regarding transportation service on COMPANY'S system within forty-eight (48) hours

after receipt by COMPANY. If such complaint is not resolved within thirty (30) days

after COMPANY'S receipt of the complaint, COMPANY shall respond in writing to

the complaining party prior to the expiration of said thirty-day period.

27. ELECTRONIC BULLETIN BOARD

COMPANY shall maintain an interactive bulletin board via the public internet

("SoNet Premier") for the purpose of providing its SHIPPERS and third parties equal

and timely access to COMPANY'S Transportation Log, Standards of Conduct,

including applicable postings, Index of Customers, information relevant

to the availability of capacity on COMPANY'S system, whether the capacity is

available from COMPANY or a RELEASING SHIPPER under the provisions of Section 22

hereof, and reports on COMPANY's firm and interruptible services pursuant to Section

284.13 of the Commission's Regulations. COMPANY shall also provide each SHIPPER

access through SoNet Premier to information related to activity under its agreements with

COMPANY, such as nominations, estimated imbalances and storage inventory. In addition,

COMPANY will provide through SoNet Premier a daily report showing pipeline capacity,

daily metered flow as available, and daily scheduled quantities aggregated by receipt

point groups within capacity constrained areas. Furthermore, COMPANY shall administer

each SHIPPER'S release of firm capacity, as more particularly described in Section 22

hereof, exclusively through SoNet Premier and shall provide to SHIPPER other

interactive capabilities such as the ability to request service, amendments,

discounts or negotiated rates, submit nominations, confirmations, and PDAs, view agent appointments

under SHIPPER'S service agreement(s), and execute service agreements and amendments thereto.

It is understood and agreed that COMPANY, through SoNet Premier, shall make available

to SHIPPERS or working interest owners sufficient details to support the quantities allocated

to that party under the PDA method at each point.

Unless specifically provided otherwise in this FERC Gas Tariff, the generic

provisions of this Tariff requiring that notices, requests, and other communications

be in writing may be satisfied by SHIPPER through submission of such

communications over SoNet Premier. All forms set forth or referenced in the Tariff will also

be maintained on SoNet Premier for SHIPPER'S use. Service-agreement specific notices

requiring communications to be in writing remain unchanged unless agreed to

otherwise by the parties. Submission of information, communications, and execution

of documents through SoNet Premier shall be legally binding on SHIPPER. COMPANY will

also require written execution of firm Service Agreements by SHIPPER for its

records.
