g)	If neither d) nor e) above occurs and Wescorp does not register the First Tranche by filing and clearing a registration statement with the United States Securities and Exchange Commission within 270 days of April 30, 2004, then Abuelo will have the option and right to terminate this Agreement pursuant to section 3.4 hereof."
