            FIRST AMENDMENT TO EXECUTIVE CHANGE OF CONTROL AGREEMENT
            --------------------------------------------------------

     THIS FIRST AMENDMENT TO EXECUTIVE CHANGE OF CONTROL AGREEMENT ("Amendment")
is made as of the 7th day of December 2001 by and between CIRCOR, Inc., a
Massachusetts company (the "Company") and Alan J. Glass ("Executive").

     WHEREAS, the Company and the Executive are parties to that certain
Executive Change of Control Agreement made as of the 8th day of August, 2000
(the "Agreement") pursuant to which the Executive serves as an officer of the
Company and CIRCOR International, Inc., a Delaware corporation of which the
Company is a wholly-owned subsidiary (the "Parent"); and

     WHEREAS, the Company and the Executive desire to amend the Agreement solely
to the extent set forth herein.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties agree as follows:

     1. Section 1 Definitions defines "Good Reason" for the purpose of the
Agreement to mean that Executive has complied with the "Good Reason Process"
(hereinafter defined) following the occurrence of any of the following events:
(A) a substantial diminution or other substantive adverse change, not consented
to by Executive, in the nature or scope of Executive's responsibilities,
authorities, powers, functions or duties; (B) any removal, during the term of
this Agreement, from Executive of his titles as an officer of the Parent; (C) an
involuntary reduction in Executive's Base Salary except for across-the-board
reductions similarly affecting all or substantially all management employees;
(D) a breach by the Company of any of its other material obligations under this
Agreement and the failure of the Company to cure such breach within thirty (30)
days after written notice thereof by Executive; or (E) the involuntary
relocation of the Company's offices at which Executive is principally employed
or the involuntary relocation of the offices of Executive's primary workgroup to
a location more than thirty (30) miles from such offices, or the requirement by
the Company that Executive be based anywhere other than the Company's offices at
such location on an extended basis, except for required travel on the Company's
business to an extent substantially consistent with Executive's business travel
obligations. That definition is hereby deleted and replaced with the following
definition:

          For purposes of this Agreement, "Good Reason" shall mean that
          Executive has complied with the "Good Reason Process" (hereinafter
          defined) following the occurrence of any of the following events: (A)
          a substantial diminution or other substantive adverse change, not
          consented to by Executive, in the nature or scope of Executive's
          responsibilities, authorities, powers, functions or duties; (B) any
          removal, during the term of this Agreement, from Executive of his
          titles as an officer of Parent; (C) an involuntary reduction in
          Executive's Base Salary except for across-the-board reductions
          similarly affecting all or substantially all management employees; (D)
          a breach by the Company of any of its other material obligations under
          this Agreement and the failure of the Company to cure such breach
          within thirty (30) days after written notice thereof by Executive; (E)
          the involuntary relocation of the Company's offices at which Executive
          is principally employed or the involuntary relocation of the offices
          of Executive's primary workgroup to a location more than thirty (30)
          miles from such offices, or the requirement by the Company that
          Executive be based anywhere other than the Company's offices at such
          location on an extended basis, except for required travel on the
          Company's business to an extent substantially consistent with
          Executive's business travel obligations; or (F) a reduction in
          Executive's opportunity for annual incentive compensation below the
          annual incentive opportunity most recently in effect under the
          Company's Executive Bonus Incentive Plan prior to the Change in
          Control

     2.   Section 3(a)(i) is hereby deleted in its entirety and replaced with
          the following:

<PAGE>

          If within twelve (12) months after the occurrence of the first event
          constituting a Change in Control, Executive's employment is terminated
          by the Company without Cause as defined in Section 1 or Executive
          terminates his employment for Good Reason as provided in Section 1,
          then the Company shall pay Executive a lump sum in cash in an amount
          equal to one (1) times the sum of (A) Executive's current Base Salary
          plus (B) Executive's highest annual incentive compensation under the
          Company's Executive Bonus Incentive Plan in the three (3) immediately
          preceding fiscal years, excluding any sign-on bonus, retention bonus
          or any other special bonus; and

     3.   Except as specifically amended hereby, the Agreement remains in full
force and effect according to its terms.

     4.   This Amendment may be executed in any number of counterparts, each of
which shall be deemed an original, but all of which constitute one instrument.
