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 KK:JHD:JG
