The appellants contend that the transaction had gone so far, when the first agreement as to the stock division had been reached, that the incorporators could not legally substitute the agreement as to the issuance of both notes and stock. They strongly rely upon the case of McGaw v. Hoen, 133 Md. 672, 106 A. 13. In that case promoters conveyed property to a corporation in return for stock. Subsequently, certificates of indebtedness were issued to some of the promoters to the full amount in value of their interests in the property conveyed.
