Fannie Mae Preferred S (FNMAS)

"Otherwise, we may amend the CertiÑcate of Designation only with the consent of the holders
of at least two-thirds of the outstanding shares of Preferred Stock. On matters requiring consent,
each holder will be entitled to one vote per shar"

Interesting, so conversion would require preferred stockholders voting with 2/3 majority. Also, vote is per share, so 50 dollar jrs also get 1 vote and so do 25 dollar jrs (rather that 2 to 1).
What voting rights do Sr's Pref get in this?
