         Re:  Shares of Beneficial Interest
              AIM Funds Group

Gentlemen:

         We have acted as counsel to AIM Funds Group, a Delaware business trust
(the "Trust"), in connection with (i) the Agreement and Plan of Reorganization
dated September 25, 1997,  between the Trust and AIM Advisor Funds, Inc., a
Maryland corporation ("AAF"), acting on behalf of its portfolio AIM Advisor
Cash Management Fund (the "Cash Management Agreement")  and (ii) the Agreement
and Plan of Reorganization dated September 25, 1997 between the Trust and AAF,
acting on behalf of its portfolio AIM Advisor Income Fund (the "Income Fund
Agreement"), and the consummation of the transactions contemplated therein.

         The Cash Management Agreement contemplates the acquisition of 
substantially all of the assets of AIM Advisor Cash Management Fund by the
Trust, acting on behalf of AIM Money Market Fund, one of its investment
portfolios, in exchange for AIM Cash Reserve Shares of beneficial interest of
AIM Money Market Fund, which shares will be issued directly by the Trust to the
shareholders of AIM Advisor Cash Management Fund (the "Cash Management
Transaction").  Each shareholder of AIM Advisor Cash Management Fund will
receive that number of AIM Cash Reserve Shares of beneficial interest of AIM
Money Market Fund (the "Money Market Shares") representing interests with an
aggregate net asset value equal to the aggregate net asset value of his or her
shares of AIM Advisor Cash Management Fund as of the close of business on the
business day next preceding the closing of the Cash Management Transaction.

         The Income Fund Agreement contemplates the acquisition of 
substantially all of the assets of AIM Advisor Income Fund by the Trust, acting
on behalf of AIM Intermediate Government Fund,

one of its investment portfolios, in exchange for Class A shares and Class C
shares of beneficial interest of AIM Intermediate Government Fund, which shares
will be issued directly by the Trust to the holders of Class A shares and Class
C shares of AIM Advisor Income Fund, respectively (the "Income Fund
Transaction").  Each shareholder of AIM Advisor Income Fund will receive that
number of Class A shares or Class C shares of beneficial interest of AIM
Intermediate Government Fund (the "Intermediate Government Shares")
representing interests with an aggregate net asset value equal to the aggregate
net asset value of his or her Class A shares or Class C shares of AIM Advisor
Income Fund as of the close of business on the business day next preceding the
closing of the Income Fund Transaction.

         The opinion expressed below is based on the assumption that a 
Registration Statement on Form N-14 with respect to the Money Market Shares and
the Intermediate Government Shares will have been filed by the Trust with the
Securities and Exchange Commission and will have become effective before the
Transaction occurs.

         Based on the foregoing, we are of the opinion that the Money Market 
Shares and the Intermediate Government Shares, when issued by the Trust
directly to the shareholders of AIM Cash Reserve Fund and AIM Advisor Income
Fund, respectively, in accordance with the terms and conditions of the Cash
Management Agreement and the Income Fund Agreement, will be legally issued,
fully paid and nonassessable.

         Both the Delaware Business Trust Act and the Trust's Agreement and 
Declaration of Trust, as amended (the "Trust Agreement"), provide that
shareholders of the Trust shall be entitled to the same limitation on personal
liability as is extended under the Delaware General Corporation Law to
stockholders of private corporations for profit.  There is a remote
possibility, however, that, under certain circumstances, shareholders of a
Delaware business trust may be held personally liable for that trust's
obligations to the extent that the courts of another state which does not
recognize such limited liability were to apply the laws of such state to a
controversy involving such obligations.  The Trust Agreement also requires that
notice of such disclaimer of shareholder liability be given in each note, bond,
contract or other undertaking made or issued by the Trustees or Officers of the
Trust.  Such disclaimer is contained in the Cash Management Agreement and the
Income Fund Agreement.  The Trust Agreement also provides for indemnification
out of Trust property for all loss and expense of any shareholder held
personally liable for the obligations of the Trust.  Therefore, the risk of any
shareholder incurring financial loss beyond his

investment due to shareholder liability is limited to circumstances in which
the Trust is unable to meet its obligations and the express disclaimer of
shareholder liabilities is determined not to be effective.

         We consent to the filing of this opinion as Exhibit 11 to the Trust's 
Registration Statement on Form N- 14 and to the references to this firm in such
Registration Statement.

                                        Very truly yours,

                                        /s/ Ballard Spahr Andrews & Ingersoll
