                                    ARTICLE I
                                    SECURITY

Section 1.01. Performance and Obligations Secured. This Security Agreement is
given to secure the payment and performance of the Obligations (as such term is
defined in the Loan Agreement of even date herewith by and between Debtor and
Secured Party (the "Loan Agreement")). This Security Agreement shall also secure
any and all renewals or extensions of the whole or any part of the Obligations,
however evidenced, with interest at such lawful rate as may be agreed upon, and
any such renewals or extensions or any change in the terms or rate of interest
shall not impair in any manner the validity of or the priority of this Security
Agreement, nor release Debtor from liability for the Obligations. Reference is
hereby made to the Loan Agreement as if set out here at length and incorporated
herein.

                                   ARTICLE II
                     REPRESENTATIONS AND COVENANTS OF DEBTOR

Debtor represents, covenants and agrees with Secured Party as follows:

Section 2.01. Name; Formation. Debtor represents and warrants that it is a
corporation duly organized and validly existing under the laws of the State of
Delaware under the name of CTI Group (Holdings), Inc. Debtor's chief executive
office is at 333 N. Alabama Street, Suite 240, Indianapolis, Indiana 46255.

Section 2.02. Covenants of Title. Debtor warrants that it is lawfully possessed
of and has good and complete title to all the Collateral, free and clear of all
liens and encumbrances other than Permitted Liens (as defined in the Loan
Agreement).

Section 2.03. Covenant To Comply with Terms. Debtor will pay and perform all
Obligations, as the same become due, in accordance with its terms, without
relief from valuation or appraisement laws, and it will keep, observe and
perform all of the terms, provisions, covenants and agreements of this Security
Agreement and the Loan Agreement.

Section 2.04. Covenant To Maintain, Repair and Replace Collateral. Debtor will,
at all times, maintain, preserve and keep the Collateral in good repair, working
order and condition and will not commit or suffer any waste thereof, reasonable
wear and tear excepted.

Section 2.05. Covenants Regarding Possession of Collateral. Debtor or a
Guarantor (as defined in the Loan Agreement) shall have possession of the
Collateral, except where expressly otherwise provided in this Security Agreement
or where Secured Party chooses to perfect its security interest by possession in
addition to the filing of a financing statement. Where Collateral is in the
possession of a third party, Debtor will, upon request of Secured Party during
the continuance of an Event of Default, join with Secured Party in notifying the
third party of Secured Party's security interest and obtaining an acknowledgment
from the third party that it is holding the Collateral for the benefit of
Secured Party. Debtor will cooperate with Secured Party in obtaining control
with respect to Collateral consisting of deposit account, investment property,
letter of credit rights, and electronic chattel paper. Debtor will not create
any chattel paper without placing a legend on the chattel paper acceptable to
Secured Party indicating that Secured Party has a security interest therein.

<PAGE>

Section 2.06. Additional Covenants. Debtor covenants and agrees that Secured
Party shall have the right at any time during the continuance of an Event of
Default to enforce Debtor's rights against account debtors and obligors. Debtor
further acknowledges and agrees that Secured Party does not authorize, and
Debtor agrees not to, make any sales or leases of any of the Collateral, license
any of the Collateral, or grant any other security interest in any of the
Collateral other than Permitted Liens or as otherwise permitted by the Loan
Agreement. Until the Obligations are paid in full, Debtor agrees that it will
preserve its company existence and not, in one transaction or a series of
related transactions, merge into or consolidate with any other entity, or sell
all or substantially all of its assets, change the state of its organization, or
change its legal name without providing Secured Party with thirty (30) days
prior written notice.

Section 2.07. Security Agreement. This Security Agreement is intended to be a
security agreement pursuant to the UCC for any of the personal property and
fixtures described herein. Debtor agrees to execute and deliver, or cause to be
executed and delivered, to Secured Party UCC financing statements covering said
personal property and fixtures from time to time and in such form as Secured
Party may reasonably require to perfect or maintain the priority of Secured
Party's security interest with respect to said personal property and fixtures,
and Debtor shall bear all costs thereof. Debtor will not create or suffer to be
created any other security interest in said personal property and fixtures,
including replacements thereof and additions thereto, except for Permitted Liens
or as otherwise authorized pursuant to this Security Agreement. Upon the
occurrence and during the continuance of any Event of Default, Secured Party
shall have the remedies of a secured party under the UCC and, at Secured Party's
option, may also invoke the remedies provided herein with respect to such
property. Debtor further authorizes and appoints Secured Party its
attorney-in-fact, to execute and file on its behalf a financing statement or
statements in those public offices deemed necessary by the Secured Party and
authorizes Secured Party to file duplicates of any financing statements as
determined by Secured Party. Debtor will pay all filing fees for the filing of
this instrument or of financing statements filed to perfect the security
interest provided in this Security Agreement or in connection with this Security
Agreement.

promptly correct any defect or error which may be discovered in the contents of
this Security Agreement or in the execution or acknowledgment thereof; (ii)
execute, acknowledge, deliver and record or file such further instruments
(including without limitation further security agreements, financing statements

necessary, desirable or proper to carry out more effectively the purposes of
this Security Agreement and the Loan Agreement and to subject to the liens and
security interests hereof and thereof any property intended by the terms hereof
and thereof to be covered hereby and thereby including specifically, but without
limitation, any renewals, additions, substitutions, replacements, or
appurtenances to the Collateral; and (iii) execute, acknowledge, deliver,
procure and record or file any document or instrument (including specifically
any financing statement) deemed reasonably advisable by Secured Party to protect
the lien or the security interest hereunder against the rights or interests of
third persons, and Debtor shall pay all reasonable costs connected with any of
the foregoing.

Section 2.09. Termination. Upon complete and irrevocable satisfaction of the
Obligations, this Security Agreement shall terminate and be of no further force
and effect, and upon request of the Debtor, Secured Party shall release the
liens granted hereunder.

     INTELLECTUAL PROPERTY

9.2  The Company shall during the subsistence of the Security:

     (A)  promptly notify the Bank of the acquisition or creation of any
          Intellectual Property by the Company (whether by its officers,
          employees or otherwise) that may be or become relevant to the
          Company's business, take all steps necessary to ensure that such
          Intellectual Property is properly vested in the Company and, in the
          case of any such Intellectual Property which is capable of being
          protected by patent,

                                       21

          registered trade mark or registered design, promptly and at its own
          expense apply to the proper authority for registration thereof;

     (B)  take all steps necessary to ensure that the Charged Intellectual
          Property remains valid and subsisting including using its best
          endeavours to protect them from theft, attack, loss or destruction,
          unauthorised use, unauthorised copying or unauthorised access by any
          third party;

     (C)  use its reasonable endeavours to detect infringement of the Charged
          Intellectual Property and forthwith give notice (setting out all
          relevant details) to the Bank of any infringement of or challenge to
          the Charged Intellectual Property and at the direction of the Bank but
          at the cost of the Company take such steps as the Bank shall in its
          discretion reasonably direct in relation to any such infringement or
          challenge (including prosecuting or defending any proceedings).
          Subject to any such directions of the Bank, the Company shall not be
          precluded from taking such steps as it considers necessary or
          desirable in relation to any infringement of or challenge to the
          Charged Intellectual Property provided that the Company shall not
          grant any licence or concede the invalidity or unenforceability of any
          of the Charged Intellectual Property without the prior written consent
          of the Bank;

     (D)  without prejudice to the generality of the foregoing:

          (1)  pay all renewal fees, costs, taxes and other expenses which may

          (2)  only deal with the Charged Intellectual Property in the ordinary
               course of operating its business;

          (3)  not grant any licence or consent in respect of Intellectual
               Property (or agree or purport to agree to any of the foregoing)
               other than non-exclusive licences on arms' length commercial
               terms in the ordinary and usual course of and for the purposes of
               its business and subject to the other provisions of this clause
               9.2;

          (4)  keep confidential all trade secrets and other confidential
               information relating to its business or potential future business
               and not knowingly authorise or permit any steps or knowingly omit
               to take any steps which the Company knows or which it reasonably
               ought to know would be liable to result in the disclosure of any
               such information unless the person receiving such information is
               bound by written obligations of confidentiality no less stringent
               than the provisions contained in this clause 9.2(D)(4).

          (5)  not (whether by the doing of any act or the failure to do any
               act) abandon, cancel or allow to become void or lapse or to
               become liable to any attack (including but not limited to an
               attack for non-use) any of the Charged Intellectual Property and
               shall forthwith upon any of the Charged Intellectual Property
               becoming void or lapsing do all things and incur all expenses
               necessary to restore the same to the Company;

          (6)  promptly notify the Bank of any application to amend the
               specification drawings or claims of any of the patents or patent
               applications or any

                                       22

<PAGE>

               application to alter the specification of any of the trade or
               service marks or applications for the same forming part of the
               Charged Intellectual Property and not without the prior written
               consent of the Bank, which consent shall not unreasonably be
               withheld, enter into any conditions, restrictions or disclaimers
               in relation to any of the Charged Intellectual Property which is
               registered;

          (7)  not use or allow to be used, do any act or omit to do any act or
               enter into any arrangement with any third party in relation to,
               any of the Charged Intellectual Property in any manner which may
               materially adversely affect its value; and

          (8)  if the fixed or floating charge taken over the Charged
               Intellectual Property is not effective under local law in respect
               of any designation in any country outside the UK of European
               Patent EP 0 541 535 or any such designations of other European
               Patents owned by the Company from time to time (the "European
               Patents"), the Company agrees to grant such security in the
               country or countries concerned as may be permissible under local
               law over those designations of the European Patents, so as to
               permit a Receiver to exercise the powers in clause 15 of this
               Debenture in relation to all designations of the European Patents
               on the occurrence of an Enforcement Event.

     INVESTMENTS

9.3  The Company shall during the subsistence of the Security pay on the same
     becoming due all calls or other payments which may be or become due in
     respect of any of the Investments. If the Company fails to make any such
     payment, the Bank may if it thinks fit (it being acknowledged by the
     Company that the Bank will incur no liability to the Company if it does
     not) make such payment on behalf of the Company. The Company shall
     reimburse any sums so paid by the Bank to the Bank on demand and shall pay
     interest thereon from the date of payment by the Bank until such sums are
     reimbursed at the rate and otherwise as mentioned in clause 2.4.

     CONTRACTS

9.4  The Company shall during the subsistence of the Security:

     (A)  observe and perform, and remain liable to observe and perform, all the
          obligations on its part contained in and assumed by it under the
          Contracts (and the Bank shall be under no obligation by virtue of this
          Debenture in respect of any failure by the Company so to observe or
          perform such obligations);

     (B)  diligently pursue any remedies available to it in respect of any
          breach thereof or in respect of any claim arising thereunder or in
          relation thereto; and

     (C)  not, without the prior written consent of the Bank, such consent not
          to be unreasonably withheld, make or agree to make any amendment,
          waiver or release of, or determine, any of the Contracts or permit any
          breach or default thereof or thereunder to exist.

     DEBTS

9.5  The Company shall at all times during the subsistence of the Security:

                                       23

<PAGE>

     (A)  subject to any directions given in accordance with clause 9.8, get in
          and realise the Debts on behalf of the Bank and hold the proceeds of
          the getting in and realisation thereof (until payment into the
          Operating Accounts or, following the occurrence of an Enforcement
          Event, the Controlled Accounts or as the Bank may otherwise require as
          hereinafter provided) upon trust for the Bank;

     (B)  subject to clause 9.5(C), pay the proceeds of the getting in and
          realisation of the Debts (or such of them as the Bank may specify), or
          ensure that such proceeds are paid, into the Operating Accounts (or
          such of them as the Bank may specify);

     (C)  following the occurrence of an Enforcement Event and if the Bank shall
          so require in writing, pay the proceeds of the getting in and
          realisation of the Debts (or such of them as the Bank may specify), or
          ensure that such proceeds are paid, into the Controlled Accounts (or
          such of them as the Bank may specify) or as the Bank may otherwise
          require;

     (D)  unless the Bank otherwise agrees in writing (and then only on such
          terms and in such manner as the Bank may require) not be entitled to
          withdraw or transfer from the Controlled Accounts any moneys standing
          to the credit thereof or direct any payment to be made therefrom to
          any person; and

     (E)  in the event that any of the Operating Accounts or the Controlled
          Accounts are opened or maintained with a bank other than the Bank:

          (1)  permit and instruct such bank to furnish directly to the Bank
               from time to time upon request full statements and particulars of
               any Operating Accounts and any Controlled Accounts opened or
               maintained with such bank and such other financial statements and
               information with respect to the assets and liabilities of the
               Company as are from time to time available to such bank; and

          (2)  furnish to the Bank evidence satisfactory to the Bank that any
               bank with which any of the Controlled Accounts has been opened or
               is being maintained has been notified of, and has agreed to
               operate such account in accordance with, any procedures
               stipulated by the Bank.

9.6  Any proceeds of such getting in and realisation of the Debts received by
     the Company and paid, in accordance with clause 9.5(B), into any of the
     Operating Accounts shall upon such payment in (and provided that the
     Operating Account concerned is subject to the floating charge at the time
     of such payment in) stand released from any fixed security on such Debts
     created by this Debenture and shall instead stand subject to the floating
     charge. Any such release shall in no respects derogate from the subsistence
     and continuance of the fixed charges over and/or the assignments of all
     other Debts for the time being outstanding.

9.7  The Company will do everything necessary or that the Bank considers
     appropriate (including issuing written instructions to the debtors or other
     obligors) to ensure that such proceeds are paid directly or transferred
     into the Operating Accounts or the Controlled Accounts, or as the Bank may
     otherwise require, in accordance with clauses 9.5(B) and 9.5(C).

9.8  The Company shall at all times during the subsistence of the Security deal
     with the Debts in accordance with any directions from time to time given in
     writing by the Bank and in

                                       24

<PAGE>

     default of and subject to such directions shall not at any such time
     without the prior written consent of the Bank deal with the Debts otherwise
     than by getting in and realising the same in the ordinary and usual course
     of the Company's business. Without prejudice to the generality of the
     foregoing, the Company shall not at any such time without such a direction
     or consent compound, release, exchange, set-off, factor or discount the
     whole or any part of any Debt, or grant time or indulgence in respect
     thereof or enter into any agreement for any of the foregoing or do anything
     whereby the recovery of the whole or any part of any Debt may be impeded,
     delayed or prevented.

9.9  If the proceeds of any Debts are receivable or are received by the Bank or
     any nominee thereof (whether as a result of any notice of assignment having
     been given to the relevant debtor or obligor or otherwise) the Bank may
     deal with such Debts and their proceeds as it shall from time to time
     decide. In particular, but without limitation, it may pay the proceeds of
     any such Debts, or ensure that such proceeds are paid, into any of the
     Operating Accounts or, following the occurrence of an Enforcement Event,
     into any of the Controlled Accounts. If it does so, the provisions of
     clauses 9.5 to 9.8 (inclusive), insofar as they are relevant, shall apply
     to such proceeds to the same extent as if they had been so paid in by, or
     at the direction of, the Company.

          anything done on the Charged Property by the Company or any user or
          occupier;

                                       25

               thereof); and

          (2)  fully and punctually perform each of the Company's obligations in
               relation to each Permitted Encumbrance and, if the Bank so
               requests, immediately produce to the Bank evidence of such

               Company); and

     (G)  obtain valid VAT invoices in respect of all supplies made to the
          Company for VAT purposes and comply with all its obligations in

     Security:

     (A)  provide the Bank with such information in writing concerning the
          Company's business and affairs or all or any part of the Charged

          information and facilities which it may require and pay all expenses
          incurred by the Bank in connection therewith; and

     (C)  grant the Bank or its solicitors all reasonable facilities to enable
          it or them to carry out at the Company's expense such investigation of
          title to any part of the Charged Property and enquiries into matters

          or chargee.

9.13 The Company will notify the Bank in writing immediately upon each occasion
     that the Company becomes aware that:

     (A)  an Event of Default, or

     (B)  any other Enforcement Event, or

          Event,

     has occurred, and at the same time inform the Bank of any action taken or
     proposed to be taken in connection therewith.

<PAGE>

          (1)  accelerate or defer payment of any moneys due thereunder;

          (2)  waive, release, relax or vary any of the terms thereof;

11.  INSURANCES

11.1 The Company shall at all times during the subsistence of the Security:

     (A)  comply with all obligations with respect to insurance of or relating
          to any part of the Charged Property imposed by the terms of any
          contract between the Company and any person other than the Bank and at
          the request of the Bank produce evidence satisfactory to the Bank that
          such terms are being complied with;

     (B)  notwithstanding clause 11.1(A), and except to the extent that the Bank
          agrees otherwise in writing, insure and keep insured, with an insurer
          approved by the Bank, each part of the Charged Property as is of an
          insurable nature:

          (1)  against loss or damage by fire and by terrorist activity,

          (2)  against all other usual risks and contingencies which are insured
               against in accordance with sound commercial practice, and

          (3)  against all such other risks and contingencies which the Bank may
               specify at any time,

          for the amount of its full reinstatement or replacement cost, or in
          such other amount as the Bank may require with, if so required by the
          Bank, adequate provision also being made for architects' and other
          professional fees, the expense of demolition, site clearance and
          shoring-up, VAT and for three years (or such longer or shorter period
          as the Bank considers appropriate) loss of rent (taking into account
          potential increases as a result of rent reviews) and forward
          inflation; and

     (C)  except to the extent that the Bank permits otherwise by means of a
          prior written consent, also insure and keep itself and key persons in
          relation to its business insured, with an insurer approved by the
          Bank, against all other risks (including employer's liability, public
          liability, liability under the Defective Premises Act 1972 and all
          forms of consequential loss), and in such amounts, as the Bank may
          require at any time.

11.2 The Company will, at the request of the Bank made at any time, ensure that
     each Policy is on such of the following terms as the Bank requires:

                                       28

<PAGE>

     (A)  the Policy is in the joint names of the Company and the Bank (with the
          Bank noted as first loss payee) and such other name or names as the
          Bank may approve;

     (B)  the Policy is not capable of cancellation by the insurer (whether at
          the Company's request or otherwise) other than after giving 30 days'
          prior written notice to the Bank;

     (C)  the Policy provides that the insurer will notify the Bank promptly in
          writing if the premium or other moneys payable thereunder are not paid
          when due and will refrain from cancelling such Policy by reason only
          of the non-payment of such moneys for a period of at least 30 days
          from the date on which such notice is given;

     (D)  the Policy provides that the insurance effected shall not be
          invalidated or prejudiced so far as the Bank is concerned by any
          breach of the insuring conditions or any other act or omission unknown
          to or beyond the control of the Bank on the part of the Company or any
          other person;

     (E)  the Policy provides that the insurer will waive any rights of
          subrogation against the Bank or to any rights of the Bank against the
          Company;

     (F)  the Policy provides that the insurance is primary and without right of
          contribution from any other insurance policy (whether or not the Bank
          has any interest (including any interest as mortgagee, chargee or
          first loss payee) in such other policy);

     (G)  the Policy provides that the proceeds of the insurance are payable to
          the Bank; and

     (H)  such other terms as the Bank may specify from time to time.

11.3 The Company will, if so requested by the Bank, cause the interest of the
     Bank in each part of the Charged Property which is for the time being
     insured otherwise than in the Bank's own name or in joint names in
     accordance with clause 11.2(A) (or, as the case may be, each such part as
     may be specified by the Bank) to be noted by indorsement on the Policy or
     Policies relating thereto.

11.4 The Company will not effect any insurance policy if a claim thereunder
     would result in the operation of any average clause in that or any other
     insurance policy.

11.5 Except to the extent that the Bank permits otherwise by means of a prior
     written consent the Company will:

     (A)  do everything necessary (or which the Bank considers appropriate) to
          maintain each Policy in full force and effect and to ensure that no
          part of any Policy becomes void, voidable or unenforceable (including
          the punctual payment of all premiums before they become overdue); and

     (B)  forthwith (at the Company's cost) do all things necessary or which the
          Bank considers appropriate for restoring any part of any Policy which
          is or becomes void, voidable or unenforceable or to effect a new
          insurance policy to replace any part of any Policy which is or becomes
          void, voidable or unenforceable and to ensure that

                                       29

<PAGE>

          any such new insurance policy forms part of the Charged Property and
          is subject to this Debenture.

11.6 On the Bank's request the Company will immediately:

     (A)  deposit with the Bank each document relating to any insurance effected
          or maintained by the Company (whether or not effected or maintained in
          compliance with clause 11.1), including each Policy and each receipt
          or other evidence of payment of premiums and other amounts; and

     (B)  produce to the Bank any such insurance documents which have not been
          required to be deposited with the Bank and provide the Bank with
          copies of the same.

11.7 If the Company becomes aware that any Policy has been or is about to be
     cancelled or materially modified, the Company will immediately inform the
     Bank in writing and provide such details or evidence as the Bank may
     request.

11.8 The Company will procure that those parts of the Charged Property which are
     to be insured in accordance with this clause 11 are valued (at the
     Company's expense) annually or at such longer intervals as the Bank may
     agree in writing, in each case by competent professional valuers approved
     by the Bank, to determine their full reinstatement or replacement cost and
     will produce a copy of such valuation to the Bank within 14 days of it
     being received by the Company.

11.9 The Company shall reimburse the Bank on demand for all costs and expenses
     incurred by it in connection with any other review of the insurances in
     respect of the Charged Property or any part thereof which review may be
     conducted at any time and from time to time after the date hereof.

11.10 If the Company becomes aware of the occurrence of any event which may,
     ought to or would give rise to a claim under any Policy, the Company will
     immediately give written notice to the Bank of such event.

11.11 The Company will make or assist in the making of any appropriate claim
     under any Policy in such manner as the Bank may require. The Company will
     not, without the Bank's prior written consent, in any way admit, compromise
     or settle any claim or any liability or any matter which may be the subject
     of a claim under any Policy.

11.12 The Company authorises the Bank in the Company's name and on the Company's
     behalf to make any claim against the insurer under any part of any Policy
     and to admit, compromise or settle such claim and/or any liability relating
     to any such claim and/or any potential claim.

11.13 The Company also authorises the Bank to receive any amounts payable in
     respect of any Policy and/or any claim under any Policy and give a good
     discharge to the insurer in respect of such amounts.

11.14 The Company declares that it will hold all moneys received under any
     Policy relating to the Charged Property (whether or not it is one for the
     maintenance of which the Company is liable under this Debenture and whether
     the event by virtue of which such moneys became payable occurred before, on
     or after the date of this Debenture) on trust for the Bank to be applied:

                                       30

<PAGE>

     (A)  in or towards making good the loss in respect of which such moneys
          were received, or

     (B)  in accordance with clause 16.2,

     as the Bank may in its absolute discretion require except to the extent
     that a different application is required by law. Any such application
     required by the Bank (but not the creation of the trust) is subject to the
     rights of any person with a lawful claim upon such moneys, but in each case
     only insofar as the law requires the Bank to take account of those rights.

11.15 The Company hereby waives any right it may have to require that insurance
     proceeds be applied in reinstatement of any property or assets forming part
     of the Charged Property.

11.16 If default shall be made by the Company in complying with this clause 11,
     the Bank may, but shall not be required to, effect or renew any such
     insurance as is mentioned therein in such sum as the Bank shall think fit
     either in its own name or in the joint names of the Company and the Bank
     (with the Bank noted as first loss payee) and such other name or names as
     the Bank may approve or in the name of the Company with an indorsement of
     the Bank's interest. The Company shall reimburse all moneys expended by the
     Bank in so effecting or renewing any such insurance to the Bank on demand
     and shall pay interest thereon from the date of payment by the Bank until
     such sums are reimbursed at the rate and otherwise as mentioned in clause
     2.4.

12.  MONITORING THE SECURITY

12.1 The Company will permit the Bank to take any action which the Bank
     considers appropriate to ascertain whether or not the Company has fully
     complied with each of the Company's obligations under this Debenture and/or
     the extent to which the Charged Property remains an appropriate and/or
     adequate security for the Secured Liabilities. In particular:

     (A)  if the Bank so requests, the Company will immediately produce to the
          Bank such evidence in relation to those matters as the Bank reasonably
          considers appropriate; and

     (B)  the Company will permit the Bank to view, analyse and assess the state
          of repair and condition of any part of the Charged Property.

12.2 If at any time the Company fails, or is believed by the Bank to have
     failed, to perform or comply with any of its obligations under this
     Debenture, it shall be lawful for the Bank, but the Bank shall be under no
     obligation, to:

     (A)  enter all or any part of the Charged Property with agents appointed by
          it and architects, surveyors, contractors, workmen and others and to
          execute such works and do such other things as may in the opinion of
          the Bank be required to prevent, reduce the effect of or remedy such
          failure; and/or

     (B)  take such other steps on or in relation to the Charged Property
          (including the payment of money) as may in the opinion of the Bank be
          required for any of such purposes.

                                       31

<PAGE>

     The Company shall reimburse to the Bank on demand all sums expended by the
     Bank in executing such works, doing such things and taking such steps and
     shall pay interest thereon from the date of such demand until such sums are
     reimbursed at the rate and otherwise as mentioned in clause 2.4.

13.  EXTENSION AND VARIATION OF THE LAW OF PROPERTY ACT 1925

13.1 The restriction on the consolidation of mortgages imposed by Section 93(1)
     of the LPA shall not apply to this Debenture or the Security.

13.2 The powers of leasing, letting, entering into agreements for leases or
     lettings and accepting and agreeing to accept surrenders of leases
     conferred by Sections 99 and 100 of the LPA may be exercised by the Bank at
     any time on or after the occurrence of an Enforcement Event on such terms
     as the Bank shall in its absolute discretion think fit and without the need
     for the Bank to comply with any restrictions imposed by or any other
     provisions of the said Sections 99 and 100. The Bank may delegate the
     powers conferred by Sections 99 and 100 of the LPA, as varied and extended
     by this Debenture, to any person and any such delegation shall neither
     preclude the subsequent exercise of such powers by the Bank itself nor the
     subsequent delegation thereof to some other person or any revocation of
     such delegation.

13.3 Notwithstanding any other provisions of this Debenture, the Secured
     Liabilities shall be deemed for the purposes of Section 101 of the LPA to
     have become due and payable, and all the powers referred to in clause 14.1
     shall arise, on the date of this Debenture.

13.4 Sections 103 and 109(1) of the LPA shall not apply to the charges created
     by this Debenture. All the powers referred to in clause 14.1 may be
     exercised by the Bank without notice to the Company on or at any time after
     the occurrence of an Enforcement Event.

14.  ENFORCEMENT

14.1 On or at any time after the occurrence of an Enforcement Event the Bank
     may, without notice to the Company:

     (A)  take possession of and hold all or any part of the Charged Property;
          and/or

     (B)  appoint one or more persons to be:

          (1)  a receiver; and/or

          (2)  a receiver and manager; and/or

          (3)  (except to the extent that such appointment is or would be
               prohibited by section 72A of the Insolvency Act 1986) an
               administrative receiver,

          in each case, of the whole or any part of the Charged Property; and/or

     (C)  exercise in any manner it considers appropriate all or any of the
          powers, authorities and discretions:

          (1)  conferred on mortgagees by the LPA as varied or extended by this
               Debenture;

                                       32

<PAGE>

          (2)  conferred by this Debenture expressly or by implication on any
               Receiver; and

          (3)  otherwise conferred by statute or common law on mortgagees or
               receivers (including in the circumstances referred to by way of
               exception in clause 14.1(B), the appointment of an administrator
               under the Insolvency Act 1986).

14.2 The Bank may (subject to paragraph 17 of Schedule B1 to the Insolvency Act
     1986) exercise any of its powers under clauses 14.1(A) and 14.1(C) whether
     or not it shall have previously appointed any person to be a Receiver.

14.3 The Bank may:

     (A)  (so far as it is lawfully able) remove any Receiver; and

     (B)  appoint another person or other persons as Receiver or Receivers
          either in the place of a Receiver who has been so removed or who has
          ceased to act or to act jointly with any other Receiver.

14.4 The Bank's powers to appoint a person to be a Receiver shall:

     (A)  be in addition to, and not to the prejudice of, all statutory and
          other powers of appointment of the Bank to appoint a Receiver under
          the LPA as extended by this Debenture or otherwise;

     (B)  be and remain exercisable by the Bank in respect of any part of the
          Charged Property in respect of which no appointment of any person as a
          Receiver by the Bank shall from time to time be subsisting and
          notwithstanding that an appointment by the Bank shall have subsisted
          and been withdrawn in respect of any part of the Charged Property
          and/or shall be subsisting in respect of any other part of the Charged
          Property; and

     (C)  be without prejudice to any statutory power which the Bank may have to
          appoint an administrator of the Company under the Insolvency Act 1986
          or any other applicable enactment.

14.5 Every appointment of any person to be a Receiver and every removal of any
     Receiver may be made by deed or by instrument in writing under the hand of
     any officer or manager of the Bank or any person authorised for such
     purpose by the Bank or any such officer or manager.

14.6 If at any time two or more persons shall hold office as Receivers of the
     same part of the Charged Property, each such Receiver shall be entitled
     (unless the contrary shall be stated in the instrument appointing him) to
     exercise individually as well as jointly (and to the exclusion of the other
     or others of them) all the powers and discretions conferred on Receivers by
     this Debenture or by law.

14.7 Except (a) as provided by law, (b) for any liability of the Bank resulting
     from any appointment made by it in accordance with this clause and (c) for
     any liability of the Receiver resulting from any exercise by him of any
     powers on his own behalf in accordance with clause 15.2(Z)(3), each
     Receiver shall be deemed at all times and for all purposes to be the agent
     of the Company which shall be solely responsible for his acts, omissions,
     defaults, losses and misconduct, for all obligations and liabilities
     entered into, incurred or adopted by him and for the payment of his
     remuneration and the Bank will not

                                       33

<PAGE>

     be responsible, in any circumstances whatsoever, to the Company or to any
     other person for any of them. No Receiver shall at any time act as agent
     for the Bank unless the Bank shall expressly appoint the Receiver in
     writing to be its agent.

          other change in the Obligor or any other company, corporation,
          partnership or other person; or

     (G)  any other act or thing whatsoever which, but for this clause 20.5,
          would or might prejudice the Security or the right of the Bank to any
          such remedy except for a reassignment, release or discharge in
          accordance with the provisions of clause 21.

20.6 The Bank may choose when, where, how and how often to exercise each of its
     rights, powers and remedies as provided by this Debenture or by law. No
     failure on the part of the Bank to exercise, or any delay on its part in
     exercising, any such right, power or remedy shall impair the same or
     operate or be construed as a waiver thereof, nor shall any single, partial
     or defective exercise of any such right, power or remedy preclude any
     further or other exercise thereof or the exercise of any other such right,
     power or remedy. The rights and remedies provided in this Debenture are
     cumulative and not exclusive of any rights or remedies provided by law.

20.7 If, at any time, any provision of this Debenture is or becomes illegal,
     invalid or unenforceable in any respect (or any of the security intended to
     be created by or pursuant to this Debenture is ineffective) under any law
     of any jurisdiction, such illegality, invalidity, unenforceability or
     ineffectiveness shall not affect or impair:

     (A)  the legality, validity or enforceability of the remaining provisions
          or the effectiveness of any of the remaining security under such law;
          or

     (B)  the legality, validity or enforceability of such provision or the
          effectiveness of such security under the law of any other
          jurisdiction.

                                       42

20.8 Without prejudice to the generality of this Clause 20, the Company
     expressly confirms that it intends that the provisions of this Debenture
     and the sums covenanted to be paid and discharged by the Company pursuant
     to this Debenture shall extend from time to time to any variation,
     increase, extension or addition of or to the Finance Documents (however
     fundamental) and/or any facility or amount made available under the Finance
     Documents for the purposes of or in connection with any of the following:
     acquisitions of any nature; increasing working capital; enabling investor
     distributions to be made; carrying out restructurings; refinancing existing
     facilities; refinancing any other indebtedness; making facilities available
     to new persons; any other variation or extension of the purposes for which
     any such facility or amount might be made available from time to time; and
     any fees, costs and/or expenses associated with any of the foregoing.

21.  REDEMPTION OF SECURITY

21.1 Upon and subject to the Bank being satisfied that:

     (A)  it is under no commitment, obligation or liability (whether actual or
          contingent) to make advances or provide other financial accommodation
          to the Obligor under or pursuant to the Finance Documents or to any
          other person in respect of whose liabilities the Company has
          undertaken a liability to the Bank under or pursuant to the Finance
          Documents or which could otherwise lead to the Company incurring any
          further obligation to the Bank under or pursuant to the Finance
          Documents,

     (B)  the Company has no liability (whether actual or contingent) to the
          Bank under or pursuant to the Finance Documents in respect of any
          matter or thing whatsoever, and

     (C)  the Bank has no right, or does not intend to exercise any right, to
          retain the Security in accordance with clause 23.1,

     as soon as reasonably practicable thereafter and at the request and cost of
     the Company, the Bank shall (but subject to the rights and claims of any
     person having prior rights thereto) reassign the property and assets
     assigned to the Bank by or pursuant to this Debenture and release or
     otherwise discharge the Security but any such reassignment, release or
     discharge shall be subject to clause 22. Each such reassignment, release
     and discharge will be in such form as the Bank considers appropriate
     (including on a without recourse and a without warranty basis).

22.  AVOIDANCE OF PAYMENTS

22.1 Any settlement, reassignment, release or discharge between (a) the Company
     and (b) the Bank or any Receiver shall (whether or not so expressed) be
     deemed to be conditional upon no right, security, disposition or payment
     granted or made to the Bank or such Receiver (as the case may be) by the
     Company or any other person being void, avoided or set aside, either wholly
     or in part, for any reason whatsoever, including by virtue of any
     provisions or enactments relating to bankruptcy, insolvency, administration
     or liquidation for the time being in force.

22.2 In the event of the whole or any part of any such right, security,
     disposition or payment being so void, avoided or set aside, the Bank or
     such Receiver (as the case may be) shall be entitled to enforce this
     Debenture against the Company subsequently as if such settlement,
     reassignment, release or discharge had not occurred and such right,
     security,

                                       43

<PAGE>

     disposition or payment (or, as the case may be, the part thereof so void,
     avoided or set aside) had not been granted or made.

23.  RETENTION OF SECURITY

23.1 Notwithstanding any other provision of this Debenture or any settlement,
     reassignment, release, discharge or arrangement given or made by the Bank
     pursuant to a discharge in full of the Secured Liabilities, the Bank may
     retain the Security and all documents of title relating to, and
     certificates or other documents representing or evidencing ownership of,
     the Charged Property or any part thereof deposited with it pursuant to this
     Debenture until the later to occur of (a) the Bank being satisfied that the
     conditions set out in clauses 21.1(A) and 21.1(B) have been met and (b) the
     expiry of the Retention Period relating to such discharge or, if
     applicable, of the further period referred to in clause 23.2.

23.2 If at any time during the said Retention Period a petition shall be
     presented for an order for the winding-up of the Company or for the making
     of an administration order in respect of the Company or the Company shall
     commence to be wound-up voluntarily or any analogous proceedings shall be
     commenced in respect of the Company, the Bank may continue to retain the
     Security and the documents aforesaid for such further period as the Bank
     may determine and the Security and such documents shall be deemed to have
     continued to have been held as security for the Secured Liabilities.

23.3 As used in this clause 23, the expression "Retention Period" means, in
     relation to any discharge in full of the Secured Liabilities, the period
     beginning on the date on which that discharge was made and ending on the
     date falling one month after the expiration of the maximum period within
     which that discharge can be declared void, avoided or reduced by virtue of
     any applicable law or for any other reason whatsoever.

24.  SET-OFF

24.1 Without prejudice to any rights the Bank may have at law or in equity or
     otherwise, the Company authorises the Bank to apply any credit balance (in
     whatever currency denominated) to which the Company is now or may at any
     time hereafter become entitled on any account with any office or branch of
     the Bank in any jurisdiction in accordance with clause 16.2. The Bank may
     make such application at any time or times notwithstanding any specified
     maturity of any deposits standing to the credit of any such account. The
     Bank shall not be obliged to exercise any right given to it by this clause
     24.1 or to notify the Company before exercising any such right.

25.  NEW ACCOUNTS

25.1 If the Bank shall at any time receive or be deemed to have received notice
     of any Encumbrance affecting the whole or any part of the Charged Property
     which is prohibited by the terms of this Debenture:

     (A)  the Bank may open a new account or accounts for the Company in its
          books, and

     (B)  if the Bank does not in fact open any such new account, then unless it
          gives express written notice to the Company to the contrary, the Bank
          shall be treated as if it had in fact opened such account or accounts
          at the time when it received or was deemed to have received such
          notice,

                                       44

<PAGE>

     and as from such time and unless such express written notice shall be given
     to the Company, all payments by or on behalf of the Company to the Bank
     shall be credited or treated as having been credited to such new account or
     accounts and not as having been applied in reduction of the Secured
     Liabilities at such time.

26.  CURRENCY

26.1 Without prejudice to clause 26.4, the Bank may, in connection with any
     application of such moneys pursuant to clause 16.2 and whether for the
     purpose of or pending the discharge of any of the Secured Liabilities,
     convert any moneys referred to therein (including the proceeds of any
     previous conversion under this clause 26.1) from their existing currency of
     denomination into the currency of denomination (if different) of any of the
     Secured Liabilities.

26.2 Any such conversion from one currency to another shall be made at the
     Bank's then prevailing spot rate for the purchase of that other currency
     with the first-mentioned currency at the office of the Bank by which such
     conversion is made.

26.3 In the event that any such conversion is made for the purposes of the
     discharge of any of the Secured Liabilities in accordance with clause
     16.2(A), such Secured Liabilities shall only be discharged to the extent of
     the proceeds of such conversion actually received by the Bank (net of any
     premiums, commissions or other charges paid or incurred in connection
     therewith).

26.4 If for any reason any person receives in respect of any obligation of the
     Company under this Debenture or any order or judgment given or made in
     relation hereto an amount (the "received amount") in a currency other than
     the currency (the "contractual currency") in which such obligation is
     payable under this Debenture or such order or judgment, the received amount
     shall only constitute a discharge to the Company to the extent of the
     amount (the "converted amount") in the contractual currency which such
     person is able to purchase with the received amount at the prevailing
     market rate in the normal course of business as soon as reasonably possible
     after receipt. If the converted amount is less than the amount in the
     contractual currency due to such person under this Debenture or such order
     or judgment, the Company shall, as a separate and independent obligation,
     forthwith on demand:

     (A)  pay to such person an amount in the contractual currency equal to the
          deficit; and

     (B)  indemnify and keep indemnified such person from and against any
          liability, loss, cost or expense which such person may incur or suffer
          as a result of receiving the received amount or of converting it into
          the contractual currency.

27.  ASSIGNMENT

27.1 The Bank shall have a full and unfettered right to assign or transfer the
     whole or any part of the benefit of this Debenture.

27.2 The Company may not assign or transfer any of the Company's rights or
     obligations under this Debenture or enter into any transaction or
     arrangement which would result in any of those rights or obligations
     passing to or being held in trust for or for the benefit of another person.

                                       45

27.3 The Bank shall be entitled to disclose any information concerning the
     Company and any person connected or associated with it to:

     (A)  any person connected or associated with the Bank; and/or

     (B)  any actual or potential assignee or transferee of the whole or any
          part of the benefit of this Debenture and/or any other Finance
          Document; and/or

     (C)  any other successor or proposed successor of the Bank; and/or

     (D)  any person who has otherwise entered into or may otherwise enter into
          contractual relations with the Bank in relation to this Debenture
          and/or any other Finance Document.

     The Company represents and warrants that it has (and subject to any
     contrary requirement of law will maintain) any necessary authority by or on
     behalf of any person connected or associated with it to agree to the
     provisions of this clause.

27.4 The Company will, on the Bank's request, immediately execute and deliver to
     the Bank any form of instrument required by the Bank to confirm or
     facilitate any such assignment and/or transfer and/or contractual
     relations.

28.  COSTS AND EXPENSES

28.1 The Company shall on demand on a full indemnity basis pay to the Bank the
     amount of all costs and expenses (including any tax liability, legal costs
     and out-of-pocket expenses and, in each case, VAT or any similar tax
     charged or chargeable in respect thereof) incurred by the Bank in
     connection with:

     (A)  the preparation, negotiation, execution and delivery of this Debenture
          and the completion of the transactions contemplated herein,

     (B)  any stamping or registration of this Debenture or any judgment given
          in connection herewith,

          enforcement of any other security for or guarantee in respect of the
          Secured Liabilities,

     (D)  or as a consequence of taking or holding the Security or any claims or
          proceedings in relation thereto or to any of the Charged Property
          (including any proceedings instituted by or against the Bank in
          relation to the title to the whole or any part of the Charged
          Property),

     (E)  any actual or proposed amendment, supplement, waiver, consent,
          reassignment, release or discharge in relation to this Debenture, and

     (F)  any dealing with or obtaining advice about any matter or question
          arising out of or in connection with this Debenture,

     together with interest from the date of such demand until the date of
     payment by the Company at the rate and otherwise as mentioned in clause
     2.4.

<PAGE>

28.2 The Company shall pay all stamp, registration and other taxes to which this
     Debenture or any judgment given in connection herewith is or at any time
     may be subject (either directly or by reimbursing the Bank in accordance
     with clause 28.1(B)) and shall indemnify the Bank against any liabilities,
     costs, claims and expenses resulting from any failure to pay or delay in
     paying any such tax.

28.3 The cost of the Company complying with any of its obligations under this
     Debenture (including its obligations under clause 7) shall be borne by the
     Company.

29.  INDEMNITY

29.1 The Company agrees to indemnify and keep indemnified the Bank, each
     Receiver and each Appointee from and against all liabilities, losses, costs
     and expenses incurred or suffered by any such person in or in connection
     with or directly or indirectly as a result of:

     (A)  any of the obligations or undertakings expressed to be binding on or
          undertaken by the Company in or pursuant to this Debenture not being
          performed or observed fully and punctually, and/or

     (B)  any representation or warranty given or made by the Company in or
          pursuant to this Debenture being incorrect, untrue or misleading in
          any respect, and/or

     (C)  the exercise or purported exercise of any of the powers, authorities
          or discretions vested in any such person under or pursuant to this
          Debenture, and/or

     (D)  any matter or thing done or omitted by any such person in any way
          relating to the Charged Property or the Security,

     save where such liabilities, losses, costs and expenses arise as a result
     of the fraud, negligence or wilful misconduct of the person claiming to be
     so indemnified or any of its officers or employees.

30.  RESTRICTIONS ON LIABILITY

30.1 Except to the extent that any such exclusion will be prohibited or rendered
     invalid by law, the Bank will not in any circumstances whatsoever (whether
     by reason of taking possession of the Charged Property or any part thereof
     or for any other reason whatsoever and whether as a mortgagee in possession
     or on any other basis whatsoever):

     (A)  be liable to account to the Company or any other person as a mortgagee
          in possession;

     (B)  be liable to account to the Company or any other person for anything
          except the Bank's own actual receipts;

     (C)  be liable to the Company or any other person for any liabilities,

               relation to the Charged Property or any part thereof,

                                       47

<PAGE>

          except to the extent that they shall be caused by the fraud,

31.  PAYMENTS FREE OF DEDUCTION

31.1 All payments to be made by the Company under this Debenture shall be made
     in full without set-off or counter-claim and free and clear of and without
     deduction for or on account of tax unless the Company is required to make
     such payment subject to the deduction or withholding of tax, in which case
     the sum payable by the Company in respect of which such deduction or
     withholding is required to be made shall be increased to the extent
     necessary to ensure that, after the making of such deduction or
     withholding, the Bank or other recipient receives and retains (free from
     any liability in respect of any such deduction or withholding) a net sum
     equal to the sum which it or he would have received and so retained had no
     such deduction or withholding been made or required to be made. The Company
     shall:

     (A)  account in full for the amount so deducted or withheld to the relevant
          taxation or other competent authority on or before its due date; and

     (B)  furnish to the Bank or other recipient on or before such due date an
          official receipt of the relevant taxation or other competent authority
          for the amount so deducted or withheld or if such receipts are not
          issued by the authority concerned a certificate of deduction or
          equivalent evidence relating to such amount.

32.  VALUE ADDED TAX

32.1 All sums payable by the Company under or pursuant to this Debenture are
     exclusive of VAT. Accordingly, the Company shall pay such VAT in addition
     to any sum which would otherwise be due. Where the Company belongs to a
     different member state of the European Union from the payee for the
     purposes of the supply in respect of which the payment is made, the Company
     shall provide to the payee prior to the due date for payment or the raising
     of any invoice (whichever is the earlier) details of the Company's own VAT
     registration number.

33.  NOTICES

          deemed to have been given when 9.00 a.m. on a working day next occurs
          following such receipt; or

     (D)  sent by facsimile or telex, in which case, subject to confirmation of

          received by the sender at the start and end of the message (in the
          case of a telex), such notice shall be deemed to have been given upon
          the completion of its despatch, provided that if such completion takes
          place other than between 9.00 a.m. and 5.00 p.m. on a working day it
          shall (subject as aforesaid) be deemed to have been given when 9.00
