There is no merit in the defense to this action. It is purely technical and should not be permitted to prevail unless the law clearly commands it. The plaintiff, by a contract in writing signed by himself and the defendant company, by its treasurer, and to which its seal was attached, purchased of the defendant 200 shares of its capital stock at $25 per share, and there was a stipulation in the contract that the defendant would furnish plaintiff a buyer for the stock within six months, if desired, at a price to net the plaintiff a profit of $2.50 per share. The plaintiff gave his note'for the stock, which was paid at maturity, and the money went into the treasury of the company. The stock remained in its custody. The defendant, at the expiration of six months and on request of plaintiff, declined or neglected- to furnish him with a' purchaser for his stock in accordance with the agreement between the parties, and this shit was brought to recover damages for the breach of the contract. The jury returned a verdict for the plaintiff, and the court below directed judgment to be entered thereon.

It is not denied by the defendant company that the treasurer was empowered to contract for the sale of the stock to the plaintiff, but it contends that the part of the contract which relates to procuring a purchaser for the stock is invalid. It is claimed that the treasurer was without authority to make this part of the agreement; that it was ultra vires; and that the contract was divisible, the sale of the capital stock being valid and enforceable and the agreement to furnish a purchaser for the stock, if the plaintiff desired to sell within six months, was separate and collateral to the other part of the agreement. It will be observed that the two parts of the agreement are in one and the same instrument of writing *32which was signed by the parties and the seal of the defendant affixed but once. The contract was clearly entire and indivisible. Such was the manifest purpose of the parties. It would.be wholly without reason, under the circumstances of the case, to suppose that the plaintiff intended to enter into two contracts, one by which the defendant sold the stock to the plaintiff and another, a separate agreement, by which the plaintiff was to be protected in case the stock proved to be valueless or not above par at-the end of the six months, which manifestly was the inducement for plaintiff to make the investment. The contract on its face shows that the defendant was quite willing and felt justified in agreeing to furnish a purchaser for the plaintiff’s stock at the increased price, as it declares the Automobile Supplies Company had sold the. whole output of its plant, thereby insuring the success of the business. It is to be noted that the plaintiff avers in his affidavit of claim that he was induced by the provision in question to enter into the contract for the purchase of stock, and the averment is not denied in the affidavit of defense. .The provision for furnishing to the plaintiff a customer for his stock was, therefore, an inducement for the plaintiff to agree to purchase the stock and, hence, was part of the consideration for plaintiff to make the purchase.

We think the contract to procure a purchaser was not ultra vires. The sale was not made to plaintiff as" an original incorporator but of undisposed stock remaining in the treasury. The learned court below has cited many authorities which sustain this position.

We also concur with the trial court that the defendant is estopped to plead ultra vires as a defense in this action. As observed above, it is not alleged that the treasurer did not have authority to contract in behalf of the corporation for the sale of the stock and receive payment therefor, and the only denial of his authority is that he could not bind the corporation to furnish a purchaser for the plaintiff’s stock, but, as already pointed out, he en*33tered into a contract which is entire and indivisible for the sale of the stock and to procure a purchaser therefor for the plaintiff within a specified time. He received the five thousand dollars, the full consideration for the stock, and it went into and is still retained in the treasury of the company without any offer by the company to return it to the plaintiff although the defendant has refused to perform the other part of its contract. There has been complete and perfect performance of the contract by the plaintiff, of which the defendant company has received and still retains the benefit. It is, therefore, not in a position and will not be permitted to deny either the authority of its agent in negotiating the contract or its liability to comply with its terms. Such is the settled doctrine of this court as announced in a long line of decisions, one of the inore recent of which is Presbyterian Board v. Gilbee, 212 Pa. 310, where it is said (p. 314): “It is repugnant to every sense of justice and fair dealing that a principal shall avail himself of the benefits of an agent’s act, and at the same time repudiate his authority. A corporation may not avail itself even of ultra vires as a defense where a contract has been entered, into and executed in good faith by the other party and the corporation has received the benefit of the performance.”

Judgment affirmed.
