and Warranties of the Company 
 The Company represents and warrants to the Investor as of the date hereof and as of the Closing (except
to the extent made only as of a specified date, in which case such representation and warranty is made as of such date) that, except as (A) set forth in the confidential disclosure letter delivered by the Company to the Investor prior to the
execution of this Agreement (the “Company Disclosure Letter”) (it being understood that any information, item or matter set forth on one section or subsection of the Company Disclosure Letter shall only be deemed disclosure with
respect to, and shall only be deemed to apply to and qualify, the section or subsection of this Agreement to which it corresponds in number and each other section or subsection of this Agreement to the extent that it is reasonably apparent that such
information, item or matter is relevant to such other section or subsection) or (B) disclosed in any report, schedule, form, statement or other document (including exhibits) filed with, or furnished to, the SEC and publicly available after
December 31, 2017 and prior to the date hereof (the “Filed SEC Documents”), other than any risk factor disclosures in any such Filed SEC Document contained in the “Risk Factors” section or any forward-looking
statements within the meaning of the Securities Act or the Exchange Act thereof (other than statements of historical fact) (it being acknowledged that nothing disclosed in the Filed SEC Documents shall be deemed to qualify or modify the
representations and warranties set forth in Sections 3.02(a), 3.03, 3.10 and 3.11): 

  
 10 

 Section 3.01 Organization; Standing. (a) The Company is
validly existing as a corporation under the Laws of the State of Texas and listed as “active” on the franchise tax records of the Comptroller of Public Accounts of the State of Texas and has all requisite corporate power and corporate
authority necessary to carry on its business as it is now being conducted, except (other than with respect to the Company’s due organization and valid existence) as would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. The Company is duly licensed or qualified to do business and is in good standing (where such concept is recognized under applicable Law) in each jurisdiction in which the nature of the business conducted by it or the
character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed, qualified or in good standing would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect. True and complete copies of the Company Charter Documents are included in the Filed SEC Documents. 

(b) Each of the Company’s Subsidiaries is duly organized, validly existing and in good standing (where such concept is recognized under
applicable Law) under the Laws of the jurisdiction of its organization, except where the failure to be so organized, existing and in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

 Section 3.02 Capitalization. (a) The authorized capital stock of the Company consists of 175,000,000 shares of
Common Stock, par value $0.01, and 10,000,000 shares of preferred stock, par value $1.00 (“Company Preferred Stock”), of which 64,914 shares of Series A Preferred Stock and 35,086 shares of Series B Preferred Stock will be
authorized as of the Closing. At the close of business on December 31, 2018 (the “Capitalization Date”), (i) 54,186,180 shares of Common Stock were issued and outstanding, (ii) 5,967,486 shares of Common Stock were reserved and
available for issuance pursuant to the Company Stock Plans, (iii) 923,823 shares of Common Stock were subject to outstanding Company Stock Options, (iv) 1,367,499 Company RSUs were outstanding pursuant to which a maximum of 1,367,499 shares of
Common Stock could be issued and (v) no shares of Company Preferred Stock were issued or outstanding. 
 (b) Except as described in this
Section 3.02, as of the Capitalization Date, there were (i) no outstanding shares of capital stock of, or other equity or voting interests in, the Company, (ii) no outstanding securities of the Company convertible
into or exchangeable for shares of capital stock of, or other equity or voting interests in, the Company, (iii) no outstanding options, warrants, rights or other commitments or agreements to acquire from the Company, or that obligate the
Company to issue, any capital stock of, or other equity or voting interests (or voting debt) in, or any securities convertible into or exchangeable for shares of capital stock of, or other equity or voting interests in, the Company other than
obligations under the Company Plans in the ordinary course of business, (iv) no obligations of the Company to grant, extend or enter into any subscription, warrant, right, convertible or exchangeable security or other similar agreement or
commitment relating to any capital stock of, or other equity or voting interests in, the Company (the items in clauses (i), (ii), (iii) and (iv) being referred to collectively as “Company Securities”) and (v) no other
obligations by the Company or any of its Subsidiaries to make any payments based on the price or value of any Company Securities. There are no outstanding agreements of any kind which obligate the Company or any of its Subsidiaries to

  
 11 

 
repurchase, redeem or otherwise acquire any Company Securities (other than pursuant to the cashless exercise of Company Stock Options or the forfeiture or withholding of Taxes with respect to
Company Stock Options or Company RSUs), or obligate the Company to grant, extend or enter into any such agreements relating to any Company Securities, including any agreements granting any preemptive rights, subscription rights, anti-dilutive
rights, rights of first refusal or similar rights with respect to any Company Securities. None of the Company or any Subsidiary of the Company is a party to any stockholders’ agreement, voting trust agreement, registration rights agreement or
other similar agreement or understanding relating to any Company Securities or any other agreement relating to the disposition, voting or dividends with respect to any Company Securities. All outstanding shares of Common Stock have been duly
authorized and validly issued and are fully paid, nonassessable and free of preemptive rights. 
 Section 3.03 Authority;
Noncontravention. (a) The Company has all necessary corporate power and corporate authority to execute and deliver this Agreement and the other Transaction Documents and to perform its obligations hereunder and thereunder and to
consummate the Transactions. The execution, delivery and performance by the Company of this Agreement and the other Transaction Documents, and the consummation by it of the Transactions, have been duly authorized by the Board and no other corporate
action on the part of the Company is necessary to authorize the execution, delivery and performance by the Company of this Agreement and the other Transaction Documents and the consummation by it of the Transactions. This Agreement has been duly
executed and delivered by the Company and, assuming due authorization, execution and delivery hereof by the Investor, constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms,
except that such enforceability (i) may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar Laws of general application affecting or relating to the enforcement of creditors’ rights
generally and (ii) is subject to general principles of equity, whether considered in a proceeding at law or in equity (the “Bankruptcy and Equity Exception”). Pursuant to resolutions in form and substance previously reviewed by
the Investor, the Board or a committee thereof composed solely of two or more “non-employee directors” as defined in Rule 16b-3 of the Exchange Act has
approved, for the express purpose of exempting each such transaction from Section 16(b) of the Exchange Act, pursuant to Rule 16b-3 thereunder to the extent applicable, the transactions contemplated by
the Transaction Documents, including the acquisition of the Preferred Stock, any disposition of such stock upon the conversion thereof, any acquisition of Common Stock or Series A Preferred Stock upon conversion of the Series A Preferred Stock or
Series B Preferred Stock, as applicable, any deemed acquisition or disposition in connection therewith, and all transactions with the Company related thereto. 

(b) Neither the execution and delivery of this Agreement or the other Transaction Documents by the Company, nor the consummation by the Company
of the Transactions, nor performance or compliance by the Company with any of the terms or provisions hereof or thereof, will (i) conflict with or violate any provision of (A) the Company Charter Documents or (B) the similar
organizational documents of any of the Company’s Subsidiaries or (ii) assuming that the authorizations, consents and approvals referred to in Section 3.04 are obtained prior to the Closing Date and the filings
referred to in Section 3.04 are made and any waiting periods thereunder have terminated or expired prior to the Closing Date, (x) violate any Law or Judgment applicable to the Company or any of its Subsidiaries or

  
 12 

 
(y) violate or constitute a default (or constitute an event which, with notice or lapse of time or both, would violate or constitute a default) under any of the terms or provisions of any
loan or credit agreement, indenture, debenture, note, bond, mortgage, deed of trust, lease, sublease, license, contract or other agreement (each, a “Contract”) to which the Company or any of its Subsidiaries is a party or accelerate
the Company’s or, if applicable, any of its Subsidiaries’ obligations under any such Contract, except, in the case of clause (i)(B) and clause (ii), as would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. 
 Section 3.04 Governmental Approvals. Except for (a) the filing of the Certificates of
Designations with the Secretary of State of the State of Texas, (b) filings required under, and compliance with other applicable requirements of the HSR Act and (c) compliance with any applicable state securities or blue sky laws, no
consent or approval of, or filing, license, permit or authorization, declaration or registration with, any Governmental Authority is necessary for the execution and delivery of this Agreement and the other Transaction Documents by the Company, the
performance by the Company of its obligations hereunder and thereunder and the consummation by the Company of the Transactions, other than such other consents, approvals, filings, licenses, permits or authorizations, declarations or registrations
that, if not obtained, made or given, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

Section 3.05 Company SEC Documents; Undisclosed Liabilities. (a) The Company has filed with the SEC, on a timely basis, all required
reports, schedules, forms, statements and other documents required to be filed by the Company with the SEC pursuant to the Exchange Act since January 1, 2017 (collectively, the “Company SEC Documents”). As of their respective
SEC filing dates, the Company SEC Documents complied as to form in all material respects with the requirements of the Securities Act, the Exchange Act or the Sarbanes-Oxley Act of 2002 (and the regulations promulgated thereunder), as the case may
be, applicable to such Company SEC Documents, and none of the Company SEC Documents as of such respective dates (or, if amended prior to the date hereof, the date of the filing of such amendment, with respect to the disclosures that are amended)
contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. 

(b) The consolidated financial statements of the Company (including all related notes or schedules) included or incorporated by reference in
the Company SEC Documents complied as to form, as of their respective dates of filing with the SEC, in all material respects with the published rules and regulations of the SEC with respect thereto, have been prepared in all material respects in
accordance with GAAP (except, in the case of unaudited quarterly statements, as permitted by Form 10-Q of the SEC or other rules and regulations of the SEC) applied on a consistent basis during the periods
involved (except (i) as may be indicated in the notes thereto or (ii) as permitted by Regulation S-X) and present fairly, in all material respects, the consolidated financial position of the
Company as of the dates thereof and the consolidated results of its operations and its cash flows for the periods shown (subject, in the case of unaudited quarterly financial statements, to normal year-end
adjustments). 

  
 13 

 (c) Neither the Company nor any of its Subsidiaries has any liabilities of any nature
(whether accrued, absolute, contingent or otherwise) that would be required under GAAP, as in effect on the date hereof, to be reflected on a consolidated balance sheet of the Company (including the notes thereto) except liabilities
(i) reflected or reserved against in the balance sheet (or the notes thereto) of the Company and its Subsidiaries as of September 30, 2018 (the “Balance Sheet Date”) included in the Filed SEC Documents, (ii) incurred
after the Balance Sheet Date in the ordinary course of business, (iii) as expressly contemplated by this Agreement or otherwise incurred in connection with the Transactions, the Acquisition or the Debt Financing, (iv) that have been
discharged or paid prior to the date of this Agreement or (v) as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

(d) The Company has established and maintains, and at all times since January 1, 2017 has maintained, disclosure controls and procedures
and a system of internal controls over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act. Neither the Company nor, to the Company’s Knowledge, the Company’s independent registered public accounting firm, has identified or been made aware of “significant
deficiencies” or “material weaknesses” (as defined by the Public Company Accounting Oversight Board) in the design or operation of the Company’s internal controls over and procedures relating to financial reporting which would
reasonably be expected to adversely affect in any material respect the Company’s ability to record, process, summarize and report financial data, in each case which has not been subsequently remediated. 

Section 3.06 Absence of Certain Changes. Since January 1, 2018 through the date of this Agreement
(a) except for the execution and performance of this Agreement, the Acquisition Agreement and the Debt Commitment Letter and any other agreements contemplated thereby and the discussions, negotiations and transactions related thereto, the
business of the Company and its Subsidiaries has been carried on and conducted in all material respects in the ordinary course of business and (b) there has not been any Material Adverse Effect or any event, change or occurrence that would,
individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Since September 30, 2018 through the date of this Agreement, the Company has not taken any actions which, had such actions been taken after the date of
this Agreement, would have required the written consent of the Investor Parties pursuant to Section 5.01. 

Section 3.07 Legal Proceedings. Except as would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect, to the Knowledge of the Company, as of the date of this Agreement, there is no (a) pending or threatened legal or administrative proceeding, suit, investigation, arbitration or action (an “Action”)
against the Company or any of its Subsidiaries or (b) outstanding order, judgment, injunction, ruling, writ or decree of any Governmental Authority (“Judgments”) imposed upon the Company or any of its Subsidiaries, in each
case, by or before any Governmental Authority.

law, statutes, ordinances, codes, rules or regulations or other similar requirement enacted, adopted, promulgated, or applied by any Governmental Authority (“Laws”) or Judgments, in each case, that are applicable to the Company or
any of its Subsidiaries, except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company and each of its Subsidiaries hold all licenses, franchises, permits, certificates, approvals and
authorizations from Governmental Authorities (“Permits”) necessary for the lawful conduct of their respective businesses, except where the failure to hold the same would not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect. 
 (b) The Company, each of its Subsidiaries, and each of their officers, directors, employees and, to the
Company’s Knowledge, agents acting on their behalf is, and has been, in compliance in all material respects with (x) all applicable trade, export control, import, and antiboycott laws and regulations, including the U.S. Export
Administration Regulations (15 C.F.R. Parts 730-774), (y) the Foreign Corrupt Practices Act of 1977 and any rules and regulations promulgated thereunder, and any other Laws applicable to the Company and its
Subsidiaries that address the prevention of corruption or bribery, and (z) all laws, regulations, orders or other financial restrictions administered by the Office of Foreign Assets Control of the United States Treasury Department
(“OFAC”), including OFAC’s Specially Designated Nationals List, U.S. sanctions related to or administered by the U.S. Department of State. Except as would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect, neither the Company nor any of its Subsidiaries maintain or need any national security clearance or authorization to access classified information or facilities to perform any current business or proposed business. 

Section 3.09 Tax Matters. Except as would not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect: (a) the Company and each of its Subsidiaries has prepared (or caused to be prepared) and timely filed (taking into account valid extensions of time within which to file) all Tax Returns required to be filed by any of them, and
all such filed Tax Returns (taking into account all amendments thereto) are true, complete and accurate, (b) all Taxes owed by the Company and each of its Subsidiaries that are due (whether or not shown on any Tax Return) have been timely paid
except for Taxes which are being contested in good faith by appropriate proceedings and which have been adequately reserved against in accordance with GAAP, (c) the Company is not currently subject to, and has not received in written notice
that it is subject to, any examination or audit by any Governmental Authority of any Tax Return relating to any Taxes of the Company or any of its Subsidiaries or with respect to any Taxes due from or with respect to the Company or any of its
Subsidiaries and (d) none of the Company or any of its Subsidiaries has engaged in, or has any liability or obligation with respect to, any “listed transaction” within the meaning of Treasury Regulations
Section 1.6011-4(b)(2). 
 Section 3.10 No Rights Agreement; Anti-Takeover
Provisions. (a) The Company is not party to a stockholder rights agreement, “poison pill” or similar anti-takeover agreement or plan. 

(b) The Board has taken all necessary actions to ensure that no restrictions included in any “control share acquisition,” “fair
price,” “moratorium,” “business combination” or other state anti-takeover Law (including the Texas Business Organizations Code) is, or as of the Closing will be, applicable to the Purchase, the conversion of Series A
Preferred Stock into Common Stock or the conversion of Series B Preferred Stock into Series A Preferred Stock. 

  
 15 

 Section 3.11 Brokers and Other Advisors. Except for RBC
Capital Markets, LLC, the fees and expenses of which will be paid by the Company, no broker, investment banker, financial advisor or other Person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or
commission, or the reimbursement of expenses in connection therewith, in connection with the Transactions based upon arrangements made by or on behalf of the Company or any of its Subsidiaries. 

Section 3.12 Sale of Securities. Assuming the accuracy of the representations and warranties set forth in
Section 4.08, the sale of the shares of Preferred Stock pursuant to this Agreement is exempt from the registration and prospectus delivery requirements of the Securities Act and the rules and regulations thereunder. Without
limiting the foregoing, neither the Company nor, to the Knowledge of the Company, any other Person authorized by the Company to act on its behalf, has engaged in a general solicitation or general advertising (within the meaning of Regulation D of
the Securities Act) of investors with respect to offers or sales of Preferred Stock, and neither the Company nor, to the Knowledge of the Company, any Person acting on its behalf has made any offers or sales of any security or solicited any offers
to buy any security, under circumstances that would cause the offering or issuance of Preferred Stock under this Agreement to be integrated with prior offerings by the Company for purposes of the Securities Act that would result in none of
Regulation D or any other applicable exemption from registration under the Securities Act to be available, nor will the Company take any action or steps that would cause the offering or issuance of Preferred Stock under this Agreement to be
integrated with other offerings by the Company. 
 Section 3.13 Listing and Maintenance Requirements. The Common Stock
is registered pursuant to Section 12(b) of the Exchange Act and listed on NASDAQ, and the Company has taken no action designed to, or which to the Knowledge of the Company is reasonably likely to have the effect of, terminating the registration
of the Common Stock under the Exchange Act or delisting the Common Stock from NASDAQ, nor has the Company received as of the date of this Agreement any notification that the SEC or NASDAQ is contemplating terminating such registration or listing.

 Section 3.14 Status of Securities. As of the Closing, the Acquired Shares and the shares of Series A Preferred Stock
and Common Stock issuable upon conversion of any of the foregoing shares will be, when issued, duly authorized by all necessary corporate action on the part of the Company, validly issued, fully paid and nonassessable and issued in compliance with
all applicable federal and state securities Laws and will not be subject to preemptive rights of any other stockholder of the Company, and will be free and clear of all Liens, except restrictions imposed by the Securities Act,
Section 5.08 and any applicable securities Laws. The shares of Common Stock issuable upon conversion of the Series A Preferred Stock and the shares of Series A Preferred Stock issuable upon conversion of the Series B
Preferred Stock have been duly reserved for issuance. The respective designations, powers, relative rights, qualifications, preferences, limitations and restrictions of the Preferred Stock and the Common Stock are as stated in the Company Charter
Documents (including the Certificates of Designations) or as otherwise provided by applicable Law. 

  
 16 

 Section 3.15 Ability to Pay Dividends. The Company is not party to any
material Contract, and is not subject to any provision in the Company Charter Documents or resolutions of the Board that, in each case, by its terms prohibits or prevents the Company from paying dividends in form and the amounts contemplated by the
Certificates of Designations. The Company and its Subsidiaries have no outstanding indebtedness for borrowed money. 
 Section 3.16
No Other Company Representations or Warranties. Except for the representations and warranties made by the Company in this Article III and in any certificate or other document delivered in connection with this
Agreement, neither the Company nor any other Person acting on its behalf makes any other express or implied representation or warranty with respect to the Preferred Stock, the Common Stock, the Company or any of its Subsidiaries or their respective
businesses, operations, properties, assets, liabilities, condition (financial or otherwise) or prospects, notwithstanding the delivery or disclosure to the Investor or its Representatives of any documentation, forecasts or other information with
respect to any one or more of the foregoing, and the Investor acknowledges the foregoing. In particular, and without limiting the generality of the foregoing, except for the representations and warranties made by the Company in this Article
III and in any certificate or other document delivered in connection with this Agreement, neither the Company nor any other Person makes or has made any express or implied representation or warranty to the Investor or its Representatives with
respect to (a) any financial projection, forecast, estimate, budget or prospect information relating to the Company, any of its Subsidiaries or their respective businesses or (b) any oral or written information presented to the Investor or
its Representatives in the course of its due diligence investigation of the Company, the negotiation of this Agreement or the course of the Transactions or any other transactions or potential transactions involving the Company and the Investor. 

Section 3.17 No Other Investor Representations or Warranties. Except for the representations and
warranties expressly set forth in Article IV and in any certificate or other document delivered in connection with this Agreement, the Company hereby acknowledges that no Investor nor any other Person, (a) has made or is making any other
express or implied representation or warranty with respect to such Investor or any of its Subsidiaries or their respective businesses, operations, assets, liabilities, condition (financial or otherwise) or prospects, including with respect to any
information provided or made available to the Company or any of its Representatives or any information developed by the Company or any of its Representatives or (b) except in the case of fraud, will have or be subject to any liability or
indemnification obligation to the Company resulting from the delivery, dissemination or any other distribution to the Company or any of its Representatives, or the use by the Company or any of its Representatives, of any information, documents,
estimates, projections, forecasts or other forward-looking information, business plans or other material developed by or provided or made available to the Company or any of its Representatives, including in due diligence materials, in anticipation
or contemplation of any of the Transactions or any other transactions or potential transactions involving the Company and the Investor. The Company, on behalf of itself and on behalf of its respective Affiliates, expressly waives any such claim
relating to the foregoing matters, except with respect to fraud. 

  
 17 

 ARTICLE IV 

Representations and Warranties of the Investor 

The Investor represents and warrants to the Company, as of the date hereof and as of the Closing Date: 

Section 4.01 Organization; Standing. The Investor is a limited partnership duly organized, validly existing and in good
standing under the Laws of its jurisdiction of organization and the Investor has all requisite power and authority necessary to carry on its business as it is now being conducted and is duly licensed or qualified to do business and is in good
standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so
licensed, qualified or in good standing would not, individually or in the aggregate, reasonably be expected to have an Investor Material Adverse Effect. 

Section 4.02 Authority; Noncontravention. (a) The Investor has all necessary power and authority to execute and deliver this
Agreement and the other Transaction Documents, to perform its obligations hereunder and thereunder and to consummate the Transactions. The execution, delivery and performance by the Investor of this Agreement and the other Transaction Documents and
the consummation by such Investor of the Transactions have been duly authorized and approved by all necessary action on the part of such Investor, and no further action, approval or authorization by any of its stockholders, partners, members or
other equity owners, as the case may be, is necessary to authorize the execution, delivery and performance by such Investor of this Agreement and the other Transaction Documents and the consummation by the Investor of the Transactions. This

prior to such Transfer for the express benefit of the Company (in form and substance reasonably satisfactory to the Company and with a copy thereof to be furnished to the Company) to be bound by the terms of this Agreement and if the transferee and
the transferor agree for the express benefit of the Company that the transferee shall Transfer the Preferred Stock or Common Stock so Transferred back to the transferor at or before such time as the transferee ceases to be a Permitted Transferee of
the transferor;

(vi) Transfers in connection with a total return swap or bona fide loan or other financing arrangement, in each case entered
into with a nationally recognized financial institution, including a pledge to such a financial institution to secure a bona fide debt financing and any foreclosure by such financial institution or transfer to such financial institution in lieu of
foreclosure and subsequent sale of the securities (each, a “Permitted Loan”), as long as such financial institution agrees with the relevant Investor Party (with the Company as an express third party beneficiary of such agreement)
that following such foreclosure or in connection with such transfer it shall not directly or indirectly Transfer (other than pursuant to a broadly distributed offering or a sale effected through a broker-dealer), as the case may be, Preferred Stock

foregoing (other than, for the avoidance of doubt, an Investor Party or its Affiliates) shall be entitled to any rights or have any obligations or be subject to any transfer restrictions or limitations hereunder except and to the extent for those
expressly provided for in Registration Rights Agreement; and 
 (vii) Transfers to a third party for cash solely to the
extent that all of the net proceeds of such sale are solely used to be posted as collateral (which term, for the avoidance of doubt, shall include any such posting in connection with a margin call) pursuant to a Permitted Loan, or to repay a
Permitted Loan to the extent necessary to satisfy a requirement to post collateral with respect to such Permitted Loan or avoid a bona fide margin call on such Permitted Loan or to repay such Permitted Loan in the event of a mandatory prepayment
event thereunder; provided that such sale shall not result in proceeds in excess of $30,000,000.

fide, broadly distributed underwritten public offering or a bona fide, broadly distributed firm commitment offering to one or more broker-dealers for resale under Rule 144A and/or Regulation S of the Securities Act or a sale to a broker-dealer under
Rule 144 the Securities Act, (y) in a private transaction outside of the public markets or (z) to any partner, member or stockholder of an Investor Party or its Affiliates.

THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF
ANY STATE AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A REGISTRATION STATEMENT RELATING THERETO IS IN EFFECT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT
OR SUCH LAWS. 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO TRANSFER AND OTHER RESTRICTIONS SET FORTH IN AN INVESTMENT
AGREEMENT, DATED AS OF JANUARY 14, 2019, COPIES OF WHICH ARE ON FILE WITH THE SECRETARY OF THE ISSUER. 
 (b) Upon request of the
applicable Investor Party, upon receipt by the Company of an opinion of counsel reasonably satisfactory to the Company to the effect that such legend is no longer required under the Securities Act and applicable state securities laws, the Company
shall promptly cause the first paragraph of the legend to be removed from any certificate for any Preferred Stock or Common Stock to be Transferred in accordance with the terms of this Agreement and the second paragraph of the legend shall be
removed upon the expiration of such transfer and other restrictions set forth in this Agreement (and, for the avoidance of doubt, immediately prior to any termination of this Agreement). 

Section 5.10 Election of Directors. 

(a) Effective as of the Closing, the Company will increase the size of the Board in order to elect or appoint two Investor Designees (such
individuals, the “Initial Investor Director Designees”) to the Board to serve for a term expiring at the 2019 annual meeting of the Company’s stockholders and until their successors are duly elected and qualified. The Company
agrees to include each of the Initial Investor Director Designees (or their successors) as an “Investor Designee” nominated for election (in accordance with Section 14 of the Series A Certificate of Designations) to the Board on the
slate of nominees recommended by the Board in the Company’s proxy statement relating to the 2019 annual meeting of the Company’s stockholders, to serve for a term expiring at the next annual meeting of the Company’s stockholders and
until his or her successor is duly elected and qualified. Upon election to the Board, the Company agrees to promptly appoint one Investor Designee to serve on each committee of the Board (other than the Audit Committee), subject in each case to
meeting the applicable requirements for service on such committee as set forth in the listing rules of NASDAQ, the Company’s corporate governance guidelines applicable to all of the members of such committee and such committee’s charter.
For the avoidance of doubt, the Initial Investor 

  
 31 

 
Director Designees shall serve on the Board effective immediately following the Closing; provided, that if the Investor has not informed the Company of its selection for one or both of its
Initial Investor Director Designees as of such time, then the Company will promptly after receiving a written notice that such Initial Investor Director Designee or Initial Investor Director Designees has been selected, elect or appoint such Initial
Investor Director Designee or Initial Investor Director Designees to the Board, subject to the terms of this Section 5.10 and the Certificates of Designations. 

(b) If at any time the 10% Beneficial Ownership Requirement is not satisfied (but the Fall-Away of Investor Board Rights has not occurred),
then (i) at the written request of the Board, one of the Investor Directors, as specified by the Investor Parties (or, if the Investor Parties fail to so specify within ten (10) days of such requirement not being satisfied, as specified by
the Board), shall immediately resign, and the Investor Parties shall cause such Investor Director immediately to resign, from the Board effective as of the first date on which the 10% Beneficial Ownership Requirement ceases to be satisfied, and
(ii) the Investor shall have the right to designate only one Investor Designee during the time that the 10% Beneficial Ownership Requirement is not satisfied (but the Fall-Away of Investor Board Rights has not occurred). 

(c) Upon the occurrence of the Fall-Away of Investor Board Rights, at the written request of the Board, the Investor Directors shall
immediately resign, and the Investor Parties shall cause the Investor Directors immediately to resign, from the Board effective as of the date of the Fall-Away of Investor Board Rights, and the Investor Parties shall no longer have any rights under
this Section 5.10, including, for the avoidance of doubt, any designation and/or nomination rights under Section 5.10(d). 

(d) Until the occurrence of the Fall-Away of Investor Board Rights, at any annual meeting of the Company’s stockholders after the 2019
annual meeting of the Company’s stockholders at which the term of one or more Investor Directors shall expire, the Investor shall have the right to designate a number of Investor Designees not to exceed the number of Investor Directors whose
term expires at such annual meeting which Investor Designees will be nominated by the Company as “Investor Designees” for election (in accordance with Section 14 of the Series A Certificate of Designations) to the Board at such annual
meeting. The Company shall include each Investor Designee designated by the Investor in accordance with this Section 5.10(d) in the Company’s slate of nominees as “Investor Designees” (in accordance with
Section 14 of the Series A Certificate of Designations) for the applicable annual meeting of the Company’s stockholders and shall recommend that the holders of the Series A Preferred Stock vote in favor of such Investor Designees and shall
support the Investor Designees in a manner no less rigorous and favorable than the manner in which the Company supports its other nominees in the aggregate. Without the prior written consent of the Investor Parties, so long as an Investor Party is
entitled to designate any Investor Designee for election to the Board in accordance with this Section 5.10, the Board shall not remove any Investor Director from his or her directorship (except as required by law or the
Company Charter Documents), unless (x) the Investor’s right to designate Investor Designees for election to the Board (whether at any annual meeting of the Company’s stockholders or to fill a vacancy resulting from the death,
disability, resignation or removal of any Investor Director as a member of the Board) and the Company’s obligation to nominate such Investor Designees for election to the Board, in each case as set forth in this
Section 5.10 and (y) the rights of the holders of the Preferred Stock to elect such Investor Designees set forth in Section 14 of the Series A Certificate of Designations, in each case, are preserved or
(z) the Investor Parties request in writing the removal of an Investor Designee (such removal to be in accordance with the Series A Certificate of Designations). 

  
 32 

 (e) In the event of the death, disability, resignation or removal of any Investor Director
as a member of the Board (other than resignation pursuant to Section 5.10(b) or 5.10(c)), the Investor Parties, if they are entitled to nominate one or more directors pursuant to this
Section 5.10, may designate an Investor Designee to replace such Investor Director and, subject to Section 5.10(f) and any applicable provisions of the Texas Business Organizations Code, the
Company shall cause such Investor Designee to fill such resulting vacancy. 
 (f) The Company’s obligations to have any Investor
Designee elected to the Board or nominate any Investor Designee for election as a director at any meeting of the Company’s stockholders pursuant to this Section 5.10, as applicable, shall in each case be subject to
(A) such Investor Designee’s satisfaction of all requirements regarding service as a director of the Company under applicable Law and stock exchange rules regarding service as a director of the Company and all other criteria and
qualifications for service as a director applicable to all directors of the Company and (B) such Investor Designee meeting all applicable independence requirements under the listing rules of NASDAQ; provided, that in no event shall such
Investor Designee’s relationship with the Investor Parties or their Affiliates (or any other actual or potential lack of independence resulting therefrom), in and of itself, be considered to disqualify such Investor Designee from being a member
of the Board pursuant to this Section 5.10. The Investor Parties will cause each Investor Designee to make himself or herself reasonably available for interviews and to consent to such reference and background checks or
other investigations as the Board may reasonably request to determine the Investor’s Designee’s eligibility and qualification to serve as a director of the Company. No Investor Designee shall be eligible to serve on the Board if he or she
has been involved in any of the events enumerated under Item 2(d) of Schedule 13D under the Exchange Act or Item 401(f) of Regulation S-K under the Securities Act or is subject to any Judgment prohibiting
service as a director of any public company. As a condition to any Investor Designee’s election to the Board or nomination for election as a director of the Company at any meeting of the Company’s stockholders, the Investor Parties and the
Investor Designee must provide to the Company: 
 (i) all information requested by the Company that is required to be or is
customarily disclosed for directors, candidates for directors and their respective Affiliates and Representatives in a proxy statement or other filings in accordance with applicable Law, any stock exchange rules or listing standards or the Company
Charter Documents or corporate governance guidelines, in each case, relating to the Investor Designee’s election as a director of the Company or the Company’s operations in the ordinary course of business; 

(ii) all information requested by the Company in connection with assessing eligibility, independence and other criteria
applicable to directors or satisfying compliance and legal or regulatory obligations, in each case, relating to the Investor Designee’s nomination or election, as applicable, as a director of the Company or the Company’s operations in the
ordinary course of business; 

  
 33 

 (iii) an undertaking in writing by the Investor Designee to be subject to,
bound by and duly comply with the code of conduct in the form agreed upon by the other directors of the Company, provided, that no such code of conduct shall restrict any transfer of securities by the Investor Parties or their Affiliates
(other than with respect to any Investor Director solely in his or her individual capacity) except as provided herein, impose confidentiality obligations on any Investor Director other than Section 5.05 or as mandatorily
applicable under applicable law, or impose any share ownership requirement for any Investor Director. 
 (g) The Company shall indemnify the
Investor Directors and provide the Investor Directors with director and officer insurance to the same extent as it indemnifies and provides such insurance to other members of the Board, pursuant to the Company Charter Documents, the Texas Business
Organizations Code or otherwise. The Company acknowledges and agrees that it (1) is the indemnitor of first resort (i.e., its obligations to the Investor Directors are primary and any obligation of the Investor Parties or their Affiliates to
advance expenses or to provide indemnification for the same expenses or liabilities incurred by the Investor Directors are secondary), and (2) shall be required to advance the amount of expenses incurred by the Investor Directors and shall be
liable for the amount of all expenses and liabilities incurred by the Investor Directors, in each case to the same extent as it indemnifies and provides such insurance to other members of the Board, pursuant to the Company Charter Documents, the
Texas Business Organizations Code or otherwise, without regard to any rights the Investor Directors may have against any Investor Parties or their Affiliates. 

(h) Prior to the Fall-Away of Investor Board Rights, (i) the Company shall not increase the size of the Board to more than a total of 8
director seats; provided, that the Company may, with the consent of the Investor Parties (such consent not to be unreasonably withheld, conditioned or delayed), temporarily increase the size of the Board to facilitate the retirement or
resignation of any incumbent director and the replacement thereof with a new director, and (ii) the Company shall not decrease the size of the Board if such decrease would require the resignation of either or both Investor Designees, in each
case without the consent of the Investor Parties. 
 (i) Prior to the Fall Away of Investor Board Rights, any proposed transaction between
the Company and the Investor Party or any Affiliates thereof must be approved in accordance with the stated policy in effect at the time regarding transactions or courses of dealing with related parties. 

(j) The Investor Directors shall be reimbursed for
out-of-pocket expenses incurred in connection with participation as a member of the Board in a manner consistent with the Company’s policies for reimbursing other
outside members of the Board.

to the Investor Parties any such information the Investor Parties may reasonably request in order to evaluate the proposed issuance, except that the Company shall not be required to deliver any information that has not been or will not be provided
or otherwise made available to the proposed purchasers of the Proposed Securities; and 
 (ii) offer to issue and sell to the
Investor Parties, on such terms as the Proposed Securities are issued and upon full payment by the Investor Parties, a portion of the Proposed Securities equal to a percentage determined by dividing (A) the number of shares of Common Stock the
Investor Parties beneficially own (on an as converted basis) by (B) the total number of shares of Common Stock then outstanding (on an as-converted basis) (such percentage, an Investor Party’s
“Participation Portion”); provided, however, that, subject to compliance with the terms and conditions set forth in Section 5.16(g), the Company shall not be required to offer to issue or sell
to the Investor Parties (or to any of 

  
 39 

 
them) the portion of the Proposed Securities that would require the Company to obtain stockholder approval in respect of the issuance of any Proposed Securities under the listing rules of NASDAQ
or any other securities exchange or any other applicable Law (provided, further, however, that the Company shall still be obligated to provide written notice of such proposed issuance to the Investor Parties pursuant to
Section 5.16(b)(i), which notice shall include a description of the Proposed Securities (including the number thereof) that would require stockholder approval in respect of the issuance thereof (the “Restricted
Issuance Information”)). 
 (c) The Investor Parties will have the option, exercisable by written notice to the Company, to accept
the Company’s offer and commit to purchase any or all of the equity securities offered to be sold by the Company to the Investor Parties, which notice must be given within seven (7) Business Days after receipt of such notice from the
Company (or such shorter period if the notice by the Company was sent in accordance with the preceding paragraph less than seven (7) Business Days prior to the proposed issuance date, and in no event less than two (2) Business Days). If
the Company offers two (2) or more securities in units to the other participants in the offering, the Investor Parties must purchase such units as a whole and will not be given the opportunity to purchase only one (1) of the securities
making up such unit. The closing of the exercise of such subscription right shall take place simultaneously with the closing of the sale of the Proposed Securities giving rise to such subscription right; provided, however, that the
closing of any purchase by any such Investor Party may be extended beyond the closing of the sale of the Proposed Securities giving rise to such preemptive right to the extent necessary to (i) obtain required approvals from any Governmental
Authority or (ii) permit the Investor Parties to receive proceeds from calling capital pursuant to commitments made by its (or its affiliated investment funds’) limited partners. Upon the expiration of the offering period described above,
the Company will be free to sell such Proposed Securities that the Investor Parties have not elected to purchase during the 90 days following such expiration on terms and conditions no more favorable to the purchasers thereof than those offered to
the Investor Parties in the notice delivered in accordance with Section 5.16(b). Any Proposed Securities offered or sold by the Company after such 90-day period must be reoffered to issue or sell to the Investor Parties
pursuant to this Section 5.16; provided, that, subject to compliance with the terms and conditions set forth in Section 5.16(g), the Company shall not be required to reoffer to the Investor
Parties (or to any of them) the portion of the Proposed Securities that would require the Company to obtain stockholder approval in respect of the issuance of any Proposed Securities under the listing rules of NASDAQ or any other securities exchange
or any applicable Law. 
 (d) The election by any Investor Party not to exercise its subscription rights under this
Section 5.16 in any one instance shall not affect their right as to any subsequent proposed issuance. 
 (e)
Notwithstanding anything in this Section 5.16 to the contrary, the Company will not be deemed to have breached this Section 5.16 if not later than thirty (30) Business Days following the
issuance of any Proposed Securities in contravention of this Section 5.16, the Company or the transferee of such Proposed Securities offers to sell a portion of such equity securities or additional equity securities of the
type(s) in question to each Investor Party so that, taking into account such previously-issued Proposed Securities and any such additional Proposed Securities, each Investor Party will have had the right to purchase or subscribe for Proposed
Securities in a manner consistent with the allocation and other terms and upon same economic and other terms provided for in Sections 5.16(b) and 5.16(c). 

  
 40 

 (f) In the case of an issuance subject to this Section 5.16 for
consideration in whole or in part other than cash, including securities acquired in exchange therefor (other than securities by their terms so exchangeable), the consideration other than cash shall be deemed to be the Fair Market Value thereof. 

(g) In the event that the Company is not required to offer or reoffer to the Investor Parties any Proposed Securities because such issuance
would require the Company to obtain stockholder approval in respect of the issuance of any Proposed Securities under the listing rules of NASDAQ or any other securities exchange or any other applicable Law, the Company shall, upon the Investor
Parties’ reasonable request delivered to the Company in writing within no later than seven (7) Business Days following its receipt of the written notice of such issuance to the Investor Parties pursuant to
Section 5.16(b)(i) (together with the Restricted Issuance Information), at the Investor Parties’ election: 

(i) waive the restrictions set forth in Section 5.07(a) solely to the extent necessary to permit any
Investor Party to acquire such number of securities of the Company (including Common Stock) equivalent to its Participation Portion of the Proposed Securities such Investor Party would have been entitled to purchase had it been in entitled to
acquire such Proposed Securities pursuant to Section 5.16(c) (provided, that such request by Investor Parties shall not be deemed to be a violation of Section 5.07(j)); 

(ii) consider and discuss in good faith modifications proposed by the Investor Parties to the terms and conditions of such
portion of the Proposed Securities which would otherwise be issued to the Investor Parties such that the Company would not be required to obtain stockholder approval in respect of the issuance of such Proposed Securities as so modified; and/or 

(iii) solely to the extent that stockholder approval is required in connection with the issuance of equity securities to
Persons other than the Investor Parties, take such actions as may be reasonably necessary to seek stockholder approval in respect of the issuance of any Proposed Securities to the Investor Parties. 

Section 5.17 Section 16 Matters. If the Company becomes a party to a consolidation, merger or other similar
transaction, or if the Company proposes to take or omit to take any other action under Section 5.16 (including granting to the Investor or its Affiliates the right to participate in any issuance of securities) or otherwise or if there is any
event or circumstance that may result in the Investor Parties, their respective Affiliates and/or any Investor Director being deemed to have made a disposition or acquisition of equity securities of the Company or derivatives thereof for purposes of
Section 16 of the Exchange Act (including the purchase by the Investor Parties of any securities under Section 5.16), and if any Investor Director is serving on the Board at such time or has served on the Board during the preceding six
months (i) the Board or a committee thereof composed solely of two or more “non-employee directors” as defined in Rule 16b-3 of the Exchange Act will pre-approve such acquisition or disposition of equity securities of the Company or derivatives thereof for the express purpose of 

  
 41 

 
exempting the Investor Parties’, their respective Affiliates’ and any Investor Director’s interests (for the Investor and/or their respective Affiliates, to the extent such persons
may be deemed to be “directors by deputization”) in such transaction from Section 16(b) of the Exchange Act pursuant to Rule 16b-3 thereunder and (ii) if the transaction involves (A) a
merger or consolidation to which the Company is a party and the Common Stock is, in whole or in part, converted into or exchanged for equity securities of a different issuer, (B) a potential acquisition or deemed acquisition, or disposition or
deemed disposition, by the Investor Parties, the Investor’s Affiliates, and/or any Investor Director of equity securities of such other issuer or derivatives thereof and (C) an Affiliate or other designee of the Investor Parties or their
Affiliates will serve on the board of directors (or its equivalent) of such other issuer pursuant to the terms of an agreement to which the Company is a party (or if the Investor Parties notify the Company of such service a reasonable time in
advance of the closing of such transactions), then if the Company requires that the other issuer pre-approve any acquisition of equity securities or derivatives thereof for the express purpose of exempting the
interests of any director or officer of the Company or any of its subsidiaries in such transactions from Section 16(b) of the Exchange Act pursuant to Rule 16b-3 thereunder, the Company shall require that
such other issuer pre-approve any such acquisitions of equity securities or derivatives thereof for the express purpose of exempting the interests of the Investor Parties’, their respective
Affiliates’ and any Investor Director (for the Investor Parties and/or their respective Affiliates, to the extent such persons may be deemed to be “directors by deputization” of such other issuer) in such transactions from
Section 16(b) of the Exchange Act pursuant to Rule 16b-3 thereunder. 
 Section 5.18
Proxy Statement. The Company agrees at the 2019 annual meeting of the stockholders of the Company (the “Stockholder Meeting”) to include in its proxy statement prepared and filed with the SEC (the “Proxy
Statement”) a proposal to approve the issuance of shares of Common Stock to the Investor Parties in connection with any future conversion or redemption of the Preferred Stock into Common Stock, including after giving effect to the
conversion of shares of Series B Preferred Stock into shares of Series A Preferred Stock in accordance with the terms of such Preferred Stock, and in connection with any issuance of Common Stock pursuant to, or upon conversion, exercise or exchange
of, any securities issued pursuant to Section 5.16 that would absent such approval violate NASDAQ Listing Rule 5635, including without limitation deleting the effectiveness of Section 6(c) of the Series A
Preferred Certificate of Designation (the “Stockholder Approval”). Subject to the directors’ fiduciary duties, the Proxy Statement shall include the Board’s recommendation that the stockholders vote in favor of the
Stockholder Approval. The Company shall use commercially reasonable efforts to solicit from the stockholders proxies in favor of the Stockholder Approval and to obtain the Stockholder Approval. The Investor acknowledges that no votes of the shares
of Series A Preferred Stock sold and issued in the Private Placement will be counted toward Stockholder Approval in compliance with NASDQ Listing Rule 5635. The Investor and its Affiliates agree to furnish to the Company all information concerning
the Investor and its Affiliates as the Company may reasonably request in connection with any such Stockholder Meeting. The Company shall respond reasonably promptly to any comments received from the SEC with respect to the Proxy Statement, and the
Company shall cause the Proxy Statement to be mailed to the Company’s stockholders at the earliest reasonably practicable date. The Company shall provide to the Investor, as promptly as reasonably practicable after receipt thereof, any written
comments from the SEC or any written request from the SEC or its staff for amendments or supplements to the Proxy Statement and shall provide the Investor with copies of all correspondence between the

  
 42 

 
Company, on the one hand, and the SEC and its staff, on the other hand, relating to the Proxy Statement. Notwithstanding anything to the contrary stated above, prior to filing or mailing the
Proxy Statement (or, in each case, any amendment or supplement thereto) or responding to any comments of the SEC or its staff with respect thereto, the Company shall provide the Investor Parties with a reasonable opportunity to review and comment on
such document or response. 
 Section 5.19 Financing Cooperation. If requested by the Investor Parties, the Company will
provide the following cooperation in connection with the Investor Parties obtaining any Permitted Loan: (i) entering into an issuer agreement (an “Issuer Agreement”) with each lender in customary form in connection with such
transactions (which agreement may include, without limitation, agreements and obligations of the Company relating to procedures and specified time periods for effecting transfers and/or conversions upon foreclosure, agreements to not hinder or delay
exercises of remedies on foreclosure, acknowledgments regarding corporate policy, if applicable, and certain acknowledgments regarding securities law status of the pledge arrangements) and subject to the consent of the Company (which will not be
unreasonably withheld or delayed), with such changes thereto as are reasonably requested by such lender and customary for similar financings, (ii) using commercially reasonable efforts to (A) remove any restrictive legends on certificates
representing pledged Preferred Stock and depositing such pledged Preferred Stock in book entry form on the books of The Depository Trust Company when eligible to do so or (B) without limiting the generality of clause (A), if such Preferred
Stock is eligible for resale under Rule 144A, depositing such pledged Preferred Stock in book entry form on the books of The Depository Trust Company or other depository with customary restrictive legends, (iii) if so requested by such lender
or counterparty, as applicable, re-registering the pledged Preferred Stock in the name of the relevant lender, counterparty, custodian or similar party to a Permitted Loan, with respect to Permitted Loans
solely as securities intermediary and only to the extent an Investor Party or its Affiliates continues to beneficially own such pledged Preferred Stock, (iv) entering into customary triparty agreements with each lender and the Investor Parties
relating to the delivery of the Preferred Stock to the relevant lender for crediting to the relevant collateral accounts upon funding of the loan and payment of the purchase price including a right for such lender as a third party beneficiary of the
Company’s obligations hereunder to issue the Preferred Stock upon payment of the purchase therefor in accordance with the terms of this Agreement and (v) such other cooperation and assistance as the Investor Parties may reasonably request
(which cooperation and assistance, for the avoidance of doubt, shall not include any requirements that the Company deliver information, compliance certificates or any other materials typically provided by borrowers to lenders) that will not
unreasonably disrupt the operation of the Company’s business. Anything in the preceding sentence to the contrary notwithstanding, the Company’s obligation to deliver an Issuer Agreement is conditioned on (x) the Investor Parties
delivering to the Company a copy of the loan agreement for the Permitted Loan to which the Issuer Agreement relates and (y) the Investor certifying to the Company in writing that (A) the loan agreement with respect to which the Issuer
Agreement is being delivered constitutes a Permitted Loan being entered into in accordance with this Agreement, the Investor has pledged the Preferred Stock and/or the shares of Common Stock underlying the Series A Preferred Stock as collateral to
the lenders under such Permitted Loan and that the execution of such Permitted Loan and the terms thereof do not violate the terms of this Agreement, (B) to the extent applicable, whether the registration rights under the Registration Rights
Agreement are being assigned to the lenders under that Permitted Loan and (C) the Investor Parties acknowledge and 

  
 43 

 
agree that the Company will be relying on such certificate when entering into the Issuer Agreement and any inaccuracy in such certificate will be deemed a breach of this Agreement. The Investor
Parties acknowledge and agree that the statements and agreements of the Company in an Issuer Agreement are solely for the benefit of the applicable lenders party thereto and that in any dispute between the Company and the Investor Parties under this
Agreement the Investor Parties shall not be entitled to use the statements and agreements of the Company in an Issuer Agreement against the Company. Upon request by the Investor Parties, the Company shall consider in good faith any amendments to
this Agreement, the Series A Certificate of Designations and/or the Series B Certificate of Designations proposed by the Investor Parties necessary to facilitate the consummation of a Permitted Loan, and the Company shall consent to any such
amendment that is not adverse in any respect to the interests of the Company (as determined by the Company in its sole discretion upon the authorization of the disinterested members of the Board).

provided, that the right to terminate this Agreement under this Section 7.01(b) shall not be available to any party if the breach by such party of its representations and warranties set forth in this Agreement or the

reason of, the transactions contemplated hereby or in respect of any representations made or alleged to be made in connection herewith, and no personal liability shall attach to, be imposed upon or otherwise be incurred by the Non-Recourse Parties through the Investor or otherwise, whether by or through attempted piercing of the corporate (or partnership or limited liability company) veil, by the enforcement of any assessment or by any

of New York in the State of New York and the parties hereto hereby irrevocably submit to the exclusive jurisdiction and venue of such courts in any such Action and irrevocably waive the defense of an inconvenient forum or lack of jurisdiction to the
maintenance of any such Action. The consents to jurisdiction and venue set forth in this Section 8.06 shall not constitute general consents to service of process in the State of New York and shall have no effect for any
purpose except as provided in this paragraph and shall not be deemed to confer rights on any Person other than the parties hereto. Each party hereto agrees that service of process upon such party in any Action arising out of or relating to this

be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law; provided, however, that nothing in the foregoing shall restrict any party’s rights to seek any post-judgment relief
regarding, or any appeal from, a final trial court judgment. 

  
 49 

 Section 8.07 Specific Enforcement. The parties hereto agree that

 “VWAP” per share of Common Stock on any
Trading Day means the per share volume-weighted average price as displayed under the heading Bloomberg VWAP on Bloomberg (or, if Bloomberg ceases to publish such price, any successor service reasonably chosen by the Company) page “ZIXI
<equity> AQR” (or its equivalent successor if such page is not available) in respect of the period from the open of trading on the relevant Trading Day until the close of trading on such Trading Day (or if such volume-weighted average
price is unavailable, the market price of one share of Common Stock on such Trading Day determined, using a volume-weighted average method, by an Independent Financial Advisor retained for such purpose by the Company). 

SECTION 4. Accreted Value; Dividends. (a) Each share of Series A Preferred Stock will have an initial stated liquidation value
equal to the Stated Value. From the Original Issuance Date, the Stated Value per share of Series A Preferred Stock will accrete at the Rate of Accretion, compounded quarterly on each March 31, June 30, September 30 and on
December 31 of each year during which any shares of Series A Preferred Stock remain outstanding (each a “Quarterly Calculation Date”), beginning on the Quarterly Calculation Date immediately following the Original
Issuance Date (the Stated Value per share as it has accreted as of any date, the “Accreted Value”, subject to appropriate adjustment in the event of any stock dividend, stock split, stock distribution or combination, consolidation,
subdivision, reclassification or other corporate actions having the similar effect with respect to the Series A Preferred Stock). All calculations of Accreted Value will be computed on the basis of a 360-day
year of twelve 30-day months. Notwithstanding the foregoing, each share of Series A Preferred Stock issued in connection with the conversion of shares of Series B Preferred Stock in accordance with the terms
of the Series B Preferred Stock shall be deemed to have the same Accreted Value as of the date such share of Series A Preferred Stock is issued (the “Conversion Date”) as the Accreted Value as of the Conversion Date of a share of
Series A Preferred stock that was issued on the Original Issuance Date.

 (b) Participating Dividends. The Holders shall also be entitled to receive, when, as
and if declared by the Board, dividends per share of Series A Preferred Stock of an amount equal to the aggregate amount of any dividends or other distributions, whether cash, in kind or other property (including, for the avoidance of doubt, any
securities), paid on outstanding shares of Common Stock on a per share basis based on the number of shares of Common Stock into which such share of Series A Preferred Stock could be converted on the applicable record date for such dividends or other
distributions, assuming such shares of Common Stock were outstanding on the applicable record date for such dividend or other distributions (the “Participating Dividends”). Participating Dividends shall be payable as and when paid
to the holders of shares of Common Stock. Participating Dividends are payable on a cumulative basis once declared, whether or not there shall be funds legally available for the payment thereon. The Company shall not declare or pay any dividends on
shares of Common Stock unless the holders of the Series A Preferred Stock then outstanding shall simultaneously receive Participating Dividends on a pro rata basis as if the shares of Series A Preferred Stock had been converted into shares of Common
Stock immediately prior to the record date for determining the stockholders eligible to receive such dividends. If the Company distributes any rights pursuant to any stockholder rights plan on or after the date hereof, then such distribution will
not require a Participating Dividend except to the extent provided in the immediately following sentence. If any shares of Common Stock are issued upon conversion of any share of Series A Preferred Stock and, at the time of such conversion, the
Company has in effect any stockholder rights plan, then the holder of such share of Series A Preferred Stock will be entitled to receive, in addition to, and concurrently with the delivery of, the consideration otherwise payable under this
Certificate of Designations upon such conversion, the rights set forth in such stockholder rights plan, unless such rights have separated from the shares of Common Stock at such time, in which case such separation will require, at the time of such
separation, a Participating Dividend pursuant to this Section 4(b). 
 SECTION 5. Liquidation Rights.
(a) Liquidation. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, the Holders shall be entitled, out of assets legally available therefor, before any distribution or
payment out of the assets of the Company may be made to or set aside for the holders of any Junior Stock, and subject to the rights of the holders of any Senior Stock or Parity Stock and the rights of the Company’s existing and future
creditors, to receive in full a liquidating distribution in cash and in the amount per share of Series A Preferred Stock equal to the greater of (i) the Accreted Value with respect to such share of Series A Preferred Stock as of the date of
such voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company and (ii) the amount such Holders would have received had such Holders, immediately prior to such voluntary or involuntary liquidation,
dissolution or winding up of the affairs of the Company, converted such shares of Series A Preferred Stock into Common Stock (pursuant to Section 6 without regard to any of the limitations on convertibility contained
therein). Holders shall not be entitled to any further payments in the event of any such voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company other than what is expressly provided for in this
Section 5 and will have no right or claim to any of the Company’s remaining assets. 

  
 10 

 (b) Partial Payment. If in connection with any distribution described in
Section 5(a) above, the assets of the Company or proceeds therefrom are not sufficient to pay in full the aggregate liquidating distributions required to be paid pursuant to Section 5(a) to all
Holders and the liquidating distributions payable all holders of any Parity Stock, the amounts distributed to the Holders and to the holders of all such Parity Stock shall be paid pro rata in accordance with the respective aggregate liquidating
distributions to which they would otherwise be entitled if all amounts payable thereon were paid in full. 
 (c) Merger, Consolidation and
Sale of Assets Not Liquidation. For purposes of this Section 5, the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property and
assets of the Company shall not be deemed a voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, nor shall the merger, consolidation, statutory exchange or any other business combination transaction of the
Company into or with any other Person or the merger, consolidation, statutory exchange or any other business combination transaction of any other Person into or with the Company be deemed to be a voluntary or involuntary liquidation, dissolution or
winding up of the affairs of the Company. 
 SECTION 6. Right of the Holders to Convert. 

(a) Each Holder shall have the right, at such Holder’s option, subject to the conversion procedures set forth in
Section 8, to convert each share of such Holder’s Series A Preferred Stock at any time into (i) the number of shares of Common Stock equal to the product of (A) the Accreted Value with respect to such share
of Series A Preferred Stock as of the applicable Conversion Date multiplied by (B) the Conversion Rate as of the applicable Conversion Date divided by (C) 1,000 plus (ii) cash in lieu of fractional shares as set out in
Section 11(h). The right of conversion may be exercised as to all or any portion of such Holder’s Series A Preferred Stock from time to time; provided that, in each case, no right of conversion may be exercised
by a Holder in respect of fewer than 1,000 shares of Series A Preferred Stock (unless such conversion relates to all shares of Series A Preferred Stock held by such Holder). 

(b) The Company shall at all times reserve and keep available out of its authorized and unissued Common Stock, solely for issuance upon the
conversion of the Series A Preferred Stock, such number of shares of Common Stock as shall from time to time be issuable upon the conversion of all the shares of Series A Preferred Stock then outstanding. Any shares of Common Stock issued upon
conversion of Series A Preferred Stock shall be duly authorized, validly issued, fully paid and nonassessable. 
 (c) Notwithstanding the
foregoing or anything else in this Certificate of Designations to the contrary, unless and until the Stockholder Approval is obtained, the Holders shall not have the right to convert their shares of Series A Preferred Stock into shares of Common
Stock pursuant to the terms of this Certificate of Designation, and the Company shall not be required to issue shares of Common Stock pursuant to such conversion, in excess of the Share Cap (the “Conversion Restriction”); and the
Company shall either obtain Stockholder Approval of such issuances or deliver, in lieu of any shares of Common Stock otherwise deliverable upon conversion in excess of the Conversion Restriction, an amount of cash per share equal to the VWAP per
share of Common Stock on the Trading Day immediately preceding the Conversion Date (such cash amount, the “Excess Amount”). For the avoidance of doubt, when the Stockholder Approval is obtained, this
Section 6(c) shall be deemed deleted in its entirety. 

  
 11 

 SECTION 7. [Reserved]. 

SECTION 8. Conversion Procedures and Effect of Conversion. (a) Conversion Procedure. A Holder must do each of the following
in order to convert shares of Series A Preferred Stock pursuant to this Section 8(a): 
 (i) in the
case of a conversion pursuant to Section 6(a), complete and manually sign the conversion notice provided by the Conversion Agent (the “Conversion Notice”), and deliver such notice to the Conversion Agent;
provided that a Conversion Notice may be conditional on the completion of a Change of Control or other corporate transaction; 

(ii) deliver to the Conversion Agent the certificate or certificates (if any) representing the shares of Series A Preferred
Stock to be converted; 
 (iii) if required, furnish appropriate endorsements and transfer documents; and 

(iv) if required, pay any stock transfer, documentary, stamp or similar taxes not payable by the Company pursuant to
Section 21. 
 The “Conversion Date” means with respect to conversion of any shares of Series A Preferred Stock
at the option of any Holder pursuant to Section 6(a), the date on which such Holder complies with the procedures in this Section 8(a) (including the satisfaction of any conditions to conversion set
forth in the Conversion Notice). 
 (b) Effect of Conversion. Effective immediately prior to the close of business on the Conversion
Date applicable to any shares of Series A Preferred Stock, Participating Dividends shall no longer be declared on any such shares of Series A Preferred Stock, and such shares of Series A Preferred Stock shall cease to be outstanding. 

(c) Record Holder of Underlying Securities as of Conversion Date. The Person or Persons entitled to receive the Common Stock and, to the
extent applicable, cash, securities or other property issuable upon conversion of Series A Preferred Stock on a Conversion Date shall be treated for all purposes as the record holder(s) of such shares of Common Stock and/or cash, securities or other
property as of the close of business on such Conversion Date. As promptly as practicable on or after the Conversion Date and compliance by the applicable Holder with the relevant procedures contained in Section 8(a) (and in
any event no later than three (3) Trading Days thereafter; provided, however, that, if a written notice from the Holder in accordance with Section 8(a) specifies a date of delivery for any shares of
Common Stock, such shares shall be delivered on the date so specified, which shall be no earlier than the second Business Day immediately following the date of such notice and no later than the seventh Business Day thereafter), the Company shall
issue the number of whole shares of Common Stock issuable upon conversion (and deliver payment of cash in lieu of fractional shares as set out in Section 11(h) and any Excess Amount) and, to the extent applicable, any cash,
securities or other property issuable thereon. Such delivery of shares of Common Stock, securities or other property shall be made by book-entry or, at the request of the Holder, through the facilities of The Depositary Trust Company or in
certificated form. Any such certificate or certificates shall be delivered by the Company to the appropriate Holder on a book-entry basis, through the facilities of The Depositary Trust Company, or by mailing certificates evidencing the shares to

  
 12 

 
the Holders, in each case at their respective addresses as set forth in the Conversion Notice (in the case of a conversion pursuant to Section 6(a)). In the event that a
Holder shall not by written notice designate the name in which shares of Common Stock (and payments of cash in lieu of fractional shares) and, to the extent applicable, cash, securities or other property to be delivered upon conversion of shares of
Series A Preferred Stock should be registered or paid, or the manner in which such shares, cash, securities or other property should be delivered, the Company shall be entitled to register and deliver such shares, securities or other property, and
make such payment, in the name of the Holder and in the manner shown on the records of the Company. 
 (d) Status of Converted or
Reacquired Shares. Shares of Series A Preferred Stock converted in accordance with this Certificate of Designations, or otherwise acquired by the Company in any manner whatsoever, shall be retired promptly after the conversion or acquisition
thereof. All such shares shall, upon their retirement and any filing required by the Texas Business Organizations Code, become authorized but unissued shares of Preferred Stock, without designation as to series until such shares are once more
designated as part of a particular series by the Board pursuant to the provisions of the Articles of Incorporation. 
 SECTION 9. Change
of Control. 
 (a) Subject to Section 9(d), upon the occurrence of a Change of Control, the Company shall be
required to redeem the outstanding shares of Series A Preferred Stock at a redemption price per share of Series A Preferred Stock, payable in cash, equal to the greater of (i) the Series A Change of Control Redemption Price of such share of
Series A Preferred Stock and (ii) (A) the amount of cash such Holder would have received plus (B) the Fair Market Value of any other assets in each case had such Holder, immediately prior to such Change of Control, converted such
share of Series A Preferred Stock into Common Stock pursuant to Section 6 without regard to any of the limitations on convertibility contained therein (the “Change of Control Redemption Price”). 

(b) Initial Change of Control Notice. On or before the twentieth (20th) Business Day prior to the date on which the Company anticipates
consummating a Change of Control (or, if later, promptly after the Company discovers that a Change of Control may occur), a written notice (a “Change of Control Notice”) shall be sent by or on behalf of the Company to the Holders as
they appear in the records of the Company, which notice shall contain the date on which the Change of Control is anticipated to be effected (or, if applicable, the date on which a Schedule TO or other schedule, form or report disclosing a Change of
Control was filed). The Change of Control Notice shall include (i) a description of the material terms and conditions of the Change of Control, (ii) the date on which the Change of Control is anticipated to be consummated, (iii) the
Change of Control Redemption Price and the calculation thereof and (iv) the instructions a Holder must follow to receive payment. 
 (c)
Delivery upon Change of Control. Upon the consummation of a Change of Control, subject to Section 9(d), the Company (or its successor) shall deliver or cause to be delivered to the Holder by wire transfer the Change
of Control Redemption Price of such Holder’s shares of Series A Preferred Stock. 

  
 13 

 (d) Sufficient Funds. If the Company shall not have sufficient funds legally
available under the Texas Business Organizations Code to redeem all outstanding shares of Series A Preferred Stock if it redeems outstanding shares of Series A Preferred Stock, the Company shall (i) redeem, pro rata among the Holders, a number
of shares of Series A Preferred Stock with an aggregate Change of Control Redemption Price equal to the amount legally available for the redemption of shares of Series A Preferred Stock under the Texas Business Organizations Code and
(ii) redeem any shares of Series A Preferred Stock not purchased because of the foregoing limitations at the applicable Change of Control Redemption Price as soon as practicable after the Company is able to make such redemption out of assets
legally available for the purchase of such share of Series A Preferred Stock. The inability of the Company (or its successor) to make a redemption payment for any reason shall not relieve the Company (or its successor) from its obligation to effect
any required purchase when, as and if permitted by applicable law. If the Company fails to pay the Change of Control Redemption Price in full when due in accordance with this Section 9 in respect of some or all of the
shares of Series A Preferred Stock to be redeemed pursuant to this Section 9, the Rate of Accretion on such shares repurchased shall equal 10.0% per annum, which shall then increase by 0.50% on every three-month anniversary
after such failure (but not, in any event, to greater than 12.0% per annum. Notwithstanding the foregoing, if a Change of Control occurs at a time when the Company is restricted or prohibited from redeeming some or all of the Series A Preferred
Stock, the Company will use its commercially reasonable efforts to obtain the requisite consents to remove or obtain an exception or waiver to such restrictions or prohibition. Nothing herein shall limit a Holder’s right to pursue any other
remedies available to it hereunder, at law or in equity, including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to comply with its obligations under the
Section 9. 
 (e) Change of Control Agreements. The Company shall not enter into any agreement for a
transaction constituting a Change of Control unless (i) such agreement provides for or does not interfere with or prevent (as applicable) the payment in full of the Change of Control Redemption Price pursuant to this
Section 9 and (ii) the acquiring or surviving Person in such Change of Control represents or covenants, in form and substance reasonably satisfactory to the Board acting in good faith, that at the closing of such
Change of Control, such Person shall have sufficient funds (which may include, without limitation, cash and cash equivalents on the Company’s balance sheet, the proceeds of any debt or equity financing, available lines of credit or uncalled
capital commitments) to consummate such Change of Control and effect the payment of the Change of Control Redemption Price in respect of the outstanding shares of Series A Preferred Stock. 

(f) Partial Redemption. In case any certificate for shares of Series A Preferred Stock shall be surrendered for partial redemption, the
Company shall execute and deliver to or upon the written order of the Holder of the certificate so surrendered a new certificate for the shares of Series A Preferred Stock not redeemed. 

(g) Effect of Redemption. Effective immediately prior to the close of business on the Redemption Date for any shares of Series A
Preferred Stock redeemed pursuant to this Section 9, Participating Dividends shall no longer be declared on any such shares of Series A Preferred Stock, and such shares of Series A Preferred Stock shall cease to be
outstanding. 

  
 14 

 (h) Status of Redeemed Shares. Shares of Series A Preferred Stock redeemed in
accordance with this Section 9, shall return to the status of and constitute authorized but unissued shares of Preferred Stock, without classification as to series until such shares are once more classified as a particular
series by the Board pursuant to the provisions of the Articles of Incorporation. 
 SECTION 10. Optional Redemption. (a) The Series A
Preferred Stock may be redeemed in whole, but not in part, for cash at any time after the fourth anniversary of the Original Issuance Date, at the option of the Company, upon giving notice of redemption pursuant to
Section 10(b), at a redemption price per share equal to the product of (A) the Accreted Value per share of the Series A Preferred Stock to be redeemed as of the applicable Redemption Date multiplied by (B) 1.50.

 (b) Notice of every redemption of shares of Series A Preferred Stock pursuant to Section 10(a)(i) shall be
mailed, postage prepaid, addressed to the Holders of record of the shares to be redeemed at their respective last addresses appearing on the books of the Company, or given by electronic communication in compliance with the provisions of the Texas
Business Organizations Code. Such mailing or electronic transmission shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice made as provided in this Section 10(b) shall be
conclusively presumed to have been duly given upon such mailing or electronic transmission, whether or not the Holder receives such notice, but failure duly to give such notice as provided in this Section 10(b), or any
defect in such notice or in the mailing or electronic transmission thereof, to any Holder of shares of Series A Preferred Stock designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of
Series A Preferred Stock. Each notice of redemption given to a Holder shall state: (1) the redemption date; (2) the number of shares of the Series A Preferred Stock to be redeemed and, if less than all the shares held by such Holder are to
be redeemed, the number of such shares to be redeemed from such Holder; (3) the redemption price; and (4) the place or places where certificates for such shares are to be surrendered for payment of the redemption price. 

SECTION 11. Anti-Dilution Adjustments. (a) Adjustments. The Conversion Rate will be subject to adjustment, without
duplication, upon the occurrence of the following events, except that the Company shall not make any adjustment to the Conversion Rate if Holders of the Series A Preferred Stock participate, at the same time and upon the same terms as holders of
Common Stock and solely as a result of holding shares of Series A Preferred Stock, in any transaction described in this Section 11(a), without having to convert their Series A Preferred Stock, as if they held a number of
shares of Common Stock equal to the product of (x) Accreted Value of the shares of Series A Preferred Stock held by such Holders multiplied by (y) the Conversion Rate divided by (z) 1,000: 

(i) The issuance of Common Stock as a dividend or distribution to all or substantially all holders of Common Stock, or a
subdivision or combination of Common Stock or a reclassification of Common Stock into a greater or lesser number of shares of Common Stock, in which event the Conversion Rate shall be adjusted based on the following formula: 

CR1 = CR0 x (OS1 / OS0) 

  
 15 

 CR0 = the Conversion Rate in effect
immediately prior to the close of business on (i) the Record Date for such dividend or distribution, or (ii) the effective date of such subdivision, combination or reclassification 

CR1 = the new Conversion Rate in effect immediately after the close of business on
(i) the Record Date for such dividend or distribution, or (ii) the effective date of such subdivision, combination or reclassification 

OS0 = the number of shares of Common Stock outstanding immediately prior to the close
of business on (i) the Record Date for such dividend or distribution or (ii) the effective date of such subdivision, combination or reclassification 

OS1 = the number of shares of Common Stock that would be outstanding immediately after,
and solely as a result of, the completion of such event 
 Any adjustment made pursuant to this clause (i) shall be
effective immediately after the close of business on the Record Date for such dividend or distribution, or the effective date of such subdivision, combination or reclassification. If any such event is announced or declared but does not occur, the
Conversion Rate shall be readjusted, effective as of the date the Board announces that such event shall not occur, to the Conversion Rate that would then be in effect if such event had not been declared. 

(ii) The dividend, distribution or other issuance to all or substantially all holders of Common Stock of rights (other than
rights, options or warrants distributed in connection with a stockholder rights plan (in which event the provisions of Section 11(a)(vii) shall apply)), options or warrants entitling them to subscribe for or purchase shares
of Common Stock for a period expiring forty-five (45) days or less from the date of issuance thereof, at a price per share that is less than the Current Market Price as of the Record Date for such issuance, in which event the Conversion Rate
will be increased based on the following formula: 

                    CR1 = CR0 x [(OS0+X) / (OS0+Y)]

 CR0 = the Conversion Rate in effect immediately prior to the close of business on
the Record Date for such dividend, distribution or issuance 
 CR1 = the new
Conversion Rate in effect immediately following the close of business on the Record Date for such dividend, distribution or issuance 
 OS0 = the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such dividend, distribution or issuance 

X = the total number of shares of Common Stock issuable pursuant to such rights, options or warrants 

Y = the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the
Current Market Price as of the Record Date for such dividend, distribution or issuance. 

  
 16 

 For purposes of this clause (ii), in determining whether any rights, options
or warrants entitle the holders to purchase the Common Stock at a price per share that is less than the Current Market Price as of the Record Date for such dividend, distribution or issuance, there shall be taken into account any consideration the
Company receives for such rights, options or warrants, and any amount payable on exercise thereof, with the value of such consideration, if other than cash, to be the Fair Market Value thereof. 

Any adjustment made pursuant to this clause (ii) shall become effective immediately following the close of business on the
Record Date for such dividend, distribution or issuance. In the event that such rights, options or warrants are not so issued, the Conversion Rate shall be readjusted, effective as of the date the Board publicly announces its decision not to issue
such rights, options or warrants, to the Conversion Rate that would then be in effect if such dividend, distribution or issuance had not been declared. To the extent that such rights, options or warrants are not exercised prior to their expiration
or shares of Common Stock are otherwise not delivered pursuant to such rights, options or warrants upon the exercise of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had
the adjustments made upon the dividend, distribution or issuance of such rights, options or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. 

(iii) The Company or one or more of its Subsidiaries purchases Common Stock pursuant to a tender offer or exchange offer (other
than an exchange offer that constitutes a Distribution Transaction subject to Section 11(a)(v)) by the Company or a Subsidiary of the Company for all or any portion of the Common Stock, or otherwise acquires Common Stock
(except (1) in an open market purchase in compliance with Rule 10b-18 promulgated under the Exchange Act, (2) through an “accelerated share repurchase” on customary terms or (3) in
connection with tax withholding upon vesting or settlement of options, restricted stock units, performance share units or other similar equity awards or upon forfeiture or cashless exercise of options or other equity awards) (a “Covered
Repurchase”), if the cash and value of any other consideration included in the payment per share of Common Stock validly tendered, exchanged or otherwise acquired through a Covered Repurchase exceeds the arithmetic average of the VWAP per
share of Common Stock for each of the ten (10) consecutive full Trading Days commencing on, and including, the Trading Day next succeeding the last day on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it
may be amended) or shares of Common Stock are otherwise acquired through a Covered Repurchase (the “Expiration Date”), in which event the Conversion Rate shall be increased based on the following formula: 

CR1 = CR0 x [(FMV + (SP1 x OS1))] / (SP1 x OS0) 

CR0 = the Conversion Rate in effect immediately prior to the close of business on the
Expiration Date 
 CR1 = the new Conversion Rate in effect immediately after the
close of business on the Expiration Date 

  
 17 

 FMV = the Fair Market Value, on the Expiration Date, of all cash and any other consideration
paid or payable for all shares validly tendered or exchanged and not withdrawn, or otherwise acquired through a Covered Repurchase, as of the Expiration Date 

OS0 = the number of shares of Common Stock outstanding immediately prior to the last
time tenders or exchanges may be made pursuant to such tender or exchange offer (including the shares to be purchased in such tender or exchange offer) or shares are otherwise acquired through a Covered Repurchase 

OS1 = the number of shares of Common Stock outstanding immediately after the last time
tenders or exchanges may be made pursuant to such tender or exchange offer (after giving effect to the purchase of shares in such tender or exchange offer) or shares are otherwise acquired through a Covered Repurchase 

SP1 = the arithmetic average of the VWAP per share of Common Stock for each of the ten
(10) consecutive full Trading Days commencing on, and including, the Trading Day next succeeding the Expiration Date 

Such adjustment shall become effective immediately after the close of business on the Expiration Date. If an adjustment to the
Conversion Rate is required under this Section 11(a)(iii), delivery of any additional shares of Common Stock that may be deliverable upon conversion as a result of an adjustment required under this
Section 11(a)(iii) shall be delayed to the extent necessary in order to complete the calculations provided for in this Section 11(a)(iii). 

In the event that the Company or any of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender
offer, exchange offer or other commitment to acquire shares of Common Stock through a Covered Repurchase but is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Rate
shall be readjusted to be the Conversion Rate that would have been then in effect if such tender offer, exchange offer or Covered Repurchase had not been made. 

(iv) The Company shall, by dividend or otherwise, distribute to all or substantially all holders of its Common Stock (other
than for cash in lieu of fractional shares), shares of any class of its Capital Stock, evidences of its Indebtedness, assets, other property or securities, but excluding (A) dividends or distributions referred to in
Section 11(a)(i) or Section 11(a)(ii) hereof, (B) Distribution Transactions as to which Section 11(a)(v) shall apply, (C) dividends or
distributions paid exclusively in cash as to which Section 11(a)(vi) shall apply and (D) rights, options or warrants distributed in connection with a stockholder rights plan as to which
Section 11(a)(vii) shall apply (any of such shares of its Capital Stock, Indebtedness, assets or property that are not so excluded are hereinafter called the “Distributed Property”), then, in each such case
the Conversion Rate shall be increased based on the following formula: 
 CR1 = CR0 x [SP0 / (SP0 - FMV)] 

  
 18 

 CR0 = the Conversion Rate in effect
immediately prior to the close of business on the Record Date for such dividend or distribution 
 CR1 = the new Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution 

SP0 = the Current Market Price as of the Record Date for such dividend or distribution

 FMV = the Fair Market Value of the portion of Distributed Property distributed with respect to each outstanding share of Common Stock on
the Record Date for such dividend or distribution; provided that, if FMV is equal or greater than SP0, then in lieu of the foregoing adjustment, the Company shall distribute to each
holder of Series A Preferred Stock on the date the applicable Distributed Property is distributed to holders of Common Stock, but without requiring such holder to convert its shares of Series A Preferred Stock, in respect of each share of Series A
Preferred Stock held by such holder, the amount of Distributed Property such holder would have received had such holder owned a number of shares of Common Stock equal to the Conversion Rate on the Record Date for such dividend or distribution 

Any adjustment made pursuant to this clause (iv) shall be effective immediately after the close of business on the Record
Date for such dividend or distribution. If any such dividend or distribution is declared but does not occur, the Conversion Rate shall be readjusted, effective as of the date the Board announces that such dividend or distribution shall not occur, to
the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (v) The Company
effects a Distribution Transaction, in which case the Conversion Rate in effect immediately prior to the effective date of the Distribution Transaction shall be increased based on the following formula: 

CR1 = CR0 x [(FMV + MP0) / MP0] 
 CR0 = the Conversion Rate in effect immediately prior to the close of business on the effective date of the Distribution Transaction 

CR1 = the new Conversion Rate in effect immediately after the close of business on the
effective date of the Distribution Transaction 
 FMV = the arithmetic average of the volume-weighted average prices for a share of the
capital stock or other interest distributed to holders of Common Stock on the principal United States securities exchange or automated quotation system on which such capital stock or other interest trades, as reported by Bloomberg (or, if Bloomberg
ceases to publish such price, any successor service chosen by the Company) in respect of the period from the open of trading on the relevant Trading Day until the close of trading on such Trading Day (or if such volume-weighted average price is
unavailable, the market price of one share of such capital stock or other interest on such Trading Day determined, using a volume-weighted average method, by an Independent Financial Advisor retained for such purpose by the Company), for each of the
ten consecutive full Trading Days commencing with, and including, the effective date of the Distribution Transaction 

  
 19 

 MP0 = the arithmetic average of the
VWAP per share of Common Stock for each of the ten (10) consecutive full Trading Days commencing on, and including, the effective date of the Distribution Transaction 

Such adjustment shall become effective immediately following the close of business on the effective date of the Distribution
Transaction. If an adjustment to the Conversion Rate is required under this Section 11(a)(v), delivery of any additional shares of Common Stock that may be deliverable upon conversion as a result of an adjustment required
under this Section 11(a)(v) shall be delayed to the extent necessary in order to complete the calculations provided for in this Section 11(a)(v). 

(vi) The Company makes a cash dividend or distribution to all or substantially all holders of the Common Stock, the Conversion
Rate shall be increased based on the following formula: 
 CR1 = CR0 x [SP0 / (SP0 – C)] 

CR0 = the Conversion Rate in effect immediately prior to the close of business on the
Record Date for such dividend or distribution 
 CR1 = the new Conversion Rate in
effect immediately after the close of business on the Record Date for such dividend or distribution 
 SP0 = the Current Market Price as of the Record Date for such dividend or distribution

= the amount in cash per share of Common Stock the Company distributes to all or substantially all holders of its Common Stock; provided that, if C is equal or greater than SP0, then in
lieu of the foregoing adjustment, the Company shall pay to each holder of Series A Preferred Stock on the date the applicable cash dividend or distribution is made to holders of Common Stock, but without requiring such holder to convert its shares
of Series A Preferred Stock, in respect of each share of Series A Preferred Stock held by such holder, the amount of cash such holder would have received had such holder owned a number of shares of Common Stock equal to the Conversion Rate on the
Record Date for such dividend or distribution 
 Any adjustment made pursuant to this clause (vi) shall be effective
immediately after the close of business on the Record Date for such dividend or distribution. If any dividend or distribution is declared but not paid, the Conversion Rate shall be readjusted, effective as of the date the Board announces that such
dividend or distribution will not be paid, to the Conversion Rate that would then be in effect if such had dividend or distribution not been declared. 

(vii) If the Company has a stockholder rights plan in effect with respect to the Common Stock on any Conversion Date, upon
conversion of any shares of the Series A Preferred Stock, Holders of such shares will receive, in addition to the applicable number of shares of Common Stock, the rights under such rights plan relating to such Common Stock, unless, prior to such
Conversion Date, the rights have (i) become exercisable or (ii) separated from the shares of Common Stock (the first of such events to occur, a 

  
 20 

 
“Trigger Event”), in which case, the Conversion Rate will be adjusted, effective automatically at the time of such Trigger Event, as if the Company had made a distribution of
such rights to all holders of the Company Common Stock as described in Section 11(a)(ii) (without giving effect to the forty-five (45) day limit on the exercisability of rights, options or warrants ordinarily subject
to such Section 11(a)(ii)), subject to appropriate readjustment in the event of the expiration, termination or redemption of such rights prior to the exercise, deemed exercise or exchange thereof. Notwithstanding the
foregoing, to the extent any such stockholder rights are exchanged by the Company for shares of Common Stock or other property or securities, the Conversion Rate shall be appropriately readjusted as if such stockholder rights had not been issued,
but the Company had instead issued such shares of Common Stock or other property or securities as a dividend or distribution of shares of Common Stock pursuant to Section 11(a)(i) or
Section 11(a)(iv), as applicable. 
 To the extent that such rights are not exercised prior to their
expiration, termination or redemption, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the occurrence of the Trigger Event been made on the basis of the issuance of, and the
receipt of the exercise price with respect to, only the number of shares of Common Stock actually issued pursuant to such rights. 

Notwithstanding anything to the contrary in this Section 11(a)(vii), no adjustment shall be required
to be made to the Conversion Rate with respect to any Holder which is, or is an “affiliate” or “associate” of, an “acquiring person” under such stockholder rights plan or with respect to any direct or indirect
transferee of such Holder who receives Series A Preferred Stock in such transfer after the time such Holder becomes, or its affiliate or associate becomes, such an “acquiring person”. 

(b) Calculation of Adjustments. All adjustments to the Conversion Rate shall be calculated by the Company to the nearest 1/10,000th of
one share of Common Stock (or if there is not a nearest 1/10,000th of a share, to the next lower 1/10,000th of a share). No adjustment to the Conversion Rate will be required unless such adjustment would require an increase or decrease of at least
one percent of the Conversion Rate; provided, however, that any such adjustment that is not required to be made will be carried forward and taken into account in any subsequent adjustment; provided, further, that any such
adjustment of less than one percent that has not been made will be made upon any Conversion Date or redemption or repurchase date. 
 (c)
When No Adjustment Required. (i) Except as otherwise provided in this Section 11, the Conversion Rate will not be adjusted for the issuance of Common Stock or any securities convertible into or exchangeable for
Common Stock or carrying the right to purchase any of the foregoing, for the repurchase of Common Stock or to the extent that an adjustment would be duplicative because an equivalent Participating Dividend was distributed to the Holders. 

(ii) Except as otherwise provided in this Section 11, the Conversion Rate will not be adjusted as a
result of the issuance of, the distribution of separate certificates representing, the exercise or redemption of, or the termination or invalidation of, rights pursuant to any stockholder rights plans. 

  
 21 

 (iii) No adjustment to the Conversion Rate will be made: 

(A) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of
dividends or interest payable on securities of the Company and the investment of additional optional amounts in Common Stock under any plan in which purchases are made at market prices on the date or dates of purchase, without discount, and whether
or not the Company bears the ordinary costs of administration and operation of the plan, including brokerage commissions; 

(B) upon the issuance of any shares of Common Stock or options or rights to purchase such shares pursuant to any present or
future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries or of any employee agreements or arrangements or programs; 

(C) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or
convertible security, including the Series A Preferred Stock; or 
 (D) for a change in the par value of the Common Stock.

 (d) Successive Adjustments. After an adjustment to the Conversion Rate under this Section 11, any
subsequent event requiring an adjustment under this Section 11 shall cause an adjustment to each such Conversion Rate as so adjusted. 

(e) Multiple Adjustments. For the avoidance of doubt, if an event occurs that would trigger an adjustment to the Conversion Rate
pursuant to this Section 11 under more than one subsection hereof, such event, to the extent fully taken into account in a single adjustment, shall not result in multiple adjustments hereunder; provided,
however, that if more than one subsection of this Section 11 is applicable to a single event, the subsection shall be applied that produces the largest adjustment. 

(f) Notice of Adjustments. Whenever the Conversion Rate is adjusted as provided under this Section 11, the
Company shall as soon as reasonably practicable following the occurrence of an event that requires such adjustment (or if the Company is not aware of such occurrence, as soon as reasonably practicable after becoming so aware): 

(i) compute the adjusted applicable Conversion Rate in accordance with this Section 11 and prepare
and transmit to the Conversion Agent an Officer’s Certificate setting forth the applicable Conversion Rate, the method of calculation thereof, and the facts requiring such adjustment and upon which such adjustment is based; and 

(ii) provide a written notice to the Holders of the occurrence of such event and a statement in reasonable detail setting forth
the method by which the adjustment to the applicable Conversion Rate was determined and setting forth the adjusted applicable Conversion Rate. 

  
 22 

 (g) Conversion Agent. The Conversion Agent shall not at any time be under any duty or
responsibility to any Holder to determine whether any facts exist that may require any adjustment of the Conversion Rate or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed
in making the same. The Conversion Agent shall be fully authorized and protected in relying on any Officer’s Certificate delivered pursuant to this Section 11(g) and any adjustment contained therein and the Conversion
Agent shall not be deemed to have knowledge of any adjustment unless and until it has received such certificate. The Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common
Stock, or of any securities or property, that may at the time be issued or delivered with respect to any Series A Preferred Stock and the Conversion Agent makes no representation with respect thereto. The Conversion Agent shall not be responsible
for any failure of the Company to issue, transfer or deliver any shares of Common Stock pursuant to the conversion of Series A Preferred Stock or to comply with any of the duties, responsibilities or covenants of the Company contained in this
Section 11. 
 (h) Fractional Shares. No fractional shares of Common Stock will be delivered to the Holders upon
conversion. In lieu of fractional shares otherwise issuable, the Holders will be entitled to receive, at the Company’s sole discretion, either (i) an amount in cash equal to the fraction of a share of Common Stock multiplied by the Closing
Price of the Common Stock on the Trading Day immediately preceding the applicable Conversion Date or (ii) one additional whole share of Common Stock. In order to determine whether the number of shares of Common Stock to be delivered to a Holder
upon the conversion of such Holder’s shares of Series A Preferred Stock will include a fractional share, such determination shall be based on the aggregate number of shares of Series A Preferred Stock of such Holder that are being converted on
any single Conversion Date. 
 SECTION 12. Adjustment for Reorganization Events. 

(a) Reorganization Events. In the event of: 

(i) any reclassification, statutory exchange, merger, consolidation or other similar business combination of the Company with
or into another Person, in each case, pursuant to which at least a majority of the Common Stock is changed or converted into, or exchanged for, cash, securities or other property of the Company or another Person; 

(ii) any sale, transfer, lease or conveyance to another Person of all or a majority of the property and assets of the Company,
in each case pursuant to which the Common Stock is converted into cash, securities or other property; or 
 (iii) any
statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition) or reclassification, recapitalization or reorganization of the Common Stock into other securities; 

  
 23 

 (each of which is referred to as a “Reorganization Event”), each share of Series A
Preferred Stock outstanding immediately prior to such Reorganization Event will, without the consent of the Holders and subject to Section 12(d) and Section 13(b), remain outstanding but shall
become convertible into, out of funds legally available therefor, the number, kind and amount of securities, cash and other property (the “Exchange Property”) (without any interest on such Exchange Property and without any right to
dividends or distribution on such Exchange Property which have a record date that is prior to the applicable Conversion Date) that the Holder of such share of Series A Preferred Stock would have received in such Reorganization Event had such Holder
converted its shares of Series A Preferred Stock into the applicable number of shares of Common Stock immediately prior to the effective date of the Reorganization Event using the Conversion Rate applicable immediately prior to the effective date of
the Reorganization Event and the Accreted Value applicable at the time of such subsequent conversion; provided that the foregoing shall not apply if such Holder is a Person with which the Company consolidated or into which the Company merged
or which merged into the Company or to which such sale or transfer was made, as the case may be (any such Person, a “Constituent Person”), or an Affiliate of a Constituent Person, to the extent such Reorganization Event provides for
different treatment of Common Stock held by such Constituent Persons or such Affiliate thereof. If the kind or amount of securities, cash and other property receivable upon such Reorganization Event is not the same for each share of Common Stock
held immediately prior to such Reorganization Event by a Person (other than a Constituent Person or an Affiliate thereof), then for the purpose of this Section 12(a), the kind and amount of securities, cash and other
property receivable upon conversion following such Reorganization Event will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock. 

(b) Successive Reorganization Events. The above provisions of this Section 12 shall similarly apply to
successive Reorganization Events and the provisions of Section 11 shall apply to any shares of Capital Stock received by the holders of the Common Stock in any such Reorganization Event. 

(c) Reorganization Event Notice. The Company (or any successor) shall, no less than thirty (30) days prior to the anticipated
effective date of any Reorganization Event, provide written notice to the Holders of such occurrence of such event and of the kind and amount of the cash, securities or other property that constitutes the Exchange Property. Failure to deliver such
notice shall not affect the operation of this Section 12. 
 (d) Reorganization Event Agreements. The
Company shall not enter into any agreement for a transaction constituting a Reorganization Event unless (i) such agreement provides for or does not interfere with or prevent (as applicable) conversion of the Series A Preferred Stock into the
Exchange Property in a manner that is consistent with and gives effect to this Section 12, and (ii) to the extent that the Company is not the surviving corporation in such Reorganization Event or will be dissolved in
connection with such Reorganization Event, proper provision shall be made in the agreements governing such Reorganization Event for the conversion of the Series A Preferred Stock into stock of the Person surviving such Reorganization Event or such
other continuing entity in such Reorganization Event. 

  
 24 

 SECTION 13. Voting Rights. 

(a) General. Except as provided in Section 13(b) and Section 14, Holders of shares
of Series A Preferred Stock shall be entitled to vote as a single class with the holders of the Common Stock and the holders of any other class or series of Capital Stock of the Company then entitled to vote with the Common Stock on all matters
submitted to a vote of the holders of Common Stock (and, if applicable, holders of any other class or series of Capital Stock of the Company). Each Holder shall be entitled to the number of votes equal to the product of (i) the largest number
of whole shares of Common Stock into which all shares of Series A Preferred Stock could be converted pursuant to Section 6 (taking into account the Conversion Restriction to the extent applicable) multiplied by
(ii) a fraction the numerator of which is the number of shares of Series A Preferred Stock held by such Holder and the denominator of which is the aggregate number of issued and outstanding shares of Series A Preferred Stock, in each case at
and calculated as of the record date for the determination of stockholders entitled to vote or consent on such matters or, if no such record date is established, at and as of the date such vote or consent is taken or any written consent of
stockholders is first executed. The Holders shall be entitled to notice of any meeting of holders of Common Stock in accordance with the Articles of Incorporation and Bylaws of the Company. 

(b) Consent Rights. The vote or consent of the Holders of at least a majority of the shares of Series A Preferred Stock outstanding at
such time, voting together as a separate class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary for effecting or validating any of the following actions, whether or
not such approval is required pursuant to the Texas Business Organizations Code: 
 (i) any amendment, alteration or repeal
(whether by merger, consolidation or otherwise) of any provision of the Articles of Incorporation (including this Certificate of Designations) or Bylaws that would have an adverse effect on the rights, preferences, privileges or voting power of the
Series A Preferred Stock or the Holder thereof; 
 (ii) any amendment or alteration (whether by merger, consolidation or
otherwise) of, or any supplement (whether by a certificate of designations or otherwise) to, the Articles of Incorporation or any provision thereof, or any other action to authorize or create, or increase the number of authorized or issued shares
of, or any securities convertible into shares of, or reclassify any security into, or issue, any Parity Stock or Senior Stock or any other class or series of Capital Stock of the Company ranking senior to, or on a parity basis with, the Series A
Preferred Stock as to dividend rights or rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company; 

(iii) any issuance of shares of Series A Preferred Stock after the Original Issuance Date other than in connection with the
conversion of Series B Preferred Stock that was issued on the Original Issuance Date; 
 (iv) any action that would cause the
Company to cease to be treated as a domestic C corporation for U.S. federal income tax purposes; 
 (v) on or prior to the
Business Day immediately following the Stockholder Meeting, effect any action that would result in (A) a change to the Conversion Rate, (B) the obligation to pay Participating Dividends or (C) the payment of cash dividends in respect
of the Series B Preferred Stock; and 

  
 25 

 (vi) any incurrence of any Indebtedness of the Company or any of its
Subsidiaries (other than (x) the refinancing of any existing Indebtedness in an aggregate principal amount that does not exceed the then outstanding principal amount of the Indebtedness refinanced, plus all unpaid accrued or capitalized
interest thereon, any prepayment premium applicable thereto, any swap breakage costs or hedge termination costs related thereto, upfront fees and original issue discount on such refinancing indebtedness, and customary fees and expenses relating to
such financing, and (y) ordinary course of business working capital draws under the Company’s revolving credit facility) to the extent that, immediately after giving effect to such incurrence or refinancing, the ratio of the consolidated
Indebtedness of the Company and its Subsidiaries (net of unrestricted cash and cash equivalents of the Company and its Subsidiaries) to the EBITDA of the Company and its Subsidiaries for the most recently ended four fiscal quarters for which
internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred would not be less than a ratio of 5.15-to-1
on a pro forma basis after giving effect to such incurrence and the use of the proceeds therefrom; 
 provided, however, (A) that, with
respect to the occurrence of any of the events set forth in clause (i) above, so long as (1) the Series A Preferred Stock remains outstanding with the terms thereof materially unchanged, or (2) the holders of the Series A Preferred
Stock receive equity securities with rights, preferences, privileges and voting power substantially the same as those of the Series A Preferred Stock, then the occurrence of such event shall not be deemed to adversely affect such rights,
preferences, privileges or voting power of the Series A Preferred Stock, and in such case such holders shall not have any voting rights with respect to the occurrence of any of the events set forth in clause (i) above and (B) that the
authorization or creation of, or the increase in the number of authorized or issued shares of, or any securities convertible into shares of, or the reclassification of any security (other than the Series A Preferred Stock) into, or the issuance of,
Junior Stock will not require the vote the holders of the Series A Preferred Stock. 
 For purposes of this
Section 13, the filing in accordance with applicable law of a certificate of designations or any similar document setting forth or changing the designations, powers, preferences, rights, qualifications, limitations and
restrictions of any class or series of stock of the Company shall be deemed an amendment to the Articles of Incorporation. 
 (c) Each
Holder of Series A Preferred Stock will have one vote per share of Series A Preferred Stock on any matter on which Holders of Series A Preferred Stock are entitled to vote separately as a class, whether at a meeting or by written consent. 

(d) The vote or consent of the Holders of a majority of the shares of Series A Preferred Stock outstanding at such time, voting together as a
single class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be sufficient to waive or amend the provisions of Section 9(e) of this Certificate of
Designations, and any amendment or waiver of any of the provisions of Section 9(e) approved by such percentage of the Holders shall be binding on all of the Holders. 

  
 26 

 (e) For the avoidance of doubt and notwithstanding anything to the contrary in the Articles
of Incorporation or Bylaws of the Company, the Holders of Series A Preferred Stock shall have the exclusive consent and voting rights set forth in Sections 13(b) and 14 and may take action or consent to any action with respect to such
rights without a meeting by delivering a consent in writing or by electronic transmission of the Holders of the Series A Preferred Stock entitled to cast not less than the minimum number of votes that would be necessary to authorize, take or consent
to such action at a meeting of stockholders. 
 SECTION 14. Election of Directors. Provided that the Fall Away of Investor Board
Rights has not occurred and subject to Section 5.10(b) of the Investment Agreement, (i) the Holders of a majority of the then outstanding shares of Series A Preferred Stock shall have, at each annual meeting of the Company’s
stockholders at which the Board is obligated to nominate one or more Investor Designees for election to the Board pursuant to and in accordance with the Investment Agreement, the exclusive right, voting separately as a class, to elect or appoint
such Investor Designee(s) to the Board, irrespective of whether the Board has nominated such Investor Designee(s), (ii) notwithstanding anything to the contrary in the Articles of Incorporation or Bylaws, the Holders of a majority of the then
outstanding shares of Series A Preferred Stock shall have the exclusive right to remove any Investor Designee(s) at any time for any reason or no reason (with or without cause) by sending a written notice to the Company and, upon receipt of such
notice by the Company, such Investor Designee(s) shall be deemed to have resigned from the Board, and (iii) in the event of the death, disability, resignation or removal of any Investor Designee(s), the Investor Parties shall have the exclusive
right to designate or appoint a successor to fill the vacancy created thereby. The Board and the holders of Common Stock shall not have the right to remove any Investor Designee from the Board (even for cause), such right of removal being vested
exclusively with the Holders of a majority of the then outstanding shares of Series A Preferred Stock. 
 SECTION 15. Preemptive
Rights. Except for the right to participate in any issuance of new equity securities by the Company, as set forth in the Investment Agreement, the Holders shall not have any preemptive rights. 

SECTION 16. Term. Except as expressly provided in this Certificate of Designations, the shares of Series A Preferred Stock shall not be
redeemable or otherwise mature and the term of the Series A Preferred Stock shall be perpetual. 
 SECTION 17. Creation of Capital
Stock. Subject to Section 13(b)(ii), the Board, or any duly authorized committee thereof, without the vote of the Holders, may authorize and issue additional shares of Capital Stock of the Company. 

SECTION 18. No Sinking Fund. Shares of Series A Preferred Stock shall not be subject to or entitled to the operation of a retirement or
sinking fund. 
 SECTION 19. Transfer Agent, Conversion Agent, Registrar and Paying Agent. The duly appointed Transfer Agent,
Conversion Agent, Registrar and paying agent for the Series A Preferred Stock shall be Computershare Trust Company, N.A. The Company may, in its sole discretion, appoint any other Person to serve as Transfer Agent, Conversion Agent, Registrar or
paying agent for the Series A Preferred Stock and thereafter may remove or replace such other Person at any time. Upon any such appointment or removal, the Company shall send notice thereof by first class mail, postage prepaid, to the Holders. 

  
 27 

 SECTION 20. Replacement Certificates. (a) Mutilated, Destroyed, Stolen and
Lost Certificates. If physical certificates evidencing the Series A Preferred Stock are issued, the Company shall replace any mutilated certificate at the Holder’s expense upon surrender of that certificate to the Transfer Agent. The
Company shall replace certificates that become destroyed, stolen or lost at the Holder’s expense upon delivery to the Company and the Transfer Agent of satisfactory evidence that the certificate has been destroyed, stolen or lost, together with
any indemnity that may be required by the Transfer Agent and the Company. 
 (b) Certificates Following Conversion. If physical
certificates representing the Series A Preferred Stock are issued, the Company shall not be required to issue replacement certificates representing shares of Series A Preferred Stock on or after the Conversion Date applicable to such shares. In
place of the delivery of a replacement certificate following the applicable Conversion Date, the Transfer Agent, upon receipt of the satisfactory evidence and indemnity described in clause (a) above, shall deliver the shares of Common Stock
issuable upon conversion of such shares of Series A Preferred Stock formerly evidenced by the physical certificate. 
 SECTION 21.
Taxes. (a) Transfer Taxes. The Company shall pay any and all stock transfer, documentary, stamp and similar taxes that may be payable in respect of any issuance or delivery of shares of Series A Preferred Stock or shares of Common
Stock or other securities issued on account of Series A Preferred Stock pursuant hereto or certificates representing such shares or securities. However, in the case of conversion of Series A Preferred Stock, the Company shall not be required to pay
any such tax that may be payable in respect of any transfer involved in the issuance or delivery of shares of Series A Preferred Stock, shares of Common Stock or other securities to a beneficial owner other than the beneficial owner of the Series A
Preferred Stock immediately prior to such conversion, and shall not be required to make any such issuance, delivery or payment unless and until the Person otherwise entitled to such issuance, delivery or payment has paid to the Company the amount of
any such tax or has established, to the satisfaction of the Company, that such tax has been paid or is not payable. 
 (b)
Withholding. All payments and distributions (or deemed distributions) on the shares of Series A Preferred Stock (and on the shares of Common Stock received upon their conversion) shall be subject to withholding and backup withholding of taxes
to the extent required by law, subject to applicable exemptions, and amounts withheld, if any, shall be treated as received by the Holders. 

SECTION 22. Notices. All notices referred to herein shall be in writing and, unless otherwise specified herein, all notices hereunder
shall be deemed to have been given (a) upon the earlier of receipt thereof or three (3) Business Days after the mailing thereof if sent by registered or certified mail with postage prepaid, or by private courier service addressed:
(i) if to the Company, to its office at Zix Corporation, 2711 N. Haskell Avenue, Suite 2200, LB 36, Dallas, Texas 75204-2960 (Attention: General Counsel), (ii) if to any Holder, to such Holder at the address of such Holder as listed in the
stock record books of the Company (which may include the records of the Transfer Agent) or (iii) to such other address as the Company or any such Holder, as the case may be, shall have designated by notice similarly given; or (b) on the
date sent by facsimile or transmitted to an email address designated by the Company or any such Holder if sent during normal business hours, and on the next Business Day if sent after normal business hours of the recipient. 

  
 28 

 SECTION 23. Facts Ascertainable. When the terms of this Certificate of Designations
refers to a specific agreement or other document to determine the meaning or operation of a provision hereof, the Secretary of the Company shall maintain a copy of such agreement or document at the principal executive offices of the Company and a
copy thereof shall be provided free of charge to any Holder who makes a request therefor. The Secretary of the Company shall also maintain a written record of the Issuance Date, the number of shares of Series A Preferred Stock issued to a Holder and
the date of each such issuance, and shall furnish such written record free of charge to any Holder who makes a request therefor. 
 SECTION
24. Waiver. Notwithstanding any provision in this Certificate of Designations to the contrary, any provision contained herein and any right of the Holders of Series A Preferred Stock granted hereunder may be waived as to all shares of Series
A Preferred Stock (and the Holders thereof) upon the vote or written consent of the Holders of a majority of the shares of Series A Preferred Stock then outstanding. 

SECTION 25. Severability. If any term of the Series A Preferred Stock set forth herein is invalid, unlawful or incapable of being
enforced by reason of any rule of law or public policy, all other terms set forth herein which can be given effect without the invalid, unlawful or unenforceable term will, nevertheless, remain in full force and effect, and no term herein set forth
will be deemed dependent upon any other such term unless so expressed herein. 
 SECTION 26. Business Opportunities. To the fullest
extent permitted by Section 2.101(21) of the Texas Business Organizations Code (or any successor provision) and except as may be otherwise expressly agreed in writing by the Company and the Investor Parties, the Company, on behalf of itself and
its Subsidiaries, renounces any interest or expectancy of the Company and its Subsidiaries in, or in being offered an opportunity to participate in, business opportunities, that are from time to time presented to the Investor Parties or any of their
respective officers, representatives, directors, agents, stockholders, members, partners, Affiliates, Subsidiaries (other than the Company and its Subsidiaries), or any of their respective designees on the Company’s Board and/or any of their
respective representatives who, from time to time, may act as officers of the Company, even if the opportunity is one that the Company or its Subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted
the opportunity to do so, and no such person shall be liable to the Company or any of its Subsidiaries for breach of any fiduciary or other duty, as a director or officer or otherwise, by reason of the fact that such person pursues or acquires such
business opportunity, directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Company or its Subsidiaries unless, in the case of any such person
who is a director or officer of the Company, such business opportunity is expressly offered to such director or officer in writing solely in his or her capacity as a director or officer of the Company. Any Person purchasing or otherwise acquiring
any interest in any shares of Capital Stock of the Company shall be deemed to have notice of and consented to the provisions of this Section 26. Neither the alteration, amendment or repeal of this
Section 26, nor the adoption of any provision of the Articles of Incorporation or this Certificate of Designations inconsistent with this Section 26, nor, to the fullest extent permitted by Texas

  
 29 

 
law, any modification of law, shall eliminate or reduce the effect of this Section 26 in respect of any business opportunity first identified or any other matter
occurring, or any cause of action, suit or claim that, but for this Section 26, would accrue or arise, prior to such alteration, amendment, repeal, adoption or modification. If any provision or provisions of this
Section 26 shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (a) the validity, legality and enforceability of such provisions in any other circumstance and
of the remaining provisions of this Section 26 (including, without limitation, each portion of any paragraph of this Section 26 containing any such provision held to be invalid, illegal or
unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (b) to the fullest extent possible, the provisions of this Section 26 (including,
without limitation, each such portion of any paragraph of this Section 26 containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Company to protect its directors,
officers, employees and agents from personal liability in respect of their good faith service to or for the benefit of the Company to the fullest extent permitted by law. This Section 26 shall not limit any protections or
defenses available to, or indemnification or advancement rights of, any director, officer, employee or agent of the Company under the Articles of Incorporation, the Bylaws, any other agreement between the Company and such director, officer, employee
or agent or applicable law.

ZIX CORPORATION 
 ZIX
CORPORATION, a corporation organized and existing under the Business Organizations Code of the State of Texas (the “Company”), in accordance with the provisions of Sections 21.155 and 21.156 thereof: 

HEREBY CERTIFIES: 
 That, the
Restated Articles of Incorporation (the “Articles of Incorporation”) of the Company, as filed with the Secretary of State of the State of Texas, authorizes the issuance of 185,000,000 shares of capital stock, consisting of
175,000,000 shares of common stock, $0.01 par value (“Common Stock”), and 10,000,000 shares of preferred stock, $1.00 par value (“Preferred Stock”); 

That, the Articles of Incorporation expressly authorize the Board of Directors of the Company (the “Board”) by resolution or
resolutions, subject to limitations prescribed by law and by Article IV of the Articles of Incorporation, to provide for the issuance of Preferred Stock as a class or in one or more series and, with respect to each series of Preferred Stock, to
establish the number of shares included in each such series and to fix the designations, powers, relative rights, qualifications, preferences, limitations and restrictions of the shares of such series not fixed by the Articles of Incorporation; 

That, pursuant to the authority conferred upon the Board by the Articles of Incorporation, the Board, on [•], 2019, adopted the following
resolution designating a new series of Preferred Stock as “Series B Convertible Preferred Stock”: 
 RESOLVED, that, pursuant to
the authority vested in the Board in accordance with the provisions of Article IV of the Articles of Incorporation and the provisions of Section 21.155 of the Texas Business Organizations Code, a series of Preferred Stock of the Company is
hereby authorized, and the number of shares to be included in such series, and the designations, powers, relative rights, qualifications, preferences, limitations and restrictions of the shares of Preferred Stock included in such series, shall be as
follows:

the “Redemption Price”), payable in cash. 
 (i) To exercise its Holder Redemption Right pursuant to this
Section 10(b) in respect of any Designated Redemption Date, a Holder must, no later than 5:00 p.m., New York City time, on the date that is at least 90 days prior to the Designated Redemption Date specified by the Holder
therein, deliver written notice thereof (a “Notice of Holder Redemption”) to the Company and the Transfer Agent and shall, on or prior to the Designated Redemption Date, surrender to the Transfer Agent the certificates representing
the shares of Series B Preferred Stock to be redeemed by the Company; provided that, such Holder will be entitled to revoke its Notice of Holder Redemption at any time but no later than 15 days prior to the Designated Redemption Date. On such
Designated Redemption Date, the Company shall deliver or cause to be delivered to each Holder that has exercised its Holder Redemption Right with respect to such Designated Redemption Date, cash by wire transfer, the Redemption Price of the shares
of Series B Preferred Stock in respect of which such Holder has delivered (and has not revoked in accordance with this Section 10(b)(i)) a Notice of Holder Redemption in accordance herewith. 

(ii) If a Holder does not elect to exercise its Holder Redemption Right pursuant to this
Section 10(b) with respect to all of its shares of Series B Preferred Stock (and has not revoked such exercise in accordance with Section 10(b)(i)), the shares of Series B Preferred Stock held by
it and not surrendered for redemption by the Company will remain outstanding until otherwise subsequently converted, redeemed, reclassified or canceled. From and after the Redemption Date with respect to any share of Series B Preferred Stock for
which a Holder elected to effect a Holder Redemption Right and the Company has redeemed in accordance with the provisions of this Section 10(b), (i) Dividends shall cease to accrue on such share, (ii) such share shall
no longer be deemed outstanding and (iii) all rights with respect to such share shall cease and terminate. For the avoidance of doubt, notwithstanding anything contained herein to the contrary, until a share of Series B Preferred Stock is
redeemed by the payment in full of the applicable Redemption Price, such share of Series B Preferred Stock will remain outstanding and will be entitled to all of the powers, designations, preferences and other rights provided herein including the
right to convert. 

  
 13 

 (iii) In the event that a Holder Redemption Right is exercised with respect
to shares of Series B Preferred Stock representing less than all the shares of Series B Preferred Stock held by a Holder, upon such redemption, the Company shall execute and the Transfer Agent shall countersign and deliver to such Holder, at the
expense of the Company, a certificate representing the shares of Series B Preferred Stock held by the Holder as to which a Holder Redemption Right was not exercised (or book-entry interests representing such shares). 

(iv) If the Company shall not have sufficient funds legally available under the Texas Business Organizations Code to redeem all
outstanding shares of Series B Preferred Stock if it redeems outstanding shares of Series B Preferred Stock, the Company shall (i) redeem, pro rata among the Holders, a number of shares of Series B Preferred Stock with an aggregate Redemption
Price equal to the amount legally available for the redemption of shares of Series B Preferred Stock under the Texas Business Organizations Code and (ii) redeem any shares of Series B Preferred Stock not purchased because of the foregoing
limitations at the applicable Redemption Price as soon as practicable after the Company is able to make such redemption out of assets legally available for the purchase of such share of Series B Preferred Stock. The inability of the Company (or its
successor) to make a redemption payment for any reason shall not relieve the Company (or its successor) from its obligation to effect any required purchase when, as and if permitted by applicable law. If the Company fails to pay Redemption Price in
full when due in accordance with this Section 10 in respect of some or all of the shares of Series B Preferred Stock to be redeemed pursuant to this Section 10, the Dividend Rate on such shares
repurchased shall equal 12.0% per annum, which shall then increase by 0.50% on every three-month anniversary after such failure (but not, in any event, to greater than 14.0% per annum. Notwithstanding the foregoing, if a Holder Redemption Right is
exercised at a time when the Company is restricted or prohibited from redeeming some or all of the Series B Preferred Stock, the Company will use its commercially reasonable efforts to obtain the requisite consents to remove or obtain an exception
or waiver to such restrictions or prohibition. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity, including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Company’s failure to comply with its obligations under this Section 10. 

SECTION 11. [Reserved].  

SECTION 12. Adjustment for Reorganization Events. 

(a) Reorganization Events. In the event of: 

(i) any reclassification, statutory exchange, merger, consolidation or other similar business combination of the Company with
or into another Person, in each case, pursuant to which at least a majority of the Common Stock is changed or converted into, or exchanged for, cash, securities or other property of the Company or another Person; 

  
 14 

 (ii) any sale, transfer, lease or conveyance to another Person of all or a
majority of the property and assets of the Company, in each case pursuant to which the Common Stock is converted into cash, securities or other property; or 

(iii) any statutory exchange of securities of the Company with another Person (other than in connection with a merger or
acquisition) or reclassification, recapitalization or reorganization of the Common Stock into other securities; 
 (each of which is referred to as a
“Reorganization Event”), each share of Series B Preferred Stock outstanding immediately prior to such Reorganization Event will, without the consent of the Holders and subject to Section 12(d), remain
outstanding. 
 (b) Successive Reorganization Events. The above provisions of this Section 12 shall
similarly apply to successive Reorganization Events. 
 (c) Reorganization Event Notice. The Company (or any successor) shall, no less
than thirty (30) days prior to the anticipated effective date of any Reorganization Event, provide written notice to the Holders of such occurrence of such event and of the kind and amount of the cash, securities or other property that
constitutes the Exchange Property. Failure to deliver such notice shall not affect the operation of this Section 12. 

(d) Reorganization Event Agreements. The Company shall not enter into any agreement for a transaction constituting a Reorganization
Event unless to the extent that the Company is not the surviving corporation in such Reorganization Event or will be dissolved in connection with such Reorganization Event, proper provision shall be made in the agreements governing such
Reorganization Event for the conversion of the Series B Preferred Stock into stock of the Person surviving such Reorganization Event or such other continuing entity in such Reorganization Event. 

SECTION 13. Consent Rights. The vote or consent of the Holders of at least a majority of the shares of Series B Preferred Stock
outstanding at such time, voting together as a separate class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary for effecting or validating any of the following
actions, whether or not such approval is required pursuant to the Texas Business Organizations Code: 
 (a) any amendment,
alteration or repeal (whether by merger, consolidation or otherwise) of any provision of the Articles of Incorporation (including this Certificate of Designations) or Bylaws that would have an adverse effect on the rights, preferences, privileges or
voting power of the Series B Preferred Stock or the Holder thereof; 
 (b) any amendment or alteration (whether by merger,
consolidation or otherwise) of, or any supplement (whether by a certificate of designations or otherwise) to, the Articles of Incorporation or any provision thereof, or any other action to authorize or create, or increase the number of authorized or
issued shares of, or any securities convertible into shares of, or reclassify any security into, or issue, any Parity Stock or Senior Stock or any other class or series of Capital Stock of the Company ranking senior to, or on a parity basis with,
the Series B Preferred Stock as to dividend rights or rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company; 

  
 15 

 (c) any issuance of shares of Series B Preferred Stock after the Original
Issuance Date; 
 (d) on or prior to the Business Day immediately following the Stockholder Meeting, effect any action that
would result in (i) a change to the “Conversion Rate” or (ii) the obligation to pay “Participating Dividends”, in each case, as defined in the Series A Certificate of Designations; 

(e) any action that would cause the Company to cease to be treated as a domestic C corporation for U.S. federal income tax
purposes; and 
 (f) any incurrence of any Indebtedness of the Company or any of its Subsidiaries (other than (x) the
refinancing of any existing Indebtedness in an aggregate principal amount that does not exceed the then outstanding principal amount of the Indebtedness refinanced, plus all unpaid accrued or capitalized interest thereon, any prepayment premium
applicable thereto, any swap breakage costs or hedge termination costs related thereto, upfront fees and original issue discount on such refinancing indebtedness, and customary fees and expenses relating to such financing, and (y) ordinary
course of business working capital draws under the Company’s revolving credit facility) to the extent that, immediately after giving effect to such incurrence or refinancing, the ratio of the consolidated Indebtedness of the Company and its
Subsidiaries (net of unrestricted cash and cash equivalents of the Company and its Subsidiaries) to the EBITDA of the Company and its Subsidiaries for the most recently ended four fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred would not be less than a ratio of 5.15-to-1 on a pro forma basis after giving effect to
such incurrence and the use of the proceeds therefrom; 
 provided, however, (A) that, with respect to the occurrence of any of the events
set forth in clause (a) above, so long as (1) the Series B Preferred Stock remains outstanding with the terms thereof materially unchanged, or (2) the holders of the Series B Preferred Stock receive equity securities with rights,
preferences, privileges and voting power substantially the same as those of the Series B Preferred Stock, then the occurrence of such event shall not be deemed to adversely affect such rights, preferences, privileges or voting power of the Series B
Preferred Stock, and in such case such holders shall not have any voting rights with respect to the occurrence of any of the events set forth in clause (a) above and (B) that the authorization or creation of, or the increase in the number
of authorized or issued shares of, or any securities convertible into shares of, or the reclassification of any security (other than the Series B Preferred Stock) into, or the issuance of, Junior Stock will not require the vote the holders of the
Series B Preferred Stock. 
 For purposes of this Section 13, the filing in accordance with applicable law of a
certificate of designations or any similar document setting forth or changing the designations, powers, preferences, rights, qualifications, limitations and restrictions of any class or series of stock of the Company shall be deemed an amendment to
the Articles of Incorporation. 

  
 16 

 (b) Each Holder of Series B Preferred Stock will have one vote per share of Series B
Preferred Stock on any matter on which Holders of Series B Preferred Stock are entitled to vote separately as a class, whether at a meeting or by written consent. 

(c) The vote or consent of the Holders of a majority of the shares of Series B Preferred Stock outstanding at such time, voting together as a
single class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be sufficient to waive or amend the provisions of Section 9(e) of this Certificate of
Designations, and any amendment or waiver of any of the provisions of Section 9(e) approved by such percentage of the Holders shall be binding on all of the Holders. 

(d) For the avoidance of doubt and notwithstanding anything to the contrary in the Articles of Incorporation or Bylaws of the Company, the
Holders of Series B Preferred Stock shall have the exclusive consent and voting rights set forth in Section 13(b) and may take action or consent to any action with respect to such rights without a meeting by delivering a
consent in writing or by electronic transmission of the Holders of the Series B Preferred Stock entitled to cast not less than the minimum number of votes that would be necessary to authorize, take or consent to such action at a meeting of
stockholders. 
 SECTION 14. [Reserved]. 

SECTION 15. Preemptive Rights. Except for the right to participate in any issuance of new equity securities by the Company, as set
forth in the Investment Agreement, the Holders shall not have any preemptive rights. 
 SECTION 16. Term. Except as expressly
provided in this Certificate of Designations, the shares of Series B Preferred Stock shall not be redeemable or otherwise mature and the term of the Series B Preferred Stock shall be perpetual. 

SECTION 17. Creation of Capital Stock. Subject to Section 13(b)(ii), the Board, or any duly authorized
committee thereof, without the vote of the Holders, may authorize and issue additional shares of Capital Stock of the Company. 
 SECTION
18. No Sinking Fund. Shares of Series B Preferred Stock shall not be subject to or entitled to the operation of a retirement or sinking fund. 

SECTION 19. Transfer Agent, Conversion Agent, Registrar and Paying Agent. The duly appointed Transfer Agent, Conversion Agent,
Registrar and paying agent for the Series B Preferred Stock shall be Computershare Trust Company, N.A. The Company may, in its sole discretion, appoint any other Person to serve as Transfer Agent, Conversion Agent, Registrar or paying agent for the
Series B Preferred Stock and thereafter may remove or replace such other Person at any time. Upon any such appointment or removal, the Company shall send notice thereof by first class mail, postage prepaid, to the Holders. 

SECTION 20. Replacement Certificates. (a) Mutilated, Destroyed, Stolen and Lost Certificates. If physical certificates
evidencing the Series B Preferred Stock are issued, the Company shall replace any mutilated certificate at the Holder’s expense upon surrender of that certificate to the Transfer Agent. The Company shall replace certificates that become
destroyed, stolen or lost at the Holder’s expense upon delivery to the Company and the Transfer Agent of satisfactory evidence that the certificate has been destroyed, stolen or lost, together with any indemnity that may be required by the
Transfer Agent and the Company. 

  
 17 

 (b) Certificates Following Conversion. If physical certificates representing the
Series B Preferred Stock are issued, the Company shall not be required to issue replacement certificates representing shares of Series B Preferred Stock on or after the Conversion Date applicable to such shares. In place of the delivery of a
replacement certificate following the Conversion Date, the Transfer Agent, upon receipt of the satisfactory evidence and indemnity described in clause (a) above, shall deliver the shares of Series A Preferred Stock issuable upon conversion of
such shares of Series B Preferred Stock formerly evidenced by the physical certificate. 
 SECTION 21. Taxes. (a) Transfer
Taxes. The Company shall pay any and all stock transfer, documentary, stamp and similar taxes that may be payable in respect of any issuance or delivery of shares of Series B Preferred Stock or shares of Series A Preferred Stock or other
securities issued on account of Series B Preferred Stock pursuant hereto or certificates representing such shares or securities. However, in the case of conversion of Series B Preferred Stock, the Company shall not be required to pay any such tax
that may be payable in respect of any transfer involved in the issuance or delivery of shares of Series B Preferred Stock, shares of Series A Preferred Stock or other securities to a beneficial owner other than the beneficial owner of the Series B
Preferred Stock immediately prior to such conversion, and shall not be required to make any such issuance, delivery or payment unless and until the Person otherwise entitled to such issuance, delivery or payment has paid to the Company the amount of
any such tax or has established, to the satisfaction of the Company, that such tax has been paid or is not payable. 
 (b)
Withholding. All payments and distributions (or deemed distributions) on the shares of Series B Preferred Stock (and on the shares of Series A Preferred Stock received upon their conversion) shall be subject to withholding and backup
withholding of taxes to the extent required by law, subject to applicable exemptions, and amounts withheld, if any, shall be treated as received by the Holders. 

SECTION 22. Notices. All notices referred to herein shall be in writing and, unless otherwise specified herein, all notices hereunder
shall be deemed to have been given (a) upon the earlier of receipt thereof or three (3) Business Days after the mailing thereof if sent by registered or certified mail with postage prepaid, or by private courier service addressed:
(i) if to the Company, to its office at Zix Corporation, 2711 N. Haskell Avenue, Suite 2200, LB 36, Dallas, Texas 75204-2960 (Attention: General Counsel), (ii) if to any Holder, to such Holder at the address of such Holder as listed in the
stock record books of the Company (which may include the records of the Transfer Agent) or (iii) to such other address as the Company or any such Holder, as the case may be, shall have designated by notice similarly given; or (b) on the
date sent by facsimile or transmitted to an email address designated by the Company or any such Holder if sent during normal business hours, and on the next Business Day if sent after normal business hours of the recipient. 

  
 18 

 SECTION 23. Facts Ascertainable. When the terms of this Certificate of Designations
refers to a specific agreement or other document to determine the meaning or operation of a provision hereof, the Secretary of the Company shall maintain a copy of such agreement or document at the principal executive offices of the Company and a
copy thereof shall be provided free of charge to any Holder who makes a request therefor. The Secretary of the Company shall also maintain a written record of the Issuance Date, the number of shares of Series B Preferred Stock issued to a Holder and
the date of each such issuance, and shall furnish such written record free of charge to any Holder who makes a request therefor. 
 SECTION
24. Waiver. Notwithstanding any provision in this Certificate of Designations to the contrary, any provision contained herein and any right of the Holders of Series B Preferred Stock granted hereunder may be waived as to all shares of Series
B Preferred Stock (and the Holders thereof) upon the vote or written consent of the Holders of a majority of the shares of Series B Preferred Stock then outstanding. 

SECTION 25. Severability. If any term of the Series B Preferred Stock set forth herein is invalid, unlawful or incapable of being
enforced by reason of any rule of law or public policy, all other terms set forth herein which can be given effect without the invalid, unlawful or unenforceable term will, nevertheless, remain in full force and effect, and no term herein set forth
will be deemed dependent upon any other such term unless so expressed herein. 
 SECTION 26. Business Opportunities. To the fullest
extent permitted by Section 2.101(21) of the Texas Business Organizations Code (or any successor provision) and except as may be otherwise expressly agreed in writing by the Company and the Investor Parties, the Company, on behalf of itself and
its Subsidiaries, renounces any interest or expectancy of the Company and its Subsidiaries in, or in being offered an opportunity to participate in, business opportunities, that are from time to time presented to the Investor Parties or any of their
respective officers, representatives, directors, agents, stockholders, members, partners, Affiliates, Subsidiaries (other than the Company and its Subsidiaries), or any of their respective designees on the Company’s Board and/or any of their
respective representatives who, from time to time, may act as officers of the Company, even if the opportunity is one that the Company or its Subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted
the opportunity to do so, and no such person shall be liable to the Company or any of its Subsidiaries for breach of any fiduciary or other duty, as a director or officer or otherwise, by reason of the fact that such person pursues or acquires such
business opportunity, directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Company or its Subsidiaries unless, in the case of any such person
who is a director or officer of the Company, such business opportunity is expressly offered to such director or officer in writing solely in his or her capacity as a director or officer of the Company. Any Person purchasing or otherwise acquiring
any interest in any shares of Capital Stock of the Company shall be deemed to have notice of and consented to the provisions of this Section 26. Neither the alteration, amendment or repeal of this
Section 26, nor the adoption of any provision of the Articles of Incorporation or this Certificate of Designations inconsistent with this Section 26, nor, to the fullest extent permitted by Texas
law, any modification of law, shall eliminate or reduce the effect of this Section 26 in respect of any business opportunity first identified or any other matter occurring, or any cause of action, suit or claim that, but
for this Section 26, would accrue or arise, prior to such alteration, amendment, repeal, adoption or modification. If any provision or provisions of this Section 26 shall be held to be invalid,
illegal or unenforceable as applied to any circumstance for any reason 

  
 19 

 
whatsoever: (a) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Section 26
(including, without limitation, each portion of any paragraph of this Section 26 containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable)
shall not in any way be affected or impaired thereby and (b) to the fullest extent possible, the provisions of this Section 26 (including, without limitation, each such portion of any paragraph of this
Section 26 containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Company to protect its directors, officers, employees and agents from personal liability in
respect of their good faith service to or for the benefit of the Company to the fullest extent permitted by law. This Section 26 shall not limit any protections or defenses available to, or indemnification or advancement
rights of, any director, officer, employee or agent of the Company under the Articles of Incorporation, the Bylaws, any other agreement between the Company and such director, officer, employee or agent or applicable law.

 REGISTRATION RIGHTS AGREEMENT 

This REGISTRATION RIGHTS AGREEMENT (this “Agreement”) is entered into as of [•], 2019 by and among ZIX CORPORATION, a
Texas corporation (the “Company”), and TRUE WIND CAPITAL, L.P. (together with its successors and assigns, the “Investor”). Capitalized terms used but not defined elsewhere herein are defined in Exhibit A. The
Investor and any other party that may become a party hereto pursuant to Section 4.1 are referred to collectively as the “Stockholders” and individually each as a “Stockholder”. 

WHEREAS, the Company and the Investor are parties to the Investment Agreement, dated as of January 14, 2019 (as amended from time to
time, the “Investment Agreement”), pursuant to which the Company is selling to the Investor, and the Investor is purchasing from the Company, an aggregate of 64,914 shares of the Series A Preferred Stock (the “Series A
Preferred Stock”), which is convertible into shares of Common Stock, and an aggregate of 35,086 shares of the Series B Preferred Stock (the “Series A Preferred Stock”), which is convertible into shares of Series A Preferred
Stock; 
 WHEREAS, as a condition to the obligations of the Company and the Investor under the Investment Agreement, the Company and the
Investor are entering into this Agreement for the purpose of granting certain registration and other rights to the Stockholders. 
 NOW,
THEREFORE, in consideration of the mutual covenants and agreements contained in this Agreement, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows: 

ARTICLE I 
 Resale Shelf
Registration 
 Section 1.1 Resale Shelf Registration Statement. Subject to the other applicable provisions of this
Agreement, the Company shall use its commercially reasonable efforts to prepare and file within 120 days after the date hereof a registration statement covering the sale or distribution from time to time by the Holders, on a delayed or continuous
basis pursuant to Rule 415 of the Securities Act, of all of the Registrable Securities on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, then such registration shall be on another appropriate form and shall provide for the registration of such Registrable Securities for resale by the Holders in accordance with any reasonable method of
distribution elected by the Investor) (the “Resale Shelf Registration Statement”) and shall use its commercially reasonable efforts to cause such Resale Shelf Registration Statement to be declared effective by the SEC as promptly as
is reasonably practicable after the filing thereof. 
 Section 1.2 Effectiveness Period. Once declared effective, the
Company shall, subject to the other applicable provisions of this Agreement, use its commercially reasonable efforts to cause the Resale Shelf Registration Statement to be continuously effective and usable until such time as there are no longer any
Registrable Securities (the “Effectiveness Period”). 

  

 Section 1.3 Subsequent Shelf Registration Statement. If any Shelf
Registration Statement ceases to be effective under the Securities Act for any reason at any time during the Effectiveness Period, the Company shall use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf
Registration Statement to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration Statement), and shall use its commercially reasonable efforts
to as promptly as is reasonably practicable amend such Shelf Registration Statement in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf Registration Statement or file an additional
registration statement (a “Subsequent Shelf Registration Statement”) for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act registering the resale from time to time by the Holders
thereof of all securities that are Registrable Securities as of the time of such filing. If a Subsequent Shelf Registration Statement is filed, the Company shall use its commercially reasonable efforts to (a) cause such Subsequent Shelf
Registration Statement to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof and (b) keep such Subsequent Shelf Registration Statement continuously effective and usable until the end of
the Effectiveness Period. Any such Subsequent Shelf Registration Statement shall be a registration statement on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent
Shelf Registration Statement shall be on another appropriate form and shall provide for the registration of such Registrable Securities for resale by the Holders in accordance with any reasonable method of distribution elected by the Investor. 

Section 1.4 Supplements and Amendments. The Company shall supplement and amend any Shelf Registration Statement if required
by the Securities Act or the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement. 

Section 1.5 Subsequent Holder Notice. If a Person entitled to the benefits of this Agreement becomes a Holder of
Registrable Securities after a Shelf Registration Statement becomes effective under the Securities Act, the Company shall, as promptly as is reasonably practicable following delivery of written notice to the Company of such Person becoming a Holder
and requesting for its name to be included as a selling securityholder in the prospectus related to the Shelf Registration Statement (a “Subsequent Holder Notice”): 

(a) if required and permitted by applicable law, file with the SEC a supplement to the related prospectus or a post-effective amendment to the
Shelf Registration Statement so that such Holder is named as a selling securityholder in the Shelf Registration Statement and the related prospectus in such a manner as to permit such Holder to deliver a prospectus to purchasers of the Registrable
Securities in accordance with applicable law; provided, however, that the Company shall not be required to file more than one post-effective amendment or a supplement to the related prospectus for such purpose in any 90-day period; 
 (b) if, pursuant to Section 1.5(a), the Company shall have
filed a post-effective amendment to the Shelf Registration Statement that is not automatically effective, use its commercially reasonable efforts to cause such post-effective amendment to become effective under the Securities Act as promptly as is
reasonably practicable; and 

  
 2 

 (c) notify such Holder as promptly as is reasonably practicable after the effectiveness
under the Securities Act of any post-effective amendment filed pursuant to Section 1.5(a). 
 Section 1.6
Underwritten Offering. 
 (a) Subject to any applicable restrictions on transfer in the Investment Agreement or otherwise, the
Investor may, after the Resale Shelf Registration Statement becomes effective, deliver a written notice to the Company (the “Underwritten Offering Notice”) specifying that the sale of some or all of the Registrable Securities
subject to the Shelf Registration Statement, is intended to be conducted through an underwritten offering (the “Underwritten Offering”); provided, however, that the Holders of Registrable Securities may not, without
the Company’s prior written consent, (i) launch an Underwritten Offering the anticipated gross proceeds of which shall be less than $10,000,000 (unless the Holders are proposing to sell all of their remaining Registrable Securities), (ii)
launch more than four Underwritten Offerings at the request of the Holders within any three-hundred sixty-five (365) day-period or (iii) launch an Underwritten Offering within the period (a
“Quarterly Blackout Period”) commencing fourteen (14) days prior to and ending two (2) days following the Company’s scheduled earnings release date for any fiscal quarter or year. 

(b) In the event of an Underwritten Offering, the Stockholders participating in such Underwritten Offering shall select the managing
underwriter(s) to administer the Underwritten Offering; provided, that the choice of such managing underwriter(s) shall be subject to the consent of the Company, which is not to be unreasonably withheld. In making the determination to consent
to the Stockholder’s choice of managing underwriter(s), the Company may take into account its business and strategic interests. The Company, the Investor and the Holders of Registrable Securities participating in an Underwritten Offering will
enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such offering. 
 (c) The
Company will not include in any Underwritten Offering pursuant to this Section 1.6 any securities that are not Registrable Securities without the prior written consent of the Investor. If the managing underwriter or
underwriters advise the Company and the Investor in writing that in its or their good faith opinion the number of Registrable Securities (and, if permitted hereunder, other securities requested to be included in such offering) exceeds the number of
securities which can be sold in such offering in light of market conditions or is such so as to adversely affect the success of such offering, the Company will include in such offering only such number of securities that can be sold without
adversely affecting the marketability of the offering, which securities will be so included in the following order of priority: (i) first, the Registrable Securities of the Holders that have requested to participate in such Underwritten
Offering, allocated pro rata among such Holders on the basis of the percentage of the Registrable Securities requested to be included in such offering by such Holders, and (ii) second, any other securities of the Company that have been
requested to be so included.

 Section 1.7 Take-Down Notice. Subject to the other applicable provisions
of this Agreement, at any time that any Shelf Registration Statement is effective, if the Investor delivers a notice to the Company (a “Take-Down Notice”) stating that it intends to effect a sale or distribution of all or part of
its Registrable Securities included by it on any Shelf Registration Statement (a “Shelf Offering”) and stating the number of the Registrable Securities to be included in such Shelf Offering, then the Company shall amend, subject to
the other applicable provisions of this Agreement or supplement the Shelf Registration Statement as may be necessary in order to enable such Registrable Securities to be sold and distributed pursuant to the Shelf Offering. 

Section 1.8 Piggyback Registration. 

(a) If the Company proposes to file a registration statement under the Securities Act with respect to an offering of Common Stock or securities
convertible into, or exchangeable or exercisable for, Common Stock, whether or not for sale for its own account (other than a registration statement (i) on Form S-4, Form
S-8 or any successor forms thereto or (ii) filed to effectuate an exchange offer or any employee benefit or dividend reinvestment plan), then the Company shall give prompt written notice of such filing,
which notice shall be given, to the extent reasonably practicable, no later than five (5) Business Days prior to the filing date (the “Piggyback Notice”) to the Investor on behalf of the Holders of Registrable Securities. The
Piggyback Notice shall offer such Holders the opportunity to include (or cause to be included) in such registration statement the number of shares of Registrable Securities as each such Holder may request (each, a “Piggyback Registration
Statement”). Subject to Section 1.8(b), the Company shall include in each Piggyback Registration Statement all Registrable Securities with respect to which the Company has received written requests for inclusion
therein (each, a “Piggyback Request”) within five (5) Business Days after the date of the Piggyback Notice but in any event not later than one (1) Business Day prior to the filing date of a Piggyback Registration
Statement. The Company shall not be required to maintain the effectiveness of a Piggyback Registration Statement beyond the earlier of (x) 180 days after the effective date thereof and (y) consummation of the distribution by the Holders of the
Registrable Securities included in such registration statement. 
 (b) If any of the securities to be registered pursuant to the registration
giving rise to the rights under this Section 1.8 are to be sold in an underwritten offering, the Company shall use commercially reasonable efforts to cause the managing underwriter or underwriters of a proposed underwritten
offering to permit Holders of Registrable Securities who have timely submitted a Piggyback Request in connection with such offering to include in such offering all Registrable Securities included in each Holder’s Piggyback Request on the same
terms and subject to the same conditions as any other shares of capital stock, if any, of the Company included in the offering. Notwithstanding the foregoing, if the managing underwriter or underwriters of such underwritten offering advise the
Company in writing that in its or their good faith opinion the number of securities exceeds the number of securities which can be sold in such offering in light of market conditions or is such so as to adversely affect the success of such offering,
the Company will include in such offering only such number of securities that can be sold without adversely affecting the marketability of the offering, which securities will be so included in the following order of priority: (i) first, the
securities proposed to be sold by the Company for its own account; (ii) second, the Registrable Securities of the Holders that have requested to participate in such underwritten offering, allocated pro rata among such Holders on the
basis of the percentage of the Registrable Securities requested to be included in such offering by such Holders; (iii) third, any other securities of the Company that have been requested to be 

  
 4 

 
included in such offering; provided, that Holders may, prior to the earlier of the (a) effectiveness of the registration statement and (b) the time at which the offering
price or underwriter’s discount is determined with the managing underwriter or underwriters, withdraw their request to be included in such registration pursuant to this Section 1.8. 

Section 1.9 Rule 144A Sales. Holders of Registrable Securities that are eligible for resale pursuant to Rule 144A under
the Securities Act shall have analogous rights to sell such securities in a marketed offering under Rule 144A under the Securities Act through one or more initial purchasers on a firm-commitment basis, using procedures that are substantially
equivalent to those specified in Article I and Article II of this Agreement. The Company agrees to use its reasonable efforts to cooperate to effect any such sales under such Rule 144A. Nothing in this Section 1.9 shall impose any additional or
more burdensome obligations on the Company than would apply under Article I and Article II, in each case, mutatis mutandis in respect of a registered Underwritten Offering (including the estimated gross proceeds minimum set forth in
Section 1.6(a)), or require that the Company take any actions that it would not be required to take in an Underwritten Offering of such Registrable Securities. 

ARTICLE II

 5 

 
securities and make all required filings of such prospectus supplement or post-effective amendment as soon as reasonably practicable after the Company has received such request; provided,
however, that the Company shall not be required to take any actions under this Section 2.1(d) that are not, in the opinion of counsel for the Company, in compliance with applicable law;

registration statement or the related prospectus or any document incorporated therein by reference or file any other required document and at the request of the Investor, furnish to the Investor a reasonable number of copies of a supplement to or an

that would subject it to general service of process in any such jurisdictions; 
 (h) in the event that the Registrable

(j) use commercially reasonable efforts to furnish, on the date that such Registrable Securities are delivered to the
underwriters for sale, if such securities are being sold through underwriters, (i) an opinion dated such date of the legal counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to

any event of the kind described in Section 2.1(f), 2.1(o)(ii) or 2.1(o)(iii), the Investor shall discontinue, and shall cause each Holder to discontinue, disposition of any Registrable Securities covered by
such registration statement or the related prospectus until receipt of the copies of the supplemented or amended prospectus, which supplement or amendment shall, subject to the other applicable provisions of this Agreement, be prepared and furnished
as soon as reasonably practicable, or until the Investor is advised in writing by the Company that the use of the applicable prospectus may be resumed, and have received copies of any amended or supplemented prospectus or any additional or
supplemental filings which are incorporated, or deemed to be incorporated, by reference in such prospectus (such period during which disposition is discontinued being an “Interruption Period”) and, if requested by the Company, the
Investor shall use commercially reasonable efforts to return, and cause the Holders to return, to the Company all copies then in their possession, of the prospectus covering such Registrable Securities at the time of receipt of such request. As soon
as practicable after the Company has determined that the use of the applicable prospectus may be resumed, the Company will notify the Investor thereof. In the event the Company invokes an Interruption Period hereunder and in the reasonable

applicable. 
 Section 2.2 Suspension. (a) The Company shall be entitled, on one (1) occasion in any one-hundred eighty (180) day period, for a period of time not to exceed ninety (90) days in the aggregate in any twelve (12) month period (any such period a “Suspension Period”), to

disposition or other similar transaction involving the Company or any of its subsidiaries then under consideration. Such certificate shall contain a statement of the reasons for such suspension and an approximation of the anticipated length of such
suspension. The Investor shall keep the information contained in such certificate confidential subject to the same terms set forth in Section 2.1(m). If the Company defers any registration of Registrable Securities in
response to an Underwritten Offering Notice or requires the Investor or the Holders to suspend any Underwritten Offering, the Investor shall be entitled to withdraw such Underwritten Offering Notice and if it does so, such request shall not be
treated for any purpose as the delivery of an Underwritten Offering Notice pursuant to Section 1.6.

pursuant to Article I shall be borne by the Company. All Selling Expenses relating to securities registered on behalf of the Holders shall be borne by the Holders of the Registrable Securities included in such registration.

reasonably practicable after the receipt of written notice from such Indemnified Party of such claim or proceeding, to assume, at the Indemnifying Party’s expense, the defense of any such
claim or litigation, with counsel reasonably satisfactory to the Indemnified Party and, after notice from the Indemnifying Party to such Indemnified Party of its election to assume the defense thereof, the Indemnifying Party will not (so long as it
shall continue to have the right to defend, contest, litigate and settle the matter in question in accordance with this paragraph) be liable to such Indemnified Party hereunder for any legal expenses and other expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof; provided, however, that an Indemnified Party shall have the right to employ separate counsel in any such claim or litigation, but the fees and expenses of such counsel shall be
at the expense of such Indemnified Party unless the Indemnifying Party shall have failed within a reasonable period of time to assume such defense and the Indemnified Party is or would reasonably be expected to be materially prejudiced by such
delay. The failure of any Indemnified Party to give notice as provided herein shall relieve an Indemnifying Party of its obligations under this Article III only to the extent that the failure to give such notice is materially prejudicial or
harmful to such Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the prior written consent of each Indemnified Party (which consent shall not be
unreasonably withheld or delayed), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation. The indemnity agreements contained in this Article III shall not apply to amounts paid in settlement of any claim, loss, damage, liability or action if such settlement is effected without the
prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. The indemnification set forth in this Article III shall be in addition to any other indemnification rights or
agreements that an Indemnified Party may have. An Indemnifying Party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by
such Indemnifying Party with respect to such claim, unless in the reasonable judgment of any Indemnified Party a conflict of interest may exist between such Indemnified Party and any other Indemnified Parties with respect to such claim. 

Section 3.4 Contribution. If the indemnification provided for in this Article III is held by a court of competent
jurisdiction to be unavailable to an Indemnified Party, other than pursuant to its terms, with respect to any Losses or action referred to therein, then, subject to the limitations contained in this Article III, the Indemnifying Party, in
lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses or action in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party, on the one hand, and the Indemnified Party, on the other, in connection with the actions, statements or omissions that resulted in such Losses or action, as well as any other relevant equitable considerations. The relative fault
of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other hand, shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact, has been made (or omitted) by, or relates to information supplied by such Indemnifying Party or such Indemnified Party, and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent any such action, statement or omission. The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 3.4

  
 14 

 
was determined solely upon pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding
sentence of this Section 3.4. Notwithstanding the foregoing, the amount each Investor or any Holder will be obligated to contribute pursuant to this Section 3.4 will be limited to an amount equal
to the net proceeds received by such Investor or Holder in respect of the Registrable Securities sold pursuant to the registration statement which gives rise to such obligation to contribute. No Person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

ARTICLE IV 
 Transfer and
Termination of Registration Rights 
 Section 4.1 Transfer of Registration Rights. Any rights to cause the Company to
register securities granted to a Holder under this Agreement may be transferred or assigned to any Person in connection with a Transfer (as defined in the Investment Agreement) of Series A Preferred Stock, Series B Preferred Stock or Common Stock to
such Person in a Transfer permitted by Section 5.08(b)(i) of the Investment Agreement or a lender in connection with a Permitted Loan (as defined in the Investment Agreement); provided, however, that (a) prior written notice
of such assignment of rights is given to the Company and (b) such transferee agrees in writing to be bound by, and subject to, this Agreement as a “Holder” pursuant to a written instrument in form and substance reasonably acceptable
to the Company. 
 Section 4.2 Termination of Registration Rights. The rights of any particular Holder to cause the
Company to register securities under Article I shall terminate with respect to such Holder upon the date upon which such Holder no longer holds any Registrable Securities. 

ARTICLE V 
 Miscellaneous

 Section 5.1 Amendments and Waivers. Subject to compliance with applicable law, this Agreement may be amended or
supplemented in any and all respects by written agreement of the Company and the Investor. 
 Section 5.2 Extension of Time,
Waiver, Etc. The parties hereto may, subject to applicable law, (a) extend the time for the performance of any of the obligations or acts of the other party or (b) waive compliance by the other party with any of the agreements
contained herein applicable to such party or, except as otherwise provided herein, waive any of such party’s conditions. Notwithstanding the foregoing, no failure or delay by the parties hereto in exercising any right 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 hereunder. Any agreement on the part of a party hereto to any such extension or waiver shall be valid
only if set forth in an instrument in writing signed on behalf of such party; provided, that the Investor may execute such waivers on behalf of any Stockholder. 

  
 15 

 Section 5.3 Assignment. Except as provided in
Section 4.1, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of law or otherwise, by any of the parties hereto without the prior written
consent of the other party hereto; provided, however, that the Investor may provide any such consent on behalf of the Stockholders; provided, further, that if the Company consolidates or merges with or into any Person and
the Common Stock or any other Registrable Securities are, in whole or in part, converted into or exchanged for securities of a different issuer, and any Stockholder would, upon completion of such merger or consolidation, hold Registrable Securities
of such issuer, then as a condition to such transaction the Company will cause such issuer to assume all of the Company’s rights and obligations under this Agreement in a written instrument delivered to the Stockholders. 

Section 5.4 Counterparts. This Agreement may be executed in one or more counterparts (including by facsimile or electronic mail),
each of which shall be deemed to be an original but all of which taken together shall constitute one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the
other parties hereto. 
 Section 5.5 Entire Agreement; No Third Party Beneficiary. This Agreement, including the
Transaction Documents (as defined in the Investment Agreement), constitutes the entire agreement, and supersedes all other prior agreements and understandings, both written and oral, among the parties and their Affiliates, or any of them, with
respect to the subject matter hereof and thereof. No provision of this Agreement shall confer upon any Person other than the parties hereto and their permitted assigns and the Indemnified Parties any rights or remedies hereunder. 

Section 5.6 Governing Law; Jurisdiction. 

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York applicable to contracts executed
in and to be performed entirely within that State, regardless of the laws that might otherwise govern under any applicable conflict of laws principles. 

(b) All legal or administrative proceedings, suits, investigations, arbitrations or actions (“Actions”) arising out of
or relating to this Agreement shall be heard and determined in the county of New York in the State of New York and the parties hereto hereby irrevocably submit to the exclusive jurisdiction and venue of such courts in any such Action and irrevocably
waive the defense of an inconvenient forum or lack of jurisdiction to the maintenance of any such Action. The consents to jurisdiction and venue set forth in this Section 5.6 shall not constitute general consents to service
of process in the State of New York and shall have no effect for any purpose except as provided in this paragraph and shall not be deemed to confer rights on any Person other than the parties hereto. Each party hereto agrees that service of process
upon such party in any Action arising out of or relating to this Agreement shall be effective if notice is given by overnight courier at the address set forth in Section 5.9 of this Agreement. The parties hereto agree that
a final judgment in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law; provided, however, that nothing in the foregoing shall
restrict any party’s rights to seek any post-judgment relief regarding, or any appeal from, a final trial court judgment. 

  
 16 

 Section 5.7 Specific Enforcement. The parties acknowledge and agree that
(a) the parties shall be entitled to an injunction or injunctions, specific performance or other equitable relief to enforce specifically the terms and provisions hereof in the courts described in Section 5.6 without
proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement and (b) the right of specific enforcement is an integral part of this Agreement and without that right, neither the
Company nor the Investor would have entered into this Agreement. The parties hereto agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, and agree not to assert that a
remedy of monetary damages would provide an adequate remedy or that the parties otherwise have an adequate remedy at law. The parties hereto acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 5.7 shall not be required to provide any bond or other security in connection with any such order or
injunction. 
 Section 5.8 Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE
UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) IT UNDERSTANDS AND HAS CONSIDERED THE
IMPLICATIONS OF SUCH WAIVER, (C) IT MAKES SUCH WAIVER VOLUNTARILY AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 5.8. 

Section 5.9 Notices. All notices, requests and other communications to any party hereunder shall be in writing and shall be deemed
