its 9% Senior Subordinated Debentures due 2009 (the "Securities") to be issued
pursuant to the provisions of an Indenture (the "Indenture") to be dated as of
the Closing Date (as defined below) between the Company and The First National
Bank of Chicago, as Trustee (the "Trustee"). The Securities will be offered
without being registered under the Securities Act of 1933, as amended (the

description of the terms of the Securities, the terms of the offering and a
description of the Company and its business. As used herein, the term
"Memorandum" shall include in each case the documents incorporated by reference
therein. The terms "supplement", "amendment" and "amend" as used herein shall

Memorandum or Final Memorandum that are filed subsequent to the date of such
Memorandum with the Securities and Exchange Commission (the "Commission")

Act").

                  (h) Neither the Company nor any of its subsidiaries has
         sustained since the date of the latest audited financial statements
         included or incorporated by reference 

 
                                       4

         in each Memorandum any material loss or interference with its business
         from fire, explosion, flood or other calamity, whether or not covered
         by insurance, or from any labor dispute or court or governmental
         action, order or decree, otherwise than as set forth or contemplated in
         each Memorandum; and, since the respective dates as of which
         information is given in each Memorandum, there has not been any change
         in the capital stock or long-term debt of the Company or any of its
         subsidiaries or any material adverse change, or any development
         involving a prospective material adverse change, in or affecting the
         business, management, financial position, stockholders' equity
         (deficiency) or results of operations of the Company and its
         subsidiaries, otherwise than as set forth or contemplated in each
         Memorandum.

                  (i) Neither the Company nor any affiliate (as defined in Rule
         501(b) of Regulation D under the Securities Act, an "Affiliate") of the
         Company has, to the knowledge of the Company, directly, or through any
         agent, (i) sold, offered for sale, solicited offers to buy or otherwise
         negotiated in respect of, any security (as defined in the Securities
         Act) which is or will be integrated with the sale of the Securities in
         a manner that would require the registration under the Securities Act
         of the Securities or (ii) engaged in any form of general solicitation
         or general advertising in connection with the offering of the
         Securities (as those terms are used in Regulation D under the
         Securities Act) or in any manner involving a public offering within the
         meaning of Section 4(2) of the Securities Act.

                  (j) The Company is not and, after giving effect to the
         offering and sale of the Securities, will not be an "investment
         company" or an entity "controlled" by an "investment company", as such
         terms are defined in the Investment Company Act of 1940, as amended
         (the "Investment Company Act"), assuming The Morgan Stanley Leveraged
         Equity Fund II, L.P. ("MSLEF") is not an "investment company" and is
         not "controlled" by an "investment company".

                  (k) Assuming the accuracy of the representations and
         warranties of the Placement Agent in Section 6 hereof, it is not
         necessary in connection with the offer, sale and delivery of the
         Securities to the Placement Agent in the manner contemplated by this
         Agreement to register the Securities under the Securities Act or to
         qualify the Indenture under the Trust Indenture Act of 1939, as
         amended.

                  (l) Except as described in each Memorandum, the Company and
         its subsidiaries (A) are in compliance with any and all applicable
         foreign, federal, state and local laws and regulations relating to the
         protection of human health and safety, the environment or hazardous or
         toxic substances or wastes, pollutants or contaminants ("Environmental
         Laws"), (B) have received all permits, licenses or other approvals
         required of them under applicable Environmental Laws to conduct their
         respective businesses and (C) are in compliance with all terms and
         conditions 

 
                                       5

         of any such permit, license or approval, except where such
         noncompliance with Environmental Laws, failure to receive required
         permits, licenses or other approvals or failure to comply with the
         terms and conditions of such permits, licenses or approvals would not,
         singly or in the aggregate, have a material adverse effect on the
         Company and its subsidiaries, taken as a whole.

                  (m) In the ordinary course of its business, the Company
         conducts a periodic review of the effect of Environmental Laws on the
         business, operations and properties of the Company and its
         subsidiaries, in the course of which it identifies and evaluates
         associated costs and liabilities (including, without limitation, any
         material capital or operating expenditures required for clean-up,
         closure of properties or compliance with Environmental Laws or any
         material permit, license or approval, any related constraints on
         operating activities material to the Company and its subsidiaries, and
         any potential material liabilities to third parties). On the basis of
         such review, the Company has reasonably concluded that such associated
         costs and liabilities would not, singly or in the aggregate, have a
         material adverse effect on the Company and its subsidiaries, taken as a
         whole.

                  (n) None of the Company, its Affiliates or any person acting
         on its or their behalf (other than (i) the Placement Agent, (ii) MSLEF,
         (iii) any entity which controls MSLEF, (iv) any entity under common
         control with any such entity and (v) any subsidiary of any such entity
         other than any subsidiary of MSLEF (the parties identified in clauses
         (i) through (v) are the "Excluded Parties")) has engaged in any
         directed selling efforts (as that term is defined in Regulation S under
         the Securities Act ("Regulation S")) with respect to the Securities,
         and the Company and its Affiliates and any person acting on its or
         their behalf (other than the Excluded Parties) has complied with the
         offering restrictions requirement of Regulation S. To the knowledge of
         the Company, none of the Excluded Parties (other than the Placement
         Agent) has engaged in any directed selling efforts (as that term is
         defined in Regulation S) with respect to the Securities, and, to the
         knowledge of the Company, the Excluded Parties (other than the
         Placement Agent) have complied with the offering restrictions
         requirement of Regulation S.

                  (o) The Company and its subsidiaries have good and marketable
         title in fee simple to all real property and good and marketable title
         to all personal property owned by them, in each case free and clear of
         all liens, encumbrances and defects except such as are described in
         each Memorandum or such as do not materially affect the value of such
         property and do not interfere with the use made and proposed to be made
         of such property by the Company and its subsidiaries; and any real
         property and buildings held under lease by the Company and its
         subsidiaries are held by them under valid, subsisting and enforceable
         leases with such exceptions as are not material and do not interfere
         with the use made and proposed to be made of such property and

 
                                       6

         buildings by the Company and its subsidiaries, taken as a whole.

                  (p) Each of the Company and its subsidiaries has all necessary
         consents, authorizations, approval, orders, certificates and permits of
         and from, and has made all declarations and filings with, all federal,
         state, local and other governmental authorities, all self-regulatory
         organizations and all courts and other tribunals, to own, lease,
         license and use its properties and assets and to conduct its business
         in the manner described in each Memorandum, except to the extent where
         the failure to obtain any such consent, authorization, approval, order,
         certificate or permit or make any such declaration or filing would not
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole;

                  (q) Neither the Company nor any of its subsidiaries is in
         violation of its Certificate of Incorporation or By-laws or in default
         in the performance or observance of any obligation, agreement, covenant
         or condition contained in any indenture, mortgage, deed of trust, loan
         agreement, lease or other agreement or instrument to which it is a
         party or by which it or any of its properties or assets may be bound,
         except for such defaults as do not and will not have a material adverse
         effect on the Company and its subsidiaries, taken as a whole.

                  (r) The statements set forth in each Memorandum under the
         caption "Description of the Debentures", insofar as they purport to
         constitute a summary of the terms of the Securities and under the
         caption "Transfer Restrictions", insofar as they purport to describe
         the provisions of the laws and documents referred to therein, are
         accurate, complete and fair.

                  (s) Other than as set forth in each Memorandum, there are no
         legal or governmental proceedings pending to which the Company or any
         of its subsidiaries is a party or of which any property of the Company
         or any of its subsidiaries is the subject which, if determined
         adversely to the Company or any of its subsidiaries, would individually
         or in the aggregate have a material adverse effect on the current or
         future consolidated financial position, stockholders' equity or results
         of operations of the Company and its subsidiaries; and, to the best of
         the Company's knowledge, no such proceedings are threatened or
         contemplated by governmental authorities or threatened by others.

                  (t) Ernst & Young LLP, who have certified certain financial
         statements of the Company and its subsidiaries, are independent public
         accountants as required by the Securities Act and the rules and
         regulations of the Commission thereunder.

         the date on which all of the Securities shall have been sold by the
         Placement Agent, any event shall occur or condition exist as a result
         of which it is necessary in your judgment to amend or supplement the
         Final Memorandum in order to make the statements therein, in the light
         of the circumstances when such Memorandum is delivered to a purchaser,
         not misleading, or if, with the opinion of counsel to the Placement
         Agent it is necessary to amend or supplement such Memorandum to comply
         with applicable law, forthwith to prepare and furnish, at its own
         expense, to the Placement Agent, either amendments or supplements to
         such Memorandum so that the statements in such Memorandum as so amended
         or supplemented will not, in the light of the circumstances when such
         Memorandum is delivered to a purchaser, be misleading or so that such
         Memorandum, as so amended or supplemented, will comply with applicable
         law.

                  (d) To endeavor to qualify the Securities for offer and sale

         Section 5(d), including filing fees and the fees and disbursements of

         with the preparation of this Agreement, (viii) the fees and expenses,
         if any, incurred in connection with the admission of such Securities
         for trading in PORTAL or any other appropriate market system, (ix) the

         Placement Agent) will sell, offer for sale or solicit offers to buy or
         otherwise negotiate in respect of any security (as defined in the

         on its or their behalf (other than the Placement Agent) will engage in

                  (j) If requested by you, to use its best efforts to permit the

              6.   Offering of Securities; Restrictions on Transfer. (a) The
                   ------------------------------------------------
Placement Agent represents and warrants that it is a qualified institutional
buyer as defined in Rule 144A under the Securities Act (a "QIB"). The Placement
Agent agrees with the Company that (i) it will not solicit offers for, or offer
or sell, such Securities by any form of general solicitation or general
advertising (as those terms are used in Regulation D under the Securities Act)
or in any manner involving a public offering within the meaning of Section 4(2)
of the Securities Act and (ii) it will solicit offers for such Securities only
from, and will offer such Securities only to, persons that it reasonably
believes to be (A) in the case of offers inside the United States, (x) QIBs or
(y) other institutional accredited investors (as defined in Rule 501(a) (1),
(2), (3) or (7) under the Securities Act) ("institutional accredited investors")
that, prior to their purchase of the Securities, deliver to such Placement Agent
a letter containing the representations and agreements set forth in Annex A to
the Memorandum and (B) in the case of offers outside the United States, to
persons other than U.S. persons ("foreign purchasers", which term shall include
dealers or other professional fiduciaries in the United States acting on a
discretionary basis for foreign beneficial owners (other than an estate or
trust)) that, in each case, in purchasing such Securities are deemed to have
represented and agreed as provided in the Final Memorandum under the caption
"Transfer Restrictions."

              (b)  The Placement Agent represents, warrants, and agrees with
respect to offers and sales outside the United States that:

              (i)   it understands that no action has been or will be taken in
         any jurisdiction by the Company that would permit a public offering of
         the Securities, or possession or distribution of either Memorandum or
         any other offering or publicity material relating to the Securities, in
         any country or jurisdiction where action for that purpose is required;

              (ii)  the Placement Agent will comply with all applicable laws
         and regulations in each jurisdiction in which it acquires, offers,
         sells or delivers Securities or has in its possession or distributes
         either Memorandum or any such other material, in all cases at its own
         expense;

              (iii) the Securities have not been and will not be registered
         under the Securities Act and may not be offered or sold within the
         United States or to, or for the account or benefit of, U.S. persons
         except in accordance with Regulation S under the Securities Act or
         pursuant to an exemption from the registration requirements of the
         Securities Act;

              (iv)  the Placement Agent has offered the Securities and will
         offer and sell the Securities (A) as part of their distribution at any
         time and (B) otherwise until 40 days after the later of the
         commencement of the offering of the Securities and the

 
                                       12



         Closing Date, only in accordance with Rule 903 of Regulation S or
         another exemption from the registration requirements of the Securities
         Act. Accordingly, neither the Placement Agent, its Affiliates nor any
         persons acting on its or their behalf have engaged or will engage in
         any directed selling efforts (within the meaning of Regulation S) with
         respect to the Securities, and the Placement Agent, its Affiliates and
         any such persons have complied and will comply with the offering
         restrictions requirements of Regulation S;

              (v)   the Placement Agent has (A) not offered or sold and, prior
         to the date that is six months after the Closing Date, will not offer
         or sell any Securities to persons in the United Kingdom except to
         persons whose ordinary activities involve them in acquiring, holding,
         managing or disposing of investments (as principal or agent) for the
         purposes of their businesses or otherwise in circumstances which have
         not resulted and will not result in an offer to the public in the
         United Kingdom within the meaning of the Public Offers of Securities
         Regulations 1995; (B) complied and will comply with all applicable
         provisions of the Financial Services Act 1986 with respect to anything
         done by it in relation to the Securities in, from or otherwise
         involving the United Kingdom; and (C) only issued or passed on and will
         only issue or pass on in the United Kingdom any document received by it
         in connection with the issue of the Securities to a person who is of a
         kind described in Article 11(3) of the Financial Services Act 1986
         (Investment Advertisements) (Exemptions) Order 1996 or is a person to
         whom such document may otherwise lawfully be issued or passed on;

              (vi)  the Placement Agent understands that the Securities have
         not been and will not be registered under the Securities and Exchange
         Law of Japan, and represents that it has not offered or sold, and
         agrees that it will not offer or sell, any Securities, directly or
         indirectly, in Japan or to any resident of Japan except (A) pursuant to
         an exemption from the registration requirements of the Securities and
         Exchange Law of Japan and (B) in compliance with any other applicable
         requirements of Japanese law; and

              (vii) the Placement Agent agrees that, at or prior to confirmation
         of sales of the Securities, it will have sent to each distributor,
         dealer or person receiving a selling concession, fee or other
         remuneration that purchases any Securities from it during the
         restricted period a confirmation or notice to substantially the
         following effect:

              "The Securities covered hereby have not been registered
              under the U.S. Securities Act of 1933, as amended (the
              "Securities Act"), and may not be offered and sold within
              the United States or to, or for the account or benefit of,

 
                                       13


              U.S. persons (i) as part of their distribution at any time
              or (ii) otherwise until 40 days after the Closing Date,
              except in either case in accordance with Regulation S (or
              Rule 144A) under the Securities Act. Terms used above have
              the meaning given to them by Regulation S."

Terms used in this Section 6 have the meanings given to them by Regulation S.

              7.    Indemnification and Contribution. (a) The Company agrees to
                    --------------------------------
indemnify and hold harmless the Placement Agent, and each person, if any, who
controls such Placement Agent within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, or is under common control
with, or is controlled by, the Placement Agent, from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred by the Placement Agent or any such
controlling of affiliated person in connection with defending or investigating
any such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in either Memorandum (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact necessary to make the statements therein in light of the
circumstances under which they were made not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
relating to the Placement Agent furnished to the Company in writing by such
Placement Agent through you expressly for use therein.

              (b)   The Placement Agent agrees to indemnify and hold harmless
the Company, its directors, its officers and each person, if any, who controls,
or is under common control with or is controlled by the Company within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act to the same extent as the foregoing indemnity from the Company to the
Placement Agent, but only with reference to information relating to the
Placement Agent furnished to the Company in writing by the Placement Agent
through you expressly for use in either Memorandum or any amendments or
supplements thereto.

              (c)   In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to either paragraph (a) or (b) above, such
person (the "indemnified party") shall promptly notify the person against whom
such indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the reasonable fees and disbursements of such counsel

 
                                       14


related to such proceeding. In any such proceeding, any indemnified party shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that the indemnifying party shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all such indemnified parties and that all such reasonable fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by Morgan Stanley & Co. Incorporated in the case of parties
indemnified pursuant to paragraph (a) above and by the Company in the case of
parties indemnified pursuant to paragraph (b) above. The indemnifying party
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by the second
and third sentences of this paragraph, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

              (d)   To the extent the indemnification provided for in paragraph
(a) or (b) of this Section 7 is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company, on the one hand, and the Placement Agent, on
the other hand, from the offering of such Securities or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company on the one
hand and the Placement Agent on the other hand in connection with the statements
or omissions that resulted in such losses, claims, damages

 
                                       15

or liabilities, as well as any other relevant equitable considerations. The
relative benefits received by the Company on the one hand and the Placement
Agent on the other hand in connection with the offering of such Securities shall
be deemed to be in the same respective proportions as the net proceeds from the
offering of such Securities (before deducting expenses) received by the Company
and the total discounts and commissions received by the Placement Agent in
respect thereof bear to the aggregate offering price of such Securities. The
relative fault of the Company on the one hand and of the Placement Agent on the
other hand shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or by the Placement Agent and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

              (e)   The Company and the Placement Agent agree that it would not
be just or equitable if contribution pursuant to this Section 7 were determined
by pro rata allocation or by any other method of allocation that does not take
account of the equitable considerations referred to in paragraph (d) above. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in paragraph (d) above shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 7, the Placement Agent shall not be required to
contribute any amount in excess of the amount by which the total price at which
the Securities resold by it in the initial placement of such Securities were
offered to investors exceeds the amount of any damages that the Placement Agent
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

              (f)   The indemnity and contribution provisions contained in this
Section 7 and the representations and warranties of the Company contained in
this Agreement shall remain operative and in full force and effect regardless of
(i) any termination of this Agreement, (ii) any investigation made by or on
behalf of the Placement Agent or any person controlling the Placement Agent or
by or on behalf of the Company, its officers or directors or any person
controlling the Company and (iii) acceptance of and payment for any of the
Securities. The remedies provided for in this Section 7 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

              8.    Termination. This Agreement shall be subject to termination
                    -----------
by notice given by you to the Company, if (a) after the execution and delivery
of this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock

 
                                       16

Exchange, the American Stock Exchange, the National Association of Securities
Dealers, Inc., the Chicago Board of Options Exchange, the Chicago Mercantile
Exchange or the Chicago Board of Trade, (ii) trading of any securities of the
Company or of Silgan Holdings Inc. shall have been suspended on any exchange or
in any over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial markets or any calamity or crisis
that, in your judgment, is material and adverse and (b) in the case of any of
the events specified in clauses (a)(i) through (iv), such event singly or
together with any other such event makes it, in your judgment, impracticable to
market the Securities on the terms and in the manner contemplated in the Final
Memorandum.

              9.    Miscellaneous.  This Agreement may be signed in any number
                    -------------
of counterparts, each of which shall be an original, with the same effect as if
the signatures thereto and hereto were upon the same instrument.

              If this Agreement shall be terminated by the Placement Agent,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Placement Agent for all out-of-pocket
expenses (including the fees and disbursements of their counsel) reasonably
incurred by the Placement Agent in connection with this Agreement or the
offering contemplated hereunder.

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

              The headings of the sections of this Agreement have been inserted
for convenience of reference only and shall not be deemed a part of this
Agreement.
