                              PREAMBLE
                              --------

     The purpose of this Mallinckrodt Income Deferral Plan (the
"Plan") is to provide opportunities for a select group of management
or highly compensated employees of Mallinckrodt Inc. (the "Company")
and its Affiliates to defer, on a nontaxable basis, the receipt of
income pursuant to Section 451 of the Internal Revenue Code.  The Plan
will be effective as of January 1, 2000 as noted below.

     The Company declares its intention is to create an unfunded Plan
primarily for the purpose of providing a select group of management or
highly compensated employees of the Company and of its affiliated
organizations with deferred compensation in accordance with their
individual elections.  It is also the intention of the Company that
the Plan be an "employee pension benefit plan" as defined in Section
3(2) of Title I of the Employee Retirement Income Security Act of 1974
("ERISA") and that the Plan be the type of plan described in Sections
201(2), 301(3) and 401(a)(1) of Title I of ERISA.  The Committee, as
defined herein, is the "named fiduciary" of the Plan for purposes of
Section 402(a)(2) of ERISA.

     Accordingly, the following Plan is adopted with respect to each
such Compensation Deferral.

or Inactive Participant's Account thereon shall be credited to a
separate Subaccount within Participant's Account.  Separate
Subaccounts shall be created in each Participant's Account based upon
the dates or events upon which Compensation Deferrals and investment
returns thereon will be paid.  Amounts deferred to common payment
dates or events will be combined into a single Subaccount.  All
investment return, income gain or loss associated with a Compensation
Deferral which is credited to a particular Subaccount shall likewise
be credited to such Subaccount.

                              ARTICLE II
                    ELIGIBILITY AND PARTICIPATION
                    -----------------------------

     2.1    Eligibility for Participation.  Each Employee may
            -----------------------------
participate in the Plan as soon as practicable after the date on which
the Employee meets the definition of Eligible Employee hereunder, is
notified of his eligibility for participation and becomes eligible to
defer receipt of Compensation under a plan described in Section 1.10.

     2.2    Application.  Participation in the Plan is voluntary.  In
            -----------
order to participate, an otherwise Eligible Employee must make written
application and must complete such application process, including a
Participant Enrollment and Election Form, as required by Section 3.1
and as prescribed by the Plan Administrator.  The application process
shall require an Eligible Employee to:  (a) specify a rate or amount
of Compensation Deferral, (b) authorize the Company to reduce and

will be made or when payment of Compensation that has been deferred
will be made (as required by Article VI) and the manner of payment (as
required by Article VII).

            ------------
Company and its Affiliates is terminated is subsequently reemployed,
he or she shall become a Participant in accordance with the provisions
of this Article when he or she again becomes an Eligible Employee.

but ceases to be an Eligible Employee, he or she shall not be eligible
to make further Compensation Deferrals hereunder, but shall become an
Inactive Participant.

                              ARTICLE III
                       CONTRIBUTIONS AND CREDITS
                       -------------------------

     3.1    Participant Compensation Deferrals.  In accordance with
            ----------------------------------
rules established by the Committee and Plan Administrator, a
Participant may elect to defer Compensation that is due to be earned
and that would otherwise be paid or payable to the Participant.  The
Plan Administrator will establish, in its discretion, the increments
in which Compensation Deferrals may be made, along with applicable
minimum Compensation Deferral.  The maximum amount of Compensation
which a Participant may defer under the Plan shall be one hundred
percent (100%) of any award(s) which a Participant receives under any
of the incentive compensation programs of the Company, described in
Section 1.10.

     3.2    Election of Compensation Deferrals.  (a) Participants
            ----------------------------------
shall be entitled to make a separate Compensation Deferral election
for each award of Compensation made for each year under each of the
incentive plans described in Section 1.10, unless otherwise provided
by such plan or the Committee.  For each award of Compensation that a
Participant elects to defer under this Plan, he or she shall complete
a Participant Enrollment or Election Form electing the percentage or
dollar amount of such Compensation award which the Participant elects
to defer.  All elections to defer Compensation must be made before
such dates as established by the Plan Administrator and all
Compensation Deferral elections must be completed prior to the date on
which such Compensation award is finally established, due and payable
under any plan described in Section 1.10 for which the Deferral
election is being made.  Compensation Deferral elections made for any
award(s) under any such incentive plan shall not be effective for or
carry over to later Plan Years or other awards except as specified in
the actual election forms.  Each Compensation Deferral election shall
also provide the date or event upon which payment of the Compensation
Deferral and accumulated investment return thereon will commence (as
required by Article VI) and will select the manner in which each such
Compensation Deferral and accumulated investment return thereon will
be paid (as required by Article VII).  All Compensation Deferral
elections will be irrevocable once made, must be in writing and must
be prepared pursuant to such rules and procedures as established by
the Plan Administrator; however, Participants shall be permitted to
change the manner in which Compensation Deferrals, and investment
returns credited thereon to any Subaccount, are to be paid and may
select a different distribution election form as specified in Section
7.1 with respect to the entire amount credited to any Subaccount in
accordance with rules established by the Plan Administrator.

     (b)    Compensation Deferrals shall be deducted by the Company
from the Compensation of a deferring Participant and shall be credited
to the Plan Account of that Participant.

     3.3    Merger of Prior Deferred Compensation Balances.  Plan
            ----------------------------------------------
Participants and Inactive Participants who prior to the Effective Date
of this Plan had previously deferred receipt of compensation under
Company incentive compensation plans and who still have accumulated,
unpaid balances due and owing to them under those plans, shall be
permitted to elect to have such unpaid balances transferred to this
Plan.   Elections to transfer balances to this Plan will be
irrevocable once made, must be in writing and will be permitted in
accordance with such rules and procedures as established by the Plan
Administrator.   Any balances transferred to this Plan will be
governed, and may be managed by Participants and Inactive
Participants, in all respects according to the terms of this Plan.  In
addition, Participants and Inactive Participants shall not be
permitted to make any changes in the timing and payment of transferred
balances except as provided in Section 7.1 regarding the manner of
payment and Article VIII concerning beneficiary designation.

                         ALLOCATION OF FUNDS
                         -------------------

     4.1    Compensation Deferral Accounts.  The Company shall
            ------------------------------
establish and maintain on its books of account for each Participant in
the Plan a separate Plan Account.  The balance to the credit of each
Participant in their Plan Account shall be his or her entire
entitlement and benefit under this Plan.

     4.2    Vesting of Account Balances.  Each Participant shall be
            ---------------------------
fully vested at all times in the entire balance to the Participant's
credit in his or her Account and such Account balance shall be
nonforfeitable and shall not be reduced except for distributions,
withdrawals and investment performance or to properly correct any
error or state any Plan transaction as determined appropriate by the
Plan Administrator.

     4.3    Crediting of Account Balances.  The Account and
            -----------------------------
Subaccounts of each Participant shall be credited and debited at such
times and in such manner as determined appropriate by the Plan
Administrator and the Committee with amounts equal to: (a) the
Participant's Compensation Deferrals, (b) any deemed investment
return, income, gains or losses determined by the Administrator to be
allocable to the Participant's prior Compensation Deferrals and
Account balance, (c) distributions or withdrawals from the
Participant's Account and (d) any other adjustments determined to be
appropriate by the Administrator or the Committee.

     4.4    Investment Subaccounts.  Each Account shall, to the extent
            ----------------------
determined appropriate by the Plan Administrator, be comprised of one
or more investment subaccounts to which all Compensation Deferrals
under the Plan and deemed investment return income, gain or loss
allocated thereon will be credited according to each Participant's
deemed investment directions, or pursuant to any mandatory deemed
investment directions made by the Committee.  Investment Subaccounts
shall be established based upon the dates and events on which
Compensation deferrals and investment returns thereon are to be paid
as described in Section 1.1.  Deemed investment return income, gains
or losses from the Hypothetical Investment Funds for which each
investment subaccount is established will be credited or debited to
that investment subaccount as described in Section 1.1.

     4.5    Investment Return and Subaccount Allocations.  The
            --------------------------------------------
Committee and Plan Administrator will have complete discretion to
allocate any deemed investment return, income, gains or losses among
Plan Accounts and subaccounts pursuant to such allocation rules or
methods as the Committee and Administrator deem to be appropriate.

     4.6    Unless the context does not allow, all references to
Participants in this Article shall also refer to Inactive
Participants.

                              ARTICLE V
       CREDITING OF DEEMED INVESTMENT RETURN ON COMPENSATION
               DEFERRALS AND COMMON STOCK DEFERRALS
       ------------------------------------------------------

     5.1    Investment Return.  The Company is not obligated in any
            -----------------
manner to actually invest Compensation Deferrals credited to
Participant Accounts in any actual or separate investment or fund of
any kind.  To the extent Compensation Deferrals are invested in any
investment or fund, the investment return, income, gain or loss from
such investment shall be the property of the Company, or Trust if one
is established under this Plan to hold its assets.  The Committee
shall determine in its discretion the amount, if any, of any
investment return, income, gain or loss to be credited or debited to
all Participant Accounts.  The Committee may change, at any time, the
manner and method in which future investment return, income, gain or
loss, if any, may be credited to Participant Accounts.

     5.2    Investment Funds.  The Committee may, from time to time,
            ----------------
establish and maintain, or cause to be established and maintained,
Hypothetical Investment Funds.  Each such Hypothetical Investment Fund
shall be deemed to carry a rate of investment return or produce
income, gains or losses, as determined by the Committee consistent
with Section 1.16.

     5.3    Hypothetical Investment Fund Directions of Participants.
            -------------------------------------------------------
To the extent the Committee creates Hypothetical Investment Funds,
Participants may direct the Company and Administrator as to how the
amounts credited to his or her Plan Account and Subaccounts shall be
deemed to be invested in and allocated among such Hypothetical
Investment Funds.   Such directions shall be made at such times and
intervals and shall be subject to such operating rules and procedures
as may be established from time to time by the Committee or the Plan
Administrator.  Such directions shall designate the percentage (in any
whole percent multiples) that the Participant requests of each of the
Participant's Subaccounts to be deemed invested in each such
Hypothetical Investment Fund as may then be available and shall,
unless otherwise provided by the Plan Administrator, be subject to the
following rules:

     (a)    A Participant may make a separate deemed investment
election among Hypothetical Investment Funds for each of the
Participant's Subaccounts.

     (b)    Any initial or subsequent Hypothetical Investment Fund
direction shall be provided on such form and in such manner as
directed by the Administrator and shall be effective on the first day
following the Valuation Date on or prior to which such directions are
provided, subject to such procedures and practices adopted by the
Administrator.

     (c)    All Compensation Deferrals and accumulated investment
return income, gain or loss thereon credited to a Participant's
Subaccount shall be deemed to be invested in accordance with the then
effective Hypothetical Investment Fund direction for that Subaccount.
An election concerning Hypothetical Investment Fund directions shall
continue indefinitely as provided in the Participant's most recent
Participant Enrollment and Election Form or other form specified by
the Administrator.  As of the effective date of any new deemed
Investment Fund direction, all of the Participant's Compensation
Deferrals credited to the Participant's Account and particular
Subaccount after that date shall be allocated among the designated
Hypothetical Investment Funds according to the percentages specified
in the new deemed investment direction unless and until a subsequent
deemed investment direction shall be filed and become effective.

     (d)    In accordance with uniform rules and practices developed
by the Plan Administrator, Participants shall also be permitted to
reallocate their existing Account and Subaccount balances among other
Hypothetical Investment Funds to be deemed invested in those Funds in
such percentages and as of such Valuation Dates as specified by the
Plan Administrator.

     (e)    If the Administrator receives an initial or revised deemed
investment direction that it deems to be incomplete, unclear, or
improper, the Participant's investment direction then in effect shall
remain in effect (or, in the case of a deficiency in an initial deemed
investment direction, the Participant shall be deemed to have filed no
deemed investment direction) unless the Administrator provides for,
and permits the application of, corrective action prior thereto.

     (f)    If the Administrator possesses at any time directions as
to the deemed investment of less than all of a Participant's Account,
the Participant shall be deemed to have directed that the undesignated
portion of the Account be deemed to be invested in such Hypothetical
Investment Fund under the Plan as determined by the Administrator in
its discretion.

     (g)    Each Participant hereunder, as a condition to his or her
participation, agrees to indemnify and hold harmless the Company, the
Trustees, the Plan Administrator and its agents and representatives
from any losses or damages of any kind relating to the deemed
investment of the Participant's Account hereunder.

     5.4    Common Stock Deferrals and Hypothetical Common Stock
            ----------------------------------------------------
Investment Fund.  If a Participant makes a Compensation Deferral under
---------------
an incentive compensation plan, as described in Section 1.10, which
Compensation would otherwise have been paid in Common Stock, then the
Compensation Deferral will be credited in shares of Common Stock to a
Participant subaccount as described in Sections 1.1 and 5.3 and will
be invested in the Hypothetical Common Stock Investment Fund.  In
addition, Participants may direct investment of Compensation
Deferrals, which would otherwise be paid in cash, to the Hypothetical
Common Stock Investment Fund, as well as any other portion of the
Participant's Account balance.  Such Fund and Compensation Deferrals
deemed to be invested therein will be operated and accounted for in
accordance with the following and such other rules as may be developed
by the Plan Administrator:

     (a)    For record-keeping purposes only, Participant Compensation
Deferral subaccounts shall be maintained in numbers of hypothetical
shares of Common Stock for Compensation Deferrals, or other Account
balances, deemed invested in the Common Stock Investment Fund.

     (b)    In determining the number of hypothetical shares of Common
Stock to be credited to a Participant's Account for each Compensation
Deferral which would otherwise have been paid in cash, as well as
other Account balances directed to the Hypothetical Common Stock Fund,
the number of shares will be determined by dividing the cash amount of
the Compensation Deferral or value of other Account balances directed
to such Fund, by the average of the high and low prices of the
Company's Common Stock on the New York Stock Exchange on the award
date or, for transfers of all or a portion of an Account balance, on
the Valuation Date on which a transfer of existing Account Balance to
the Fund is deemed to have occurred.  With respect to Participants who
make Compensation Deferrals of awards which would otherwise have been
paid in Common Stock, their Accounts will be credited with the number
of shares granted in the award.

     (c)    Any Compensation Deferrals made or Account balances deemed
invested in the Hypothetical Common Stock Investment Fund will earn a
credit on and as of the record date for payment of any dividends
equivalent to any dividend which would have been payable with respect
to the number of hypothetical shares of the Company's Common Stock
which, as of the record date for the dividend, had been credited to
the Participant as though such shares had actually been issued and
outstanding ("Dividend Equivalent").  All such Dividend Equivalents
will be credited to a Participant's Account in cash and will then be
deemed to have been reinvested in Common Stock at the average of the
high and low prices of the Company's Common Stock on the New York
Stock Exchange on the record date.

     (d)    If a stock dividend, stock split, recapitalization, or
other transaction results in a change in the number of outstanding
shares of Common Stock of the Company, the Committee shall make such
adjustment, if any, as may be equitable in the number of shares which
are credited to a Participant's Account.  The determination of the
Committee on these matters shall be final and conclusive and binding
on the Company and all Participants and Inactive Participants.

     (e)    Account balances credited with shares of Common Stock
under the Hypothetical Common Stock Investment Fund will be
distributed in cash at the same time and in the same manner as would
apply to distribution of Accounts under Article VII.

     5.5    Account Valuations.  Participant Accounts will be valued

            ------------------
by the Administrator as of each Valuation Date and the Administrator
shall have the ability to designate interim valuation dates as it
determines appropriate.

     5.6    Unless the context does not allow, all references to
Participants in this Article V shall also refer to Inactive
Participants.


                              ARTICLE VI
              TIME FOR DISTRIBUTION OF ACCOUNT BALANCES
              -----------------------------------------

     6.1    Time for Distribution of Accounts.  At the time a
            ---------------------------------
Participant elects to make a Compensation Deferral under the Plan and
in accordance with procedures prescribed by the Plan Administrator,
the Participant shall elect, with respect to each Compensation
Deferral and all investment return, income, gain or loss credited to
Participant's Account thereon, the date on which payment of such
Compensation Deferral and accumulated investment return thereon shall
commence as well as the manner and method of distribution of such
amounts.  Each Participant must elect to have payment of each such
Compensation Deferral, and associated accumulated investment return,
income, gain or loss thereon, commence upon any one of the following
events: (a) the Participant's attaining Normal Retirement Age, (b) the
Participant's attaining an Early Retirement Age, (c) the Participant's
termination of employment with the Company and all of its Affiliates,
or (d) following expiration of a fixed term of years after the Plan
Year for which a Compensation Deferral is elected.  Such elections
shall, once made, be irrevocable, and may not be altered; provided,
however, that Participants and Inactive Participants shall be
permitted to change the manner in which Compensation Deferrals and
investment return credited thereon to any Subaccount are to be paid
and may elect a different distribution election form as specified
below with respect to the entire amount credited to any Subaccount.

     6.2    Death.  If a Participant or Inactive Participant dies
            -----
before payments from his or her Account commence, his or her
Beneficiary will receive benefits in the form of payment that the
Participant had elected, commencing as soon as practicable after the
Participant's death.  If no election was made for an Account or
portions thereof, the Account will be distributed to the Participant's
Beneficiary in a lump sum.  If a Participant or Inactive Participant
dies after payments for his Account have commenced, his Beneficiary
will receive the unpaid balance of the Account in the same manner in
which the Participant was receiving such amounts.  A Participant or
Inactive Participant may designate a separate Beneficiary for each
separate Compensation Deferral made and associated investment return,
income, gain or loss thereon.  Following a Participant's or Inactive
Participant's death, the Participant's Beneficiary may designate a
successor Beneficiary to receive any remaining payments in the event
of the Beneficiary's death before all payments are made.

     6.3    Disability.  Notwithstanding any distribution or deferral
            ----------
election otherwise made under this Plan, if the employment of a
Participant or Inactive Participant with the Company and its
Affiliates terminates because of disability (as defined in the
Company's long term disability plan applicable to its salaried
employees), the Participant's or Inactive Participant's Account

              MANNER OF DISTRIBUTION OF ACCOUNT BALANCES
              ------------------------------------------

     7.1    Methods of Distribution of Accounts.  At the time a
            -----------------------------------
Participant elects to make a Compensation Deferral under the Plan, the
Participant shall elect, in accordance with uniform rules developed by
the Plan Administrator, with respect to each Compensation Deferral and
all investment return, income, gain or loss credited to Participant's
Account thereon, the manner and method of distribution of such
amounts.  Participants and Inactive Participants shall be permitted to
change the manner in which Compensation Deferrals and investment
return credited thereon to any Subaccount are to be paid and may
select a different distribution election form as specified below with
respect to the entire amount credited to any Subaccount.  A
Participant must select one of the following forms for payment of each
Compensation Deferral made under this Plan and the investment return,
income, gain or loss credited thereon:

     (a)    A lump sum cash payment to be made not later than sixty
(60) days following the event or date giving rise to the right to
receive a distribution, or

     (b)    In a series of not less than five (5) nor more ten (10)
annual installments to be made commencing not later than sixty (60)
days following the event or date giving rise to the right to receive a
distribution.

     7.2    Distribution in Cash.  All amounts paid under this Plan
            --------------------
with respect to all Account balances, regardless of the nature of the
Hypothetical Investment Fund in which such balances were deemed to be
invested, shall be payable in cash.

     7.3    Valuation of Distributions.  With respect to any Account
            --------------------------
balance and distribution to be paid under this Plan, the value of such
distribution shall be determined as of the Valuation Date coinciding
with or next following the event or date giving rise to the right to
receive a distribution under the Plan has occurred and after all of
the following also have occurred:  (a) the Participant or Inactive
Participant has provided the Plan Administrator such notice of the
distribution, if any, as may be required, (b) the Participant has
tendered such documents as prescribed by the Administrator, (c) the
Plan Administrator has properly processed and approved the
distribution and all necessary accounting and Account valuation
activities have been performed.

                              ARTICLE VIII
                        BENEFICIARY DESIGNATION
                        -----------------------

     8.1    Beneficiary Designation.  Each Participant shall have the
            -----------------------
right, at any time, to designate one or more persons or an entity as
Beneficiary (both primary as well as secondary) to whom benefits under
the Plan shall be paid in the event of the Participant's death prior
to complete distribution of the Participant's Account.  Each
Beneficiary designation shall be in a written form prescribed by the
Administrator and shall be effective only when filed with the Plan
Administrator during the Participant's lifetime.  Participants may,
subject to Administrator consent, designate several Beneficiaries for
each Compensation Deferral Subaccount and associated investment
return, income, gain or loss credited thereto.

     8.2    Changing Beneficiary.  Any Beneficiary designation may be
            --------------------
changed by filing a new designation with the Plan Administrator.  The
filing of a new designation shall cancel all designations previously
filed.

     8.3    Change in Marital Status.  If the Participant's marital
            ------------------------
status changes after the Participant has designated a Beneficiary, the
prior designation shall be void if the former spouse was named as
Beneficiary; however, the prior designation shall remain valid if a
nonspouse beneficiary was named.

    8.4     No Beneficiary Designation.  If any Participant fails to
            --------------------------
designate a Beneficiary in the manner provided above, or if the
designation is void, or if the Beneficiary designated by a deceased
Participant dies before the Participant, the Participant's Beneficiary
shall be the person in the first of the following classes in which
there is a survivor:

     (a)    the surviving spouse;

     (b)    the Participant's surviving children in equal shares; or

     (c)    the Participant's estate.

     A Beneficiary who is receiving benefits after a Participant's
death may designate a successor Beneficiary to receive any remaining
payments in the event of the Beneficiary's death before all payments
are made.  The provisions hereof relating to designation of a
Beneficiary by the Participant shall apply in like manner to the
designation of a successor Beneficiary by a Beneficiary.

     8.5    Unless the context does not allow, all references to
Participant in this Article VIII shall also refer to Inactive
Participant unless otherwise noted.

                              ARTICLE IX

Participant or Inactive Participant without the written consent of

appropriate.  The Plan may only be amended (or terminated as provided
in Section 9.2 below) by written resolution of the Committee.

     (a)    Partial Termination.  The Company may partially terminate
            -------------------
the Plan by not accepting any additional or ongoing deferral
commitments.  In the event of such a partial termination, the Plan
shall continue to operate on the same terms and conditions and, unless
the Company determines not to accept ongoing Compensation Deferral
commitments, shall be effective with regard to Compensation Deferral
commitments entered into prior to the effective date of such partial
termination.

     (b)    Complete Termination.  The Committee may completely
            --------------------
terminate the Plan by resolution.  In the event of complete
termination, the Plan shall cease to operate, and the Company shall
pay out to each Participant or Inactive Participant his remaining
Accounts in one lump sum payment as soon as practicable.

involving solely his rights under the Plan.

     (c)    The Committee may act at a meeting, or by writing without

action or matter involving solely his rights under the Plan.  In the
absence of a specific designation by the Committee of a Plan
Administrator, the Committee shall be the Plan Administrator.

any other dispute with respect to the Plan, he may file a claim with
the Plan Administrator.  Such a claim shall be in writing and state
the nature of the claim, the facts supporting the claim, the amount
claimed, and the address of the claimant.  The Plan Administrator
shall review the claim and, unless special circumstances require an

written notice by mail to the claimant of his decision with respect to
the claim.  If special circumstances require an extension of time, the
claimant shall be so advised in writing within the initial 60-day
period and in no event shall such an extension exceed 30 days.  The
notice of the decision of the Plan Administrator with respect to the
claim shall be written in a manner calculated to be understood by the
claimant and, if the claim is wholly or partially denied, set forth
the specific reasons for the denial, specific references to the
pertinent Plan provisions on which the denial is based, a description
of any additional material or information necessary for the claimant
to perfect the claim and an explanation of why such material or
information is necessary, and an explanation of the claim review
procedure under the Plan.  If all or any portion of the claimant's
claim has been denied by the Plan Administrator, the claimant may
request a review by the Committee of the denial by filing with the
Committee, within 60 days after notice of the denial has been received
by the claimant, a written request for such review.  The claimant may
have reasonable access to pertinent documents and submit comments in
writing to the Committee within the same 60-day period.  If a request
is so filed, review of the denial shall be made by the Committee
within, unless special circumstances require an extension of time, 60
days after receipt of such request, and the claimant shall be given
written notice of the Committee's final decision.  If special
circumstances require an extension of time, the claimant shall be so
advised in writing within the initial 60-day period and in no event
shall such an extension exceed 60 days without agreement of claimant.

reasons for the decision and specific references to the pertinent Plan
provisions on which the decision is based.  The Committee's decision
shall be final and binding on all parties.  The claim and appeal
process outlined above shall be the exclusive process for resolution

claimant fails to use and exhaust such process as described, the
claimant, Inactive Participant or Participant shall be barred from
further contesting the matter and actions of the Plan Administrator.

such benefits.  Such trust or trusts may be irrevocable, but he assets
thereof ultimately shall be subject to the claims of the Company's
creditors.  To the extent any benefits provided under the Plan are
actually paid from any such Trust, the Company and Plan shall have no
further obligation with respect thereto, but to the extent not so

by, the Company.

            ---------------------

     10.10  Payment to Guardian.  If a distribution is payable to a
            -------------------
minor or a person declared incompetent or to a person incapable of

the care and custody of such minor, incompetent or person.  The Plan
