                   THIRD AMENDMENT TO 364-DAY CREDIT AGREEMENT

     THIS AMENDMENT (herein so called) is entered into as of April 24, 2003,
among FMC TECHNOLOGIES, INC., a Delaware corporation ("Borrower"), the Lenders
(as defined in the Credit Agreement) party to the Credit Agreement (hereinafter
defined) that continue as Lenders after giving effect to this Amendment, the
Persons that become Lenders pursuant to this Amendment and BANK OF AMERICA,
N.A., as Administrative Agent (as defined in the Credit Agreement) for the
Lenders.

     Borrower, the Lenders and the Administrative Agent are party to the 364-Day
Credit Agreement dated as of April 26, 2001, as amended by that certain First
Amendment to 364-Day Credit Agreement dated as of May 30, 2001 and that certain
Second Amendment to 364-Day Credit Agreement dated as of April 25, 2002 (as
amended, the "Credit Agreement"), and have agreed, upon the following terms and
conditions, to further amend the Credit Agreement in certain respects.
Accordingly, for valuable and acknowledged consideration, Borrower, the Lenders
and the Administrative Agent agree as follows:

     1. Terms and References. Unless otherwise stated in this Amendment, (a)
terms defined in the Credit Agreement have the same meanings when used in this
Amendment, and (b) references to "Sections," "Articles" and "Exhibits" are to
the Credit Agreement's sections, articles and exhibits.

     2. Amendments. The Credit Agreement is amended as follows:

          (a) Section 1.01 is amended to delete the definition of "Applicable
     Rate" in its entirety and substitute the following definition in lieu
     thereof:

               "Applicable Rate means the following percentages per annum, based
          upon the Debt Rating:

--------------------------------------------------------------------------------
                                 Applicable Rate
--------------------------------------------------------------------------------
                Debt Ratings
Pricing Level   S&P/Moody's    Facility Fee   Eurodollar Rate   Utilization Fee
--------------------------------------------------------------------------------
      1         **BBB+/Baa1        .125%             .500%            .125%
--------------------------------------------------------------------------------
      2            BBB/Baa2        .150%             .725%            .125%
--------------------------------------------------------------------------------
      3           BBB-/Baa3        .175%             .825%            .125%
--------------------------------------------------------------------------------
      4            *BB+/Ba1        .250%            1.000%            .125%
--------------------------------------------------------------------------------

** means greater than or equal to
*  means less than or equal to

          Debt Rating means, as of any date of determination, the rating as
          determined by either S&P or Moody's (collectively, the "Debt
          Ratings") of the Borrower's non-credit-enhanced, senior unsecured
          long-term debt; provided that if a Debt Rating is issued by each
          of the foregoing rating agencies, then the higher of such Debt
          Ratings shall apply (with Pricing Level 1 being the highest and
          Pricing Level 4 being the lowest), unless there is a split in
          Debt Ratings of more than one level, in which case the average
          Debt Rating (or the higher of two intermediate Debt Ratings)
          shall apply. If neither of the foregoing rating agencies issues a
          Debt Rating, Pricing Level 4 shall apply.

                                    Third Amendment to Credit Agreement - Page 1

<PAGE>

          Each change in the Applicable Rate resulting from a publicly
          announced change in a Debt Rating shall be effective during the
          period commencing on the date of the public announcement thereof
          and ending on the date immediately preceding the effective date
          of the next such change."

          (b) Section 1.01 is further amended to delete the definition of
     "Maturity Date" in its entirety and substitute the following definition in
     lieu thereof:

               "Maturity Date means (a) subject to extension pursuant to
          Section 2.03, April 22, 2004 or (b) such earlier date upon which
          the Commitments may be terminated in accordance with the terms
          hereof; provided that, if the Loans are converted to a term loan
          pursuant to Section 2.03(d), from and after such conversion,
          "Maturity Date" shall mean the first anniversary of the date on
          which such conversion occurs."

          (c) Article V is amended to add the following new Section 5.12:

               5.12 Tax Shelter Regulations. The Borrower does not intend
          to treat the Loans and related transactions as being a
          "reportable transaction" (within the meaning of Treasury
          Regulation Section 1.6011-4). In the event the Borrower
          determines to take any action inconsistent with such intention,
          it will promptly notify the Administrative Agent thereof. If the
          Borrower so notifies the Administrative Agent, the Borrower
          acknowledges that one or more of the Lenders may treat its Loans
          as part of a transaction that is subject to Treasury Regulation
          Section 301.6112-1, and such Lender or Lenders, as applicable,
          will maintain the lists and other records required by such
          Treasury Regulation.

          (d) Section 6.01 is amended by deleting Sections 6.01(i) and (j) and
     substituting the following Sections 6.01(i), (j), and (k) in lieu thereof:

               (i) as soon as practicable after a Principal Officer of the
          Borrower obtains knowledge of the commencement of an action, suit
          or proceeding against the Borrower or any Subsidiary before any
          court or arbitrator or any governmental body, agency or official
          in which there is a reasonable likelihood of an adverse decision
          which would have a Material Adverse Effect or which in any manner
          questions the validity or enforceability of this Agreement or any
          of the transactions contemplated hereby, information as to the
          nature of such pending or threatened action, suit or proceeding;

               (j) promptly after the Borrower has notified the
          Administrative Agent of any intention by the Borrower to treat
          the Loans and related transactions as being a "reportable
          transaction" (within the meaning of Treasury Regulation Section
          1.6011-4), a duly completed copy of IRS Form 8886 or any
          successor form; and

                                    Third Amendment to Credit Agreement - Page 2

<PAGE>

               (k) from time to time such additional information regarding
          the business, properties, financial position, results of
          operations, or prospects of the Borrower or any Subsidiary as the
          Administrative Agent, at the request of any Lender, may
          reasonably request.

          (e) Section 10.08 is amended to add the following sentence at the end
     thereof:

               Notwithstanding anything herein to the contrary,
          "Information" shall not include, and the Administrative Agent and
          each Lender may disclose without limitation of any kind, any
          information with respect to the "tax treatment" and "tax
          structure" (in each case, within the meaning of Treasury
          Regulation Section 1.6011-4) of the transactions contemplated
          hereby and all materials of any kind (including opinions or other
          tax analyses) that are provided to the Administrative Agent or
          such Lender relating to such tax treatment and tax structure
          other than information or materials for which nondisclosure is
          reasonably necessary in order to comply with applicable
          securities laws; provided that with respect to any document or
          similar item that in either case contains information concerning
          the tax treatment or tax structure of the transaction as well as
          other information, this sentence shall only apply to such
          portions of the document or similar item that relate to the tax
          treatment or tax structure of the Loans and transactions
          contemplated hereby.

          (f) Schedule 2.01 is entirely amended in the form of, and all
     references in the Credit Agreement to Schedule 2.01 are changed to, Amended
     Schedule 2.01 attached hereto. Each Person named on Amended Schedule 2.01
     that was not a party to the Credit Agreement prior to this Amendment hereby
     becomes a Lender and agrees to perform and be bound by the terms and
     provisions of the Credit Agreement, as amended hereby, and the other Loan
     Documents that are applicable to a Lender.

     3. Conditions Precedent to Effectiveness. This Amendment shall not be
effective until the Administrative Agent receives (a) counterparts of this
Amendment executed by Borrower, the Lenders and the Administrative Agent, (b)
such evidence as the Administrative Agent may reasonably request to verify that
Borrower is duly incorporated, validly existing and in good standing in its
jurisdiction of incorporation, (c) a certificate signed by a Principal Officer
of Borrower (i) certifying that there has been no event or circumstance since
December 31, 2002, which has had or could reasonably be expected to have a
Material Adverse Effect, (ii) showing the Debt Ratings of Borrower on the date
hereof, and (iii) stating that no amendments have been made to the certificate
of incorporation or bylaws of Borrower since April 30, 2001 or, if any such
amendments have been made, attaching true and correct copies of the certificate
of incorporation or bylaws of Borrower, as so amended, (d) a certificate signed
by a Principal Officer of Borrower certifying as to the incumbency of the
Principal Officer of Borrower executing this Amendment, and attaching true and
correct copies of resolutions adopted by the Board of Directors of Borrower
authorizing Borrower to enter into this Amendment and verifying the authority
and capacity of such Principal Officer to execute this Amendment, (e) an opinion
of James Marvin, Associate General Counsel and Assistant Secretary of Borrower,

this Amendment), which Note shall be in substitution and replacement of any Note
previously executed by Borrower and payable to such Lender pursuant to the

Credit Agreement, and (h) such other documents, instruments and certificates as
the Administrative Agent may reasonably request.

     4. Representations. Borrower represents and warrants to the Lenders that as

in Article V are true and correct in all material respects except to the extent
that such representations and warranties refer to an earlier date, in which case
they were true and correct in all material respects as of such earlier date, and
(b) no Default or Event of Default has occurred and is continuing.

     5. Effect of Amendment. This Amendment is a Loan Document. Except as
expressly modified and amended by this Amendment, all of the terms, provisions
and conditions of the Loan Documents shall remain unchanged and in full force
and effect. The Loan Documents and any and all other documents heretofore, now
or hereafter executed and delivered pursuant to the terms of the Credit
Agreement are hereby amended so that any reference to the Credit Agreement shall
mean a reference to the Credit Agreement as amended hereby.

     6. Counterparts. This Amendment may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed and delivered shall be deemed to be an original and all of
which taken together shall constitute one and the same instrument.

To Bank of America, N.A., as Administrative Agent,
   and each of the Lenders party to
   the Credit Agreement referred to below

Re: FMC Technologies, Inc.

Ladies and Gentlemen:

     I am the Associate General Counsel and Assistant Secretary of, and have
acted as counsel to, FMC Technologies, Inc. (the "Borrower") in connection with
the preparation, execution and delivery of, and the consummation of the
transactions contemplated by, the 364-Day Credit Agreement dated as of April 26,
2001, as amended by the First Amendment to 364-Day Credit Agreement dated as of
May 30, 2001, the Second Amendment to 364-Day Credit Agreement dated as of April
25, 2002, and the Third Amendment to 364-Day Credit Agreement dated as of April
24, 2003 (the "Third Amendment") (such Credit Agreement, as so amended, the
"Credit Agreement"), by and among the Borrower, the Lenders party thereto, and
Bank of America, N.A., as agent for the Lenders (the "Administrative Agent").

     This opinion is rendered to you pursuant to Section 4(b) of the Third
Amendment. Capitalized terms defined in the Credit Agreement, used herein, and
not otherwise defined herein, shall have the meanings given them in the Credit
Agreement.

     In so acting, I have examined originals or copies (certified or otherwise
identified to my satisfaction) of the following documents:

     1.   the Credit Agreement; and

     2.   the Third Amendment.

     The agreements specified in clauses (1) and (2) are collectively referred
to as the "Agreements."

     In addition, I have examined such corporate records, agreements, documents
and other instruments, and such certificates or comparable documents of public
officials and of officers and representatives of each of the Borrower, and have
made such inquiries of such officers and representatives, as I have deemed
relevant and necessary as a basis for the opinions hereinafter set forth.

     In such examination, I have assumed the genuineness of all signatures, the
legal capacity of all natural persons, the authenticity of all documents
submitted to me as originals, the conformity to original documents of all
documents submitted to me as certified, conformed or photostatic copies and the
authenticity of the originals of such latter documents. As to all questions of
fact material to the opinions

                                       A-1                             Exhibit A

<PAGE>

set forth herein that have not been independently established, I have relied
upon certificates or comparable documents of officers and representatives of the
Borrower and upon the representations and warranties of the Borrower contained
in the Agreements.

     I am licensed to practice law in the State of Illinois, and this opinion is
limited to the laws of the State of Illinois, the General Corporation Law of the
State of Delaware and the federal laws of the United States of America.

     Based on the foregoing, and subject to the qualifications stated herein, I
am of the opinion that:

1.   The Borrower is a corporation validly existing and in good standing under
     the law of the State of Delaware and has all requisite corporate power and
     authority to own, lease and operate its properties and to carry on its
     business as now being conducted.

2.   The Borrower is duly qualified to transact business and is in good standing
     as a foreign corporation in each jurisdiction where the failure to be so
     qualified would have a Material Adverse Effect.

3.   The Borrower has all requisite corporate power and authority to execute,
     deliver and perform the Agreements. The execution, delivery and performance
     by the Borrower of the Agreements have been duly authorized by all
     necessary corporate action on the part of the Borrower. The Borrower has
     duly executed and delivered the Agreements. An Illinois state court or a
     federal court sitting in the State of Illinois in a diversity action
     should, under conflicts of law principles observed by the courts of the
     State of Illinois, if properly presented with the issue, give effect to
     those provisions of the Agreements providing that the Agreements are to be
     governed by and construed in accordance with the law of the State of New
     York insofar as such provisions relate to the substantive laws of the State
     of New York and to the validity, nature, interpretation and effect of the
     Agreements, except (i) to the extent, if any, that federal law applies,
     (ii) to the extent procedural (as opposed to substantive) laws are
     involved, or (iii) to the extent that the applicable laws of New York
     violate a public policy of the State of Illinois.

4.   The execution, delivery and performance by the Borrower of the Agreements
     will not conflict with, constitute a default under or violate (i) any of
     the terms, conditions or provisions of the Certificate of Incorporation or
     By-laws of the Borrower, (ii) any of the terms, conditions or provisions of
     any material contractual obligation of the Borrower of which I am aware,
     (iii) any Illinois, Delaware corporate or federal requirement of law or
     (iv) any judgment, writ, injunction, decree, order or ruling of any court
     or governmental authority of which I am aware which is binding on the
     Borrower.

5.   No consent, approval, waiver, license or authorization or other action by
     or filing with any Illinois, Delaware corporate or federal Governmental
     Authority of which I am aware is required in connection with the execution,
     delivery or performance by the Borrower of the Agreements.

                                       A-2                             Exhibit A

<PAGE>

6.   The borrowings by and other financial accommodations provided to the
     Borrower under the Agreements and the application of proceeds thereof as
     provided in the Credit Agreement will not violate Regulation U or X of the
     Board.

7.   The Borrower is not an "investment company" within the meaning of the
     Investment Company Act of 1940, as amended, or a "holding company" or a
     "subsidiary company" of a "holding company" within the meaning of the
     Public Utility Holding Company Act of 1935, as amended.

8.   To my knowledge, there is no action, suit, proceeding, governmental
     investigation or arbitration, at law or in equity or before any
     governmental authority, pending or overtly threatened against the Borrower
     (i) with respect to any Agreement or challenging any of the Lenders' or the
     Administrative Agent's rights or remedies thereunder or (ii) which is
     reasonably likely to be adversely determined and, if so determined, would
     be reasonably likely to materially adversely affect the ability of the
     Borrower to perform its obligations under the Agreements.

     My opinion in Paragraph 4(iii) is based upon my review of those
requirements of law which in my experience are normally applicable to or
normally relevant in connection with transactions of the type provided for in
the Agreements. For purposes of my opinion in the last sentence of Paragraph 3,
I have assumed that New York law bears a reasonable relationship to the
transactions contemplated by the Agreements.

     The opinions expressed herein are effective only as of the date of this
opinion letter. I do not assume responsibility for updating this opinion letter
as of any date subsequent to the date of this opinion letter, and I assume no
responsibility for advising you of (i) any change with respect to any matter
described in this opinion letter or (ii) the discovery subsequent to the date of
this opinion letter of factual information not previously known to me pertaining
to events occurring prior to the date of this opinion letter.

     This opinion letter is rendered solely to you in connection with the
above-described transactions. This opinion letter may not be relied upon by you
for any other purpose, or relied upon by any other Person (other than your
successors and permitted assigns under the Credit Agreement) for any purpose,
without in each case my prior written consent.

                                Very truly yours,

                                ----------------------

                                       A-3                             Exhibit A

             , 2003
-------------

Bank of America, N.A.
   and each of the other financial
   institutions that is a party to the
   Credit Agreement referred to below
c/o Bank of America, N.A., as Administrative Agent
901 Main Street
Dallas, Texas 75202

Ladies and Gentlemen:

     We have acted as special New York counsel for FMC Technologies, Inc., a
Delaware corporation (the "Borrower"), in connection with the 364-Day Credit
Agreement dated as of April 26, 2001, as amended by the First Amendment to
364-Day Credit Agreement dated as of May 30, 2001, the Second Amendment to
364-Day Credit Agreement dated as of April 25, 2002, and the Third Amendment to
364-Day Credit Agreement dated as of April 24, 2003 (the "Third Amendment")
(such Credit Agreement, as so amended, the "Credit Agreement") among the
Borrower, various financial institutions and Bank of America, N.A., as
Administrative Agent. Terms defined in the Credit Agreement are used herein as
therein defined. This opinion letter is being rendered to you at the request of
our clients pursuant to the requirements of the Third Amendment.

     We have examined originals or copies, certified or otherwise identified to
our satisfaction, of (i) the Credit Agreement, (ii) the Third Amendment, and
(iii) such documents, corporate records, certificates of public officials and of
officers and representatives of the Borrower and other instruments, and have
conducted such other investigations of fact and law, as we have deemed necessary
or advisable for purposes of this opinion letter. Except as described in the
foregoing sentence, we have not undertaken any independent investigation of any
factual matters which might be relevant to this opinion letter and we have made
no independent investigation of the records of, or other matters relating to,
the Borrower or any other Person.

     For the purposes of this opinion letter, we have assumed that all items
submitted to us as originals are complete and authentic and all signatures
thereon are genuine, and all items submitted to us as copies are complete and
conform to the originals. We have also assumed, with your permission and without
independent investigation of any kind, the following: (i) the Borrower has been
duly incorporated and is validly existing and is in good standing under the laws
of the State of Delaware; (ii) the Borrower has the corporate power and
authority to execute, deliver and perform its obligations under the Third
Amendment and the Credit Agreement; (iii) the Borrower has the corporate power
and authority to execute, deliver and perform its obligations under the Third
Amendment and the Credit Agreement; (iv) the Borrower has taken all corporate
action required to duly authorize the execution, delivery and performance by it
of the Third Amendment and the Credit Agreement; (v) the Third Amendment and the
Credit Agreement have

                                       B-1

<PAGE>

been duly authorized, executed and delivered by the Borrower, (vi) the Third
Amendment and the Credit Agreement are the legal, valid and binding obligations
of each party thereto (other than the Borrower) enforceable against each such
party in accordance with its terms; (vii) the execution, delivery and
performance of the Third Amendment and the Credit Agreement by the Borrower (a)
are in accordance with (and do not conflict with) the laws of the State of
Delaware, (b) do not violate or contravene the organizational documents or
by-laws of the Borrower, and (c) do not violate or contravene any provision of
any agreement or contract applicable to or binding upon the Borrower; and (viii)
there are no agreements or understandings among the parties, written or oral,
and no usage of trade or course of prior dealing among the parties which would,
in either case, define, supplement or qualify the terms of the Third Amendment
or Credit Agreement.

     Upon the basis of the foregoing and the other assumptions and
qualifications set forth herein, we are of the opinion that:

     1. The Credit Agreement constitutes a valid and binding agreement of the
Borrower, enforceable in accordance with its terms.

     2. The Third Amendment constitutes a valid and binding agreement of the
Borrower, enforceable in accordance with its terms.

     Our opinions set forth above are subject to the following qualifications:

          or similar provision of law of any county, municipality, or similar
          political subdivision of the State of New York or any agency or
          instrumentality thereof, and we express no opinion as to any law to
          which the Borrower may be subject solely as a result of your legal or
          regulatory status or as to any insurance law or any federal or state
          securities or "blue sky" law. Members of our Firm are admitted to
          practice law in the State of New York and we express no opinion on any
          law other than the laws of the State of New York and the Federal law
          of the United States to the extent specifically set forth herein.

     (b)  Our opinions are subject to the effect of any applicable bankruptcy,
          insolvency, reorganization, moratorium, fraudulent conveyance or
          similar laws affecting creditors' rights generally and to the effect
          of general principles of equity (regardless of whether considered in a
          proceeding in equity or at law), including (without limitation)
          concepts of materiality, reasonableness, good faith and fair dealing
          and by limitations on the availability of specific performance,
          injunctive relief or other equitable remedies.

     (c)  We express no opinion as to:

               (i)  obligations  relating to  indemnification,  contribution  or

               (ii) the enforceability, under certain circumstances, of
          provisions imposing penalties or forfeitures, late payment charges or
          an increase in interest rate upon delinquency in payment or the
          occurrence of a default;

               (iii) any agreement by the Borrower to the subject matter

          right to jury trial or to be served with process by service upon a
          designated third party;

               (iv) any agreement by the Borrower purporting to waive any
          objection to the laying of venue or any claim that an action or
          proceeding has been brought in an inconvenient forum;

               (v) the effect of the law of any jurisdiction other than the
          State of New York wherein any Lender may be located or wherein the
          enforcement of the Third Amendment or the Credit Agreement may be
          sought that limits the rates of interest, fees or other charges
          legally chargeable or collectible;

               (vi) any provision of the Third Amendment or the Credit Agreement
          (A) restricting access to legal or equitable remedies, (B) relating to

          Amendment or the Credit Agreement may only be amended, modified or
          waived in writing, (D) stating that all rights or remedies of any
          party are cumulative and may be enforced in addition to any other
          right or remedy and that the election of a particular remedy does not
          preclude recourse to one or more remedies, (E) purporting to establish
          an evidentiary standard for determinations by the Lenders or the

                  THIRD AMENDMENT TO FIVE-YEAR CREDIT AGREEMENT
                  ---------------------------------------------

     THIS AMENDMENT (herein so called) is entered into as of April 24, 2003,
among FMC TECHNOLOGIES, INC., a Delaware corporation ("Borrower"), the Lenders
(herein so called) party to the Credit Agreement (hereinafter defined) and BANK
OF AMERICA, N.A., as Administrative Agent (as defined in the Credit Agreement)
for the Lenders.

     Borrower, the Lenders and the Administrative Agent are party to the
Five-Year Credit Agreement dated as of April 26, 2001, as amended by that
certain First Amendment to Five-Year Credit Agreement dated as of May 30, 2001
and that certain Second Amendment to Five-Year Credit Agreement dated as of
April 25, 2002 (as amended, the "Credit Agreement"), and have agreed, upon the
following terms and conditions, to further amend the Credit Agreement in certain
respects. Accordingly, for valuable and acknowledged consideration, Borrower,
the Lenders and the Administrative Agent agree as follows:

     1.   Terms and References. Unless otherwise stated in this Amendment, (a)
terms defined in the Credit Agreement have the same meanings when used in this
Amendment, and (b) references to "Sections", "Articles" and "Exhibits" are to
the Credit Agreement's sections, articles and exhibits.

     2.   Amendments.

          (a)  Section 1.01 is amended to delete the definition of "Letter of
     Credit Sublimit" in its entirety and substitute the following definition in
     lieu thereof:

               "Letter of Credit Sublimit means an amount equal to
          $100,000,000; provided that the Outstanding Amount of the
          L/C Obligations arising out of the issuance of Letters of
          Credit that are considered by the Administrative Agent, in
          the exercise of its sole discretion, to be "financial
          standby letters of credit", within the meaning of such
          phrase in the risk-based capital regulations set forth in
          Part 325 of Title 12 of the Code of Federal Regulations,
          shall not exceed an amount equal to $10,000,000. The Letter
          of Credit Sublimit is part of, and not in addition to, the
          Aggregate Commitments."

          (b)  Article V is amended to add the following new Section 5.12:

               5.12 Tax Shelter Regulations. The Borrower does not
          intend to treat the Loans and/or Letters of Credit and
          related transactions as being a "reportable transaction"
          (within the meaning of Treasury Regulation Section
          1.6011-4). In the event the Borrower determines to take any
          action inconsistent with such intention, it will promptly
          notify the Administrative Agent thereof. If the Borrower so
          notifies the Administrative Agent, the Borrower acknowledges
          that one or more of the Lenders may treat its Loans as part
          of a transaction that is subject to Treasury Regulation
          Section 301.6112-1, and such Lender or Lenders, as
          applicable, will maintain the lists and other records
          required by such Treasury Regulation.

<PAGE>

          (c)  Section 6.01 is amended by deleting Sections 6.01(i) and (j) and
     substituting the following Sections 6.01(i), (j), and (k) in lieu thereof:

               (i) as soon as practicable after a Principal Officer of
          the Borrower obtains knowledge of the commencement of an
          action, suit or proceeding against the Borrower or any
          Subsidiary before any court or arbitrator or any
          governmental body, agency or official in which there is a
          reasonable likelihood of an adverse decision which would
          have a Material Adverse Effect or which in any manner
          questions the validity or enforceability of this Agreement
          or any of the transactions contemplated hereby, information
          as to the nature of such pending or threatened action, suit
          or proceeding;

               (j) promptly after the Borrower has notified the
          Administrative Agent of any intention by the Borrower to
          treat the Loans and/or Letters of Credit and related
          transactions as being a "reportable transaction" (within the
          meaning of Treasury Regulation Section 1.6011-4), a duly
          completed copy of IRS Form 8886 or any successor form; and

               (k) from time to time such additional information
          regarding the business, properties, financial position,
          results of operations, or prospects of the Borrower or any
          Subsidiary as the Administrative Agent, at the request of
          any Lender, may reasonably request.

          (d)  Section 10.08 is amended to add the following sentence at the end
     thereof:

               Notwithstanding anything herein to the contrary,
          "Information" shall not include, and the Administrative
          Agent and each Lender may disclose without limitation of any
          kind, any information with respect to the "tax treatment"
          and "tax structure" (in each case, within the meaning of
          Treasury Regulation Section 1.6011-4) of the transactions
          contemplated hereby and all materials of any kind (including
          opinions or other tax analyses) that are provided to the
          Administrative Agent or such Lender relating to such tax
          treatment and tax structure other than information or
          materials for which nondisclosure is reasonably necessary in
          order to comply with applicable securities laws; provided
          that with respect to any document or similar item that in
          either case contains information concerning the tax
          treatment or tax structure of the transaction as well as
          other information, this sentence shall only apply to such
          portions of the document or similar item that relate to the
          tax treatment or tax structure of the Loans, Letters of
          Credit and transactions contemplated hereby.

     3.   Conditions Precedent to Effectiveness. This Amendment shall not be
effective until the Administrative Agent receives (a) counterparts of this
Amendment executed by Borrower, the Required Lenders and the Administrative
Agent, (b) such evidence as the Administrative Agent may reasonably request to
verify that Borrower is duly incorporated, validly existing and in good standing
in its

To Bank of America, N.A., as Administrative Agent,
     and each of the Lenders party to
     the Credit Agreement referred to below

Re:  FMC Technologies, Inc.

Ladies and Gentlemen:

     I am the Associate General Counsel and Assistant Secretary of, and have
acted as counsel to, FMC Technologies, Inc. (the "Borrower") in connection with
the preparation, execution and delivery of, and the consummation of the
transactions contemplated by, the Five-Year Credit Agreement dated as of April
26, 2001, as amended by the First Amendment to Five-Year Credit Agreement dated
as of May 30, 2001, the Second Amendment to Five-Year Credit Agreement dated as
of April 25, 2002, and the Third Amendment to Five-Year Credit Agreement dated
as of April 24, 2003 (the "Third Amendment") (such Credit Agreement, as so
amended, the "Credit Agreement"), by and among the Borrower, the Lenders party
thereto, and Bank of America, N.A., as agent for the Lenders (the
"Administrative Agent").

     This opinion is rendered to you pursuant to Section 4(b) of the Third
Amendment. Capitalized terms defined in the Credit Agreement, used herein, and
not otherwise defined herein, shall have the meanings given them in the Credit
Agreement.

     In so acting, I have examined originals or copies (certified or otherwise
identified to my satisfaction) of the following documents:

     1.   the Credit Agreement; and

     2.   the Third Amendment.

     The agreements specified in clauses (1) and (2) are collectively referred
to as the "Agreements."

     In addition, I have examined such corporate records, agreements, documents
and other instruments, and such certificates or comparable documents of public
officials and of officers and representatives of each of the Borrower, and have
made such inquiries of such officers and representatives, as I have deemed
relevant and necessary as a basis for the opinions hereinafter set forth.

     In such examination, I have assumed the genuineness of all signatures, the
legal capacity of all natural persons, the authenticity of all documents
submitted to me as originals, the conformity to original documents of all
documents submitted to me as certified, conformed or photostatic copies and the
authenticity of the originals of such latter documents. As to all questions of
fact material to the opinions set forth herein that have not been independently
established, I have relied upon certificates or comparable documents of officers
and representatives of the Borrower and upon the representations and warranties
of the Borrower contained in the Agreements.

                                       A-1                             Exhibit A
                                                                       ---------

     I am licensed to practice law in the State of Illinois, and this opinion is
limited to the laws of the State of Illinois, the General Corporation Law of the
State of Delaware and the federal laws of the United States of America.

     Based on the foregoing, and subject to the qualifications stated herein, I
am of the opinion that:

1.        The Borrower is a corporation validly existing and in good standing
          under the law of the State of Delaware and has all requisite corporate
          power and authority to own, lease and operate its properties and to
          carry on its business as now being conducted.

2.        The Borrower is duly qualified to transact business and is in good
          standing as a foreign corporation in each jurisdiction where the
          failure to be so qualified would have a Material Adverse Effect.

3.        The Borrower has all requisite corporate power and authority to
          execute, deliver and perform the Agreements. The execution, delivery
          and performance by the Borrower of the Agreements have been duly
          authorized by all necessary corporate action on the part of the
          Borrower. The Borrower has duly executed and delivered the Agreements.
          An Illinois state court or a federal court sitting in the State of
          Illinois in a diversity action should, under conflicts of law
          principles observed by the courts of the State of Illinois, if
          properly presented with the issue, give effect to those provisions of
          the Agreements providing that the Agreements are to be governed by and
          construed in accordance with the law of the State of New York insofar
          as such provisions relate to the substantive laws of the State of New
          York and to the validity, nature, interpretation and effect of the
          Agreements, except (i) to the extent, if any, that federal law
          applies, (ii) to the extent procedural (as opposed to substantive)
          laws are involved, or (iii) to the extent that the applicable laws of
          New York violate a public policy of the State of Illinois.

4.        The execution, delivery and performance by the Borrower of the
          Agreements will not conflict with, constitute a default under or
          violate (i) any of the terms, conditions or provisions of the
          Certificate of Incorporation or By-laws of the Borrower, (ii) any of
          the terms, conditions or provisions of any material contractual
          obligation of the Borrower of which I am aware, (iii) any Illinois,
          Delaware corporate or federal requirement of law or (iv) any judgment,
          writ, injunction, decree, order or ruling of any court or governmental
          authority of which I am aware which is binding on the Borrower.

5.        No consent, approval, waiver, license or authorization or other action
          by or filing with any Illinois, Delaware corporate or federal
          Governmental Authority of which I am aware is required in connection
          with the execution, delivery or performance by the Borrower of the
          Agreements.

6.        The borrowings by and other financial accommodations provided to the
          Borrower under the Agreements and the application of proceeds thereof
          as provided in the Credit Agreement will not violate Regulation U or X
          of the Board.

                                       A-2                             Exhibit A
                                                                       ---------

7.        The Borrower is not an "investment company" within the meaning of the
          Investment Company Act of 1940, as amended, or a "holding company" or
          a "subsidiary company" of a "holding company" within the meaning of
          the Public Utility Holding Company Act of 1935, as amended.

8.        To my knowledge, there is no action, suit, proceeding, governmental
          investigation or arbitration, at law or in equity or before any
          governmental authority, pending or overtly threatened against the
          Borrower (i) with respect to any Agreement or challenging any of the
          Lenders' or the Administrative Agent's rights or remedies thereunder
          or (ii) which is reasonably likely to be adversely determined and, if
          so determined, would be reasonably likely to materially adversely
          affect the ability of the Borrower to perform its obligations under
          the Agreements.

     My opinion in Paragraph 4(iii) is based upon my review of those
requirements of law which in my experience are normally applicable to or
normally relevant in connection with transactions of the type provided for in
the Agreements. For purposes of my opinion in the last sentence of Paragraph 3,
I have assumed that New York law bears a reasonable relationship to the
transactions contemplated by the Agreements.

     The opinions expressed herein are effective only as of the date of this
opinion letter. I do not assume responsibility for updating this opinion letter
as of any date subsequent to the date of this opinion letter, and I assume no
responsibility for advising you of (i) any change with respect to any matter
described in this opinion letter or (ii) the discovery subsequent to the date of
this opinion letter of factual information not previously known to me pertaining
to events occurring prior to the date of this opinion letter.

     This opinion letter is rendered solely to you in connection with the
above-described transactions. This opinion letter may not be relied upon by you
for any other purpose, or relied upon by any other Person (other than your
successors and permitted assigns under the Credit Agreement) for any purpose,
without in each case my prior written consent.

                                Very truly yours,

                                       A-3                             Exhibit A
                                                                       ---------

     Credit Agreement referred to below
c/o Bank of America, N.A., as Administrative Agent
901 Main Street
Dallas, Texas 75202

Ladies and Gentlemen:

     We have acted as special New York counsel for FMC Technologies, Inc., a
Delaware corporation (the "Borrower"), in connection with the Five-Year Credit
Agreement dated as of April 26, 2001, as amended by the First Amendment to
Five-Year Credit Agreement dated as of May 30, 2001, the Second Amendment to
Five-Year Credit Agreement dated as of April 25, 2002, and the Third Amendment
to Five-Year Credit Agreement dated as of April 24, 2003 (the "Third Amendment")
(such Credit Agreement, as so amended, the "Credit Agreement") among the
Borrower, various financial institutions and Bank of America, N.A., as
Administrative Agent. Terms defined in the Credit Agreement are used herein as
therein defined. This opinion letter is being rendered to you at the request of
our clients pursuant to the requirements of the Third Amendment.

     We have examined originals or copies, certified or otherwise identified to
our satisfaction, of (i) the Credit Agreement, (ii) the Third Amendment, and
(iii) such documents, corporate records, certificates of public officials and of
officers and representatives of the Borrower and other instruments, and have
conducted such other investigations of fact and law, as we have deemed necessary
or advisable for purposes of this opinion letter. Except as described in the
foregoing sentence, we have not undertaken any independent investigation of any
factual matters which might be relevant to this opinion letter and we have made
no independent investigation of the records of, or other matters relating to,
the Borrower or any other Person.

     For the purposes of this opinion letter, we have assumed that all items
submitted to us as originals are complete and authentic and all signatures
thereon are genuine, and all items submitted to us as copies are complete and
conform to the originals. We have also assumed, with your permission and without
independent investigation of any kind, the following: (i) the Borrower has been
duly incorporated and is validly existing and is in good standing under the laws
of the State of Delaware; (ii) the Borrower has the corporate power and
authority to execute, deliver and perform its obligations under the Third
Amendment and the Credit Agreement; (iii) the Borrower has the corporate power
and authority to execute, deliver and perform its obligations under the Third
Amendment and the Credit Agreement; (iv) the Borrower has taken all corporate
action required to duly authorize the execution, delivery and performance by it
of the Third Amendment and the Credit Agreement; (v) the Third Amendment and the
Credit Agreement have been duly authorized, executed and delivered by the
Borrower, (vi) the Third Amendment and the Credit Agreement are the legal, valid
and binding obligations of each party thereto (other than the Borrower)

                                       B-1                             Exhibit B
                                                                       ---------

enforceable against each such party in accordance with its terms; (vii) the
execution, delivery and performance of the Third Amendment and the Credit
Agreement by the Borrower (a) are in accordance with (and do not conflict with)
the laws of the State of Delaware, (b) do not violate or contravene the
organizational documents or by-laws of the Borrower, and (c) do not violate or
contravene any provision of any agreement or contract applicable to or binding
upon the Borrower; and (viii) there are no agreements or understandings among
the parties, written or oral, and no usage of trade or course of prior dealing
among the parties which would, in either case, define, supplement or qualify the
terms of the Third Amendment or Credit Agreement.

     Upon the basis of the foregoing and the other assumptions and
qualifications set forth herein, we are of the opinion that:

     1.   The Credit Agreement constitutes a valid and binding agreement of the
Borrower, enforceable in accordance with its terms.

     2.   The Third Amendment constitutes a valid and binding agreement of the
Borrower, enforceable in accordance with its terms.

     Our opinions set forth above are subject to the following qualifications:

     (a)  We express no opinion as to any law, rule, regulation, ordinance, code
          or similar provision of law of any county, municipality, or similar
          political subdivision of the State of New York or any agency or
          instrumentality thereof, and we express no opinion as to any law to
          which the Borrower may be subject solely as a result of your legal or
          regulatory status or as to any insurance law or any federal or state
          securities or "blue sky" law. Members of our Firm are admitted to
          practice law in the State of New York and we express no opinion on any
          law other than the laws of the State of New York and the Federal law
          of the United States to the extent specifically set forth herein.

     (b)  Our opinions are subject to the effect of any applicable bankruptcy,
          insolvency, reorganization, moratorium, fraudulent conveyance or
          similar laws affecting creditors' rights generally and to the effect
          of general principles of equity (regardless of whether considered in a
          proceeding in equity or at law), including (without limitation)
          concepts of materiality, reasonableness, good faith and fair dealing
          and by limitations on the availability of specific performance,
          injunctive relief or other equitable remedies.

     (c)  We express no opinion as to:

               (i)    obligations relating to indemnification, contribution or
          exculpation of costs, expenses or liabilities which contravene public
          policy;

               (ii)   the enforceability, under certain circumstances, of
          provisions imposing penalties or forfeitures, late payment charges or
          an increase in interest rate upon delinquency in payment or the
          occurrence of a default;

                                       B-2                             Exhibit B
                                                                       ---------

<PAGE>

               (iii)  any agreement by the Borrower to the subject matter
          jurisdiction of a United States federal court, to the waiver of the
          right to jury trial or to be served with process by service upon a
          designated third party;

               (iv)   any agreement by the Borrower purporting to waive any
          objection to the laying of venue or any claim that an action or
          proceeding has been brought in an inconvenient forum;

               (v)    the effect of the law of any jurisdiction other than the
          State of New York wherein any Lender may be located or wherein the
          enforcement of the Third Amendment or the Credit Agreement may be
          sought that limits the rates of interest, fees or other charges
          legally chargeable or collectible;

               (vi)   any provision of the Third Amendment or the Credit
          Agreement (A) restricting access to legal or equitable remedies, (B)
          relating to severability or similar clauses, (C) providing that the
          Third Amendment or the Credit Agreement may only be amended, modified
          or waived in writing, (D) stating that all rights or remedies of any
          party are cumulative and may be enforced in addition to any other
          right or remedy and that the election of a particular remedy does not
          preclude recourse to one or more remedies, (E) purporting to establish
          an evidentiary standard for determinations by the Lenders or the
          Administrative Agent or (F) purporting to convey rights to Persons
          other than parties to the Third Amendment or the Credit Agreement;

               (vii)  whether any court outside the State of New York would
          honor the choice of New York law as the governing law of the Third
          Amendment and the Credit Agreement; or

               (viii) Section 10.09 of the Credit Agreement.
