                    SECTION 2.   Security for Obligations.   The Agreement

          secures  and  the   Pledged  Collateral  is   security  for   the
          indefeasible payment in  full when due,  whether at maturity,  by
          acceleration or
          otherwise the obligations of Pledgor to Pledgee.
                    SECTION 3.    Delivery of Pledged  Collateral.  All  of

          the certificates  representing the  Pledged Collateral  shall  be
          delivered  to  Baratta  &  Goldstein,  as  Pledge-Escrow  Agents,

          ("Separation"), which default shall  specifically and only  refer

          right to exchange such stock certificates in the name of  Pledgee


                                          3



          and/or take the action  it deems appropriate  to sell, assign  or
          transfer all or  any part of  said stock in  satisfaction of  the
          outstanding financial obligation of Pledgor to the Pledgee.
                    The Pledgee will have the discretion to sell by  public
          or private sale  the shares of  stock herein and  as long as  the
          provisions of the Uniform Commercial Code concerning the sale of
          collateral are adhered to, then and in that event, Pledgee  shall
          be permitted, at its discretion, to  retain said shares of  stock
          or sell said shares of stock  to a third party or entity  subject
          to the applicable  rules and  regulations of  the Securities  and
          Exchange Act as made and promulgated.
                    At the written instruction of the Pledgor to the Pledge
          Agent to deliver said pledged shares against payment to  Pledgee,
          the Escrow Agent  shall notify  the Pledgor.   Payments  received

          paid to Pledgor.  Pledgee and Pledgor indemnify and hold harmless
          the Pledge-Escrow Agents from any actions  as per the request  to
          sell and  deliver said  shares  as long  as  payment is  made  to
          Pledgee or its successors in interest.

                    (c)  The pledge of the  Pledged Shares pursuant  hereto

          true copy of said Agreement is annexed hereto and made a part
          hereof, and Pledgor  and Pledgee  recognize and  agree that  said
          Agreement and the  terms contained therein,  with respect to  the
          212,700 shares of common stock of Pledgee, will be binding on all

          of the  Pledged  Collateral  pursuant hereto  or  the  execution,


                                          5

          the remedies  in  respect  of  the  Pledged  Collateral  pursuant
          hereto,  except  as  may  be  required  in  connection  with  the
          disposition of  the  Pledged  Collateral by  laws  affecting  the
          offering and sale of securities generally.
                    (e)  Pledgor has full power, authority and legal  right
          to pledge all the Pledged Collateral pursuant hereto.
                    (f)  Pledgor acknowledges  that he  was represented  by
          independent counsel.
                    (g)  Pledgor  warrants  that  he  qualifies  under  the
          exemption relied upon by Pledgee of  the Securities Act and  that

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

          agrees that at any time and from time to time, at the  reasonable
          expense of  Pledgor, Pledgor  will promptly  execute and  deliver
          such further  instruments and  documents, and  take such  further
          action, as may be necessary or desirable, or that the Pledgee may
          request, in order  to perfect and  protect any security  interest
          granted or  purported  to be  granted  hereby or  to  enable  the
          Pledgee  to  exercise  and  enforce  their  rights  and  remedies
          pursuant hereto with respect to any of the Pledged Collateral.
                    Pledgor agrees  to  defend  the title  to  the  Pledged
          Collateral and the lien thereon and security interest therein  of
          the Pledgee against the claim of any person and to maintain and


                                          6



           preserve such lien and security  interest until payment in  full
          of the obligations of Pledgor to Pledgee.
                    SECTION 6.  Voting Rights; Dividends; etc.
                                ------------------------------

                    (a)  As long  as no default or  event of default  shall
          have occurred and be continuing;
                         (i)  As long as there is no prejudice to Pledgee's
          rights with respect to the  collateral pledged, Pledgor shall  be
          entitled to  exercise any  and all  voting and  other  consensual
          rights pertaining to the Pledged  Collateral or any part  thereof
          for any purpose not inconsistent with the terms hereof.  However,
          no Pledgor shall  exercise or  refrain from  exercising any  such
          right, if in the Pledgee's reasonable judgment, such action would
          (A) have a material  adverse effect on the  value of the  Pledged
          Collateral  or  any  part  thereof  or  the  Pledgee's  interests
          therein,  or  (B)   authorize  or  effect   (x)  a   dissolution,
          liquidation, merger, or sale of all  or substantially all of  the
          assets of MTI,  (y) a material  amendment of  the Certificate  of
          Incorporation of MTI, or (z) an  alteration of the voting  rights
          of the stock  of MTI; and  provided further,  that Pledgor  shall
          give the Pledgee  at least five  (5) days written  notice of  the
          manner in  which  it intends  to  exercise, or  the  reasons  for
          refraining from exercising.  It is understood, however, that  the
          voting by Pledgor of any of  the Pledged Shares for or  Pledgor's
          consent to the  election of  directors at  a regularly  scheduled
          annual or  other meeting  of stockholders,  shall not  be  deemed


                                          7



          inconsistent with the terms of this  Agreement, and no notice  of
          any such voting or consent need be given to Pledgee.
                    (ii) Pledgor shall be  entitled to  receive and  retain
          any and all dividends and other distributions paid in respect  of
          the Pledged Collateral, other than any and all
                         (A)  dividends  or  other  distributions  paid  or
          payable other than  in cash in  respect of,  and instruments  and
          other property received, receivable  or otherwise distributed  in
          respect of, or in exchange for, any of the Pledged Collateral;
                         (B)  dividends  or  other  distributions  paid  or
          payable in cash in  respect of any of  the Pledged Collateral  in
          connection with a partial or total liquidation or dissolution  or
          in connection with  a reduction  of capital,  capital surplus  or
          paid-in surplus; and
                         (C)  cash paid, payable  or otherwise  distributed
          in redemption  of,  or  in  exchange  for,  any  of  the  Pledged
          Collateral, all of  which shall  be, and  all of  which shall  be
          forthwith delivered to Pledgee  to hold as,  part of the  Pledged
          Collateral and,  if received  by Pledgor,  shall be  received  in
          trust of the benefit  of the Pledgee,  segregated from the  other
          property or funds of Pledgor, and forthwith delivered to  Pledgee
          as part of the Pledged Collateral in the form received (with  any
          necessary endorsement).
                    (b)  Upon the occurrence and during the continuance  of
          a default or event of default:


                                          8



                         (i)  Upon notice to Pledgor by Pledgee, all rights
          of Pledgor to  exercise the  voting and  other consensual  rights
          which it  would otherwise  be entitled  to exercise  pursuant  to
          Section 6 (a) (i) hereof shall  cease, and all such rights  shall
          thereupon become vested in the Pledgee, who shall thereupon  have
          the sole  right  to exercise  such  voting and  other  consensual
          rights.
                         (ii) All  rights   of  Pledgor   to  receive   the
          dividends.
                    SECTION 7.    Transfers and  Other  Liens;  Additional
                                  ----------------------------------------

          Shares.
          ------

                    (A)  Pledgor agrees that it will not:
                         (i)  sell, assign,  or  otherwise dispose  of,  or
          grant any option or warrant with  respect to, any of the  Pledged
          Collateral, or
                         (ii) create or permit to exist any lien,  security
          interest, or other charge or encumbrance upon or with respect  to
          any of the Pledged  Collateral, except for the  lien in favor  of
          the Pledgee pursuant hereto.
                    (b)  Pledgor agrees that it will:
                         (i)  cause each issuer of  the Pledged Shares  not
          to  issue  any  stock  or  securities   in  addition  to  or   in
          substitution for the Pledged Shares except to Pledgor;



                                          9



                         (ii) pledge,  immediately  upon  its   acquisition
          (directly or indirectly) thereof, any and all shares of stock  of
          any person  who, after  the date  of  this Agreement,  becomes  a
          Subsidiary of Pledgee.
                    SECTION 8.  Pledgee Appoints Attorney-in-Fact.  Pledgor
                                ---------------------------------

          hereby irrevocably  appoints  Pledgee as  Pledgor's  attorney-in-
          fact, with the full authority in  the place and stead of  Pledgor
          and in the name of Pledgor or otherwise, from time to time in the
          Pledgee's discretion  to  take  any action  and  to  execute  any
          instrument which  Pledgee  may  deem necessary  or  advisable  to
          accomplish the  purposes of  this Agreement,  including,  without
          limitation, to receive, endorse and collect all instruments  made
          payable to Pledgor representing any dividend, interest payment or
          other distribution in  respect of the  Pledged Collateral or  any
          part thereof  and to  give full  discharge for  the same.    This
          power, being coupled with an interest, is irrevocable.
                    SECTION 9.  Remedies upon Default.  If any default  or
                                ---------------------

          event of default shall have occurred and be continuing:
                    (a)  (i)  Pledgee  may  exercise  in  respect  of   the
          pledged Collateral,  in addition  to  other rights  and  remedies
          provided for herein or otherwise available to it, all the  rights
          and remedies of a secured party in case of a default by a  debtor
          under the  Uniform Commercial  Code, and  the Pledgee  may  also,
          without notice  except  as  specified  below,  sell  the  Pledged


                                         10



          Collateral or any part thereof in  one or more parcels at  public
          or private sale, at any exchange or broker's board, at any of the
          Pledgee's offices or elsewhere, for cash, on credit or for future
          delivery, and  upon such  other terms  as  the Pledgee  may  deem
          commercially reasonable.
                         (ii) Pledgor agrees that, to the extent notice  of
          sale shall be required by law,  at least ten (10) days notice  to
          Pledgor of the  time and  place of any  public sale  or the  time
          after which  any private  sale is  to  be made  shall  constitute
          reasonable notification.  The Pledgee  shall not be obligated  to
          make any sale of Pledged Collateral regardless of notice of  sale
          having been given.  The Pledgee may adjourn any public or private
          sale from time  to time  by announcement  at the  time and  place
          fixed therefor, and  such sale  may, without  further notice,  be
          made at the time and place to which it was so adjourned.  Pledgor
          hereby waives any claims against the Pledgee arising by reason of
          the fact that the  price at which any  of the Pledged  Collateral
          may have been sold at such  private sale was less than the  price
          which might have  been obtained  at a  public sale,  even if  the
          Pledgee accepts the  first offer received  and do  not offer  the
          Pledged Collateral to more than one offeree.
                    (b)  All proceeds received will be applied first to the
