          THIS LEASE GUARANTY, dated as of May 30, 1986, by MATERIAL SCIENCES
CORPORATION ("MSC"), a Delaware corporation, to CORPORATE PROPERTY ASSOCIATES, a
California limited partnership, and CORPORATE PROPERTY ASSOCIATES 2, a
California limited partnership, jointly and severally as tenants-in-common
(hereinafter jointly and severally referred to as "Lessor"), and to
CREDITANSTALT-BANKVEREIN (New York Branch) (hereinafter, "Lender"), as their
respective interests may appear.

                              W I T N E S S E T H:

          WHEREAS, MSC is the owner of all of the issued and outstanding common
stock of PRE FINISH METALS INCORPORATED, an Illinois corporation ("PFM");

          WHEREAS, PFM has entered into a Lease and Agreement, dated as of
December 1, 1980 with Lessor's predecessor in interest, Line 6 Corp. (the
"12/1/80 Lease"), which has been amended by a First Amendment To Lease and
Agreement, dated as of the date hereof (the "Lease Amendment"), between Lessor
and PFM (the 12/1/80 Lease as so amended by such Lease Amendment, being
hereinafter called the "Lease"), relating to the leasing of the Premises
referred to in the Lease;

          WHEREAS, Lessor has requested Lender to make a mortgage loan to Lessor
in order to refinance certain existing indebtedness covering a portion of the
Premises and to provide funds for the acquisition of another portion of the
Premises (such loan being hereinafter referred to as the "Loan");

          NOW, THEREFORE, in order to induce Lessor to enter into the Lease
Amendment and Lender to make the Loan, and in consideration of the premises, the
parties

                                       1


hereto agree as follows (each defined term used in this Agreement has the
meaning therefor set forth in the Agreement, or, if not so set forth, the
meaning therefor set forth in the Lease):

          SECTION 1.     Guaranty.
                         --------

          1.1. Guaranty of Payment and Performance. (a) MSC hereby
               -----------------------------------
unconditionally guarantees to Lessor the due and punctual payment of all sums
stated in Lease to be payable by PFM ("Rent"), when and as the same shall become
due and payable during or after the expiration or earlier termination of the
Term. Such guaranty is an absolute, unconditional, present and continuing
irrevocable guaranty of payment and not of collectibility and is in no way
conditioned or contingent upon any attempt to collect from PFM, any attempt to
realize upon any or all security existing at any time for the benefit of Lessor
or upon any other condition or contingency. If PFM shall fail to pay punctually
any Rent when and as the same shall become due and payable, MSC will immediately
pay the same to Lessor or to any other person to whom the same is due and
payable. Should Lessor or Lender be obligated by any bankruptcy or other law to
repay to PFM or MSC or to any trustee, receiver or other representative of
either of them, any amounts previously paid, then this Agreement shall be
reinstated in the amounts of such repayment. Neither Lessor nor Lender shall be
required to litigate or otherwise dispute its obligation to make such repayments
if it in good faith and on the advice of counsel believes that such obligation
exists.

          (b)  MSC unconditionally guarantees that PFM will duly perform and
comply with all of the terms of the Lease which are required to be performed or
complied with by PFM. In case PFM shall fail so to perform or comply with any
such term, whether or not such failure shall constitute a Default or an Event of
Default, MSC, upon receipt of notice of such failure

                                       2


(regardless of the source of such notice), will promptly perform or comply with
such term or cause the same to be performed or complied therewith.

          1.2  MSC's Obligations Absolute.  The obligations of MSC under this
               --------------------------
Agreement are absolute, unconditional, present and continuing and irrevocable,
are not subject to any counterclaim, set-off, deduction or defense based upon
any claim MSC may have against PFM or Lessor or Lender and shall remain in full
force and effect without regard to, and shall not be impaired or affected,
except to the extent otherwise specifically agreed by Lessor and Lender, by:

          (a) any extension or indulgence in respect of the payment of Rent or
any part thereof, or any prepayment of any part; or

          (b) any renewal, extension, amendment or modification of or addition
or supplement to or deletion from any of the terms of the Lease, or any other
agreement which may be made relating to the Lease; or

          (c) any waiver, indulgence, compromise, release or consent or other
action or inaction in respect of any of the terms of the Lease; or

          (d) any exercise or non-exercise by Lessor of any right, power or
remedy under or in respect of the Lease; or any waiver of any such right, power
or remedy or of any default in respect of the Lease; or any amendment, whether
or not material, to the Lease; or

          (e) any bankruptcy, insolvency, reorganization, arrangement,
adjustment, composition, or liquidation of PFM; or

                                  3



          (f) any limitation of the liability of PFM under the Lease which may
now or hereafter be imposed by any statute, regulation or rule of law, or any
invalidity, illegality, lack of binding effect or unenforceability, in whole or
in part, of the Lease or any term thereof; or

          (g) any merger or consolidation of PFM into or with any other Person,
or any sale, lease or transfer of any or all of the assets of PFM to any other
Person; or

          (h) any defect in the title of PFM to any of its property or the
failure of the Lessor to record properly the Lease or to file properly any
financing statement with respect thereto; or

          (i) absence of any notice to, or knowledge by, MSC of the existence or
occurrence of any of the matters or events set forth in the foregoing paragraphs
(a) through (h); or

          (j) any other circumstance similar or dissimilar to any of the
foregoing which might now or hereafter constitute a legal or equitable discharge
or defense of a guarantor, other than payment and performance in full of all of
the obligations of PFM under the Lease.

          1.3  Waiver.  MSC unconditionally waives (a) notice of any of the
               ------
matters referred to in Section 1.2, (b) all notices which may be required by
statute, rule of law or otherwise, to preserve intact any rights of Lessor or
Lender against MSC, including, without limitation, any demand, presentment and
protest, notice of acceptance, proof of notice of non-payment under the Lease,
and notice of any failure on the part of PFM to perform and comply with any
covenant, agreement, term or condition of the Lease, (c) any right to the
enforcement, assertion or exercise by Lessor or Lender of any right, power or
remedy conferred in the Lease or otherwise, (d) any requirement of diligence on
the part of Lessor or Lender, and (e) any

                                       4


requirement on the part of Lessor or Lender to mitigate the damages resulting
from default under the Lease.

          1.4  Waiver of Subrogation.  In the event MSC shall at any time pay
               ---------------------
any sums on account of the Rent or take any other action in performance of its
obligations under this Agreement, MSC shall notify Lessor and Lender of such
payment and/or performance and MSC shall have no rights, by way of subrogation
or otherwise, to the rights of Lessor or Lender and MSC hereby waives all such
rights of subrogation and all rights of reimbursement or indemnity whatsoever
and all rights of recourse to any security for the Lease unless and until all of
the payment and performance obligations of PFM which are then due shall have
been paid and performed in full.

          SECTION 2.    Representations and Warranties. MSC represents and
                        ------------------------------
warrants to Lessor and Lender as follows:

          2.1  Organization and Standing of MSC.  MSC is a corporation duly
               --------------------------------
organized, validly existing and in good standing under the laws of the State of
Delaware and has all requisite corporate power and authority necessary to own
and operate its properties and to carry on its business as now conducted and
presently proposed to be conducted, to enter into this Agreement, and to carry
out the terms hereof.

          2.2  Subsidiaries.  Each Subsidiary of MSC is duly organized, validly
               ------------
existing and in good standing under the laws of the jurisdiction of its
incorporation and has all requisite corporate power and authority necessary to
own and operate its properties and to carry on its business.  All of the issued
and outstanding shares of capital stock of each Subsidiary of MSC have been duly
and validly issued, are fully paid and non-assessable.  Each of MSC and its

                                       5


Subsidiaries own 100% of the securities of each Subsidiary owned by it, which
securities are free and clear of any mortgage, pledge, lien, security interest,
encumbrance or charge. PFM is a Subsidiary.

          2.3  Qualification.  MSC and its Subsidiaries are duly qualified,
               -------------
licensed at domesticated and in good standing as foreign corporations duly
authorized to do business in all jurisdictions wherein the character of the
properties owned or the nature of the activities conducted makes such
qualification, licensing or domestication necessary and where the failure to so
qualify would have a material adverse effect upon the condition of MSC or of any
of its Subsidiaries.

          2.4  Financial Statements.  MSC has furnished Lessor and Lender with
               --------------------
complete and correct copies of consolidated balance sheets of MSC and its
Subsidiaries as at its fiscal year end in each of the years 1985 and 1984,
inclusive, and the related statements of income, stockholders, investments and
changes in financial position for the fiscal years then ended, accompanied by
the reports thereon of Arthur Andersen & Co., independent public accountants.
Such financial statements have been prepared in accordance with generally
accepted accounting principles, reflect all known liabilities of such
corporations, including all contingent liabilities, and present fairly the
financial position of such corporations as at such dates and the results of
their operations for the periods indicated, in conformity with generally
accepted accounting principles consistently applied.  It is the intent of this
Agreement that unless the context hereof shall clearly express a contrary intent
the financial statements or financial conditions referred to herein mean the
consolidated financial statement or financial conditions of

                                       6


MSC and its Subsidiaries determined in a manner consistent with the financial
statements referred to hereinabove.

          2.5  Changes. Since February 28, 1996, there has been no change in the
               -------
assets, liabilities or financial condition of MSC and its Subsidiaries other
than changes contemplated hereby and changes in the ordinary course of business
which have not been, either in any case or in the aggregate, material and
adverse, and neither the financial condition, business or operations of MSC and
its Subsidiaries nor any of their respective properties or assets have been
materially and adversely affected by any occurrence or development, whether or
not insured against. It is agreed and understood that changes since February 28,
1986 shown on Exhibit A hereto shall be deemed to be in the ordinary course of
business and not be deemed materially adverse.

          2.6  Title to Properties; Liens.  MSC and its subsidiaries have good
               --------------------------
and sufficient title to their respective properties and assets, including those
shown on the balance sheet as at February 28, 1986, referred to in Section 2.4,
and those acquired since such date (except properties and assets disposed of
since such date in the ordinary course of business or for fair consideration),
subject to no mortgage, pledge, lien, security interest, lease, encumbrance or
charge except those disclosed in footnotes to MSC's financial statements or
contemplated by this Agreement.  MSC and its Subsidiaries possess all patents,
patent rights or licenses, trademarks, trademark rights, trade names, trade name
rights, and copyrights which are required to conduct their respective businesses
as now conducted or as proposed to be conducted without known conflict with the
rights of others.  None of the properties or assets the value of which is
reflected in such balance sheet is held by MSC or any Subsidiary as lessee under
any lease (other than

                                       7


capitalized lease obligations) or as conditional vendee under any conditional
sale or other title retention agreement.

          2.7  Tax Returns and Payments.  All tax returns and reports of MSC
               ------------------------
and its Subsidiaries required by law to be filed through the date hereof have
been duly filed, and all taxes, assessments, fees and other governmental charges
upon MSC and its Subsidiaries or upon any of their properties, assets, income or
franchises which are due and payable have been paid, other than those presently
payable without penalty or interest, together with those whose payment is being
legally contested by MSC or its Subsidiaries, the amounts of which, either in
any case or in the aggregate, do not materially and adversely affect the
business, operation, affairs or condition (financial or otherwise) of MSC and
its Subsidiaries or any of their respective properties or assets.  All such tax
returns were prepared in accordance with standards customarily used in preparing
similar returns by persons engaged in businesses similar to those of MSC and its
Subsidiaries and all such returns were prepared in a proper manner in accordance
with applicable law and regulations.  MSC and its Subsidiaries have provided
adequate reserves for the payment of all Federal and state income taxes the
payment of which is not yet due.  There is no unpaid assessment for Federal
income tax liability of MSC and its Subsidiaries for any period. The Federal
income tax liability of MSC and its Subsidiaries has been finally determined
through the fiscal year ended February 28, 1982.

          2.8  Litigation.  There is no action, suit, proceeding or
               ----------
investigation pending or, to the best knowledge of MSC, threatened (or any basis
therefor) which either in any case or in the aggregate might result in any
material adverse change in the financial conditions, business or operations of
MSC and its Subsidiaries or in any of their respective properties or assets, or
in

                                       8


any material impairment of the right or ability of MSC or any of its
Subsidiaries to carry and their respective businesses substantially as now
conducted and as presently proposed to be conducted, or in any material
liability (whether or not covered by insurance) an the part of MSC or any of its
Subsidiaries to carry on their respective businesses substantially as now
conducted and as presently proposed to be conducted, or in any material
liability (whether or not covered by insurance) on the part of MSC or any of its
Subsidiaries, or which questions the validity of this Agreement or of any action
taken or to be taken in connection with the transactions contemplated hereby.

          2.9  Compliance with Other Instruments.  Neither MSC nor any of its
               ---------------------------------
Subsidiaries is a party to, bound by, or subject to or in violation of any deed,
franchise, indenture, lease, mortgage, security agreement, permit, pledge,
contract or agreement of any nature whatsoever or, to the best of MSC's
knowledge after due inquiry having been made, any license or instrument, or
subject to any corporate restriction or to any order, rule, regulation, writ,
injunction or decree of any court or governmental authority or to any statute
which or which may in the future (so far as MSC can presently reasonably
foresee) materially and adversely affect the business, operations, financial
condition, properties or assets of MSC or any Subsidiary. Neither the execution,
delivery or performance of this Agreement nor compliance herewith (a) conflicts
or will conflict with or results or will result in a breach of or constitutes or
will constitute a default under (i) the charter documents or by-laws of MSC or
any Subsidiary, (ii) any law or any order, rule, regulation, writ, injunction or
decree of any court or governmental authority, or (iii) any deed, franchise,
indenture, license, lease, instrument, mortgage, security agreement, permit,
pledge, contract or agreement of any nature whatsoever to which MSC or any
Subsidiary is a

                                       9


party, by which it is bound or to which it is subject or, to the extent of any
such conflict, breach or default, a valid waiver or consent has been obtained or
(b) results or will result in the creation or imposition of any lien, charge or
encumbrance upon any property or assets of MSC or any Subsidiary as a
consequence thereof.

          2.10. (a) Relationship of Vested Benefits to Pension Plan Assets.  The
                    ------------------------------------------------------
present value of all benefits vested under all "employee pension benefit plans",
as such term is defined in Section 3 of the Employment Retirement Income
Security Act of 1974, as amended from time to time ("ERISA"), maintained by MSC
and its Subsidiaries, as from time to time in effect (herein called the "Pension
Plans"), do not exceed the value of the assets of the Pension Plans allocable to
such vested benefits by more than $500,000.

          (b)   Prohibited Transactions.  None of the Pension Plans and no
                -----------------------
trusts created thereunder, and no trustee or administrator thereof, has engaged
in a "prohibited transaction", as such term is defined in Section 4175 of the
Internal Revenue Code of 1954, as amended,. which could subject the Pension
Plans or any of them, any such trust, or any trustee or administrator thereof,
or any party dealing with the Pension Plans or any such trust to the tax or
penalty on prohibited transactions imposed by said Section 4975.

          (c)   Reportable Events.  None of the Pension Plans and none of such
                -----------------
trusts have been terminated. There have been no "reportable events", as that
term is defined in Section 4043 of ERISA, since the effective date of ERISA.

          (d)   Accumulated Funding Deficiency. None of the Pension Plans and no
                ------------------------------
such trusts have incurred any "accumulated funding deficiency", as such term is
defined in Section 302 of ERISA (whether or not waived), since the effective
date of ERISA.

                                      10


          2.11  Governmental Consent.  No consent, approval or authorization of

                ------------
default in respect of any outstanding indebtedness or any instrument or
agreement relating thereto.

          2.13  Disclosure.  None of this Agreement, the financial statements
                ----------
referred to in Section 2.4 or any certificate or written statement furnished to
Lessor or Lender by or on behalf of MSC in connection with the transactions
contemplated hereby contains any untrue statement of a material fact or omits to
state a material fact the omission of which makes the statements contained
herein or therein misleading.  There is no presently known fact which materially
and adversely effect or in the future may (so far as MSC can now foresee)
materially and adversely affect the business, financial condition or operations
of MSC or any of its Subsidiaries or any of their respective properties or
assets which has not been disclosed to Lessor and Lender in writing by or on
behalf of MSC.

                                      11

accepted accounting principles, and will set aside and cause each of its
Subsidiaries to set aside on its books all such proper reserves for each fiscal
year for depreciation, obsolescence and amortization and other purposes as shall
be required by generally accepted accounting principles. MSC will deliver to
Lessor and Lender:

     quarterly fiscal periods of each fiscal year of MSC, and in any event
     within 45 days thereafter, consolidated balance sheets of MSC and its
     Subsidiaries as at the end of such period and consolidated statements of
     income and of surplus of MSC and its Subsidiaries for such period and (in

     in comparative form, the figures for the corresponding period (or periods)
     of the previous fiscal year, all in reasonable detail and certified by the
     principal financial officer of MSC as being complete and as fairly

     of their operations for the period then ended, subject only to changes
     resulting from year-end audit adjustments;

          (b)  as soon as practicable after the end of each fiscal year of MSC,
     and in any event within 90 days thereafter, a consolidated balance sheet of
     MSC and its Subsidiaries as at the end of such year and a consolidated
     statement of income and of surplus of MSC and its Subsidiaries for such
     year, setting forth in each case in comparative form the figures for the
     previous fiscal year, all in reasonable detail and accompanied by, in

in consideration thereof and as a further inducement to Lender to make and enter
into the Loan and in consideration thereof, MSC hereby waives trial by jury and
the right thereto in any action or proceeding of any kind or nature, arising on,
