2.2 Specific Gravity - The gas delivered by Transporter to

Shipper shall not have a specific gravity greater than

0.77 or less than 0.625 when compared with dry air at the

same temperature and pressure, air being taken as 1.0;

provided, however, the specific gravity may vary beyond

such limits if approved by Shipper.
