Pursuant to Rule 416 under the Securities Act of 1933, as amended ("Securities
Act"), this Registration Statement also covers an indeterminate number of
additional shares of common stock that become issuable under Altera
Corporation's (the "Registrant") the 2005 Equity Incentive Plan and 1987
Employee Stock Purchase Plan by reason of any stock dividend, stock split,
recapitalization or any other similar transaction effected without the receipt
of consideration, which results in an increase in the number of the Registrant's
outstanding shares of common stock.
(2) The
proposed maximum offering price per share and proposed maximum aggregate
offering price are estimated solely for purposes of calculating the registration
fee.
(3)
Computed in accordance with Rule 457(h) and Rule 457(c) of the Securities
Act.  Such computation is based on the average of the high and low
price of the Registrant's common stock as reported on The NASDAQ Global Market
on August 11, 2008.
