(a) In an action to enforce a secondary right brought by one or more stockholders or members of a corporation or similar entity because the corporation or entity refuses or fails to enforce rights which could be asserted by it, the complaint shall set forth
(1) that each plaintiff is a stockholder or owner of an interest in the corporation or other entity,(2) the efforts made to secure enforcement by the corporation or similar entity or the reason for not making any such efforts, and(3) either
(i) that each plaintiff was a stockholder or owner of an interest in the corporation or other entity at the time of the transaction of which the plaintiff complains or that the plaintiff’s stock or interest devolved upon the plaintiff by operation of law from a person who was a stockholder or owner at that time, or(ii) that there is a strong prima facie case in favor of the claim asserted on behalf of the corporation and that without the action serious injustice will result.
