         Re:   Units of Beneficial Interest of Nations Institutional Reserves

Ladies/Gentlemen:

         We refer to the Registration Statement on Form N-14 (the "Registration
Statement") of Nations Institutional Reserves ("Reserves") relating to the
registration of an indefinite number of units of beneficial interest (the
"Shares"), of certain Funds of Reserves (the "Funds").

         We have been requested by Reserves to furnish this opinion as Exhibit
11 to the Registration Statement.

         We have examined documents relating to the organization of Reserves and
the authorization and issuance of the Shares. We have also made such inquiries
of Reserves and examined such questions of law as we have deemed necessary for
the purpose of rendering the opinion set forth herein. We have assumed the
genuineness of all signatures and the authenticity of all items submitted to us
as originals and the conformity with originals of all items submitted to us as
copies.

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

         The issuance of the Shares by Reserves has been duly and validly
authorized by all appropriate action and, assuming delivery in accordance with
the description set forth in the Combined Proxy Statement/Prospectus included in
the Registration Statement, the Shares will be legally issued, fully paid and
nonassessable by Reserves.
