                      Intellectual Property which is material to its business or
                      which are necessary to renew or otherwise maintain the
                      registered status and validity of any such Intellectual

                      Intellectual Property which is material to its business,
                      or if it receives notification of any alleged or suspected
                      infringement of any third party's trade marks or other
                      intellectual or other rights arising from the use of any

                      sub-Clause or for the defence of any legal proceedings
                      brought by any third party relating to or affecting the
                      Intellectual Property which is material to its business
                      and it shall not settle or compromise any such proceedings
                      without first obtaining the consent of the Security
                      Trustee (such consent not to be unreasonably withheld or
                      delayed).

                      which will or may be to materially and detrimentally
                      affect the value of any of such Intellectual Property; and

               (vi)   do or cause or permit to be done anything which may in any

11.     POWERS OF LEASING

11.1    Prohibition on Exercise of Powers by a Company

        Following an Event of Default which is subsisting, each Company shall
        neither exercise the powers of leasing or accepting surrenders of leases
        conferred upon a mortgagor in possession by Sections 99 and 100 of the
        LPA nor any other powers of leasing, surrendering or accepting
        surrenders of leases vested in such Company nor shall such Company
        confer on any Person any contractual licence to occupy or any other
        right or interest in any of its property or grant any licence or consent

        entitled to require that an order be obtained under Section 38(4) of the

        of that Act as a pre-condition to the granting of any lease.

11.2    Powers of Security Trustee

        In addition to the powers of leasing or accepting surrender of leases
        conferred on mortgagees by Sections 99 and 100 of the LPA, the Security
        Trustee may at any time after the occurrence of an Event of Default and
        provided that such Event of Default is continuing on such terms as it
        shall in its absolute discretion think fit:

        (a)    grant or make any agreement for any lease of the Secured Property
               or of any part thereof for any term or terms of years either in

               thereof,

        in each case without the restrictions contained in Sections 99 and 100
of the LPA.

12.     ENFORCEMENT

12.1    Event of Default

        If an Event of Default has occurred and is continuing then the security
        hereby constituted shall become immediately enforceable and the power of
        sale and other powers conferred by Section 101 of the LPA as varied or
        extended by this Debenture shall become immediately exercisable without
        the restrictions contained in the LPA as to the giving of notice or
        otherwise.

12.2    Exclusion of Provisions of LPA

        The Secured Obligations shall be deemed for the purposes of all powers
        implied by statute to have become due and payable within the meaning of

        and Section 103 of the LPA (restricting the power of sale) Section 109
        of the LPA (restricting the power to

                                      -31-
<PAGE>

        appoint a receiver) and Section 93 of the LPA (restricting the right of
        consolidation) shall not apply to this Debenture or any security given
        pursuant to this Debenture.

12.3    Consolidation

        The restriction on the consolidation of mortgages imposed by Section 93
        of the LPA shall not apply to this Debenture or to any security given to

12.4    Powers of Mortgagee

        The powers conferred on mortgagees or receivers or administrative
        receivers by the LPA and the Insolvency Act 1986 (as the case may be)
        shall apply to the security constituted by this Debenture except insofar
        as they are expressly or impliedly excluded and where there is ambiguity
        or conflict between the powers contained in such Acts and those
        contained in this Debenture, then this Debenture shall prevail.

12.5    Power of Sale

        The statutory power of sale exercisable by the Security Trustee under
        this Debenture is hereby extended so as to authorise the Security
        Trustee to sever any fixtures from the property to which they are
        attached and sell them separately from such property.

12.6    Exercise of Powers

        All or any of the powers conferred upon mortgagees by the LPA as hereby
        varied or extended and all or any of the rights and powers conferred by
        this Debenture on a Receiver (whether expressly or impliedly) may be
        exercised by the Security Trustee without further notice to any Company
        at any time after this security shall have become enforceable and the
        Security Trustee may exercise such rights and powers irrespective of
        whether the Security Trustee has taken possession or has appointed a
        Receiver of the Secured Property.

13.     PROTECTION OF THIRD PARTIES

13.1    Protection of Third Parties

        No purchaser, mortgagee or other Person dealing with a Receiver or the
        Security Trustee shall be concerned to enquire whether the Secured
        Obligations have become payable or whether any power which he or it is
        purporting to exercise has become exercisable or whether any money is
        due under this Debenture or as to the application of any money paid,
        raised or borrowed or as to the propriety or regularity of any sale by
        or other dealing with such Receiver or the Security Trustee. All the
        protection to purchasers contained in Sections 104 and 107 of the LPA
        shall apply to any Person purchasing from or dealing with a Receiver or
        the Security Trustee as if the Secured Obligations had become due and
        the statutory powers of sale and of appointing a Receiver in relation to
        the Secured Property had arisen on the date of this Debenture.

                                      -32-
<PAGE>

13.2    Receipts Conclusive

        The receipt of the Security Trustee or any Receiver shall be an absolute
        and a conclusive discharge to a purchaser and shall relieve him of any
        obligation to see to the application of any moneys paid to or by the
        direction of the Security Trustee or any Receiver.

13.3    Meaning of Purchaser

        In Clauses 13.1 (Protection of Third Parties) and 13.2 (Receipts
        Conclusive) "purchaser" includes any Person acquiring, for money or
        money's worth, any lease of, or Security Interest over, or any other
        interest or right whatsoever in relation to, the Secured Property.

14.     APPOINTMENT OF RECEIVER

14.1    Appointment

        At any time after the security constituted by this Debenture has become
        enforceable or if any Company so requests in writing at any time the
        Security Trustee may without further notice to such Company appoint by
        writing under hand of a duly authorised officer or under seal any one or
        more Persons qualified to act as a receiver, receiver and manager or
        administrative receiver (as the case may require) under the Insolvency
        Act 1986 either singly, jointly, severally or jointly and severally to
        be a Receiver of all or any part of the Secured Property of such Company
        and either at the time of appointment or any time thereafter may fix his

        remove any such Receiver and appoint another or others in his or their
        place.

14.2    Powers

        Any Receiver of a Company whether appointed solely or jointly shall have
        the powers granted by the LPA to any receiver appointed under it and all
        the powers of an administrative receiver under the Insolvency Act 1986
        and in addition shall have power to do the following:

        (a)    enter upon, take possession of, collect and get in the Secured
               Property in respect of which he may be appointed or any part of
