Section 4.

Title Matters.

4.1 Purchase Price Adjustments for Defective Interests.

(a) Notice of Defective Interest. Buyer shall give the Company written “Notice of Defective Interests” as soon as possible but no later than five (5) business days before the Closing Date, (the “Defect Notice Date”). This notice must be in writing and satisfy the following conditions precedent: (i) a description of each Defective Interest; (ii) the basis for each Defective Interest, and, if the basis is derived from any document, a copy of such document (or pertinent part thereof) shall be attached or if the basis is derived from any gap in PGR’S chain of title, the documents preceding and following the gap shall be attached; (iii) the Allocated Value of the affected PGR Lease; and (iv) Buyer’s good faith estimate of the Defect Value and the computations upon which Buyer’s estimate is based. If a PGR Lease has not been given an Allocated Value or the Allocated Value of PGR Lease is Fifty Thousand Dollars ($50,000) or less, the Company shall be deemed to have Defensible Title to such PGR Lease.

(b) Defect Adjustments.

(1) If a PGR Lease is a Defective Interest, the Purchase Price will be reduced under Section 2.3(c)(ii) by the corresponding Defect Value (which reduction is called a “Title Defect Adjustment”) unless prior to the Closing Date:

(A) the Company either cures the Title Defect to Buyer’s reasonable satisfaction or elects to cure the Title Defect no later than 90 days after Closing; or

(B) Buyer elects to waive the relevant Title Defect.

The Purchase Price shall be adjusted pursuant to Section 2.3 for Defective Interests only if the aggregate of all Defect Values, net of the Value of all Interest Additions, for all of the PGR Leases exceeds 3% of the Purchase Price (the “Title Threshold Amount”).

(2) If a PGR Lease is a Defective Interest for which an adjustment to the Purchase Price would otherwise be required and the Company elects to cure the defect after Closing, Buyer and the Company shall at Closing in good faith agree to place a portion of the Purchase Price into an escrow account (the “Escrow Account”) established pursuant to an escrow agreement in substantially the form attached hereto as Exhibit F (the “Escrow Agreement”) with Xxxxx Fargo Bank or another mutually acceptable financial institution (“Escrow Agent”) until Buyer’s receipt of the Company’s curative materials. The amount of the Escrow Account shall be the aggregate of all Defect Values net of the Value of Interest Additions.

-16-

Exhibit 10.17

(3) If the Company has elected to cure a Title Defect and such Title Defect is cured on or before 90 days after Closing, the Escrow Agent shall distribute to the Company, immediately upon Buyer’s receipt of curative materials reasonably satisfactory to Buyer, the amount placed in the Escrow Account with respect to such Title Defect (and any account interest accrued thereon).

(4) If the Company does not cure a Title Defect within the 90 day time period, Buyer shall be entitled to an amount equal to the corresponding Defect Value as provided in Section 4.1(b)(1).

(5) If Buyer disputes the adequacy of the Company’s curative material, Buyer must invoke the dispute resolution mechanism set forth in Section 4.3 within 30 days after receipt thereof. If the parties dispute the Defect Value of a Defective Interest which is not timely cured, then the provisions of Section 4.3 shall apply.

4.2 Interest Additions. Promptly on discovery, Buyer or the Company, whichever is the discovering party shall notify the other of any interest that entitles PGR to receive more than the NRI set forth in Exhibit A, or obligates PGR to bear costs and expenses in an amount less than the WI set forth in Exhibit A (collectively, “Interest Additions”). The party who discovers Interest Additions must give the other party written notice of Interest Additions as soon as possible, but in no event later than on or before two (2) business days prior to Closing. This notice must be in writing and must include (i) a description of each Interest Addition, (ii) the basis for each Interest Addition, (iii) the Allocated Value of the PGR Lease affected by the Interest Addition, and (iv) the value of the Interest Addition or the amount by which the notifying party believes the Allocated Value of the PGR Lease has been increased by the Interest Addition (“Value of Interest Addition”) and the computations upon which such party’s belief is based. The Value of Interest Addition shall be determined by the parties in good faith taking into account all relevant factors and the Purchase Price will be increased in accordance with Section 2.3 by such an amount (“Interest Addition Adjustment”) if the aggregate of all Interest Addition Adjustments, net of the aggregate of all Defect Values, exceeds One Hundred Fifty Thousand Dollars ($150,000.00) (the “Addition Threshold Amount”).

4.3 Title Dispute Resolution. The parties agree to resolve disputes concerning the following matters pursuant to this Section: (i) the existence and scope of a Title Defect, (ii) the Defect Value of that portion of the PGR Lease affected by a Title Defect, (iii) the Value of an Interest Addition, and (iv) the adequacy of the Company’s Title Defect curative materials (the “Title Disputed Matters”). The parties agree to attempt to initially resolve all disputes through good faith negotiations. If the parties cannot resolve disputes regarding items (i), (ii) or (iii) on or before fifteen (15) days after Closing, the Disputed Matters will be finally determined by binding arbitration pursuant to Section 11.7 with an independent arbitrator mutually acceptable to the parties or, if none, with a panel of three arbitrators appointed pursuant to Section 11.7 who are qualified by education, knowledge and experience with title defects affecting the types of properties which are subject to the disputed Title Defect and have a minimum of ten years experience with such types of defects and properties. The arbitrator(s) shall take into account the factors set forth in the definition of “Defect Value” and employ such independent attorneys, petroleum engineers and/or other consultants as deemed necessary. On or before 60 days after Closing, Buyer and the Company shall present their respective positions in writing to the Arbitrator(s), together with such evidence as each party deems appropriate. The Arbitrator(s) shall be instructed to resolve the dispute through a final decision within 90 days after Closing and the final decision may be reflected in a final settlement statement. If the parties cannot resolve disputes regarding Section 4.3 (iv) within five (5) days after Buyer’s receipt of the Company’s Title Defect curative materials, the dispute will similarly be finally determined by binding arbitration pursuant to Section 11.7 and this Section 4.3 but the arbitration hearing shall be held no later than fifteen (15) days after Buyer’s receipt of the Company’s Title Defect curative materials with a final decision no later than twenty-five (25) days after Buyer’s receipt of the Company’s Title Defect curative materials and the final decision shall similarly be reflected in a final settlement statement.

4.4 Termination. Notwithstanding the foregoing, if the aggregate of all Defect Values, net of the Value of all Interest Additions, for all of the PGR Leases exceeds Ten Percent (10%) of the Purchase Price set forth in Section 2.3, the Company or Buyer may terminate this Agreement upon written notice to the other party delivered no later than 5:00 p.m. on the day before the scheduled Closing Date; provided however that Buyer, at its sole discretion, may elect to waive all or any portion of any Title Defect to reduce the aggregate Title Defect Values below such percentage in which event this Agreement shall remain in full force and effect. If a party has elected to exercise this right of termination and the other party does not agree that the right of termination has been triggered, the objecting party shall notify the other party on or before 5:00 p.m. on the scheduled Closing Date and, thereafter, unless the parties are able to resolve the dispute within three (3) days after the originally scheduled Closing Date, the matter shall be determined by binding arbitration pursuant to Section 11.7, before a panel of arbitrators meeting the qualifications set forth in Section 4.3, and with the arbitrators to be appointed and the arbitration to be conducted within the time frame provided in Section 4.3 for Title Disputed Matters other than those relating to Title Defect curative materials. In the event of an objection over whether the right to terminate has been triggered, the Closing shall be extended until three (3) business days after the dispute is resolved by parties as provided in this Section 4.4 or the parties receive a final decision from the arbitrators, whichever is applicable.

4.5 Preferential Rights. The Company has no knowledge of any preferential rights of third parties applicable to the transaction contemplated by this Agreement. Nonetheless, if prior to Closing, the Company or Buyer becomes aware of any claims asserted by third parties that preferential rights are applicable to this transaction, it shall promptly notify the other party of such fact. In such event, the Company agrees (a) to join in the defense of such claim, (b) to present the best defense possible, (c) to deliver to Buyer copies of such records, documents, files and other data which it possesses pertaining to such claim, and (d) to take such actions or do, or cause to be done, all things necessary, proper or advisable, which Buyer may reasonably and lawfully request in defense against such claims.
