¹ Pro rata portion of 35% among investors executing Leak-Out Agreements, based on aggregate Purchase Price.

Notwithstanding anything herein to the contrary, during the Restricted Period, the Holder may, directly or indirectly, sell or transfer all, or any part, of the Shares or the Warrant Shares (the “Restricted Securities”) to any Person (an “Assignee”) without complying with (or otherwise limited by) the restrictions set forth in this Leak-Out Agreement, provided that, as a condition to any such sale or transfer an authorized signatory of the Company and such Assignee duly execute and deliver a leak-out agreement in the form of this Leak-Out Agreement (an “Assignee Agreement”, and each such transfer a “Permitted Transfer”), provided that the Leak-Out Percentage as to such Assignee and the Leak-Out Percentage of the assignor shall be proportionally adjusted based on the original leak-Out Percentage of the Holder.

Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Leak-Out Agreement must be in writing and shall be given in accordance with the terms of the Subscription Agreement.

This Leak-Out Agreement constitutes the entire agreement among the parties hereto with respect to the subject matter hereof and supersedes all prior negotiations, letters and understandings relating to the subject matter hereof and are fully binding on the parties hereto.

This Leak-Out Agreement may be executed simultaneously in any number of counterparts. Each counterpart shall be deemed to be an original, and all such counterparts shall constitute one and the same instrument.

This Leak-Out Agreement may not be amended or modified except in writing signed by each of the parties hereto.

All questions concerning the construction, validity, enforcement and interpretation of this Leak-Out Agreement shall be governed by Section 10 of Annex I to the Subscription Agreement.

Each party hereto acknowledges that, in view of the uniqueness of the transactions contemplated by this Leak-Out Agreement, the Company may not have an adequate remedy at law for money damages in the event that this Leak-Out Agreement has not been performed in accordance with its terms, and therefore agrees that the Company shall be entitled to seek specific enforcement of the terms hereof in addition to any other remedy it may seek, at law or in equity.

Without implication that the contrary would otherwise be true, the Company acknowledges and agrees that this Leak-Out Agreement is a separate agreement that is solely between the Company and the undersigned and not between or among any other person or entity.
