<PAGE>

                           NONCOMPETITION AGREEMENT

     THIS NONCOMPETITION AGREEMENT (this "Agreement") is made as of the 15/th/
                                          ---------
day of March, 2000 by and between HealthCentral.com, a Delaware corporation
("HCC") and Robert M. Haft ("Key Employee").
  ---                        ------------

                                  BACKGROUND
                                  ----------

     This Agreement is entered into in connection with and is ancillary to an
Agreement and Plan of Reorganization and Merger (the "Plan"), dated as of March
                                                      ----
15, 2000 among HCC, HCC Acquisition Corp., a Delaware corporation and wholly
owned subsidiary of HCC ("Acquisition Corp"), and Vitamins.com, Inc., a Delaware
                          ----------------
corporation (the "Company"), pursuant to which Acquisition Corp is to merge with
                  -------
and into Company (the "Merger") and Company will continue as the surviving
                       ------
corporation in the Merger, and the shares of Company capital stock outstanding
immediately prior to the effective time of the Merger will be converted into
shares of HCC Common Stock.

     Key Employee is a stockholder of Company and has been actively involved in
the development and/or marketing of the Company's products and services. HCC
intends to continue the business of Company after the Merger and integrate such
business into HCC's ongoing business as a subsidiary of HCC. To preserve and
protect the assets of Company and HCC, including HCC's goodwill, customers and
trade secrets of which Key Employee has and will have knowledge in his or her
role as an employee, and in consideration for HCC's entering into and performing
under the Employment Agreement with Key Employee of even date herewith, Key
Employee has agreed to enter into this Agreement.

     Key Employee and HCC believe the limitations as to time, geographical area
and scope of activity contained in this Agreement hereof are reasonably
necessary to, and no greater than that required to, protect the goodwill and
business interests of HCC.

          1.   For the period beginning on the date on which Key Employee no
longer is an employee of or consultant to HCC (the "Effective Date") and ending
                                                    --------------
on the one-year anniversary of the Effective Date, Key Employee will not, in the
geographical areas referred to in Section 2 below, individually or as an
employee, consultant, partner, officer, director or shareholder or in any other
capacity whatsoever of or for any person, firm, partnership, or corporation
other than HCC or its subsidiaries, work as an employee or consultant, or own,
manage, operate, sell, control or participate in the ownership, management,
operation, sales or control of, any business engaged in the following (the
following being hereinafter referred to as the "Restricted Business"): (i) a
                                                -------------------
pharmacy or retail drugstore business (including but not limited to a business
involved in the provision of prescription, over-the-counter and health and
beauty products) that operates interactively via electronic media, including
over the Internet, or (ii) a business that provides health information, products
and services to the general public (including linkages between consumers and
health providers, payors and ancillary entities) in various communications
media, including but not limited to radio, television, internet, interactive
television, interactive cable and satellite; provided, however, that the
foregoing shall not prohibit
<PAGE>

Key Employee from providing services to (a) a business or a division of a
business that is not engaged in the activities described in (i) and (ii) above
(a "Permitted Business Unit") even though another division or affiliate of the
    -----------------------
business is engaged in such activities, provided that Key Employee's duties and
responsibilities exclusively relate to the Permitted Business Unit or (b) a
business engaged in the activities described in (i) and (ii) above, so long as
Key Employee is not directly engaged in or responsible for activities that would
constitute a Restricted Business, or (c) a primarily "bricks and mortar"
business which derives less than 15% of its revenue from the activities
described in (i) and (ii) above ((a), (b) and (c) being collectively referred to
as "Permitted Businesses"). Notwithstanding the foregoing or anything to the
    --------------------
contrary contained in this Agreement, (a) Key Employee may make personal
investments in nonpublicly traded corporations, partnerships or other entities,
which are not engaged in the Restricted Business, unless they are Permitted
Businesses, and (b) Key Employee may make personal investments in publicly
traded corporations regardless of the business they are engaged in, provided
that Employee does not at any time own in excess of 1% of the issued and
outstanding stock of any such publicly traded corporation that is engaged in the
Restricted Business, unless they are Permitted Businesses. For purposes of
illustrating the foregoing, Key Employee would not be precluded from employment
with Amazon.com so long as Key Employee was not directly engaged in or
responsible for any business of Amazon.com that is a Restricted Business. Key
Employee also would not be precluded from employment with Target Stores so long
as Target Stores does not derive more than 15% of its revenues from Restricted
Businesses.

          2.   The geographical areas in which the restrictions provided for in
this Agreement apply include all cities, counties and states of the United
States, and all other countries in which HCC or Company has engaged in sales or
otherwise conducted business or selling or licensing efforts in any aspect of
the Restricted Business at any time prior hereto or during the term of this
Agreement.  Key Employee acknowledges that the scope and period of restrictions
and the geographical area to which the restrictions imposed in this Section 2
applies are fair and reasonable and are reasonably required for the protection
of HCC and that this Agreement accurately describes the business to which the
restrictions are intended to apply.

          3.   Key Employee acknowledges that any breach of the covenants of
this Agreement will result in immediate and irreparable injury to HCC and,
accordingly, consents to the application of injunctive relief and such other
equitable remedies for the benefit of HCC as may be appropriate in the event
such a breach occurs or is threatened. The foregoing remedies will be in
addition to all other legal remedies to which HCC may be entitled hereunder,
including, without limitation, monetary damages.

Brand Optical now desires to assign the Agreements, and its rights and
obligations thereunder to HealthCentral.com; HealthCentral.com intends to assume
the Agreements and all rights and obligations of Brand Optical thereunder, and

     2.   Assumption of Liabilities by HealthCentral.com.  HealthCentral.com
          ----------------------------------------------
hereby assumes the Agreements and agrees to perform, pay and discharge in a
timely manner all obligations and liabilities of Brand Optical under such
Agreement which accrue on or after the Effective Date hereof.

     3.   Amendment.
          ---------

          Royalty Payments.  Edell and HealthCentral.com agree that any
          -----------------
obligation on HealthCentral.com (or Brand Optical) to pay a royalty to Edell as
provided for in Sections 5, 9, and 10 of each of the Agreements shall cease as
of January 1, 2000.  Edell acknowledges and agrees that Brand Optical shall be
solely responsible for payment of any and all royalties owing Edell as of the
Effective Date hereof.

<PAGE>

        4.      Payment to Edell.
                -----------------

        HealthCentral.com hereby agrees to make to Edell a one-time payment of
$1,500,000 within three business days after the latest of (i) the date on which
all relevant parties have executed and delivered this Assignment; and (ii) the
date on which all relevant parties have executed and delivered a separate
Amendment and Termination Agreement by and between Brand Optical, Edell and
HealthCentral.com (the "Termination Agreement").

        5.      Representations and Warranties.  Edell represents and warrants
                -------------------------------
that he owns all right, title and interest into the trademark and trade name
"Dr. Dean Edell" and has not granted any rights to any third person or entity

represents that the rights granted to HealthCentral.com in the Agreement are all
of Edell's rights which are necessary for HealthCentral.com to manufacture,
market and sell eyewear utilizing the Dr. Dean Edell Name and/or likeness.

        6.      Miscellaneous.  All other terms and provisions of the Agreement
                --------------
shall remain in full force and effect.  This Assignment may be executed
simultaneously in any number of counterparts, each of which shall be deemed an
original, but all of which taken together shall constitute one and the same
instrument.

                This assignment has been executed by the parties as of the date
first above written.
