You sound outraged, unless I'm misreading your exclamation points. Why? Of course they intend to purchase their full allocation as should any and all shareholders (once the DA is signed). To not do so would dilute your investment. And if they did not intend to excercise these rights, that would send a pretty ugly signal.

If they the DA is not signed before the expiration of the rights, I'm confident that management will extend the rights ... there wouldn't be a reason NOT to.
