           whether this paragraph restrains Seller from accepting such
           business.

            information.

      17.1. DELAYING CAUSES
            Seller shall not be liable for any delay in performance under this

            Seller's control and without Seller's fault or negligence
            (collectively "delaying cause").  Seller shall, in the event of a
            delaying cause, immediately give notice to HP of that cause.
      17.2. HP'S RIGHTS
            In the event of a delaying cause, HP may elect in its sole
            discretion to suspend the Agreement in whole or in part for the

            part thereof.

18.  DEFAULT
      18.1. HP'S RECOURSE
            If the Seller fails to perform or breaches any material provision
            of this Agreement, HP provides written notice to the Seller of such
            failure to perform or breach, and Seller fails to provide a written
            response within ten (10) days from HP's written notice, and fails
            to cure the failure to perform or breach within thirty (30) days
            from the receipt of such written notice, HP may, except as
            otherwise prohibited by the United States Bankruptcy laws,
            terminate the whole or any part of this Agreement.  Further, if
            voluntary bankruptcy proceedings are instituted against Seller and
            not discharged within sixty (60) days, HP may, except as otherwise

            In the event that HP terminates this Agreement in whole or in part,
            as provided in this section on Default, HP may procure, upon such
            terms and in such manner as HP deems appropriate, services similar
            to the services as to which this Agreement is terminated.  Seller
            shall reimburse HP upon demand for all additional costs incurred by
            HP in purchasing such similar services.

                                   ADDENDUM B
                              PROCESS DEFINITIONS

1.   DELIVERY AND HANDLING OF END USER TECHNICAL ASSISTANCE CALLS
      1.1. End users who are calling for support on the target products
           will call 1 (800) 724-6631.  This phone number will be owned by HP,
           but will ring at the Seller's location.  HP will incur all phone
           company service tariffs associated with (800) 724-6631.
      1.2. The Seller's Voice Response Unit (VRU) will route the calls
           as defined by HP.
      1.3. The customer's product registration will be verified by the
           Seller.  If the customer's product is not registered, the Technician
           will perform product registration before technical assistance is
           provided.
      1.4. The Seller Technician will answer the customer call based on
           information in the Seller knowledge base or in HP product
           documentation.  If information pertaining to the customer question
           does not exist, the Technician will note this deficiency in the
           Seller call tracking system.
      1.5. The Seller Technician will create a call summary for every
           call handled.  This call summary will be recorded in the Seller call
           tracking system.
      1.6. In the event that the customer must be escalated for either
           technical or customer satisfaction reasons, the Technician will do
           so as documented in Customer Satisfaction Escalations section of
           Addendum B.
      1.7. The Seller will assist customers with software installation
           questions for all non-Microsoft software products which are bundled
           with the HP Personal Computer.  The Seller will provide full
           software support (including installation and usage assistance) for
           any Microsoft software product which is bundled with the HP Personal
           Computer.
      1.8. Based on history, some Customers who do not own an HP
           Multimedia computer will call 800 724-6631.  The Seller will
           redirect these customers to the appropriate HP location.  A phone
           list of other HP locations will be provided to the Seller by HP.

2.   DELIVERY AND HANDLING OF END USER HARDWARE FAILURE CALLS
      2.1. In the event that a customer calls for technical assistance
           and the customer is identified as having  some sort of hardware
           failure, the Technician will take one of two action paths:
                  a.  If the customer's product failure is related to a user
                  replaceable part, as defined by HP (such as speakers,
                  microphone, combo card, keyboard, or mouse) the Seller will
                  process the order through the Seller's current relationship
                  and processes that are in place with HP SMO.
                  b.  If the customer's product failure is related to a
                  non-user replaceable part or sub-assembly, the Seller will
                  initiate an on-site repair Customer Support Order (CSO)
                  through the HP SupportLine system.
                  c.  Due to the expensive nature of warranty repairs, the
                  Seller will work to constantly improve the fault isolation
                  process thus minimizing No Parts Used (NPU) for on site
                  repairs and No Trouble Found (NTF) for on-site and
                  replacement parts service.  As HP gather additional
                  information regarding the products covered in this Agreement,
                  specific NPU and NFT measurements will be defined.
      2.2. The Technician will record all call related data in the
           Seller call tracking system.

3.   DELIVERY AND HANDLING OF RESELLER OR HP SALES REPRESENTATIVE CALLS
     3.1.  Authorized HP Resellers and HP Sales Representatives who are
           calling for support on any HP CPO product will call 800-544-9976.
           HP CSC in Boise will validate whether the caller is authorized to
           use the 800-544-9976 phone number.  If the caller is validated by
           HP, calls on the products supported by the seller will be
           transferred from Boise to the Seller.  The Seller is expected to
           provide the same level of technical assistance to Authorized
           Resellers and HP Sales Representatives as for End Users.

                           Addendum B - Page 1 of 7

<PAGE>   12




      3.2. If the Reseller or HP Sales Representative is asking for
           assistance regarding a sales promotion or marketing program, the
           Seller Technician should transfer the call to the Reseller Support
           Group at the CSC in Boise.  HP will communicate to the Seller the
           appropriate transfer phone number for these calls.
      3.3. If the Reseller or HP Sales Representative is asking for
           service assistance (assistance while repairing an HP product), the
           Seller Technician will transfer the caller to the HP Response Center
           in Atlanta (800 430-1801).

4.   CUSTOMER SATISFACTION ESCALATIONS
      4.1. In some cases, Customer satisfaction issues may arise that
           are outside the control of the Seller.  These calls will be
           initially handled by the Seller supervisor or lead.  If no
           resolution which is satisfactory to the Customer can be reached,
           the Customer name, phone number, address, Seller contact and problem
           description will be recorded and sent either electronically or by
           fax immediately to the HP Customer Support Center escalation
           department at (208) 396-4492.  A record of this action will be
           recorded in the Seller's call tracking system.  The call will remain
           in a open status upon escalation.
            4.1.1. Examples of customer satisfactions include:

<PAGE>   13



            Seller will be expected to adjust performance to match HP's
            expectations within a reasonable time period.  The appropriate time
            period for adjustment will be jointly agreed to between HP and the
            Seller.
      7.2. 95% of all calls must be picked up and serviced by a

           on a daily basis.
            7.2.1. Calls will not be pulled from the queue for later call back
                 in order to meet service level objective.
            7.2.2. HP will provide a 3 month rolling forecast to the Seller.
                 This will be provided monthly.  This forecast will include a

                 Seller.
      7.3. No call blockage is acceptable.  Call blockage means: there
           are not enough phone lines to handle the call demand and the
           Customer receives a busy signal.
      7.4. Call resolution rate (the number of customer contacts
           required to reach resolution on a single problem), as identified by

           than 90% success rate for calls handled by the Seller.
            7.6.1. Success rate will be determined by the ratio of positive
                 responses to total responses as scored by CSC call monitoring
                 teams.
            7.6.2. The components of this score will include a combination of
                 communication skills, trouble shooting skills, and technical
                 accuracy.  A copy of the "3rd Party Seller Monitoring Form" is
                 attached as Addendum G.  HP may periodically change the items
                 on the "3rd Party Seller Monitoring Form" in order to better
                 reflect Customer expectations of support delivery.
      7.7. Results of HP CSC silent call monitoring will show 100%

                TechTeam is providing technicians at cost during the training 
                period and does not recover development or delivery expenses

      C.4  MONTHLY PER-TECHNICIAN RUNNING COST

      HP will pay a flat per technician fee for the period April 1, 1995
      through July 31, 1995.  HP must approve the hiring of additional
      technicians for the period April 1, 1995 through July 31, 1995.
      Beginning August 1, 1995, the running cost for this activity will paid
      for by HP via a per talk minute fee.  This per minute fee is yet to be
      determined, but will be something less that $.80 per minute.

      For the period April 1, 1995 through July 31, 1995, the per technical fee
      will be:  $4837.

      The calculation for this fee is:  $.7615 per minute x 76230 minutes per
      year / 12 months = $4837.

      $.7615 per minute is calculated as follows:

           Technician cost per minute              .6923
           Team lead cost per minute               .0428

      C.5  CALL TRACKING DATABASE DEVELOPMENT

      As of March 27, 1995, approximately 600 hours of development
           time has been estimated by National TechTeam as being required for
           initial implementation of a call tracking system for this project.
           These services will be billed at a rate of $65 / hour.  Upon receipt
           of a finalized call tracking system specification from HP, National
           TechTeam will provide to HP a project schedule and the associated
           costs, which will be mutually agreed to by both parties in writing.
           Ongoing enhancements identified by HP will be billed at $65 / hour.
           Additional license fees as required for exclusive use by the HP
           project team (as required and agreed to by mutual written consent of
           both parties) will be billed to HP at National TechTeam's actual
           cost.

                        HP STANDARDS OF BUSINESS CONDUCT

All National TechTeam employees who are involved in the delivery of HP work
will be held to the same Standards of Business Conduct as employees of
Hewlett-Packard Company.  This addendum describes these Standards of Business
Conduct.  All National TechTeam employees who are involved in the delivery of
HP work must read and understand the entirety of this addendum. Any questions
related to any item should be directed through National Tech Team management to
Hewlett-Packard.

Non-compliance with any item described in this addendum will be considered
misconduct by the National TechTeam employee, and will constitute grounds for
immediate removal from all HP activity carried out by National TechTeam.

For purposes adherance to the HP Standards of Business Conduct only, National
Tech Team employees who are involved with HP work must comply with the same
rules as HP employees.  This addendum does not in any way suggest that National
Tech Team employees are directly employed by HP.  National Tech Team should

PRESIDENT'S MESSAGE

Our company's reputation means a lot to us.  It's an asset money can't buy.  It
opens doors for us when we call on customers, when we look for business
partnerships, when we deal with governments, and when we work to improve the
communities in which we operate.  By all measures, HP enjoys one of the best
reputations any company has -- in any business -- anywhere in the world.

This hasn't happened by accident.  Over the years employees at every level have
endeavored to build HP's reputation by fair and honest dealing in every
business transaction and relationship.  Maintaining this reputation is a
critical objective for all entity managers.  We expect every employee to make
this a personal responsibility as well.

These Standards of Business Conduct are intended to inform all employees of
their legal and ethical obligations to HP, its customers, competitors and
suppliers.  Simply stated, every HP employee must comply with these standards.
I expect all managers to review these standards with their employees every year
in order to answer questions and to ensure compliance.  Failure to comply with
these standards is regarded as misconduct and may result in termination of
employment.

Sometimes you may believe an HP employee has engaged in unethical or illegal
conduct.  In this situation, you are expected to notify a manager or the
Personnel Department.  As an alternative, a post
office box has been established by HP's Corporate Legal Department for
worldwide use to receive information on a confidential basis. The address is:
      Hewlett-Packard Company
      Corporate Legal Department (20 BQ)
      Post Office Box 50161
      Palo Alto, CA  94303-0890

The day-to-day performance of each of us adds to -- or subtracts from -- HP's
reputation as a company.  Uncompromising integrity is part of the HP Way and
part of every HP job; it always has been, it always will be.

Lew Platt
President and
Chief Executive Officer

CONFLICTS OF INTEREST
      GENERAL POLICY
            Although you are generally free to engage in personal financial and
            business transactions, this freedom is not unlimited.  You must
            avoid situations where your loyalties may be divided between HP's
            interests and your own interests.  HP wants you to conduct yourself
            so that you do not even appear to have a conflict.   You can avoid
            most unacceptable conflicts by following the rules described below.

      OUTSIDE EMPLOYMENT
            What are the limits on my working for another company or having my
            own business?  HP policy does not prohibit all outside employment,
            but does forbid any outside employment that could lead to divided
            loyalties.  The following examples illustrate some of the
            limitations on outside work:

            *You may not be an employee, consultant or contractor for  any
            competitor of any HP division or operation.  Example:  you may not
            work for a company which makes computers or peripheral products,
            even if your division makes unrelated products.

            *You may not be an employee, consultant or contractor for any HP
            customer or supplier without written approval from your entity
            manager.  Further, you may not have more than one HP employment
            status at a time.  Example:  you may not be an employee at one
            division and also a consultant to another HP entity.

            *You may not sell services or products similar to HP's services or
            products.  Example:  you may not service HP products on your own
            time.

            *You may not engage in activities which support or promote a
            competitor's products or services.  Example:  you may not write and
            sell software for a competitor's products.

            *You may not accept a position with another company if the time
            demands of the position interfere with your HP job.  Example:  a
            position which required receiving phone calls during your HP work
            hours would not be acceptable.

      PERSONAL BENEFIT FROM HP BUSINESS
            When would it be wrong for me to benefit personally from conducting
            HP business?

            You must disclose all situations where you may be conducting HP
            business with friends or family members.  You must obtain written
            approval from your entity manager before conducting business with
            these individuals and you must remove yourself from any involvement
            in the decision to retain their services.  Thus, you would need
            approval to hire your brother-in-law to do repair work on an HP
            facility.  If the entity manager approves, the transaction should
            be handled by your manager or another department, and proposals
            from competing businesses should be considered.

            You may not personally benefit (other than your compensation from
            HP) from any transaction undertaken on behalf of HP.  For example,
            a sales representative may not accept anything of value from an HP
            reseller in return for promoting that company's products.

            You may participate in published frequent traveler programs, except
            those offering cash refunds.  However,  you may not participate in
            frequent purchaser programs outside the travel industry.  As an
            example, you may not accept equipment from an office supply vendor
            based on HP's purchases.

      GRATUITIES FROM THIRD PARTIES





                           Addendum E - Page 2 of 5





<PAGE>   24



            Companies often exchange gifts.  What can I accept?


            Other than inexpensive advertising novelties or business meals and
            entertainment, you and your immediate family may not accept any
            gift, payment, loan, or other favor from a customer, supplier or
            competitor.

            Care should be exercised in accepting business meals and
            entertainment.  Such activities should be infrequent, consistent
            with accepted business practices, and for the express purpose of
            furthering a business relationship.  You should not accept payment
            of travel expenses by a customer or supplier without prior entity
            manager approval.  Some HP organizations may adopt more restrictive
            rules in these matters.

            In rare circumstances, local custom may call for an exchange of
            gifts having more than nominal value as part of a business
            relationship with a foreign company.  In these situations you may
            only accept such gifts on behalf of HP and with the approval of
            your entity manager.  Such gifts should be turned over to HP for
            appropriate disposition such as HP internal use, general employee
            benefit or donation to charity.

      OUTSIDE DIRECTORSHIPS
            What if I am asked to be a director for another organization?

            You may not accept a position as a director of any HP competitor.
            You may not accept a position as director of a company which
            supports or promotes a competitor's products or services, without
            prior approval of the Management Staff.  Before becoming a director
            of any HP customer or supplier, you must obtain the prior approval
            of HP's president or an HP executive vice president.   If you
            encounter any situation as a director which conflicts with HP's
            interests, you will need either to withdraw from participation in
            the decision or resign as a director.

            You may not receive separate compensation (including stock options)
            for service on the board of directors of a company if the service
            is at HP's request or in connection with an HP investment in, or
            relationship with, that company.

      FINANCIAL INTERESTS IN OTHER BUSINESSES
            What personal investments are not acceptable?

            You may not have a financial interest in any HP customer, supplier
            or competitor that might cause divided loyalty or even the
            appearance of divided loyalty.  Whether there is divided loyalty
            depends upon many factors, including:  (a) your ability to
            influence HP decisions that affect your personal interests;  (b)
            the size of the investment relative to your finances; and (c) the
            nature of the relationship between HP and the other business.

      REPORTING POTENTIAL CONFLICTS
            When should I report an outside activity?

            You do not have to report every outside activity.  However, you
            must promptly disclose in writing to your entity manager any actual
            or potential conflicts of interest.  The manager will review the
            matter and communicate HP's position in writing.

            The manager will indicate either (a) that HP has no present
            objection to the relationship, subject to future review, or (b) the
            steps you must take to resolve the conflict to HP's satisfaction.
            Copies of the response and your disclosure will be kept in your
            personnel file.

            When reviewing a potential conflict, HP will consider the following
            questions:

                 -  What kind of outside work will you be performing?

                 - Does the outside work involve an HP competitor, customer or
                 supplier?

                 - Are any HP products or services involved in your outside
                 work?

                 - Does any HP entity offer similar products or services as the
                 entity engaging you for the outside work?

                 - Does the outside work support or promote a competitor's
                 products?

                 - What are your HP duties?

                 - Can you influence HP decisions that affect the outside work?

                 -  Will the outside work impact your ability to perform your
                 HP duties?

                 -  Is this outside work an opportunity HP should take for
                 itself?

                 -  Will you be getting an improper personal advantage?

                 -  Are members of your family, friends, or other HP employees
                 involved in the outside work?

                 -  Are you receiving gratuities, gifts or money that may be
                 improper?

                 -  How will your actions appear to others--both inside and
                 outside HP?


HANDLING COMPANY INFORMATION
      GENERAL POLICY
            HP business information is company property which may not be
            disclosed outside HP unless properly released to the public by HP.
            If you disclose information about existing, new, or proposed
            products or processes, it can hurt HP's competitive position and
            jeopardize R&D efforts.

            You must be sure that confidential or proprietary information is
            appropriately safeguarded against external disclosure as well as
            unauthorized disclosure within HP.  Remember, when you store
            sensitive HP data on a personal computer or workstation, you are
            also responsible for applying the appropriate level of protection.
            Under no circumstances should you disclose it to third parties
            without prior approval from the responsible department manager.
            Where business needs require such information to be disclosed
            outside HP, you must complete appropriate confidential disclosure
            agreements before disclosure.  You should be equally careful when
            releasing prototypes or models.

      CONFIDENTIAL INFORMATION GUIDELINES
            How do I know how sensitive certain information is?

            HP has established guidelines for marking and handling sensitive
            information.  These guidelines establish four classes of sensitive
            information.  No other legends or designations should be used
            within HP.  For a more detailed discussion of how to handle
            confidential and proprietary HP information, you should consult the
            agreement signed by employees at the time of hiring and the HP
            brochure called "Protecting HP Trade Secrets".

            *  "HP Private - Not To Be Copied" - This designation  is used
            for information generated solely for management use to make major
            decisions and must not be disclosed outside HP.  "HP Private"
            documents may be numbered for greater control and must not be
            reproduced without written
            permission of the originator.  Examples include non-public
            consolidated financial information, strategic business plans,
            significant technical product data, R&D proposals and certain
            product marketing strategies.  "HP Private" documents must be
            disposed of by shredding.

            *  "HP Confidential" - This designation is used for
            information which if disclosed would damage HP's interests, such as
            non-public organization charts, and other kinds of personnel
            information, bids, sales forecasts, lab notebooks and customer
            lists.  "HP Confidential" documents should be disposed of by
            shredding.

            *  "For HP Internal Use Only" - This designation  is used for
            information that will have broad distribution, but which is
            considered sensitive and should not go outside HP, such as the
            International Telephone and Communications Directory.  In addition,
            an appropriate designation such as "HP and HP Channel Partner
            Internal Use Only" may be used for documents such as product
            training materials which the business unit specifically decides may
            be shared with HP resellers or other third party channels.

            *  "HP Proprietary" - This designation is used for drawings or
            other documents containing proprietary information made available
            to HP suppliers or other third parties.  These drawings should not
            be duplicated or disclosed except as authorized by the responsible
            HP person.


HANDLING COMPANY ASSETS
      GENERAL POLICY
            Each employee must take care to safeguard HP's assets.   This
            includes protecting them from unauthorized use.  Use of HP assets
            for any unlawful or improper purpose is strictly prohibited.


COMMENTING ABOUT COMPETITORS
      GENERAL POLICY
            Competition is a fact of business life.  HP emphasizes the quality
            of its products and avoids disparaging comments about competitors
            or their products. When you talk about a competitor or its
            products, the statements must be fair, factual and complete.


BUSINESS PRACTICES INVOLVING BOTH END USER AND RESELLERS
      GENERAL POLICY
            You must deal fairly and honestly with HP's customers.  You should
            exercise caution when offering discounts on purchases of different
            product combinations.  Exchange of confidential information is not
            permitted without a written agreement.


CLOSING COMMENT
The practices in this brochure are only some of the legal and ethical standards
you must observe as an HP employee.  Each employee has an important
responsibility to help maintain HP's reputation for the highest standards of
integrity.  If you have any questions, contact your supervisor who will in turn
contact the HP liaison..
