Attention: Mr. Timothy W. Stonich
        Executive Vice President
        and Chief Financial Officer
 
Ladies and Gentlemen:
 
     The purpose of this letter is to confirm the engagement of Salomon Brothers
Inc ("Salomon") by U.S. Can Corporation (the "Company") on an exclusive basis to
render financial advisory and investment banking services to the Company in
connection with the possible acquisition (by merger, tender offer or otherwise)
by the Company (or a subsidiary of the Company) of Crown, Cork and Seal Company,
Inc.'s selected European Aerosol Can Businesses (the "Subject Company") or the
possible purchase by the Company (or a subsidiary of the Company) of all or a
significant portion of the assets, or of the equity securities, of the Subject
Company, in a transaction with Aggregate Consideration (as defined in Section 2
herein) greater than $20 million (an "Acquisition Transaction").
 
     Section 1. Services to be Rendered. Salomon will perform such of the
following financial advisory and investment banking services as the Company may
reasonably request:
 
          (a) Salomon will familiarize itself to the extent it deems appropriate
     and feasible with the business, operations, properties, financial condition
     and prospects of the Company and the Subject Company, it being understood
     that Salomon shall, in the course of such familiarization, rely entirely
     upon publicly available information and such other information as may be
     supplied by the Company or the Subject Company, without independent
     investigation;
 
          (b) Salomon will advise and assist the Company in considering the
     desirability of effecting an Acquisition Transaction, and, if the Company
     believes such a transaction to be desirable, in developing a general
     strategy for accomplishing an Acquisition Transaction, including advice
     with respect to the structuring of the terms, conditions and financing of
     any proposed Acquisition Transaction;
 
          (c) Salomon will advise and assist management of the Company in making
     presentations to the Board of Directors of the Company concerning a general
     acquisition strategy, the Subject Company and any proposed Acquisition
     Transaction;
 
          (d) Salomon will advise and assist the Company in the course of its
     negotiation of an Acquisition Transaction and, if requested by the Company,
     will participate directly in such negotiations;
 
          (e) If so requested by the Company, Salomon will render, in accordance
     with its customary practice, an opinion (the "Opinion") as to the fairness,
     from a financial point of view, to the Company of the consideration to be
     paid by the Company in an Acquisition Transaction, with the understanding
     that in rendering the Opinion Salomon will rely, without independent
     investigation, on information furnished to it by the Company (which
     information the Company hereby warrants shall be complete and accurate in
     all material respects, and not misleading in any material respect), the
     Subject Company or other relevant parties or publicly available and that
     the Opinion may be in such form as Salomon shall determine and Salomon may
     qualify the Opinion in such manner as Salomon believes appropriate. The
     Opinion shall not address the Company's underlying business decision to
     effect an Acquisition Transaction. Notwithstanding anything to the contrary
     elsewhere herein, the Company may reproduce the Opinion in full in any
     disclosure document or proxy statement relating to such Acquisition
     Transaction (the "Statement") that the Company must file under the
     Securities Exchange Act of 1934 and distribute to its shareholders. In such
     event, the Company may also include references to the Opinion and to
   2
 
     Salomon and its relationship with the Company (in each case in such form as
     Salomon shall approve) in the Statement;
 
          (f) Salomon will advise and assist the Company in connection with any
     interest rate, currency rate or other hedge program(s) of the Company
     relating to an Acquisition Transaction, including, if the Company so
     requests, assisting in the structuring of such program(s), the
     identification of acceptable counterparties (which may include Salomon or
     one of its affiliates) in connection therewith and the management of any
     related auctions;
 
          (g) Salomon will render such other financial advisory and investment
     banking services as may from time to time be agreed upon by Salomon and the
     Company.
 
     Section 2. Fees. The Company shall pay to Salomon for its services
     hereunder the following cash fees:
 
          (a) $50,000, payable promptly following the Company being invited to
     perform due diligence with respect to the Subject Company; plus
 
          (b) $25,000, payable upon submission by the Company of a proposal
     regarding an Acquisition Transaction; plus
 
          (c) an additional fee equal to a percentage of the Aggregate
     Consideration, determined according to the table on Appendix A reduced by
     5%, (less the amounts payable under the immediately preceding clauses (a)
     and (b)) such additional fee to be contingent upon the consummation of an
     Acquisition Transaction and payable at the closing thereof.
 
          For purposes hereof, the term Aggregate Consideration shall mean the
     total amount of cash and the fair market value (on the date of payment) of
     all other property paid or payable directly or indirectly by the Company in
     connection with an Acquisition Transaction or a transaction related thereto
     (including, without limitation, amounts paid by the Company, pursuant to
     covenants not to compete, employment contracts, employee benefit plans or
     other similar arrangements). Aggregate Consideration shall also include the
     value of any long-term liabilities of the Subject Company (including the
     principal amount of any indebtedness for borrowed money and any
     intercorporate debt) (x) repaid or retired in connection with or
     anticipation of an Acquisition Transaction or (y) existing on the Subject
     Company's balance sheet at the time of an Acquisition Transaction (if such
     Acquisition Transaction takes the form of a merger or a sale of stock) or
     assumed by the Company in connection with an Acquisition Transaction (if
     such Acquisition Transaction takes the form of a sale of assets). If an
     Acquisition Transaction takes the form of a sale of assets, the term
     Aggregate Consideration shall also include (i) the value of any current
     assets not sold, minus (ii) the value of any current liabilities not
     assumed by the Company.
 
     Section 3. Related Financial Transactions and Fees.
 
          (a) If, prior to an Acquisition Transaction or within one year
     following its consummation, the Company or any of its affiliates determines
     to sell (or cause the Subject Company or any of its affiliates to sell), in
     a public offering or a private placement, any debt securities (other than
     senior bank debt) and/or equity securities (such debt or equity securities
     being the "Securities") in connection with the financing of such
     Acquisition Transaction or refinancing of such Acquisition Transaction debt
     (including any issuance of Securities required to be made pursuant to a
     bridge loan agreement) or the refinancing of the Subject Company's existing
     debt, the Company, the Subject Company or its affiliate shall retain
     Salomon as lead underwriter (in the case of a public offering) or as lead
     placement agent (in the case of a private placement) of the Securities. Any
     such sale of Securities shall be pursuant to an underwriting agreement or
     placement agent agreement, as the case may be, containing customary
     representations, warranties, covenants, conditions and indemnities and
     providing for customary underwriting discounts or placement fees, the exact
     amounts to be mutually agreed upon.
 
          (b) If, prior to an Acquisition Transaction or within one year
     following its consummation, the Company determines to sell (or cause the
     Subject Company to sell) any subsidiary or division or other significant
     portion of the assets of the Subject Company, the Company shall afford
     Salomon a reasonable opportunity to compete with other parties on an equal
     basis to act as its exclusive financial advisor in
 
                                        2
   3
 
     connection with such proposed sale. Any such engagement shall be pursuant
     to an engagement letter containing customary provisions and terms and
     providing for customary fees, the exact amounts to be mutually agreed upon.
 
          (c) In connection with the hedge programs described in Section 1
     hereof, the Company agrees to afford Salomon a reasonable opportunity to
     compete with other parties on an equal basis in offering to the Company any
     interest rate, currency or other hedge products and not to enter into any
     exclusive or preferential agreements with such other parties with respect
     to such hedge products unless and until Salomon has been afforded such an
     opportunity. Any hedge products to be provided by Salomon to the Company
     shall be pursuant to separate written agreement(s) containing customary
     provisions and providing for customary fees, the exact amounts to be
     mutually agreed upon.
 
     Section 4. Expenses. In addition to any fees that may be payable to Salomon
hereunder and regardless of whether any Acquisition Transaction is proposed or
consummated, the Company hereby agrees, from time to time upon request, to
reimburse Salomon for all reasonable fees and disbursements of Salomon's counsel
(which counsel's fees shall not exceed $25,000 without the prior approval of the
Company) and all of Salomon's reasonable travel and other out-of-pocket expenses
incurred in connection with any actual or proposed Acquisition Transaction or
otherwise arising out of Salomon's engagement hereunder.
 
     Section 5. Indemnity. Salomon and the Company have entered into a separate
letter agreement, dated the date hereof, providing for the indemnification of
Salomon by the Company in connection with Salomon's engagement hereunder.
 
     Section 6. Termination of Engagement. Salomon's engagement hereunder may be
terminated by either the Company or Salomon at any time, with or without cause,
upon written advice to that effect to the other party; provided, however, that
Salomon will be entitled to its full fee under Section 2 hereof and to render
the services provided for in Sections 4(a), 4(b) and 4(c) hereof in the event
that at any time prior to the expiration of one year after such termination an
Acquisition Transaction is consummated; and provided, further, that the
provisions of this Section 6 and of Sections 4 and 7 hereof shall survive such
termination.
 
     Section 7. Miscellaneous.
 
          (a) THIS LETTER AGREEMENT AND THE RELATED INDEMNIFICATION AGREEMENT
     REFERRED TO ABOVE SHALL BE DEEMED MADE IN NEW YORK. SUCH AGREEMENTS SHALL
     BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO SUCH
     STATE'S RULES CONCERNING CONFLICTS OF LAWS. ANY RIGHT TO TRIAL BY JURY WITH
     RESPECT TO ANY CLAIM OR PROCEEDING RELATED TO OR ARISING OUT OF THIS
     ENGAGEMENT, OR ANY TRANSACTION OR CONDUCT IN CONNECTION HEREWITH, IS
     WAIVED.
 
          (b) The Company expressly acknowledges that all opinions and advice
     (written or oral) given by Salomon to the Company in connection with
     Salomon's engagement are intended solely for the benefit and use of the
     Company (including its management, directors and attorneys) in considering
     the transaction to which they relate and the Company agrees that no such
     opinion or advice shall be used for any other purpose or reproduced,
     disseminated, quoted or referred to at any time, in any manner or for any
     purpose, nor shall any public references to Salomon be made by the Company
     (or such persons), without the prior written consent of Salomon, which
     consent shall not be unreasonably withheld.
 
          (c) The Company expressly acknowledges that Salomon has been retained
     solely as an advisor to the Company, and not as an advisor to or agent of
     any other person, and that the Company's engagement of Salomon is not
     intended to confer rights upon any persons not a party hereto (including
     shareholders,
 
                                        3

     employees or creditors of the Company) as against Salomon, Salomon's
     affiliates or their respective directors, officers, agents and employees.
