               SIXTH AMENDMENT TO FINANCING AND SECURITY AGREEMENT

      THIS SIXTH AMENDMENT TO FINANCING AND SECURITY AGREEMENT (this
"Agreement") is made as of November 12, 2001, by GLASSTECH, INC., a corporation
organized under the laws of Delaware (the "Borrower"), and UPS CAPITAL
CORPORATION, a Delaware corporation ("Lender"), as successor-in-interest to BANK
OF AMERICA, N.A., a national banking association, formerly "NationsBank, N.A."
("BofA").

                                    RECITALS

      A.    The Borrower and BofA entered into a Financing and Security
Agreement dated July 2, 1997 (the same, as amended, modified, substituted,
extended and renewed from time to time, the "Financing Agreement"). Effective as
of August 31, 2001, Lender assumed from BofA all of its right, title and
interest in, to and under the Financing Agreement. The Financing Agreement
provides for agreements between the Borrower and the Lender with respect to the
"Loans" (as defined in the Financing Agreement).

      B.    The Borrower has requested that the Lender amend certain financial
covenants contained in the Financing Agreement.

      C.    The Lender is willing to agree to the Borrower's request on the
condition that this Agreement be executed.

                                   AGREEMENTS

      NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, receipt of which is hereby acknowledged, the Borrower
and the Lender agree as follows:

      1. The Borrower and the Lender agree that the Recitals above are a part of
this Agreement. Unless otherwise expressly defined in this Agreement, terms
defined in the Financing Agreement shall have the same meaning under this
Agreement.

      2. The Borrower represents and warrants to the Lender as follows:

            (a) The Borrower is a corporation duly organized, and validly
existing and in good standing under the laws of the state in which it was
organized and is duly qualified to do business as a foreign corporation in good
standing in every other state wherein the conduct of its business or the
ownership of its property requires such qualification and in which the failure
to qualify would materially adversely affect the business, operations or
properties of the Borrower and/or its Subsidiaries.

            (b) The Borrower has the power and authority to execute and deliver
this Agreement and perform its obligations hereunder and has taken all necessary
and appropriate corporate action to authorize the execution, delivery and
performance of this Agreement.

            (c) The Financing Agreement, as amended by this Agreement, and each
of the other Financing Documents remains in full force and effect, and each
constitutes the valid and legally binding obligation of the Borrower,
enforceable in accordance with its terms, subject to bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting the
rights and remedies of creditors and secured parties, and general principles of
equity regardless of whether applied in a proceeding in equity or at law.


                                       15

            (d) After giving effect to this Agreement, all of the Borrower's
representations and warranties contained in the Financing Agreement are true and
correct on and as of the date of the Borrower's execution of this Agreement,
except that the representations and warranties which relate to financial
statements which are referred to in Section 4.1.11 of the Financing Agreement,
shall also be deemed to cover financial statements furnished from time to time
to the Lender pursuant to Section 6.1.1 (Financial Statements) of the Financing
Agreement.

            (e) After giving effect to this Agreement, no Event of Default and
no event which, with notice, lapse of time or both would constitute an Event of
Default, has occurred and is continuing under the Financing Agreement or the
other Financing Documents.

            (f) No right of setoff, defense, counterclaim, cross-claim or
recoupment claim exists in favor of the Borrower in respect of its obligations
under the Financing Agreement.

      3. The Borrower acknowledges, consents to and agrees to be bound by the
assignment of BofA to Lender of its right, title and interest as "Lender" under
the Financing Agreement and in respect of the Obligations, effective as of
August 31, 2001, and further agrees, in connection therewith, (a) to attorn to
Lender as "Lender" under the Financing Agreement effective as of and from such
assignment date, and (b) that Lender shall be released from, and shall have no
liability to the Borrower for, any action (or inaction) taken (or omitted) by
BofA as "Lender" in respect of Borrower or pursuant to the Financing Agreement
prior to such assignment becoming effective.

      4. Section 6.1.15 ("Financial Covenants") shall be amended by deleting in
its entirety, the paragraph immediately following the end of existing subsection
(a) thereof ("Fixed Charge Coverage Ratio"), added pursuant to the fifth
amendment to the Financing Agreement, and substituting in its place, the
following paragraph, effective retroactive to June 29, 2001:

      Notwithstanding the foregoing, in respect of (i) the fiscal quarter of the
      Borrower ending on June 30, 2001 and (ii) the fiscal quarter of the
      Borrower ending on September 30, 2001(and only for such fiscal quarters),
      compliance by Borrower with the financial covenant set forth in the
      aforesaid subsection (a) shall be waived if, but only if, the Borrowing
      Base, as then most recently reported, exceeds the aggregate principal
      amount of the Revolving Loan and Outstanding Letter of Credit Obligations
      on such fiscal quarter end date by at least $1,000,000. In addition to the
      foregoing, in respect of (i) the fiscal quarter of Borrower ending on
      September 30, 2001 and (ii) the fiscal quarter of the Borrower ending on
      December 31, 2001(and only for such fiscal quarters), notwithstanding
      anything contained in this Agreement to the contrary, until the date on
      which Borrower is required to submit a Compliance Certificate with respect
      to the quarterly period ending on December 31, 2001, under Section 6.1(c)
      of this Agreement (the "Report Date"), Borrower may disregard its
      compliance, or lack thereof, with the financial covenant set forth in
      subsection (a) above, to the extent that any such non-compliance or the
      failure to report the same, would constitute a Default, Event of Default
      or breach of any of Borrower's obligations under this Agreement,
      including, without limitation for purposes of (i) any Loan Notice,
      Borrowing Base Report or other written submission of Borrower to Lender,
      (ii) any requests by Borrower of Lender pursuant to this Agreement,
      including, without limitation, any requests for the advance of funds or
      for selection of an interest rate (as contemplated by Section 2.3.2) or
      otherwise, or (iii) any representation, warranty or covenant contained in
      the Financing Agreement, provided, however, that Borrower shall be
      required to comply with such financial covenant on the Report Date.


                                       16

      7. This Agreement may be executed in any number of duplicate originals or
counterparts, each of such duplicate originals or counterparts shall be deemed
to be an original and taken together shall constitute but one and the same
instrument. The parties agree that their respective signatures may be delivered
