It is undisputed that appellant Greco has appeared for deposition and provided the information sought from her as well as regarding her co-appellant, rendering the appeal moot ( see Matter of McMahon v Landon, 154 AD2d 745). Appellants have failed adequately to explain how the circumstances fall within an exception to the mootness doctrine ( see Matter of Hearst Corp. v Clyne, 50 NY2d 707, 714-715).
