                  Re:      Principal Capital II

Ladies and Gentlemen:

                  We have acted as special Delaware counsel for Principal
Financial Group, Inc., a Delaware corporation (the "Company"), and Principal
Capital II, a Delaware statutory trust (the "Trust"), in connection with the
matters set forth herein. At your request, this opinion is being furnished to
you.

                  For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

                  (a) The Certificate of Trust of the Trust (the "Certificate of
Trust"), as filed in the office of the Secretary of State of the State of
Delaware (the "Secretary of State") on December 16, 2003;

                  (b) The Trust Agreement of the Trust, dated as of December 16,
2003, between the Company and the trustee of the Trust named therein;

                  (c) A form of Amended and Restated Trust Agreement of the
Trust (including Exhibits A, C and E thereto) (the "Trust Agreement"), to be
entered into among the Company, as depositor, the trustees of the Trust named
therein, and the holders, from time to time, of undivided beneficial interests
in the assets of the Trust, incorporated by reference as an exhibit to the
Registration Statement (as defined below);

                  (d) The Registration Statement on Form S-3, including a
preliminary prospectus (the "Prospectus"), relating to the preferred securities
of the Trust representing preferred undivided beneficial interests in the assets
of the Trust (each, a "Preferred Security" and collectively, the "Preferred
Securities"), as filed by the Company, the Trust and others as set forth therein
with the Securities and Exchange Commission on or about December 19, 2003 (the
"Registration Statement"); and

                  (e) A Certificate of Good Standing for the Trust, dated
December 17, 2003, obtained from the Secretary of State.

                  Capitalized terms used herein and not otherwise defined are
used as defined in the Trust Agreement.

                  For purposes of this opinion, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that is
inconsistent with the opinions stated herein. We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to be
true, complete and accurate in all material respects.

                  With respect to all documents examined by us, we have assumed
(i) the authenticity of all documents submitted to us as authentic originals,
(ii) the conformity with the originals of all documents submitted to us as
copies or forms, and (iii) the genuineness of all signatures.

                  For purposes of this opinion, we have assumed (i) that the
Trust Agreement and the Certificate of Trust are in full force and effect and
have not been amended, (ii) except to the extent provided in paragraph 1 below,
that each of the parties to the documents examined by us has been duly created,
organized or formed, as the case may be, and is validly existing in good
standing under the laws of the jurisdiction governing its creation, organization
or formation, (iii) the legal capacity of natural persons who are parties to the
documents examined by us, (iv) that each of the parties to the documents
examined by us has the power and authority to execute and deliver, and to
perform its obligations under, such documents, (v) that each of the parties to
the documents examined by us has duly authorized, executed and delivered such
documents, (vi) the receipt by each Person to whom a Preferred Security is to be
issued by the Trust (collectively, the "Preferred Security Holders") of a
Preferred Securities Certificate for such Preferred Security and the payment for
the Preferred Security acquired by it, in accordance with the Trust Agreement
and as described in the Registration Statement, and (vii) that the Preferred
Securities are issued and sold to the Preferred Security Holders in accordance
with the Trust Agreement and as described in the Registration Statement. We have
not participated in the preparation of the Registration Statement and assume no
responsibility for its contents.

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no

opinion on the laws of any other jurisdiction, including federal laws and rules
and regulations relating thereto. Our opinions are rendered only with respect to
Delaware laws and rules, regulations and orders thereunder that are currently in
effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1. The Trust has been duly created and is validly existing in
good standing as a statutory trust under the Delaware Statutory Trust Act.

                  2. The Preferred Securities represent valid and, subject to
the qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

                  3. The Preferred Security Holders, as beneficial owners of the
Trust, are entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Trust Agreement.

                  We consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement and to the
incorporation by reference of this opinion and consent as exhibits to any
registration statement filed in accordance with Rule 462(b) under the Securities
Act of 1933, as amended, relating to the Preferred Securities. In addition, we
hereby consent to the use of our name under the heading "Legal Opinions" in the
Prospectus. In giving the foregoing consents, we do not thereby admit that we
come within the category of Persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder. Except as stated above, without
our prior written consent, this opinion may not be furnished or quoted to, or
relied upon by, any other Person for any purpose.



                                             Very truly yours,


                                             /s/ Richards, Layton & Finger, P.A.
