10.1     ENTRY, POSSESSION AND POWER TO REMEDY

         The Company shall upon 5 days prior notice (except if an Enforcement
         Event has occurred and is continuing, when no prior notice shall be
         required) permit the Security Trustee and/or its representatives,
         agents or contractors free access at reasonable times to enter or take

                  to remedy any failure to comply with any covenant contained in
                  Clause 9 (Specific Covenants),

         and in any such case without becoming liable to account as mortgagee in
         possession;

         provided, however, that the Security Trustee acknowledges that, in
         exercising the rights and privileges conferred in this Clause 10.1, it
         or agents, representatives or contactors may, from time to time, obtain
         knowledge of information, practices, books, correspondence and records
         of a confidential nature and in which the Company has a proprietary
         interest. The Security Trustee agrees that all such information,
         practices, books, correspondence and records are to be regarded as
         confidential information and agrees that it shall retain in strict
         confidence and shall use its reasonable efforts to ensure that its
         agents and representatives retain in strict confidence, and will not
         disclose without the prior written consent of the Company, any such
         information, practices, books, correspondence and records furnished to
         them except that the Security Trustee may disclose such information (i)
         to its officers, directors, employees, agents, legal advisers,
         accountants, auditors, affiliates, advisors or representatives
         (provided that such persons are informed of the confidential nature of
         such information), (ii) to the extent such information has become
         available to the public other than as a result of a disclosure by or
         through the Security Trustee or its officers, directors, employees,
         agents, legal advisers, accountants, auditors, affiliates, advisors or
         representatives, (iii) to the extent such information was available to
         the Security Trustee on a non-confidential basis prior to its
         disclosure to the Security Trustee hereunder, (iv) to the extent the
         Security Trustee is (A) required in connection with any legal or
         regulatory proceeding or (B) requested by any bank or other regulatory
         authority to disclose such information; (v) to any prospective assignee
         of any note or other instrument evidencing any of the Secured
         Liabilities; provided, however, that the Security Trustee shall notify
         such assignee of the confidentiality provisions of this Section 10.1
         and such assignee shall agree to be bound thereby; or


                                      -21-

         (vi) to any Bank, subject to the confidentiality provisions contained
         in this Debenture and the Credit Agreement and any other Loan Documents
         to which it is a party, upon the request of such party following the
         occurrence and during the continuance of any Event (but with no
         obligation on the part of any such Bank to return such information to
         the Security Trustee or the Company if any such Enforcement Event is
         subsequently cured or waived).

 10.2    INSURANCES

         If the Company shall fail to comply with any of its obligations as to
         insurance, the Security Trustee may, but shall not be required to, take
         out, renew or maintain such insurance either in its own name, in its
         name and that of the Company jointly or in the name of the Company with
         the Security Trustee's interest noted on the policy, in such sum as the
         Security Trustee may think expedient.

10.3     INDEMNITY

         The Company shall on demand indemnify the Security Trustee and the
         Banks on a full indemnity basis in respect of any and all costs,
         damages and expenses incurred by the Security Trustee or the Banks

         Trustee and the Banks on a full indemnity basis in respect of any and

         and expenses arising as a result of any breach of Clause 9 (Specific
         Covenants) or otherwise relating to all or any part of the Secured
         Assets save to any costs, charges or expenses incurred as a result of
         the Security Trustee's own negligence or wilful default.

         No purchaser, mortgagee or other person dealing with a Receiver or the

         to require that any such monies be applied in or towards making good
         the loss or damage in respect of which they became payable.

         Trustee consider expedient.

         15.1 (Appointment) is as regards each of the Security Trustee and each

         the Company to the Security Trustee or received by the Security Trustee

         been credited to the new account and shall not operate to reduce the
         amount secured by this Debenture at the time when the Security Trustee
         received or was deemed to have received such notice or, as the case may

                  on account of the liability of any third party:

                  (i)      be subrogated to any rights of, or security or monies
                           held, received or receivable by, the Security Trustee
                           or the Banks or be entitled to any right of

                  benefit of any security received by it in breach of this
                  Clause 16.4. If the Company exercises any right of set-off

                                      -30-

<PAGE>

                  contrary to the above, it will immediately pay an amount equal

         receipts or be liable to the Company for any loss or damage arising

         Part VI of the Insolvency Act 1986 or similar legislation binding on
         the Company in a jurisdiction other than England and Wales and no
         release, settlement, discharge or arrangement given or made by the
         Security Trustee on the faith of any such assurance, security or
         payment shall prejudice or affect the right of the Security Trustee or
         the Banks to recover from the Company and from the Security the Secured
         Liabilities (including any monies which it may have been compelled by
         due process of law to refund under the provisions of the Insolvency Act
         1986 and any costs payable by it pursuant to or otherwise incurred by
         it in connection with such process).

17.2     REINSTATEMENT

         If any payment by the Company or any discharge given by the Security
         Trustee or any Bank (whether in respect of the obligations of the
         Company or any Security Interest for those obligations or otherwise) is
         avoided or reduced as a result of Dissolution:

         (a)      the liability of the Company shall continue as if the payment,
                  discharge, avoidance or reduction had not occurred; and

         (b)      the Security Trustee and/or the Banks, as the case may be,
                  shall be entitled to recover the value or amount of that
                  Security Interest or payment from the Company, as if the
                  payment, discharge, avoidance or reduction had not occurred.

18.      CUSTODY

         The Security Trustee shall be entitled to provide for the safe custody
         by third parties of all certificates and documents of title relating to
         the Secured Assets and shall not be responsible for any loss or damage
         occurring to or in respect of the same unless such loss or damage
         arises as a result of the Security Trustee's negligence or wilful
         misconduct.


                                      -31-

<PAGE>

19.      DELEGATION

         The Security Trustee may at any time and from time to time delegate by
         power of attorney or in any other manner to any persons or persons all
         or any of the powers, authorities and discretions which are for the
         time being exercisable by the Security Trustee under this Debenture in
         relation to all or any part of the Secured Assets. Any such delegation
         may be made upon such terms (including power to sub-delegate) and
         subject to such conditions as the Security Trustee may think fit. The
         Security Trustee shall not be in any way liable or responsible to the
         Company for any loss or damage arising from any act, default, omission
         or misconduct on the part of any such delegate or sub-delegate. Such
         delegation shall not preclude the subsequent exercise of such powers,
         authorities and discretions by the Security Trustee itself nor preclude
         the Security Trustee from making a subsequent delegation of the same to
         another person or from revoking any such delegation.

20.      PRIOR CHARGES

         In the event of there being a prior Security Interest to the Security
         and proceedings or steps being taken to exercise or enforce any powers
         or remedies conferred by such prior Security Interest against all or
         any of the Secured Assets, the Security Trustee or any Receiver
         appointed under this Debenture in respect of such Secured Assets may
         (but without prejudice to any rights the Receiver may have under
         Section 43 of the Insolvency Act 1986 to apply to a court for
         authorisation to dispose of property secured by a prior Security
         Interest) redeem such prior Security Interest or procure its transfer
         to itself or such Receiver, as the case may be, and may settle and pass
         the accounts of any prior mortgagee, chargee or encumbrancer. Any
         account so settled and passed shall be conclusive and binding on the
         Company and all the principal, money, interest, costs, charges and
         expenses of and incidental to such redemption or transfer shall be paid
         to the Security Trustee on demand together with interest at the Default
         Rate on the same from the earlier of the date of demand and the date of
         payment by the Security Trustee until the date of payment by the
         Company, whether before or after judgment. All the powers, authorities
         and discretions conferred by a prior Security Interest upon any prior
         mortgagee, chargee or encumbrancer or any receiver under such prior
         Security Interest shall be exercisable by the Security Trustee or a
         Receiver in a like manner as if the same were expressly included in
         this Debenture and the Security Trustee or such Receiver shall be
         entitled to exercise all the powers, authorities and discretions of a
         receiver, receiver and manager or administrative receiver appointed
         under such prior Security Interest.

21.      SET-OFF

         Without prejudice to any rights the Security Trustee may have at law,
         in equity or otherwise, following an Enforcement Event, the Security
         Trustee or the Banks may, without notice to the Company, combine or
         consolidate all or any sums standing to the credit of the Company's
         accounts with the Security Trustee or the Banks with the Secured
         Liabilities and/or set-off or transfer any such sums in or towards the
         satisfaction of any of the Secured Liabilities and may do so
         notwithstanding that the balances on such accounts and such Secured
         Liabilities may not be expressed in the


                                      -32-

         purpose of exercising any rights under this Clause or applicable law
         the Security Trustee or the Banks is authorised to effect any necessary
         conversions at the Security Trustee or the Banks' own rate of exchange
         then prevailing. Neither the Security Trustee nor the Banks shall be
         obliged to exercise any right given to it by this Clause.

22.      CURRENCY INDEMNITY

         If any sum due from the Company under this Debenture or any order or
         judgment given or made in relation to this Debenture has to be
         converted from the currency (the "FIRST CURRENCY") in which the same is
         payable into another currency (the "SECOND CURRENCY") for the purpose
         of (a) making or filing a claim or proof against the Company, (b)
         obtaining an order or judgment in any court or other tribunal, (c)
         enforcing any order or judgment given or made, or (d) applying the same
         in satisfaction of any of the Secured Liabilities, the Company shall,
         as a separate and independent obligation, indemnify and hold harmless
         the Security Trustee or the Banks from and against any loss suffered as
         a result of any discrepancy between (i) the rate of exchange used for
         such purpose to convert the sum in question from the first currency
         into the second currency and (ii) the rate or rates of exchange at
         which the Security Trustee or the Banks may in the ordinary course of
         business purchase the first currency with the second currency upon
         receipt of a sum paid to it in satisfaction, in whole or in part, of
         any such order, judgment, claim or proof or for application in
         satisfaction of the Secured Liabilities.

                          GOVERNING LAW AND ENFORCEMENT

35.      GOVERNING LAW

         This Debenture is governed by English law.

36.      ENFORCEMENT

36.1     JURISDICTION OF ENGLISH COURTS

         (a)      The courts of England have exclusive jurisdiction to settle
                  any dispute arising out of or in connection with this
                  Debenture (including a dispute regarding the existence,
                  validity or termination of this Debenture) (a "DISPUTE").

         (b)      The Parties agree that the courts of England are the most
                  appropriate and convenient courts to settle Disputes and
                  accordingly no Party will argue to the contrary.

         (c)      This Clause 36.1 is for the benefit of the Security Trustee
                  and the Banks only. As a result, neither the Security Trustee
                  nor the Banks shall be prevented from taking proceedings
                  relating to a Dispute in any other courts with jurisdiction.
                  To the extent allowed by law, the Security Trustee or the
                  Banks may take concurrent proceedings in any number of
                  jurisdictions.
