FORM OF PREDETERMINED ALLOCATION AGREEMENT

(continued)

General Terms and Conditions. The applicable provisions of this Agreement

shall be suspended as necessary to allow Shippers utilizing the

interconnection locations specified on Exhibit A to comply with any

Operational Flow Order issued by REGT.

REGT shall have the right to terminate this Agreement immediately in the event

that it deems PDA Operator's Imbalance at any time to be excessive and to take

such other action as REGT may deem appropriate to alleviate such Imbalance.

Either party shall have the right to terminate this Agreement at any time upon

forty-eight (48) hours written notice or electronic notice via the Internet as

permitted or required by REGT; provided, however, that termination shall not

relieve either party of any obligations that might otherwise exist to cash-out

or correct any Imbalance hereunder and any portions of this Agreement

necessary to accomplish such purposes shall be deemed to survive to the extent

required.
