Under the terms of this agreement, the licensor must obtain all of the following milestones in order for the Company to earn the revenues. These milestones are a) the receipt of an approvable letter from the FDA, b) acknowledgment from the FDA that no further clinical studies will be needed and c) an approval letter from the FDA. If these milestones are not met, then the $6,000,000 in total included in deferred revenue on the balance sheet at March 31, 2014 and September 30, 2013 must be refunded and the product rights are returned to the Company. In addition, the Company may receive additional milestones of up to $3,000,000 in the future, dependent on the licensor's actively selling the product in an exclusive market position.
