Defendants below1 appeal from the trial court’s grant of a preliminary injunction to plaintiffs DaVita, Inc. and its subsidiary, Renal Treatment Centers-Mid-Atlantic, Inc., in their action seeking monetary damages as well as injunctive relief in this dispute regarding dialysis centers in Macon, Perry, and Hawkinsville, and noncompete agreements signed by Dr. and Mrs. Martinez. The trial court made the following findings of fact. Dr. Martinez is a nephrologist practicing in the Macon and surrounding areas, specializing in treatment of kidney disease. In 1993, Mrs. Martinez and Vickie Jackson, a friend, purchased an interest in Nephrology Center of Macon, Inc. from Stockton. Mrs. Martinez acknowledged that Dr. Martinez gave her $50,000, which was the amount she invested in her purchase of Nephrology Center of Macon, Inc. After Stockton was fired, Mrs. Martinez and Jackson purchased his interest, with Mrs. Martinez owning 60 percent of the business and Jackson owning 40 percent. The corporate business name was changed to Kidney Care, Inc. hereinafter referred to as the “East Macon facility”. Mrs. Martinez was the administrator of the facility and Jackson was the nurse administrator. Dr. Martinez, before and after the change of ownership, was the Medical Director of this facility and was, at that time, the only physician referring patients to it. Prior to making her investment, Mrs. Martinez spoke with Dr. Martinez to insure he would remain Medical Director of the facility upon their purchasing it.
On August 27, 1997, Mrs. Martinez and Jackson, through Kidney Care, Inc., sold the East Macon facility to Renal Treatment Centers —Mid-Atlantic, Inc., a subsidiary of DaVita, Inc. hereinafter “DaVita” for $4.25 million, as set out in the Asset Purchase Agreement. Mrs. Martinez acknowledged that her portion of the purchase price went into a joint account with Dr. Martinez. As part of the sale, that same day, Mrs. Martinez signed a covenant not to compete prohibiting her, along with Kidney Care, Inc. and Jackson, from being directly or indirectly involved with any dialysis facility within a 40-mile radius of the East Macon facility for ten years. Also signed that day by Dr. Martinez was the Medical Director Agreement between him and DaVita for the East Macon facility. Execution of the Asset Purchase Agreement was expressly conditioned upon Dr. Martinez’s execution of this Medical Director Agreement, and the Medical Director Agreement was contingent upon execution of the Asset Purchase Agreement.
