                                   AGREEMENT

variety of health and natural food products.  TOL owns federal trademark

          B.  As early as July 12, 1992, BEF adopted and is using the marks
"BALANCE" and "BALANCE, THE COMPLETE NUTRITIONAL FOOD" as a trademark in
connection with food bars.  BEF adopted and is using the mark "40-30-30 BALANCE"
in connection with food bars and powdered beverages.  BEF owns federal trademark
registration no. 1,956,964 for "BALANCE, THE COMPLETE NUTRITIONAL FOOD" and
pending application nos. 75/331,009, 75/321,186 and 75/321,184 for "BALANCE" and

          C.  Pursuant to an agreement dated as of December 19, 1996 between TOL
and BEF (the "Trademark Agreement"), the scope of BEF's use of the word
"BALANCE" was restricted to certain uses.

          D.  TOL and BEF desire to terminate the Trademark Agreement and enter
into a new agreement with respect to the use of the word "BALANCE(D)."

          NOW, THEREFORE, in consideration of these recitals and the following
mutual promises, the parties agree that the Trademark Agreement is hereby
amended and restated as follows:

1.  TOL AGREEMENTS.
    -------------- 

    1.1  TOL will not claim that the following actions taken or to be taken by
         BEF constitute infringement of the TOL Marks or otherwise constitute

         1.1.1 BEF's use of the marks "BALANCE, THE COMPLETE NUTRITIONAL FOOD",
               "40-30-30 BALANCE" and "BALANCE 40-30-30" in connection with any

        1.1.2  BEF's use of the word "BALANCE" alone or in conjunction with
               other word(s) and/or symbols in connection with: (a) any type of
               nutritional bar products, and (b) processed foods and meals but
               only if they are not in the same categories or types of products
               as those listed on Exhibit 1 attached hereto and any additional
               products introduced by TOL under the mark BALANCED or a BALANCED
               formative mark.

        1.1.3  BEF's use or seeking registration of marks containing the term
               Balance (and which do not begin with Balance and which do not
               begin with an article, pronoun, preposition, or other
               nonsubstantive term followed by the word Balance), including 40-
               30-30 Balance, for products falling in classes 5, 30 and 32 of

               replacements provided the mark: (a) does not begin with the word
               "BALANCE" or with an article, pronoun, preposition or other
               nonsubstantive term followed by the word "BALANCE", and (2) is
               not used with a tag line,

                    NUTRITIONAL DRINK" used by TOL for similar products.

          The marks described in Section 1.1 above are collectively defined as
          the "BEF Marks." TOL will refrain from taking any action or bringing
          any proceeding, legal or otherwise, against BEF's (or its successors,
          licensees and assigns and their respective affiliates and
          subsidiaries) use of the BEF Marks in connection with BEF's Products.
          In this regard, TOL will neither oppose any federal or state
          application to register nor seek cancellation of any federal or state
          trademark registration of the BEF Marks.

     1.2  TOL will not use the word "BALANCED" alone or in conjunction with
          other word(s) and/or symbol(s) on or in connection with the
          manufacturing, producing, distributing, marketing, advertising and
          otherwise exploiting of nutritional bar products.

     1.3  TOL will not use the word "BALANCE" alone or in conjunction with other
          word(s) and/or symbol(s) on or in connection with any goods or
          services; provided that such restriction will not apply to the use of
          the word "BALANCE" in a non-trademark or non-trade name manner.

     2.1  BEF will not claim that TOL's use of the TOL Marks in connection with
          the TOL Products constitutes an infringement of the BEF Marks, or
          otherwise constitutes unfair competition or a violation of any of
          BEF's rights, and will refrain from taking any action or bringing any
          proceeding, legal or otherwise, against TOL's (or its successors,
          licensees and assigns and their respective affiliates and
          subsidiaries) use of the TOL Marks in connection with the TOL
          Products. In this regard, BEF will neither oppose any federal or state
          application to register nor seek cancellation of any federal or state
          trademark or service mark registration of the TOL Marks in connection
          with TOL Products. It is understood and agreed that TOL Products will

          other word(s) and/or symbol(s) on or in connection with any goods or
          services; provided that such restriction will not apply to the use of
          the word "BALANCED" in a non-trademark or non-trade name manner.

     formative marks and names under this Agreement if such marks contain or are
     used with other marks, names, terms, designs that violate the proprietary
     rights of the other party (e.g.,
