [REDACTED]* for all oil production produced from any wells connected to a CPF and located within a five (5) mile radius of the CPF that is the subject of such Construction Trigger, for up to twelve (12) months from the date of the Decline Notice, and (ii) the Trigger Release

7

Area, without further action or notice by or to any party, automatically shall be deemed released from dedication (and Wildcat shall execute and deliver such instruments, agreements and documentation as reasonably requested by Approach to further evidence this release from dedication (including, without limitation, (1) an amendment to this Agreement to reflect such release, and (2) an amendment to the Memorandum of Dedicated Area described in Section 8 above, to reflect such release), and Approach shall owe no further duty or obligation to Wildcat with regard to such released acreage.

1.7 New Section 11. A new Section 11 is hereby added to the Original Agreement, which shall read as follows:

11. JPE GUARANTY. As a condition precedent to Approach’s obligations hereunder, (i) JPE joins in this Agreement to evidence its agreement to unconditionally guaranty the payment, performance and satisfaction of all of the obligations and liabilities of Wildcat under the Original Agreement, as amended by this Amendment, and to the extent arising on or after the date of the closing(s) under the EPA, as applicable (including, without limitation, the additional construction and transportation obligations set forth herein), and (ii) contemporaneous with the execution and delivery of this Amendment, JPE agrees to execute and deliver to Approach a Guaranty Agreement, in substantially the form attached hereto as Exhibit “G”.

1.8 New Section 12. A new Section 12 is hereby added to the Original Agreement, which shall read as follows:

12. PREFERENCE ON PIPELINE CAPACITY; LOCATION OF CPFS.

Wildcat hereby grants to Approach the right of first priority and a first preference for crude oil capacity on (and rights to have its Dedicated Oil gathered or transported across) the Initial Facilities, as well as any extension and additions to the Initial Facilities, together with any other pipelines, gathering lines, lateral lines or related facilities owned or operated by Wildcat or its affiliates located in the Dedicated Area (collectively, the “Facilities”) for any and all Dedicated Oil delivered by Approach under this Agreement; and to the extent Wildcat is then accepting crude oil owned or controlled by any person or entity other than Approach for purchase, transportation or gathering across the Facilities (“Non-Approach Crude”), Wildcat shall curtail such volumes of Non-Approach Crude as may be necessary for Wildcat to accept and receive all volumes of Dedicated Oil delivered by Approach under this Agreement. If for any reason (other than as may be excused by force majeure, as provided in this Agreement), Wildcat is unable or unwilling to accept any volumes of Dedicated Oil made available by Approach, then Wildcat shall provide trucking services at the lower of [REDACTED]* for all such Dedicated Oil that Wildcat fails or refuses to take, and such trucking services shall be Approach’s sole and exclusive remedy with regard to the breach of the priority and preference covenants set forth in this Section 12. If, however, during any temporary period of inspection, repair or maintenance Wildcat is unable to accept any volumes of Dedicated Oil made available by Approach from a CPF that is connected to the Facilities, then Wildcat shall provide trucking services until such time as service is restored.

8

Notwithstanding anything stated in this Agreement to the contrary, Approach shall have the exclusive right and discretion with regard to establishing the locations of any CPF for the Dedicated Oil within the Dedicated Area.

For the sake of clarity, to the extent that Wildcat breaches its trucking service, priority and preference with regard to Facility Capacity, or release obligations contemplated or set forth in this Agreement, the same shall be construed as a “material” breach or default of its obligations under this Agreement by Wildcat, including, without limitation, for purposes of the provisions set forth in Section 10 of Exhibit “C” attached hereto.

1.9 New Section 13. A new Section 13 is hereby added to the Original Agreement, which shall read as follows:

13. SALE OF CRUDE OIL THAT IS TRUCKED.

Notwithstanding the provisions of Section 4 and Section 5 above, and notwithstanding the provisions of Exhibit A and Section 6 of Exhibit C attached hereto, when Wildcat provides the trucking services to Approach contemplated under this Agreement, then: (i) the Receipt Point for all Dedicated Oil trucked shall be deemed to be the inlet flange on the delivery truck used to receive and transport such Dedicated Oil (and title to, and risk of loss of, such crude oil shall be deemed to pass at to Wildcat at such point), and (ii) the trucking costs paid by Approach in accordance with the terms of such provisions of this Agreement, unless otherwise specified herein, shall be the equivalent of the [REDACTED]*.

1.10 Exhibit A – Pricing Detail. Paragraphs A and B to Exhibit A to the Original Agreement are hereby and restated in their entirety, to read as follows (and new Paragraph C below is hereby added to Exhibit A to the Original Agreement):

1.11 [REDACTED]*.

1.12 Exhibit D – Dedicated Acreage. The acreage dedication map shown on Exhibit “D” to the Original Agreement shall be deleted and replace the map in its entirety with the map attached hereto as Exhibit “D”.
