               among CONOPCO, INC., a New York corporation ("Parent"),
               CONOPCO ACQUISITION COMPANY, INC., a Delaware corporation
               and a wholly owned subsidiary of Parent ("Sub"), and the
               individual and partnerships listed on Schedule A hereto
               (each a "Stockholder" and, collectively, the
               "Stockholders").


          WHEREAS, Parent, Sub and Helene Curtis Industries, Inc., a
Delaware corporation (the "Company"), propose to enter into an Agreement
and Plan of Merger of even date herewith (as the same may be amended or
supplemented, the "Merger Agreement") providing for the making of a cash
tender offer (as such offer may be amended from time to time, the "Offer")
by Sub for any and all shares of Common Stock, par value $.50 per share, of
the Company (the "Common Stock") and the merger of the Company and Sub (the
"Merger"); and 

          WHEREAS, each Stockholder owns the number of shares of Class B
Common Stock, par value $.50 per share, of the Company (the "Class B Common
Stock") set forth opposite his or its name on Schedule A hereto; such
shares of Class B Common Stock, as such shares may be adjusted by
conversion into shares of Common Stock or by any stock dividend, stock

          WHEREAS, as a condition to their willingness to enter into the
Merger Agreement, Parent and Sub have requested that the Stockholders enter

          NOW, THEREFORE, to induce Parent and Sub to enter into, and in
consideration of their entering into, the Merger Agreement, and in
consideration of the premises and 







the representations, warranties and agreements contained herein, the
parties agree as follows:

          1.   Purchase of Subject Shares.
               ---------------------------

          (a)  Each Stockholder hereby grants Sub an irrevocable option
     (the "Option") to purchase all of the Subject Shares owned by him or
     it for a purchase price per share equal to $70.00 (as such amount may
     be adjusted to appropriately reflect any Adjustment Events, the
     "Original Offer Price").  The Option may be exercised in whole (but
     not in part) at any time after the date hereof and on or prior to the
     first anniversary of the date hereof (such first anniversary, the
     "Option Expiration Date") in the event that (i) a Specified Event (as
     defined in Section 1(b) below) shall have occurred on or prior to the
     Option Expiration Date and (ii) the waiting period under the
     Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act")
     with respect to the exercise of the Option shall have expired or been
     terminated.

          (b)  The term "Specified Event" shall mean (i) Parent or Sub
     shall have terminated the Merger Agreement under Section 9.01(d)
     thereof, (ii) the Company shall have terminated the Merger Agreement
     under Section 9.01(e) thereof, (iii) prior to termination of the
     Merger Agreement (other than by the Company pursuant to
     Section 9.01(f) or 9.01(g)), a Takeover Proposal (as defined in the
     Merger Agreement) shall have been commenced or the Company shall have
     entered into an agreement with respect to, approved or recommended or
     taken any action to facilitate, a Takeover Proposal or (iv) Sub shall
     have accepted for payment, and paid for, shares of Common Stock in the
     Offer.

          (c)  In the event that Sub wishes to exercise the Option, Sub may do
     so by giving written notice (the date of such notice being herein called 
     the "Notice Date") to each of the Stockholders specifying that all the
     Subject Shares are to be purchased and specifying the place, time and
     date (not earlier than two trading days, nor later than 10 trading days, 
     from the Notice





     Date) for the closing of the purchase by Sub pursuant to such
     exercise.  In the event that any share of Common Stock is accepted for
     payment, and paid for, by Sub pursuant to the Offer, Sub shall be
     obligated to exercise the Option no later than two trading days
     following the date of such payment and close the purchase of and pay
     for such Subject Shares within two trading days following the date of
     such exercise.  A "trading day" shall mean any date on which the New
     York Stock Exchange shall be open for business.

          2.   Payments to Parent or Stockholders.
               -----------------------------------

          (a)  In the event that a Specified Event shall have occurred and
     during the period from the first anniversary of the date hereof to and
     including the second anniversary of the date hereof, the Stockholder
     sells, transfers, assigns or otherwise disposes of (including by
     conversion or exchange in a merger, exchange offer or the like) any of
     the Subject Shares for value in a bona fide arm's length transaction,
     the Stockholder shall pay to Parent an amount in cash equal to the
     product of (i) the number of Subject Shares disposed of by the
     Stockholder and (ii) 50% of the excess, if any, of (A) the per share
     cash consideration or the per share fair market value of any non-cash
     consideration, as the case may be, received by the Stockholder as a
     result of such disposition less (B) the Original Offer Price;
     provided, however, that no such payment shall be required to be made
     --------  -------
     in the event the Company shall have terminated the Merger Agreement
     pursuant to Section 9.01(f) or 9.01(g) thereof or Parent or Sub shall
     be in material breach of this Agreement (and such breach shall not
     have been cured within 10 days following receipt by Parent or Sub of
     written notice of such breach).  

          (b)  In the event that Sub shall have exercised the Option
     pursuant to Section 1 with respect to the Subject Shares and, on or
     prior to the second anniversary of the date hereof, Sub shall sell,
     transfer, assign or otherwise dispose of (including by conversion or
     exchange in a merger, exchange offer or the like) any of such Subject
     Shares for value in a 







     bona fide arm's length transaction, Sub shall pay to the Stockholder
     an amount in cash equal to the product of (i) the number of such
     Subject Shares disposed of by Sub and (ii) 50% of the excess, if any,
     of (A) the per share cash consideration or the per share fair market
     value of any non-cash consideration, as the case may be, received by
     Sub as a result of such disposition less (B) the Original Offer Price;
     provided, however, that no such payment shall be required to be made
     --------  -------
     to any Stockholder in the event such Stockholder shall be in material
     breach of this Agreement (and such breach shall not have been cured
     within 10 days following receipt by such Stockholder of written notice
     of such breach).

          (c)  For purposes of Section 2 of this Agreement, the fair market
     value of any non-cash consideration consisting of:

               (i)  securities listed on a national securities exchange or
                    traded on the NASDAQ/NMS shall be equal to the average
                    closing price per share of such security as reported on
                    such exchange or NASDAQ/NMS for the five trading days
                    after the date of disposition; and

               
              (ii)  consideration which is other than cash or securities of
                    the form specified in clause (i) of this Section 2(c)
                    shall be determined by a nationally recognized
                    independent investment banking firm mutually agreed
                    upon by the parties within 10 business days of the
                    selection of such banking firm; provided, however, that
                                                    --------  -------
                    if the parties are unable to agree within two business
                    days after the date of disposition as to the investment
                    banking firm, then the parties shall draw lots to
                    select the investment banking firm from among the
                    following three firms:  Goldman Sachs & Co., CS First
                    Boston Corporation and Salomon Brothers Inc; provided
                                                                 --------
                    further, that the 
                    -------







                    fees and expenses of such investment banking firm shall
                    be borne equally by Parent and the Stockholder.  The
                    determination of the investment banking firm shall be
                    binding upon the parties.

          (d)  Any payment required to be made pursuant to Section 2 of
     this Agreement shall be made two trading days after the later of
     (i) the fifth trading day after settlement of any disposition or
     (ii) the date on which the investment banking firm delivers to the
     parties its determination of the per share value of any non-cash
     consideration received by the Stockholder or Sub, as the case may be,
     pursuant to any disposition.  In the event that Sub or any Stockholder
     shall sell, transfer, assign or otherwise dispose of any Subject
     Shares, other than for value in a bona fide arm's length transaction,
     the obligation of Sub or such Stockholder, as the case may be, to make
     payments pursuant to this Section 2 shall continue until and apply to
     any subsequent disposition of such Subject Shares in a bona fide arm's
     length transaction for value.

          (c)  The Stockholder agrees not to (i) other than by operation of
