Return of Capital
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 ended
August 31, 1998, amounts have been reclassified to reflect a decrease in
accumulated net investment loss of $1,292,157. Accumulated net realized gain on
investments was decreased by the same amount.

The Board of Trustees and Shareholders of
Oppenheimer Enterprise Fund:
In planning and performing our audit of the financial statements of Oppenheimer
Enterprise Fund for the year ended August 31, 1998, we considered its internal
controls, 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 internal controls.
The management of Oppenheimer Enterprise Fund is responsible for establishing
and maintaining internal controls. In fulfilling this responsibility, estimates
and judgments by management are required to assess the expected benefits and
related costs of internal control policies and procedures. Two of the objectives
of internal controls 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 internal controls, errors or irregularities
may occur and may not be detected. Also, projection of any evaluation of
internal controls to future periods is subject to the risk that they may become
inadequate because of changes in conditions or that the effectiveness of the
design and operation may deteriorate.
Our consideration of internal controls would not necessarily disclose all
matters in internal controls 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 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 internal controls, including
procedures for safeguarding securities, that we considered to be material
weaknesses as defined above as of August 31, 1998.
This report is intended solely for the information and use of management and the
Securities and Exchange Commission and should not be used for any other purpose.
