ARTICLE II REPRESENTATIONS AND WARRANTIES OF SELLER Seller represents and warrants to the Purchaser as follows: 2.1 Organization, Standing, and Qualification. Seller is a corporation duly organized, validly existing and in good standing under the laws of the State of Texas and has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as it is now being conducted. Seller is licensed and qualified to do business as a foreign corporation in each jurisdiction in which the character of Seller's properties, owned or leased, or the nature of its activities makes such qualification or license necessary, except where failure to be so licensed and qualified would not have a material adverse effect on Seller's business. 2.2 Authority; No Defaults. Seller has all requisite corporate power and authority to enter into the Transaction Documents and to consummate the transactions contemplated thereby. The execution and delivery of the Transaction Documents and the consummation of the transactions contemplated thereby have been duly authorized by all necessary corporate action on the part of Seller. The Transaction Documents have been executed and delivered by Seller and constitute the valid and binding obligation of Seller, enforceable in accordance with their terms, subject to bankruptcy, insolvency, moratorium and other similar laws affecting creditors' rights generally and general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). The execution and delivery of the Transaction Documents do not, and the consummation of the transactions contemplated hereby and thereby will not, conflict with or result in a breach of or the acceleration of any obligation under, or constitute a default or event of default (or event which, with notice or lapse of time or both, would constitute a default) under, any provision of any charter, bylaw, indenture, mortgage, lien, lease, agreement, contract, instrument, order, judgment, decree, ordinance or regulation, or any restriction to which any property of Seller is subject or by which Seller is bound, the effect of which would be materially adverse to Seller. Seller is not, nor is it alleged to be, in material violation or default of any applicable law, statute, order, rule or regulation promulgated or judgment entered by any court, administrative agency or commission or other governmental agency or instrumentality, domestic or foreign (a "Governmental Entity"), relating to or affecting the operation, conduct or ownership of the property or business of Seller. 2.3 Approvals. There is no legal impediment to the execution and delivery of the Transaction Documents by Seller or to the consummation of the transactions contemplated thereby, and no filing or registration with, or authorization, consent or approval of, a Governmental Entity, shareholders or any other third party is necessary for the consummation by Seller of the transactions contemplated thereby. 2.4 SEC Documents.

Seller has provided to the Purchaser a true, complete and correct copy of Seller's 2 3 annual report on Form 10-K for the fiscal year ended February 29, 1996 together with all amendments thereto, and any and all filings with the SEC made by Seller (including all requested exhibits to such filings) since the filing of said Form 10-K (all such documents that have been filed with the SEC, as amended, are referred to as the "Seller SEC Documents"). As of their respective dates, and except as amended, the Seller SEC Documents complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and none of the Seller SEC Documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.
