ELD offer:

(i) 0.2425 ELD share - SUBJECT TO PRO RATION
(ii) $1.2125 Cash - SUBJECT TO PRO RATION
(iii) 0.18188 ELD share plus $0.30313.

Maximum amount of cash paid by ELD is $129 million.  So everyone can't pick door #2 as you get pro rated and will be forced more ELD shares.

Option #3 seems to drive relative prices.
