permitted prior thereto. PubCo shall maintain in full force and effect directors’ and officers’ liability insurance in reasonable amounts from established and reputable insurers. In all directors’ and officers’ insurance
policies, each Director designated by a Sponsor Investor shall be covered as an insured in such a manner as to provide each such Director with rights and benefits under such insurance policies no less favorable than those provided to the other

Investor Party to any of such Investor Party’s Permitted Transferees in accordance with Section 3.1(c).

or indirect parents of any such general partners, managers and managing members), as applicable, of funds, investment vehicle or similar entity affiliated with, advised or managed by the
Starboard Sponsor; (ii) in the case of an individual, by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or an Affiliate of such individual,
or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent and distribution upon death of such individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order;

(i) through (vii), collectively, “Permitted Transferees”); provided, however, that, as a condition to any Transfer to a Permitted Transferee pursuant to this Section 3.1(c), such
Permitted Transferee shall execute a joinder to this Stockholders Agreement, substantially in the form attached hereto as Exhibit A (the “Joinder”), agreeing to be bound by all of the terms, provisions and
conditions of this Stockholders Agreement that apply to a Permitted Transferee (including the Transfer restrictions set forth in this Article III).

(c) Nothing in this Stockholders Agreement, express or implied, is intended to confer upon any Party, other than the Parties
and their respective successors and Permitted Transferees, any rights or remedies under this Stockholders Agreement or otherwise create any third party beneficiary hereto. 

Section 4.2 Termination. This Stockholders Agreement shall terminate automatically (without any action by any Party) as to Seller,

Stockholders Agreement and (b) is no longer subject to the applicable restrictions on transfer described in Article III; provided that Section 2.1(n), Section 2.2 and

 Section 4.4 Entire Agreement; Amendments; No Waiver. 

(a) This Stockholders Agreement, together with any Exhibits to this Stockholders Agreement, the Registration Rights Agreement,
the Merger Agreement and all other Transaction Agreements, constitute the entire agreement among the Parties with respect to the subject matter hereof and thereof and supersede all prior and contemporaneous agreements, understandings and
discussions, whether oral or written, relating to such subject matter in any way and there are no warranties, representations or other agreements among the Parties in connection with such subject matter except as set forth in this Stockholders
Agreement and therein. 
 (b) No provision of this Stockholders Agreement may be amended or modified in whole or in part at
any time without the express written consent of (i) PubCo, (ii) Seller, (iii) the BC Stockholder Parties, (iv) the Medina Stockholder Parties and (v) the Starboard Sponsor; provided that a provision that has terminated
with respect to a Party shall not require any consent of such Party with respect to amending or modifying such provision. 

(c) No waiver of any provision or default under, nor consent to any exception to, the terms of this Stockholders Agreement
shall be effective unless in writing and signed by the Party to be bound and then only to the specific purpose, extent and instance so provided.

documents delivered pursuant to this Stockholders Agreement may be executed and delivered in one or more counterparts and by fax, email or other electronic transmission, each of which shall be deemed an original and all of which shall be considered
one and the same agreement. No Party shall raise the use of a fax machine or email to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a fax machine or email as a
defense to the formation or enforceability of a contract and each Party forever waives any such defense. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to
this Stockholders Agreement or any document to be signed in connection with this Stockholders Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same
legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the Parties consent to conduct the transactions contemplated hereunder by
electronic means.

 Section 4.7 Governing Law; Waiver of Jury Trial; Jurisdiction. 

(a) The Law of the State of Delaware shall govern (i) all Actions, claims or matters related to or arising from this
Stockholders Agreement and the negotiation, entering into and performance of this Stockholders Agreement (including any tort or non-contractual claims) and (ii) any questions concerning the construction,
interpretation, validity and enforceability of this Stockholders Agreement, and the performance of the obligations imposed by this Stockholders Agreement, in each case without giving effect to any choice of law or conflict of law rules or provisions
(whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any jurisdiction other than the State of Delaware. 

(b) EACH PARTY TO THIS STOCKHOLDERS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION BROUGHT TO
RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES (WHETHER ARISING IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS STOCKHOLDERS AGREEMENT, THE TRANSACTIONS CONTEMPLATED BY THIS STOCKHOLDERS
AGREEMENT OR THE RELATIONSHIPS ESTABLISHED AMONG THE PARTIES UNDER THIS STOCKHOLDERS AGREEMENT. THE PARTIES FURTHER WARRANT AND REPRESENT THAT EACH HAS REVIEWED THIS WAIVER WITH SUCH PARTY’S LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND
VOLUNTARILY WAIVES SUCH PARTY’S JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. 
 (c) Each of the Parties
submits to the exclusive jurisdiction of first, the Chancery Court of the State of Delaware, or if such court declines jurisdiction, then to the Federal District Court for the District of Delaware, in any Action arising out of or relating to this
Stockholders Agreement, agrees that all claims in respect of the Action shall be heard and determined in any such court and agrees not to bring any Action arising out of or relating to this Stockholders Agreement in any other courts. Each Party
irrevocably consents to the service of process in any such Action by the mailing of copies thereof by registered or certified mail, postage prepaid, to such Party, at its address for notices as provided in Section 4.6, such
service to become effective ten (10) days after such mailing. Each Party hereby irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any Action commenced hereunder or
under any other documents contemplated hereby that service of process was in any way invalid or ineffective. Nothing in this Section 4.7, however, shall affect the right of any Party to serve legal process in any other
manner permitted by Law or at equity; provided that each of the Parties hereby waives any right it may have under the Laws of any jurisdiction to commence by publication any Action with respect to this Stockholders Agreement. To the fullest
extent permitted by applicable Law, each of the Parties hereby irrevocably waives any objection it may now or hereafter have to the laying of venue of any Action arising out of or relating to this Stockholders Agreement in any of the courts referred
to in this Section 4.7 and hereby further irrevocably waives and agrees not to plead or claim that any such court is not a convenient forum for any such Action. Each Party agrees that a final judgment in any Action so
brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law or at equity, in any jurisdiction. 

Section 4.8 Specific Performance. Each Party hereby agrees and acknowledges that it will be impossible to measure in money the
damages that would be suffered if the Parties fail to comply with any of the obligations imposed on them by this Stockholders Agreement and that, in the event of any such failure, an aggrieved Party will be irreparably damaged and will not have an
adequate remedy at Law. Any such Party shall, therefore, be entitled (in addition to any other remedy to which such Party may be entitled at Law or in equity) to seek injunctive relief, including specific performance, to enforce such obligations,
without the posting of any bond, and if any Action should be brought in equity to enforce any of the provisions of this Stockholders Agreement, none of the Parties shall raise the defense that there is an adequate remedy at Law. 

Section 4.9 Representations and Warranties of the Parties. 

(a) Each of the Parties hereby represents and warrants to each of the other Parties as follows: 

  
 13 













 (i) Such Party, to the extent applicable, is duly organized, formed or
incorporated, validly existing and in good standing under the Laws of the jurisdiction of its organization, formation or incorporation and has all requisite power and authority to conduct its business as it is now being conducted and is proposed to
be conducted. 
 (ii) Such Party has the full power, authority and legal right to execute, deliver and perform this
Stockholders Agreement. The execution, delivery and performance of this Stockholders Agreement have been duly authorized by all necessary action, corporate or otherwise, of such Party. This Stockholders Agreement has been duly executed and delivered
by such Party and constitutes its, his or her legal, valid and binding obligation, enforceable against it, him or her in accordance with its terms, subject to applicable bankruptcy, insolvency and similar Laws affecting creditors’ rights
generally. 
 (iii) The execution and delivery by such Party of this Stockholders Agreement, the performance by such Party of
its, his or her obligations hereunder by such Party does not and will not violate (a) in the case of Parties who are not individuals, any provision of its by-laws, charter, articles of association,
partnership agreement or other similar organizational document, (b) any provision of any material agreement to which it, he or she is a Party or by which it, he or she is bound or (c) any law, rule, regulation, judgment, order or decree to
which it, he or she is subject. 
 (iv) Such Party is not currently in violation of any law, rule, regulation, judgment,
order or decree, which violation could reasonably be expected at any time to have a material adverse effect upon such Party’s ability to enter into this Stockholders Agreement or to perform its, his or her obligations hereunder. 

(v) There is no pending legal action, suit or proceeding that would materially and adversely affect the ability of such Party
to enter into this Stockholders Agreement or to perform its, his or her obligations hereunder. 
 Section 4.10 No Third Party
Liabilities. This Stockholders Agreement may only be enforced against the named Parties (and their Permitted Transferees who become parties to this Stockholders Agreement by virtue of executing the Joinder). All claims or causes of action
(whether in contract or tort) that may be based upon, arise out of or relate to any of this Stockholders Agreement, or the negotiation, execution or performance of this Stockholders Agreement (including any representation or warranty made in or in
connection with this Stockholders Agreement or as an inducement to enter into this Stockholders Agreement), may be made only against the Persons that are expressly identified as Parties (and their Permitted Transferees), as applicable; and, other
than for any Permitted Transferee, no past, present or future direct or indirect director, officer, employee, incorporator, member, partner, stockholder, Affiliate, portfolio company in which any such Party or any of its investment fund Affiliates
have made a debt or equity investment (and vice versa), agent, attorney or representative of any Party (including any Person negotiating or executing this Stockholders Agreement on behalf of a Party), unless a Party to this Stockholders Agreement,
shall have any liability or obligation with respect to this Stockholders Agreement or with respect any claim or cause of action (whether in contract or tort) that may arise out of or relate to this Stockholders Agreement, or the negotiation,
execution or performance of this Stockholders Agreement (including a representation or warranty made in or in connection with this Stockholders Agreement or as an inducement to enter into this Stockholders Agreement). 

Section 4.11 Adjustments. If there are any changes in Common Stock as a result of stock split, stock dividend, combination or
reclassification, or through merger, consolidation, recapitalization or other similar event, appropriate adjustment shall be deemed to have been made in the provisions of this Stockholders Agreement, as may be appropriate, so that the rights,
privileges, duties and obligations under this Stockholders Agreement shall continue with respect to Common Stock as so changed. 

Section 4.12 Certain Tax Matters. PubCo shall reasonably cooperate with each of the BC Stockholder and Starboard Sponsor with
regard to, and use commercially reasonable efforts to provide each of the BC Stockholder and Starboard Sponsor, as applicable, upon written request and provided that the BC Stockholder or Starboard Sponsor, as applicable, will (subject to the terms
of the rest of this Section 4.12) reimburse reasonable out of pocket third party costs and expenses specifically related to fulfilling such request, with all requested information, records, and documents related to PubCo
and its subsidiaries, to the extent such information is reasonable, does not create any 

  
 14 













 
fiduciary or regulatory issues and is reasonably available to PubCo, that are reasonably necessary for, (a) the completion of tax and information returns of the BC Stockholder and its
Affiliates (or their direct or indirect equity owners) and their compliance with any applicable tax laws, including with respect to withholding tax obligations, (b) the preparation for and defense of any audits or other disputes with any taxing
authority regarding any taxes or tax returns to the extent related to the investment by the BC Stockholder in PubCo, (c) responding to any inquiry from any Governmental Authority regarding taxes, or obtaining refunds of, or exemptions from any,
withholding taxes imposed on the BC Stockholder (or its direct or indirect equity owners) as a result of its investment in PubCo; provided, however, that BC Stockholder shall execute a customary confidentiality agreement in advance of
receiving any information, records or documents from PubCo; provided, further, that PubCo may withhold any information, records or documents from BC Stockholder if access to such information, records or documents could adversely affect the
attorney-client privilege between PubCo and its counsel or result in disclosure of trade secrets, competitively sensitive information or a conflict of interest, a breach of any fiduciary duties or create any regulatory issues, or BC Stockholder is
reasonably determined to be a competitor of PubCo or if PubCo otherwise reasonably determines that doing so would be inconsistent with PubCo’s legal or regulatory obligations (the limitations on disclosure described in this proviso, the
“Disclosure Limitations”). Without limiting the generality of the foregoing, (x) in the event that PubCo makes any actual or deemed distribution to its stockholders, PubCo shall use commercially reasonable efforts to provide to
the BC Stockholder, upon written request and as soon as practicable following such request, such information regarding the current and accumulated “earnings and profits” of PubCo (including any projections with respect to current earnings
and profits) as the BC Stockholder or Starboard Sponsor, as applicable, may reasonably request, to the extent such information is reasonably available to PubCo and (y) PubCo shall (1) provide to the BC Stockholder or Starboard Sponsor, as
applicable, upon a written request and as soon as practicable following such request (and provided that PubCo shall use its commercially reasonable efforts to reply to any such request within fourteen (14) days following such request, and shall
reply in any event no later than thirty (30) days following such request), either (A) a certification that PubCo is not a United States real property holding company (a “USRPHC”), in accordance with Treasury Regulations
Sections 1.897-2(g)(1)(ii) and 1.897-2(h)(1) or (B) written notice of its legal inability to provide such a certification due to its status as a USRPHC, and
(2) in connection with the provision of any certification pursuant to the preceding clause (1)(A), comply with the notice provisions set forth in Treasury Regulations Section 1.897-2(h)(2).
Notwithstanding anything else contained herein, in no event will the BC Stockholder or Starboard Sponsor have any obligation to reimburse PubCo for (i) the regular and ordinary costs (including the costs of maintaining the “earnings and
profits”) of PubCo that are incurred in the normal course of business or (ii) for so long as Common Stock Beneficially Owned, directly or indirectly, by the BC Stockholder Parties (in the aggregate) or the Starboard Sponsor, as applicable,
is equal to or greater than five percent (5%) of PubCo’s outstanding Common Stock, for any other costs that are incurred with respect to providing (or providing notice that it is not legally entitled to provide) the certification described in
the immediately preceding clause (y). 
 Notwithstanding the forgoing, in no event will the obligations undertaken by PubCo pursuant to this
Section 4.12 create any obligation of PubCo to indemnify or reimburse the BC Stockholder, Starboard Sponsor or any of their respective Affiliates (or their direct or indirect equity owners) for any taxes (including any
interest, penalties, and/or expenses) incurred by or imposed on, the BC Stockholder and its Affiliates (or their direct or indirect equity owners) or Starboard Sponsor and its Affiliates (or their direct or indirect equity owners). 

Section 4.13 Further Assurances. Without limiting anything contained elsewhere in this Stockholders Agreement, at any time or from
time to time after the date hereof, the Parties agree to cooperate with each other, and at the request of any other Party, to execute and deliver any further instruments or documents and to take all such further action as any other Party may
reasonably request in order to evidence or effectuate the provisions of this Stockholders Agreement and to otherwise carry out the intent of the Parties hereunder.
