GENERAL TERMS AND CONDITIONS

____________________________

(continued)

Subscriber shall not disclose to persons other than Authorized Persons, and shall keep

completely confidential, all USERIDs and passwords issued to Subscriber by Great Lakes. In addition,

each Authorized Person shall not disclose to any other person, and shall keep completely

confidential, the individualized USERID and password issued to such Authorized Person. Subscriber

shall be solely responsible for any and all improper use of USERIDs and passwords related to any such

unauthorized disclosure by Subscriber, or former or current Authorized Persons of Subscriber.

Subscriber shall immediately inform Great Lakes in writing whenever it desires: (1) to

terminate access to GLConnect that has been previously granted to any Authorized Person, or (2) to

terminate or to limit the status of any Authorized Person. Subscriber shall be solely responsible

for any and all unauthorized or otherwise improper use of USERIDs and passwords by Authorized Persons

that at some point are no longer employed or controlled by Subscriber. Great Lakes reserves the

right, upon cause, to invalidate any password or USERID. Great Lakes will provide notice and inform

the Subscriber as to the reason for the invalidation.

Neither Subscriber nor Great Lakes shall be liable in damages to the other for any act, omission

or circumstance occasioned by or in consequence of: any acts of God, strikes, lockouts, acts of the

public enemy, wars, blockades, insurrections, riots, epidemics, landslides, lightning, earthquakes,

fires, storms, floods, washouts, arrests and restraints of rulers and peoples, civil disturbances,

explosions, breakage or accident to machinery, computer hardware, computer software or lines of pipe,

line freezeups, failure of electronic communication, or the binding order of any court or

governmental authority that has been resisted in good faith by all reasonable legal means, and any

other cause, whether of the kind herein enumerated or otherwise, and whether caused or occasioned by

or happening on account of the act or omission of Subscriber or Great Lakes or some other person or

concern, not within the control of the claiming party and that by the exercise of due diligence such

party is unable to prevent or overcome. A failure to settle or to prevent any strike or other

controversy with employees or with anyone purporting or seeking to represent employees shall not be

considered to be a matter within the control of the party. Such causes or contingencies affecting

the performance of this agreement by Subscriber or by Great Lakes shall not relieve it of liability

in the event of its concurring negligence or in the event of its failure to use due diligence to

remedy the situation and remove the cause in an adequate manner and with all reasonable dispatch.

Designation of Business Method for Nominate, Confirm, and View Imbalance Statement Business Functions

For each of the Nominate, Confirm, and View Imbalance Statement business functions, Subscriber

has the option of utilizing either the "Basic View" or "Alternate View" methods. Once Subscriber has

used one of these two methods to perform a particular business function for services to be provided

in any calendar month, the Subscriber will be required to use that same method to perform that same

business function for the remainder of that calendar month. The alternate method for that particular

business function will be disabled for services for Subscriber in that calendar month. For example,

if Subscriber enters a nomination utilizing the Basic View method and a confirmation utilizing the

Alternate View method for the first gas day of November, then, for the remainder of November

business, Subscriber must nominate using the Basic View method and confirm using the Alternate View

method.

If Subscriber has executed a Trading Partner Agreement with Great Lakes, Subscriber may utilize

Electronic Data Interchange (EDI) for any business function for which it is using the Basic View

method. Subscriber may not, however, utilize EDI for any business function for which it is using the

Alternate View method, regardless of whether or not it has executed a Trading Partner Agreement with

Great Lakes.
