If Non-IP partner failed to work "full time" for his 50% equity, as called for, does that nullify the parnership agreement?

Parnership agreement calls for 1 partner to put his IP in to the Entity, and to work part time (while working full time for a corporation) in selling and delivering services derived from the IP. Other partner was to work dilligently full time in marketing, commercializing and selling the services. IP partner generated 100% of sales while working part time, none from any entity marketing efforts. Non IP parnter failed to work full time and produced no sales, and no marketing although he did recieve half of the revnue generated by IP parnter. Does non-IP partner lose his equity for failure to perform per the agreement? Can the partnership be dissoved based on this failure? - Is this your question? Add additional information
