For the avoidance of doubt it is hereby clarified that any research and development projects undertaken by Rafael merely as a subcontractor of a third party in return for cash payments (including but not limited to royalties), and specifically excluding any equity consideration, shall be deemed as development and/or research in an independent manner, excluded from the provisions of this Addendum.

Following finalization of such Business Plan and subject to RDC Approval thereof, Rafael shall engage RDC or the applicable NewCo incorporated for such purpose in an applicable License Agreement allowing the exploitation of the Specific Applications.

For the avoidance of doubt, RDC shall not be restricted in time for the preparation of such Business Plan and the obtainment of the RDC Approval in connection therewith, unless a Proposing Party approaches Rafael in connection with the same Specific Applications as provided in Section 7.3.4 below prior to finalization of RDC’s Business Plan, in which event RDC shall have up to an additional 60 days to finalize its Business Plan and obtain the RDC Approval, commencing from Rafael’s notice to RDC of such Proposing Party.

In the event that RDC shall notify Rafael in writing that it is not interested in the commercial exploiting of the relevant Specific Applications, then Rafael shall be at liberty to exploit commercialization of such Specific Applications based on the applicable Other Technologies with third parties, without any further obligation and/or recourse to any of the other parties hereunder with respect to such Specific Applications.

Without derogating from the foregoing, RDC shall use its bona fide best efforts to expedite the preparation of the Business Plan and the obtainment of the RDC Approval, so as to minimize any adverse effect on any possible future utilization of the relevant Technology by Rafael.

Following finalization of such Business Plan and subject to RDC Approval therefor, Rafael shall engage RDC or the applicable NewCo incorporated for such purpose by an applicable License Agreement, allowing the exploitation of the Specific Applications.

RDC shall then have the right to notify Rafael in writing within the next 60 days of RDC Approval regarding such venture based on the provisions of the Business Plan proposed by the Proposing Party; unless RDC has previously commenced working on its own Business Plan, in such event the provisions of either Sections 7.3.2 or 7.3.3 above, as the case may be, shall prevail (and accordingly, any reference to the RDC Approval shall apply to RDC’s Business Plan, and the remaining provisions of this Section 7.3.5 below shall not apply).

Following RDC Approval, based on the Proposing Party’s Business Plan, one of the following shall apply:

Following receipt of RDC Approval as provided above, Rafael shall engage RDC or the applicable NewCo incorporated for such purpose by an applicable License Agreement allowing the exploitation of the Specific Applications (whether the venture is between RDC and Rafael, or between RDC and the Proposing Party, as the case may be).

If RDC shall not notify Rafael within 60 days of RDC Approval regarding the venture proposed by the Proposing Party as provided above, Rafael shall be at liberty to enter into collaboration with the Proposing Party without any further obligation and/or recourse to any of the other parties hereunder with respect to the Specific Applications based on the Other Technologies as set forth in the Proposing Party’s Business Plan,provided however, that if a Material Change to a Business Plan shall occur with respect to the venture proposed by the Proposing Party, Rafael shall be required to offer RDC to participate in such venture again, and the provisions of this Section 7.3.4 shall apply,mutatis mutandis.

Upon the written consent of RDC and DEP, the Management Fee payable pursuant to an IPO will be payable in securities, rather than cash.

| | (Y) | If the Exit Consideration is received in securities of another company which are not publicly traded, or otherwise are subject to any lock-up or similar restriction (‘‘Restricted Securities’’), then such Management Fee shall be payable to DEP only upon the earlier of the following: (A) such Restricted Securities will be sold in consideration for cash or asset or securities other than Restricted Securities, or (B) RDC shall have first sold such Restricted Securities pursuant to a public offering, or (C) the lock-up or similar restrictions applicable to such Restricted Securities shall have expired.

For the avoidance of any doubt, the Management Fee shall be calculated according to the value of the original Exit Consideration and will not be affected by the deferred payment hereunder.
