EFFECT OF MERGER ON CONVERSION PRIVILEGE

Section 2.01. Agreement of Parties.

(a) From and after the Effective Time (as defined in the Merger Agreement), each Holder of a Security that was outstanding immediately prior to the Effective Time shall have the right to convert each $1,000 principal amount of such Security into the amount of cash equal to the Cash Component of the Old Reference Property and Parent Common Stock that a holder of shares of Company Common Stock equal to the Conversion Rate (as adjusted pursuant to the Indenture, including to take into account the conversion into Old Reference Property) immediately prior to the Merger would have received in the Merger, subject to the Company’s right to elect to pay cash upon such a conversion as provided in Section 10.02 of the Indenture (such cash and Parent Common Stock, the “New Reference Property”).
