WITNESSETH:

WHEREAS, the Parties have entered into the Agreement; and

WHEREAS, the Parties hereto wish to waive certain covenants and closing conditions under the Agreement as set forth in this Waiver.

NOW, THEREFORE, in consideration of the rights and obligations contained herein, and for other good and valuable consideration, the adequacy of which is hereby acknowledged, the Parties agree as follows:

1. Waiver: So long as Nasdaq, as of immediately prior to the Effective Time, shall have neither (i) provided its approval of Newco’s initial Listing Application with Nasdaq nor (ii) indicated to any Party or such Party’s respective Affiliates that approval of Newco’s initial Listing Application would be given prior to Acquiror’s liquidation, dissolution and winding up in accordance with the Governing Documents of Acquiror, the Parties hereby irrevocably waive the following conditions to Closing set forth in Section 7.3(d) of the Agreement: that, immediately following the Effective Time (A) Newco shall be in compliance with any applicable initial and continuing listing requirements of Nasdaq; (B) Newco shall not have received any notice of non- compliance therewith that has not been cured or would not be cured; and (C) the Newco Shares included in the Listing Application shall have been approved for listing on Nasdaq. For the avoidance of doubt, in the event that either condition in the foregoing clauses (i) or (ii) is not satisfied as of immediately prior to the Effective Time, then each of the conditions to Closing set forth in Section 7.3(d) of the Agreement shall remain in full force and effect.

2. Parties in Interest. This Waiver shall be binding upon and inure solely to the benefit of each Party hereto, and nothing in this Waiver, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Waiver.

3. Entire Agreement. This Waiver constitutes the entire agreement among the Parties with respect to the subject matter hereof and supersedes all prior agreements and undertaking, both written and oral, among the Parties, or any of them, with respect to the subject matter hereof.

4. Counterparts. This Waiver may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in one or more counterparts, and by the different Parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

5. Governing Law. This Waiver shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed in that State.
