WHEREAS, as provided in the Assets Purchase Agreement, 3M desires to appoint
KNOGO, and KNOGO wishes to accept appointment, as a nonexclusive distributor of
3M's Library Security Systems and related products in the Market defined below,
pursuant to the terms of this Agreement;

NOW, THEREFORE, in consideration of the foregoing representations, and of the
following mutual and reciprocal promises and agreements, the parties state and
agree as follows:

1.   SCOPE OF AGREEMENT

     A. This Agreement defines the relationship between 3M and KNOGO with
respect to KNOGO's purchase and resale of the 3M Library Systems Products
identified in Exhibit A, which is attached and made part of this Agreement
(collectively, the "PRODUCTS"). New, additional or replacement products offered
by 3M for sale to its library customers shall be added to this Distribution
Agreement upon mutual written agreement of the parties, upon specific terms
negotiated in good faith and substantially similar to the terms of this
Agreement.

     B. The geographic market covered by this Agreement is the United States,
Canada and Puerto Rico (the "Market"). Under no circumstances shall KNOGO either
directly or indirectly advertise, promote or sell the PRODUCTS outside the
Market, or assist any other person to do so. If KNOGO subsequently learns that a
customer within the Market is selling PRODUCTS outside of the Market, KNOGO
agrees to immediately cease selling PRODUCTS to that customer.

     C. 3M does and will continue to sell the PRODUCTS directly and indirectly
through distributors, sales agents, buying consortia and others in the Market.

2.   3M'S OBLIGATIONS TO KNOGO.

     3M agrees to:

     A. Sell or license (as appropriate) PRODUCTS to KNOGO under the terms of
this Agreement and to use all reasonable efforts to promptly fill KNOGO's orders
for PRODUCTS. 3M will license the data transfer protocol and interface software
developed by 3M for use with 3M's Patron SelfCheck System to KNOGO at no charge
during the term of this Agreement.

     B. Make available to KNOGO without charge the services of a 3M sales
representative knowledgeable of the PRODUCTS who will provide PRODUCT
information and sales and s marketing training and support for KNOGO'S sales
representatives, as well as assisting KNOGO's specific customer presentations
and proposals.

     C. Provide KNOGO at no charge reasonable quantities of literature,
brochures, presentation materials and other like marketing materials that 3M
will prepare from time to time for, the purpose of assisting KNOGO to introduce
and promote the PRODUCTS.

     D. Provide without charge to KNOGO and its designated employees or agents
technical training and certification as to the operation of the PRODUCTS.

     E. Provide to KNOGO's customers installation and service of PRODUCTS;
except as provided in paragraph 3(B) below with respect to first year service on
certain PRODUCTS, all service charges will be billed directly by 3M to end
customers.

     F. For PRODUCTS sold by KNOGO, provide satisfactory evidence of the
installation at end customer locations.


3.   KNOGO'S OBLIGATIONS TO 3M.

     KNOGO agrees:

     A. To vigorously and enthusiastically promote the sale of the PRODUCTS
through every lawful and proper means, devoting through its sales force at least
the same level of energy and resources that KNOGO devoted to the sale of its own
library security systems and products prior to this Agreement;

     B. Throughout the term of this Agreement, KNOGO shall not sell or promote
to library customers any other library security systems products, accessories or
services which compete with or substitute for the use of the PRODUCTS. Within
five (5) days after the Effective Date, the parties, through their respective
sales management, shall prepare a Transition Sales Plan the provides the details
by which KNOGO and 3M will cooperate in the promotion and sale of PRODUCTS and,
whenever possible with respect to any pending but unbilled KNOGO orders, the
substitution of comparable 3M products for KNOGO's library security systems,
products, accessories, and services. Specifically, but without limitation, the
Transition Sales Plan shall provide as follows:

     (i) With respect to Knogo hardware and library security systems
accessories, other than its patron self-check product (the "Express"), KNOGO
shall use all reasonable efforts to persuade its customers, and any prospective
customers to whom KNOGO has offered to sell KNOGO products, to accept the 3M
PRODUCTS in every case in which the KNOGO products have not been delivered and
installed as of the date of this Agreement. This includes specifically those of
KNOGO's products for which it has received a purchase order, contract, or notice
of award under a formal or informal bidding process, as well as those case in
which KNOGO has made proposals or offers to sell its library products, excepting
only the immediate obligation to supply the Dallas Public Library. KNOGO shall
invite 3M to participate in its efforts, and the parties shall jointly make
sales calls and presentations to customers to attempt to persuade the customer
to accept comparable 3M PRODUCTS. If despite the cooperative and diligent
efforts of the parties a customer to whom KNOGO is contractually obligated
demands KNOGO products, then KNOGO may fulfill its contractual obligations by
supplying KNOGO products, but only to the extent of the number and type of KNOGO
products it is contractually required to supply. For those accounts who agree to
accept 3M PRODUCTS in place of KNOGO's products, KNOGO agrees to purchase from
3M the PRODUCTS at the prices stated in Exhibit A. KNOGO understands and agrees
that it will fulfill its obligations hereunder even though, in some cases, its
cost for the PRODUCTS paid to 3M may be lower than its bid or contract price at
which KNOGO has offered to sell its products to KNOGO's customer.

     (ii) With respect to any sales, consignments, trials, or offers to sell
KNOGO Express self-check units, KNOGO agrees that KNOGO will not sell, but will
use all of its reasonable efforts to at its own cost remove and retake
possession of and destroy all KNOGO Express units and any related software or
accessories, except for those which have been shipped, installed and billed to
the following specific end customers: Paso Robles, Salt Lake City Public
Library, Vancouver Public Library, U.C. Davis, Alhambra Public Library, George
Mason University, Springfield Green City., Addison Public Library, Palmdale City
Library, Ventura County, Cleveland Heights, SUNY-New Paltz, and Newport Beach
("Installed Expresses"). With respect to the Installed Expresses, KNOGO and 3M
shall cooperate to persuade such customers, whenever possible through the
reasonable efforts of 3M and KNOGO, to trade Installed Expresses for 3M's
Self-Check PRODUCTS. 3M will bear the cost of trading out Installed Expresses.

This paragraph is in addition to, and not in conflict with or limitation of, the
KNOGO's obligations under paragraph 5.4 of the Assets Purchase Agreement.

     C. To license 3M software PRODUCTS in accordance with the License Agreement
attached as Exhibit B and made part of this Agreement. KNOGO shall present and
use its best efforts to ensure that all of its customers abide by the terms of
that Agreement.

     D. KNOGO shall provide financial information reasonably requested by 3M or
its credit provider and will make payment to 3M within the agreed credit terms.
KNOGO agrees not to make deductions from invoices until a credit memorandum
authorizing the deduction is issued by 3M.

     E. To hold in confidence and not disclose to others 3M's confidential
marketing plans, promotional programs, planned product introductions, pricing,
or other 3M confidential information without 3M's prior written approval.

     F. To not disparage PRODUCTS or cast PRODUCTS in an unfavorable light, and
KNOGO will not misrepresent, either directly or by omission, the capabilities,
qualities or characteristics of PRODUCTS

     G. To use 3M's trademarks and tradenames (e.g., "3M," "Patron Self Check")
in a manner that distinguishes the 3M mark, does not imply that KNOGO is a part
of or owned by 3M, and otherwise as 3M directs. KNOGO is encouraged to obtain
3M's approval of advertising z containing any 3M trademark prior to publication.
Upon expiration or termination of this Agreement, KNOGO agrees to remove and
discontinue the use of any 3M trademark.

4.   PRICES AND CONDITIONS OF SALE.

     A. PRICES. The price of PRODUCTS and other terms and conditions of sale
(including KNOGO discounts, shipping, and minimum order requirements) are as
stated in Exhibit A to this Agreement. Some of the PRODUCTS include as part of
the price thereof an amount attributable to the provision of service during the
first twelve months after installation. KNOGO shall use its commercially
reasonable efforts to persuade the customer to purchase a service contract with
3M. z This amount shall be included in KNOGO's PRODUCT price as shown in the
Annual Service Agreement column of Exhibit A, and KNOGO agrees to pay this
amount, even if the end customer elects to not purchase a service contract.
KNOGO is free to sell the PRODUCTS with or without a service contract, however.
After the first year after installation, all sales, billing and collection with
respect to service contracts shall be handled directly between 3M and the end
customer.

     B. PRICE CHANGES. Prices may be increased and other conditions of sale may
be changed by 3M at any time upon thirty (30) days' prior written notice to
KNOGO, but the change will not affect any order properly accepted by 3M and
requesting immediate shipment before the effective date of the change. 3M may
decrease prices without notice and KNOGO will be invoiced at the price in effect
on the date of shipment. 3M may periodically offer new PRODUCT or introductory
offers, on which KNOGO discounts may not in some cases be applied; provided,
however, that such discounts shall be applied if and to the extent such PRODUCTS
are offered for sale by 3M's direct sales force to end customers at prices less
than KNOGO's purchase price.

     C. SPECIAL CONTRACT PRICING. 3M recognizes that KNOGO may place bids for
the supply of PRODUCTS over a period of time. Upon the prior written approval of
3M's National Sales Manager, 3M will commit to hold its published prices firm
for a period not to exceed six (6) months from the date of approval; provided,
however, that if KNOGO's bid is accepted, KNOGO shall promptly provide to 3M
Customer Service a complete copy of KNOGO's bid and satisfactory evidence that
the bid has been accepted.

     D. TAXES. Prices listed on 3M's price pages do not include sales, use,
excise, or similar taxes. The amount of any present, retroactive, or future
sales, use, excise or similar tax applicable to KNOGO's purchase of PRODUCTS
will be added to the 3M invoice and paid by KNOGO unless KNOGO provides 3M with
tax exemption certificates acceptable to the appropriate taxing authorities.

     E. PURCHASE ORDERS. . KNOGO will order PRODUCTS only by purchase orders
submitted to 3M. Acceptance of any orders placed by KNOGO, either by written
acknowledgment or by shipment of PRODUCTS, does not constitute acceptance by 3M
of any of the terms and conditions contained in such orders, except the
identification and quantity of PRODUCTS ordered. All orders are governed by the
provisions of this Agreement.

     F. ALLOCATION. If any PRODUCT is in short supply, 3M may allocate the
available supply among its customers in the manner that 3M considers most
equitable, but will assign to KNOGO the highest priority among 3M's customers
who buy for purposes of resale.

     G. CREDIT. 3M may change or limit the amount or duration of credit to be
allowed KNOGO. 3M may cancel any orders accepted by 3M or delay the shipment of
the order, if KNOGO fails to meet payment schedule or other credit or financial
requirements reasonably established by 3M.

     H. PRODUCT DISCONTINUANCE. 3M may discontinue the production or sale of any
PRODUCT at any time during the term of this Agreement. KNOGO may continue to
purchase from 3M and resell any discontinued PRODUCTS for so long as 3M
continues to have such PRODUCT available.

5.   TERM; TERMINATION.

     A. The Agreement term begins on the date it is signed by both KNOGO and 3M
("Effective Date").

     B. The Initial Term shall be three (3) years from the Effective Date.
Thereafter, this Agreement shall continue automatically for consecutive one-year
terms ("Renewal Terms") until terminated. Either party may terminate the
Agreement only as provided below.

     C. During the Initial Term, neither party may terminate this Agreement
except for a substantial breach by the other party of its material obligations
hereunder, which breach is not or cannot be cured within a reasonable time (not
to exceed 30 days) after notice from the complaining party. Any notice hereunder
shall specify in detail all causes of alleged nonperformance and the corrective
actions sought by the complaining party. If all of the causes therefor are not
cured to the reasonable satisfaction of the complaining party within the same
cure period as above, then this Agreement shall terminate effective upon the
expiration of the cure period. An example, without limitation, of a "material"
obligation is KNOGO's efforts to promote PRODUCTS as stated in paragraph 3(A)
above.

     D. The continued relationship between 3M and KNOGO beyond the Initial Term
is based upon mutual expectation of growing sales volume, profits and other
advantages, as well as the fulfillment of mutual responsibilities. If after the
Initial Term either party wishes for its own reasons to discontinue this
Agreement, or if it believes the expected advantages of this Agreement s have
not been or cannot be reali7Atl, or that the responsibilities or this
relationship are not being fulfilled either party may terminate this
relationship by giving the other party advance written notice at least ninety
(90) days prior to the expiration of the then current Initial or Renewal Term of
its intent to terminate by registered mail or personal delivery. Either party
may exercise its right of termination without having to prove or possess "good
cause". Termination shall then become effective on the ninetieth day following
such notice, or the expiration of the current Initial or Renewal Term, whichever
first occurs.

     E. 3M is not obligated to repurchase PRODUCTS in KNOGO's stock upon
termination of this Agreement. KNOGO may sell, in accordance with the terms of
this Agreement, those PRODUCTS in its inventory on the date of termination for
which 3M has not exercised its option to repurchase.

     F. During the period between giving the notice of termination and the
effective date of termination, all PRODUCTS will be delivered to KNOGO on a cash
with order basis. Upon {, termination of this Agreement by either party, 3M and
KNOGO shall cooperate to see that all end customer needs are served and all
orders are filled.

6.   WARRANTY AND LIMITATION OF REMEDIES: DISCLAIMER.

     A. 3M warrants to KNOGO that PRODUCTS are free of defects in material and
manufacture at the time of shipment. Individual PRODUCTS may have additional or
different warranties as stated on PRODUCT packaging, package inserts, price
pages or literature. If any PRODUCT is proven to be defective in material or
manufacture during the applicable warranty period, 3M's entire liability and
KNOGO's exclusive remedy will be, at 3M's option, 1) repair of ~, PRODUCT, 2)
replacement of PRODUCT or 3) refund of the purchase price paid by KNOGO for each
defective PRODUCT, within a reasonable time after written notification of the
defect and return of the defective PRODUCT to 3M.

     B. THE WARRANTY STATED ABOVE IS MADE IN LIEU OF ALL OTHER WARRANTIES,
EXPRESS OR IMPLIED, INCLUDING BUT NO LIMITED TO THE IMPLIED WARRANTY OF
MERCHANTABILITY, THE IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, ANY
IMPLIED WARRANTY ARISING OUT OF A COURSE OF DEALING OR OF PERFORMANCE, CUSTOM OR
USAGE OF TRADE, EXCEPT OF TITLE AND AGAINST PATENT INFRINGEMENT.

     C. If KNOGO offers express implied warranties and limited remedies which
differ from those stated above, KNOGO agrees to assume full responsibility for
all liability, loss, cost, and expense arising out of, or in connection with,
the different warranties and/or remedies offered by KNOGO.

7.   LIMITATION OF LIABILITIES; TIME LIMIT FOR FILING ACTION.

     A. NEITHER PARTY WILL UNDER ANY CIRCUMSTANCES BE LIABLE TO THE OTHER PARTY
FOR DAMAGES OF ANY KIND, INCLUDING WITHOUT LIMITATION, DIRECT, INDIRECT,
INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO,
LOSS OF PROFITS, REVENUE OR BUSINESS) RESULTING FROM OR IN ANY WAY RELATED TO
PRODUCTS, ANY OF KNOGO'S PURCHASE ORDERS, THIS AGREEMENT OR THE TERMINATION OF
THIS AGREEMENT. This limitation applies regardless of whether the damages or
other relief are sought based on breach of warranty, breach of contract,
negligence, strict liability in tort or any other legal or equitable theory.
This limitation does not apply to direct damages caused by breach of a material
obligation under this Agreement (except breach of warranty) or to claims for
personal injury by a third party.

     B. Any action for breach of warranty or otherwise in any way arising under
or related to this Agreement must be commenced within one (1) year after KNOGO
becomes aware of the breach.

8.   EXCUSED PERFORMANCE.

     Except for KNOGO's obligation to make payment to 3M, neither party will be
liable for any failure to perform its obligations under this Agreement if due to
any cause beyond the i reasonable control of the non-performing party.

9.   RELATIONSHIP OF THE PARTIES.

     The relationship established between 3M and KNOGO by this Agreement is that
of a vendor to its vendee. KNOGO is not an agent or franchisee of 3M and has no
authority to bind 3M, transact any business in 3M's name or on its behalf in any
manner, or make any promises or representations on behalf of 3M. KNOGO agrees to
represent itself only as an independent business that is an "authorized 3M

(b) the sale or transfer of the entire business or substantially all the assets
of KNOGO. Any assignment or transfer of this Agreement or any interest in this
Agreement, without 3M's prior written consent is void and cause for termination
of this Agreement. Nothing in this Agreement will be construed to grant any
person or entity not a party to this Agreement any rights or powers whatsoever.
No person or entity will be a third party beneficiary of this Agreement.

11.  NO WAIVER.

     Any failure or delay by either party in exercising any right or remedy in
