profits of the corporation.

of all unpaid accrued dividends thereon, without interest before any sum shall
be paid to or any assets distributed among the holders of the common shares.
After such payment to the holders of the preferred stock, the remaining assets
and funds of the corporation shall be divided among and paid to the holders of
the common shares in proportion to the respective holdings of such shares.
