Our Natural Gas Gathering and Processing segment sells natural gas to  ONEOK and its subsidiaries. A portion of our Natural Gas Pipelines segment&amp;#8217;s  revenues are from ONEOK and its subsidiaries. Additionally, our Natural Gas  Gathering and Processing segment and Natural Gas Liquids segment purchase a  portion of the natural gas used in their operations from ONEOK and its  subsidiaries.&lt;/font&gt;&lt;/div&gt;       &lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&amp;#160;&lt;/div&gt;       &lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;We have  certain contractual rights to the Bushton Plant. Our Processing and Services  Agreement with ONEOK and OBPI sets out the terms by which OBPI provides services  to us at the Bushton Plant through 2012. We have contracted for all of the  capacity of the Bushton Plant from OBPI. In exchange, we pay OBPI for all costs  and expenses necessary for the operation and maintenance of the Bushton Plant,  and we reimburse ONEOK for a portion of OBPI&amp;#8217;s obligations under equipment  leases covering the Bushton Plant.&lt;/font&gt;&lt;/div&gt;       &lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&amp;#160;&lt;/div&gt;       &lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Under the  Services Agreement with ONEOK, ONEOK Partners GP and NBP Services (Services  Agreement), our operations and the operations of ONEOK and its affiliates can  combine or share certain common services in order to operate more efficiently  and cost effectively. Under the Services Agreement, ONEOK provides to us similar  services that it provides to its affiliates, including those services required  to be provided pursuant to our Partnership Agreement. ONEOK Partners GP may  purchase services from ONEOK and its affiliates pursuant to the terms of the  Services Agreement. ONEOK Partners GP has no employees and utilizes the services  of ONEOK and ONEOK Services Company to fulfill its operating  obligations.&lt;/font&gt;&lt;/div&gt;       &lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&amp;#160;&lt;/div&gt;       &lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;ONEOK and  its affiliates provide a variety of services to us under the Services Agreement,  including cash management and financial services, employee benefits provided  through ONEOK's benefit plans, administrative services, insurance and office  space leased in ONEOK's headquarters building and other field locations. Where  costs are specifically incurred on behalf of one of our affiliates, the costs  are billed directly to us by ONEOK. In other situations, the costs may be  allocated to us through a variety of methods, depending upon the nature of the  expense and activities. For example, a service that applies equally to all  employees is allocated based upon the number of employees. However, an expense  benefiting the consolidated company but having no direct basis for allocation is  allocated by the modified Distrigas method, a method using a combination of  ratios that include gross plant and investment, earnings before interest and  taxes and payroll expense. It is not practicable to determine what these general  overhead costs would be on a stand-alone basis. All costs directly charged or  allocated to us are included in our Consolidated Statements of  Income.&lt;/font&gt;&lt;/div&gt;       &lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&amp;#160;&lt;/div&gt;
