This Services Agreement (“Agreement”) is made and entered into as of the [    ]^th day of [            ], 2006 (the “Effective Date”) by and among ONEOK, Inc., an Oklahoma corporation (“ONEOK”), Northern Plains Natural Gas Company, LLC, a Delaware limited liability company (“Northern Plains”), NBP Services, LLC, a Delaware limited liability company (“NBP Services”), Northern Border Partners, L.P., a Delaware limited partnership (the “MLP”), and Northern Border Intermediate Limited Partnership (the “ILP”), a Delaware limited partnership. Each party is referred to herein individually as a “Party,” and collectively as the “Parties.” Capitalized terms used herein and not otherwise defined shall have the meanings given to them in Section 10.1.

W I T N E S S E T H:

WHEREAS, the MLP and ILP previously contracted for NBP Services to provide certain services to the MLP and the ILP in connection with the day-to-day business and affairs of the MLP and ILP pursuant to the Administrative Services Agreement;

WHEREAS, the Parties desire for the Administrative Services Agreement to be terminated, superseded and replaced by this Agreement and to have the services previously provided under that Administrative Services Agreement be provided under this Agreement;

WHEREAS, Northern Plains, pursuant to certain Operating Agreements, is the operator of certain interstate natural gas pipelines in which the MLP and the ILP have an ownership interest;

WHEREAS, the Operating Agreements each provide that Northern Plains may delegate or cause one or more of its affiliates to fulfill its obligations under the Operating Agreements;

WHEREAS, certain affiliates of ONEOK own all of the outstanding general partner interests of each of the MLP and ILP and own a substantial percentage of the outstanding equity interests in the MLP;

WHEREAS, the Parties have determined that the operations of ONEOK and its affiliates and the Northern Border Companies can operate more efficiently and cost effectively if certain common services are combined and shared;

WHEREAS, certain ONEOK Affiliates and Northern Border Companies are regulated by various governmental entities that require a fair and reasonable method of allocation for costs incurred for such common services; and

WHEREAS, ONEOK (an affiliate of NBP Services and Northern Plains) desires to provide or cause the provision of certain services to the Northern Border Companies, and the Northern Border Companies desire to receive these services, in accordance with the terms and conditions of this Agreement.

NOW THEREFORE, in consideration of the premises and the agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are

hereby acknowledged, and intending to be legally bound hereby, the Parties hereby agree as follows:

ARTICLE I

SERVICES TO BE PROVIDED

1.1 Services. On the terms and conditions set forth in this Agreement, ONEOK will provide or cause to be provided to the Northern Border Companies at least the type and amount of services that it provides or causes to be provided to ONEOK Affiliates, including but not limited to, executive officers, legal services, human resources and employee benefits, information technology, insurance and risk management, purchasing, inventory control, gas supply services, marketing, pipeline control, right of way management, general operations and maintenance, measurement, engineering, accounting, contract administration, SEC reporting, day-to-day supervisory and administrative services, planning support, budgeting support, technical, treasury services, tax and internal audit services, external audit services and other services required to be provided pursuant to the partnership agreements of the MLP and ILP, as amended from time to time, and various other services routinely and customarily provided to the ONEOK Affiliates (the “Services”). Each Northern Border Company or permitted successor or assign that receives Services shall be referred to as a “Purchaser” and collectively as the “Purchasers”. ONEOK and the ONEOK Affiliates that provide Services under this Agreement, including Northern Plains and NBP Services, shall be collectively referred to as the “Provider.”

1.2 Operating Agreement Services. The Parties acknowledge and agree that Northern Plains will continue to perform its obligations under each of the Operating Agreements. To the extent Northern Plains requests Services from ONEOK under this Agreement in order to perform those obligations, ONEOK shall provide such Services, and Northern Plains shall pay for such Services, under the terms and conditions set forth in this Agreement. To the extent Northern Plains receives Services under this Agreement, it will be deemed a “Purchaser” with respect to such Services.

1.3 Additional Services. Any additional services requested by any Purchaser will be provided on the basis agreed upon by the Parties in writing. Unless the context otherwise requires, the term “Services” in this Agreement shall include any such additional services agreed upon in writing by the Parties.

1.4 Costs. The costs for the Services provided under this Agreement will be allocated and billed monthly to the Purchasers in a manner consistent with the method of allocation of such costs among other ONEOK Affiliates and consistent with applicable law, including the requirements of the Federal Energy Regulatory Commission (“FERC”). Direct costs will be allocated to the Purchasers having activities that give rise to such costs to the extent that such direct basis can reasonably be determined and allocated. The remaining unallocated direct costs and all indirect costs will then be allocated on the basis of a three-factor formula (the “Distrigas Method”), consistent with methods approved by the FERC. The Distrigas Method provides for the allocation of common costs based on the average of the percentage of “gross plant and investment”, “operating income” and “labor expense,” as such terms are defined in FERC regulations of each company involved in the calculation. The Provider will determine an average of those three factors for each Purchaser and for ONEOK and each ONEOK Affiliate

2

that is involved in the calculation. That average will be the allocation ratio for each such entity (the “Distrigas Allocation Ratio”). The Distrigas Allocation Ratio for each such entity will then be applied to the total amount of common costs to determine the amount of common costs that will be allocated to each such entity. The Distrigas Allocation Ratio will be recalculated annually, or as required due to acquisitions, divestitures or other similar types of transactions or regulatory requirements. For the avoidance of doubt, the costs allocated through the Distrigas Method are based on actual costs recognized under U.S. generally accepted accounting principles and do not include a mark-up or other element of profit. The Provider is not entitled to and will not receive any other fee or other compensation for the performance of the Services other than as set forth in this Section 1.4.

ARTICLE II

SERVICE STANDARD

2.1 Standard of Care; Limited Warranty.

(a) The Provider represents that it will discharge its duties hereunder in good faith and with reasonable diligence and on a basis consistent with the standards of service provided to ONEOK Affiliates. EXCEPT AS SET FORTH IN THE IMMEDIATELY PRECEDING SENTENCE, THE PROVIDER MAKES NO (AND HEREBY DISCLAIMS AND NEGATES ANY AND ALL) WARRANTIES OR REPRESENTATIONS WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO THE SERVICES. IN NO EVENT SHALL THE PROVIDER BE LIABLE TO THE NORTHERN BORDER COMPANIES OR ANY OTHER PERSON FOR ANY INCIDENTAL, CONSEQUENTIAL, OR SPECIAL DAMAGES RESULTING FROM ANY ERROR IN THE PERFORMANCE OF THE SERVICES, REGARDLESS OF WHETHER THE PROVIDER OR OTHERS MAY BE WHOLLY, CONCURRENTLY, PARTIALLY, OR SOLELY NEGLIGENT OR OTHERWISE AT FAULT; PROVIDED HOWEVER, THAT THE PROVIDER SHALL BE LIABLE FOR ANY DAMAGES ARISING OUT OF ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. THE PRECEDING IS THE ONLY WARRANTY CONCERNING THE SERVICES AND ANY RESULTS, WORK PRODUCT OR PRODUCTS RELATED THERETO, AND IS MADE EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES AND REPRESENTATIONS EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, THE WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE, MERCHANTABILITY OR NONINFRINGEMENT. THE PARTIES UNDERSTAND, ACKNOWLEDGE AND AGREE THAT THE LEVEL OF COMPENSATION THE PARTIES HAVE AGREED TO ACCEPT IS PREDICATED ON THIS LIMITATION OF LIABILITY AND DISCLAIMER OF WARRANTIES.

(b) The Parties shall agree and communicate regarding (i) any changes to the Services or (ii) service level expectations related to the Services. The Provider shall not make any changes to the Services or the manner in which they are provided without advance notice to the Purchaser.

2.2 Consequences of Breach or Non-Performance. The Purchasers shall promptly notify the Provider of any failure by the Provider to perform one or more of the Services in

3

accordance with the terms of this Agreement. In the event that the Provider does not cure such non-performance within thirty (30) business days of the receipt of such notice, the Purchasers may terminate such Service(s) by delivering notice to the Provider.

2.3 Relationship of Parties. The Parties hereby acknowledge and agree that, in providing the Services and otherwise in connection with this Agreement, the Provider is an independent contractor and is not, and shall not be deemed to be, an agent, employee or legal representative of the Purchasers or otherwise as having power or authority to bind the Purchasers, unless specifically delegated to do so in order to facilitate the Services.

ARTICLE III

TERM AND TERMINATION

3.1 Term. This Agreement shall become effective as of the Effective Date and shall remain in effect until terminated as herein provided or until Services are no longer being provided (the “Term”).

3.2 Termination of this Agreement. Except as set forth in Section 2.2 of this Agreement, a Party may not terminate this Agreement during the Term except under the following circumstances:

(a) The Parties may terminate this Agreement by the execution of a written agreement signed by authorized representatives of all Parties, in which event the termination shall be effective on the date specified in such agreement.

(b) If a transaction is consummated which would cause the Provider or its Affiliates (other than the Northern Border Companies and their subsidiaries) to cease to be a general partner of the MLP or the ILP, then ONEOK or the MLP, as the case may be, shall have the right to terminate this Agreement upon the execution and delivery of a mutually agreeable transition services agreement between the Parties.

3.3 Termination of the Administrative Services Agreement. Effective as of the execution and delivery of this Agreement, the Administrative Services Agreement is hereby terminated, superseded and replaced by this Agreement; provided, however, that all amounts due or to become due under that Administrative Services Agreement shall be paid in full and the Administrative Services Agreement shall continue in effect with respect thereto until all such amounts are paid in full.

ARTICLE IV

BILLING AND PAYMENT

4.1 Invoices. The Provider will send one monthly invoice to the ILP covering all of the Services provided under this Agreement. The monthly invoice will be sent following completion of the Provider’s normal monthly financial reporting process, including completion of the Distrigas Method calculation. The ILP shall pay each invoice by wire transfer or other means of immediate payment within fifteen (15) days of the invoice date without setoff or deduction of any kind, except as provided in Section 4.2. Any late payment by the ILP shall incur a late fee of ten percent (10%) per annum, calculated from the due date until the date of

4

payment. In the event that any invoice is based on estimated costs, the Provider shall make adjustments by increasing or decreasing the costs in the invoice subsequent to the determination of the actual costs.

4.2 Disputed Amounts. In the event that a dispute arises as to the amount of any statement or invoice or any portions thereof submitted pursuant to this Article IV, the Parties will resolve the dispute in accordance with this Section 4.2 and Section 4.3 below. Pending resolution of the dispute, the ILP may withhold payment of the amounts on an invoice or statement to the extent such amounts are disputed in good faith, but shall pay all charges on such invoice or statement that are not so disputed. If the ILP disputes any amount on an invoice or statement it shall promptly notify the Provider in writing of such disputed amounts and the reasons each such charge is disputed. The Provider shall provide the ILP with sufficient records relating to the disputed charge to enable the Parties to resolve the dispute. In the event the determination is made that the ILP should have paid the disputed amount, the ILP shall pay the disputed amount, with interest on the disputed amount at a rate of ten percent (10%) per annum, calculated from and after the original due date of such invoice until the date of payment. If the ILP paid the disputed amount, but such disputed amount is ultimately determined not to have been payable, then the Provider shall refund to the ILP the disputed amount, with interest on the disputed amount at a rate of ten percent (10%) per annum, calculated from and after the date the Provider received the payment to the date of the refund. Payment by the ILP of a disputed amount shall not be deemed a waiver of the right of the ILP to recoup any contested portion of any bill or statement.

4.3 Dispute Resolution. In the event of a dispute under this Agreement, the Parties shall, during the fifteen (15) days after notice of such a dispute, use their commercially reasonable efforts to reach agreement on the disputed items or amounts. If the Parties are unable to reach agreement within such period, they shall promptly thereafter cause a nationally recognized accounting firm agreeable to the Parties (the “Accounting Referee”) to review this Agreement and the disputed items or amounts. The Accounting Referee shall deliver to the Parties as promptly as practicable (but in any event no later than thirty (30) days from the date of engagement of the Accounting Referee), a report setting forth the Accounting Referee’s determination of the appropriate resolution of the dispute. Such determination shall be final and binding upon the Parties. The cost of such review and report shall be borne equally by each Party involved in the dispute.

4.4 Audit. The Northern Border Companies and their designated representatives, after fifteen (15) days notice in writing to the Provider, shall have the right during normal business hours to audit, at their own expense, all books and records of the Provider related to the Services. Such audits shall not be commenced more often than twice each calendar year. The Northern Border Companies shall have two (2) years after the close of a calendar year in which to make an audit of the Provider’s records for such calendar year. Absent fraud or intentional concealment or misrepresentation by the Provider or its employees, the Provider 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 bills and statements rendered shall be conclusively established as correct. The Provider shall use reasonable

5

commercial efforts to obtain similar audit rights from contractors, consultants and suppliers engaged to perform any of the Services on behalf of the Provider.

ARTICLE V

LIMITATION OF LIABILITY AND INDEMNITIES

5.1 Purchaser’s Limitation of Liability. Each of the Northern Border Companies agrees, with respect to the Services provided to such entity hereunder, to indemnify, defend and hold harmless the Provider and its Affiliates (provided that Northern Plains shall not be entitled to indemnity for any costs, expenses or liabilities incurred by it as a general partner of the MLP or the ILP), and their respective employees, officers, directors, representatives and agents harmless from and against all claims, losses, costs, damages and expenses (including, without limitation, attorneys’ fees and expenses), penalties and liabilities (collectively, “Liabilities”) arising out of the acts (or failure to act) by any such persons or entities in connection with the performance by such persons or entities of such Services, REGARDLESS OF WHETHER THE PROVIDER, OR SUCH OTHER PERSONS OR ENTITIES MAY BE WHOLLY, CONCURRENTLY, PARTIALLY OR SOLELY NEGLIGENT OR OTHERWISE AT FAULT IN CONNECTION THEREWITH; PROVIDED, HOWEVER, THAT NEITHER THE PROVIDER NOR ANY OF SUCH OTHER PERSONS AND ENTITIES SHALL BE INDEMNIFIED FOR THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PROVIDER OR SUCH OTHER PERSONS OR ENTITIES.

5.2 Provider’s Indemnification. The Provider shall indemnify, defend and hold the Northern Border Companies and their general partners and their respective employees, directors, policy committee members, officers, representatives and agents harmless from and against all Liabilities arising out of the performance of this Agreement and resulting from the gross negligence or willful misconduct of the Provider or its Affiliates.

5.3 Defense of Claims. It is understood and agreed that in the event that any Party is made a defendant in any suit, action or proceeding for which it is entitled to be indemnified pursuant to this Agreement, and the applicable indemnifying party fails or refuses to timely assume the defense thereof, after having been notified by the indemnified party to do so, that the indemnified party may compromise and settle or defend any such claim, and the applicable indemnifying party shall be bound and obligated to reimburse said indemnified party for the amount expended by the indemnified party in settling and compromising any such claim, or for the amount expended by the indemnified party in paying any judgment rendered therein, together with all reasonable attorneys’ fees and costs incurred by the indemnified party for defense or settlement of such claim. Any judgment rendered against the indemnified party or amount expended by the indemnified party in compromising or settling such claim, together with all reasonable attorneys’ fees and costs, shall be conclusive as determining the amount for which the applicable indemnifying party is liable to reimburse the indemnified party hereunder.

ARTICLE VI

CONFIDENTIALITY AND OWNERSHIP OF RECORDS

6.1 Confidentiality. The Parties acknowledge that in the course of this Agreement they may have access to and be in possession of Confidential Information (as described

6

immediately below) of the other Party. Each Party shall protect the other Parties’ Confidential Information in the same manner as it protects its own confidential information of like kind, which in no event shall be less than reasonable care. Each Party’s access to the Confidential Information of the other Parties shall be restricted to those of such Party’s personnel who have a need to know in order to perform under this Agreement. The provisions of this Section shall survive any termination or expiration of this Agreement and shall not be limited by any limitation of liability contained herein.

6.2 Ownership of Records. The Northern Border Companies shall own the data, records, information, etc. provided, generated, or otherwise related to the Services and the business of the Northern Border Companies (“Northern Border Company Records”), regardless of who prepares or generates such Northern Border Company Records. The Provider shall maintain on behalf of the Northern Border Companies all Northern Border Company Records and shall not destroy or delete any Northern Border Company Records without the prior written consent of the Northern Border Companies. Additionally, should this Agreement be terminated, then the Provider shall deliver or cause to be delivered all Northern Border Company Records to the Northern Border Companies; provided, however, that ONEOK shall be entitled to retain copies of any such Records.

7.1 Force Majeure. Subject to the standards set forth in Article II, if, by reason of force majeure (as defined in Section 7.2 below), a Party is rendered unable, wholly or in part, to carry out its obligations under this Agreement, and if the non-performing Party declaring force majeure gives notice and reasonable particulars of such force majeure to the Party to whom the performance is due within a reasonable time after the occurrence of the cause relied on, upon giving such notice, so far as and to the extent that it is affected by such force majeure, the non-performing Party declaring force majeure shall not be liable solely on account of such inability to perform during the continuance of any inability so caused; provided, however, the non-performing Party shall use commercially reasonable efforts to recommence performance of the affected Services as promptly as possible; provided, further, however, that an event of force majeure shall not excuse payment for Services provided hereunder.
