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

     AGREEMENT made as of this 22nd day of June, 2001 (the "Agreement"), between
Spacial Corporation, a Delaware corporation ("Spacial"), with offices at 92
Brown Place, Bronx, New York 10454, James J. Solano Sr. ("Solano"), with an
address c/o Spacial Corporation, 92 Brown Place, Bronx, New York 10454, The

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

     1.   Spacial, Solano and the Trust are parties to a Share Exchange
          Agreement, dated as of June 22, 2001, (the "Exchange Agreement")
          pursuant to which Solano has received 1,785,000 shares of Special
          Common Stock $.001 par value ("Common Stock") and the Trust has
          received 10,000,000 shares of Common Stock.

     2.   Spacial desires to obtain certain financing wherein it wishes to sell
          up to 1,000,000 shares of its Common Stock (the "Financing").

     3.   Due to Solano's and the Trust's ownership of a substantial number of
          shares of Common Stock, each of them would benefit materially if
          Spacial completed the Financing.

     4.   Solano and the Trust wish to expedite the Financing without affecting
          the ownership interest of other Spacial shareholders in Spacial.

     5.   Accordingly, Solano and the Trust have agreed to deposit in escrow
          with the Escrow Agent a total of 1,000,000 shares of Common Stock
          received by them under the Exchange Agreement, part or all of which
          shall be returned to Spacial for cancellation in the event the
          Financing is consummated, all as provided in this Agreement.

     6.   The Escrow Agent has agreed to act as escrow agent to hold the shares
          of Spacial Common Stock to be held in escrow in accordance with the
          terms of this Agreement.

                                        1

         NOW, THEREFORE, it is agreed as follows:

     1. Deposit of Escrow Shares; Establishment of Escrow.
        --------------------------------------------------

     Concurrently with the execution and delivery of this Agreement, Solano is
delivering to the Escrow Agent Spacial Stock Certificate No. ___ representing
151,464 shares of Common Stock, together with a stock power executed in blank by
Solano, and the Trust is delivering to the Escrow Agent Spacial Stock
Certificate No. ___ representing 848,536 shares of Common Stock, together with a
stock power executed in blank by the trustee on behalf of the Trust (such
certificates together with the shares represented thereby being referred to
herein as the "Escrow Shares"). The parties hereby appoint Snow Becker Krauss
P.C. as the Escrow Agent (i) to hold the Escrow Shares, the stock powers and
such other securities or property (other than cash) delivered to the Escrow
Agent in connection with or with respect to such Escrow Shares (the "Escrow
Property") and (ii) to distribute the Escrow Property as herein provided. The
Escrow Agent hereby acknowledges receipt of the Escrow Property.

     2. Release of Escrow Shares.
        ------------------------

     (a) If Spacial expects to close the Financing within 90 days after the date
hereof, Spacial shall give a notice to the Escrow Agent, not later than five (5)
business days before the proposed closing date of such Financing (the "Proposed
Closing Date"), instructing the Escrow Agent to deliver the Escrow Property to
Spacial at the closing of such Financing (the "Closing"), which notice shall
also specify the Closing Date, the location of the Closing, and the total number
of shares of Common Stock to be issued to investors at such Closing. Spacial
shall send a copy of such notice to Solano and the Trust.

     (b) If the Escrow Agent receives the notice provided for in Section 2(a)
(the "Closing Notice") and has not received by 5:00 p.m. New York time on the
business day immediately preceding the Proposed Closing Date a written notice
from Solano or the Trust objecting to Spacial's instructions, then the Escrow
Agent shall deliver the Escrow Property to Spacial at the Closing. If Spacial's
Closing Notice states that Spacial will be issuing fewer than 1,000,000 shares
of Common Stock at the Closing, then as a condition to the Escrow Agent's
delivery of the Escrow Property to Spacial, Spacial shall deliver to the Escrow
Agent (i) one or more certificates registered in the name of Solano representing
a number of shares of Common Stock (and such other securities or property
constituting the Escrow Property delivered to Spacial) equal to 15.1464% of the
difference between 1,000,000 and the number of shares issued at such closing
(such difference being referred to herein as the "Excess Amount") and (ii) one
or more certificates registered in the name of the Trust representing a number
of shares of Common Stock (and such other securities or property constituting
the Escrow Property delivered to Spacial) equal to 84.8536% of the Excess
Amount. Promptly after the Escrow Agent's receipt of such stock certificates and
other property, if any, delivered to it pursuant to the preceding sentence, the

                                        2
<PAGE>

Escrow Agent shall deliver such stock certificates and other property to Solano
and the Trust, as applicable.

     (c) If the Escrow Agent receives, on or before 5:00 p.m. New York time on
the business day immediately preceding the Proposed Closing Date, a written
notice from Solano or the Trust, with a copy thereof sent to Spacial, objecting
to Spacial's Closing Notice, the Escrow Agent shall take no action and make no
delivery of the Escrow Property except in accordance with (A) written
instructions signed by the Spacial, Solano and the Trust or (B) an order of a
court of competent jurisdiction. In the event of such an objection to notice,
the Escrow Agent shall be empowered in its sole discretion to deposit the Escrow
Property with a court of competent jurisdiction and to institute an action of
interpleader or other such action to resolve the dispute.

     (d) If no Financing is scheduled to occur within 90 days after the date
hereof, but during such period Spacial has entered into a letter of intent or
other agreement with a person or entity that proposes to provide or obtain
Financing for Spacial, then Spacial shall send a notice thereof to the Escrow
Agent, with a copy thereof to Solano and the Trust. If a Closing of the sale of
Common Stock as contemplated by such letter of intent is scheduled to occur
within 180 days after the date of such letter of intent, then Spacial shall give
a Closing Notice to the Escrow Agent, Solano and the Trust as provided in
Section 2(a) with respect to such Closing.

     (e) If Spacial fails to provide a Closing Notice to the effect that the
Closing of the contemplated financing is scheduled to occur within 90 days after
the date hereof or within 180 days after the date of a letter of intent as
provided in Section 2(d), then the Escrow Agent shall deliver the Escrow
Property to Solano and the Trust within ten (10) days after expiration of the
applicable period.

     3. Adjustments to the Number of Escrow Shares.
        -------------------------------------------

     If Spacial shall effect any stock split, distribution, recapitalization,
subdivision, reclassification or other similar event during the term of this
Agreement, the Escrow Shares shall be subject to pro rata adjustment so
immediately thereafter the Escrow Shares held in escrow shall be correspondingly
increased to reflect an increase in the outstanding Common Stock or decreased to
reflect a decrease in the outstanding Common Stock.

     4. Rights Regarding Escrow Shares.
        -------------------------------

     For so long as the Escrow Agent is holding the Escrow Shares under this
Agreement, Solano and the Trust shall retain full voting rights with respect to
the Escrow Shares registered in their respective names, and Spacial shall pay
all cash dividends or other property distributions other than securities issued
with respect to its stock, with respect to the Escrow Shares directly to Solano
and the Trust, as the case may be. If Spacial issues securities or distributes
property other than cash to the holders of its Common Stock, Spacial shall
deliver the securities issuable or

                                        3
<PAGE>

other property distributable with respect to the Escrow Shares to the Escrow
Agent, which securities or other property shall be registered in the names of
Solano and the Trust, as appropriate, and held in escrow as herein provided. In
the event of a reverse stock split or other reorganization that results in a
smaller number of issued and outstanding shares of Common Stock or other
securities, the Escrow Shares shall automatically represent such smaller number
of shares without any requirement on the part of the Escrow Agent to deliver or
exchange the Escrow Shares for other shares of Common Stock or other securities.
The Escrow Agent shall possess no right to tender or otherwise transfer the
Escrow Shares other than as set forth in this Agreement, and if the Escrow Agent
receives instructions on tender or other transfer thereof other than as
contemplated by Section 2, the Escrow Agent shall promptly notify Spacial,
Solano and the Trust in writing thereof, but shall not take any other action
with respect thereto, except as provided in this Escrow Agreement or as
instructed by Spacial, Solano and the Trust.

     5. Term.
        ----

     This Escrow Agreement shall continue in effect until the earlier of (i) the
Escrow Agent's delivery of all Escrow Property in accordance with the terms of
this Agreement or (ii) the Escrow Agent's receipt of written notice of
termination signed by Spacial, Solano and the Trust, directing the disposition
of the Escrow Shares, and the disposition thereof by the Escrow Agent pursuant
to such direction.

     6. Obligations of the Escrow Agent.
        -------------------------------

     The Escrow Agent shall not have any liability under, or duty to inquire
into, the terms and provisions of any agreement, other than this Agreement. Its
duties are ministerial in nature, and the Escrow Agent shall not incur any
liability whatsoever so long at it has acted in good faith, except for willful
misconduct or gross negligence. The Escrow Agent shall not have any duties or
responsibilities hereunder except as expressly set forth herein; shall have no
investment responsibility with respect to funds or other property held
hereunder; and shall have no responsibility for ascertaining or taking any
action with respect to calls, conversions, exchanges, maturities, tenders, or
other matters relating to any property held by it hereunder, whether or not the
Escrow Agent has or is deemed to have knowledge or notice of such matters, or
taking any steps to preserve rights against any parties with respect to any
property held by it hereunder.

     The Escrow Agent may consult with counsel of its choice, including in-house
counsel, and shall not be liable for any action taken, suffered or omitted by it
in accordance with the advice of such counsel. The Escrow Agent shall not be
bound by any modification, amendment, termination, cancellation, rescission or
supersession of this Agreement unless the same shall be in writing and signed by
Spacial, Solano, the Trust and the Escrow Agent, if its duties as Escrow Agent
hereunder are affected thereby, unless it shall have given its prior written
consent thereto.

     In the event that the Escrow Agent shall be uncertain as to its duties or
rights hereunder or shall receive instructions, claims or demands from any party
to this Agreement which, in the

                                        4
<PAGE>

Escrow Agent's opinion, conflict with any of the provisions of this Agreement,
it shall be entitled to refrain from taking any action and its sole obligation
shall be to keep safely all property held in escrow until it shall be directed
otherwise in writing by the parties or by a final order or judgment of a court
of competent jurisdiction. Alternatively, the Escrow Agent may, in its sole
discretion, deposit with the Clerk of any court of competent jurisdiction, any
and all funds, securities and other property held by it pursuant thereto and
thereupon and, shall stand fully relieved and discharged of any further duties
hereunder.

     The Escrow Agent shall not incur any liability for following the
instructions herein contained or expressly provided for, or written instructions
given by Spacial, Solano or the Trust. The Escrow Agent shall be entitled to
rely upon any notice, certificate, affidavit, letter, document, or other
communication which is, upon reasonable verification, believed by the Escrow
Agent to be genuine and to have been signed or sent by the proper party or
parties, and may rely on statements contained therein without further inquiry or
investigation. Release by the Escrow Agent of the Escrow Shares shall not
constitute a distribution by Escrow Agent, or a legal opinion of Escrow Agent
that said release is lawful, or that said release does not violate any
Securities laws, or other agreements.

     The Escrow Agent shall not have any responsibility for the genuineness or
validity of any document or other item deposited with it and any liability for
action in accordance with any written instructions or certificates given to it
hereunder and believed by it to be signed by the proper parties.

     The Escrow Agent shall not be required to institute legal proceedings of
any kind and shall not be required to initiate or defend any legal proceedings
or enforcement/investigatory actions of any kind which may be instituted against
it in respect of the subject matter of these instructions. If it does elect to
act it will do so only if it is indemnified to its satisfaction against the cost
and expense of such defense or initiation.

     7. Release of Escrow Agent.
        -----------------------

     The Escrow Agent may at any time resign hereunder by giving written notice
of its resignation to Spacial, Solano and the Trust, at their addresses set
forth in this Agreement, at least 30 days prior to the date specified for such
resignation to take effect, and upon the effective date of such resignation, all
property then held by the Escrow Agent hereunder shall be delivered by it to
such person as may be designated by Spacial, Solano, or the Trust in writing,
whereupon all the Escrow Agent's obligations hereunder shall cease and
terminate. If no such person shall have been designated by such date, all
obligations of the Escrow Agent hereunder shall nevertheless cease and
terminate. The Escrow Agent's sole responsibility thereafter shall be to keep
safely all property then held by it and to deliver the same to a person
designated by Spacial, Solano and the Trust or in accordance with the directions
of a final order or judgment of a court of competent jurisdiction.

                                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

               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.
