 5 













 (b)    Transfer of the Covered Shares. 

(i)    Before the receipt of the Parent Requisite Vote, the Stockholder hereby agrees not to, directly or
indirectly, (i) sell, transfer, pledge, encumber, assign, hedge, swap, convert, gift-over or otherwise dispose of (including by sale, merger (including by conversion into securities or other consideration), by tendering into any tender or
exchange offer, by testamentary disposition, by liquidation or dissolution, by dividend or distribution, by operation of Law or otherwise), either voluntarily or involuntarily (collectively, “Transfer”), or enter into any Contract,
option or other agreement, arrangement or understanding with respect to the Transfer of any of the Stockholder’s Covered Shares or (ii) take any action that would make any representation or warranty of the Stockholder contained herein

(any such Transfer occurring before the receipt of the Parent Requisite Vote, a “Permitted Transfer”); provided, further, that any Permitted Transfer shall be permitted only if, as a precondition to such Transfer, the
transferee agrees in a writing, reasonably satisfactory in form and substance to the Company, to assume all of the obligations of the Stockholder under, and be bound by all of the terms of, this Agreement. For the avoidance of doubt, nothing in this
Agreement will restrict the Stockholder from Transferring any shares of Parent Common Stock following the conclusion of the Parent Stockholders Meeting duly convened therefor or at any adjournment or postponement thereof, in each case, at which a
vote on the issuance of Parent Common Stock in connection with the Merger was taken, regardless of the outcome of such vote. Any Transfer in violation of this Section 5(b) with respect to the Stockholder’s Covered Shares shall be null and
void and the Stockholder agrees that any such prohibited Transfer may and shall be enjoined.

direct Parent), promptly after the date hereof, to enter, or cause its transfer agent to enter, a stop transfer order with respect to all of the Stockholder’s Covered Shares with respect to any Transfer not permitted hereunder; provided Parent
or its counsel further notifies Parent’s transfer agent to lift and vacate the stop transfer order with respect to the Covered Shares following the conclusion of the Parent Stockholders Meeting duly convened therefor or at any adjournment or
postponement thereof, in each case, at which a vote on the issuance of Parent Common Stock in connection with the Merger was taken, regardless of the outcome of such vote. 

(iii)    In the event that the Stockholder intends to undertake a Permitted Transfer of any of the
Stockholder’s Covered Shares, the Stockholder shall provide notice thereof to the Company and, if the written agreement to be entered into by the transferee agreeing to be bound by this Agreement pursuant to Section 5(b) hereof is
reasonably satisfactory to the Company, shall authorize Parent to, or authorize Parent to instruct its transfer agent to, (i) lift any stop 

  
 6 













 
transfer order in respect of the Stockholder’s Covered Shares to be so Transferred in order to effect such Permitted Transfer and (ii) re-enter
any stop transfer order in respect of the Stockholder’s Covered Shares to be so Transferred upon completion of the Permitted Transfer; provided Parent or its counsel further notifies Parent’s transfer agent to lift and vacate the stop
transfer order with respect to the Covered Shares following the conclusion of the Parent Stockholders Meeting duly convened therefor or at any adjournment or postponement thereof, in each case, at which a vote on the issuance of Parent Common Stock
in connection with the Merger was taken, regardless of the outcome of such vote. 
 (c)    Other
Actions. The Stockholder hereby authorizes Parent to maintain a copy of this Agreement at either the executive office or the registered office of Parent. 

6.    Further Assurances. From time to time, at the Company’s request and without further consideration, the
Stockholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or reasonably requested to effect the actions and consummate the transactions contemplated by this Agreement. The
Stockholder further irrevocably and unconditionally agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against the Company,
Parent or any of their respective successors and assigns relating to the negotiation, execution or delivery of this Agreement, the Merger Agreement or the consummation of the transactions contemplated hereby and thereby, including any action
(i) challenging the validity of, or seeking to enjoin the operation of, any provision of the Merger Agreement or this Agreement or (ii) alleging breach of any fiduciary duty of any Person in connection with the negotiation and entry into
the Merger Agreement, this Agreement or the transactions contemplated hereby or thereby. 
 7.    Public
Announcements; Disclosure. The Stockholder shall not, and shall cause its Representatives not to, directly or indirectly, make any press release, public announcement or other public communication in respect of this Agreement or the Merger
Agreement or any of the transactions contemplated hereby and thereby without the prior written consent of the Company, except as required by applicable federal securities Laws; provided, that the foregoing limitations shall not apply
following any Parent Change of Recommendation. The Stockholder hereby (i) authorizes Parent and the Company to publish and disclose in any announcement or disclosure required by the SEC (including in the Joint Proxy Statement and the
Registration Statement) the Stockholder’s identity and ownership of the Covered Shares, the nature of the Stockholder’s obligations under this Agreement and any other information that Parent or the Company determines to be necessary in any
SEC disclosure document and (ii) agrees as promptly as practicable to notify Parent and the Company of any required corrections with respect to any written information supplied by the Stockholder specifically for use in any such disclosure
document. 
 8.    Changes in Capital Stock. In the event of a stock split, stock dividend or distribution, or
any change in Parent’s capital stock by reason of any split-up, reverse stock split, recapitalization, combination, reclassification, exchange of shares or the like between the date of this Agreement and
the Effective Time, the terms “Owned Shares” and “Covered Shares” shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which or for which any or all of

10.    Waiver. No failure or delay by any party hereto exercising any right, power or privilege hereunder shall
operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the parties hereto hereunder are
cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder. Any agreement on the part of a party hereto to any such waiver shall be valid only if set forth in a written instrument executed and delivered by

13.    Entire Agreement. This Agreement constitutes the entire agreement and supersede all prior agreements and
understandings, both written and oral, between the parties hereto with respect to the subject matter hereof and thereof. Each of the parties hereto hereby acknowledges and agrees, on behalf of itself, its Affiliates and each of their respective

herein, and the parties hereto hereby further agree that this Agreement may only be enforced against, and any Action that may be based upon, arise out of or relate to this Agreement, or the
negotiation, execution or performance of this Agreement may only be made against, the Persons expressly named as parties hereto; provided, however, that Parent shall be a third-party beneficiary of Section 7
of this Agreement. 
 15.    Governing Law and Venue; Service of Process; Waiver of Jury Trial. 

(a)    This Agreement and any disputes relating hereto shall be governed by, and construed in accordance
with, the laws of the State of Delaware (without giving effect to choice of law or conflict of law principles thereof or of any other jurisdiction that would cause the application of any laws of any jurisdiction other than the State of Delaware).

 (b)    Each of the parties hereto irrevocably (i) consents to submit itself to the personal
jurisdiction of the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (unless the Delaware Court of Chancery shall decline to accept jurisdiction over a particular matter, in which case, in any Delaware
state or federal court within the State of Delaware), in connection with any matter based upon or arising out of this Agreement or any of the transactions contemplated by this Agreement or the actions of the Company or the Stockholder in the
negotiation, administration, performance and enforcement hereof and thereof, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (iii) agrees that it
will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the courts of the State of Delaware, as described above, and (iv) consents to service being made through the
notice procedures set forth in Section 11. Each party hereto agrees that service of any process, summons, notice or document by U.S. registered mail to the respective addresses set forth in Section 11 shall be effective service of process
for any suit or proceeding in connection with this Agreement or the transactions contemplated hereby. Each party hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or
proceeding with respect to this Agreement, any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to serve process in accordance with this Section 15(b), that it or its
property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment
or otherwise), and to the fullest extent permitted by applicable Law, that the suit, action or proceeding in any such court is brought in an inconvenient forum, that the venue of such suit, action or proceeding is improper, or that this Agreement,
or the subject matter hereof or thereof, may not be enforced in or by such courts and further irrevocably waives, to the fullest extent permitted by applicable Law, the benefit of any defense that would hinder, fetter or delay the levy, execution or
collection of any amount to which the party is entitled pursuant to the final judgment of any court having jurisdiction. Each party expressly acknowledges that the foregoing waiver is intended to be irrevocable under the Laws of the State of
Delaware and of the United States of America; provided that each such party’s consent to jurisdiction and service contained in this Section 15(b) is solely for the purpose referred to in this Section 15(b) and shall not be
deemed to be a general submission to said courts or in the State of Delaware other than for such purpose. 

  
 10 













 (c)    EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ANY
AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE COMPANY OR THE
STOCKHOLDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF OR THEREOF. 
 16.    Assignment;
Successors. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto in whole or in part (whether by operation of Law or otherwise) without the prior written consent of the
other party, and any such assignment without such consent shall be null and void. This Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns. 

17.    Enforcement. The parties hereto agree that irreparable damage for which monetary damages, even if available,
may not be an adequate remedy, would occur in the event that the parties hereto do not perform the provisions of this Agreement (including the Stockholder’s obligations to vote its Covered Shares as provided in this Agreement) in accordance
with its specified terms or otherwise breach such provisions. The parties hereto acknowledge and agree that the parties hereto shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement
and to enforce specifically the terms and provisions hereof, without any requirement for the posting of security, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereto agrees that it
will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that (x) either party has an adequate remedy at law or (y) an award of specific performance is not an
appropriate remedy for any reason at law or equity. 
 18.    Severability. If any term or other provision of
this Agreement is found by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and
effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are
fulfilled to the fullest extent possible. 
 19.    Counterparts. This Agreement may be executed and delivered
(including by email transmission, “.pdf,” or other electronic 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.

 20.    Interpretation and Construction. When reference is made in
this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to
be followed by the words “without limitation.” The words “hereof,” “herein,” “hereby” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole
and not to any particular provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant thereto unless otherwise defined therein. Words of
any gender include each other gender and neuter genders and words using the singular or plural number also include the plural or singular number, respectively. Any Contract or Law defined or referred to herein means such Contract or Law as from time
to time amended, modified or supplemented, including (in the case of Contracts) by waiver or consent and (in the case of Laws) by succession or comparable successor statutes and references to all attachments thereto and instruments incorporated
therein. The word “or” shall not be exclusive. The word “will” shall be construed to have the same meaning as the word “shall”. Whenever this Agreement refers to a number of days, such number shall refer to calendar
days unless Business Days are specified. The word “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”. Any deadline or time period set forth in this
Agreement that by its terms ends on a day that is not a Business Day shall be automatically extended to the next succeeding Business Day. Each of the parties hereto has participated in the drafting and negotiating of this Agreement. If an ambiguity
or question of intent or interpretation arises, this Agreement shall be construed as if it is drafted by all the parties hereto and without regard to any presumption or rule requiring construction or interpretation against the party drafting or
causing any instrument to be drafted. 
 21.    Capacity as a Stockholder. Notwithstanding anything herein to the
contrary, the Stockholder signs this Agreement solely in the Stockholder’s capacity as a stockholder of Parent, and not in any other capacity and this Agreement shall not limit or otherwise affect the actions (including the exercise of
fiduciary duties) in accordance with applicable Law of any Affiliate, employee or designee of the Stockholder or any of its Affiliates in his or her capacity, if applicable, as an officer or director of Parent or any other Person. 

22.    Expenses. All fees and expenses incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated.
