2                    UNITED STATES v. DAVENPORT
                             OPINION

PER CURIAM:

   Pursuant to a valid plea agreement, Clarence Davenport, a/k/a
"Sweets," pled guilty to conspiracy to distribute and possess with
intent to distribute marijuana, in violation of 21 U.S.C. § 846 (1994),
and received a seventy-month prison term. On appeal, he contends
that the district court erred by denying his motion for a downward
departure due to his numerous medical problems. Because Davenport
made a valid waiver of his right to appeal his sentence, we dismiss
the appeal.

   A defendant whose plea agreement contains an express waiver of
the right to appeal may not appeal his sentence unless the waiver is
shown to be unknowing or involuntary. United States v. Brown, 232
F.3d 399, 403 (4th Cir. 2000); see also United States v. Marin, 961
F.2d 493, 496 (4th Cir. 1992). Davenport’s plea agreement contained
such a waiver. Our review of the plea agreement and the record of the
plea colloquy reveal that Davenport’s waiver was knowing and volun-
tary. The sentence did not exceed the statutory maximum penalty and
there is no evidence that it was based on a constitutionally impermis-
sible factor. Marin, 961 F.2d at 496. Moreover, the sentence was not
imposed pursuant to proceedings conducted in violation of Daven-
port’s right to counsel. United States v. Attar, 38 F.3d 727, 732-33
(4th Cir. 1994).

  We therefore dismiss the appeal for lack of jurisdiction. We dis-
pense with oral argument because the facts and legal contentions are
adequately presented in the materials before the court and argument
would not aid the decisional process.

                                                          DISMISSED
