                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
Vitrocrisa, S.A. de C.V.
Monterrey, N.L.
 
     We have audited the accompanying balance sheet of Vitrocrisa, S.A. de C.V.
(a wholly-owned subsidiary of Vitro, Sociedad Anonima) as of December 31, 1996,
and the related statements of operations, variations in stockholders' equity and
changes in financial position for the year then ended, all expressed in
thousands of constant Mexican pesos as of June 30, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with auditing standards generally
accepted in Mexico which are substantially the same as those followed in the
United States. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement and that they are prepared in accordance with accounting
principles generally accepted in Mexico. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Vitrocrisa, S.A. de C.V. as
of December 31, 1996, and the results of its operations, variations in its
stockholders' equity and changes in its financial position for the year ended at
December 31, 1996, in conformity with accounting principles generally accepted
in Mexico.
 
     Accounting principles generally accepted in Mexico differ in certain
significant respects from accounting principles generally accepted in the United
States. The application of the latter would have affected the determination of
net income for the year ended December 31, 1996 and the determination of
stockholders' equity at December 31, 1996 to the extent summarized in note 15.
 
     The accompanying financial statements and the independent auditors' report
have been translated into English language for the convenience of the reader.

  b) Basis of presentation
 
     The financial statements presented herein are expressed in Thousands of
constant Mexican pesos as of June 30, 1997.
 
2. PRINCIPAL ACCOUNTING POLICIES:
 
  a) Accounting method for the treatment of the effects of inflation
 
     The financial statements of the Company have been prepared in accordance
with Bulletin B-10, "Recognition of the Effects of Inflation in the Financial
Information", as amended, issued by the Mexican Institute of Public Accountants
(IMCP), which recognizes the effects of inflation. The Third Amendment to
Bulletin B-10, requires the restatement of all comparative financial statements
to constant pesos as of the date of the most recent balance sheet presented. For
that purpose, the company uses the "Indice Nacional de Precios al Consumidor"
(Mexican National Consumer Price Index: "INPC"), published by Banco de Mexico.
 
     Bulletin B-12 sets the rules related to the statement of changes in
financial position. This statement presents the sources and uses of funds of
changes in financial position during the period measured as the differences, in
constant pesos, between the beginning and ending balances adjusted by the excess
(shortfall) in restatement of capital. As regulated by Bulletin B-12, the
monetary effect and the effect of changes in exchange rates are not considered
non-cash items in the determination of funds generated from operations due to
the fact they affect the purchasing power of the entity.
 
     The following is a description of the items that have been restated and of
the methods used:
 
     - Inventories and cost of sales
 
          Inventories are valued at the price of the last purchase made during
     the period, or at standard cost, without exceeding the net realizable
     value. Cost of sales is determined by using the standard cost at the time
     of sale.

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED
 
     - Land, buildings, machinery and equipment
 
          Investments in land, buildings, machinery and equipment (collectively
     "fixed assets"), including expenditures for renewals and improvements which
     extend useful lives, are capitalized. Until December 31, 1996, fixed assets
     were restated at their current replacement cost as determined from
     appraisals performed by independent appraisers. In accordance with the
     Fifth Amendment to Bulletin B-10 issued by the IMCP, which is effective
     January 1, 1997, the Company restates (1) machinery and equipment from
     foreign origin by means of the index of inflation of the country of origin
     and translating to the corresponding exchange rate at the date of the
     valuation and (2) land, buildings, machinery and equipment of Mexican
     origin by means of factors derived from INPC.
 
          Depreciation is calculated using the straight-line method, taking into
     consideration the useful life of the asset, in order to depreciate the
     original cost and the revaluation. The depreciation begins in the month in
     which the asset comes into service. The useful lives of the assets are as
     follows:

                                                                                  --------

     - Investment in shares
 
          The investment in shares in which the Company holds less than 10% of
     capital stock, are accounted for at their acquisition cost.
 
     - Amortizable expenses
 
          The balances of amortizable expenses, and the accumulated and period
     amortization are restated using INPC.
 
     - Insufficiency in restatement of capital
 
          This item, which is an element of stockholders' equity, reflects the
     accumulated effect of holding non-monetary assets and the effect of the
     initial monetary position gain or loss. The accumulated effect of holding
     non-monetary assets represents the increase in the specific values of
     non-monetary assets in excess of or below the increase attributable to
     general inflation as measured by the INPC.
 
     - Restatement of capital stock and retained earnings
 
          Capital stock and retained earnings are restated using the INPC from
     the respective dates such capital was contributed or income generated to
     the date of the most recent balance sheet presented.
 
     - Exchange fluctuations
 
          Exchange gains or losses included in the cost of financing are
     calculated by translating monetary assets and liabilities denominated in
     foreign currencies at the exchange rate in effect at the end of each month.
 
     - Results due to monetary position
 
          The monetary position reflects the result of holding monetary assets
     and liabilities during periods of inflation. Values stated in current
     monetary units represent a decreasing purchasing power as time goes by.
     This means that losses are incurred by holding monetary assets over time,
     whereas gains are realized by maintaining monetary liabilities. The net
     effect is presented in the income statement for the year as part of the
     total financing cost.

  b) Maintenance expenses
 
     Maintenance and repair expenses are recorded as costs and expenses in the
period when they are incurred.
 
  c) Amortization of deferred charges
 
     Amortization is calculated using the straight-line method. The rates vary
according to the type of amortizable expense.
 
  d) Seniority premiums, pension plans and severance payments
 
     Statutory seniority premiums and pension plans for all personnel are
considered as costs in the periods in which services are rendered. Periodic
costs are calculated in accordance with the accounting pronouncement Bulletin
D-3, issued by the IMCP, and the actuarial computations were made by independent
actuaries using estimates of the salaries that will be in effect at the time of
payment. Personnel not yet eligible for seniority premiums are also taken into
account, with any necessary adjustments made in accordance with the probability
of their acquiring the required seniority. The cost of past service is amortized
over the average period required for workers to reach their retirement age.
 
     Severance payments are charged to expense in the year in which such
payments are made.
 
  e) Income tax and profit sharing to workers
 
     Income tax and profit sharing to workers expense are computed in accordance
with the partial liability method, as required by Mexican Accounting Bulletin
D-4 issued by the IMCP, under which deferred taxes are provided for
identifiable, non-recurring timing differences and that are expected to reverse
over a definite period of time, at the tax rates in effect at the end of each
period.

     As of December 31, 1996, short-term bank loans in the amount of U.S.
$57,000 thousands of dollars used to finance export sales of the Company have
been reclassified as long-term debt, because the Company expects to obtain
similar financing in the future to finance export sales. In addition, the
Company has a committed long-term standby credit line with certain commercial
banks available to finance such export sales.
 
     In some of the Company's long-term debt agreements certain restrictions and
covenants are set forth that require the maintenance of various financial
ratios.

</TABLE>
 
Adjustments for pension costs and accrued vacation cost were not material
individually or in the aggregate, for any of the periods presented.
 
  a) Effects of inflationary accounting
 
     A significant difference between Mexican and U.S. GAAP relates to the
formal adoption in Mexico of inflationary accounting, which mitigates the
effects of inflation on financial information. Under Mexican GAAP, all basic
financial statements (including those of prior years) and related notes are
presented in pesos of purchasing power at the end of the latest period
presented. Inventories and fixed assets are valued at replacement cost or are
restated by applying INPC growth factors. Stockholders' equity components are
restated by applying INPC growth factors from the date on which the component
was contributed or generated.
 
  b) Deferred Income Tax:
 
     Under Mexican GAAP, deferred taxes are provided only for identifiable,
nonrecurring timing differences which are expected to reverse over a definite
period of time. For U.S. GAAP purpose, the Company has applied Statement of
Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes".
 
     Under SFAS 109, deferred tax assets and liabilities are recognized for
future tax consequences of temporary differences between the financial statement
carrying amounts of assets and liabilities and their tax bases. Deferred

tax assets are also recognized for the estimated future effects of tax loss
carry forwards. Deferred tax assets are reduced by any tax benefits that are not
expected to be realized.
 
     The significant components of the deferred tax assets and liabilities for
purposes of U.S. GAAP reconciliation are as follows:

  c) Deferred employees' profit sharing
 
     The Company calculates a deferred employees' profit sharing liability for
U.S. GAAP purposes based on temporary differences between the financial
reporting bases and employees' profit sharing bases of assets. Under U.S. GAAP,
employee profit sharing expense would be considered as a component of operating
expenses.
 
     The significant components of the deferred employees' profit sharing for
purposes of U.S. GAAP reconciliation are as follows:

  d) Effects of merge
 
     For U.S. GAAP purposes the business combination of Proveedora del Hogar,
S.A. de C.V. was accounted for as an enterprise under common control similar to
a pooling of interest and the financial information is consolidated as of
January 1, 1996.
 
  e) Other Differences and Supplemental U.S. GAAP Disclosures
 
     1) Extraordinary Items. -- Mexican GAAP requires that utilization of tax
        loss carry forwards be classified as extraordinary items in the
        statement of operations, whereas U.S. GAAP requires the benefit from
        utilization of tax loss carry forwards to be classified as a component
        of income tax expense attributable to continuing operations. The
        benefits from utilization of tax loss carry forwards were Ps 80,302 for
        the

        year ended December 31, 1996 and Ps 36,909 (unaudited) and Ps 50,437
        (unaudited) for the six months ended June 30, 1997 and 1996,
        respectively.
 
     2) Post-retirement Benefits -- Under U.S. GAAP, Statement of financial
        Accounting Standards No. 106, "Employer's Accounting for Post-retirement
        Benefits Other Than Pensions" (SFAS 106) requires accrual of
        post-retirement benefits other than pensions (such as health care
        benefits) during the years an employee provides services. The Company
        does not and is not required to provide post-retirement benefits.
 
     3) Pension Disclosures. -- The Company maintains pension plans and
        seniority premium plans. The Company adopted Bulletin D-3 issued by the
        IMCP, the accounting treatment for pensions set forth in this Bulletin
        are substantially the same as those set forth in Statement of Financial
        Accounting Standards No. 87 "Employer's Accounting For Pensions" (SFAS
        87). The company records the pensions cost determined by actuarial
        computations, as described in notes 2(d) and 7. The differences between
        principles applied by the Company under Mexican GAAP and requirements of
        SFAS No. 87 are not material.
 
     For purposes of determining pension cost and seniority premium under U.S.
GAAP the Company applies SFAS 87. The disclosures under SFAS 87 for the Company
are presented below.
 
     Pension and seniority premium costs are summarized below:

original maturity of ninety days or less, consisting primarily of Mexican
Government treasury bonds and money market instruments to be classified as cash
equivalents.
 
     5) Fair value of financial instruments -- Statement of Financial Accounting
Standards No. 107. "Disclosures about Fair Value of Financial Instruments"
requires disclosure of the estimated fair values of certain financial
instruments. The estimated fair value amounts have been determined using
available market information or other appropriate valuation methodologies that
require considerable judgment in interpreting market data and developing
estimates. Accordingly, the estimates presented herein are not necessarily
indicative of the amounts that the Company could realize in a current market
exchange. The use of different market assumptions and/or estimation
methodologies may have a material effect on the estimated fair value amounts.
The carrying amount of the Company's financial instruments approximate their
estimated fair values.
 
     The fair value information presented herein is based on information
available to management as of December 31, 1996. Although management is not
aware of any factors that would significantly affect the estimated fair valued
amounts, such amounts have not been comprehensively revalued for purposes of
these financial statements since that date and, therefore, the current estimates
of fair value may differ significantly form the amounts presented herein.
 
     6) Earnings Per Common share in Accordance with U.S. GAAP -- Earnings per
share in accordance with US GAAP are based on the weighted average number of
common shares outstanding during each period. Primary earnings per share are
based upon, 166,682,900 shares for the year ended December 31, 1996 and the six
months ended June 30, 1997 (unaudited) and 1996 (unaudited). Earnings per common
share computed in accordance with US. GAAP are presented below:

                          INDEPENDENT AUDITORS' REPORT
 
     We have audited the accompanying combined balance sheet of WorldCrisa
Corporation and Crisa Corporation (the "Companies"), wholly owned subsidiaries
of American Assets Holding Company and indirect wholly owned subsidiaries of
Vitro, S.A., as of December 31, 1996, and the related combined statements of
operations and accumulated deficit and cash flows for the year then ended. These
combined financial statements are the responsibility of the Companies'
management. Our responsibility is to express an opinion on these combined
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the combined financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.
 
     In our opinion, such combined financial statements present fairly, in all
material respects, the financial position of the Companies as of December 31,
1996, and the results of their operations and cash flows for the year then ended
in conformity with generally accepted accounting principles.
 
     As discussed in Note 2 to the combined financial statements, the Companies
changed their method of accounting for capitalized costs included in inventory
during 1996.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Nature of Business -- WorldCrisa Corporation ("WorldCrisa") and Crisa
Corporation ("Crisa") (the "Companies") are wholly owned subsidiaries of
American Assets Holding Company ("American"), which is a wholly owned subsidiary
of Vitro, Sociedad Anonima ("Vitro, S.A."), a Mexican publicly owned
corporation. WorldCrisa imports and markets tableware products, including china,
glass and silverware, for the food service industry, principally in the United
States. Crisa is the exclusive U.S. distributor of household glassware, glass
fixtures, leaded crystal products, enamel cookware and tableware manufactured by
Mexican subsidiaries of the Vitro consolidated group.
 
     The primary subsidiaries of WorldCrisa are World Tableware Corporation
("WTC"); a U.S. holding company for investment in World Tableware International,
Ltd. ("WTI-Taiwan"); a Taiwan holding company for investment in World Tableware
International (Europe) S.A. ("WTI-Europe"); and a Belgian trading company with a
registered Taiwan branch providing purchasing services to WorldCrisa and
affiliates and to third parties.
 
     Basis of Presentation -- The combined financial statements are prepared in
accordance with generally accepted accounting principles in the United States.
The combined financial statements include the accounts of Crisa, WorldCrisa and
the wholly owned subsidiaries of WorldCrisa as described above. Substantially
all transactions are denominated in U.S. dollars. All significant intercompany
accounts and transactions have been eliminated.
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amount of assets and
liabilities and the disclosure of contingent assets and liabilities at the date
of the financial statements and reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
     Cash and Cash Equivalents -- The Companies consider all highly liquid debt
instruments and investments readily convertible to cash and with a maturity of
three months or less at the date of purchase to be cash equivalents.
 
     Inventory -- Inventory is stated at the lower of cost or market. Cost,
which includes materials, purchased components, direct labor, import tariffs,
storage and other purchasing costs, is determined under the average cost method
of accounting. Inventory is composed primarily of finished goods.
 
     Property and Equipment -- Property and equipment are stated at cost less
accumulated depreciation. Depreciation expense is computed using the
straight-line method over estimated useful lives of three to five years.
Replacements, renewals and significant improvements are treated as capital
additions. Maintenance and repairs are charged to expense as incurred.
 
     Excess of Cost Over Net Assets of Acquired Business -- Excess of cost over
net assets of acquired business is being amortized on a straight-line basis over
30 years. On an annual basis, WorldCrisa compares the carrying value of this
asset to an estimate of WorldCrisa's fair value to evaluate the reasonableness
of the carrying value and remaining amortization period. Accumulated
amortization totaled $771 as of December 31, 1996.
 
     Income Taxes -- Deferred tax assets and liabilities are recognized for
future tax consequences attributable to differences between financial statement
carrying amounts of existing assets and liabilities and their respective tax
basis. These temporary differences relate primarily to the allowance for
doubtful accounts receivable, which is not currently deductible for tax
purposes.

31, 1996, are included in the accompanying combined financial statements.
 
     The functional currency of the Taiwan subsidiary is the U.S. dollar since
cash flows and financing activities are primarily denominated in U.S. dollars.
The monetary assets and liabilities of Taiwan have been translated at year-end
exchange rates; inventories, property, and nonmonetary assets and liabilities
have been translated at historical rates. Income and expense accounts are
translated at the average rates in effect, except that depreciation and cost of
sales are translated at historical rates. All exchange gains and losses from
remeasurement of monetary assets and liabilities are recognized currently in
income.
 
2. CHANGE IN ACCOUNTING
 
     In 1996, the Companies changed their method of accounting for capitalized
costs included in inventory. The Companies capitalized additional expenses
incurred during 1996 which had been incurred but were not capitalized in
previous years. In management's opinion, the capitalization of these additional
expenses better reflects the costs of obtaining and storing inventory. This
change resulted in an increase in inventory as of December 31, 1996, and a
reduction in cost of goods sold of $183 for the year ended December 31, 1996.
The cumulative effect as of January 1, 1996, of this accounting change was $214.
 
3. TRANSACTIONS WITH RELATED PARTIES
 
     During 1996, Crisa purchased $26,334 in glassware and other supplies from
VitroCrisa, a wholly owned subsidiary of Vitro, S.A.
 
     During 1996, Crisa paid $1,795 in administrative charges to VitroCrisa.
These charges represent certain administrative and other services performed on
Crisa's behalf. In the accompanying combined statement of operations, the
administrative charges are allocated as follows: $282 is included in general and
administrative, $96 is included in selling and marketing, and $1,417 is included
in shipping and warehouse.
 
     As of December 31, 1996, due from affiliated companies includes $1,176 due
from VitroCrisa and $83 due from Vitro, S.A.
 
     As of December 31, 1996, due to affiliated companies includes $1,182 due to
VitroCrisa and $56 due to Acero Porcelanizado, S.A. de C.V., a wholly owned
subsidiary of VitroCrisa, for enamelware purchased during 1996.

</TABLE>
 
     The revolving credit facility and two notes payable with the Bank of New
York are part of an overall loan agreement (the "Agreement") that permits
maximum loans in total of the lesser of $16,000, less certain adjustments,
including the aggregate amount of outstanding letters of credit, inventory
targeted by WorldCrisa as slow-moving, and additional inventory reserves or the
sum of 85% of eligible accounts receivable and 55% of eligible inventory also
adjusted for certain items. As of December 31, 1996, WorldCrisa had $2,600 in
available credit under the Agreement. The Bank of New York's advances are
secured by all receivables, equipment, inventory, general intangibles and other
rights of WorldCrisa. The Agreement also contains financial and other covenants,
including but not limited to calculation of minimum net worth, current ratio and
debt to equity ratio, and also includes limitations on capital expenditures and
new indebtedness. Vitro, S.A. has guaranteed $3,000 of any outstanding balance
under the Agreement.
 
As of December 31, 1996, WorldCrisa was in violation of several financial
covenants and has not received a waiver from the Bank of New York. These
violations constituted an event of default, and the bank, therefore, reserves
the right to call the outstanding balance due. Accordingly, the entire balance
of advances from the Bank of New York has been classified as current (see Note
9).
 
     The revolving loan agreement with Laredo National Bank ("Laredo") expired
on June 14, 1997, and Crisa failed to pay off the outstanding balance as of that
date. Attempts to refinance the loan with Laredo failed, and Crisa made
arrangements for alternative financing to pay off the loan (see Note 9).
 
6. INCOME TAXES
 
     In 1996, the Companies were included in the consolidated federal tax return
of certain Vitro, S.A. companies. Consequently, in 1996, the Companies
recognized income tax expense or benefit approximating that which would have
resulted from filing separate returns. The federal tax sharing policy of Vitro,
S.A. provides for the Companies to receive benefit for losses when such losses
would have been utilized on a stand-alone basis.

          Total                                                                $23

</TABLE>
 
     Differences between the Companies' effective tax rate and the federal
statutory rate of 34% are primarily attributable to the effects of tax-basis net
operating losses, federal taxes on certain foreign income, tax effects of
temporary differences related to purchase accounting adjustments and the effect
of certain special compensation arrangements.
 
     At December 31, 1996, Crisa had net operating loss carryforwards of $723,
which begin expiring in 2003. In addition, Crisa had alternative minimum tax
credit carryforwards of $240, which have no expiration date.
 
     WorldCrisa has U.S. net operating losses of $6,587, which may be carried
forward to offset future net income through 2011. Pursuant to the federal tax
sharing policy of Vitro, S.A., WorldCrisa is entitled to receive the benefit of
the current net operating loss. However, in 1995, WorldCrisa recorded a tax
liability under the tax sharing policy due to foreign dividend income. Vitro,
S.A. agreed to hold harmless the payment of the liability resulting from the
dividend income eliminating WorldCrisa's ability to carry back losses against
1995 income. Therefore, the asset generated by the net operating losses is fully
reserved as of December 31, 1996, in the combined financial statements due to
WorldCrisa's inability to utilize the losses on a stand-alone basis.
 
     WorldCrisa also has Taiwan tax loss carryforwards of approximately $700,
which can be carried forward to offset future profits recognized in Taiwan.
Approximately $276 of such carryforwards expire in 1997, with the remaining
amounts expiring in 1998 and 1999.
 
     The Companies' utilization of net operating losses could be limited due to
changes in ownership, including those described in Note 10.
 
     Net current deferred income taxes included in the accompanying combined
balance sheet at December 31, 1996, consist of the following:

opinion on the basic combined statements of operations and accumulated deficit
and of cash flows taken as a whole. The supplemental combining statement of
operations is presented for purposes of additional analysis and is not a
required part of the basic combined financial statements. This supplemental
schedule is the responsibility of the Companies' management. The supplemental

the basic combined financial statements and, in our opinion, is fairly stated in
all material respects when considered in relation to the basic combined
financial statements taken as a whole.

                                  LIBBEY INC.
 
             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
     On August 29, 1997 Libbey Inc. (the "Company") closed on a series of
transactions with Vitro S.A. ("Vitro") and certain of its subsidiaries. The
acquisition includes: (a) the Company acquiring through subsidiaries a
forty-nine percent (49%) equity interest in: (i) Vitrocrisa, S.A. de C.V.
("Vitrocrisa"), (ii) Vitrocrisa Holding, S.A. de C.V. ("Vitrocrisa Holding"),
(iii) Crisa Libbey, S.A. de C.V. ("Crisa Libbey") and (iv) Crisa Industrial,
L.L.C. ("Crisa Industrial") from Vitro and certain of its subsidiaries, with
Vitro, or its subsidiary Crisa Corporation ("Crisa") in the case of Crisa
Industrial, being the owner of the remaining fifty-one percent (51%) equity
interest in such entities; and (b) the Company acquiring through a subsidiary
certain assets and assuming certain liabilities of the business operated as
WorldCrisa Corporation from WorldCrisa Corporation ("World Tableware").
Reciprocal distribution agreements have been established, whereby the Company
becomes the distributor of Vitrocrisa glass tableware products in the United
States and Canada, and Vitrocrisa becomes the distributor of Libbey glass
tableware products in Mexico, Central and South America. The cash purchase price
is approximately $100 million plus the funding or assumption of certain
liabilities of WorldCrisa and was financed through the Company's $380 million
amended revolving credit facility, that terminates May, 2002 (filed as Exhibit
10.25 to Registrant's Quarterly Report on Form 10-Q for the quarter ended June
30, 1997). The purchase price was determined through arm's length negotiations.
 
     The following Unaudited Pro Forma Consolidated Financial Information is
based on the historical financial statements of the Company, Vitrocrisa, Crisa
and World Tableware adjusted to give effect to the transactions and the
financing thereof. The financial information of Vitrocrisa, Crisa and World
Tableware has been presented on a combined basis ("Acquired Companies") based
upon the form of the transaction as described above. Accordingly, the World
Tableware and retail business of Crisa in the U.S. have been presented on a
combined basis, while the 49% investment interests have been accounted for in
accordance with the equity method of accounting. The 49% investment interests
include Vitrocrisa and Crisa Industrial. The Unaudited Pro Forma Consolidated
Statements of Income for the year ended December 31, 1996 and six months ended
June 30, 1997 give effect to the acquisition as if it had occurred on January 1,
1996. The Pro Forma Unaudited Consolidated Balance Sheet gives effect to the
acquisition as if it had occurred on June 30, 1997. The pro forma adjustments
are based upon available information and certain assumptions that management
believes are reasonable.
 
     The acquisition was accounted for under the purchase method of accounting.
The total purchase price for the acquisition has been allocated to tangible and
identifiable intangible assets and liabilities based upon management's estimates
of their fair value. The allocation of the purchase price for the acquisition is
subject to revision when additional information concerning asset and liability
valuation is obtained. In management's opinion, the asset and liability
valuation for the acquisition will not be materially different from the pro
forma information presented. For purposes of presenting pro forma results, no
changes in revenues or expenses have been made to reflect the results of any
modification to operations that might have been made had the acquisition been
consummated at the beginning of 1996.
 
     The Unaudited Pro Forma Consolidated Information does not purport to
represent what the Company's results of operations would actually have been had
the acquisition actually occurred on January 1, 1996, or to project the
Company's results of operations for any future period.

                  actual customs duty, import tax, or other tax, fee, or charge
                  required by a governmental authority for goods imported from a
                  foreign country into the country imposing such charge. For
                  purposes of this Agreement, the term "FREIGHT" shall mean the
                  actual cost of transportation charges incurred to move goods
                  from the plant of manufacture by Vitrocrisa to the warehouse
                  used by Libbey Glass at Laredo, Texas or such other location
                  at the USA/Mexico border as is, from time to time, designated
                  by Libbey Glass plus all taxes imposed directly upon such
                  cost. For purposes of this Agreement, the term "STANDARD COST"
                  shall mean the standard cost of production employed by
                  Vitrocrisa in its manufacturing operation at the time goods
                  are manufactured which cost shall closely approximate the
                  actual cost of production at the time the standards are
                  established for the period for which they are established in
                  accordance with generally accepted accounting practices
                  consistently applied.

         (b)      From the date of this Agreement until the third anniversary of
                  this Agreement, Standard Cost for stock SKU's shall be
                  expressed in United States of America dollars and shall remain
                  in effect for one year. After the third anniversary of this
                  Agreement, the Manufacturer and Distributor agree to review
                  the method of determining Standard Cost for SKU's and will
                  review the assumptions for the United States of America
                  dollar/Mexico peso exchange rates and the inflation rates on a
                  quarterly basis and will agree to consider adjustments to
                  pricing for material deviations from such assumptions.
                  Non-stock and made to order items will be priced on a case by
                  case basis, and such terms may include quarterly adjustments
                  to the assumed United States of America dollar/Mexican peso
                  exchange rates and inflation rates as mutually agreed. Any
                  estimates or assumptions, whether during the first three years
                  of this Agreement or thereafter, of the United States of
                  America dollar/Mexican peso exchange rate or inflation rate
                  that are included in determining Standard Cost will be
                  included in the discussions with Libbey and must be reasonable
                  in light of the then-existing market forecasts of such by
                  reputable third parties.

         (c)      Once the Standard Cost is established with respect to an item,
                  unless revised by mutual agreement, such Standard Cost shall
                  remain in effect for the balance of the calendar year and
                  thereafter until revised in conjunction with the adoption and
                  approval of the Vitrocrisa annual operating budget by its
                  board of directors. Notwithstanding the foregoing, the parties
                  may by mutual agreement from time to time, for as long as
                  there is mutual agreement, use a formula or methodology other
                  than actual cost to compute either or both Duty and Freight,
                  but in no case shall the charge to Libbey Glass for Duty and
                  Freight be increased retroactively above the amount included
                  in the Landed Duty Paid Price initially charged to Libbey.

         Section 5.5 With respect to Vitrocrisa Glass Tableware products listed
in catalogs and selling sheets published by Libbey Glass, the discounts given by
Libbey Glass with respect to Glass Tableware manufactured by Vitrocrisa will be
substantially the same as established by Libbey Glass for Glass Tableware
manufactured by it and listed in such catalogs and selling sheets. Other Glass
Tableware products purchased by Libbey Glass will be priced and discounted by
Libbey Glass in the manner determined by it in its sole and absolute discretion
to be appropriate and consistent with the purposes of this Agreement.

         Section 5.6 Vitrocrisa shall keep, or cause to be kept, full and
accurate records and books of account of its costs and expenses relating to the
production of the Glass Tableware prepared in accordance with generally accepted
accounting principles in effect in Mexico, at its facilities in Monterrey,
Mexico. Libbey Glass, or an independent firm of certified public accountants
designated by Libbey Glass, shall at any reasonable time or times, but not more
often than twice in any calendar year, have the right to inspect, examine, and
audit all pertinent records and books in the possession of Vitrocrisa pertaining
to its operations and inspect and observe the operation of Vitrocrisa's facility
in Mexico for the purpose of verifying the calculations of the price of the
products under this Agreement, including, without limitation, Vitrocrisa's
Standard Costs, the cost of Freight, and the cost of Duty.

         Section 5.7 Libbey Glass and its Affiliates that sell Glass Tableware
purchased by Crisa shall keep, or cause to be kept, full and accurate records
and books of account of its costs, expenses, sales, and rebates relating to the
sale of the Glass Tableware purchased from Crisa, prepared in accordance with
generally accepted accounting principles in effect in the United States, at its
facilities in Toledo, Ohio. Crisa, or an independent firm of certified public
accountants designated by Vitrocrisa, shall at any reasonable time or times, but
not more often than twice in any calendar year, have the right to inspect,
examine, and audit all pertinent records and books in the possession of Libbey
Glass and its Affiliates that sell Glass Tableware purchased by Crisa pertaining
to the sale of Glass Tableware purchased from Crisa for the purpose of verifying
the calculations of the profit sharing under this Agreement including, without
limitation, (a) during the first three years of this Agreement, sales and
rebates, and (b) after the third anniversary of this Agreement, sales,
marketing, distributing, general, and administrative expenses, new product
development costs paid to third parties, mold costs, and rebates paid with
respect to products sold by Crisa hereunder.

         Section 5.8 Notwithstanding the foregoing, from time to time by mutual
agreement in writing, Libbey Glass, Crisa, and Vitrocrisa may agree upon special
pricing, special terms, or special profit sharing for any particular transaction
whereby Libbey Glass wishes to purchase Glass Tableware to meet a competitive
situation or otherwise obtain a particular piece of business in the Territory in
which case such mutual agreement shall supersede the pricing, terms and profit
sharing set forth above.

         Section 5.9 All payments by Libbey Glass to Crisa will be in US
dollars.

         Section 5.10 On and after the third anniversary of this Agreement the
amount of the Libbey Glass Expense Allocation set forth in SECTION 5.3 may be
reviewed annually at the 

<PAGE>   7



request of either Vitrocrisa or Libbey Glass and changed prospectively, upward
or downward, to some other percentage or method of computation as is necessary
to more accurately compensate (but not over compensate) Libbey Glass for its
full, direct and indirect, costs of distributing Vitrocrisa Glass Tableware
hereunder, including, without limitation, the Channels of Distribution where the
Glass Tableware is sold and the sales, marketing, distributing, general, and
administrative expenses allocable to such sales, and new product development
costs paid to third parties allocable to such sales. If mold costs allocable to
such sales are paid by Vitrocrisa, amortization of such costs will be included
in the Standard Cost. If mold costs allocable to such sales are paid by Libbey
Glass, the mold amortization expense will be included as a new product
development cost.

         Section 5.11 The methodology of computing the amount to be paid by
Crisa to Vitrocrisa pursuant to SECTION 5.1 and by Libbey Glass to Crisa
pursuant to SECTION 5.2 to purchase Glass Tableware hereunder sets forth the
intended sharing of profits and margins among Vitrocrisa, Crisa, and Libbey
Glass with respect to Glass Tableware sold hereunder. If any change in the
methodology of computing such prices is required in order to comply with
governmental regulations or legal requirements and such change would have a
material adverse economic effect on either Vitrocrisa, Crisa, or Libbey Glass
with respect to the profits and margins intended to be shared hereunder,
Vitrocrisa, Crisa, and Libbey Glass agree to negotiate in good faith another
methodology of computing such price to meet governmental regulations and legal
requirements and to place Vitro and Libbey in the same relative economic
position with respect to the sharing of profits and margins as is intended by
this ARTICLE V.

         Section 5.12 At the date of this Agreement, as its initial purchase,
Libbey Glass agrees to purchase from Crisa, and Crisa agrees to sell to Libbey
Glass, Glass Tableware held in Crisa's warehouse at Laredo, Texas for sale to
customers in the Territory at the price set forth in SECTION 5.2. For the
initial purchase, to the extent the book value of the Glass Tableware is less
than or more than the Landed Duty Price Paid, after the time for return of such
Glass Tableware has expired, Crisa will issue a credit or debit memo, as
appropriate, to Libbey Glass for forty-nine percent (49%) of the difference. In
addition to Glass Tableware, Crisa agrees to sell to Libbey, and Libbey agrees
to purchase at book value from Crisa, any accessories and packaging supplies
held in the Laredo Warehouse which are to be assembled or repackaged with Glass
Tableware to be sold to customers in the Territory. Terms for this sale are 45
days, net, or at Libbey's option, return of all or any portion of the Glass
Tableware, accessories, and packaging supplies to Crisa at the warehouse in
Laredo, Texas for full credit. Crisa shall then repatriate those returned
products to Vitrocrisa to be sold in Mexico or any other country other than
those in the Territory.

                                   ARTICLE VI
                              PERFORMANCE STANDARD

         Section 6.1 Libbey Glass and Vitrocrisa agree to use their best efforts
to carry out the sales plans agreed upon in the annual operating budgets which
will derive from the broader guidelines of the ongoing three-year strategic
plans of Vitrocrisa, as such budgets and strategic plans may be approved by
extraordinary directors action of the board of directors of Vitrocrisa.

         Section 6.2 Expected sales by Distributor of Glass Tableware in the
Territory in each of the calendar years 1998, 1999, and 2000 (herein "EXPECTED
SALES") will be measured by the actual dollar sales of Glass Tableware in the
Territory in calendar year 1997 plus a growth rate as set forth on SCHEDULE 4 to
this Agreement, subject to assigned production capacity consistent with
forecasted sales, competitive and expected fill rates, inventory, product
availability, and reasonable flexibility in response to business opportunities
and subject to the absence of any currency crises or unplanned increases in
import Duty.

         (a)      To allow Vitrocrisa to move from current fill rates to
                  Distributor's standards, order fill rates defined as
                  quantities shipped on time as ordered shall not be less than
                  the amount set forth on SCHEDULE 5 to this Agreement. Order
                  fill rates require that Glass Tableware is shipped in the
                  quantities, at the times and in the manner requested in full
                  conformity with the order. Quantities required from Vitrocrisa
                  should be within the daily capacity assigned to the
                  Distributor for each annual operating budget unless otherwise
                  mutually agreed, i.e., if there is available capacity over the
                  minimum assigned daily capacity there would be flexibility to
                  assign this extra capacity to the Distributor.

         (b)      As part of the annual operating budget discussion, the
                  Expected Sales may be adjusted up or down by mutual agreement
                  of Distributor and Vitrocrisa if warranted by general business
                  conditions in the Territory, competitive conditions in the
                  Territory, and growth as reported in recognized indexes such
                  as the Restaurant and Institutions Index.

         (c)      In determining the payment by Distributor for a shortfall in
                  Expected Sales for a calendar year (i) a shortfall allowance
                  of fifteen percent (15%) of Expected Sales shall be allowed
                  before any calculation of the amount of payment is made and
                  (ii) Distributor and Vitrocrisa shall examine and take into
                  account through an appropriate adjustment in Expected Sales
                  any extraneous events and any events beyond the reasonable
                  control of the Distributor (as set forth in ARTICLE IX) which
                  resulted in the shortfall.

         (d)      In the event the Distributor fails to achieve the Expected
                  Sales in the Territory, Distributor will pay Crisa its share
                  of the Lost Profits (as defined on SCHEDULE 6 to this
                  Agreement) based upon (i) the Average Operating Margin
                  attained on sales of Glass Tableware in the Territory during
                  the calendar year times (ii) the shortfall in sales in excess
                  of fifteen percent (15%) of the Expected Sales as determined
                  in accordance with SECTION 6.2(c), and Crisa will pay
                  Vitrocrisa its share of such Lost Profits, all in accordance
                  with the procedures established hereunder in ARTICLE V for the
                  sharing of profits on sales by Distributor. The term "AVERAGE
                  OPERATING MARGIN" is defined as total Adjusted Gross Profit
                  divided by total net invoiced selling price of Glass Tableware
                  for a calendar year.

<PAGE>   9



         (e)      Distributor will pay to Crisa the Lost Profits within sixty
                  (60) days following the end of the calendar year, and Crisa
                  shall pay Vitrocrisa its share at the time established in
                  ARTICLE V hereof for the distribution of Vitrocrisa's share of
                  the Lost Profits.

         Section 6.3 After the calendar year 2000, the Distributor and
management of Vitrocrisa, in connection with the preparation of the annual
operating budget for consideration and adoption by extraordinary directors
action of the board of directors of Vitrocrisa, shall review and discuss the
future direction, expectations, and strategies for sales in the Territory with
any impasses being resolved pursuant to the same procedures established for
deadlocks and impasses between the shareholders or between the directors of
Vitrocrisa in the Vitrocrisa, S.A. de C.V. Shareholders Agreement, dated of even
date, unless otherwise mutually agreed. Quantities required from Vitrocrisa
should be within the capacity assigned to the Distributor for each annual
operating budget unless otherwise mutually agreed, i.e., if there is available
capacity over the minimum assigned daily capacity there would be flexibility to
assign this extra capacity to the Distributor.

                                   ARTICLE VII
                              OPERATING PROCEDURES

         Section 7.1 Distributor shall maintain its own offices and places of
business and pay all of its own expenses in connection with the sale and
distribution of Glass Tableware under this Agreement, except as otherwise
provided herein.

         Section 7.2 Distributor is designated to serve customers in the
Territory. Any inquiries or orders for Manufacturer's brand of Glass Tableware
from customers outside of the Territory will be referred by Distributor to
Manufacturer.

         Section 7.3 Manufacturer shall furnish Distributor in connection with
the Glass Tableware to be distributed hereunder a reasonable number of catalogs
and existing sales literature which the Manufacturer may, from time to time,
have in connection with its own sales, but the Manufacturer shall not be
obligated to generate or create any catalogs or sales literature for
Distributor.

         Section 7.4 The relationship between the parties hereto shall be one of
independent contractors. Neither the Distributor nor the Manufacturer shall be
empowered to have any authority to act for the other, make any commitment on
behalf of the other, make any agreement on behalf of the other, make any payment
on behalf of the other, nor otherwise obligate the other in any way. Neither
Distributor nor Manufacturer shall hold itself out as having any authority to
act in any way for the other unless otherwise specifically agreed in writing.

         Section 7.5 All Glass Tableware sold hereunder shall be transferred to
Distributor free and clear of all liens and encumbrances.

<PAGE>   10



         Section 7.6 Manufacturer shall secure and apply all packaging for Glass
Tableware sold hereunder and unless otherwise agreed in writing with respect to
any particular transaction the prices charged for Glass Tableware shall be
deemed to include all packaging expenses.

         Section 7.7 Regular current stock items to be procured and imported
hereunder will be ordered at levels that correspond to a mutually agreed upon
level per SKU. Should the Distributor require quantities in excess of the agreed
threshold levels, a separate Make and Ship order must be processed with specific
quantities and release dates. Failure by the Distributor to honor the Make and
Ship order by the release date or within thirty (30) days thereafter will result
in shipment and invoicing of the full order, as originally specified.

         Section 7.8 In some cases, Distributor may desire and request Specially
Differentiated Product to be created specifically for its customers in the
Territory, which new items are beyond the normal stock collection of the
Manufacturer. These will be private items and may require new molds and cartons.
Unless otherwise, agreed, the cost of developing new molds and cartons is the
responsibility of the Distributor and will be invoiced to the Distributor at
actual out of pocket costs paid to third party vendors in arms length
transactions. Four-color photography, artwork separations, and final layout for
any retail packaging for these items are the responsibilities of the Distributor
specifying the new package development of these "retail type" boxes. These
materials must be supplied in cooperation with the respective scheduling
department of the Manufacturer. Responsibility for the actual box itself and its
procurement will reside with the Manufacturer and will be included in the Landed
Duty Paid Price with respect to Distributor's purchases. Distributor
acknowledges receipt of minimum run per production process from Manufacturer for
non-stock items. These minimum quantities, including any subsequent
modifications, will be used as guidelines (but not the sole criteria) by
Manufacturer in rejecting orders from Distributor for production.

         Section 7.9 It is the intent of all parties to keep the packaging of
Specially Differentiated Products to a minimum. No more than 150 SKU's, on a
revolving basis, will be made in the United Mexican States and carry the brand
of a Libbey Party on the box. It is expected this program of differentiation
will be phased in over a one-year period, commencing on the date of this
Agreement.

         Section 7.10 Shipper carton markings, country of origin markings, and
appropriate languages to be reflected on the packaging will be the
responsibility of the Manufacturer. A close exchange and co-operative working
relationship between the new product development organization of the Distributor
and the new product development organization of the Manufacturer will be
absolutely necessary. It is expected that the Distributor will be very specific
in its requirements at the time of the order.

         Section 7.11 All specifications applicable to Glass Tableware supplied
hereunder, including, but not limited to, material, packaging, property,
dimensions, limit samples, esthetics, cosmetics, inspection, acceptance quality
limits, and acceptance samples will be agreed upon by the Manufacturer, the
Seller, and the Distributor at the time an order is accepted. Once established
for an item the specifications shall remain in effect until revised by mutual

<PAGE>   11



agreement. All Glass Tableware must meet all such specifications or may be
rejected by Distributor in which case the Distributor shall receive a full
refund or credit against the purchase price as the Distributor may elect, and
the product in question shall be returned to the Manufacturer at the
Manufacturer's expense or disposed of at the Manufacturer's expense.

         Section 7.12 In special situations where clearly identified in advance
at the time an order is accepted by the Manufacturer, Glass Tableware may be
ordered for a customer of the Distributor where timely, complete delivery of
Glass Tableware conforming to the specifications is required. In such cases, any
penalty paid by the Distributor for any failure to meet the requirements of the
order will be reimbursed by the Manufacturer unless such failure was not the
fault of the Manufacturer as set forth in ARTICLE IX.

         Section 7.13 Claims for breakage, shortages, overages, wrong-ware
shipped, and all other distribution related errors must be sent to the
Manufacturer by the Distributor within seven (7) days from the date of receipt
of shipment.

         Section 7.14 Claims for quality issues will be sent by the Distributor
to the Manufacturer on or before thirty (30) days following notification to the
Distributor from its customer of such issues. Resolution of such claims must be
within ninety (90) days of receipt by the Manufacturer of the quality claim.

         Section 7.15 Product liability claims and all associated legal costs
and any settlement costs will be the final responsibility of the Manufacturer.
The Manufacturer will defend and hold harmless at its expense the Distributor
from and against any and all cost, expense, and liability resulting from any
claim by a third party for bodily injury or damage to property alleging that any
Glass Tableware supplied hereunder is defective or fails to conform to the
specifications, from any claim by a governmental authority that the Glass
Tableware does not meet applicable legal requirements, and from any claim by a
governmental authority that Glass Tableware must be recalled due to a safety
condition or defect. The Manufacturer's obligations under this SECTION 7.15 are
subject to timely notice (unless failure to give timely notice does not
materially adversely affect the Manufacturer) and the right to control the
defense and settlement of the claim if so desired by the Manufacturer. The
Manufacturer's obligations under this SECTION 7.15 do not apply to any cost,
expense, or liability caused by the negligent or wrongful act or omission of the
Distributor; provided, however, the simple purchase and resale shall not be
deemed to be the negligent or wrongful act or omission of the Distributor.

         Section 7.16 Libbey Glass will work to maintain and perpetuate the
Crisa brand name in the United States of America in market niches such as floral
ware, tempered glass plates, and the "Impressions" line of tumblers and other
areas where in Libbey Glass's reasonable opinion the name has continued
strength.

                                  ARTICLE VIII
                 ADDITIONAL PRODUCTS OTHER THAN GLASS TABLEWARE

         Section 8.1 It is anticipated that by mutual agreement, from time to
time, the Libbey Parties and the Vitro Parties may authorize the other to
distribute additional products other than Glass Tableware in all or part of the
Territory. Such agreements with respect to products other than Glass Tableware
shall be on such terms and conditions as may be agreed upon by the parties at
the time, including, without limitation, pricing, products, territories,
duration, and terms and conditions of sale, all of which may be different or the
same as set forth herein and unless specifically otherwise agreed in writing
shall be subject to change and the agreement subject to termination, on written
notice from either Vitrocrisa or Libbey Glass to the other. All such agreements
shall be separate and distinct agreements from this Agreement and in no event
shall additional products other than Glass Tableware be subject to the
provisions of this Agreement.

                                   ARTICLE IX
                                  FORCE MAJEURE

         Section 9.1 Except for an obligation for the payment of money when due,
neither party shall be liable for any failure or delay in the performance of its
obligations under this Agreement when such failure or delay is caused by acts of
God, riot or civil commotion, strike, lockout or other labor disturbance, fire,
act or any order of government (whether or not valid), flood, war, peril of sea,
breakdown of machinery, delay in supply and/or transit of materials, components,
parts or assemblies from suppliers or sub-contractors, or any other matter or
peril; provided, however, that in all cases such cause is beyond the reasonable
control of the party who failed or was delayed in performance and such party
could not have prevented the failure or delay through reasonable action and has
taken reasonable action to mitigate the effect of the delay or failure. With
respect to an obligation for the payment of money, if by any regulation or order
of an applicable governmental authority a party is precluded from transmitting a
payment due under or by reason of this Agreement, the party owing the payment
shall make the payment in accordance with its obligations hereunder if it places
the sum due to the credit of the party to whom the payment is due in a bank
located in the country of paying party or if it effects payment by some other
method then authorized by the applicable governmental authority.

                                    ARTICLE X
                             ENFORCEMENT; NON-WAIVER

         Section 10.1. The parties hereby acknowledge and agree that Libbey
Glass and Vitrocrisa would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with its specific
terms or otherwise is breached. Accordingly, the parties hereto agree that,
subject to the provisions of SECTION 11.14, Vitrocrisa and Libbey Glass shall be
entitled to an injunction or injunctions to prevent breaches of the provisions
of this Agreement and to enforce specifically this Agreement and the terms and
provisions hereof in any action instituted in any court of the United States of
America (or of any state thereof) or of the 

<PAGE>   13



United Mexican States having jurisdiction over Vitro, in addition to any other
remedy to which Libbey Glass or Vitrocrisa may be entitled, at law or in equity.

         Section 10.2 A failure by the Vitro Parties or the Libbey Parties to
exercise or enforce any right conferred upon them by this Agreement shall not be
deemed to be a waiver of any right or operate so as to bar the exercise or
enforcement thereof at any subsequent time or times and all express rights
granted to any Vitro Party and any Libbey Party hereunder shall be in addition
to any right that the Vitro Parties and the Libbey Parties may have under the
general law in respect of a breach hereof. No waiver by either the Vitro Parties
or the Libbey Parties of any condition or the breach of any term, covenant,
representation, warranty, or undertaking contained in this Agreement, whether by
conduct or otherwise, in any one or more instances shall be deemed to be or
construed as a further or continuing waiver of any such condition or breach or a
waiver of any other condition or deemed to be or construed as a waiver of the
breach of any other term, covenant, representation, warranty, or undertaking
contained in this Agreement.

                                   ARTICLE XI
                                  MISCELLANEOUS

         Section 11.1 GOVERNING LANGUAGE. Notwithstanding the translation of
this Agreement or any of its Schedules or Exhibits into Spanish or any other

Schedules and Exhibits shall be controlling and shall govern in any legal
proceeding or arbitration.

         Section 11.2 COMMUNICATIONS. All correspondence, information,
specifications, reports, notices, and other written or oral communications
between the parties with respect to this Agreement and the transactions
contemplated hereunder shall be in the English language.

         Section 11.3 NO THIRD-PARTY BENEFICIARIES. This Agreement shall not
confer any rights or remedies upon any person other than the parties and their
respective successors and permitted assigns.

         Section 11.4 ENTIRE AGREEMENT. This Agreement constitutes the entire
agreement among the parties related to the subject matter hereof and supersedes
any prior understandings, agreements, or representations by or among the
parties, written or oral, that may have related in any way to the subject matter
hereof.

         Section 11.5 SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon and inure to the benefit of the parties named herein and their respective
successors and permitted assigns.

         Section 11.6 ASSIGNMENT. No party may assign or otherwise transfer any
of its rights or obligations under this Agreement, by operation of law or
otherwise, without the prior written consent of the other parties, which consent
shall not be unreasonably withheld. Any purported or attempted assignment
contrary to the terms hereof shall be null and void and of no force or effect.
Notwithstanding the foregoing, Libbey Glass may permit its Affiliates to
purchase Glass Tableware from Vitrocrisa and distribute such Glass Tableware in
the Territory provided that 

<PAGE>   14



Libbey and Libbey Glass each shall be responsible to cause such Affiliates of
Libbey Glass to perform the obligations of Libbey Glass hereunder.

         Section 11.7 COUNTERPARTS. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original but all of which

         Section 11.12 SEVERABILITY. Any term or provision of this Agreement
that is invalid or unenforceable in any situation in any jurisdiction shall not

         Section 11.14     Arbitration.
                           -----------

         (a)      The parties to this Agreement shall exert good faith efforts
                  promptly to resolve any controversy or claim arising out of or
                  related to this Agreement or the breach thereof within fifteen
                  (15) days of receipt of notice by one party from another party
                  that such a controversy or claim exists. If the parties fail
                  to resolve such controversy or claim within such fifteen (15)
                  day period, they shall, unless otherwise provided in this
                  Agreement, give notice in writing to the Chief Executive
                  Officers of Libbey and Vitro (the "CEOS"), who will meet
                  within fifteen (15) days of receipt of such notice at a
                  mutually acceptable time and place to attempt to resolve any
                  such controversy or claim. Notwithstanding the foregoing, the
                  parties hereby agree that either party can seek injunctive
                  relief as contemplated by SECTION 10.1. In the event the CEOs
                  fail to meet or to resolve the controversy or claim arising
                  out of or related to this Agreement or the breach thereof
                  within such fifteen (15) day period, the controversy or claim
                  (other than business and operational decisions customarily
                  exercised by management in entities similar to Vitrocrisa and
                  Libbey Glass, which are to be resolved by the CEOs) shall be
                  settled by arbitration in accordance with the then existing
                  International Arbitration Rules of the American Arbitration
                  Association (the "AAA"), which shall commence upon one party
                  providing the other parties with a written demand for
                  arbitration (the "DEMAND FOR ARBITRATION"). The arbitrators
                  may determine the appropriate monetary damages for any breach
                  or other appropriate remedy, but may not cause this Agreement
                  to be terminated. Notwithstanding the foregoing, the parties
                  hereby agree that if either party seeks injunctive relief as
                  contemplated by SECTION 10.1 such party does not thereby waive
                  its rights to arbitration under this SECTION 11.14.

         (b)      The arbitral tribunal shall be composed of three arbitrators
                  with Libbey Glass and Vitrocrisa each appointing one
                  arbitrator. If either Libbey Glass or Vitrocrisa fails to
                  appoint an arbitrator within thirty (30) days after the date
                  the claimant's Demand for Arbitration is communicated to the
                  other party (hereinafter the "NOTIFICATION DATE"), the AAA
                  shall make such appointment. The two arbitrators thus
                  appointed shall attempt to agree upon the appointment of a
                  third arbitrator to serve as chairman of the arbitral
                  tribunal. If said two arbitrators fail to agree upon the
                  appointment of such third arbitrator within sixty (60) days
                  after the Notification Date, the AAA shall make such
                  appointment. The place of arbitration shall be Dallas, Texas,
                  United States of America. The arbitral proceeding shall be
                  conducted in the English language.

         (c)      To the extent that they may validly so agree, the parties
                  hereby exclude any right of appeal to any court in connection
                  with the arbitral award. Judgment upon the arbitral award may
                  be entered in any court having jurisdiction thereof or having
                  jurisdiction over any party or any party's assets.

         (d)      The validity of this SECTION 11.14 shall be governed by the
                  United Nations Convention on the Recognition and Enforcement
                  of Foreign Arbitral Awards or the Inter-American Convention on
                  International Commercial Arbitration, to which Mexico and the
                  United States of America have adhered.

         (e)      All costs of arbitration and enforcement thereof, including
                  reasonable attorney's fees and court costs, costs of expert
                  witnesses, transportation, lodging and meal costs of the
                  parties and witnesses, costs of transcript preparation, and
                  other reasonable and necessary direct and incidental costs
                  shall be apportioned to one or more of the parties by a
                  majority of the arbitrators as they deem appropriate. In the
                  event any party to this Agreement commences legal proceedings
                  to enforce the arbitral award, the expense of such litigation
                  (including reasonable attorneys' fees and costs of court)
                  shall be borne by the party or parties not prevailing therein.

         Section 11.15 SCHEDULES AND EXHIBITS. The Schedules and Exhibits
attached hereto and referenced herein constitute a part of this Agreement and
are specifically incorporated by reference herein.

         Section 5.8 The methodology of computing the amount to be paid by
Vitrocrisa to Libbey Glass pursuant to SECTIONS 5.1 (and SCHEDULE 2) and 5.2
(and SCHEDULE 3) to purchase Glass Tableware hereunder sets forth the intended
sharing of profits and margins among Vitrocrisa and Libbey Glass with respect to
Glass Tableware sold hereunder. If any change in the methodology of computing
such prices is required in order to comply with governmental regulations or
legal requirements and such change would have a material adverse economic effect
on either Vitrocrisa or Libbey Glass with respect to the profits and margins
intended to be shared hereunder, Vitrocrisa and Libbey Glass agree to negotiate
in good faith another methodology of computing such price to meet governmental
regulations and legal requirements 


<PAGE>   5



and to place Vitro and Libbey in the same relative economic position with
respect to the sharing of profits and margins as is intended by ARTICLE V.

                                   ARTICLE VI
                              PERFORMANCE STANDARD

         Section 6.1 Libbey Glass and Vitrocrisa agree to use their best efforts
to carry out the sales plans agreed upon in the annual operating budgets which
will derive from the broader guidelines of the ongoing three-year strategic
plans of Vitrocrisa, as such budgets and strategic plans may be approved by
extraordinary directors action of the board of directors of Vitrocrisa.

                                   ARTICLE VII
                              OPERATING PROCEDURES

         Section 7.1 Distributor shall maintain its own offices and places of
business and pay all of its own expenses in connection with the sale and
distribution of Glass Tableware under this Agreement, except as otherwise
provided herein.

         Section 7.2 Distributor is designated to serve customers in the
Territory. Any inquiries or orders for Manufacturer's brand of Glass Tableware
from customers outside of the Territory will be referred by Distributor to
Manufacturer.

         Section 7.3 Manufacturer shall furnish Distributor in connection with
the Glass Tableware to be distributed hereunder a reasonable number of catalogs
and existing sales literature which the Manufacturer may, from time to time,
have in connection with its own sales, but the Manufacturer shall not be
obligated to generate or create any catalogs or sales literature for
Distributor.

         Section 7.4 The relationship between the parties hereto shall be one of
independent contractors. Neither the Distributor nor the Manufacturer shall be
empowered to have any authority to act for the other, make any commitment on
behalf of the other, make any agreement on behalf of the other, make any payment
on behalf of the other, or otherwise obligate the other in any way. Neither
Distributor nor Manufacturer shall hold itself out as having any authority to
act in any way for the other unless otherwise specifically agreed in writing.

         Section 7.5 All Glass Tableware sold hereunder shall be transferred to
Distributor free and clear of all liens and encumbrances.

         Section 7.6 Manufacturer shall secure and apply all packaging for Glass
Tableware sold hereunder and unless otherwise agreed in writing with respect to
any particular transaction the prices charged for Glass Tableware shall be
deemed to include all packaging expenses.

         Section 7.7 Regular current stock items to be procured and imported
hereunder will be ordered at levels that correspond to a mutually agreed upon
level per SKU. Should the Distributor require quantities in excess of the agreed
threshold levels, a separate Make and Ship 

<PAGE>   6



order must be processed with specific quantities and release dates. Failure by
the Distributor to honor the Make and Ship order by the release date or within
thirty (30) days thereafter will result in shipment and invoicing of the full
order as originally specified.

         Section 7.8 In some cases Distributor may desire and request Specially
Differentiated Product to be created specifically for its customers in the
Territory, which new items are beyond the normal stock collection of the
Manufacturer. These will be private items and may require new molds and cartons.
Unless otherwise agreed, the cost of developing new molds and cartons is the
responsibility of the Distributor and will be invoiced to the Distributor at
actual out of pocket costs paid to third party vendors in arms length
transactions. Four-color photography, artwork separations, and final layout for
any retail packaging for these new items are the responsibilities of the
Distributor specifying the new package development of these "retail type" boxes.
These materials must be supplied in cooperation with the respective scheduling
department of the Manufacturer. The actual box itself, and its procurement, will
reside with the Manufacturer and will be included in the purchase price of the
Glass Tableware with respect to Distributor's purchases. These minimum
quantities, including any subsequent modifications, will be used as guidelines
(but not the sole criteria) by Manufacturer in rejecting order from Distributor
for production.

         Section 7.9 It is the intent of all parties to keep the packaging of
Specially Differentiated Products to a minimum. No more than 150 SKU's, on a
revolving basis, will be made in the United States and Canada and carry the
brand of a Vitro Party on the box. It is expected this program of
differentiation will be phased in over a one-year period, commencing on the date
of this Agreement. Distributor acknowledges receipt of minimum run per
production process from Manufacturer for non-stock items.

         Section 7.10 Shipper carton markings, country of origin markings, and
appropriate languages to be reflected on the packaging will be the
responsibility of the Manufacturer. A close exchange and co-operative working
relationship between the new product development organization of the Distributor
and the new product development organization of the Manufacturer will be
absolutely necessary. It is expected that the Distributor will be very specific
in its requirements at the time of the order.

         Section 7.11 All specifications applicable to Glass Tableware supplied
hereunder, including, but not limited to, material, packaging, property,
dimensions, limit samples, esthetics, cosmetics, inspection, acceptance quality
limits, and acceptance samples will be agreed upon by the Manufacturer and the
Distributor at the time an order is accepted. Once established for an item the
specifications shall remain in effect until revised by mutual agreement. All
Glass Tableware must meet all such specifications or may be rejected by
Distributor in which case the Distributor shall receive a full refund or credit
against the purchase price, as the Distributor may elect, and the product in
question shall be returned to the Manufacturer at the Manufacturer's expense or
disposed of at the Manufacturer's expense.

         Section 7.12 In special situations where clearly identified in advance
at the time an order is accepted by the Manufacturer, Glass Tableware may be
ordered for a customer of the 

<PAGE>   7



Distributor where timely, complete delivery of Glass Tableware conforming to the
specifications is required. In such cases, any penalty paid by the Distributor
for any failure to meet the requirements of the order will be reimbursed by the
Manufacturer unless such failure was not the fault of the Manufacturer as set
forth in ARTICLE IX.

         Section 7.13 Claims for breakage, shortages, overages, wrong-ware
shipped, and all other distribution related errors must be sent to the
Manufacturer by the Distributor within seven (7) days from the date of receipt
of shipment.

         Section 7.14 Claims for quality issues will be sent by the Distributor
to the Manufacturer on or before thirty (30) days following notification to the
Distributor from its customer of such issues. Resolution of such claims must be
within ninety (90) days of receipt by the Manufacturer of the quality claim.

         Section 7.15 Product liability claims and all associated legal costs
and any settlement costs will be the final responsibility of the Manufacturer.
The Manufacturer will defend and hold harmless at its expense the Distributor
from and against any and all cost, expense, and liability resulting from any
claim by a third party for bodily injury or damage to property alleging that any
Glass Tableware supplied hereunder is defective or fails to conform to the
specifications, from any claim by a governmental authority that the Glass
Tableware does not meet applicable legal requirements, and from any claim by a
governmental authority that Glass Tableware must be recalled due to a safety
condition or defect. The Manufacturer's obligations under this SECTION 7.15 is
subject to timely notice (unless failure to give timely notice does not
materially adversely affect the Manufacturer) and the right to control the
defense and settlement of the claim if so desired by the Manufacturer. The
Manufacturer's obligations under this SECTION 7.15 do not apply to any cost,
expense, or liability caused by the negligent or wrongful act or omission of the
Distributor; provided, however, the simple purchase and resale shall not be
deemed to be the negligent or wrongful act or omission of the Distributor.

                                  ARTICLE VIII
                 ADDITIONAL PRODUCTS OTHER THAN GLASS TABLEWARE

         Section 8.1 It is anticipated that by mutual agreement from time to
time the Libbey Parties and the Vitro Parties may authorize the other to
distribute additional products other than Glass Tableware in all or part of the
Territory. Such agreements with respect to products other than Glass Tableware
shall be on such terms and conditions as may be agreed upon by the parties at
the time, including, without limitation, pricing, products, territories,
duration, and terms and conditions of sale, all of which may be different or the
same as set forth herein and, unless specifically otherwise agreed in writing,
shall be subject to change and the agreement subject to termination on written
notice from either Vitrocrisa or Libbey Glass to the other. All such agreements
shall be separate and distinct agreements from this Agreement and in no event
shall additional products other than Glass Tableware be subject to the
provisions of this Agreement.

                                   ARTICLE IX
                                  FORCE MAJEURE

         Section 9.1 Except for an obligation for the payment of money when due,
neither party shall be liable for any failure or delay in the performance of its
obligations under this Agreement when such failure or delay is caused by as acts
of God, riot or civil commotion, strike, lockout or other labor disturbance,
fire, act or any order of government (whether or not valid), flood, war, peril
of sea, breakdown of machinery, delay in supply and/or transit of materials,
components, parts or assemblies from suppliers or sub-contractors, or any other
matter or peril provided that in all cases such cause is beyond the reasonable
control of the party who failed or was delayed in performance and such party
could not have prevented the failure or delay through reasonable action and has
taken reasonable action to mitigate the effect of the delay or failure. With
respect to an obligation for the payment of money, if by any regulation or order
of an applicable governmental authority a party is precluded from transmitting a
payment due under or by reason of this Agreement, the party owing the payment
shall make the payment in accordance with its obligations hereunder if it places
the sum due to the credit of the party to whom the payment is due in a bank
located in the country of paying party or if it effects payment by some other
method then authorized by the applicable governmental authority.

                                    ARTICLE X
                             ENFORCEMENT; NON-WAIVER

         Section 10.1 The parties hereby acknowledge and agree that Libbey Glass
and Vitrocrisa would be damaged irreparably in the event any of the provisions
of this Agreement are not performed in accordance with its specific terms or
otherwise is breached. Accordingly, the parties hereto agree that, subject to
the provisions of SECTION 11.14, Vitrocrisa and Libbey Glass shall be entitled
to an injunction or injunctions to prevent breaches of the provisions of this
Agreement and to enforce specifically this Agreement and the terms and
provisions hereof in any action instituted in any court of the United States of
America (or of any state thereof) or of the United Mexican States having
jurisdiction over Vitro, in addition to any other remedy to which Libbey Glass
or Vitrocrisa may be entitled, at law or in equity.

         Section 10.2 A failure by the Vitro Parties or Libbey Parties to
exercise or enforce any right conferred upon them by this Agreement shall not be
deemed to be a waiver of any right or operate so as to bar the exercise or
enforcement thereof at any subsequent time or times, and all express rights
granted to any Vitro Party and any Libbey Party hereunder shall be in addition
to any right that the Vitro Parties and the Libbey Parties may have under the
general law in respect of a breach hereof. No waiver by either the Vitro Parties
or the Libbey Parties of any condition or the breach of any term, covenant,
representation, warranty, or undertaking contained in this Agreement, whether by
conduct or otherwise, in any one or more instances shall be deemed to be or
construed as a further or continuing waiver of any such condition or breach or a
waiver of any other condition or deemed to be or construed as a waiver of the
breach of any other term, covenant, representation, warranty, or undertaking
contained in this Agreement.

         Section 11.12 SEVERABILITY. Any term or provision of this Agreement
that is invalid or unenforceable in any situation in any jurisdiction shall not
affect the validity or enforceability of the remaining terms and provisions

court of competent jurisdiction declares that any term or provision hereof is
invalid or unenforceable, the parties agree that the court making the
determination of invalidity or unenforceability shall have the power to reduce
the scope, duration, or area of the term or provision, to delete specific words
or phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to

this Agreement shall be enforceable as so modified after the expiration of the
time within which the judgment may be appealed.

         Section 11.13 NO VIOLATION OF LAW. Any obligation of any party hereto
is subject to the approval of all applicable governmental authorities,

require any party to disclose to the other any information, to take any action
or refrain from taking any action or remain in any situation in violation of any
law or regulation, rule or requirement of any applicable governmental authority
to which such party is subject. Subject to the foregoing, in performing its
distribution functions hereunder, Vitrocrisa agrees to use reasonable efforts,
and to cause its customers to use reasonable efforts, to furnish such
information and do such acts to enable Libbey Glass to comply with any
requirement, restriction, or condition imposed upon any export out of the
country of manufacture or upon Libbey Glass by any applicable governmental
authority of the United States, and Libbey Glass agrees to use reasonable
efforts, and to cause its suppliers to use reasonable efforts, to furnish such
information and do such acts to enable Vitrocrisa to comply with any
requirement, restriction, or condition imposed upon any import into the
Territory or upon Vitrocrisa by any applicable governmental authority.

         Section 11.14     Arbitration.
                           -----------

                  (a) The parties to this Agreement shall exert good faith
efforts promptly to resolve any controversy or claim arising out of or related
to this Agreement or the breach thereof within fifteen (15) days of receipt of
notice by one party from another party that such a controversy or claim exists.
If the parties fail to resolve such controversy or claim within such fifteen
(15) day period, they shall, unless otherwise provided in this Agreement, give
notice in writing to the Chief Executive Officers of Libbey and Vitro (the
"CEOs"), who will meet within fifteen (15) days of receipt of such notice at a
mutually acceptable time and place to attempt to resolve any such controversy or
claim. Notwithstanding the foregoing, the parties hereby agree that either party
can seek injunctive relief as contemplated by SECTION 10.1. In the event the
CEOs fail to meet or to resolve the controversy or claim arising out of or
related to this Agreement or the breach thereof within such fifteen (15) day
period, the controversy or claim (other than business and operational decisions
customarily exercised by management in entities similar to Vitrocrisa and Libbey
Glass, which are to be resolved by the CEOs) shall be settled by arbitration in
accordance with the then existing International Arbitration Rules of the
American 

<PAGE>   12



Arbitration Association (the "AAA"), which shall commence upon one party
providing the other parties with a written demand for arbitration (the "DEMAND
FOR ARBITRATION"). The arbitrators may determine the appropriate monetary
damages for any breach or other appropriate remedy, but may not cause this
Agreement to be terminated. Notwithstanding the foregoing, the parties hereby
agree that if either party seeks injunctive relief as contemplated by SECTION
10.1, such party does not thereby waive its rights to arbitration under this
SECTION 11.14.

                  (b) The arbitral tribunal shall be composed of three
arbitrators and Libbey Glass and Vitrocrisa shall each appoint one Arbitrator.
If either Libbey Glass or Vitrocrisa fails to appoint an arbitrator within
thirty (30) days after the date the claimant's Demand for Arbitration is
communicated to the other party (the "NOTIFICATION DATE"), the AAA shall make
such appointment. The two arbitrators thus appointed shall attempt to agree upon
the appointment of a third arbitrator to serve as chairman of the arbitral
tribunal. If said two arbitrators fail to agree upon the appointment of such
third arbitrator within sixty (60) days after the Notification Date, the AAA
shall make such appointment. The place of arbitration shall be Dallas, Texas,
United States of America. The arbitral proceeding shall be conducted in the
English language.

                  (c) To the extent that they may validly so agree, the parties
hereby exclude any right of appeal to any court in connection with the arbitral
award. Judgment upon the arbitral award may be entered in any court having
jurisdiction thereof or having jurisdiction over any party or any party's
assets.

                  (d) The validity of this SECTION 11.14 shall be governed by
the United Nations Convention on the Recognition and Enforcement of Foreign
Arbitral Awards or the InterAmerican Convention on International Commercial
Arbitration, to which Mexico and the United States of America have adhered.

                  (e) All costs of arbitration and enforcement thereof,
including reasonable attorney's fees and court costs, costs of expert witnesses,
transportation, lodging and meal costs of the parties and witnesses, costs of
transcript preparation, and other reasonable and necessary direct and incidental
costs shall be apportioned to one or more of the parties by a majority of the
arbitrators as they deem appropriate. In the event any party to this Agreement
commences legal proceedings to enforce the arbitral award, the expense of such
litigation (including reasonable attorneys' fees and costs of court) shall be
borne by the party or parties not prevailing therein.

         Section 11.15 SCHEDULES AND EXHIBITS. The Schedules and Exhibits
attached hereto and referenced herein constitute a part of this Agreement and
are specifically incorporated by reference herein.

                  (xvii)   The establishment of compensation or policies
                           therefor for management, including, but not limited
                           to, executive officers and key employees, except as
                           provided by SECTION 3.2(d)(x) above.

         Notwithstanding any provision of the foregoing to the contrary, to the
extent a contract or other agreement has previously been approved by
Extraordinary Directors Action, the subsequent expenditure pursuant to such
contract or other agreement need not be approved by Extraordinary Directors
Action. The amount in United States dollars to be attributed to any matter in
this SECTION 3.2(d) shall be determined, if necessary, by reference to the
exchange rate for the purchase of dollars, as announced by Banca Serfin, S.A.,
on the date of the Vitrocrisa Board's vote on such matter.

         (e) MEETINGS. The Vitrocrisa Board shall meet at least twice annually,
the first meeting being within thirty (30) days after year-end audited financial
statements have been delivered to all Members of the Vitrocrisa Board, but in no
event more than four (4) months after the end of each fiscal year, or more
frequently at the request of any Shareholder or any Member. Notice of each
meeting of the Vitrocrisa Board shall be delivered to all Members at least
fifteen (15) days in advance of the date of such meeting. At least four (4)
Members of the Vitrocrisa Board or their alternates must be present to transact
business. Each meeting of the Vitrocrisa Board shall take place at 10:00 a.m. on
the fifteenth (15th) day after notice has been delivered to all Members, or at a
time and place mutually agreed upon by the Members. If Members sufficient to
transact business are not present at the meeting, the date of the meeting shall
be postponed for one (1) day, and if Members sufficient to transact business are
not present at that meeting, the date of the meeting shall be postponed for an
additional day. If Members sufficient to transact business are not present at
that meeting, either Voting Shareholder shall have the right, but shall not be
obligated, to declare the occurrence of a Deadlock Event under SECTION 6.1
hereof.

         (f) WAIVER OF NOTICE; VOTING. The Members can waive the requirement of
the written call, and same will not be required, when all of the Members or
their alternates are present at the meeting. Except as otherwise provided
herein, all decisions of the Vitrocrisa Board shall require the approval of a
majority of its Members. All decisions of the Members on any matters requiring
their approval, consent, or action may be made by the Members in each of their
sole and absolute discretion.

         (g) ACTION WITHOUT MEETING. Whenever the Vitrocrisa Board is required
or permitted to take any action pursuant to a meeting of the Vitrocrisa Board,
such action may be taken without a meeting upon a written consent setting forth
the action so taken that is signed by each of the Members.

         3.3. INDEMNIFICATION OF THE VITROCRISA BOARD. Each Member shall be
indemnified by Vitrocrisa against all liability for any claim, demand, loss,
damage, liability, or expense (including, without limitation, amounts paid in
settlement, reasonable costs of investigation, and reasonable legal expenses)
resulting from any threatened, pending, or completed action, suit, or proceeding
naming any of them as defendant by reason of acts or omissions made or omitted
in good faith within the scope of their authority as set forth in this Agreement
to the maximum extent permitted by law.

         3.4. TRANSACTIONS WITH SHAREHOLDERS OR THEIR AFFILIATES. Vitrocrisa may
enter into contracts and agreements with a Shareholder or its affiliates in the
ordinary course of business, provided, however, that any contract or agreement
not in the ordinary course of business must be approved by Extraordinary
Directors Action.

         3.5. MANAGEMENT AND ADMINISTRATIVE SERVICE AGREEMENTS WITH VITRO AND
LIBBEY. The Vitrocrisa Board shall cause Vitrocrisa to enter into a Management
and Administrative Service Agreement with each of Vitro and Libbey,
substantially in the form of EXHIBIT G-1 and EXHIBIT G 2. The aggregate annual
fees to be paid to Vitro in connection with the Management and Administrative
Service Agreement will initially be equal to 1-1/2% of the gross sales of
Vitrocrisa, and the aggregate annual fees to be paid to Libbey in connection
with the Management and Administrative Service Agreement will initially be
US$1,000,000.

         3.6. CORPORATE GUARANTEES. The Shareholders hereby agree that any
Shareholder may charge and collect from Vitrocrisa monthly a fee for all
Vitrocrisa loans guaranteed by such Shareholder in an amount equal to 1-1/2% per
annum of the average daily balances of such loans.

         3.7. CORPORATE OPPORTUNITY. No person or entity of the Libbey 100%
Group (as defined in ARTICLE IV) and no person or entity of the Vitro 100% Group
(as defined in ARTICLE IV) has any duty to communicate or offer any Corporate
Opportunity (as defined below) to Vitrocrisa, and neither the Libbey 100% Group
nor the Vitro 100% Group shall be liable to Vitrocrisa or any Shareholder for
breach of any fiduciary duty or duty of loyalty to Vitrocrisa by reason of the
fact that it pursues or acquires a Corporate Opportunity for itself or directs a
Corporate Opportunity to another person or entity. For purposes of this section,
"CORPORATE OPPORTUNITY" means a business or other opportunity that Vitrocrisa is
or could reasonably be expected to become financially able to undertake, which
relates to Vitrocrisa's line of business and in which Vitrocrisa has or would
have an interest or a reasonable expectancy of interest. To the extent this
SECTION 3.7 contradicts any term or provision in the Distribution Agreement,
dated of even date, by and among Vitro, Vitrocrisa, Libbey, and Libbey Glass
Inc., the Distribution Agreement, dated of even date, by and among Vitro, Crisa
Corporation, Vitrocrisa, Libbey, and Libbey Glass Inc. (together, the
"DISTRIBUTION AGREEMENTS"), or the Covenant Not to Compete, dated of even date,
by and between Libbey and Vitro (the "COVENANT NOT TO COMPETE"), the terms and
provisions of the Distribution Agreements or the Covenant Not to Compete shall
control.

         (a) TRANSFERS. No Shareholder shall transfer all or any portion of its
interest in Vitrocrisa or its rights under this Agreement, or agree to do so,

foregoing, no Shareholder may transfer all or any portion of its interest in
Vitrocrisa or its rights under this Agreement, or agree to do so, for a period
of four 


                                      -9-
<PAGE>   10



(4) years from the date of this Agreement. After such four-year period, any
Shareholder may transfer all, but not less than all, of its interest in
Vitrocrisa pursuant to the terms of SECTION 4.2. A Shareholder may transfer or
otherwise sell its shares pursuant to this ARTICLE IV for any reason.

         (b) ENCUMBRANCE. Except as otherwise provided in this Agreement, no
Shareholder may encumber, mortgage, pledge, hypothecate, or place a lien or make
any disposition similar thereto (collectively an "ENCUMBRANCE") upon all or any
portion of its interest in Vitrocrisa or its rights under this Agreement, or
agree to do so, without the prior written consent of the other Shareholder,
which consent shall not be unreasonably withheld but may be subject to such
reasonable conditions as Libbey and Vitro may require.

         (c) VIOLATION. Any purported transfer or Encumbrance in violation of
the terms of this Agreement shall be null and void and shall not be recognized
by Vitrocrisa.

         (b) LIMITATION ON TRANSFERS. The right to transfer or dispose of shares
of Vitrocrisa or any interest therein shall (save in respect of transfers made
pursuant to SECTION 4.2(i) hereof) be subject to the restrictions set forth in
this SECTION 4.2. A Voting Shareholder may not transfer or dispose of its shares
in Vitrocrisa unless it transfers or disposes of all of its Joint Venture
Interest. Except as provided otherwise herein, no Voting Shareholder may
transfer or dispose of its Joint Venture Interest (save in respect of transfers
made pursuant to SECTION 4.2(i)) without the prior written consent of the other
Voting Shareholder.

         (c) FIRST OPTION. Before transferring or disposing of its Joint Venture
Interest (or any interest therein), the Proposing Transferor shall serve a
Transfer Notice on the other Voting Shareholder stipulating the Prescribed
Price. Upon receipt of a Transfer Notice, the other Voting Shareholder shall
have the right and first option for a period of thirty (30) days to purchase the
Joint Venture Interest at the Prescribed Price.

         (d) TRANSFER ON EXERCISE OF OPTION. If the Proposing Transferor is
given notice under SECTION 4.2(c) that the other Voting Shareholder has
exercised its option to purchase all, but not less than all, of the Joint
Venture Interest, the Proposing Transferor shall be bound, on payment of the
Prescribed Price, to transfer the Joint Venture Interest to the Purchaser or its
designees. The sale and purchase shall be completed at the office of Vitrocrisa,
or at such other place as the Proposing Transferor and the other Voting
Shareholder shall agree, during normal business hours on the first business day
after the expiration of ninety (90) days after the expiration of the option
period set forth in SECTION 4.2(c).

         (e) TRANSFER ON EXPIRATION OR TERMINATION OF OPTION. If the option
granted by SECTION 4.2(c) is not exercised as to all of the Joint Venture
Interest, then such option shall become void AB INITIO and the Proposing
Transferor may sell all of the Joint Venture Interest to any third party free of
the restrictions set forth in this ARTICLE IV, subject to the following
restrictions: (i) the Joint Venture Interest may not be sold after the
expiration of one hundred eighty (180) days after the expiration of the option
period set forth in SECTION 4.2(c), (ii) the Joint Venture Interest must be sold
in a bona fide sale at a price not being less that the Prescribed Price, and
(iii) the third party 


                                      -11-
<PAGE>   12



transferee of the Joint Venture Interest must execute and deliver an undertaking
under which such third party shall become a party hereto, to the Vitrocrisa
Holding, S.A. de C.V. Shareholders Agreement dated of even date (the "VC HOLDING
SHAREHOLDERS AGREEMENT"), to the Crisa Libbey, S.A. de C.V. Shareholders
Agreement dated of even date (the "NEWCO FINANCE SHAREHOLDERS AGREEMENT"), and
to the Limited Liability Company Agreement of Crisa Industrial, L.L.C. dated of
even date (the "LLC AGREEMENT," and collectively with this Agreement, the VC
Holding Shareholders Agreement, and the Newco Finance Shareholders Agreement,
the "JOINT VENTURE SHAREHOLDERS AGREEMENTS") in place of the Proposing
Transferor.

         (f) EXERCISE. An option granted by SECTION 4.2(c) may be exercised only
by the holder thereof and only by the delivery of a written notice of exercise
to the Proposing Transferor prior to the expiration of the relevant option
period.

         (g) WAIVER. The restrictions imposed by this ARTICLE IV may be waived
in relation to any proposed transfer of a Voting Shareholder's Joint Venture
Interest with the consent of all Shareholders who would otherwise have been
entitled to have such Joint Venture Interest offered to them in accordance
herewith.

         (h) FAILURE TO TIMELY EXERCISE. Failure of a Voting Shareholder to
exercise an option granted by SECTION 4.2(C) prior to the expiration of the
option period shall be deemed to be a waiver of that option as of the date the
option period expired. The waiver of an option granted by SECTION 4.2(c) will
not constitute a waiver of any subsequent option granted by SECTION 4.2(c).

         (i) INTRA-GROUP TRANSFERS. Notwithstanding the foregoing, all, but not
less than all, of a Voting Shareholder's Joint Venture Interest may be
collectively transferred to any member of the Vitro 100% Group (in the case of
Vitro) and to any member of the Libbey 100% Group (in the case of LGA3), but
only (i) if the transferee is already a party to each of the Joint Venture
Shareholders Agreements or shall have first agreed to adhere to and be bound by
the provisions of each of the Joint Venture Shareholders Agreements by executing
and delivering in favor of the other parties to each of the Joint Venture
Shareholders Agreements an undertaking to the intent and with the effect that
from the date of such undertaking, or, if later, the date of the transfer, the
transferee shall become a party to each of the Joint Venture Shareholders
Agreements, in place of the transferor, to the extent that the transferor ceases
to hold shares in Vitrocrisa, VC Holding, Newco Finance, and the LLC as a result
of such transfer; and (ii) on terms that the transferee shall re-transfer the
relative Joint Venture Interest to a member of the Vitro 100% Group (in the case
of Vitro) or to a member of the Libbey 100% Group (in the case of LGA3) on the
same terms as set forth in this SECTION 4.2(i), prior to such transferee ceasing
to be a member of the Vitro 100% Group or the Libbey 100% Group (as the case may
be).

         (j) OPTION TO PARTICIPATE IN SALE. In lieu of exercising the option
granted in SECTION 4.2(c), a Voting Shareholder may elect to participate in any
sale by the Proposing Transferor contemplated by SECTION 4.2 at the Prescribed
Price. Upon such election, the Voting Shareholder will be entitled to sell all,
but not less than all, of its Joint Venture Interest. The election to
participate in a sale must be in writing and must be delivered to the selling
Shareholder within thirty (30) days of receipt of the Transfer Notice. Failure
to timely deliver a written election 


                                      -12-
<PAGE>   13


to participate in a sale within thirty (30) days of the Transfer Notice will
constitute a waiver of such Voting Shareholder's right to participate in the
sale.

                                    ---------

         (c)      by decree of a court of competent jurisdiction; or

         (d)      upon the merger of Vitrocrisa into VC Holding; provided,
                  however, that the parties agree that, upon the consummation of
                  such merger, the parties shall enter into a new agreement
                  having terms substantially similar to, and with the same
                  intent of, the terms of this Agreement.

         5.2. EVENTS OF DEFAULT. The occurrence of any of the following events
shall constitute an event of default ("EVENT OF DEFAULT") hereunder on the part
of the Shareholder with respect to whom such event occurs (the "DEFAULTING
PARTY") without any requirement of notice or passage of time except as
specifically set forth in any such subparagraph:

         (a)      the violation by a Shareholder of any of the restrictions set
                  forth in ARTICLE IV;

         (b)      failure of a Voting Shareholder's Member of the Vitrocrisa

         (g)      the appointment of a receiver, custodian, trustee, or like
                  officer, to take possession of the assets of a Shareholder or
                  Libbey if the pendency of said receivership would reasonably
                  tend to have a materially adverse effect upon the performance
                  by the Shareholder or Libbey, respectively, of its obligations
                  under this Agreement, which receivership remains undischarged
                  for a period of sixty (60) days from the date of its
                  imposition;

         (h)      attachment, execution, or other judicial seizure of all or any
                  substantial part of a Shareholder's or Libbey's assets or of a
                  Shareholder's or Libbey's shares of Vitrocrisa, or any part
                  thereof, such attachment, execution, or seizure remaining
                  undismissed or undischarged for a period of sixty (60) days
                  after the levy thereof, if the occurrence of such attachment,
                  execution, or other judicial seizure would reasonably tend to
                  have a materially adverse effect upon the performance by the
                  Shareholder or Libbey, respectively, of its obligations under
                  this Agreement; provided, however, that said attachment,
                  execution, or seizure shall not constitute an Event of Default
                  hereunder if the Shareholder or Libbey, respectively, posts a
                  bond sufficient to fully satisfy the amount of such claim or
                  judgment within sixty (60) days after the levy thereof and the
                  respective Shareholder's or Libbey's assets are thereby
                  released from the lien of such attachment;

         (i)      material default in performance of or a failure to comply with
                  any obligations or undertakings of a Shareholder or Libbey
                  under the Covenant Not to Compete dated of even date by and
                  between Vitro and Libbey, and such default continues for a
                  period of thirty (30) days following notice of such default by
                  another Shareholder;

         (j)      the occurrence of an Event of Default (as defined therein)
                  under ARTICLE V of the VC Holding Shareholders Agreement; and

         (k)      the occurrence of a Libbey Change of Control or a Vitro Change
                  of Control (both as defined in SECTION 5.6 below);

         (l)      during fiscal years 1998, 1999, and 2000, the wrongful failure
                  of a member of the Libbey 100% Group to maintain the rights of
                  Vitrocrisa to distribute Libbey Glass' glass tableware under
                  the Distribution Agreement (as defined in the Master
                  Investment Agreement) in which Vitrocrisa is the distributor;
                  provided, however, that an adjustment of the price to be paid
                  for the glass tableware to be purchased by the distributor in
                  accordance with the Distribution Agreement shall not
                  constitute an Event of Default;

         (m)      during fiscal years 1998, 1999, and 2000, the wrongful failure
                  of a member of the Vitro 100% Group to maintain the rights of
                  Libbey Glass to distribute Vitrocrisa's glass tableware under
                  the Distribution Agreement (as defined in the Master
                  Investment Agreement); provided, however, that an adjustment
                  of the price to be 



                                      -14-
<PAGE>   15


                  paid for the glass tableware to be purchased by the
                  distributor in accordance with the Distribution Agreement
                  shall not constitute an Event of Default;

         (n)      the inability, occurring on or before the third anniversary of
                  this Agreement, of Vitrocrisa's auditors to provide a clean
                  opinion on its financial statements pursuant to generally
                  accepted accounting principles of the United Mexican States
                  for any reason (other than due to the difference in standards
                  imposed by Mexican legislation) that could have a material
                  adverse effect on the proper recording of the financial
                  statements of Vitrocrisa;

         (o)      the violation, occurring on or before the third anniversary of
                  this Agreement, of the principles under the section titled
                  "Debt" set forth on EXHIBIT C;

         (p)      the violation, occurring on or before the third anniversary of
                  this Agreement, of the principles in the personnel policy
                  attached hereto as EXHIBIT F; and

         (q)      the failure, occurring on or before the third anniversary of
                  this Agreement, of Vitrocrisa to use reasonable efforts to
                  maintain the glass tableware production capacity as outlined
                  in the section titled "Glass Tableware Production Capacity"
                  set forth on EXHIBIT C.

         5.3. REMEDY ON DEFAULT. If an Event of Default is declared by a Voting
Shareholder pursuant to (a) SECTION 5.2(b), (b) SECTION 5.2(c) with respect to
dividends to be paid for the performance of Vitrocrisa during fiscal years 1998,
1999, or 2000, (c) SECTION 5.2(k) with respect to a Libbey Change of Control or
a Vitro Change of Control occurring on or before the third anniversary of this
Agreement, (d) SECTION 5.2(l), (e) SECTION 5.2(m), (f) SECTION 5.2(n), (g)
SECTION 5.2(o), (h) SECTION 5.2(P), or (i) SECTION 5.2(q), then such Voting
Shareholder may, in addition to any other remedy at law or in equity, invoke the
provisions of SECTION 5.5. If an Event of Default is declared at any time (a) by
a Voting Shareholder pursuant to SECTIONS 5.2(a), (d), (e), (f), (g), (h), (i),
or (j), or (b) by any party to this Agreement pursuant to SECTION 5.2(c) with
respect to dividends to be paid for the performance of Vitrocrisa after fiscal
year 2000, or (c) by a Voting Shareholder pursuant to SECTION 5.2(k) with
respect to a Libbey Change of Control or a Vitro Change of Control occurring
after the third anniversary of this Agreement, then such Voting Shareholder may,
in addition to any other remedy at law or in equity, invoke the provisions of
SECTION 5.4.

         5.4. BUY/SELL PROVISION. Within forty-five (45) days of an Event of
Default, the non-defaulting party (the "OFFERING SHAREHOLDER") may deliver a
written offer (the "OFFER") to purchase all, but not less than all, of the other
Voting Shareholder's Joint Venture Interest at a cash purchase price (the "OFFER
PRICE"), fully payable on or before sixty (60) days after notice of the Offer.
Within thirty (30) days after receipt of the Offer, the other Voting Shareholder
may notify the Offering Shareholder in writing that it will either (i) sell to
the Offering Shareholder all, but not less than all, of its Joint Venture
Interest at the Offer Price, on or before the sixtieth day after receipt of the
Offer or (ii) buy from the Offering Shareholder all, but not less than all, of
the Offering Shareholder's Joint Venture Interest at (A) if Vitro is the
Offering Shareholder, 51/49 of the Offer Price or (B) if LGA3 is the Offering
Shareholder, 49/51 of the Offer Price (the "ADJUSTED OFFER Price"), on or 



                                      -15-
<PAGE>   16



before the sixtieth day after receipt of the Offer. If the other Voting
Shareholder fails to notify the Offering Shareholder within the thirty (30) day
period that it will (i) sell all of its Joint Venture Interest to the Offering
Shareholder at the Offer Price or (ii) buy all of the Joint Venture Interest
from the Offering Shareholder at the Adjusted Offer Price, then the Offering
Shareholder must purchase in cash all, but not less than all, of the other
Voting Shareholder's Joint Venture Interest at the Offer Price and the other
Voting Shareholder must sell all, but not less than all, of its Joint Venture
Interest at the Offer Price, on or before the sixtieth day after notice of the
Offer. Upon the purchase or sale of shares pursuant to this SECTION 5.4, this
Agreement and the VC Holding Shareholders Agreement shall automatically
terminate without further action by either Voting Shareholder. Failure by the
non-defaulting party to deliver an Offer within forty-five (45) days of notice
of an Event of Default shall constitute a waiver of such party's rights under
this SECTION 5.4 with respect to the particular Event of Default.

         5.5.     Dispute Resolution; Put/Call Option.
                  ------------------------------------

         (a) DISPUTE RESOLUTION. If an Event of Default is declared by a Voting
Shareholder pursuant to (i) SECTION 5.2(B), (ii) SECTION 5.2(c) with respect to
dividends to be paid for the performance of Vitrocrisa during fiscal years 1998,
1999, or 2000, (iii) SECTION 5.2(k) with respect to a Libbey Change of Control
or a Vitro Change of Control occurring on or before the third anniversary of
this Agreement, (iv) SECTION 5.2(l), (v) SECTION 5.2(m), (vi) SECTION 5.2(n),
(vii) SECTION 5.2(o), (viii) SECTION 5.2(p), or (ix) SECTION 5.2(q), such Voting
Shareholder shall promptly (but in no event later than thirty (30) days after
such Voting Shareholder's knowledge of such Event of Default) send notice of
such Event of Default to the other Voting Shareholder (the "DEFAULT NOTICE").
Upon receipt of the Default Notice, the alleged defaulting party will have
thirty (30) days to cure such default. If the default is not cured within such
thirty (30) day period or if the party receiving the Default Notice contests
that a default has occurred, the chief executive officers of Libbey and Vitro
(collectively, the "CEOS") shall meet within ninety (90) days of the expiration
of the cure period in a good faith effort to resolve the Event of Default. If
the Event of Default is not resolved within such ninety (90) day period, the
CEOs may select an independent mediator and subject the dispute to non-binding
mediation, which must take place within thirty (30) days of the expiration of
such ninety (90) day period. If both CEOs do not consent to non-binding
mediation or if the mediation fails to resolve the Event of Default, the Event
of Default shall be submitted to binding arbitration to be conducted in
accordance with the provisions of SECTION 8.10(b), (c), (d), and (e), the sole
purpose of which is to decide whether a default exists and, if so, which Voting
Shareholder is in default. The arbitrators will consider all issues currently in
dispute between the Voting Shareholders and must certify their ruling in writing
to each Voting Shareholder (the date of such certification is referred to herein
as the "CERTIFICATION DATE"). If the arbitrators determine and certify that one
Voting Shareholder is in default, then such Voting Shareholder shall have thirty
(30) days from the Certification Date to cure the default. If the Event of
Default is not cured within such thirty (30) day period, the non-defaulting
party may invoke the provisions of SECTION 5.5(b). If the arbitrators cannot
resolve which party has caused the Event of Default or determine that both
Voting Shareholders have caused the Event of Default and so certify, then either
of the Voting Shareholders may invoke the provisions of SECTION 5.4 within
thirty (30) days of the Certification Date.

         (b)      Put/Call Option With Penalty.
                  -----------------------------

                  (i) PUT/CALL OPTION WITH PENALTY. If the arbitrators determine
         that Vitro or any member of the Vitro 100% Group is in default and such
         default shall not be cured within thirty (30) days of the Certification
         Date, then Libbey shall have the right to sell to Vitro, and Vitro
         shall be obligated to purchase from Libbey, all, but not less than all,
         of Libbey's Joint Venture Interest at forty-nine percent (49%) of the
         Joint Venture Value (as defined below) multiplied by one hundred twenty
         percent (120%) (the "PUT OPTION"). If the arbitrators determine that
         Libbey or any member of the Libbey 100% Group is in default, then Vitro
         shall have the right to buy from Libbey, and Libbey shall be obligated
         to sell to Vitro, all, but not less than all, of Libbey's Joint Venture
         Interest at forty-nine percent (49%) of the Joint Venture Value (as
         defined below) multiplied by eighty percent (80%) (the "CALL Option").
         The Put Option and the Call Option are collectively referred to herein
         as the "OPTION."

                  (ii) VALUATION OF THE JOINT VENTURE. If the party in default
         does not cure the Event of Default within thirty (30) days of the
         Certification Date, the non-defaulting party may request a valuation of
         the joint venture as a going concern, which will include a valuation of
         the combined businesses of Vitrocrisa, VC Holding, Newco Finance, and
         the LLC (collectively, the "JOINT VENTURE"), within thirty (30) days of
         the expiration of the cure period. Within thirty (30) days of the date
         of such request, the CEOs will meet, and each CEO will select one
         investment banker, and the two selected investment bankers will then
         select a third investment banker, for the purpose of establishing a
         value for the Joint Venture as a going concern. Upon selection, each of
         the three investment bankers will independently determine the value for
         the Joint Venture as a going concern, the average of which will be
         deemed to be the joint venture value (the "JOINT VENTURE VALUE").

                  (iii) EXERCISING OPTION. The non-defaulting party may exercise
         the Option by giving the defaulting party written notice of its intent
         to exercise the Option within thirty (30) days of the date that the
         Joint Venture Value is determined by the investment bankers.

                  (iv) CLOSING OF OPTION. The closing of the Option will take
         place at a time and place mutually agreed upon by Libbey and Vitro;
         provided, however, that in no event will the closing take place more
         than sixty (60) days from the date of the notice of exercise set forth
         in SECTION 5.5(b)(iii).

                  (v) INVESTMENT BANKER FEES. Fees and expenses incurred in
         connection with the determination of the Joint Venture Value,
         including, without limitation, investment banker fees, will be paid by
         the party in default as certified by the arbitrators; provided,
         however, that all such fees and expenses will be paid by the
         non-defaulting party if the non-defaulting party fails to exercise the
         Option.

         5.6. DEFINITION OF CHANGE OF CONTROL. In this ARTICLE V, the following
words shall bear the following meanings:



                                      -17-
<PAGE>   18



         (a) "LIBBEY CHANGE OF CONTROL" shall be deemed to have occurred when
(i) any person or entity, together with any group of controlled companies not in
the Libbey 100% Group, acquires beneficial ownership, directly or indirectly, of
shares of stock of Libbey entitling such person or entity to exercise more than
50% of the total voting power of all classes of stock of Libbey entitled to vote
in elections of directors, or (ii) Libbey sells, leases or otherwise transfers
all or substantially all of its assets to any person or entity not in the Libbey
100% Group.

         (b) "VITRO CHANGE OF CONTROL" shall be deemed to have occurred when (i)
any person or entity, together with any group of controlled companies not in the
Vitro 100% Group, acquires beneficial ownership, directly or indirectly, of
shares of stock of Vitro entitling such person or entity to exercise more than
50% of the total voting power of all classes of stock of Vitro entitled to vote
in elections of directors, or (ii) Vitro sells, leases or otherwise transfers
all or substantially all of its assets to any person or entity not in the Vitro
100% Group.

                                   ARTICLE VI
                                   ----------

                              Deadlock and Impasse
                              --------------------

         6.1. DEADLOCK. A "DEADLOCK EVENT" shall be deemed to occur at such time
as a Voting Shareholder (the "NOTIFYING SHAREHOLDER") delivers to the other
Voting Shareholder a notification in writing (the "DEADLOCK NOTICE") stating
that, in the opinion of the Notifying Shareholder, (a) the other Voting
Shareholder's chief executive officer ("CEO") failed to meet with the Notifying
Shareholder's CEO to resolve a controversy or claim regarding a business and
operational decision customarily exercised by the management of Vitrocrisa
within the time limits set forth in SECTION 8.10(a), (b) the other Voting
Shareholder has, or the other Voting Shareholder's Members of the Vitrocrisa
Board have, deliberately prevented the occurrence of a quorum as set forth in
SECTION 3.1 or SECTION 3.2(e), respectively, or (c) the Voting Shareholders or
the Vitrocrisa Board are unable to reach agreement on any of the actions set
forth in SECTION 3.1(a), (b), or (c) or SECTION 3.2(d), respectively, and
setting out the reasons therefor, and there is no resolution or agreement that
has been approved by both Voting Shareholders (which approval may be given or
withheld, or made subject to such conditions, as are determined by the Voting
Shareholders in their respective sole and absolute discretion) within seven (7)
days after delivery of the Deadlock Notice. A Deadlock Event shall be resolved
in accordance with the provisions of this ARTICLE VI.

         6.2. RESOLUTION OF DEADLOCK. In the event of a Deadlock Event, either
Voting Shareholder may deliver notice of a meeting of the Shareholders (an
"EMERGENCY NOTICE") to the other Voting Shareholder, and they shall immediately
meet at a time and place mutually agreed upon or, if no time and place is
agreeable, at Vitrocrisa's principal place of business at 10:00 a.m. on the
fifteenth (15th) day after the date of such Emergency Notice. Notwithstanding
anything in this Agreement to the contrary, if either Voting Shareholder does
not attend such meeting, either Voting Shareholder may immediately invoke the
provisions of SECTION 6.4.

         6.3. DECLARATION OF IMPASSE. If, at the meeting contemplated in SECTION
6.2, the Voting Shareholders are unable to agree on a course of action to
address the reason for the meeting, any Voting Shareholder may declare an
impasse ("IMPASSE") by giving written notice to the other Voting Shareholder (an
"IMPASSE NOTICE"). Within twenty (20) days after receipt of such Impasse 


                                      -18-
<PAGE>   19



Notice, the CEOs shall meet in a good faith effort to reach accords that will
end the Impasse. If a decision is not made by common accord that ends the
Impasse within thirty (30) days after the date that the CEOs meet, either Voting
Shareholder may declare a final Impasse ("FINAL IMPASSE") by written notice to
the other Voting Shareholder. Notwithstanding anything in this Agreement to the
contrary, if either CEO refuses to meet with the other CEO, either Voting
Shareholder may immediately invoke the provisions of SECTION 6.4.

         6.4. FINAL IMPASSE. Within forty-five (45) days of notice of Final
Impasse (or pursuant to the provisions of SECTION 2.3 or of SECTIONS 6.2 or
6.3), either Voting Shareholder (the "OFFERING SHAREHOLDER") may deliver a
written Offer to purchase all, but not less than all, of the Joint Venture
Interest held by the other Voting Shareholder at a cash Offer Price, fully
payable on or before sixty (60) days after notice of the Offer. Within thirty
(30) days after receipt of the Offer, the other Voting Shareholder may notify
the Offering Shareholder in writing that it will either (a) sell to the Offering
Shareholder all, but not less than all, of its Joint Venture Interest at the
Offer Price on or before the sixtieth day after receipt of the Offer or (b) buy
from the Offering Shareholder all, but not less than all, of the Offering
Shareholder's Joint Venture Interest at the Adjusted Offer Price on or before
the sixtieth day after receipt of the Offer. If the other Voting Shareholder
fails to notify the Offering Shareholder within the thirty (30) day period that
it will (a) sell all of its Joint Venture Interest to the Offering Shareholder
at the Offer Price or (b) buy all of the Joint Venture Interest from the
Offering Shareholder at the Adjusted Offer Price, then the Offering Shareholder
must purchase in cash all, but not less than all, of the other Voting
Shareholder's Joint Venture Interest at the Offer Price and the other Voting
Shareholder must sell all, but not less than all, of its Joint Venture Interest
at the Offer Price, on or before the sixtieth day after notice of the Offer.
Upon the purchase or sale of shares pursuant to this SECTION 6.4, this Agreement
and the VC Holding Shareholders Agreement shall automatically terminate without
further action. Failure by either Voting Shareholder to deliver an Offer within
forty-five (45) days of notice of a Final Impasse shall constitute a waiver of
each Voting Shareholder's rights under this SECTION 6.4 with respect to the
particular Final Impasse.

                                   ARTICLE VII
                                   -----------

                     Annual Operating Budgets for Vitrocrisa
                     ---------------------------------------

         7.1. SUBMISSION OF ANNUAL OPERATING BUDGET. At least forty-five (45)
days prior to the end of the calendar year beginning with November 16, 1997, the
Managing Director of Vitrocrisa shall prepare a report on Vitrocrisa's working
capital requirements and operating budget for the succeeding calendar year,
which will substantially contain an estimate or projection of (a) working
capital requirements, including a breakout of accounts receivable, inventory,
and accounts payable, (b) sources of revenue (by geographic area, ware type,
trade areas, or established areas of distribution), (c) the cost of goods sold,
(d) selling, general, and administrative expense detail, (e) interest expense,
(f) an income statement, balance sheet, and statement of cash flows, all on a
quarterly basis, (g) funding requirements, capital expenditures, and repairs and
maintenance expense, (h) manufacturing objectives, including yield objectives by
ware type and planned capacity, (i) distribution objectives, (j) information
technology objectives, (k) engineering objectives, (l) sales plan, (m) marketing
plan, including marketing programs, (n) finance goals, (o) general

                                      -19-
<PAGE>   20



undertaken by Vitrocrisa for such year (the "PROPOSED BUDGET"). Upon preparation
of the Proposed Budget, the Managing Director shall promptly submit the Proposed
Budget to the Vitrocrisa Board for consideration.

         7.2. PREPARATION OF THREE-YEAR STRATEGIC PLAN. In addition to the
annual preparation of the Proposed Budget, the Managing Director shall prepare a
strategic plan for the next succeeding three fiscal years (the "THREE-YEAR
STRATEGIC PLAN"), which shall substantially contain the three-year estimates or
projections of the following items for Vitrocrisa: (a) working capital
requirements, including accounts receivable, inventory, and accounts payable,
(b) sources of revenue (by geographic area, ware type, trade areas, etc.), (c)
selling, general, and administrative expense detail, (d) interest income and
interest expense, (e) repairs and maintenance expense, (f) capital expenditures,

including marketing programs, (m) finance goals, (n) general administrative
goals, and (o) income statement, balance sheet, and statements of cash flow. The
Managing Director shall distribute the Three-Year Strategic Plan to the
Vitrocrisa Board along with the Proposed Budget.

         7.3. APPROVAL OF ANNUAL OPERATING BUDGET. Promptly after receipt of the
Proposed Budget and the Three-Year Strategic Plan, but in any event not less
than thirty (30) days prior to the end of the calendar year, the Vitrocrisa
Board shall meet to review the Proposed Budget and the Three-Year Strategic
Plan. Upon such review, the Vitrocrisa Board will vote on the Proposed Budget
and the Three-Year Strategic Plan. If the Proposed Budget is approved by
Extraordinary Directors Action, the Proposed Budget shall become Vitrocrisa's
operating budget for the next succeeding calendar year. If the Proposed Budget
is not approved by Extraordinary Directors Action, the Managing Director will
revise the Proposed Budget as soon as possible and resubmit it to the Vitrocrisa
Board for consideration by Extraordinary Directors Action. The operating budget
for the previous calendar year shall continue to govern the operations of
Vitrocrisa (but (a) revised to the extent the parties agree and (b) in any
event, adjusted for inflation provided that such adjustment does not affect
Libbey's Expected Sales target (as defined in the Distribution Agreement, dated
of even date, by and among Vitro, Crisa Corporation, Vitrocrisa, Libbey, and
Libbey Glass Inc.)) until such time as a Proposed Budget is approved by the

         8.10.    Dispute Resolution.
                  -------------------

         (a) The parties to this Agreement shall exert good faith efforts to
promptly resolve any controversy or claim arising out of or related to this
Agreement or the breach thereof within fifteen (15) days of receipt of notice by
one party from another party that such a controversy or claim exists. If the
parties fail to resolve such controversy or claim within such fifteen (15) day
period, they shall, unless otherwise provided in this Agreement, give notice in
writing to the CEOs, who will meet within fifteen (15) days of receipt of such
notice at a mutually acceptable time and place to attempt to resolve any such
controversy or claim. In the event the CEOs fail to meet or to resolve the
controversy or claim within such fifteen (15) day period, the controversy or
claim (other than business and operational decisions customarily exercised by
management in entities similar to Vitrocrisa) shall be settled by arbitration in
accordance with the then existing International Arbitration Rules of the
American Arbitration Association (hereinafter "AAA"), which shall commence upon
one party providing the other parties with a written demand for arbitration (the
"DEMAND FOR ARBITRATION").

         (b) The arbitral tribunal shall be composed of three arbitrators, and
Libbey and Vitro shall each appoint one arbitrator. If Libbey or Vitro fail to
appoint an arbitrator within thirty (30) days after the date the claimant's
Demand for Arbitration is communicated to the other parties 


                                      -22-
<PAGE>   23



(hereinafter the "NOTIFICATION DATE"), the AAA shall make such appointment. The
two arbitrators thus appointed shall attempt to agree upon the appointment of a
third arbitrator to serve as chairman of the arbitral tribunal. If said two
arbitrators fail to agree upon the appointment of such third arbitrator within
sixty (60) days after the Notification Date, the AAA shall make such
appointment. The place of arbitration shall be Dallas, Texas, United States of
America. The arbitral proceeding shall be conducted in the English language.

         (c) To the extent that they may validly so agree, the parties hereby
exclude any right of appeal to any court in connection with the arbitral award.
Judgment upon the arbitral award may be entered in any court having jurisdiction
thereof or having jurisdiction over any party or any party's assets.

         (d) The validity of this SECTION 8.10 shall be governed by the United
Nations Convention on the Recognition and Enforcement of Foreign Arbitral Awards
or the Inter-American Convention on International Commercial Arbitration, to
which Mexico and the United States of America have adhered.

         (e) All costs of arbitration and enforcement thereof, including
reasonable attorneys' fees and court costs, costs of expert witnesses,
transportation, lodging, and meal costs of the parties and witnesses, costs of
transcript preparation, and other reasonable and necessary direct and incidental
costs shall be apportioned to one or more of the parties by a majority of the
arbitrators as they deem appropriate. In the event any party to this Agreement
commences legal proceedings to enforce the arbitral award, the expense of such
litigation (including reasonable attorneys' fees and costs of court) shall be
borne by the party or parties not prevailing therein.

         (f) This SECTION 8.10 will not apply to any matter that is to be
resolved pursuant to ARTICLE V or pursuant to ARTICLE VI.

         8.11     CONFIDENTIALITY.
                  ----------------

                  8.11.1. Each Shareholder shall use best efforts to maintain in

affiliated with a Shareholder without the prior written consent of the other
Shareholder, provided that each Shareholder shall be entitled to use the
Confidential Information for any and all lawful purposes relating to its
business, operations and activities, including the financing and auditing
thereof. For purposes of this Agreement "Confidential Information" shall mean
all confidential or proprietary information of Vitrocrisa relating to its
business or operations or of a Shareholder which is provided for or in
connection with the business or operations of Vitrocrisa, which is provided to a
Shareholder or any of their respective Representatives (as defined below) by
Vitrocrisa or by any other Shareholder or any of its Representatives and

provided, however, that the term shall not include (i) information known to the
recipient prior to receipt thereof from the other Shareholder or from Vitrocrisa
in connection with this Agreement, (ii) information which, at the time of
disclosure hereunder, is already in the public domain, (iii) information which,
after disclosure hereunder, becomes part of the public domain by publication or
otherwise through no fault of the recipient, (iv) information obtained by a
recipient from a 


                                      -23-
<PAGE>   24



third party (not Affiliated with a Shareholder) in lawful possession of such
information which is not under a confidentiality obligation to the Person (as
defined below) from whom such information originated or (v) information that is
independently developed without the benefit of the Confidential Information.

                  8.11.2. Notwithstanding the provisions of Section 8.11.1, each
Shareholder may disclose Confidential Information to its or its Affiliates'
respective Representatives, provided that (a) such Representative has a need to
receive such Confidential Information to perform its duties, (b) the disclosing
Shareholder advises such Representative of the confidential nature of the
disclosed Confidential Information, and (c) the disclosing Shareholder uses all
reasonable efforts to cause such Representative to protect and maintain the
confidentiality of the disclosed Confidential Information as provided herein.

                  8.11.3. Notwithstanding the provisions of Section 8.11.1, each
Shareholder may disclose Confidential Information (i) in connection with reports
of earnings of a Shareholder, (ii) to the extent, in the opinion of such
Shareholder's legal counsel, required by the laws applicable to such
Shareholder, including without limitation, all securities laws, or (iii) in
cases involving dispute resolution under the procedures set forth in 8.10.

                  8.11.4 For purposes of this Section 8.11, the following terms
shall have the meanings given them below:

"Representatives" shall mean, with respect to any Person, such Person's owners,
stockholders, partners, directors, officers, employees, agents, consultants,
advisors (including, without limitation, auditors, engineers, financial
analysts, financial managers and attorneys), and lenders;

"Person" shall mean any natural person, any corporation, partnership, limited
liability company, trust or other entity, and any governmental or judicial

Person that directly, or indirectly through one or more intermediaries, controls
such Person, (ii) any other Person that is controlled by or is under common
control with such Person, or (iii) any subsidiary of such Person.

                  8.11.5. The obligations of the Shareholders under this Section
8.11 shall survive the expiration or termination of this Agreement to the
maximum extent permitted by applicable law.

                  8.11.6. To be Confidential Information, all information
disclosed in tangible form shall be conspicuously marked confidential or
proprietary at the time of initial disclosure to the recipient and information
conveyed orally shall be identified as confidential or proprietary at the time
of initial disclosure to the recipient and summarized in writing, conspicuously
marked confidential or proprietary and given to the recipient within thirty days
after the initial disclosure. Information not so identified will not be deemed
to be Confidential Information.

<PAGE>   25



                  8.11.7 In the event any Shareholder is requested or required
(by deposition, interrogatories, requests for information or documents in legal
proceedings, subpoena, civil investigative demand or similar process), in
connection with any proceeding, to disclose any Confidential Information, the
Shareholder that is requested or required will give Vitrocrisa and the other
Shareholder written notice of such request or requirement so that the
Shareholder receiving the notice or Vitrocrisa may seek an appropriate
protective order or other remedy. In the event such protective order or other
remedy is not obtained in a timely manner, the Shareholder to whom such request
or requirement is directed will furnish only that portion of the Confidential
Information that, in the opinion of counsel to such Shareholder, is legally
required to be disclosed and, upon the request of the other Shareholder or
Vitrocrisa, use its best efforts to obtain assurances that confidential
treatment will be accorded to such information.

         8.12. AMENDMENTS AND WAIVERS. This Agreement may be amended, modified,
superseded, or canceled and any of its terms, covenants, representations,
warranties, undertakings, or conditions may be waived only by an instrument in
writing signed by (or by some person duly authorized by) all of the parties
hereto or, in the case of a waiver, by the party waiving compliance.

         8.13. SEVERABILITY. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration, or area of the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed.

         8.14. EXHIBITS AND SCHEDULES. The Exhibits and Schedules identified in
this Agreement are incorporated herein by reference and made a part hereof.

         8.15. PRESS RELEASES AND ANNOUNCEMENTS. No party shall issue any press
release or announcement relating to the subject matter of this Agreement without
the prior written approval of the other parties hereto; provided, however, that
any party may make any public disclosure it believes in good faith is required
by law or regulation (in which case the disclosing party will advise the other
party prior to making the disclosure).

         8.16. NO VIOLATION OF LAW. This Agreement shall not be construed to
require either party to be compelled, and no party will compel Vitrocrisa, to do
any act or remain in any situation in violation of any law of a governmental
authority applicable to such party.

         8.17. VITRO UNDERTAKING. Vitro agrees to do such things and take such
actions so as to enable VC Holding and Vitrocrisa to fulfill its obligations
under this Agreement.

                        VITROCRISA HOLDING, S.A. DE C.V.
                             SHAREHOLDERS AGREEMENT


         THIS AGREEMENT is made and entered effective as of August 29, 1997, by
and among LIBBEY INC., a corporation organized under the laws of the State of
Delaware ("LIBBEY"), LGA3 CORP., a corporation organized under the laws of the
State of Delaware and a wholly-owned subsidiary of Libbey ("LGA3"), VITRO, S.A.,
a sociedad anonima organized under the laws of the United Mexican States
("VITRO"), and VITROCRISA HOLDING, S.A. DE C.V., a sociedad anonima with
variable capital organized under the laws of the United Mexican States ("VC
HOLDING"). LGA3 and Vitro are sometimes singularly referred to herein as a
"SHAREHOLDER" and collectively referred to herein as the "SHAREHOLDERS."

                                  Introduction
                                  ------------

         Libbey and Vitro desire to establish a joint business venture to
manufacture in Mexico and to market, distribute, and sell glass tableware and
related industrial products in North America, Central America, and South
America. To achieve these goals, Libbey (and certain of its subsidiaries) and
Vitro (and certain of its subsidiaries) entered into that certain Master
Investment Agreement dated of even date (the "MASTER INVESTMENT AGREEMENT").
Pursuant to the Master Investment Agreement, LGA3 acquired all of the Series B
Shares of VC Holding, which represents forty-nine percent (49%) of the total
issued and outstanding capital stock of VC Holding. Vitro owns all of the Series
A Shares of VC Holding, which represents fifty-one percent (51%) of the total
issued and outstanding capital stock of VC Holding.


         Libbey, LGA3, Vitro, and VC Holding each desire to enter into this
Agreement for the purpose of setting forth the principles for the adoption of
decisions in Vitrocrisa, S.A. de C.V., a sociedad anonima with variable capital
organized under the laws of the United Mexican States and wholly-owned by VC
Holding, Vitro, and LGA3 ("VITROCRISA"). Therefore, in consideration of the
mutual promises contained herein, together with other consideration, the
adequacy and receipt of which are hereby acknowledged, the parties hereto agree
as follows:

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

         3.1. THE SHAREHOLDERS MEETINGS; QUORUM. The shareholders meeting is the
supreme authority of VC Holding. The shareholders meetings may be ordinary (an
"ORDINARY SHAREHOLDERS MEETING") or extraordinary (an "EXTRAORDINARY
SHAREHOLDERS MEETING"), depending on the matters to be discussed at each
meeting. They will be held at the corporate domicile of VC Holding in accordance
with the call for the meeting made pursuant to the Revised VC Holding Estatutos.
According to the General Law of Mercantile Companies of Mexico, resolutions may
be adopted outside of a shareholders meeting by unanimous vote of the
Shareholders, provided that the Shareholders subsequently confirm the adoption
of such resolutions in writing to the Chairman or the Secretary of the VC
Holding Board. An Ordinary Shareholders Meeting will be held at least once a
year within the four (4) months following the closing of each fiscal period.
Ordinary Shareholders Meetings may be those called to discuss any of the matters
that are not expressly reserved by law or this Agreement to the Extraordinary
Shareholders Meeting. The matters reserved for Extraordinary Shareholders
Meetings are:

         (a)      any matter that is required to be resolved by the
                  Extraordinary Shareholders Meeting according to Article 182 of
                  the General Law of Mercantile Companies;

         (b)      the declaration or payment of dividends pursuant to the
                  Dividend Policy; and

         (c)      any matter specified in SECTION 3.2(d) that is referred to the
                  Shareholders by the VC Holding Board.

         An Ordinary Shareholders Meeting shall take place by virtue of a first
call of any Shareholder if the holders of fifty-five percent (55%) of the
capital stock are present or duly represented thereat. If such a quorum does not
exist for the holding of the meeting by virtue of the first call, the call shall
be repeated, and the meeting shall be considered validly held whatever number of
Shareholders are present or represented. Resolutions in Ordinary Shareholders
Meetings shall be adopted by the affirmative vote of the majority of the shares
entitled to vote that are present or represented thereat.

         An Extraordinary Shareholders Meeting shall be held by virtue of the
first call if the Shareholders holding at least seventy-five percent (75%) of
the capital stock are present or represented thereat. If such a quorum does not
exist for such meeting, the call shall be repeated, and the meeting shall be
considered validly held only with the attendance of Shareholders or their



                                      -3-
<PAGE>   4


proxies representing at least fifty-five percent (55%) of the capital stock of
VC Holding. Resolutions in Extraordinary Shareholders Meetings held either in
first or subsequent calls shall be adopted by the affirmative vote of
Shareholders or their representatives holding at least fifty-five percent (55%)
of the capital stock of VC Holding.

         If holders of seventy-five percent (75%) of the capital stock are not
present or represented at the first call of any Extraordinary Shareholders
Meeting and if holders of fifty-five percent (55%) of the capital stock are not
present or represented at any repeated call of such meeting, either Shareholder
shall have the right, but shall not be obligated, to declare the occurrence of a
Deadlock Event under SECTION 6.1.

         In addition to any other requirement imposed by Mexican law, calls for
an Ordinary Shareholders Meeting of VC Holding and calls for an Extraordinary
Shareholders Meeting of VC Holding must be in writing and must be delivered to
each Shareholder at least fifteen (15) days prior to such meeting, unless such
notice is waived by the Shareholders in writing.

entitled, in its sole and absolute discretion, to designate four (4) Members
(and their alternates) to the VC Holding Board (hereinafter referred to
singularly as a "VITRO MEMBER" and collectively as "VITRO MEMBERS"), provided
that each such designee is also a member or alternate, as the case may be, of
the Board of Directors of Vitrocrisa. As the owner of Series B Shares of VC
Holding, LGA3 shall be entitled, in its sole and absolute discretion, to
designate three (3) Members (and their alternates) to the VC Holding Board

         (b) REMOVAL. Each Shareholder, in its sole and absolute discretion, may

and alternates it has designated. Notwithstanding the foregoing, each
Shareholder hereby agrees to consult with the other Shareholder in connection
with the designation, removal, and replacement of any Member and alternate of
the VC Holding Board and to consider reasonable objections of any Shareholder to
the designation, removal, and replacement of any Member and alternate of the VC
Holding Board; provided, however, such consultation shall not affect the sole
and absolute discretion of each Shareholder to designate, remove, or replace the
Members and alternates it has designated. Any alternate may substitute for any
Member designated by such Shareholder at any meeting of the VC Holding Board. No
Member or alternate of the VC Holding Board shall be removed or replaced other
than by the Shareholder that designated such Member or alternate.

                           law, including powers under Article 2554 of the Civil
                           Code for the Federal District and Articles 9 and 85
                           of the General Law of Negotiable Instruments and

         (d) EXTRAORDINARY DIRECTORS ACTIONS. Notwithstanding anything contained

                           financial statements and report for approval.

         (e) MEETINGS. The VC Holding Board shall meet at least twice annually,
the first meeting being within thirty (30) days after year-end audited financial
statements have been delivered to all Members of the VC Holding Board, but in no
event more than four (4) months after the end of each fiscal year, or more
frequently at the request of any Shareholder or any Member. Notice of each
meeting of the VC Holding Board must be delivered to all Members at least
fifteen (15) days in advance of the date of such meeting. At least four (4)
Members of the VC Holding Board or their alternates must be present to transact
business. Each meeting of the VC Holding Board shall take place at 10:00 a.m. on
the fifteenth (15th) day after notice has been delivered to all Members, or at a
time and place mutually agreed upon by the Members. If Members sufficient to
transact business are not present at the meeting, the date of the meeting shall
be postponed for one (1) day, and if Members sufficient to transact business are
not present at that meeting, the date of the meeting shall be postponed for an
additional day. If Members sufficient to transact business are not present at
that meeting, either Shareholder shall have the right, but shall not be
obligated, to declare the occurrence of a Deadlock Event under SECTION 6.1
hereof.

         (f) WAIVER OF NOTICE; VOTING. The Members can waive the requirement of
the written call, and same will not be required, when all of the Members or
their alternates are present at the meeting. Except as otherwise provided
herein, all decisions of the VC Holding Board shall require the approval of a
majority of its Members. All decisions of the Members on any matters requiring
their approval, consent, or action may be made by the Members in each of their
sole and absolute discretion.

         (g) ACTION WITHOUT MEETING. Whenever the VC Holding Board is required
or permitted to take any action pursuant to a meeting of the VC Holding Board,
such action may be taken without a meeting upon a written consent, setting forth
the action so taken that is signed by each of the Members.

         3.3. INDEMNIFICATION OF THE VC HOLDING BOARD. Each Member shall be
indemnified by VC Holding against all liability for any claim, demand, loss,
damage, liability, or expense (including, without limitation, amounts paid in
settlement, reasonable costs of investigation, and reasonable legal expenses)
resulting from any threatened, pending, or completed action, suit, or 



                                      -6-

proceeding naming any of them as defendant by reason of acts or omissions made
or omitted in good faith within the scope of their authority as set forth in
this Agreement to the maximum extent permitted by law.

         3.4. MANAGEMENT AND ADMINISTRATIVE SERVICES BY VITRO AND LIBBEY.
Neither Shareholder shall be entitled to a fee for any management or
administrative services provided to VC Holding by such Shareholder unless
mutually agreed by both Shareholders.

         3.5. CORPORATE OPPORTUNITY. No person or entity of the Libbey 100%
Group (as defined in ARTICLE IV) and no person or entity of the Vitro 100% Group
(as defined in ARTICLE IV) has any duty to communicate or offer any Corporate
Opportunity (as defined below) to VC Holding, and neither the Libbey 100% Group
nor the Vitro 100% Group shall be liable to VC Holding or any Shareholder for
breach of any fiduciary duty or duty of loyalty to VC Holding by reason of the
fact that it pursues or acquires a Corporate Opportunity for itself or directs a
Corporate Opportunity to another person or entity. For purposes of this section,
"CORPORATE OPPORTUNITY" means a business or other opportunity that VC Holding is
or could reasonably be expected to become financially able to undertake, which
relates to VC Holding's line of business and in which VC Holding has or would
have an interest or a reasonable expectancy of interest. To the extent this
SECTION 3.5 contradicts any term or provision in the Distribution Agreement,
dated of even date, by and among Vitro, Vitrocrisa, Libbey, and Libbey Glass
Inc., the Distribution Agreement, dated of even date, by and among Vitro, Crisa
Corporation, Vitrocrisa, Libbey, and Libbey Glass Inc. (together, the
"DISTRIBUTION AGREEMENTS"), or the Covenant Not to Compete, dated of even date,
by and between Libbey and Vitro (the "COVENANT NOT TO COMPETE"), the terms and
provisions of the Distribution Agreements or the Covenant Not to Compete shall
control.

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

         (a) TRANSFERS. No Shareholder shall cause VC Holding to transfer all or
any portion of its interest in Vitrocrisa, or agree to do so, without the
written consent of each of Libbey and Vitro. No Shareholder shall transfer all
or any portion of its interest in VC Holding or its rights under this Agreement,
or agree to do so, for a period of four (4) years from the date of this
Agreement. After such four-year period, either Shareholder may transfer all, but
not less than all, of its interest in VC Holding pursuant to the terms of
SECTION 4.2. A Shareholder may transfer or otherwise sell its shares pursuant to
this ARTICLE IV for any reason.

         (b) ENCUMBRANCE. Except as otherwise provided in this Agreement, no
Shareholder may encumber, mortgage, pledge, hypothecate, or place a lien or make
any disposition similar thereto (collectively an "ENCUMBRANCE") upon all or any
portion of its interest in VC Holding or its rights under this Agreement, or
agree to do so, without the prior written consent of the other Shareholder,
which consent shall not be unreasonably withheld but may be subject to such


                                      -7-
<PAGE>   8



reasonable conditions as the other Shareholder may require. Except as otherwise
provided in this Agreement, no Shareholder shall cause VC Holding to place an
Encumbrance upon all or any portion of its interest in Vitrocrisa or its rights
under this Agreement, or agree to do so, without the prior written consent of
Libbey and Vitro, which consent shall not be unreasonably withheld but may be
subject to such reasonable condition as the other Shareholder may require.

         (c) VIOLATION. Any purported transfer or Encumbrance in violation of
the terms of this Agreement shall be null and void and shall not be recognized
by VC Holding.

                                           other person or entity that directly
                                           or indirectly controls, is controlled
                                           by, or is under common control with
                                           Vitro, excluding Vitrocrisa (the
                                           "VITRO 100% GROUP"), and in the case
                                           of LGA3, Libbey or any other person
                                           or entity that directly or indirectly
                                           controls, is controlled by, or is
                                           under common control with Libbey (the
                                           "LIBBEY 100% GROUP").

         (b) LIMITATION ON TRANSFERS. The right to transfer or dispose of shares
of VC Holding or any interest therein shall (save in respect of transfers made
pursuant to SECTION 4.2(i)) be subject to the restrictions set forth in this
SECTION 4.2. A Shareholder may not transfer or dispose of its shares in VC
Holding unless it transfers or disposes of all of its Joint Venture Interest.
Except as provided otherwise herein, no Shareholder may transfer or dispose of
its Joint Venture Interest (save in respect of transfers made pursuant to
SECTION 4.2(i) hereof) without the prior written consent of the other
Shareholder.

         (c) FIRST OPTION. Before transferring or disposing of all of its Joint
Venture Interest (or any interest therein), the Proposing Transferor shall serve
a Transfer Notice on the other Shareholder stipulating the Prescribed Price.
Upon receipt of a Transfer Notice, the other Shareholder shall have the right
and first option for a period of thirty (30) days to purchase all of the Joint
Venture Interest at the Prescribed Price.

         (d) TRANSFER ON EXERCISE OF OPTION. If the Proposing Transferor is
given notice under SECTION 4.2(c) that the other Shareholder has exercised its
option to purchase all, but not less than all, of the Joint Venture Interest,
the Proposing Transferor shall be bound, on payment of the Prescribed Price, to
transfer the Joint Venture Interest to the other Shareholder or its designees.
The sale and purchase shall be completed at the office of VC Holding, or at such
other place as the Proposing Transferor and the other Shareholder shall agree,
during normal business hours on the first business day after the expiration of
ninety (90) days after the expiration of the option period set forth in SECTION
4.2(c).

         (e) TRANSFER ON EXPIRATION OR TERMINATION OF OPTION. If the option
granted by SECTION 4.2(c) is not exercised as to all of the Joint Venture
Interest, then such option shall become void AB INITIO and the Proposing
Transferor may sell all of the Joint Venture Interest to any third party free of
the restrictions set forth in this ARTICLE IV, subject to the following
restrictions: (i) the Joint Venture Interest may not be sold after the
expiration of one hundred eighty (180) days after the expiration of the option
period set forth in SECTION 4.2(c), (ii) the Joint Venture Interest must be sold
in a bona fide sale at a price not being less that the Prescribed Price, and
(iii) the third party transferee of the Joint Venture Interest must execute and
deliver an undertaking under which such third party shall become a party hereto,
to the Vitrocrisa, S.A. de C.V. Shareholders Agreement dated of even date (the
"VITROCRISA SHAREHOLDERS AGREEMENT"), to the Crisa Libbey, S.A. de C.V.
Shareholders Agreement dated of even date (the "NEWCO FINANCE SHAREHOLDERS
AGREEMENT"), and to the Limited Liability Company Agreement of Crisa Industrial,
L.L.C. dated of even date (the 


                                      -9-
<PAGE>   10



"LLC AGREEMENT," and collectively with this Agreement, the Vitrocrisa
Shareholders Agreement, and the Newco Finance Shareholders Agreement, the "JOINT
VENTURE SHAREHOLDERS AGREEMENTS") in place of the Proposing Transferor.

         (f) EXERCISE. An option granted by SECTION 4.2(c) may be exercised only
by the holder thereof and only by the delivery of a written notice of exercise
to the Proposing Transferor prior to the expiration of the relevant option
period.

         (g) WAIVER. The restrictions imposed by this ARTICLE IV may be waived
in relation to any proposed transfer of a Shareholder's Joint Venture Interest
with the consent of all Shareholders who would otherwise have been entitled to
have such Joint Venture Interest offered to them in accordance herewith.

         (h) FAILURE TO TIMELY EXERCISE. Failure of a Shareholder to exercise an
option granted by SECTION 4.2(c) prior to the expiration of the option period
shall be deemed to be a waiver of that option as of the date the option period
expired. The waiver of an option granted by SECTION 4.2(c) will not constitute a
waiver of any subsequent option granted by SECTION 4.2(c).

         (i) INTRA-GROUP TRANSFERS. Notwithstanding the foregoing, all, but not
less than all, of a Shareholder's Joint Venture Interest may be transferred to
any member of the Vitro 100% Group (in the case of Vitro) and to any member of
the Libbey 100% Group (in the case of LGA3), but only (i) if the transferee is
already a party to each of the Joint Venture Shareholders Agreements or shall
have first agreed to adhere to and be bound by the provisions of each of the
Joint Venture Shareholders Agreements by executing and delivering in favor of
the other parties to each of the Joint Venture Shareholders Agreements an
undertaking to the intent and with the effect that from the date of such
undertaking, or, if later, the date of the transfer, the transferee shall become
a party to each of the Joint Venture Shareholders Agreements, in place of the
transferor, to the extent that the transferor ceases to hold shares in VC
Holding, Vitrocrisa, Newco Finance, and the LLC as a result of such transfer;
and (ii) on terms that the transferee shall re-transfer the relative Joint
Venture Interest to a member of the Vitro 100% Group (in the case of Vitro) or
to a member of the Libbey 100% Group (in the case of LGA3) on the same terms as
set forth in SECTION 4.2(i), prior to such transferee ceasing to be a member of
the Vitro 100% Group or the Libbey 100% Group (as the case may be).

         (j) OPTION TO PARTICIPATE IN SALE. In lieu of exercising the option
granted in SECTION 4.2(c), a Shareholder may elect to participate in any sale by
the Proposing Transferor contemplated by SECTION 4.2 at the Prescribed Price.
Upon such election, the Shareholder will be entitled to sell all of its Joint
Venture Interest. The election to participate in a sale must be in writing and
must be delivered to the Proposing Transferor within thirty (30) days of receipt
of the Transfer Notice. Failure to timely deliver a written election to
participate in a sale within thirty (30) days of the Transfer Notice will
constitute a waiver of such Shareholder's right to participate in the sale.

                                    ---------

                                   Termination
                                   -----------

         5.1. CAUSES OF TERMINATION. Except as otherwise provided in this
Agreement, this Agreement shall terminate:

         (a)      upon the unanimous written consent of the parties hereto;

         (b)      if VC Holding is declared bankrupt, has a receiver appointed
                  over all or substantially all of its assets, or is dissolved;

         (c)      by decree of a court of competent jurisdiction; or

         (d)      upon the merger of VC Holding into Vitrocrisa; provided,
                  however, that the parties expressly agree that, upon the
                  occurrence of such merger, the parties shall enter into a new
                  agreement having terms substantially similar to, and with the
                  same intent of, the terms of the Vitrocrisa Shareholders
                  Agreement.

         5.2. EVENTS OF DEFAULT. The occurrence of any of the following events
shall constitute an event of default ("EVENT OF DEFAULT") hereunder on the part
of the Shareholder with respect to whom such event occurs (the "DEFAULTING
PARTY") without any requirement of notice or passage of time except as
specifically set forth in any such subparagraph:

         (a)      the violation by a Shareholder or Libbey of any of the
                  restrictions set forth in ARTICLE IV;

         (b)      failure of a Shareholder's Member of the VC Holding Board to

                  Policy as set forth in SECTION 2.2;

         (c)      the institution by a Shareholder or Libbey of a case or other
                  proceeding in bankruptcy;

         (d)      the institution against a Shareholder or Libbey of a case or
                  other proceeding in bankruptcy, which proceeding is not
                  dismissed, stayed, or discharged within a period of sixty (60)
                  days after the filing thereof;

         (e)      a proposed plan of arrangement or other action by a
                  Shareholder's or Libbey's creditors taken as a result of a
                  general meeting of the creditors of a Shareholder or Libbey,
                  respectively, which arrangement or other action is not
                  dismissed, stayed, or discharged within a period of sixty (60)
                  days after such general meeting;

         (f)      the appointment of a receiver, custodian, trustee, or like
                  officer, to take possession of the assets of a Shareholder or
                  Libbey if the pendency of said receivership would reasonably
                  tend to have a materially adverse effect upon the performance
                  by the 


                                      -11-
<PAGE>   12



                  Shareholder or Libbey, respectively, of its obligations under
                  this Agreement, which receivership remains undischarged for a
                  period of sixty (60) days from the date of its imposition;

         (g)      attachment, execution, or other judicial seizure of all or any
                  substantial part of a Shareholder's or Libbey's assets or of a
                  Shareholder's or Libbey's shares of VC Holding, or any part
                  thereof, such attachment, execution, or seizure remaining
                  undismissed or undischarged for a period of sixty (60) days
                  after the levy thereof, if the occurrence of such attachment,
                  execution, or other judicial seizure would reasonably tend to
                  have a materially adverse effect upon the performance by the
                  Shareholder or Libbey, respectively, of its obligations under
                  this Agreement; provided, however, that said attachment,
                  execution, or seizure shall not constitute an Event of Default
                  hereunder if the Shareholder or Libbey, respectively, posts a
                  bond sufficient to fully satisfy the amount of such claim or
                  judgment within sixty (60) days after the levy thereof and the
                  respective Shareholder's or Libbey's assets are thereby
                  released from the lien of such attachment;

         (h)      material default in performance of or a failure to comply with
                  any obligations or undertakings of a Shareholder or Libbey
                  under the Covenant Not to Compete dated of even date by and
                  between Vitro and Libbey, and such default continues for a
                  period of thirty (30) days following notice of such default by
                  another Shareholder;

         (i)      the occurrence of an Event of Default (as defined therein)
                  under ARTICLE V of the Vitrocrisa Shareholders Agreement; and

         (j)      the occurrence of a Libbey Change of Control or a Vitro Change
                  of Control (both as defined in SECTION 5.6 below).

         5.3. REMEDY ON DEFAULT. If an Event of Default is declared pursuant to
(a) SECTION 5.2(b) with respect to dividends to be paid for the performance of
VC Holding during fiscal years 1998, 1999, and 2000 or (b) SECTION 5.2(j) with
respect to a Libbey Change of Control or a Vitro Change of Control occurring on
or before the third anniversary of this Agreement, then such Shareholder may, in
addition to any other remedy at law or in equity, invoke the provisions of
SECTION 5.5. If an Event of Default is declared at any time (a) by a Shareholder
pursuant to any other subsection of SECTION 5.2, (b) by any party to this
Agreement pursuant to SECTION 5.2(b) with respect to dividends to be paid for
the performance of VC Holding after fiscal year 2000, or (c) by a Shareholder
pursuant to SECTION 5.2(j) with respect to a Libbey Change of Control or a Vitro
Change of Control occurring after the third anniversary of this Agreement, then
such Shareholder may, in addition to any other remedy at law or in equity,
invoke the provisions of SECTION 5.4.

         5.4. BUY/SELL PROVISION. Within forty-five (45) days of an Event of
Default the non-defaulting party (the "OFFERING SHAREHOLDER") may deliver a
written offer (the "OFFER") to purchase all, but not less than all, of the other
Shareholder's Joint Venture Interest at a cash purchase price (the "OFFER
PRICE"), fully payable on or before sixty (60) days after notice of the Offer.
Within thirty (30) days after receipt of the Offer, the other Shareholder may
notify the Offering 



                                      -12-
<PAGE>   13



Shareholder in writing that it will either (i) sell to the Offering Shareholder
all, but not less than all, of its Joint Venture Interest at the Offer Price on
or before the sixtieth day after receipt of the Offer or (ii) buy from the
Offering Shareholder all, but not less than all, of the Offering Shareholder's
Joint Venture Interest at (A) if Vitro is the Offering Shareholder, 51/49 of the
Offer Price or (B) if LGA3 is the Offering Shareholder, 49/51 of the Offer Price
(the "ADJUSTED OFFER PRICE"), on or before the sixtieth day after receipt of the
Offer. If the other Shareholder fails to notify the Offering Shareholder within
the thirty (30) day period that it will (i) sell all of its Joint Venture
Interest to the Offering Shareholder at the Offer Price or (ii) buy all of the
Joint Venture Interest from the Offering Shareholder at the Adjusted Offer
Price, then the Offering Shareholder must purchase in cash all, but not less
than all, of the other Shareholder's Joint Venture Interest at the Offer Price
and the other Shareholder must sell all, but not less than all, of its Joint
Venture Interest at the Offer Price, on or before the sixtieth day after notice
of the Offer. Upon the purchase or sale of shares pursuant to this SECTION 5.4,
this Agreement shall automatically terminate without further action by either
Shareholder. Failure by the non-defaulting party to deliver an Offer within
forty-five (45) days of notice of an Event of Default shall constitute a waiver
of such party's rights under this SECTION 5.4 with respect to the particular
Event of Default.

         5.5.     Dispute Resolution; Put/Call Option.
                  ------------------------------------

         (a) DISPUTE RESOLUTION. If an Event of Default is declared by a
Shareholder pursuant to (i) SECTION 5.2(b) with respect to dividends to be paid
for the performance of VC Holding during fiscal years 1998, 1999 and 2000 or
(ii) SECTION 5.2(j) with respect to a Libbey Change of Control or a Vitro Change
of Control occurring on or before the third anniversary of this Agreement, such
Shareholder shall promptly (but in no event later than thirty (30) days after
such Shareholder's knowledge of such Event of Default) send notice of such Event
of Default to the other Shareholder (the "DEFAULT NOTICE"). Upon receipt of the
Default Notice, the alleged defaulting party will have thirty (30) days to cure
such default. If the default is not cured within such thirty (30) day period or
if the party receiving the Default Notice contests that a default has occurred,
the chief executive officers of Libbey and Vitro (collectively, the "CEOS")
shall meet within ninety (90) days of the expiration of the cure period in a
good faith effort to resolve the Event of Default. If the Event of Default is
not resolved within such ninety (90) day period, the CEOs may select an
independent mediator and subject the dispute to non-binding mediation, which
must take place within thirty (30) days of the expiration of such ninety (90)
day period. If both CEOs do not consent to non-binding mediation or if the
mediation fails to resolve the Event of Default, the Event of Default shall be
submitted to binding arbitration to be conducted in accordance with the
provisions of SECTION 8.10(b), (c), (d), and (e), the sole purpose of which is
to decide whether a default exists and, if so, which Shareholder is in default.
The arbitrators will consider all issues currently in dispute between the
Shareholders and must certify their ruling in writing to each Shareholder (the
date of such certification is referred to herein as the "CERTIFICATION DATE").
If the arbitrators determine and certify that one Shareholder is in default,
then such Shareholder shall have thirty (30) days from the Certification Date to
cure the default. If the Event of Default is not cured within such thirty (30)
day period, the non-defaulting party may invoke the provisions of SECTION
5.5(b). If the arbitrators cannot resolve which party has caused the Event of
Default or determine that both Shareholders have caused the Event of Default and
so certify, then either of the Shareholders may invoke the provisions of SECTION
5.4 within thirty (30) days of the Certification Date.



                                      -13-

         (B)      Put/Call Option with Penalty.
                  -----------------------------

                  (i) PUT/CALL OPTION WITH PENALTY. If the arbitrators determine
         that Vitro or any member of the Vitro 100% Group is in default and such
         default shall not be cured within thirty (30) days of the Certification
         Date, then Libbey shall have the right to sell to Vitro, and Vitro
         shall be obligated to purchase from Libbey, all, but not less than all,
         of Libbey's Joint Venture Interest at forty-nine percent (49%) of the
         Joint Venture Value (as defined below) multiplied by one hundred twenty
         percent (120%) (the "PUT OPTION"). If the arbitrators determine that
         Libbey or any member of the Libbey 100% Group is in default, then Vitro
         shall have the right to buy from Libbey, and Libbey shall be obligated
         to sell to Vitro, all, but not less than all, of Libbey's Joint Venture
         Interest at forty-nine percent (49%) of the Joint Venture Value (as
         defined below) multiplied by eighty percent (80%) (the "CALL OPTION").
         The Put Option and the Call Option are collectively referred to herein
         as the "OPTION."

                  (ii) VALUATION OF THE JOINT VENTURE. If the party in default
         does not cure the Event of Default within thirty (30) days of the
         Certification Date, the non-defaulting party may request a valuation of
         the joint venture as a going concern, which will include a valuation of
         the combined businesses of Vitrocrisa, VC Holding, Newco Finance, and
         the LLC (collectively, the "JOINT VENTURE"), within thirty (30) days of
         the expiration of the cure period. Within thirty (30) days of the date
         of such request, the CEOs will meet, and each CEO will select one
         investment banker, and the two selected investment bankers will then
         select a third investment banker, for the purpose of establishing a
         value for the Joint Venture as a going concern. Upon selection, each of
         the three investment bankers will independently determine the value for
         the Joint Venture as a going concern, the average of which will be
         deemed to be the joint venture value (the "JOINT VENTURE VALUE").

                  (iii) EXERCISING OPTION. The non-defaulting party may exercise
         the Option by giving the defaulting party written notice of its intent
         to exercise the Option within thirty (30) days of the date that the
         Joint Venture Value is determined by the investment bankers.

                  (iv) CLOSING OF OPTION. The closing of the Option will take
         place at a time and place mutually agreed upon by Libbey and Vitro;
         provided, however, that in no event will the closing take place more
         than sixty (60) days from the date of the notice of exercise set forth
         in SECTION 5.5(b)(iii).

                  (v) INVESTMENT BANKER FEES. Fees and expenses incurred in
         connection with the determination of the Joint Venture Value,
         including, without limitation, investment banker fees, will be paid by
         the party in default as certified by the arbitrators; provided,
         however, that all such fees and expenses will be paid by the
         non-defaulting party if the non-defaulting party fails to exercise the
         Option.

         5.6. DEFINITION OF CHANGE OF CONTROL. In this ARTICLE V, the following
words shall bear the following meanings:


                                      -14-

         (a) "LIBBEY CHANGE OF CONTROL" shall be deemed to have occurred when
(i) any person or entity, together with any group of controlled companies not in
the Libbey 100% Group, acquires beneficial ownership, directly or indirectly, of
shares of stock of Libbey entitling such person or entity to exercise more than
50% of the total voting power of all classes of stock of Libbey entitled to vote
in elections of directors, or (ii) Libbey sells, leases or otherwise transfers
all or substantially all of its assets to any person or entity not in the Libbey
100% Group.

         (b) "VITRO CHANGE OF CONTROL" shall be deemed to have occurred when (i)
any person or entity, together with any group of controlled companies not in the
Vitro 100% Group, acquires beneficial ownership, directly or indirectly, of
shares of stock of Vitro entitling such person or entity to exercise more than
50% of the total voting power of all classes of stock of Vitro entitled to vote
in elections of directors, or (ii) Vitro sells, leases or otherwise transfers
all or substantially all of its assets to any person or entity not in the Vitro
100% Group.


                                   ARTICLE VI
                                   ----------

                              Deadlock and Impasse
                              --------------------

         6.1. DEADLOCK. A "DEADLOCK EVENT" shall be deemed to occur at such time
as a Shareholder (the "NOTIFYING SHAREHOLDER") delivers to the other Shareholder
a notification in writing (the "DEADLOCK NOTICE") stating that, in the opinion
of the Notifying Shareholder, (a) the other Shareholder's chief executive
officer ("CEO") failed to meet with the Notifying Shareholder's CEO to resolve a
controversy or claim regarding a business and operational decision customarily
exercised by the management of VC Holding within the time limits set forth in
SECTION 8.10(a), (b) the other Shareholder has, or the other Shareholder's
Members of the VC Holding Board have, deliberately prevented the occurrence of a
quorum as set forth in SECTION 3.1 or SECTION 3.2(e), respectively, or (c) the
Shareholders or the VC Holding Board are unable to reach agreement on any of the
actions set forth in SECTION 3.1(a), (b), or (c) or SECTION 3.2(d),
respectively, and setting out the reasons therefor, and there is no resolution
or agreement that has been approved by both Shareholders (which approval may be
given or withheld, or made subject to such conditions, as are determined by the
Shareholders in their respective sole and absolute discretion) within seven (7)
days after delivery of the Deadlock Notice. A Deadlock Event shall be resolved
in accordance with the provisions of this ARTICLE VI.

         6.2. RESOLUTION OF DEADLOCK. In the event of a Deadlock Event, either
Shareholder may deliver notice of a meeting of the Shareholders (an "EMERGENCY
NOTICE") to the other Shareholder, and they shall immediately meet at a time and
place mutually agreed upon or, if no time and place is agreeable, at VC
Holding's principal place of business at 10:00 a.m. on the fifteenth (15th) day
after the date of such Emergency Notice. Notwithstanding anything in this
Agreement to the contrary, if either Shareholder does not attend such meeting,
either Shareholder may immediately invoke the provisions of SECTION 6.4.

         6.3. DECLARATION OF IMPASSE. If, at the meeting contemplated in SECTION
6.2, the Shareholders are unable to agree on a course of action to address the
reason for the meeting, any Shareholder may declare an impasse ("IMPASSE") by
giving written notice to the other Shareholder (an "IMPASSE NOTICE"). Within
twenty (20) days after receipt of such Impasse Notice, the CEO of each
Shareholder shall meet in a good faith effort to reach accords that will end the
Impasse. If a decision is not made by common accord that ends the Impasse within
thirty (30) days after the date that the CEOs meet, either Shareholder may
declare a final Impasse ("FINAL IMPASSE") by written notice to the other
Shareholder. Notwithstanding anything in this Agreement to the contrary, if
either CEO refuses to meet with the other CEO, either Shareholder may
immediately invoke the provisions of SECTION 6.4.

         6.4. FINAL IMPASSE. Within forty-five (45) days of notice of Final
Impasse (or pursuant to the provisions of SECTIONS 6.2 or 6.3), either
Shareholder (the "OFFERING SHAREHOLDER") may deliver a written Offer to purchase
all, but not less than all, of the Joint Venture Interest held by the other
Shareholder at a cash Offer Price, fully payable on or before sixty (60) days
after notice of the Offer. Within thirty (30) days after receipt of the Offer,
the other Shareholder may notify the Offering Shareholder in writing that it
will either (a) sell to the Offering Shareholder all, but not less than all, of
its Joint Venture Interest at the Offer Price on or before the sixtieth day
after receipt of the Offer or (b) buy from the Offering Shareholder all, but not
less than all, of the Offering Shareholder's Joint Venture Interest at the
Adjusted Offer Price on or before the sixtieth day after receipt of the Offer.
If the other Shareholder fails to notify the Offering Shareholder within the
thirty (30) day period that it will (a) sell all of its Joint Venture Interest
to the Offering Shareholder at the Offer Price per share or (b) buy all of the
Joint Venture Interest from the Offering Shareholder at the Adjusted Offer
Price, then the Offering Shareholder must purchase in cash all, but not less
than all, of the other Shareholder's Joint Venture Interest at the Offer Price
and the other Shareholder must sell all, but not less than all, of its Joint
Venture Interest at the Offer Price, on or before the sixtieth day after notice
of the Offer. Upon the purchase or sale of shares pursuant to this SECTION 6.4,
this Agreement shall automatically terminate without further action. Failure by
either Shareholder to deliver an Offer within forty-five (45) days of notice of
a Final Impasse shall constitute a waiver of each Shareholder's rights under
this SECTION 6.4 with respect to the particular Final Impasse.

                                   -----------

                     Annual Operating Budgets for VC Holding
                     ---------------------------------------


         7.1. INITIAL STRATEGIC PLAN. The Shareholders agree that the Initial
Strategic Plan for VC Holding will be as set forth on EXHIBIT D to this
Agreement. This plan shall govern the operations of VC Holding for the first
fiscal year following the execution of this Agreement and until otherwise
modified in accordance with this ARTICLE VII.

         7.2. SUBMISSION OF ANNUAL OPERATING BUDGET. At least forty-five (45)
days prior to the end of the calendar year following the expiration of the
Initial Strategic Plan and at least forty-


                                      -16-
<PAGE>   17



five (45) days prior to the end of each subsequent calendar year, the Managing
Director of VC Holding shall prepare a report on VC Holding's working capital
requirements and operating budget for the next succeeding calendar year, which
will contain an itemized estimate of the sources of revenue, the cost of goods
sold, selling, general, and administrative expenses, interest expense, net
income, and all expenditures proposed to be undertaken by VC Holding for such
year (the "PROPOSED BUDGET"). Upon preparation of the Proposed Budget, the
Managing Director shall promptly submit the Proposed Budget to the VC Holding
Board for consideration.

         7.3. APPROVAL OF ANNUAL OPERATING BUDGET. Promptly after receipt of the
Proposed Budget, but in any event not less than thirty (30) days prior to the
end of the calendar year, the VC Holding Board shall meet to review the Proposed
Budget. Upon such review, the VC Holding Board will vote on the Proposed Budget.
If the Proposed Budget is approved by Extraordinary Directors Action, the
Proposed Budget shall become VC Holding's operating budget for the next
succeeding calendar year. If the Proposed Budget is not approved by
Extraordinary Directors Action, the Managing Director will revise the Proposed
Budget as soon as possible and resubmit it to the VC Holding Board for
consideration by Extraordinary Directors Action. The operating budget for the
previous calendar year shall continue to govern the operations of VC Holding
(but (a) revised to the extent the Shareholders agree and (b) in any event,
adjusted for inflation provided that such adjustment does not affect Libbey's
Expected Sales target (as defined in the Distribution Agreement, dated of even
date, by and among Vitro, Crisa Corporation, Vitrocrisa, Libbey and Libbey Glass
Inc.)) until such time as a Proposed Budget is approved by the VC Holding Board
by Extraordinary Directors Action.

         8.10.    Dispute Resolution.
                  ------------------

                  (a) The parties to this Agreement shall exert good faith
efforts to promptly resolve any controversy or claim arising out of or related
to this Agreement or the breach thereof within fifteen (15) days of receipt of
notice by one party from another party that such a controversy or claim exists.
If the parties fail to resolve such controversy or claim within such fifteen
(15) day period, they shall, unless otherwise provided in this Agreement, give
notice in writing to the CEOs, who will meet within fifteen (15) days of receipt
of such notice at a mutually acceptable time and place to attempt to resolve any
such controversy or claim. In the event the CEOs fail to meet or to resolve the
controversy or claim within such fifteen (15) day period, the controversy or
claim (other than business and operational decisions customarily exercised by
management in entities similar to Vitrocrisa) shall be settled by arbitration in
accordance with the then existing International Arbitration Rules of the
American Arbitration Association (hereinafter "AAA"), which shall commence upon
one party providing the other parties with a written demand for arbitration (the
"DEMAND FOR ARBITRATION").

                  (b) The arbitral tribunal shall be composed of three
arbitrators, and Libbey and Vitro shall each appoint one arbitrator. If Libbey
or Vitro fail to appoint an arbitrator within thirty (30) days after the date
the claimant's Demand for Arbitration is communicated to the other parties
(hereinafter the "NOTIFICATION DATE"), the AAA shall make such appointment. The
two arbitrators thus appointed shall attempt to agree upon the appointment of a
third arbitrator to serve as chairman of the arbitral tribunal. If said two
arbitrators fail to agree upon the appointment of such third arbitrator within
sixty (60) days after the Notification Date, the AAA shall make such
appointment. The place of arbitration shall be Dallas, Texas, United States of
America. The arbitral proceeding shall be conducted in the English language.

                  (c) To the extent that they may validly so agree, the parties
hereby exclude any right of appeal to any court in connection with the arbitral
award. Judgment upon the arbitral award 


                                      -19-
<PAGE>   20



may be entered in any court having jurisdiction thereof or having jurisdiction
over any party or any party's assets.

                  (d) The validity of this SECTION 8.10 shall be governed by the
United Nations Convention on the Recognition and Enforcement of Foreign Arbitral
Awards or the Inter-American Convention on International Commercial Arbitration,
to which Mexico and the United States of America have adhered.

                  (e) All costs of arbitration and enforcement thereof,
including reasonable attorneys' fees and court costs, costs of expert witnesses,
transportation, lodging, and meal costs of the parties and witnesses, costs of
transcript preparation, and other reasonable and necessary direct and incidental
costs shall be apportioned to one or more of the parties by a majority of the
arbitrators as they deem appropriate. In the event any party to this Agreement
commences legal proceedings to enforce the arbitral award, the expense of such
litigation (including reasonable attorneys' fees and costs of court) shall be
borne by the party or parties not prevailing therein.

                  (f) This SECTION 8.10 will not apply to any matter that is to
be resolved pursuant to ARTICLE V or pursuant to ARTICLE VI.

         8.11.    Confidentiality.
                  ----------------

                  8.11.1. Each Shareholder shall use best efforts to maintain in
confidence and protect the confidentiality of all Confidential Information and
shall not disclose any Confidential Information to any third party not
affiliated with a Shareholder without the prior written consent of the other
Shareholder, provided that each Shareholder shall be entitled to use the
Confidential Information for any and all lawful purposes relating to its
business, operations and activities, including the financing and auditing
thereof. For purposes of this Agreement "Confidential Information" shall mean
all confidential or proprietary information of VC Holding relating to its
business or operations or of a Shareholder which is provided for or in
connection with the business or operations of VC Holding, which is provided to a
Shareholder or any of their respective Representatives (as defined below) by VC
Holding or by any other Shareholder or any of its Representatives and identified
as confidential or proprietary as required by Section 8.11.6; provided, however,
that the term shall not include (i) information known to the recipient prior to
receipt thereof from the other Shareholder or from VC Holding in connection with
this Agreement, (ii) information which, at the time of disclosure hereunder, is
already in the public domain, (iii) information which, after disclosure
hereunder, becomes part of the public domain by publication or otherwise through
no fault of the recipient, (iv) information obtained by a recipient from a third
party (not Affiliated with a Shareholder) in lawful possession of such
information which is not under a confidentiality obligation to the Person (as
defined below) from whom such information originated or (v) information that is
independently developed without the benefit of the Confidential Information.

                  8.11.2. Notwithstanding the provisions of Section 8.11.1, each
Shareholder may disclose Confidential Information to its or its Affiliates'
respective Representatives, provided that (a) such Representative has a need to
receive such Confidential Information to perform its 


                                      -20-
<PAGE>   21



duties, (b) the disclosing Shareholder advises such Representative of the
confidential nature of the disclosed Confidential Information, and (c) the
disclosing Shareholder uses all reasonable efforts to cause such Representative
to protect and maintain the confidentiality of the disclosed Confidential
Information as provided herein.

                  8.11.3. Notwithstanding the provisions of Section 8.11.1, each
Shareholder may disclose Confidential Information (i) in connection with reports
of earnings of a Shareholder, (ii) to the extent, in the opinion of such
Shareholder's legal counsel, required by the laws applicable to such
Shareholder, including without limitation, all securities laws, or (iii) in
cases involving dispute resolution under the procedures set forth in 8.10.

                  8.11.4 For purposes of this Section 8.11, the following terms
shall have the meanings given them below:

"Representatives" shall mean, with respect to any Person, such Person's owners,
stockholders, partners, directors, officers, employees, agents, consultants,
advisors (including, without limitation, auditors, engineers, financial
analysts, financial managers and attorneys), and lenders;

"Person" shall mean any natural person, any corporation, partnership, limited
liability company, trust or other entity, and any governmental or judicial
authority, body or entity;

"Affiliate" shall mean, with respect to any Person, the following: (i) any other
Person that directly, or indirectly through one or more intermediaries, controls
such Person, (ii) any other Person that is controlled by or is under common
control with such Person, or (iii) any subsidiary of such Person.

                  8.11.5. The obligations of the Shareholders under this Section
8.11 shall survive the expiration or termination of this Agreement to the
maximum extent permitted by applicable law.

                  8.11.6. To be Confidential Information, all information
disclosed in tangible form shall be conspicuously marked confidential or
proprietary at the time of initial disclosure to the recipient and information
conveyed orally shall be identified as confidential or proprietary at the time
of initial disclosure to the recipient and summarized in writing, conspicuously
marked confidential or proprietary and given to the recipient within thirty days
after the initial disclosure. Information not so identified will not be deemed
to be Confidential Information.

                  8.11.7 In the event any Shareholder is requested or required
(by deposition, interrogatories, requests for information or documents in legal
proceedings, subpoena, civil investigative demand or similar process), in
connection with any proceeding, to disclose any Confidential Information, the
Shareholder that is requested or required will give VC Holding and the other
Shareholder written notice of such request or requirement so that the
Shareholder receiving the notice or VC Holding may seek an appropriate
protective order or other remedy. In the event such protective order or other
remedy is not obtained in a timely manner, the Shareholder to whom such request
or requirement is directed will furnish only that portion of the 


                                      -21-
<PAGE>   22



Confidential Information that, in the opinion of counsel to such Shareholder, is
legally required to be disclosed and, upon the request of the other Shareholder
or VC Holding, use its best efforts to obtain assurances that confidential
treatment will be accorded to such information.

         8.12. AMENDMENTS AND WAIVERS. This Agreement may be amended, modified,
superseded, or canceled and any of its terms, covenants, representations,
warranties, undertakings, or conditions may be waived only by an instrument in
writing signed by (or by some person duly authorized by) all of the parties
hereto or, in the case of a waiver, by the party waiving compliance.

         8.13. SEVERABILITY. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration, or area of the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed.

         8.14. EXHIBITS AND SCHEDULES. The Exhibits and Schedules identified in
this Agreement are incorporated herein by reference and made a part hereof.

         8.15. PRESS RELEASES AND ANNOUNCEMENTS. No party shall issue any press
release or announcement relating to the subject matter of this Agreement without
the prior written approval of the other parties hereto; provided, however, that
any party may make any public disclosure it believes in good faith is required
by law or regulation (in which case the disclosing party will advise the other
party prior to making the disclosure).

         8.16. NO VIOLATION OF LAW. This Agreement shall not be construed to
require either party to be compelled, and no party will compel VC Holding, to do
any act or remain in any situation in violation of any law of a governmental
authority applicable to such party.

         8.17. VITRO UNDERTAKING. Vitro agrees to do such things and take such
actions so as to enable VC Holding to fulfill its obligations under this
Agreement.

         8.18. LIBBEY UNDERTAKING. Libbey agrees to do such things and take such
actions so as to enable LGA3 and VC Holding to fulfill its obligations under

                           opportunities are developed and pursued through
                           Vitrocrisa.

                           currently defined share participation in Vitrocrisa,
                           that if a business opportunity is brought by Libbey
                           relative to that certain company set forth on
                           SCHEDULE 4 hereto (the "JOINT INVESTMENT COMPANY"),

                           the other partner under a share participation of
                           Vitro of up to and including 50%; provided, however,
                           that in such a case (whether or not Vitro so
                           participates), all exports of Glass Tableware and
                           Industrial Glassware by the Joint Investment Company

                           channeled through Vitrocrisa, but the Joint
                           Investment Company may sell its Glass Tableware and
                           Industrial Glassware in its Home Country. Performance
                           criteria will be developed for the first three (3)
                           years of such distribution, which will be similar in
                           principle to the performance clause developed for
                           Libbey Glass under the Distribution Agreement where
                           Libbey serves as the exclusive distributor of
                           Vitrocrisa for Glass Tableware in the Libbey
                           Territory. After the Closing Date (as defined in the
                           Master Investment Agreement), it is understood that a
                           letter of intent will be drafted and signed by both
                           parties in which the points, positions, and desires
                           of each party relative to a future possible
                           investment opportunity with the Joint Investment
                           Company (which will be based upon the arrangements
                           relating to Vitrocrisa between the parties) are
                           clearly expressed to serve as a guideline to be used
                           in a business-like and "good faith" effort to respect
                           and accommodate them in the negotiation process at
                           that time.

         (f)      If any provision of this SECTION 3 should be found by any
                  court of competent jurisdiction to be unreasonable by reason
                  of its being too broad as to the period of time, territory,
                  and/or scope, then, and in that event, such provision will
                  nevertheless remain valid and fully effective, but will be
                  considered to be amended so that the period of time,
                  territory, and/or scope set forth will be changed to be the
                  maximum period of time, the largest territory, and/or the
                  broadest scope, as the case may be, which would be found
                  reasonable and enforceable by such court.

         (g)      Vitro acknowledges that Libbey Glass is a party to technical
                  assistance agreements with certain companies throughout the
                  world and agrees that this Agreement shall not prohibit Libbey
                  Glass from licensing and continuing to license its technology
                  throughout the world; provided, however, that Libbey Glass
                  agrees to advise and consult Vitrocrisa before entering into
                  any new license arrangement in the geographic areas set forth
                  on SCHEDULE 5 hereto or renewing any existing licenses in the
                  geographic areas set forth on SCHEDULE 5 hereto for the
                  licensing of technology and the provision of technical
                  assistance to existing and 

<PAGE>   7

                  potential licensees, but both parties agree that the ultimate
                  decision to enter into such licenses or to provide such
                  technical assistance rests in the sole and absolute discretion
                  of Libbey Glass.

         4.       ENFORCEMENT; NON-WAIVER.

         (a)      Each party hereby acknowledges and agrees that the failure of
                  it or of any of its Affiliates to perform its agreements and
                  covenants under this Agreement, including, without limitation,
                  any violation of the agreements and covenants set forth in
                  SECTION 3, will cause irreparable injury to the other party
                  and its Affiliates for which damages, even if available, will
                  not be an adequate remedy. Accordingly, each party hereby
                  consents to the issuance of injunctive relief by any court of
                  competent jurisdiction in the United States of America (or of
                  any state thereof) or of the United States of Mexico having
                  jurisdiction over it to compel performance of such party's
                  obligations and to the granting by any court of the remedy of
                  specific performance of its obligations under this Agreement,
                  in addition to any other remedy to which the other party may
                  be entitled, at law or in equity.

         (b)      A failure by either party to exercise or enforce any rights
                  conferred upon it by this Agreement shall not be deemed to be
                  a waiver of any such rights or operate so as to bar the
                  exercise or enforcement thereof at any subsequent time or
                  times, and all express rights granted to such party hereunder
                  shall be in addition to any rights that such party may have
                  under the general law in respect of a breach hereof. No waiver
                  by either party of any condition or the breach of any term,
                  covenant, representation, warranty, or undertaking contained
                  in this Agreement, whether by conduct or otherwise, in any one
                  or more instances shall be deemed to be or construed as a
                  further or continuing waiver of any such condition or breach
                  or a waiver of any other condition or deemed to be or
                  construed as the breach of any other term, covenant,
                  representation, warranty, or undertaking in this Agreement.

         Section 5.        MISCELLANEOUS.

         (a)      ENGLISH AS CONTROLLING LANGUAGE. Notwithstanding the
                  translation of this Agreement into Spanish or any other
                  language, the English language version of this Agreement shall
                  be controlling and shall govern in any legal proceeding or
                  arbitration.

         (b)      NO THIRD PARTY RIGHTS. This Agreement shall not confer any
                  rights or remedies upon any person other than the parties and
                  their respective successors and permitted assigns.

         (c)      ENTIRE AGREEMENT. This Agreement and the agreements referred
                  to herein constitute the entire agreement among the parties

         (d)      ASSIGNMENT. No party may assign or otherwise transfer any of
                  its rights or obligations under this Agreement without the
                  prior written consent of the other party. Any purported or
                  attempted assignment contrary to the terms hereof shall be
                  null and void and of no force or effect. This Agreement shall
                  be binding upon and inure to the benefit of the parties named
                  herein and their respective successors and permitted assigns.

         (e)      COUNTERPARTS. This Agreement may be executed in one or more
                  counterparts, each of which shall be deemed an original but
                  all of which together will constitute one and the same
                  instrument.

         (f)      CAPTIONS. The sections headings contained in this Agreement
                  are inserted for convenience only and are not part of this
                  Agreement and shall not affect in any way the meaning or

<PAGE>   9

                  or at any subsequent address of which Vitro may notify the
                  other parties in writing.

                  Any party hereto may change its address or telecopier number
                  for the purposes hereof by giving notice thereof to the other
                  parties in the manner provided herein.

         (h)      AMENDMENTS. This Agreement may be amended, modified,
                  superseded, or canceled and any of its terms, covenants,
                  representations, warranties, undertakings, or conditions may
                  be waived only by an instrument in writing signed by (or by
                  some person duly authorized by) all of the parties hereto or,
                  in the case of a waiver, by the party waiving compliance.

         (i)      REMEDIES. Each party to this Agreement agrees that all rights
                  and remedies under this Agreement are cumulative and that no
                  election or exercise of any right or remedy will be deemed an
                  exclusion of any other right or remedy.

         (j)      GOVERNING LAW. This Agreement will be governed by, and
                  construed in accordance with, the substantive laws of the
                  State of Texas, without giving effect to any conflicts-of-law,
                  rule, or principle that might require the application of the
                  laws of another jurisdiction.

         (k)      ARBITRATION. Any controversy or claim arising out of or
                  relating to this Agreement, or the breach thereof, shall,
                  following a demand from either party (hereinafter, the "DEMAND
                  FOR ARBITRATION") be settled by arbitration in accordance with
                  the then existing International Arbitration Rules of the
                  American Arbitration Association (hereinafter "AAA").
                  Notwithstanding the foregoing, the parties hereby agree that
                  either party may seek injunctive relief in accordance with
                  SECTION 4, and the parties further agree that if a party seeks
                  injunctive relief in accordance with SECTION 4, such party
                  does not thereby waive its rights to arbitration under this
                  SECTION 5(k).

                  The arbitral tribunal shall be composed of three arbitrators.
                  Each party, namely Libbey and Vitro, shall appoint one
                  Arbitrator. If a party fails to appoint an arbitrator within
                  thirty (30) days after the date the claimant's Demand for
                  Arbitration is communicated to the other parties (hereinafter
                  the "NOTIFICATION DATE"), the AAA shall make such appointment.
                  The two arbitrators thus appointed shall attempt to agree upon
                  the appointment of a third arbitrator to serve as chairman of
                  the arbitral tribunal. If said two arbitrators fail to agree
                  upon the appointment of such third arbitrator within sixty
                  (60) days after the Notification Date, the AAA shall make such
                  appointment. The place of arbitration shall be Dallas, Texas,
                  United States of America. The arbitral proceeding shall be
                  conducted in the English language. To the extent that they may
                  validly so agree, the parties hereby exclude any right of
                  appeal to any court in connection with the arbitral award.
                  Judgment 
<PAGE>   10

                  upon the arbitral award may be entered in any court having
                  jurisdiction thereof or having jurisdiction over either party
                  or either party's assets.

                  The validity of this SECTION 5(k) shall be governed by the
                  United Nations Convention on the Recognition and Enforcement
                  of Foreign Arbitral Awards or the Inter-American Convention on
                  International Commercial Arbitration, to which Mexico and the
                  United States of America have adhered.

                  All costs of arbitration and enforcement thereof, including
                  reasonable attorneys' fees and court costs, costs of expert
                  witnesses, transportation, lodging and meal costs of the
                  parties and witnesses, costs of transcript preparation, and
                  other reasonable and necessary direct and incidental costs
                  shall be apportioned to one or both parties by a majority of
                  the arbitrators as they deem appropriate. In the event any
                  party to this Agreement commences legal proceedings to enforce
                  the arbitral award, the expense of such litigation (including
                  reasonable attorneys' fees and costs of court) shall be borne
                  by the party not prevailing therein.

         3.1. THE SHAREHOLDERS MEETINGS; QUORUM. The shareholders meeting is the
supreme authority of Newco Finance. The shareholders meetings may be ordinary
(an "ORDINARY SHAREHOLDERS MEETING") or extraordinary (an "EXTRAORDINARY
SHAREHOLDERS MEETING"), depending on the matters to be discussed at each
meeting. They will be held at the corporate domicile of Newco Finance in
accordance with the call for the meeting made pursuant to the Crisa Libbey, S.A.
de C.V. Estatutos. According to the General Law of Mercantile Companies of
Mexico, resolutions may be adopted outside of a shareholders meeting by
unanimous vote of the Shareholders, provided that the Shareholders subsequently
confirm the adoption of such resolutions in writing to the Chairman or the
Secretary of the Newco Finance Board. An Ordinary Shareholders Meeting will be
held at least once a year within the four (4) months following the closing of
each fiscal period. Ordinary Shareholders Meetings may be those called to
discuss any of the matters that are not expressly reserved by law or this
Agreement to the Extraordinary Shareholders Meeting. The matters reserved for
Extraordinary Shareholders Meetings are:

         (a)      any matter that is required to be resolved by the
                  Extraordinary Shareholders Meeting according to Article 182 of
                  the General Law of Mercantile Companies;

         (b)      the declaration or payment of dividends pursuant to the
                  Dividend Policy; and

         (c)      any matter specified in SECTION 3.2(d) that is referred to the
                  Shareholders by the Newco Finance Board.

         An Ordinary Shareholders Meeting shall take place by virtue of a first
call of any Shareholder if the holders of fifty-five percent (55%) of the
capital stock are present or duly represented thereat. If such a quorum does not
exist for the holding of the meeting by virtue of the first call, the call shall
be repeated, and the meeting shall be considered validly held whatever number of
Shareholders are present or represented. Resolutions in Ordinary Shareholders
Meetings shall be adopted by the affirmative vote of the majority of the shares
entitled to vote that are present or represented thereat.

         An Extraordinary Shareholders Meeting shall be held by virtue of the
first call if the Shareholders holding at least seventy-five percent (75%) of
the capital stock are present or represented thereat. If such a quorum does not
exist for such meeting, the call shall be repeated, and the meeting shall be
considered validly held only with the attendance of Shareholders or their
proxies representing at least fifty-five percent (55%) of the capital stock of
Newco Finance. Resolutions in Extraordinary Shareholders Meetings held either in
first or subsequent calls shall be adopted by the affirmative vote of
Shareholders or their

representatives holding at least fifty-five percent (55%) of the capital stock
of Newco Finance.

         If holders of seventy-five percent (75%) of the capital stock are not
present or represented at the first call of any Extraordinary Shareholders
Meeting and if holders of fifty-five percent (55%) of the capital stock are not
present or represented at any repeated call of such meeting, either Shareholder
shall have the right, but shall not be obligated, to declare the occurrence of a
Deadlock Event under SECTION 6.1.

         In addition to any other requirement imposed by Mexican law, calls for
an Ordinary Shareholders Meeting of Newco Finance and calls for an Extraordinary
Shareholders Meeting of Newco Finance must be in writing and must be delivered
to each Shareholder at least fifteen (15) days prior to such meeting, unless
such notice is waived by the Shareholders in writing.

sole and absolute discretion of each Shareholder to designate, remove, or
replace the Members and alternates it has designated. Any alternate may

Group (as defined in ARTICLE IV) and no person or entity of the Vitro 100% Group

Group nor the Vitro 100% Group shall be liable to Newco Finance or any
Shareholder for breach of any fiduciary duty or duty of loyalty to Newco Finance
by reason of the fact that it pursues or acquires a Corporate Opportunity for
itself or directs a Corporate Opportunity to another person or entity. For
purposes of this section, "CORPORATE Opportunity" means a business or other
opportunity that Newco Finance is or could reasonably be expected to become
financially able to undertake, which relates to Newco Finance's line of business
and in which Newco Finance has or would have an interest or a reasonable
expectancy of interest. To the extent this SECTION 3.5 contradicts any term or
provision in the Distribution Agreement, dated of even date, by and among Vitro,
Vitrocrisa, Libbey, and Libbey Glass Inc., the Distribution Agreement, dated of
even date, by and among Vitro, Crisa Corporation, Vitrocrisa, Libbey, and Libbey
Glass Inc. (together, the "DISTRIBUTION AGREEMENTS"), or the Covenant Not to
Compete, dated of even date, by and between Libbey and Vitro (the "COVENANT NOT
TO COMPETE"), the terms and provisions of the Distribution Agreements or the
Covenant Not to Compete shall control.

such other place as the Proposing Transferor and the other Shareholder shall
agree, during normal business hours on the first business day after the
expiration of ninety (90) days after the expiration of the option period set
forth in SECTION 4.2(c).

         (e) TRANSFER ON EXPIRATION OR TERMINATION OF OPTION. If the option
granted by SECTION 4.2(c) is not exercised as to all of the Joint Venture
Interest, then such option shall become void AB INITIO and the Proposing
Transferor may sell all of the Joint Venture Interest to any third party free of
the restrictions set forth in this ARTICLE IV, subject to the following
restrictions: (i) the Joint Venture Interest may not be sold after the
expiration of one hundred eighty (180) days after the expiration of the option
period set forth in SECTION 4.2(c), (ii) the Joint Venture Interest must be sold
in a bona fide sale at a price not being less that the Prescribed Price, and
(iii) the third party transferee of the Joint Venture Interest must execute and
deliver an undertaking under which such third party shall become a party hereto,
to the Vitrocrisa Holding, S.A. de C.V. Shareholders Agreement dated of even
date (the "VC HOLDING SHAREHOLDERS AGREEMENT"), to the Vitrocrisa, S.A. de C.V.
Shareholders Agreement dated of even date (the "VITROCRISA SHAREHOLDERS
AGREEMENT"), and to the Limited Liability Company Agreement of Crisa Industrial,
L.L.C. dated of even date (the "LLC AGREEMENT," and collectively with this
Agreement, the VC Holding Shareholders Agreement, and the Vitrocrisa
Shareholders Agreement, the "JOINT VENTURE SHAREHOLDERS AGREEMENTS") in place of
the Proposing Transferor.

         (f) EXERCISE. An option granted by SECTION 4.2(c) may be exercised only
by the holder thereof and only by the delivery of a written notice of exercise
to the Proposing Transferor prior to the expiration of the relevant option
period.

         (g) WAIVER. The restrictions imposed by this ARTICLE IV may be waived
in relation to any proposed transfer of a Shareholder's Joint Venture Interest
with the consent of all Shareholders who would otherwise have been entitled to
have such Joint Venture Interest offered to them in accordance herewith.


                                      -9-
<PAGE>   10

         (h) FAILURE TO TIMELY EXERCISE. Failure of a Shareholder to exercise an
option granted by SECTION 4.2(C) prior to the expiration of the option period
shall be deemed to be a waiver of that option as of the date the option period
expired. The waiver of an option granted by SECTION 4.2(c) will not constitute a
waiver of any subsequent option granted by SECTION 4.2(c).

         (i) INTRA-GROUP TRANSFERS. Notwithstanding the foregoing, all, but not
less than all, of a Shareholder's Joint Venture Interest may be transferred to
any member of the Vitro 100% Group (in the case of Vitro) and to any member of
the Libbey 100% Group (in the case of LGA3), but only (i) if the transferee is
already a party to each of the Joint Venture Shareholders Agreements or shall
have first agreed to adhere to and be bound by the provisions of each of the
Joint Venture Shareholders Agreements by executing and delivering in favor of
the other parties to each of the Joint Venture Shareholders Agreements an
undertaking to the intent and with the effect that from the date of such
undertaking, or, if later, the date of the transfer, the transferee shall become
a party to each of the Joint Venture Shareholders Agreements, in place of the
transferor, to the extent that the transferor ceases to hold shares in Newco
Finance, Vitrocrisa, VC Holding, and the LLC as a result of such transfer; and
(ii) on terms that the transferee shall re-transfer the relative Joint Venture
Interest to a member of the Vitro 100% Group (in the case of Vitro) or to a
member of the Libbey 100% Group (in the case of LGA3) on the same terms as set
forth in SECTION 4.2(i), prior to such transferee ceasing to be a member of the
Vitro 100% Group or the Libbey 100% Group (as the case may be).

         (j) OPTION TO PARTICIPATE IN SALE. In lieu of exercising the option
granted in SECTION 4.2(c), a Shareholder may elect to participate in any sale by
the Proposing Transferor contemplated by SECTION 4.2 at the Prescribed Price.
Upon such election, the Shareholder will be entitled to sell all of its Joint
Venture Interest. The election to participate in a sale must be in writing and
must be delivered to the Proposing Transferor within thirty (30) days of receipt
of the Transfer Notice. Failure to timely deliver a written election to
participate in a sale within thirty (30) days of the Transfer Notice will
constitute a waiver of such Shareholder's right to participate in the sale.

         5.1. CAUSES OF TERMINATION. Except as otherwise provided in this
Agreement, this Agreement shall terminate:

         (a)      upon the unanimous written consent of the parties hereto;

         (b)      if Newco Finance is declared bankrupt, has a receiver
                  appointed over all or substantially all of its assets, or is
                  dissolved; or

         (c)      by decree of a court of competent jurisdiction.

         5.2. EVENTS OF DEFAULT. The occurrence of any of the following events
shall constitute an event of default ("EVENT OF DEFAULT") hereunder on the part
of the Shareholder with respect to whom such event occurs (the "DEFAULTING
PARTY") without any requirement of notice or passage of time except as
specifically set forth in any such subparagraph:

         (a)      the violation by a Shareholder or Libbey of any of the
                  restrictions set forth in ARTICLE IV;

         (b)      failure of a Shareholder's Member of the Newco Finance Board
                  to vote for and use reasonable efforts to implement the
                  Dividend Policy as set forth in SECTION 2.2;

         (c)      the institution by a Shareholder or Libbey of a case or other
                  proceeding in bankruptcy;

         (d)      the institution against a Shareholder or Libbey of a case or
                  other proceeding in bankruptcy, which proceeding is not
                  dismissed, stayed, or discharged within a period of sixty (60)
                  days after the filing thereof;

         (e)      a proposed plan of arrangement or other action by a
                  Shareholder's or Libbey's creditors taken as a result of a
                  general meeting of the creditors of a Shareholder or Libbey,
                  respectively, which arrangement or other action is not
                  dismissed, stayed, or discharged within a period of sixty (60)
                  days after such general meeting;

         (f)      the appointment of a receiver, custodian, trustee, or like
                  officer, to take possession of the assets of a Shareholder or
                  Libbey if the pendency of said receivership would reasonably
                  tend to have a materially adverse effect upon the performance
                  by the Shareholder or Libbey, respectively, of its obligations
                  under this Agreement, which receivership remains undischarged
                  for a period of sixty (60) days from the date of its
                  imposition;

         (g)      attachment, execution, or other judicial seizure of all or any
                  substantial part of a Shareholder's or Libbey's assets or of a
                  Shareholder's or Libbey's shares of Newco Finance, or any part
                  thereof, such attachment, execution, or seizure remaining
                  undismissed or undischarged for a period of sixty (60) days
                  after the levy thereof, if the occurrence of such attachment,
                  execution, or other judicial seizure would reasonably tend to
                  have a materially adverse effect upon the performance by the
                  Shareholder or Libbey, respectively, of its obligations under
                  this Agreement; provided, however, that said attachment,
                  execution, or seizure shall not constitute an Event of Default
                  hereunder if the Shareholder or Libbey, respectively, posts a
                  bond sufficient to fully satisfy the amount of such claim or
                  judgment within sixty (60) days after the levy thereof and the
                  respective Shareholder's or Libbey's assets are thereby
                  released from the lien of such attachment;

         (h)      material default in performance of or a failure to comply with
                  any obligations or undertakings of a Shareholder or Libbey
                  under the Covenant Not to Compete dated 


                                      -11-
<PAGE>   12

                  of even date by and between Vitro and Libbey, and such default
                  continues for a period of thirty (30) days following notice of
                  such default by another Shareholder;

         (i)      the occurrence of an Event of Default (as defined therein)
                  under ARTICLE V of the VC Holding Shareholders Agreement or
                  under ARTICLE V of the Vitrocrisa Shareholders Agreement or
                  under ARTICLE XII of the LLC Agreement; and

         (j)      the occurrence of a Libbey Change of Control or a Vitro Change
                  of Control (each as defined in SECTION 5.6 below).

         5.3. REMEDY ON DEFAULT. If an Event of Default is declared pursuant to
(a) SECTION 5.2(b) with respect to dividends to be paid for the performance of
Newco Finance during fiscal years 1998, 1999, and 2000 or (b) SECTION 5.2(j)
with respect to a Libbey Change of Control or a Vitro Change of Control
occurring on or before the third anniversary of this Agreement, then such
Shareholder may, in addition to any other remedy at law or in equity, invoke the
provisions of SECTION 5.5. If an Event of Default is declared at any time (a) by
a Shareholder pursuant to any other subsection of SECTION 5.2, (b) by any party
to this Agreement pursuant to SECTION 5.2(b) with respect to dividends to be
paid for the performance of Newco Finance after fiscal year 2000, or (c) by a
Shareholder pursuant to SECTION 5.2(j) with respect to a Libbey Change of
Control or a Vitro Change of Control occurring after the third anniversary of
this Agreement, then such Shareholder may, in addition to any other remedy at
law or in equity, invoke the provisions of SECTION 5.4.

         5.4. BUY/SELL PROVISION. Within forty-five (45) days of an Event of
Default the non-defaulting party (the "OFFERING SHAREHOLDER") may deliver a
written offer (the "OFFER") to purchase all, but not less than all, of the other
Shareholder's Joint Venture Interest at a cash purchase price (the "OFFER
PRICE"), fully payable on or before sixty (60) days after notice of the Offer.
Within thirty (30) days after receipt of the Offer, the other Shareholder may
notify the Offering Shareholder in writing that it will either (i) sell to the
Offering Shareholder all, but not less than all, of its Joint Venture Interest
at the Offer Price on or before the sixtieth day after receipt of the Offer or
(ii) buy from the Offering Shareholder all, but not less than all, of the
Offering Shareholder's Joint Venture Interest at (A) if Vitro is the Offering
Shareholder, 51/49 of the Offer Price or (B) if LGA3 is the Offering
Shareholder, 49/51 of the Offer Price (the "ADJUSTED OFFER PRICE"), on or before
the sixtieth day after receipt of the Offer. If the other Shareholder fails to
notify the Offering Shareholder within the thirty (30) day period that it will
(i) sell all of its Joint Venture Interest to the Offering Shareholder at the
Offer Price or (ii) buy all of the Joint Venture Interest from the Offering
Shareholder at the Adjusted Offer Price, then the Offering Shareholder must
purchase in cash all, but not less than all, of the other Shareholder's Joint
Venture Interest at the Offer Price, and the other Shareholder must sell all,
but not less than all, of its Joint Venture Interest at the Offer Price, on or
before the sixtieth day after notice of the Offer. Upon the purchase or sale of
shares pursuant to this SECTION 5.4, this Agreement shall automatically
terminate without further action by either Shareholder. Failure by the
non-defaulting party to deliver an Offer within forty-five (45) days of notice
of an Event of Default shall constitute a waiver of such party's rights under
this SECTION 5.4 with respect to the particular Event of Default.

         5.5.     DISPUTE RESOLUTION; PUT/CALL OPTION.

         (a) DISPUTE RESOLUTION. If an Event of Default is declared by a
Shareholder pursuant to (i) SECTION 5.2(b) with respect to dividends to be paid
for the performance of Newco Finance during fiscal years 1998, 1999 and 2000 or
(ii) SECTION 5.2(j) with respect to a Libbey Change of Control or a Vitro Change
of Control occurring on or before the third anniversary of this Agreement, such
Shareholder shall promptly (but in no event later than thirty (30) days after
such Shareholder's knowledge of such Event of Default) send notice of such Event
of Default to the other Shareholder (the "DEFAULT NOTICE"). Upon receipt of the
Default Notice, the alleged defaulting party will have thirty (30) days to cure
such default. If the default is not cured within such thirty (30) day period or
if the party receiving the Default Notice contests that a default has occurred,
the chief executive officers of Libbey and Vitro (collectively, the "CEOS")
shall meet within ninety (90) days of the expiration of the cure period in a
good faith effort to resolve the Event of Default. If the Event of Default is
not resolved within such ninety (90) day period, the CEOs may select an
independent mediator and subject the dispute to non-binding mediation, which
must take place within thirty (30) days of the expiration of such ninety (90)
day period. If both CEOs do not consent to non-binding mediation or if the
mediation fails to resolve the Event of Default, the Event of Default shall be
submitted to binding arbitration to be conducted in accordance with the
provisions of SECTION 8.10(b), (c), (d), and (e), the sole purpose of which is
to decide whether a default exists and, if so, which Shareholder is in default.
The arbitrators will consider all issues currently in dispute between the
Shareholders and must certify their ruling in writing to each Shareholder (the
date of such certification is referred to herein as the "CERTIFICATION DATE").
If the arbitrators determine and certify that one Shareholder is in default,
then such Shareholder shall have thirty (30) days from the Certification Date to
cure the default. If the Event of Default is not cured within such thirty (30)
day period, the non-defaulting party may invoke the provisions of SECTION
5.5(b). If the arbitrators cannot resolve which party has caused the Event of
Default or determine that both Shareholders have caused the Event of Default and
so certify, then either of the Shareholders may invoke the provisions of SECTION
5.4 within thirty (30) days of the Certification Date.

         (b)      PUT/CALL OPTION WITH PENALTY.

                  (i) PUT/CALL OPTION WITH PENALTY. If the arbitrators determine
         that Vitro or any member of the Vitro 100% Group is in default and such
         default shall not be cured within thirty (30) days of the Certification
         Date, then Libbey shall have the right to sell to Vitro, and Vitro
         shall be obligated to purchase from Libbey, all, but not less than all,
         of Libbey's Joint Venture Interest at forty-nine percent (49%) of the
         Joint Venture Value (as defined below) multiplied by one hundred twenty
         percent (120%) (the "PUT OPTION"). If the arbitrators determine that
         Libbey or any member of the Libbey 100% Group is in default, then Vitro
         shall have the right to buy from Libbey, and Libbey shall be obligated
         to sell to Vitro, all, but not less than all, of Libbey's Joint Venture
         Interest at forty-nine percent (49%) of the Joint Venture Value (as
         defined below) multiplied by eighty percent (80%) (the "CALL Option").
         The Put Option and the Call Option are collectively referred to herein
         as the "OPTION."

<PAGE>   14

                  (ii) VALUATION OF THE JOINT VENTURE. If the party in default
         does not cure the Event of Default within thirty (30) days of the
         Certification Date, the non-defaulting party may request a valuation of
         the joint venture as a going concern, which will include a valuation of
         the combined businesses of VC Holding, Vitrocrisa, Newco Finance, and
         the LLC (collectively, the "JOINT VENTURE"), within thirty (30) days of
         the expiration of the cure period. Within thirty (30) days of the date
         of such request, the CEOs will meet, and each CEO will select one
         investment banker, and the two selected investment bankers will then
         select a third investment banker, for the purpose of establishing a
         value for the Joint Venture as a going concern. Upon selection, each of
         the three investment bankers will independently determine the value for
         the Joint Venture as a going concern, the average of which will be
         deemed to be the joint venture value (the "JOINT VENTURE VALUE").

                  (iii) EXERCISING OPTION. The non-defaulting party may exercise
         the Option by giving the defaulting party written notice of its intent
         to exercise the Option within thirty (30) days of the date that the
         Joint Venture Value is determined by the investment bankers.

                  (iv) CLOSING OF OPTION. The closing of the Option will take
         place at a time and place mutually agreed upon by Libbey and Vitro;
         provided, however, that in no event will the closing take place more
         than sixty (60) days from the date of the notice of exercise set forth
         in SECTION 5.5(b)(iii).

                  (v) INVESTMENT BANKER FEES. Fees and expenses incurred in
         connection with the determination of the Joint Venture Value,
         including, without limitation, investment banker fees, will be paid by
         the party in default as certified by the arbitrators; provided,
         however, that all such fees and expenses will be paid by the
         non-defaulting party if the non-defaulting party fails to exercise the
         Option.

         5.6. DEFINITION OF CHANGE OF CONTROL. In this ARTICLE V, the following
words shall bear the following meanings:

         (a) "LIBBEY CHANGE OF CONTROL" shall be deemed to have occurred when
(i) any person or entity, together with any group of controlled companies not in
the Libbey 100% Group, acquires beneficial ownership, directly or indirectly, of
shares of stock of Libbey entitling such person or entity to exercise more than
50% of the total voting power of all classes of stock of Libbey entitled to vote
in elections of directors, or (ii) Libbey sells, leases, or otherwise transfers
all or substantially all of its assets to any person or entity not in the Libbey
100% Group.

         (b) "VITRO CHANGE OF CONTROL" shall be deemed to have occurred when (i)
any person or entity, together with any group of controlled companies not in the
Vitro 100% Group, acquires beneficial ownership, directly or indirectly, of
shares of stock of Vitro entitling such person or entity to exercise more than
50% of the total voting power of all classes of stock of Vitro entitled to vote
in elections of directors, or (ii) Vitro sells, leases, or otherwise transfers
all or substantially all of its assets to any person or entity not in the Vitro
100% Group.

                                   ----------

                              Deadlock and Impasse
                              --------------------

         6.1. DEADLOCK. A "DEADLOCK EVENT" shall be deemed to occur at such time
as a Shareholder (the "NOTIFYING SHAREHOLDER") delivers to the other Shareholder
a notification in writing (the "DEADLOCK NOTICE") stating that, in the opinion
of the Notifying Shareholder, (a) the other Shareholder's CEO failed to meet
with the Notifying Shareholder's CEO to resolve a controversy or claim regarding
a business and operational decision customarily exercised by the management of
Newco Finance within the time limits set forth in SECTION 8.10(a), (b) the other
Shareholder has, or the other Shareholder's Members of the Newco Finance Board
have, deliberately prevented the occurrence of a quorum as set forth in SECTION
3.1 or SECTION 3.2(e), respectively, or (c) the Shareholders or the Newco
Finance Board are unable to reach agreement on any of the actions set forth in
SECTION 3.1(a), (b),or (c) or SECTION 3.2(d), respectively, and setting out the
reasons therefor, and there is no resolution or agreement that has been approved
by both Shareholders (which approval may be given or withheld, or made subject
to such conditions, as are determined by the Shareholders in their respective
sole and absolute discretion) within seven (7) days after delivery of the
Deadlock Notice. A Deadlock Event shall be resolved in accordance with the
provisions of this ARTICLE VI.

         6.2. RESOLUTION OF DEADLOCK. In the event of a Deadlock Event, either
Shareholder may deliver notice of a meeting of the Shareholders (an "EMERGENCY
NOTICE") to the other Shareholder, and they shall immediately meet at a time and
place mutually agreed upon or, if no time and place is agreeable, at Newco
Finance's principal place of business at 10:00 a.m. on the fifteenth (15th) day
after the date of such Emergency Notice. Notwithstanding anything in this
Agreement to the contrary, if either Shareholder does not attend such meeting,
either Shareholder may immediately invoke the provisions of SECTION 6.4.

         6.3. DECLARATION OF IMPASSE. If, at the meeting contemplated in SECTION
6.2, the Shareholders are unable to agree on a course of action to address the
reason for the meeting, any Shareholder may declare an impasse ("IMPASSE") by
giving written notice to the other Shareholder (an "IMPASSE NOTICE"). Within
twenty (20) days after receipt of such Impasse Notice, the CEOs shall meet in a
good faith effort to reach accords that will end the Impasse. If a decision is
not made by common accord that ends the Impasse within thirty (30) days after
the date that the CEOs meet, either Shareholder may declare a final Impasse
("FINAL IMPASSE") by written notice to the other Shareholder. Notwithstanding
anything in this Agreement to the contrary, if either CEO refuses to meet with
the other CEO, either Shareholder may immediately invoke the provisions of
SECTION 6.4.

         6.4. FINAL IMPASSE. Within forty-five (45) days of notice of Final
Impasse (or pursuant to the provisions of SECTIONS 6.2 or 6.3), either
Shareholder (the "OFFERING SHAREHOLDER") may deliver a written Offer to purchase
all, but not less than all, of the Joint Venture Interest held by the other
Shareholder at a cash Offer Price, fully payable on or before sixty (60) days
after notice of the Offer. Within thirty (30) days after receipt of the Offer,
the other Shareholder may notify the Offering Shareholder in writing that it
will either (a) sell to the Offering Shareholder all, but not 


                                      -15-
<PAGE>   16

less than all, of its Joint Venture Interest at the Offer Price on or before the
sixtieth day after receipt of the Offer or (b) buy from the Offering Shareholder
all, but not less than all, of the Offering Shareholder's Joint Venture Interest
at the Adjusted Offer Price on or before the sixtieth day after receipt of the
Offer. If the other Shareholder fails to notify the Offering Shareholder within
the thirty (30) day period that it will (a) sell all of its Joint Venture
Interest to the Offering Shareholder at the Offer Price per share or (b) buy all
of the Joint Venture Interest from the Offering Shareholder at the Adjusted
Offer Price, then the Offering Shareholder must purchase in cash all, but not
less than all, of the other Shareholder's Joint Venture Interest at the Offer
Price, and the other Shareholder must sell all, but not less than all, of its
joint venture interest at the Offer Price, on or before the sixtieth day after
notice of the Offer. Upon the purchase or sale of shares pursuant to this
SECTION 6.4, this Agreement shall automatically terminate without further
action. Failure by either Shareholder to deliver an Offer within forty-five (45)
days of notice of a Final Impasse shall constitute a waiver of each
Shareholder's rights under this SECTION 6.4 with respect to the particular Final
Impasse.

         7.1. INITIAL STRATEGIC PLAN. The Shareholders agree that the Initial
Strategic Plan for Newco Finance will be as set forth on EXHIBIT D to this

Initial Strategic Plan and at least forty-five (45) days prior to the end of
each subsequent calendar year, the Managing Director of Newco Finance shall
prepare a report on Newco Finance's working capital requirements and operating
budget for the next succeeding calendar year, which will contain an itemized
estimate of the sources of revenue, the cost of goods sold, selling, general,
and administrative expenses, interest expense, net income, and all expenditures
proposed to be undertaken by Newco Finance for such year (the "PROPOSED
BUDGET"). Upon preparation of the Proposed Budget, the Managing Director shall

         8.10.    DISPUTE RESOLUTION.

                  (a) The parties to this Agreement shall exert good faith
efforts to promptly resolve any controversy or claim arising out of or related
to this Agreement or the breach thereof within fifteen (15) days of receipt of
notice by one party from another party that such a controversy or claim exists.
If the parties fail to resolve such controversy or claim within such fifteen
(15) day period, they shall, unless otherwise provided in this Agreement, give
notice in writing to the CEOs, who will meet within fifteen (15) days of receipt
of such notice at a mutually acceptable time and place to attempt to resolve any
such controversy or claim. In the event the CEOs fail to meet or to resolve the
controversy or claim within such fifteen (15) day period, the controversy or
claim (other than business and operational decisions customarily exercised by
management in entities similar to Vitrocrisa) shall be settled by arbitration in
accordance with the then existing International Arbitration Rules of the
American Arbitration Association (hereinafter "AAA"), which shall commence upon
one party providing the other parties with a written demand for arbitration (the
"DEMAND FOR ARBITRATION").

                  (b) The arbitral tribunal shall be composed of three
arbitrators, and Libbey and Vitro shall each appoint one arbitrator. If Libbey
or Vitro fail to appoint an arbitrator within thirty (30) days after the date
the claimant's Demand for Arbitration is communicated to the other parties
(hereinafter the "NOTIFICATION DATE"), the AAA shall make such appointment. The
two arbitrators thus appointed shall attempt to agree upon the appointment of a
third arbitrator to serve as chairman of the arbitral tribunal. If said two
arbitrators fail to agree upon the appointment of such third arbitrator within
sixty (60) days after the Notification Date, the AAA shall make such
appointment. The place of arbitration shall be Dallas, Texas, United States of
America. The arbitral proceeding shall be conducted in the English language.

                  (c) To the extent that they may validly so agree, the parties
hereby exclude any right of appeal to any court in connection with the arbitral
award. Judgment upon the arbitral award may be entered in any court having
jurisdiction thereof or having jurisdiction over any party or any party's
assets.

                  (d) The validity of this SECTION 8.10 shall be governed by the
United Nations Convention on the Recognition and Enforcement of Foreign Arbitral
Awards or the Inter-American Convention on International Commercial Arbitration,
to which Mexico and the United States of America have adhered.

                  (e) All costs of arbitration and enforcement thereof,
including reasonable attorneys' fees and court costs, costs of expert witnesses,
transportation, lodging, and meal costs of the parties and witnesses, costs of
transcript preparation, and other reasonable and necessary direct and incidental
costs shall be apportioned to one or more of the parties by a majority of the
arbitrators as they deem appropriate. In the event any party to this Agreement
commences legal proceedings to enforce the arbitral award, the expense of such
litigation (including reasonable attorneys' fees and costs of court) shall be
borne by the party or parties not prevailing therein.

                  (f) This SECTION 8.10 will not apply to any matter that is to
be resolved pursuant to ARTICLE V or pursuant to ARTICLE VI.

         8.11.    CONFIDENTIALITY.

                  (a) Each Shareholder shall use best efforts to maintain in
confidence and protect the confidentiality of all Confidential Information and
shall not disclose any Confidential Information to any third party not
affiliated with a Shareholder without the prior written consent of the other
Shareholder, provided that each Shareholder shall be entitled to use the
Confidential Information for any and all lawful purposes relating to its
business, operations and activities, including the financing and auditing
thereof. For purposes of this Agreement "CONFIDENTIAL INFORMATION" shall mean
all confidential or proprietary information of Newco Finance relating to its
business or operations or of a Shareholder which is provided for or in
connection with the business or operations of Newco Finance, which is provided
to a Shareholder or any of their respective Representatives (as defined below)
by Newco Finance or by any other Shareholder or any of its Representatives and
identified as confidential or proprietary as required by SECTION 8.11.(f);
provided, however, that the term shall not include (i) information known to the
recipient prior to receipt thereof from the other Shareholder or from Newco
Finance in connection with this Agreement, (ii) information which, at the time
of disclosure hereunder, is already in the public domain, (iii) information
which, after disclosure hereunder, becomes part of the public domain by
publication or otherwise through no fault of the recipient, (iv) information
obtained by a recipient from a third party (not Affiliated with a Shareholder)
in lawful possession of such information which is not under a confidentiality
obligation to the Person (as defined below) from whom such information
originated, or (v) information that is independently developed without the
benefit of the Confidential Information.

                  (b) Notwithstanding the provisions of SECTION 8.11(a), each
Shareholder may disclose Confidential Information to its or its Affiliates'
respective Representatives, provided that (i) such Representative has a need to
receive such Confidential Information to perform its duties, (ii) the disclosing
Shareholder advises such Representative of the confidential nature of the
disclosed Confidential Information, and (iii) the disclosing Shareholder uses
all reasonable efforts to cause such Representative to protect and maintain the
confidentiality of the disclosed Confidential Information as provided herein.

                  (c) Notwithstanding the provisions of SECTION 8.11(a), each
Shareholder may disclose Confidential Information (i) in connection with reports
of earnings of a Shareholder, (ii) to the extent, in the opinion of such
Shareholder's legal counsel, required by the laws applicable to such
Shareholder, including without limitation, all securities laws, or (iii) in
cases involving dispute resolution under the procedures set forth in SECTION
8.10.

                  (d) For purposes of this SECTION 8.11, the following terms
shall have the meanings given them below:

         "REPRESENTATIVES" shall mean, with respect to any Person, such Person's
owners, stockholders, partners, directors, officers, employees, agents,
consultants, advisors (including, 


                                      -20-
<PAGE>   21

without limitation, auditors, engineers, financial analysts, financial managers
and attorneys), and lenders;

         "PERSON" shall mean any natural person, any corporation, partnership,
limited liability company, trust or other entity, and any governmental or
judicial authority, body or entity;

         "AFFILIATE" shall mean, with respect to any Person, the following: (i)
any other Person that directly, or indirectly through one or more
intermediaries, controls such Person, (ii) any other Person that is controlled
by or is under common control with such Person, or (iii) any subsidiary of such
Person.

                  (e) The obligations of the Shareholders under this SECTION
8.11 shall survive the expiration or termination of this Agreement to the
maximum extent permitted by applicable law.

                  (f) To be Confidential Information, all information disclosed
in tangible form shall be conspicuously marked confidential or proprietary at
the time of initial disclosure to the recipient and information conveyed orally
shall be identified as confidential or proprietary at the time of initial
disclosure to the recipient and summarized in writing, conspicuously marked
confidential or proprietary, and given to the recipient within thirty days after
the initial disclosure. Information not so identified will not be deemed to be
Confidential Information.

                  (g) In the event any Shareholder is requested or required (by
deposition, interrogatories, requests for information or documents in legal
proceedings, subpoena, civil investigative demand or similar process), in
connection with any proceeding, to disclose any Confidential Information, the
Shareholder that is requested or required will give Newco Finance and the other
Shareholder written notice of such request or requirement so that the
Shareholder receiving the notice or Newco Finance may seek an appropriate
protective order or other remedy. In the event such protective order or other
remedy is not obtained in a timely manner, the Shareholder to whom such request
or requirement is directed will furnish only that portion of the Confidential
Information that, in the opinion of counsel to such Shareholder, is legally
required to be disclosed and, upon the request of the other Shareholder or Newco
Finance, use its best efforts to obtain assurances that confidential treatment
will be accorded to such information.

         8.12. AMENDMENTS AND WAIVERS. This Agreement may be amended, modified,
superseded, or canceled and any of its terms, covenants, representations,
warranties, undertakings, or conditions may be waived only by an instrument in
writing signed by (or by some person duly authorized by) all of the parties
hereto or, in the case of a waiver, by the party waiving compliance.

         8.13. SEVERABILITY. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability shall have the 


                                      -21-
<PAGE>   22

power to reduce the scope, duration, or area of the term or provision, to delete
specific words or phrases, or to replace any invalid or unenforceable term or
provision with a term or provision that is valid and enforceable and that comes
closest to expressing the intention of the invalid or unenforceable term or
provision, and this Agreement shall be enforceable as so modified after the
expiration of the time within which the judgment may be appealed.

         8.14. EXHIBITS AND SCHEDULES. The Exhibits and Schedules identified in
this Agreement are incorporated herein by reference and made a part hereof.

         8.15. PRESS RELEASES AND ANNOUNCEMENTS. No party shall issue any press
release or announcement relating to the subject matter of this Agreement without
the prior written approval of the other parties hereto; provided, however, that
any party may make any public disclosure it believes in good faith is required
by law or regulation (in which case the disclosing party will advise the other
party prior to making the disclosure).

         8.16. NO VIOLATION OF LAW. This Agreement shall not be construed to
require either party to be compelled, and no party will compel Newco Finance, to
do any act or remain in any situation in violation of any law of a governmental
authority applicable to such party.

         8.17. VITRO UNDERTAKING. Vitro agrees to do such things and take such
actions so as to enable Newco Finance to fulfill its obligations under this
Agreement.

         8.18. LIBBEY UNDERTAKING. Libbey agrees to do such things and take such

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

         Section 7.1 GENERAL ALLOCATIONS OF PROFITS, LOSSES, DEDUCTIONS, AND
CREDITS. After giving effect to all distributions of cash or property (other
than cash or property to be distributed pursuant to ARTICLE X), Profits, Losses,
deductions, and credits for any fiscal year shall be allocated among the Members
in accordance with their Percentage Interests. Notwithstanding the preceding
sentence, the Managers are authorized to make any allocations required by
Section 1.704-1 or 1.704-2 of the Treasury Regulations in order to ensure that
the allocations of Profits, Losses, deductions, and credits pursuant to this
Agreement are respected for federal income tax purposes. It is intended that the
allocations in this SECTION 7.1 effect an allocation for federal income tax
purposes consistent with Code Section 704 and comply with any limitations or
restrictions therein.

         Section 7.2 DISTRIBUTIONS. The Managers shall make distributions in
accordance with the distribution policy attached to this Agreement as EXHIBIT C.

         Section 7.3 LIMITATIONS ON DISTRIBUTIONS. Notwithstanding any provision
to the contrary contained in this Agreement, the Company shall not make a
distribution to any Member on account of its Interest in the Company if such
distribution would violate Section 18-607 of the Delaware Act or other
applicable law.

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

         Section 8.1  BOOKS, RECORDS AND FINANCIAL STATEMENTS.

         (a) At all times during the continuance of the Company, the Company
shall maintain, at a location to be determined from time to time by the
Managers, separate books of account for the Company that shall show a true and
accurate record of all costs and expenses incurred, all charges made, all
credits made and received and all income derived in connection with the
operation of the Company's business in accordance with generally accepted
accounting principles of the United States of America consistently applied
("U.S. GAAP"), and, to the extent inconsistent therewith, in accordance with
this Agreement. Such books of account, together with a certified copy of this
Agreement and of the Certificate, shall at all times be maintained, at a
location to be determined from time to time by the Managers, and shall be open
to inspection and examination at reasonable times by each Member and its duly
authorized representative for any purpose reasonably related to such Member's
Interest in the Company. The books of account and the records of the Company may
be examined by and reported upon as of the end of each Fiscal Year by a firm of
independent certified public accountants selected by the Managers.

         (b) The Managers shall prepare and maintain, or cause to be prepared
and maintained, the books of account of the Company and within three (3) months
after the close of each Fiscal 


                                       11

Year, the Managers shall transmit to each Member a statement indicating such
Member's share of each item of Company income, gain, loss, deduction, or credit
for such Fiscal Year for income tax purposes.

         Section 8.2 ACCOUNTING METHOD. For both financial and tax reporting
purposes and for purposes of determining Profits and Losses, the books and
records of the Company shall be kept in accordance with U.S. GAAP.

         Section 8.3 TAX MATTERS PARTNER. The Members shall designate one Member
to be the "tax matters partner" of the Company pursuant to Section 6231(a)(7) of
the Code. Any Member that is designated "tax matters partner" shall take such
action as may be necessary to cause the other Member to become a "notice
partner" within the meaning of Section 6223 of the Code. Any Member that is
designated "tax matters partner" shall inform the other Member of all
significant matters that may come to its attention in its capacity as "tax
matters partner" by giving notice thereof on or before the fifth business day
after becoming aware thereof and, within that time, shall forward to the other
Member copies of all significant written communications it may receive in that
capacity. Any Member that is designated "tax matters partner" may not take any
action contemplated by Sections 6222 through 6232 of the Code without the
consent of the other Member, but this sentence does not require the consent of
the other Member to take any action left to the determination of an individual
Member under Sections 6222 through 6232 of the Code. The "tax matters partner"
shall provide the tax information necessary for the other Member to complete its
tax returns to the other Member within 120 days of the end of each calendar
year, or the termination of this Agreement.

         Section 8.4 TAXATION AS PARTNERSHIP. The Company shall be treated as a
partnership for U.S. federal income tax purposes. No election shall be made by
the Company or any Member for the Company to be classified as an association or
a corporation under Section 7701 of the Code and the Treasury Regulations issued
thereunder or otherwise to be excluded from the application of any of the
provisions of Subchapter K, Chapter 1 of Subtitle A of the Code or from any
similar provisions of any state tax laws. If the default classification rules
under Section 7701 of the Treasury Regulations are ever amended so as to
classify the Company as an association or corporation unless it elects
otherwise, the Managers shall cause the Company to elect to be classified as a
partnership pursuant to Section 7701 of the Treasury Regulations, as amended,
for the taxable year in which such amendment to the Code or Treasury Regulations
occurs.

         (a) Except as otherwise provided by the Delaware Act, (a) the debts,
obligations, and liabilities of the Company, whether arising in contract, tort,
or otherwise, shall be solely the debts, obligations, and liabilities of the
Company, and (b) no Member shall be obligated for any such debt, obligation, or
liability of the Company solely by reason of being a Member.

<PAGE>   13

         (b) Except as otherwise expressly required by law, a Member, in its
capacity as such, shall have no liability in excess of (i) the amount of its
Capital Contributions, (ii) its share of any assets and undistributed profits of
the Company, and (iii) the amount of any distributions wrongfully distributed to
it.

         Section 9.2 INDEMNIFICATION OF THE MANAGERS AND OFFICERS. Each Manager
and officer shall be indemnified by the Company against all liability for any
claim, demand, loss, damage, liability, or expense (including, without
limitation, amounts paid in settlement, reasonable costs of investigation, and
reasonable legal expenses) resulting from any threatened, pending, or completed
action, suit, or proceeding naming any of them as defendant by reason of acts or
omissions made or omitted in good faith within the scope of their authority as
set forth in this Agreement to the maximum extent permitted by law.

         Section 9.3 CORPORATE OPPORTUNITY. No person or entity of the Libbey
100% Group (as defined in ARTICLE XI) and no person or entity of the Vitro 100%
Group (as defined in ARTICLE XI) has any duty to communicate or offer any
Corporate Opportunity (as defined below) to the Company, and neither the Libbey
100% Group nor the Vitro 100% Group shall be liable to the Company or any Member
for breach of any fiduciary duty or duty of loyalty to the Company by reason of
the fact that it pursues or acquires a Corporate Opportunity for itself or
directs a Corporate Opportunity to another person or entity. For purposes of
this section, "CORPORATE OPPORTUNITY" means a business or other opportunity that
the Company is or could reasonably be expected to become financially able to
undertake, which relates to the Company's line of business and in which the
Company has or would have an interest or a reasonable expectancy of interest. To
the extent this SECTION 9.3 contradicts any term or provision in the
Distribution Agreement, dated of even date, by and among Vitro, Vitrocrisa,
Libbey, and Libbey Glass Inc., the Distribution Agreement, dated of even date,
by and among Vitro, Crisa, Vitrocrisa, Libbey, and Libbey Glass Inc. (together,
the "DISTRIBUTION AGREEMENTS"), or the Covenant Not to Compete, dated of even
date, by and between Libbey and Vitro (the "COVENANT NOT TO COMPETE"), the terms

shall be allowed for the orderly liquidation of the assets of the Company and
the satisfaction of liabilities to creditors so as to enable the Members to
minimize the normal losses attendant upon a liquidation; and provided, further,
that if the dissolution of the Company results from the bankruptcy or
dissolution of a Member, the liquidating trustee shall be a person approved by a
majority of the Interests of the remaining Members.

         Section 10.3 TERMINATION. The Company shall terminate when all of the
assets of the Company shall have been distributed in the manner provided for in
this ARTICLE X and the Certificate shall have been canceled in the manner
required by the Delaware Act.

Member may transfer all or any portion of its Interest or its rights under this
Agreement, or agree to do so, for a period of four (4) years from the date of
this Agreement. After such four-year period, any Member may transfer all, but

Member may transfer or otherwise sell its Interest pursuant to this ARTICLE XI
for any reason.

transfer made in accordance with this ARTICLE XI must execute this Agreement and
shall become a Member of the Company upon the transferee's execution of this
Agreement and shall have the rights and powers of the transferring Member.

         (c) ENCUMBRANCE. Except as otherwise provided in this Agreement, no
Member may encumber, mortgage, pledge, hypothecate, or place a lien or make any
disposition similar thereto (collectively, an "ENCUMBRANCE") upon all or any
portion of its Interest or its rights under this Agreement, or agree to do so,
without the prior written consent of the other Member, which consent 


                                       14

shall not be unreasonably withheld, but may be subject to such reasonable
conditions as Libbey and Vitro may require.

         (d) VIOLATION. Any purported transfer or Encumbrance in violation of
the terms of this Agreement shall be null and void and shall not be recognized
by the Company.

         (b) LIMITATION ON TRANSFERS. The right to transfer or dispose of
Interests shall (save in respect of transfers made pursuant to SECTION 11.2(i))
be subject to the restrictions set forth in this SECTION 11.2. A Member may not
transfer or dispose of its Interest unless it transfers or disposes of all of
its Joint Venture Interest. Except as provided otherwise herein, no Member may
transfer or dispose of its Joint Venture Interest (save in respect of transfers
made pursuant to SECTION 11.2(i)) without the prior written consent of the other
Member.

         (c) FIRST OPTION. Before transferring or disposing of its Interest, the
Proposing Transferor shall serve a Transfer Notice on the other Member
stipulating the Prescribed Price. Upon receipt of a Transfer Notice, the other
Member shall have the right and first option for a period of thirty (30) days to
purchase the Joint Venture Interest at the Prescribed Price.

         (d) TRANSFER ON EXERCISE OF OPTION. If the Proposing Transferor is
given notice under SECTION 11.2(c) that the other Member has exercised its
option to purchase all, but not less than all, of the Joint Venture Interest,
the Proposing Transferor shall be bound, on payment of the Prescribed Price, to
transfer the Joint Venture Interest to the Purchaser or its designees. The sale
and purchase shall be completed at the office of the Company, or at such other
place as the Proposing Transferor and the other Member shall agree, during
normal business hours on the first business day after the expiration of ninety
(90) days after the expiration of the option period set forth in SECTION
11.2(c).

         (e) TRANSFER ON EXPIRATION OR TERMINATION OF OPTION. If the option
granted by SECTION 11.2(c) is not exercised as to all of the Joint Venture
Interest, then such option shall become void AB INITIO and the Proposing
Transferor may sell all of the Joint Venture Interest to any third party free of
the restrictions set forth in this ARTICLE XI, subject to the following
restrictions: (i) the Joint Venture Interest may not be sold after the
expiration of one hundred eighty (180) days after the expiration of the option
period set forth in SECTION 11.2(c), (ii) the Joint Venture Interest must be
sold in a bona fide sale at a price not being less that the Prescribed Price,
and (iii) the third party transferee of the Joint Venture Interest must execute
and deliver an undertaking under which such third party shall become a party
hereto, to the Vitrocrisa, S.A. de C.V. Shareholders Agreement dated of even
date (the "VITROCRISA SHAREHOLDERS AGREEMENT"), to the Vitrocrisa Holding, S.A.
de C.V. Shareholders Agreement dated of even date (the "VC HOLDING SHAREHOLDERS
AGREEMENT"), and to the Crisa Libbey, S.A. de C.V. Shareholders Agreement dated
of even date (the "NEWCO FINANCE SHAREHOLDERS AGREEMENT," and collectively with
this Agreement, the Vitrocrisa Shareholders Agreement, and the VC Holding
Shareholders Agreement, the "JOINT VENTURE SHAREHOLDERS AGREEMENTS") in place of
the Proposing Transferor.

         (f) EXERCISE. An option granted by SECTION 11.2(c) of this Agreement
may be exercised only by the holder thereof and only by the delivery of a
written notice of exercise to the Proposing Transferor prior to the expiration
of the relevant option period.

         (g) WAIVER. The restrictions imposed by this ARTICLE XI may be waived
in relation to any proposed transfer of a Member's Joint Venture Interest with
the consent of all of the Members 


                                       16
<PAGE>   17

who would otherwise have been entitled to have such Joint Venture Interest
offered to them in accordance herewith.

         (h) FAILURE TO TIMELY EXERCISE. Failure of a Member to exercise an
option granted by SECTION 11.2(c) prior to the expiration of the option period
shall be deemed to be a waiver of that option as of the date the option period
expired. The waiver of an option granted by SECTION 11.2(c) will not constitute
a waiver of any subsequent option granted by SECTION 11.2(c).

         (i) INTRA-GROUP TRANSFERS. Notwithstanding the foregoing, all, but not
less than all, of a Member's Joint Venture Interest may be collectively
transferred to any member of the Vitro 100% Group (in the case of Crisa) and to
any member of the Libbey 100% Group (in the case of LGA4), but only (i) if the
transferee is already a party to each of the Joint Venture Shareholders
Agreements or shall have first agreed to adhere to and be bound by the
provisions of each of the Joint Venture Shareholders Agreements by executing and
delivering in favor of the other parties to each of the Joint Venture
Shareholders Agreements an undertaking to the intent and with the effect that
from the date of such undertaking, or, if later, the date of the transfer, the
transferee shall become a party to each of the Joint Venture Shareholders
Agreements, in place of the transferor, to the extent that the transferor ceases
to hold shares in Vitrocrisa, VC Holding, and Newco Finance and an Interest in
the Company as a result of such transfer; and (ii) on terms that the transferee
shall re-transfer the relative Joint Venture Interest to a member of the Vitro
100% Group (in the case of Crisa) or to a member of the Libbey 100% Group (in
the case of LGA4) on the same terms as set forth in this SECTION 11.2(i), prior
to such transferee ceasing to be a member of the Vitro 100% Group or the Libbey
100% Group (as the case may be).

         (j) OPTION TO PARTICIPATE IN SALE. In lieu of exercising the option
granted in SECTION 11.2(c), a Member may elect to participate in any sale by the
Proposing Transferor contemplated by SECTION 11.2 at the Prescribed Price. Upon
such election, the Member will be entitled to sell all, but not less than all,
of its Joint Venture Interest. The election to participate in a sale must be in
writing and must be delivered to the selling Member within thirty (30) days of
receipt of the Transfer Notice. Failure to timely deliver a written election to
participate in a sale within thirty (30) days of the Transfer Notice will
constitute a waiver of such Member's right to participate in the sale.

                                   -----------

         Section 12.1 CAUSES OF TERMINATION. Except as otherwise provided in
this Agreement, this Agreement shall terminate:

         (a)      upon the unanimous written consent of the Members;

                  over all or substantially all of its assets, or is dissolved;
                  or

         (c)      by decree of a court of competent jurisdiction.

         Section 12.2 EVENTS OF DEFAULT. The occurrence of any of the following
events shall constitute an event of default ("EVENT OF DEFAULT") hereunder on
the part of the Member with respect to whom such event occurs (the "DEFAULTING
PARTY") without any requirement of notice or passage of time except as
specifically set forth in any such subparagraph:

         (a)      the violation by a Member of any of the restrictions set forth
                  in ARTICLE XI;

         (b)      the institution by a Member, Libbey, or Vitro of a case or
                  other proceeding in bankruptcy;

         (c)      the institution against a Member, Libbey, or Vitro of a case
                  or other proceeding in bankruptcy, which proceeding is not
                  dismissed, stayed, or discharged within a period of sixty (60)
                  days after the filing thereof;

         (d)      a proposed plan of arrangement or other action by a Member's,
                  Libbey's, or Vitro's creditors taken as a result of a general
                  meeting of the creditors of a Member, Libbey, or Vitro,
                  respectively, which arrangement or other action is not
                  dismissed, stayed, or discharged within a period of sixty (60)
                  days after such general meeting;

         (e)      the appointment of a receiver, custodian, trustee, or like
                  officer, to take possession of the assets of a Member, Libbey,
                  or Vitro if the pendency of said receivership would reasonably
                  tend to have a materially adverse effect upon the performance
                  by the Member, Libbey, or Vitro, respectively, of its
                  obligations under this Agreement, which receivership remains
                  undischarged for a period of sixty (60) days from the date of
                  its imposition;

         (f)      attachment, execution, or other judicial seizure of all or any
                  substantial part of a Member's, Libbey's, or Vitro's assets or
                  of a Member's Interest, or any part thereof, such attachment,
                  execution, or seizure remaining undismissed or undischarged
                  for a period of sixty (60) days after the levy thereof, if the
                  occurrence of such attachment, execution, or other judicial
                  seizure would reasonably tend to have a materially adverse
                  effect upon the performance by the Member, Libbey, or Vitro,
                  respectively, of its obligations under this Agreement;
                  provided, however, that said attachment, execution, or seizure
                  shall not constitute an Event of Default hereunder if the
                  Member, Libbey, or Vitro, respectively, posts a bond
                  sufficient to fully satisfy the amount of such claim or
                  judgment within sixty (60) days after the levy thereof and the
                  respective Member's, Libbey's, or Vitro's assets are thereby
                  released from the lien of such attachment;

         (g)      the occurrence of an Event of Default (as defined therein)
                  under ARTICLE V of the Vitrocrisa Shareholders Agreement, the
                  VC Holding Shareholders Agreement, or the Newco Finance
                  Shareholders Agreement;

                                       18
<PAGE>   19

         (h)      the occurrence of a Libbey Change of Control or a Vitro Change
                  of Control (each as defined in SECTION 12.6); and

         (i)      failure of a Member's Manager to vote for and use reasonable
                  efforts to implement the Distribution Policy as set forth in
                  EXHIBIT C hereto.

         Section 12.3 REMEDY ON DEFAULT. If an Event of Default is declared at
any time by a Member pursuant to SECTION 12.2(h) with respect to a Libbey Change
of Control or a Vitro Change of Control occurring on or before the third
anniversary of this Agreement, then such Member may, in addition to any other
remedy at law or in equity, invoke the provisions of SECTION 12.5. If an Event
of Default is declared at any time by a Member pursuant to (a) SECTION 12.2(h)
with respect to a Libbey Change of Control or a Vitro Change of Control
occurring after the third anniversary of this Agreement or (b) any other
provision of SECTION 12.2, then such Member may, in addition to any other remedy
at law or in equity, invoke the provisions of SECTION 12.4.

         Section 12.4 BUY/SELL PROVISION. Within forty-five (45) days of an
Event of Default, the non-defaulting party (the "OFFERING MEMBER") may deliver a
written offer (the "OFFER") to purchase all, but not less than all, of the other
Member's Joint Venture Interest at a cash purchase price (the "OFFER PRICE"),
fully payable on or before sixty (60) days after notice of the Offer. Within
thirty (30) days after receipt of the Offer, the other Member may notify the
Offering Member in writing that it will either (a) sell to the Offering Member
all, but not less than all, of its Joint Venture Interest at the Offer Price on
or before the sixtieth day after receipt of the Offer or (b) buy from the
Offering Member all, but not less than all, of the Offering Member's Joint
Venture Interest at (A) if Crisa is the Offering Member, 51/49 of the Offer
Price or (B) if LGA4 is the Offering Member, 49/51 of the Offer Price (the
"ADJUSTED OFFER PRICE"), on or before the sixtieth day after receipt of the
Offer. If the other Member fails to notify the Offering Member within the thirty
(30) day period that it will (a) sell all of its Joint Venture Interest to the
Offering Member at the Offer Price or (b) buy all of the Joint Venture Interest
from the Offering Member at the Adjusted Offer Price, then the Offering Member
must purchase in cash all, but not less than all, of the other Member's Joint
Venture Interest at the Offer Price, and the other Member must sell all, but not
less than all, of its Joint Venture Interest at the Offer Price, on or before
the sixtieth day after notice of the Offer. Failure by the non-defaulting party
to deliver an Offer within forty-five (45) days of notice of an Event of Default
shall constitute a waiver of such party's rights under this SECTION 12.4 with
respect to the particular Event of Default.

         Section 12.5 DISPUTE RESOLUTION; PUT/CALL OPTION.

         (a) DISPUTE RESOLUTION. If an Event of Default is declared by a Member
pursuant to SECTION 12.2(h) with respect to a Libbey Change of Control or a
Vitro Change of Control occurring on or before the third anniversary of this
Agreement, such Member shall promptly (but in no event later than thirty (30)
days after such Member's knowledge of such Event of Default) send notice of such
Event of Default to the other Member (the "DEFAULT NOTICE"). Upon receipt of the
Default Notice, the alleged defaulting party will have thirty (30) days to cure
such default. If the default is not cured within such thirty (30) day period or
if the party receiving the Default Notice contests that a default has occurred,
the chief executive officers of Libbey and Vitro (collectively, the "CEOS")


                                       19
<PAGE>   20

shall meet within ninety (90) days of the expiration of the cure period in a
good faith effort to resolve the Event of Default. If the Event of Default is
not resolved within such ninety (90) day period, the CEOs may select an
independent mediator and subject the dispute to non-binding mediation, which
must take place within thirty (30) days of the expiration of such ninety (90)
day period. If both CEOs do not consent to non-binding mediation or if the
mediation fails to resolve the Event of Default, the Event of Default shall be
submitted to binding arbitration to be conducted in accordance with the
provisions of SECTION 15.9(b), (c), (d), and (e), the sole purpose of which is
to decide whether a default exists and, if so, which Member is in default. The
arbitrators will consider all issues currently in dispute between the Members
and must certify their ruling in writing to each Member (the date of such
certification is referred to herein as the "CERTIFICATION DATE"). If the
arbitrators determine and certify that one Member is in default, then such
Member shall have thirty (30) days from the Certification Date to cure the
default. If the Event of Default is not cured within such thirty (30) day
period, the non-defaulting party may invoke the provisions of SECTION 12.5(b).
If the arbitrators cannot resolve which party has caused the Event of Default or
determine that both Members have caused the Event of Default and so certify,
then either of the Members may invoke the provisions of SECTION 12.4 within
thirty (30) days of the Certification Date.

         (b)      PUT/CALL OPTION WITH PENALTY.

                  (i) PUT/CALL OPTION WITH PENALTY. If the arbitrators determine
         that Crisa or any member of the Vitro 100% Group is in default and such
         default shall not be cured within thirty (30) days of the Certification
         Date, then Libbey shall have the right to sell to Vitro, and Vitro
         shall be obligated to purchase from Libbey, all, but not less than all,
         of Libbey's Joint Venture Interest at forty-nine percent (49%) of the
         Joint Venture Value (as defined below) multiplied by one hundred twenty
         percent (120%) (the "PUT OPTION"). If the arbitrators determine that
         LGA4 or any member of the Libbey 100% Group is in default, then Vitro
         shall have the right to buy from Libbey, and Libbey shall be obligated
         to sell to Vitro, all, but not less than all, of Libbey's Joint Venture
         Interest at forty-nine percent (49%) of the Joint Venture Value (as
         defined below) multiplied by eighty percent (80%) (the "CALL Option").
         The Put Option and the Call Option are collectively referred to herein
         as the "OPTION."

                  (ii) VALUATION OF THE JOINT VENTURE. If the party in default
         does not cure the Event of Default within thirty (30) days of the
         Certification Date, the non-defaulting party may request a valuation of
         the joint venture as a going concern, which will include a valuation of
         the combined businesses of Vitrocrisa, VC Holding, Newco Finance, and
         the Company (collectively, the "JOINT Venture"), within thirty (30)
         days of the expiration of the cure period. Within thirty (30) days of
         the date of such request, the CEOs will meet, and each CEO will select
         one investment banker, and the two selected investment bankers will
         then select a third investment banker, for the purpose of establishing
         a value for the Joint Venture as a going concern. Upon selection, each
         of the three investment bankers will independently determine the value
         for the Joint Venture as a going concern, the average of which will be
         deemed to be the joint venture value (the "JOINT VENTURE VALUE").

                                       20
<PAGE>   21

                  (iii) EXERCISING OPTION. The non-defaulting party may exercise
         the Option by giving the defaulting party written notice of its intent
         to exercise the Option within thirty (30) days of the date that the
         Joint Venture Value is determined by the investment bankers.

                  (iv) CLOSING OF OPTION. The closing of the Option will take
         place at a time and place mutually agreed upon by Libbey and Vitro;
         provided, however, that in no event will the closing take place more
         than sixty (60) days from the date of the notice of exercise set forth
         in SECTION 12.5(b)(iii).

                  (v) INVESTMENT BANKER FEES. Fees and expenses incurred in
         connection with the determination of the Joint Venture Value,
         including, without limitation, investment banker fees, will be paid by
         the party in default as certified by the arbitrators; provided,
         however, that all such fees and expenses will be paid by the
         non-defaulting party if the non-defaulting party fails to exercise the
         Option.

         Section 12.6 DEFINITION OF CHANGE OF CONTROL. In this ARTICLE XII, the
following words shall bear the following meanings:

         (a) "LIBBEY CHANGE OF CONTROL" shall be deemed to have occurred when
(i) any person or entity, together with any group of controlled companies not in
the Libbey 100% Group, acquires beneficial ownership, directly or indirectly, of
shares of stock of Libbey entitling such person or entity to exercise more than
50% of the total voting power of all classes of stock of Libbey entitled to vote
in elections of directors, or (ii) Libbey sells, leases or otherwise transfers
all or substantially all of its assets to any person or entity not in the Libbey
100% Group.

         (b) "VITRO CHANGE OF CONTROL" shall be deemed to have occurred when (i)
any person or entity, together with any group of controlled companies not in the
Vitro 100% Group, acquires beneficial ownership, directly or indirectly, of
shares of stock of Vitro entitling such person or entity to exercise more than
50% of the total voting power of all classes of stock of Vitro entitled to vote
in elections of directors, or (ii) Vitro sells, leases or otherwise transfers
all or substantially all of its assets to any person or entity not in the Vitro
100% Group.

                              Deadlock and Impasse
                              --------------------

         Section 13.1 DEADLOCK. A "DEADLOCK EVENT" shall be deemed to occur at
such time as a Member (the "NOTIFYING MEMBER") delivers to the other Member a
notification in writing (the "DEADLOCK NOTICE") stating that, in the opinion of
the Notifying Member, (a) the other Member's CEO failed to meet with the
Notifying Member's CEO to resolve a controversy or claim regarding a business or
operational decision customarily exercised by the management of entities similar
to the Company within the time limits set forth in SECTION 15.9(a), (b) the
other Member has, or the other Member's Managers have, deliberately prevented
the occurrence of a quorum as set forth in SECTION 5.2 or SECTION 6.5,
respectively, or (c) the Members or the Managers are unable to reach agreement
on any of the actions set forth in SECTION 5.1(a) or SECTION 6.4, respectively,
and setting 


                                       21

out the reasons therefor, and there is no resolution or agreement that has been
approved by both Members (which approval may be given or withheld, or made
subject to such conditions, as are determined by the Members in their respective
sole and absolute discretion) within seven (7) days after delivery of the
Deadlock Notice. A Deadlock Event shall be resolved in accordance with the
provisions of this ARTICLE XIII.

         Section 13.2 RESOLUTION OF DEADLOCK. In the event of a Deadlock Event,
either Member may deliver notice of a meeting of the Members (an "EMERGENCY
NOTICE") to the other Member, and they shall immediately meet at a time and
place mutually agreed upon or, if no time and place is agreeable, at the
Company's principal place of business at 10:00 a.m. on the fifteenth (15th) day
after the date of such Emergency Notice. Notwithstanding anything in this
Agreement to the contrary, if either Member does not attend such meeting, either
Member may immediately invoke the provisions of SECTION 13.4.

         Section 13.3 DECLARATION OF IMPASSE. If, at the meeting contemplated in
SECTION 13.2, the Members are unable to agree on a course of action to address
the reason for the meeting, any Member may declare an impasse ("IMPASSE") by
giving written notice to the other Member (an "IMPASSE NOTICE"). Within twenty
(20) days after receipt of such Impasse Notice, the CEOs shall meet in a good
faith effort to reach accords that will end the Impasse. If a decision is not
made by common accord that ends the Impasse within thirty (30) days after the
date that the CEOs meet, either Member may declare a final Impasse ("FINAL
IMPASSE") by written notice to the other Member. Notwithstanding anything in
this Agreement to the contrary, if either CEO refuses to meet with the other
CEO, either Member may immediately invoke the provisions of SECTION 13.4.

         Section 13.4 FINAL IMPASSE. Within forty-five (45) days of notice of
Final Impasse (or pursuant to the provisions of SECTIONS 13.2 or 13.3), either
Member (the "OFFERING MEMBER") may deliver a written Offer to purchase all, but
not less than all, of the Joint Venture Interest held by the other Member at a
cash Offer Price, fully payable on or before sixty (60) days after notice of the
Offer. Within thirty (30) days after receipt of the Offer, the other Member may
notify the Offering Member in writing that it will either (a) sell to the
Offering Member all, but not less than all, of its Joint Venture Interest at the
Offer Price on or before the sixtieth day after receipt of the Offer or (b) buy
from the Offering Member all, but not less than all, of the Offering Member's
Joint Venture Interest at the Adjusted Offer Price on or before the sixtieth day
after receipt of the Offer. If the other Member fails to notify the Offering
Member within the thirty (30) day period that it will (a) sell all of its Joint
Venture Interest to the Offering Member at the Offer Price or (b) buy all of the
Joint Venture Interest from the Offering Member at the Adjusted Offer Price,
then the Offering Member must purchase in cash all, but not less than all, of
the other Member's Joint Venture Interest at the Offer Price, and the other
Member must sell all, but not less than all, of its Joint Venture Interest at
the Offer Price, on or before the sixtieth day after notice of the Offer.
Failure by either Member to deliver an Offer within forty-five (45) days of
notice of a Final Impasse shall constitute a waiver of each Member's rights
under this SECTION 13.4 with respect to the particular Final Impasse.

         Section 14.1 SUBMISSION OF ANNUAL OPERATING BUDGET. At least forty-five
(45) days prior to the end of the calendar year beginning with November 16,
1997, the Chief Financial Officer of the Company (the "CFO") shall prepare a
report on the Company's working capital requirements and operating budget for
the next succeeding calendar year, which will substantially contain an estimate
or projection of (a) working capital requirements, including a breakout of
accounts receivable, inventory, and accounts payable, (b) sources of revenue (by
geographic area, ware type, trade areas, or established areas of distribution),
(c) the cost of goods sold, (d) selling, general, and administrative expense
detail, (e) interest expense, (f) an income statement, balance sheet, and

proposed to be undertaken by the Company for such year (the "PROPOSED BUDGET").
Upon preparation of the Proposed Budget, the CFO shall promptly submit the
Proposed Budget to the Managers for consideration.

         Section 14.2 APPROVAL OF ANNUAL OPERATING BUDGET. Promptly after
receipt of the Proposed Budget, but in any event not less than thirty (30) days
prior to the end of the calendar year, the Managers shall meet to review the
Proposed Budget. Upon such review, the Managers will vote on the Proposed
Budget. If the Proposed Budget is approved by Extraordinary Managers Action, the
Proposed Budget shall become the Company's operating budget for the next
succeeding calendar year. If the Proposed Budget is not approved by
Extraordinary Managers Action, the CFO will revise the Proposed Budget as soon
as possible and resubmit it to the Managers for consideration by Extraordinary
Managers Action. The operating budget for the previous calendar year shall
continue to govern the operations of the Company (but revised to the extent the
Members agree) until such time as a Proposed Budget is approved by the Managers
by Extraordinary Managers Action.

         Section 15.3 BINDING EFFECT. This Agreement shall be binding upon and

Agreement, their successors, legal representatives, and assigns.

         Section 15.4 SEVERABILITY. Any term or provision of this Agreement that

hereof or the validity or enforceability of the offending term or provision in

invalid or unenforceable, the parties agree that the court making the
determination of invalidity or unenforceability shall have the power to reduce
the scope, duration, or area of the term or provision, to delete specific words
or phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to

time within which the judgment may be appealed.

have formed the Company under the Delaware Act and expressly do not intend
hereby to form a partnership under either the State Uniform Partnership Act nor
the State Uniform Limited Partnership Act. The Members do not intend to be
partners one to another or partners as to any third party. To the extent any

representation shall be liable to any other Member who incurs liability by
reason of such wrongful representation.

         Section 15.9 DISPUTE RESOLUTION.

                  (a) The Members shall exert good faith efforts to promptly
resolve any controversy or claim arising out of or related to this Agreement or
the breach thereof within fifteen (15) days of receipt of notice by one Member
from another Member that such a controversy or claim exists. If the Members fail
to resolve such controversy or claim within such fifteen (15) day period, they
shall, unless otherwise provided in this Agreement, give notice in writing to
the CEOs, who will meet within fifteen (15) days of receipt of such notice at a
mutually acceptable time and place to attempt to resolve any such controversy or
claim. In the event the CEOs fail to meet or to resolve the controversy or claim
within such fifteen (15) day period, the controversy or claim (other than
business and operational decisions customarily exercised by management in
entities similar to the Company) shall be settled by arbitration in accordance
with the then existing International Arbitration Rules of the American
Arbitration Association (hereinafter "AAA"), which shall commence upon one
Member providing the other Member with a written demand for arbitration (the
"DEMAND FOR ARBITRATION").

                  (b) The arbitral tribunal shall be composed of three
arbitrators, and LGA4 and Crisa shall each appoint one arbitrator. If LGA4 or
Crisa fails to appoint an arbitrator within thirty (30) days after the date the
claimant's Demand for Arbitration is communicated to the other Member
(hereinafter the "NOTIFICATION Date"), the AAA shall make such appointment. The
two arbitrators thus appointed shall attempt to agree upon the appointment of a
third arbitrator to serve as chairman of the arbitral tribunal. If said two
arbitrators fail to agree upon the appointment of such third arbitrator within
sixty (60) days after the Notification Date, the AAA shall make such
appointment. The place of arbitration shall be Dallas, Texas, United States of
America. The arbitral proceeding shall be conducted in the English language.

                  (c) To the extent that they may validly so agree, the Members
hereby exclude any right of appeal to any court in connection with the arbitral
award. Judgment upon the arbitral award may be entered in any court having
jurisdiction thereof or having jurisdiction over any Member or any Member's
assets.

                  (d) The validity of this SECTION 15.9 shall be governed by the
United Nations Convention on the Recognition and Enforcement of Foreign Arbitral
Awards or the Inter-American Convention on International Commercial Arbitration,
to which Mexico and the United States of America have adhered.

                  (e) All costs of arbitration and enforcement thereof,
including reasonable attorneys' fees and court costs, costs of expert witnesses,
transportation, lodging, and meal costs of the Members and witnesses, costs of
transcript preparation, and other reasonable and necessary direct and incidental
costs shall be apportioned to one or more of the Members by a majority of the
arbitrators as they deem appropriate. In the event any Member commences legal
proceedings to enforce the arbitral award, the expense of such litigation
(including reasonable attorneys' fees and costs of court) shall be borne by the
Member not prevailing therein.

         Section 15.10 AMENDMENTS. Except as otherwise provided in this
Agreement, this Agreement may be amended by, and only by, a written instrument
executed by all the Members; provided, however, that no amendment shall be made,
and any such purported amendment shall be void and ineffective, to the extent
the result thereof would be to cause the Company to be treated as anything other
than a partnership for purposes of United States income taxation.

         Section 15.11 NO THIRD-PARTY BENEFICIARIES. This Agreement shall not
confer any rights or remedies upon any person other than the parties and their
respective successors and permitted assigns.

                  (b) Notwithstanding the provisions of SECTION 15.14(a), each

proceedings, subpoena, civil investigative demand or similar process), in
connection with any proceeding, to disclose any Confidential Information, the
Member that is requested or required will give the Company and the other Member
written notice of such request or requirement so that the Member receiving the
notice or the Company may seek an appropriate protective order or other remedy.
In the event such protective order or other remedy is not obtained in a timely
manner, the Member to whom

North America, Central America, and South America, which manufacturing
activities were formerly carried on by Vitrocrisa as a subsidiary of Vitro.
Vitrocrisa wishes to receive certain services from Affiliates of Libbey which
Libbey and Vitro wish to be made available to Vitrocrisa. To achieve these
goals, Libbey (and certain of its subsidiaries) and Vitro (and certain of its
subsidiaries) entered into that certain Master Investment Agreement dated August
15, 1997 (the "MASTER INVESTMENT AGREEMENT"). Pursuant to the Master Investment
Agreement, Vitro will acquire 51 Series A Shares, which represents fifty-one
percent and LGA 3 Corp., a subsidiary of Libbey, will acquire 49 Series B
Shares, which represents forty-nine percent of the voting capital stock of
Vitrocrisa.

                                 R E C I T A L S

I.       Arthur H. Smith states that his principal Libbey is a corporation

                  companies in the United States of America, some of which are

         b)       That its Affiliates have the experience, necessary
                  installations and personnel properly trained to provide the
                  services material to this Contract.

II.      Roberto Rubio states on the other hand that his principal, "VITROCRISA"
         is also a Mexican corporation duly organized and constituted according
         to the laws of the land with corporate headquarters in the city of
         Monterrey, Nuevo Leon.

         a)       That its corporate objective is the production and sale of all
                  types of glass articles.

                  confidentiality obligation to Libbey or its Affiliates from
                  whom such information originated or (v) information that is
                  independently developed without the benefit of the

         days of receipt of notice by one party from another party that such a

         attempt to resolve any such controversy or claim. In the event the CEOs
         fail to meet or to resolve the controversy or claim within such fifteen
         (15) day period, the controversy or claim (other than business and

         make such appointment.

<PAGE>   9

         The two arbitrators thus appointed shall attempt to agree upon the
         appointment of a third arbitrator to serve as chairman of the arbitral
         tribunal. If said two arbitrators fail to agree upon the appointment of
         such third arbitrator within sixty (60) days after the Notification
         Date, the AAA shall make such appointment. The place of arbitration
         shall be Dallas, Texas, United States of America. The arbitral
         proceeding shall be conducted in the English language.

                  (c) To the extent that they may validly so agree, the parties
         hereby exclude any right of appeal to any court in connection with the
         arbitral award. Judgment upon the arbitral award may be entered in any
         court having jurisdiction thereof or having jurisdiction over any party
         or any party's assets.

                  (d) The validity of this SECTION EIGHTH shall be governed by
         the United Nations Convention on the Recognition and Enforcement of
         Foreign Arbitral Awards or the Inter-American Convention on
         International Commercial Arbitration, to which Mexico and the United
         States of America have adhered.

                  (e) All costs of arbitration and enforcement thereof,

         witnesses, transportation, lodging, and meal costs of the parties and

         necessary direct and incidental costs shall be apportioned to one or
         more of the parties by a majority of the arbitrators as they deem
         appropriate. In the event any party to this Agreement commences legal
         proceedings to enforce the arbitral award, the expense of such
         litigation (including reasonable attorneys' fees and costs of court)
         shall be borne by the party or parties not prevailing therein.

                              EMPLOYMENT AGREEMENT
                              --------------------

         This EMPLOYMENT AGREEMENT ("Agreement") is effective as of September 1,
1997, between LIBBEY INC., a Delaware corporation (the "Company"), and DANIEL P.
IBELE ("Employee").

                                    RECITALS
                                    --------

    A. The Company has agreed to employ Employee in the position and at the base
rate of pay set forth on Schedule 1.

    B. The Company has further agreed to provide severance benefits to Employee
upon a termination of Employee's employment resulting from certain specified
events.

                                     EVENTS

    In consideration of the foregoing, and for other good and valuable
consideration, the receipt and adequacy of which is hereby acknowledged,
Employee and the Company hereby agree as follows:

    1 . SALARY AND POSITION. The base rate of pay and job title shown on
Schedule I are correct and in accordance with Employee's understanding.

    2. AT-WILL EMPLOYMENT. Employee's employment with the Company is not for any
specified term and may be terminated by Employee or by the Company at the time
for any reason, with or without cause.

    3. NO OTHER AGREEMENTS. Employee represents and warrant that there are no
written or oral agreements, understandings or assignments, compensation
(including compensation upon termination), benefits, or any other term or
condition of employment, except as specifically set forth herein and in
Schedule II attached hereto.

    4. ENTIRE AGREEMENT. This Agreement and the agreements listed in Schedule 11
attached hereto constitute the complete agreement between Employee and the
company regarding any and all aspects of their employment relationship and
supersede any and all prior written or oral agreements, understandings or
commitments. Employee understands that no representative of the Company has been
authorized to enter into any agreement, understanding or commitment with
Employee which is inconsistent in any way with the terms of this Agreement.

    5. PROHIBITION AGAINST AMENDMENT. Employee's base salary may be modified by
the Company at any time in its sole discretion. The retirement and benefit plans
set forth in
<PAGE>   2

Schedule II attached hereto with respect to which Employee is entitled to
participate in may be improved, reduced or terminated by the Company at any time
in its sole discretion;

provided, however, that no vested or accrued benefit shall be adversely
affected. All terms set forth in this Agreement, including without limitation
the terms set forth in paragraph 2 hereof, may not be modified in any way except
by a written agreement signed by Employee and by an authorized representative of
the Company which expressly states that intention of the parties to modify the
terms of this Agreement.

                6.  SEVERANCE PAYMENT.

         (a) Upon the termination of Employee's employment as a result of
Employee's electing to resign his employment without the consent of the Company
or electing to retire other than at the request of the Company, no payments
shall be required or made pursuant to this paragraph 6.

         (b) Upon the termination of Employee's employment by the Company for
"Cause", no payments shall be required or made pursuant to this paragraph 6.
"Cause" shall mean Employee's financial dishonesty, fraud in the performance of
his duties, willful failure to perform assigned duties hereunder or the
commission of a felony.

         (c) Upon the termination of Employee's employment by the Company for
any reason other than for Cause or disability, the Company shall continue
payment of Employee's annual base salary, at the rate then in effect on the date
of such termination, for a period of one year after such date of termination.
The Company shall give 30 days written notice of any such termination which
notice shall specify the date of termination.

         (d) Upon the termination of Employee's employment as a result of the
death of Employee, the Company shall continue payment of Employee's annual base
salary, at the rate then in effect on the date of such termination, for a period
of one year after such date of termination; PROVIDED however that such payments
shall be offset by any survivor benefits, excluding life insurance proceeds,
received by Employee's spouse or other designed beneficiary under the Company's
plans, programs and policies paid in such one year period.

         (e) Upon the termination of Employee's employment as a result of his
becoming unable to perform his duties due to a disability as established by the
award of long-term disability benefits under the Company's long-term disability
plan, the Company may terminate Employee's employment by giving Employee 30 days
written notice of its intention to terminate. In such event, Company shall
continue payment of the Employee's annual base salary, at the rate then in
effect on the date of such termination, for a period of one year after such date
of termination; PROVIDED, however, that such payments shall be offset by any
disability benefits, excluding disability insurance proceeds, received by
Employee, or his legal guardian, under the Company's plans, programs and
policies paid in such one year period.

provided for hereunder and such rights as he otherwise has under the Company's
restricted Stock Plan and the Company's Stock Option Plan in circumstances of
his particular termination.
