The Indenture dated as of May 16, 2003 (the "Indenture"), between the Company, the Guarantors and Bank One, N.A., as Trustee (the "Trustee"), provides for the guarantee of the Exchange Notes by the Guarantors (the "Guarantees") to the extent set forth in the Indenture. The Exchange Notes are to be issued pursuant to an exchange offer (the "Exchange Offer") in exchange for a like principal amount of the issued and outstanding 12% Senior Second Secured Notes due 2010 of the Company (the "Original Notes") under the Indenture, as contemplated by the Registration Rights Agreement, dated as of May 16, 2003 (the "Registration Rights Agreement"), by and among the Company, the Guarantors, Morgan Stanley & Co. Incorporated, Merrill Lynch, Pierce, Fenner & Smith Incorporated and PNC Capital Markets, Inc. This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended (the "Act"). In rendering the opinions set forth herein, we have examined originals or copies of the following: (i) the Registration Statement on Form S-4 relating to the Exchange Notes and the Guarantees filed with the Securities and Exchange Commission (the "Commission") on October 10, 2003 under the Act (the "Registration Statement"); (ii) an executed copy of the Registration Rights Agreement; (iii) an executed copy of the Indenture including the terms and provisions of the Guarantees; (iv) the Certificate of Incorporation of Sys-tems LogistiX, Inc. ("Sys-tems"), as amended by the Certificate of Amendment of Certificate of Incorporation of Sys-tems and as certified by the Secretary of State of the State of Delaware; (vi) the Certificate of Incorporation of Evergreen Aviation Ground Logistics Enterprises, Inc. ("EAGLE", together with Sys-tems, the "Delaware Guarantors"), as amended by the Certificate of Amendment of Certificate of Incorporation of EAGLE and as certified by the Secretary of State of the State of Delaware; (v) the Amended and Restated By-Laws of each of the Delaware Guarantors, as currently in effect; (vi) certain resolutions adopted by the Board of Directors of each of the Delaware Guarantors relating to the Exchange Offer, the Indenture, the issuance of the Guarantees by the Delaware Guarantors and related matters; and (vii) the form of the Exchange Notes. We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and the Guarantors and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company, the Guarantors and others, and such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinions set forth herein. In our examination, we have assumed the legal capacity of all natural persons, 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 facsimile, electronic certified, conformed or photostatic copies and the authenticity of the originals of such copies. In making our examination of executed documents or documents to be executed, we have assumed that the parties thereto (including the Company), other than the Delaware Guarantors, had or will have the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and execution and delivery by such parties of such documents and, except as set forth in our opinion below, the validity and binding effect on such parties. We have also assumed that the Company and each of the Guarantors, other than the Delaware Guarantors, has been duly organized and is validly existing in good standing under the laws of its respective jurisdiction of organization and that the Company and each of the Guarantors, other than the Delaware Guarantors, has complied with all aspects of applicable laws of jurisdictions other than the United States of America and the State of New York in connection with the transactions contemplated by the Exchange Notes, the Guarantees, the Registration Rights Agreement and the Indenture. In addition, we have assumed that the execution and 2 delivery by the Company and the Guarantors of the Indenture, the Exchange Notes and the Guarantees and the performance by the Company and the Guarantors of their respective obligations thereunder do not and will not violate, conflict with or constitute a default under any agreement or instrument to which the Company or the Guarantors or their properties are subject. As to any facts material to the opinions expressed herein which we have not independently established or verified, we have relied upon statements and representations of officers and other representatives of the Company, the Guarantors and others. Our opinions set forth herein are limited to Delaware corporate law and the laws of the State of New York that, in our experience, are applicable to securities of the type covered by the Registration Statement and, to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws (all of the foregoing being referred to as "Opined on Law"). We do not express any opinion with respect to the law of any jurisdiction other than Opined on Law or as to the effect of any such non opined law on the opinions herein stated. Based upon and subject to the foregoing and the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that when the Exchange Notes (in the form examined by us) 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 Original Notes surrendered in exchange therefor in accordance with the terms of the Exchange Offer, the Exchange Notes and the Guarantees will constitute binding obligations of the Company and each of the Guarantors, respectively, enforceable against the Company and each of the Guarantors, respectively, in accordance with their terms, except to the extent that enforcement thereof may be limited by (1) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws now or hereafter in effect relating to creditors' rights generally and (2) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity). We hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement. We also consent to the reference to our firm under the caption "Legal Matters" in the Registration Statement. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission.
