            Re:   Milestone Scientific Inc ("Milestone")
                  Payment of Deferred Compensations

Dear Len:

      This will confirm that Milestone has agreed to issue to you and that you
have agreed to accept from Milestone 614,183 units in payment of $491,346 in
compensation, specifically, your salary as Chief Executive Officer of Milestone,
which you voluntarily have deferred since August 5, 2000. Each unit will consist
of one share of Milestone common stock and one warrant to purchase an additional
share of such common stock. The warrants will be exercisable at $.80 per share
through January 31, 2003, thereafter at $1.00 per share through January 31,
2004, and thereafter at $2.00 per share through January 31, 2007, at which time
they will expire. The warrants also will have antidilution protection against
capital changes.

      Milestone will use its best efforts to file with the Securities and
Exchange Commission as soon as reasonably possible, but not later than June 30,
2002, a registration statement under the Securities Act of 1933, as amended (the
"Securities Act") on Form S-3, registering the reoffer, resale or other
disposition of the shares included in the units and the underlying the warrants
and will use its best efforts to cause the registration statement to become
effective as soon as possible after filing.

      By signing this letter, you confirm that (i) you are an "accredited
investor" within the meaning of Rule 215 of the Rules and Regulations under the
Securities Act, and (ii) you have acquired the units for investment and
acknowledge that the securities cannot be resold or otherwise disposed of until
they are registered under the Securities Act and any applicable state securities
laws or an exemption from registration is available.

      Since the securities will not be registered at the time of issuance, the
certificates representing the shares and warrants underlying the units delivered
to you will bear the following legends, respectively:

      THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
      THE SECURITIES ACT OF 1933, AS AMENDED

<PAGE>

      (THE "ACT"), AND MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR ASSIGNED
      EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR IN
      A TRANSACTION WHICH IS EXEMPT FROM REGISTRATION UNDER THE ACT.

      NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK WHICH MAY BE ACQUIRED
      UPON THE EXERCISE HEREOF, AS OF THE DATE OF ISSUANCE HEREOF, HAS BEEN
      REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND
      MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR ASSIGNED EXCEPT PURSUANT TO
      AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR IN A TRANSACTION
      WHICH IS EXEMPT FROM REGISTRATION UNDER THE ACT.

            Please acknowledge your agreement and understanding of the above
provisions by signing and dating a copy of this letter and returning it to us by
facsimile and mail. The securities will be delivered to you promptly after
receipt of your acknowledgement.

                                          Sincerely,

                                          MILESTONE SCIENTIFIC INC.
