Item 27.  Indemnification.

          A policy of insurance covering Security Management Company, its
          subsidiary (Security Distributors, Inc.), and all of the registered
          investment companies advised by Security Management Company insures
          the Registrant's directors and officers against liability arising by
          reason of an alleged breach of duty caused by any negligent act,
          error or accidental omission in the scope of their duties.

          Paragraph 23 of the Registrant's Bylaws, as amended March 23, 1979,
          provides in relevant part as follows:

               23-A.  Indemnification.  The corporation shall indemnify every
               person who is or was a director or officer of the corporation,
               or is or was serving at the request of the corporation as a
               director or officer of another corporation, to the full extent
               permitted or authorized by the laws of the State of Kansas, as
               now in effect and as hereafter amended, against any liability,
               judgment, fine, amount paid in settlement, cost or expense
               (including attorneys' fees) asserted or threatened against and
               incurred by such person in his capacity as or arising out of his
               status as a director or officer of the corporation or, if
               serving at the request of the corporation, as a director or
               officer of another corporation; provided, however, that the
               corporation shall not indemnify any person if such action would
               be in violation of the provisions of the Investment Company Act
               of 1940.  The indemnification provided by this bylaw provision
               shall not be exclusive of any other rights to which those
               indemnified may be entitled under any other bylaw or under any
               agreement, and shall not limit in any way any right which the
               corporation may have to make different or further
               indemnifications which respect to the same or different persons
               or classes of persons.

          recommendation that the Articles of Incorporation be amended by
          adopting the following Article Fifteenth:

               to its stockholders for monetary damages for breach of fiduciary
               duty as a director, provided that this sentence shall not
               eliminate nor limit the liability of a director:

               A.   for any breach of his or her duty of loyalty to the
                    corporation or to its stockholders; 
               B.   for acts or omissions not in good faith or which involve 
                    intentional misconduct or a knowing violation of law; 
               C.   for any unlawful dividend, stock purchase or redemption 
                    under the provisions of Kansas Statutes Annotated (K.S.A.)
                    17-6424 and amendments thereto; or
               D.   for any transaction from which the director derived an
                    improper personal benefit."

       office and the name of the registered agent of the Corporation in the
       State of Kansas shall be as stated in the Articles of Incorporation or
       as shall be determined from time the time by the Board of Directors and
       on file in the appropriate public offices of the State of Kansas
       pursuant to applicable provisions of law.

  2.   Corporate Offices.  The Corporation may have such other corporate

  4.   Stockholders' Right of Inspection.  A stockholder of record, upon
       written demand to inspect the records of the Corporation pursuant to any
       statutory or other legal right, shall be privileged to inspect such

       competitor or prospective competitor of the Corporation.  The
       Corporation as a condition precedent to any stockholder's inspection of
       the records of the Corporation may require the stockholder to indemnify
       the Corporation, in such manner and for such amount as may be determined
       by the Board of Directors, against any loss or damage which may be
       suffered by it arising out of or resulting from any unauthorized
       disclosure made or permitted to be made by such stockholder of
       information obtained in the course of such inspection.

 10.   Registered Stockholders - Exceptions - Stock Ownership Presumed.  The
       Corporation shall be entitled to treat the holders of the shares of
       stock of the Corporation, as recorded on the stock record or transfer
       books of the Corporation, as the holders of record and as the holders
       and owners in fact thereof and, accordingly, the Corporation shall not
       be required to recognize any equitable or other claim to or interest in
       any such shares on the part of any other person or other claim to or
       interest in any such shares on the part of any other person, firm,
       partnership, corporation or association, whether or not the Corporation
       shall have express or other notice thereof, except as is otherwise
       expressly required by law, and the term "stockholder" as used in these
       Bylaws means one who is a holder of record of shares of the Corporation;
       provided, however, that if permitted by law,

       (a)   shares standing in the name of another corporation, domestic or
             foreign, may be voted by such officer, agent or proxy as the
             Bylaws of such corporation may prescribe, or, in the absence of
             such provision, as the Board of Directors of such corporation may
             determine;

       (b)   shares held by a person in a fiduciary capacity may be voted by
             such person; and,

       (c)   a stockholder whose shares are pledged shall be entitled to vote
             such shares, unless in the transfer of the shares by the pledgor
             on the books of the Corporation, he/she shall have expressly
             empowered the pledgee to vote thereon, in which case only the
             pledgee or his/her proxy may represent said stock and vote
             thereon.

 11.   Consent of Stockholders in Lieu of Meeting. To the extent, if any, and
       in the manner permitted by statute and unless otherwise provided in the
       Articles of Incorporation, any action required to be taken at any annual
       or special meeting of stockholders of the Corporation, or any action
       which may be taken at any annual or special meeting of such
       stockholders, may be taken by written consent without a meeting.

 12.   Waiver of Notice.  Whenever any notice is required to be given under the
       provisions of these Bylaws, the Articles of Incorporation of the
       Corporation, or of any law, a waiver thereof, if not expressly
       prohibited by law, in writing signed by the person or persons entitled
       to notice shall, whether before or after the time stated therein, be
       deemed the equivalent to the giving of such notice.  Attendance of a
       person at a meeting shall constitute a waiver of notice of such meeting,
       except when a person attends a meeting for the express purpose of
       objecting at the beginning of the meeting, to the transaction of any
       business because the meeting is not lawfully called or convened.

 13.   Quorum.  Except as otherwise may be provided by law, by the Articles of
       Incorporation of the Corporation or by these Bylaws, the holders of a
       majority of the stock issued and outstanding and entitled to vote
       thereat, present in person or represented by proxy, shall be required
       for and shall constitute a quorum at all meetings of the stockholders
       for the transaction of any business.  Every decision of a majority in
       amount of shares of such





                                      3
<PAGE>   4

       quorum shall be valid as a corporate act, except in those specific
       instances in which a larger vote is required by law or by the Articles
       of Incorporation or by these Bylaws.

       If a quorum be not present at any meeting, the stockholders entitled to
       vote thereat, present in person or by proxy, shall have power to adjourn
       the meeting from time to time without notice other than announcement at
       the meeting, until the requisite amount of voting stock shall be
       present. If the adjournment is for more than thirty (30) days, or if
       after adjournment a new record date is fixed for the adjourned meeting,
       a notice of the adjourned meeting shall be given to each stockholder of
       record entitled to vote at the meeting. At any subsequent session of the
       meeting at which a quorum is present in person or by proxy any business
       may be transacted which could have been transacted at the initial
       session of the meeting if a quorum had been present.

 14.   Proxies.  At any meeting of the stockholders, every stockholder having
       the right to vote shall be entitled to vote in person or by proxy
       executed by an instrument in writing subscribed by such a stockholder
       and bearing a date not more than three (3) years prior to said meeting
       unless said instrument provides that it shall be valid for a longer
       period.

 15.   Voting.  Each stockholder shall have one vote for each share of stock
       having voting power registered in his/her name on the books of the
       Corporation and except where the transfer books of the Corporation shall
       have been closed or a date shall have been fixed as a record date for
       the determination of its stockholders entitled to vote, no share of
       stock shall be voted at any election for directors which shall have been
       transferred on the books of the Corporation within twenty (20) days next
       preceding such election of Directors.  At all elections of Directors,
       cumulative voting shall prevail, so that each stockholder shall be
       entitled to as many votes as shall equal the number of his/her shares of
       stock multiplied by the number of Directors to be elected, and he/she
       may cast all of such votes for a single Director or may distribute them
       among the number to be voted for, or any two or more as he/she sees fit.
       Voting shall be ballot for the election of Directors and on such matters
       as may be required by law, provided that voting by ballot on any matter
       may be waived by the unanimous consent of those stockholders entitled to
       vote present at the meeting.  A stockholder holding stock in a fiduciary
       capacity shall be entitled to vote the shares so held, and a stockholder
       whose stock is pledged shall be entitled to vote unless, in the transfer
       by the pledgor on the books of the Corporation, (s)he shall have
       expressly empowered the pledgee to vote thereon, in which case only the
       pledgee or his/her proxy may represent said stock and vote thereon.

 16.   Stockholders' Lists.  A complete list of the stockholders entitled to
       vote at every election of Directors, arranged in alphabetical order,
       with the address of and the number of voting shares held by each
       stockholder, shall be prepared by the officer having charge of the stock
       books of the Corporation and for at least ten (10) days prior to the
       date of the election shall be open at the place where the election is to
       be held, during the usual hours for business, to the examination of any
       stockholder and shall be produced and kept open at the place of the
       election during the whole time thereof for the inspection of any
       stockholder present.  The original or duplicate stock ledger shall be
       the only evidence as to who are stockholders





                                      4
<PAGE>   5

       entitled to examine such lists, or the books of the Corporation, or to
       vote in person or by proxy, at such election.  Failure to comply with
       the foregoing shall not affect the validity or any action taken at any
       such meeting.

 17.   Presiding Officials.  Every meeting of the stockholders, for whatever
       object, shall be convened by the President, or by the officer or person
       who called the meeting by notice as above provided, but it shall be
       presided over by the officers specified in paragraphs 37 and 38 of these
       Bylaws; provided, however, that the stockholders at any meeting, by a
       majority vote in amount of shares represented thereat, and
       notwithstanding anything to the contrary contained elsewhere in these
       Bylaws, may select any persons of their choosing to act as Chairman and
       Secretary of such meeting or any session thereof.

       particular place) at such place or places within or without the State of
       Kansas as the Board of Directors may from time to time determine.

 19.   Management.  The management of all affairs, property and business of the
       corporation shall be vested in a Board of Directors, consisting of a

       regardless of whether or not the time and place of such meeting shall be
       suggested or provided for by resolution of the stockholders, at such
       time and place as shall be consented to in writing by all of the newly
       elected Directors.

       Every Director of the Corporation, upon his/her election, shall qualify
       by accepting the office of the Director, and his/her attendance at, or

       meeting without any notice thereof having been given if all Directors
       shall be present.

 25.   Meetings by Conference Telephone or Similar Communications Equipment.
       Unless otherwise restricted by law, the Articles of Incorporation or
       these Bylaws, members of the Board of Directors of the Corporation, or
       any committee designated by the board, may

<PAGE>   7

       of Incorporation or these Bylaws, the act of a majority of the Directors
       present at any meeting at which there is a quorum shall be the act of
       the Board of Directors.

       If at least two (2) Directors or one-third (1/3) of the whole Board of
       Directors, whichever is greater, is present at any meeting at which a
       quorum is not present, a majority of the Directors present at such
       meeting shall have power successively to adjourn the meeting from time
       to time to a subsequent date, without notice to any Directors other than
       announcement at the meeting.  At such adjourned meeting at which a
       quorum is present, any business may be transacted which might have been
       transacted at the original meeting with was adjourned.

 27.   Standing or Temporary Committees.  The Board of Directors may, by
       resolution or resolutions passed by a majority of the whole Board,
       designate one (1) or more committees, each committee to consist of one
       (1) or more Directors of the Corporation.  The Board may designate one
       (1) or more Directors as alternate members of any committee, who may
       replace any absent or disqualified member at any meeting of the
       committee.  In the absence or disqualification of a member of a
       committee, the member or members thereof present at any meeting and not
       disqualified from voting, whether or not he/she or they constitute a
       quorum, may unanimously appoint another member of the Board of Directors
       to act at the meeting in the place of any such absent or disqualified
       member.  Any such committee, to the extent provided in the resolution of
       the Board of Directors or in these Bylaws, shall have and may exercise
       all of the powers and authority of the Board of Directors in the
       management of the business and affairs of the Corporation, and may
       authorize the seal of the Corporation to be affixed to all papers which
       may require it; but no such committee shall have the power of authority
       of the Board of Directors with respect to amending the Articles of
       Incorporation, adopting an agreement of merger or consolidation,
       recommending to the stockholders the sale, lease or exchange of all or
       substantially all of the Corporation's property and assets, recommending
       to the stockholders a dissolution of the Corporation or a revocation of
       a dissolution, or amending the Bylaws of the Corporation; and, unless
       the resolution, these Bylaws or the Articles of Incorporation expressly
       so provide, no such committee shall have power or authority to declare a
       dividend or to authorize the issuance of stock.

       Such committee or committees shall have such name or names as may be
       determined from time to time by resolution adopted by the Board of
       Directors.  All committees so appointed shall, unless otherwise provided
       by the Board of Directors, keep regular minutes of the transactions at
       their meetings and shall cause them to be recorded in books kept for
       that





                                      7
<PAGE>   8

       purpose in the office of the Corporation and shall report the same to
       the Board of Directors at its next meeting.  The Secretary or an
       Assistant Secretary of the Corporation may act as Secretary of the
       committee if the committee so requests.

 28.   Compensation.  Unless otherwise restricted by the Articles of
       Incorporation, the Board of Directors may, by resolution, fix the
       compensation to be paid Directors for serving as Directors of the
       Corporation and may, by resolution, fix a sum which shall be allowed and
       paid for attendance at each meeting of the Board of Directors and may
       provide for reimbursement of expenses incurred by Directors in attending
       each meeting; provided that nothing herein contained shall be construed
       to preclude any Director from serving the Corporation in any other
       capacity and receiving his/her regular compensation therefor.  Members
       of special or standing committees may be allowed similar compensation
       for attending committee meetings.  Nothing herein contained shall be
       construed to preclude any Director or committee member from serving the
       Corporation in any other capacity and receiving compensation therefor.

 29.   Resignations.  Any Director may resign at any time upon written notice
       to the Corporation.  Such resignation shall take effect at the time
       specified therein or shall take effect upon receipt thereof  by the
       Corporation if no time is specified therein, and unless otherwise
       specified therein, the acceptance of such resignation shall not be
       necessary to make it effective.

 30.   Indemnification and Liability of Directors and Officers.  Each person
       who is or was a Director or officer of the Corporation or is or was
       serving at the request of the Corporation as a Director or officer of
       another corporation (including the heirs, executors, administrators and
       estate of such person) shall be indemnified by the Corporation as of
       right to the full extent permitted or authorized by the laws of the
       State of Kansas, as now in effect and is hereafter amended, against any
       liability, judgment, fine, amount paid in settlement, cost and expense
       (including attorneys' fees) asserted or threatened against and incurred
       by such person in his/her capacity as or arising out of his/her status
       as a Director or officer of the Corporation or, if serving at the
       request of the Corporation, as a Director or officer of another
       corporation.  The indemnification provided by this bylaw provision shall
       not be exclusive of any other rights to which those indemnified may be
       entitled under the Articles of Incorporation, under any other bylaw or
       under any agreement, vote of stockholders or disinterested directors or
       otherwise, and shall not limit in any way any right which the
       Corporation may have to make different or further indemnification with
       respect to the same or different persons or classes of persons.

       No person shall be liable to the Corporation for any loss, damage,
       liability or expense suffered by it on account of any action taken or
       omitted to be taken by him/her as a Director or officer of the
       Corporation or of any other corporation which he/she serves as a
       Director or officer at the request of the Corporation, if such person
       (a)  exercised the same degree of care and skill as a prudent man would
       have exercised under the circumstances in the conduct of his/her own
       affairs, or (b)  took or omitted to take such action in reliance upon
       advice of counsel for the Corporation, or for such other corporation, or
       upon





                                      8
<PAGE>   9

       statement made or information furnished by Directors, officers,
       employees or agents of the Corporation, or of such other corporation,
       which he/she had no reasonable grounds to disbelieve.

       In the event any provision of this section 30 shall be in violation of
       the Investment Company Act of 1940, as amended, or of the rules and
       regulations promulgated thereunder, such provisions shall be void to the
       extent of such violations.

 31.   Action Without a Meeting.  Unless otherwise restricted by the Articles
       of Incorporation or these Bylaws, any action required or permitted to be
       taken at any meeting of the Board of Directors or any committee thereof
       may be taken without a meeting if written consent thereto is signed by
       all members of the Board of Directors or of such committee, as the case
       may be, and such written consent is filed with the minutes of
       proceedings of the Board or committee.

 32.   Numbers and Powers of the Board. The property and business of this
       Corporation shall be managed by a Board of Directors, and the number of
       Directors to constitute the Board shall be not less than five (5) nor
       more than eight (8).  Directors need not be stockholders.  In addition
       to the powers and authorities by these Bylaws expressly conferred upon
       the Board of Directors, the Board may exercise all such powers of the
       corporation and do or cause to be done all such lawful acts and things
       as are not by statute or by the Articles of Incorporation or by these
       Bylaws prohibited, or required to be exercised or done by the
       stockholders only.

 33.   Term of Office.  The first Board of Directors shall be elected at the
       first duly held meeting of the incorporators and thereafter they shall
       be elected at the annual meetings of the stockholders.  Except as may
       otherwise be provided by law, the Articles of Incorporation or these
       Bylaws, each Director shall hold office until the next annual election
       and until a successor shall be duly elected and qualified, or until
       his/her written resignation shall have been filed with the Secretary of
       the Corporation.  Each Director, upon his/her election, shall qualify by
       accepting the office of Director by executing and filing with the
       Corporation a written acceptance of his/her election which shall be
       placed in the minute book.

 34.   Waiver.  Any notice provided or required to be given to the Directors
       may be waived in writing by any of them.  Attendance of a Director at
       any meeting shall constitute a waiver of notice of such meeting except
       where he/she attends for the express purpose of objecting to the
       transaction of any business thereat because the meeting is not lawfully
       called or convened.

                                    OFFICERS

 35.   (a)   Officers -- Who Shall Constitute.  The officers of the Corporation
             shall be a Chairman of the Board, a President, one or more Vice
             Presidents, a Secretary, a Treasurer, one or more Assistant
             Secretaries and one or more Assistant Treasurers.  The Board shall





                                      9
<PAGE>   10

             elect a President, a Secretary and a Treasurer at its first
             meeting after each annual meeting of the stockholders.  The Board
             then, or from time to time, may elect one or more of the other
             prescribed officers as it may deem advisable, but need not elect
             any officers other than a President, a Secretary and a Treasurer. 
             The Board may, if it desires, elect or appoint additional officers
             and may further identify or describe any one or more of the
             officers of the Corporation.  In the discretion of the Board of
             Directors, the office of Chairman of the Board of Directors may
             remain unfilled.  The Chairman of the Board of Directors, if any,
             shall at all times be, and other officers may be, members of the
             Board of Directors.

             Officers of the Corporation need not be members of the Board of
             Directors.  Any two (2) or more offices may be held by the same 
             person.

             An officer shall be deemed qualified when he/she enters upon the
             duties of the office to which he/she has been elected or appointed
             and furnishes any bond required by the Board; but the Board may
             also require his/her written acceptance and promise faithfully to
             discharge the duties of such office.

       (b)   Term of Office.  Each officer of the Corporation shall hold
             his/her office at the pleasure of the Board of Directors or for
             such other period as the Board may specify at the time of his/her
             election or appointment, or until his/her death, resignation or
             removal by the Board, whichever first occurs.  In any event, each
             officer of the Corporation who is not reelected or reappointed at
             the annual election of officers by the Board next succeeding
             his/her election or appointment shall be deemed to have been
             removed by the Board, unless the Board provides otherwise at the
             time of his/her election or appointment.

       (c)   Other Agents.  The Board from time to time may also appoint such
             other agents for the Corporation as it shall deem necessary or
             advisable, each of whom shall serve at the pleasure of the Board
             or for such period as the Board may specify, and shall exercise
             such powers, have such titles and perform such duties as shall be
             determined from time to time by the Board or by an officer
             empowered by the Board to make such determinations.

 36.   Chairman of the Board.  If a Chairman of the Board be elected, he/she
       shall preside at all meetings of the stockholders and Directors at which
       he/she may be present and shall have such other duties, powers and
       authority as any be prescribed elsewhere in these Bylaws.  The Board of
       Directors may delegate such other authority and assign such additional
       duties to the Chairman of the Board, other than those conferred by law
       exclusively upon the President, as it may from time to time determine,
       and, to the extent permissible by law, the Board may designate the
       Chairman of the Board as the Chief Executive Officer of the Corporation
       with all of the powers otherwise conferred upon the President of the
       Corporation under paragraph 37 of these Bylaws, or it may, from time to
       time, divide the responsibilities, duties and authority for the general
       control and management of the Corporation's business and affairs between
       the Chairman of the Board and the President.

       and he/she shall carry into effect all directions and resolutions of the
       Board.  The President, in the absence of the Chairman of the Board or if
       there be no Chairman of the Board, shall preside at all meetings of the

       instruments for and in the name of the Corporation.

       Unless the Board otherwise provides, the President, or any person
       designated in writing by him/her, shall have full power and authority on
       behalf of this Corporation (a)  to attend and vote or take action at any
       meeting of the holders of securities of corporations in which this
       Corporation may hold securities, and at such meetings shall possess and
       may exercise any and all rights and powers incident to being a holder of
       such securities, and (b)  to execute and deliver waivers of notice and
       proxies for and in the name of the Corporation with respect to any
       securities held by this Corporation.

       specifically delegated to him/her by the Board of Directors or are
       conferred by law exclusively upon him/her, and in the absence,

       It shall be the principal responsibility of the Secretary to give, or
       cause to be given, notice of all meetings of the stockholders and of the

       give such notice as is authorized elsewhere in these Bylaws.

       or duplicates, required to be maintained in Kansas, or elsewhere, are so

       and shall have authority to affix the seal to any instrument requiring a
       corporate seal and, when so affixed, he/she shall attest the seal by
       his/her signature.  The Board of Directors may give general authority to
       any other officer to affix the seal of the Corporation and to attest the
       affixing by his/her signature.

       The Secretary shall have the general duties, responsibilities and
       authorities of a Secretary of a Corporation and shall perform such other
       duties and have such other responsibility and authority as may be
       prescribed elsewhere in these Bylaws or from time to time by the Board
       of Directors or the Chief Executive Officer of the Corporation, under
       whose direct supervision (s)he shall be.

       In the absence of the Secretary or in the event of his/her disability,

       and shall render to the Chief Executive Officer of the Corporation and
       the Directors whenever they may require it, an account of all his/her
       transactions as Treasurer and of those under his/her jurisdiction, and
       of the financial condition of the Corporation.

       He/she shall perform such other duties and shall have such other
       responsibility and authority as may be prescribed elsewhere in these
       Bylaws or from time to time by the Board of Directors.

       Board, be the Chief Financial and Accounting Officer of the Corporation.

       If required by the Board, he/she shall give the Corporation a bond in a
       sum and with one or more sureties satisfactory to the Board, for the

       vouchers, money and other property of whatever kind in his/her
       possession or under his/her control which belong to the Corporation.

       of the functions, duties, powers and responsibilities of any officer to

       compensation of the Chairman of the Board and the President, may, unless
       prohibited by law, be delegated by the Board to the Chairman of the
       Board or the President, or may be delegated to a committee.  Salaries
       and compensation of all appointed officer, agents, and employees of the
       Corporation may be fixed, increased or decreased by the Board of
       Directors, but until action is taken with respect thereto by the Board
       of Directors the same fixed, increased or decreased by the Chairman of

       to obtaining and retaining for the Corporation the services of

 45.   Certificates for Shares of Stock.  Certificates for shares of stock
       shall be issued in numerical order, and each stockholder shall be

       by, the Chairman of the Board or the President or a Vice President, and
       by the Treasurer or an Assistant Treasurer or the Secretary or an
       Assistant Secretary, certifying the number of shares owned by him/her.
       To the extent permitted by statute, any of or all of the signatures on
       such certificate may be a facsimile.  In case any officer, transfer
       agent or registrar who has signed or whose facsimile signature has been
       placed upon a certificate shall have ceased to be such officer, transfer
       agent or registrar before such certificate is issued, such certificate
       may nevertheless be issued by the Corporation with the same effect as if
       such officer, transfer agent or registrar who signed such certificate,
       or whose facsimile signature shall have been used thereon, had not
       ceased to be such officer, transfer agent or registrar of the
       Corporation.

 46.   Transfers of Stock.  Transfers of stock shall be made only upon the
       transfer books of the Corporation, kept at the office of the Corporation
       or of the transfer agent designated to transfer the class of stock, and
       before a new certificate is issued the old certificate shall be
       surrendered for cancellation.  Until and unless the Board appoints some
       other person, firm or corporation as its transfer agent (and upon the
       revocation of any such appointment, thereafter, until a new appointment
       is similarly made) the Secretary of the Corporation shall be the
       transfer agent of the Corporation without the necessity of any formal
       action of the Board, and the Secretary, or any person designated by
       him/her, shall perform all of the duties thereof.

 47.   Registered Stockholders.  Only registered stockholders shall be entitled
       to be treated by the Corporation as the holders and owner in fact of
       the shares standing in their respective names, and the Corporation shall
       not be bound to recognize any equitable or other claim to or interest in
       such shares on the part of any other person, whether or not it shall
       have express or other notice thereof, except as expressly provided by
       the laws of Kansas.

 48.   Lost Certificates.  The Board of Directors may authorize the Secretary
       to direct that a new certificate or certificates be issued in place of
       any certificate or certificates theretofore issued by the Corporation,
       alleged to have been lost, stolen or destroyed, upon the making of an
       affidavit of the fact by the person claiming the certificate or
       certificates to be lost, stolen or destroyed.  When authorizing such
       issue of a replacement certificate or certificates, the Secretary may,
       as a condition precedent to the issuance thereof, require the owner of
       such lost, stolen or destroyed certificate or certificates, or his/her
       legal representative, to give the Corporation and its transfer agents
       and registrars, if any, a bond in such sum as it may direct to indemnify
       it against any claim that may be made against it with respect to the
       certificate or certificates alleged to have been lost, stolen or
       destroyed, or with respect to the issuance of such new certificate or
       certificates.

       be more than sixty (60) days not less than ten (10) days before the date

             distributed.

       C.    If any of the net earnings of this Corporation is profit from sale
             of its securities or from any source that would be considered as
             capital gains, this information shall be clearly revealed to the
             stockholders and the basis of calculation of such gains set forth.

       D.    The officers and Directors shall distribute not less than that
             amount of net earnings of this Corporation to its shareholders as
             may be required or advisable under applicable law and special
             distribution of net earnings may be made at the discretion of the
             Directors at any time to meet this requirement or for any other
             reason.

 62.   Underwriting or Principal Broker Agreement.

       A.    The officers and Directors of this Corporation shall not enter
             into an agreement or contract with any person or corporation to
             act as underwriter or principal broker for the sale and/or
             distribution of its shares, unless said person or corporation is
             fully qualified as a broker and has net all the requirements of
             the Kansas Corporation Commission and United States Securities and
             Exchange Commission and is currently in good standing with said
             Commissions.

       B.    No commission, sales load or discount from the offering price of
             said shares shall be greater than that which is permitted under
             the Investment Company Act of 1940 and the rules, regulations and
             orders promulgated thereunder.

       C.    Any such contract so made shall not endure for a period of more
             than on year, unless such extension has been duly ratified and
             approved by a majority vote of the Directors of the Corporation,
             and such contract shall contain a provision that it may be
             terminated for cause upon sixty days written notice by either
             party.

                                 MISCELLANEOUS

 63.   Waiver of Notice.  Whenever any notice is required to be given under the
       provisions of the statutes of Kansas, or of the Articles of
       Incorporation or of these Bylaws, a waiver thereof in writing, signed by
       the person or persons entitled to said notice, whether before or after
       the time stated therein, shall be deemed equivalent to notice.

       of such meeting, except when the person attends a meeting for the
       express purpose of objecting, at the beginning of the meeting, to the
       transaction of any business because the meeting is not lawfully called
       or convened.  Neither the business to be transacted at, nor the purpose
       of, any regular or special meeting of the stockholders, Directors or
       members of a committee of directors need be specified in any written
       waiver of notice unless so required by the Articles of Incorporation of
       these Bylaws.

       officers, or agent or agents, to enter into any contract or execute and

       on behalf of the Corporation, and such authority may be general or
       confined to specific instances.

 65.   Amendments.  These Bylaws may be altered, amended or repealed, or new
       Bylaws may be adopted, in any of the following ways:  (i) by the holders
       of a majority of the outstanding shares of stock of the Corporation
       entitled to vote, or (ii) by a majority of the full Board of Directors
       and any change so made by the stockholders may thereafter be further
       changed by a majority of the directors; provided, however, that the
       power of the Board of Directors to alter, amend or repeal the Bylaws, or
       to adopt new Bylaws, may be denied as to any Bylaws or portion thereof
       as the stockholders shall so expressly provide.

                          INVESTMENT ADVISORY CONTRACT

THIS AGREEMENT, made this 27th day of March, 1987, between SECURITY INCOME
FUND, a Kansas corporation (hereinafter referred to as the "Fund"), and
SECURITY MANAGEMENT COMPANY, a Kansas corporation (hereinafter referred to as
the "Management Company"),

                                  WITNESSETH:

WHEREAS, the Fund is engaged in business as an open-end management investment
company registered under the Federal Investment Company Act of 1940; and

WHEREAS, the Fund is authorized to issue shares of capital stock in separate
Series, with each such Series representing interests in a separate portfolio of
securities and other assets; and

WHEREAS, the Fund currently offers shares in three separate series designated
the Corporate Bond Series, the U.S. Government Series, and the High Yield
Series (the "Series"), such series together with all other series subsequently
established by the Fund with respect to which the Fund desires to retain the
Management Company to render investment advisory services hereunder and with
respect to which the Management Company is willing so to do, being herein
collectively referred to as the "Series", and

WHEREAS, the Management Company is willing to provide investment research and
advice to the Fund on the terms and conditions hereinafter set forth;

NOW, THEREFORE, in consideration of the premises and mutual agreements made
herein, the parties hereto agree as follows:

1.    EMPLOYMENT OF MANAGEMENT COMPANY.  The Fund hereby employs the Management
      Company to act as investment adviser to each Series of the Fund with
      respect to the investment of its assets, and to supervise and arrange the
      purchase of securities for and the sale of securities held in the
      portfolios of the Series of the Fund, subject always to the supervision
      of the Board of Directors of the Fund, during the period and upon and
      subject to the terms and conditions herein set forth. The Management
      Company hereby accepts such employment and agrees to perform the services
      required by this Agreement for the compensation herein provided.

      In the event the Fund establishes additional series with respect to which
      it desires to retain the Management Company to render investment advisory
      services hereunder, it shall notify the Management Company in writing.
      If the Management Company is willing to render such services it shall
      notify the Fund in writing, whereupon such series shall become a Series
      subject to the terms and conditions hereunder, and to such amended or
      additional provisions as shall be specifically agreed to by the Fund and
      the Management Company in accordance with applicable law.
<PAGE>   2


2.    INVESTMENT ADVISORY DUTIES.  The Management Company shall regularly
      provide each Series of the Fund with investment research, advice and
      supervision, continuously furnish an investment program and recommend
      that securities shall be purchased and sold and what portion of the
      assets of each series shall be held uninvested and shall arrange for the
      purchase of securities and other investments for and the sale of
      securities and other investments held in the portfolio of each Series.
      All investment advice furnished by the Management Company to each Series
      under this Section 2 shall at all times conform to any requirements
      imposed by the provisions of the Fund's Articles of Incorporation and
      Bylaws, the Investment Company Act of 1940 and the rules and regulations
      promulgated thereunder, any other applicable provisions of law, and the
      terms of the registration statements of the Fund under the Securities Act
      of 1933 and the Investment Company Act of 1940, all as from time to time
      amended.  The Management Company shall advise and assist the officers or
      other agents of the Fund in taking such steps as are necessary or
      appropriate to carry out the decisions of the Fund's Board of Directors
      (and any duly appointed committee thereof) with regard to the foregoing
      matters and the general conduct of the Fund's business.

3.    PORTFOLIO TRANSACTIONS AND BROKERAGE.

      (a)    Transactions in portfolio securities shall be effected by the
             Management Company, through brokers or otherwise, in the manner
             permitted in this Section 3 and in such manner as the Management
             Company shall deem to be in the best interests of the Fund after
             consideration is given to all relevant factors.

      (b)    In reaching a judgment relative to the qualification of a broker
             to obtain the best execution of a particular transaction, the
             Management Company may take into account all relevant factors and
             circumstances, including the size of any contemporaneous market in
             such securities; the importance to the Fund of speed and
             efficiency of execution; whether the particular transaction is
             part of a larger intended change in portfolio position in the same
             securities; the execution capabilities required by the
             circumstances of the particular transaction; the capital required
             by the transaction; the overall capital strength of the broker;
             the broker's apparent knowledge of or familiarity with sources
             from or to whom such securities may be purchased or sold; as well
             as the efficiency, reliability and confidentiality with which the
             broker has handled the execution of prior similar transactions.

      (c)    Subject to any statements concerning the allocation of brokerage
             contained in the Fund's prospectus or statement of additional
             information, the Management Company is authorized to direct the
             execution of portfolio transactions for the Fund to brokers who
             furnish investment information or research service to the
             Management Company.  Such allocation shall be in such amounts and
             proportions as the Management Company may determine.  If the
             transaction is directed to a broker providing brokerage and
             research services to the Management Company, the commission paid
             for such transaction may be in excess of the commission another
             broker would have charged for effecting that transaction, if the
             Management Company shall have determined in good faith that the
             commission is reasonable in relation to the value of
<PAGE>   3

             the brokerage and research services provided, viewed in terms of
             either that particular transaction or the overall responsibilities
             of the Management Company with respect to all accounts as to which
             it now or hereafter exercises investment discretion.  For purposes
             of the immediately preceding sentence, "providing brokerage and
             research services" shall have the meaning generally given such
             terms or similar terms under Section 28(e)(3) of the Securities
             Exchange Act of 1934, as amended.

      (d)    In the selection of a broker for the execution of any transaction
             not subject to fixed commission rates, the Management Company
             shall have no duty or obligation to seek advance competitive
             bidding for the most favorable negotiated commission rate to be
             applicable to such transaction, or to select any broker solely on
             the basis of its purported or "posted" commission rates.

      (e)    In connection with transactions on markets other than national or
             regional securities exchanges, the Fund will deal directly with
             the selling principal or market maker without incurring charges
             for the services of a broker on its behalf unless, in the best
             judgment of the Management Company, better price or execution can
             be obtained in utilizing the services of a broker.

4.    ALLOCATION OF EXPENSES AND CHARGES.  The Management Company shall provide
      investment advisory, statistical and research facilities and all clerical
      services relating to research, statistical and investment work, and shall
      provide for the compilation and maintenance of such records relating to
      these functions as shall be required under applicable law and the rules
      and regulations of the Securities and Exchange Commission.  The
      Management Company will also provide the Fund with a president, a chief
      financial officer, and a secretary, subject to the approval of the Board
      of Directors, and will pay the salaries and expenses of such officers of
      the Fund who are also directors, officer or employees of the Management
      Company.

      Other than as specifically indicated in the preceding sentences, the
      Management Company shall not be required to pay any expenses of the Fund,
      and in particular, but without limiting the generality of the foregoing,
      the Management Company shall not be required to pay office rental or
      general administrative expenses; Board of Directors' fees; legal,
      auditing and accounting expenses; insurance premiums; broker's
      commissions; taxes and governmental fees and any membership dues; fees of
      custodian, transfer agent, registrar and dividend disbursing agent (if
      any); expenses of obtaining quotations on the Fund's portfolio securities
      and pricing of the Fund's shares; cost of stock certificates and any
      other expenses (including clerical expenses) of issue, sale, repurchase
      or redemption of shares of the Fund's capital stock; costs and expenses
      in connection with the registration of the Fund's capital stock under the
      Securities Act of 1933 and qualification of the Fund's capital stock
      under the Blue Sky laws of the states where such stock is offered; costs
      and expenses in connection with the registration of the Fund under the
      Investment Company Act of 1940 and all periodic and other reports
      required thereunder; expenses of preparing, printing and distributing
      reports, proxy statements, prospectuses, statements or additional
      information, notices and distributions to stockholders; costs of
      stationery; costs of stockholder and other meetings;
<PAGE>   4

      expenses of maintaining the Fund's corporate existence; and such
      nonrecurring expenses as may arise including litigation affecting the
      Fund and the legal obligations the Fund may have to indemnify its
      officers and directors.

5.    COMPENSATION OF MANAGEMENT COMPANY.

      (a)    As compensation for the services rendered by the Management
             Company as provided herein, for each of the Fund's fiscal years
             this Agreement is in effect, the Fund shall pay the Management
             Company an annual fee equal to .5 percent of the average daily
             closing value of the net assets of each Series computed on a daily
             basis.  Such fee shall be adjusted and payable monthly.  If this
             Agreement shall be effective for only a portion of a year in which
             a fee is owed for any Series, then the Management Company's
             compensation for said year shall be prorated for such portion.
             For purposes of this Section 5, the value of the net assets of the
             Series shall be computed in the same manner as the value of such
             net assets is computed in connection with the determination of the
             net asset value of the shares of the Fund as described in the
             Fund's Prospectus and Statement of Additional Information. The net
             asset value of each Series shall be included in and comprise a
             part of the net assets of the Fund for purposes of determining
             said fee under this Section.

      (b)    For each of the Fund's full fiscal years this Agreement remains
             in force, the Management Company agrees that if the total annual
             expenses of each Series of the Fund, exclusive of interest and
             taxes and extraordinary expenses (such as litigation), but
             inclusive of the Management Company's compensation, exceed any
             expense limitation imposed by state securities law or regulation
             in any state in which shares of the Fund are then qualified for
             sale, as such regulations may be amended from time to time, the
             Management Company will contribute to such Series such funds or
             to waive such portion of its fee, adjusted monthly as may be
             requisite to insure that such annual expenses will not exceed
             any such limitation.  If this Contract shall be effective for
             only a portion of one of the Series' 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 a Series shall not be
             deemed to be expenses with the meaning of this paragraph (b).
             
6.    MANAGEMENT COMPANY NOT TO RECEIVE COMMISSIONS.  In connection with the
      purchase or sale of portfolio securities for the account of the Fund,
      neither the Management Company nor any officer or director of the
      Management Company shall act as principal or receive any compensation
      from the Fund other than its compensation as provided for in Section 5
      above.  If the Management Company, or any "affiliated person" (as defined
      in the Investment Company Act of 1940) receives any cash, credits,
      commissions or tender fees from any person in connection with
      transactions in the Fund's portfolio securities (including but not
      limited to the tender or delivery of any securities held in the Fund's
      portfolio), the Management Company shall immediately pay such amount to
      the Fund in cash or as a credit against any then earned but unpaid
      management fees due by the Fund to the Management Company.
<PAGE>   5

7.    LIMITATION OF LIABILITY OF MANAGEMENT COMPANY.  So long as the Management
      Company shall give the Fund the benefit of its best judgment and effort
      in rendering services hereunder, the Management Company shall not be
      liable for any errors of judgment or mistake of law, or for any loss
      sustained by reason of the adoption of any investment policy or the
      purchase, sale or retention of any security on its recommendation,
      whether or not such recommendation shall have been based upon its own
      investigation and research or upon investigation and research made by any
      other individual, firm or corporation, if such recommendation shall have
      been made and such other individual, firm or corporation shall have been
      selected with due care and in good faith.  Nothing herein contained
      shall, however, be construed to protect the Management Company against
      any liability to the Fund or its security holders by reason of willful
      misfeasance, bad faith or gross negligence in the performance of its
      duties or by reason of its reckless disregard of its obligations and
      duties under this Agreement.  As used in this Section 7, "Management
      Company" shall include directors, officers and employees of the
      Management Company, as well as that corporation itself.

8.    OTHER ACTIVITIES NOT RESTRICTED.  Nothing in this Agreement shall prevent
      the Management Company or any officer thereof from acting as investment
      adviser for any other person, firm, or corporation, nor shall it in any
      way limit or restrict the Management Company or any of its directors,
      officers, stockholders or employees from buying, selling, or trading any
      securities for its own accounts or for the accounts of others for whom it
      may be acting; provided, however, that the Management Company expressly
      represents that it will undertake no activities which, in its judgment,
      will conflict with the performance of its obligations to the Fund under
      this Agreement.  The Fund acknowledges that the Management Company acts
      as investment adviser to other investment companies, and it expressly
      consents to the Management Company acting as such; provided, however,
      that if in the opinion of the Management Company, particular securities
      are consistent with the investment objectives of, and are desirable
      purchases or sales for the portfolios of one or more Series and one or
      more of such other investment companies or series of such companies at
      approximately the same time, such purchases or sales will be made on a
      proportionate basis if feasible, and if not feasible, then on a rotating
      or other equitable basis.

9.    DURATION AND TERMINATION OF AGREEMENT.  This Agreement shall become
      effective on March 27, 1987, provided that on that date it is approved by
      the holders of a majority of the outstanding voting securities of each
      Series of the Fund.  This Agreement shall continue in force until
      April 1, 1988, and for successive 12-month periods thereafter, unless
      terminated, provided each such continuance is specifically approved at
      least annually by (a) the vote of a majority of the entire Board of
      Directors of the Fund, and the vote of a majority of the directors of the
      Fund who are not parties to this Agreement or interested persons (as such
      terms are defined in the Investment Company Act of 1940) of any such
      party cast in person at a meeting of such directors called for the
      purpose of voting upon such approval, or (b) by the vote of the holders
      of a majority of the outstanding voting securities of each series of the
      Fund (as defined in the Investment Company Act of 1940).  In the event a
      majority of the outstanding shares of one series vote for continuance of
      the Advisory Contract, it will be
<PAGE>   6

      continued for that series even though the Advisory Contract is not
      approved by either a majority of the outstanding shares of any other
      series or by a majority of outstanding shares of the Fund.  Upon this
      Agreement becoming effective, any previous agreement between the Fund and
      the Management Company providing for investment advisory and management
      services shall concurrently terminate, except that such termination shall
      not affect fees accrued and guarantees of expenses with respect to any
      period prior to termination.

      This Agreement may be terminated at any time as to any series of the
      Fund, without payment of any penalty, by vote of the Board of Directors
      of the Fund or by vote of the holders of a majority of the outstanding
      voting securities of that series of the Fund, or by the Management
      Company, upon 60 days' written notice to the other party.

      This Agreement shall automatically terminate in the event of its
      "assignment" (as defined in the Investment Company Act of 1940).

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly
executed by their respective corporate officers thereto duly authorized on the
day, month and year first above written.

                   AMENDMENT TO INVESTMENT ADVISORY CONTRACT

WHEREAS, Security Income Fund (the "Fund") and Security Management Company (the
"Management Company") are parties to an Investment Advisory Contract dated
March 27, 1987 (the "Agreement"), under which the Management Company agrees to
provide investment research and advice to the Fund in return for the
compensation specified in the Agreement;

WHEREAS, Security Income Fund currently offers its shares in two series, the
Corporate Bond Series and the U.S. Government Series (hereinafter collectively
referred to as the "Series");

WHEREAS, effective October 19, 1993, the Fund will offer its shares in two
Classes, Class A shares, which are currently being offered, and a new class,
Class B shares;

WHEREAS, the Fund has adopted a Distribution Plan with respect to its Class B
shares and, as a result, such shares are subject to distribution fees to which
Class A shares are not subject;

WHEREAS, the distribution fees associated with Class B shares require the
amendment of the Agreement relative to that class of shares;

WHEREAS, on October 1, 1993, the initial Class B shareholder of each Series of
the Fund approved such amendment to this Agreement;

WHEREAS, the changes to the Agreement which are contemplated by this Amendment
do not affect the interests of Class A shareholders of the Fund;

NOW, THEREFORE, the Fund and the Management Company hereby amend the Investment
Advisory Contract, dated March 27, 1987, effective October 1, 1993, as follows:

A.    The Management Company agrees to provide investment research and advice,
      to the Fund pursuant to the terms and conditions set forth in the
      Agreement, as amended in section B below.

B.    Section 5(b) of the Agreement shall be amended by deleting it in its
      entirety and replacing it with the following:

      (b)    For each of the Fund's full fiscal years this Agreement remains in
             force, the Management Company agrees that if the total annual
             expenses of each Series of the Fund, exclusive of interest and
             taxes, extraordinary expenses (such as litigation), and
             distribution fees paid under the Fund's Class B Distribution Plan,
             but inclusive of the Management Company's compensation, exceed any
             expense limitation imposed by state securities law or regulation
             in any state in which shares of the Fund are then qualified for
             sale, as such regulations may be amended from time to time, the
             Management Company will contribute to such Series such funds or
             waive such portion of its fee, adjusted monthly as may be
             requisite to insure that such annual expenses will not exceed any
             such limitation.  If this Contract shall be effective for only a
             portion of
<PAGE>   8

             one of the Series' 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 a Series shall not be deemed to be expenses with
             the meaning of this paragraph (b).

IN WITNESS WHEREOF, the parties hereto have made this Amendment to the
Investment Advisory Contract this 1st day of October 1993.

                             SUB-ADVISORY AGREEMENT

THIS AGREEMENT is made this ______ day of ___________________ 1995, by and
between SECURITY MANAGEMENT COMPANY, a Kansas Corporation (The "Adviser"), and
LEXINGTON MANAGEMENT CORPORATION, a Delaware corporation (the "Sub-Adviser"),

WITNESSETH:

WHEREAS, the Adviser is a registered investment adviser under the Investment
Advisers Act of 1940, as amended, and engages in the business of acting as an
investment adviser;

WHEREAS, the Adviser is the investment adviser for the Security Income Fund
(the "Fund"), and provides investment advisory services to the Fund on the
terms and conditions set forth in an investment advisory contract;

WHEREAS, the Fund is registered as a diversified, open-end investment company
under the Investment Company Act of 1940, as amended, (the "1940 Act"), and the
rules and regulations promulgated thereunder;

WHEREAS, the Fund is authorized to issue shares in separate series, with each
such series representing interests in a separate portfolio of securities and
other assets; and

WHEREAS, the Adviser desires to retain the Sub-Adviser as the Adviser's agent
to furnish certain advisory services to the Global Aggressive Bond Series of
the Fund (the "Series"), on the terms and conditions hereinafter set forth.
<PAGE>   2

NOW THEREFORE, in consideration of the mutual covenants herein contained and
other good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereto agree as follows:

1.   APPOINTMENT.  The Adviser hereby appoints Sub-Adviser to provide certain
     sub-investment advisory services to the Series for the period and on the
     terms set forth in this Agreement.  Sub-Adviser accepts such appointment
     and agrees to furnish the services herein set forth for the compensation
     herein provided.
2.   INVESTMENT ADVICE.  The Sub-Adviser shall furnish the Series with
     investment research and advice consistent with the investment policies set
     forth in the Prospectus and Statement of Additional Information of the
     Fund, subject at all times to the policies and control of the Fund's Board
     of Directors and the supervision of the Adviser.  In addition, the
     Sub-Adviser may avail itself of any investment research or advice provided
     by the Adviser.  The Sub-Adviser shall give the Series the benefit of its
     best judgment, efforts and facilities in rendering its services as
     Sub-Adviser.
3.   INVESTMENT ANALYSIS AND IMPLEMENTATION.  In carrying out its obligation
     under paragraph 2 hereof, the Sub-Adviser shall:
     (a)         determine which issuers and securities shall be represented in
                 the Series' portfolio and regularly report thereon to the
                 Fund's Board of Directors and the Adviser;
     (b)         formulate and implement continuing programs for the purchase
                 and sale of the securities of such issuers and regularly
                 report thereon to the Fund's Board of Directors and the
                 Adviser;
     (c)         continuously review the Series' security holdings and the
                 investment program and the investment policies of the Series; 
                 and
     (d)         take, on behalf of the Series, all actions which appear
                 necessary to carry into effect such purchase and sale
                 programs, including the placement of orders for the purchase
                 and sale of securities for the Series.





                                       2
<PAGE>   3

4.   BROKER-DEALER RELATIONSHIPS.  The Sub-Adviser is responsible for decisions
     to buy and sell securities for the Series, broker/dealer selection, and
     negotiation of brokerage commission rates.  The Sub-Adviser's primary
     consideration in effecting a security transaction will be execution at the
     most favorable price.  In selecting a broker/dealer to execute each
     particular transaction, the Sub-Adviser will take the following into
     consideration:  the best net price available; the reliability, integrity
     and financial condition of the broker/dealer; the size of and difficulty
     in executing the order; and the value of the expected contribution of the
     broker/dealer to the investment performance of the Series on a continuing
     basis.  Accordingly, the price to the Series in any transaction may be
     less favorable than that available from another broker/dealer if the
     difference is reasonably justified by other aspects of the portfolio
     execution services offered.  Subject to such policies as the Board of
     Directors may determine, the Sub-Adviser shall not be deemed to have acted
     unlawfully or to have breached any duty created by this Agreement or
     otherwise solely by reason of its having caused the Series to pay a broker
     for effecting a portfolio investment transaction in excess of the amount
     of commission another broker or dealer would have charged for effecting
     that transaction if the Sub-Adviser determines in good faith that such
     amount of commission was reasonable in relation to the value of the
     brokerage and research services provided by such broker or dealer, viewed
     in terms of either that particular transaction or the Sub-Adviser's
     overall responsibilities with respect to the Series and to its other
     clients as to which it exercises investment discretion.  The Sub-Adviser
     is further authorized to place and/or to effect orders with such brokers
     and dealers who may provide research or statistical material or other
     services to the Series or to the Sub-Adviser.  Such allocation shall be in
     such amounts and proportions as the Sub-Adviser shall determine and the
     Sub-Adviser will report on said allocations regularly to the Board of
     Directors of the Fund and the Adviser indicating the brokers to whom such
     allocations have been made and the basis therefor.

<PAGE>   4

5.   CONTROL BY BOARD OF DIRECTORS.  Any investment program undertaken by the
     Sub-Adviser pursuant to this Agreement, as well as any other activities
     undertaken by the Sub-Adviser on behalf of the Series pursuant thereto,
     shall at all times be subject to any directives of the Board of Directors
     of the Fund.
6.   COMPLIANCE WITH APPLICABLE REQUIREMENTS.  In carrying out its obligations
     under this Agreement, the Sub-Adviser shall ensure that the Series
     complies with:
     (a)         all applicable provisions of the 1940 Act;
     (b)         the provisions of the Registration Statement of the Fund, as
                 amended, under the Securities Act of 1933 and the 1940 Act;
     (c)         all applicable statutes and regulations necessary to qualify
                 the Series as a Regulated Investment Company under Subchapter
                 M of the Internal Revenue Code (or any successor or similar
                 provision), and shall notify the Adviser immediately upon
                 having a reasonable basis for believing that the Series has
                 ceased to so qualify or that it might not so qualify in the
                 future;
     (d)         the provisions of the Fund's Articles of Incorporation, as
                 amended;
     (e)         the provisions of the Bylaws of the Fund, as amended; and
     (f)         any other applicable provisions of state and federal law.
7.   RECORDS.  The Sub-Adviser hereby agrees to maintain all records relating
     to its activities and obligations under this Agreement which are required
     to be maintained by Rule 31a-1 under the 1940 Act and agrees to preserve
     such records for the periods prescribed by Rule 31a-2 under the Act.  The
     Sub-Adviser further agrees that all such records are the property of the
     Fund and agrees to surrender promptly to the Fund any such records upon
     the Fund's request.
8.   EXPENSES.  The expenses connected with the Fund shall be borne by the
     Sub-Adviser as follows:
     (a)         The Sub-Adviser shall maintain, at its expense and without

                 of portfolio securities for the Series.
     (b)         The Sub-Adviser shall pay any expenses associated with
                 carrying out its obligation under subparagraph (b) of
                 paragraph 2 hereof to prepare reports for the Fund's Board of
                 Directors concerning issuers and securities represented in the
                 Series' portfolio and the expenses of any travel by employees
                 of the Sub-Adviser in connection with such reports to the
                 Fund's Board of Directors.
     (c)         The Sub-Adviser shall pay any expenses that it may incur in
                 communicating with the Adviser in connection with its
                 obligations under this Agreement, including the expenses of
                 telephone calls, special mail services and telecopier charges.
 9.    DELEGATION OF RESPONSIBILITIES.  Upon request of the Adviser and with

       Agreement.  Such services will be performed on behalf of the Fund, and
       the Sub-Adviser's cost in rendering such services may be billed monthly
       to the Adviser, subject to examination by the Adviser's independent
       accountants.  Payment or assumption by the Sub-Adviser of any Fund

       assume any similar Fund expense on any subsequent occasions.
10.    DELEGATION OF DUTIES.  The Sub-Adviser may, at its discretion, delegate,
       assign or subcontract any of the duties, responsibilities and services
       governed by this agreement to a third party, whether or not by formal
       written agreement, provided that such arrangement with a third party has
       been approved by the Board of Directors of the Fund.  The Sub-Adviser
       shall, however, retain ultimate responsibility to the Fund and shall
       implement such reasonable procedures as may be necessary for assuring
       that any duties, responsibilities or services so assigned, subcontracted
       or delegated are performed in conformity with the terms and conditions
       of this agreement.

11.    COMPENSATION.  For the services to be rendered and the facilities
       furnished hereunder, the Adviser shall pay the Sub-Adviser an annual fee
       equal to .35 percent of the average daily closing value of the net
       assets of the Series, computed on a daily basis.  Such fee shall be
       computed and payable monthly.  If this Agreement shall be effective for
       only a portion of a year, then the Sub-Adviser's compensation for said
       year shall be prorated for such portion.  For purposes of this
       paragraph 11, the value of the net assets of the Series 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 Series' shares as described in the Fund's
       prospectus and statement of additional information.  Payment of the
       Sub-Adviser's compensation for the preceding month shall be made as
       promptly as possible after the end of each month.
12.    NON-EXCLUSIVITY.  The services of the Sub-Adviser to the Adviser are not
       to be deemed to be exclusive, and the Sub-Adviser shall be free to
       render investment advisory or other services to others (including other
       investment companies) and to engage in other activities, so long as its
       services under this Agreement are not impaired thereby.
13.    TERM.  This Agreement shall become effective at the close of business on
       the date first shown above.  It shall remain in force and effect,
       subject to paragraph 14 hereof for one year from the date hereof.
14.    RENEWAL.  Following the expiration of its initial year term, this
       Agreement shall continue in force and effect from year to year, provided
       that such continuance is specifically approved at least annually:
       (a)       (i) by the Fund's Board of Directors or (ii) by the vote of a
                 majority of the Series' outstanding voting securities (as
                 defined in Section 2(a)(42) of the 1940 Act), and
       (b)       by the affirmative vote of a majority of the directors who are
                 not parties to this Agreement or interested persons of a party
                 to this Agreement (other than as a director of the Fund), by
                 votes cast in person at a meeting specifically called for such
                 purpose.

       payment of any penalty, by vote of the Fund's Board of Directors or by
       vote of a majority of the Series' outstanding voting securities (as
       defined in Section 2(a)(42) of the 1940 Act), or by the Adviser or by
       the Sub-Adviser on sixty (60) days' written notice to the other party.
       This Agreement shall automatically terminate in the event of its
       "assignment" as that term is defined in Section 2(a)(4) of the 1940 Act.
       This Agreement shall automatically terminate in the event that the
       investment advisory contract between the Adviser and the Fund is
       terminated, assigned or not renewed.
16.    LIABILITY OF THE SUB-ADVISER.  In the absence of willful misfeasance,
       bad faith or gross negligence on the part of the Sub-Adviser or its
       officers, directors or employees, or reckless disregard by the
       Sub-Adviser of its duties under this Agreement, the Sub-Adviser shall
       not be liable to the Adviser, the Fund or to any shareholder of the Fund
       for any act or omission in the course of, or connected with, rendering
       services hereunder or for any losses that may be sustained in the
       purchase, holding or sale of any security, provided the Sub-Adviser has
       acted in good faith.
17.    INDEMNIFICATION.  The Adviser and the Sub-Adviser each agree to
       indemnify the other against any claim against, loss, or liability to,
       such other party (including reasonable attorney's fees) arising out of
       any action on the part of the indemnifying party which constitutes
       willful misfeasance, bad faith or gross negligence.
18.    NOTICES.  Any notices under this Agreement shall be in writing,
       addressed and delivered or mailed postage-paid to the other party at

                             DISTRIBUTION AGREEMENT


THIS AGREEMENT, made this 14th day of September, 1970, between SECURITY BOND
FUND, INC., a Kansas corporation (hereinafter referred to as the "Company"),
and SECURITY DISTRIBUTORS, INC., a Kansas corporation (hereinafter referred to
as the "Distributor").

                                  WITNESSETH:

WHEREAS, the Company is engaged in business as an open-end, management
investment company registered under the federal Investment Company Act of 1940;
and

WHEREAS, the Distributor is willing to act as principal underwriter for the
Company to offer for sale, sell and deliver after sale shares of the Company's
$1 par value common stock (hereinafter referred to as the "Shares") on the
terms and conditions hereinafter set forth;

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein
set forth, the parties hereto agree as follows:

1.    Employment of Distributor.  The Company hereby employs the Distributor to
      act as principal underwriter for the Company and hereby agrees that
      during the term of this Agreement, and any renewal or extension thereof,
      or until any prior termination thereof, the Distributor shall have the
      exclusive right to offer for sale and to distribute any and all Shares
      issued or to be issued by the Company.  The Distributor hereby accepts
      such employment and agrees to act as the distributor of the Shares issued
      or to be issues by the Company during the period this Agreement is in
      effect and agrees during such period to offer for sale such Shares as
      long as such Shares remain available for sale, unless the Distributor is
      unable legally to make such offer for sale as the result of any law or
      governmental regulation.

2.    Offering Price and Commissions.  Prior to the issuance of any Shares by
      the Company pursuant to any subscription tendered by or through the
      Distributor and confirmed for sale to or through the Distributor, the
      Distributor shall pay or cause to be paid to the Custodian of the Company
      in cash, an amount equal to the net asset value of such Shares at the
      time of acceptance of each such subscription and confirmation by the
      Company of the sale of such Shares.  The Distributor shall be entitled to
      charge a commission on each such sale of Shares in the amount set forth
      in the Company's Prospectus, such commission to be an amount equal to the
      difference between the net asset value and the offering price of the
      Shares, as such offering price may from time to time be determined by the
      board of directors of the Company.  All Shares shall be sold to the
      public only at their public offering price at the time of such sale, and
      the Company shall receive not less than the full net asset value thereof.

3.    Allocation of Expenses and Charges.  During the period this Agreement is
      in effect, the Company shall pay all costs and expenses in connection
      with the registration of Shares under the Securities Act of 1933,
      including all expenses in connection with the preparation and printing of
      any registration statements and prospectuses necessary for registration
      thereunder but excluding any additional costs and expenses incurred in
      furnishing the Distributor with prospectuses.
<PAGE>   2


      During the period this Agreement is in effect the Distributor will pay or
      reimburse the Company for:

      (a)    All costs, expenses and fees incurred in connection with the
             qualification of the Shares under the applicable Blue Sky laws of
             the states in which the Shares are offered;

      (b)    All costs and expenses of printing and mailing prospectuses (other
             than to existing shareholders) and confirmations, and all costs
             and expenses of preparing, printing and mailing advertising
             material sales literature, circulars, applications, and other
             materials used or to be used in connection with the offering for
             sale and the sale of Shares; and

      (c)    All clerical and administrative costs in processing the
             applications for and in connection with the sale of Shares.

             The Distributor agrees to submit to the Company for its prior
             approval all advertising material, sales literature, circulars     
             and any other material which the Distributor proposes to use in
             connection with the offering for sale of Shares.

4.    Distributor May Act as Broker and Receive Commissions.  Notwithstanding
      any other provisions of this Agreement, it is understood and agreed that
      the Distributor may act as a broker, on behalf of the Company, in the
      purchase and sale of securities not effected on a securities exchange,
      provided that any such transactions and any commission paid in connection
      therewith shall comply in every respect with the requirements of the
      Federal Investment Company Act of 1940 and in particular with Section
      17(c) of said statute and the Rules and Regulations of the Securities and
      Exchange Commission promulgated thereunder.

5.    Agreement Subject to Applicable Law and Regulations.  The parties hereto
      agree that all provisions of this Agreement will be performed in strict
      accordance with the requirements of the Investment Company Act of 1940,
      the Securities Act of 1933, the Securities Exchange Act of 1934, and the

      laws and the rules and regulations thereunder, and in strict accordance
      with the provisions of the Articles of Incorporation and Bylaws of the
      Company.

             computed at an annual rate of .25 of 1% of the Fund's average
             daily net assets, to finance activities undertaken by the
             Distributor for the purpose of distributing the Fund's shares to

                  (i)     Preparation, printing and distribution of the
                          Prospectus and Statement of Additional Information
                          and any supplement thereto used in connection with

                          sales literature used in connection with the offering
                          of shares to the public;

                 (iv)     Expenses incurred in advertising, promoting and

                  (v)     Any fees paid by the Distributor to securities
                          dealers as distribution or service fees who have
                          executed a Dealer's Distribution Agreement with the
                          Distributor.

             (b)   All payments to the Distributor pursuant to this paragraph
                   are subject to the following conditions being met by the
                   Distributor:

                  (i)     For the fiscal year of the Fund during which this
                          Plan becomes effective and for each subsequent fiscal
                          year of the Fund during which this Plan remains in
                          effect, the Distributor shall submit to the Fund a
                          budget setting forth in reasonable detail the
                          distribution-related activities to which the
                          Distributor proposes to apply payments made by the
                          Fund hereunder;

                 (ii)     Before any payment is made to the Distributor in
                          respect of any fiscal year, the budget relating
                          thereto shall be approved by vote of the Fund's
                          Directors, including the affirmative vote of a
                          majority of the Independent Directors.

                (iii)     The Distributor shall furnish the Fund with quarterly
                          reports of its expenditures pursuant to each budget
                          so approved, together with receipts or other
                          appropriate written evidence of the amounts expended,
                          and such other information relating to such budget or
                          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;

             (c)   The Dealer's Distribution Agreement (the "Agreement")
                   contemplated by paragraph 2(v) above shall permit payments
                   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 a majority of the directors who are not
                   interested persons of the Fund as required by the Rule.  The
                   Distributor may pay to the other party to any Agreement a
                   quarterly fee for distribution and marketing services
                   provided by such other party.  Such quarterly fee shall be
                   payable in arrears in an amount equal to such percentage
                   (not in excess of .000685% per day) 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 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 quarterly fee.

             (d)   The provisions of the Distribution Plan approved by the
                   Shareholders of the Fund on July 12, 1985, and by the Board
                   of Directors of the Fund on May 3,
<PAGE>   9

                   1985, are fully incorporated herein by reference.  In the
                   event the Distribution Plan is terminated by the Board of
                   Directors or Shareholders of the Fund as provided therein,
                   this paragraph shall no longer be effective.

IN WITNESS WHEREOF, the parties hereto have made this Amendment to the
Distribution Agreement this 15th day of August 1985.

                                    CLASS B
                             DISTRIBUTION AGREEMENT


THIS AGREEMENT, made this 1st day of October 1993, between Security Income
Fund, a Kansas corporation (hereinafter referred to as the "Company"), and
Security Distributors, Inc., a Kansas corporation (hereinafter referred to as
the "Distributor").

                                  WITNESSETH:

WHEREAS, the Company is engaged in business as an open-end, management
investment company registered under the federal Investment Company Act of 1940
(the "1940 Act"); and

WHEREAS, the Distributor is willing to act as principal underwriter for the
Company to offer for sale, sell and deliver after sale, the Class B Shares of
the Company's $1.00 par value common stock (hereinafter referred to as the
"Shares") on the terms and conditions hereinafter set forth;

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein
set forth, the parties hereto agree as follows:

 1.   Employment of Distributor.  The Company hereby employs the Distributor to
      act as principal underwriter for the Company with respect to its Class B
      Shares and hereby agrees that during the term of this Agreement, and any
      renewal or extension thereof, or until any prior termination thereof, the
      Distributor shall have the exclusive right to offer for sale and to
      distribute any and all of its Class B Shares issued or to be issued by
      the Company.  The Distributor hereby accepts such employment and agrees
      to act as the distributor of the Class B Shares issued or to be issued by
      the Company during the period this Agreement is in effect and agrees
      during such period to offer for sale such Shares as long as such Shares
      remain available for sale, unless the Distributor is unable legally to
      make such offer for sale as the result of any law or governmental
      regulation.

 2.   Offering Price and Commissions.  Prior to the issuance of any Shares by
      the Company pursuant to any subscription tendered by or through the
      Distributor and confirmed for sale to or through the Distributor, the
      Distributor shall pay or cause to be paid to the custodian of the Company
      in cash, an amount equal to the net asset value of such Shares at the
      time of acceptance of each such subscription and confirmation by the
      Company of the sale of such Shares.  All Shares shall be sold to the
      public only at their public offering price at the time of such sale, and
      the Company shall receive not less than the full net asset value thereof.

 3.   Allocation of Expenses and Charges.  During the period this Agreement is
      in effect, the Company shall pay all costs and expenses in connection
      with the registration of Shares under the Securities Act of 1933 (the
      "1933 Act"), including all expenses in connection with the preparation
      and printing of any registration statements and prospectuses necessary
      for registration thereunder but excluding any additional costs and
      expenses incurred in furnishing the Distributor with prospectuses.





                                     -1-
<PAGE>   2

The Company will also pay all costs, expenses and fees incurred in connection
with the qualification of the Shares under the applicable Blue Sky laws of the
states in which the Shares are offered.

During the period this Agreement is in effect, the Distributor will pay or
reimburse the Company for:

      (a)    All costs and expenses of printing and mailing prospectuses (other
             than to existing shareholders) and confirmations, and all costs
             and expenses of preparing, printing and mailing advertising
             material, sales literature, circulars, applications, and other
             materials used or to be used in connection with the offering for
             sale and the sale of Shares; and

      (b)    All clerical and administrative costs in processing the
             applications for and in connection with the sale of Shares.

The Distributor agrees to submit to the Company for its prior approval all
advertising material, sales literature, circulars and any other material which
the Distributor proposes to use in connection with the offering for sale of
Shares.

 4.   Redemption of Shares.  The Distributor, as agent of and for the account
      of the Fund, may redeem Shares of the Fund offered for resale to it at
      the net asset value of such Shares (determined as provided in the
      Articles of Incorporation or Bylaws) and not in excess of such maximum
      amounts as may be fixed from time to time by an officer of the Fund.
      Whenever the officers of the Fund deem it advisable for the protection of
      the shareholders of the Fund, they may suspend or cancel such authority.

 5.   Sales Charges.  A contingent deferred sales charge shall be retained by
      the Distributor from the net asset value of Shares of the Fund that it
      has redeemed, it being understood that such amounts will not be in excess
      of that set forth in the then-current registration statement of the Fund.
      Furthermore, the Distributor may retain any amounts authorized for
      payment to it under the Fund's Distribution Plan.

 6.   Distributor May Act as Broker and Receive Commissions.  Notwithstanding
      any other provisions of this Agreement, it is understood and agreed that
      the Distributor may act as a broker, on behalf of the Company, in the
      purchase and sale of securities not effected on a securities exchange,
      provided that any such transactions and any commission paid in connection
      therewith shall comply in every respect with the requirements of the 1940
      Act and in particular with Section 17(e) of that Act and the rules and
      regulations of the Securities and Exchange Commission promulgated
      thereunder.

 7.   Agreements Subject to Applicable Law and Regulations.  The parties hereto
      agree that all provisions of this Agreement will be performed in strict
      accordance with the requirements of:  the 1940 Act, the 1933 Act, the
      Securities Exchange Act of 1934, the rules and regulations of the
      Securities and Exchange Commission under said statutes, all applicable
      state Blue Sky laws and the rules and regulations thereunder, the rules
      of the National Association of Securities Dealers, Inc., and, in strict
      accordance with, the provisions of the Articles of Incorporation and
      Bylaws of the Company.

8.  Duration and Termination of Agreement.  This Agreement shall become 
    effective at the date and time that the Company's prospectus, reflecting
    the underwriting arrangements provided by this Agreement, shall become
    effective under the 1933 Act, and shall, unless terminated as provided
    herein, continue in force for two years from that date, and from year to
    year thereafter, provided that such continuance for each successive year is
    specifically approved in advance at least annually by either the Board of
    Directors or by the vote of a majority (as defined in the 1940 Act) of the
    outstanding voting securities of the Company and, in either event, by the
    vote of a majority of the directors of the Company who are not parties to
    this Agreement or interested persons of any such party, cast in person at a
    meeting called for the purpose of voting upon such approval.  As used in
    the preceding sentence, the words "interested persons" shall have the
    meaning set forth in Section 2(a)(19) of the 1940 Act.  Written notice of
    any such approval by the Board of Directors or by the holders of a majority
    of the outstanding voting securities of the Company and by the directors
    who are not such interested persons shall be given promptly to the
    Distributor.

This Agreement may be terminated at any time without the payment of any penalty
by the Company by giving the Distributor at least sixty (60) days' previous
written notice of such intention to terminate.  This Agreement may be
terminated by the Distributor at any time by giving the Company at least sixty
(60) days' previous written notice of such intention to terminate.

This Agreement shall terminate automatically in the event of its assignment.
As used in the preceding sentence, the word "assignment" shall have the meaning
set forth in Section 2(a)(4) of the 1940 Act.

 9.   Construction of Agreement.  No provision of this Agreement is intended to
      or shall be construed as protecting the Distributor against any liability
      to the Company or to the Company's security holders to which the
      Distributor would otherwise be subject by reason of willful misfeasance,
      bad faith or gross negligence in the performance of its duties under this
      Agreement.

Terms or words used in the Agreement, which also occur in the Articles of
Incorporation or Bylaws of the Company, shall have the same meaning herein as
given to such terms or words in the Articles of Incorporation or Bylaws of the
Company.

10.   Distributor an Independent Contractor.  The Distributor shall be deemed
      to be an independent contractor and, except as expressly provided or
      authorized by the Company, shall have no authority to act for or
      represent the Company.

11.   Notice.  Any notice required or permitted to be given hereunder to either
      of the parties hereto shall be deemed to have been given if mailed by
      certified mail in a postage-prepaid envelope addressed to the respective
      party as follows, unless any such party has notified the other party
      hereto that notices thereafter intended for such party shall be mailed to
      some other address, in which event notices thereafter shall be addressed
      to such party at the address designated in such request:

             Authorized Person; (ii) a telephonic or other oral communication
             from a person the Custodian reasonably believes to be an
             Authorized Person; or (iii) a communication effected directly
             between an electro-mechanical or electronic device or system

             by the appropriate Fund by tested telex or in writing in the
             manner set forth in clause (i) above, but the lack of such
             confirmation shall in no way affect any action taken by the
             Custodian in reliance upon such oral Instructions prior to the
             Custodian's receipt of such confirmation.  Each Fund authorizes
             the Custodian to record any and all telephonic or other oral
             Instructions communicated to the Custodian.

     (c)(2)  "Special Instructions", as used herein, shall mean Instructions
             countersigned or confirmed in writing by the Treasurer or any
             Assistant Treasurer of a Fund or any other person designated by
             the Treasurer of such Fund in writing, which countersignature or
             confirmation shall be included on the same instrument containing
             the Instructions or on a separate instrument relating thereto.

     (c)(3)  Instructions and Special Instructions shall be delivered to the
             Custodian at the address and/or telephone, facsimile transmission
             or telex number agreed upon from time to time by the Custodian and
             each Fund.

     (c)(4)  Where appropriate, Instructions and Special Instructions shall be
             continuing instructions.

3.   DELIVERY OF CORPORATE DOCUMENTS.

     Each of the parties to this Agreement represents that its execution does
     not violate any of the provisions of its respective charter, articles of
     incorporation, articles of association or bylaws and all required
     corporate action to authorize the execution and delivery of this Agreement
     has been taken.

     Each Fund has furnished the Custodian with copies, properly certified or
     authenticated, with all amendments or supplements thereto, of the
     following documents:

     (a)     Certificate of Incorporation (or equivalent document) of the Fund
             as in effect on the date hereof;

     (b)     By-Laws of the Fund as in effect on the date hereof;

     (c)     Resolutions of the Board of Directors of the Fund appointing the
             Custodian and approving the form of this Agreement; and

     (d)     The Fund's current prospectus and statements of additional
             information.





                                       2
<PAGE>   6


     Each Fund shall promptly furnish the Custodian with copies of any updates,
     amendments or supplements to the foregoing documents.

     In addition, each Fund has delivered or will promptly deliver to the
     Custodian, copies of the Resolution(s) of its Board of Directors or
     Trustees and all amendments or supplements thereto, properly certified or
     authenticated, designating certain officers or employees of each such Fund
     who will have continuing authority to certify to the Custodian:  (a) the
     names, titles, signatures and scope of authority of all persons authorized
     to give Instructions or any other notice, request, direction, instruction,
     certificate or instrument on behalf of each Fund, and (b) the names,
     titles and signatures of those persons authorized to countersign or
     confirm Special Instructions on behalf of each Fund (in both cases
     collectively, the "Authorized Persons" and individually, an "Authorized
     Person").  Such Resolutions and certificates may be accepted and relied
     upon by the Custodian as conclusive evidence of the facts set forth
     therein and shall be considered to be in full force and effect until
     delivery to the Custodian of a similar Resolution or certificate to the
     contrary.  Upon delivery of a certificate which deletes or does not
     include the name(s) of a person previously authorized to give Instructions
     or to countersign or confirm Special Instructions, such persons shall no
     longer be considered an Authorized Person authorized to give Instructions
     or to countersign or confirm Special Instructions.  Unless the certificate
     specifically requires that the approval of anyone else will first have
     been obtained, the Custodian will be under no obligation to inquire into
     the right of the person giving such Instructions or Special Instructions
     to do so.  Notwithstanding any of the foregoing, no Instructions or
     Special Instructions received by the Custodian from a Fund will be deemed
     to authorize or permit any director, trustee, officer, employee, or agent
     of such Fund to withdraw any of the Assets of such Fund upon the mere
     receipt of such authorization, Special Instructions or Instructions from
     such director, trustee, officer, employee or agent.

4.   POWERS AND DUTIES OF CUSTODIAN AND DOMESTIC SUBCUSTODIAN.

     Except for Assets held by any Subcustodian appointed pursuant to Sections
     5(b), (c), or (d) of this Agreement, the Custodian shall have and perform
     the powers and duties hereinafter set forth in this Section 4.  For
     purposes of this Section 4 all references to powers and duties of the
     "Custodian" shall also refer to any Domestic Subcustodian appointed
     pursuant to Section 5(a).

     (a)     Safekeeping.

             The Custodian will keep safely the Assets of each Fund which are
             delivered to it from time to time.  The Custodian shall not be
             responsible for any property of a Fund held or received by such
             Fund and not delivered to the Custodian.

     (b)     Manner of Holding Securities.

             (1)   The Custodian shall at all times hold Securities of each
                   Fund either:  (i) by physical possession of the share
                   certificates or other instruments representing such
                   Securities in registered or bearer form; or (ii) in
                   book-entry form by a Securities System (as hereinafter
                   defined) in accordance with the provisions of sub-paragraph
                   (3) below.

             (2)   The Custodian may hold registrable portfolio Securities
                   which have been delivered to it in physical form, by
                   registering the same in the name of the appropriate Fund or
                   its nominee, or in the name of the Custodian or its nominee,
                   for whose actions such Fund and Custodian, respectively,
                   shall be fully responsible.  Upon the receipt of
                   Instructions, the Custodian shall hold such Securities in
                   street certificate form, so called, with or without any
                   indication of fiduciary capacity.  However, unless it
                   receives Instructions to the contrary, the Custodian will
                   register all such portfolio Securities in the name of the
                   Custodian's authorized nominee.  All such Securities shall
                   be held in an account of the Custodian containing only
                   assets of the appropriate Fund or only assets held by the
                   Custodian as a fiduciary, provided that the records of the
                   Custodian shall indicate at all times the Fund or other
                   customer for which such Securities are held in such accounts
                   and the respective interests therein.

             (3)   The Custodian may deposit and/or maintain domestic
                   Securities owned by a Fund in, and each Fund hereby approves
                   use of: (a) The Depository Trust Company; (b) The
                   Participants Trust Company; and (c) any book-entry system as
                   provided in (i) Subpart 0 of Treasury Circular No. 300, 31
                   CFR 306.115, (ii) Subpart B of Treasury Circular Public Debt
                   Series No.  27-76, 31 CFR 350.2, or (iii) the book-entry
                   regulations of federal agencies substantially in the form of
                   31 CFR 306.115.  Upon the receipt of Special Instructions,
                   the Custodian may deposit and/or maintain domestic
                   Securities owned by a Fund in any other domestic clearing
                   agency registered with the Securities and Exchange
                   Commission ("SEC") under Section 17A of the Securities
                   Exchange Act of 1934 (or as may otherwise be authorized by
                   the SEC to serve in the capacity of depository or clearing
                   agent for the Securities or other assets of investment
                   companies) which acts as a Securities depository.  Each of
                   the foregoing shall be referred to in this Agreement as a
                   "Securities System", and all such Securities Systems shall
                   be listed on the attached Appendix A.  Use of a Securities
                   System shall be in accordance with applicable Federal
                   Reserve Board and SEC rules and regulations, if any, and
                   subject to the following provisions:

                    (i)   The Custodian may deposit the Securities directly or
                          through one or more agents or Subcustodians which are
                          also qualified to act as custodians for investment
                          companies.

                   (ii)   The Custodian shall deposit and/or maintain the
                          Securities in a Securities System, provided that such
                          Securities are represented in an account ("Account")
                          of the Custodian in the Securities System that
                          includes only assets held by the Custodian as a
                          fiduciary, custodian or otherwise for customers.

                  (iii)   The books and records of the Custodian shall at all
                          times identify those Securities belonging to any one
                          or more Funds which are maintained in a Securities
                          System.

                   (iv)   The Custodian shall pay for Securities purchased for
                          the account of a Fund only upon (a) receipt of advice
                          from the Securities System that such Securities have
                          been transferred to the Account of the Custodian in
                          accordance with the rules of the Securities System,
                          and (b) the making of an entry on the records of the
                          Custodian to reflect such payment and transfer for
                          the account of such Fund.  The Custodian shall
                          transfer Securities sold for the account of a Fund
                          only upon (a) receipt of advice from the Securities
                          System that payment for such Securities has been
                          transferred to the Account of the Custodian in
                          accordance with the rules of the Securities System,
                          and (b) the making of an entry on the records of the
                          Custodian to reflect such transfer and payment for
                          the account of such Fund.  Copies of all advices from
                          the Securities System relating to transfers of
                          Securities for the account of a Fund shall be
                          maintained for such Fund by the Custodian.  The
                          Custodian shall deliver to a Fund on the next
                          succeeding business day daily transaction reports
                          which shall include each day's transactions in the
                          Securities System for the account of such Fund.  Such
                          transaction reports shall be delivered to such Fund
                          or any agent designated by such Fund pursuant to
                          Instructions, by computer or in such other manner as
                          such Fund and Custodian may agree.

                    (v)   The Custodian shall, if requested by a Fund pursuant
                          to Instructions, provide such Fund with reports
                          obtained by the Custodian or any Subcustodian with
                          respect to a Securities System's accounting system,
                          internal accounting control and procedures for
                          safeguarding Securities deposited in the Securities
                          System.

                   (vi)   Upon receipt of Special Instructions, the Custodian
                          shall terminate the use of any Securities System on
                          behalf of a Fund as promptly as practicable and shall
                          take all actions reasonably practicable to safeguard
                          the Securities of such Fund maintained with such
                          Securities System.

     (c)     Free Delivery of Assets.

             Notwithstanding any other provision of this Agreement and except
             as provided in Section 3 hereof, the Custodian, upon receipt of
             Special Instructions, will undertake to make free delivery of
             Assets, provided such Assets are on hand and available, in
             connection with a Fund's transactions and to transfer such Assets
             to such broker, dealer, Subcustodian, bank, agent, Securities
             System or otherwise as specified in such Special Instructions.

     (d)     Exchange of Securities.

             Upon receipt of Instructions, the Custodian will exchange
             portfolio Securities held by it for a Fund for other Securities or
             cash paid in connection with any reorganization, recapitalization,
             merger, consolidation, or conversion of convertible Securities,
             and will deposit any such Securities in accordance with the terms
             of any reorganization or protective plan.

             Without Instructions, the Custodian is authorized to exchange
             Securities held by it in temporary form for Securities in
             definitive form, to surrender Securities for transfer into a name
             or nominee name as permitted in Section 4(b)(2), to effect an
             exchange of shares in a stock split or when the par value of the
             stock is changed, to sell any fractional shares, and, upon
             receiving payment therefor, to surrender bonds or other Securities
             held by it at maturity or call.

     (e)     Purchase of Assets.

             (1)   Securities Purchases.  In accordance with Instructions,
                   the Custodian shall, with respect to a purchase of
                   Securities, pay for such Securities out of monies held
                   for a Fund's account for which the purchase was made, but
                   only insofar as monies are available therein for such
                   purpose, and receive the portfolio Securities so
                   purchased.  Unless the Custodian has received Special
                   Instructions to the contrary, such payment will be made
                   only upon receipt of Securities by the Custodian, a
                   clearing corporation of a national Securities exchange of
                   which the Custodian is a member, or a Securities System
                   in accordance with the provisions of Section 4(b)(3)
                   hereof.  Notwithstanding the foregoing, upon receipt of
                   Instructions:  (i) in connection with a repurchase
                   agreement, the Custodian may release funds to a
                   Securities System prior to the receipt of advice from the
                   Securities System that the Securities underlying such
                   repurchase agreement have been transferred by book-entry
                   into the Account maintained with such Securities System
                   by the Custodian, provided that the Custodian's
                   instructions to the Securities System require that the
                   Securities System may make payment of such funds to the
                   other party to the repurchase agreement only upon
                   transfer by book-entry of the Securities underlying the
                   repurchase agreement into such Account; (ii) in the case
                   of Interest Bearing Deposits, currency deposits, and

                   other deposits, foreign exchange transactions, futures
                   contracts or options, pursuant to Sections 4(g), 4(h),
                   4(1), and 4(m) hereof, the Custodian may make payment
                   therefor before receipt of an advice of transaction; and
                   (iii) in the case of Securities as to which payment for
                   the Security and receipt of the instrument evidencing the
                   Security are under generally accepted trade practice or
                   the terms of the instrument representing the Security
                   expected to take place in different locations or through
                   separate parties, such as commercial paper which is
                   indexed to foreign currency exchange rates, derivatives
                   and similar Securities, the Custodian may make payment
                   for such Securities prior to delivery thereof in
                   accordance with such generally accepted trade practice or
                   the terms of the instrument representing such Security.
                   
             (2)   Other Assets Purchased.  Upon receipt of Instructions and
                   except as otherwise provided herein, the Custodian shall pay
                   for and receive other Assets for the account of a Fund as
                   provided in Instructions.

     (f)     Sales of Assets.

             (1)   Securities Sold.  In accordance with Instructions, the
                   Custodian will, with respect to a sale, deliver or cause to
                   be delivered the Securities thus designated as sold to the
                   broker or other person specified in the Instructions
                   relating to such sale.  Unless the Custodian has received
                   Special Instructions to the contrary, such delivery shall be
                   made only upon receipt of payment therefor in the form of:
                   (a) cash, certified check, bank cashier's check, bank
                   credit, or bank wire transfer; (b) credit to the account of
                   the Custodian with a clearing corporation of a national
                   Securities exchange of which the Custodian is a member; or
                   (c) credit to the Account of the Custodian with a Securities
                   System, in accordance with the provisions of Section 4(b)(3)
                   hereof.  Notwithstanding the foregoing, Securities held in
                   physical form may be delivered and paid for in accordance
                   with "street delivery custom" to a broker or its clearing
                   agent, against delivery to the Custodian of a receipt for
                   such Securities, provided that the Custodian shall have
                   taken reasonable steps to ensure prompt collection of the

             collectively, as "ADRs"), against a written receipt therefor
             adequately describing such Securities and written evidence
             satisfactory to the organization surrendering the same that the

<PAGE>   13

             acknowledged receipt of instructions to cause its depository to
             deliver the Securities underlying such ADRs in accordance with
             such instructions.

     (k)     Corporate Actions, Put Bonds, Called Bonds, Etc.

             or trustee thereof (or to the agent of such issuer or trustee) for
             the purpose of exercise or sale, provided that the new Securities,
             cash or other Assets, if any, acquired as a result of such actions
             are to be delivered to the Custodian; and (b) deposit Securities
             upon invitations for tenders thereof, provided that the
             consideration for such Securities is to be paid or delivered to
             the Custodian, or the tendered Securities are to be returned to
             the Custodian.

             Notwithstanding any provision of this Agreement to the contrary,
             the Custodian shall take all necessary action, unless otherwise
             directed to the contrary in Instructions, to comply with the terms
             of all mandatory or compulsory exchanges, calls, tenders,
             redemptions, or similar rights of security ownership, and shall
             notify the appropriate Fund of such action in writing by facsimile
             transmission or in such other manner as such Fund and Custodian
             may agree in writing.

             The Fund agrees that if it gives an Instruction for the
             performance of an act on the last permissible date of a period
             established by any optional offer or on the last permissible date
             for the performance of such act, the Fund shall hold the Bank

     (l)     Interest Bearing Deposits.

             Upon receipt of Instructions directing the Custodian to purchase
             interest bearing fixed term and call deposits (hereinafter
             referred to, collectively, as "Interest Bearing Deposits") for the
             account of a Fund, the Custodian shall purchase such Interest
             Bearing Deposits in the name of such Fund with such banks or trust
             companies, including the Custodian, any Subcustodian or any
             subsidiary or affiliate of the Custodian (hereinafter referred to
             as "Banking Institutions"), and in such amounts as such Fund may
             direct pursuant to Instructions.  Such Interest Bearing Deposits
             may be denominated in U.S. dollars or other currencies, as such

             Deposits issued by the Custodian shall be that of a U.S. bank for
             a similar deposit.  With respect to Interest Bearing Deposits
             other than those issued by the Custodian, (a) the Custodian shall
             be responsible for the collection of income and the transmission
             of cash to and from such accounts; and (b) the Custodian shall
             have no duty with respect to the selection of the Banking
             Institution or for the failure of such Banking Institution to pay
             upon demand.

             (1)   Upon receipt of Instructions, the Custodian shall settle
                   foreign exchange contracts or options to purchase and sell
                   foreign currencies for spot and future delivery on behalf of
                   and for the account of a Fund with such currency brokers or
                   Banking Institutions as such Fund may determine and direct
                   pursuant to Instructions.  Each Fund accepts full
                   responsibility for its use of third party foreign exchange
                   brokers and for execution of said foreign exchange contracts
                   and understands that the Fund shall be responsible for any
                   and all costs and interest charges which may be incurred as
                   a result of the failure or delay of its third party broker
                   to deliver foreign exchange.  The Custodian shall have no
                   responsibility with respect to the selection of the currency
                   brokers or Banking Institutions with which a Fund deals or,
                   so long as the Custodian acts in accordance with
                   Instructions, for the failure of such brokers or Banking
                   Institutions to comply with the terms of any contract or
                   option.

             (2)   Notwithstanding anything to the contrary contained herein,
                   upon receipt of Instructions the Custodian may, in
                   connection with a foreign exchange contract, make free
                   outgoing payments of cash in the form of U.S. Dollars or
                   foreign currency prior to receipt of confirmation of such
                   foreign exchange contract or confirmation that the
                   countervalue currency completing such contract has been
                   delivered or received.

     (n)     Pledges or Loans of Securities.

             (1)   Upon receipt of Instructions from a Fund, the Custodian will
                   release or cause to be released Securities held in custody
                   to the pledgees designated in such Instructions by way of
                   pledge or hypothecation to secure loans incurred by such
                   Fund with various lenders including but not limited to UMB
                   Bank, n.a.; provided, however, that the Securities shall be
                   released only upon payment to the Custodian of the monies
                   borrowed, except that in cases where additional collateral
                   is required to secure existing borrowings, further
                   Securities may be released or delivered, or caused to be
                   released or delivered for that purpose upon receipt of
                   Instructions.  Upon receipt of Instructions, the Custodian
                   will pay, but only from funds available for such purpose,
                   any such loan upon re-delivery to it of the Securities
                   pledged or hypothecated therefor and upon surrender of the
                   note or notes evidencing such loan.  In lieu of delivering
                   collateral to a pledgee, the Custodian, on the receipt of
                   Instructions, shall transfer the pledged Securities to a
                   segregated account for the benefit of the pledgee.

                   separate Securities Lending Agreement, the Custodian will

                   designated in such Instructions and may, except as otherwise
                   provided below, deliver such Securities prior to the receipt
                   of collateral, if any, for such borrowing, provided that, in
                   case of loans of Securities held by a Securities System that
                   are secured by cash collateral, the Custodian's instructions
                   to the Securities System shall require that the Securities
                   System deliver the Securities of the appropriate Fund to the
                   borrower thereof only upon receipt of the collateral for
                   such borrowing.  The Custodian shall have no responsibility
                   or liability for any loss arising from the delivery of
                   Securities prior to the receipt of collateral.  Upon receipt
                   of Instructions and the loaned Securities, the Custodian
                   will release the collateral to the borrower.

     (o)     Stock Dividends, Rights, Etc.

             The Custodian shall receive and collect all stock dividends,
             rights, and other items of like nature and, upon receipt of

             The Custodian will, in general, attend to all routine and
             mechanical matters in accordance with industry standards in
             connection with the sale, exchange, substitution, purchase,
             transfer, or other dealings with Securities or other property of
             each Fund except as may be otherwise provided in this Agreement or
             directed from time to time by Instructions from any particular
             Fund.  The Custodian may also make payments to itself or others
             from the Assets for disbursements and out-of-pocket expenses
             incidental to handling Securities or other similar items relating
             to its duties under this Agreement, provided that all such
             payments shall be accounted for to the appropriate Fund.

     (q)     Collections.

             The Custodian shall (a) collect amounts due and payable to each
             Fund with respect to portfolio Securities and other Assets;
             (b) promptly credit to the account of each Fund all income and

             Custodian and any particular Fund; (c) promptly endorse and
             deliver any instruments required to effect such collection; and
             (d) promptly execute ownership and other certificates and

             with the transfer of such Securities or other Assets; provided,
             however, that with respect to portfolio Securities registered in
             so-called street name, or physical Securities with variable
             interest rates, the Custodian shall use its

             portfolio Securities or other Assets is not received by the
             Custodian when due.  The Custodian shall not be responsible for
             the collection of amounts due and payable with respect to

             such bank account(s) shall be in the name of the Custodian or a
             nominee thereof, for the account of one or more Funds, and shall
             be subject only to draft or order of the Custodian.  The
             responsibilities of the Custodian to any one or more such Funds
             for deposits accepted on the Custodian's books shall be that of a
             U.S. bank for a similar deposit.

     (s)     Dividends, Distributions and Redemptions.

             To enable each Fund to pay dividends or other distributions to
             shareholders of each such Fund and to make payment to shareholders
             who have requested repurchase or redemption of their shares of

             any bank or trust company designated by each such Fund in such
             Instructions.  In the case of Securities, the Custodian shall,
             upon the receipt of Special Instructions, make such transfer to
             any entity or account designated by each such Fund in such Special
             Instructions.

             received for shares issued or sold from time to time by each Fund,
             and shall credit such funds to the account of the appropriate

             Fund by facsimile transmission or in such other manner as such
             Fund and the Custodian shall agree.  Upon receipt of Instructions,
             the Custodian shall:  (a) deliver all federal funds received by
             the Custodian in payment for shares as may be set forth in such
             Instructions and at a time agreed upon between the Custodian and
             such Fund; and (b) make federal funds available to a Fund as of
             specified times agreed upon from time to time by such Fund and the
             Custodian, in the amount of checks received in payment for shares
             which are deposited to the accounts of such Fund.

             Upon receipt of Instructions, the Custodian shall pay, or cause to

5.   SUBCUSTODIANS.

     From time to time, in accordance with the relevant provisions of this
     Agreement, the Custodian may appoint one or more Domestic Subcustodians,
     Foreign Subcustodians, Special Subcustodians, or Interim Subcustodians (as
     each are hereinafter defined) to act on behalf of any one or more Funds.
     A Domestic Subcustodian, in accordance with the provisions of this
     Agreement, may also appoint a Foreign Subcustodian, Special Subcustodian,
     or Interim Subcustodian to act on behalf of any one or more Funds.  For
     purposes of this Agreement, all Domestic Subcustodians, Foreign
     Subcustodians, Special Subcustodians and Interim Subcustodians shall be
     referred to collectively as "Subcustodians".

     (a)     Domestic Subcustodians.

             The Custodian may, at any time and from time to time, appoint any
             bank as defined in Section 2(a)(5) of the 1940 Act or any trust
             company or other entity, any of which meet the requirements of a
             custodian under Section 17(f) of the 1940 Act and the rules and
             regulations thereunder, to act for the Custodian on behalf of any

             of such Fund(s) and performing other functions of the Custodian
             within the United States (a "Domestic Subcustodian").  Each Fund
             shall approve in writing the appointment of the proposed Domestic
             Subcustodian; and the Custodian's appointment of any such Domestic
             Subcustodian shall not be effective without such prior written
             approval of the Fund(s).  Each such duly approved Domestic
             Subcustodian shall be listed on Appendix A attached hereto, as it
             may be amended, from time to time.

     (b)     Foreign Subcustodians.

             The Custodian may at any time appoint, or cause a Domestic
             Subcustodian to appoint, any bank, trust company or other entity
             meeting the requirements of an "eligible foreign custodian" under
             Section 17(f) of the 1940 Act and the rules and regulations
             thereunder to act for the Custodian on behalf of any one or more
             Funds as a subcustodian or sub-subcustodian (if appointed by a
             Domestic Subcustodian)





                                       15

             for purposes of holding Assets of the Fund(s) and performing other
             functions of the Custodian in countries other than the United
             States of America (hereinafter referred to as a "Foreign
             Subcustodian" in the context of either a subcustodian or a
             sub-subcustodian); provided that the Custodian shall have obtained
             written confirmation from each Fund of the approval of the Board
             of Directors or other governing body of each such Fund (which
             approval may be withheld in the sole discretion of such Board of
             Directors or other governing body or entity) with respect to
             (i) the identity of any proposed Foreign Subcustodian (including
             branch designation), (ii) the country or countries in which, and
             the securities depositories or clearing agencies (hereinafter
             "Securities Depositories and Clearing Agencies"), if any, through
             which, the Custodian or any proposed Foreign Subcustodian is
             authorized to hold Securities and other Assets of each such Fund,
             and (iii) the form and terms of the subcustodian agreement to be
             entered into with such proposed Foreign Subcustodian.  Each such
             duly approved Foreign Subcustodian and the countries where and the
             Securities Depositories and Clearing Agencies through which they
             may hold Securities and other Assets of the Fund(s) shall be
             listed on Appendix A attached hereto, as it may be amended, from
             time to time.  Each Fund shall be responsible for informing the
             Custodian sufficiently in advance of a proposed investment which
             is to be held in a country in which no Foreign Subcustodian is
             authorized to act, in order that there shall be sufficient time
             for the Custodian, or any Domestic Subcustodian, to effect the
             appropriate arrangements with a proposed Foreign Subcustodian,
             including obtaining approval as provided in this Section 5(b).  In
             connection with the appointment of any Foreign Subcustodian, the
             Custodian shall, or shall cause the Domestic Subcustodian to,
             enter into a subcustodian agreement with the Foreign Subcustodian
             in form and substance approved by each such Fund.  The Custodian
             shall not consent to the amendment of, and shall cause any
             Domestic Subcustodian not to consent to the amendment of, any
             agreement entered into with a Foreign Subcustodian, which
             materially affects any Fund's rights under such agreement, except
             upon prior written approval of such Fund pursuant to Special
             Instructions.

     (c)     Interim Subcustodians.

             Notwithstanding the foregoing, in the event that a Fund shall
             invest in an Asset to be held in a country in which no Foreign
             Subcustodian is authorized to act, the Custodian shall notify such
             Fund in writing by facsimile transmission or in such other manner
             as such Fund and the Custodian shall agree in writing of the
             unavailability of an approved Foreign Subcustodian in such
             country; and upon the receipt of Special Instructions from such
             Fund, the Custodian shall, or shall cause its Domestic
             Subcustodian to, appoint or approve an entity (referred to herein
             as an "Interim Subcustodian") designated in such Special
             Instructions to hold such Security or other Asset.

     (d)     Special Subcustodians.

             Upon receipt of Special Instructions, the Custodian shall on
             behalf of a Fund, appoint one or more banks, trust companies or
             other entities designated in such Special Instructions to act for
             the Custodian on behalf of such Fund as a subcustodian for
             purposes of:  (i) effecting third-party repurchase transactions
             with banks, brokers, dealers or other entities through the use of
             a common custodian or subcustodian; (ii) providing depository and
             clearing agency services with respect to certain variable rate
             demand note Securities, (iii) providing depository and clearing
             agency services with respect to dollar denominated Securities, and
             (iv) effecting any other transactions designated by such Fund in
             such Special Instructions.  Each such designated subcustodian
             (hereinafter referred to as a "Special Subcustodian") shall be
             listed on Appendix A attached hereto, as it may be amended from
             time to time.  In connection with the appointment of any Special
             Subcustodian, the Custodian shall enter into a subcustodian
             agreement with the Special Subcustodian in form and substance
             approved by the appropriate Fund in Special Instructions.  The
             Custodian shall not amend any subcustodian agreement entered into
             with a Special Subcustodian, or waive any rights under such
             agreement, except upon prior approval pursuant to Special
             Instructions.

     (e)     Termination of a Subcustodian.

             The Custodian may, at any time in its discretion upon notification
             to the appropriate Fund(s), terminate any Subcustodian of such
             Fund(s) in accordance with the termination provisions under the
             applicable subcustodian agreement, and upon the receipt of Special
             Instructions, the Custodian will terminate any Subcustodian in
             accordance with the termination provisions under the applicable
             subcustodian agreement.

     (f)     Certification Regarding Foreign Subcustodians.

             Upon request of a Fund, the Custodian shall deliver to such Fund a
             certificate stating:  (i) the identity of each Foreign
             Subcustodian then acting on behalf of the Custodian; (ii) the
             countries in which and the Securities Depositories and Clearing
             Agencies through which each such Foreign Subcustodian is then
             holding cash, Securities and other Assets of such Fund; and
             (iii) such other information as may be requested by such Fund, and
             as the Custodian shall be reasonably able to obtain, to evidence
             compliance with rules and regulations under the 1940 Act.

6.   STANDARD OF CARE.

             The Custodian shall be liable to a Fund for all losses, damages
             and reasonable costs and expenses suffered or incurred by such
             Fund resulting from the gross





                                       17
<PAGE>   21

             negligence or willful misfeasance of the Custodian; provided,
             however, in no event shall the Custodian be liable for special,
             indirect or consequential damages arising under or in connection
             with this Agreement.

             liability in respect of any loss, damage or expense suffered by a
             Fund, insofar as such loss, damage or expense arises from the

             reliance upon records that were maintained for such Fund by
             entities other than the Custodian or any Domestic Subcustodian

             The Custodian shall be liable for the acts or omissions of any

             omissions were performed by the Custodian itself.

     (b)     Liability for Acts and Omissions of Foreign Subcustodians.

             The Custodian shall be liable to a Fund for any loss or damage to

             occasioned by the actions or omissions of a Securities System,
             Interim Subcustodian, Special Subcustodian, or Securities
             Depository and Clearing Agency unless such loss, damage or expense
             is caused by, or results from, the gross negligence or willful
             misfeasance of the Custodian.

     (d)     Defaults or Insolvencies of Brokers, Banks, Etc.

             The Custodian shall not be liable for any loss, damage or expense
             suffered or incurred by any Fund resulting from or occasioned by
             the actions, omissions, neglects, defaults or insolvency of any
             broker, bank, trust company or any other person with whom the
             Custodian may deal (other than any of such entities acting as a
             Subcustodian, Securities System or Securities Depository and
             Clearing Agency, for whose actions the liability of the Custodian
             is set out elsewhere in this Agreement) unless such loss, damage
             or expense is caused by, or results from, the gross negligence or
             willful misfeasance of the Custodian.

     (e)     Reimbursement of Expenses.

             Each Fund agrees to reimburse the Custodian for all out-of-pocket
             expenses incurred by the Custodian in connection with this
             Agreement, but excluding salaries and usual overhead expenses.

8.   INDEMNIFICATION.

     (a)     Indemnification by Fund.

             Subject to the limitations set forth in this Agreement, each Fund
             agrees to indemnify and hold harmless the Custodian and its
             nominees from all losses, damages and expenses (including
             attorneys' fees) suffered or incurred by the Custodian or its
             nominee caused by or arising from actions taken by the Custodian,
             its employees or agents in the performance of its duties and
             obligations under this Agreement, including, but not limited to,
             any indemnification obligations undertaken by the Custodian under
             any relevant subcustodian agreement; provided, however, that such
             indemnity shall not apply to the extent the Custodian is liable
             under Sections 6 or 7 hereof.

             If any Fund requires the Custodian to take any action with respect
             to Securities, which action involves the payment of money or which
             may, in the opinion of the Custodian, result in the Custodian or
             its nominee assigned to such Fund being liable for the payment of
             money or incurring liability of some other form, such Fund, as a
             prerequisite to requiring the Custodian to take such action, shall
             provide indemnity to the Custodian in an amount and form
             satisfactory to it.

     (b)     Indemnification by Custodian.

             Subject to the limitations set forth in this Agreement and in
             addition to the obligations provided in Sections 6 and 7, the
             Custodian agrees to indemnify and hold harmless each Fund from all
             losses, damages and expenses suffered or incurred by each such
             Fund caused by the gross negligence or willful misfeasance of the
             Custodian.

9.   ADVANCES.

     In the event that, pursuant to Instructions, the Custodian or any
     Subcustodian, Securities System, or Securities Depository or Clearing
     Agency acting either directly or indirectly under agreement with the
     Custodian (each of which for purposes of this Section 9 shall be referred
     to as "Custodian"), makes any payment or transfer of funds on behalf of
     any Fund as to which there would be, at the close of business on the date
     of such payment or transfer, insufficient funds held by the Custodian on
     behalf of any such Fund, the Custodian may, in its discretion without
     further Instructions, provide an advance ("Advance") to any such Fund in
     an amount sufficient to allow the completion of the transaction by reason
     of which such payment or transfer of funds is to be made.  In addition, in
     the event the Custodian is directed by Instructions to make any payment or
     transfer of funds on behalf of any Fund as to which it is subsequently
     determined that such Fund has overdrawn its cash account with the
     Custodian as of the close of business on the date of such payment or
     transfer, said overdraft shall constitute an Advance.  Any





                                       21
<PAGE>   25

     Advance shall be payable by the Fund on behalf of which the Advance was
     made on demand by Custodian, unless otherwise agreed by such Fund and the
     Custodian, and shall accrue interest from the date of the Advance to the
     date of payment by such Fund to the Custodian at a rate agreed upon in
     writing from time to time by the Custodian and such Fund.  It is
     understood that any transaction in respect of which the Custodian shall
     have made an Advance, including but not limited to a foreign exchange
     contract or transaction in respect of which the Custodian is not acting as
     a principal, is for the account of and at the risk of the Fund on behalf
     of which the Advance was made, and not, by reason of such Advance, deemed
     to be a transaction undertaken by the Custodian for its own account and
     risk.  The Custodian and each of the Funds which are parties to this
     Agreement acknowledge that the purpose of Advances is to finance
     temporarily the purchase or sale of Securities for prompt delivery in
     accordance with the settlement terms of such transactions or to meet
     emergency expenses not reasonably foreseeable by a Fund.  The Custodian
     shall promptly notify the appropriate Fund of any Advance.  Such
     notification shall be sent by facsimile transmission or in such other
     manner as such Fund and the Custodian may agree.

10.  LIENS.

     The Bank shall have a lien on the Property in the Custody Account to
     secure payment of fees and expenses for the services rendered under this
     Agreement.  If the Bank advances cash or securities to the Fund for any
     purpose or in the event that the Bank or its nominee shall incur or be
     assessed any taxes, charges, expenses, assessments, claims or liabilities
     in connection with the performance of its duties hereunder, except such as
     may arise from its or its nominee's negligent action, negligent failure to
     act or willful misconduct, any Property at any time held for the Custody
     Account shall be security therefor and the Fund hereby grants a security
     interest therein to the Bank.  The Fund shall promptly reimburse the Bank
     for any such advance of cash or securities or any such taxes, charges,
     expenses, assessments, claims or liabilities upon request for payment, but
     should the Fund fail to so reimburse the Bank, the Bank shall be entitled
     to dispose of such Property to the extent necessary to obtain
     reimbursement.  The Bank shall be entitled to debit any account of the
     Fund with the Bank including, without limitation, the Custody Account, in
     connection with any such advance and any interest on such advance as the
     Bank deems reasonable.

11.  COMPENSATION.

     Each Fund will pay to the Custodian such compensation as is agreed to in
     writing by the Custodian and each such Fund from time to time.  Such
     compensation, together with all amounts for which the Custodian is to be
     reimbursed in accordance with Section 7(e), shall be billed to each such
     Fund and paid in cash to the Custodian.

12.  POWERS OF ATTORNEY.

     Upon request, each Fund shall deliver to the Custodian such proxies,
     powers of attorney or other instruments as may be reasonable and necessary
     or desirable in connection with





                                       22
<PAGE>   26

     the performance by the Custodian or any Subcustodian of their respective
     obligations under this Agreement or any applicable subcustodian agreement.

13.  TERMINATION AND ASSIGNMENT.

     Any Fund or the Custodian may terminate this Agreement by notice in
     writing, delivered or mailed, postage prepaid (certified mail, return
     receipt requested) to the other not less than 90 days prior to the date
     upon which such termination shall take effect.  Upon termination of this
     Agreement, the appropriate Fund shall pay to the Custodian such fees as
     may be due the Custodian hereunder as well as its reimbursable
     disbursements, costs and expenses paid or incurred.  Upon termination of
     this Agreement, the Custodian shall deliver, at the terminating party's
     expense, all Assets held by it hereunder to the appropriate Fund or as
     otherwise designated by such Fund by Special Instructions.  Upon such
     delivery, the Custodian shall have no further obligations or liabilities
     under this Agreement except as to the final resolution of matters relating
     to activity occurring prior to the effective date of termination.

     This Agreement may not be assigned by the Custodian or any Fund without
     the respective consent of the other, duly authorized by a resolution by
     its Board of Directors or Trustees.

14.  ADDITIONAL FUNDS.

     An additional Fund or Funds may become a party to this Agreement after the
     date hereof by an instrument in writing to such effect signed by such Fund
     or Funds and the Custodian.  If this Agreement is terminated as to one or
     more of the Funds (but less than all of the Funds) or if an additional
     Fund or Funds shall become a party to this Agreement, there shall be
     delivered to each party an Appendix B or an amended Appendix B, signed by
     each of the additional Funds (if any) and each of the remaining Funds as
     well as the Custodian, deleting or adding such Fund or Funds, as the case
     may be.  The termination of this Agreement as to less than all of the
     Funds shall not affect the obligations of the Custodian and the remaining
     Funds hereunder as set forth on the signature page hereto and in Appendix
     B as revised from time to time.

15.  NOTICES.

     As to each Fund, notices, requests, instructions and other writings
     delivered to The Security Benefit Group of Companies, 700 Harrison,
     Topeka, KS 66636-0001 , postage prepaid, or to such other address as any
     particular Fund may have designated to the Custodian in writing, shall be
     deemed to have been properly delivered or given to a Fund.

     Notices, requests, instructions and other writings delivered to the
     Securities Administration Department of the Custodian at its office at 928
     Grand Avenue, Kansas City, Missouri, or mailed postage prepaid, to the
     Custodian's Securities Administration Department, Post Office Box 226,
     Kansas City, Missouri 64141, or to such other addresses as the Custodian
     may have designated to each Fund in writing, shall be deemed





                                       23
<PAGE>   27

     to have been properly delivered or given to the Custodian hereunder;
     provided, however, that procedures for the delivery of Instructions and
     Special Instructions shall be governed by Section 2(c) hereof..

16.  MISCELLANEOUS.

     (a)     This Agreement is executed and delivered in the State of Missouri
             and shall be governed by the laws of such state.

     (b)     All of the terms and provisions of this Agreement shall be binding
             upon, and inure to the benefit of, and be enforceable by the

     (c)     No provisions of this Agreement may be amended, modified or
             waived, in any manner except in writing, properly executed by both
             parties hereto; provided, however, Appendix A may be amended from
             time to time as Domestic Subcustodians, Foreign Subcustodians,
             Special Subcustodians, and Securities Depositories and Clearing
             Agencies are approved or terminated according to the terms of this
             Agreement.

     (d)     The captions in this Agreement are included for convenience of
             reference only, and in no way define or delimit any of the
             provisions hereof or otherwise affect their construction or
             effect.

     (e)     This Agreement shall be effective as of the date of execution
             hereof.

     (f)     This Agreement may be executed simultaneously in two or more
             counterparts, each of which will be deemed an original, but all of
             which together will constitute one and the same instrument.

                            GLOBAL CUSTODY AGREEMENT


This AGREEMENT is effective May 1, 1995, and is between THE CHASE MANHATTAN
BANK, N.A. (the "Bank") and _________________________ (the "Customer").

1.  CUSTOMER ACCOUNTS.

    The Bank agrees to establish and maintain the following accounts 
    ("Accounts"):

    (a)      A custody account in the name of the Customer ("Custody Account")
             for any and all stocks, shares, bonds, debentures, notes,
             mortgages or other obligations for the payment of money, bullion,
             coin and any certificates, receipts, warrants or other instruments
             representing rights to receive, purchase or subscribe for the same
             or evidencing or representing any other rights or interests
             therein and other similar property whether certified or
             uncertified as may be received by the Bank or its Subcustodian (as
             defined in Section 3) for the account of the Customer
             ("Securities"); and

    (b)      A deposit account in the name of the Customer ("Deposit Account")
             for any and all cash in any currency received by the Bank or its
             Subcustodian for the account of the Customer, which cash shall not
             be subject to withdrawal by draft or check.

    The Customer warrants its authority to:  1) deposit the cash and
    Securities ("Assets") received in the Accounts and 2) give Instructions
    (as defined in Section 11) concerning the Accounts.  The Bank may deliver
    securities of the same class in place of those deposited in the Custody
    Account.

    Upon written agreement between the Bank and the Customer, additional
    Accounts may be established and separately accounted for as additional
    Accounts under the terms of this Agreement.

2.  MAINTENANCE OF SECURITIES AND CASH AT BANK AND SUBCUSTODIAN LOCATIONS.

    Unless Instructions specifically require another location acceptable to
    the Bank:

    (a)      Securities will be held in the country or other jurisdiction in
             which the principal trading market for such Securities is located,
             where such Securities are to be presented for payment or where
             such Securities are acquired; and

    (b)      Cash will be credited to an account in a country or other
             jurisdiction in which such cash may be legally deposited or is the
             legal currency for the payment of public or private debts.
<PAGE>   2

    Cash may be held pursuant to Instructions in either interest or non-interest
    bearing accounts as may be available for the particular currency.  To the
    extent Instructions are issued and the Bank can comply with such
    Instructions, the Bank is authorized to maintain cash balances on deposit
    for the Customer with itself or one of its affiliates at such reasonable
    rates of interest as may from time to time be paid on such accounts, or
    in non-interest bearing accounts as the Customer may direct, if
    acceptable to the Bank.

    If the customer wishes to have any of its Assets held in the custody of
    an institution other than the established Subcustodians as defined in
    Section 3 (or their securities depositories), such arrangement must be
    authorized by a written agreement, signed by the Bank and the Customer.

3.  SUBCUSTODIANS AND SECURITIES DEPOSITORIES.

    The Bank may act under this Agreement through the subcustodians listed in
    Schedule A of this Agreement with which the Bank has entered into
    subcustodial agreements ("Subcustodians").  The Customer authorizes the
    Bank to hold Assets in the Accounts in accounts which the Bank has
    established with one or more of its branches or Subcustodians.

    The Bank and Subcustodians are authorized to hold any of the Securities
    in their account with any securities depository in which they
    participate.

    The Bank reserves the right to add new, replace or remove Subcustodians.
    The Customer will be given reasonable notice by the Bank of any amendment
    to Schedule A.  Upon request by the Customer, the Bank will identify the
    name, address and principal place of business of any Subcustodian of the
    Customer's Assets and the name and address of the governmental agency or
    other regulatory authority that supervises or regulates such
    Subcustodian.

4.  USE OF SUBCUSTODIAN.

    (a)      The Bank will identify such Assets on its books as belonging to
             the Customer.

    (b)      A Subcustodian will hold such Assets together with assets
             belonging to other customers of the Bank in accounts identified on
             such Subcustodian's books as special custody accounts for the
             exclusive benefit of customers of the Bank.

    (c)      Any Assets in the Accounts held by a Subcustodian will be subject
             only to the instructions of the Bank or its agent.  Any Securities
             held in a securities depository for the account of a Subcustodian
             will be subject only to the instructions of such Subcustodian.

    (d)      Any agreement the Bank enters into with a Subcustodian for holding
             its customer's assets shall provide that such assets will not be
             subject to any right, charge, security interest, lien or claim of
             any kind in favor of such Subcustodian except for safe custody or
             administration, and that the beneficial ownership of such assets
             will be freely transferable without the payment of money or value
             other than for safe custody





                                      1
<PAGE>   3

             or administration.  The foregoing shall not apply to the extent of
             any special agreement or arrangement made by the Customer with any
             particular Subcustodian.

5.  DEPOSIT ACCOUNT TRANSACTIONS.

    (a)      The Bank or its Subcustodians will make payments from the Deposit
             Account upon receipt of Instructions which include all information
             required by the Bank.

    (b)      In the event that any payment to be made under this Section 5
             exceeds the funds available in the Deposit Account, the Bank, in
             its discretion, may advance the Customer such excess amount which
             shall be deemed a loan payable on demand, bearing interest at the
             rate customarily charged by the Bank on similar loans.

    (c)      If the Bank credits the Deposit Account on a payable date, or at
             any time prior to actual collection and reconciliation to the
             Deposit Account, with interest, dividends, redemptions or any
             other amount due, the Customer will promptly return any such
             amount upon oral or written notification:  (i) that such amount
             has not been received in the ordinary course of business or (ii)
             that such amount was incorrectly credited.  If the Customer does
             not promptly return any amount upon such notification, the Bank
             shall be entitled, upon oral or written notification to the
             Customer, to reverse such credit by debiting the Deposit Account
             for the amount previously credited.  The Bank or its Subcustodian
             shall have no duty or obligation to institute legal proceedings,
             file a claim or a proof of claim in any insolvency proceeding or
             take any other action with respect to the collection of such
             amount, but may act for the Customer upon Instructions after
             consultation with the Customer.

6.  CUSTODY ACCOUNT TRANSACTIONS.

    (a)      Securities will be transferred, exchanged or delivered by the Bank
             or its Subcustodian upon receipt by the Bank of Instructions which
             include all information required by the Bank.  Settlement and
             payment for Securities received for and delivery of Securities out
             of, the Custody Account may be made in accordance with the
             customary or established securities trading or securities
             processing practices and procedures in the jurisdiction or market
             in which the transaction occurs, including, without limitation,
             delivery of Securities to a purchaser, dealer or their agents
             against a receipt with the expectation of receiving later payment
             and free delivery.  Delivery of Securities out of the Custody
             Account may also be made in any manner specifically required by
             Instructions acceptable to the Bank.

    (b)      The Bank, in its discretion, may credit or debit the Accounts on a
             contractual settlement date with cash or Securities with respect
             to any sale, exchange or purchase of Securities.  Otherwise, such
             transactions will be credited or debited to the Accounts on the
             date cash or Securities are actually received by the Bank and
             reconciled to the Account.

             (i)   The Bank may reverse credits or debits made to the Accounts
                   in its discretion if the related transaction fails to settle
                   within a reasonable period, determined by





                                      2
<PAGE>   4

                   the Bank in its discretion, after the contractual settlement
                   date for the related transaction.

            (ii)   If any Securities delivered pursuant to this Section 6 are
                   returned by the recipient thereof, the Bank may reverse the
                   credits and debits of the particular transaction at any
                   time.

7.  ACTIONS OF THE BANK.

    The Bank shall follow Instructions received regarding assets held in the
    Accounts.  However, until it receives Instructions to the contrary, the
    Bank will:

    (a)      Present for payment any Securities which are called, redeemed or
             retired or otherwise become payable and all coupons and other
             income items which call for payment upon presentation, to the
             extent that the Bank or Subcustodian is actually aware of such
             opportunities.

    (b)      Execute in the name of the Customer such ownership and other
             certificates as may be required to obtain payments in respect of
             Securities.

    (c)      Exchange interim receipts or temporary Securities for definitive
             Securities.

    (d)      Appoint brokers and agents for any transaction involving the
             Securities, including, without limitation, affiliates of the Bank
             or any Subcustodian.

    (e)      Issue statements to the Customer, at times mutually agreed upon,
             identifying the Assets in the Accounts.

    The Bank will send the Customer an advice or notification of any
    transfers of Assets to or from the Accounts.  Such statements, advices or
    notifications shall indicate the identity of the entity having custody of
    the Assets.  Unless the Customer sends the Bank a written exception or
    objection to any Bank statement within sixty (60) days of receipt, the
    Customer shall be deemed to have approved such statement.  In such event,
    or where the Customer has otherwise approved any such statement, the Bank
    shall, to the extent permitted by law, be released, relieved and
    discharged with respect to all matters set forth in such statement or
    reasonably implied therefrom as though it had been settled by the decree
    of a court of competent jurisdiction in an action where the Customer and
    all persons having or claiming an interest in the Customer or the
    Customer's Accounts were parties.

    All collections of funds or other property paid or distributed in respect
    of Securities in the Custody Account shall be made at the risk of the
    Customer.  The Bank shall have no liability for any loss occasioned by
    delay in the actual receipt of notice by the Bank or by its Subcustodians
    of any payment, redemption or other transaction regarding Securities in
    the Custody Account in respect of which the Bank has agreed to take any
    action under this Agreement.





                                      3

8.  CORPORATE ACTIONS; PROXIES.

    Whenever the Bank receives information concerning the Securities which
    requires discretionary action by the beneficial owner of the Securities
    (other than a proxy), such as subscription rights, bonus issues, stock
    repurchase plans and rights offerings, or legal notices or other material
    intended to be transmitted to securities holders ("Corporate Actions"),
    the Bank will give the Customer notice of such Corporate Actions to the
    extent that the Bank's central corporate actions department has actual
    knowledge of a Corporate Action in time to notify its customers.

    When a rights entitlement or a fractional interest resulting from a
    rights issue, stock dividend, stock split or similar Corporate Action is
    received which bears an expiration date, the Bank will endeavor to obtain
    Instructions from the Customer or its Authorized Person, but if
    Instructions are not received in time for the Bank to take timely action,
    or actual notice of such Corporate Action was received too late to seek
    Instructions, the Bank is authorized to sell such rights entitlement or
    fractional interest and to credit the Deposit Account with the proceeds
    or take any other action it deems, in good faith, to be appropriate in
    which case it shall be held harmless for any such action.

    The Bank will deliver proxies to the Customer or its designated agent
    pursuant to special arrangements which may have been agreed to in
    writing.  Such proxies shall be executed in the appropriate nominee name
    relating to Securities in the Custody Account registered in the name of
    such nominee, but without indicating the manner in which such proxies are
    to be voted; and where bearer Securities are involved, proxies will be
    delivered in accordance with Instructions.

9.  NOMINEES.

    Securities which are ordinarily held in registered form may be registered
    in a nominee name of the Bank, Subcustodian or securities depository, as
    the case may be.  The Bank may without notice to the Customer cause any
    such Securities to cease to be registered in the name of any such nominee
    and to be registered in the name of the Customer.  In the event that any
    Securities registered in a nominee name are called for partial redemption
    by the issuer, the Bank may allot the called portion to the respective
    beneficial holders of such class of security in any manner the Bank deems
    to be fair and equitable.  The Customer agrees to hold the Bank,
    Subcustodians, and their respective nominees harmless from any liability
    arising directly or indirectly from their status as a mere record holder
    of Securities in the Custody Account.

10. AUTHORIZED PERSONS.

    As used in this Agreement, the term "Authorized Person" means employees
    or agents including investment managers as have been designated by
    written notice from the Customer or its designated agent to act on behalf
    of the Customer under this Agreement.  Such persons shall continue to be
    Authorized Persons until such time as the Bank receives Instructions from
    the Customer or its designated agent that any such employee or agent is
    no longer an Authorized Person.





                                      4
<PAGE>   6


11. INSTRUCTIONS.
    
    The term "Instructions" means instructions of any Authorized Person
    received by the Bank, via telephone, telex, TWX, facsimile transmission,
    bank wire or other teleprocess or electronic instruction or trade
    information system acceptable to the Bank which the Bank believes in good
    faith to have been given by Authorized Persons or which are transmitted
    with proper testing or authentication pursuant to terms and conditions
    which the Bank may specify.  Unless otherwise expressly provided, all
    Instructions shall continue in full force and effect until canceled or
    superseded.

    Any Instructions delivered to the Bank by telephone shall promptly
    thereafter be confirmed in writing by an Authorized Person (which
    confirmation may bear the facsimile signature of such Person), but the
    Customer will hold the Bank harmless for the failure of an Authorized
    Person to send such confirmation in writing, the failure of such
    confirmation to conform to the telephone instructions received or the
    Bank's failure to produce such confirmation at any subsequent time.  The
    Bank may electronically record any Instructions given by telephone, and
    any other telephone discussions with respect to the Custody Account.  The
    Customer shall be responsible for safeguarding any testkeys,
    identification codes or other security devices which the Bank shall make
    available to the Customer or its Authorized Persons.

12. STANDARD OF CARE; LIABILITIES.

    (a)      The Bank shall be responsible for the performance of only such
             duties as are set forth in this Agreement or expressly contained
             in Instructions which are consistent with the provisions of this
             Agreement as follows:

             (i)   The Bank will use reasonable care with respect to its
                   obligations under this Agreement and the safekeeping of
                   Assets.  The Bank shall be liable to the Customer for any
                   loss which shall occur as the result of the failure of a
                   Subcustodian to exercise reasonable care with respect to the
                   safekeeping of such Assets to the same extent that the Bank
                   would be liable to the Customer if the Bank were holding
                   such Assets in New York.  In the event of any loss to the
                   Customer by reason of the failure of the Bank or its
                   Subcustodian to utilize reasonable care, the Bank shall be
                   liable to the Customer only to the extent of the Customer's
                   direct damages, to be determined based on the market value
                   of the property which is the subject of the loss at the date
                   of discovery of such loss and without reference to any

         In the event that SMC requests the Fund to indemnify or hold it
         harmless hereunder, SMC shall use its best efforts to inform the Fund
         of the relevant facts concerning the matter in question.  SMC shall
         use reasonable care to identify and promptly notify the Fund
         concerning any matter which presents, or appears likely to present, a
         claim for indemnification against the Fund.

         The Fund shall have the election of defending SMC against any claim
         which may be the subject of indemnification hereunder.  In the event
         the Fund so elects, it will so notify SMC and thereupon the Fund shall
         take over defenses of the claim, and (if so requested by the Fund, SMC
         shall incur no further legal or other claims related thereto for which
         it would be entitled to indemnity hereunder provided, however, that
         nothing herein contained shall prevent SMC from retaining, at its own
         expense, counsel to defend any claim.  Except with the Fund's prior
         consent, SMC shall in no event confess any claim or make any
         compromise in any matter in which the Fund will be asked to indemnify
         or hold SMC harmless hereunder.

                 Punitive Damages.  SMC shall not be liable to the Fund, or any
                 third party, for punitive, exemplary, indirect, special or
                 consequential damages (even if SMC has been advised of the
                 possibility of such damages) arising from its obligations and
                 the services provided under this agreement, including but not
                 limited to loss of profits,
<PAGE>   4

                 loss of use of the shareholder accounting system, cost of
                 capital and expenses of substitute facilities, programs or 
                 services.

                 Force Majeure.  Anything in this agreement to the contrary
                 notwithstanding, SMC shall not be liable for delays or errors
                 occurring by reason of circumstances beyond its control,
                 including but not limited to acts of civil or military
                 authority, national emergencies, work stoppages, fire, flood,
                 catastrophe, earthquake, acts of God, insurrection, war, riot,
                 failure of communication or interruption.

7.       Delegation of Duties

         SMC may, at its discretion, delegate, assign or subcontract any of the
         duties, responsibilities and services governed by this agreement, to
         its parent company, Security Benefit Group, Inc., whether or not by
         formal written agreement.  SMC shall, however, retain ultimate
         responsibility to the Fund, and shall implement such reasonable
         procedures as may be necessary, for assuring that any duties,
         responsibilities or services so assigned, subcontracted or delegated
         are performed in conformity with the terms and conditions of this
         agreement.

8.       Amendment

         This agreement and the schedules forming a part hereof may be amended
         at any time, without shareholder approval, by a writing signed by each
         of the parties hereto.  Any change in the Fund's registration
         statements or other documents of compliance or in the forms relating
         to any plan, program or service offered by its current prospectus
         which would require a change in SMC's obligations hereunder shall be
         subject to SMC's approval, which shall not be unreasonably withheld.

9.       Termination

         This agreement may be terminated by either party without cause upon
         120 days' written notice to the other, and at any time for cause in
         the event that such cause remains unremedied for more than 30 days
         after receipt by the other party of written specification of such
         cause.

         In the event Fund designates a successor to any of SMC's obligations
         hereunder, SMC shall, at the expense and pursuant to the direction of
         the Fund, transfer to such successor all relevant books, records and
         other data of Fund in the possession or under the control of SMC.

10.      Severability

         If any clause or provision of this agreement is determined to be
         illegal, invalid or unenforceable under present or future laws
         effective during the term hereof, then such
<PAGE>   5

         clause or provision shall be considered severed herefrom and the
         remainder of this agreement shall continue in full force and effect.

11.      Term

         This agreement initially shall become effective upon its approval by a
         majority vote of the Board of Directors of the Fund, including a
         majority vote of the Directors who are not "interested persons" of
         Fund or SMC, as defined in the Investment Company Act of 1940, and
         shall continue until terminated pursuant to its provisions.

12.      Applicable Law

         the laws of the State of Kansas.

      in Section 2(a)(4) of the 1940 Act, in the event of formal proceedings
      being instituted against the Sub-Administrator by the SEC or any state
      Securities Department or any other regulatory body that materially relate
      to or are likely to materially affect the Sub-Administrator's duties
      under this Agreement, in the event of the commencement of bankruptcy,

                                CANCELLATION FEE

The parties hereto agree that the Sub-Administrator shall be entitled to
$161,250, over a fifteen (15) month period, as the minimum compensation under
the terms of this Agreement.  Therefore, if the Administrator terminates this
Agreement before the expiration of such fifteen month period (except for
termination under any one of the automatic termination provisions set forth in
Section 11 of the Agreement), the Sub-Administrator shall be entitled to a
cancellation fee which equals the difference between the amount previously paid
by the Administrator under this Agreement (as of the effective date of the
termination) and the minimum compensation of $161,250.

                   AMENDMENT TO SUB-ADMINISTRATIVE AGREEMENT


WHEREAS, Security Management Company (hereafter "SMC" or the "Administrator")
and Lexington Management Corporation (hereafter "LMC" or the
"Sub-Administrator") are parties to a Sub-Administrative Agreement dated
September 10, 1993 (the "Agreement") under which LMC, as Sub-Administrator,
agrees to provide certain administrative services, as specified in section 2 of
the Agreement, to certain identified mutual funds or series of mutual funds for
which SMC serves as Administrator; and

WHEREAS, SMC desires to retain the services of LMC to provide the same
administrative services as outlined in the Agreement to certain other mutual
funds;

NOW THEREFORE, SMC and LMC hereby amend the Sub-Administrative Agreement dated
September 10, 1993, effective ______________, 1995, as follows:

Notwithstanding any other provision of the Agreement to the contrary, LMC
agrees to provide the services identified in section 2 of the Agreement to the
following mutual funds, or series thereof:  the Global Series (both Class A and
Class B shares) of Security Equity Fund, the Global Aggressive Bond Series
(both Class A and Class B shares) of Security Income Fund,  Series D and  K of
the SBL Fund and the International Discovery Series of the Parkstone Advantage
Fund (collectively referred to as the "Series").

Notwithstanding any other provision of the Agreement to the contrary, the
facilities and services outlined in section 2 of the Agreement shall be
provided separately, where appropriate, for Class A and Class B shares of the
Global Series of Security Equity Fund and for the Global Income Series of
Security Income Fund, including but not limited to items c, h, i, and j of
section 2.

Section 8 of the Agreement shall be deleted in its entirety and the following
section inserted in lieu thereof:

8.  Compensation.  For the services to be rendered to the Series and the
facilities furnished hereunder, the Administrator shall pay the
Sub-Administrator annual compensation which shall consist of an Annual Base Fee
of $9,000 per Series per contract year, plus the greater of (i) the Minimum
Fund Fee of $47,000 per Series per contract year or (ii) the Aggregate Asset
Fee below.  However, if the Sub-Administrator is instructed by the
Administrator to discontinue providing services to the International Discovery
Series of the Parkstone Advantage Fund, there will be a corresponding reduction
in the Annual Base Fee and the Minimum Fund Fee.  If such instruction relative
to the International Discovery Series is received by the Sub-Administrator
prior to the end of a contract year, the reduction in the Annual Base Fee and
the Minimum Fund Fee shall be prorated.

<S>                                                                         <C>
Less than $500 million                                                         .07%, plus
 
$500 million but less than $1 billion                                          .045%, plus

$1 billion or more                                                             .025%
</TABLE>

The Annual Base Fee for each Series shall be paid monthly at 1/12th of the
annual rate stated.  The greater of (i) or (ii) above will be paid monthly at
1/12th of the annual rate stated for the Minimum Fund Fee or at 1/12th of the
annual rate for the Aggregate Asset Fee based on annual average net assets, as
applicable.

A contract year shall be deemed to be that 12-month period starting from the
date of this Amendment.  If this Agreement shall be effective for only a
portion of a year, then the Sub-Administrator's annual compensation for said
year shall be prorated for such portion.  Payment of the Sub-Administrator's
compensation for the preceding month shall be made as promptly as possible
after the end of each month.

The compensation provided for in this Section 8 does not include out-of-pocket
expenses incurred by LMC on behalf of the Series.  Example's of out-of-pocket
expenses include but are not limited to disaster recovery, pricing services
(except pricing services already provided as part of LMC's in-house quote
system or as part of the DST software services) and overnight mailing services.
Out-of-pocket expenses will be billed by LMC on a monthly basis and will be
billed separately from service fees.  However, out-of-pocket expenses incurred
by LMC for converting Series D of SBL Fund to the DST system, will be borne by
LMC.

Section 11 of the Agreement (including Exhibit 1 to the Agreement) shall be
deleted in its entirety and the following section inserted in lieu thereof:

11.  Termination.  The term of this Agreement shall be two years and shall
begin on the date of this Amendment.  Thereafter, the Agreement shall continue
at the will of the parties and may be canceled without the payment of any
penalty upon ninety (90) days written notice to the other party.
Notwithstanding any of the foregoing, this Agreement shall automatically
terminate without the payment of any penalty (i) in the event of its assignment
as that term is defined in Section 2(a)(4) of the 1940 Act, (ii) in the event
of formal proceedings being instituted against the Sub-Administrator by the SEC
or any state Securities Department or any other regulatory body that materially
relate to or are likely to materially affect the Sub-Administrator's duties
under this Agreement, (iii) in the event of the commencement of bankruptcy,
liquidation or similar proceedings respecting the Sub-Administrator, or (iv) in
the event of a material breach in performing the duties specified under this
Agreement (such termination to be at the option of the non-breaching party).



IN WITNESS WHEREOF, the parties hereto have made this Amendment to the
Sub-Administrative Agreement this ___ day of _______________, 1995.

                                                    As amended November 26, 1990

                               DISTRIBUTION PLAN


        1.  The Plan.  This Distribution Plan (the "Plan") provides for the
financing by Security Income Fund (the "Fund") of activities which are, or may
be deemed to be, primarily intended to result in the sale of 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).

        2.  Covered Expenses.
        (a)  The Fund may make payments under this Plan to the Distributor in
connection with 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 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 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 as
distribution or service fees who have executed a Dealer's Distribution
Agreement with the Distributor; and
                (vi)  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.  
(Amended 11-26-90.)
        (b)  Any payments to the Distributor for distribution-related
activities shall be made pursuant to the agreement between the Fund and the
Distributor contemplated by Section 3 of this Plan.  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 8
of this Plan.  However, this Plan shall not obligate the Fund or any other
party to enter into such agreement.
        (c)  No payments received by the Distributor pursuant to this section
are to be used to compensate the Distributor for its overhead costs, or to
reimburse the Distributor for interest, financing or other carrying costs which
it may incur in financing distribution-related activities for the Fund.
(Amended 10-17-86.)
<PAGE>   2

        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 provisions to
the following effect.
         (i)  For the fiscal year of the Fund during which this Plan becomes
effective and for each subsequent fiscal year of the Fund during which this
Plan remains in effect, the Distributor shall submit to the Fund a budget
setting forth in reasonable detail the distribution-related activities to which
the Distributor proposes to apply payments made by the Fund hereunder.
        (ii)  Before any payment is made to the Distributor in respect of any
fiscal year, the budget relating thereto shall be approved by vote of the
Fund's Directors, including the affirmative vote of a majority of the
Independent Directors.
       (iii)  The Distributor shall furnish the Fund with quarterly reports
of its expenditures pursuant to each budget so approved, together with receipts
or other appropriate written evidence of the amounts expended, and such other
information relating to such budget or 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.  Distribution Agreement.  The Dealer's Distribution Agreement (the
"Agreement") contemplated by paragraph 2(v) above shall permit payments 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 a majority of the directors who are not
interested persons of the Fund (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) as required by the
Rule.  The Distributor may pay to the other party to any Agreement a quarterly
fee for distribution and marketing services provided by such other party.  Such
quarterly fee shall be payable in arrears in an amount equal to such percentage
( not in excess of .000685% per day or .25 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 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 quarterly fee.  (Amended 10-17-86.)

        5.  Limitations on Covered Expenses.  The basic limitation on the
expenses incurred by the Fund under Section 2 of this Plan 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 to the
Distributor pursuant to this Plan shall be prorated and charged to each Series
of the Fund in proportion to the relative net assets of each Series.  (Amended
10-17-86.)

        6.  Disinterested Directors.  While this Plan is in effect, the
selection and nomination of Disinterested Directors of the Fund shall be
committed to the discretion of the Disinterested Directors.  Nothing herein
shall prevent the involvement of others in such selection and
<PAGE>   3

nomination if the final decision on any such selection and nomination is
approved by a majority of the Disinterested Directors.  (Amended 10-17-86.)

        7.  Reports.  While this Plan is in effect each person (other than the
Distributor) entering an agreement with the Fund as contemplated by Section
2(c) of this Plan shall provide to the Fund, at such intervals no less often
than quarterly as it may require written reports setting forth in reasonable
detail: 
        
         (i)  Information concerning the expenses incurred and payments made by
such person for the distribution-related activities during the last preceding
fiscal quarter or, if the Fund requires reports more frequently than quarterly,
during such shorter interval most recently ended, and 

        (ii)  Such other information as may be called for by the agreement 
between the Fund and such person.

        8.  Effectiveness, Continuation, Termination and Amendment.  This Plan
and each agreement relating to the implementation of this Plan shall go into
effect when approved.

         (i)  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, and
        (ii)  In the case of this Plan, also b a vote of holders of at least a
majority of the outstanding voting securities of each Series, however, in the
event that this plan is approved by such vote of the outstanding voting
securities of one or more Series but not of one or more others, this Plan shall
be in effect with respect to the former such Series but not with respect to the
latter such Series; and
       (iii)  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.  (Amended 10-17-86.)

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 days' written
notice 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 Funds.  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, 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 under the
Plan, it shall also require approval by a vote of holders of at least a
majority of the outstanding voting securities of the Fund.  As applied to the
Fund the phrase "majority of the outstanding voting securities" shall have the
meaning specified in Section 2(a) of the 1940 Act.

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.

                               DISTRIBUTION PLAN

1.    The Plan.  This Distribution Plan (the "Plan"), provides for the
      financing by Security Income Fund (the "Fund") of activities which are,
      or may be deemed to be, primarily intended to result in the sale of class
      B 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 B 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 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 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 (a
                          "Service Fee");
<PAGE>   2

             (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 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 any
      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 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 percent (1.00%) 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 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 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 under the Plan,
      it shall also require approval by a vote of holders of at least a
      majority of the outstanding voting securities of the Fund.  As applied to
      the Fund the phrase "majority of the outstanding voting securities" shall
      have the meaning specified in Section 2(a) of the 1940 Act.

      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, any
      such Agreement or any such report, as the case may be, the first two
      years in an easily accessible place.
