                              GELMAN SCIENCES INC.


                         EXECUTIVE STOCK OWNERSHIP PLAN




1.    PURPOSE

      The Gelman Sciences Inc. Executive Stock Ownership Plan (the "Plan") is
      intended to foster and promote the long-term growth and performance of
      Gelman Sciences Inc. (the "Company") by requiring and enabling the
      acquisition of a significant personal equity interest in the Company by
      those Company executives upon whose judgment and efforts the Company is
      largely dependent for the successful conduct of its business.  As equity
      holders, Company executives will participate in future appreciation in
      the share value of the Company's stock, thus further aligning their
      interests with the interests of other shareholders of the Company, with
      the goal of maximizing return on shareholder investment.  The opportunity
      to participate in Company stock appreciation should enable the Company to
      attract and retain key executives critical to the long-term success of
      the Company.  The Plan was adopted by the Company's Board of Directors on
      September 20, 1995, with an effective date of August 1, 1995, subject to
      shareholder approval and ratification.

2.    BACKGROUND

      The Plan is a feature of the Company's Executive Compensation Plan, also
      adopted by the Board on September 20, 1995, with an effective date of
      August 1, 1995.  Pursuant to the Executive Compensation Plan, the Board
      or its Compensation Committee (the "Committee") will make an annual
      determination as to the dollar amount of a bonus pool to be allocated
      among the Company's executive officers and other employees.  It is the
      goal of the Company that each executive officer acquire and retain of no
      fewer than that number of shares of the Company's common stock ("Common
      Stock") with a value equal to fifty percent (50%) of such officer's
      annual base salary (the "Equity Value Requirement"), as adjusted from
      time to time.  Consistent with that goal, the annual bonus paid to each
      executive officer will be paid in the form of a specified amount of
      Common Stock, and the remainder of the bonus will be paid in cash.  As of
      each July 31st during the period in which the Plan is in effect, the
      value of each executive officer's beneficial ownership of Common Stock
      will be calculated, using the closing price on the principal stock
      exchange on which the Common Stock is then traded for such day, or, if it
      is not a trading day, then on the last trading day immediately preceding
      such day.  If the Equity Value Requirement is not met by an executive
      officer as of any July 31st, the annual bonus received by that officer
      for that year will have a stock component.  The size of the stock
      component will be sufficient to satisfy the




                                       1

      Equity Value Requirement, subject to the limitation that the value of the
      stock component paid to an executive officer with respect to any year
      will not exceed the lesser of thirty percent (30%) of that officer's
      annual bonus or ten percent (10%) of such officer's annual base salary
      for that year.

3.    ADMINISTRATION

      The Plan will be administered by a committee ("Committee"), comprised of
      three or more disinterested members of the Board, none of whom will be an
      employee of the Company or a participant in the Plan.  A majority of
      Committee members will constitute a quorum, and the action of a majority
      of the members of the Committee present at any meeting at which a quorum
      is present, or the unanimous written action of the Committee, will be
      considered the action of the Committee.  Except for the terms and
      conditions explicitly set forth in the Plan, the Committee will have the
      authority, in its discretion, to determine all matters relating to awards
      under the Plan.  All decisions made by the Committee pursuant to the
      provisions of the Plan and related orders or resolutions of the Board
      shall be final and conclusive.

4.    PARTICIPANTS

      The Chief Executive Officer, the Chief Operating Officer and all other
      executive officers of the Company will participate in the Plan.

5.    STOCK SUBJECT TO THE PLAN; ADJUSTMENTS

      The stock awarded under the Plan will be shares of Common Stock and may
      be authorized and unissued shares or shares now held or subsequently
      acquired by the Company or a combination thereof, as the Board may from
      time to time determine.  The aggregate number of shares to be awarded
      under the Plan will not exceed 100,000, subject to adjustment for any
      increase or decrease in the number of issued shares of Common Stock
      resulting from any reorganization, capitalization, stock split, stock
      dividend or similar corporate transaction.

6.    STOCK AWARDS

      Stock awards under the Plan will be determined pursuant to the provisions
      of Section 2, above.

7.    WITHHOLDING TAXES

      The Company will have the right to deduct from any award made under the
      Plan an amount sufficient to cover withholding required by law for any
      federal, state or local taxes or to take such other action as may be
      necessary to satisfy any such withholding obligations, including the
      withholding from any other cash amounts

      due or to become due from the Company to the participant an amount equal
      to such taxes.

8.    TERM OF THE PLAN

      The Plan is effective as of August 1, 1995, and shall remain in full
      force and effect until all the Common Stock subject to it shall have been
      issued pursuant to the provisions hereof, unless sooner terminated by the
      Board.

9.    PLAN AMENDMENT; TERMINATION

      This Plan is subject to initial ratification and approval by the
      Company's shareholders, but may be terminated or suspended or amended
      thereafter from time to time by the Committee or the Board; provided,
      however, no amendment by the Committee or the Board shall (a) increase
      the maximum number of shares of Common Stock that may be issued under the
      Plan, subject to adjustments pursuant to Section 5 above, (b) change the
      designation in Section 4 of the Plan participants or (c) cause Rule 16b-3
      (or any successor rule) promulgated by the Securities and Exchange
      Commission (the "Commission") under the Securities Exchange Act of 1934
      (the "Exchange Act") to cease to be applicable to this Plan, without
      further approval of the shareholders of the Company. The Plan may not be
      amended more than once every six months, other than to comport with
      changes in the Internal Revenue Code, the Employee Retirement Income
      Security Act, or the rules thereunder, or rules promulgated by the
      Commission.

10.   INDEMNIFICATION

      Each person who is or shall have been a member of the Committee shall be
      indemnified and held harmless by the Company against and from any loss,
      cost, liability, or expense that may be imposed upon or reasonably
      incurred by him or her in connection with or resulting from any claim,
      action, suit, or proceeding to which he or she may be a party or in which
      he or she may be involved by reason of any action taken or failure to act
      under the Plan and against and from any and all amounts paid by him or
      her in settlement thereof, with the Company's approval, or paid by him or
      her in satisfaction of any judgment in any such action, suit, or
      proceeding against him or her, provided he or she shall give the Company
      an opportunity, at its own expense, to handle and defend the same before
      he or she undertakes to handle and defend it on his own behalf.  The
      foregoing right of indemnification shall not be exclusive of any other
      rights of indemnification to which any such person may be entitled under
      the Company's Articles of Incorporation or By-laws, as a matter of law,
      or otherwise, or any power that the Company may have to indemnify or hold
      such person harmless.

11.   REQUIREMENTS OF LAW

      The issuance of Common Stock under the Plan will be subject to all
      applicable laws, rules, and regulations, and to such approvals by any
      governmental agencies or national securities exchanges as may be
      required.  The Plan, and all agreements hereunder, shall be construed in
      accordance with and be governed by the laws of the State of Michigan.

      It is the intention of the Company that the Plan will comply in all
      respects with Rule 16b-3, including any successor provision to Rule
      16b-3, and, if any Plan provision is later found not to be in compliance
      with Section 16 of the Exchange Act, that provision will be deemed null
      and void, and in all events the Plan will be construed in favor of its
      meeting the requirements of Rule 16b-3.  Specifically, the Plan is
      intended to comply with and be subject to Rule 16b-3 as in effect prior
      to May 1, 1991.  The Committee may at any time elect that this Plan shall
      be subject to a successor to this rule and, without shareholder approval,
      make any and all amendments to this Plan that are necessary to comply
      with the provisions of the Rule as then in effect or make any other
      amendments that do not require shareholder approval under applicable
      rules and regulations then in effect.  Notwithstanding anything in the
      Plan to the contrary, the Board, in its absolute discretion, may
      bifurcate the Plan so as to restrict, limit or condition the use of any
      provision of the Plan to participants who are subject to Section 16 of
      the Exchange Act without so restricting, limiting or conditioning the
      Plan with respect to other participants, if any.
