3. QUALITY

(a) May Be Processed Gas

Moisture, impurities, helium, natural gasoline, butane, propane, and any other

hydrocarbons except methane may be removed from the natural gas delivered to or for

the account of Buyer prior to such delivery. Seller may subject, or permit the

subjection of, the natural gas to compression, cooling, cleaning and other processes.

(b) Heating Value

The natural gas delivered by Seller to or for the account of Buyer or delivered by

Buyer or Buyer's Supplier to Seller for redelivery shall have a daily average Heating

Value of not less than 980 Btu per cubic foot and not more than 1100 Btu per cubic

foot as determined in Section 2(d).

The natural gas delivered by Seller to or for the account of Buyer or delivered by

Buyer or Buyer's Supplier to Seller for redelivery:

(i) Shall be commercially free from objectionable odors, dust, or other solid or

liquid matter which might interfere with its merchantability or cause injury to

or interference with proper operation of the lines, regulators, meters or other

appliances through which it flows;

(ii) Shall contain not more than three-tenths (.3) grain of hydrogen sulphide per

100 cubic feet of gas volume when tested in accordance with the following

procedure: A strip of white filter paper previously moistened with fresh 5

percent lead acetate solution shall be exposed to the gas for one and one-half

minutes in a previously purged apparatus through which the test gas is flowing

at a rate of approximately 5 cubic feet per hour; the gas jet shall not

directly impinge upon the test strip during the test. At the end of the stated

time the test paper thus exposed shall be compared with a second test strip

similarly prepared but not exposed to the test gas. If the exposed strip is

not noticeably darker than the comparison strip, the gas under test shall be

considered acceptable. If the exposed strip is noticeably darker than the

comparison strip, the gas shall be tested quantitatively for hydrogen sulphide

by the Tutweiler or other approved method;

(iii) Shall not contain more than twenty (20) grains of total sulphur per hundred

cubic feet of gas volume;

(iv) Shall contain odorant at the point of delivery and, if necessary, be odorized

at an agreed to injection point to obtain an adequate intensity, as defined at

49 C.F.R. 192.625 as amended from time to time, except where (1) the

transportation and delivery by Seller of unodorized gas is permitted under

applicable laws, rules or regulations and (2) Buyer requests and Seller agrees,

in writing, that gas delivered to Buyer shall not be odorized and Buyer

performs the odorization or causes the odorization to be performed if required.

In the event of (2) above, Buyer agrees to and shall indemnify Seller from and

against all claims, damages and liabilities arising out of or related in any

way to the delivery by Seller of unodorized gas to Buyer. Odorization by

Seller shall not be construed as interfering with the merchantability of gas

delivered;

(v) Shall not be delivered at a temperature of more than 120 degrees Fahrenheit;

and

(vi) Shall not contain in excess of seven (7) pounds of water vapor per million

cubic feet.
