Before DEITS, P.J., and RIGGS and HASELTON, JJ.
*377 RIGGS, Judge.
Pursuant to plea negotiations, defendant pleaded guilty to aggravated murder. ORS 163.095. She now appeals and argues that her sentence exceeds the maximum allowable by law. We affirm.
Defendant was originally charged by information with seven counts, alleging activities that occurred in 1990. She entered into plea negotiations with the district attorney and those negotiations led to an agreement. The plea agreement, which the trial court approved on the record, provided in part:
"I am stipulating to a life sentence without the possibility of release or parole, as described in ORS 163.105(1)(b), reserving my right to appeal the constitutional issue whether life without parole is a legal sentence under Article I, Section 40, of the Constitution of the State of Oregon."
Defendant argues on appeal that a "life sentence without the possibility of parole" for aggravated murder violates Article I, section 40, of the Oregon Constitution.[1] The state argues that we cannot review defendant's claim of error.
"The right to appeal is statutory and subject to any limitations imposed by the statute conferring that right." State v. Adams, 315 Or. 359, 364, 847 P.2d 397 (1993); Logsdon v. State and Dell, 234 Or. 66, 70, 380 P.2d 111 (1963). Here, defendant asserts that we may review her assignment of error under ORS 138.050, which provides:
"(1) A defendant who has pleaded guilty or no contest may only take an appeal from a judgment or order described in ORS 138.053 where the disposition:
"(a) Exceeds the maximum allowable by law; or
"(b) Is unconstitutionally cruel and unusual."
However, ORS 138.222, as amended by the 1993 legislature, provides:
"(1) Notwithstanding the provisions of ORS 138.040 and ORS 138.050, a sentence imposed for a judgment of conviction entered for a felony committed on or after November 1, 1989, may be reviewed only as provided in this section.
"(2) On appeal from a judgment of conviction entered for a felony committed on or after November 1, 1989, the appellate court shall not review:

"* * * * *
"(d) Any sentence resulting from a stipulated sentencing agreement between the state and the defendant which the sentencing court approves on the record." (Emphasis supplied.)
The Supreme Court, in State v. Kephart, 320 Or. 433, 887 P.2d 774 (1994), construed the amended version of ORS 138.222(2)(d) and held that it "allow[s] review of sentences unless they [are] `stipulated sentences' as illustrated in ORS 135.407." 320 Or. at 447, 887 P.2d 774. Therefore, we must examine the plea agreement here to determine if it results in a "stipulated sentence" such that review is precluded by ORS 138.222(2)(d). To do that, we must determine whether a plea agreement that is not pursuant to ORS 135.407 can qualify as a "stipulated sentencing agreement."
In Kephart, the Supreme Court examined the text and context, as well as the legislative history, of the amended version of ORS 135.222 to determine what the legislature meant by a "stipulated sentencing agreement."
The court asserted that it could "discern from the text [of ORS 138.222(2)(d)] that [a stipulated sentencing] agreement must at least define sentencing parameters, if not the actual sentence to be imposed." 302 Or. at 441, 887 P.2d 774. (Emphasis supplied.) The court then considered the context of ORS 138.222(2)(d) and examined ORS 135.407. It held that the possible stipulations envisioned by ORS 135.407 "should be included within the new class of `stipulated sentencing agreements.'" 320 Or. at 442, 887 P.2d at 774. However, the court also *378 noted that the text and context did not make the legislative intent clear and that the ORS 135.407 stipulations "may merely be illustrative of the class, rather than the entire class." 320 Or. at 442, 887 P.2d 774.
Turning to the legislative history, the Supreme Court discerned that the 1993 amendment to ORS 138.222(2)(d), which introduced the "stipulated sentencing agreement" language, was intended to preserve the result in State v. Adams, supra, while reversing the result in State v. Kilborn, 120 Or.App. 462, 852 P.2d 935 (1993), and a line of cases including State v. Tanner, 121 Or.App. 104, 854 P.2d 941, rev. den. 318 Or. 98, 863 P.2d 1268 (1993), and State v. Johnston, 120 Or. App. 165, 851 P.2d 1156, rev. den. 317 Or. 272, 858 P.2d 1314 (1993). In Adams, the defendant agreed to a particular grid block for sentencing, as allowed by ORS 135.407(1). However, in Kilborn, the defendant and the district attorney did not have an "agreed upon sentence"; instead, the parties agreed that the prosecutor would stand silent at sentencing. The Supreme Court understood that the proponents
"intended the amendment to permit appellate review of `illegal' sentences, unless the defendant agreed to that sentence ahead, of time as part of a `stipulated sentencing agreement.'" 320 Or. at 445, 887 P.2d 774. (Emphasis supplied.)
The Supreme Court found nothing in the legislative history that indicated that the legislature intended to "expand on the kinds of stipulated sentences specified in ORS 135.407," and held that ORS 138.222(2)(d) allows review of sentences "unless they [are] stipulated sentences as illustrated in ORS 135.407." State v. Kephart, supra, 320 Or. at 447, 887 P.2d 774. (Emphasis supplied.)
If a plea agreement is pursuant to ORS 135.407, it results in a "stipulated sentencing agreement" and is unreviewable. However, in this case, we must determine whether any other agreements are of a kind "illustrated" by ORS 135.407. If the agreement only "tangentially relates" to sentencing, State v. Tanner, supra, or if the agreement only requires the prosecutor to remain silent at sentencing, State v. Kilborn, supra, or if the agreement is not followed by the sentencing judge, State v. Johnston, supra, then the sentence is not the result of a stipulated sentencing agreement and review is not prohibited. In this case, the agreement related to sentencing. It set the specific sentence to be imposed and the court imposed that sentence. It appears that this is the very type of agreement contemplated by the legislature, which intended to prevent review of sentences where "the defendant agreed to that sentence ahead of time."
The only reason this agreement is not pursuant to ORS 135.407 is because the sentences for aggravated murder are set by statute. That led the State Sentencing Guidelines Board (Board) not to include this crime within its sentencing grid:
"The offense of Aggravated Murder is not ranked in the Crime Seriousness Scale because the sentence is set by statute as death or mandatory life imprisonment." OAR 253-04-003.
If the Board had included aggravated murder within its sentencing grid, this agreement would fit squarely within either ORS 135.407(4) or (5) and would be unreviewable. We find it inconceivable that the legislature intended to allow review of this sentence simply because aggravated murder was not included within the sentencing grid. Accordingly, we hold that this sentence is a "`stipulated sentence' as illustrated in ORS 135.407" and, therefore, unreviewable.
Defendant's purported reservation of the right to appeal does not alter the fact that this was an "agreed upon" sentence, and cannot confer the authority to review on us. State v. Boretz, 75 Or.App. 146, 148, 706 P.2d 559, rev. den. 300 Or. 477, 713 P.2d 1058 (1985). Because we may not review her assignment of error, we affirm.
Affirmed.
NOTES
[1]  Article I, section 40, provides:

"Notwithstanding sections 15 and 16 of this Article [regarding reformation as the basis of criminal law and cruel and unusual punishments], the penalty for aggravated murder as defined by law shall be death upon unanimous affirmative jury findings as provided by law and otherwise shall be life imprisonment with minimum sentence as provided by law."
