Dear Hank:

I am  pleased  to  offer  you  employment  with  Zarlink  Semiconductor  LE Inc.

All amounts are in United States dollars.

Zarlink is an "at will" employer and your  employment with Zarlink is an at-will
relationship,  subject to any payments or other  consideration due to you in the
event of your termination  without Cause.  This means that either Zarlink or you
may terminate the employment  relationship  at any time for any reason,  with or
without cause or advance notice.

offices.  Your  start  date will be  immediately  following  the  closing of the
Legerity acquisition.  Your employment will automatically terminate one (1) year
from your start date unless the term is extended by mutual agreement.

In this position, you will devote your best efforts, and your full working time,
skill and attention,  to carrying out your duties and to promoting the interests
of the  Company.  You will be  expected  to  perform  all  services  and  duties

Company,  you will be entitled to receive a retention  bonus equal to  $350,000.
The retention bonus, less applicable statutory deductions and withholdings, will
be payable after the completion of one (1) year of employment; provided however,
if your employment is earlier  terminated by the Company without Cause, you will
be entitled to receive 100% of the retention bonus or any unpaid portion thereof
upon termination.  The retention bonus payment will be made within 30 days after
the

anniversary date of employment,  or in the case of termination without Cause, on
the Termination Date.

3.    Health, Dental and Related Benefits

Zarlink will maintain  Legerity's current  comprehensive group employee benefits

accordance  with the specific  terms and  conditions of the plan. We reserve the
right to terminate or amend any of these plans from time to time.

4.    Pension

You will be entitled to  participate  in the Zarlink  U.S.  employee  401K Plan.
