The plaintiff company (lessor) leased subdivision D of Derbyshire Farm to the defendants (husband and wife lessees) under a written lease agreement executed on 12 January 2000 for 3 years (1 January 2000 to 31 December 2003), renewable for 2 years at the lessee's option. The lease included an option to purchase the farm at clause 15. The farm was previously used as a quarry and tombstone production site, with three sheds and an office building. The defendants moved onto the farm with livestock and farming implements, grew maize, renovated sheds into poultry runs and pigsties, constructed workers' houses and ablution facilities, and eventually operated a piggery with 1000 pigs. The defendants made extensive improvements to the property. Purchase negotiations occurred from June 2005 to January 2006, with prices escalating from $200 million to $400 million (old currency), but no sale agreement was concluded. In March 2006, Misheck Mataranyika acquired 7418 shares in the plaintiff company for $700 million, becoming the majority shareholder. When negotiations between Mataranyika and the defendants failed, the plaintiff sought eviction. The defendants paid rentals regularly until March 2006, but subsequent payments (April-December 2006 and all of 2007) were made without prejudice and late.
