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 certified, facsimile, conformed or photostatic copies and the authenticity of the originals of such latter documents. In making our examination of documents executed or to be executed by parties other than the Company and the Delaware Subsidiaries, we have assumed that such parties 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 the validity and binding effect of such documents on such parties.

We have also assumed that the execution and delivery by the Company and the Guarantors of the Securities, the Registration Rights Agreements and the Indentures and the performance by the Company and the Guarantors of their respective obligations thereunder do not and will not violate or constitute a default under (i) any agreement or instrument to which the Company, the Guarantors or any of their properties is subject, (ii) any law, rule or regulation to which the Company and the Guarantors are subject, (iii) any judicial or regulatory order or decree of any governmental authority or (iv) any consent, approval, license, authorization or validation of, or filing, recording or registration with any governmental authority. Our opinions are also subject to the qualification that certain of the remedial provisions and waivers with respect to the Guarantees contained in the Indentures may be unenforceable in whole or in part, but the inclusion of such provisions should not affect the validity of the Guarantees, each taken as a whole, and each of the Guarantees, each taken as a whole, together with applicable law, contains adequate provisions for the practical realization of the benefits of the guarantee created thereby. 5 Hayes Wheels International, Inc. September 12, 1997 Page 5 Members of this firm are admitted to the Bar in the State of New York, and we do not express any opinion as to the laws of any other jurisdiction other than the General Corporation Law of the State of Delaware.
