                             ________________, 2000


To the Shareholders of Sit Regional Growth Fund:

         I am writing to inform you of a Special Meeting of the shareholders of
Sit Regional Growth Fund ("Regional Fund"), a series of Sit Mutual Funds, Inc.,
that will be held at a.m. on , 2000 at the offices of Sit Investment Associates,
Inc., 4600 Norwest Center, 90 South Seventh Street, Minneapolis, Minnesota. The
purpose of this meeting is to vote on a proposal to combine Regional Fund into
Sit Large Cap Growth Fund, Inc. ("Large Cap Fund"). If the proposed
reorganization is approved, you will receive shares of Large Cap Fund with a
value equal to the value of your Regional Fund shares.

         The attached Prospectus/Proxy Statement provides you with additional
information about the proposed reorganization and a comparison of the two Funds.
There is also attached a "Q&A" which should provide answers to many of your
questions. We urge you to read all of the enclosed materials carefully.

         Sit Mutual Funds' Board of Directors has approved the proposed
combination of the Funds and recommends it for your approval. I encourage you to
vote "FOR" the proposal, and ask that you please send your completed proxy
ballot in as soon as possible to help save the cost of additional solicitations.
As always, we thank you for your confidence and support.

                                     Sincerely,



                                     Mary K. Stern
                                     President

                           WHAT YOU SHOULD KNOW ABOUT
                        THIS PROPOSED FUND REORGANIZATION


         THE BOARD OF DIRECTORS OF SIT MUTUAL FUNDS ENCOURAGES YOU TO READ THE
ENCLOSED PROSPECTUS/PROXY STATEMENT CAREFULLY. THE FOLLOWING IS A BRIEF OVERVIEW
OF THE KEY ISSUES.

WHY IS MY FUND HOLDING A SPECIAL SHAREHOLDERS MEETING?

         The meeting is being called to ask you to approve the reorganization of
Regional Fund into Large Cap Fund, a similar fund in the Sit fund family. If
shareholders vote in favor of the reorganization, Large Cap Fund will acquire
all of the assets of Regional Fund and your shares of Regional Fund will be
exchanged for shares of Large Cap Fund with the same net asset value.

WHY WAS THE REORGANIZATION PROPOSED?

         Sit Investment Associates, Inc. (the "Adviser), the investment adviser
to both Regional Fund and Large Cap Fund, recommended the reorganization to the
Board because it believes that Regional Fund is unlikely to grow to a size that
is economically viable. At December 31, 1999, Regional Fund has net assets of
less than $8 million. The small size of the Fund makes portfolio management
difficult. The Fund cannot maintain the level of investment diversification that
the Adviser desires. In addition, the Fund's midwestern geographic focus
precludes the Fund from taking advantage of a number of investment opportunities
available in other areas of the country. Large Cap Fund is a much larger Fund,
with net assets of approximately $164 million at December 31, 1999. Therefore,
Large Cap Fund is able to achieve greater investment diversification. In
addition, Large Cap Fund is not subject to any geographic limitations on its
investments.

ARE THERE ANY OTHER ADVANTAGES TO MERGING THE FUNDS?

         The contractual advisory fee for Large Cap Fund is lower than for
Regional Fund. Because the Adviser pays all Fund expenses (other than interest,
brokerage commissions, transaction charges and certain extraordinary expenses),
overall expenses will be lower for Large Cap Fund. During the past year, the
Adviser waived fees for Regional Fund so that overall expenses were the same for
the two Funds. However, the Adviser is not obligated to continue these waivers
after December 31, 2000.

         The potential benefits and possible disadvantages of merging the Funds
are explained in more detail in the enclosed Prospectus/Proxy Statement.

HOW ARE REGIONAL FUND AND LARGE CAP FUND ALIKE?  HOW DO THEY DIFFER?

         The investment objectives of these Funds are identical; each has an
objective of maximizing long-term capital appreciation. In addition, each Fund
invests in growth-oriented companies that the Adviser believes exhibit the
potential for superior growth. However, there are differences in the Funds'
investment strategies:

         o        Large Cap Fund invests at least 65% of its total assets in
                  stocks of large cap companies - that is, companies with
                  capitalizations of $5 billion or more at the time of purchase.

         o        Regional Fund's investments include stocks of small, mid and
                  large cap companies.

         o        Large Cap Fund invests primarily in stocks of domestic
                  companies, but is not subject to any other geographic
                  limitation on its investments.



<PAGE>



         o        Regional Fund invests at least 80% of its total assets in
                  common stocks of companies with their headquarters in a
                  midwest region comprised of Minnesota, Iowa, Missouri, North
                  Dakota, South Dakota, Nebraska, Kansas, Wisconsin, Illinois,
                  Michigan, Indiana and Ohio.

WHAT HAPPENS IF SHAREHOLDERS DECIDE IN FAVOR OF A REORGANIZATION?

         A closing date will be set for the reorganization. Shareholders will
receive full and fractional shares of Large Cap Fund equal in value to the
shares of Regional Fund that they owned immediately prior to the reorganization.

IF THE FUNDS MERGE, WILL THERE BE TAX CONSEQUENCES FOR ME?

         Unlike a transaction where you sell shares of one fund in order to buy
shares of another, the reorganization will not be considered a taxable event.
The Funds themselves will recognize no gains or losses on assets as a result of
the reorganization. So you will not have reportable capital gains or losses due
to the reorganization.

         However, you should consult your own tax advisor regarding any possible
effect the proposed reorganization might have on you, given your personal
circumstances - particularly regarding state and local taxes.

WHO WILL PAY FOR THIS REORGANIZATION?

         The expenses of the reorganization, including legal expenses, printing,
packaging and postage, plus the costs of any supplementary solicitation, will be
borne by the Adviser.

WHAT DOES THE BOARD OF DIRECTORS RECOMMEND?

         The Board of Directors recommends that you vote in favor of the
reorganization. Before you do, however, be sure to study the issues involved and
call us with any questions, then vote promptly to ensure that a quorum will be
represented at the special shareholders meeting.

WHERE DO I GET MORE INFORMATION ABOUT LARGE CAP GROWTH FUND?

         Please call the Fund at (800) 332-5580 or (612) 334-5888.

         1.       To consider and vote on a proposed Agreement and Plan of
                  Reorganization (the "Plan") providing for (a) the acquisition
                  of substantially all of the assets and the assumption of all
                  liabilities of Regional Fund by Sit Large Cap Growth Fund,
                  Inc. ("Large Cap Fund") in exchange for shares of common stock
                  of Large Cap Fund having an aggregate net asset value equal to
                  the aggregate value of the assets acquired (less the
                  liabilities assumed) of Regional Fund and (b) the liquidation
                  of Regional Fund and the pro rata distribution of Large Cap
                  Fund shares to Regional Fund shareholders. Under the Plan,
                  each Regional Fund shareholder will receive Large Cap Fund
                  shares with a net asset value equal as of the effective time
                  of the Plan to the net asset value of their Regional Fund
                  shares. A vote in favor of the Plan will be considered a vote
                  in favor of an amendment to the articles of incorporation of
                  Sit Mutual Funds required to effect the reorganization
                  contemplated by the Plan.

         2.       To transact such other business as may properly come before

PLAN.

record date for the determination of shareholders entitled to notice of and to

             ACQUISITION OF THE ASSETS OF SIT REGIONAL GROWTH FUND,
                       A SERIES OF SIT MUTUAL FUNDS, INC.,
        BY AND IN EXCHANGE FOR SHARES OF SIT LARGE CAP GROWTH FUND, INC.


         We are furnishing this combined Prospectus/Proxy Statement to the
shareholders of Sit Regional Growth Fund ("Regional Fund"), a series of Sit
Mutual Funds, Inc. ("Sit Mutual Funds"), in connection with a special meeting
(the "Meeting") of Regional Fund shareholders to be held at the offices of Sit
Investment Associates, Inc., 4600 Norwest Center, 90 South Seventh Street,
Minneapolis, Minnesota, on _________, 2000, for the purposes set forth in the
accompanying Notice of Special Meeting of Shareholders. This Prospectus/Proxy
Statement is first being mailed to Regional Fund shareholders on or about
__________________, 2000.

         This Prospectus/Proxy Statement relates to a proposed Agreement and
Plan of Reorganization (the "Plan") providing for (i) the acquisition of
substantially all the assets and the assumption of all liabilities of Regional
Fund by Sit Large Cap Growth Fund, Inc. ("Large Cap Fund") in exchange for
shares of common stock of Large Cap Fund having an aggregate net asset value
equal to the aggregate value of the assets acquired (less liabilities assumed)
of Regional Fund, and (ii) the liquidation of Regional Fund and the pro rata
distribution of its holdings of Large Cap Fund shares to Regional Fund
shareholders. As a result of the acquisition, each Regional Fund shareholder
will receive Large Cap Fund shares with a net asset value equal to the net asset
value of their Regional Fund shares.

         Both Regional Fund and Large Cap Fund are diversified, open-end funds
with investment objectives of maximizing long-term capital appreciation. The
Funds' investment objectives, principal investment strategies and principal
risks are described and compared below under "Information About Regional Fund
and Large Cap Fund - Comparison of Investment Objectives, Principal Investment
Strategies and Principal Risks."

         Because Regional Fund shareholders are being asked to approve a
transaction that will result in their receiving shares of Large Cap Fund, this
document also serves as a Prospectus for Large Cap Fund shares. This
Prospectus/Proxy Statement concisely sets forth information about Large Cap Fund
that shareholders of Regional Fund should know before voting on the Plan, and it
should be retained for future reference.

      THESE SECURITIES OR PASSED UPON THE ADEQUACY OF THIS PROSPECTUS. ANY
              REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

FEES AND EXPENSES

         The following table shows the fees and expenses that:

         o        you currently bear as a Regional Fund shareholder (under the
                  "Regional Fund" column);

         o        shareholders of Large Cap Fund currently bear (under the
                  "Large Cap Fund" column); and

         o        you can expect to bear as a Large Cap Fund shareholder after
                  the proposed reorganization (under the "Pro Forma" column).

Both Funds are no-load investments, so you will NOT pay any shareholder fees
such as sales loads, redemption fees or exchange fees when you buy or sell
shares of the Funds. However, when you hold shares of either Fund, you
indirectly pay a portion of that Fund's operating expenses. These expenses are
deducted from Fund assets.

*  Does not reflect the Adviser's waiver of fees for Regional Fund. As a result
   of fee waivers, actual management fees and total annual operating expenses
   for Regional Fund were 1.00% of average daily net assets for the fiscal year
   ended June 30, 1999. After December 31, 2000, fee waivers may be terminated
   at any time by the Adviser.

                                     SUMMARY

         This summary is qualified by reference to the more complete information
contained elsewhere in this Prospectus/Proxy Statement and in the documents
incorporated into this Prospectus/Proxy Statement, and by reference to the Plan,
a copy of which is attached to this Prospectus/Proxy Statement as Exhibit A.
Regional Fund shareholders should review the accompanying documents carefully in
connection with their review of this Prospectus/Proxy Statement.

PROPOSED REORGANIZATION

         The Plan provides for (i) the acquisition of substantially all of the
assets and the assumption of all liabilities of Regional Fund by Large Cap Fund
in exchange for shares of common stock of Large Cap Fund having an aggregate net
asset value equal to the aggregate value of the assets acquired (less
liabilities assumed) of Regional Fund and (ii) the liquidation of Regional Fund
and the pro rata distribution of its holdings of Large Cap Fund shares

                                        3

<PAGE>



to Regional Fund shareholders as of the effective time of the Reorganization
(the "Effective Time"). As a result of the Reorganization, each shareholder of
Regional Fund will receive Large Cap Fund shares with an aggregate net asset
value equal to the aggregate net asset value of the shareholder's Regional Fund
shares as of the Effective Time. See "Information About the Reorganization."

         For the reasons set forth below under "Information About the
Reorganization -- Reasons for the Reorganization," the Board of Directors of Sit
Mutual Funds, including all of the "non-interested" directors, as that term is
defined in the Investment Company Act of 1940, as amended (the "Investment
Company Act"), has concluded that the Reorganization would be in the best
interests of the shareholders of Regional Fund and that the interests of
Regional Fund's existing shareholders would not be diluted as a result of the
transactions contemplated by the Reorganization. Therefore, the Board of
Directors has approved the Reorganization and has submitted the Plan for
approval by Regional Fund shareholders.

         The Board of Directors of Large Cap Fund also has concluded that the
Reorganization would be in the best interests of Large Cap Fund's existing
shareholders and has therefore approved the Reorganization on behalf of Large
Cap Fund.

         Approval of the Plan will require the affirmative vote of a majority of
the outstanding shares of Regional Fund.

TAX CONSEQUENCES

         Prior to completion of the Reorganization, Regional Fund will have
received from counsel an opinion that, upon the Reorganization, no gain or loss
will be recognized by Regional Fund or its shareholders for federal income tax
purposes. The holding period and aggregate tax basis of Large Cap Fund shares
that are received by each Regional Fund shareholder will be the same as the
holding period and aggregate tax basis of Regional Fund shares previously held
by those shareholders. In addition, the holding period and tax basis of the
assets of Regional Fund in the hands of Large Cap Fund as a result of the
Reorganization will be the same as in the hands of Regional Fund immediately
prior to the Reorganization. See "Information About the Reorganization --
Federal Income Tax Consequences."

INVESTMENT OBJECTIVES AND PRINCIPAL INVESTMENT STRATEGIES

         Regional Fund and Large Cap Fund are both diversified, open-end funds
with an investment objective of maximizing long-term capital appreciation. Both
Funds invest primarily in common stocks of growth-oriented companies that the
Adviser believes exhibit the potential for superior growth. However, the Funds'
investment strategies differ in other respects.

         Regional Fund invests at least 80% of its total assets in common stocks
of companies with their headquarters in a midwest region comprised of Minnesota,
Iowa, Missouri, North Dakota, South Dakota, Nebraska, Kansas, Wisconsin,
Illinois, Michigan, Indiana and Ohio. Regional Fund's investments include stocks
of small, mid and large cap companies. Large Cap Fund invests at least 65% of
its total assets in the common stocks of domestic growth companies with
capitalizations of $5 billion or more at the time of purchase. Large Cap Fund
has no geographic restrictions on the companies in which it investments.

FEES AND EXPENSES

         Each Fund is a party to a separate Investment Management Agreement with
the Adviser under which the Adviser manages the Fund's business and investment
activities, subject to the authority of the board of directors. The Agreements
require the Adviser to bear each Fund's expenses except interest, brokerage
commissions and transaction charges and certain extraordinary expenses. The
investment advisory fees for the two Funds, calculated as a percentage of Fund
net assets, are 1.00% for Large Cap Fund and 1.25% for Regional Fund. Thus, if
the Reorganization is approved, shareholders will experience lower contractual
advisory fees as shareholders of Large Cap Fund. See "Fees and Expenses," above.
For the fiscal year ended June 30, 1999, the Adviser waived a portion of its fee
for Regional Fund, resulting in advisory fees equal to 1.00% of average daily
net assets for the fiscal year.

                                        4

<PAGE>



However, the Adviser may discontinue voluntary waivers for Regional Fund at any
time after December 31, 2000, in its sole discretion.

PURCHASE, EXCHANGE AND REDEMPTION PROCEDURES

         Shares of Large Cap Fund received by Regional Fund shareholders in the
Reorganization will be subject to the same purchase, exchange and redemption
procedures that currently apply to Regional Fund shares. These procedures are
discussed in the accompanying prospectus of Large Cap Fund and Regional Fund
under the caption "Shareholder Information."

DIVIDENDS AND DISTRIBUTIONS

         Each Fund distributes an annual dividend from its net investment
income. Capital gains, if any, are distributed at least once a year by each
Fund. Dividend and capital gain distributions are automatically reinvested in
additional shares of the Fund paying the distribution at the net asset value per
share on the distribution date. However, for each Fund, shareholders may request
that distributions be automatically reinvested in another Sit Mutual Fund, or
paid in cash.

                                  RISK FACTORS

         Because each Fund invests primarily in common stocks, the risks of the
two Funds are similar. Principal risks that apply to both Funds are "stock
market risk" and "management risk." Because of its differing investment
strategies, Regional Fund is also subject to "smaller company risk" and "risk of
geographic limitation." Each of these risks is discussed below. All investments
carry some degree of risk which will affect the value of each Fund's investments
and investment performance and the price of its shares. IT IS POSSIBLE TO LOSE
MONEY BY INVESTING IN EITHER FUND.

         Each Fund is subject to the following risks:

         o        STOCK MARKET RISK: The value of the stocks in which a Fund
                  invests may go up or down in response to the activities of
                  individual companies, the stock market and general economic
                  conditions. Stock prices may decline over short or extended
                  periods. As of the date of this Prospectus/Proxy Statement,
                  U.S. stock markets and certain foreign markets are trading at
                  or close to record high levels. There is no guarantee that
                  such levels will continue.

         o        MANAGEMENT RISK: A strategy used by the investment team may
                  not produce the intended results.

         Regional Fund is subject to the following additional risks:

         o        SMALLER COMPANY RISK: Stocks of smaller companies may be
                  subject to more abrupt or erratic market movements than stocks
                  of larger, more established companies. Small companies may
                  have limited product lines or financial resources, or may be
                  dependent upon a small or inexperienced management group. In
                  addition, small cap stocks typically are traded in lower
                  volume, and their issuers typically are subject to greater
                  degrees of change in their earnings and prospects.

         o        RISK OF GEOGRAPHIC LIMITATION: Regional Fund's policy of
                  investing primarily in a midwest geographic region means that
                  the Fund will be subject to adverse economic, political or
                  other developments in that region. The region in which the
                  Fund principally invests has a diverse industrial base
                  (including agriculture, mining, retail, transportation,
                  utilities, heavy and light manufacturing, financial services,
                  insurance, computer technology and medical technology);
                  however, this industrial base is not as diverse as that of the
                  country as a whole. Regional Fund therefore may be less
                  diversified by industry and company than other funds with a
                  similar investment objective and no geographic limitation, and
                  its value may be more susceptible to adverse developments in
                  that region than a more diversified fund.

         The investment securities and techniques of the Funds, and the risks
associated therewith, are described in more detail in the Statement of
Additional Information of the Funds.

                      INFORMATION ABOUT THE REORGANIZATION

REASONS FOR THE REORGANIZATION

         The Boards of Directors of both Regional Fund and Large Cap Fund,
including all of the "non-interested" directors, have determined that it is
advantageous to the respective Funds to combine Regional Fund with Large Cap
Fund. As discussed in detail below under "Information About Regional Fund and
Large Cap Fund," the Funds have identical investment objectives and similar
investment strategies. The Funds also have the same investment adviser (with the
same team of individuals managing both Funds) and the same distributor,
auditors, legal counsel, custodian and transfer agent.

         Each Fund's Board of Directors has determined that the Reorganization
is expected to provide certain benefits to its Fund and is in the best interests
of that Fund and its shareholders. Each Board of Directors has also determined
that the interests of the existing shareholders of its Fund will not be diluted
as a result of the Reorganization. The Boards considered, among other things,
the following factors in making such determinations:

         o        The assessment of the Adviser that Regional Fund is unlikely
                  to grow to a size which is economically viable. The Board
                  considered the Adviser's assertion that the small size of the
                  Fund makes portfolio management difficult. The Fund cannot
                  maintain the level of investment diversification that the
                  Adviser desires, and the Fund's smaller size results in
                  increased transaction costs which reduce the return to
                  shareholders. As a much larger fund, Large Cap Fund is able to
                  achieve greater investment diversification and generally has
                  lower transaction costs.

         o        The Fund's midwestern geographic focus precludes the Fund from
                  taking advantage of a number of investment opportunities
                  available in other areas of the country. Large Cap Fund is not
                  subject to any geographic limitations on its investments.

         o        Regional Fund shareholders will experience a lower contractual
                  management fee as a result of the Reorganization and, because
                  the Adviser bears all Fund expenses (except interest,
                  brokerage commissions and transaction charges and certain
                  extraordinary expenses), lower total Fund operating expenses.

         o        The proposed Reorganization will be tax-free.

         o        The terms and conditions of the Plan, including that the
                  exchange of Regional Fund shares for Large Cap Fund shares
                  will take place on a net asset value basis and that expenses
                  of the Reorganization will be borne by the Adviser.

         The Boards concluded that the factors noted above render the proposed
Reorganization fair to and in the best interests of shareholders of Regional
Fund and Large Cap Fund.

PLAN OF REORGANIZATION

         The following summary of the proposed Plan and the Reorganization is
qualified in its entirety by reference to the Plan attached to this
Prospectus/Proxy Statement as Exhibit A. The Plan provides that, as of the
Effective Time, Large Cap Fund will acquire all or substantially all of the
assets and assume all liabilities of Regional Fund in exchange for Large Cap
Fund shares having an aggregate net asset value equal to the aggregate value of
the assets acquired (less liabilities assumed) from Regional Fund. For corporate
law purposes the transaction is structured as a sale of the assets and
assumption of the liabilities of Regional Fund in exchange for the issuance of
Large Cap Fund shares to Regional Fund, followed immediately by the distribution
of such Large Cap Fund shares to Regional Fund shareholders and the cancellation
and retirement of outstanding Regional Fund shares. This reallocation of assets
and liabilities and exchange of shares is accomplished under the Plan by

                                        6

<PAGE>


amending the articles of incorporation of Sit Mutual Funds in the manner set
forth in the amendment to Sit Mutual Funds' articles of incorporation included
as Exhibit 1 to the Plan attached hereto as Exhibit A.

         Under the Plan, each holder of Regional Fund shares will receive, at
the Effective Time, Large Cap Fund shares with an aggregate net asset value
equal to the aggregate net asset value of Regional Fund shares owned by that
shareholder immediately prior to the Effective Time. The net asset value per
share of each Fund's shares will be computed as of the Effective Time using the
valuation procedures set forth in the respective Funds' articles of
incorporation and bylaws and then-current Prospectus and Statement of Additional
Information and as may be required by the Investment Company Act.

         At the Effective Time, Large Cap Fund will issue to Regional Fund, and
Regional Fund will distribute to Regional Fund's shareholders of record,
determined as of the Effective Time, the Large Cap Fund shares issued in
exchange for Regional Fund assets as described above. All outstanding shares of
Regional Fund will then be canceled and retired and no additional shares
representing interests in Regional Fund will be issued thereafter, and Regional
Fund will be deemed to be liquidated. The distribution of Large Cap Fund shares
to former Regional Fund shareholders will be accomplished by the establishment
of accounts on the share records of Large Cap Fund in the names of Regional Fund
shareholders, each representing the numbers of full and fractional Large Cap
Fund shares due such shareholders.

         Regional Fund contemplates that it will make a distribution,
immediately prior to the Effective Time, of all of its current year net income
and net realized capital gains, if any, not previously distributed. This
distribution will be taxable to Regional Fund shareholders subject to taxation.

         The consummation of the Reorganization is subject to the conditions set
forth in the Plan, including, among others:

         o        approval of the Plan by the shareholders of Regional Fund;

         o        the delivery of the opinion of counsel described below under
                  "--Federal Income Tax Consequences;"

         o        the accuracy as of the Effective Time of the representations
                  and warranties made by Regional Fund and Large Cap Fund in the
                  Plan; and

         o        the delivery of customary closing certificates.

See the Plan attached to this Prospectus/Proxy Statement as Exhibit A for a
complete listing of the conditions to the consummation of the Reorganization.
The Plan may be terminated and the Reorganization abandoned at any time prior to
the Effective Time, before or after approval by shareholders of Regional Fund,
by resolution of the Board of Directors of either Regional Fund or Large Cap
Fund, if circumstances should develop that, in the opinion of that Board, make
proceeding with the consummation of the Plan and Reorganization not in the best
interests of the respective Fund's shareholders.

         The Plan provides that all expenses incurred in connection with the
Reorganization will be borne by the Adviser.

         Approval of the Plan will require the affirmative vote of a majority of
the outstanding shares of Regional Fund. If the Plan is not approved, the Boards
of Directors of the respective Funds will consider other possible courses of
action. Regional Fund shareholders are not entitled to assert dissenters' rights
of appraisal in connection with the Plan or Reorganization. See "Voting
Information -- No Dissenters' Rights of Appraisal" below.

DESCRIPTION OF LARGE CAP FUND AND REGIONAL FUND SHARES

         Sit Mutual Funds offers its shares in a number of separate series, one
of which is Regional Fund. Each share of a series has one vote (with
proportionate voting for fractional shares) irrespective of the relative net
assets values of the series' shares. On some issues, such as the election of
directors, all shares of Sit Mutual Funds vote together as one series. On an
issue affecting only a particular series, such as the Reorganization, the shares
of the affected series vote separately. Large Cap Fund offers a single series of
shares, each of which has one vote, with

                                        7

<PAGE>



proportionate voting for fractional shares. All Large Cap Fund shares issued in
the Reorganization will be fully paid and non-assessable and will not be
entitled to pre-emptive or cumulative voting rights.

FEDERAL INCOME TAX CONSEQUENCES

         It is intended that the exchange of Large Cap Fund shares for Regional
Fund's net assets and the distribution of those shares to Regional Fund's
shareholders upon liquidation of Regional Fund will be treated as a tax-free
reorganization under the Internal Revenue Code of 1986, as amended (the "Code"),
and that, for federal income tax purposes, no income, gain or loss will be
recognized by Regional Fund's shareholders (except that Regional Fund
contemplates that it will make a distribution, immediately prior to the
Effective Time, of all of its current year net income and net realized capital
gains, if any, not previously distributed, and this distribution will be taxable
to Regional Fund shareholders subject to taxation). Regional Fund has not asked,
nor does it plan to ask, the Internal Revenue Service to rule on the tax
consequences of the Reorganization.

         As a condition to the closing of the Reorganization, the two Funds will
receive an opinion from Dorsey & Whitney LLP, counsel to the Funds, based in
part on certain representations to be furnished by each Fund, substantially to
the effect that the federal income tax consequences of the Reorganization will
be as follows:

         o        the Reorganization will constitute a reorganization within the
                  meaning of Section 368(a)(1)(C) of the Code, and Large Cap
                  Fund and Regional Fund each will qualify as a party to the
                  Reorganization under Section 368(b) of the Code;

         o        Regional Fund shareholders will recognize no income, gain or
                  loss upon receipt, pursuant to the Reorganization, of Large
                  Cap Fund shares. Regional Fund shareholders subject to
                  taxation will recognize income upon receipt of any net
                  investment income or net capital gains of Regional Fund which
                  are distributed by Regional Fund prior to the Effective Time;

         o        the tax basis of the Large Cap Fund shares received by each
                  Regional Fund shareholder pursuant to the Reorganization will
                  be equal to the tax basis of Regional Fund shares exchanged
                  therefor;

         o        the holding period of the Large Cap Fund shares received by
                  each Regional Fund shareholder pursuant to the Reorganization
                  will include the period during which the Regional Fund
                  shareholder held the Regional Fund shares exchanged therefor,
                  provided that the Regional Fund shares were held as a capital
                  asset at the Effective Time;

         o        Regional Fund will recognize no income, gain or loss by reason
                  of the Reorganization;

         o        Large Cap Fund will recognize no income, gain or loss by
                  reason of the Reorganization;

         o        the tax basis of the assets received by Large Cap Fund
                  pursuant to the Reorganization will be the same as the basis
                  of those assets in the hands of Regional Fund as of the
                  Effective Time;

         o        the holding period of the assets received by Large Cap Fund
                  pursuant to the Reorganization will include the period during
                  which such assets were held by Regional Fund; and

         o        Large Cap Fund will succeed to and take into account the
                  earnings and profits, or deficit in earnings and profits, of
                  Regional Fund as of the Effective Time.

         Shareholders of Regional Fund should consult their tax advisors
regarding the effect, if any, of the proposed Reorganization in light of their
individual circumstances. Since the foregoing discussion only relates to the
federal income tax consequences of the Reorganization, shareholders of Regional
Fund should consult their tax advisors as to state and local tax consequences,
if any, of the Reorganization.

COMPARISON OF INVESTMENT OBJECTIVES AND PRINCIPAL INVESTMENT STRATEGIES

         The investment objective of each Fund is to maximize long-term capital
appreciation. The principal investment strategies that the Funds use to achieve
this objective differ in a number of respects.

         Large Cap Fund seeks to achieve its objective by investing at least 65%
of its total assets in the common stocks of domestic growth companies with
capitalizations of $5 billion or more at the time of purchase.

         Regional Fund seeks to achieve its objective by investing at least 80%
of its total assets in common stocks of companies with their headquarters in a
midwest region comprised of Minnesota, Iowa, Missouri, North Dakota, South
Dakota, Nebraska, Kansas, Wisconsin, Illinois, Michigan, Indiana and Ohio. The
Fund's investments will include stocks of small, mid and large cap companies.
Because of its geographic limitation and its ability to invest in stocks of
smaller companies, Regional Fund is subject to additional risks when compared to
Large Cap Fund. See "Risk Factors."

         For each Fund, the Adviser invests in growth-oriented companies that it
believes exhibit the potential for superior growth. The Adviser believes that a
company's earning growth is the primary determinant of its potential long-term
return and evaluates a company's potential for above average long-term earnings
and revenue growth. Several factors are considered in the Adviser's evaluation
of a company, including:

        o         unique product or service,
        o         growing product demand,
        o         dominant and growing market share,
        o         management experience and capabilities, and
        o         strong financial condition.

When selling equity securities for either Fund, the Adviser considers several
factors, including changes in a company's fundamentals and anticipated earnings.

                               VOTING INFORMATION

GENERAL

         This Prospectus/Proxy Statement is furnished in connection with a
solicitation of proxies by the Board of Directors of Regional Fund to be used at
the Special Meeting of Regional Fund shareholders to be held at ____ a.m.,
Central time, on _______________, 2000, at the offices of the Adviser, 4600
Norwest Center, 90 South Seventh Street, Minneapolis, Minnesota and at any
adjournments thereof. Only shareholders of record as of the close of business on
_________________, 2000 (the "Record Date") will be entitled to notice of, and
to vote at, the Meeting or any adjournment thereof. If the enclosed form of
proxy is properly executed and returned on time to be voted at the Meeting, the
proxies named in the form of proxy will vote the shares represented by the proxy
in accordance with the instructions marked thereon. Unmarked proxies will be
voted "for" the proposed Plan and Reorganization. A proxy may be revoked by
giving written notice, in person or by mail, of revocation before the Meeting to
Regional Fund at its principal executive offices, 4600 Norwest Center, 90 South
Seventh Street, Minneapolis, Minnesota, or by properly executing and submitting
a later-dated proxy, or by voting in person at the Meeting.

         If a shareholder executes and returns a proxy but abstains from voting,
the shares held by that shareholder will be deemed present at the Meeting for
purposes of determining a quorum and will be included in determining the total
number of votes cast. If a proxy is received from a broker or nominee indicating
that such person has not received instructions from the beneficial owner or
other person entitled to vote Regional Fund shares (i.e., a broker "non-vote"),
the shares represented by that proxy will not be considered present at the
Meeting for purposes of determining a quorum and will not be included in
determining the number of votes cast. Brokers and nominees will not have
discretionary authority to vote shares for which instructions are not received
from the beneficial owner.

         Approval of the Plan and Reorganization will require the affirmative
vote described above under "Information About the Reorganization --
Recommendation and Vote Required."

         As of ________________, 2000, Regional Fund had ____ shares outstanding
and entitled to vote at the Meeting. As of that date, the directors and officers
of Large Cap Fund as a group owned less than one percent of the outstanding
shares of such Fund, and the Fund knew of no person or entity which owned of
record or beneficially more than 5% of the Fund's outstanding shares. The
following table sets forth, as of that date, (i) share ownership of individual
directors and officers who own of record or beneficially more than one percent
of the outstanding shares of Regional Fund; (ii) share ownership of all
directors and officers as a group; and (iii) share ownership of those persons
known by Regional Fund to own of record or beneficially more than 5% of the
outstanding shares of such, including persons and entities who beneficially own
more than 25% of either Fund. The persons named below have both record and
beneficial ownership, and their address is 4600 Norwest Center, 90 South Seventh
Street, Minneapolis, Minnesota 55402:

Reorganization are not received by the date set for the Meeting, the persons
named as proxies may propose one or more adjournments of the Meeting for up to
120 days to permit further solicitation of proxies. In determining whether to
adjourn the Meeting, the following factors may be considered: the percentage of

of any further solicitation and the information to be provided to shareholders
with respect to the reasons for the solicitation. Any such adjournment will
require the affirmative vote of a majority of the shares present in person or by
proxy and entitled to vote at the Meeting. The persons named as proxies will
vote upon such adjournment after consideration of the best interests of all
shareholders.

AGREEMENT AND PLAN OF REORGANIZATION

          SIT REGIONAL GROWTH FUND AND SIT LARGE CAP GROWTH FUND, INC.

         THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made as
of this ____ day of _______, 2000, by and between Sit Mutual Funds, Inc. ("Sit
Funds"), a Minnesota corporation, on behalf of its series Sit Regional Growth
Fund ("Regional Fund"), and Sit Large Cap Growth Fund, Inc. ("Large Cap Fund"),
a Minnesota corporation. As used in this Agreement, the term "Regional Fund"
shall be construed to mean "Sit Funds on behalf of Regional Fund" where
necessary to reflect the fact that a corporate series is generally considered
the beneficiary of corporate level actions taken with respect to the series and
is not itself recognized as a person under law. The shares of Regional Fund are
designated in the amended and restated articles of incorporation of Sit Funds as
the Series F shares of Sit Funds.

         This Agreement is intended to be and is adopted as a plan of
reorganization and liquidation pursuant to Sections 368(a)(1)(C) and
368(a)(2)(G) of the United States Internal Revenue Code of 1986, as amended (the
"Code"). The reorganization (the "Reorganization") will consist of the transfer
of all or substantially all of the assets of Regional Fund to Large Cap Fund and
the assumption by Large Cap Fund of all of the liabilities of Regional Fund in
exchange solely for full and fractional shares of common stock, par value $.01
per share, of Large Cap Fund (the "Large Cap Fund Shares"), having an aggregate
net asset value equal to the aggregate value of the assets acquired (less
liabilities assumed) of Regional Fund, and the distribution of Large Cap Fund
Shares to the shareholders of Regional Fund in liquidation of Regional Fund as
provided herein, all upon the terms and conditions hereinafter set forth. The
distribution of Large Cap Fund Shares to Regional Fund shareholders and the
retirement and cancellation of Regional Fund shares will be effected pursuant to
an amendment to the Articles of Incorporation of Sit Funds in the form attached
hereto as Exhibit 1 (the "Amendment"), to be adopted by Sit Funds in accordance
with the Minnesota Business Corporation Act.

         WITNESSETH:

         WHEREAS, each of Sit Funds and Large Cap Fund is a registered, open-end
management investment company, with Sit Funds offering its shares of common
stock in multiple series (each of which series represents a separate and
distinct portfolio of assets and liabilities), one of those series being
Regional Fund, and Large Cap Fund offering its shares of common stock in a
single series;

         WHEREAS, Regional Fund owns securities which generally are assets of
the character in which Large Cap Fund is permitted to invest; and

         WHEREAS, the Board of Directors of each of Sit Funds and Large Cap Fund
has determined that the exchange of all or substantially all of the assets of
Regional Fund for Large Cap Fund Shares and the assumption of all of the
liabilities of Regional Fund by Large Cap Fund is in the best interests of the
shareholders of Regional Fund and Large Cap Fund, respectively.

         NOW, THEREFORE, in consideration of the premises and of the
representations, warranties, covenants and agreements hereinafter set forth, the
parties hereto covenant and agree as follows:

1.       TRANSFER OF ALL OR SUBSTANTIALLY ALL OF THE ASSETS OF REGIONAL FUND TO
         LARGE CAP FUND SOLELY IN EXCHANGE FOR LARGE CAP FUND SHARES, THE
         ASSUMPTION OF ALL REGIONAL FUND LIABILITIES AND THE LIQUIDATION OF
         REGIONAL FUND

         1.1 Subject to the requisite approval by Regional Fund shareholders and
to the other terms and conditions set forth herein and on the basis of the
representations and warranties contained herein, Regional Fund agrees to
transfer all or substantially all of Regional Fund's assets as set forth in
Section 1.2 to Large Cap Fund, and Large Cap Fund agrees in exchange therefor
(a) to deliver to Regional Fund that number of full and fractional Large Cap



                                       A-1

<PAGE>



Fund Shares determined in accordance with Article 2, and (b) to assume all of
the liabilities of Regional Fund, as set forth in Section 1.3. Such transactions
shall take place as of the effective time provided for in Section 3.1 (the
"Effective Time").

         1.2 (a) The assets of Regional Fund to be acquired by Large Cap Fund
shall consist of all or substantially all of Regional Fund's property,
including, but not limited to, all cash, securities, commodities, futures, and
interest and dividends receivable which are owned by Regional Fund as of the
Effective Time. All of said assets shall be set forth in detail in an unaudited
statement of assets and liabilities of Regional Fund as of the Effective Time
(the "Effective Time Statement"). The Effective Time Statement shall, with
respect to the listing of Regional Fund's portfolio securities, detail the
adjusted tax basis of such securities by lot, the respective holding periods of
such securities and the current and accumulated earnings and profits of Regional
Fund. The Effective Time Statement shall be prepared in accordance with
generally accepted accounting principles (except for footnotes) consistently
applied from the prior audited period.

         (b) Regional Fund has provided Large Cap Fund with a list of all of
Regional Fund's assets as of the date of execution of this Agreement. Regional
Fund reserves the right to sell any of these securities in the ordinary course
of its business and, subject to Section 5.1, to acquire additional securities in
the ordinary course of its business.

         1.3 Large Cap Fund shall assume all of the liabilities, expenses,
costs, charges and reserves (including, but not limited to, expenses incurred in
the ordinary course of Regional Fund's operations, such as accounts payable
relating to custodian fees, investment management and administrative fees, legal
and audit fees, and expenses of state securities registration of Regional Fund's
shares), including those reflected in the Effective Time Statement.

         1.4 Immediately after the transfer of assets provided for in Section
1.1 and the assumption of liabilities provided for in Section 1.3, and pursuant
to the plan of reorganization adopted herein, Regional Fund will distribute pro
rata (as provided in Article 2) to Regional Fund's shareholders of record,
determined as of the Effective Time (the "Regional Fund Shareholders"), the
Large Cap Fund Shares received by Regional Fund pursuant to Section 1.1, and all
other assets of Regional Fund, if any. Thereafter, no additional shares
representing interests in Regional Fund shall be issued. Such distribution will
be accomplished by the transfer of the Large Cap Fund Shares then credited to
the account of Regional Fund on the books of Large Cap Fund to open accounts on
the share records of Large Cap Fund in the names of Regional Fund shareholders
representing the numbers and classes of Large Cap Fund Shares due each such
shareholder. All issued and outstanding shares of Regional Fund will
simultaneously be canceled on the books of Regional Fund, although share
certificates representing interests in Regional Fund will represent those
numbers and classes of Large Cap Fund Shares after the Effective Time as
determined in accordance with Article 2. Unless requested by Regional Fund
Shareholders, Large Cap Fund will not issue certificates representing Large Cap
Fund Shares issued in connection with such exchange.

         1.5 Ownership of Large Cap Fund Shares will be shown on the books of
Large Cap Fund. Large Cap Fund Shares will be issued in the manner described in
Large Cap Fund's Prospectus and Statement of Additional Information as in effect
as of the Effective Time.

         1.6 Any reporting responsibility of Regional Fund, including, but not
limited to, the responsibility for filing of regulatory reports, tax returns, or
other documents with the Securities and Exchange Commission (the "Commission"),
any state securities commissions, and any federal, state or local tax
authorities or any other relevant regulatory authority, is and shall remain the
responsibility of Regional Fund.

2.       VALUATION; ISSUANCE OF LARGE CAP FUND SHARES

         2.1 The net asset value per share of Regional Fund's shares shall be
computed as of the Effective Time using the valuation procedures set forth in
its articles of incorporation and bylaws, its then-current Prospectus and
Statement of Additional Information, and as may be required by the Investment
Company Act of 1940, as amended (the "1940 Act").




                                       A-2

<PAGE>



         2.2 The total number of Large Cap Fund shares to be issued (including
fractional shares, if any) in exchange for the assets and liabilities of
Regional Fund shall be determined as of the Effective Time by multiplying the
number of Regional Fund shares outstanding immediately prior to the Effective
Time by a fraction, the numerator of which is the net asset value per share of
Regional Fund's shares immediately prior to the Effective Time, and the
denominator of which is the net asset value per share of Large Cap Fund's shares
immediately prior to the Effective Time, each as determined pursuant to Section
2.1.

         2.3 Immediately after the Effective Time, Regional Fund shall
distribute to Regional Fund Shareholders in liquidation of Regional Fund pro
rata (based upon the ratio that the number of Regional Fund shares owned by each
Regional Fund Shareholder immediately prior to the Effective Time bears to the
total number of issued and outstanding Regional Fund shares immediately prior to
the Effective Time) the full and fractional Large Cap Fund Shares received by
Regional Fund pursuant to Section 2.2. Accordingly, each Regional Fund
Shareholder shall receive, immediately after the Effective Time, Large Cap Fund
shares with an aggregate net asset value equal to the aggregate net asset value
of the Regional Fund shares owned by such Regional Fund Shareholder immediately
prior to the Effective Time.

3.       EFFECTIVE TIME; CLOSING

         3.1 The closing of the transactions contemplated by this Agreement (the
"Closing") shall occur as of the close of normal trading on the New York Stock
Exchange (the "Exchange") (currently, 4:00 p.m. Eastern time) on the first day
upon which the conditions to closing shall have been satisfied (but not prior to
, 2000), or at such time on such later date as provided herein or as the parties
otherwise may agree in writing (such time and date being referred to herein as
the "Effective Time"). All acts taking place at the Closing shall be deemed to
take place simultaneously as of the Effective Time unless otherwise agreed to by
the parties. The Closing shall be held at the offices of Dorsey & Whitney LLP,
220 South Sixth Street, Minneapolis, Minnesota 55402, or at such other place as
the parties may agree.

         3.2 Regional Fund shall deliver at the Closing its written instructions
to the custodian for Regional Fund, acknowledged and agreed to in writing by
such custodian, irrevocably instructing such custodian to transfer to Large Cap
Fund all of Regional Fund's portfolio securities, cash, and any other assets to
be acquired by Large Cap Fund pursuant to this Agreement.

         3.3 In the event that the Effective Time occurs on a day on which (a)
the Exchange or another primary trading market for portfolio securities of Large
Cap Fund or Regional Fund shall be closed to trading or trading thereon shall be
restricted, or (b) trading or the reporting of trading on the Exchange or
elsewhere shall be disrupted so that accurate appraisal of the value of the net
assets of Large Cap Fund or Regional Fund is impracticable, the Effective Time
shall be postponed until the close of normal trading on the Exchange on the
first business day when trading shall have been fully resumed and reporting
shall have been restored.

         3.4 Regional Fund shall deliver at the Closing its certificate stating
that the records maintained by its transfer agent (which shall be made available
to Large Cap Fund) contain the names and addresses of Regional Fund shareholders
and the number of outstanding Regional Fund shares owned by each such
shareholder as of the Effective Time. Large Cap Fund shall certify at the
Closing that Large Cap Fund Shares required to be issued by it pursuant to this
Agreement have been issued and delivered as required herein.

         3.5 At the Closing, each party to this Agreement shall deliver to the
other such bills of sale, liability assumption agreements, checks, assignments,
share certificates, if any, receipts or other similar documents as such other
party or its counsel may reasonably request.

of Regional Fund, enforceable in accordance with its terms, subject, as to
enforcement, to bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance and other laws relating to or affecting creditors' rights and to the
application of equitable principles in any proceeding, whether at law or in
equity;

         (n) The information to be furnished by and on behalf of Regional Fund

         (o) All information pertaining to Regional Fund, its agents and
affiliates and included in the Registration Statement referred to in Section 5.5
(or supplied by Regional Fund or its agents or affiliates for inclusion in said
Registration Statement), on the effective date of said Registration Statement
and up to and including the Effective Time, will not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which such statements are made, not materially misleading
(other than as may timely be remedied by further appropriate disclosure);

         (p) Since the end of Regional Fund's most recently concluded fiscal

generally accepted accounting principles (except for footnotes) consistently
applied and will present accurately the assets and liabilities of Regional Fund
as of the Effective Time, and the values of Regional Fund's assets and
liabilities to be set forth in the Effective Time Statement will be computed as
of the Effective Time using the valuation procedures set forth in Regional
Fund's articles of incorporation and bylaws, its then-current Prospectus and
Statement of Additional Information, and as may be required by the 1940 Act. At
the Effective Time, Regional Fund will have no liabilities, whether absolute or
contingent, known or unknown, accrued or unaccrued, which are not reflected in
the Effective Time Statement.

                  (b) At the Closing Date, the assets belonging to the Acquired
         Fund, the Special Liabilities associated with such assets, and the
         General Assets and General Liabilities allocated to the Acquired Fund
         shall be sold to and assumed by the Acquiring Fund in return for
         Acquiring Fund shares, all pursuant to the Agreement and Plan of
         Reorganization. For purposes of the foregoing, the terms "Assets
         belonging to," "Special Liabilities," "General Assets" and "General

         Acquired Fund and distributed by it to the Acquired Fund shareholders
         shall be determined as follows:

                           (i) The value of the Acquired Fund's assets and the
                  net asset value per share of the Acquiring Fund's shares shall
                  be computed as of the Valuation Date using the valuation
                  procedures set forth in the Acquiring Fund's then-current
                  Prospectus and Statement of Additional Information, and as may
                  be required by the Investment Company Act of 1940, as amended
                  (the "1940 Act").

                           (ii) The total number of Acquiring Fund shares to be
                  issued (including fractional shares, if any) in exchange for
                  assets and liabilities of the Acquired Fund shall be
                  determined as of the Valuation Date by dividing the value of
                  the Acquired Fund's assets, net of its stated liabilities on
                  the Closing Date to be assumed by the Acquiring Fund, by the
                  net asset value of the Acquiring Fund's shares, each as
                  determined pursuant to (i) above.

                           (iii) On the Closing Date, or as soon as practicable
                  thereafter, the Acquired Fund shall distribute PRO RATA to its
                  shareholders of record as of the Valuation Date the full and
                  fractional Acquiring Fund shares received by the Acquired Fund
                  pursuant to (ii) above.

                  (d) The distribution of Acquiring Fund shares to Acquired Fund
         shareholders provided for in paragraph (c) above shall be accomplished
         by an instruction, signed by Sit Fund's Secretary, to transfer
         Acquiring Fund shares then credited to the Acquired Fund's account on
         the books of the Acquiring Fund to open accounts on the books of the
         Acquiring Fund in the names of the Acquired Fund shareholders in
         amounts representing the respective PRO RATA number of Acquiring Fund
         shares due each such shareholder pursuant to the foregoing provisions.
         All issued and outstanding shares of the Acquired Fund shall
         simultaneously be canceled on the books of the Acquired Fund and
         retired.

                  (e) From and after the Closing Date, the Acquired Fund shares
         canceled and retired pursuant to paragraph (d) above shall have the
         status of authorized and unissued Shares of Sit Fund, without
         designation as to series.

         IN WITNESS WHEREOF, the undersigned officer of Sit Funds has executed
these Articles of Amendment on behalf of Sit Funds on __________, 2000.

FUND SUMMARIES
- --------------------------------------------------------------------------------

BALANCED FUND

INVESTMENT OBJECTIVE

The Fund seeks long-term capital growth consistent with preservation of
principal and to provide shareholders with regular income.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its objective by investing in a diversified portfolio
of stocks, bonds, and short-term instruments. In seeking to achieve the Fund's
long-term capital growth objective, the Fund invests in common stocks of growth
companies. The Fund balances its long-term growth objective by investing in
income-producing debt securities and/or common stocks selected primarily for
their dividend payment potential.

During normal market conditions, between 40% and 60% of the Fund's assets will
be invested in equity securities and between 40% and 60% in fixed-income
securities. The Fund's allocation of assets will vary over time in response to
the Adviser's evaluation of present and anticipated market and economic
conditions.

                        [*Sidebar:] The Fund combines the investment strategies
                        of the Large Cap Growth Fund and the Bond Fund.

The equity portion of the Fund's portfolio is invested primarily in the common
stocks of growth companies with a capitalization of $5 billion or more at the
time of purchase. The Adviser utilizes the same investment strategies for the
Fund that it uses for the Large Cap Growth Fund in selecting equity securities.

<PAGE>


The Fund may invest up to 20% of its assets in foreign government securities or
equity securities of foreign issuers that are either listed on a U.S. or Toronto
stock exchange or represented by American Depository Receipts.

The fixed income portion of the Fund's portfolio is invested primarily in a
diversified portfolio of debt securities that may include the following
securities. The Adviser utilizes the same investment strategies for the Fund
that it uses for the Sit Bond Fund in selecting the fixed-income securities.
- -     mortgage-backed securities, such as securities issued by Government
      National Mortgage Association (GNMA), Federal Home Loan Mortgage
      Corporation (FHLMC) and Federal National Mortgage Association (FNMA), and
      including collateralized mortgage obligations,
- -     asset-backed securities such as automobile and credit card receivables,
      utilities, manufactured (mobile) home loans, home improvement loans and
      home equity loans,
- -     obligations of the U.S. government, its agencies and instrumentalities,
- -     corporate debt securities,
- -     taxable municipal securities, and
- -     short-term debt obligations, including commercial paper and bank
      instruments, such as certificates of deposit, time deposits, and bankers'
      acceptances.

The Fund invests primarily in debt securities that, at the time of purchase, are
either rated investment-grade or if unrated, determined to be of comparable
quality by the Adviser. Unrated securities will not exceed 20% of the Fund's
total assets.

In selecting fixed-income securities for the Fund, the Adviser seeks
fixed-income securities providing maximum total return. In making purchase and
sales decisions for the Fund, the Adviser considers its economic outlook and
interest rate forecast, as well as its evaluation of a fixed-income security's
credit quality, yield, maturity, and liquidity. Based upon its economic outlook,
the Adviser attempts to shift the fixed-income sector concentrations of the
portfolio. Based upon its interest rate forecast, the Adviser attempts to shift
the fixed-income portfolio's average effective duration, seeking to maintain an
average effective duration for the fixed-income portion of the Fund's portfolio
of 3 to 7 years.

LARGE CAP GROWTH FUND

INVESTMENT OBJECTIVE

The Fund seeks to maximize long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its objective by investing at least 65% of its total
assets in the common stocks of growth companies with capitalizations of $5

                        market capitalization of $5 billion or more.

The Adviser invests in growth-oriented companies it believes exhibit the
potential to increase earnings at a faster rate than the economy and respective
market index. The Adviser believes that a company's earnings growth is the
primary determinant of its potential long-term return and considers several
factors in its evaluation of a company, including:
- -     potential for above average long-term earnings and revenue growth,
- -     unique product or service,
- -     growing product demand,
- -     dominant and growing market share,
- -     management experience and capabilities, and

<PAGE>


- -     strong financial strategy.

                        issued by companies with records of stable profit growth
                        and dividend payments.

equity securities of foreign issues that are either listed on a U.S. or Toronto
stock exchange or represented by American Depository Receipts.

The Adviser invests in a diversified group of growing medium to small companies
it believes exhibit the potential to increase earnings at a faster rate than the
economy and respective market index. The Adviser believes that a company's
earnings growth is the primary determinant of its potential long-term return and
considers several factors in its evaluation of a company, including:
- -     potential for above average long-term earnings and revenue growth,
- -     unique product or service,
- -     growing product demand,

<PAGE>


- -     dominant and growing market share,
- -     management experience and capabilities, and
- -     strong financial strategy.

The Fund may invest up to 20% of its assets in foreign government securities or
equity securities of foreign issues that are either listed on a U.S. or Toronto
stock exchange or represented by American Depository Receipts.

INTERNATIONAL GROWTH FUND

INVESTMENT OBJECTIVE

The Fund seeks long-term growth.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its objective by investing at least 90% of its total
assets, under normal market conditions, in common stocks of issuers domiciled in
at least three foreign countries.

In selecting investments for the Fund, the Sub-Adviser begins by selecting
countries or regions in which to invest. In making its selections, the
Sub-Adviser considers several factors affecting the economy and equity market of
foreign countries and regions, including:
- -     economic trends,
- -     earnings outlook,
- -     liquidity within the market,
- -     fiscal and monetary policy,
- -     currency exchange rate expectations,
- -     investment valuation,
- -     market sentiment, and
- -     social and political trends.

The Sub-Adviser believes that favorable secular trends can provide significant
investment opportunities, and therefore, after the country and regional
allocations are determined, the Sub-Adviser seeks industries and sectors that it
believes have strong earnings growth prospects. Within the selected industries
and sectors, the Sub-Adviser invests in foreign growth-oriented companies it
believes exhibit the potential to increase earnings at a faster rate than the
respective economy and market index. The Sub-Adviser believes that a company's
earnings growth is the primary determinant of its potential long-term return and
considers several factors in its evaluation of a company, including:
- -     potential for above average long-term earnings and revenue growth,
- -     unique product or service,
- -     growing product demand,
- -     dominant and growing market share,
- -     management experience and capabilities, and
- -     strong financial strategy.

Up to 50% of the Fund's total assets may be invested in equity securities of
smaller to medium sized emerging growth companies in developed markets (such as
Germany and Japan) and developing markets (such as Thailand and Brazil).
Emerging growth companies are small- and medium-sized companies that the
Sub-Adviser believes have a potential for earnings growth over time that is
above the growth rate of more established companies or are early in their life
cycles and have the potential to become major enterprises.

The Fund may invest in securities representing underlying international
securities such as American Depository Receipts, European Depository Receipts
and Global Depository Receipts.

In order to hedge against adverse movements in currency exchange rates, the Fund
may from time to time enter into forward foreign currency exchange contracts.

SMALL CAP GROWTH FUND

INVESTMENT OBJECTIVE

The Fund seeks to maximize long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its objective by investing at least 65% of its total
assets, under normal market conditions, in common stocks of small growth
companies with capitalizations of $2.5 billion or less at the time of purchase.

                        [*Sidebar:] The Fund invests in companies having a
                        market capitalization of $2.5 billion or less.

SCIENCE AND TECHNOLOGY GROWTH FUND

INVESTMENT OBJECTIVE

The Fund seeks to maximize long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its objective by investing at least 80% of its total
assets, under normal market conditions, in common stocks of companies which the
Adviser expects to benefit from the development, improvement, advancement and
use of science and technology. The Fund's investments will include stocks of
smaller companies.

Science and technology companies include those whose processes, products or
services, in the judgment of the Adviser, are significantly benefiting, or may
be expected to significantly benefit, from scientific developments and the
application of technical advances in industry, manufacturing and commerce
resulting from improving technology in these fields. The Adviser seeks stocks of
science and technology companies having superior growth potential in virtually
any industry in which they may be found. Such industries may include:
- -     aerospace,
- -     chemistry,
- -     electronic components and systems,
- -     environmental services,

<PAGE>


- -     genetic engineering,
- -     geology,
- -     information sciences (including computers, software and peripheral
      products),
- -     medicine (including pharmacology, biotechnology and biophysics), and
- -     hospital supply and medical devices.

The Adviser invests in growth-oriented companies it believes exhibit the
potential to increase earnings at a faster rate than the respective economy and
market index. The Adviser believes that a company's earnings growth is the
primary determinant of its potential long-term return and considers several
factors in its evaluation of a company, including:

equity securities of foreign issuers that are either listed on a U.S. or Toronto
stock exchange or represented by American Depository Receipts.

DEVELOPING MARKETS GROWTH FUND

INVESTMENT OBJECTIVE

The Fund seeks to maximize long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its objective by investing at least 65% of its total
assets, under normal market conditions, in common stocks of companies domiciled
or operating in a developing market.

Developing markets are those countries that:
- -     have emerging stock markets as defined by the International Finance
      Corporation,
- -     have low- to middle-income economies according to the World Bank, or
- -     are listed in World Bank publications as "developing."

In selecting investments for the Fund, the Sub-Adviser begin by selecting
countries or regions in which to invest. In making its selections, the
Sub-Adviser considers several factors affecting the economy and equity market of
foreign countries and regions, including:
- -     economic trends,
- -     earnings outlook,
- -     liquidity within the market,
- -     fiscal and monetary policy,
- -     currency exchange rate expectations,
- -     investment valuation,
- -     market sentiment, and
- -     social and political trends.

The Sub-Adviser believes that favorable secular trends can provide significant
investment opportunities, and therefore, after the country and regional
allocations are determined, the Sub-Adviser seeks industries and sectors that
have strong earnings growth prospects. Within the selected industries and
sectors, the Sub-Adviser invests in foreign growth-oriented companies it

economy and market index. The Sub-Adviser believes that a company's earnings
growth is the primary determinant of its potential long-term return and
considers several factors in its evaluation of a company, including:
- -     earnings growth prospects of a company's industry and sector,
- -     potential for above average long-term earnings and revenue growth,
- -     unique product or service, - growing product demand,
- -     regional or country dominance and growing market share,
- -     management experience and capabilities, and
- -     strong financial strategy.

The Fund may invest in securities representing underlying international
securities such as American Depository Receipts, European Depository Receipts
and Global Depository Receipts.

In order to hedge against adverse movements in currency exchange rates, the Fund
may from time to time enter into forward foreign currency exchange contracts.

PRINCIPAL INVESTMENT RISKS

All investments carry some degree of risk which will affect the value of a
Fund's investments, investment performance and price of its shares. IT IS
POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUNDS.

The principal risks of investing in the Funds include:

RISKS THAT APPLY TO ALL FUNDS

- -     Stock Market Risk: The value of the stocks in which a Fund invests may go
      up or down in response to the activities of individual companies, the
      stock market and general economic conditions. Stock prices may decline
      over short or extended periods. As of the date of this Prospectus, U.S.
      stock markets and certain foreign markets are trading at or close to
      record high levels. There is no guarantee that such levels will continue.

- -     Management Risk: A strategy used by the investment management team may not
      produce the intended results.

- -     Liquidity Risk: Certain securities may be difficult to sell at the time
      and price that the Adviser would like to sell. The Adviser may have to
      lower the selling price, sell other securities instead or forego an
      investment opportunity, any of which could have a negative effect on fund
      performance. During unusual market conditions, unusually high volume of
      redemption requests or other reasons, the Fund may not be able to pay
      redemption proceeds within the time periods described in this Prospectus.

- -     Foreign Securities Risk: To the extent a Fund invests in foreign
      securities, including American Depository Receipts (U.S.
      dollar-denominated receipts representing shares of foreign-based
      corporations), the Fund will be subject to additional risks than those
      associated with domestic investments. Additional risks include currency
      fluctuations, political and economic instability, differences in financial
      reporting standards and less stringent regulation of securities markets.

- -     Year 2000 Risk: The Year 2000 issue arises when computer programs
      represent dates as two digits instead of four. Such programs may
      incorrectly assume that the year after 1999 is 1900. The Funds could be
      adversely affected if the computer systems used by the Funds, the Adviser,
      Sub-Adviser, or other service providers and entities with computer systems
      that are linked to the Funds' records do not properly process and
      calculate date-related information and data on and after January 1, 2000.

      A comprehensive review of the third-party service providers' and the
      Adviser's and Sub-Adviser's computer systems and business processes has
      been conducted to identify the major systems that could be affected by the
      Year 2000 issue. Steps are being taken to resolve any potential problems
      including modification of existing software and the purchase of new
      software. In addition, the Adviser evaluates the anticipated impact of
      year 2000 issues on each company and government security in which the
      Funds invest. However, there can be no assurance that these steps will be
      sufficient to avoid any adverse impact on the Funds. The risk may be of
      greater significance with respect to a Fund's investment in securities of
      foreign issuers.

RISKS THAT APPLY PRIMARILY TO THE BALANCED FUND

- -     Interest Rate Risk: Due to the Fund's investments in fixed-income
      securities, an increase in interest rates may lower the Fund's value and
      the overall return on your investment. The magnitude of this decrease is
      often greater for longer-term fixed income securities than shorter-term
      securities.

- -     Prepayment Risk: Declining interest rates may compel borrowers to prepay
      mortgages and debt obligations underlying the mortgage-backed securities
      and manufactured home loan pass-through securities owned by the Fund. The
      proceeds received by the Fund from prepayments will likely be reinvested
      at interest rates lower than

<PAGE>


      the original investment, thus resulting in a reduction of income to the
      Fund. Likewise, rising interest rates could reduce prepayments and extend
      the life of securities with lower interest rates, which may increase the
      sensitivity of the Fund's value to rising interest rates.

- -     Credit Risk: The issuers or guarantors of fixed-income securities owned by
      the Fund may default on the payment of principal or interest, or on other
      obligations to the Fund, causing the value of the Fund to decrease.

- -     Income Risk: The income you earn from the Fund may decline due to
      declining interest rates.

- -     Call Risk: Many bonds may be redeemed ("called") at the option of the
      issuer before their stated maturity date. In general, an issuer will call
      its bonds if they can be refinanced by issuing new bonds which bear a
      lower interest rate. The Fund would then be forced to invest the
      unanticipated proceeds at lower interest rates, resulting in a decline in
      the Fund's income.

RISK THAT APPLIES PRIMARILY TO THE SMALL CAP GROWTH, REGIONAL GROWTH AND SCIENCE
AND TECHNOLOGY GROWTH FUNDS

- -     Small Cap Stock Risk: Stocks of smaller companies may be subject to more
      abrupt or erratic market movements than stocks of larger, more established
      companies. Small companies may have limited product lines or financial
      resources, or may be dependent upon a small or inexperienced management
      group. In addition, small cap stocks typically are traded in lower volume,
      and their issuers typically are subject to greater degrees of changes in
      their earnings and prospects.

RISK THAT APPLIES PRIMARILY TO THE SCIENCE AND TECHNOLOGY GROWTH FUND

- -     Technology Stock Risk: Stocks of science and technology companies may be
      subject to greater price volatility than stocks of companies in other
      sectors or the overall stock market. Science and technology companies may
      produce or use products or services that prove commercially unsuccessful,
      become obsolete or become adversely impacted by government regulation.
      Technology stocks may experience significant price movements caused by
      disproportionate investor optimism or pessimism. The Fund may be more
      affected by events influencing these sectors than a fund that is more
      diversified across numerous sectors.

RISK THAT APPLIES PRIMARILY TO THE REGIONAL GROWTH FUND

- -     Risk of Geographic Limitation: Regional Growth Fund's policy of investing
      primarily in a certain in a geographic region means that the Fund will be
      subject to adverse economic, political or other developments in that
      region. The region in which the Fund principally invests has a diverse
      industrial base (including agriculture, mining, retail, transportation,
      utilities, heavy and light manufacturing, financial services, insurance,
      computer technology and medical technology), however, this industrial base
      is not as diverse as that of the country as a whole. The Fund therefore
      may be less diversified by industry and company than other funds with a
      similar investment objective and no geographic limitation.

RISKS THAT APPLY PRIMARILY TO THE INTERNATIONAL GROWTH AND DEVELOPING MARKETS
GROWTH FUNDS

- -     Risks of International Investing: International investing involves risks
      not typically associated with domestic investing. Because of these risks,
      and because of the Sub-Adviser's ability to invest substantial portions of
      the Funds' assets in a small number of countries, the Funds may be subject
      to greater volatility than mutual funds that invest principally in
      domestic securities.

- -     Currency Risk: The value of the Funds' securities computed in U.S. dollars
      will vary with increases and decreases in exchange rates. A decline in the
      value of any particular currency against the U.S. dollar will cause a
      decline in the U.S. dollar value of a Fund's holdings of securities
      denominated in that currency.

<PAGE>


- -     Political and Economic Risk: Investing in securities of non-U.S. companies
      may entail additional risks due to the potential political, social and
      economic instability of certain countries, changes in international trade
      patterns, the possibility of the imposition of exchange controls,
      expropriation, limits on removal of currency or other assets and
      nationalization of assets.

- -     Foreign Tax Risk: Each Fund's income from foreign issuers may be subject
      to non-U.S. withholding taxes. In some countries, the Funds also may be
      subject to taxes on trading profits and, on certain securities
      transactions, transfer or stamp duties tax. To the extent foreign income
      taxes are paid by a Fund, U.S. shareholders may be entitled to a credit or
      deduction for U.S. tax purposes. See the Statement of Additional
      Information for details.

- -     Risk of Investment Restrictions: Some countries, particularly developing
      markets, restrict to varying degrees foreign investment in their
      securities markets. In some circumstances, these restrictions may limit or
      preclude investment in certain countries or may increase the cost of
      investing in securities of particular companies.

- -     Foreign Securities Market Risk: Securities of many non-U.S. companies may
      be less liquid and their prices more volatile than securities of
      comparable U.S. companies. Securities of companies traded in many
      countries outside the U.S., particularly developing markets countries, may
      be subject to further risks due to the inexperience of local brokers and
      financial institutions, the possibility of permanent or temporary
      termination of trading, and greater spreads between bid and asked prices
      for securities. In addition, non-U.S. stock exchanges and brokers are
      subject to less governmental regulation, and commissions may be higher
      than in the United States. Also, there may be delays in the settlement of
      non-U.S. stock exchange transactions.

- -     Information Risk: Non-U.S. companies generally are not subject to uniform
      accounting, auditing and financial reporting standards or to other
      regulatory requirements that apply to U.S. companies. As a result, less
      information may be available to investors concerning non-U.S. issuers.
      Accounting and financial reporting standards in developing markets may be
      especially lacking.

- -     Risks of Developing Markets: Investing in securities of issuers in
      developing markets involves exposure to economic infrastructures that are
      generally less diverse and mature than, and to political systems that can
      be expected to have less stability than, those of developed countries.
      Other characteristics of developing market countries that may affect
      investment in their markets include certain governmental policies that may
      restrict investment by foreigners and the absence of developed legal
      structures governing private and foreign investments and private property.
      The typical small size of the markets for securities issued by issuers
      located in developing markets and the possibility of low or nonexistent
      volume of trading in those securities may also result in a lack of
      liquidity and in price volatility of those securities. In addition,
      issuers in developing markets typically are subject to a greater degree of
      change in earnings and business prospects than are companies in developed
      markets.

- -     Risks of Foreign Currency Hedging Transactions: If the Sub-Advisor's
      forecast of exchange rate movements is incorrect, the Funds may realize
      losses on its foreign currency transactions. In addition, the Funds'
      hedging transactions may prevent the Funds from realizing the benefits of
      a favorable change in the value of foreign currencies.

      used to compare performance, however, the Adviser now believes the S&P 500
      Index to be a more appropriate broad-based securities market index with
      which to compare performance, for two main reasons: The Fund contains a
      significant amount of health care stocks, unlike the PSE Tech 100 Index,
      and the S&P 500 Index is the most commonly used Index for Science &
      Technology sector funds.

FEES AND EXPENSES

This table shows fees and expenses that you may pay if you buy and hold shares
of the Funds. All Sit Mutual Funds are 100% no-load investments, so you will not
pay any shareholder fees such as sales loads, redemption fees or exchange fees
when you buy or sell shares of the Funds. However, when you hold shares of a
Fund you indirectly pay a portion of the Fund's operating expenses. These
expenses are deducted from Fund assets.

(1) Management fee does not reflect the Adviser's waiver of fees. Actual
expenses are lower than those shown in the table because of voluntary fee
waivers by the Adviser. As a result of the fee waiver, actual management fees
paid by the Regional Growth, Mid Cap Growth, International Growth, and Science
and Technology Growth Funds were 1.00%, 1.00% 1.50%, and 1.25%, respectively, of
the Fund's average daily net assets. After December 31, 2000, the fee waivers
may be terminated at any time by the Adviser.

EXAMPLE

This example is intended to help you compare the cost of investing in each Fund
(before the fee waiver) with the cost of investing in other mutual funds. It
assumes that you invest $10,000 in a Fund for the time periods indicated (with
reinvestment of all dividends and distributions), that your investment has a 5%
return each year, that the Fund's operating expenses remain the same, and that
you redeem all of your shares at the end of those periods. Although your actual
costs and returns may differ, based on these assumptions your costs would be:

- --------------------------------------------------------------------------------
SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

SHARE PRICE

Your price for purchasing, selling, or exchanging shares is based on the Fund's
net asset value (NAV) per share, which is calculated as of the close of regular
trading on the New York Stock Exchange (generally 3:00 p.m. Central time) every
day the exchange is open. The NAV per share of the other Funds will fluctuate.

                        [*Sidebar]: A Fund's share price or NAV is determined by
                        adding the total value of a Fund's investments and other
                        assets (including accrued income), subtracting its
                        liabilities, and then dividing that figure by the number
                        of outstanding shares of the Fund.

NAV is based on the market value of the securities in a fund's portfolio. When
market value prices are not readily available, fair value is determined in good
faith by the Adviser using methods approved by the board of directors.
Short-term debt securities maturing in less than 60 days are valued at amortized
cost. The amortized cost method of valuation initially values a security at its
purchase cost, then consistently adjusts the cost value by

<PAGE>


amortizing/accreting any discount or premium paid until the security's maturity
without regard to fluctuating interest rates.

WHEN ORDERS ARE EFFECTIVE

Purchase, exchange, and sale orders are received and may be accepted by Sit
Mutual Funds only on days the New York Stock Exchange ("NYSE") is open.
PURCHASE, EXCHANGE, AND SALE ORDERS RECEIVED PRIOR TO THE CLOSE OF THE NYSE
(GENERALLY 3:00 P.M. CENTRAL TIME) ARE INVESTED OR SOLD AT THE NET ASSET VALUE
PER SHARE CALCULATED FOR THAT BUSINESS DAY, EXCEPT PURCHASES MADE TO AN EXISTING
ACCOUNT VIA AUTOMATED CLEARING HOUSE, "ACH," ELECTRONIC TRANSFER OF FUNDS. ACH
PURCHASES ARE INVESTED AT THE NET ASSET VALUE PER SHARE ON THE NEXT BUSINESS DAY
AFTER YOUR TELEPHONE CALL TO THE FUNDS IF YOU CALL THE FUNDS PRIOR TO THE CLOSE
OF THE NYSE. Your bank account will be debited within 1 to 2 business days.

IF YOUR PURCHASE, EXCHANGE, OR SALE ORDER IS RECEIVED AFTER THE CLOSE OF THE
NYSE, THE PURCHASE, EXCHANGE OR SALE WILL BE MADE AT THE NET ASSET VALUE
CALCULATED ON THE NEXT DAY THE NYSE IS OPEN.

The Funds may reject or restrict any purchase or exchange order at any time,
when, in the judgment of management, it is in the best interests of the Funds.
For example, it may be in the best interests of the Funds to reject purchase and
exchange orders that are short-term or restrict excessive trading into and out
of the Funds since such orders may harm performance by disrupting portfolio
management strategies and increasing expenses.

PURCHASING SHARES

Shares of the Funds may be purchased on any day the NYSE is open with a minimum
initial investment of $2,000. If you establish an on-going Automatic Investment
Plan, the minimum initial investment is $500. If you open a retirement,
education, or UGMA or UTMA account, there is no minimum initial investment
amount.

Once an account is opened, additional investments must be at least $100, except
for retirement, education, and UGMA / UTMA accounts which have no minimum
additional investment amount.

INITIAL PURCHASE BY MAIL
You may complete and sign an account application and mail it to the Funds as
instructed on the application. Enclose a check made payable to Sit Mutual Funds.
Third party checks are not accepted.

INITIAL PURCHASE BY WIRE
You may have your bank wire Federal Funds to purchase shares of the Funds. Your
bank may charge you a wire fee. Before money is wired for an initial purchase
(new account), you must fax a copy of a completed account application to Sit
Mutual Funds. The Funds will provide you with an account number and wiring
instructions.

After opening an account by wire transfer, you must mail the completed account
application containing original signatures to Sit Mutual Funds. If a completed

processing by the banks, are not the responsibility of the Funds or the Funds'
Transfer Agent.

wire purchase through your bank, notify Sit Mutual Funds that a wire purchase is
being made to your account.

ADDITIONAL PURCHASES BY ACH

selected this option on the account application. To add this option to an
existing account, complete the Change of Account Options form. This option will
begin within 10 days of the Fund's receipt of the change form. To place an ACH
purchase order, call an Investor Services Representative at 1-800-332-5580. Your

have completed the Automatic Investment Plan section of the account application.
To add this option to an existing account, complete the Change of Account
Options form. This option will begin within 10 days of the Fund's receipt of the
change form. You can change the amount or terminate this option by written
notice to the Funds at any time.

EXCHANGING SHARES

You may sell shares of one Fund and use the proceeds to buy shares of another
Sit Mutual Fund, at no cost. Before making an exchange, you should read the
prospectus and consider the investment objective of the Fund to be purchased.

An exchange of shares is a sale for federal income tax purposes and you may have
a taxable capital gain or loss.

You may make an exchange to an existing account or to a new account. If your
exchange creates a new account, the new account ownership must be identical and
you must satisfy the minimum initial investment amount.

EXCHANGE BY TELEPHONE
You may exchange shares between the Funds by telephone. The exchange privilege
is automatically established when you open your account, unless you indicate
that you do not want the exchange privilege.

EXCHANGE BY MAIL
You may exchange shares between the Funds by written request to the Funds. A
written request must be signed by all registered owners of the account.

EXCHANGE BY AUTOMATIC EXCHANGE PLAN
You may exchange fixed periodic amounts from one Fund to another Fund on any
business day of the month if you have completed the Automatic Exchange section
of the account application. An exchange may be done monthly, or you may choose
which months you wish to have the exchange made. To add this option to an
existing account, complete the Change of Accounts Options form.

<PAGE>


EXCHANGE BY AUTOMATIC EXCHANGE PLAN
You may exchange shares between the Funds by using the automated telephone line
at 1-800-332-5580 and following the instructions. You should have your personal
identification number, account number, and fund numbers available.

SELLING SHARES

You may sell all or a portion of your shares on any day when the NYSE is open,
at no cost. You may receive more or less than your cost depending on the market
value of the Fund's securities. A request to sell cannot be canceled or revoked.

SELL BY MAIL
You may sell shares by sending a written request to Sit Mutual Funds that
includes the following information:
- -     Name of the Fund;
- -     Name(s) on the account;
- -     Account number;
- -     Dollar amount or number of shares to be redeemed;
- -     Other supporting legal documents as required for estates, trusts,
      guardianships, custodianships, corporations, pension and profit sharing
      plans and other organizations;
- -     Directions specifying whether you want to receive the proceeds by mail,
      fed wire or ACH (see "Payment of Sale Proceeds" below for additional
      information you must include in your written request);
- -     Signatures of all registered account owners, exactly as their names appear
      on the account. THE SIGNATURE MUST BE GUARANTEED IF:
      (a)   You would like the proceeds from the sale to be paid to anyone other
            than the registered account owner(s), or
      (b)   You would like the check mailed to an address other than the
            registered address, or
      (c)   You want the proceeds sent via bank wire to a bank different than
            the bank authorized by you on your account application.

                        [*Sidebar]: A signature guarantee assures that a
                        signature is genuine a and protects shareholders from
                        unauthorized account transfers. Most banks, brokerage
                        firms, and other financial institutions guarantee
                        signatures.

                        [*Sidebar]: Call your financial institution to determine
                        if it has this capability. A notary public stamp or seal
                        cannot be substituted for a signature guarantee.

You will receive the proceeds from the sale of shares according to the method
you indicate in your written request - either by mail, wire or ACH.

SELL BY TELEPHONE
You may sell shares, up to $50,000 per day, by calling Sit Mutual Funds if you
completed the Banking Authorization section and the Telephone Redemption section
of the account application for each account that you want the option. To add
this option to an existing account, or to change your banking information
provided on the application, you must complete a Change of Account Options form.
A signature guarantee is required with the change form if you are changing the
address or bank account to where we will send your redemption proceeds. The
$50,000 limitation does not apply to omnibus accounts. For purposes of this
limitation, accounts with the same registration in different Funds will be
aggregated.

You will receive the proceeds from the sale of shares according to the method
you chose in the Telephone Redemption section of the account application -
either by mail, wire, or ACH.

<PAGE>


SELL BY AUTOMATIC WITHDRAWAL PLAN
You may sell shares through an Automatic Withdrawal Plan and receive sales
proceeds of at least $100 on a monthly, quarterly, semi-annual or annual basis
if you have completed the Special Services section of the account application.
To add this option to an existing account, you must complete the Change of
Accounts Options form. This option will begin within 10 days of the Fund's
receipt of the change form. Automatic withdrawals may eventually exhaust your
account. Each withdrawal constitutes a sale for federal income tax purposes and
you may have a taxable capital gain or loss.

You will receive the proceeds from the sale of shares according to the method
you chose in the Special Services section of the account application - either by
mail or ACH.

PAYMENT OF SALE PROCEEDS
Your sale proceeds generally will be paid as soon as possible, generally not
later than seven business days after receipt of a request to sell. HOWEVER, IF
YOUR SHARES WERE RECENTLY PURCHASED WITH NONGUARANTEED FUNDS, SUCH AS A PERSONAL
CHECK, AND YOU REQUEST TO SELL SHARES OR YOU WRITE A DRAFT ON YOUR ACCOUNT, YOUR
SALES PROCEEDS CHECK MAY BE DELAYED UNTIL YOUR CHECK CLEARS, WHICH MAY TAKE UP
TO 15 DAYS, OR THE FUND MAY RETURN YOUR DRAFT. YOU MAY AVOID THIS DELAY BY
PURCHASING SHARES WITH A BANK WIRE OF FEDERAL FUNDS.

You may receive proceeds from the sale of your shares in one of three ways:

1.    BY MAIL. AVAILABLE FOR SALES INITIATED BY A WRITTEN OR TELEPHONE REQUEST
      OR AN AUTOMATIC WITHDRAWAL PLAN. We can mail a check of the proceeds from
      the sale of shares to your address of record. If you would like the check
      mailed to an address other than the address of record, you must submit a
      written sales request which includes the alternative address and a
      SIGNATURE GUARANTEE. Your check will generally be mailed to you within 7
      business days after receipt of your request to sell.

2.    BY WIRE. AVAILABLE FOR SALES INITIATED BY A WRITTEN OR TELEPHONE REQUEST.
      We can transmit the proceeds from the sale of shares by wire to your bank
      account. If you have not provided wire instructions with the banking
      information on your application, or if the wire instructions are different
      than previously provided, you must submit a written sales request which
      includes wire instructions, the bank's address, and a SIGNATURE GUARANTEE.
      Your bank account usually will be credited within 1 to 2 business days
      after the Funds receive your written or telephone request to sell shares.

      The Funds' bank charges a wire fee (currently $8) which will be deducted
      from the balance of your account or from the amount being wired if your
      account has been completely redeemed. The recipient bank may also charge a
      wire fee.

3.    BY ACH. AVAILABLE FOR SALES INITIATED BY A WRITTEN REQUEST, TELEPHONE
      REQUEST, OR AUTOMATIC WITHDRAWAL PLAN. We can send ACH proceeds from the
      sale of shares for non-IRA accounts to your bank account. Your bank
      account usually will be credited within 1 to 2 business days after the
      Funds receive your request to sell shares.

INVOLUNTARY REDEMPTIONS
If your account balance in a Fund falls below $2,000 as a result of selling or
exchanging shares, the Fund has the right to redeem your shares and send you the
proceeds. Before redeeming your account, the Fund will mail you a notice of its
intention to redeem, which will give you an opportunity to make an additional
investment. If you do not increase the value of your account to at least $2,000
within 30 days of the date the notice was mailed, the Fund may redeem your
account. The $2,000 minimum balance requirement does not apply to retirement,
education, UGMA or UTMA accounts, or if you have established an on-going
Automatic Investment Plan.

INVESTING THROUGH A THIRD PARTY

There is no charge to invest, exchange, or sell shares when you make
transactions directly through Sit Mutual Funds.

<PAGE>


If you invest in the Funds through a third party, rather than directly with Sit
Mutual Funds, the fees and policies may be different than described in this
Prospectus. Banks, brokers, 401(k) plans, financial advisors, and financial
supermarkets may charge commissions and transaction fees and may set different
minimum investments or limitations on purchasing or selling shares. Consult a
representative of your plan or financial institution if you are unsure of their
fees and policies.

DIVIDENDS AND DISTRIBUTIONS

Dividends from a Fund's net investment income are declared daily and paid
monthly. Net investment income includes dividends on stocks and interest earned
on bonds or other debt securities less operating expenses.

Capital gains, if any, are distributed at least once a year by each Fund. A
capital gain occurs if a Fund sells portfolio securities for more than its cost.

Dividend and capital gain distributions are automatically reinvested in
additional shares of the Fund paying the distribution at the net asset value per
share on the distribution date. However, you may request that distributions be
automatically reinvested in another Sit Mutual Fund, or paid in cash. Such
requests may be made on the application, Change of Accounts Options form, or by
written notice to Sit Mutual Funds. You will receive a quarterly statement
reflecting the dividend payment and, if applicable, the reinvestment of
dividends. If cash payment is requested, an ACH transfer will be initiated, or a
check normally will be mailed within five business days after the payable date.
If the check cannot be delivered because of an incorrect mailing address, the
undelivered distributions and all future distributions will automatically be
reinvested in Fund shares. No interest will accrue on uncashed distribution,
dividend, or sales proceeds checks.

RETIREMENT AND OTHER TAX-DEFERRED ACCOUNTS

Taxes on current income can be deferred by investing in Keogh plans, Individual
Retirement Accounts (IRAs), Simplified Employee Pensions (SEPs), 401(k),
pension, profit-sharing, employee benefit, deferred compensation and other
qualified retirement plans.

The Funds are available for your tax-deferred retirement plan with no minimum
investment requirements for initial or subsequent contributions. Such retirement
plans must have a qualified plan sponsor or trustee. The Adviser sponsors
prototype 401(k), profit sharing, and money purchase plans as well as IRA,
SEP-IRA and Keogh plans. You should contact the Adviser for specific plan
documentation.

The Funds are also available for Education IRAs, which are vehicles for saving
for post-secondary education on a tax-deferred basis. Contributions to an
Education IRA cannot be made after the minor turns age 18, and are not
deductible for tax purposes.

The federal tax laws governing these tax-deferred plans must be complied with to
avoid adverse tax consequences. You should consult your tax adviser before
investing.

TAXES

Some of the tax consequences of investing in the Funds are discussed below. More
information about taxes is in the Statement of Additional Information. However,
because everyone's tax situation is unique, always consult your tax professional
about federal, state and local tax consequences.

TAXES ON DISTRIBUTIONS
Each Fund pays its shareholders distributions from its net investment income and
any net capital gains that it has realized. For most investors, these
distributions will be taxable, whether paid in cash or reinvested.

<PAGE>


Distributions paid from a Fund's net investment income and short-term capital
gains, if any, are taxable as ordinary income. Distributions paid from a Fund's
long-term capital gains, if any, are taxable as long-term capital gains,
regardless of how long you have held your shares (unless your investment is in
an IRA or other tax-advantaged account).

TAXES ON TRANSACTIONS
The sale or exchange of your shares in a Fund is a taxable transaction, and you
may incur a capital gain or loss on the transaction. If you held the shares for
more than one year, such gain or loss would be a long-term gain or loss. A gain
or loss on shares held for one year or less is considered short-term and is
taxed at the same rates as ordinary income.

ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------

OTHER SECURITIES, INVESTMENT PRACTICES, AND POLICIES

The principal investment strategies and risk factors of each Fund are outlined
in the section entitled "Fund Summaries." Below are brief discussions of certain
other investment practices of the Funds, and certain additional risks of
investing in the Funds. Each Fund may invest in securities and use investment
strategies that are not described in this Prospectus but are described in the
Statement of Additional Information.

DURATION
Duration measures how much the value of a security is expected to change with a
given change in interest rates. Effective duration is one means used to measure
interest rate risk. The longer a security's effective duration, the more
sensitive its price to changes in interest rates. For example, if interest rates
rise by one percent, the market value of a security with an effective duration
of two years would decrease by 2%, with all other factors being constant. The
Adviser uses several methods to compute duration estimates appropriate for
particular securities held in the Funds' portfolios. Duration estimates are
based on assumptions by the Adviser and subject to a number of limitations.
Duration is most useful when interest rate changes are small, rapid, and occur
equally in short-term and long-term securities. In addition, it is difficult to
calculate precisely for bonds with prepayment options, such as mortgage-related
securities, because the calculation requires assumptions about prepayment rates.

PORTFOLIO TURNOVER
The Funds may trade securities frequently, resulting, from time to time, in an
annual portfolio turnover rate of over 100%. Trading of securities may produce
capital gains, which are taxable to shareholders when distributed. Active
trading may also increase the amount of commissions or mark-ups to broker
dealers that the Fund pays when it buys and sells securities, which may decrease
the Fund's yield. The "Financial Highlights" section of this Prospectus shows
each Fund's historical portfolio turnover rate.

SECURITIES RATINGS
When debt securities are rated by one or more independent rating agencies, the
Adviser uses these ratings to determine bond quality. Investment-grade debt
securities are those that are rated within the four highest rating categories,
which are AAA, AA, A, and BBB by Standard & Poor's Corporation, Fitch IBCA, and
Duff & Phelps Credit Rating Company, and Aaa, Aa, A and Baa by Moody's Investor
Services. If a debt security's credit quality rating is downgraded after a
Fund's purchase, the Adviser will consider whether any action, such as selling
the security, is warranted.

INVESTMENT IN THE SIT MONEY MARKET FUND
Each Fund may invest up to 25% of its total net assets in shares of the money
market funds advised by the Adviser, which includes the Sit Money Market Fund,
subject to the conditions contained in an exemptive order issued to the Funds by
the Securities and Exchange Commission. These investments may be made in lieu of
direct investments in short-term money market instruments if the Adviser
believes that they are in the best interest of the Funds.

TEMPORARY DEFENSIVE INVESTING
For temporary defensive purposes in periods of unusual market conditions, each
Fund may invest all of its total assets in cash or short-term debt securities
including certificates of deposit, bankers' acceptances and other bank
obligations, corporate and direct U.S. obligation bonds, notes, bills,
commercial paper and repurchase agreements.

FINANCIAL HIGHLIGHTS

The tables that follow present performance information about the shares of each
Fund. This information is intended to help you understand each Fund's financial
performance for the past five years (or, if shorter, the period of the Fund's
operations). Some of this information reflects financial results for a single
Fund share. The total returns in the tables represent the rate that you would
have earned or lost on an investment in a Fund, assuming you reinvested all of
your dividends and distributions. This information has been audited by KPMG LLP,
independent auditors, whose report, along with the Funds' financial statements,
is included in the Funds' annual report, which is available upon request.

SIT MUTUAL FUNDS
CHAIRMAN'S LETTER - YEAR ENDED JUNE 30, 1999

[PHOTO]

Dear Fellow Shareholders:

     Despite considerable volatility in the global economic environment marked
by investor concerns first of deflation in late 1998 and then inflation in
mid-1999, most major equity market indices moved solidly higher over the last
twelve months.

Economic Overview

     June represented the 100th month of the U.S. economic expansion, a long
cycle characterized by positive and balanced growth, generally declining
interest rates, subdued inflation, and record-setting gains in aggregate
employment. The resilience of consumer spending continues to be the primary
driver behind the above-trend growth for the U.S. economy. Over the last four
quarters, annualized growth in Gross Domestic Product (GDP) has averaged +4.1%,
a remarkable achievement given the turmoil in many economies throughout the
world. Since Personal Consumption Expenditures (PCE) now account for over
two-thirds of GDP, the +5.0% year-over-year gain over the last twelve months was
strong enough to overcome weakness in other components, particularly the severe
decline in net exports. Several factors suggest that real GDP growth will be
somewhat below the pace witnessed over the past year, although above the +2.3%
rate for the second quarter. First, consumer spending appears to be
decelerating, as second quarter PCE increased by +4.0%, down from the increase
of +6.7% in the first quarter. Second, we do not believe that consumer spending
will remain as robust if the savings rate continues in negative territory.
Third, fixed mortgage rates have increased nearly 100 basis points since the
beginning of the year, which has served to impede housing demand; however, given
the generally strong level of consumer confidence and continued high levels of
housing investment and consumer durables spending, together with capital
investment by business, we expect only a modest slowing in GDP growth for the
remainder of the year compared to the robust +4.1% average over the past twelve
months. Our expectation for calendar 1999 GDP growth is +3.8%.

     In terms of inflation data, the news remains mixed. May and June Consumer
Price Index (CPI) reports showed no change from the previous month, which was
considerably better than expectations. The National Association of Purchasing
Managers Prices Paid Index, however, has increased for six consecutive months,
and although the June Producer Price Index showed a decrease for finished goods,
there have been monthly increases in intermediate and crude goods.

     The government's data releases on July 29th also contained mixed messages.
While GDP growth slowed to +2.3% in the second quarter, the
stronger-than-expected +3.2% year-over-year increase in the Employment Cost
Index was greeted negatively. Inflation news will continue to be watched
intensely, but we expect only a moderate pick-up in the CPI data, which should
range between +2.0% and +2.5% for 1999.

     The Federal Reserve continues to be highly sensitive to inflation as
evidenced by its modest 25 basis point increase in the federal funds rate. More
importantly, the Fed changed its policy stance from a "tightening" to a
"neutral" bias, reducing fears of successive near-term rate increases. The
Chairman's recent Humphrey-Hawkins testimony indicated that inflation continues
to be a concern, despite the recent change in bias.

     As Mr. Greenspan stated in his address, "If new data suggest it is likely
that the pace of cost and price increases is picking up, the Federal Reserve
will have to react promptly and forcefully so as to preclude imbalances from
arising that would only require a more disruptive adjustment later."

     Among his key concerns are the tightness in the labor market, the
sustainability of productivity gains, and the potential ramifications of a stock
market "bubble." In terms of Federal Reserve policy, given our outlook for only
a modest acceleration in consumer inflation and a slight deceleration in GDP in
the second half of 1999, we believe the Fed may rest after one or two more 25
basis point increases.

     In terms of fiscal policy, escalating projections of federal budget
surpluses have tax-cut proponents calling for aggressive tax reductions--
especially since the non-Social Security operating surplus may be achieved as
early as fiscal-year 2000. If one can believe the typically overly optimistic
government projections, $2.9 trillion in total surpluses would be generated over
the next decade of which $1 trillion would be outside the Social Security
buildup. Tax bills are being worked on in both the House and Senate and, under
the most optimistic assumptions, a bill might be ready for the President by the
fall. If Democrats and Republicans fail to compromise on the myriad of issues
within a tax bill, the topic of taxation will be a focal issue in the 2000
election campaign. Another key fiscal event occurred in late June when the
President outlined a Medicare reform package. This included a prescription drug
program with a tax-cut-for-Medicare-drug-benefit deal also a possibility. The
new drug benefit is estimated to cost $118 billion over ten years with 60%
financed by what the Clinton administration has termed "savings from competition
and efficiency" and 40% from the expected surplus.

     From an international perspective, the outlook for global

economic growth continues to improve. Asian economies appear to be slowly
recovering from the "trough" experienced in fall of 1998. The Japanese economy,
most notably, is showing some signs of life. GDP growth in the most recent
quarter was a surprisingly strong +1.9%. Industrial production increased +3.0%
in June, and recent Bank of Japan business sentiment surveys have shown an
improvement over the March survey. Since the beginning of the year, various
European economies had mixed growth results that have led to an overall
slowdown. Weakness in Germany, Euroland's largest economy, has been a major
concern. We believe, however, that the German economy will be improving, largely
due to recovering Asian markets coupled with euro weakness, which has prompted
an improvement in exports. Thus far in 1999, Latin American financial markets
responded favorably to stabilization in the currencies; however, the region's
economies remain weak because many Latin American countries are large producers
of worldwide commodities whose prices, except for oil, remain depressed. We are
forecasting +2.0% global GDP growth in 1999, due to accelerating growth in
Europe, improving economic growth prospects in non-Japan Asia, bottoming of the
recession in Japan, and gradual slowing in the United States.

Equity Strategy Summary

     Domestic stock indices were generally higher over the last twelve months,
with virtually all mid and large capitalization indices posting double-digit
returns. Two major changes in investment sentiment that may have future
investment implications occurred during the second quarter of 1999. First,
although larger cap issues have dramatically outperformed smaller stocks over
the past year (the Russell 1000 outperfomed the Russell 2000 by over 20
percentage points), small stocks came to life in the second quarter of 1999.
Extreme undervaluation of small stocks and renewed confidence in the global
economic environment were key elements behind the strong second quarter rally
for small cap stocks. In fact, this was the first quarter in seven that the
Russell 2000 Index outperformed the Russell 1000 Index. Given the duration and
magnitude of small cap underperformance in recent years, and the resulting
valuation disparity, we believe the potential exists for an extended small cap
rally. The second significant change in equity markets was the rebound in
economically sensitive, cyclical issues that had previously been depressed by
fears of an economic slowdown. While we believe that the economic backdrop has
generally improved the prospects for cyclical companies, it appears that a
significant portion of the anticipated improvement in the earnings cycle has
already been discounted in stock prices.

     Although the rise in interest rates has caused volatility in the equity
markets, stocks have been able to advance because corporate earnings news has
been generally positive. It appears as though second quarter operating earnings
for the S&P 500 Index will show solid double-digit growth, and we estimate that
over two-thirds of companies were able to exceed analysts' consensus
expectations. Although a brightening earnings outlook has prompted a tug-of-war
among small cap/large cap and growth/value investment styles in recent months,
our expectation for a moderately slowing U.S. economy implies a continued
positive environment for growth stock investing.

     Despite some valuation measures for the stock market being at extended
levels, many companies within the S&P 500 Index below the top 20 in
capitalization are at reasonable valuations in the context of current interest
rates and inflation levels. While the current S&P 500 Index
capitalization-weighted price-to-earnings ratio of 28.3x is the highest in 35
years, the median valuation is a much more reasonable 20.3x. These statistics
suggest that the very largest stocks in the Index (including such names as
Microsoft, GE, and Coca Cola) are disproportionately raising
capitalization-weighted valuation measures and obscuring the more reasonable
valuation for the broader market.

     International investment performance has varied widely among markets so far
in 1999. There is continued evidence of an improving global economy fueled by
particularly strong performance in emerging markets. While sluggish economic
growth and investors' reallocation of assets to Asia have caused some weakness
in European equity markets, we believe performance will improve as key European
economies slowly improve, corporate restructuring continues, and mergers and
acquisition activity accelerates. Brightened economic prospects have led us to a
much more positive view on Asia, particularly Japan. Concerns over upcoming
elections and the region's economic reliance on commodity prices have led us to
underweight Latin America versus global benchmarks.

     We greatly appreciate your support as shareholders in the Sit Mutual Funds.
With your investment objectives always in mind, we remain committed to seeking
out the best investment opportunities throughout the world.

SIT MUTUAL FUNDS
YEAR ENDED JUNE 30, 1999  PERFORMANCE REVIEW - STOCK FUNDS

                               STOCK FUNDS REVIEW

     Despite a great deal of quarterly volatility, global equity returns were
generally positive over the past twelve months.

     In the United States, large capitalization stocks continued to outperform
smaller issues, but there were signs of improvement in small cap stocks in the
latest quarter. For the year ended June 30, 1999, the S&P 500 Index total return
was +22.8%, over twenty percentage points higher than the +1.5% return for the
Russell 2000 Index. While small and mid cap stock cumulative returns over the
last twelve months were relatively moderate, investment sentiment may be
changing based on the strong performance in the most recent quarter. For the
quarter ending June 30, 1999, the Russell 2000 Index returned +15.6%,
considerably higher than the +7.1% return for the S&P 500 Index. Largely due to
fears of a global slowdown that persisted over the period, particularly in the
second half of 1998, growth stocks posted very strong results relative to value
issues. The Russell 1000 Growth Index advanced +27.3% over the past twelve
months, while the Russell 1000 Value Index increased by +16.4%. The Russell 2000
Growth Index return of +8.3% was fourteen percentage points higher than the
- -5.7% return for the Russell 2000 Value Index.

   Technology stocks, which are typically overweighted in Sit Mutual Funds
equity portfolios, performed exceptionally well over the past twelve months.
Within the Russell 1000 Growth Index, for example, both the Electronic
Technology and Technology Services sectors produced returns of over +60%.
Economically sensitive groups, including producer manufacturing,
consumer-durables, and process industries, lagged the market averages over the
period.

     International equity market indices also moved higher over the last twelve
months, although results varied widely by geographic region. The MSCI EAFE Index
gained +7.6%, with strong returns in most Asian markets offsetting somewhat
lackluster returns in Europe. Continued evidence of an economic recovery in
emerging markets has led to strong returns for the MSCI Emerging Markets Free
Index, which advanced +25.2% over the past twelve months, with almost all of the
gains occurring during the second quarter of 1999.

SIT BALANCED FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  SENIOR PORTFOLIO MANAGERS

           BRYCE A. DOTY, CFA

     The Sit Balanced Fund posted strong returns for the fiscal year ended June
30, 1999. The Fund's total return was +11.3%. The Lehman Aggregate Bond Index
gained +3.2% over the last twelve months while the S&P 500 Index increased
+22.8%. For the quarter ended June 30th, the Fund gained +0.5% while the Lehman
Aggregate Bond Index declined -0.9% and the S&P 500 gained +7.1%.

     As of June 30, 1999, the asset allocation of the Fund was 54% equities
(down from 56% at the end of March), 37% fixed income securities (down from
38%), and 9% cash reserve instruments (up from 6%).

     The equity portion of the portfolio produced solid returns over the last
twelve months, and investors are now focusing on improving earnings prospects
for U.S. companies amid an improved global economy. We believe that the market's
focus on strong earnings growth will benefit the equity securities held in the
Fund. As of June 30th, the projected growth rate for companies held in the Fund
was +21.6%, which is more than twice the projected growth rate for the S&P 500.
The Fund's holdings are concentrated in high unit growth companies with unique
products and strong management teams able to thrive in an intensely competitive
global business environment. This leads to significant positions in technology
and health care. We will continue to underweight slow growth, commodity-oriented
companies, and generally avoid such industries as chemicals, papers, autos, and
heavy equipment and machinery.

     While the improving global economy fueled the rally in equities over the
last quarter, bond prices suffered from fears over excessive economic growth.
Since bottoming at a 4.7% yield on October 5, 1998, U.S. Treasury bond yields
have risen about 130 basis points, and stood at just under 6% at the end of the
quarter. A recent change in fixed income strategy includes a sector shift to
increase U.S. Treasuries. In the coming months, we expect weakness in some
non-government sectors as investors become cautious due to of the Y2K
phenomenon. We are also increasing emphasis on securities with 5- to 10- year
average lives, which reflects a very flat yield curve that has reduced the
attractiveness of longer-maturity securities. The Fund will continue to focus on
high-quality securities that offer attractive total return opportunities.


                        INVESTMENT OBJECTIVE AND STRATEGY

      The Sit Balanced Fund's dual objectives are to seek long-term growth of
capital consistent with the preservation of principal and to provide regular
income. It pursues its objectives by investing in a diversified portfolio of
stocks, bonds and short-term instruments. The Fund may emphasize either equity
securities, fixed-income securities, or short-term instruments or hold equal
amounts of each, dependent upon the Adviser's analysis of market, financial and
economic conditions.

      The Fund's permissible investment allocation is: 40-60% in equity
securities, 40-60% in fixed-income securities, and up to 20% in short-term
fixed-income instruments. At all times at least 25% of the assets will be
invested in fixed-income senior securities.

SIT LARGE CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

     The Sit Large Cap Growth Fund posted strong performance during the fiscal
year ended June 30, 1999. The Fund's total return of +15.1% compared favorably
with the +13.6% return for the Lipper Growth and Income Index. Within the Lipper
Growth and Income Fund universe, the Fund's 1-year, 5-year and 10-year
annualized return was in the 47th, 8th and 17th percentile, respectively.

     Most U.S. stock market indices posted impressive gains over the last twelve
months, driven largely by continued strength in the domestic economy. Despite
lingering effects of the Asian crisis in the fall of 1998, and the subsequent
rise in interest rates, stock market returns have broadened considerably thus
far in 1999, and many indices are reaching or approaching new highs. Although a
brightened earnings outlook has prompted a tug of war among small/large cap and
growth/value investment styles in recent months, our expectation for a
moderately slowing U.S. economy implies a continued positive environment for
growth stock investing. Securities in the Fund continue to maintain projected
earnings growth rates far in excess of S&P 500 averages. In each of the next two
years, projected growth rates for securities held in the Fund exceed +20%, which
is more than twice the expected earnings gain for the S&P 500. Furthermore, as
inflation fears have subsided, growth stocks have significantly outperformed
value issues as the perception of risk surrounding their higher
price-to-earnings valuations has diminished.

     As of June 30th, the Fund was 93% invested in equities. Significant sector
weighting changes during the past year include increases in electronic
technology and health technology through the additions of Sun Microsystems,
International Business Machines, Raytheon, United Technologies, American Home
Products, and Amgen. Sector weighting decreases occurred in financial services
and consumer non-durables through the reduction or elimination of positions in
Citigroup, Franklin Resources, Mercury General, Unilever, and Gillette.

     Net assets in the Fund totaled $140.3 million at the end of June, up from
$117.5 million a year ago. We very much appreciate shareholders' continued
interest and participation in the Fund.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Large Cap Growth Fund is to maximize long-term capital
appreciation. The Fund pursues this objective by investing primarily in common
stocks of growth companies with a capitalization of $5 billion or more at the
time of purchase.

SIT REGIONAL GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  SENIOR PORTFOLIO MANAGER
           EUGENE C. SIT, CFA

     The Sit Regional Growth Fund rose +17.2% during the past year, while the
S&P 500's return was +22.8%. For the last quarter, the Fund's return was +7.0%
compared to the +7.1% return for the S&P 500. The Fund's performance
differential to the Index was essentially due to underweightings in the very
large companies outside of the Fund's regional focus. The Fund's cumulative
+32.0% return since inception, although lagging behind the
capitalization-weighted S&P 500 return, actually exceeds the estimated
equal-weighted capitalization return of +30.8% for the S&P Index. Because the
Fund's capitalization remains well below the popular large cap indices, the
widening breadth of the market during the second quarter bodes well for improved
relative performance going forward.

     Strong earnings growth continues to be the primary focus of the portfolio.
We project earnings growth rates of more than +21% for the next two
years--approximately three times the projected growth estimates for the S&P
500--for securities held in the Fund. Our enthusiasm for the Fund is based on
the attractive valuation relative to the market. Despite significantly higher
projected earnings growth rates, the Fund's weighted price-to-earnings valuation
is 26 (based on 1999 estimates), which is equivalent to the current earnings
multiple of the S&P 500.

     As of June 30th, the Fund was 95% invested in equity securities.
Significant sector weighting changes during the past year included increases in
electronic technology and technology services through the additions of Motorola,
National Computer Systems, Compuware, and First Data. Sector weighting decreases
occurred in financial services and health technology through the reduction or
elimination of positions in Charter One Financial, Household International,
Progressive, Hillenbrand, Stryker, and RP Scherer. Given the Fund's emphasis on
growth companies with unique product attributes, overweighted positions remain
in electronic technology and technology services.

     Given the Fund's strong earnings growth prospects, attractive valuations,
and existing opportunities within our geographic region, we remain enthusiastic
about the Fund's potential.

                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Fund is to maximize long-term capital appreciation.
The Fund pursues this objective by investing primarily in common stocks of
companies with their headquarters in Minnesota, Iowa, Missouri, North Dakota,
South Dakota, Nebraska, Kansas, Wisconsin, Illinois, Michigan, Indiana, and
Ohio. During normal market conditions, at least 80% of the Fund's total assets
will be invested in such securities. The Fund emphasizes securities of companies
that the Adviser believes have potential for long-term capital growth.

SIT MID CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  SENIOR PORTFOLIO MANAGERS
           EUGENE C. SIT, CFA
           ERIK S. ANDERSON, CFA

     During the June quarter of 1999, mid cap growth stocks rebounded strongly
and outperformed large cap growth stocks, as measured by the Frank Russell
Indices, for the first time in seven quarters. The Fund's quarterly return of
+11.2% compared favorably with the +10.4% return for the Russell Mid Cap Growth
Index.

     For the year ended June 30, 1999, the Sit Mid Cap Growth Fund return was
+6.9% versus the +20.3% for the Russell Mid Cap Growth Index. Although the
Fund's performance has lagged behind the Index, our capitalization restrictions
and valuation disciplines resulted in limited exposure to areas which drove the
Index higher, namely large stocks with capitalizations greater than $10 billion
and Internet stocks. For example, we estimate that just two stocks, Yahoo! and
Charles Schwab, contributed approximately +4.5% to the +20.3% return for the
Index over the last year. These companies have current market capitalizations of
over $35 billion and are well in excess of our Fund parameters.

     The recent outperformance of smaller cap issues can be attributed to
attractive valuations and renewed confidence in the global economy. Given the
dramatic differences in performance between mid and large cap issues over the
last two years, the potential for small and medium cap issues to catch up still
exists. Although the much publicized rally in cyclical stocks lifted value
stocks higher during the second quarter, growth issues in the mid cap sector
have significantly outperformed value issues on a year-to-date and twelve-month
basis. We believe that the Fund is very well positioned to capitalize on the
renewed market enthusiasm for smaller cap issues. The portfolio's average
projected earnings growth rate of +25% vastly exceeds the S&P 500's projected
growth rate of +10%.

     Significant sector weighting changes during the past year include increases
in electronic technology and health technology through the additions of
Uniphase, Vitesse Semiconductor, Jabil Circuit, Applied Micro Devices, and
Lexmark International. Sector weighting decreases occurred in financial services
and health services through the reduction or elimination of positions in First
American of Tennessee, Nac Re, Mercury General, McKesson HBOC, and Healthsouth
Corporation. As of June 30th, the Fund was 94% invested in equities.

     Given mid cap stocks' renewed momentum and strong growth prospects for the
companies in the portfolio, we remain optimistic about the Fund's outlook.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Sit Mid Cap Growth Fund is to maximize long-term
capital appreciation. The Fund pursues this objective by investing primarily in
the common stocks of growth companies with a capitalization of $2 billion to $15
billion at the time of purchase.

SIT INTERNATIONAL GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

     The Sit International Growth Fund's 1-year return of +4.5% compares with
the MSCI EAFE Index gain of +7.6% and the Lipper International Fund Index rise
of +4.0%. A major reason for the Fund's underperformance relative to the EAFE
Index was a sector rotation from growth to cyclical stocks in the first half of
1999. Market participants anticipated a faster pace of global economic growth
accompanied by an upturn in basic commodity prices.

     The Russian default in August 1998 was one of the most traumatic
experiences for the international markets last year. The EAFE Index declined
- -14.2% in the three months ended September 30, 1998, in part due to the
potential crisis associated with Long- Term Capital Management in the U.S.
Fortunately, the international equity markets were able to recover
substantially, enabling the Index to record a +20.7% gain in the December
quarter. Moreover, the first half of 1999 witnessed a lessening of market
volatility despite Brazil's currency devaluation. For the first six months of
1999, the Index increased by a modest +4.0%.

     Notably, the first half of 1999 was marked by an unexpectedly steep
depreciation of the euro (down -13%). As a result, the Fund's European portfolio
holdings declined in the Netherlands, Belgium, Ireland and the U.K.
Subsequently, the euro began to rebound against the dollar in July in response
to indications of improved economic growth in Germany and the U.K. We expect the
euro's upward trend to continue in the remainder of 1999, and we are targeting a
European portfolio weighting of 62%, up from 58.3% at the end of June.

     The Fund's Pacific Basin holdings increased to 12.9% of total assets vs.
the Index weighting of 6.6% due to the accelerating speed of recovery in the
crisis economies of Asia and ample liquidity. Recording substantial gains in
dollar terms were the Fund's holdings in Korea, Thailand and Hong Kong.

     From a long-term perspective, the upward momentum in the Japanese market is
even more significant now that a relapse in the economy appears unlikely;
therefore, the Fund's Japanese weighting climbed to 25.0% at mid-1999 (from
12.8% a year ago), compared with 24.0% for the Index. The Fund partially hedged
its Japanese holdings in early July to protect local currency gains in the
future. We expect renewed yen weakness based on a resumption of Japanese capital
outflow and a decreasing current account surplus.

     The objective of the Sit International Growth Fund is to achieve long-term
growth of capital by investing in equity securities of issuers domiciled outside
the United States. The Fund's investment objective reflects the belief that
long-term investment planning should include the investment opportunities that
exist outside the U.S.

     The Fund selects its investments based on the characteristics of the
particular markets and economies of the countries in which it invests. Emphasis
is placed on identifying securities of companies believed to be undervalued in
the marketplace in relation to factors such as the company's revenues, earnings,
assets and long-term competitive position which over time will enhance the
equity value of the company.

SIT SMALL CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  EUGENE C. SIT, CFA
           SENIOR PORTFOLIO MANAGER

     The Sit Small Cap Growth Fund's one-year return was +8.8% and compared
favorably to the +1.5% return for the Russell 2000 Index. Small cap stocks
regained significant momentum during the second quarter of 1999. The Fund's
quarterly return was +18.7% versus the +15.6% return for the Russell 2000 Index.
The Fund's average annual total return since inception was +19.4%, which
compared favorably to the +15.3% return for the Russell 2000 Index.

     Extreme undervaluation of small stocks and renewed confidence in the global
economic environment were key elements behind the strong second quarter rally
for small cap stocks. In fact, this was the first quarter in seven that the
Russell 2000 Index outperformed the Russell 1000 Index. Given the duration and
magnitude of small cap underperformance in recent years and the resulting
valuation disparity, we believe the potential exists for an extended small cap
stock rally. Our enthusiasm for smaller stocks can be illustrated by a simple
analysis of price-to-earnings ratios relative to estimated long-term growth
rates. The P/E ratio for the Fund currently stands at 32 times estimated year
2000 earnings--which is BELOW the estimated earnings growth rate of 35%. In
contrast, the P/E ratio for the S&P 500 is 26 times estimated 2000 earnings and
well ABOVE the long-term earnings growth rate of 10%.

     As of June 30th, the Fund was 96% invested in equities. The most
significant sector increases over the past year occurred in electronic
technology through purchases of Applied Micro Circuits, PMC Sierra, Galileo
Technology, and Flextronics. The financial services sector had the greatest
reduction in weighting, accomplished through sales of Imperial Credit
Industries, Life Re, Nac Re, Delphi Financial, and Community First Bank.
Electronic technology and technology services remain the heaviest weighted
sectors within the portfolio due to the robust earnings outlook for the
technology sectors.

     Although the strong returns experienced during the second quarter are
unlikely to be repeated over each of the year's remaining quarters, we believe
the Fund is in position to benefit from the improving outlook for small
capitalization investing.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Sit Small Cap Growth Fund is to maximize long-term
capital appreciation. The Fund pursues this objective by investing primarily in
the common stocks of small growth companies that have a capitalization of $2.5
billion or less at the time of purchase.

     In addition, the Fund may purchase securities convertible into common
stocks, preferred stocks and warrants. The Fund may invest in securities not
listed on a national securities exchange but generally such securities will have
an established over-the-counter market.

SIT SCIENCE AND TECHNOLOGY GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  EUGENE C. SIT, CFA
           SENIOR PORTFOLIO MANAGER

     The Sit Science and Technology Fund posted a positive return of +29.4% for
the year ended June 30, 1999. The +32.5% annualized return since inception is in
excess of broad market averages. For example, the comparable S&P 500 return for
the same eighteen-month period was +27.8%

     The Fund lagged behind the Pacific Stock Exchange Technology 100 Index
(PSE) due to the Index's disproportionate contribution from Internet securities
and the Fund's commitment to the health care sector. At the end of June, health
care stocks represented 24% of the portfolio compared to an estimated 15% health
care weight for the Index. During the past twelve months, health care holdings
have averaged approximately 33% of the portfolio. While we believe there are
many promising long-term investments within the health care sector, these stocks
have lagged behind the technology sector performance within the Fund over the
last twelve months. This relative underperformance has led to compelling
valuations for health care issues, and the Fund will continue to pursue
opportunities in this sector.

     As of June 30th, the Fund was 99% invested in equity securities, up from
96% last year. The most significant sector change was related to a shift from
the technology services sector to the electronic technology sector. Since
lingering fears of a Year 2000-related slowdown may weigh down the performance
of technology service companies, total or partial sales were made in shares of
Computer Associates, Cadence Design, Intelligroup, Peoplesoft, and Security
Dynamics. Improving fundamentals in the telecommunications and semiconductor
industries led to increased weightings within the electronic technology and
utilities sectors through the purchase of Applied Micro Circuits, Jabil Circuit,
Motorola, Nokia, PMC-Sierra, Teradyne, Vitesse Semiconduictor, and MCI Worldcom.

     Earnings for the stocks in the Fund are expected to grow +26% in 1999 and
+32% over the next five years. Despite growth rates of more than two and
one-half times the market, valuations do not appear excessive. The
price-to-earnings ratio for the Fund currently stands at 39 times 2000 earnings,
and the comparable ratio for the S&P 500 is 26 times earnings. Based on the
strong earnings growth and attractive relative valuations, we continue to be
optimistic about the outlook for companies in the Fund.


                        INVESTMENT OBJECTIVE AND STRATEGY

development, improvement, advancement and use of science and technology. During
normal market conditions, at least 80% of the Fund's total assets will be
invested in such securities. The Fund emphasizes securities of companies that
the adviser believes have potential for long-term capital growth.

SIT DEVELOPING MARKETS GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  SENIOR PORTFOLIO MANAGERS
           EUGENE C. SIT, CFA
           ANDREW B. KIM, CFA

     During the June quarter, the Sit Developing Markets Growth Fund (up +29.1%)
outperformed both the MSCI Emerging Markets Free Index (up +23.6%) and the
Lipper Emerging Markets Index (up +25.2%), reflecting the sizable positive
returns of the holdings in the Asian markets. At the end of June, equity
holdings in Asia increased to 58.1% of the net assets vs. 41.3% for the Index.
Weightings increased sharply from a year ago in Taiwan (13.2% vs. 8.4%), South
Korea (11.9% vs. 3.7%), and Singapore (10.9% vs. 6.3%) because of a continued
focus on the electronics sector's contract manufacturers.

     The Fund's 1-year return, however, was less favorable increasing +10.3%
compared with the MSCI Emerging Markets Free Index benchmark gain of +25.2% and
the Lipper Emerging Market Index return of +19.0%. The underperformance relative
to the indices was in large part the result of our underweight in Mexico, South
Korea, and Greece as well as our lack of interest rate sensitive financial and
property sector exposures in Asia early in the year. Our exposure in some
non-index countries and our high cash position also hurt performance.

     The overall Latin American weighting as of June 30th stood at 15.5% vs.
30.4% for the Index. In Latin America, the Fund's holdings continue to be
concentrated in Mexico (11.3% vs. 11.9%) based on its promising corporate
earnings outlook. The removal of near-term uncertainties over immediate U.S.
interest rate increases and higher oil prices should benefit emerging markets in
general. Specifically, Mexico should more fully benefit from strong NAFTA
economies. Brazil, however, is substantially underweight (3.0% vs. the Index's
8.7%) due to structural weakness stemming from its domestic fiscal problems.

     Emerging-Europe, Middle East and Africa holdings were underweighted at
18.4% vs. 28.3%. The Fund continued to overweight Israel (4.4% vs. 2.9%) and
underweight South Africa (2.5% vs. 11.0%). Greece was the largest weighting
(7.1% vs. 6.1%).

     Among new additions in the Fund's holdings were Korea Telecom, Development
Bank of Singapore, Hana Microelectronics in Thailand, Comverse Technology in
Israel, Philippine Long Distance Telephone in addition to Delta Dairy in Greece.

     We believe the favorable liquidity conditions in Asia should continue in
the second half, aided by the increased current account surplus, foreign direct
investment, lower interest rates and stable currencies. In addition, we look for
Japan's improving business conditions and strong currency to contribute to
Asia's economic recovery.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Sit Developing Markets Growth Fund is to maximize
long-term capital appreciation. The Fund pursues this objective by investing in
equity securities of companies located or otherwise operating in a developing
market.

     Developing markets tend to be less economically developed regions of the
world. General characteristics also include a high demand for capital
investment, a high dependence on export markets for their major industries, a
need to develop basic economic infrastructures, rapid economic growth and lower
degrees of political stability. Investors should carefully consider the risks
associated with developing markets such as currency flucuations, high
volatility, illiquidity and the possibility of political instability.

Significant accounting policies followed by the Funds are summarized below:

INVESTMENTS IN SECURITIES

Investments in securities traded on national or international securities
exchanges or on the NASDAQ National Market System are valued at the last quoted
sales price prior to the time when assets are valued; securities traded in the
over-the-counter market and listed securities for which no sale was reported on
that date are valued at the last bid price; foreign securities that are
purchased in the form of American Depository Receipts (ADRs) are valued in
United States dollars at the latest quoted price on the national securities
exchange on which the ADR is traded. When market quotations are not readily
available, securities are valued at fair value based on procedures determined in
good faith by the Board of Directors. Such fair values are determined using
prices quoted by independent brokers or pricing services. Securities maturing
more than 60 days from the valuation date are valued at the market price or
approximate market value based on current interest rates; those securities with
maturities of less than 60 days when acquired, or which subsequently are within
60 days of maturity, are valued at amortized cost, which approximates market
value.

Security transactions are accounted for on the date the securities are purchased
or sold. Securities gains and losses are calculated on the identified-cost
basis. Dividend income is recorded on the ex-dividend date or upon the receipt
of ex-dividend notification in the case of certain foreign securities. Interest,
including level-yield amortization of long-term bond premium and discount, is
recorded on the accrual basis.

ILLIQUID SECURITIES

Each Fund currently limits investments in illiquid securities to 15% of net
assets. At June 30, 1999, the Developing Markets Growth Fund and Science and
Technology Growth Fund held investments in securities deemed illiquid by the
investment adviser. The aggregate value of such securities at June 30, 1999, was
$88,660 and $34,875, representing 0.8% and 0.2% of the Fund's net assets,
respectively. Pursuant to the guidelines adopted by the Board of Directors,
certain unregistered securities are determined to be liquid and are not included
within the limitation specified above.

FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS

The market value of securities and other assets and liabilities denominated in
foreign currencies for Developing Markets Growth Fund and International Growth
Fund are translated daily into U.S. dollars at the closing rate of exchange.
Purchases and sales of securities, income and expenses are translated at the
exchange rate on the transaction date. Dividend and interest income includes
currency exchange gains (losses) realized between the accrual and payment dates
on such income. Exchange gains (losses) may also be realized between the trade
and settlement dates on security and forward contract transactions. For
securities denominated in foreign currencies, the effect of changes in foreign
exchange rates on realized and unrealized gains or losses is reflected as a
component of such gains or losses.

The Developing Markets Growth and International Growth Funds may enter into
forward foreign currency exchange contracts for operational purposes and to
protect against adverse exchange rate fluctuation. The net U.S. dollar value of
foreign currency underlying all contractual commitments held by the Funds and
the resulting unrealized appreciation or depreciation are determined using
foreign currency exchange rates from an independent pricing service. The Funds
are subject to the credit risk that the other party will not complete the
obligations of the contract.

At June 30, 1999, the Developing Markets Growth Fund had entered into a foreign
currency exchange contract that obligated the Fund to deliver currencies at
specified future dates. The unrealized appreciation and/or depreciation on these
contracts is included in the accompanying financial statements. The terms of the
open contracts are as follows:

FEDERAL TAXES

The Funds' policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of its
taxable income to shareholders. Therefore, no income tax provision is required.
Also, in order to avoid the payment of any federal excise taxes, the Funds will
distribute substantially all of their net investment income and net realized
gains on a calendar year basis.

Net investment income and net realized gains may differ for financial statement
and tax purposes. The character of distributions made during the year for net
investment income or net realized gains may also differ from its ultimate
characterization for tax purposes. Also, due to the timing of dividend
distributions, the fiscal year in which amounts are distributed may differ from
the year that the income or realized gain (losses) were recorded by the Fund.


                                                                              49

The International Growth, Mid Cap Growth, and Small Cap Growth Funds elected to
utilize equalization debits by which a portion of the costs of redemptions,
which occurred during the year ended June 30, 1998, reduced accumulated net
realized gains for tax purposes by $163,703, $427,709, and $14,112,
respectively. In addition, included in the Large Cap Growth Fund adjustment is
$10,031,752 related to an in-kind distribution.

For federal income tax purposes the Developing Markets Growth Fund has a capital
loss carryover of $3,697,984 at June 30, 1999 which, if not offset by subsequent
capital gains, will begin to expire in 2004. Also at June 30, 1999, the Small
Cap Growth, Science and Technology Growth, and Regional Growth Funds have
capital loss carryovers of $3,899,846, $332,937, and $67,482, respectively
which, if not offset by subsequent capital gains, will begin to expire in 2007.
It is unlikely that the Board of Directors will authorize a distribution of net
realized gains until the available capital loss carryovers are offset or expire.

DISTRIBUTIONS

Distributions to shareholders are recorded as of the close of business on the
record date. Such distributions are payable in cash or reinvested in additional
shares of the Funds' capital stock. Distributions from net investment income, if
any, are declared and paid quarterly for the Balanced Fund and declared and paid
annually for Regional Growth, Science and Technology Growth, Developing Markets
Growth, Small Cap Growth, International Growth, Mid Cap Growth, and Large Cap
Growth Funds. Distributions from net realized gains, if any, will be made
annually for each of the Funds.

CONCENTRATION OF INVESTMENTS

The Developing Markets Growth Fund may concentrate investments in countries with
limited or developing capital markets which may involve greater risks than
investments in more developed markets and the prices of such investments may be
volatile. The consequences of political, social or economic changes in these
markets may have disruptive effects on the market prices of the Fund's
investments and the income it generates, as well as the Fund's ability to
repatriate such amounts.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported results. Actual results could differ from those
estimates.

transaction charges relating to investing activities).

For the period November 1, 1996 through December 31, 2000 the Adviser has agreed
to limit the management fee (and, thereby, all Fund expenses, except those not

December 31, 2000, the Adviser has agreed to limit the management fee (and,

these voluntary fee waivers may be discontinued by the Adviser in its sole
discretion. During the period ended December 31, 1999, for the Mid Cap Growth,
International Growth, Regional Growth, and Science and Technology Growth Funds,
SIA voluntarily absorbed $865,657, $325,038, $14,845 and $22,008, respectively,
in expenses that were otherwise payable by the Funds.

As of June 30, 1999, the Large Cap Growth Fund, International Growth Fund, Mid
Cap Growth Fund, Small Cap Growth Fund, Regional Growth Fund, Science and
Technology Growth Fund, Developing Markets Growth Fund, and Balanced Fund had
invested $8,807,000, $3,156,000, $15,042,000, $1,491,000, $365,000, $120,000,
1,088,000, and $1,519,000, respectively, in the Sit Money Market Fund. The terms
of such transactions were identical to those of non-related entities except
that, to avoid duplicate investment advisory fees, SIA remits to each Fund an
amount equal to all fees otherwise due to them under their investment management
agreement for the assets invested in the Sit Money Market Fund.

INVESTMENT SUB-ADVISER

SIA has entered into a sub-advisory arrangement with an affiliated international
investment adviser, Sit/Kim International Investment Associates, Inc. ("SKI").
SKI provides investment research information and portfolio management service

as compensation for its services under the sub-advisory agreement, SIA pays SKI
a monthly fee of 1/12 of .75% on the first $100 million of each Fund's average
daily net assets, 1/12 of .50% on the next $100 million of average daily net
assets and 1/12 of .40% of average daily net assets in excess of $200 million.
SKI has agreed to waive any fees under the agreement to the extent that
cumulative out of pocket expenses of each Fund borne by SIA exceed the
cumulative fees received by SIA pursuant to each Fund's investment management
agreement. In accordance with the Agreement, fees of $681,189 were paid or
payable to SKI for the year ended June 30, 1999.

(1)  Total investment return is based on the change in net asset value of a
     share during the period and assumes reinvestment of distributions at net
     asset value.

(2)  Percentages for period ended June 30, 1998 are adjusted to an annual rate.
     Total Fund expenses are contractually limited to 1.50% of average daily net
     assets. However, during the periods ended June 30, 1999 and 1998, the
     investment adviser voluntarily absorbed $22,008 and $4,655, respectively,
     in expenses that were otherwise payable by the Fund. Had the fund incurred
     these expenses, the ratio of expenses to average daily net assets would
     have been 1.25% for the periods ended June 30, 1999 and 1998, and the ratio
     of net investment income (loss) to average daily net assets would have been
     (0.97%) and (0.46%), respectively.

The Board of Directors and Shareholders
Sit Large Cap Growth Fund, Inc.

Sit Mutual Funds, Inc.:

     We have audited the accompanying statements of assets and liabilities,
including the schedules of portfolios of investments in securities of Sit
Balanced Fund (a series of Sit Mutual Funds, Inc.), Sit Large Cap Growth Fund,
Inc., Sit Regional Growth Fund (a series of Sit Mutual Funds, Inc.), Sit Mid Cap
Growth Fund, Inc., Sit International Growth Fund (a series of Sit Mutual Funds,
Inc.), Sit Small Cap Growth Fund (a series of Sit Mutual Funds, Inc.), Sit
Science and Technology Growth Fund (a series of Sit Mutual Funds, Inc.), and Sit
Developing Markets Growth Fund (a series of Sit Mutual Funds, Inc.), as of June
30, 1999; the related statements of operations for the period ended June 30,
1999; the statements of changes in net assets for each of the periods in the
two-year period ended June 30, 1999; and the financial highlights as presented
in note 4 to the financial statements. These financial statements and the
financial highlights are the responsibility of the Funds' management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform our audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased and sold but not received or delivered, we
request confirmations from brokers and where replies are not received, we carry
out other appropriate auditing procedures. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements and the financial highlights
referred to above present fairly, in all material respects, the financial
position of Sit Balanced Fund, Sit Large Cap Growth Fund, Sit Regional Growth
Fund, Sit Mid Cap Growth Fund, Sit International Growth Fund, Sit Small Cap
Growth Fund, Sit Science and Technology Growth Fund, and Sit Developing Markets
Growth Fund as of June 30, 1999 and the results of their operations, the changes
in their net assets, and the financial highlights for the periods stated in the
first paragraph above, in conformity with generally accepted accounting
principles.

       A SERIES OF SIT MUTUAL FUNDS, INC., BY AND IN EXCHANGE FOR SHARES
                       OF SIT LARGE CAP GROWTH FUND, INC.

         This Statement of Additional Information relates to the proposed
Agreement and Plan of Reorganization providing for (a) the acquisition of
substantially all of the assets and the assumption of all liabilities of Sit
Regional Growth Fund (the "Acquired Fund"), a series of Sit Mutual Funds, Inc.,
in exchange for shares of common stock of Sit Large Cap Growth Fund, Inc. (the
"Acquiring Fund") having an aggregate net asset value equal to the aggregate
value of the assets acquired (less the liabilities assumed) of the Acquired Fund
and (b) the liquidation of the Acquired Fund and the pro rata distribution of
the Acquiring Fund shares to Acquired Fund shareholders.

         This Statement of Additional Information consists of this cover page
and the following documents, which are incorporated by reference herein:

         1.       The Statement of Additional Information dated November 1, 1999
                  of the Acquiring Fund and the Acquired Fund.

                  Fund included in the Sit Stock Funds Semi-Annual Report for

         No additional financial statements are required by Form N-14, Item 14
because the net asset value of the Acquired Fund did not exceed 10% of the net
asset value of the Acquiring Fund as of March 31, 2000.

Under exceptional economic or market conditions abroad, the Fund may temporarily
invest all or a major portion of its assets in United States government
obligations or high grade debt obligations of companies incorporated in or
having their principal activities in the United States.

COUNTRIES IN WHICH THE DEVELOPING MARKETS GROWTH FUND MIGHT INVEST
- --------------------------------------------------------------------------------

The Fund defines "developing markets" as those countries determined by the
Sub-Adviser to have developing or emerging markets or economies. Such countries
will generally be defined as "emerging stock markets" by the International
Finance Corporation, demonstrate low- to middle-income economies according to
the International Bank for Reconstruction and Development (the World Bank), or
be listed in World Bank publications as developing. Countries currently not
considered as having "developing markets" presently include: Australia, Austria,
Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the
Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland, the United
Kingdom, and the United States.

The countries in which the Fund may seek to invest include those listed below
and, unless otherwise prohibited herein, the countries listed as potential
investments for the International Growth Fund as well. The Fund is not obligated
and may not invest in all the countries listed; moreover the Fund may invest in
countries other than those listed below, when such investments are consistent
with the Fund's investment objectives and policies. The Fund will also not seek
to diversify investments among geographic regions or levels of economic
development in any particular country.

INTERNATIONAL RISK CONSIDERATIONS
- --------------------------------------------------------------------------------

Investors should consider carefully the substantial risks involved in securities
of companies and governments of foreign nations, which are in addition to the
usual risks inherent in domestic investments. There may be less publicly
available information about foreign companies comparable to the reports and
ratings published regarding companies in the United States. Foreign companies
are not generally subject to uniform accounting, auditing and financial
reporting standards, and auditing practices and requirements may not be
comparable to those applicable to United States companies. Many foreign markets
have substantially less volume than either the established domestic securities
exchanges or the OTC markets. Securities of some foreign companies are less
liquid and more volatile than securities of comparable United States companies.
Commission rates in foreign countries, which may be fixed rather than subject to
negotiation as in the United States, are likely to be higher. In many foreign
countries there is less government supervision and regulation of securities
exchanges, brokers and listed companies than in the United States and capital
requirements for brokerage firms are generally


                                       9
<PAGE>


lower. Settlement of transactions in foreign securities may, in some instances,
be subject to delays and related administrative uncertainties.

Investments in companies domiciled in developing market countries may be subject
to potentially higher risks than investments in developed countries. These risks
include (i) volatile social, political and economic conditions; (ii) the small
current size of the markets for such securities and the currently low or
nonexistent volume of trading, which result in a lack of liquidity and in
greater price volatility; (iii) the existence of national policies which may
restrict the Funds' investment opportunities, including restrictions on
investment in issuers or industries deemed sensitive to national interests; (iv)
foreign taxation; (v) the absence of developed structures governing private or
foreign investment or allowing for judicial redress for injury to private
property; (vi) the absence, until recently in certain developing market
countries, of a capital market structure or market-oriented economy; and (vii)
the possibility that recent favorable economic developments in certain
developing market countries may be slowed or reversed by unanticipated political
or social events in such countries.

The Funds endeavor to buy and sell foreign currencies on favorable terms. Some
price spread on currency exchange (to cover service charges) may be incurred,
particularly when the Funds change investments from one country to another or
when proceeds for the sale of shares in U.S. dollars are used for the purchase
of securities in foreign countries. Also, some countries may adopt policies
which would prevent the Funds from repatriating invested capital and dividends,
withhold portions of interest and dividends at the source, or impose other
taxes, with respect to the Funds' investments in securities of issuers of that
country. There also is the possibility of expropriation, nationalization,
confiscatory or other taxation, foreign exchange controls (which may include
suspension of the ability to transfer currency from a given country), default in
foreign government securities, political or social instability, or diplomatic
developments that could adversely affect investments in securities of issuers in
those nations.

The Funds may be affected either favorably or unfavorably by fluctuations in the
relative rates of exchange between the currencies of different nations, exchange
control regulations and indigenous economic and political developments.

While transactions in forward currency contracts, options, futures contracts and
options on futures contracts (i.e., "hedging positions") may reduce certain
risks, such transactions themselves entail certain other risks. Thus, while the
Funds may benefit from the use of hedging positions, unanticipated changes in
interest rates, securities prices or currency exchange rates may result in a
poorer overall performance for the Funds than if they had not entered into any
hedging positions. In the event of an imperfect correlation between a hedging
position and portfolio position which is intended to be protected, the desired
protection may not be obtained and the Funds may be exposed to risk of financial
loss.

Perfect correlation between the Funds' hedging positions and portfolio positions
may be difficult to achieve because hedging instruments in most developing
market countries are not yet available. In addition, it is not possible to hedge
fully or perfectly against currency fluctuations affecting the value of
securities denominated in foreign currencies because the value of such
securities is likely to fluctuate as a result of independent factors not related
to currency fluctuations.

INVESTMENT AND REPATRIATION RESTRICTIONS
- --------------------------------------------------------------------------------
Several of the countries in which the Funds may invest restrict, to varying
degrees, foreign investments in their securities markets. Governmental and
private restrictions take a variety of forms, including (i) limitations on the
amount of funds that may be invested into or repatriated from the country
(including limitations on repatriation of investment income and capital gains),
(ii) prohibitions or substantial restrictions on foreign investment in certain
industries or market sectors, such as defense, energy and transportation, (iii)
restrictions (whether contained in the charter of an individual company or
mandated by the government) on the percentage of securities of a single issuer
which may be owned by a foreign investor, (iv) limitations on the types of
securities which a foreign investor may purchase and (v) restrictions on a
foreign investor's right to invest in companies whose securities are not
publicly traded. In some circumstances, these restrictions may limit or preclude
investment in certain countries and the Funds intend to invest only through the
purchase of shares of investment funds organized under the laws of such
countries.

The return on the Funds' investments in investment companies will be reduced by
the operating expenses, including investment advisory and administrative fees,
of such companies. The Funds' investment in an investment company may require
the payment of a premium above the net asset value of the investment company's
shares, and the market price of the investment company thereafter may decline
without any change in the value of the investment company's assets. The


                                       10
<PAGE>


Funds, however, will not invest in any investment company or trust unless it is
believed that the potential benefits of such investment are sufficient to
warrant the payment of any such premium.

ADDITIONAL INVESTMENT OBJECTIVES, POLICIES & RISKS
- --------------------------------------------------------------------------------

CONVERTIBLE SECURITIES
- --------------------------------------------------------------------------------
Each of the Funds may purchase securities convertible into common stocks,
preferred stocks and warrants.

COMMERCIAL PAPER
- --------------------------------------------------------------------------------
Short-term debt instruments purchased by the Funds consist of commercial paper
(including variable amount master demand notes), which refers to short-term,
unsecured promissory notes issued by corporations to finance short-term credit
needs. Commercial paper is usually sold on a discount basis and has a maturity
at the time of issuance not exceeding nine months. Variable amount master demand
notes are demand obligations that permit the investment of fluctuating amounts
at varying market rates of interest pursuant to arrangements between the issuer
and a commercial bank acting as agent for the payees of such notes, whereby both
parties have the right to vary the amount of the outstanding indebtedness of the
notes.

The Balanced Fund may invest in commercial paper obligations issued by domestic
and foreign entities which, at the time of their purchase, are rated in the
highest rating category assigned by Moody's, S&P, Duff and Phelps, Inc. or Fitch
Investors Service, Inc. or, if not rated, are issued or guaranteed by companies
with an unsecured debt issue currently outstanding rated A or better by Moody's
or S&P. The Fund may also invest in participation interests in loans extended by
banks or other financial institutions to such companies, and other domestic
corporate obligations such as publicly traded bonds, debentures and notes
(including variable amount master demand notes) rated in the highest category by
the aforementioned rating services.

OBLIGATIONS OF, OR GUARANTEED BY, THE UNITED STATES GOVERNMENT, ITS AGENCIES OR
INSTRUMENTALITIES
- --------------------------------------------------------------------------------
Securities issued or guaranteed by the United States include a variety of
Treasury securities, which differ only in their interest rates, maturities and
dates of issuance. Treasury bills have a maturity of one year or less. Treasury
notes have maturities of one to ten years and Treasury bonds generally have
maturities of greater than ten years at the date of issuance.

Securities issued and or guaranteed by agencies of the U.S. government and
various instrumentalities which have been established or sponsored by the U.S.
government may or may not be backed by the "full faith and credit" of the United
States. In the case of securities not backed by the full faith and credit of the
United States, the investor must look principally to the agency issuing or
guaranteeing the obligation for ultimate repayment and may not be able to assert
a claim against the United States itself in the event the agency or
instrumentality does not meet its commitment.

Some of the government agencies which issue or guarantee securities are the
Department of Housing and Urban Development, the Department of Health and Human
Services, the Government National Mortgage Association, the Farmers Home
Administration, the Department of Transportation, the Department of Defense and
the Department of Commerce. Instrumentalities which issue or guarantee
securities include the Export-Import Bank, the Federal Farm Credit System,
Federal Land Banks, the Federal Intermediate Credit Bank, the Bank for
Cooperatives, Federal Home Loan Banks, the Federal National Mortgage Association
and the Federal Home Loan Mortgage Corporation.

OBLIGATIONS OF BANKS
- --------------------------------------------------------------------------------
Bank money instruments in which the Funds may invest include certificates of
deposit, including variable rate certificates of deposit, bankers' acceptances
and time deposits. "Bank" includes commercial banks, savings banks and savings
and loan associations. Certificates of deposit are generally short-term,
interest-bearing negotiable certificates issued by commercial banks or savings
and loan associations against funds deposited in the issuing institution.
Variable rate certificates of deposit are certificates of deposit on which the
interest rate is periodically adjusted prior to their stated maturity, usually
at 30, 90 or 180 day intervals ("coupon dates"), based upon a specified market
rate, which is tied to the then prevailing certificate of deposit rate, with
some premium paid because of the longer final maturity date of the variable rate
certificate of deposit. As a result of these adjustments, the interest rate on
these obligations may be increased or decreased periodically. Variable rate
certificates of deposit normally carry a higher interest rate than fixed rate
certificates of deposit with shorter maturities, because the bank issuing the
variable rate certificate of deposit pays the investor a premium as the bank has
the use of the investor's money for a longer period of time. Variable rate
certificates of deposit can be sold in the secondary market. In


                                       11
<PAGE>


addition, frequently banks or dealers sell variable rate certificates of deposit
and simultaneously agree, either formally or informally, to repurchase such
certificates, at the option of the purchaser of the certificate, at par on the
coupon dates. In connection with the Fund's purchase of variable rate certifies
of deposit, it may enter into formal or informal agreements with banks or
dealers allowing the Fund to resell the certificates to the bank or dealer, at
the Fund's option. If the agreement to repurchase is informal, there can be no
assurance that the Fund would always be able to resell such certificates. Before
entering into any such transactions governed by formal agreements, however, the
Fund will comply with the provisions of SEC Release 10666 which generally
provides that the repurchase agreement must be fully collateralized. With
respect to variable rate certificates of deposit maturing in 180 days or less
from the time of purchase with interest rates adjusted on a monthly cycle, the
Fund uses the period remaining until the next rate adjustment date for purposes
of determining the average weighted maturity of its portfolio. With respect to
all variable rate instruments not meeting the foregoing criteria, the Fund uses
the remaining period to maturity for purposes of determining the average
weighted maturity of its portfolio until such time as the Securities and
Exchange Commission has determined otherwise.

A banker's acceptance is a time draft drawn on a commercial bank by a borrower
usually in connection with an international commercial transaction (to finance
the import, export, transfer or storage of goods). The borrower is liable for
payment as well as the bank, which unconditionally guarantees to pay the draft
at its face amount on the maturity date. Most acceptances have maturities of six
months or less and are traded in secondary markets prior to maturity.

Both domestic banks and foreign branches of domestic banks are subject to
extensive, but different, governmental regulations which may limit both the
amount and types of loans which may be made and interest rates which may be
charged. In addition, the profitability of the banking industry is largely
dependent upon the availability and cost of funds for the purpose of financing
lending operations under prevailing short-term debt conditions. General economic
conditions, as well as exposure to credit losses arising from possible financial
difficulties of borrowers, also play an important part in the operations of the
banking industry.

As a result of federal and state laws and regulations, domestic banks are, among
other things, generally required to maintain specified levels of reserves,
limited in the amount which they can loan to a single borrower, and are subject
to other regulations designed to promote financial soundness. Since the
portfolio may contain securities of foreign banks and foreign branches of
domestic banks, the Fund may be subject to additional investment risks that are
different in some respects from those incurred by a fund that invests only in
debt obligations of domestic banks.

The Fund only purchases certificates of deposit from savings and loan
institutions which are members of the Federal Home Loan Bank and are insured by
the Federal Savings and Loan Insurance Corporation. Such savings and loan
associations are subject to regulation and examination. Unlike most savings
accounts, certificates of deposit held by the Fund do not benefit materially
from insurance either from the Federal Deposit Insurance Corporation or the
Federal Savings and Loan Insurance Corporation. Certificates of deposit of
foreign branches of domestic banks are not covered by such insurance and
certificates of deposit of domestic banks purchased by the Fund are generally in
denominations far in excess of the dollar limitations on insurance coverage.

INTERNATIONAL BANK OBLIGATIONS. For the purposes of the Developing Markets
Growth Fund's and International Growth Fund's investment policies with respect
to bank obligations, obligations of foreign branches of U.S. banks and of
foreign banks may be obligations of the parent bank in addition to the issuing
bank, or may be limited by the terms of a specific obligation and by government
regulation. As with investment in non-U.S. securities in general, investments in
the obligations of foreign branches of U.S. banks and of foreign banks may
subject the Funds to investment risks that are different in some respects from
those of investments in obligations of domestic issuers. Although the Funds will
typically acquire obligations issued and supported by the credit of U.S. or
foreign banks having total assets at the time of purchase in excess of $1
billion, this $1 billion figure is not a fundamental investment policy or
restriction of the Fund. For the purposes of calculation with respect to the $1
billion figure, the assets of a bank will be deemed to include the assets of its
U.S. and non-U.S. branches.

DEPOSITORY RECEIPTS
- --------------------------------------------------------------------------------
The Funds may hold securities of foreign issuers in the form of American
Depository Receipts ("ADRs"), European Depository Receipts ("EDRs"), Government
Depository Receipts ("GDRs") and other similar global instruments available in
developing markets, or other securities convertible into securities of eligible
issuers. These securities may not necessarily be


                                       12
<PAGE>


denominated in the same currency as the securities for which they may be
exchanged. Generally, ADRs in registered form are designed for use in United
States securities markets, and EDRs and other similar global instruments in
bearer form are designed for use in European securities markets. For purposes of
the Fund's investment policies, the Fund's investment in ADRs, EDRs, and similar
instruments will be deemed to be investments in the equity securities
representing securities of foreign issuers into which they may be converted.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS
- --------------------------------------------------------------------------------
The Developing Markets Growth Fund and International Growth Fund may enter into
forward currency contracts to attempt to minimize the risk to the Funds from
adverse changes in the relationship between the U.S. dollar and foreign
currencies. A forward currency contract is an obligation to purchase or sell a
specific currency for an agreed upon price at a future date which is
individually negotiated and privately traded by currency traders and their
customers. The Funds may enter into a forward currency contract, for example,
when it enters into a contract for the purchase or sale of a security
denominated in a foreign currency or is expecting a dividend or interest payment
in order to "lock in" the U.S. dollar price of the security or dividend or
interest payment. In addition, when the Funds believe that a foreign currency or
currencies may suffer a substantial decline against the U.S. dollar, it may
enter into a forward currency contract to sell an amount of a foreign currency
approximating the value of some or all of the Funds' portfolio securities
denominated in such foreign currency or related currencies that the Adviser
feels demonstrate correlation in exchange rate movements (such a practice is
called "crosshedging"), or when the Funds believe that the U.S. dollar may
suffer a substantial decline against a foreign currency or currencies, it may
enter into a forward contract to buy a foreign currency for a fixed dollar
amount. In connection with the Funds' forward contract transactions, an amount
of the Funds' assets equal to the amount of the Fund's commitment will be held
aside or segregated to be used to pay for the commitment. Accordingly, the Funds
will always have cash, cash equivalents or high quality debt securities
denominated in the appropriate currency available in an amount sufficient to
cover any commitments under these contracts. Segregated assets used to cover
forward currency contracts will be marked to market on a daily basis. While
these contracts are not presently regulated by the Commodity Futures Trading
Commission ("CFTC"), the CFTC may in the future regulate forward currency
contracts. In such event, the Funds' ability to utilize forward currency
contracts in the manner set forth above may be restricted. Forward currency
contracts may limit potential gain from a positive change in the relationship
between the U.S. dollar and foreign currencies. Unanticipated changes in
currency prices may result in poorer overall performance by the Funds than if it
had not engaged in such contracts. The Funds will generally not enter into a
forward foreign currency exchange contract with a term greater than one year.

OPTIONS - PUTS AND CALLS
- --------------------------------------------------------------------------------
The Funds may purchase exchange traded put and call options on debt securities
up to 5% of its net assets for the purpose of hedging. A put option (sometimes
called a standby commitment) gives the purchaser of the option, in return for a
premium paid, the right to sell the underlying security at a specified price
during the term of the option. The writer of the put option receives the premium
and has the obligation to buy the underlying securities upon exercise at the
exercise price during the option period. A call option (sometimes called a
reverse standby commitment) gives the purchaser of the option, in return for a
premium, the right to buy the security underlying the option at a specified
exercise price at any time during the term of the option. The writer of the call
option receives the premium and has the obligation at the exercise of the
option, to deliver the underlying security against payment of the exercise price
during the option period. A principal risk of standby commitments is that the
writer of a commitment may default on its obligation to repurchase or deliver
the securities.

WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES
- --------------------------------------------------------------------------------
The Funds may purchase securities on a "when-issued" basis and may purchase or
sell securities on a "forward commitment" basis. When such transactions are
negotiated, the price is fixed at the time the commitment is made, but delivery
and payment for the securities take place at a later date, which can be a month
or more after the date of the transaction. The Funds will not accrue income on
securities purchased on a forward commitment basis prior to their stated
delivery date. At the time the Funds make the commitment to purchase securities
on a when-issued or forward commitment basis, they will record the transaction
and thereafter reflect the value of such securities in determining their net
asset value. At the time the Funds enter into a transaction on a when-issued or
forward commitment basis, a segregated account consisting of cash and liquid
securities equal to the value of the when-issued or forward commitment
securities will be established and maintained with the custodian and will be
marked to the market daily. On the delivery date, the Funds will meet their
obligations from securities that are then maturing or sales of the securities
held in the segregated asset account and/or from then available cash flow. If
the Funds dispose of the right to acquire a when-issued


                                       13
<PAGE>


security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it can incur a gain or loss due to market
fluctuation.

There is always a risk that the securities may not be delivered and that the
Fund may incur a loss or will have lost the opportunity to invest the amount set
aside for such transaction in the segregated asset account. Settlements in the
ordinary course of business, which may take substantially more than five
business days for non-U.S. securities, are not treated by the Fund as
when-issued or forward commitment transactions and, accordingly, are not subject
to the foregoing limitations even though some of the risks described above may
be present in such transactions.

REPURCHASE AGREEMENTS
- --------------------------------------------------------------------------------
Each Fund is permitted to invest in repurchase agreements. A repurchase
agreement is a contract by which the Fund acquires the security ("collateral")
subject to the obligation of the seller to repurchase the security at a fixed
price and date (within seven days). A repurchase agreement may be construed as a
loan pursuant to the 1940 Act. The Funds may enter into repurchase agreements
with respect to any securities which it may acquire consistent with its
investment policies and restrictions. The Funds' custodian will hold the
securities underlying any repurchase agreement in a segregated account. In
investing in repurchase agreements, the Funds' risk is limited to the ability of
the seller to pay the agreed-upon price at the maturity of the repurchase
agreement. In the opinion of the Adviser, such risk is not material, since in
the event of default, barring extraordinary circumstances, the Funds would be
entitled to sell the underlying securities or otherwise receive adequate
protection under federal bankruptcy laws for its interest in such securities.
However, to the extent that proceeds from any sale upon a default are less than
the repurchase price, the Funds could suffer a loss. In addition, the Funds may
incur certain delays in obtaining direct ownership of the collateral. The
Adviser will continually monitor the value of the underlying securities to
ensure that their value always equals or exceeds the repurchase price. The
Adviser will submit a list of recommended issuers of repurchase agreements and
other short-term securities which it has reviewed for credit worthiness to the
Funds' directors at least quarterly for their approval.

FUTURES CONTRACTS, OPTIONS ON FUTURES CONTRACTS, AND SWAP AGREEMENTS
- --------------------------------------------------------------------------------
The Balanced Fund, Developing Markets Growth Fund and International Growth Fund
may invest in interest rate futures contracts, index futures contracts and may
buy options on such contracts for the purpose of hedging its portfolio of fixed
income securities (and not for speculative purposes) against the adverse effects
of anticipated movements in interest rates. As a result of entering into futures
contracts, no more than 5% of a Fund's net assets may be committed to margin.

DESCRIPTION OF FUTURES CONTRACTS. A futures contract sale creates an obligation
by a Fund, as seller, to deliver the type of financial instrument called for in
the contract at a specified future time for a stated price. A futures contract
purchase creates an obligation by the Fund, as purchaser, to take delivery of
the underlying financial instrument at a specified future time for a stated
price. The specific securities delivered or taken, respectively, at settlement
date, are not determined until at or near that date. The determination is made
in accordance with the rules of the exchange on which the futures contract sale
or purchase was made.

Although futures contracts by their terms call for actual delivery or acceptance
of securities, in most cases the contracts are closed out before the settlement
date without the making or taking of delivery. Closing out a futures contract
sale is effected by purchasing a futures contract for the same aggregate amount
of the specific type of financial instrument and the same delivery date. If the
price of the initial sale of the futures contract exceeds the price of the
offsetting purchase, the Fund is paid the difference and realizes a gain. If the
price of the offsetting purchase exceeds the price of the initial sale, the Fund
pays the difference and realizes a loss. Similarly, the closing out of a futures
contract purchase is effected by the Fund entering into a futures contract sale.
If the offsetting sale price exceeds the purchase price, the Fund realizes a
gain, and if the purchase price exceeds the offsetting sale price, the Fund
realizes a loss.

The Fund is required to maintain margin deposits with brokerage firms through
which it enters into futures contracts. Margin balances will be adjusted at
least weekly to reflect unrealized gains and losses on open contracts. In
addition, the Fund will pay a commission on each contract, including offsetting
transactions.

Futures contracts are traded only on commodity exchanges--known as "contract
markets"--approved for such trading by the Commodity Futures Trading Commission
("CFTC"), and must be executed through a futures commission merchant or
brokerage firm which is a member of the relevant contract market. The CFTC
regulates trading activity on the exchanges


                                       14
<PAGE>


pursuant to the Commodity Exchange Act. The principal exchanges are the Chicago
Board of Trade, the Chicago Mercantile Exchange and the New York Futures
Exchange. Each exchange guarantees performance under contract provisions through
a clearing corporation, a nonprofit organization managed by the exchange
membership. The staff of the CFTC has indicated that an entity such as the Fund
would not be a "pool" if it traded commodity futures contracts solely for
hedging purposes and not for speculation. Furthermore, the Fund is restricted to
no more than 5% of its net assets being committed to margin on futures contracts
and premiums for options on futures contracts, and therefore will not operate as
a "pool" as that term is defined by the CFTC.

The Funds may use interest rate futures solely as a defense or hedge against
anticipated interest rate changes and not for speculation. The Funds presently
could accomplish a similar result to that which it hopes to achieve through the
use of futures contracts by selling debt securities with long maturities and
investing in debt securities with short maturities when interest rates are
expected to increase, or conversely, selling short-term debt securities and
investing in long-term debt securities when interest rates are expected to
decline. However, because of the liquidity that is often available in the
futures market, such protection is more likely to be achieved, perhaps at a
lower cost and without changing the rate of interest being earned by the Funds,
through using futures contracts.

RISKS IN FUTURES CONTRACTS. One risk in employing futures contracts to protect
against cash market price volatility is the prospect that futures prices will
correlate imperfectly with the behavior of cash prices. The ordinary spreads
between prices in the cash and futures markets, due to differences in the
natures of those markets, are subject to distortions. First, all participants in
the futures market are subject to margin deposit and maintenance requirements.
Rather than meeting additional margin deposit requirements, investors may close
futures contracts through offsetting transactions which could distort the normal
relationship between the cash and futures markets. Second, the liquidity of the
futures market depends on participants entering into offsetting transactions
rather than making or taking delivery. To the extent participants decide to make
or take delivery, liquidity in the futures market could be reduced, thus
producing distortion. Third, from the point of view of speculators the deposit
requirements in the futures market are less onerous than margin requirements in
the securities market. Therefore, increased participation by speculators in the
futures market may cause temporary price distortions. Due to the possibility of
distortion, a correct forecast of general interest trends by the Adviser may
still not result in a successful transaction.

Another risk is that the Adviser would be incorrect in its expectation as to the
extent of various interest rate movements (anticipated securities prices and
foreign currency exchange rates for the Developing Markets Growth Fund and
International Growth Fund) or the time span within which the movements take
place and other economic factors. Closing out an interest rate futures contract
purchase at a loss because of higher interest rates will generally have one or
two consequences depending on whether, at the time of closing out, the "yield
curve" is normal (long-term rates exceeding short-term). If the yield curve is
normal, it is possible that the Fund will still be engaged in a program of
buying long-term securities. Thus, closing out the futures contract purchase at
a loss will reduce the benefit of the reduced price of the securities purchased.
If the yield curve is inverted, it is possible that the Fund will retain its
investments in short-term securities earmarked for purchase of longer term
securities. Thus, closing out of a loss will reduce the benefit of the
incremental income that the Fund will experience by virtue of the high
short-term rates. Although futures contracts are traded only on commodity
exchanges, there can be no assurance that a liquid secondary market will exist
for any particular future, and theoretically losses from investing in futures
transactions are potentially unlimited.

RISKS OF OPTIONS. The use of options and options on interest rate futures
contracts also involves additional risk. Compared to the purchase or sale of
futures contracts, the purchase of call or put options and options on futures
contracts involves less potential risk to a Fund because the maximum amount at
risk is the premium paid for the options (plus transaction costs).

The effective use of options strategies is dependent, among other things, upon
the Fund's ability to terminate options positions at a time when the Adviser
deems it desirable to do so. Although the Fund will enter into an option
position only if the Adviser believes that a liquid secondary market exists for
such option, there is no assurance that the Fund will be able to effect closing
transactions at any particular time or at an acceptable price. The Fund's
transactions involving options on futures contracts will be conducted only on
recognized exchanges.

Although the Funds will generally purchase only those options for which there
appears to be an active secondary market, there can be no assurance that a
liquid secondary market on an exchange will exist for any particular option, or
at any


                                       15
<PAGE>


particular time. For some options no secondary market on an exchange may exist.
In such event, it might not be possible to effect closing transactions in
particular options, with the result that the Funds would have to exercise its
options in order to realize any profit and would incur transaction costs upon
the purchase or sale of underlying securities.

Secondary markets on an exchange may not exist or may not be liquid for a
variety of reasons including: (i) insufficient trading interest in certain
options; (ii) restrictions on opening transactions or closing transactions
imposed by an exchange; (iii) trading halts, suspension or other restrictions
may be imposed with respect to particular classes or series of options; (iv)
unusual or unforeseen circumstances which interrupt normal operations on an
exchange; (v) inadequate facilities of an exchange or the Options Clearing
Corporation to handle current trading volume at all times; or (vi)
discontinuance in the future by one or more exchanges for economic or other
reasons, of trading of options (or of a particular class or series of options),
in which event the secondary market on that exchange (or in that class or series
of options) would cease to exist, although outstanding options on that exchange
that had been issued by the Options Clearing Corporation as a result of trades
on that exchange would continue to be exercisable in accordance with their
terms.

PURCHASE OF PUT OPTIONS ON INTEREST RATE FUTURES CONTRACTS. The Balanced Fund,
Developing Markets Growth Fund, and International Growth Fund may purchase put
options on interest rate futures contracts if the Adviser anticipates a rise in
interest rates. Because the value of an interest rate or municipal bond index
futures contract moves inversely in relation to changes in interest rates, a put
option on such a contract becomes more valuable as interest rates rise. By
purchasing put options on futures contracts at a time when the Adviser expects
interest rates to rise, the Fund will seek to realize a profit to offset the
loss in value of its portfolio securities.

PURCHASE OF CALL OPTIONS ON INTEREST RATE FUTURES CONTRACTS. The Balanced Fund,
Developing Markets Growth Fund, and International Growth Fund may purchase call
options on interest rate futures contracts if the Adviser anticipates a decline
in interest rates. The purchase of a call option on an interest rate of
municipal bond index futures contract represents a means of obtaining temporary
exposure to market appreciation at limited risk. Because the value of an
interest rate or municipal bond index futures contract moves inversely in
relation to changes to interest rates, a call option on such a contract becomes
more valuable as interest rates decline. The Fund will purchase a call option on
a futures contract to hedge against a decline in interest rates in a market
advance when the Fund is holding cash. The Fund can take advantage of the
anticipated rise in the value of long-term securities without actually buying
them until the market is stabilized. At that time, the options can be liquidated
and the Fund's cash can be used to buy long-term securities.

The Funds expect that new types of securities, futures contracts, options
thereon, and put and call options on securities and indices may be developed in
the future. As new types of instruments are developed and offered to investors,
the Adviser will be permitted to invest in them provided that the Adviser
believes their quality is equivalent to the Fund's quality standards.

SWAP AGREEMENTS. Swap agreements are two party contracts entered into primarily
by institutional investors in which two parties agree to exchange the returns
(or differential rates of return) earned or realized on particular predetermined
investments or instruments.

The Funds may enter into swap agreements for purposes of attempting to obtain a
particular investment return at a lower cost to the Funds than if the Funds had
invested directly in an instrument that provided that desired return. Each Fund
bears the risk of default by its swap counterpart and may not be able to
terminate its obligations under the agreement when it is most advantageous to do
so. In addition, certain tax aspects of swap agreements are not entirely clear
and their use, therefore, may be limited by the requirements relating to the
qualification of a Fund as a regulated investment company under the Internal
Revenue Code of 1986, as amended (the "Code").

ADDITIONAL FIXED-INCOME SECURITIES IN WHICH THE BALANCED FUND MAY INVEST
- --------------------------------------------------------------------------------

MORTGAGE-BACKED SECURITIES. The mortgage-backed securities in which the Balanced
Fund invests provide funds for mortgage loans made to residential home buyers.
These include securities which represent interests in pools of mortgage loans
made by lenders such as savings and loan institutions, mortgage banks,
commercial banks and insurance companies. Pools of mortgage loans are assembled
for sale to investors such as the Fund by various private, governmental and
government-related organizations.


                                       16
<PAGE>


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.
Mortgage-backed securities provide monthly payments which consist of both
interest and principal payments to the investor. In effect, these payments are a
"pass-through" of the monthly payments made by the individual borrowers on their
residential mortgage loans, net of any fees paid to the issuer, servicer, or
guarantor of such securities. Additional payments are caused by repayments of
principal resulting from the sale of the underlying residential property,
refinancing or foreclosure, net of fees or costs which may be incurred. Some
mortgage-backed securities, i.e., GNMA's, are described as "modified
pass-through." These securities entitle the holders to receive all interest and
principal payments owed on the mortgages in the pool, net of certain fees,
regardless of whether or not the mortgagors actually make the payments.

The principal government guarantor of mortgage-backed securities is the
Government National Mortgage Association ("GNMA"). GNMA is a wholly-owned U.S.
government corporation within the Department of Housing and Urban Development.
GNMA is authorized to issue mortgage pass-through securities and guarantee, with
the full faith and credit of the U.S. government, the timely payment of
principal and interest on loans originated by approved institutions and backed
by pools of FHA-insured or VA-guaranteed mortgages.

The Federal Home Loan Mortgage Corporation ("FHLMC") also pools mortgage loans
and issues pass-through securities. FHLMC is a corporate instrumentality of the
U.S. government and was created by Congress in 1970 for the purpose of
increasing the availability of mortgage credit for residential housing. Its
stock is owned by the twelve Federal Home Loan Banks. FHLMC issues Participation
Certificates ("PC's") which represent interest in mortgages from FHLMC's
national portfolio. FHLMC guarantees the timely payment of interest and ultimate
collection of principal, however, PC's are not backed by the full faith and
credit of the U.S. government.

The Federal National Mortgage Association ("FNMA") is a government sponsored
corporation owned entirely by private stockholders. It is subject to general
regulation by the Secretary of Housing and Urban Development. FNMA purchases
residential mortgages from a list of approved seller/services which include
state and federally-chartered savings and loan associations, mutual savings
banks, commercial banks and credit unions and mortgage banks. Pass-through
securities issued by FNMA are guaranteed as to timely payment of principal and
interest by FNMA, but are not backed by the full faith and credit of the U.S.
government.

The Federal Housing Administration ("FHA") was established by Congress in 1934
under the National Housing Act. A major purpose of the Act was to encourage the
flow of private capital into residential financing on a protected basis. FHA is
authorized to insure mortgage loans, primarily those related to residential
housing. FHA does not make loans and does not plan or build housing. FHA Project
Pools are pass-through securities representing undivided interests in pools of
FHA-insured multi-family project mortgage loans.

The Fund may purchase securities which are insured but not issued or guaranteed
by the U.S. government, its agencies or instrumentalities. An example of such a
security is a housing revenue bond (the interest on which is subject to federal
taxation) issued by a state and insured by an FHA mortgage loan. The Fund has
not purchased this type of security and has no current intent to do so. This
type of mortgage is insured by FHA pursuant to the provisions of Section
221(d)(4) of the National Housing Act of 1934, as amended. After a mortgagee
files a claim for insurance benefits, FHA will pay insurance benefits up to 100%
of the unpaid principal amount of the mortgage (generally 70% of the amount is
paid within six months of the claim and the remainder within the next six
months). The risks associated with this type of security are the same as other
mortgage securities -- prepayment and/or redemption prior to maturity, loss of
premium (if paid) if the security is redeemed prior to maturity and fluctuation
in principal value due to an increase or decrease in interest rates.

The average life of pass-through pools varies with the maturities of the
underlying mortgage instruments. In addition, the pool's term may be shortened
by unscheduled or early payments of principal and interest on the underlying
mortgages. The occurrence of mortgage prepayment is affected by factors
including the level of interest rates, general economic conditions, the location
and age of the mortgage and other social and demographic conditions.

As prepayment rates of individual pools vary widely, it is not possible to
accurately predict the average life of a particular pool. Mortgage pass-through
securities which receive regular principal payments have an average life less
than their maturity. The average life of mortgage pass-through investments will
typically vary from 1 to 18 years.


                                       17
<PAGE>


Yields on pass-through mortgage-backed securities are typically quoted based on
the maturity of the underlying instruments and the associated average life
assumption. Actual prepayment experience may cause the yield to differ from the
assumed average life yield. The compounding effect from reinvestments of monthly
payments received by the Fund will increase the yield to shareholders.

U.S. TREASURY INFLATION-PROTECTION SECURITIES. The Balanced Fund may invest in
inflation-protection securities, which are a new type of marketable book-entry
security issued by the United States Department of Treasury ("Treasury") with a
nominal return linked to the inflation rate in prices. Inflation-protection
securities will be auctioned and issued on a quarterly basis on the 15th of
January, April, July, and October, beginning on January 15, 1997. Initially,
they will be issued as 10-year notes, with other maturities added thereafter.
The index used to measure inflation will be the non-seasonably adjusted U.S.
City Average All Items Consumer Price Index for All Urban Consumers ("CPI-U").

The value of the principal will be adjusted for inflation, and every six months
the security will pay interest, which will be an amount equal to a fixed
percentage of the inflation-adjusted value of the principal. The final payment
of principal of the security will not be less than the original par amount of
the security at issuance.

The principal of the inflation-protection security will be indexed to the
non-seasonally adjusted CPI-U. To calculate the inflation-adjusted principal
value for a particular valuation date, the value of the principal at issuance is
multiplied by the index ratio applicable to that valuation date. The index ratio
for any date is the ratio of the reference CPI applicable to such date to the
reference CPI applicable to the original issue date. Semiannual coupon interest
is determined by multiplying the inflation-adjusted principal amount by one-half
of the stated rate of interest on each interest payment date.

Inflation-adjusted principal or the original par amount, whichever is larger,
will be paid on the maturity date as specified in the applicable offering
announcement. If at maturity the inflation-adjusted principal is less than the
original principal value of the security, an additional amount will be paid at
maturity so that the additional amount plus the inflation-adjusted principal
equals the original principal amount. Some inflation-protection securities may
be stripped into principal and interest components. In the case of a stripped
security, the holder of the stripped principal would receive this additional
amount. The final interest payment, however, will be based on the final
inflation-adjusted principal value, not the original par amount.

The reference CPI for the first day of any calendar month is the CPI-U for the
third preceding calendar month. (For example, the reference CPI for December 1
is the CPI-U reported for September of the same year, which is released in
October). The reference CPI for any other day of the month is calculated by a
linear interpolation between the reference CPI applicable to the first day of
the month and the reference CPI applicable to the first day of the following
month.

Any revisions the Bureau of Labor Statistics (or successor agency) makes to any
CPI-U number that had been previously released will not be used in calculations
of the value of outstanding inflation-protection securities. In the case that
the CPI-U for a particular month is not reported by the last day of the
following month, the Treasury will announce an index number based on the last
year-over-year CPI-U inflation rate available. Any calculations of the
Treasury's payment obligations on the inflation-protection security that need
that month's CPI-U number will be based on the index number that the Treasury
had announced. If the CPI-U is rebased to a different year, the Treasury will
continue to use the CPI-U series based on the base reference period in effect
when the security was first issued as long as that series continues to be
published. If the CPI-U is discontinued during the period the
inflation-protection security is outstanding, the Treasury will, in consultation
with the Bureau of Labor Statistics (or successor agency), determine an
appropriate substitute index and methodology for linking the discontinued series
with the new price index series. Determinations of the Secretary of the Treasury
in the regard are final.

Inflation-protection securities will be held and transferred in either of two
book-entry systems: the commercial book-entry system (TRADES) and TREASURY
DIRECT. The securities will be maintained and transferred at their original par
amount, i.e., not at their inflation-adjusted value. STRIPS components will be
maintained and transferred in TRADES at their value based on the original par
amount of the fully constituted security.

OTHER ASSET-BACKED SECURITIES. The Balanced Fund may invest in asset-backed
securities that are backed by consumer credit such as automobile receivables,
consumer credit card receivables, and home equity loans.


                                       18
<PAGE>


MUNICIPAL SECURITIES. Municipal securities in which the Balanced Fund may invest
include securities that are issued by states, territories and possessions of the
United States and the District of Columbia and their agencies, instrumentalities
and political subdivisions. Tax-exempt municipal securities include municipal
bonds, municipal notes and municipal commercial paper. MUNICIPAL BONDS generally
have maturities at the time of issuance ranging from one to thirty years, or
more. MUNICIPAL NOTES are short-term and generally mature in three months to
three years. MUNICIPAL COMMERCIAL PAPER matures in one year or less.

The yields on municipal securities are dependent on a variety of factors,
including the general level of interest rates, the financial condition of the
issuer, general conditions of the tax-exempt securities market, the size of the
issue, the maturity of the obligation and the rating of the issue. Ratings are
general, and not absolute, standards of quality. Consequently, securities of the
same maturity, interest rate and rating may have different yields, while
securities of the same maturity and interest rate with different ratings may
have the same yield.

COLLATERIALIZED MORTGAGE OBLIGATIONS (CMOs). The Balanced Fund may invest in
CMOs. CMOs are hybrid instruments with characteristics of both mortgage-backed
bonds and mortgage pass-through securities. Similar to a bond, interest and
principal on a CMO are paid, in most cases, monthly. CMOs may be collateralized
by whole mortgage loans, but are more typically collateralized by portfolios of
mortgage pass-through securities guaranteed by GNMA, FHLMC, or FNMA. Since CMOs
derive their return from underlying mortgages, they are commonly referred to as
derivative securities, but are not subject to the 100% limitation as discussed
in the "Futures and Options" section below. CMOs are structured into multiple
classes, with each class bearing a different stated maturity. Monthly payments
of principal, including prepayments, are first returned to investors holding the
shortest maturity class; investors holding the longer maturity classes receive
principal only after the earlier classes have been retired. CMOs that are issued
or guaranteed by the U.S. Government or by any of its agencies or
instrumentalities will be considered U.S. Government securities by the Balanced
Fund, while other CMOs, even if collateralized by U.S. Government securities,
will have the same status as other privately issued securities for purposes of
applying the Fund's diversification tests. For a discussion of prepayment risks,
see "Mortgage and Other Asset-Backed Securities" section above.

VARIABLE RATE NOTES. The Balanced Fund may purchase floating and variable rate
notes. The interest rate is adjusted either at predesignated periodic intervals
(variable rate) or when there is a change in the index rate on which the
interest rate on the obligation is based (floating rate). These notes normally
have a demand feature which permit the holder to demand payment of principal
plus accrued interest upon a specified number of days' notice. The issuer of
floating and variable rate demand notes normally has a corresponding right,
after a given period, to prepay at its discretion the outstanding principal
amount of the note plus accrued interest upon a specified number of days' notice
to the noteholders.

ZERO COUPON SECURITIES. The Balanced Fund is permitted to invest in zero coupon
securities. Such securities are debt obligations which do not entitle the holder
to periodic interest payments prior to maturity and are issued and traded at a
discount from their face amounts. The discount varies depending on the time
remaining until maturity, prevailing interest rates, liquidity of the security
and the perceived credit quality of the issuer. The discount, in the absence of
financial difficulties of the issuer, decreases as the final maturity of the
security approaches. Zero coupon securities can be sold prior to their due date
in the secondary market at the then-prevailing market value which depends
primarily on the time remaining to maturity, prevailing levels of interest rates
and the perceived credit quality of the issuer. The market prices of zero coupon
securities are more volatile than the market prices of securities of comparable
quality and similar maturity that pay interest periodically and may respond to a
greater degree to fluctuations in interest rates than do such non-zero coupon
securities.

TRUST PREFERRED SECURITIES. The Balanced Fund may purchase trust preferred
securities issued primarily by financial institutions such as banks and
insurance companies. Trust preferred securities purchased by the Fund generally
have a stated par value, a stated maturity typically of 30 years, are callable
after a set time period of typically five or ten years and pay interest
quarterly or semi-annually. The proceeds from the issuance of the securities are
placed in a single asset trust controlled by the issuer holding company, and the
trust in-turn purchases long-term junior subordinated debt of the issuer holding
company. The junior subordinated debt held by the trust is senior to all common
and preferred stock of the issuer. The junior subordinated debt instruments
include deferral provisions whereby the issuer holding company may defer
interest payments for up to five years under certain circumstances, provided
that no dividend payments are made with respect to outstanding common and
preferred stock, and during a period of interest deferral the securities earn


                                       19
<PAGE>


compounded interest which is accrued by the issuer as an interest expense. The
Federal Reserve Bank limits the amount of trust preferred securities that an
issuer may have outstanding such that the total of cumulative preferred stock
and trust preferred securities outstanding may not exceed 25 percent of the
issuer's Tier 1 capital base. The securities provide that they are immediately
callable in the event of a change in the tax law whereby the interest paid by
the issuer is no longer treated as an interest expense deduction by the issuer.

ILLIQUID SECURITIES
- --------------------------------------------------------------------------------
Each Fund may invest up to 15% of its net assets in all forms of "illiquid
securities." An investment is generally deemed to be "illiquid" if it cannot be
disposed of within seven days in the ordinary course of business at
approximately the amount at which such securities are valued by the Fund.
Restricted securities are securities which were originally sold in private
placements and which have not been registered under the Securities Act of 1933
(the "1933 Act"). Such securities generally have been considered illiquid by the
staff of the Securities and Exchange Commission (the "SEC"), since such
securities may be resold only subject to statutory restrictions and delays or if
registered under the 1933 Act. However, the SEC has recently acknowledged that a
market exists for certain restricted securities (for example, securities
qualifying for resale to certain "qualified institutional buyers" pursuant to
Rule 144A under the 1933 Act). Additionally, a similar market exists for
commercial paper issued pursuant to the private placement exemption of Section
4(2) of the 1933 Act. As a fundamental policy, the Funds may invest without
limitation in these forms of restricted securities if such securities are
determined by the Adviser to be liquid in accordance with standards established
by the Funds' Board of Directors.

Under these standards, the Adviser must consider (a) the frequency of trades and
quotes for the security, (b) the number of dealers willing to purchase or sell
the security and the number of other potential purchasers, (c) dealer
undertakings to make a market in the security, and (d) the nature of the
security and the nature of the marketplace trades (for example, the time needed
to dispose of the security, the method of soliciting offers and the mechanics of
transfer).

At the present time, it is not possible to predict with accuracy how the markets
for certain restricted securities will develop. Investing in restricted
securities could have the effect of increasing the level of a Fund's illiquidity
to the extent that qualified institutional buyers become, for a time,
uninterested in purchasing these securities.

RATINGS OF DEBT SECURITIES
- --------------------------------------------------------------------------------
Investment grade debt securities are rated AAA, AA, A or BBB by Standard &
Poor's Corporation ("S& P"), Fitch IBCA ("Fitch"), and Duff & Phelps Credit
Rating Co. ("Duff & Phelps"); or Aaa, Aa, A or Baa by Moodys Investors Services
("Moody's"). Investment grade municipal notes are rated MIG 1, MIG 2, MIG 3 or
MIG 4 (VMIG 1, VMIG 2, VMIG 3 or VMIG 4 for notes with a demand feature) by
Moodys or SP-1 or SP-2 by S&P. Securities rated Baa, MIG 4, VMIG 4 or BBB are
medium grade, involve some speculative elements and are the lowest investment
grade available. These securities generally have less certain protection of
principal and interest payments than higher rated securities. Securities rated
Ba or BB (in which Large Cap Fund, Balanced Fund and Developing Markets Growth
Fund may invest) are judged to have some speculative elements with regard to
capacity to pay interest and repay principal. Debt securities rated C (in which
the Developing Markets Growth Fund may invest) are regarded as having
predominantly speculative characteristics. DEBT SECURITIES RATED BELOW
INVESTMENT GRADE ARE COMMONLY KNOWN AS JUNK BONDS. Presently, other than with
respect to the Balanced Fund, the Adviser intends to invest only in debt
securities rated at investment grade at the time of purchase, or if not rated,
deemed by the Adviser to be of comparable quality. See the section "Investment
Objectives and Policies" above for a discussion regarding the Balanced Fund's
debt securities ratings. See the Statement of Additional Information for further
information about ratings.

The commercial paper purchased by the Funds will consist only of direct
obligations which, at the time of purchase, are (a) rated P-1 by Moody's or A-1
by S& P, or (b) if not rated, issued by companies having an outstanding
unsecured debt issue which at the time of purchase is rated Aa or higher by
Moody's or AA or higher by S&P.

SIT MONEY MARKET FUND
- --------------------------------------------------------------------------------
The Funds may invest up to 25% of their total net assets in shares of money
market funds advised by the Adviser, which includes the Money Market Fund,
subject to the conditions contained in an exemptive order (the "Exemptive
Order") issued to the Funds and the Adviser by the Securities and Exchange
Commission.


                                       20
<PAGE>


Such investments may be made in lieu of direct investments in short term money
market instruments if the Adviser believes that they are in the best interest of
the Funds. The Exemptive Order requires the Adviser and its affiliates, in their
capacities as service providers for the Money Market Fund, to remit to the
Funds, or waive, an amount equal to all fees otherwise due to them under their
advisory and other agreements with the Money Market Fund to the extent such fees
are based upon a Fund's assets invested in shares of the Money Market Fund. This
requirement is intended to prevent shareholders of the Funds from being
subjected to double management and other asset-based fees as a result of a
Fund's investments in the Money Market Fund.

DIVERSIFICATION
- --------------------------------------------------------------------------------
As a fundamental policy (in addition to the fundamental policies and
restrictions set forth in the Prospectus and this Statement of Additional
Information), each Fund intends to operate as a "diversified" management
investment company, as defined in the Investment Company Act of 1940, as
amended. A "diversified" investment company means a company which meets the
following requirements: At least 75% of the value of the company's total assets
is represented by cash and cash items (including receivables), "Government
Securities", securities of other investment companies, and other securities for
the purposes of this calculation limited in respect of any one issuer to an
amount not greater in value than 5% of the value of the total assets of such
management company and to not more than 10% of the outstanding voting securities
of such issuer. "Government Securities" means securities issued or guaranteed as
to principal or interest by the United States, or by a person controlled or
supervised by and acting as an instrumentality of the Government of the United
States pursuant to authority granted by the Congress of the United States; or
certificates of deposit for any of the foregoing. Additionally, as set forth
above, each of the Funds has adopted certain restrictions that are more
restrictive than the policies set forth in this paragraph.

SECURITIES LENDING
- --------------------------------------------------------------------------------
The lending of portfolio securities to broker-dealers, banks, and other
institutions may increase the average annual return to shareholders. Lending of
portfolio securities also involves certain risks to a Fund. As with other
extensions of credit, there are risks of delay in recovery of loaned securities,
or even loss of rights in collateral pledged by the borrower, should the
borrower fail financially. However, the Funds will only enter into loan
agreements with broker-dealers, banks, and other institutions which the Adviser
has determined are creditworthy. The Funds may also experience a loss if, upon
the failure of a borrower to return loaned securities, the collateral is not
sufficient in value or liquidity to cover the value of such loaned securities
(including accrued interest thereon). However, the borrower will be required to
pledge collateral which the custodian for a Fund's portfolio securities will
take into possession before any securities are loaned. Additionally, the
borrower may pledge only cash, securities issued or guaranteed by the U.S.
Government or its agencies and instrumentalities, certificate of deposit or
other high-grade, short-term obligations or interest-bearing cash equivalents as
collateral. There will be a daily procedure to ensure that the pledged
collateral is equal in value to at least 100% of the value of the securities
loaned. Under such procedure, the value of the collateral pledged by the
borrower as of any particular business day will be determined on the next
succeeding business day. If such value is less than 100% of the value of the
securities loaned, the borrower will be required to pledge additional
collateral. The risks of borrower default (and the resultant risk of loss to a
Fund) also are reduced by lending only securities for which a ready market
exists. This will reduce the risk that the borrower will not be able to return
such securities due to its inability to cover its obligation by purchasing such
securities on the open market.

To the extent that collateral is comprised of cash, a Fund will be able to
invest such collateral only in securities issued or guaranteed by the U.S.
Government or its agencies and instrumentalities and in certificates of deposit
or other high-grade, short-term obligations or interest-bearing cash
equivalents. If a Fund invests cash collateral in such securities, the Fund
could experience a loss if the value of such securities declines below the value
of the cash collateral pledged to secure the loaned securities. The amount of
such loss would be the difference between the value of the collateral pledged by
the borrower and the value of the securities in which the pledged collateral was
invested.

Although there can be no assurance that the risks described above will not
adversely affect a Fund, the Adviser believes that the potential benefits that
may accrue to a Fund as a consequence of securities lending will outweigh any
such increase in risk.

ADDITIONAL INFORMATION ABOUT SELLING SHARES
- --------------------------------------------------------------------------------

SUSPENSION OF SELLING ABILITY
- --------------------------------------------------------------------------------
Each Fund may suspend selling privileges or postpone the date of payment:
- -    During any period that the NYSE is closed other than customary weekend or
     holiday closings, or when trading is restricted, as determined by the
     Securities and Exchange Commission ("SEC");
- -    During any period when an emergency exists, as determined by the SEC, as a
     result of which it is not reasonably practical for the Fund to dispose of
     securities owned by it or to fairly determine the value of its assets;
- -    For such other periods as the SEC may permit.

TELEPHONE TRANSACTIONS
- --------------------------------------------------------------------------------
Once you place a telephone transaction request to Sit Mutual Funds, it cannot be
canceled or modified. The Funds use reasonable procedures to confirm that
telephone instructions are genuine, including requiring that payments be made
only to the shareholder's address of record or the bank account designated on
the application and requiring certain means of telephone identification. If the
Fund fails to employ such procedures, it may be liable for any losses suffered
by Fund shareholders as a result of unauthorized or fraudulent instructions.
During times of chaotic economic or market circumstances, a shareholder may have
difficulty reaching the Funds by telephone. Consequently, a redemption or
exchange by telephone may be difficult to implement at those times.

REDEMPTION-IN-KIND
- --------------------------------------------------------------------------------
If the Adviser determines that existing conditions make cash payments
undesirable, redemption payments may be made in whole or in part in securities
or other financial assets, valued for this purpose as they are valued in
computing the NAV for a Fund's shares. Shareholders receiving securities or
other financial assets on redemption may realize a gain or loss for tax purposes
and will incur any costs of sale, as well as the associated inconveniences.

COMPUTATION OF NET ASSET VALUE
- --------------------------------------------------------------------------------

Net asset value is determined as of the close of the New York Stock Exchange on
each day that the exchange is open for business and on any other day on which
there is sufficient trading in a Fund's securities to materially affect the
Fund's net asset value per share. The customary national business holidays
observed by the New York Stock Exchange and on which the Funds are closed are:
New Year's Day, Martin Luther King Jr. Day, President's Day, Good Friday,
Memorial Day, July Fourth, Labor Day, Thanksgiving Day and Christmas Day. The
net asset value per share will not be determined on these national holidays.

On June 30, 1999, the net asset value and public offering price per share for
each Fund was calculated as follows:

Balanced Fund:
     net assets         $12,112,363
     ------------------------------
     shares outstanding     697,061  = net asset value (NAV) per share =

CALCULATION OF PERFORMANCE DATA
- --------------------------------------------------------------------------------
Advertisements and other sales literature for the Funds may refer to cumulative
total return, average annual total return and yield.

CUMULATIVE TOTAL RETURN. Total return means cumulative total return and is
calculated by finding the cumulative compounded rate of return over the period
indicated that would equate the initial amount invested to the ending redeemable
value, according to the following formula:

               EVR - P
      CTR  = ( ------- ) x 100
                  P

      CTR  =  cumulative total return
      ERV  =  ending redeemable value at the end of the period of a hypothetical
              $1,000 payment made at the beginning of such period
      P    =  initial payment of $1,000

This calculation assumes all dividends and capital gains distributions are
reinvested at net asset value on the appropriate reinvestment dates and includes
all recurring fees, such as investment advisory and management fees, charged to
all shareholder accounts.

AVERAGE ANNUAL TOTAL RETURN. Average annual total return is computed by finding
the average annual compounded rates of return over the periods indicated that
would equate the initial amount invested to the ending redeemable value,
according to the following formula:

       P(1+T)nth power = ERV
             P  =  a hypothetical initial payment of $1,000;
             T  =  average annual total return;
             n  =  number of years; and
           ERV  =  ending redeemable value at the end of the period of a
                   hypothetical $1,000 payment made at the beginning of such
                   period.

This calculation assumes all dividends and capital gains distributions are
reinvested at net asset value on the appropriate reinvestment dates and includes
all recurring fees, such as investment advisory and management fees, charged to
all shareholder accounts.

YIELD. Yield is computed by dividing the net investment income per share (as
defined under Securities and Exchange Commission rules and regulations) earned
during the computation period by the maximum offering price per share on the
last day of the period, according to the following formula:


                                       23
<PAGE>


                    a - b
       Yield  = 2 ( ----- + 1 ) 6th power - 1
                     cd

         a    =  dividends and interest earned during the periods;
         b    =  expenses accrued for the period (net of reimbursements);
         c    =  the average daily number of shares outstanding during the
                 period that were entitled to receive dividends; and
         d    =  the maximum offering price per share on the last day of the
                 period.

MANAGEMENT
- --------------------------------------------------------------------------------

The Large Cap Growth Fund, Mid Cap Growth Fund, and the corporate issuer of the
Balanced Fund, Regional Growth Fund, International Growth Fund, Small Cap Growth
Fund, Science and Technology Growth Fund and Developing Markets Growth Fund,
have corporate officers and Boards of Directors. Pursuant to Minnesota law, the
Boards of Directors are responsible for the management of the Funds and the
establishment of the Funds' policies. The officers of the Funds manage the
day-to-day operation of the Funds.

The Sit Funds as a group (a total of 13 Funds) pay each director, who is not
also an officer, an annual total fee of $12,000, $2,000 for each meeting
attended, and provide reimbursement for travel and other expenses. The following
table sets forth the aggregate compensation received by each Director for
services provided to the thirteen funds of the Sit Mutual Funds. Pursuant to
each Fund's investment management agreement with the Adviser, the Adviser is
obligated to pay the Funds' expenses, including fees paid to the directors. (See
discussion under "Investment Adviser" below.) Directors who are officers of the
Adviser or any of its affiliates did not receive any such compensation and are
not included in the table.

*    Directors who are deemed to be "interested persons" of the Funds as that
     term is defined by the Investment Company Act of 1940. Messrs. Sit and
     Mitchelson are interested persons because they are officers of the Adviser.
     Mr. Frenzel is an interested person of the International Growth Fund and
     Developing Markets Growth Fund because he is a director of the Sub-Adviser,
     and may be deemed to be an interested person of all Funds because he is an
     advisory director and shareholder of the Adviser.

Mr. Roger Sit, Mr. Ron Sit, and Mr. Robert Sit are sons of Eugene C. Sit.

INVESTMENT ADVISER
- --------------------------------------------------------------------------------

The Adviser (or an affiliate) has served as the investment adviser for each Fund
since the inception of each Fund.

TERMS COMMON TO ALL FUNDS' INVESTMENT MANAGEMENT AGREEMENTS
- --------------------------------------------------------------------------------
Each Fund's Investment Management Agreement provides that the Adviser will
manage the investment of the Fund's assets, subject to the applicable provisions
of the Fund's articles of incorporation, bylaws and current registration
statement (including, but not limited to, the investment objective, policies and
restrictions delineated in the Fund's current prospectus and Statement of
Additional Information), as interpreted from time to time by the Fund's Board of
Directors. Under each Agreement, the Adviser has the sole and exclusive
responsibility for the management of the Fund's investment portfolio and for
making and executing all investment decisions for the Fund. The Adviser is
obligated under each Agreement to report to the Fund's Board of Directors
regularly at such times and in such detail as the Board may from time to time
determine appropriate, in order to permit the Board to determine the adherence
of the Adviser to the Fund's investment policies. Each Agreement also provides
that the Adviser shall not be liable for any loss suffered by the Fund in
connection with the matters to which the Agreement relates, except losses
resulting from willful misfeasance, bad faith or gross negligence on the part of
the Adviser in the performance of its obligations and duties or by reason of its
reckless disregard of its obligations and duties under the Agreement.

Each Agreement provides that the Adviser shall, at its own expense, furnish all
office facilities, equipment and personnel necessary to discharge its
responsibilities and duties under the Agreement and that the Adviser will
arrange, if requested by the Fund, for officers or employees of the Adviser to
serve without compensation from the Fund as directors, officers or employees of
the Fund if duly elected to such positions by the shareholders or directors of
the Fund.

Each Agreement provides that the Adviser will bear all of the Fund's expenses,
except for extraordinary expenses (as designated by a majority of the Fund's
disinterested directors), interest, brokerage commissions and other transaction
charges relating to the investing activities of the Fund.

Each Investment Management Agreement provides that it will continue in effect
from year to year only as long as such continuance is specifically approved at
least annually by the applicable Fund's Board of Directors or shareholders and
by a majority of the Board of Directors who are not "interested persons" (as
defined in the 1940 Act) of the Adviser or the Fund. The Agreement is terminable
upon 60 days' written notice by the Adviser or the Fund and will terminate
automatically in the event of its "assignment" (as defined in the 1940 Act).


COMPENSATION AND ALLOCATION OF EXPENSES
- --------------------------------------------------------------------------------
Under each of the Fund's Investment Management Agreement, the Fund is obligated
to pay the Adviser a flat monthly fee, which is equal on an annual basis to the
following percentages of the average daily net assets of the Funds:

Sit Balanced Fund                                1.00%
Sit Large Cap Growth Fund, Inc.                  1.00%

     2000, the Adviser has voluntarily agreed to limit management fee (and
     thereby, all Fund expenses, except those not payable by the Adviser as set
     forth above) to 1.00% of the Regional Growth Fund's average daily net
     assets and 1.25% of the Science and Technology Growth Fund's average daily
     net assets. After December 31, 2000, these voluntary fee waivers may be
     discontinued by the Adviser in its sole discretion.

(2)  For the period November 1, 1996 through December 31, 2000, the Adviser has
     voluntarily agreed to limit the management fee (and thereby, all Fund
     expenses, except those not payable by the Adviser as set forth above) of
     the Mid Cap Growth Fund to 1.00% of the Fund's average daily net assets.
     After December 31, 2000, this voluntary fee waiver may be discontinued by
     the Adviser in its sole discretion.

(3)  For the period January 1, 1994 through December 31, 2000, the Adviser has
     voluntary agreed to limit the management fee (and thereby, all Fund
     expenses, except those not payable by the Adviser as set forth above) of
     the International Growth Fund to 1.50% per year of the Fund's average daily
     net assets. After December 31, 2000, this voluntary fee waiver may be
     discontinued by the Adviser at its sole discretion.

Prior to November 1, 1996 the Investment Management Agreement between the
Adviser and each of Large Cap Growth Fund and Mid Cap Growth Fund provided that
the Fund was obligated to pay the Adviser a monthly fee based on average daily
net assets ("net assets") on an annual basis equal to 1.00% for the first $30
million of net assets, .75% for the next $70 million of net assets and .50% for
the excess of $100 million of net assets. The Adviser was obligated to reimburse
each of Large Cap Growth Fund and Mid Cap Growth Fund for all of the Fund's
expenses except for extraordinary expenses (as designated by a majority of each
Fund's disinterested directors), interest, brokerage commissions and other
transaction charges relating to each Fund's investing activities (which expenses
were the sole responsibility of the Fund, irrespective of amount), which exceed,
on an annual basis, an amount equal to 1.50% of the first $30 million of the
Fund's average daily net assets and 1.00% of average daily net assets in excess
of $30 million. Subject to this expense limitation, each of Large Cap Growth
Fund and Mid Cap Growth Fund was responsible for all of its expenses to the
extent not specifically assumed by the Adviser under the Agreement. For the
period October 1, 1993 through October 31, 1996, the Adviser voluntarily agreed
to absorb expenses that were otherwise payable by the Large Cap Growth Fund
which exceeded 1.00% of the Fund's average daily net assets.

Set forth below are the investment management fees and other expenses paid by
each of the Large Cap Growth Fund, Mid Cap Growth Fund, Small Cap Growth Fund,
Balanced Fund, International Growth Fund, and Developing Markets Growth Fund
during the fiscal years ended June 30, 1999, 1998, and 1997; the Regional Growth
Fund and Science and Technology Growth Fund during the fiscal year ended June
30, 1998. Fees and expenses of the Funds waived or paid by the Adviser during
such fiscal years are also set forth below.

THE SUB-ADVISER - INTERNATIONAL GROWTH FUND AND DEVELOPING MARKETS GROWTH FUND
- --------------------------------------------------------------------------------
The International Growth Fund's and Developing Markets Growth Fund's Investment
Management Agreements authorize the Adviser, at its option and at its sole
expense, to appoint a sub-adviser, which may assume all or such responsibilities
and obligations of the Adviser pursuant to the Investment Management Agreement
as shall be delegated to the sub-adviser; provided, however, that any
discretionary investment decisions made by the sub-adviser shall be subject to
approval or ratification by the Adviser, and any appointment of a sub-adviser
and assumption of responsibilities and obligations of the Adviser by such
sub-adviser shall be subject to approval by the Board of Directors, and as
required by law the shareholders,


                                       28
<PAGE>


of the Company; and provided, further, that the appointment of any sub-adviser
shall in no way limit or diminish the Adviser's obligations and responsibilities
under the Investment Management Agreement. Pursuant to this authority, the
Sub-Adviser serves as International Growth Fund's and Developing Markets Growth
Fund's Sub-Adviser.

The current Sub-Advisory Agreement provides that the Sub-Adviser agrees to
manage the investment of International Growth Fund's and Developing Markets
Growth Fund's assets, subject to the applicable provisions of the Funds'
articles of incorporation, bylaws and current registration statement (including,
but not limited to, the investment objective, policies and restrictions
delineated in the Fund's current prospectus and Statement of Additional
Information), as interpreted from time to time by the Fund's Board of Directors.
The Agreement also provides that any discretionary investment decisions made by
the Sub-Adviser are subject to the Adviser's review, approval or ratification at
the Adviser's discretion.

For its services under the Sub-Advisory Agreement, absent any voluntary fee
waivers, the Adviser has agreed to pay the Sub-Adviser a monthly fee equal to
the percentages set forth below of the value of the International Growth Fund's
and Developing Markets Growth Fund's average daily net assets:

Pursuant to the Investment Management Agreement the Adviser paid the Sub-Adviser
fees of $569,650, $627,994 and $602,981 for the fiscal years ended June 30,
1997, 1998 and 1999 respectively with respect to services provided on behalf of
the International Growth Fund; and fees of $86,493, $104,245 and $78,208 for the
fiscal years ended June 30, 1997, 1998 and 1999 with respect to services
provided on behalf of the Developing Markets Growth Fund.

The Sub-Advisory Agreement continues in effect from year to year only as long as
such continuance is specifically approved at least annually by (i) the Board of
Directors of the Fund or by the vote of a majority of the outstanding voting
shares of the Fund, and (ii) by the vote of a majority of the directors of the
Company who are not parties to the Agreement or interested persons of the
Adviser, the Sub-Adviser, the International Growth Fund or the Developing
Markets Growth Fund. The Agreement may be terminated at any time, without the
payment of any penalty, by the Board of Directors of Sit Mutual Funds, Inc., the
issuer of the International Growth Fund and Developing Markets Growth Fund or by
the vote of a majority of the outstanding voting shares of the Fund, or by the
Sub-Adviser or the Adviser, upon 30 days' written notice to the other party.
Additionally, the Agreement automatically terminates in the event of its
assignment.

DISTRIBUTOR
- --------------------------------------------------------------------------------

Each of the Funds have entered into Underwriting and Distribution Agreements
with SIA Securities Corp. ("Securities"), an affiliate of the Adviser, pursuant
to which Securities will act as each Fund's principal underwriter. Securities
will market each Fund's shares only to certain institutional investors and all
other sales of each Fund's shares will be made by each Fund. The Adviser will
pay all expenses of Securities in connection with such services and Securities
is otherwise not entitled to any other compensation under the Underwriting and
Distribution Agreement. Each Fund will incur no additional fees in connection
with the Underwriting and Distribution Agreement.

Pursuant to the Underwriting and Distribution Agreement, Securities has agreed
to act as the principal underwriter for each Fund in the sale and distribution
to the public of shares of each Fund, either through dealers or otherwise.
Securities has agreed to offer such shares for sale at all times when such
shares are available for sale and may lawfully be offered for sale and sold. The
Underwriting and Distribution Agreement is renewable from year to year if the
Fund's directors approve such agreement. The Fund or Securities can terminate
the Underwriting and Distribution Agreement at any time without penalty on 60
days' notice written notice to the other party. The Underwriting and
Distribution Agreement terminates automatically upon its assignment. In the
Underwriting and Distribution Agreement, Securities agrees to indemnify each
Fund against all costs of litigation and other legal proceedings and against any
liability incurred by or imposed on the Fund in any way arising out of or in
connection with the sale or distribution of each Fund's shares, except to the
extent that such liability is the result of information which was obtainable by
Securities only from persons affiliated with the Fund but not Securities.


                                       29
<PAGE>


Securities or the Adviser may enter into agreements with various brokerage or
other firms pursuant to which such firms provide certain administrative services
with respect to customers who are beneficial owners of shares of the Funds. The
Adviser or Securities may compensate such firms for the services provided, which
compensation is based on the aggregate assets of customers that are invested in
the Funds.

BROKERAGE
- --------------------------------------------------------------------------------

Transactions on a stock exchange in equity securities will be executed primarily
through brokers that will receive a commission paid by the applicable Fund.
Fixed income securities, as well as equity securities traded in the
over-the-counter market, are generally traded on a "net" basis with dealers
acting as principals for their own accounts without a stated commission,
although the price of the security usually includes a profit to the dealer. In
underwritten fixed income and equity offerings, securities are purchased at a
fixed price that includes an amount of compensation to the underwriter,
generally referred to as the underwriter's selling concession or discount.
Certain of these securities may also be purchased directly from the issuer, in
which case neither commissions nor discounts are paid.

The Adviser (or Sub-Adviser, as applicable) selects and, where applicable,
negotiates commissions with the broker-dealers who execute the transactions for
one or more of the Funds. The primary criterion for the selection of a
broker-dealer is the ability of the broker-dealer, in the opinion of the Adviser
(or Sub-Adviser, as applicable) to secure prompt execution of the transactions
on favorable terms, including the best price of the security, the reasonableness
of the commission and considering the state of the market at the time. When
consistent with these objectives, business may be placed with broker-dealers who
furnish investment research or services to the Adviser or Sub-Adviser. Such
research or services include advice, both directly and in writing, as to the
value of securities, the advisability of investing in, purchasing or selling
securities, and the availability of securities, or purchasers or sellers of
securities. Such services also may include analyses and reports concerning
investment issues, industries, securities, economic factors and trends,
portfolio strategy, the performance of accounts, and trading systems. Some
services may require the use of hardware provided by the information provider.
This allows the Adviser (or Sub-Adviser, as applicable) to supplement its own
investment research activities and enables the Adviser (or Sub-Adviser, as
applicable) to obtain the views and information of individuals and research
staffs of many different securities firms prior to making investment decisions
for the Funds. To the extent portfolio transactions are effected with
broker-dealers who furnish research services to the Adviser or Sub-Adviser, the
Adviser or Sub-Adviser receives a benefit, not capable of valuation in dollar
amounts, without providing any direct monetary benefit to the applicable Funds
from these transactions. The Adviser and the Sub-Adviser believe that most
research services they receive generally benefit several or all of the
investment companies and private accounts which they manage, as opposed to
solely benefiting one specific managed fund or account. Normally, research
services obtained through managed funds or accounts investing in common stocks
would primarily benefit the managed funds or accounts which invest in common
stock; similarly, services obtained from transactions in fixed income securities
would normally be of greater benefit to the managed funds or accounts which
invest in debt securities.

Both the Adviser and the Sub-Adviser maintain an informal list of
broker-dealers, which is used from time to time as a general guide in the
placement of Fund business, in order to encourage certain broker-dealers to
provide the Adviser and the Sub-Adviser with research services which the Adviser
and the Sub-Adviser anticipate will be useful to them in managing the Funds.
Because the list is merely a general guide, which is to be used only after the
primary criterion for the selection of broker-dealers (discussed above) has been
met, substantial deviations from the list are permissible and may be expected to
occur. Each of the Adviser and the Sub-Adviser will authorize a Fund to pay an
amount of commission for effecting a securities transaction in excess of the
amount of commission another broker-dealer would have charged only if the
Adviser (or Sub-Adviser, as applicable) determines in good faith that such
amount of commission is reasonable in relation to the value of the brokerage and
research services provided by such broker-dealer, viewed in terms of either that
particular transaction or the Adviser's or Sub-Adviser's overall
responsibilities with respect to the accounts as to which it exercises
investment discretion. Generally, the Fund pays commissions higher than the
lowest commission rates available. Some investment companies enter into
arrangements under which a broker-dealer agrees to pay the cost of certain
products or services (not including research services) in exchange for fund
brokerage ("brokerage/services arrangements"). Under a typical brokerage/service
arrangement, a broker agrees to pay a fund's custodian fees or transfer agent
fees and, in exchange, the fund agrees to direct a minimum amount of brokerage
to the broker. The Adviser does not intend to enter into such brokerage/service
arrangements on behalf of the Funds. Some investment companies enter into
arrangements that provide for


                                       30
<PAGE>


specified or reasonably ascertainable fee reductions in exchange for the use of
fund assets ("expense offset arrangements"). Under such expense offset
agreements, expenses are reduced by foregoing income rather than by
re-characterizing them as capital items. For example, a fund may have a
"compensating balance" agreement with its custodian under which the custodian
reduces its fee if the fund maintains cash or deposits with the custodian in
non-interest bearing accounts. The Adviser does not intend to enter into expense
offset agreements involving assets of the Funds.

Most all domestic (U.S.) securities trades will be executed through U.S.
brokerage firms and commercial banks. Most foreign equity securities will be
obtained in over-the-counter markets or stock exchanges located in the countries
in which the respective principal offices of the issuers of the various
securities are located, if that is the best available market. The fixed
commissions paid in connection with most such foreign stock transactions
generally are higher than negotiated commissions on United States transactions.
There generally is less government supervision and regulation of foreign stock
exchanges and brokers than in the United States. Foreign security settlements
may in some instances be subject to delays and related administrative
uncertainties.

Foreign equity securities may be held in the form of American Depository
Receipts ("ADRs"), European Depository Receipts ("EDRs"), or securities
convertible into foreign equity securities. ADRs or EDRs may be listed on stock
exchanges, or traded in the over-the-counter markets in the United States or
Europe, as the case may be. ADRs, like other securities traded in the United
States, will be subject to negotiated commission rates. The foreign and domestic
debt securities and money market instruments in which International Growth Fund
may invest are generally traded in the over-the-counter markets.

Fund management does not currently anticipate that the Fund will effect
brokerage transactions in its portfolio securities with any broker-dealer
affiliated directly or indirectly with the Funds, the Adviser or the
Sub-Adviser.

The Adviser has entered into agreements with Capital Institutional Services,
Inc. ("CIS"), and Autranet, Inc. ("AI"), unaffiliated registered broker-dealers.
All transactions placed with CIS and LAS are subject to the above criteria. CIS
and AI provide the Adviser with a wide variety of economic, performance, and
investment research information, resources from Egan-Jones Rating Company, Fitch
Investors Service, Inc., Moody's Investors Service Inc., Municipal Market Data,
Standard & Poor's Corporation, Bloomburg, L.P., Institutional Investor, Pattern
Recognition Research Inc., and Stone & McCarthy Research Associates.

Investment decisions for each Fund are made independently of those for other
clients of the Adviser, including the other Funds. When the Funds or clients
simultaneously engage in the purchase or sale of the same securities, the price
of the transactions is averaged and the amount allocated in accordance with a
formula deemed equitable to each Fund and client. In some cases, this system may
adversely affect the price paid or received by the Fund or the size of the
position obtainable. Total brokerage commissions paid by the Funds for the three
most recent fiscal years include commissions as set forth below which were paid
to firms that supplied the Funds and Adviser with statistical and research
services.

</TABLE>

TAXES
- --------------------------------------------------------------------------------

The tax status of the Funds and the distributions which they may make are
summarized in the prospectus in the section entitled "Taxes." Each Fund intends
to fulfill the requirements of Subchapter M of the Internal Revenue Code of
1986, as amended (the "Code"), as a regulated investment company. If so
qualified, each Fund will not be liable for federal income taxes to the extent
it distributes its taxable income to its shareholders.

To qualify under Subchapter M for tax treatment as a regulated investment
company, each Fund must, among other things: (1) distribute to its shareholders
at least 90% of its investment company taxable income (as that term is defined
in the Code determined without regard to the deduction for dividends paid) and
90% of its net tax-exempt income; (2) derive at least 90% of its gross income
from dividends, interest, payments with respect to securities loans, gains from
the sale or other disposition of stock or securities, or other income derived
with respect to its business of investing in such stocks, securities, or
currency; and (3) diversify its holdings so that, at the end of each fiscal
quarter of the Fund, (a) at least 50% of the market value of the Fund's assets
is represented by cash, cash items, United States Government securities and
securities of other regulated investment companies, and other securities, with
these other securities limited, with respect to any one issuer, to an amount no
greater than 5% of the Fund's total assets and no greater than 10% of the
outstanding voting securities of such issuer, and (b) not more than 25% of the
market value of the Fund's total assets is invested in the securities of any one
issuer (other than United States Government securities or securities of other
regulated investment companies).

Each Fund is subject to a non-deductible excise tax equal to 4% of the excess,
if any, of the amount required to be distributed for each calendar year over the
amount actually distributed. In order to avoid the imposition of this excise
tax, each Fund must declare and pay dividends representing 98% of its net
investment income for that calendar year and 98% of its capital gains (both
long-term and short-term) for the twelve-month period ending October 31 of the
calendar year.

When shares of a Fund are sold or otherwise disposed of, the Fund shareholder
will realize a capital gain or loss equal to the difference between the purchase
price and the sale price of the shares disposed of, if, as is usually the case,
the Fund shares are a capital asset in the hands of the Fund shareholder. In
addition, pursuant to a special provision in the Code, if Fund shares with
respect to which a long-term capital gain distribution has been made are held
for six months or less, any loss on the sale or other disposition of such shares
will be a long-term capital loss to the extent of such long-term capital gain
distribution. Any loss on the sale or exchange of shares of a Fund generally
will be disallowed to the extent that a shareholder acquires or contracts to
acquire shares of the same Fund within 30 days before or after such sale or
exchange.

Some of the investment practices that may be employed by the Funds will be
subject to special provisions that, among other things, may defer the use of
certain losses of such Funds, affect the holding period of the securities held
by the Funds and, particularly in the case of transactions in or with respect to
foreign currencies, affect the character of the gains or losses realized. These
provisions may also require the Funds to mark-to market some of the positions in
their respective portfolios (i.e., treat them as closed out) or to accrue
original discount, both of which may cause such Funds to recognize income
without receiving cash with which to make distributions in amounts necessary to
satisfy the distribution requirements for qualification as a regulated
investment company and for avoiding income and excise taxes. Accordingly, in
order to make the required distributions, a Fund may be required to borrow or
liquidate securities. Each Fund will monitor its transactions and may make
certain elections in order to mitigate the effect of these rules and prevent
disqualification of the Funds as regulated investment companies.


                                       33
<PAGE>


It is expected that any net gain realized from the closing out of forward
currency contracts will be considered gain from the sale of securities or
currencies and therefore be qualifying income for purposes of the 90% of gross
income from qualified sources requirement, as discussed above.

The Developing Markets Growth Fund and International Growth Fund may purchase
the securities of certain foreign investment funds or trusts called passive
foreign investment companies. Currently, such funds are the only or primary
means by which the Funds may invest in Hungary and India. In addition to bearing
their proportionate share of the Developing Markets Growth Fund's and
International Growth Fund's expenses (management fees and operating expenses),
shareholders will also bear indirectly similar expenses of such funds. Capital
gains on the sale of such holdings will be deemed to be ordinary income
regardless of how long the Fund holds its investment. In addition, the
Developing Markets Growth Fund and International Growth Fund may be subject to
corporate income tax and an interest charge on certain dividends and capital
gains earned from these investments, regardless of whether such income and gains
are distributed to shareholders.

The foregoing relates only to federal income taxation and is a general summary
of the federal tax law in effect as of the date of this Statement of Additional
Information.

LIMITATION OF DIRECTOR LIABILITY
- --------------------------------------------------------------------------------

Under Minnesota law, each director of the Funds owes certain fiduciary duties to
the Funds and to their shareholders. Minnesota law provides that a director
"shall discharge the duties of the position of director in good faith, in a
manner the director reasonably believes to be in the best interest of the
corporation, and with the care an ordinarily prudent person in a like position
would exercise under similar circumstances." Fiduciary duties of a director of a
Minnesota corporation include, therefore, both a duty of "loyalty" (to act in
good faith and act in a manner reasonably believed to be in the best interests
of the corporation) and a duty of "care" (to act with the care an ordinarily
prudent person in a like position would exercise under similar circumstances).
Minnesota law authorizes corporations to eliminate or limit the personal
liability of a director to the corporation or its shareholders for monetary
damages for breach of the fiduciary duty of "care". Minnesota law does not,
however, permit a corporation to eliminate or limit the liability of a director
(i) for any breach of the directors' duty of "loyalty" to the corporation or its
shareholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for authorizing a
dividend, stock repurchase or redemption or other distribution in violation of
Minnesota law or for violation of certain provisions of Minnesota securities
laws or (iv) for any transaction from which the director derived an improper
personal benefit. The Articles of Incorporation of the Company limit the
liability of directors to the fullest extent permitted by Minnesota statutes,
except to the extent that such liability cannot be limited as provided in the
Investment Company Act of 1940 (which Act prohibits any provisions which purport
to limit the liability of directors arising from such directors' willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of their role as directors).

Minnesota law does not eliminate the duty of "care" imposed upon a director. It
only authorizes a corporation to eliminate monetary liability for violations of
that duty. Minnesota law, further, does not permit elimination or limitation of
liability of "officers" to the corporation for breach of their duties as
officers (including the liability of directors who serve as officers for breach
of their duties as officers). Minnesota law does not permit elimination or
limitation of the availability of equitable relief, such as injunctive or
rescissionary relief. Further, Minnesota law does not permit elimination or
limitation of a director's liability under the Securities Act of 1933 or the
Securities Exchange Act of 1934, and it is uncertain whether and to what extent
the elimination of monetary liability would extend to violations of duties
imposed on directors by the Investment Company Act of 1940 and the rules and
regulations adopted under such Act.

The Funds are not required under Minnesota law to hold annual or periodically
scheduled meetings of shareholders. Minnesota corporation law provides for the
Board of Directors to convene shareholder meetings when it deems appropriate.
However, the Funds intend to hold meetings of shareholders annually. In
addition, if a regular meeting of shareholders has not been held during the
immediately preceding fifteen months, a shareholder or shareholders holding
three percent or more of the voting shares of the Funds may demand a regular
meeting of shareholders by written notice of demand given to the chief executive
officer or the chief financial officer of the Funds. Within ninety days after
receipt of the demand, a regular meeting of shareholders must be held at the
expense of the Funds. Irrespective of whether a regular meeting of shareholders
has been held during the immediately preceding fifteen months, in accordance
with Section 16(c) under the 1940 Act, the Board of Directors of the Funds shall
promptly call a meeting of shareholders for the purpose of voting upon the
question of removal of any director when requested in writing so to do by the
record holders of not less than 10 percent of the


                                       36
<PAGE>


outstanding shares. Additionally, the 1940 Act requires shareholder votes for
all amendments to fundamental investment policies and restrictions and for all
investment advisory contracts and amendments thereto. The Funds will assist in
communications with other shareholders as required by Section 16(c) of the 1940
Act.

BOND RATINGS
      MOODY'S INVESTORS SERVICE, INC.
      -------------------------------
      Aaa   Judged to be the best quality, carry the smallest degree of
            investment risk
      Aa    Judged to be of high quality by all standards
      A     Possess many favorable investment attributes and are to be
            considered as higher medium grade obligations
      Baa   Medium grade obligations. Lack outstanding investment
            characteristics.
      Ba    Judged to have speculative elements. Protection of interest and
            principal payments may be very moderate.
      B     Generally lack characteristics of a desirable investment. Assurance
            of interest and principal payments over any long period of time may
            be small.
      Caa   May be present elements of danger with respect to principal or
            interest or may be in default
      Ca    Represent obligations which are speculative in a high degree. Often
            in default.
      C     Lowest class of bonds and issued regarded as having extremely poor
            prospects of attaining any real investment standing.
      Moody's also applies numerical indicators, 1, 2, and 3, to rating
      categories Aa through Ba. The modifier 1 indicates that the security is in
      the higher end of the rating category; the modifier 2 indicates a
      mid-range ranking; and 3 indicates a ranking toward the lower end of the
      category.

      STANDARD & POOR'S CORPORATION
      -----------------------------
      AAA   Highest grade obligations and possess the ultimate degree of
            protection as to principal and interest
      AA    Also qualify as high grade obligations, and in the majority of
            instances differ from AAA issues only in small degree
      A     Regarded as upper medium grade, have considerable investment
            strength but are not entirely free from adverse effects of changes
            in economic and trade conditions, interest and principal are
            regarded as safe
      BBB   Considered investment grade with adequate capacity to pay interest
            and repay principal.
      BB    Judged to be speculative with some inadequacy to meet timely
            interest and principal payments.
      B     Has greater vulnerability to default than other speculative grade
            securities. Adverse economic conditions will likely impair capacity
            or willingness to pay interest and principal.
      CCC   Has a vulnerability to default and is dependent upon favorable
            business, financial and economic conditions to meet timely payment
            of interest and repayment of principal.
      CC    Applied to debt subordinated to senior debt
      C     Applied to debt subordinated to senior debt that is assigned an
            actual or implied CCC debt rating

      above rating categories AA through BB. The indicators show relative
      standing within the major rating categories.

      FITCH IBCA
      ----------
      AAA   Highest credit quality with exceptional ability to pay interest and
            repay principal
      AA    Investment grade and very high credit quality ability to pay
            interest and repay principal is very strong, although not quite as
            strong as AAA
      A     Investment grade with high credit quality. Ability to pay interest
            and repay principal is strong.
      BBB   Investment grade and has satisfactory credit quality. Adequate
            ability to pay interest and repay principal.
      BB    Considered speculative. Ability to pay interest and repay principal
            may be affected over time by adverse economic changes.
      B     Considered highly speculative. Currently meeting interest and
            principal obligations, but probability of continued payment reflects
            limited margin of safety.
      CCC   Identifiable characteristics which if not remedied may lead to
            default. Ability to meet obligations requires an advantageous
            business and economic environment.
      CC    Minimally protected bonds. Default in payment of interest and/or
            principal seems probable over time.
      C     Imminent default in payment of interest or principal
      + and - indicators indicate the relative position within the rating
      category, but are not used in AAA category.

          CHAIRMAN'S LETTER

Dear Fellow Shareholders:

   A strong year-end rally capped another year of excellent returns for domestic
equity indices. Despite the significant rise in interest rates in 1999, the
Standard & Poor's 500 Index posted gains of over 20% for a 5th consecutive year.

Economic Overview

   December represented the 106th month of U.S. economic expansion, a period
characterized by strong economic growth and moderate inflation. Although there
was great debate over the potential Y2K impact in fourth quarter GDP, very
little evidence has emerged that the U.S economy slowed down from the rate
achieved during the first three quarters of 1999. We forecast over 5.5% GDP
growth in the fourth quarter, and as we examine momentum in key components
underlying the GDP calculation, it is very difficult to see how a major slowdown
will occur over the intermediate term. Strong employment and consumer confidence
levels have buoyed the largest component of GDP (personal consumption
expenditures) to consistent year-over-year growth of over 5.0%. Non-residential
fixed investment continues to be strong, and it appears that government spending
is on the rise. Finally, a strengthening global economy may support some
improvement in net exports, which have been the biggest drag on GDP growth. Our
only cautionary observation relates to the fact that consumer expenditures
continue to outpace personal income gains, and consumer borrowing has risen
sharply in recent months. Federal Reserve Chairman, Alan Greenspan, has
expressed similar concerns on this issue, specifically citing the "wealth
effect" created by the rising prices of homes and financial assets. Given
increasing evidence of the link between the equity markets and consumer
confidence (and spending), we believe that the Federal Reserve will apply the
brakes slowly to avoid any major disruption in the financial markets. Our
conclusion is that there will be "more of the same" in the year ahead;
therefore, we project full year GDP growth in the area of 4.0%.
   Prospects for another year of solid global economic growth have pressured
interest rates upward in recent months, but we believe inflation pressures will
remain modest. While year-over-year consumer price index (CPI) data have
accelerated throughout the year, we believe this is largely commodity-related
and, specifically, oil-related. Excluding food and energy, the "core" rates of
both producer and consumer price inflation have been rising at a modest 2.0%
rate. We project a slight increase in the CPI in 2000, rising to 2.6% from 2.2%
in 1999. Part of our longer-term optimism on inflation stems from the rapid
introduction of new technology and the secular trend to substitute capital for
labor. In a recent speech before the Economic Club of New York, Mr. Greenspan
acknowledged the powerful impact that technology is having on the economy,
stating "What should be indisputable is that a number of new technologies that
evolved from the cumulative innovations of the past half century have now begun
to bring about awesome changes in the way goods and services are distributed to
final users." Global spending on technology, particularly the rapid adoption of
the Internet, is having the combined effect of increasing labor productivity,
while limiting price increases.
   In spite of our optimism about inflation on a secular basis, we believe the
Federal Reserve is likely to raise rates as much as an additional one-half
percentage point in 25 basis point increments starting with the early February
Federal Open Markets Committee meeting. Tight labor markets in a rapidly growing
domestic economy concern Federal Reserve officials. Mr. Greenspan noted that,
despite the structural changes occurring in the economy that have to this point
contained inflation, the Federal Reserve's goal is "to extend the expansion by
containing its imbalances and avoiding the very recession that would complete a
business cycle."
   With regard to U.S. fiscal policy, we believe that the fiscal 2000 budget
surplus will be considerably higher than the Clinton Administration's current
forecast of $142.5 billion. Our own forecast is $180-185 billion. Consequently,
President Clinton has advanced a number of spending plans focussed on education
and health care, while Republican presidential candidates are favoring a
balanced package including tax cuts. Spending is continuing to rise at faster
rates at the state and local government level than they had been previously. We
are monitoring all government spending patterns closely because of their
potentially inflationary implications.
   In stark contrast to a year ago, economic growth outside the U.S. appears to
be on solid footing. We are estimating global GDP growth of 3.0% in 2000, ahead
of an estimated

2.0% in 1999. Our optimistic view is based upon the following: European economic
growth is beginning to accelerate, the recession in Japan is coming to an end,
other Asian economies are recovering very quickly, and stronger commodity prices
and lower interest rates are aiding recovery in Latin America.

Equity Strategy Summary

   A strong year-end rally helped push domestic equity indices markedly higher
in 1999, continuing the string of exceptional financial asset returns in the
U.S. Over the last five years, the cumulative total return for the Standard &
Poor's 500 Index has been a remarkable 250%.
   1999 marked another year of wide dispersion among financial asset categories.
Stocks dramatically outperformed bonds, as investors shook off concerns over
higher interest rates and focussed on an improved outlook for corporate earnings
in the recovering global economy. Despite the strong performance of the U.S.
equity market, the U.S. ranked only 20th among the 33 largest markets worldwide.
   Within the U.S., 1999 marked the widest differential favoring growth over
value in the history of the Frank Russell Company indices. The relatively higher
weightings within the technology sector were responsible for much of the
outperformance of growth over value. The technology-laden NASDAQ OTC Composite
posted an exceptional return for the year, increasing 85.6%. We estimate that
703 of the roughly 4000 companies in the Index for the entire year doubled in
price over the course of 1999. This strong performance relative to other market
indices perhaps best symbolizes the performance differential between the "New
Economy" and "Old Economy" sectors within the equity market. The surge in
technology shares has left many observers wondering if the trend will continue.
We believe the answer is yes, but it is clear that higher valuations imply a
higher level of risk going forward. Our enthusiasm for this sector is supported
by surging technological innovation coupled with strong global demand for
productivity-enhancing technology. In a market environment that has continuously
rewarded strong earnings growth, we attribute much of our success in 1999 to our
focus on enhancing projected earnings growth rates within our equity portfolios.
A sizable portfolio weighting in the fast-growing technology sector has been a
key factor in producing projected earnings growth rates that are at more than
twice that of the Standard & Poor's 500 Index based on 2000 estimates.
   Internationally, we remain optimistic on the outlook for European equity
markets due to strengthened economic fundamentals, a widening corporate movement
to enhance productivity and profitability, and the growth of a capital
markets/equity culture in Europe. We are also positive on investment
opportunities in Japan, as the equity market posted strong results driven by
strong capital inflows, government fiscal stimulus, and corporate restructuring.
We are somewhat cautious on the near-term prospects for Latin America markets.
Political instability remains a key concern, and both Brazil and Argentina are
struggling with budget deficit reductions.
   In general, we believe greatly improving economic conditions around the world
will continue to provide attractive investment opportunities in the year ahead.

With best wishes,

/s/ Eugene C. Sit

PERFORMANCE SUMMARY - STOCK FUNDS

   Domestically, equity markets generated strong results during in 1999. Strong
corporate earnings growth and surging performance in the technology sector was
enough to overcome a significant rise in interest rates that occurred throughout
the year. 1999 marked an unprecedented 5th consecutive year of returns over 20%
for the equity market (as measured by the Standard & Poor's 500 Index). This was
also a record 9th consecutive year of positive returns for the market.
   Smaller capitalization issues showed improved relative performance in 1999.
For the first time since 1994, the Russell 2000 Index return (+21.3%) was
modestly higher than the return for the S&P 500 Index (+21.0%). Growth stocks
outperformed value issues across the capitalization spectrum. The large cap
Russell 1000 Growth Index bested the Russell 1000 Value Index by nearly twenty
six percentage points during 1999, with returns of +33.2% and +7.4%,
respectively. The growth/value performance differential was even greater among
small cap issues, as the Russell 2000 Growth returned +43.1%, while the Russell
2000 Value returned -1.5%.
   The technology sector was the best performing sector in the market in 1999 by
a wide margin. We estimate that the combined returns of the technology sectors
were +73.7% and +113.9% in the S&P 500 Index and the Russell 2000 Index,
respectively. Sectors that lagged the market over the past year include
financial services, utilities, health services and consumer non-durables.
Continuing the trend that has existed over the past few years, a select group of
large stocks, mostly within technology, have disproportionately driven indices
higher. We estimate that just seven stocks contributed half of the total return
for the S&P 500 Index in 1999.
   International equity market indices also moved higher in 1999. In fact, every
major regional equity market delivered double-digit investment returns, largely
due to an improving outlook for the global economy and corporate profits.
Emerging markets benefited the most from this improving economic outlook, as the
MSCI Pacific ex-Japan Index rose 42.6% and the MSCI Latin America Free Index
increased 55.5%. Japan's equity market turned in its strongest performance of
the decade, gaining 61.5%. Investment returns in Europe were somewhat mixed in
1999 (although generally positive), as the MSCI Europe Index posted a return of
+15.9%.

[PHOTO]   SIT BALANCED FUND
          SIX MONTHS ENDED DECEMBER 31, 1999
          ----------------------------------------------------------------------

   The Sit Balanced Fund's +14.1% return over the past six months was strong on
both an absolute and relative basis and compared favorably to the +2.7% return
for the Lipper Balanced Fund Index. The Fund's 1999 return of +20.2% ranked in
the 6th percentile of the 449 balanced funds ranked by Lipper Analytical
Services. For the 3-year and 5-year periods, the Fund ranked in the 7th
percentile out of 333 funds and the 9th percentile out of 223 funds.
   As of December 31, 1999, the asset allocation of the Fund was 60.9% equities
(up from 54.6% at the end of June), 35.0% fixed income securities (down from
36.9%), and 4.1% cash and other net assets.
   A strong year-end rally helped push equity market returns solidly higher over
the past six months. Investors were able to shake off inflation and interest
rate concerns, and focus on the recovering global economy and resultant
acceleration in corporate earnings. Growth stocks continue to outperform value
issues, largely fueled by the surging technology sector. The Fund significantly
benefited from an overweighted position in the technology sectors, with greater
sector weights in both electronic technology and technology services than six
months ago. Sector weighting decreases occurred in health services and health
technology. Strong earnings growth continues to be a distinct attribute of the
Fund, with an average projected 1-year and 5-year earnings growth rate for
companies held in the Fund of 25.0% and 23.5%, respectively. This compares to a
projected earnings growth rate for the S&P 500 Index of 9.1% for 2000 and 10.0%
for the next five years.
   While the outlook for improving corporate earnings and a strong global
economy provided support for the equity markets over the past year, bond prices
fell over continued fears about excessive economic growth and a potential
acceleration in inflation. Yields on 30-year U.S. Treasury bonds rose 47 basis
points over the last six months and 140 basis points for the 1999 calendar year,
with the yield at year-end standing at 6.48%. The most significant recent change
in fixed income strategy occurred toward the end of 1999, as we began to
emphasize corporate securities over U.S. Treasuries, and relative yields on
corporates became attractive as investors' Y2K fears caused a temporary flight
to safety in Treasuries. Going forward, we believe interest rates will creep
somewhat higher over the near-term.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The Sit Balanced Fund's dual objectives are to seek long-term growth of
capital consistent with the preservation of principal and to provide regular
income. It pursues its objectives by investing in a diversified portfolio of
stocks, bonds and short-term instruments. The Fund may emphasize either equity
securities, fixed-income securities, or short-term instruments or hold equal
amounts of each, dependent upon the Adviser's analysis of market, financial and
economic conditions.

     The Fund's permissible investment allocation is: 40-60% in equity
securities, 40-60% in fixed-income securities, and up to 20% in short-term
fixed-income instruments. At all times at least 25% of the assets will be
invested in fixed-income senior securities.

[PHOTO]   SIT LARGE CAP GROWTH FUND
          SIX MONTHS ENDED DECEMBER 31, 1999
          ----------------------------------------------------------------------
          SENIOR PORTFOLIO MANAGERS
          PETER L. MITCHELSON, CFA * ROGER J. SIT * RONALD D. SIT, CFA

   The Sit Large Cap Growth Fund posted strong results for the last six months
and full calendar year of 1999, increasing 22.8% and 33.4%, respectively. By
comparison, the S&P 500 Index return was +7.7% for the final six months of 1999
and +21.0% for the calendar year.
   A strong year-end rally capped another year of solid returns for most major
stock indices. Although concerns over inflation and a significant increase in
long-term interest rates caused volatility along the way, strong corporate
earnings provided key support for the advance in the equity markets. Growth
stocks continued their strong relative performance, largely due to the continued
exceptional performance of the technology sector. Although the strong
performance of technology issues has led to increased valuation for the sector,
we believe that future earnings growth will be significantly higher for these
companies than for the broader market. The rapid pace of technological
innovation is fueling robust corporate and consumer spending on information
technology, providing for a broad variety of investment opportunities in several
areas, including telecommunications, networking, E-commerce, semiconductors and
software applications. Since we believe that the technology boom is far from
over, the Fund continues to be significantly overweighted in the technology
sector.
   The most significant sector weighting increases over the past six months
include electronic technology, technology services and utilities through the
purchases of Nokia, QUALCOMM, Global Crossing, First Data, Xilinx and JDS
Uniphase. Sector weighting decreases occurred in health technology, health
services and retail trade through the reduction or elimination of positions in
McKesson HBOC, Gap, Lowe's, American Home Products, Eli Lilly and
Schering-Plough. As of December 31st, the Fund was 97% invested in equities, up
from 93% six months ago.
   Securities in the Fund continue to exhibit high projected earnings growth
rates. We estimate that companies within the Fund will grow earnings in excess
of 25% in the coming year, well above the 9% growth projection for the S&P 500
Index. In addition to strong fundamentals, attractive relative valuations for
fast-growing companies give us optimism about the Fund's outlook.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Large Cap Growth Fund is to maximize long-term capital
appreciation. The Fund pursues this objective by investing primarily in common
stocks of growth companies with a capitalization of $5 billion or more at the
time of purchase.

[PHOTO]   SIT REGIONAL GROWTH FUND
          SIX MONTHS ENDED DECEMBER 31, 1999
          ----------------------------------------------------------------------
          EUGENE C. SIT, CFA, SENIOR PORTFOLIO MANAGER

   The Sit Regional Growth Fund rose +7.7% over the second half of 1999, equal
to the +7.7% return for the S&P 500 Index.

   The Fund's longer term record relative to the S&P 500 Index has been
negatively impacted by the underweighting of the very large companies outside of
the Fund's regional focus, as a select few stocks have disproportionately driven
the Index higher. Recent evidence supporting a broadening market, however, bodes
well for the Fund's prospects, given that the Fund's weighted market
capitalization remains well below that of the S&P 500 Index.

   Strong earnings growth continues to be a primary focus of the portfolio. We
project earnings growth of +21.9% over the next year and +19.4% over the next
five years, which compares quite favorably to the +9.1% and +10.0% projected
growth rates for the S&P 500 Index over the same time periods. We believe that
the valuations of companies held in the Fund are highly attractive, especially
in light of superior relative growth rates. For example, the weighted
price-to-earnings ratio for companies held in the Fund is 30x (based on 2000
estimates), which is only slightly higher than the S&P 500 Index multiple of
29x. We believe this valuation is compelling, given that the projected earnings
growth rate for companies held in the Fund is twice that of the S&P 500 Index
over the next year.

   As of December 31st, the Fund was 98% invested in equity securities, up from
95% six months ago. Significant sector weighting changes over the past six
months include increases in electronic technology and consumer services, while
retail trade and health technology had the largest decrease. Given the Fund's
emphasis on growth companies and the dynamic changes occurring within our
economy, the electronic technology and technology services sectors are the
heaviest weighted sectors within the Fund.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Fund is to maximize long-term capital appreciation.
The Fund pursues this objective by investing primarily in common stocks of
companies with their headquarters in Minnesota, Iowa, Missouri, North Dakota,
South Dakota, Nebraska, Kansas, Wisconsin, Illinois, Michigan, Indiana, and

[PHOTO]   SIT MID CAP GROWTH FUND
          SIX MONTHS ENDED DECEMBER 31, 1999

   The Sit Mid Cap Growth Fund returned +51.9% during the second half of 1999
and produced a calendar 1999 return of +70.7%. This compares favorably with the
+7.3% semi-annual return and +14.7% calendar return for the S&P MidCap 400
Index.
   Over the past year, small and mid cap stocks posted improved returns relative
to larger cap issues, we attribute this outperformance to extreme undervaluation
and renewed investor confidence in the global economic environment. In addition,
the accelerating pace of change within technology has led to surging performance
of many dynamic small- and mid-sized technology companies. This sector's
performance has been strong enough to almost single-handedly drive most small
and mid cap indices higher. Indeed, the Fund's excess return over the S&P MidCap
400 Index is largely attributable to its overweighted position and favorable
stock selection within the electronic technology and technology services
sectors.
   These sectors within the Fund posted a combined return of nearly 100% over
the past six months. Several large holdings, including JDS Uniphase, QUALCOMM,
Applied Micro Circuits and Check Point Software, posted returns of over +200%
for the period. Although such remarkable performance cannot be expected to
persist in the future, we believe the fundamentals underlying this strong stock
performance support continued overweighted position in the technology sectors.
   Along with the Fund's positioning in other high growth sectors, technology
investments are a key element underlying the strong projected earnings growth
for companies held in the Fund, which we currently estimate at 37.0% for 2000
and 33.2% over the next five years. This compares quite favorably with the S&P
500 Index estimated 2000 earnings growth of 9.1% and 5-year projected growth
rate of 10.0%.
   In terms of sector weightings, electronic technology, consumer services and
technology services showed the largest increases over the past six months. New
purchases included QUALCOMM, International Speedway, Siebel Systems and VERITAS
Software. Significant sector weighting decreases occurred in health technology,
retail trade and finance through the sale of Biogen, Boston Scientific, Elan,
Staples and Mutual Risk Management. As of December 31st, the Fund was 97%
invested in equity securities.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Sit Mid Cap Growth Fund is to maximize long-term
capital appreciation. The Fund pursues this objective by investing primarily in
the common stocks of growth companies with a capitalization of $2 billion to $15
billion at the time of purchase.

[PHOTO]   SIT INTERNATIONAL GROWTH FUND REVIEW
          SIX MONTHS ENDED DECEMBER 31, 1999
          ----------------------------------------------------------------------
          SENIOR PORTFOLIO MANAGERS
          EUGENE C. SIT, CFA * ANDREW B. KIM, CFA * ROGER J. SIT

   The Sit International Growth Fund gained 48.2% for the six months ended
December 31, 1999 compared with the MSCI EAFE Index return of +22.1% and the
Lipper International Fund Index return of +28.9%. The Fund's return for 1999 was
+50.8% compared with gains of 27.0% for the MSCI Index and 37.8% for the Lipper
Index. The Fund's outperformance had been primarily led by the portfolio's
Japanese and European holdings. The sector leaders continued to be information
technology services, telecommunications, technology and retailers.
   The returns for the Fund's European holdings increased substantially in the
December quarter, up 43%, after being up only 1% in the September quarter.
European markets reacted favorably over the last three months, as investor
sentiment has become more positive. Structural and financial reforms are being
proposed and implemented. Merger and acquisition activity more than doubled in
1999 as European companies sought pan-European alliances and cross border deals
with rivals. Consolidation in the telecommunications and financial service
sectors is expected to continue. Lastly, companies are benefiting from
increasing exports, supported by the weak euro, as global growth accelerates. We
believe European equities will continue to outperform as economies improve,
corporate restructuring and consolidation continues, and Europe closes the
technology gap with the U.S.
   The Fund's Japanese holdings continued to perform strongly, up 36.9% in the
December quarter, on top of the 36.8% in the preceding quarter. Foreign and
domestic investors have taken an optimistic view as corporate restructuring
gathers speed. As with Europe, focus is on the global technology boom
concentrated on telecommunications, Internet and service-related industries. Our
Japanese portfolio has greatly benefited by the price appreciation in these
sectors. Our non-Japan Asia investments remain directed toward semiconductor and
contract manufacturers.
   We expect to maintain the Fund's European weighting in the mid 50% area and
the Japan weighting around 30% as we begin the new calendar year. We believe
capital flows will favor these markets. We also intend to retain our sector
preferences in those industries that have long-term growth opportunities:
technology, telecommunications and service.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Sit International Growth Fund is to achieve long-term
growth of capital by investing in equity securities of issuers domiciled outside
the United States. The Fund's investment objective reflects the belief that
long-term investment planning should include the investment opportunities that
exist outside the U.S.

     The Fund selects its investments based on the characteristics of the
particular markets and economies of the countries in which it invests. Emphasis
is placed on identifying securities of companies believed to be undervalued in
the marketplace in relation to factors such as the company's revenues, earnings,
assets and long-term competitive position which over time will enhance the
equity value of the company.

[PHOTO]   SIT SMALL CAP GROWTH FUND
          SIX MONTHS ENDED DECEMBER 31, 1999
          ----------------------------------------------------------------------
          EUGENE C. SIT, CFA, SENIOR PORTFOLIO MANAGER

   The Sit Small Cap Growth Fund returned +83.9% over the last six months and
+108.6% for the calendar year. This compares favorably to the six-month return
of +11.0% and the 1999 return of +21.3% for the Russell 2000 Index. The Fund's
annual return ranked in the 12th percentile of the 263 small cap growth funds
ranked by Lipper Analytical Services. For the 3-year and 5-year periods, the
Fund ranked in the 25th percentile out of 165 funds and 9th percentile out of 91
funds, respectively.
   In 1999, small stocks rebounded after three years of underperformance
relative to larger capitalization issues. Given that there is still a
significant valuation gap between large and small cap stocks, we believe
smaller-capitalization outperformance may be in the early stages. The technology
sector remains a key driver of small stock performance, as innovation within the
"new economy" is opening up investment opportunities in dynamic industries such
as telecommunications, the Internet and biotechnology. A significant
overweighting in the technology sector was a key factor underlying the Fund's
strong performance relative to the Russell 2000 Index. We estimate that over the
past six months, the Fund's positions in the electronic technology and
technology services sectors returned +152.0% and +103.7%, respectively, compared
to the +59.4% and +86.5% return for the same sectors within the Russell 2000
Index. Four of the Fund's largest positions, including JDS Uniphase, Applied
Micro Circuits, SDL and Sapient, posted six-month returns in excess of 200%.
Given the dynamic investment opportunities within the sector, the Fund will
continue to hold a significantly overweighted position across many different
industries within technology.
   We believe the equity market's focus on strong earnings growth has been a key
element behind the Fund's performance. The projected earnings growth rates for
companies held in the Fund is 37.7% for 2000 and 35.6% over the next five years.
This compares to a growth rate of 9.1% and 10.0% over the next 1-year and 5-year
periods, respectively, for the S&P 500.
    The most significant sector weighting increases occurred in the electronic
technology and health technology sectors. Weightings decreased in the finance
and utilities sectors. As of December 31, 1999, the Fund was 95.5% invested in
equity securities.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Sit Small Cap Growth Fund is to maximize long-term
capital appreciation. The Fund pursues this objective by investing primarily in
the common stocks of small growth companies that have a capitalization of $2.5
billion or less at the time of purchase.

     In addition, the Fund may purchase securities convertible into common
stocks, preferred stocks and warrants. The Fund may invest in securities not
listed on a national securities exchange but generally such securities will have
an established over-the-counter market.

[PHOTO]   SIT SCIENCE AND TECHNOLOGY GROWTH FUND
          SIX MONTHS ENDED DECEMBER 31, 1999
          ----------------------------------------------------------------------
          EUGENE C. SIT, CFA, SENIOR PORTFOLIO MANAGER

   The Sit Science and Technology Growth Fund returned +69.0% over the last six
months and +86.0% for calendar year 1999. The S&P 500 Index return was +7.7% and
+21.0% over the past six-month and twelve-month periods, respectively. The
six-month return for the Pacific Stock Exchange (PSE) Technology 100 Index was
+62.0%, while the 1999 calendar year return was +116.4%.
   Science and technology stocks posted excellent returns in 1999, driven by the
remarkable surge in technological innovation combined with accelerating
worldwide spending on information technology. Enthusiasm for technology was
broad-based. The explosive growth in e-commerce, rapid upgrading of
telecommunications and networking infrastructure, the cyclical recovery of the
semiconductor industry, and rapid new product development occurring within
biotechnology are all examples of this enthusiasm. We continue to believe that
the technology boom is in its early stages, with continued innovation and strong
global demand for productivity-enhancing technology providing strong underlying
support for companies within the Fund.
   Returns in the electronic technology sector were particularly strong over the
last six months, producing an estimated return of nearly +85% over the period.
SDL, Applied Micro Circuits, QUALCOMM, and PMC-Sierra were among the strongest
performers in the electronic technology sector, increasing 327%, 209%, 395%, and
172%, respectively. Biotechnology companies (Protein Design, up 215%, and IDEC
Pharmaceuticals, up 155%) and software providers (Checkpoint Software, up 271%
and I2 Technologies, up 353%) were other important contributors to the Fund's
semi-annual performance.
   There were only minor changes in sector weightings over the past six months,
with a modest increase in the electronic technology and technology services
sectors, and a slight decrease in the health care sector weighting. Although our
commitment to the health care sector has been a detriment to returns since the
inception of the Fund, particularly relative to purer technology indices like
the PSE Technology 100 Index, we believe that compelling fundamentals and
favorable valuations exist within this sector. As of December 31st, the Fund was
97% invested in equity securities, down from 99% six months ago.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Fund is to maximize long-term capital appreciation.
The Fund pursues this objective by investing primarily in common stocks of
companies which Sit Investment Associates, Inc. expects to benefit from the
development, improvement, advancement and use of science and technology. During
normal market conditions, at least 80% of the Fund's total assets will be
invested in such securities. The Fund emphasizes securities of companies that
the adviser believes have potential for long-term capital growth.

[PHOTO]   SIT DEVELOPING MARKETS GROWTH FUND
          SIX MONTHS ENDED DECEMBER 31, 1999
          ----------------------------------------------------------------------
          EUGENE C. SIT, CFA, SENIOR PORTFOLIO MANAGER
          ANDREW B. KIM, CFA, SENIOR PORTFOLIO MANAGER

   The Sit Developing Markets Growth Fund outperformed the MSCI Emerging Markets
Free Index and the Lipper Emerging Markets Index for the six months ended
December 31, 1999. The Fund gained 42.1% versus 18.3% for the MSCI Index and
25.1% for the Lipper Index. As the global rally continued in companies perceived
to be internet-related, the Fund benefited from its overweighted position and
stock selection in the telecommunications and technology sectors.
   The Fund continues to hold an overweighted position in Asia, with a 60.3%
weighting as of December 31st vs. 38.2% for the Index. Higher-than-expected GDP
and export growth figures announced during the past six months demonstrated that
the economic rebound in the region has been sustained. The recent WTO agreement
between China and the U.S. bodes well for the Asian markets as increased
economic ties between China and the rest of the world will create new investment
opportunities for Asian firms and reduce the security risks in the region.
During the past six months, we added three Malaysian stocks--Maybank, Commerce
Asset, and Resorts World--in anticipation of economic reform in Malaysia and the
abolition of its exit tax on foreign investment.
   Over the past six months, the Fund increased its weighting in Latin America
to 13.9% vs. 30.5% for the Index. Rebounding GDP growth, rising commodity
prices, and a recovery in corporate earnings suggest that fundamentals are
improving. Our purchases of Brazilian retailer, Grupo Pao de Acucar, and Grupo
Televisa, the leading Mexican media conglomerate, reflect our more optimistic
view on the region. We will be making additional purchases in Latin America in
the near future if these positive trends continue.
   We are maintaining an underweighted position in Emerging-Europe, Middle East
and Africa of 17.2% vs. 31.2% for the Index. Our holdings in these regions
continue to focus on globally-competitive technology firms, such as South
African systems integrator Dimension Data and Comverse Technology, an Israeli
firm specializing in enhanced wireless services.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Sit Developing Markets Growth Fund is to maximize
long-term capital appreciation. The Fund pursues this objective by investing in
equity securities of companies located or otherwise operating in a developing
market.

     Developing markets tend to be less economically developed regions of the
world. General characteristics also include a high demand for capital
investment, a high dependence on export markets for their major industries, a
need to develop basic economic infrastructures, rapid economic growth and lower
degrees of political stability. Investors should carefully consider the risks
associated with developing markets such as currency flucuations, high
volatility, illiquidity and the possibility of political instability.

      Growth Fund
      --------------------------------------------------------------------------

Significant accounting policies followed by the Funds are summarized below:

INVESTMENTS IN SECURITIES

Investments in securities traded on national or international securities
exchanges are valued at the last reported sales price prior to the time when
assets are valued. Securities traded on the over-the-counter market are valued
at the last reported sales price or if the last sales price is not available at
the last reported bid price. The sale and bid prices are obtained from
independent pricing services. Debt securities maturing more than 60 days are
priced by an independent pricing service. When market quotations are not readily
available, or securities can not be valued by the pricing service, securities
are valued at fair value as determined in good faith using procedures
established by the Board of Directors, which may include dealer supplied
valuations. Debt securities maturing in less than 60 days when acquired, or
which subsequently are within 60 days of maturity, are valued at amortized cost.

Security transactions are accounted for on the date the securities are purchased
or sold. Securities gains and losses are calculated on the identified-cost
basis. Dividend income is recorded on the ex-dividend date or upon the receipt
of ex-dividend notification in the case of certain foreign securities. Interest,
including level-yield amortization of long-term bond premium and discount, is
recorded on the accrual basis.

<PAGE>


ILLIQUID SECURITIES

Each Fund currently limits investments in illiquid securities to 15% of net
assets. At December 31, 1999, the Developing Markets Growth Fund held
investments in securities deemed illiquid by the investment adviser. The
aggregate value of such securities at December 31, 1999, was $72,978,
representing 0.5% of the Fund's net assets. Pursuant to the guidelines adopted
by the Board of Directors, certain unregistered securities are determined to be
liquid and are not included within the limitation specified above.

FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS

The market value of securities and other assets and liabilities denominated in
foreign currencies for Developing Markets Growth Fund and International Growth
Fund are translated daily into U.S. dollars at the closing rate of exchange.
Purchases and sales of securities, income and expenses are translated at the
exchange rate on the transaction date. Dividend and interest income includes
currency exchange gains (losses) realized between the accrual and payment dates
on such income. Exchange gains (losses) may also be realized between the trade
and settlement dates on security and forward contract transactions. For
securities denominated in foreign currencies, the effect of changes in foreign
exchange rates on realized and unrealized gains or losses is reflected as a
component of such gains or losses.

The Developing Markets Growth and International Growth Funds may enter into
forward foreign currency exchange contracts for operational purposes and to
protect against adverse exchange rate fluctuation. The net U.S. dollar value of
foreign currency underlying all contractual commitments held by the Funds and
the resulting unrealized appreciation or depreciation are determined using
foreign currency exchange rates from an independent pricing service. The Funds
are subject to the credit risk that the other party will not complete the
obligations of the contract.

As of December 31, 1999, the International Growth Fund had entered into an open
forward currency exchange contract with an exchange date of January 12, 2000.
The net unrealized depreciation of $2,023,930 for this contract is included in
the accompanying financial statements.

                                                         U.S. Dollar Value as of
                                                             December 31, 1999

      Net Unrealized Depreciation                               $ 2,023,930
                                                                -----------

FEDERAL TAXES

The Funds' policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of its
taxable income to shareholders. Therefore, no income tax provision is required.
Also, in order to avoid the payment of any federal excise taxes, the Funds will
distribute substantially all of their net investment income and net realized
gains on a calendar year basis.

Net investment income and net realized gains may differ for financial statement
and tax purposes. The character of distributions made during the year for net
investment income or net realized gains may also differ from its ultimate
characterization for tax purposes. Also, due to the timing of dividend
distributions, the fiscal year in which amounts are distributed may differ from
the year that the income or realized gains (losses) were recorded by the Fund.

                                                                              49

SIT MUTUAL FUNDS
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS (CONTINUED)


For federal income tax purposes the Developing Markets Growth Fund has a capital
loss carryover of $3,697,984 at June 30, 1999 which, if not offset by subsequent
capital gains, will begin to expire in 2004. Also at June 30, 1999, the Small
Cap Growth, Science and Technology Growth, and Regional Growth Funds have
capital loss carryovers of $3,899,846, $332,937, and $67,482, respectively
which, if not offset by subsequent capital gains, will begin to expire in 2007.
It is unlikely that the Board of Directors will authorize a distribution of net
realized gains until the available capital loss carryovers are offset or expire.

DISTRIBUTIONS

Distributions to shareholders are recorded as of the close of business on the
record date. Such distributions are payable in cash or reinvested in additional
shares of the Funds' capital stock. Distributions from net investment income, if
any, are declared and paid quarterly for the Balanced Fund and declared and paid
annually for Regional Growth, Science and Technology Growth, Developing Markets
Growth, Small Cap Growth, International Growth, Mid Cap Growth, and Large Cap
Growth Funds. Distributions from net realized gains, if any, will be made
annually for each of the Funds.

CONCENTRATION OF INVESTMENTS

The Developing Markets Growth Fund may concentrate investments in countries with
limited or developing capital markets which may involve greater risks than
investments in more developed markets and the prices of such investments may be
volatile. The consequences of political, social or economic changes in these
markets may have disruptive effects on the market prices of the Fund's
investments and the income it generates, as well as the Fund's ability to
repatriate such amounts.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported results. Actual results could differ from those
estimates.

NOTE 2 - INVESTMENT SECURITY TRANSACTIONS

SIA is obligated to pay all of the Funds' expenses (excluding extraordinary
expenses, stock transfer taxes, interest, brokerage commissions and other
transaction charges relating to investing activities).

For the period November 1, 1996 through December 31, 2000 the Adviser has agreed
to limit the management fee (and, thereby, all Fund expenses, except those not
payable by the Fund as set forth above) of the Mid Cap Growth Fund to 1.00% of
the Fund's average daily net assets. For the period January 1, 1994 through
December 31, 2000, the Adviser has agreed to limit the management fee (and,
thereby, all Fund expenses, except those not payable by the Fund as set forth
above) of the International Growth Fund to 1.50% of the Fund's average daily net
assets. For the period January 1, 1998 through December 31, 2000 the Adviser has
agreed to limit the management fee (and, thereby, all fund expenses, except
those not payable by the Fund as set forth above) of the Regional Growth and
Science and Technology Growth Fund to 1.00% and 1.25%, respectively, of the
Fund's average daily net assets. After December 31, 2000, these voluntary fee
waivers may be discontinued by the Adviser in its sole discretion. During the
period ended December 31, 1999, for the Mid Cap Growth, International Growth,
Regional Growth, and Science and Technology Growth Funds, SIA voluntarily
absorbed an additional $517,751, $186,879, $9,228 and $22,037, respectively, in
expenses that were otherwise payable by the Funds.

As of December 31, 1999, the Large Cap Growth Fund, International Growth Fund,
Mid Cap Growth Fund, Small Cap Growth Fund, Regional Growth Fund, Science and
Technology Growth Fund, Developing Markets Growth Fund, and Balanced Fund had
invested $4,239,000, $7,427,000, $10,547,000, $4,719,000, $147,000, $612,000,
$1,137,000, and $544,000, respectively, in the Sit Money Market Fund. The terms
of such transactions were identical to those of non-related entities except
that, to avoid duplicate investment advisory fees, SIA remits to each Fund an
amount equal to all fees otherwise due to them under their investment management
agreement for the assets invested in the Sit Money Market Fund.

                                                                              51

(1)  Total investment return is based on the change in net asset value of a
     share during the period and assumes reinvestment of distributions at net
     asset value.

(2)  Percentages for periods ended December 31, 1999 and June 30, 1998 are
     adjusted to an annual rate. Total Fund expenses are contractually limited
     to 1.25% of average daily net assets. However, during the periods ended
     December 31, 1999, June 30, 1999 and 1998, the investment adviser
     voluntarily absorbed $9,228, $14,845 and $3,611, respectively, in expenses
     that were otherwise payable by the Fund. Had the fund incurred these
     expenses, the ratio of expenses to average daily net assets would have been
     1.25% for the periods ended December 31, 1999, June 30, 1999 and 1998, and
     the ratio of net investment income (loss) to average daily net assets would
     have been (0.39%), (0.29%) and 0.19%, respectively.

(1)  Total investment return is based on the change in net asset value of a
     share during the period and assumes reinvestment of distributions at net
     asset value.

(2)  Percentages for periods ended December 31, 1999 and June 30, 1998 are
     adjusted to an annual rate. Total Fund expenses are contractually limited
     to 1.50% of average daily net assets. However, during the periods ended
     December 31, 1999, June 30, 1999 and 1998, the investment adviser
     voluntarily absorbed $22,037, $22,008 and $4,655, respectively, in expenses
     that were otherwise payable by the Fund. Had the fund incurred these
     expenses, the ratio of expenses to average daily net assets would have been
     1.50% for the periods ended December 31, 1999, June 30, 1999 and 1998, and
     the ratio of net investment income (loss) to average daily net assets would
     have been (1.25%), (0.97%) and (0.46%), respectively.

                                                                              59

         Re:      Shares to be Issued Pursuant to Agreement and Plan of
                  Reorganization

Ladies and Gentlemen:

         We have acted as counsel to Sit Large Cap Growth Fund, Inc., a
Minnesota corporation ("Large Cap Fund"), in connection with the authorization
and proposed issuance of its common shares, par value $.01 per share (the
"Shares"). The Shares are to be issued pursuant to an Agreement and Plan of
Reorganization (the "Agreement"), by and between Large Cap Fund and Sit Mutual
Funds, Inc., a Minnesota corporation, the form of which Agreement is included as
Exhibit A to the Prospectus/Proxy Statement relating to the transactions
contemplated by the Agreement included in Large Cap Fund's Registration
Statement on Form N-14 filed with the Securities and Exchange Commission (the
"Registration Statement").

         In rendering the opinions hereinafter expressed, we have reviewed the
corporate proceedings taken by Large Cap Fund in connection with the
authorization and issuance of the Shares, and we have reviewed such questions of
law and examined copies of such corporate records of Large Cap Fund,
certificates of public officials and of responsible officers of Large Cap Fund,
and other documents as we have deemed necessary as a basis for such opinions. As
to the various matters of fact material to such opinions, we have, when such
facts were not independently established, relied to the extent we deem proper on
certificates of public officials and of responsible officers of Large Cap Fund.
In connection with such review and examination, we have assumed that all copies
of documents provided to us conform to the originals; that all signatures are
genuine; and that prior to the consummation of the transactions contemplated
thereby, the Agreement will have been duly and validly executed and delivered on
behalf of each of the parties thereto in substantially the form included in the
Registration Statement.

         Based on the foregoing, it is our opinion that the Shares, when issued
and delivered by Large Cap Fund pursuant to, and upon satisfaction of the
conditions contained in, the Agreement, will be duly authorized, validly issued,
fully paid and non-assessable.

         In rendering the foregoing opinions (a) we express no opinion as to the
laws of any jurisdiction other than the State of Minnesota; and (b) we have
assumed, with your concurrence, that the conditions to closing set forth in the
Agreement will have been satisfied.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in Large Cap Fund's final Prospectus/Proxy Statement relating to
the Shares included in the Registration Statement.

THIS PROXY IS BEING SOLICITED ON BEHALF OF THE BOARD OF DIRECTORS OF SIT LARGE
CAP GROWTH FUND, INC.

         The undersigned hereby appoints Eugene C. Sit and Paul E. Rasmussen,
and each of them, with power to act without the other and with the right of
substitution in each, as proxies of the undersigned and hereby authorizes each
of them to represent and to vote, as designated below, all the shares of Sit
Regional Growth Fund (the "Regional Fund"), a series of Sit Mutual Funds, Inc.,
held of record by the undersigned on ,2000 at the Special Meeting of
shareholders of the Acquired Fund to be held on , 2000, or any adjournments or
postponements thereof, with all powers the undersigned would possess if present
in person. All previous proxies given with respect to the Special Meeting hereby
are revoked.

THE PROXIES ARE INSTRUCTED TO VOTE AS FOLLOWS:

1.       PROPOSAL TO APPROVE AN AGREEMENT AND PLAN OF REORGANIZATION (the
         "Plan") providing for (a) the acquisition of substantially all of the
         assets and the assumption of all liabilities of Regional Fund by Sit
         Large Cap Growth Fund, Inc. ("Large Cap Fund") in exchange for shares
         of common stock of Large Cap Fund having an aggregate net asset value
         equal to the aggregate value of the assets acquired (less the
         liabilities assumed) of Regional Fund and (b) the liquidation of
         Regional Fund and the pro rata distribution of Large Cap Fund shares to
         Regional Fund shareholders. Under the Plan, each Regional Fund
         shareholder will receive Large Cap Fund shares with a net asset value
         equal as of the effective time of the Plan to the net asset value of
         their Regional Fund shares. A vote in favor of the Plan will be
