                               Commitment Letter
                               -----------------

Dear Sirs:

          We understand that Crown Cork & Seal Company, Inc., a Pennsylvania
corporation ("CCSC"), will require a multi-currency credit facility (the
"Facility") in the amount of French Francs 13,700,000,000 (or its equivalent in
other applicable currencies).  The proceeds of the Facility will be used by CCSC
and selected non-U.S. subsidiaries (a) to pay the cash portion of the
consideration to be paid in connection with the acquisition (the "Acquisition")
by CCSC of CarnaudMetalbox S.A. ("CMB") and to fund costs and expenses of the
Acquisition, (b) to repurchase shares of capital stock of CCSC and (c) following
the Acquisition, for general corporate purposes.

          Chemical Bank ("Chemical") is pleased to advise you of its commitment
to provide a portion of the Facility equal to the FF 1,750,000,000,on the terms
and subject to the conditions set forth or referred to herein and in the Summary
of Terms and Conditions attached hereto as Exhibit A (the "Term Sheet").  You
hereby engage Chemical, and Chemical hereby agrees, to act as exclusive
administrative agent for the Facility and to perform all functions and exercise
all authority (including, without limitation, negotiating definitive credit
documentation) customarily performed and exercised by it in such capacities.
You hereby engage Chemical Securities Inc. ("CSI"), and CSI hereby agrees, to
act as arranger for and to manage the

 
                                                                               2

syndication of the Facility on the terms set forth herein.  Societe Generale and
Credit Suisse also will be named as arrangers and documentation agents for the
Facility, and certain banks, to be agreed by Chemical and CCSC, will be named as
senior lead managers for the Facility.  However, such arrangers, documentation
agents and senior lead managers will not perform any functions or have any
authority in such capacities.

          You agree to assist CSI in achieving a timely syndication of the
Facility that is satisfactory to Chemical and CSI.  This will be accomplished by
a variety of means, including direct contact during the syndication among the
senior officers, representatives and advisors of CCSC and its affiliates, on the
one hand, and the proposed Lenders, on the other hand.

          You agree promptly to provide, and to cause your advisors to provide,
and to use your best efforts to cause CMB and its advisors to provide, CSI upon
request with all information reasonably deemed necessary by it to complete
successfully the arrangement of the Facility (the "Information"), including your
periodic reports filed with the Securities and Exchange Commission, which shall
be complete and correct in all material respects and not contain any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements contained therein not materially misleading in light of
the circumstances under which such statements are made.

          As consideration for Chemical's commitment hereunder and for CSI's
agreement to arrange and syndicate the Facility, you agree to pay the fees set
forth in the Term Sheet and in the fee letter dated the date hereof and
delivered herewith (the "Fee Letter").

          Chemical's commitment hereunder is subject to (a) there not occurring
any material adverse change in the business, operations, condition (financial or
otherwise) or prospects of CCSC and its subsidiaries taken as a whole as shown
in the Information reviewed by Chemical prior to the date hereof, (b)
commitments being obtained for the balance of the Facility not committed for by
Chemical (subject to CCSC's right to reduce the amount of the Facility, it being
understood that, if the amount of the Facility is reduced below FF
12,330,000,000, then Chemical's commitment will be reduced ratably to the extent
of any reduction below that

 
                                                                               3

amount), (c) Chemical's satisfaction with the structure, terms and conditions of
the Acquisition and the documentation therefor (it being understood that
Chemical is satisfied with those matters communicated to it prior to the date
hereof), and (d) the negotiation, execution and delivery of definitive
documentation with respect to the Facility satisfactory to Chemical and its
counsel (which documentation will, to the extent consistent with the Term Sheet,
substantially incorporate the representations and warranties, covenants,
conditions and events of default contained in the Revolving Credit and
Competitive Advance Facility Agreement dated as of February 10, 1995, as
amended, among CCSC, certain subsidiaries of CCSC, the lenders referred to
therein and Chemical, as agent).  To the extent not covered by or made clear
under the provisions hereof and of the Term Sheet, the terms and conditions of
Chemical's commitment hereunder and of the Facility are subject to the mutual
agreement of Chemical and CCSC.

          By executing this letter agreement, you agree (a) to indemnify and
hold harmless CSI, Chemical and the other financial institutions which become
parties to the definitive credit documentation (together with Chemical, the
"Lenders") and their respective officers, directors, employees, affiliates,
agents and controlling persons from and against any and all losses, claims,
damages and liabilities (collectively, "Losses") to which any such person may
become subject arising out of or in connection with this Commitment Letter, the
Fee Letter, the Facility or any claim, litigation, investigation or proceeding
relating to any of the foregoing, regardless of whether any of such indemnified
parties is a party thereto, and to reimburse each of such indemnified parties
upon demand for any reasonable legal or other expenses incurred in connection
with investigating or defending any of the foregoing; provided that the
                                                      --------         
foregoing indemnity will not, as to any indemnified party, apply to Losses or
related expenses to the extent they arise from the wilful misconduct or gross
negligence of such indemnified party (or from the negligence of such indemnified
party if such Losses or related expenses result from an action brought against
such indemnified party by CCSC or by a stockholder or creditor of such
indemnified party); and (b) to reimburse CSI and Chemical from time to time for
all reasonable out-of-pocket expenses (including travel expenses and fees and
disbursements of counsel) incurred in connection with the Facility or the
transactions contemplated hereby, it being understood that the Company will
refer to its own internal expense reimbursement

 
                                                                               4
policies in determining reasonableness of expenses incurred and that
international travel must be approved by CCSC.  Chemical will consult with you
from time to time at your request as to the nature and amount of the expenses
for which it intends to seek reimbursement pursuant to clause (b) of the
preceding sentence.  The provisions contained in this paragraph shall remain in
full force and effect regardless of whether definitive financing documentation
shall be executed and delivered and notwithstanding the termination of this
Commitment Letter or the commitment hereunder.

          You agree that this Commitment Letter (including the Term Sheet) and
the Fee Letter are for your confidential use only and will not without the prior
agreement of CSI and Chemical be disclosed by you to any person other than your
accountants, attorneys and other advisors on a confidential basis; provided that
                                                                   --------     
following your execution hereof (i) you may disclose this Commitment Letter and
the Term Sheet (but not the Fee Letter) to CMB and their accountants, attorneys
and other advisors on a confidential basis; (ii) you may file a copy of this
Commitment Letter and the Term Sheet (but not the Fee Letter) in any public
record in which it is or may be required by law in your good faith judgment to
be filed; and (iii) you may make such other disclosures of the terms and
conditions hereof as you are or may be required by law, in the opinion of your
counsel, to make.

          If the foregoing correctly sets forth our agreement, please indicate
your acceptance of the terms hereof and of the Term Sheet by signing in the
appropriate spaces below and in the Fee Letter and returning to us the enclosed
duplicate originals of this Commitment Letter and the Fee Letter on or before
the close of business on August 25, 1995.  Chemical's commitment will expire in
the event that definitive documentation shall not have been executed by March
31, 1996, unless Chemical shall agree to an extension.  CCSC may terminate
Chemical's commitment at any time.

          This Commitment Letter shall not be assignable by you without the
prior written consent of CSI and Chemical, and may not be amended or waived
except by an instrument in writing signed by you, CSI and Chemical.  This
Commitment Letter may be executed in any number of counterparts, each of which
shall be an original and all of which, when taken together, shall constitute one
agreement.  This Commitment

 
                                                                               5

Letter shall be governed by, and construed in accordance with, the laws of the
State of New York.

          CSI and Chemical are pleased to have been given the opportunity to
arrange and serve as agent for this financing.

              Amendment to Commitment Letter
              ------------------------------

Dear Sirs:

          We refer to our commitment letter (the "Commitment Letter") to you,
dated August 25, 1995 and agreed and accepted by you as of such date, with
respect to a multi-currency credit facility (the "Facility") in the amount of
French Francs 13,700,000,000 (or its equivalent in other applicable currencies).
All capitalized terms used in this letter not defined herein shall have the
meanings assigned to such terms in the Commitment Letter.

          You have requested that we amend the Commitment Letter to reflect
certain changes in the terms of the Facility that have been agreed among us
since the date of the Commitment Letter.

          This letter shall serve to amend the Commitment Letter as described
below and, upon its execution by both of us, shall become a part thereof.

          The paragraph under the caption "Facility Fee" in ANNEX I to the Term
Sheet attached to the Commitment Letter is hereby amended to read as follows:

          A Facility Fee equal to the "Applicable Facility Fee Percentage" per
          annum will accrue and be payable by CCSC to the Lenders on the
          aggregate amount of the commitments under the Facility (and, on and
          after the Commitment Termination Date, on the aggregate principal
          amount of Term Loans outstanding), commencing on the Closing Date and
          payable in arrears at the end of each quarter and upon any termination
          of the commitments or repayment of Term Loans.  Facility Fees will be

 
                                                                               2

          payable in French Francs.  The "Applicable Facility Fee Percentage"
          shall be based on the ratings assigned to CCSC's senior unsecured debt
          by Standard & Poor's ("S&P") and Moody's Investors Service, Inc.
          ("Moody's") and shall equal (x) .0500% if CCSC's rating from S&P is A
          or better or from Moody's is A2 or better, (y) .0700% if CCSC's rating
          from S&P is A- to BBB or from Moody's is A3 to Baa2 or (z) .1250% if
          CCSC's rating from S&P is BBB- or below or from Moody's is Baa3 or
          below; provided that if the ratings established by S&P and Moody's
          shall fall into different categories, the Applicable Facility Fee
          Percentage shall be based on the higher of the two ratings.

          The first paragraph under the caption "Interest Rates" in ANNEX I to
the Term Sheet attached to the Commitment Letter is hereby amended to read as
follows:

          The interest rate applicable to LIBOR/PIBOR loans under the Facility
          will be equal to (a) LIBOR/PIBOR plus (b) the "Applicable Percentage"
          plus (c) 0.05% per annum on the earlier of (i) the date six months
          after the initial borrowing under the Facility and (ii) the date 210
          days after the Closing Date.  The "Applicable Percentage" shall be
          based on the ratings assigned to CCSC's senior unsecured debt by S&P
          and Moody's and shall equal (x) .1000% if CCSC's rating from S&P is A
          or better or from Moody's is A2 or better, (y) .1250% if CCSC's rating
          from S&P is A- to BBB or from Moody's is A3 to Baa2, or (z) .1750% if
          CCSC's rating from S&P is BBB- or below or from Moody's is Baa3 or
          below; provided that if the ratings established by S&P and Moody's
          shall fall into different categories, the Applicable Percentage shall
          be based on the higher of the two ratings.

          If the foregoing correctly sets out our agreement, please indicate
your acceptance of the terms hereof by signing the appropriate spaces below and
returning to us the enclosed duplicate originals of this letter.

          This letter may be executed in any number of counterparts, each of
which shall be an original and all of which, when taken together shall
constitute an agreement.

 
                                                                               3

This letter shall be governed by, and construed in accordance with, the laws of
the State of New York.
