Based upon the foregoing, we are of the following opinion: When (a) the U.S. Bank Trust Indenture, under which the Securities will be issued, has been qualified under the Trust Indenture Act of 1939, as amended, (b) the Exchange Notes have been executed by the Company and the Guarantees have been executed by each of the Guarantors and (c) the Securities have been delivered in exchange for the Old Notes and the related guarantees endorsed thereon in the manner stated in the Registration Statement and the U.S. Bank Trust Indenture, the Securities will be validly issued, fully paid and non-assessable, and will be binding obligations of the Company (in the case of the Exchange Notes) and the Guarantors (in the case of the Guarantees), except as may be limited by: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights or remedies of creditors; (ii) the effect of general principles of equity, including (without limitation) concepts of materiality, reasonableness, good faith and fair dealing, regardless of whether the application of such principles is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought; and (iii) the unenforcebility under certain circumstances, as contrary to public policy, under law or court decisions of provisions providing for the indemnification or exculpation of, or contribution to, a party. We express no opinion as to the validity, binding effect or enforceability of any provision of the Exchange Notes or the Guarantees: (1) relating to indemnification or contribution; (2) containing any purported waiver, release, variation, disclaimer, consent or other agreement of similar effect (all of the foregoing, a "Waiver") by the Company or any Guarantor under any of such agreements to the Board of Directors Speedway Motorsports, Inc. June 16, 1999 Page 3 extent limited by provisions of applicable law (including judicial decisions), or to the extent that such a Waiver applies to a right, claim, duty, defense or ground for discharge otherwise existing or occurring as a matter of law (including judicial decisions), except to the extent that such a Waiver is effective under, and is not prohibited by or void or invalid under provisions of applicable law (including judicial decisions), or any Waiver in the Guarantee insofar as it relates to causes or circumstances that would operate as a discharge or release of, or defense available to the Guarantors thereunder as a matter of law (including judicial decisions), except to the extent such Waiver is effective under and is not prohibited by or void or invalid under applicable law (including judicial decisions); (3) relating to choice of governing law to the extent that the validity, binding effect or enforceability of any such provision is to be determined by any court other than a court of the State of New York or a federal district court sitting in the State of New York and applying the law of the State of New York; (4) specifying that provisions thereof may be waived only in writing, to the extent that an oral agreement or an implied agreement by trade practice or course of conduct has been created that modifies any provision of such agreement; (5) purporting to give any person or entity the power to accelerate obligations without any notice to the obligor; (6) purporting to give any party conclusive rights of determination; (7) purporting to make specific performance or other equitable remedies available; (8) relating to reimbursement of legal fees; and (9) purporting to allow for the payment of liquidated damages by any person, to the extent such liquidated damages may be determined to be unreasonable. In addition to the foregoing, our opinions expressed herein are subject to the following qualifications: (a) provisions in the Guarantees that provide that the Guarantors' liability thereunder shall not be affected by actions or failures to act on the part of the holders or the Trustee or by amendments or waivers of provisions of documents governing the guaranteed obligations might not be enforceable under circumstances and in the event of actions that change the essential nature of the terms and conditions of the guaranteed obligations; (b) we express no opinion as to whether the Guarantee would be deemed by a court of competent jurisdiction to be within the authorized corporate power of any Guarantor; and (c) we have assumed consideration that is fair and sufficient to support the agreements of each Guarantor under the Guarantee has been, and would be deemed by a court of competent jurisdiction to have been, duly received by each Guarantor. The opinions expressed herein are limited to matters governed by the laws of the States of North Carolina and New York, the General Corporation Law of the State of Delaware, the Act and the applicable business corporation or limited liability company laws, as applicable, of the States of Georgia (as to Atlanta Motor Speedway, Inc.), Tennessee (as to Bristol Motor Speedway, Inc.), Texas (as to Texas Motor Speedway, Inc.), California (as to SPR Acquisition Corporation and Sonoma Funding Corporation) and Nevada (as to Las Vegas Motor Speedway, LLC and SMI Systems, LLC); and with respect to such laws of Georgia, Tennessee, Texas, California and Nevada, our opinions are based solely on our reading, as North Carolina lawyers, of unofficial compilations of the corporate or limited liability company statutes of such states available to us.
