OPINION
Defendant-appellant Rhonda D. Fitch appeals from the sentence of the district court which committed her to 121 months imprisonment upon her guilty plea to various charges arising out of her participation in an illegal drug-trafficking and money laundering scheme. Fitch alleges that the terms of her plea agreement precluded the government’s recommendation that she receive a four-level sentence enhancement for her role in the offense under Sentencing Guidelines § 3B1.1. Fitch also contends that she was sentenced in violation of
Apprendi v. New Jersey,
I. BACKGROUND
On April 29, 1999, a federal grand jury returned a superseding indictment charging Fitch with conspiracy to possess with intent to distribute marijuana and cocaine, *366 aiding and abetting the possession of marijuana with intent to distribute, and attempting to possess marijuana with intent to distribute. Fitch was arraigned on May 6, and entered a plea of not guilty. On September 10, 1999, Fitch was also charged by Information with conspiracy to commit money laundering. To this charge, she pleaded guilty. Fitch also changed her plea to guilty as to the charges in the indictment. On that same day, Fitch and the government also entered into a written plea agreement.
Paragraph two of the agreement provided that the government would agree to recommend that “the defendant’s base offense level be calculated using 1000 pounds of marijuana and 1 kilogram of cocaine and that no other relevant conduct be used to increase the defendant’s base offense level.” J.A. at 36. On September 13, the district court entered orders reflecting the guilty pleas as to the charges in the indictment and Information. On December 22, 1999, Fitch was charged by Information with one count of money laundering. The next day she pled guilty to that charge as well.
The defendant’s sentencing hearing was held on August 25, 2000. At sentencing, the government requested that Fitch receive a four-point enhancement for her role in the offense as an organizer and leader under Sentencing Guidelines § 3131.1(a). 1 Fitch did not dispute that she was in fact an organizer and leader of criminal activity. Fitch claimed instead that she understood the plea agreement to mean that no conduct other than the quantity of drugs specified in the plea agreement would be used to increase her sen-fence. The district court, however, agreed with the government that the plea agreement dealt only with the amount of marijuana and cocaine that would be used to calculate the defendant’s base offense level, and that nothing in the agreement prevented the application of § 3B1.1. Thereafter, the charges were grouped pursuant to Sentencing Guidelines § 3D1.2(b)-(c) and Fitch was sentenced for violations of 21 U.S.C. §§ 841, 846 and 18 U.S.C. § 1956 to 121 months imprisonment followed by four years of supervised release.
II. DISCUSSION
The resolution of this appeal turns on the interpretation of the defendant’s plea agreement. Because “[p]lea agreements are contractual in nature,”
United States v. Robison,
We believe that the defendant’s sentence cannot stand in light of a material ambiguity in the plea agreement. The provision at issue states, “[t]he government agrees to *367 recommend that the defendant’s base offense level be calculated using 1000 pounds of marijuana and 1 kilogram of cocaine and that no other relevant conduct be used to increase the defendant’s base offense level.” Fitch argued at sentencing that according to the plea agreement nothing-including her leadership role in the offense-would be used to enhance her sentence. The government argued before the district court, as it argues here, that the defendant’s reading of the plea agreement is strained. The government contends that the disputed language relates solely to the amount of marijuana and cocaine that would be used to calculate the defendant’s base offense level, and that the agreement did not preclude the government from requesting an upward adjustment under § 3B1.1.
The crux of the government’s argument, accepted by the district court, is that “base offense level” is a term with a technical meaning under the Sentencing Guidelines. While the defendant’s base offense level is the starting point in the sentencing computation, “base offense level” is a term of art separate and distinct from the subsequent adjustments or enhancements that are applied in light of the specific offense characteristics or special factors under Chapter Three of the Sentencing Guidelines. The following exchange occurred during the sentencing hearing:
MR. O’BRIEN [for the government]: The base offense level is exactly what it says. It is the base offense level.
THE COURT: It is. It is a term that is defined in our process.
MR. O’BRIEN: Right.
THE COURT: It is also defined — well, it also has a particular entry point on our — in our report. Base offense level, paragraph 30 of the — it’s not the same thing as the total offense level.
MR. O’BRIEN: Right. And from the base offense level you have adjustments up and adjustments down.
THE COURT: Exactly....
J.A. at 112.
In reaching this conclusion, however, the district court overlooked the term “relevant conduct” in the plea agreement, and failed to consider the fact that “relevant conduct,” like “base offense level,” is a term with a specialized meaning under the guidelines. Under Sentencing Guidelines § 1B1.3 the term “relevant conduct” means “Factors that Determine Guideline Range.” The section includes as relevant conduct those factors that contribute to adjusting the offense level upward. Thus, “relevant conduct” incorporates “the base offense level ... specific offense characteristics ... and adjustments in Chapter Three....” U.S.S.G. § lB1.3(a)(i)-(ii), (iv). As already explained, the base offense level is the starting point in the sentencing analysis. A defendant’s leadership role is an adjustment to the base offense level, allowable pursuant to U.S.S.G. § 3Bl.l(a). The base offense level therefore can be increased by the specific offense characteristics in Chapter Two and/or adjustments in Chapter Three. The sentencing guidelines define all of these factors as “relevant conduct.” Therefore, we conclude that it was eminently reasonable for Fitch to believe that when the government agreed to recommend that no other “relevant conduct” be used to increase her base offense level, the government foreclosed any further opportunity to increase her sentence by means of the leadership role enhancement under § 3Bl.l(a).
Ambiguities in a plea agreement must be construed against the government.
United States v. Randolph,
Having done so, we must necessarily conclude that the government breached the plea agreement. The Supreme Court has held that “when a plea rests in any significant degree on a promise or agreement of the prosecutor, so that it can be said to be part of the inducement or consideration, such promises must be fulfilled.”
Santobello v. New York,
Fitch also argues that the district court increased her base offense level in light of her leadership role in violation of
Apprendi v. New Jersey,
III. CONCLUSION
We must therefore vacate the defendant’s sentence and remand for resentenc-ing before a different district court judge.

Notes
. Section 3B1.1(a) provides:
"Based on the defendant's role in the offense, increase the offense level as follows:
(a) If the defendant was on organizer or leader of a criminal activity that involved five or more participants or was otherwise extensive, increase by 4 levels.”
U.S.S.G. § 3B 1.1(a).
