RE:      AGREEMENT AND PLAN OF REORGANIZATION,  DATED MAY __, 2009 (THE "PLAN"),
         ADOPTED  BY THE  BOARD OF  TRUSTEES  OF THE  RYDEX  SERIES  FUNDS  (THE
         "TRUST") FOR THE  REORGANIZATION OF THE TRUST'S HEDGED EQUITY FUND (THE
         "ACQUIRED FUND") INTO THE TRUST'S MULTI-HEDGE STRATEGIES FUND, FORMERLY
         THE ABSOLUTE RETURN STRATEGIES FUND (THE "SURVIVING FUND")

Ladies and Gentlemen:

                  You have  requested  our opinions as to certain  U.S.  federal
income tax  consequences  of the  reorganization  of the  Acquired  Fund and the
Surviving  Fund that will  consist of: (i) the  transfer of all of the assets of
the Acquired Fund to the Surviving Fund in exchange solely for H-Class,  A-Class
and C Class shares of the Surviving Fund  ("Surviving  Fund  Shares"),  (ii) the
assumption by the Surviving Fund of all of the liabilities of the Acquired Fund,
and (iii) the  distribution of the Surviving Fund Shares to the  shareholders of
the Acquired Fund(1) in complete  liquidation of the Acquired Fund, all upon the
terms and conditions set forth in the Plan (the "Reorganization").

                  In rendering  our  opinions,  we have reviewed and relied upon
(a) the Plan, (b) certain representations  concerning the Reorganization made to
us by the Trust,  on behalf of the funds,  in a letter dated _____ __, 2009 (the
"Representation  Letter"), (c) all other documents,  financial and other reports
and  corporate  minutes  that we deemed  relevant or  appropriate,  and (d) such
statutes, regulations,  rulings and decisions as we deemed material with respect
to this opinion.  All terms used herein,  unless otherwise defined,  are used as
defined in the Plan.

                  For  purposes  of our  opinions,  we  have  assumed  that  the
Acquired  Fund  and  the  Surviving  Fund,  as of  the  Effective  Time  of  the
Reorganization,  each satisfy and, following the  Reorganization,  the Surviving
Fund will continue to satisfy,  the requirements of subchapter M of the Internal
Revenue Code of 1986, as amended (the "Code"),  for qualification as a regulated
investment company ("RIC").

                  Based on the  foregoing,  and provided the  Reorganization  is
carried out in accordance  with the laws of the State of Delaware,  the Plan and
the Representation Letter, it is our opinion that:

                  1. The Reorganization will constitute a tax-free
         reorganization within the meaning of Section 368(a) of the Code, and
         the Acquired Fund and the Surviving Fund will each be a "party to the
         reorganization" within the meaning of Section 368(b) of the Code.

                  2. No gain or loss will be recognized by the Surviving Fund
         upon the receipt of the assets of the Acquired Fund solely in exchange
         for Surviving Fund Shares and the assumption by



--------------------------------------
(1)      In the distribution, Acquired Fund shareholders who hold Acquired Fund
         H-Class, A-Class and C-Class shares will receive Surviving Fund
         H-Class, A-Class and C-Class shares, respectively.

         the  Surviving  Fund of all of the  liabilities  of the Acquired  Fund,
         pursuant to Section 1032(a) of the Code.

                  3. No gain or loss will be  recognized  by the  Acquired  Fund
         upon the transfer of all of its assets to the Surviving  Fund solely in
         exchange for Surviving  Fund Shares and the assumption by the Surviving
         Fund  of all of the  liabilities  of the  Acquired  Fund  or  upon  the
         distribution  of Surviving Fund Shares to  shareholders of the Acquired
         Fund, pursuant to Sections 361(a) and (c) and 357(a) of the Code.

                  4. No gain or loss will be recognized by the  shareholders  of
         the  Acquired  Fund upon the  exchange of their  shares of the Acquired
         Fund for Surviving Fund Shares  (including  fractional  shares to which
         they may be entitled), pursuant to Section 354(a) of the Code.

                  5. The aggregate tax basis of Surviving  Fund Shares  received
         by each shareholder of the Acquired Fund (including  fractional  shares
         to which they may be entitled)  will be the same as the  aggregate  tax
         basis of the  Acquired  Fund  shares  exchanged  therefor,  pursuant to
         Section 358(a)(1) of the Code.

                  6. The holding period of the Surviving Fund Shares received by
         the shareholders of the Acquired Fund (including  fractional  shares to
         which they may be  entitled)  will  include the  holding  period of the
         Acquired Fund shares  surrendered in exchange  therefor,  provided that
         the  Acquired  Fund  shares  were  held as a  capital  asset  as of the
         Effective Time of the  Reorganization,  pursuant to Section  1223(1) of
         the Code.

                  7. The tax basis of the assets of the Acquired Fund received
         by the Surviving Fund will be the same as the tax basis of such assets
         to the Acquired Fund immediately prior to the exchange, pursuant to
         Section 362(b) of the Code.

                  8. The  holding  period  of the  assets of the  Acquired  Fund
         received by the  Surviving  Fund will  include the period  during which
         such assets were held by the Acquired Fund, pursuant to Section 1223(2)
         of the Code.

                  9. The  Surviving  Fund will succeed to and take into account,
         as of the date of the transfer (as defined in Section  1.381(b)-1(b) of
         the Treasury Regulations),  the items of the Acquired Fund described in
         Section 381(c) of the Code,  subject to the conditions and  limitations
         specified in Sections 381(b) and (c), 382, 383 and 384 of the Code.

                  Notwithstanding   the  foregoing   opinions,   no  opinion  is
         expressed  as to the effect of the  Reorganization  on (i) the Acquired
         Fund or the  Surviving  Fund with  respect to any asset as to which any
         unrealized  gain or loss is required to be recognized for U.S.  federal
         income tax purposes at the end of a taxable year (or on the termination
         or transfer  thereof) under a  mark-to-market  system of accounting and
         (ii) any shareholder of the Acquired Fund that is required to recognize
         unrealized  gains and losses for U.S. federal income tax purposes under
         a mark-to-market system of accounting.
