      mold by the number of applications it was designed to perform and
      multiplying the quotient by the number of applications remaining to be
      made using such mold. The number of applications remaining to be made will
      be the number of applications the mold was designed to perform less the
      number of applications made to that date using that mold. The purchase
      price for the Molds, as will be agreed by the parties using the above
      described formula will be paid in twelve equal monthly installments
      commencing 15 days from final inspection and validation of the Molds by
      Milestone, to be performed no later than August 1, 2004. Upon payment of
      the first installment, the parties will execute a bill of sale reflecting
      the passage of ownership in the Molds to Milestone.

Apparatus for curing resin in dentistry

                                    ABSTRACT

A self contained light source for curing light initiated resins used to coat
teeth as veneers and fill cavities and chips in teeth in aesthetic or
restorative procedures. The source includes an elongated container holding a
battery and electronic compartment at one end and a light emitting window at the
other. A plurality of closely space light emitters, typically light emitting
diodes or laser diodes, are arrayed to direct light to a common focal point. The
light is directed out of the container toward a tooth bearing the resin to be
cured to a hard, stable state. The light emitters produce light in a region of
the spectrum to which the resin curing initiators is sensitive, typically blue
light. The light emitters are preferably mounted on concave edged printed
circuit so that they are all oriented inwardly toward the focal point.
Microlenses may be used with each light emitter to further concentrate light
toward the focal point. Preferably, a light transparent barrier sleeve is placed
over the light emitting end of the container and replaced between patients.

Mr. Alan A. Creamer
16065 Viadelas Palmas
Rancho Santa Fe, CA 92091


Dear Alan:

It is with great pleasure that I extend an offer to join the Milestone
Scientific team as Business Unit Manager, Diode Lighting Systems. In this new
capacity, you will be responsible for the growth of this extremely important
segment of our business. The opportunity is multi-functional, which will provide
an extremely dynamic opportunity. We are all very excited about you joining our
team. The specifics of the offer are attached.

The timing of the offer is contingent on our agreement regarding the purchase of
the usable inventory. I am planning on reviewing this with you and taking a
physical count the week of March 29th. Once Milestone owns the usable inventory,
we will begin purchasing the components necessary to build the CoolBlue Wand,
the "toothbrush" model as well as accessories. We must still agree on the final
cost of the units to Milestone following these transactions.

Alan, I realize that this is a big step for both or us; however, I am confident
that both you and Milestone will derive mutual benefit. If you are in agreement
with terms outlined on the attached offer, please sign in the appropriate
section and let's get going!



Sincerely,


/s/ Stuart J. Wildhorn

Stuart J. Wildhorn
President

MEMO


TO:       Kevin Lusardi

FROM:     Stu Wildhorn

CC:

DATE:    August 31, 2004

RE:      Da Vinci Mold Purchase

--------------------------------------------------------------------------------

Kevin, as part of the agreement with Da Vinci and Alan Creamer, Milestone agreed
to purchase the molds for the CoolBlue Wand handset, charger base and rubber
parts. The agreement stipulated that the purchase price would be based on
dividing the original price of each mold by the number of applications it was
designed to perform and multiplying the quotient by the number of applications
remaining to be made for each mold.

I have attached a letter from the mold firm, Enstrom Mold and Engineering, Inc.,
that states they will guarantee the molds for as long as Milestone uses them, at
no charge, as long as they remain in their facility. I have also personally
inspected the molds and found them to be in perfect working order.

Based on the above and pursuant to Section 4.2, Sale of Inventory and Molds
(attached for your reference), please set up to pay Da Vinci the sum of
$63,980.00 in twelve equal payments of $5,331.67, commencing September 1st. Per
the agreement, once Da Vinci receives the initial payment, we will execute a
bill of sales reflecting the passage of ownership in the molds to Milestone.

Please let me know if you need any additional information.

Thank you
