Exhibit A
Dispute Resolution Procedures

ALTERNATIVE DISPUTE RESOLUTION (ADR)

Except as otherwise expressly stated in the Agreement, any dispute arising out of or relating to this Agreement shall be resolved in accordance with the procedures specified in Article I of this Exhibit A. The prevailing Party in any legal proceeding or alternative dispute resolution brought to enforce any provision of this Agreement shall be entitled to recover against the non-prevailing Party the reasonable attorneys’ fees, court costs, and other expenses incurred by the prevailing Party, including all costs and expenses and attorneys’ fees incurred as a result of arbitration of the dispute.

Article I
Formal ADR/Arbitration

1.             Negotiations Between Executives

The Parties shall attempt in good faith to resolve any dispute arising out of or relating to this Agreement promptly by negotiation between executives who have authority to settle the controversy and who are at a higher level of management than the persons with direct responsibility for the matter in dispute. Any Party may give the other Party written Notice of any dispute not resolved in the normal course of business. Within fifteen (15) Days after delivery of the Notice, the receiving Party shall submit to the other a written response. The Notice and the response shall include a statement of each Party’s position and a summary of arguments supporting that position, and the name and title of the executive who will represent that Party and of any other Person who will accompany the executive. Within thirty (30) Days after delivery of the disputing Party’s Notice, the executives of both Parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve the dispute. All reasonable requests for non-privileged and/or non-proprietary information made by one Party to the other will be honored.

All negotiations pursuant to this clause shall be considered confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

Notwithstanding the foregoing, nothing contained in this Agreement shall limit or restrict in any way the right or power of a Party at any time (A) to commence and prosecute a proceeding for a preliminary or temporary injunction or other temporary order pending mediation or arbitration under this Agreement (i) to restrain a Party from breaching this Agreement, or (ii) for specific enforcement of this Exhibit A, or (B) to consult with the other Party in an attempt to negotiate a resolution of the dispute.

The Parties agree that any legal remedy available to them with respect to a breach of this Article I will not be adequate and that, in addition to all legal remedies, each Party is entitled to an order specifically enforcing this Exhibit A.

2.             Mediation

If the dispute has not been resolved by negotiation described in Subsection 1. of this Article I. within forty five (45) Days after the receipt of the disputing Party’s Notice by the other Party, the Parties shall endeavor to settle the dispute by mediation conducted in the English language under the then current Center For Public Resources’ CPR Model Mediation Procedure for Business Disputes. The mediation will be conducted at a site agreed upon by the Parties. Each Party shall be responsible for its own attorney’s fees and costs, provided that the prevailing Party shall be entitled to recover its attorneys’ fees and costs incurred during mediation if the mediation is unsuccessful and the Parties proceed with arbitration.

3.             Arbitration

If a dispute or controversy shall arise between the Parties with respect to any matter covered by this Agreement that has not been resolved pursuant to either Subsections 1. or 2. above, either Party involved in such controversy shall have the option of submitting the matter to arbitration in the English language pursuant to the guidelines set forth below. Demand and submission to arbitration as provided in this Agreement must, unless otherwise agreed, be made to the other Party in writing by the requesting Party within the later of (A) ten (10) Days after negotiations and mediation held pursuant to Subsections 1. and 2. above have failed, and (B) sixty (60) Days following the effective date of Notice of the dispute or controversy. The failure to timely submit the matter to arbitration shall constitute a waiver of the Parties to submit their dispute to arbitration. If submitted to arbitration, the arbitration shall be binding on the Parties and the dispute shall be settled in accordance with the guidelines below.

Any controversy or claim arising out of or relating to this Agreement, or the breach hereof, or the commercial or economic relationship of the Parties, shall, if an election is so made pursuant to this Agreement, be settled by arbitration in accordance with the AAA Rules, and judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. The arbitration shall be administered by the AAA. The AAA Rules are incorporated into this Agreement and, as amended from time to time by the AAA, shall establish the procedures for any arbitration brought under this Agreement, except as modified by the following provisions:

(A)                          Monetary Limitations. Any Party may initiate arbitration in accordance with the terms of this Agreement and the AAA Rules irrespective of the amount in controversy.

(B)                          Number of Arbitrators. If a dispute involves an amount in controversy of $100,000 or less, there shall be one (1) arbitrator. If a dispute involves an amount

2

in controversy in excess of $100,000 or a request for preliminary injunction, there shall be three (3) arbitrators.

(C)                               Arbitrators’ Qualifications and Selection. For disputes involving three (3) arbitrators, each Party involved in the arbitration shall have the right to submit to the other Party involved in the proceeding a proposed list of five (5) qualified arbitrators. Each Party must select one of the proposed candidates nominated by the other Party within ten (10) Days after receiving the list of candidates. The arbitrators selected by the Parties shall then select a third qualified arbitrator to act as chairman. Each arbitrator shall be fully active in his or her profession or occupation. All arbitration proceedings shall be conducted in Tulsa, Oklahoma. If the dispute will be heard by three (3) arbitrators, the arbitrator to be selected by the Party-appointed arbitrators shall be a lawyer experienced in arbitrating large commercial issues of the kind or type similar to those being disputed by the Parties. For disputes involving only one (1) arbitrator, the arbitrator shall be selected in the manner prescribed by the AAA Rules. Should the Parties fail to timely join in the appointment of the arbitrators or should more than two (2) Parties be involved in the arbitration, the arbitrators shall be appointed in accordance with the AAA Rules. The arbitrators shall be fully compensated in accordance with their normal hourly or per diem rates for all time spent by them in connection with the arbitration proceeding, and pending final award, their compensation and expenses shall be advanced equally between or among all Parties participating in the arbitration. Each arbitrator, including those nominated by a Party, shall conduct himself or herself as a neutral, and once each arbitrator has been appointed, there shall be no substantive ex parte communication between any Party or its representative and any arbitrator regarding the arbitration proceeding or its subject matter.

(D)                               Preliminary Hearing. Within fifteen (15) Days after the arbitrators have been appointed, an initial meeting (preliminary hearing) among the arbitrators and counsel for the Parties shall be held for the purpose of developing a plan for the management of the arbitration, which shall then be memorialized in an appropriate stipulation and order. The matters which may be addressed by such plan and order include the following, among others: (i) definition of issues and, if appropriate, their division into preliminary and substantive or liability and damages issues; (ii) scope, timing, and types of discovery, if any; (iii) exchange of documents and filing of detailed statements of claim and defense and pre-hearing and other memoranda, either on all issues or on preliminary or liability issues in the first instance; (iv) whether and to what extent the direct testimony of witnesses (or categories of witnesses, such as experts) will be received by affidavit or written witness statement; (v) schedule and places of hearings; (vi) setting of other timetables; (vii) whether and to what extent expert testimony will be required, whether the arbitrators should engage one or more neutral experts, and whether, if this is done, engagement of experts by the Parties can be obviated or minimized; (viii) self-authentication of documents; and (ix) any other matters

3

which may promote the efficient, expeditious, and cost-effective conduct of the proceeding.

If the Parties cannot agree on the matters to be addressed in such a plan (including what evidentiary rules shall apply), such plan shall be developed by the arbitrators.

(E)                                 Discovery. The arbitrators shall permit and facilitate such discovery as it shall determine is appropriate under the circumstances, taking into account the needs of the Parties and the desirability of making discovery expeditious and cost-effective. Such discovery may include prehearing depositions, particularly depositions of witnesses who will not appear personally to testify, if there is a substantial, demonstrated need therefor. The arbitrators may issue orders to protect the confidentiality of proprietary information, trade secrets, and other sensitive information disclosed in discovery. Discovery shall be conducted and completed within the following time periods: (i) if the dispute involves an amount in controversy of $100,000 or less, within two (2) Months after the selection of the arbitrator has been completed; (ii) if the dispute involves an amount in controversy in excess of $100,000, but less than $500,000, within four (4) Months after the selection of the arbitrators has been completed; and (iii) if the dispute includes an amount in controversy of $500,000 or more, within nine (9) Months after the selection of the arbitrators has been completed.

(F)                                 Efficient Communications. Papers, documents, and written communications shall be served by the Parties directly upon each other and the arbitrators, with a simultaneous copy to the AAA tribunal administrator.

(G)                               Time Limits and Schedules. The proceedings shall be conducted in an expeditious manner, and a final award shall be rendered within the following time periods: (i) if the dispute involves an amount in controversy of $100,000 or less, within three (3) Months after the selection of the arbitrator has been completed, (ii) if the dispute involves an amount in controversy in excess of $100,000 but less than $500,000, within six (6) Months after the selection of the arbitrators has been completed, and (iii) if the dispute involves an amount in controversy of $500,000 or more, within one (1) year after the selection of the arbitrators has been completed. The arbitrators are empowered to impose time limits they consider reasonable for each phase of the proceeding including, without limitation, the time allotted to each Party for presentation of its case and for rebuttal.

(H)                               Conduct of Evidentiary Proceedings. The arbitrators shall actively manage the proceeding as they deem best so as to make the same fair, expeditious, economical, and less burdensome and adversarial than litigation. The arbitrators may, inter alia and without litigation, limit the issues so as to focus on the core of the dispute, limit the time allotted to each Party for presentation of its case, and

4

exclude testimony and other evidence that they deem irrelevant, cumulative, or inadmissible.

(I)                                    Self-Authentication of Documents. All documents that a Party proposes to offer in evidence, except for those objected to by an opposing Party, shall be self-authenticating.

(J)                                 Neutral Experts. Whenever expert testimony is required, the arbitrators may use their power to designate a neutral expert or experts in consultation with the Parties and shall explore with the Parties whether the retention of such neutral experts may render it unnecessary for each Party to proffer testimony by its own expert; provided, however, that each Party retains the right to proffer testimony by its own expert.

(K)                               Stenographic Transcripts. There shall be a stenographic transcript of the proceedings, the cost of which shall be borne equally by the Parties pending the final award. The arbitrators may require the Parties jointly to construct summaries of and indexes to testimony and to furnish copies to the arbitrators.

(L)                                Direct Testimony via Written Statements. The arbitrators may order that the direct testimony of all or of certain witnesses be furnished by a written, sworn statement. Any witness whose direct testimony is furnished by a written, sworn statement shall be subject to cross-examination in person.

(M)                        Governing Law; Limiting Arbitrators’ Equitable Discretion. The arbitrators shall determine the claims of the Parties and render their final award in accordance with Oklahoma Law as determined by the Agreement.

(N)                          Pre-Award Interest; Punitive Damages. The arbitrators may, in their discretion, grant pre-award interest and, if so, such interest shall be at commercial rates during the relevant period; provided, however, that under no circumstances shall the interest rate exceed the maximum legal rate as in effect during the relevant period. THE ARBITRATORS MAY NOT AWARD SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES UNDER ANY CIRCUMSTANCES AND WITHOUT REGARD TO FORUM OR JURISDICTION.

(O)                         Draft of Proposed Award. Prior to rendering their final award, the arbitrators shall submit to the Parties an unsigned, written draft of the proposed award, and each Party, within 15 days after receipt of such draft, may serve on the other Party and file with the arbitrators a written statement outlining any alleged errors of fact, computation, law, or otherwise in said draft. The arbitrators, in their discretion, may disregard and treat as a nullity any Party statement if and to the extent that the same is in substance an application for re-argument. Within 20 days after receipt of such Party statements, the arbitrators shall render their final award, which award shall be supported by a written decision.

5

4.             Confidentiality

The entire dispute resolution process is a compromise negotiation. All offers, promises, conduct, and statements, whether oral or written, made in the course of the proceeding by any of the Parties, their agents, employees, experts, and attorneys, and by the mediator or arbitrator are confidential. Such offers, promises, conduct, and statements are privileged under any applicable mediation or arbitration privilege, are subject to Rule 408 of the Federal Rules of Evidence and any state counterpart rules or doctrine and are inadmissible and not discoverable for any purpose, including impeachment, in litigation between the Parties to the mediation or other litigation; provided, however, that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its presentation or use at the mediation or arbitration. Any mediator will be disqualified as a witness, consultant, or expert for any Party, and as arbitrator between the Parties, and his or her oral and written opinions will be inadmissible for all purposes in this or any other dispute involving the Parties hereto.

5.             Performance to Continue

During the period that the Parties are engaged in mediation or arbitration, each Party is required to continue to perform its obligations under this Agreement, subject to the terms and conditions of any applicable court order to the contrary, pending final resolution of any dispute arising out of or relating to this Agreement, unless to do so would be impossible or impracticable under the circumstances.

Article II

Expedited ADR/Expert Determination

In the event of a disagreement between the Parties regarding payment of rental issues, or as otherwise specified in the Agreement, then either Party may submit a written request to the other Party requesting a meeting of the Parties’ respective representatives to attempt to resolve the dispute. Such representatives shall meet within three (3) Business Days thereafter at the receiving Party’s offices. If such meeting fails to resolve the dispute within seven (7) Days following the written request for meeting, either Party (the “Initiating Party”) may request in writing to the other that the disputed issue be referred to executives of the respective Parties who are at a higher level of management than the representatives and who have authority to settle the dispute (“Executive”). The Initiating Party shall include in its notice a summary of its position regarding the disputed issue, and the receiving Party shall serve a response thereto on the Initiating Party within five (5) Days thereafter. An Executive from each Party will meet at the receiving Party’s corporate or principal headquarter offices, or at such location as the Parties may mutually agree within seven (7) Days following mailing of the receiving Party’s response. If the Parties do not resolve the dispute within twenty-one (21) Days following the request for referral to Executives, then either Party may request that the dispute be referred to an expert. An expert is a person generally recognized as an expert in the field or fields of expertise relevant to the dispute. Except per specific agreement of both Parties, no

6

Person shall serve as an expert who has ever been previously employed in any capacity or hired as a consultant for either one of the Parties or any of their Affiliates. In the event that the Parties cannot agree on the expert within seven (7) Days after request for referral, then either Party may obtain designation of an expert by a nationally recognized professional society or organization in the discipline to which the dispute relates. Once designated, the expert will consult with both Parties and review all the relevant material submitted by each Party. Oral submission to the expert shall be made by representatives of both Parties in the presence of each other at a mutually satisfactory date and place or, in absence of agreement of the Parties, as specified by the expert, within thirty (30) Days following selection of the expert. The expert shall provide his or her written decision, together with reasons therefor, simultaneously to both Parties within fourteen (14) Days following the oral submission. The expert may, subject to prior written approval of the Parties, obtain independent or technical advice as he or she may deem necessary. The rules of arbitration either in general or as set forth in Article I shall not apply to this process. Each Party shall bear its respective costs, and the Parties shall share equally the cost of the expert and any independent advisers hired by the expert.

The decision of the expert made under this Article II shall be final and binding on both Parties and may be enforced in any court with competent jurisdiction.
