                              December 31, 1999


                 This Statement of Additional Information expands upon and
                 supplements the information contained in the current Prospectus
                 for the Service Shares (the "Shares") of Money Market
                 Portfolio. The Portfolio is each a separate series of Janus
                 Aspen Series, a Delaware trust.


                 The Service Shares of the Portfolio may be purchased only by
                 the separate accounts of insurance companies for the purpose of
                 funding variable life insurance policies and variable annuity
                 contracts (collectively, "variable insurance contracts") and by
                 certain qualified retirement plans.

                 This SAI is not a Prospectus and should be read in conjunction
                 with the Prospectus dated December 31, 1999, which is
                 incorporated by reference into this SAI and may be obtained
                 from your insurance company or plan sponsor. This SAI contains
                 additional and more detailed information about the Portfolio's
                 operations and activities than the Prospectus. The Annual
                 Report, which contains important financial information about
                 the Portfolio, is incorporated by reference into this SAI and
                 is also available, without charge, from your insurance company
                 or plan sponsor.

Investment restrictions and investment strategies

INVESTMENT RESTRICTIONS

          The Portfolio has adopted certain fundamental investment restrictions
          that cannot be changed without shareholder approval. Shareholder
          approval means approval by the lesser of (i) more than 50% of the
          outstanding voting securities of the Trust (or the Portfolio or class
          of shares if a matter affects just the Portfolio or class of shares),
          or (ii) 67% or more of the voting securities present at a meeting if
          the holders of more than 50% of the outstanding voting securities of
          the Trust (or the Portfolio or class of shares) are present or
          represented by proxy.

          As used in the restrictions set forth below and as used elsewhere in
          this SAI, the term "U.S. Government Securities" shall have the meaning
          set forth in the Investment Company Act of 1940, as amended (the "1940
          Act"). The 1940 Act defines U.S. Government Securities as securities
          issued or guaranteed by the United States government, its agencies or
          instrumentalities. U.S. Government Securities may also include
          repurchase agreements collateralized and municipal securities escrowed
          with or refunded with escrowed U.S. government securities.

          The Portfolio has adopted the following fundamental policies:

          (1) With respect to 75% of its assets, the Portfolio may not purchase
          a security other than a U.S. Government Security, if, as a result,
          more than 5% of its total assets would be invested in the securities
          of a single issuer or the Portfolio would own more than 10% of the
          outstanding voting securities of any single issuer. (As noted in the
          Prospectus, the Portfolio is currently subject to the greater
          diversification standards of Rule 2a-7, which are not fundamental.)

          (2) The Portfolio may not purchase securities if 25% or more of the
          value of its total assets would be invested in the securities of
          issuers conducting their principal business activities in the same
          industry; provided that: (i) there is no limit on investments in U.S.
          Government Securities or in obligations of domestic commercial banks
          (including U.S. branches of foreign banks subject to regulations under
          U.S. laws applicable to domestic banks and, to the extent that its
          parent is unconditionally liable for the obligation, foreign branches
          of U.S. banks); (ii) this limitation shall not apply to the
          Portfolio's investments in municipal securities; (iii) there is no
          limit on investment in issuers domiciled in a single country; (iv)
          financial service companies are classified according to the end users
          of their services (for example, automobile finance, bank finance and
          diversified finance are each considered to be a separate industry);
          and (v) utility companies are classified according to their services
          (for example, gas, gas transmission, electric, and telephone are each
          considered to be a separate industry).

          (3) The Portfolio may not act as an underwriter of securities issued
          by others, except to the extent that it may be deemed an underwriter
          in connection with the disposition of its portfolio securities.

          (4) The Portfolio may not lend any security or make any other loan if,
          as a result, more than 25% of its total assets would be lent to other
          parties (but this limitation does not apply to purchases of commercial
          paper, debt securities or repurchase agreements).

          (5) The Portfolio may not purchase or sell real estate or any interest
          therein, except that the Portfolio may invest in debt obligations
          secured by real estate or interests therein or securities issued by
          companies that invest in real estate or interests therein.

          (6) The Portfolio may borrow money for temporary or emergency purposes
          (not for leveraging) in an amount not exceeding 25% of the value of
          its total assets (including the amount borrowed) less liabilities
          (other than borrowings). If borrowings exceed 25% of the value of the
          Portfolio's total assets by reason of a decline in net assets, it will
          reduce its borrowings within three business days to the extent
          necessary to comply with the 25% limitation. Reverse repurchase
          agreements or the segregation of assets in connection with such
          agreements shall not be considered borrowing for the purposes of this
          limit.

<PAGE>

          (7) The Portfolio may, notwithstanding any other investment policy or
          restriction (whether or not fundamental), invest all of its assets in
          the securities of a single open-end management investment company with
          substantially the same fundamental investment objectives, policies and
          restrictions as the Portfolio.

          Investment restriction (1) is intended to reflect the requirements
          under Section 5(b)(1) of the 1940 Act for a diversified fund. Rule
          2a-7 provides that money market funds that comply with the
          diversification limits of Rule 2a-7 are deemed to comply with the
          diversification limits of Section 5(b)(1). Thus, the Portfolio
          interprets restriction (1) in accordance with Rule 2a-7. Accordingly,
          if securities are subject to a guarantee provided by a non-controlled
          person, the Rule 2a-7 diversification tests apply to the guarantor,
          and the diversification test in restriction (1) does not apply to the
          issuer.

          The Portfolio has adopted the following nonfundamental investment
          restrictions that may be changed by the Trustees without shareholder
          approval:

          (1) The Portfolio may not invest in securities or enter into
          repurchase agreements with respect to any securities if, as a result,
          more than 10% of its net assets would be invested in repurchase
          agreements not entitling the holder to payment of principal within
          seven days and in other securities that are not readily marketable
          ("illiquid securities"). The Trustees, or the Portfolio's investment
          adviser acting pursuant to authority delegated by the Trustees, may
          determine that a readily available market exists for certain
          securities such as securities eligible for resale pursuant to Rule
          144A under the Securities Act of 1933, or any successor to such rule,
          Section 4(2) commercial paper and municipal lease obligations.
          Accordingly, such securities may not be subject to the foregoing
          limitation.

          (2) The Portfolio may not purchase securities on margin, or make short
          sales of securities, except for short sales against the box and the
          use of short-term credit necessary for the clearance of purchases and
          sales of portfolio securities.

          (3) The Portfolio may not pledge, mortgage, hypothecate or encumber
          any of its assets except to secure permitted borrowings or in
          connection with permitted short sales.

          (4) The Portfolio may not invest in companies for the purpose of
          exercising control of management.

          Under the terms of an exemptive order received from the Securities and
          Exchange Commission ("SEC"), the Portfolio may borrow money from or
          lend money to other funds that permit such transactions and for which
          Janus Capital serves as investment adviser. All such borrowing and
          lending will be subject to the above limits. The Portfolio will borrow
          money through the program only when the costs are equal to or lower
          than the cost of bank loans. Interfund loans and borrowings normally
          extend overnight, but can have a maximum duration of seven days. The
          Portfolio will lend through the program only when the returns are
          higher than those available from other short-term instruments (such as
          repurchase agreements). The Portfolio may have to borrow from a bank
          at a higher interest rate if an interfund loan is called or not
          renewed. Any delay in repayment to a lending Portfolio could result in
          a lost investment opportunity or additional borrowing costs.

          For purposes of the Portfolio's policies on investing in particular
          industries, the Portfolio will rely primarily on industry or industry
          group classifications as published by Bloomberg L.P. To the extent
          that Bloomberg L.P. industry classifications are so broad that the
          primary economic characteristics in a single industry are materially
          different, the Portfolio may further classify issuers in accordance
          with industry classifications as published by the SEC.

                                                                               3

INVESTMENT STRATEGIES

          The Portfolio may invest only in "eligible securities" as defined in
          Rule 2a-7 adopted under the 1940 Act. Generally, an eligible security
          is a security that (i) is denominated in U.S. dollars and has a
          remaining maturity of 397 days or less (as calculated pursuant to Rule
          2a-7); (ii) is rated, or is issued by an issuer with short-term debt
          outstanding that is rated, in one of the two highest rating categories
          by any two nationally recognized statistical rating organizations
          ("NRSROs") or, if only one NRSRO has issued a rating, by that NRSRO
          (the "Requisite NRSROs") or is unrated and of comparable quality to a
          rated security, as determined by Janus Capital; and (iii) has been
          determined by Janus Capital to present minimal credit risks pursuant
          to procedures approved by the Trustees. In addition, the Portfolio
          will maintain a dollar-weighted average portfolio maturity of 90 days
          or less. A description of the ratings of some NRSROs appears in
          Appendix A.

          Under Rule 2a-7, the Portfolio may not invest more than five percent
          of its total assets in the securities of any one issuer other than
          U.S. Government Securities, provided that in certain cases it may
          invest more than 5% of its assets in a single issuer for a period of
          up to three business days. Investment in demand features, guarantees
          and other types of instruments or features are subject to the
          diversification limits under Rule 2a-7.

          Pursuant to Rule 2a-7, the Portfolio will invest at least 95% of its
          total assets in "first-tier" securities. First-tier securities are
          eligible securities that are rated, or are issued by an issuer with
          short-term debt outstanding that is rated, in the highest rating
          category by the Requisite NRSROs or are unrated and of comparable
          quality to a rated security. In addition, the Portfolio may invest in
          "second-tier" securities which are eligible securities that are not
          first-tier securities. However, the Portfolio may not invest in a
          second-tier security if immediately after the acquisition thereof it
          would have invested more than (i) the greater of one percent of its
          total assets or one million dollars in second-tier securities issued
          by that issuer, or (ii) five percent of its total assets in
          second-tier securities.

          The following discussion of types of securities in which the Portfolio
          may invest supplements and should be read in conjunction with the
          Prospectus.

Participation Interests

          The Portfolio may purchase participation interests in loans or
          securities in which it may invest directly. Participation interests
          are generally sponsored or issued by banks or other financial
          institutions. A participation interest gives the Portfolio an
          undivided interest in the underlying loans or securities in the
          proportion that the Portfolio's interest bears to the total principal
          amount of the underlying loans or securities. Participation interests,
          which may have fixed, floating or variable rates, may carry a demand
          feature backed by a letter of credit or guarantee of a bank or
          institution permitting the holder to tender them back to the bank or
          other institution. For certain participation interests, the Portfolio
          will have the right to demand payment, on not more than seven days'
          notice, for all or a part of the Portfolio's participation interest.
          The Portfolio intends to exercise any demand rights it may have upon
          default under the terms of the loan or security, to provide liquidity
          or to maintain or improve the quality of the Portfolio's investment
          portfolio. The Portfolio will only purchase participation interests
          that Janus Capital determines present minimal credit risks.

Variable and Floating Rate Notes

          The Portfolio also may purchase variable and floating rate demand
          notes of corporations, which are unsecured obligations redeemable upon
          not more than 30 days' notice. These obligations include master demand
          notes that permit investment of fluctuating amounts at varying rates
          of interest pursuant to direct

 4
<PAGE>

          arrangements with the issuer of the instrument. The issuer of these
          obligations often has the right, after a given period, to prepay the
          outstanding principal amount of the obligations upon a specified
          number of days' notice. These obligations generally are not traded,
          nor generally is there an established secondary market for these
          obligations. To the extent a demand note does not have a seven day or
          shorter demand feature and there is no readily available market for
          the obligation, it is treated as an illiquid investment.

          Securities with ultimate maturities of greater than 397 days may be
          purchased only pursuant to Rule 2a-7. Under that Rule, only those
          long-term instruments that have demand features which comply with
          certain requirements and certain variable rate U.S. Government
          Securities may be purchased. The rate of interest on securities
          purchased by the Portfolio may be tied to short-term Treasury or other
          government securities or indices on securities that are permissible
          investments of the Portfolio, as well as other money market rates of
          interest. The Portfolio will not purchase securities whose values are
          tied to interest rates or indices that are not appropriate for the
          duration and volatility standards of a money market fund.

Mortgage- and Asset-Backed Securities

          The Portfolio may invest in mortgage-backed securities, which
          represent an interest in a pool of mortgages made by lenders such as
          commercial banks, savings and loan institutions, mortgage bankers,
          mortgage brokers and savings banks. Mortgage-backed securities may be
          issued by governmental or government-related entities or by
          non-governmental entities such as banks, savings and loan
          institutions, private mortgage insurance companies, mortgage bankers
          and other secondary market issuers.

          Interests in pools of mortgage-backed securities differ from other
          forms of debt securities which normally provide for periodic payment
          of interest in fixed amounts with principal payments at maturity or
          specified call dates. In contrast, mortgage-backed securities provide
          periodic payments which consist of interest and, in most cases,
          principal. In effect, these payments are a "pass-through" of the
          periodic payments and optional prepayments made by the individual
          borrowers on their mortgage loans, net of any fees paid to the issuer
          or guarantor of such securities. Additional payments to holders of
          mortgage-backed securities are caused by prepayments resulting from
          the sale of the underlying residential property, refinancing or
          foreclosure, net of fees or costs which may be incurred.

          As prepayment rates of individual pools of mortgage loans vary widely,
          it is not possible to predict accurately the average life of a
          particular security. Although mortgage-backed securities are issued
          with stated maturities of up to forty years, unscheduled or early
          payments of principal and interest on the underlying mortgages may
          shorten considerably the effective maturities. Mortgage-backed
          securities may have varying assumptions for average life. The volume
          of prepayments of principal on a pool of mortgages underlying a
          particular security will influence the yield of that security, and the
          principal returned to the Portfolio may be reinvested in instruments
          whose yield may be higher or lower than that which might have been
          obtained had the prepayments not occurred. When interest rates are
          declining, prepayments usually increase, with the result that
          reinvestment of principal prepayments will be at a lower rate than the
          rate applicable to the original mortgage-backed security.

          The Portfolio may invest in mortgage-backed securities that are issued
          by agencies or instrumentalities of the U.S. government. The
          Government National Mortgage Association ("GNMA") is the principal
          federal government guarantor of mortgage-backed securities. GNMA is a
          wholly-owned U.S. government corporation within the Department of
          Housing and Urban Development. GNMA Certificates are debt securities
          which represent an interest in one mortgage or a pool of mortgages
          which are insured by the Federal Housing Administration or the Farmers
          Home Administration or are guaranteed by the Veterans Administration.
          The Portfolio may also invest in pools of conventional mortgages which
          are issued or

                                                                               5
<PAGE>

          guaranteed by agencies of the U.S. government. GNMA pass-through
          securities are considered to be riskless with respect to default in
          that (i) the underlying mortgage loan portfolio is comprised entirely
          of government-backed loans and (ii) the timely payment of both
          principal and interest on the securities is guaranteed by the full
          faith and credit of the U.S. government, regardless of whether or not
          payments have been made on the underlying mortgages. GNMA pass-through
          securities are, however, subject to the same market risk as comparable
          debt securities. Therefore, the market value of the Portfolio's GNMA
          securities can be expected to fluctuate in response to changes in
          prevailing interest rate levels.

          Residential mortgage loans are pooled also by the Federal Home Loan
          Mortgage Corporation ("FHLMC"). FHLMC is a privately managed, publicly
          chartered agency created by Congress in 1970 for the purpose of
          increasing the availability of mortgage credit for residential
          housing. FHLMC issues participation certificates ("PCs") which
          represent interests in mortgages from FHLMC's national portfolio. The
          mortgage loans in FHLMC's portfolio are not U.S. government backed;
          rather, the loans are either uninsured with loan-to-value ratios of
          80% or less, or privately insured if the loan-to-value ratio exceeds
          80%. FHLMC guarantees the timely payment of interest and ultimate
          collection of principal on FHLMC PCs; the U.S. government does not
          guarantee any aspect of FHLMC PCs.

          The Federal National Mortgage Association ("FNMA") is a
          government-sponsored corporation owned entirely by private
          shareholders. It is subject to general regulation by the Secretary of
          Housing and Urban Development. FNMA purchases residential mortgages
          from a list of approved seller/servicers which include savings and
          loan associations, savings banks, commercial banks, credit unions and
          mortgage bankers. FNMA guarantees the timely payment of principal and
          interest on the pass-through securities issued by FNMA; the U.S.
          government does not guarantee any aspect of the FNMA pass-through
          securities.

          The Portfolio may also invest in privately-issued mortgage-backed
          securities to the extent permitted by their investment restrictions.
          Mortgage-backed securities offered by private issuers include
          pass-through securities comprised of pools of conventional residential
          mortgage loans; mortgage-backed bonds which are considered to be debt
          obligations of the institution issuing the bonds and which are
          collateralized by mortgage loans; and collateralized mortgage
          obligations ("CMOs") which are collateralized by mortgage-backed
          securities issued by GNMA, FHLMC or FNMA or by pools of conventional
          mortgages.

          Asset-backed securities represent direct or indirect participation in,
          or are secured by and payable from, assets other than mortgage-backed
          assets such as motor vehicle installment sales contracts, installment
          loan contracts, leases of various types of real and personal property
          and receivables from revolving credit agreements (credit cards).
          Asset-backed securities have yield characteristics similar to those of
          mortgage-backed securities and, accordingly, are subject to many of
          the same risks.

Securities Lending

          The Portfolio may lend securities to qualified parties (typically
          brokers or other financial institutions) who need to borrow securities
          in order to complete certain transactions such as covering short
          sales, avoiding failures to deliver securities or completing arbitrage
          activities. The Portfolio may seek to earn additional income through
          securities lending. Since there is the risk of delay in recovering a
          loaned security or the risk of loss in collateral rights if the
          borrower fails financially, securities lending will only be made to
          parties that Janus Capital deems creditworthy and in good standing. In
          addition, such loans will only be made if Janus Capital believes the
          benefit from granting such loans justifies the risk. The Portfolio
          will not have the right to vote on securities while they are being
          lent, but it will call a loan in anticipation of any important vote.
          All loans will be continuously secured by collateral which consists of
          cash, U.S. government securities, letters of credit and such other
          collateral permitted by the Securities and Exchange Commission and
          policies approved by the Trustees. Cash collateral may be invested in
          money

          market funds advised by Janus Capital to the extent consistent with
          exemptive relief obtained from the SEC.

Reverse Repurchase Agreements

          Reverse repurchase agreements are transactions in which the Portfolio
          sells a security and simultaneously commits to repurchase that
          security from the buyer at an agreed upon price on an agreed upon
          future date. The resale price in a reverse repurchase agreement
          reflects a market rate of interest that is not related to the coupon
          rate or maturity of the sold security. For certain demand agreements,
          there is no agreed upon repurchase date and interest payments are
          calculated daily, often based upon the prevailing overnight repurchase
          rate. The Portfolio will use the proceeds of reverse repurchase
          agreements only to satisfy unusually heavy redemption requests or for
          other temporary or emergency purposes without the necessity of selling
          portfolio securities.

          Generally, a reverse repurchase agreement enables the Portfolio to
          recover for the term of the reverse repurchase agreement all or most
          of the cash invested in the portfolio securities sold and to keep the
          interest income associated with those portfolio securities. Such
          transactions are only advantageous if the interest cost to the
          Portfolio of the reverse repurchase transaction is less than the cost
          of obtaining the cash otherwise. In addition, interest costs on the
          money received in a reverse repurchase agreement may exceed the return
          received on the investments made by the Portfolio with those monies.

When Issued and Delayed Delivery Securities

          The Portfolio may purchase securities on a when-issued or delayed
          delivery basis. The Portfolio will enter into such transactions only
          when it has the intention of actually acquiring the securities. To
          facilitate such acquisitions, the Portfolio's custodian will segregate
          cash or high quality liquid assets in an amount at least equal to such
          commitments. On delivery dates for such transactions, the Portfolio
          will meet its obligations from maturities, sales of the segregated
          securities or from other available sources of cash. If it chooses to
          dispose of the right to acquire a when-issued security prior to its
          acquisition, the Portfolio could, as with the disposition of any other
          portfolio obligation, incur a gain or loss due to market fluctuation.
          At the time it makes the commitment to purchase securities on a
          when-issued or delayed delivery basis, the Portfolio will record the
          transaction as a purchase and thereafter reflect the value of such
          securities in determining its net asset value.

Investment Company Securities

          From time to time, the Portfolio may invest in securities of other
          investment companies. The Portfolio is subject to the provisions of
          Section 12(d)(1) of the 1940 Act. The Portfolio may invest in
          securities of money market funds managed by Janus Capital in excess of
          the limitations of Section 12(d)(1) under the terms of an SEC
          exemptive order obtained by Janus Capital and the Janus Funds.

Debt Obligations

          Money Market Portfolio may invest in debt obligations of domestic
          issuers. In general, sales of these securities may not be made absent
          registration under the Securities Act of 1933 or the availability of
          an appropriate exemption. Pursuant to Section 4(2) of the 1933 Act or
          Rule 144A adopted under the 1933 Act, however, some of these
          securities are eligible for resale to institutional investors, and
          accordingly, Janus Capital may determine that a liquid market exists
          for such a security pursuant to guidelines adopted by the Trustees.

                                                                               7

Obligations of Financial Institutions

          The Portfolio may invest in obligations of financial institutions.
          Examples of obligations in which the Portfolio may invest include
          negotiable certificates of deposit, bankers' acceptances, time
          deposits and other obligations of U.S. banks (including savings and
          loan associations) having total assets in excess of one billion
          dollars and U.S. branches of foreign banks having total assets in
          excess of ten billion dollars. The Portfolio may also invest in
          Eurodollar and Yankee bank obligations as discussed below and other
          U.S. dollar-denominated obligations of foreign banks having total
          assets in excess of ten billion dollars that Janus Capital believes
          are of an investment quality comparable to obligations of U.S. banks
          in which the Portfolio may invest.

          Certificates of deposit represent an institution's obligation to repay
          funds deposited with it that earn a specified interest rate over a
          given period. Bankers' acceptances are negotiable obligations of a
          bank to pay a draft which has been drawn by a customer and are usually
          backed by goods in international trade. Time deposits are
          non-negotiable deposits with a banking institution that earn a
          specified interest rate over a given period. Fixed time deposits,
          which are payable at a stated maturity date and bear a fixed rate of
          interest, generally may be withdrawn on demand by the Portfolio but
          may be subject to early withdrawal penalties and that could reduce the
          Portfolio's yield. Unless there is a readily available market for
          them, time deposits that are subject to early withdrawal penalties and
          that mature in more than seven days will be treated as illiquid
          securities.

          Eurodollar bank obligations are dollar-denominated certificates of
          deposit or time deposits issued outside the U.S. capital markets by
          foreign branches of U.S. banks and by foreign banks. Yankee bank
          obligations are dollar-denominated obligations issued in the U.S.
          capital markets by foreign banks.

          Foreign, Eurodollar (and to a limited extent, Yankee) bank obligations
          are subject to certain sovereign risks. One such risk is the
          possibility that a foreign government might prevent dollar-denominated
          funds from flowing across its borders. Other risks include: adverse
          political and economic developments in a foreign country; the extent
          and quality of government regulation of financial markets and
          institutions; the imposition of foreign withholding taxes; and
          exploration or nationalization of foreign issuers.

U.S. Government Securities

          Money Market Portfolio may invest in U.S. Government Securities. U.S.
          Government Securities shall have the meaning set forth in the 1940
          Act. The 1940 Act defines U.S. Government Securities to include
          securities issued or guaranteed by the U.S. Government, its agencies
          and instrumentalities. U.S. Government Securities may also include
          repurchase agreements collateralized by and municipal securities
          escrowed with or refunded with U.S. government securities. U.S.
          Government Securities in which the Portfolio may invest include U.S.
          Treasury securities and obligations issued or guaranteed by U.S.
          government agencies and instrumentalities that are backed by the full
          faith and credit of the U.S. government, such as those guaranteed by
          the Small Business Administration or issued by the Government National
          Mortgage Association. In addition, U.S. Government Securities in which
          the Portfolio may invest include securities supported primarily or
          solely by the creditworthiness of the issuer, such as securities of
          the Federal National Mortgage Association, the Federal Home Loan
          Mortgage Corporation and the Tennessee Valley Authority. There is no
          guarantee that the U.S. government will support securities not backed
          by its full faith and credit. Accordingly, although these securities
          have historically involved little risk of loss of principal if held to
          maturity, they may involve more risk than securities backed by the
          full faith and credit of the U.S. government.

Municipal Leases

          The Portfolio may invest in municipal leases. Municipal leases
          frequently have special risks not normally associated with general
          obligation or revenue bonds. Municipal leases are municipal securities
          which may take the form of a lease or an installment purchase or
          conditional sales contract. Municipal leases are issued by state and
          local governments and authorities to acquire a wide variety of
          equipment and facilities. Leases and installment purchase or
          conditional sale contracts (which normally provide for title to the
          leased asset to pass eventually to the government issuer) have evolved
          as a means for governmental issuers to acquire property and equipment
          without meeting the constitutional and statutory requirements for the
          issuance of debt. The debt-issuance limitations of many state
          constitutions and statutes are deemed to be inapplicable because of
          the inclusion in many leases or contracts of "non-appropriation"
          clauses that provide that the governmental issuer has no obligation to
          make future payments under the lease or contract unless money is
          appropriated for such purpose by the appropriate legislative body on a
          yearly or other periodic basis. The Portfolio will only purchase
          municipal leases subject to a non-appropriation clause when the
          payment of principal and accrued interest is backed by an
          unconditional irrevocable letter of credit, or guarantee of a bank or
          other entity that meets the criteria described in the Prospectus under
          "Taxable Investments."

          In evaluating municipal lease obligations, Janus Capital will consider
          such factors as it deems appropriate, including: (a) whether the lease
          can be canceled; (b) the ability of the lease obligee to direct the
          sale of the underlying assets; (c) the general creditworthiness of the
          lease obligor; (d) the likelihood that the municipality will
          discontinue appropriating funding for the leased property in the event
          such property is no longer considered essential by the municipality;
          (e) the legal recourse of the lease obligee in the event of such a
          failure to appropriate funding; (f) whether the security is backed by
          a credit enhancement such as insurance; and (g) any limitations which
          are imposed on the lease obligor's ability to utilize substitute
          property or services other than those covered by the lease obligation.
          If a lease is backed by an unconditional letter of credit or other
          unconditional credit enhancement, then Janus Capital may determine
          that a lease is an eligible security solely on the basis of its
          evaluation of the credit enhancement.

          Municipal leases, like other municipal debt obligations, are subject
          to the risk of non-payment. The ability of issuers of municipal leases
          to make timely lease payments may be adversely impacted in general
          economic downturns and as relative governmental cost burdens are
          allocated and reallocated among federal, state and local governmental
          units. Such non-payment would result in a reduction of income to the
          Portfolio, and could result in a reduction in the value of the
          municipal lease experiencing non-payment and a potential decrease in
          the net asset value of the Portfolio.

                                                                               9

Performance data

          The Portfolio may provide current annualized and effective annualized
          yield quotations of the Shares based on the Shares' daily dividends.
          These quotations may from time to time be used in advertisements,
          shareholder reports or other communications to shareholders. All
          performance information supplied by the Portfolio in advertising is
          historical and is not intended to indicate future returns.

          The Service Shares commenced operations on January 1, 2000. The
          returns shown for the Service Shares of the Money Market Portfolio
          reflect the historical performance of a different class of shares (the
          Institutional Shares) prior to January 1, 2000. The historical
          performance of the Institutional Shares has been restated for purposes
          of the Service Shares performance based on the Service Shares
          estimated fees and expenses (ignoring any fee and expense limitations)
          except where that restatement results in higher performance than the
          actual historical performance of the Institutional Shares.

          In performance advertising, the Portfolio may compare any of its
          performance information with data published by independent evaluators
          such as Morningstar, Inc., Lipper Analytical Services, Inc., or
          CDC/Wiesenberger, Donoghue's Money Fund Report or other companies
          which track the investment performance of investment companies ("Fund
          Tracking Companies"). The Portfolio may also compare its performance
          information with the performance of recognized stock, bond and other
          indices, including but not limited to the Municipal Bond Buyers
          Indices, the Salomon Brothers Bond Index, the Lehman Brothers Bond
          Index, the Standard & Poor's 500 Composite Stock Price Index, the Dow
          Jones Industrial Average, U.S. Treasury bonds, bills or notes and
          changes in the Consumer Price Index as published by the U.S.
          Department of Commerce. The Portfolio may refer to general market
          performance over past time periods such as those published by Ibbotson
          Associates (for instance, its "Stocks, Bonds, Bills and Inflation
          Yearbook"). The Portfolio may also refer in such materials to mutual
          fund performance rankings and other data published by Fund Tracking
          Companies. Performance advertising may also refer to discussions of
          the Portfolio and comparative mutual fund data and ratings reported in
          independent periodicals, such as newspapers and financial magazines.

          Any current yield quotation of the Portfolio's Shares which is used in
          such a manner as to be subject to the provisions of Rule 482(d) under
          the Securities Act of 1933, as amended, shall consist of an annualized
          historical yield, carried at least to the nearest hundredth of one
          percent, based on a specific seven calendar day period. The current
          yield of the Portfolio's Shares shall be calculated by (a) determining
          the net change during a seven calendar day period in the value of a
          hypothetical account having a balance of one share at the beginning of
          the period, (b) dividing the net change by the value of the account at
          the beginning of the period to obtain a base period return, and (c)
          multiplying the quotient by 365/7 (i.e., annualizing). For this
          purpose, the net change in account value will reflect the value of
          additional shares purchased with dividends declared on the original
          share and dividends declared on both the original share and any such
          additional shares, but will not reflect any realized gains or losses
          from the sale of securities or any unrealized appreciation or
          depreciation on portfolio securities. In addition, the Portfolio may
          advertise effective yield quotations. Effective yield quotations are
          calculated by adding 1 to the base period return, raising the sum to a
          power equal to 365/7, and subtracting 1 from the result (i.e.,
          compounding).

          Income calculated for the purpose of determining the yield of the
          Portfolio's Shares differs from income as determined for other
          accounting purposes. Because of the different accounting methods used,
          and because of the compounding assumed in yield calculations, the
          yield quoted for the Portfolio's Shares may differ from the rate of
          distribution the Shares paid over the same period or the rate of
          income reported in the Portfolio's financial statements.

<PAGE>

          Although published yield information is useful to investors in
          reviewing the performance of the Portfolio's Shares, investors should
          be aware that the yield fluctuates from day to day and that the
          Share's yield for any given period is not an indication or
          representation by the Portfolio of future yields or rates of return on
          the Portfolio's Shares. The Shares' yield is not fixed or guaranteed,
          and an investment in the Portfolio is not insured. Accordingly, the
          Shares' yield information may not necessarily be used to compare
          Portfolio Shares with investment alternatives which, like money market
          instruments or bank accounts, may provide a fixed rate of interest. In
          addition, because investments in the Portfolio are not insured or
          guaranteed, the yield information may not necessarily be used to
          compare the Portfolio with investment alternatives which are insured
          or guaranteed.

                                                                              11

Determination of net asset value

          Pursuant to the rules of the SEC, the Trustees have established
          procedures to stabilize the Portfolio's net asset value at $1.00 per
          Share. These procedures include a review of the extent of any
          deviation of net asset value per Share as a result of fluctuating
          interest rates, based on available market rates, from the Portfolio's
          $1.00 amortized cost price per Share. Should that deviation exceed
          1/2 of 1%, the Trustees will consider whether any action should be
          initiated to eliminate or reduce material dilution or other unfair
          results to shareholders. Such action may include redemption of shares
          in kind, selling portfolio securities prior to maturity, reducing or
          withholding dividends and utilizing a net asset value per share as
          determined by using available market quotations. The Portfolio i) will
          maintain a dollar-weighted average portfolio maturity of 90 days or
          less; ii) will not purchase any instrument with a remaining maturity
          greater than 397 days or subject to a repurchase agreement having a
          duration of greater than 397 days; iii) will limit portfolio
          investments, including repurchase agreements, to those U.S.
          dollar-denominated instruments that Janus Capital has determined
          present minimal credit risks pursuant to procedures established by the
          Trustees; and iv) will comply with certain reporting and recordkeeping
          procedures. The Trust has also established procedures to ensure that
          portfolio securities meet the Portfolio's high quality criteria.

Investment adviser

          As stated in the Prospectus, the Portfolio has an Investment Advisory
          Agreement with Janus Capital, 100 Fillmore Street, Denver, Colorado
          80206-4928. The Advisory Agreement provides that Janus Capital will
          furnish continuous advice and recommendations concerning the
          Portfolio's investments, provide office space for the Portfolio and
          pay the salaries, fees and expenses of all Portfolio officers and of
          those Trustees who are affiliated with Janus Capital. Janus Capital
          also may make payments to selected broker-dealer firms or institutions
          which were instrumental in the acquisition of shareholders for the
          Portfolio or which performed services with respect to shareholder
          accounts. The minimum aggregate size required for eligibility for such
          payments, and the factors in selecting the broker-dealer firms and
          institutions to which they will be made, are determined from time to
          time by Janus Capital. Janus Capital is also authorized to perform the
          management and administrative services necessary for the operation of
          the Portfolio.

          The Portfolio pays custodian agent fees and expenses, brokerage
          commissions and dealer spreads and other expenses in connection with
          the execution of Portfolio transactions, legal and accounting
          expenses, interest and taxes, registration fees, expenses of
          shareholders' meetings, and reports to shareholders, fees and expenses
          of Trustees who are not affiliated with Janus Capital, and other costs
          of complying with applicable laws regulating the sale of Portfolio
          shares. Pursuant to the Advisory Agreement, Janus Capital furnishes
          certain other services, including net asset value determination,
          portfolio accounting and record keeping for which the Portfolio may
          reimburse Janus Capital for its costs.

          The Portfolio has agreed to compensate Janus Capital for its advisory
          services by the monthly payment of an advisory fee at the annual rate
          of .25% of the Portfolio's average daily net assets. Janus Capital has
          agreed to reimburse the Portfolio by the amount, if any, that the
          Portfolio's normal operating expenses in any fiscal year, including
          the investment advisory fee but excluding the distribution fee
          described below, brokerage commissions, interest, taxes and
          extraordinary expenses, exceed .50% of average daily net assets. Janus
          Capital has agreed to continue such waivers until at least the next
          annual renewal of the advisory agreements. Mortality risk, expense
          risk and other charges imposed by participating insurance companies
          are also excluded from the above expense limitation.

          For the fiscal year ended December 31, 1998, the advisory fee was
          $79,201. For the fiscal year ended December 31, 1997 and December 31,
          1996, the advisory fees were $22,333 and $9,287, respectively. For the
          fiscal years ended December 31, 1997 and December 31, 1996, Janus
          Capital waived $2,184 and $9,287, respectively (the advisory fee
          waivers by Janus Capital exceeded the advisory fees for 1996).

          The Advisory Agreement is dated July 1, 1997 and will continue in
          effect from year to year so long as such continuance is approved
          annually by a majority of the Portfolio's Trustees who are not parties
          to the Advisory Agreement or interested persons of any such party, and
          by either a majority of the outstanding voting shares or the Trustees.
          The Advisory Agreement i) may be terminated without the payment of any
          penalty by the Portfolio or Janus Capital on 60 days' written notice;
          ii) terminates automatically in the event of its assignment; and iii)
          generally, may not be amended without the approval by vote of a
          majority of the Trustees, including the Trustees who are not
          interested persons of the Portfolio or Janus Capital and, to the
          extent required by the 1940 Act, the vote of a majority of the
          outstanding voting securities of the Portfolio.

          Janus Capital also acts as sub-advisor for a number of private-label
          mutual funds and provides separate account advisory services for
          institutional accounts. Investment decisions for each account managed
          by Janus Capital, including the Portfolio, are made independently from
          those for any other account that is or may in the future become
          managed by Janus Capital or its affiliates. If, however, a number of
          accounts managed by Janus Capital are contemporaneously engaged in the
          purchase or sale of the same security, the orders may be aggregated
          and/or the transactions may be averaged as to price and allocated
          equitably to

                                                                              13

          each account. In some cases, this policy might adversely affect the
          price paid or received by an account or the size of the position
          obtained or liquidated for an account. Pursuant to an exemptive order
          granted by the SEC, the Portfolio and other funds advised by Janus
          Capital may also transfer daily uninvested cash balances into one or
          more joint trading accounts. Assets in the joint trading accounts are
          invested in money market instruments and the proceeds are allocated to
          the participating funds on a pro rata basis.

          Kansas City Southern Industries, Inc. ("KCSI") owns approximately 82%
          of the outstanding voting stock of Janus Capital, most of which it
          acquired in 1984. KCSI is a publicly traded holding company whose
          primary subsidiaries are engaged in transportation, information
          processing and financial services. Thomas H. Bailey, President and
          Chairman of the Board of Janus Capital, owns approximately 12% of its
          voting stock and, by agreement with KCSI, selects a majority of Janus
          Capital's Board.


          KCSI has announced its intention to separate its transportation and
          financial services businesses. KCSI anticipates the separation to be
          completed in the first quarter of 2000.


          Each account managed by Janus Capital has its own investment objective
          and is managed in accordance with that objective by a particular
          portfolio manager or team of portfolio managers. As a result, from
          time to time two or more different managed accounts may pursue
          divergent investment strategies with respect to investments or
          categories of investments.

          Janus Capital does not permit portfolio managers to purchase and sell
          securities for their own accounts except under the limited exceptions
          contained in Janus Capital's policy regarding personal investing by
          directors, officers and employees of Janus Capital and the Portfolio.
          The policy requires investment personnel and officers of Janus
          Capital, inside directors of Janus Capital and the Portfolio and other
          designated persons deemed to have access to current trading
          information to pre-clear all transactions in securities not otherwise
          exempt under the policy. Requests for trading authority will be denied
          when, among other reasons, the proposed personal transaction would be
          contrary to the provisions of the policy or would be deemed to
          adversely affect any transaction then known to be under consideration
          for or to have been effected on behalf of any client account,
          including the Portfolio.

          In addition to the pre-clearance requirement described above, the
          policy subjects investment personnel, officers and directors/Trustees
          of Janus Capital and the Trust to various trading restrictions and
          reporting obligations. All reportable transactions are required to be
          reviewed for compliance with Janus Capital's policy. Those persons
          also may be required under certain circumstances to forfeit their
          profits made from personal trading.

          The provisions of the policy are administered by and subject to
          exceptions authorized by Janus Capital.

Custodian, transfer agent and certain affiliations

          Citibank, N.A., 111 Wall Street, 24th Floor, Zone 5, New York, NY
          10043, is the Portfolio's custodian. The custodian holds the
          Portfolio's assets in safekeeping and collects and remits the income
          thereon, subject to the instructions of the Portfolio.

          Janus Service Corporation, P.O. Box 173375, Denver, Colorado
          80217-3375, a wholly-owned subsidiary of Janus Capital, is the
          Portfolio's transfer agent. In addition, Janus Service provides
          certain other administrative, recordkeeping and shareholder relations
          services to the Portfolio. Janus Service is not compensated for its
          services related to the Shares, except for out-of-pocket costs.

          Janus Distributors, Inc. ("Janus Distributors"), 100 Fillmore Street,
          Denver, Colorado 80206-4928, a wholly-owned subsidiary of Janus
          Capital, is a distributor of the Portfolio. Janus Distributors is
          registered as a broker-dealer under the Securities Exchange Act of
          1934 (the "Exchange Act") and is a member of the National Association
          of Securities Dealers, Inc.

          The Portfolio pays DST Systems, Inc., a subsidiary of KCSI, license
          fees at the rate of $3.98 per shareholder account for the use of DST's
          shareholder accounting system. The Portfolio also pays DST $1.10 per
          closed shareholder account. The Portfolio pays DST for the use of its
          portfolio and fund accounting system a monthly base fee of $250 to
          $1,250 per month based on the number of Janus funds using the system
          and an asset charge of $1 per million dollars of net assets (not to
          exceed $500 per month).

          The Trustees have authorized the Portfolio to use another affiliate of
          DST as introducing broker for certain Portfolio transactions as a
          means to reduce Portfolio expenses through credits against the charges
          of DST and its affiliates with regard to commissions earned by such
          affiliate. See "Portfolio Transactions and Brokerage."

                                                                              15

Portfolio transactions and brokerage

          Decisions as to the assignment of portfolio business for the Portfolio
          and negotiation of its commission rates are made by Janus Capital
          whose policy is to obtain the "best execution" (prompt and reliable
          execution at the most favorable security price) of all portfolio
          transactions.

          In selecting brokers and dealers and in negotiating commissions, Janus
          Capital considers a number of factors, including but not limited to:
          Janus Capital's knowledge of currently available negotiated commission
          rates or prices of securities currently available and other current
          transaction costs; the nature of the security being traded; the size
          and type of the transaction; the nature and character of the markets
          for the security to be purchased or sold; the desired timing of the
          trade; the activity existing and expected in the market for the
          particular security; confidentiality; the quality of the execution,
          clearance and settlement services; financial stability of the broker
          or dealer; the existence of actual or apparent operational problems of
          any broker or dealer; and research products or services provided. In
          recognition of the value of the foregoing factors, Janus Capital may
          place portfolio transactions with a broker or dealer with whom it has
          negotiated a commission that is in excess of the commission another
          broker or dealer would have charged for effecting that transaction if
          Janus Capital determines in good faith that such amount of commission
          was reasonable in relation to the value of the brokerage and research
          provided by such broker or dealer viewed in terms of either that
          particular transaction or of the overall responsibilities of Janus
          Capital. These research and other services may include, but are not
          limited to, general economic and security market reviews, industry and
          company reviews, evaluations of securities, recommendations as to the
          purchase and sale of securities, and access to third party
          publications, computer and electronic equipment and software. Research
          received from brokers or dealers is supplemental to Janus Capital's
          own research efforts.

          For the fiscal years ended December 31, 1998, December 31, 1997 and
          December 31, 1996, the Portfolio did not incur any brokerage
          commissions. The Portfolio generally buys and sells securities in
          principal and agency transactions in which no commissions are paid.
          However, the Portfolio may engage an agent and pay commissions for
          such transactions if Janus Capital believes that the net result of the
          transaction to the Portfolio will be no less favorable than that of
          contemporaneously available principal transactions.

          Janus Capital may use research products and services in servicing
          other accounts in addition to the Portfolio. If Janus Capital
          determines that any research product or service has a mixed use, such
          that it also serves functions that do not assist in the investment
          decision-making process, Janus Capital may allocate the costs of such
          service or product accordingly. Only that portion of the product or
          service that Janus Capital determines will assist it in the investment
          decision-making process may be paid for in brokerage commission
          dollars. Such allocation may create a conflict of interest for Janus
          Capital.

          Janus Capital may consider sales of Portfolio shares or shares of
          other Janus funds by a broker-dealer or the recommendation of a
          broker-dealer to its customers that they purchase such shares as a
          factor in the selection of broker-dealers to execute Portfolio
          transactions. Janus Capital may also consider payments made by brokers
          effecting transactions for a Portfolio i) to the Portfolio or ii) to
          other persons on behalf of the Portfolio for services provided to the
          Portfolio for which it would be obligated to pay. In placing portfolio
          business with such broker-dealers, Janus Capital will seek the best
          execution of each transaction.

          When the Portfolio purchases or sells a security in the
          over-the-counter market, the transaction takes place directly with a
          principal market-maker, without the use of a broker, except in those
          circumstances where in the opinion of Janus Capital better prices and
          executions will be achieved through the use of a broker.

Purchase of Shares

          Shares of the Portfolio can be purchased only by (i) the separate
          accounts of participating insurance companies for the purpose of
          funding variable insurance contracts and (ii) qualified plans.
          Participating insurance companies and certain designated organizations
          are authorized to receive purchase orders on the Portfolio's behalf,
          and those organizations are authorized to designate their agents and
          affiliates as intermediaries to receive purchase orders. Purchase
          orders are deemed received by the Portfolio when authorized
          organizations, their agents or affiliates receive the order. The
          Portfolio is not responsible for the failure of any designated
          organization or its agents or affiliates to carry out its obligations
          to its customers. Shares of the Portfolio are purchased at the NAV per
          share as determined at the close of regular trading session of the New
          York Stock Exchange next occurring after a purchase order is received
          and accepted by the Portfolio or its authorized agent. In order to
          receive a day's dividend, your order must be received by the close of
          the regular trading session of the NYSE. The prospectus for your
          insurance company's separate account or your plan documents contain
          detailed information about investing in the Portfolio.

Distribution and Shareholder Servicing plan

          Under a distribution and shareholder servicing plan ("Plan") adopted
          in accordance with Rule 12b-1 under the Investment Company Act of 1940
          (the "1940 Act"), the Shares may pay Janus Distributors, Inc., the
          Trust's distributor, a fee at an annual rate of up to 0.25% of the
          average daily net assets of the Shares of the Portfolio. Under the
          terms of the Plan, the Trust is authorized to make payments to Janus
          Distributors for remittance to insurance companies and qualified plan
          service providers as compensation for distribution and shareholder
          servicing performed by such service providers. The Plan is a
          compensation type plan and permits the payment at an annual rate of up
          to 0.25% of the average daily net assets of the Shares of a Portfolio
          for recordkeeping and administrative services as well as activities
          which are primarily intended to result in sales of the Shares,
          including but not limited to preparing, printing and distributing
          prospectuses, Statements of Additional Information, shareholder
          reports, and educational materials to prospective and existing
          contract owners and plan participants; responding to inquiries by
          contract owners and plan participants; receiving and answering
          correspondence; contract owner and participant level recordkeeping and
          administrative services; and similar activities. On September 14,
          1999, Trustees unanimously approved the Plan which became effective on
          that date. The Plan and any Rule 12b-1 related agreement that is
          entered into by the Portfolio or Janus Distributors in connection with
          the Plan will continue in effect for a period of more than one year
          only so long as continuance is specifically approved at least annually
          by a vote of a majority of the Trustees, and of a majority of the
          Trustees who are not interested persons (as defined in the 1940 Act)
          of the Trust and who have no direct or indirect financial interest in
          the operation of the Plan or any related agreements ("12b-1
          Trustees"). All material amendments to the Plan must be approved by a
          majority vote of the Trustees, including a majority of the 12b-1
          Trustees, at a meeting called for that purpose. In addition, the Plan
          may be terminated at any time, without penalty, by vote of a majority
          of the outstanding Shares of the Portfolio or by vote of a majority of
          12b-1 Trustees.

                                                                              23

Redemption of Shares

          Redemptions, like purchases, may only be effected through the separate
          accounts of participating insurance companies or qualified plans.
          Certain designated organizations are authorized to receive redemption
          orders on the Portfolio's behalf and those organizations are
          authorized to designate their agents and affiliates as intermediaries
          to receive redemption orders. Redemption orders are deemed received by
          the Portfolio when authorized organizations, their agents or
          affiliates receive the order. The Portfolio is not responsible for the
          failure of any designated organization or its agents or affiliates to
          carry out its obligations to its customers. Shares normally will be
          redeemed for cash, although the Portfolio retains the right to redeem
          its shares in kind under unusual circumstances, in order to protect
          the interests of remaining shareholders, by delivery of securities
          selected from its assets at its discretion. However, the Portfolio is
          governed by Rule 18f-1 under the 1940 Act, which requires the
          Portfolio to redeem shares solely in cash up to the lesser of $250,000
          or 1% of the net asset value of the Portfolio during any 90-day period
          for any one shareholder. Should redemptions by any shareholder exceed
          such limitation, the Portfolio will have the option of redeeming the
          excess in cash or in kind. If shares are redeemed in kind, the
          redeeming shareholder might incur brokerage costs in converting the
          assets to cash. The method of valuing securities used to make
          redemptions in kind will be the same as the method of valuing
          portfolio securities described under "Determination of Net Asset
          Value" and such valuation will be made as of the same time the
          redemption price is determined.

          The right to require the Portfolio to redeem its shares may be
          suspended, or the date of payment may be postponed, whenever (1)
          trading on the NYSE is restricted, as determined by the SEC, or the
          NYSE is closed except for holidays and weekends, (2) the SEC permits
          such suspension and so orders, or (3) an emergency exists as
          determined by the SEC so that disposal of securities or determination
          of NAV is not reasonably practicable.

Dividends and tax status

          Dividends representing substantially all of the net investment income
          and any net realized gains on sales of securities are declared daily,
          Saturdays, Sundays and holidays included, and distributed on the last
          business day of each month. If a month begins on a Saturday, Sunday,
          or holiday, dividends for those days are declared at the end of the
          preceding month and distributed on the first business day of the
          month. The Portfolio intends to qualify as a regulated investment
          company by satisfying certain requirements prescribed by Subchapter M
          of the Code. In addition, because a class of shares of the Portfolio
          are sold in connection with variable insurance contracts, the
          Portfolio intends to comply with the diversification requirements of
          Internal Revenue Code Section 817(h) related to the tax-deferred
          status of insurance company separate accounts.

          All income dividends on the Portfolio's Shares are reinvested
          automatically in additional Shares of the Portfolio at the NAV
          determined on the first business day following the record date.

          Because Shares of the Portfolio can only be purchased through variable
          insurance contracts or qualified plans, it is anticipated that any
          income dividends or capital gains distributions will be exempt from
          current taxation if left to accumulate within such plans. See the
          prospectus for the separate account of the related insurance company
          or the plan documents for additional information.

                                                                              25

Miscellaneous information

          The Portfolio is an open-end management investment company registered
          under the 1940 Act as a series of the Trust, which was organized as a
          Delaware business trust on May 20, 1993. The Trust Instrument permits
          the Trustees to issue an unlimited number of shares of beneficial
          interest from an unlimited number of series and classes of shares. As
          of the date of this SAI, the Trust consists of eleven series of
          shares, known as "portfolios," in three classes. Additional series
          and/or classes may be created from time to time.

SHARES OF THE TRUST

          The Trust is authorized to issue an unlimited number of shares of
          beneficial interest with a par value of $0.001 per share for each
          series of the Trust. Shares of each series of the Trust are fully paid
          and nonassessable when issued. The Shares of the Portfolio participate
          equally in dividends and other distributions by the Portfolio, and in
          residual assets of the Portfolio in the event of liquidation. Shares
          of the Portfolio have no preemptive, conversion or subscription
          rights.

          The Portfolio currently offers three classes of shares. The Shares
          discussed in this SAI are offered only in connection with investment
          in and payments under variable insurance contracts and to qualified
          retirement plans that require a fee from Portfolio assets to procure
          distribution and administrative services to contract owners and plan
          participants. A second class of shares, Retirement Shares, is offered
          only to qualified plans whose service providers require a fee from
          Trust assets for providing certain services to plan participants. The
          third class of shares, Institutional Shares, are offered only in
          connection with investment in and payments under variable contracts
          and life insurance contracts, as well as certain qualified retirement
          plans.

SHAREHOLDER MEETINGS

          The Trust does not intend to hold annual shareholder meetings.
          However, special meetings may be called for the Portfolio or for the
          Trust as a whole for purposes such as electing or removing Trustees,
          terminating or reorganizing the Trust, changing fundamental policies,
          or for any other purpose requiring a shareholder vote under the 1940
          Act. Separate votes are taken by the Portfolio or class only if a
          matter affects or requires the vote of only the Portfolio or class or
          the Portfolio's or class' interest in the matter differs from the
          interest of the other portfolios or class of the Trust. A shareholder
          is entitled to one vote for each Share owned.

VOTING RIGHTS

          A participating insurance company issuing a variable insurance
          contract will vote shares in the separate account as required by law
          and interpretations thereof, as may be amended or changed from time to
          time. In accordance with current law and interpretations, a
          participating insurance company is required to request voting
          instructions from policy owners and must vote shares in the separate
          account, including shares for which no instructions have been
          received, in proportion to the voting instructions received.
          Additional information may be found in the participating insurance
          company's separate account prospectus.

          The Trustees are responsible for major decisions relating to the
          Portfolio's policies and objectives; the Trustees oversee the
          operation of the Portfolio by its officers.

          The present Trustees were elected by the initial trustee of the Trust
          on May 25, 1993, and were approved by the initial shareholder on May
          25, 1993 with the exception of Mr. Craig and Mr. Rothe who were
          appointed by the Trustees as of June 30, 1995 and as of January 1,
          1997, respectively. Under the Trust Instrument, each Trustee will
          continue in office until the termination of the Trust or his earlier
          death, retirement, resignation, bankruptcy, incapacity or removal.
          Vacancies will be filled by a majority of the remaining Trustees,
          subject to the 1940 Act. Therefore, no annual or regular meetings of
          shareholders

 26
<PAGE>

          normally will be held, unless otherwise required by the Trust
          Instrument or the 1940 Act. Subject to the foregoing, shareholders
          have the power to vote to elect or remove Trustees, to terminate or
          reorganize the Portfolio, to amend the Trust Instrument, to bring
          certain derivative actions and on any other matters on which a
          shareholder vote is required by the 1940 Act, the Trust Instrument,
          the Trust's Bylaws or the Trustees.

          As mentioned in "Shareholder Meetings", each share of each portfolio
          of the Trust has one vote (and fractional votes for fractional
          shares). Shares of all portfolios of the Trust have noncumulative
          voting rights, which means that the holders of more than 50% of the
          shares of all portfolios of the Trust voting for the election of
          Trustees can elect 100% of the Trustees if they choose to do so and,
          in such event, the holders of the remaining shares will not be able to
          elect any Trustees. Each portfolio or class of the Trust will vote
          separately only with respect to those matters that affect only that
          portfolio or class or if an interest of a portfolio or class in the
          matter differs from the interests of other portfolios or classes of
          the Trust.

Appendix A

DESCRIPTION OF SECURITIES RATINGS

Moody's and Standard & Poor's

          MUNICIPAL AND CORPORATE BONDS AND MUNICIPAL LOANS

          The two highest ratings of Standard & Poor's Ratings Services ("S&P")
          for municipal and corporate bonds are AAA and AA. Bonds rated AAA have
          the highest rating assigned by S&P to a debt obligation. Capacity to
          pay interest and repay principal is extremely strong. Bonds rated AA
          have a very strong capacity to pay interest and repay principal and
          differ from the highest rated issues only in a small degree. The AA
          rating may be modified by the addition of a plus (+) or minus (-) sign
          to show relative standing within that rating category.

          The two highest ratings of Moody's Investors Service, Inc. ("Moody's")
          for municipal and corporate bonds are Aaa and Aa. Bonds rated Aaa are
          judged by Moody's to be of the best quality. Bonds rated Aa are judged
          to be of high quality by all standards. Together with the Aaa group,
          they comprise what are generally known as high-grade bonds. Moody's
          states that Aa bonds are rated lower than the best bonds because
          margins of protection or other elements make long-term risks appear
          somewhat larger than Aaa securities. The generic rating Aa may be
          modified by the addition of the numerals 1, 2 or 3. The modifier 1
          indicates that the security ranks in the higher end of the Aa rating
          category; the modifier 2 indicates a mid-range ranking; and the
          modifier 3 indicates that the issue ranks in the lower end of such
          rating category.

          SHORT TERM MUNICIPAL LOANS

          S&P's highest rating for short-term municipal loans is SP-1. S&P
          states that short-term municipal securities bearing the SP-1
          designation have a strong capacity to pay principal and interest.
          Those issues rated SP-1 which are determined to possess a very strong
          capacity to pay debt service will be given a plus (+) designation.
          Issues rated SP-2 have satisfactory capacity to pay principal and
          interest with some vulnerability to adverse financial and economic
          changes over the term of the notes.

          Moody's highest rating for short-term municipal loans is MIG-1/VMIG-1.
          Moody's states that short-term municipal securities rated MIG-1/VMIG-1
          are of the best quality, enjoying strong protection from established
          cash flows of funds for their servicing or from established and
          broad-based access to the market for refinancing, or both. Loans
          bearing the MIG-2/VMIG-2 designation are of high quality, with margins
          of protection ample although not so large as in the MIG-1/VMIG-1
          group.

          OTHER SHORT-TERM DEBT SECURITIES

          Prime-1 and Prime-2 are the two highest ratings assigned by Moody's
          for other short-term debt securities and commercial paper, and A-1 and
          A-2 are the two highest ratings for commercial paper assigned by S&P.
          Moody's uses the numbers 1, 2 and 3 to denote relative strength within
          its highest classification of Prime, while S&P uses the numbers 1, 2
          and 3 to denote relative strength within its highest classification of
          A. Issuers rated Prime-1 by Moody's have a superior ability for
          repayment of senior short-term debt obligations and have many of the
          following characteristics: leading market positions in
          well-established industries, high rates of return on funds employed,
          conservative capitalization structure with moderate reliance on debt
          and ample asset protection, broad margins in earnings coverage of
          fixed financial charges and high internal cash generation, and well
          established access to a range of financial markets and assured sources
          of alternate liquidity. Issuers rated Prime-2 by Moody's have a strong
          ability for repayment of senior short-term debt obligations and
          display many of the same characteristics displayed by issuers rated

Appendix B

DESCRIPTION OF MUNICIPAL SECURITIES

          MUNICIPAL NOTES generally are used to provide for short-term capital
          needs and usually have maturities of one year or less. They include
          the following:

          1. Project Notes, which carry a U.S. government guarantee, are issued
          by public bodies (called "local issuing agencies") created under the
          laws of a state, territory, or U.S. possession. They have maturities
          that range up to one year from the date of issuance. Project Notes are
          backed by an agreement between the local issuing agency and the
          Federal Department of Housing and Urban Development. These Notes
          provide financing for a wide range of financial assistance programs
          for housing, redevelopment, and related needs (such as low-income
          housing programs and renewal programs).

          2. Tax Anticipation Notes are issued to finance working capital needs
          of municipalities. Generally, they are issued in anticipation of
          various seasonal tax revenues, such as income, sales, use and business
          taxes, and are payable from these specific future taxes.

          3. Revenue Anticipation Notes are issued in expectation of receipt of
          other types of revenues, such as Federal revenues available under the
          Federal Revenue Sharing Programs.

          4. Bond Anticipation Notes are issued to provide interim financing
          until long-term financing can be arranged. In most cases, the
          long-term bonds then provide the money for the repayment of the Notes.

          5. Construction Loan Notes are sold to provide construction financing.
          After successful completion and acceptance, many projects receive
          permanent financing through the Federal Housing Administration under
          the Federal National Mortgage Association ("Fannie Mae") or the
          Government National Mortgage Association ("Ginnie Mae").

          6. Tax-Exempt Commercial Paper is a short-term obligation with a
          stated maturity of 365 days or less. It is issued by agencies of state
          and local governments to finance seasonal working capital needs or as
          short-term financing in anticipation of longer term financing.

          MUNICIPAL BONDS, which meet longer term capital needs and generally
          have maturities of more than one year when issued, have three
          principal classifications:

          1. General Obligation Bonds are issued by such entities as states,
          counties, cities, towns, and regional districts. The proceeds of these
          obligations are used to fund a wide range of public projects,
          including construction or improvement of schools, highways and roads,
          and water and sewer systems. The basic security behind General
          Obligation Bonds is the issuer's pledge of its full faith and credit
          and taxing power for the payment of principal and interest. The taxes
          that can be levied for the payment of debt service may be limited or
          unlimited as to the rate or amount of special assessments.

          2. Revenue Bonds in recent years have come to include an increasingly
          wide variety of types of municipal obligations. As with other kinds of
          municipal obligations, the issuers of revenue bonds may consist of
          virtually any form of state or local governmental entity, including
          states, state agencies, cities, counties, authorities of various
          kinds, such as public housing or redevelopment authorities, and
          special districts, such as water, sewer or sanitary districts.
          Generally, revenue bonds are secured by the revenues or net revenues
          derived from a particular facility, group of facilities, or, in some
          cases, the proceeds of a special excise or other specific revenue
          source. Revenue bonds are issued to finance a wide variety of capital
          projects including electric, gas, water and sewer systems; highways,
          bridges, and tunnels; port and airport facilities; colleges and
          universities; and hospitals. Many of these bonds provide additional
          security in the form of a debt service reserve fund to be used to make
          principal and interest payments. Various forms of credit enhancement,
          such as a bank letter of credit or municipal bond insurance, may also
          be employed in revenue bond issues. Housing authorities have a wide
          range of security, including partially or fully insured mortgages,
          rent subsidized and/or collateralized mortgages, and/or the net
          revenues from housing or other

 32
<PAGE>

          public projects. Some authorities provide further security in the form
          of a state's ability (without obligation) to make up deficiencies in
          the debt service reserve fund.

          In recent years, revenue bonds have been issued in large volumes for
          projects that are privately owned and operated (see 3 below).

          3. Private Activity Bonds are considered municipal bonds if the
          interest paid thereon is exempt from Federal income tax and are issued
          by or on behalf of public authorities to raise money to finance
          various privately operated facilities for business and manufacturing,
          housing and health. These bonds are also used to finance public
          facilities such as airports, mass transit systems and ports. The
          payment of the principal and interest on such bonds is dependent
          solely on the ability of the facility's user to meet its financial
          obligations and the pledge, if any, of real and personal property as
          security for such payment.

          While, at one time, the pertinent provisions of the Internal Revenue
          Code permitted private activity bonds to bear tax-exempt interest in
          connection with virtually any type of commercial or industrial project
          (subject to various restrictions as to authorized costs, size
          limitations, state per capita volume restrictions, and other matters),
          the types of qualifying projects under the Code have become
          increasingly limited, particularly since the enactment of the Tax
          Reform Act of 1986. Under current provisions of the Code, tax-exempt
          financing remains available, under prescribed conditions, for certain
          privately owned and operated rental multi-family housing facilities,
          nonprofit hospital and nursing home projects, airports, docks and
          wharves, mass commuting facilities and solid waste disposal projects,
          among others, and for the refunding (that is, the tax-exempt
          refinancing) of various kinds of other private commercial projects
          originally financed with tax-exempt bonds. In future years, the types
          of projects qualifying under the Code for tax-exempt financing are
          expected to become increasingly limited.

          Because of terminology formerly used in the Internal Revenue Code,
          virtually any form of private activity bond may still be referred to
          as an "industrial development bond," but more and more frequently
          revenue bonds have become classified according to the particular type
          of facility being financed, such as hospital revenue bonds, nursing
          home revenue bonds, multi-family housing revenues bonds, single family
          housing revenue bonds, industrial development revenue bonds, solid
          waste resource recovery revenue bonds, and so on.

          OTHER MUNICIPAL OBLIGATIONS, incurred for a variety of financing
          purposes, include: municipal leases, which may take the form of a
          lease or an installment purchase or conditional sale contract, are
          issued by state and local governments and authorities to acquire a
          wide variety of equipment and facilities such as fire and sanitation
          vehicles, telecommunications equipment and other capital assets.
          Municipal leases frequently have special risks not normally associated
          with general obligation or revenue bonds. Leases and installment
          purchase or conditional sale contracts (which normally provide for
          title to the leased asset to pass eventually to the government issuer)
          have evolved as a means for governmental issuers to acquire property
          and equipment without meeting the constitutional and statutory
          requirements for the issuance of debt. The debt-issuance limitations
          of many state constitutions and statutes are deemed to be inapplicable
          because of the inclusion in many leases or contracts of
          "non-appropriation" clauses that provide that the governmental issuer
          has no obligation to make future payments under the lease or contract
          unless money is appropriated for such purpose by the appropriate
          legislative body on a yearly or other periodic basis. To reduce this
          risk, the Fund will only purchase municipal leases subject to a
          non-appropriation clause when the payment of principal and accrued
          interest is backed by an unconditional irrevocable letter of credit,
          or guarantee of a bank or other entity that meets the criteria
          described in the Prospectus.

                                                                              33
<PAGE>

          Tax-exempt bonds are also categorized according to whether the
          interest is or is not includible in the calculation of alternative
          minimum taxes imposed on individuals, according to whether the costs
          of acquiring or carrying the bonds are or are not deductible in part
          by banks and other financial institutions, and according to other
          criteria relevant for Federal income tax purposes. Due to the
          increasing complexity of Internal Revenue Code and related
          requirements governing the issuance of tax-exempt bonds, industry
          practice has uniformly required, as a condition to the issuance of
          such bonds, but particularly for revenue bonds, an opinion of
          nationally recognized bond counsel as to the tax-exempt status of
          interest on the bonds.
