Why are we here today?

ISSI has determined that you hold certain stock

options that may be negatively affected by a recent

tax law change.

ISSI has developed a solution to address the

problem, but which requires your participation and

permission to implement.

If you do not participate, you may have adverse tax

consequences.

Tax Law Change:

409A

Tax Law Change:

409A

409A is a set of operating and tax rules for items

considered to be deferred compensation.

Certain stock options are now considered to be

deferred compensation.

What are the consequences of 409A?

–

Potential income taxation prior to exercise

–

40% additional tax (20% federal & 20% CA)

–

Interest penalty

2007 ISSI, INC. -

Page 5

Which options are affected?

Options granted at a price below the stock’s fair market

value (FMV) on the actual grant date (“Discount

Options”).

Only options that vest AFTER 12/31/04.

•

Thus, options granted prior to 409A’s enactment could be affected

by this new law if they vested 1/1/05 and later.

2007 ISSI, INC. -

Page 6

Example:

Option granted on Jan 1, 2003 –

10,000 shares

Option price = $2.50,

but fair market value at grant date =

$5.50

Vesting:

2,500 options vest on Jan 1, 2004

–

2,500 options vest on a monthly basis during 2004

–

2,500 options vest on a monthly basis during 2005

–

2,500 options vest on a monthly basis during 2006

–

CONCLUSION:

–

The 5,000 options that vested prior to 1/1/05 are NOT subject to

409A.

–

The 5,000 options that vest after 12/31/04 are subject to 409A

because they were granted at a discount.

2007 ISSI, INC. -

Page 7

Example: (continued)

Assume that the fair market value of the option shares on the

applicable tax date is $7.50 and no options were exercised.

409A Estimated Tax Impact:

–

Eligibility

Must be an employee at the close of the Tender Offer

and subject to US income taxation.

Offer covers unexercised options that were granted

at a discount and vest after 12/31/04.

You can select which of your affected grants to

tender (i.e., participate with), but once selected, the

entire unexercised posrtion

subject to 409A must be

tendered.

Page 15

Program 2: Options Out of the Money

If your new option exercise price would be higher than

the fair market value of ISSI stock on the day the tender

offer is completed, your option price will equal the ISSI

closing stock price but will not be higher

This will result in a lower stock option price for you

Since this will increase the value of the stock option, the

quantity of options will be converted to an economically

equivalent number of shares, which will be lower
