(a) The adjusted conversion price input used in the Binomial Lattice Model considers both (i) the reduction of the conversion price to $0.675 on April 30, 2015, as result of a private placement offering in which Common Stock was sold for a weighted average price of $0.75 and (ii) potential adjustment to the stated conversion price due to a future dilutive issuance. This input was calculated using a probability-weighted approach which considered the likelihood of various scenarios occurring including (i) potential success or failure of various phases for PRO 140, (ii) the probability the Company will enter into a future financing and (iii) and the potential price of a future financing.
