             NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS


GENERAL

  In the opinion of the Company, the accompanying unaudited consolidated
financial statements contain all adjustments (which are of a normal recurring
nature) necessary to present fairly the financial position of Gelman Sciences
Inc. and subsidiaries as of January 31, 1995, and the results of their
operations and cash flows for the three months  and six months ended January
31, 1995 and 1994.  These financial statements should be read in conjunction
with the financial statements and notes set forth in the Company's Annual
Report and Form 10-K for the year ended July 31, 1994.  The results of
operations for the three months and six months ended January 31, 1995 and 1994
are not necessarily indicative of the results of the full year.

PUBLIC OFFERING

  On January 27, 1995 the Company filed a registration statement with the
Securities and Exchange Commission to sell 1,000,000 shares of common stock
in an underwritten public offering. The Company has granted the underwriters an 
option for 30 days to purchase up to an additional 150,000 shares of common 
stock solely to cover overallotment.

  The net proceeds from the sale of common stock will be used to repay a term
note payable to NBD Bank N.A. and to reduce outstanding indebtedness under the
Company's Credit Agreement.

POLLUTION RELATED MATTERS

     The Company has settled several lawsuits related to groundwater
contamination and has begun remediation activities. The remediation plan
requires the Company to treat the groundwater to the extent necessary to reduce
the contaminants to a defined level. Management estimates that remediation will
take eight years.  Total costs to the Company of pollution-related activities 
will be dependent upon the efficacy and duration of the remediation plan and
obtaining a cost-free repository for treated groundwater. The ultimate costs
to be incurred could exceed the amount provided of $1.1 million at January 31,
1995. However, it is the opinion of management that these additional costs, if
any, will not have a material adverse effect on the Company's operations because
the cash outflows would be spread over many future years.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
        RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

Comparison of Six Months ended January 31, 1995 and 1994

        Net sales for the six months ended January 31, 1995 increased $2.6
million or 5.7% to $48.2 million as compared to net sales of $45.6 million for
the six months ended January 31, 1994. Net sales for the six months ended
January 31, 1994 included (a) non-recurring sales of $3.0 million related to
the Company's Australian non-core product lines that have been divested and
(b) a special shipment of $800,000 of roll stock membrane to a single      
customer.  This customer has placed its annual order this year; however, the
shipment dates are spread over the next twelve months.  Sales in the first
half of fiscal 1995 were favorably affected by the weakened U.S. dollar,
which increased reported sales by $798,000. The Company's sales growth,
adjusted for these items, was 13.4%.

        Sales to customers in North, Central and South America increased 10.8%
over the same period of the prior fiscal year primarily due to a 31.6% increase
in sales of medical devices.  Sales to customers in Europe increased 17.0%
mainly due to increases in sales of process filtration products in Italy and
France.  Sales to customers in the Asia/Pacific region declined 28.0% as a 
result of the divestiture of the Australian non-core product lines. Without the 
effect of these sales, Asia/Pacific sales would have increased 22.5%, primarily
attributable to increases in sales of process filtration products in Japan and 
Korea. Worldwide sales of laboratory products, medical devices and process
filtration products increased 11.1%, 23.6% and 19.7%, respectively.  Worldwide
sales of microporous membranes decreased 8.2% as a result of the special 
shipment to a single customer in the first half of fiscal 1994.  Without the 
effect of this shipment, sales of microporous membranes would have increased 
14.7%.

        Gross profit increased $2.1 million or 9.1% to $24.6 million in the six
months ended January 31, 1995, as compared to $22.5 million in the six months
ended January 31, 1994.  As a percentage of net sales, gross profit increased
to 51.1% from 49.5%.  The improvement in gross profit is primarily
attributable to the divestiture of the lower margin non-core product lines and
improved operating efficiencies, which was partially offset by a less favorable
product mix due to lower membrane sales as a percentage of sales.

        Selling and administrative expenses increased $1.0 million or 6.3% to
$17.3 million in the six months ended January 31, 1995, compared to $16.3
million in the six months ended January 31, 1994.  The increase in selling and
administrative expenses was primarily due to efforts to implement the Company's
growth strategy, particularly in the international markets.





                                      -7-
<PAGE>   8
        
        Research and development expenses increased to $2.6 million in the six
months ended January 31, 1995 as compared to $2.3 million in the six months
ended January 31, 1994, or 12.8%.  As a percentage of net sales, these expenses
were 5.4% compared to 5.1%.  The higher research and development spending is 
a result of an increased effort to develop and modify products to meet 
customer requirements.

        The effective tax rate for each of the six months ended January 31,1995
and 1994 was 36.2%.

        Net earnings increased $495,000 or 24.8% to $2.5 million or $.38 per
share for the six months ended January 31, 1995, compared to $2.0 million or
$.32 per share for the six months ended January 31, 1994.  As a percentage of
sales, net earnings were 5.2% compared to 4.4% .

Comparison of Three Months ended January 31, 1995 and 1994

        Net sales for the second quarter ended January 31, 1995 increased by 
3.2% to $24.0 million as compared to $23.3 million for the second quarter of 
fiscal 1994. The second quarter sales for fiscal 1994 were affected by the two
items discussed under the six month sales comparison in the amount of $2.3 
million.  The second quarter fiscal 1995 sales were favorably affected by the 
weakened U.S. dollar, which increased reported sales by $474,000. The Company's
sales growth for the second quarter of fiscal 1995 versus the same period last
fiscal year, adjusted for the two items mentioned and the fluctuation in foreign
currency, was 12.3%.
        
        Worldwide sales of laboratory products, medical devices and process
filtration products increased 12.9%, 17.6% and 22.2%, respectively, as compared
to the second quarter of fiscal 1994.  The sales growth in these markets is
primarily attributable to a more intensive selling and marketing program,
especially its focus on sales outside the United States.  Membrane sales
decreased 21.8% because of the large shipment mentioned under the six month
comparison. Without this shipment, microporous membrane sales increased 12.1%
as compared to the second quarter of fiscal 1994.
        
        Net earnings for the second quarter ended January 31, 1995 were $1.3
million as compared to $1.1 million for the second quarter ended January 31,
1994. The second quarter of fiscal 1994 was favorably affected by the large     
shipment of roll stock membrane which increased earnings by $260,000. Without
this transaction, net earnings in the second quarter of fiscal 1995 would have
increased 50.5%. This transaction favorably impacted the gross profit in the
second quarter of fiscal year 1994 by 0.5%. Therefore, on a comparable
basis, gross profit as a percentage of sales increased from 49.5% to 51.9% for
the second quarter of fiscal 1995.

LIQUIDITY AND CAPITAL RESOURCES

  The Company generated cash from operations in the amount of $2.2 million and
increased borrowings by $1.2 million for the six months ended January 31, 1995.
The funds were used for capital expenditures of $3.2 million and to finance     
trade receivables attributable to higher sales in the last month of the second
quarter, which is a seasonal pattern. Working capital was $23.9 million and
$23.4 million at January 31, 1995 and July 31, 1994, respectively. The working
capital at January 31, 1995 includes the classification of a $3.5 million term
note due December 31, 1995 as a current liability. At January 31, 1995, the
Company's unused portion of its Credit Agreement was $7.5 million.

  On January 27, 1995, the Company filed a Registration Statement with the
Securities and Exchange Commission to sell 1,000,000 shares of common stock in
an underwritten public offering. The Company granted the underwriters an option
for 30 days to purchase up to an additional 150,000 shares of common stock
solely to cover overallotment. The net proceeds from the sale will be used to
repay the term note and to reduce outstanding indebtedness under the Company's
Credit Agreement. The proceeds should be received at the end of March.

                          PART II.  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

  The Company is involved in various legal actions in the normal course of
business.  In addition, the Company is currently a party to various legal
actions arising under statutes regulating the discharge of materials into or
otherwise protecting the environment.  These have been described in the
Company's 1994 Annual Report, in Item 1. "Environmental Regulations" and Item
3. "Legal Proceedings" of the Company's Form 10-K for the year ended July 31,   
1994, and in Item 1. "Legal Proceedings in Part II of the Company's Form 10-Q
for the quarter ended October 31, 1994.  The following sets forth these
environmental matters to the extent any material developments have occurred
since the filing of the Company's Form 10-Q for the quarter ended October 31,
1994.

  Campbell, et al. v. Gelman Sciences Inc. (Circuit Court for Washtenaw
County, Michigan, Case No. 91-41524-CE).  On July 30, 1991, a complaint was     
filed against the Company by five individuals residing in the Westover
residential subdivision located near the main facility of the Company for
damages for anticipated expenses for future medical monitoring asserted to be
necessary as a result of exposure to air and groundwater allegedly
contaminated by the Company.  On August 26, 1991, the Company filed its answer,
denying liability and asking the Court to dismiss this lawsuit.  On October 23,
1992, the Court entered an Order granting summary judgment to the Company, and,
on December 11, 1992, the case was dismissed.  The plaintiffs appealed the
dismissal.  On February 8, 1995, the Michigan Court of Appeals affirmed the
dismissal.

  Laird, et ano v. Gelman Sciences Inc., et ano (Circuit Court for Washtenaw
County, Michigan, Case No. 93-623 CZ).  On May 12, 1993, two owners of a
business located near the main facility of the Company brought this action
against the Company and its Chairman for damages associated with alleged
contamination of the groundwater supply of that business.  On December 1, 1994,
the parties agreed to settle this case. The Company paid the plaintiffs $30,000
and the case was dismissed on stipulation of the parties on January 3, 1995. 

  "Thermo Chem" Superfund Site, Muskegon, Michigan.  By correspondence dated
January 2, 1992, the United States Environmental Protection Agency ("USEPA")
identified the  Company as a  potentially responsible party ("PRP") under the
Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA") for past and future response costs in connection with the Thermo
Chem Superfund site, a waste chemical reclamation and disposal site.  The USEPA
issued an Administrative Order mandating remediation of the site to a number of
generator PRPs.  On July 22, 1994, the Company and the USEPA entered into a
settlement agreement under which the Company agreed to pay $124,100.  A consent
order based on that agreement became effective February 8, 1995.  Payment is
due by March 10, 1995.

                          INFORMATION AND INSTRUCTIONS

            ARTICLES OF INCORPORATION - PROFIT DOMESTIC CORPORATIONS

1.       Submit one original copy of the Articles of Incorporation.  Upon the
         filing, a microfilm copy will be prepared for the records in the
         Corporation and Securities Bureau. The original copy of the document
         will be returned as evidence of the filing.  Please complete the box
         above to reflect the name, street and number (or P.O. Box), city,
         state and zip code to which the copy is to be returned.

2.       Article I-The corporate name of a domestic profit corporation is
         required to contain one of the following words or abbreviations:
         "Corporation", "Company", "Incorporated", "Limited", "Corp.", "Co.",
         "Inc.", or "Ltd."

3.       Article II may state, in general terms, the character of the
         particular business to be carried on.  Under Section 202(b) of the
         law, it is a sufficient compliance to state substantially, alone or
         with specifically enumerated purposes, that the corporation may engage
         in any activity within the purposes for which corporations may be
         organized under the Business Corporation Act.  The law requires,
         however, that educational corporations must state their specific
         purposes.

4.       Article III (2)-The law  requires the incorporators of a domestic
         corporation having shares without par value to submit in writing the
         amount of consideration proposed to be received for each share which
         shall be allocated to stated capital.  Such stated value may be
         indicated either in Article III (2) or in a written statement
         accompanying the Articles of Incorporation.

5.       Article IV-A post office box  is not permitted to be designated as the
         address of the registered office in part 1 of Article IV.  The mailing
         address in part 2 of Article IV may differ from the address of the
         registered office only if a post office box address in the same city
         as the registered office is designated as the mailing address.

6.       Article V-The law requires one or more incorporators.
         The addresses should include a street number and name (or other
         designation), in addition to the name of the city and state.

7.       The duration of the corporation should be stated in the Articles only
         if the duration is not perpetual.

8.       The Articles must be signed in ink by each incorporator.  The names of
         the incorporators as set out in Article V should correspond with the
         signatures.

9.       Since the corporate documents are microfilmed for the Bureau's files,
         it is imperative that the document submitted for filing be legible so
         that a usable microfilm can be obtained.  Corporate documents with
         poor black and white contrast, whether due to the use of a worn
         typewriter ribbon or due to a poor quality of reproduction, will be
         rejected.

10.      An effective date, not later than 90 days after the date of filing,
         may be stated on page 3 of the Articles of Incorporation.

11.      FEES: Filing Fee.............................................$10.00
               Franchise Fee-1/2 mill (.0005) on each dollar of 
               authorized capital stock, with a minimum franchise 
               fee of.................................................$25.00
                                                                      ------

         The address of the current registered office is: 600 South Wagner
Road, Ann Arbor, Michigan 48106.  The name of the current resident agent is:
Charles Gelman.


                                 ARTICLE SIXTH

         The business and affairs of the Company shall be managed by or under
the direction of a Board of Directors consisting of not less than 3 or more
than 11 directors, the exact number of directors to be determined from time to
time solely by a resolution adopted by an affirmative vote of a majority of the
entire Board of Directors.  The directors shall be divided into three classes,
designated Class I, Class II and Class III.  Each class shall consist, as
nearly as may be possible, of one-third of the total number of directors
constituting the entire Board of Directors.  At the 1985 Annual Meeting of
Shareholders, Class I directors shall be elected for a one-year term, Class II
directors for a two-year term and Class III directors for a three-year term.
At each succeeding annual meeting of shareholders, commencing in 1986,
successors to the class of directors whose term expires at that annual meeting
shall be elected for a three-year term.

         If the number of directors is changed, any increase or decrease shall
be apportioned among the classes of directors so as to maintain the number of
directors in each class as nearly equal as possible, but in no case will a
decrease in the number of directors shorten the term of any incumbent director.
When the number of directors is increased by the Board of Directors and any
newly created directorships are filled by the Board, there shall be no
classification of the additional directors until the next annual meeting of
shareholders.

         A director shall hold office until the meeting for the year in which
his or her term expires and until his or her successor shall be elected and
shall qualify, subject, however, to prior death, resignation, retirement,
disqualification or removal from office.  Newly created directorships resulting
from an increase in the number of directors and any vacancy on the Board of
Directors may be filled by an affirmative vote of a majority of the Board of
Directors then in office.  If the number of directors then in office is less
than a quorum, such newly created directorships and vacancies may be filled by
a majority of the directors then in office, although less than a quorum, or by
the sole remaining director.  A director elected by the Board of Directors to
fill a vacancy shall hold office until the next meeting of shareholders called
for the election of directors and until his or her successor shall be elected
and shall qualify.  A director or the entire Board of Directors may be removed
only for cause.

         Notwithstanding the foregoing, whenever the holders of any one or more
classes of preferred stock or series thereof issued by the Company shall have
the right, voting separately by class or series, to elect directors at an
annual or special meeting of shareholders, the election, term of office,
filling

                                      -3-
<PAGE>   18

of vacancies and other features of such directorship shall be governed by the
terms of these Restated Articles of Incorporation applicable thereto, and such
directors so elected shall not be divided into classes pursuant to this
Article.

         This Article Sixth may not be amended by written consent of
shareholders, and may only be amended by the affirmative vote of 60% of the
shares represented at the meeting of shareholders considering the amendment, in
addition to the vote otherwise required by the Michigan Business Corporation
Act.


                                ARTICLE SEVENTH

         In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized, without stockholder
approval, to make, amend, alter or repeal the Bylaws of the corporation.



                                 ARTICLE EIGHTH

         Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this
corporation and its shareholders or any class of them, any court of equitable
jurisdiction within the State of Michigan may, on the application in a summary
way of this corporation or of any creditor or shareholder thereof, or on the
application of any receiver or receivers appointed for this corporation under
the provisions of Michigan law, or on the application of trustees in
dissolution or of any receiver or receivers appointed for this corporation
under the provisions of Michigan law, order a meeting of the creditors or class
of creditors, and/or of the shareholders or class of shareholders of this
corporation, as the case may be, to be summoned in such manner as the said
court directs.

         If a majority in number representing three-fourths in value of the
creditors or class of creditors, and/or of the shareholders or class of
shareholders of this corporation, as the case may be, agree to any compromise
or arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
shareholders or class of shareholders, of this corporation, as the case may be,
and also on this corporation.



                                 ARTICLE NINTH

any provision contained in the Articles of Incorporation, in the manner now or

Road, Ann Arbor, Michigan 48106.  The name of the current resident agent is:
Charles Gelman.



                                 ARTICLE SIXTH

         The business and affairs of the Company shall be managed by or under
the direction of a Board of Directors consisting of not less than 3 or more
than 11 directors, the exact number of directors to be determined from time to
time solely by a resolution adopted by an affirmative vote of a majority of the
entire Board of Directors.  The directors shall be divided into three classes,
designated Class I, Class II and Class III.  Each class shall consist, as
nearly as may be possible, of one-third of the total number of directors
constituting the entire Board of Directors.  At the 1985 Annual Meeting of
Shareholders, Class I directors shall be elected for a one-year term, Class II
directors for a two-year term and Class III directors for a three-year term.
At each succeeding annual meeting of shareholders, commencing in 1986,
successors to the class of directors whose term expires at that annual meeting
shall be elected for a three-year term.

         If the number of directors is changed, any increase or decrease shall
be apportioned among the classes of directors so as to maintain the number of
directors in each class as nearly equal an possible, but in no case will a
decrease in the number of directors shorten the term of any incumbent director.
When the number of directors is increased by the Board of Directors and any
newly created directorships are filled by- the Board, there shall be no
classification of the additional directors until the next annual meeting of
shareholders.

         A director shall hold office until the meeting for the year in which
his or her term expires and until his or her successor shall be elected and
shall qualify, subject, however, to prior death, resignation, retirement,
disqualification or removal from office.  Newly created directorships resulting
from an increase in the number of directors and any vacancy an the Board of
Directors may be filled by an affirmative vote of a majority of the Board of
Directors then in office.  If the number of directors then in office is less
than a quorum, such newly created directorships and vacancies may be filled by
a majority of the directors then in office, although less than a quorum, or by
the sole remaining director.  A director elected by the Board of Directors to
fill a vacancy shall hold office until the next meeting of shareholders called
for the election of directors and until his or her successor shall be elected
and shall qualify.  A director or the entire Board of Directors may be removed
only for cause.

         shares of any other class or classes or of any other series of the
         same or any other class or classes of stock of the corporation, at
         such price or prices or at such rates of exchange, and with such
         adjustments; and (f) may have such other relative, participating,
         optional or other special rights, qualifications, limitations or

         in the resolution or resolutions providing for the issue of each such
         series of Preferred Stock from time to time adopted by the Board of
         Directors pursuant to authority so to do which is hereby expressly
         vested in the Board of Directors, provided that the holders of shares
         of Preferred Stock shall have no rights to participate with the
         holders of Common Stock in any distribution of dividends in excess of

                 The Common Stock shall consist of a single class having equal
         rights, privileges and powers.  The holder of each outstanding share
         of Common Stock shall have one vote per share with respect to all
         matters submitted to a vote of shareholders.

                 The number of authorized shares of any class of stock of the
         corporation, including but without limitation the Common Stock and the
         Preferred Stock, may be increased or decreased by the affirmative vote
         of the holders of the majority of the stock of the corporation
         entitled to vote, without regard to class.

                 Whenever the vote of shareholders at a meeting thereof is
         required or permitted to be taken for or in connection with any
         corporate action, by law or by any provision herein or in the bylaws,
         the meeting and vote of shareholders may be dispensed with if the
         action is taken with the written consent of the holders of less than
         all of the stock who would have been entitled to vote upon the action
         if a meeting were held; provided that in no case shall the written
         consent be by the holders of stock having less than the minimum
         percentage of the vote required by statute for the proposed corporate
         action, and provided that prompt notice must be given to all
         shareholders of the taking of corporate action without a meeting and
         by less than unanimous written consent.

                               WARRANT AGREEMENT


TO:              Dr. Hajime Kimura, M.D., Ph.D.

FROM:            Charles Gelman

DATE:            September 2, 1994


         Pursuant to and in accordance with a resolution of the Board of
Directors of Gelman Sciences Inc. (the "Corporation") adopted at its meeting on
September 2, 1994, the Corporation hereby grants you a warrant (the "Warrant")
to purchase 9,000 shares of the Common Stock, $0.10 par value, of the
Corporation (the "Shares") at $14.25 per Share, upon the terms and conditions
contained in this Agreement.

    1.   The Warrant is not intended to be an incentive stock option within the
         meaning of the Internal Revenue Code of 1986, as amended.

    2.   The Warrant may not be transferred by you otherwise than by will or by
         the laws of descent and distribution and, during your lifetime, the
         Warrant is exercisable only by you.

    3.   Subject to the terms contained in this Agreement, you may exercise the
         Warrant in whole or in part beginning on the date of this Agreement.

    4.   This Warrant will expire (to the extent not previously exercised) on
         the tenth anniversary of the date of this Agreement, unless terminated
         earlier upon your termination of service as a member of the Board of
         Directors of the Corporation or your death, which are governed by
         Paragraphs 5 and 6 of this Agreement, respectively.

    5.   If your service as a member of the Board of Directors of the
         Corporation terminates for any reason other than your death, you have
         the right for a period of 90 days following such termination, but in
         no event subsequent to the expiration date of the Warrant, to exercise
         that portion of the Warrant, if any, which is exercisable by you on
         the date of termination of your service.
<PAGE>   2


    6.    If your service as a member of the Board of Directors of the
          Corporation terminates by reason of your death, the Warrant, to the
          extent it is exercisable on the date of your death, may be exercised
          for a period of 180 days following your death, but in no event
          subsequent to the expiration date of the Warrant, by your legal
          representative or by the person or persons to whom your rights shall
          pass by will or by the laws of descent and distribution.

    7.    The Warrant shall be exercised by giving a written notice to the
          Secretary of the Corporation.  Such notice shall specify the number
          of Shares to be purchased, the name in which you desire to have the
          shares registered, your address and your social security number and
          shall be accompanied by payment in full in cash of the aggregate
          exercise price for the number of Shares purchased and by the
          representation required by Paragraph 10 of this Agreement if the
          Shares to be issued upon exercise of the Warrant have not been
          registered under the Securities Act of 1933, as amended (the
          "Securities Act").  Such exercise shall be effective only upon the
          actual receipt of such written notice and no rights or privileges of
          a shareholder of the Corporation in respect of any of the Shares
          issuable upon exercise of any part of the Warrant shall inure to you
          or any other person who is entitled to exercise the Warrant unless
          and until certificates representing such Shares shall have been
          issued.

    8.    Nothing contained in this Agreement, nor any action taken by the
          Corporation, shall confer upon you any right with respect to
          continuation of your service as a member of the Board of Directors of
          the Corporation.

    9.    If, upon or as a result of your exercise of the Warrant, there shall
          be payable by the Corporation any amount for income tax withholding,
          you will pay such amount to the Corporation to reimburse the
          Corporation for such income tax withholding.

    10.   Unless a registration statement covering the Shares subject to the
          Warrant is in effect under the Securities Act, all Shares purchased
          upon the exercise of the Warrant shall be acquired for investment and
          not with a view to, or for, sale in connection with any distribution
          thereof and each notice of exercise of the Warrant shall be
          accompanied by a representation in writing signed by you to that
          effect.  The Corporation may place a legend upon any certificate
          representing the Shares purchased pursuant to exercise of the Warrant
          noting that the transfer of such Shares may be restricted under the
          Securities Act.

    11.   In the event that the outstanding shares of Common Stock of the
          Corporation shall be increased by a stock dividend or changed into or
          exchanged for a different number of kind of shares of stock or other
          securities of the Corporation or of another corporation, whether by
          reason of merger, consolidation, recapitalization, reclassification,
          split-up, combination of shares or otherwise, the number, price and
          kind of Shares subject to the Warrant shall be appropriately
          adjusted.

                                      2
<PAGE>   3

    12.   The Shares issued upon exercise of the Warrant may consist in whole
          or in part of the authorized and unissued or reacquired Common Stock
          of the Corporation.

                                                   Sincerely yours,



                                                   Charles Gelman
                                                   Chairman of the Board and CEO


    The above is agreed to and accepted:
