5.4 In addition, El Paso agrees to grandfather the sulfur

specifications set forth in Section 5.1(c) above for natural gas

received at the tailgate of the Terrell and Puckett Plants, based

on the actual monthly highest non-conforming concentrations during

the twelve (12) month base period ending July 31, 1990. The

sulfur specifications El Paso shall accept for natural gas at

volumes up to the residue volume at plant design capacity received

at the tailgate of the Terrell and Puckett Plants are identified

below. To the extent a Shipper can demonstrate to El Paso that

any other plant located on El Paso's system has not historically

met the sulfur specifications set forth in Section 5.1(c) above,

El Paso shall grandfather such plant on the same basis as the

Terrell and Puckett Plants; provided, however, a plant shall not

qualify if such plant has changed the method of processing the gas

in the last five (5) years.
