8. Pressures.
The Gas delivered by Shipper to the Receipt Points hereunder shall be 
delivered at a pressure sufficient to overcome the operating pressure 
existing in Houston's facilities from time to time; provided, however, in no 
event shall such pressures ever exceed the Maximum Allowable Operating 
Pressure ("MAOP") and Shipper shall at its sole cost and expense ensure that 
all documentation and data required by the applicable regulatory authority 
with regard to Shipper's or Shipper's supplier's overpressure protection 
facilities upstream of the Delivery Point are made available and updated on 
an annual basis throughout the term of this Agreement.  If Shipper fails to 
comply with the foregoing covenant, Houston may, at Shipper's sole cost and 
expense, install such overpressure protection facilities (either upstream or 
downstream of the metering facilities, as Houston may elect) in order to 
ensure compliance with applicable laws and regulations.  The Gas delivered by 
Houston to the Delivery Points shall be delivered at the pressure existing in 
Houston's facilities from time to time.
9. Quality.
Shipper agrees that all Gas received by Houston at the Receipt Points 
hereunder and Houston agrees that all Gas delivered hereunder to or for the 
account of Shipper at the Delivery Points hereunder shall be merchantable Gas 
which shall:
a. Have a total heating value of not less than nine hundred fifty (950) 
British Thermal Units per cubic foot when saturated with wator vapor (gross 
basis);
b. Be commercially free of all dust, hydrocarbon liquids, water, suspended 
matter, all gums and gum forming constituents and any other objectionable 
substances;
c. Not contain more than twenty (20) grains of total sulfur, nor more than 
one-fourth (1/4) grain of hydrogen sulfide per one hundred (100) standard 
cubic feet at the Receipt Points nor more than one (1) grain of hydrogen 
sulfide per one hundred (100) standard cubic feet at the Delivery Points;
d. Contain no more than two percent (2%) by volume of carbon dioxide, two 
tenths of one percent (0.2%) by volume of oxygen, and three percent (3%) by 
volume of total inerts;
e. Have a temperature of not more than one hundred twenty degrees Fahrenheit 
(120F.) or less than forty degrees Fahrenheit (40F.);
f. Not contain more than seven (7) pounds of entrained water vapor per 
million cubic feet; and
g. Have a hydrocarbon dewpoint of 45"F or less at pipeline operating 
pressures between 200 psig and 1100 psig.
Shipper shall be responsible for odorizing any part of the Gas delivered 
hereunder to or for Shipper's account which is diverted and/or used by 
Shipper for any purpose for which odorization is required pursuant to 
regulations of the Railroad Commission of Texas.
Should the Gas delivered to either party hereunder fail to meet the quality 
specifications above, either party shall notify the other and the party 
responsible for the deficiency shall make a diligent effort to correct such 
failure.  The party receiving the deficient Gas shall have the right to 
refuse to accept such Gas for so long as the other party is unable to deliver 
Gas conforming to such specifications, or either party may accept delivery of 
such Gas or any part thereof during such period.  Should either party's 
tender of deficient Gas hereunder extend for a period greater than sixty (60) 
Days, the receiving party shall have the right and option at the end of such 
sixty (60) Days, and as long thereafter as the other party continues to 
tender such non-conforming Gas, to terminate this Agreement on twenty-four 
(24) hours advance written notice to the other party stating the effective 
date of such termination.
10. Metering Facilities and Measurement.
Except as otherwise agreed by Houston, the metering facilities to measure the 
volumes of Gas delivered at each Receipt Point and Delivery Point shall be 
maintained and operated or caused to be maintained and operated by Houston.  
The Btu content of the Gas shall be determined by the facilities at the 
Receipt Points and Delivery Points.  Such facilities and measurement data 
with respect to the Gas covered hereby shall at all reasonable times be 
subject to joint inspection by the parties hereto.  Gas volumes measured with 
the use of orifice meter(s) shall be determined in accordance with the 
provisions of the Gas Measurement Committee Report No. 3 of the American Gas 
Association, as revised in 1985 and as amended and/or supplemented from time 
to time, and Gas volumes measured with the use of positive meter(s) shall be 
determined on the basis of Gas Measurement Committee Report No. 7 of the 
American Gas Association, as revised in 1981 and as may be amended and/or 
supplemented thereafter from time to time.  The unit of volume for 
measurement of Gas delivered hereunder shall be one (1) cubic foot of Gas at 
a base temperature of sixty degrees Fahrenheit (60F.) and at an absolute 
pressure of fourteen and sixty-five one hundredths (14.65) pounds per square 
inch absolute.  Atmospheric pressure for each of the Receipt Points and 
Delivery Points shall be assumed to be the pressure value determined by 
Houston for the county in which such point is located pursuant to generally 
accepted industry practices (but not less than 14.1 psia nor more than 14.7 
psia) irrespective of the actual atmospheric pressure at such points from 
time to time.  Temperature shall be determined by a recording thermometer of 
standard make.  If recording charts are used, the arithmetical average of the 
temperature recorded during periods of flow for each chart, the factor for 
specific gravity according to the latest test therefor, and the correction 
for deviation from Ideal Gas Laws applicable during each chart period shall 
be used to make proper computations of volumes hereunder.  If electronic flow 
measurement is used, continuous temperature, static pressure and differential 
pressure monitoring will be applicable.  If electronic measurement is used in 
conjunction with on-site chromatograph, continuous monitoring of specific 
gravity will be applicable; otherwise the volumes computed using a fixed 
value specific gravity factor shall be corrected to reflect the actual 
specific gravity of the flowing Gas as determined by a chromatographic 
analysis of the sample accumulated during the same period of flow or, in the 
case of spot samples, the specific gravity factor determined by 
chromatographic analysis shall be applied to volumes delivered during the 
succeeding chart periods.  The correction for deviation from the Ideal Gas 
Laws shall be computed and applied to volumes calculated by electronic 
measurement devices.  Specific gravity and Btu shall be determined by such 
methods as may be developed by Houston through use of a continuous Gas sample 
accumulator, on premises analysis, or by spot samples taken at the Receipt 
Points and Delivery Points at intervals determined to be appropriate by 
Houston.  Results from a continuous sampler shall be used to calculate 
volumes delivered during the same period in which the sample was accumulated; 
provided, however, that Houston reserves the right to adopt the practice of 
using the Btu content measured for a period prior to the Month of Gas flow in 
calculating the quantity of Gas transported during a given Month.  Results 
from a spot sample shall be used to calculate volumes during the subsequent 
period until another sample is taken.  The arithmetical average of the 
continuous temperature recorded during each chart period, the factor for 
specific gravity according to the latest test therefor, and the correction 
for deviation from Ideal Gas Laws applicable during each chart period shall 
be used to make proper computations of volumes hereunder.  The gross heating 
value (Btu content) used shall be determined by adjusting the Btu content 
measured to reflect the actual water vapor content of the Gas delivered at a 
temperature of sixty degrees Fahrenheit (60F.) at an absolute pressure of 
fourteen and sixty-five one-hundredths (14.65) pounds per square inch 
absolute.  If the water vapor content of the Gas delivered is equal to or 
less than seven (7) pounds per one million cubic feet (1,000 Mcf), the Gas 
shall be considered dry.  The volume of Gas measured shall be multiplied by 
the applicable Btu content for such Gas (either that measured for the Month 
of Gas flow or for the designated period of Btu measurement that may occur 
prior to the actual Month of Gas flow) to determine the total volume of Gas 
in MMBtu.  In the event that the aggregate quantity of Gas tendered by 
Shipper and accepted by Houston under this Agreement during any Month at a 
given Receipt Point equals a quantity less than the product of (i) 300 MMBtu 
per Day times (ii) the number of Days in the Month during which Shipper 
tendered Gas to Houston in accordance with a confirmed nomination, then 
Houston may, at its election, charge Shipper a metering fee ("Metering Fee") 
of $350 for such Month with respect to each such Receipt Point.
