An establishment shall enter into a contract with the secretary in which in return for incentive payments authorized pursuant to Kan. Stat. Ann. § 74-8943, and amendments thereto, the establishment agrees that, in the event that insufficient revenue is realized by the payments made pursuant to Kan. Stat. Ann. § 74-8943, and amendments thereto, the establishment shall be responsible for the debt services on obligations issued pursuant to this act. The contract shall include a specified amount which the establishment agrees to invest in the state and shall be the basis for determining the amount of obligations issued pursuant to Kan. Stat. Ann. § 74-8943, and amendments thereto. In the event the establishment invests a lesser amount the establishment shall repay any amount received at a ratio of $1 for each $5 of the difference between the amount pledged and the amount actually invested. The contract shall further specify that, in the event the rate of taxation set forth in the Kansas income tax act is abolished and insufficient revenue is realized to meet the debt service on the obligations issued pursuant to this act, the establishment shall not be responsible for any amount of shortfall attributable to such reduction in rates. The contract may specify such additional terms and conditions as may be necessary to administer this act. The secretary may include provisions in the contract to reduce the amount of eligible tax credits or other benefits on the investment to support such bond repayment.
