The Company and the Holders are collectively referred to herein as the “Parties.” Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the APA (as defined below).

BACKGROUND

WHEREAS, in connection with this Agreement, the Company entered into an Asset Purchase Agreement (the “APA”) with the Holder and its wholly owned subsidiary Deer Creek IP, LLC;

WHEREAS, under the terms of the APA, the Company has issued to SRG, as part of the Purchase Price, (a) 800,000 shares of Common Stock and (b) pre-funded Warrants to purchase 739,278 shares of Common Stock (such shares, Warrants and the shares underlying the Warrants being collectively referred to herein as the “Subject Shares”);

WHEREAS, as a condition of, and as a material inducement for, the Company to enter into and consummate the transactions contemplated by the APA, SRG has agreed to execute and deliver this Agreement.

NOW, THEREFORE, for and in consideration of the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties, intending to be legally bound, agree as follows:

AGREEMENT

1. Lock-Up.

(a) Each Holder hereby agrees that it will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any of the Subject Shares, enter into a transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of such Subject Shares, whether any of these transactions are to be settled by delivery of any such Subject Shares, in cash or otherwise, publicly disclose the intention to make any offer, sale, pledge or disposition, or to enter into any transaction, swap, hedge or other arrangement, or engage in any Short Sales (as defined below) with respect to any Subject Shares or any other security of the Company (these actions, collectively, “Transfer”) or interest therein beneficially owned or owned of record by such Holder (collectively, such Holder’s “Lock-Up Shares”) until the date that is six (6) months following the date of the Closing (the “Lock-Up Term”).

(b) Notwithstanding the foregoing restrictions on Transfer set forth herein, each Holder may:

(i) Transfer its Lock-Up Shares to any Permitted Transferee (as defined below);

(ii) Transfer any shares of Common Stock or other securities convertible into or exercisable or exchangeable for Common Stock acquired in open market transactions after the Closing; provided, however, that no such transaction is required to be, or is, publicly announced (whether on Form 4, Form 5 or otherwise, other than a required filing on Schedule 13F, 13D, 13D/A, 13G or 13G/A) during the Lock-Up Term; and

(iii) Exercise any options or warrants (including the Warrant) to purchase shares of Common Stock (which exercises may be effected on a cashless basis to the extent the instruments representing such options or warrants permit exercises on a cashless basis); provided, however, that such Holder shall otherwise comply with any restrictions on Transfer applicable to such underlying shares of Common Stock;

provided, however, that in the case of any Transfer or distribution pursuant to Subsections (b)(i), (x) in each case such transferees must enter into a written agreement agreeing to be bound by this Agreement, including the restrictions on Transfer set forth in Section (a), and (y) such Permitted Transferee (other than a Permitted Transferee as defined in clause (E) or (F) thereof) agrees to promptly Transfer such Lock-Up Shares back to such Holder if such Permitted Transferee ceases to be a Permitted Transferee for any reason prior to the date such Lock-Up Shares becomes freely transferable. Furthermore, Section 1(a) shall not apply to the entry, by such Holder, of any trading plan providing for the sale of shares of Common Stock by such Holder, which trading plan meets the requirements of Rule 10b5-1(c) under the Securities Exchange Act of 1934, as it may be amended from time to time (the “Exchange Act”); provided, however, that such plan does not provide for, or permit, the sale of any Common Stock during the Lock-Up Term and no public announcement or filing is voluntarily made or required regarding such plan during the Lock-Up Term.

(c) Each of the Holders acknowledges and agrees that any purported Transfer of Lock-Up Shares in violation of this Agreement shall be null and void ab initio, and the Company shall not be required to register any such purported Transfer.

(d) Each of the Holders agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the Transfer of the Lock-Up Shares except in compliance with the foregoing restrictions and to the addition of a legend to such Holder’s Lock-Up Shares describing the foregoing restrictions.
