EXHIBIT 10.37


                        AMENDMENT TO EMPLOYMENT AGREEMENT



         The EMPLOYMENT AGREEMENT dated September 12, 2005, between PALL
CORPORATION, a New York Corporation (the "Company") and the undersigned, ROBERTO
PEREZ ("Executive"), as the same may have heretofore been amended, is hereby
amended, effective as of the date set forth below, by adding a new section
reading and providing as follows:

                  ss.15. Delay in Payment. Notwithstanding any provision in this
         Agreement to the contrary, any payment otherwise required to be made
         hereunder to Executive at any date shall be delayed for such period of
         time as may be necessary to meet the requirements of section
         409A(a)(2)(B)(i) of the Internal Revenue Code of 1986 as amended (the
         "Code"). On the earliest date on which any payments so delayed can be
         made without violating the requirements of section 409A(a)(2)(B)(i) of
         the Code (the "Delayed Payment Date"), there shall be paid to Executive
         (or if Executive has died, to "Executive's Successor" as the quoted
         term is defined below), in a single cash lump sum, an amount equal to
         the aggregate amount of all payments delayed pursuant to the preceding
         sentence, plus interest thereon at the Delayed Payment Interest Rate
         (as defined below) computed from the date on which each such delayed
         payment otherwise would have been made to Executive until the Delayed
         Payment Date. For purposes of the foregoing: (i) "Executive's
         Successor" shall mean such payee or payees as Executive shall at any
         time designate by written notice to the Company or in his last will and
         testament or, if no such designation is made, then to the legal
         representatives of Executive's estate, and (ii) the "Delayed Payment
         Interest Rate" shall mean the national average annual rate of interest
         payable on jumbo six-month bank certificates of deposit, as quoted in
         the business section of the most recently published Sunday edition of
         the New York Times preceding the date as of which Executive is treated
         as having incurred a "separation from service" for purposes of section
         409A(a)(2)(B)(i).

         IN WITNESS WHEREOF the parties hereto have executed this Amendment as
of and effective July 18, 2006.
