In April 2015, the Company acquired 100% of Okanagan Specialty Fruits Inc.

In March 2015, the Company signed a worldwide License and Collaboration Agreement ("Merck Agreement") with Ares Trading S.A. ("Ares Trading"), a subsidiary of the biopharmaceutical business of Merck KGaA, and ZIOPHARM through which the parties established a collaboration for the research and development and commercialization of certain products for the prophylactic, therapeutic, palliative or diagnostic use for cancer in humans. The Company expects the Merck Agreement to become effective in the second quarter following regulatory approval. Pursuant to the Merck Agreement, the Company will receive an upfront fee of $115,000, up to $826,000 of potential payments for development and commercial milestones for the first two products, and royalties ranging from the lower-single digits to the lower-double digits of the net sales derived from the sale of products developed under the Merck Agreement. The Company may also receive further cash fees upon certain technical milestones as provided for in the agreement as well as in the event that Ares Trading selects additional targets beyond the initial two targets. In conjunction with the Merck Agreement, the Company and ZIOPHARM amended their existing ECC (Note 5). The amendment modifies the scope of the ECC in connection with the Merck Agreement and provides that the Company will pay to ZIOPHARM 50% of all payments received for upfront fees, milestones and royalties under the Merck Agreement. The amendment also reduces the Company's commitment to purchase $50,000 of ZIOPHARM common stock (Note 17) to $43,500, which commitment has been satisfied as of March 31, 2015.
