J. Subsequent Event:

On April 1, 2014, the Company entered into an Agreement of Investment and Merger (the Agreement) with CyVek, Inc. (CyVek). Pursuant to the terms of the Agreement, the Company invested $10.0 million in CyVek and received shares of Common Stock representing approximately 20% of the outstanding voting stock of CyVek.

If, within twelve months of the date of the Agreement, CyVek meets commercial milestones related to the sale of its products, the Company will acquire CyVek through a merger, with CyVek surviving as a wholly-owned subsidiary of the Company. If the Merger is consummated, the Company will make an initial payment of $60.0 million to the other stockholders of CyVek. The purchase price payable at the closing of the Merger may be adjusted based on the final levels of cash, indebtedness and transaction expenses of CyVek as of the closing. The Company will also pay CyVek’s other stockholders up to $35.0 million based on the revenue generated by CyVek’s products and related products before the date that is 30 months from the closing of the Merger. The Company will also pay CyVek’s other stockholders 50% of the amount, if any, by which the revenue from CyVek’s products and related products exceeds $100 million in calendar year 2020.
