                                LOCK-UP AGREEMENT
                                -----------------

     This LOCK-UP AGREEMENT (the "Lock-Up Agreement") dated as of June 22nd
2001, is made by and among Spacial Corporation, a Delaware Corporation (the
"Company") and each of James A. Prestiano ("Prestiano"), James J. Solano, Sr.
("Solano"), Norman A. Ponder ("Ponder"), the Trust Under Agreement Dated June
30, 1989 (the "Trust"; and collectively with Prestiano, Solano and Ponder, the
"Restricted Shareholders"), with respect to shares of the Company's common
stock, par value $.001 per share (the "Common Stock"), beneficially owned by
such Restricted Shareholders.

                              W I T N E S S E T H:
                              --------------------

     1.   The Company has entered into a Share Exchange Agreement (the "Share
          Exchange Agreement") with Waste Recovery Technology Corporation
          ("WRT") and all of its shareholders (the "WRT Shareholders"), wherein
          the Company issued an aggregate of 13,160,000 shares of Common Stock
          to the WRT Shareholders, in exchange for all of the issued and
          outstanding WRT Stock (the "Share Exchange"). All capitalized terms in
          this Lock-Up Agreement shall have the meanings ascribed to them in the
          Share Exchange Agreement, unless otherwise specifically defined
          herein.

     2.   Solano, Ponder and the Trust (the "WRT Principals") own an aggregate
          of 1,785,000, 1,000,000, and 10,000,000 shares of Common Stock,
          respectively (collectively, the "WRT Principal Shares"), which shares
          were issued pursuant to the Share Exchange.

     3.   Prestiano owns an aggregate of 800,000 shares of Common Stock and
          warrants (the "Prestiano Warrants") to purchase 150,000 shares of
          Common Stock (the "Warrant Shares"; and collectively with said shares
          of Common Stock, and the Prestiano Warrants, the "Prestiano
          Securities").

     4.   In order to facilitate possible future financings of the Company, and
          in consideration for the Company's reduction of the length and scope
          of certain other Company's shareholders' lock-up obligations, the
          Restricted Shareholders have agreed with the Company to restrict their
          ability to transfer the Prestiano Securities and the WRT Principal
          Shares (collectively, the "Restricted Securities").

     NOW, THEREFORE, in consideration of the foregoing and the terms, conditions
and mutual covenants appearing in this Lock-Up Agreement, the parties hereto
hereby agree as follows:

Section 1.     The Lock-Up Term. The "Lock-Up Term" shall be the one-year
               period immediately following the Closing Date of the Share
               Exchange, unless otherwise extended in accordance with Section
               2(b), hereof.

Section 2.     (a) during the first six months of the Lock-Up Term, a
               Restricted Shareholder shall not offer, pledge, sell, transfer,
               assign, hypothecate, contract to sell, grant an option for the
               sale of or otherwise dispose of (collectively, "transfer") any
               Restricted

                                        1
<PAGE>

               Securities beneficially owned by such Restricted Shareholder on
               the date hereof or hereafter acquired, without the Company's
               prior written consent.

               (b) Subject to the provisions of Section 2(i) below, during the
               second six month period of the Lock-Up Term, such Restricted
               Shareholder will not sell more than fifty percent (50%) of any
               Restricted Securities owned by such Restricted Shareholder.

               (c) Subject to the provisions of Section 2(i) below, all
               Restricted Securities shall be free and clear from the
               restrictions of this Lock-Up Agreement on the day after the first
               year anniversary of the Closing Date.

               (d) During the Lock-Up Term, a Restricted Shareholder shall not
               sell short any Common Stock or otherwise sell any securities
               exchangeable for or convertible into the Common Stock, that such
               Restricted Shareholder does not own, or engage in any sale that
               is consummated by the delivery of any Common Stock borrowed by or
               from the Restricted Shareholders.

               (e) Notwithstanding the foregoing, a Restricted Shareholder may
               sell or otherwise transfer Restricted Securities provided that
               such sale is a privately negotiated transaction to a
               non-affiliated institutional investor upon prior notice to the
               Company and the other Restricted Shareholders and the transfer is
               otherwise effected in accordance with the federal and state
               securities and other laws, and such assignee executes an
               agreement to be bound by the terms of this Lock-Up Agreement. No
               transfer of the Restricted Securities will be valid without due
               compliance with the terms of this Lock-Up Agreement.

               (f) Any sales of Restricted Securities or of the other Common
               Stock or securities in violation of this Lock-Up Agreement by a
               Restricted Shareholder shall constitute an event of default under
               this Lock-Up Agreement as to such Restricted Shareholder. In the
               event of such default, in addition to any other remedy the
               Company may have at law, in equity or under this Agreement, such
               Restricted Shareholder shall pay all proceeds from the sale of
               such securities by such Restricted Shareholder, regardless of
               whether such proceeds derive from sales made prior to, concurrent
               with or subsequent to such event of default, to the Company.

               (g) Each of the Restricted Shareholders acknowledges that his
               breach or impending violation of any of the provisions of this
               Lock-Up Agreement may cause irreparable damage to the Company and
               to the Company's shareholders for which remedies at law would be
               inadequate. Each Restricted Shareholder further acknowledges that
               the provisions set forth herein are essential terms and
               conditions of this Lock-Up Agreement. Each Restricted Shareholder
               therefore agrees that the Company shall be entitled to a decree
               or order by any court of competent jurisdiction enjoining such
               impending or actual violation of any of such provisions. Such
               decree or order, to the extent appropriate, shall specifically
               enforce the full performance of

                                        2
<PAGE>

               any such provision by the Restricted Shareholders, and each of
               the Restricted Shareholders and the Company hereby consents to
               the jurisdiction of any court of competent jurisdiction, state or
               federal, sitting in the State of New York, and authorizes the
               entry on its behalf of any required appearance for such purpose.
               This remedy shall be in addition to all other remedies available
               to the Company at law or equity. If any portion of this Section
               2(g) is adjudicated to be invalid or unenforceable, this Section
               2(g) shall be deemed amended to delete therefrom the portion so
               adjudicated, such deletion to apply only with respect to the
               operation of this Section 2(g) in the jurisdiction in which such
               adjudication is made.

               (h) The Restricted Shareholders will permit an appropriate
               restrictive legend to be applied to all certificates evidencing
               the Restricted Securities giving notice of the restrictions
               imposed under this Agreement and will cause the transfer agent
               for the Company to note such restriction on the transfer books
               and records of the Company.

               (i) If, during the Lock-Up Term, the Company enters into a letter
               of intent with an underwriter (the "Underwriter"), for a firm
               commitment underwritten Public Offering of the Company's
               securities registered under the Securities Act (the "Public
               Offering"), then (i) the Lock-Up Term shall be extended with
               respect to all Restricted Securities owned by such Restricted
               Shareholder at such time, until the closing or earlier
               abandonment of the Public Offering, (ii) notwithstanding the date
               of such letter of intent, the provisions of Section 2(a) shall
               apply to all Restricted Securities and (iii) the Restricted
               Shareholders shall agree to all further restrictions, extensions
               and modifications of the terms of this Lock-Up Agreement, and any
               additional lock-up restrictions as are requested by the
               Underwriter as condition to Public Offering. The Restricted
               Shareholders agree and consent to the execution of such
               modifications, amendments or revisions to this Lock-Up Agreement,
               or a new lock up agreement, as necessary in order to effectuate
               the foregoing.

Section 3. Subject to Section 6 hereunder, this Lock-Up Agreement shall inure to
the benefit of and be binding upon the Company and its successors and assigns,
and upon the Restricted Shareholders and their heirs, executors, trustees,
administrators, legatees and legal representatives.

Section 4. Should any part of this Lock-Up Agreement, for any reason whatsoever,
be declared invalid, illegal, or incapable of being enforced in whole or in
part, such decision shall not affect the validity of any remaining portion,
which remaining portion shall remain in full force and effect as if this Lock-Up
Agreement had been executed with the invalid portion thereof eliminated, and it
is hereby declared the intention of the parties hereto that they would have
executed the remaining portion of this Lock-Up Agreement without including
therein any portion which may for any reason be declared invalid.

Section 5. This Lock-Up Agreement shall be construed and enforced in accordance
with the laws of the State of New York applicable to agreements made and to be
performed in such State without application of the principles of conflicts of
laws of such State.
