Dear GWR Shareholder

If you have already accepted Fairstar's offer you don't need to take any further action; the reason you are receiving this letter is that your acceptance is still being processed.

In case you have mislaid the original Acceptance Form enclosed with Fairstar's offer document, a replacement form is enclosed for your use.

Yours-faithfully
