of its series, The One Group Prime Money Market Fund ("Acquiring Fund") and

one of its series, Pegasus Money Market Fund ("Target Fund"). The Agreement
describes a proposed transaction (the "Transaction") to occur on March 22, 1999,
or such other date as may be decided by the parties (the "Exchange Date"),
pursuant to which Acquiring Fund will acquire substantially all of the assets of
Target Fund in exchange for shares of beneficial interest in Acquiring Fund (the
"Acquiring Fund Shares") and the assumption by Acquiring Fund of all of the
liabilities of Target Fund following which the Acquiring Fund Shares received by
Target Fund will be distributed by Target Fund to its shareholders in
liquidation and termination of Target Fund. This opinion as to certain federal
income tax consequences of the Transaction is furnished to you pursuant to
Sections 9(g) and 10(g) of the Agreement. Capitalized terms not defined herein
are defined in the Agreement.

         Target Fund is a series of the Target Trust which is registered under
the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
management investment company. Shares of Target Fund are redeemable at net asset
value at each shareholder's option. Target Fund has elected to be a regulated

                  within the meaning of Section 368(b) of the Code;

         (ii)     No gain or loss will be recognized by Target Fund upon the
                  transfer of Target Fund's assets to Acquiring Fund in exchange
                  for Acquiring Fund Shares and the assumption by Acquiring Fund
                  of the liabilities of Target Fund, or upon the distribution of
                  Acquiring Fund Shares by Target Fund to its shareholders in
                  liquidation;

         (iii)    No gain or loss will be recognized by the Target Fund
                  shareholders upon the exchange of their Target Fund Shares for

         (iv)     The basis of Acquiring Fund Shares a Target Fund shareholder
                  receives in connection with the Transaction will be the same
                  as the basis of his or her Target Fund Shares exchanged
                  therefor;

         (v)      A Target Fund shareholder's holding period for his or her
                  Acquiring Fund Shares will be determined by including the
                  period for which he or she held the Target Fund Shares
                  exchanged therefor, provided that he or she held such Target
                  Fund Shares as capital assets;

         (vi)     No gain or loss will be recognized by Acquiring Fund upon the
                  receipt of the assets of Target Fund in exchange for Acquiring

                  liabilities of Target Fund;

                  Target Fund transferred to Acquiring Fund in the Transaction
                  will be the same as the basis of such assets in the hands of

Ladies and Gentlemen:

         We have acted as counsel in connection with the Agreement and Plan of
Reorganization dated as of November __, 1998 (the "Agreement"), between The One
Group (the "Acquiring Trust"), a Massachusetts business trust, on behalf of one
of its series, The One Group Cash Management Money Market Fund ("Acquiring
Fund") and Pegasus Fund (the "Target Trust"), a Massachusetts business trust, on
behalf of one of its series, Pegasus Cash Management Money Market Fund ("Target
Fund"). The Agreement describes a proposed transaction (the "Transaction") to
occur on March 22, 1999, or such other date as may be decided by the parties
(the "Exchange Date"), pursuant to which Acquiring Fund will acquire
substantially all of the assets of Target Fund in exchange for shares of
beneficial interest in Acquiring Fund (the "Acquiring Fund Shares") and the
assumption by Acquiring Fund of all of the liabilities of Target Fund following
which the Acquiring Fund Shares received by Target Fund will be distributed by
Target Fund to its shareholders in liquidation and termination of Target Fund.
This opinion as to certain federal income tax consequences of the Transaction is
furnished to you pursuant to Sections 9(g) and 10(g) of the Agreement.
Capitalized terms not defined herein are defined in the Agreement.

         Target Fund is a series of the Target Trust which is registered under
the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
management investment company. Shares of Target Fund are redeemable at net asset
value at each shareholder's option. Target Fund has elected to be a regulated
investment company for federal income tax purposes under Section 851 of the
Internal Revenue Code of 1986, as amended (the "Code").

         Acquiring Fund is a series of the Acquiring Trust which is registered

         Based on the foregoing representations and our review of the documents

purposes:

         (i)      The Transaction will constitute a reorganization within the
                  meaning of Section 368(a) of the Code. Acquiring Fund and
                  Target Fund will each be a "party to a reorganization"
                  within the meaning of Section 368(b) of the Code;

         (ii)     No gain or loss will be recognized by Target Fund upon the
                  transfer of Target Fund's assets to Acquiring Fund in exchange
                  for Acquiring Fund Shares and the assumption by Acquiring Fund
                  of the liabilities of Target Fund, or upon the distribution of
                  Acquiring Fund Shares by Target Fund to its shareholders in
                  liquidation;

         (iii)    No gain or loss will be recognized by the Target Fund
                  shareholders upon the exchange of their Target Fund Shares for
                  Acquiring Fund Shares;

         (iv)     The basis of Acquiring Fund Shares a Target Fund shareholder
                  receives in connection with the Transaction will be the same
                  as the basis of his or her Target Fund Shares exchanged
                  therefor;

         (v)      A Target Fund shareholder's holding period for his or her
                  Acquiring Fund Shares will be determined by including the
                  period for which he or she held the Target Fund Shares
                  exchanged therefor, provided that he or she held such Target
                  Fund Shares as capital assets;

         (vi)     No gain or loss will be recognized by Acquiring Fund upon the
                  receipt of the assets of Target Fund in exchange for Acquiring

termination of Target Fund. This opinion as to certain federal income tax
consequences of the Transaction is furnished to you pursuant to Sections 9(g)

                  of the liabilities of Target Fund, or upon the distribution of

                  therefor;

         (v)      A Target Fund shareholder's holding period for his or her

         (ii)     No gain or loss will be recognized by Target Fund upon the

                  for Acquiring Fund Shares and the assumption by Acquiring Fund
                  of the liabilities of Target Fund, or upon the distribution of
                  Acquiring Fund Shares by Target Fund to its shareholders in
                  liquidation;

                  shareholders upon the exchange of their Target Fund Shares for

         (iv)     The basis of Acquiring Fund Shares a Target Fund shareholder
                  receives in connection with the Transaction will be the same
                  as the basis of his or her Target Fund Shares exchanged
                  therefor;

         (v)      A Target Fund shareholder's holding period for his or her
                  Acquiring Fund Shares will be determined by including the
                  period for which he or she held the Target Fund Shares
                  exchanged therefor, provided that he or she held such Target

Ladies and Gentlemen:

         We have acted as counsel in connection with the Agreement and Plan of
Reorganization dated as of November __, 1998 (the "Agreement"), between The One
Group (the "Acquiring Trust"), a Massachusetts business trust, on behalf of one
of its series, The One Group Mid- Cap Opportunity Fund ("Acquiring Fund") and
Pegasus Fund (the "Target Trust"), a Massachusetts business trust, on behalf of
one of its series, Pegasus Mid-Cap Opportunity Fund ("Target Fund"). The
Agreement describes a proposed transaction (the "Transaction") to occur on March
22, 1999, or such other date as may be decided by the parties (the "Exchange
Date"), pursuant to which Acquiring Fund will acquire substantially all of the
assets of Target Fund in exchange for shares of beneficial interest in Acquiring
Fund (the "Acquiring Fund Shares") and the assumption by Acquiring Fund of all
of the liabilities of Target Fund following which the Acquiring Fund Shares
received by Target Fund will be distributed by Target Fund to its shareholders
in liquidation and termination of Target Fund. This opinion as to certain
federal income tax consequences of the Transaction is furnished to you pursuant
to Sections 9(g) and 10(g) of the Agreement. Capitalized terms not defined
herein are defined in the Agreement.

         Target Fund is a series of the Target Trust which is registered under
the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
management investment company. Shares of Target Fund are redeemable at net asset
value at each shareholder's option. Target Fund has elected to be a regulated
investment company for federal income tax purposes under Section 851 of the
Internal Revenue Code of 1986, as amended (the "Code").

         For purposes of this opinion, we have considered the Agreement, the
Proxy Statement, the Registration Statement (including the items incorporated by
reference therein), and such other items as we have deemed necessary to render
this opinion. In addition, you provided us with a letter dated as of the date
hereof, representing as to certain facts, occurrences and information upon which
you have indicated that we may rely in rendering this opinion (whether or not
contained or reflected in the documents and items referred to above).

         Based on the foregoing representations and our review of the documents
and items referred to above, we are of the opinion that for federal income tax
purposes:

     (i)          The Transaction will constitute a reorganization within the
                  meaning of Section 368(a) of the Code. Acquiring Fund and
                  Target Fund will each be a "party to a reorganization" within
                  the meaning of Section 368(b) of the Code;

     (ii)         No gain or loss will be recognized by Target Fund upon the
                  transfer of Target Fund's assets to Acquiring Fund in exchange
                  for Acquiring Fund Shares and the assumption by Acquiring Fund
                  of the liabilities of Target Fund, or upon the distribution of
                  Acquiring Fund Shares by Target Fund to its shareholders in
                  liquidation;

     (iii)        No gain or loss will be recognized by the Target Fund
                  shareholders upon the exchange of their Target Fund Shares for
                  Acquiring Fund Shares;

     (iv)         The basis of Acquiring Fund Shares a Target Fund shareholder
                  receives in connection with the Transaction will be the same
                  as the basis of his or her Target Fund Shares exchanged
                  therefor;

     (v)          A Target Fund shareholder's holding period for his or her
                  Acquiring Fund Shares will be determined by including the
                  period for which he or she held the Target Fund Shares
                  exchanged therefor, provided that he or she held such Target
                  Fund Shares as capital assets;

     (vi)         No gain or loss will be recognized by Acquiring Fund upon the
                  receipt of the assets of Target Fund in exchange for Acquiring
                  Fund Shares and the assumption by Acquiring Fund of the
                  liabilities of Target Fund;

                  Target Fund transferred to Acquiring Fund in the Transaction
                  will be the same as the basis of such assets in the hands of

Ladies and Gentlemen:

         We have acted as counsel in connection with the Agreement and Plan of
Reorganization dated as of November __, 1998 (the "Agreement"), between The One
Group (the "Acquiring Trust"), a Massachusetts business trust, on behalf of one
of its series, The One Group Investor Growth Fund ("Acquiring Fund") and Pegasus
Fund (the "Target Trust"), a Massachusetts business trust, on behalf of one of
its series, Pegasus Managed Assets Growth Fund ("Target Fund"). The Agreement
describes a proposed transaction (the "Transaction") to occur on March 22, 1999,
or such other date as may be decided by the parties (the "Exchange Date"),
pursuant to which Acquiring Fund will acquire substantially all of the assets of
Target Fund in exchange for shares of beneficial interest in Acquiring Fund (the
"Acquiring Fund Shares") and the assumption by Acquiring Fund of all of the
liabilities of Target Fund following which the Acquiring Fund Shares received by
Target Fund will be distributed by Target Fund to its shareholders in
liquidation and termination of Target Fund. This opinion as to certain federal
income tax consequences of the Transaction is furnished to you pursuant to
Sections 9(g) and 10(g) of the Agreement. Capitalized terms not defined herein
are defined in the Agreement.

         Target Fund is a series of the Target Trust which is registered under
the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
management investment company. Shares of Target Fund are redeemable at net asset
value at each shareholder's option. Target Fund has elected to be a regulated
investment company for federal income tax purposes under Section 851 of the
Internal Revenue Code of 1986, as amended (the "Code").

         Acquiring Fund is a series of the Acquiring Trust which is registered
under the 1940 Act as an open-end management investment company. Shares of
Acquiring Fund are redeemable at net asset value at each shareholder's option.

         For purposes of this opinion, we have considered the Agreement, the
Proxy Statement, the Registration Statement (including the items incorporated by
reference therein), and such other items as we have deemed necessary to render
this opinion. In addition, you provided us with a letter dated as of the date
hereof, representing as to certain facts, occurrences and information upon which
you have indicated that we may rely in rendering this opinion (whether or not
contained or reflected in the documents and items referred to above).

         Based on the foregoing representations and our review of the documents
and items referred to above, we are of the opinion that for federal income tax
purposes:

     (i)          The Transaction will constitute a reorganization within the
                  meaning of Section 368(a) of the Code. Acquiring Fund and
                  Target Fund will each be a "party to a reorganization" within
                  the meaning of Section 368(b) of the Code;

     (ii)         No gain or loss will be recognized by Target Fund upon the
                  transfer of Target Fund's assets to Acquiring Fund in exchange
                  for Acquiring Fund Shares and the assumption by Acquiring Fund
                  of the liabilities of Target Fund, or upon the distribution of
                  Acquiring Fund Shares by Target Fund to its shareholders in
                  liquidation;

     (iii)        No gain or loss will be recognized by the Target Fund
                  shareholders upon the exchange of their Target Fund Shares for
                  Acquiring Fund Shares;

     (iv)         The basis of Acquiring Fund Shares a Target Fund shareholder
                  receives in connection with the Transaction will be the same
                  as the basis of his or her Target Fund Shares exchanged
                  therefor;

     (v)          A Target Fund shareholder's holding period for his or her
                  Acquiring Fund Shares will be determined by including the
                  period for which he or she held the Target Fund Shares
                  exchanged therefor, provided that he or she held such Target
                  Fund Shares as capital assets;

     (vi)         No gain or loss will be recognized by Acquiring Fund upon the
                  receipt of the assets of Target Fund in exchange for Acquiring
                  Fund Shares and the assumption by Acquiring Fund of the
                  liabilities of Target Fund;

     (vii)        The basis in the hands of Acquiring Fund of the assets of
                  Target Fund transferred to Acquiring Fund in the Transaction
                  will be the same as the basis of such assets in the hands of
