    written notice of any such changes in prices or terms and conditions.
    Payments shall become due in accordance with invoicing as shipments are
    made.

E.  The DISTRIBUTOR may cancel orders, reduce quantities, revise specifications
    or extend schedules only by mutual agreement with CUNO, and in such event,
    the DISTRIBUTOR agrees to pay CUNO reasonable and proper cancellation
    charges which shall take into account expenses already incurred and
    commitments made by CUNO as well as any other loss incurred by CUNO by
    reason thereof.


F.  Ownership of each Product purchased by DISTRIBUTOR under this Agreement will
    pass to DISTRIBUTOR upon delivery to the carrier or to DISTRIBUTOR,
    whichever occurs first, but CUNO will retain a security interest, in, and

    may be revised from time to time by CUNO, in its sole discretion.

A.  Orders and inquiries concerning the Products listed on Schedule A received
    by CUNO directly from customers from the Market in the DISTRIBUTOR's
    Territory will customarily be referred to the DISTRIBUTOR.


 
 
B.  CUNO may make sales of specialty products directly to customers from the
    Market in the Territory but in such case, will pay to the DISTRIBUTOR a
    commission for work reasonably requested by CUNO in connection with such
    sale. Such commission shall be according to the then prevailing CUNO
    commission policy.


VII.  WARRANTY AND RETURNS


The following provisions shall apply to the return of Products by customers:


A.  Repair or Replacement. Products or parts may be returned to CUNO by the
    DISTRIBUTOR or his customer for repair or replacement if the defect is
    covered under CUNO's standard limited express warranty, which may be revised
    from time to time, provided, however, that the DISTRIBUTOR must give CUNO
    written notice thereof in advance of the return on CUNO's returned goods
    form. Thereafter, CUNO will provide the DISTRIBUTOR with shipping
    instructions, and the DISTRIBUTOR may then return the item in accordance
    with such instructions.


B.  Credit. CUNO will accept no returns for credit unless CUNO's written
    permission, in each case, has been given in advance. Only Products which are
    then (i) in good, merchantable condition, comparable to CUNO's prevailing
    standards, (ii) in CUNO's standard Product line, and (iii) in active
    demand, will be considered by CUNO for return or credit. In cases where CUNO
    gives its written permission for a specific return for credit, the credit
    given will be based upon prices prevailing at the time that the permission
    is granted or upon the originally invoiced price of the returned Product,
    whichever is lower, and subject in each case to deductions, determined by
    CUNO, for handling and for time and expense incurred in restoring goods to
    saleable condition.


C.  The DISTRIBUTOR is not authorized to extend to its customers any other
    warranty, whether express or implied, relating to the Products, other than
    the CUNO standard limited express warranty. The DISTRIBUTOR agrees to
    include in its provisions of sale to its customers CUNO's standard limited
    express warranty (and all exclusions of implied warranties and the
    limitations of liability). The DISTRIBUTOR agrees to indemnify and hold CUNO
    harmless from any claims or costs (including, but not limited to, actual
    attorneys' fees), damages and liabilities resulting from any warranty or
    representation not specifically authorized by CUNO in writing or by reason
    of the DISTRIBUTOR's failure to effectively disclaim any other express
    warranty or implied warranty or any claim for consequential damages.


D.  CUNO agrees to defend, indemnify and hold DISTRIBUTOR harmless for any
    claim, loss, suit, action or judgment brought against DISTRIBUTOR solely by
    virtue of an allegation that a Product is defective in design or
    manufacture

 
 
    and has thereby caused personal injury or property damage.


E.  DISTRIBUTOR agrees to indemnify and hold CUNO harmless for any claim, loss,
    suit, action or judgment, including attorneys' fees, brought against CUNO by
    virtue of or arising out of an alleged improper sale, application or
    servicing of Products by DISTRIBUTOR, or any other alleged improper or
    negligent action of DISTRIBUTOR, its employees, agents or assigns.


VIII.  DISTRIBUTOR MODIFICATIONS


The DISTRIBUTOR may not make modifications to Products sold to it by CUNO, 
except to the extent necessary to include CUNO authorized accessories parts. The
CUNO limited express warranty shall be null and void with respect to any 
Products by otherwise modified. All liability for unauthorized modifications to 
Products by the DISTRIBUTOR shall be borne by the DISTRIBUTOR, and the 
DISTRIBUTOR shall indemnify and hold CUNO harmless from any claims relating to 
said modification.


IX.  STOCK ADJUSTMENT POLICY


An initial stock adjustment without penalty and with written notice to CUNO
is allowed according to the prevailing CUNO policy on stock adjustment.


X.  CONFIDENTIAL INFORMATION


During the term of this Agreement, it may become appropriate for CUNO to submit
information to the DISTRIBUTOR which is proprietary and/or confidential
commercial or technical information that is not publicly available and that
should not be made available to others. With respect to any such information
submitted in writing and identified as "Proprietary" or "Confidential," it is
agreed that the DISTRIBUTOR will not disclose such information to others or use
such information except as contemplated herein, without prior written
authorization of CUNO. No such obligation shall apply to information which:(a)
is or becomes publicly available other than through breach of this provision; or
(b) was known to the DISTRIBUTOR at the time of disclosure, as demonstrated by
written records; or (c) later becomes known to the DISTRIBUTOR from another
source without restriction. Upon termination of this Agreement or any amendment
or renewal thereof for any reason, all information that is "Proprietary" or
"Confidential" shall be returned by the DISTRIBUTOR to CUNO immediate.

XI.  TRADEMARKS


During the term of this Agreement, DISTRIBUTOR is authorized to use CUNO's trade
name or any of CUNO's trademarks relating to the Products in a manner approved
by CUNO, but only for display purposes in connection with DISTRIBUTOR's
solicitation of orders for Products from customers in the Territory. DISTRIBUTOR
shall not use CUNO's trade name of any of its trademarks as part of
DISTRIBUTOR's trade or business name or in any other way which CUNO considers
misleading or objectionable. Upon termination, the DISTRIBUTOR agrees to
discontinue any previously approved use of CUNO trademarks, and to discontinue
indicating that it is associated in any manner with CUNO.

    previous acceptance by CUNO, except those Products which are proved to
    CUNO's satisfaction to be the subject of a binding order for shipment within
    30 days of termination received from a customer prior to the receipt by the
    DISTRIBUTOR of notice of termination. CUNO shall have no obligation or
    liability to the DISTRIBUTOR or its prospective customers in connection with
    any such cancellation. If CUNO accepts such an order and the Product is
    shipped, CUNO will arrange for the delivery and warranty service of the
    Product. The acceptance of orders from the DISTRIBUTOR or the continuous
    sale of Products to the DISTRIBUTOR or any other act after termination of
    this Agreement shall not be construed as a renewal of this Agreement for any

    order shall be on payment terms established by CUNO, including cash in
    advance.

B.  Upon termination of this Agreement or of any schedule hereto, the
    DISTRIBUTOR shall return to CUNO, upon CUNO's request and at CUNO's expense,

    policy manuals, service bulletins, parts cross-reference manuals, sales
    aids, such as filmstrips and recordings, and other publications of CUNO and
    its affiliates which the DISTRIBUTOR has on hand relating to Products.

C.  The DISTRIBUTOR shall be solely responsible for all commitments incurred or
    assumed by it during the term of this Agreement or hereafter, and CUNO shall
    not be held responsible in any manner therefor, irrespective of any
    suggestion or recommendation with respect thereto by CUNO or any of its
    employees or representatives unless CUNO has expressly agreed in writing to
    assume the responsibility.

D.  In the event of any termination of this Agreement, all obligations owed by
    the DISTRIBUTOR to CUNO shall become immediately due and payable on the
    effective date of termination whether otherwise then due or not (without
    presentment, demand, protest or notice of any kind, all of which are hereby
    waived by the DISTRIBUTOR); and CUNO may offset and deduct from any or all
    sums owed to the DISTRIBUTOR any or all sums owed by the DISTRIBUTOR,
    rendering to the DISTRIBUTOR the excess, if any.
 
E.  Neither CUNO nor the DISTRIBUTOR shall, by reason of the termination of the
    Agreement, be liable to the other for compensation, reimbursement, or
    damages either on account of present or prospective profits on sales or
    anticipated sales, or on account of expenditures, investments or commitments
    made in connection therewith or in connection with the establishment,
    development or maintenance of the business or goodwill of CUNO or the

 
    DISTRIBUTOR, or on account of any cause or thing whatsoever; provided,
    however, that such termination shall not affect the rights or liabilities of
    the parties with respect to Products previously sold hereunder or with
    respect to any indebtedness then owing by either party to the other.

F.  Upon termination of this Agreement by CUNO, the DISTRIBUTOR shall have the
    right to return Products, at the price at which DISTRIBUTOR purchased them,
    with no restocking charge. The Products must be in full case quantities, in
    the current CUNO price list, in the original packaging and in salable
    condition.

the underlying business relationship, including termination thereof and
including statutory claims, and which are not resolved between the parties
themselves, shall be submitted to binding arbitration in Hartford, Connecticut
before a single arbitrator in accordance with the Commercial Arbitration Rules
of the American Arbitration Association. Judgment upon the award of the
arbitrator may be entered in any court having jurisdiction thereof. Any and all
disputes shall be submitted to arbitration hereunder within one year from the
date the dispute first arose or shall be forever barred. Arbitration hereunder
shall be in lieu of all other remedies and procedures available to the parties,
provided that either party hereto may seek preliminary injunctive or other
interlocutory relief prior to the commencement or during such proceedings.

XV. MISCELLANEOUS

A.  All questions arising out of or related to the negotiation, preparation,
    revision, execution, delivery, performance or breach of this Agreement or
    any of its terms shall be governed by the laws of the State of Connecticut
    as applied to contracts wholly made and wholly to be performed within that
    State and without regard to that State's conflict-of-laws provisions.

    parties and not that of agent and principal or franchisor and franchisee.

    other transfer of all or substantially all of CUNO's business regardless of
    the form of such transaction.

    any documents incorporated by reference, constitutes the entire
    understanding between the parties respecting the sale to the DISTRIBUTOR and
    the purchase and distribution by the DISTRIBUTOR of the Products of CUNO.

BLANKET ORDERS

POLICY
    It is recognized that for various reasons, customers may wish to issue a
    single purchase order covering multiple purchases and shipments of Cuno
    standard products. It is the policy of Cuno to accept such orders.

TERMS & ACCEPTANCE
    Blanket Orders will be accepted subject to negotiated minimum release
    quantities. Blanket orders shall not extend beyond 12 months from the issue
    date of the Distributor Purchase Order.

BLANKET ORDER: SPECIAL PRODUCTS
    Provisions to be negotiated by Sales Manager. 

PRICING
    Quantity discounts on Standard Products reflect economies affected by
    manufacturing and shipping in one lot. Therefore, quantity discounts are
    granted on the basis of the quantity released for any given shipment.

RUSH ORDER CHARGES
    The following Rush Order adders will be charged: 
              Order required to ship with 48 hours of receipt
                                .....15% surcharge of order value 
              Order required to ship within 72 hours of receipt
                                ......5% surcharge of order value

    Special note: All time frame parameters are by business day (Monday through
    Friday) exclusive of weekends. By way of example, a 72-hour Rush Order being
    received on Friday, would provide for shipment up through the following
    Tuesday. Likewise, the service norm for a 24-hour Rush Order being received
    at 2:00 P.M. on a Friday afternoon would allow for shipment by Monday P.M.

RETURN GOODS POLICY
    Cuno Incorporated will authorize the return of goods shipped in error,
    ordered in error, defective goods, or goods for repair, subject to
    written approval and the following conditions:

GOODS SHIPPED IN ERROR
