Michael Ackerman
Ionic White, Inc.
36 West 44th Street, 11th Floor
New York, NY 10036-8102,

Dear Mike:

     This will confirm our understanding with respect to the issuance of
incentive rewards to Ionic White, Inc., in the form of stock options and the
acquisition of our Common Stock.

     1.  On the execution hereof we shall grant to you 3-year options to
purchase 100,000 shares of Common Stock at an exercise price of $4.89 per share.
The options shall only become exercisable if during the one-year period
commencing July 1, 2005 you purchase Ionic White starter kits in the following
amounts:

         2,000,000 starter kits -  option exercisable for 10,000 shares

         2,500,000 starter kits -   options exercisable for 50,000 shares in the
         aggregate

         3,000,000 starter kits -  options exercisable for the full 100,000
         shares

     2.  In addition, you hereby agree to purchase at $3.00 per share and we
agree to issue and sell to you at that price, 500,000 shares of Common Stock. Of
these 500,000 shares, 125,000 shares shall be purchased within 10 days after the
end of each fiscal quarter commencing July 1, 2005, provided, however that we
shall have no obligation to sell such shares to you unless you have purchased
625,000 starter kits during the first quarter, an aggregate of 1,250,000 kits in
the first two quarters and an aggregate of 1,875,000 kits in the first three
quarters and provided, further, that at our option to be exercised by our
current Chief Executive Officer or his successor, all shares previously
purchased shall be returned to us and all monies paid refunded to you, if you
have not purchased at least 3,000,000 starter kits for the 12-month period
commencing July 1, 2005. We agree that any shares which you acquire under this
paragraph, including shares which may be returned to us, which are not saleable
in their entirety under an exemption from registration under the Securities Act
shall be included in any registration statement filed by us on Form S-3 during
the term hereof or thereafter so long as you hold any such shares. You may
assign these shares to your principals, Michael Ackerman and Eddie Mishan,
provided that they are then accredited investors as defined in Regulation D
under the Securities Act.

     3.  In addition, you hereby agree to include in each 28.5 minute
advertising segments that you buy on television for airing your informercials
for covering the Ionic White starter kits sixty to eighty seconds of additional
promotional material selected by us and covering our other products. We will pay
you for this advertising time on a prorata basis based on your out of pocket
costs for the advertising segments for Ionic White in which our material
appears. You shall provide us with a schedule showing the calculation of your
out-of-pocket advertising expense and our prorata share thereof certified by
your Chief Financial Officer or other officer reasonably acceptable to us. We
shall have the right to audit the information, underlying this schedule,
including your books and records, by an independent accountant of our choosing,
but no more frequently than once each month. Any such audit shall be conducted
during normal business hours or other hours acceptable to you. If the audit
determines that your calculations are correct the cost of such audit shall be
borne by us. If the calculation is not correct, the cost of such audit shall be
borne by you. Our obligation shall be payable through issuance of our Common
Stock valued at the closing price thereof on the day preceding the date of
issuance. We agree that any shares which you acquire under this paragraph, which
are not saleable in their entirety under an exemption from registration under
the Securities Act shall be included in any registration statement filed by us
on Form S-3 during the term hereof or thereafter so long as you hold any such
shares. You may assign these shares to your principals, Michael Ackerman and
Eddie Mishan, provided that they are then accredited investors as defined in
Regulation D under the Securities Act.

     4.  The shares to be acquired hereunder are being acquired by you for
investment and without a view to distribution and may not be sold in the absence
of registration under the Securities Act of 1933, as amended, or an exemption
therefrom. The shares shall bear an appropriate investment legend. Further you
represent that you are an accredited investor as defined in Regulation D under
the Securities Act.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first written above.

                            MILESTONE SCIENTIFIC INC.

                             STOCK OPTION AGREEMENT

                                                             Dated: May 18, 2005

     Milestone Scientific Inc. a Delaware corporation (the "COMPANY"), grants to
Ionic White, Inc. (the "OPTIONEE"), a stock option to purchase a total of
100,000 shares of the Company's Common Stock, par value $.001 per share, at
$4.89 per share on the terms and conditions set forth herein.

     1.   DURATION.

          This option shall expire three years from the date hereof (the
"TERMINATION DATE").

     2.   CHARACTERIZATION OF OPTIONS.

          Intentionally omitted.

     3.   ANTI-DILUTION PROVISIONS.

          (a) If there is any stock dividend, stock split, or combination of
shares of Common Stock of the Company, the number and amount of shares then
subject to this option shall be proportionately and appropriately adjusted; no
change shall be made in the aggregate purchase price to be paid for all shares
subject to this option, but the aggregate purchase price shall be allocated
among all shares subject to this option after giving effect to the adjustment.

          (b) If there is any other change in the Common Stock of the Company,
including recapitalization, reorganization, sale or exchange of assets, exchange
of shares, offering of subscription rights, or a merger or consolidation in
which the Company is the surviving corporation, an adjustment, if any, shall be
made in the shares then subject to this option as the Board of Directors may
deem equitable. Failure of the Board of Directors to provide for an adjustment
pursuant to this subparagraph prior to the effective date of any Company action
referred to herein shall be conclusive evidence that no adjustment is required
in consequence of such action.

          (c) If the Company is merged into or consolidated with any other
corporation, or if it sells all or substantially all of its assets to any other
corporation, then either (i) the Company shall cause provisions to be made for
the continuance of this option after such event, or for the substitution for
this option of an option covering the number and class of securities which the
Optionee would have been entitled to receive in such merger or consolidation by
virtue of such sale if the Optionee had been the holder of record of a number of
shares of Common Stock of the Company equal to the number of shares covered by
the unexercised portion of this option, or (ii) the Company shall give to the
Optionee written notice of its election not to cause such provision to be made
and this option shall become exercisable in full (or, at the election of the
Optionee, in part) at any time during a period of 20 days, to be designated by
the Company, ending not more than 10 days prior to the effective date of the
merger, consolidation or sale, in which case this option shall not be
exercisable to any extent after the expiration of such 20-day period. In no
event, however, shall this option be exercisable after the Termination Date.

     4.   INVESTMENT REPRESENTATION; LEGEND ON CERTIFICATES; SPECIAL RESTRICTION
          ON RESALE.

          The Optionee agrees that until such time as a registration statement
under the Securities Act of 1933 becomes effective with respect to the option
and/or the stock, the Optionee is taking this option and will take the stock
underlying this option, for his own account, for investment and not with a view
to the resale or distribution thereof. The Company shall have the right to place
upon the face of any stock certificate or certificates evidencing shares
issuable upon the exercise of this option such legend as the Board of Directors
may prescribe for the purpose of preventing disposition of such shares in
violation of the Securities Act of 1933, as now or hereafter provided.

     5.   NON-TRANSFERABILITY.

          This option shall not be transferable by the Optionee.

                                       2

     6.   CERTAIN RIGHTS NOT CONFERRED BY OPTION.

          The Optionee shall not, by virtue of holding this option, be entitled
to any rights of a stockholder in the Company.

     7.   EXPENSES.

          The Company shall pay all original issue and transfer taxes with
respect to the issuance and transfer of shares of Common Stock of the Company
pursuant hereto and all other fees and expenses necessarily incurred by the
Company in connection therewith.

     8.   EXERCISE OF OPTIONS.

          (a) This option shall become exercisable in accordance with its terms,
as follows:

          10,000    shares commencing on the date of grant provided that the
                    optionee has purchased at least 2 million starter kits for
                    the Company's consumer tooth whitening system before June
                    30, 2006;

          40,000    additional shares commencing on the date of grant provided
                    that the optionee has purchased at least 2.5 million starter
                    kits for the Company's consumer tooth whitening system
                    before June 30, 2006; and

          50,000    additional shares commencing on the date of grant provided
                    that the optionee has purchased at least 3.0 million starter
                    kits for the Company's consumer tooth whitening system
                    before June 30, 2006.

          (b) An option shall be exercisable by written notice of such exercise,
in the form prescribed by the Board of Directors, to the Secretary or Treasurer
of the Company at its principal office. The notice shall specify the number of
shares for which the option is being exercised (which number, if less than all
of the shares then subject to exercise, shall be 50 or a multiple thereof) and
shall be accompanied by payment (i) in cash or by check in the amount of the
full exercise price of such options, or (ii) in such other manner as the Board
shall deem acceptable. No shares shall be delivered upon exercise of any option
until all laws, rules and regulations, which the Board of Directors may deem
applicable, have been complied with.

                                       3

          (c) The person exercising an option shall not be considered a record
holder of the stock so purchased for any purpose until the date on which he is
actually recorded as the holder of such stock in the records of the Company.
