Director Shareholding

GlaxoSmithKline PLC
08 September 2004

                              Directors' Interests

I give below details of changes in directors' interests in the Ordinary Shares
of GlaxoSmithKline plc.


7 September 2004     Abacus (GSK) Trustees Limited, as trustee of the
                     GlaxoSmithKline Employee Trust, ("GSK Trust"), transferred
                     580 Ordinary Shares in the Company to participants in the
                     SmithKline Beecham Employee Share Option Plan 1991.


The Company was advised of this transaction on 8 September 2004.

The GSK Trust is a discretionary trust of which all employees or former
employees of GlaxoSmithKline plc and its subsidiaries are potential
beneficiaries. Three of the Company's directors, Dr J-P Garnier, Dr T Yamada and
Mr J D Coombe are therefore interested in the shares held in the GSK Trust from
time to time in the same way as other employees or former employees of
GlaxoSmithKline plc and its subsidiaries.
