         February 20th:   Revised forecast - no restriction
         March 20th:      90-day forecast within +/- 50% of February

forth in Schedule C are per part number and per shipment.

9.       Taxes and Duties. Prices are exclusive of certain taxes, duties,
brokerage or like charges imposed on Products after their delivery to Buyer and

Buyer's customers prior to the changes. Such upgrade kits may include hardware
and/or software. Buyer shall, at Buyer's expense, perform all labor to
implement the Mandatory Field Change Order, except in cases where a Mandatory
Field Change Order is required to make the Product(s) safe in compliance with
regulatory agency standards. Kentek shall reimburse Buyer for Buyer's travel
and labor cost for implementing such Mandatory Field Change Order in that
instance only. Kentek may, at its option, elect to execute such Mandatory
Changes at its own expense.

11.3     Enhancements. If, during the term of this Agreement, Kentek offers any
improvement, option, additional functionality or other enhancements to any
Product not available at the time this Agreement is signed (an "Enhancement"),
provided that such Enhancement is not exclusive to another customer, Kentek
will offer such Enhancement to Buyer at prices that do not exceed those charged
to any other customer of Kentek purchasing the same or lesser quantities of
such Enhancement on similar terms and conditions as those contained herein.

12.      Patent, Copyrights, Trademarks, and Trade Secrets Indemnity. Except as
provided below, Kentek, at its own expense, agrees to defend (without prejudice
to its sole option to settle) and hold Buyer harmless against any suit or
proceeding brought against Buyer alleging that any Product, or any Software
Product or any part thereof sold or licensed hereunder infringes any United
States patent, trademark, copyright or trade secret or other proprietary right
owned by others (an "Infringement Action"), provided Kentek is promptly
notified in writing, given all reasonable assistance it requires, (at Kentek's
expense) and permitted to direct the defense and/or settlement of such
Infringement Action.  Further, Kentek will pay in full any final non-appealable
judgment rendered in such Infringement Action by a court, or shall pay any
agreed upon settlement with respect to such Infringement Action, but shall not
be responsible for costs or settlements incurred without its consent. If
Buyer's use or sale of any such Product of Software Products is enjoined, or in
the event that Kentek desires to minimize its liabilities hereunder, Kentek
will, at its sole option and expense, (i) substitute other equally suitable
Product, or Software Product (ii) modify the Product or Software Product so
that it is no longer alleged to infringe, but delivers substantially equivalent
or better performance, (iii) obtain for Buyer the right to continue its use or
sale and (iv) if no other reasonably commercial option is available, grant to
Buyer credit for the Product or Software Product as depreciated and accept its
return. The depreciation shall be an equal amount per year over the lifetime of
the Product or Software Product for three years. The foregoing states the
entire liability of Kentek for Patent, copyright, trademark, trade secret or
other infringement. No indemnity shall apply to patent, copyright, trademark,
trade secret or other infringement liability to the extent directly arising
from any Product or Software Product made or modified to Buyer's specifications
or design, or with components or subassemblies supplied by Buyer, or a supplier
designated by Buyer, including (without limitation) copyright, patent
infringement or other claims related to images produced in accordance with
Buyer's specifications or based on Buyer's

                                       11
<PAGE>   12
modification of Product or Software Product or programming. The foregoing
indemnity shall not apply and Buyer agrees to indemnify Kentek in a manner
fully equivalent to the foregoing indemnity with respect to any claim made, or
any suit or proceeding brought against Kentek, in which and to the extent that
the alleged infringement arises from the combination of any Product or Software
Product with any equipment, subassemblies or components not supplied by Kentek
or its operation or use with apparatus, data or programs not furnished by
Kentek, except for the operating system of the host computer or if the alleged
infringement arises from any modification of any Product or Software Product or
from the printing of an image produced or modified, in accordance with the
specifications of Buyer or any Customer.

Section 16 are broken by Buyer or Kentek, its successors or any sublicensees of
any Software Products, the license granted to any breaching party (but not the

Liability, Etc.

18.1     Product Warranties. Kentek warrants that each Product sold under this
Agreement shall be free from defects in material and workmanship under normal
use and service, and that such Products will meet the specifications set forth
on Schedule D (as the same may be added to, modified, or amended from time to
time).

         Warranties shall apply for the time periods designated below:

         Model K30, K30D, K31, K31D and K40D engines and related models for two
         (2) years from date of shipment.

         Accessories and Spare Parts for one hundred eighty (180) days from
         date of shipment.

         Consumables for average rated yield.

         All warranties are on Products used within specified duty cycle and
         Product Specifications.

Normal use and service does not include any abuse, misuse, transportation
damage, alteration or depletion after delivery hereunder. If the defect can be
isolated to any particular Parts, the warranties set forth herein cover such
Parts only (whether installed in a Printer or not), and in no event shall
Kentek be liable for labor or installation of such Parts.  In the event of a
warranty claim under this Section 18, at Kentek's election, Buyer shall dispose
of or ship the defective Parts, or if the defect cannot be isolated to any
particular Parts, the defective Printer, in each case uninsured (at Kentek's
risk) but properly packaged, with freight collect, to such facility as Kentek
shall indicate to Buyer from time to time. At its option, Kentek shall repair
or replace the defective Parts or Printer, as the case may be, and shall ship
it, with freight and insurance collect, back to Buyer within 30 days of
Kentek's receipt of the same.  The procedure for claims under this Warranty is
set forth in Schedule J under "Defective Material Return Procedure and Product
Warranties."

18.2     Warranties Do Not Apply To Buyer Components, Modifications, Etc. The
warranties set forth in Section 18.1 do not extend to components or
subassemblies supplied by Buyer or suppliers designated by Buyer or to
modifications of any Product which have been made by or at the request of Buyer
or any Customer, or to units of Products which fail or are damaged after
delivery hereunder due to improper shipment, handling, storage, operation, use
or maintenance in a manner or environment or with parts, accessories, supplies
or consumables not conforming to published instructions or specifications of
Kentek at the time of delivery of such Product, or due to service or
maintenance by persons not qualified to perform the same. Use of any consumable
not specifically supplied by or approved in writing by Kentek shall constitute
a modification of Product and shall specifically void any and all warranties
for both printer and consumable supply products. Kentek shall have no liability
or responsibility with respect to any warranties provided by Buyer or any third
person.

18.3     Disclaimer; Limitation of Liability. THE WARRANTIES SET FORTH IN
SECTION 18.1 AND THE OBLIGATIONS AND LIABILITIES SET FORTH IN SECTION 18.1 AND
IN SECTIONS 10 AND 12 ARE IN LIEU OF ALL OTHER WARRANTIES RELATING TO ANY

WHETHER EXPRESS OR IMPLIED BY STATUTE OR COMMON LAW OR OTHERWISE HOWSOEVER, ARE
HEREBY EXPRESSLY DISCLAIMED.

         Without limiting the foregoing, Buyer's exclusive remedy and Kentek's
entire obligation and liability in contract, tort or otherwise for any breach
of warranty of any Products, Software Products or Manuals and Documentation, or
the failure of any Products or Software Products to meet the specifications set
forth in Schedule D, is the repair or exchange of any defective Products
covered by the foregoing warranties in the manner and within the time frames
set forth.

prejudice to its sole option to settle) and defend Buyer from and against all
liability demands, claims loss, cost damage and expense for property damage,
death and personal injury arising out of or relating to the Products sold to
Buyer and performance of this order; provided, however, Buyer shall be liable
to the extent of its own negligence. At Buyer's request, Kentek will furnish
certificates of insurance evidencing liability insurance which includes but is
not limited to worker's compensation, general liability, property damage
liability, and product liability. Kentek agrees to defend or settle, at its
sole expense, all suits or proceedings arising out of any suits or threats of
suit provided Buyer gives Kentek prompt written notice of all suits or threats
of suit and other such claims. Buyer may be afforded the opportunity to join
and fully participate in, at its own expense, the defense of such proceedings.

19.      Product Reliability. If any Product does not function at the mean time

course of action, if any, would be appropriate to remedy such failure.

non-Affiliate subcontractors, governmental laws, regulations or orders. Agreed
upon delivery schedules and the term of this Agreement shall be considered
extended by a period of time equal to the time lost because of any delay

excusable under this Section 20, it shall give prompt written notice thereof to
the other party including its best estimate of the expected duration of such
delay.

                 body of the United States or any political subdivision thereof
                 or any other relevant jurisdiction; provided however, that the
                 party from whom disclosure is sought shall, if permitted,
                 first have given notice to the other and made a reasonable
                 effort to obtain a protective order requiring that the
                 Information and/or documents so disclosed are used only for
                 the purpose for which the order was issued;

         (ii)    otherwise required by law, statute, ordinance, rule,

                 knowledge of a substantial part of the industry, through no
                 fault of the Recipient; or

         (vi)    is disclosed by the Discloser to a third party without a duty
                 of confidentiality on the third party.

of its obligations under this Section 21 would cause irreparable harm to the
other, and that the other shall be entitled, in addition to all other remedies

obligations set forth and envisioned by this Agreement. Each party indemnifies
and holds the other harmless for breach of the warranties and representations
contained in this Section 29.

loss or damage or if such loss or damages arise out of the termination of this
Agreement. No action arising out of this Agreement, regardless of form, may be
brought more than two years after the cause of action has arisen.

31.      Severability. If any provision of this Agreement, or the application
hereof to any person or circumstance, for any reason or to any extent, shall be
found by any court of competent jurisdiction to be illegal, invalid or
unenforceable, the remainder of this Agreement and the application of that
provision to other persons or circumstances shall not be affected, but rather
shall be enforced to the extent permitted by law so long as it still expresses
the intent of the parties. If the intent of the parties cannot hereby be
preserved, the parties agree to enter into a legal, valid and enforceable
substitute agreement which will achieve the objectives of this Agreement as it
is written, or renegotiate the affected portions of this Agreement to the same
end.

                 No failure to exercise, or, delay in exercising, on the part
of either party, any right, power or privilege hereunder shall operate as a
waiver thereof, or will any single or partial exercise of any right, power or
privilege hereunder preclude the further exercise of the same right or the
exercise of any other right hereunder.

                 Nothing expressed or implied in this Agreement is intended or
shall be construed to confer upon or give to any person other than the parties
hereto, and their respective permitted successors and permitted assigns, any
rights or remedies under or by reason of this Agreement. This Agreement is not
assignable in whole or in part by either party without the prior written
consent of the other, except that either party may, without such consent,
assign this Agreement and its rights and obligations hereunder to any successor
to its business or to the ownership of all or substantially all of its stock or
assets that assumes such parties' obligations hereunder. Each party hereto is
and at all times shall be independent and nothing contained in this Agreement
shall be construed as constituting either party, a partner, co-venturer,
employee or agent of the other.

                 This Agreement may be executed in counterparts, each of which
shall be deemed an original but all of which shall constitute but one
Agreement.

accordance with the laws of the State of Colorado.  Any action or proceeding
brought to enforce obligations contained in this Agreement may be brought in

and agree to submit to the jurisdiction of any of such courts.

In the event of fluctuations in the Yen/Dollar "Bank Exchange Rate," the prices
listed in Schedules A and C shall be automatically adjusted in the following
manner. These adjustments will be made at the time of Purchase Order Placement.
After an order is placed, there will be no further adjustment for additional
"Bank Exchange Rate" fluctuations. The "Bank Exchange Rate" shall be determined
by the previous month's average Yen/Dollar rate calculated from the fifteenth
day of the prior month to the fourteenth day of the current month of selling
rates between the U.S. Dollar and the Japanese Yen as quoted daily in The Wall
Street Journal exchange rate tables of "New York Foreign Exchange Selling
Rates".

If the previous month's average is outside the base rate range [ ]-[ ] Yen per
Dollar, then Kentek shall advise the Customer of the price adjustment for all
purchase orders received after the fourteenth day of the current month. Such
price adjustments shall be in accordance with the attached schedule. Outside of
the ranges indicated, Kentek will adjust accordingly.

                KENTEK INFORMATION SYSTEMS, INC.


                        PRODUCT WARRANTY




Kentek warrants that the Printer Product delivered shall be free from defects
in material and workmanship, under normal use and service, and that any part or
parts found defective within:

     a.   180 days from original shipping date for spare parts
     b.   180 days from original shipping date for high capacity feeders and
          stackers
     c.   2 years from original shipping date for printer engine (when operated
          within specified duty cycle);*

shall be repaired by the Reseller with parts supplied by Kentek or replaced by
Kentek at Kentek's shipping point.

The Reseller will segregate and make available to Kentek at a central location
those parts found defective with a list price exceeding $50.00. The Reseller
will return defective parts freight prepaid. This Product Warranty is
applicable only if the Product has had normal utilization within the
specification, and has been maintained in accordance with recommended
procedures. Any and all other costs in the implementation of this warranty
shall be the responsibility of the Reseller.

The warranty set forth in this Article does not extend to altered units of the
Product or to units of the Product which fail or are damaged after delivery to
the Reseller due to the shipment, handling, storage, operation, use or
maintenance in a manner or environment not conforming to any published
instructions and specifications of Kentek at the time of delivery. Use of any
consumable not specifically supplied by or approved in writing by Kentek shall
constitute a modification of Product and shall void any and all warranties for
both printer and consumable supply product.

* Any repair or replacement of any portion or part of the printer engine
(excluding Consumables, Software, and Accessories) does not decrease or extend
the original two-year warranty period.

                 KENTEK INFORMATION SYSTEMS INC.

                  CONSUMABLE WARRANTY PROCEDURE



The Kentek product warranty is contained in the Agreement between Kentek and
the Reseller. There are two parts to the warranty:

a.     Defects due to material and workmanship/out of box/mechanical warranty,
       and;

b.     failure to meet the average specified yield.

The warranty period is ninety (90) days from date of shipment to the Reseller.

Kentek's published specification yields are "average" and the warranty is
measured against the average yield for each type of consumable. If the rated
yield of any consumable is 400,000 prints and that consumable produces prints
within specification at the rated life then it is considered to have reached
its specified life. For example, if the customer has four K30 cleaners and two
make 425,000 prints and two make 375,000 prints, then no warranty credit is
applicable as the average is the specified 400,000.

In the event a customer returns consumable item(s) short of average life, the
customer should be given a credit only for the unused portion; i.e., 325,000
prints/400,000 average yield x unit selling price.

Kentek will work with the Reseller to provide credits where the population of
supplies does not meet the average life specified. Credits (or replacement
units) must be provided to the customer by the Reseller.

At Kentek's option, the Reseller will segregate consumables found defective and
return the defective consumables to Kentek freight prepaid. A Kentek Consumable
Warranty Return Form (sample attached) is required for each consumable being
returned for warranty evaluation.

This product warranty is applicable only if the product has had normal
utilization within specification and returned in a protective shipping
container. Toner cartridges must always be removed from Developers, and
Developers must be resealed prior to shipment. Should the defective consumable
be received damaged due to unsafe packaging warranty consideration will become
void.

                     DEFECTIVE MATERIAL RETURN PROCEDURES



The customer must first contact Kentek corporate headquarter's "Customer
Service Department" requesting a "Return Material Authorization" (RMA) number.
Kentek's Customer Service Department will collect the necessary data from the
customer to process the return of material accordingly.

The assigned RMA number must be referenced on the outside of the shipping
container. Return Material Tags are to be used by the customer when returning
defective parts either Under Warranty or for Exchange to Kentek corporate
headquarters, freight prepaid.

Repairs will be made or a replacement part will be sent to the customer within
30 days from receipt of defective part.

Warranty Items

If the returned defective item under warranty tested is found to be operational
(not defective), Kentek will notify the customer of our findings and a charge
for Kentek's testing and evaluation time will be billed back to the customer at
$75 per hour minimum of two (2) hours.

Exchange Program

Kentek has identified a selected list of material such as printed circuit
boards and power supply units that can be exchanged for a repaired and tested
replacement with a 90-day warranty given by Kentek.

The procedure to return defective items under our Exchange Program is the same
as the procedure for returning defective items under warranty as stated above.

                          KENTEK'S TRAINING PROGRAM

(6) students at no cost. The class will be held at Kentek corporate
headquarters. Any additional training requested by the customer will be offered
at a "most favored status" price.

In the event the customer requests the training class to be held anywhere other
than Kentek corporate headquarters, the customer will reimburse Kentek for all
travel and living expenses incurred by our training personnel during the
course.

The rates for additional training courses, if required, are included as a part
of this Schedule.

The rates for field service support from Kentek to resolve a problem at the

The training session will be a 3-day course and classes will be a standard
eight (8) hour day.

Class size is limited to six (6) students. In order to provide the most
effective possible training, we urge a minimum of three printers be made
available to the students.

Class subjects will consist of:

- Operational overview
- Component/assembly layout
- Xerographic process
- IGS & PCL block diagram of operations
- Communication theory RS 232, 422, Centronics (Host Connections)
- Diagnostics ... how they work and how to use them
- Problem/failure determination (flow chart)
- TAGS (Troubleshooting Analysis Guide) familiarization

Field Service manuals are available for each student consisting of:

- Installation/operational manual 
- Maintenance manual 
- Removal/replacement procedure 
- Self diagnostic test procedure 
- Troubleshooting 
- Electrical adjustments

- Technical bulletins

Special training material such as schematics, diagrams and technical data will
be issued to each student.

Troubleshooting time will be scheduled to allow the students to perform failure
analysis on the printer. Kentek parts are sold as assemblies, not components,
so this class will teach each student to repair printers down to the assembly
level.

                              Dated April 16, 1997
================================================================================

         WHEREAS, Tally and Kentek have entered into an agreement entitled
"Purchase Agreement," dated April 22, 1995 ("Agreement"); and

         WHEREAS, the parties now desire to amend the Agreement to change
certain terms and conditions of the sale and purchase of Products; and

         WHEREAS, the Agreement would expire unless extended by written
agreement of the parties;

         NOW THEREFORE, in consideration of the covenants and agreements herein
contained, SNPS and Kentek hereby agree as follow:

         1.      All capitalized terms not defined in this Amendment shall have
                 the meaning ascribed thereto in the Agreement.

         2.      Section 3.2 Term of Agreement, shall be amended to read "The
                 term of this Agreement shall commence upon the date hereof and
                 shall continue for twelve (12) months from such date (April
                 16, 1998), unless earlier terminated or extended by written
                 agreement of the parties (the "Term").

         3.      Section 13.3 End-of-Life Parts Purchasing, shall be amended to
                 read "Buyer may purchase spare parts from Kentek to provide
                 service to its customers. In the event Buyer or Kentek

                 purchased over a period of six months is less than 200
                 printers per year activating an End-of-Life condition, then
                 Kentek agrees to allow Buyer to purchase Parts and Consumables
                 at the new category (non-OEM designation) current prices for a
                 period of up to five (5) years for the purpose of supporting
                 Buyer's installed base.
