--------------------------------------------------------------------------------

These proposals will be considered by shareholders who owned shares of the
Selling Funds on Jan. 15, 2010, at a joint special meeting of such shareholders
(the "Meeting") that will be held at [10:00 a.m. CDT] on [meeting date], at [The
Marquette Hotel, 710 Marquette Avenue, Minneapolis, Minnesota 55402 in the
Minnesota River Room on the Third Floor]. Each of the Selling Funds and the
Buying Funds (collectively, the "Funds") is a registered open-end management
investment company (or a series thereof) and is part of the RiverSource Family
of Funds, which includes funds branded "RiverSource" and "Seligman." Please read
this combined proxy statement/prospectus and keep it for future reference.

Although the Board of Directors (the "Board" or the "Board of Directors") of
each Selling Fund recommends that shareholders approve the reorganization (each
a "Reorganization") of each Selling Fund with the corresponding Buying Fund, the
Reorganization of each Selling Fund is not conditioned upon the Reorganization
of any other Selling Fund. Accordingly, if shareholders of one Selling Fund
approve its Reorganization, but shareholders of another Selling Fund do not
approve that Selling Fund's Reorganization, it is expected that the
Reorganization of the first Selling Fund will take place as described in this
proxy statement/prospectus.

HOW EACH REORGANIZATION WILL WORK

-  Each Selling Fund will transfer all of its assets to the corresponding Buying
   Fund in exchange for shares of such Buying Fund ("Reorganization Shares") and
   the assumption by the Buying Fund of all of the Selling Fund's liabilities.

-  Each Buying Fund will issue Reorganization Shares with an aggregate net asset
   value equal to the aggregate value of the assets that it receives from the
   corresponding Selling Fund, less the liabilities it assumes from the
   corresponding Selling Fund. The Reorganization Shares of each class will be
   distributed to the Selling Fund's shareholders of the corresponding class in
   proportion to their holdings in such class of the Selling Fund. For example,
   holders of Class A shares of a Selling Fund will receive Class A shares of
   the corresponding Buying Fund with the same aggregate net asset value as
   their Selling Fund Class A shares at the time of the Reorganization. You will
   not pay any sales charge in connection with this distribution of
   Reorganization Shares. If you already have a Buying Fund account with the
   exact registration as the Selling Fund account, shares distributed in the
   Reorganization are typically added to that account. As a result, when average
   cost is calculated for federal income tax purposes, the cost of the shares in
   the two accounts you owned will be combined.

SECTION A -- REORGANIZATION PROPOSALS

The following information describes each proposed Reorganization.

SUMMARY

This combined proxy statement/prospectus is being used by each Selling Fund to
solicit proxies to vote at a joint special meeting of shareholders. Shareholders
of each Selling Fund will consider a proposal to approve the Agreement and Plan
of Reorganization (the "Agreement") providing for the Reorganization of their
Selling Fund into the corresponding Buying Fund. The form of the Agreement is
included as Exhibit A.

The following is a summary. More complete information appears later in this
proxy statement/prospectus. You should read the entire proxy
statement/prospectus and the exhibits because they contain details that are not
included in this summary.

HOW EACH REORGANIZATION WILL WORK

-  Each Selling Fund will transfer all of its assets to the corresponding Buying
   Fund in exchange for shares of the corresponding Buying Fund ("Reorganization
   Shares") and the assumption by the corresponding Buying Fund of all of the
   Selling Fund's liabilities.

-  Each Buying Fund will issue Reorganization Shares with an aggregate net asset
   value equal to the aggregate value of the assets that it receives from the
   corresponding Selling Fund, less the liabilities it assumes from the
   corresponding Selling Fund. Reorganization Shares of each class of each
   Buying Fund will be distributed to the shareholders of the corresponding
   class of the corresponding Selling Fund in proportion to their holdings of
   such class of such Selling Fund. For example, holders of Class A shares of a
   Selling Fund will receive Class A shares of the corresponding Buying Fund
   with the same aggregate net asset value as the aggregate net asset value of
   their Selling Fund Class A shares at the time of the Reorganization. If you
   already have a Buying Fund account with the exact registration as the Selling
   Fund account, shares distributed in the Reorganization are typically added to
   that account. As a result, when average cost is calculated for federal income
   tax purposes, the cost of the shares in the two accounts you owned will be
   combined.

-  As part of the Reorganization of your Selling Fund, systematic transactions
   (such as bank authorizations and systematic payouts) currently set up for
   your Selling Fund account may be transferred to your new Buying Fund account.
   Please contact your financial intermediary for additional details.

-  Neither the Selling Fund nor the shareholders of any Selling Fund will pay
   any sales charge in connection with acquiring Reorganization shares.

-  After a Reorganization is completed, Selling Fund shareholders will be
   shareholders of the corresponding Buying Fund, and the Selling Fund will be
   dissolved.

TAX CONSEQUENCES

Each Reorganization is expected to be tax-free for federal income tax purposes
and will not take place unless the Selling Fund and the corresponding Buying
Fund receive a satisfactory opinion of tax counsel substantially to the effect
that it will be tax-free, as described in more detail in the section entitled
"Tax Status of the Reorganizations." Accordingly, no gain or loss is expected to
be recognized by the Selling Fund or its shareholders as a direct result of a
Reorganization. Some or all of the portfolio assets of a Selling Fund may be
sold in connection with its Reorganization. The actual tax impact of such sales
will depend on the difference between the price at which such portfolio assets
are sold and the Selling Fund's tax basis in such assets. Any net capital gains
recognized in these sales will be distributed to shareholders as capital gain
dividends (to the extent of net realized long-term capital gains over net
realized short-term capital losses) and/or ordinary dividends (to the extent of
net realized short-term capital gains over net realized long-term capital
losses) during or with respect to the year of sale, and such distributions will
be taxable to shareholders. Additionally, because each Reorganization will end
the tax year of the applicable Selling Fund, it will accelerate distributions to
shareholders from the Selling Fund for its short tax year ending on the date of
the Reorganization. Those tax year-end distributions will be taxable except to
the extent of any exempt-interest dividends, and will include any capital gains
resulting from portfolio turnover prior to the Reorganization that were not
previously distributed. At any time prior to a Reorganization, a shareholder may
redeem shares of a Selling Fund. This would likely result in the recognition of
gain or loss by the shareholder for federal income tax purposes. If a
shareholder holds Selling Fund shares in a non-taxable account, distributions
and redemption proceeds with respect to those shares will not be taxable to the
shareholder if those amounts remain in the non-taxable account. Further,
shareholders of RiverSource Tax-Exempt Money Market Fund, which distributes tax-
exempt dividends, can expect to receive taxable distributions, and not tax-
exempt income, following the Fund's merger into RiverSource Government Money
Market Fund.

The tax basis and holding period of the shareholders' Selling Fund shares are
expected to carry over to the shareholders' Reorganization Shares in the Buying
Fund.

For more information about the federal income tax consequences of the
Reorganizations, see the section entitled "Tax Status of the Reorganizations."

FEES AND EXPENSES OF THE FUND

PROPOSAL 1. REORGANIZATION OF RIVERSOURCE PARTNERS AGGRESSIVE GROWTH FUND INTO
RIVERSOURCE MID CAP GROWTH FUND

The following tables describe the fees and expenses that you may pay if you buy
and hold shares of the Selling Fund or shares of the Buying Fund. The tables
also show pro forma fees and expenses of the Buying Fund assuming the proposed
Reorganization relating to the Buying Fund had been in effect at the beginning
of the most recent fiscal year. You may qualify for sales charge discounts on
Class A shares of a Fund if you and members of your household invest, or agree
to invest in the future, at least $50,000 in the RiverSource Family of Funds.
More information about these and other discounts is available from your
financial professional and under "Sales Charges" in Exhibit C of this proxy
statement/prospectus and under "Class A -- Calculation of the Sales Charge" in
the Fund's Statement of Additional Information (SAI).

Annual fund operating expenses are based on expenses incurred during the Fund's
most recently completed fiscal year, and are expressed as a percentage (expense
ratio) of the Fund's average net assets during the period. The tables have been
adjusted to reflect current fee schedules but have not been adjusted to reflect
the Fund's assets as of a different period or point in time, as asset levels
will fluctuate. As of the date of this proxy statement/prospectus, a Fund's net
assets may be lower or higher than the Fund's average net assets during the most
recently completed fiscal year. In general, a fund's annual operating expenses
will increase as the fund's assets decrease. Accordingly, the Fund's annual
operating expenses, if adjusted based on assets as of the date of this proxy
statement/prospectus, could be higher or lower than are expressed in the fee and
expense table below. The commitment by RiverSource Investments, LLC
("RiverSource Investments", "investment manager" or "manager") and its
affiliates to waive fees and/or cap (reimburse) expenses limits the impact that
any decrease in the Fund's assets will have on its total annual (net) operating
expenses in the current fiscal year.

The fees and expenses below exclude the costs of this Reorganization, because
these will be paid for by the investment manager and its affiliates.

(a) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.05% for the most recent fiscal year. The index
    against which RiverSource Partners Aggressive Growth Fund's performance is
    measured for purposes of determining the performance incentive adjustment is
    the Lipper Mid-Cap Growth Funds Index.
(b) Other expenses include an administrative services fee, a transfer agency fee
    (for all classes except Class I), a custody fee, other nonadvisory expenses,
    and a plan administration services fee (for Class R2, Class R3 and Class
    R4). Other expenses may also include fees and expenses of affiliated and
    unaffiliated funds (acquired funds) which the Fund indirectly bears when it
    invests in the acquired funds. The impact of these acquired funds' fees and
    expenses for the most recent fiscal period was less than 0.01%. Because
    acquired funds will have varied expense and fee levels and the Fund may own
    different proportions of acquired funds at different times, the amount of
    fees and expenses incurred by the Fund with respect to such investments will
    vary.
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until July 31, 2010, unless
    sooner terminated at the discretion of RiverSource Partners Aggressive
    Growth Fund's Board. Any amounts waived will not be reimbursed by the Fund.
    Under this agreement, net fund expenses (excluding fees and expenses of
    acquired funds), before giving effect to any performance incentive
    adjustment, will not exceed 1.28% for Class A, 2.06% for Class B, 2.04% for
    Class C, 0.83% for Class I, 1.63% for Class R2, 1.38% for Class R3,1.13% for
    Class R4 and 0.88% for Class R5.
(d) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.12% for the most recent fiscal year. The index
    against which RiverSource Mid Cap Growth Fund's performance is measured for
    purposes of determining the performance incentive adjustment is the Lipper
    Mid-Cap Growth Funds Index.
(e) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until Nov. 30, 2009, unless
    sooner terminated at the discretion of RiverSource Mid Cap Growth Fund's
    Board. Any amounts waived will not be reimbursed by the Fund. Under this
    agreement, net fund expenses (excluding fees and expenses of acquired
    funds), before giving effect to any performance incentive adjustment, will
    not exceed 1.07% for Class R4.
(f) Pending approval by shareholders of the proposed Reorganization, the
    investment manager and its affiliates have agreed to waive certain fees and
    expenses for one year following the effective date of the merger based on
    the least of (i) the Buying Fund's expense ratio (before giving effect to
    any performance incentive adjustment) as of its fiscal year-end on November
    30, 2009; (ii) the Buying Fund's expense cap based on application of the
    Buying Fund's Board's pricing philosophy, including the assets of both the
    Buying Fund and the Selling Fund (see "Reasons for the Proposed
    Reorganizations and Board Deliberations" for more information); or (iii) the
    Selling Fund's current expense cap commitment pursuant to which net fund
    expenses (excluding fees and expenses of acquired funds) before giving
    effect to any performance incentive adjustment, will not exceed 1.28% for
    Class A, 2.06% for Class B, 2.04% for Class C, 0.83% for Class I, 1.63% for
    Class R2, 1.38% for Class R3, 1.13% for Class R4 and 0.88% for Class R5.
 *  The performance incentive adjustment agreements for the Selling Fund and the
    Buying Fund are structured identically and are computed by comparing the
    Fund's performance to the performance of an index of comparable funds
    published by Lipper Inc., as noted above. In certain circumstances, the
    Fund's Board may approve a change in the index. The maximum adjustment
    (increase or decrease) is 0.12% of the average net assets on an annual
    basis. The adjustment is determined monthly by measuring the percentage
    differences over a rolling 12-month period between the performance of the
    Fund and the change in the designated Lipper index. Additional information
    on the calculation methodology is set forth in the Merger SAI.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those
periods, both under the current arrangements and, for the Buying Fund, assuming
the proposed Reorganization had been in effect. These examples also assume that
your investment has a 5% return each year and that the Fund's operating expenses
remain the same, except for any contractual fee waiver/expense reimbursement
that is reflected in these examples for only the first year. Although your
actual costs may be higher or lower, based on these assumptions your costs would
be:

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when
it buys and sells securities (or "turns over" its portfolio). A higher portfolio
turnover rate may indicate higher transaction costs and may result in higher
taxes when Fund shares are held in a taxable account. These costs, which are not
reflected in annual fund operating expenses or in the example, affect the Fund's
performance. During the most recent fiscal year, the Fund's portfolio turnover
rate was the following percentage of the average value of the Fund's portfolio:

PROPOSAL 2. REORGANIZATION OF RIVERSOURCE PARTNERS SELECT VALUE FUND INTO
RIVERSOURCE MID CAP
VALUE FUND

The following tables describe the fees and expenses that you may pay if you buy
and hold shares of the Selling Fund or shares of the Buying Fund. The tables
also show pro forma fees and expenses of the Buying Fund assuming the proposed
Reorganization relating to the Buying Fund had been in effect at the beginning
of the most recent fiscal year. You may qualify for sales charge discounts on
Class A shares of a Fund if you and members of your household invest, or agree
to invest in the future, at least $50,000 in the RiverSource Family of Funds.
More information about these and other discounts is available from your
financial professional and under "Sales Charges" in Exhibit C of this proxy
statement/prospectus and under "Class A -- Calculation of the Sales Charge" in
the Fund's Statement of Additional Information (SAI).

Annual fund operating expenses are based on expenses incurred during the Fund's
most recently completed fiscal year, and are expressed as a percentage (expense
ratio) of the Fund's average net assets during the period. The tables have been
adjusted to reflect current fee schedules but have not been adjusted to reflect
the Fund's assets as of a different period or point in time, as asset levels
will fluctuate. As of the date of this proxy statement/prospectus, a Fund's net
assets may be lower or higher than the Fund's average net assets during the most
recently completed fiscal year. In general, a fund's annual operating expenses
will increase as the fund's assets decrease. Accordingly, the Fund's annual
operating expenses, if adjusted based on assets as of the date of this proxy
statement/prospectus, could be higher or lower than are expressed in the fee and
expense table below. The commitment by the investment manager and its affiliates
to waive fees and/or cap (reimburse) expenses limits the impact that any
decrease in the Fund's assets will have on its total annual (net) operating
expenses in the current fiscal year.

The fees and expenses below exclude the costs of this Reorganization, because
these will be paid for by the investment manager and its affiliates.

(a) Includes the impact of a performance incentive adjustment fee that increased
    the management fee by 0.10% for the most recent fiscal year. The index
    against which RiverSource Partners Select Value Fund's performance is
    measured for purposes of determining the performance incentive adjustment is
    the Lipper Mid-Cap Value Funds Index.
(b) Other expenses include an administrative services fee, a transfer agency fee
    (for all classes except Class I), a custody fee, other nonadvisory expenses,
    and a plan administration services fee (for Class R4). Other expenses may
    also include fees and expenses of affiliated and unaffiliated funds
    (acquired funds) which the Fund indirectly bears when it invests in the
    acquired funds. The impact of these acquired funds' fees and expenses for
    the most recent fiscal period was less than 0.01%. Because acquired funds
    will have varied expense and fee levels and the Fund may own different
    proportions of acquired funds at different times, the amount of fees and
    expenses incurred by the Fund with respect to such investments will vary.
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until July 31, 2010, unless
    sooner terminated at the discretion of RiverSource Partners Select Value
    Fund's Board. Any amounts waived will not be reimbursed by the Fund. Under
    this agreement, net fund expenses (excluding fees and expenses of acquired
    funds), before giving effect to any performance incentive adjustment, will
    not exceed 1.28% for Class A, 2.05% for Class B, 2.04% for Class C, 0.83%
    for Class I and 1.13% for Class R4.
(d) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.12% for the most recent fiscal year. The index
    against which RiverSource Mid Cap Value Fund's performance is measured for
    purposes of determining the performance incentive adjustment is the Lipper
    Mid-Cap Value Funds Index.
(e) Pending approval by shareholders of the proposed Reorganization, the
    investment manager and its affiliates have agreed to waive certain fees and
    expenses for one year following the effective date of the merger based on
    the least of (i) the Buying Fund's expense ratio (before giving effect to
    any performance incentive adjustment) as of its fiscal year-end on September
    30, 2009 which was 1.31% for Class A, 2.08% for Class B, 2.07% for Class C,
    0.79% for Class I, and 1.09% for Class R4; or (ii) the Buying Fund's expense
    cap based on application of the Buying Fund's Board's pricing philosophy,
    including the assets of both the Buying Fund and the Selling Fund. See
    "Reasons for the Proposed Reorganizations and Board Deliberations" for more
    information.
 *  The performance incentive adjustment agreements for the Selling Fund and the
    Buying Fund are structured identically and are computed by comparing the
    Fund's performance to the performance of an index of comparable funds
    published by Lipper Inc., as noted above. In certain circumstances, the
    Fund's Board may approve a change in the index. The maximum adjustment
    (increase or decrease) is 0.12% of the average net assets on an annual
    basis. The adjustment is determined monthly by measuring the percentage
    differences over a rolling 12-month period between the performance of the
    Fund and the change in the designated Lipper index. Additional information
    on the calculation methodology is set forth in the Merger SAI.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those
periods, both under the current arrangements and, for the Buying Fund, assuming
the proposed Reorganization had been in effect. These examples also assume that
your investment has a 5% return each year and that the Fund's operating expenses
remain the same, except for any contractual fee waiver/expense reimbursement
that is reflected in these examples for only the first year. Although your
actual costs may be higher or lower, based on these assumptions your costs would
be:

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when
it buys and sells securities (or "turns over" its portfolio). A higher portfolio
turnover rate may indicate higher transaction costs and may result in higher
taxes when Fund shares are held in a taxable account. These costs, which are not
reflected in annual fund operating expenses or in the example, affect the Fund's
performance. During the most recent fiscal year, the Fund's portfolio turnover
rate was the following percentage of the average value of the Fund's portfolio:

PROPOSAL 3. REORGANIZATION OF RIVERSOURCE PARTNERS SMALL CAP EQUITY FUND INTO
SELIGMAN SMALLER-CAP VALUE FUND

The following tables describe the fees and expenses that you may pay if you buy
and hold shares of the Selling Fund or shares of the Buying Fund. The tables
also show pro forma fees and expenses of the Buying Fund assuming the proposed
Reorganization relating to the Buying Fund had been in effect at the beginning
of the most recent fiscal year. You may qualify for sales charge discounts on
Class A shares of a Fund if you and members of your household invest, or agree
to invest in the future, at least $50,000 in the RiverSource Family of Funds.
More information about these and other discounts is available from your
financial professional and under "Sales Charges" in Exhibit C of this proxy
statement/prospectus and under "Class A -- Calculation of the Sales Charge" in
the Fund's Statement of Additional Information (SAI).

Annual fund operating expenses are based on expenses incurred during the Fund's
most recently completed fiscal year, and are expressed as a percentage (expense
ratio) of the Fund's average net assets during the period. The tables have been
adjusted to reflect current fee schedules but have not been adjusted to reflect
the Fund's assets as of a different period or point in time, as asset levels
will fluctuate. As of the date of this proxy statement/prospectus, a Fund's net
assets may be lower or higher than the Fund's average net assets during the most
recently completed fiscal year. In general, a fund's annual operating expenses
will increase as the fund's assets decrease. Accordingly, the Fund's annual
operating expenses, if adjusted based on assets as of the date of this proxy
statement/prospectus, could be higher or lower than are expressed in the fee and
expense table below. The commitment by the investment manager and its affiliates
to waive fees and/or cap (reimburse) expenses limits the impact that any
decrease in the Fund's assets will have on its total annual (net) operating
expenses in the current fiscal year.

The fees and expenses below exclude the costs of this Reorganization, because
these will be paid for by the investment manager and its affiliates.

(a) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.05% for the most recent fiscal year. The index
    against which RiverSource Partners Small Cap Equity Fund's performance is
    measured for purposes of determining the performance incentive adjustment is
    the Lipper Small-Cap Core Funds Index. In certain circumstances, the Fund's
    Board may approve a change in the index. The maximum adjustment (increase or
    decrease) is 0.12% of the average net assets on an annual basis. The
    adjustment is determined monthly by measuring the percentage difference over
    a rolling 12-month period between the performance of the Fund and the change
    in the designated Lipper index. Additional information on the calculation
    methodology is set forth in the Fund's Merger SAI.
(b) Other expenses include an administrative services fee, a transfer agency fee
    (for all classes except Class I), a custody fee, other non-advisory expenses
    and a plan administration services fee (for Class R4).
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until July 31, 2010, unless
    sooner terminated at the discretion of RiverSource Partners Small Cap Equity
    Fund's Board. Any amounts waived will not be reimbursed by the Fund. Under
    this agreement, net fund expenses (excluding fees and expenses of acquired
    funds), before giving effect to any performance incentive adjustment, will
    not exceed 1.33% for Class A, 2.10% for Class B, 2.09% for Class C, 0.88%
    for Class I and 1.18% for Class R4.
(d) In addition to the Fund's total annual operating expenses that the Fund
    bears directly, the Fund's shareholders indirectly bear the expenses of the
    acquired funds (affiliated and unaffiliated funds) in which the Fund
    invests. The Fund's "Acquired fund fees and expenses," based on its
    investment in the acquired funds, is as shown.
(e) Other expenses include an administrative services fee, a transfer agency fee
    (for all classes except Class I), a custody fee, other nonadvisory expenses,
    and a plan administration services fee (for Class R4). Other expenses may
    also include fees and expenses of affiliated and unaffiliated funds
    (acquired funds) which the Fund indirectly bears when it invests in the
    acquired funds. The impact of these acquired funds' fees and expenses for
    the most recent fiscal period was less than 0.01%. Because acquired funds
    will have varied expense and fee levels and the Fund may own different
    proportions of acquired funds at different times, the amount of fees and
    expenses incurred by the Fund with respect to such investments will vary.
(f) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until Sept. 11, 2010, unless
    sooner terminated at the discretion of Seligman Smaller-Cap Value Fund's
    Board. Any amounts waived will not be reimbursed by the Fund. Under this
    agreement, net fund expenses (excluding fees and expenses of acquired funds)
    will not exceed 1.33% for Class A, 2.10% for Class B, 2.09% for Class C,
    0.88% for Class I and 1.18% for Class R4. Pending approval by shareholders
    of the proposed Reorganization, this agreement will be replaced by the
    agreement discussed in footnote (g) below.
(g) Pending approval by shareholders of the proposed Reorganization, the
    investment manager and its affiliates have agreed to waive certain fees and
    expenses for one year following the effective date of the merger based on
    the least of (i) the Buying Fund's expense ratio (before giving effect to
    any performance incentive adjustment) as of its fiscal year-end on December
    31, 2009; (ii) the Buying Fund's expense cap based on application of the
    Buying Fund's Board's pricing philosophy, including the assets of both the
    Buying Fund and the Selling Fund (see "Reasons for the Proposed
    Reorganizations and Board Deliberations" for more information); or (iii) the
    Selling Fund's current expense cap commitment pursuant to which net fund
    expenses (excluding fees and expenses of acquired funds) before giving
    effect to any performance incentive adjustment, will not exceed 1.33% for
    Class A, 2.10% for Class B, 2.09% for Class C, 0.88% for Class I, and 1.18%
    for Class R4.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those
periods, both under the current arrangements and, for the Buying Fund, assuming
the proposed Reorganization had been in effect. These examples also assume that
your investment has a 5% return each year and that the Fund's operating expenses
remain the same, except for any contractual fee waiver/expense reimbursement
that is reflected in these examples for only the first year. Although your
actual costs may be higher or lower, based on these assumptions your costs would
be:

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when
it buys and sells securities (or "turns over" its portfolio). A higher portfolio
turnover rate may indicate higher transaction costs and may result in higher
taxes when Fund shares are held in a taxable account. These costs, which are not
reflected in annual fund operating expenses or in the example, affect the Fund's
performance. During the most recent fiscal year, the Fund's portfolio turnover
rate was the following percentage of the average value of the Fund's portfolio:

PROPOSAL 4. REORGANIZATION OF RIVERSOURCE PARTNERS SMALL CAP GROWTH FUND INTO
SELIGMAN FRONTIER FUND

The following tables describe the fees and expenses that you may pay if you buy
and hold shares of the Selling Fund or shares of the Buying Fund. The tables
also show pro forma fees and expenses of the Buying Fund assuming the proposed
Reorganization relating to the Buying Fund had been in effect at the beginning
of the most recent fiscal year. You may qualify for sales charge discounts on
Class A shares of a Fund if you and members of your household invest, or agree
to invest in the future, at least $50,000 in the RiverSource Family of Funds.
More information about these and other discounts is available from your
financial professional and under "Sales Charges" in Exhibit C of this proxy
statement/prospectus and under "Class A -- Calculation of the Sales Charge" in
the Fund's Statement of Additional Information (SAI).

Annual fund operating expenses are based on expenses incurred during the Fund's
most recently completed fiscal year, and are expressed as a percentage (expense
ratio) of the Fund's average net assets during the period. The tables have been
adjusted to reflect current fee schedules but have not been adjusted to reflect
the Fund's assets as of a different period or point in time, as asset levels
will fluctuate. As of the date of this proxy statement/prospectus, a Fund's net
assets may be lower or higher than the Fund's average net assets during the most
recently completed fiscal year. In general, a fund's annual operating expenses
will increase as the fund's assets decrease. Accordingly, the Fund's annual
operating expenses, if adjusted based on assets as of the date of this proxy
statement/prospectus, could be higher or lower than are expressed in the fee and
expense table below. The commitment by the investment manager and its affiliates
to waive fees and/or cap (reimburse) expenses limits the impact that any
decrease in the Fund's assets will have on its total annual (net) operating
expenses in the current fiscal year.

The fees and expenses below exclude the costs of this Reorganization, because
these will be paid for by the investment manager and its affiliates.

(a) Includes the impact of a performance incentive adjustment fee that increased
    the management fee by 0.02% for the most recent fiscal year. The index
    against which RiverSource Partners Small Cap Growth Fund's performance is
    measured for purposes of determining the performance incentive adjustment is
    the Lipper Small-Cap Growth Funds Index. In certain circumstances, the
    Fund's Board may approve a change in the index. The maximum adjustment
    (increase or decrease) is 0.12% of the average net assets on an annual
    basis. The adjustment is determined monthly by measuring the percentage
    difference over a rolling 12-month period between the performance of the
    Fund and the change in the designated Lipper index. Additional information
    on the calculation methodology is set forth in the Fund's Merger SAI.
(b) Other expenses include an administrative services fee, a transfer agency fee
    (for all classes except Class I), a custody fee, other nonadvisory expenses,
    and a plan administration services fee (for Class R2, Class R3 and Class
    R4). Other expenses may also include fees and expenses of affiliated and
    unaffiliated funds (acquired funds) which the Fund indirectly bears when it
    invests in the acquired funds. The impact of these acquired funds' fees and
    expenses for the most recent fiscal period was less than 0.01%. Because
    acquired funds will have varied expense and fee levels and the Fund may own
    different proportions of acquired funds at different times, the amount of
    fees and expenses incurred by the Fund with respect to such investments will
    vary.
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until May 31, 2010, unless
    sooner terminated at the discretion of RiverSource Partners Small Cap Growth
    Fund's Board. Any amounts waived will not be reimbursed by the Fund. Under
    this agreement, net fund expenses (excluding fees and expenses of acquired
    funds), before giving effect to any performance incentive adjustment, will
    not exceed 1.51% for Class A, 2.29% for Class B, 2.28% for Class C, 1.06%
    for Class I, 1.86% for Class R2, 1.61% for Class R3, 1.36% for Class R4 and
    1.11% for Class R5.
(d) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until Dec. 31, 2010, unless
    sooner terminated at the discretion of Seligman Frontier Fund's Board. Any
    amounts waived will not be reimbursed by the Fund. Under this agreement, net
    fund expenses (excluding fees and expenses of acquired funds) will not
    exceed 1.51% for Class A, 2.29% for Class B, 2.28% for Class C, 1.06% for
    Class I, 1.86% for Class R2, 1.61% for Class R3, 1.36% for Class R4 and
    1.11% for Class R5.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those
periods, both under the current arrangements and, for the Buying Fund, assuming
the proposed Reorganization had been in effect. These examples also assume that
your investment has a 5% return each year and that the Fund's operating expenses
remain the same, except for any contractual fee waiver/expense reimbursement
that is reflected in these examples for only the first year. Although your
actual costs may be higher or lower, based on these assumptions your costs would
be:

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when
it buys and sells securities (or "turns over" its portfolio). A higher portfolio
turnover rate may indicate higher transaction costs and may result in higher
taxes when Fund shares are held in a taxable account. These costs, which are not
reflected in annual fund operating expenses or in the example, affect the Fund's
performance. During the most recent fiscal year, the Fund's portfolio turnover
rate was the following percentage of the average value of the Fund's portfolio:

PROPOSAL 5. REORGANIZATION OF SELIGMAN GLOBAL SMALLER COMPANIES FUND INTO
RIVERSOURCE PARTNERS INTERNATIONAL SMALL CAP FUND

The following tables describe the fees and expenses that you may pay if you buy
and hold shares of the Selling Fund or shares of the Buying Fund. The tables
also show pro forma fees and expenses of the Buying Fund assuming the proposed
Reorganization relating to the Buying Fund had been in effect at the beginning
of the most recent fiscal year. You may qualify for sales charge discounts on
Class A shares of a Fund if you and members of your household invest, or agree
to invest in the future, at least $50,000 in the RiverSource Family of Funds.
More information about these and other discounts is available from your
financial professional and under "Sales Charges" in Exhibit C of this proxy
statement/prospectus and under "Class A -- Calculation of the Sales Charge" in
the Fund's Statement of Additional Information (SAI).

Annual fund operating expenses are based on expenses incurred during the Fund's
most recently completed fiscal year, and are expressed as a percentage (expense
ratio) of the Fund's average net assets during the period. The tables have been
adjusted to reflect current fee schedules but have not been adjusted to reflect
the Fund's assets as of a different period or point in time, as asset levels
will fluctuate. As of the date of this proxy statement/prospectus, a Fund's net
assets may be lower or higher than the Fund's average net assets during the most
recently completed fiscal year. In general, a fund's annual operating expenses
will increase as the fund's assets decrease. Accordingly, the Fund's annual
operating expenses, if adjusted based on assets as of the date of this proxy
statement/prospectus, could be higher or lower than are expressed in the fee and
expense table below. The commitment by the investment manager and its affiliates
to waive fees and/or cap (reimburse) expenses limits the impact that any
decrease in the Fund's assets will have on its total annual (net) operating
expenses in the current fiscal year.

The fees and expenses below exclude the costs of this Reorganization, because
these will be paid for by the investment manager and its affiliates.

(a) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee, other nonadvisory expenses, and a plan administration
    services fee (for Class R2). Other expenses may also include fees and
    expenses of affiliated and unaffiliated funds (acquired funds) which the
    Fund indirectly bears when it invests in the acquired funds. The impact of
    these acquired funds' fees and expenses for the most recent fiscal period
    was less than 0.01%. Because acquired funds will have varied expense and fee
    levels and the Fund may own different proportions of acquired funds at
    different times, the amount of fees and expenses incurred by the Fund with
    respect to such investments will vary.
(b) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.05% for the most recent fiscal year. The index
    against which RiverSource Partners International Small Cap Fund's
    performance is measured for purposes of determining the performance
    incentive adjustment is the Lipper International Small-Cap Funds Index. In
    certain circumstances, the Fund's Board may approve a change in the index.
    The maximum adjustment (increase or decrease) is 0.12% of the average net
    assets on an annual basis. The adjustment is determined monthly by measuring
    the percentage difference over a rolling 12-month period between the
    performance of the Fund and the change in the designated Lipper index.
    Additional information on the calculation methodology is set forth in the
    Fund's Merger SAI.
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until Oct. 31, 2009, unless
    sooner terminated at the discretion of RiverSource Partners International
    Small Cap Fund's Board. Any amounts waived will not be reimbursed by the
    Fund. Under this agreement, net fund expenses (excluding fees and expenses
    of acquired funds), before giving effect to any performance incentive
    adjustment, will not exceed 1.76% for Class A, 2.53% for Class B, 2.52% for
    Class C, 2.11% for Class R2 and 1.36% for Class R5.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those
periods, both under the current arrangements and, for the Buying Fund, assuming
the proposed Reorganization had been in effect. These examples also assume that
your investment has a 5% return each year and that the Fund's operating expenses
remain the same, except for any contractual fee waiver/expense reimbursement
that is reflected in these examples for only the first year. Although your
actual costs may be higher or lower, based on these assumptions your costs would
be:

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when
it buys and sells securities (or "turns over" its portfolio). A higher portfolio
turnover rate may indicate higher transaction costs and may result in higher
taxes when Fund shares are held in a taxable account. These costs, which are not
reflected in annual fund operating expenses or in the example, affect the Fund's
performance. During the most recent fiscal year, the Fund's portfolio turnover
rate was the following percentage of the average value of the Fund's portfolio:

PROPOSAL 6. REORGANIZATION OF RIVERSOURCE TAX-EXEMPT MONEY MARKET FUND INTO
RIVERSOURCE GOVERNMENT MONEY MARKET FUND

The following tables describe the fees and expenses that you may pay if you buy
and hold shares of the Selling Fund or shares of the Buying Fund. The tables
also show pro forma fees and expenses of the Buying Fund assuming the proposed
Reorganization relating to the Buying Fund had been in effect at the beginning
of the most recent fiscal year. For purposes of comparison, the single class of
shares of RiverSource Tax-Exempt Money Market Fund is referred to as Class A
shares.

Annual fund operating expenses are based on expenses incurred during the Fund's
most recently completed fiscal year, and are expressed as a percentage (expense
ratio) of the Fund's average net assets during the period. The tables have been
adjusted to reflect current fee schedules but have not been adjusted to reflect
the Fund's assets as of a different period or point in time, as asset levels
will fluctuate. As of the date of this proxy statement/prospectus, a Fund's net
assets may be lower or higher than the Fund's average net assets during the most
recently completed fiscal year. In general, a fund's annual operating expenses
will increase as the fund's assets decrease. Accordingly, the Fund's annual
operating expenses, if adjusted based on assets as of the date of this proxy
statement/prospectus, could be higher or lower than are expressed in the fee and
expense table below. The commitment by the investment manager and its affiliates
to waive fees and/or cap (reimburse) expenses limits the impact that any
decrease in the Fund's assets will have on its total annual (net) operating
expenses in the current fiscal year.

The fees and expenses below exclude the costs of this Reorganization, because
these will be paid for by the investment manager and its affiliates.

(a) The distributor has currently agreed not to be reimbursed by RiverSource
    Government Money Market Fund for distribution (12b-1) fees equal to 0.15% of
    the stated amount for Class A. This waiver is reflected under "Fee
    waiver/expense reimbursement" in the table. Any amount of the distribution
    (12b-1) fees not paid as reimbursement to or collected by the distributor
    will not be paid or reimbursed by RiverSource Government Money Market Fund.
(b) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee and other nonadvisory expenses.
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until April 30, 2010, unless
    sooner terminated at the discretion of RiverSource Government Money Market
    Fund's Board. Any amounts waived will not be reimbursed by the Fund. Under
    this agreement, net fund expenses will not exceed 0.66% for Class A.

From time to time, the investment manager and its affiliates may waive or absorb
expenses of the Fund for the purpose of allowing the Fund to avoid a negative
net yield or to increase the Fund's positive net yield. The Fund's yield would
be negative if Fund expenses exceed Fund income. Any such expense limitation is
voluntary and may be revised or terminated at any time without notice.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those
periods, both under the current arrangements and, for the Buying Fund, assuming
the proposed Reorganization had been in effect. These examples also assume that
your investment has a 5% return each year and that the Fund's operating expenses
remain the same, except for any contractual fee waiver/expense reimbursement
that is reflected in these examples for only the first year. Although your
actual costs may be higher or lower, based on these assumptions your costs would
be:

PROPOSAL 1. REORGANIZATION OF RIVERSOURCE PARTNERS AGGRESSIVE GROWTH FUND INTO
RIVERSOURCE MID CAP GROWTH FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- Have RiverSource Investments as an investment manager.

- Have the same policies for buying and selling shares and the same exchange
  rights.

- Have the same distribution policies.

- Offer the same classes of shares: A, B, C, I, R2, R3, R4 and R5.

- Are structured as a series of capital stock of an open-end management
  investment company organized as a Minnesota corporation.

COMPARISON OF INVESTMENT OBJECTIVES

Both Funds seek growth of capital. Both Funds are intended for long-term
investors and are not intended as short-term trading vehicle. Because any
investment involves risk, there is no assurance, the Fund's objective can be
achieved. Only shareholders can change the Fund's objective.

The investment objectives for the Funds are as follows:

          SELLING FUND: RiverSource Partners Aggressive Growth Fund seeks to
                        provide shareholders with long-term capital growth.

          BUYING FUND: RiverSource Mid Cap Growth Fund seeks to provide
                       shareholders with growth of capital.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

The Selling Fund and the Buying Fund have similar principal investment
strategies. Both Funds primarily invest in equity securities of medium sized
companies whose market capitalization at the time of purchase falls within the
range of the Russell Midcap(R) Growth Index. The Buying Fund has a policy of
investing at least 80% of its net assets at the time of purchase in equity
securities of medium sized companies, while the Selling Fund does not have this
restriction. The Buying Fund will provide shareholders with at least 60 days'
notice of any change to the 80% policy. In addition to medium sized companies
both Funds may invest in companies of any size or capitalization, but the Buying
Fund limits these investments to 20% of the Fund's net assets.

Although RiverSource Investments serves as investment manager of both Funds, the
Selling Fund was, until Nov. 6, 2009, subadvised by American Century Investment
Management, Inc. (American Century) and Turner Investment Partners, Inc.
(Turner). The Selling Fund's Board of Directors terminated the subadvisory
contracts of American Century and Turner for managing the Selling Fund's
portfolio. Since Nov. 6, 2009, RiverSource Investments has solely managed the
Selling Fund.

Detailed strategies for the Selling Fund and the Buying Fund are set forth
below:

                                               economic sector and, at times, it may
                                               emphasize one or more particular sectors.

--------------------------------------------------------------------------------------------
</Table>




                                       27



In addition to the principal investment strategies set forth above, each Fund
also has the following principal investment strategies:

In pursuit of the Fund's objective, the investment manager chooses equity
investments by, among other things:

- Analyzing a company's:

  - management's track record;

  - financial strength;

  - growth potential (on average, a company's expected ability to generate
    future earnings growth of at least 15% per year); and

  - competitive market position.

- Identifying sectors with growth potential and weighting purchases in those
  sectors more heavily.

- Considering market trends and identifying opportunities within multiple
  industries that offer a desirable risk/reward trade-off for shareholders.

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- The security is overvalued relative to alternative investments.

- The company has met the investment manager's earnings and/or growth
  expectations.

- Political, economic, or other events could affect the company's performance.

- The company or the security continues to meet the other standards described
  above.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed.

For purposes of this discussion, a "fundamental" investment policy is one that
may not be changed without a shareholder vote. The Selling Fund and the Buying
Fund have identical fundamental investment policies. Neither of the Funds will:

- Act as an underwriter (sell securities for others). However, under the
  securities laws, the Fund may be deemed to be an underwriter when it purchases
  securities directly from the issuer and later resells them.

- Lend securities or participate in an interfund lending program if the total of
  all such loans would exceed 33 1/3% of the Fund's total assets except this
  fundamental investment policy shall not prohibit the Fund from purchasing
  money market securities, loans, loan participation or other debt securities,
  or from entering into repurchase agreements.

- Borrow money, except for temporary purposes (not for leveraging or investment)
  in an amount not exceeding 33 1/3% of its total assets (including the amount
  borrowed) less liabilities (other than borrowings) immediately after the
  borrowings.

- Issue senior securities, except as permitted under the 1940 Act, the rules and
  regulations thereunder and any applicable exemptive relief.

- Buy or sell real estate, unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  investing in securities or other instruments backed by real estate or
  securities of companies engaged in the real estate business or real estate
  investment trusts. For purposes of this policy, real estate includes real
  estate limited partnerships.

- Buy or sell physical commodities unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  buying or selling options and futures contracts or from investing in
  securities or other instruments backed by, or whose value is derived from,
  physical commodities.

- Purchase more than 10% of the outstanding voting securities of an issuer,
  except that up to 25% of the Fund's assets may be invested without regard to
  this 10% limitation.

- Invest more than 5% of its total assets in securities of any company,
  government, or political subdivision thereof, except the limitation will not
  apply to investments in securities issued or guaranteed by the U.S.
  government, its agencies, or instrumentalities, or other investment companies,
  and except that up to 25% of the Fund's total assets may be invested without
  regard to this 5% limitation.

- Concentrate in any one industry. According to the present interpretation by
  the SEC, this means that up to 25% of the Fund's total assets, based on
  current market value at time of purchase, can be invested in any one industry.


                                       28



COMPARISON OF NONFUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies (policies that may be changed without a
shareholder vote) of the Buying Fund. Both Funds are also subject to the
following nonfundamental policies:

- No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

- Up to 25% of the Fund's net assets may be invested in foreign investments.

COMPARISON OF PRINCIPAL RISK FACTORS

The principal investment risks associated with the Selling Fund and the Buying
Fund are substantially similar because the Funds have similar investment
objectives, principal investment strategies and investment policies. With
respect to investment policies, although the Buying Fund is required to invest
80% of its net assets in equity securities of medium-sized companies and the
Selling Fund does not have this investment requirement, which may present the
increased risk of investing in mid-sized companies for the Buying Fund,
currently both Funds have approximately the same exposure to investments in mid-
sized companies. The actual risks of investing in each Fund depend on the
securities held in each Fund's portfolio and on market conditions, both of which
change over time. The Funds are subject to the principal investment risks
described below.

ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
therefore will reflect in part the ability of the portfolio managers to select
securities and to make investment decisions that are suited to achieving the
Fund's investment objective. Due to its active management, the Fund could
underperform other mutual funds with similar investment objectives.

ISSUER RISK. An issuer may perform poorly, and therefore, the value of its
stocks and bonds may decline. Poor performance may be caused by poor management
decisions, competitive pressures, breakthroughs in technology, reliance on
suppliers, labor problems or shortages, corporate restructurings, fraudulent
disclosures or other factors.

MARKET RISK. The market value of securities may fall or fail to rise. Market
risk may affect a single issuer, sector of the economy, industry, or the market
as a whole. The market value of securities may fluctuate, sometimes rapidly and
unpredictably. This risk is generally greater for small and mid-sized companies,
which tend to be more vulnerable to adverse developments. In addition, focus on
a particular style, for example, investment in growth or value securities, may
cause the Fund to underperform other mutual funds if that style falls out of
favor with the market.

MID-SIZED COMPANY RISK. Investments in mid-sized companies often involve greater
risks than investments in larger, more established companies because mid-sized
companies may lack the management experience, financial resources, product
diversification and competitive strengths of larger companies. In addition, in
some instances the securities of mid-sized companies are traded only over-the-
counter or on regional securities exchanges and the frequency and volume of
their trading is substantially less than is typical of larger companies.

SECTOR RISK. If a fund emphasizes one or more economic sectors, it may be more
susceptible to the financial, market or economic events affecting the particular
issuers and industries in which it invests than funds that do not emphasize
particular sectors. The more a fund diversifies across sectors, the more it
spreads risk and potentially reduces the risks of loss and volatility.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- how each Fund's average annual total returns compare to recognized measures of
  market performance shown in the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4 and Class R5
shares of RiverSource Partners Aggressive Growth Fund. The second table shows
total returns from hypothetical investments in Class A, Class B, Class C, Class
I and Class R4 shares of RiverSource Mid Cap Growth Fund. Inception date for
Class R2, Class R3 and Class R5 is expected to be in the first quarter of 2010
and therefore

                                       29



performance information for these classes is not shown. These returns are
compared to the indexes shown for the same periods. For purposes of the
performance calculation in the table we assumed:

- the maximum sales charge of 5.75% for Class A shares;

- sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B and Class C;

- no sales charge for Class I, Class R2, Class R3, Class R4 and Class R5 shares;
  and

- with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

PROPOSAL 2. REORGANIZATION OF RIVERSOURCE PARTNERS SELECT VALUE FUND INTO
RIVERSOURCE MID CAP VALUE FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- Have RiverSource Investments as an investment manager.

- Have the same policies for buying and selling shares and the same exchange
  rights.

- Have the same distribution policies.

- Offer classes A, B, C, I and R4 (the Buying Fund also offers classes R2, R3,
  R5 and W).

- Are structured as a series of capital stock of an open-end management
  investment company organized as a Minnesota corporation.

COMPARISON OF INVESTMENT OBJECTIVES

Both Funds seek to provide shareholders with long-term growth of capital. Both
Funds are intended for long-term investors and are not intended as short-term
trading vehicle. Because any investment involves risk, there is no assurance,
the Fund's objective can be achieved. Only shareholders can change the Fund's
objective.

The investment objectives for the Funds are as follows:

          SELLING FUND: RiverSource Partners Select Value Fund seeks to provide
                        shareholders with long-term growth of capital.

          BUYING FUND: RiverSource Mid Cap Value Fund seeks to provide
                       shareholders with long-term growth of capital.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

The Selling Fund and the Buying Fund have similar principal investment
strategies. Both Funds invest primarily in equity securities of medium sized
companies whose market capitalization at the time of purchase falls within the
range of the Russell Midcap(R) Value Index. The Selling Fund also defines medium
sized companies as those with a market capitalization of up to $10 billion. The
Buying Fund has a policy of investing at least 80% of its net assets (including
the amount of any borrowings for investment purposes) in equity securities of
medium sized companies, while the Selling Fund does not have this requirement.
The Buying Fund will provide shareholders with at least 60 days' notice of any
change to the 80% policy. In addition to medium sized companies both Funds can
invest in companies with larger and smaller market capitalization, but the
Buying Fund limits these investments and investments in preferreds, convertibles
and other debt securities to 20% of the Fund's net assets.

Although RiverSource Investments serves as investment manager of both Funds, the
Selling Fund was, until Nov. 6, 2009, subadvised by Systematic Financial
Management, L.P. (Systematic) and WEDGE Capital Management, L.L.P. (WEDGE). The
Selling Fund's Board of Directors terminated the subadvisory contracts of
Systematic and WEDGE for managing the Selling Fund's portfolio. Since Nov. 6,
2009, RiverSource Investments has solely managed the Selling Fund.

Detailed strategies for the Selling Fund and the Buying Fund are set forth
below:

                                               any change in the 80% policy.

In addition to the principal investment strategies set forth above, each Fund
also has the following principal investment strategies:

In pursuit of the Fund's objectives, RiverSource Investments chooses equity
investments by seeking to:

- Select companies that are undervalued based on a variety of measures,
  including but not limited to price-to-earnings ratios, price-to-book ratios,
  price-to-free cash flow, current and projected dividends, sum-of-the parts or
  breakup value and historic relative price valuations.

- Identify companies with growth potential based on:

  - effective management, as demonstrated by overall performance;

  - financial strength; and

  - underappreciated potential for improvement in industry and thematic trends.

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- The security is overvalued relative to alternative investments.

- The security has reached the investment manager's price objective.

- The company has met the investment manager's earnings and/or growth
  expectations.

- The security exhibits unacceptable correlation characteristics with other
  portfolio holdings.

- The company or the security continues to meet the other standards described
  above.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. For purposes of this
discussion, a "fundamental" investment policy is one that may not be changed
without a shareholder vote. The Selling Fund and the Buying Fund have the
following identical fundamental investment policies. Neither of the Funds will:

- Act as an underwriter (sell securities for others). However, under the
  securities laws, the Fund may be deemed to be an underwriter when it purchases
  securities directly from the issuer and later resells them.

- Lend securities or participate in an interfund lending program if the total of
  all such loans would exceed 33 1/3% of the Fund's total assets except this
  fundamental investment policy shall not prohibit the Fund from purchasing
  money market securities, loans, loan participation or other debt securities,
  or from entering into repurchase agreements.

- Borrow money, except for temporary purposes (not for leveraging or investment)
  in an amount not exceeding 33 1/3% of its total assets (including the amount
  borrowed) less liabilities (other than borrowings) immediately after the
  borrowings.

- Issue senior securities, except as permitted under the 1940 Act, the rules and
  regulations thereunder and any applicable exemptive relief.

- Buy or sell real estate, unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  investing in securities or other instruments backed by real estate or
  securities of companies engaged in the real estate business or real estate
  investment trusts. For purposes of this policy, real estate includes real
  estate limited partnerships.

- Purchase more than 10% of the outstanding voting securities of an issuer,
  except that up to 25% of the Fund's assets may be invested without regard to
  this 10% limitation.

- Invest more than 5% of its total assets in securities of any company,
  government, or political subdivision thereof, except the limitation will not
  apply to investments in securities issued or guaranteed by the U.S.
  government, its agencies, or instrumentalities, or other investment companies,
  and except that up to 25% of the Fund's total assets may be invested without
  regard to this 5% limitation.

- Concentrate in any one industry. According to the present interpretation by
  the SEC, this means that up to 25% of the Fund's total assets, based on
  current market value at time of purchase, can be invested in any one industry.

In addition, although the fundamental policy related to buying and selling
physical commodities is stated differently for the Selling Fund and the Buying
Fund, RiverSource Investments does not believe this difference is material.

- RiverSource Mid Cap Value Fund will not buy or sell physical commodities
  unless acquired as a result of ownership of securities or other instruments,
  except this shall not prevent the Fund from buying or selling options and
  futures contracts or from investing in securities or other instruments backed
  by, or whose value is derived from, physical commodities.


                                       34



- RiverSource Partners Select Value Fund will not buy or sell physical
  commodities unless acquired as a result of ownership of securities or other
  instruments, except this shall not prevent the fund from buying or selling
  options, futures contracts and foreign currency or from investing in
  securities or other instruments backed by, or whose value is derived from,
  physical commodities.

COMPARISON OF NONFUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies (policies that may be changed without a
shareholder vote) of the Buying Fund. Both Funds are also subject to the
following nonfundamental policies:

- No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

- Up to 25% of the Fund's net assets may be invested in foreign investments.

COMPARISON OF PRINCIPAL RISK FACTORS

The principal investment risks associated with the Selling Fund and the Buying
Fund are substantially similar because the Funds have similar investment
objectives, principal investment strategies and investment policies. Although
both of the Funds have similar limitation with respect to foreign investing, the
Buying Fund currently has higher exposure to these types of investments and
therefore presents increased exposure to the risks of foreign investing. With
regards to investment policies, although the Buying Fund is required to invest
80% of its net assets in equity securities of medium-sized companies and the
Selling Fund does not have this investment requirement, which may present the
increased risk of investing in mid-sized companies for the Buying Fund,
currently both Funds have approximately the same exposure to investments in mid-
sized companies. In addition, the Selling Fund has the ability to buy and sell
foreign currency, which may present the increased risk of foreign investing, but
currently the Selling Fund does not hold any foreign currencies. The actual
risks of investing in each Fund depend on the securities held in each Fund's
portfolio and on market conditions, both of which change over time. The Funds
are subject to the principal investment risks described below.

RISKS OF FOREIGN INVESTING. Foreign securities are securities of issuers based
outside the United States. An issuer is deemed to be based outside the United
States if it is organized under the laws of another country. Foreign securities
are primarily denominated in foreign currencies. In addition to the risks
normally associated with domestic securities of the same type, foreign
securities are subject to the following foreign risks:

Country risk includes the political, economic, and other conditions of the
country. These conditions include lack of publicly available information, less
government oversight (including lack of accounting, auditing, and financial
reporting standards), the possibility of government-imposed restrictions, and
even the nationalization of assets. The liquidity of foreign investments may be
more limited than for most U.S. investments, which means that, at times it may
be difficult to sell foreign securities at desirable prices.

Currency risk results from the constantly changing exchange rate between local
currency and the U.S. dollar. Whenever the Fund holds securities valued in a
foreign currency or holds the currency, changes in the exchange rate add to or
subtract from the value of the investment.

Custody risk refers to the process of clearing and settling trades. It also
covers holding securities with local agents and depositories. Low trading
volumes and volatile prices in less developed markets make trades harder to
complete and settle. Local agents are held only to the standard of care of the
local market. Governments or trade groups may compel local agents to hold
securities in designated depositories that are not subject to independent
evaluation. The less developed a country's securities market is, the greater the
likelihood of problems occurring.

ISSUER RISK. An issuer may perform poorly, and therefore, the value of its
stocks and bonds may decline. Poor performance may be caused by poor management
decisions, competitive pressures, breakthroughs in technology, reliance on
suppliers, labor problems or shortages, corporate restructurings, fraudulent
disclosures or other factors.

MARKET RISK. The market value of securities may fall or fail to rise. Market
risk may affect a single issuer, sector of the economy, industry, or the market
as a whole. The market value of securities may fluctuate, sometimes rapidly and
unpredictably. This risk is generally greater for small and mid-sized companies,
which tend to be more vulnerable to adverse developments. In addition, focus on
a particular style, for example, investment in growth or value securities, may
cause the Fund to underperform other mutual funds if that style falls out of
favor with the market.

MID-SIZED COMPANY RISK. Investments in mid-sized companies often involve greater
risks than investments in larger, more established companies because mid-sized
companies may lack the management experience, financial resources, product
diversification and competitive strengths of larger companies. In addition, in
some instances the securities of mid-sized companies are traded only over-the-
counter or on regional securities exchanges and the frequency and volume of
their trading is substantially less than is typical of larger companies.


                                       35



SECTOR RISK. If a fund emphasizes one or more economic sectors, it may be more
susceptible to the financial, market or economic events affecting the particular
issuers and industries in which it invests than funds that do not emphasize
particular sectors. The more a fund diversifies across sectors, the more it
spreads risk and potentially reduces the risks of loss and volatility.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- how each Fund's average annual total returns compare to recognized measures of
  market performance shown in the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class I and Class R4 shares of RiverSource Partners
Select Value Fund. The second table shows total returns from hypothetical
investments in Class A, Class B, Class C, Class I and Class R4 shares of
RiverSource Mid Cap Value Fund. These returns are compared to the indexes shown
for the same periods. For purposes of the performance calculation in the table
we assumed:

- the maximum sales charge of 5.75% for Class A shares;

- sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B and Class C;

- no sales charge for Class I and Class R4 shares; and

- with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

The Russell Midcap Value Index, an unmanaged index, measures the performance of
the mid-cap value segment of the U.S. equity universe. It includes those Russell
Midcap Index companies with lower to price-to-book ratios and lower forecasted
growth values. The index reflects reinvestment of all distributions and changes
in market prices.

The Lipper Mid-Cap Value Funds Index includes the 30 largest mid-cap value funds
tracked by Lipper Inc. The index's returns include net reinvested dividends. The
Fund's performance is currently measured against this index for purposes of
determining the performance incentive adjustment.

Investors cannot invest directly in an index.

PROPOSAL 3. REORGANIZATION OF RIVERSOURCE PARTNERS SMALL CAP EQUITY FUND INTO
SELIGMAN SMALLER-CAP VALUE FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- Have RiverSource Investments as an investment manager.

- Have the same polices for buying and selling shares and the same exchange
  rights.

- Have the same distribution policies.

- Offer classes A, B, C, I and R4 (the Buying Fund also offers classes R2, R3
  and R5).

- Are structured as a series of capital stock of an open-end management
  investment company. The Selling Fund is organized as a series of a Minnesota
  corporation and the Buying Fund is organized as a series of a Maryland
  corporation. Please see Exhibit D to this proxy statement/prospectus for more
  information regarding the differences between the rights of shareholders of
  the Buying Fund and the shareholders of the Selling Fund.

COMPARISON OF INVESTMENT OBJECTIVES

Both Funds seek long-term capital appreciation. Both Funds are intended for
long-term investors and are not intended as short-term trading vehicle. Because
any investment involves risk, there is no assurance this objective can be
achieved. Only shareholders can change the Fund's objective.

The investment objectives for the Funds are as follows:

          SELLING FUND: RiverSource Partners Small Cap Equity Fund seeks to
                        provide shareholders with long-term growth of capital.

          BUYING FUND: Seligman Smaller-Cap Value Fund seeks long-term capital
                       appreciation.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests primarily in securities of companies with small market
capitalizations. The Selling Fund invests at least 80% of its net assets in
equity securities of small market companies, which are defined as companies that
have a market capitalization not greater than that of the largest company in the
Russell 2000 Index or the Standard & Poor's ("S&P") SmallCap 600 Index at the
time of investment by the Selling Fund. The Buying Fund invests at least 80% of
its net assets in value companies with market capitalizations of $3 billion or
less at the time of purchase. Each Fund may invest up to 25% of its net assets
in foreign investments.

Although RiverSource Investments serves as investment manager of both Funds, the
Selling Fund was, until Aug. 10, 2009, subadvised by American Century Investment
Management, Inc. (American Century), Jennison Associates LLC (Jennison) and Lord
Abbett & Co. LLC (Lord Abbett). The Selling Fund's Board of Directors terminated
the contracts of American Century, Jennison and Lord Abbett for managing the
Selling Fund's portfolio. Since Aug. 10, 2009, RiverSource Investments has
solely managed the Selling Fund.

Detailed strategies for the Selling Fund and the Buying Fund are set forth
below:

                                               security of a foreign issuer. ADRs are quoted
                                               and settled in U.S. dollars. The Fund uses
                                               the same criteria in evaluating these
                                               securities as it does for common stocks.

                                               The Fund may invest up to 15% of its net
                                               assets in illiquid securities (i.e.,
                                               securities that cannot be readily sold) and
                                               may invest up to 25% of its net assets in
                                               foreign investments. The Fund may also
                                               purchase put options in an attempt to hedge
                                               against a decline in the price of securities
                                               it holds in its portfolio. A put option gives
                                               the Fund the right to sell an underlying
                                               security at a particular price during a fixed
                                               period. The Fund generally does not invest a
                                               significant amount of its assets, if any, in
                                               illiquid securities, foreign securities, or
                                               put options.

                                               The Fund's Board of Directors may change the
                                               parameters by which small market
                                               capitalization is defined if it concludes
                                               such a change is appropriate.

--------------------------------------------------------------------------------------------
</Table>


In addition to the principal investment strategies set forth above, each Fund
also has the following principal investment strategies:

The Fund uses a bottom-up stock selection approach. This means that the
investment manager concentrates on individual company fundamentals, rather than
on a particular industry. In selecting investments, the investment manager seeks
to identify value companies that it believes display certain characteristics,
including but not limited to, one or more of the following:

- a low price-to-earnings and/or low price-to book ratio;

- positive change in senior management;

- positive corporate restructuring;

- a temporary setback in price due to factors that no longer exist;

- a positive shift in the company's business cycle; and/or

- a catalyst for increase in the rate of the company's earnings growth.

The Fund generally holds a small number of securities because the investment
manager believes doing so allows it to adhere to its disciplined value
investment approach. The investment manager maintains close contact with the
management of each company in which the Fund invests or the third-party analysts
covering such companies, and continually monitors Fund holdings, remaining
sensitive to overvaluation and deteriorating fundamentals.

In deciding whether to sell a security, the investment manager considers
whether:

- it has become fully valued,

- its fundamentals have deteriorated, or

- ongoing evaluation reveals that there are more attractive investment
  opportunities available.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed. For purposes of this
discussion, a "fundamental" investment policy is one that may not be changed
without a shareholder vote. The Funds' fundamental investment policies are set
forth below:

----------------------------------------------------------------------------------------------------



COMPARISON OF NONFUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies (policies that may be changed without a
shareholder vote) of the Buying Fund. Both Funds are also subject to the
following nonfundamental policies:

- No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

- Up to 25% of the Fund's net assets may be invested in foreign investments.

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives, principal investment strategies and
investment policies. The actual risks of investing in each Fund depend on the
securities held in each Fund's portfolio and on market conditions, both of which
change over time. Both Funds are subject to the principal investment risks
described below.

     Each Fund is actively managed and its performance therefore will reflect in
     part the ability of the portfolio manager to select securities and to make
     investment decisions that are suited to achieving the Fund's investment
     objective. Due to its active management, the Fund could underperform other
     mutual funds with similar investment objectives.

     Investments in smaller companies typically involve greater risks than
     investments in larger companies. Small company stocks, as a whole, may
     experience larger price fluctuations than large company stocks or other
     types of investments. Small companies tend to have shorter operating
     histories and may have less experienced management and limited product
     lines, markets and financial or managerial resources.

     Each Fund's performance may be affected by the broad investment environment
     in the United States or international securities markets, which is
     influenced by, among other things, interest rates, inflation, politics,
     fiscal policy, and current events.

     Each Fund may not invest 25% or more of its total assets in securities of
     companies in any one industry. However, each Fund may invest a substantial
     percentage of its assets in certain industries or economic sectors believed
     to offer good investment opportunities. If an industry or economic sector
     in which the Fund is invested falls out of favor, the Fund's performance
     may be negatively affected. This effect may be heightened if the Fund holds
     a smaller number of securities.

     Each Fund has historically held a small number of securities. Consequently,
     if one or more of the securities held in a Fund's portfolio declines in
     value or underperforms relative to the market, it may have a greater impact
     on the Fund's

                                       42



     performance than if the Fund held a larger number of securities. The Funds
     may experience more volatility, especially over the short term, than a fund
     with a greater number of holdings.

     Foreign securities in the Fund's portfolios involve higher risk and may
     subject the Fund to higher price volatility. Investing in securities of
     foreign issuers involves risks not associated with U.S. investments,
     including currency fluctuations, local withholding and other taxes,
     different financial reporting practices and regulatory standards, high
     costs of trading, changes in political conditions, expropriation,
     investment and repatriation restrictions, and settlement and custody risks.

     In addition to the risks described above, the Buying Fund is subject to the
     additional principal investment risks set forth below. While these
     additional risks may also be risks of the Selling Fund, they are not stated
     as principal investment risks of the Selling Fund. For more information
     regarding the Selling Fund's principal investment risks, see "Principal
     Risks" in the Selling Fund's prospectus.

     Value stocks involve the risk that they may never reach what the investment
     manager believes is their full market value either because the market fails
     to recognize the stock's intrinsic worth or the investment manager
     misgauged that worth. They also may decline in price, even though in theory
     they are already undervalued. Because different types of stocks tend to
     shift in and out of favor depending on market and economic conditions, the
     Fund's performance may sometimes be lower or higher than that of other
     types of funds (such as those emphasizing growth stocks).

     Illiquid securities or derivatives (including options, rights, and
     warrants) in the Fund's portfolio involve higher risk and may subject the
     Fund to higher price volatility.

     Option transactions can involve a high degree of risk, including the
     possibility of a total loss of the amount invested or more. When options
     are purchased in the over-the-counter markets, there are additional risks,
     such as counterparty and liquidity risks.

     There are special risks associated with investing in preferred stocks and
     securities convertible into common stocks. Preferred stocks may be subject
     to, among other things, deferral of distribution payments, involuntary
     redemptions, subordination to bonds and other debt instruments of the
     issuer, a lack of liquidity relative to other securities such as common
     stocks, and limited voting rights. The market value of securities
     convertible into common stocks tends to decline as interest rates increase
     and, conversely, tends to increase as interest rates decline. In addition,
     because of the conversion feature, the market value of convertible
     securities tends to vary with fluctuations in the market value of the
     underlying common stock.

     The Fund may invest a portion of its net assets in debt securities, which
     may be subject to changes in interest rates, the creditworthiness of the
     issuers, unanticipated prepayment, and the decline of the bond market in
     general.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- how each Fund's average annual total returns compare to recognized measures of
  market performance shown in the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class I and Class R4 shares of RiverSource Partners
Small Cap Equity Fund. The second table shows total returns from hypothetical
investments in Class A, Class B and Class C shares of Seligman Smaller-Cap Value
Fund. Inception date for Class I and Class R4 shares for Seligman Smaller-Cap
Value Fund is Aug. 3, 2009 and they have not been in existence for a full
calendar year, therefore performance information is not shown. These returns are
compared to the indexes shown for the same periods. For purposes of the
performance calculation in the table we assumed:

- the maximum sales charge of 5.75% for Class A shares;

- sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B and Class C;

- no sales charge for RiverSource Partners Small Cap Equity Fund Class I; and

- with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.


                                       43



AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

 *  Effective Jan. 7, 2008, the maximum initial sales charge on investments in
    Class A shares of less than $50,000 is 5.75%. Although for all periods
    presented in the table the Fund's Class A total returns reflect a 5.75%
    initial sales charge, the actual returns for periods prior to Jan. 7, 2008
    would have been higher if a 4.75% maximum initial sales charge then in
    effect was incurred.
**  Effective June 4, 2007, there is no initial sales change on purchases of
    Class C shares. Although for all periods presented in the table the Fund's
    Class C share returns do not reflect an initial sales charge, the actual
    returns for periods prior to June 4, 2007 would have been lower if a 1.00%
    maximum initial sales charge then in effect was incurred.

The Russell 2000 Value Index is an unmanaged benchmark that assumes the
reinvestment of all distributions, if any and excludes the effect of expenses,
fees, sales charges and taxes. The Russell 2000 Value Index measures the
performance of those Russell 2000 companies (small-cap value segment of the U.S.
equity universe) with lower price-to-book ratios and lower forecasted growth
values, as determined by the Frank Russell Company.

The Lipper Small-Cap Core Funds Index (the Lipper Index) includes the 30 largest
small-cap core funds tracked by Lipper Inc. The index's returns include net
reinvested dividends.

The Lipper Small-Cap Value Funds Index (the Lipper Index) includes the 30
largest small-cap value funds tracked by Lipper Inc. The index's returns include
net reinvested dividends.

The Lipper Small-Cap Value Funds Average (the Lipper Average) is an unmanaged
benchmark that assumes the reinvestment of all distributions, if any and
excludes the effect of fees, sales charges and taxes. The Lipper Small-Cap Value
Funds Average measures the performance of funds that, by portfolio practice,
invest at least 75% of their equity assets in companies with market
capitalizations (on a three-year weighted basis) below Lipper's USDE small-cap
ceiling. Small-cap value funds typically have a below-average price-to-earnings
ratio, price-to-book ratio and three-year sales-per-share growth value compared
to the S&P Small Cap 600 Index.

The Lipper Small-Cap Core Funds Average (the Lipper Average) is an unmanaged
benchmarks that assume the reinvestment of all distributions, if any and
excludes the effect of fees, sales charges and taxes. The Lipper Small-Cap Core
Funds Average measure the performance of funds that, by portfolio practice,
invest at least 75% of their equity assets in companies with market
capitalizations (on a three-year weighted basis) below Lipper's USDE small-cap
ceiling. Small-cap core funds typically have an average price-to-earnings ratio,
price to-book ratio and three-year sales-per-share growth value, compared to the
S&P SmallCap 600 Index.

As of the date of this proxy statement/prospectus, Lipper classifies the Fund as
a Small-Cap Core Fund. Investors cannot invest directly in an average or an
index.

For Seligman Smaller-Cap Value Fund, on [date], the Lipper Index replaced the
Lipper Average as the Fund's secondary benchmark. The Lipper Average includes
all funds categorized by Lipper within the broad universe of funds in the Lipper
Average, whereas the Lipper Index includes only a select peer group from the
Lipper Average, as described above. This change was made to bring the selection
of the Seligman Fund secondary benchmarks in line with the practice of the
RiverSource Family of Funds, which would permit a common shareholder experience
and provide a more focused peer group for performance comparison purposes.
Information on both the Lipper Index and the Lipper Average will be included for
a one-year transition period. Thereafter, only the Lipper Index will be
included.

PROPOSAL 4. REORGANIZATION OF RIVERSOURCE PARTNERS SMALL CAP GROWTH FUND INTO
SELIGMAN FRONTIER FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- Have RiverSource Investments as an investment manager.

- Have the same polices for buying and selling shares and the same exchange
  rights.

- Have the same distribution policies.

- Offer the same classes of shares: A, B, C, I, R2, R3, R4 and R5.

- Are structured as a series of capital stock of an open-end management
  investment company. The Selling Fund is organized as a series of a Minnesota
  corporation and the Buying Fund is organized as a Maryland corporation. Please
  see Exhibit D to this proxy statement/prospectus for more information
  regarding the differences between the rights of shareholders of the Buying
  Fund and the shareholders of the Selling Fund.

COMPARISON OF INVESTMENT OBJECTIVES

Both Funds seek growth of capital. Both Funds are intended for long-term
investors and are not intended as a short-term trading vehicle. Because any
investment involves risk, there is no assurance this objective can be achieved.
Only shareholders can change the Fund's objective.

The investment objectives for the Funds are as follows:

          SELLING FUND: RiverSource Partners Small Cap Growth Fund seeks to
                        provide shareholders with long-term capital growth.

          BUYING FUND: Seligman Frontier Fund seeks to provide shareholders with
                       growth of capital. Income may be considered but is
                       incidental to the Fund's investment objective.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests primarily in equity securities of small U.S. companies with
market capitalizations of up to $2 billion or less at the time of purchase by
the Fund. The Selling Fund, with respect to its 80% policy, may also invest in
companies that have market capitalizations that fall within the range of those
included in the Russell 2000 Growth Index. While the Selling Fund invests at
least 80% of its net assets in small cap companies, the Buying Fund invests at
least 65% of its net assets in small cap companies.

Although RiverSource Investments serves as investment manager of both Funds, the
Selling Fund was, until Aug. 10, 2009, subadvised by Essex Investment Management
(Essex) and UBS Global Asset Management (UBS). The Selling Fund's Board of
Directors terminated the subadvisory contracts of Essex and UBS for managing the
Selling Fund's portfolio. Since Aug. 10, 2009, RiverSource Investments has
solely managed the Selling Fund.


                                       47



Detailed strategies for the Selling Fund and the Buying Fund are set forth
below:

RIVERSOURCE PARTNERS SMALL CAP GROWTH FUND
(SELLING FUND)                                 SELIGMAN FRONTIER FUND (BUYING FUND)
--------------------------------------------------------------------------------------------
                                            
The Fund's assets primarily are invested in    Although the Fund may invest in the

2000 Growth Index. The Fund will provide       time of purchase by the Fund, of $2 billion
shareholders with at least 60 days' notice of  or less).
any change in the 80% policy.
                                               The Fund invests primarily in common stocks;
                                               however, it may also invest in preferred
                                               stocks, securities convertible into common
                                               stocks, and stock purchase warrants if the
                                               investment manager believes these investments
                                               offer capital growth opportunities. The Fund
                                               may also invest in American Depositary
                                               Receipts ("ADRs"), which are publicly-traded
                                               instruments generally issued by domestic
                                               banks or trust companies that represent a
                                               security of a foreign issuer. ADRs are quoted
                                               and settled in U.S. dollars. The Fund uses
                                               the same criteria in evaluating these
                                               securities as it does for common stocks.

                                               The Fund may invest up to 15% of its net
                                               assets in illiquid securities (i.e.,
                                               securities that cannot be readily sold) and
                                               may invest up to 25% of its total assets
                                               directly in foreign securities. The Fund may
                                               also purchase put options in an attempt to
                                               hedge against a decline in the price of
                                               securities that it holds. A put option gives
                                               the Fund the right to sell an underlying
                                               security at a particular price during a fixed
                                               period of time. The Fund generally does not
                                               invest a significant amount of its assets, if
                                               any, in illiquid securities, foreign
                                               securities or put options.

                                               The Fund intends to comply with Rule 4.5 of
                                               the Commodity Futures Trading Commission
                                               (CFTC), under which a mutual fund is exempt
                                               from the definition of a "commodity pool
                                               operator." The Fund, therefore, is not
                                               subject to registration or regulation as a
                                               pool operator, meaning that the Fund may
                                               invest in futures contracts without
                                               registering with the CFTC.

                                               The Fund's investment objective may be
                                               changed only with shareholder approval. The
                                               principal investment strategies may be
                                               changed without shareholder approval. Any
                                               changes to these strategies, however, must be
                                               approved by the Fund's Board of Directors.
                                               The Fund's Board of Directors may change the
                                               parameters by which "small companies" are
                                               defined if it concludes that such a change is
                                               appropriate.

--------------------------------------------------------------------------------------------
</Table>


In addition to the principal investment strategies set forth above, each Fund
also has the following principal investment strategies:

The Fund uses a bottom-up stock selection approach. This means that the
investment manager concentrates on individual company fundamentals, rather than
on a particular market sector. The investment manager may select investments for
either their short-, medium or long-term prospects. In selecting investments for
the Fund, the investment manager maintains a disciplined investment process that
focuses on downside risks as well as upside potential and seeks to identify
companies that it believes display attractive growth, profitability or valuation
characteristics, including one or more of the following:

- Positive earnings and/or earnings growth rate

- Positive revenue growth

- Positive operating cash flows

- Quality management

- Unique competitive advantages

In deciding whether to sell a security, the investment manager considers
whether:

- its target price is reached,

- its valuation becomes excessive,

- its earnings or revenue growth are disappointing,

- its underlying fundamentals have deteriorated, or

- more attractive investment opportunities are believed to be available.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed. For purposes of this
discussion, a "fundamental" investment policy is one that may not be changed
without a shareholder vote. The Funds' fundamental investment policies are set
forth below:

----------------------------------------------------------------------------------------------------



COMPARISON OF NONFUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies (policies that may be changed without a
shareholder vote) of the Buying Fund. Both Funds are also subject to the
following nonfundamental policies:

- No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

- Up to 25% of the Fund's net assets may be invested in foreign investments.

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives and principal investment strategies.
However, the Selling Fund may expose shareholders to a greater risk of investing
in small capitalization companies than the Buying Fund due to the Selling Fund's
investment strategy of investing at least 80% of its net assets in securities of
small capitalization companies, while the Buying Fund's investment strategy is
to invest at least 65% of its net assets in securities of small capitalization
companies. The actual risks of investing in each Fund depend on the securities
held in each Fund's portfolio and on market conditions, both of which change
over time. Both Funds are subject to the principal investment risks described
below.

     Stock prices fluctuate. Therefore, as with any fund that invest in stocks,
     the Fund's net asset value will fluctuate, especially in the short term.
     You may experience a decline in the value of your investment and you could
     lose money if you sell your shares at a price lower than you paid for them.

     The Fund's performance may be affected by the broad investment environment
     in the United States or international securities markets, which is
     influenced by, among other things, interest rates, inflation, politics,
     fiscal policy, and current events.

     Foreign securities in the Fund's portfolio involve higher risk and may
     subject the Fund to higher price volatility. Investing in securities of
     foreign issuers involves risks not associated with U.S. investments,
     including currency fluctuations, local withholding and other taxes,
     different financial reporting practices and regulatory standards, high
     costs of trading, changes in political conditions, expropriation,
     investment and repatriation restrictions, and settlement and custody risks.

     The Fund is actively managed and its performance therefore will reflect in
     part the ability of the portfolio manager to select securities and to make
     investment decisions that are suited to achieving the Fund's investment
     objectives. Due to their active management, the Fund could underperform
     other mutual funds with similar investment objectives.


                                       50



     The Fund may actively and frequently trade securities in its portfolio to
     carry out its principal strategies. A high portfolio turnover rate
     increases transaction costs, which may increases the Fund's expenses.
     Frequent and active trading may also cause adverse tax consequences for
     investors in the Fund due to increase in short-term capital gains.

     Small-company stocks, as a whole, may experience larger price fluctuations
     than large-company stocks or other types of investments. Small companies
     tend to have shorter operating histories and may have less experienced
     management and limited product lines, markets and financial and managerial
     resources. During periods of investor uncertainty, investor sentiment may
     favor large, well-known companies over small, lesser-known companies.

     In addition to the risks described above, the Buying Fund is subject to the
     additional principal investment risks set forth below. While these
     additional risks may also be risks of the Selling Fund, they are not stated
     as principal investment risks of the Selling Fund. For more information
     regarding the Selling Fund's principal investment risks, see "Principal
     Risks" in the Selling Fund's prospectus.

     Derivatives (including rights and warrants) and illiquid securities in the
     Fund's portfolio involve higher risk and may subject the Fund to higher
     price volatility.

     The Fund may not invest 25% or more of its total assets in securities of
     companies in any one industry. The Fund may, however, invest a substantial
     percentage of its assets in certain industries or economic sectors believed
     by the investment manager to offer good investment opportunities. If an
     industry or economic sector in which the Fund is invested falls out of
     favor, the Fund's performance may be negatively affected.

     There are special risks associated with investing in preferred stocks and
     securities convertible into common stocks. Preferred stocks may be subject
     to, among other things, deferral of distribution payments, involuntary
     redemptions, subordination to bonds and other debt instruments of the
     issuer, a lack of liquidity relative to other securities such as common
     stocks, and limited voting rights. The market value of securities
     convertible into common stocks tends to decline as interest rates increase
     and, conversely, tends to increase as interest rates decline. In addition,
     because of the conversion feature, the market value of convertible
     securities tends to vary with fluctuations in the market value of the
     underlying common stock.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- how each Fund's average annual total returns compare to recognized measures of
  market performance shown in the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4 and Class R5
shares of RiverSource Partners Small Cap Growth Fund. The second table shows
total returns from hypothetical investments in Class A, Class B, Class C, Class
R2 (formerly Class R) and Class R5 (formerly Class I) shares of Seligman
Frontier Fund. Inception date for Class I, Class R3 and Class R4 shares of
Seligman Frontier Fund is Aug. 3, 2009 and they have not been in existence for a
full calendar year, therefore performance information is not shown. These
returns are compared to the indexes shown for the same periods. For purposes of
the performance calculation in the table we assumed:

- the maximum sales charge of 5.75% for Class A shares;

- sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B and Class C;

- no sales charge for RiverSource Partners Small Cap Growth Fund Class I, Class
  R2, Class R3, Class R4 and Class R5 shares and for Seligman Frontier Fund
  Class R2 and Class R5 shares; and

- with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.


                                       51



AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

 *  Effective Jan. 7, 2008, the maximum initial sales charge on investments in
    Class A shares of less than $50,000 is 5.75%. Although for all periods
    presented in the table the Fund's Class A total returns reflect a 5.75%
    initial sales charge, the actual returns for periods prior to Jan. 7, 2008
    would have been higher if a 4.75% maximum initial sales charge then in
    effect was incurred.
**  Effective June 4, 2007, there is no initial sales change on purchases of
    Class C shares. Although for all periods presented in the table the Fund's
    Class C share returns do not reflect an initial sales charge, the actual
    returns for periods prior to June 4, 2007 would have been lower if a 1.00%
    maximum initial sales charge then in effect was incurred.

The Russell 2000 Growth Index ("Russell Index") is an unmanaged benchmark that
assumes the reinvestment of all distributions, if any and excludes the effect of
expenses, fees, sales charges and taxes. The Russell Index measures the
performance of small-company growth stocks, as determined by the Frank Russell
Company.

The Lipper Small-Cap Growth Funds Index (Lipper Index) includes the 30 largest
small-cap growth funds tracked by Lipper Inc. The index's returns include net
reinvested dividends.

The Lipper Small-Cap Growth Funds Average (Lipper Average) is an unmanaged
benchmark that assumes the reinvestment of all distributions, if any and
excludes the effect of fees, sales charges and taxes. The Lipper Small-Cap
Growth Funds Average is an average of all funds that invest at least 75% of
their equity assets in companies with market capitalizations (on a three-year
weighted basis) below Lipper's U.S. Diversified Equity Small-Cap ceiling ($3.8
billion as of [December 31, 2008]). Small-cap growth funds typically have an
above-average price-to-earnings ratio, price-to-book ratio, and three-year
sales-per-share growth value compared to the S&P SmallCap 600 Index.

Investors cannot invest directly in an average or an index.

For Seligman Frontier Fund, on Nov. 1, 2009, the Lipper Index replaced the
Lipper Average as the Fund's secondary benchmark. The Lipper Average includes
all funds categorized by Lipper within the broad universe of funds in the Lipper
Average, whereas the Lipper Index includes only a select peer group from the
Lipper Average, as described above. This change was made to bring the selection
of the Seligman Fund secondary benchmarks in line with the practice of the
RiverSource Family of Funds, which would permit a common shareholder experience
and provide a more focused peer group for performance comparison purposes.
Information on both the Lipper Index and the Lipper Average will be included for
a one-year transition period. Thereafter, only the Lipper Index will be
included.

PROPOSAL 5. REORGANIZATION OF SELIGMAN GLOBAL SMALLER COMPANIES FUND INTO
RIVERSOURCE PARTNERS INTERNATIONAL SMALL CAP FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- Have RiverSource Investments as an investment manager; however, the Selling
  Fund is subadvised by Wellington Management Company, LLP and the Buying Fund
  is subadvised by Batterymarch Financial Management, Inc. and Columbia Wanger
  Asset Management, L.P.

- Have the same policies for buying and selling shares and the same exchange
  rights.

- Have the same distribution policies.

- Offer classes A, B, C, R2 and R5 (the Buying Fund also offers classes I and
  R4).

- Are structured as a series of an open-end management investment company. The
  Buying Fund is a series of a Minnesota corporation, whereas the Selling Fund
  is a series of a Maryland corporation. Please see Exhibit D to this proxy
  statement/prospectus for more information regarding the differences between
  the rights of shareholders of the Buying Fund and the shareholders of the
  Selling Fund.

COMPARISON OF INVESTMENT OBJECTIVES

Both Funds seek growth of capital. Both Funds are intended for long-term
investors and are not intended as short-term trading vehicle. Because any
investment involves risk, there is no assurance the Fund's objective can be
achieved. Only shareholders can change the Fund's objective.

The investment objectives for the Funds are as follows:

          SELLING FUND: Seligman Global Smaller Companies Fund seeks long-term
                        capital appreciation.

          BUYING FUND: RiverSource Partners International Small Cap Fund seeks
                       to provide shareholders with long-term growth of capital.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Both Funds invest in equity securities of smaller non-U.S. companies. However,
the Selling Fund invests 80% in smaller U.S. and non-U.S. companies and may
invest in companies domiciled in any country, although it typically invests in
developed countries, whereas the Buying Fund invests 80% in small companies
whose market capitalization falls within the range of capitalization of
companies in the S&P Global ex-U.S. Small Cap Index and may invest in mature
markets and in emerging markets. The Selling Fund generally will invest at least
40% of its net assets in companies that maintain their principal place of
business or conduct their principal business activities outside the U.S., have
their securities traded on non-U.S. exchanges or have been formed under the laws
of non-U.S. countries, while the Buying Fund invests primarily in equity
securities of non-U.S. companies.

RiverSource Investments serves as the investment manager for both Funds and is
responsible for the oversight of the Fund's subadviser(s) which provide day-to-
day management of the Fund. The Selling Fund is subadvised by Wellington
Management Company, LLP and the Buying Fund is subadvised by Batterymarch
Financial Management, Inc. ("Batterymarch") and Columbia Wanger Asset
Management, L.P. ("Columbia WAM") (collectively, the "Subadvisers").

Detailed investment strategies for the Selling Fund and the Buying Fund are set
forth below:

SELIGMAN GLOBAL SMALLER COMPANIES FUND (SELLING FUND)

The Fund generally invests at least 80% of its assets in equity securities of
smaller U.S. and non-U.S. companies. The Fund may invest in companies domiciled
in any country, although it typically invests in developed countries. Relative
to its benchmark, the Fund is generally neutrally weighted across the major
geographic regions. Shareholders will be provided with at least 60 days prior
written notice of any change to the 80% investment policy.

Under normal market conditions, the Fund generally will invest at least 40% of
its net assets in companies that maintain their principal place of business or
conduct their principal business activities outside the U.S., have their
securities traded on non-U.S. exchanges or have been formed under the laws of
non-U.S. countries. The portfolio manager may reduce this 40% minimum investment
amount to 30% if it believes that market conditions for these types of companies
or specific foreign markets are unfavorable. The Fund considers a company to
conduct its principal business activities outside the U.S. if it derives at
least 50% of its revenue from business outside the U.S. or has at least 50% of
its assets outside the U.S.

The Fund uses an investment approach that is bottom-up focused, looking for both
extended growth opportunities and special situations (including value stocks)
within each region.


                                       55



In selecting individual securities, the portfolio managers look for companies
that they believe display the following characteristics:

- Extended growth opportunities or special situations where there is a potential
  for improvement in overall operations

- A well articulated and believable business model

- Quality management

- Sustainable competitive advantage

- Strong financial characteristics

The Fund generally sells a stock if the portfolio managers believe its target
price has been reached, its earnings are disappointing, its revenue or earnings
growth has slowed, its underlying fundamentals have deteriorated, or the
portfolio managers are finding better opportunities elsewhere. The Fund may also
sell a stock if the portfolio managers believe that negative country or regional
factors may affect a company's outlook, to manage risk in the Fund, or to meet
cash requirements.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the U.S. dollar. The Fund normally
concentrates its investments in common stocks; however, it may invest in other
types of equity securities, including securities convertible into or
exchangeable for common stock, depositary receipts, and rights and warrants to
purchase common stock. The Fund also may invest up to 20% of its assets in
preferred stock and investment-grade or comparable quality debt securities.

The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold), and may from time to time enter into
forward foreign currency exchange contracts in an attempt to manage the risk of
adverse changes in currencies. The Fund may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds in its
portfolio. A put option gives the Fund the right to sell an underlying security
at a particular price during a fixed period of time. Forward foreign currency
exchange contracts and put options on securities may not be available to the
Fund on reasonable terms in many situations and the Fund may frequently choose
not to enter into such contracts or purchase such options even when they are
available.

The Fund may invest in futures contracts. The Fund intends to comply with Rule
4.5 of the Commodity Futures Trading Commission (CFTC), under which a mutual
fund is exempt from the definition of a "commodity pool operator." The Fund,
therefore, is not subject to registration or regulation as a pool operator,
meaning that the Fund may invest in futures contracts without registering with
the CFTC.

The Fund may also invest up to 10% of its assets in exchange-traded funds
(ETFs). ETFs are traded, like individual stocks, on an exchange, but they
represent baskets of securities that seek to track the performance of certain
indices. The indices include not only broad-market indices but more specific
indices as well, including those relating to particular sectors, countries and
regions. The Fund may invest in ETFs for short-term cash management purposes or
as part of its overall investment strategy.

The Fund may, from time to time, take temporary defensive positions that are
inconsistent with its principal strategies (e.g., investing less than 30% of its
assets in companies outside the U.S.) in seeking to minimize extreme volatility
caused by adverse market, economic, political, or other conditions. This could
prevent the Fund from achieving its objective.

RIVERSOURCE PARTNERS INTERNATIONAL SMALL CAP FUND (BUYING FUND)

The Fund invests primarily in equity securities of non-U.S. companies. Under
normal market conditions, the Fund will invest at least 80% of its net assets
(including any borrowings for investment purposes) in the stocks of small
companies. The Fund considers small companies to be those whose market
capitalization falls within the range of companies in the S&P Global ex-U.S.
Small Cap Index. The market capitalization within the Index will vary. Over
time, the capitalizations of the companies in the Index will change. As they do,
the size of the companies in which the Fund invests may change. As long as an
investment continues to meet the Fund's other investment criteria, the Fund may
choose to continue to hold a stock even if the company's market capitalization
grows beyond the market capitalization of the largest company held within the
Index or falls below the market capitalization of the smallest company held
within the Index. The Fund may invest in mature markets (such as the United
Kingdom, Canada, and Japan) and in emerging markets (such as Korea, Mexico, and
Russia). The Fund will hold both growth and value stocks and at times may favor
one more than the other based on available opportunities. The Fund will provide
shareholders with at least 60 days' notice of any change in the 80% policy.

RiverSource Investments serves as the investment manager to the Fund and is
responsible for the oversight of the Fund's subadvisers, Batterymarch and
Columbia WAM, which provide day-to-day management for the Fund. RiverSource
Investments, subject to the oversight of the Fund's Board, decides the
proportion of the Fund assets to be managed by each subadviser, and may change
these proportions at any time. The two Subadvisers act independently of each
other and use their

                                       56



own methodology for selecting investments. The two Subadvisers employ an active
investment strategy that focuses on companies that the asset manager believes
will increase in value over time.

BATTERYMARCH

Batterymarch uses disciplined, systematic techniques to analyze a very broad
universe of approximately 2,500 liquid stocks. All 2,500 liquid stocks are
ranked on a daily basis across five fundamental dimensions: cash flow, earnings
growth, expectations, value and technicals. Decisions to buy or sell particular
stocks are based on their daily rankings; the best-ranked stocks are bought,
while those that rank poorly are sold. Batterymarch determines region/sector
allocations using proprietary models that incorporate both bottom-up stock data
and the opinions of the investment team. Region/sector exposures are controlled
for purposes of risk management.

Batterymarch may use foreign currency futures contracts or foreign currency
forward contracts, with terms of up to six months in an effort to hedge existing
positions or currency fluctuations. Batterymarch also may purchase foreign
currency for immediate settlement in order to purchase foreign securities.

COLUMBIA WAM

Columbia WAM invests primarily in stocks of small- and medium-sized companies
based both outside and in the U.S. with capitalizations of less than $5 billion
at the time of purchase. Columbia WAM may choose to hold the stock even if it
grows beyond that capitalization limit. Columbia WAM believes that companies
with market capitalizations of less than $5 billion, which are not as well known
by financial analysts as larger companies, may offer higher return potential
than stocks of larger companies. Columbia WAM invests in the stocks of foreign
companies in developed markets (for example, Japan, Canada and the United
Kingdom) and in emerging markets (for example, China, India and Brazil).

In making investments for the Fund, Columbia WAM typically looks for companies
with:

- A strong business franchise that offers growth potential.

- Products and services that give a company a competitive advantage.

- A stock price that Columbia WAM believes is reasonable relative to the assets
  and earning power of the company.

Columbia WAM may sell a portfolio holding if the security reaches Columbia WAM's
price target, if the company has a deterioration of fundamentals, such as
failing to meet key operating benchmarks or if Columbia WAM believes other
securities are more attractive. Columbia WAM also may sell a portfolio holding
to fund redemptions.

Columbia WAM may use foreign currency futures contracts or foreign currency
forward contracts, with terms of up to one year in an effort to hedge existing
positions, interest rate fluctuations or currency fluctuations. Columbia WAM
also may purchase foreign currency for intermediate settlement in order to
purchase foreign securities.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material differences in the way the Funds have been
managed or in the way the combined Fund will be managed. For purposes of this
discussion, a "fundamental" investment policy is one that may not be changed
without a shareholder vote. The Funds' fundamental investment policies are set
forth below:

COMPARISON OF NONFUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies (policies that may be changed without
shareholder vote) of the Buying Fund. RiverSource Investments does not believe
that the differences

                                       58



between the nonfundamental policies of the Funds result in any material
differences in the way the Funds have been managed or in the way the combined
Fund will be managed. The following highlights the differences in the Funds'
nonfundamental investment policies.

---------------------------------------------------------------------------------------------------



COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because both
Funds have similar investment objectives, principal investment strategies and
investment policies. With regard to investment strategies, the Buying Fund may
expose shareholders to greater foreign risk due to the Buying Fund's greater
ability to invest predominantly in equity securities of non-U.S. companies. Also
the Selling Fund currently has greater exposure to emerging market and illiquid
securities and therefore may expose shareholders to greater emerging market and
liquidity risks. The actual risks of investing in each Fund depend on the
securities held in each Fund's portfolio and on market conditions, both of which
change over time. Both Funds are subject to the principal investment risks
described below:

- ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
  therefore will reflect in part the ability of the portfolio managers to select
  securities and to make investment decisions that are suited to achieving the
  Fund's investment objective. Due to its active management, the Fund could
  underperform other mutual funds with similar investment objectives.


                                       59



- DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial loss
  for the Fund. In addition to the potential for increased losses, the use of
  derivative instruments may lead to increased volatility within the Fund.
  Derivative instruments in which the Fund invests will typically increase the
  Fund's exposure to Principal Risks to which it is otherwise exposed, and may
  expose the Fund to additional risks, including correlation risk, counterparty
  credit risk, hedging risk, leverage risk and liquidity risk.

 Correlation risk is related to hedging risk and is the risk that there may be
 an incomplete correlation between the hedge and the opposite position, which
 may result in increased or unanticipated losses.

 Counterparty credit risk is the risk that a counterparty to the derivative
 instrument becomes bankrupt or otherwise fails to perform its obligations due
 to financial difficulties, and the Fund may obtain no recovery of its
 investment or may only obtain a limited recovery, and any recovery may be
 delayed.

 Hedging risk is the risk that derivative instruments used to hedge against an
 opposite position may offset losses, but they may also offset gains. There is
 no guarantee that a hedging strategy will eliminate the risk which the hedging
 strategy is intended to offset, which may lead to losses within the Fund.

 Leverage risk is the risk that losses from the derivative instrument may be
 greater than the amount invested in the derivative instrument.

 Liquidity risk, as described as a Principal Risk below, may be increased for
 derivative instruments which are not traded on an exchange, including, but not
 limited to, forward contracts, swaps and over-the-counter options.

 Certain derivatives have the potential for unlimited losses, regardless of the
 size of the initial investment.

- RISKS OF FOREIGN INVESTING. Foreign securities are securities of issuers based
  outside the United States. An issuer is deemed to be based outside the United
  States if it is organized under the laws of another country. Foreign
  securities are primarily denominated in foreign currencies. In addition to the
  risks normally associated with domestic securities of the same type, foreign
  securities are subject to the following foreign risks:

 Country risk includes the political, economic, and other conditions of the
 country. These conditions include lack of publicly available information, less
 government oversight (including lack of accounting, auditing, and financial
 reporting standards), the possibility of government-imposed restrictions, and
 even the nationalization of assets. The liquidity of foreign investments may be
 more limited than for most U.S. investments, which means that, at times it may
 be difficult to sell foreign securities at desirable prices.

 Currency risk results from the constantly changing exchange rate between local
 currency and the U.S. dollar. Whenever the Fund holds securities valued in a
 foreign currency or holds the currency, changes in the exchange rate add to or
 subtract from the value of the investment.

 Custody risk refers to the process of clearing and settling trades. It also
 covers holding securities with local agents and depositories. Low trading
 volumes and volatile prices in less developed markets make trades harder to
 complete and settle. Local agents are held only to the standard of care of the
 local market. Governments or trade groups may compel local agents to hold
 securities in designated depositories that are not subject to independent
 evaluation. The less developed a country's securities market is, the greater
 the likelihood of problems occurring.

 Emerging markets risk includes the dramatic pace of change (economic, social
 and political) in these countries as well as the other considerations listed
 above. These markets are in early stages of development and are extremely
 volatile. They can be marked by extreme inflation, devaluation of currencies,
 dependence on trade partners, and hostile relations with neighboring countries.

- ISSUER RISK. An issuer may perform poorly, and therefore, the value of its
  stocks and bonds may decline. Poor performance may be caused by poor
  management decisions, competitive pressures, breakthroughs in technology,
  reliance on suppliers, labor problems or shortages, corporate restructurings,
  fraudulent disclosures or other factors.

- LIQUIDITY RISK. Liquidity risk is the risk associated from a lack of
  marketability of securities which may make it difficult or impossible to sell
  at desirable prices in order to minimize loss. The Fund may have to lower the
  selling price, sell other investments, or forego another, more appealing
  investment opportunity.

- MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably. This risk is generally greater for small and mid-
  sized companies, which tend to be more vulnerable to adverse

                                       60



  developments. In addition, focus on a particular style, for example,
  investment in growth or value securities, may cause the Fund to underperform
  other mutual funds if that style falls out of favor with the market.

- SMALL COMPANY RISK. Investments in small capitalization companies often
  involve greater risks than investments in larger, more established companies
  because small capitalization companies may lack the management experience,
  financial resources, product diversification, experience and competitive
  strengths of larger companies. In addition, in many instances the securities
  of small capitalization companies are traded only over-the-counter or on
  regional securities exchanges and the frequency and volume of their trading is
  substantially less and may be more volatile than is typical of larger
  companies.

- SECTOR RISK. Companies that operate in different but closely related
  industries are sometimes described as being in the same broad economic sector.
  The values of stocks of many different companies in a market sector may be
  similarly affected by particular economic or market events. Although the
  Fund's principal investment strategies do not involve focusing on any
  particular sector, at times Columbia WAM's asset management strategy may cause
  the Fund to invest a large portion of its assets in a particular sector.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- how each Fund's average annual total returns compare to recognized measures of
  market performance shown in the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class R2* and Class R5* shares of Seligman Global
Smaller Companies Fund. The second table shows total returns from hypothetical
investments in Class A, Class B and Class C shares of RiverSource Partners
International Small Cap Fund. Inception date for Class R2 and Class R5 is
expected to be in the first quarter of 2010 and therefore performance
information for these classes is not shown. These returns are compared to the
indexes shown for the same periods. For purposes of the performance calculation
in the table we assumed:

 *  Prior to June 13, 2009, Class R2 shares were known as Class R shares and
    Class R5 shares were known as Class I shares.

- the maximum sales charge of 5.75% for Class A shares;

- sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B and Class C;

- no sales charge for Class R2 and Class R5 shares; and

- with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.


                                       61



AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

The Standard & Poor's/Citigroup Broad Market Less Than US $2 Billion Index (the
"S&P/Citigroup Index"), an unmanaged benchmark, represents the entire universe
of institutionally investable securities with total available market
capitalization of at least the local equivalent of US $100 million and not more
than US $2 billion.

The Lipper Global Small/Mid-Cap Funds Index (the Lipper Index) includes the 10
largest global small and mid-cap funds tracked by Lipper Inc. The index's
returns include net reinvested dividends.

The Lipper Global Small/Mid-Cap Funds Average (the Lipper Average) excludes the
effect of sales-related fees (but includes operating expenses), sales charges
and taxes. The Lipper Average measures the performance of mutual funds that, by
portfolio practice, invest at least 75% of their equity assets in companies both
inside and outside of the US with market capitalizations (on a three-year
weighted basis) below Lipper's global large-cap floor.

Prior to Jan. 1, 2003, Seligman (the predecessor investment manager) employed
subadvisers that were responsible for providing certain portfolio management
services with respect to the investments of the Fund. From Jan. 1, 2003 until
Sept. 15, 2003, the assets of the Fund were managed exclusively by Seligman.
Since September 15, 2003, Wellington Management Company, LLP has been employed
as subadviser to provide portfolio management services for the Fund. From June
2004 to April 2006, Wellington Management Company, LLP delegated a portion of
its portfolio management responsibilities in respect of the Fund to its
affiliate, Wellington Management International, Ltd.

Investors cannot invest directly in an average or an index.

For Seligman Global Smaller Companies Fund, on Nov. 1, 2009, the Lipper Index
replaced the Lipper Average as the Fund's secondary benchmark. The Lipper
Average includes all funds categorized by Lipper within the broad universe of
funds in the Lipper Average, whereas the Lipper Index includes only a select
peer group from the Lipper Average, as described above. This change was made to
bring the selection of the Seligman Fund secondary benchmarks in line with the
practice of the RiverSource Family of Funds, which would permit a common
shareholder experience and provide a more focused peer group for performance
comparison purposes. Information on both the Lipper Index and the Lipper Average
will be included for a one-year transition period. Thereafter, only the Lipper
Index will be included.

The S&P Global ex-U.S. SmallCap Index, an unmanaged benchmark, measures the
small stock component of the S&P Global ex-U.S. Broad Market. The benchmark
consists of the bottom 15% of float-adjusted market capitalization stocks within
developed and emerging markets globally (excluding the U.S.). The index reflects
reinvestment of all distributions and changes in market prices.

The S&P Global ex-U.S. Under USD2 Billion Index, an unmanaged market
capitalization weighted benchmark, measures the small stock component of the
Salomon Smith Barney Global Equity Index, which includes developed and emerging
market countries globally excluding the U.S. Within each country, those stocks
falling under a two billion dollar market cap of the available market capital in
each country form the universe. The index reflects reinvestment of all
distributions and changes in market prices.

The Lipper International Small-Cap Funds Index includes the 30 largest
international small-cap funds tracked by Lipper Inc. The index's returns include
net reinvested dividends. The Fund's performance is currently measured against
this index for purposes of determining the performance incentive adjustment.

On Aug. 10, 2009, the S&P Global ex-U.S. SmallCap Index replaced S&P Global ex-
U.S. Under USD2 Billion Index as the Fund's primary benchmark. The investment
manager made this recommendation to the Fund's Board because the new index more
closely aligns to the Fund's investment strategy. Information on both indexes
will be included for a one-year transition period. In the future, however, only
the S&P Global ex-U.S. SmallCap Index will be included.

Investors cannot invest directly in an index.

PROPOSAL 6. REORGANIZATION OF RIVERSOURCE TAX-EXEMPT MONEY MARKET FUND INTO
RIVERSOURCE GOVERNMENT MONEY MARKET FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- Have RiverSource Investments as an investment manager.

- Have the same policies for buying and selling shares and the same exchange
  rights.

- Have the same distribution policies.

- Offer shares of capital stock. The Buying Fund offers multiple classes of
  shares, whereas the Selling Fund issues one class of shares. The Selling
  Fund's shares are proposed to be merged into Class A shares of the Buying
  Fund. The Buying Fund additionally offers Classes B, C, R2 and R5.

- Are structured as an open-end management investment company. The Buying Fund
  is a Maryland corporation, whereas the Selling Fund is a series of a Minnesota
  corporation. Please see Exhibit D to this proxy statement/prospectus for more
  information regarding the differences between the rights of shareholders of
  the Buying Fund and shareholders of the Selling Fund.

COMPARISON OF INVESTMENT OBJECTIVES

Both Funds are money market funds that seek to provide current income and
liquidity while seeking to maintain a stable net asset value of $1.00 per share.
The Selling Fund, however, differs from the Buying Fund in that the Selling Fund
seeks to provide current income exempt from federal income tax. Because any
investment involves risk, there is no assurance these objectives can be
achieved. Only shareholders can change the Fund's objective.

The investment objectives for the Funds are as follows:

          SELLING FUND: RiverSource Tax-Exempt Money Market Fund seeks to
                        provide shareholders with as high a level of current
                        income exempt from federal income tax as is consistent
                        with liquidity and stability of principal.

          BUYING FUND: RiverSource Government Money Market Fund seeks to
                       preserve capital and to maximize liquidity and current
                       income.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests primarily in U.S. dollar-denominated money market instruments
meeting certain maturity and quality standards. While the Selling Fund invests
primarily in instruments exempt from U.S. federal income tax and the alternative
minimum tax ("AMT"), the Buying Fund invests primarily in money market
securities that are issued or guaranteed by the U.S. government, its agencies or
instrumentalities. Both the Selling and the Buying Fund limit their investments
to securities that present minimal credit risk. The Buying Fund currently limits
its investments to U.S. government securities and securities that are rated in
the top category by Moody's and S&P 500. The Selling Fund may invest up to 25%
of its net assets in securities of issuers located in the same state or region
or in industrial revenue bonds, while the Buying Fund has no similar
restrictions (given its investment focus on U.S. government securities).


                                       65



Detailed strategies for the Selling Fund and the Buying Fund are set forth
below:

--------------------------------------------------------------------------------------------
</Table>


In addition to the principal investment strategies set forth above, both Funds
also have the following principal investment strategies:

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- The issuer's credit rating declines or the investment manager expects a
  decline (the Fund, in certain cases, may continue to own securities that are
  down-graded until the investment manager believes it is advantageous to sell).

- Political, economic, or other events could affect the issuer's performance.

- The investment manager identifies a more attractive opportunity.

- The issuer or the security continues to meet the other standards described
  above.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. The Selling Fund and the
Buying Fund have similar fundamental policies with the exception of the 80%
policy of the Selling Fund in comparison to the industry concentration policy of
the Buying Fund. The Selling Fund will not, under normal market conditions,
invest less than 80% of its net assets in bonds and other debt securities issued
by or on behalf of state or local governmental units whose interest is exempt
from federal income tax. The Buying Fund reserves the right to concentrate
investments in money market instruments issued by the U.S. government or its
agencies or instrumentalities or banks or bank holding companies. This 80%
policy of the Buying Fund is non-fundamental. For purposes of this discussion, a
"fundamental" investment policy is one that may not be changed without a
shareholder vote. The Funds' fundamental investment policies are set forth
below:

COMPARISON OF NONFUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies (policies that may be changed without a
shareholder vote) of the Buying Fund. In addition to the nonfundamental policies
outlined in the Comparison of Principal Investment Strategies, both Funds are
also subject to the following additional nonfundamental policy:

- No more than 10% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund generally are similar
because both Funds are money market funds, although the Selling Fund invests
primarily in municipal obligations, whereas the Buying Fund invests primarily in
securities of the U.S. government, its agencies and instrumentalities. The
actual risks of investing in each Fund depend on the securities held in each
Fund's portfolio and on market conditions, both of which change over time. Both
Funds are subject to the principal investment risks described below.

     An investment in the Fund is not a deposit in a bank and is not insured or
     guaranteed by the Federal Deposit Insurance Corporation or any other
     government agency. Although the Fund seeks to preserve the value of your
     investment at $1.00 per share, it is possible to lose money by investing in
     the Fund.

     The Fund is actively managed and its performance therefore will reflect in
     part the ability of the portfolio manager to select securities and to make
     investment decisions that are suited to achieving the Fund's investment
     objective. Due to its active management, the Fund could underperform other
     mutual funds with similar investment objectives.

     Yield and total return of the Fund will fluctuate with fluctuations in the
     yields of the securities held by the Fund. In periods of declining interest
     rates, the yields of the securities held by the Fund will tend to be
     somewhat higher than prevailing market rates, and in periods of rising
     interest rates, the yields of securities held by the Fund will tend to be
     lower than market rates. Additionally, when interest rates are falling, the
     inflow of new money to the Fund from sales of its shares will likely be
     invested in securities producing lower yields than the balance of the
     Fund's assets, reducing the current yield of the Fund. In periods of rising
     interest rates, the opposite may be true.

     In addition to the risks described above, the Buying Fund is subject to the
     additional principal investment risks set forth below. While these
     additional risks may also be risks of the Selling Fund, they are not stated
     as principal investment risks of the Selling Fund. For more information
     regarding the Selling Fund's principal investment risks, see "Principal
     Risks" in the Selling Fund's prospectus.

     Repurchase agreements in which the Fund may invest could involve certain
     risks in the event of default by the seller, including possible delays and
     expenses in liquidating the securities underlying the agreement, decline in
     the value of the underlying securities and loss of interest.

     Investments in foreign banks and foreign branches of U.S. banks involve
     certain risks not generally associated with investments in U.S. banks.
     While U.S. banks and U.S. branches of foreign banks are required to
     maintain certain reserves and are subject to other regulations, these
     requirements and regulations may not apply to foreign banks or foreign
     branches of U.S. banks. Investments in foreign banks and foreign branches
     may also be subject to other risks, including political or economic
     developments, the seizure or nationalization of foreign deposits and the
     establishments of exchange controls or other restrictions.

     In addition to the risks described above, the Selling Fund is subject to
     the additional principal investment risks set forth below. While these
     additional risks may also be risks of the Buying Fund, they are not stated
     as principal investment risks of the Buying Fund. For more information
     regarding the Buying Fund's principal investment risks, see "Principal
     Risks" in the Buying Fund's prospectus.

CREDIT RISK. Credit risk is the risk that the issuer of a security, or the
counterparty to a contract, will default or otherwise become unable or unwilling
to honor a financial obligation, such as payments due on a bond or a note. If
the Fund purchases unrated securities, or if the rating of a security is reduced
after purchase, the Fund will depend on the investment manager's analysis of
credit risk more heavily than usual.

MUNICIPAL SECURITIES RISK. The value of a municipal security may be affected by
legislative or administrative actions as well as by the economies of the region
where the issuer of the municipal security is located. For example, a
significant restructuring of federal income tax rates could cause municipal
security prices to fall. Lower income tax rates could reduce the advantage of
owning municipal securities.

REINVESTMENT RISK. Reinvestment risk is the risk that the Fund will not be able
to reinvest income or principal at the same rate it currently is earning.

PERFORMANCE

The following bar charts and table provide some illustration of the risks of
investing in the Funds by showing the variability of performance.

Both the bar chart and the table assume that all distributions have been
reinvested. How a Fund has performed in the past does not indicate how the Fund
will perform in the future. Performance reflects any fee waivers/expense caps in
effect for the periods reported. In the absence of such fee waivers/expense
caps, performance would have been lower.

Bar Charts. The bar chart shows how a Fund's performance has varied for each
full calendar year. For purposes of comparison, the single class of shares of
RiverSource Tax-Exempt Money Market Fund is referred to as Class A shares.

Table. The first line of the table shows total returns from a hypothetical
investment in shares of RiverSource Tax-Exempt Money Market Fund. For purposes
of comparison, the single class of shares of RiverSource Tax-Exempt Money Market
Fund is referred to as Class A shares. The second line of the table shows total
returns from a hypothetical investment in Class A shares of RiverSource
Government Money Market Fund. For purposes of the performance calculation in the
table we assumed no adjustments for taxes paid by an investor on the reinvested
income and capital gains.

ADDITIONAL INFORMATION ABOUT EACH REORGANIZATION

TERMS OF THE REORGANIZATIONS

The Board has approved the Agreement, the form of which is attached as Exhibit
A. The Agreement provides for Reorganizations on the following terms:

- Each Reorganization is expected to occur before the end of the second quarter
  of 2010, pending shareholder approval, receipt of any necessary regulatory
  approvals and satisfaction of any other conditions to closing. However,
  following shareholder approval, each Reorganization may happen at any time
  agreed to by the applicable Selling Fund and the corresponding Buying Fund.

- Each Selling Fund will transfer all of its assets to the corresponding Buying
  Fund and, in exchange, the corresponding Buying Fund will assume all the
  Selling Fund's liabilities and will issue to the Selling Fund, as applicable,
  Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4 and/or Class
  R5 shares with an aggregate net asset value on the business day immediately
  preceding the closing of the Reorganization equal to the value of the assets
  that it receives from the Selling Fund, less the liabilities assumed by the
  corresponding Buying Fund in the transaction. The Reorganization Shares will
  immediately be distributed to Selling Fund shareholders in proportion to their
  holdings of shares of the Selling Fund. As a result, shareholders of the
  Selling Fund will become, as applicable, Class A, Class B, Class C, Class I,
  Class R2, Class R3, Class R4 and/or Class R5 shareholders of the corresponding
  Buying Fund.

- No Selling Fund and no shareholders of any Selling Fund will pay any sales
  charge in connection with its Reorganization.

- The net asset value of each Selling Fund and the corresponding Buying Fund
  will be computed as of 3:00 p.m., Central time, on the business day
  immediately preceding the closing date of the applicable Reorganization.

- After its Reorganization, each Selling Fund will be dissolved.

CONDITIONS TO CLOSING EACH REORGANIZATION

The completion of each Reorganization is subject to certain conditions described
in the Agreement, including:

- The Selling Fund will have declared and paid a dividend that will distribute
  all of the Selling Fund's net investment income and net capital gains, if any,
  to the shareholders of the Selling Fund for taxable years ending on or prior
  to the closing date of the Reorganization.

- The Funds will have received any approvals, consents or exemptions from the
  SEC or any other regulatory body necessary to carry out the Reorganization.

- A registration statement on Form N-14 relating to the Reorganization will have
  been filed with the SEC and declared effective.

- The shareholders of the Selling Fund will have approved the Agreement by the
  requisite vote necessary.

- The Selling Fund will have received an opinion of tax counsel to the effect
  that, although, with respect to the Reorganizations of RiverSource Partners
  Aggressive Growth Fund, RiverSource Partners Select Value Fund, RiverSource
  Partners Small Cap Equity Fund, RiverSource Partners Small Cap Growth Fund and
  Seligman Global Smaller Companies Fund, the matter is not free from doubt, the
  shareholders of the Selling Fund will not recognize gain or loss for federal
  income tax purposes upon the exchange of their Selling Fund shares for the
  corresponding Buying Fund shares in connection with the Reorganization.

TERMINATION OF THE AGREEMENT

The Agreement and the transactions contemplated by it may be terminated and
abandoned with respect to any Reorganization by resolution of the Board at any
time prior to closing date thereof. In the event of a termination, RiverSource
Investments will bear all costs associated with the Reorganization.

TAX STATUS OF THE REORGANIZATIONS

Each Reorganization is intended to qualify for federal income tax purposes as a
tax-free reorganization under section 368(a) of the Internal Revenue Code of
1986, as amended (the "Code"). As a condition to the closing of each
Reorganization, each Selling Fund and each Buying Fund will receive an opinion
from Ropes & Gray LLP to the effect that, although, with respect to the
Reorganizations of RiverSource Partners Aggressive Growth Fund into RiverSource
Mid Cap Growth Fund, RiverSource Partners Select Value Fund into RiverSource Mid
Cap Value Fund, RiverSource Partners Small Cap Equity Fund into Seligman
Smaller-Cap Value Fund, RiverSource Partners Small Cap Growth Fund into Seligman
Frontier Fund and Seligman Global Smaller Companies Fund into RiverSource
Partners International Small Cap Fund, the matter is not free from doubt, on

  Fund to Selling Fund shareholders in liquidation.

  as applicable, of the Selling Fund exchanged therefor.

- Under Section 1223(1) of the Code, the holding period for the Class A, Class
  B, Class C, Class I, Class R2, Class R3, Class R4 and Class R5 shares, as
  applicable, of the Buying Fund that a Selling Fund shareholder receives in the
  Reorganization will include the period for which he or she held the Class A,
  Class B, Class C, Class I, Class R2, Class R3, Class R4 and Class R5 shares,
  as applicable, of the Selling Fund exchanged therefor, provided that on the
  date of the exchange he or she held such Selling Fund shares as capital
  assets.

  for the issuance of the Buying Fund's Class A, Class B, Class C, Class I,
  Class R2, Class R3, Class R4 and Class R5 shares, as applicable, to the
  Selling Fund and the assumption of all of the Selling Fund's liabilities by
  the Buying Fund.

- Under Section 362(b) of the Code, the Buying Fund's tax basis in the assets
  received from the Selling Fund will be the same as the Selling Fund's tax
  basis in those assets immediately prior to the transfer.

- Under Section 1223(2) of the Code, the Buying Fund's holding periods in the
  assets received from the Selling Fund will include the Selling Fund's holding
  periods in such assets.

- The Buying Fund will succeed to and take into account the items of the Selling
  Fund described in Section 381(c) of the Code, subject to the conditions and
  limitations specified in Sections 381, 382, 383 and 384 of the Code and the
  regulations thereunder.

Ropes & Gray LLP will express no view with respect to the effect of a
Reorganization on any transferred asset as to which any unrealized gain or loss
is required to be recognized under federal income tax principles (i) at the end
of a taxable year or upon the termination thereof, or (ii) upon the transfer of
such asset regardless of whether such a transfer would otherwise be a non-
taxable transaction.

Each opinion will be based on certain factual certifications made by the
officers of the Selling Fund and the Buying Fund and will also be based on
customary assumptions. With respect to the Reorganizations listed above, each
opinion will note and distinguish certain published precedent. It is possible
that the Internal Revenue Service (the "IRS") could disagree with Ropes & Gray
LLP's opinion.

Opinions of counsel are not binding upon the IRS or the courts. If a
Reorganization were consummated but did not qualify as a tax-free reorganization
under the Code, a shareholder of the Selling Fund would recognize a taxable gain
or loss equal to the difference between his or her tax basis in his or her
Selling Fund shares and the fair market value of the shares of the Buying Fund
he or she received. Shareholders of a Selling Fund should consult their tax
advisors regarding the effect, if any, of the Reorganization in light of their
individual circumstances.

In the case of RiverSource Partners Small Cap Equity Fund, RiverSource Partners
Small Cap Growth Fund, RiverSource Partners Select Value Fund and RiverSource
Partners Aggressive Growth Fund, portfolio manager substitutions independent of
the Reorganizations have occurred and have resulted in substantial portfolio
turnover. An additional portion of or all of the portfolio assets of each
Selling Fund may also be sold in connection with its Reorganization. The actual
tax impact of such sales depends on the difference between the price at which
such portfolio assets are sold and the Selling Fund's tax basis in

                                       73



such assets. Any net capital gains recognized in these sales will be distributed
to shareholders as capital gain dividends (to the extent of net realized long-
term capital gains over net realized short-term capital losses) and/or ordinary
dividends (to the extent of net realized short-term capital gains over net
realized long-term capital losses) during or with respect to the year of sale,
and such distributions will be taxable to shareholders. Each Reorganization will
end the tax year of the applicable Selling Fund, and will therefore accelerate
any distributions to shareholders from the Selling Fund for its short tax year
ending on the date of the Reorganization. Prior to the closing of each
Reorganization, the Selling Fund will, and the Buying Fund may, declare a
distribution to shareholders, which, together with all previous distributions,
will have the effect of distributing to shareholders all of its investment
company taxable income (computed without regard to the deduction for dividends
paid), net tax-exempt income, if any, and net realized capital gains, if any,
through the closing of the Reorganization, including any undistributed income or
gains from the immediately preceding year. These distributions will be taxable
to shareholders except to the extent of any exempt-interest dividends, and such
distributions by a Selling Fund will include any capital gains resulting from
portfolio turnover prior to the Reorganization. If a shareholder holds shares of
either Fund in a non-taxable account, distributions with respect to those shares
will not be taxable to the shareholder if the amount distributed remains in the
non-taxable account.

A Fund's ability to carry forward capital losses and to use them to offset
future gains may be limited as a result of the Reorganization. First, a Fund's
"pre-acquisition losses" (including capital loss carryforwards, net current-year
capital losses, and unrealized losses that exceed certain thresholds) may become
unavailable to offset gains of the combined Fund. Second, one Fund's pre-
acquisition losses cannot be used to offset unrealized gains in another Fund
that are "built in" at the time of the Reorganization and that exceed certain
thresholds ("non-de minimis built-in gains") for five tax years. Third, a
Selling Fund's loss carryforwards, as limited under the previous two rules, are
permitted to offset only that portion of the gains of the Buying Fund for the
taxable year of the Reorganization that is equal to the portion of the Buying
Fund's taxable year that follows the date of the Reorganization (prorated
according to number of days). Therefore, in certain circumstances, certain
shareholders of a Fund may pay taxes sooner, or pay more taxes, than they would
have had a Reorganization not occurred.

In addition, the combined Fund resulting from each Reorganization will have tax
attributes that reflect a blending of the tax attributes of the Funds at the
time of the Reorganization (including as affected by the rules set forth above).
Therefore, the shareholders of the Selling Fund will in each case receive a
proportionate share of any "built-in" (unrealized) gains in the Buying Fund's
assets, as well as any taxable gains realized by the Buying Fund but not
distributed to its shareholders prior to the Reorganization, when such gains are
eventually distributed. As a result, shareholders of a Selling Fund may receive
a greater amount of taxable distributions than they would have had the
Reorganization not occurred. And any pre-acquisition losses of the Selling Fund
(whether realized or unrealized) remaining after the operation of the limitation
rules described above will become available to offset capital gains realized by
the combined Fund after the Reorganization and thus may reduce subsequent
capital gain distributions to a broader group of shareholders than would have
been the case absent such Reorganization, such that the benefit of those losses
to Selling Fund shareholders may be further reduced relative to what the benefit
would have been had the Reorganization not occurred.

The amount of realized and unrealized gains and losses of each Fund, as well as
the size of each Fund, at the time of its Reorganization will determine the
extent to which the combining Funds' respective losses, both realized and
unrealized, will be available to reduce gains realized by the combined Fund
following the Reorganization, and consequently the extent to which the combined
Fund may be required to distribute gains to its shareholders earlier than would
have been the case absent the Reorganization. Thus the impact of the rules
described above will depend on factors that are currently unknown, such that
this impact cannot be calculated precisely prior to the Reorganization. The
following paragraph provides a brief summary of the tax impacts, due to the
above-described rules and consequences relating to the combination of the tax
attributes of the two funds, of the Reorganizations had they occurred on
September 23, 2009. As noted above, the tax impact of a Reorganization depends
on each Fund's relative tax situation at the time of the Reorganization, which
will be different than the tax situation on September 23, 2009, such that the
tax impacts described herein may not pertain at the time of the Reorganization.
Further due to the significant portfolio turnover of certain of the Selling
Funds resulting from portfolio manager substitutions made independent of the
Reorganizations, and volatility in the marketplace, the actual tax impact of the
Reorganizations could differ substantially from those described below.

Proposal 1: Reorganization of RiverSource Partners Aggressive Growth Fund into
RiverSource Mid Cap Growth Fund: As of September 23, 2009, RiverSource Partners
Aggressive Growth Fund (the "Selling Fund") had net realized losses (including
capital loss carryforwards) equal to approximately 149.0% of net assets (which
included a capital loss carryforward equal to about 90% of net assets that was
due to expire at the end of the Fund's current taxable year) and RiverSource Mid
Cap Growth Fund ("Buying Fund") had net realized losses (including capital loss
carryforwards) equal to approximately 10.5% of net assets, and Selling Fund and
Buying Fund had net unrealized gains equal to approximately 19.4% and 9.6% of
net assets, respectively. If the Reorganization had occurred on September 23,
2009, the loss limitation rules would have substantially limited the combined
Fund's ability to use Selling Fund losses to offset gains recognized by the
combined Fund, potentially resulting in a significantly greater amount of
taxable distributions, and therefore a greater tax cost, to Selling Fund

                                       74



shareholders than if the Reorganization had not occurred. In addition, to the
extent Selling Fund's losses were used to offset gains of the combined Fund, the
tax benefit would have been spread over a larger group of shareholders than if
the Reorganization had not occurred, resulting in a potential tax cost to
Selling Fund shareholders.

Subsequent to September 23, 2009, Selling Fund experienced significant portfolio
turnover. The recognition of gain or loss resulting from such portfolio turnover
could increase the potential tax cost of the Reorganization to Selling Fund
shareholders relative to the costs described above.

Proposal 2: Reorganization of RiverSource Partners Select Value Fund into
RiverSource Mid Cap Value Fund: As of September 23, 2009, RiverSource Partners
Select Value Fund (the "Selling Fund") had net realized losses (including
capital loss carryforwards) equal to approximately 40.0% of its net assets and
unrealized gains equal to approximately 13.1% of its net assets. RiverSource Mid
Cap Value Fund ("Buying Fund") had no capital loss carryforwards, net realized
losses equal to approximately 28.2% of its nets assets and unrealized losses
equal to approximately 3.1% of its net assets. If the Reorganization had
occurred on September 23, 2009, the loss limitation rules would not have
significantly affected the combined Fund's ability to use Selling Fund losses to
offset gains recognized by the combined Fund. Furthermore, Selling Fund
shareholders might have benefited from the use of Buying Fund's losses to offset
gains.

Subsequent to September 23, 2009, Selling Fund experienced significant portfolio
turnover. The recognition of gain or loss resulting from such portfolio turnover
could increase the potential tax cost of the Reorganization to Selling Fund
shareholders relative to the costs described above.

Proposal 3: Reorganization of RiverSource Partners Small Cap Equity Fund into
Seligman Smaller-Cap Value Fund: As of September 23, 2009, RiverSource Partners
Small Cap Equity Fund (the "Selling Fund") and Seligman Smaller-Cap Value Fund
("Buying Fund") had net realized losses (including capital loss carryforwards)
equal to approximately 50.2% and 50.4% of net assets, respectively, and net
unrealized gains equal to 6.6% and 25.0% of net assets, respectively. If the
Reorganization had occurred on September 23, 2009, the loss limitation rules
would have applied to Selling Fund's losses, and also to certain of Buying
Fund's losses (namely, the pre-acquisition losses of RiverSource Small Cap
Advantage Fund on its acquisition by Buying Fund on September 14, 2009, which as
of September 23, 2009 were equal to approximately 45.0% of Buying Fund's net
assets). The limitation on Selling Fund's losses would have resulted in a
potential tax cost to Selling Fund shareholders. In addition, Selling Fund
shareholders would have shared in Buying Fund's unrealized gains, and the
subsequent realization of those gains might have further increased the tax cost
to Selling Fund shareholders.

Subsequent to September 23, 2009, Selling Fund experienced significant portfolio
turnover. The recognition of gain or loss resulting from such portfolio turnover
could increase the potential tax cost of the Reorganization to Selling Fund
shareholders relative to the costs described above.

Proposal 4: Reorganization of RiverSource Partners Small Cap Growth Fund into
Seligman Frontier Fund: As of September 23, 2009, RiverSource Partners Small Cap
Growth Fund (the "Selling Fund") had net realized losses (including capital loss
carryforwards) equal to approximately 38.3% of its net assets and unrealized
gains equal to approximately 8.1% of its net assets. Seligman Frontier Fund
("Buying Fund") had net realized losses (including capital loss carryforwards)
equal to approximately 23.3% of its net assets and unrealized losses equal to
approximately 0.4% of its net assets. If the Reorganization had occurred on
September 23, 2009, the loss limitation rules would have applied to Buying
Fund's losses rather than Selling Fund's losses. Therefore, the ability to use
Selling Fund's losses to offset gains recognized by the combined Fund would not
have been limited (except as required under the proration rule for the taxable
year of the Reorganization described above). However, because Selling Fund's
losses would have been available to reduce subsequent capital gain distributions
to shareholders of the combined Fund, the tax benefit of such losses would have
been spread over a larger group of shareholders than if the Reorganization had
not occurred, resulting in a potential tax cost to Selling Fund shareholders.

Subsequent to September 23, 2009, Selling Fund experienced significant portfolio
turnover. The recognition of gain or loss resulting from such portfolio turnover
could increase the potential tax cost of the Reorganization to Selling Fund
shareholders relative to the costs described above.

Proposal 5: Reorganization of Seligman Global Smaller Companies Fund into
RiverSource Partners International Small Cap Fund: As of September 23, 2009,
Seligman Global Smaller Companies Fund (the "Selling Fund") and RiverSource
Partners International Small Cap Fund ("Buying Fund") had net realized losses
(including capital loss carryforwards) equal to approximately 94.9% and 57.2% of
net assets, respectively, and net unrealized gains equal to 11.5% and 11.6% of
net assets, respectively. If the Reorganization had occurred on September 23,
2009, a limitation would have been imposed on the use of Buying Fund's losses,
but the ability to use Selling Fund's losses to offset gains realized by the
combined Fund would not have been limited (except as required under the
proration rule for the taxable year of the Reorganization described above). At
the same time, however, Selling Fund's losses would have been available to
reduce subsequent capital gain distributions of the combined Fund, spreading the
tax benefit of such losses over a larger group of shareholders than if the
Reorganization had not occurred, resulting in a potential tax cost to Selling
Fund shareholders.


                                       75



Subsequent to September 23, 2009, Selling Fund expects to experience significant
portfolio turnover in connection with the Reorganization. The recognition of
gain or loss resulting from such portfolio turnover could increase the potential
tax cost of the Reorganization to Selling Fund shareholders relative to the
costs described above.

Proposal 6: Reorganization of RiverSource Tax-Exempt Money Market Fund into
RiverSource Government Money Market Fund: As of September 23, 2009, RiverSource
Tax-Exempt Money Market Fund (the "Selling Fund") had negligible capital loss
carryforwards and realized gains and no unrealized gains or losses. RiverSource
Government Money Market Fund ("Buying Fund") had no capital loss carryforwards,
no realized gains or losses, and no unrealized gains or losses. Because neither
Fund had a noticeable amount of capital gains or losses (as is common for money
market funds due to the nature of their investments), had the Reorganization
occurred on September 23, 2009, neither the loss limitation rules nor the
blending of tax attributes of the Funds would have had an impact on the amount
of distributions to Selling Fund shareholders as compared to if no
Reorganization had occurred.

The tax principles described above are not expected to change. However, their
application and, at a minimum, the specific percentages noted above will change
prior to each Reorganization because of market developments and volatility in
the marketplace, any pre-Reorganization realignments or other sales of portfolio
securities that might occur or that already have occurred, and shareholder
activity in the Funds, among other changes.

Shareholders of a Selling Fund should consult their tax advisors regarding the
effect, if any, of the Reorganization in light of their individual
circumstances. Because the foregoing discussion relates only to the federal
income tax consequences of the Reorganizations shareholders of a Selling Fund
should also consult their tax advisors as to the state, local and foreign tax
consequences, if any, of the Reorganizations.

REASONS FOR THE PROPOSED REORGANIZATIONS AND BOARD DELIBERATIONS

The Board believes that each proposed Reorganization will be advantageous to
Selling Fund and Buying Fund shareholders based on its consideration of the
following matters:

- TERMS AND CONDITIONS OF THE REORGANIZATION. The Board considered the terms and
  conditions of each Reorganization as described in the previous paragraphs.

- TAX CONSEQUENCES. [The Board considered the tax-free nature of each
  Reorganization. The Board also considered the relative tax situations of each
  Fund and the resulting tax impact of the Reorganization to Selling Fund
  shareholders, and noted that the benefits of each Reorganization should
  outweigh any resulting tax cost to shareholders. With respect to the proposed
  Reorganization of RiverSource Tax-Exempt Money Market Fund into RiverSource
  Government Money Market Fund, the Board considered, in particular, the
  potential impact on shareholders of the Selling Fund once they become Buying
  Fund shareholders who can expect to receive distributions from the Buying Fund
  that are taxable for U.S. federal income tax purposes. As a result, the Board
  reviewed the historical tax equivalent yields of both Funds, noting, in
  particular, that each Fund currently maintains a similar slight positive
  yield, which is supported by voluntary expense caps (noted below under
  "Expense Ratios"). With regard to the tax-free nature of the Reorganization,
  the Board considered each Fund's relative performance, observing that, as a
  condition of the tax opinion they were receiving, the combined Fund would be
  required to continue to hold securities of the Selling Fund and, as a result,
  the Buying Fund, a U.S. government Fund, would have a portion of its portfolio
  consist of municipal securities for a short period of time (e.g., until such
  securities matured). Nevertheless, the following mitigating factors were
  pointed out, among others: (i) the municipal securities to be transferred are
  expected to be rated in the highest credit rating category, albeit not U.S.
  government credit quality; (ii) the transferred holdings would likely mature
  between 1 and 60 days thereby reducing the impact of any incremental credit
  risk (the transferred holdings would represent the average maturity of the
  Selling Fund's portfolio at the time of merger, providing that such average
  maturity hadn't changed significantly in anticipation of the merger); (iii)
  the tax equivalent yields on the transferred securities are expected to exceed
  the Buying Fund's then-current portfolio yield; and (iv) the expense
  advantages to the Buying Fund that would result from the Reorganization (noted
  below under "Expense Ratios"). The Boards also accorded weight to the other
  benefits of the Reorganization described below under "Performance and Other
  Factors."

 With respect to the Reorganizations of RiverSource Partners Aggressive Growth
 Fund into RiverSource Mid Cap Growth Fund and RiverSource Partners Small Cap
 Equity Fund into Seligman Smaller-Cap Value Fund, the Board considered, in
 particular, the potential tax costs arising from the limitation imposed
 following the Reorganization on the capital loss carryforwards of each of these
 Selling Funds (which, in the case of RiverSource Partners Aggressive Growth
 Fund, are significant). As a result, as described in more detail in the section
 entitled "Tax Status of the Reorganizations," it is possible that the
 Reorganization will have the effect of accelerating income taxes (by virtue of
 distributing additional taxable income) to taxable shareholders of these Funds.
 The Board observed, however, the following mitigating factors: (i) these
 Selling Funds, as a result of the Reorganization, are expected to experience
 expense savings which, over the long term, should outweigh the tax cost to
 shareholders; and (ii) a majority of these Selling Funds' shareholders are
 represented by "qualified"

                                       76






 accounts that would experience no tax cost as a result of the limitation on
 capital loss carryforwards. The Board also accorded weight to RiverSource
 Investments' agreement to further cap the expenses of the combined Funds (as
 discussed below under "Expense Ratios"). The Boards also accorded weight to the
 other benefits of each Reorganization described below under "Performance and
 Other Factors."]

- CONTINUITY OF INVESTMENT. The Board took into account the fact that each
  Selling Fund and the corresponding Buying Fund have similar or identical
  investment objectives and, except as noted below and as discussed in more
  detail under each proposal, similar investment strategies:

 Proposal 1: Reorganization of RiverSource Partners Aggressive Growth Fund into
 RiverSource Mid Cap Growth Fund: The Board considered that RiverSource Partners
 Aggressive Growth Fund's investment objective of providing shareholders with
 long-term capital growth is substantially similar to that of RiverSource Mid
 Cap Growth Fund, which is to provide shareholders with growth of capital,
 because each Fund is intended for long-term investors. The Board also took into
 account the similarity in investment strategies in that both Funds invest
 primarily in equity securities of medium-sized companies whose market
 capitalization at the time of purchase falls within the range of the Russell
 Midcap Growth Index. The Board considered that RiverSource Mid Cap Growth Fund
 is designed to invest at least 80% of its net assets in equity securities of
 medium-sized companies, whereas RiverSource Partners Aggressive Growth Fund has
 no minimum percentage. The Board also took into account that both Funds share
 common benchmarks, the Russell Midcap Growth Index and the Lipper Mid-Cap
 Growth Funds Index. Also, the Board considered that, although both Funds have
 RiverSource Investments as an investment adviser, RiverSource Partners
 Aggressive Growth Fund had been subadvised by American Century and Turner.

 Proposal 2: Reorganization of RiverSource Partners Select Value Fund into
 RiverSource Mid Cap Value Fund: The Board considered that the Funds have an
 identical investment objective of providing shareholders with long-term growth
 of capital. The Board also took into account the similarity in investment
 strategies in that both Funds invest primarily in equity securities of medium-
 sized companies. The Board considered that RiverSource Mid Cap Value Fund
 invests at least 80% of its net assets in equity securities of medium-sized
 companies; whereas, RiverSource Partners Select Value Fund has no specified
 minimum percentage. The Board considered that both Funds share common
 benchmarks, the Russell Mid Cap Value Index and the Lipper Mid-Cap Value Funds
 Index. Also, the Board considered that, although both Funds currently have
 RiverSource Investments as an investment manager, RiverSource Partners Select
 Value Fund had been subadvised by Systematic and WEDGE.

 Proposal 3: Reorganization of RiverSource Partners Small Cap Equity Fund into
 Seligman Smaller-Cap Value Fund: The Board considered that the Funds have an
 identical investment objective of providing shareholders with long-term capital
 appreciation. The Board also took into account the similarity in investment
 strategies in that both Funds invest in value stocks of small market companies.
 The Board considered that RiverSource Partners Small Cap Equity Fund defines
 small market companies as those that have a market capitalization not greater
 than that of the largest company in the Russell 2000 Index or the S&P SmallCap
 600 Index at the time of investment, whereas Seligman Smaller-Cap Value Fund
 defines small market companies as those with a market capitalization of $3
 billion or less at the time of investment.

 Proposal 4: Reorganization of RiverSource Partners Small Cap Growth Fund into
 Seligman Frontier Fund: The Board considered that RiverSource Partners Small
 Cap Growth Fund's investment objective of providing shareholders with long-term
 capital growth is substantially similar to that of Seligman Frontier Fund,
 which is to provide shareholders with growth of capital. The Board also took
 into account the similarity in investment strategies in that both Funds invest
 primarily in equity securities of small U.S. companies. The Board observed that
 RiverSource Partners Small Cap Growth Fund invests at least 80% of its net
 assets in small cap companies; whereas Seligman Frontier Fund invests at least
 65% of its net assets in small cap companies. The Board also considered that,
 although both Funds currently have RiverSource Investments as an investment
 manager, RiverSource Partners Small Cap Growth Fund had been subadvised by
 Essex Investment Management and UBS Global Asset Management.

 Proposal 5: Reorganization of Seligman Global Smaller Companies Fund into
 RiverSource Partners International Small Cap Fund: The Board considered that
 the Funds have the same investment objectives. The Board took into account
 that, although both Funds invest in equity securities of smaller non-U.S.
 companies, Seligman Global Smaller Companies Fund invests 80% in smaller U.S.
 and non-U.S. companies and may invest in companies domiciled in any country
 (although it typically invests in developed market countries); whereas,
 RiverSource Partners International Small Cap Fund invests 80% in small
 companies whose market capitalization falls within the range of capitalization
 of companies in the S&P Global ex-U.S. Small Cap Index and may invest in mature
 markets and in emerging markets. The Board considered that RiverSource Partners
 International Small Cap Fund invests substantially in non-U.S. companies while
 Seligman Global Smaller Companies Fund is only required to invest at least 40%
 of its net assets in such companies. The Board also noted that RiverSource
 Investments serves as the investment manager for each Fund and is responsible
 for the oversight of each Fund's subadviser, which provides day-to-day
 management of each Fund, and that Seligman Global Smaller Companies Fund is

                                       77






 subadvised by Wellington and RiverSource Partners International Small Cap Fund
 is subadvised by Batterymarch and Columbia WAM.

 Proposal 6: Reorganization of RiverSource Tax-Exempt Money Market Fund into
 RiverSource Government Money Market Fund: The Board considered that both Funds
 have a similar investment objective in that they both seek maximum income
 consistent with preserving capital and liquidity. However, the Board also
 considered the key difference that RiverSource Tax-Exempt Money Market Fund, as
 part of its investment objective, must seek high current income exempt from
 federal income tax; whereas, the Buying Fund has no such tax-exempt aspect in
 its objective (or strategy). In this regard, the Board also took into account
 that RiverSource Tax-Exempt Money Market Fund invests substantially in money
 market municipal securities (exempt from federal income tax and the alternative
 minimum tax); whereas, RiverSource Government Money Market Fund invests in
 money market securities that are issued or guaranteed by the U.S. government,
 its agencies or instrumentalities. In this regard, the Board reviewed the
 resulting tax implications for Selling Fund shareholders (i.e., becoming
 shareholders of a Fund that generates income distributions subject to federal
 income tax) that are discussed above under "Tax Consequences," noting its
 analysis of current yields of both Funds and historical tax-equivalent yields
 (as also discussed above under "Tax Consequences"). The Board also observed
 that RiverSource Tax-Exempt Money Market Fund continues to be faced with a
 limited supply of investment opportunities in tax-exempt money market
 instruments which, together with the Fund's relatively higher gross expense
 ratios, challenges the long-term viability of the Fund.

- EXPENSE RATIOS. The Board considered the relative expenses of the Funds.
  Specifically, the Board considered that, as of the end of each Fund's most
  recent fiscal year, the net expense ratio (reflecting any fee waiver or
  expense reimbursement because of contractual expense caps) for each Selling
  Fund's Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4 and
  Class R5 shares, as applicable (before giving effect to any applicable
  performance incentive adjustment and excluding certain other fees and
  expenses), except for Seligman Global Smaller Companies Fund Class R2 and
  Class R5 shares and RiverSource Partners Select Value Fund Class A, Class B
  and Class C shares, was equal to or higher than the net expense ratio for the
  corresponding Buying Fund's class of shares (before giving effect to any
  applicable performance incentive adjustment and excluding certain other fees
  and expenses). The Board also evaluated the anticipated expense ratio impacts
  to other share classes of the Buying Funds not involved in the
  Reorganizations. The Board further noted that the level of any reduction in
  expense ratio for the Selling Funds would vary by share class. The Board also
  examined the expense impact of each Reorganization on shareholders of each
  Buying Fund and, in this regard, observed that, except as noted below, the net
  expense ratio (excluding any performance incentive adjustment) for each Buying
  Fund is expected to decrease or remain the same as a result of the relevant
  Reorganization. More particular considerations (based on analysis of Class A
  shares, unless otherwise indicated) are set forth below:

 Proposal 1: Reorganization of RiverSource Partners Aggressive Growth Fund into
 RiverSource Mid Cap Growth Fund: The Board considered that, based on most
 recent fiscal year-end data, the gross expense ratio and net expense ratio
 (reflecting the current contractual fee waiver and expense reimbursement) of
 RiverSource Partners Aggressive Growth Fund (before giving effect to any
 applicable performance incentive adjustment and excluding certain other fees
 and expenses) are the same as or higher than the gross expense ratio and net
 expense ratio of RiverSource Mid Cap Growth Fund. The Board also considered the
 commitment of the investment manager and its affiliates to waive certain fees
 and expenses for one year following the effective date of the merger based on
 the least of (i) RiverSource Mid Cap Growth Fund's expense ratio (before giving
 effect to any performance incentive adjustment) as of its fiscal year-end on
 November 30, 2009; (ii) RiverSource Mid Cap Growth Fund's expense cap
 (including the assets of both RiverSource Mid Cap Growth Fund and RiverSource
 Partners Aggressive Growth Fund) based on application of the Board's pricing
 philosophy that it applies when considering renewal of the Fund's investment
 management services agreement with the investment manager, which results in the
 total expense ratio of the Fund being set at or below the median expense ratio
 of mutual funds in the same Lipper comparison group; or (iii) RiverSource
 Partners Aggressive Growth Fund's current expense cap commitment pursuant to
 which net fund expenses (excluding fees and expenses of acquired funds), before
 giving effect to any performance incentive adjustment, will not exceed 1.28%
 for Class A shares, and that, based on this commitment, the gross expense ratio
 of RiverSource Partners Aggressive Growth Fund is expected to decline by at
 least 0.36%, as a result of the Reorganization. With respect to the Board's
 review of the expense impact on RiverSource Mid Cap Growth Fund's shareholders,
 the Board took into account that, although the net expense ratios for the
 Fund's Class A, Class B and Class C shares would increase slightly after giving
 effect to the Reorganization, the additional expense cap commitment by the
 investment manager and its affiliates would have the effect of reducing
 expenses going forward (or preventing likely future increases).

 Proposal 2: Reorganization of RiverSource Partners Select Value Fund into
 RiverSource Mid Cap Value Fund: The Board considered that, based on most recent
 fiscal year-end data, the gross expense ratio and net expense ratio (reflecting
 a contractual fee waiver and expense reimbursement) of RiverSource Partners
 Select Value Fund (before giving effect to any applicable performance incentive
 adjustment and excluding certain other fees and expenses) are higher than the
 respective expense ratios of RiverSource Mid Cap Value Fund (except for Class
 A, Class B and Class C shares), which currently does not have an expense cap.
 The Board observed current expense trends and considered the commitment of the
 investment

                                       78






 manager and its affiliates to waive certain fees and expenses for one year
 following the effective date of the Reorganization based on the least of (i)
 RiverSource Mid Cap Value Fund's expense ratio (before giving effect to any
 performance incentive adjustment) as of its fiscal year-end on September 30,
 2009, which was 1.31% for Class A shares; or (ii) RiverSource Mid Cap Value
 Fund's expense cap (including the assets of both RiverSource Mid Cap Value Fund
 and RiverSource Partners Select Value Fund) based on application of the Board's
 pricing philosophy that it applies when considering renewal of the Fund's
 investment management services agreement with the investment manager, which
 would result in the total expense ratio of the Fund being set at or below the
 median expense ratio of mutual funds in the same Lipper comparison group, and
 that the gross expense ratio of RiverSource Partners Select Value Fund is
 expected to decline by at least 0.34%. With respect to the Board's review of
 the expense impact on RiverSource Mid Cap Value Fund's shareholders, the Board
 took into account that, although the net expense ratios for the Fund's Class A,
 Class B and Class C shares would increase slightly, the increase likely would
 have occurred irrespective of the Reorganization (based on current assets of
 the Fund), and the additional expense cap commitment by the investment manager
 and its affiliates would have the effect of reducing expenses going forward (or
 preventing likely future increases).

 Proposal 3: Reorganization of RiverSource Partners Small Cap Equity Fund into
 Seligman Smaller-Cap Value Fund: The Board considered that, based on most
 recent fiscal year-end data, the gross expense ratio and net expense ratio
 (reflecting a contractual fee waiver and expense reimbursement) of RiverSource
 Partners Small Cap Equity Fund (before giving effect to any applicable
 performance incentive adjustment and excluding certain other fees and expenses)
 are higher than or the same as the gross expense ratio and net expense ratio of
 Seligman Smaller-Cap Value Fund. The Board also considered the commitment of
 the investment manager and its affiliates to waive certain fees and expenses
 for one year following the effective date of the merger based on the least of
 (i) Seligman Smaller-Cap Value Fund's expense ratio (before giving effect to
 any performance incentive adjustment) as of its fiscal year-end on December 31,
 2009; (ii) Seligman Smaller-Cap Value Fund's expense cap (including the assets
 of both Seligman Smaller-Cap Value Fund and RiverSource Partners Small Cap
 Equity Fund) based on application of the Board's pricing philosophy that it
 applies when considering renewal of the Fund's investment management services
 agreement with the investment manager, which would result in the total expense
 ratio of the Fund being set at or below the median expense ratio of mutual
 funds in the same Lipper comparison group; or (iii) RiverSource Partners Small
 Cap Equity Fund's current expense cap commitment pursuant to which net fund
 expenses (excluding fees and expenses of acquired funds) before giving effect
 to any performance incentive adjustment, will not exceed 1.33% for Class A
 shares, and that, based on this commitment, the gross expense ratio of
 RiverSource Partners Small Cap Equity Fund is expected to decrease by at least
 0.03% and there would be no change to net expenses as a result of the
 Reorganization. The Board also took into account that shareholders of
 RiverSource Partners Small Cap Equity Fund are subject to a performance
 incentive arrangement, while Seligman Smaller-Cap Value Fund has no such
 arrangement.

 Proposal 4: Reorganization of RiverSource Partners Small Cap Growth Fund into
 Seligman Frontier Fund: The Board observed that, based on most recent fiscal
 year-end data, although the gross expense ratio of RiverSource Partners Small
 Cap Growth Fund (before giving effect to any applicable performance incentive
 adjustment and excluding certain other fees and expenses) is expected to
 increase by 0.06% as a result of the Reorganization, the net expense ratio
 would be the same (no increase) as a result of the commitment to waive fees and
 cap expenses by the investment manager and its affiliates. The Board also took
 into account that shareholders of RiverSource Partners Small Cap Growth Fund
 are subject to a performance incentive arrangement, which could potentially
 impact the Fund's expenses, while Seligman Frontier Fund has no such
 arrangement.

 Proposal 5: Reorganization of Seligman Global Smaller Companies Fund into
 RiverSource Partners International Small Cap Fund: The Board noted that, based
 on most recent fiscal year-end data, although the gross expense ratio (before
 giving effect to any applicable performance incentive adjustment and excluding
 certain other fees and expenses) of Seligman Global Smaller Companies Fund, is
 expected to increase by 0.20%, the net expense ratio would decline by 0.12%, as
 a result of the commitment to waive fees and cap expenses by the investment
 manager and its affiliates. The Board also observed that Seligman Global
 Smaller Companies Fund Class R2 and Class R5 shares would each experience a
 modest increase in net expenses as a result of the Reorganization. Further, the
 Board took into account that shareholders of RiverSource Partners International
 Small Cap Fund are subject to a performance incentive arrangement, which could
 potentially impact the Fund's expenses, while Seligman Global Smaller Companies
 Fund has no such arrangement.

 Proposal 6: Reorganization of RiverSource Tax-Exempt Money Market Fund into
 RiverSource Government Money Market Fund: The Board noted that, based on most
 recent fiscal year-end data, although the gross expense ratio (excluding
 certain applicable fees and expenses) of RiverSource Tax-Exempt Money Market
 Fund is expected to increase by 0.23% as a result of the Reorganization, the
 net expense ratio would decline by 0.02% as a result of the Reorganization
 based on the commitment by the investment manager and its affiliates to waive
 fees and cap expenses.

- ECONOMIES OF SCALE. The Board observed that by combining the Funds, in
  addition to potential immediate economies of scale of a larger fund, the
  combined Fund would be able to take advantage of other economies of scale
  associated with a

                                       79



  larger fund. For example, a larger fund may realize breakpoints more quickly,
  it should have an enhanced ability to effect portfolio transactions on more
  favorable terms and may have greater investment flexibility. Furthermore, the
  Board also considered that higher aggregate net assets resulting from each
  Reorganization and the opportunity for net cash inflows (or reduced outflows)
  may reduce the risk that, if net assets of the Selling Fund fail to grow, or
  diminish, its total expense ratio could rise from current levels as fixed
  expenses, such as audit expenses and accounting expenses that are charged on a
  per Fund basis, become a larger percentage of net assets.

- COSTS. The Board considered the fact that the investment manager and its
  affiliates have agreed to bear all solicitation expenses associated with each
  Reorganization and to bear any other costs of effecting each Reorganization
  (other than any brokerage or other transaction costs associated with the sale
  or purchase of portfolio securities in connection with the Reorganization).

- DILUTION. The Board considered the fact that the Reorganization will not
  dilute the interests of the current shareholders because it would be effected
  on the basis of the relative net asset value per share of the Selling Fund and
  Buying Fund, respectively. Thus, for example, a Class A shareholder of a
  Selling Fund will receive Class A shares of the corresponding Buying Fund
  equal in value to his or her Class A shares in the Selling Fund at the time of
  the Reorganization.

- PERFORMANCE AND OTHER FACTORS. The Board considered the relative performance
  records of each of the Funds, noting, however, that past performance is no
  guarantee of future results. The Board also considered the fact that the
  Reorganizations should allow for a more concentrated selling effort by the
  Funds' distributor, thereby potentially benefiting each of the Funds, and that
  reduced outflows or increased inflows could help all Fund shareholders achieve
  further economies of scale (see "Economies of Scale" above). The Board further
  took into account the investment manager's belief that each Selling Fund, as a
  stand-alone fund, was less likely to experience any growth in assets from
  investor inflows in the near term. In particular, for each Reorganization the
  Board observed:

 Proposal 1: Reorganization of RiverSource Partners Aggressive Growth Fund into
 RiverSource Mid Cap Growth Fund: The Board observed the generally stronger
 track record of RiverSource Mid Cap Growth Fund, but noted that both
 RiverSource Partners Aggressive Growth Fund and RiverSource Mid Cap Growth Fund
 are currently run by the same management team, and, thus, their respective
 performance, going forward, absent the Reorganization, would be substantially
 similar given the similar objectives and strategies of the Funds. The Board
 noted the weak asset levels of RiverSource Partners Aggressive Growth Fund and
 its relative weak prospects for asset growth, particularly compared to
 RiverSource Mid Cap Growth Fund. The Board accorded particular weight to the
 fact that RiverSource Mid Cap Growth Fund was more than 2 times the size of
 RiverSource Partners Aggressive Growth Fund.

 Proposal 2: Reorganization of RiverSource Partners Select Value Fund into
 RiverSource Mid Cap Value Fund: The Board noted that the performance of
 RiverSource Mid Cap Value Fund over the long term was generally stronger that
 the performance of RiverSource Partners Select Value Fund (both on a relative
 basis and when compared to their respective peer groups) and that both
 RiverSource Partners Select Value Fund and RiverSource Mid Cap Value Fund are
 currently run by the same management team, and, thus, their respective
 performance, going forward, absent the Reorganization, would be substantially
 similar given the similar objectives and strategies of the Funds. The Board
 also noted the relative weak prospects for asset growth for RiverSource
 Partners Select Value Fund compared to RiverSource Mid Cap Value Fund. The
 Board accorded particular weight to the fact that RiverSource Mid Cap Value
 Fund was more than 6 times the size of RiverSource Partners Select Value Fund.

 Proposal 3: Reorganization of RiverSource Partners Small Cap Equity Fund into
 Seligman Smaller-Cap Value Fund: The Board observed that the performance of
 RiverSource Partners Small Cap Equity Fund is similar to Seligman Smaller-Cap
 Value Fund and that both Funds are currently managed by the same investment
 management team; however, absent the Reorganization, RiverSource Partners Small
 Cap Equity Fund has weak prospects for asset growth compared to Seligman
 Smaller-Cap Value Fund. The Board accorded particular weight to the fact that
 Seligman Smaller-Cap Value Fund was 3 times the size of RiverSource Partners
 Small Cap Equity Fund.

 Proposal 4: Reorganization of RiverSource Partners Small Cap Growth Fund into
 Seligman Frontier Fund: The Board observed that the performance of RiverSource
 Partners Small Cap Growth Fund is similar to Seligman Frontier Fund and that
 both Funds are currently managed by the same investment management team;
 however, absent the Reorganization, RiverSource Partners Small Cap Growth Fund
 has weak prospects for asset growth compared to Seligman Frontier Fund.

 Proposal 5: Reorganization of Seligman Global Smaller Companies Fund into
 RiverSource Partners International Small Cap Fund: The Board observed that the
 performance of RiverSource Partners International Small Cap Fund was
 competitive, though not as good as the performance of Seligman Global Smaller
 Companies Fund.

 Proposal 6: Reorganization of RiverSource Tax-Exempt Money Market Fund into
 RiverSource Government Money Market Fund: The Board observed that, in the
 current market conditions, both Funds are being capped to maintain a positive
 yield.

                                       80






 The Board also noted that RiverSource Tax-Exempt Money Market Fund is small
 and, unless money market rates change significantly, the Fund is likely to
 continue experiencing net outflows, further reducing assets and increasing Fund
 expenses.

- POTENTIAL BENEFITS TO THE INVESTMENT MANAGER AND ITS AFFILIATES. The Board
  considered the potential benefits from the Reorganizations that could be
  realized by the investment manager and its affiliates, including the
  elimination of expenses incurred in duplicative efforts to administer separate
  Funds. The Board also noted, however, that shareholders of each Selling Fund
  are expected to benefit over time from any decrease in overall operating
  expense ratios resulting from the proposed Reorganizations in addition to the
  other benefits discussed above.

BOARD DETERMINATIONS

After considering the factors described above and other relevant information, at
a meeting held on November 12, 2009, each Selling Fund Board, and each Buying
Fund including a majority of the independent Board members, found that
participation in the relevant Reorganization is in the best interests of each
Fund and that the interests of existing shareholders of the Fund will not be
diluted as a result of the Reorganization.

Fund will not be diluted as a result of the Reorganization.

BOARD RECOMMENDATION AND REQUIRED VOTE

The Board recommends that shareholders of each Selling Fund approve its proposed
Agreement.

For RiverSource Partners Aggressive Growth Fund, RiverSource Partners Select
Value Fund, RiverSource Partners Small Cap Equity Fund, RiverSource Partners
Small Cap Growth Fund and RiverSource Tax-Exempt Money Market Fund, the
Agreement must be approved by a majority of the voting power of all shares
entitled to vote.

For Seligman Global Smaller Companies Fund, the Agreement must be approved by
the affirmative vote of a majority of the outstanding voting securities of the
Selling Fund. A vote of a majority of the outstanding voting securities of the
Selling Fund is defined in the 1940 Act as the affirmative vote of the lesser of
(a) 67% or more of the shares of the Selling Fund that are present or
represented by proxy at the Meeting, if the holders of more than 50% of the
outstanding shares of the Selling Fund are present or represented by proxy at
the Meeting; or (b) more than 50% of the outstanding shares of the Selling Fund.

If the Agreement is not approved for any Selling Fund, the Board will consider
what further action should be taken with respect to such Selling Fund. The
approval of the Reorganization of one Selling Fund is not conditioned upon the
approval of the Reorganization of any other Selling Fund.

If shareholders approve the Reorganization of their Selling Fund, it is
anticipated to occur before the end of the second quarter of 2010.

SECTION B -- PROXY VOTING AND SHAREHOLDER MEETING INFORMATION

Reference to the "Fund" in this section is a reference to each Selling Fund.
References to the "RiverSource Selling Funds" in this section are references to
RiverSource Partners Aggressive Growth Fund, RiverSource Partners Select Value
Fund, RiverSource Partners Small Cap Equity Fund, RiverSource Partners Small Cap
Growth Fund and RiverSource Tax-Exempt Money Market Fund. References to the
"Seligman Selling Fund" in this section are references to Seligman Global
Smaller Companies Fund.

VOTING. Shareholders of record of each of RiverSource Partners Aggressive Growth
Fund, RiverSource Partners Select Value Fund, RiverSource Partners Small Cap
Equity Fund, RiverSource Partners Small Cap Growth Fund and RiverSource Tax-
Exempt Money Market Fund on Jan. 15, 2010 are entitled to vote based on their
total dollar interest in the Fund irrespective of which class they own.
Shareholders of record of Seligman Global Smaller Companies Fund on Jan. 15,
2010 are entitled to vote based on the number of shares they own in the Fund
irrespective of which class they own. Unless otherwise restricted by the 1940
Act or by applicable state law, all share classes of a Selling Fund will vote
together as a class on its proposed Reorganization.

A quorum is required to take action at the Meeting. With respect to the
RiverSource Selling Funds, the presence at the Meeting, in person or by proxy,
of shareholders entitled to cast at least ten percent (10%) of the shares
outstanding and entitled to vote at the Meeting shall constitute a quorum. With
respect to the Seligman Selling Fund, the presence at the Meeting, in person or
by proxy, of at least one-third of all shares outstanding and entitled to vote
at the Meeting shall constitute a quorum.

All votes count toward a quorum, regardless of how they are voted (For, Against
or Abstain). Broker non-votes will be counted toward a quorum but not toward the
approval of any proposal. (Broker non-votes are shares for which the underlying
owner has not voted and the broker holding the shares does not have authority to
vote.)

If your shares are held in an IRA account with Ameriprise Trust Company as
custodian, you have the right to instruct the IRA Custodian how to vote those
shares. The IRA Custodian will vote any shares for which it has not received
voting instructions in proportionately the same manner -- either For, Against,
or Abstain -- as other Fund shareholders have voted.

PROXY SOLICITATION. If you properly authorize your proxy by internet, telephone
or facsimile, or by executing and returning the enclosed proxy card by mail, and
your proxy is not subsequently revoked, your votes will be cast at the Meeting,
and at any postponement or adjournment thereof. If you give instructions, your
votes will be cast in accordance with your instructions. If you return your
signed proxy card without instructions, your votes will be cast in favor of the
Reorganization of your Fund.

PROXY STATEMENT DELIVERY. "Householding" is the term used to describe the
practice of delivering one copy of a document to a household of shareholders
instead of delivering one copy of a document to each shareholder in the
household. Certain shareholders of the Fund who share a common address and who
have not opted out of the householding process may receive a single copy of the
proxy statement along with the proxy card(s). If you received more than one copy
of the proxy statement, you may elect to household in the future if permitted by
your financial intermediary/financial institution. Contact the financial
intermediary/financial institution through which you purchased the Fund to
determine whether householding is an option for your account. If you received a
single copy of the proxy statement, you may opt out of householding in the
future by contacting your financial intermediary/financial institution.

An additional copy of this proxy statement may be obtained by writing to the
following address: Computershare Fund Services, c/o Operation Department, 280
Oser Ave., Hauppauge, NY 11788 or calling Computershare Fund Services, toll free
at 1(866) 859-8682.

REVOKING YOUR PROXY. If you execute, date and submit a proxy card with respect
to your Fund, you may revoke your proxy prior to the voting thereof by providing
written notice to your Fund (Attention: Secretary) at 50606 Ameriprise Financial
Center, Minneapolis, MN 55474 or change your instructions by submitting a
subsequently executed and dated proxy card, by authorizing your proxy by
internet, telephone or facsimile on a later date or by attending the Meeting and
casting your vote in person. If you authorize your proxy by internet, telephone
or facsimile, you may change your instructions prior to the voting thereof by
authorizing a subsequent proxy by internet, telephone or facsimile or by
completing, signing and returning a proxy card dated as of a date that is later
than your last internet, telephone or facsimile proxy authorization or by
attending the Meeting and casting your vote in person. Merely attending the
Meeting without voting will not revoke your prior proxy.

SIMULTANEOUS MEETINGS. The meeting for each Fund will be held simultaneously
with the meeting for each other Fund, with each Reorganization being voted on
separately by the shareholders of the relevant Fund. If any shareholder objects
to the holding of simultaneous meetings, the shareholder may move for an
adjournment of his or her Fund's meeting to a time after the Meeting so that a
meeting for that Fund may be held separately. If a shareholder makes this
motion, the persons named as proxies will take into consideration the reasons
for the objection in deciding whether to vote in favor of the adjournment, and
may vote for or against the adjournment in their discretion.


                                       82



SOLICITATION OF PROXIES. The Board is asking for your vote and for you to vote
as promptly as possible. The investment manager will pay the expenses of the
solicitation. Supplementary solicitations may be made by internet, telephone or
facsimile, or by personal contact. Computershare Fund Services has been engaged
to assist in the solicitation of proxies, at an aggregate estimated cost of
$116,000.

SHAREHOLDER PROPOSALS. No proposals were received from shareholders. The Funds
do not hold annual meetings of shareholders. Shareholders who wish to make a
proposal at a Fund's next special meeting, which may not be included in the
Fund's proxy materials, must notify the relevant Fund a reasonable amount of
time before the Fund begins to print and mail its proxy materials. The fact that
a Fund receives a shareholder proposal in a timely manner does not ensure
inclusion of the proposal in the proxy materials, as there are other
requirements in the proxy rules relating to such inclusion.

DISSENTERS' RIGHT OF APPRAISAL FOR RIVERSOURCE SELLING FUNDS. Under Sections
302A.471 and 302A.473 of the Minnesota Business Corporation Act, the RiverSource
Selling Funds' shareholders are entitled to assert dissenters' rights in
connection with their Selling Fund's Reorganization and obtain payment of the
"fair value" of their shares, provided that they comply with the requirements of
Minnesota law. A copy of the relevant provisions is attached as Exhibit B.

Notwithstanding the provision of Minnesota law, the SEC has taken the position
that the use of state appraisal procedures by a mutual fund would be a violation
of Rule 22c-1, the forward pricing rule, under the 1940 Act. This rule states
that no mutual fund may redeem its shares other than at net asset value next
computed after receipt of a request for redemption. It is the SEC's position
that Rule 22c-1 supersedes appraisal provisions in state statutes.

In the interest of ensuring equal valuation for all shareholders, dissenters'
rights will be determined in accordance with the SEC's interpretation. As a
result, if any shareholder elects to exercise dissenters' rights under Minnesota
law, the RiverSource Selling Funds intend to submit this question to a court of
competent jurisdiction. In that event, a dissenting shareholder would not
receive any payment until the end of the court proceeding.

OTHER BUSINESS. The Board does not know of any matters to be presented at the
Meeting other than the Reorganizations. If other business should properly come
before the Meeting, the persons named as proxies will vote thereon in their
discretion.

ADJOURNMENT. With respect to the RiverSource Selling Fund Reorganizations, in
the event that not enough votes are received by the time scheduled for the
Meeting, the persons named as proxies may move for one or more adjournments of
the Meeting for a period of not more than 120 days of the original record date
for the Meeting in the aggregate to allow further solicitation of shareholders
on the proposal. Any adjournment requires the affirmative vote of a majority of
the voting power of the shares present at the Meeting. With respect to the
Seligman Selling Fund Reorganization, if not enough votes are received by the
time scheduled for the Meeting, or, even if a quorum is present, if sufficient
votes in favor of any Reorganization are not received and tabulated prior to the
time scheduled for the Meeting, the chairman of the Meeting may adjourn the
Meeting, with no notice other than an announcement at the Meeting, to a date not
later than the 120th day after the original record date for the Meeting to allow
further solicitation of shareholders on the proposed Reorganization.

If insufficient votes are received by the time of the Meeting, the persons named
as proxies will vote in favor of adjournment those shares they are entitled to
vote that have voted in favor of the proposal. They will vote against any
adjournment those shares that have voted against the proposal. A shareholder
vote may be taken on one or more of the proposals in this proxy statement prior
to adjournment if sufficient votes have been received with respect to that
particular proposal(s), and may adjourn with respect to those proposals for
which sufficient votes have not yet been received.

THE FUNDS' INVESTMENT MANAGER AND DISTRIBUTOR. RiverSource Investments, LLC, 200
Ameriprise Financial Center, Minneapolis, MN 55474, a wholly-owned subsidiary of
Ameriprise Financial, Inc., is the investment manager for each Fund. RiverSource
Fund Distributors, Inc., 50611 Ameriprise Financial Center, Minneapolis, MN
55474, an indirect wholly-owned subsidiary of RiverSource Investments, LLC, is
the distributor for each Fund.

CAPITALIZATION OF SELLING FUNDS AND BUYING FUNDS

The following table shows the capitalization of the Funds as of Sept. 30, 2009
and on a pro forma basis, assuming the proposed Reorganization had taken place.
The pro forma combined net assets are determined by adding the net assets of the
Selling Fund and the net assets of the Buying Fund. The pro forma combined
shares outstanding are determined by dividing the net assets of the Selling Fund
by the net asset value per share of the Buying Fund and adding the actual shares
outstanding of the Buying Fund.

     RiverSource Investments (investment manager of RiverSource Partners Small
     Cap Growth Fund and the funds-of-funds) do not invest in the Fund for the
     purposes of exercising control. However, since these ownership interests
     may be significant, in excess of 25% of the Fund, such that these entities
     may be deemed to control the Fund, procedures have been put in place to
     assure that public shareholders determine the outcome of all actions taken
     at shareholder meetings. Specifically, RiverSource Investments (which votes
     proxies for the seed accounts) and the funds-of-funds' Boards of Directors
     (which votes proxies for the funds-of-funds) vote on the proposal in the
     same proportion that other shareholders vote on the proposal. If the
     Reorganization is approved, RiverSource Investments and the funds-of-funds
     will own 27.08% of Seligman Frontier Fund.

NOTES TO FINANCIAL HIGHLIGHTS

(a) For a share outstanding throughout the period. Rounded to the nearest cent.
(b) Per share amounts have been calculated using the average shares outstanding
    method.
(c) In addition to the fees and expenses which the Fund bears directly, the Fund
    indirectly bears a pro rata share of the fees and expenses of the acquired
    funds in which it invests. Such indirect expenses are not included in the
    above reported expense ratios.
(d) Adjusted to an annual basis. The Non-Recurring Charges (See Note 3 to the
    Financial Statements) have not been annualized, as they represent a one-time
    occurrence.
(e) Total return does not reflect payment of a sales charge.
(f) Not annualized.
(g) During the six months ended June 30, 2009, the Fund received its portion of
    the proceeds from a regulatory settlement between an unaffiliated third
    party and the Securities and Exchange Commission. Had the Fund not received
    these proceeds, the total return would have been lower by 0.02%.
(h) Excluding the effect of certain payments received from the Fund's
    predecessor investment manager in 2004, total returns would have been as
    follows: Class A 20.57%, Class B 19.60% and Class C 19.60%.
(i) Six months ended June 30, 2009 (Unaudited).

EXHIBIT A

FORM OF AGREEMENT AND PLAN OF REORGANIZATION

This Agreement and Plan of Reorganization dated as of November   , 2009 (the
"Agreement") is between each selling entity identified in Schedule A hereto
(each a "Selling Corporation")(1), on behalf of each series thereof identified
in Schedule A hereto as a Selling Fund (each a "Selling Fund"), each
corresponding buying entity identified in Schedule A hereto (each a "Buying
Corporation")(2), on behalf of each series thereof identified in Schedule A
hereto as the corresponding Buying Fund (each a "Buying Fund"), and RiverSource
Investments, LLC (solely for the purposes of Sections 3c and 11 of the
Agreement).

This Agreement shall be treated for all purposes as if each reorganization
between a Selling Fund and its corresponding Buying Fund contemplated hereby had
been the subject of a separate agreement. As context requires a Buying
Corporation that is not organized as a series fund and that may not be
considered or meet the definition of "Buying Fund" as set forth above, may be
referred to as a "Buying Fund," for purposes of this Agreement.

In consideration of their mutual promises, the parties agree as follows:

1.  SHAREHOLDER APPROVAL. Each Selling Fund will call a meeting of its
    shareholders for the purpose of approving the Agreement and the transactions
    it contemplates (each a "Reorganization"). Each Buying Fund agrees to
    furnish data and information, as reasonably requested, for the proxy
    statement to be furnished to shareholders of the corresponding Selling Fund.

2.  REORGANIZATION.

   a. Plan of Reorganization. Each Reorganization will be a reorganization
      within the meaning of Section 368(a) of the Internal Revenue Code of 1986,
      as amended (the "Code"). At the Closing, each Selling Corporation will
      convey all of the assets of each Selling Fund to the corresponding Buying
      Fund. Each Buying Fund will assume all liabilities of the corresponding
      Selling Fund. At the Closing, each Buying Corporation will deliver shares
      of each Buying Fund, including fractional shares, to the corresponding
      Selling Corporation on behalf of the corresponding Selling Fund. The
      number of shares will be determined by dividing the value of the net
      assets attributable to each class of shares of each Selling Fund, computed
      as described in paragraph 3(a), by the net asset value of one share of the
      corresponding class of the corresponding Buying Fund, computed as
      described in paragraph 3(b). Each Selling Fund will not pay a sales charge
      on the receipt of the corresponding Buying Fund's shares in exchange for
      the assets of such Selling Fund. In addition, the shareholders of each
      Selling Fund will not pay a sales charge on distribution to them of shares
      of the corresponding Buying Fund.

   b. Closing and Effective Time of the Reorganization. The Reorganization and
      all related acts necessary to complete the Reorganization (the "Closing")
      will occur on the first day on which the New York Stock Exchange (the
      "NYSE") is open for business following approval of shareholders of each
      Selling Fund and receipt of all necessary regulatory approvals, or such
      later date as the officers of the Selling Corporation and Buying
      Corporation may agree.

3.  VALUATION OF NET ASSETS.

   a. The net asset value of each Selling Fund will be computed as of the close
      of regular trading on the NYSE on the business day immediately preceding
      the day of Closing (the "Valuation Date") using the valuation procedures
      set forth in the corresponding Buying Fund's then current prospectus.

   b. The net asset value per share of shares of each Buying Fund will be
      determined as of the close of regular trading on the NYSE on the Valuation
      Date, using the valuation procedures set forth in each Buying Fund's then
      current prospectus.

   c. At the Closing, each Selling Fund will provide the corresponding Buying
      Fund with a copy of the computation showing the valuation of the net asset
      value per share of such Selling Fund on the Valuation Date, and each
      Buying Fund will provide the corresponding Selling Fund with a copy of the
      computation showing the determination of the net asset value per share of
      such Buying Fund on the Valuation Date. Both computations will be
      certified by an officer of RiverSource Investments, LLC, the investment
      manager.

4.  LIQUIDATION AND DISSOLUTION OF THE SELLING FUND.

   a. On the date of the Closing, each Selling Corporation will liquidate each
      Selling Fund and distribute shares of each class of the corresponding
      Buying Fund to the shareholders of record of such Selling Fund's
      corresponding class. Each Buying Fund will establish shareholder accounts
      in the names of each corresponding Selling Fund shareholder, representing
      the respective pro rata number of full and fractional shares of such class
      of the Buying Fund due to each such shareholder. All issued and
      outstanding shares of each Selling Fund will simultaneously be cancelled
      on the books of each Selling Corporation. Each Buying Fund or its transfer
      agent will establish shareholder accounts in accordance with instructions
      from the corresponding Selling Corporation.

   b. Immediately after the close of business on the Valuation Date, the share
      transfer books of each Selling Corporation relating to each Selling Fund
      will be closed and no further transfer of shares will be made.

   c. Promptly after the Closing, each Buying Fund or its transfer agent will
      notify each shareholder of the corresponding Selling Fund of the number of
      shares distributed to the shareholder and confirm the registration in the
      shareholder's name.

   d. As promptly as practicable after the Closing, and in no event later than
      twelve months from the date of the Closing, each Selling Fund will be
      dissolved.

5.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BUYING CORPORATION.

   With respect to each Reorganization, each Buying Corporation represents and
   warrants to the corresponding Selling Fund as follows:

   a. Organization, Existence, etc. Each Buying Corporation is a corporation
      duly organized, validly existing and in good standing under the laws of
      the state of Maryland or Minnesota and has the power to carry on its
      business as it is now being conducted.

   b. Registration as Investment Company. Each Buying Corporation, or in the
      case of separate series funds, the Buying Corporation, of which the Buying
      Fund is a series, is registered under the Investment Company Act of 1940
      (the "1940 Act") as an open-end, management investment company.

   c. Capitalization. Each Buying Corporation for the Buying Fund, RiverSource
      Mid Cap Growth Fund, RiverSource Mid Cap Value Fund and RiverSource
      Partners International Small Cap Fund has authorized capital of
      10,000,000,000 shares of common stock, par value $0.01 per share that can
      be allocated among the separate series as designated by the Corporation's
      Board of Directors. The Buying Corporation for Seligman Smaller-Cap Value
      Fund has authorized capital of 2,000,000,000 shares of common stock, par
      value of $0.001 per share, of which 1,000,000,000 are authorized for
      Seligman Smaller-Cap Value Fund. The Buying Corporation RiverSource
      Government Money Market Fund, Inc. has authorized capital of 1,400,000,000
      shares of common stock, par value of $0.01 per share. The Buying
      Corporation Seligman Frontier Fund, Inc. has authorized capital of
      500,000,000 shares of common stock, par value of $0.10 per share. All of
      the outstanding shares of each Buying Corporation have been duly
      authorized and are validly issued, fully paid and non-assessable. Since
      each Buying Fund is engaged in the continuous offering and redemption of
      its shares, the number of outstanding shares may vary daily.

   d. Financial Statements. Each Buying Fund's audited financial statements as
      of the end of the last fiscal year, and the subsequent unaudited semi-
      annual financial statements, if any (the "Buying Fund Financial
      Statements"), fairly present the financial position of the Buying Fund and
      the results of its operations and changes in its net assets for the
      periods shown.

   e. Shares to be Issued Upon Reorganization. The shares to be issued in
      connection with the Reorganization will be duly authorized and, at the
      time of the Closing, will be validly issued, fully paid and non-
      assessable.

   f. Authority Relative to the Agreement. Each Buying Corporation has the power
      to enter into and carry out the obligations described in this Agreement.
      The Agreement and the transactions contemplated by it have been duly
      authorized by the Board of Directors of each Buying Corporation and no
      other proceedings by any of the Buying Corporation or the Buying Funds are
      necessary.

   g. No Violation. The Buying Corporation is not in violation of its Articles
      of Incorporation or By-Laws (the "Articles") or in default in the
      performance of any material agreement to which it is a party. The
      execution of this Agreement and the completion of the transactions
      contemplated by it will not conflict with, or constitute a breach of, any
      material contract or other instrument to which each Buying Fund is
      subject. The transactions will not result in any violation of the
      provisions of the Articles or any law, administrative regulation or
      administrative or court decree applicable to the Buying Funds.


                                       A.2



   h. Liabilities. The Buying Funds have no known liabilities of a material
      amount, contingent or otherwise, other than liabilities disclosed in each
      Buying Fund's Financial Statements, liabilities incurred in the ordinary
      course of business subsequent to the date of the latest annual or semi-
      annual financial statements, or liabilities previously disclosed to the
      corresponding Selling Fund.

   i. Litigation. There is no litigation, administrative proceeding or
      investigation before any court or governmental body currently pending or,
      to the knowledge of the Buying Funds, threatened, that would materially
      and adversely affect the Buying Funds, their financial condition or the
      conduct of their business, or that would prevent or hinder completion of
      the transactions contemplated by this Agreement. The Buying Funds know of
      no facts that might form the basis for the institution of any such
      litigation, proceeding or investigation and the Buying Funds are not a
      party to or subject to the provisions of any order, decree or judgment.

   j. Contracts. Except for contracts and agreements previously disclosed to the
      Selling Corporation, the Buying Funds are not a party to or subject to any
      material contract, debt instrument, plan, lease, franchise, license or
      permit.

   k. Regulated Investment Company Qualification. Each Buying Fund has qualified
      and met the requirements for treatment as a "regulated investment company"
      within the meaning of Section 851 of the Code with respect to each taxable
      year since commencement of its operations and will continue to meet such
      requirements and to so qualify at all times through the Closing.

   l. Taxes. As of the Closing, each Buying Fund will (i) have filed all federal
      and other tax returns and reports that have been required to be filed,
      (ii) have paid or provided for payment of all federal and other taxes
      shown to be due on such returns or on any assessments received, (iii) have
      adequately provided for all tax liabilities on its books, (iv) except as
      disclosed to the Selling Fund, not have had any tax deficiency or
      liability asserted against it or question with respect thereto raised, and
      (v) except as disclosed to the Selling Fund, not be under audit by the
      Internal Revenue Service or by any state or local tax authority for taxes
      in excess of those already paid.

   m. Registration Statement. Each Buying Fund will file a registration
      statement on Form N-14 (the "Registration Statement") with the Securities
      and Exchange Commission under the Securities Act of 1933 (the "1933 Act")
      relating to the shares to be issued in the Reorganization. At the time the
      Registration Statement becomes effective, at the time of the shareholders'
      meeting described in paragraph 1 and at the Closing, the Registration
      Statement will not contain an untrue statement of a material fact or omit
      to state a material fact necessary to make the statements therein not
      misleading. However, none of the representations and warranties in this
      subsection apply to statements in, or omissions from, the Registration
      Statement made in reliance on information furnished by the Selling Fund
      for use in the Registration Statement.

   n. Business Activities. Each Buying Fund will operate its business in the
      ordinary course between the date hereof and the date of the Closing, it
      being understood that such ordinary course of business will include
      regular and customary periodic dividends and distributions and any other
      distribution that may be advisable.

      the state of Minnesota or Maryland and has the power to carry on its

      Selling Fund is a series, is registered under the 1940 Act as an open-end,
      management investment company.

   c. Capitalization. Each Selling Corporation for the Selling Fund, RiverSource
      Partners Aggressive Growth Fund, RiverSource Partners Select Value Fund,
      RiverSource Partners Small Cap Equity Fund, RiverSource Partners Small Cap
      Growth Fund and RiverSource Tax-Exempt Money Market Fund, has authorized
      capital of 10,000,000,000 shares of common stock, par value $0.01 per
      share that can be allocated among the separate series as designated by the
      Corporation's Board of Directors. The Selling Corporation for the Selling
      Fund, Seligman Global Smaller Companies Fund has authorized capital of
      2,000,000,000 shares of common stock, par value $0.001 per share, of which
      400,000,000 are authorized for Seligman Global Smaller Companies Fund. All
      of the outstanding shares have been duly authorized and are validly
      issued, fully paid and nonassessable. Since each Selling Fund is engaged
      in the continuous offering and redemption of its shares, the number of
      outstanding shares may vary daily.

   d. Financial Statements. Each Selling Fund's audited financial statements as
      of the end of the last fiscal year, and the subsequent unaudited semi-
      annual financial statements, if any (the "Selling Fund Financial
      Statements"), fairly present

                                       A.3



      the financial position of the Selling Fund, and the results of its
      operations and changes in its net assets for the periods shown.

   e. Authority Relative to the Agreement. Each Selling Corporation has the
      power to enter into and to carry out its obligations under this Agreement.
      The Agreement and the transactions contemplated by it have been duly
      authorized by the Board of Directors of each Selling Corporation and no
      other proceedings by the Selling Corporations or the Selling Funds are
      necessary, other than the approval of shareholders contemplated in
      paragraph 1.

   f. No Violation. Each Selling Corporation is not in violation of its Articles
      or in default in the performance of any material agreement to which it is
      a party or in default in the performance of any material agreement to
      which it is a party). The execution of this Agreement and the completion
      of the transactions contemplated by it will not conflict with or
      constitute a breach of, any material contract to which the Selling Funds
      are subject. The transactions will not result in any violation of the
      provisions of the Articles, as the case may be, or any law, administrative
      regulation or administrative or court decree applicable to the Selling
      Funds.

   g. Liabilities. The Selling Funds have no known liabilities of a material
      amount, contingent or otherwise, other than liabilities disclosed in the
      Selling Fund Financial Statements, liabilities incurred in the ordinary
      course of business subsequent to the date of the latest annual or semi-
      annual financial statements, or liabilities previously disclosed to each
      Buying Fund.

   h. Litigation. There is no litigation, administrative proceeding or
      investigation before any court or governmental body currently pending or,
      to the knowledge of the Selling Funds, threatened, that would materially
      and adversely affect the Selling Funds, their financial condition or the
      conduct of their business, or that would prevent or hinder completion of
      the transactions contemplated by this Agreement. Each Selling Fund knows
      of no facts that might form the basis for the institution of any such
      litigation, proceeding or investigation and is not a party to or subject
      to the provisions of any order, decree or judgment.

   i. Contracts. Except for contracts and agreements previously disclosed to the
      Buying Corporations, each Selling Fund is not a party to or subject to any
      material contract, debt instrument, plan, lease, franchise, license or
      permit.

   j. Regulated Investment Company Qualification. Each Selling Fund has
      qualified and met the requirements for treatment as a "regulated
      investment company" within the meaning of Section 851 of the Code with
      respect to each taxable year since commencement of its operations and will
      continue to meet such requirements and to so qualify at all times through
      the Closing.

   k. Taxes. As of the Closing, each Selling Fund will (i) have filed all
      federal and other tax returns and reports that have been required to be
      filed, (ii) have paid or provided for payment of all federal and other
      taxes shown to be due on such returns or on any assessments received,
      (iii) have adequately provided for all tax liabilities on its books, (iv)

      deficiency or liability asserted against it or question with respect
      thereto raised, and (v) except as disclosed to the corresponding Buying
      Fund, not be under audit by the Internal Revenue Service or by any state
      or local tax authority for taxes in excess of those already paid.

      each Selling Fund as of the Closing will be owned by each Selling Fund
      free and clear of any encumbrances, except as indicated in the schedule.

   m. Registration Statement. The Selling Funds will cooperate with the Buying
      Funds and will furnish information relating to the Selling Corporations
      and the Selling Funds required in the Registration Statement. At the time
      the Registration Statement becomes effective, at the time of the
      shareholders' meeting described in paragraph 1 and at the Closing, the
      Registration Statement, as it relates to the Selling Corporations or the
      Selling Funds, will not contain an untrue statement of a material fact or
      omit to state a material fact necessary to make the statements therein not
      misleading. However, the representations and warranties in this subsection
      apply only to statements in or omissions from the Registration Statement
      made in reliance upon information furnished by the Selling Corporations or
      the Selling Funds for use in the Registration Statement.

   n. Provision of Books and Records. Each Selling Fund will provide its books
      and records to the corresponding Buying Fund for purposes of preparing any
      tax returns required by law to be filed after the Closing date, including
      (1) the tax return for the period ending on the Closing date, and (2) the
      tax return for the period beginning the day after the Closing and ending
      the earlier of the current fiscal year-end of the corresponding Buying
      Fund and the taxable year end chosen by the corresponding Buying Fund
      following the Reorganization.

   o. Business Activities. Each Selling Fund will operate its business in the
      ordinary course between the date hereof and the date of the Closing, it
      being understood that such ordinary course of business will include
      regular and customary periodic dividends and distributions and any other
      distribution that may be advisable.

9.  CONDITIONS TO OBLIGATIONS OF THE SELLING CORPORATION AND THE BUYING
    CORPORATION. The obligations of each of the Selling Corporation and the
    Buying Corporation with respect to each Reorganization are subject to the
    satisfaction of the following conditions:

   Tax Opinions. With respect to each Reorganization between a Selling Fund and
   its corresponding Buying Fund, the Selling Fund shall have received an
   opinion of Ropes & Gray LLP satisfactory to such Selling Fund, and the Buying
   Fund shall have received an opinion of Ropes & Gray LLP satisfactory to such
   Buying Fund, substantially to the effect that, on the basis of existing
   provisions of the Code, Treasury regulations promulgated thereunder, current
   administrative rules, pronouncements and court decisions, although, with
   respect to the Reorganizations of RiverSource Partners Aggressive Growth Fund
   into RiverSource Mid Cap Growth Fund, RiverSource Partners Select Value Fund
   into RiverSource Mid Cap Value Fund, RiverSource Partners Small Cap Equity
   Fund into Seligman Smaller-Cap Value Fund, RiverSource Partners Small Cap
   Growth Fund into Seligman Frontier Fund and Seligman Global Smaller Companies
   Fund into RiverSource Partners International Small Cap Fund, the matter is
   not free from doubt, generally for federal income tax purposes:

   a. The acquisition by the Buying Fund of the assets of the Selling Fund in
      exchange for the Buying Fund's assumption of all liabilities of the
      Selling Fund and delivery to the Selling Fund of Buying Fund shares (the
      "Acquisition Shares"), followed by the distribution by the Selling Fund of
      the Acquisition Shares to the shareholders of the Selling Fund in exchange
      for their Selling Fund shares, all as provided in paragraph 2(a) and 4(a)
      hereof, will constitute a reorganization within the meaning of Section
      368(a) of the Code, and the Selling Fund and the Buying Fund will each be
      "a party to a reorganization" within the meaning of Section 368(b) of the
      Code;

   b. No gain or loss will be recognized by the Selling Fund upon (i) the
      transfer of its assets to the Buying Fund in exchange for the Acquisition
      Shares and the assumption by the Buying Fund of all liabilities of the
      Selling Fund or (ii) the distribution of the Acquisition Shares by each
      Selling Fund to its shareholders in liquidation, as contemplated in
      paragraph 4(a) hereof;

   c. No gain or loss will be recognized by the Buying Fund upon receipt of the
      assets of the Selling Fund in exchange for the Acquisition Shares and the
      assumption by the Buying Fund of all liabilities of the Selling Fund as
      contemplated in paragraph 2(a) hereof;

   d. The tax basis in the hands of the Buying Fund of the assets of the Selling
      Fund transferred to the Buying Fund in the Reorganization will be the same
      as the tax basis of such assets in the hands of the Selling Fund
      immediately prior to the transfer;


                                       A.6



   e. The holding periods of the assets of the Selling Fund in the hands of the
      Buying Fund will include the periods during which such assets were held by
      the Selling Fund;

   f. No gain or loss will be recognized by the Selling Fund's shareholders upon
      the exchange of their shares of the Selling Fund for the Acquisition
      Shares;

   g. The aggregate tax basis of the Acquisition Shares a Selling Fund
      shareholder receives in the Reorganization will be the same as the
      aggregate tax basis of his or her Selling Fund shares exchanged therefor;

   h. Each Selling Fund shareholder's holding period for the Acquisition Shares
      will include the period for which he or she held the Selling Fund shares
      exchanged therefor, provided that the shareholder held such Selling Fund's
      shares as capital assets on the date of the exchange; and

   i. The Buying Fund will succeed to and take into account the items of the
      Selling Fund described in Section 381(c) of the Code, subject to the
      conditions and limitations specified in Sections 381, 382, 383 and 384 of
      the Code and the regulations thereunder.

   Ropes & Gray LLP will express no view with respect to the effect of the
   Reorganization on any transferred asset as to which any unrealized gain or
   loss is required to be recognized under federal income tax principles (i) at
   the end of a taxable year or upon the termination thereof or (ii) upon the
   transfer of such asset regardless of whether such a transfer would otherwise
   be a non-taxable transaction.

   Each opinion will be based on certain factual certifications made by officers
   of each Selling Fund and each Buying Fund, and will also be based on
   customary assumptions. The opinions are not guarantees that the tax
   consequences of the Reorganizations will be as described above. With respect
   to the Reorganizations listed above, the opinions will note and distinguish
   certain published precedent. There is no assurance that the Internal Revenue
   Service or a court would agree with the opinions.

10. AMENDMENT; TERMINATION; NON-SURVIVAL OF COVENANTS, WARRANTIES AND
REPRESENTATIONS.

   a. This Agreement may be amended in writing if authorized by the respective
      Boards of Directors. The Agreement may be so amended at any time before or
      after the shareholder approval contemplated by paragraph 1 is obtained.

   b. At any time prior to the Closing, any of the parties may waive in writing
      (i) any inaccuracies in the representations and warranties made to it and
      (ii) compliance with any of the covenants or conditions made for its
      benefit.

   c. Each party hereto may terminate this Agreement at any time prior to the
      Closing by notice to the other party if a material condition to its
      performance or a material covenant of the other party is not fulfilled on
      or before the date specified for its fulfillment or a material breach of
      this Agreement is made by the other party and is not cured.

   d. This Agreement may be terminated by any party at any time prior to the
      Closing, whether before or after approval by the shareholders of each
      Selling Fund, without any liability on the part of any party or its
      respective directors, officers, or shareholders, on written notice to the
      other party, and shall be terminated without liability as of the close of
      business on           , or a later date agreed upon by the officers of the
      Selling Corporations and the Buying Corporations, if the Closing is not
      effected on or prior to that date.

   e. The representations, warranties and covenants contained in this Agreement,
      or in any document delivered in connection with this Agreement, will
      survive the Reorganization.

11. EXPENSES. RiverSource Investments, LLC and its affiliates will pay all
    solicitation expenses in order to achieve shareholder approval of each
    Reorganization whether or not the Reorganization is completed and will bear
    the other costs of effecting each Reorganization (other than any brokerage
    or other transaction costs associated with the sale or purchase of portfolio
    securities in connection with a Reorganization).

12. GENERAL.

   a. Headings. The headings contained in this Agreement are for reference
      purposes only and will not affect the meaning or interpretation of this
      Agreement. Nothing in this Agreement is intended to confer upon any other

      Minnesota.

EXHIBIT B

MINNESOTA BUSINESS CORPORATION ACT SECTIONS 302A.471 AND 302A.473

Minnesota law requires that we provide you with a copy of the state law on
dissenters' rights. Notwithstanding the provisions of the law set out below, the
SEC has taken the position that use of state appraisal procedures by a
registered mutual fund such as RiverSource Partners Aggressive Growth Fund,
RiverSource Partners Select Value Fund, RiverSource Partners Small Cap Equity
Fund, RiverSource Partners Small Cap Growth Fund or RiverSource Tax-Exempt Money
Market Fund would be a violation of Rule 22c-1, the forward pricing rule, under
the 1940 Act. As a result, if any shareholder elects to exercise dissenters'
rights under Minnesota law, the Fund intends to submit this question to a court
of competent jurisdiction. In that event, a dissenting shareholder would not
receive any payment until the end of the court proceeding.

302A.471 RIGHTS OF DISSENTING SHAREHOLDERS.

SUBDIVISION 1. ACTIONS CREATING RIGHTS. A shareholder of a corporation may
dissent from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:

(a) unless otherwise provided in the articles, an amendment of the articles that
    materially and adversely affects the rights or preferences of the shares of
    the dissenting shareholder in that it:

  (1) alters or abolishes a preferential right of the shares;

  (2) creates, alters, or abolishes a right in respect of the redemption of the
      shares, including a provision respecting a sinking fund for the redemption
      or repurchase of the shares;

  (3) alters or abolishes a preemptive right of the holder of the shares to
      acquire shares, securities other than shares, or rights to purchase shares
      or securities other than shares;

  (4) excludes or limits the right of a shareholder to vote on a matter, or to
      cumulate votes, except as the right may be excluded or limited through the
      authorization or issuance of securities of an existing or new class or
      series with similar or different voting rights; except that an amendment
      to the articles of an issuing public corporation that provides that
      section 302A.671 does not apply to a control share acquisition does not
      give rise to the right to obtain payment under this section; or

  (5) eliminates the right to obtain payment under this subdivision;

(b) a sale, lease, transfer, or other disposition of property and assets of the
    corporation that requires shareholder approval under section 302A.661,
    subdivision 2, but not including a disposition in dissolution described in
    section 302A.725, subdivision 2, or a disposition pursuant to an order of a
    court, or a disposition for cash on terms requiring that all or
    substantially all of the net proceeds of disposition be distributed to the
    shareholders in accordance with their respective interests within one year
    after the date of disposition;

(c) a plan of merger, whether under this chapter or under chapter 322B, to which
    the corporation is a constituent organization, except as provided in
    subdivision 3, and except for a plan of merger adopted under section
    302A.626;

(d) a plan of exchange, whether under this chapter or under chapter 322B, to
    which the corporation is a party as the corporation whose shares will be
    acquired by the acquiring organization, except as provided in subdivision 3;

(e) a plan of conversion adopted by the corporation; or

(f) any other corporate action taken pursuant to a shareholder vote with respect
    to which the articles, the bylaws, or a resolution approved by the board
    directs that dissenting shareholders may obtain payment for their shares.

SUBD. 2. BENEFICIAL OWNERS.

(a) A shareholder shall not assert dissenters' rights as to less than all of the
    shares registered in the name of the shareholder, unless the shareholder
    dissents with respect to all the shares that are beneficially owned by
    another person but registered in the name of the shareholder and discloses
    the name and address of each beneficial owner on whose behalf the
    shareholder dissents. In that event, the rights of the dissenter shall be
    determined as if the shares as to which the shareholder has dissented and
    the other shares were registered in the names of different shareholders.

(b) A beneficial owner of shares who is not the shareholder may assert
    dissenters' rights with respect to shares held on behalf of the beneficial
    owner, and shall be treated as a dissenting shareholder under the terms of
    this section and section 302A.473, if the beneficial owner submits to the
    corporation at the time of or before the assertion of the rights a written
    consent of the shareholder.


                                       B.1



SUBD. 3. RIGHTS NOT TO APPLY.

(a) Unless the articles, the bylaws, or a resolution approved by the board
    otherwise provide, the right to obtain payment under this section does not
    apply to a shareholder of (1) the surviving corporation in a merger with
    respect to shares of the shareholder that are not entitled to be voted on
    the merger and are not canceled or exchanged in the merger or (2) the
    corporation whose shares will be acquired by the acquiring organization in a
    plan of exchange with respect to shares of the shareholder that are not
    entitled to be voted on the plan of exchange and are not exchanged in the
    plan of exchange.

(b) If a date is fixed according to section 302A.445, subdivision 1, for the
    determination of shareholders entitled to receive notice of and to vote on
    an action described in subdivision 1, only shareholders as of the date
    fixed, and beneficial owners as of the date fixed who hold through
    shareholders, as provided in subdivision 2, may exercise dissenters' rights.

(c) Notwithstanding subdivision 1, the right to obtain payment under this
    section, other than in connection with a plan of merger adopted under
    section 302A.621, is limited in accordance with the following provisions:

  (1) The right to obtain payment under this section is not available for the
      holders of shares of any class or series of shares that is listed on the
      New York Stock Exchange, the American Stock Exchange, the NASDAQ Global
      Market, or the NASDAQ Global Select Market.

  (2) The applicability of clause (1) is determined as of:

     (i)  the record date fixed to determine the shareholders entitled to
          receive notice of, and to vote at, the meeting of shareholders to act
          upon the corporate action described in subdivision 1; or

     (ii) the day before the effective date of corporate action described in
          subdivision 1 if there is no meeting of shareholders.

  (3) Clause (1) is not applicable, and the right to obtain payment under this
      section is available pursuant to subdivision 1, for the holders of any
      class or series of shares who are required by the terms of the corporate
      action described in subdivision 1 to accept for such shares anything other
      than shares, or cash in lieu of fractional shares, of any class or any
      series of shares of a domestic or foreign corporation, or any other
      ownership interest of any other organization, that satisfies the standards
      set forth in clause (1) at the time the corporate action becomes
      effective.

SUBD. 4. OTHER RIGHTS. The shareholders of a corporation who have a right under
this section to obtain payment for their shares, or who would have the right to
obtain payment for their shares absent the exception set forth in paragraph (c)
of subdivision 3, do not have a right at law or in equity to have a corporate
action described in subdivision 1 set aside or rescinded, except when the
corporate action is fraudulent with regard to the complaining shareholder or the
corporation.

    meanings given them.

SUBD. 2. NOTICE OF ACTION. If a corporation calls a shareholder meeting at which
any action described in section 302A.471, subdivision 1 is to be voted upon, the
notice of the meeting shall inform each shareholder of the right to dissent and
shall include a copy of section 302A.471 and this section and a brief
description of the procedure to be followed under these sections.

SUBD. 3. NOTICE OF DISSENT. If the proposed action must be approved by the
shareholders and the corporation holds a shareholder meeting, a shareholder who
is entitled to dissent under section 302A.471 and who wishes to exercise
dissenters' rights must file with the corporation before the vote on the
proposed action a written notice of intent to demand the fair value of the
shares owned by the shareholder and must not vote the shares in favor of the
proposed action.

SUBD. 4. NOTICE OF PROCEDURE; DEPOSIT OF SHARES.

(a) After the proposed action has been approved by the board and, if necessary,
    the shareholders, the corporation shall send to (i) all shareholders who
    have complied with subdivision 3, (ii) all shareholders who did not sign or
    consent to a written

                                       B.2



    action that gave effect to the action creating the right to obtain payment
    under section 302A.471, and (iii) all shareholders entitled to dissent if no
    shareholder vote was required, a notice that contains:

  (1) the address to which a demand for payment and certificates of certificated
      shares must be sent in order to obtain payment and the date by which they
      must be received;

  (2) any restrictions on transfer of uncertificated shares that will apply
      after the demand for payment is received;

  (3) a form to be used to certify the date on which the shareholder, or the
      beneficial owner on whose behalf the shareholder dissents, acquired the
      shares or an interest in them and to demand payment; and

  (4) a copy of section 302A.471 and this section and a brief description of the
      procedures to be followed under these sections.

(b) In order to receive the fair value of the shares, a dissenting shareholder
    must demand payment and deposit certificated shares or comply with any
    restrictions on transfer of uncertificated shares within 30 days after the
    notice required by paragraph (a) was given, but the dissenter retains all
    other rights of a shareholder until the proposed action takes effect.

SUBD. 5. PAYMENT; RETURN OF SHARES.

(a) After the corporate action takes effect, or after the corporation receives a
    valid demand for payment, whichever is later, the corporation shall remit to
    each dissenting shareholder who has complied with subdivisions 3 and 4 the
    amount the corporation estimates to be the fair value of the shares, plus
    interest, accompanied by:

  (1) the corporation's closing balance sheet and statement of income for a
      fiscal year ending not more than 16 months before the effective date of
      the corporate action, together with the latest available interim financial
      statements;

  (2) an estimate by the corporation of the fair value of the shares and a brief
      description of the method used to reach the estimate; and

  (3) a copy of section 302A.471 and this section, and a brief description of
      the procedure to be followed in demanding supplemental payment.

(b) The corporation may withhold the remittance described in paragraph (a) from
    a person who was not a shareholder on the date the action dissented from was
    first announced to the public or who is dissenting on behalf of a person who
    was not a beneficial owner on that date. If the dissenter has complied with
    subdivisions 3 and 4, the corporation shall forward to the dissenter the
    materials described in paragraph (a), a statement of the reason for
    withholding the remittance, and an offer to pay to the dissenter the amount
    listed in the materials if the dissenter agrees to accept that amount in
    full satisfaction. The dissenter may decline the offer and demand payment
    under subdivision 6. Failure to do so entitles the dissenter only to the
    amount offered. If the dissenter makes demand, subdivisions 7 and 8 apply.

(c) If the corporation fails to remit payment within 60 days of the deposit of
    certificates or the imposition of transfer restrictions on uncertificated
    shares, it shall return all deposited certificates and cancel all transfer
    restrictions. However, the corporation may again give notice under
    subdivision 4 and require deposit or restrict transfer at a later time.

SUBD. 6. SUPPLEMENTAL PAYMENT; DEMAND. If a dissenter believes that the amount
remitted under subdivision 5 is less than the fair value of the shares plus
interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.

SUBD. 7. PETITION; DETERMINATION. If the corporation receives a demand under
subdivision 6, it shall, within 60 days after receiving the demand, either pay
to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest. The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located. The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation. The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
Rules of Civil Procedure. Nonresidents of this state may be served by registered
or certified mail or by publication as provided by law. Except as otherwise
provided, the Rules of Civil Procedure apply to this proceeding. The
jurisdiction of the court is plenary and exclusive. The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares. The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter. The fair value of the

                                       B.3



shares as determined by the court is binding on all shareholders, wherever
located. A dissenter is entitled to judgment in cash for the amount by which the
fair value of the shares as determined by the court, plus interest, exceeds the
amount, if any, remitted under subdivision 5, but shall not be liable to the
corporation for the amount, if any, by which the amount, if any, remitted to the
dissenter under subdivision 5 exceeds the fair value of the shares as determined
by the court, plus interest.

SUBD. 8. COSTS; FEES; EXPENSES.

(a) The court shall determine the costs and expenses of a proceeding under
    subdivision 7, including the reasonable expenses and compensation of any
    appraisers appointed by the court, and shall assess those costs and expenses
    against the corporation, except that the court may assess part or all of
    those costs and expenses against a dissenter whose action in demanding
    payment under subdivision 6 is found to be arbitrary, vexatious, or not in
    good faith.

(b) If the court finds that the corporation has failed to comply substantially
    with this section, the court may assess all fees and expenses of any experts
    or attorneys as the court deems equitable. These fees and expenses may also
    be assessed against a person who has acted arbitrarily, vexatiously, or not
    in good faith in bringing the proceeding, and may be awarded to a party
    injured by those actions.

(c) The court may award, in its discretion, fees and expenses to an attorney for
    the dissenters out of the amount awarded to the dissenters, if any.


                                       B.4



EXHIBIT C

ADDITIONAL INFORMATION APPLICABLE TO THE BUYING FUNDS

Below is information regarding the Buying Funds. All references to a Fund or the
Funds refer to a Buying Fund or the Buying Funds respectively unless otherwise
noted.

Other Investment Strategies. In addition to the principal investment strategies
previously described for RiverSource Mid Cap Growth Fund, RiverSource Mid Cap
Value Fund and RiverSource Partners International Small Cap Fund, Seligman
Frontier Fund and Seligman Smaller-Cap Value Fund each Buying Fund may utilize
investment strategies that are not principal investment strategies, including
investment in affiliated and non-affiliated pooled investment vehicles
(including mutual funds and exchange traded funds (ETFs), also referred to as
"acquired funds") ownership of which results in the Fund bearing its
proportionate share of the acquired funds' fees and expenses and proportionate
exposure to the risks associated with acquired funds' underlying investments.
ETFs are generally designed to replicate the price and yield of a specified
market index. An ETF's share price may not track its specified market index and
may trade below its net asset value, resulting in a loss. ETFs generally use a
"passive" investment strategy and will not attempt to take defensive positions
in volatile or declining markets. An active secondary market in an ETF's shares
may not develop or be maintained and may be halted or interrupted due to actions
by its listing exchange, unusual market conditions or other reasons. There can
be no assurance an ETF's shares will continue to be listed on an active
exchange.

Additionally, for RiverSource Mid Cap Growth Fund, RiverSource Mid Cap Value
Fund and Seligman Smaller-Cap Value Fund, each Buying Fund may use derivatives
such as futures, options, forward contracts, and swaps (which are financial
instruments that have a value which depends upon, or is derived from, the value
of something else, such as one or more underlying securities, pools of
securities, indexes or currencies). These derivative instruments are used to
produce incremental earnings, to hedge existing positions, to increase or reduce
market or credit exposure, or to increase flexibility. Derivative instruments
will typically increase the Fund's exposure to the principal risks to which it
is otherwise exposed, and may expose the Fund to additional risks, including
counterparty credit risk, leverage risk, hedging risk, correlation risk, and
liquidity risk. Counterparty credit risk is the risk that a counterparty to the
derivative instrument becomes bankrupt or otherwise fails to perform its
obligations due to financial difficulties, and the Fund may obtain no recovery
of its investment or may only obtain a limited recovery, and any recovery may be
delayed. Hedging risk is the risk that derivative instruments used to hedge
against an opposite position, may offset losses, but they may also offset gains.
There is no guarantee that a hedging strategy will eliminate the risk which the
hedging strategy is intended to offset, which may lead to losses within the
Fund. Correlation risk is related to hedging risk and is the risk that there may
be an incomplete correlation between the hedge and the opposite position, which
may result in increased or unanticipated losses. Liquidity risk is the risk that
the derivative instrument may be difficult or impossible to sell or terminate,
which may cause the Fund to be in a position to do something the investment
manager would not otherwise choose, including, accepting a lower price for the
derivative instrument, selling other investments, or foregoing another, more
appealing investment opportunity. Derivative instruments which are not traded on
an exchange, including, but not limited to, forward contracts, swaps and over-
the-counter options, may have increased liquidity risk. Leverage risk is the
risk that losses from the derivative instrument may be greater than the amount
invested in the derivative instrument. In addition, a relatively small price
movement in the underlying security, currency or index may result in a
substantial loss for the Fund using derivatives and certain derivatives have the
potential for unlimited losses, regardless of the size of the initial
investment. Even though the Fund's policies permit the use of derivatives in
this manner, the portfolio managers are not required to use derivatives.

In addition to the principal investment strategies previously described for
RiverSource Government Money Market Fund, the Fund may invest in other
securities and may use other investment strategies that are not principal
investment strategies.

For more information on strategies and holdings, and the risks of such
strategies, including derivative instruments that the Buying Funds may use, see
the Fund's Merger SAI and its annual and semiannual reports.

For RiverSource Mid Cap Growth Fund, RiverSource Mid Cap Value Fund, RiverSource
Partners International Small Cap Fund, Seligman Frontier Fund and Seligman
Smaller-Cap Value Fund:

Unusual Market Conditions. During unusual market conditions, the Fund may
temporarily invest more of its assets in money market securities than during
normal market conditions. Although investing in these securities would serve
primarily to attempt to avoid losses, this type of investing also could prevent
the Fund from achieving its investment objective. During these times, the
portfolio managers may make frequent securities trades that could result in
increased fees, expenses and taxes, and decreased performance. Instead of
investing in money market securities directly, the Fund may invest in shares of
an affiliated or unaffiliated money market fund. See "Cash Reserves" under the
section "General Information" for more information.


                                       C.1



For RiverSource Mid Cap Growth Fund, RiverSource Mid Cap Value Fund, RiverSource
Partners International Small Cap Fund, Seligman Frontier Fund and Seligman
Smaller-Cap Value Fund:

Securities Transaction Commissions. Securities transactions involve the payment
by the Fund of brokerage commissions to broker-dealers, on occasion as
compensation for research or brokerage services (commonly referred to as "soft
dollars"), as the portfolio managers buy and sell securities for the Fund in
pursuit of its objective. A description of the policies governing the Fund's
securities transactions and the dollar value of brokerage commissions paid by
the Fund are set forth in the Merger SAI. The brokerage commissions set forth in
the Merger SAI do not include implied commissions or mark-ups (implied
commissions) paid by the Fund for principal transactions (transactions made
directly with a dealer or other counterparty), including most fixed income
securities (and certain other instruments, including derivatives). Brokerage
commissions do not reflect other elements of transaction costs, including the
extent to which the Fund's purchase and sale transactions may cause the market
to move and change the market price for an investment. Fixed-income securities
are generally traded on the over-the-counter market on a "net" basis without a
stated commission, through dealers acting for their own account and not as
brokers. Prices paid to dealers will generally include a "spread," i.e., the
difference between the prices at which a dealer is willing to purchase or to
sell the security at that time.

Although brokerage commissions and implied commissions are not reflected in the
expense table under "Fees and Expenses of the Fund," they are reflected in the
total return of the Fund.

For RiverSource Government Money Market Fund, RiverSource Mid Cap Growth Fund,
RiverSource Mid Cap Value Fund, RiverSource Partners International Small Cap
Fund, Seligman Frontier Fund and Seligman Smaller-Cap Value Fund:

Directed Brokerage. The Fund's Board has adopted a policy prohibiting the
investment manager, or any subadviser, from considering sales of shares of the
Fund as a factor in the selection of broker-dealers through which to execute
securities transactions.

Additional information regarding securities transactions can be found in the
Merger SAI.

For RiverSource Government Money Market Fund, RiverSource Mid Cap Growth Fund,
RiverSource Mid Cap Value Fund, RiverSource Partners International Small Cap
Fund, Seligman Frontier Fund and Seligman Smaller-Cap Value Fund:

Financial Intermediary Compensation. If you purchase shares of the Fund through
a broker-dealer or other financial intermediary (such as a bank), the Fund and
its related companies may pay the financial intermediary for the sale of Fund
shares and related services. These payments may create a conflict of interest by
influencing the broker-dealer or other financial intermediary to recommend the
Fund over another investment. Ask your financial intermediary, or visit their
website for more information.

FUND MANAGEMENT AND COMPENSATION (FOR ALL BUYING FUNDS)

INVESTMENT MANAGER

RiverSource Investments, 200 Ameriprise Financial Center, Minneapolis, Minnesota
55474, is the investment manager to the RiverSource Family of Funds (including
the RiverSource funds, Threadneedle funds and Seligman funds), and is a wholly-
owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial).
Ameriprise Financial is a financial planning and financial services company that
has been offering solutions for clients' asset accumulation, income management
and protection needs for more than 110 years. In addition to managing
investments for the RiverSource Family of Funds, RiverSource Investments manages
investments for itself and its affiliates. For institutional clients,
RiverSource Investments and its affiliates provide investment management and
related services, such as separate account asset management, and institutional
trust and custody, as well as other investment products. For all of its clients,
RiverSource Investments seeks to allocate investment opportunities in an
equitable manner over time. See the Merger SAI for more information.

On November 7, 2008, RiverSource Investments completed the acquisition (the
"Acquisition") of J. & W. Seligman & Co. Incorporated (Seligman), 100 Park
Avenue, New York, New York 10017. With the Acquisition completed and Seligman
Funds' shareholders having previously approved (at a special meeting held on
Nov. 3, 2008) new Investment Management Services Agreements ("IMS Agreements")
between Seligman Funds and RiverSource Investments, RiverSource Investments
became the new investment manager for Seligman Funds, including RiverSource
Government Money Market Fund (Seligman Cash Management Fund prior to Sept. 28,
2009), Seligman Frontier Fund and Seligman Smaller-Cap Value Fund.

The RiverSource Family of Funds has received an order from the Securities and
Exchange Commission that permits RiverSource Investments, subject to the
approval of the Board, to appoint a subadviser or change the terms of a
subadvisory agreement for a fund without first obtaining shareholder approval.
The order permits the fund to add or change unaffiliated subadvisers or change
the fees paid to subadvisers from time to time without the expense and delays
associated with obtaining shareholder approval of the change. If RiverSource
Government Money Market Fund, Seligman Frontier Fund, or Seligman Smaller-Cap
Value Fund were to seek to rely on the order, holders of a majority of the
fund's outstanding voting securities

                                       C.2



would need to approve operating the Fund in this manner. There is no assurance
shareholder approval, if sought, would be received, and no changes will be made
without shareholder approval until that time.

RiverSource Investments or its affiliates may have other relationships,
including significant financial relationships, with current or potential
subadvisers or their affiliates, which may create a conflict of interest. In
making recommendations to the Board to appoint or to change a subadviser, or to
change the terms of a subadvisory agreement, RiverSource Investments does not
consider any other relationship it or its affiliates may have with a subadviser,
and RiverSource Investments discloses the nature of any material relationships
it has with a subadviser to the Board.

The Fund pays RiverSource Investments a fee for managing its assets. Under the
Investment Management Services Agreements, the fee for the most recent fiscal
year was the following percentage of the Buying Fund's average daily net assets:

RiverSource Mid Cap Value Fund                                                     0.57%

 *  The investment management services fee paid by each Fund is equal to the
    aggregate amount paid by the Fund during the last fiscal year to RiverSource
    Investments (since Nov. 7, 2008) and to Seligman (prior to Nov. 7, 2008).
    For RiverSource Government Money Market Fund, effective June 15, 2009, the
    annual management fee rate is equal to a percentage of the Fund's average
    daily net assets with such rate declining from 0.33% to 0.15% as the Fund's
    net assets increase. Prior to Nov. 7, 2008, for RiverSource Government Money
    Market Fund, the annual management fee rate was equal to a percentage of the
    Fund's average daily net assets with such rate declining from 0.42% to
    0.375% as the Fund's net assets increased; from Nov. 7, 2008 to June 14,
    2009, for RiverSource Government Money Market Fund, the annual management
    fee rate was 0.40% of the Fund's average daily net assets. For Seligman
    Frontier Fund, effective June 29, 2009, the annual management fee rate is
    equal to a percentage of the Fund's average daily net assets, with such rate
    declining from 0.885% to 0.790% as the Fund's net assets increase. Prior to
    June 29, 2009, for Seligman Frontier Fund, the annual management fee rate
    was equal to a percentage of the Fund's average daily net assets, with such
    rate declining from 0.95% to 0.85% as the Fund's net assets increased. For
    Seligman Smaller-Cap Value Fund, effective June 29, 2009, the annual
    management fee rate is equal to a percentage of the Fund's average daily net
    assets, with such rate declining from 0.935% to 0.745% as the Fund's net
    assets increase. Prior to June 29, 2009, for Seligman Smaller-Cap Value
    Fund, the annual management fee rate was equal to 1.00% of the Fund's
    average daily net assets.

The reduction in the investment management services fee schedule is related
primarily to the elimination of the administrative portion of the management fee
that is now being charged separately to the Fund through the Administrative
Services Agreement with Ameriprise Financial. Under the Administrative Services
Agreement, effective June 15, 2009, RiverSource Government Money Market Fund
pays Ameriprise Financial an annual fee for administrative and accounting
services equal to a percentage of the Fund's average daily net assets that
declines from 0.06% to 0.03% as the Fund's net assets increase, effective June
29, 2009, each of Seligman Frontier Fund and Seligman Smaller-Cap Value Fund
pays Ameriprise Financial an annual fee for administrative and accounting
services equal to a percentage of the Fund's average daily net assets that
declines from 0.08% to 0.05%, as the Fund's net assets increase.

For RiverSource Mid Cap Growth Fund, RiverSource Mid Cap Value Fund and
RiverSource Partners International Small Cap Fund, the fee includes an
adjustment under the terms of a performance incentive arrangement. The
adjustment is computed by comparing the Fund's performance to the performance of
an index of comparable funds published by Lipper Inc. The index against which
the Fund's performance is currently measured for purposes of the performance
incentive adjustment is the Lipper Mid-Cap Growth Funds Index for RiverSource
Mid Cap Growth Fund, the Lipper Mid-Cap Value Funds Index for RiverSource Mid
Cap Value Fund and the Lipper International Small-Cap Funds Index for
RiverSource Partners International Small Cap Fund. In certain circumstances, the
Fund's Board may approve a change in the index without shareholder approval. The
maximum adjustment (increase or decrease) is 0.12% of the Fund's average net
assets on an annual basis.

Under the IMS Agreement, the Fund also pays taxes, brokerage commissions, and
nonadvisory expenses. For RiverSource Mid Cap Growth Fund, RiverSource Mid Cap
Value Fund and RiverSource Partners International Small Cap Fund, a discussion
regarding the basis for the Board approving the IMS Agreement is available in
the Fund's most recent annual or semiannual shareholder report. For RiverSource
Government Money Market Fund, Seligman Frontier Fund and Seligman Smaller-Cap
Value Fund, a discussion regarding the basis for the Board approving the IMS
Agreement was included in the Funds' proxy statement, dated Aug. 27, 2008, and
is available in the Fund's annual shareholder report for the year ended Dec. 31,
2008 for RiverSource Government Money Market Fund and Seligman Smaller-Cap Value
Fund and for the year ended Oct. 31, 2008 for Seligman Frontier Fund.

RIVERSOURCE FAMILY OF FUNDS

THE RIVERSOURCE FAMILY OF FUNDS (EACH INDIVIDUALLY A "FUND" AND, COLLECTIVELY,
THE "FUNDS") INCLUDES "RIVERSOURCE" FUNDS, "RIVERSOURCE PARTNERS" FUNDS,
"SELIGMAN" FUNDS AND "THREADNEEDLE" FUNDS. (THE RIVERSOURCE FUNDS, RIVERSOURCE
PARTNERS FUNDS AND THREADNEEDLE FUNDS MAY BE COLLECTIVELY REFERRED TO AS THE
"RIVERSOURCE FUNDS".) THE FUNDS SHARE THE SAME BOARD OF DIRECTORS/TRUSTEES (THE
"BOARD") AND THE SAME POLICIES AND PROCEDURES INCLUDING THOSE SET FORTH IN THE
SERVICE SECTION OF THIS PROSPECTUS. FOR EXAMPLE, FOR PURPOSES OF CALCULATING THE
INITIAL SALES CHARGE ON THE PURCHASE OF CLASS A SHARES OF A FUND, AN INVESTOR OR
FINANCIAL ADVISOR SHOULD CONSIDER THE COMBINED MARKET VALUE OF ALL FUNDS IN THE
RIVERSOURCE FAMILY OF FUNDS OWNED BY THE INVESTOR AS DEFINED UNDER "INITIAL
SALES CHARGE -- RIGHTS OF ACCUMULATION (ROA)."

BUYING AND SELLING SHARES

The funds are available directly and through broker-dealers, banks and other
financial intermediaries or institutions (financial intermediaries), and through
certain qualified and non-qualified plans, wrap fee products or other investment
products sponsored by financial intermediaries. NOT ALL FINANCIAL INTERMEDIARIES
OFFER THE FUNDS. FINANCIAL INTERMEDIARIES THAT OFFER THE FUNDS MAY CHARGE YOU
ADDITIONAL FEES FOR THE SERVICES THEY PROVIDE AND THEY MAY HAVE DIFFERENT
POLICIES NOT DESCRIBED IN THIS PROSPECTUS. Some policy differences may include
different minimum investment amounts, exchange privileges, fund choices and
cutoff times for investments. Additionally, recordkeeping, transaction
processing and payments of distributions relating to your account may be
performed by the financial intermediaries through which your shares of the fund
are held. Since the fund (and its service providers) may not have a record of
your account transactions, you should always contact the financial intermediary
through which you purchased or at which you maintain your shares of the fund to
make changes to your account or to give instructions concerning your account, or
to obtain information about your account. The fund and its service providers,
including the distributor and the transfer agent, are not responsible for the
failure of one of these financial intermediaries to carry out its obligations to
its customers.

DESCRIPTION OF SHARE CLASSES

INVESTMENT OPTIONS -- CLASSES OF SHARES

The funds offer different classes of shares. There are differences among the
fees and expenses for each share class. See the "Fees and Expenses" table for
more information. Not everyone is eligible to buy every share class. After
determining which share classes you are eligible to buy, decide which share
class best suits your needs. Your financial advisor can help you with this
decision. The following table shows the key features of each share class. Not
all funds offer all classes of shares.

(a) See "Buying and Selling Shares, Determining which class of shares to
    purchase" for more information on availability of share classes and eligible
    investors. See "Buying and Selling Shares, Opening an Account" for
    information on minimum investment and account balance requirements.
(b) For each of Class A, Class B, Class C, Class R2, Class R3 and Class W
    shares, as applicable, each fund has adopted a plan under Rule 12b-1 of the
    Investment Company Act of 1940, as amended, that allows it to pay
    distribution and shareholder servicing-related expenses for the sale of
    shares and the servicing of shareholders. This plan has been reviewed and
    approved by the Board. Because these fees are paid out of fund assets on an
    on-going basis, over time these fees will increase the cost of your
    investment and may cost you more than paying other types of distribution
    (sales) or servicing charges.
(c) A 1% CDSC may be assessed on Class A shares sold within 18 months after
    purchase. See "Buying and Selling Shares, Sales Charges, Class
    A -- contingent deferred sales charge" for more information. For all funds
    except money market funds.
(d) Class B shares automatically convert to Class A shares. See "Buying and
    Selling Shares, Sales Charges, Class B and Class C -- CDSC alternative" for
    more information on the timing of conversion of Class B shares to Class A
    shares. Timing of conversion will vary depending on the date of your
    original purchase of the Class B shares.
(e) Class B shares of RiverSource Absolute Return Currency and Income Fund are
    only available for exchanges from Class B shares of another fund in the
    RiverSource Family of Funds. Class B shares of each of RiverSource Floating
    Rate Fund, RiverSource Inflation Protected Securities Fund, RiverSource
    Intermediate Tax-Exempt Fund, RiverSource Limited Duration Bond Fund and
    RiverSource Short Duration U.S. Government Fund are closed to new investors
    and new purchases. (Existing shareholders in these funds may continue to own
    Class B shares and make exchanges into and out of existing accounts where
    Class B shares of these funds are maintained.)
(f) The money market funds may offer Class B and Class C shares, but only to
    facilitate exchanges with other funds offering Class B and Class C shares,
    respectively.

DISTRIBUTION AND SERVICE FEES

The distribution and shareholder servicing fees for Class A, Class B, Class C,
Class R2, Class R3 and Class W shares, as applicable, are subject to the
requirements of Rule 12b-1 under the Investment Company Act of 1940, as amended,
and are used to reimburse the distributor for certain expenses it incurs in
connection with distributing the fund's shares and directly or indirectly
providing services to fund shareholders. These expenses include payment of
distribution and/or shareholder servicing fees to financial intermediaries that
sell shares of the fund or provide services to fund shareholders, up to 0.50% of
the average daily net assets of Class R2 shares sold and held through them and
up to 0.25%* of the average daily net assets of Class A, Class B, Class C, Class
R3 and Class W shares sold and held through them. For Class A, Class B, Class
R2, Class R3 and Class W shares, the distributor begins to pay these fees
immediately after purchase. For Class C shares, the distributor pays these fees
in advance for the first 12 months. Financial intermediaries also receive
distribution fees up to 0.75% of the average daily net assets of Class C shares
sold and held through them, which the distributor begins to pay 12 months after
purchase. For Class B shares, and, for the first 12 months following the sale of
Class C shares, the fund's distributor retains the distribution fee of up to
0.75% in order to finance the payment of sales commissions to financial
intermediaries, and to pay for other distribution related expenses. Financial
intermediaries may compensate their financial advisors with the shareholder
servicing and distribution fees paid to them by the distributor. IF YOU MAINTAIN
SHARES OF THE FUND DIRECTLY WITH THE FUND, WITHOUT WORKING DIRECTLY WITH A
FINANCIAL INTERMEDIARY OR FINANCIAL ADVISOR, DISTRIBUTION AND SERVICE FEES MAY
BE RETAINED BY THE DISTRIBUTOR AS REIMBURSEMENT FOR INCURRING CERTAIN
DISTRIBUTION AND SHAREHOLDER SERVICING RELATED EXPENSES.

 *  For RiverSource Cash Management Fund, financial intermediaries receive fees
    up to 0.10% of the average daily net assets of Class A, Class B and Class W
    shares sold and held through them.

PLAN ADMINISTRATION FEE

Class R2, Class R3, Class R4 and Class Y shares pay an annual plan
administration services fee for the provision of various administrative,
recordkeeping, communication and educational services. The fee for Class R2,
Class R3 and Class R4 shares is equal on an annual basis to 0.25% of average
daily net assets attributable to the respective class. The fee for Class Y
shares is equal on an annual basis to 0.15% of average daily net assets
attributable to the class.


                                       C.8



DETERMINING WHICH CLASS OF SHARES TO PURCHASE

Each of the fund's classes represent an interest in the same portfolio of
investments. However, as set forth above, each class has its own sales charge
schedule, and its ongoing distribution and shareholder service fees may differ
from other classes. When deciding which class of shares to buy, you should
consider, among other things:

- The amount you plan to invest.

- How long you intend to remain invested in the fund or another fund in the
  RiverSource Family of Funds.

- Whether you may be eligible for reduced or no sales charges when you buy or
  sell shares.

Your authorized financial intermediary or financial advisor will be able to help
you decide which class of shares best meets your needs.

CLASS A, CLASS B AND CLASS C SHARES*

Class B shares of RiverSource Absolute Return Currency and Income Fund are not
currently available for new purchases. However, if you own Class B shares of
another fund in the RiverSource Family of Funds, you may exchange into Class B
shares of RiverSource Absolute Return Currency and Income Fund, if you meet the
minimum investment and account balance requirements set forth in "Opening an
Account," subject to the limitations set forth in this section. New purchases of
Class B shares will not be permitted if your rights of accumulation are $50,000
or higher, and new purchases of Class C shares will not be permitted if your
rights of accumulation are $1,000,000 or higher. See "Sales Charges, Initial
Sales Charge -- Rights of Accumulation" for information on rights of
accumulation.

Class B shares have a higher annual distribution fee than Class A shares and a
contingent deferred sales charge (CDSC) for six years. Class B shares convert to
Class A shares. Class B shares purchased through reinvested dividends and
distributions will convert to Class A shares in the same proportion as the other
Class B shares. See "Class B and Class C -- CDSC alternative" for information on
timing of Class B share conversion to Class A shares.

Class C shares have a higher annual distribution fee than Class A shares and a
CDSC for one year. Class C shares have no sales charge if you hold the shares
for longer than one year. Unlike Class B shares, Class C shares do not convert
to Class A shares. As a result, you will pay a distribution fee for as long as
you hold Class C shares.

If you choose a share class with a CDSC (Class B or Class C), you should
consider the length of time you intend to hold your shares. To help you
determine which investment is best for you, consult your financial intermediary
or financial advisor.

 *  For money market funds, new investments must be made in Class A shares of
    the fund. The money market funds offer Class B and Class C shares only to
    facilitate exchanges between classes of these shares in other funds.

CLASS I SHARES.

The following eligible investors may purchase Class I shares:

- Any fund distributed by the distributor, if the fund seeks to achieve its
  investment objective by investing primarily in shares of funds in the
  RiverSource Family of Funds.

Class I shares may be purchased, sold or exchanged only through the distributor
or an authorized financial intermediary.

CLASS R AND CLASS Y SHARES.

The following eligible institutional investors may purchase Class R2, Class R3,
Class R4, Class R5 and Class Y shares:

- Qualified employee benefit plans.

- Trust companies or similar institutions, and charitable organizations that
  meet the definition in Section 501(c)(3) of the Internal Revenue Code.

- Non-qualified deferred compensation plans whose participants are included in a
  qualified employee benefit plan described above.

- State sponsored college savings plans established under Section 529 of the
  Internal Revenue Code.

- Health Savings Accounts created pursuant to public law 108-173.

Additionally, if approved by the distributor, the following eligible
institutional investors may purchase Class R5 shares:

- Institutional or corporate accounts above a threshold established by the
  distributor (currently $1 million per fund or $10 million in all funds in the
  RiverSource Family of Funds).

- Bank trust departments.

Class R and Class Y shares generally are not available to retail non-retirement
accounts, traditional and Roth IRAs, Coverdell Educational Savings Accounts,
SEPs, SARSEPs, SIMPLE IRAs and individual 403(b) plans.


                                       C.9



Class R shares may be purchased, sold or exchanged only through the distributor
or an authorized financial intermediary.

CLASS W SHARES.

The following eligible investors may purchase Class W shares:

- Investors purchasing through authorized investment programs managed by
  investment professionals, including discretionary managed account programs.

Class W shares may be purchased, sold or exchanged only through the distributor
or an authorized financial intermediary.

Shares originally purchased in a discretionary managed account may continue to
be held in Class W outside of a discretionary managed account, but no additional
Class W purchases may be made and no exchanges to Class W shares of another fund
may be made outside of a discretionary managed account.

IN ADDITION, FOR CLASS I, CLASS R, CLASS W AND CLASS Y SHARES, THE DISTRIBUTOR,
IN ITS SOLE DISCRETION, MAY ACCEPT OR AUTHORIZE FINANCIAL INTERMEDIARIES TO
ACCEPT INVESTMENTS FROM OTHER PURCHASERS NOT LISTED ABOVE.

Please consult your financial advisor for assistance in selecting the
appropriate class of shares. For more information, see the SAI.

SALES CHARGES

FOR FUNDS OTHER THAN MONEY MARKET FUNDS

CLASS A -- INITIAL SALES CHARGE ALTERNATIVE:

Your purchase price for Class A shares is generally the net asset value (NAV)
plus a front-end sales charge. The distributor receives the sales charge and re-
allows a portion of the sales charge to the financial intermediary through which
you purchased the shares. The distributor retains the balance of the sales
charge. The distributor retains the full sales charge you pay when you purchase
shares of the fund directly from the fund (not through an authorized financial
intermediary). Sales charges vary depending on the amount of your purchase.

(a) Because of rounding in the calculation of the offering price, the portion of
    the sales charge retained by the distributor may vary and the actual sales
    charge you pay may be more or less than the sales charge calculated using
    these percentages.
(b) Purchase price includes the sales charge.
(c) Although there is no sales charge for purchases with a total market value
    over $1,000,000, and therefore no re-allowance, the distributor may pay a
    financial intermediary the following out of its own resources: a sales
    commission of up to 1.00% for a sale of $1,000,000 to $3,999,999; a sales
    commission up to 0.50% for a sale of $4,000,000 to $49,999,999; and a sales
    commission up to 0.25% for a sale of $50,000,000 or more.
(d) For certain eligible employee benefit plans defined under section 401(a),
    401(k), 457 and 403(b) which meet eligibility rules for the waiver of
    applicable sales charges, the distributor may pay the following out of its
    own resources: a sales commission of 1.00% for a sale of $1 to $3,999,999
    received in eligible employee benefit plans; a sales commission up to 0.50%
    for a sale of $4,000,000 to $49,999,999; and a sales commission up to 0.25%
    for a sale of $50,000,000 or more. See "Initial Sales Charge -- Waivers of
    the sales charge for Class A shares" for employee benefit plan eligibility
    rules.

There is no initial sales charge on reinvested dividends or capital gain
distributions.

INITIAL SALES CHARGE -- RIGHTS OF ACCUMULATION (ROA). You may be able to reduce
the sales charge on Class A shares, based on the combined market value of
accounts in your ROA group. Your ROA group includes the current market values of
the following investments which are eligible to be added together for purposes
of determining the sales charge on your next purchase:

- Your current investment in a fund; and

- Previous investments you and members of your household have made in Class A,
  Class B or Class C shares in the fund and other funds in the RiverSource
  Family of Funds, provided your investment was subject to a sales charge. Your
  household consists of you, your spouse or domestic partner and your unmarried
  children under age 21, all of whom share a mailing address.

The following accounts are eligible to be included in your ROA group in order to
determine the sales charge on your purchase:

- Individual or joint accounts;

- Roth and traditional IRAs, SEPs, SIMPLEs and TSCAs, provided they are invested
  in Class A, Class B or Class C shares that were subject to a sales charge;

- UGMA/UTMA accounts for which you, your spouse, or your domestic partner is
  parent or guardian of the minor child;

- Revocable trust accounts for which you or a member of your household,
  individually, is the beneficial owner/grantor;

- Accounts held in the name of your, your spouse's, or your domestic partner's
  sole proprietorship or single owner limited liability company or S
  corporation; and

- Qualified retirement plan assets, provided that you are the sole owner of the
  business sponsoring the plan, are the sole participant (other than a spouse)
  in the plan, and have no intention of adding participants to the plan.

The following accounts are NOT eligible to be included in your ROA group in
order to determine the sales charge on your purchase:

- Accounts of pension and retirement plans with multiple participants, such as
  401(k) plans (which are combined to reduce the sales charge for the entire
  pension or retirement plan and therefore are not used to reduce the sales
  charge for your individual accounts);

- Investments in Class A shares where the sales charge is waived, for example,
  purchases through wrap accounts;


                                      C.11



- Investments in Class I, Class R2, Class R3, Class R4, Class R5, Class W or
  Class Y shares;

- Investments in 529 plans, donor advised funds, variable annuities, variable
  life insurance products, wrap accounts or managed separate accounts; and

- Charitable and irrevocable trust accounts.

If you purchase fund shares through different financial intermediaries, and you
want to include those assets toward a reduced sales charge, you must inform your
financial intermediary in writing about the other accounts when placing your
purchase order. Contact your financial intermediary to determine what
information is required.

Unless you provide your financial intermediary in writing with information about
all of the accounts that may count toward a sales charge reduction, there can be
no assurance that you will receive all of the reductions for which you may be
eligible. You should request that your financial intermediary provide this
information to the fund when placing your purchase order.

For more information on ROA, please see the SAI.

INITIAL SALES CHARGE -- LETTER OF INTENT (LOI). Generally, if you intend to
invest $50,000 or more (including any existing ROA) over a period of up to 13
months, you may be able to reduce the front-end sales charge(s) for investments
in Class A shares by completing and filing an LOI. The required form of LOI may
vary by financial intermediary. Existing ROA can be included in your LOI. Each
purchase of fund shares normally subject to an initial sales charge made during
the 13-month period will be made at the public offering price applicable to a
single transaction of the total dollar amount indicated by the LOI. Five percent
of the commitment amount will be placed in escrow. At the end of the 13-month
period, the LOI will end and the shares will be released from escrow. If you do
not invest the commitment amount by the end of the 13 months, the remaining
amount of the unpaid sales charge will be redeemed from the escrowed shares and
the remaining balance released from escrow.

Existing ROA Example. Shareholder currently has $60,000 ROA in the funds.
Shareholder completes an LOI to invest $100,000 in the funds (ROA eligible
accounts). Shareholder only needs to invest an additional $40,000 in the funds'
Class A shares (any non-money market fund in the RiverSource Family of Funds) in
order to fulfill the LOI commitment and receive reduced front-end sales
charge(s) over the next 13 months.

Notification Obligation. You must request the reduced sales charge when you buy
shares. If you do not complete and file an LOI, or do not request the reduced
sales charge at the time of purchase, you will not be eligible for the reduced
sales charge. You should request that your financial intermediary provide this
information to the fund when placing your purchase order. For more detail on
LOIs, please contact your financial intermediary or see the SAI.

  401(k), 457 and 403(b) which:

  - have at least $1 million in plan assets at the time of investment; and

  - have a plan level or omnibus account that is maintained with the fund or its
    transfer agent; and

  - transact directly with the fund or its transfer agent through a third party
    administrator or third party recordkeeper.

For more information regarding waivers of sales charge for Class A purchases,
please see the SAI.

The distributor may, in its sole discretion, authorize the waiver of sales
charges for additional classes of investors. Policies related to reducing or
waiving the sales charge may be modified or withdrawn at any time.

Unless you provide your financial intermediary with information in writing about
all of the factors that may count toward a waiver of the sales charge, there can
be no assurance that you will receive all of the waivers for which you may be
eligible. You should request that your financial intermediary provide this
information to the fund when placing your purchase order.

Because the current prospectus is available on the funds' website (for
RiverSource funds) at riversource.com/funds or (for Seligman funds) at
seligman.com free of charge, information regarding breakpoint discounts is not
separately disclosed on the website.

CDSCS AND THE COMBINATION OF TARGET DATE FUNDS WITH SELIGMAN TARGETFUND CORE

Each of Seligman TargETFund 2045, Seligman TargETFund 2035, Seligman TargETFund
2025 and Seligman TargETFund 2015 (the Target Date Funds) will automatically be
combined with Seligman TargETFund Core during their respective target year. The
investment manager expects each of these combinations to be effected as an
acquisition of the assets and liabilities of the applicable Target Date Fund in
exchange for shares of Seligman TargETFund Core at net asset value, with the
shares of Seligman TargETFund Core then distributed to shareholders of the
applicable Target Date Fund. For the purpose of calculating CDSCs, holding
periods in respect of shares of a Target Date Fund will be carried over to
shares of Seligman TargETFund Core acquired as a result of the combination of a
Target Date Fund with Seligman TargETFund Core.

CLASS A -- CONTINGENT DEFERRED SALES CHARGE

For Class A shares purchased without a sales charge where a commission was
separately paid by the distributor to an authorized financial intermediary
effecting the purchase, a 1% CDSC may be charged if you sell your shares within
18 months after purchase. A CDSC will be based on the original purchase cost or
the current market value of the shares being sold, whichever is less.

CDSC -- WAIVERS OF THE CDSC FOR CLASS A SHARES. The CDSC will be waived on sales
of shares:

- to which no sales commission or transaction fee was paid to an authorized
  financial intermediary at the time of purchase.

- purchased through reinvestment of dividends and capital gain distributions.

- in the event of the shareholder's death.

- from a monthly, quarterly or annual systematic redemption plan of up to an
  annual amount of 12% of the account value on a per fund basis.

- in an account that has been closed because it falls below the minimum account
  balance.

- that result from required minimum distributions taken from retirement accounts
  upon the shareholders attainment of
  age 70 1/2.

- that result from returns of excess contributions or excess deferral amounts
  made to a retirement plan participant.

- of RiverSource funds purchased prior to Dec. 1, 2008.

- initially purchased by an employee benefit plan that is not connected with a
  plan level termination.

The distributor may, in its sole discretion, authorize the waiver of the CDSC
for additional classes of investors. Policies relating to waiving the CDSC may
be modified or withdrawn at any time.

CLASS B AND CLASS C -- CDSC ALTERNATIVE

The money market funds (except RiverSource Tax-Exempt Money Market Fund) offer
Class B and Class C shares, but only to facilitate exchanges with other funds
offering Class B and Class C shares, respectively. For example, if you own Class
B or Class C shares of another fund, but want to hold your money in a money
market fund, you may exchange into Class B or Class C shares of a money market
fund. Funds that offer Class B and Class C shares have limitations on the amount
you may

                                      C.13



invest in those share classes. If you are considering purchasing Class B or
Class C shares of a fund, please see the prospectus for that fund for any
effective purchase limitations.

Although you may not purchase Class B and Class C shares of the money market
funds directly, if you exchange into Class B or Class C shares of a money market
fund from another fund, you will be subject to the rules governing CDSC set
forth in this section.

To minimize the amount of CDSC you may pay when you sell your shares, the fund
assumes that shares acquired through reinvested dividends and capital gain
distributions (which are not subject to CDSC) are sold first. Shares that have
been in your account long enough so that they are not subject to a CDSC are sold
next. After these shares are exhausted, shares will be sold in the order they
were purchased (earliest to latest).

FOR CLASS B, the CDSC is based on the sale amount and the number of years
between purchase and sale. The following table shows how CDSC percentages on
sales decline over time:

<Table>
<Caption>
IF THE SALE IS MADE DURING THE:                                       THE CDSC PERCENTAGE RATE IS:*
                                                                   
First year                                                                          5%
Second year                                                                         4%
Third year                                                                          3%**
Fourth year                                                                         3%
Fifth year                                                                          2%
Sixth year                                                                          1%
Seventh or eighth year                                                              0%
</Table>


*   Because of rounding in the calculation, the portion of the CDSC retained by
    the distributor may vary and the actual CDSC you pay may be more or less
    than the CDSC calculated using these percentages.
**  For shares purchased in a RiverSource fund on or prior to June 12, 2009, the
    CDSC percentage for the third year is 4%.

Although there is no front-end sales charge when you buy Class B shares, the
distributor pays a sales commission of 4% to financial intermediaries that sell
Class B shares. A portion of this commission may, in turn, be paid to your
financial advisor. The distributor receives any CDSC imposed when you sell your
Class B shares.

You may not make additional purchases of Class B shares if your ROA exceeds
$49,999.99.

Class B shares purchased in a RiverSource fund prior to May 21, 2005 age on a
calendar year basis. Class B shares purchases made in a RiverSource fund
beginning May 21, 2005 age on a daily basis. For example, a purchase made on
Nov. 12, 2004 completed its first year on Dec. 31, 2004 under calendar year
aging. However, a purchase made on Nov. 12, 2005 completed its first year on
Nov. 11, 2006 under daily aging.

Class B shares originally purchased in a RiverSource fund prior to May 21, 2005
will convert to Class A shares in the ninth calendar year of ownership. Class B
shares originally purchased in a Seligman fund on or prior to June 12, 2009 will
convert to Class A shares in the month prior to the ninth year of ownership.
Class B shares purchased in a RiverSource fund beginning May 21, 2005 and Class
B shares purchased in a Seligman fund beginning June 13, 2009 will convert to
Class A shares one month after the completion of the eighth year of ownership.

FOR CLASS C, a 1% CDSC may be charged if you sell your shares within one year
after purchase. Although there is no front-end sales charge when you buy Class C
shares, the distributor pays a total amount up to 1% (including sales commission
and advance of service fees) to financial intermediaries that sell Class C
shares. See "Buying and Selling Shares -- Distribution and Service Fees." A
portion of this commission may, in turn, be paid to your financial advisor. The
distributor receives any CDSC imposed when you sell your Class C shares. You may
not make additional purchases of Class C shares if your ROA exceeds $999,999.99.

For both Class B and Class C shares, the amount of any CDSC you pay will be
based on the lower of the original purchase price of those shares or current net
asset value. Because the CDSC is imposed only on sales that reduce your total
purchase payments, you do not have to pay a CDSC on any amount that represents
appreciation in the value of your shares, income earned by your shares, or
capital gains. In addition, the CDSC on your sale, if any, will be based on your
oldest purchase payment. The CDSC on the next amount sold will be based on the
next oldest purchase payment.

EXAMPLE

Assume you had invested $10,000 in Class B shares and that your investment had
appreciated in value to $12,000 after 3 1/2 years, including reinvested
dividends and capital gain distributions. You could sell up to $2,000 worth of
shares without paying a CDSC ($12,000 current value less $10,000 purchase
amount). If you sold $2,500 worth of shares, the CDSC would apply to the $500
representing part of your original purchase price. The CDSC rate would be 3%
because the sale was made during the fourth year after the purchase.


                                      C.14



CDSC -- WAIVERS OF THE CDSC FOR CLASS B SHARES. The CDSC will be waived on sales
of shares:

- in the event of the shareholder's death.

- that result from required minimum distributions taken from retirement accounts
  upon the shareholders' attainment of age 70 1/2.

- sold under an approved substantially equal periodic payment arrangement.

  more detail in the SAI.

For more information regarding waivers of the CDSC for Class B shares, please

The distributor may, in its sole discretion, authorize the waiver of the CDSC
for additional classes of investors. Policies relating to waiving the CDSC may
be modified or withdrawn at any time.

CDSC -- WAIVERS OF THE CDSC FOR CLASS C SHARES. The CDSC will be waived on sales
of shares:

  financial intermediary at the time of purchase.

- that result from required minimum distributions taken from retirement accounts
  upon the shareholders' attainment of age 70 1/2.

CLASS I, CLASS R2, CLASS R3, CLASS R4, CLASS R5, CLASS W AND CLASS Y -- NO SALES
CHARGE. For each of Class I, Class R2, Class R3, Class R4, Class R5 and Class W
there is no initial sales charge or CDSC.

OPENING AN ACCOUNT

Financial institutions are required by law to obtain certain personal
information from each person who opens an account in order to verify the
identity of the person. As a result, when you open an account you will be asked
to provide your name, permanent street address, date of birth, and Social
Security or Employer Identification number. You may also be asked for other
identifying documents or information. If you do not provide this information,
the fund or the financial intermediary through which you are investing in the
fund may not be able to open an account for you. If the fund or the financial
intermediary through which you are investing in the fund is unable to verify
your identity, your account may be closed, or other steps may be taken, as
deemed appropriate.

When you buy shares, your order will be priced at the next NAV calculated after
your order is accepted by the fund or an authorized financial intermediary. Any
applicable sales charge will be added to the purchase price for Class A shares.

You may establish and maintain your account with an authorized financial
intermediary or directly with the fund. The fund may appoint servicing agents to
accept purchase orders and to accept exchange (and sale) orders on its behalf.
Accounts established with the fund will be supported by the fund's transfer
agent.

 METHODS OF PURCHASING SHARES

These methods of purchasing shares generally apply to Class A, Class B, and
Class C shares.

Please contact your financial intermediary for information regarding wire or
electronic funds transfer.

IMPORTANT: Payments sent by electronic fund transfers (ACH), a bank
authorization or check that are not guaranteed may take up to 14 days to clear.
If you request a sale within 14 days of purchase, this may cause your sale
request to fail to process if the requested amount includes unguaranteed funds.

EXCHANGING OR SELLING SHARES

You may exchange or sell shares by having your financial intermediary process
your transaction. If you maintain your account directly with your financial
intermediary, you must contact that financial intermediary to exchange or sell
shares of the fund. If your account was established with the fund, there are a
variety of methods you may use to exchange or sell shares of the fund.

 WAYS TO REQUEST AN EXCHANGE OR SALE OF SHARES

ACCOUNT ESTABLISHED WITH YOUR FINANCIAL INTERMEDIARY

ALL REQUESTS       You can exchange or sell shares by having your financial
                   intermediary process your transaction. The financial
                   intermediary through which you purchased shares may have
                   different policies not described in this prospectus,
                   including different transaction limits, exchange policies and
                   sale procedures.

CHECK REDEMPTION SERVICE

Class A shares of the money market funds offer check writing privileges. If you
have $2000 in a money market fund, you may request checks which may be drawn
against your account. You can elect this service on your initial application,
or, thereafter. Call (800) 221-2450 for the appropriate forms to establish this
service. If you own Class A shares that were both in another fund at NAV because
of the size of the purchase, and then exchanged into a money market fund, check
redemptions may be subject to a CDSC.

EXCHANGES

Generally, you may exchange your fund shares for shares of the same class of any
other publicly offered fund in the RiverSource Family of Funds without a sales
charge. For complete information on the fund you are exchanging into, including
fees and expenses, read that fund's prospectus carefully. Your exchange will be
priced at the next NAV calculated after your transaction request is received in
good order. You may be subject to a sales charge if you exchange from a money
market fund into an equity or fixed income fund.

IF YOU HOLD YOUR FUND SHARES IN AN ACCOUNT WITH AMERIPRISE FINANCIAL SERVICES,
YOU MAY HAVE LIMITED EXCHANGEABILITY WITHIN THE RIVERSOURCE FAMILY OF FUNDS.

MARKET TIMING

SHORT-TERM TRADING AND OTHER SO-CALLED MARKET TIMING PRACTICES ARE FREQUENT
TRADING PRACTICES BY CERTAIN SHAREHOLDERS INTENDED TO PROFIT AT THE EXPENSE OF
OTHER SHAREHOLDERS BY SELLING SHARES OF A FUND SHORTLY AFTER PURCHASE. MARKET
TIMING MAY ADVERSELY IMPACT A FUND'S PERFORMANCE BY PREVENTING THE INVESTMENT
MANAGER FROM FULLY INVESTING THE ASSETS OF THE FUND, DILUTING THE VALUE OF
SHARES HELD BY LONG-TERM SHAREHOLDERS, OR INCREASING THE FUND'S TRANSACTION
COSTS.

FOR A FUND ORGANIZED AS A FUND-OF-FUNDS, ITS ASSETS CONSIST PRIMARILY OF SHARES
OF THE UNDERLYING FUNDS IN WHICH IT INVESTS. THE UNDERLYING FUNDS MAY BE MORE
SUSCEPTIBLE TO THE RISKS OF MARKET TIMING. FUNDS THAT INVEST DIRECTLY IN
SECURITIES THAT TRADE INFREQUENTLY MAY BE VULNERABLE TO MARKET TIMERS WHO SEEK
TO TAKE ADVANTAGE OF INEFFICIENCIES IN THE SECURITIES MARKETS. FUNDS AND THE
UNDERLYING FUNDS THAT INVEST IN SECURITIES THAT TRADE ON OVERSEAS SECURITIES
MARKETS MAY BE VULNERABLE TO MARKET TIMERS WHO SEEK TO TAKE ADVANTAGE OF CHANGES
IN THE VALUES OF SECURITIES BETWEEN THE CLOSE OF OVERSEAS MARKETS AND THE CLOSE
OF U.S. MARKETS, WHICH IS GENERALLY THE TIME AT WHICH A FUND'S NAV IS
CALCULATED. TO THE EXTENT THAT A FUND OR UNDERLYING FUND HAS SIGNIFICANT
HOLDINGS OF SMALL CAP STOCKS, FLOATING RATE LOANS, HIGH YIELD BONDS, TAX-EXEMPT
SECURITIES OR FOREIGN SECURITIES, THE RISKS OF MARKET TIMING MAY BE GREATER FOR
THE FUND THAN FOR OTHER FUNDS. SEE "PRINCIPAL INVESTMENT STRATEGIES" FOR A
DISCUSSION OF THE TYPES OF SECURITIES IN WHICH YOUR FUND INVESTS. SEE "PRICING
AND VALUING OF FUND SHARES" FOR A DISCUSSION OF THE FUNDS' POLICY ON FAIR VALUE
PRICING, WHICH IS INTENDED, IN PART, TO REDUCE THE FREQUENCY AND EFFECT OF
MARKET TIMING.


                                      C.19



THE FUNDS' BOARD HAS ADOPTED A POLICY THAT IS DESIGNED TO DETECT AND DETER
MARKET TIMING THAT MAY BE HARMFUL TO THE FUNDS. EACH FUND SEEKS TO ENFORCE THIS
POLICY THROUGH ITS SERVICE PROVIDERS AS FOLLOWS:

- The fund tries to distinguish market timing from trading that it believes is
  not harmful, such as periodic rebalancing for purposes of asset allocation or
  dollar cost averaging or other purchase and exchange transactions not believed
  to be inconsistent with the best interest of fund shareholders or the Board's
  policy. The fund uses a variety of techniques to monitor for and detect
  abusive trading practices. These techniques may vary depending on the type of
  fund, the class of shares and where the shares are maintained. Under the
  fund's procedures, there is no set number of transactions in the fund that
  constitutes market timing. Even one purchase and subsequent sale by related
  accounts may be market timing. Generally, the fund seeks to restrict the
  exchange privilege of an investor who makes more than three exchanges into or
  out of the fund in any 90-day period. Accounts held by a retirement plan or a
  financial intermediary for the benefit of its participants or clients, which
  typically engage in daily transactions, are not subject to this limit,
  although the fund may seek the assistance of financial intermediaries in
  applying similar restrictions on their participants or clients. The fund's
  ability to monitor and discourage abusive trading practices in omnibus
  accounts is more limited.

- The fund may rely on the monitoring policy of a financial intermediary, for
  example, a retirement plan administrator or similar financial intermediary
  authorized to distribute the funds, if it determines the policy and procedures
  of such financial intermediaries are sufficient to protect the fund and its
  shareholders.

- If an investor's trading activity is determined to be market timing or
  otherwise harmful to existing shareholders, the fund reserves the right to
  modify or discontinue the investor's exchange privilege or reject the
  investor's purchases or exchanges, including purchases or exchanges accepted
  by a financial intermediary. The fund may treat accounts it believes to be
  under common control as a single account for these purposes, although it may
  not be able to identify all such accounts.

- Although the fund does not knowingly permit market timing, it cannot guarantee
  that it will be able to identify and restrict all short-term trading activity.
  The fund receives purchase and sale orders through financial intermediaries
  where market timing activity may not always be successfully detected.

Other exchange policies:

- Exchanges must be made into the same class of shares of the share class being
  exchanged out of.

- Exchanges into RiverSource Tax-Exempt Money Market Fund may be made only from
  Class A shares.

- If your exchange creates a new account, it must satisfy the minimum investment
  amount for new purchases.

- Once the fund receives your exchange request, you cannot cancel it after the
  market closes.

- Shares of the purchased fund may not be used on the same day for another
  exchange or sale.

- New investments in Class A shares of a money market fund may be exchanged for
  either Class A, Class B or Class C shares of any other publicly offered fund
  in the RiverSource Family of Funds.

- If you exchange shares from Class A shares of a money market fund to another
  fund in the RiverSource Family of Funds, any further exchanges must be between
  shares of the same class. For example, if you exchange from Class A shares of
  a money market fund into Class B shares of another fund in the RiverSource
  Family of Funds, you may not exchange from Class B shares of that fund back to
  Class A shares of a money market fund. Exchange rules for money market funds
  are illustrated in the following tables.

- Shares of Class W originally purchased, but no longer held in a discretionary
  managed account, may not be exchanged for Class W shares of another fund. You
  may continue to hold these shares in the fund. Changing your investment to a
  different fund will be treated as a sale and purchase, and you will be subject
  to applicable taxes on the sale and sales charges on the purchase of the new
  fund.

- If your shares are subject to a CDSC, you will not be charged a CDSC upon the
  exchange of those shares. Any CDSC will be deducted when you sell the shares
  you received from the exchange. The CDSC imposed at that time will be based on
  the period that begins when you bought shares of the original fund and ends
  when you sell the shares of the fund you exchanged to.

</Table>


If your initial investment was in a money market fund and you exchange into an
equity or fixed income fund, you will pay an initial sales charge if you
exchange into Class A and be subject to a CDSC if you exchange into Class B or
Class C.

If your initial investment was in Class A shares of an equity or fixed income
fund and you exchange shares into a money market fund, you may exchange that
amount to another fund, including dividends earned on that amount, without
paying a sales charge.

SELLING SHARES

You may sell your shares at any time. The payment will be sent within seven days
after your request is received in good order.

When you sell shares, the amount you receive may be more or less than the amount
you invested. Your sale price will be the next NAV calculated after your request
is received in good order, minus any applicable CDSC.

REPURCHASES. You can change your mind after requesting a sale of shares and use
all or part of the sale proceeds to purchase new shares of a fund in the
RiverSource Family of Funds. If your original purchase was in Class A or Class
B, you may use all or part of the sale proceeds to purchase new Class A shares
in any fund account linked together for ROA purposes. Your repurchase will be in
Class A shares at NAV, up to the amount of the sale proceeds. For a Class A
repurchase on shares that were originally charged a CDSC, the amount of the CDSC
will be reinvested at the NAV on the date the repurchase is processed.
Repurchases of Class B shares will also be in Class A shares at NAV. Any CDSC
paid upon redemption of your Class B shares will not be reimbursed. If your
original purchase was in Class C, you will be allowed to reinvest in the same
Class C account and fund you originally purchased. In a Class C repurchase, the
CDSC you paid will be reinvested and the shares will be deemed to have the
original cost and purchase date for purposes of applying the CDSC (if any) to
subsequent redemptions. Systematic withdrawals and purchases will be excluded
from this policy.

In order for you to take advantage of this repurchase waiver, you must notify
your financial intermediary or the fund's transfer agent if your account is held
at the fund within 90 days of the date your sale request was processed. Contact
your financial intermediary for information on required documentation. The
repurchase privilege may be modified or discontinued at any time and use of this
option may have tax consequences.

If you sold shares of a Seligman fund on or before February 3, 2009 and wish to
repurchase shares, you have the option of taking advantage of the current
repurchase policy (described above) within 90 days of the date your sale request
was processed, or you may use all or part of your sale proceeds to purchase
shares of the fund you sold or any other fund in the RiverSource Family of Funds
without paying an initial sales charge or, if you paid a CDSC when you sold your
shares, receiving a credit for the applicable CDSC, within 120 days of the date
your sale request was processed. Contact your financial intermediary or, if you
opened an account directly with the fund, the transfer agent, for more
information on the required documentation to complete a repurchase transaction.

The fund reserves the right to redeem in kind.

For more details and a description of other sales policies, please see the SAI.


                                      C.21



PRICING AND VALUING OF FUND SHARES

For classes of shares sold with an initial sales charge, the public offering or
purchase price is the net asset value plus the sales charge. For funds or
classes of shares sold without an initial sales charge, the public offering
price is the NAV.

Orders in good form are priced at the NAV next determined after you place your
order. Good form or good order means that your instructions have been received
in the form required by the fund. This may include, for example, providing the
fund name and account number, the amount of the transaction and all required
signatures.

The NAV is the value of a single share of the fund. The NAV is determined by
dividing the value of the fund's assets, minus any liabilities, by the number of
shares outstanding. The NAV is calculated as of the close of business on the New
York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time, on each day that
the NYSE is open. For a fund organized as a fund-of-funds, the assets will
consist primarily of shares of the underlying funds, which are valued at their
NAVs. Securities are valued primarily on the basis of market quotations and
floating rate loans are valued primarily on the basis of indicative bids. Both
market quotations and indicative bids are obtained from outside pricing services
approved and monitored under procedures adopted by the Board. Certain short-term
securities with maturities of 60 days or less are valued at amortized cost.

When reliable market quotations or indicative bids are not readily available,
investments are priced at fair value based on procedures adopted by the Board.
These procedures are also used when the value of an investment held by a fund or
underlying fund is materially affected by events that occur after the close of a
securities market but prior to the time as of which the fund's or underlying
fund's NAV is determined. Valuing investments at fair value involves reliance on
judgment. The fair value of an investment is likely to differ from any available
quoted or published price. To the extent that a fund or an underlying fund has
significant holdings of small cap stocks, high yield bonds, floating rate loans,
tax-exempt securities or foreign securities that may trade infrequently, fair
valuation may be used more frequently than for other funds. The funds use an
unaffiliated service provider to assist in determining fair values for foreign
securities.

Foreign investments are valued in U.S. dollars. Some of a fund's or an
underlying fund's securities may be listed on foreign exchanges that trade on
weekends or other days when the fund does not price its shares. In that event,
the NAV of the fund's or underlying fund's shares may change on days when
shareholders will not be able to purchase or sell the fund's or underlying
fund's shares.

For money markets funds -- The fund's investments are valued at amortized cost,
which approximates market value, as explained in the SAI. Although the fund
cannot guarantee it will always be able to maintain a constant net asset value
of $1 per share, it will use its best efforts to do so.

DISTRIBUTIONS AND TAXES

As a shareholder you are entitled to your share of your fund's net income and
net gains. Each fund distributes dividends and capital gains to qualify as a
regulated investment company and to avoid paying corporate income and excise
taxes.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Your fund's net investment income is distributed to you as dividends. Dividends
may be composed of qualified dividend income, which is eligible for preferential
tax rates under current tax law, as well as other ordinary dividend income,
which may include dividends which are non-qualified dividends, interest income
and short-term capital gains. Because of the types of income earned by fixed
income funds, it is unlikely the funds will distribute qualified dividend
income. Generally, capital gains are realized when a security is sold for a
higher price than was paid for it. Generally, capital losses are realized when a
security is sold for a lower price than was paid for it. Typically, each
realized capital gain or loss is long-term or short-term depending on the length
of time the fund held the security. Realized capital gains and losses offset
each other. The fund offsets any net realized capital gains by any available
capital loss carryovers. Net short-term capital gains, if any, are included in
net investment income and are taxable as ordinary income when distributed to the
shareholder. Net realized long-term capital gains, if any, are distributed by
the end of the calendar year as capital gain distributions. If the fund's
distributions exceed its current and accumulated earnings and profits, that
portion of the fund's distributions will be treated as a return of capital to
the shareholders to the extent of their basis in their shares. A return of
capital will generally not be taxable; however, any amounts received in excess
of basis are treated as capital gain. Forms 1099 sent to shareholders report any
return of capital.

Certain derivative instruments subject the fund to special tax rules, the effect
of which may be to accelerate income to the fund, defer fund losses, cause
adjustments in the holding periods of fund securities, convert capital gains
into ordinary income and convert short-term capital losses into long-term
capital losses. These rules could therefore affect the amount, timing and
character of distributions to shareholders.

For Seligman TargETFund 2045, Seligman TargETFund 2035, Seligman TargETFund
2025, Seligman TargETF 2015 and Seligman TargETFund Core (the Seligman
TargETFunds) -- The Funds may purchase or sell (write) options. In general,

                                      C.22



option premiums which may be received by the Funds are not immediately included
in the income of the Funds. Instead, such premiums are taken into account when
the option contract expires, the option is exercised by the holder, or the Funds
transfer or otherwise terminate the option. If an option written by a Fund is
exercised and such Fund sells or delivers the underlying security, such Fund
generally will recognize capital gain or loss equal to (a) the sum of the
exercise price and the option premium received by the Fund minus (b) the Fund's
basis in the security. Such gain or loss generally will be short-term or long-
term depending upon the holding period of the underlying security. Gain or loss
with respect to any termination of a Fund's obligation under an option other
than through the exercise of the option and the related sale or delivery of the
underlying security generally will be short-term gain or loss. Thus, for
example, if an option written by a Fund expires unexercised, such Fund generally
will recognize short-term gain equal to the premium received.

The Seligman TargETFunds generally will pay any dividends from its net
investment income and distributes any net capital gains realized on investments
at least annually (Seligman TargETFund Core generally will pay dividends from
its net investment income on a quarterly basis). Because each Seligman
TargETFund may sell underlying ETFs, US government securities and short-term
debt instruments: (a) to accommodate redemptions of its shares; (b) in respect
of the Target Date Funds, to implement the process of migration; and (c) to
adjust the percentages of its assets invested in each underlying ETF, US
government securities, short-term debt instruments, cash and cash equivalents in
response to economic, market or other conditions or events, and changes in
Seligman Time Horizon Matrix (the asset allocation methodology utilized by the
Seligman TargETFunds), each Seligman TargETFund may generate net capital gains
(including short-term capital gains that are generally taxed to shareholders at
ordinary income tax rates) for investors that may be higher than the net capital
gains ordinarily incurred by an investor through an investment in another asset
allocation fund that has broader investment ranges or an asset allocation
strategy designed by the investor. In addition, due to federal income tax laws,
each Seligman TargETFund may not fully utilize capital losses (to offset capital
gains) from the sale of underlying ETFs at a loss. In addition, underlying ETFs
may distribute capital gains to the Seligman TargETFunds.

REINVESTMENTS

Dividends and capital gain distributions are automatically reinvested in
additional shares in the same class of the fund unless you request distributions
in cash. The financial intermediary through which you purchased shares may have
different policies.

Distributions are reinvested at the next calculated NAV after the distribution
is paid. If you choose cash distributions, you will receive cash only for
distributions declared after your request has been processed.

TAXES

If you buy shares shortly before the record date of a distribution, you may pay
taxes on money earned by the fund before you were a shareholder. You will pay
the full pre-distribution price for the shares, then receive a portion of your
investment back as a distribution, which may be taxable.

For tax purposes, an exchange is considered a sale and purchase, and may result
in a gain or loss. A sale is a taxable transaction. Generally, if you sell
shares for less than their cost, the difference is a capital loss or if you sell
shares for more than their cost, the difference is a capital gain. Your gain may
be short term (for shares held for one year or less) or long term (for shares
held for more than one year).

You may not create a tax loss or reduce a tax gain, based on paying a sales
charge, by exchanging shares before the 91st day after the day of purchase. If
you buy Class A shares and exchange into another fund before the 91st day after
the day of purchase, you may not be able to include the sales charge in your
calculation of tax gain or loss on the sale of the first fund you purchased. The
sales charge may be included in the calculation of your tax gain or loss on a
subsequent sale of the second fund you purchased. For more information, see the
SAI.

REITs often do not provide complete tax information until after the calendar
year-end; generally mid to late January and continuing through early February.
Consequently, if your fund has significant investments in REITs, you may not
receive your Form 1099-DIV until February. Other RiverSource funds tax
statements are generally mailed in January.

FOR SELIGMAN TARGETFUNDS. Each of the Target Date Funds will automatically be
combined with Seligman TargETFund Core during their respective target years. The
investment manager expects each of these combinations to be effected as an
acquisition of the assets and liabilities of the applicable Target Date Fund in
exchange for shares of Seligman TargETFund Core at net asset value, with the
shares of Seligman TargETFund Core then distributed to shareholders of the
applicable Target Date Fund. Based on current tax rules, the investment manager
expects the combination to be effected in a non-taxable transaction. Changes in
such tax rules or other applicable law could negatively impact the combination
of a Target Date Fund with Seligman TargETFund Core.

FOR TAXABLE FUNDS. Distributions related to shares not held in IRAs or other
retirement accounts are subject to federal income tax and may be subject to
state and local taxes in the year they are declared. You must report
distributions on your tax returns, even if they are reinvested in additional
shares.


                                      C.23



Shares held in an IRA or qualified retirement account are generally subject to
different tax rules. Taking a distribution from your IRA or qualified retirement
plan may subject you to federal taxes, withholding, penalties and reporting
requirements. Please consult your tax advisor.

Income received by a fund may be subject to foreign tax and withholding. Tax
conventions between certain countries and the U.S. may reduce or eliminate these
taxes.

FOR TAX-EXEMPT FUNDS. Dividends distributed from interest earned on tax-exempt
securities (exempt-interest dividends) are exempt from federal income taxes but
may be subject to state and local taxes and potentially the alternative minimum
tax. Dividends distributed from net capital gains, if any, and other income
earned are not exempt from federal income taxes. Any taxable distributions are
taxable in the year the fund declares them regardless of whether you take them
in cash or reinvest them.

Interest on certain private activity bonds is a preference item for purposes of
the individual and corporate alternative minimum tax. To the extent the fund
earns such income, it will flow through to its shareholders and may affect those
shareholders who are subject to the alternative minimum tax. See the SAI for
more information.

Because interest on municipal bonds and notes is tax-exempt for federal income
tax purposes, any interest on money you borrow that is used directly or
indirectly to purchase fund shares is not deductible on your federal income tax
return. You should consult a tax advisor regarding its deductibility for state
and local income tax purposes.

FOR A FUND ORGANIZED AS A FUND-OF-FUNDS. Because most of the fund's investments
are shares of underlying funds, the tax treatment of the fund's gains, losses,
and distributions may differ from the tax treatment that would apply if either
the fund invested directly in the types of securities held by the underlying
funds or the fund shareholders invested directly in the underlying funds. As a
result, fund shareholders may recognize higher amounts of capital gain
distributions or ordinary income dividends than they otherwise would.

IMPORTANT: This information is a brief and selective summary of some of the tax
rules that apply to an investment in a fund. Because tax matters are highly
individual and complex, you should consult a qualified tax advisor.

GENERAL INFORMATION

AVAILABILITY AND TRANSFERABILITY OF FUND SHARES

Please consult with your financial intermediary to determine the availability of
the funds. The funds may only be purchased or sold directly or through financial
intermediaries authorized by the distributor to offer the funds. NOT ALL
FINANCIAL INSTITUTIONS ARE AUTHORIZED TO SELL THE RIVERSOURCE FAMILY OF FUNDS
AND CERTAIN FINANCIAL INTERMEDIARIES THAT OFFER THE RIVERSOURCE FAMILY OF FUNDS
MAY NOT OFFER ALL FUNDS ON ALL INVESTMENT PLATFORMS. If you set up an account at
a financial intermediary that does not have, and is unable to obtain, a selling
agreement with the distributor, you will not be able to transfer fund holdings
to that account. In that event, you must either maintain your fund holdings with
your current financial intermediary, find another financial intermediary with a
selling agreement, or sell your shares, paying any applicable CDSC. Please be
aware that transactions in taxable accounts are taxable events and may result in
income tax liability.

ADDITIONAL SERVICES AND COMPENSATION

In addition to acting as the fund's investment manager, RiverSource Investments
and its affiliates also receive compensation for providing other services to the
funds.

Administration Services. Ameriprise Financial, 200 Ameriprise Financial Center,
Minneapolis, Minnesota 55474, provides or compensates others to provide
administrative services to the funds. These services include administrative,
accounting, treasury, and other services. Fees paid by a fund for these services
are included under "Other expenses" in the expense table under "Fees and
Expenses."

Distribution and Shareholder Services. RiverSource Fund Distributors, Inc.,
50611 Ameriprise Financial Center, Minneapolis, Minnesota 55474, (the
distributor), provides underwriting and distribution services to the funds.
Under the Distribution Agreement and related distribution and shareholder
servicing plans, the distributor receives distribution and shareholder servicing
fees. The distributor may retain a portion of these fees to support its
distribution and shareholder servicing activity. The distributor reallows the
remainder of these fees (or the full fee) to the financial intermediaries that
sell fund shares and provide services to shareholders. Fees paid by a fund for
these services are set forth under "Distribution and/or service (12b-1) fees" in
the expense table under "Fees and Expenses." More information on how these fees
are used is set forth under "Investment Options -- Classes of Shares" and in the
SAI. The distributor also administers any sales charges paid by an investor at
the time of purchase or at the time of sale. See "Shareholder Fees (fees paid
directly from your investment)" under "Fees and Expenses" for the scheduled
sales charge of each share class. See "Buying and Selling Shares, Sales Charges"
for

                                      C.24



variations in the scheduled sales charges, and for how these sales charges are
used by the distributor. See "Other Investment Strategies and Risks" for the
funds' policy regarding directed brokerage.

Transfer Agency Services. RiverSource Service Corporation, 734 Ameriprise
Financial Center, Minneapolis, Minnesota 55474 (the transfer agent or
RiverSource Service Corporation), provides or compensates others to provide
transfer agency services to the funds. The funds pay the transfer agent a fee
that varies by class, as set forth in the SAI, and reimburses the transfer agent
for its out-of-pocket expenses incurred while providing these transfer agency
services to the funds. Fees paid by a fund for these services are included under
"Other expenses" in the expense table under "Fees and Expenses." RiverSource
Service Corporation pays a portion of these fees to financial intermediaries
that provide sub-recordkeeping and other services to fund shareholders. The SAI
provides additional information about the services provided and the fee
schedules for the transfer agent agreements.

Plan Administration Services. Under a Plan Administration Services Agreement,
the fund pays for plan administration services, including services such as
implementation and conversion services, account set-up and maintenance,
reconciliation and account recordkeeping, education services and administration
to various plan types, including 529 plans, retirement plans and Health Savings
Accounts. Fees paid by a fund for these services are included under "Other
expenses" in the expense table under "Fees and Expenses."

PAYMENTS TO FINANCIAL INTERMEDIARIES

The distributor and its affiliates make or support additional cash payments out
of their own resources (including profits earned from providing services to the
fund) to financial intermediaries, in connection with agreements between the
distributor and financial intermediaries pursuant to which these financial
intermediaries sell fund shares and provide services to their clients who are
shareholders of the fund. These payments and intercompany allocations
(collectively, "payments") do not change the price paid by investors in the fund
or fund shareholders for the purchase or ownership of fund shares of the fund,
and these payments are not reflected in the fees and expenses of the fund, as
they are not paid by the fund.

In exchange for these payments, a financial intermediary may elevate the
prominence or profile of the fund within the financial intermediary's
organization, and may provide the distributor and its affiliates with preferred
access to the financial intermediary's registered representatives or preferred
access to the financial intermediary's customers. These arrangements are
sometimes referred to as marketing and/or sales support payments, program and/or
shareholder servicing payments, or revenue sharing payments. These arrangements
create potential conflicts of interest between a financial intermediary's
pecuniary interest and its duties to its customers, for example, if the
financial intermediary receives higher payments from the sale of a certain fund
than it receives from the sale of other funds, the financial intermediary or its
representatives may be incented to recommend or sell shares of the fund where it
receives or anticipates receiving the higher payment instead of other investment
options that may be more appropriate for the customer. Employees of Ameriprise
Financial and its affiliates, including employees of affiliated broker-dealers,
may be separately incented to recommend or sell shares of the fund, as employee
compensation and business unit operating goals at all levels are tied to the
company's success. Certain employees, directly or indirectly, may receive higher
compensation and other benefits as investment in the fund increases. In
addition, management, sales leaders and other employees may spend more of their
time and resources promoting Ameriprise Financial and its subsidiary companies,
including RiverSource Investments and the distributor, and the products they
offer, including the fund.

These payments are typically negotiated based on various factors including, but
not limited to, the scope and quality of the services provided by the financial
intermediary, its reputation in the industry, its ability to attract and retain
assets, its access to target markets, its customer relationships, the profile
the fund may obtain within the financial intermediary, and the access the
distributor or other representatives of the fund may have within the financial
intermediary for advertisement, training or education, including opportunities
to present at or sponsor conferences for the registered representatives of the
financial intermediary and its customers.

These payments are usually calculated based on a percentage of fund assets owned
through the financial intermediary and/or as a percentage of fund sales
attributable to the financial intermediary. Certain financial intermediaries
require flat fees instead of, or in addition to, these asset-based fees as
compensation for including or maintaining a fund on their platforms, and, in
certain situations, may require the reimbursement of ticket or operational
charges -- fees that a financial intermediary charges its registered
representatives for effecting transactions in the fund. The amount of payment
varies by financial intermediary (e.g., initial platform set-up fees, ongoing
maintenance or service fees, or asset or sales based fees). The amount of
payments also varies by the type of sale. For instance, purchases of one fund
may warrant a greater or lesser amount of payments than purchases of another
fund. Additionally, sale and maintenance of shares on a stand alone basis may
result in a greater or lesser amount of payments than the sale and maintenance
of shares made through a plan, wrap or other fee-based program. Payments to
affiliates may include payments as compensation to employees of RiverSource
Investments who are licensed by the distributor in respect of certain sales and
solicitation activity on behalf of the fund. These payments may be and often are
significant. Additional information concerning the amount and calculation of
these payments is available in the fund's SAI.


                                      C.25



Payments to affiliated broker-dealers are within the range of the payments the
distributor pays to similarly-situated third party financial intermediaries and
the payments such affiliated broker-dealers receive from third party fund
sponsors related to the sale of their sponsored funds. However, because of the
large amount of fund assets (from the RiverSource Family of Funds, in aggregate)
currently held in customer accounts of the affiliated broker-dealers, the
distributor and its affiliates, in the aggregate, pay significantly more in
absolute dollars than other third-party fund sponsors pay to the affiliated
broker-dealers for the sale and servicing of their sponsored funds. This level
of payment creates potential conflicts of interest which the affiliated broker-
dealers seek to mitigate by disclosure and implementation of internal controls,
as well as the rules and regulations of applicable regulators.

From time to time, to the extent permitted by SEC and FINRA rules and by other
applicable laws and regulations, the distributor and its affiliates may make
other reimbursements or payments to financial intermediaries or their registered
representatives, including non-cash compensation, in the form of gifts of
nominal value, occasional meals, tickets, or other entertainment, support for
due diligence trips, training and educational meetings or conference
sponsorships, support for recognition programs, and other forms of non-cash
compensation permissible under regulations to which these financial
intermediaries and their representatives are subject. To the extent these are
made as payments instead of reimbursement, they may provide profit to the
financial intermediary to the extent the cost of such services was less than the
actual expense of the service.

The financial intermediary through which you are purchasing or own shares of the
fund has been authorized directly or indirectly by the distributor to sell the
fund and/or to provide services to you as a shareholder of the fund. Investors
and current shareholders may wish to take such payment arrangements into account
when considering and evaluating any recommendations they receive relating to
fund shares. If you have questions regarding the specific details regarding the
payments your financial intermediary may receive from the distributor or its
affiliates related to your purchase or ownership of the fund, please contact
your financial intermediary. The SAI contains additional detail regarding
payments made by the distributor to financial intermediaries.

The payments described in this section are in addition to fees paid by the fund
to the distributor under 12b-1 plans, which fees may be used to compensate
financial intermediaries for the distribution of fund shares and the servicing
of fund shareholders, or paid by the fund to the transfer agent under the
transfer agent agreement or plan administration agreement, which fees may be
used to support networking or servicing fees to compensate financial
intermediaries for supporting shareholder account maintenance, sub-accounting,
plan recordkeeping or other services provided directly by the financial
intermediary to shareholders or plans and plan participants, including
retirement plans, 529 plans, Health Savings Account plans, or other plans, where
participants beneficially own shares of the fund.

Financial institutions may separately charge you additional fees. See "Buying
and Selling Shares."

ADDITIONAL MANAGEMENT INFORMATION

AFFILIATED PRODUCTS. RiverSource Investments serves as investment manager to all
funds in the RiverSource Family of Funds, including those that are structured to
provide asset-allocation services to shareholders of those funds by investing in
shares of other funds (funds of funds) in the RiverSource Family of Funds
(collectively referred to as underlying funds) and to discretionary managed
accounts (collectively referred to as affiliated products) that invest
exclusively in underlying funds. These affiliated products, individually or
collectively, may own a significant percentage of the outstanding shares of the
underlying funds, and RiverSource Investments seeks to balance potential
conflicts between the affiliated products and the underlying funds in which they
invest. The affiliated products investment in the underlying funds may also have
the effect of creating economies of scale (including lower expense ratios)
because the affiliated products may own substantial portions of the shares of
underlying funds and, comparatively, a redemption of underlying fund shares by
one or more affiliated products could cause the expense ratio of an underlying
fund to increase as its fixed costs would be spread over a smaller asset base.
Because of these large positions of the affiliated products, the underlying
funds may experience relatively large purchases or redemptions. Although
RiverSource Investments may seek to minimize the impact of these transactions,
for example, by structuring them over a reasonable period of time or through
other measures, underlying funds may experience increased expenses as they buy
and sell securities to manage these transactions. When RiverSource Investments
structures transactions over a reasonable period of time in order to manage the
potential impact of the buy and sell decisions for the affiliated products,
these affiliated products, including funds of funds, may pay more or less for
shares of the underlying funds than if the transactions were executed in one
transaction. In addition, substantial redemptions by the affiliated products
within a short period of time could require the underlying fund to liquidate
positions more rapidly than would otherwise be desirable, which may have the
effect of reducing or eliminating potential gain or causing the underlying fund
to realize a loss. Substantial redemptions may also adversely affect the ability
of the investment manager to implement the underlying fund's investment
strategy. RiverSource Investments also has an economic conflict of interest in
determining the allocation of the affiliated products' assets among the
underlying funds as it earns different fees from the underlying funds.
RiverSource Investments monitors expense levels of the funds and is committed to
offering funds that are competitively priced. RiverSource

                                      C.26



Investments reports to the Board on the steps it has taken to manage any
potential conflicts. See the SAI for information on the percent of the fund
owned by affiliated products.

CASH RESERVES. A fund may invest its daily cash balance in a money market fund
selected by RiverSource Investments, including but not limited to RiverSource
Short-Term Cash Fund (Short-Term Cash Fund), a money market fund established for
the exclusive use of funds in the RiverSource Family of Funds and other
institutional clients of RiverSource Investments. While Short-Term Cash Fund
does not pay an advisory fee to RiverSource Investments, it does incur other
expenses, and is expected to operate at a very low expense ratio. A fund will
invest in Short-Term Cash Fund or any other money market fund selected by
RiverSource Investments only to the extent it is consistent with the fund's
investment objectives and policies. Short-Term Cash Fund is not insured or
guaranteed by the FDIC or any other government agency.

FUND HOLDINGS DISCLOSURE. The Board has adopted policies and procedures that
govern the timing and circumstances of disclosure to shareholders and third
parties of information regarding the securities owned by a fund. A description
of these policies and procedures is included in the SAI.

LEGAL PROCEEDINGS. Ameriprise Financial and certain of its affiliates have
historically been involved in a number of legal, arbitration and regulatory
proceedings, including routine litigation, class actions, and governmental
actions, concerning matters arising in connection with the conduct of their
business activities. Ameriprise Financial believes that the fund is not
currently the subject of, and that neither Ameriprise Financial nor any of its
affiliates are the subject of, any pending legal, arbitration or regulatory
proceedings that are likely to have a material adverse effect on the fund or the
ability of Ameriprise Financial or its affiliates to perform under their
contracts with the fund. Information regarding certain pending and settled legal
proceedings may be found in the fund's shareholder reports and in the SAI.
Additionally, Ameriprise Financial is required to make 10-Q, 10-K and, as
necessary, 8-K filings with the Securities and Exchange Commission on legal and
regulatory matters that relate to Ameriprise Financial and its affiliates.
Copies of these filings may be obtained by accessing the SEC website at
www.sec.gov.

HERE IS A BRIEF OVERVIEW OF THE CHANGES BEING RECOMMENDED FOR YOUR FUND. WE
ENCOURAGE YOU TO READ THE FULL TEXT OF THE ENCLOSED COMBINED PROXY
STATEMENT/PROSPECTUS.

Q:   WHY AM I BEING ASKED TO VOTE?

Mutual funds are required to get shareholders' approval for certain kinds of
changes, like the reorganizations proposed in this combined proxy
statement/prospectus.

Q:   IS MY VOTE IMPORTANT?

Absolutely! While the Board of Directors (the "Board") of each Fund listed above
has reviewed these reorganizations and recommends that you approve them, you
have the right to voice your opinion. Until a Fund is sure that a quorum has
been reached, it will continue to contact shareholders asking them to vote.

Q:   WHAT AM I BEING ASKED TO VOTE ON?

Shareholders are being asked to vote on the reorganization (a "Reorganization")
of one or more funds in the RiverSource Family of Funds (each a "Selling Fund"
and together, the "Selling Funds") into a corresponding fund in the RiverSource
Family of Funds (each a "Buying Fund" and together, the "Buying Funds") as noted
in the table below:

<Table>
<Caption>
SELLING FUND                                   BUYING FUND
                                            
RiverSource Partners Aggressive Growth Fund    RiverSource Mid Cap Growth Fund
RiverSource Partners Select Value Fund         RiverSource Mid Cap Value Fund
RiverSource Partners Small Cap Equity Fund     Seligman Smaller-Cap Value Fund
RiverSource Partners Small Cap Growth Fund     Seligman Frontier Fund
Seligman Global Smaller Companies Fund         RiverSource Partners International Small Cap
                                               Fund
RiverSource Tax-Exempt Money Market Fund       RiverSource Government Money Market Fund
                                               (formerly Seligman Cash Management Fund)
</Table>


If the Reorganization of your Selling Fund is approved by shareholders and the
other closing conditions are met, your shares of the Selling Fund will, in
effect, be converted into shares of the corresponding Buying Fund with the same
aggregate net asset value as your Selling Fund shares at the time of the
Reorganization. (Selling Funds and Buying Funds may be individually or
collectively referred to as a "Fund" or the "Funds.")

We encourage you to read the full text of the combined proxy
statement/prospectus to obtain a more detailed understanding of the issues.

Q:   WHY ARE THE REORGANIZATIONS BEING PROPOSED?

The Reorganization of each Selling Fund into a corresponding Buying Fund would
generally result in a larger combined fund with the same or similar investment
objectives, principal investment strategies and investment policies, which will
allow for more focused distribution, potentially increasing sales of and
economies of scale in the combined fund. Additionally, following the
Reorganization, for nearly all classes of shares of the combined fund, net
expenses will be the same or lower than they would have been for the Selling
Fund.

Q:   IF APPROVED, WHEN WILL THE REORGANIZATIONS HAPPEN?

The Reorganizations will take place as soon as practicable following shareholder
approval, and are expected to close before the end of the second quarter of
2010.



Q:   HOW DOES THE BOARD RECOMMEND THAT I VOTE?

After careful consideration, the Board of each Selling Fund recommends that you
vote FOR the Reorganization of your Selling Fund.

Q:   HOW DO I VOTE?

You can vote in one of four ways:

-  By telephone

-  By internet

-  By mail with the enclosed proxy card

-  In person at the meeting

Please refer to the enclosed proxy card for the telephone number and internet
address.

Q:   WHOM SHOULD I CALL IF I HAVE QUESTIONS?

If you have questions about any of the proposals described in the combined proxy
statement/prospectus or about voting procedures, please call the Funds' proxy
solicitor, Computershare Fund Services, toll free at 1 (866)-859-8682.

RIVERSOURCE MID CAP VALUE FUND (BUYING FUND)

RIVERSOURCE PARTNERS SELECT VALUE FUND (SELLING FUND)

INTRODUCTION TO PROPOSED FUND REORGANIZATION

Sept. 30, 2009

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the two
funds at, and for, the 12-month period ending Sept. 30, 2009. These statements
have been derived from financial statements prepared for the RiverSource Mid Cap
Value Fund and the RiverSource Partners Select Value Fund as of Sept. 30, 2009.
RiverSource Mid Cap Value Fund invests primarily in equity securities of medium-
sized companies. RiverSource Partners Select Value Fund invests primarily in
equity securities of mid-cap companies as well as companies with larger and
smaller market capitalizations. For these purposes, RiverSource Partners Select
Value Fund considers mid-cap companies to be either those with a market
capitalization of up to $10 billion or those whose market capitalization falls
within the range of the Rusell Midcap Value Index.

Under the proposed Agreement and Plan of Reorganization, share classes of
RiverSource Partners Select Value Fund would be exchanged for share classes of
RiverSource Mid Cap Value Fund.

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the two

financial statements prepared for the Seligman Smaller-Cap Value Fund and the

companies with smaller market capitalization ($3 billion or less) at the time of

RiverSource Partners Small Cap Equity Fund invests primarily in equity

liabilities of RiverSource Partners Small Cap Equity Fund in exchange for Class
A, Class B, Class C, Class I and Class R4 shares of Seligman Smaller-Cap Value

statements reflect estimates for the combined Seligman Smaller-Cap Value Fund

INTRODUCTION TO PROPOSED FUND REORGANIZATION

April 30, 2009

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the two
funds at, and for, the 12-month period ending April 30, 2009. These statements
have been derived from financial statements prepared for the Seligman Frontier
Fund and the RiverSource Partners Small Cap Growth Fund as of April 30, 2009.
Seligman Frontier Fund invests 65% of its net assets in equity securities of
small U.S. companies. RiverSource Partners Small Cap Growth Fund invests
primarily in equity securities of companies with market capitalization, at the
time of investment, of up to $2 billion, or that fall within the range of the
Russell 2000 Growth Index.

Under the proposed Agreement and Plan of Reorganization, share classes of
RiverSource Partners Small Cap Growth Fund would be exchanged for share classes
of Seligman Frontier Fund.

RiverSource Partners Small Cap Growth Fund invests primarily in equity
securities of companies with market capitalization, at the time of investment,
of up to $2 billion, or that fall within the range of the Russell 2000 Growth

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the two
funds at, and for, the 12-month period ending April 30, 2009. These statements
have been derived from financial statements prepared for the RiverSource
Partners International Small Cap Fund and the Seligman Global Smaller Companies

NOTES TO PRO FORMA FINANCIAL STATEMENTS

(Unaudited as to April 30, 2009)

1. BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the
statement of operations reflect the accounts of the two funds at, and for, the

financial statements prepared for the RiverSource Partners International Small

Each Fund is registered under the Investment Company Act of 1940 (as amended) as
a diversified, open-end management investment company. The primary investments
of each Fund are as follows:

RiverSource Partners International Small Cap Fund invests primarily in equity

Seligman Global Smaller Companies Fund invests primarily in equity securities of
smaller U.S. and non-U.S companies and may invest in companies domiciled in any
country, although it typically invests in developed countries.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of Seligman Global Smaller Companies Fund in exchange for Class A,
Class B, Class C, Class R2 and Class R5 shares of RiverSource Partners
International Small Cap Fund under U.S. generally accepted accounting
principles. The pro forma statements reflect estimates for the combined
RiverSource Partners International Small Cap Fund based on the increased asset
level of the Reorganization and associated economies of scale, adjusted to
reflect current fees.

The pro forma combining statements should be read in conjunction with the
historical financial statements of the funds incorporated by reference in the
Statement of Additional Information.

The pro forma statement of operations give effect to the proposed transaction on
the historical operations of the accounting survivor, RiverSource Partners

RIVERSOURCE GOVERNMENT MONEY MARKET FUND (BUYING FUND)

RIVERSOURCE TAX-EXEMPT MONEY MARKET FUND (SELLING FUND)

NOTES TO PRO FORMA FINANCIAL STATEMENTS

(Unaudited as to June 30, 2009)

1. BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the
statement of operations reflect the accounts of the two funds at, and for, the
12-month period ending June 30, 2009. These statements have been derived from
financial statements prepared for the RiverSource Government Money Market Fund
and the RiverSource Tax-Exempt Money Market Fund as of June 30, 2009.

Each Fund is registered under the Investment Company Act of 1940 (as amended) as
a diversified, open-end management investment company. The primary investments
of each Fund are as follows:

RiverSource Government Money Market Fund invests primarily in high-quality,
short-term money market securities that are issued or guaranteed by the U.S.
government, its agencies or instrumentalities.

RiverSource Tax-Exempt Money Market Fund invests primarily in short-term debt
obligations whose interest is exempt from federal income taxes.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of RiverSource Tax-Exempt Money Market Fund in exchange for Class A
shares of RiverSource Government Money Market Fund under U.S. generally accepted
accounting principles. The pro forma statements reflect estimates for the
combined RiverSource Government Money Market Fund based on the increased asset
level of the Reorganization and associated economies of scale, adjusted to
reflect current fees.

The pro forma combining statements should be read in conjunction with the
historical financial statements of the funds incorporated by reference in the
Statement of Additional Information.

PART C. OTHER INFORMATION

Item 15. Indemnification

Reference is made to the provisions of Articles Twelfth and Thirteenth of
Registrant's Amended and Restated Articles of Incorporation filed as Exhibit
24(b)(1) to Registrant's Post-Effective Amendment No. 30 to the Registration
Statement filed on April 29, 1997 and Article X of Registrant's Amended and
Restated By-laws filed as Exhibit Item 23(b) of Registrant's Post-Effective
Amendment No. 42 filed on May 1, 2006.

Insofar as indemnification for liabilities arising under the Securities Act of
1933, as amended, may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised by the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
