The consideration for the issuance of shares may be paid, in whole or in part, in money, in other property, tangible or intangible, or in labor or services actually performed for the corporation. When payment of the consideration for which shares are to be issued shall have been received by the corporation, such shares shall be deemed to be full paid and non-assessable. In the absence of actual fraud in the transaction, and subject to the provisions of Section 8.60, the judgment of the board of directors or the shareholders, as the case may be, as to the value of the consideration received for shares shall be conclusive.
