To the Board of Directors of
Oppenheimer Main Street Income and Growth Fund:
In planning and performing our audit of the financial statements of Oppenheimer
Main Street Income and Growth Fund (the Fund) for the year ended June 30, 1996
(on which we have issued our report dated July 22, 1996), we considered its
internal control structure, including procedures for 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 the internal control structure.
The management of the Fund is responsible for establishing and maintaining an
internal control structure. In fulfilling this responsibility, estimates and
judgments by management are required to assess the expected benefits and related
costs of internal control structure policies and procedures. Two of the
objectives of an internal control structure are to provide management with
reasonable, but not absolute, assurance that assets are safeguarded against loss
from unauthorized use or disposition and that transactions are executed in
accordance with management's authorization and recorded properly to permit
preparation of financial statements in conformity with generally accepted
accounting principles.
Because of inherent limitations in any internal control structure, errors or
irregularities may occur and not be detected. Also, projection of any evaluation
of the structure 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 the 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 the specific internal control structure elements 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 the internal control structure, including procedures for safeguarding
securities, that we consider to be material weaknesses as defined above as of
June 30, 1996.
This report is intended solely for the information and use of management, the
Board of Directors and the Securities and Exchange Commission.

During the year ended June 30, 1996, the Fund changed the classification of
distributions to shareholders to better disclose the differences between
financial statement amounts and distributions determined in accordance with
income tax regulations. Accordingly, during the year ended June 30, 1996,
amounts have been reclassified to reflect an increase in undistributed net
investment income of $5,072,430 and a decrease in accumulated net realized gain
on investments of $5,072,430.

To the Board of Directors of
Oppenheimer Main Street California Tax-Exempt Fund:
In planning and performing our audit of the financial statements of Oppenheimer
Main Street California Tax-Exempt Fund (the Fund) for the year ended June 30,
1996 (on which we have issued our report dated July 22, 1996), we considered its
internal control structure, including procedures for 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 the internal control structure.
The management of the Fund is responsible for establishing and maintaining an
internal control structure. In fulfilling this responsibility, estimates and
judgments by management are required to assess the expected benefits and related
costs of internal control structure policies and procedures. Two of the
objectives of an internal control structure are to provide management with
reasonable, but not absolute, assurance that assets are safeguarded against loss
from unauthorized use or disposition and that transactions are executed in
accordance with management's authorization and recorded properly to permit
preparation of financial statements in conformity with generally accepted
accounting principles.
Because of inherent limitations in any internal control structure, errors or
irregularities may occur and not be detected. Also, projection of any evaluation
of the structure 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 the 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 the specific internal control structure elements 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 the internal control structure, including procedures for safeguarding
securities, that we consider to be material weaknesses as defined above as of
June 30, 1996.
