Grace & Co. (sometimes called the "Company"), at its meeting on April 1, 1998, granted you an award of .......... shares of the Company's Common Stock, par value $.01 per share ("Common Stock"), under the W. R.

The Restricted Shares are issued to you subject to the following restrictions: (a) As long as you are employed by the Company or a Subsidiary (as defined in paragraph 10 below), you will not, except as otherwise specifically required or permitted by this Agreement, sell, exchange, transfer, pledge, hypothecate or otherwise dispose of any of the Restricted Shares, or any interest therein, with respect to which the restrictions on transfer herein imposed have not lapsed in accordance with paragraph 5 ("Non-vested Shares"). (b) In any of the following events, you shall return all Non-vested Shares to the Company promptly upon the Company's written request: THIS DOCUMENT CONSTITUTES PART OF A PROSPECTUS COVERING SECURITIES THAT HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. - 2 - (i) You shall at any time have disclosed to unauthorized persons trade secrets, confidential information or data relative to the business of the Company or Subsidiary.

(iii) You shall at any time have engaged in misconduct (A) in the performance of your duties or (B) in other activities relating to the business of the Company or a Subsidiary. (iv) You shall at any time have attempted to sell, exchange, transfer, pledge, hypothecate or otherwise dispose of any Non-vested Shares, or any interest herein, in violation of the terms of this Agreement. (c) (i) The determination as to whether an event has occurred requiring the return of any Non-vested Shares to the Company in accordance with this paragraph 1 shall be made by the Committee in the reasonable exercise of its discretion, and such determination of the Committee with respect thereto shall in all respects be conclusive. (ii) If you shall at any time be required to return any Non-vested Shares to the Company pursuant to this paragraph 1 or any other provision of this Agreement, you shall, from and after the effective date of such return, no longer have any rights as a stockholder with respect to the Non-vested Shares so required to be returned, or any interest therein, and, without limitation, you shall, commencing with the next following record date, no longer be entitled to receive dividends upon such Non-vested Shares and in the event that for any reason you shall have received such dividends upon such Non-vested Shares, you shall repay an amount equal to such dividends to the Company. - 3 - (d) To evidence such restrictions, until such restrictions shall have lapsed, the certificates for the Restricted Shares shall bear a legend, in form and substance satisfactory to the Company's counsel, to the effect that they were issued subject to, and may be sold or otherwise disposed of only in accordance with, the terms of this Agreement. 2. Upon the issuance to you of the Restricted Shares, you shall for all purposes be a stockholder of the Company with respect to the Restricted Shares and shall have all rights of a holder of Common Stock with respect to such shares (including the right to vote such shares at any meeting of holders of Common Stock and the right to receive all dividends, if any, paid with respect to such shares), subject only to the restrictions imposed by paragraph 1 of this Agreement. 3. Under Section 83(b) of the Internal Revenue Code, you may, within 30 days following the date of grant of the Restricted Shares, make an election that would cause you to be taxed on an amount equal to the Fair Market Value (as defined in the Plan) of such shares on the date of grant. In the absence of such an election, you will be taxed, at the time or times of the lapse of the restrictions on the Restricted Shares, on an amount equal to the Fair Market Value at the time of the lapse of the Restricted Shares as to which the restrictions have lapsed. 4. In the event that, as the result of a stock dividend, stock split, recapitalization, merger, consolidation, reorganization, or other similar event, you shall, as the owner of Restricted Shares, be entitled, under the provisions of Section 8 of the Plan or otherwise, to new or additional or different shares or securities, (a) such new or additional or different shares or securities shall be deemed "Restricted Shares," (b) all the provisions of this Agreement relating to restrictions and lapse of restrictions shall be applicable thereto, and (c) the certificates or other instruments evidencing such new or additional or different shares or securities shall bear the legend referred to in - 4 - paragraph 1(d).

(b) If your employment with the Company or a Subsidiary shall, while you hold any Non-vested Shares, terminate for any reason other than death, total disability, retirement at age 65 or later, or termination by the Company or a Subsidiary not for cause (including termination not for cause following a change in control of the Company), such Non-vested Shares shall be forfeited by you. If your employment with the Company or a Subsidiary shall, while you hold any Non-vested Shares, terminate by reason of death, total disability, retirement at age 65 or later, or termination by the Company or a Subsidiary not for cause (including termination not for cause following a change in control of the Company), the restrictions on transfer applicable to such Non-vested Shares shall lapse in their entirety as of the date of such termination of employment. If your employment with the Company or a subsidiary shall, while you hold any Non-vested Shares, terminate by reason of voluntary retirement under a retirement plan of the Company or a Subsidiary prior to age 65 with the consent of the Committee, the restrictions on transfer applicable to such Non-vested Shares shall lapse pro rata. (c) If, as and when the restrictions lapse with respect to any Restricted Shares pursuant to this paragraph 5, there will be delivered to you, promptly upon your request, one or more certificates free of any legend for a like number of shares in exchange for the certificate or certificates for such Restricted Shares bearing the legend referred to in paragraph 2 of this Agreement, subject to your payment of any tax required to be withheld in connection with such lapse. - 5 - 6.
