         This Amendment is being filed to provide the information called for by
Items 11 and 13 of the Annual Report on Form 10-K of W. R. Grace & Co. ("New
Grace"), a Delaware corporation formerly named "Grace Specialty Chemicals,
Inc.," for the year ended December 31, 1997. As used in this Amendment, the
term "Grace" refers to W. R. Grace & Co., a Delaware corporation renamed
"Sealed Air Corporation" that was formerly the sole shareholder of New Grace.
In March 1998, Grace's flexible packaging business was separated from New
Grace, and Grace effected the spin-off of New Grace; these transactions are
referred to in this Amendment as the "1998 Transactions." Additional
information regarding the 1998 Transactions is contained in (a) the Joint Proxy
Statement/Prospectus of Grace dated February 13, 1998, included in a
Registration Statement on Form S-4 (File No. 333-46281) filed by Grace on
February 13, 1998 under the Securities Act of 1933, as amended, and (b) the
Information Statement of New Grace dated February 13, 1998, included in a
Registration Statement on Form 10 (File No. 001-13953) filed by New Grace on
March 13, 1998 under the Securities Exchange Act of 1934, as amended 
("Form 10").

(a)      Other than the award to Mr. Ellberger, no restricted stock awards were
         made during the 1995-1997 period. The dollar value of Mr. Ellberger's
         1,500 restricted shares shown in the table has not been adjusted to
         give effect to (i) the September 1996 separation of Grace's principal
         health care business or (ii) the 1998 Transactions. At December 31,
         1997, the dollar value of these restricted shares was $120,656,
         excluding the value of additional securities received by Mr. Ellberger
         in respect of these restricted shares in the September 1996
         transaction and the 1998 Transactions. The restrictions on these
         shares are to terminate on May 14, 1998 (see "Employment Agreements")
         or earlier, in the event of Mr. Ellberger's death or disability or the
         termination of his employment without cause (including following a
         change of control), subject to the forfeiture of the shares in certain
         circumstances. Mr. Ellberger receives all dividends paid on, and has
         the right to vote, these restricted shares.

(b)      The share amounts shown in this column reflect adjustments made in
         September 1996 in connection with the separation of Grace's principal
         health care business. They do not reflect any adjustments for the 1998
         Transactions (see "Stock Options").

(c)      The amounts in this column for 1997 represent awards earned under the
         Long-Term Incentive Program ("LTIP") for the 1994-1996 Performance
         Period. The amounts in this column for 1996 represent awards earned
         under the LTIP for the 1993-1995 Performance Period. The amounts in
         this column for 1995 represent the third and final installments of
         awards earned under the LTIP for the 1990-1992 Performance Period.

(d)      The amounts in this column for 1997 consist of the following: (i) the
         actuarially determined value of company-paid premiums on
         "split-dollar" life insurance, as follows: Mr. Beber -- $17,179; Mr.
         Bettacchi -- $5,273; Mr. Hyde -- $6,984; and Mr. Kaenzig -- $4,523;
         (ii) life insurance premiums of $10,170 for Mr. Costello and $1,204
         for Mr. Ellberger, who do not participate in the split-dollar life
         insurance program; (iii) payments made to persons whose personal
         and/or company contributions to Grace's Salaried Employees Savings and
         Investment Plan ("Savings Plan") would be subject to limitations under
         federal income tax law, as follows: Mr. Costello -- $41,412; Mr.
         Ellberger -- $8,763; Mr. Beber -- $9,150; Mr. Bettacchi -- $7,187; Mr.
         Hyde -- $7,568; and Mr. Kaenzig -- $7,160; and (iv) company
         contributions to the Savings Plan of $4,800 for each of Messrs.
         Costello, Ellberger, Beber, Bettacchi, Hyde and Kaenzig.

(e)      Messrs. Costello and Ellberger joined Grace's predecessor in May 1995.

         Stock Options. The following table contains information concerning
stock options granted in 1997, including the potential realizable value of each
grant assuming that the market value of the Grace common stock were to
appreciate from the date of grant to the expiration of the option at annualized
rates of (a) 5% and (b) 10%, in each case compounded annually over the term of
the option. The assumed rates of appreciation shown in the table have been
specified by the SEC for illustrative purposes only and are not intended to
predict future stock prices, which will depend upon various factors, including
market conditions and future performance and prospects.

         Options become exercisable at the time or times determined by the
Compensation Committee of the Board of Directors; the options shown below
become exercisable in three approximately equal annual installments beginning
one year after the date of grant or upon the earlier occurrence of a "change in
control" (see "Employment Agreements" and "Severance Agreements"). All of the
options shown below have purchase prices equal to the fair market value of
Grace's common stock at the date of grant.

         In connection with the 1998 Transactions, all outstanding options
(other than those held by employees of Grace's flexible packaging business,
including Mr. Kaenzig) became options to


                                      -3-




purchase New Grace common stock, and the number of shares covered by and
purchase prices of such options were adjusted to preserve their economic value;
the options held by employees of the flexible packaging business (including Mr.
Kaenzig) became options to purchase common stock of Grace (renamed "Sealed Air
Corporation") and were similarly adjusted. The following table does not reflect
such adjustments.




                                                                                                 POTENTIAL REALIZABLE VALUE AT

         The following table contains information concerning stock options
exercised in 1997, including the "value realized" upon exercise (the difference
between the total purchase price of the options exercised and the market value,
at the date of exercise, of the shares acquired), and the value of unexercised
"in-the-money" options held at December 31, 1997 (the difference between the
aggregate purchase price of all such options held and the market value of the
shares covered by such options at December 31, 1997). The amounts in this table

         LTIP. Under the LTIP as in effect during 1997, executive officers and
other senior managers were granted contingent "Performance Units" under which
awards could be earned

                                      -4-



based on shareholder value performance (measured by appreciation in the price
of Grace common stock and dividends paid), as compared to that of the companies
in the Standard & Poor's Industrials Index, during a three-year "Performance
Period." The number of Performance Units earned under the LTIP could be
decreased by up to 20%, at the discretion of the Compensation Committee, based
upon individual performance. Amounts, if any, earned under the Performance
Units granted in 1997 were to be paid as promptly as practicable following
year-end 1999 (i.e., the end of the 1997-1999 Performance Period), with up to
100% of any such payments being made in shares of Grace common stock, as
determined by the Compensation Committee. Cash payments under earned
Performance Units may be deferred, earning interest equivalents computed at the
prime rate, compounded semiannually; payments made in common stock may be
deferred by means of a deferred compensation trust established by Grace (and
continued by New Grace). Deferred amounts are generally payable to the
participant following termination of employment.

         In connection with the 1998 Transactions, the Compensation Committee
determined, in accordance with the LTIP, that (a) Performance Units granted for
the 1996-1998 and 1997-1999 Performance Periods should vest on a pro rata basis
upon completion of the 1998 Transactions; (b) the amounts earned under those
Units should be calculated based on results achieved through the date of
completion of the 1998 Transactions; (c) 75% of the estimated value of such
vested portions should be paid in cash prior to completion of the 1998
Transactions; (d) the balance of such vested portions should be paid in cash
following completion of the 1998 Transactions; and (e) the value of the
unvested portions, which would be based on targeted Performance Units and on
the final average price of Grace common stock immediately prior to completion
of the 1998 Transactions, should be paid in cash following the end of the
respective Performance Periods (subject to continued service). The Compensation
Committee has also determined that no further grants will be made under the
LTIP.

         The following table shows the Performance Units granted during 1997 to
the executive officers named in the Summary Compensation Table. All of such
Performance Units relate to the 1997-1999 Performance Period.

(a)      Refers to the minimum amount payable under the LTIP with respect to
         the 1997-1999 Performance Period. Under the initial terms of the
         grants, no payment would be made unless the minimum targeted level of
         shareholder value performance was achieved. (However, see above for
         information regarding the treatment of Performance Units for the
         1997-1999 Performance Period in the 1998 Transactions.)

(b)      The threshold and target payments shown in the table were calculated
         on the basis of an assumed market price of $75 per share of Grace
         common stock at the end of the 1997-1999 Performance Period. (However,
         see above for information regarding the treatment of Performance Units
         for the 1997-1999 Performance Period in the 1998 Transactions.)

(c)      Refers to the amount payable under the initial terms of the grants
         with respect to the 1997-1999 Performance Period if the targeted level
         of shareholder value performance were achieved. (However, see above
         for information regarding the treatment of Performance Units for the
         1997-1999 Performance Period in the 1998 Transactions.)

         Pension Arrangements. Salaried employees of designated units who are
21 or older and who have one or more years of service are eligible to
participate in the Retirement Plan for Salaried Employees. Under this basic
retirement plan, pension benefits are based upon (a) the employee's average
annual compensation for the 60 consecutive months in which his or her
compensation is highest during the last 180 months of continuous participation
and (b) the number of years of the employee's credited service. For purposes of
this basic retirement plan, compensation generally includes nondeferred base
salary and nondeferred annual incentive compensation (bonus) awards; however,
for 1997, federal income tax law limited to $160,000 the annual compensation on
which benefits under this plan may be based.

         Grace also had (and New Grace has) a Supplemental Executive Retirement
Plan under which a covered employee will receive the full pension to which he
or she would be entitled in the absence of the above and other limitations
imposed under federal income tax law. In addition, this supplemental plan
recognizes deferred base salary, deferred annual incentive compensation awards
and, in some cases, periods of employment during which an employee was
ineligible to participate in the basic retirement plan. An employee will
generally be eligible to participate in the supplemental plan if he or she has
an annual base salary of at least $75,000 and is earning credited service under
the basic retirement plan.

         The following table shows the annual pensions payable under the basic
and supplemental plans for different levels of compensation and years of
credited service. The amounts shown have been computed on the assumption that
the employee retired at age 65 on January 1, 1998, with benefits payable on a
straight life annuity basis. Such amounts are subject to (but do not reflect)
an offset of 1.25% of the employee's primary Social Security benefit at
retirement age for each year of credited service under the basic and
supplemental plans.

         At December 31, 1997, Messrs. Costello, Ellberger, Beber, Bettacchi,
Hyde and Kaenzig had 3, 3, 10, 26, 35 and 26 years of credited service,
respectively, under the basic and supplemental retirement plans. For purposes
of those plans, the 1997 compensation of such executive officers was as
follows: Mr. Costello -- $1,540,408; Mr. Ellberger -- $452,083; Mr. Beber --
$465,000; Mr. Bettacchi - $399,350; Mr. Hyde -- $412,600; and Mr. Kaenzig --
$398,666. Mr. Ellberger is entitled to certain pension benefits under his
employment agreement (see "Employment Agreements").

         Employment Agreements. Mr. Costello has an employment agreement (which
has been assumed by New Grace) providing for his service as chairman, president
and chief executive officer through April 1999, subject to (a) earlier
termination in certain circumstances and (b) automatic one-year extensions
unless either party gives notice that the agreement is not to be extended. The
agreement also provides that Mr. Costello will stand for election as a director
during its term. Under the agreement, Mr. Costello is entitled to an annual
base salary of at least $900,000; an annual incentive compensation award
(bonus) of at least $900,000 for 1995 and awards thereafter based on
performance, in accordance with the annual incentive compensation program;
participation in the LTIP on the same basis as other senior executives; grants
of stock

                                      -7-





options; and participation in all other compensation and benefit plans and
programs generally available to senior executives. The agreement also provides
for payments in the case of Mr. Costello's disability or death or the
termination of his employment with or without cause, including termination
following a "change in control" and termination by Mr. Costello for "good
reason." For purposes of the agreement, "change in control" means the
acquisition of 20% or more of the New Grace common stock, the failure of
Board-nominated directors to constitute a majority of any class of the Board of
Directors, the occurrence of a transaction in which the shareholders of New
Grace immediately preceding such transaction do not own more than 60% of the
combined voting power of the corporation resulting from such transaction, or
the liquidation or dissolution of New Grace. In the event of the termination of
Mr. Costello's employment following a change in control, he will receive a
multiple of the sum of his annual base salary plus bonus, pro rata bonus and
LTIP awards, earned but unpaid compensation, and the balance of the LTIP awards
for all Performance Periods during which the change in control takes place. The
foregoing description of Mr. Costello's employment agreement does not purport
to be complete and is qualified in its entirety by reference to such agreement,
which was filed with the SEC as an exhibit to the Quarterly Report on Form 10-Q
of Grace's predecessor for the quarter ended June 30, 1995, and by reference to
an amendment to such agreement, which was filed with the SEC as an exhibit to
Grace's Current Report on Form 8-K filed on October 10, 1996.

         Mr. Ellberger has an employment agreement (which has been assumed by
New Grace) providing for his service as senior vice president, strategic
planning and development, through May 14, 1998; at that time, the agreement
will terminate (except with respect to the retirement arrangements described
below) and his employment will be "at will." The agreement provides for an
initial annual base salary of $275,000; participation in the annual incentive
compensation program, LTIP, and other compensation and benefit plans and
programs; the grant of stock options; and the grant of the restricted stock
award shown in the Summary Compensation Table. The agreement also provides that
if Mr. Ellberger's employment is terminated without cause during the term of
the agreement (except in the event of a change in control), he will receive
145% of his base salary for one year or, if longer, the remaining term of the
agreement. In addition, the agreement provides that, in determining the
benefits payable to Mr. Ellberger under the basic and supplemental retirement
plans, his service with his prior employer will be recognized as if it were
continuous service with Grace and/or New Grace, with an offset for any
retirement benefits payable from his prior employer's retirement plans;
however, this special pension arrangement will apply only if Mr. Ellberger's
employment ceases after the term of the agreement (or during such term, if his
employment is terminated without cause, including termination without cause
following a change in control). The agreement also provides for standard
relocation assistance arrangements and for a leased car. For purposes of the
agreement, "change in control" has the same meaning as in Mr. Costello's
agreement, described above. The foregoing description of Mr. Ellberger's
employment agreement does not purport to be complete and is qualified in its
entirety by reference to such agreement and related agreements, which were
filed as exhibits to Grace's Annual Report on Form 10-K for the year ended
December 31, 1996.


                                      -8-





         Severance Agreements. New Grace has severance agreements with all of
its executive and other officers (except for Mr. Costello, whose employment
agreement, discussed above, provides for severance arrangements). These
agreements generally provide that in the event of the involuntary termination
of the individual's employment without cause (including constructive
termination caused by a material reduction in his or her authority or
responsibility) following a change in control of New Grace, he or she will
receive a severance payment equal to three times the sum of his or her annual
base salary plus target annual incentive compensation (bonus), subject to pro
rata reduction in the case of an officer who is within 36 months of normal
retirement age (65). For purposes of the severance agreements, the definition
of "change in control" is identical to the definition contained in Mr.
Costello's employment agreement (see "Employment Agreements"), except that,
under the severance agreements, a "change in control" (a) does not include the
acquisition of 20% or more of New Grace's common stock as a result of a sale of
stock by New Grace and (b) includes a transaction in which the shareholders of
New Grace do not own 50% or more of the voting power of the corporation
resulting from such transaction (as compared to more than 60% under Mr.
Costello's agreement). This description of the severance agreements does not
purport to be complete and is qualified in its entirety by reference to the
form of such agreement, which was filed as an exhibit to the Form 10.

         Executive Salary Protection Plan. All executive and other officers
participate in the Executive Salary Protection Plan ("ESPP"), which provides
that, in the event of a participant's disability or death prior to age 70, New
Grace will continue to pay all or a portion of base salary to the participant
or a beneficiary for a period based on the participant's age at the time of
disability or death. Payments under the ESPP may not exceed 100% of base salary
for the first year and 60% thereafter in the case of disability (50% in the
case of death). This description of the ESPP does not purport to be complete
and is qualified in its entirety by reference to the text of the ESPP, as
amended, which was filed as an exhibit to Grace's Annual Report on Form 10-K
for the year ended December 31, 1996.

         Directors' Compensation and Consulting Arrangements. Under the
compensation program for nonemployee directors, (a) each nonemployee director
receives an annual retainer of $50,000, of which $35,000 is in the form of New
Grace common stock and the balance is in cash or New Grace common stock, at the
election of the director; (b) each committee chair receives an additional
annual retainer of $3,000 in cash or New Grace common stock, at the election of
the director; and (c) each nonemployee director receives $2,000 for each Board
meeting and $1,000 for each committee meeting attended (except that committee
chairs receive $1,200 per committee meeting), in cash or New Grace common
stock, at the election of the director.

         A nonemployee director may defer payment of all or part of the fees
received for attending Board and committee meetings and/or the cash retainers
(or cash portions of the retainers) referred to above. The deferred cash (plus
an interest equivalent) is payable to the director or his or her heirs or
beneficiaries in a lump sum or in quarterly installments over two to 20 years 

                                      -9-



following a date specified by the director (but in no event earlier than the
director's termination from service). The interest equivalent on deferred cash
is computed at the higher of (a) the prime rate plus two percentage points or
(b) 120% of the prime rate, in either case compounded semiannually. The portion
of the annual retainer payable in New Grace common stock may be deferred and
held, and the balance of the annual retainer or other retainers and/or fees a
director elects to receive in the form of New Grace common stock will be
deferred and held, in a deferred compensation trust established by Grace (and
continued by New Grace). New Grace common stock held in the trust will be
delivered to the director following his or her termination from service (or a
subsequent date specified by the director).

         Nonemployee directors are reimbursed for expenses they incur in
attending Board and committee meetings; Grace also maintained (and New Grace
continues to maintain) business travel accident insurance coverage for them. In
addition, nonemployee directors may receive $1,000 per day for work performed
at the request of New Grace.

         Virginia A. Kamsky served as a nonemployee director of Grace during
1997. Grace previously had a consulting agreement with Kamsky Associates Inc.
(of which Ms. Kamsky is chairman and co-chief executive officer) relating to
its interests in The People's Republic of China. The agreement expired on May
31, 1997 (and was not renewed) and provided for monthly fees of $25,000, plus
additional payments based on the extent to which Grace established certain
business relationships in The People's Republic of China. In 1997, Grace paid
fees totaling $125,000 under this agreement. The foregoing description does not
purport to be complete and is qualified in its entirety by reference to the
agreement referred to above, which was filed with the SEC as an exhibit to the
Annual Report on Form 10-K of Grace's predecessor for the year ended December
31, 1992.

         Compensation Committee Interlocks and Insider Participation. Harold A.
Eckmann, Thomas A. Holmes, John E. Phipps and Thomas A. Vanderslice served as
members of the Compensation Committee throughout 1997. John F. Akers joined the
Compensation Committee in January 1997 and John J. Murphy in March 1997. Mr.
Holmes served as acting president and chief executive officer of Grace's
predecessor for a two-month period in 1995.


ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.
         ------------------------------------------------

         The following are descriptions of certain relationships and
transactions between Grace and its directors and executive officers and/or
businesses with which they are affiliated. Information regarding certain
consulting arrangements appears under "Directors' Compensation and Consulting
Arrangements" in Item 11 above.

         Commercial Transactions. Mr. Costello is a director of Becton,

1997, various Grace business units sold approximately $270,000 of materials
and/or products to units of Becton Dickinson. In

                                      -10-




addition, during 1997 various Grace business units purchased approximately $1.3
million of materials and/or products from, and sold approximately $125,000 of
materials and/or products to, FMC. These transactions were in the ordinary
course of business and were on terms believed to be similar to those with
unaffiliated parties.

         Legal Proceedings; Indemnification. Information concerning legal
proceedings in which current and/or former executive officers and/or directors
of Grace or its predecessor are parties or are otherwise involved appears under
the headings "Stockholder Litigation," "Securities and Exchange Commission
Investigation," and "Claims Relating to NMC" in Item 3 ("Legal Proceedings") of
Grace's Annual Report on Form 10-K for the year ended December 31, 1997.
