Disney's ROFR allows it to puchase under the same terms that the buyer must follow; adding a clause in the sale contract that would be directly applicable to Disney but not the buyer gets you nowhere as it is not binding on Disney. For example, if you agree to sell to the buyer for $10,000 and put in a clause Disney must pay $11,000 so you can recover a $1,000 commission, it has no effect on the right of first refusal and Disney's right to pay $10,000 because neither the buyer nor Disney ever agreed to pay the additional $1,000. If you could do what you suggest, Disney's ROFR would be meaningless as a seller could just as easily stick in any clause the seller wants to and make it applicable to Disney only such as that Disney must pay 4 times what the buyer agrees to pay.
