Upon the exercise of the Additional Option by Eldorado, the Company will have a 20% undivided beneficial interest in the Properties and Eldorado will have an 80% undivided beneficial interest in the Properties, after which the parties will contribute their proportional share to further exploration and development of the Properties, subject to standard dilution.
