Amend CSHB 2039 (Senate committee report) by striking SECTION 2 of the bill (page 2, lines 34-43), and substituting the following: SECTION 2. Sections 271.152, 251.153, and 251.154, as added by this Act, apply to a claim that arises under a contract executed before the effective date of this Act only if sovereign immunity has not been waived with respect to the claim before the effective date of this Act. A claim that arises under a contract executed before the effective date of this Act and with respect to which sovereign immunity has been waived is governed by the law in effect on the date the contract was executed, and the former law is continued in effect for that purpose.
