permanently for the remaining term of the agreement,

subject to MGS' agreement, the Releasing Shipper shall

have no further responsibility or obligations under the

Service Agreement.

(b) If the aforementioned condition is not met, then the

Releasing Shipper shall continue to be responsible to MGS

for all reservation charges, including reservation

surcharges, applicable to the Service Agreement unless

MGS agrees otherwise. A credit will be included on each

of the Releasing Shipper's monthly bills to reflect the

reservation fee(s) invoiced to the Replacement Shipper.

to the new tolerance level in the month following the

completion of the assignment to avoid any balancing
