                    SETTLEMENT AGREEMENT AND GENERAL RELEASE

      This Settlement Agreement and General Release ("Agreement") is made and
entered into by and among Bridgetech Holdings International, Inc. and all
affiliates of Bridgetech ("Bridgetech") on the one hand and Scott D. Landow,
(herein referred to as the "Employee") on the other (collectively Employee and
Bridgetech shall be referred to herein as the "Parties"). The effective date of
this Agreement shall be May 1, 2005.

                              W I T N E S S E T H:

      WHEREAS, Employee and Bridgetech entered into a employment agreement (the
"Employment Agreement") beginning in December of 2004; and

      WHEREAS, Employee and Bridgetech entered into a 39 Month Consulting
Agreement on May 1, 2005 (the "39 Month Agreement"); and

      WHEREAS, the Parties intend to terminate the respective rights and
obligations of the Parties pursuant to the Employment Agreement and the 39 Month
Agreement; and

      WHEREAS, all the Parties to this Agreement wish to avoid the disruption
and expense of litigation;

      NOW, THEREFORE, in consideration of the premises and mutual promises
contained herein, it is agreed as follows:

      1. This Agreement is not and shall not in any way be construed as an
admission by any party to this Agreement of any wrongdoing. The Parties have
entered into this Agreement for the sole purpose of resolving any matters
regarding the aforementioned Employment Agreement, the 39 Month Agreement and
any related disputes and to avoid the burden, expense, delay, and uncertainty of
litigation.

      2. As consideration for the release of any claims which were or could have
been made by any of the Parties under the Employment Agreement and the 39 Month
Agreement, the Parties agree to provide the following:

            (a) Bridgetech shall be obligated to pay Employee, as a consultant
to Bridgetech, $15,000 per month for a period of eighteen months beginning May
1, 2005. See the "18 Month Consulting Agreement," attached hereto as Exhibit A
and incorporated herein by reference as though set forth in full.

            (b) Employee agrees and acknowledges that all stock options/warrants
issued to Employee are hereby cancelled and are null and void. The foregoing
acknowledgement and relinquishment of Employee's rights to any stock options or
warrants held by Employee does not in any way affect or impact Employee's
ownership of any Bridgetech stocks/shares issued to or

acquired by Employee prior to the date of this Agreement. Employee further
agrees to void the 39 Month Agreement and replace it with the 18 Month
Consulting Agreement beginning May 1, 2005. Employee further agrees to resign
from the Bridgetech Board of Directors effective immediately. Employee agrees
that Bridgetech shall have the exclusive right and interest in all materials,
lists, databases, and other work produced or contributed by Employee pursuant to
the Employment Agreement ("Work Product"), and that Employee shall retain no
right or royalty interest in any such Work Product. (For purpose of this
Agreement, Work Product will be deemed to be any materials, lists databases and
other work produced exclusively for the benefit of the core businesses of
Bridgetech Holdings International and its subsidiaries, but does not under any
circumstances include any work in the Nutraceutical or Cosmeceutical Supplements
business.) If any of the Work Product by Employee under the Employment Agreement
shall be deemed at law to be within the categories of works set forth in the
definition of a "work made for hire," Employee agrees that it shall be
considered a work made for hire. If not deemed to be "work made for hire," then
Employee hereby assigns to Bridgetech any and all copyright or other interest in
such Work Product.

            (c) Employee shall keep all confidential and proprietary information
received during the term of the Employment Agreement in confidence and shall not
disclose to any other person or entity without prior written approval of
Bridgetech, any such confidential and proprietary information. The obligations
of the Employee to maintain confidential and proprietary information in
confidence shall be considered satisfied if the Employee takes all reasonable
steps to protect such confidential and proprietary information, according to the
protection measures and levels that would be considered reasonable at the
specific period concerned.

            (d) Employee agrees and acknowledges that all times Employee shall
not make any disparaging written, verbal or non-verbal remarks regarding
Bridgetech, its affiliates, officers, directors, employees, agents or
representatives. Bridgetech agrees and acknowledges that all times Bridgetech
shall not make any disparaging written, verbal or non-verbal remarks regarding
the Employee. The foregoing notwithstanding, this Agreement shall not prevent
the Parties from responding accurately to inquiries from government agencies or
regulators or to any requests for information compelled by legal process.

GENERAL RELEASE

      3. In consideration of the payments and undertakings described above and
in further consideration which is hereby acknowledged, the Parties to this
Agreement hereby release and forever discharge each other, their predecessors,

all claims and causes of action whatsoever, known or unknown, foreseen or
unforeseen, which any party has or may have by reason of any matter, cause or
thing whatsoever, from the beginning of the world to the day of this Agreement.
This Release includes but is not limited to any and all claims that could have
been asserted pursuant to the terms and conditions of the Employment Agreement

        THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN
