 shareholder approval of the Plurality Voting Amendment. All other sections of the Existing Articles would be maintained in their current form (except to the extent an amendment is approved pursuant to Proposals 4, 6, 7, or 8). For the avoidance of doubt, approval of the proposed amendments contained in Proposals 4, 6, 7, or 8 by the shareholders would not impact the Plurality Voting Amendment.

Our Board of Directors reserves the right to elect to abandon the Plurality Voting Amendment at any time before it becomes effective even if it is approved by the shareholders. If the shareholders do not approve the Plurality Voting Amendment, our Existing Articles would remain in effect in their entirety (except to the extent they are amended pursuant to Proposals 4, 6, 7, or 8).

| Approval of Amendment to the Articles of Incorporation to Limit the Liability of Certain Officers as Permitted by Texas and Virginia Law                                                                                                                                                             
 The Board of Directors has unanimously approved, and recommends that shareholders approve, an amendment to our Existing Articles to be contained in an Amended and Restated Charter to limit the liability of certain officers as permitted by Texas and Virginia law (the “Exculpation Amendment”). |     | The Board of Directors recommends that our shareholders voteFORthe approval of an amendment to the Existing Articles to provide for exculpation of officers as permitted by Texas and Virginia Law. |

In 2025, the State of Texas (one state in which the Company is incorporated) enacted legislation that expands exculpation protection to officers, thereby enabling companies to eliminate the monetary liability of certain officers in certain circumstances, similar to the protection already afforded to directors under our Existing Articles as permitted by Texas law. To adopt such exculpation provisions, however, a corporation must make an affirmative election in its charter. Similar to Texas, Virginia (also where the Corporation is incorporated) law also permits exculpation of officers when stated in a corporation’s charter. The Exculpation Amendment does not permit the elimination of liability of officers for any breach of the duty of loyalty to the Company or its shareholders, for acts or omissions not in good faith that constitute a breach of a duty of the officer to the Company or that involve intentional misconduct or a knowing violation of the law, for a transaction from which the officer received an improper benefit, or for an act or omission
