The Stockholder shall have 15 Business Days from the date of the Notice of Issuance to agree to purchase all or any portion of such Stockholder's pro rata share of such New Securities (as determined pursuant to Section 6.05(a)) for the same pro rata consideration payable by such other Person at the time of payment and otherwise upon the terms specified in the Notice of Issuance, by giving written notice to 3 3 the Company and stating therein the quantity of New Securities to be purchased by such Stockholder.

In addition, you hereby agree to amend the Stockholders' Agreement by adding a new Section 6.06 to read in its entirety as follows: "SECTION 6.06. Non-Pro Rata Recapitalizations; Stock Repurchases: Dividends and Distributions.
