Indemnification.

<PAGE>   6
     Hardware and Software components and Documentation) infringes a patent,
     trademark, copyright or service mark or constitutes theft or misuse of a
     trade secret owned or controlled by a third party, Vendor shall defend that
     action at its expense and shall pay any costs and damages awarded against

     System, or any component thereof, or if in Vendor's opinion the System is
     likely to become the subject of a claim of infringement, Vendor shall, at

     using the System or any component thereof consistent with the purchase and
     licensing right accorded Zeneca herein, or replace or modify the System or
     any component thereof so that it becomes non-infringing (but is otherwise
     substantially identical to the originally provided System and is also
     suitable for Zeneca's intended uses), or grant Zeneca a credit for the
     infringing System or component thereof. Vendor shall not have any liability
     to Zeneca if the alleged infringement is caused by use or sale of the item
     in combination with other products or devices which are not furnished by
     Vendor.

6.2  Each party agrees to indemnify, defend and hold the other party harmless
     from and against any claim, demand, action, penalty, suit or liability

     and internal counsel expenses), which the other party may hereafter incur,
     become responsible for, or pay out as a result of death or bodily injuries
     to any person, destruction or damage to any property caused by

     (a)  the breach of any term, warranty, representation or provision of this
          Agreement, or

     (b)  in the case of Vendor, any failure to warn of damages or defects in
          the System or any component thereof.

     Notwithstanding the foregoing, either party shall not be obligated to
     indemnify or hold harmless the other party against any losses, claims or
     suits caused solely by the willful misconduct or negligence of the other
     party.

     Location to be certified, Vendor shall provide an engineer for such visits
     at Zeneca's expense. Installation cannot be started until a completed site
     acceptance form (Exhibit F) has been received by Zeneca. Commitment dates
     will be adjusted to allow for days lost due to site facilities being
     unavailable.

Indemnification.

6.1   Third Party Infringement.  If notified promptly in writing of any action
      brought against Zeneca or the Zeneca Group alleging that Zeneca's sale,
      use or other disposition of the System (including

                                       5

<PAGE>   6
     Hardware and Software components and Documentation) infringes a patent,
     trademark, copyright or service mark or constitutes theft or misuse of a
     trade secret owned or controlled by a third party. Vendor shall defend that
     action at its expense and shall pay any costs and damages awarded against
     Zeneca in the action, including external attorney's fees and internal
     counsel expenses, provided that Vendor shall have control of the defense of
     any such action and all negotiations for its supplement or compromise, and
     provided further that no settlement will be made that is contrary to the
     best interests of Zeneca, as may reasonably be determined by Zeneca. If a
     final injunction is obtained in such action against Zeneca's use of the
     System, or any component thereof, or if in Vendor's opinion the System is
     likely to become the subject of a claim of infringement, Vendor shall, at
     its option and expense, either  procure for Zeneca the right to continue
     using the System or any component thereof consistent with the purchase and
     licensing right accorded Zeneca herein, or replace or modify the System or
     any component thereof so that it becomes non-infringing (but is otherwise
     substantially identical to the originally provided System and is also
     suitable for Zeneca's intended uses), or grant Zeneca a credit for the
     infringing System or component thereof. Vendor shall not have any liability
     to Zeneca if the alleged infringement is caused by use or sale of the item
     in combination with other products or devices which are not furnished by
     Vendor.

6.2  Each party agrees to indemnify, defend and hold the other party harmless
     from and against any claim, demand, action, penalty, suit or liability
     (including the cost of defense, settlement, and external attorney's fees
     and internal counsel expenses), which the other party may hereafter incur,
     become responsible for, or pay out as a result of death or bodily injuries
     to any person, destruction or damage to any property caused by

     (a)  the breach of any term, warranty, representation or provision of this
          Agreement, or

     (b)  in the case of Vendor, any failure to warn of damages or defects in
          the System or any component thereof.

     Notwithstanding the foregoing, either party shall not be obligated to
     indemnify or hold harmless the other party against any losses, claims or
     suits caused solely by the willful misconduct or negligence of the other
     party.

8.2  SOFTWARE UPGRADES/UPDATES.  Commercially released updates to all Zeneca
     licensed Software modules shall be provided at no charge without limitation

     Warranty Period may be purchased at Vendor's then listed price.

8.3  COMPUTER UPGRADES.  Hardware required for enhanced performance may be
     purchased from Vendor at the time of purchase. Zeneca may choose to upgrade
     the original computer hardware equipment after the initial installation:

     available a qualified engineer (at no additional charge) for the purpose of
     inspecting the Installation Location. The engineer shall conduct a series
     of standard measurements where required. If these measurements and the site
     facilities meet Vendor's site requirements, the engineer shall certify in
     writing on the form attached hereto as Exhibit F that the Installation
     Location is properly designed and equipped, and that the System will
     perform according to the Specifications (attached hereto as Exhibit C) and
     the Documentation in the environment. If the Installation Location does not
     meet Vendor's site requirements, the engineer shall make  specific written
     recommendations to Zeneca's engineering and building operations staff as to
     how the Installation Location can be made to meet Vendor's site
     requirements and Zeneca shall promptly implement such recommendations. If
     multiple site inspection visits are necessary in order for the Installation
     Location to be certified, Vendor shall provide an engineer for such visits
     at Zeneca's expense. Installation cannot be started until a completed site
     acceptance form (Exhibit F) has been received by Zeneca. Commitment dates
     will be adjusted to allow for days lost due to site facilities being
     unavailable.

                                   ARTICLE 9

DOCUMENTATION.  Vendor shall supply one (1) printed copy and one (1) electronic

          to compensate Vendor pursuant to paragraph 2.2 as of the effective
          date of termination. The other terms of this Agreement shall survive
