OFI Tremont Core Diversified Hedge Fund
6803 South Tucson Way
Englewood, Colorado 80112


Ladies and Gentlemen:

This opinion is being furnished to OFI Tremont Core Diversified Hedge Fund, a
Massachusetts business trust (the "Fund"), in connection with the
Registration Statement on Form N-2 (the "Registration Statement") under the
Securities Act of 1933, as amended (the "1933 Act"), and the Investment
Company Act of 1940, as amended, filed by the Fund.  As counsel for the Fund,
we have examined such statutes, regulations corporate records and other
documents and reviewed such questions of law that we deemed necessary or
appropriate for the purposes of this opinion.

As to matters of Massachusetts law contained in this opinion, we have relied
upon the opinion of Kushner, Sanders & Krone LLP, dated December 16, 2002.

Based upon the foregoing, we are of the opinion that the shares of beneficial
interest to be issued as described in the Registration Statement have been
duly authorized for issuance and, when issued and delivered by the Fund in
exchange for the consideration stated in the Registration Statement, will be
validly issued, fully paid and nonassessable (except for the potential
liability of shareholders described in the Fund's Statement of Additional
Information incorporated into the Registration Statement, under the caption
"Liability of Shareholders - Duty of Care").

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us in the Registration
Statement.  We do not thereby admit that we are within the category of
persons whose consent is required under Section 7 of the 1933 act or the
rules and regulations of the Securities and Exchange Commission thereunder.

Sincerely,



Mayer, Brown, Rowe & Maw
