In the bought deal…the buyer bought a unit @ .5, witch gave them 1 share and a warrant to purchase 1 more share @ .7 until June 30, 2011. So please tell me how this "lowered their cost basis"?

Crystallex International Corporation announced that it has completed
its previously announced financing of 70,000,000 units (the "Units") at
C$0.50 per Unit (the "Offering Price") for gross proceeds of C$35,000,000.
Each Unit consists of one common share (each, a "Common Share") and
one-half of one Common Share purchase warrant (each whole Common Share
purchase warrant, a "Warrant") of the Company. Each Warrant entitles the
holder to acquire one Common Share at a price of C$0.70 until June 30,
2011. The Units were sold on a bought deal basis by a syndicate of
underwriters led by Macquarie Capital Markets Canada Ltd., and including
GMP Securities L.P. (the "Underwriters").
