**Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.**

Item 6 of Schedule 13D is hereby amended to insert the following as new final paragraph therein:

Based solely on a Schedule 13D/A and Form 4 filed by Gregory M. Shephard with the SEC on January 2, 2026, Mr. Shephard entered into a multi-tranche, prepaid variable share forward sale transaction on December 31, 2025, pursuant to a Stock Purchase Agreement (the "Agreement") among Mr. Shephard and UBS SECURITIES LLC and UBS FINANCIAL SERVICES INC., each as agents and UBS AG, STAMFORD BRANCH ("Buyer") relating to an aggregate of 532,500 shares of Common Stock and obligating Mr. Shephard to deliver to the Buyer up to an aggregate of 532,500 shares of Common Stock (or, at Mr. Shephard's election, under certain circumstances, an equivalent amount of cash) to settle each tranche of the Agreement. The transaction maturity dates are January 8-22, 2029, with each maturity date representing a tranche. Pursuant to a Pledge Agreement, Mr. Shephard pledged 532,500 shares of Common Stock (the "Pledged Shares") to secure his obligations under the Agreement, and retained voting and ordinary dividend rights in the Pledged Shares during the term of the pledge (and thereafter if Mr. Shephard settles the Agreement in cash). Under the Agreement, on the first business day immediately following the maturity date for each tranche, Mr. Shephard agrees to deliver to Buyer a number of shares of unrestricted stock (or an equivalent amount of cash, if cash settled) equal to the product of (A) the number of shares in such tranche and (B) (i) if the closing price per share of Common Stock on the maturity date (the "Settlement Price") is less than $12.72 ("Cap Level") but greater than $8.14 ("Floor Level"), a ratio equal to the Floor Level divided by the Settlement Price, (ii) if the Settlement Price is equal to or greater than the Cap Level, a ratio equal to a fraction with a numerator equal to the sum of (1) the Floor Level and (2) the excess, if any, of the Settlement Price over the Cap Level, and a denominator equal to the Settlement Price, and (iii) if the Settlement Price is equal to or less than the Floor Level, one (1).
