In January 2015, the Company completed the sale of its Tempus^™ Cervical Plate product line, which was part of the Company’s Spine Fixation SBU. The sale included the transfer of net assets of $2.1 million, consisting of intellectual property and the associated inventory, in exchange for consideration of $4.8 million in cash. On March 4, 2015, the Company entered into an Option Agreement (the “Option Agreement”) with eNeura, Inc. (“eNeura”), a privately held medical technology company that is developing devices for the treatment of migraines. The Option Agreement provides the Company with an exclusive option to acquire eNeura (the “Option”) during the 18-month period following the grant of the Option. In consideration for the Option, (i) the Company paid a non-refundable $250,000 fee to eNeura, and (ii) eNeura issued a Convertible Promissory Note (the “eNeura Note”) to the Company. The principal amount of the eNeura Note is $15,000,000 and interest will accrue at 8%. The eNeura Note will mature on the earlier of (i) March 4, 2019, or (ii) consummation of the acquisition (as described below), unless converted or prepaid at an earlier date. The Company will be entitled to designate one representative for appointment to the board of directors of eNeura during the 18-month option period. Pursuant to an Agreement and Plan of Merger between the Company, eNeura and certain other parties, if the Company exercises the Option to acquire eNeura, the Company will pay to former eNeura shareholders $65 million (subject to certain positive or negative adjustments based on the assets and liabilities of eNeura). In addition, during the 4-year period following the closing of such acquisition, the Company may be required to pay additional cash consideration to eNeura shareholders upon the satisfaction of certain milestones.
