To the Board of Trustees of
Oppenheimer Intermediate Municipal Fund:

In planning and performing our audit of the financial statements of Oppenheimer
Intermediate Municipal Fund (Fund) for the year ended September 30, 1997 (on
which we have issued our report dated October 21, 1997), we considered its
internal control, including controls over safeguarding securities, in order to
determine our auditing procedures for the purpose of expressing our opinion on
the financial statements and to comply with the requirements of Form N-SAR, not
to provide assurance on internal control.

The management of the Fund is responsible for establishing and maintaining
internal control. In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and related costs of
control. Generally, controls that are relevant to an audit pertain to the
entity's objective of preparing financial statements for external purposes that
are fairly presented in conformity with generally accepted accounting
principles. Those controls include the safeguarding of assets against
unauthorized acquisition, use, or disposition.

Because of inherent limitations in internal control, errors or irregularities
may occur and not be detected. Also, projection of any evaluation of internal
control to future periods is subject to the risk that it may become inadequate
because of changes in conditions or that the effectiveness of the design and
operation may deteriorate.

Our consideration of the internal control structure would not necessarily
disclose all matters in internal control structure that might be material
weaknesses under standards established by the American Institute of Certified
Public Accountants. A material weakness is a condition in which the design or
operation of any specific internal control component does not reduce to a
relatively low level the risk that errors or irregularities in amounts that
would be material in relation to the financial statements being audited may
occur and not be detected within a timely period by employees in the normal
course of performing their assigned functions. However, we noted no matters
involving internal control, including controls over safeguarding securities,
that we consider to be material weaknesses as defined above as of September 30,
1997.

This report is intended solely for the information and use of management, the
Board of Trustees and the Securities and Exchange Commission.

Yours truly,


/s/Deloitte & Touche LLP

The Fund adjusts the classification of distributions to shareholders to reflect
the differences between financial statement amounts and distributions determined
in accordance with income tax regulations. Accordingly, during the period ended
September 30, 1997, amounts have been reclassified to reflect a decrease in
undistributed net investment income of $173,785, a decrease in accumulated net
realized loss on investments of $547,316, and a decrease in paid-in capital of
$373,531.

To the Board of Trustees of
Oppenheimer Insured Municipal Fund:

In planning and performing our audit of the financial statements of Oppenheimer
Insured Municipal Fund (Fund) for the year ended September 30, 1997 (on which we
have issued our report dated October 21, 1997), we considered its internal
control, including controls over safeguarding securities, in order to determine
our auditing procedures for the purpose of expressing our opinion on the
financial statements and to comply with the requirements of Form N-SAR, not to
provide assurance on internal control.

The management of the Fund is responsible for establishing and maintaining
internal control. In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and related costs of
control. Generally, controls that are relevant to an audit pertain to the
entity's objective of preparing financial statements for external purposes that
are fairly presented in conformity with generally accepted accounting
principles. Those controls include the safeguarding of assets against
unauthorized acquisition, use, or disposition. Because of inherent limitations
in internal control, errors or irregularities may occur and not be detected.
Also, projection of any evaluation of internal control to future periods is
subject to the risk that it may become inadequate because of changes in
conditions or that the effectiveness of the design and operation may
deteriorate.

Our consideration of the internal control structure would not necessarily
disclose all matters in internal control structure that might be material
weaknesses under standards established by the American Institute of Certified
Public Accountants. A material weakness is a condition in which the design or
operation of any specific internal control component does not reduce to a
relatively low level the risk that errors or irregularities in amounts that
would be material in relation to the financial statements being audited may
occur and not be detected within a timely period by employees in the normal
course of performing their assigned functions. However, we noted no matters
involving internal control, including controls over safeguarding securities,
that we consider to be material weaknesses as defined above as of September 30,
1997.

This report is intended solely for the information and use of management, the
Board of Trustees and the Securities and Exchange Commission.

Yours truly,


/s/Deloitte & Touche LLP

The Fund adjusts the classification of distributions to shareholders to reflect
the differences between financial statement amounts and distributions determined
in accordance with income tax regulations. Accordingly, during the year
September 30, 1997, amounts have been reclassified to reflect a decrease in
undistributed net investment income of $355,343, an increase in accumulated net
realized gain on investments of $651,828, and a decrease in paid-in capital of
$296,485.
