(1)  This table does  not reflect  the sale, subsequent  to March  31, 1994,  of
     $108.5  million principal amount of Medium-Term Notes or the application of
     the $108.1  million of  net proceeds  therefrom to  repay commercial  paper
     borrowings  and/or bank borrowings. The Medium-Term Notes mature at various
     dates from 1996 to 1999 and bear interest at rates from 6.55% to 7.84%  per
     annum or at floating rates based on LIBOR.

(2)  Under  its bank revolving  credit agreement, Grace may  borrow up to $1,225
     million at interest rates  based upon the  prevailing prime, federal  funds
     and/or  Eurodollar rates. Of the $1,225 million, approximately $715 million
     is available under  a 364-day facility  expiring August 29,  1994, and  the
     remainder  is available under  a three-year facility  expiring September 1,
     1995. At March 31, 1994, borrowings  of $63 million were outstanding  under
     the  revolving credit agreement; these borrowings are included in Long-Term
     Debt - Commercial paper and bank borrowings above. At March 31, 1994,  $779
     million  was reserved to support commercial paper borrowings and other bank
     borrowings outstanding,  leaving  net  unused  credit  facilities  of  $383
     million.  Grace's  ability to  borrow the  maximum amounts  available under
     these facilities is subject to compliance with certain covenants, including
     minimum net worth and interest coverage requirements. Grace believes  that,
     as  of March 31, 1994, after giving effect to the sale of the Notes offered
     hereby, the financings  referred to  in Note  (1) above  and the  after-tax
     charge  referred to in the  above table, it would  have been able to borrow
     from approximately $409 million to  $789 million of additional funds  under
     the  revolving  credit agreement,  depending  upon the  application  of the
     proceeds of such borrowings.

    of the Indenture).

                                       4

        (12)  If other than the entire principal amount thereof, the portion  of

    so, whether  beneficial  owners of  interests  in any  Global  Security  may
    exchange  such interests for Debt Securities of like tenor of any authorized
    form and denomination and the  circumstances under which any such  exchanges

    of the depository for such Debt Securities.

        (19)  The person to whom any interest on any Registered Security will be

    or more Predecessor Securities)  is registered at the  close of business  on

        (20)   The denomination  or denominations in  which such Debt Securities

    inconsistent with the provisions of the Indenture (Section 301).

    If applicable, the  Prospectus Supplement  will also  set forth  information
concerning any Warrants offered thereby and a discussion of any relevant federal
income tax considerations.

                                       5
<PAGE>
    Debt  Securities  may  provide for  less  than the  entire  principal amount
thereof to be due and payable upon a declaration of acceleration of maturity.  A
discussion  of the federal income tax and other considerations applicable to any
Original  Issue  Discount  Securities  will  be  set  forth  in  the  Prospectus
Supplement relating thereto.

    If  the terms of any  series of Debt Securities  provide that the Company or
the Guarantor may be required to pay Additional Amounts in respect thereof,  for
purposes  of this Prospectus, any  reference to the payment  of the principal of
(and premium, if any, on) or interest,  if any, on such Debt Securities will  be
deemed  to include mention of the payment of the Additional Amounts provided for
by the terms of such Debt Securities.

    The Debt Securities will  be unsecured obligations of  the Company and  will
rank  on a parity  with all other unsecured  and unsubordinated indebtedness for
borrowed money of  the Company. The  Debt Securities will  be guaranteed by  the
Guarantor as provided below.

    The  Debt Securities referred to  on the cover page  of this Prospectus, and
any  additional  debt  securities  issued   under  the  Indenture,  are   herein
collectively  referred to, while a single Trustee  is acting with respect to all
debt securities issued thereunder, as the "Indenture Securities". The  Indenture
provides  that there may be more than  one Trustee thereunder, each with respect
to one  or more  series of  Indenture Securities.  At a  time when  two or  more
Trustees  are  acting under  the Indenture,  each with  respect to  only certain
series, the term "Indenture Securities" as used herein will mean the series with
respect to which each respective Trustee is  acting. In the event that there  is
more  than one Trustee under the Indenture,  the powers and trust obligations of
each Trustee as  described herein will  extend only to  the series of  Indenture
Securities for which it is the Trustee. If two or more Trustees are acting under
the  Indenture, then the  Indenture Securities for which  each Trustee is acting
would be treated as if issued under separate indentures.

    The general provisions  of the  Indenture do not  limit the  ability of  the
Company or the Guarantor to incur indebtedness and do not afford holders of Debt
Securities  protection in the event of  highly leveraged or similar transactions
involving the Company or the Guarantor.  However, the general provisions of  the
Indenture  do provide that neither the Company, the Guarantor nor any Restricted
Subsidiary will subject certain of its  properties or assets to any mortgage  or
other  encumbrance unless  the Indenture Securities  outstanding thereunder, the
related Guarantees or both, as the case may be, are secured equally and  ratably
with  or prior to such other indebtedness thereby secured. See "Liens" and "Sale
and Leaseback Transactions" under the heading "Certain Covenants". Reference  is
made  to the Prospectus Supplement for information with respect to any deletions
from, modifications of or additions to the Events of Default or covenants of the
Company and the Guarantor that are described below, including any addition of  a
covenant or other provision providing event risk or similar protection.

    If  any series of Debt Securities is  sold for, payable in or denominated in
one or  more  Currencies  other  than  U.S.  dollars,  applicable  restrictions,
elections,  terms and  other information  with respect  to such  series and such
Currencies, and a discussion of the federal income tax and other  considerations
applicable  thereto, will  be set  forth in  the Prospectus  Supplement relating
thereto.

    Under the  Indenture,  the  Company  has  the  ability  to  issue  Indenture
Securities  with terms different  from those of  Indenture Securities previously
issued thereunder and, without the consent of the holders, to reopen a  previous
issue  of  a  series  of Indenture  Securities  and  issue  additional Indenture
Securities of such series (unless such reopening was restricted when such series
was created) in an aggregate principal amount determined by the Company (Section
301).

    There is no requirement that future issues of debt securities of the Company
be issued under  the Indenture, and  the Company  will be free  to employ  other
indentures or documentation, possibly containing provisions different from those
included  in the  Indenture or  applicable to  one or  more issues  of Indenture
Securities, in connection with such future issues.

                                       6

GUARANTEES

    The Debt  Securities will  have  endorsed thereon  Guarantees by  which  the
Guarantor  will unconditionally  guarantee the due  and punctual  payment of the
principal of  (and premium,  if  any, on)  and interest,  if  any, on  the  Debt
Securities,  when and  as the  same become  due and  payable, whether  at Stated
Maturity, upon  redemption or  repayment, upon  declaration of  acceleration  or
otherwise.

    The  Guarantees will be unsecured obligations of the Guarantor and will rank
on a  parity  with  all  other unsecured  and  unsubordinated  indebtedness  for
borrowed   money   of  the   Guarantor  (including   any  other   unsecured  and
unsubordinated guarantees given by the Guarantor).

    The  Guarantees  will  be   unconditional  obligations  of  the   Guarantor,
regardless of the enforceability of the related Debt Securities or the Indenture
(Section 1701).

FORM AND DENOMINATIONS

    Debt Securities of a series may be issuable solely as Registered Securities,
solely  as  Bearer  Securities  or  as  both  Registered  Securities  and Bearer
Securities. Unless otherwise provided  in the applicable Prospectus  Supplement,
Debt Securities denominated in U.S. dollars (other than Global Securities, which
may be of any denomination) are issuable in denominations of $1,000 and integral
multiples  of  $1,000  (in  the  case  of  Registered  Securities)  and  in  the
denomination of $5,000 (in  the case of Bearer  Securities). The Indenture  also
provides  that Debt Securities of  a series may be  issuable in global form. See
"Book-Entry Debt Securities" below. Unless otherwise indicated in the applicable
Prospectus Supplement,  Bearer Securities  will have  interest coupons  attached
(Sections 201 and 302).

PAYMENT, TRANSFER AND EXCHANGE

    If Debt Securities of a series are issuable solely as Registered Securities,
the  Company and the Guarantor will be  required to maintain an office or agency
in each Place of Payment  for such series, and may  from time to time  designate
additional  offices or agencies, at which the principal of (and premium, if any,
on) and interest, if any, on such series will be payable. If so provided in  the
Prospectus  Supplement, the  Place of  Payment for  a series  issuable solely as
Registered Securities will be New York  City, and the Company and the  Guarantor
will initially designate the office of the agent of the Trustee in New York City
as  an office where such principal, premium  and interest will be payable. If so
provided in the Prospectus Supplement, the  Company and the Guarantor will  also
initially  designate  the  corporate trust  office  of the  Trustee  in Atlanta,
Georgia as an additional office or agency for payment of the Debt Securities  of
such  series. Notwithstanding the foregoing, at the option of the Company or the
Guarantor, interest, if any, may be  paid on Registered Securities (1) by  check
mailed  to the person entitled thereto at such person's address appearing in the
Security Register  or (2)  by wire  transfer to  an account  located inside  the
United  States maintained  by the  person entitled  thereto as  specified in the
Security Register  (Sections 307  and 1002).  Unless otherwise  provided in  the
Prospectus  Supplement,  payment of  any installment  of interest  on Registered
Securities will be made to the person in whose name such Registered Security  is
registered at the close of business on the Regular Record Date for such interest
(Section 307).

    If  Debt Securities of a series are  issuable solely as Bearer Securities or
as both Registered Securities  and Bearer Securities and  if so provided in  the
applicable Prospectus Supplement, the Company and the Guarantor will be required
to  maintain an office or agency (1) in each Place of Payment outside the United
States at which, subject to any  applicable laws and regulations, the  principal
of  (and premium,  if any,  on) and  interest, if  any, on  such series  will be
payable and (2) in New  York City, for payments  with respect to any  Registered
Securities of such series (and for payments with respect to Bearer Securities of
such  series in the  limited circumstances described  below, but not otherwise);
provided that,  if  required  in  connection  with  any  listing  of  such  Debt
Securities  on a stock  exchange located outside the  United States, the Company
and the Guarantor will maintain an office or agency for such Debt Securities  in
any  city  located outside  the United  States required  by such  stock exchange
(Section 1002).  The initial  locations  of such  offices  or agencies  will  be
specified  in the applicable Prospectus Supplement. Unless otherwise provided in
the Prospectus Supplement, principal of (and  premium, if any) and interest,  if
any,    on   Bearer   Securities    may   be   paid    by   wire   transfer   to

                                       7
<PAGE>
an account maintained by the person entitled thereto with a bank located outside
the United States  (Sections 307  and 1002).  Unless otherwise  provided in  the
Prospectus  Supplement, payment  of any  installment of  interest on  any Bearer
Securities on or before maturity will be made only against surrender of  coupons
for  such interest installments as they  severally mature (Section 1001). Unless
otherwise provided in the Prospectus Supplement, no payment with respect to  any
Bearer  Security will  be made  at any office  or agency  of the  Company or the
Guarantor in the United States or by  check mailed to any address in the  United
States or by transfer to an account maintained with a bank located in the United
States;  provided that payments  of principal of  (and premium, if  any, on) and
interest, if any, on Bearer Securities payable  in U.S. dollars will be made  at
the  office or agency of the Company and  the Guarantor in New York City if (but
only if) payment of the  full amount thereof in U.S.  dollars at all offices  or
agencies  outside the United States maintained  by the Company and the Guarantor
is illegal  or  effectively precluded  by  exchange controls  or  other  similar
restrictions (Section 1002).

    The  Company and  the Guarantor may  from time to  time designate additional
offices or agencies, approve a  change in the location  of any office or  agency
and, except as provided above, rescind the designation of any office or agency.

    Unless  otherwise provided in the Prospectus Supplement, with respect to any
series of Debt Securities denominated or payable in one or more Currencies other
than U.S.  dollars, the  Company and  the Guarantor  will maintain  one or  more
Exchange  Rate  Agents for  the purpose  of  making any  exchange determinations
specified in the Prospectus Supplement (Sections 313 and 1002). Unless otherwise
provided in  the  Prospectus  Supplement,  all payments  of  principal  of  (and
premium,  if any, on) and interest, if any, on any Debt Security that is payable
in a Currency other than U.S. dollars will be made in U.S. dollars in the  event
that  such Currency  (1) is a  currency, and  it ceases to  be used  both by the
government of the  country that issued  the currency  and by a  central bank  or
other  public institutions of or within  the international banking community for
the settlement of transactions, (2)  is the ECU, and it  ceases to be used  both
within  the European Monetary  System and for the  settlement of transactions by
public institutions of or  within the European Communities  or (3) is any  other
currency  unit (or composite currency)  other than the ECU,  and it ceases to be
used for the purposes for which it was established (each of the events described
in clauses (1) through (3), a "Conversion Event") (Section 312).

    All moneys paid by the Company or  the Guarantor to the Trustee or a  Paying
Agent  for the payment of principal of (or  premium, if any, on) or interest, if
any, on  any Debt  Security that  remains  unclaimed for  two years  after  such
principal,  premium or interest  becomes due and  payable will be  repaid to the
Company or  the Guarantor,  as the  case may  be, and  the holder  of such  Debt
Security or any related coupon will (subject to applicable abandoned property or
similar  laws) thereafter look only to the  Company or the Guarantor for payment
thereof (Section 1003).

    Registered  Securities  of  any  series  will  be  exchangeable  for   other
Registered  Securities of the same series of any authorized denominations and of
a like aggregate principal amount. If  (but only if) provided in the  Prospectus
Supplement,  Bearer Securities of any series (with all unmatured coupons, except
as provided  below,  and  all  matured coupons  in  default)  may  be  similarly
exchanged  for  Registered  Securities  of the  same  series  of  any authorized
denominations. If so provided, Bearer  Securities of such series surrendered  in
exchange  for Registered Securities during the period  (1) on or after a Regular
Record Date and before the opening of business on the relevant Interest  Payment
Date or (2) on or after a Special Record Date and before the opening of business
on  the  related  proposed  date  for payment  of  Defaulted  Interest,  will be
surrendered without  the  coupon  relating  to such  Interest  Payment  Date  or
proposed  date for payment, and such interest or Defaulted Interest, as the case
may be, will  not be payable  in respect  of the Registered  Security issued  in
exchange  for such Bearer  Security, but will  be payable only  to the holder of
such coupon  when due  in accordance  with the  terms of  the Indenture.  Unless
otherwise  specified in the Prospectus Supplement, Bearer Securities will not be
issued in exchange for Registered Securities (Section 305).

                                       8
<PAGE>
    Registered Securities  of a  series  may be  presented for  registration  of
transfer  and Debt Securities of  a series may be  presented for exchange (1) at
each office or agency required to be maintained by the Company and the Guarantor
for payment of such series, as described above, and (2) at each other office  or
agency  that the Company and  the Guarantor may designate  from time to time for
such purposes. Registration of transfers and  exchanges will be effected if  the
transfer  agent is satisfied with the evidence  of ownership and identity of the
person making the  request and,  in the case  of Registered  Securities, if  the
transfer  form thereon is duly executed. No  service charge will be made for any
registration of transfer  or exchange of  Debt Securities, but  the Company  may
require  payment of any  tax or other governmental  charge payable in connection
therewith (Section 305).

    In the event of any redemption in part, the Company will not be required (1)
to register the transfer of or exchange  Debt Securities of any series during  a
period beginning at the opening of business 15 days before any selection of Debt
Securities  of that series to be redeemed and ending at the close of business on
the date the relevant notice of redemption  is mailed or published, as the  case
may  be, (2) to register the transfer  of or exchange any Registered Security or
portion thereof called for redemption, except the unredeemed portion, if any, of
a Registered  Security  being redeemed  in  part,  (3) to  exchange  any  Bearer
Security  called for redemption,  except to exchange such  Bearer Security for a
Registered Security  of  that  series  and like  tenor  that  is  simultaneously
surrendered  for redemption or (4)  to register the transfer  of or exchange any
Debt Security  that has  been surrendered  for repayment  at the  option of  the
holder,  except the portion, if  any, of such Debt Security  not to be so repaid
(Section 305).

CONSOLIDATION, MERGER AND SALE OF ASSETS

    Neither the Company nor the Guarantor may consolidate with or merge into any
other corporation or  other entity,  or convey  or transfer  its properties  and
assets  substantially as an entirety to any person, unless each of the following
conditions is satisfied:

        (1) Immediately  thereafter, no  Event of  Default (or  event that  with
    notice  or  lapse of  time,  or both,  would be  such)  with respect  to the
    Indenture Securities will have happened and be continuing.

        (2) The  corporation formed  by  such consolidation  or into  which  the
    Company  or the Guarantor is merged, or  the person to which such properties
    and assets will  have been  conveyed or transferred,  assumes the  Company's
    obligation  as to  the due  and punctual  payment of  the principal  of (and
    premium, if any, on)  and interest, if any,  on the Indenture Securities  or
    the  Guarantor's obligations under  the Guarantees, as the  case may be, and
    the performance and  observance of  every covenant  to be  performed by  the
    Company  or the Guarantor, as the case may be, under the Indenture, and will
    be organized under the laws of the United States, one of the States  thereof
    or  the District of Columbia; provided  that the requirements of this clause
    (2) will not apply to a transaction in which the Guarantor consolidates with
    or merges into the Company.

        (3) In  the  event of  any  such consolidation,  merger,  conveyance  or
    transfer,  the Indenture  provides that,  if any  Principal Facility  or any
    Restricted  Security  would  thereupon  become  subject  to  any  Lien,  the
    Indenture Securities (or the related Guarantees, as the case may be) will be
    secured,  as to such Principal Facility  or Restricted Security, equally and
    ratably with  (or  prior to)  the  Debt that  upon  the occurrence  of  such
    transaction  would become  secured by such  Lien, unless such  Lien could be
    created under  the  Indenture  without equally  and  ratably  securing  such
    Indenture Securities or Guarantees.

        (4)  The  Company  or the  Guarantor  has  delivered to  the  Trustee an
    officers'  certificate  and  opinion  of  counsel,  each  stating  that  the
    transaction complies with these conditions (Sections 801 and 803).

                                       9
<PAGE>
    In  the  event that  any  transaction described  in  and complying  with the
conditions listed in the immediately preceding paragraph occurs, the Company  or
the  Guarantor would be discharged from  all obligations and covenants under the
Indenture, and all obligations under the Indenture Securities or the Guarantees,
as the case may be, and could be dissolved and liquidated (Section 802).

    For the purpose of providing the  equal and ratable security referred to  in
clause (3) above, the principal amount of Indenture Securities outstanding under
the  Indenture that are Original Issue Discount Securities or Indexed Securities
will mean the amount that, at the  time of making such provision for such  equal
and  ratable security, would be  due and payable pursuant  to Section 502 of the
Indenture and the terms  of such Original Issue  Discount Securities or  Indexed
Securities upon an acceleration thereof (see "Events of Default" below), and the
extent  of  such equal  and ratable  security  will be  adjusted, to  the extent
permitted by law,  as and when  such amount  changes over time  pursuant to  the
terms of such Original Issue Discount Securities or Indexed Securities (Sections
502 and 803).

MODIFICATION AND WAIVER

    The Indenture permits the Company, the Guarantor and the applicable Trustee,
with  the  consent of  the  holders of  not less  than  a majority  in aggregate
principal amount  of  outstanding  Indenture  Securities  affected  thereby,  to
execute  supplemental  indentures  adding  any  provisions  to  or  changing  or
eliminating any provisions  of the  Indenture or  modifying the  rights of  such
holders,  except that no such supplemental indenture may, without the consent of
the holder of each outstanding Indenture Security affected thereby:

        (1) Change the Stated Maturity of the principal of (or premium, if  any,
    on)  or any installment of interest on any Indenture Security, or reduce the
    principal amount thereof (or  any premium, if any,  thereon) or the rate  of
    interest,  if any, thereon, or change any  obligation of the Company and the
    Guarantor  to  pay   Additional  Amounts  on   any  Indenture  Security   as
    contemplated  by  Section 1010  of  the Indenture,  or  change any  Place of
    Payment where  or the  Currency  in which  any  such principal,  premium  or
    interest  is payable, or  reduce the amount  of the principal  of an Indexed
    Security or  an Original  Issue  Discount Security  that  would be  due  and
    payable  upon  an acceleration  of maturity  thereof  or the  amount thereof
    provable in bankruptcy, or adversely affect the right of repayment, if  any,
    at  the option of the holder, or impair  the right to institute suit for the
    enforcement of any such payment on or after the Stated Maturity thereof  (or
    on or after any Redemption Date or Repayment Date).

        (2) Reduce the quorum and voting requirements at meetings of holders.

        (3)  Change in any manner adverse to the interests of the holders of the
    outstanding Indenture Securities the terms and conditions of the obligations
    of the Guarantor in respect of the due and punctual payment of the principal
    of (and  premium,  if any,  on)  and interest,  if  any, on  such  Indenture
    Securities.

        (4)  Reduce the percentage in  principal amount of outstanding Indenture
    Securities (or of  outstanding Indenture  Securities of any  series, as  the
    case  may  be), the  consent of  the holders  of which  is required  for any
    supplemental indenture or to  waive certain covenants  or Events of  Default
    under the Indenture (Section 902).

    The  holders  of a  majority in  aggregate  principal amount  of outstanding
Indenture Securities have the right to  waive compliance by the Company and  the
Guarantor with certain covenants contained in the Indenture (Section 1011).

    Modification  and amendment of the Indenture may be made by the Company, the
Guarantor and the  Trustee without the  consent of  any holder, for  any of  the
following  purposes: (1)  to evidence  the succession  of another  person to the
Company or the  Guarantor as  obligor under  the Indenture;  (2) to  add to  the
covenants  of the Company or the Guarantor for the benefit of the holders of any
series of Indenture  Securities and any  related coupons; (3)  to add Events  of
Default  for the benefit of the holders of any such series; (4) to add or change
any provisions of the Indenture to facilitate the

                                       10
<PAGE>
issuance of Bearer Securities; (5) to change or eliminate any provisions of  the
Indenture,  provided that any  such change or  elimination will become effective
only when there is  no Indenture Security outstanding  thereunder of any  series
that  is entitled to the benefit of such provisions; (6) to secure the Indenture
Securities outstanding under the Indenture or the related Guarantees pursuant to
the requirements of Section 803 or 1008  of the Indenture, or otherwise; (7)  to
establish the form or terms of Indenture Securities of any series or the related
Guarantees,  as  permitted by  Sections 201  and  301 of  the Indenture;  (8) to
provide for the acceptance of appointment  by a successor Trustee or  facilitate
the  administration of the trusts under the  Indenture by more than one Trustee;
(9) to close the  Indenture with respect to  the authentication and delivery  of
additional  series  of  Indenture  Securities  and  to  cure  any  ambiguity  or
inconsistency in such Indenture, provided such action does not adversely  affect
in  any material respect the interests of holders of Indenture Securities of any
series thereunder  and  related  coupons;  or (10)  to  supplement  any  of  the
provisions  of the  Indenture to  the extent  necessary to  permit or facilitate
defeasance and discharge of any series  of Indenture Securities and the  related
Guarantees  thereof, provided that such action  does not adversely affect in any
material respect the interests  of the holders of  the Indenture Securities  and
related coupons (Section 901).

    The  Indenture  provides  that in  determining  whether the  holders  of the
requisite principal amount of Indenture Securities of a series then  outstanding
have  given any  request, demand,  authorization, direction,  notice, consent or
waiver thereunder or whether a quorum is present at a meeting of holders of such
Indenture Securities, (1)  the principal  amount of an  Original Issue  Discount
Security  that  will be  deemed  to be  outstanding will  be  the amount  of the
principal thereof  that  would  be due  and  payable  as of  the  date  of  such
determination  upon  acceleration of  the  maturity thereof,  (2)  the principal
amount of  an Indenture  Security  denominated in  a  Currency other  than  U.S.
dollars  will  be the  U.S.  dollar equivalent,  determined  as of  the  date of
original issuance of such  Indenture Security, of  the principal amount  thereof
(or,  in  the case  of  an Original  Issue  Discount Security,  the  U.S. dollar
equivalent as of  such date  of original issuance  of the  amount determined  as
provided  in  clause (1)  above)  and (3)  the  principal amount  of  an Indexed
Security that may  be counted in  making such determination  or calculation  and
that  will be deemed outstanding for such purpose will be equal to the principal
face amount  of such  Indexed Security  at original  issuance, unless  otherwise
provided  with  respect  to  such Indenture  Security  pursuant  to  Section 301
(Section 101).

    The Indenture  contains  provisions for  convening  meetings of  holders  of
Indenture  Securities of  a series  if Indenture  Securities of  that series are
issuable as Bearer  Securities (Section 1501).  A meeting may  be called at  any
time by (1) the Trustee or (2) upon request by the Company, the Guarantor or the
holders  of  at  least  10%  in  aggregate  principal  amount  of  the Indenture
Securities of such  series outstanding, in  any such case  upon notice given  as
provided  in the Indenture (Section  1502). Except for any  consent that must be
given by the holder  of each Indenture Security  affected thereby, as  described
above,  any  resolution presented  at a  meeting (or  an adjourned  meeting duly
reconvened) at which a quorum is present may be adopted by the affirmative  vote
of  the holders of a majority in principal amount of the Indenture Securities of
that series; provided that any resolution  with respect to any request,  demand,
authorization,  direction, notice, consent,  waiver or other  action that may be
made, given or taken  only by the  holders of a  specified percentage, which  is
less  than a majority, in  principal amount of Indenture  Securities of a series
may be adopted at a meeting (or an adjourned meeting duly reconvened) at which a
quorum is  present by  the affirmative  vote of  the holders  of at  least  such
specified  percentage. Any resolution passed or decision taken at any meeting of
holders of Indenture  Securities of a  series duly held  in accordance with  the
Indenture  will be binding on all holders of Indenture Securities of that series
and any related coupons. The quorum at any meeting called to adopt a  resolution
will  be persons holding or  representing a majority in  principal amount of the
outstanding Indenture Securities of a series; provided that, if any action is to
be taken at such meeting  with respect to a consent  or waiver that may only  be
given by the holders of not less than a specified percentage in principal amount
of  the outstanding  Indenture Securities of  a series, the  persons entitled to
vote such specified percentage  will constitute a  quorum; and provided  further
that,

                                       11
<PAGE>
at the reconvening of any meeting adjourned for lack of a quorum, the holders of
25%  in principal amount of the outstanding  Indenture Securities of a series at
the time will constitute a quorum for the taking of any action set forth in  the
notice of the original meeting.

    Notwithstanding  the foregoing, if any action is to be taken at a meeting of
holders of Indenture Securities of a series with respect to any request, demand,
authorization, direction,  notice,  consent, waiver  or  other action  that  the
Indenture  expressly provides may  be made, given  or taken by  the holders of a
specified percentage in principal amount of all outstanding Indenture Securities
affected thereby, or of the  holders of that series  and one or more  additional
series,  then (1) there will  be no minimum quorum  requirement for such meeting
and (2) the  principal amount of  the outstanding Indenture  Securities of  that
series  that vote  in favor of  such request,  demand, authorization, direction,
notice,  consent,  waiver  or  other  action  will  be  taken  into  account  in
determining  whether  such  request, demand,  authorization,  direction, notice,
consent, waiver  or  other  action has  been  made,  given or  taken  under  the
Indenture (Section 1504).

EVENTS OF DEFAULT

    The  following are Events of Default with respect to any series of Indenture
Securities: (1) default in the payment  of any installment of interest upon  any
Indenture Security of such series when it becomes due and payable, continued for
30 days; (2) default in the payment of the principal of (or premium, if any, on)
any  Indenture Security of such series at  its maturity; (3) failure on the part
of the Company  or the Guarantor  to observe  or perform any  other covenant  or
agreement  contained  in  the  Indenture (other  than  a  covenant  or agreement
included in the  Indenture solely for  the benefit  of less than  all series  of
Indenture Securities or a covenant the default in the performance of which would
be  covered  by clause  (6)  below) for  60 days  after  written notice  of such
failure, requiring the  Company or the  Guarantor to remedy  the same, has  been
given  to the Company  and the Guarantor by  the Trustee or  to the Company, the
Guarantor and the Trustee by the holders of at least 25% in aggregate  principal
amount  of outstanding Indenture Securities; (4)  default under any indenture or
instrument under which the Company,  the Guarantor or any Restricted  Subsidiary
(other  than a Restricted Subsidiary principally engaged in business outside the
United States and Canada) has at the time outstanding indebtedness for  borrowed
money  or guarantees thereof in any individual instance in excess of $25,000,000
and, if not already matured in accordance with its terms, such indebtedness  has
been accelerated and such acceleration is not rescinded or annulled within three
Business  Days  after notice  thereof  has been  given  to the  Company  and the
Guarantor by the Trustee or to the Company, the Guarantor and the Trustee by the
holders of at least 25% in  aggregate principal amount of outstanding  Indenture
Securities  of such series; provided that, if, prior to the entry of judgment in
favor of the Trustee for payment of the Indenture Securities of such series, the
default under such  indenture or instrument  has been remedied  or cured by  the
Company,  the Guarantor or such Restricted  Subsidiary, or waived by the holders
of such indebtedness,  then the  Event of Default  under the  Indenture will  be
deemed  likewise to have been  remedied, cured or waived;  (5) certain events in
bankruptcy, insolvency or  reorganization; and  (6) any other  Event of  Default
included  in  the Indenture  for  the benefit  of  Indenture Securities  of such
series.

    If an Event of Default described in  clause (1), (2), (4) or (6) above  with
respect  to outstanding Indenture  Securities of any series  has occurred and is
continuing, the  Trustee  or the  holders  of not  less  than 25%  in  aggregate
principal  amount of  the outstanding  Indenture Securities  of that  series may
declare the principal amount (or, if the Indenture Securities of that series are
Original Issue Discount Securities  or Indexed Securities,  such portion of  the
principal  amount  as may  be  specified in  the terms  of  that series)  of all
outstanding Indenture  Securities  of such  series  to be  immediately  due  and
payable.  If  an Event  of  Default described  in clause  (3)  or (5)  above has
occurred and is continuing, the Trustee or  the holders of not less than 25%  in
principal  amount of  all the outstanding  Indenture Securities  may declare the
principal amount  (or,  if any  such  Indenture Securities  are  Original  Issue
Discount  Securities or Indexed Securities, such portion of the principal amount
as may be  specified in  the terms  of that series)  of all  of the  outstanding
Indenture  Securities to  be immediately due  and payable. However,  at any time
after  such  a   declaration  of  acceleration   with  respect  to   outstanding

                                       12
<PAGE>
Indenture Securities of a series (or of all outstanding Indenture Securities, as
the  case may be) has been made, but  before a judgment has been obtained by the
Trustee, the holders of a majority in principal amount of outstanding  Indenture
Securities  of such series  (or of all outstanding  Indenture Securities, as the
case may  be)  may,  subject  to certain  conditions,  rescind  and  annul  such
declaration  if all Events of Default  (other than the nonpayment of accelerated
principal, or a specified  portion thereof, premium, or  interest, if any)  with
respect   to  outstanding  Indenture  Securities  of  such  series  (or  of  all
outstanding Indenture Securities, as the case may be) have been cured or  waived
as  provided in  the Indenture  (Section 502).  The holders  of not  less than a
majority in aggregate principal amount  of the outstanding Indenture  Securities
of  a series (or  of all outstanding  Indenture Securities, as  the case may be)
have the right, subject to certain conditions and exceptions, to waive  defaults
other  than defaults in the payment of the principal of (or premium, if any, on)
or interest, if any, on  any Indenture Security of  such series and defaults  in
respect  of a covenant or  provision that cannot be  modified or amended without
the consent of the holder of each outstanding Indenture Security of such  series
affected  thereby (Sections  502 and 513).  Reference is made  to the Prospectus
Supplement relating to  any series of  Debt Securities that  are Original  Issue
Discount Securities or Indexed Securities for the particular provisions relating
to acceleration of a portion of the principal amount thereof upon the occurrence
and the continuation of an Event of Default.

    No  holder of any  Indenture Security of  any series will  have any right to
institute any proceeding with respect to the Indenture, or for any remedy  under
the Indenture, unless (1) such holder has previously given written notice to the
Trustee  of  a  continuing  Event  of  Default  with  respect  to  the Indenture
Securities of  such  series,  (2) the  holders  of  at least  25%  in  aggregate
principal  amount of outstanding Indenture Securities of such series in the case
of any Event of Default described in clause  (1), (2), (4) or (6) above, or  the
holders  of  at  least 25%  in  aggregate  principal amount  of  all outstanding
Indenture Securities in the case of any Event of Default described in clause (3)
or (5) above,  have made a  written request and  offered reasonable security  or
indemnity  to  the Trustee  to institute  such proceeding,  (3) the  Trustee has
failed to institute any such proceeding within 60 days after its receipt of such
notice, request and offer  and (4) no direction  inconsistent with such  written
request  has been given to the Trustee  during such 60-day period by the holders
of a majority in aggregate principal amount of outstanding Indenture  Securities
of such series (or of all outstanding Indenture Securities, as the case may be).
No  one or more of such  holders will have any right  under any provision of the
Indenture to affect,  disturb or prejudice  the rights of  any other holders  of
outstanding  Indenture Securities of the same series (in the case of an Event of
Default described in  clause (1),  (2), (4)  or (6)  above), or  holders of  all
outstanding  Indenture Securities (in the case  of an Event of Default described
in clause (3) or (5) above), or to obtain preference or priority over any  other
holders,  or to  enforce any  right under  the Indenture,  except in  the manner
provided in the  Indenture and  for the  equal and  ratable benefit  of all  the
holders  of outstanding Indenture Securities of the  same series (in the case of
an Event of Default described in clause (1), (2), (4) or (6) above), or  holders
of  all outstanding  Indenture Securities  (in the case  of an  Event of Default
described in clause (3) or (5) above) (Section 507).

    Subject to provisions relating to the duties of the Trustee in case an Event
of Default has occurred and is continuing, the Trustee is under no obligation to
exercise any of  the rights  or powers  under the  Indenture at  the request  or
direction  of  any  holders unless  such  holders  have offered  to  the Trustee
reasonable security or indemnity (Section 602  and TIA Section 315). Subject  to
such  provision for the  indemnification of the  Trustee and certain limitations
contained in the  Indenture, the holders  of a majority  in principal amount  of
outstanding  Indenture Securities of  a series (or  of all outstanding Indenture
Securities, as the case may be) will  have the right to direct the time,  method
and  place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred on the Trustee (Section 512).

    The Trustee will, within 90 days after the occurrence of a default  actually
known  to it with respect to the outstanding Indenture Securities of any series,
give notice to  all holders  of such series  of all  uncured defaults;  provided
that,  except in  the case  of default in  the payment  of the  principal of (or

                                       13
<PAGE>
premium, if any, on) or interest, if any, on any outstanding Indenture  Security
of  such series, the Trustee will be  protected in withholding such notice if it
determines in good faith that the withholding of such notice is in the interests
of such  holders; and  provided further  that, in  the case  of a  default  with
respect  to the outstanding  Indenture Securities of  the character specified in
clause (3) of the definition of Events of Default, no such notice will be  given
until at least 30 days after the occurrence thereof (Section 601).

    The  Company and the Guarantor  will be required to  furnish annually to the
Trustee a statement as to  the fulfillment by the  Company and the Guarantor  of
all of their respective obligations under the Indenture (Section 1004).

DEFEASANCE AND COVENANT DEFEASANCE

    The  Indenture provides that the Company may elect either (1) to defease and
be discharged, for itself and the  Guarantor, from any and all obligations  with
respect  to all or a  portion of the Indenture Securities  of any series and any
related coupons (except for  the obligations (a) to  pay Additional Amounts,  if
any;  (b) to register the transfer of  or exchange such Indenture Securities and
any related coupons; (c) to replace  temporary or mutilated, destroyed, lost  or
stolen  Indenture  Securities of  such series  and any  related coupons;  (d) to
maintain an office  or agency in  respect of such  Indenture Securities and  any
related coupons; and (e) to hold moneys for payment in trust) ("defeasance"); or
(2)  to be  released, for  itself and the  Guarantor, from  its obligations with
respect to such outstanding Indenture  Securities and any related coupons  under
Sections  1008 and 1009 of the Indenture (being the restrictions described above
under "Liens" and  "Sale and  Leaseback Transactions",  respectively, under  the
heading  "Certain Covenants") or,  if so provided  in the Prospectus Supplement,
its and the Guarantor's obligations with respect to any other covenant, and  any
omission  to comply with  such obligations will  not constitute a  default or an
Event of  Default with  respect to  such Indenture  Securities and  any  related
coupons ("covenant defeasance"), in the case of either clause (1) or clause (2),
upon  the irrevocable deposit by  the Company or the  Guarantor with the Trustee
(or other qualifying trustee), in  trust, of (i) an  amount, in the Currency  in
which  such Indenture Securities  and any related coupons  are then specified as
payable at  Stated  Maturity, (ii)  Government  Obligations (as  defined  below)
applicable  to  such Indenture  Securities and  any  related coupons  (with such
applicability being  determined on  the  basis of  the  Currency in  which  such
Indenture  Securities are  then specified as  payable at  Stated Maturity) that,
through the payment of  principal and interest in  accordance with their  terms,
will  provide money in an  amount, or (iii) a  combination thereof in an amount,
sufficient to pay the principal  of (and premium, if  any, on) and interest,  if
any,  on such  Indenture Securities and  any related coupons,  and any mandatory
sinking fund or analogous payments thereon, on the scheduled due dates therefor.

    Such a trust may only be established if, among other things, the Company has
delivered to the Trustee an opinion of counsel to the effect that the holders of
such Indenture Securities  and any  related coupons will  not recognize  income,
gain  or loss for United States federal income  tax purposes as a result of such
defeasance or covenant defeasance and will  be subject to United States  federal
income  tax on the  same amounts, in  the same manner  and at the  same times as
would have  been the  case if  such defeasance  or covenant  defeasance had  not
occurred,  and such opinion, in  the case of defeasance  under clause (1) above,
must refer to and be  based upon a ruling of  the Internal Revenue Service or  a
change  in applicable United  States federal income tax  law occurring after the
date of the Indenture (Article 14).

    Unless  otherwise  provided   in  the   applicable  Prospectus   Supplement,
"Government Obligations" means securities that are (1) direct obligations of the
government  that  issued the  Currency in  which the  Indenture Securities  of a
series are payable or  (2) obligations of a  person controlled or supervised  by
and  acting as an agency  or instrumentality of such  government, the payment of
which obligations is  unconditionally guaranteed  by such  government, that,  in
either case, are full faith and credit obligations of such government payable in
such  Currency and are  not callable or  redeemable at the  option of the issuer
thereof. Such term will also  include a depository receipt  issued by a bank  or
trust company

                                       14
<PAGE>
as  custodian  with respect  to  any such  Government  Obligation or  a specific
payment of principal of  or interest on any  such Government Obligation held  by
such  custodian for the account of the  holder of a depository receipt; provided
that (except as required by  law) such custodian is  not authorized to make  any
deduction  from the amount payable to the holder of such depository receipt with
respect to any  amount received by  the custodian in  respect of the  Government
Obligation  for the specific payment of  interest or principal of the Government
Obligation evidenced by such depository receipt (Section 101).

    Unless otherwise  provided  in  the Prospectus  Supplement,  if,  after  the
Company  or the Guarantor has deposited funds, Government Obligations or both to
effect defeasance with  respect to any  Indenture Securities (1)  the holder  of
such an Indenture Security is entitled to, and does, elect pursuant to the terms
of  such Indenture Security to receive payment  in a Currency other than that in
which such  deposit  has  been  made  or (2)  a  Conversion  Event  occurs,  the
indebtedness represented by such Indenture Security and any related coupons will
be  deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium,  if any, on) and interest, if any,  on
such  Indenture  Security as  they become  due  out of  the proceeds  yielded by
converting (from time to  time in the  case of such an  election) the amount  so
deposited  into the Currency in which such Indenture Security becomes payable as
a result of such  election or such  cessation of usage  based on the  applicable
Market  Exchange  Rate  (as  defined  in  the  Indenture  or  in  the Prospectus
Supplement) for such Currency in effect on the second Business Day prior to each
payment date (with respect to  such an election) or  (as nearly as feasible)  in
effect  at  the time  of  such a  cessation  of usage  (with  respect to  such a
cessation of usage) (Section 1405).

    In the event  the Company effects  covenant defeasance with  respect to  any
Indenture  Securities and any related coupons  and such Indenture Securities and
coupons are declared due and payable because  of the occurrence of any Event  of
Default other than (a) an Event of Default described in clause (3) under "Events
of  Default" with  respect to  Sections 1008  and 1009  of the  Indenture (which
Sections would no longer be applicable to such Indenture Securities or  coupons)
or  (b) an  Event of  Default described in  clause (3)  or (6)  under "Events of
Default" with  respect  to  any  other  covenant as  to  which  there  has  been
defeasance,  the realizable  value of  the money  and Government  Obligations on
deposit with the Trustee may not be  sufficient to pay amounts due on such  Debt
Securities and coupons at the time of the acceleration resulting from such Event
of  Default,  in  that the  required  deposit  with the  Trustee  is  based upon
scheduled cash flows rather  than market value, which  will vary depending  upon
interest  rates and other factors. However,  the Company and the Guarantor would
remain liable to  make payment  of such  shortfall amounts  due at  the time  of
acceleration.

    The  Prospectus  Supplement may  further  describe the  provisions,  if any,
permitting such defeasance or  covenant defeasance, including any  modifications
to  the provisions described above, with  respect to the Indenture Securities of
or within a particular series, any related coupons and the related Guarantees.

CERTAIN COVENANTS

    LIENS

    The Indenture provides that each of  the Company and the Guarantor will  not
itself,  and  will not  permit any  of its  Restricted Subsidiaries  to, create,
incur, issue, assume or guarantee  any Debt secured by  a Lien on any  Principal
Facility  or on  any Restricted  Security without  in any  such case effectively
providing that the Indenture  Securities issued thereunder (in  the case of  the
Company), the related Guarantees (in the case of the Guarantor) or the Indenture
Securities  and Guarantees (in the case of a Restricted Subsidiary) (and, at the
option of the Company or  the Guarantor, as the case  may be, any other Debt  of
the  Company, the  Guarantor or any  such Restricted  Subsidiary ranking equally
with the  Indenture  Securities  or  Guarantees  or  the  senior  Debt  of  such
Restricted  Subsidiary, as the case may be)  will be secured equally and ratably
with or prior to such secured  Debt, except that the foregoing restriction  will
not apply to:

        (1)  Liens existing as of the date  of the first issuance by the Company
    of any such Indenture Securities.

        (2) Liens on property or  assets of, or on any  shares of stock or  Debt
    issued  by, any corporation existing at  the time such corporation becomes a
    Restricted Subsidiary.

                                       15
<PAGE>
        (3) Liens  in favor  of the  Company, the  Guarantor or  any  Restricted
    Subsidiary.

        (4)  Liens on any Principal Facility  or Restricted Security existing at
    the time of acquisition thereof or certain purchase money Liens.

        (5) Liens on any  Principal Facility to  secure all or  any part of  the
    cost   of  exploration,  drilling,   development,  operation,  construction,
    alteration, repair  or improvement  of all  or any  part of  such  Principal
    Facility or to secure certain Debt incurred for the purpose of financing all
    or any part of such cost.

        (6)  Any extension, renewal, substitution  or replacement (or successive
    extensions, renewals, substitutions or replacements),  in whole or in  part,
    of any Lien referred to in the foregoing clauses (1) through (5).

Notwithstanding  the  above,  the  Company,  the  Guarantor  and  any Restricted
Subsidiary may, without securing such Indenture Securities, Guarantees or senior
Debt, create, incur,  issue, assume  or guarantee Debt  secured by  a Lien  that
would  otherwise be subject to the  foregoing restrictions, provided that, after
giving effect thereto, the aggregate principal amount of such secured Debt  then
outstanding,  whenever  created, incurred,  issued,  assumed or  guaranteed (not
including Debt  secured  by Liens  permitted  or excepted  under  the  foregoing
exceptions)  plus all  Attributable Debt of  the Company, the  Guarantor and the
Restricted Subsidiaries in respect of sale and leaseback transactions  involving
Principal  Facilities, entered into after the date  of the first issuance by the
Company of  any  such  Indenture  Securities  (other  than  sale  and  leaseback
transactions  described in clause (2)  or (3) of the  section entitled "Sale and
Leaseback Transactions"),  would not  exceed 10%  of Consolidated  Net  Tangible
Assets (Section 1008).

    SALE AND LEASEBACK TRANSACTIONS

    The  Indenture further provides  that each of the  Company and the Guarantor
will not itself,  and will  not permit any  of its  Restricted Subsidiaries  to,
enter  into any sale and  leaseback transaction (except a  lease for a temporary
period, including renewals, not exceeding three years and except leases with the
Company, the Guarantor or any such Restricted Subsidiary) covering any Principal
Facility that has  been or  is to  be sold or  transferred by  the Company,  the
Guarantor or such Restricted Subsidiary, unless (1) the Attributable Debt of the
Company,  the Guarantor and  the Restricted Subsidiaries  in respect thereof and
all  other  sale  and  leaseback  transactions  covering  Principal  Facilities,
whenever entered into (other than such sale and leaseback transactions as are in
compliance  with  the  provisions  described  in  clause  (2)  or  (3)  of  this
paragraph), plus the  aggregate principal  amount of  Debt secured  by Liens  on
Principal  Facilities or on  Restricted Securities then  outstanding (other than
Debt secured  by Liens  permitted  or excepted  without securing  the  Indenture
Securities outstanding thereunder and the related Guarantees and other than Debt
if  such Indenture Securities are  secured equally and ratably  with or prior to
such Debt), would not exceed 10% of  Consolidated Net Tangible Assets or (2)  an
amount  ("Designated Amount") equal to  the greater of the  net proceeds of such
sale or the fair market value of  such Principal Facility (as determined by  the
Company  or the Guarantor, as the case may  be) is applied within 120 days after
the transaction to the retirement of Funded Debt of the Company or the Guarantor
(other than at  maturity or pursuant  to any mandatory  sinking fund payment  or
mandatory  prepayment  provision),  except  that the  amount  to  be  applied to
retirement of Funded Debt of the Company or the Guarantor will be reduced by (a)
the aggregate  principal amount  of  any such  Indenture Securities  called  for
redemption  by the Company  within 120 days after  such transaction or delivered
within such 120-day period  to the Trustee for  retirement and cancellation  and
(b)  the aggregate  principal amount of  Funded Debt, other  than such Indenture
Securities, voluntarily retired by the Company or the Guarantor within 120  days
after  such transaction,  or (3) the  Company, the Guarantor  or such Restricted
Subsidiary, within a period commencing 12  months prior to and ending 12  months
after  the date of  the sale or transfer  in respect of  such sale and leaseback
transaction, has expended  or reasonably  expects to expend  within such  period
moneys  to acquire or  construct any Principal Facility  or Facilities, in which
case the Company,  the Guarantor or  such Restricted Subsidiary  may enter  into
such  sale  and leaseback  transaction,  but only  if  the Designated  Amount in
respect thereof is less than or equal to such moneys expended or to be  expended
within such period (Section 1009).

    DEFINITIONS

    "ATTRIBUTABLE  DEBT"   means,  as to  any particular  lease under  which any
person is at the time liable, at any  date as of which the amount thereof is  to

depreciation  reserves) on the date as of  which the determination is being made
exceeds 1% of  Consolidated Net Tangible  Assets, other than  any such plant  or
warehouse or any portion thereof (together with such land and fixtures) that, in
the  opinion of  the Board  of Directors  of the  Guarantor, is  not of material

BOOK-ENTRY DEBT SECURITIES

    Debt Securities of a  series (and the related  Guarantees) may be issued  in
whole  or in  part in the  form of  one or more  Global Securities  that will be
deposited with,  or on  behalf of,  a depository  identified in  the  Prospectus
Supplement  relating to such  series. Global Securities may  be issued in either
registered or bearer  form and  in either  temporary or  permanent form.  Unless
otherwise  provided in  the Prospectus Supplement,  Debt Securities  of a series
(and the related Guarantees)  that are represented by  a Global Security may  be
issued  in any denomination, and will be issued in registered form only, without
coupons. Payments of  principal of (and  premium, if any,  on) and interest,  if
any,  on Debt Securities of such series represented by a Global Security will be
made by the Company or the Trustee to the depository.

    The Company anticipates that any  Global Securities will be deposited  with,
or  on behalf of, The Depository Trust Company ("DTC"), New York, New York, that
such Global Securities will be registered in the name of DTC's nominee, and that
the following provisions will apply to the depository arrangements with  respect
to  any such Global Securities. Additional  or differing terms of the depository
arrangement will be described in  the Prospectus Supplement relating to  Offered
Debt Securities issued in the form of Global Securities.

    So  long as DTC or its nominee is the registered owner of a Global Security,
DTC or its nominee, as  the case may be, will  be considered the sole holder  of
the  Debt Securities represented by such  Global Security for all purposes under
the Indenture. Except as  described below, owners of  beneficial interests in  a
Global Security will not be entitled to have Debt Securities represented by such
Global  Security registered in their  names, will not receive  or be entitled to
receive physical delivery of Debt Securities  in certificated form and will  not
be  considered the owners or holders of Debt Securities under the Indenture. The
laws of some states require that certain purchasers of securities take  physical
delivery  of such  securities in certificated  form; accordingly,  such laws may
limit the transferability of beneficial interests in a Global Security.

    If DTC is at any  time unwilling or unable to  continue as depository and  a
successor  depository is not  appointed by the Company  within 90 days following
notice to the  Company, the  Company will  issue individual  Debt Securities  in
certificated  form  in  exchange for  the  Global Securities.  In  addition, the
Company may at any time, and in  its sole discretion, determine not to have  any
Debt  Securities of one or more series  represented by Global Securities and, in
such event, will issue individual Debt Securities of such series in certificated
form in exchange for  the relevant Global Securities.  In any such instance,  an
owner of a beneficial interest in a Global Security will be entitled to physical
delivery  of individual Debt Securities in  certificated form equal in principal
amount to  such  beneficial  interest  and  to  have  such  Debt  Securities  in
certificated form registered in its name.

    The following is based on information furnished by DTC:

        DTC  will act as securities depository for the Debt Securities. The Debt
    Securities will be issued as  fully registered securities registered in  the
    name  of Cede &  Co. (DTC's partnership nominee).  One fully registered Debt
    Security certificate will  be issued with  respect to each  $150 million  of
    principal  amount  of the  Debt Securities  of a  series, and  an additional
    certificate will be issued with respect to any remaining principal amount of
    such series.

        DTC is  a limited-purpose  trust company  organized under  the New  York
    Banking  Law, a  "banking organization" within  the meaning of  the New York
    Banking  Law,  a  member  of   the  Federal  Reserve  System,  a   "clearing
    corporation" within the meaning of the New York Uniform Commercial Code, and
    a  "clearing agency" registered pursuant to the provisions of Section 17A of
    the   Exchange   Act.   DTC   holds   securities   that   its   participants
    ("Participants") deposit with DTC.

                                       18
<PAGE>
    DTC  also  facilitates  the  settlement  among  Participants  of  securities
    transactions, such as transfers and pledges, in deposited securities through
    electronic  computerized  book-entry  changes  in  Participants'   accounts,
    thereby   eliminating  the   need  for   physical  movement   of  securities
    certificates. Direct Participants  include securities  brokers and  dealers,
    banks,   trust   companies,   clearing   corporations   and   certain  other
    organizations ("Direct  Participants"). DTC  is  owned by  a number  of  its
    Direct  Participants and by the New  York Stock Exchange, Inc., the American
    Stock Exchange, Inc.  and the  National Association  of Securities  Dealers,
    Inc. Access to the DTC system is also available to others such as securities
    brokers  and  dealers,  banks  and trust  companies  that  clear  through or
    maintain a custodial relationship with a Direct Participant, either directly
    or indirectly ("Indirect Participants"). The rules applicable to DTC and its
    Participants are on file with the SEC.

        Purchases of Debt  Securities under the  DTC system must  be made by  or
    through  Direct  Participants,  which will  receive  a credit  for  the Debt
    Securities on DTC's records. The ownership interest of each actual purchaser
    of each Debt Security ("Beneficial Owner") is in turn to be recorded on  the
    Participants'   records.  A  Beneficial  Owner   will  not  receive  written
    confirmation from DTC of its purchase, but such Beneficial Owner is expected
    to receive a written confirmation  providing details of the transaction,  as
    well  as periodic statements  of its holdings,  from the Participant through
    which such  Beneficial  Owner entered  into  the transaction.  Transfers  of
    ownership  interests in  Debt Securities are  to be  accomplished by entries
    made on the  books of Participants  acting on behalf  of Beneficial  Owners.
    Beneficial Owners will not receive certificates representing their ownership
    interests in Debt Securities, except in the event that use of the book-entry
    system for the Debt Securities is discontinued.

        To   facilitate  subsequent  transfers,  the  Debt  Securities  will  be
    registered in the name of DTC's partnership nominee, Cede & Co. The  deposit
    of the Debt Securities with DTC and their registration in the name of Cede &
    Co.  will  effect  no  change  in beneficial  ownership.  DTC  will  have no
    knowledge of  the  actual Beneficial  Owners  of the  Debt  Securities;  DTC
    records  will reflect only the identity  of the Direct Participants to whose
    accounts Debt  Securities  are  credited,  which  may  or  may  not  be  the
    Beneficial  Owners.  The Participants  will  remain responsible  for keeping
    account of their holdings on behalf of their customers.

        Delivery  of  notices  and  other   communications  by  DTC  to   Direct
    Participants, by Direct Participants to Indirect Participants, and by Direct
    and   Indirect  Participants  to  Beneficial  Owners  will  be  governed  by
    arrangements among them, subject to any statutory or regulatory requirements
    as may be in effect from time to time.

        Neither DTC nor Cede & Co. will consent or vote with respect to the Debt
    Securities. Under  its usual  procedures,  DTC mails  a proxy  (an  "Omnibus
    Proxy") to the issuer as soon as possible after the record date. The Omnibus
    Proxy  assigns  Cede &  Co.'s consenting  or voting  rights to  those Direct
    Participants to  whose accounts  the  Debt Securities  are credited  on  the
    record date (identified on a list attached to the Omnibus Proxy).

        Principal,  premium and interest payments on the Debt Securities will be
    made to DTC. DTC's  practice is to credit  Direct Participants' accounts  on
    the  payable date in  accordance with their respective  holdings as shown on
    DTC's records unless  DTC has  reason to believe  that it  will not  receive
    payment  on the payable date. Payments  by Participants to Beneficial Owners
    will be governed by standing instructions and customary practices, as is the
    case with securities held  for the accounts of  customers in bearer form  or
    registered  in  "street  name",  and  will  be  the  responsibility  of such
    Participant and not of DTC, the Paying Agent or the Company, subject to  any
    statutory  or regulatory requirements as may be in effect from time to time.
    Payment of  principal and  interest  to DTC  is  the responsibility  of  the
    Company  or  the  Paying  Agent, disbursement  of  such  payments  to Direct
    Participants will be  the responsibility  of DTC, and  disbursement of  such
    payments  to the Beneficial Owners will  be the responsibility of Direct and
    Indirect Participants.

        DTC may discontinue providing its services as securities depository with
    respect to the Debt  Securities at any time  by giving reasonable notice  to
    the Company or the Paying Agent. Under such circumstances, in the event that
    a   successor  securities   depository  is  not   appointed,  Debt  Security
    certificates are required to be printed and delivered.

                                       19
<PAGE>
        The Company may decide  to discontinue use of  the system of  book-entry
    transfers through DTC (or a successor securities depository). In that event,
    Debt Security certificates will be printed and delivered.

    The  information in this section concerning  DTC and DTC's book-entry system
has been  obtained  from  sources  (including DTC)  that  the  Company  and  the
Guarantor  believe to  be reliable,  but the Company  and the  Guarantor take no
responsibility for the accuracy thereof.

    Unless  stated  otherwise  in  the  applicable  Prospectus  Supplement,  the
underwriters  or agents with respect to Offered Debt Securities issued as Global
Securities will be Direct Participants in DTC.

    None of the Company, the Guarantor, any underwriter or agent, the Trustee or
any Paying Agent will have any responsibility or liability for any aspect of the
records relating to  or payments made  on account of  beneficial interests in  a
Global  Security,  or  for  maintaining, supervising  or  reviewing  any records
relating to such beneficial interests.

CONCERNING THE TRUSTEE

    NationsBank of  Georgia,  National  Association, Atlanta,  Georgia,  is  the
Trustee  under the Indenture. The Trustee is  expected to serve as warrant agent
(see  "Description  of  Warrants").  Grace  also  maintains  customary   banking
relationships  with the Trustee  and its banking  affiliates, one of  which is a
party to a revolving credit agreement with Grace.

                            DESCRIPTION OF WARRANTS

    The Company may issue  Warrants either separately  or together with  Offered
Debt  Securities. Each issue of Warrants will  be made under a warrant agreement
(each a "Warrant Agreement") to be entered into between the Company and the bank
or trust company specified in  the Prospectus Supplement ("Warrant Agent").  The
Warrant  Agent is expected to be the  Trustee. The form of the Warrant Agreement
has been filed with  the SEC as  an exhibit to  the Registration Statement.  The
following  summary of the material provisions  of the Warrant Agreement does not
purport to be  complete and  is subject  to, and  qualified in  its entirety  by
reference  to, the Warrant Agreement, including the definitions of certain terms
therein, and to the specific terms of  the Warrants set forth in the  Prospectus
Supplement.

GENERAL

    Reference is made to the Prospectus Supplement for the specific terms of the
Warrants  in respect of which this  Prospectus and the Prospectus Supplement are
being delivered, including the following:

        (1) The title and aggregate number of such Warrants.

        (2) The offering price of such Warrants.

        (3) The title, aggregate  principal amount and  terms of the  Underlying
    Debt  Securities issuable upon exercise of such Warrants (as specified under
    "Description of Debt Securities and Guarantees -- General").

        (4) The principal  amount of  Underlying Debt  Securities issuable  upon
    exercise  of each such Warrant, and the  price, or the manner of determining
    the price,  at  which such  principal  amount  may be  purchased  upon  such
    exercise.

        (5)  The time or times at which, or period or periods during which, such
    Warrants may be exercised and the expiration date of such Warrants.

        (6) The terms of any right of the Company to redeem such Warrants.

        (7) Whether  such  Warrants are  to  be  issued with  any  Offered  Debt
    Securities  and, if so,  the title, aggregate principal  amount and terms of
    such Offered  Debt  Securities  (as specified  under  "Description  of  Debt
    Securities and Guarantees -- General") and the number of such Warrants to be
    issued with each $1,000 principal amount of such Offered Debt Securities (or
    such other principal amount as may be established).

        (8)  The date, if any, on and after which such Warrants and such Offered
    Debt Securities will be separately transferable.

                                       20
<PAGE>
    If applicable, the  Prospectus Supplement  will also  set forth  information
concerning  any Offered Debt Securities offered  thereby and a discussion of any
relevant federal income tax considerations.

    Certificates representing Warrants ("Warrant Certificates") may be issued in
registered or bearer form, or both,  as set forth in the Prospectus  Supplement,
and   will   be  exchangeable   for  new   Warrant  Certificates   of  different
denominations. No service  charge will  be made  for any  permitted transfer  or
exchange of Warrant Certificates, but the Company may require payment of any tax
or  other governmental charge  payable in connection  therewith. Warrants may be
exercised at the corporate trust office of the Warrant Agent or any other office
indicated in the Prospectus Supplement.

EXERCISE OF WARRANTS

    Each Warrant will  entitle the  holder thereof  to purchase  such amount  of
Underlying  Debt Securities  at the exercise  price set forth  in, or calculable
from, the Prospectus Supplement  relating to such Warrants.  After the close  of
business  on the  applicable expiration  date, unexercised  Warrants will become
void.

    Warrants may be exercised by payment to the Warrant Agent of the  applicable
exercise price and by delivery to the Warrant Agent of the information specified
on  the Warrant Certificate. Warrants will be deemed to have been exercised upon
receipt of the  exercise price,  subject to the  receipt by  the Warrant  Agent,
within five business days thereafter, of the Warrant Certificate or Certificates
evidencing  such Warrants. Upon  receipt of such  payment and properly completed
Warrant Certificates at the corporate trust  office of the Warrant Agent or  any
other  office  indicated in  the applicable  Prospectus Supplement,  the Company
will, as soon as practicable, deliver  the amount of Underlying Debt  Securities
purchased  upon such exercise. If fewer than  all of the Warrants represented by
any Warrant Certificate are exercised, a new Warrant Certificate will be  issued
for  the unexercised Warrants. The  holder of a Warrant  will be required to pay
any tax or other governmental charge that may be imposed in connection with  any
transfer  involved in the issuance of  Underlying Debt Securities purchased upon
such exercise.

MODIFICATIONS

    The Warrant Agreement and the  terms of the Warrants  may be amended by  the
Company  and  the Warrant  Agent, without  the  consent of  any holder,  for the
purpose of curing any ambiguity, or  of curing, correcting or supplementing  any
defective  or inconsistent provision  contained therein, or  in any other manner
that the Company deems necessary or  desirable and that will not materially  and
adversely affect the interests of the holders of the Warrants.

    The  Company and  the Warrant  Agent also  may modify  or amend  the Warrant
Agreement and terms of the Warrants with the consent of the holders of not  less
than  a majority in number of the then outstanding unexercised Warrants affected
thereby; provided that no  such modification or  amendment that accelerates  the
expiration date, increases the exercise price, reduces the number of outstanding
Warrants  the consent of  the holders of  which is required  for modification or
amendment of the Warrant  Agreement or the terms  of the Warrants, or  otherwise
materially  and adversely affects the rights of  the holders of Warrants, may be
made without the consent of each holder affected thereby.

NO RIGHTS AS HOLDERS OF UNDERLYING DEBT SECURITIES

    Holders of Warrants are  not entitled, by virtue  of being such holders,  to
payment  of principal of  (or premium, if any,  on) or interest,  if any, on the
related Underlying Debt Securities or to exercise any other rights whatsoever as
holders of such Underlying Debt Securities.

                              PLAN OF DISTRIBUTION

    Offered Securities may be sold directly to one or more purchasers or through
underwriters, dealers or agents.

    If underwriters are used in an  offering of Offered Securities, the name  of
each  managing  underwriter and  any  other underwriters  and  the terms  of the
transaction, including any underwriting  discounts and other items  constituting
compensation  of the underwriters and dealers, if  any, will be set forth in the
Prospectus Supplement relating to such offering, and the Offered Securities will
be acquired by the underwriters  for their own accounts  and may be resold  from
time to time in one or

                                       21
<PAGE>
more transactions, including negotiated transactions, at a fixed public offering
price  or at varying prices  determined at the time  of sale. Any initial public
offering price and any discounts or concessions allowed or reallowed or paid  to
dealers may be changed from time to time.

    Only  underwriters named  in a  Prospectus Supplement  will be  deemed to be
underwriters in connection with the Offered Securities described therein; a firm
not so named will have no  direct or indirect participation in the  underwriting
of   such  Offered  Securities,  although  such  firm  may  participate  in  the
distribution of such Offered  Securities under circumstances  entitling it to  a
dealer's   commission.  It  is  anticipated   that  any  underwriting  agreement
pertaining to  any  Offered Securities  will  (1) entitle  the  underwriters  to
indemnification  by  the Company  against  certain civil  liabilities  under the
Securities Act, (2)  provide that the  obligations of the  underwriters will  be
subject  to certain conditions  precedent and (3)  provide that the underwriters
will be obligated to purchase all Offered Securities (other than any subject  to
Delayed Delivery Contracts) if any are purchased.

    If  a dealer is used in an  offering of Offered Securities, the Company will
sell such Offered Securities  to the dealer, as  principal. The dealer may  then
resell  such Offered Securities to the public at varying prices to be determined
by such dealer at the time  of resale. The name of  the dealer and the terms  of
the transaction will be set forth in the Prospectus Supplement relating thereto.

    If  an agent is used in an offering of Offered Securities, the agent will be
named, and  the  terms of  the  agency will  be  set forth,  in  the  Prospectus
Supplement  relating  thereto.  Unless otherwise  indicated  in  such Prospectus
Supplement, an agent  will act on  a best efforts  basis for the  period of  its
appointment.

    Dealers  and agents  named in  a Prospectus Supplement  may be  deemed to be
underwriters  (within  the  meaning  of  the  Securities  Act)  of  the  Offered
Securities described therein and, under agreements that may be entered into, may
be  entitled to indemnification by the Company and the Guarantor against certain
civil liabilities under the Securities Act. Underwriters, dealers and agents may
be customers of, engage  in transactions with or  perform services for Grace  in
the ordinary course of business.

    Offers  to purchase Offered  Securities may be  solicited, and sales thereof
may be made, by the Company  directly to institutional investors or others,  who
may  be deemed to be underwriters within  the meaning of the Securities Act with
respect to any resales thereof. The terms  of any such offers will be set  forth
in the Prospectus Supplement relating thereto.

    If  so indicated  in the Prospectus  Supplement, the  Company will authorize
underwriters or  other  agents of  the  Company  to solicit  offers  by  certain
institutional investors to purchase Offered Securities from the Company pursuant
to  contracts providing for payment and delivery at a future date. Institutional
investors with which such contracts may  be made include commercial and  savings
banks, insurance companies, pension funds, investment companies, educational and
charitable  institutions and  others, but in  all cases such  purchasers must be
approved by  the  Company. The  obligations  of  any purchaser  under  any  such
contract  will not be subject to any  conditions except that (1) the purchase of
the Offered Securities shall not at the time of delivery be prohibited under the
laws of any  jurisdiction to which  such purchaser is  subject and which  govern
such  investment  and (2)  if  the Offered  Securities  are also  being  sold to
underwriters, the  Company shall  have  sold to  such underwriters  the  Offered
Securities  not subject to delayed delivery.  Underwriters and other agents will
not have any responsibility  in respect of the  validity or performance of  such
contracts.

    The  anticipated date of delivery of Offered Securities will be set forth in
the Prospectus Supplement relating to each offering.

                                 LEGAL OPINIONS

    The validity of the  Securities and the Guarantees  will be passed upon  for
the Company and the Guarantor by Robert H. Beber, General Counsel of the Company
and  the Guarantor,  and for  the underwriters, dealers  and agents,  if any, by
Shearman & Sterling, 599 Lexington Avenue,  New York, New York 10022. Mr.  Beber
is  also  an Executive  Vice  President of  the  Company and  the  Guarantor and
beneficially owns  certain  securities of  the  Guarantor. Shearman  &  Sterling
occasionally represents Grace in corporate transactions and antitrust matters.
