Up to $106,003,000 principal amount of New Notes will be issued in exchange (the "Exchange Offer") for a like principal amount of the Company's outstanding 14.25% Series A Second Priority Senior Secured Notes due 2007 (PIK through April 1, 2000) (the "Old Notes"), and up to $7,553,000 principal amount of additional New Notes will be issued in lieu of the April 1, 2000 cash interest payment on the New Notes. In so acting, we have examined originals or copies of the (1) the Registration Statement; (2) the Prospectus that is a part of the Registration Statement (the "Prospectus"); (3) the Indenture; and (4) the Registration Rights Agreement dated as of October 26, 1999 by and among the Company, the Guarantors and the Purchasers and Exchanging Noteholders (as defined therein). 2 Anker Coal Group, Inc. February 4, 2000 Page 2 We have also examined original, reproduced or certified copies of resolutions adopted by the Company's and the Guarantors' boards of directors and such other documents, corporate records, certificates of public officials, officers and representatives of the Company and other instruments as we have deemed necessary or appropriate to render the opinions set forth below, and have considered such questions of law as we have deemed necessary to enable us to render the opinions expressed below. In our examination of documents and records, we have assumed, without investigation, the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity with originals of all documents submitted to us as telecopied, certified, photostatic or reproduced copies and the authenticity of all such documents. We have also assumed, but not independently verified, that all documents executed by a party other than the Company or the Guarantors were duly and validly authorized, executed and delivered by such party, that such party has the requisite power and authority to execute, deliver and perform such agreements and other documents, and that such agreements and other documents are legal, valid and binding obligations of such party and enforceable against such party in accordance with their respective terms. This opinion is limited to the federal laws of the United States of America, the laws of the state of New York, and the general corporation law of the State of Delaware. In this regard, we note that many of the Guarantors are incorporated in West Virginia and one of the Guarantors is incorporated in Virginia. For purposes of our opinion herein, we have assumed that the laws of West Virginia and Virginia are each identical in all relevant respects to the general corporation law of Delaware. We express no opinion whatsoever as to the laws or regulations of any other jurisdiction or as to laws relating to choice of law or conflicts of law principles. Based upon the foregoing, subject to the assumptions, limitations and exceptions contained herein, and subject to the issuance by the Commission of an order declaring the Registration Statement effective, we are of the opinion that, when the New Notes and the Guarantees, in the forms filed as exhibits to the Indenture, have been duly executed and authenticated in accordance with the Indenture and have been duly issued and delivered in exchange for an equal principal amount of Old Notes pursuant to the terms of the Indenture and the Exchange Offer or in payment of the April 1, 2000 interest payment on the New Notes, the New Notes and the Guarantees will (x) be the legal and binding obligations of the Company and the Guarantors enforceable against the Company and the Guarantors, as the case may be, in accordance with their terms except as (a) the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting creditors' rights generally, and (b) rights of acceleration, if applicable, and the availability of equitable remedies may be limited by equitable principles of general applicability, as well as concepts of materiality, reasonableness, good faith and fair dealing, and (y) be entitled to the benefits of the Indenture. 3 Anker Coal Group, Inc.
