GENERAL TERMS AND CONDITIONS

3. QUALITY (Cont'd)

If, at any time, gas tendered to WNG shall fail to substantially

conform to any of the applicable quality specifications and WNG

notifies the Shipper of such deficiency, and such deficiency is

not corrected within a reasonable period of time, WNG may, at its

option, refuse to accept delivery pending correction of the

deficiency by Shipper or continue to accept delivery and make

such changes necessary to cause the gas to conform to such

specifications, in which event, prior to making such changes, WNG

shall provide Shipper with an estimate of the costs that are

expected to be incurred by WNG in effecting such changes and

Shipper shall agree to reimburse WNG for all such costs incurred

by WNG in effecting such changes; provided, however, that WNG may

at any time refuse to accept delivery of gas which it considers

to be unsafe or hazardous or to impair the operation or use of

its facilities. Failure by Shipper to tender deliveries that

conform to any of the applicable quality specifications shall not

be construed to eliminate, or limit in any manner, the rights and

obligations existing under any other provisions of the executed

Service Agreement.
