PART C. OTHER INFORMATION

Item 15. Indemnification

The Articles of Incorporation of the registrant provide that the Fund shall
indemnify any person who was or is a party or is threatened to be made a party,
by reason of the fact that she or he is or was a director, officer, employee or
agent of the Fund, or is or was serving at the request of the Fund as a
director, officer, employee or agent of another company, partnership, joint
venture, trust or other enterprise, to any threatened, pending or completed
action, suit or proceeding, wherever brought, and the Fund may purchase
liability insurance and advance legal expenses, all to the fullest extent
permitted by the laws of the State of Minnesota, as now existing or hereafter
amended. The By-laws of the registrant provide that present or former directors
or officers of the Fund made or threatened to be made a party to or involved
(including as a witness) in an actual or threatened action, suit or proceeding
shall be indemnified by the Fund to the full extent authorized by the Minnesota
Business Corporation Act, all as more fully set forth in the By-laws filed as an
exhibit to this registration statement.

Insofar as indemnification for liability arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of 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.

Any indemnification hereunder shall not be exclusive of any other rights of
indemnification to which the directors, officers, employees or agents might
otherwise be entitled. No indemnification shall be made in violation of the
Investment Company Act of 1940.

Any indemnification hereunder shall not be exclusive of any other rights of
indemnification to which the trustees, officers, employees or agents might
otherwise be entitled. No indemnification shall be made in violation of the
Investment Company Act of 1940.

Ladies and Gentlemen:

     We have acted as counsel in connection with the Agreement and Plan of
Reorganization (the "Agreement") dated as of January 10, 2009 between and among:
(i) Seligman Global Fund Series, Inc., a Maryland corporation, on behalf of one
of its series, Seligman Emerging Markets Fund ("Target Fund"); (ii) RiverSource
Global Series, Inc., a Minnesota corporation, on behalf of one of its series,
Threadneedle Emerging Markets Fund ("Acquiring Fund," together with Target Fund,
the "Funds"); and (iii) RiverSource Investments, LLC, the investment adviser to
the Funds; which Reorganization is to take place as of the date of this letter
(the "Closing Date"). The Agreement describes a proposed transaction (the
"Reorganization") to occur as of the date of this letter (the "Closing Date"),
pursuant to which Acquiring Fund will acquire substantially all of the assets of
Target Fund in exchange for shares of beneficial interest in Acquiring Fund (the
"Acquiring Fund Shares") and the assumption by Acquiring Fund of all of the
liabilities of Target Fund following which the Acquiring Fund Shares received by
Target Fund will be distributed by Target Fund to its shareholders in
liquidation and termination of Target Fund. This opinion as to certain U.S.
federal income tax consequences of the Reorganization is furnished to you
pursuant to Section 9 of the Agreement. Capitalized terms not defined herein are
used herein as defined in the Agreement.

     Target Fund is a series of Seligman Global Fund Series, which is registered
under the Investment Company Act of 1940, as amended (the "1940 Act"), as an
open-end management investment company. Shares of Target Fund are redeemable at
net asset value at each shareholder's option. Target Fund has elected to be a
regulated investment company for federal income tax purposes under Section 851
of the Internal Revenue Code of 1986, as amended (the "Code").



                                                                 August 17, 2009

Seligman Emerging Markets Fund
Threadneedle Emerging Markets Fund

     Acquiring Fund is a series of RiverSource Global Series, which is
registered under the 1940 Act as an open-end management investment company.
Shares of Acquiring Fund are redeemable at net asset value at each shareholder's
option. Acquiring Fund has elected to be a regulated investment company for
federal income tax purposes under Section 851 of the Code.

     For purposes of this opinion, we have considered the Agreement, the
Combined Proxy Statement/Prospectus dated April 4, 2009 and such other items as
we have deemed necessary to render this opinion. In addition, each of the Target
Fund, the Acquiring Fund and Seligman Data Corp. ("SDC") has provided us with a
letter dated as of the date of this letter (collectively, the "Representation
Letters") representing as to certain facts, occurrences and information upon
which each of the respective entities above has indicated that we may rely in
rendering this opinion (whether or not contained or reflected in the documents
and items referred to above).

     In reviewing the foregoing materials, we have assumed, with your
permission, the authenticity of original documents, the accuracy of copies, the
genuineness of signatures, the legal capacity of signatories, and the proper
execution of documents. We have further assumed that (i) all parties to the
Agreement and any other documents examined by us have acted, and will act, in
accordance with the terms of such Agreement and documents, and that the
Reorganization will be consummated pursuant to the terms and conditions set
forth in the Agreement without the waiver or modification of any such terms and
conditions; and (ii) all representations contained in the Agreement, as well as
those representations contained in the Representation Letters, are true and
complete.

     The facts represented to us in the Representation Letters support the
conclusion that, based on the analysis and subject to the considerations set
forth below, while the matter is not free from doubt, the Reorganization
constitutes a reorganization within the meaning of Section 368(a)(1) of the
Code. The Reorganization's consequences to Target Fund shareholders, Target
Fund, and Acquiring Fund are set forth more fully below.

I.   "SUBSTANTIALLY ALL OF THE PROPERTIES" TEST: CERTAIN INSTITUTIONAL
     SHAREHOLDER REDEMPTIONS

     To qualify as a reorganization under either Code Section 368(a)(1)(C) or
368(a)(1)(D) (a "'C' or 'D' Reorganization," respectively), a target corporation
must transfer "substantially all of its 'properties' or 'assets,'" respectively,
to the acquiring corporation. For the purpose of evaluating whether a target
fund has met this "substantially all" requirement or test, it is often necessary
to determine whether amounts distributed by the target fund to meet certain
pre-reorganization redemption requests should be viewed as separate
transactions, unrelated to the reorganization, and therefore excluded from the
analysis of whether the target fund has transferred "substantially all" of its
properties (or assets) to an acquiring fund.


                                       -2-



                                                                 August 17, 2009

Seligman Emerging Markets Fund
Threadneedle Emerging Markets Fund

     During the period between June 22, 2009 and June 26, 2009, the North
Carolina College Savings and Investment Program (the "NC 529 Plan") redeemed
370,728 shares of Target Fund stock (the "NC 529 Plan Redemption"), with a value
on the date of the redemption equal to approximately 3.8% of the Combined Value
of Target Fund. For this purpose, the Combined Value of Target Fund is equal to
the net asset value of Target Fund on the Closing Date, plus the value of all
shares redeemed in the Institutional Shareholder Redemptions (as defined below),
valued in each case at the net asset value per share of Target Fund shares on
the Closing Date. Target Fund and Acquiring Fund have represented that the NC
529 Plan has no common board members or managers with either Fund, and that the
Reorganization and the NC 529 Plan Redemption were independent of and without
reference to one another. In addition, on August 12, 2009, the Seligman Data
Corp. Employees' Thrift Plan (the "SDC Thrift Plan") redeemed 24,006 shares of
Target Fund stock (the "SDC Thrift Plan Redemption," and collectively with the
NC 529 Plan Redemption, the "Institutional Shareholder Redemptions"), with a
value on the date of the redemption equal to approximately 0.3% of the Combined
Value of Target Fund. SDC, which oversees the SDC Thrift Plan, and Target Fund
and Acquiring Fund have represented: (i) that the SDC Thrift Plan Redemption
resulted from the termination of the SDC Thrift Plan in connection with the
termination of SDC's business; and (ii) that the termination of the SDC Thrift
Plan and the Reorganization were independent of and without reference to one
another.

     Based on these facts as set forth in more detail in the Representation
Letters, and based on our understanding of the relevant legal principles, in our
view the Institutional Shareholder Redemptions were not part of the plan of
Reorganization, and accordingly the Reorganization will meet the "substantially
all" requirement of Section 368(a)(1) of the Code.

II.  OPINION

     Based on the Representation Letters and customary assumptions, and our
review of the documents and items referred to above, we are of the opinion that,
although the matter is not free from doubt and subject to the final paragraphs
hereof, for U.S. federal income tax purposes:

     (i)    The Reorganization will constitute a reorganization within the
            meaning of Section 368(a) of the Code, and Target Fund and Acquiring
            Fund will each be a "party to reorganization" within the meaning of
            Section 368(b) of the Code;

     (ii)   No gain or loss will be recognized by the Target Fund upon (a) the
            transfer of its assets to Acquiring Fund in exchange for Acquiring
            Fund Shares and the assumption by Acquiring Fund of all liabilities
            of Target Fund or (b) the distribution of the Acquiring Fund Shares
            by Target Fund to its shareholders in liquidation;


                                       -3-



                                                                 August 17, 2009

Seligman Emerging Markets Fund
Threadneedle Emerging Markets Fund

     (iii)  No gain or loss will be recognized by Acquiring Fund upon receipt of
            the assets of Target Fund in exchange for Acquiring Fund Shares and
            the assumption by Acquiring Fund of all liabilities of Target Fund;

     (iv)   The tax basis in the hands of Acquiring Fund of the assets of Target
            Fund transferred to the Acquiring Fund in the Reorganization will be
            the same as the tax basis of such assets in the hand of Target Fund
            immediately prior to the transfer;

     (v)    The holding periods of the assets of Target Fund in the hands of
            Acquiring Fund will include the periods during which such assets
            were held by Target Fund;

     (vi)   No gain or loss will be recognized by Target Fund shareholders upon
            the exchange of their shares of Target Fund for the Acquiring Fund
            Shares;

     (vii)  The aggregate tax basis of the Acquiring Fund Shares each Target
            Fund shareholder receives in the Reorganization will be the same as
            the aggregate tax basis of his or her Target Fund shares exchanged
            therefore;

     (viii) A Target Fund shareholder's holding period for the Acquisition Fund
            Shares will include the period for which he or she held Target Fund
            shares exchanged therefor, provided that the shareholder held such
            Target Fund shares as capital assets on the date of the exchange;
            and

     (ix)   Acquiring Fund will succeed to and take into account the items of
            Target 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.

We 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 transfer would otherwise be a non-taxable
transaction.

     In connection with this opinion, we call your attention to Revenue Ruling
87-76, 1987-2 C.B. 84, published by the Internal Revenue Service (the "IRS"). In
that ruling, the IRS held that the so-called "continuity of business enterprise"
requirement necessary for tax-free reorganization treatment was not met in the
case of an acquisition of an investment company which invested in corporate
stocks and bonds by an investment company which invested in municipal bonds.
Specifically, the IRS based its ruling on its conclusion that the business of
investing in corporate stocks and bonds is not the same line of business as
investing in municipal bonds. We believe that the IRS's conclusion in this
ruling has always been questionable. In addition, a series of private letter
rulings issued in July of 2005 suggests that the IRS's position


                                       -4-



                                                                 August 17, 2009

Seligman Emerging Markets Fund
Threadneedle Emerging Markets Fund

on this issue is evolving: the IRS relied upon historic business representations
to conclude that the reorganizations satisfied the continuity of business
enterprise requirement. However, even if the IRS's 1987 revenue ruling were a
correct statement of law, the facts of the Reorganization would be
distinguishable from those in the ruling.

     We believe that Acquiring Fund and Target Fund are both engaged in the same
line of business: each is an open-end investment company that seeks long-term
capital appreciation by investing primarily in equity securities of emerging
market companies. After the Reorganization, Acquiring Fund will continue that
line of business for the benefit of the stockholders of both Target and
Acquiring Funds. While Acquiring Fund will dispose of securities formerly held
by Target Fund, these dispositions will be fully consistent with the shared
historic investment policies of both Funds and all proceeds generated by such
dispositions will be reinvested in a manner fully consistent with such policies.
In these circumstances, we are of the opinion that Acquiring Fund will have
continued the historic business of Target Fund for the benefit of, among others,
the historic stockholders of Target Fund, and that the continuity of business
enterprise doctrine should, as a result, be fulfilled. However, because Revenue
Ruling 87-76 is the only ruling on which taxpayers can rely (i.e., the only
ruling that is not a private letter ruling) dealing specifically with the
application of the "continuity of business enterprise" requirement to a
reorganization involving investment companies, our opinion cannot be free from
doubt. No ruling has been or will be obtained from the IRS as to the subject
matter of this opinion and there can be no assurance that the IRS or a court of
law will concur with the opinion set forth above.

     Our opinion is based on the Code, Treasury Regulations, IRS rulings,
judicial decisions, and other applicable authority, all as in effect on the date
of this opinion. The legal authorities on which this opinion is based may be
changed at any time. Any such changes may be retroactively applied and could
modify the opinions expressed above.

                                        Very truly yours,


                                        /s/ Ropes & Gray LLP

     Acquiring Fund is a series of RiverSource Global Series, Inc., which is

Shares of Acquiring Fund are redeemable at net asset value at each shareholder's
option. Acquiring Fund has elected to be a regulated investment company for
federal income tax purposes under Section 851 of the Code.

     For purposes of this opinion, we have considered the Agreement, the
Combined Proxy Statement/Prospectus dated April 4, 2009 and such other items as
