          AGREEMENT made as of the 1st day of August, 1993 by and between J. P.
BOLDUC, residing at 3000 South Ocean Boulevard, Boca Raton, Florida
("Employee"), and W. R. GRACE & CO., a New York corporation (the "Company").

          WHEREAS, the Company has employed Employee and desires to continue to

Company in such capacity on the terms and conditions hereinafter provided;

          WHEREAS, Employee is a key senior executive of the Company with major
responsibilities for planning, directing, coordinating and controlling overall
corporate operations;

          WHEREAS, in such capacity Employee will develop or have access to all
of the business methods and confidential information relating to the Company,
including, but not limited to, its financial performance and results, its
manufacturing organization and methods, its research and development of
products, its service techniques, its purchasing organization and methods, its
sales organization and methods, its inventories, its market development and
expansion plans, its personnel training and development programs, and its
customer and supplier relationships;

          WHEREAS, a subsidiary of the Company and Employee heretofore entered
in an Employment Agreement dated as of August 1, 1987, which Employment
Agreement was subsequently



                                       -2-


assigned to the Company and amended (such Employment Agreement, as so assigned
and amended, being hereinafter referred to as the "1987 Employment Agreement");

          WHEREAS, the Company and Employee now desire to further amend and to
restate the 1987 Employment Agreement to take the form of this Agreement;

          NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein contained, the parties hereto agree as follows:

                              I.  EMPLOYMENT

     SECTION 1.1     POSITIONS AND DUTIES.

          (a)  The Company shall employ Employee, and Employee shall work for
the Company, as Chief Executive Officer, and he shall report directly to the
Board of Directors of the Company. Employee shall have such duties and authority
as are specified in the Company's By-laws and otherwise normally associated with
his office.  While employed hereunder, Employee shall devote his full time,
effort, skill and attention to the affairs of the Company. During the term of
his employment hereunder, Employee shall not render any services to any other
person that might be in competition with the Company or any of its subsidiaries
or affiliates or in conflict with his position as a senior executive of the
Company or his duty of undivided loyalty to the Company.



                                       -3-


          (b)  While employed hereunder, Employee will be nominated as a
management nominee for election as a director of the Company and will continue
to be nominated after his current term expires.

     SECTION  1.2    TERM.  Unless sooner terminated in accordance with the
provisions hereof, (a) the initial term of employment hereunder shall continue
until July 31, 1998; (b) on July 31 of each year, commencing with 1998, the term
of employment shall be extended for an additional period of one year unless,
prior to such July 31, either party shall have given notice to the other that
the term of employment shall not be so extended; and (c) if any such notice of
non-extension shall be so given, the term of employment shall end without any
further extensions except those occurring prior to the giving of such notice.

                             II.  COMPENSATION

     SECTION  2.1    BASE SALARY.  While Employee is employed hereunder, the
Company shall pay Employee a base salary of $800,000 per annum or such higher
amount or amounts as the Board of Directors of the Company may from time to time
approve.  The base salary shall be due and payable at the same times and
intervals at which salary payments are made to other senior executives.

     SECTION  2.2    INCENTIVE COMPENSATION.  Employee will be entitled to
participate in all incentive compensation and bonus



                                       -4-


plans maintained by the Company for its senior executives generally, including,
without limitation, the annual incentive compensation program, the Long-Term
Performance Incentive Plan, any Restricted Stock Award Program or their
successors.  During the term of his employment hereunder, the Employee's annual
incentive compensation will be at least 50% of his base salary for each year,
payable, with respect to each year, as promptly as practicable in the following
year.

     SECTION  2.3    EXECUTIVE SALARY PROTECTION PLAN.  The Company agrees that
the Employee will continue to be an "Eligible Executive" for purposes of its
Executive Salary Protection Plan.  The Company and the Employee have entered
into an agreement pursuant to SECTION 4(b) of the Executive Salary Protection
Plan, as now in effect, providing for the maximum benefits permitted by said
SECTION 4(b) on the basis that the "Recognized Compensation" of the Employee
will not be less than $20,833.34.  Notwithstanding any provision of such
agreement, the Company agrees that, while Employee is employed hereunder, the
benefits provided under such agreement at the time of its execution will not be
reduced.

     SECTION  2.4    STOCK OPTIONS.  Subject to the provisions of Article III,
Employee will be granted stock options covering at least 30,000 shares under the
Company's 1986 Stock Incentive Plan, or any successor Plan, in the month of
December in each year during the term of this Agreement, such options to vest



                                       -5-


and become exercisable as to 33 1/3% on each anniversary date of the date of
grant.

     SECTION  2.5    PENSIONS.

          (a)  Employee will continue to participate in the Company's Retirement
Plan for Salaried Employees ("Retirement Plan") and in the Company's
Supplemental Executive Retirement Plan ("SERP") in accordance with and subject
to their respective provisions.  In addition, Employee shall be paid a
supplementary pension ("Supplementary Pension") equal to such amounts as may be
payable under the Retirement Plan and SERP as a result of Employee's service
with the Company during the term of this Agreement and thereafter.  The
Supplementary Pension (payable by the Company from its general assets) shall be
a "mirror image" of his Retirement Plan and SERP pensions, and all rights,
obligations, elections and limitations of the Retirement Plan and SERP shall
apply to his Supplementary Pension except as otherwise provided in paragraphs
(b) and (c) below.  Employee may not, however, exercise his rights under the
Supplementary Pension independently of his rights under his Retirement Plan
pension; rights in respect of the Supplementary Pension may be exercised by, and
only by, the exercise of the corresponding rights under his Retirement Plan
pension.

          (b)  Notwithstanding any provisions of the Retirement Plan or SERP
with respect to vesting, the Company hereby guarantees that the aggregate annual
amount payable to Employee



                                       -6-


pursuant to paragraph (a) above, upon retirement, plus any other amounts payable
to Employee pursuant to any plan, provision or arrangement (including an
amendment to any existing plan) hereafter adopted or installed by the Company
for the purpose of replacing or supplementing, in whole or in part, the pension
benefits to be provided by the Retirement Plan or SERP (excluding any such
amount directly attributable to contributions by Employee), shall not be less
than the greater of (i) 50% of the Employee's average annual Pensionable
Compensation (as hereinafter defined) for the 60 consecutive calendar months in
which the Employee's Pensionable Compensation is highest during the final 180
calendar months of continuous employment ending prior to, or coincident with,
the date of the Employee's retirement, or (if earlier) other separation of
service, from the Company (the "Employee's Retirement Date") or (ii) 50% of the
Employee's Pensionable Compensation during the final 12 calendar month period
ending prior to, or coincident with, the Employee's Retirement Date, computed on
the basis of a straight life annuity commencing at age 62. "Pensionable
Compensation" means the sum of annual base salary and annual incentive
compensation payable to Employee from the Company that is regarded as includable
"compensation" under the Retirement Plan or SERP (whether or not any portion of
such salary or compensation is deferred under any Company plan or program).
Notwithstanding the foregoing, for purposes of this SECTION 2.5(b), if more than
five annual incentive compensation awards become payable



                                       -7-


to Employee during the 60 consecutive calendar month period referred to in
clause (i) of the first sentence of this SECTION 2.5(b), then only the largest
five such awards shall be considered annual incentive compensation during such
60 consecutive calendar month period; and if more than one annual incentive
compensation award becomes payable during the 12 calendar month period referred
to in clause (ii) of the first sentence of this SECTION 2.5(b), then only the
largest such award shall be considered annual incentive compensation during such
12 calendar month period.

          (c)  In the event the aggregate amount payable under paragraph (a) is
less than the amount guaranteed under paragraph (b), the Supplementary Pension
otherwise payable pursuant to paragraph (a) shall be increased by such
difference (after adjusting the increase actuarially to reflect the mode and
starting date of payment selected by Employee under the Retirement Plan as in
effect at that time of his retirement, if such mode and starting date is
different than a straight life annuity commencing at age 62).

     SECTION  2.6    EMPLOYEE BENEFITS.  Employee shall be entitled to
participate in and receive rights and benefits under any "fringe" benefit plans
which the Company provides for its executives generally, which at the present
time include:

          W. R. Grace & Co. Salaried Employees Savings & Investment Plan



                                       -8-


     -   The W. R. Grace & Co. Long Term Disability Income Plan

     -   The W. R. Grace & Co. Voluntary Group Accident Insurance Plan

     -   The W. R. Grace & Co. Business Travel Accident Insurance Plan

     -   The W. R. Grace & Co. Group Life, AD&D, Medical and Disability Plan

     -   The W. R. Grace & Co. Dental Assistance Plan

Employee's participation in such plans will be in accordance with and subject to
the terms and provisions thereof.

     SECTION  2.7    MISCELLANEOUS.

          (a)  Company will pay or reimburse Employee for his reasonable
business expenses in accordance with Company policies.

          (b)  Employee will be entitled to paid vacation aggregating not less
than four weeks during each twelve-month period. Employee will be entitled to
payment for unused vacation time in accordance with Company policy.

          (c)  The principal place of employment of Employee will be in Boca
Raton, Florida, or such other location as may be mutually agreed upon by the
Employee and the Company, subject to the travel requirements inherent in the
duties and responsibilities of his position.  The Employee will be provided with
office and secretarial services commensurate with his position.



                                       -9-


          (d)  Subject to SECTION 1.1(a) of this Agreement, compliance with
applicable laws relating to interlocking directorships, the Company's policies
on conflicts of interest and improper payments and accounting records contained
in a statement entitled "Policies on Business Ethics" and to any other
applicable Company policy, during the term of Employee's employment hereunder,
Employee will be permitted to accept election, and to serve as, a director of
other entities.  Employee will be permitted to retain all fees and other
benefits resulting from his service as a director of any such entity.

          (e)  The Company shall promptly pay upon demand any reasonable legal
fees incurred by Employee in connection with any enforcement of his rights under
this Agreement.

                             III.  TERMINATION

     SECTION 3.1     TERMINATION OF EMPLOYMENT.  The employment of Employee
shall terminate prior to the expiration of the term specified in SECTION 1.2
upon the occurrence of any of the following prior to such time:

     (a)  The death of Employee;

     (b)  The termination of Employee's employment due to Employee's disability
          pursuant to SECTION 3.2; or



                                      -10-


     (c)  The termination by the Company of Employee's employment
          for Cause pursuant to SECTION 3.3.

          The termination by the Company of Employee's employment hereunder for
any reason other than those specified in paragraphs (a), (b) and (c) above shall
hereinafter be referred to as a termination "Without Cause".

     SECTION 3.2     DISABILITY.  If, by reason of physical or mental
disability, Employee is unable to carry out the duties he has assumed pursuant
to this Agreement for four (4) consecutive months, his services hereunder may be
terminated by the Company upon two (2) months' written notice to be given to
Employee at any time after the period of four (4) continuous months of
disability and while such disability continues.  If, prior to the expiration of
the two (2) months after the giving of such notice, Employee shall recover from
such disability and return to the active discharge of his duties, then such
notice shall be of no further force and effect and Employee's employment shall
continue as if the same had been uninterrupted.  If Employee shall not so
recover from his disability and return to his duties, then his services shall
terminate at the expiration date of such two (2) months' notice.  During the
period of Employee's disability and until the expiration date of such two (2)
months' notice, Employee shall continue to receive all compensation and other
benefits provided herein as if he had not been disabled, at the time, in the
amounts and in the



                                      -11-


manner provided herein.  In the event a dispute arises between Employee and the
Company concerning Employee's physical or mental ability to continue or return
to the performance of his duties as aforesaid, Employee shall submit to
examination by a competent physician mutually agreeable to both parties, and
such physician's opinion as to Employee's ability to so perform will be final
and binding.

          Upon termination of Employee's employment hereunder due to Employee's
disability, Employee shall receive annual compensation in an amount equal to the
amount which would have been payable to Employee pursuant to SECTION 2.5 hereof
based on his years of service at the date of such termination but unreduced for
early commencement of such payments.  If the termination of Employee's
employment hereunder due to Employee's disability occurs prior to age 62,
Employee may elect at any time after age 55 and prior to age 62 to receive in
lieu of the payments pursuant to the preceding sentence of this SECTION 3.2 the
amount payable under SECTION 2.5 hereof computed by giving credit for years of
service for the period during which Employee received payments hereunder (but
not beyond age 62) but reduced for early commencement as provided in the
Retirement Plan and SERP.

          Any amounts paid to Employee under this SECTION 3.2 shall be reduced
by amounts paid to him under SECTION 2.5 hereof.

     SECTION 3.3     FOR CAUSE.  The Company may, at any time by written notice
to the Employee, terminate his services here-



                                      -12-


under for Cause.  Such notice shall specify the event or events and the actions
or failure to act constituting Cause.  The term "Cause", as used herein, shall
mean and be limited to the occurrence of one or more of the following events:

     (a)  His conviction, by a court of competent jurisdiction,
          of a felony, which through lapse of time or otherwise
          is not subject to appeal;

     (b)  His commission of an act of fraud upon, or an act evidencing material
          dishonesty toward, the Company; or

     (c)  Any willful failure by him to observe or perform his
          material agreements herein contained.

          If the basis for discharge is pursuant to paragraph (c) above,
Employee shall have thirty (30) days from his receipt of the notice of
termination for Cause to cure the actions or failure to act specified in such
notice and, in the event of any such cure within such period, such conduct shall
not constitute Cause hereunder.

     SECTION 3.4     CONSEQUENCES OF TERMINATION.

          (a)  If Employee's employment hereunder shall terminate pursuant to
any of the provisions of this Article III, (i) his base salary and incentive
compensation referred to in SECTIONSECTION 2.1 and 2.2 shall cease to accrue
forthwith; and (ii) no



                                      -13-


stock options shall thereafter be granted to Employee pursuant to SECTION 2.4.

          (b)  If the Company shall terminate Employee's employment hereunder
Without Cause, the Company shall pay Employee monthly severance payments at an
annual rate equal to 150% of the Employee's base salary in effect at the time of
such termination. Such monthly severance payments shall be made for a period
equal to the balance of the term of employment provided for in SECTION 1.2
(without any further extensions of such term of employment except those
occurring prior to such termination); provided, however, that the severance
payments shall be reduced by one-half the amount of any Earned Income (as
hereinafter defined) received by the Employee from other sources for any period
such severance payments are payable, and, provided further, that such severance
payments shall not thereby be reduced to less than a rate of $60,000 per annum.
For the purposes of the foregoing, "Earned Income" shall mean income
attributable to the rendition of personal services including salary, bonuses and
incentive or other supplementary compensation, whether payable currently or
deferred, and whether payable in cash or in property.  Benefits attributable to
executive or employee stock options, benefit plans or other arrangements of the
type referred to in SECTION 2.3 through SECTION 2.7 shall not constitute Earned
Income.  Incidental honorariums or consulting fees received on an infrequent
basis while working full-time for another employer shall not be included in
Earned



                                      -14-


Income.  However, consulting fees, finders' fees and other income for personal
services (other than directors' fees) received in lieu of employment by others,
or received on a regular and continuing basis even if employed by another
employer, shall be included in Earned Income.  Directors' fees shall not be
included in Earned Income.

          (c)  In the event that Employee's employment hereunder shall terminate
pursuant to any of the provisions of this Article III, the rights of Employee
under any incentive compensation plan referred to in SECTION 2.2, under the
executive or employee benefit plans or arrangements referred to in
SECTIONSECTION 2.3, 2.5 and 2.6, and under any stock options to Employee granted
pursuant to SECTION 2.4, or otherwise, shall be determined in accordance with
the terms and provisions of such plans, arrangements and options applicable to
an employee whose employment has terminated in the manner that occurred, except
that a termination Without Cause shall be treated as a retirement under a
retirement plan of the Company for the purposes of SECTION 6(c) of the Company's
1986 Stock Incentive Plan or any comparable provision of any successor plan or
other stock option plan of the Company.



                                      -15-


                     IV.  OTHER COVENANTS OF EMPLOYEE

     SECTION 4.1     Employee shall have no right, title or interest in any
reports, studies, memoranda, correspondence, manuals, records, plans, or other
written, printed or otherwise recorded materials of any kind belonging to or in
the possession of the Company or its subsidiaries, or in any copies, pictures,
duplicates, facsimiles or other reproductions, recordings, abstracts or
summaries thereof and Employee will promptly surrender to the Company any such
materials (other than materials which have been published or otherwise have
lawfully been made available to the public generally) in his possession upon the
termination of his employment or any time prior thereto upon request of the
Company.

     SECTION 4.2     Without the prior written consent of the Company, Employee
shall not at any time (whether during or after his employment with the Company)
use for his own benefit or purposes or for the benefit or purposes of any other
person, firm, partnership, association, corporation or business organization,
entity or enterprise, or disclose (except in the performance of his duties
hereunder) in any manner to any person, firm, partnership, association,
corporation or business organization, entity or enterprise, any trade secret, or
other confidential or proprietary information, data, know-how or knowledge
(including, but not limited to, that relating to manufacturing organization and
methods, research and development of products,



                                      -16-


service techniques, purchasing organization and methods, sales organization and
methods, inventories, market development and expansion plans, personnel training
and development programs, customer and supplier relationships, and franchising
plans and franchisee relationships) belonging to, or relating to the affairs of,
the Company or its subsidiaries.

     SECTION 4.3     Employee shall promptly disclose to the Company (and to no
one else) all improvements, discoveries and inventions that may be of
significance to the Company or its subsidiaries made or conceived alone or in
conjunction with others (whether or not patentable, whether or not made or
conceived at the request of or upon the suggestion of the Company during or out
of his usual hours of work or in or about the premises of the Company or
elsewhere) while in the employ of the Company, or made or conceived within six
months after the termination of his employment by the Company, if resulting
from, suggested by or relating to such employment.  All such improvements,
discoveries and inventions shall, to the extent that they are patentable, be the
sole and exclusive property of the Company and are hereby assigned to the
Company.  At the request of the Company and at its cost and without liability to
Employee, Employee shall assist the Company, or any person or persons from time
to time designated by it, in obtaining the grant of patents in the United States
and/or in such other country or countries as may be designated by the Company
covering such improvements, discoveries and inventions and shall in connection
therewith



                                      -17-


execute such applications, statements or other documents, furnish such
information and data and take all such other action (including, but not limited
to, the giving of testimony) as the Company may from time to time request.

     SECTION 4.4     The obligations of Employee set forth in this Article IV
are in addition to and not in limitation of any obligations which would
otherwise exist as a matter of law.  The provisions of this Article IV shall
survive the termination of Employee's employment hereunder.


                           V.  CERTAIN REMEDIES

     SECTION 5.1     BREACH BY THE COMPANY.  In the event that the Company shall
fail, in any material respect, to observe and perform its obligations hereunder,
the Employee may give written notice to the Company specifying the nature of
such failure.  If within thirty (30) days after its receipt of such notice the
Company shall not have remedied such failure, the Employee shall have the right
and option to treat such failure as termination of his employment by the Company
Without Cause, to cease rendering services hereunder and thereafter to receive
the severance benefits and have the other rights and obligations provided for in
Article III hereof in the case of a termination by the Company Without Cause.
The parties agree that a material breach by the Company for purposes of this
SECTION 5.1 shall include, but not be limited to, a material reduction in
Employee's authority or responsibilities from those he



                                      -18-


was exercising on the date of execution of this Agreement.  The remedy provided
for in this SECTION 5.1 shall be in addition to and not in limitation of any
other remedies which would otherwise exist as a matter of law.

     SECTION 5.2     BREACH BY THE EMPLOYEE.  Employee acknowledges and agrees
that the Company's remedy at law for any breach of any of Employee's obligations
under SECTIONS 1.1(a), 4.1, 4.2 and 4.3 would be inadequate, and agrees and
consents that temporary and permanent injunctive relief may be granted in
any proceeding that may be brought to enforce any provision of any such
sections, without the necessity of proof of actual damage.

                          VI.  GENERAL PROVISIONS

     SECTION 6.1     REPRESENTATIONS AND WARRANTIES.  Employee represents and
warrants to the Company that he is free to enter into the agreement and that he
has no prior or other obligations or commitments of any kind to anyone that
would in any way hinder or interfere with his acceptance of, or the full,
uninhibited and faithful performance of, his employment hereunder or the
exercise of his best efforts as an employee of the Company.

     SECTION 6.2     UNDERSTANDINGS; AMENDMENTS.  Except as otherwise provided
herein, or as set forth in Annex A hereto, this Agreement sets forth the entire
agreement and understanding of the parties concerning the subject matter hereof

                                      -19-


Employee and the Company concerning such subject matter.  No representation,
promise, inducement or statement of intention has been made by or on behalf of
