                                    RECITALS

               WHEREAS, the Lenders have entered into a Secured Credit
Agreement dated as of April 23, 2001 (the "SECURED CREDIT AGREEMENT"), as
amended by that certain First Amendment to Secured Credit Agreement and Consent
dated as of December 31, 2001 (the "FIRST AMENDMENT AND CONSENT") with certain
subsidiaries of Company as Borrowers and with Company as guarantor pursuant to
Section 9 thereof and Owens-Illinois General, Inc., as Borrowers' Agent (the
Secured Credit Agreement, as so amended and as more particularly defined in the
Security Agreement, is referred to herein as the "CREDIT AGREEMENT");

               WHEREAS, the Subsidiary Guarantors entered into a Subsidiary
Guaranty of all Obligations as defined in and now or hereafter existing under or
in respect of the Credit Agreement;

               WHEREAS, the Domestic Borrowers entered into a Domestic
Borrowers' Guaranty under which each Domestic Borrower guaranteed (i) all
Revolving Loans made to, and related Obligations of, each other Domestic
Borrower; (ii) all Offshore Loans made to, and all other Obligations of, the
Offshore Borrowers; (iii) the Other Lender Guarantied Obligations; and (iv) all
Term Loans made to, and related Obligations of, each other Domestic Borrower;

               WHEREAS, the Credit Agreement permits Indebtedness from time
to time issued constituting New Senior Debt to be secured by the Domestic
Collateral (as defined in the Intercreditor Agreement) under the Domestic
Collateral Documents, including the Security Agreement;

               WHEREAS, concurrently herewith, Owens Brockway is issuing
certain 8 7/8% Senior Secured Notes due 2009 in the aggregate principal amount
of $1,000,000,000 (together with any subsequent issuance of notes consituting
the same series of notes as the 8 7/8% Senior Secured Notes due 2009 pursuant to
the same indenture on substantially identical terms the Net

                                        1
<Page>

Debt Securities Proceeds of which are applied to repay the Term Loans pursuant
to Section 2.4A(ii)(e) of the Credit Agreement or as otherwise required thereby,
in each case together with any guarantees thereof and any notes and guarantees
issued in exchange therefor or replacement thereof containing substantially
identical terms, the "NEW 2002 SENIOR NOTES") which New 2002 Senior Notes
constitute New Senior Debt (subject, with respect to any subsequent issuance of
notes (but not any exchange notes) described above, to Administrative Agent's
determination in its reasonable judgment that the terms and conditions of such
notes are substantially comparable to those prevailing in the market place for
comparable debt issuances) and desires to have such New 2002 Senior Notes
constitute Senior Secured Obligations under the Intercreditor Agreement and to
secure the obligations in respect of such New 2002 Senior Notes by certain of
the Domestic Collateral;

               WHEREAS, in order to facilitate the issuance of the New 2002
Senior Notes, Owens Brockway has obtained, pursuant to the First Amendment and
Consent, the consent of the Requisite Lenders and Requisite Obligees, as
applicable, to the Collateral Agent's amendment of the Security Agreement to
eliminate the provision of certain Securities Collateral as security for the New
2002 Senior Notes, which Securities Collateral would otherwise secure the
obligations in respect of such New 2002 Senior Notes upon their issuance and the
execution of a counterpart to the Intercreditor Agreement by the New Senior Debt
Representative and Borrower's Agent and the application of the Net Debt
Securities Proceeds arising from the issuance of the New 2002 Senior Notes to
repay the Term Loans pursuant to Section 2.4A(ii)(e) of the Credit Agreement;
and

               WHEREAS, the parties desire to amend the Security Agreement as
set forth herein to implement the provisions of the First Amendment and Consent.

               NOW, THEREFORE, in consideration of the premises and the
agreements, provisions and covenants herein contained, the parties hereto agree
as follows:

                                   SECTION 1.
                        AMENDMENTS TO SECURITY AGREEMENT

          1.1  RECITALS.

          (a)  Recital 5 of the Security Agreement is hereby amended by adding
the phrase "acting in such capacity for the benefit of the holders of New Senior
Debt" after the words "New Senior Debt" in the last sentence thereof.

          1.2  GRANT OF SECURITY.

          (a)  The initial paragraph of Section 1 of the Security Agreement is
hereby amended by adding the following parenthetical after the words "Secured
Parties": "(subject to Section 2 below with respect to the New 2002 Senior
Notes)".

          (b)  The last sentence of Section 1(e)(i) is replaced in its entirety
by the following: "As used herein, "DOMESTIC OBLIGATIONS" means the obligations
of the Domestic Borrowers consisting of Term Loans, Revolving Loans, Letters of
Credit for the account of Domestic Borrowers, the Domestic Overdraft Agreement,
any obligations of any Loan Party under other Loan Documents,

                                        2
<Page>

Other Permitted Credit Exposure Documents and New Senior Debt Documents, and
Interest Rate Obligations and Currency Obligations, in each case which are not
obligations of Offshore Borrowers or any Foreign Subsidiary, and "FOREIGN
OBLIGATIONS" means the obligations of the Offshore Borrowers and their Foreign
Subsidiaries consisting of Offshore Loans, Letters of Credit for the account of
Offshore Borrowers, the Offshore Overdraft Agreements and any obligations under
the other Loan Documents which are not obligations of a domestic entity,
including Grantors (it being understood that the intent of the foregoing
definitions and provisos is to avoid a situation in which a pledge of Foreign
Pledged Shares and a realization on, foreclosure against or recourse to such
Foreign Pledged Shares would constitute an investment of earnings in United
States property under Section 956 (or a successor provision) of the Internal
Revenue Code which would trigger an increase in the gross income of a United
States shareholder of any issuer of Foreign Pledged Shares pursuant to Section
951 (or a successor provision) of the Internal Revenue Code)."

          1.3  SECURITY FOR OBLIGATIONS. Section 2 of the Security Agreement is
hereby amended by (i) adding the following after the words "Section 1(e)" in the
first sentence thereof: "and the exclusion set forth below with respect to the
New 2002 Senior Notes"; (ii) adding the following to the end of the first
sentence thereof: "and PROVIDED, FURTHER, THAT, the Securities Collateral
described in clauses (e)(i) and (e)(ii) of the definition thereof (other than
any such Securities Collateral directly owned by or owed to Company or
Packaging)(such Securities Collateral, including, for the avoidance of doubt,
any documents, instruments or certificates evidencing same and any proceeds of
such Securities Collateral being the "EXCLUDED SECURITIES COLLATERAL") shall not
be security for or be assigned or pledged on account of the New 2002 Senior
Notes and such Excluded Securities Collateral shall not be held by Collateral
Agent for the benefit of any holder of, or New Senior Debt Representative with
respect to, such New 2002 Senior Notes"; and (iii) deleting the proviso in the
penultimate sentence thereof in its entirety and replacing it with the
following: "PROVIDED, HOWEVER, that the pledge made and security interest
granted in SECTION 1 and any other provisions of this Agreement shall be
effective as to any obligations in respect of any New Senior Debt or Other
Lender Guarantied Obligations only if the holders of such obligations or their
representatives (A) shall have executed and delivered to the Collateral Agent a
counterpart of the Intercreditor Agreement or an acknowledgment to the
Intercreditor Agreement (in the form attached thereto) and the Borrowers' Agent
has duly executed and delivered an acknowledgement to such acknowledgement and
(B) in the case of Other Lender Guarantied Obligations shall have released, in
form and substance satisfactory to Collateral Agent and Borrowers' Agent,
Holdings from any pre-existing guaranty obligations in connection with such
Other Lender Guaranteed Obligations."

          1.4  REMEDIES. The second sentence of Section 16(a) of the Security
Agreement is hereby amended by adding the following to the end thereof: "(the
foregoing limitation, however, shall not apply to Collateral Agent acting in
such capacity)".

          1.5  APPLICATION OF PROCEEDS. Clause "SECOND" of Section 18 of the
Security Agreement is hereby amended by adding the word "ratable" before the
phrase "payment of all other Secured Obligations" and striking the words
"PROVIDED that" and adding the following in their place: "PROVIDED, THAT, no
Proceeds received by Collateral Agent in respect of any sale of, collection from
or other realization upon all or any part of the Excluded Securities Collateral
shall be applied toward payment of obligations in respect of the New 2002 Senior
Notes (and

                                        3
<Page>

neither the holders of nor representatives for such New 2002 Senior Notes
shall be entitled to any increased portion of any Proceeds of any other
Collateral due to such exclusion); PROVIDED, FURTHER, THAT,"

                                   SECTION 2.
                           CONDITIONS TO EFFECTIVENESS

          2.1  This Amendment shall become effective only upon the satisfaction

of all of
the following conditions precedent (the date of satisfaction of such conditions
being referred to herein as the "FIRST AMENDMENT EFFECTIVE DATE"):

               (b) On or before the First Amendment Effective Date, all
corporate and other proceedings taken or to be taken in connection with the
transactions contemplated hereby and all documents incidental thereto not
previously found acceptable by Administrative Agent, acting on behalf of
Lenders, and its counsel shall be satisfactory in form and substance to
Administrative Agent and such counsel, and Administrative Agent and such counsel
shall have received all such counterpart originals or certified copies of such
documents as Administrative Agent may reasonably request.

                                   SECTION 3.
                         REPRESENTATIONS AND WARRANTIES
