CRITICAL — KLEIN, THORPE & JENKINS DUAL REPRESENTATION: KTJ attorney Dennis Walsh simultaneously served as Village Attorney for Orland Park (drafting TIF ordinances) and represented Orland SD 135 and CHSD 230 on school law matters — the same school districts that lost property tax revenue to those TIFs. KTJ is now issuing opinion letters claiming the school payment agreements it originally drafted are unenforceable. Applies: 50 ILCS 105/3 • 65 ILCS 5/11-74.4-5(d) • Illinois Rules of Professional Conduct 1.7, 1.9

KTJ drafted original ordinance. KTJ now says school payment agreement is illegal.
