     (b) Cash Management After the Cut-off Date.  Commercial Intertech and CUNO
shall establish and maintain a separate cash management system with respect to
the CUNO Business in accordance with past practice.

     SECTION 3.03   The CUNO Board.  At the Distribution Date, the CUNO Board
shall consist of, and CUNO and Commercial Intertech shall take all actions which
may be required to elect or otherwise appoint as directors of CUNO on or prior
to the Distribution Date, the persons named on SCHEDULE 3.03.

     SECTION 3.04  Business, Administrative and Support Services.

     (a) Coverage.  Commercial Intertech and its predecessors have historically
provided various business, administrative and support Services to its
Subsidiaries, including CUNO and the CUNO Subsidiaries. From and after the
Distribution Date, CUNO and the CUNO Subsidiaries will be responsible for
procuring or providing such Services in their own right. To the extent CUNO and
the CUNO Subsidiaries desire to continue certain of the Services following

                                       9

 
the Distribution Date, Commercial Intertech agrees to provide the Services to
CUNO and the CUNO Subsidiaries as set forth in this SECTION 3.04.

     (b) Agreement to Provide Service. Commercial Intertech, to facilitate
transition by CUNO to standalone capability, agrees to provide the Services to
CUNO or any CUNO Subsidiary following the Distribution Date for a period up to
twelve (12) months from the Distribution Date; provided, however, that certain
Services, upon mutual agreement of CUNO and Commercial Intertech, may be
extended beyond such 12-month period as necessary to assist in the year-end
closing process for the first full fiscal year following the Distribution Date.
Any and all of the Services to be provided by Commercial Intertech may be
terminated prior to completion of the 12-month transition period upon the mutual
consent of both parties.

     (c) Scope of Services.  If CUNO or any CUNO Subsidiary exercises the
election to receive Services set forth in part (b) above, Commercial Intertech
shall perform such specified Services in a manner consistent with the manner in
which such Services have been performed prior to the Distribution Date.
Commercial Intertech will also assist CUNO or the CUNO Subsidiary, as
appropriate, in transferring data to CUNO from Commercial Intertech's systems
and establishing interconnection between systems, and otherwise transferring the
operation of the Services to CUNO or the CUNO Subsidiary.

     (d) Compensation.  Commercial Intertech shall be paid by CUNO or the CUNO
Subsidiary, as appropriate, for the Services provided, in accordance with past
practice and corporate assessment methods at rates comparable to those charged
to CUNO by Commercial Intertech for similar services provided prior to the
Distribution. Such rates are considered by CUNO and Commercial Intertech to be
reasonable approximations of market-based rates for purposes of this Agreement.
Such services will be invoiced to CUNO by Commercial Intertech on a monthly
basis and are payable by CUNO within 30 days of the invoice date.

     (e) Consents of Third Parties.  Commercial Intertech shall use commercially
reasonable efforts, at CUNO's direction and expense, to obtain any consents or
licenses from third parties necessary for the continuation of the requested
Services; provided that Commercial Intertech shall have no obligation to provide
Services for which such consent is required and shall not have been obtained.

     SECTION 3.05  Insurance.

     (a) Coverage. Commercial Intertech has historically provided Policies which
include CUNO and the CUNO Subsidiaries within the definition of the named
insured. Except for those Policies issued in the name of CUNO or any CUNO
Subsidiary, coverage of CUNO and the CUNO Subsidiaries shall cease under the
Policies as of the Distribution Date. From and after the Distribution Date, CUNO
and CUNO Subsidiaries will be responsible for obtaining and maintaining
insurance coverages in their own right. Commercial Intertech shall retain the
Policies, together with the rights, benefits and privileges thereunder. It is
agreed that CUNO and the CUNO Subsidiaries shall have the right to present
claims under such Policies for insured

                                      10

 
incidents occurring from the date said coverage first commenced until the
Distribution Date to the extent that the terms and conditions of any such
Policies so allow. It is understood that any such Policies written on a "claims
made" basis rather than "occurrence" basis may not provide coverage to CUNO and
the CUNO Subsidiaries for incidents occurring prior to the Distribution Date but
which are first reported after the Distribution Date.

     (b) Administration and Reserves.  From and after the Cut-off Date:

             (i) Commercial Intertech shall be responsible for the (A) Premium
     Administration of all Policies, and (B) Claims Administration with
     respect to the Commercial Intertech Liabilities; provided, that the
     retention of the Policies by Commercial Intertech is in no way intended to
     limit, inhibit or preclude any right to insurance coverage for any insured
     claim of a named insured under the Policies, including but not limited to
     CUNO and the CUNO Subsidiaries;

             (ii)  CUNO or a CUNO Subsidiary, as appropriate, shall be
     responsible for the Claims Administration with respect to the CUNO
     Liabilities;

             (iii) Commercial Intertech or a Commercial Intertech Subsidiary,
     as appropriate, shall be entitled to reserves or the benefit of reserves
     held by any insurance carrier, with respect to Commercial Intertech
     Liabilities; and

             (iv)   CUNO or a CUNO Subsidiary, as appropriate, shall be entitled
     to reserves, or the benefit of reserves held by any insurance carrier, with
     respect to CUNO Liabilities.

     (c) Insurance Premiums. Commercial Intertech shall pay the premiums, to the
extent that CUNO or a CUNO Subsidiary does not pay premiums with respect to CUNO
Liabilities (retrospectively-rated or otherwise), as required under the terms
and conditions of the respective Policies, whereupon CUNO or a CUNO Subsidiary,
as appropriate, shall upon receipt of a copy of the retrospective-rating
adjustment forthwith reimburse Commercial Intertech or a Commercial Intertech
Subsidiary, as appropriate, for that portion of such premiums paid by Commercial
Intertech as are attributable to the CUNO Liabilities.

     (d) Insurance Proceeds. Proceeds received with respect to claims made under
the Policies shall be paid to Commercial Intertech with respect to the
Commercial Intertech Liabilities and to CUNO with respect to the CUNO
Liabilities.

     (e) Agreement for Waiver of Conflict and Shared Defense. In the event that
a Policy or Policies provide coverage for both Commercial Intertech and CUNO
relating to the same occurrence, Commercial Intertech and CUNO agree to jointly
defend and to waive any conflict of interest necessary to the conduct of that
joint defense. Nothing in this subsection (e) shall be construed to limit or
otherwise alter in any way the indemnity obligations of the parties to this
Agreement, including those created by this Agreement, by operation of law or
otherwise.

                                       11

 
     (f) Directors' and Officers' Insurance. Commercial Intertech shall use
reasonable efforts to cause the persons currently serving as officers and/or
directors of Commercial Intertech who will become effective as of the
Distribution Date officers and/or directors of CUNO to be covered for a period
of three years from the Distribution Date by the directors' and officers'
liability insurance policy maintained by Commercial Intertech (provided that
Commercial Intertech may substitute therefor policies of at least the same
coverage and amounts containing terms and conditions which are not less
advantageous than such policy) with respect to matters covered under the
existing policy occurring prior to the Distribution Date which were committed by
such officers and/or directors in their capacity as such; provided however, that
in no event shall Commercial Intertech be required to expend with respect to any
year more than the Insurance Amount to maintain or procure insurance coverage
pursuant hereto; provided further, that if Commercial Intertech is unable to
maintain or obtain the insurance called for by this SECTION 3.07(F) 3.05(F),
Commercial Intertech shall use reasonable efforts to obtain as much comparable
insurance as available for the Insurance Amount. In the event Commercial
Intertech or any of its successors or assigns (i) consolidates with or merges
into any other Person and shall not be the continuing or surviving corporation
or entity of such consolidation or merger, or (ii) transfers or conveys all or
substantially all of its properties and assets to any Person, then, and in each
such case, to the extent necessary, proper provision shall be made so that the
successors and assigns of Commercial Intertech assume the obligations set forth
in this SECTION 3.07(F) 3.05(F). The provisions of this SECTION 3.07(F) 3.05(F)
are intended to be for the benefit of, and shall be enforceable by, each such
officer and director and his or her heirs and representatives.

     SECTION 3.06  Use of Names.

     (a) Use of CUNO Name. Any existing printed material showing any affiliation
or connection of Commercial Intertech or any of its Subsidiaries with CUNO or
any CUNO Subsidiary may be used by Commercial Intertech and its Subsidiaries
only for a period ending eight (8) months after the Distribution Date. On and
after the Distribution Date, Commercial Intertech and its Subsidiaries shall not
otherwise represent to third parties that any of them is affiliated with CUNO or
any CUNO Subsidiary.

     (b) Use of Commercial Intertech Name.  Any existing printed material
showing any affiliation or connection of CUNO or any of its Subsidiaries with
Commercial Intertech or any Commercial Intertech Subsidiary may be used by CUNO
and its Subsidiaries only for a period ending eight (8) months after the
Distribution Date.  On and after the Distribution Date, CUNO and its
Subsidiaries shall not otherwise represent to third parties that any of them is
affiliated with Commercial Intertech or any Commercial Intertech Subsidiary.

     SECTION 3.07  Transfers Not Effected Prior to the Distribution;
Transfers Deemed Effective as of the Cutoff Date.  To the extent that any
transfers and assumptions contemplated by this ARTICLE III shall not have been
consummated prior to the Distribution Date, the parties shall cooperate to
effect such transfers as promptly following the Distribution Date as shall be
practicable, it nonetheless being agreed and understood by all the parties that
no party shall be liable in any manner to any other party for any failure of any
of the transfers contemplated by 

                                       12

 
this Article III to be consummated prior to the Distribution Date. Subject to
the provisions of SECTION 2.03, nothing herein shall be deemed to require the
transfer of any assets or the assumption of any Liabilities which by their terms
or operation of law cannot be transferred or assumed; provided, however, that
Commercial Intertech and CUNO shall, and shall cause their respective
Subsidiaries to, cooperate to seek to obtain any necessary consents or approvals
for the transfer of all assets and Liabilities contemplated to be transferred
pursuant to this ARTICLE III, In the event that any such transfer of assets
(other than capital stock of corporations to be transferred hereunder) or
Liabilities has not been consummated, effective as of and after the Cut-off
Date, the party retaining such asset or Liability shall thereafter hold such
asset for the party entitled thereto (at the expense of the party entitled
thereto) and retain such Liability for the account of the party by whom such
Liability is to be assumed, and take such other action as may be reasonably
requested by the party to whom such asset is to be transferred, or by whom such
Liability is to be assumed, as the case may be, in order to place such party,
insofar as reasonably possible, in the same position as would have existed had
such asset or Liability been transferred as of the Cut-off Date. As and when any
such asset or Liability becomes transferable, such transfer shall be effected
forthwith. The parties agree that, as of the Cut-off Date, each party hereto
shall be deemed to have assumed in accordance with the terms of this Agreement
and the Ancillary Agreements all of the Liabilities, and all duties, obligations
and responsibilities incident thereto, which such party is required to assume
pursuant to the terms hereof and thereof.

     SECTION 3.08  Commercial Intertech Guarantees.  CUNO shall use its
reasonable efforts to cause itself or one of its Affiliates to be substituted in
all respects for Commercial Intertech in respect of all obligations of
Commercial Intertech under any guarantee each of the guarantees and comfort
letters set forth on SCHEDULE 1.02, effective as of the next maturity date
after the date hereof of each of the related agreements with respect to which
such guaranty or comfort letter was issued.

     SECTION 3.09.   Corporate Opportunities.  The parties hereto
acknowledge that certain of the directors and officers of CUNO or a CUNO
Subsidiary may also be a director or officer of Commercial Intertech or a
Commercial Intertech Subsidiary following the Distribution Date.  In connection
with the foregoing, the parties hereto agree that following the Distribution
Date, no opportunity, transaction, agreement or other arrangement of which an
officer or director of Commercial Intertech, a Commercial Intertech Subsidiary,
or any other Person in which Commercial Intertech acquires a financial interest
or is a party, has knowledge, shall be the property or corporate opportunity of
CUNO or any CUNO Subsidiary, even if such opportunity, transaction, agreement or
other arrangement relates to the ownership of interests in or the management and
operation of the CUNO Business.

                                       13

 
                                  ARTICLE IV

                                INDEMNIFICATION
                                ---------------

     SECTION 4.01  Indemnification by Commercial Intertech.  Except with
respect to claims for proceeds of Policies or other amounts received, which
shall be governed by SECTION 3.05 and SECTION 4.03, Commercial Intertech
shall indemnify, defend and hold harmless the CUNO Indemnitees from and against
each of the following:

     (a) The Commercial Intertech Liabilities and any and all Losses of the CUNO
Indemnitees arising out of, or due to the failure or alleged failure of
Commercial Intertech or any of its Affiliates to pay, perform or otherwise
discharge in due course any of the Commercial Intertech Liabilities.

     (b) All Losses of any CUNO Indemnitee arising (whether before, on or after
the Distribution Date) in connection with the Commercial Intertech Assets or the
Commercial Intertech Businesses, whether any such Losses relate to events,
occurrences or circumstances occurring or existing, or whether any such Losses
are asserted, before, on or after the Distribution Date.

     (c) All Losses of any CUNO Indemnitee arising out of or based upon any
untrue statement or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, with respect to the
information set forth in the following parts of any preliminary or final Form 10
or any amendment thereto:  Commercial Intertech's letter to its stockholders or
under the headings "Risk Factors -- Effects on Commercial Intertech Common
Stock," "Introduction," "The Distribution," "Management -- Executive
Compensation," and "Selected Pro Forma Financial and Other Data" (other than
with respect to information provided by the CUNO Group), and any information
under "Information Statement Summary" derived from information contained under
such headings.

     Notwithstanding anything in this SECTION 4.01 to the contrary, neither
Commercial Intertech nor any Commercial Intertech Subsidiary shall have any
liability whatsoever to either CUNO or any CUNO Subsidiary in respect of any
Tax, except as otherwise provided in the Tax Allocation Agreement.

     SECTION 4.02   Indemnification by CUNO.  Except with respect to claims
for proceeds of Policies or other amounts received, which shall be governed by
SECTION 3.07 3.05 and SECTION 4.03, CUNO shall indemnify, defend and hold
harmless the Commercial Intertech Indemnitees from and against each of the
following:

     (a) The CUNO Liabilities and any and all Losses of the Commercial Intertech
Indemnitees arising out of, or due to the failure or alleged failure of CUNO or
any of its Affiliates to pay, perform or otherwise discharge in due course any
of the CUNO Liabilities.

                                       14

 
     (b) All Losses of any Commercial Intertech Indemnitee arising (whether
before, on or after the Distribution Date) in connection with the CUNO Assets or
the CUNO Business, whether any such Losses relate to events, occurrences or
circumstances occurring or existing, or whether any such Losses are asserted,
before, on or after the Distribution Date.

     (c) All Losses of any Commercial Intertech Indemnitee arising out of or
based upon any untrue statement or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, with respect
to all information set forth in any preliminary or final Form 10 or any
amendment thereto, except for information set forth under the headings specified
in SECTION 4.01(c), with respect to which Commercial Intertech will indemnify
CUNO, and except for information set forth under the headings "Arrangements
Between the Company and Commercial Intertech," and "Certain Transactions in
connection with the Distribution."

     Notwithstanding anything in this SECTION 4.02 to the contrary, neither CUNO
nor any CUNO Subsidiary shall have any liability whatsoever to either Commercial
Intertech or any Commercial Intertech Subsidiary in respect of any Tax, except
as otherwise provided in the Tax Allocation Agreement.

     SECTION 4.03  Limitations on Indemnification Obligations.

     (a) The amount which any Indemnifying Party is or may be required to pay to
any Indemnitee pursuant to SECTION 4.01 or SECTION 4.02 shall be reduced
(including, without limitation, retroactively) by any proceeds of Policies or
other amounts actually recovered by or on behalf of such Indemnitee, in
reduction of the related Loss. If an Indemnitee shall have received the
Indemnity Payment required by this Agreement from an Indemnifying Party in
respect of any Loss and shall subsequently actually receive proceeds of Policies
or other amounts in respect of such Loss, then such Indemnitee shall pay to such
Indemnifying Party a sum equal to the amount actually received (up to but not in
excess of the amount of any Indemnity Payment made hereunder). An insurer who
would otherwise be obligated to pay any claim shall not be relieved of the
responsibility with respect thereto, or, solely by virtue of the indemnification
provisions hereof, have any subrogation rights with respect thereto, it being
expressly understood and agreed that no insurer or any other third party shall
be entitled to a "windfall" (i.e., a benefit they would not be entitled to
receive in the absence of the indemnification provisions) by virtue of the
indemnification provisions hereof.

     (b) If any Indemnitee realizes a Tax benefit or detriment in one or more
Tax periods by reason of having incurred an Indemnifiable Loss for which such
Indemnitee receives an Indemnity Payment from an Indemnifying Party, then such
Indemnitee shall pay to such Indemnifying Party an amount equal to the Tax
benefit or such Indemnifying Party shall pay to such Indemnitee an additional
amount equal to the Tax detriment (taking into account any Tax detriment
resulting from the receipt of such additional amounts), as the case may be. The
amount of any Tax benefit or any Tax detriment for a Tax period realized by an
Indemnitee by reason of having incurred an Indemnifiable Loss shall be deemed to
equal the product obtained
                                       15

 
by multiplying (i) the amount of any deduction or inclusion in income for such
period resulting from such Indemnifiable Loss or the payment thereof, as the
case may be, by (ii) the highest applicable marginal Tax rate for such period
(provided, however, that the amount of any Tax benefit attributable to an amount
that is creditable shall be deemed to equal the amount of such creditable item).
Any payment due under this SECTION 4.03(b) with respect to a Tax benefit or Tax
detriment realized by an Indemnitee in a Tax period shall be due and payable
within 30 days from the time the return for such Tax period is due, without
taking into account any extension of time granted to the party filing such
return.

     SECTION 4.04      Procedures for Indemnification.

     (a) Procedures for Indemnification of Third Party Claims shall be as
         follows:

             (i) If an Indemnitee shall receive notice or otherwise learn of a
     Third Party Claim with respect to which an Indemnifying Party may be
     obligated to provide  indemnification pursuant to SECTION 4.01, SECTION
     4.02, or any other Section of this Agreement, such Indemnitee shall give
     such Indemnifying Party written notice thereof promptly after becoming
     aware of such Third Party Claim; provided that the failure of any
     Indemnitee to give notice as provided in this SECTION 4.04(a)(i) shall not
     relieve the  related Indemnifying Party of its obligations under this
     ARTICLE IV, except to the extent that such Indemnifying Party is prejudiced
     by such failure to give notice.  Such notice shall describe the Third Party
     Claim in reasonable detail and, if ascertainable, shall indicate the amount
     (estimated if necessary) of the Loss that has been or may be sustained by
     such Indemnitee.

             (ii) An Indemnifying Party may elect to defend or to seek to settle
     or compromise, at such Indemnifying Party's own expense and by such
     Indemnifying Party's own counsel, any Third Party Claim. Within 30 days of
     the receipt of notice from an Indemnitee in accordance with SECTION
     4.04(a)(i) (or sooner, if the nature of such Third Party Claim so
     requires), the Indemnifying Party shall notify the Indemnitee of its
     election whether the Indemnifying Party will assume responsibility for
     defending such Third Party Claim, which election shall specify any
     reservations or exceptions. After notice from an Indemnifying Party to an
     Indemnitee of its election to assume the defense of a Third Party Claim,
     such Indemnifying Party shall not be liable to such Indemnitee under this
     ARTICLE IV for any legal or other expenses (except expenses approved in
     advance by the Indemnifying Party) subsequently incurred by such Indemnitee
     in connection with the defense thereof; provided that, if the defendants in
     any such claim include both the Indemnifying Party and one or more
     Indemnitees and in any Indemnitee's reasonable judgment a conflict of
     interest between one or more of such Indemnitees and such Indemnifying
     Party exists in respect of such claim or if the Indemnifying Party shall
     have assumed responsibility for such claim with any reservations or
     exceptions, such Indemnitees shall have the right to employ separate
     counsel to represent such Indemnitees and in that event the reasonable fees
     and expenses of such separate counsel (but not more than one separate
     counsel reasonably satisfactory
 

                                       16

 
     to the Indemnifying Party) shall be paid by such Indemnifying Party. If an
     Indemnifying Party elects not to assume responsibility for defending a
     Third Party Claim, or fails to notify an Indemnitee of its election as
     provided in this SECTION 4.04(a)(ii), such Indemnitee may defend or
     (subject to the remainder of this SECTION 4.04(a)(ii)) seek to compromise
     or settle such Third Party Claim. Notwithstanding the foregoing, neither an
     Indemnifying Party nor an Indemnitee may settle or compromise any claim
     over the objection of the other; provided, however, that consent to
     settlement or compromise shall not be unreasonably withheld. Neither an
     Indemnifying Party nor an Indemnitee shall consent to entry of any judgment
     or enter into any settlement of any Third Party Claim which does not
     include as an unconditional term thereof the giving by the claimant or
     plaintiff to such Indemnitee, in the case of a consent or settlement by an
     Indemnifying Party, or the Indemnifying Party, in the case of a consent or
     settlement by the Indemnitee, of a written release from all liability in
     respect to such Third Party Claim.

             (iii)  If an Indemnifying Party chooses to defend or to seek to
     compromise or settle any Third Party Claim, the related Indemnitee shall
     make available to such Indemnifying Party any personnel or any books,
     records or other documents within its control or which it otherwise has the
     ability to make available that are necessary or appropriate for such
     defense, settlement or compromise, and shall otherwise cooperate in the
     defense, settlement or compromise of such Third Party Claims, subject to
     the establishment of appropriate confidentiality arrangements which are
     reasonably satisfactory to Commercial Intertech and CUNO.

             (iv) Notwithstanding anything else in this SECTION 4.04 to the
     contrary, if an Indemnifying Party notifies the related Indemnitee in
     writing of such Indemnifying Party's desire to settle or compromise a Third
     Party Claim on the basis set forth in such notice (provided that such
     settlement or compromise includes as an unconditional term thereof the
     giving by the claimant or plaintiff of a written release of the Indemnitee
     from all liability in respect thereof) and the Indemnitee shall notify the
     Indemnifying Party in writing that such Indemnitee declines to accept any
     such settlement or compromise, such Indemnitee may continue to contest such
     Third Party Claim, free of any participation by such Indemnifying Party, at
     such Indemnitee's sole expense. In such event, the obligation of such
     Indemnifying Party to such Indemnitee with respect to such Third Party
     Claim shall be equal to (i) the costs and expenses of such Indemnitee prior
     to the date such Indemnifying Party notifies such Indemnitee of the offer
     to settle or compromise (to the extent such costs and expenses are
     otherwise indemnifiable hereunder) plus (ii) the lesser of (A) the amount
     of any offer of settlement or compromise which such Indemnitee declined to
     accept and (B) the actual out-of-pocket amount such Indemnitee is obligated
     to pay subsequent to such date as a result of such Indemnitee's continuing
     to pursue such Third Party Claim.

     (b) Any claim on account of a Loss which does not result from a Third Party
Claim shall be asserted by written notice given by the Indemnitee to the related
Indemnifying Party.  Such Indemnifying Party shall have a period of 30 days
after the receipt of such notice within 

                                       17


which to respond thereto. If such Indemnifying Party does not respond within
such 30-day period, such Indemnifying Party shall be deemed to have refused to
accept responsibility to make payment. If such Indemnifying Party does not
respond within such 30-day period or rejects such claim in whole or in part,
such Indemnitee shall be free to pursue such remedies as may be available to
such party under this Agreement or under applicable law.

     (c) In addition to any adjustments required pursuant to SECTION 4.03, if
the amount of any Loss shall, at any time subsequent to the payment required by
this Agreement, be reduced by recovery, settlement or otherwise, the amount of
such reduction, less any expenses incurred in connection therewith, shall
promptly be repaid by the Indemnitee to the Indemnifying Party.

     (d) In the event of payment by an Indemnifying Party to any Indemnitee in
connection with any Third Party Claim, such Indemnifying Party shall be
subrogated to and shall stand in the place of such Indemnitee as to any events
or circumstances in respect of which such Indemnitee may have any right or claim
relating to such Third Party Claim against any claimant or plaintiff asserting
such Third Party Claim or against any other Person.  Such Indemnitee shall
cooperate with such Indemnifying Party in a reasonable manner, and at the cost
and expense of such Indemnifying Party, in prosecuting any subrogated right or
claim.

     SECTION 4.05   Remedies Cumulative. The remedies provided in this
ARTICLE IV shall be cumulative and shall not preclude assertion by any
Indemnitee of any other rights or the seeking of any and all other remedies
against any Indemnifying Party.

     SECTION 4.06   Survival of Indemnities.  The obligations of each of
Commercial Intertech and CUNO under this ARTICLE IV shall survive the sale or
other transfer by it of any assets or businesses or the assignment by it of any
Liabilities, with respect to any Loss of the other related to such assets,
businesses or Liabilities.

                                   ARTICLE V

                             ACCESS TO INFORMATION
                             ---------------------

     SECTION 5.01   Access to Information.  From and after the Distribution
Date, Commercial Intertech shall afford to CUNO and its Representatives
reasonable access (including using reasonable efforts to give access to Persons
or firms possessing information) and duplicating rights during normal business
hours to all Information within Commercial Intertech's possession or in the
possession of a Commercial Intertech Subsidiary relating to CUNO, any CUNO
Subsidiary, any CUNO Assets or the CUNO Business, insofar as such access is
reasonably required by CUNO or any CUNO Subsidiary.  Similarly, CUNO shall
afford to Commercial Intertech and its Representatives reasonable access
(including using reasonable efforts to give access to Persons or firms
possessing Information) and duplicating rights during normal business hours to
Information within CUNO's possession relating to Commercial Intertech or any

     SECTION 6.01   Complete Agreement; Construction.  This Agreement and the
Ancillary Agreements, including any schedules and exhibits hereto or thereto,
and other agreements and documents referred to herein, shall constitute the
entire agreement between the parties with respect to the subject matter hereof
and shall supersede all previous negotiations, commitments and writings with
respect to such subject matter. Notwithstanding any other provisions in this
Agreement to the contrary, in the event and to the extent that there shall be a
conflict between the provisions of this Agreement and the provisions of the
Employee Benefits and Compensation Allocation Agreement or the Tax Allocation
Agreement, the provisions of the Employee Benefits and Compensation Allocation

          1775 Logan Avenue
          Youngstown, Ohio 44505

          400 Research Parkway
          Meridien, Connecticut 06450
          Attention:  President

     SECTION 6.06   Dispute Resolution. Commercial Intertech and CUNO shall each
appoint two members from their managerial staffs to serve on the Dispute
Resolution Committee. The Dispute Resolution Committee shall meet at either
Commercial Intertech's or CUNO's offices, whichever is more appropriate in light
of the issue to be discussed, at such time as either party may demand in
writing, for the purpose of resolving any dispute arising, under this Agreement
or the Ancillary Agreements. If the Dispute Resolution Committee is unable to
resolve any dispute submitted to it by any party hereto within 30 days after
such submission, the Dispute Resolution Committee shall refer the issue to the
Chief Executive Officer of each of Commercial Intertech and CUNO for resolution.
If such officers are unable to resolve such dispute within fifteen days after
referral, such dispute shall be referred to binding arbitration as provided for
in SECTION 6.07. No such dispute shall be the subject of arbitration or other
formal proceeding between the parties hereto before being considered by the
Dispute Resolution Committee and the Chief Executive Officers of Commercial
Intertech and CUNO.

     SECTION 6.07   Binding Arbitration.

     (a) Any controversy, dispute or claim (whether lying in contract or tort)
between or among the parties arising out of or related to this Agreement or the
Ancillary Agreements shall, after the dispute resolution process set forth in
SECTION 6.06 has been completed, be submitted to arbitration in accordance with
this SECTION 6.07.

     (b) Each such controversy, dispute or claim submitted by a party to
arbitration shall be heard by an arbitration panel composed of three
arbitrators, in accordance with the following provisions.  Commercial Intertech
and CUNO shall each appoint one arbitrator within fifteen days after the matter
has been submitted to arbitration. The two arbitrators appointed by, or on
behalf of, the parties shall jointly appoint a third arbitrator, who shall act
as Chairman of the arbitration panel. If for any reason an arbitrator is unable
to perform his or her function, he or she shall be replaced and a substitute
shall be appointed in the same manner as the arbitrator replaced.

     (c) Except as otherwise stated herein, arbitration proceedings shall be
conducted in accordance with such rules as the parties mutually determine. In
any arbitration proceeding hereunder: (i) proceedings shall, unless otherwise
agreed by the parties, be held in Cleveland, Ohio; (ii) the arbitration panel
shall have no power to award punitive damages and shall be bound by all statutes
of limitation which would otherwise be applicable in a judicial action brought
by a party; and (iii) the decision of a majority of the arbitrators (or the
Chairman if there is no such majority) shall be final and binding on the parties
to this Agreement and shall

                                       21

 
be enforceable in any court of competent jurisdiction.  The parties hereby waive
any rights to appeal or to review of such decision by any court or tribunal and
also waive any objections to such enforcement.  THE PARTIES HEREBY AGREE TO
WAIVE ALL RIGHTS TO TRIAL BY JURY WITH RESPECT TO ANY CONTROVERSY, DISPUTE OR
CLAIM SUBMITTED TO ARBITRATION UNDER THIS AGREEMENT.

     (d) Notice preliminary to, in conjunction with, or incident to any
arbitration proceeding may be sent to the parties by registered or certified
mail (return receipt requested) at the address set forth in SECTION 6.05 and
personal service is hereby waived.  The arbitrators shall award recovery of all
costs and fees incurred in connection with the arbitration and the proceeding,
and obtaining any judgment related thereto, of each disputed matter (including,
reasonable attorney's fees and expenses and arbitrator's fees and expenses and
court costs, in each case, with respect to such disputed matter) to the party
that substantially prevails in the arbitration proceeding with respect to such
disputed matter.

     (e) No provision of this SECTION 6.07 shall limit the right of any party to
this Agreement to exercise self-help remedies such as set-off, or to obtain
provisional, equitable or ancillary remedies from a court of competent
jurisdiction before, after, or during the pendency of any arbitration or other
proceeding.  The exercise of a remedy does not waive the right of either party
to resort to arbitration.

     SECTION 6.08   Amendments.  This Agreement may not be modified or
amended except by an agreement in writing signed by the parties.

     SECTION 6.09   Successors and Assigns.  The rights under this Agreement
may not be assigned and duties may not be delegated by any party without the
written consent of the other parties, which consent shall not be unreasonably
withheld.  This Agreement and all of the provisions hereof shall be binding upon
and inure to the benefit of the parties and their respective successors and
permitted assigns.

     SECTION 6.10   Omitted.

     SECTION 6.11   No Third Party Beneficiaries. Except for the provisions of
ARTICLE IV relating to Indemnitees and SECTION 3.05(f) relating to directors and
officers, this Agreement is solely for the benefit of the parties hereto and
their respective Affiliates and should not be deemed to confer upon third
parties (including any employee of Commercial Intertech or CUNO or of any
Commercial Intertech Subsidiary or CUNO Subsidiary) any remedy, claim,
reimbursement, claim of action or other right in excess of those existing
without reference to this Agreement.

                                       22

 
     SECTION 6.12   Titles and Headings.  Titles and headings to sections
herein are inserted for convenience of reference only and are not intended to be
part of or to affect the meaning or interpretation of this Agreement.

     SECTION 6.13   Legal Enforceability.  Any provision of this Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof.  Any such
prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.  Without
prejudice to any rights or remedies otherwise available to any party hereto,
each party hereto acknowledges that damages would be an inadequate remedy for
any breach of the provisions of this Agreement and agrees that the obligations
of the parties hereunder shall be specifically enforceable.

     SECTION 6.14   No Waivers.  No failure by any party hereto to take any
action or assert any right hereunder shall be deemed to be a waiver of such
right in the event of the continuation or repetition of the circumstances giving
rise to such right, unless expressly waived in writing by the party against whom
the existence of such waiver is asserted.

     SECTION 6.15   Counterparts.  This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     SECTION 6.16   Performance.  Each party hereto shall cause to be
performed, and hereby guarantees the performance of, all actions, agreements and
obligations set forth herein to be performed by any Subsidiary or Affiliate of
such party.

                                       23

 
     IN WITNESS WHEREOF, the parties have caused this Agreement to be duly
executed as of the day and year first above written.
