Ladies and Gentlemen:
We have acted as counsel for SIFCO Industries, Inc. (the “Company”) in connection with the
Registration Statement on Form S-8 (the “Registration Statement”) to be filed with the Securities
and Exchange Commission under the Securities Act of 1933, as amended, with respect to 221,500
common shares of the Company, $1 par value (the “Common Shares”), issuable upon the exercise of
options granted pursuant to the Company’s 1995 Stock Option Plan and 1998 Long-term Incentive Plan
(the “Plans”).
We have reviewed the Registration Statement and the Plans and have examined such other
documents, and considered such matters of law, as we have deemed necessary or appropriate for
purposes of this opinion. We also have reviewed a certificate of an officer of the Company and
have relied upon such certificate as to the various factual matters contained in the certificate.
We have assumed the genuineness of all signatures on all documents reviewed by us, the authenticity
of all documents submitted to us as originals, and the conformity to authentic originals of all
documents submitted to us as copies. We also have assumed there will be a sufficient number of
authorized Common Shares available for issuance at the time of issuance of Common Shares upon the
exercise of options granted under the Plans.
Based upon the foregoing, we are of the opinion that, when issued in accordance with the
Plans, the Common Shares so issued will be validly issued, fully paid and nonassessable.
We consent to the filing of this opinion as an exhibit to the Registration Statement. In
giving this consent, we do not admit that we come within the category of persons whose consent is
required under Section 7 of the Securities Act of 1933 or the rules and regulations under such Act.
Respectfully submitted,
/s/ Squire, Sanders & Dempsey L.L.P.
