         Occupational Pensions Scheme (Deficiency on Winding-up etc) Regulations
         1996, being the debt due to the Scheme from PEL at Completion (being
         the time at which PEL ceased to be an "Associated Employer" in terms of
         Rule 34.1.5 of the Rules of the Pension Scheme) ("the Certificate").

         8.3 The Vendor and Intelek shall and the Purchaser shall procure that

                  the Purchaser;

         (b)      if the Certificate discloses that the amount of the debt due
                  from PEL to the Pension Scheme is less than the amount of the
                  Pension Retention the Solicitors shall instruct that the
                  balance of any monies after the payment to the trustees of the
                  Pension Scheme standing to the credit of the Retention Account
