No such amendment which has the effect of increasing Plan liabilities by reason of increases in benefits, establishment of new benefits, changing the rate of benefit accrual, or changing the rate at which benefits become nonforfeitable may take effect during any Plan Year if the Plan’s AFTAP for such Plan Year is less than 80% (or

would be less than 80% taking into account such amendment); provided that (a) this Section 16.1 shall cease to apply to any Plan Year, effective as of the first day of such Plan Year, upon payment by the Employer of a contribution (in addition to any minimum required contribution under Code Section 430) equal to the amount of the increase in the Plan’s funding target under Code Section 430 for the Plan Year attributable to the amendment (or sufficient to result in an AFTAP of 80%), and (b) this sentence shall not apply to any amendment which provides for an increase in benefits under a formula which is not based on a Participant’s compensation, but only if the rate of such increase is not in excess of the contemporaneous rate of increase in average wages of Participants covered by the amendment.

For years beginning after December 31, 2008, an individual on a qualified military leave who is receiving differential wage payments (as defined by Code Section 3401(h)(2)) from the Employer, shall be treated as an Employee of the Employer. Such differential wage payment shall be treated as Compensation and the Plan shall not be treated as failing to meet the requirements of any provision described in Code Section 414(u)(1)(c) by reason of any contribution or benefit which is based on the differential wage payment. Notwithstanding any provision of this Section 17.10 to the contrary, if the inclusion of differential wage payments in a Participant’s Compensation reduces a Participant’s Accrued Benefit under the Plan such differential wage payments shall be ignored for determining the Participant’s Accrued Benefit.

          Section 9. Effect of Amendments. Except as amended and modified by this Amendment, the Existing Plan shall continue in full force and effect. The Existing Plan and this Amendment shall be read, taken and construed as one and the same instrument. This Amendment shall supersede any provisions of the Existing Plan to the extent those provisions are inconsistent with the provisions of this Amendment. Upon the effectiveness of this Amendment, each reference in the Existing Plan to “this Plan” or “the Plan” shall mean and be a reference to the Existing Plan as amended hereby.

          Section 12. Governing Law. To The Extent Not Superseded By The Laws Of The United States, This Amendment Shall Be Construed and Enforced in Accordance With, and the Rights of the Parties Shall Be Governed By, the Internal Laws of the State of Texas, Without Reference to Principles of Conflicts of Law.
