Saint-Gobain Holdings I Corp., a Delaware corporation ("Purchaser"),
Saint-Gobain Corporation, a Pennsylvania corporation ("SGC"), and
Ball-Foster Glass Container Co., L.L.C. (formerly Foster-Ball, L.L.C.), a
limited liability company organized under the laws of the State of Delaware
(the "Company"). BGHI and BGHII are collectively referred to herein as
"Sellers"; the Company, SGC and Purchaser are collectively referred to

herein are used as defined in the LLC Agreement (as defined below).

         WHEREAS, Sellers and Purchaser are parties to that certain Amended
and Restated Limited Liability Company Agreement, dated as of June 26, 1995

Purchaser have associated themselves as members of the Company; and

         WHEREAS, Sellers are the record and beneficial owners of Interests
in the Company and Sellers desire to sell and Purchaser desires to purchase
all of Sellers' Interests (the "Seller Interests") in the Company

terms and conditions set forth herein.

         NOW, THEREFORE, in consideration of the mutual agreements
contained herein, the parties hereto agree as follows:

         1. Purchase and Sale of Seller Interests. Subject to the terms and

Purchaser will pay to Sellers at the Closing the aggregate of $190 million
in cash (the "Purchase Price"), $95 million of which shall be paid to BGHI

Section 7 hereof at 10:00 A.M., local time, or at such other time and place
as may be agreed to by the parties hereto.

         3. Deliveries at the Closing. At the Closing, (a) Sellers will

         6.  Certain Other Agreements.

             (a) Termination of Liability.

                 (i) Upon the execution of this Agreement, neither Seller
         nor any of their affiliates shall have any obligation to the
         Company under the LLC Agreement to make any capital contribution
         or other payment to the Company (including any capital
         contribution that would otherwise be due from Sellers under
         Section 3.2(d) of the LLC Agreement as a result of any Net
         Adjustment Amount) unless the Closing does not occur and this
         Agreement is terminated in accordance with its terms, in which
         case Sellers shall be obligated to make any capital contribution
         or other payment required to be made by them in accordance with
         the terms of the LLC Agreement. Except as otherwise provided in
         Section 6(c)(iv)(A) hereof, upon consummation of the Closing,
         neither Seller nor any of their respective affiliates shall have
         any liability or obligation of any kind or nature to the Company
         or its Members under the LLC Agreement and, effective as of the
         Closing, except as otherwise provided in Section 6(c)(iv)(A)
         hereof, each of SGC, SGH and the Company hereby releases and
         forever discharges each Seller and their respective affiliates
         from all of their liabilities and obligations under the LLC
         Agreement.

                 (ii) Except as otherwise provided in Sections 6(b) and
         6(c)(iv)(B) and (C) hereof, upon consummation of the Closing,
         neither the Company nor Purchaser shall have any liability or
         obligation of any kind or nature to either Seller or any of their
         respective affiliates under the LLC Agreement (including, but
         not limited to, any obligation to make any distribution or other
         payment to either Seller pursuant to Article 5 of the LLC
         Agreement) and, except as otherwise provided in Sections 6(b) and
         6(c)(iv)(B) and (C) hereof, each Seller hereby releases and
         forever discharges Purchaser, the Company and their respective
         affiliates from all of their liabilities and obligations under the
         LLC Agreement.

             (b)  Certain Tax Matters.  The Sellers' distributive

share of the Company's income or loss for the taxable year in which the
Closing takes place shall be determined based on a closing of the Company's
books as of the close of business on the last business day prior to the
Closing. Notwithstanding the sale of the Sellers Interests to Purchaser,
Sellers will receive all distributions pursuant to Section 5.1(a) of the LLC
Agreement in respect of any taxes incurred or to be incurred by Sellers or
their affiliates as a result of Sellers' ownership of interests in the Company
through the Closing and without regard to the limitations set forth in the
penultimate sentence of Section 5.1(a) of the LLC Agreement. At the Closing,
the Company will pay to Sellers in cash by wire transfer of immediately
available funds the amount of $8,377,018, representing all distributions with
respect to taxes which have not been paid as of the Closing and are required
to be paid pursuant to Section 5.1(a) of the LLC Agreement on or before the
Closing without regard to the limitations set forth in the penultimate
sentence of such Section 5.1(a). No Purchaser Entity shall have any
responsibility with respect to any federal, state or local tax of the Sellers
arising as a result of the Sale by Sellers of their Seller's Interest to
Purchaser.

             (c)  LLC Agreement.

                 (i) The parties hereto agree that notwithstanding the
         provisions of Sections 10.1(a) and 15.5 of the LLC Agreement or
         any other section of the LLC Agreement, the purchase and sale of
         the Seller Interests pursuant to this Agreement, which are not
         being consummated pursuant to the provisions of Article 10 or
         Article 11 of the LLC Agreement, are expressly permitted.

                 (ii) The parties hereto (A) acknowledge that Purchaser is
         currently a Member and therefore need not be admitted as a Member
         in connection with its purchase of the Seller Interests and (B)
         agree that the provisions of Section 10.10(c) of the LLC Agreement
         shall not apply to the purchase and sale of the Seller Interests
         pursuant to this Agreement, that the purchase by Purchaser of the
         Seller Interests will be valid without compliance with the
         provisions of Section 10.10 and that Purchaser will succeed to the
         rights and obligations of Sellers but not Ball Parent under the
         Transaction Documents.

                 (iii) Each Seller acknowledges that upon consummation of
         the Closing, such Seller shall have assigned all of its Seller
         Interests to Purchaser and, in accordance with Section 18-702 of
         the Delaware Limited Liability Company Act, 6 Del. C. ss.ss.
         18-101 et seq. and Section 10.10 of the LLC Agreement, such Seller
         shall cease to be a Member, to have any obligations or liabili-
         ties of a Member or to have the power to exercise any rights or
         powers of a Member except as provided in Section 6(c)(iv) below.

                 (iv) The parties hereto acknowledge that (A) the
         provisions of Section 9.1 of the LLC Agreement shall continue to
         be applicable to Sellers for a period of three years after the
         Closing in accordance with the terms thereof, (B) Sellers and any
         Indemnified Parties related to Sellers shall continue to be
         entitled to the benefits of Article 14 of the LLC Agreement (and
         specifically shall be indemnified and held harmless from and
         against any losses, claims, damages or expenses relating to the
         proposed acquisition by the Company of Anchor Glass Container
         Corporation, regardless of whether arising before or after the
         Closing) and (C) Sellers shall continue to be entitled to the
         benefits of Article 7 of the LLC Agreement with respect to periods
         during which Sellers were Members of the Company.

any party hereto of any representation or warranty or agreements contained
herein, such party shall be fully liable for any and all damages incurred
