SOUTHSIDE BANCSHARES INC

The Bank has split dollar agreements with Lee R. Gibson, effective September 7, 2004, and Julie N. Shamburger, effective February 25, 2021. The agreements provide that the Bank will be the owner and beneficiary of Bank Owned Life Insurance (commonly referred to as BOLI) insuring the executives' lives and provide the executives the right to designate the beneficiaries of the death benefits guaranteed in the agreement. Mr. Gibson's agreement originally provided for death benefits in an aggregate amount of $700,000, and Ms. Shamburger's agreement originally provided for death benefits of $1.2 million. In both agreements, the amount is increased annually on the anniversary date of the agreement by an inflation adjustment factor of 5%. The agreement also states that after the executives' retirement date, the Company will pay an annual gross-up bonus to the executives in an amount sufficient to enable the executive to pay federal income tax on both the economic benefit and on the gross-up bonus itself.

As of December 31, 2023, the expected death benefits for Mr. Gibson and Mr. Shamburger totaled $1.8 million and $1.4 million, respectively, under these agreements. There was approximately $95,000 of benefit associated with the post retirement liability for the year ended December 31, 2023.
