5. MONTHLY BILL (continued)

If a Shipper's total Excess Contract Quantities under Rate

Schedule PHS are less than both 50 Dth and ten percent (10%)

of its authorized quantity for the applicable period,

Shipper shall not be assessed an Excess Contract Quantities

charge; provided, however, that such exemption shall not be

applicable in the event of curtailment or if Transporter has

invoked the provisions of Section 20 of the General Terms

and Conditions. For a Service Month in which Excess

Contract Quantities are transported, Shipper shall be billed

the sum of the products of (x) the Excess Contract

Quantities within each of the above specified percentage

ranges, multiplied by (y) the applicable Excess Contract

Quantities Rate, as specified in Transporter's Statement of

Effective Rates and Charges for Transportation of Gas

contained in this Tariff. In the event that Transporter has

invoked the provisions of Section 20 of the General Terms

and Conditions, the higher charges shown on Transporter's

Statement of Effective Rates and Charges for Transportation

of Gas for the Excess Contract Quantities will be assessed.

If Transporter has not invoked the provisions of Section 20

of the General Terms and Conditions, it will not assess

Excess Contract Quantities penalties until it has first

given the affected Shipper(s) twenty-four (24) hours'

notice, which notice shall be, in Transporter's sole

discretion notwithstanding any other provisions contained in

this Tariff, via facsimile, telephone (including a message

via voice mail or other messaging) or e-mail, or otherwise

during the scheduling process via the Internet. Transporter

may waive all or part of any such charges.

(b) Failure to Return Loaned Quantities: In accordance with the

provisions of Section 2.8(a) above, if Shipper fails to

return loaned quantities when required to do so under this

Rate Schedule, Shipper shall be billed an amount determined

by multiplying the quantities which Shipper failed to return

by the higher of the Return Deficiency Charge for the Month

of the loan, or the Month in which return was required.

Imbalances, Shipper shall be billed as described in Section

5.7 of the General Terms and Conditions.
