                SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN AGREEMENT
                                       FOR
                               WILLIAM J. CADOGAN


       This Agreement made and entered into as of November 1, 1990 by and
between WILLIAM J. CADOGAN and ADC TELECOMMUNICATIONS, INC., a Minnesota
corporation, (hereinafter the "Employer").

                                    SECTION 1

                                  INTRODUCTION

1.1.   Basis of Agreement.  In consideration of the services performed by
WILLIAM J. CADOGAN for the Employer in the past and to be performed in the
future, the Employer hereby agrees to pay, in addition to other consideration to
be provided by the Employer, deferred compensation to him under the terms and
conditions hereinafter set forth.  This Agreement creates an unfunded,
nonqualified plan maintained primarily for the purpose of providing deferred
compensation for a select group of management or highly compensated employees as
contemplated by the Employee Retirement Income Security Act of 1974 ("ERISA")
and shall be construed and administered accordingly.

1.2.   Definitions.  When used herein with initial capital letters, the
following words have the following meanings:

       1.2.1.    Accrued Benefit -- the dollar amount determined for WILLIAM J.
CADOGAN as of the date of his Termination of Employment (and payable monthly to
him in the Single Life Annuity form, beginning on the first day of the calendar
month following his Termination of Employment or age sixty (60) years, if later)
equal to the product of (a) multiplied by (b):

       (a)       Full Supplement.  A dollar amount equal to:

                 (i)     Fifty percent (50%) of his Average Monthly Compensation
                         determined as of the date of his Termination of
                         Employment, minus

                 (ii)    The sum of:  (A) his Qualified Plans Benefit determined
                         as of one day before the date of his Termination of
                         Employment, and (B) fifty percent (50%) of the monthly
                         amount of his Social Security Benefit determined as of
                         one day before the date of his Termination of
                         Employment.

       (b)       Service Ratio.  A fraction, not greater than one (1):

                 (i)     The numerator of which is the total years and fractions
                         of years of his service with the Employer from the
                         Effective Date through and including the date of his
                         Termination of Employment, and

                 (ii)    The denominator of which is eight (8).

       1.2.2.    Actuarial Equivalent -- a benefit of equivalent value computed
on the basis of actuarial tables, factors and assumptions set forth in this
Agreement (including the Appendix - A to this Agreement).

<PAGE>

       1.2.3.    Average Monthly Compensation -- one-sixtieth (1/60th) of the
total dollar amount of Compensation attributable to the sixty (60) consecutive
calendar months ending immediately before WILLIAM J. CADOGAN'S Termination of
Employment subject, however, to the following:

       (a)       Less Than 5 Years.  If he shall have received Compensation
                 attributable to less than all of the sixty (60) consecutive
                 calendar months ending immediately before the Termination of
                 Employment, his Average Monthly Compensation shall be equal to
                 the total of all the Compensation attributable to all calendar
                 months to which any of his Compensation is attributable divided
                 by the greatest number of consecutive calendar months to which
                 any of his Compensation is attributable.

       (b)       Five-Year Limit.  In determining his Average Monthly
                 Compensation, there shall be disregarded all Compensation
                 attributable any calendar months other than the sixty (60)
                 consecutive calendar months ending immediately before the
                 Termination of Employment.

       (c)       No Compensation.  The absence of Compensation in any calendar
                 month shall not affect the requirement that only sixty (60)
                 consecutive calendar months ending immediately before the
                 Termination of Employment be considered in determining Average
                 Monthly Compensation.

       1.2.4.    Board of Directors -- the Board of Directors of the Employer or
a duly authorized committee of less than all the Directors.

       1.2.5.    Change in Control -- an event defined as a Change in Control in
section 7.6.2 of the ADC TELECOMMUNICATIONS, INC. PENSION PLAN (1885
Restatement), as that document and that definition may exist from time to time.

       1.2.6.    Compensation -- amounts paid to WILLIAM J. CADOGAN by the
Employer and all affiliates for services rendered, reported as income subject to
federal income taxes on Treasury Form W-2 for the applicable year; subject,
however, to the following:

       (a)       Excluded Items.  In determining his Compensation, there shall
                 be excluded (i)all discretionary bonuses not paid pursuant to a
                 formal plan, and (ii) all foreign service allowances, foreign
                 tax equalization payments, expense reimbursements, moving
                 expense payments or other similar extra compensation, and (iii)
                 all noncash remuneration and (iv) all deferred compensation
                 (except as provided in (b) below), excess life insurance
                 premiums, the value of stock options (whether or not
                 exercised), and (iv) the value of restricted stock or similar
                 awards and any cash payments made in connection with any such
                 restricted stock award.

       (b)       Added Items.  Remuneration which would have been paid by the
                 Employer or an affiliate but which was not paid because he
                 entered into an agreement to reduce earnings as a condition of
                 participation in a plan established under section 125 or
                 section 401(k) of the Internal Revenue Code, shall be
                 considered to have been paid at the time when it would have
                 been paid but for such agreement to reduce earnings.
                 Remuneration which would have been paid by the Employer or an
                 Affiliate but which was not paid because he entered into an
                 agreement to defer compensation under a nonqualified plan of
                 deferred compensation or under any other similar arrangement
                 (including but not limited to the "Executive Incentive Exchange
                 Plan") shall

                                       -2-

<PAGE>

                 be considered to have been paid at the time it would have been
                 paid but for such agreement to defer earnings.

       (c)       Attribution to Periods.  His Compensation shall be considered
                 attributable to the calendar month in which it is actually paid
                 (and not when earned or accrued) except that annual incentive
                 payments shall be considered attributable to the last day of
                 the last calendar month in the fiscal period with respect to
                 which they are paid.

       (d)       Excluded Periods.  Amounts attributable to calendar months
                 commencing after the earliest of the date he became Disabled or
                 had a Termination of Employment shall not be taken into account
                 in determining his Compensation.

       (e)       Final Payments.  Final payments on account of Termination of
                 Employment (i.e., severance payments) and settlement for
                 accrued but unused vacation and sick leave shall not be taken
                 into account in determining his Compensation.

       1.2.7.    Disability, Disabled -- a medically determinable physical or
mental impairment which constitutes disability under the Employer's separate
long term disability plan.

       1.2.8.    Effective Date -- November 1, 1990.

       1.2.9.    Employer -- ADC TELECOMMUNICATIONS, INC., a Minnesota
corporation, and any successor thereof that adopts this Agreement.

       1.2.10.   Qualified Plans Benefit -- a dollar amount determined for
WILLIAM J. CADOGAN as of the last day of the calendar month in which his
Termination of Employment occurs or, if later, the last day of the calendar
month in which he would attain age sixty (60) years (and expressed in terms of a
monthly annuity payable to him in the Single Life Annuity form beginning on the
first day of the calendar month following his Termination of Employment or, if
later, the first day of the calendar month following the date he would attain
age sixty years) which is the sum of the:

       (a)       accrued benefit developed for him as of the date of his
                 Termination of Employment under all qualified defined benefit
                 pension plans maintained by the Employer when expressed in the
                 form of a Single Life Annuity first payable on the first day of
                 the first calendar month following his Termination of
                 Employment or, if later, the first day of the calendar month
                 following the date he would attain age sixty (60) years; and

       (b)       the Actuarial Equivalent monthly amount of annuity payable to
                 him when expressed in the form of a Single Life Annuity
                 beginning on the first day of the first calendar month
                 following his Termination of Employment or, if later, the first
                 day of the calendar month following the date he would attain
                 age sixty (60) years to the extent such benefits are
                 attributable to contributions of the Employer (and exclusive of
                 any benefits attributable to contributions directly or
                 indirectly made by him) under all qualified defined
                 contribution pension, profit sharing or stock bonus plans
                 maintained by the Employer; and

       (c)       the Actuarial Equivalent monthly amount of annuity payable to
                 him when expressed in the form of a Single Life Annuity
                 beginning on the first day of the first calendar month
                 following his Termination of Employment or, if later, the first
                 day of the calendar month following the date he would attain

                                       -3-

<PAGE>

                 age sixty (60) years to the extent such benefits are Employer-
                 provided benefits payable from a nonqualified plan maintained
                 by the Employer for the purpose of providing benefits which
                 cannot be provided from qualified pension, profit sharing or
                 stock bonus plans maintained by the Employer because of
                 limitations on such plans under section 401(a)(17), section
                 401(k), section 401(m), section 402(g), section 415 and other
                 similar provisions of the Internal Revenue Code.

       1.2.11.   Single Life Annuity -- a form of annuity that is payable
monthly to and for the lifetime of WILLIAM J. CADOGAN, the first such payment to
be due on the date specified in Section 2 hereof and the last such payment due
on the first day of the calendar month in which his death occurs.

       1.2.12.   Social Security Benefit -- the monthly amount available for the
benefit of WILLIAM J. CADOGAN at:

       (a)       at age sixty-two (62) years if his Termination of Employment is
                 before age sixty-two (62) years (calculated on the assumption
                 that he will have no additional earnings from his Termination
                 of Employment until age sixty-two (62) years); or

       (b)       the date of his Termination of Employment if his Termination of
                 Employment is after age sixty-two (62) years but before age
                 sixty-five (65) years; or

       (c)       age sixty-five (65) years, if his Termination of Employment is
                 at or after age sixty-five (65) years;

(excluding amounts available for spouse and dependents) as an old age benefit
under the provisions of Title II of the federal Social Security Act in effect on
the date of the Termination of Employment (or age sixty-five, if earlier),
whether or not payment of such amount is delayed, suspended or forfeited because
of failure to apply, acceptance of other work, or any other similar reason
within his control.  For this purpose, unless he shall have furnished verified
proof of wages before his Termination of Employment, he shall be deemed to have
had taxable wages at or above the taxable wage base in all years prior to the
year of his Termination of Employment.

       1.2.13.   Supplemental Retirement Benefit -- the benefit payable under
this Plan upon the Termination of Employment of WILLIAM J. CADOGAN, subject to
the conditions and limitations set forth in this Plan Statement.

       1.2.14.   Termination of Employment -- a complete severance of WILLIAM J.
CADOGAN'S employment relationship with the Employer and its subsidiaries or
affiliates, if any, for any reason other than his death.  A transfer from
employment with the Employer to employment with an affiliate of the Employer
shall not constitute a Termination of Employment.

1.3.   Rules of Interpretation.  An individual shall be considered to have
attained a given age on his birthday for that age (and not on the day before).
The birthday of any individual born on a February 29 shall be deemed to be
February 28 in any year that is not a leap year.  Notwithstanding any other
provision of this Agreement or any election or designation made under this
Agreement, any individual who feloniously and intentionally kills WILLIAM J.
CADOGAN or any surviving spouse shall be deemed for all purposes of this
Agreement and all elections and designations made under this Agreement to have
died before him or his surviving spouse.  A final judgment of conviction of
felonious and intentional killing is conclusive for the purposes of this
Section.  In the absence of a conviction of felonious and intentional killing,
the Board of Directors shall determine whether the killing was felonious and
intentional for the purposes of this Section.  Whenever appropriate, words used
herein in the singular may be read in the plural, or words used herein in the
plural may be read in the singular; the

                                       -4-

masculine may include the feminine; and the words "hereof," "herein" or
"hereunder" or other similar compounds of the word "here" shall mean and refer
to the entire Agreement and not to any particular paragraph or section of this
Agreement unless the context clearly indicates to the contrary.  The titles
given to the various sections of this Agreement are inserted for convenience of
reference only and are not part of this Agreement, and they shall not be
considered in determining the purpose, meaning or intent of any provision
hereof.  Any reference in this Agreement to a statute or regulation shall be
considered also to mean and refer to any subsequent amendment or replacement of
that statute or regulation.  This instrument has been executed and delivered in
the State of Minnesota and has been drawn in conformity to the laws of that
State and shall, except to the extent that federal law is controlling, be
construed and enforced in accordance with the laws of the State of Minnesota.

       (d)       after, and on account of, his Disability.

and upon the filing of a written application with the Board of Directors, he
shall receive a Supplemental Retirement Benefit.

       2.1.2.    Amount.  The amount of WILLIAM J. CADOGAN'S Supplemental
Retirement Benefit shall be the Actuarial Equivalent single lump sum of his
Accrued Benefit determined as of his Termination of Employment reduced, however,
five-twelfths of one percent (5/12%) for each month by which the payment of the
Supplemental Retirement Benefit precedes the last day of the calendar month in
which he attains age sixty (60) years.

       2.1.3.    Form of Pension.  For the purpose of defining the amount of the
Supplemental Retirement Benefit in Section 2.1.1, the benefit is derived from a
Single Life Annuity, the first payment of which is due on the first day of the
calendar month which follows his Termination of Employment,  or, if later, the
first day of the calendar month which follows the date he would attain age sixty
(60)  years.  Notwithstanding the foregoing, this annuity shall be, in all
cases, converted to an Actuarial Equivalent single lump sum on the first day of
the calendar month following his Termination of Employment (the "Lump Sum
Amount").  The payments (minus all withholding and payroll taxes which must be
deducted therefrom) shall be distributed from this Plan in the same manner as if
it had been paid or commenced from the general assets of the Employer to the
Participant.  Such payment shall be in full and complete discharge of all
benefits payable to, or with respect to the Participant under this Plan
including, but not limited to, all survivor benefits and all optional forms of
benefit to which the Participant or spouse might otherwise have been entitled.
The consent of a spouse or other Beneficiary shall not be required before making
the single lump sum payment or the annual installment payments herein described.
Distribution of benefits accrued on or after April 1, 1996, shall be made in
whichever of the following forms the Participant shall have designated in
writing at the time required by the Employer (to the extent that such election
is consistent with the rules of this Plan Statement).  The Employer shall
unilaterally designate the form of distribution of all benefits accrued prior to
April 1, 1996.

       (a)       Term Certain Installments to Participant.  If the Participant
has elected distribution in a series of annual installments payable over ten
(10) years and the actuarially equivalent single lump sum value of the benefit
at the Termination of Employment is at least One Hundred Thousand Dollars
($100,000), distribution shall be made in a series of annual installments
payable over ten (10) years.

       (b)       Term Certain Installments to Beneficiary.  If the Distributee
                 is the Beneficiary of the Participant who has elected
                 distribution in a series of

                                       -6-

<PAGE>

                 annual installments payable over ten (10)  years and died after
                 Termination of Employment but before distribution commenced and
                 the actuarially equivalent single lump sum value of the benefit
                 at death is at least One Hundred Thousand Dollars ($100,000),
                 distribution shall be made in a series of annual installments
                 payable over ten (10)  years.

       (c)       Continued Term Certain Installments to Beneficiary.  If the
                 Distributee is the Beneficiary of the deceased Participant and
                 distribution had commenced to the deceased Participant before
                 his death over a ten (10) year period as specified in paragraph
                 (a) above, in a series of annual installments payable over the
                 remainder of the ten (10) year period.

       (d)       Lump Sum.  To the extent that the Distributee is either the
                 Participant or the Beneficiary of the deceased Participant and
                 none of the foregoing rules are applicable, in a single lump
                 sum payment.

       2.1.4.    Installment Amounts.  If the Distributee's benefit will be
distributed in the form of a series of annual installments payable over ten (10)
years, a bookkeeping account ("Account") will be created for the purpose of
paying the benefit to the Distributee.  The initial value of the Account shall
equal the Distributee's Lump Sum Account.  The amount of the annual installments
shall be determined by dividing the amount of the Distributee's Account as of
the December 31 as of which the installment is being paid by the number of
remaining installment payments to be made (including the payment being
determined).

       (a)       Valuation and Adjustment of Accounts.  Each Distributee's
                 Account shall be valued as of the last day of each calendar
                 month (the "Valuation Date").  As of each Valuation Date, the
                 value of each Account determined as of the immediately
                 preceding Valuation Date (the "Initial Account Value") shall be
                 increased (or decreased) by the following adjustment made in
                 the following sequence:

                 (i)     The Initial Account Value shall be increased by an
                         amount equal to the balance of the Account as of the
                         preceding Valuation Date  multiplied by the Interest
                         Rate and multiplied by a fraction, the numerator of
                         which is one (1) and the denominator of which is twelve
                         (12); and

                 (ii)    The Initial Account Value (as adjusted above) shall be
                         reduced by the total amount distributed in fact to (or
                         with respect to) the Participant from such Account as
                         of the current Valuation Date.

       (b)       Interest Rate.  For purposes of this Section 2.1, the "Interest
                 Rate" shall mean the rate of interest charged on the Valuation
                 Date for which interest is being credited by Norwest Bank
                 Minnesota, N.A., and in effect on that Valuation Date to its
                 most credit-worthy corporate customers on loans of not more
                 than ninety (90) days duration which are unsecured (that is,
                 the so called prime rate of interest).

       2.1.5.    Default.  If for any reason a Participant shall have failed to
make a timely written designation of form for distribution (including reasons
entirely beyond the control of the Participant), the distribution shall be made
in a single lump sum.  No spouse, former spouse or other person shall have any
right to participate in the Participant's selection of a form of benefit.

       2.1.6.    Time.  Any lump sum payment shall be made as of the first day
of the calendar month following the Participant's Termination of Employment and
actual payment shall be made as soon as administratively feasible thereafter.
Any annual installment payments shall be commenced as of the December 31
coincident with or next following the Participant's Termination of Employment
and actual payment shall be commenced as soon as

                                       -7-

<PAGE>

administratively feasible thereafter.  If the Employer determines that delaying
the time the initial payments are made or commenced would increase the
probability that such payments would be fully deductible for federal or state
income tax purposes, for example because such payments would result in over one
million dollars ($1,000,000) of compensation for the taxable year with respect
to the Participant under section 162(m) of the Code, the Employer may
unilaterally delay the time of the making payment or transfer for up to twenty-
four (24) months after the date such payment or transfer would otherwise be
payable.

2.2.   Designation of Beneficiaries for Installment Payments.  This section 2.2
applies only to Participants who are entitled to receive a distribution in the
form of annual installments and who have elected to receive distribution of the
Participant's benefit in the form of annual installments.

       2.2.1.    Right To Designate.  Each Participant may designate, upon forms
to be furnished by and filed with the Employer, one or more primary
Beneficiaries or alternative Beneficiaries to receive all or a specified part of
such Participant's account in the event of such Participant's death.  The
Participant may change or revoke any such designation from time to time without
notice to or consent from any Beneficiary, except as provided in Section2.2.6.
No such designation, change or revocation shall be effective unless executed by
the Participant and received by the Employer during the Participant's lifetime.

       2.2.2.    Failure of Designation.  If a Participant:

       (a)       fails to designate a Beneficiary,

       (b)       designates a Beneficiary and thereafter revokes such
                 designation without naming another Beneficiary, or

       (c)       designates one or more Beneficiaries and all such Beneficiaries
                 so designated fail to survive the Participant,

such Participant's account, or the part thereof as to which such Participant's
designation fails, as the case may be, shall be payable to the first class of
the following classes of automatic Beneficiaries with a member surviving the
Participant and (except in the case of surviving issue) in equal shares if there
is more than one member in such class surviving the Participant:

       Participant's surviving spouse
       Participant's surviving issue per stirpes and not per capita
       Participant's surviving parents
       Participant's surviving brothers and sisters
       Representative of Participant's estate.

       2.2.3.    Disclaimers by Beneficiaries.  A Beneficiary entitled to a
distribution of all or a portion of a deceased Participant's account may
disclaim an interest therein subject to the following requirements.  To be
eligible to disclaim, a Beneficiary must be a natural person, must not have
received a distribution of all or any portion of the account at the time such
disclaimer is executed and delivered, and must have attained at least age
twenty-one (21) years as of the date of the Participant's death.  Any disclaimer
must be in writing and must be executed personally by the Beneficiary before a
notary public.  A disclaimer shall state that the Beneficiary's entire interest
in the undistributed account is disclaimed or shall specify what portion thereof
is disclaimed.  To be effective, duplicate original executed copies of the
disclaimer must be both executed and actually delivered to the Employer after
the date of the Participant's death but not later than one hundred eighty (180)
days after the date of the Participant's death.  A disclaimer shall be
irrevocable when delivered to the Employer.  A disclaimer shall be considered to
be delivered to the Employer only when actually received by the Employer.  The
Employer shall be the sole judge of the content, interpretation and validity of
a purported disclaimer.  Upon the filing of a valid disclaimer, the Beneficiary
shall

                                       -8-

<PAGE>

be considered not to have survived the Participant as to the interest
disclaimed.  A disclaimer by a Beneficiary shall not be considered to be a
transfer of an interest in violation of the provisions of Section 8 and shall
not be considered to be an assignment or alienation of benefits in violation of
federal law prohibiting the assignment or alienation of benefits under this
Plan.  No other form of attempted disclaimer shall be recognized by the
Employer.

       2.2.4.    Definitions.  When used herein and, unless the Participant has
otherwise specified in the Participant's Beneficiary designation, when used in a
Beneficiary designation, "issue" means all persons who are lineal descendants of
the person whose issue are referred to, including legally adopted descendants
and their descendants but not including illegitimate descendants and their
descendants; "child" means an issue of the first generation; "per stirpes" means
in equal shares among living children of the person whose issue are referred to
and the issue (taken collectively) of each deceased child of such person, with
such issue taking by right of representation of such deceased child; and
"survive" and "surviving" mean living after the death of the Participant.

       2.2.5.    Special Rules.  Unless the Participant has otherwise specified
in the Participant's Beneficiary designation, the following rules shall apply:

       (a)       If there is not sufficient evidence that a Beneficiary was
                 living at the time of the death of the Participant, it shall be
                 deemed that the Beneficiary was not living at the time of the
                 death of the Participant.

       (b)       The automatic Beneficiaries specified in Section 3.4.2 and the
                 Beneficiaries designated by the Participant shall become fixed
                 at the time of the Participant's death so that, if a
                 Beneficiary survives the Participant but dies before the
                 receipt of payments due such Beneficiary hereunder, such
                 payments shall be payable to the representative of such
                 Beneficiary's estate.

       (c)       If the Participant designates as a Beneficiary the person who
                 is the Participant's spouse on the date of the designation,
                 either by name or by relationship, or both, the dissolution,
                 annulment or other legal termination of the marriage between
                 the Participant and such person shall automatically revoke such
                 designation.  (The foregoing shall not prevent the Participant
                 from designating a former spouse as a Beneficiary on a form
                 executed by the Participant and received by the Employer after
                 the date of the legal termination of the marriage between the
                 Participant and such former spouse, and during the
                 Participant's lifetime.)

       (d)       Any designation of a nonspouse Beneficiary by name that is
                 accompanied by a description of relationship to the Participant
                 shall be given effect without regard to whether the
                 relationship to the Participant exists either then or at the
                 Participant's death.

       (e)       Any designation of a Beneficiary only by statement of
                 relationship to the Participant shall be effective only to
                 designate the person or persons standing in such relationship
                 to the Participant at the Participant's death.

A Beneficiary designation is permanently void if it either is executed or is
filed by a Participant who, at the time of such execution or filing, is then a
minor under the law of the state of the Participant's legal residence.  The
Employer shall be the sole judge of the content, interpretation and validity of
a purported Beneficiary designation.

       2.2.6.    Spousal Rights.  No person designated to be a Beneficiary,
other than a spouse or surviving spouse, shall have any rights or interest in
the benefits accumulated under

                                       -9-

<PAGE>

this Plan including, but not limited to, the right to be the sole Beneficiary or
to consent to the designation of Beneficiaries (or the changing of designated
Beneficiaries) by the Participant.

       Notwithstanding the foregoing, a designation will not be valid for the
purpose of paying benefits from the Plan to anyone other than a surviving spouse
of the Participant (if there is a surviving spouse) unless that surviving spouse
consents in writing to the designation of another person as Beneficiary.  To be
valid, the consent of such spouse must be in writing, must acknowledge the
effect of the designation of the Beneficiary and must be witnessed by a notary
public.  The consent of the spouse to a Beneficiary is not a waiver of any
rights to pre-retirement death benefits under the Plan because a Beneficiary
designation under this Section2.2 is only effective for annual installment
payments due after the Participant's termination of employment.  The consent of
the surviving spouse need not be given at the time the designation is made.  The
consent of the surviving spouse need not be given before the death of the
Participant.  The consent of the surviving spouse will be required, however,
before benefits can be paid to any person other than the surviving spouse.  The
consent of a spouse shall be irrevocable and shall be effective only with
respect to that spouse.

2.3.   No Other Benefits.  No benefits are available under this Plan upon the
Termination of Employment of WILLIAM J. CADOGAN before he is entitled to the
Supplemental Retirement Benefit specifically enumerated herein.

2.4.   Facility of Payment.  In case of the legal disability, including
minority, of WILLIAM J. CADOGAN, joint annuitant or beneficiary entitled to
receive any distribution under the Agreement, payment shall be made, if the
Board of Directors shall be advised of the existence of such condition:

       (a)       to his or her duly appointed guardian, conservator or other
                 legal representative, or

       (b)       to a person or institution entrusted with the care or
                 maintenance of the incompetent or disabled person, provided
                 such person or institution has satisfied the Board of Directors
                 that the payment will be used for the best interest and assist
                 in the care of such person, and provided further, that no prior
                 claim for said payment has been made by a duly appointed
                 guardian, conservator or other legal representative of such
                 person.

Any payment made in accordance with the foregoing provisions of this section
shall constitute a complete discharge of any liability or obligation of the
Employer and the Board of Directors.

2.5.   Forfeiture of Benefits.  All unpaid benefits under this Plan payable to
or with respect to WILLIAM J. CADOGAN, including without limiting the generality
of the foregoing, undistributed commuted values, shall be immediately and
permanently forfeited upon the determination by the Board of Directors that he,
either before or after Termination of Employment:

                 (i)     engaged in a felonious or fraudulent conduct resulting
                         in material harm to the Employer or an affiliate; or

                (ii)     made an unauthorized disclosure to a competitor of any
                         material confidential information, trade information,
                         or trade secrets of the Employer or an affiliate; or

               (iii)     provided the Employer or an affiliate with materially
                         false reports concerning his business interests or
                         employment; or

                (iv)     made materially false representations which are relied
                         upon by the Employer or an affiliate in furnishing
                         information to shareholders,

                         Exchange Commission or public or private regulatory
                         body; or

                 (v)     maintained an undisclosed, unauthorized and material
                         conflict of interest in the discharge of the duties
                         owed by him to the Employer or an affiliate; or

                (vi)     engaged in conduct causing a serious violation of state
                         or federal law by the Employer or an affiliate; or

               (vii)     engaged in the theft of assets or funds of the Employer
                         or an affiliate; or

              (viii)     has been convicted of any crime which directly or
                         indirectly arose out of his employment relationship
                         with the Employer or an affiliate or materially
                         affected his ability to discharge the duties of his
                         employment with the Employer or an affiliate; or

                (ix)     engaged during his employment in any employment or
                         self-employment with a competitor of the Employer or an
                         affiliate; or

                 (x)     engaged during a period of two (2) years after his
                         voluntary termination of employment with the Employer
                         in any employment or self-employment with a competitor
                         of the Employer or an affiliate within the geographical
                         area which is then served by the Employer or the
                         affiliate.

He shall be notified within thirty (30) days of any such decision by the Board
of Directors.  He may contest such action by filing a claim as prescribed in
Section6.4.

                                    DEATH BENEFITS
                                           
3.1.  Death Before Benefit Commencement.

      3.1.1.    When Available.  If upon the death of WILLIAM J. CADOGAN:

      (a)       his Supplemental Retirement Benefit under the Agreement had not
                been paid as provided in Section 2.1, and

      (b)       he was married and had been married for the one (1) year
                preceding his death, and

      (c)       he was entitled to some Accrued Benefit immediately before his
                death;

a lump sum survivor benefit shall be payable to the surviving spouse to whom he
was married for at least one (1) year ending on the date of death.

      3.1.2.    Amount.  The amount of the lump sum survivor benefit shall be:

      (a)       If he had not Terminated Employment at the date of his death,
                the amount shall be the 85% of Actuarially Equivalent single
                lump sum which he would have received if he had Terminated
                Employment on the date of his death at the written request of
                the Board of Directors (and not by reason of his death).

      (b)       If he had Terminated Employment at the date of his death, the
                amount shall be the amount, if any, which he would have
                received, if any, under Section 2.1 if he had lived to the date
                of such payment.

      3.1.3.    Form of Benefit.  The lump sum  survivor benefit shall be due
on the first day of the calendar month after the death of WILLIAM J. CADOGAN. 
Notwithstanding the foregoing, if that lump sum is equal to or greater than One
Hundred Thousand Dollars ($100,000) and the Participant has elected to receive
his benefit in annual installment payments, it shall be held in the Account
which is established under the Plan for the purpose of making payments in a
series of annual installments payable over ten (10) years and distributed from
the Plan to the surviving spouse in accordance with the rules under Section 2.1.
The benefit payment or payments (minus the withholding and payroll taxes which
must be deducted therefrom) shall be paid to the surviving spouse from the
general assets of the Employer.  No other death benefit shall be payable with
respect to him if he dies under these circumstances.  No death benefit shall be
payable with respect to him if he dies under any other circumstances.

4.1.  Unfunded Agreement.  All benefits payable under this Agreement shall be
paid exclusively from the general assets of the Employer.  No fund or trust
shall be established apart from the general assets of the Employer for the
purposes of this Agreement.  No assets or property shall be segregated or set
apart from the general assets of the Employer for the purpose of funding this
Agreement.  The rights of WILLIAM J. CADOGAN under this Agreement (or of any
surviving spouse with respect to him) shall be solely those of an unsecured
general creditor of the Employer.  If, for its own internal purposes, the
Employer elects to purchase life insurance policies on his life or any other
assets in connection with this Agreement, he will not be the beneficial owner or
beneficiary of such policies or assets (all such rights being retained by the
Employer) and shall not have any preferred claim or interest in any such
policies, assets or the proceeds thereof.  The Employer makes no representation
that it will actually use any life insurance policies, other assets or proceeds
of the same which it may acquire for the purpose of paying any benefits under
this Agreement.

4.2.  Spendthrift Provisions.  Neither WILLIAM J. CADOGAN nor his surviving
spouse shall have any transferrable interest in any benefit nor shall he or his
surviving spouse have any power to anticipate, alienate, dispose of, pledge or
encumber the same nor shall the Employer or the Board of Directors recognize any
assignment thereof, either in whole or in part, nor shall it be subject to
attachment, garnishment, execution following judgment or other legal process.

      (d)       A claimant may be represented by a lawyer or other
                representative (at their own expense), but the Board of
                Directors reserves the right to require the claimant to furnish

                        DETERMINATION OF ACTUARIAL EQUIVALENT
                                TO SINGLE LIFE ANNUITY


    Section 1.     Lump Sum Settlements.  When converting benefits to a single
lump sum for payment to WILLIAM J. CADOGAN, the benefit to be converted is the
Single Life Annuity form payable at the latest date such benefit may commence. 
When converting benefits to a single lump sum for payment to any other person,
the benefit to be converted shall be the benefit payable to such other person at
the latest date such benefit may commence.  The factors to be used to convert
the Single Life Annuity form to a lump sum benefit shall be:

Interest Assumption:    During each stability period, the annual rate of
                        interest on 30-year Treasury securities for the
                        lookback month.  The stability period shall be the Plan
                        Year.  The lookback month shall be the second calendar
                        month preceding the commencement of the stability
                        period.

Mortality Assumption:   The mortality rate determined from the table prescribed
                        by the Secretary of the Treasury under section
                        417(e)(3)(A)(ii)(I) of the Code based on the prevailing
                        commissioners' standard table used to determine
                        reserves for group annuity contracts.

    Section 2.  Defined Contribution Plan Accrual.  To determine the Actuarial
Equivalent annuity value of WILLIAM J. CADOGAN'S account balances attributable
to contributions of the Employer in defined contribution plans as of a specified
date (expressed in the Single Life Annuity form beginning on the first day of
the calendar month following his Normal Retirement Age) the following steps
shall be followed:

    (a)    Determine the value of all such defined contribution plan accounts
           as of the valuation date under each defined contribution plan which
           is coincident with or immediately preceding such specified date;

    (b)    Increase such account balances from such valuation dates to the last
           day of the calendar month in which his Termination of Employment
           occurs or, if later, the last day of the calendar month in which he
           would attain age sixty (60) years at an assumed rate of earnings
           equal to eight percent (8%), compounded annually;

    (c)    Convert the resulting total to an Actuarial Equivalent amount of
           monthly annuity in the Single Life Annuity form commencing on the
           last day of the calendar month in which his Termination of
           Employment occurs or, if later, the last day of the calendar month
           in which he would attain age sixty (60) years by applying the
           interest and mortality factors set forth in Section 1 above.

    Section 3.     General Factors.  Except to the extent otherwise specified
in the Agreement, the following interest and mortality factors shall be used in
determining the Actuarial Equivalent amount of any benefit:

Interest Assumption:    During each stability period, the annual rate of
                        interest on 30-year Treasury securities for the
                        lookback month.  The

                        stability period shall be the Plan Year.  The lookback
                        month shall be the second calendar month preceding the
                        commencement of the stability period.

Mortality Assumption:   The mortality rate determined from the table prescribed
                        by the Secretary of the Treasury under section
                        417(e)(3)(A)(ii)(I) of the Code based on the prevailing
                        commissioners' standard table used to determine
                        reserves for group annuity contracts.
