1. At any time 1 or more natural persons, corporations or partnerships may incorporate a redevelopment corporation on making, subscribing, acknowledging and filing in the corporation and securities commission a certificate pursuant to the general corporation law, which shall be entitled and endorsed "certificate of incorporation of ............ redevelopment corporation, pursuant to the general corporation law," the blank space being filled in with the remainder of the name of the corporation. Such certificate shall contain the provisions required in, and may contain any provisions consistent with the provisions of this act permitted in, a certificate of incorporation filed pursuant to the general corporation law, except that:

    (a) Included among the purposes for which the corporation is formed shall be the formulation, obtaining the approval of, and putting into effect of a development plan, the acquisition of real property in a development area, and the construction, maintenance and operation of a development pursuant to this act;

    (b) The duration of the corporation shall not be less than 20 years;

    (c) The certificate may provide for the issuance of income debentures, in which case the holders of such debentures may be allowed such voting rights as shall be specified therein;

    (d) The certificate may provide that the corporation shall have the power to cooperate with and participate in any programs of the federal or state governments which have been or may be enacted for purposes of the development or redevelopment of areas of cities which are substandard, insanitary, polluted or neglected.

    (e) The certificate may provide that the corporation shall have the power to guarantee, purchase, hold, sell, assign, transfer, mortgage, pledge or otherwise dispose of any bonds, securities or evidence of indebtedness created by any person or other legal entity related to properties or businesses located in the redevelopment area.

    (f) The certificate shall contain a declaration that the redevelopment corporation has been organized to serve a public purpose, and that it shall be subject to supervision and control as provided in this act. A copy of such certificate shall be filed with the planning commission and the supervising agency having jurisdiction within 10 days of its being filed in the corporation and securities commission.

    2. At any time any domestic corporation which is not a redevelopment corporation, but which has been incorporated pursuant to the general corporation law may become a redevelopment corporation by filing an appropriate certificate or certificates pursuant to the general corporation law changing the provisions of its certificate of incorporation to eliminate any provisions therein inconsistent with the provisions of this act and adding or substituting the provisions required by this section by changing its name to a name corresponding to the form ".......................... redevelopment corporation," and making all the other changes necessary to enable it to conform with all of the provisions of this act. Any such certificate shall be prepared and filed pursuant to the general corporation law, except that in addition to citing such law in the title of such certificate, the title shall also state that it is being made pursuant to section 6.

    3. If a redevelopment corporation shall not have obtained the certificates of approval of its development plan required by section 4 within 12 months of the date upon which it became a redevelopment corporation, or shall not substantially comply with the development plan within the time limit for the completion of each stage thereof as therein stated, reasonable delays caused by unforeseen difficulties excepted, then upon the filing in the department of state of a certified copy of the order of the court establishing such failure to obtain such certificate or substantially so to comply, obtained pursuant to section 14, such redevelopment corporation shall cease to have the special rights, powers and privileges granted to, or be subject to the special duties, liabilities and restrictions imposed upon, a redevelopment corporation by this act, and shall thereafter change its name to remove the word "redevelopment" therefrom. In such event, however, such corporation may thereafter continue in existence as a corporation, subject to the general corporation law. In the event that a certified copy of such order shall be so filed, all real property acquired by or for such redevelopment corporation by condemnation shall be disposed of, either alone or in conjunction with additional real property not so acquired, within a reasonable time by bona fide sale conducted in such a manner as may be prescribed by ordinance of the local legislative body. All amounts received by the redevelopment corporation for such real property in excess of an amount equal to that portion of the development cost allocable to the real property being disposed of, shall be paid to the city.

    4. No corporation now organized under the laws of the state shall change its name to a name, and no such corporation hereafter organized shall have a name, containing the word "redevelopment" as a part thereof, unless and until such corporation is or becomes a redevelopment corporation. No foreign corporation now authorized to do business in the state shall change its name to a name, and no such corporation shall hereafter be authorized to do business in the state with a name, containing the word "redevelopment" as a part thereof.
