Amendment of Material Definitive Agreement

As previously disclosed, on January 16, 2015 CollabRx, Inc. (“CollabRx” or the “Company”) entered into (i) a Loan and Security Agreement (the “Loan Agreement”) with Medytox Solutions, Inc. (“Medytox”), pursuant to which it is contemplated that Medytox will loan up to $2,395,644 to CollabRx and (ii) an Agreement (the “Agreement”) with Medytox, pursuant to which CollabRx agreed that in the event it enters into a merger or other sale transaction involving at least thirty-five percent (35.0%) of its shares or assets with a party other than Medytox (a “Sale Transaction”), CollabRx will pay Medytox a $1,000,000 fee (the “Fee”). On February 19, 2015, CollabRx and Medytox entered into an amendment to the Loan Agreement and the Agreement (the “Amendment”) clarifying that, subject to certain exceptions, (i) the Offering (as detailed below) would not constitute a Sale Transaction for purposes of the Agreement and (ii) the Offering will not constitute a change in control of CollabRx or a breach of CollabRx’s convenant to conduct its business in the ordinary course pursuant to the Loan Agreement. Additionally, the Amendment sets forth CollabRx’s agreement not to request any further advances from Medytox pursuant to the Loan Agreement until after it has spent at least the greater of (i) $1,500,000 of the proceeds of the Offering or (ii) 60% of the net proceeds of the Offering. The full text of the Amendment is filed as Exhibit 10.1 to this Current Report and incorporated herein by this reference. The description of the Amendment provided above is qualified in its entirety by the full text as attached.
