Exceptions overruled. In this action of contract, which was tried to a judge, the sole evidence introduced was a written contract which, it was agreed, was executed by the parties. In the contract the plaintiff agreed with the defendant corporation to sell to it sixty-four shares of common stock for $10,000; one Kardon in the same agreement likewise agreed with the defendant to sell to it thirty-two shares of common stock for $5,000. To secure payment both the plaintiff and Kardon deposited their stock in escrow with a trustee. The plaintiff brings this action to recover an unpaid balance of $2,100. The judge found for the plaintiff. The questions presented arise from the defendant’s exceptions to the action of the judge *777with respect to certain requests for rulings. There was no error. The judge rightly ruled that the plaintiff was not a joint obligee and could sue without joining Kardon. And he rightly ruled that the action did not have to be brought by the trustee named in the escrow agreement.
