         (i)      A "change in control" shall be deemed to occur:

                  (A)      when any "person" is or becomes a "beneficial owner"

                  (B)      upon the sale of all or substantially all of the

                           combination other than any merger or business
                           combination which would result in the voting
                           securities of the Company outstanding immediately

                           October 1, 2000 through June 30, 2001, and a fee at
                           the annual rate of $100,000 thereafter. Such fees
                           shall be payable in bi-weekly installments, except
                           that on the occurrence of a change of control, the
                           Company shall pay to Price in a lump sum, without
                           discount, the fees that would have been paid to him
                           thereafter through June 30, 2004 had the term of the
                           consultancy continued to that date. To the extent
                           permissible by law, there shall be no withholding
                           deductions. In the event of Price's death,
                           disability, or incapacity, such fees shall be paid to
                           Price or his personal representative, as the case may
                           be, for the duration of the above term.

                  (ii)     The Company shall during the term of the consultancy
                           afford to Price all employee benefits which were
                           afforded to him prior to the date hereof. Such
                           benefits shall in all events terminate if and when
                           Price obtains full time employment with a third
                           party.

                  (iii)    The Company hereby vests Price in all options the
                           Company has granted to him. Any option that would
                           have expired prior to June 30, 2004 is extended until
                           June 30, 2004. Notwithstanding any contrary provision
                           in the options, he or his personal representative may
                           exercise such options throughout the term of this
                           consultancy.

                  (iv)     The Company hereby forgives that portion of a $59,500
                           loan to Price which the Company has not forgiven
                           heretofore.

3.       No Other Compensation. Except as set forth in this Agreement and
except for (i) vacation pay earned but not taken and (b) expenses incurred as
requested by the Company or any of its subsidiaries, Price is entitled to no
compensation or benefits from the Company for any matter or thing, whether for
severance or otherwise.

                  (iv)     arrangements with, or other information relating to,
                           the Company's customers, suppliers, representatives
                           and other persons who have business relationships

                  which is known or available from any third party without
                  breach of any obligation to the Company, or which is or
                  becomes available to the public without breach by Price of any
                  obligation to the Company.

         (c)      Until June 30, 2004:

                  (i)      Price will not disclose any confidential information
                           to any person or entity, whether prepared by him or
                           others.

                  (ii)     Price will not directly or indirectly use any
                           confidential information other than as directed by
                           the Company.

         (d)      During the period beginning on the date hereof and ending on
                  the later of June 30, 2004 or the second anniversary of the
                  date of termination of the consultancy, Price will not
                  anywhere directly or indirectly (whether as an owner, partner,
                  employee, consultant, broker, contractor or otherwise, and
                  whether personally or through other persons, provided that
                  ownership of neither (i) shares of NutritionU nor (ii) less
                  than 3% of the stock of a company other than NutritionU does
                  not constitute "ownership" for the purposes of this Section):

                                       3
<PAGE>

                  engage in any aspect of the business of offering nutrition
                  education services over the Internet;

                  (i)      retain or employ any person or entity who on the date
                           of this Agreement is an employee of the Company or
                           any of its subsidiaries (except to the extent that
                           such person or entity is fired or laid off by the
                           Company at a subsequent time); or

                  (ii)     solicit or encourage any person to leave the employ
                           of the Company or any of its subsidiaries.

         (e)      Price understands that the provisions of this Section have
                  been carefully designed to restrict his activities to the
                  minimum extent which is consistent with the Company's
                  requirements. Price has carefully considered these
                  restrictions, and Price confirms that they will not unduly
                  restrict his ability to obtain a livelihood.

         (f)      Since monetary damages will be inadequate and the Company will
                  be irreparably damaged if the provisions of this Section are
                  not specifically enforced, the Company shall be entitled,
                  among other remedies to seek an injunction restraining any
                  violation of this Section (without any bond or other security
                  being required) by Price and by any person or entity to whom
                  Price provides or proposes to provide any services in
                  violation of this Section.

         (g)      If any provision contained in this Section is determined to be
                  void, illegal or unenforceable, in whole or in part, then the
                  other provisions contained herein shall remain in full force
                  and effect as if the provision which was determined to be
                  void, illegal, or unenforceable had not been contained herein.

         (h)      The courts enforcing this Section shall be entitled to modify
                  the duration and scope of any restriction contained herein to
                  the extent such restriction would otherwise be unenforceable,
                  and such restriction as modified shall be enforced.

5.       Return of Materials.

         (a)      Price will promptly on request deliver to the Company all
                  files, papers, recordings and other documents (whether in
                  note, memo or other document form or on video, audio or
                  computer tapes or discs or otherwise) that are then in his
                  possession, custody or control, whether prepared by him or
                  others, and which relate in any

                                       4

<PAGE>

                  way to the Company or any of its subsidiaries (except to the
                  extent that such files, papers, recordings and other documents
                  are necessary for Price to possess as a shareholder of
                  NutritionU).

         (b)      Price acknowledges that all files, papers, recordings and
                  other documents (whether in note, memo or other document form
                  or on video, audio or computer tapes or discs or otherwise)
                  that at any time come into Price's possession, custody or
                  control, whether prepared by him or others, and which relate
                  to the Company or any of its subsidiaries (except to the
                  extent that such files, papers, recordings and other documents
                  are necessary for Price to possess as a shareholder of
                  NutritionU), is and shall at all times be and remain, the
                  property of the Company.

6.       Cooperation in Proceedings; No Derogation.

         (a)      Price will for no compensation (other than the payment of his
                  out of pocket expenses) cooperate fully and at reasonable
                  times with the Company and its subsidiaries in all litigations
                  and regulatory proceedings on which the Company or any
                  subsidiary seeks his assistance and as to which he has any
                  knowledge or involvement. Without limiting the generality of
                  the foregoing, Price will make himself available to testify at
                  such litigations and other proceedings, and he will cooperate
                  with the Company's counsel in preparing materials and offering
                  advice in such litigations and other proceedings.

         (b)      Price will not from and after the date hereof, in any way or
                  to any person, denigrate or derogate the Company or any of its
                  subsidiaries, or any their officers, directors, products,
                  services or procedures, whether or not such denigrating or
                  derogatory statements shall be true and are based on acts or
                  omissions which are learned by Price from and after the date
                  hereof or on acts or omissions which occur from and after the
                  date hereof, or otherwise.

         (c)      The Company will not from and after the date hereof, in any
                  way or to any person, denigrate or derogate Price or any of
                  his services or procedures, whether or not such denigrating or
                  derogatory statements shall be true and are based on acts or
                  omissions which are learned by Company from and after the date
                  hereof or on acts or omissions which occur from and after the
                  date hereof, or otherwise.
