Sector Fund, each a series of the Trust ("Shares"), under the Securities Act of
1933, as amended ("1933 Act").

      You have requested our opinion as to the matters set forth below in
connection with the filing of the Post-Effective Amendment. For purposes of
rendering that opinion, we have examined the Post-Effective Amendment, the
Trust's Certificate of Trust, Declaration of Trust and By-laws, and the actions
of the Trust that provide for the issuance of the Shares, and we have made such
other investigations as we have deemed appropriate. We have examined and relied
upon certificates of public officials and, as to certain matters of fact that
are material to our opinion; we have also relied on a certificate of an officer
of the Trust. In rendering our opinion, we also have made the assumptions that
are customary in opinion letters of this kind. We have not verified any of those
assumptions.



      Our opinion, as set forth herein, is based on the facts in existence and
the laws in effect on the date hereof and is limited to the federal laws of the
United States of America and the laws of the State of Delaware that, in our
experience, generally are applicable to the issuance of shares by entities such
as the Trust. We express no opinion with respect to any other laws.

      Based upon and subject to the foregoing, we are of the opinion that:

      1.    The Shares to be issued pursuant to the Post-Effective Amendment
            have been duly authorized for issuance by the Trust; and

      2.    When issued and paid for upon the terms provided in the
            Post-Effective Amendment, the Shares to be issued pursuant to the
            Post-Effective Amendment will be validly issued, fully paid, and
            nonassessable.

      The opinion expressed in paragraph 2 above is subject to the effect of
bankruptcy, insolvency, fraudulent transfers, reorganization, receivership
moratorium, and other laws affecting the rights of creditors generally and to
general principles of equity (whether applied by a court of law or equity).

      This opinion is rendered solely in connection with the filing of the
Post-Effective Amendment and supersedes any previous opinions of this firm in
connection with the issuance of Shares. We hereby consent to the filing of this
opinion with the SEC in connection with the Post-Effective Amendment and to the
reference to this firm in the statement of additional information that is being
filed as part of the Post-Effective Amendment. In giving our consent we do not
thereby admit that we are in the category of persons whose consent is required
under Section 7 of the 1933 Act or the rules and regulations of the SEC
thereunder.

                             Very truly yours,


                             /s/ Kirkpatrick & Lockhart Preston Gates Ellis LLP
