               (As Amended and Restated Effective January 1, 1996
                  and as further amended thru the 1st Amendment
                           effective January 1, 1997)

                  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


<PAGE>

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 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.

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, the Abbott Laboratories
Stock Retirement Trust (the "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.

     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.

     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 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.


<PAGE>

     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.

                (ii)   If the Employee's number of consecutive Break Years
           equals or exceeds the greater of 5 years or the aggregate 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 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


                                        2
<PAGE>

     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
     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


                                        3
<PAGE>

     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 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
     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
<PAGE>

     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. Only those Participants who make the
Basic Contributions required under Section 3.2 or who are not yet eligible to
make those Basic Contributions because they have not completed two Years of
Credited Service may make Supplemental Contributions. All Supplemental
Contributions shall be made in multiples of 1% of the Participant's
Compensation. If a Participant makes the Basic Contributions required under
Section 3.2, then the Participant's Supplemental Contributions may not exceed
16% of his or her Compensation. If a Participant is not yet eligible to make
the Basic Contributions required under Section 3.2, then the minimum
Supplemental Contribution that the Participant may make shall be an amount
equal to 2% of his or her Compensation and the aggregate amount of the
Participant's Supplemental Contributions may not exceed 18% of his or her
Compensation. The Participant


                                        5
<PAGE>

shall elect in the Contribution Agreement described in Section 3.4 to make
such contributions as Supplemental Pre-Tax Contributions, as Supplemental
After-Tax Contributions, or both, as applicable. No Employer Contributions
under Section 3.5 shall be made with respect to 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 and/or
Under-Payment Expenses (where Under-Payment Expenses mean the correction of
the under-payment of contributions to the Accounts of Participants due to
system or administrative errors, which correction shall be in accordance with
administrative procedures established by the Administrator).

     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;


                                        6
<PAGE>

           (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 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


                                        7
<PAGE>

     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.

     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 for any calendar month 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 no later than the 15th business day of the next following month. 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.


                                        8
<PAGE>

     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 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.


                                        9

                         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 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
5.5 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 Employer Contributions, all Basic Contributions
made before January 1, 1999, and all dividends and earnings received on those
Employer and Basic Contributions shall be invested in shares of Company Stock
unless and until they are transferred to another Investment Fund then
available under the Plan pursuant to the Plan's Pre-Retirement Feature
described in Section 5.4. A Participant may also direct that some or all of
his or her Basic Contributions made on or after January 1, 1999, 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 and the Guaranteed Income Option under the Prior Plan as of December
31, 1995 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 Article 5. In addition, a Participant may direct that


                                        10
<PAGE>

some or all of his or her Supplemental Contributions, Rollover Contributions,
or Transfer Contributions made on or after January 1, 1996 and Basic
Contributions made on or after January 1, 1999 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 direct that some or all
of his or her (i) Basic Contributions made on or after January 1, 1999, and
(ii) Supplemental Contributions, Rollover Contributions or Transfer
Contributions be invested 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 5.1 and 5.4, a Participant may instruct the Trustee that amounts
held in his or her Accounts that are invested in Company 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 Company Stock or any of the Investment Funds then
available under the Plan in accordance with the procedures established under
Section 5.5.

     5.4.  PRE-RETIREMENT FEATURE FOR REINVESTMENT OF COMPANY STOCK. 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.

     Employer 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 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 5.5.

     The restrictions described in this Section 5.4 shall apply to the
Accounts of all Participants.

     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 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


                                        11
<PAGE>

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 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 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, 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.

     5.8.  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 and/or Under-Payment Expenses, as
defined in Section 3.5. 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.

     5.9.  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


                                        12
<PAGE>

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 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


                                        13
<PAGE>

     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 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.

                (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.


                                        15
<PAGE>

                (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.

           (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, 1997 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:

           (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


                                        17
<PAGE>

           (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.

           (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.


                                        18
<PAGE>

     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. Loan repayments will be suspended under the Plan
as permitted under Code section 414(u)(4).

     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 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.


                                        19
<PAGE>

     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 5.6. 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. 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
Section 5.4 be considered to be 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 $5,000 and who has not yet attained age 65,
however, distribution may not be made under this Section unless:


                                        20
<PAGE>

           (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
$5,000 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 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. Unless the Participant otherwise elects, the payment of
benefits under the Plan to the Participant will begin not later than the 60th
day after the latest of the close of the Plan Year in which: (A) the date on
which the Participant attains the earlier of age 65 or the normal retirement
age specified under the Plan, (B) occurs the 10th anniversary of the year in
which the Participant commenced participation in the Plan, or (C) the
Participant terminates his service with the Employer.

     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


                                        21
<PAGE>

     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 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. At least 30 but nor more than 90 days prior to the date on
           which a Participant may begin to receive Plan benefits, (or, if
           the Participant elects, at least 7 days before payment of his or
           her benefits

                                        22
<PAGE>

           commences), 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, an election to waive the joint and survivor annuity, the
           requirement of spousal consent to such a waiver, and the
           Participant's right to make and the effect of 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 $5,000 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 $5,000 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 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


                                        23
<PAGE>

     no later than the December 31 of the Plan Year in which the Participant
     would have attained age 70_.

           (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 $5,000 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 $5,000 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.

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.


                                        24
<PAGE>

     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 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.


                                        25
<PAGE>

     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.


                                        26
<PAGE>

     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:

           (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


                                        27
<PAGE>

     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. Upon termination or partial termination of the
Plan, or upon complete discontinuance of contributions under the Plan, the
rights of all affected employees to benefits accrued to the date of such
termination, partial termination, or discontinuance, to the extent funded as
of such date, or the amounts credited to the employees' accounts, shall be
nonforfeitable.

     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


                                        28
<PAGE>

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. 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 such greater amount as
     may be determined by the Secretary of the Treasury for the limitation
     year), 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. The provisions of the
     immediately preceding sentence shall not be effective for any limitation
     year beginning after December 31, 1999. 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


                                        29
<PAGE>

     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 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


                                      30

<PAGE>

     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 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)   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 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:

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


                                        31
<PAGE>

                (ii)   The excess of the actual deferral percentage for any
           Plan Year for the highly compensated group over the actual
           deferral percentage for the immediately preceding Plan Year for
           the nonhighly compensated group does not exceed two percentage
           points, and the actual deferral percentage for any Plan Year for
           the highly compensated group does not exceed twice the actual
           deferral percentage for the immediately preceding Plan Year 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 amount to the extent necessary to (i) enable the
     Plan to satisfy the 401(k)(3) limits or (ii) cause such Employee's
     actual deferral amount to equal the actual deferral amount of the Highly
     Compensated Employee with the next highest actual deferral amount, 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.

           (e)   RECHARACTERIZATION OF EXCESS CONTRIBUTIONS. At the option of
     the Administrator, a Participant's excess contributions may be
     recharacterized as After-Tax


                                        32
<PAGE>

     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.
     Recharacterized excess contributions will remain subject to the
     nonforfeitability requirements and distribution limitations that apply
     to Pre-Tax contributions.

           (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).

           (j)   RULES FOR PRE-TAX CONTRIBUTIONS. The availability of Pre-Tax
     Contributions shall not discriminate in favor of Highly Compensated
     Employees. Amounts attributable to Pre-Tax Contributions may not be
     distributed except in accordance with the terms of the Plan and in no
     event earlier than upon one of the following events: (i) the employee's
     retirement, death, disability or separation from service; (ii) the
     termination of the Plan without establishment or maintenance of another
     defined contribution plan; (iii) the


                                        33
<PAGE>

     employee's attainment of age 59-1/2 or the employee's hardship; (iv) the
     sale or other disposition by an adopting Employer to an unrelated
     corporation of substantially all of the assets used in a trade or
     business, but only with respect to employees who continue employment
     with the acquiring corporation and the acquiring corporation does not
     maintain the Plan after the disposition; and (v) the sale or other
     disposition by an adopting Employer of its interest in a subsidiary to
     an unrelated entity but only with respect to employees who continue
     employment with the subsidiary and the acquiring entity does not
     maintain the Plan after the disposition.

     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,

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

                (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)   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 Plan Year
           for the highly compensated group does not exceed 125 percent of
           the actual contribution percentage for the immediately preceding
           Plan Year for the nonhighly compensated group; or


                                        34
<PAGE>

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

           (c)   MULTIPLE USE OF ALTERNATIVE LIMITATION. In accordance with
     Treasury Regulation 1.401(m)-2(c), multiple use of the alternative
     limitation which occurs as a result of testing under limitations
     described in Sections 11.4 and 11.5 will be corrected in the manner
     described in Treasury Regulation 1.401(m)-1(e). The term `alternative
     limitation' as used above means the alternative methods of compliance
     with Sections 401(k) and 401(m) of the Code contained in Sections
     401(k)(3)(A)(ii)(II) and 401(m)(2)(A)(ii) thereof, respectively.

           (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 amount to the
     extent necessary to (i) enable the Plan to satisfy the 401(m) limits or
     (ii) cause such employee's actual contribution amount to equal the
     actual contribution amount of the Highly Compensated Employee with the
     next highest actual contribution amount, 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


                                        35
<PAGE>

     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).
     Distributions under this Section 11.5(e) shall comply with the
     nondiscrimination requirements of Code section 401(a)(4).

           (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).

     11.6. AGGREGATION RULES. For purposes of Sections 11.4 and 11.5, all
Pre-Tax Contributions, After-Tax Contributions and Employer Contributions
made under two or more plans that are aggregated for purposes of Section
401(a)(4) and Section 410(b) of the Code (other than Section
410(b)(2)(A)(ii)) are to be treated as made under a single plan; and if two
or more plans are aggregated for purposes of Section 401(k) or Section 401(m)
of the Code, the aggregated plans must satisfy Section 410(b) and 401(a)(4)
of the Code as if they were a single plan. A Highly Compensated Employee's
actual deferral percentage under Section 11.4 and actual contribution
percentage under Section 11.5 shall be determined by treating all cash or
deferred arrangements under which such employee is eligible as one
arrangement.

                 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


                                        36
<PAGE>

     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 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


                                        37
<PAGE>

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.

           (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


                                        38

on the Participant's Years of Credited Service:

- -------------------------          -------------------------
<S>                                <C>
      less than 2                       0%

</TABLE>

     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 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

                                        39
<PAGE>

           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.

                (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.

                           ARTICLE 14. MISCELLANEOUS

     14.1. 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

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

Trust, nor any


                                        40
<PAGE>

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

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

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

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

     401(a)(17) Limitation for 1996 is $150,000.

Plan pursuant to its provisions or other individual for whom an Account is
maintained.

    15.34. "Period of Credited Service" means with respect to any Employee
the aggregate of all time periods beginning on the date the Employee first
completes an Hour of Service or is reemployed and ending on the date a Break
Year begins, subject to the following adjustments:

           (a)   An Employee will be credited with one Year of Credited
     Service for each year of credited service under the Plan as in effect
     prior to October 1, 1988.

           (b)   On or after October 1, 1988, an Employee shall be credited
     with 1/12th of a Year of Credited Service for each calendar month of
     employment (or portion thereof) during which he or she is employed by
     the Corporation, an Affiliated Corporation or a Subsidiary, including
     employment prior to October 1, 1988; provided, however that the Employee
     will not be credited with less service than was credited to him as of
     September 30, 1988.

           (c)   An Employee will also receive credit for any period of
     severance of less than 12 consecutive months. Fractional periods of a
     year will be expressed in terms of days. In the case of an individual
     who is absent from work for maternity or paternity reasons, the
     12-consecutive month period beginning on the first anniversary of the
     first day of such absence shall not constitute a Break Year. For
     purposes of this Section,

                 (i)   an absence from work for maternity or paternity
           reasons means an absence (A) by reason of the pregnancy of the
           individual, (B) by reason of the birth of a child of the
           individual, (C) by reason of the placement of a child with the

           individual, or (D) for purposes of caring for such child for a
           period beginning immediately following such birth or placement;

                (ii)   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

               (iii)   in the case of a leave of absence for service in the
           armed forces of the United States, no period shall be excluded
           under this paragraph during which the Employee has reemployment
           rights with respect to the Corporation, any Affiliated Corporation
           or any Subsidiary under federal law and contributions, benefits
           and service credit with respect to qualified military service will
           be allow or provided, as the case may be, in accordance with Code
           section 414(u).

           (d)   If, 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 any prior separate business entity, part or all of
     which is or was acquired by, or becomes part of an Employer will be
     considered a Period of Credited Service.

           (e)   All service earned by a MediSense Employee (as defined
     below) from his or her date of hire by MediSense, Inc. will be credited
     toward his or her Period of Credited Service for purposes of determining
     eligibility to make Basic Contributions under Section 2.1 and for
     purposes of determining the Employee's service points described in
     Section 3.5(b). For purposes of this Section 15.34(e), the term
     MediSense Employee shall mean an employee of MediSense, Inc., a
     Massachusetts corporation and an Affiliated Corporation.

           (f)   All service earned by a Sanofi Employee (as defined below)
     since his or her last date of hire, as shown on the records of Sanofi
     Pharmaceuticals, Inc., a Delaware corporation ("Sanofi"), will be
     credited by the Plan toward that Employee's Period of Credited Service
     for purposes of determining the Employee's eligibility to make Basic

     described in Section 3.5(b). For purposes of this Section 15.34(f), the

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 Income Tax 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 Abbott Health Products, Inc. and its affiliates in
Puerto Rico will encourage such investment by also making contributions to
the Trust. 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 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:

                                       2

<PAGE>


                           (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 14.22, 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 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






                                       3


<PAGE>


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







                                       4

<PAGE>


         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 Plan (other than Abbott Stock). If the Participant fails to
         make such election, such shares shall be sold and the sale proceeds
         shall be 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 or







                                       5

<PAGE>


         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 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 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 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
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.

         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 Puerto Rico
         securities laws to secure exemption under any rule of the Securities
         and Exchange Commission and/or the Puerto Rico Commissioner of
         Financial Institutions or to comply with the Corporation's corporate
         policy with respect to "blackout periods" related to Abbott Stock. Such
         restrictions shall apply to all






                                       6

<PAGE>


         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 Abbott Stock; (ii) moratoriums on
         loans and transfers into and out of Abbott Stock; and (iii)
         suspensions of Basic Contributions and Supplemental Contributions
         allocated to Abbott 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 Abbott 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 Basic
After-Tax Contribution, as the Participant elects; provided, however, that if
in order to satisfy the PR-Code Section 1165(e)(3) limits, the Participant's
Basic Pre-Tax Contributions need to be reduced or entirely suspended for the
remainder of a Plan Year, then the Participant's Contribution Arrangement
will be considered automatically amended to provide that the Participant's
Compensation for the remainder of the Plan Year shall be reduced by 2% and
the Employer will contribute to the Trust an equal amount as a Basic
After-Tax Contribution. For purposes of this Section 3.2, Compensation shall
be limited to that portion of his or her Compensation as is






                                       7

<PAGE>


determined from time to time by the Board of Directors. 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
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







                                       8

<PAGE>


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 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 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:

                  (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









                                       9

<PAGE>


         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 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








                                       10
<PAGE>


         shall be determined and allocated as of the end of the Plan Year
         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 (after adding earnings and deducting
         expenses as herein permitted) 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 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. 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 Directors 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 Abbott Laboratories for the
Plan Year. Except as otherwise expressly provided for, any Qualified
Nonelective Contribution Employer Contribution shall be treated as a








                                       11

<PAGE>


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 an 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 for any calendar month 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 no later than the 15th business day of the next following month. 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 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







                                       12
<PAGE>


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.

         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.







                                       13

<PAGE>


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 subaccounts 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, 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






                                       14

<PAGE>


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 Employer Contributions, all Basic
Contributions made before January 1, 1999, and all dividends and earnings
received on those Employer and Basic Contributions shall be invested in
shares of Abbott Stock unless and until they are transferred to another
Investment Fund then available under the Plan pursuant to the Plan's
Pre-Retirement Feature described in Section 5.4. A Participant may also
direct that some or all of his or her Basic Contributions made on or after
January 1, 1999, 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 Basic Contributions made on or after January 1,
1999, 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 (i) Basic Contributions made
on or after January 1, 1999, and (ii) Supplemental Contributions, Rollover
Contributions or Transfer Contributions 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 Sections 5.1 and 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







                                       15

<PAGE>


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.

         5.4      PRE-RETIREMENT FEATURE FOR REINVESTMENT OF ABBOTT STOCK. 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 in any of the other Investment
Funds described in Section 5.3.

                  Employer 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 in the Putnam Stable Value Fund
or in any of the other Investment Funds described in Section 5.3 in
accordance with the procedures established under Section 5.5.

                  The restrictions described in this Section 5.4 shall apply
to the Accounts of all Participants, including, but not limited to those who
have retired under the Abbott Puerto Rico Retirement Plan.

         5.5      DEFAULT INVESTMENT FUND. The Administrator shall, from time
to time, 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.

         5.6      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







                                       16

<PAGE>


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 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.

         5.7      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 such total withdrawals under
         this subsection (b) do not exceed the Participants 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 Supple-

                           mental 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:

                                    (C) 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.

                                    (D) 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.

                                       19

<PAGE>


                                    (ii) No more than one withdrawal may be
         elected in any calendar quarter; provided, however, that the
         Administrator, in his or her solediscretion, 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 REQUIRED DISTRIBUTIONS AFTER 70 1/2. 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 United States Internal
Revenue 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 1/2 and any subsequent year)
who attained age 70 1/2 before January 1, 1997 may defer receipt of the
distributions under this Section 6.3 until the April 1 following the calendar
year in which he or she retires or attains age 70 1/2, whichever is later.
Each distribution described in this Section 6.3 shall be made at the latest
possible date permitted under United States Internal Revenue Code section
401(a)(9) and Regulations thereunder and in accordance with such
administrative rules and practices as may be adopted by the Administrator.

         6.4 PARTICIPANT'S CONSENT TO DISTRIBUTION OF BENEFITS. If a
Participant receives a withdrawal under Section 6.1 or 6.2, or an Alternative
Payee receives a distribution under Section 6.3, 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 the April 1 after the Plan
         Year in which he or she attains age 70 1/2 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

                  (b) the Participant consents to the distribution in writing
         after the information

                                       21

<PAGE>


         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 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


                                       22

<PAGE>


                  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).

         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. All loans shall be
subject to such rules and procedures as the Administrator shall promulgate
from time to time pursuant to the authority granted in Section 7.2. 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


                                       23

<PAGE>

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 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 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

                                       24

<PAGE>


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 an 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 12.3 (if any), and 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 Abbott Stock) in which the applicable Account is invested until
such Investment Funds are exhausted, and then drawing from the applicable
Account the Abbott Stock held in each such Account.

         7.11 REINVESTMENT OF LOAN REPAYMENTS. Loan repayments shall be made
to the


                                       25

<PAGE>


Eligible Borrower's 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(s) then in
effect 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. 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
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.


                 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 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 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

                                       26

<PAGE>


prior Plan Year and distributed to the Participant in cash or Abbott 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 $5,000 and who has not yet attained age 70, 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
$5,000 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. Distributions in all events will commence no
later than the 60th day after the close of the Plan Year which occurs after
the later of the Participant's separation from service or the Participant's
attainment of age 70.

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. Alternatively, the Participant may
elect to defer the distribution of his or her Accounts until any date, but no
later than April 1 after the

                                       27

<PAGE>


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 Participant's
         Accounts under the Abbott Laboratories Stock Retirement Plan as of
         December 31, 1995. The provisions of such annuity contract shall be
         subject to the following:

                                            (A) 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) 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).

                                            (C) 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

                                       28

<PAGE>


                           shall be rendered nontransferable and, at the
                           Administrator's discretion, may be rendered
                           non-commutable.

                                            (D) If a Participant is married on
                           his or her annuity starting date (as defined herein),
                           and the Participant has elected to have his or her
                           benefits distributed by purchase of an annuity
                           contract, the value of the Participant's Accounts
                           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. At least 30 but nor more than 90
                           days prior to the date on which a Participant may
                           begin to receive Plan benefits, (or, if the
                           Participant elects, at least 7 days before payment of
                           his or her benefits commences), 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, an election to waive the
                           joint and survivor annuity, the requirement of
                           spousal consent to such a waiver, and the
                           Participant's right to make and the effect of
                           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) above, as the Participant
                           elects. The term "annuity starting date" for any
                           Participant means (a) the first day of the first
                           period for which a benefit is


                                       29

<PAGE>


                           payable to the Participant under the Plan as an
                           annuity, or (b) in the case of a benefit not
                           payable in the form of an annuity, the first day
                           on which all events have occurred which entitle
                           the Participant to such benefit.

                  (c) CASHOUT OF SMALL BENEFITS. If the value of a Participant's
         Accounts is $5,000 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
         $5,000 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 SINGLE SUM PAYMENTS. If a Participant
         or an Alternate Payee of the Participant is entitled to a single sum
         payment under Section 8.3(a), he or she may elect to have such payment
         transferred directly to another qualified plan, an individual
         retirement account, or an individual retirement annuity. The
         Administrator shall not be obligated 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 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 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 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


                                       30

<PAGE>


         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.

                  (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 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 $5,000 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
         $5,000 or less, if the value of such Accounts at the time in question
         or at the time of any prior distribution


                                       31

<PAGE>



         to the Participant under the Plan exceeds such amount.

                  (d) DIRECT ROLLOVER OF SINGLE SUM PAYMENTS. If a Beneficiary
         who is the spouse of a deceased Participant is entitled to a single sum
         payment under Section 8.3(a), he or she may elect to have such payment
         transferred directly to an individual retirement account or an
         individual retirement annuity. The Administrator shall not be obligated
         to honor any transfer instruction under this Section that specifies
         more than one transferee.

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


                                       32

<PAGE>


                  (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 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,


                                       33

<PAGE>


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 PR-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


                                       34

<PAGE>


         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 its authority in a
nondiscriminatory manner so that all persons similarly situated will receive
substantially the same treatment.

         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
Abbott or 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 or Abbott's 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


                                       35

<PAGE>


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 Employer Contributions prior to allocation under
Section 3.5, unless the Employers pay such expenses directly. To the extent
that any record keeping 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 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 (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:

                  (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


                                       36

<PAGE>


         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.

         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


                                       37

<PAGE>


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)).

         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


                                       38

<PAGE>


         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 $7,500 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


                                       39

<PAGE>



                  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 non-highly 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 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 non-highly compensated group; or

                           (ii) The excess of the actual deferral percentage
                  for the highly compensated group over the actual deferral
                  percentage for the non-highly 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 non-highly
                  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-


                                       40

<PAGE>


         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.


                                       41

<PAGE>


                  (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.

                  (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

section 1165(a) of the PR-Code (the "distributing plan") and who has received

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:

<PAGE>


                  (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 Rollover
         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.

         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. 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.

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.

         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


                                       44

<PAGE>


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:

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

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

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

                                   APPENDIX A

The provisions of this Appendix A shall apply to those accounts (the
"Transferred Account(s)") that were formerly maintained under the Abbott
Laboratories Stock Retirement Plan (the "Parent Company Plan") and that were
transferred to the Abbott Laboratories Stock Retirement Plan (Puerto Rico)
(the "Plan") effective June 23, 1998 (the "Transfer Date").

         1. Upon receipt by the Plan, each Transferred Account will be invested
         in the same investment funds as it was invested under the Parent
         Company Plan prior to the Transfer Date.

         2. Except as required by applicable law, any Participant loan
         outstanding under the Parent Company Plan on the Transfer Date shall
         remain outstanding under the Plan in accordance with its terms,
         notwithstanding any Plan provision limiting the number of loans a
         participant may have or the terms of those loans.

         3. The portion of each Transferred Account attributable to pre-tax,
         after-tax, or employer contributions under the Parent Company Plan
         will retain that characterization and will be subject to the
         applicable sections of the PR-Code governing such contributions,
         including but not limited to the sections governing the distribution
         of such contributions.

December 20, 1999

Abbott Laboratories
Abbott Park, Illinois 60064-6400

and

Mr. Thomas M. Wascoe, Plan Administrator
of the Abbott Laboratories Stock Retirement Program

Gentlemen and Mr. Wascoe:

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 4,000,000 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


<PAGE>

     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.

3.   The Program has been duly and legally authorized and adopted and both the
     Trust and the Puerto Rico Trust, created to implement the Program, have
     been duly and legally authorized and created. The Trust is a valid trust
     enforceable according to its terms under the laws of the State of
     Illinois and the participants in Part A of the Program have valid
     beneficial interests in the Trust, subject to the terms of the Trust and
     Part A of the Program. The Puerto Rico Trust is a valid trust enforceable
     according to its terms under the laws of the Commonwealth of Puerto Rico
     and the participants in Part B of the Program have valid beneficial
     interests in the Puerto Rico Trust, subject to the terms of the Puerto
     Rico Trust and Part B of the Program.

4.   The Program, the Trust, and the Puerto Rico Trust, as amended to the date
     hereof, comply with those requirements of the Employee Retirement Income
     Security Act of 1974 that are applicable to the same.

I hereby consent to the use of this legal opinion as an exhibit to the
Registration Statement to be filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended.

Very truly yours,


/s/ Jose M. de Lasa
