Ladies and Gentlemen:

I am familiar with the establishment of the RiverSource Variable Account 10
("Account"), which is a separate account of RiverSource Life Insurance Company
("Company") established by the Company's Board of Directors according to
applicable insurance law. I also am familiar with the above-referenced
Registration Statement filed by the Company on behalf of the Account with the
Securities and Exchange Commission.

I have made such examination of law and examined such documents and records as
in my judgment are necessary and appropriate to enable me to give the following
opinion:

1. The Company is duly incorporated, validly existing and in good standing under
applicable state law and is duly licensed or qualified to do business in each
jurisdiction where it transacts business. The Company has all corporate powers
required to carry on its business and to issue the contracts.

2. The Account is a validly created and existing separate account of the Company
and is duly authorized to issue the securities registered. 3. The contracts
issued by the Company, when offered and sold in accordance with the prospectuses
contained in the Registration Statement and in compliance with applicable law,
will be legally issued and represent binding obligations of its Company in
accordance with their terms.

I hereby consent to the filing of this opinion as an exhibit to the Registration
Statement.

Sincerely,


/s/ Elisabeth A. Dahl
