                    Re:  Rules and Procedures for Submission of
                         Proposals to Acquire Grow Group, Inc.

          Gentlemen:

               The Board of Directors of Grow Group, Inc. (the
          "Company" or "Grow") has determined that under current
          circumstances it is in the best interests of the
          shareholders of the Company that there be instituted a
          formal bidding process for the Company.

               The Board of Directors of the Company (the "Board"
          or "Board of Directors") has further determined that this
          process must be conducted in a fair, impartial and
          orderly manner.  The interests of Grow's shareholders,
          employees, and other constituencies can and will be best
          served by such an approach.  The Board of Directors
          recognizes that the process in which the Company is
          currently engaged presents certain risks, particularly if
          the process is unduly prolonged, including disruption to
          the Company's business and overall uncertainty among the
          Company's constituencies as to the Company's future.  In
          order to mitigate these risks, the Board of Directors
          believes that the most prudent course of action is to
          bring this process to a prompt and orderly close.

               Accordingly, the Board of Directors has established
          the rules and procedures specified below to provide both
          Imperial Chemical Industries PLC ("ICI") and The Sherwin-
          Williams Company ("Sherwin-Williams") with the
          opportunity to submit improved acquisition proposals to
          acquire the Company ("Proposals").  The rules and
          procedures are designed to constitute a single and final
          round of bidding, and accordingly each of you should
          submit your best and highest offer.

               The purpose of this letter is to invite each of you
          to submit Proposals, pursuant to the rules and procedures
          set forth below.  The Board of Directors believes that
          agreement to such rules and procedures is in the best
          interests of the Company and its shareholders and,
          accordingly, submission of a Proposal will constitute for
          all purposes an agreement to be bound by such rules and
          procedures.  The Board of Directors reserves the right
          not to consider or recommend any Proposal made by a party
          who has not agreed to the rules and procedures specified
          below.

               The following rules and procedures will govern the
          submission of Proposals:

                    1.   Proposals should be addressed and
          delivered in a sealed envelope to the Board of Directors
          of the Company: c/o Daniel E. Stoller, Esq., Skadden,
          Arps, Slate, Meagher & Flom, 919 Third Avenue, 33rd
          Floor, New York, New York  10022.  Proposals must be
          received on Sunday, May 21, 1995 by no later than 12:00
          Noon, New York time (the "Submission Time"), unless
          extended by notice to each of you.

                    2.   Your Proposal must be stated as a single
          cash amount (expressed in U.S. dollars and cents) per
          share of Common Stock of the Company (the "Shares") and
          may not make reference to, be contingent upon, or in any
          way vary based upon, the terms (including the
          consideration offered) of the other party's Proposal.
          The submission of a Proposal will constitute your
          agreement to be bound by these rules and procedures and
          will also constitute your agreement that your Proposal is
          irrevocable until midnight on Tuesday, May 23, 1995.  You
          may not make any Proposal, or modify or amend any pending
          Proposal, to purchase the Company, except in accordance
          with these rules and procedures.

                    3.   Until the Company has accepted one of the
          Proposals, the Company will not, except as may be
          required by law, publicly disclose the terms of either of
          your Proposals or communicate them to the other of you.
          The Company reserves the right, however, to discuss any
          Proposal with the party submitting it.  Submission of
          your Proposal constitutes a representation that you have
          kept and will keep your Proposal confidential until 9:00
          a.m., New York time, on Monday, May 22, 1995 and that you
          have no knowledge of the other party's Proposal.  In
          addition, each of ICI and Sherwin-Williams agrees that
          they and their respective representatives will not
          directly or indirectly contact or communicate with the
          other or the other's representatives concerning their or
          the other party's Proposal or the submission of any
          Proposal.  By submitting a Proposal, ICI agrees to waive
          the Company's notice obligation contained in Section 6.04
          of the Agreement and Plan of Merger, dated as of April
          30, 1995, by and among the Company, ICI and GDEN
          Corporation (the "ICI Merger Agreement") with respect to
          any Proposal submitted by Sherwin-Williams.

                    4.   Not later than 10:00 a.m. on Thursday, May
          18, 1995, the Company will deliver to both of your
          respective counsels copies of (i) a form of amendment to
          the ICI Merger Agreement (the "ICI Form of Amendment")
          and (ii) a form of Agreement and Plan of Merger among
          Sherwin-Williams, GGI Acquisition, Inc., a wholly-owned
          subsidiary of Sherwin-Williams ("GGI"), and the Company,
          together with disclosure schedules (the "Sherwin-Williams
          Form of Merger Agreement").  ICI's Proposal shall be
          accompanied by an executed copy of the ICI Form of
          Amendment, executed by ICI and GDEN Corporation, an
          indirect wholly-owned subsidiary of ICI.  Sherwin-
          Williams' Proposal shall be accompanied by an executed
          copy of the Sherwin-Williams Form of Merger Agreement.
          The extent and nature of any changes proposed by ICI to
          the ICI Form of Amendment or proposed by Sherwin-Williams
          to the Sherwin-Williams Form of Merger Agreement will be
          taken into consideration by the Board of Directors.  If
          either party makes changes to the form of agreement
          furnished by the Company, the executed agreement shall be
          accomplished by a marked copy which shows any such
          changes.

                    5.   The Sherwin-Williams Form of Merger
          Agreement will contain a provision identical to the
          provisions of Section 11.04(b) of the ICI Merger
          Agreement.  Both the Sherwin-Williams Form of Merger
          Agreement and the ICI Form of Amendment will include a
          provision in the form of Appendix A hereto, which
          provides for the payment of an additional fee of $16
          million, under circumstances specified therein, if an
          Acquisition Transaction (as defined therein) has been
          consummated within six months of termination of the
          applicable merger agreement with ICI or Sherwin-Williams,
          as the case may be.

                    6.   It is the intention of the Board of
          Directors that the winning Proposal will be accepted as
          promptly as practicable after 12 Noon, New York time, on
          Sunday, May 21, 1995.  It is requested that each of you
          and your financial and legal advisors be available
          commencing at 12 Noon, New York time, on Sunday, May 21,
          1995 and continuing through 9:00 a.m., New York time, on
          Monday, May 22, 1995.

                    7.   As soon as practicable following the
          Submission Time, the Board of Directors, with the advice
          and assistance of its financial and legal advisors, will
          evaluate the Proposals.  The Board intends to accept the
          Proposal which it determines in its reasonable good faith
          judgment is the best value reasonably obtainable for the
          shareholders of the Company.  A Proposal will be accepted
          only by countersignature by the Company on the ICI Form
          of Amendment or the Sherwin-Williams Form of Merger
          Agreement, as the case may be.

                    8.   The party whose Proposal is not accepted
          agrees to immediately terminate its pending tender offer
          to acquire Shares and to not purchase or offer to
          purchase any Shares following the Submission Time.

                    9.   Representatives of the Company and its
          financial and legal advisors are prepared to meet with
          either of you or your respective legal and financial
          advisors to discuss these rules and procedures and to
          discuss the provisions of the ICI Form of Amendment and
          the Sherwin-Williams Form of Merger Agreement.

                    10.  The Board of Directors reserves the right,
          in its sole discretion, consistent with its fiduciary
          duties and without stating a reason therefor, to modify
          or terminate any or all of the rules and procedures set
          forth in this letter.  If the Board of Directors modifies
          these rules and procedures, it intends promptly to notify
          both of you orally, with subsequent confirmation in
          writing.

                                             Very truly yours,

                                             ON BEHALF OF THE
                                             BOARD OF DIRECTORS OF
                                             GROW GROUP, INC.
