I. Appellees were not entitled to summary judgment on Frisco Summits’ breach-of-fiduciary-duty, aiding-and-abetting, and conspiracy claims. ................................................................................ 32 A. No-evidence grounds ................................................................ 32 B. Traditional grounds ................................................................. 43 C. Because Frisco Summit’s breach-of-fiduciary-duty claims survive summary judgment, so do its conspiracy and aiding-andabetting claims. ................................................................................ 52 II. The trial court’s rulings on the time for performance under the JVA and LPA are legally and factually erroneous.............................. 53 A. The record evidence and the trial court’s findings of fact and conclusions of law regarding the Appellees’ obligations to develop the Property ............................................................................................ 53 B. The Trial Court erred in failing to imply a reasonable time for performance of the LPA. .................................................................. 56 III. The trial court erred by failing to make the findings of fact and conclusions of law necessary to support its take-nothing judgment on Frisco Summit’s claim for breach of the JVA...................................... 59 IV. Because the LPA is a partially integrated contract between different parties, it did not extinguish the JVA. ................................. 64 A. The LPA is not “fully” integrated. ........................................... 66 B. The merger doctrine does not foreclose Frisco Summit’s claims regarding timely development of the Property under the JVA....... 69 C. The JVA is both collateral to and consistent with the LPA. ... 71 V. The trial court’s finding that Frisco Multifamily GP did not breach §7.01(d)(ii) of the LPA is clearly erroneous. ............................ 74 VI. Newly discovered evidence provided good cause for leave to amend and the trial court abused its discretion in denying it. .......... 75 VII. This Court should reverse and remand Appellees’ Attorney’s Fees Award. ......................................................................................... 78 PRAYER .................................................................................................. 79 CERTIFICATE OF COMPLIANCE ........................................................ 81 CERTIFICATE SERVICE ....................................................................... 81
