The cash consideration alternative was oversubscribed, and pursuant to the proration methodology established under the Arrangement, Orko shareholders who have elected to receive the cash consideration will receive the cash, Coeur Shares and Coeur Warrants as described above.

Pursuant to the Arrangement, Orko shareholders will receive total cash consideration of CAD$100 million, 11,572,918 Coeur Shares and 1,588,768 Coeur Warrants.
