As described in the prospectus on page 17, under Business: Future Growth
Strategy, "an important element of our future strategy is the successful
registration of our subsidiary, MCAP Investment Banking Services, as a
broker-dealer."  This supplement addresses that completed registration.

  Investment Banking Services

  On September 6, 2001, MentorCap established a wholly owned corporate
  subsidiary, MCAP Investment Banking Services, Inc., or MCAP.  This subsidiary
  was formed in expectation of obtaining a broker/dealer license through the SEC
  and membership in the NASD.

  The initial application for registration as a broker/dealer was filed with the
  NASD on or about October 8, 2001.  On March 14, 2002, the NASD approved the
  broker/dealer license for MCAP, enabling it to underwrite private placements
  and public offerings for its clients.  MCAP intends to specialize in smaller
  initial public offerings, generally ranging from $1 to $5 million dollars.
  MCAP intends to focus on funding companies that offer revolutionary and
  patented consumer products that we believe have mass appeal and sizeable
  national and international sales potential.

As described in the prospectus on page 17, under Business: Future Growth
Strategy, MentorCap, from time to time, may pursue "partnering or joint venture
agreements with companies whose products or services lend themselves to our
direct marketing strategies."  To date, MentorCap has reviewed more than 1,500
companies as potential partnering/joint venture candidates.  This supplement
supplies additional information related to such partnering or joint venture
agreements entered into by MentorCap.

  Product Development Agreement Signed with AgriHouse, Inc.

  Establishment of Wholly-owned Subsidiary, AeroGrow International, Inc.

  On June 25, 2002, MentorCap executed an exclusive agreement with AgriHouse,
  Inc., to develop, manufacture and market a low cost, consumer, aeroponic
  kitchen crop appliance (tm), the AeroGrow(tm) Kitchen Garden(tm).

<page>

  AgriHouse was founded by Richard Stoner, who in 1982 was the first person to
  develop, manufacture and market a commercial aeroponic growing unit in the
  United States.  MentorCap, building on Stoner's 20-year history and patented
  aeroponic technology, is developing the first consumer, aeroponic kitchen crop
  appliance.

  Aeroponics technology is featured in Disney World, Epcott Center's Future
  World in a 4-acre soil less garden exhibit called "The Land."

  Stoner's Aeroponics technology was also tested by NASA for its potential in
  "space farming."  When compared with the top two soil-less growing methods,
  Stoner's aeroponics unit grew 82% more biomass in the same period of time.

  MentorCap has formed a wholly owned subsidiary named AeroGrow International
  Inc., to design, manufacture and market this new product nationally and
  internationally.

  The terms of MentorCap's agreement with AgriHouse grant us the right to use
  AgriHouse's patent and all of the NASA research, data, and test results in the
  development and marketing of the AeroGrow Kitchen Garden.  In addition, the
  product development agreement grants MentorCap the exclusive worldwide direct
  marketing rights for the AeroGrow unit.

  As of the date of this supplement, the final research and development on the
  Kitchen Garden unit is in final prototype stage.  In addition, a website has
  been launched at http://www.aerogrow.com.  Mentor Cap has engaged the services
  of patent counsel and intends to file two utility patents and one design
  patent for the AeroGrow Kitchen Garden unit within 30 days from the date of
  this supplement. Upon review of accessible and relevant existing patent
  filings, counsel believes MentorCap's proposed Aeroponic growing apparatus
  utility patents do not infringe on existing patents, offer a novel apparatus
  and method for Aeroponic crop production, and are patentable based upon prior
  art.

  The proposed unit is intended to allow consumers to easily grow organic
  vegetables, herbs and flowers, indoors, year round.   We believe this unit has
  the potential to appeal to a variety of sizable markets such as:

  * The home gardening market of both experienced inexperienced gardeners --
    Potentially appealing to consumers that can't grow year round, especially
    those in geographically challenged areas with long winters and short growing
    seasons, as well as those city dwellers with limited land or living space
    such as condo or apartment residents.
  * The health conscious market of individuals who want to eat healthy and place
    value on home grown organic vegetables.
  * The gourmet cook and home chef market that may want countertop access to
    fresh cooking herbs and vegetables

<page>

  * The gift market --  The aeroponic Kitchen Garden may be an appealing gift
    for children, parents and spouses for Christmas, Mothers Day, birthdays,
    etc.

  We believe that there is a sizable worldwide market for a low cost, easy to
  use, attractive, aeroponic home unit designed as a kitchen appliance.

  On June 25th, 2002, an additional marketing agreement was entered into between
  MentorCap and AgriHouse for its ODC/Beyond liquid growth enhancer for plants,
  flowers and vegetables.  This agreement grants MentorCap the exclusive US
  direct marketing rights and the non-exclusive worldwide rights for the
  ODC/Beyond products.  This formula was tested by NASA on the Mir space station
  and was proven to significantly increase crop yields compared to plants grown
  without the formula.  The ODC formula is patented.

  Benefits claimed by the manufacturer include accelerated plant growth and
  strengthened plant immune system and stress tolerance.  This offers
  potentially improved plant growth in harsh environmental conditions such as
  drought, extreme temperature variations and infestation by harmful insects.
  Use of this product potentially reduces or eliminates the need for pesticides.

  We believe that there is a growing consumer awareness of the negative health
  and environmental consequences of pesticide use.  We also believe that the
  organic nature of the ODC formula, combined with its potential for accelerated
  plant growth, offers a large potential consumer and retail market for the
  ODC/Beyond product.

  Product Development Agreement: Voice Powered Technology, LLC.

  On July 19th, 2002, MentorCap entered into an exclusive product development
  agreement with Voice Powered Technologies, LLC.  Voice Powered Technologies
  has the worldwide manufacturing and marketing rights to a hand held, patented
  voice recognition technology for a product called the Voice Organizer IQ.

  This product development agreement grants MentorCap the right to use the
  existing patented voice recognition algorithms as a core engine for use in the
  development of a proposed, unique, hand held, voice powered
  scheduler/organizer that intends to utilize a new generation of voice
  recognition and voice to text technology.  The agreement grants MentorCap the
  exclusive worldwide direct marketing rights for the new, proposed voice
  organizer.

  The Intended Features and Functions of the Hand Held Voice Organizer:

    The proposed unit easily and automatically keeps users aware of their
    schedules, deadlines and appointments.  The user simply speaks a message
    with the time and date to be reminded and the "voice organizer" will play
    the message back on the exact time and day requested.

    We intend to design the unit to be compatible with the two primary, low
    cost, desktop based, voice recognition software packages on the market.
    This would potentially allow the user to dictate or record up to four hours
    in their hand held voice organizer and using a standard USB port connector,
    link to their computer where the voice to text software can transcribe the
    message into a standard Microsoft Word document.

    MentorCap intends for the proposed unit to interface with Microsoft's
    Outlook scheduling, calendar and task management system, allowing users to
    speak new appointments to the voice organizer and upload those appointments
    to their Outlook calendar.   It is intended that appointments in Outlook can
    also be downloaded from their computer to their voice organizers so the user
    can be verbally reminded of important appointments when out of the office or
    traveling.

  The original Voice Organizer IQ was developed by Voice Powered Technology,
  Inc., a California based corporation founded in 1989 by MentorCap's current
  CEO, Michael Bissonnette.

  We believe that there is a large and growing market for a simple, consumer
  friendly, voice controlled alternative to the palm sized organizers such as
  the Palm Pilot or the Pocket PC.
