      WHEREAS, MHTX, Novint, and Anderson signed a Research and Development and
License Agreement dated as of June 24, 2000 (the "R&D Agreement") pursuant to
which (i) MHTX had the right to receive 36,606 shares of Novint Common Stock in
exchange for MHTX's agreement to fund (or procure the funding of) $1,500,000
initially, and such significant additional amounts as MHTX and Novint agreed,
and (ii) Novint agreed to perform, and to apply MHTX's funding in payment of,
certain research and development services; a photocopy of the R&D Agreement is
attached to this Agreement; and,

      WHEREAS, as of the date of this Agreement, MHTX has paid to Novint
$1,220,000 of such funding and has agreed to deliver the remaining $280,000 of
such funding; and,

<PAGE>

      WHEREAS, the parties have agreed to terminate the Research and Development
and License Agreement, including without limitation MHTX's obligations to
continue funding beyond the initial $1.5 million.

      NOW, THEREFORE, upon good and valuable consideration, the receipt and
legal sufficiency of which are hereby acknowledged, the parties hereto do hereby
agree as follows:

      1. PURCHASE AND SALE OF NOVINT SHARES. Contemporaneously with the signing
of this Agreement, Novint agrees to issue and sell to MHTX, and MHTX agrees to
purchase, 40,672 shares of Novint Common Stock which will constitute 48.65% of
all issued and outstanding shares of Novint Common Stock on an undiluted basis
(ie., before provision for options granted as of the date of this Agreement or
to be granted pursuant to agreements with employees or pursuant to other stock
option plans adopted by Novint). As consideration for the 40,672 shares, MHTX
(i) has delivered to Novint $1,220,000, (ii) will deliver to Novint $280,000,
and (iii) will deliver to Novint on or before April 20, 2001, a stock
certificate representing 1,000,000 shares of MHTX Common Stock (the "MHTX
Shares"). It is understood and agreed that, following the purchase by MHTX of
the additional MHTX Shares, ownership of Novint's issued and outstanding shares
of common stock will be as follows:

      Anderson:               40,672 shares
      MHTX:                   40,672 shares ("MHTX Novint Stock")
      Other Shareholders       2,250 shares


                                       3
<PAGE>

It is understood and agreed that, in addition to the foregoing, there will be
options to purchase 1405 shares of Novint Common Stock, 4,000 shares of Novint
Preferred Stock with certain rights, restrictions, preferences and limitations
set forth in Novint's organizing documents, and 15,000 shares of Novint Common
Stock subject to the terms of an employee incentive stock option plan or other
employee agreements adopted and approved by Novint's Board of Directors. Upon
expiration and deletion of any restrictions upon the MHTX Shares, and as a
measure to protect MHTX's shareholders, Novint agrees not to sell more than
3,000 of such shares per trade upon the open market, nor more than 15,000 shares
per day, without the prior written consent of MHTX. Novint may privately
transfer all or any portion of the MHTX Stock, provided that the transferee(s)
agree to the aforesaid restrictions in writing. This covenant shall survive
termination of this Agreement. Novint warrants and represents to MHTX that the
MHTX Novint Stock, when issued to MHTX, will have been validly issued, will be
fully paid, and will be free of any liens or encumbrances, other than those
created by or imposed upon the holders thereof voluntarily by agreement or
otherwise through no action of Novint; provided, however, that the MHTX Novint
Stock will be subject to restrictions on transfer under applicable state and/or
federal securities laws and regulations. MHTX warrants and represent to Novint
that the MHTX Shares, when issued to Novint, will have been validly issued, will
be fully paid, and will be free of any liens or encumbrances, other than those
created by or imposed upon the holders thereof voluntarily by agreement or
otherwise through no action of MHTX; provided, however, that the MHTX Shares
will be subject to restrictions on transfer under applicable state and/or
federal securities laws and regulations.

      2. REGISTRATION OF SHARES, PIGGYBACK REGISTRATION RIGHTS AND LEGEND. MHTX
shall make a good faith effort to effect a registration of at least 250,000
shares of the MHTX Shares to be received by Novint pursuant to this Agreement by
preparing and filing with the Securities Exchange Commission an appropriate
registration statement pursuant to applicable federal securities laws and
regulations, and seeking the declaration or ordering of the effectiveness of
such registration statement. In connection with the filing of any such
registration statement, MHTX will (i) promptly give to Novint written notice
thereof, which notice shall also indicate all requirements or conditions to
which such registration is subject, all in MHTX's sole discretion and (ii)
include in such registration(and any related qualification under blue sky laws
or other compliance), and in any underwriting involved therein, the 250,000
shares held and owned by Novint and specified in a written request or request
made by Novint within 10 days after receipt of such written notice from MHTX to
Novint. Until such registration is effective, all shares to be issued to Novint
pursuant to this Agreement shall bear substantially the following legend:

      "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
      1933, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN
      THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE
      SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE
      CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED, OR UNLESS SOLD
      PURSUANT TO RULE144(k) OF SUCH ACT."

Novint acknowledges and agrees that the timing of MHTX's efforts to effect a
registration of shares is within MHTX's sole discretion, and that such
registration efforts will be intended to accomplish MHTX corporate purposes in
addition to the transactions contemplated herein. Notwithstanding the foregoing,
MHTX presently intends to initiate such efforts as soon as reasonably
practicable after the date of this Agreement, but in no event prior to the
filing of its year 2000 form 10-K. With regard to shares to be issued by MHTX to


                                       5
<PAGE>

Novint pursuant to this Agreement, MHTX neither guarantees, warrants nor
represents to Novint that: (i) such shares will ultimately be granted
registration status by the Securities and Exchange Commission or other cognizant
government entity or that registered status, if granted, will be maintained;
(ii) any such registration will be accomplished within a predetermined period of
time; or (iii) that such shares prior to registration or at any other times will
not be restricted from resale or transfer or otherwise subject to disclosure or
other requirements pursuant to SEC Rule 144 or other applicable laws, rules or
regulations. Novint has sought and received independent legal and accounting
advice concerning these and related securities law and tax issues and
consequences and rely solely upon such advice in entering into this Agreement.
Novint expressly acknowledges and agrees that no officer, director, attorney,
accountant, employee or contractor of MHTX has provided Novint with legal,
accounting, or business advice concerning any aspect of this Agreement or the
transactions contemplated hereunder, and Novint freely assumes any tax or other
risks associated with same.

      3. SHAREHOLDER AGREEMENTS. MHTX and Anderson agree to vote their shares to
give effect to the following management and share restrictions:

            3.1 It is agreed that, other than the securities described in
paragraph 1 above, no other securities of Novint shall be issued or authorized
in the absence of formal approval of the board of directors of Novint.

            3.2 There shall be five (5) seats on the Novint board of directors
elected by Novint's shareholders in accordance with its Bylaws. MHTX and
Anderson agree to vote their shares to elect Anderson and Marvin Maslow as
Directors and to elect Anderson as Chairman of the Board. Initially MHTX shall
be entitled to specify two (2) directors, and Novint shall be entitled to
specify two (2) directors, it being understood that the fifth director shall be
selected by the other (4) directors. As of the date of this Agreement, Thomas
Anderson and Edwin H. Barsis are the two directors specified by Novint. Marvin
Maslow and Scott L. Bach are the two directors specified by MHTX.

<PAGE>

            3.3 Novint is presently considering becoming a public company either
through an initial public offering or through a transaction by which Novint
(and/or its successors and assigns) are acquired by an existing public company
whose sole purpose subsequent to such acquisition shall be to carry on the
affairs of Novint ("Novint Public Co."). MHTX shall act as an uncompensated
facilitator and advisor to Novint in connection with the foregoing. Anderson and
MHTX agree to vote their shares in Novint to maintain the ratio of ownership
percentages in Novint owned by Anderson and MHTX.

            3.4 MHTX shall not sell, assign, transfer, pledge, hypothecate,
mortgage or dispose of, by gift or otherwise, or in any way encumber, all or any
part of the MHTX Novint Shares (as defined below) owned or to be owned by it
except in compliance with the terms of this Agreement. For purposes of this
Agreement, the term "Shares" shall mean and include the MHTX Novint Stock and
any other portion of the shares of stock of Novint of any class or any other
share or shares of capital stock (or rights, options or warrants to acquire such
shares) of Novint (or its successors) owned by MHTX, whether presently held or
hereafter acquired.

            3.5 Prior to the time that Novint becomes Novint Public Co., MHTX
may not sell, assign, transfer or otherwise dispose of any or all MHTX Novint
Shares owned by it to a third party unless (i) MHTX shall have received a bona
fide arm's length offer to purchase such MHTX Novint Shares from such third
party, and (ii) MHTX first submits a written offer (the "Offer") to Novint
identifying the third party to whom such MHTX Novint Shares are proposed to be
sold and the terms of the proposed sale and offering to Novint the opportunity
to purchase such MHTX Novint Shares on terms and conditions, including price,
not less favorable to Novint than those on which MHTX proposes to sell such MHTX
Novint Shares to any other purchaser.


                                       7
<PAGE>

                  Novint shall act upon the Offer as soon as practicable after
receipt thereof, and in no event later than thirty (30) days after receipt
thereof. In the event that Novint shall elect to purchase all or a part of the
MHTX Novint Shares covered by the Offer, Novint shall, within such thirty (30)
day period, (i) communicate in writing such election to purchase to MHTX, which
communication shall be delivered by hand or mailed to MHTX at the address shown
by Novint's records or at such other address furnished to Novint and shall, when
taken in conjunction with the Offer, be deemed to constitute a valid, legally
binding and enforceable agreement for the sale and purchase of the MHTX Novint
Shares covered thereby; and (ii) pay (or cause to be paid) to MHTX the purchase
price in full.

                  In the event that Novint does not purchase the MHTX Novint
Shares offered by MHTX pursuant to the Offer, all of such MHTX Novint Shares may
be sold by MHTX at any time following the thirtieth (30th) day after receipt of
the Offer by Novint, provided that the purchaser of the MHTX Novint Shares shall
agree in writing to abide by all of the provisions hereof. Any such sale shall
be to the person originally named in the Offer as the proposed purchaser or
transferee and shall be at not less than the price and upon other terms and
conditions, if any, not more favorable to such purchaser than those specified in
the Offer. Any MHTX Novint Shares sold after such 30-day period, to a different
purchaser, at a lower price or otherwise on more favorable terms shall be
subject to the requirements of a prior offer pursuant to this Section.

                  The provisions of this Section 3.5 shall terminate immediately
upon the effectiveness of an underwritten initial public offering on a firm
commitment basis pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "Securities Act"), covering the offer
and sale of Voting Common Stock for the account of Novint, in which the
aggregate gross proceeds to Novint are acceptable to its Board of Directors, or
upon the occurrence of any other procedure whereby Novint becomes Novint Public
Co.

            3.6 If Novint becomes Novint Public Co., then upon expiration and
deletion of any restrictions upon the MHTX Novint Shares, and as a measure to
protect Novint Public Co.'s shareholders, MHTX agrees not to sell more than
3,000 of such shares per trade upon the open market, nor more than 15,000 shares
per day upon the open market, without the prior written consent of Novint. MHTX
may privately transfer all or any portion of the MHTX Novint Shares, provided
that the transferee(s) agree to the aforesaid restrictions in writing. This
covenant shall survive termination of this Agreement.

            3.7 Prior to Novint becoming Novint Public Co., any transferee of
Novint stock originally issued to MHTX, whether through purchase or otherwise,
shall agree to abide by any voting restrictions described in this contract,
including but not limited to voting with respect to the board of directors and
its chairman, prior to transfer of said stock. This covenant shall survive
termination of this Agreement.

limited to, with respect to any license of Novint Technologies (as defined in
