| 1. | Crude Oil shall be measured by LACT/ACT Units installed, maintained and operated by Gatherer or its designee, in the case of Crude Oil gathered via the Gathering System, or from static tank gauges on 100% tank table basis (or by use of mutually acceptable automatic measuring equipment), in the case of Crude Oil trucked by Gatherer, and computations made in accordance with accepted API and industry practices.  Such LACT/ACT Units shall be operated within appropriate flow rate, temperature and pressure ranges for existing operating conditions.  Volume computations shall be made as accurately as possible and within the accuracy prescribed by the manufacturer of the recording and computing equipment used utilizing accepted API and industry practices and procedures. |

| 3. | Temperature shall be determined by a dynamic electronic temperature averaging device.  The API Gravity, sulfur content and suspended sediment and water content of the Crude Oil shall be determined by measurement of the oil samples collected from the LACT/ACT Units and pipeline sample pots, in the case of Crude Oil gathered via the Gathering System, or from static tank gauges on 100% tank table basis (or by use of mutually acceptable automatic measuring equipment), in the case of Crude Oil trucked by Gatherer.  Analysis of the accumulated samples shall be made at operational times agreed upon by both the Shipper and the Gatherer no less than once per Month. |

| 5. | The accuracy of Gatherer's measuring equipment shall be verified by Gatherer or its designee every three (3) Months.  Upon request by Shipper, notice of the date and time of the testing of such equipment or for the quality of the Crude Oil shall be given by Gatherer to Shipper sufficiently in advance to permit convenient arrangement for Shipper's representative to be present.  If after proper notice, Shipper fails to have a representative present, the results of the test shall nevertheless be considered accurate.  All tests shall be made at Gatherer's expense, except that Shipper shall bear the expense of tests made at its request if the meter factor is determined to deviate, plus or minus, five one-hundredths of one percent (0.05%) or less from the meter factor previously determined. |

| 6. | If at any time the measuring or testing equipment is found to be out of service or registering inaccurately in any percentage, it shall be adjusted at once to read accurately within the limits prescribed by the manufacturer.  If such conditions exist, then corrections shall be made for any period which is definitely known or agreed upon.  The quantity of Crude Oil delivered during that period shall be determined by the first of the following methods which is available: |

| i) | by correcting the error if the percentage of the error is ascertainable by calibration, test or mathematical calculation; or |

|     |                                                                                                                                                                                          |
