         RE:    Plan of Reorganization  for Combining the IMG Mutual Funds, Inc.
                and the Core  Stock  Fund  (the  "Stock  Fund"),  (the  Acquired
                Portfolio")  into the IMG Mutual  Funds,  Inc.,  and its Vintage
                Equity Fund (the "Surviving Fund")

Dear Sirs:

         We have been asked to give our opinion relating to the  above-described
transaction   (the   "Reorganization"),   as  to  certain   Federal  income  tax
consequences  of  consummating  the  transactions  contemplated  in the  Plan of
Reorganization (the "Plan").

BACKGROUND

   
         IMG Mutual Funds, Inc. ("IMG") is a Maryland corporation  consisting of
multiple investment  portfolios,  including,  the Acquired Portfolio  identified
above (the  "Transferor  Fund") and the Surviving  Fund  identified  above.  The
Transferor  Fund  and the  Surviving  Fund  are  sometimes  referred  to  herein
collectively  as "Funds."  IMG, as well as each of the  "Funds",  is  registered
under the Investment Company Act of 1940, as amended,  as an open-end investment
company of the management type.
    

         It is proposed that all the assets and  liabilities  of the  Transferor
Fund be transferred to the Surviving Fund. As  consideration  for such transfer,
the  Surviving  Fund is  issuing  to the  Transferor  Fund a number  of full and
fractional  shares of common stock in the Surviving  Fund equal to the net asset
value  of the  shares  outstanding  of the  respective  Transferor  Fund  at the
Effective Time of the Reorganization.

         Immediately after the transfer, the Surviving Fund shares issued to the
Transferor Fund are to be distributed to the shareholders of the Transferor Fund
in  liquidation of the  Transferor  Fund,  and the  Transferor  Fund is to cease
operations.  Each  Transferor  Fund  shareholder  is  receiving  shares  of  the
Surviving  Fund  in  proportion  to  the  shareholding  in the  Transferor  Fund
immediately before the Reorganization.  The outstanding shares of the Transferor
Fund are to be canceled, and the Transferor Fund is to be terminated.

ASSUMPTIONS

         For purposes of this opinion, we have made several assumptions:

         First,  that each of the Funds is qualified as a "regulated  investment
company"  under Part I of Subchapter M of Subtitle A, Chapter 1, of the Internal
Revenue Code of 1986, as amended (the "Code") and also meet the  diversification
requirements  of Code  ss.368(a)(2)(E)(ii),  for its most recently  ended fiscal
year and will continue to so qualify for its current fiscal year;

         Second,  that the Surviving  Fund is acquiring at least 90% of the fair
market  value of the net assets and at least 70% of the fair market value of the
gross assets held by the Transferor Fund  immediately  prior to the transaction,
treating any assets used to make other than regular and normal  distributions or
redemptions as unacquired assets;

         Third,  that the  shareholders  of the Transferor  Fund have no plan or
intention  to dispose of a number of shares of the  Surviving  Fund  received by
them as a result of the  transaction  which would  result in their owning in the
aggregate  shares of the Surviving  Fund having a fair market value that is less
than 50% of the fair market value of the  Transferor  Fund's shares  outstanding
immediately  before the  transaction  (including  any  Transferor  Fund's shares
redeemed in anticipation of the transaction);

         Fourth,  that the Surviving  Fund has no plan or intention to reacquire
any of its  shares  issued in the  transaction,  except for  redemptions  in the
ordinary course of business as a regulated investment company;

         Fifth,  that the  Surviving  Fund has no plan or  intention  to sell or
otherwise to dispose of any of the assets of the Transferor Fund acquired in the
transaction, except for dispositions made in the ordinary course of business;

         Sixth,  that the  liabilities  of the  Transferor  Fund  assumed by the
Surviving  Fund and the  liabilities  to which  the  transferred  assets  of the
Transferor Fund are subject were incurred by the Transferor Fund in the ordinary
course of business;

         Seventh,  that the transaction serves a business purpose or purposes of
the Funds and that  following the  transaction  the Surviving Fund will continue
the historic business of the Transferor Fund or use a significant portion of the
Transferor Fund's historic business assets in a business;

         Eighth, that there is no intercorporate  indebtedness  existing between
the Surviving Fund and the Transferor Fund that was issued,  acquired or will be
settled at a discount;

         Ninth,  that the Surviving  Fund does not own,  directly or indirectly,
nor have they owned  during the past five  years,  directly or  indirectly,  any
stock of the Transferor Fund;

         Tenth,  that the  Transferor  Fund is not under the  jurisdiction  of a
court in a case under  Title 11 of the  United  States  Code or a  receivership,
foreclosure or similar proceeding in any Federal or State court; and

         Eleventh,  that  the Plan  substantially  in the  form  included  as an
exhibit to the registration  statement of the Surviving Fund, on Form N-14 under
the Securities Act of 1933 (the  "Registration  Statement")  has been or will be
duly authorized by the Surviving Fund.

         The opinions set forth below are subject to the approval of the Plan by
the shareholders of the Transferor Fund, to the proper  submission and filing of
appropriate  documents  with  the  appropriate  government  agencies  and to the
satisfaction of the terms and conditions set forth in the Plan.

CONCLUSIONS

         Based upon the Code,  applicable  Treasury  Department  regulations  in
effect as of the date hereof, current published  administrative positions of the
Internal  Revenue  Service  contained  in revenue  rulings and  procedures,  and
judicial  decisions,  and upon the information,  representations and assumptions
contained  herein and in the documents  provided to us by you, it is our opinion
for Federal income tax purposes that:

                    (i) the transfer of all of the assets and liabilities of the
         Transferor  Fund to the  Surviving  Fund in exchange  for shares of the
         Surviving Fund and  distribution to shareholders of the Transferor Fund
         of the  shares  the  shares  of the  Surviving  Fund  so  received,  as
         described  in the Plan,  will  constitute a  reorganization  within the
         meaning of Code section 368(a)(1)(C) or 368(a)(1)(D);

                   (ii) in accordance with sections 361(a), 361(c)(1) and 357(a)
         of the Code, no gain or loss will be recognized by any Transferor  Fund
         as a result of such transactions;

                  (iii) in accordance with section 1032(a) of the Code,  no gain
         or loss will be recognized by the Surviving  Fund  as  a result of such
         transactions;

                   (iv) in  accordance  with section  354(a)(1) of the Code,  no
         gain or loss will be recognized by the shareholders of any of the Funds
         on the  distribution  to them by the  Transferor  Fund of shares of the
         Surviving  Fund in exchange  for their shares of such  Transferor  Fund
         (but  shareholders  of  an  Acquired  Fund  subject  to  taxation  will
         recognize  income  upon  receipt  of any net  investment  income or net
         capital gains of such Acquired  Funds which are  distributed to them by
         such Acquired Fund prior to the closing date of its Reorganization);

                    (v) in accordance  with section  358(a)(1) of the Code,  the
         basis of the Surviving  Fund shares  received by a  shareholder  of the
         Transferor  Fund  will be the same as the  basis  of the  shareholder's
         Transferor Fund shares immediately before the transactions;

                   (vi) in accordance with section 362(b) of the Code, the basis
         to the  Surviving  Fund of the assets of the  Transferor  Fund received
         pursuant  to the  transactions  will be the same as the  basis of those
         assets in the hands of such  Transferor  Fund  immediately  before  the
         transactions;

                  (vii) in  accordance  with  section  1223(1)  of the  Code,  a
         shareholder's   holding  period  for  Surviving  Fund  shares  will  be
         determined  by  including  the  period for which the  shareholder  held
         Transferor   Fund  shares   exchanged   therefor,   provided  that  the
         shareholder held such Transferor Fund shares as a capital asset; and

                 (viii) in  accordance  with  section  1223(2) of the Code,  the
         Surviving Fund's holding period with respect to any asset acquired from
         the  Transferor  Fund will  include the period for which such asset was
         held by such Transferor Fund; and

                   (ix) the  Surviving  Fund will  succeed and take into account
         the  earnings  and profits or  deficits in earnings  and profits of the
         corresponding Acquired Fund as of the closing of the Reorganization.

         We express no opinion  relating to any Federal income tax matter except
on the basis of the documents and  assumptions  described  above. In issuing our
opinion,  we have relied solely upon existing  provisions of the Code,  existing
and proposed  regulations  thereunder,  and current  administrative  rulings and
court  decisions.  Such  laws,  regulations,  administrative  rulings  and court
decisions  are subject to change at any time.  Any such change  could affect the
validity of the opinion set forth above.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration  Statement  and to the  references  to our firm  under the  caption
"Federal  Income Tax  Consequences"  in the Combined Proxy  Statement/Prospectus
constituting a part of the Registration Statement.

                                Very truly yours,

                                /s/ Cline, Williams, Wright,
