ST ANDREW GOLDFIELDS LTD.
   
RE:
Sale of assets by St Andrew Goldfields Ltd. ("St Andrew") to Apollo Gold
Corporation ("Apollo") pursuant to an asset purchase agreement dated the 6th day
of June, 2008, as amended by amending agreement dated the 30th day of June, 2008
(collectively, the “Asset Purchase Agreement”).

____________________________________________________________________________
 
For good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged by the parties, Apollo hereby acknowledges and agrees as
follows:
1. The provisions contained in section 7.1 of the Asset Purchase Agreement shall
have no application to the proposed purchase (the "Proposed Purchase") by St
Andrew of up to 2,400,000 units of Apollo, with each unit consisting of one
share of common stock (the "Common Shares") of Apollo and one half of one
warrant (the "Warrants") to purchase common stock of Apollo (the "Securities")
to be sold pursuant to a short form prospectus of Apollo dated July 9, 2008 (the
"Apollo Financing").
2. Upon the completion of the Proposed Purchase, 2,400,000 common shares of
Apollo currently held by St Andrew shall be immediately free from the provisions
contained in section 7.1 of the Asset Purchase Agreement which, for greater
certainty, shall be in addition to the common shares of Apollo which St Andrew
may sell pursuant to section 7.1 of the Asset Purchase Agreement.
3. Apollo undertakes to file as soon as practicable after the date hereof a
registration statement (or an amendment to the existing registration statement),
as applicable, with the Securities and Exchange Commission to register for
resale the Common Shares and Warrants included in the Securities within 60 days
from the closing of the Proposed Purchase. Apollo covenants and agrees to make
such filings and take all steps necessary to maintain the effectiveness of such
registration statement  until St Andrew can sell all of the Securities in a
single transaction in compliance with Rule 144 under the United States
Securities Act of 1933, as amended.

--------------------------------------------------------------------------------

4. Within two (2) Business Days (as defined in the Asset Purchase Agreement) of
the completion of the Apollo Financing, Apollo shall pay to St Andrew the
balance of the purchase price owing under the Asset Purchase Agreement, namely
$14,500,000, together with all accrued and unpaid interest thereon, as
determined in accordance with the Asset Purchase Agreement.
5. This Consent and Undertaking may be executed by facsimile or other electronic
means, which shall be as effective as an originally executed copy.
