Kernrechtsfrage
Whether the framework contract was validly terminated for important reasons under the contract and general law
Extrahierter Entscheid
The contract was not validly terminated for important reasons; the March 2009 termination was ineffective.
Extrahierte Begründung
The proven breaches of the exclusivity clause were mostly minor, did not amount to work mutilation, and did not make continuation of the long-term relationship objectively intolerable after balancing the parties' interests.
