 NOW, THEREFORE, in consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and intending to be legally bound hereby, the parties hereby agree as follows:

1 

1.Lock-Up Provisions.

(a)Holder hereby agrees not to, during the period (the “Lock-Up Period”) commencing from the Closing and ending on the earlier of (x) the one (1) year anniversary of the date of the Closing, (y) the date on which the closing price of the Purchaser Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any twenty (20) trading days within any thirty (30) trading day period commencing at least one-hundred fifty (150) days after the Closing, and (z) the date after the Closing on which Purchaser consummates a liquidation, merger, share exchange or other similar transaction with an unaffiliated third party that results in all of Purchaser’s stockholders having the right to exchange their equity holdings in Purchaser for cash, securities or other property: (i) lend, offer, pledge, hypothecate, encumber, donate, assign, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any Restricted Securities, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Restricted Securities, or (iii) publicly disclose the intention to do any of the foregoing, whether any such transaction described in clauses (i), (ii) or (iii) above is to be settled by delivery of Restricted Securities or other securities, in cash or otherwise (any of the foregoing described in clauses (i), (ii) or (iii), a “Prohibited Transfer”). The foregoing sentence shall not apply to the transfer of any or all of the Restricted Securities owned by Holder (other than any Escrow Shares until such Escrow Shares are disbursed to Holder from the Escrow Account in accordance with the terms and conditions of the Merger Agreement and the Escrow Agreement) (I) by gift, will or intestate succession upon the death of Holder, (II) to any Permitted Transferee (as defined below) or (III) pursuant to a court order or settlement agreement related to the distribution of assets in connection with the dissolution of marriage or civil union; provided, however, that in any of cases (I), (II) or (III) it shall be a condition to such transfer that the transferee executes and delivers to the Purchaser and the Purchaser Representative an agreement stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of this Agreement applicable to Holder, and there shall be no further transfer of such Restricted Securities except in accordance with this Agreement. As used in this Agreement, the term “Permitted Transferee” shall mean: (A) the members of Holder’s immediate family (for purposes of this Agreement, “immediate family” shall mean with respect to any natural person, any of the following: such person’s spouse, the siblings of such person and his or her spouse, and the direct descendants and ascendants (including adopted and step children and parents) of such person and his or her spouses and siblings), (B) any trust for the direct or indirect benefit of Holder or the immediate family of Holder, (C) if Holder is a trust, the trustor or beneficiary of such trust or to the estate of a beneficiary of such trust, (D) if Holder is an entity, as a distribution to limited partners, shareholders, members of, or owners of similar equity interests in Holder upon the liquidation and dissolution of Holder, and (E) any affiliate of Holder. Holder further agrees to execute such agreements as may be reasonably requested by Purchaser or the Purchaser Representative that are consistent with the foregoing or that are necessary to give further effect thereto.

(b)Holder further acknowledges and agrees that it shall not be permitted to engage in any Prohibited Transfer with respect to any Escrow Shares until both the Lock-Up Period has expired and such Escrow Shares have been disbursed to Holder from the Escrow Account in accordance with the terms and conditions of the Merger Agreement and the Escrow Agreement.

(c)If any Prohibited Transfer is made or attempted contrary to the provisions of this Agreement, such purported Prohibited Transfer shall be null and void ab initio, and Purchaser shall refuse to recognize any such purported transferee of the Restricted Securities as one of its equity holders for any purpose. In order to enforce this Section 1, Purchaser may impose stop-transfer instructions with respect to the Restricted Securities of Holder (and Permitted Transferees and assigns thereof) until the end of the Lock-Up Period.

2 

(d) During the Lock-Up Period (and with respect to any Escrow Shares, if longer, during the period when such Escrow Shares are held in the Escrow Account), each certificate evidencing any Restricted Securities shall be stamped or otherwise imprinted with a legend in substantially the following form, in addition to any other applicable legends:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF [●], 2020, BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “ISSUER”), A CERTAIN REPRESENTATIVE OF THE ISSUER NAMED THEREIN AND THE ISSUER’S SECURITY HOLDER NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

(e)For the avoidance of any doubt, Holder shall retain all of its rights as a stockholder of the Purchaser during the Lock-Up Period, including the right to vote any Restricted Securities, subject to the terms of the Merger Agreement and the Escrow Agreement with respect to Escrow Shares.

(f)Promptly upon the expiration of the Lock-up Period (and with respect to any Escrow Shares, if released to Holder after the expiration of the Lock-Up Period, promptly upon release from the Escrow Account), the Purchaser agrees to take all commercially reasonable steps necessary to promptly effect the removal of the legend described in Section 1(d) above, and reissue to Holder, at the Purchaser’s sole expense, a new certificate without the legend.

2.Miscellaneous.

(a)Termination of Merger Agreement. This Agreement shall be binding upon Holder upon Holder’s execution and delivery of this Agreement, but this Agreement shall only become effective upon the Closing. Notwithstanding anything to the contrary contained herein, in the event that the Merger Agreement is terminated in accordance with its terms prior to the Closing, this Agreement and all rights and obligations of the parties hereunder shall automatically terminate and be of no further force or effect.

(b)Binding Effect; Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. This Agreement and all obligations of Holder are personal to Holder and may not be transferred or delegated by Holder at any time. The Purchaser may freely assign any or all of its rights under this Agreement, in whole or in part, to any successor entity (whether by merger, consolidation, equity sale, asset sale or otherwise) without obtaining the consent or approval of Holder. If the Purchaser Representative is replaced in accordance with the terms of the Merger Agreement, the replacement Purchaser Representative shall automatically become a party to this Agreement as if it were the original Purchaser Representative hereunder.

Each party agrees that a final judgment in any Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

(h)Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of the Purchaser, the Purchaser Representative and Holder. No failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision.

5 

(i)Severability. In case any provision in this Agreement shall be held invalid, illegal or unenforceable in a jurisdiction, such provision shall be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the same valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby nor shall the validity, legality or enforceability of such provision be affected thereby in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties will substitute for any invalid, illegal or unenforceable provision a suitable and equitable provision that carries out, so far as may be valid, legal and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

(j)Specific Performance. Each party acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in the event of a breach of this Agreement by such party, money damages will be inadequate and the other parties will have no adequate remedy at law, and agrees that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by such party in accordance with their specific terms or were otherwise breached. Accordingly, each party shall be entitled to an injunction or restraining order to prevent breaches of this Agreement by the other parties and to enforce specifically the terms and provisions hereof, without the requirement to post any bond or other security or to prove that money damages would be inadequate, this being in addition to any other right or remedy to which such party may be entitled under this Agreement, at law or in equity.

(k)Entire Agreement. This Agreement constitutes the full and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled; provided, that, for the avoidance of doubt, the foregoing shall not affect the rights and obligations of the parties under the Merger Agreement or any Ancillary Document. Notwithstanding the foregoing, nothing in this Agreement shall limit any of the rights or remedies of the Purchaser and the Purchaser Representative or any of the obligations of Holder under any other agreement between Holder and the Purchaser or the Purchaser Representative or any certificate or instrument executed by Holder in favor of the Purchaser or the Purchaser Representative, and nothing in any other agreement, certificate or instrument shall limit any of the rights or remedies of the Purchaser or the Purchaser Representative or any of the obligations of Holder under this Agreement.

(l)Further Assurances. From time to time, at another party’s request and without further consideration (but at the requesting party’s reasonable cost and expense), each party shall execute and deliver such additional documents and take all such further action as may be reasonably necessary to consummate the transactions contemplated by this Agreement.

(m)Counterparts; Facsimile.  This Agreement may also be executed and delivered by facsimile signature or by email in portable document format in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
