MEMORANDUM **

Adan Lopez Crespo appeals from the district court’s judgment and challenges his guilty-plea conviction and 102-month sentence for conspiracy to manufacture at least 1,000 marijuana plants, in violation of 21 U.S.C. § 846. Pursuant to Anders v. *552 California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), Lopez Crespo’s counsel has filed a brief stating that there are no grounds for relief, along with a motion to withdraw as counsel of record. Lopez Crespo has filed a pro se supplemental brief, and the government has filed an answering brief.

Lopez Crespo has waived his right to appeal his conviction and sentence. Our independent review of the record pursuant to Penson v. Ohio, 488 U.S. 75, 80, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), discloses no arguable issue as to the validity of the waiver. See United States v. Watson, 582 F.3d 974, 986-88 (9th Cir. 2009). We accordingly dismiss the appeal. See id. at 988.

Counsel’s motion to withdraw is GRANTED.

DISMISSED.
