Ladies and Gentlemen:

We have acted as counsel to Vanguard  Montgomery Funds (the "Acquiring  Trust"),

connection  with its  acquisition of all of the assets and liabilities of Landus
Rosenberg U.S.  Large/Mid  Capitalization  Long/Short Equity Fund (the "Acquired
Fund"),  a series of DWS Funds Trust (the  "Acquired  Trust"),  in exchange  for
Institutional  and Investor  shares of  beneficial  interests  ("Acquiring  Fund
Shares"),   pursuant  to  the   Agreement  and  Plan  of   Reorganization   (the
"Agreement"),  by and between the  Acquiring  Trust,  on behalf of the Acquiring
Fund; the Acquired  Trust,  on behalf of the Acquired Fund; The Vanguard  Group,
Inc., a Pennsylvania corporation,  (with respect to the provisions of Paragraphs
9.2 and 9.4  only);  Charles  Schwab  Investment  Management,  Inc.,  a Delaware

only); and AXA Rosenberg Investment Management LLC, a Delaware limited liability
company (with respect to the provisions of Paragraphs 9.2 and 9.3 only).

We have examined the  Acquiring  Trust's  draft  Registration  Statement on Form
N-1A,  the  Acquiring  Trust's  draft  registration  Statement on Form N-14 (the
"Registration  Statement"),  the Acquiring  Trust's Agreement and Declaration of

adopted by the Acquiring  Trust's Board of Trustees with respect to the issuance
of the  Acquiring  Fund Shares  pursuant to the  Agreement,  and other  records,
documents  and papers  that we have  deemed  necessary  for the  purpose of this
opinion.  We have examined such other statutes and authorities as we have deemed
necessary to form a basis for the opinions hereinafter  expressed.  We have also

to be issued and delivered to  shareholders of the Acquired Fund pursuant to the
terms of the Agreement,  upon issuance,  will be validly issued,  fully paid and
non-assessable.

We are  members  of the Bar of the State of New York only and do not opine as to
the laws of any  jurisdiction  other  than the laws of the State of New York and

This opinion is furnished by us as counsel to the Acquiring Trust, is solely for
the benefit of the Acquiring  Trust and the Acquiring Fund and may not be relied
upon for any other  purpose  or by any other  person.  We hereby  consent to the
filing of this opinion as an exhibit to the  Registration  Statement  and to the
