GENERAL TERMS AND CONDITIONS

(Continued)

3.5 (continued)

Transporter shall have the right to allocate that portion of the commingled stream to

Shipper, or for its account, attributable to the transportation service provided under the

Agreement.

3.6 (a) Use of PDAs: On a daily basis at each Delivery Point, Transporter

shall allocate any variances between scheduled nominations and the quantities of gas metered at the

point among the quantities of gas scheduled at the point for the account of its SHIPPERS based on

the Pro Rata PDA method unless another PDA method is provided by the party that owns or

operates the downstream facilities interconnecting with Transporter's facilities at each

Delivery Point (the "downstream operator"). The alternate PDA methodologies from which

the downstream operator may choose include the Swing PDA, a Ranked PDA, a Percentage PDA,

or any other mutually agreeable allocation methodology. A new allocation detail may be

needed when a nomination changes. The PDA shall be provided by the downstream operator

on a line item basis at the level of nomination detail provided by Transporter for

confirmation. Transporter shall then use the predetermined priority provided by

SHIPPER in its nomination for applying the PDA to the Package ID level within the line

item nomination level. SHIPPER agrees that Transporter shall have the right to

rely conclusively on the PDA provided pursuant to this Section 3.6 for the purpose of

determining the daily quantities of gas delivered by Transporter for the account of SHIPPER at

each Delivery Point.

(b) PDA Deadlines: Each PDA must be submitted to Transporter

by facsimile machine or through SoNet Premier during the confirmation of that day's nominations

or after confirmation but prior to start of gas day; provided that any revisions to the

PDA may be made by the downstream operator during the confirmation period on the day of

flow for intraday nomination changes. If there are no additions in nominations by a SHIPPER at

a Delivery Point or other changes, the current PDA will stay in effect as submitted until it is

changed pursuant to the foregoing procedures. In the event SHIPPER adds a nomination at a

Delivery Point, then SHIPPER must provide, or cause to be provided, as set forth above a PDA

at the Delivery Point which recognizes the SHIPPER'S nomination.
