MANCHESTER EQUIPMENT COMPANY
50 MARCUS BLVD
HAUPPAUGE NY 11788
Customer ICN:  1963

Dear MANCHESTER EQUIPMENT COMPANY,

In HP's quest to simplify the contracting and negotiating process, your 1996 HP
Agreement and Addendum is based substantially on your 1995 Agreement and
Addendum. 

In fact, the text of the 1995 Agreement, Addendum and Exhibit L as negotiated
between HP and you is carried forward and repeated in 1996, except for those
modifications indicated in this letter. All other terms and conditions of your
1995 Agreement remain unchanged.

Included with this letter are the new companion documents which form a part of
your 1996 Agreement, the Operations Policy Manual, Product Acquisition and
Resale Categories and Product Exhibits.

AMENDMENTS TO YOUR U.S. RESELLER AGREEMENT:

SECTION 2.A.3
Status Change: Modify to read as follows:

"Undergo a merger, acquisition, consolidation or other reorganization with the
result that any entity controls 50% or more of Reseller's capital stock or
assets after such transaction: or"

SECTION 10
Price Adjustments; Price Protection: Deleted and moved to the Operations Policy
Manual (OPM) as modified.

SECTION 16
Reseller Record Keeping: Modify to read as follows:

"HP or HP's designated will be given prompt access DURING NORMAL BUSINESS
HOURS, either on sight or through other means specified by HP to Reseller's
customer records of account SPECIFICALLY RELATED TO HP PRODUCTS as HP believes
are reasonably necessary to verify and audit Reseller's compliance with this
Agreement" 

AMENDMENT TO YOUR U.S. DEALER ADDENDUM:

SECTION 3.E
Dealer Responsibilities: Deleted and moved as modified to the HP Product
Acquisition and Resale Categories.

   2
SECTION 5
Volume Commitment Levels: Modify to read as follows:

DEALERS AT LEVEL I DISCOUNT

A. Dealer volume commitment levels are described on the attached Product
   Exhibits and are based upon 12 month purchase volume levels.

DEALERS AT LEVEL II DISCOUNT

B. Dealer volume commitment levels are described on the attach Product Exhibits
   and are based upon 12 month SELL-THROUGH volume levels.

If the term of this Agreement or any new Addendum or Product Exhibit is less
than 12 months, an applicable 12 month volume commitment level will be
calculated for Dealer by projection over a full 12 month term.

SECTION 6
Dealer Order Milestones; Modify to read as follows:

A. Unless otherwise specified in the Product Exhibits, as of 5 months after the
   effective date of this Agreement, HP will review Dealer's progress towards
   its volume commitment.

DEALERS AT LEVEL I DISCOUNT

1. If Dealer's orders in those first 5 months represent less than 35% of its 12
   month volume commitment level, HP may terminate all or any part of this
   Agreement.

2. If Dealer's SELL-THROUGH in the first 5 months is 42% or more of the 12 month
   volume commitment level required for greater Dealer discounts, then Dealer
   orders during the remaining term of this Agreement will be subject to those
   greater discounts.

3. If Dealer later cancels any order that resulted in HP granting Dealer a
   higher discount level, HP may reduce Dealer's discount to the level which
   would have applied had all orders never been placed.

DEALERS AT LEVEL II DISCOUNT

4. If Dealer's SELL-THROUGH in those first 5 months represent less than 35% of
   its 12 month volume commitment level, then Dealer's orders during the
   remaining term of this Agreement will be subject to the lower Dealer
   discounts corresponding to the 12 month volume commitment level projected by
   Dealer's orders in those first 5 months. If the projected orders are below
   HP's minimum volume commitment level, HP may terminate all or any part of
   this Agreement.

B. Dealer discounts for orders during the first 5 months of this Agreement will
   not be affected by the milestone adjustments above.

PRODUCT EXHIBIT(S):

U20I/U30I

Effective March 1, 1996 the U20I AND U30I PRODUCT EXHIBITS WILL BE MERGED
TOGETHER INTO THE U20I FULL LINE RESELLER EXHIBIT. The 10M commitment level
will continue to be based on orders. The 135M commitment level will be changed
from order based to SELL-THROUGH based.

                by HP.

        C.      HP must approve proposed Reseller changes prior to any
                obligation of HP to perform under this Agreement with Reseller 
                as changed.

                current List Prices for HP Products ("List Prices"). HP reserves
                the right to change List Prices and discounts upon reasonable
                notice to Reseller. If Reseller is unsure of the List Price to
                use in calculating net Reseller price for any HP Product,
                Reseller should contact its HP sales representative.

        B.      Net Reseller price for HP Products purchased under this
                Agreement will be the List Price at the time of Reseller's
                orders, less the discounts based on Reseller's volume or other
                commitments or elections specified in the Product Exhibits.

        C.      Net Reseller price includes shipment arranged by HP. HP
                reserves the right to charge Reseller for any special routing,
                handling or insurance requested by Reseller and agreed to by HP.
                Orders shipped special routing will be F.O.B. Origin.

        D.      Net Reseller price excludes State and local taxes. HP will
                invoice Reseller for these taxes, based on point of delivery,
                unless the appropriate resale exemption certificates are on file
                at HP's order-entry point or HP agrees the sale is otherwise
                exempt.

        E.      Upon request from Reseller, at its discretion HP may grant
                special pricing for particular end-user customer transactions.
                In good faith, HP may retract the special pricing at any time
                before acceptance by the end-user customer. HP may extend the 
                pricing on an exclusive or non-exclusive basis and may condition
                the pricing on a pass-through of all or part of the non-standard
                offering extended by HP.

8.      PAYMENT AND SECURITY TERMS

        A.      Reseller will pay invoices within 30 days from the date of the
                invoice. HP reserves the right to change credit terms at any
                time when in HP's opinion Reseller's financial condition or
                previous payment record so warrants.

        B.      Any Reseller claim for adjustment of an invoice is agreed to be 
                waived if Reseller fails to present it within 90 days from date
                of HP invoice. No claims, credits or offsets may be deducted
                from any invoice.

        C.      If Reseller fails to pay any sum due within 15 days of HP's
                written notice of delinquency, HP may discontinue performance
                under this Agreement and may revise credit terms for unshipped 
                orders.

        D.      [Deleted]

9.      ORDERS; SHIPMENTS; CANCELLATIONS AND CHANGES

        A.      Reseller's orders must comply with the minimum order, release,
                ship-to and other requirements specified in this Agreement.

        B.      HP will honor written, fax and telephone orders from Reseller's
                approved locations. Reseller is responsible for ensuring that 
                only authorized employees place, change or delete orders and
                that the orders conform to all requirements of this Agreement.

        C.      Reseller's requested date for shipment must be within 90 days
                after order date. HP reserves the right to schedule and
                reschedule any order, at HP's discretion, and to decline any
                order for credit reasons or because the order specifies an 
                unreasonably large quantity or makes an unreasonable shipment
                request.
            
        D.      HP will use reasonable efforts to meet scheduled shipment
                dates. However, HP will not be liable for delay in meeting a
                scheduled shipment date.

        E.      Reseller must own more than 50% of its business at each approved
                location. HP will ship HP Products to Reseller under HP's
                standard shipment terms and conditions but only to approved 
                Shipment Locations authorized by HP on Exhibit L. Shipment 
                Locations may be the same as company-owned Selling Locations.
                All Reseller's sales, advertising and promotional activities for
                HP Products must be conducted from Selling Locations approved by
                HP. No sales, advertisement or promotion of HP Products may be 
                conducted from Shipment   
                               
         
   8
        Locations which are not also approved company-owned Selling Locations.

        However, HP will ship to a maximum of six approved Shipment Locations
        and will accept orders only from a single order point. An exception will
        be made where a Product Exhibit indicates drop shipment is available for
        a specific HP Product under a special program; drop shipment for those
        HP Products will be subject to limitations indicated in the Product
        Exhibits.

    F.  Shipments are subject to availability. If HP Products are in short
        supply, HP will allocate them equitably, at HP's discretion.

    G.  Title to HP Products and risk of loss and damage will pass to Reseller
        F.O.B. Destination.

10. PRICE ADJUSTMENTS; PRICE PROTECTION

    A.  If HP raises Net Reseller prices (either through List Price increases or
        Product Exhibit discount reductions) HP will invoice Reseller based on
        the old List Price or discount for affected HP Product orders placed by
        Reseller within one month after the effective date of the increase.
        Limited quantity restrictions may apply.

    B.  If HP reduces Net Reseller prices (either through a List Price reduction
        or a combination of List Price and discount changes), HP will invoice
        Reseller based on the reduced Net Reseller price for affected HP
        Products shipped on or after the effective date of the reduction.

    C.  If HP offers a limited time promotional HP Product discount to all
        Resellers (excluding rebates and spiffs of all forms), HP will invoice
        Reseller based on the Net Reseller price less the promotional discount
        for orders conforming to and shipments made pursuant to the terms and
        conditions of the promotion.

    D.  If HP reduces Net Reseller prices or offers a limited time HP Product
        promotional discount to all Resellers and the HP Products are eligible
        for price protection as designated on the Product Exhibits, then HP will
        grant Reseller a price protection credit calculated by one of the two
        following methods at HP's discretion;

        1.  The credit will equal the total reduction in Net Reseller price
            (less any previous promotional discount available from HP) for those
            HP Products in Reseller's inventory and in transit to Reseller on
            the effective date of the reduction, using a verification process
            determined by HP; or

        2. The credit will equal 100% of the total reduction in Net Reseller
            price (less any previous promotional discount available from HP) for
            those HP Products shipped within 30 days before the effective date
            of the reduction, or 75% of the reduction for those HP Products
            shipped within 60 days before that date, whichever is greater.

    E.  To receive a price protection credit by the inventory method, Reseller
        upon notification of a change in price from HP and upon request, will
        complete, sign and return to HP a form showing the number of units
        (including serial numbers) in inventory and in transit to Reseller on
        the effective date of the reduction. The format for the form may be
        defined by Reseller but must meet the approval of HP. If Reseller fails
        to submit the form within 30 days of the effective date of the
        reduction, Reseller will receive no price protection for eligible
        products.

    F.  In all cases, HP may require that Reseller accumulate a minimum credit
        of $200 within a particular month before HP extends price protection to
        Reseller for that month.

    G.  HP reserves the right to offer Reseller obsolete, used or refurbished HP
        Products and to offer Reseller HP Products through special promotions at
        discounts different from those in the Product Exhibits and on terms
        which may not include rights to price protection, stock adjustment,
        promotional funds allowance or count towards Reseller's volume
        commitment levels.

11.  SOFTWARE

    Reseller is granted the right to distribute software materials supplied by
    HP only in accordance with the license terms supplied with these materials.
    Reseller may alternatively acquire the software materials from HP for its
    own demonstration purposes in accordance with the terms for use in those
    license terms.

12.  TRADEMARKS

    A.  From time to time, HP may authorize Reseller to display one or more
        designated HP trademarks. Reseller may display the trademarks solely to
        promote HP Products. Any display of the trademarks must be in good
        taste, in a manner that preserves their value as HP trademarks, and in
        accordance with standards provided by HP for their display. Reseller
        will not use any name or symbol in a way which may imply that Reseller
        is an agency or branch of HP; Reseller will discontinue any such use of
        a name or mark as requested by HP, Any rights or purported rights in any
        HP trademarks acquired through Reseller's use belong solely to HP.


    B.  Reseller grants HP the non-exclusive, royalty free right to display
        Reseller's trademarks in advertising and promotional material solely for
        directing prospective purchasers of HP Products to Reseller's Selling
        Locations. Any display of the trademarks must be in good taste, in a
        manner that preserves their value as Reseller's trademarks, and in
        accordance with standards provided by Reseller for their display. Any
        rights or purported rights in any Reseller trademarks acquired through
        HP's use belong solely to Reseller.

13.  WARRANTY

    A.  HP Product User Warranties are described on the Product Exhibits and
        apply only to end-user purchasers of HP Products. HP revisions to the
        User Warranties will be effective on the date specified by HP. Copies of
        User Warranties will be supplied with HP Products. Reseller must provide
        a copy of the associated User Warranty for an HP Product to each
        end-user prior to sale.
    
    B.  HP Product Warranty begins upon purchase by the end-user customer and
        shall be verified by proof of acquisition by the end-user or via HP's
        electronic warranty verification system.



    C.  HP PRODUCT USER WARRANTIES ARE THE EXCLUSIVE WARRANTIES COVERING HP
        PRODUCTS AND ARE IN LIEU OF ANY OTHER WARRANTIES, WRITTEN OR ORAL,
        EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES
        OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

    D.  Some HP Products may contain selected remanufactured parts equivalent to
        new in performance.

14.  LIMITATION OF REMEDIES AND LIABILITY

    A.  The remedies provided in this Agreement are Reseller's sole and
        exclusive remedies against HP.

    B.  HP will be liable for damage to tangible property, bodily injury or
        death to the extent a court of competent jurisdiction determines that an
        HP Products sold under this Agreement is defective and has directly
        caused such damage, injury or death, provided that HP's liability for
        damage to tangible property will be limited to $300,000 per incident.
   9
        C.  HP will be liable to Reseller for any net credits due from HP
            pursuant to the express provisions of this Agreement. In no
            event will HP be liable for loss of data, for indirect, special,
            incidental or consequential damages (including lost profits) or
            for any other damages whether based on contract, tort, or other
            legal theory.

15.  INTELLECTUAL PROPERTY INDEMNITY

        A.  HP will defend any claim against Reseller that any HP Product
            infringes a patent, utility model, industrial design, copyright,
            mask work or trademark in the country where Reseller acquires or 
            sells the Product from HP, provided that Reseller:

            1.  Promptly notifies HP in writing of the claim; and

            2.  Cooperates with HP in and grants HP sole authority to control
                the defense and any related settlement.

            HP will pay the cost of such defense or settlement and any costs
            and damages finally awarded by a court against Reseller.

        B.  HP's indemnity shall extend to Reseller's customers and end-users
            under this Agreement provided they comply with the obligations
            above.
 
        C.  HP may procure for Reseller, its customers and end-users the  
            right to continued sale or use, as appropriate, of the Product or
            HP may modify or replace the Product. If a court enjoins the sale
            or use of the Product and HP determines that none of the above
            alternatives is reasonably available, HP will accept return of the
            Product and refund its depreciated value.

        D.  HP has no obligation for any claim of infringement arising from:

            1.  HP's compliance with any designs, specifications or instructions
                of Reseller;

            2.  Modification of the Product by Reseller or a third party;

            3.  Use of the Product in a way not specified by HP; or

            4.  Use of the Product with products not supplied by HP.

        E.  This Section states HP's entire liability to Reseller and its
            customers and end-users for infringement.

16.  RESELLER RECORD-KEEPING

        A.  For contract compliance verification, product safety information,
            operational problem correction and the like, Reseller must
            maintain records of customer purchases of printers, plotters, taxes,
            scanners and computers for one year. Records must include
            customer name, address, phone number, ship-to address, serial
            number and date of sale of the above products.

        B.  HP may require Reseller to provide HP or HP's designate with HP
            Product inventory and sales data including, but not limited to,
            information such as total units of selected HP Products sold and
            held in inventory by month for each approved location, in a format
            specified by HP. HP may require monthly reporting incorporating
            the previous month's data for each approved location.

        C.  In addition, Reseller must comply with any reporting requirements
            for HP programs.

        D.  At HP's discretion and upon notice to Reseller, HP or HP's 
            designate will be given prompt access, either on site or through
            other means specified by HP, to Reseller's customer records,
            inventory records and other books and records of account as HP
            believes are reasonably necessary to verify and audit Reseller's 
            compliance with this Agreement.

        E.  Failure to promptly comply with HP's request will be considered a
            repudiation of this Agreement justifying HP's termination of
            this Agreement on 30 days' notice--without further cause.

        F.  HP may recover all reasonable actual costs associated with
            compliance verification procedures from any promotional funds,

        A.  From time to time, HP may add products to or delete them from the
            Product Exhibits, or implement or change HP policies or programs
            at HP's discretion, after reasonable notice to Reseller.

            Additionally, HP may give Reseller written notice of any other
            amendment to this Agreement upon at least 30 days' advance notice.

            on the effective date specified in the notice.

        C.  Each party agrees that the other has made no commitments regarding
            the duration or renewal of this Agreement beyond those expressly
            stated in this Agreement.

18.  TERMINATION OF AGREEMENT

        A.  Either party may terminate this Agreement without cause at any
            time upon 30 days' written notice or with cause at any time upon
            15 days' written notice to the other party.

        B.  If either party gives the other notice of termination or advises
            the other of its intent not to renew this Agreement, HP may require
            that Reseller pay cash in advance for additional shipments during 
            the remaining term, regardless of Reseller's previous credit
            status, and may withhold all such shipments until Reseller pays
            its outstanding balance.

        C.  Upon termination or expiration of this Agreement for any reason,
            Reseller will immediately cease to be an authorized HP Reseller
            and will refrain from representing itself as such and from using
            any HP trademark or trade name.

        D.  Upon any termination or expiration, either party may require that
            HP purchase from Reseller any HP Products purchased under this
            Agreement that are on HP's then current Product Exhibits, which
            are in their unopened, original packaging and marketable as
            new merchandise. The repurchase price shall be the lower of either
            the Net Reseller Price on the date of termination or expiration or
            Reseller's original purchase price, in each case less any
            promotional or other discounts or price protection or other
            credit extended by HP to Reseller for the HP Product. Reseller
            should contact its HP sales representative for information about
            the items eligible for repurchase and instructions for their
            return at HP's expense.

        E.  Upon termination of this Agreement or expiration without renewal
            all rights to any accrued Advantage Program or other promotional
            funds will automatically lapse.

        F.  The indemnities provided in this Agreement will survive termination
            or expiration of this Agreement.

19.  RELATIONSHIP

        A.  Reseller's relationship with HP will be that of an independent
            contractor. Nothing stated in this Agreement shall be construed as
            making Reseller and HP a franchise, joint venture or
            partnership.




   10
    B.  Unless expressly authorized by HP in writing in advance, any commitment
        made by Reseller to its customers with respect to price, quantities,
        delivery, specifications, warranties, modifications, interfacing
        capability or suitability will be Reseller's sole responsibility, and
        Reseller will indemnify HP from liability for any such commitment by
        Reseller.

    C.  List Prices are suggested prices for resale to end-user customers and a
        basis for calculating Net Reseller price. Reseller has the right to
        determine its own resale prices, and no HP representative will require
        that any particular resale price be charged by Reseller or grant or
        withhold any treatment to Reseller based on Reseller's resale pricing
        policies. Reseller agrees that it will promptly report any effort by
        HP personnel to interfere with its pricing policies directly to an HP
        officer or manager.

    D.  This Agreement applies only to the HP Products listed on the Product
        Exhibits (U.S. versions only). Reseller acknowledges that HP may
        market other products, including products in competition with those 
        listed on the Product Exhibits without making them available to
        Reseller. HP reserves the right to advertise, promote and sell any
        product, including HP Products on the Product Exhibits, in competition
        with Reseller.

    but not limited to the Advantage Program, Premier Support program and other
    programs and policies in HP's Operations Policy Manual, participation in
    which will be on the current terms and conditions of the policies &
    programs.

21. GENERAL CONDITIONS

    A.  Neither party may assign any rights or obligations in this Agreement
        without the prior written consent of the other party. Any attempted
        assignment will be deemed void.

    B.  Neither party's failure to enforce any provision of this Agreement
        will be deemed a waiver of that provision or of the right to enforce
        it in the future.

    C.  This Agreement, including the attached Addenda, associated Product
        Exhibits and Product Categories contains the entire understanding
        between the parties relating to its subject matter. HP hereby gives
        notice of objection to any additional or inconsistent terms set forth
        in any purchase order or other document issued by Reseller. Except as
        provided in paragraphs 17A and 17B of this Agreement, no modification of
        this Agreement will be binding on either party unless made in writing
        and signed by both parties.

        this Agreement or binding on either party unless specifically accepted
        in writing and signed by both parties.

    E.  This Agreement will be governed by the laws of the State of California.

    F.  If any clause of this Agreement is held invalid, the remainder of this
        Agreement will continue unaffected.

                              U.S. DEALER ADDENDUM

1.      APPOINTMENT

        A.      HP appoints the Reseller as a Dealer.

3.      DEALER RESPONSIBILITIES

        A.      Dealer will advertise, promote and sell HP Products only
                through the company name(s) and approved Selling Locations
                listed on Exhibit L and only to end-user customers (including
                government and corporate users as well as individual users)
                or to resellers as permitted in the Product Categories.

        B.      Dealer agrees to:

                1.      Advertise, promote, demonstrate and sell HP Products on
                        a face-to-face basis and provide pre-sales support and
                        post-sales technical support to all Customers.

                2.      Maintain at each approved Selling Location a facility in
                        which HP Products are displayed or demonstrated on a
                        regular basis to end-user customers.

                3.      Use catalogs and telemarketing sales techniques only in
                        conformity with current HP policies and only as a
                        complement to face-to-face sales activity unless
                        nationwide advertising for the HP Product is permitted
                        in the Product Categories.

                4.      Ensure that no sale, advertising, promotion, display or
                        disclosure of any features, availability or price of any
                        new HP Product takes place before HP's public 
                        announcement of that Product.

                5.      Identify and keep current a primary and secondary
                        support contact for both marketing communications and
                        post-sales technical support at each approved Selling
                        Location.

                6.      Report promptly to HP all suspected defects in HP 
                        Products.

                7.      Assist its customers in obtaining warranty repairs for
                        HP Products by either repairing the product itself,
                        referring the customer to HP or an approved HP repair
                        provider, or returning the HP Product to HP. If Dealer
                        elects to provide warranty repair services to its
                        customers, Dealer will comply with the terms and
                        conditions outlined in the HP Premier Support Program 
                        Guide.

                8.      Ensure that its employees complete any required training
                        courses and certification programs designated by HP.

        C.      Without HP's prior written consent, Dealer will not export HP
                Products to any customer outside the U.S., nor will Dealer sell
                HP Products for export outside the U.S.

        D.      Except for sales to resellers permitted in the Product 
                Categories, Dealer may not sell HP Products to or buy them from
                other resellers for stock balancing or any other reason.

        E.      Dealer may not sell, rent or lease HP Products to rental
                companies or leasing companies for their subsequent rental or
                lease.

5.      VOLUME COMMITMENT LEVELS

        A.      Dealer volume commitment levels are described on the attached
                Product Exhibits and are based upon 12 month purchase volume
                levels.

        B.      If the term of this Agreement or any new Addendum or Product
                Exhibit is less than 12 months, an applicable 12 month volume
                commitment level will be calculated for Dealer by projection
                over a full 12 month term.

6.      DEALER ORDER MILESTONES

        A.      Unless otherwise specified in the Product Exhibits, as of 5
                months after the effective date of this Agreement, HP will
                review Dealer's progress towards its volume commitment.

                1.      If Dealer's orders in the first 5 months are less than
                        35% of its 12 month volume commitment level, then
                        Dealer's orders during the remaining term of this
                        Agreement will be subject to the lower Dealer discounts
                        corresponding to the 12 month volume commitment level
                        projected by Dealer's orders in the first 5 months. If
                        the projected orders are below HP's minimum volume
                        commitment level, HP may terminate all or any part of
                        this Agreement.

                2.      If Dealer's orders in the first 5 months are 42% or
                        more of the 12 month volume commitment level required
                        for greater Dealer discounts, then Dealer's orders
                        during the remaining term of this Agreement will be
                        subject to those greater discounts.

                3.      Dealer discounts for orders during the first 5 months
                        of this Agreement will not be affected by the milestone
                        adjustments above.

        B.      If Dealer later cancels any order that resulted in HP granting
                Dealer a higher discount level, HP may reduce Dealer's discount
                to the level which would have applied had all canceled orders
                never been placed.

9.      ORDERS; SHIPMENTS; CANCELLATIONS AND CHANGES

        A.      Minimum resale shipments for 12 months for each approved
                location are $100,000 of HP Products measured by Dealer's
                Net Reseller price from HP.

        B.      Notwithstanding Section 9.E of the U.S. Reseller Agreement,
                Dealer may elect more than six ship to locations. This election
                will result in a 1% reduction in Dealers discount. In either 
                case, the single order point requirement of Section 9.E of the
                U.S. Reseller Agreement remains. Dealer's election can be
                changed only at the time of the 5 month milestone review.

        C.      Regardless of Dealer's shipment election, supplies and
                accessories on Exhibit U40X will be drop shipped to approved
                Shipment Locations without charge to Dealer.

                                                   U.S. DAVAR SALES AMENDMENT
                                        [EFFECTIVE ONLY THROUGH MAY 31, 1995]

1.  Sales to DAVARs must meet the published requirements of HP's DAVAR Program
    including, but not limited to the following:

    A.  HP's DAVAR program expires May 31, 1995. Reseller may sell HP Products
        through May 31, 1995 only to those DAVARs who have an existing DAVAR
        Certification from HP. No new DAVAR applications will be accepted by HP.

    B.  Reseller is responsible for understanding, monitoring, and enforcing the
        DAVAR Program terms and conditions. Unauthorized sales by DAVAR may
        result in termination of both Reseller and the DAVAR.

    C.  Reseller will apply any Advantage Program funds or other promotional
        funds, facilities or services in conformity with HP guidelines and a
        mutually agreed plan between Reseller and DAVAR.

    D.  Reseller agrees that all Record-Keeping provisions of its Agreement
        apply to its sales of HP Products to DAVARs, including the monthly
        reporting of sales and inventory and the recovery of HP audit costs from
        Reseller for audits of DAVARs.

    E.  HP may withdraw its permission for sales to a DAVAR, with or without
        cause at any time, by notifying Reseller in writing.
