39 Compelling Strategic Rationale ? Adds proprietary high voltage (50V to 1000V) analog and mixed signal products to our portfolio ? Adds high voltage process technologies and know how that will enable new solutions for our current businesses ? Expands our footprint in the long life cycle Medical and Industrial market segments ? Expands our position in fast growing LED and general lighting applications ? Microchip’s strong manufacturing and sales channel strengths can extend the reach of Supertex’s solutions into new applications and markets ? Adds strong patent portfolio to Microchip IP portfolio

40 Next Steps ? Microchip and Supertex executives will work towards completing the acquisition expeditiously. ? We expect to close transaction in CQ2, 2014. ? We will form an integration team consisting of employees from both companies who will outline the integration strategy in areas of IT, HR, finance, legal, operations, product lines and sales.

41 Some Answers in the HR area ? Your vested stock options will be cashed out at $33 stock price. ? Your unvested stock options will be assumed by Microchip adjusted for the exchange ratio. ? # of options = Current number of options x $33/MCHP stock price ? Option price= Current option price x MCHP stock price/$33 ? The vesting schedule will remain the same

42 Answers– contd. ? Supertex’s ESPP will be terminated and employees can join Microchip’s ESPP ? Microchip’s U.S. ESPP plan has a two year look back period and is therefore more favorable than Supertex’s ESPP plan. ? Our international ESPP plan is similar to Supertex’s ESPP plan. ? Supertex’s 401K plan will be frozen and employees can enroll into Microchip’s 401K plan. ? Supertex’s 401K plan will undergo IRS audit. Once proven compliant, all the funds will roll over into Microchip’s 401K plan.
