5.2. Budgets. Each December, the Operator shall submit for approval of the Management Committee operating and capital budgets which the Operator anticipates for the ensuing

Year, including such supporting documentation and data as the Management Committee may require. Except as the Management Committee may otherwise direct, the budgets approved by the Partnership and then in effect shall constitute authorization of the Operator to incur the expenditures contained in any such budget and to incur expenditures of up to one million dollars in excess of the amount set forth in any such budget.

5.3. Disputed Charges. The Partnership may, within the time provided in the Accounting Procedure, take written exception to any xxxx or statement rendered by the Operator for any expenditure or any part thereof, on the ground that the same was not a reasonable, authorized, and proper cost incurred by the Operator in connection with the design, construction, operation, maintenance, or administration of the Facilities or its

other duties and responsibilities as Operator hereunder. The Partnership shall nevertheless pay in full when due the amount of all statements submitted by the Operator. Such payment shall not be deemed a waiver of the right of the Partnership to recoup any contested portion of any xxxx or statement. However, if the amount as to which such written exception is taken or any part thereof is ultimately determined not to be a reasonable, authorized, and proper expense incurred by the Operator hereunder, such amount or portion thereof (as the case may be) shall be refunded by the Operator to the Partnership together with interest thereon at a rate (which in no event shall be higher than the maximum rate permitted by applicable law) equal to the rate designated by Citibank, N.A. from time to time as its prime rate during the period from the date of payment by the Partnership to the date of refund by the Operator.

5.4. Audit and Examination. Any Partner(s), the Partnership or their designated representatives (including in the case of the Partnership representatives from each Partner), after fifteen (15) Days’ notice in writing to the Operator, shall have the right during normal business hours to audit or examine, at the expense of the Person (Partner(s) or Partnership) conducting the audit or examination, all books and records of the Operator as well as the relevant books of account of the Operator’s contractors relating to the design, construction, operation, maintenance, and repair of the Facilities and the administrative services provided under this Agreement; provided, however, that the total number of full audits commenced in any Year shall not exceed one. Such right shall include the right to meet with the Operator’s internal and independent auditors to discuss matters relevant to the audit or examination. The Partnership shall have two (2) Years after the close of a Year in which to make an audit of the Operator’s records

for such Year; provided, however, that any audits relating to construction costs may be made up to twenty-four (24) Months after the date of completion. Absent fraud or intentional concealment or misrepresentation by the Operator or its employees, and except for any adjustments which may arise from FERC compliance audits, the Operator shall neither be required nor permitted to adjust any item unless a claim therefor is presented or adjustment is initiated within two (2) Years after the close of the Year in which the statement therefor is rendered, and in the absence of such timely claims or adjustments, the bills and statements rendered shall be conclusively established as correct; provided, however, this shall not prevent adjustment resulting from physical inventory of the Facilities and other Partnership property or audit adjustments relating to construction costs incurred as set forth in this Section 5.4.

6. Agent.

6.1. Agent. In performing services pursuant to this Agreement, the Operator shall be an agent of the Partnership.

Any: (i) inventions, whether patentable or not, developed or invented, or (ii) copyrightable material developed by the Operator or its employees while engaged exclusively in the performance of services under this Agreement shall, unless otherwise directed, be assigned to the Partnership, which shall have the exclusive right to the exploitation thereof.

7.2. Confidentiality. Because the information and knowledge gained during the performance of services under this Agreement may consist of valuable proprietary information, the misuse or disclosure of which could cause substantial damage to the Partnership, any and all information obtained by the Operator in performance of its obligations under this

Agreement shall be held in strict confidence by the Operator, its employees or agents except as needed to comply with the purposes of this Agreement. Where appropriate, any contracts entered into by the Operator related to its obligations under this Agreement shall contain a provision which similarly restricts the use and disclosure of such information.

8. Indemnification, Litigation, Insurance and Liability.

8.1. Partnership’s Indemnity.

8.1.1. The Partnership shall indemnify and save harmless the Operator and its directors, officers, agents and employees against all litigation, actions, claims, demands, debts and liabilities, and any costs including without limitation reasonable legal fees and expenses incurred in connection therewith, (to the extent only that such litigation, actions, claims, demands, debts and liabilities are

not satisfied by insurance carried pursuant to Section 8.2.1 below) arising out of the acts (or failure to act) of the Operator, its directors, officers, agents and employees in good faith and reasonably believed by the Operator, its directors, officers, agents and employees to be within the scope of the Operator’s authority under this Agreement, including actions, claims, demands, costs and liabilities resulting from the negligence (but not the gross negligence or willful misconduct) of the Operator, its directors, officers, agents and employees, and the Operator, its directors, officers, agents, and employees shall not be liable for any obligations, liabilities, or commitments incurred by or on behalf of the Partnership as a result of any such acts (or failure to act).

8.1.2. Any and all claims, damages or causes of action against the Partnership in favor of anyone other than the Operator arising out of the design, construction, operation, maintenance, and repair of the Facilities and the administrative services provided under this Agreement that are not covered by insurance as per Section 8.2 of this Agreement shall be settled or litigated and defended by the operator in accordance with its best judgment and discretion when (i) the amount involved is less than a ceiling amount to be established by the Management Committee; (ii) no injunctive or similar relief is sought; and (iii) no criminal sanction is sought; otherwise, such decision shall be made by the Management Committee, and any settlement or defense

thereof shall be controlled by the Management Committee.

8.2. Insurance.

8.2.1. The operator shall carry and maintain, as approved by the Management Committee, insurance which it reasonably deems adequate to protect the Operator, its directors, officers, agents and employees against all actions, claims, demands, costs and liabilities arising out of the negligence of the operator, its directors, officers, agents and employees in connection with the duties and responsibilities of the operator hereunder. The Operator shall, subject to the approval of the Management Committee, carry and maintain such other insurance for the benefit of the Partnership and the Operator and require contractors, subcontractors or consultants to carry and

to maintain insurance, as directed by the management Committee, (i) to protect the Partnership and the Operator and (ii) to satisfy any other requirement of the law.

8.2.2. Insurance maintained by the Operator pursuant to Section 8.2.1 of this Agreement shall be a reimbursable cost pursuant to Section 5 of this Agreement.

8.2.3. The Operator may carry and maintain such other insurance for its own account as it may deem necessary.

8.2.4. With respect to claims and losses for damage, injury or destruction of property that is a part of the Facilities, which property is covered by insurance other than insurance provided for in Section 8.2.1 of this Agreement, it is

agreed that neither the Operator nor the Partnership or any of its Partners shall have any rights of recovery against one another, nor against Affiliates of either, nor the insurers of any of them, and their rights of recovery are mutually waived. All such policies of insurance purchased to cover the Facilities or any part thereof, or the operation (in any respect) of the Facilities or any part thereof, or any gas transported or handled therein, shall be endorsed properly to effectuate this waiver of recovery; provided, however, that if the Partnership, any of the Partners, or the Operator is unable, despite its best efforts, to obtain such an endorsement, then the other Parties may waive or appropriately modify this requirement.

8.3. Limitation of Liability. Any claim of the Operator against the Partnership which may arise hereunder shall be made only against the assets of the Partnership, and all rights to proceed against the Partners and the assets of the Partners, other than their interests in the Partnership, as a result of any such claim or any obligation arising therefrom, are hereby expressly waived. The operator shall endeavor to include a similar provision in all contracts entered into by the Operator pursuant to this Agreement.

9. Term.

12.1. Effect of Force Majeure. In the event that either the Partnership or the operator is rendered unable, by reason of an event of force majeure, as defined herein, to perform, wholly or in part, any obligation or commitment set forth in this Agreement, then

ACCOUNTING PROCEDURE

ARTICLE I

General Provisions

1.01 Statements and Xxxxxxxx. The Operator shall xxxx the Partnership on the first day of each month or as soon as possible thereafter for the estimated costs and expenses for the month and any adjustment which may be necessary to correct prior estimated xxxxxxxx to actual. Such bills will be summarized by appropriate classifications indicative of the nature thereof.

1.02 Payment by Partnership. The Partnership shall pay all bills presented as provided in the Operating Agreement on or before the 15th day after the billing date. If payment is not made within such time, the unpaid balance shall bear interest until paid at a rate (which in no event shall be higher than the maximum rate or rates permitted by applicable law) equal to the rate designated by Citibank, N.A. from time to time as its prime rate; provided, however, that if employees of the Operator are responsible for writing the

Partnership’s checks and the Partnership has sufficient funds to make payment, no interest charge shall be imposed for late payment. Payment by or on behalf of the Partnership shall not be deemed a waiver of the right to recoup any amount in question.

1.03 Adjustments. Payment of any bills shall not prejudice the right of the Partnership to protest or question the correctness thereof; provided, however, that, absent fraud or intentional concealment or misrepresentation by the Operator or its employees, all bills and statements rendered to the Partnership by the operator during any calendar year shall conclusively be presumed to be true and correct after 24 months following the end of any such calendar year, unless prior to the end of said 24-month period the Partnership takes written exception thereto and makes claim on the Operator for adjustment; provided, however, this shall not prevent adjustment resulting from FERC Compliance Audits or the physical inventory of the Facilities and other Partnership property, and any adjustments relating to construction costs may be made up to 24 months after the date of completion. No adjustment favorable to the

Operator shall be made unless it is made within the same prescribed period.

1.04 Financial Records. The Operator shall maintain accurate books and records in accordance with the Required Accounting Practice covering all of the Operator’s actions under this Operating Agreement.

ARTICLE II

Capital Items

Except for items included in a previously approved budget, prior to the acquisition of any property, real or personal, costing more than a ceiling amount to be established by the Management Committee in the name or on behalf of the Partnership which under the accounting rules and regulations, if any, at the time prescribed by the regulatory body or bodies under the jurisdiction of which the Partnership is at the time operating, might be capitalized, the operator shall prepare and submit to the Partnership a forecast of the cost of all such property. Upon approval of such forecast by the Partnership (including approval of the proposed purchase), the Operator shall have authority to purchase such property in the Partnership’s name without further approval or action by the Partnership. To the extent the Operator owns property necessary or desirable

for the operation and maintenance of the Facilities that: (i) under the accounting rules and regulations, if any, prescribed by the regulatory body or bodies under the jurisdiction of which the Partnership is at the time operating, might be capitalized, (ii) the Operator in its sole discretion is willing to transfer for consideration to the Partnership, and (iii) can be transferred by the Operator to the Partnership free and clear of all prior liens and encumbrances, the Operator, if approved by the management Committee, may so transfer such property to the Partnership and charge the Partnership the net book value thereof as reflected on the books of the Operator on the date of transfer.

ARTICLE III
