GlaxoSmithKline plc - Share Buy-Back Programme

GlaxoSmithKline plc (the "Company") announces that it has today put in place an irrevocable, non-discretionary programme for the purchase of its Ordinary shares during the close period which precedes the 2008 second quarter results announcement, expected to be made on 23 July 2008.  The shares purchased on behalf of the Company are for cancellation.

The aim of the programme is to reduce the issued share capital of the Company to help enhance returns for shareholders.

The share buy-back programme will be managed by an independent third party which makes its trading decisions in relation to the Company's securities independently of, and uninfluenced by, the Company.

Any purchases pursuant to these arrangements will be effected during the period between 1 July 2008 and 23 July 2008
within certain pre-set parameters and in accordance with both the Listing Rules and the limitations of the repurchase authority granted to the Directors at the last Annual General Meeting of shareholders. The Company confirms that it currently has no inside information.

Company Secretary
