Section 43. Subscriptions to the capital stock of a corporation shall be paid at such times and in such installments as the board of directors may by resolution require. If default shall be made in the payment of any installment as required by such resolution, the board may declare the stock and all previous payments thereon forfeited for the use of the corporation, after the expiration of sixty days from the service on the defaulting stockholder, personally or by mail directed to him at his last-known post-office address, of a written notice requiring him to make payment within sixty days from the service of the notice at a place specified therein, and stating that, in case of failure to do so, his stock and all previous payments thereon will be forfeited for the use of the corporation. Such stock, if forfeited, may be reissued, or subscriptions therefor may be received as in the case of stock not issued or subscribed for. If not sold for its par value or subscribed for within six months after such forfeiture, it shall be canceled and deducted from the amount of the capital stock. If by such cancellation, the amount of the capital stock is reduced below the minimum required by law, the capital stock shall be increased to the required amount within three months thereafter or an action may be brought or proceedings instituted to close up the business of the corporation as in the case of an insolvent corporation. If a receiver of the assets of the corporation has been appointed, all unpaid subscriptions to the stock shall be paid at such times and in such installments as the receiver or the court may direct.

Section 44. Any domestic corporation may increase or reduce its capital stock in the manner herein provided, but not above the maximum or below the minimum, if any, prescribed by law. If increased, the holders of the additional stock issued shall be subject to the same liabilities with respect thereto as are provided by law in relation to the original capital; if reduced, the amount of its debts and liabilities shall not exceed the amount of its reduced capital, unless an insurance corporation, in which case the amount of its debts and liabilities shall not exceed the amount of its reduced capital and other assets. The owner of any stock shall not be relieved from any liability existing prior to the reduction of the capital stock of any corporation. If a banking corporation, whether capital be increased or reduced, its assets shall at least be equal to its debts and liabilities and capital stock as increased or reduced.

Section 47. Every domestic stock corporation may have preferred and common stock, and different classes of preferred stock, if the certificate of incorporation so provides or by the unanimous consent of the stockholders, and may, upon the written request of the holder of any preferred stock, by a two-thirds vote of its directors, exchange the same for common stock, and issue certificates for common stock therefor, share for share, or upon such other valuation as may have been agreed upon in the scheme for the organization of such corporation, or the issue of such preferred stock, but the total amount of such capital stock shall not be increased thereby.

Section 54. The stockholders of every stock corporation shall, jointly and severally, be personally liable to its creditors, to an amount equal to the amount of the stock held by them respectively, for every debt of the corporation, until the whole amount of its capital stock issued and outstanding at the time such debt was incurred shall have been fully paid. The stockholders of every stock corporation shall jointly and severally be personally liable for all debts due and owing to any of its laborers, servants or employes other than contractors, for services performed by them for such corporation. Before such laborer, servant or employe shall charge such stockholder for such services, he shall give him notice in writing, within thirty days after the termination of such services that he intends to hold him liable and shall commence an action therefor within thirty days after the return of an execution unsatisfied against the corporation upon a judgment recovered against it for services. No person holding stock in any corporation as collateral security, or as executor, administrator, guardian or trustee, unless he shall have voluntarily invested the trust funds in such stock, shall be personally subject to liability as a stockholder; but the person pledging such stock shall be considered the holder thereof, and shall be liable as stockholder; and the estates and funds in the hands of such executor, administrator, guardian, or trustee shall be liable in the like manner and to the same extent as the testator or intestate, or the ward, or person interested in such trust fund would have been, if he had been living and competent to act and held the same stock in his own name, unless it appears that such executor, administrator, guardian, or trustee voluntarily invested the trust funds in such stocks, in which case he shall be personally liable as a stockholder.

Section 55. No action shall be brought against a stockholder for any debt of the corporation until judgment therefor has been recovered against the corporation, and an execution thereon has been returned unsatisfied in whole or in part, and the amount due on such execution shall be the amount recoverable, with costs against the stockholder. No stockholder shall be personally liable for any debt of the corporation not payable within two years from the time it is contracted, nor unless an action for its collection shall be brought against the corporation within two years after the debt becomes due; and no action shall be brought against a stockholder after he shall have ceased to be a stockholder, for any debt of the corporation, unless brought within two years from the time he shall have ceased to be a stockholder.
