A new lease executed by a landlord to a different corporation; held, not the exercise of an option to renew contained in a former lease, and hence plaintiff, a broker, who procured the latter and was entitled to a portion of the rent thereunder, could not recover any portion of the rent accruing under the new lease, in the absence of any claim of fraud. Collum v. Boos Bros., 142 P. 858, 25 Cal. App. 73.
