Inc., a Delaware  corporation (the "Company"),  by providing an additional means
of attracting and retaining officers and key personnel. It is intended that this
purpose be achieved by  extending  to  designated  officers or  employees of the
Company an added  long-term  incentive  for high levels of  performance  and for
unusual  efforts  designed to improve the financial  performance of the Company,
through the grant of options to purchase  shares of common  stock of the Company
(as described  herein).  It is further  intended that pursuant to this Plan, the
Committee  may  grant  either  ISOs or  Nonstatutory  Options  (both as  defined
herein).

         Corporation  or  other  restructuring  of  the  Company  in  which  the

II.  ADMINISTRATION; PARTICIPATION.

         2.1      Administration.

                  This Plan shall be administered by the Committee,  none of the
members of which are  currently  eligible  to receive  Options and have not been
eligible  to receive  Options for at least  twelve  (12)  months  prior to their
selection  to the  Committee.  The action of the  Committee  with respect to the
administration  of this Plan shall be taken  pursuant to a majority  vote or the
written  consent  of a  majority  of its  members.  In the  event  action by the
Committee  is taken  by  written  consent  of its  members,  the  action  by the
Committee  shall be  deemed  to have  been  taken  at the  time the last  member
required for valid action by the Committee signs the consent.

                  Subject to the express  provisions of this Plan, the Committee
shall have the authority to construe and interpret  this Plan and any agreements
defining the rights and obligations of the Company and  participants  under this
Plan, to further  define the terms used in this Plan,  to  prescribe,  amend and
rescind rules and regulations  relating to the  administration  of this Plan, to
determine the duration and purposes of leaves of absence which may be granted to
participants without constituting a termination of their employment for purposes
of this Plan and to make all other determinations necessary or advisable for the
administration  of  this  Plan.  The  determinations  of  the  Committee  on the
foregoing matters shall be conclusive.

                  Subject to the express  provisions of this Plan, the Committee
shall select from the eligible class of employees of the Company or a Subsidiary
and make corresponding  recommendations to the Board of Directors concerning the
individuals  to whom Options  shall be granted and the terms and  provisions  of
such  Options  (which  need  not  be  identical)  including,  but  not by way of
limitation,  the time at which such Options shall be granted,  whether an Option
granted  hereunder  shall be intended to be treated as an ISO or a  Nonstatutory
Option, the number of shares subject to each Option and the Option Price and the
consideration  acceptable  in payment of the Option Price.  The Committee  shall
also determine, as to each individual to whom Options shall be granted effective
as of  June  30,  1989,  the  Carryover  Amount,  if  any,  applicable  to  such
individual.

                  No member of the  Committee  shall be liable  for any  action,
failure to act,  determination or interpretation made in good faith with respect



                                       -3-





to this  Plan  or any  transaction  hereunder.  The  Company  hereby  agrees  to
indemnify  each member of the  Committee  for all costs and expenses and, to the
extent  permitted by  applicable  law, any  liability  incurred by any member in
connection with defending against,  responding to, negotiating the settlement of
or  otherwise  dealing  with any  claim,  cause of action or dispute of any kind
arising in connection with the member's  actions in  administering  this Plan or
authorizing or denying authorization to any transaction hereunder.

                  The  Board  of  Directors,  at any  time  it so  desires,  may
increase or  decrease  the number of members of the  Committee,  may remove from
membership on the  Committee all or any portion of its members,  and may appoint
such  person or  persons  as it  desires  to fill any  vacancy  existing  on the
Committee, whether caused by removal, resignation or otherwise.

         2.2      Participation.

                  Only  officers  or  key  employees  of  the  Company,  or of a
Subsidiary,  whose responsibility levels indicate their ability to substantially
contribute  to the  Company's  growth  and  development  shall be  eligible  for
selection by the Committee to participate in this Plan; provided,  however, that
members of the Committee shall not, while members of this Committee, be eligible
to  receive  Options  under  this  Plan.  In  addition,  members of the Board of
Directors who are not officers or employees of the Company or of any  Subsidiary
shall not be eligible to receive  Options under this Plan. An individual who has
been granted an Option may, if otherwise eligible, be granted additional Options
if the Committee so determines.

                  Notwithstanding  anything  herein to the contrary,  during the
initial term of the Amended and Restated  Management Services Agreement dated as
of February 12, 1997 by and between S&H, Inc. and the Company (i.e.,  until June
30, 1999,  unless such initial  term is  terminated  for any reason prior to the
expiration thereof), Options may be granted under this Plan to either of the S&H
Stockholders  if, and only if, any such  grant of Options is  approved  by (i) a
majority of the members of the Committee (which majority must include a majority
of the members of the Committee  excluding any of the S&H Stockholders  that are
members of the  Committee)  and (ii) a majority  of the  members of the Board of
Directors (which majority must include a majority of the members of the Board of
Directors excluding any of the S&H Stockholders that are members of the Board of
Directors).

         2.3      Stock Subject to the Plan.

                  Subject to Section 4.1 hereof,  the stock to be offered  under
this Plan shall be shares of  authorized  but  unissued  Common  Stock or Common
Stock held in  treasury.  The  aggregate  amount of Common Stock to be delivered
upon exercise of all Options  granted under the Plan shall not exceed the sum of
(i) 124,000 shares plus (ii) such number of shares issuable upon exercise of all


                                       -4-





Options  that will be  outstanding  upon and in the event of the  conversion  to
Options of  options  under and in  accordance  with  stock  option  plans of all
Subsidiaries,  with such sum being subject to adjustment as set forth in Section
4.1 of this Plan.  Such amount of Common  Stock is hereby  reserved for issuance
under this Plan. If any Option shall expire or terminate for any reason  without
having been fully exercised,  the unexercised shares subject thereto shall again
be available for the purposes of this Plan.

         2.4      Stock Option Agreements.

                  Each Option  granted  pursuant to this Plan shall be evidenced
by an Incentive Stock Option Agreement or a Nonstatutory  Stock Option Agreement
(any of which are at times  herein  referred  to as an  "Option  Agreement"  or,
collectively,  as  "Option  Agreements"),  which  shall  set forth the terms and
conditions  of the option and specify  whether  such option is intended to be an
ISO or a Nonstatutory Stock Option.


III.  OPTIONS.

         3.1      Option Price.

                  Except as otherwise  provided  herein,  the purchase price per
share of the Common Stock  covered by each Option (the "Option  Price") shall be
determined  by the  Committee;  provided,  however,  the Option Price for an ISO
shall not be less than the Fair Market Value of the Common Stock  covered by the
Option at the time of grant.  The Option Price of any share  purchased  shall be
paid in full at the time of each purchase in cash, by check,  or,  provided that
all necessary regulatory approvals have been received, and provided further that
the Option  Agreement  provides for such  exercise,  the person  exercising  the
Option  may  deliver  in  payment  of  all or a  portion  of  the  Option  Price
certificates  for other shares of Common Stock which shall be valued at the Fair
Market Value of such Common Stock as of the date of exercise of the Option.

         3.2      Option Period.

                  Except as otherwise provided herein or as otherwise determined
by the  Committee,  each Option and all rights or obligations  thereunder  shall
expire on such date as shall be provided in the Option Agreement,  but not later
than the tenth anniversary  (fifth  anniversary in the case of an ISO granted to
an  employee  who owns or is  deemed  to own at the time of grant  more than ten
percent (10%) of the total combined  voting power of all classes of stock of the
Company or a Subsidiary)  of the date on which the Option is granted,  and shall
be subject to earlier termination as hereinafter provided.



                                       -5-





         3.3      Exercise of Options.

                  Each Option shall become  exercisable  and the total number of
shares  subject  thereto shall be  purchasable  no sooner than one year from the
date of the grant of the Option, and only in such  installments,  which need not
be equal, as specified in the Option Agreement. If the holder of an Option shall
not in any given installment  period purchase all of the shares which the holder
is entitled  to  purchase in such  installment  period,  the  holder's  right to
purchase any shares not so purchased in such  installment  period shall continue
until  the  expiration  or  earlier  termination  of the  holder's  Option.  The
Committee  may,  at any time  after  grant of the  Option and from time to time,
increase  the number of shares  purchasable  in any  installment  so long as the
total  number of shares  subject  to the Option is not  increased.  No Option or
installment  thereof shall be exercisable except in respect of whole shares, and
fractional  share  interests  shall  be  disregarded  except  that  they  may be
accumulated in accordance with the second sentence of this Section 3.3. No fewer
than ten (10) shares may be purchased at one time unless the number purchased is
the total  number at the time  available  for  purchase  under the  Option.  The
Committee may impose such  conditions or  limitations,  as shall be specified in
the  applicable  Option  Agreement,  on the sale or  transfer  of  Common  Stock
acquired upon exercise of an Option as it may deem necessary or desirable.

         3.4      Nontransferability of Options.

                  An Option  granted  under this Plan  shall,  by its terms,  be
nontransferable  by the holder  other  than by will or the laws of  descent  and
distribution,  and shall be exercised  during the holder's  lifetime only by the
holder or a duly appointed guardian or personal representative.

         3.5      Termination of Employment.

                  (a) If an Option holder ceases to be an officer of or employed
by the  Company  or a  Subsidiary  because  of  the  Option  holder's  voluntary
termination of employment, the Option will be exercisable only until the date of
resignation from office or termination of employment, to the extent, and only to
the extent, installments had become exercisable as of the date of termination of
employment or resignation from office.

                  (b) If an Option holder ceases to be an officer of or employed
by either  the  Company or a  Subsidiary  for any  reason  other than  voluntary
termination  specified in Section  3.5(a),  the Option  holder shall have ninety
(90) days, or such other period provided in the Option Agreement,  from the date
of termination of employment to exercise his or her Option,  to the extent,  and
only to the extent,  installments  had become  exercisable  prior to the date of
termination of employment or removal or resignation from office.


                                       -6-






         3.6      Permanent Disability of Employee.

                  If an Option  holder is no longer an officer of or employed by
either the Company or a  Subsidiary,  as a result of  permanent  disability  (as
defined below), the holder shall have twelve (12) months, or such shorter period
as is  provided  in the  Option  Agreement,  from  the  date of  termination  of
employment to exercise his or her Option.  The Option shall expire at the end of
such  12-month  period  (or such  shorter  period as is  provided  in the Option
Agreement  or as  provided  pursuant  to Section  3.2  hereof) to the extent not
exercised within that period. As used herein,  "permanent disability" shall mean
the  inability  of an Option  holder by reason of  illness  or injury to perform
substantially  all of his or her  duties  as an  employee  of the  Company  or a
Subsidiary during any continued period of one hundred eighty (180) days.

         3.7      Death of Employee.

                  If an Option  holder  dies while an officer of or  employed by
the Company or a Subsidiary,  or during the periods  described in Section 3.5(b)
or 3.6 hereof,  the holder's Option shall be exercisable during the twelve-month
period, or such shorter period as is provided in the Option Agreement, following
the holder's death, by the executor of the holder's will, the  administrator  of
the holder's estate, or as otherwise provided in the Option Agreement,  (and not
otherwise, regardless of any community property or other interest therein of the
spouse of the holder or such spouse's  successor in interest),  provided that in
no event shall the Option be exercised  after the period provided for in Section
3.2 hereof.  Unless  sooner  terminated  pursuant to the Plan,  the Option shall
expire at the end of such  twelve-month  period  (or such  shorter  period as is
provided  in the Option  Agreement  or as is  provided  pursuant  to Section 3.2
hereof) to the extent not  exercised  within that period.  In the event that the
holder's spouse shall have acquired a community property interest in the Option,
the holder, the executor of the holder's will, the administrator of the holder's
estate,  or such other Person as is otherwise  provided in the Option Agreement,
may exercise  the option on behalf of the spouse of the holder or such  spouse's
successor in interest.

         3.8      Limitation on Grant of ISOs.

                  The aggregate Fair Market Value  (determined as of the date or
dates the ISO or ISOs are granted) of the Common Stock with respect to which the
ISO or ISOs  granted to an employee are  exercisable  for the first time by such
employee  during any one calendar year (under this Plan and all other  incentive
stock option plans of the Company or any Subsidiary) shall not exceed $100,000.



                                       -7-





         3.9      Option Shall be Designated an ISO or Nonstatutory  Option.

                  The Option Agreement for each option grant shall state whether
the Options granted thereby are intended to be ISOs or Nonstatutory Options.


IV.  OTHER PROVISIONS.

         4.1      Adjustments Upon Changes in Capitalization and Ownership.

                  Subject to Section  4.2 below,  if the  outstanding  shares of
Common Stock are  increased,  decreased  or changed  into,  or exchanged  for, a
different  number or kind of  shares  or  securities  of the  Company  through a
reorganization  or  merger  in  which  the  Company  is  the  surviving  entity,
combination,  recapitalization,  reclassification, stock split-up, reverse stock
split,  stock dividend,  stock  consolidation  or otherwise,  an appropriate and
proportionate  adjustment  shall be made in the  number  and kind of shares  for
which  Options  may be  granted  as set forth in  Section  2.3 hereof and in the
Carryover  Amount.  A  corresponding  adjustment  changing the number or kind of
shares and the  exercise  price per share  allocated to  unexercised  Options or
portions  thereof,  which shall have been granted prior to any such change,  and
the  Carryover  Amount,  shall also be made.  Subject,  in the case of ISOs,  to
Section 424 of the Code,  any such  adjustment,  however,  shall be made without
change in the total price  applicable to the  unexercised  portion of the Option
but with a corresponding adjustment in the price for each share.

                  Upon  the  dissolution  or  liquidation  of the  Company,  or,
subject to Section 4.2 below, upon a reorganization,  merger or consolidation of
the Company  with one or more  corporations  as a result of which the Company is
not the  surviving  corporation,  in which  such  surviving  corporation  (or an
affiliate), if applicable,  does not assume all obligations of the Company under
this Plan and  substitute  for the  unexercised  Options  granted under the Plan
options to purchase  securities  of such  surviving  corporation  having a value
substantially  equivalent  to or greater  than the Common  Stock  issuable  upon
exercise of such Options and on terms  substantially  the same as or better than
those granted under the Plan, such Options shall become immediately  exercisable
upon the  occurrence  of such an  event,  but in no event  may such  Options  be
exercised  after  the  exercise  period  specified  in  each  individual  Option
Agreement.

                  Adjustments  under  this  Section  4.1  shall  be  made by the
Committee,  whose  determination as to what  adjustments  shall be made, and the
extent thereof, shall be final, binding and conclusive.  No fractional shares of
Common Stock shall be issued under this Plan on account of any such  adjustment.
If for any reason any person becomes entitled to any interest in a fractional


                                       -8-





share, a cash payment shall be made of an equivalent value of such interest.

         4.2      Change of Control.

                  In the  event of a Change  of  Control  other  than a  Pooling
Transaction  (as  hereinafter  defined)  during the term of one or more Options,
such Options shall,  subject to Section 4.1 above,  remain outstanding and shall
become  exercisable  by the holder  thereof upon the terms and conditions of the
Plan and the Option  Agreement  between such holder and the  Company;  provided,
however, the Committee may, in its discretion, take one or more of the following
actions  in  connection   with  a  Change  of  Control  (other  than  a  Pooling
Transaction):

                           (a)  The  Committee  may  declare  that  any  or  all
Options  shall  terminate  as of a date to be  fixed  by the  Committee  and may
require that the respective  holders thereof surrender all or a portion of their
unexercised Options for cancellation by the Company prior to such date and, upon
such  surrender,  such holders shall  receive (i) the cash,  securities or other
consideration   they  would  have  received  had  they  exercised  such  Options
immediately  prior to such  Change of  Control  and had they  disposed  of their
shares of Common  Stock  issuable  upon such  exercise in  connection  with such
Change of Control (subject to required deductions and withholdings),  minus (ii)
an amount of cash or fair market value of securities or other such consideration
equal to the Option Price for such Options surrendered; or

                           (b)  The  Committee   may  declare  that,   upon  the
exercise  by a  holder  of any or all  Options  after a  Change  of  Control  in
accordance  with the  provisions  of the Plan,  such holder shall be entitled to
receive  only the cash,  securities  or other  consideration  he would have been
entitled to receive had he  exercised  such  Options  immediately  prior to such
Change of Control  and had he disposed of the Common  Stock  issuable  upon such
exercise in connection with such Change of Control; or

                           (c)  The  Committee  may  declare  that  any  or  all
Options  shall  terminate as of a date to be fixed by the Committee and give the
holders thereof the right to exercise their Options prior to such date as to all
or any part thereof; or

                           (d)  The   Committee   may   permit   the   successor
corporation  to assume  the  obligations  of the  Company  under the Plan and to
substitute  for the  unexercised  Options  granted  under  the Plan  options  to
purchase  securities of such successor  corporation having a value substantially
equivalent  to or greater than the Common Stock  issuable  upon exercise of such
Options  and on terms  substantially  the same as or better  than those  granted
under the Plan,  all as determined by the Committee,  whereupon all  outstanding
Options and all future Options granted under the Plan shall  thenceforth  become
options to purchase such securities of such successor corporation on such terms.


                                       -9-






                  Notwithstanding  anything herein or in any Option Agreement to
the contrary,  if,  during the term of one or more Options,  there shall occur a
Change of Control which is intended to qualify as a "pooling of  interests"  for
accounting and financial reporting purposes (a "Pooling Transaction"),  it shall
be a condition to the  effectiveness of such Change of Control  transaction that
the acquiror  agree to assume the  obligations of the Company under the Plan and
to provide for the substitution of options to purchase securities equivalent to,
and with terms the same as, those granted  under the Plan,  all as determined by
the Committee.

         4.3      Continuation of Employment.

                  Nothing  contained  in this  Plan  (or in any  Option  granted
pursuant to this Plan) or in any Option Agreement shall confer upon any employee
any right to continue in the employ of the Company or a Subsidiary or constitute
any contract or agreement of  employment  or interfere in any way with the right
of the Company or a Subsidiary to reduce any person's compensation from the rate
in  existence at the time of the granting of an Option or Right or to change any
person's  position or duties or to demote or terminate such person's  employment
with or without cause,  but nothing  contained herein or in any Option Agreement
shall effect any contractual rights of an employee obtained otherwise than under
this Plan.

         4.4      Government Regulations.

                  This Plan and the  grant  and  exercise  of  Options  shall be
subject to all applicable rules and regulations of governmental authorities.

         4.5      Withholding.

                  The Company  may  require,  as a  condition  to (1) issuing or
delivering  to the holder of an Option  shares or  certificates  evidencing  the
shares  upon  exercise  of the Option or (2)  allowing  the  transfer  of shares
subsequent to their  issuance to the holder of an Option,  that the holder of an
Option or other person  exercising the Option pay any sums that federal,  state,
or local tax law  requires  to be  withheld  with  respect to such  exercise  or
transfer.  Neither the Company nor any  Subsidiary  shall be obligated to advise
any  holder of an Option of the  existence  of the tax or the  amount  which the
Company will be so required to withhold.

         4.6      Amendment, Termination, and Reissuance.

                  (a) The Board of Directors may at any time  suspend,  amend or
terminate this Plan (or any part thereof) and, with the consent of the holder of
an  Option,  may make such  modifications  of the terms and  conditions  of such
holder's Option as it shall deem advisable.  No Option may be granted during any



                                      -10-





suspension of this Plan or after such termination. The amendment,  suspension or
termination  of this Plan shall  not,  without  the  consent of the holder of an
Option,  adversely  alter or impair any rights or  obligations  under any Option
theretofore granted under this Plan. The Committee shall have the power and may,
with the consent of the holder of any  Option,  cancel any  existing  Option and
reissue Options to the holder of those canceled Options,  having a new and lower
Option Price, but otherwise bearing  substantially similar terms to the canceled
Options.

                  (b) In  addition  to the Board of  Directors'  approval of any
amendment,  if the  amendment  would  (i)  increase  the  benefits  accruing  to
participants  in this Plan,  (ii) increase the aggregate  number of shares which
may be issued under this Plan, or (iii) modify the  requirements  of eligibility
for  participation  in this Plan,  then such amendment  shall be approved by the
holders of a majority of the Company's  outstanding  capital stock  present,  or
represented,  and  entitled  to vote at a meeting  duly held for the  purpose of
approving  such  amendment.   For  purposes  of  this  Subsection   4.6(b),  any
cancellation  and  reissuance of Options at the same, or a new or lower,  Option
Price pursuant to Subsection  4.6(a) hereof shall not constitute an amendment of
the Plan.

         4.7      Time of Grant and Exercise.

                  (a)  Except  as the  Committee  or  Board of  Directors  shall
otherwise  determine,  the granting of an Option pursuant to the Plan shall take
place at the time of the  resolutions  adopted by the  Committee  granting  such
Option; provided,  however, that if the appropriate resolutions of the Committee
indicate that an Option is to be granted as of or at some future date,  the date
of grant shall be such future date.

                  (b) An  Option  shall  be  deemed  to be  exercised  when  the
Secretary  of the Company  receives  written  notice of such  exercise  from the
person  entitled to exercise  the Option,  together  with payment in full of the
purchase  price  made  in  accordance  with  Section  3.1 of this  Plan  and all
applicable withholding taxes.

         4.8      Privileges of Stock Ownership; Nondistributive Intent.

                  The holder of an Option shall not be entitled to the privilege
of stock  ownership  as to any shares of Common  Stock not  actually  issued and
delivered  to him or her.  Upon  exercise  of an Option,  unless a  registration
statement is in effect under the Securities Act of 1933, as amended, relating to
the Common Stock  issuable  upon  exercise and there is available for delivery a
prospectus  meeting the requirements of Section 10(a)(3) of said Act, the Common
Stock  may be issued  to the  option  holder  only if he or she  represents  and
warrants in writing to the Company and its counsel that the shares purchased are
being acquired for investment and not with a view to the resale or  distribution
thereof. No shares shall be issued upon the exercise of any Option  unless  and 


                                      -11-




until  there  shall  have  been  full   compliance   with  any  then  applicable
requirements of the Securities and Exchange Commission,  or any other regulatory
agencies  having  jurisdiction  over this Plan (and of any exchanges  upon which
stock of the Company may be listed).

         4.9      Issuance of Stock Certificates.

                  Upon exercise of an Option,  the person receiving Common Stock
shall be entitled to one stock  certificate  evidencing the shares acquired upon
such exercise;  provided,  however,  that any person who tenders Common Stock to
the  Company  in  payment  of a portion  or all of the  purchase  price of stock
purchased  upon  exercise  of an  Option,  shall  be  entitled  to  receive  two
certificates,  one representing a number of shares equal to the number of shares
exchanged for the stock acquired upon  exercise,  and another  representing  the
additional shares acquired upon exercise of the Option.

         4.10      Effective Date of this Plan.

                  This  Plan  shall,  subject  to its  adoption  by the Board of
Directors and the Company's  stockholders  in accordance with applicable law and
the Company's Certificate of Incorporation, be effective as of June 30, 1989.

         4.11      Expiration.

                  Unless previously  terminated by the Board of Directors,  this
Plan shall  expire at the close of  business  on the date that is ten (10) years
less one day from the date  executed  below and no Option shall be granted under
it  thereafter,  but such  expiration  shall not affect  any Option  theretofore
granted.

         4.12      Governing Law.

                  This Plan and the Options issued  hereunder  shall be governed
by,  and  construed  in  accordance  with,  the  laws of the  State  of New York
applicable  to contracts  made and performed  within such State,  except as such
laws may be supplanted  by the laws of the United States of America,  which laws
shall then govern its effect and its  construction  to the extent they  supplant
New York law.

                  EXECUTED as of the 14th day of February, 1997.

                                       SILGAN HOLDINGS INC.
