Director/PDMR Shareholding

RNS Number : 7830K

GlaxoSmithKline PLC

24 December 2008

This announcement replaces the original announcements released on 6 May 2008 at 16.30 (RNS No: 8168T); 4 August 2008 at 18.11 (RNS No: 6189A); and 7 November 2008 at 18.02 (RNS No: 7658H).

The Administrators of the GlaxoSmithKline Performance Share Plan (the "Plan") notified the Company on 8 December 2008 of a correction to the market price of Ordinary shares used to calculate the number of shares reinvested under the dividend reinvestment element of the Plan for participants who both received Ordinary shares and who were detailed in the affected original announcements, in respect of dividends paid to shareholders on 10 July 2008. The market price of Ordinary shares should have read £11.21 (rather than £11.20), and the participants' increased interests in Ordinary shares have been corrected.

Given the cumulative nature of dividend reinvestment, the correction in respect of the payment made on 10 July 2008 also had a minor impact on the calculation of the dividends reinvested for the affected Plan participants in respect of the payments made on 9 October 2008 and 8 January 2009.

Details in respect of JP Garnier, C Viehbacher and SM Werner are excluded from these replacements as JP Garnier and C Viehbacher are no longer directors of the Company, and SM Werner is no longer deemed a Person Discharging Managerial Responsibility.

Save as disclosed above, all other details remain unchanged.
