                          SUBSIDIARY GUARANTY AGREEMENT

      THIS SUBSIDIARY GUARANTY AGREEMENT (as amended, revised, modified,
supplemented or amended and restated from time to time, this "Guaranty") is
entered into as of June 24, 2004 by EACH OF THE UNDERSIGNED AND EACH OTHER
PERSON WHO SHALL BECOME A PARTY HERETO BY EXECUTION OF A GUARANTY JOINDER
AGREEMENT (each, a "Guarantor" and, collectively, the "Guarantors"), in favor of
BANK OF AMERICA, N.A., in its capacity as administrative agent for the Lenders
(as hereinafter defined), and the GUARANTEED CREDITORS (as defined on Exhibit B
attached hereto). All capitalized terms used but not otherwise defined herein
shall have the meaning ascribed to such term by the Credit Agreement (as defined
below).

                                   WITNESSETH:

      WHEREAS, Libbey Glass Inc., a Delaware corporation (the "US Borrower"),
Libbey Europe B.V., a company organized and existing under the laws of the
Netherlands (the "Dutch Borrower", and together with the US Borrower,
collectively the "Borrowers"), the financial institutions named therein (the
"Lenders"), The Bank of New York, as syndication agent, and Bank of America,
N.A., as administrative agent (the "Administrative Agent"), have entered into a
certain Credit Agreement dated as of the date hereof (as amended, restated,
supplemented or otherwise modified from time to time, the "Credit Agreement");
and

      WHEREAS, the US Borrower owns, directly or indirectly, a majority of the
issued and outstanding capital stock of each Guarantor and, as such, each
Guarantor will receive substantial and direct benefits from the extensions of
credit contemplated by the Credit Agreement and is entering into this Guaranty
to induce the Administrative Agent and the Lenders to enter into the Credit
Agreement and extend credit to the Borrowers thereunder and to induce the other
Guaranteed Creditors (as defined on Exhibit B attached hereto) to extend Related
Credit Arrangements (as defined on Exhibit B attached hereto) to the Borrowers
or any other Loan Party; and

      WHEREAS, the execution and delivery of this Guaranty is a condition
precedent to the obligation of the Lenders to extend credit to the Borrowers
pursuant to the Credit Agreement;

      NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration contained herein, the Guarantor hereby agrees as follows:

            1.    THE GUARANTY.

            (a) Each Guarantor hereby absolutely, continually, irrevocably and
unconditionally guarantees prompt, full and complete payment when due, whether
at stated maturity, upon acceleration or otherwise, and at all times thereafter,
of (i)(x) the principal of and interest on the Loans made by the Lenders to, and
any Notes held by the Lenders of, the Borrowers, or either of them as
applicable, and (y) all other amounts from time to time owing to the Lenders,
the Administrative Agent or any indemnified party by any Loan Party under the

<PAGE>

Credit Agreement, the Notes or the other Loan Documents, including without
limitation all "Obligations" (as defined in the Credit Agreement), and (ii)
principal, interest, fees, settlement or termination values, and all other
amounts from time to time owing to any Guaranteed Creditor in respect of any
Related Credit Arrangements, in each case, whether direct or indirect, absolute
or contingent, now existing or hereafter arising (collectively, the "Guaranteed
Debt") (collectively, the "Guaranteed Debt"). Each Guarantor's obligations under
this Guaranty are collectively referred individually as the "Guarantor's
Obligations" and collectively as the "Guarantors' Obligations". This is a
guaranty of payment, not a guaranty of collection. Notwithstanding the
foregoing, the liability of each Guarantor individually with respect to its
obligations under this Guaranty shall be limited to an aggregate amount equal to
the largest amount that would not render its obligations hereunder subject to
avoidance under Section 548 of the United States Bankruptcy Code or any
comparable provisions of any applicable state law.

            Each Guarantor agrees that it is jointly and severally, directly and
primarily liable for the Guaranteed Debt.

            (b) If there shall occur a default in payment or performance of any
of the Guaranteed Debt, whether principal, interest, premium, fee (including,
but not limited to, loan fees and attorney costs), settlement or termination
value, or otherwise, when and as the same shall become due, and after expiration
of any applicable grace period, whether according to the terms of the Credit
Agreement or any Related Credit Arrangement, by acceleration, termination or
otherwise, or upon the occurrence and during the continuance of any Event of
Default under the Credit Agreement, then the Guarantor will, upon demand thereof
by the Administrative Agent or, subject to Section 1(m) hereof, any other
Guaranteed Creditor, fully pay to the Administrative Agent, for the benefit of
the Lenders, or such Guaranteed Creditor, as applicable and subject to any
restriction on each Guarantor's Obligations set forth in Section 1 hereof, an
amount equal to all the applicable Guaranteed Debt then due and owing.

            (c) All payments by each Guarantor hereunder shall be paid in full,
without setoff or counterclaim or any deduction or withholding whatsoever,
including, without limitation, for any and all present and future taxes other
than Excluded Taxes (as defined in the Credit Agreement). In the event that any
Guarantor or any Guaranteed Creditor is required by law to make any such
non-excluded deduction or withholding (as a result of any change after the date
hereof in any requirement for a deduction or withholding), such Guarantor agrees
to pay on behalf of such Guaranteed Creditor such amount directly to the
appropriate person or entity, or if any Guarantor cannot legally comply with the
foregoing, such Guarantor shall pay to such Guaranteed Creditor such additional
amounts as will result in the receipt by such Person of the full amount payable
hereunder. Each Guarantor shall be entitled to refunds of amounts paid pursuant
hereto to the extent permitted by Section 3.01(e) of the Credit Agreement. Each
Guarantor shall promptly provide such Guaranteed Creditor with evidence of
payment of any such amount made on such Person's behalf.

            (d) Each Guarantor waives notice of the acceptance of this Guaranty
and of the extension or incurrence of the Guaranteed Debt or any part thereof.
Each Guarantor further waives all setoffs and counterclaims and presentment,
protest, notice (other than notices specifically required in the Loan
Documents), filing of claims with a court in the event of receivership,
bankruptcy or reorganization of the Borrowers, or either of them as applicable,

<PAGE>

demand or action on delinquency in respect of the Guaranteed Debt or any part
thereof, including any right to require any Guaranteed Creditor to sue the
Borrowers, or either of them as applicable, any other guarantor or any other
Person obligated with respect to the Guaranteed Debt or any part thereof, or
otherwise to enforce payment thereof against any collateral securing the
Guaranteed Debt or any part thereof.

      Each Guarantor hereby guarantees that such Guarantor's Obligations will be
paid in Dollars (except to the extent that any Obligation is required to be paid
in euro, such Guarantor shall pay such Obligation in euro) in same day funds at
the Administrative Agent's Office, on behalf of the applicable Guaranteed
Creditor, or with respect to demands permitted to be made directly by any
Guaranteed Creditor hereunder, at the applicable office of such Guaranteed
Creditor, as the case may be, regardless of any law, regulation or decree now or
hereafter in effect that might in any manner affect the Guaranteed Debt, or the
rights of the Guaranteed Creditors with respect thereto as against any Loan
Party, or cause or permit to be invoked any alteration in the time, amount or
manner of payment by any Loan Party of any or all of the Guaranteed Debt.
Payment obligations under this Guaranty shall not be discharged by an amount
paid in any currency other than Dollars or euro, as the case may be, whether
pursuant to judgment or otherwise. To the extent that a judgment is given in
respect of any amount due hereunder in currency other than the currency in which
the obligation subject to the judgment was originally denominated, the
provisions of Section 8.04 of the Credit Agreement shall apply.

            (e) Subject to Section 1(a) above, each Guarantor hereby agrees
that, to the fullest extent permitted by law, its obligations hereunder shall be
continuing, absolute and unconditional under any and all circumstances and not
subject to any reduction, limitation, impairment, termination, defense (other
than irrevocable payment in full of the Guaranteed Debt), setoff, counterclaim
or recoupment whatsoever (all of which are hereby expressly waived by it to the
fullest extent permitted by law), whether by reason of any claim of any
character whatsoever, including, without limitation, any claim of waiver,
release, surrender, alteration or compromise. The validity and enforceability of
this Guaranty shall not be impaired or affected by any of the following to the
extent permitted by law: (i) any extension, amendment, modification or renewal
of, or indulgence with respect to, or substitution for, the Guaranteed Debt or
any part thereof or any agreement relating thereto at any time; (ii) any failure
or omission to perfect or maintain any lien on, or preserve rights to, any
security or collateral or to enforce any right, power or remedy with respect to
the Guaranteed Debt or any part thereof or any agreement relating thereto, or
any collateral securing the Guaranteed Debt or any part thereof; (iii) any
waiver of any right, power or remedy or of any default with respect to the
Guaranteed Debt or any part thereof or any agreement relating thereto or with
respect to any collateral securing the Guaranteed Debt or any part thereof; (iv)
any release, surrender, compromise, settlement, waiver, subordination or
modification, with or without consideration, of any collateral securing the
Guaranteed Debt or any part thereof, any other guaranties with respect to the
Guaranteed Debt or any part thereof, or any other obligations of any person or
entity with respect to the Guaranteed Debt or any part thereof; (v) the
enforceability or validity of the Guaranteed Debt or any part thereof or the
genuineness, enforceability or validity of any agreement relating thereto or
with respect to any collateral securing the Guaranteed Debt or any part thereof;
(vi) the application of payments received from any source (other than any
Guarantor) to the payment of indebtedness other than the Guaranteed Debt, any
part thereof or amounts that are not covered by this Guaranty even though the
Guaranteed Creditors might

<PAGE>

lawfully have elected to apply such payments to any part or all of the
Guaranteed Debt or to amounts that are not covered by this Guaranty; (vii) any
change of ownership of any Loan Party or the insolvency, bankruptcy or any other
change in the legal status of any Loan Party; (viii) any change in, or the
imposition of, any law, decree, regulation or other governmental act which does
or might impair, delay or in any way affect the validity, enforceability or the
payment when due of the Guaranteed Debt; (ix) the failure of any Loan Party to
maintain in full force, validity or effect or to obtain or renew when required
all governmental and other approvals, licenses or consents required in
connection with the Guaranteed Debt or this Guaranty, or to take any other
action required in connection with the performance of all obligations pursuant
to the Guaranteed Debt or this Guaranty; (x) the existence of any claim, setoff
or other rights which any Guarantor may have at any time against any Loan Party,
any other guarantor in connection herewith or with any unrelated transaction or
any other Person in connection herewith; (xi) the Guaranteed Creditors'
election, in any case or proceeding instituted under chapter 11 of the United
States Bankruptcy Code, of the application of Section 1111(b)(2) of the United
States Bankruptcy Code or any comparable provision applicable to the Dutch
Borrower or its assets or operations under any applicable Debtor Relief Laws;
(xii) any borrowing, use of cash collateral, or grant of a security interest by
any Loan Party as debtor in possession, under Section 363 or 364 of the United
States Bankruptcy Code or any comparable provision applicable to the Dutch
Borrower or its assets or operations under any applicable Debtor Relief Laws;
(xiii) the disallowance of all or any portion of any of the Guaranteed
Creditors' claims for repayment of the Guaranteed Debt under Section 502 or 506
of the United States Bankruptcy Code or any comparable provision applicable to
the Dutch Borrower or its assets or operations under any applicable Debtor
Relief Laws; or (xiv) any other fact or circumstance which might otherwise
constitute grounds at law or equity for the discharge or release of any
Guarantor from its obligations hereunder (other than irrevocable payment in full
of the Guaranteed Debt), in each case above, all whether or not such Guarantor
shall have had notice or knowledge of any act or omission referred to in the
foregoing clauses (i) through (xiv) of this paragraph. It is agreed that each
Guarantor's liability hereunder is independent of any other guaranties or other
similar obligations at any time in effect with respect to the Guaranteed Debt or
any part thereof and that each Guarantor's liability hereunder may be enforced
regardless of the existence, validity, enforcement or non enforcement of any
such other guaranties or other obligations or any provision of any applicable
law or regulation purporting to prohibit payment by any Loan Party of the
Guaranteed Debt in the manner agreed upon by the Guaranteed Creditors and such
Loan Party.

            (f) Credit may be granted or continued from time to time by the
Guaranteed Creditors to the Borrowers, or either of them as applicable, without
notice to or authorization from any Guarantor regardless of any Loan Party's
financial or other condition at the time of any such grant or continuation. No
Guaranteed Creditor shall have an obligation to disclose or discuss with any
Guarantor its assessment of the financial condition of any Loan Party.

            (g) Until (but only upon) the irrevocable payment in full of the
Guaranteed Debt and the termination of all commitments of the Lenders to make
Credit Extensions and all commitments of any other Guaranteed Creditors to make
Related Credit Arrangements which could give rise to any Guaranteed Debt, (i) no
Guarantor shall have the right of subrogation, contribution or similar rights
with respect to the Guaranteed Debt, (ii) each Guarantor hereby waives any right
to enforce any remedy which any Guaranteed Creditor now has or may hereafter
have against the Borrowers, or either of them as applicable, any endorser or any
other

<PAGE>

guarantor of all or any part of the Guaranteed Debt, and (iii) each Guarantor
hereby waives any benefit of, and any right to participate in, any security or
collateral given to any Guaranteed Creditor to secure payment of the Guaranteed
Debt or any part thereof or any other liability of the Borrowers, or either of
them as applicable, to any Guaranteed Creditor. If any amounts are paid to any
Guarantor in violation of the foregoing limitation, then such amounts shall be
held in trust for the benefit of the Lenders or such other Guaranteed Creditor,
as applicable, and shall forthwith be paid by the Guarantor to the
Administrative Agent for the benefit of the Lenders or such other Guaranteed
Creditor, as applicable, for application to the Guaranteed Debt, if any, then
due and owing.

            (h) Except as specifically otherwise provided in the Loan Documents,
each Guarantor authorizes each Guaranteed Creditor to take any action or
exercise any remedy in good faith with respect to any collateral from time to
time securing the Guaranteed Debt, which the Guaranteed Creditors in their sole
discretion shall determine, without notice to any Guarantor.

            (i) In the event that any Guaranteed Creditor in its sole discretion
elects to give notice of any action with respect to any collateral securing the
Guaranteed Debt or any part thereof, ten days' written notice mailed to the
applicable Guarantor by ordinary mail at its address referred to in Section 5
shall be deemed reasonable notice of any matters contained in such notice. Each
Guarantor consents and agrees that no Guaranteed Creditor shall be under any
obligation to marshal any assets in favor of any Guarantor or against or in
payment of any or all of the Guaranteed Debt.

            (j) In the event that acceleration of the time for payment of any of
the Guaranteed Debt is stayed upon the insolvency, bankruptcy or reorganization
of any Loan Party, all such amounts shall nonetheless be payable to the
Guaranteed Creditors by the Guarantors during the continuance of an Event of
Default forthwith upon demand by the Administrative Agent. Each Guarantor
further agrees that, to the extent that any Loan Party makes a payment or
payments to any of the Guaranteed Creditors on the Guaranteed Debt or any
Guaranteed Creditor receives any proceeds of collateral or any other guaranty
securing the Guaranteed Debt, which payment or receipt of proceeds or any part
thereof is subsequently invalidated, declared to be fraudulent or preferential,
set aside or required to be returned or repaid to any Loan Party, its estate,
trustee, receiver, debtor in possession or any other party, including, without
limitation, any Guarantor, under any insolvency or bankruptcy law, state or
federal law, common law or equitable cause, then to the extent of such payment,
return or repayment, the Guaranteed Debt or part thereof which has been paid,
reduced or satisfied by such amount shall be reinstated and continued in full
force and effect as of the date when such initial payment, reduction or
satisfaction occurred as if such payment, reduction or satisfaction had never
occurred.

            (k) No delay on the part of any Guaranteed Creditor in the exercise
of any right, power or remedy shall operate as a waiver thereof, and no single
or partial exercise by any Guaranteed Creditor of any right, power or remedy
shall preclude any further exercise thereof; nor shall any amendment,
supplement, modification or waiver of any of the terms or provisions of this
Guaranty be binding upon the Guaranteed Creditors, except as set forth in
Section 10.01 of the Credit Agreement or as otherwise expressly set forth in a
writing duly signed and delivered on the Lenders' behalf by the Administrative
Agent with the consent of the Required

<PAGE>

Lenders or all of the Lenders, as the case may be, in each case as required by
Section 10.01 of the Credit Agreement; provided, however, no consent of the
Guaranteed Creditors shall be required in connection with the release of any
Guarantor from its obligations hereunder to the extent that such Guarantor is
disposed of pursuant to a transaction permitted by Section 7.04 or 7.05 of the
Credit Agreement. The failure by the Guaranteed Creditors at any time or times
hereafter to require strict performance by any Loan Party of any of the
provisions, warranties, terms and conditions contained in any promissory note,
pledge agreement, security agreement, agreement, guaranty, instrument or
document now or at any time or times hereafter executed pursuant to the terms
of, or in connection with, any Guaranteed Debt by any Loan Party or the
Guarantors and delivered to any Guaranteed Creditor shall not waive, affect or
diminish any right of any Guaranteed Creditor at any time or times hereafter to
demand strict performance thereof, and such right shall not be deemed to have
been waived by any act or knowledge of any Guaranteed Creditor, its agents,
officers or employees, unless such waiver is contained in an instrument in
writing duly signed and delivered (x) with respect to the Guaranteed Debt
described in Section 1(a)(i) hereof, on the Required Lenders' behalf by the
Administrative Agent and (y) with respect to the Guaranteed Debt described in
Section 1(a)(ii) hereof, by the Guaranteed Creditor party to such Related Credit
Arrangements. No waiver by any Guaranteed Creditor of any default shall operate
as a waiver of any other default or the same default on a future occasion, and
no action by any Guaranteed Creditor permitted hereunder shall in any way affect
or impair such Guaranteed Creditor's rights or powers, or the obligations of any
Guarantor under this Guaranty. The remedies herein are cumulative and not
exclusive of any other remedies available to the Guaranteed Creditors at law or
in equity. Any determination by a court of competent jurisdiction of the amount
of any Guaranteed Debt owing by the Borrowers, or either of them as applicable,
to the Guaranteed Creditors shall be conclusive and binding on each Guarantor
irrespective of whether such Guarantor was a party to the suit or action in
which such determination was made.

            (l) Notwithstanding any reference herein to any collateral securing
any of the Guaranteed Debt, it is acknowledged that, on the date hereof, neither
the Guarantor nor any other Loan Party has granted, or has any obligation to
grant, any security interest in or other lien on any of its property as security
for the Guaranteed Debt other than such obligations as the US Borrower may have
to "Cash Collateralize" L/C Obligations as and to the extent expressly provided
in the Credit Agreement.

            (m) Notwithstanding any other provision contained in this Guaranty,
(i) until the Facility Termination Date, from and after the occurrence and
during the continuance of any Event of Default, no Guaranteed Creditor shall be
entitled, except as expressly provided in the Credit Agreement, to institute any
action to enforce any right, power or remedy hereunder against any Guarantor in
respect of Guaranteed Debt arising under the Loan Documents, except by virtue of
the enforcement of the provisions hereof by the Administrative Agent on behalf
of such Guaranteed Creditors as provided herein and in the Credit Agreement and
otherwise available under applicable Laws, (ii) each Guaranteed Creditor, by its
execution of the Credit Agreement (or an Assignment and Assumption Agreement),
or by its acceptance (whether or not as a Lender) of any benefits hereunder
(including entering into any Related Credit Arrangements in reliance on the
terms hereof) (x) agrees (1) that it shall not have, prior to the Facility
Termination Date, any right to notice of any action or to consent to, direct or
object to any action hereunder or under any other Loan Document or otherwise in
respect of any Guarantor's

<PAGE>

Obligations relating to Guaranteed Debt described in Section (1)(a)(i) hereof
(including the release or modification of any Guarantor's Obligations or
security therefor) other than in any capacity it may have as a Lender and only
to the extent expressly provided in the Loan Documents, and (2) that any action
it may take or fail to take as a Guaranteed Creditor in respect of Guaranteed
Debt described in Section 1(a)(ii) hereof shall not impair or otherwise affect
the rights, powers and privileges of the Administrative Agent or any other
Guaranteed Creditor to enforce the terms hereof and of the other Loan Documents
in respect of all other Guaranteed Debt, and (y) acknowledges and accepts the
appointment of the Administrative Agent pursuant to the terms of the Credit
Agreement, and that with respect to the actions and omissions of the
Administrative Agent hereunder or otherwise relating hereto that do or may
affect such Guaranteed Creditor (including without limitation at all times after
the occurrence of the Facility Termination Date if at any such time it then
remains a Guaranteed Creditor), the Administrative Agent and its Related Parties
shall be entitled to all the rights, benefits and immunities conferred under
Article IX of the Credit Agreement, and (iii) following the occurrence of the
Facility Termination Date, the provisions of this Guaranty shall be deemed to
run severally to and for the benefit of each remaining Guaranteed Creditor, with
the effect and to the same extent as if each Guarantor had entered into this
Guaranty separately with each such remaining Guaranteed Creditor, such that (x)
the terms hereof may be modified by and between any such Guarantor and any such
Guaranteed Creditor without affecting the terms hereof as may then be in effect
as between any such Guarantor and any other Guaranteed Creditor, (y) no action,
omission or other event or circumstance arising between or affecting the
relative rights and duties of the Guarantor and any such Guaranteed Creditor
shall affect the relative rights and duties of any Guarantor and any other
Guaranteed Creditor, and (z) each remaining Guaranteed Creditor shall have the
right, power and authority to enforce the terms hereof for its benefit in its
own name in such manner as may be permitted by the terms hereof or otherwise by
applicable Laws. For purposes hereof, "Facility Termination Date" means the date
as of which all of the following shall have occurred: (A) the Borrowers shall
have permanently terminated the credit facilities under the Loan Documents by
final payment in full of all Outstanding Amounts, together with all accrued and
unpaid interest and fees thereon, other than (i) the undrawn portion of Letters
of Credit and (ii) all letter of credit fees relating thereto accruing after
such date (which fees shall be payable solely for the account of the L/C Issuer
and shall be computed (based on interest rates and the Applicable Rate then in
effect) on such undrawn amounts to the respective expiry dates of the Letters of
Credit), in each case as have been fully Cash Collateralized or as to which
other arrangements with respect thereto satisfactory to the Administrative Agent
and the L/C Issuer shall have been made; (B) all Commitments shall have
terminated or expired; and (C) the Borrowers and each other Loan Party shall
have fully, finally and irrevocably paid and satisfied in full all of their
respective obligations and liabilities arising under the Loan Documents (except
for future obligations consisting of continuing indemnities and other contingent
Obligations of the Borrowers or any Loan Party that may be owing to any Person
pursuant to the Loan Documents and expressly survive termination of the Credit
Agreement or any other Loan Document). Each Guarantor acknowledges and agrees to
the forgoing provisions of this Section 1(m).

            2.    REPRESENTATIONS AND WARRANTIES.

            Each Guarantor hereby represents and warrants to the Administrative
Agent, each Lender and the other Guaranteed Creditors that:

<PAGE>

            (a) Existence, Qualification and Power; Compliance with Laws. Such
Guarantor (i) is a corporation or a limited liability company, as applicable,
duly organized, validly existing and in good standing under the Laws (as defined

jurisdiction where its ownership, lease or operation of properties or the
conduct of its business requires such qualification or license, and (iv) is in
compliance with all Laws, except in each case referred to in clause (ii), clause
(iii) or this clause (iv), to the extent that failure to do so could not
reasonably be expected to have a Material Adverse Effect.

            (b) Authorization: No Contravention. The execution, delivery and
performance by such Guarantor of this Guaranty has been duly authorized by all
necessary corporate or other organizational action, and do not and will not (i)
contravene the terms of any of such Guarantor's Organization Documents, (ii)
conflict with or result in any breach or contravention of, or the creation of
any Lien under, any material Contractual Obligation to which such Guarantor is a
party or any order, injunction, writ or decree of any Governmental Authority to
which such Guarantor or its property is subject, except as would not have a
Material Adverse Effect, or (iii) violate any Law, except as would not have a
Material Adverse Effect.

            (c) Governmental Authorization. No approval, consent, exemption,
authorization, or other action by, or notice to, or filing with, any
Governmental Authority is necessary or required in connection with the
execution, delivery or performance by, or enforcement against, such Guarantor of
this Guaranty except for any of such foregoing as may be required in connection
with the exercise of remedies under the Loan Documents.

            (d) Binding Effect. This Guaranty has been duly executed and
delivered by such Guarantor. This Guaranty constitutes a legal, valid and
binding obligation of such Guarantor, enforceable against such Guarantor in
accordance with its terms except as may be limited by any applicable bankruptcy,
insolvency, reorganization, moratorium, or similar laws affecting the
enforcement of creditors' rights generally which may be in effect and to general
principles of equity.

            (e) Other. Each Guarantor represents and warrants that all
representations and warranties relating to such Guarantor contained in Article V
of the Credit Agreement are true and correct insofar as they relate to such
Guarantor.

      Each Guarantor agrees that all of the foregoing representations and
warranties in paragraphs (a) through (e) above and the preceding sentence shall
be deemed to have been made by such Guarantor on the date hereof and, except to
the extent that such representations and warranties specifically refer to an
earlier date, in which case they shall be true and correct as of such earlier
date, on the date of each Credit Extension on and as of the date of such Credit
Extension.

<PAGE>

            3. COVENANTS. Each Guarantor hereby agrees that until all Guaranteed
Debt described in Section 1(a)(i) has been paid in full and any and all
documents relating thereto have been terminated, it shall comply with all
covenants relating to it contained in Articles VI and VII of the Credit
Agreement (except Sections 6.12 and 6.15(b) and (c)).

            4. JOINDER. Each Person who shall at any time execute and deliver to
the Administrative Agent a Guaranty Joinder Agreement substantially in the form
attached as Exhibit A hereto or otherwise agreed to by the Administrative Agent
shall thereupon irrevocably, absolutely and unconditionally become a party
hereto and obligated hereunder as a Guarantor, and all references herein and in
the other Loan Documents to the Guarantors or to the parties to this Guaranty
shall be deemed to include such Person as a Guarantor hereunder.

            5.   MISCELLANEOUS.

            (a) Subject to the provisions of Sections 1(j) and 1(k), this
Guaranty shall continue in effect (i) as to the Administrative Agent and the
Lenders, until the Credit Agreement and all other commitments of the Lenders to
make Credit Extensions which could give rise to Guaranteed Debt described in
Section 1(a)(i) have terminated and such Guaranteed Debt and all other amounts
payable hereunder have been paid in full and (ii) as to any other Guaranteed
Creditors, until all Related Credit Arrangements which could give rise to
Guaranteed Debt have been fully or finally satisfied or other arrangements
satisfactory to the respective parties to each such Related Credit Arrangement
have been made in lieu of the continuation of this Guaranty.

            (b) Each Guarantor confirms and ratifies Section 10.08 of the Credit
Agreement and agrees that the Lenders shall have, relative to each Guarantor,
the set-off rights provided therein. In addition to any rights and remedies of
the Administrative Agent and the Lenders provided by law, upon the occurrence
and during the continuance of any Event of Default, the Administrative Agent and
each Lender is authorized at any time and from time to time, without prior
notice to any Guarantor, any such notice being waived by each Guarantor to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final (but not trust
accounts)) at any time held by, and other indebtedness at any time owing by,
such Lender to or for the credit or the account of any Guarantor against any and
all Guaranteed Debt then due and owing to such Lender, now or hereafter
existing, irrespective of whether or not the Administrative Agent or such Lender
shall have made demand under this Guaranty or any other Loan Document. Each
Lender agrees promptly to notify the applicable Guarantor and the Administrative
Agent after any such set-off and application made by such Lender; provided,
however, that the failure to give such notice shall not affect the validity of
such set-off and application.

            (c) Each Guarantor agrees to pay all reasonable costs, fees and out
of pocket expenses (including reasonable attorney costs of the Administrative
Agent, any Lender or any other Guaranteed Creditor) incurred by the
Administrative Agent, any Lender or any other Guaranteed Creditor in collecting
or enforcing the obligations of any Guarantor under this Guaranty.

            (d) This Guaranty shall bind each Guarantor and its respective
successors and assigns and shall inure to the benefit of the Guaranteed
Creditors and its successors and assigns

<PAGE>

permitted pursuant to Section 10.06 of the Credit Agreement. All references
herein to the Borrowers, or either of them as applicable, shall be deemed to
include its successors and assigns including, without limitation, a receiver,

                      LIBBEY GLASS INC. GUARANTY AGREEMENT

      THIS GUARANTY AGREEMENT (as amended, revised, modified, supplemented or
amended and restated from time to time, this "Guaranty") is entered into as of
June 24, 2004 by LIBBEY GLASS INC., a Delaware corporation (the "Guarantor"), in
favor of BANK OF AMERICA, N.A., in its capacity as administrative agent for each
of the Lenders (the "Lenders") now or hereafter party to the Credit Agreement
(as defined below). All capitalized terms used but not otherwise defined herein
shall have the meaning ascribed to such term by the Credit Agreement.

                                   WITNESSETH:

      WHEREAS, the Guarantor, Libbey Europe B.V., a company organized and
existing under the laws of the Netherlands (the "Dutch Borrower", and together
with the Guarantor, collectively the "Borrowers"), the Lenders named therein,
The Bank of New York, as syndication agent, and Bank of America, N.A., as
administrative agent (the "Administrative Agent"), have entered into a certain
Credit Agreement dated as of the date hereof (as amended, revised, modified,
supplemented or amended and restated from time to time, the "Credit Agreement");
and

      WHEREAS, the Guarantor owns, directly or indirectly, 100% of the issued
and outstanding capital stock of the Dutch Borrower and will receive substantial
and direct benefits from the extensions of credit contemplated by the Credit
Agreement and is entering into this Guaranty to induce the Administrative Agent
and the Lenders to enter into the Credit Agreement and extend credit to it and
to the Dutch Borrower thereunder; and

      WHEREAS, the execution and delivery of this Guaranty is a condition
precedent to the obligation of the Lenders to extend credit to the Guarantor and
the Dutch Borrower pursuant to the Credit Agreement;

      NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration and as an inducement to the Lenders to enter into the
Credit Agreement and extend credit to the Guarantor and the Dutch Borrower, the
Guarantor hereby agrees as follows:

      1.    THE GUARANTY.

            (a) The Guarantor hereby absolutely, continually, irrevocably and
unconditionally guarantees to the Administrative Agent for the benefit of the
Lenders prompt, full and complete payment when due, whether at stated maturity,
upon acceleration or otherwise, and at all times thereafter, of (i) the
principal of and interest on the Loans made by the Lenders to, and any Notes
held by the Lenders of, the Dutch Borrower and (ii) all other amounts from time
to time owing to the Lenders, the Administrative Agent or any indemnified party
under the Credit Agreement, the Notes or the other Loan Documents, including
without limitation all "Obligations" (as defined in the Credit Agreement) of the
Dutch Borrower, whether direct or

<PAGE>

indirect, absolute or contingent, now existing or hereafter arising
(collectively, the "Guaranteed Debt"). The Guarantor's obligations under this
Guaranty are collectively referred to as the "Guarantor's Obligations". This is
a guaranty of payment, not a guaranty of collection.

            (b) If there shall occur a default in payment or performance of any
of the Guaranteed Debt, whether principal, interest, premium, fee (including,
but not limited to, loan fees and attorney costs), settlement or termination
value, or otherwise, when and as the same shall become due, and after expiration
of any applicable grace period, whether according to the terms of the Credit
Agreement, by acceleration, termination or otherwise, or upon the occurrence and
during the continuance of any Event of Default under the Credit Agreement, then
the Guarantor will, upon demand thereof by the Administrative Agent, fully pay
to the Administrative Agent, for the benefit of the Lenders, an amount equal to
all the applicable Guaranteed Debt then due and owing.

            (c) All payments by the Guarantor hereunder shall be paid in full,
without setoff or counterclaim or any deduction or withholding whatsoever,
including, without limitation, for any and all present and future taxes other
than Excluded Taxes. In the event that the Guarantor, the Administrative Agent
or any Lender is required by law to make any such non-excluded deduction or
withholding (as a result of any change after the date hereof in any requirement
for a deduction or withholding), the Guarantor agrees to pay on behalf of the
Administrative Agent or the applicable Lender such amount directly to the
appropriate person or entity, or if the Guarantor cannot legally comply with the
foregoing, the Guarantor shall pay to the Administrative Agent or such Lender
such additional amounts as will result in the receipt by such Person of the full
amount payable hereunder. The Guarantor shall be entitled to refunds of amounts
paid pursuant hereto to the extent permitted by Section 3.01(e) of the Credit
Agreement. The Guarantor shall promptly provide the Administrative Agent or the
applicable Lender with evidence of payment of any such amount made on such
Person's behalf.

            (d) The Guarantor waives notice of the acceptance of this Guaranty
and of the extension or incurrence of the Guaranteed Debt or any part thereof.
The Guarantor further waives all setoffs and counterclaims and presentment,
protest, notice (other than notices specifically required in the Loan
Documents), filing of claims with a court in the event of receivership,
bankruptcy or reorganization of the Dutch Borrower demand or action on
delinquency in respect of the Guaranteed Debt or any part thereof, including any
right to require the Administrative Agent or the Lenders to sue the Dutch
Borrower, any other guarantor or any other Person obligated with respect to the
Guaranteed Debt or any part thereof, or otherwise to enforce payment thereof
against any collateral securing the Guaranteed Debt or any part thereof.

      The Guarantor hereby guarantees that the Guarantor's Obligations will be
paid in Dollars (except to the extent that any Obligation is required to be paid
in euro, the Guarantor shall pay such Obligation in euro) in same day funds at
the Administrative Agent's Office, regardless of any law, regulation or decree
now or hereafter in effect that might in any manner affect the Guaranteed Debt,
or the rights of the Administrative Agent or any Lender with respect thereto as
against the Dutch Borrower, or cause or permit to be invoked any alteration in
the time, amount or manner of payment by the Dutch Borrower or any or all of the
Guaranteed Debt. Payment obligations under this Guaranty shall not be discharged
by an amount paid in any currency other

                                       2
<PAGE>

than US Dollars or euro, as the case may be, whether pursuant to judgment or
otherwise. To the extent that a judgment is given in respect of any amount due
hereunder in currency other than the currency in which the obligation subject to
the judgment was originally denominated, the provisions of Section 8.04 of the
Credit Agreement shall apply.

            (e) The Guarantor hereby agrees that, to the fullest extent
permitted by law, its obligations hereunder shall be continuing, absolute and
unconditional under any and all circumstances and not subject to any reduction,
limitation, impairment, termination, defense (other than irrevocable payment in
full of the Guaranteed Debt), setoff, counterclaim or recoupment whatsoever (all
of which are hereby expressly waived by it to the fullest extent permitted by
law), whether by reason of any claim of any character whatsoever, including,
without limitation, any claim of waiver, release, surrender, alteration or
compromise. The validity and enforceability of this Guaranty shall not be
impaired or affected by any of the following to the extent permitted by law: (i)
any extension, amendment, modification or renewal of, or indulgence with respect
to, or substitution for, the Guaranteed Debt or any part thereof or any
agreement relating thereto at any time without notice to or consent of the
Guarantor except as expressly required by the Credit Agreement; (ii) any failure
or omission to perfect or maintain any lien on, or preserve rights to, any
security or collateral or to enforce any right, power or remedy with respect to
the Guaranteed Debt or any part thereof or any agreement relating thereto, or
any collateral securing the Guaranteed Debt or any part thereof; (iii) any
waiver of any right, power or remedy or of any default with respect to the
Guaranteed Debt or any part thereof or any agreement relating thereto or with
respect to any collateral securing the Guaranteed Debt or any part thereof; (iv)
any release, surrender, compromise, settlement, waiver, subordination or
modification, with or without consideration, of any collateral securing the
Guaranteed Debt or any part thereof, any other guaranties with respect to the
Guaranteed Debt or any part thereof, or any other obligations of any person or
entity with respect to the Guaranteed Debt or any part thereof; (v) the
enforceability or validity of the Guaranteed Debt or any part thereof or the
genuineness, enforceability or validity of any agreement relating thereto or
with respect to any collateral securing the Guaranteed Debt or any part thereof;
(vi) the application of payments received from any source (other than the
Guarantor) to the payment of indebtedness other than the Guaranteed Debt, any
part thereof or amounts which are not covered by this Guaranty even though the
Lenders might lawfully have elected to apply such payments to any part or all of
the Guaranteed Debt or to amounts which are not covered by this Guaranty; (vii)
any change of ownership of the Dutch Borrower or the insolvency, bankruptcy or
any other change in the legal status of the Dutch Borrower; (viii) any change
in, or the imposition of, any law, decree, regulation or other governmental act
which does or might impair, delay or in any way affect the validity,
enforceability or the payment when due of the Guaranteed Debt; (ix) the failure
of the Dutch Borrower to maintain in full force, validity or effect or to obtain
or renew when required all governmental and other approvals, licenses or
consents required in connection with the Guaranteed Debt or this Guaranty, or to
take any other action required in connection with the performance of all
obligations pursuant to the Guaranteed Debt or this Guaranty; (x) the existence
of any claim, setoff or other rights which the Guarantor may have at any time
against the Dutch Borrower, any other guarantor in connection herewith or with
any unrelated transaction or any other Person in connection herewith; (xi) the
Lenders' election, in any case or proceeding instituted under chapter 11 of the
United States Bankruptcy Code, of the application of Section 1111(b)(2) of the
United States Bankruptcy Code or any comparable provision applicable to the
Dutch Borrower or its assets or operations under any applicable Debtor Relief

                                       3
<PAGE>

Laws; (xii) any borrowing, use of cash collateral, or grant of a security
interest by the Dutch Borrower, as debtor in possession, under Section 363 or
364 of the United States Bankruptcy Code or any comparable provision applicable
to the Dutch Borrower or its assets or operations under any applicable Debtor
Relief Laws; (xiii) the disallowance of all or any portion of any of the
Lenders' claims for repayment of the Guaranteed Debt under Section 502 or 506 of
the United States Bankruptcy Code or any comparable provision applicable to the
Dutch Borrower or its assets or operations under any applicable Debtor Relief
Laws; or (xiv) any other fact or circumstance which might otherwise constitute
grounds at law or equity for the discharge or release of the Guarantor from its
obligations hereunder (other than irrevocable payment in full of the Guaranteed
Debt), in each case above, all whether or not the Guarantor shall have had
notice or knowledge of any act or omission referred to in the foregoing clauses
(i) through (xiv) of this paragraph. It is agreed that the Guarantor's liability
hereunder is independent of any other guaranties or other similar obligations at
any time in effect with respect to the Guaranteed Debt or any part thereof and
that the Guarantor's liability hereunder may be enforced regardless of the
existence, validity, enforcement or non-enforcement of any such other guaranties
or other obligations or any provision of any applicable law or regulation
purporting to prohibit payment by the Dutch Borrower of the Guaranteed Debt in
the manner agreed upon among the Administrative Agent, the Lenders and the Dutch
Borrower.

            (f) Credit may be granted or continued from time to time by the
Lenders to the Dutch Borrower without notice to or authorization from the
Guarantor (other than as expressly provided in the Credit Agreement) regardless
of the Dutch Borrower's financial or other condition at the time of any such
grant or continuation. Neither the Administrative Agent nor any Lender shall
have an obligation to disclose or discuss with the Guarantor its assessment of
the financial condition of the Dutch Borrower. No waiver contained herein of (i)
notices to be given or received by the Guarantor or (ii) borrowing procedures
which require action by the Guarantor, shall be deemed to render any Credit
Agreement provisions regarding the same of no effect; provided, however, the
failure of any party to give, perform or comply with any such notice or
borrowing procedure provision shall not constitute a defense to or otherwise
impair the enforcement of this Guaranty.

            (g) Until (but only upon) the irrevocable payment in full of the
Guaranteed Debt and termination of all commitments of the Lenders to make Credit
Extensions which could give rise to any Guaranteed Debt, (i) the Guarantor shall
have no right of subrogation, contribution or similar rights with respect to the
Guaranteed Debt, (ii) the Guarantor hereby waives any right to enforce any
remedy which the Administrative Agent or the Lenders now have or may hereafter
have against the Dutch Borrower, any endorser or any other guarantor of all or
any part of the Guaranteed Debt, and (iii) the Guarantor hereby waives any
benefit of, and any right to participate in, any security or collateral given to
the Administrative Agent or the Lenders to secure payment of the Guaranteed Debt
or any part thereof or any other liability of the Dutch Borrower to the
Administrative Agent or the Lenders. If any amounts are paid to the Guarantor in
violation of the foregoing limitation, then such amounts shall be held in trust
for the benefit of the Lenders and shall forthwith be paid by the Guarantor to
the Administrative Agent for application to the Guaranteed Debt, if any, then
due and owing.

            (h) Except as specifically otherwise provided in the Loan Documents,
the Guarantor authorizes the Administrative Agent and the Lenders to take any
action or exercise

                                       4
<PAGE>

any remedy in good faith with respect to any collateral from time to time
securing the Guaranteed Debt, which the Lenders in their sole discretion shall
determine, without notice to the Guarantor.

            (i) In the event the Administrative Agent or the Lenders in their
sole discretion elect to give notice of any action with respect to any
collateral securing the Guaranteed Debt or any part thereof, ten days' written
notice mailed to the Guarantor by ordinary mail at its address referred to in
Section 3(i) shall be deemed reasonable notice of any matters contained in such
notice. The Guarantor consents and agrees that neither the Administrative Agent
nor the Lenders shall be under any obligation to marshal any assets in favor of
the Guarantor or against or in payment of any or all of the Guaranteed Debt.

            (j) In the event that acceleration of the time for payment of any of
the Guaranteed Debt is stayed upon the insolvency, bankruptcy or reorganization
of the Dutch Borrower, all such amounts shall nonetheless be payable by the
Guarantor during the continuance of an Event of Default forthwith upon demand by
the Administrative Agent. The Guarantor further agrees that, to the extent that
the Dutch Borrower makes a payment or payments to any of the Lenders on the
Guaranteed Debt, or the Administrative Agent or the Lenders receive any proceeds
of collateral or any other guaranty securing the Guaranteed Debt, which payment
or receipt of proceeds or any part thereof is subsequently invalidated, declared
to be fraudulent or preferential, set aside or required to be returned or repaid
to the Dutch Borrower, its estate, trustee, receiver, debtor in possession or
any other party, including, without limitation, the Guarantor, under any
insolvency or bankruptcy law, state or federal law, common law or equitable
cause, then to the extent of such payment, return or repayment, the Guaranteed
Debt or part thereof which has been paid, reduced or satisfied by such amount
shall be reinstated and continued in full force and effect as of the date when
such initial payment, reduction or satisfaction occurred as if such payment,
reduction or satisfaction had never occurred.

            (k) No delay on the part of the Administrative Agent or the Lenders
in the exercise of any right, power or remedy shall operate as a waiver thereof,
and no single or partial exercise by the Administrative Agent or the Lenders of
any right, power or remedy shall preclude any further exercise thereof; nor
shall any amendment, supplement, modification or waiver of any of the terms or
provisions of this Guaranty be binding upon the Administrative Agent or the
Lenders, except as set forth in Section 10.01 of the Credit Agreement or as
otherwise expressly set forth in a writing duly signed and delivered on the
Lenders' behalf by the Administrative Agent with the consent of the Required
Lenders or all of the Lenders, as the case may be, in each case as required by
Section 10.01 of the Credit Agreement. The failure by the Administrative Agent
or the Lenders at any time or times hereafter to require strict performance by
the Dutch Borrower or the Guarantor of any of the provisions, warranties, terms
and conditions contained in any promissory note, pledge agreement, security
agreement, agreement, guaranty, instrument or document now or at any time or
times hereafter executed pursuant to the terms of, or in connection with, the
Credit Agreement by the Dutch Borrower or the Guarantors and delivered to the
Administrative Agent or the Lenders shall not waive, affect or diminish any
right of the Administrative Agent or the Lenders at any time or times hereafter
to demand strict performance thereof, and such right shall not be deemed to have
been waived by any act or knowledge of the Administrative Agent or the Lenders,
their agents, officers or employees, unless such waiver is contained in an
instrument in writing duly signed and delivered on the

                                       5
<PAGE>

Required Lenders' behalf by the Administrative Agent. No waiver by the
Administrative Agent or the Lenders of any default shall operate as a waiver of
any other default or the same default on a future occasion, and no action by the
Administrative Agent or the Required Lenders permitted hereunder shall in any
way affect or impair the Administrative Agent's or the Lenders' rights or
powers, or the obligations of the Guarantor under this Guaranty. The remedies
herein are cumulative and not exclusive of any other remedies available to the
Administrative Agent and the Lenders at law or in equity. Any determination by a
court of competent jurisdiction of the amount of any Guaranteed Debt owing by
the Dutch Borrower to the Lenders shall be conclusive and binding on the
Guarantor irrespective of whether the Guarantor was a party to the suit or
action in which such determination was made.

            (l) Notwithstanding any reference herein to any collateral securing
any of the Guaranteed Debt, it is acknowledged that, on the date hereof, neither
the Dutch Borrower nor the Guarantor has granted, or has any obligation to
grant, any security interest in or other lien on any of its property as security
for the Guaranteed Debt other than such obligations as the US Borrower may have
to "Cash Collateralize" L/C Obligations as and to the extent expressly provided
in the Credit Agreement.

      2.    REPRESENTATIONS AND WARRANTIES.

      The Guarantor hereby represents and warrants to the Administrative Agent
and the Lenders that:

            (a) Existence, Qualification and Power; Compliance with Laws. The
Guarantor (i) is a corporation duly organized, validly existing and in good
standing under the Laws of the jurisdiction of its incorporation, (ii) has all
requisite power and authority and all governmental licenses, authorizations,
consents and approvals to own its assets, carry on its business and to execute,
deliver, and perform its obligations under this Guaranty, (iii) is duly
qualified and is licensed and in good standing under the Laws of each
jurisdiction where its ownership, lease or operation of properties or the
conduct of its business requires such qualification or license, and (iv) is in
compliance with all Laws, except in each case referred to in clause (ii), clause
(iii) or this clause (iv), to the extent that failure to do so could not
reasonably be expected to have a Material Adverse Effect.

            (b) Authorization; No Contravention. The execution, delivery and
performance by the Guarantor of this Guaranty has been duly authorized by all
necessary corporate or other organizational action, and do not and will not (i)
contravene the terms of any of the Guarantor's Organization Documents, (ii)
conflict with or result in any breach or contravention of, or the creation of
any Lien under, any material Contractual Obligation to which the Guarantor is a
party or, any order, injunction, writ or decree of any Governmental Authority to
which the Guarantor or its property is subject, except as would not have a
Material Adverse Effect, or (iii) violate any Law, except as would not have a
Material Adverse Effect.

            (c) Governmental Authorization. No approval, consent, exemption,
authorization, or other action by, or notice to, or filing with, any
Governmental Authority is necessary or required in connection with the
execution, delivery or performance by, or

                                       6
<PAGE>

enforcement against, the Guarantor of this Guaranty except for any of such of
the foregoing as may be required in connection with the exercise of remedies
under the Loan Documents.

            (d) Binding Effect. This Guaranty has been duly executed and
delivered by the Guarantor. This Guaranty constitutes a legal, valid and binding
obligation of the Guarantor, enforceable against the Guarantor in accordance
with its terms except as may be limited by any applicable bankruptcy,
insolvency, reorganization, moratorium, or similar laws affecting the
enforcement of creditors' rights generally which may be in effect and to general
principles of equity.

      The Guarantor agrees that all of the foregoing representations and
warranties in paragraphs (a) through (d) above shall be deemed to have been made
by the Guarantor on the date hereof and, except to the extent that such
representations and warranties specifically refer to an earlier date, in which
case they shall be true and correct as of such earlier date, on the date of each
Credit Extension on and as of the date of such Credit Extension.

      3.    MISCELLANEOUS.

            (a) Subject to the provisions of Section 1(j), this Guaranty shall
continue in effect until the Credit Agreement and all other commitments of the
Lenders to make Credit Extensions which could give rise to Guaranteed Debt have
terminated and the Guaranteed Debt and all other amounts payable hereunder have
been paid in full.

            (b) The Guarantor confirms and ratifies Section 10.08 of the Credit
Agreement and agrees that the Lenders shall have, relative to the Guarantor, the
set-off rights provided therein. In addition to any rights and remedies of the
Lenders provided by law, upon the occurrence and during the continuance of any
Event of Default, each Lender is authorized at any time and from time to time,
without prior notice to the Guarantor, any such notice being waived by the
Guarantor to the fullest extent permitted by law, to set off and apply any and
all deposits (general or special, time or demand, provisional or final (but not
trust accounts)) at any time held by, and other indebtedness at any time owing
by, such Lender to or for the credit or the account of the Guarantor against any
and all Guaranteed Debt then due and owing to such Lender, now or hereafter
existing, irrespective of whether or not such Lender shall have made demand
under this Guaranty or any other Loan Document. Each Lender agrees promptly to
notify the Guarantor and the Administrative Agent after any such set-off and
application made by such Lender; provided, however, that the failure to give
such notice shall not affect the validity of such set-off and application.

            (c) The Guarantor agrees to pay all reasonable costs, fees and
out-of-pocket expenses (including reasonable attorney costs of the
Administrative Agent and any Lender) incurred by the Administrative Agent or any
Lender in collecting or enforcing the obligations of the Guarantor under this
Guaranty

            (d) This Guaranty shall bind the Guarantor and its successors and
assigns and shall inure to the benefit of the Administrative Agent, the Lenders
and their successors and assigns permitted pursuant to Section 10.06 of the
Credit Agreement. All references herein to

                                       7
<PAGE>

the Dutch Borrower shall be deemed to include its successors and assigns
including, without limitation, a receiver, trustee or debtor in possession of or
for the Dutch Borrower.

            (e) THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT THE ADMINISTRATIVE AGENT,
EACH LENDER AND THE GUARANTOR SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

            (f) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY MAY
BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK OR OF THE
UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND BY EXECUTION AND
DELIVERY OF THIS AGREEMENT, THE `GUARANTOR CONSENTS, FOR ITSELF AND IN RESPECT
OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE
GUARANTOR IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE
LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY
NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING 1N SUCH
JURISDICTION IN RESPECT OF THIS GUARANTY. THE GUARANTOR WAIVES PERSONAL SERVICE
OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS
PERMITTED BY THE LAW OF SUCH STATE.

            (g) THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING HEREUNDER OR IN ANY WAY
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE GUARANTOR, THE
ADMINISTRATIVE AGENT OR THE LENDERS OR ANY OF THEM WITH RESPECT TO ANY LOAN
DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING
OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND
THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR
CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT THE
ADMINISTRATIVE AGENT OR ANY LENDER MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF
THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR
TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

            (h) Wherever possible, each provision of this Guaranty shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Guaranty shall be prohibited by or invalid under
such 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 Guaranty.

            (i) Except as otherwise expressly provided herein, any notice
required or desired to be served, given or delivered to any party hereto under
this Guaranty shall be given in the manner and with the effect set forth in
Section 10.02(a) of the Credit Agreement.
