     combination of Entrust Products or any part thereof with other hardware or

     Transfer Agreement where such infringement would not have arisen from the
     use of such Entrust Products or portion thereof standing alone; (ii)
     modification of the Entrust Products after the Effective Date where such
     infringement would not have occurred but for such modifications; or (iii)
     use by Entrust of the Entrust Products in a manner or for a purpose not

     function without infringing any third-party rights; or (ii) substitute

     $26,000,000 (twenty six million U.S. dollars) for all occurrences.


Section 8.07. Remedies Exclusive. The remedies set forth in Section 8.01 as
              ------------------  
limited by Section 8.06 and the rights arising under the Series B Stock Purchase

the entire liability of NTL (including its Affiliates) in respect of any claims
relating to intellectual property infringement and/or breach of warranty in
respect of title to Intellectual Property. Except as set forth in the SPA and
the indemnity pursuant to the provisions of Section 8.01, in no event shall NTL
