                       EMPLOYMENT AGREEMENT BY AND BETWEEN
               CARE MANAGEMENT SCIENCE CORPORATION AND STEVEN BELL

         WHEREAS Mr. Steven Bell (hereinafter "Executive") and Care Management
Science Corporation, a Pennsylvania corporation (hereinafter "Company") desire
and intend to enter into an employment relationship, all as set forth below;

         NOW THEREFORE, the parties hereto, in consideration of the promises and
mutual covenants and agreements contained herein, voluntarily and knowingly, and
intending to be legally bound hereby, covenant and agree as follows:

         1. EMPLOYMENT AND DUTIES.

                  (a) Company hereby employs Executive for the Term (as such
term is hereinafter defined) to render services to the Company as its Chief
Financial Officer. Executive shall have the overall charge of directing the
ongoing management and continued development and expansion of the Financial and
Administrative aspects of the Company and such other duties as may be directed
by the President from time to time. Executive shall be based within the
Philadelphia, PA metropolitan area, but may be required to travel from time to
time as part of his employment. Executive hereby accepts such employment and
agrees to render the services described herein, all on the terms and conditions
of this Agreement.

                  (b) Executive agrees to devote his entire working time,
attention and energies to the performance of the business of the Company and its
affiliates (as hereinafter defined); and Executive shall not, directly or
indirectly, alone or as a member of any partnership or other organization, or as
an officer, director or employee of any other corporation, partnership or other
organization, be actively engaged in or concerned with any other duties or
pursuits which, in the reasonable judgment of the Company, interfere with the
performance of his duties hereunder, or which, even if non-interfering, are
contrary to the best interests of the Company and its affiliates; PROVIDED,
HOWEVER, that Executive may invest his personal or family assets in such form or
manner as will not require any services on his part in the operation of the
affairs of the enterprises in which such investments are made and in which his
participation is solely that of a minority investor; FURTHER, PROVIDED, that the
Executive may engage in charitable, civic, fraternal or trade group activities,
so long as such activities shall not violate any provision of this Agreement or
interfere with his performance hereunder or compliance with the restrictions
contained herein. As used herein, the term "affiliate" means and includes any
person, corporation or other entity controlling, controlled by or under common
control with the Company.

         2. TERM OF EMPLOYMENT.

                  The term of Executive's employment under this Agreement (the
"Term") will commence as of FEBRUARY 15, 1999 (the "Effective Date") and shall
continue through February 15, 2002 (the "Initial Term"). In the absence of at
least ninety (90) days advance written notice

                                      -1-

from either party to the other prior to the expiration of the Initial Term, this
Agreement shall automatically renew for an additional one (1) year period (an
"Extension Term") on the same terms and conditions as defined herein.
Thereafter, this Agreement shall continue to renew for additional one (1) year
period(s) on the same terms and conditions as defined herein in the absence of
at least ninety (90) days advance written notice from one party to the other
prior to the expiration of any Extension Term. For the purposes of this
Agreement, the Initial Term along with any Extension Term(s) shall be referred
to collectively, as the "Term".

         3. COMPENSATION AND BENEFITS.

                  (a) As compensation for the services to be rendered by
Executive hereunder, including all services to any subsidiary of the Company,
the Company agrees to pay or cause to be paid to Executive, during the first
year of the term of his Employment hereunder, an annual base salary of $150,000
(the "Base Salary"). For each subsequent year of the Term, the Base Salary will
be reviewed annually by the Compensation Committee of the Board of Directors of
the Company. Executive's Base Salary shall be payable in such installments as is
the policy of the Company generally with respect to employees of the Company.

                  (b) In addition to his Base Salary, Executive shall be awarded
a stock option grant representing 96,719 shares, such award grant being attached
hereto as EXHIBIT 3(B) and incorporated by reference herein.

                  (c) Executive shall be awarded stock option grants under the
Company's performance-based Senior Management Incentive Stock Option Plan as
follows: option shares equal to 0.50% of the company's fully-diluted common
stock (at $2.59 per share) vesting in accordance with the performance-based
Senior Management Incentive Stock Option Plan in an "all-or-none" fashion at
December 31, 2000 (0.25%) and December 31, 2001 (0.25%) respectively upon the
attainment of performance goals as defined in the performance-based Senior
Management Incentive Stock Option Plan.

                  (d) Executive shall be eligible under any incentive plan,
stock option plan, bonus, profit participation, pension, group insurance or
other benefit plans (both qualified and non-qualified for federal tax purposes)
or other so-called "fringe" benefits, if any, which the Company generally
provides to its executives on the same terms and conditions, except that any
incentive compensation program for Executive will be reviewed by the
Compensation Committee of the Board of Directors of the Company.

                  (e) The Company shall pay or reimburse Executive for all
reasonable expenses actually incurred or paid by him during the Term in the
performance of his services under this Agreement, upon presentation of expense
statements or vouchers or such other supporting information as it reasonably may
require. For the purposes of this Agreement, "reasonable expenses" may include
Executive's actual expenses for required continuing professional education, so
long as Executive acts to keep those expenses to reasonable amount and so long
as those expenses do not exceed $1,000 per year in any event.

                  (f) The Company shall provide to Executive and the members of
his immediate family, medical and dental insurance covering its executives
generally and under the same terms and conditions.

                  (g) Executive shall be eligible under any group life and/or
disability insurance covering its executives generally and under the same terms
and conditions.

                  (h) Executive shall be entitled to four weeks paid vacation
plus all federal holidays, in each calendar year, with an additional day accrued
per year of completed service up to a maximum of four weeks vacation.

         4. CONFIDENTIALITY.

                  (a) Subject to the provisions below, Executive shall not,
during the Term of this Agreement, or at any time following the expiration or
termination of this Agreement, directly or indirectly, disclose or permit to be
known (other than (i) as is reasonably required in the regular course of his
duties, including disclosures to the Company's advisors and consultants, (ii) as
required by law or (iii) with the prior written consent of the Company), to any
person, firm corporation or entity, any confidential information acquired by him
during the course of or as an incident to, his employment or the rendering of
services hereunder, relating to the Company or any of its subsidiaries, or any
corporation, partnership or other entity owned or controlled, directly or
indirectly, by or controlling the Company or its subsidiaries. Such confidential
information shall include, but shall not be limited to, business affairs,
proprietary technology, trade secrets, patented or copyrighted processes,
research and development data, know-how, market studies and forecasts,
competitive analyses, pricing policies, employee lists, personnel policies, the
substance of agreements with customers, suppliers and others, marketing or
dealership arrangements, servicing and training programs and arrangements,
customer lists and any other documents embodying such confidential information.
This confidentiality obligation shall not apply to any confidential information
which becomes publicly available other than pursuant to a breach of this Section
4 by Executive or which was obtained from a third party not acquiring the
information under an obligation of confidentiality from the disclosing party and
intended for the benefit of the Company.

                  (b) All information and documents relating to the Company and
its affiliates as hereinabove described shall be the exclusive property of the
Company and upon termination of Executive's employment with the Company, all
documents, records, reports, writings and other similar documents containing
confidential information, including copies thereof, then in Executive's
possession or control shall be returned and left with the Company.

         5. NON-COMPETITION.

                  As a condition precedent to this Agreement, and in
consideration for this Employment Agreement and the associated Stock Option
Grant, Executive shall sign, contemporaneously with this Agreement, and abide by
a Non-Competition Agreement in the form attached hereto as EXHIBIT 5, (the
"Non-Competition Agreement").

         6. EQUITABLE REMEDIES AND ENFORCEABILITY OF COVENANTS.

(a) If Executive commits a breach, or threatens to commit a breach, of any of
the provisions hereof or under the Non-Competition or Invention Assignment
Agreements, it is acknowledged and agreed that any such breach or threatened
breach will cause irreparable injury

                                      -3-
<PAGE>

to the Company and that money damages will not provide an adequate remedy to the
Company.

                  (b) If any of the covenants contained herein or under the
Non-Competition or Invention Assignment Agreements, or any part hereof or
thereof, is hereafter construed to be invalid or unenforceable, the same shall
not affect the remainder of the covenant or covenants, which shall be given full
effect without regard to the invalid portions.

                  (c) If any of the covenants contained herein or under the
Non-Competition or Invention Assignment Agreements, or any part hereof or
thereof, is held to be unenforceable because of the duration of such provision
or the area covered thereby, the parties agree that the court making such
determination shall have the power to reduce the duration, scope and/or areas of
such provision and, in its reduced form, such provision shall then be
enforceable.

                  (d) The existence of any claim or cause of action by Executive
against the Company or any affiliate of the Company shall not constitute a
defense to the enforcement by the Company of the covenants contained herein, but
such claim or cause of action shall be litigated separately.

         7. TERMINATION BY THE COMPANY.

                  The Company may terminate Executive's employment under this
Agreement upon written notice to Executive if any one or more of the following
shall occur:

                  (a) There exists Cause for termination. For the purposes of
this Agreement, the term "Cause" means: (i) the willfull failure by Executive to
perform his duties or obligations hereunder (other than such failure resulting
from Executive's incapacity due to illness or leaves of absence approved by the
Company) PROVIDED such failure remains uncured for a period of 10 business days
after written notice describing the same is received by Executive; (ii)
Executive's conviction of any felonious crime or offense; (iii) the unauthorized
securing by Executive of any personal profit in connection with the business of
the Company or any of its subsidiaries; (iv) use of any unlawful controlled
substance under any circumstances or the use of alcohol to the extent that it
interferes with the performance of Executive's duties hereunder, or which, in
the good faith opinion of the Company, are harmful to the Company; (v) the
commission of any acts involving dishonesty or fraud, which, in the good faith
opinion of the Company, are harmful to the Company; or (vi) any breach by
Executive of the terms of Section 4 of this Agreement or under the
Non-Competition or Nondisclosure, Proprietary Information and Invention
Assignment Agreements; PROVIDED such breach continues uncured for 5 business
days after written notice of such breach has been received by Executive from the
Company.

                  (b) Executive's death during the Term; PROVIDED, HOWEVER, that
Executive's legal representatives shall be entitled to receive his Base Salary
through the last day of the second month after the month in which his death
occurs, along with any other compensation and benefits to which Executive and
his legal representatives may be entitled under applicable plans, programs and
agreements of the Company, including but not limited to, the proceeds of any
applicable life insurance policies through the date of death.

                  (c) Executive shall become physically or mentally disabled so
that he is unable to perform his services hereunder for a period of 90
consecutive days or 120 non-consecutive days in any 365 day period.
Notwithstanding such disability, the Company shall

                                      -4-
<PAGE>

continue to pay Executive his Base Salary through the date of such termination,
along with any other compensation and benefits to which Executive and his legal
representatives may be entitled under applicable plans, programs and agreements
of the Company, including but not limited to, the proceeds of any applicable
disability insurance policies also shall be paid through the date of such
termination.

                  (d) At the Company's sole discretion so long as Company pays
to Executive an amount equal to six (6) months Base Salary along with any other
compensation and benefits to which Executive may be entitled under applicable
plans, PRO RATED through the date of Executive's termination of employment (the
sum of these amounts collectively defines the "Severance Amount"). Payment of
such Severance Amount, if required, shall be made at the Company's option
either: (i) in equal monthly installments over six (6) months, or (ii) in a
lump-sum payment promptly following the termination of Executive's employment
equal to the then present value using a discount rate per annum determined by
reference to the discount rate then published by the Pension Benefit Guaranty
Corporation of the Severance Amount. For the purposes of this Agreement, the
decision by the Company not to renew this Agreement at the end of the Initial
Term or any Extension Term shall be considered to be "At the Company's sole
discretion" and Executive shall receive the Severance Amount on the terms and
conditions as defined herein. By contrast, any decision by the Executive not to
renew this Agreement at the end of the Initial Term or any Extension Term shall
make Executive ineligible for any Severance Amount. Notwithstanding the
foregoing, in the event that the Company sells all or substantially all of its
assets or the Company is acquired by or merges with another company resulting in
a "Change of Control" (defined herein as any one stockholder, other than David
J. Brailer, M.D., Ph.D., becoming a beneficial owner -- as defined in Rule 13-d
under the Exchange Act -- directly or indirectly, of securities of the Company
representing more than 50% of the Common Stock of the Company or the combined
voting power of the Company's then outstanding securities, and Executive is
terminated without cause within nine (9) months (whether before or after) of the
closing of the transaction, Executive shall receive twelve (12) months Base
Salary rather than the 6 months described above, but otherwise subject to the
same terms and conditions concerning payment.

         8. INVENTIONS DISCOVERED BY EXECUTIVE.

                  As a condition precedent to this Agreement, Executive shall
sign, contemporaneously with this Agreement, an Invention Assignment Agreement
in the form attached hereto as EXHIBIT 8 (the "Invention Assignment Agreement").

         9. REPRESENTATIONS AND AGREEMENTS OF EXECUTIVE.

                  (a) Executive represents and warrants that he is free to enter
into this Agreement and to perform the duties required hereunder, and that there
are no employment contracts or understandings, restrictive covenants or other
restrictions, whether written or oral, preventing the performance of his duties
hereunder or which would be harmful to the Company.

                  (b) Executive agrees to submit to a medical examination and to
cooperate and supply such other information and documents as may be required by
any insurance company in connection with the Company's obtaining life insurance
on the life of Executive, if the Company

                                      -5-
<PAGE>

so desires, or any other type of insurance or fringe benefits as the Company
shall determine from time to time to obtain.

         10. ARBITRATION.

                  Any controversy or claim arising out of or relating to this
Agreement (or breach thereof) shall be settled by arbitration in Philadelphia,
Pennsylvania, in accordance with the rules then existing of the American
Arbitration Association (three arbitrators), and judgment upon the award
rendered may be entered in any court having jurisdiction thereof.
Notwithstanding the foregoing, the Company, at its sole option, shall be
entitled to seek and obtain equitable relief from any court of competent
jurisdiction, including, without limitation, temporary, preliminary and
permanent injunctive relief and specific performance with respect to alleged
violations of Sections 4 and 5 of this Agreement, Section 1 of the
Non-Competition Agreement or under the Invention Assignment Agreement, and the
Company's pursuit of the remedies described in Section 6 hereof in connection
therewith. The parties shall be free to pursue any remedy before the arbitration
tribunal that they shall be otherwise permitted to pursue in a court of
competent jurisdiction. The award of the arbitrators shall be final and binding
and may be enforced by any court as if it were a judgment of that court, and may
include interest at a rate or rates considered just under the circumstances by
the arbitrators. The substantive law of the Commonwealth of Pennsylvania shall
be applied by the arbitrators to the resolution of the dispute, provided that
the arbitrators shall base their decision on the express terms, covenants and
conditions of this Agreement. The arbitrators shall be required to produce a
written decision setting forth the reasons for the decision or award to be made.
The parties agree that the arbitrators shall have no power to alter or modify
any express provision of this Agreement or to render any award which, by its
terms, effects any such alteration or modification. Upon written demand to any
party to the arbitration for the production of documents and things reasonably
related to the issues being arbitrated, the party upon whom such demand is made
shall promptly produce, or make available for inspection and copying, such
documents and things without the necessity of any action by the arbitrators. The
party which does not prevail in the arbitration shall be responsible for all
fees and expenses incurred, including, without limitation, reasonable attorneys'
fees, for both parties.

          11. NOTICES.

          CARE MANAGEMENT SCIENCE CORPORATION NON-COMPETITION AGREEMENT

                  Care Management Science Corporation, a Pennsylvania
corporation (the "Company") and Steven Bell ("Executive"), contemporaneously
with the execution of this Agreement are entering into an Employment Agreement
of even date herewith (the "Employment Agreement"), pursuant to which, among
other things, the Executive will be employed by the Company in the capacity of
its Chief Financial Officer. Capitalized terms used in this Agreement and not
otherwise defined herein shall have the meanings given such terms in the
Employment Agreement. In addition to the Company's desire to engage the
Executive and the Executive's desire to serve the Company, under the terms and
conditions of the Employment Agreement, the Executive understands that the
Company wishes to ensure that the Executive does not compete with the Company,
on the terms and conditions specified below and in the Employment Agreement, in
the event the Executive's employment with the Company is terminated.

                  In consideration of the Company's employment of me and in
order to induce the Company to employ me, the Company and Executive hereby agree
as follows:

                  1. NON-COMPETITION; APPLICATION AND DURATION;
NON-INTERFERENCE. The Executive will not, during the term of the Executive's

                           (a) as owner, partner, joint venturer, stockholder,
employee, broker, agent, principal, trustee, corporate officer, director,
licensor, or in any capacity whatsoever engage in, become financially interested
in, be employed by, or render any consultation or business advice with respect
to any business which business is engaged in by the Company on the date hereof
or during the course of Executive's employment or which business ("Company
Business") is engaged in development or commercialization of any technologies or
products related to the development of software and databases that transform
data into tools to be used by managers in the health care information industry
or the provision of services with respect thereto (collectively, "Clinical
Decision Support"), in any geographic area where, during the time of Executive's
employment, the business of the Company or any of its subsidiaries is being, had
been or was proposed to be, conducted in any manner whatsoever, which
technologies, products or services are (i) competitive with any Clinical
Decision Support or other Company Business technology or application thereof or
products based thereon designed, marketed, announced, leased or sold by the
Company or any of its subsidiaries during the term of employment or at the time
of the termination of the Executive's employment; or (ii) substantially similar
to any technology or service involving Clinical Decision Support or other
Company Business which the Company was designing, marketing, announcing, leasing
or selling or proposing to design, market, lease or sell during the term of
Executive's employment; or (iii) substantially similar to any technology or
service involving Clinical Decision Support of which the Executive had knowledge
at the time of the termination of the Executive's employment that the Company
was proposing to design, market, announce, lease or sell; PROVIDED, HOWEVER,
that the Executive may own any securities of a corporation which is engaged in
such business and is publicly owned and

                                      -9-
<PAGE>

traded but in amount not to exceed at any one time one percent (1%) of any class
of stock or securities of such company; PROVIDED FURTHER that Executive is not
personally engaged in any way, directly or indirectly, in any scientific or
business activity within such entity, which competes with the Company as
described above.

                           (b) during the Non-Competitive Period, request or
cause any suppliers or customers with whom the Company or any of its
subsidiaries has a business relationship to cancel or terminate any such
business relationship with the Company or any of its subsidiaries or solicit,
interfere with or entice from the Company any employee (or former employee) of
the Company;

                           (c) solicit, interfere with, hire, offer to hire,
persuade or induce any person who is or was an officer, employee, customer or
supplier of the Company or any of its subsidiaries or affiliates to discontinue
his relationship with the Company or any of its subsidiaries or affiliates or
accept employment by or enter into contractual relations for compensation with
any other entity or person, or approach any such employee of the Company or any
of its subsidiaries or affiliates for any such purpose or authorize or knowingly
approve the taking of any such actions by any other individual or entity. The
term "affiliate" shall mean any person or entity that directly or indirectly
through one or more intermediaries, controls or is controlled by, or is under
common control with, the Company.

         2. MISCELLANEOUS.

                  (a) The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement.

                  (b) This Agreement, together with the Employment Agreement,
supersedes all prior agreements, written or oral, between the Executive and the
Company relating to the subject matter of this Agreement. This Agreement may not
be modified, changed or discharged in whole or in part, except by an agreement
in writing signed by the Executive and the Company. The Executive agrees that
any change or changes in his/her duties, salary or compensation after the
signing of this Agreement shall not affect the validity or scope of this
Agreement.

                  (c) This Agreement will be binding upon the Executive's heirs,
executors and administrators and will inure to the benefit of the Company and
its successors and assigns.

                  (d) No delay or omission by either party in exercising any
right under this Agreement will operate as a waiver of that or any other right.
A waiver or consent given by either party on any one occasion is effective only
in that instance and will not be construed as a bar to or waiver of any right on
any other occasion.

                  (e) The Executive expressly consents to be bound by the
provisions of this Agreement for the benefit of the Company or any parent,
subsidiary or affiliate thereof to whose employ the Executive may be transferred
without the necessity that this Agreement be re-signed at the time of such
transfer.

                  (f) The restrictions contained in this Agreement are necessary
for the protection of the business and goodwill of the Company and are
considered by the Executive to be reasonable for such purpose. The Executive
agrees that any breach of this Agreement is likely to cause the Company
substantial and irrevocable damage and therefore, in the event of any such
breach, the Executive agrees that a remedy at law, in addition to such other
remedies which may be available, may be inadequate.

sealed instrument under and in accordance with the laws of the Commonwealth of
Pennsylvania. Any action, suit, or other legal proceeding which is commenced to
resolve any matter arising under or relating to any provision of this Agreement
shall be arbitrated or commenced in a court, as and to the extent set forth in
the Employment Agreement.

                  The Executive understands that nothing in this Agreement shall
otherwise affect the Executive's obligations under the Employment Agreement or
the Invention Assignment Agreement, each dated FEBRUARY 15, 1999 between the

       CARE MANAGEMENT SCIENCE CORPORATION INVENTION ASSIGNMENT AGREEMENT

                  Care Management Science Corporation, a Pennsylvania
corporation (the "Company") and Steven Bell ("Executive"), contemporaneously
with the execution of this Agreement are entering into an Employment Agreement
of even date herewith (the "Employment Agreement"), pursuant to which, among
other things, the Executive will be employed by the Company in the capacity of
its Chief Financial Officer. Capitalized terms used in this Agreement and not
otherwise defined herein shall have the meanings given such terms in the
Employment Agreement. In addition to the Company's desire to engage the
Executive and the Executive's desire to serve the Company, under the terms and
conditions of the Employment Agreement, the Executive understands that the
Company wishes to ensure all right, title and interest in and to any inventions
of Executive made during the term of his employment by the Company are and
remain the exclusive property of the Company.

                           In consideration for, and in order to induce my
employment by the Company, I hereby agree as follows:

         1. INVENTION ASSIGNMENT.

                  Whereas I will be participating in the preparation, writing,
creation, or development of certain business ideas, strategies, analyses,
reports, software, computer programs or other business activities collectively
referred to as the "Work";

                  (a) As an employee of the Company, any and all materials
created by me relating to the Work shall be considered as a "work made for
hire". Without limiting the foregoing, I hereby grant, transfer, assign, and
convey to the Company, its successors and assigns, the entire title, right,
interest, ownership and all subsidiary rights in and to the Work, all
intellectual property rights relating to the Work, and all copyrights, trade or
service marks, patents or other evidence of ownership and title pertaining to
the Work, including but not limited to the right to secure copyright, trade or
service mark or patent registration(s) in the Company' name as claimant and the
right to secure renewals, reissues, and extensions of any such filings in the
United States of America or any other country.

                  (b) I acknowledge that the Company, in its sole discretion,
shall determine whether copyright(s), trade or service mark(s) or patent
registration(s) in the Work shall be filed and/or preserved and maintained or
registered in the United States of America or any other country.

                  (c) I confirm that by this instrument, the Company and its
successors and assigns shall own the entire title, right and interest in and to
the Work, including the right to reproduce, display publicly, prepare derivative
Works from or distribute by sale, rental, lease lending or by other transfer of
ownership even if the Work does not constitute a "Work made for hire" as defined
in 17 U.S.C. Sections 101 and 201(b).

                  (d) I agree to take all actions and cooperate as is necessary
to protect the copyrights or other evidence of title in and to the Work and
further agree to execute any document(s) that may be necessary to perfect the
Company' ownership of copyrights, trade or service marks, patent(s) or other
evidence of ownership and title in the Work and the registration thereof,
without further compensation by the Company.

                  (e) I agree that all terms of this Agreement are applicable to
each portion or part of the Work, as well as to the Work in its entirety.

                  (f) Notwithstanding anything contained herein, the terms of
this Agreement shall not apply to any invention for which no equipment,
supplies, facility, time, proprietary or trade secret information of the Company
was used and which can be demonstrated was developed entirely on my own time, at
my own expense and which:(i) does not relate in any way to the business of the
Company or to the Company's actual or demonstrably anticipated expansion
research or development; and (ii) which does not result from any Work performed
by me for the Company.

         2. REPRESENTATIONS OF EXECUTIVE.

                  Executive represents and warrants that he is free to enter
into this Agreement and that there are no preceding claims or understandings,
restrictive covenants or other restrictions, whether written or oral, preventing
the performance of his duties hereunder.

         3. MISCELLANEOUS.

                  (a) The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement.

                  (b) This Agreement, together with the Employment and
Non-Competition Agreements, supersedes all prior agreements, written or oral,
between the Executive and the Company relating to the subject matter of this
Agreement. This Agreement may not be modified, changed or discharged in whole or
in part, except by an agreement in writing signed by the Executive and the
Company. The Executive agrees that any change or changes in his duties, salary
or compensation after the signing of this Agreement shall not affect the
validity or scope of this Agreement.

                  (c) This Agreement will be binding upon the Executive's heirs,
executors and administrators and will inure to the benefit of the Company and
its successors and assigns.

                  (d) No delay or omission by either party in exercising any
right under this Agreement will operate as a waiver of that or any other right.
A waiver or consent given by either party on any one occasion is effective only
in that instance and will not be construed as a bar to or waiver of any right on
any other occasion.

                  (e) The Executive expressly consents to be bound by the
provisions of this

                                      -13-

Agreement for the benefit of the Company or any parent, subsidiary or affiliate
thereof to whose employ the Executive may be transferred without the necessity
that this Agreement be re-signed at the time of such transfer.

for the protection of the Company and are considered by the Executive to be
reasonable for such purpose. The Executive agrees that any breach of this
Agreement is likely to cause the Company substantial and irrevocable damage and
therefore, in the event of any such breach, the Executive agrees that a remedy
at law, in addition to such other remedies which may be available, may be
inadequate.

                               AGREEMENT REGARDING
                                CHANGE IN CONTROL

         THIS AGREEMENT ("Agreement"), made and entered into as of the 1st day
of January, 2000 (the "Effective Date"), by and between Abbott Laboratories (the
"Company") and __________ (the "Executive");

                                WITNESSETH THAT:

         WHEREAS, the Company considers it essential to the best interests of
its shareholders to foster the continuous employment of key management
personnel, and the Board of Directors of the Company (the "Board") recognizes
that, as is the case with many publicly held corporations, a change in control
might occur and that such possibility, and the uncertainty and questions which
it may raise among management, may result in the departure or distraction of
management personnel to the detriment of the Company and its shareholders; and

         WHEREAS, the Board has determined that appropriate steps should be
taken to reinforce and encourage the continued attention and dedication of
members of the Company's management, including the Executive, to their assigned
duties without distraction in the face of potentially disturbing circumstances
arising from the possibility of a change in control of the Company;

         NOW, THEREFORE, to induce the Executive to remain in the employ of the
Company and in consideration of the premises and mutual covenants set forth
herein, IT IS HEREBY AGREED by and between the parties as follows:

         1. AGREEMENT TERM. The initial "Agreement Term" shall begin on the
Effective Date and shall continue through December 31, 2002. As of December 31,
2000, and as of each December 31 thereafter, the Agreement Term shall extend
automatically to the third anniversary thereof unless the Company gives notice
to the Executive prior to the date of such extension that the Agreement Term
will not be extended. Notwithstanding the foregoing, if a Change in Control (as
defined in Section 7 below), occurs during the Agreement Term, the Agreement
Term shall continue through and terminate on the second anniversary of the date
on which the Change in Control occurs.

         2. ENTITLEMENT TO CHANGE IN CONTROL BENEFITS. The Executive shall be
entitled to the Change in Control Benefits described in Section 3 hereof if the
Executive's employment by the Company is terminated during the Agreement Term
but after a Change in Control (i) by the Company for any reason other than
Permanent Disability or Cause, or (ii) by the Executive for Good Reason. For
purposes of this Agreement:

<PAGE>

(a)      A termination of the Executive's employment shall be treated as a
         termination by reason of "Permanent Disability" only if, due to a
         mental or physical disability, the Executive is absent from the full
         time performance of duties with the Company for a period of at least
         twelve consecutive months and fails to return to the full time
         performance of duties within 30 days after receipt of a demand by the
         Company to do so.

(b)      The term "Cause" shall mean the willful engaging by the Executive in
         illegal conduct or gross misconduct which is demonstrably and
         materially injurious to the Company. For purposes of this Agreement, no
         act, or failure to act, on the Executive's part shall be deemed
         "willful" unless done, or omitted to be done, by the Executive not in
         good faith and without reasonable belief that the Executive's action or
         omission was in the best interest of the Company. Notwithstanding the
         foregoing, the Executive shall not be deemed to have been terminated
         for Cause unless and until the Company delivers to the Executive a copy
         of a resolution duly adopted by the affirmative vote of not less than
         three-quarters of the entire membership of the Board at a meeting of
         the Board called and held for such purpose (after reasonable notice to
         the Executive and an opportunity for the Executive, together with
         counsel, to be heard before the Board) finding that, in the good faith
         opinion of the Board, the Executive was guilty of conduct set forth
         above and specifying the particulars thereof in detail.

(c)      The term "Good Reason" shall mean the occurrence of any of the
         following circumstances without the Executive's express written
         consent:

         (i)      a significant adverse change in the nature, scope or status of
                  the Executive's position, authorities or duties from those in
                  effect immediately prior to the Change in Control;

         (ii)     the failure by the Company to pay the Executive any portion of
                  the Executive's current compensation, or to pay the Executive
                  any portion of any installment of deferred compensation under
                  any deferred compensation program of the Company, within seven
                  days of the date such compensation is due;

         (iii)    a reduction in the Executive's annual base salary (or a
                  material change in the frequency of payment) as in effect
                  immediately prior to the Change in Control as the same may be
                  increased from time to time;

         (iv)     the failure by the Company to award the Executive an annual
                  bonus in any year which is at least equal to the annual bonus,
                  awarded to the Executive under the annual bonus plan of the
                  Company for the year immediately preceding the year of the
                  Change in Control;

         (v)      the failure by the Company to award the Executive equity-based
                  incentive compensation (such as stock options, shares of
                  restricted stock, or other equity-

                                                   2

                  based compensation) on a periodic basis consistent with the
                  Company's practices with respect to timing, value and terms
                  prior to the Change in Control;

         (vi)     the failure by the Company to continue to provide the
                  Executive with the welfare benefits, fringe benefits and
                  perquisites enjoyed by the Executive immediately prior to the
                  Change in Control under any of the Company's plans or
                  policies, including, but not limited to, those plans and
                  policies providing pension, life insurance, medical, health
                  and accident, disability, vacation, executive automobile,
                  executive tax or financial advice benefits or club dues;

         (vii)    the relocation of the Company's principal executive offices to
                  a location more than thirty-five miles from the location of
                  such offices immediately prior to the Change in Control or the
                  Company requiring the Executive to be based anywhere other
                  than the Company's principal executive offices except for
                  required travel to the Company's business to an extent
                  substantially consistent with the Executive's business travel
                  obligations immediately prior to the Change in Control; or

         (viii)   the failure of the Company to obtain a satisfactory agreement
                  from any successor to the Company to assume and agree to
                  perform this Agreement as contemplated by Section 16.

         3. CHANGE IN CONTROL BENEFITS. In the event of a termination of
employment entitling the Executive to benefits in accordance with Section 2, the
Executive shall receive the following:

(a)      The Executive shall be entitled to receive the following employee
         welfare benefits: medical, accident, dental, prescription, and life
         insurance coverage for the Executive (and, where applicable under the
         Company's welfare benefit plans, the Executive's family) through the
         third anniversary of the Executive's date of termination of employment,
         or, if earlier, the date on which the Executive becomes employed by
         another employer. The benefits provided by the Company shall be no less
         favorable in terms of coverage and cost to the Executive than those
         provided under the Company's welfare benefit plans applicable to the
         Executive (and, where applicable, the Executive's family) prior to the
         Change in Control, determined as if the Executive remained in the
         employ of the Company through such third anniversary. For purposes of
         determining eligibility of the Executive for retiree welfare benefits,
         the Executive shall be considered to have remained in the employ of the
         Company through such third anniversary.

(b)      If the Executive's date of termination occurs after the end of a
         performance period applicable to an annual incentive (bonus) award,
         and prior to the payment of the award for the period, the Executive
         shall be entitled to a lump sum payment in cash no later than twenty
         (20) business days after the date of termination equal to the
         greatest of (i) the Executive's annual incentive (bonus) award for
         that period, as determined under the terms of that incentive award
         arrangement, (ii) the Executive's annual incentive (bonus) award for
         that period, with the determination of the amount of such award
         based on an

                                           3

<PAGE>

         assumption that the target level of performance had been achieved or
         (iii) the Participant's average annual incentive (bonus) award for
         the three annual performance periods preceding that period (provided
         that if the Participant was not a participant in the incentive award
         arrangement for any of those three prior years, the averaging period
         shall be reduced from three years to the number of years during the
         three year period in which the Participant was a participant; and
         further provided that if the Participant's award for any such year
         was reduced because the Participant was not a participant for the
         full year, such amount shall be annualized for purposes of the
         computation in this clause (iii)).

(c)      For any annual incentive (bonus) plan or arrangement in which the
         Executive participates for the performance period in which the
         Executive's termination of employment occurs, the Executive shall be
         entitled to a lump sum payment in cash no later than twenty
         (20) business days after the date of termination equal to the greater
         of (i) the Executive's annual incentive (bonus) award for the
         performance period that includes the date of termination, with the
         determination of the amount of such award based on an assumption
         that the target level of performance has been achieved or (ii) the
         Executive's average annual incentive (bonus) award for the three
         annual performance periods preceding the performance period that
         includes the date of termination (provided that if the Executive was
         not a participant in the incentive award arrangement for any of
         those three prior years, the averaging period shall be reduced from
         three years to the number of years during the three year period in
         which the Executive was a participant; and further provided that if
         the Executive's award for any such year was reduced because the
         Executive was not a participant for the full year, such amount shall
         be annualized for purposes of the computation in this clause (ii));
         provided that such payment shall be subject to a pro-rata reduction
         to reflect the number of days in the performance period following
         the date of termination. The amount payable under this paragraph (c)
         shall be in lieu of any amounts that may otherwise be due to the
         Executive with respect to any annual incentive (bonus) plan or
         arrangement in which the Executive participates for the performance
         period in which the Executive's date of termination occurs.

(d)      The Executive shall be entitled to a lump sum payment in cash no later
         than twenty business days after the Executive's date of termination
         equal to the sum of:

         (i)      an amount equal to three times the Executive's annual salary
                  rate in effect on the date of the Change in Control or, or if
                  greater, as in effect immediately prior to the date of
                  termination; plus

         (ii)     an amount equal to three times the greater of (x) the
                  Executive's annual incentive (bonus) award for the
                  performance period that includes the date of the
                  Executive's termination of employment, with the
                  determination of the amount of such award based on an
                  assumption that the target level of performance has been
                  achieved or (y) the Executive's average annual incentive
                  (bonus) award for the three annual performance periods
                  preceding the performance period that includes the date of
                  termination (provided that if the Executive was not a
                  participant in the incentive

                                                4

<PAGE>

                  award arrangement for any of those three prior years, the
                  averaging period shall be reduced from three years to the
                  number of years during the three year period in which the
                  Executive was a participant; and further provided that if
                  the Executive's award for any such year was reduced because
                  the Executive was not a participant for the full year, such
                  amount shall be annualized for purposes of the computation
                  in this subparagraph (ii)).

         The amount payable under this paragraph (d) shall be inclusive of the
         amounts, if any, to which the Executive would otherwise be entitled as
         severance pay under any severance pay plan, or by law and shall be in
         addition to (and not inclusive of) any amount payable under any written
         agreement(s) directly between the Executive and the Company or any of
         its subsidiaries.

(e)      The Executive shall be entitled to benefits under the Abbott
         Laboratories Supplemental Pension Plan (the "Supplemental Plan") which
         shall be determined as if the Executive had been credited for benefit
         accrual purposes with three additional years of service and three
         additional years of eligible earnings at the higher of the Executive's
         eligible earnings on the date of termination or the Executive's
         eligible earnings on the date of the Change in Control and, for
         purposes of determining the Executive's eligibility for subsidized
         early retirement benefits, determined as if the Executive were three
         years older than the Executive's actual age on the date of termination.
         For purposes of this paragraph (e), "eligible earnings" shall include
         salary, annual incentive (bonus) awards and all other forms of
         compensation used to calculate benefits under the Supplemental Plan.
         The amounts of the annual incentive (bonus) awards shall be calculated
         in accordance with this paragraph (e) and, to the extent applicable,
         paragraphs (b) and (c) above. The Executive's benefits under the
         Supplemental Plan shall be determined, paid and administered without
         regard to any termination or amendment (including any amendment
         affecting actuarial factors) of such plan or of any other plan, which
         is adopted on or after a Change in Control or in contemplation of a
         Change in Control and, subject to paragraph (f) below, shall be paid in
         accordance with the terms of that plan and the Executive's elections
         under that plan. Within twenty (20) days of Executive's date of
         termination, the Company shall provide the Executive with all forms,
         elections and materials required in connection with the funding or
         payment of the Executive's benefits under that plan. Within twenty
         (20) days of the Company's receipt of properly executed and completed
         forms, elections and other required materials from the Executive, the
         Company shall fund the additional benefits to the extent provided by
         the terms of such plan.

(f)      The Executive shall be entitled to elect that all or any portion of the
         amounts payable under paragraphs 3(b) and 3(c) and subparagraph
         3(d)(ii) above (less applicable tax withholding) be paid directly to a
         grantor trust established by the Executive to the same extent as
         bonuses payable under the 1986 Abbott Laboratories Management Incentive
         Plan, the 1998 Abbott Laboratories Performance Incentive Plan, or any
         successor plans thereto with all of the rights and entitlements
         attendant thereto.

If the Executive is a participant in the 1998 Abbott Laboratories Performance
Incentive Plan or any successor thereto, the Executive's annual incentive
(bonus) award for the performance period which includes the date of termination
under paragraphs (c) and (d)(ii) above and, if applicable, for the period
preceding the date of termination under paragraph (b) shall, be determined under
the bonus levels communicated in writing to the Executive by the Company for
such year and shall not be the Executive's individual base award allocation as
defined in Section 4.2 of the 1998 Abbott Laboratories Performance Incentive
Plan (or any corresponding provision of any successor plan).

         4. MITIGATION. The Executive shall not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise. Except as set forth in paragraph 3(a) with respect to benefits,
the Company shall not be entitled to set off against the amounts payable to the
Executive under this Agreement any amounts owed to the Company by the Executive,
any amounts earned by the Executive in other employment after the Executive's
termination of employment with the Company, or any amounts which might have been
earned by the Executive in other employment had the Executive sought such other
employment.

         5. MAKE-WHOLE PAYMENTS. If any payment or benefit to which the
Executive (or any person on account of the Executive) is entitled, whether under
this Agreement or otherwise, in connection with a Change in Control or the
Executive's termination of employment (a "Payment") constitutes a "parachute
payment" within the meaning of section 280G of the Internal Revenue Code of
1986, as amended (the "Code"), and as a result thereof the Executive is subject
to a tax under section 4999 of the Code, or any successor thereto, (an "Excise
Tax"), the Company shall pay to the Executive an additional amount (the
"Make-Whole Amount") which is intended to make the Executive whole for such
Excise Tax, other than the portion thereof that is attributable solely to
equity-based compensation. The Make-Whole Amount shall be equal to (x) minus
(y) where (x) is equal to (i) the amount of the Excise Tax, plus (ii) the
aggregate amount of any interest, penalties, fines or additions to any tax
which are imposed in connection with the imposition of such Excise Tax, plus
(iii) all income, excise and other applicable taxes imposed on the Executive
under the laws of any Federal, state or local government or taxing authority
by reason of the payments required under clauses (i) and (ii) and this clause
(iii), and (y) is the amount that would be determined under such clauses (i),
(ii), and (iii) if the only parachute payments received by the Executive were
equity-based Payments, including but not limited to the accelerated vesting
of stock options, shares of restricted stock, or any other equity based award.

(a)     For purposes of determining the Make-Whole Amount, the Executive shall
        be deemed to be taxed at the highest marginal rate under all applicable
        local, state, federal and foreign income tax laws for the year in which
        the Make-Whole Amount is paid. The Make-Whole Amount payable with
        respect to an Excise Tax shall be paid by the Company coincident with
        the Payment with respect to which such Excise Tax relates.

                                         6

(b)     All calculations under this Section 5 shall be made initially by the
        Company and the Company shall provide prompt written notice thereof to
        the Executive to enable the Executive to timely file all applicable tax
        returns. Upon request of the Executive, the Company shall provide the
        Executive with sufficient tax and compensation data to enable the
        Executive or the Executive's tax advisor to independently make the
        calculations described in subparagraph (a) above and the Company shall
        reimburse the Executive for reasonable fees and expenses incurred for
        any such verification.

(c)     If the Executive gives written notice to the Company of any objection
        to the results of the Company's calculations within 60 days of the
        Executive's receipt of written notice thereof, the dispute shall be
        referred for determination to independent tax counsel selected by the
        Company and reasonably acceptable to the Executive ("Tax Counsel"). The
        Company shall pay all fees and expenses of such Tax Counsel. Pending
        such determination by Tax Counsel, the Company shall pay the Executive
        the Make-Whole Amount as determined by it in good faith. The Company
        shall pay the Executive any additional amount determined by Tax Counsel
        to be due under this Section 5 (together with interest thereon at a
        rate equal to 120% of the Federal short-term rate determined under
        section 1274(d) of the Code) promptly after such determination.

(d)     The determination by Tax Counsel shall be conclusive and binding upon
        all parties unless the Internal Revenue Service, a court of competent
        jurisdiction, or such other duly empowered governmental body or agency
        (a "Tax Authority") determines that the Executive owes a greater or
        lesser amount of Excise Tax with respect to any Payment than the amount
        determined by Tax Counsel.

(e)     If a Taxing Authority makes a claim against the Executive which, if
        successful, would require the Company to make a payment under this
        Section 5, the Executive agrees to contest the claim with counsel
        reasonably satisfactory to the Company, on request of the Company
        subject to the following conditions:

        (i)      The Executive shall notify the Company of any such claim
                 within 10 days of becoming aware thereof. In the event that
                 the Company desires the claim to be contested, it shall
                 promptly (but in no event more than 30 days after the
                 notice from the Executive or such shorter time as the
                 Taxing Authority may specify for responding to such claim)
                 request the Executive to contest the claim. The Executive
                 shall not make any payment of any tax which is the subject
                 of the claim before the Executive has given the notice or
                 during the 30-day period thereafter unless the Executive
                 receives written instructions from the Company to make such
                 payment together with an advance of funds sufficient to
                 make the requested payment plus any amounts payable under
                 this Section 5 determined as if such advance were an Excise
                 Tax, in which case the Executive will act promptly in
                 accordance with such instructions.

                                               7
<PAGE>

         (ii)     If the Company so requests, the Executive will contest the
                  claim by either paying the tax claimed and suing for a refund
                  in the appropriate court or contesting the claim in the United
                  States Tax Court or other appropriate court, as directed by
                  the Company; PROVIDED, HOWEVER, that any request by the
                  Company for the Executive to pay the tax shall be accompanied
                  by an advance from the Company to the Executive of funds
                  sufficient to make the requested payment plus any amounts
                  payable under this Section 5 determined as if such advance
                  were an Excise Tax. If directed by the Company in writing the
                  Executive will take all action necessary to compromise or
                  settle the claim, but in no event will the Executive
                  compromise or settle the claim or cease to contest the claim
                  without the written consent of the Company; PROVIDED, HOWEVER,
                  that the Executive may take any such action if the Executive
                  waives in writing the Executive's right to a payment under
                  this Section 5 for any amounts payable in connection with such
                  claim. The Executive agrees to cooperate in good faith with
                  the Company in contesting the claim and to comply with any
                  reasonable request from the Company concerning the contest of
                  the claim, including the pursuit of administrative remedies,
                  the appropriate forum for any judicial proceedings, and the
                  legal basis for contesting the claim. Upon request of the
                  Company, the Executive shall take appropriate appeals of any
                  judgment or decision that would require the Company to make a
                  payment under this Section 5. Provided that the Executive is
                  in compliance with the provisions of this section, the Company
                  shall be liable for and indemnify the Executive against any
                  loss in connection with, and all costs and expenses, including
                  attorneys' fees, which may be incurred as a result of,
                  contesting the claim, and shall provide to the Executive
                  within 30 days after each written request therefor by the
                  Executive cash advances or reimbursement for all such costs
                  and expenses actually incurred or reasonably expected to be
                  incurred by the Executive as a result of contesting the claim.

(f)      Should a Tax Authority finally determine that an additional Excise Tax
         is owed, then the Company shall pay an additional Make-Whole Amount to
         the Executive in a manner consistent with this Section 5 with respect
         to any additional Excise Tax and any assessed interest, fines, or
         penalties. If any Excise Tax as calculated by the Company or Tax
         Counsel, as the case may be, is finally determined by a Tax Authority
         to exceed the amount required to be paid under applicable law, then the
         Executive shall repay such excess to the Company within 30 days of such
         determination; provided that such repayment shall be reduced by the
         amount of any taxes paid by the Executive on such excess which is not
         offset by the tax benefit attributable to the repayment.

         6. TERMINATION DURING POTENTIAL CHANGE IN CONTROL. If a Potential
Change in Control (as defined in Section 8) occurs during the Agreement Term,
and the Company terminates the Executive's employment for reasons other than
Permanent Disability or Cause during such Potential Change in Control, the
Executive shall be entitled to receive the benefits that the Executive would
have received under Section 3, such benefits to be calculated based upon the

                                         8
<PAGE>

Executive's compensation prior to the actual termination of employment but paid
within 20 business days of the date of such termination.

         7. CHANGE IN CONTROL. For purposes of this Agreement, a "Change in
Control" shall be deemed to have occurred on the earliest of the following
dates:

(a)      the date any entity or person (including a "group" as defined in
         Section 13(d)(3) of the Securities Exchange Act of 1934 (the "Exchange
         Act")) shall have become the beneficial owner of, or shall have
         obtained voting control over, twenty percent (20%) or more of the
         outstanding common shares of the Company;

(b)      the date on which the Company (i) merges or consolidates with or into
         another corporation, or merges another corporation into the Company, in
         which the Company is not the continuing or surviving corporation or
         pursuant to which any common shares of the Company are converted into
         cash, securities of another corporation, or other property, other than
         a merger or consolidation of the Company in which holders of common
         shares immediately prior to the merger have the same proportionate
         ownership of common stock of the surviving corporation or its parent
         corporation immediately after the merger as immediately before, or
         (ii) sells or otherwise disposes of substantially all of the assets
         of the Company; or

(c)      the date there shall have been a change in a majority of the Board of
         Directors of the Company within a twelve (12) month period unless the
         nomination for election by the Company's shareholders of each new
         director was approved by the vote of two-thirds of the directors then
         still in office who were in office at the beginning of the twelve (12)
         month period.

         8. POTENTIAL CHANGE IN CONTROL. A "Potential Change in Control" shall
exist during any period in which the circumstances described in paragraphs (a),
(b), (c) or (d), below, exist (provided, however, that a Potential Change in
Control shall cease to exist not later than the occurrence of a Change in
Control):

(a)      The Company enters into an agreement, the consummation of which would
         result in the occurrence of a Change in Control, provided that a
         Potential Change in Control described in this paragraph (a) shall cease
         to exist upon the expiration or other termination of all such
         agreements.

(b)      Any person (including the Company) publicly announces an intention
         to take or to consider taking actions the consummation of which
         would constitute a Change in Control; provided that a Potential
         Change in Control described in this paragraph (b) shall cease to
         exist upon the withdrawal of such intention, or upon a reasonable
         determination by the Board that there is no reasonable chance that
         such actions would be consummated.

                                             9

<PAGE>

(c)      The acquisition by any person (within the meaning of Section 13(d)(3)
         or 14(d)(2) of the Securities Exchange Act of 1934) of beneficial
         ownership of 10 percent or more of the then outstanding shares of
         common stock of the Company; but excluding, for this purpose, any such
         acquisition by:

         (i)    the Company, any subsidiary, any employee benefit plan (or
                related trust, or a fiduciary of the plan or trust) maintained
                by the Company or any Subsidiary, or any person who satisfies
                the requirements set forth in Rule 13d-1(b)(1)(i) and (ii)
                promulgated under the Securities Exchange Act of 1934; or

         (ii)   any corporation with respect to which, following such
                acquisition, more than 50 percent of the then outstanding
                shares of common stock of such corporation is then
                beneficially owned by all or substantially all of the
                individuals and entities who were the beneficial owners of
                common stock of the Company immediately prior to such
                acquisition, and in substantially the same proportion as their
                ownership, immediately prior to such acquisition, of the then
                outstanding shares of common stock of the Company.

(d)      The Board adopts a resolution to the effect that, for purposes of this
         Agreement, a Potential Change in Control exists; provided that a
         Potential Change in Control described in this paragraph (d) shall cease
         to exist upon a reasonable determination by the Board that the reasons
         that gave rise to the resolution providing for the existence of a
         Potential Change in Control have expired or no longer exist.

         9. STOCK AND OPTION AWARDS. With respect to any award granted the
Executive after the date of execution of this Agreement (and not the
Effective Date) under the Company's 1996 Incentive Stock Program or any
successor thereto that includes a provision substantially similar to the
provision contained on Appendix A, after a Change in Control no forfeiture
shall be effected pursuant to such provision unless the Executive shall have
been terminated for "Cause" pursuant to the provisions of paragraph 2(b)
above.

         10. WITHHOLDING. All payments to the Executive under this Agreement
will be subject to withholding of applicable taxes. The Company shall
withhold the applicable taxes in an amount calculated at the minimum
statutory rate and shall pay the amount so withheld to the appropriate tax
authority.

         11. NONALIENATION. The interests of the Executive under this
Agreement are not subject in any manner to anticipation, alienation, sale,
transfer, assignment, pledge, encumbrance, attachment, or garnishment by
creditors of the Executive or the Executive's beneficiary.

         12. AMENDMENT. This Agreement may be amended or canceled only by
mutual agreement of the parties in writing without the consent of any other
person. So long as the Executive lives, no person, other than the parties
hereto, shall have any rights under or interest in this Agreement or the
subject matter hereof.

                                       10
<PAGE>

         13. APPLICABLE LAW. The provisions of this Agreement shall be
construed in accordance with the laws of the State of Illinois, without
regard to the conflict of law provisions of any state.

         14. SEVERABILITY. The invalidity or unenforceability of any
provision of this Agreement will not affect the validity or enforceability of
any other provision of this Agreement, and this Agreement will be construed
as if such invalid or unenforceable provision were omitted (but only to the
extent that such provision cannot be appropriately reformed or modified).

         15. WAIVER OF BREACH. No waiver by any party hereto of a breach of
any provision of this Agreement by any other party, or of compliance with any
condition or provision of this Agreement to be performed by such other party,
will operate or be construed as a waiver of any subsequent breach by such
other party of any similar or dissimilar provisions and conditions at the
same or any prior or subsequent time. The failure of any party hereto to take
any action by reason of such breach will not deprive such party of the right
to take action at any time while such breach continues.

         16. SUCCESSORS, ASSUMPTION OF CONTRACT. This Agreement shall be
binding upon and inure to the benefit of the Company and any successor of the
Company. The Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all
of the business and/or assets of the Company to expressly assume and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no succession had taken place.
This Agreement is personal to the Executive and may not be assigned by the
Executive without the written consent of the Company. However, to the extent
that rights or benefits under this Agreement otherwise survive the
Executive's death, the Executive's heirs and estate shall succeed to such
rights and benefits pursuant to the Executive's will or the laws of descent
and distribution; provided that the Executive shall have the right at any
time and from time to time, by notice delivered to the Company, to designate
or to change the beneficiary or beneficiaries with respect to such benefits.

         17. NOTICES. Notices and all other communications provided for in
this Agreement shall be in writing and shall be delivered personally or sent
by registered or certified mail, return receipt requested, postage prepaid
(provided that international mail shall be sent via overnight or two-day

alternative dispute resolution procedures in accordance with Appendix B hereto.

         19. LEGAL AND ENFORCEMENT COSTS. The provisions of this Section 19

<PAGE>

(c)      The Executive shall be entitled to select legal counsel; provided,
         however, that such right of selection shall not affect the requirement
         that any costs and expenses reimbursable under this Section 19 be
         reasonable.

(d)      The Executive's rights to payments under this Section 19 shall not be

this Agreement, the rights and obligations of the parties to this Agreement
shall survive the termination of the Executive's employment with the Company.

Agreement constitutes the entire agreement between the parties concerning the
subject matter hereof and supersedes all prior or contemporaneous agreements,
if any, between the parties relating to the subject matter hereof; provided,
however, that nothing in this Agreement shall be construed to limit any
policy or agreement that is otherwise applicable relating to confidentiality,
rights to inventions, copyrightable material, business and/or technical
information, trade secrets, solicitation of employees, interference with
relationships with other businesses, competition, and other similar policies
or agreement for the protection of the business and operations of the Company
and the subsidiaries.

         22. COUNTERPARTS. This Agreement may be executed in two or more
counterparts, any one of which shall be deemed the original without reference
to the others.

         IN WITNESS THEREOF, the Executive has hereunto set his hand, and the
Company has caused these presents to be executed in its name and on its behalf,
and its corporate seal to be hereunto affixed on this ____ day of _____________,
2000, all as of the Effective Date.

                     AGREEMENT REGARDING CHANGE IN CONTROL
                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES

The parties to the Agreement Regarding Change in Control dated as of the 1st
day of January, 2000 (the "Agreement") recognize that a bona fide dispute as
to certain matters may arise from time to time during the term of the
Agreement which relates to either party's rights and/or obligations. To have
such a dispute resolved by this Alternative Dispute Resolution ("ADR")
provision, a party first must send written notice of the dispute to the other
party for attempted resolution by good faith negotiations between the
Executive and the Company within twenty-eight (28) days after such notice is
received (all references to "days" in the ADR provision are to calendar days).

If the matter has not been resolved within twenty-eight (28) days of the
notice of dispute, or if the parties fail to meet within such twenty-eight
(28) days, either party may initiate an ADR proceeding as provided herein.
The parties shall have the right to be represented by counsel in such a
proceeding.

1.   To begin an ADR proceeding, a party shall provide written notice to the
     other party of the issues to be resolved by ADR. Within fourteen
     (14) days after its receipt of such notice, the other party may, by
     written notice to the party initiating the ADR, add additional issues to
     be resolved within the same ADR.

2.   Within twenty-one (21) days following receipt of the original ADR
     notice, the parties shall select a mutually acceptable neutral to
     preside in the resolution of any disputes in this ADR proceeding. If
     the parties are unable to agree on a mutually acceptable neutral within
     such period, either party may request the President of the CPR
     Institute for Dispute Resolution ("CPR"), 366 Madison Avenue, 14th
     Floor, New York, New York 10017, to select a neutral pursuant to the
     following procedures:

     (a)      The CPR shall submit to the parties a list of not less than
              five (5) candidates within fourteen (14) days after receipt of
              the request, along with a CURRICULUM VITAE for each candidate.
              No candidate shall be an employee, director or shareholder of
              either party or any of their subsidiaries or affiliates.

     (b)      Such list shall include a statement of disclosure by each
              candidate of any circumstances likely to affect his or her
              impartiality.

     (c)      Each party shall number the candidates in order of preference
              (with the number one (1) signifying the greatest preference)
              and shall deliver the list to the CPR within seven (7) days
              following receipt of the list of candidates. If a party

                                       15
<PAGE>

              believes a conflict of interest exists regarding any of the
              candidates, that party shall provide a written explanation of
              the conflict to the CPR along with its list showing its order
              of preference for the candidates. Any party failing to return
              a list of preferences on time shall be deemed to have no order
              of preference.

     (d)      If the parties collectively have identified fewer than three
              (3) candidates deemed to have conflicts, the CPR immediately
              shall designate as the neutral the candidate for whom the
              parties collectively have indicated the greatest preference.
              If a tie should result between two candidates, the CPR may
              designate either candidate. If the parties collectively have
              identified three (3) or more candidates deemed to have
              conflicts, the CPR shall review the explanations regarding
              conflicts and, in its sole discretion, may either
              (i) immediately designate as the neutral the candidate for
              whom the parties collectively have indicated the greatest
              preference, or (ii) issue a new list of not less than five
              (5) candidates, in which case the procedures set forth in
              subparagraphs 2(a)-2(d) shall be repeated.

3.    No earlier than twenty-eight (28) days or later than fifty-six
      (56) days after selection, the neutral shall hold a hearing to resolve
      each of the issues identified by the parties. The ADR proceeding shall
      take place at a location agreed upon by the parties. If the parties
      cannot agree, the neutral shall designate a location other than the
      principal place of business of either party or any of the subsidiaries
      or affiliates.

4.    At least seven (7) days prior to the hearing, each party shall submit
      the following to the other party and the neutral:

      (a)      a copy of all exhibits on which such party intends to rely in
               any oral or written presentation to the neutral;

      (b)      a list of any witnesses such party intends to call at the
               hearing, and a short summary of the anticipated testimony of
               each witness;

      (c)      a proposed ruling on each issue to be resolved, together with
               a request for a specific damage award or other remedy for each
               issue. The proposed rulings and remedies shall not contain any
               recitation of the facts or any legal arguments and shall not
               exceed one (1) page per issue.

      (d)      a brief in support of such party's proposed rulings and
               remedies, provided that the brief shall not exceed twenty
               (20) pages. This page limitation shall apply regardless of the
               number of issues raised in the ADR proceeding.

      Except as expressly set forth in subparagraphs 4(a) - 4(d), no
      discovery shall be required or permitted by any means, including
      deposition, interrogatories, requests for admissions or production of
      documents.

                                        16

5.    The hearing shall be conducted on two (2) consecutive days and shall be
      governed by the following rules:

      (a)    Each party shall be entitled to five (5) hours of hearing time
             to present its case. The neutral shall determine whether each
             party has had the five (5) hours to which it is entitled.

      (b)    Each party shall be entitled, but not required, to make an
             opening statement, to present regular or rebuttal testimony,
             documents or other evidence, to cross-examine witnesses and to
             make a closing argument. Cross-examination of witnesses shall
             occur immediately after their direct testimony, and
             cross-examination time shall be charged against the party
             conducting the cross-examination.

      (c)    The party initiating the ADR shall begin the hearing and, if
             it chooses to make an opening statement, shall address not
             only issues it raised, but also any issues raised by the
             responding party. The responding party, if it chooses to make
             an opening statement, also shall address all issues raised in
             the ADR. Thereafter, the presentation of regular and rebuttal
             testimony and documents, other evidence and closing arguments
             shall proceed in the same sequence.

      (d)    Except when testifying, witnesses shall be excluded from the
             hearing until closing arguments.

      (e)    Settlement negotiations, including any statements made
             therein, shall not be admissible under any circumstances.
             Affidavits prepared for purposes of the ADR hearing also shall
             not be admissible. As to all other matters, the neutral shall
             have sole discretion regarding the admissibility of any
             evidence.

6.    Within seven (7) days following completion of the hearing, each party
      may submit to the other party and the neutral a post-hearing brief in
      support of its proposed rulings and remedies, provided that such brief
      shall not contain or discuss any new evidence and shall not exceed ten
      (10) pages. This page limitation shall apply regardless of the number
      of issues raised in the ADR proceeding.

7.    The neutral shall rule on each disputed issue within fourteen (14) days
      following completion of the hearing. Such ruling shall adopt in its
      entirety the proposed ruling and remedy of one of the parties on each
      disputed issue but may adopt one party's proposed rulings and remedies
      on some issues and the other party's proposed rulings and remedies on
      other issues. The neutral shall not issue any written opinion or
      otherwise explain the basis of the ruling.

                                     17

8.       The neutral shall be paid a reasonable fee plus expenses by the
         Company. The Company shall bear its own fees and expenses. The
         Executive's fees and expenses shall be paid or reimbursed by the
         Company to the extent provided by the Agreement.

9.       The rulings of the neutral and the allocation of fees and expenses
         shall be binding, non-reviewable, and non-appealable, and may be
         entered as a final judgment in any court having jurisdiction.

10.      Except as provided in Section 9 or as required by law, the existence of
         the dispute, any settlement negotiations, the ADR hearing, any
         submissions (including exhibits, testimony, proposed rulings, and
         briefs), and the rulings shall be deemed Confidential Information. The
         neutral shall have the authority to impose sanctions for unauthorized
         disclosure of Confidential Information.
