There are two line items addressed in the amendment. There is paragraph (a) of the amendment, which adds something after line 21, and paragraph (b) of the amendment, which adds something after line 30.
I believe Mr. McLean's amendment addresses paragraph (b) by essentially deleting paragraph (b), so all that would remain is the part that adds, after line 21, all of the text in paragraph (a).
I hope that's helpful.
