The ILP may, within the time period provided in Section 3.5, take written exception to any statement, or any part thereof, rendered by NPNG for any amount set forth therein pursuant to Sections 3.2(a) or 3.2(b), on the grounds that the same was not a reasonable, authorized, and proper cost incurred by NPNG in discharging its responsibilities and obligations pursuant to the Operating Agreement and the Interim and Conversion Services Agreement or was not the correct amount of compensation to be received by NPNG from Guardian Pipeline, L.L.C. pursuant to the Operating Agreement and the Interim and Conversion Services Agreement. The ILP shall nevertheless pay all amounts calculated pursuant to Section 3.3(a) in full when due. If, however, the amount as to which such written exception is taken or any part thereof is ultimately determined by the ILP not to be a reasonable, authorized, and proper cost, expense or expenditure incurred by NPNG in discharging its responsibilities and obligations under the Operating Agreement and the Interim and Conversion Services Agreement or the correct amount of compensation to be received by NPNG from Guardian Pipeline, L.L.C. pursuant to the Operating Agreement and the Interim and Conversion Services Agreement, such amount or portion thereof (as the case may be) shall be refunded by NPNG to the ILP together with interest thereon at a rate (which in no event shall be higher than the maximum rate or rates permitted by applicable law) equal to the prime rate charged by Citibank, N.A. in New York, New York from time to time to responsible commercial and industrial borrowers during the period from the date of payment by the ILP to the date of refund by NPNG.

The ILP shall have two (2) years after the close of a calendar year in which to make an audit of NPNG's records for such calendar year. Absent fraud or intentional concealment or misrepresentation by NPNG or its employees, NPNG shall neither be required nor permitted to adjust any item unless a claim therefore is presented or adjustment is initiated within two (2) years after the close of the calendar year in which the statement therefore is rendered, and in the absence of such timely claims or adjustments, the statements rendered shall be conclusively established as correct. NPNG shall obtain similar rights from contractors, consultants and suppliers engaged to discharge any of the responsibilities and obligations under the Operating Agreement and the Interim and Conversion Services Agreement.

Despite the filing of any such injunctive or other provisional judicial relief, the Parties shall continue, subject to Section 4.5 below, to participate in the applicable procedures specified in this Article IV. 4.2 INITIATION OF PROCEDURES. A Party desiring to initiate the dispute resolution procedures set forth in this Article IV with respect to a Dispute not resolved in the ordinary course of business (the "Initiating Party") shall give written notice of the Dispute (the "Dispute Notice") to the other Party (the "Non-Initiating Party"). The Dispute Notice shall include (i) a statement of that Party's position and a summary of arguments supporting that position, and (ii) the name and title of the executive who will represent that Party, and of any other person who will accompany the executive, in the negotiations under Section 4.3 below. 4.3 NEGOTIATION BETWEEN EXECUTIVES.

Within fifteen (15) days after receipt of the Dispute Notice, the Non-Initiating Party shall submit to the other a written response. Such response shall include (i) a statement of that Party's position and a summary of arguments supporting that position, and (ii) the name and title of the executive who will represent that Party and of any other person who will accompany the executive.

(a) If the Dispute has not been resolved within the required time period, or if the failure and/or refusal of a Party to participate in such procedures makes such procedures futile, either Party may initiate arbitration to resolve the Dispute by submitting a written notice of same to the other Party ("Arbitration Notice"). Any arbitration hereunder shall be conducted under the auspices of the American Arbitration Association (the "AAA") and its rules (the "Rules"), except to the extent terms expressly set forth in this Article IV are in conflict with or supplement such Rules, and shall be governed by the Federal Arbitration Act, 9 U.S.C.

(b) The arbitral panel shall consist of an odd number of arbitrators selected in the following manner. The Arbitration Notice shall name the noticing Party's arbitrator and shall contain a statement of the Dispute(s) presented for arbitration. Within fifteen (15) days of receipt of an Arbitration Notice, the other Party shall name its arbitrator by written notice to the noticing Party and may designate any additional Dispute(s) for arbitration. The Party-selected arbitrators shall select an additional, neutral arbitrator within fifteen (15) days after the date on which the final Party-selected arbitrator was named. Should the Party-selected arbitrators fail to agree on the selection of the neutral arbitrator, the noticing Party shall be entitled to request AAA to select the neutral arbitrator(s). Should the other Party fail and/or refuse to name its arbitrator within the required fifteen (15) day period, the other Party shall be entitled to request AAA to select the arbitrator for such Member. All arbitrators shall be qualified by education or experience within the natural gas interstate transportation portion of the energy industry to decide the Disputes presented for arbitration.

(c) Arbitration Hearing. The arbitrators shall commence the arbitration proceedings within twenty-five (25) days following the appointment of the final neutral arbitrator. The arbitration proceedings shall be held at a mutually acceptable site and if the Parties are unable to agree on a site, the arbitrators shall select the site. The arbitrators shall have the authority to establish rules and procedures governing the arbitration proceedings, including, without limitation, rules concerning discovery. Each Party shall have the opportunity to present its evidence at the hearing. The arbitrators may call for the submission of pre-hearing statements of position and legal authority, but no post-hearing briefs shall be submitted. The arbitral panel shall not have the authority to award incidental, consequential, special, punitive or exemplary damages. All evidence submitted in the arbitration proceedings, transcripts of the proceedings, and all documents submitted by the Parties in the proceedings shall be kept confidential and shall not be disclosed to any third party by any Party. (d) Arbitration Decision and Costs. The decision of the arbitrators, or a majority of them, shall be in writing, shall explain the rationale of their decision, and shall be final and binding upon the Parties as to the Dispute(s) submitted for resolution. The cost of the arbitration hearing shall be shared equally by the Parties. Each Party hereby irrevocably waives, to the fullest extent permitted by law, any objection it may have to the arbitrability of any such disputes, controversies or claims and further agrees that a final determination in any such arbitration proceedings shall be final, conclusive, nonappealable and binding upon each Member.
