Company and the difficulties of insuring such protection through any other
means and (iii) Buyer would not have entered into this Agreement but for the

provision or any part thereof of this Section 5.9 is invalid or

Buyer and its Affiliates shall not, and Buyer shall cause its directors,
officers, employees and Affiliates not to, directly or indirectly induce or
attempt to induce any director, officer or employee of Seller or its
Affiliates (other than the Company) to leave the employ of Seller or its
Affiliates (other than the Company), or hire any Person who is at the time
Buyer or any of its Affiliates solicits such Person for employment, a
director, officer or employee of Seller or its Affiliates (other than the
Company).

         (b) Buyer hereby specifically agrees and acknowledges that: (i) the
covenant set forth in this Section 6.3 is commercially reasonable and
                           -----------
reasonably limited in time, scope of business and geographical scope and in
all other respects and is reasonably necessary, (ii) the covenant set forth
in this Section 6.3 is reasonably necessary in light of Seller's desire to
        -----------
protect


                                     39

<PAGE>

its legitimate interests and the difficulties of insuring such protection
through any other means and (iii) Seller would not have entered into this
Agreement but for the covenant of Buyer under this Section 6.3 and the
covenant contained herein has been made to induce Seller to enter into this
Agreement and to consummate the Contemplated Transactions. If the final
judgment of a court of competent jurisdiction declares that any term or
provision or any part thereof of this Section 6.3 is invalid or
                                      -----------
unenforceable because it is more extensive (whether as to time period,
geographic area, scope of business or otherwise) than is deemed reasonable
in the circumstances, Buyer, Vitro and Seller agree that such term or
provision shall not be void and the court making the determination of
invalidity or unenforceability shall have the power to reduce the time
period, scope of business, geographic 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.

         (c) Buyer recognizes and affirms that any breach of any provision
of this Section 6.3 will result in irreparable harm for which money damages
        -----------
would be inadequate and Seller would have no adequate remedy at law.
Accordingly, Buyer agrees that in the event of a breach or a threatened
breach by Buyer or any of its Affiliates of any of the provisions of this
Section 6.3, Seller, in addition and supplementary to other rights and
-----------
remedies existing in its favor, shall be entitled to seek from any court of
law or equity of competent jurisdiction specific performance and/or
injunctive or other relief in order to enforce or prevent any violations of
the provisions hereof (without posting a bond or other security).

6.4      APPROVAL ORDER.
         --------------

         As soon as practicable following the execution of this Agreement,
Buyer shall file with the Bankruptcy Court a motion seeking entry of the
Approval Order. Buyer agrees that it shall use commercially reasonable
efforts to have the Bankruptcy Court enter the Approval Order as soon as
practicable following execution of this Agreement. Seller agrees that it
shall promptly take actions, and Seller agrees to cause the Company to take
actions promptly, as are reasonably requested by Buyer to assist in
obtaining the Approval Order, including furnishing affidavits or other
documents or information for filing with the Bankruptcy Court.

6.5      NOTIFICATION.
         ------------

         Between the date of this Agreement and the Closing Date, Buyer will
promptly notify Seller in writing if Buyer obtains knowledge of (a) any fact
or condition that causes or constitutes a breach of any of Buyer's
representations and warranties as of the date of this Agreement, or (b) the
occurrence after the date of this Agreement of any fact or condition that
would (except as expressly contemplated by this Agreement) cause or
constitute a breach of any such representation or warranty had that
representation or warranty been made as of the time of the occurrence or
discovery of such fact or condition. Such notice will not affect any rights
of Seller under Article 9 and Article 10. During the same period, Buyer will
                ---------     ----------
promptly notify Seller of the occurrence of any breach of any covenant of
Buyer in this Article or of the occurrence of any event that may make the
satisfaction of any of the conditions in Article 7 impossible or unlikely.
                                         ---------

the employees of the Company. The parties and Vitro shall cooperate with the

                  -----------------
will, if a claim is to be made against a Person obligated to indemnify under
such Section (an "Indemnifying Person"), give notice to the Indemnifying
                  -------------------
Person of the assertion of such claim in writing and describing in
reasonable detail (to the extent known) the nature of the claim, the grounds
of the claim and the calculation (or an estimate) of the amount of the
claim. Thereafter, the Indemnified Person shall deliver to the Indemnifying
Person, promptly after the Indemnified Person's receipt thereof, copies of
all notices and documents (including court papers), if any, received by the
Indemnified Person relating to the Third Party Claim. An Indemnified
Person's failure to notify or delay in notifying an Indemnifying Person of a
Third Party Claim will not relieve the Indemnifying Person of any Liability
that it may have to the Indemnified Person, except to the extent that the
Indemnifying Person demonstrates that the resolution of such Third Party
Claim is prejudiced by the Indemnified Person's failure or delay to give
such notice.

         (b) If any Third Party Claim is brought against an Indemnified
Person and the Indemnified Person gives notice to the Indemnifying Person of
such Third Party Claim, the Indemnifying Person will be entitled to
participate in and, to the extent that it wishes, to assume and control the
defense of such Third Party Claim with counsel selected by the Indemnifying
Person; provided, however, that such counsel is not reasonably objected to
by the Indemnified Person (unless the Indemnifying Person is also a party to
such Proceeding and the Indemnified Person shall have been advised by
counsel that there are one or more legal or equitable defenses available to
the Indemnifying Person and that the joint representation of both parties by
the same counsel would create a conflict of interest, in which case the
Indemnified Party may, at its option, assume and control the defense of such
Third Party Claim at the Indemnifying Party's expense using counsel
reasonably satisfactory to the Indemnifying Party). If the Indemnifying
Person elects to assume the defense of any Third Party Claim, it shall
within ten Business Days after its receipt of notice of a Third Party Claim
from the Indemnified Person, notify the


                                     52

<PAGE>
<PAGE>

Indemnified Person in writing of such election. After notice from the
Indemnifying Person to the Indemnified Person of its election to assume the
defense of such Proceeding, the Indemnifying Person will not, as long as it
diligently conducts such defense, be liable to the Indemnified Person under
this Article for any fees of other counsel or any other expenses with
respect to the defense of such Proceeding, in each case subsequently
incurred by the Indemnified Person in connection with the defense of such
Proceeding, other than reasonable costs of investigation. If the
Indemnifying Person chooses to defend or prosecute a Third Party Claim, all
the Indemnified Persons shall provide reasonable cooperation in the defense
or prosecution thereof. Such cooperation shall include the retention and
(upon the Indemnifying Person's request) the provision to the Indemnifying
Person of records and information that are reasonably relevant to such Third
Party Claim, and making employees available on a mutually convenient basis
to provide additional information and explanation of any material provided
hereunder. If the Indemnifying Person assumes the defense of a Proceeding,
(i) the Indemnified Person shall agree to any reasonable settlement,
compromise or discharge of a Third Party Claim that the Indemnifying Person
may recommend and that by its terms (1) obligates the Indemnifying Person to
pay the full amount of the Liability in connection with such Third Party
Claim, (2) expressly releases in full the Indemnified Person with respect to
such Third Party Claim, (3) involves only money damages and does not seek an
injunction or other equitable relief, and (4) would not otherwise adversely
affect the Indemnified Person, and (ii) in the event that the terms of any
settlement, compromise or discharge of a Third Party Claim that the
Indemnifying Person may recommend do not release the Indemnified Person
completely in connection with such Third Party Claim or would otherwise
adversely affect the Indemnified Person, no compromise or settlement of such
claims may be effected by the Indemnifying Person without the Indemnified
Person's written consent.

         (c) If notice is given to an Indemnifying Person of the
commencement of any Third Party Claim and the Indemnifying Person does not,
within ten Business Days after the Indemnified Person's notice is given,
give notice to the Indemnified Person of its election to assume the defense
of such Third Party Claim, the Indemnifying Person will be bound by any
determination made with respect to such Third Party Claim or any compromise
or settlement effected in good faith by the Indemnified Person.

         (d) Notwithstanding the foregoing, if an Indemnified Person
determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its Affiliates other than as a result
of monetary damages for which it would be entitled to indemnification under
this Agreement, the Indemnified Person may, by notice to the Indemnifying
Person, assume the exclusive right to defend, compromise or settle such
Proceeding, but the Indemnifying Person will not be bound by any
determination of a Proceeding so defended or any compromise or settlement
effected without its consent (which may not be unreasonably withheld).

         (e) Notwithstanding the provisions of Sections 10.7(a) through
                                               ----------------
10.7(d), Buyer will be entitled to assume control of any Cleanup and related
-------
Proceeding arising from a claim relating to any Environmental, Health and
Safety Liability.

10.8     PROCEDURE FOR INDEMNIFICATION - OTHER CLAIMS.
         --------------------------------------------

         A claim for indemnification for any matter not involving a
Third-Party Claim may be asserted by notice to the party obligated to
indemnify and will be paid promptly after such notice. The foregoing
indemnification provisions are in addition to, and not in derogation of, any
statutory, equitable, or common Law remedy (including without limitation any
such remedy arising under Environmental Law or Occupational Safety and
Health Law) any party may have with respect to the Contemplated
Transactions.

10.9     CALCULATION OF LOSSES.
         ---------------------

         The amount of any Third Party Claim for which indemnification is
provided under this Article 10 shall be net of any amounts actually
                    ----------
recovered by the Indemnified Person under insurance policies with respect to
such Third Party Claim, provided, however, any increase in amounts payable
under such policies as a result of claims filed in respect of Adverse
Consequences hereunder shall be deemed to be Adverse Consequences for which
indemnification may be sought pursuant to the terms of this Agreement.

10.10    SOLE REMEDY.
         -----------

         Except as otherwise specifically provided in this Agreement and
except for claims or causes of action arising from fraud, each of Seller and
Buyer acknowledge that, following the Closing, its sole and exclusive
monetary remedy with respect to any and all claims relating to this
Agreement, and the transactions contemplated hereby shall be pursuant to the
indemnification provisions set forth in this Article 10.
                                             ----------

consistent with the accounting methods and other practices used by the
Company in preparing its prior Tax Returns. The Company will pay any Taxes
shown as due thereon.

         (b) As to Tax Returns of the Company due after the Closing Date for
tax periods ending on or before the Closing Date, Seller shall prepare (or
cause to be prepared) such Tax Returns in a manner consistent with the
accounting methods and other practices used by the Company in preparing its
prior Tax Returns; provided, however, that (i) Seller shall deliver (or
cause to be delivered) any such Tax Return to Buyer at least twenty (20)
days before it is due, (ii) Buyer shall be entitled to comment on such Tax
Return by written notice given within ten (10) Business Days after delivery

examine and comment on any such Tax Return prior to the filing thereof, and
such Tax Return will not be filed without the prior written consent of

notice of objection no later than ten (10) days before the Tax Return is

         (d) After the Closing Date, the Company shall not, without the
prior written consent of Seller, which consent shall not be unreasonably
withheld, conditioned or delayed, file any amended Tax Return for a

might be liable for additional Taxes on such Tax Return under Article 10.
The provisions set forth herein will not affect Buyer's right to
indemnification as provided in Section 10.2.
                               ------------

11.2     CHARACTERIZATION OF INDEMNITY PAYMENT.
         -------------------------------------

         All amounts paid by Buyer or Seller, as the case may be, by reason

         Seller will make available to Buyer and the Company such records as
Buyer and the Company may require for the preparation of any Tax Return and

concerning such Tax Return. Buyer and the Company will make available to
Seller such records as Seller may require for the preparation of any Tax
Return and such records as Seller may require for the defense of any
Proceeding concerning any such Tax Return.

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

         Buyer, on the one hand, and Seller, on the other hand, shall pay
equally all Transfer Taxes arising out of or in connection with the
Contemplated Transactions. Buyer shall indemnify, defend, and hold harmless

the deduction of the fiscal value of the Company's inventory as of December

claimed in good faith by the Company; provided that any refund of Taxes with
respect to a Pre-Closing Period arising from a carryback of a loss arising
for any taxable period (or portion thereof) beginning after the Closing Date
(a "Post-Closing Period") shall be deemed to be a refund arising in a
Post-Closing Period. Buyer and Seller shall cooperate, and Buyer shall cause
the Company to cooperate with Seller, in claiming any Tax refund or credit
referred to in this Section 11.7, including without limitation by notifying
Seller of the existence of any facts that would constitute a reasonable
basis for claiming such a Tax refund, providing all relevant information
available to Seller or the Company with respect to any such claim, and
filing and diligently pursuing such claim. Any refund or credit of Taxes of
the Company for a Post-Closing Period shall be for the account of the
Company. Buyer and the Company shall permit Seller or its designated
Affiliate to control the prosecution of any such Tax refund or credit claim.

12.6     INCORPORATION OF SCHEDULES AND EXHIBITS.
         ---------------------------------------

         The Schedules and Exhibits identified in this Agreement, including
Seller's Disclosure Schedule and Buyer's Disclosure Schedule, are
incorporated herein by reference and made a part of this Agreement.

12.7     ENTIRE AGREEMENT AND NEGOTIATION.
         --------------------------------

         This Agreement supersedes all prior agreements between the parties
with respect to its subject matter (including the Letter of Intent between
Buyer and Seller dated June 3, 2005) and constitutes (along with the
Ancillary Agreements and the other documents delivered pursuant to this
Agreement) a complete and exclusive statement of the terms of the agreement
between the parties with respect to its subject matter. This Agreement may
not be amended, supplemented or otherwise modified except by a written
document executed by the party against whose interest the modification will
operate.

12.8     SELLER'S DISCLOSURE SCHEDULE.
         ----------------------------

         The Seller's Disclosure Schedule is not intended to constitute, and
shall not be construed as constituting, representations or warranties of
Vitro or Seller except as and to the extent provided in this Agreement.
Inclusion of information therein shall not be construed as an admission that
such information is material to the operations or financial condition of
Vitro, Seller, or the Company.

         Matters reflected in the Seller's Disclosure Schedule are not
necessarily limited to matters required by the Agreement to be reflected in
the Seller's Disclosure Schedule. Such additional matters are set forth for
information purposes and do not necessarily include other matters of a
similar nature. Nothing in such Seller's Disclosure Schedule will be
adequate to disclose an exception to any representation or warranty made in
Article 3 or Article 4 unless the applicable Seller's Disclosure Schedule
---------    ---------
identifies the exception with reasonable particularity. Without limiting the
generality of the foregoing, the listing or inclusion of a copy of a
document or other item will not be adequate to disclose an exception to any
representation or warranty made in this Agreement unless the representation
or warranty relates to the existence of the document or item itself. In the
event of any inconsistency between the statements in the body of this
Agreement and those in such Seller's Disclosure Schedule (other than an
exception expressly set forth as such in a Seller's Disclosure Schedule with
respect to a specifically identified representation or warranty), the
statements in the body of this Agreement will control.

12.9     TIME OF ESSENCE.
         ---------------

         With regard to all dates and time periods set forth or referred to
in this Agreement, time is of the essence.

12.10    DRAFTING AND REPRESENTATION.
         ---------------------------

         The parties have participated jointly in the negotiation and
drafting of this Agreement. No provision of this Agreement will be
interpreted for or against any party because that party or its legal
representative drafted the provision.

                                     59

<PAGE>
<PAGE>

12.11    SEVERABILITY.
         ------------

         If a court of competent jurisdiction holds any provision of this
Agreement invalid or unenforceable, the other provisions of this Agreement
will remain in full force and effect. Any provision of this Agreement held
invalid or unenforceable only in part or degree will remain in full force
and effect to the extent not held invalid or unenforceable.

12.12    ASSIGNMENT; SUCCESSORS; NO THIRD-PARTY RIGHTS.
         ---------------------------------------------

         Neither party may assign any of its rights or delegate any of its
obligations under this Agreement without the prior written consent of the
other party. Subject to the preceding sentence, this Agreement will apply
to, be binding in all respects upon, and inure to the benefit of the
parties' successors and permitted assigns. Nothing expressed or referred to
in this Agreement will be construed to give any Person, other than the
parties to this Agreement, any legal or equitable right, remedy or claim
under or with respect to this Agreement or any provision of this Agreement
except such rights as may inure to a successor or permitted assignee under
this Section.

12.13    ENFORCEMENT OF AGREEMENT.
         ------------------------

         Each party acknowledges and agrees that the other could be damaged
irreparably if any of the provisions of this Agreement are not performed in
accordance with the specific terms and that any breach of this Agreement by
either party could not be adequately compensated in all cases by monetary
damages alone. Accordingly, each party agrees that, in addition to any other
right or remedy to which the other party may be entitled, at law or in
equity, it will be entitled to enforce any provision of this Agreement by a
decree of specific performance and to temporary, preliminary and permanent
injunctive relief to prevent breaches or threatened breaches of any of the
provisions of this Agreement, without posting any bond or other undertaking.

12.14    WAIVER.
         ------

         The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither any failure nor any delay by any
party in exercising any right, power or privilege under this Agreement or
any of the documents referred to in this Agreement will operate as a waiver
of such right, power or privilege, and no single or partial exercise of any
such right, power or privilege will preclude any other or further exercise
of such right, power or privilege or the exercise of any other right, power
or privilege. To the maximum extent permitted by applicable Law, (a) no
claim or right arising out of this Agreement or any of the documents
referred to in this Agreement can be discharged by one party, in whole or in
part, by a waiver or renunciation of the claim or right unless in a written
