GENERAL TERMS AND CONDITIONS

(Continued)

4.3.15 Trading partners should implement all security features (secure

authentication, integrity, privacy, and non-repudiation) using a

file-based approach via a commercially available implementation of

PGP 2.6 or greater (or compatible with PGP 2.6). Trading partners

should also implement basic authentication. This should be regarded

as an interim solution since this technology is not an open

standard. This technology supports all of the above security

features while providing independence of choice of Web servers and

browsers. Encryption keys should be self-certified and the means of

exchange should be specified in the trading partner agreement.

4.3.16 The documents identified in GISB Standard 4.3.6 should be made

available in HTML or RTF format.

5.2.1 Critical notices should be defined to pertain to information on

transportation service provider conditions that affect scheduling or

adversely affect scheduled gas flow.

5.3.9 If the transportation service provider requires amendments for each

release, the transportation service provider should automate the

process of amending contracts and this may be the subject of a global

agreement between the parties.

5.3.10 Capacity Release service providers should support the upload of

prearranged deals.

5.3.11 Replacement shipper initiates confirmations of prearranged deals

electronically.

5.3.17 Transportation service providers should provide on request

operationally available capacity separate from unsubscribed capacity.

5.3.18 System-wide notices should have a separate category for notices that

are not critical.

5.3.21 On the bidding formats, the number of decimal places for offers, bids,

and awards should be equal to the number of decimal places in the

stated rates per pipeline rate schedule.

5.3.22 For less than maximum rate transactions only, converting daily rate to

monthly rate is accomplished by multiplying the daily rate times

number of days in rate period, dividing the result by number of months

in rate period and taking the remainder out to 5 decimals places and

rounding up or down to the transporter’s specified decimal place.

Converting a monthly rate to a daily rate is accomplished by

multiplying the monthly rate by number of months in rate period;

dividing the result by number of days in rate period and taking the

remainder out to 5 decimals places and rounding up or down to the

transporter’s specified decimal place.

5.3.23 All tariff rates should be adjusted to reflect a standard calculation

of daily and monthly rates.

5.3.25 A releasing shipper should not be able to specify an extension of the

original bid period or the pre-arranged deal match period, without

posting a new release.

5.3.26 Releasing shipper has the choice to specify dollars and cents or

percents of maximum tariff rate in the denomination of bids, and all

transportation service providers should support this. Once the choice

is made by the releasing shipper, the bids should comport with the

choice.
