This First Amendment is dated as of February 20, 1998. Capitalized terms used herein but not defined shall have the meanings assigned to such terms in the Rights Agreement. R E C I T A L S WHEREAS, the Company and the Rights Agent have heretofore executed the Rights Agreement; and WHEREAS, the Company desires to amend the Rights Agreement to revise Section 1(p) thereof; NOW, THEREFORE, in consideration of the premises and the mutual agreements herein set forth and in accordance with Section 27 of the Rights Agreement, the parties hereby agree as follows: 1. Section 1(p) of the Rights Agreement is hereby amended, effective as of the date set forth above, by revising such Section to read in its entirety as follows: "Exempt Person" shall mean (i) the Company or any Subsidiary (as such term is hereinafter defined) of the Company or any employee benefit plan of the Company, (ii) James C. Flores, his spouse, lineal descendants and ascendants, heirs, executors or other legal representatives and any trusts established for the benefit of the foregoing, or any other person or entity in which the foregoing persons or entities are at the time of determination the direct record and beneficial owners of all outstanding voting securities (each a "Flores Stockholder") or (iii) any Person that is not a Flores Stockholder but who or which is the Beneficial Owner of Common Stock Beneficially Owned by a Flores Stockholder (a "Second Tier Flores Stockholder"), but only if the shares of Common Stock otherwise Beneficially Owned by such Second Tier Flores Stockholder ("Second Tier Holder Shares") do not exceed the sum of 2 (A) such holder's Second Tier Holder Shares held on the date hereof and (B) 1% of the shares of Common Stock of the Company then outstanding; provided, however, that in the event that James C.

The adjustments provided for in this Section 11(n) shall be made successively whenever such a dividend is declared or paid or such a subdivision, combination or consolidation is effected. 3.
