This is a question on my final study prep right now! I need help! A paragraph answer of opinion and legal terms / ethical theories?

Question:

Some minority DULL shareholders objected strongly against a merging of the DULL and Exciting corporations, as they had been convinced that DULL's future was bright and would be worth far more once its current precarious financial situation was resolved. Now that the merger has been completed, despite their objections, what rights do these shareholders have?
