TXM Retirement Savings Plan

The Texas Mutual Retirement Savings Plan (“Plan”) is designed to provide you
with a means of accumulating savings for your retirement. You can invest
these savings in a variety of mutual funds available through the Plan. The Plan
is qualified under the Internal Revenue Code.

Retirement savings plan summary
As a Texas Mutual employee, you will receive an employer contribution to
your retirement savings account in an amount equal to 4% of your eligible
compensation each pay period. You’ll receive an additional 4% contribution if
your compensation exceeds the Social Security Wage Base (the compensation
limit that is subject to Social Security taxes).

Texas Mutual also offers a generous match on your contributions to the Plan.
TXM will match 100% of each $1.00 you contribute, up to and including 6% of
your eligible compensation each pay period. Severance, car allowance,
rewards, and relocation expenses are types of compensation excluded from
the retirement contribution calculation.
You may elect to contribute from 1 to 75% of your eligible compensation each
pay period, subject to Plan and IRS limits. Your contribution can be made as a
pre-tax 401(k) deferral with tax-deferred investment growth and/or as an
after-tax Roth 401(k) deferral with the potential for tax free investment
growth.

Building ownership in your account
You have 100% vested ownership in your own contributions. The Plan
maintains a vesting schedule to determine your ownership in the employer
contribution and the employer matching contribution. You earn a vesting
credit equal to an additional 20% vested ownership in your employer
contributions for each year of service. A year of service is attained for each
calendar year in which you work at least 1,000 hours. You may earn only one
vesting credit per calendar year. The vesting percentage is 100% after five or
more years of service.
