PER CURIAM.

       Jerome R. Johnson pleaded guilty to conspiracy to distribute MDMA (ecstasy)
in violation of 21 U.S.C. § 841(a)(1) and was sentenced to seventy months of
imprisonment. In calculating the advisory guideline range, the district court1 included
a four-level enhancement under U.S. Sentencing Guidelines (U.S.S.G.) § 3B1.1(a)
based on Johnson's role as a leader or organizer in the conspiracy. Johnson appeals
contending the government breached the parties' plea agreement by advocating for the
role enhancement because the agreement said Johnson "may" be eligible for safety

        The Honorable Gary A. Fenner, United States District Judge for the Western
District of Missouri.
valve relief under U.S.S.G. § 2D1.1(b)(7) (2005), and application of a role
enhancement automatically negated safety valve relief. See U.S.S.G. § 5C1.2(a)(4)
(precluding safety valve relief when the defendant is "an organizer, leader, manager,
or supervisor of others in the offense"). The government argues it did not breach the
agreement, and moves to dismiss the appeal based upon an appeal waiver contained
in the plea agreement. We enforce the appeal waiver and dismiss the appeal.

       Johnson contends because the government agreed he "may" be eligible for
safety valve relief, the government was barred from advocating any position that
would negate the mere possibility represented by the word "may." The plea
agreement provided, however, "there are no agreements between the parties with
respect to any Sentencing Guidelines issues other than those specifically listed."
Johnson's role in the offense was not one of the guideline issues listed in the plea
agreement. With respect to non-listed issues, the plea agreement indicated "the parties
are free to advocate their respective positions at the sentencing hearing."

        As a consequence, we do not believe the plea agreement's mere use of the word
"may" can bear the weight Johnson asks us to assign to it. The plea agreement
indicated Johnson "may" be eligible for safety valve relief if he provided a truthful
statement pursuant to U.S.S.G. § 5C1.2(a)(5), but the government did not promise he
"will" be eligible by doing so. Use of the word "may" implicitly recognized Johnson
"may not" be eligible for safety valve relief even if he provided a truthful statement,
because provision of a truthful statement is just one of five conditions a defendant
must satisfy to obtain safety valve relief. See U.S.S.G. § 5C1.2(a) (setting forth five
separate conditions which must be met before a defendant is eligible for safety valve
relief). By using the word "may," the plea agreement does not create an obligation on
the part of the government, but merely sets forth a correct statement of the law, as was
done in other clauses of the same paragraph of the plea agreement (e.g., "[t]he Court
may impose a sentence that is either above or below the defendant's applicable
Guidelines range, provided the sentence imposed is not 'unreasonable.'").

                                          -2-
       An appeal waiver in a plea agreement does not bar an appeal of a sentence if
there is a breach of the agreement. United States v. Wilkerson, 

, 1084
n.2 (8th Cir. 1999). In the absence of a breach, however, we will enforce the appeal
waiver. See United States v. Greger, 

, 1081 (8th Cir. 1996) ("So long
as the sentence is not in conflict with the negotiated agreement, a knowing and
voluntary waiver of the right to appeal from a sentence will be enforced."). Because
the government did not breach the plea agreement by advocating for a role
enhancement, we enforce the appeal waiver and grant the government's motion to
dismiss.
