                                    AMENDMENT

      Amendment, dated as of March 13, 2000 ("this Amendment"), to the Corporate
Agreement,  dated as of December  2, 1997 (the  "Corporate  Agreement"),  by and
among Cordant Technologies Inc. (formerly named Thiokol Corporation), a Delaware
corporation  ("Cordant"),  Cordant  Technologies Holding Company (formerly named
Thiokol Holding Company),  a Delaware  corporation and a wholly owned subsidiary
of Cordant  ("Holding"),  and Howmet  International Inc., a Delaware corporation
(the  "Company")  (individually,  a "Party" and  collectively,  the  "Parties").
Capitalized  terms used but not defined herein shall have the meanings  ascribed
in the Corporate Agreement.

      WHEREAS, the Parties desire to amend the Corporate Agreement;

      NOW,  THEREFORE,  in  consideration  of  the  above  premises  and  mutual
agreements set forth in this Amendment, the Parties hereby agree as follows.

1. Article I of the Corporate  Agreement is hereby  amended and restated to read
as follows:

      Neither  Cordant,  Holding  nor  any of  their  Affiliates  shall  acquire
      Publicly held Shares (as defined  below) if, after such  acquisition,  the
      number of Publicly  Held Shares would be less than 14% of the total number
      of shares of Common Stock outstanding other than:

      (i)   with the  consent  of a  majority  (but not  less  than  two) of the
            non-employee  directors  of the  Company  who are not  directors  or
            employees of Cordant, Holding or their respective Affiliates, or

      (ii)  the purchase of at least a majority of the  outstanding  Publicly
            Held Shares pursuant to a tender offer to acquire all of the
            Publicly Held Shares,  which  tender  offer  (A) is  conditioned
            upon  there  being tendered and not  withdrawn  prior to the
            expiration of the offer not less than a majority  of the outstanding
            Publicly  Held  Shares (the "Minimum  Tender  Condition"),  and (B)
            provides a  commitment  for a prompt merger or business combination
            following the purchase of shares in the tender offer as contemplated
            by the following clause (iii), or

      (iii) pursuant to a merger or other business combination,  within one year
            following the completion of a tender offer  described in clause (ii)
            that satisfied the Minimum Tender Condition,  in which each Publicly
            Held Share  outstanding  immediately prior to  the effective time of
            such merger or business  combination  is converted into the right to
            receive the same  consideration  paid or issued in the tender offer,
            or

      (iv)  pursuant to a merger or other business  combination in which holders
            of all  outstanding  Publicly Held Shares are treated the same which
            is approved by the holders of a majority of the outstanding Publicly
            Held Shares.
<PAGE>

      For  purposes  of this  ARTICLE  I,  "Publicly  Held  Shares"  shall  mean
      outstanding  shares of Common  Stock  other than  shares  held by Cordant,
      Holding or any of their Affiliates.

      2. This  Amendment  shall be governed by and construed in accordance  with
the  substantive  and  procedural  laws of the State of New York  applicable  to
agreements  made and to be performed  entirely within such State (without giving
effect to any conflict of laws principles which might require application of the
law of a different jurisdiction).

      3. Except as expressly set forth herein,  this  Amendment to the Corporate
Agreement shall not by implication or otherwise alter,  modify,  amend or in any
way affect any of the terms,  conditions,  obligations,  covenants or agreements
contained in the Corporate  Agreement, all of which are ratified and affirmed in
all respects and shall continue in full force and effect.

      4. This Amendment may be executed by the Parties in separate counterparts,
each of which when so executed and delivered shall be an original,  but all such
counterparts shall together constitute one and the same instrument.

<PAGE>

      IN WITNESS  WHEREOF,  the Parties hereto have caused this instrument to be
duly executed on the date first above written.

Gentlemen:

     Reference is made to the Corporate Agreement, dated as of December 2, 1997,
as  amended  by the  Amendment,  dated as of March  13,  2000 (as  amended,  the
"Corporate  Agreement"),  by and among Cordant Technologies Inc. (formerly named
Thiokol Corporation),  a Delaware corporation ("Cordant"),  Cordant Technologies
Holding Company (formerly named Thiokol Holding Company), a Delaware corporation
and a wholly owned subsidiary of Cordant  ("Holding"),  and Howmet International
Inc., a Delaware corporation (the "Company").

     We hereby agree to comply with Article I of the Corporate  Agreement to the
same extent as if we were  Cordant  unless and until the  Agreement  and Plan of
Merger, to be dated as of March 14, 2000 (the "Merger Agreement"),  by and among
Alcoa Inc. ("Alcoa"), Omega Acquisition  Corp. (the  "Purchaser") and Cordant is
terminated  prior to our purchase of Cordant  shares in the Offer (as defined in
the Merger Agreement).

     This letter  agreement is given in  consideration of the Board of Directors
of the Company approving for purposes of Section 203 of the General  Corporation
Law of  the  State  of  Delaware  ("DGCL")  Alcoa  and  the  Purchaser  becoming
"interested stockholders" pursuant to Alcoa's execution of this letter agreement
or their entry into an agreement  with Cordant  providing  for a tender offer by
the Purchaser to acquire the outstanding shares of common stock, par value $1.00
per share,  of Cordant (the " Cordant  Common  Stock") and the  preferred  share
purchase  rights  issued or issuable  under the Cordant  Rights  Agreement  (the
"Rights," and together with Cordant Common Stock, the "Shares"),  to be followed
by  a  merger  in  which  they  would  acquire  the  remaining  Shares  and  the
consummation  of such  transactions  and the Board of  Directors  of the Company
taking all  appropriate  action so that Section 203 of the DGCL, with respect to
the Company, will not be applicable to Alcoa and the Purchaser by virtue of such
actions.

                                      1
<PAGE>

     This letter agreement shall be governed by New York law, without  reference
to its conflict of law principles.

     Please  confirm your  agreement  with the foregoing by signing the enclosed
copy of this letter agreement and returning it to us, whereupon it will become a
binding agreement.

Very truly yours,

ALCOA INC.

Governing Law: This Grant Agreement, the Notice, and the Plan shall be construed

stock  option  or the  exercise  of this  option  in whole or in part is  deemed
compensation,  the compensation  derived from this option shall not be construed
as  compensation  or income for determining the level of benefits from any other
