                      obligation or liability in relation thereto by reason or
                      arising out of the Investments being charged to the Lender
                      under this Debenture;

           Charges) take such steps as it considers appropriate to procure the
           performance of such obligations (without being deemed to be a
           mortgagee in possession) (including taking out or renewing any
           insurance or effecting such repairs and taking such other action as
           it may deem appropriate to remedy such failure) and recover the
           premiums and other expenses so incurred from the Company on demand

                      procedures stipulated by the Lender);

                      Indebtedness or to the crystallisation of the floating

                      debts due owing and unpaid at the time of and subsequent
                      to such release;

           (e)        if required by the Lender at any time, execute and deliver
                      to the Lender a legal assignment of such book debts and
                      other debts for the time being charged by Clause 2.2(e) of
                      this Debenture to the Lender in such form as the Lender
                      may require and give notice of such assignment to the
                      person from whom such book debts and other debts are due
                      in such form as the Lender may require; and

           (f)        authorise provision by the Bank to the Lender at any time
                      requested by the Lender for statements and particulars of
                      the Designated Account and such other financial and other
                      information in respect thereof as the Lender shall
                      require.

5          RECEIVER

5.1        At any time after the occurrence of an Event of Default (or if so
           requested by the Company), the Lender may demand repayment of the

           (c)        to sell,  let and/or  terminate or to accept  surrenders

           accepting or agreeing to accept surrenders of leases or tenancies of
           any part of the Property may be exercised by the Company without the
           Lender's prior written consent. Section 93 of the Law of Property Act
           1925 shall not apply.

6.2        The Company at its expense shall at any time at the Lender' request
           promptly execute and deliver to the Lender any other or further
           mortgage, charge or other instrument conferring a fixed charge on any
           of its Assets (including any of the Assets charged by Clause 2.2(j))
           or such other charge as the Lender may in its discretion think fit
           for securing the Indebtedness.

6.3        This Debenture shall be:

           (a)        a  continuing  security,  notwithstanding  any settlement
                      of account or other matter or thing whatever;

           (b)        without prejudice and in addition to any other security
                      for the Indebtedness (whether by way of mortgage,
                      equitable charge or otherwise) which the Lender may hold
                      now or hereafter on all or any part of the Assets;

           (c)        in addition to any rights, powers and remedies at law;

           (d)        apply to the ultimate balance of the Indebtedness
                      (together with all expenses whatever incurred by the
                      Lender in the enforcement or attempted enforcement of this
                      Debenture) and shall not be discharged or otherwise
                      affected by any intermediate payment or satisfaction of
                      any part of the Company's obligations;

6.4        Any release or discharge of this Debenture shall be conditional on no
           payment or assurance received by the Lender in respect of the
           Company's obligations under the 


                                      -7-


           Facility Agreement being avoided or reduced under any law (English or
           foreign) relating to bankruptcy, liquidation or analogous
           circumstances in force within the relevant period after that payment
           or discharge during which any payment may for any reason be reclaimed
           or otherwise not retained by the Lender. After that avoidance or
           reduction, the Lender may exercise its rights under the Facility
           Agreement and this Debenture and/or any other rights which it would
           have been entitled to exercise notwithstanding any release and
           discharge which shall be considered null and void. In this Clause
           6.4, the "relevant period" means the relevant statutory period,
           extended by one month, within which any payment or security made to

           statutory power of sale shall be exercisable at any time after the
           execution of this Debenture. The Lender shall not exercise its power
           of sale until payment has been demanded, but this provision shall not
           affect a purchaser or put him on inquiry whether such demand has been
           made.

6.6        No failure or delay on the Lender's part in the exercise of any of
           its rights, powers and remedies (in this Clause 6 "right(s)") under
           this Debenture or at law shall operate or be construed as a waiver.
           No waiver of any of the Lender's rights shall preclude any further or
           other exercise of that right or of any other right.

6.7        The Lender may give time or other indulgence or make any other
           arrangement, variation or release with any person in respect of the
           Indebtedness or any other security or guarantee for the Indebtedness
           without derogating from the Company's liabilities or the Lender's
           rights under this Debenture.

6.8        The Company certifies that this Debenture is in its best commercial
           interests and does not contravene its Memorandum and Articles of
           Association or any agreement binding on it or on any of the Assets
           and has been executed in accordance therewith and hereby applies to
           the Chief Land Registrar for a restriction to be entered on the
           register of its title to registered properties charged by this
           Debenture that:

                      "Except under an Order of the Registrar no disposition or
                      dealing by the proprietor of the land is to be registered
                      or noted without the consent of the proprietor for the
                      time being of Charge No ."

6.9        A certificate signed on behalf of the Lender of the amount for the
           time being of any Indebtedness and/or the amounts due to the Lender
           shall be conclusive evidence for all purposes against the Company,
           unless manifestly incorrect.

6.10       No person dealing with a Receiver or the Lender shall be concerned to
           enquire 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 Lender. All the protection to
           purchasers contained in Sections 104 and 107 of the Law of Property
           Act 1925 shall apply to any person purchasing from or dealing with a
           Receiver or the Lender.
