5 THE ISSUE: DISCOUNTED OPTIONS

6 How Stock Options are taxed • Employees not taxed when Options granted or when they vest • Employees taxed when they exercise Options • Taxable Benefit = Fair market value of shares on date of exercise, minus Exercise Price

7 Favorable Tax Treatment • Deduction of 50% of Taxable Benefit in computing federal and provincial (except Quebec) taxable income available in certain circumstances • Deduction for Quebec income tax purposes is 25% not 50% • 50% federal and 25% Quebec deduction ** are not available for Options issued at a Discounted Exercise Price ** For simplicity, the rest of this presentation will refer to the “50% deduction”

8 Option taxation - example • Income tax at exercise Assume option grant price $20 Employee exercises when stock price $25 Income tax at exercise on the spread ($25 - $20) = $5 200 options exercised • If eligible, taxable income = Taxable benefit at exercise $5 x 200 = $1,000 Deduction of 50% of $1,000 ( 500) Net taxable income $ 500 • Reported on Form T4 Spread at exercise - $1,000 Amount eligible for 50% deduction - $1,000

9 • Options granted at a discount (dates shown on the next slide) • Which have not been exercised as of September 11, 2008 Which options are affected?

10 Affected Grants Original Date of Grant Original Option Exercise Price(1) FMV on Accounting Measurement Date (Corrected Exercise Price)(1) Price Differential March 28, 2001 $21.56250 $23.46875 $1.90625 May 23, 2001 $30.00000 $30.685000 $0.685000 November 19, 2002 $23.99000 $25.86000 $1.87000 December 9, 2002 $21.72500 $22.19000 $0.46500 May 19, 2003 $25.00000 $29.32500 $4.32500 May 17, 2004 $25.19000 $29.37000 $4.18000 July 16, 2004 $24.92000 $25.69000 $0.77000 December 10, 2004 (1) Reflects 2:1 stock split on September 23, 2003 $17.58000 $18.23000 $0.65000

11 How did I get discounted options? • Old option grant process used through end of 2005 • Company granted options monthly during a “grant week” • Exercise price used was lowest closing price during the grant week • Old process created discount of the difference between • SNPS fair market value on the accounting measurement date (generally Friday, when the lowest price of the grant week was known), and • the lowest closing price of the grant week • Old process was NOT used for executive officers

12 • Assume an option for 500 shares granted on December 13, 2001 vesting (100 shares per year) • Exercise price = $19, but fair market value on appropriate accounting measurement date (Friday, Dec 14, 2001) = $20 • Exercises: • 300 shares previously exercised • 200 shares remaining • 300 shares exercised: • Were granted at less than fair market value on the date of grant, • Taxable benefit on exercise should not have been eligible for the 50% deduction • 200 shares remaining: • Were granted at less than fair market value on the date of grant, • Taxable benefit on exercise will not be eligible for the 50% deduction Tax consequences of discounted options – Example

13 SNPS Solution: Tender Offer • Tender Offer To remedy unexercised options so that they will be eligible for the 50% deduction

14 TENDER OFFER

15 SNPS Solution: Tender Offer • Amend unexercised option to increase option exercise price to remove the discount • New option price will equal the fair market value on the appropriate accounting measurement date (generally the Friday of the grant week) • All other terms will remain the same (including the number of shares, vesting schedule and expiration date).

16 • Unexercised option for 500 shares granted on December 13, 2001 vesting over five years • Option price = $19, but fair market value on appropriate accounting measurement date (Friday, December 14, 2001) = $20 • Exercised: • 300 shares already exercised prior to Tender Offer – no change in exercise price • Option Amendment • 200 options unexercised will have an exercise price of $20 Hypothetical Example (amended option)

17 Example (amended option) • Assume that SNPS stock price on exercise is $25 • Taxable benefit = $1,000 (200 shares x $5 ($25 FMV - $20 exercise price)) Taxable benefit $ 1,000 Tax calculation Taxable benefit $ 1,000 Less: 50% deduction $ (500) Taxable income $ 500 Estimated federal and provincial income tax (40% combined rate) 40% $ 200 After tax gain if shares sold at $25.00 $ 800

18 Example (if option not amended) • Assume that SNPS stock price on exercise is $25 • Taxable benefit = $1,200 (200 shares x $6 ($25 FMV - $19 exercise price)) Taxable benefit $ 1,200 Tax calculation Taxable benefit $ 1,200 Less: 50% deduction $ - Taxable income $ 1,200 Estimated federal and provincial income tax (40% combined rate) 40% $ 480 After tax gain if shares sold at $25.00 $ 720
