probably warren holders who sell their shares to keep the...probably warrant holders who sell half of their shares to keep the warrent.
so it's warrent holder can buy other shares with the same money.
this is the most logical reason,
Each Unit shall consist of one common share of the Company (a "Common Share") and one-half of one common share purchase warrant of the Company (each whole warrant, a "Warrant"). Each Warrant will be exercisable to acquire one Common Share for a period of 12 months following the closing of the Offering at an exercise price of $1.60 per share.
