          3.2 Capacity Not Warranted. Plant Supplier hereby specifically recognizes that the foregoing representations regarding the processing capacity of the Toca Plant are merely advisory and do not constitute a warranty by or obligation of Processor as to capacity. Plant Supplier further recognizes that the Determined Plant Capacity may change from time to time as the result of operating experience or performance tests or alterations made to the Plant by Plant Owners.

ARTICLE IV — DELIVERY AND REDELIVERY OF PLANT SUPPLIER’S GAS

          4.1 Gas to be Delivered by Plant Supplier. Commencing as of the Effective Date, Plant Supplier shall deliver to Processor at the Plant Delivery Point for processing hereunder all of Plant Supplier’s gas delivered to the Field Delivery Point(s) listed on Exhibit “E”, less and except Plant Supplier’s pro rata share of the gas which is used by Southern for compressor fuel, incidental sales of gas for drilling purposes and other routine and normal uses as may be necessary to the maintenance of leases or operation of Southern’s Lines and also any gas lost in the normal operation of Southern’s Lines upstream of the Plant Delivery Point, including, but not limited to, gas lost in pipeline blowdown for repairs or tie-ins, cleaning and purging and in pipeline scrubber operations. Such deliveries of gas shall be continued hereunder during the term hereof. The rights granted herein by Plant Supplier to Processor are exclusive, and Liquid Hydrocarbons shall not be stripped in the field or elsewhere from Plant Supplier’s gas subject hereto prior to delivery at the Toca Plant other than by usual field separation methods which may include adiabatic expansion utilizing the natural pressures available from the wells, but shall exclude facilities designed to recover Liquid Hydrocarbons including but not limited to solid bed absorption, lean oil absorption, turbo-expander or mechanical refrigeration principles. In no event shall Processor be liable to Plant Supplier if Southern fails for any reason to deliver Plant Supplier’s gas to the Plant for processing as above provided.

American Midstream (Louisiana Intrastate), LLC L1234		7		Execution Copy

          4.2 When Plant Supplier’s Gas is to be Bypassed. During periods when the Plant is shut down because of mechanical failure, force majeure or necessary maintenance or repairs, all of Plant Supplier’s gas being transported through Southern’s Lines shall be Bypassed Gas. When the Plant is partially shut down for any of the above-mentioned reasons, or if the Plant lacks sufficient capacity to handle all gas available for processing from Southern’s Lines, Plant Supplier’s gas shall be processed only on a space available basis, and to the extent that gas handling capacity in the Plant, for any reason, is not available for such gas, such gas shall be preferentially bypassed along with the gas of any other Third Party Suppliers which is made available for processing in the Plant. All of such gas bypassed preferentially will be determined monthly on an average daily basis and will be prorated to all Third Party Suppliers under their respective agreements in the ratio that the average daily volume of gas made available by each during the month bears to the total average daily volumes made available by all such Third Party Suppliers during the month; provided that, if any continuous period of complete shutdown of the Plant shall equal or exceed twelve (12) hours’ duration, the time of each such shutdown [determined to the nearest increment of six (6) hours] and the measured (or estimated, in the absence of measurement) volumes of gas bypassed during such determined period of shutdown shall be excluded in determining the average volume of Third Party Suppliers’ gas considered to have been bypassed during the affected month for purposes hereof.

          4.3 Redelivery of Plant Supplier’s Gas to Southern’s Lines. After processing Plant Supplier’s gas delivered hereunder to the Plant, Processor shall redeliver the Residue Gas to Southern’s Lines at the Plant Redelivery Point. The Residue Gas prior to being commingled with any Bypassed Gas shall have a total or gross heating value of not less than one thousand (1,000) BTU’s per cubic foot (gross heating value saturated with water vapor) and shall otherwise comply with the quality specifications enumerated in the contract heretofore executed by Plant Owners and Southern; provided that the combined gas stream delivered by Southern at the Plant Delivery Point meets such specifications.

          4.4 Production Estimates. Effective as of the date of this Agreement, Processor requires from Plant Supplier five (5) days prior to the start of each month gas composition analyses

American Midstream (Louisiana Intrastate), LLC L1234		8		Execution Copy

and monthly volume forecast, i.e. monthly wellhead production estimates, daily pipeline nomination volume, or other delivery point information for any Gas that may be delivered into Southern’s Lines, for each Field Delivery Point (expressed in MCF per day).

ARTICLE V — ALLOCATION OF PRODUCTS

          5.1 General. Products fractionated from the Raw Make recovered from gas processed in the Plant shall be allocated to the source of each Plant Owner’s Committed Gas and each Third Party Supplier’s gas in accordance with the procedure set forth in the following sections of this Article V, which procedure is illustrated by the example calculation set forth in Exhibit “A” hereto. As shown on said Exhibit, separate calculations shall be made for each Product. For the purposes of such allocations, Plant Supplier under this Agreement shall be allocated Products on the same basis as Products are allocated to Plant Owners. Processor will respond promptly to inquiries from Plant Supplier regarding daily operating rates and daily production rates at the Plant.

          5.2 “Plant Supplier’s Inert Constituents” Plant Supplier shall retain title to all Inert Constituents in the Natural Gas delivered by Plant Supplier under this Agreement (collectively, whether removed from the Natural Gas or not, “Plant Supplier’s Inert Constituents”), including but not limited to, carbon dioxide (CO2). To the extent that Processor removes Plant Supplier’s Inert Constituents from such Natural Gas and Plant Supplier has not made arrangements to utilize, market or dispose of Plant Supplier’s Inert Constituents, Processor may, but is not required to, dispose of some or all of Plant Supplier’s Inert Constituents by venting or other methods. If (i) venting Plant Supplier’s Inert Constituents is ever prohibited or disallowed for any reason or is deemed by Processor to be uneconomic, or (ii) additional costs are required to vent, dispose of or handle Plant Supplier’s Inert Constituents due to new rules, regulations or other laws, then Plant Supplier shall promptly (i) make alternate arrangements to utilize, market and/or dispose of Plant Supplier’s Inert Constituents at Plant Supplier’s sole cost and expense, (ii) notify Processor in writing and in reasonable detail of such alternate arrangements, and (iii) reimburse Processor for any costs incurred by Processor for delivering Plant Supplier’s Inert Constituents for such utilization, marketing and/or

American Midstream (Louisiana Intrastate), LLC L1234		9		Execution Copy

disposal. If Plant Supplier fails to comply with Plant Supplier’s obligations under the immediately preceding sentence, Processor shall be entitled, without further notice to Plant Supplier, to make arrangements for utilization, marketing and/or disposal of some or all of Plant Supplier’s Inert Constituents for Plant Supplier’s account and at Plant Supplier’s sole cost and expense; and Plant Supplier shall promptly reimburse Processor upon demand for any costs and expenses incurred by Processor in connection with such arrangements by Processor. PLANT SUPPLIER HEREBY RELEASES, INDEMNIFIES, DEFENDS AND HOLDS HARMLESS PROCESSOR AND PROCESSOR’S DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, AND CONTRACTORS FROM AND AGAINST ANY AND ALL CLAIMS, DEMANDS, DAMAGES, LIABILITIES, EXPENSES, ACTIONS, CAUSES OF ACTION, LIABILITIES, LOSSES, TAXES, PENALTIES AND FEES ARISING OUT OF OR IN ANY WAY RELATING TO (I) ANY OR ALL OF PLANT SUPPLIER’S INERT CONSTITUENTS, INCLUDING, WITHOUT LIMITATION, THE UTILIZATION, MARKETING OR DISPOSAL THEREOF, AND/OR (II) ANY PERSONAL INJURY, DEATH, PROPERTY DAMAGE, ENVIRONMENTAL DAMAGE, POLLUTION, OR CONTAMINATION ARISING OUT OF OR RELATING TO ANY OR ALL OF PLANT SUPPLIER’S INERT CONSTITUENTS.

          If any Taxes (as defined in Section 9.2), fees or other impositions are ever imposed on Plant Supplier’s Inert Constituents and/or the utilization, marketing or disposal thereof, Plant Supplier shall promptly pay such Taxes. If such Taxes must be paid by Processor, Plant Supplier shall promptly reimburse Processor for any and all such Taxes paid by Processor with respect to any or all of Plant Supplier’s Inert Constituents. If Processor is required by applicable law to pay such Taxes on any or all of Plant Supplier’s Inert Constituents and it is unlawful for Plant Supplier to make such reimbursement to Processor for such Taxes, Plant Supplier and Processor shall promptly negotiate and execute an amendment to this Agreement which restores to Processor the same economic bargain as would have resulted if Plant Supplier, rather than Processor, had paid all Taxes on Plant Supplier’s Inert Constituents; and if Plant Supplier is unable or unwilling to promptly enter

American Midstream (Louisiana Intrastate), LLC L1234		10		Execution Copy

into such an amendment reasonably acceptable to Processor, Processor shall have the option, exercisable in Processor’s sole discretion, to terminate this Agreement by written notice to Plant Supplier.

          5.3 Basic Allocation Data. The volumes of gas which shall be credited as having been processed in the Plant shall be the sum of all volumes of gas delivered to Southern at the various Field Delivery Points, less the volumes deducted pursuant to Section 5.5 hereof. Representative determinations for Liquid Hydrocarbons content of the gas shall be made of the gas streams at each Field Delivery Point by Plant Operator quarterly or more often if found necessary, by chromatographic analysis or by some other acceptable method for testing gas for Liquid Hydrocarbons content. Plant Operator shall give Plant Supplier reasonable advance notice of tests to determine Liquid Hydrocarbons content of the gas at the Field Delivery Point(s) for Plant Supplier’s account so that Plant Supplier may witness such tests if desired. Plant Supplier agrees that the gas stream(s) made available for these tests shall be representative of the stream(s) normally delivered at the Field Delivery Point(s) for Plant Supplier’s account and will be at as near average delivery conditions and volumes as possible at the time. Plant Operator or Plant Supplier may request a retest if dissatisfied with the results of a particular test. If the request for a retest is made by Plant Supplier and the Liquid Hydrocarbons content of the previous test is confirmed within ten percent (10%), the expense of the retest shall be borne by Plant Supplier.

          5.4 Allocation of Products to the Respective Field Delivery Points. Such aforesaid volumes of gas which are credited as having been processed and the theoretical Liquid Hydrocarbons content of such gas at the respective Field Delivery Points shall be used as the basis for allocating each Product fractionated from the Raw Make to such Field Delivery Points by the method illustrated in Exhibit “A”. Such method contemplates that the volume of theoretical Liquid Hydrocarbons (separately for each Product) for each such Field Delivery Point will be calculated by multiplying the volume of gas credited as having been processed from such Field Delivery Point by the theoretical Liquid Hydrocarbons content (separately as to each Product) at each such Field Delivery Point. The total of each such Product fractionated from the Raw Make will, in turn, be

American Midstream (Louisiana Intrastate), LLC L1234		11		Execution Copy

allocated to such respective Field Delivery Points in the ratio that the volume of theoretical Product calculated for each Field Delivery Point bears to the sum of the volumes of such theoretical Product calculated for all such Field Delivery Points. Any Liquid Hydrocarbons recovered by the Plant inlet scrubber for which the preferred disposition is at the Plant rather than being combined with the Raw Make, shall be allocated to the Field Delivery Points in the same proportions as natural gasoline Product is allocated.

          5.5 Field Volume Statements and Sub-Allocations at Field Delivery Points. As soon as practicable, but no later than the twentieth (20th) day of each month, Plant Supplier shall furnish, or cause to be furnished, to Plant Operator a gas purchase statement by Gas Transporter or such other statement as Plant Operator may reasonably require, to show the volume of gas delivered during the preceding month from each of the Field Delivery Points for Plant Supplier’s account. Additionally, by the twentieth (20th) day of each such month, but only when gas owned by more than one Plant Supplier (including for Plant Supplier’s account) has been delivered through a single Field Delivery Point, Plant Supplier, if so situated, shall furnish or cause the operator of the Field Delivery Point to furnish to Plant Operator written instructions on sub-allocating the gas delivered through said Field Delivery Point and Products attributable thereto for such preceding month. Plant Operator shall be entitled to rely on the information thus furnished or caused to be furnished in sub-allocating the Products recovered and allocated to the particular Field Delivery Point.

          5.6 Pipeline Uses and Losses. From the quantities of gas measured at the respective Field Delivery Points as provided above, there shall be deducted any gas which may be lost, used or sold by Southern at any place on Southern’s Lines between such Field Delivery Points and the Plant Delivery Point, as more specifically set forth in Section 4.1 above. It is agreed that the volumes of such gas and the nature of each disposition, as reported by Southern to Plant Operator, shall be subtracted by Plant Operator from the quantities of gas measured at the Field Delivery Points. In making settlements hereunder, Plant Operator shall be entitled to rely upon the accuracy of such information as reported to it by Southern, but Plant Operator shall footnote settlement data supplied

American Midstream (Louisiana Intrastate), LLC L1234		12		Execution Copy

to the affected Plant Suppliers, noting the allocable amount of gas lost, used or sold by Southern. It is understood that the aforesaid volumes of gas lost, used or sold by Southern at any place on Southern’s Lines shall be allocated to all Field Delivery Points serving Southern’s Lines (including those Field Delivery Points serving the Lines from which gas will be processed in plants other than the Toca Plant) in the ratio which the volume of gas measured at each such Field Delivery Point during a month bears to the total volume of gas measured at all Field Delivery Points serving Southern’s Lines during the month.

          5.7 Product Allocation Statements. By the end of the month in which the information referred to in the preceding two sections is received, Plant Operator shall furnish a statement to all Plant Owners and Third Party Suppliers accounting for the volume of gas delivered from each Field Delivery Point for the preceding month together with the amount of each individual Product allocated to said gas.

          5.8 Measurement of Field Volumes. All gas delivered at a Field Delivery Point shall be measured by a suitable orifice meter or meters of standard make furnished, installed, operated and kept in repair by the owners of the equipment at the point where delivery is made to Southern’s Lines which shall be the same meter or meters used under the provisions of each Plant Owner’s or Third Party Supplier’s individual gas purchase contract with Gas Transporter. The volumes measured by said meter or meters shall be used for purposes of settlement under this agreement. The computation of all gas volumes measured by orifice meters shall be based on the latest orifice factors published by the American Gas Association corrected to a base pressure of 15.025 pounds per square inch absolute and at a base temperature of sixty degrees Fahrenheit (60°F), and the measurement procedures, technical requirements and standards for all such meters shall be as set out in each Owner’s or Plant Supplier’s gas transportation contract. Plant Supplier agrees that the Plant Operator shall have the right to witness all tests of the meters and other equipment employed to measure volumes of gas delivered to Gas Transporter, and upon request, Plant Supplier shall give Plant Operator reasonable advance notice of all such tests.

American Midstream (Louisiana Intrastate), LLC L1234		13		Execution Copy

ARTICLE VI — CONSIDERATION DUE PLANT SUPPLIER

          6.1 Plant Supplier’s Consideration. Plant Supplier shall receive as full settlement hereunder each month ninety percent (90%) of the Net Proceeds attributable to such Gas for such month, as allocated to Plant Supplier’s Gas under Article VI hereof, less the Plant Share. Processor shall be entitled to ten percent (10%) of the Net Proceeds attributable to such Gas for such month (“Processor’s Proceeds”).

          Notwithstanding the foregoing, in no event shall the value of the Processor’s Proceeds be less than the value of $0.10 per MCF multiplied by the MCF of the Plant Supplier’s Gas at the Field Delivery Point.

ARTICLE VII — PLANT VOLUME REDUCTION AND BYPASSED GAS

          7.1 General. It is recognized that there will be a reduction in gas volumes, herein called “Plant Volume Reduction”, between the quantity of gas delivered by Southern for processing in the Plant and the volume of Residue Gas returned to Southern’s Lines because of (a) extraction of Raw Make, herein called the “shrinkage portion”, and (b) Plant fuel used, flared gas or other uses or losses incident to or occasioned by processing.

          7.2 Calculation of Plant Volume Reduction. The Plant Volume Reduction for the entire Plant shall be accounted for on a monthly basis and shall be calculated as follows:

          7.2.1 Shrinkage Portion. The vapor volume equivalent of each liquid component of the Raw Make shall be determined by multiplying the liquid volume of such component by the applicable vapor equivalent factor set forth in the schedule below. The total shrinkage portion of the Plant Volume Reduction will be equal to the sum of all such conversion computations made for each component of the Raw Make. Until revised by Plant Owners and Gas Transporters, the vapor equivalent factors set forth in the schedule below shall be used for all such conversion calculations:

American Midstream (Louisiana Intrastate), LLC L1234		14		Execution Copy

		VAPOR EQUIVALENT				HEAT EQUIVALENT
COMPONENTS		FACTOR (CF/GAL)				FACTOR (MMBTU/GAL)
Carbon Dioxide			57.8528				0.000000
Methane			57.8431				0.059729
Ethane			36.6672				0.066338
Propane			35.5942				0.091563

Iso-Pentane			26.8137				0.109679
N-Pentane			27.0524				0.110869
Hexane			23.8466				0.115952
Heptanes Plus*

Taken from Gas Processors Association (“GPA”) Publication 2145-09. Vapor Equivalent factors are in cubic feet per gallon on the Ideal Gas Basis corrected from 14.696 psia to 15.025 psia. Such factors shall be modified from time to time to conform with any amendment or revision of the above table adopted by the GPA. Heat Equivalent factors are in MMBTU per Gallon. Such factors shall be modified from time to time to conform with any amendment or revision of the above table adopted by the GPA.

The Gas/liquid ratio for heptanes plus shall be determined from time to time as may be necessary to be representative of such components.

The total shrinkage portion of the Plant Volume Reduction will be determined from measurement by positive displacement liquid meter and monthly composite sampling and analysis of the Raw Make.

          7.2.2 Determination of Losses. Plant fuel, flared gas and other uses or losses incident to processing: The volume of gas which is attributable to such uses or losses shall be as determined by the measurement with meters of each such use occurring in the Plant as may be necessary to determine accurately the total volume of gas so used, such meters to be installed and operated as mutually agreed by Plant Owners and Southern.

          7.2.3 Plant Volume Reduction Determination. All Plant Volume Reduction attributable to any other Plant use, loss or operation shall be determined by a method mutually agreeable to Plant Owners and Southern. It is understood that Plant Owners and Southern may agree on some other method of determining Plant Volume Reduction in order to remove any

American Midstream (Louisiana Intrastate), LLC L1234		15		Execution Copy

inequities which may be found to exist, and it is agreed that any such other method adopted shall be applicable to this agreement.

          7.3 Sharing of Plant Volume Reduction Among Plant Owners and Third Party Suppliers. That portion of Plant Volume Reduction resulting from Plant fuel shall be the volume measured by orifice meters. The metered fuel volume shall be allocated to the respective Field Delivery Points of Plant Owners and Third Party Suppliers on the following basis: One-half (1/2) in the same ratio that the sum of the gallons of propane and heavier Products (calculated separately for each Product) allocated to each Field Delivery Point bears to the sum of the gallons of propane and heavier Products (calculated separately for each Product) allocated to all Field Delivery Points, and one-half (1/2) in the ratio that the volume of gas processed from each such Field Delivery Point bears to the total volume of gas processed in the Plant. That portion of the Plant Volume Reduction remaining, after subtracting the metered fuel volume, shall be allocated to the respective Field Delivery Points of Plant Owners and Third Party Suppliers in the same ratio that the sum of the vapor equivalent of all Products (calculated separately for each Product) allocated to each Field Delivery Point bears to the sum of the vapor equivalent of all Products (calculated separately for each Product) allocated to all Field Delivery Points to the Plant.

          7.4 Accounting to Gas Transporter for Plant Volume Reduction. Plant Supplier shall bear and shall account to Gas Transporter for the full amount of Plant Volume Reduction allocated to the gas credited as having been processed from the Field Delivery Points for Plant Supplier’s account monthly on such basis as may be provided in the applicable contract between Plant Supplier and Southern, or between the Gas Transporter and Southern, it being expressly understood that Plant Owners have no responsibility for any portion of such Plant Volume Reduction allocated pursuant hereto to the Field Delivery Points for Plant Supplier’s account. Plant Operator shall, by the end of the month in which it receives the accounting data required to be furnished by Plant Supplier under Section 5.5 and such additional accounting data as may be required from Plant Owners, other Suppliers and Southern, furnish Plant Supplier and other interested parties a statement setting forth:

7.4.1 The total quantity of Plant Volume Reduction; and

American Midstream (Louisiana Intrastate), LLC L1234		16		Execution Copy

7.4.2 Each Plant Owner’s and Third Party Supplier’s proportionate share of the total Plant Volume Reduction; and

7.4.3 An allocation of the Plant Volume Reduction applicable to each Field Delivery Point serving the Plant, and a sub-allocation as to gas which is owned by more than one Plant Supplier (including for Plant Supplier’s account) to show the amount of Plant Volume Reduction attributable to each Owner of the gas delivered at such Field Delivery Point.

The results set forth in such statement each month shall constitute the quantity of Plant Volume Reduction to be allocated to each Plant Owner and Third Party Supplier for the preceding month, and it is understood that Gas Transporter may rely on such statements in effecting settlement with Plant Supplier for Plant Supplier’s share of Plant Volume Reduction. Plant Operator shall furnish the foregoing parties with an allocation statement based on estimated Plant Volume Reduction covering the first month of Plant operation. Plant Operator’s statement shall also report the volume of gas bypassed at the Plant during the preceding month and allocation thereof to Plant Owners and/or Third Party Suppliers, including Plant Supplier.

          7.5 Determination of Bypassed Gas. Plant Owners shall install an orifice meter on the Plant bypass line for the purpose of measuring gas bypassed as herein provided, such meter to be installed, operated and measurement made thereby in conformity with the requirements agreed upon by Plant Owners and Southern.

FRACTIONATION FEE

Beginning on the effective date of this Agreement, and on the first day of each month thereafter with respect to fuel gas, the Fractionation Fee shall be calculated based on the following formula (expressed in cents/Gallon):

		(W)(1.20)   $4.00/MMBTU		+ 2.40 =		Fractionation Fee ¢/Gallon

     With respect to the formula above, the following definition shall apply:

W = The settlement price in dollars per MMBtu, for the Henry Hub index (“Index”), as published in Inside F.E.R. C.’s Gas Market Report (“IFERC”), in effect for the month in which the Gas is being processed (e.g. IFERC price published on/near last day of February for March gas flows).

Notwithstanding anything to the contrary herein, in no event shall the adjustments permitted by the formula appearing above in this Agreement reduce the Fractionation Fee below 3.60 cents ($0.0360) per gallon (the “Fractionation Fee Floor”). In the event that the computation of the Fractionation Fee, as herein provided, results in an amount that is less than the 3.60 cents ($0.0360) per gallon, then the Parties acknowledge and agree that the Fractionation Fee shall be 3.60 cents ($0.0360) per gallon. In the event that anything in this Agreement conflicts or otherwise restricts the application of the Fractionation Fee Floor, the Fractionation Fee Floor shall fully apply and control.
