Before SCHWAB, C.J., and LANGTRY and THORNTON, JJ.
THORNTON, Judge.
Defendants were jointly tried on separate indictments, each charging two counts of first degree robbery, ORS 164.415, and one count of second degree robbery, ORS 164.405.[1] The court granted defendants' motion of acquittal as to Count II (first degree robbery) of each indictment and submitted Count I (first degree) and Count III (second degree) of each to the jury.
After 15 hours of deliberation, the jury reported that it was deadlocked, and that the vote stood 9 jurors for acquittal and 3 for conviction. Supplemental instructions were given concerning the state's burden of proof, the meaning of reasonable doubt and the jury's duty to reach a verdict.[2] Immediately thereafter the trial court specifically asked each defense attorney for his exceptions and comments. Both counsel stated that they had no exceptions to the court's supplemental instructions, and that they preferred to await the immediate results. The prosecuting attorney likewise expressed agreement with the court's actions.
After slightly more than an hour of additional deliberation, the jury informed the court that it had reached a verdict. By a vote of 10 to 2 the jury found each defendant guilty of two counts of third degree robbery.
On appeal, defendants argue that giving the supplemental instructions violated their constitutional right to a fair trial.
We will not consider this assignment because defendants failed to make timely objection below. The record shows that it was only after the jury returned guilty verdicts that defendants objected to the supplemental instructions. Questions not timely raised and preserved in the trial court will not be considered on appeal in the absence of exceptional circumstances. State v. Avent, 209 Or. 181, 302 P.2d 549 (1956). See also, State v. Ledford, 14 Or. App. 625, 514 P.2d 564 (1973), Sup. Ct. review denied (1974); State v. Barton, 8 Or. App. 186, 492 P.2d 828, Sup. Ct. review denied, cert. denied 409 U.S. 852, 93 S.Ct. 64, 34 L.Ed.2d 95 (1972); State v. Jorgensen, 8 Or. App. 1, 492 P.2d 312 (1971), Sup. Ct. review denied (1972); State v. Phillips, 5 Or. App. 60, 61, 481 P.2d 381, Sup. Ct. review denied (1971), cert. denied 406 U.S. 972, 92 S.Ct. 2419, 32 L.Ed.2d 673 (1972). This rule applies as well in cases in which the asserted error was in the giving of instructions and where no proper exception was taken. State v. Marsh, 260 Or. 416, 439, 490 P.2d 491 (1971), cert. denied 406 U.S. 974, 92 S.Ct. 2420, 32 L.Ed.2d 674 (1972).
Defendants argue that we should take notice of this asserted error under the "plain error" exception in Rule 6.18[3] of *357 this court. However, we are satisfied that this case does not come within the "plain error" exception contained in Rule 6.18.[4] State v. Marsh, supra.
Finally defendant Mitchell contends that the trial court erred in sentencing him on Counts I and II of the indictment because he was acquitted on Count II. Defendant Mitchell was convicted of third degree robbery on Counts I and III; however, he was sentenced on Counts I and II. We therefore vacate defendant Mitchell's sentence and remand him to the trial court for resentencing.
Convictions affirmed. Remanded for resentencing as to defendant Mitchell.
NOTES
[1]  The indictments are identical except the names of the two defendants.
[2]  The instruction given on the jury's duty to reach a verdict was identical to the American Bar Association's proposed supplemental instruction to deadlocked juries approved in State v. Marsh, 260 Or. 416, 443, n. 58, 490 P.2d 491 (1971), cert. denied 406 U.S. 974, 92 S.Ct. 2420, 32 L.Ed.2d 674 (1972).
[3]  Rule 6.18:

"In appeals in actions at law, no alleged error of the trial court will be considered on appeal unless regularly assigned as error in the appellant's (or cross-appellant's) opening brief, except that the appellate court may take notice of errors of law apparent on the face of the record.
"* * *."
[4]  In view of the fact that the jury stood 9 to 3 for acquittal at that juncture, defendants' failure to object to the supplemental instructions at that time may well have been for reasons of trial tactics  believing that the jury was close to returning not guilty verdicts.
