Ladies and Gentlemen:
I have acted as counsel to American Century Mutual Funds, Inc., a Maryland
corporation (the "Company"), in connection with the Company's Registration
Statement on Form N-14 (File No. 2-14213), which relates to the Company's
authorized shares of common stock, par value One Cent ($0.01) per share (the
"Shares"), proposed to be issued in accordance with the terms of an Agreement
and Plan of Reorganization with Kopp Funds, Inc. (the "Agreement"), relating to
the proposed reorganization of the Kopp Emerging Growth Fund into the American
Century New Opportunities II Fund.
In connection with rendering the opinions set forth below, I have examined
the Registration Statement, including a form of the Agreement, which is being
filed as an exhibit thereto; the Company's Articles of Incorporation, Articles
Supplementary and Bylaws, as reflected in the Company's corporate records;
resolutions of the Board of Directors of the Company relating to the approval of
the Agreement and the issuance of the Shares; and such other documents as I
deemed relevant. In conducting my examination, I have assumed the genuineness of
all signatures, the legal capacity of all natural persons, the authenticity,
accuracy and completeness of documents purporting to be originals and the
conformity to originals of any copies of documents. I have not independently
established any facts represented in the documents so relied on.
I am a member of the Bar of the State of Missouri. The opinions expressed
in this letter are based on the facts in existence and the laws in effect on the
date hereof and are limited to the laws (other than the conflict of law rules)
of the State of Maryland that in my experience are normally applicable to the
issuance of shares by registered investment companies organized as corporations
under the law of that state and to the Securities Act of 1933, as amended (the
"1933 Act"), the Investment Company Act of 1940, as amended (the "1940 Act"),
and the regulations of the Securities and Exchange Commission (the "SEC")
thereunder. I express no opinion with respect to any other laws.
Based upon and subject to the foregoing and the qualifications set forth
below, it is my opinion that:
1. The issuance of the Shares pursuant to the Agreement has been duly
authorized by the Company.
2. When issued upon the terms provided in the Registration Statement,
subject to compliance with the 1933 Act, the 1940 Act, and applicable state laws
regulating the offer and sale of securities, and assuming the continued valid
existence of the Company under the laws of the State of Maryland, the Shares
will be validly issued, fully paid and non-assessable.

I hereby consent to the use of this opinion as an exhibit to the
Registration Statement. I assume no obligation to advise you of any changes in
the foregoing subsequent to the effectiveness of the Registration Statement. In
giving my consent I do not thereby admit that I am in the category of persons
whose consent is required under Section 7 of the 1933 Act or the rules and
regulations of the SEC thereunder. The opinions expressed herein are matters of
professional judgment and are not a guarantee of result.
Very truly yours,
