The information regarding Williams’ principal accounting fees and services required by Item 9(e) of Schedule 14A will be presented under the heading “Principal Accountant Fees and Services” in the Proxy Statement, which information is incorporated by reference herein. Fees for professional services provided by Transco and NWP’s independent registered public accounting firm in each of the last two fiscal years in each of the following categories are (in millions):

Transco

NWP

Fees for audit services include fees associated with the annual audit, the reviews for Transco and NWP’s quarterly reports on Form 10-Q, the reviews for other SEC and FERC filings, and accounting consultation.

As wholly owned subsidiaries of Williams, Transco and NWP do not have separate audit committees. The Williams Audit Committee is responsible for the appointment, compensation, retention, and oversight of Ernst & Young LLP (EY) as such appointment relates to Transco, NWP, and Williams’ other subsidiaries. The Williams Audit Committee is responsible for overseeing the determination of fees associated with EY’s audit of Transco and NWP’s financial statements. The Williams Audit Committee has established a policy regarding pre-approval of all audit and non-audit services provided by EY to Williams and its subsidiaries. On an ongoing basis, management presents specific projects and categories of service, including projects and categories of service relating to Transco and NWP, to the Williams Audit Committee to request advance approval. The Williams Audit Committee reviews those requests and advises management if the Williams Audit Committee approves the engagement of EY. On a periodic basis, management reports to the Williams Audit Committee regarding the actual spending for such projects and services compared to the approved amounts. The Williams Audit Committee may also delegate the authority to pre-approve audit and permitted non-audit services, excluding services related to internal control over financial reporting, to a subcommittee of one or more committee members, provided that any such pre-approvals are reported on at a subsequent Williams Audit Committee meeting.
