When two or more corporations are merged or consolidated, as provided by this act, the single corporation shall have power and authority to issue bonds or other obligations, negotiable or otherwise, and with or without coupons or interest certificates attached, to an amount sufficient to provide for all the payments it will be required to make, or obligations it will be required to assume, in order either to effect such merger or consolidation or thereafter to conduct the enterprise for which it was organized. To secure the payments of such bonds and obligations it shall be lawful to mortgage its corporate franchises, rights, privileges and property, real, personal and mixed, and it shall be lawful to issue certificates of membership or other evidence of interest to such extent as may be necessary to the members of such constituent corporations in exchange or payment for the original memberships or units of interest in the manner and on the terms specified in the resolution of merger or consolidation.
