(1) Assumes conversion of the full amount of notes held by such holder at
the current conversion price of $67.80 per share; such conversion price
is subject to adjustment as described under "Description of Notes -
Conversion of Notes." The initial conversion price of $135.60 per share
of common stock has been adjusted to reflect the two-for-one forward
stock split effected by TriQuint as a stock dividend on July 11, 2000 to
stockholders of record on June 19, 2000. Accordingly, the number of
shares of common stock issuable upon conversion of the Notes may
increase or decrease from time to time. Under the terms of the
Indenture, fractional shares will not be issued upon conversion of the
notes; cash will be paid in lieu of fractional shares, if any.
(2) Computed in accordance with Rule 13d-3(d)(i) promulgated under the
Exchange Act and based upon 78,129,386 shares of common stock
outstanding as of July 1, 2000, treating as outstanding the number of
shares of common stock shown as being issuable upon the assumed
conversion by the named holder of the full amount of such holder's notes
but not assuming the conversion of the notes of any other holder. The
number of shares outstanding on July 1, 2000 as presented reflects the
two-for-one forward stock split effected by TriQuint on July 11, 2000
through a stock dividend to stockholders of record on June 19, 2000.
(3) The amounts presented herein are in addition to those reported by the
Selling Securityholder in the prospectus supplements dated June 16, 2000
and July 7, 2000.
