                                                    WITNESSETH:
         WHEREAS,  Interlake and  Continental  Illinois  National Bank and Trust
Company of Chicago,  a national  banking  association  ("Continental  Illinois")
established  a trust (the  "Trust")  pursuant to an  agreement  entitled  "TRUST

         WHEREAS, Trustee is the successor to Continental Illinois as
trustee of the Trust;
         WHEREAS,  Interlake has transferred  assets to the Trust that are being
held in trust by the Trustee, all pursuant to the terms of the Agreement;
         WHEREAS,  in accordance with Section 12(a) of the Agreement,  Interlake
and the Trustee desire to amend the Agreement in certain respects,  as set forth
in this First Amendment,
         NOW, THEREFORE, the parties do hereby agree that the Agreement shall be
amended as follows:
         1. The  introductory  paragraph  of the  preamble of the  Agreement  is
amended by deleting  "(the  "Trustee")"  at the end thereof and by  substituting
therefor the following:

                                                        -1-





         ("Continental Illinois"), and amended as of the 17th
         day of February, 1998, pursuant to the First Amendment
         to Trust Agreement between Interlake and U.S. Trust
         Company of California, N.A. (the "Trustee"), as
         successor to Continental Illinois.
         2.       The first paragraph of the preamble of the Agreement is
amended in its entirety to read as follows:
                  WHEREAS, certain benefits are or may become
         payable  under the  provisions of The  Interlake  Corporation  Restated
         Directors' Post-Retirement Income Plan, established as of May 29, 1986,
         as the same has  been or may  hereafter  be  supplemented,  amended  or
         restated, or any successor thereto (the "Plan"), to certain individuals
         listed  on  Exhibit  A hereto  ("Directors");  3.  Section  1(a) of the
         Agreement is amended by adding the
following after the first sentence thereof:
         Neither the Trustee nor any Director or beneficiary
         shall have any right or duty to compel such additional
         deposits or determine the sufficiency thereof.
         4.       Section 1(c) of the Agreement is amended by adding the
following at the end thereof:
         The purpose of the Trust is to assure that  Interlake's  obligations to
         the Directors pursuant to the Plan are fulfilled.  The Trust is neither
         intended nor designed to qualify under section 401(a) of the Code or to
         be subject to the provisions of the Employee Retirement Income Security
         Act of 1974, as amended  ("ERISA").  The Trust  established  under this
         Agreement  does not fund  and is not  intended  to fund the Plan or any
         other employee benefit plan or program of Interlake.  Such Trust is and
         is intended  to be a  depository  arrangement  with the Trustee for the
         setting  aside of cash and other assets of Interlake for the meeting of
         part or all of its future  obligations with respect to Benefits to some
         or all of the  Directors  under the Plan. 5. Section 1 of the Agreement
         is amended by adding the
following provisions at the end thereof:
                  (d) Interlake shall transfer sufficient assets to the Trust on
         or prior to the date on which  occurs a Change in Control (as that term
         is defined in Section  1(e)) so that,  in  combination  with the assets
         theretofore held in the Trust, the aggregate assets

                                                        -2-





         held in the Trust equals or exceeds (i) an amount sufficient to satisfy
         all expenses with respect to the Trust, including,  without limitation,
         the fees of the Trustee,  for a period of at least five years, and (ii)
         the amount  estimated  by  Interlake  to be  necessary  to satisfy  all
         obligations under the Plan.

                  (e) As used in this  Agreement,  the term  "Change in Control"
         shall mean:

                             (i)   Interlake   is   merged,    consolidated   or
                  reorganized  into or with another  corporation  or other legal
                  person  and as a  result  of  such  merger,  consolidation  or
                  reorganization  less than 75% of the combined  voting power of
                  the  then-outstanding  securities of such other corporation or
                  person  immediately  after  such  transaction  are held in the
                  aggregate  by the holders of the  then-outstanding  securities
                  entitled to vote  generally in the election of directors  (the
                  "Voting  Stock")  of  Interlake   immediately  prior  to  such
                  transaction;

                            (ii) Interlake  sells or otherwise  transfers all or
                  substantially  all of its  business  or  assets  to any  other
                  corporation  or other  legal  person,  and as a result of such
                  sale or transfer,  less than 75% of the combined  voting power
                  of  the  then-outstanding  voting  securities  of  such  other
                  corporation or entity  immediately after such sale or transfer
                  are held in the  aggregate  by the holders of Voting  Stock of
                  Interlake immediately prior to such sale or transfer;

                           (iii) A  Share  Acquisition  Date  occurs  under  the
                  Rights Agreement, dated as of January 26, 1989, by and between
                  Interlake and The First National Bank of Chicago,  as amended,
                  or under any successor  rights agreement to which Interlake is
                  a party (the "Rights Agreement");  or, if the Rights Agreement
                  has expired  prior to the  occurrence  of a Share  Acquisition
                  Date,  any event that would  have  caused a Share  Acquisition
                  Date to occur under the Rights Agreement;

                            (iv) Any  person  (as the term  "person"  is used in
                  Section   13(d)(3)  or  Section  14(d)(2)  of  the  Securities
                  Exchange  Act of 1934 (the  "Exchange  Act"))  has  become the
                  beneficial  owner (as the term  "beneficial  owner" is defined
                  under  Rule  13d-3  or  any   successor   rule  or  regulation
                  promulgated under the Exchange Act) of securities representing
                  35% or more of the  combined  voting power of the Voting Stock
                  of Interlake;


                                                        -3-





                             (v)  Interlake  files a report  or proxy  statement
                  with the  Securities and Exchange  Commission  pursuant to the
                  Exchange  Act  disclosing  in, or in response  to, Form 8-K or
                  Schedule  14A (or any  successor  schedule,  form or report or
                  item therein) that a change in control of Interlake has or may
                  have  occurred  or will  occur in the future  pursuant  to any
                  then-existing contract or transaction; or

                            (vi) If during any period of two consecutive  years,
                  individuals who at the beginning of any such period constitute
                  the directors of Interlake  cease for any reason to constitute
                  at  least a  majority  thereof;  provided,  however,  that for
                  purposes of this Section 1(e)(vi),  each director who is first
                  elected,  or  first  nominated  for  election  by  Interlake's
                  stockholders,  by  a  vote  of  at  least  two-thirds  of  the
                  directors of Interlake (or a committee  thereof) then still in
                  office who were directors of Interlake at the beginning of any
                  such  period  will  be  deemed  to  have  been a  director  of
                  Interlake at the beginning of such period.

                           (vii)  Notwithstanding  the  foregoing  provisions of
                  Section   1(e)(iv)  or  1(e)(v)   hereof,   unless   otherwise
                  determined in a specific case by majority vote of the Board of
                  Directors  of  Interlake  (the  "Board"),  a Change in Control
                  shall not be deemed to have  occurred  for purposes of Section
                  1(e)(iv)  or 1(e)(v)  solely  because  (a)  Interlake,  (b) an
                  entity   in   which   Interlake,   directly   or   indirectly,
                  beneficially owns 50% or more of the voting securities of such
                  entity  (an  "Affiliate"),   or  (c)  any  Interlake-sponsored
                  employee stock  ownership  plan or any other employee  benefit
                  plan of  Interlake  or any  Affiliate  either files or becomes
                  obligated  to file a report or a proxy  statement  under or in
                  response to Schedule 13D, Schedule 14D-1, Form 8-K or Schedule
                  14A  (or  any  successor  schedule,  form  or  report  or item
                  therein)  under  the  Exchange  Act,   disclosing   beneficial
                  ownership by it of shares of Voting  Stock,  whether in excess
                  of 35% or  otherwise,  or  because  Interlake  reports  that a
                  change in control of  Interlake  has or may have  occurred  or
                  will or may occur in the  future by reason of such  beneficial
                  ownership.

                  (f) In the event that a Change in Control  has  occurred,  the
         Chief Executive Officer,  Chief Financial Officer or General Counsel of
         Interlake  shall so notify the Trustee  promptly.  The Trustee shall be
         entitled to rely upon such notice as to whether and when a Change

                                                        -4-





         in Control has occurred and shall not be required to
         make any independent verification of a Change in
         Control.

         6.       Section 2(a) of the Agreement is amended by adding the
following at the end thereof:
                  The Trustee  shall  continue to pay Benefits to the  Directors

         its execution of its duties under this  Agreement,  or by reason of any
         acts taken in good faith in  accordance  with any  directions,  or acts
         omitted in good faith due to absence of directions, from Interlake or a
         Director unless, and only to the extent,  such loss or liability is due
