                             BORROWER SECURITY AGREEMENT
                             ---------------------------



                    THIS BORROWER SECURITY AGREEMENT (this "Agreement"),
          dated as of August 22, 1997, is executed by and between American
          Eco Funding Corp., a corporation organized under the laws of the
          State of Delaware, having its chief executive office at 11011
          Jones Road, Houston, Texas 77070 (the "Grantor"), and Union Bank
          of California, N.A., as "Agent" for itself and for the other
          "Secured Parties" under the "Credit Agreement" (as such terms are
          defined below). 

                    PRELIMINARY STATEMENT.  The Grantor has entered into a
          certain Credit and Guaranty Agreement of even date herewith among
          the Grantor, American Eco Corporation (the "Parent Guarantor"),
          which owns 100% of the issued and outstanding common stock of the
          Grantor, as guarantor of the Grantor's obligations thereunder,
          the institutions from time to time party thereto as lenders (the
          "Lenders"), the institutions from time to time party thereto as
          issuing banks (the "Issuing Banks"), and Union Bank of
          California, N.A., as agent (in such capacity, the "Agent") for
          the Lenders and the Issuing Banks and the other Secured Parties
          (as the same may be amended, restated, supplemented or otherwise
          modified from time to time, the "Credit Agreement"; unless
          otherwise defined herein, capitalized terms used herein shall
          have the meanings ascribed to them in the Credit Agreement)
          providing for the making of Loans to the Grantor for the benefit
          of the Grantor and/or other Subsidiaries of the Parent Guarantor,
          and for the issuance of Letters of Credit for the account of the
          Grantor and/or other Subsidiaries of the Parent Guarantor.  It is
          a condition precedent to the extensions of credit under the
          Credit Agreement that the Grantor shall have granted the security
          interest contemplated by this Agreement, in order to secure its
          obligations under the Credit Agreement.

                    NOW, THEREFORE, in consideration of the premises set
          forth herein and in order to induce the Lenders to make Loans and
          the Issuing Banks to issue Letters of Credit under the Credit
          Agreement, the Grantor hereby agrees with the Agent for its
          benefit and the ratable benefit of the Secured Parties as
          follows:

                    SECTION 1.  Grant of Security.  The Grantor hereby
                                -----------------
          grants to the Agent for its benefit and the ratable benefit of
          the Secured Parties, a security interest in all of the Grantor's
          right, title and interest in and to the following, in each case
          whether now owned or existing or hereafter acquired or arising
          and however and wherever arising or located (the "Collateral"):

                    (a)  Equipment;

                    (b)  Inventory;

                    (c)  Receivables;

                    (d)  General Intangibles;

                    (e)  chattel paper, instruments and documents:  all
          chattel paper, all instruments, including, without limitation,
          all notes evidencing intercompany loans, and all bills of lading,
          warehouse receipts and other documents of title;

                    (f)  other Property:  all Property and interests in
          property of the Grantor which may now be in or may hereafter come
          into the possession, custody or control of the Agent or any
          Secured Party, or any agent or affiliate of the Agent or any
          Secured Party, in any way or for any purpose (whether for
          safekeeping, deposit, custody, pledge, transmission, collection
          or otherwise), and all rights and interests of the Grantor in
          respect of any and all (i) drafts, letters of credit, stocks,
          bonds, and debt and equity securities, whether or not
          certificated, and warrants, options, puts and calls and other
          rights to acquire or otherwise relating to the same, and all
          securities accounts, financial assets and security entitlements,
          (ii) interest rate and currency exchange agreements, including,
          without limitation, cap, collar, floor, forward and similar
          agreements and interest rate protection agreements, (iii) cash
          and Cash Equivalents, and (iv) proceeds of loans, advances and
          other financial accommodations, including, without limitation,
          Loans, advances and other financial accommodations made or
          extended under the Credit Agreement; and all other personal
          Property and interests in personal property of the Grantor not
          specifically included in Sections 1(a) through 1(e) above; and
                                   -------------         ----
                    (g)  all accessions and additions to, substitutions and
          documents for, and replacements, proceeds and products of any of
          the foregoing Collateral, and all payments under insurance
          (whether or not the Agent is the loss payee thereof), and any
          indemnity, warranty or guaranty, payable by reason of loss or
          damage to or otherwise with respect to any of the foregoing
          Collateral, to the extent not otherwise included.

                    SECTION 2.  Security for Obligations.  The Liens and
                                ------------------------
          security interests granted in this Agreement secure the payment
          and performance of all of the obligations of the Grantor under
          the Credit Agreement, including, without limitation, the
          Obligations, and all other liabilities, obligations, covenants
          and duties owing to the Agent and/or any Secured Party from or by
          the Grantor of any kind or nature, present or future, whether or
          not evidenced by any note, guaranty or other instrument, arising
          under or in connection with this Agreement or any of the other
          Loan Documents, whether or not for the payment of money, whether
          direct or indirect (including those acquired by assignment),
          absolute or contingent, due or to become due, now existing or
          hereafter arising, and however acquired (all such obligations of
          the Grantor being the "Secured Obligations").  Without limiting
          the generality of the foregoing, the Liens and security interests
          granted in this Agreement secure the payment of all amounts which
          constitute part of the Secured Obligations and would be owed by
          the Grantor to the Agent and/or any Secured Party but for the
          fact that they are unenforceable or not allowable due to the
          existence of a bankruptcy, reorganization or similar proceeding
          involving the Grantor.

                    SECTION 3.  Grantor Remains Liable.  Anything herein to
                                ----------------------
          the contrary notwithstanding, (a) the Grantor shall remain liable
          under the contracts and agreements included in the Collateral to
          the extent set forth therein to perform all of its duties and
          obligations thereunder to the same extent as if this Agreement
          had not been executed, (b) the exercise by the Agent of any of
          the rights hereunder shall not release the Grantor from any of
          its duties or obligations under the contracts and agreements
          included in the Collateral, and (c) neither the Agent nor any
          Secured Party shall have any obligation or liability under the
          contracts and agreements included in the Collateral by reason of
          this Agreement, nor shall the Agent or any Secured Party be
          obligated to perform any of the obligations or duties of the
          Grantor thereunder or to take any action to collect or enforce
          any claim for payment in which a security interest is granted
          hereunder.

                    SECTION 4.  Representations and Warranties.  The
                                ------------------------------
          Grantor represents and warrants as follows:

                    (a)  All of the Inventory and Equipment is located at
          the places specified on Exhibit A attached hereto and made a part
                                  ---------
          hereof, except for Inventory in transit, provided that Inventory
          and Equipment may be moved to other locations in accordance with
          Section 6(a).  All of the Inventory which is imported from a
          ------------
          location outside the United States arrives at one of the ports or
          other locations identified on Exhibit A.  If any location of
                                        ---------
          Inventory or Equipment is subject to a lease, sublease, mortgage
          or similar instrument, the name and address of each lessor,
          sublessor, lessee, sublessee and/or mortgagee (other than the
          Grantor) is set forth on Exhibit A below the address of such
                                   ---------
          location or on a notice delivered to the Agent pursuant to
          Section 6(a).  The name and address of each bailee, processor,
          ------------
          warehouseman, consignee or other Person in possession of any of
          the Inventory or Equipment (each such Person being a "Bailee") on
          the date hereof, other than carriers and shippers of Inventory in
          transit, is set forth on Exhibit A, together with the address of
                                   ---------
          the location where such Inventory or Equipment is or may be held. 
          Except as otherwise indicated on Exhibit A, no Person (other than
                                           ---------
          a Person identified on Exhibit A as being a consignee) in
                                 ---------
          possession of any of the Inventory or Equipment conducts a
          business at the location of such Inventory or Equipment other
          than a business in the nature of warehousing or transporting
          goods for others.  In the event that any Inventory is in the
          possession of a Bailee, such Inventory shall not be evidenced by
          a negotiable instrument or document.

                    (b)  The principal place of business and chief
          executive office of the Grantor are located at the address first
          specified above for the Grantor or at such other address as the
          Grantor may designate in accordance with Section 7, and all
                                                   ---------
          records concerning the Receivables are located at the addresses
          specified on Exhibit B attached hereto and made a part hereof or
                       ---------
          at such other addresses as the Grantor may designate in
          accordance with Section 7.  The amount represented by the Grantor
                          ---------
          from time to time to the Agent as the amount owing by each
          account debtor or by all account debtors in respect of any
          accounts will, at such time, be the correct amount actually and
          unconditionally owing by such account debtor(s) thereunder to the
          best of the Grantor's knowledge (except to the extent, if any,
          that such account debtor(s) may be entitled to normal trade
          discounts, adjustments, returns and allowances).

                    (c)  The Grantor has good, indefeasible and
          merchantable title to the Collateral.  The Grantor is the legal
          and beneficial owner of the Collateral free and clear of any
          Lien, except for the security interest created by this Agreement
          and Liens permitted under Section 10.3 of the Credit Agreement. 
          Except as identified on Schedule 1.1.4 to the Credit Agreement,
          no financing statement or other instrument similar in effect
          covering all or any part of the Collateral is on file in any
          recording office on the date hereof, except such as may have been
          filed in favor of the Agent relating to this Agreement.

                    (d)  The correct corporate name of the Grantor on the
          date hereof is AMERICAN ECO FUNDING CORP. and, except as set
          forth on Exhibit C attached hereto and made a part hereof, the
                   ---------
          Grantor has no other corporate or fictitious name and has not,
          during the immediately preceding five (5) years, been known by or
          used any other corporate or fictitious name.  The Grantor will
          not change its name, identity or structure in any manner unless
          the Grantor shall have given the Agent at least sixty (60) days'
          prior written notice thereof.

                    (e)  This Agreement, together with the filing of the
          financing statements listed on Exhibit D attached hereto and made
                                         ---------
          a part hereof, upon the giving of value to the Grantor by the
          Secured Parties, creates a valid and perfected first priority
          security interest in the Collateral, securing the payment of the
          Secured Obligations, and all such filings and other actions which
          the Agent has informed the Grantor are necessary or desirable to
          perfect and protect such security interest have been duly made or
          taken.

                    (f)  No consent of any other Person and no
          authorization, approval or other action by, and no notice to or
          filing with, any Governmental Authority is required (i) for the
          grant by the Grantor of the security interest granted hereby or
          for the execution, delivery or performance of this Agreement by
          the Grantor or, (ii) for the perfection (except for filings
          required to perfect a security interest in Collateral) or, except
          for the filing of the appropriate continuation statements with
          respect to the financing statements listed on Exhibit D,
                                                        ---------
          maintenance of the security interest created hereby (including
          the maintenance of the first priority nature of such security
          interest) or (iii) for the exercise by the Agent of its rights
          and remedies hereunder.

                    (g)  There are no conditions precedent to the
          effectiveness of this Agreement that have not been satisfied or
          waived in writing.

                    SECTION 5.  Further Assurances.
                                ------------------

                    (a)  The Grantor agrees that from time to time, at the
          expense of the Grantor, the Grantor will promptly execute and
          deliver all further instruments and documents, and take all
          further action which may be necessary or desirable in the opinion
          of the Agent or its counsel, or that the Agent may reasonably
          request, in order to perfect and protect any security interest
          granted or purported to be granted hereby and enable the Agent to
          exercise and enforce its rights and remedies hereunder with
          respect to any Collateral, and the Grantor shall in any event
          take such action as may be required to maintain the truthfulness
          and accuracy of the representations and warranties contained in
          Section 4.  Without limiting the generality of the foregoing: (i)
          ---------
          in the event that the Grantor has accounts with respect to which
          the account debtor is the United States of America or any
          department, agency or instrumentality thereof (all such accounts
          being hereinafter referred to as "Government Receivables"), the
          Grantor shall, at the request of the Agent, with respect to such
          Government Receivables, promptly comply with the Assignment of
          Claims Act of 1940, as amended (31 U.S.C. Section 3727 et seq.), 
                                                                 -- ---
          and shall promptly deliver to the Agent evidence of such compliance,
          which evidence shall be in form and substance satisfactory to the
          Agent in its sole discretion; (ii) the Grantor shall execute and
          file such financing and continuation statements, and amendments
          thereto, and such other instruments or notices, as may be
          necessary or desirable, or as the Agent may request, in order to
          perfect and preserve the security interest granted or purported
          to be granted hereby; and (iii) the Grantor shall obtain and
          deliver to the Agent notices, agreements (including, without
          limitation, subordination agreements) and other documents
          reasonably requested by the Agent for the purpose of giving
          advice of and perfecting the Liens granted to the Agent for its
          benefit and the ratable benefit of the Secured Parties and
          establishing the senior priority of the Agent's security interest
          over such other parties' rights and interests in respect of
          Equipment, Inventory or other Collateral held in the possession
          of, Bailees, lessors, mortgagees or other third parties, and
          shall use its best efforts to cause such third parties to
          acknowledge or consent to such notices, agreements and other
          documents.

                    (b)  The Grantor hereby authorizes the Agent to file
          one or more financing and continuation statements, and amendments
          thereto, relating to all or any part of the Collateral without
          the signature of the Grantor where permitted by law.  The Grantor
          hereby agrees that a photocopy or other reproduction of this
          Agreement or any financing statement covering the Collateral or
          any part thereof shall be sufficient as a financing statement
          where permitted by law.

                    SECTION 6.  Covenants Regarding Equipment and
                                ---------------------------------
          Inventory.
          ---------

                    (a)  The Grantor shall keep the Equipment and
          Inventory, except for Inventory in transit, at the locations
          specified on Exhibit A or, upon thirty (30) days' prior written
                       ---------
          notice to the Agent, at such other places in jurisdictions where
          all actions required by Section 5 shall have been taken with
                                  ---------
          respect to the Equipment and Inventory.

                    (b)  If any Equipment or Inventory is in the possession
          or control of any Bailee or any of the Grantor's agents, the
          Grantor shall notify such Bailee or agent of the Agent's security
          interest in such Equipment or Inventory and, upon the Agent's
          request following the occurrence of an Event of Default, direct
          such Bailee or agent to hold all such Equipment or Inventory for
          the Agent's account and subject to the Agent's instructions.

                    SECTION 7.  Covenants Regarding Receivables.  The
                                -------------------------------
          Grantor shall keep its chief place of business and chief
          executive office and the office where it keeps its records
          concerning the Receivables at the location(s) specified on
          Exhibit B or, upon thirty (30) days' prior written notice to the
          ---------
          Agent, at any other locations in a jurisdiction where all actions
          required by Section 5 shall have been taken with respect to the
                      ---------
          Receivables.

                    SECTION 8.  Appointed Attorney-in-Fact.  The Grantor
                                --------------------------
          hereby irrevocably appoints the Agent the Grantor's
          attorney-in-fact, with full authority in the place and stead of
          the Grantor and in the name of the Grantor or otherwise, from
          time to time in the Agent's discretion, to take any action and to
          execute any instrument which the Agent may deem necessary or
          advisable to accomplish the purposes of this Agreement,
          including, without limitation, following the occurrence of an
          Event of Default:

          due and to become due under or in connection with any of the
          Collateral;

                    (b)  to receive, indorse, and collect any drafts or
          other instruments, documents and chattel paper, in connection
          with clause (a) above; 
               ---------

                    (c)  to file any claims or take any action or institute
          any proceedings which the Agent may deem necessary or desirable

          Collateral; and

                    (d)  to receive, open and dispose of all mail addressed
          to the Grantor.

          The Grantor hereby ratifies all that such attorney-in-fact shall
          lawfully do or cause to be done by virtue hereof.  This power of
          attorney is coupled with an interest and shall be irrevocable.

                    SECTION 9.  Agent May Perform.  If the Grantor fails to
                                -----------------
          perform any agreement contained herein, the Agent may itself
          perform, or cause performance of, such agreement, and the
          expenses of the Agent incurred in connection therewith shall be
          payable by the Grantor to the Agent upon demand by the Agent. 

                    SECTION 10.  The Agent's Rights and Duties.  The powers
                                 -----------------------------
          conferred on the Agent and the Secured Parties hereunder are
          solely to protect their interest in the Collateral and shall not
          impose any duty upon any of them to exercise any such powers. 
          Except for the safe custody of any Collateral in its possession
          and the accounting for moneys actually received by it hereunder,
          the Agent shall have no duty as to any Collateral.  Any action
          taken or omitted to be taken by the Agent in connection with any
          of the Collateral shall not result in any liability of the Agent
          to the Grantor unless such action or omission shall be determined
          by a court of competent jurisdiction to have arisen out of the
          gross negligence or willful misconduct of the Agent.  The Agent
          may exercise any of its rights and execute any of its duties
          hereunder by or through agents or employees and shall be entitled
          to advice of counsel concerning all matters pertaining to its
          rights and duties hereunder.

                    SECTION 11.  Remedies.  If any Event of Default shall
                                 --------
          have occurred and be continuing:

                    (a)  The Agent may exercise in respect of the
          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 upon default under the Uniform Commercial Code
          in effect in the State of New York at that time (the "Uniform
          Commercial Code") (whether or not the Uniform Commercial Code
          applies to the affected Collateral), and also may (i) without
          notice, demand or legal process of any kind, all of which the
          Grantor hereby waives to the extent permitted by applicable law,
          at any time or times enter the Grantor's premises and take
          physical possession of the Collateral and maintain such
          possession on the Grantor's premises, at no cost to the Agent, or
          remove the Collateral or any part thereof, to such other places
          as the Agent may desire, (ii) require the Grantor to, and the
          Grantor hereby agrees that it will at its own expense and upon
          request of the Agent forthwith, assemble all or part of the
          Collateral as directed by the Agent and make it available to the
          Agent at a place to be designated by the Agent which is
          reasonably convenient to both parties, and (iii) without notice,
          except as specified below, sell, lease, assign, grant an option
          or options to purchase or otherwise dispose of the Collateral or
          any part thereof in one or more parcels at public or private
          sale, at any of the Agent's offices or elsewhere, for cash, on
          credit or for future delivery, and upon such other terms as the
          Agent may deem commercially reasonable.  The Grantor agrees that,
          to the extent notice of sale shall be required by law, at least
          five (5) business days' notice to the Grantor of the time and
          place of any public sale or the time after which any private sale
          is to be made shall constitute commercially reasonable
          notification.  The Agent shall not be obligated to make any sale
          of Collateral regardless of notice of sale having been given. 
          The Agent 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.  The Agent is hereby granted
          a license or other right to use, without charge, the Grantor's
          trademarks, registered trademarks, trademark applications,
          service marks, registered service marks, service mark
          applications, patents, patent applications, trade names, rights
          of use of any name, labels, fictitious names, inventions,
          designs, trade secrets, computer programs, software, printouts
          and other computer materials, goodwill, registrations,
          copyrights, copyright applications, permits, licenses,
          franchises, customer lists, credit files, correspondence, and
          advertising materials, or any Property of a similar nature, as it
          pertains to the Collateral, or any rights to any of the
          foregoing, in completing production of, advertising for sale, and
          selling any Collateral, and the Grantor's rights under all
          licenses and franchise agreements shall inure to the Agent's
          benefit.

                    (b)  IF AN EVENT OF DEFAULT OCCURS, THE GRANTOR HEREBY
          IRREVOCABLY WAIVES ALL RIGHTS TO NOTICE AND HEARING OF ANY KIND
          PRIOR TO THE EXERCISE BY THE AGENT OF ITS RIGHTS TO REPOSSESS THE
          COLLATERAL WITHOUT JUDICIAL PROCESS OR TO REPLEVY, ATTACH OR LEVY
          UPON SUCH COLLATERAL WITHOUT PRIOR NOTICE OR HEARING.

                    (c)  Any cash held by the Agent as Collateral and all
          cash proceeds received by the Agent in respect of any sale of,
          collection from, or other realization upon all or any part of the
          Collateral may, in the discretion of the Agent, be held by the
          Agent as Cash Collateral for, and/or then or at any time
          thereafter be applied in whole or in part by the Agent for its
          benefit and for the ratable benefit of the Secured Parties
          against, all or any part of the Secured Obligations in such order
          as the Agent shall elect, subject to any provision of the Credit
          Agreement governing the application of such cash, proceeds, or
          other realization upon the Collateral.

                    (d)  The Agent shall have the right, upon notice to the
          Grantor of its intention to do so, to notify the account debtors
          or obligors under any Receivables of the assignment of such
          Receivables to the Agent and to direct such account debtors or
          obligors to make payment of all amounts due or to become due to
          the Grantor thereunder directly to the Agent and, upon such
          notification and at the expense of the Grantor, to enforce
          collection of any such Receivables, and to adjust, settle or
          compromise the amount or payment thereof, in the same manner and
          to the same extent as the Grantor might have done.  After receipt
          by the Grantor of the notice from the Agent referred to in the
          preceding sentence, (i) all amounts and proceeds (including
          instruments) received by the Grantor in respect of the
          Receivables shall be received in trust for the benefit of the
          Agent hereunder, shall be segregated from other funds of the
          Grantor and shall be forthwith paid over to the Agent in the same
          form as so received (with any necessary indorsement) to be held
          as Cash Collateral and shall be applied as provided by Section
                                                                 -------
          11(c) above, and (ii) the Grantor shall not adjust, settle or
          ----
          compromise the amount or payment of any Receivable, release
          wholly or partly any account debtor or obligor thereof, or allow
          any credit or discount thereon.  In any suit, proceeding or
          action brought by the Agent under any account comprising part of
          the Collateral, the Grantor will save, indemnify and keep the
          Agent and each Secured Party harmless from and against all
          expense, loss or damages suffered by reason of any defense,
          setoff, counterclaim, recoupment or reduction of liability
          whatsoever of the obligor thereunder, arising out of a breach by
          the Grantor of any obligation or arising out of any other
          agreement, Indebtedness or liability at any time owing to or in
          favor of such obligor or its successors from the Grantor, and all
          such obligations of the Grantor shall be and shall remain
          enforceable against and only against the Grantor and shall not be
          enforceable against the Agent or any Secured Party.

                    SECTION 12.  Amendments, Etc.  No amendment or waiver
                                 ---------------
          of any provision of this Agreement, and no consent to any
          departure by the Grantor herefrom, shall in any event be
          effective unless the same shall be in writing and signed by the
          Agent, and then such waiver or consent shall be effective only in
          the specific instance and for the specific purpose for which
          given.

                    SECTION 13.  Notices, Etc.  All notices and other
                                 ------------
          communications provided for hereunder shall be given in the
          manner and to the addresses set forth in the Credit Agreement,
          except that any notice provided by the Grantor to the Agent
          hereunder shall be effective only upon receipt thereof by the
          Agent.

                    SECTION 14.  Continuing Security Interest; Assignments
                                 -----------------------------------------
          under Credit Agreement; Termination; Payments Set Aside.  This
          -------------------------------------------------------
          Agreement shall create a continuing security interest in the
          Collateral and shall (i) remain in full force and effect until
          payment in full in cash of the Secured Obligations and
          termination of the Credit Agreement, (ii) be binding upon the
          Grantor, its successors and assigns, and (iii) inure to the
          benefit of, and be enforceable by, the Agent, the Secured Parties
          and their respective successors, and permitted transferees and
          assigns.  Without limiting the generality of the foregoing clause
                                                                     ------
          (iii), any Secured Party may assign or otherwise transfer all or
          ----
          any portion of its rights and obligations under the Credit
          Agreement in accordance with the terms thereof (including,
          without limitation, all or any portion of its Commitments and any
          Loans or Reimbursement Obligations owing to it) to any other
          Person, and such other Person shall thereupon become vested with
          all the benefits in respect thereof granted to such Secured Party
          herein or otherwise.  Upon the payment in full in cash of the
          Secured Obligations and the termination of the Credit Agreement,
          the security interest granted hereby shall terminate and all
          rights to the Collateral shall revert to the Grantor.  To the
          extent that the Grantor makes a payment or payments to the Agent
          or any Secured Party, or the Agent or the Secured Parties enforce
          their security interests or exercise their rights of set-off, and
          such payment or payments or the proceeds of such enforcement or
          set-off or any part thereof are subsequently invalidated,
          declared to be fraudulent or preferential, set aside and/or
          required to be repaid to a trustee, receiver or any other party
          under any bankruptcy law, state or federal law, common law or
          equitable cause, then, to the extent of such recovery, the
          obligation or part thereof originally intended to be satisfied,
          and all Liens, rights and remedies therefor, shall be revived and
          continued in full force and effect as if such payment had not
          been made or such enforcement or set-off had not occurred.

                    SECTION 15.  Survival of Representations and
                                 -------------------------------
          Warranties.  The Grantor covenants, warrants, and represents to
          ----------
          the Agent and the Secured Parties that all representations and
          warranties of the Grantor contained in this Agreement shall be
          true at the time of the Grantor's execution of this Agreement,
          shall survive the execution, delivery and acceptance hereof by
          the parties hereto and the closing of the transactions described
          in the Credit Agreement and the other Loan Documents and shall
          continue in effect until all of the Secured Obligations shall
          have been paid in full in cash and the Credit Agreement has been
          terminated.

                    SECTION 16.  Governing Law; Terms; Severability.  This
                                 ----------------------------------
          Agreement shall be governed by, and construed in accordance with,
          the laws of the State of New York (without reference to choice-
          of-law principles), except as required by mandatory provisions of
          law and except to the extent that the validity or perfection of
          the security interest hereunder, or any of the remedies
          hereunder, in respect of any particular Collateral, may be
          governed by the laws of a jurisdiction other than the State of
          New York.  Unless otherwise defined herein or in the Credit
          Agreement, terms used in Article 9 of the Uniform Commercial Code
          are used herein as therein defined.  If any provision of this
          Agreement shall be prohibited by or invalid under applicable law,
          such provision shall be ineffective to the extent of such
          prohibition or invalidity, without invalidating the remainder of
          such provision or the remaining provisions of this Agreement.

                    SECTION 17.  No Waiver; Remedies.  No failure on the
                                 -------------------
          part of any Secured Party or the Agent to exercise, and no delay
          in exercising, any right hereunder shall operate as a waiver
          thereof; nor shall any single or partial exercise of any right
          hereunder preclude any other or further exercise thereof or the
          exercise of any other right.  The remedies herein provided are
          cumulative and not exclusive of any remedies provided by law.

                    SECTION 18.  Marshalling; Recourse to Security.  None
                                 ---------------------------------
          of the Secured Parties or the Agent shall be under any obligation
          to marshall any assets in favor of the Grantor or any other party
          or against or in payment of any or all of the Secured
          Obligations.  Recourse to security shall not be required at any
          time.  

                    SECTION 19.  Construction.
                                 ------------

                    (a)  The parties acknowledge that each party and its
          counsel have reviewed and revised this Agreement and that the
          normal rule of construction to the effect that any ambiguities
          are to be resolved against the drafting party shall not be
          employed in the interpretation of this Agreement or any
          amendments or exhibits hereto.

                    (b)  The words "hereof", "herein" and "hereunder" and
          words of like import when used in this Agreement shall refer to
          this Agreement as a whole and not to any particular provision of
          this Agreement and section references are to this Agreement
          unless otherwise specified.

                    (c)  All terms defined in this Agreement in the
          singular shall have comparable meanings when used in the plural,
          and vice versa, unless otherwise specified.
              ---- -----

                    SECTION 20.  Headings.  Section headings in this
                                 --------
          Agreement are included herein for convenience of reference only
          and shall not constitute a part of this Agreement for any other
          purpose. 

                    SECTION 21.  Execution in Counterparts.  This Agreement
                                 -------------------------
          and any amendments, waivers, consents, or supplements hereto may
          be executed in any number of counterparts and by different
          parties hereto in separate counterparts, each of which when so
          executed shall be deemed to be an original and all of which taken
          together shall constitute one and the same agreement.

                    IN WITNESS WHEREOF, the parties hereto have caused this
          Agreement to be executed by their respective officers thereunto
          duly authorized, as of the date first above written.
