We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinions set forth herein.

In addition, we have assumed that there will be no changes in applicable law between the date of this opinion and the date of issuance and delivery of the New Securities. We note that the Indenture is by its terms governed by the laws of the State of New York. We are not admitted to practice in the State of New York, and accordingly express no opinion as to the laws of such State. We express no opinion as to the validity of such choice of law. Our opinion should be understood to the effect to be given to such documents under the internal laws of the Commonwealth of Pennsylvania, if a court were to apply such law notwithstanding the parties' choice of other law. Members of our firm are admitted to the bar in the Commonwealth of Pennsylvania and we express no opinion with regard to any matter which may be governed by any law other than the federal laws of the Untied States of America and the laws of the Commonwealth of Pennsylvania. Based upon and subject to the foregoing and the limitations, assumptions, qualifications and exceptions set forth herein, we are of the opinion that when (i) the Registration Statement Philipp Brothers Chemicals, Inc. December 14, 1998 Page 4 becomes effective under the Act and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended, and (ii) the New Securities have been duly executed and authenticated in accordance with the terms of the Indenture and have been delivered upon consummation of the Exchange Offer against receipt of Old Securities surrendered in exchange therefor in accordance with the terms of the Exchange Offer, the Guarantee of the Subsidiary will constitute a valid and binding obligations of the Subsidiary, enforceable against the Subsidiary in accordance with its terms. The opinion set forth above is qualified as follows: A. The validity and enforceability of obligations, and the availability of rights and remedies, under the Indenture and under the Guarantees are subject to and may be limited or affected by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws now or hereafter in effect affecting creditors' rights, generally (including, without limitation, Section 548 of the United States Bankruptcy Code, state fraudulent transfer laws and other similar laws, relating to fraud of creditors, (ii) general principles of equity including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether such validity or enforceability of obligations or availability of rights and remedies is considered in a proceeding in equity or at law, and (iii) laws and legal principles imposing duties to act in good faith or in a commercially reasonable manner. B. The validity and enforceability of obligations, and the availability or rights and remedies, under the Indenture and the Guarantees may be further limited by other laws and judicial decisions with respect to or affecting remedial or procedural provisions contained in such documents, but in our judgment and subject to the other qualifications set forth in this letter, such other laws and judicial decisions do not render the Indenture invalid as a whole or substantially interfere with realization of the principal benefits intended to be provided thereby. C. The validity and enforceability of obligations, and the availability of rights and remedies, under the Indenture, including the Guarantees under the Indenture, may be further limited to other laws and judicial decisions with respect to the enforceability of any waiver granted under Section 6.04 of the Indenture. D. In rendering the opinion expressed in this letter, we express no opinion with respect to any provisions in the Indenture insofar as such provisions purport (i) to establish evidentiary standards or conclusive presumptions as to factual matters, Philipp Brothers Chemicals, Inc. December 14, 1998 Page 5 (ii) to appoint any person or entity as attorney-in-fact for the Subsidiary (iii) to require amendments, modifications or waivers of any provisions of the Indenture to be in writing, or (iv) to provide that any person or entity (A) may have rights to release, exculpations, indemnity or contribution, (B) may have rights to the payment or reimbursement of attorneys' fees except to the extent that a court determines that such fees are reasonable, (C) may have rights to forfeiture or the payment of any sum as liquidated, penalties, late charges or repayment premiums, (D) may have rights to any increase in any rate of interest upon delinquency in payment or the occurrence of a default, (E) may pursue inconsistent or cumulative remedies or (F) waives any right, remedy or defense.

We call to your attention that: (i) Under the laws of the Commonwealth of Pennsylvania, any provision in an agreement requiring a party to pay another party's attorneys' fees and costs in any action to enforce the provisions of such agreement will be construed to entitle the prevailing party to any such action, whether or not such party is the party specified in such agreement, to be awarded reasonable attorneys' fees, costs and necessary disbursements; and (ii) The courts of the Commonwealth of Pennsylvania will consider extrinsic evidence (both oral and written) of circumstances of the Indenture to ascertain the intent of the parties in using the language set forth in the Indenture, regardless of whether or not the language set forth in the Indenture is plain and unambiguous on its face and regardless of any statement by the parties in the Indenture that the Indenture constitutes an integrated expression of the agreement of the parties, and such courts may incorporate additional or supplementary terms into the Indenture.
