(b) The board of directors may determine the payment terms of subscription for shares that were entered into before incorporation, unless the subscription agreement specifies them. A call for payment by the board of directors must be uniform so far as practicable as to all shares of the same class or series unless the subscription agreement specifies otherwise.
(c) Shares issued pursuant to subscriptions entered into before incorporation are fully paid and nonassessable when the corporation receives the consideration specified in the subscription agreement.
(d) If a subscriber defaults in payment of money or property under a subscription agreement entered into before incorporation, the corporation may collect the amount owed as any other debt. Alternatively, unless the subscription agreement provides otherwise, the corporation may rescind the agreement and may sell the shares if the debt remains unpaid for more than twenty days after the corporation sends written demand for payment to the subscriber.
(e) A subscription agreement entered into after incorporation is a contract between the subscriber and the corporation subject to section six hundred twenty-one of this article.
