Safe Harbor Forward-looking Statements This presentation includes “forward-looking statements,” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are based on various facts and derived utilizing important assumptions, current expectations, estimates and projections and are subject to known and unknown risks, uncertainties and other factors that may cause actual results, performance, outcomes or achievements to be materially different from any future results, performance, outcomes or achievements expressed or implied by such forward-looking statements. Forward-looking statements include, without limitation, statements relating to the impact Green or Veritex expect the proposed transaction to have on the combined entity’s operations, financial condition, and financial results, and Green’s or Veritex’s expectations about the ability to successfully integrate the combined businesses and the amount of cost savings and overall operational efficiencies expected to be realized as a result of the proposed transaction. The forward-looking statements may also include statements about Green’s, Veritex’s or the combined company’s future financial performance, business and growth strategy, projected plans and objectives, as well as other projections based on macroeconomic and industry trends, which are inherently unreliable due to the multiple factors that impact economic trends, and any such variations may be material. Statements preceded by, followed by or that otherwise include the words “believes,” “expects,” “anticipates,” “intends,” “projects,” “estimates,” “plans” and similar expressions or future or conditional verbs such as “will,” “should,” “would,” “may” and “could” are generally forward-looking in nature and not historical facts, although not all forward-looking statements include the foregoing. Further, certain factors that could affect future results and cause actual results to differ materially from those expressed in the forward-looking statements include, but are not limited to, the possibility that the proposed transaction does not close when expected or at all because required regulatory, shareholder or other approvals or other conditions to closing are not received or satisfied on a timely basis or at all, the failure to close for any other reason, changes in Veritex’s share price before closing, that the businesses of Veritex and Green will not be integrated successfully, that the cost savings and any synergies from the proposed transaction may not be fully realized or may take longer to realize than expected, disruption from the proposed transaction making it more difficult to maintain relationships with employees, customers or other parties with whom Veritex and/or Green have business relationships, diversion of management time on transaction-related issues, risks relating to the potential dilutive effect of shares of Veritex common stock to be issued in the proposed transaction, the reaction to the transaction of the companies’ customers, employees and counterparties and other factors, many of which are beyond the control of Veritex and Green. We refer you to the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of Veritex’s Annual Report on Form 10-K for the year ended December 31, 2017, the Annual Report on Form 10-K filed by Green for the year ended December 31, 2017, the Joint Proxy/Prospectus in the Form S-4 filed by Veritex on October 10, 2018 and any updates to those risk factors set forth in Veritex’s and Green’s Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings, which have been filed with the SEC and are available on the SEC’s website at www.sec.gov. If one or more events related to these or other risks or uncertainties materialize, or if Green’s or Veritex’s underlying assumptions prove to be incorrect, actual results may differ materially from what Veritex or Green anticipates. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made. Neither Veritex nor Green undertakes any obligation, and specifically declines any obligation, to update or revise any forward-looking statements, whether as a result of new information, future developments or otherwise. All forward-looking statements, expressed or implied, included in this presentation are expressly qualified in their entirety by the cautionary statements contained or referred to herein. In addition to factors previously disclosed in Green Bancorp’s reports filed with the SEC and those identified elsewhere in this communication, the following factors among others, could cause actual results to differ materially from forward-looking statements: changes in asset quality and credit risk; the inability to sustain revenue and earnings growth; changes in interest rates and capital markets; inflation; customer borrowing, repayment, investment and deposit practices; customer disintermediation; the introduction, withdrawal, success and timing of business initiatives; competitive conditions; the inability to realize cost savings or revenues or to implement integration plans and other consequences associated with mergers, acquisitions and divestitures; economic conditions; and the impact, extent and timing of technological changes, capital management activities, and other actions of the Federal Reserve Board and legislative and regulatory actions and reforms. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results. 3
