             Report of Independent Registered Public Accounting Firm



The Shareholders and Board of Directors
Oppenheimer Series Funds, Inc.:


In planning and performing our audit of the financial statements of Oppenheimer
Value Fund (one of the portfolios constituting the Oppenheimer Series Funds,
Inc.) (the Fund) as of and for the year ended October 31, 2008, in accordance
with the standards of the Public Company Accounting Oversight Board (United
States), we considered the Fund's internal control over financial reporting,
including controls over safeguarding securities, as a basis for designing our
auditing procedures for the purpose of expressing our opinion on the financial
statements and to comply with the requirements of Form N-SAR, but not for the
purpose of expressing an opinion on the effectiveness of the Fund's internal
control over financial reporting. Accordingly, we express no such opinion.

Management of the Fund is responsible for establishing and maintaining effective
internal control over financial reporting. In fulfilling this responsibility,
estimates and judgments by management are required to assess the expected
benefits and related costs of controls. A company's internal control over
financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted
accounting principles. A company's internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of
records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

A deficiency in internal control over financial reporting exists when the design
or operation of a control does not allow management or employees, in the normal
course of performing their assigned functions, to prevent or detect
misstatements on a timely basis. A material weakness is a deficiency, or a
combination of deficiencies, in internal control over financial reporting, such
that there is a reasonable possibility that a material misstatement of the
Fund's annual or interim financial statements will not be prevented or detected
on a timely basis.

Our consideration of the Fund's internal control over financial reporting was
for the limited purpose described in the first paragraph and would not
necessarily disclose all deficiencies in internal control that might be material
weaknesses under standards established by the Public Company Accounting
Oversight Board (United States). However, we noted no deficiencies in the Fund's
internal control over financial reporting and its operation, including controls
over safeguarding securities, that we consider to be a material weakness as
defined above as of October 31, 2008.

This report is intended solely for the information and use of management and the
Board of Directors of Oppenheimer Series Fund, Inc. and the Securities and
Exchange Commission and is not intended to be and should not be used by anyone
other than these specified parties.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for October 31, 2008. Net assets of the
Fund were unaffected by the reclassifications.
