(a) Whether or not the applicant possesses the good moral character which would entitle him to be admitted to the Oklahoma Bar Association;

(b) Whether or not the applicant has engaged in any unauthorized practice of law during the period of suspension, disbarment or resignation;

(c) Whether or not the applicant possesses the competency and learning in the law required for admission to practice law in the State of Oklahoma, except that any applicant whose membership in the Association has been suspended or terminated for a period of five (5) years or longer, or who has been disbarred, shall be required to take and successfully pass the regular examination given by the Board of Bar Examiners of the Oklahoma Bar Association. Provided, however, before the applicant shall be required to take and pass the bar examination, he shall have a reasonable opportunity to show by clear and convincing evidence that, notwithstanding his long absence from the practice of law, he has continued to study and thus has kept himself informed as to current developments in the law sufficient to maintain his competency. If the Trial Panel finds that such evidence is insufficient to establish the applicant's competency and learning in the law, it must require the applicant to take and pass the regular bar examination before a finding as to his qualifications shall be made in his favor.
