1. U2 addition to base pair with the branch site in the presence of ATP
2. U1 and U4 release Formation of the catalytic center in which U6 base pairs with the 5' splice site; U6 also base pairs with U2; U2 remains base paired with the branch site; U5 interacts with both exons through its loop.
So, 1 and 2 are the event of complex formation which are
