Each whole Series A warrant entitles the holder to purchase 0.543 of a Yamana common share and receive 0.1 cent cash per warrant exercised, at a price of $2 at any time before 4 p.m. (Vancouver time) on May 29, 2008.
Each whole Series B warrant entitles the holder to purchase 0.543 of a Yamana common share and receive 0.1 cent cash per warrant exercised, at a price of $6 at any time before 4 p.m. (Vancouver time) on Feb. 17, 2010.
Certificates representing each series of Northern Orion Resources Inc. warrants (from which the Series A warrants and the Series B warrants were derived) will represent good delivery until replaced against transfer.
Fractional Yamana common shares will not be issued upon exchange of either the Series A warrants or the Series B warrants. The number of Yamana common shares to which the holder of Series A warrants or Series B warrants is otherwise entitled on exercise will be rounded down to the nearest whole number.
The Series A warrants and Series B warrants reflect the obligation of Yamana, pursuant to the recently effected plan of arrangement involving Northern Orion and Yamana to issue Yamana common shares upon valid exercise.
The Series A warrants are governed by the terms of a warrant indenture dated May 29, 2003, between Northern Orion and Pacific Corporate Trust Co. (PCTC), as trustee and a supplemental warrant indenture, dated Oct. 13, 2007, between Yamana and PCTC. The Series B warrants are governed by the terms of a warrant indenture dated Feb. 17, 2005, between Northern Orion and PCTC, as trustee, and a supplemental warrant indenture dated Oct. 13, 2007, between Yamana and PCTC. Each indenture provides, among other things, for appropriate adjustments to be made to the warrants in the event of stock dividends, subdivisions, consolidations and other forms of capital reorganization.
