Where plaintiff alleged that defendant agreed to pay him $1,000,000 for information and services relating to the prospective purchase of a railroad, in case the defendant purchased the same or became interested in its purchase with others, such contract could not be construed to restrain defendant from becoming interested in the purchase of such railroad for all time, on pain of being liable on the contract, but only bound him not to participate in the purchase for a reasonable time unless he paid plaintiff for his services.
