                        TERMS AND CONDITIONS OF AGREEMENT


1.   LOCATION. During the Term (as defined in Section 6 (a) below), NAI shall
     provide the following marketing considerations to Co-Host:

     (a)  Co-Hosting Rights. Co-Host shall be permitted to maintain on the
          Online Service Page (as defined in Part 2 of Exhibit "A") of the
          Originating Locations in the manner set forth on Exhibit "B" hereto
          (and on such other positions as are set forth on Exhibit "B" or as the
          parties may mutually agree upon in writing from time to time) a hot
          link to Internet locations specified by the Co-Host (the
          "Destination") from which Goods (other than Competitor's Goods
          (hereinafter defined)) may be sold. The web pages at the Destination
          shall be maintained in accordance with the requirements of this
          Agreement, including without limitation, Section 2 hereof.
          "Competitor's Goods" as used herein shall mean the Goods of any of the
          persons or entities described on Part 1 of Exhibit "C" attached hereto
          and made a part hereof. The Destination shall not contain any links to
          any third party sites for the purchase of Competitor's Goods; provided
          that the Destination will link to the Co-Host Site (which will sell
          Competitor's Goods).

     (b)  Exclusive Positioning. Co-Host shall be the exclusive reseller of
          software products ("Software") at the Originating Locations. The
          preceding sentence shall not prohibit NAI from (i) reselling Software
          including NAI Goods (hereinafter defined) from the McAfee Mall; (ii)
          referencing and linking to sites of strategic partners (other than
          competitors of Co-Host listed on Part 2 of Exhibit "C") which may also
          be involved in the resale of Software from such sites; provided that
          no Software may be purchased on the page of such site which is linked
          to any Originating Location and further provided that the references
          and links to the sites of strategic partners shall not be placed on
          the [*]; and (iii) advertising [*] with banners, buttons and other
          forms of online advertising; provided that any link from such
          advertising takes the end user to [*] and not a reseller of Goods
          (other than Co-Host). For example, an advertising banner or button for
          the [*] may link back to the website of [*] but not the website of [*]
          which is reselling the program. Without limitation on the foregoing,
          NAI may co-host a [*] on the Originating Locations. NAI will obtain a
          written covenant that the [*] co-host will present [*] and upon
          request of Co-Host will require removal or alteration of [*] by such
          co-host on such co-hosted facility which Co-Host reasonably deems to
          be [*]; provided, however, that, notwithstanding the foregoing,
          Co-Host may be [*] on any such service.

     (c)  Short Term Product Exclusives. For a period of [*] of [*] or [*],
          Co-Host shall be the [*] any such


*Confidential treatment requested. Certain confidential information has been
 omitted and filed separately with the Securities and Exchange Commission.

                                       3
<PAGE>   4

          [*] during the Term. "NAI Goods" as used herein shall
          mean retail desktop software products offered by NAI under the
          "McAfee" brand or other NAI owned brand, which NAI makes available for
          resale through distributors and resellers via the Internet.

     (d)  Reference Site. Co-Host may refer to the Originating Locations as a
          Co-Host customer location and to NAI as a Co-Host customer hereunder
          provided all such references shall be subject to the prior review and
          approval of NAI, which approval will not be unreasonably withheld.

     (e)  Links to Online Service Page. Any end user accessing the principal
          URLs of NAI (e.g., mcafee.com, cybermedia.com, pgp.com, tis.com) shall
          be taken to the Online Service Page. Any end user accessing a "buy"
          button on any of the Originating Locations shall be taken to the
          Online Service Page. NAI shall not sell [*] (other than the McAfee
          Mall).

          NAI reserves the right to change the URL of the Originating Locations
          from time to time and agrees to give Co-Host as much notice of any
          such change as is practicable.

2.   MARKETING AND SALES.

     (a)  Placement of Order. In consideration of the Co-Hosting Fee set forth
          in Part 3 of Exhibit "A", NAI shall provide the marketing
          consideration identified in Section 1 during the Term of this
          Agreement.

     (b)  Advertising Materials; Destination Operation. Co-Host shall provide to
          NAI artwork and text materials with respect to the advertisement of
          the Destination at the Originating Locations. Such artwork and
          materials must be non-infringing, inoffensive, accurate, truthful and
          otherwise comply with all applicable laws. Co-Host shall comply with
          all applicable laws in connection with the operation of the
          Destination, including without limitation, requirements regarding the
          confidentiality of information concerning end users. NAI retains the
          right, but not the obligation, to disapprove or remove any
          advertisements or advertising materials it reasonably deems illegal,
          inappropriate or otherwise inconsistent with the purposes of the
          Originating Sites, without the consent of Co-Host.

     (c)  Use of Trademarks. Co-Host hereby grants to NAI a non-exclusive,
          non-transferable, royalty-free license during the term of this
          Agreement to use the trademarks, service marks and trade names of
          Co-Host in connection with the advertising and promotion of the Goods
          from the Originating Locations, provided that NAI complies with the
          terms of Section 9(b) of the Web Site Services Agreement (as defined
          below). Co-Host reserves the right to terminate the foregoing right,
          after giving NAI notice and opportunity to cure the allegedly harmful
          use, if in Co-Host's reasonable judgment, NAI's use of such
          trademarks, service marks and trade names harms the business, image or
          goodwill of Co-Host.


*Confidential treatment requested. Certain confidential information has been
 omitted and filed separately with the Securities and Exchange Commission.

                                       4
<PAGE>   5

     (d)  Limited Duty of Promotion. NAI shall have no duty or obligation to
          advertise or promote the Goods, other than as set forth in this
          Section 2. Except as expressly set forth herein (including, without
          limitation, as set forth in this Section 2(d)), NAI does not,
          expressly or impliedly, guaranty or warrant any results or level of
          sales or customer leads to Co-Host. NAI reserves the right to cease
          publication of the Originating Locations for brief periods from time
          to time for maintenance or other purposes; provided that the
          Originating Locations will comply with the same "Uptime Requirements"
          specified with respect to the "Managed Site" in the Web Site Services
          Agreement.

     (e)  Marketing Promotions. During the Term, Co-Host and NAI will regularly
          discuss and implement mutually agreed upon jointly funded marketing
          promotions. NAI and Co-Host hereby agree that the marketing promotions
          set forth on Exhibit "D" hereto will be implemented as set forth on
          Exhibit "D".

     (f)  Distribution of Physical Products. NAI grants to Co-Host the right to
          distribute physical copies of NAI's Goods to end users ordering from
          the Managed Site, the Destination or Beyond.com upon the terms set
          forth in Exhibit "E" attached hereto and made a part hereof.

3.   PAYMENT AND RECORDS.

     (a)  Fees. Subject to the provisions of Section 6 hereof, Co-Host shall pay
          to NAI the amount designated in Part 3 of Exhibit "A" as the
          Co-Hosting Fee upon the schedule set forth in such Part.

     (b)  Payment Terms. Except as set forth in such Part 3 of Exhibit "A",
          payments from Co-Host to NAI shall be due thirty (30) days from the
          date of invoice. All payments will be made in United States dollars,
          free of any taxes then currently applicable, at the address designated
          above by NAI. Late payments shall bear interest at the lesser of: (i)
          the maximum rate permitted by law, and (ii) the rate of 1.5% per month
          from the due date until paid.

4.   EQUITABLE RELIEF. Each party acknowledges that any breach of its
     obligations under this Agreement with respect to the proprietary rights or
     confidential information of the other party will cause the other party
     irreparable injury for which there are inadequate remedies at law, and
     therefore such other party will be entitled to equitable relief in addition
     to all other remedies provided by this Agreement or available at law.

5.   PROPRIETARY RIGHTS. NAI retains ownership of the NAI Internet Site, the
     Originating Locations, the trademarks and all intellectual property rights
     in connection with the NAI Internet Site, including without limitation, its
     URL designations and all rights from InterNIC in connection therewith.
     Co-Host and its licensors retain ownership of all intellectual property
     rights in the advertising materials provided, the trademarks and all
     intellectual property rights in connection with the Destination and the
     Co-Host Site, including, without limitation, its URL designations and all
     rights from InterNIC in connection therewith, and all of its other
     intellectual property rights.

          other party engages in any material unlawful business practice and
          such practice continues uncured [*] following written notice thereof,

          Exhibit "A").

7.   CONFIDENTIALITY. Confidential Information disclosed by either party in
     writing and marked as "confidential," proprietary" or the like (or
     disclosed verbally if a written summary is provided within thirty days),
     including any information relating to such party's research, development,
     proprietary technology, product and marketing plans, finances, personnel
     and business opportunities will be considered confidential information.
     Each party will not use the other party's confidential information except
     as required to achieve the objectives of this Agreement and will not
     disclose such confidential information except to employees, agents and
     contractors who have a need to know in the discharge of their duties under
     this Agreement. Such restrictions will not apply to information that
     becomes public knowledge other than through the disclosing party, is

     Neither party will make any disclosure of, or statement covering, the terms
     of this Agreement, including the financial terms, to any third parties
     (other than its attorneys, accountants and professional consultants),
     without obtaining the other's prior written consent, except as required by
     court order or applicable regulatory authorities, including without
     limitation, the rules and regulations of the Securities and Exchange
     Commission, any stock exchange and the NASDAQ. The parties agree that under
     their current understanding, disclosure of the financial terms of this
     Agreement is not required under the foregoing rules and regulations. The
     obligations of this Section 7 shall survive the termination of this
     Agreement, under any circumstances. The parties shall make a joint press
     release announcing the relationship, the timing and content of which shall
     be subject to the mutual agreement of the parties.

8.   RELATIONSHIP OF THE PARTIES. The parties are independent contractors and
     not partners, joint venturers or agents, and neither party may obligate the
     other to any warranty or other obligation. Neither NAI nor Co-Host is by
     virtue of this Agreement authorized as an agent or other representative of
     the other party.

9.   REPRESENTATIONS, WARRANTIES AND INDEMNIFICATION.

     (a)  Co-Host represents and warrants to NAI that Co-Host has all right,
          title, ownership interest and/or marketing rights necessary to provide
          the advertising materials to NAI, to perform its obligations hereunder
          and to operate the Destination. Each party further represents and
          warrants to the other that it has not entered into any agreements or
          commitments which are inconsistent with or in conflict with the rights
          granted or obligations incurred by the representing party in this
          Agreement. Co-Host further represents and warrants that the
          advertising materials supplied hereunder do not infringe any Covered
          Country (hereinafter defined) copyright, trademark, or trade secret
          right. Covered Country shall mean the United States of America and any
          member state of the European Economic Union. Co-Host agrees that, if
          notified promptly in writing and given sole control of the defense and
          all related settlement negotiations, it will defend NAI, its
          employees, officers and agents, against any claim based on an
          allegation that (i) advertising materials supplied hereunder infringes
          a Covered Country patent, copyright, trademark or state trade secret
          right, or (ii) Co-Host violated any law, statute or ordinance or any
          governmental or administrative order, rule or regulation with regard
          to the advertising materials, the operation of the Destination or the
          manufacture, possession, distribution, use or sale of the Goods.
          Co-Host will pay any resulting costs, damages and attorneys' fees
          finally awarded by a court, or agreed to in settlement by Co-Host,
          with respect to any such claims. NAI agrees that, if the advertising
          materials become, or in Co-Host's opinion are likely to become, the
          subject of an infringement claim, NAI will permit Co-Host, at
          Co-Host's option and expense, to, among other things, procure the
          right for NAI to continue marketing and using the advertising
          materials, or to replace or modify them so that they become
          non-infringing.



                                       7

     (b)  NAI represents and warrants that NAI has all right, title, ownership
          interest and/or marketing rights necessary to operate the Originating
          Locations, provide the Products to Co-Host, and the Products shall be
          free and clear of all liens and encumbrances. NAI further represents
          and warrants that it has not entered into any agreements or
          commitments which are inconsistent with or in conflict with the rights
          granted to Co-Host in this Agreement. NAI further represents and
          warrants that the Products supplied hereunder do not infringe any
          Covered Country patent, copyright, trademark, or trade secret right.
          NAI agrees that, if notified promptly in writing and given sole
          control of the defense and all related settlement negotiations, it
          will defend Co-Host, its employees, officers and agents against any
          claim based on an allegation that (i) a Product supplied hereunder
          infringes a Covered Country patent, copyright, trademark or trade
          secret right, or (ii) NAI violated any law, statute or ordinance or
          any governmental or administrative order, rule or regulation with
          regard to a Product or its manufacturer, possession, use or sale. NAI
          will pay any resulting costs, damages and attorneys' fees finally
          awarded by a court, or agreed to in settlement by NAI, with respect to
          any such claims to the extent of the compensation received under this
          Agreement. Co-Host agrees that, if the Products in the inventory of
          Co-Host, or the operation thereof, become, or in NAI's opinion are
          likely to become, the subject of an infringement claim, Co-Host will
          permit NAI, at NAI's option and expense, to, among other things,
          procure the right for Co-Host to continue marketing and using such
          Products, or to replace or modify them so that they become
          non-infringing. If neither of the foregoing alternatives is available
          on terms that NAI deems reasonable, Co-Host will return such Products
          on written request from NAI. NAI will grant Co-Host a credit equal to
          the price paid by Co-Host for such returned Products, as adjusted for
          discounts, returns and credits actually given, provided that such
          returned Products are in an undamaged condition. NAI will have no
          obligation to Co-Host with respect to infringement of patents,
          copyrights, trademarks or trade secrets or other proprietary rights
          beyond that stated in this Section 9(b).

     (c)  No Combination Claims. Notwithstanding Section 9(b), NAI will not be
          liable to Co-Host for any claims to the extent they arise solely based
          upon the combination, operation or use of any Product with equipment,
          data or programming not supplied by NAI, or to the extent they arise
          solely based upon the alteration or modification of the Products by
          the Co-Host or the purchaser of such Products.

11.  FORCE MAJEURE. Neither party shall be liable for the failure to perform any

12.  GENERAL.

     (a)  This Agreement, the Web Site Services Agreement and the certain ESD

          with or without reason or cause, unless this Agreement states
          otherwise.

     (c)  The parties agree that the terms and conditions of this Agreement
          shall prevail over any contrary or additional terms in any purchase
          order (unless agreed to in writing by both parties), sales
          acknowledgment, confirmation or any other document issued by either
          party affecting the purchase and/or sale of Goods. The terms of the
          Exhibits to this Agreement shall be equal in importance to the terms
          of the body of this Agreement.

     (d)  Either party's failure or delay in exercising any of its rights will
          not constitute a waiver of such rights unless expressly waived in
          writing. Neither party may assign this Agreement without the other's
          prior written approval, except by operation of law or in connection
          with the sale of substantially all of the assets of such party's
          business or the acquisition of such party by a third party.

     (e)  This Agreement will be governed and interpreted according to the laws
          of the State of California, without reference to principles of
          conflicts of laws. Each party hereto expressly consents to the
          personal jurisdiction of the state and federal courts located in Santa
          Clara County, California, and expressly waives any defense to any
          action based on inconvenient forum, choice of venue, lack of personal
          jurisdiction, sufficiency of service of process or the like.

     (f)  In the event of any litigation or arbitral proceeding between they
          parties regarding this Agreement, the advertising materials or the
          obligations of the parties hereunder, the party not prevailing therein
          shall pay the reasonable attorneys' fees and court costs of the party
          prevailing therein.

     (g)  If a court of law finds any provision of this Agreement unenforceable,
          the parties agree to modify such provision to the extent necessary to
          make it legal and enforceable while preserving its intent and the
          economic effect of the unenforceable provision.

     (h)  Any notices and demands provided hereunder must be in writing and will
          be deemed given upon the earlier of actual receipt or two (2) days

                                   EXHIBIT "E"

                              DISTRIBUTION ADDENDUM

     WHEREAS, NAI owns and/or markets certain computer software and hardware
products set forth on Exhibit "A" ("Products").

     WHEREAS, Co-Host is an independent reseller of computer products to end
users ordering products through web sites on the Internet operated by Co-Host.

     WHEREAS, Co-Host distributes electronic copies of the Products pursuant to
the ESD Agreement.

     WHEREAS, Co-Host desires to distribute the Products and NAI desires to make
the Products available to Co-Host for further distribution.

     THEREFORE, in consideration of the foregoing, and of the mutual covenants
and agreements hereinafter set forth, NAI and Co-Host enter into the following
additional agreements regarding the Products:

1.   APPOINTMENT. NAI appoints Co-Host as a non-exclusive distributor of the
     Products to end users ordering the Products from the Destination or the
     Co-Host Site, and Co-Host accepts this appointment. Co-Host shall
     distribute the Products, as an independent reseller, at its own risk and
     expense and subject to any such prices, contractual terms and conditions as
     Co-Host may from time to time determine. Nothing in this Agreement shall
     prohibit Co-Host from distributing competing products in the Territory. The
     "Territory" as that term is used herein shall mean all countries in the
     world except countries to which export or re-export of any Product, or the
     direct products of any Product is prohibited by United States law without
     first obtaining the permission of the United States Office of Export
     Administration or its successor. Co-Host shall not have the right to assign
     or otherwise transfer this Agreement or any rights herein granted to any
     other person or entity, except by operation of law or in connection with
     the sale of all of its assets, or the acquisition of the Co-Host by a third
     party. Any such attempted assignment shall be void and the Agreement shall
     remain in effect.

2.   DISTRIBUTION. Co-Host has the right to market and distribute the Products
     subject to the license agreement that accompanies such Product. Co-Host may
     not engage in the rental of any of the Products. Co-Host shall not in any
     event remove from or obscure upon any Products any labels placed thereon by
     NAI containing statements of restrictions upon distribution, without the
     prior written consent of NAI. NAI reserves the right in its sole discretion
     and without liability to Co-Host to add additional Products, change the
     prices for the Products pursuant to Section 5, modify the Products, change
     the level of NAI's support for the Products and discontinue the
     availability of any Product. Any addition or deletion from the list of
     Products will be indicated by NAI's revision to the NAI price list, and NAI
     will use reasonable efforts to provide Co-Host with thirty (30) days notice
     prior to the effective date of such changes indicated on the NAI price
     list.



                                       2
<PAGE>   17

3.   MARKETING.

     (a)  General. Co-Host will use commercially reasonable efforts to market
          the Products it orders to the best of its ability, and to that end
          will (i) conduct marketing activities authorized by NAI, (ii) support
          special promotions initiated by NAI, and (iii) maintain a sound
          financial condition. Co-Host will conduct its business in a manner
          that reflects favorably upon the Products and NAI.

     (b)  Advertising; Use of Trademarks. Co-Host may advertise and promote the
          Products in a commercially reasonable manner and, subject to the
          provisions of Section 5 of the Co-Hosting Agreement, may use
          trademarks, service marks and trade names provided by NAI in
          connection therewith, provided that all such promotions and
          advertising will be consistent with NAI's general quality standards
          and the provisions of Section 5 of the Co-Hosting Agreement. Unless
          otherwise agreed upon in writing by NAI, Co-Host will submit each
          advertisement and promotion to NAI for trademark review and approval
          prior to initial release, which approval will not be unreasonably
          delayed or withheld. All such usage which was not expressly approved
          by NAI must be terminated immediately upon receipt of notice from NAI
          to that effect.

     (c)  Trademarks Rights. NAI owns any and all trademarks, trade names, and
          service marks for the Products (as noted in Section 5 of the
          Co-Hosting Agreement). Such trademarks, trade names, and service marks
          shall include all product names, the names "Network Associates,"
          logos, designs, and other designations or brands used by NAI in
          connection with the Products. Co-Host acknowledges and agrees that NAI
          is not granting to Co-Host any rights in any Product trademark, trade
          name, or service mark in or outside of the Territory.

4.   INSPECTIONS, RECORDS AND REPORTING.

     (a)  Sales Out Reports. Co-Host will provide to NAI within ten (10) days
          after the end of each calendar month, a computer media data file in
          the format established by NAI showing, for such month, Co-Host's total
          sales, by customer and by Product from each location. If requested by
          NAI, Co-Host shall provide such reports with respect to weekly periods
          or bi-weekly periods prior to the end of the calendar month in which
          such period occurs.

     (b)  Inventory Level Reports. Co-Host will provide to NAI on Monday of each
          week, a computer media data file in the format established by NAI
          showing Co-Host's current inventory levels of each Product (including
          items in transit), and weekly runrate snapshots and the other
          information reasonably requested by NAI.

     (c)  Records. For three (3) years after each calendar quarter during the
          term of this Agreement, Co-Host will keep, at Co-Host's office, full
          and accurate books of account and copies of all documents and other
          materials for such quarter relating to this Agreement and Co-Host's
          records, accounts and contracts relating to the distribution of the
          Products.



                                       3
<PAGE>   18

     (d)  Audit. NAI may inspect the records described in Sections 4(c) upon
          demand from time to time. In addition, Co-Host agrees to allow NAI's
          independent auditors to audit and analyze appropriate accounting
          records of Co-Host from time to time (but not more than one every six
          (6) months) to ensure compliance with all terms of this Agreement. Any
          such audit shall be permitted by Co-Host within fifteen (15) days of
          Co-Host's receipt of NAI's written request to audit, during normal
          business hours. The cost of such an audit will be borne by NAI unless
          a material discrepancy indicating inadequate record keeping or that
          additional fees due to NAI are discovered, in which case the cost of
          the audit shall be borne by Co-Host. A discrepancy shall be deemed
          material if it involves payment or adjustment of more than five
          percent of the amount reported in favor of NAI. Audits and inspections
          shall not interfere unreasonably with Co-Host's business activities.]

5.   ORDERING AND PAYMENT.

     (a)  [*] Any order for delivery of physical product placed with NAI is [*]
          within [*] following receipt by NAI. NAI may [*] and unless NAI [*],
          the order is considered [*] only to the extent it is [*].] The terms
          and conditions of this Agreement and of the applicable NAI invoice or
          [*] will apply to each order [*] by NAI. Electronic confirmation from
          an authorized NAI email address shall have the same effect as [*]. The
          provisions of Co-Host's form of purchase order or other business forms
          will not apply to any order notwithstanding [*] of such order.

     (b)  Price to Co-Host. NAI will inform Co-Host as to its current suggested
          retail price of the Products and standard discount or pricing granted
          to NAI's traditional product distributors. During the term of this
          Agreement, Co-Host will be invoiced on the basis of [*] set forth on
          Exhibit "A" of this Distribution Addendum. [*] suggested retail price
          (SRP) for standard NAI Products shall exclude tradeups, upgrade SKUs
          and special promotions, unless otherwise indicated. NAI may change its
          SRP from time to time upon written notice to Co-Host, which may take
          the form of a revised price list, and NAI may notify Co-Host of a
          different [*] SRP in the event NAI offers special promotional SRPs or
          Product prices in NAI's discretion.

     (c)  Price Increase. If NAI increases its suggested retail price for any
          Product (a product upgrade with a different part number will not be
          the same Product) and there is a resulting increase in the price of
          Products to Co-Host, NAI will give Co-Host thirty (30) days advance
          notice of the effective date of any such increase and:

          (i)  NAI will honor the old price for any shipments of such Product
               already in transit to Co-Host;

 omitted and filed separately with the Securities and Exchange Commission.


                                       4
<PAGE>   19

          (ii) All additional orders following such thirty (30) day period will
               be shipped at the new price;

         (iii) NAI has orders for such Product from Co-Host already booked into
               NAI's order entry system at the time of such price increase or if
               Co-Host orders additional Products during such thirty (30) day
               period, then the price increase will not apply to [*] which call
               for [*] of [*] of such [*] the [*]; and

          (iv) Orders for such Product in NAI's order entry system [*] will be
               shipped at the new price unless they are canceled by Co-Host by
               written notice to NAI, provided that such notice is received by
               NAI no later than [*] prior to the date of shipment specified in
               such order.

     (d)  Price Decrease. If NAI decreases its suggested retail price for any
          Product (a product upgrade with a different part number will not be
          the same Product), the decrease will apply to [*] of such [*] and [*]
          to [*] that are in an [*] as of the [*] provided that [*] had been [*]
          no more than [*] prior to such effective date. To be eligible for such
          [*], Co-Host must deliver to NAI written evidence, signed by [*], of
          [*] of such [*] showing the [*] of each [*] for which [*] within [*]
          of receiving notice of such [*]. Such [*] will constitute [*] from NAI
          under this Agreement (unless the Agreement has terminated or expired
          in which case such [*] will be [*] to the extent that Co-Host [*]) in
          an amount equal to the [*] between the [*] at which each such [*] was
          provided to [*] and the [*] then applicable for [*] hereunder.

     (e)  TAXES.

          (i)  All amounts payable by Co-Host to NAI under this Agreement are
               exclusive of any tax, withholding tax, levy, or similar
               governmental charge that may be assessed by any jurisdiction in
               or outside the Territory except income and similar taxes levied
               on and payable by NAI. Such taxes, withholding taxes, levies, and
               governmental charges (collectively "Taxes") include Taxes based
               on sales, use, excise, import or export values/fees, value-added,
               income, revenue, net worth, or may be the result of the delivery,
               possession, or use of the Products, the execution or performance
               of this Agreement or otherwise. Should any Taxes be due, Co-Host
               agrees to pay such Taxes and indemnify NAI for any claim for

<PAGE>   20

               such Taxes demanded. Co-Host shall make no deduction from any
               amounts owed to NAI for any Taxes. Co-Host covenants to NAI that
               all Products distributed hereunder will be in the ordinary course
               of Co-Host's business, and Co-Host agrees to provide NAI with
               appropriate information and/or documentation satisfactory to the
               applicable taxing authorities to substantiate any claim of
               exemption from any Taxes.

          (ii) For all Taxes paid by Co-Host, Co-Host shall provide to NAI
               within forty-five (45) days after the end of any quarter, a
               certificate of tax payment documenting the payment and amount of
               the Taxes paid during the preceding quarter.

6.   SHIPMENT, RISK OF LOSS AND DELIVERY.

          NAI, for Products which have been returned by end users as defective,
          or pursuant to the warranty stated in NAI's end user license. Such
          credit will be in an amount equal to the original invoice price less

          discretion, may supply to Co-Host, at no charge, any and all missing
          materials which are supposed to be provided with the current release
          of such Products or replace the entire Products in such situation.

     (c)  Discontinued Products. Co-Host may, during the term of this Agreement,
          obtain a credit for the price paid by Co-Host to be applied against

          discontinued Products will be counted and inspected at the Inspection
          Site by NAI's employee, and upon NAI's acceptance thereof (which will
          be a condition of Co-Host's eligibility for a credit hereunder) such
          Products will be promptly and completely destroyed or, if requested by
          NAI, such Products or any portion thereof will be returned to NAI as
          it directs. No Product shall be deemed discontinued if a later version
          of the Product is still being offered by NAI and end users may obtain
          the current version of such Product from NAI electronically at no
          additional charge.

     (d)  Freight. Co-Host will pay all costs (including freight) associated
          with the return of the Products to NAI and back to Co-Host as provided

     (b)  Co-Host acknowledges that some NAI Products hereto contain encryption
          and some are export restricted (the "Restricted Software") by the U.S.
          Department of Commerce's Bureau of Export Administration (BXA).
          Co-Host further acknowledges that for this reason, the export of such
          items may subject the Co-Host or its executives to fines and/or other
          severe penalties. Unless all required permits and/or approvals have
          been obtained, Co-Host shall not export or re-export the Restricted
          Software outside of the United States, whether directly or indirectly,
          and will not cause, approve or otherwise facilitate others such as
          agents, subsequent purchasers, licensees or any other third parties in
          doing so. The parties agree to cooperate with each other with respect
          to any application for any required licenses and approvals. However,
          Co-Host acknowledges it is their ultimate responsibility to comply
          with all export laws with respect to the Restricted Software and that
          NAI has no further responsibility after the initial sale to the
          Co-Host within the United States.
