Ordered that the sentence is affirmed.
The record is insufficient to demonstrate that the defendant knowingly, voluntarily, and intelligently waived his right to appeal ( see People v David S., 78 AD3d 1205; People v Shoman, 74 AD3d 843; People v Gladden, 267 AD2d 400; People v Dongo, 244 AD2d 353). Accordingly, the defendant's purported waiver of his right to appeal does not preclude review of his contention that the Supreme Court should have afforded him youthful offender treatment. However, contrary to the defendant's contention, the Supreme Court providently exercised its discretion in denying his request for youthful offender treatment considering, inter alia, the serious nature of the offense he committed, and the otherwise favorable plea agreement ( see People v Huffman, 47 AD3d 646; People v Wright, 44 AD3d 692; People v Thompson, 16 AD3d 603; cf. People v Cruickshank, 105 AD2d 325, aff'd sub nom. People v Dawn Maria G, 67 NY2d 625).
