Ladies and Gentlemen:
 
     We refer to the Registration Statement on Form S-3 (the 'Registration
Statement') under the Securities Act of 1933, as amended (the 'Securities Act'),
in the form in which it is to be filed today by Union Camp Corporation, a
Virginia corporation ('Union Camp'), with the Securities and Exchange Commission
(the 'Commission'), relating to up to $400,000,000 aggregate principal amount of
Union Camp's debt securities consisting of debentures, notes or other unsecured
evidences of indebtedness (the 'Securities') to be issued from time to time
pursuant to the terms of an Indenture, dated as of November 1, 1994,
between Union Camp and The Bank of New York, as successor to NationsBank of
Georgia, National Association, as Trustee, filed as Exhibit 4 to the
Registration Statement (the 'Indenture'), and to be sold to or through
underwriters, to other purchasers or through agents. The terms of the Securities
are to be approved and the manner of sale is to be determined in additional
proceedings proposed to be taken by a committee of Union Camp's Board of
Directors.
 
     We have examined the originals, or photostatic or certified copies, of such
records of Union Camp, certificates of officers of Union Camp and of public
officials and such other documents as we have deemed relevant and necessary as
the basis for the opinion set forth below. We have relied upon such certificates
of public officials and such certificates of officers of Union Camp and
statements and information furnished by officers of Union Camp with respect to
the accuracy of material factual matters contained therein which were not
independently established. In such examination we have assumed the genuineness
of all signatures, the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to us
as photographic or certified copies, and the authenticity of the originals of
such copies.
 
     Based upon our examination mentioned above, subject to the assumptions
stated, and subject to such proposed additional proceedings being taken prior to
the issuance of the Securities and to the terms of the Securities being
otherwise in compliance with then applicable law, it is our opinion that the
Securities, upon issuance and sale by Union Camp as contemplated in the
Registration Statement and any amendments and Prospectus Supplements thereto,
will have been duly authorized by Union Camp and that the Securities, when duly
executed, authenticated, issued and delivered against payment therefore in
accordance with the Indenture, will constitute valid and legally binding
obligations of Union Camp.
 
     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to our firm appearing under the caption 'Legal
Matters' in the Prospectus forming part of the Registration Statement. In giving
this consent, we do not thereby admit that we are within the category of persons
whose consent is required under Section 7 of the Securities Act or the Rules and
Regulations of the Commission.
 
                                          Very truly yours,
 
 
                                          WHITE & CASE
