Ladies and Gentlemen:

      We have acted as special counsel for EaglePicher Incorporated, an Ohio
corporation (the "Company") and the Guarantors (defined below) in connection
with the offer to exchange (the "Exchange Offer") up to $250,000,000 aggregate
principal amount of 9 3/4% Senior Subordinated Notes due 2013 issued and sold in
a Rule 144A offering (the "Notes") for registered 9 3/4% Senior Subordinated
Notes due 2013 (the "Exchange Notes"). The Exchange Offer is made pursuant to
the Registration Statement on Form S-4 filed by the Company and the Guarantors
with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Act"), on November 5, 2003 (the
"Registration Statement"). In connection with the Registration Statement, we
have been requested to render the opinions set forth herein.

      The Exchange Notes will be issued pursuant to the terms of the Indenture,
dated August 7, 2003 (the "Indenture"), among the Company, the Guarantors and
Wells Fargo Bank, National Association, as indenture trustee (the "Trustee").
The Company's payment obligations with respect to the Exchange Notes are being
guaranteed, jointly and severally on a subordinated basis, by the Guarantors.
EaglePicher Holdings, Inc., a Delaware corporation ("Holdings"), Carpenter
Enterprises, Limited, a Michigan corporation ("Carpenter"), Daisy Parts, Inc., a
Michigan corporation ("Daisy"), Eagle-Picher Far East, Inc., a Delaware
corporation ("Far East"), EaglePicher Filtration & Minerals, Inc., a Nevada
corporation ("Filtration & Minerals"), EaglePicher Technologies, LLC, a Delaware
limited liability company ("Technologies"), and EaglePicher Automotive, Inc., a
Michigan corporation ("Automotive") are collectively referred to herein as the
"Guarantors," the guarantees of the Guarantors with respect to the Exchange
Notes are collectively referred to herein as the "Guarantees," and the Exchange
Notes and the Guarantees are collectively referred to herein as the
"Securities."

      In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Certificate of
Incorporation and the Regulations of the Company, (ii) the comparable
organizational documents for each of the Guarantors, (iii) certain resolutions
and/or

written consents of the Boards of Directors of the Company and of each of the
Guarantors, (iv) the Indenture, (v) the Registration Statement, (vi) a specimen
of the Exchange Notes and the Guarantees; and (vii) such other corporate
records, agreements, documents and other instruments of the Company and the
Guarantors and such certificates or comparable documents of public officials and
of officers and representatives of the Company and the Guarantors as we deemed
necessary or appropriate for purposes of rendering the opinions set forth below.

      In such examination and in rendering the opinions set forth below, we have
assumed (i) the legal capacity of all natural persons, (ii) the genuineness of
all signatures, (iii) the authority of all signatories, (iv) the authenticity
and completeness of all documents submitted to us as forms of the documents to
be executed, (v) the conformity to original documents of all documents submitted
to us as certified or photostatic copies, (vi) that the parties' choice of New
York law to govern the Indenture and the Securities would be upheld if
challenged, and (vii) that the Securities will be issued as described in the
Registration Statement. As to any facts material to this opinion which we did
not independently establish or verify, we have relied upon statements or
representations of officers and/or other representatives of the Company, the
Guarantors and others, all of which statements and representations we have
assumed to be true and correct in all respects as of the date hereof.

      Based upon and subject to the assumptions, limitations, qualifications and
exceptions set forth herein, as of the effective date of the Registration
Statement, it is our opinion that:

      1. The Company is a corporation duly incorporated and in good standing
under the laws of the State of Ohio, and has duly authorized the execution,
delivery and performance of the Indenture and the Exchange Notes.

      2. Holdings and Far East are corporations duly incorporated and are in
good standing under the laws of the State of Delaware, and have duly authorized
the execution, delivery and performance of the Indenture and their respective
Guarantees.


      3. Carpenter, Daisy and Automotive are corporations duly incorporated and
are in good standing under the laws of the State of Michigan, and have duly
authorized the execution, delivery and performance of the Indenture and their
respective Guarantees.

      4. Technologies is a limited liability company duly organized and is
validly existing under the laws of the State of Delaware, and has duly
authorized the execution, delivery and performance of the Indenture and its
Guarantee.


      5. Filtration & Minerals is a corporation duly incorporated and is in good
standing under the laws of the State of Nevada, and has duly authorized the
execution, delivery and performance of the Indenture and its Guarantee.

      6. Assuming that (i) the Indenture has been duly authorized, executed and
delivered by the Trustee, (ii) the Exchange notes are duly executed and issued
by the Company, (iii) the Guarantees are duly executed and issued by the
respective Guarantors, and (iv) the Exchange Notes have been authenticated by
the Trustee in the manner set forth in the Indenture, and upon exchange and
delivery as described in the Registration Statement, the Exchange Notes will
constitute valid and legally binding obligations of the Company, enforceable
against the Company in accordance with their terms and entitled

to the benefits of the Indenture, except to the extent that the enforceability
thereof may be limited by (A) bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium, fraudulent transfer or other laws relating to
creditors' rights generally, and (B) general principles of equity (regardless of
whether such enforcement is considered in a proceeding in equity or at law), the
discretion of the court before which proceedings may be brought and an implied
covenant of good faith and fair dealing.

      7. Assuming that the Indenture has been duly authorized, executed and
delivered by the Trustee, the Indenture constitutes a valid and legally binding
instrument of the Company and each of the Guarantors, enforceable against the
Company and each of the Guarantors in accordance with its terms, and, based on
such assumption, the Guarantees will constitute valid and legally binding
obligations of each of the respective Guarantors, enforceable against each
Guarantor in accordance with their terms; provided, however, in each case that
the enforceability thereof may be limited by (A) bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium, fraudulent transfer or other
laws relating to creditors' rights generally, and (B) general principles of
equity (regardless of whether such enforcement is considered in a proceeding in
equity or at law), the discretion of the court before which proceedings may be
brought and an implied covenant of good faith and fair dealing.

      The foregoing opinions are subject to the following qualifications and
limitations:

      (a) With respect to our opinions set forth in Paragraph 1, as to matters
of Ohio law, we have relied solely on the Certificate of Good Standing issued by
the State of Ohio dated as of a recent date and certain resolutions of the

matters of Delaware law, we have relied solely on the Certificates of Good
Standing and Certificates of Existence issued by the State of Delaware dated as

East, and Technologies dated as of a recent date.

      We are qualified to practice law in the States of Ohio, Michigan and
Nevada. We express no opinion as to, and for the purposes of the opinions set
forth herein, we have conducted no investigation of, and do not purport to be
experts on, any laws other than the laws of the State of Ohio, Michigan, Nevada
and the General Corporation Law of the State of Delaware, and to the extent
expressly set forth herein, the federal laws of the United States. This opinion
is rendered as of the date hereof, and we undertake no obligation to update this
opinion should it no longer remain accurate by change in factual circumstances,
law, judicial decision or otherwise.

      This opinion is furnished only to, and is solely for the benefit of, the
addressees named above, and except with our prior written consent, is not to be
used, circulated, quoted or otherwise referred to or disseminated for any other
purpose or relied upon by any person or entity; provided, however, that the
