EXHIBIT 10.4 PALL CORPORATION MANAGEMENT STOCK PURCHASE PLAN _____ 1. PURPOSE. This document sets forth the Pall Corporation Management Stock Purchase Plan as amended and restated effective as of January 1, 2005.

CREDITING OF RESTRICTED UNITS. For each Plan Year, Eligible Employees shall be credited with Restricted Units in accordance with the following provisions: (a) INITIAL AWARD UNITS. To the extent that the Compensation Committee in its sole discretion so determines, any Employee who is designated as an Eligible Employee for the first time at any time after August 1, 1999 shall be credited, as of the date specified by the Compensation Committee in such determination, with such number of Restricted Units as the Compensation Committee may determine for such Employee, or the Compensation Committee may determine not to grant any Initial Award Units to such Eligible Employee. -5- (b) BONUS UNITS. Each Employee who is an Eligible Employee for any Plan Year beginning on or after August 1, 1999 may elect to have any part or all of any Bonus that may become payable to the Participant during such year paid in the form of Restricted Units that will be credited to his or her Account hereunder and distributed in accordance with the provisions of this Plan, instead of being paid to the Eligible Employee in cash. If an Eligible Employee has so elected, the Eligible Employee's Account shall be credited on the first Bonus Payment Date during such year with a number of Restricted Units determined by dividing (i) the total amount of the portion of the Eligible Employee's Bonus payable during such year which the Eligible Employee elected to have paid in the form of Restricted Units, by (ii) the Closing Price of a share of Common Stock on such Bonus Payment Date or, if such date is not a Trading Day, on the next following day that is a Trading Day. In the event that an Eligible Employee's Bonus is payable in a unit of currency other than U.S. dollars, the portion of the bonus which the Eligible Employee has elected to have paid in the form of Restricted Units shall be converted to U.S. dollars on the Crediting Date (the first Bonus Payment Date during the Plan Year in which such Bonus is payable) at a rate equal to the exchange rate of such currency and U.S. dollars on such Crediting Date as reported in The Wall Street Journal in its issue following the Crediting Date. (c) BASE SALARY UNITS. Each Employee who is an Eligible Employee for any Plan Year beginning on or after August 1, 1999 may elect to have up to 50% of the amount of the base salary otherwise payable to the Eligible Employee on each payday during such year paid in the form of Restricted Units that will be credited to his or her Account hereunder and distributed in accordance with the provisions of this Plan, instead of being paid to the Eligible Employee in cash. If an Eligible Employee has so elected, the amount specified in such election shall be withheld from the payment of base salary otherwise required to be made to the Eligible Employee on each payday during such year, and the Eligible Employee's Account shall be credited on January 31 and on July 31 of such year, with a number of Restricted Units determined by dividing (i) the aggregate amount so withheld from the start of such year, in the case of the Restricted Units to be credited on January 31, or from January 31, in the case of the Restricted Units to be credited on July 31, by (ii) the Closing Price of a share of Common Stock on the applicable crediting date or, if such date is not a Trading Day, on the next following day that is a Trading Day. In the event that an Eligible Employee's base salary is payable in a unit of currency other than U.S. dollars, the aggregate amount withheld shall be converted to U.S. dollars on the January 31 or July 31 Crediting Date, as the case may be, at a rate equal to the exchange rate of such currency and U.S. dollars on such Crediting Date as reported in The Wall Street Journal in its issue following the Crediting Date. (d) CASH PAYMENT UNITS. Each Employee who is an Eligible Employee for any Plan Year beginning on or after August 1, 1999 may make a direct cash payment to the Corporation at least seven days prior to (i) the first Bonus Payment Date during such Plan Year and/or (ii) January 31 of such Plan Year. The Crediting Dates with respect to such direct cash payments shall be (i) the first Bonus Payment Date of the Plan Year with respect to cash payments made at least -6- seven days prior to such Bonus Payment Date and (ii) January 31 with respect to cash payments made at least seven days prior to that date. In consideration of any such cash payment, the Eligible Employee shall have his or her Account credited, on the relevant Crediting Date, with a number of Restricted Units determined by dividing (i) the amount of such cash payment by (ii) the Closing Price of a share of Common Stock on such Crediting Date or, if such date is not a Trading Day, on the next following day that is a Trading Day. In the event that an Eligible Employee's direct cash payment is made in a unit of currency other than U.S. dollars, the amount of such payment shall be converted to U.S. dollars on the relevant Crediting Date, at a rate equal to the exchange rate of such currency and U.S. dollars on such Crediting Date as reported in The Wall Street Journal in its issue following the Crediting Date. The aggregate amount of the direct cash payments that an Eligible Employee may make under this Section 5(d) during any Plan Year (the "Cash Purchase Year") shall not exceed the sum of (x) the amount by which 50% of the Eligible Employee's base salary for the Plan Year immediately preceding the Cash Purchase Year exceeds the portion thereof which the Eligible Employee has elected under Section 5(c) to have paid in the form of Restricted Units, plus (y) the amount by which the Bonus payable to the Eligible Employee during the Cash Purchase Year (based on results of operations for the immediately preceding Plan Year) exceeds the portion thereof which the Eligible Employee elected under Section 5(b) to have paid in the form of Restricted Units. (e) MATCHING UNITS. On each date on which any Restricted Units are credited to an Eligible Employee's Account pursuant to the provisions of paragraphs (b), (c) or (d) of this Section 5, there shall also be credited to the Eligible Employee's Account on that date a number of Matching Restricted Units equal to (i) 50% of the number of Base Salary Units credited on January 31, 2005 and August 1, 2005 and (ii) 100% of the number of Cash Payment Units purchased after September 10, 2004 and credited on January 31, 2005 and 100% of the number of Restricted Units of all kinds (other than Dividend Equivalent Units) credited after August 1, 2005. (f) DIVIDEND EQUIVALENTS. Until the Vesting Date for the Restricted Units that have been credited to a Participant's Account pursuant to paragraphs (a), (b), (c), (d) and (e) of this Section 5, additional Restricted Units shall be credited to the Participant's Account, with respect to the Restricted Units so credited, as of each Dividend Payment Date. The number of additional Restricted Units to be so credited shall be determined separately for each Initial Award Restricted Unit Subaccount, for each Purchased Restricted Unit Subaccount, and for each Matching Restricted Unit Subaccount, maintained for a Participant pursuant to Section 8. The number of additional Restricted Units to be credited to each such Subaccount shall be determined by first multiplying (A) the total number of Restricted Units standing to the Participant's credit in such Subaccount on the day immediately preceding such Dividend Payment Date (including all Dividend Equivalent Units credited to such Subaccount on all previous Dividend Payment Dates), by (B) the per-share dollar amount of the dividend paid on such Dividend Payment Date and then, dividing the resulting amount by the Closing Price of one share of Common Stock on such Dividend Payment Date. -7- (g) ELECTION PROCEDURES. Any election made by an Eligible Employee under paragraph (b) or (c) of this Section 5 shall be made in accordance with, and shall be subject to, the provisions set forth below.

The dollar amount or percentage so specified shall be at least equal to any minimum amount or percentage which the Committee in its discretion may have determined to be applicable to elections under Section 5(b) and/or Section 5(c) for the Plan Year.

Payment shall be made within 30 days after such termination date.

(iii) The Participant may select, as the Payment Date for such Units, (A)(1) the first Business Day of the third calendar year following the calendar year in which the Vesting Date for such Units occurs, or any later calendar month, or (2) in the case of any such Units that become vested on or after January 31, 2006, the first Business Day of any calendar year or month after the fifth anniversary of the Vesting Date for such Units; (B)(1) the first Business Day of the calendar year following the date on which the Participant's Termination of Employment occurs for any reason, or (2) in the case of any such Units that become vested on or after January 31, 2006, the later of (x) the first Business Day referred to in clause (B)(1) or (y) the first Business Day of the calendar month following the fifth anniversary of the Vesting Date for such Units; or (C) the earlier of (1) the first Business Day of any calendar year or month selected by the Participant which is a year or month permitted to be selected under clause (A) of this sentence, or (2) the first Business Day of the calendar year or month referred to in clause (B) of this sentence. -13- (iv) Any election made hereunder by the Participant shall be irrevocable. (v) As of the Vesting Date for any Restricted Units covered by a deferral election made by a Participant hereunder, the number of such Units shall be transferred from the Restricted Unit Subaccount or Matching Restricted Unit Subaccount in which such Units were recorded to the appropriate Deferred Vested Unit Subaccount established for the Participant under Section 8. (vi) Until payment has been made with respect to all of the Units in any Deferred Vested Unit Subaccount maintained for the Participant under Section 8, there shall be credited to each such Subaccount, as of each Dividend Payment Date, a number of additional Deferred Vested Units determined by first multiplying (A) the total number of Deferred Vested Units standing to the Participant's credit in such Subaccount on the day immediately preceding such Dividend Payment Date (including all Dividend Equivalent Units credited to such Subaccount on all previous Dividend Payment Dates), by (B) the per-share dollar amount of the dividend paid on such Dividend Payment Date and then, dividing the resulting amount by the Closing Price of one share of Common Stock on such Dividend Payment Date. (vii) Except as provided in subparagraph (viii) below, payment with respect to the Deferred Vested Units in any Deferred Vested Unit Subaccount maintained for the Participant shall be made on the Payment Date specified by the Participant in his or her deferral election with respect to such Units or, if applicable, on the Delayed Payment Date for such Units provided in paragraph (f)(iii) below. Payment with respect to the Deferred Vested Units payable on any Payment Date or Delayed Payment Date shall be made (A) by the issuance of one share of Common Stock for each whole Deferred Vested Unit payable on such Payment Date or Delayed Payment Date, and (B) by a cash payment for any fractional part of a Deferred Vested Unit payable on such Payment Date or Delayed Payment Date. The amount of such cash payment shall be determined by multiplying such fractional part by the Closing Price of a share of Common Stock on the first Trading Day preceding the date of payment. (viii) Notwithstanding any other provision in this Section 7 to the contrary, payment with respect to any part or all of any Deferred Vested Unit Subaccount maintained for a Participant may be made to the Participant on any date earlier than the Payment Date specified by the Participant in his deferral election for such Units if (A) the Participant requests such early payment and (B) the Committee, in its sole discretion, determines that such early payment is necessary to help the Participant meet an "unforeseeable emergency" within the meaning of Section 1.457-6(c)(2) of the federal income tax regulations or, in the case of any request for early payment made after January 1, 2005, within the meaning of section 409A(a)(2)(B)(ii)(I) of the Code. The amount that may be so paid may not exceed the amount necessary to meet such emergency or, for any early payment requested after January 1, 2005, the amount permitted to be paid under section 409A(a)(2)(B)(ii)(II) of the Code. -14- (e) LIMITATIONS ON DEFERRALS. A deferral election otherwise permitted to be made under paragraph (d) above shall be subject to the following limitations: (i) The Committee may deny any Participant the right to make such election if it determines, in its sole discretion, that such deferral election by the Participant might cause the Plan to fail to be treated as a plan of deferred compensation "for a select group of management or highly compensated employees" for purposes of ERISA. (ii) If a Change in Control should occur after the date on which the Participant's election form is filed with the Committee but before the date that otherwise would have been the Vesting Date under Section 6(a)(i) or (ii) for the Units designated in such form, the Participant's deferral election shall not be given effect, and payment with respect to such Units shall be made in accordance with the other applicable provisions of this Section 7. (iii) No deferral election shall be effective hereunder if, at any time during the 12-month period ending on the Vesting Date, the Participant received a hardship withdrawal under Section 7.2 of the Pall Corporation Profit-Sharing Plan. (iv) No amount may be deferred with respect to the Participant's Vested Units pursuant to a Participant's deferral election hereunder to the extent that any tax is required to be withheld with respect to such amount pursuant to applicable federal, state or local law. (f) DELAY IN TIME FOR PAYMENT. To the extent provided in subparagraph (i), (ii) or (iii) below, payment otherwise required to be made with respect to any of a Participant's Vested Units at the time specified in paragraph (a) above, and payment otherwise required to be made with respect to any of Participant's Deferred Vested Units on the Payment Date for such Units determined under clause (B)(2) or clauses (B)(2) and (C)(2) of paragraph (d)(iii) above, shall not be made at such times but shall be made, instead, at the times provided in subparagraph (i), (ii) or (iii) below. (i) Payment with respect to any of a Participant's Post-2004 Bonus and Base Salary Units that become vested pursuant to Section 6(a)(v) by reason of the occurrence of a Change in Control shall be made within 30 days after, (A) the earliest date on which such Units otherwise would become vested under Section 6(a) in the absence of the occurrence of a Change in Control, or (B), if earlier, the date of the Participant's Termination of Employment for any reason other than death or as a result of the Participant's having become Disabled; provided, however, that if the Participant was a Key Employee (as defined in subparagraph (iv) below) immediately prior to such Termination of Employment, payment pursuant to this clause (B) shall be made on the day that is 6 months after the date of such Termination of Employment or, if the Participant dies before that day, by no later than 7 Business Days after the Corporation receives written notice of the Participant's death. -15- (ii) In the case of a Participant whose Termination of Employment occurs after January 31, 2005 for any reason other than the Participant's death or as a result of the Participant having become Disabled, and who was a Key Employee immediately prior to his or her Termination of Employment, payment with respect to any of the Participant's Post-2004 Bonus and Base Salary Units that become vested pursuant to Section 6(b) or (c) by reason of the Participant's Termination of Employment shall be made at the times provided below: (A) Payment with respect to any such Units that become vested by reason of the Participant's Termination of Employment at any time during calendar year 2005 shall be made at the time specified in paragraph (a) above, provided that such payment is made on or prior to December 31, 2005. Such payment shall be treated as having been made to the Participant upon his or her termination of participation in the Plan, for purposes of Q & A 20 of IRS Notice 2005-1. (B) Payment with respect to any such Units that become vested by reason of the Participant's Termination of Employment at any time after December 31, 2005 (or which become vested by reason of the Participant's Termination of Employment before that date but payment with respect to which is not made to the Participant on or before that date) shall be made on the day which is 6 months after the date of the Participant's Termination of Employment or, if the Participant dies before such day, by no later than 7 Business Days after the Corporation receives written notice of the Participant's death. (iii) In any case where (A) any of a Participant's Deferred Vested Units that became vested on or after January 31, 2006 have a Payment Date determined by reference to the date of the Participant's Termination of Employment pursuant to clause (B)(2) or clauses (B)(2) and (C)(2) under paragraph (d)(iii) above, (B) the Payment Date for such Units, as so determined, is earlier than 6 months after the date of the Participant's Termination of Employment, (C) the Participant's Termination of Employment occurs for any reason other than death or as a result of the Participant having becoming Disabled, and (D) the Participant is a Key Employee immediately prior to the Participant's Termination of Employment, payment with respect to such Deferred Vested Units shall be made on the day which is 6 months after the date of the Participant's Termination of Employment or, if the Participant dies before such day, by no later than 7 business days after the Corporation receives written notice of the Participant's death. -16- (iv) For purposes of this paragraph (f), the term "Key Employee" shall mean a Participant who, as of any date of reference, is a "specified employee" within the meaning of section 409A(a)(2)(B)(i) of the Code. (v) The provisions of subparagraph (i) and (ii) above shall not apply to the payment required to be made under this Section 7 with respect to a Participant's Units that become vested upon the occurrence of a Change in Control, or to the payment required to be made under this Section 7 with respect to a Participant's Units that become vested upon the Participant's Termination of Employment, if in either case the Participant would not be required to include such payment in his or her gross income for federal income tax purposes if such payment were made to the Participant at the time specified in paragraph (a) above. The provisions of subparagraph (iii) above shall not apply to the payment required to be made under this Section 7 with respect to any of a Participant's Deferred Vested Units if the Participant would not be required to include such payment in his or her gross income for federal income tax purposes if such payment were made to the Participant on the Payment Date for such Units determined under paragraph (d)(iii) above. (vi) If payment with respect to any of a Participant's Post-2004 Bonus and Base Salary Units is delayed pursuant to subparagraph (i) or subparagraph (ii)(B) above, Dividend Equivalent Units shall be credited to the Participant's Account with respect to such Units, in the same manner as provided in paragraph (d)(vi) above, on each Dividend Payment Date occurring during the period from the Vesting Date for such Units to the Delayed Payment Date for such Units. 8. ACCOUNTS. There shall be established on the books and records of the Corporation, for bookkeeping purposes only, a separate Account for each Participant, to reflect the Participant's interest under the Plan. Within each Account so established for each Participant there shall be established and maintained the following Subaccounts: an "Initial Award Restricted Unit Subaccount" to reflect all Restricted Units to be credited to the Participant's Account on any Crediting Date pursuant to Section 5(a); a "Purchased Restricted Unit Subaccount" to reflect all Restricted Units to be credited to the Participant's account on any Crediting Date pursuant to Section 5(b), (c) or (d); a "Matching Restricted Unit Subaccount" to reflect all Matching Restricted Units to be credited to the Participant's Account on any Crediting Date pursuant to Section 5(e); and a "Deferred Vested Unit Subaccount" to reflect all Vested Units with respect to which a Participant has elected to defer payment, and for which the Participant has selected the same Payment Date, pursuant to Section 7(d). -17- A Participant's Account and Subaccounts shall be adjusted from time to time to reflect all Dividend Equivalent Units to be credited thereto pursuant to Section 5(f) and Section 7(d)(vi), all payments made with respect to the Units reflected therein pursuant to Section 7, and, in the case of any Initial Award Restricted Unit Subaccount, Purchased Restricted Unit Subaccount or Matching Restricted Unit Subaccount maintained for a Participant, any forfeitures of Units reflected therein pursuant to Section 6. A Participant's interest in any Deferred Vested Unit Subaccount maintained for the Participant shall be fully vested and nonforfeitable at all times. 9. CERTAIN ADJUSTMENTS TO PLAN SHARES. In the event of any change in the shares of Common Stock by reason of any stock dividend, stock split, recapitalization, reorganization, merger, consolidation, split-up, combination or exchange of shares, or any rights offering to purchase shares of Common Stock at a price substantially below fair market value, or any similar change affecting the shares of Common Stock, the number and kind of shares represented by Units credited to Participants' Accounts shall be appropriately adjusted consistent with such change in such manner as the Compensation Committee, in its sole discretion, may deem equitable to prevent substantial dilution or enlargement of the rights granted to, or available for, the Participants hereunder. The Committee shall give notice to each Participant of any adjustment made pursuant to this Section and, upon such notice, such adjustment shall be effective and binding for all purposes. 10. LISTING AND QUALIFICATION OF COMMON STOCK. The Corporation, in its discretion, may postpone the issuance, delivery, or distribution of shares of Common Stock with respect to any Vested Units until completion of such stock exchange listing or other qualification of such shares under any state or federal law, rule or regulation as the Corporation may consider appropriate, and may require any Participant or Beneficiary to make such representations and furnish such information as it may consider appropriate in connection with the issuance or delivery of the shares in compliance with applicable laws, rules and regulations. 11. TAXES. The Corporation or any of its Affiliated Companies may make such provisions and take such steps as it may deem necessary or appropriate for the withholding of all federal, state and local taxes required by law to be withheld with respect to any payments to be made under the Plan including, but not limited to (i) deducting the amount so required to be withheld from any other amount then or thereafter payable to a Participant or Beneficiary, and/or (ii) requiring a Participant or Beneficiary to pay to the Corporation or any of its Affiliated Companies the amount so required to be withheld as a condition of the issuance, delivery, or distribution of any shares of Common Stock. With the approval of the Compensation Committee, the Committee may permit such amount to be paid in shares of Common Stock previously owned by the Participant, or a portion of the shares of Common Stock that otherwise would be distributed to such Participant in respect to his or her Vested Units, or a combination of cash and shares of Common Shares. -18- 12. DESIGNATION AND CHANGE OF BENEFICIARY. Each Participant shall file with the Committee a written designation of one or more persons as the Beneficiary who shall be entitled to receive any amount, or any shares of Common Stock, payable under the Plan upon his or her death. A Participant may, from time to time, revoke or change his or her Beneficiary designation without the consent of any previously designated Beneficiary by filing a new designation with the Committee. The last such designation received by the Committee shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant's death, and in no event shall it be effective as of a date prior to such receipt. If at the date of a Participant's death, there is no designation of a Beneficiary in effect for the Participant pursuant to the provisions of this Section 12, or if no Beneficiary designated by the Participant in accordance with the provisions hereof survives to receive any amount, or any shares of Common Stock, payable under the Plan by reason of the Participant's death, the Participant's estate shall be treated as the Participant's Beneficiary for purposes of the Plan. 13. RIGHTS OF PARTICIPANTS. A Participant's rights and interests under the Plan shall be subject to the following provisions: (a) A Participant shall have the status of a general unsecured creditor of the Corporation with respect to his or her right to receive any payment under the Plan. The Plan shall constitute a mere promise by the Corporation or the applicable Affiliated Company to make payments in the future of the benefits provided for herein. It is intended that the arrangements reflected in the Plan be treated as unfunded for tax purposes, as well as for purposes of any applicable provisions of Title I of ERISA. (b) A Participant's rights to payments under the Plan shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by creditors of the Participant or his or her Beneficiary. (c) Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right to be retained in the employment of the Corporation or any of its Affiliated Companies. (d) No Participant shall have the right, by virtue of having been selected as an Eligible Employee with respect to any Plan Year, to be automatically treated as an Eligible Employee with respect to any subsequent Plan Year. -19- (e) No Restricted Units credited to a Participant's Account, and no payments made with respect to such Units upon or after they become vested, shall be considered as compensation under any employee benefit plan of the Corporation or any of its Affiliated Companies, except as specifically provided in any such plan or as otherwise determined by the Board of Directors. 14. ADMINISTRATION. The Plan shall be administered by the Committee. A majority of the members of the Committee shall constitute a quorum. The Committee may act at a meeting, including a telephone meeting, by action of a majority of the members present, or without a meeting by unanimous written consent. In addition to the responsibilities and powers assigned to the Committee elsewhere in the Plan, the Committee shall have the authority, in its discretion, to establish from time to time guidelines or regulations for the administration of the Plan, interpret the Plan, and make all determinations considered necessary or advisable for the administration of the Plan; provided, however, that any questions as to the rights under the Plan of any person who is an Elected Officer under Section 4.01(a) of the By-Laws of the Corporation, as amended on July 15, 2003 or thereafter, shall be determined by the Compensation Committee instead of by the Committee. The Committee may delegate any ministerial or nondiscretionary function pertaining to the administration of the Plan to any one or more officers of the Corporation. All decisions, actions or interpretations of the Committee or the Compensation Committee under the Plan shall be final, conclusive and binding upon all parties. Notwithstanding the foregoing, any determination made by the Committee or the Compensation Committee after the occurrence of a Change in Control that denies in whole or in part any claim made by any individual for benefits under the Plan shall be subject to judicial review, under a "de novo", rather than a deferential standard. 15. AMENDMENT OR TERMINATION. The Board of Directors may, with prospective or retroactive effect, amend, suspend or terminate the Plan or any portion thereof at any time; provided, however, that (a) no amendment, suspension or termination of the Plan shall adversely affect the rights of any Participant with respect to any Units previously credited to the Participant's Account, without his or her written consent and (b) no amendment which constitutes a "material revision" of the Plan, as the term material revision is defined in the applicable rules of the New York Stock Exchange, shall be effective unless approved by the shareholders in the manner required by such rules and by applicable law. 16. SUCCESSOR CORPORATION. The obligations of the Corporation under the Plan shall be binding upon any successor corporation or organization resulting from the merger, consolidation or other reorganization of the Corporation, or upon any successor corporation or organization succeeding to substantially all of the assets and business of the Corporation. The Corporation agrees that it will make appropriate provision for the preservation of Participants' rights under the Plan in any agreement or plan which it may enter into or adopt to effect any such merger, consolidation, reorganization or transfer of assets. -20- 17. GOVERNING LAW. The Plan shall be governed by and construed in accordance with the laws of the State of New York. 18. EFFECTIVE DATE. The Plan was adopted effective as of June 29, 1999 by the Board of Directors, acting by the Compensation Committee, and approved by the shareholders of the Corporation by a majority of the votes cast in person or by proxy at the 1999 annual meeting of the Corporation's shareholders. The effectiveness of the amendment to Section 5(e) made by the Compensation Committee on September 10, 2004 was conditioned on approval of the Pall Corporation 2005 Stock Compensation Plan by shareholders at the 2004 Annual Meeting, which approval was granted at the Annual Meeting on November 17, 2004. [As adopted by the Compensation Committee of the Board of Directors on June 29, 1999, amended by that Committee by Consent dated October 1, 1999, approved by shareholders at the annual meeting on November 17, 1999 and further amended by the Compensation Committee by Consents dated January 19, 2000 and March 28, 2001 and at a meeting held July 16, 2002, by the Executive Committee by Consent dated January 30, 2003 and by the Compensation Committee at meeting held October 16, 2003, the last-mentioned amendment having been approved by shareholders at the Annual Meeting on November 19, 2003, and further amended by the Compensation Committee at meetings held January 21, 2004, September 10, 2004, January 19, 2005 and July 19, 2005.] -21-
