Dear Michael:

This offer
letter replaces in its entirety the offer letter that I sent to you on April 22, 2002.

I am very
pleased to offer you employment with ADC for the position of ADC Vice President and
President of ADC's Wireline Business  Unit.  You will report directly to ADC's CEO Rick
Roscitt. The terms of our offer are as follows:

SalaryYour
starting salary will be at an annualized rate of $350,000, payable bi-weekly.

Sign On Bonus
ADC will provide you a one-time sign on bonus of $75,000, less all-applicable
withholdings, to be paid to you within 30 days of your employment.

Annual
IncentiveYou are eligible to participate in the FY02 Management Incentive Plan. The
plan provides a target opportunity of 55% of salary paid during the fiscal year.

Stock Option
GrantEffective the last trading day of the month in which your employment with ADC
begins, you will be granted non-qualified options in 325,000 shares of ADC stock. If
the closing value of ADC stock on that day exceeds $4.50 per share, your grant will be
limited to a face value of $1,462,500. The grant price will be ADC's closing price on
the date of grant. One-third of the options will vest on the one-year anniversary of
the grant date and the remaining balance of the options vest in one-eighth (1/8)
increments at each three-month period following the first year anniversary date. The
options will be fully vested on the third year anniversary of the grant. The next time
you may be eligible for a stock option grant under this program is in December 2002.

Restricted
Stock GrantAlso on the last trading day of the month in which
your employment with ADC begins, you will be granted 75,000 shares of restricted stock.
One-third of the restricted stock shares will vest on the one-year anniversary of the
grant date; one-third will vest on the two-year anniversary of the grant date, and the
grant will be fully vested on the three-year anniversary of the grant.

Additional
Stock ProgramsYou will be eligible for ADC's Executive Stock Ownership Program, which
specifies ownership levels expected of ADC officers. The program also provides
additional stock options as part of December annual grants for executives who have
adequate ownership of ADC stock.

For Fiscal Year
2003, you will be eligible for any FY03 Executive Incentive Exchange Program.  Terms of
ADC's FY02 program provide  that eligible participants can exchange up to 50% of their
Management Incentive for stock options - the number of option shares  granted as a result
of the exchange will equal the dollar amount of the MIP award elected to be exchanged
multiplied by 4.5, with  this product being divided by the closing market value of ADC
common stock on the effective date of the grant.

Plan materials
for the Executive Stock Ownership Program and the FY02 Executive Incentive Exchange
Program are enclosed.

Perquisites
You will also be eligible to receive ADC's Executive Perquisites, which
includes an annual payment of $10,000. Currently, perquisite payments are made on a
monthly basis. In July, we anticipate moving to a bi-weekly payment schedule.

Benefits
As a regular full-time employee, you will be eligible to participate in ADC's
complete benefit programs. You will be eligible for coverage under the group medical
plan, dental insurance, life insurance and disability programs. You will be eligible to
enroll in the Global Employee Stock Purchase Plan during the next enrollment period and
to participate in the 401(k) plan. As a participant in the 401(k) plan, following one
year of employment, you will be eligible to receive the company match, which will be
fully vested as of the date of the contribution.

Relocation
Your immediate work location will be ADC's Richardson, Texas site, with
travel to other ADC and customer locations as required to support the business. Within
14 months of your hire date you will be expected to relocate your family residence as
required to most effectively support the business. The specific ADC work location will
be determined at that time by ADC's CEO, taking your recommendation into strong
consideration. Based on the current business profile, your relocation would to be to
Tustin, California or World Headquarters in Eden Prairie, Minnesota.

ADC will
support your relocation in a manner reflective of your executive status with ADC.  This
support will include home sale and  home purchase assistance.  Should your relocation be
to Tustin California, ADC will provide a special relocation provision to  partially
offset the living cost differential between the two locations. Prior to relocating your
family residence, ADC will provide  or reimburse expenses associated with a leased
accommodation in the Tustin area, as well as the limited movement of personal goods,
including an automobile.

Separation
Employment with ADC is for no specific period of time and is at-will. Either
you or ADC is free to terminate this employment relationship at any time, for any
reason, with or without cause.
