11. LSE Share Option Schemes
The Ordinary Offer extends to any LSE Ordinary Shares which are unconditionally allotted or issued as a result of the exercise of options granted under the LSE Share Option Schemes whilst the Final Offers remain open for acceptance or before such earlier date as NAL may, subject to the City Code, decide.
If the Ordinary Offer becomes or is declared unconditional in all respects, appropriate proposals will be made to holders of options under the LSE Share Option Schemes.
