that may be issued under this Plan shall be One Hundred Fifty Thousand (150,000)
shares of Common Stock.

         (b) Authorized but unissued shares of Common Stock and issued shares of
Common Stock held by the Company or a Subsidiary, whether acquired specifically
for use under this Plan or otherwise, may be used for purposes of this Plan. In
addition, shares of outstanding Common Stock purchased by an agent independent

deemed issued under this Plan for purposes of paragraph (a) of this section 4.

         (c) If any shares of Common Stock issued pursuant to this Plan shall,
after issuance, be reacquired by the Company or a Subsidiary from the recipient
of such Common Stock, or from the estate of such recipient, for any reason, such

         5. Use of Common Stock Issued under this Plan. Shares of Common Stock
may be issued under this Plan in respect of Fees and Retainers on such terms as
may be fixed by the Board of Directors from time to time. All shares of Common
Stock issued pursuant to this Plan shall be valued at not less than 100% of the
Fair Market Value of



such shares on the effective date of issuance of such shares, regardless of when
such shares are actually issued.

         6. Payment and Deferral of Retainers and Fees.

         (a) Except as otherwise expressly set forth in this section 6, (i) a
portion of any Retainer or Fee shall be payable in shares of Common Stock, with
the balance being payable in cash, all in accordance with determinations made by
the Board of Directors from time to time, and (ii) all payments shall be made as
promptly as practicable following the conclusion of each Service Period.

         (b) Subject to and in conformity with such procedures as may be
approved by the Board of Directors from time to time, a Nonemployee Director may
elect to receive in shares of Common Stock all or any portion of any Retainer or
Fee that would otherwise be payable in cash.

         (c) Not later than the day immediately preceding the first day of any
Service Period, a Nonemployee Director may elect to defer all or any portion of
the Common Stock or the cash payable in respect of any Retainer or Fee, as the
case may be, for the next following Service Period. Such election shall be made
in writing and, once made, shall be irrevocable.

         (d) (i) Any portion of a Retainer or Fee payable in cash and as to
which a deferral election is made shall be payable to the Nonemployee Director
or his or her heirs or beneficiaries in a lump sum or in installments (as
specified by the Nonemployee Director in accordance with arrangements approved
by the Board of Directors) following a date specified by the Nonemployee
Director, which date shall in no event be earlier than such Nonemployee
Director's termination from service. An interest equivalent on any amount so
deferred shall be computed at such rate or rates as may be fixed by the Board of
Directors from time to time.

         (ii) Any portion of a Retainer or Fee payable in Common Stock and as to

Director's termination from service. The Common Stock shall be held in a trust
established by the Company. Dividends paid on such Common Stock will be
reinvested in Common Stock. The Nonemployee Director shall have the right to
vote the Common Stock held in such trust, if, as and to the extent specified in
the trust.

         (e) The terms of this Plan are intended to insure that the electing
Nonemployee Director is not subject to income tax on any cash or Common Stock
(including any cash or Common Stock that has been deferred) until such amounts
are paid to the Nonemployee Director.



         7. Adjustment Provisions.

         (a) In the event that any reclassification, split up or consolidation
of the Common Stock shall be effected, or the outstanding shares of Common Stock
are, in connection with a merger or consolidation of the Company or a sale by
the Company of all or a part of its assets, exchanged for a different number or
class of shares of stock or other securities or property of the Company or for
shares of the stock or other securities or property of any other corporation or
person, or a record date for determination of holders of Common Stock entitled
to receive a dividend payable in Common Stock shall occur, the number, class and
kind of shares that have not been issued pursuant to this Plan shall be
equitably adjusted.

         (b) In the event that any spin off or other distribution of assets of
the Company to its shareholders (including without limitation an extraordinary
dividend) shall occur, the number, class and kind of shares that have not been
issued pursuant to this Plan shall be equitably adjusted.

         8. Term. This Plan shall be deemed adopted and shall become effective
on the date on which the Common Stock is distributed to the holders of common
stock of W. R. Grace & Co., a Delaware corporation subsequently renamed "Sealed

tenth anniversary of such date.

         9. General Provisions.

shall confer upon any person any right to continue to serve as a Nonemployee
Director or to receive Retainers or Fees.

         (b) No shares of Common Stock shall be issued pursuant to this Plan
unless and until all legal requirements applicable to the issuance of such
shares have, in the opinion of counsel to the Company, been complied with. In
connection with any such issuance, the person or entity acquiring the shares
shall, if requested by the Company, give assurances, satisfactory to counsel to
the Company, in respect of such matters as the Company or a Subsidiary may deem
desirable to assure compliance with all applicable legal requirements.

         (c) No person, individually or as a member of a group, and no
beneficiary or other person claiming under or through him or her, shall have any
right, title or interest in or to any shares of Common Stock allocated or
reserved for the purposes of this Plan except as to such shares of Common Stock,
if any, as shall have been issued to him or her. No rights to receive shares of
Common Stock under this Plan shall be subject in any manner to alienation, sale,
transfer, assignment, pledge, encumbrance or charge, except by will or the laws
of descent and distribution. The only rights that may exist under this Plan
shall be limited to those of an unsecured creditor of the Company.



         (d) Nothing in this Plan is intended to be a substitute for, or shall
preclude or limit the establishment or continuation of, any other plan, practice
or arrangement for the payment of compensation or benefits to Nonemployee
Directors that the Company now has or may hereafter put into effect.

         10. Amendments and Termination.

         (a) This Plan may be terminated, suspended or amended at any time by
