                                PALL CORPORATION

                         MANAGEMENT STOCK PURCHASE PLAN

                                      -----


1.       Purpose.

         This document sets forth the Pall Corporation Management Stock Purchase
Plan as adopted effective June 29, 1999 and amended effective October 1, 1999
and January 19, 2000.

         The purpose of the Plan is to encourage key employees of the
Corporation and its Affiliated Companies to increase their ownership of shares
of the Corporation's Common Stock by providing such employees with an
opportunity to elect to have portions of their total annual compensation paid in
the form of Restricted Units, and to have additional matching Restricted Units
credited with respect thereto.

         The Plan also provides certain employees with an opportunity to elect
to defer payment with respect to the Restricted Units credited to them that
become vested. With respect to these provisions, the Plan is intended to
constitute an unfunded plan of deferred compensation for "a select group of
management or highly compensated employees" within the meaning of Sections
201(2), 301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act
of 1974, as amended ("ERISA").

4.       Eligibility.

         An Employee shall be eligible to be credited with Restricted Units

         Upon the recommendation of the CEO, the Compensation Committee may
select as an Eligible Employee for any Plan Year any Employee who is expected to
make significant contributions during the course of such year to the success of
the Corporation and its Affiliated Companies and to the growth of their
businesses.

         Any person who has been selected as an Eligible Employee for any Plan
Year shall continue to be an Eligible Employee in the Plan for each subsequent
Plan Year during the period of his or her employment, subject, however, to the
Compensation Committee's right to terminate such individual's eligibility
effective beginning as of the first base salary payment date or, if earlier, the
first Bonus Payment Date occurring after the date on which the Compensation
Committee makes its determination to terminate such individual's eligibility.

5.       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. Each Employee who is an Eligible Employee for
the Plan Year that begins on August 1, 1999 shall be credited as of such date
with such number of Restricted Units as the Compensation Committee in its sole
discretion may determine for such Employee. To the extent that the Compensation
Committee in its sole discretion so determines, any Employee who is designated
as an Eligible Employee 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.

         (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

<PAGE>

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
seven days prior to such Bonus Payment Date and (ii) January 31 with respect to

<PAGE>

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 shall not exceed
the sum of (x) the amount by which 50% of the Eligible Employee's base salary
for such 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 such
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 Restricted Units credited on such date,
in the case of Restricted Units credited during the Plan Year beginning on
August 1, 1999, and (ii) 33_% of the number of Restricted Units credited on such
date, in the case of Restricted Units credited during each Plan Year beginning
on or after August 1, 2000.

         (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.

         (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.

                  (i) any such election shall be made in writing, on a form

         and filed by the Eligible Employee with the Committee.

                  (ii) An election under Section 5(b) with respect to the Bonus
         payable to an Eligible Employee during the Plan Year beginning on
         August 1, 1999 shall be made by no later than July 23, 1999. An
         election under Section 5(b) with respect to the Bonus payable to an
         Eligible Employee during any Plan Year beginning on or after August 1,
         2000 shall be made by no later than April 30 of the immediately
         preceding Plan Year. An election under Section 5(c) with respect to the
         base salary payable to an Eligible Employee during any Plan Year shall
         be made on or prior to the last Business Day preceding the start of
         such Plan Year. Notwithstanding the foregoing, any Employee who is
         hired after the start of a Plan Year but who is designated under
         Section 4 as an Eligible Employee for such year may make election under
         Section 5(c) with respect to his or her base salary for such year at
         any time during the 30-day period commencing on his or her date of
         hire; provided, however, that any election so made shall be effective
         only with respect to base salary payable to the Eligible Employee for
         periods of service beginning after the date on which he or she files
         such election with the Committee.

                  (iii) In his or her election form, the Eligible Employee shall
         specify, by dollar amount (which shall be an even multiple of $100) or
         by percentage (which shall be an even multiple of 1%), the portion of
         his or her Bonus and/or base salary that the Eligible Employee wishes
         to have paid in the form of Restricted Units credited to his or her
         Account, instead of in cash. 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.

                  (iv) Any election made under Section 5(b) or (c) for any Plan
         Year shall be irrevocable.

         (h) Other Election Rules. Elections made under Section 5(b) or (c)
shall be subject to the following rules:

                  (i) If an Eligible Employee who has made an election under
         Section 5(b) with respect to the Bonus payable to the Eligible Employee
         during any Plan Year terminates employment with the Company and all of
         its Affiliated Companies for any reason prior to any Bonus Payment Date
<PAGE>

         for such Bonus but is nevertheless entitled to receive a Bonus payment
         on such date, the portion of such payment that is otherwise required to
         be paid by means of the crediting of Restricted Units to the Eligible
         Employee's Account pursuant to his or her election under Section 5(b)
         shall not be paid in such form, but shall be paid instead in the form
         of a single lump sum cash payment. Such payment shall be made as soon
         as practicable after such Bonus Payment Date.

                  (ii) If an Eligible Employee who has made an election under
         Section 5(c) with respect to the base salary payable to the Eligible
         Employee during any Plan Year terminates employment with the Company
         and all of its Affiliated Companies for any reason prior to any date on
         which Restricted Units are to be credited to his or her Account with
         respect to amounts withheld from his or her base salary pursuant to
         such election, no Restricted Units shall be so credited on such date
         but instead, the aggregate amount so withheld as of the date of the
         Eligible Employee's termination of employment shall be paid to the
         Eligible Employee, without interest thereon, in a single lump sum cash
         payment. Payment shall be made on such termination date, or as soon
         thereafter as is practicable.

                  (iii) Any election made by an Eligible Employee under Section
         5(b) or (c) shall not be given effect if, at any time during the
         12-month period ending on the date as of which any Restricted Units are
         otherwise required to be credited to his or her Account pursuant to
         such election, the Eligible Employee received a hardship withdrawal
         under Section 7.2 of the Pall Corporation Profit-Sharing Plan.

Reward Restricted Unit Subaccount, Purchased Restricted Unit Subaccount or
Matching Restricted Unit Subaccount maintained for the Participant under Section
8 and prior to the occurrence of a Change in Control, as of the date of such
termination of the Participant's employment

                  (i) all Units in any such Purchased Restricted Unit Subaccount
         (including all such Units that are Dividend Equivalent Units), shall

         shall have no further rights with respect thereto.

         For purposes of the foregoing, the "Earned Portion" of the Units in any
Initial Award Restricted Unit Subaccount and in any Matching Restricted Unit

death, to his or her Beneficiary, as soon as practicable after the Vesting Date
for such Units, except as otherwise provided in paragraph (d) below.

         (b) Form of Payment. Except as provided in paragraph (c) below, payment
to be made in accordance with paragraph (a) above with respect to all Restricted
Units that have become vested on any Vesting Date shall be made in the form of a
single lump sum payment consisting of (i) a number of shares of Common Stock
equal to the total number of whole Restricted Units that have become vested on
such Vesting Date, and (ii) a cash payment for any fractional part of a
Restricted Unit that has become vested on such Vesting 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.

         (c) Payment on Termination. Payment to be made in accordance with
paragraph (a) above with respect to all Restricted Units that have become vested
pursuant to Section 6(c)(ii) on any Vesting Date shall be made by the issuance
of a number of shares of Common Stock determined by dividing the lesser of (x)
the aggregate value of such Units determined by multiplying the number of such
Units by the Closing Price of a share of Common Stock on the date or dates as of
which such Units were credited to the Participant's Account, or (y) the
aggregate value of such Units determined by multiplying the number of such Units
by the Closing Price of a share of Common Stock on such Vesting Date, by (z) the
Closing Price of a share of Common Stock on such Vesting Date. If such Vesting
Date was not a Trading Day, the Closing Price of a share of Common Stock on the
first Trading Day following such Vesting Date shall be used for purposes of the
preceding sentence. If the number of shares of Common Stock determined in
accordance with the provisions of the second preceding sentence includes a
fractional part of a share, payment with respect to such fractional part shall
be made in cash, in an amount 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.

         (d) Deferred Payment. Subject to the provisions of paragraph (e) below,
payment with respect to part or all of a Participant's Restricted Units that
become vested on any Vesting Date pursuant to Section 6(a)(i) shall be deferred,
and shall be made at the time and in the manner hereinafter set forth, if the
Participant so elects in accordance with the following provisions:

                  (i) An election by the Participant hereunder with respect to
         any Restricted Units that become vested on any Vesting Date shall be
         made in writing, on a form furnished to the Participant for such
         purpose by the Committee. The form shall be filed with the Committee at
         least one year prior to such Vesting Date.

                  (ii) In the Participant's election form, the Participant shall
         specify the number of such Restricted Units with respect to which the
         Participant wishes to defer payment, and the date on which payment with
         respect to such Units shall be made (the "Payment Date").

                  (iii) The Participant may select, as the Payment Date for such
         Units (A) the first Business Day of the calendar year following the
         date of termination of his or her employment with the Corporation or
         any of its Affiliated Companies for any reason, or (B) the first
         Business Day of any earlier calendar month but no earlier than the
         first Business Day of the third calendar year following the calendar
         year in which the Vesting Date for such Units occurs.

                  (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.

<PAGE>
                  (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. Payment with respect to the Deferred Vested
         Units payable on any 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, and (B) by a cash payment for any fractional part
         of a Deferred Vested Unit payable on such 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 1.457-2(h)(4) of the federal income tax regulations.
         The amount that may be so paid may not exceed the amount necessary to
         meet such emergency.

         (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) 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.

<PAGE>

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).

         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.

<PAGE>

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.

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.

<PAGE>

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.

         (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 June 29, 1999 or

<PAGE>

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 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.

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.

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, subject, however, to approval
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.
Restricted Units may be credited to the Accounts of Eligible Employees as
provided herein prior to such shareholder approval, subject to such approval
being obtained at such meeting.

<PAGE>

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 Consent dated January 19, 2000.
