REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


Trustees and Shareholders
Oppenheimer Core Bond Fund

In planning and performing our audit of the financial statements of Oppenheimer
Core Bond Fund (formerly the Oppenheimer Bond Fund, the "Fund") for the year
ended December 31, 2004 (on which we have issued our report dated February 11,
2005), we considered its internal control, including control activities 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, and not to provide assurance on the Fund's
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
controls. 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 accounting principles generally accepted
in the United States of America. Those controls include the safeguarding of
assets against unauthorized acquisition, use, or disposition.

Because of inherent limitations in any internal control, misstatements due to
error or fraud may occur and not be detected. Also, projections of any
evaluation of internal control to future periods are subject to the risk that
the internal control may become inadequate because of changes in conditions or
that the degree of compliance with policies or procedures may deteriorate.

Our consideration of the Fund's internal control would not necessarily disclose
all matters in the internal control 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 one or
more of the internal control components does not reduce to a relatively low
level the risk that misstatements caused by error or fraud 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
Fund's internal control and its operation, including controls for safeguarding
securities, that we consider to be material weaknesses as defined above as of
December 31, 2004.

This report is intended solely for the information and use of management, the
Trustees and Shareholders of Oppenheimer Core Bond Fund, and the Securities and
Exchange Commission and is not intended to be and should not be used by anyone
other than these specified parties.

ROCSOP

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 December 31, 2004. Net assets of
the Fund were unaffected by the reclassifications.

EX-99.77E LEGAL

LITIGATION

A consolidated amended complaint has been filed as putative derivative and class
actions against the Manager, OFS and the Distributor (collectively, the
"Oppenheimer defendants"), as well as 51 of the Oppenheimer funds (as "Nominal
Defendants") including the Fund, 31 present and former Directors or Trustees and
9 present and former officers of the funds. This complaint, filed in the U.S.
District Court for the Southern District of New York on January 10, 2005,
consolidates into a single action and amends six individual previously-filed
putative derivative and class action complaints. Like those prior complaints,
the complaint alleges that the Manager charged excessive fees for distribution
and other costs, improperly used assets of the funds in the form of directed
brokerage commissions and 12b-1 fees to pay brokers to promote sales of the
funds, and failed to properly disclose the use of assets of the funds to make
those payments in violation of the Investment Company Act of 1940 and the
Investment Advisers Act of 1940. Also, like those prior complaints, the
complaint further alleges that by permitting and/or participating in those
actions, the Directors/Trustees and the Officers breached their fiduciary duties
to shareholders of the funds under the Investment Company Act of 1940 and at
common law. The complaint seeks unspecified compensatory and punitive damages,
rescission of the funds' investment advisory agreements, an accounting of all
fees paid, and an award of attorneys' fees and litigation expenses.

      The Oppenheimer defendants believe that the allegations contained in the
Complaints are without merit and that they, the funds named as Nominal
Defendants, and the Directors/Trustees of those funds have meritorious defenses
against the claims asserted. The Oppenheimer defendants intend to defend these
lawsuits vigorously and to contest any claimed liability, and they have retained
legal counsel to defend such suits. The Oppenheimer defendants believe that it
is premature to render any opinion as to the likelihood of an outcome
unfavorable to them and that no estimate can yet be made with any degree of
certainty as to the amount or range of any potential loss.

                              AMENDED AND RESTATED
                          INVESTMENT ADVISORY AGREEMENT


         AGREEMENT made the 1st day of January, 2005, by and between OPPENHEIMER

MANAGEMENT CORPORATIONS (hereinafter referred to as "OFI").

         WHEREAS, the Trust is an open-end, diversified series management
investment company registered as such with the Securities and Exchange

(the "Investment Company Act"), and OFI is an investment adviser registered as
such with the Commission under the Investment Advisers Act of 1940;

         WHEREAS, the Trust desires that OFI shall act as its investment adviser
pursuant to this Agreement, which amends and restates the Investment Advisory
Agreement dated July 10, 1995, as amended on February 26, 2002, by and between
the Trust and OFI; and

         WHEREAS, OPPENHEIMER BOND FUND (the "Fund") is a series of the Trust
having a separate portfolio, investment policies and investment restrictions;

         NOW, THEREFORE, in consideration of the mutual promises and covenants
hereinafter set forth, it is agreed by and between the parties, as follows:

1. General Provision.

(a) The Trust hereby employs OFI and OFI hereby undertakes to act as the
investment adviser of the Fund and to perform for the Fund such other duties and
functions as are hereinafter set forth. OFI shall, in all matters, give to the
Fund and the Trust's Board of Trustees the benefit of its best judgment, effort,

efforts to enable the Fund to conform to (i) the provisions of the Investment
Company Act and any rules or regulations thereunder; (ii) any other applicable
provisions of state or federal law; (iii) the provisions of the Declaration of
Trust and By-Laws of the Trust as amended from time to time; (iv) policies and

time to time. The appropriate officers and employees of OFI shall be available
upon reasonable notice for consultation with any of the Trustees and officers of
the Trust with respect to any matters dealing with the business and affairs of
the Trust including the valuation of portfolio securities of the Fund which are

(b) At its option, OFI may appoint a sub-adviser (which may be affiliated with
OFI) to perform all or such responsibilities of OFI under this Agreement as
shall be delegated by OFI to such subadviser provided, however, that the
appointment of any subadviser and the assumption by such subadviser of any
responsibilities of OFI shall be subject to the approval of the Board of
Trustees of the Trust, including the vote of the majority of the Trustees of the
Trust who are not parties to this Agreement or "interested persons" (as defined
in the Investment Company Act) ofany such person, cast in person at a meeting
called for the purpose of voting on such approval, and, to the extent necessary,
the shareholders of the Fund. OFI agrees to give the Trust prompt written notice
of the termination of, or any notice to terminate, any subadviser agreement.

2. Investment Management.

Trustees, (i) supervise and monitor continuously the investment program of the
Fund and the composition of its portfolio and determine what securities shall be
purchased or sold by the Fund; (ii) subject to subsection (i) hereof, regularly
provide investment advice and recommendations to the Fund with respect to its
investments, investment policies and the purchase and sale of securities; and
(iii) arrange, subject to the provisions of paragraph 7 hereof, for the purchase
of securities and other investments for the Fund and the sale of securities and
other investments held in the Fund's portfolio.

(b) Provided that the Trust shall not be required to pay any compensation other
than as provided by the terms of this Agreement and subject to the provisions of
paragraph 7 hereof, OFI may obtain investment information, research or
assistance from any other person, firm or corporation to supplement, update or
otherwise improve its investment management services.

(c) Provided that nothing herein shall be deemed to protect OFI from willful
misfeasance, bad faith or gross negligence in the performance of its duties, or
reckless disregard of its obligations and duties under this Agreement, OFI shall
not be liable for any loss sustained by reason of good faith errors or omissions
in connection with any matters to which this Agreement relates.

(d) Nothing in this Agreement shall prevent OFI or any officer thereof from
acting as investment adviser for any other person, firm or corporation and shall
not in any way limit or restrict OFI or any of its directors, officers,
stockholders or employees from buying, selling or trading any securities for its
or their own account or for the account of others for whom it or they may be
acting, provided that such activities will not adversely affect or otherwise
impair the performance by OFI of its duties and obligations under this
Agreement.

3. Other Duties of OFI.

         OFI shall, at its own expense, provide and supervise the activities of
all administrative and clerical personnel as shall be required to provide
effective corporate administration for the Fund, including the compilation and
maintenance of such records with respect to its operations as may reasonably be
required; the preparation and filing of such reports with respect thereto as
shall be required by the Commission; composition of periodic reports with

expense, also provide the Trust with adequate office space, facilities and
equipment. OFI shall, at its own expense, provide such officers for the Trust as
the Trust's Board may request.

4.       Allocation of Expenses.

         All other costs and expenses of the Fund not expressly assumed by OFI
under this Agreement, by a sub-adviser under any Sub-Advisory Agreement or to be
paid by the Distributor of the shares of the Fund, shall be paid by the Trust,
including, but not limited to: (i) interest and taxes; (ii) brokerage

to its operations; (iv) compensation and expenses of the Trust's trustees other
than those affiliated with OFI; (v) legal and audit expenses; (vi) custodian and
transfer agent fees and expenses; (vii) expenses incident to the redemption of
its shares; (viii) expenses incident to the issuance of its shares against

officers or employees of OFI or any entity controlling, controlled by or under
common control with OFI who may also serve as officers, trustees or employees of
the Fund shall not receive any compensation from the Fund for their services.
The expenses with respect to any two or more series of the Trust shall be
allocated in proportion to the net assets of the respective series except where
allocations of direct expenses can be made.

5.       Compensation of OFI.

         The Trust agrees to pay OFI and OFI agrees to accept as full
compensation for the performance of all functions and duties to be performed
pursuant to the provisions hereof, a fee computed on the aggregate net asset
value of the Fund as of the close of each business day and payable monthly at
the following annual rate:

         0.60% of the first $200 million of average annual net assets; 0.57% of
         the next $200 million; 0.54% of the next $200 million; 0.51% of the
         next $200 million; 0.45% of the next $200 million; and 0.35% of average
         annual net assets in excess of $1 billion.

6.       Use of Name "Oppenheimer."

         OFI hereby grants to the Trust a royalty-free, non-exclusive license to
use the name "Oppenheimer" in the name of the Trust and the Fund for the
duration of this Agreement and any extensions or renewals thereof.

         To the extent necessary to protect OFI's rights to the name
"Oppenheimer" under applicable law, such license shall allow OFI to inspect and,
subject to control by the Trust's Board, control the nature and quality of
services offered by the Fund under such name. Such license may, upon termination
of this Agreement, be terminated by OFI, in which event the Trust shall promptly
take whatever action may be necessary to change its name and the name of the
Fund and discontinue any further use of the name "Oppenheimer" in the name of
the Trust and the Fund or otherwise. The name "Oppenheimer" may be used by OFI
in connection with any of its activities, or licensed by OFI to any other party.

7. Portfolio Transactions and Brokerage.

(a) OFI is authorized, in arranging the purchase and sale of the Fund's
portfolio securities, to employ or deal with such members of securities or
commodities exchanges, brokers or dealers (hereinafter "broker-dealers"),
including "affiliated" broker-dealers (as that term is defined in the Investment
Company Act), as may, in its best judgment, implement the policy of the Fund to
obtain, at reasonable expense, the "best execution" (prompt and reliable
execution at the most favorable security price obtainable) of the Fund's
portfolio transactions as well as to obtain, consistent with the provisions of
subparagraph (c) of this paragraph 7, the benefit of such investment information
or research as will be of significant assistance to the performance by OFI of
its investment management functions.

(b) OFI shall select broker-dealers to effect the Fund's portfolio transactions
on the basis of its estimate of their ability to obtain best execution of
particular and related portfolio transactions. The abilities of a broker-dealer
to obtain best execution of particular portfolio transaction(s) will be judged
by OFI on the basis of all relevant factors and considerations including,
insofar as feasible, the execution capabilities required by the transaction or
transactions; the ability and willingness of the broker-dealer to facilitate the
Fund's portfolio transactions by participating therein for its own account; the
importance to the Fund of speed, efficiency or confidentiality; the
broker-dealer's apparent familiarity with sources from or to whom particular
securities might be purchased or sold; as well as any other matters relevant to
the selection of a broker-dealer for particular and related transactions of the
Fund.

(c) OFI shall have discretion, in the interests of the Fund, to allocate
brokerage on the Fund's portfolio transactions to broker-dealers, other than
affiliated broker-dealers, qualified to obtain best execution of such
transactions who provide brokerage and/or research services (as such services
are defined in Section 28(e)(3) of the Securities Exchange Act of 1934) for the
Fund and/or other accounts for which OFI or its affiliates exercise "investment
discretion" (as that term is defined in Section 3(a)(35) of the Securities
Exchange Act of 1934) and to cause the Fund to pay such broker-dealers a
commission for effecting a portfolio transaction for the Fund that is in excess
of the amount of commission another broker-dealer adequately qualified to effect
such transaction would have charged for effecting that transaction, if OFI
determines, in good faith, that such commission is reasonable in relation to the
value of the brokerage and/or research services provided by such broker-dealer,
viewed in terms of either that particular transaction or the overall
responsibilities of OFI or its affiliates with respect to the accounts as to
which they exercise investment discretion. In reaching such determination, OFI
will not be required to place or attempt to place a specific dollar value on the
brokerage and/or research services provided or being provided by such
broker-dealer. In demonstrating that such determinations were made in good
faith, OFI shall be prepared to show that all commissions were allocated for
purposes contemplated by this Agreement and that the total commissions paid by
the Fund over a representative period selected by the Trustees were reasonable
in relation to the benefits to the Fund.

(d) OFI shall have no duty or obligation to seek advance competitive bidding for
the most favorable commission rate applicable to any particular portfolio
transactions or to select any broker-dealer on the basis of its purported or
"posted" commission rate but will, to the best of its ability, endeavor to be
aware of the current level of the charges of eligible broker-dealers and to
minimize the expense incurred by the Fund for effecting its portfolio
transactions to the extent consistent with the interests and policies of the
Fund as established by the determinations of the Board of Trustees and the
provisions of this paragraph 7.

(e) The Trust recognizes that an affiliated broker-dealer: (i) may act as one of
the Fund's regular brokers for the Fund so long as it is lawful for it so to
act; (ii) may be a major recipient of brokerage commissions paid by the
brokerage commissions paid by the Fund; and (iii) may effect portfolio
transactions for the Fund only if the commissions, fees or other remuneration
received or to be received by it are determined in accordance with procedures
contemplated by any rule, regulation or order adopted under the Investment
Company Act for determining the permissible level of such commissions.

8. Duration.

         This Agreement will take effect on the date first set forth above.
Unless earlier terminated pursuant to paragraph 9 hereof, this Agreement shall
remain in effect from year to year, so long as such continuance shall be
approved at least annually by the Trust's Board of Trustees, including the vote
of the majority of the Trustees of the Trust who are not parties to this
Agreement or "interested persons" (as defined in the Investment Company Act) of
any such party, cast in person at a meeting called for the purpose of voting on
such approval, or by the holders of a "majority" (as defined in the Investment
Company Act) of the outstanding voting securities of the Fund and by such a vote
of the Trust's Board of Trustees.

9.       Termination.

         This Agreement may be terminated (i) by OFI at any time without penalty
upon sixty days' written notice to the Trust (which notice may be waived by the
Trust); or (ii) by the Trust at any time without penalty upon sixty days'
written notice to OFI (which notice may be waived by OFI) provided that such
termination by the Trust shall be directed or approved by the vote of a majority
of all of the Trustees of the Trust then in office or by the vote of the holders
of a "majority" of the outstanding voting securities of the Fund (as defined in
the Investment Company Act).

10.      Assignment or Amendment.

         This Agreement may not be amended or the rights of OFI hereunder sold,
transferred, pledged or otherwise in any manner encumbered without the
affirmative vote or written consent of the holders of the "majority" of the
outstanding voting securities of the Fund. This Agreement shall automatically
and immediately terminate in the event of its "assignment" (as defined in the
Investment Company Act).

11.      Disclaimer of Shareholder or Trustee Liability.

         OFI understands and agrees that the obligations of the Trust or the
Fund under this Agreement are not binding upon any trustee or shareholder of the
Trust or the Fund personally, but bind only the Trust and the Trust's property.
OFI represents that it has notice of the provisions of the Declaration of Trust
of the Trust disclaiming shareholder or trustee liability for acts or
obligations of the Trust.

12.      Definitions.

         The terms and provisions of the Agreement shall be interpreted and
defined in a manner consistent with the provisions and definitions contained in
the Investment Company Act.
