SECURITY TAX-EXEMPT FUND
MEMBER OF THE SECURITY BENEFIT GROUP OF COMPANIES
700 SW HARRISON STREET, TOPEKA, KANSAS 66636-0001

   
                 SPECIAL MEETING OF STOCKHOLDERS, APRIL 24, 1998
                                 PROXY STATEMENT
                     SOLICITATION AND REVOCATION OF PROXIES

   The enclosed proxy is solicited by and on behalf of the Board of Directors of
Security  Tax-Exempt Fund (the "Fund") and is revocable by timely  submission to
the  Secretary of the Fund of another proxy or of notice of revocation in proper
written form,  or by voting the shares in person at the Meeting.  A second proxy
form may be obtained from the Secretary of Security Tax-Exempt Fund. The cost of
soliciting  proxies will be borne by Security  Management  Company,  LLC, 700 SW
Harrison Street,  Topeka, Kansas 66636-0001 ("SMC" or the "Investment Manager"),
which  will  be  reimbursed  by the  Fund.  SMC is the  investment  adviser  and
administrator  of the Fund. In addition to  solicitations  by mail,  some of the
Investment  Manager's officers and employees,  without extra  remuneration,  may
conduct additional solicitation by telephone, telegraph and personal interviews.
Proxies are expected to be mailed on or about March 10, 1998.
    

                                VOTING SECURITIES

   
   Only stockholders of record at the close of business on February 25, 1998 are
entitled to vote at the special Meeting. On that date, the outstanding number of
voting securities of the Fund was as follows:  2,099,996.525  Class A shares and
175,858.125 Class B shares, all of which are common stock of the Fund of the par
value of $0.10 per share. Each share is entitled to one vote.

   Approval of the Sub-Advisory  Contract,  Proposal No. 1, approval of the name
change,  Proposal  No. 2a,  approval  of the amended  fundamental  policy no. 1,
Proposal No. 2b and approval of the amended  fundamental  policy no. 8, Proposal
No. 3, requires the affirmative  majority vote of the outstanding  shares of the
common  stock of the  Fund.  The  Class A and Class B shares of the Fund will be
voted  together on Proposal Nos. 1, 2a, 2b and 3 due to the  commonality  of the
interest of the two classes of shares with respect to those proposals.

   With respect to approval of the Class A  Distribution  Plan,  Proposal No. 4,
and approval of the amendment of the Investment Advisory Contract,  Proposal No.
5, the Class A and Class B shares of the Fund will vote  separately  because  of
the  differing  interests  in  those  proposals  of  the  Class  A and  Class  B
shareholders.  Class  A  shareholders  would  be  affected  immediately  by  the
proposals, if approved, whereas Class B shareholders would not be affected until
their  Class B shares  convert  to Class A shares  automatically  on the  eighth
anniversary  of their  purchase.  Approval of Proposal Nos. 4 and 5 requires the
affirmative  majority vote of the shares of each class for approval with respect
to that class.
    
- --------------------------------------------------------------------------------
THE FUND WILL FURNISH,  WITHOUT CHARGE,  A COPY OF THE ANNUAL REPORT  CONTAINING
AUDITED  FINANCIAL  STATEMENTS  FOR THE FISCAL YEAR ENDED DECEMBER 31, 1997 TO A
SHAREHOLDER UPON REQUEST. SUCH REQUESTS SHOULD BE DIRECTED TO AMY LEE, SECRETARY
OF THE  FUND,  BY  WRITING  THE  FUND AT 700 SW  HARRISON  ST.,  TOPEKA,  KANSAS
66636-0001,  OR BY CALLING THE FUND'S TOLL-FREE TELEPHONE NUMBER 1-800-888-2461,
EXTENSION 3127.



   
   A  "majority  vote" is  defined  as the vote of either 67  percent or more of
voting  securities  of the Fund (or, if  applicable,  the class)  present at the
meeting  in person or by proxy,  or more  than 50  percent  of such  outstanding
voting  securities,  whichever  is less.  With  respect  to  Proposal  No. 2a, a
majority  vote is defined as the  affirmative  vote of a majority  of the Fund's
outstanding voting securities.

- --------------------------------------------------------------------------------------------------------------
                                                              
1.  Approval of Sub-Advisory Contract                            Class A and Class B shareholders

5.  Approval of Amendment of the Investment Advisory Contract    Class A and Class B shareholders - separately
- --------------------------------------------------------------------------------------------------------------


   The  presence,  in  person  or by  proxy,  of  more  than 50  percent  of the
outstanding  shares of the Fund or, with  respect to Proposal  Nos. 4 and 5, the
Class A and Class B shares,  respectively,  will be  sufficient  to  establish a
quorum for the conduct of business at the Meeting.  Shares held by  stockholders
present in person or  represented  by proxy at the Meeting  will be counted both
for the purpose of determining  the presence of a quorum and for calculating the
votes cast on the proposals before the Meeting. Shares represented by timely and
properly executed proxies will be voted as specified.  Executed proxies that are
unmarked  will be voted in favor of the proposals  presented at the Meeting.  An
abstention on any proposal, either by proxy or by vote in person at the Meeting,
will be counted for purposes of  establishing a quorum,  but has the same effect
as a negative vote.

   In the event that a  sufficient  number of votes to approve a proposal is not
received,  the persons named as proxies may propose one or more  adjournments of
the Meeting to permit further  solicitation of voting  instructions,  or for any
other  purpose.  A vote may be taken on any proposal  prior to an adjournment if
sufficient  votes have been received for approval.  Any adjournment will require
the affirmative vote of a majority of those shares represented at the Meeting in
person or by proxy. Unless otherwise instructed,  proxies will be voted in favor
of any  adjournment.  At any  subsequent  reconvening  of the  Meeting,  proxies
(unless previously  revoked) will be voted in the same manner as they would have
been voted at the Meeting.
    

                                 PROPOSAL NO. 1
                 APPROVAL OF A SUB-ADVISORY CONTRACT BETWEEN SMC
                   AND SALOMON BROTHERS ASSET MANAGEMENT INC.

   The Fund's stockholders are asked to approve a sub-advisory agreement between
SMC and Salomon Brothers Asset Management Inc. ("Salomon" or the "Sub-Adviser").
If this  Proposal  No. 1 is approved by the  stockholders,  Salomon will provide
sub-advisory  services to the Fund pursuant to a sub-advisory  contract  between
SMC and Salomon (the  "Sub-Advisory  Contract").  The Fund's Board of Directors,
including a majority of the disinterested  Directors,  approved the Sub-Advisory
Contract at a meeting held on February 6, 1998.

                                        2


   THE BOARD OF  DIRECTORS  RECOMMENDS  THAT THE  FUND'S  STOCKHOLDERS  VOTE FOR
APPROVAL OF THE SUB-ADVISORY CONTRACT.

                      EXISTING INVESTMENT ADVISORY CONTRACT

   The Investment Manager has served as investment adviser of the Fund since its
inception in accordance with the terms of an Investment  Advisory Contract dated
October 7, 1983, as amended (the "Advisory Contract"). The Advisory Contract was
approved  initially by shareholders on April 24, 1984 and has not been submitted
to  shareholders  for  approval  since that date.  The  contract  was renewed by
directors of the Fund  (including a majority of directors who are not parties to
the contract or interested  persons of any such party) on February 6, 1998.  The
Advisory  Contract will  continue in effect until May 1, 1999,  and from year to
year thereafter providing such continuance is specifically  approved by the vote
of a majority of the Board of  Directors  of the Fund  (including  a majority of
such directors who are not parties to the contract or interested  persons of any
such party) cast in person at a meeting  specifically  called for voting on such
renewal.

   
   Under the Advisory  Contract,  the Investment Manager furnishes the Fund with
investment  research and advice and an investment  program,  including decisions
regarding  which  securities  to purchase and sell and what portion of assets to
hold uninvested.  In addition,  the Investment Manager arranges for the purchase
and sale of securities and other  investments  held by the Fund and provides for
the compilation and maintenance of records relating to its duties as required by
the rules and regulations of the Securities and Exchange  Commission ("SEC"). No
brokerage commissions were paid by the Fund to an affiliated broker for the year
ended December 31, 1997.

   For its services,  the Investment  Manager receives from the Fund a fee equal
to 0.50  percent  of the  average  net  assets of the Fund,  computed  daily and
payable monthly.  The Investment Manager received from the Fund advisory fees of
$115,812 during the year ended December 31, 1997.

   The Advisory  Contract  provides that the aggregate  annual expenses of every
character,  exclusive of brokerage commissions,  interest, taxes,  extraordinary
expenses (such as litigation) and distribution  fees paid under the Fund's Class
B Distribution  Plan, but inclusive of the  Investment  Manager's  compensation,
shall not exceed an amount equal to one percent of the Fund's  average daily net
assets. The Investment Manager agrees to contribute such funds to the Fund or to
waive such portion of its  compensation as may be necessary to insure that total
annual expenses will not exceed this amount. (It is proposed that this provision
of the Advisory Contract be amended. See "Proposal No. 5," page 13.)
    

   The Advisory  Contract  may be  terminated  without  penalty at any time upon
sixty days' notice by the Board of Directors of the Fund, by vote of the holders
of a  majority  of the  outstanding  voting  securities  of the Fund,  or by the
Investment Manager. The Contract is terminated automatically in the event of its
assignment (as such term is defined in the Investment Company Act of 1940).

   The Investment Manager also serves as the Fund's  administrative and transfer
agent. For those services, the Investment Manager received from the Fund $20,846
and $15,105, respectively, during the year ended December 31, 1997.

                         PROPOSED SUB-ADVISORY CONTRACT

   On behalf of the Fund,  SMC  proposes to enter into a  sub-advisory  contract
("Sub-Advisory  Contract")  with Salomon,  a form of which is attached hereto as
Exhibit "A". The  Sub-Advisory  Contract was proposed by SMC and was unanimously
approved by the Board of  Directors  of the

                                       3


   
Fund  (including  a  majority  of such  directors  who are not  parties  to such
contract or  interested  persons of any such  party) on  February  6, 1998.  SMC
proposed the Sub-Advisory  Contract because it believes that the Sub-Adviser has
expertise  with  respect  to  municipal  securities  that would be  valuable  in
managing the Fund's investments.

   Under the Sub-Advisory  Contract,  the Sub-Adviser will furnish the Fund with
investment  research  and advice in  connection  with the Fund's  investment  in
securities and will effect purchases and sales of portfolio securities,  subject
to the  policies and control of the Board of Directors  and the  supervision  of
SMC. For its services, the Sub-Adviser will receive from SMC an annual fee equal
to 0.22  percent of the  average  daily  closing  value of the net assets of the
Fund,  computed  on a daily basis and  payable  monthly.  Under the terms of the
Sub-Advisory  Contract,  the  Sub-Adviser is not subject to any liability to the
Fund or the Investment  Manager  connected with any services  rendered under the
Sub-Advisory  Contract  except by reason of willful  misfeasance,  bad faith, or
gross  negligence in the  performance  of its duties or by reason of a breach of
its duties under the Sub-Advisory Contract.
    

   The  Sub-Adviser  has agreed to pay its expenses in connection with providing
the  sub-advisory  services,  including any expenses  associated  with preparing
reports for the Fund's Board of Directors and expenses of travel by employees of
the  Sub-Adviser in connection with such reports as well as any expenses that it
may incur in communicating with SMC.

   Approval of the  Sub-Advisory  Contract will not increase or decrease any fee
or  expense  paid by the Fund or its  stockholders  because  all fees  under the
Sub-Advisory  Contract  are paid by SMC.  The fees  earned by SMC for  providing
advisory  services to the Fund will be reduced,  however,  by the amount paid to
the Sub-Adviser pursuant to the Sub-Advisory Contract.

   During the fiscal year ended  December 31, 1997, the Fund paid SMC a total of
$115,812 for services provided under the Advisory Contract.  If the Sub-Advisory
Contract had been in effect during the 1997 fiscal year, SMC would have paid the
Sub-Adviser $50,957 for services provided under that contract.

   
   It is expected that the Sub-Advisory Contract will become effective on May 1,
1998, provided that on the Meeting date it is approved by a majority vote of the
holders of the  outstanding  voting  securities  of the Fund.  The contract will
continue in force until May 1, 1999, and from year to year thereafter,  provided
such  continuance  is  specifically  approved  by a  majority  of the  Board  of
Directors  of the Fund  (including  a  majority  of such  directors  who are not
parties to the Sub-Advisory  Contract or interested  persons of any such party).
The  Sub-Advisory  Contract may be terminated  without  penalty upon sixty days'
written  notice by either  party or by vote of the Board of Directors or by vote
of a majority of the holders of the outstanding  voting  securities of the Fund.
The  Sub-Advisory  Contract  will  automatically  terminate  in the event of the
termination of the Advisory Contract between SMC and the Fund or in the event of
its assignment.
    

   In recommending the approval of the Sub-Advisory Contract to the stockholders
of the  Fund,  the  Board of  Directors  considered  such  factors  as it deemed
reasonably  necessary and  appropriate,  including (1) the nature and quality of
the services to be provided to the Fund; (2) the fairness of the compensation of
the  Sub-Adviser;  (3) the financial  soundness of the Sub-Adviser to render all
necessary services to the Fund; (4) comparative industry advisory fee structures
and expense ratios for the Fund including, specifically, the relationship of the
proposed advisory fee rates to those typically charged similar mutual funds; (5)
the performance of a similar portfolio  managed by the Sub-Adviser;  and (6) the
total fees paid by the Fund,  including  12b-1  plan fees.  The Board gave equal
weight to each of the above factors when  considering  approval of the contract.
Based on the

                                       4


considerations  above,  the Board believes that (a) Salomon has the expertise to
provide  high-quality  services to the Fund;  (b) the advisory fee rates paid by
the Fund and paid by SMC under the  Sub-Advisory  Contract are fair, and similar
to those typically charged similar mutual funds; (c) the financial  soundness of
Salomon  is  sufficient  for  Salomon  to render all  necessary  services  to be
provided under the Sub-Advisory  Contract;  and (d) approval of the Sub-Advisory
Contract  will not change the total fees paid by the Fund  because  SMC pays all
fees under the Sub-Advisory Contract.

   The Board of Directors  of the Fund  unanimously  recommends  approval of the
Sub-Advisory  Contract by a vote in favor of  Proposal  No. 1. In the event that
the  proposed  contract is not  approved,  the Board of  Directors  will meet to
consider  whether to present  another  sub-advisory  contract for approval or to
have SMC continue to provide such advisory services.

                           THE PROSPECTIVE SUB-ADVISER

                             PROPOSAL NOS. 2A AND 2B
        APPROVAL OF AMENDMENT OF THE ARTICLES OF INCORPORATION TO CHANGE
          THE FUND'S NAME AND APPROVAL OF CHANGE IN FUNDAMENTAL POLICY

   The  Fund's  Board  of  Directors  approved  amendment  of  the  Articles  of
Incorporation  to change the Fund's name to  Security  Municipal  Bond Fund.  In
addition,  the  Fund's  Board  of  Directors  approved  a change  in the  Fund's
fundamental policies to allow investment of its assets in tax-exempt  securities
which may be subject to alternative  minimum tax. The Board approved the changes
at its meeting of February 6, 1998.

   The Fund's current fundamental investment policy no. 1 is as follows:

1.  Not to  invest  more  than 20% of its  assets  in  securities  which are not
    tax-exempt securities, except for temporary defensive purposes.

   As amended, the Fund's fundamental policy would read as follows:

1.  Not to invest  less than 80% of its  assets in  securities  which are exempt
    from  regular  federal  income tax but which may be  subject to  alternative
    minimum tax, except for temporary defensive purposes.

   The Board of Directors  determined that this change in the Fund's fundamental
investment policy, which would eliminate the requirement that the Fund invest 80
percent of its assets in  tax-
    

                                       6


exempt  securities that are also exempt from the alternative  minimum tax, could
be made only if it changed the Fund's name for the reasons discussed below.

   
   The staff of the SEC takes the  position  that if a fund's name  implies that
its  distributions  will be exempt  from  federal  income  tax, it should have a
fundamental  policy  requiring that during periods of normal market  conditions,
the fund will (1)  invest  its  assets  so that 80  percent  of  income  will be
tax-exempt,  or (2)  invest at least 80  percent  of its  assets  in  tax-exempt
securities.  The SEC staff considers that securities or income are  "tax-exempt"
only if they  are  also  exempt  from  alternative  minimum  tax.  The  Board of
Directors proposes to change the Fund name and amend its fundamental policies to
allow investment in tax-exempt securities that may be subject to the alternative
minimum tax.

   The Board of Directors  believes that  investment in private  activity bonds,
which are subject to the  alternative  minimum tax,  would be beneficial for the
Fund in light of the increased  yields that may be available  from  investing in
such securities.  Private activity bonds may be issued by or on behalf of public
authorities to finance various privately operated facilities and are not payable
from the unrestricted revenues of the issuer. As a result, the credit quality of
private activity bonds is frequently  related directly to the credit standing of
private   corporations  or  other  entities.   The  Board  determined  that  the
flexibility  to invest  more than 20  percent  of the  Fund's  assets in private
activity bonds was in the best interests of the Fund and its  shareholders.  The
Board noted,  however, that the Fund would no longer be appropriate for, or at a
minimum  could be less  attractive  to,  its  shareholders  who are  subject  to
alternative  minimum tax.  Based on the foregoing  considerations,  the Board of
Directors  determined  that  changing  the name of the Fund and its  fundamental
investment policies is in the best interests of the Fund and its shareholders.

   THE BOARD OF DIRECTORS  RECOMMENDS THAT STOCKHOLDERS VOTE FOR APPROVAL OF THE
CHANGE OF THE FUND'S NAME AND THE CHANGE IN FUNDAMENTAL POLICY.
    

                                 PROPOSAL NO. 3
                    APPROVAL OF CHANGE IN FUNDAMENTAL POLICY

   The Board of Directors  proposes to amend the Fund's  fundamental  investment
policies to increase  the  percentage  of the Fund's  total  assets which may be
invested in any one issuer. The proposed amendment would permit the Fund greater
flexibility to invest in securities  considered by the Investment Manager or, if
Proposal No. 1 is approved,  the Sub-Adviser,  to present attractive  investment
opportunities. Under the amended policy, the fund would be limited, with respect
to 75 percent of its total  assets,  to  investing no more than 5 percent of its
total assets in the securities of any one issuer.  However,  no such  limitation
would apply with respect to the remaining 25 percent of the Fund's assets.

   
   The Fund's current fundamental investment policy no. 8 is as follows:
    

8.  Not to invest more than 5% of its total assets in the  securities of any one
    issuer,  except securities issued or guaranteed by the U.S. government,  its
    agencies or instrumentalities.

   As amended, the Fund's fundamental policy would read as follows:

8.  Not to purchase a security if, as a result, with respect to 75% of the value
    of its total assets,  more than 5% of the value of its total assets would be
    invested in the securities of any one issuer,  except  securities  issued or
    guaranteed by the U.S. government, its agencies or instrumentalities.

                                       7


   
   By allowing the Fund to invest a  significantly  larger portion of its assets
in the  securities  of a single  issuer,  this  proposed  change in  fundamental
policy,  while  consistent  with the Fund's  status  under  applicable  law as a
"diversified"  investment  company,  could  cause the Fund's net asset value per
share to be more  affected  by changes in the value of,  and  developments  with
respect to, the  securities of a single  issuer or a smaller  number of issuers.
The Board of Directors,  however,  believes  that the  advantages of this change
outweigh  the  risks.  The  Sub-Adviser   recommended  the  proposed  change  in
fundamental policy to provide more flexibility in managing the Fund's portfolio.
This  change  would allow the  Sub-Adviser  to invest more than 5 percent of the
Fund's  assets  (up to 25  percent)  in a  single  security.  As a  result,  the
Sub-Adviser  could  elect to  reduce  the  number  of  portfolio  securities  it
monitors,  or take a larger position in a security that the Sub-Adviser believes
is  attractive  with respect to yield and duration.  Such  positions may make it
easier to achieve the duration that the Sub-Adviser  believes is appropriate for
the Fund and also may allow the Sub-Adviser to anchor the  portfolio's  yield by
taking a larger position in a security with attractive  yield and call features.
The Board of Directors, after consideration of the increased potential risks and
potential  benefits  associated  with this change,  determined that the proposed
change in fundamental investment policy is in the best interests of the Fund and
its shareholders.
    

   THE BOARD OF DIRECTORS  RECOMMENDS THAT  SHAREHOLDERS  VOTE FOR THIS PROPOSAL
NO. 3.

                                 PROPOSAL NO. 4
                     APPROVAL OF A CLASS A DISTRIBUTION PLAN

   
   The holders of the Fund's shares are asked to approve a Class A  Distribution
Plan (the  "Plan") a form of which is attached  hereto as Exhibit "B". The Board
of  Directors  of the Fund,  including a majority of the  Directors  who are not
interested  persons  of the Fund and who have no  direct or  indirect  financial
interest in the operation of the Plan or any related agreement (the "Independent
Directors"), approved the Plan at a meeting held on February 6, 1998.

   THE BOARD OF  DIRECTORS  RECOMMENDS  THAT THE  FUND'S  STOCKHOLDERS  VOTE FOR
APPROVAL OF THE CLASS A DISTRIBUTION PLAN.

   As  discussed  under  "Voting  Securities"  above,  the  Class A and  Class B
stockholders  have differing  interests in this Proposal and,  accordingly,  the
Class A and Class B stockholders  will vote  separately with respect to approval
of the Plan.  If this  Proposal  No. 4 is  approved  by a  majority  vote of the
stockholders of each class, the Plan will be implemented  effective May 1, 1998.
If the Plan is approved  by a majority  vote of the holders of Class A shares of
the Fund but is not so  approved  by  holders  of Class B  shares,  the Board of
Directors will consider its options with respect to the Plan,  including whether
to implement the Plan. If the Board determines to implement the Plan without the
approval  of a majority  vote of the Class B shares,  the Fund will create a new
class of  shares  for Class B  shareholders  upon  conversion.  The new class of
shares would mirror Class A shares prior to implementation of the Plan.

   The Plan provides that the Fund will pay the Fund's principal underwriter and
distributor, Security Distributors, Inc. (the "Distributor"), a distribution fee
charged against the assets of the Fund's Class A shares. The distribution fee is
an amount  equal to 0.25  percent on an annual  basis of the  average  daily net
assets of the Fund's Class A shares,  calculated daily and payable monthly.  The
distribution  fee is to finance  activities  which  are,  or may be deemed to be
primarily  intended to result in the sale of Fund  shares.  The  Distributor  is
reimbursed under the Plan for  distribution-related  expenses actually incurred.
The Distributor  currently uses its own funds to engage in such activities,
    

                                       8


and the  distribution  fees  would  supplement  these  expenditures  and in some
instances may replace such  expenditures.  The distribution  fees may be used to
pay for the following distribution-related activities: (1) preparation, printing
and  distribution  of the Prospectus and Statement of Additional  Information in
connection with the offering of shares to the public; (2) printing of additional
copies  of  reports  and  other  shareholder   communications  for  use  by  the
Distributor as sales literature;  (3) preparation,  printing and distribution of
any other sales  literature  used in connection with the offering of Fund shares
to the public;  (4)  expenses  incurred in  advertising,  promoting  and selling
shares of the Fund to the public;  (5) service  fees to  securities  dealers for
answering  shareholder  inquiries,  recordkeeping and similar services;  and (6)
expenses  incurred  in  promoting  shares  of the  Fund to  securities  dealers,
including the costs of  preparation of materials for  presentations  to dealers,
travel expenses, costs of entertainment and other similar expenses.

   The Plan  requires  the  Distributor  to  provide  for review by the Board of
Directors  quarterly  reports of how  distribution  fees were  spent  during the
preceding quarter.  The Plan provides that the Distributor must submit for Board
approval each year a budget outlining proposed  distribution-related  activities
to be financed under the Plan during the upcoming fiscal year.

   
   The Plan states that it may not be amended to increase materially the amounts
to be paid by the Fund  thereunder  without a majority  vote of the  outstanding
voting  securities  of each class of shares for  approval  with  respect to that
class,  and all material  amendments are required to be approved by the Board of
Directors of the Fund,  including a majority of Independent  Directors,  cast in
person at a meeting  called for that purpose.  The Plan may be terminated at any
time by vote of a majority of Independent Directors or by a majority vote of the
outstanding Class A voting securities.  In the event the Plan is terminated,  it
provides  that  distribution  fees  paid to the  Distributor  up to the  date of
termination  would be retained by the Distributor,  and any expenses incurred by
the Distributor in excess of those fees would be the sole  responsibility of the
Distributor.
    

   While the Plan is in effect,  the  selection and  nomination  of  Independent
Directors  of the Fund must be committed to the  discretion  of the  Independent
Directors.

   
   The Board of Directors  recommends  approval of the Class A Distribution Plan
primarily  based upon the  Directors'  belief that the Plan is necessary for the
Fund  to be  competitive  and  to  attract  and  retain  assets.  The  Directors
anticipate that distribution fees would be used primarily to pay service fees to
broker/dealers to obtain certain administrative  services for the Fund's Class A
stockholders.  Those administrative  services may include processing new account
applications  and serving as the primary  source of  information to customers in
answering  questions  concerning the Fund and their  transactions with the Fund.
Payment of service fees has become common in the mutual fund  industry,  and the
Board  believes that because the Fund does not have a  Distribution  Plan,  many
securities  dealers assume that such service fees are not available with respect
to the Fund and that dealers will not be paid for providing  ongoing services to
Fund shareholders. As a result, many such dealers may elect to make available to
their customers mutual funds that have distribution plans in place,  rather than
the Fund. It is important to note that although many dealers assume that service
fees are not available,  the Investment  Manager currently pays a service fee to
securities  dealers  generally  equal to 0.25 percent of the aggregate net asset
value of the dealer's Class A accounts  opened after July 31, 1990. As a result,
if the Plan is  adopted,  the  expense of service  fees  currently  borne by the
Investment Manager will be paid by the Distributor from the Fund's  distribution
fees.

   The Directors also considered whether the Investment Manager would be willing
to pay service fees to securities dealers in the future.  They noted that if the
proposed Sub-Advisory Contract were adopted, the Investment Manager's expense of
managing the Fund would  increase by  approximately
    

                                       9


   
the amount of sub-advisory fees paid to Salomon, although the Investment Manager
also will realize a decrease in certain  expenses  associated  with managing the
Fund. As a result,  the Directors  concluded that the Investment  Manager may by
less willing to pay service fees in the future.

   In addition to the  considerations  discussed above, the Board considered the
benefits  of  having  available  distribution  fees for  additional  promotional
activities.  The Fund's assets were approximately $25 million as of December 31,
1997 and have been at that asset level since  approximately  December  31, 1994.
The Board  believes  that those  distribution  fees could be used to promote the
Fund and the new Sub-Adviser and potentially to increase assets.  An increase in
net assets may afford the adviser  additional  flexibility in managing the Fund,
management of which is sometimes  complicated by its small asset size. Increased
assets also may ultimately  result in lower per share expenses for the Fund. The
Directors,  however,  considered  that the  immediate  effect  of the  Plan,  if
adopted,  would be an increase in Fund expenses in the amount of 0.25 percent of
the  Fund's  aggregate  net assets  attributable  to Class A shares on an annual
basis.  Class B shareholders  would be affected by the increase in expenses upon
converting to Class A shares. The Operating and Expense Table below reflects the
effect of the distribution fee on the Fund's expenses.

   After consideration of the potential benefits and detriments of the Plan, and
noting its continuing  duty to monitor the success of the Plan in attracting and
retaining Fund assets in connection  with the

                                       10


required  annual  consideration  of the Plan, the Board of Directors  determined
that  adoption  of the Plan was  reasonably  likely to benefit  the Fund and its
shareholders.

                                 PROPOSAL NO. 5
                APPROVAL OF AN AMENDMENT TO THE ADVISORY CONTRACT

   
   NOTE: CONSIDERATION OF PROPOSAL NO. 5 IS CONTINGENT UPON STOCKHOLDER APPROVAL
OF PROPOSAL NO. 4. IF PROPOSAL  NO. 4 IS NOT  APPROVED BY CLASS A  STOCKHOLDERS,
PROPOSAL NO. 5 WILL NOT BE PRESENTED FOR  CONSIDERATION AT THE MEETING,  AND ANY
VOTES IN FAVOR OF PROPOSAL NO. 5 WILL BE NULL AND VOID WITH NO LEGAL EFFECT.
    

   The Board of  Directors  proposes to amend the  Advisory  Contract,  which is
discussed  under  "Existing  Investment  Advisory  Contract,"  page 3. Under the
Advisory Contract, the Investment Manager has agreed to reimburse the Fund or to
waive such  portion of its  compensation  as may be necessary to insure that the
Fund's total annual expenses do not exceed an amount equal to one percent of the
Fund's  average  daily net assets.  For  purposes of this expense  limit,  total
annual  expenses  do  not  include  brokerage  commissions,   interest,   taxes,
extraordinary expenses (such as litigation) and distribution fees paid under the
Fund's  Class B  Distribution  Plan.  The Board of  Directors  proposes  also to
exclude  fees paid under the Fund's  proposed  Class A  Distribution  Plan.  The
combined  effect of this  amendment,  if  approved,  and adoption of the Class A
Distribution Plan would be to increase the Fund's total expenses by 0.25 percent
of the Fund's average daily net assets  attributable to its Class A shares.  See
the "Transaction and Operating Expense Table" above.

   The Board of Directors  determined that amendment of the Advisory  Contract's
expense limit was appropriate in light of its  recommendation of approval of the
Class A Distribution Plan. The Directors  considered that the expense limitation
was imposed originally to limit the level of the Fund's operating expenses,  and
that the expense of a  Distribution  Plan was not  contemplated  in setting that
limit.  The  Advisory  Contract is proposed to be amended by deleting  paragraph
5.(b) and replacing it with the following (new language is underlined):

   For  each  of the  Fund's  full  fiscal  years  during  the  term  of this
   Agreement,  the Management  Company  guarantees that the aggregate  annual
   expenses  of  every   character   (exclusive   of   interest   and  taxes,
   extraordinary  expenses (such as litigation),  and distribution  fees paid
   under the Fund's CLASS A AND Class B Distribution  PlanS, but inclusive of
   the  Management  Company's  compensation,  incurred  by the Fund shall not
   exceed an amount  equal to one  percent of the  average  net assets of the
   Fund for the year, such net assets to be calculated on a daily basis.  The
   Management  Company agrees,  on a monthly basis, to contribute to the Fund
   such funds or to waive  such  portion  of its fee as may be  necessary  to
   insure that such aggregate annual expenses will not exceed said amount. If
   this Agreement  shall be effective for only a portion of one of the Fund's
   fiscal years,  then the maximum annual expenses shall be prorated for such
   portion.  Brokerage fees and  commissions  incurred in connection with the
   purchase or sale of any  securities  by the Fund shall not be deemed to be
   expenses within the meaning of this paragraph (b).

   
   THE BOARD OR  DIRECTORS  RECOMMENDS  THAT THE  FUND'S  STOCKHOLDERS  VOTE FOR
APPROVAL OF THE AMENDMENT OF THE ADVISORY CONTRACT.

                             SUB-ADVISORY AGREEMENT


   THIS  AGREEMENT is made and entered  into on this ____ day of February,  1998
between  SECURITY  MANAGEMENT  COMPANY,  LLC (the  "Adviser"),  a Kansas limited
liability  company,  registered  under the  Investment  Advisers Act of 1940, as
amended (the  "Investment  Advisers Act"), and SALOMON BROTHERS ASSET MANAGEMENT
INC. (the "Subadviser"),  a New York corporation registered under the Investment
Advisers Act.

                                   WITNESSETH:

   WHEREAS,  Security  Tax-Exempt Fund (the "Fund"),  a Kansas  corporation,  is
registered with the Securities and Exchange  Commission (the "Commission") as an
open-end management investment company under the Investment Company Act of 1940,
as amended (the "Investment Company Act");

   WHEREAS,  the Fund has,  pursuant to an Advisory  Agreement  with the Adviser
(the "Advisory  Agreement"),  retained the Adviser to act as investment  adviser
for and to manage its assets;

   WHEREAS,  the Advisory  Agreement  permits the Adviser to delegate certain of
its duties under the Advisory Agreement to other investment advisers, subject to
the requirements of the Investment Company Act; and

   WHEREAS,  the Adviser  desires to retain the Subadviser as subadviser for the
Fund to act as investment  adviser for and to manage the Fund's  Investments (as
defined below) and the Subadviser desires to render such services.

   NOW,  THEREFORE,  the Adviser and Subadviser do mutually agree and promise as
follows:

   1.  APPOINTMENT AS  SUBADVISER.  The Adviser hereby retains the Subadviser to
act as investment  adviser for and to manage  certain assets of the Fund subject
to the  supervision  of the Adviser and the Board of  Directors  of the Fund and
subject to the terms of this Agreement;  and the Subadviser  hereby accepts such
employment. In such capacity, the Subadviser shall be responsible for the Fund's
Investments.

   2. DUTIES OF SUBADVISER.

      (a)  INVESTMENTS.  The  Subadviser is hereby  authorized  and directed and
   hereby agrees,  subject to the stated investment policies and restrictions of
   the  Fund  as set  forth  in  its  prospectus  and  statement  of  additional
   information as currently in effect and as  supplemented  or amended from time
   to time  (collectively  referred  to  hereinafter  as the  "Prospectus")  and
   subject to the  directions  of the Adviser and the Fund's  Board to purchase,
   hold  and  sell  investments  for  the  account  of  the  Fund   (hereinafter
   "Investments")  and to monitor on a continuous  basis the performance of such
   Investments.  The  Subadviser  shall  give the Fund the  benefit  of its best
   efforts in rendering its services as Subadviser.  The Subadviser may contract
   with or consult with such banks,  other  securities  firms,  brokers or other
   parties,  without  additional expense to the



   Fund, as it may deem appropriate  regarding  investment advice,  research and
   statistical data, clerical assistance or otherwise.

      (b) BROKERAGE. The Subadviser is authorized, subject to the supervision of
   the Adviser and the Fund's Board to establish and maintain accounts on behalf
   of the Fund with,  and place  orders for the  purchase and sale of the Fund's
   Investments with or through,  such persons,  brokers or dealers as Subadviser
   may select and negotiate  commissions  to be paid on such  transactions.  The
   Subadviser agrees that in placing such orders it shall attempt to obtain best
   execution,  provided  that,  the  Subadviser  may, on behalf of the Fund, pay
   brokerage  commissions  to a broker  which  provides  brokerage  and research
   services to the  Subadviser in excess of the amount another broker would have
   charged for effecting the transaction, provided (i) the Subadviser determines
   in good faith that the amount is  reasonable  in relation to the value of the
   brokerage and research  services provided by the executing broker in terms of
   the  particular   transaction  or  in  terms  of  the  Subadviser's   overall
   responsibilities  with  respect to the Fund and the  accounts as to which the
   Subadviser  exercises  investment  discretion,  (ii) such  payment is made in
   compliance  with Section  28(e) of the  Securities  Exchange Act of 1934,  as
   amended,  and any other  applicable  laws and  regulations,  and (iii) in the
   opinion of the  Subadviser,  the total  commissions  paid by the Fund will be
   reasonable  in relation to the benefits to the Fund over the long term. It is
   recognized  that the  services  provided by such brokers may be useful to the
   Subadviser in connection with the Subadviser's  services to other clients. On
   occasions when the Subadviser  deems the purchase or sale of a security to be
   in the best  interests of a Fund as well as other clients of the  Subadviser,
   the Subadviser,  to the extent  permitted by applicable laws and regulations,
   may, but shall be under no obligation to, aggregate the securities to be sold
   or purchased in order to obtain the most favorable  price or lower  brokerage
   commissions and efficient execution.  In such event, allocation of securities
   so sold or purchased,  as well as the expenses  incurred in the  transaction,
   will be made by the Subadviser in the manner the  Subadviser  considers to be
   the most equitable and consistent with its fiduciary  obligations to the Fund
   and to such other clients.  The Subadviser will report on such allocations at
   the  request of the  Adviser,  the Fund or the Fund's  Board  providing  such
   information as the number of aggregated trades to which the Fund was a party,
   the  broker(s)  to whom  such  trades  were  directed  and the  basis  of the
   allocation for the aggregated trades.

      (c) SECURITIES  TRANSACTIONS.  The Subadviser and any affiliated person of
   the Subadviser will not purchase securities or other instruments from or sell
   securities  or  other  instruments  to  a  Fund  ("Principal  Transactions");
   PROVIDED, HOWEVER, the Subadviser may enter into a Principal Transaction with
   a Fund if (i) the  transaction  is  permissible  under  applicable  laws  and
   regulations,  including,  without limitation,  the Investment Company Act and
   the  Investment  Advisers  Act  and the  rules  and  regulations  promulgated
   thereunder, and (ii) the transaction receives the express written approval of
   the Adviser.

          The Subadviser  agrees to observe and comply with Rule 17j-1 under the
   Investment  Company  Act and its Code of  Ethics,  as the same may be amended
   from time to time. The Subadviser  agrees to provide the Adviser and the Fund
   with a copy of such Code of Ethics.

                                       2


      (d) BOOKS AND RECORDS.  The Subadviser will maintain all books and records
   required  to be  maintained  pursuant to the  Investment  Company Act and the
   rules and  regulations  promulgated  thereunder  with respect to transactions
   made by it on behalf of the Fund including, without limitation, the books and
   records required by Subsections (b)(1), (5), (6), (7), (9), (10) and (11) and
   Subsection  (f) of Rule  31a-1  under the  Investment  Company  Act and shall
   timely furnish to the Adviser all  information  relating to the  Subadviser's
   services hereunder needed by the Adviser to keep such other books and records
   of the Fund  required by Rule 31a-1 under the  Investment  Company  Act.  The
   Subadviser  will also  preserve  all such books and  records  for the periods
   prescribed  in Rule 31a-2 under the  Investment  Company Act, and agrees that
   such books and records  shall remain the sole  property of the Fund and shall
   be immediately  surrendered to the Fund upon request.  The Subadviser further
   agrees  that  all  books  and  records  maintained  hereunder  shall  be made
   available  to the Fund or the  Adviser at any time upon  reasonable  request,
   including telecopy, during any business day.

      (e) INFORMATION CONCERNING  INVESTMENTS AND SUBADVISER.  From time to time
   as the  Adviser or the Fund may  request,  the  Subadviser  will  furnish the
   requesting party reports on portfolio transactions and reports on Investments
   held in the  portfolio,  all in such  detail as the  Adviser  or the Fund may
   reasonably  request.  The  Subadviser  will make  available  its officers and
   employees to meet with the Fund's Board of Directors at the Fund's  principal
   place of business on due notice to review the Investments of the Fund.

          The  Subadviser  will also  provide such  information  or perform such
   additional  acts as are  customarily  performed  by a  subadviser  and may be
   required  for  the  Fund or the  Adviser  to  comply  with  their  respective
   obligations  under  applicable  laws,  including,   without  limitation,  the
   Internal  Revenue  Code of 1986,  as amended  (the  "Code"),  the  Investment
   Company Act, the  Investment  Advisers  Act, the  Securities  Act of 1933, as
   amended (the "Securities Act") and any state securities laws, and any rule or
   regulation thereunder.

      (f)  CUSTODY  ARRANGEMENTS.   The  Subadviser  shall  provide  the  Fund's
   custodian, on each business day with information relating to all transactions
   concerning the Fund's assets.

      (g)  COMPLIANCE  WITH  APPLICABLE  LAWS AND  GOVERNING  DOCUMENTS.  In all
   matters relating to the performance of this Agreement, the Subadviser and its
   directors,  officers, partners, employees and interested persons shall act in
   conformity with the Fund's Articles of Incorporation,  By-Laws, and currently
   effective  registration  statement  and with  the  written  instructions  and
   directions  of the Fund's  Board and the  Adviser,  and shall comply with the
   requirements of the Investment Company Act, the Investment  Advisers Act, the
   Commodity  Exchange  Act,  the rules  thereunder,  and all  other  applicable
   federal and state laws and regulations.

          In carrying out its obligations  under this Agreement,  the Subadviser
   shall  ensure  that  the  Fund  complies  with all  applicable  statutes  and
   regulations  necessary to qualify the Fund as a Regulated  Investment Company
   under Subchapter M of the Code (or any successor provision), and shall notify
   the Adviser immediately upon having a reasonable basis for believing that the
   Fund has ceased to so qualify or that it might not so qualify in the future.

                                       3


          The Adviser has  furnished the  Subadviser  with copies of each of the
   following  documents and will furnish the Subadviser at its principal  office
   all future  amendments and supplements to such documents,  if any, as soon as
   practicable  after such  documents  become  available:  (i) the  Articles  of
   Incorporation  of the Fund, (ii) the By-Laws of the Fund and (iii) the Fund's
   registration  statement  under the Investment  Company Act and the Securities
   Act of 1933, as amended, as filed with the Commission.

      (h) VOTING OF PROXIES. The Subadviser shall direct the custodian as to how
   to vote such proxies as may be necessary or advisable in connection  with any
   matters submitted to a vote of shareholders of securities held by the Fund.

   3. INDEPENDENT  CONTRACTOR.  In the performance of its duties hereunder,  the
Subadviser  is and  shall be an  independent  contractor  and  unless  otherwise
expressly  provided  herein or otherwise  authorized  in writing,  shall have no
authority  to act  for or  represent  the  Fund  or the  Adviser  in any  way or
otherwise be deemed an agent of the Fund or the Adviser.

   4.  COMPENSATION.  The Adviser shall pay to the Subadviser,  for the services
rendered  hereunder,  an annual fee equal to 0.22  percent of the average  daily
closing  value of the net  assets of the  Fund,  computed  on a daily  basis and
payable  monthly.  If this Agreement  shall be effective for only a portion of a
year,  then the  Subadviser's  compensation  for said year shall be prorated for
such portion.  For purposes of this  paragraph 4, the value of the net assets of
the Fund shall be computed in the same manner at the end of the  business day as
the value of such net assets is computed in connection with the determination of
the net asset value of the Fund's shares as described in the Fund's  Prospectus.
Payment of the  Subadviser's  compensation for the preceding month shall be made
as promptly as possible after the end of each month.

   5.  EXPENSES.  The  Subadviser  shall  bear all  expenses  incurred  by it in
connection  with its services under this Agreement and will,  from time to time,
at its sole expense employ or associate  itself with such persons as it believes
to be particularly fitted to assist it in the execution of its duties hereunder.

                                    EXHIBIT B

                            SECURITY TAX-EXEMPT FUND
                                     CLASS A
                                DISTRIBUTION PLAN

1.  THE PLAN. This Distribution Plan (the "Plan"), provides for the financing by
    Security  Tax-Exempt  Fund (the "Fund") of  activities  which are, or may be
    deemed to be, primarily  intended to result in the sale of class A shares of
    the  Fund  (hereinafter  called  "distribution-related   activities").   The
    principal  purpose  of  this  Plan  is to  enable  the  Fund  to  supplement
    expenditures by Security  Distributors,  Inc., the Distributor of its shares
    (the  "Distributor")  for  distribution-related  activities.  This  Plan  is
    intended to comply with the  requirements  of Rule 12b-1 (the "Rule")  under
    the Investment Company Act of 1940 (the "1940 Act").

    The Board of Directors, in considering whether the Fund should implement the
    Plan, has requested and evaluated such information as it deemed necessary to
    make an informed  determination as to whether the Plan should be implemented
    and has considered such pertinent factors as it deemed necessary to form the
    basis for a decision to use assets of the Fund for such purposes.

    In voting to approve the  implementation  of the Plan,  the  Directors  have
    concluded,  in the  exercise of their  reasonable  business  judgment and in
    light of their  respective  fiduciary  duties,  that  there is a  reasonable
    likelihood that the Plan will benefit the Fund and its shareholders.

2.  COVERED EXPENSES.

    (a)  The Fund may make payments  under this Plan, or any agreement  relating
         to the  implementation  of this Plan, in connection with any activities
         or expenses  primarily intended to result in the sale of class A shares
         of  the  Fund,   including,   but  not   limited   to,  the   following
         distribution-related activities:

         (i)    Preparation,  printing and  distribution  of the  Prospectus and
                Statement of Additional  Information and any supplement  thereto
                used in connection with the offering of the Fund's shares to the
                public;

         (ii)   Printing  of  additional  copies for use by the  Distributor  as
                sales literature, of reports and other communications which were
                prepared by the Fund for distribution to existing shareholders;

         (iii)  Preparation,  printing  and  distribution  of  any  other  sales
                literature  used in  connection  with the offering of the Fund's
                shares to the public;

         (iv)   Expenses  incurred in advertising,  promoting and selling shares
                of the Fund to the public;



         (v)    Any fees paid by the Distributor to securities  dealers who have
                executed a Dealer's Distribution  Agreement with the Distributor
                for account  maintenance and personal service to shareholders of
                the Fund (a "Service Fee");

         (vi)   Commissions  to sales  personnel for selling  shares of the Fund
                and interest expenses related thereto; and

         (vii)  Expenses  incurred in  promoting  sales of shares of the Fund by
                securities  dealers,  including  the  costs  of  preparation  of
                materials  for   presentations,   travel   expenses,   costs  of
                entertainment,  and other expenses  incurred in connection  with
                promoting sales of Fund shares by dealers.

    (b)  Any payments for distribution-related activities shall be made pursuant
         to an agreement.  As required by the Rule,  each agreement  relating to
         the  implementation  of this Plan  shall be in writing  and  subject to
         approval and  termination  pursuant to the  provisions  of Section 7 of
         this Plan. However,  this Plan shall not obligate the Fund or any other
         party to enter into such agreement.

3.  AGREEMENT WITH DISTRIBUTOR. All payments to the Distributor pursuant to this
    Plan shall be subject to and be made in compliance with a written  agreement
    between  the  Fund  and the  Distributor  containing  a  provision  that the
    Distributor  shall furnish the Fund with  quarterly  written  reports of the
    amounts expended and the purposes for which such expenditures were made, and
    such  other  information  relating  to  such  expenditures  or to the  other
    distribution-related  activities  undertaken or proposed to be undertaken by
    the  Distributor  during such fiscal year under its  Distribution  Agreement
    with the Fund as the Fund may reasonably request.

4.  DEALER'S DISTRIBUTION  AGREEMENT.  The Dealer's Distribution  Agreement (the
    "Agreement")  contemplated  by Section 2(a)(v) above shall permit payment of
    Service Fees to  securities  dealers by the  Distributor  only in accordance
    with the  provisions  of this  paragraph  and shall have the approval of the
    majority of the Board of Directors of the Fund,  including  the  affirmative
    vote of a majority of those Directors who are not interested  persons of the
    Fund and who have no direct or indirect  financial interest in the operation
    of the Plan or any agreement related to the Plan ("Independent  Directors"),
    as required by the Rule. The  Distributor  may pay to the other party to any
    such  Agreement  a  Service  Fee for  distribution  and  marketing  services
    provided by such other party.  Such Service Fee shall be payable (a) for the
    first year,  initially,  in an amount  equal to .25 percent  annually of the
    aggregate  net asset  value of the shares  purchased  by such other  party's
    customers  or  clients,  and (b) for each  year  thereafter,  quarterly,  in
    arrears  in an amount  equal to such  percentage  (not in excess of  .000685
    percent per day or .25 percent annually) of the aggregate net asset value of
    the shares held by such other  party's  customers or clients at the close of
    business each day as determined  from time to time by the  Distributor.  The
    distribution and marketing services  contemplated hereby shall include,  but
    are  not  limited  to,  answering  inquiries  regarding  the  Fund,  account
    designations and addresses, maintaining the investment of such other party's
    customers or clients in the Fund and similar  services.  In determining  the
    extent of such other

                                       2


    party's  assistance  in  maintaining  such  investment  by its  customers or
    clients,  the  Distributor  may take into account the  possibility  that the
    shares held by such  customer or client  would be redeemed in the absence of
    such fee.

5.  LIMITATIONS  ON  COVERED  EXPENSES.  The basic  limitation  on the  expenses
    incurred by the Fund under Section 2 of this Plan  (including  Service Fees)
    in any fiscal year of the Fund shall be one-quarter of one percent (.25%) of
    the Fund's average daily net assets for such fiscal year. The payments to be
    paid  pursuant to this Plan shall be  calculated  and accrued daily and paid
    monthly or at such other intervals as the Directors shall determine, subject
    to any applicable  restriction imposed by rules of the National  Association
    of Securities Dealers, Inc.

6.  INDEPENDENT  DIRECTORS.  While this Plan is in  effect,  the  selection  and
    nomination  of  Independent  Directors of the Fund shall be committed to the
    discretion of the  Independent  Directors.  Nothing herein shall prevent the
    involvement of others in such selection and nomination if the final decision
    on any such  selection  and  nomination  is  approved  by a majority  of the
    Independent Directors.

7.  EFFECTIVENESS,  CONTINUATION,  TERMINATION AND AMENDMENT. This Plan and each
    Agreement  relating to the  implementation of this Plan shall go into effect
    when approved.

    (a)  By vote of the Fund's  Directors,  including the affirmative  vote of a
         majority  of the  Independent  Directors,  cast in  person at a meeting
         called for the purpose of voting on the Plan or the Agreement;

   
    (b)  By a vote of holders of at least a majority of the  outstanding  voting
         securities  of each of the  Class A shares  and  Class B shares  of the
         Fund; and
    

    (c)  Upon the  effectiveness  of an  amendment  to the  Fund's  registration
         statement, reflecting this Plan, filed with the Securities and Exchange
         Commission under the Securities Act of 1933.

    This Plan and any  Agreements  relating to the  implementation  of this Plan
    shall,  unless terminated as hereinafter  provided,  continue in effect from
    year to year only so long as such  continuance is  specifically  approved at
    least annually by vote of the Fund's  Directors,  including the  affirmative
    vote of a majority of its Independent Directors, cast in person at a meeting
    called  for the  purpose  of voting on such  continuance.  This Plan and any
    Agreements relating to the implementation of this Plan may be terminated, in
    the case of the Plan, at any time or, in the case of any agreements upon not
    more  than  sixty  (60)  days'  written  notice  to any  other  party to the
    Agreement by vote of a majority of the Independent  Directors or by the vote
    of the holders of a majority of the  outstanding  voting  securities  of the
    Class A shares of the Fund. Any Agreement  relating to the implementation of
    this Plan shall  terminate  automatically  in the event it is assigned.  Any
    material amendment to this Plan shall require approval by vote of the Fund's
    Directors,  including the affirmative  vote of a majority of the Independent
    Directors,  cast in person at a meeting  called for the purpose of voting on
    such amendment and, if such amendment  materially  increases the limitations
    on expenses payable

                                       3


   
    under the Plan,  it shall also  require  approval by a vote of holders of at
    least a  majority  of the  outstanding  voting  securities  of each class of
    shares of the Fund for approval  with  respect to that class.  As applied to
    the  respective  classes of shares of the Fund the phrase  "majority  of the
    outstanding  voting  securities" shall have the meaning specified in Section
    2(a) of the 1940 Act. The  provisions of the Plan are severable with respect
    to each class of shares offered by the Fund.
    

    In the event this Plan should be terminated by the shareholders or Directors
    of the Fund, the payments paid to the Distributor pursuant to the Plan up to
    the date of termination  shall be retained by the Distributor.  Any expenses
    incurred by the  Distributor  in excess of those  payments  will be the sole
    responsibility of the Distributor.

8.  RECORDS.  The Fund  shall  preserve  copies  of this  Plan  and any  related
    Agreements  and all reports made pursuant to Section 3 hereof,  for a period
    of not less than six (6)  years  from the date of this  Plan,  the first two
    years in an easily accessible place.
