                            PURSUANT TO RULE 18f-3
                                    under the
                         INVESTMENT COMPANY ACT OF 1940

                                    The Plan

I.       Introduction

         As required by Rule 18f-3 under the Investment  Company Act of 1940, as
amended ("1940 Act"),  this Plan describes the  multi-class  system for the Fund
that will apply to shares of beneficial interest, $0.01 par value per share (the
"shares"), of Scudder S&P 500 Index Fund (the "Series"),  including the separate
class  arrangements  for  shareholder  and   administrative   services  and  the
distribution of shares,  the method for allocating  expenses,  income,  gain and
loss  of the  Fund  among  classes  and  any  related  exchange  privileges  and
conversion features applicable to the classes.

         Upon the effective date of this Plan, the Fund elects to offer multiple
classes of shares of the Series, as described herein, pursuant to Rule 18f-3 and
this Plan.

II.      The Multi-Class System

         The  Series may offer two  classes  of shares,  Class S shares and AARP
shares.  Shares of each class of each Series  shall  represent an equal pro rata
interest in the Series and,  generally,  shall have identical voting,  dividend,
liquidation, and other rights, preferences,  powers, restrictions,  limitations,
qualifications and terms and conditions,  except that: (a) each class shall have
a different designation; (b) each class of shares shall bear any Class Expenses,
as defined by Section A.2,  below;  (c) each class shall have  exclusive  voting
rights on any  matter  submitted  to  shareholders  that  relates  solely to its
shareholder services,  administrative services or distribution arrangements; (d)
each  class  shall  have  separate  voting  rights on any  matter  submitted  to
shareholders  in which the  interests of one class differ from the  interests of
any other class; (e) each class may have separate exchange privileges;  (f) each
class of shares may have separate account size requirements;  and (g) each class
may have different  conversion features.  In addition,  the following provisions
shall apply to the classes authorized hereby.

         A.       Allocation of Income and Expenses

                  1.       General.

                  The gross income,  realized and  unrealized  capital gains and
losses and expenses (other than Class Expenses,  as defined below) of the Series
shall be  allocated  to each share of the Series,  on the basis of its net asset
value relative to the net asset value of the Series. Expenses to be so allocated
include a portion of the expenses of the Fund that are not  attributable  to the
Series,  any  class  of the  Series  or any  other  series  of the  Fund  ("Fund
Expenses"), and expenses of the Series not attributable to a particular class of
the Series ("Series  Expenses").  Fund Expenses include, but are not limited to,
Trustees' fees,  certain insurance costs and certain legal fees. Series Expenses
include,  but are not limited to,  certain  filing fees (i.e.  state filing fees
imposed on a Fund-wide basis and Securities and Exchange Commission registration
fees),  custodial  fees,  advisory  fees  and  other  expenses  relating  to the
management of the Series' assets.

                  2.       Class Expenses.

                  Expenses attributable to one or more particular classes, which
are  allocated  on the basis of the  amount  incurred  on  behalf of each  class
("Class  Expenses")  may include:  (a)  transfer  agent fees  attributable  to a
specific  class,  (b) printing  and postage  expenses  related to preparing  and
distributing  material  such as  shareholder  reports,  prospectuses  and  proxy
materials to current Fund shareholders;  (c) registration fees (other than those
set forth in subsection A.l above); (d) the expense of administrative  personnel
and services as required to support the  shareholders of a specific  class;  (e)
litigation  or other  legal  expenses  and  audit or other  accounting  expenses
relating to a specific class;  (f) Trustees' fees incurred as a result of issues
relating to a specific  class;  and (g)  shareholder or Trustees'  meeting costs
that relate to a specific class. All expenses described in this paragraph may be
allocated as Class Expenses, but only if the Fund's President and Treasurer have
determined, subject to the Board of Trustees' approval or ratification, which of
such categories of expenses will be treated as Class  Expenses,  consistent with
applicable  legal principles under the 1940 Act and the Internal Revenue Code of
1986, as amended ("Code").

                  In the event that a particular expense is no longer reasonably
allocable  by class or to a  particular  class,  it shall be  treated  as a Fund
Expense or Series  Expense,  and in the event a Fund  Expense or Series  Expense
becomes allocable at a different level,  including as a Class Expense,  it shall
be so  allocated,  subject  to  compliance  with Rule 18f-3 and to  approval  or
ratification by the Board of Trustees.

                  The initial  determination  of expenses that will be allocated
as Class  Expenses and any subsequent  changes  thereto shall be reviewed by the
Board of Trustees  and  approved by such Board and by a majority of the Trustees
who are not "interested  persons" of the Fund or Series,  as defined in the 1940
Act (the "Independent Trustees").  Such expense allocation shall be set forth in
a schedule, as amended from time to time, by the Board of Trustees,  including a
majority of the Independent Trustees, and shall form a part of this plan.

                  3.       Waivers or Reimbursements of Expenses

                  Expenses may be waived or reimbursed by the Fund's  investment
adviser,  its principal  underwriter,  or any other  provider of services to the
Series or the Fund  without  the prior  approval of the Board of Trustees to the
extent such waiver or  reimbursement  does not jeopardize the Fund's status as a
"regulated investment company" under the Code.

         B.       Exchange Privileges

         Shareholders  of the  Series  may  exchange  shares of their  class for
shares of a similar class of another fund in the Scudder family, at the relative
net asset  values of the  respective  shares to be  exchanged  and with no sales
charge, subject to applicable law, and to the applicable  requirements,  if any,
as to minimum amount.

         C.       Conversion Privilege

         Upon the  direction  of a holder of Class S shares or Class AARP shares
of the Series, such shares will be converted to AARP shares or Class S shares of
the Series,  respectively,  at the relative net asset values of the two classes.
Any  conversion  of shares of one Class to shares of another Class is subject to
the continuing  availability  of a ruling of the Internal  Revenue Service or an
opinion of counsel to the effect that the conversion of shares should constitute
a taxable  event  under  federal  income  tax law.  Any such  conversion  may be
suspended if such a ruling or opinion is no longer available.

         D.       Board Review

                  1.       Initial Approval

                  The Board of Trustees, including a majority of the Independent
Trustees,  at a  meeting  held  March 14,  2000,  approved  the Plan  based on a
determination that the Plan,  including the expense  allocation,  is in the best
interests  of each class  individually  and of the  Series  and the Fund.  Their
determination  was based on their review of information  furnished to them which
they deemed reasonably necessary and sufficient to evaluate the Plan.

                  2.       Approval of Amendments

                  The Plan may not be  amended  materially  unless  the Board of
Trustees,  including a majority of THE INDEPENDENT TRUSTEES,  has found that the
proposed amendment, including any proposed related expense allocation, is in the
best interests of each class  individually  and of the Series and the Fund. Such
finding shall be based on information  requested by, and furnished to, the Board
that the Board deems reasonably necessary to evaluate the proposed amendment.

                  3.       Periodic Review

                  The Board shall review reports of expense allocations and such
other  information as they request at such times,  or pursuant to such schedule,
as they may determine is consistent with applicable legal requirements.

         E.       Contracts

         Any  Agreement  related to the  multi-class  system  shall  require the
parties  thereto to furnish to the Board of Trustees,  upon their request,  such
information  as is  reasonably  necessary to permit the Trustees to evaluate the
plan or any proposed amendment.

         F.       Effective Date

         The Plan,  having been  reviewed  and approved by the Board of Trustees
and by a majority of the Independent  Trustees as indicated in subsection C.l of
Section  II of the  Plan,  shall  take  effect as of the  implementation  of the
multi-class  system,  except that  allocation of Class  Expenses shall not occur
until  the  effective  date  of  the  Fund's  post-effective  amendment  to  its
registration statement containing disclosure concerning the multi-class system.



         G.       Amendments

         The Plan may not be amended to modify  materially its terms unless such
amendment has been approved in the manner specified in subsection C.2 of Section
II of the Plan.
