MERCURE, J.
Defendant was indicted for two counts of burglary in the first degree as the result of a September 7, 1997 incident in which defendant, his two codefendants and several of their fraternity brothers broke into a student residence in the City of Binghamton, Broome County. During the course of the incident, the codefendants assaulted occupants of the residence with a baseball bat and a beer bottle. Ultimately, defendant disposed of the indictment with a plea of guilty to a single count of burglary in the second degree.
Prior to sentencing, defendant submitted to questioning by the investigating police officers and the prosecutor. Then, alleging the existence of an unrecorded promise by the People that if he cooperated with the prosecution, "such cooperation would be fairly evaluated by the prosecution and would be afforded appropriate consideration in terms of permitting the withdrawal of [defendant's guilty] plea and entry of a plea to a reduced count, at a reduced sentence", defendant sought an adjournment of sentencing pending a hearing to determine the existence, nature and scope of any promises of consideration made by the prosecution as an inducement of defendant's plea and cooperation and, further, that County Court enforce any such promise in sentencing defendant. County Court denied the application and sentenced defendant to an indeterminate prison term of 2 1/4 to 4 1/2 years.
Defendant thereafter moved pursuant to CPL 440.10 to, among other things, vacate the judgment of conviction or, in the alternative, for an order granting a hearing to determine whether such judgment should be vacated as a result of duress, misrepresentation or fraud on the part of the prosecution, or improper and prejudicial conduct outside the record that would constitute reversible error if it was part of the record on appeal, or as having been obtained in violation of defendant's constitutional rights. County Court denied the motion without a hearing. Defendant now appeals the judgment of conviction and, by permission, the order denying his CPL 440.10 motion.
We affirm. Initially, we are unpersuaded by the contention that the judgment of conviction was procured by any unfulfilled promise on the part of the prosecutor. We first note that essentially the same contentions were advanced by a codefendant on a prior appeal and rejected by this court upon the ground that, if the agreement alleged by the codefendant actually existed, it was incumbent upon him to enter such information on the record prior to or at the time of his plea (People v. Anonymous, 262 A.D.2d 717, 718, 692 N.Y.S.2d 485, 487, lv denied 93 N.Y.2d 1013). No compelling argument has been made for reaching a contrary result here. Indeed, it has long been the rule that the court is entitled to rely upon the record of the plea proceedings to ascertain whether any promises were made to induce the guilty plea (see, People v. Frederick, 45 N.Y.2d 520, 528; People v. Selikoff, 35 N.Y.2d 227, 244,cert denied 419 U.S. 1122; People v. Miner, 126 A.D.2d 798, 799).
We also note that, by defendant's own description, the off-the-record promise he seeks to enforce merely provided that if he cooperated with the prosecution, his cooperation would be "fairly evaluated" and compensated with "appropriate consideration" in terms of permitting withdrawal of his original guilty plea and substitution of a plea to a reduced count with a lesser sentence. In our view, such an amorphous claim of entitlement to "appropriate consideration" in exchange for an unidentified type and measure of "cooperation" to be given the prosecution is too vague and ambiguous to support a claim for specific performance (see, People v. Reyes, 167 A.D.2d 920, 920-921,lv denied 77 N.Y.2d 842; see also, Varney v. Ditmars, 217 N.Y. 223;McGee Gelman v. Park View Equities, 187 A.D.2d 1012, 1013; 96 N Y Jur.2d, Specific Performance, § 18, at 297-300). Further, in view of the fact that defendant received the most lenient permissible sentence on his conviction of a class C violent felony offense (see, Penal Law former § 70.02 [1] [b]; [2] [a]; [3] [b]; [4]), we lack discretion to modify the sentence.
Changes to Penal Law § 70.02 (2) (a), (3) and (4) made by Laws of 1998 (ch 1, §§ 5, 7, 8) applied only to offenses committed on or after September 1, 1998 (see, L 1998, ch 1, § 44). Offenses (such as the present one) committed prior to that date were governed by the provisions of law in effect at the time of their commission (see, L 1998, ch 1, § 44).
As a final matter, we reject the contention that defendant's plea allocution was insufficient. Although not necessary in view of the fact that defendant entered a bargained-for plea to a lesser crime than those charged in the indictment (see, People v. Moore, 71 N.Y.2d 1002, 1006; People v. Clairborne, 29 N.Y.2d 950, 951), the allocution established all of the elements of the crime to which defendant entered his plea (see, Penal Law § 140.25).
