A contract to pay a broker a commission upon the rent under the renewal of a lease, if the tenant exercised his option to renew, does not entitle the broker to the commission where the tenant failed to exercise his option within the time required, but later took a new lease with different provisions. Allium Realty Co. v. Barth, 146 N. Y. Sup. 960, 161 App. Div. 568.
