A corporation may apply to the Secretary of State for authorization to use a name that is not distinguishable upon his records from one or more of the names described in subsection (b). The Secretary of State shall authorize use of the name applied for if:
The other corporation consents to the use in writing and submits an undertaking in form satisfactory to the Secretary of State to change its name to a name that is distinguishable upon the records of the Secretary of State from the name of the applying corporation; or
The applicant delivers to the Secretary of State a certified copy of the final judgment of a court of competent jurisdiction establishing the applicant's right to use the name applied for in this state.
A corporation may use the name (including the fictitious name) of another domestic or foreign corporation that is used in this state if the other corporation is incorporated or authorized to transact business in this state and the proposed user corporation:
Has merged with the other corporation;
Has been formed by reorganization of the other corporation; or
Has acquired all or substantially all of the assets, including the corporate name, of the other corporation.
