ORDER AND JUDGMENT *

After examining the briefs and appellate record, this panel has determined unani *883 mously to grant the parties’ request for a decision on the briefs without oral argument. See Fed. R.App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument.

Defendant-appellant Derrick Jermaine London pled guilty to one count of conspiracy to possess with intent to distribute and to distribute cocaine and cocaine base (crack) in violation of 21 U.S.C. § 841(a)(1). Defendant was sentenced to life imprisonment and, if released, to a term of five years supervised release. Defendant now appeals his sentence.

The government has moved to dismiss the appeal for lack of subject matter jurisdiction, citing defendant’s waiver of his right to appeal in the plea agreement. In the plea agreement, defendant agreed to waive his right to appeal or collaterally challenge his “sentence as imposed by the Court and the manner in which the sentence is determined, provided the sentence is within or below the applicable guideline range determined by the Court to apply to this case....” Appellant’s App. Vol. I at 47-48. Defendant specifically reserved the right to appeal in the event the court departed upward. See id. at 48. Defendant’s sentence, however, was within the applicable guideline range and no upward departure was applied.

“This court will hold a defendant to the terms of a lawful plea agreement. A defendant’s knowing and voluntary waiver of the statutory right to appeal his sentence is generally enforceable.” United States v. Atterberry, 144 F.3d 1299, 1300 (10th Cir. 1998) (citation and quotation omitted). Our review of the plea agreement and the transcripts of the sentencing hearings reveals nothing to suggest that defendant’s waiver was either unknowing or involuntary, or that defendant was unaware of the consequences of his plea.

The appeal is DISMISSED.
