¶1OPINION ON APPELLANT’S PETITION FOR DISCRETIONARY REVIEW
¶2Appeal is taken from a conviction for the offense of aggravated robbery. After finding appellant guilty, the jury assessed punishment at 99 years in the Texas Department of Corrections and a $10,000.00 fine.
¶3On direct appeal, appellant argued the trial court erred in instructing the jury on the law concerning good time and parole, inasmuch as the charge is predicated upon an unconstitutional statute. The court of appeals rejected appellant’s challenge to *22Article 37.07, § 4, Y.A.C.C.P. Willis v. State, 736 S.W.2d 196 (Tex.App.—Beaumont 1987).
¶4In his petition for discretionary review, appellant urges the court of appeals erred in holding Article 37.07, § 4, supra, is constitutional. We find appellant is correct.
¶5In Rose v. State, 752 S.W.2d 529 (Tex.Cr.App.1988), this Court determined that Article 37.07, § 4, is unconstitutional. Under Rose, supra, it is still necessary for the court of appeals to conduct a harmless error analysis under the guidelines of Tex. R.App.P. 81(b)(2).
¶6The judgment of the court of appeals is vacated and this cause is remanded to that court for further proceedings consistent with this opinion.
