                         AMENDMENT TO CONSENT JUDGMENT




   2
        A Consent Judgment was entered in this case on October 26, 1992. The
Consent Judgment requires Defendant, Gelman Sciences, Inc., to implement
various remedial actions to address environmental contamination in the vicinity
of Defendant's property in Scio Township, subject to the approval of the
Michigan Department of Natural Resources ("MDNR").

        Since the entry of the Consent Judgment, Executive Order 1995-18
reorganized the MDNR and transferred the MDNR functions relevant to this action
to a new Michigan Department of Environmental Quality ("MDEQ").

        Since the entry of the Consent Judgment, state environmental laws
relevant to this action, including the former Michigan Environmental Response
Act, 1982 PA 307, as amended, have been recodified and amended as Part 201 of
the Natural Resources and Environmental Protection Act ("NREPA"), 1994 PA 451,
as amended, MCL 324.20101 et. seq. Those amendments have changed cleanup
criteria, MCL 324.20120a, and, in MCL 324.20102a, required the MDEQ to approve
requests by persons implementing response activities to change plans for such
response activity to be consistent with the new cleanup criteria.

        Defendant has requested the MDEQ to approve changes in the Remedial
Action Plan attached to the Consent Judgment. The MDEQ has agreed that certain
changes to the Remedial Action Plan are appropriate.

        The Parties have agreed that it is appropriate to establish schedules
for submittal and completion of certain remaining response activities
at the site.


                                       1
   3

        THEREFORE, the Parties agree to this Amendment to the Consent Judgment
("Amendment") and such Amendment is ordered, adjudged, and decreed as follows:

        FIRST, modify Sections III.G,H, and N to read as follows:

        G.  "Groundwater Contamination" or "Groundwater Contaminant" shall
mean 1,4-dioxane in groundwater at a concentration in excess of 77 micrograms
per liter ("ug/1") as determined by the sampling and analytical method(s)
described in Attachment B.

        H.  "MDEQ" shall mean the Michigan Department of Environmental Quality,
the successor to the Michigan Department of Natural Resources ("MDNR") and to
the Water Resources Commission. All references to the "MDNR" or to the "Water
Resources Commission" in this Consent Judgment shall be deemed to refer to the
MDEQ. 

        N.  "Soil Contamination" or "Soil Contaminant" shall mean 1,4-dioxane
in soil at a concentration in excess of 1500 ug/kg as determined by the
sampling and analytical method(s) described in Attachment C or other higher
concentration limit derived by means consistent with Mich Admin Code R
299.5711(2) or MCL 324.20120a.


                                       2

   4

        SECOND, modify Section V.A.5 to read as follows:

        5.  Treatment and Disposal.  Groundwater extracted by the purge wells(s)
in the Evergreen System shall be treated as necessary using ultraviolet light
and oxidizing agents or such other method as approved by the MDEQ and disposed
of in accordance with the Evergreen System design approved by the MDNR or MDEQ.
The options for such disposal are the following:

        THIRD, insert new Section V.A.7 to read as follows:

        7.  On August 15, 1996, Defendant submitted to the MDEQ a written
report based upon groundwater monitoring data and modeling, evaluating whether
the existing Evergreen System is intercepting and containing the leading edge
of the plume of groundwater contamination in the vicinity of the Evergreen
Subdivision area. Unless that report demonstrates to the MDEQ's satisfaction
that the existing Evergreen System is meeting that objective, Defendant shall,
at MDEQ's written request, install additional monitoring and/or purge wells as
needed to ensure that the objectives of the Evergreen System are achieved. 

        FOURTH, modify Section V.B.1 to read as follows:

        1.  Objectives.  For purposes of the Consent Judgment, the "Core Area"
means that portion of the Unit C(3) aquifer containing 1,4-dioxane in a
concentration exceeding 500 ug/1. The objectives of the Core System are to
intercept and contain the migration of groundwater from the Core Area and
remove contaminated 


                                       3
   5

groundwater from the Core Area until the termination criterion for the Core
System in Section V.D.1 is satisfied.

        FIFTH, modify the last clause of Section V.B.2 to read as follows:

        (c)  the discharge level for 1,4-dioxane in groundwater to be
reinjected in the Core Area shall be established based upon performance of
further tests by Defendant on the treatment technology and shall, in any event,
be less than 77 ug/1.

        SIXTH, modify Section V.B.4 to read as follows:

        4.  Surface Water Discharge Alternative.  Defendant shall, not later
than September 30, 1996, submit to MDEQ for review and approval Defendant's
design for the Core System, a schedule for implementing the design, an
operation and maintenance plan for the System, and an effectiveness monitoring
plan for the System. The Core System shall include groundwater purge wells as
necessary to meet the objectives described in Section V.B.1. The design shall
include, at a minimum, three purge wells.

        Purged groundwater form the Core Area System shall be treated with
ultraviolet light and oxidizing agent(s) or such other method approved by the
MDEQ to reduce 1,4-dioxane concentrations to the level as required by NPDES
Permit No. MI-008453, as amended or reissued. Discharge to the Honey Creek
tributary shall be in accordance with NPDES Permit No. MI-008453, as amended or
reissued. 


                                       4

   6


        SEVENTH, modify Section V.B.5 to read as follows:

        5.  Implementation of Program. Upon approval by the MDEQ, Defendant
shall install the Core System according to the approved schedule and thereafter
continuously operate and maintain the System according to the approved plans
until Defendant is authorized to terminate operation pursuant to Section V.D.
Defendant may thereafter, and at its option, continue purge operations as
provided in this Section. 

        In any event, Defendant shall, beginning not later than December 28,
1996, continuously operate groundwater purge wells in the Core Area System at
the rate of at least 65 gallons per minute until termination is authorized
pursuant to this Judgment. This initial, minimum purging rate requirement is
intended solely as a means of assuring progress toward remediation of the Core
Area by a date certain and shall not be construed as an indication that the
rate is sufficient to meet the objectives of the Core System. 

        EIGHTH, add a new Section V.B.7 to read as follows: 

        7.  Modification of Program.  Defendant may, at its option, propose to
MDEQ for review and approval modification(s) to the Core System, provided such
modification(s) will satisfy the objectives of the Consent Judgment as defined
in Section V.B.1. Any proposed modification involving groundwater reinjection
shall satisfy the requirements of Section V.B.3. If approved by the MDEQ, the
modification(s) shall be implemented according to MDEQ approval plan(s) and
schedule(s). 


                                       5
   7
     NINTH, modify Section V.C.3 to read as follows:

     3.  Remedial Investigation. No later than April 28, 1997, Defendant shall
submit to the MDEQ for its review and approval a revised work plan for remedial
investigation and design of the Western System and a schedule for implementing
the revised work plan. The revised work plan shall include plans for
installation of a series of test/purge wells, conduct of an aquifer performance
test(s), groundwater monitoring, an operations and maintenance plan, and system
design. 

     TENTH, modify Section V.D.1 as follows:

     Change 3 ug/1 to 77 ug/1 and change 60 ug/1 to 77 ug/1.

     ELEVENTH, modify Section V.E.1 to read as follows:

     1.  For systems with a termination criterion of 77 ug/1, for a period of
five (5) years after cessation of operation of any purge well, Defendant shall
continue monitoring the purge well and/or associated monitoring wells, in
accordance with the approved monitoring plan, to verify that the concentration
of 1,4-dioxane in the groundwater does not exceed the termination criterion. If
such post-termination monitoring reveals the presence of 1,4-dioxane in excess
of the termination criterion, Defendant shall immediately notify MDEQ and shall
collect a second sample within fourteen (14) days of such finding. If the
second sample confirms the presence of 1,4-dioxane in excess of the termination
criterion, Defendant shall restart the associated purge well system.

                                       6

   8

        TWELFTH, add a new Section V.F to read as follows: 

        F.  Minimum Monitoring.  In the event that any groundwater system
provided for in Section V is not operating for any reason other than compliance
with the termination criteria of Section V.D, Defendant shall, not later than
November 30, 1996, and at least semi-annually thereafter, collect and analyze
for 1,4-dioxane samples from groundwater monitoring wells designated MW-15D,
MW-16, MW-21, MW-28, MW-40S, MW-40D, MW-41S, MW-41D, and MW-43, and report the
results to MDEQ. Such minimum monitoring shall not obligate Defendant to
duplicate monitoring required under any MDEQ-approved monitoring plan for a
groundwater system. 

        THIRTEENTH, modify the first paragraph of Section VI to read as
follows: 

        Defendant shall design, install, operate, and maintain the systems
described below to control, remove, and treat (as required) soil contamination
at the GSI Property. The overall objective of these systems shall be to: (a)
prevent the migration of 1,4-dioxane from contaminated soils into any aquifer in
concentrations that cause groundwater contamination; (b) prevent venting of
groundwater contamination into Honey Creek Tributary of 1,4-dioxane in
quantities which cause the concentration of 1,4-dioxane at the
groundwater-surface water interface of the Tributary to exceed 2000 ug/l; and
(c) prevent venting of groundwater contamination to Third Sister Lake in
quantities which cause the concentration of 1,4-dioxane at the
groundwater-surface water interface of the Lake to exceed 2000 ug/l. Defendant
also shall implement a monitoring plan to verify the effectiveness of these
systems. 


                                       7

     FOURTEENTH, modify Section VI.A.1 to read as follows:

     1.  Objectives.  The objectives of this System are to: (a) remove
contaminated groundwater from the Marshy Area located north of former Ponds I
and II; (b) reduce the migration of contaminated groundwater from the Marshy
Area into other aquifers; and (c) prevent the discharge of contaminated
groundwater from the Marshy Area into the Honey Creek Tributary in quantities
which cause the concentration of 1,4-dioxane at the groundwater-surface water
interface of the Tributary to exceed 2000 ug/l.

     FIFTEENTH, modify Sections VI.A.2 and VI.A.4 to read as follows:

     2.  Pilot Test and Design.  No later than December 28, 1996, Defendant
shall begin the Extended Pilot Test according to the plan conditionally
approved by MDEQ on July 26, 1995. No later than March 1, 1998, Defendant shall
submit to MDEQ for review and approval the Pilot Test Report, final design, and
effectiveness monitoring plan. No later than June 13, 1998, Defendant shall
submit to MDEQ for review and approval the operation and maintenance plan.

     4.  Installation and Operation.  Upon approval of the final design by MDEQ
and in any event not later than September 27, 1998, Defendant shall complete
installation of the system according to the approved design and begin operation.
Defendant shall thereafter continuously operate the system according to the
approved plans until it is authorized to shut down the system pursuant to
Section VI.D of the Consent Judgment.

        1.  Objectives.  The objectives of this program shall be to meet the
overall objective of Section VI upon completion of the program and to prevent
the discharge of groundwater contamination into Third Sister Lake in quantities
which cause the concentration of 1,4-dioxane at the groundwater-surface water
interface of Third Sister Lake to exceed 2000 ug/l. 

        SEVENTEENTH, modify Section VI.B.3 by striking the paragraph. 

        EIGHTEENTH, modify Section VI.C.2 to read as follows: 

        2.  Defendant shall, no later than November 30, 1996, submit to MDEQ
for review and approval a revised soils remediation plan for addressing
identified areas of soil contamination. The areas to be addressed include the
burn pit; the former Pond I area; the former Pond II area; the form Lift
Station area; and Pond III. The plan submitted by Defendant shall be consistent
with cleanup criteria as provided in MCL 324.20120a. 

        The Defendant's proposal must attain the overall objectives of Section
VI. 

        NINETEENTH, modify Section VI.D.1.a to read as follows: 

        (a)  Except as otherwise provided pursuant to Section VI.D.3, Defendant
shall continue to operate the Marshy Area System until six (6) consecutive
monthly tests of samples from the purge well(s) and associated monitoring
well(s) fail to detect the 


                                       9

   11
presence of 1,4-dioxane in groundwater at a concentration at or above 500 ug/l.
