After fourteen years of working, Torres took a one-year break to travel and focus on his charity work from July 2008 to July 2009. Before joining Capella, Torres was the CFO and Vice President of Finance for Power Integrations (Nasdaq: POWI), a leader in high-voltage analog integrated circuits for power conversion from July 2006 to July 2008, where he led a financial turnaround that he successfully achieved. Prior to that, Torres was CFO and Vice President of Finance for PLX Technology (Nasdaq: PLXT), a global leader in PCI Express (PCIe) silicon and software connectivity solutions enabling emerging data center architectures from November 2000 to July 2006 and through his leadership, returned the company to profitability and significantly increased their cash position.

Pursuant to the offer letter, Mr. Torres’s initial annual base salary will be $300,000. Mr. Torres will be included in the OCZ Bonus Program with the target bonus of $175,000 and prorated as of March 25, 2013. Additionally, Mr. Torres will receive a signing bonus of $25,000 after 30 days of satisfactory employment. Mr. Torres was also granted an option to purchase 200,000 shares of the Company’s Common Stock at an exercise price equal to the fair market value of that stock on the date of the grant (the “Option”). The Options will vest 25% at the end of his first year of employment and 1/36th of the remaining balance each month thereafter for an additional 36 months, for a total vesting period of 48 months. Mr. Torres was also granted 50,000 Restricted Stock Units (“RSU”). The RSUs will vest 25% per year for four years. The Company will provide Mr. Torres $500,000 worth of life insurance and he is entitled to participate in the Company’s other employee benefit programs.
