This Amendment of Exclusivity Agreement (this “Agreement”), is entered into, as
of May 4, 2007, by and between Black Sands Petroleum, Inc., a Nevada corporation

Whereas, Blacksands and Access extended the exclusivity period until May 8, 2007
by an Amendment to the Exclusivity Agreement, dated March 9, 2007;

Whereas, Blacksands and Access desire now to extend the Exclusivity Period

valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties agree as follows:

all other provisions of the Exclusivity Agreement remain in full force and
effect.

SECTION 5. Counterpart Signatures. This Agreement may be executed in two or more

same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
