                     ABBOTT LABORATORIES STOCK RETIREMENT PROGRAM

PREAMBLE

     1.1  PURPOSE.  This document amends and restates the provisions of the
Abbott Laboratories Stock Retirement Plan (the "Program"), effective as of
January 1, 1996.  Effective January 1, 1996, the Program shall be known as the
Abbott Laboratories Stock Retirement Program.  The Program consists of this
Preamble and two parts, Part A titled "Abbott Laboratories Stock Retirement
Plan" and Part B titled "Abbott Laboratories Stock Retirement Plan (Puerto
Rico)".  Part A shall be funded by a trust known as "Abbott Laboratories Stock
Retirement Trust" and Part B shall be funded by a separate trust known as
"Abbott Laboratories Stock Retirement Trust (Puerto Rico)".  Part A and its
related trust are intended to qualify as a profit sharing plan and trust under
Sections 401(a) and 501(a) of the United States Internal Revenue Code of 1986,
as amended (the "U.S. Code"), the cash or deferred arrangement forming a part of
Part A is intended to qualify under Section 401(k) of the U.S. Code, and the
provisions of Part A and its related trust shall be construed and applied
accordingly.  Part B, the cash or deferred arrangement forming a part of Part B,
and its related trust are intended to qualify as a profit sharing plan and trust
under Sections 1165(a) and (e) of the Puerto Rico Internal Revenue Code of 1994
(the "PR Code"), and the provisions of Part B and its related trust shall be
construed and applied accordingly.

     1.2  HISTORY OF THE PROGRAM.  The Program was originally established by
Abbott Laboratories (the "Corporation"), effective July 9, 1951, to facilitate
the retirement of eligible participating employees by providing benefits which
reenforce those available to such employees under the Abbott Laboratories
Annuity Retirement Plan and other Abbott Laboratories retirement benefits.

     The Program provides an arrangement by which employees may invest in stock
of the Corporation ("Company Stock") by contributing to the applicable trust
under Part A or Part B and by which the Corporation and its affiliates will
encourage such investment by also making contributions to such trusts. 
Contributions received by the trusts from Participants and Employers have been
applied by the trustees thereof to acquire, and hold, shares of Company stock
for the benefit of Participants in the Program.

     Part A as in effect on January 1, 1996 applies to "Eligible Employees" of
the Corporation and of certain of its Subsidiaries and Divisions, as provided
for in Part A.  Part B as in effect on January 1, 1996 applies to "Eligible
Employees" of certain Subsidiaries of the Corporation as provided for in Part B.

     1.3  RIGHTS UNDER PRIOR PLAN.  Except as otherwise specifically provided,
the benefits provided under the Program for any Participant who retired or whose
employment with the Employers otherwise terminated prior to January 1, 1996
shall be governed in all respects by the terms of the Program as in effect on
the date of his or her retirement or other termination of employment.
     
     1.4  EMPLOYER CONTRIBUTIONS.  For each Plan Year, beginning with the 
Plan Year ending December 31, 1997, the Employers participating under Part A 
or Part B shall make Employer contributions to the trust for Part A or Part 
B, as applicable, for the benefit of each Participant who is an Eligible 
Employee under such part at any time during the Plan Year and on whose behalf 
Basic Contributions have been made at any time during the Plan Year.  The 
aggregate amount of Employer Contributions made by the Employers to the 
Program for the Plan Year shall be determined from time to time by the Board 
of Directors of the


                                     -2-

Corporation; provided, however, that the amount of such Employer Contributions
shall not exceed 7.5% of the total dividends declared by the Corporation in that
Plan Year on issued and outstanding shares of Company Stock (exclusive of
dividends declared in that Plan Year on shares of the Company Stock issued for
purposes of an acquisition or merger where employees of the acquired or merged
company are not included in the Program) regardless of whether the dividends are
payable in that Plan Year. 

For each Plan Year, the Corporation shall allocate the aggregate Employer
Contributions to the Program between Part A and Part B in the proportion and
amounts necessary for the Point Value under Part A (as defined in Section 15.37
of Part A) to have the same dollar value as the Point Value under Part B (as
defined in Section 14.36 of Part B).    

     1.5  DEFINITIONS.  Except where otherwise noted, words and phrases used in
this Preamble shall have the same meaning as the meanings assigned such words
and phrases under Part A and Part B.

     1.6  AMENDMENT AND TERMINATION.  The Corporation reserves the power to
amend this Preamble from time to time, to any extent and in any manner that it
may deem advisable.  All major amendments and all decisions or amendments which
are reasonably expected to have the effect of suspending or terminating Employer
contributions or suspending or terminating payment of benefits to Participants
or Beneficiaries, or terminating the Program shall be made by the Board of
Directors of the Corporation.  All other amendments shall be made by the Board
of Review.  For purposes of the foregoing, the term "major amendment" shall have
the same meaning as the meaning given that phrase in Part A.  Part A and Part B
may be amended and terminated as provided therein.  This Preamble shall
terminate upon termination of both Part A and Part B.

                              effective August 1, 1997)
                                           
                                           


                                           
                             ARTICLE 1.  INTRODUCTION
                                           
     1.1. PURPOSE.  This document amends and restates the provisions of the
Abbott Laboratories Stock Retirement Plan (the "Plan"), effective as of January
1, 1996.  The Plan and its related Trust are intended to qualify as a
profit-sharing plan and trust under Code sections 401(a) and 501(a), the cash or
deferred arrangement forming part of the Plan is intended to qualify under Code
section 401(k), and the provisions of the Plan and Trust shall be construed and
applied accordingly.

     1.2. HISTORY OF THE PRIOR PLAN.  The Plan was originally established by
Abbott Laboratories (the "Corporation"), effective July 9, 1951, to facilitate
the retirement of eligible participating employees by providing benefits which
reinforce those available to such employees under the Abbott Laboratories
Annuity Retirement Plan and other Abbott Laboratories retirement benefits. 

     The Plan provides an arrangement by which employees may invest in stock of
the Corporation ("Company Stock") by contributing to the Abbott Laboratories
Stock Retirement Trust (the "Trust") and by which the Corporation and its
affiliates will encourage such investment by also making contributions to the
Trust.  Contributions received by the Trust from the Participants and from the
Employers have been applied by the Trustee to acquire, and hold under the Trust,
shares of Company Stock for the benefit of the Participants in the Plan, to the
end that upon retirement or prior termination of employment, the Participants
may receive a distribution of Company Stock and/or an annuity.

     On February 24, 1964, the Corporation was substituted as the employer under
the M & R Retirement Investment Trust and effective as of April 1, 1969, the M &
R Retirement Investment Trust was consolidated with the Plan and Abbott
Laboratories Stock Retirement Trust.  Special provisions relating to employees
and other persons covered under the M & R Retirement Investment Trust when it
was consolidated with the Plan and the Trust are set forth in Supplement A to
the Prior Plan.  Supplement A modified the Prior Plan and the Trust to the
extent it was inconsistent with the Prior Plan and Trust.
     
     The Plan as in effect on January 1, 1996 applies to Eligible Employees of
the Corporation and of all Subsidiaries and Divisions that participated in the
Plan as of December 31, 1995.  The Plan will also apply to Eligible Employees of
any Subsidiary or Division that is designated by the Board of Review to
participate in the Plan in accordance with Section 2.6, from and after the
effective date of such designation.

     1.3. RIGHTS UNDER PRIOR PLAN.  Except as otherwise specifically provided,
the benefits provided under the Plan for any Participant who retired or whose
employment with the Employers otherwise terminated prior to January 1, 1996 will
be governed in all respects by the terms of the Prior Plan as in effect on the
date of his or her retirement or other termination of employment.

                              ARTICLE 2.  PARTICIPATION
                                           
     2.1. DATE OF PARTICIPATION.  Each individual who was a Participant on
December 31, 1995 and is an Eligible Employee on January 1, 1996 shall continue
to be a Participant in the Plan.  Each other Employee shall become a Participant
(a) for purposes of making Supplemental Contributions, on any Entry Date
following his or her date of hire after he or she has entered into a
Contribution Agreement under Section 3.4, and (b) for purposes of 



Basic Contributions and Employer Contributions on an Entry Date following the 
day he or she completes two Years of Credited Service and completes the 
applicable forms under Sections 2.2 and 3.4, provided in each case that he or 
she is an Eligible Employee on such Entry Date.

     2.2. ENROLLMENT OF PARTICIPANTS.  An Eligible Employee shall become a
Participant by signing an application form furnished by the Administrator within
30 days after he or she receives the application, or by such other means as the
Administrator establishes for enrollment.  Such application shall authorize the
Participant's Employer to deduct from his or her Compensation (or reduce his or
her Compensation by) the contributions required under Section 3.2 or 3.3,
whichever is applicable.

     2.3. REEMPLOYMENT OF PARTICIPANT.  If an Employee's employment with the
Corporation, an Affiliated Corporation or a Subsidiary should terminate and such
Employee is subsequently reemployed by the Corporation, an Affiliated
Corporation or a Subsidiary, the following shall apply:

          (a)  If the reemployment occurs before the Employee has a Break Year,
     the Period of Credited Service to which he or she was entitled at the time
     of termination shall be reinstated, the period of his or her absence (but
     not to exceed 12 months) shall be included in his or her Period of Credited
     Service, and he or she will be reinstated as a Participant on his or her
     date of reemployment, if the Participant is an Eligible Employee on that
     date.

          (b)  If an Employee is reemployed after a Break Year, and at the 
     time of termination he or she was not a Participant in the Plan, then:

              (i)  If the Employee's Years of Credited Service to which  he 
          or she was entitled at the time of termination exceeds his or her 
          number of consecutive Break Years, the Period of Credited Service 
          to which he or she was entitled at the time of termination shall be 
          reinstated and he or she will be reinstated as a Participant on his 
          or her date of reemployment if he or she is then an Eligible 
          Employee.

              (ii)  If the Employee's number of consecutive Break Years 
          equals or exceeds the Period of Credited Service to which he or she 
          was entitled at the time of termination, the Employee shall be 
          considered as a new Employee for all purposes of the Plan and any 
          Period of Credited Service to which he or she was entitled prior to 
          the date of termination shall be disregarded.

          (c)  If an Employee is reemployed after a Break Year, and at the time
     of termination he or she was a Participant in the Plan, the Period of
     Credited Service to which he or she was entitled at the time of termination
     shall be reinstated.

          (d)  If a Participant is transferred or is given a leave of absence
     for a temporary or indefinite period for the purpose of becoming an
     Employee of a Subsidiary or an Affiliated Corporation which is not an
     Employer hereunder, and such Participant is not treated as an Eligible
     Employee under Section 15.23(b), he or she will continue as a Participant
     until his or her retirement date or earlier termination of service with the
     Corporation, all Affiliated Corporations and all Subsidiaries, except that
     during 

                                     2


     such period the Employee may not make any contributions and will not
     be credited with any Employer contributions except for a pro rata share of
     his or her Employer's contributions for the year in which the transfer is
     made or the leave began, as the case may be, based upon his or her own
     contributions and service up to the date of such transfer or the date such
     leave began, as the case may be.  If a Participant's employment with the
     Corporation, all Affiliated Corporations and all Subsidiaries is terminated
     by reason of his or her death, retirement or otherwise while he or she is
     employed by the Corporation, any Affiliated Corporation or any Subsidiary
     which is not an Employer hereunder, the Participant will be considered to
     have terminated his or her employment with the Employers at the same time
     and for the same reason.

          (e)  In the case of maternity or paternity absence (as defined below)
     which commences on or after January 1, 1985, an Employee shall be deemed to
     be employed by the Corporation, an Affiliated Corporation, or any
     Subsidiary (solely for purposes of determining whether the Employee has
     incurred a Break Year) during the calendar year following the calendar year
     in which his or her employment terminated.  A "maternity or paternity
     absence" means an Employee's absence from work because of the pregnancy of
     the Employee or birth of a child of the Employee, the placement of a child
     with the Employee in connection with the adoption of such child  by the
     Employee, or for purposes of caring for the child immediately following
     such birth or placement.  The Administrator may require the Employee to
     furnish such information as the Administrator considers necessary to
     establish that the employee's absence was for one of the reasons specified
     above.

     2.4. DURATION OF PARTICIPATION.  An individual who has become a Participant
under the Plan will remain a Participant for as long as an Account is maintained
under the Plan for his or her benefit, or until his or her death, if earlier. 
Notwithstanding the preceding sentence and unless otherwise expressly provided
for under the Plan, no contributions under the Plan shall be made on behalf of
any Participant, unless the Participant is an Eligible Employee at the time for
which the contribution or allocation is made.

     2.5. PARTICIPANT RESTRICTED DUE TO CONFLICT OF INTEREST. If a conflict of
interest as defined in subsection (d) should arise with respect to any
Participant:

     (a)  Such Participant shall continue as a Participant until his or her 
    retirement date or earlier termination of service with the Employer, an 
    Affiliated Corporation or a Subsidiary, except that during the period of 
    such conflict of interest such Participant shall make no Basic After-Tax 
    Contributions, such Participant's Employer shall make no Basic Pre-Tax 
    Contributions on his or her behalf, and such Participant shall be 
    credited with no Employer Contributions except for a pro rata share of 
    his or her Employer's Employer Contributions for the year in which such 
    conflict arises, based on his or her Basic Contributions and service to 
    the date such conflict arises.

     (b)  Such Participant must, within 30 days after notice from the 
    Administrator, elect to have 100% of the value of the shares of Company 
    Stock credited to his or her Accounts transferred to the SRP Stable Value 
    Fund or one of the other investment options available under the Plan 
    (other than Company Stock).  If the Participant fails to make such 
    election, such shares shall be sold and the sale proceeds shall be 

                                    3


    transferred to the default Investment Fund selected under Section 5.8.  Any
    Basic After-Tax Contributions, Basic Pre-Tax Contributions and pro-rata 
    Employer Contributions, any Supplemental After-Tax Contributions and 
    Supplemental Pre-Tax Contributions designated by the Participant under 
    Section 5.1 to be invested in shares of Company Stock, and any dividends 
    on shares of Company Stock held in the Participant's Accounts, made for 
    or paid during the calendar year in which such conflict of interest 
    arises, shall likewise be transferred to the investment option the 
    Participant selects under the first sentence of this subsection (b) or to 
    the default Investment Fund referred to in the second sentence.  These 
    transfers shall not be subject to any of the investment restrictions or 
    transition rules described in Sections 5.4, 5.5 or 5.6.

     (c)  Such Participant may elect to make Supplemental After-Tax 
    Contributions and Supplemental Pre-Tax Contributions during the period of 
    such conflict of interest, notwithstanding the suspension of Basic 
    After-Tax Contributions and Basic Pre-Tax Contributions under subsection 
    (a), provided that no such contributions may be invested in shares of 
    Company Stock.

     (d)  A "conflict of interest" means a business, professional, family or 
    other relationship involving the Participant which, as a result of 
    statute, ordinance, regulation or generally recognized professional 
    standard or rule requires divestiture by the Participant of shares of 
    Company Stock.  The existence or nonexistence of a conflict of interest 
    for purposes of this Section 2.5 shall be determined by the 
    Administrator, which determination shall be final and binding on all 
    persons.  Any determination made under this subsection (d) shall have no 
    effect on the application of any human resources or corporate policies of 
    any Employer regarding conflict of interest.

     2.6. PARTICIPATION BY ADDITIONAL PARTICIPATING EMPLOYERS.  The Board of
Review may extend the Plan to any nonparticipating Division by filing with the
Trustee and the Co-Trustees a certified copy of an appropriate resolution by the
Board of Review to that effect.  Any Subsidiary or Affiliated Corporation may
adopt the Plan and become a participating Employer hereunder by:
     
     (a)  filing with the Board of Review, the Trustee and Co-Trustees a 
    written instrument to that effect, and
          
    (b)  filing with the Trustee and the Co-Trustees a certified copy of a 
    resolution of the Board of Review consenting to such action.  

At the time the Plan is extended to any Division of the Corporation or is
adopted by any Subsidiary or Affiliated Corporation or any time thereafter, the
Board of Review may modify the Plan or any of its terms as applied to said
Division, Subsidiary, or Affiliated Corporation and its employees.  The Board of
Review may include in the Plan any employee of any prior separate business
entity, part or all of which was acquired by or becomes a part of any Employer. 
To the extent and on the terms so provided by the Board of Review at the time of
acquisition, or at any subsequent date or in any Supplement to the Plan, the
last continuous period of employment of any employee with such prior separate
business entity, part or all of which is or was acquired by, or becomes a part
of any Employer, will be considered a Period of Credited Service.


                                    4


     2.7. SECURITIES LAW RESTRICTIONS.
  
         (a)  The Administrator may, from time to time, impose such
     restrictions on participation in the Plan, as the Administrator deems
     advisable, to facilitate compliance with federal and state securities laws,
     to secure exemption under any rule of the Securities and Exchange
     Commission, or to comply with the Corporation's corporate policy with
     respect to "blackout periods" related to Company Stock.  Such restrictions
     shall apply to all Participants or to such individual Participants as the
     Administrator shall determine in his or her sole discretion and may include
     but shall not be limited to (i) moratoriums on purchases, sales,
     withdrawals or distributions of Company Stock; (ii) moratoriums on loans
     and transfers into and out of Company Stock; and (iii) suspensions of Basic
     Contributions and Supplemental Contributions allocated to Company Stock. 

         (b)  Any Participant for whom Basic Contributions are suspended under
     Section 2.7(a) may elect to make or continue making Supplemental
     Contributions, provided that no such contributions may be invested in
     shares of Company Stock.

                              ARTICLE  3. CONTRIBUTIONS
                                           
     3.1. PARTICIPANT CONTRIBUTIONS.  Except as provided in Sections 2.5 and
2.7, each Participant who has satisfied the eligibility requirements of Section
2.1(b) may have Basic Contributions made to the Plan on his or her behalf as
described in Section 3.2.  Each Participant who has satisfied the eligibility
requirements of Section 2.1(a) may elect to have Supplemental Contributions made
to the Plan on his or her behalf as described in Section 3.3 at any time after
his or her date of hire; provided, however, that if the Participant is eligible
to make Basic Contributions, he or she may make Supplemental Contributions only
if Basic Contributions are concurrently being made.

     3.2. BASIC CONTRIBUTIONS.  Except as provided in Section 2.5, each
Participant who is an Eligible Employee may enter into a Contribution Agreement
with the Employer under which the Participant's Compensation for each pay period
shall be reduced by 2%, and the Employer will contribute to the Trust an equal
amount as a Basic Pre-Tax Contribution, or as a Basic After-Tax Contribution, as
the Participant elects.  For purposes of this Section 3.2, Compensation shall be
limited to that portion of his or her Compensation as is determined from time to
time by the Board of Directors or the Board of Review.  Each Participant who
makes such contributions shall be eligible to share in the Employer
Contributions under Section 3.5.

     3.3. SUPPLEMENTAL CONTRIBUTIONS.  If a Participant has made the Basic
Contributions required under Section 3.2 (or is not yet eligible to make such
contributions because he or she has not completed two Years of Credited
Service), he or she may make Supplemental Contributions in an amount equal to an
additional 1% to 10% of his or her Compensation as Supplemental Pre-Tax
Contributions and an additional 1% to 10% of his or her Compensation as
Supplemental After-Tax Contributions; provided that the aggregate Supplemental
Contributions shall not exceed 16% of the Participant's Compensation, and all
Supplemental Contributions shall be multiples of 1% of the Participant's
Compensation.  The Participant shall elect in the Contribution Agreement
described in Section 3.4 to make such contributions  as Supplemental Pre-Tax
Contributions, as Supplemental After-Tax 


                                    5


Contributions, or both, as applicable. No Employer Contributions under 
Section 3.5 shall be made with respect to such Supplemental Contributions.

     3.4. CONTRIBUTION AGREEMENTS.  Each Contribution Agreement shall be on a 
form prescribed or approved by the Administrator or in such manner as the 
Administrator finds acceptable, and may be entered into, changed or revoked 
by the Participant, with such prior notice as the Administrator may 
prescribe, as of the first day of any pay period with respect to Compensation 
payable thereafter.  A Contribution Agreement shall be effective with respect 
to Compensation payable to a Participant after the date determined by the 
Administrator, but not earlier than the date the Agreement is entered into.  
The Administrator may reject, amend or revoke the Contribution Agreement of 
any Participant if the Administrator determines that the rejection, amendment 
or revocation is necessary to ensure that the limitations referred to in 
Section 3.8 and Article 11 are not exceeded.

     3.5. EMPLOYER CONTRIBUTIONS. For each Plan Year beginning in or after 1996,
the Employers shall make Employer Contributions to the Trust for the benefit of
each Participant who is an Eligible Employee at any time during the Plan Year
and on whose behalf Basic Contributions have been made at any time during the
Plan Year.  The amount of Employer Contributions made by the Employers for a
Plan Year shall be that amount allocated to the Plan under Section 1.4 of the
Preamble to the Abbott Laboratories Stock Retirement Program for such Plan Year.

     The Employers may contribute from time to time to the Unallocated Account a
portion of the estimated Employer Contributions for the Plan Year.  The Trustee
shall invest such funds in Company Stock periodically in accordance with stock
trading procedures established by the Co-Trustees and agreed to by the Trustee. 
All dividends paid during the year on the Company Stock thus purchased and held
in the Unallocated Account and other income received on Employer Contributions
held in the Unallocated Account pending investment in Company Stock shall be
used to purchase additional Company Stock to the extent such funds are not used
to pay Plan expenses.

     After the amount of Employer Contributions for the Plan Year has been
determined, the Employers shall pay the remaining Employer Contributions to the
Trust within 90 days after the end of the Plan Year.  The Company Stock
purchased with such additional Employer Contributions and all shares of Company
Stock then held in the Unallocated Account shall be allocated among the accounts
of the eligible Participants as of the last day of the Plan Year, based on the
value of the Participant's earnings points and service points determined as
follows:

          (a)  One earnings point will be allocated to each eligible Participant
     for each $2 of Basic Contributions made on his or her behalf during the
     Plan Year;

          (b)  Five service points will be allocated to each eligible
     Participant for each full Year of Credited Service he or she has earned as
     of the end of the Plan Year, not to exceed 175 service points;

          (c)  A Participant who dies, retires under the Abbott Laboratories
     Annuity Retirement Plan, or terminates employment with an Employer on
     account of total disability for which benefits are payable under the Abbott
     Laboratories Extended Disability Plan, at any time during the Plan Year,
     will be considered as having 


                                    6




     continued to be employed until December 31 of that Year and will thus 
     earn a Year of Credited Service for purposes of subsection (b);

          (d)  A Participant who separates from service with the Corporation,
     all Affiliated Corporations and all Subsidiaries for any reason other than
     death, disability or retirement, at any time during the Plan Year, will be
     allocated a pro rata portion of the service points the Participant would
     have received had the Participant continued to be employed until December
     31 of that Year, prorated based on the months during the Plan Year prior to
     the Participant's separation from service, and will thus earn a partial
     Year of Credited Service for purposes of subsection (b);

          (e)  A Participant who is transferred or given a leave of absence in
     circumstances described in Section 2.3(d) above, at any time during the
     Plan Year, will be allocated a pro rata portion of the service points the
     Participant would have received had the Participant continued until
     December 31 of that year, prorated based on the Participant's service up to
     the date of such transfer or the date such leave began, as the case may be,
     and will thus earn a partial Year of Credited Service for purposes of
     subsection (b);

          (f)  If  (i) a Participant retires under the Abbott Laboratories
     Annuity Retirement Plan and elects to receive the distribution of his or
     her Accounts during the same Plan Year, (ii) a Participant dies during the
     Plan Year and the Beneficiary elects to take a distribution of the
     Participant's Accounts during the same Plan Year; or (iii) a Participant
     separates from service during the Plan Year for reasons other than
     retirement or death and does not elect to defer his distribution to a later
     Plan Year, the Employer Contribution due in each case for the Plan Year
     shall be calculated using the Point Value determined for the prior Plan
     Year and allocated to the applicable Participant's Employer Contribution
     Account.  If a Participant or Beneficiary who becomes eligible for a
     distribution during the Plan Year does not take a distribution during the
     same Plan Year as described in the prior sentence, the Employer
     Contribution which would be allocable to his or her Accounts shall be
     determined and allocated as of the end of the Plan Year under Subsection
     3.5(g) below, as if the Participant were actively employed as of the last
     day of the Plan Year, but shall be calculated as described in (a)-(e) above
     based on the service recognized therein.

          (g)  The amount of the Company Stock which will be allocated as of the
     end of the Plan Year to the Employer Contribution Account of each eligible
     Participant for such Plan Year shall be determined by multiplying the
     aggregate cost (after adding earnings and deducting expenses as herein
     permitted) of the Company Stock held in the Unallocated Account at the end
     of the Plan Year by a fraction, the numerator of which is the sum of the
     Participant's earnings points and service points as of the end of the Plan
     Year and the denominator of which is the aggregate of all earnings points
     and all service points for all eligible Participants as of the end of such
     Plan Year (less the points attributable to Participants to whom or on whose
     behalf distributions are made during the Plan Year).  Once the portion of
     the aggregate cost which is attributable to each eligible Participant is
     determined, the applicable number of shares represented by such cost shall
     be allocated to the Participant's Employer Contribution Account. 


                                    7


     3.6. QUALIFIED NONELECTIVE EMPLOYER CONTRIBUTIONS.  At the direction of 
the Corporation, an Employer may make Qualified Nonelective Employer 
Contributions to the Trust for a Plan Year either (a) on behalf of all 
Participants for whom Pre-Tax Contributions are made for the Plan Year, or 
(b) on behalf of only those Participants for whom Pre-Tax Contributions for 
the Plan Year are made and who are not Highly Compensated Employees for the 
Plan Year, as the Board of Review shall determine.  Such Qualified 
Nonelective Employer Contributions shall be made only if, when they are 
combined with all employer contributions to all plans which form a part of 
the Abbott Laboratories Stock Retirement Program, the aggregate employer 
contributions of the Employers for the Plan Year to all such plans do not 
exceed 7.5 percent of the declared dividends of the Corporation for the Plan 
Year.  Except as otherwise expressly provided for, any Qualified Nonelective 
Employer Contribution shall be treated as a Pre-Tax Contribution for all 
purposes under the Plan. Qualified Nonelective Employer Contributions may be 
made pursuant to this Section 3.6, (i) with respect only to Participants who 
are employed by any Subsidiary which is not an Affiliated Corporation, (ii) 
with respect only to Participants who are employed by Employers which are 
Affiliated Corporations,  or (iii) with respect to Participants described in 
both (i) and (ii).

     3.7. TIME FOR MAKING AND CREDITING OF CONTRIBUTIONS.  Basic and 
Supplemental Pre-Tax and After-Tax Contributions will be withheld from the 
Participants' Compensation through payroll deductions and will be paid in 
cash to the Trust as soon as such contributions can reasonably be segregated 
from the general assets of the Employers, but in any event within 90 days 
after the date on which the Compensation to which such contributions relate 
is paid.  Such contributions will be credited to the Participants' respective 
Pre-Tax Contribution and After-Tax Contribution Accounts as of the earlier of 
(a) the date such contributions are received by the Trust and (b) the last 
day of the Plan Year in which the Compensation is paid.  In addition and 
subject to the limits provided in Section 3.3, a Participant may make 
Supplemental After-Tax Contributions by delivering to the Trustee, a 
certified check in the amount of such contribution and the contribution shall 
be credited to the Participant's Supplemental After-Tax Contribution Account 
as of the date it is received by the Trustee. Any Employer Contributions or 
Qualified Nonelective Employer Contributions for a Plan Year will be 
contributed to the Trust at such time as the Corporation determines, but no 
later than the time prescribed by law (including extensions) for filing the 
Corporation's federal income tax return for its taxable year in or with which 
the Plan Year ends.  Such contributions will be credited to the Employer 
Contribution Accounts or Pre-Tax Contribution Accounts, respectively, of 
Participants on whose behalf they are made at such time as the Corporation 
determines, but no later than the last day of such Plan Year.

     3.8. CERTAIN LIMITS APPLY.  All contributions to this Plan are subject 
to the applicable limits set forth under Code sections 401(k), 401(m), 
402(g), 404, and 415, as further described in Article 11.

     3.9. RETURN OF CONTRIBUTIONS.  No property of the Trust or contributions 
made by the Employers pursuant to the terms of the Plan shall revert to the 
Employers or be used for any purpose other than providing benefits to 
Eligible Employees or their Beneficiaries and defraying the expenses of the 
Plan and the Trust, except as follows: 

          (a)  Upon request of the Corporation, contributions made to the Plan
     before the issuance of a favorable determination letter by the Internal
     Revenue Service with 


                                    8



     respect to the initial qualification of the Plan under Section 401(a) of 
     the Code may be returned to the contributing Employer, with all 
     attributable earnings, within one year after the Internal Revenue Service 
     refuses in writing to issue such a letter.

          (b)  Any amount contributed under the Plan by an Employer by a mistake
     of fact as determined by the Employer may be returned to such Employer upon
     its request, within one year after its payment to the Trust.

          (c)  Any amount contributed under the Plan by an Employer on the
     condition of its deductibility under Section 404 of the Code may be
     returned to such Employer upon its request, within one year after the
     Internal Revenue Service disallows the deduction in writing.

          (d)  Earnings attributable to contributions returnable under paragraph
     (b) or (c) shall not be returned to the Employer, and any losses
     attributable to those contributions shall reduce the amount returned.

In no event shall the return of a contribution hereunder cause any Participant's
Accounts to be reduced to less than they would have been had the mistaken or
nondeductible amount not been contributed.  No return of a contribution
hereunder shall be made more than one year after the mistaken payment of the
contribution, or disallowance of the deduction, as the case may be.

     3.10.     SPECIAL LIMITS FOR CORPORATE OFFICERS.  Notwithstanding any other
provision of the Plan, the Administrator may, from time to time, impose
additional limits on the percentages of Compensation which may be contributed to
the Plan by, or on behalf of, Corporate Officers, provided that such additional
limits are lower than the limits applicable to other Participants.  The amount
and terms of such limits shall be determined by the Administrator in its sole
discretion, need not be the same for all Corporate Officers and may be changed
or repealed by the Administrator at any time.  For purposes of this Section
3.10, the term "Corporate Officer" shall mean an individual elected an officer
of the Corporation by its Board of Directors but shall not include assistant
officers. 

                          ARTICLE 4.  PARTICIPANT ACCOUNTS 
                                           
     4.1. ACCOUNTS.  The Administrator will establish and maintain (or cause the
Trustee to establish and maintain) for each Participant a Basic After-Tax
Contribution Account, a Basic Pre-Tax Contribution Account, a Supplemental
After-Tax Contribution Account, a Supplemental Pre-Tax Contribution Account, an
Employer Contribution Account, a Rollover Contribution Account (if applicable),
a Transfer Contribution Account (if applicable) and such other accounts or
sub-accounts as the Administrator in its discretion deems appropriate.  All such
Accounts shall be referred to collectively as the "Accounts".

     4.2. ADJUSTMENT OF ACCOUNTS.  Except as provided in the following sentence,
as of each Valuation Date, the Administrator or Trustee, as the case may be,
shall adjust the balances of each Account maintained under the Plan on a uniform
and consistent basis to reflect the contributions, distributions, income,
expense, and changes in the fair market value of the assets attributable to such
Account since the prior Valuation Date, in such reasonable manner as the
Administrator or Trustee, as the case may be, shall determine.  Employer
Contributions made to the Unallocated Account, Company Stock acquired under


                                    9




Section 3.5 with such Employer Contributions, and dividends paid on such Company
Stock will not be valued as of each Valuation Date, but will be allocated to the
Participants' Accounts only as of the end of the Plan Year in accordance with
Section 3.5 and thereafter such amounts will be valued in accordance with the
first sentence of this Section 4.2.  Notwithstanding any other provision of the
Plan, to the extent that Participants' Accounts are invested in mutual funds or
other assets for which daily pricing is available ("Daily Pricing Media"), all
amounts contributed to the Trust will be invested at the time of their actual
receipt by the Daily Pricing Media, and the balance of each Account shall
reflect the results of such daily pricing from the time of actual receipt until
the time of distribution.  Investment elections and changes made pursuant to
Section 5.7 shall be effective upon receipt by the Daily Pricing Media. 
References elsewhere in the Plan to the investment of contributions "as of" a
date other than that described in this Section 4.2 shall apply only to the
extent, if any, that assets of the Trust are not invested in Daily Pricing
Media.

                          ARTICLE 5.  INVESTMENT OF ACCOUNTS
                                           
     5.1. COMPANY STOCK.  All Basic Contributions and Employer Contributions 
shall be invested in shares of Company Stock.  A Participant may also direct 
that some or all of his or her Supplemental Contributions, Rollover 
Contributions (if applicable) or Transfer Contributions (if applicable) be 
invested in shares of Company Stock.  Company Stock shall be purchased and 
sold by the Trustee on the open market or from the Corporation in accordance 
with stock trading procedures established by the Co-Trustees and agreed to by 
the Trustee.

     5.2. SRP STABLE VALUE FUND.  All funds invested in the Fixed Income Option

shall be invested in the SRP Stable Value Fund on and after January 1, 1996,
unless and until such funds are transferred to another Investment Fund described
in Section 5.3.  A Participant may direct that some or all of his or her
Supplemental Pre-Tax Contribution Account or Supplemental After-Tax Contribution
Account be transferred to and invested in the SRP Stable Value Fund, subject to
the transition rules described in Section 5.4.  In addition, a Participant may
direct that some or all of his or her Supplemental Contributions, Rollover
Contributions, or Transfer Contributions made on or after January 1, 1996 be
invested in the SRP Stable Value Fund.

     5.3. OTHER INVESTMENT FUNDS.  The Co-Trustees may, from time to time,
direct the Trustee to establish one or more Investment Funds, which may include
registered investment companies (including those for which the Trustee or an
affiliate is the investment advisor, principal underwriter or distributor),
group trusts for the collective investment of pension and profit sharing plans
which are qualified under section 401(a) of the Code, and other pooled
Investment Funds.  A Participant may invest some or all of his or her
Supplemental Contributions, Rollover Contributions or Transfer Contributions
made on or after January 1, 1996 in one or more of the Investment Funds
available under the Plan in such increments and in such manner as the
Co-Trustees and the Trustee establish in investment procedures.  To the extent
permitted by Sections 5.4, 5.5 and 5.6, a Participant may instruct the Trustee
that  amounts held in his or her Accounts that are invested in Company Stock or
in the SRP Stable Value Fund be transferred to and invested in one or more of
the Investment Funds established under this Section 5.3.  Any amounts held in a
Participant's Accounts that are not otherwise restricted as to investment under
Section 5.1, 5.2, 5.4, 5.5 or 5.6 may be invested or reinvested in Company Stock
or any of the 


                                    10



Investment Funds then available under the Plan in accordance with
the procedures established under Section 5.7.

31, 1995 (the "Transition Amount") and which will be held in the SRP Stable
Value Fund as of January 1, 1996 will be considered restricted as to investment,
subject to the transition rules described in this Section 5.5.  A portion of the
Transition Amount shall become unrestricted (the "unrestricted amount") and, at
any time after April 3, 1996 (or such subsequent date as the Administrator
determines in his or her sole discretion), may be reinvested in one or more of
the other Investment Funds described in Section 5.3 as follows:
     
          (a)  Effective April 3, 1996 (or such subsequent date as the

     Plan.

     The restrictions and transition rules described in this Section 5.5 shall
apply to all Participants.

     5.6. PRE-RETIREMENT FEATURE FOR REINVESTMENT OF COMPANY STOCK.  Effective
April 3, 1996 (or such subsequent date as the Administrator determines in his or
her sole discretion) and notwithstanding the provisions of Section 5.4 above, a
Participant who has attained age 50 prior to January 1, 1996 or who will attain
age 50 during the 1996 calendar year, may direct the Trustee to sell all or a
portion of the Company Stock held in his or her Accounts as of January 1, 1996
(the "PRF Shares") and reinvest the proceeds in the SRP Stable Value Fund or in
any of the other Investment Funds described in Section 5.3.  The amount that
shall be available for reinvestment (the "unrestricted amount") shall be
determined in accordance with the following transition rules:

          (a)  APRIL 3, 1996.  Effective April 3, 1996 (or such subsequent date
     as the Administrator determines in his or her sole discretion), the

          (b)  JUNE 6, 1996.  Effective June 6, 1996 (or such earlier date as

     unrestricted amount shall be 50% of the PRF Shares (less the number of such
     Shares sold pursuant to subsection (a) above).

          (c)  AUGUST 8, 1996.  Effective August 8, 1996 (or such earlier date

          (d)  OCTOBER 3, 1996.  Effective October 3, 1996 (or such earlier date
     as the Administrator determines in his or her sole discretion), the
     unrestricted amount shall be 100% of the PRF Shares.

Effective January 1, 1997 and notwithstanding the provisions of Section 5.4
above, a Participant who attains age 50 may direct the Trustee to liquidate all
or a portion of the Company Stock held in his or her Accounts and reinvest the
proceeds in the SRP Stable Value Fund or in any of the other Investment Funds
described in Section 5.3.  Once a Participant becomes subject to the provisions
of this Section 5.6, the provisions of Section 5.4 shall no longer apply to such
Participant.

     Basic Contributions and Employer Contributions made to the Plan with
respect to a Participant who is eligible for the Pre-Retirement Feature
described in this Section 5.6 shall continue to be invested initially in shares
of Company Stock, but will be available for reinvestment in the SRP Stable Value
Fund or in any of the other Investment Funds described in Section 5.3 in
accordance with the procedures established under Section 5.7.

     The restrictions and transition rules described in this Section 5.6 shall
apply to the Accounts of all Participants, including, but not limited to, those
who have retired under the Abbott Laboratories Annuity Retirement Plan.

     5.7. INVESTMENT ELECTIONS.  Subject to Sections 5.1, 5.2, 5.4, 5.5 and 5.6,
a Participant, Beneficiary or Alternate Payee may make or change investment
instructions with respect to the portion of the Accounts over which he or she
has investment direction at such times and at such frequency as the
Administrator shall permit in accordance with investment procedures established
for the Plan.  Such investment instructions shall be in writing or in such other
form as is acceptable to the Trustee.

     5.8. DEFAULT INVESTMENT FUND.  The Administrator shall from time to time
identify one or more of the Investment Funds as the default Investment Fund into
which all contributions, for which the Participant has the right to direct
investment, shall be invested if the Participant fails to provide complete and
clear investment instructions for such contributions.  Such contributions shall
remain in the default Investment Fund until the Trustee receives investment
instructions from the Participant in a form acceptable to the Trustee.

     5.9. PARTICIPANT DIRECTION OF INVESTMENTS.  To the extent that this Article
5 does not prohibit a Participant, Beneficiary or Alternate Payee from directing
the investment of his or her Accounts, the Plan is intended to be a
participant-directed plan and to comply with the requirements of ERISA Section
404(c) and the Department of Labor Regulations 2550.404c-1 as a
participant-directed plan.  To the extent this Section 5.9 applies, the
Administrator shall direct the Trustee from time to time with respect to such
investments pursuant to the instructions of the Participant (or, if applicable,
the Alternate Payee, or the deceased Participant's Beneficiary), but the Trustee
may refuse to honor any investment instruction if such instruction would cause
the Plan to engage in a prohibited transaction (as described in Code section
4975(c)) or cause the Trust to be subject to income tax.  The Administrator
shall prescribe the form upon which, or such other manner in which such
instructions shall be made, as well as the frequency with which such
instructions may be made or changed and the dates as of which such instructions
shall be effective.  The Board of Review reserves the right to amend the Plan to
remove the right of Participants, 


                                    13



Beneficiaries or Alternate Payees to give investment instructions with 
respect to their Accounts.  Nothing contained herein shall provide for the 
voting of shares of Company Stock by any Participant, Beneficiary or 
Alternate Payee, except as otherwise provided in the Trust.

     5.10.     DIVIDENDS ON COMPANY STOCK.  Except with respect to shares of
Company Stock acquired during the Plan Year and held in the Unallocated Account,
cash dividends on shares of Company Stock shall be credited to the applicable
Accounts in which the shares are held and cash proceeds from the sale of any
rights or warrants received with respect to such Stock shall be invested in
shares of Company Stock when such dividends or proceeds are received by the
Trust, and thereafter such shares shall be credited to such Accounts based on
the average cost of all shares purchased with such dividends or proceeds. Stock
dividends or "split-ups" and rights or warrants appertaining to such shares
shall be credited to the applicable Accounts when received by the Trust.  Cash
dividends received with respect to shares of Company Stock held in the
Unallocated Account and cash proceeds from the sale of rights or warrants
received with respect to such Company Stock shall be reinvested in Company Stock
and allocated under Section 3.5, to the extent not used to pay expenses of the
Plan.  Any stock dividends or "split-ups" (and any rights or warrants unless
sooner sold) appertaining to shares of Company Stock held in the Unallocated
Account will be held in the Unallocated Account until the end of the Plan Year
and allocated under Section 3.5.

     5.11.     INVESTMENT OPTIONS FOR FORMER M&R EMPLOYEES.  Effective April 3,
1996 (or such subsequent date as the Administrator determines in his or her sole
discretion), Participants (and any Beneficiaries of deceased Participants or
Alternate Payees with respect to such Participants or deceased Participants) who
have Accounts formerly held in the M&R Retirement Trust ("M & R Accounts") and
who had special investment options described in Supplement A of the Prior Plan,
shall reinvest their Accounts in one or more of the investment options described
in Section 5.1, 5.2 and 5.3.  If at the end of the transition period established
by the Administrator for such reinvestment, any portion of a such M & R Accounts
has not been reinvested pursuant to the prior sentence, then the Administrator
shall direct the Trustee to liquidate the investments in such Accounts and
transfer the proceeds to one or more default investment funds designated by the
Administrator.

               ARTICLE 6. WITHDRAWALS PRIOR TO SEPARATION FROM SERVICE
                                           
     6.1. INSERVICE WITHDRAWALS OF AFTER-TAX CONTRIBUTIONS.  For purposes of
Code Section 72, all amounts held in a Participant's After-Tax Contribution
Accounts that are attributable to Basic or Supplemental After-Tax Contributions
made after 1986 (including earnings) shall be considered a "separate contract". 
In addition, for purposes of applying the withdrawal provisions set forth in
this Section 6.1(a), (b) and (c), a Participant's Accounts containing Company
Stock shall be separate and distinct from all other Investment Funds in such
Accounts, such that a Participant can elect under Sections 6.1(a), (b) and (c)
to withdraw all of the Participant's Company Stock without withdrawing any of
the other Investment Funds or all of the Participant's Investment Funds (in
other than Company Stock) without withdrawing any Company Stock, or any
combination of Company Stock or other Investment Funds as the Participant may
elect.  If the Participant's non-Company Stock funds are in more than one
Investment Fund, then such withdrawal shall be made proportionately from all
such Investment Funds.  Subject to the foregoing, a Participant 


                                    14


may elect to take a withdrawal from his or her After-Tax Contribution 
Accounts in accordance with the following conditions and order of priority:   
 

          (a)  PRE-1987 SUPPLEMENTAL AND BASIC AFTER-TAX CONTRIBUTIONS.  A
     Participant may withdraw from the Trust (i) in cash, any or all of his or
     her Supplemental and Basic After-Tax Contributions made prior to 1987
     and/or (ii) some or all of the shares of Company Stock purchased with such
     After-Tax Contributions.  If the Participant elects to receive any
     withdrawal in Company Stock or cash from Company Stock, such amounts will
     be withdrawn (i) from the Company Stock in the Supplemental After-Tax
     Contribution Account until exhausted and (ii) then from the Company Stock
     in the Basic After-Tax Contribution Account until exhausted.  If the
     Participant elects to receive any withdrawal in cash from the Investment
     Funds (other than Company Stock), such amounts shall be withdrawn (i) from
     the Investment Funds (other than Company Stock) in the Supplemental
     After-Tax Contribution Account until exhausted and (ii) then from the
     Investment Funds (other than Company Stock) in the Basic After-Tax
     Contribution Account until exhausted.

          (b)  POST-1986 SUPPLEMENTAL AND BASIC AFTER-TAX CONTRIBUTIONS (FIVE
     YEARS CREDITED SERVICE REQUIRED).   A Participant who has completed five or
     more Years of Credited Service and who has withdrawn all of his or her
     pre-1987 Supplemental and Basic After-Tax Contributions under subsection
     (a) may then withdraw from the Trust any or all of his or her Supplemental
     and Basic After-Tax Contributions made after 1986 and earnings thereon. 
     Withdrawals under this subsection (b) may be in cash or shares of Company
     Stock but shall not exceed the value of the Supplemental and Basic
     After-Tax Contribution Accounts that is attributable to the Participant's
     After-Tax Contributions made after 1986.  If the Participant elects to
     receive any withdrawal in Company Stock or cash from Company Stock, such
     amounts will be withdrawn (i) from the Company Stock in the Supplemental
     After-Tax Contribution Account until exhausted and (ii) then from the
     Company Stock in the Basic After-Tax Contribution Account until exhausted. 
     If the Participant elects to receive any withdrawal in cash from the
     Investment Funds (other than Company Stock), such amounts shall be
     withdrawn (i) from the Investment Funds (other than Company Stock) in the
     Supplemental After-Tax Contribution Account until exhausted and (ii) then
     from the Investment Funds (other than Company Stock) in the Basic After-Tax
     Contribution Account until exhausted.
 
          (c)  POST-1986 SUPPLEMENTAL AFTER-TAX CONTRIBUTIONS (LESS THAN FIVE
     YEARS CREDITED SERVICE REQUIRED).   A Participant who has not completed
     five or more Years of Credited Service and who has withdrawn all of his or
     her pre-1987 After-Tax Contributions (if any) under subsection (a) may then
     withdraw from the Trust any or all of his or her Supplemental After-Tax
     Contributions made after 1986 and earnings thereon.  Withdrawals under this
     subsection (c) may be in cash or shares of Company Stock but shall not
     exceed the value of the Supplemental After-Tax Contribution Account that is
     attributable to the Participant's Supplemental After-Tax Contributions made
     after 1986.  If the Participant elects to receive any withdrawal in Company
     Stock (or cash from Company Stock) such amount will be withdrawn from the
     Company Stock in the Supplemental After-Tax Contribution Account until
     exhausted.  If the Participant elects to receive any withdrawal in
     Investment Funds (other than Company Stock), such amount will be withdrawn


                                    15



     from the Investment Funds (other than Company Stock) in the Supplemental
     After-Tax Contribution Account.

          (d) REMAINDER OF AFTER-TAX CONTRIBUTION ACCOUNTS.  A Participant, who
     has withdrawn all of his or her After-Tax Contributions available under
     subsections (a), (b) and (c) in both Company Stock and in Investment Funds
     (other than Company Stock), may then withdraw from the Trust any or all of
     the amount remaining in his or her After-Tax Contribution Accounts (other
     than the Basic After-Tax Contribution Account, in the case of a Participant
     who has not completed five or more Years of Service).

          (e)  SOURCE OF WITHDRAWN AMOUNTS.  If the Participant elects to
     receive his or her withdrawal in shares of Company Stock held in his or her
     After-Tax Contribution Accounts, whole shares shall be distributed and the
     value of a fractional share necessary to exhaust the Company Stock
     allocated to such Accounts shall be distributed in cash. 

          (f)  PRE-1987 SHARES.  (i)  For purposes of Section 6.1(a), shares of
     Company Stock purchased with a Participant's Supplemental After-Tax
     Contribution made prior to 1987 shall be determined as follows:

               (A)  FIRST, the average cost to the Trust of all unwithdrawn
          shares of Company Stock purchased with Participant's Supplemental
          After-Tax Contributions made prior to 1987 and related dividends shall
          be established.

               (B)  NEXT, the total of the Participant's unwithdrawn
          Supplemental After-Tax Contributions made prior to 1987 and applied to
          the purchase of Company Stock (net of any such amounts that have been
          reinvested in Investment Funds other than Company Stock) shall be
          divided by the average cost established under subparagraph (A) above
          and the resulting amount shall be the number of shares of Company
          Stock purchased with the Participant's Supplemental After-Tax
          Contributions prior to 1987.

                    (ii)  For purposes of Section 6.1(a), shares of Company
               Stock purchased with a Participant's Basic After-Tax
               Contributions made prior to 1987 shall be determined as follows:

                         (A)  FIRST, the average cost to the Trust of all
               unwithdrawn    shares of Company Stock purchased with the
                              Participant's Basic After-Tax Contributions and
                              Employer contributions made prior to 1987 and
                              related dividends shall be established.

                         (B)  NEXT, the total of the Participant's unwithdrawn
                    Basic After-Tax Contributions made prior to 1987 and applied
                    to the purchase of Company Stock (net of any such amounts
                    that have been reinvested in Investment Funds other than
                    Company Stock) shall be divided by the average cost
                    established under subparagraph (A) above and the resulting
                    amount shall be the number of shares purchased with the
                    Participant's Basic After-Tax Contributions made prior to
                    1987.


                                    16




                    (iii)  For purposes of determining a Participant's
               unwithdrawn Basic After-Tax Contributions and Supplemental
               After-Tax Contributions made prior to 1987, any shares of Company
               Stock purchased with the Participant's Supplemental After-Tax
               Contributions made prior to 1987 that were withdrawn by the
               Participant as of any date shall be charged at the average cost
               established under subparagraph (i)(A) above as of such date, and
               any shares of Company Stock purchased with the Participant's
               Basic After-Tax Contributions made prior to 1987 that were
               withdrawn by the Participant as of any date shall be charged at
               the average cost established under subparagraph (ii)(A) above as
               of such date.

               (g)  WITHDRAWAL PROCEDURES.  The foregoing provisions of this
          Section 6.1 are subject to the following:

                    (i)  Shares of Company Stock and other amounts that are
               withdrawn by a Participant under this Section 6.1 shall be
               charged to his or her respective After-Tax Contribution Account.

                    (ii)  No more than one withdrawal may be elected in any
               ninety-day period; provided, however, that the Administrator, in
               his or her sole discretion, may waive this limitation in unusual
               cases.

                    (iii)  Distribution of the shares of Company Stock or other
               amounts a Participant elects to withdraw under this Section 6.1
               shall be made within such time period and in accordance with the
               procedures established by the Administrator and agreed to by the
               Trustee.  If the Participant dies prior to the time distribution
               of such shares or amounts is made, distribution shall be made to
               the Participant's Beneficiary in the same manner as other
               distributions from the Trust.

                    (iv)  Each request for a withdrawal shall be filed with the
               Administrator, shall specify either the dollar amount or the
               share amount (or both) to be withdrawn, the value of which amount
               shall not be less than $500, and may not be revoked, amended or
               changed by the Participant after it is filed. The Participant
               shall indicate in his or her withdrawal request whether the
               withdrawal is to be made in cash or shares of Company Stock.

                    (v)  Any check or certificate fees associated with a
               withdrawal will be charged to the Participant's Account.

                    (vi)  Withdrawals under this Section 6.1 shall be subject to
               such further conditions and limitations as the Administrator may
               establish from time to time and apply on a uniform basis.

                    (vii)  Any shares of Company Stock that are withdrawn shall
               be considered as having been withdrawn at the average cost, as of
               the date of the withdrawal, of the shares of Company Stock
               reflected in the Account from which  they were withdrawn. 


                                    17


               (h)  WITHDRAWAL PRIORITY.  Withdrawals under this Section 6.1 may
          be in a different order of priority and subject to such further
          conditions and limitations as the Administrator may establish from
          time to time and apply on a uniform basis.

     6.2.  INSERVICE WITHDRAWALS OF CERTAIN ROLLOVER CONTRIBUTIONS.  A
Participant who is a MediSense Employee (as defined in Section 15.34(e)) and for
whom the Plan maintains a MediSense Rollover Contribution Account (as defined
below) may withdraw funds from his or her MediSense Rollover Contribution
Account; provided, however, that the Participant may request only two such
withdrawals in any Plan Year and that each withdrawal be made in accordance with
such administrative rules and practices as may be adopted by the Administrator. 
The term "MediSense Rollover Contribution Account" shall mean a rollover
contribution account that was previously maintained for the Participant under
the MediSense 401(k) plan and that was established under the Plan in connection
with the transfer of the plan assets of the MediSense 401(k) plan to the Plan.  

          6.3.  WITHDRAWALS AT AGE 59 1/2 FROM A MEDISENSE TRANSFER CONTRIBUTION
ACCOUNT.  Upon having reached age 59 1/2, a Participant who is a MediSense
Employee (as defined in Section 15.34(e)) and for whom the Plan maintains a
MediSense Transfer Contribution Account (as defined below) may withdraw funds
from his or her MediSense Transfer Contribution Account.  Each withdrawal
described in this section shall be made in accordance with such administrative
rules and practices as may be adopted by the Administrator.  The term "MediSense
Transfer Contribution Account" shall mean a Transfer Contribution Account
maintained for the Participant under the Plan in connection with the transfer of
the plan assets of the MediSense 401(k) plan to the Plan.  The term "MediSense
Account" shall mean both a MediSense Transfer Contribution Account and a
MediSense Rollover Contribution Account.     

     6.4. REQUIRED DISTRIBUTIONS AFTER AGE 70.  Except as provided in the next
sentence, a Participant who remains an Employee on or after his or her "required
beginning date" (within the meaning of Code section 401(a)(9)) while an Employee
shall receive a distribution of the full value of his or her Accounts as of the
date any distribution under Code section 401(a)(9) would be required.  Any
Participant (other than a 5% owner of the Corporation, an Affiliated
Corporation, or a Subsidiary in the year such owner attains age 66 and any
subsequent year) who attained age 70 before January 1, 1988 may defer receipt of
the distributions under this Section 6.4 until the April 1 following the
calendar year in which he or she retires or attains age 70, whichever is later. 
Each distribution described in this Section 6.4 shall be made at the latest
possible date permitted under Code section 401(a)(9) and Regulations thereunder
and in accordance with such administrative rules and practices as may be adopted
by the Administrator.

     6.5. DISTRIBUTIONS REQUIRED BY A QUALIFIED DOMESTIC RELATIONS ORDER.  To
the extent required by a Qualified Domestic Relations Order, the Administrator
shall make distributions from a Participant's Accounts to Alternate Payees named
in such order in a manner consistent with the distribution options otherwise
available under this Plan, regardless of whether the Participant is otherwise
entitled to a distribution at such time under the Plan.  

     6.6.  PARTICIPANT'S CONSENT TO DISTRIBUTION OF BENEFITS AND DIRECT ROLLOVER
NOTICE.  If a Participant receives a withdrawal under Section 6.1, 6.2, 6.3, or
6.4 or an Alternative Payee receives a distribution under Section 6.5, no
distribution may be made unless:


                                    18


               (a)  between the 30th and 90th day prior to the date distribution
          is to be made or commence, the Administrator notifies the Participant
          or the Alternate Payee (whichever is applicable) in writing that he or
          she may defer distribution until the April 1 after the Plan Year in
          which he or she attains age 70 and provides the Participant or the
          Alternate Payee (whichever is applicable) with a written description
          of the material features and (if applicable) the relative values of
          the forms of distribution available under the Plan including the right
          to make a direct rollover under Section 8.3(d); and

               (b)  the Participant consents to the distribution in writing
          after the information described above has been provided to him or her,
          and files such consent with the Administrator.  Distribution to the
          Participant will be made or commence as soon as practicable after such
          consent is received by the Administrator.  The Participant may waive
          the 30-day notice period described in (a) above.

                          ARTICLE 7.  LOANS TO PARTICIPANTS
                                           
     7.1. IN GENERAL.  Upon the request of an Eligible Borrower on a form
approved or procedure prescribed by the Administrator and subject to the
conditions of this Article, the Administrator shall direct the Trustee to make a
loan from the Trust to the Eligible Borrower.  For purposes of this Article, an
"Eligible Borrower" is:

          (a)  a Participant who is an Eligible Employee; or

          (b)  a Participant who is a former Employee and is a "party in
     interest" within the meaning of ERISA section 3(14); or 

          (c)  a deceased Participant's Beneficiary who has not yet received the
     entire vested portion of the Participant's Accounts and who is a "party in
     interest" as described in (b) above.

     7.2. RULES AND PROCEDURES.  The Administrator shall promulgate such rules
and procedures, not inconsistent with the express provisions of this Article, as
he or she deems necessary to carry out the purposes of this Article.  All such
rules and procedures shall be deemed a part of the Plan for purposes of the
Department of Labor's Regulations Section 2550.408b-1(d).

     7.3. MAXIMUM AMOUNT OF LOAN.  The following limitations shall apply in
determining the amount of any loan to an Eligible Borrower hereunder:

          (a)  The amount of the loan, together with any other outstanding
     indebtedness under this Plan or any other qualified retirement Plan of the
     Corporation, any Affiliated Corporation or any Subsidiary, shall not exceed
     $50,000 reduced by the excess of (i) the highest aggregate outstanding loan
     balance of the Eligible Borrower from such Plans during the one-year period
     ending on the day prior to the date on which the loans are made, over (ii)
     the Eligible Borrower's outstanding loan balance from such Plans
     immediately prior to the loan.


                                    19


          (b)  The amount of the loan shall not exceed 50 percent of the
     Eligible Borrower's Accounts, determined as of the date of the loan.

          (c)  No loan may exceed the aggregate value of the Participant's Basic
     Pre-Tax Contribution Account, Supplemental Pre-Tax Contribution Account,
     Employer Contribution Account, Rollover Contribution Account and Transfer
     Contribution Account (excluding any amount contributed by the Participant
     on an after-tax basis).

     7.4. MINIMUM AMOUNT OF LOAN; NUMBER OF LOANS; FREQUENCY OF LOANS; FEES FOR
LOANS.  The minimum amount of any single loan under the Plan shall be $1,000.  A
Participant may have only two loans outstanding at any time under the Plan or
under any other plan referred to in Section 3.5.  The Administrator may charge a
loan fee and such fee may be charged to the Participant's Accounts or taken from
the loan proceeds.

     7.5. NOTE; SECURITY; INTEREST.  Each loan shall be evidenced by a note
signed by the Eligible Borrower, a Participant Credit Agreement, or other
legally enforceable evidence of indebtedness ("Note").  The Note shall be an
asset of the Trust which shall be allocated to the Accounts of the Eligible
Borrower, and shall for purposes of the Plan be deemed to have a value at any
given time equal to the unpaid principal balance of the Note plus the amount of
any accrued but unpaid interest.  The Note shall be secured by that portion of
the Accounts represented by the Note (not to exceed 50% of the Eligible
Borrower's vested interest in his or her Accounts determined as of the date of
the loan).  The loan shall bear interest at an annual percentage interest rate
to be determined by the Administrator.  In determining the interest rate, the
Administrator shall take into consideration interest rates currently being
charged by persons in the business of lending money with respect to loans made
in similar circumstances.  

     7.6. REPAYMENT.  Each loan made to an Eligible Borrower who is receiving
regular payments of Compensation from the Corporation shall be repayable by
payroll deduction.  Loans made to other Eligible Borrowers (and, in all events,
where payroll deduction is no longer practicable) shall be repayable in such
manner as the Administrator may from time to time determine.  In each case
payments shall be made not less frequently than quarterly, over a specified term
(as determined by the Administrator) not to extend beyond the earlier of five
years from the date of the loan or the Participant's anticipated retirement
date, with substantially level amortization (as that term is used in Code
section 72(p)(2)(C)).  Where the loan is being applied toward the purchase of a
principal residence for the Eligible Borrower, the term for repayment shall not
extend beyond the earlier of 15 years from the date of the loan or the
Participant's anticipated retirement date.  An Eligible Borrower may prepay the
full balance of an outstanding loan at any time by delivering to the Trustee a
certified check in the amount of such remaining balance and any accrued but
unpaid interest.  An Eligible Borrower may also refinance an outstanding loan,
provided the limits under Section 7.3 allow the Borrower to borrow an amount
equal to, or greater than the balance due on the outstanding loan.

     7.7. REPAYMENT UPON DISTRIBUTION.  If, at the time benefits are to be
distributed (or to commence being distributed) to an Eligible Borrower with
respect to a separation from service, there remains any unpaid balance of a loan
hereunder, such unpaid balance shall, to the extent consistent with Department
of Labor regulations, become immediately due and payable in full.  Such unpaid
balance, together with any accrued but unpaid interest on the loan, shall be
deducted from the Eligible Borrower's Accounts, subject to the default


                                    20



provisions below, before any distribution of benefits is made.  Except as is
provided in Section 7.1 or as may be required in order to comply (in a manner
consistent with continued qualification of the Plan under Code section 401(a))
with Department of Labor regulations, no loan shall be made to an Eligible
Borrower under this Article after the Eligible Borrower incurs a separation from
service whether or not he or she has begun to receive distribution of his or her
Accounts.

     7.8. DEFAULT.  In the event of a default in making any payment of principal
or interest when due under the Note evidencing any loan under this Article, if
such default continues for more than 90 days after written notice of the default
by the Trustee, the unpaid principal balance of the Note shall immediately
become due and payable in full.  Such unpaid principal, together with any
accrued but unpaid interest, shall thereupon be deducted from the Eligible
Borrower's Accounts, subject to the further provisions of this Section.  The
amount so deducted shall be treated as distributed to the Eligible Borrower and
applied by the Eligible Borrower as a payment of the unpaid interest and
principal (in that order) under the Note evidencing such loan.  In no event
shall the Administrator apply the Eligible Borrower's Accounts to satisfy the
Eligible Borrower's repayment obligation, whether or not he or she is in
default, unless the amount so applied otherwise could be distributed in
accordance with the Plan.  Default distributions under this Section 7.8 shall be
subject to such further conditions and limitations as the Administrator may
establish from time to time and apply on a uniform basis.

     7.9. NONDISCRIMINATION.  Loans shall be made available under this Article
to all Eligible Borrowers on a reasonably equivalent basis.

     7.10.     SOURCE OF LOAN PROCEEDS.  The proceeds for a loan shall be drawn
first from the Eligible Borrower's Supplemental Pre-Tax Contribution Account,
then from his or her Rollover Contribution Account established pursuant to
Section 12.1 (if any), then from his or her Transfer Contribution Account
established pursuant to Section 12.4 (if any), then from his or her Basic
Pre-Tax Contribution Account, and then from his or her Employer Contribution
Account, in each case drawing proportionately from the Investment Funds (other
than Company Stock) in which the applicable Account is invested until such
Investment Funds are exhausted, and then drawing from the applicable Account the
Company Stock held in each such Account.

     7.11.     REINVESTMENT OF LOAN REPAYMENTS.  Loan repayments shall be made
to the Eligible Borrower's Accounts from which the proceeds were drawn under
Section 7.10 in proportion that the loan was taken from each such Account at the
origination of the loan.  Within each such Account, the proceeds will be
invested in accordance with the investment instructions or restrictions
applicable at the time of each loan repayment.  If the Eligible Borrower is not
currently making contributions to any such Account at the time of loan
repayment, the proceeds will be invested within such Account in accordance with
any previous  instructions on file with the Trustee for the investment of
contributions in such Account, and if there are no such instructions on file,
the proceeds will be invested in the default Investment Fund(s) then in effect
under Section 5.8.  The Participant may change his or her investment
instructions in accordance with Section 5.7 for purposes of reinvesting the loan
repayments even if he or she is not then making contributions to the Plan.  All
such proceeds (other than proceeds repaid to and invested in a Basic Pre-Tax
Contribution Account or an Employer Contribution Account by a Participant who
has not yet reached the age of 50) shall for purposes of  Sections 5.4, 5.5 and
5.6 be considered to be 


                                    21


unrestricted as to investment and may be invested in any of the Investment 
Funds then available under the Plan.

                   ARTICLE 8.  BENEFITS UPON RETIREMENT, DEATH OR 
                               SEPARATION FROM SERVICE
                                           
     8.1. RETIREMENT OR SEPARATION FROM SERVICE FOR REASONS OTHER THAN DEATH. 
Following a Participant's retirement or separation from the service with the
Corporation, all Affiliated Corporations and all Subsidiaries for any reason
other than death, the Participant will receive the value of his or her Accounts
in a single sum payment unless he or she elects an annuity under Section 8.3 (b)
or a direct rollover under Section 8.3(d).  To the extent that the Participant's
Accounts hold Company Stock, he or she may receive the distribution in whole
shares of Company Stock and cash for any fractional share.

     8.2. TIME OF DISTRIBUTIONS.  Distribution with respect to a Participant's
separation from service (other than on account of death or retirement) normally
will be made or commence as soon as practicable after such separation. The
Employer Contribution made on the Participant's behalf under Section 3.5 for the
Plan Year will be based on the Point Value determined for the prior Plan Year
and distributed to the Participant in cash or Company Stock, at the
Participant's election.  Except as provided in the last sentence of this Section
8.2, in the case of a Participant whose Accounts are valued in excess of $3,500
and who has not yet attained age 65, however, distribution may not be made under
this Section unless:

          (a)  between the 30th and 90th day prior to the date distribution is
     to be made or commence, the Administrator notifies the Participant in
     writing that he or she may defer distribution until the April 1 after the
     Plan Year in which he or she attains age 70 and provides the Participant
     with a written description of the material features and (if applicable) the
     relative values of the forms of distribution available under the Plan; and

          (b)  the Participant consents to the distribution in writing after the
     information described above has been provided to him or her, and files such
     consent with the Administrator.  Distribution to the Participant will be
     made or commence as soon as practicable after such consent is received by
     the Administrator.  The Participant may waive the 30-day notice period
     described in (a) above.

The value of a Participant's Accounts will be considered to be in excess of
$3,500 if the value exceeds such amount at the time of the distribution in
question or exceeded such amount at the time of any prior distribution to the
Participant under the Plan.   The Participant may elect to defer the
distribution of his or her Accounts until any subsequent date, but not later
than the April 1 after the Plan Year in which he or she attains age 70.

     A Participant who is eligible for retirement under the terms of the Abbott
Laboratories Annuity Retirement Plan will normally receive a distribution as
soon as practicable after the end of the Plan Year in which he or she retires
and following the crediting of the Employer Contribution determined under
Section 3.5 for such Plan Year.  Such Participant may elect to receive the
distribution in the calendar year in which he or she retires, in which event the
Employer Contribution made on the Participant's behalf under Section 3.5 will be
based on the Point Value determined for the prior Plan Year and 


                                    22


distributed to the Participant in cash.  Alternatively, the Participant may 
elect to defer the distribution of his or her Accounts until any date, but no 
later than the April 1 after the Plan Year in which he or she attains age 70.

     8.3. AMOUNT AND MANNER OF DISTRIBUTION.  A Participant who is eligible for
a distribution from the Plan under this Article 8, may, subject to subsection
(c), elect to receive his or her benefit in one or more of the following forms:

          (a)  SINGLE SUM PAYMENT.  In the case of a distribution to be made in
     a single sum, the amount of such distribution shall be determined as of the
     Valuation Date which immediately precedes or coincides with the date
     distribution is to be made.

          (b)  ANNUITY PURCHASED FOR CERTAIN AMOUNTS.  Monthly payments may 
     be made from a single premium annuity contract purchased for the 
     Participant with all or any portion of the value of the following 
     Accounts: (i) for all Participants, the value of the Participant's 
     Accounts as of December 31, 1995 and (ii) for a Participant who is a 
     MediSense Employee (as defined in Section 15.34(e)) the value of that 
     Participant's MediSense Account (as defined in Section 6.3) as of August 
     1, 1997.  The provisions of such annuity contract shall be subject to the 
     following:

               (A)  With respect to those Participants described in Section
          8.3(b)(i), the payment forms under an annuity contract shall include:
          (1) an annuity payable for the life of the Participant; (2) an annuity
          payable for life with a refund feature; (3) an annuity payable over
          the joint lives of the Participant and another person designated by
          the Participant, provided such person (if not the Participant's
          spouse) is not more than 30 years younger than the Participant; or (4)
          an annuity payable for life and a period provided such period certain
          does not extend beyond the Participant's 85th birthday.

               (B)  With respect to those Participants described in Section
          8.3(b)(ii), the payment forms under an annuity contract shall include:
          (1) an annuity payable for the life of the Participant; (2) an annuity
          payable for the life of the Participant with a refund feature; (3) an
          annuity payable over the joint lives of the Participant and another
          person designated by the Participant, provided such person (if not the
          Participant's spouse) is not more than 30 years younger than the
          Participant; or (4) an annuity payable for the greater of the
          Participant's life or 120 monthly payments.

               (C)  Each such annuity contract shall be nontransferable except
          by surrender to the issuing insurance company and shall provide for a
          monthly payment of not less than twenty five dollars ($25).

               (D)  The Administrator may cause an annuity contract to be
          assigned or delivered to the person or persons then entitled to
          payments under it, but prior to the assignment or delivery of an
          annuity contract, it shall be rendered nontransferable and, at the
          Administrator's discretion, may be rendered non-commutable.

               (E)  Beginning January 1, 1985, if a Participant is married on
          his or her Annuity Starting Date, and the Participant has elected to
          have his or her benefits distributed by purchase of an annuity
          contract, the value of the Participant's 


                                    23


          Accounts (or MediSense Account, as the case may be) will be applied 
          to purchase a joint and survivor annuity (as defined herein), 
          unless the Participant has made an election to waive that form of 
          annuity.  A "joint and survivor annuity" is an annuity payable for 
          the life of the Participant, with a survivor annuity payable for 
          the life of his or her spouse of one-half of the amount payable 
          during the joint lives of the Participant and his or her spouse.  A 
          Participant may make a written election to waive the joint and 
          survivor annuity at any time during the 90-day period ending on his 
          or her Annuity Starting Date.  Such an election will be effective 
          only if the Participant's spouse consents to the election in 
          writing, and such consent acknowledges the effect of the waiver and 
          is witnessed by a Plan representative or a notary public.  Within a 
          reasonable time before a Participant's Annuity Starting Date, the 
          Administrator shall provide the Participant with a written 
          explanation of the terms and conditions of the joint and survivor 
          annuity, the Participant's right to make, and the effect of, a 
          revocation of such a waiver.  An election under this subsection may 
          be revoked by a Participant at any time prior to his or her Annuity 
          Starting Date.  If a Participant has elected to waive the joint and 
          survivor annuity, his or her Account balances will be distributed 
          under one of the annuity forms of payment described in Section 
          8.3(b)(i) or 8.3(b)(ii) above, as the Participant elects.
          
          (c)  CASHOUT OF SMALL BENEFITS.  If the value of a Participant's 
    Accounts is $3,500 or   less, distribution shall be made to the 
    Participant in a single sum payment as soon as practicable following the 
    Participant's separation from service.  The amount of such distribution 
    shall be determined as of the Valuation Date immediately preceding or 
    coinciding with the date the distribution is to be made.  The 
    Participant's Accounts will not be considered to be valued at $3,500 or 
    less, if the value of such Accounts at the time in question or at the 
    time of any prior distribution to the Participant under the Plan exceeds 
    such amount.

          (d)  DIRECT ROLLOVER OF ELIGIBLE ROLLOVER DISTRIBUTIONS.  If a
     Participant or an Alternate Payee of the Participant is entitled to an
     eligible rollover distribution within the meaning of Code section 402(c)(4)
     under (a) or (b) above, he or she may elect to have all or a portion of
     such distribution (but not less than the minimum amount required to be
     transferred under Treasury regulations pertaining to the treatment of
     eligible rollover distributions) transferred to another qualified plan, an
     individual retirement account, or an individual retirement annuity, or any
     other eligible retirement plan within the meaning of Code section
     402(c)(8)(B).  Such distribution may be made in the form of a direct
     rollover or by other means prescribed by regulations which satisfy the
     requirements for a direct payment to the eligible retirement plan so
     specified.  The Administrator shall not be obliged to honor any transfer
     instruction under this Section that specifies more than one transferee.

     8.4. DISTRIBUTIONS AFTER A PARTICIPANT'S DEATH.

          (a)  DEATH PRIOR TO SEPARATION FROM SERVICE.  If a Participant dies
     prior to his or her separation from the service with the Corporation, all
     Affiliated Corporations and all Subsidiaries, the Participant's Beneficiary
     will receive the Participant's Accounts in a single sum payment as soon as
     practicable after the end of the Plan Year in which the Participant's death
     occurs; provided, however, the Beneficiary may elect to receive the
     distribution in the Plan Year in which the Participant's death occurred, in
     which event the Employer Contribution made on behalf of the Participant
     under Section 


                                    24



     3.5 for such Plan Year shall be based on the Point Value
     determined for the prior Plan Year and shall be distributed in cash. 
     Distribution must be made to a Beneficiary who is not the Participant's
     spouse no later than December 31 of the calendar year following the year of
     the Participant's death.  If the Beneficiary is the Participant's spouse,
     the Beneficiary may elect to defer receipt of the distribution of the
     Participant's Accounts until any date, but no later than the December 31 of
     the Plan Year in which the Participant would have attained age 70 1/2.

          (b)  DEATH AFTER SEPARATION FROM SERVICE.  If a Participant dies after
     separation from service but before the complete distribution of his or her
     Accounts has been made, the Participant's Beneficiary will receive the
     value of the Participant's Accounts.  Distribution will be made in a single
     sum payment as soon as practicable after the Participant's death (but no
     later than December 31 of the calendar year following the year of the
     Participant's death); provided, however, that if distribution to the
     Participant had begun following his or her separation from service in a
     form elected by the Participant, distribution will continue to be made to
     the Beneficiary at least as rapidly in such form unless the Beneficiary
     elects to receive distribution in cash in a single sum as soon as
     practicable following the Participant's death.  Any such election must be
     made on a form approved by the Administrator and must be received by the
     Administrator within such period following the Participant's death as the
     Administrator may prescribe.  To the extent the Participant's Accounts held
     Company Stock at the time of the proposed distribution, the Beneficiary may
     receive the distribution in whole shares of Company Stock and cash for any
     fractional share.  

          (c)  CASHOUT OF SMALL BENEFITS.  If a Participant dies and the value
     of a Participant's Accounts is $3,500 or less, distribution shall be made
     to the Beneficiary in a single sum payment as soon as practicable following
     the Participant's death (but in no event later than the 60th day following
     the close of the Plan Year in which such death occurs) or such later date
     on which the amount of the distribution can be determined by the
     Administrator.  The amount of such distribution shall be determined as of
     the Valuation Date immediately preceding or coinciding with the date the
     distribution is to be made. The Participant's Accounts will not be
     considered to be valued at $3,500 or less, if the value of such Accounts at
     the time in question or at the time of any prior distribution to the
     Participant under the Plan exceeds such amount.

          (d)  DIRECT ROLLOVER OF ELIGIBLE ROLLOVER DISTRIBUTIONS.  If a
     Beneficiary who is the spouse of a deceased Participant is entitled to an
     eligible rollover distribution within the meaning of Code section 402(c)(4)
     under (a) or (b) above, he or she may elect to have all or a portion of
     such distribution (but not less than the minimum amount required to be
     transferred under Treasury regulations pertaining to the treatment of
     eligible rollover distributions) transferred to an individual retirement
     account or an individual retirement annuity.  Such distribution may be made
     in the form of a direct rollover or by other means prescribed by
     regulations which satisfy the requirements for a direct payment to the
     eligible retirement plan so specified.  The Administrator shall not be
     obliged to honor any transfer instruction under this Section that specifies
     more than one transferee.


                                    25




Any distribution to a Beneficiary under this Section in the form of a single sum
shall be determined as of the Valuation Date immediately preceding or coinciding
with the date distribution is to be made.

     8.5. DESIGNATION OF BENEFICIARY.  Subject to the provisions of this
Section, a Participant's Beneficiary shall be the person or persons (or entity
or entities), if any, designated by the Participant from time to time on a form
or in a manner approved by the Administrator.  In the absence of an effective
Beneficiary designation, a Participant's Beneficiary shall be his or her
surviving spouse, if any, or if none, the Participant's issue, or if none, the
Participant's estate.  A non-spouse Beneficiary designation by a Participant who
is married at the time of his or her death shall not be effective unless

          (a)  prior to the Participant's death, the Participant's surviving
     spouse consented to and acknowledged the effect of the Participant's
     designation of a specific non-spouse Beneficiary (including any class of
     Beneficiaries or any contingent Beneficiaries) in a written form approved
     by the Administrator and witnessed by a notary public or Plan
     representative; or

          (b)  it is established by the Participant prior to his or her death
     (by furnishing the Administrator with a sworn statement), that the required
     consent may not be obtained because there is no spouse, because the spouse
     cannot be located, or because of such other circumstances as the Secretary
     of the Treasury may prescribe; or

          (c)  the spouse had earlier executed a general consent form permitting
     the Participant (i) to select from among certain specified persons without
     any requirement of further consent by the spouse (and the Participant
     designates a Beneficiary from the specified list), or (ii) to change his or
     her Beneficiary without any requirement of further consent by the spouse. 
     Any such general consent shall be on a form approved by the Administrator,
     and must acknowledge that the spouse has the right to limit consent to a
     specific Beneficiary and that the spouse voluntarily elects to relinquish
     such right.

Any consent and acknowledgment by a spouse, or the establishment that the
consent and acknowledgment cannot be obtained, shall be effective only with
respect to such spouse, but shall be irrevocable once made.

                              ARTICLE 9.  ADMINISTRATION
                                           
     9.1. BOARD OF REVIEW.  The Board of Review, except where such are
specifically reserved to the Board of Directors, shall have all powers, duties
and obligations (whether imposed, granted or reserved and whether explicit or
implicit) which are lodged in the Corporation under the Trust, or the Plan, or
any supplement to the Plan or by law or regulations.  It shall perform all
functions specifically assigned to it under the Plan and under the Trust created
pursuant to the Plan.  The Board of Review at its sole discretion may delegate
or redelegate any responsibility which it is able to exercise, and may revoke
such delegations at its sole discretion.

     9.2. ADMINISTRATOR.  The Administrator will be the "administrator" of the
Plan as defined in Section 3(16)(A) of ERISA and a "named fiduciary" for
purposes of Section 402(a)(1) of ERISA with authority to control and manage the
operation and administration


                                    26




of the Plan, and will be responsible for complying with all of the reporting 
and disclosure requirements of Part 1 of Subtitle B of Title I of ERISA.  The 
Administrator will not, however, have any authority over the investment of 
assets of the Trust or the selection of Investment Funds.

     9.3.  POWERS OF ADMINISTRATOR.  The Administrator will have full power to
administer the Plan in all of its details and, other than the selection of
Investment Funds, subject, however, to the requirements of ERISA.  For this
purpose the Administrator's power will include, but will not be limited to, the
following discretionary authority:

               (a)  to make and enforce such rules and regulations as the
          Administrator deems necessary or proper for the efficient
          administration of the Plan or as required to comply with applicable
          law;

               (b)  to interpret and enforce the Plan in accordance with the
          terms of the Plan (including the rules and regulations adopted under
          subsection (a)) and to make factual determinations thereunder,
          including the discretionary power to determine the rights or
          eligibility of Employees or Participants and any other persons, and
          the amount, if any, of their benefits under the Plan, and to construe
          or interpret disputed, ambiguous, or uncertain terms;

               (c)  to compute the amounts to be distributed under the Plan, to
          determine the person or persons to whom such amounts are to be
          distributed, and to make equitable adjustments for mistakes or errors;

               (d)  to authorize the payment of distributions, to compromise and
          settle any disputed claim, and to direct the Trustee to make such
          payments from the Trust;

               (e)  to keep such records and submit such filings, elections,
          applications, returns or other documents or forms as may be required
          under the Code, ERISA and applicable regulations, or under other
          federal, state or local law and regulations;

               (f)  to allocate and delegate the ministerial duties and
          responsibilities of the Administrator and to appoint such agents,
          counsel, accountants, consultants, actuaries, insurance companies and
          other persons as may be required or desired to assist in administering
          the Plan;

               (g )  by written instrument, to allocate and delegate his or
          her fiduciary responsibilities in accordance with ERISA section
          405; and

               (h)  to furnish each Employer with such information and data as
          may be required by it for tax and other purposes in connection with
          the Plan.

          Actions taken in good faith by the Administrator shall be binding and
          conclusive on all parties.    

     9.4. NONDISCRIMINATORY EXERCISE OF AUTHORITY.  Whenever, in the
administration of the Plan, any discretionary action by the Administrator is
required, the Administrator shall exercise his or her authority in a
nondiscriminatory manner so that all persons similarly situated will receive
substantially the same treatment.

                                      27


     9.5. RELIANCE ON TABLES, ETC.  In administering the Plan, the Administrator
will be entitled, to the extent permitted by law, to rely conclusively on all
tables, valuations, certificates, opinions and reports which are furnished by
any accountant, trustee, counsel, actuary, insurance company or other expert who
is employed or engaged by the Administrator or by the Corporation on the
Administrator's behalf.

     9.6. CLAIMS AND REVIEW PROCEDURES.  The Administrator shall adopt
procedures for the filing and review of claims in accordance with ERISA section
503.

     9.7. INDEMNIFICATION.  The Corporation agrees to indemnify and defend to
the fullest extent of the law any of its employees or former employees who
serves or has served as Administrator or as a member of the Board of Review or
who has been appointed to assist the Administrator or the Board of Review in
administering the Plan or to whom the Administrator or the Board of Review has
delegated any duties or responsibilities against any liabilities, damages, costs
and expenses (including attorneys' fees and amounts paid in settlement of any
claims approved by the Corporation) occasioned by any act or omission to act in
connection with the Plan, if such act or omission to act is in good faith.

     9.8. EXPENSES AND COMPENSATION.  No compensation shall be paid to the
Administrator or any assistant who is a full-time employee of the Corporation,
an Affiliated Corporation or a Subsidiary, but the Administrator and his or her
assistants shall be reimbursed for all expenses reasonably incurred in the
administration of the Plan.  Such expenses shall be charged to the Trust and
paid first out of the dividends paid on Company Stock held in the Unallocated
Account and then from Employer Contributions prior to allocation under Section
3.5, unless the Employers pay such expenses directly.  To the extent that any
recordkeeping expense, withdrawal charge, loan fee or check fee is specifically
attributable to a Participant's Accounts, such expenses may be charged to the
Accounts of such Participant.

     9.9. NOTICES; PARTICIPANT INFORMATION.  Any notice required to be given to
or any document required to be filed with the Administrator, the Trustee or a
Co-Trustee will be given or filed properly if mailed by registered mail, postage
prepaid, or delivered, to the Administrator, the Trustee or Co-Trustees, as the
case may be, in care of the Corporation at Abbott Park, Illinois.  Participants
(and their Beneficiaries) must furnish to the Administrator such evidence, data,
or information as they consider necessary or desirable for the purpose of
administering the Plan, and the provisions of the Plan for each person are upon
the condition that he or she will furnish full, true and complete evidence, data
and information requested by the Administrator.

                        ARTICLE 10.  AMENDMENT AND TERMINATION
                                           
     10.1.     AMENDMENT.  The Corporation reserves the power (and may and
hereby does  specifically delegate a portion of the power to the Board of
Review) at any time or times to amend the provisions of the Plan and Trust to
any extent and in any manner that it may deem advisable.  The Corporation
specifically reserves the right to amend Article 5 with respect to the
investment of Participant Accounts.  However, the Corporation will not have the
power:

                                      28


          (a)  to amend the Plan or Trust in such manner as would cause or
     permit any part of the assets of the Trust to be diverted to purposes other
     than for the exclusive benefit of each Participant and his or her
     Beneficiary (except as permitted by Section 14.3 with respect to Qualified
     Domestic Relations Orders, or by Section 3.9 with respect to the return of
     contributions upon nondeductibility or mistake of fact), unless such
     amendment is required or permitted by law, governmental regulation or
     ruling; or

          (b)  to amend the Plan or Trust retroactively in such a manner as
     would reduce the accrued benefit of Code Section 411(d)(6)) of any
     Participant, except as otherwise permitted or required by law; or

          (c)  to change the duties or liabilities of the Trustee, a Co-Trustee
     or the Administrator without their consent.

     All major amendments and all decisions or amendments which are reasonably
expected to have the effect of suspending or terminating Employer contributions,
of suspending or terminating payment of benefits to Participants or
Beneficiaries, or of terminating the Plan shall be made by the Board of
Directors.  All other amendments shall be made by the Board of Review.  The
Board of Directors may delegate additional authority to the Board of Review.

     For the purposes of the foregoing, a "major amendment" is defined to be any
amendment which will increase the average cost of the Plan to the Employers
(whether through the increase of Employer contributions or otherwise) by an
amount in excess of $500,000 per annum over the three full Plan Years next
succeeding the effective date of the amendment.  Determination of whether an
amendment is a major amendment or a decision or amendment which is reasonably
"to have the effect of suspending or terminating Employer contributions, of
suspending or terminating payment of benefits, or of terminating the Plan" shall
be made by the Board of Review after obtaining such advice from such legal or
tax counsel and the advice of such actuarial consultants as the Board of Review
may deem appropriate.  The secretary of the Board of Review shall maintain
detailed minutes reflecting the advice (if any) so received by the Board of
Review and the decisions reached by it regarding each amendment adopted by it.

     10.2.     TERMINATION.  The Corporation has established the Plan and
authorized the establishment of the Trust with the bona fide intention and
expectation that contributions will be continued indefinitely, but the
Corporation will have no obligation or liability whatsoever to maintain the Plan
for any given length of time and may discontinue contributions under the Plan or
terminate the Plan at any time by written notice delivered to the Trustee and
Co-Trustees without liability whatsoever for any such discontinuance or
termination.  

     10.3.     DISTRIBUTIONS UPON TERMINATION OF THE PLAN.  Upon termination of
the Plan by the Corporation, the Trustee will distribute to each Participant (or
other person entitled to distribution) the value of the Participant's Accounts
determined as of the Valuation Date coinciding with or next following the date
of the Plan's termination.  However, if a successor Plan is established within
the meaning of Code section 401(k)(2)(B)(i)(II), Accounts shall be distributed
to Participants and their Beneficiaries only in accordance with Article 6
relating to in-service withdrawals and upon the actual separation from service
by the Participant.

                                      29


     10.4.     MERGER OR CONSOLIDATION OF PLAN; TRANSFER OF PLAN ASSETS.  In
case of any merger or consolidation of the Plan with, or transfer of assets and
liabilities of the Plan to, any other Plan, provision must be made so that each
Participant would, if the Plan then terminated, receive a benefit immediately
after the merger, consolidation or transfer which is equal to or greater than
the benefit he or she would have been entitled to receive immediately before the
merger, consolidation or transfer if the Plan had then terminated.


                         ARTICLE 11.  LIMITS ON CONTRIBUTIONS
                                           
     11.1.     CODE SECTION 404 LIMITS.  The sum of the contributions made by
the Employers under the Plan for any Plan Year shall not exceed the maximum
amount deductible under the applicable provisions of the Code (all such
contributions being hereby conditioned on their deductibility under Code section
404).  

     11.2.     CODE SECTION 415 LIMITS.  

          (a)  The "annual addition" (within the meaning of Code section
     415(c)(2) and the Regulations thereunder) to a Participant's Accounts under
     the Plan for any limitation year, when added to the annual additions to his
     or her accounts for such limitation year (as defined below) under all other
     defined contribution plans maintained by the Corporation, all other
     Affiliated Corporations and all Subsidiaries, shall not exceed the lesser
     of (i) $30,000 (or, if greater, one-fourth of the limitation in effect for
     the limitation year under Code section 415(b)(1)(A)), or (ii) 25 percent of
     the Participant's Compensation for such limitation year.  In the case of a
     Participant who also participates in a defined benefit Plan maintained by
     the Corporation, any Affiliated Corporation or any Subsidiary, the annual
     addition for a limitation year will, if necessary, be further limited so
     that the sum of the Participant's "defined contribution fraction" (as
     determined under Code section 415(e) and the regulations thereunder,
     including any special transition rules) and his or her "defined benefit
     plan fraction" (as determined under Code section 415(e) and the regulations
     thereunder) for such limitation year does not exceed 1.0.  For purposes of
     determining the Code section 415 limits under the Plan, the "limitation
     year" shall be the calendar year.  For purposes of this Article 11, the
     term "Subsidiary" shall mean any corporation, partnership, joint venture or
     business trust, more than fifty percent (50%) of which is owned, directly
     or indirectly, by the Corporation.

          (b)  To the extent necessary to satisfy the limitations of Code
     section 415 for any Participant, the annual addition which would otherwise
     be made on behalf of the Participant under the Plan shall be reduced only
     after the Participant's benefit is reduced under any and all qualified
     defined benefit plans, and after the Participant's annual addition is
     reduced under any other defined contribution plan.  The Participant's
     annual addition under this Plan shall be reduced, by reducing and refunding
     to Participant, first, his or her Supplemental After-Tax Contributions,
     then his or her Supplemental Pre-Tax Contributions, then his or her Basic
     After-Tax Contributions, and then his or her Basic Pre-Tax Contributions
     for the limitation year.  Any After-Tax Contribution that is refunded will
     be adjusted for income or loss pursuant to Regulation section 1.401(m)-1(e)
     (3)(ii) and any Pre-Tax 

                                      30


     Contribution that is refunded will be adjusted for income or loss 
     pursuant to Regulation section 1.401(l)-1(f)(4)(ii).  Any Employer 
     Contribution based upon such Basic After-Tax Contributions or Basic 
     Pre-Tax Contributions shall also be reduced, and the amount by which the 
     Employer Contribution is reduced will remain part of the assets of the 
     Trust and allocated to the  Participants' Employer Contribution Accounts 
     in the following year at the same time and in the same manner as 
     Employer Contributions are allocated under Section 3.5.  If further 
     adjustments are required, any Qualified Nonelective Employer 
     Contribution for the Participants' benefit shall be reduced and the 
     amount by which it is reduced will remain part of the Trust and 
     allocated to the Participants' Employer Contribution Accounts in the 
     following year at the same time and in the same manner as Employer 
     Contributions are allocated under Section 3.5.

          (c)  If, as the result of a reasonable error in estimating a
     Participant's Compensation for a Plan Year or limitation year or under such
     other facts and circumstances as may be permitted under regulation or by
     the Internal Revenue Service, the annual addition under the Plan for a
     Participant would cause the Code section 415 limitations for a limitation
     year to be exceeded, the excess amounts in the Participant's Accounts will
     be used to reduce Employer Contributions for the next limitation year (and
     succeeding limitation years, as necessary) for that Participant if such
     Participant is covered by the Plan as of the end of the limitation year. 
     However, if the Participant is not covered by the Plan as of the end of the
     limitation year, the excess amounts will not be distributed to Participants
     or former Participants, but will be held unallocated for that limitation
     year in a suspense account.  If the suspense account is in existence at any
     time during any subsequent limitation year, all amounts in the suspense
     account will be allocated to the Accounts of all Participants in proportion
     to their relative earnings and service points (as determined under Section
     3.5 above) for the subsequent limitation year, before any other
     contributions which would be part of an annual addition are made to the
     Plan for the subsequent limitation year.  No investment gains or losses
     will be allocated to any suspense account described in this paragraph.

     11.3.     CODE SECTION 402(g) LIMITS.

          (a)  IN GENERAL.  The maximum amount of Pre-Tax Contributions made on
     behalf of any Participant for any calendar year, when added to the amount
     of elective deferrals (within the meaning of Code section 402(g)(3)) under
     all other plans, contracts and arrangements of the Corporation, all
     Affiliated Corporations and all Subsidiaries with respect to the
     Participant for the calendar year, shall in no event exceed the maximum
     applicable limit in effect for the calendar year under Code section
     402(g)(1).

          (b)  DISTRIBUTION OF EXCESS DEFERRALS.  In the event that an amount is
     included in a Participant's gross income for a taxable year as a result of
     an excess deferral under Code section 402(g), and the Participant notifies
     the Administrator on or before the March 1 following the taxable year that
     all or a specified part of a Pre-Tax Contribution made or to be made for
     his or her benefit represents an excess deferral, the Administrator shall
     make every reasonable effort to cause such excess deferral, adjusted for
     allocable income or loss in accordance with Regulation section
     1.402(g)-1(d)(5), to be distributed to the Participant no later than the
     April 15 

                                      31


     following the calendar year in which such excess deferral was
     made.  No distribution of an excess deferral shall be made during the
     taxable year in which the excess deferral was made unless the correcting
     distribution is made after the date on which the Plan received the excess
     deferral and both the Participant and the Plan designate the distribution
     as a distribution of an excess deferral.  The amount of any excess
     deferrals that may be distributed to a Participant for a taxable year shall
     be reduced by the amount of Pre-Tax Contributions that were excess
     contributions and were previously distributed to the Participant for the
     Plan Year beginning with or within such taxable year.

     11.4.     CODE SECTION 401(k)(3) LIMITS.

          (a)  ACTUAL DEFERRAL RATIOS.  For each Plan Year, the Administrator
     will determine the "actual deferral ratio" for each Participant who is
     eligible for Pre-Tax Contributions.  The actual deferral ratio shall be the
     ratio, calculated to the nearest one-hundredth of one percent, of the
     Pre-Tax Contributions made on behalf of the Participant for the Plan Year
     to the Participant's Compensation for the applicable period.  For purposes
     of determining a Participant's actual deferral ratio,

               (i)  Pre-Tax Contributions will be taken into account only to the
          extent permitted by Regulation section 1.401(k)-1(b)(6) and to the
          extent required by Regulation section 1.402(g)-1(d)(1);

               (ii)  If an eligible Highly Compensated Employee is subject to
          the family aggregation rules of Code section 414(q)(6) because such
          Employee is either a five percent owner or one of the ten most highly
          paid employees, the family group shall be treated as a single Highly
          Compensated Employee with an actual deferral ratio determined by
          combining the Pre-Tax Contributions (and any amounts treated as
          Pre-Tax Contributions) and Compensation of all the eligible family
          members.

               (iii)  The applicable period for each Participant for a given
          Plan Year shall be that portion of the 12-month period ending on the
          last day of such Plan Year during which the individual was a
          Participant. 

               (iv)  Employer Contributions may be treated as Pre-Tax
          Contributions to the extent permitted by Regulation section
          1.401(k)-1(b)(3).

          (b)  ACTUAL DEFERRAL PERCENTAGES.  The actual deferral ratios for all
     Highly Compensated Employees who are eligible for Pre-Tax Contributions for
     a Plan Year shall be averaged to determine the actual deferral percentage
     for the highly compensated group for the Plan Year, and the actual deferral
     ratios for all Employees who are not Highly Compensated Employees but who
     are eligible for Pre-Tax Contributions for the Plan Year shall be averaged
     to determine the actual deferral percentage for the nonhighly compensated
     group for the Plan Year.  The actual deferral percentages for any Plan Year
     must satisfy at least one of the following tests, which shall be
     interpreted and applied by the Administrator in a manner consistent with
     Regulation section 1.401(k)-1:

                                      32


               (i)  The actual deferral percentage for the highly compensated
          group does not exceed 125 percent of the actual deferral percentage
          for the nonhighly compensated group; or

               (ii)  The excess of the actual deferral percentage for the highly
          compensated group over the actual deferral percentage for the
          nonhighly compensated group does not exceed two percentage points, and
          the actual deferral percentage for the highly compensated group does
          not exceed twice the actual deferral percentage of the nonhighly
          compensated group.

     If the actual deferral percentages for any Plan Year fail to satisfy the
     tests in (i) or (ii) above, the Administrator may, to the extent permitted
     by Regulations and for the sole purpose of satisfying those tests, treat
     the Plan as two Plans, each covering one or more classifications of
     employees (consistent with Code section 410(b) and any regulations
     thereunder).  The Administrator will then apply the foregoing tests
     separately to each such Plan.

          (c)  ADJUSTMENTS BY ADMINISTRATOR.  If, prior to the time all Pre-Tax
     Contributions for a Plan Year have been contributed to the Trust, the
     Administrator determines that Pre-Tax Contributions are being made at a
     rate which will cause the Code section 401(k)(3) limits to be exceeded for
     the Plan Year, the Administrator may, in its sole discretion, limit the
     amount of Pre-Tax Contributions to be made with respect to one or more
     Highly Compensated Employees for the balance of the Plan Year by suspending
     or reducing Pre-Tax Contribution elections to the extent the Administrator
     deems appropriate.  Any Pre-Tax Contributions which would otherwise be made
     to the Trust shall instead be paid in cash to the affected Participant.

          (d)  EXCESS CONTRIBUTIONS.  If the Code section 401(k)(3) limits have
     been exceeded for a Plan Year after all contributions for the Plan Year
     have been made, the Administrator shall determine the amount of excess
     contributions with respect to Participants who are Highly Compensated
     Employees.  To do so, the Administrator shall reduce the actual deferral
     ratio of the Highly Compensated Employee with the highest actual deferral
     ratio to the extent necessary to (i) enable the Plan to satisfy the
     401(k)(3) limits or (ii) cause such Employee's actual deferral ratio to
     equal the actual deferral ratio of the Highly Compensated Employee with the
     next highest actual deferral ratio, and shall repeat this process until the
     Plan no longer exceeds the Code section 401(k)(3) limits.  The amount of
     excess contributions for each Highly Compensated Employee for the Plan Year
     shall equal the amount of Pre-Tax Contributions (plus Employer
     Contributions which are treated as Pre-Tax Contributions for purposes of
     the Code section 401(k)(3) limits) actually made to the Trust for the Plan
     Year, less the product of the (i) the Highly Compensated Employee's reduced
     actual deferral ratio as determined under the preceding sentence, and (ii)
     his or her Compensation.  Any excess contributions will be recharacterized
     as After-Tax Contributions or distributed as provided below.  In no event
     will excess contributions remain unallocated or be allocated to a suspense
     account for allocation in a future Plan Year.

                                      33



          (e)  RECHARACTERIZATION OF EXCESS CONTRIBUTIONS.  At the option of the
     Administrator, a Participant's excess contributions may be recharacterized
     as After-Tax Contributions, provided the Administrator complies with the
     reporting requirements of Treas. Reg. section 1.40l(k)-l(f)(3) for such
     contributions and such recharacterization occurs no later than the March 15
     following the Plan Year for which the contributions were made.    

          (f)  DISTRIBUTION OF EXCESS CONTRIBUTIONS.  At the option of the
     Administrator, a Participant's excess contributions, adjusted for income or
     loss pursuant to Regulation section 1.401(k)-1(f)(4)(ii), will be
     designated by the Corporation as a distribution of excess contributions and
     distributed to the Participant.  Distribution of excess contributions will
     be made after the close of the Plan Year to which the contributions relate,
     but within 12 months after the close of such Plan Year.  

          (g)  SPECIAL RULES.  For purposes of distributing excess
     contributions,

               (i)  the amount of excess contributions that may be distributed
          with respect to a Highly Compensated Employee for a Plan Year shall be
          reduced by the amount of excess deferrals previously distributed to
          the Highly Compensated Employee for his or her taxable year ending
          with or within such Plan Year.

               (ii)  Any distribution of less than the entire amount of excess
          contributions with respect to a Highly Compensated Employee shall be
          treated as a pro rata distribution of excess contributions and
          allocable income or loss.

               (iii)  The determination and correction of excess contributions
          with respect to a Highly Compensated Employee whose actual deferral
          ratio is determined pursuant to the family aggregation rules will be
          accomplished pursuant to Regulation section 1.401(k)-1(f)(5)(iii).

          (h)  RECORDKEEPING REQUIREMENT.  The Administrator, on behalf of the
     Corporation, shall maintain such records as are necessary to demonstrate
     compliance with the Code section 401(k)(3) limits including the extent to
     which qualified matching contributions and Qualified Nonelective Employer
     Contributions are taken into account in determining the actual deferral
     ratios.

          (i)  SEPARATE APPLICATION OF LIMITS.  The limits described in this
     Section 11.4 shall be applied separately with respect to Participants
     employed by any Employer which is not an Affiliated Corporation as if such
     Participants were participants in a separate plan for purposes of Code
     section 401(k).

     11.5.     CODE SECTION 401(m) LIMITS.

          (a)  ACTUAL CONTRIBUTION RATIOS.  For each Plan Year, the
     Administrator will determine the "actual contribution ratio" for each
     Participant who is eligible for Employer Contributions.  The actual
     contribution ratio shall be the ratio, calculated to the nearest
     one-hundredth of one percent, of the Employer Contributions and After-Tax
     Contributions (if any) made on behalf of the Participant for the Plan Year,
     to the Participant's Compensation for the Plan Year.  For purposes of
     determining a Participant's actual contribution ratio,

                                      34


               (i)  Employer Contributions will be taken into account only to
          the extent permitted by Regulation section 1.401(m)-1(b)(5); 

               (ii)  If an eligible Highly Compensated Employee is subject to
          the family aggregation rules of Code section 414(q)(6) because such
          Employee is either a five percent owner or one of the ten most highly
          paid employees, the family group shall be treated as a single Highly
          Compensated Employee with an actual contribution ratio determined by
          combining the Employer Contributions, After-Tax Contributions,
          Compensation, and any amounts treated as Employer Contributions of all
          the eligible family members.

               (iii)  The applicable period for each Participant for a given
          Plan Year shall be that portion of the 12-month period ending on the
          last day of such Plan Year during which the individual was a
          Participant.

               (iv)  Pre-Tax Contributions may be treated as matching
          contributions to the extent permitted by Regulation section
          1.401(m)-1(b)(2).  Any forfeitures which are applied against Employer
          Contributions shall be treated as Employer Contributions.

          (b)  ACTUAL CONTRIBUTION PERCENTAGES.  The actual contribution ratios
     for all Highly Compensated Employees who are eligible for Employer
     Contributions and After-Tax Contributions for a Plan Year shall be averaged
     to determine the actual contribution percentage for the highly compensated
     group for the Plan Year, and the actual contribution ratios for all
     Employees who are not Highly Compensated Employees but who are eligible for
     Employer Contributions and After-Tax Contributions for the Plan Year shall
     be averaged to determine the actual contribution percentage for the
     nonhighly compensated group for the Plan Year.  The actual contribution
     percentages for any Plan Year must satisfy at least one of the following
     tests, which shall be interpreted and applied by the Administrator in a
     manner consistent with Regulation sections 1.401(m)-1 and 1.401(m)-2:

               (i)  The actual contribution percentage for the highly
          compensated group does not exceed 125 percent of the actual
          contribution percentage for the nonhighly compensated group; or

               (ii)  The excess of the actual contribution percentage for the
          highly compensated group over the actual contribution percentage for
          the nonhighly compensated group does not exceed two percentage points,
          and the actual contribution percentage for the highly compensated
          group does not exceed twice the actual contribution percentage of the
          nonhighly compensated group.

     If the actual contribution percentages for any Plan Year fail to satisfy
     the tests in (i) or (ii) above, the Administrator may, to the extent
     permitted by Regulations and for the sole purpose of satisfying those
     tests, treat the Plan as two Plans, each covering one or more
     classifications of employees (consistent with Code section 410(b) and any
     regulations thereunder).  The Administrator will then apply the foregoing
     tests separately to each such Plan.

                                      35


          (c)  MULTIPLE USE TEST.  In the event that the sum of the actual
     deferral percentage and the actual contribution percentage of the highly
     compensated group exceeds the "aggregate limit" within the meaning of
     Regulation section 1.401(m)-2(b)(3), the Administrator shall reduce such
     percentages to the extent required by such section and in a manner
     consistent with the provisions of this Plan.

          (d)  EXCESS AGGREGATE CONTRIBUTIONS.  If the limits of Code section
     401(m) have been exceeded for a Plan Year after all contributions for the
     Plan Year have been made, the Administrator shall determine the amount of
     excess aggregate contributions with respect to Participants who are Highly
     Compensated Employees.  To do so, the Administrator shall reduce the actual
     contribution ratio of the Highly Compensated Employee with the highest
     actual contribution ratio to the extent necessary to (i) enable the Plan to
     satisfy the 401(m) limits or (ii) cause such employee's actual contribution
     ratio to equal the actual contribution ratio of the Highly Compensated
     Employee with the next highest actual contribution ratio, and shall repeat
     this process until the Plan no longer exceeds the Code section 401(m)
     limits.  The amount of excess aggregate contributions for each Highly
     Compensated Employee for the Plan Year shall equal the amount of Employer
     Contributions and After-Tax Contributions (plus Pre-Tax Contributions which
     are treated as Employer Contributions for purposes of the Code section
     401(m) limits) actually made to the Trust for the Plan Year, less the
     product of the (i) the Highly Compensated Employee's reduced actual
     contribution ratio as determined under the preceding sentence, and (ii) his
     or her Compensation.  Any excess aggregate contributions will be
     distributed as provided below.  In no event will excess aggregate
     contributions remain unallocated or be allocated to a suspense account for
     allocation in a future Plan Year.

          (e)  DISTRIBUTION OF EXCESS AGGREGATE CONTRIBUTIONS.  A Participant's
     excess aggregate contributions, adjusted for income or loss pursuant to
     Regulation section 1.401(m)-1(e)(3)(ii), will be designated by the
     Corporation as a distribution of excess aggregate contributions, and
     distributed to the Participant.  Distribution of excess aggregate
     contributions will be made after the close of the Plan Year to which the
     contributions relate, but within 12 months after the close of such Plan
     Year.  The determination and distribution of excess aggregate contributions
     with respect to a Highly Compensated Employee whose actual contribution
     ratio is determined pursuant to the family aggregation rules will be
     accomplished pursuant to Regulation section 1.401(m)-1(e)(4)(iii).  

          (f)  RECORDKEEPING REQUIREMENT.  The Administrator, on behalf of the
     Corporation, shall maintain such records as are necessary to demonstrate
     compliance with the Code section 401(m) limits, including the extent to
     which qualified elective contributions and qualified nonelective
     contributions are taken into account in determining the actual contribution
     ratios.

          (g)  SEPARATE APPLICATION OF LIMITS.  The limits of this Section 11.5
     shall be applied separately with respect to Participants employed by any
     Employer which is not an Affiliated Corporation as if such Participants
     were participants in a separate plan for purposes of Code section 401(m).

                                      36




                   ARTICLE 12.  ROLLOVER AND TRANSFER CONTRIBUTIONS

     12.1.  An Eligible Employee who was formerly a participant in a plan 
described in section 401(a) of the Code and exempt from tax under section 
501(a) of the Code (the "Distributing Plan") and who has received a qualified 
total distribution prior to, January 1, 1993 (within the meaning of section 
402(a)(5)(E)(i) of the Code as in effect prior to January 1, 1993), or for 
periods after January 1, 1993, an eligible rollover (within the meaning of 
section 402(c)(4) of the Code), from the Distributing Plan (the 
"distribution") may, within 60 days of receipt of the distribution from the 
Distributing Plan, contribute to the Trust, as a "Rollover Contribution", an 
amount which

          (a)  does not exceed the fair market value of the distribution, 
     reduced by the amount contributed to the Distributing Plan on an after-tax
     basis by the Eligible Employee, as determined in accordance with section
     72(f) of the Code and the regulations thereunder, such amount to be reduced
     by any amounts theretofore distributed to the Eligible Employee which were
     not includible in his or her gross income for federal income tax purposes,
     and

          (b)   includes no property other than (i) money received in the
     distribution, and (ii) money attributable to other property received in the
     distribution which is sold and the proceeds of which are transferred
     pursuant to section 402(a)(6)(D) of the Code [after January 1, 1993,
     section 402(c)(6)].

The Eligible Employee may also transfer an eligible rollover distribution to the
Plan by way of a direct rollover which satisfies the requirements of section
401(a)(31) of the Code, and such amount shall also be considered a "Rollover
Contribution."

     12.2.     TRANSFER OF AMOUNT DISTRIBUTED FROM A ROLLOVER IRA.  An Eligible
Employee who has received a distribution from an individual retirement account
or individual retirement annuity which qualifies as a distribution described in
Code section 408(d)(3)(A)(ii) may, in accordance with such Code section and
within 60 days of receipt of the distribution from the individual retirement
account or annuity, contribute a portion of the distribution to the Trust as a
Rollover Contribution.  To qualify for transfer under this section, the value of
the individual retirement account or individual retirement annuity as the case
may be, must be attributable to a previous rollover contribution from a plan
qualified under Code section 401(a) of the Code or earnings thereon.

     12.3.     MONITORING OF ROLLOVERS.

          (a)  The Administrator shall establish such procedures and require
     such information from employees seeking to make Rollover Contributions as
     it deems necessary to insure that such Rollover Contributions satisfy the
     requirements for tax-free rollovers established by conditions of this
     Article and the Code and the Regulations.

          (b)  No amount may be contributed or transferred under this Article
     until approved by the Administrator.

     12.4.     TRANSFER CONTRIBUTION.  Subject to such restrictions and 
procedures as the Administrator may prescribe (which, without limitation, may 
include restrictions as to the type of plan from which transfers will be 
permitted), amounts held for the benefit of an 

                                      38


Eligible Employee under a Distributing Plan may be transferred (the "Transfer 
Contribution") directly by the Distributing Plan to this Plan in accordance 
with the requirements of section 414(l) of the Code and the Regulations 
thereunder.  A Transfer Contribution Account shall be established for each 
Eligible Employee for whom a Transfer Contribution is made.  To the extent 
determined by the Administrator to be required under section 411(d)(6) of the 
Code, an Eligible Employee for whom a Transfer Contribution Account is 
maintained shall be entitled to distributions and withdrawals from such 
Account under provisions not less restrictive than applied under the 
Distributing Plan.  To the extent the Distributing Plan was subject to the 
requirements of Code sections 401(a)(11) and 417, such requirements shall 
continue to apply to the transferred amount.  Transfers described in the last 
sentence of Section 12.1 shall not be allocated to a Transfer Contribution 
Account but shall be treated as Rollover Contributions for all purposes.

     12.5.     TREATMENT OF TRANSFERRED AMOUNT UNDER THE PLAN.  An individual
who makes a Rollover Contribution to the Trust or has a Transfer Contribution
made to the Trust on his or her behalf shall not be eligible to make or receive
any other contributions under the Plan until he or she has actually become a
Participant and satisfied the eligibility requirements otherwise applicable to
such contributions.  However, for all other purposes under the Plan (including
without limitation, investment directions and distributions), an individual who
makes a Rollover Contribution or for whom a Transfer Contribution has been made
shall be treated as a Participant. 

                      ARTICLE 13.  SPECIAL TOP-HEAVY PROVISIONS
                                           
     13.1.     PROVISIONS TO APPLY.  The provisions of this Article shall apply
for any top-heavy Plan notwithstanding anything to the contrary in this Plan.

     13.2.     MINIMUM CONTRIBUTION.  For any Plan Year which is a top-heavy
plan year, the Employer shall contribute to the Trust a minimum contribution on
behalf of each Participant who is not a key employee for such year and who has
not separated from service from the Corporation, all Affiliated Corporations and
all Subsidiaries by the end of the Plan Year.  The minimum contribution shall,
in general, equal 3 percent of each such Participant's Compensation received
during the Plan Year, but shall be subject to the following special rules:

          (a)  If the largest contribution on behalf of a key employee for such
     year, taking into account only Pre-Tax Contributions and Employer
     Contributions, is less than 3 percent of the key employee's Compensation
     received during the Plan Year, such lesser percentage shall be the minimum
     contribution percentage for Participants who are not key employees.  This
     special rule shall not apply, however, if this Plan is required to be
     included in an aggregation group and enables a defined benefit plan to meet
     the requirements of Code section 410(a)(4) or 410.

          (b)  No minimum contribution will be required with respect to a
     Participant for any period during which the Participant is also covered by
     another top-heavy defined contribution plan of the Corporation, an
     Affiliated Corporation or a Subsidiary which meets the vesting requirements
     of Code section 416(b) and under which the Participant receives the
     top-heavy minimum contribution.

                                      38


          (c)  No minimum contribution will be required with respect to any
     Participant who is also covered by a top-heavy defined benefit plan of the
     Corporation, an Affiliated Corporation or a Subsidiary and the Participant
     receives the top-heavy defined benefit minimum (within the meaning of Code
     section 416(c)(1) and the Regulations thereunder) under such defined
     benefit plan.

          (d)  The minimum contribution with respect to any Participant who is
     not a key employee for the particular year will be offset by any Employer
     Contributions (but not any other type of contribution) otherwise made for
     the Participant's benefit for such year.

          (e)  Any additional minimum contribution made for the benefit of a
     Participant under this Section shall be credited to his or her Employer
     Contribution Account as soon as practicable after the close of the Plan
     Year for which such contribution is made.

     13.3.     SPECIAL VESTING SCHEDULE.  Each Employee who is a Participant at
any time during a top-heavy plan year shall have a fully vested and
nonforfeitable interest in not less than the percentage of each of his or her
Accounts as set forth in the following vesting schedule, based on the
Participant's Years of Credited Service:

                 APPLICABLE
          YEARS OF CREDITED SERVICE          NONFORFEITABLE PERCENTAGE

           less than 2                                  0%
     2 but less than 3                                 20%
     3 but less than 4                                 40%
     4 but less than 5                                 60%
     5 but less than 6                                 80%
     6 or more                                        100%

     13.4.     ADJUSTMENT TO LIMITATION ON BENEFITS.  For purposes of the Code
section 415 limits, the definitions of "defined contribution plan fraction" and
"defined benefit plan fraction" contained therein shall be modified, for any
Plan Year which is a top-heavy plan year, by applying the special rule set forth
in Code section 416(h) of the Code unless (a) the Plan and each plan with which
the Plan is required to be aggregated for top-heavy purposes satisfies the
requirements of Code section 416(h)(2)(A), and (b) such Plan Year would not be a
top-heavy plan year if "90 percent" were substituted for "60 percent" in the
definition of a top-heavy plan year.

     13.5.     DEFINITIONS.  For purposes of these top-heavy provisions, the
following terms have the following meanings:

          (a)  "key employee" means a key employee described in Code section
     416(i)(l), determined on the basis of Compensation; and

          (b)  "top-heavy plan year" means a Plan Year if the sum of the account
     balances of all key employees under the Plan and each other defined
     contribution plan (as of the applicable determination date of each such
     Plan) which is aggregated with the Plan, plus the sum of the present values
     of the total accrued benefits of all 

                                      39


     key employees under each defined benefit plan (as of the applicable 
     determination date of each such plan) which is aggregated with the Plan 
     exceeds 60 percent of the sum of such amounts for all Employees 
     (including, for purposes of this paragraph (b), any person employed by 
     the Corporation, an Affiliated Corporation or a Subsidiary) and former 
     Employees (other than former key employees, but including Beneficiaries 
     of former Employees) under the Plan and all such plans.  For purposes of 
     these determinations:

               (i)  The foregoing determination will be made in accordance with
          the provisions of Code section 416 and the regulations promulgated
          thereunder, which are specifically incorporated herein by reference.

               (ii)  The term "determination date" means, with respect to the
          initial plan year of a plan, the last day of such plan year and, with
          respect to any other plan year of a plan, the last day of the
          preceding plan year of such plan.  The term "applicable determination
          date" means, with respect to the Plan, the determination date for the
          Plan Year of reference and, with respect to any other plan, the
          determination date for any plan year of such plan which falls within
          the same calendar year as the applicable determination date of the
          Plan.

               (iii)  Accrued benefits or account balances under a plan will be
          determined as of the most recent valuation date of the plan in that
          12-month period ending on the applicable determination date of the
          plan; provided, however, that in the case of a defined benefit plan
          such valuation date must be the same date as is employed for minimum
          funding purposes, and in the case of a defined contribution plan the
          value so determined will be adjusted for contributions made after the
          valuation date to the extent required by applicable Regulations.

               (iv)  If any individual has not received any compensation from
          the Corporation, an Affiliated Corporation or a Subsidiary maintaining
          a plan (other than benefits under the Plan) at any time during the
          5-year period ending on the applicable determination date with respect
          to such plan, any accrued benefit for such individual (and the account
          of such individual) under such plan shall not be taken into account.

               (v)  Each plan of the Corporation, an Affiliated Corporation or a
          Subsidiary (whether or not terminated) in which a key employee
          participates, and any other plan of the Corporation, an Affiliated
          Corporation or a Subsidiary which enables a plan referred to in the
          preceding clause to satisfy the requirements of Code sections
          401(a)(4) and 410, shall be aggregated with the plan.  Any plan of the
          Corporation, an Affiliated Corporation or a Subsidiary not required to
          be aggregated with the Plan may nevertheless, at the discretion of the
          Administrator, be aggregated with the Plan if the benefits and
          coverage of all aggregate plans would continue to satisfy the
          requirements of sections 401(a)(4) and 410 of the Code.

                                      40


               (vi)  The determination of the present value of accrued benefits
          under a defined benefit plan shall be made on the basis of the funding
          assumptions employed by such plan.

     13.6.     SEPARATE TOP HEAVY DETERMINATIONS FOR SUBSIDIARIES.  To the
extent required by section 416 of the Code, the portion of the Plan attributable
to Participants who are employed by any Subsidiary which is not an Affiliated
Corporation shall be treated as a separate plan for purposes of the top heavy
determination and contribution requirements of this Article.

Domestic Relations Orders, and the return of contributions upon
nondeductibility, mistake of fact, or the failure of the Plan to qualify
initially.

     14.2.     LIMITATION OF RIGHTS.  Neither the establishment of the Plan or
the Trust, nor any amendment thereof, nor the creation of any fund or account,
nor the payment of any benefits, will be construed as giving to any Participant
or other person any legal or equitable right against the Corporation, any
Affiliated Corporation, any Subsidiary, the Administrator, the Trustee, or the
Co-Trustees except as provided herein, and in no event will the terms of
employment or service of any Participant be modified or in any way be affected
hereby.  It is a condition of the Plan, and each Participant expressly agrees by
his or her participation herein, that each Participant will look solely to the
assets held in the Trust for the payment of any benefit to which he or she is
entitled under the Plan.

     14.3.     NONALIENABILITY OF BENEFITS.  The benefits provided hereunder
will not be subject to alienation, assignment, garnishment, attachment,
execution or levy of any kind, and any attempt to cause such benefits to be so
subjected will not be recognized, except to the extent as may be required by
law; provided, however, that if the Administrator receives any Qualified
Domestic Relations Order that requires the payment of benefits hereunder or the
segregation of any Account, such benefits shall be paid, and such Account
segregated, in accordance with the applicable requirements of such Qualified
Domestic Relations Order.

     14.4.     CHANGES IN VESTING SCHEDULE.  A Plan amendment which changes a
vesting schedule under the Plan shall apply with respect to any Participant who
has completed three Years of Service prior to the expiration of the period
described below only to the extent that the Participant's vested percentage in
his or her Accounts determined under the amendment is greater than the
nonforfeitable percentage of his or her Accounts determined without regard to
the amendment.  The period referred to in the preceding sentence will begin on
the date the amendment of the vesting schedule is adopted and will end 60 days
after the latest of the following dates:

          (a)  the date on which such amendment is adopted;

          (b)  the date on which such amendment becomes effective; and

                                      41

     such amendment by the Administrator.

Limitation is exceeded, then the Limitation shall be prorated among the affected
individuals in proportion to each such individual's Compensation as determined

     Whereas, effective January 1, 1996, a separate plan ("PR-SRP") was
established for employees employed by an Employer located in Puerto Rico and
such employees are no longer eligible to make contributions to the Plan nor to
have contributions made to the Plan for their benefit by the Employer.  It is
intended that subsequent to the receipt by the Employer of a favorable ruling
from the Internal Revenue Service on the taxation of the transfer of funds from
the Plan to the PR-SRP, the Trustee shall transfer the then value of the
Accounts of the following Participants to the PR-SRP:  (a) any Participant who
is then eligible to participate in the PR-SRP, (b) any Participant who would
have been eligible for the PR-SRP but for the fact that he or she had terminated
employment or retired, for whom any Accounts are maintained in the Plan as of
the date of the transfer (the "Transfer Date"), and (c) any Beneficiary of a
deceased or retired Participant if such Participant would have been eligible to
participate in the PR-SRP but for his or her death prior to the transfer date,
for which Beneficiary any Accounts are maintained in the Plan as of the Transfer
Date.  For purposes of this Appendix A, any such Participant or Beneficiary
referred to in the prior sentence shall be referred to as a "Puerto Rican
Participant" and collectively as "Puerto Rican Participants".

     Effective January 1, 1996 and at all times prior to the Transfer Date, a
Puerto Rican Participant described in the prior paragraph and for whom any
Accounts are maintained in the Plan at the relevant time shall have the
following rights under the Plan:

      1.  Effective January 1, 1996, no Puerto Rican Participant shall be
          eligible under Section 2.1 for active participation for purposes of
          having contributions made to the Plan on his or her behalf.

      2.  Each Puerto Rican Participant shall remain a Participant in the Plan
          in accordance with Section 2.4 as long as any Accounts are maintained
          in the Plan for his or her benefit.

      3.  The Administrator may impose the securities law restrictions described
          in Section 2.7(a) with respect to the Accounts of any Puerto Rican
          Participant for whom such restrictions are applicable.

      4.  No contributions to the Plan under Sections 3.1-3.6 shall be permitted
          after December 31, 1995 with respect to a Puerto Rican Participant.

      5.  The Accounts of a Puerto Rican Participant shall continue to be
          adjusted in accordance with Section 4.2 as long as the Accounts are
          maintained in the Plan.

      6.  Except as provided in the following sentence, a Puerto Rican
          Participant may invest his or her Accounts in accordance with the
          provisions of Article 5, including (to the extent otherwise
          applicable) the transfer restrictions described in Section 5.4, 5.5
          and 5.6.  Any funds in a Puerto Rican Participant's Accounts that are
          invested pursuant to Section 5.2 after December 31, 1995

                                      


          shall be invested in the Putnam Stable Value Fund (not the SRP 
          Stable Value Fund), and the transfer restrictions described in 
          Section 5.5 shall not apply to balances in a Puerto Rican 
          Participant's Accounts that are held in the Putnam Stable Value 
          Fund.  A Puerto Rican Participant may transfer funds held in his or 
          her Accounts among Company Stock, the Putnam Stable Value Fund and 
          any other Investment Fund made available within the Plan, subject 
          to the restrictions in Article 5 and this Appendix.

      7.  A Puerto Rican Participant may withdraw After-Tax Contributions and
          earnings in accordance with the provisions of Section 6.1.

      8.  The provisions in Sections 6.2 (Required Distributions After Age 
          70 1/2), 6.3 (Distributions Required by a Qualified Domestic 
          Relations Order), and 6.4 (Participant's Consent to Distribution of 
          Benefits and Direct Rollover Notice) shall continue to apply to the 
          Accounts of Puerto Rican Participants.

      9.  A Puerto Rican Participant may borrow from his or her Accounts in
          accordance with the provisions of Article 7 and this paragraph 9 and
          any repayments made prior to the Transfer Date shall be invested in
          his or her Plan Accounts in accordance with Section 7.11.  Section 7.4
          is amended for Puerto Rican Participants only to provide that only one
          loan may be outstanding at any time and each loan must be in an amount
          of not less than $500.  The maximum dollar amount of any loan that a
          Puerto Rican Participant may take under Section 7 after December 31,
          1995 and prior to the Transfer Date is $40,000.

     10.  Article 8 shall apply to a Puerto Rican Participant as if he or she
          remained an Eligible Employee until the earlier of the Transfer Date
          or the date he or she terminates employment with all Employers.

     11.  Articles 9, 10, 14, and 15 shall be construed to apply to Puerto Rican
          Participants until the Transfer Date.

     12.  Articles 11, 12, and 13 shall not apply to Puerto Rican Participants
          after December 31, 1995.

The provisions of this Appendix will no longer be effective after the Transfer
Date.

                            ARTICLE 1. INTRODUCTION

     1.1  PURPOSE.  This document amends and restates the provision of the 
Abbott Laboratories Stock Retirement Plan (Puerto Rico) (the "Plan") 
effective January 1, 1997.

          The Plan is a profit sharing plan containing a cash or deferred 
arrangement intended to qualify under sections 1165(a) and (e) of the Puerto 
Rico Internal Revenue Code of 1994 (the "PR-Code") and the trust forming a 
part thereof is intended to be exempt from taxation under PR-Code section 
1165(a) and, pursuant to section 1022(i)(1) of the Employee Retirement Income 
Security Act of 1974, under section 501(a) of the United States Internal 
Revenue Code of 1986, as amended.

          Prior to October 1, 1997, Abbott Chemicals, Inc. maintained the 
Plan and was the Plan Sponsor.  On September 30, 1997 Abbott Chemicals, Inc. 
merged with and into Abbott Health Products, Inc. with Abbott Health 
Products, Inc. being the surviving corporation.  Effective October 1, 1997, 
Abbott Health Products, Inc. is the sponsor and maintains the Plan.

     1.2  OBJECTIVE.  The Plan provides an arrangement by which employees may 
invest in stock of Abbott Laboratories ("Abbott Stock") by contributing to 
the Abbott Laboratories Stock Retirement Trust (Puerto Rico) (the "Trust") 
and by which the Corporation and its affiliates in Puerto Rico will encourage 
such investment by also making contributions to the Trust.  Basic and 
Employer Contributions received by the Trust will be applied by the Trustee 
to acquire, and hold under the trust, shares of Abbott Stock for the benefit 
of the Participants in the Plan, to the end that upon retirement or prior 
termination of employment, the Participants may receive a distribution in 
cash or in Abbott Stock pursuant to the provisions of the Plan.

                            ARTICLE 2. PARTICIPATION

     2.1  DATE OF PARTICIPATION.  Each individual who was a Participant in 
the Abbott Laboratories Stock Retirement Plan on December 31, 1995 and is an 
Eligible Employee on January 1, 1996 shall be automatically eligible to 
become a Participant in the Plan.  Each other Employee shall become a 
Participant (a) for purposes of making Supplemental Contributions, on any 
Entry Date following his or her date of hire after he or she has entered into 
a Contribution Agreement under Section 3.4, and (b) for purposes of Basic 
Contributions and Employer Contributions on an Entry Date following the day 
he or 



                                       2

she completes two Years of Credited Service and completes the applicable 
forms under Sections 2.2 and 3.4, provided in each case that he or she is an 
Eligible Employee on such Entry Date.

     2.2  ENROLLMENT OF PARTICIPANTS.  An Eligible Employee shall become a 
Participant by signing an application form furnished by the Administrator 
within 30 days after he or she receives the application, or by such other 
means as the Administrator establishes for enrollment.  Such application 
shall authorize the Participant's Employer to deduct from his or her 
Compensation (or reduce his or her Compensation by) the contributions 
required under Section 3.2 or 3.3, whichever is applicable.

     2.3  REEMPLOYMENT OF PARTICIPANT.  If an Employee's employment with the 
Corporation, an Affiliated Corporation or a Subsidiary should terminate and 
such Employee is subsequently reemployed by the Corporation, an Affiliated 
Corporation or a Subsidiary, the following shall apply:

          (A)  If The Reemployment Occurs Before The Employee Has A Break 
Year, The Period Of Credited Service To Which He Or She Was Entitled At The 
Time Of Termination Shall Be Reinstated, The Period Of His Or Her Absence 
(But Not To Exceed 12 Months) Shall Be Included In His Or Her Period Of 
Credited Service, And He Or She Will Be Reinstated As A Participant On His Or 
Her Date Of Reemployment, If The Participant Is An Eligible Employee On That 
Date.

          (B)  If An Employee Is Reemployed After A Break Year, And At The 
Time Of Termination He Or She Was Not A Participant In The Plan, Then:

               (I)  If The Employee's Years Of Credited Service To Which  He 
Or She Was Entitled At The Time Of Termination Exceeds His Or Her Number Of 
Consecutive Break Years, The Period Of Credited Service To Which He Or She 
Was Entitled At The Time Of Termination Shall Be Reinstated And He Or She 
Will Be Reinstated As A Participant On His Or Her Date Of Reemployment If He 
Or She Is Then An Eligible Employee.

               (ii)  If the Employee's number of consecutive Break Years 
equals or exceeds the Period of Credited Service to which he or she was 
entitled at the time of termination, the Employee shall be considered as a 
new Employee for all purposes of the Plan and any Period of Credited Service 
to which he or she was entitled prior to the date of termination shall be 
disregarded.

          (c)  If an Employee is reemployed after a Break Year, and at the 
time of termination he or she was a Participant in the Plan, the Period of 
Credited Service to which he or she was entitled at the time of termination 
shall be reinstated.

          (d)  If a Participant is transferred or is given a leave of absence 
for a temporary or indefinite period for the purpose of becoming an employee 
of a Subsidiary or an Affiliated Corporation which is not an Employer 
hereunder, and such Participant is not treated as an Eligible Employee under 
Section 14.18, he or she will continue as a Participant until his or her 



                                       3

retirement date or earlier termination of service with the Corporation, all 
Affiliated Corporations and all Subsidiaries, except that during such period 
the Employee will make no contributions and will be credited with no Employer 
contributions except for a pro rata share of his or her Employer's 
contributions for the year in which the transfer is made or the leave began, 
as the case may be, based upon his or her own contributions and service up to 
the date of such transfer or the date such leave began, as the case may be.  
If a Participant's employment with the Corporation, all Affiliated 
Corporations and all Subsidiaries is terminated by reason of his or her 
death, retirement or otherwise while he or she is employed by the 
Corporation, any Affiliated Corporation or any Subsidiary which is not an 
Employer hereunder, the Participant will be considered to have terminated his 
or her employment with the Employers at the same time and for the same reason.

          (e)  In the case of maternity or paternity absence (as defined 
below), an Employee shall be deemed to be employed by the Corporation, an 
Affiliated Corporation, or any Subsidiary (solely for purposes of determining 
whether the Employee has incurred a Break Year) during the calendar year 
following the calendar year in which his or her employment terminated.  A 
"maternity or paternity absence" means an Employee's absence from work 
because of the pregnancy of the Employee or birth of a child of the Employee, 
the placement of a child with the Employee in connection with the adoption of 
such child  by the Employee, or for purposes of caring for the child 
immediately following such birth or placement.  The Administrator may require 
the Employee to furnish such information as the Administrator considers 
necessary to establish that the employee's absence was for one of the reasons 
specified above.

     2.4  DURATION OF PARTICIPATION.  An individual who has become a 
Participant under the Plan will remain a Participant for as long as an 
Account is maintained under the Plan for his or her benefit, or until his or 
her death, if earlier. Notwithstanding the preceding sentence and unless 
otherwise expressly provided for under the Plan, no contributions under the 
Plan shall be made on behalf of any Participant, unless the Participant is an 
Eligible Employee at the time for which the contribution or allocation is 
made.

     2.5  PARTICIPANT RESTRICTED DUE TO CONFLICT OF INTEREST.   If a conflict 
of interest as defined in subsection (d) should arise with respect to any 
Participant:

          (a)  Such Participant shall continue as a Participant until his or 
her retirement date or earlier termination of service with the Employer, an 
Affiliated Corporation or a Subsidiary, except that during the period of such 
conflict of interest such Participant shall make no Basic After-Tax 
Contributions, such Participant's Employer shall make no Basic Pre-Tax 
Contributions on his or her behalf, and such Participant shall be credited 
with no Employer Contributions except for a pro rata share of his or her 
Employer's Employer Contributions for the year in which such conflict arises, 
based on his or her Basic Contributions and service to the date such conflict 
arises.

          (b)  Such Participant must, within 30 days after notice from the 
Administrator, elect to have 100% of the value of the shares of Abbott Stock 
credited to his or her Accounts transferred to the Putnam Stable Value Fund 
or one of the other investment options available under the 



                                       4

Plan (other than Abbott Stock).  If the Participant fails to make such 
election, the value of such shares will be fixed at the closing price of 
common shares of the Company on the 30th day after such notice from the 
Administrator (or the next preceding business day for which there is a sale 
of Abbott Stock if there are no sales on such date) as reported by the New 
York Stock Exchange Composite Reporting System, and transferred to the 
default Investment Fund selected under Section 5.6.  Any Basic After-Tax 
Contributions, Basic Pre-Tax Contributions and pro-rata Employer 
Contributions, any Supplemental After-Tax Contributions and Supplemental 
Pre-Tax Contributions designated by the Participant under Section 5.1 to be 
invested in shares of Abbott Stock, and any dividends on shares of Abbott 
Stock held in the Participant's Accounts, made for or paid during the 
calendar year in which such conflict of interest arises, shall likewise be 
transferred to the investment option the Participant selects under the first 
sentence of this subsection (b) or to the default Investment Fund referred to 
in the second sentence.  These transfers shall not be subject to any of the 
investment restrictions described in Section 5.4.

          (c)  Such Participant may elect to make Supplemental After-Tax 
Contributions and Supplemental Pre-Tax Contributions during the period of 
such conflict of interest, notwithstanding the suspension of Basic After-Tax 
Contributions and Basic Pre-Tax Contributions under subsection (a), provided 
that no such contributions may be invested in shares of Abbott Stock.

          (d)  A "conflict of interest" means a business, professional, 
family or other relationship involving the Participant which, as a result of 
statute, ordinance, regulation or generally recognized professional standard 
or rule requires divestiture by the Participant of shares of Abbott Stock.  
The existence or non-existence of a conflict of interest for purposes of this 
Section 2.5 shall be determined by the Administrator, which determination 
shall be final and binding on all persons.  Any determination made under this 
subsection (d) shall have no effect on the application of any human resources 
policies of any Employer regarding conflict of interest.

     2.6  PARTICIPATION BY ADDITIONAL PARTICIPATING EMPLOYERS.  Any 
Subsidiary or Affiliated Corporation may adopt the Plan and become a 
participating Employer hereunder by: 

          (a)  filing with the Board of Directors and the Trustee a written
instrument to that effect, and

          (b)  filing with the Trustee a certified copy of a resolution of 
the Board of Directors consenting to such action. 

At the time the Plan is adopted by any Subsidiary or Affiliated Corporation 
or any time thereafter, the Board of Directors may modify the Plan or any of 
its terms as applied to said Subsidiary, or Affiliated Corporation and its 
employees.

                           ARTICLE 3.  CONTRIBUTIONS

     3.1  PARTICIPANT CONTRIBUTIONS. Except as provided in Section 2.5, each 
Participant who has satisfied the eligibility requirements of Section 2.1(b) 
may have Basic Contributions made to the Plan on his or her behalf as 
described in Section 3.2.  Each Participant who has satisfied the eligibility 
requirements of Section 2.1(a) may elect to have Supplemental Contributions 
made to the Plan on his or her behalf as described in Section 3.3 at any time 
after his or her date of hire; provided, however, that



                                       5

if the Participant is eligible to make Basic Contributions, he or she may make
Supplemental Contributions only if Basic Contributions are concurrently being
made.

     3.2  BASIC CONTRIBUTIONS.  Except as provided in Section 2.5, each 
Participant who is an Eligible Employee may enter into a Contribution 
Agreement with the Employer under which the Participant's Compensation for 
each pay period shall be reduced by 2%, and the Employer will contribute to 
the Trust an equal amount as a Basic Pre-Tax Contribution, or as a Basic 
After-Tax Contribution, as the Participant elects.  Nevertheless, if in order 
to satisfy the nondiscrimination limits provided under PR-Code Section 
1165(e)(3) a Participant's Basic Pre-Tax Contributions must be reduced or 
entirely suspended for the remainder of a Plan Year, the Participant's 
Compensation for the remainder of that Plan Year will continue to be reduced 
and contributed to the Trust as a Basic After-Tax Contribution.  For purposes 
of this Section 3.2, Compensation shall be limited to that portion of the 
Participant's Compensation as is determined from time to time by the Board of 
Directors or the Board of Review.  Each Participant who makes such 
contributions shall be eligible to share in the Employer Contributions under 
Section 3.5.

     3.3  SUPPLEMENTAL CONTRIBUTIONS.  If a Participant has made the Basic 
Contributions required under Section 3.2 (or is not yet eligible to make such 
contributions because he or she has not completed two Years of Credited 
Service), he or she may make Supplemental Contributions in an amount equal to 
an additional 1% to 8% of his or her Compensation as Supplemental Pre-Tax 
Contributions (1% to 10% of his or her compensation if he or she made Basic 
After-Tax Contributions or is not yet eligible to make Basic Contributions 
because he or she has not completed two Years of Credited Service) and an 
additional 1% to 10% of his or her Compensation as Supplemental After-Tax 
Contributions; provided that the aggregate Supplemental Contributions shall 
not exceed 16% of the Participant's Compensation, and all Supplemental 
Contributions shall be multiples of 1% of the Participant's Compensation.  
The Participant shall elect in the Contribution Agreement described in 
Section 3.4 to make such contributions either as Supplemental Pre-Tax 
Contributions or as Supplemental After-Tax Contributions, or both, as 
applicable.  No Employer Contributions under Section 3.5 shall be made with 
respect to such Supplemental Contributions.

     3.4  CONTRIBUTION AGREEMENTS.  Each Contribution Agreement shall be on a 
form prescribed or approved by the Administrator or in such manner as the 
Administrator finds acceptable, and may be entered into, changed or revoked 
by the Participant, with such prior notice as the Administrator may 



                                       6

prescribe, as of the first day of any pay period with respect to Compensation 
payable thereafter.  A Contribution Agreement shall be effective with respect 
to Compensation payable to a Participant after the date determined by the 
Administrator, but not earlier than the date the Agreement is entered into. 
The Administrator may reject, amend or revoke the Contribution Agreement of 
any Participant if the Administrator determines that the rejection, amendment 
or revocation is necessary to ensure that the limitations referred to in 
Section 3.8 and Article 11 are not exceeded.

     3.5  EMPLOYER CONTRIBUTIONS.  For each Plan Year beginning with the Plan 
Year ending December 31, 1996, the Employers shall make Employer 
Contributions to the Trust for the benefit of each Participant who is an 
Eligible Employee at any time during the Plan Year and on whose behalf Basic 
Contributions have been made at any time during the Plan Year.  The amount of 
Employer Contributions made by the Employers for the Plan Year shall be the 
amount allocated under Section 1.4 of the Preamble to the Abbott Laboratories 
Stock Retirement Program.

          The Employers shall contribute quarterly to the Unallocated Account 
one-quarter of the estimated Employer Contributions for the Plan Year.  The 
Trustee shall invest such funds in Abbott Stock periodically in accordance 
with stock trading procedures established by the Committee and agreed to by 
the Trustee.  All dividends paid during the year on the Abbott Stock thus 
purchased and held in the Unallocated Account and other income received on 
Employer Contributions held in the Unallocated Account pending investment in 
Abbott Stock shall be used to purchase additional Abbott Stock to the extent 
such funds are not used to pay Plan expenses.

         After the amount of Employer Contributions for the Plan Year has 
been determined, the Employers shall pay the remaining Employer Contributions 
to the Trust within 90 days after the end of the Plan Year.  The Abbott Stock 
purchased with such additional Employer Contributions and all shares of 
Abbott Stock then held in the Unallocated Account shall be allocated among 
the accounts of the eligible Participants as of the last day of the Plan 
Year, based on the value of the Participant's earnings points and service 
points determined as follows:



                                       7

     (a)  One earnings point will be allocated to each eligible Participant 
for each $2 of Basic Contributions made on his or her behalf during the Plan 
Year;

     (b)  Five service points will be allocated to each eligible Participant 
for each full Year of Credited Service he or she has earned as of the end of 
the Plan Year, not to exceed 175 service points;

     (c)  A Participant who dies, retires under the Abbott Puerto Rico 
Retirement Plan, or terminates employment with an Employer on account of 
total disability for which benefits are payable under the Abbott Puerto Rico, 
Inc. Extended Disability Plan, at any time during the Plan Year, will be 
considered as having continued to be employed until December 31 of that Year 
and will thus earn a Year of Credited Service for purposes of subsection (b);

     (d)  A Participant who separates from service with the Corporation, all 
Affiliated Corporations and all Subsidiaries for any reason other than death, 
disability or retirement, at any time during the Plan Year, will be allocated 
a pro rata portion of the service points the Participant would have received 
had the Participant continued to be employed until December 31 of that Year, 
prorated based on the months during the Plan Year prior to the Participant's 
separation from service, and will thus earn a partial Year of Credited 
Service for purposes of subsection (b);

     (e)  A Participant who is transferred or given a leave of absence in 
circumstances described in Section 2.3(d) above, at any time during the Plan 
Year, will be allocated a pro rata portion of the service points the 
Participant would have received had the Participant continued until December 
31 of that year, prorated based on the Participant's service up to the date 
of such transfer or the date such leave began, as the case may be, and will 
thus earn a partial Year of Credited Service for purposes of subsection (b);

     (f)  If (i) a Participant retires under the Abbott Puerto Rico 
Retirement Plan and elects to receive the distribution of his or her Accounts 
during the same Plan Year, (ii) a Participant dies during the Plan Year and 
the Beneficiary elects to take a distribution of the Participant's Accounts 
during the same Plan Year; or (iii) a Participant separates from service 
during the Plan Year for reasons other than retirement or death and does not 
elect to defer his or her distribution to a later Plan Year, the Employer 
Contribution due in each case for the Plan Year shall be calculated using the 
Point Value determined for the prior Plan Year.  If a Participant or 
Beneficiary who becomes eligible for a distribution during the Plan Year does 
not take a distribution during the same Plan Year, as described in the prior 
sentence, the Employer Contribution which would be allocable to his or her 
Accounts shall be determined and allocated as of the end of the Plan Year 
under subsection 3.5(g) below, as if the Participant were actively employed 
as of the last day of the Plan Year, but shall be calculated as described in 
(a)-(e) above based on the service recognized therein.

     (g)  The amount of the Abbott Stock which will be allocated as of the 
end of the Plan Year to the Employer Contribution Account of each eligible 
Participant for such Plan Year shall be determined by multiplying the 
aggregate cost of the Abbott Stock held in the Unallocated Account at the end 
of the Plan Year by a fraction, the numerator of which is the sum of the 
Participant's earnings points and service points as of the end of the Plan 
Year and the denominator of which is the aggregate of all earnings points and 
all service points for all eligible Participants as of the end of such Plan 
Year (less the points attributable to Participants to whom or on whose behalf 
distributions are made during the Plan Year).  Once the portion of the 
aggregate cost which is attributable to each eligible Participant is 
determined, the 



                                       8

applicable number of shares represented by such cost shall be allocated to 
the Participant's Employer Contribution Account.  After the shares have been 
allocated, the Point Value for the Plan Year will be calculated by dividing 
the cost of the Abbott Stock allocated to a Participant's Accounts by the 
number of points credited to such Participants for the Plan Year.

     3.6  QUALIFIED NONELECTIVE EMPLOYER CONTRIBUTIONS.  The Employer, in its 
discretion, may make Qualified Nonelective Employer Contributions to the 
Trust for a Plan Year either (a) on behalf of all Participants for whom 
Pre-Tax Contributions are made for the Plan Year, or (b) on behalf of only 
those Participants for whom Pre-Tax Contributions for the Plan Year are made 
and who are not Highly Compensated Employees for the Plan Year, as the Board 
of Directors shall determine.  Such Qualified Nonelective Employer 
Contributions shall be made only if, when they are combined with all employer 
contributions to all plans referred to in Section 3.5, the aggregate employer 
contributions of the Employers for the Plan Year to all such plans do not 
exceed 7.5 percent of the declared dividends of Abbott Laboratories for the 
Plan Year.  Except as otherwise expressly provided for, any Qualified 
Nonelective Contribution Employer Contribution shall be treated as a Pre-Tax 
Contribution for all purposes under the Plan.

     3.7  TIME FOR MAKING AND CREDITING OF CONTRIBUTIONS.  Basic and 
Supplemental Pre-Tax and After-Tax Contributions will be withheld from the 
Participants' Compensation through payroll deductions and will be paid in 
cash to the Trust as soon as such contributions can reasonably be segregated 
from the general assets of the Employers, but in any event within 90 days 
after the date on which the Compensation to which such contributions relate 
is paid.  Such contributions will be credited to the Participants' respective 
Pre-Tax Contribution and After-Tax Contribution Accounts as of the earlier of 
(a) the date such contributions are received by the Trust and (b) the last 
day of the Plan Year in which the Compensation is paid.  In addition and 
subject to the limits provided in Section 3.3, a Participant may make 
Supplemental After-Tax Contributions by delivering to the Trustee, a 
certified check in the amount of such contribution and the contribution shall 
be credited to the Participant's Supplemental After-Tax Contribution Account 
as of the date it is received by the Trustee.  Any Employer Contributions or 
Qualified Nonelective Employer Contributions for a Plan Year will be 



                                       9

contributed to the Trust at such time as the Employer determines, but no 
later than the time prescribed by law (including extensions) for filing the 
Employer's federal or Puerto Rico income tax return for its taxable year in 
or with which the Plan Year ends.  Such contributions will be credited to the 
Employer Contribution Accounts or Pre-Tax Contribution Accounts, 
respectively, of Participants on whose behalf they are made at such time as 
the Corporation determines, but no later than the last day of such Plan Year.

     3.8  CERTAIN LIMITS APPLY.  All contributions to this Plan are subject 
to the applicable limits set forth under PR-Code sections 1165(e) and 
1023(n), as further described in Article 11.

     3.9  RETURN OF CONTRIBUTIONS.  No property of the Trust or contributions 
made by the Employers pursuant to the terms of the Plan shall revert to the 
Employers or be used for any purpose other than providing benefits to 
Eligible Employees or their Beneficiaries and defraying the expenses of the 
Plan and the Trust, except as follows:

          (a)  Upon request of the Corporation, contributions made to the 
Plan before the issuance of a favorable determination letter by the Puerto 
Rico Treasury Department with respect to the initial qualification of the 
Plan under section 1165(a) of the PR-Code may be returned to the contributing 
Employer, with all attributable earnings, within one year after the Puerto 
Rico Treasury Department refuses in writing to issue such a letter.

          (b)  Any amount contributed under the Plan by an Employer by a 
mistake of fact as determined by the Employer may be returned to such 
Employer upon its request, within one year after its payment to the Trust.

          (c)  Any amount contributed under the Plan by an Employer on the 
condition of its deductibility under section 1023(n) of the PR-Code may be 
returned to such Employer upon its request, within one year after the Puerto 
Rico Treasury Department disallows the deduction in writing.

          (d)  Earnings attributable to contributions returnable under 
paragraph (b) or (c) shall not be returned to the Employer, and any losses 
attributable to those contributions shall reduce the amount returned.

In no event shall the return of a contribution hereunder cause any 
Participant's Accounts to be reduced to less than they would have been had 
the mistaken or nondeductible amount not been contributed.  No return of a 
contribution hereunder shall be made more than one year after the mistaken 
payment of the contribution, or disallowance of the deduction, as the case 
may be.



                                      10


                       ARTICLE 4.  PARTICIPANT ACCOUNTS 

    4.1  ACCOUNTS.  The Administrator will establish and maintain (or cause 
the Trustee to establish and maintain) for each Participant a Basic After-Tax 
Contribution Account, a Basic Pre-Tax Contribution Account, a Supplemental 
After-Tax Contribution Account, a Supplemental Pre-Tax Contribution Account, 
an Employer Contribution Account, a Rollover Contribution Account (if 
applicable), a Transfer Contribution Account (if applicable) and such other 
accounts or sub-accounts as the Administrator in its discretion deems 
appropriate.  All such Accounts shall be referred to collectively as the 
"Accounts".

    4.2  ADJUSTMENT OF ACCOUNTS.  As of each Valuation Date, the 
Administrator or Trustee, as the case may be, shall adjust the balances of 
each Account maintained under the Plan on a uniform and consistent basis to 
reflect the contributions, distributions, income, expense, and changes in the 
fair market value of the assets attributable to such Account since the prior 
Valuation Date, in such reasonable manner as the Administrator or Trustee, as 
the case may be, shall determine.  Employer Contributions made to the 
Unallocated Account, Abbott Stock acquired under Section 3.5 with such 
Employer Contributions, and dividends paid on such Abbott Stock will not be 
valued as of each Valuation Date, but will be allocated to the Participants' 
Accounts only as of the end of the Plan Year in accordance with Section 3.5 
and thereafter such amounts will be valued in accordance with the first 
sentence of this Section 4.2.  Notwithstanding any other provision of the 
Plan, to the extent that Participants' Accounts are invested in mutual funds 
or other assets for which daily pricing is available ("Daily Pricing Media"), 
all amounts contributed to the Trust will be invested at the time of their 
actual receipt by the Daily Pricing Media, and the balance of each Account 
shall reflect the results of such daily pricing from the time of actual 
receipt until the time of distribution.  Investment elections and changes 
made pursuant to Section 5.5 shall be effective upon receipt by the Daily 
Pricing Media.




                                      11


References elsewhere in the Plan to the investment of contributions "as of" a
date other than that described in this Section 4.2 shall apply only to the
extent, if any, that assets of the Trust are not invested in Daily Pricing
Media.

                       ARTICLE 5.  INVESTMENT OF ACCOUNTS

    5.1  ABBOTT STOCK.  All Basic Contributions and Employer Contributions 
shall be invested in shares of Abbott Stock.  A Participant may also direct 
that some or all of his or her Supplemental Contributions, Rollover 
Contributions (if applicable) or Transfer Contributions (if applicable) be 
invested in shares of Abbott Stock.  Abbott Stock shall be purchased and sold 
by the Trustee on the open market or from Abbott in accordance with stock 
trading procedures established by the Committee and agreed to by the Trustee.

    5.2  PUTNAM STABLE VALUE FUND.  A Participant may direct that some or all 
of his or her Supplemental Contributions, Rollover Contributions, or Transfer 
Contributions be invested in the Putnam Stable Value Fund.

    5.3  OTHER INVESTMENT FUNDS.  The Committee may, from time to time, 
direct the Trustee to establish one or more Investment Funds.  A Participant 
may invest some or all of his or her Supplemental Contributions, Rollover 
Contributions or Transfer Contributions made on or after January 1, 1996 in 
one or more of the Investment Funds available under the Plan in such 
increments and in such manner as the Committee and the Trustee establish in 
investment procedures.  To the extent permitted by Section 5.4, a Participant 
may instruct the Trustee that amounts held in his or her Accounts that are 
invested in Abbott Stock be transferred to and invested in one or more of the 
Investment Funds established under this Section 5.3.  Any amounts held in a 
Participant's Accounts that are not otherwise restricted as to investment 
under Section 5.1 or 5.4 may be invested or reinvested in Abbott Stock or any 
of the Investment Funds then available under the Plan in accordance with the 
procedures established under Section 5.5.



                                      12


    5.4  PRE-RETIREMENT FEATURE FOR REINVESTMENT OF ABBOTT STOCK.  Effective 
April 4, 1996 (or such subsequent date as the Administrator determines in his 
or her sole discretion), and for periods thereafter, a Participant who 
attains age 50 may direct the Trustee to liquidate all or a portion of the 
Abbott Stock held in his or her Accounts and reinvest the proceeds in the 
Putnam Stable Value Fund or any of the other Investment Funds described in 
Section 5.3.

         Basic Contributions made to the Plan with respect to a Participant 
who is eligible for the Pre-Retirement Feature described in this Section 5.4 
shall continue to be invested initially in shares of Abbott Stock, but will 
be available for reinvestment under this Section 5.4.

         The restrictions described herein shall apply to the Accounts of all 
eligible active Participants, all Participants who terminate employment 
(other than those who retire under the Abbott Puerto Rico Retirement Plan), 
all Beneficiaries of Participants who died while employed or



                                      13


after termination of employment (other than Beneficiaries of Participants who 
retired under the Abbott Puerto Rico Retirement Plan) and all Alternate 
Payees to the extent the Participant, Beneficiary or Alternate Payee 
satisfies the applicable age requirements of this Section 5.4.

    5.5  INVESTMENT ELECTIONS.  Subject to Sections 5.1, 5.2, and 5.4, a 
Participant, Beneficiary or Alternate Payee may make or change investment 
instructions with respect to the portion of the Accounts over which he or she 
has investment direction at such times and at such frequency as the 
Administrator shall permit in accordance with investment procedures 
established for the Plan.  Such investment instructions shall be in writing 
or in such other form as is acceptable to the Trustee.

    5.6  DEFAULT INVESTMENT FUND.  The Administrator shall identify from time 
to time one or more of the Investment Funds as the default Investment Fund 
into which all contributions, for which the Participant has the right to 
direct investment, shall be invested if the Participant fails to provide 
complete and clear investment instructions for such contributions.  Such 
contributions shall remain in the default Investment Fund until the Trustee 
receives investment instructions from the Participant in a form acceptable to 
the Trustee.

    5.7  PARTICIPANT DIRECTION OF INVESTMENTS.  To the extent that this 
Article 5 does not prohibit a Participant, Beneficiary or Alternate Payee 
from directing the investment of his or her Accounts, the Plan is intended to 
be a participant-directed plan and to comply with the requirements of ERISA 
section 404(c) and the United States Department of Labor Regulations 
2550.404c-1 as a participant-directed plan.  To the extent this Section 5.7 
applies, the Administrator shall direct the Trustee from time to time with 
respect to such investments pursuant to the instructions of the Participant 
(or, if applicable, the Alternate Payee, or the deceased Participant's 
Beneficiary), but the Trustee may refuse to honor any investment instruction 
if such instruction would cause the Plan to engage in a prohibited 
transaction (as described in ERISA section 406) or cause the Trust to be 
subject to income tax.  The Administrator shall prescribe the form upon 
which, or such other manner in which such instructions shall be made, as well 
as the frequency with which such instructions may be made or changed and the 
dates as of which such instructions shall be effective.  The Board of 
Directors reserves the right to amend the Plan to



                                      14


remove the right of Participants, Beneficiaries or Alternate Payees to give 
investment instructions with respect to their Accounts.  Nothing contained 
herein shall provide for the voting of shares of Abbott Stock by any 
Participant, Beneficiary or Alternate Payee, except as otherwise provided in 
the Trust.

    5.8  DIVIDENDS ON ABBOTT STOCK.  Except with respect to shares of Abbott 
Stock acquired during the Plan Year and held in the Unallocated Account, cash 
dividends on shares of Abbott Stock shall be credited to the applicable 
Accounts in which the shares are held and cash proceeds from the sale of any 
rights or warrants received with respect to such Stock shall be invested in 
shares of Abbott Stock when such dividends or proceeds are received by the 
Trust, and thereafter such shares shall be credited to such Accounts based on 
the average cost of all shares purchased with such dividends or proceeds. 
Stock dividends or "split-ups" and rights or warrants appertaining to such 
shares shall be credited to the applicable Accounts when received by the 
Trust.  Cash dividends received with respect to shares of Abbott Stock held 
in the Unallocated Account and cash proceeds from the sale of rights or 
warrants received with respect to such Abbott Stock shall be reinvested in 
Abbott Stock and allocated under Section 3.5, to the extent not used to pay 
expenses of the Plan.  Any stock dividends or "split-ups" (and any rights or 
warrants unless sooner sold) appertaining to shares of Abbott Stock held in 
the Unallocated Account will be held in the Unallocated Account until the end 
of the Plan Year and allocated under Section 3.5.


           ARTICLE 6.  WITHDRAWALS PRIOR TO SEPARATION FROM SERVICE

    6.1  IN-SERVICE WITHDRAWALS OF AFTER-TAX CONTRIBUTIONS.

         (a)  SUPPLEMENTAL AFTER-TAX CONTRIBUTIONS.   A Participant may elect 
     to withdraw from the Trust any or all of his or her Supplemental After-Tax 
     Contributions.  Withdrawals shall be made from Abbott Stock, the Putnam 
     Stable Value Fund or any other Investment Fund as the Participant elects, 
     but only to the extent such total withdrawals under this subsection (a) do 
     not exceed the Participant's Supplemental After-Tax Contributions in his or
     her Supplemental After-Tax Contribution Account.

         (b)  BASIC AFTER-TAX CONTRIBUTIONS.   A Participant who has completed 
     five or more Years of Credited Service and has withdrawn all of his or her 
     Supplemental After-Tax Contributions under subsection (a)  may then elect 
     to withdraw from the Trust any or all of his or her Basic After-Tax 
     Contributions. Withdrawals shall be made from Abbott Stock, the Putnam 
     Stable Value Fund or any other Investment Fund as the Participant elects, 
     but only to the extent



                                      15


     such total withdrawals under this subsection (b) do not exceed the 
     Participant's Basic After-Tax Contributions in his or her Basic 
     After-Tax Contribution Account.

         (c)  VALUATION OF SHARES WITHDRAWN.  Withdrawals of shares of Abbott 
     Stock under this Section 6.1 from Basic and Supplemental After-Tax 
     Contribution Accounts shall be in whole shares except when withdrawal of a 
     fractional share is necessary to exhaust the Abbott Stock allocated to such
     Accounts in which event the cash value of such fractional share shall be 
     withdrawn.

         (d)  (i)  For purposes of Section 6.1(a), shares of Abbott Stock 
         purchased with a Participant's Supplemental After-Tax Contributions 
         shall be determined as follows:

                   (A)  FIRST, the average cost to the Trust of all withdrawn 
              shares of Abbott Stock purchased with the Participant's 
              Supplemental After-Tax Contributions and related dividends shall 
              be established.

                   (B)  NEXT, the total of the Participant's unwithdrawn 
              Supplemental After-Tax Contributions and applied to purchase 
              Abbott Stock shall be divided by the average cost established 
              under subparagraph (A) above and the resulting amount shall be 
              the number of shares purchased with the Participant's 
              Supplemental After-Tax Contributions.

              (ii) For purposes of Section 6.1(b), shares of Abbott Stock 
         purchased with a Participant's Basic After-Tax Contributions shall be 
         determined as follows:

                   (A)  FIRST, the average cost to the Trust of all unwithdrawn 
              shares of Abbott Stock purchased with the Participant's Basic 
              After-Tax Contributions and related dividends shall be 
              established.

                   (B)  NEXT, the total of the Participant's unwithdrawn Basic 
              After-Tax Contributions applied to purchase Abbott Stock shall be 
              divided by the average cost established under subparagraph (A) 
              above and the resulting amount shall be the number of shares 
              purchased with the Participant's Basic After-Tax Contributions.

     For purposes of determining a Participant's unwithdrawn Basic After-Tax 
     Contributions, any shares of Abbott Stock purchased with the Participant's 
     Basic After-Tax Contributions that were withdrawn by the Participant as of 
     any date shall be charged at the average cost established under 
     subparagraph (i)(A) above as of such date.

         (e)  The foregoing provisions of this Section 6.1 are subject to the
         following:

              (i)  Shares of Abbott Stock and other amounts that are withdrawn 
         by a Participant under this Section 6.1 shall be charged to his or her 
         respective After-Tax Contribution Account.



                                      16


              (ii)  No more than one withdrawal may be elected in any calendar 
         quarter; provided, however, that the Administrator, in his or her sole 
         discretion, may waive this limitation in unusual cases.

              (iii)  Distribution of the shares of Abbott Stock or other amounts
         a Participant elects to withdraw under this Section 6.1 will be made 
         within such time period and in accordance with the procedures 
         established by the Administrator and agreed to by the Trustee.  If the 
         Participant dies prior to the time distribution of such shares or 
         amounts is made, distribution shall be made to the Participant's 
         Beneficiary in the same manner as other distributions from the Trust.

              (iv)  Each request for a withdrawal shall be filed with the 
         Administrator, shall specify the dollar amount or the share amount 
         (or both) to be withdrawn, which amount shall not be less than $500, 
         and may not be revoked, amended or changed by the Participant after it 
         is filed.  The Participant shall indicate in his withdrawal request 
         whether the withdrawal is to be made in cash or in Abbott Stock.

              (v)  Any fees associated with a withdrawal will be charged to the 
         Participant's Accounts.

              (vi)  Withdrawals under this Section 6.1 shall be subject to such 
         further conditions and limitations as the Administrator may establish 
         from time to time and apply on a uniform basis.

              (vii)  Any shares of Abbott Stock that are withdrawn will be 
         considered as having been withdrawn at the average cost, as of the date
         of the withdrawal, of the shares of Abbott Stock reflected in the 
         Account from which it was withdrawn.

    6.2  DISTRIBUTIONS REQUIRED BY A QUALIFIED DOMESTIC RELATIONS ORDER.  To 
the extent required by a Qualified Domestic Relations Order, the Administrator 
shall make distributions from a Participant's Accounts to Alternate Payees 
named in such order in a manner consistent with the distribution options 
otherwise available under this Plan, regardless of whether the Participant is 
otherwise entitled to a distribution at such time under the Plan. 

    6.3  PARTICIPANT'S CONSENT TO DISTRIBUTION OF BENEFITS.  If a Participant 
receives a withdrawal under Section 6.1 or an Alternative Payee receives a 
distribution under Section 6.2, no distribution may be made unless:

         (a)  between the 30th and 90th day prior to the date distribution is 
    to be made or commence, the Administrator notifies the Participant or the 
    Alternate Payee (whichever is applicable) in writing that he or she may 
    defer distribution until age 65 and provides the Participant or the 
    Alternate Payee (whichever is applicable) with a written description of the 
    material features and (if applicable) the relative values of the forms of 
    distribution available under the Plan; and



                                      17


         (b)  the Participant consents to the distribution in writing after the 
     information described above has been provided to him or her, and files such
     consent with the Administrator. Distribution to the Participant will be 
     made or commence as soon as practicable after such consent is received by 
     the Administrator.  The Participant may waive the 30-day notice period 
     described in (a) above.

                      ARTICLE 7.  LOANS TO PARTICIPANTS

     7.1  IN GENERAL.  Upon the request of an Eligible Borrower on a form 
approved or procedure prescribed by the Administrator, and subject to the 
conditions of this Article, the Administrator shall direct the Trustee to make 
a loan from the Trust to the Eligible Borrower. For purposes of this Article, 
an "Eligible Borrower" is:

         (a)  a Participant who is an Eligible Employee; or

         (b)  a Participant who is a former Employee and is a "party in 
     interest" within the meaning of ERISA section 3(14); or

         (c)  a deceased Participant's Beneficiary who has not yet received the 
     entire vested portion of the Participant's Accounts and who is a "party in 
     interest" as described in (b) above.

    7.2  RULES AND PROCEDURES.  The Administrator shall promulgate such rules 
and procedures, not inconsistent with the express provisions of this Article, 
as it deems necessary to carry out the purposes of this Article.  All such 
rules and procedures shall be deemed a part of the Plan for purposes of the 
United States Department of Labor's Regulations section 2550.408b-1(d).

    7.3  MAXIMUM AMOUNT OF LOAN.  The following limitations shall apply in 
determining the amount of any loan to an Eligible Borrower hereunder:

         (a)  The amount of the loan, together with any other outstanding 
     indebtedness under this Plan or any other qualified retirement plan of 
     Abbott, the Corporation, any Affiliated Corporation or any Subsidiary, 
     shall not exceed $50,000 reduced by the excess of (i) the highest 
     aggregate outstanding loan balance of the Eligible Borrower from such 
     plans during the one-year period ending on the day prior to the date on 
     which the loans are made, over (ii) the Eligible Borrower's outstanding 
     loan balance from such plans immediately prior to the loan.

         (b)  The amount of the loan shall not exceed 50 percent of the Eligible
     Borrower's Accounts, determined as of the Valuation Date immediately 
     preceding the date of the loan.

         (c)  No loan may exceed the aggregate value of the Participant's Basic 
     Pre-Tax Contribution Account, Supplemental Pre-Tax Contribution Account, 
     Employer Contribution Account, Rollover Contribution Account and Transfer 
     Contribution Account (excluding any amount contributed by the Participant 
     on an after-tax basis).



                                      18

    7.4  MINIMUM AMOUNT OF LOAN; NUMBER OF LOANS; FREQUENCY OF LOANS; FEES FOR
LOANS.  The minimum amount of any single loan under the Plan shall be $500.  A
Participant may have only two loans outstanding at any time under the Plan or
under any other plan referred to in Section 3.5.  The Administrator may charge 
a loan fee and such fee may be charged to the Participant's Accounts or taken 
from the loan proceeds.

    7.5  NOTE; SECURITY; INTEREST.  Each loan shall be evidenced by a note
signed by the Eligible Borrower.  The note shall be an asset of the Trust which
is allocated to the Accounts of the Eligible Borrower, and shall for purposes 
of the Plan be deemed to have a value at any given time equal to the unpaid
principal balance of the note plus the amount of any accrued but unpaid
interest.  The note shall be secured by that portion of the Accounts 
represented by the note (not to exceed 50% of the Eligible Borrower's
vested interest in his or her Accounts determined as of the date of the loan).
The loan shall bear interest at an annual percentage interest rate to be 
determined by the Administrator.  In determining the interest rate, the 
Administrator shall take into consideration interest rates currently being 
charged by persons in the business of lending money with respect to loans 
made in similar circumstances.

    7.6  REPAYMENT.  Each loan made to an Eligible Borrower who is receiving 
regular payments of Compensation from the Employer shall be repayable by 
payroll deduction.  Loans made to other Eligible Borrowers (and, in all 
events, where payroll deduction is no longer practicable) shall be repayable 
in such manner as the Administrator may from time to time determine.  In 
each case payments shall be made not less frequently than quarterly, over a 
specified term (as determined by the Administrator) not to extend beyond the 
earlier of five years from the date of the loan or the Participant's 
anticipated retirement date, with substantially level amortization.  Where 
the loan is being applied toward the purchase or construction of a principal 
residence for the Eligible Borrower, the term for repayment shall not extend 
beyond the earlier of 15 years from the date of the loan or the 
Participant's anticipated retirement date.  An Eligible Borrower may prepay 
the full balance of an outstanding loan at any time by delivering to the 
Trustee a certified check in the amount of such




                                      19

remaining balance and any accrued but unpaid interest.  An Eligible Borrower 
may also refinance an  outstanding loan, provided that the limits under 
Section 7.3 allow the  Eligible Borrower to borrow an amount equal to, or 
greater than, the balance  due on the outstanding loan.

    7.7  REPAYMENT UPON DISTRIBUTION.  If, at the time benefits are to be
distributed (or to commence being distributed) to an Eligible Borrower with
respect to a separation from service, there remains any unpaid balance of a 
loan hereunder, such unpaid balance shall, to the extent consistent with United
States Department of Labor regulations, become immediately due and payable in
full. Such unpaid balance, together with any accrued but unpaid interest on the
loan, shall be deducted from the Eligible Borrower's Accounts, subject to the
default provisions below, before any distribution of benefits is made.  Except
as is provided in Section 7.1 or as may be required in order to comply (in a
manner consistent with continued qualification of the Plan under PR-Code 
section 1165(a)) with United States Department of Labor regulations, no loan 
shall be made to an Eligible Borrower under this Article after the Eligible 
Borrower incurs a separation from service whether or not he or she has begun 
to receive distribution of his or her Accounts.

    7.8  DEFAULT.  In the event of a default in making any payment of principal
or interest when due under the note evidencing any loan under this Article, if
such default continues for more than 90 days after written notice of the 
default by the Trustee, the unpaid principal balance of the note shall 
immediately become due and payable in full.  Such unpaid principal, together 
with any accrued but unpaid interest, shall thereupon be deducted from the 
Eligible Borrower's Accounts, subject to the further provisions of this 
Section.  The amount so deducted shall be treated as distributed to the 
Eligible Borrower and applied by the Eligible Borrower as a payment of the 
unpaid interest and principal (in that order) under the note evidencing such 
loan.  In no event shall the Administrator apply the Eligible Borrower's 
Accounts to satisfy the Eligible Borrower's repayment obligation, whether or 
not he or she is in default, unless the amount so applied otherwise could be 
distributed in accordance with the Plan.




                                       20

    7.9  NONDISCRIMINATION.  Loans shall be made available under this Article
to all Eligible Borrowers on a reasonably equivalent basis.

    7.10 SOURCE OF LOAN PROCEEDS.  The proceeds for a loan shall be drawn first
from an Eligible Borrower's  Supplemental Pre-Tax Contribution Account and then
from his or her Basic Pre-Tax Contribution Account and then from his or her
Employer Contribution Account to the extent such contributions were 
attributable to Pre-Tax Contributions, in each case drawing proportionately 
from the various investments held in such Accounts.

    7.11 REINVESTMENT OF LOAN REPAYMENTS.  Loan repayments shall be made to the
Eligible Borrower's Basic Contribution, Supplemental Contribution and Employer
Contribution Accounts from which the proceeds were drawn under Section 7.10 in
the proportion that the loan was taken from each such Account at the 
origination of the loan.  Within each such Account, the proceeds will be 
invested in accordance with the investment instructions or restrictions 
applicable at the time of each loan repayment.  If the Eligible Borrower is 
not currently making contributions to any such Account at the time of loan 
repayment, the proceeds will be invested within such Account in accordance 
with any previous instructions on file by the Participant for the investment 
of contributions in such Account, and if there are no such instructions on 
file, the proceeds will be invested in the default investment fund 
designated under Section 5.6.  The Participant may change his or her 
investment instructions in accordance with Section 5.5 for purposes of 
reinvesting the loan repayments even if he or she is not then making 
contributions to the Plan.  Loan repayments made to the Eligible Borrower's 
Supplemental Contribution Account shall, for purposes of Article 5, be 
considered to be unrestricted as to investment and may be invested in any of 
the Investment Funds then available under the Plan.  Loan repayments made to 
the Eligible Borrower's Basic Contribution and Employee Contribution 
Accounts shall be restricted until eligible for reinvestment under Section 5.4.




                                      21

                    ARTICLE 8.  BENEFITS UPON RETIREMENT, DEATH OR
                                SEPARATION FROM SERVICE

    8.1  RETIREMENT OR SEPARATION FROM SERVICE FOR REASONS OTHER THAN DEATH.  
Following a Participant's retirement or separation from the service with 
Abbott, the Corporation, all Affiliated Corporations and all Subsidiaries 
for any reason other than death, the Participant will receive the value of 
his or her Accounts in a single sum payment.  To the extent that the 
Participant's Accounts hold Abbott Stock, he or she may receive the 
distribution in whole shares of Abbott Stock and cash for any fractional share.

    8.2  TIME OF DISTRIBUTIONS.  Distribution with respect to a Participant's
separation from service (other than on account of death or retirement) normally
will be made or commence as soon as practicable after such separation.  The
Employer Contribution made on the Participant's behalf under Section 3.5 for 
the Plan Year will be based on the Point Value determined for the prior Plan 
Year and distributed to the Participant in cash.  In the case of a 
Participant whose Accounts are valued in excess of $3,500 and who has not 
yet attained age 65, however, distribution may not be made under this 
Section unless:

         (a)  between the 30th and 90th day prior to the date 
    distribution is to be made or commence, the Administrator notifies the 
    Participant in writing that he or she may defer distribution until age 65
    and provides the Participant with a written description of the material 
    features and (if applicable) the relative values of the forms of 
    distribution available under the Plan; and

         (b)  the Participant consents to the distribution in writing after the
    information described above has been provided to him or her, and files such
    consent with the Administrator. Distribution to the Participant will be 
    made or commence as soon as practicable after such consent is received by 
    the Administrator.  The Participant may waive the 30-day notice period 
    described in (a) above.

The value of a Participant's Accounts will be considered to be in excess of
$3,500 if the value of such portion exceeds such amount at the time of the
distribution in question or exceeded such amount at the time of any prior
distribution to the Participant under the Plan.   Distribution in all events
will commence no later than the 60th day after the close of the Plan Year in
which occurs the later of the Participant's separation from service or the
Participant's attainment of age 65.




                                      22

         A Participant who is eligible for retirement under the terms of the
Abbott Puerto Rico Retirement Plan will normally receive a distribution as soon
as practicable after the end of the Plan Year in which he or she retires and
following the crediting of the Employer Contribution determined under Section
3.5 for such Plan Year.  Such Participant may elect to receive the distribution
in the calendar year in which he or she retires, in which event the Employer
Contribution made on the Participant's behalf under Section 3.5 will be based 
on the Point Value determined for the prior Plan Year and distributed to the
Participant in cash.

    8.3  AMOUNT AND MANNER OF DISTRIBUTION.

         (a)  SINGLE SUM PAYMENT.  In the case of a distribution to be made in 
a single sum, the amount of such distribution shall be determined as of the
Valuation Date which immediately precedes or coincides with the date 
distribution is to be made.

         (b)  CASHOUT OF SMALL BENEFITS.  If the value of a Participant's 
Accounts is $3,500 or less, distribution shall be made to the Participant in a 
single sum payment as soon as practicable following the Participant's 
separation from service.  The amount of such distribution shall be determined 
as of the Valuation Date immediately preceding or coinciding with the date the
distribution is made.  The Participant's Accounts will not be considered to be
valued at $3,500 or less, if the value of such Accounts at the time in question
or at the time of any prior distribution to the Participant under the Plan
exceeds such amount.

    8.4  DISTRIBUTIONS AFTER A PARTICIPANT'S DEATH.

         (a)  DEATH PRIOR TO SEPARATION FROM SERVICE.  If a Participant dies 
prior to his or her separation from service with Abbott, the Corporation, all
Affiliated Corporations and all Subsidiaries, the Participant's Beneficiary 
will receive the Participant's Accounts in a single sum payment as soon as
practicable after the end of the Plan Year in which the Participant's death
occurs; provided, however, the Beneficiary may elect the distribution in the
Plan Year in which the Participant's death occurred, in which event the 
Employer Contribution made on behalf of the Participant under Section 3.5 for 
such Plan Year shall be based on the Point Value determined for the prior Plan 
Year and shall be distributed in cash.  Distribution must be made to the 
Beneficiary who is not the Participant's spouse no later than December 31 of 
the calendar year following the year of the Participant's death.  If the 
Beneficiary is the Participant's spouse, the Beneficiary may elect to defer 
receipt of the distribution of the Participant's Accounts until any date, but 
not later than the December 31 of the Plan Year in which the Participant would 
have attained age 65;

         (b)  DEATH AFTER SEPARATION FROM SERVICE.  If a Participant dies after
separation from service but before the complete distribution of his or her
Accounts has been made, the Participant's Beneficiary will receive the value of
the Participant's Accounts.  Distribution will be made in a single sum payment
as soon as practicable after the Participant's death (but no later than 
December 31 of the calendar year following the year of the Participant's 
death); provided, however, that if distribution to the Participant had begun 
following his or her separation from service in a form elected by the 
Participant, distribution will continue to be




                                      23

made to the Beneficiary at least as rapidly in such form unless the 
Beneficiary elects to receive distribution  in cash in a single sum as soon 
as practicable following the Participant's  death. Any such election must be 
made on a form approved by the Administrator  and must be received by the 
Administrator within such period following the  Participant's death as the 
Administrator may prescribe.  To the extent the  Participant's Accounts held 
Abbott Stock at the time of the proposed  distribution, the Beneficiary may 
receive the distribution in whole shares of  Abbott Stock and cash for any 
fractional share.  

         (c)  CASHOUT OF SMALL BENEFITS.  If a Participant dies and the value 
of a Participant's Accounts is $3,500 or less, distribution shall be made to 
the Beneficiary in a single payment as soon as practicable following the
Participant's death (but in no event later than the 60th day following the 
close of the Plan Year in which such separation from service occurs) or such 
later date on which the amount of the distribution can be determined by the
Administrator.  The amount of such distribution shall be determined as of the
Valuation Date immediately preceding or coinciding with the date the
distribution is made. The Participant's Accounts will not be considered to be
valued at $3,500 or less, if the value of such Accounts at the time in question
or at the time of any prior distribution to the Participant under the Plan
exceeds such amount.

    8.5  DESIGNATION OF BENEFICIARY.  Subject to the provisions of this
Section, a Participant's Beneficiary shall be the person or persons (or entity
or entities), if any, designated by the Participant from time to time on a form
or in a manner approved by the Administrator.  In the absence of an effective
Beneficiary designation, a Participant's Beneficiary shall be his or her
surviving spouse, if any, or if none, the Participant's issue, or if none, the
Participant's estate.  A non-spouse Beneficiary designation by a Participant 
who is married at the time of his or her death shall not be effective unless

         (a)  prior to the Participant's death, the Participant's surviving 
spouse consented to and acknowledged the effect of the Participant's 
designation of a specific non-spouse Beneficiary (including any class of 
Beneficiaries or any contingent Beneficiaries) in a written form approved by 
the Administrator and witnessed by a notary public or a Plan representative; or

         (b)  it is established by the Participant prior to his or her death 
(by furnishing the Administrator with a sworn statement), that the required 
consent may not be obtained because there is no spouse, because the spouse 
cannot be located, or because of such other circumstances as the Secretary of 
the Treasury may prescribe; or

         (c)  the spouse had earlier executed a general consent form 
permitting the Participant (i) to select from among certain specified persons 
without any requirement of further consent by the spouse (and the Participant 
designates a Beneficiary from the specified list), or (ii) to change his or her
Beneficiary without any requirement of further consent by the spouse.  Any such
general consent shall be on a form approved by the Administrator, and must 
acknowledge that the spouse has the right to limit consent to a specific 
Beneficiary and that the spouse voluntarily elects to relinquish such right.




                                      24

Any consent and acknowledgment by a spouse, or the establishment that the
consent and acknowledgment cannot be obtained, shall be effective only with
respect to such spouse, but shall be irrevocable once made.

                             ARTICLE 9.  ADMINISTRATION

    9.1  ADMINISTRATOR.  The Administrator will be the "administrator" of 
the Plan as defined in section 3(16)(A) of ERISA and a "named fiduciary" for 
purposes of section 402(a)(1) of ERISA with authority to control and manage 
the operation and administration of the Plan, and will be responsible for 
complying with all of the reporting and disclosure requirements of Part 1 of 
Subtitle B of Title I of ERISA.  The Administrator will not, however, have 
any authority over the investment of assets of the Trust or the selection of 
Investment Funds.

    9.2  POWERS OF ADMINISTRATOR.  The Administrator will have full power to
administer the Plan in all of its details, other than the selection of
Investment Funds, subject, however, to the requirements of ERISA.  For this
purpose the Administrator's power will include, but will not be limited to, the
following discretionary authority:

         (a)  to make and enforce such rules and regulations as the 
Administrator deems necessary or proper for the efficient administration of 
the Plan or as required to comply with applicable law;

         (b)  to interpret and enforce the Plan in accordance with the terms of
the Plan and the rules and regulations adopted under subsection (a), and to 
make factual determinations thereunder, including the discretionary power to 
determine the rights or eligibility of Employees or Participants and any 
other persons, and the amount, if any, of their benefits under the Plan, and 
to construe or interpret disputed, ambiguous, or uncertain terms;

         (c)  to compute the amounts to be distributed under the Plan, to 
determine the person or persons to whom such amounts will be distributed and 
to make equitable adjustments for mistakes or errors;

         (d)  to authorize the payment of distributions and to direct the 
Trustee to make such payments from the Trust;

         (e)  to keep such records and submit such filings, elections, 
applications, returns or other documents or forms as may be required under 
the PR-Code, ERISA and applicable regulations, or under other federal, state 
or local law and regulations;

         (f)  to allocate and delegate its ministerial duties and 
responsibilities and to appoint such agents, counsel, accountants, 
consultants, actuaries and insurance companies as may be required or desired 
to assist in administering the Plan;




                                      25

         (g)  by written instrument, to allocate and delegate his or her 
fiduciary responsibilities in accordance with ERISA section 405; and

         (h)  to furnish each Employer with such information and data as may be
required by it for tax and other purposes in connection with the Plan.

         Actions taken in good faith by the Administrator shall be binding 
and conclusive on all parties.

    9.3  NONDISCRIMINATORY EXERCISE OF AUTHORITY.  Whenever, in the
administration of the Plan, any discretionary action by the Administrator is
required, the Administrator shall exercise its authority in a nondiscriminatory
manner so that all persons similarly situated will receive substantially the
same treatment.

    9.4  RELIANCE ON TABLES, ETC.  In administering the Plan, the Administrator
will be entitled, to the extent permitted by law, to rely conclusively on all
tables, valuations, certificates, opinions and reports which are furnished by
any accountant, trustee, counsel, actuary, insurance company or other expert 
who is employed or engaged by the Administrator or by Abbott or the Corporation
on the Administrator's behalf.

    9.5  CLAIMS AND REVIEW PROCEDURES.  The Administrator shall adopt
procedures for the filing and review of claims in accordance with ERISA section
503.

    9.6  INDEMNIFICATION OF ADMINISTRATOR AND ASSISTANTS.  The Corporation
agrees to indemnify and defend to the fullest extent of the law any of its or
Abbott's employees or former employees who serves or has served as 
Administrator or who has been appointed to assist the Administrator in 
administering the Plan or to whoever the Administrator has delegated any of its
duties or responsibilities against any liabilities, damages, costs and expenses
(including attorneys' fees and amounts paid in settlement of any claims 
approved by the Corporation) occasioned by any act or omission to act in 
connection with the Plan, if such act or omission to act is in good faith.

    9.7  EXPENSES AND COMPENSATION.  No compensation shall be paid to the
Administrator or any assistant who is a full-time employee of Abbott, the
Corporation, an Affiliated Corporation or a Subsidiary, but the Administrator
and his or her assistants shall be reimbursed for all expenses reasonably
incurred in the administration of the Plan.  Such expenses shall be charged to
the Trust and paid first out of the dividends paid on Abbott Stock held in the
Unallocated Account and then from




                                      26

Employer Contributions prior to allocation under Section 3.5, unless the 
Employers pay such expenses directly.  To the extent that any recordkeeping 
expense, withdrawal charge, loan fee or check fee is specifically 
attributable to a Participant's Accounts, such expenses may be charged to 
the Accounts of such Participant. 

    9.8  NOTICES; PARTICIPANT INFORMATION.  Any notice required to be given to
or any document required to be filed with the Administrator, the Trustee or the
Committee will be given or filed properly if mailed by registered mail, postage
prepaid, or delivered, to the Administrator, the Trustee or the Committee, as
the case may be, in care of the Corporation.  Participants (and their
Beneficiaries) must furnish to the Administrator such evidence, data, or
information as they consider necessary or desirable for the purpose of
administering the Plan, and the provisions of the Plan for each person are upon
the condition that he or she will furnish full, true and complete evidence, 
data and information requested by the Administrator.

                   ARTICLE 10.  AMENDMENT AND TERMINATION

    10.1 AMENDMENT.  The Corporation (through the Board of Directors) 
reserves the power at any time or times to amend the provisions of the Plan 
and Trust to any extent and in any manner that it may deem advisable.  The 
Corporation specifically reserves the right to amend Article 5 with respect 
to the investment of Participant Accounts.  However, the Corporation will 
not have the power:

         (a)  to amend the Plan or Trust in such manner as would cause or 
permit any part of the assets of the Trust to be diverted to  purposes other 
than for the exclusive benefit of each Participant and his or her Beneficiary 
(except as permitted by Section 13.3 with respect to Qualified Domestic 
Relations Orders, or by Section 3.9 with respect to the return of 
contributions upon nondeductibility or mistake of fact), unless such 
amendment is required or permitted by law, governmental regulation or ruling; 
or 

         (b)  to amend the Plan or Trust retroactively in such a manner as 
would reduce the accrued benefit of ERISA section 204(g) of any Participant, 
except as otherwise permitted or required by law; or

         (c)  to change the duties or liabilities of the Trustee, the Committee
or the Administrator without their consent.




                                      27


    10.2 TERMINATION.  The Corporation has established the Plan and 
authorized the establishment of the Trust with the bona fide intention and 
expectation that contributions will be continued indefinitely, but the 
Corporation will have no obligation or liability whatsoever to maintain the 
Plan for any given length of time and may discontinue contributions under the 
Plan or terminate the Plan at any time by written notice delivered to the 
Trustee and the Committee without liability whatsoever for any such 
discontinuance or termination. 

    10.3 DISTRIBUTIONS UPON TERMINATION OF THE PLAN.  Upon termination of the 
Plan by the Corporation, the Trustee will distribute to each Participant (or 
other person entitled to distribution) the value of the Participant's 
Accounts determined as of the Valuation Date coinciding with or next 
following the date of the Plan's termination.  However, if a successor plan 
is established, Accounts shall be distributed to Participants and their 
Beneficiaries only in accordance with Article 6 relating to in-service 
withdrawals and upon the actual separation from service by the Participant.

    10.4 MERGER OR CONSOLIDATION OF PLAN; TRANSFER OF PLAN ASSETS.  In case 
of any merger or consolidation of the Plan with, or transfer of assets and 
liabilities of the Plan to, any other plan, provision must be made so that 
each Participant would, if the Plan then terminated, receive a benefit 
immediately after the merger, consolidation or transfer which is equal to or 
greater than the benefit he or she would have been entitled to receive 
immediately before the merger, consolidation or transfer if the Plan had then 
terminated.

                    ARTICLE 11.  LIMITS ON CONTRIBUTIONS
                                           
    11.1 PR-CODE SECTION 1023(n) LIMITS.  The sum of the contributions made 
by the Employers under the Plan for any Plan Year shall not exceed the 
maximum amount deductible under the applicable provisions of the PR-Code (all 
such contributions being hereby conditioned on their deductibility under 
PR-Code section 1023(n)).



                                       28


11.2 PR-CODE SECTION 1165(e)(7)(A) LIMITS.

    (a)  IN GENERAL.  The maximum amount of Pre-Tax Contributions made on 
behalf of any Participant for any calendar year, when added to the amount of 
elective deferrals under all other plans, contracts and arrangements of Abbott, 
the Corporation, all Affiliated Corporations and all Subsidiaries with respect 
to the Participant for the calendar year, shall in no event exceed the lesser 
of 10% of the Participants' Compensation or $7,000 or any other applicable 
limit in effect for the calendar year under PR-Code section 1165(e)(7)(A).

    (b)  DISTRIBUTION OF EXCESS DEFERRALS.  In the event that an amount is 
included in a Participant's gross income for a taxable year as a result of an 
excess deferral under PR-Code section 1165(e)(7)(A), and the Participant 
notifies the Administrator on or before the March 1 following the taxable year 
that all or a specified part of a Pre-Tax Contribution made or to be made for 
his or her benefit represents an excess deferral, the Administrator shall make 
every reasonable effort to cause such excess deferral, adjusted for allocable 
income or loss, to be distributed to the Participant no later than the April 15 
following the calendar year in which such excess deferral was made.  No 
distribution of an excess deferral shall be made during the taxable year in 
which the excess deferral was made unless the correcting distribution is made 
after the date on which the Plan received the excess deferral and both the 
Participant and the Plan designates the distribution as a distribution of an 
excess deferral.  The amount of any excess deferrals that may be distributed to 
a Participant for a taxable year shall be reduced by the amount of Pre-Tax 
Contributions that were excess contributions and were previously distributed to 
the Participant for the Plan Year beginning with or within such taxable year.

    11.3 PR-CODE SECTION 1165(E)(3) LIMITS.

    (a)  ACTUAL DEFERRAL RATIOS.  For each Plan Year, the Administrator will 
determine the "actual deferral ratio" for each Participant who is eligible for 
Pre-Tax Contributions.  The actual deferral ratio shall be the ratio, 
calculated to the nearest one-hundredth of one percent, of the Pre-Tax 
Contributions made on behalf of the Participant for the Plan Year to the 
Participant's Compensation for the applicable period.  For purposes of 
determining a Participant's actual deferral ratio,

         (i)  Pre-Tax Contributions will be taken into account only to the 
    extent permitted by the PR-Code and the Regulations;

         (ii)  The applicable period for each Participant for a given Plan Year 
    shall be that portion of the 12-month period ending on the last day of such 
    Plan Year during which the individual was a Participant.

         (iii)  Employer Contributions may be treated as Pre-Tax Contributions 
    to the extent permitted by the PR-Code and the Regulations. 

    (b)  ACTUAL DEFERRAL PERCENTAGES.  The actual deferral ratios for all 
Highly Compensated Employees who are eligible for Pre-Tax Contributions for a 
Plan Year shall be averaged to determine the actual deferral percentage for the 
highly compensated group for the Plan Year, and the actual deferral ratios for 
all Employees who are not Highly Compensated Employees but who are eligible for 
Pre-Tax Contributions for the Plan Year shall be averaged to determine the 
actual deferral percentage for the nonhighly compensated group for the Plan



                                       29


Year.  The actual deferral percentages for any Plan Year must satisfy at least 
one of the following tests, which shall be interpreted and applied by the 
Administrator in a manner consistent with the PR-Code and the Regulations:

         (i)  The actual deferral percentage for the highly compensated group 
    does not exceed 125 percent of the actual deferral percentage for the 
    nonhighly compensated group; or

         (ii)  The excess of the actual deferral percentage for the highly 
    compensated group over the actual deferral percentage for the nonhighly 
    compensated group does not exceed two percentage points, and the actual 
    deferral percentage for the highly compensated group does not exceed twice 
    the actual deferral percentage of the nonhighly compensated group.

    (c)  ADJUSTMENTS BY ADMINISTRATOR.  If, prior to the time all Pre-Tax 
Contributions for a Plan Year have been contributed to the Trust, the 
Administrator determines that Pre-Tax Contributions are being made at a rate 
which will cause the PR-Code section 1165(e)(3) limits to be exceeded for the 
Plan Year, the Administrator may, in its sole discretion, limit the amount of 
Pre-Tax Contributions to be made with respect to one or more Highly Compensated 
Employees for the balance of the Plan Year by suspending or reducing Pre-Tax 
Contribution elections to the extent the Administrator deems appropriate.  Any 
Pre-Tax Contributions which would otherwise be made to the Trust shall instead 
be paid in cash to the affected Participant.

    (d)  EXCESS CONTRIBUTIONS.  If the PR-Code section 1165(e)(3) limits have 
been exceeded for a Plan Year after all contributions for the Plan Year have 
been made, the Administrator shall determine the amount of excess contributions 
with respect to Participants who are Highly Compensated Employees.  To do so, 
the Administrator shall reduce the actual deferral ratio of the Highly 
Compensated Employee with the highest actual deferral ratio to the extent 
necessary to (i) enable the Plan to satisfy the 1165(e)(3) limits or (ii) cause 
such Employee's actual deferral ratio to equal the actual deferral ratio of the 
Highly Compensated Employee with the next highest actual deferral ratio, and 
shall repeat this process until the Plan no longer exceeds the PR-Code section 
1165(e)(3) limits.  The amount of excess contributions for each Highly 
Compensated Employee for the Plan Year shall equal the amount of Pre-Tax 
Contributions (plus Employer Contributions  which are treated as Pre-Tax 
Contributions for purposes of the PR-Code section 1165(e)(3) limits) actually 
made to the Trust for the Plan Year, less the product of the (i) the Highly 
Compensated Employee's reduced actual deferral ratio as determined under the 
preceding sentence, and (ii) his or her Compensation.  Any excess contributions 
will be distributed as provided below.  In no event will excess contributions 
remain unallocated or be allocated to a suspense account for allocation in a 
future Plan Year.

    (e)  RECHARACTERIZATION OF EXCESS CONTRIBUTIONS.  At the option of 
the Administrator, a Participant's excess contributions may be 
recharacterized as After-Tax Contributions, provided the Administrator 
complies with the reporting requirements of the PR-Code for such 
contributions and such recharacterization occurs no later than the March 
15 following the Plan Year for which the contributions were made.

    (f)  DISTRIBUTION OF EXCESS CONTRIBUTIONS.  A Participant's excess 
contributions, adjusted for income or loss, will be designated by the 
Employer as a distribution of excess contributions and distributed to the 
Participant. Distribution of excess contributions will be made after the 
close of the Plan Year to which the contributions relate, but within 12 
months after the close of such Plan Year. 



                                      30


    (g)  SPECIAL RULES.  For purposes of distributing excess 
contributions,

         (i)  the amount of excess contributions that may be distributed with 
    respect to a Highly Compensated Employee for a Plan Year shall be reduced 
    by the amount of excess deferrals previously distributed to the Highly 
    Compensated Employee for his or her taxable year ending with or within such 
    Plan Year.

         (ii)  Any distribution of less than the entire amount of excess 
    contributions with respect to a Highly Compensated Employee shall be 
    treated as a pro rata distribution of excess contributions and allocable 
    income or loss.

    (h)  RECORDKEEPING REQUIREMENT.  The Administrator, on behalf of the 
Employer, shall maintain such records as are necessary to demonstrate 
compliance with the PR-Code section 1165(e)(3) limits including the 
extent to which qualified matching contributions and Qualified 
Nonelective Employer Contributions are taken into account in determining 
the actual deferral ratios.

             ARTICLE 12.  ROLLOVER AND TRANSFER CONTRIBUTIONS

    12.1 CONTRIBUTION OF AMOUNT DISTRIBUTED FROM ANOTHER QUALIFIED PLAN.  An 
Eligible Employee who was formerly a participant in a plan described in 
section 1165(a) of the PR-Code (the "distributing plan") and who has received 
a total distribution (within the meaning of section 1165(b) of the PR-Code) 
from the distributing plan (the "distribution") may, within 60 days of 
receipt of the distribution from the distributing plan, contribute to the 
Trust, as a "Rollover Contribution", such distribution if it: 

         (a)  does not exceed the fair market value of the distribution, and

         (b)   includes no property other than (i) money received in the 
    distribution, and (ii) money attributable to other property received in 
    the distribution which is sold and the proceeds of which are transferred.

    12.2     MONITORING OF ROLLOVERS.

         (a)  The Administrator shall establish such procedures and require 
    such information from employees seeking to make Rollover Contributions as 
    it deems necessary to insure that such Contributions satisfy the 
    requirements for tax-free rollovers established by conditions of this 
    Article and the PR-Code and the Regulations.

         (b)  No amount may be contributed or transferred under this Article 
    until approved by the Administrator.



                                       31


    12.3 TRANSFER CONTRIBUTION.  Subject to such restrictions and procedures 
as the Administrator may prescribe (which, without limitation, may include 
restrictions as to the type of plan from which transfers will be permitted), 
amounts held for the benefit of an Eligible Employee under a plan that is 
qualified under section 1165(a) of the PR-Code and exempt from tax under 
section 1165(a) of the PR-Code (the "distributing plan") may be transferred 
(the "Transfer Contribution") directly by the distributing plan to this Plan. 
 A Transfer Contribution Account shall be established for each Eligible 
Employee for whom a Transfer Contribution is made.  To the extent determined 
by the Administrator to be required under section 204(g) of ERISA, an 
Eligible Employee for whom a Transfer Contribution Account is maintained 
shall be entitled to distributions and withdrawals from such Account under 
provisions not less restrictive than applied under the distributing plan.  To 
the extent the distributing plan was subject to the requirements of section 
205 of ERISA, such requirements shall continue to apply to the transferred 
amount.

    12.4 TREATMENT OF TRANSFERRED AMOUNT UNDER THE PLAN.

         (a)  An individual who makes a Rollover Contribution to the Trust or 
    has a Transfer Contribution made to the Trust on his or her behalf shall 
    not be eligible to make or receive any other contributions under the Plan 
    until he or she has actually become a Participant and satisfied the 
    eligibility requirements otherwise applicable to such contributions.  
    However, for all other purposes under the Plan (including without 
    limitation, investment directions and distributions), an individual who 
    makes a Rollover Contribution or for whom a Transfer Contribution has 
    been made shall be treated as a Participant.

                              ARTICLE 13.  MISCELLANEOUS

     13.1 EXCLUSIVE BENEFIT RULE.  No part of the corpus or income of the 
Trust forming part of the Plan will be used for or diverted to purposes other 
than for the exclusive benefit of each Participant and Beneficiary, except as 
otherwise provided under the provisions of the Plan relating to Qualified 
Domestic Relations Orders, and the return of contributions upon 
nondeductibility, mistake of fact, or the failure of the Plan to qualify 
initially.



                                       32


    13.2 LIMITATION OF RIGHTS.  Neither the establishment of the Plan or the 
Trust, nor any amendment thereof, nor the creation of any fund or account, 
nor the payment of any benefits, will be construed as giving to any 
Participant or other person any legal or equitable right against Abbott, the 
Corporation, any Affiliated Corporation, any Subsidiary, the Administrator, 
the Trustee, or the Committee except as provided herein, and in no event will 
the terms of employment or service of any Participant be modified or in any 
way be affected hereby.  It is a condition of the Plan, and each Participant 
expressly agrees by his or her participation herein, that each Participant 
will look solely to the assets held in the Trust for the payment of any 
benefit to which he or she is entitled under the Plan.

    13.3 NONALIENABILITY OF BENEFITS.  The benefits provided hereunder will 
not be subject to alienation, assignment, garnishment, attachment, execution 
or levy of any kind, and any attempt to cause such benefits to be so 
subjected will not be recognized, except to the extent as may be required by 
law; provided, however, that if the Administrator receives any Qualified 
Domestic Relations Order that requires the payment of benefits hereunder or 
the segregation of any Account, such benefits shall be paid, and such Account 
segregated, in accordance with the applicable requirements of such Qualified 
Domestic Relations Order.

    13.4 CHANGES IN VESTING SCHEDULE.  A Plan amendment which changes a 
vesting schedule under the Plan shall apply with respect to any Participant 
who has completed three Years of Service prior to the expiration of the 
period described below only to the extent that the Participant's vested 
percentage in his or her Accounts determined under the amendment is greater 
than the nonforfeitable percentage of his or her Accounts determined without 
regard to the amendment. The period referred to in the preceding sentence 
will begin on the date the amendment of the vesting schedule is adopted and 
will end 60 days after the latest of the following dates:



                                       33


         (a)  the date on which such amendment is adopted;

         (c)  the date on which the Participant is issued written notice of 
    such amendment by the Administrator.

    13.5 GOVERNING LAW.  The Plan and Trust will be construed, administered 
and enforced according to the laws of the Commonwealth of Puerto Rico to the 
extent such laws are not preempted by ERISA.

        consecutive months;
        
            (iii)  a period of severance is a continuous period of time 
        during which the Employee is not employed by the Corporation, an 
        Affiliated Corporation or a Subsidiary.  Such period begins on the 
        date the Employee retires, quits or is discharged, or if earlier, 
        the 12-month anniversary of the date on which the Employee was 
        otherwise first absent from service; and

    considered a Period of Credited Service.

constitutes a "qualified domestic relations order" within the meaning of 
ERISA section 206(d)(3)(B).  A judgment, decree or order shall not be

pending distribution to an alternate payee) before the Participant is 
otherwise entitled to a distribution under the Plan.

Abbott Laboratories

and

Ms. Ellen M. Walvoord, Plan Administrator 
of the Abbott Laboratories Stock Retirement Program

Gentlemen and Ms. Walvoord:

I have examined the Registration Statement on Form S-8 to which this is an
exhibit, to be filed with the Securities and Exchange Commission in connection
with the registration under the Securities Act of 1933, as amended, of 7,000,000
common shares of Abbott Laboratories, without par value, and of an indeterminate
amount of interests to be offered or sold pursuant to the Abbott Laboratories
Stock Retirement Program, all as described more fully in said Registration
Statement.  I, or a member of my staff, have also examined copies of the
Articles of Incorporation and By-laws of Abbott Laboratories (the "Company"), as
amended, the Abbott Laboratories Stock Retirement Trust (the "Trust"), the
Abbott Laboratories Stock Retirement Trust (Puerto Rico) (the "Puerto Rico
Trust") and the Abbott Laboratories Stock Retirement Program (the "Program"),
and all amendments to the Trust, the Puerto Rico Trust and the Program to the
date hereof.  In addition, I have made such other examinations and have
ascertained or verified to my satisfaction such additional facts as I deem
pertinent under the circumstances.

On the basis of such examinations, I am of the opinion that:

1.  Abbott Laboratories is a corporation duly organized and existing under the
    laws of the State of Illinois, with corporate power to own and operate the
    property now owned by it.

2.  The common shares to be offered and sold under the Program may be (a) such
    as have been purchased for that purpose from the holders thereof; or (b)
    such as shall be newly issued by Abbott Laboratories, all as described more
    fully in said Registration Statement.  All legal and corporate proceedings
    necessary to the authorization and issuance of the common shares heretofore
    issued have been duly taken and such common shares have been legally
    issued, and when utilized for the purposes of the Program according to the
    provisions thereof, will be legally issued, fully paid and nonassessable
    outstanding common shares of the Company.  As to such common shares as may
    be issued hereafter, either directly for the purposes of the Program or
    issued for other purposes and then acquired from the holders, they will,
    upon due amendment of the Articles of Incorporation and due authorization
    of the Board of Directors, if required, and upon receipt of the
    consideration for said common shares specified by the Board of Directors,
    be legally issued and, when utilized for the purposes of the Program
    according to the provisions thereof, be legally issued, fully paid and
    nonassessable outstanding common shares of the Company.


                                                                 Exhibit 23.2

                      CONSENT OF INDEPENDENT PUBLIC ACCOUNTANTS

by reference in this registration statement of: (i) our supplemental report
