Dear Sirs,

UP TO US$100,000,000 REVOLVING CREDIT FACILITY AGREEMENT DATED 25TH OCTOBER,
1999

This letter is supplemental to and amends a credit agreement dated 25th October,
1999 and made between the Parent, the Original Borrowers, the Original
Guarantors, the Arranger, the Banks, the Facility Agent, the Security Agent and
the Overdraft Bank (the "CREDIT AGREEMENT") pursuant to the terms of which the
Banks have agreed to make Advances to the Borrowers up to an aggregate maximum
principal amount of US$100,000,000 on the terms set out therein.

We agree that the Credit Agreement shall be amended in accordance with the
provisions set out below.

Terms defined in the Credit Agreement shall bear the same meaning when used in
this letter unless otherwise defined herein or the context requires otherwise.

1.       AMENDMENTS

         amended as follows:

         (a)      for the avoidance of doubt, the parties listed on page 1 of
                  the Credit Agreement shall be amended to include "HSBC Bank
                  plc as overdraft bank (the "OVERDRAFT BANK")" at paragraph 8
                  and the definition of "Overdraft Bank" in Clause 1.1
                  (Definitions) shall be deleted.

         (b)      the following definition shall be included in Clause 1.1
                  (Definitions) as follows:

                  ""EXISTING OVERDRAFT FACILITY AGREEMENT" means the facility
                  letter dated 7th January, 1999 pursuant to which the Existing
                  Overdraft Facility was made available to, inter alios, Getty
                  U.K.."

         (c)      the definitions of "Finance Party" and "Finance Documents" in
                  Clause 1.1 (Definitions) shall be amended to read as follows:

                  ""FINANCE PARTY" means the Arranger, each Bank, the Facility
                  Agent and the Security Agent (together the "FINANCE PARTIES")
                  which term, for the purposes of
<PAGE>   2

                  Clauses 16 (Guarantee), 22 (The Agents and The Arranger) and
                  24.2 (Enforcement Costs) shall also include the Overdraft Bank
                  and any Hedging Bank."

                  Novation Certificates, the Borrower Accession Agreements, the

                  term for the purposes of the definition of "Security
                  Documents" (including all references to Finance Documents
                  wheresoever used in the Security Documents) and Clauses
                  1.2(iv) Constructions, 1.2(b) (Construction), 16 (Guarantee),

                  include the Existing Overdraft Facility Agreement and any
                  Hedging Document. For the avoidance of doubt, the Facility

                  Agreement or any Hedging Document a "Finance Document" in any
                  other context than as provided herein without the consent of

         (e)      two additional definitions shall be included in Clause 1.1

                  ""HEDGING BANK" means any Bank in its capacity as the provider
                  of hedging facilities for the hedging of exposures arising

                  ""HEDGING DOCUMENTS" means all currency swap, interest rate

                  Hedging Bank for the hedging of exposures arising pursuant to
                  the terms of this Agreement in each case as, and including,
                  any instrument pursuant to which the same are novated, varied,
                  supplemented or amended from time to time."

         (f)      Clause 1.2 (b) (Construction) shall be amended to read as
                  follows:

                  "(b)     Unless the contrary intention appears, a term used in
                           any other Finance Document or in any notice given
                           under or in connection with any Finance Document has
                           the same meaning in that Finance Document or notice
                           as in this Agreement."

         (g)      Clause 2.7 (Tranche B Commitment) shall be amended to read as
                  follows:

                  "2.7     TRANCHE A COMMITMENT

                  (a)      The Tranche A Commitment of HSBC Bank plc in its
                           capacity as a Bank as at the Signing Date will be
                           US$50,000,000 (unless it agrees in writing with the
                           Parent to increase its Tranche A Commitment up to a
                           specified amount).

<PAGE>   3

                  (b)      If and to the extent other banks or financial
                           institutions (each a "NEW BANK") are willing to
                           commit to participate in Tranche A following
                           syndication efforts by the Arranger then, upon any
                           Novation Certificate signed by a New Bank taking
                           effect in relation to Tranche A, the New Bank will be
                           treated as having taken a transfer from HSBC Bank plc
                           of the Tranche A Commitment specified in that
                           Novation Certificate as though HSBC Bank plc had
                           increased its Tranche A Commitment by the amount such
                           New Bank is willing to so commit immediately prior to
                           the Novation Certificate taking effect.

                  (c)      Commitment fee in respect of such undrawn part of the
                           Tranche A Commitment increased pursuant to this
                           Clause 2.7 will accrue under Clause 23.2 (Commitment
                           Fee) in relation to:

                           (i)      the  Tranche A  Commitment  of any New Bank,
                                    with  effect on and after the effective date
                                    of the relevant Novation Certificate; and

                           (ii)     any increased Tranche A Commitment which
                                    HSBC Bank plc agrees to as contemplated in
                                    paragraph (a) above, with effect on and
                                    after the date it agrees in writing to
                                    accept that increased Tranche A Commitment.

                  (d)      Nothing in this Clause 2.7 will oblige HSBC Bank plc
                           in its capacity as a Bank to make any Advance under
                           Tranche A which would result in the principal amount
                           outstanding under Tranche A being in excess of
                           US$50,000,000 at any time (except to the extent it
                           has agreed in writing to accept a Tranche A
                           Commitment in excess of such amount)."

         (h)      All  references  to  Tranche  B in the  Credit  Agreement
                  shall be deemed  deleted  in their entirety so that:

                  (i)      references to "Tranche B" in the definitions of
                           "Advance", "Commitment", "Facility", "Rollover
                           Advance" and "Total Commitments" in Clause 1.1
                           (Definitions) shall be deemed deleted; and

                  (ii)     the definitions of "Tranche B", "Tranche B
                           Commitment" in Clause 1.1 (Definitions) and Clauses
                           2.1(b) (Facilities), 3(b) (Purpose), 4.2 (Conditions

                           shall be deemed deleted in their entirety,

                  and all subsequent clauses and sub-clauses deemed renumbered
                  and cross referencing deemed amended accordingly.

         (i)      Clauses 4.1 (Conditions precedent to drawdown) will be amended
                  to read as follows:

                  "4.1     CONDITIONS PRECEDENT TO DRAWDOWN

                  (a)      Subject to the provisions of paragraph (b) below, the
                           obligations of each Finance Party to the Obligors
                           under this Agreement are subject to the

                           (Representations and Warranties) are correct as at
                           the Signing Date.

                  (b)      The Finance Parties shall not be obliged to
                           participate in any Tranche A Advance which would
                           result in the principal amount outstanding under
                           Tranche A being in excess of US$50,000,000 until the
                           date upon which the Facility Agent has (i) received
                           all of the documents set out in Part IA of Schedule 3

                  aggregate at that time of the Borrowings of the members of the

                  balances held by any member of the Group that are freely
                  convertible and transferable free of any encumbrances other
                  than Permitted Encumbrances in respect of Borrowings) all as
                  determined (subject only as may be required in order to
                  reflect the express inclusion or exclusion of items as
                  specified herein and/or in the definition of Borrowings in
                  Clause 1.1 (Definitions) in accordance with the Applicable
                  Accounting Principles and, where the calculation is being made
                  as at the end of any Accounting Period for which a Balance
                  Sheet of the Group has been or is required to be delivered to
                  the Facility Agent hereunder, determined from that Balance
                  Sheet."

         defined in the recitals to this Debenture have the same meaning when
         used in the remainder of this Debenture.

(b)      The provisions of Clause 1.2 of the Credit Agreement shall also apply
         hereto as if expressly set out herein (mutatis mutandis) with each
         reference to the Credit Agreement being deemed to be a reference to
         this Debenture.

(c)      The terms of the other Finance Documents and of any side letters
         between the parties hereto in relation to the Finance Documents are
         incorporated herein to the extent required for any purported

         Secured Lender under any Finance Document is likely to be capable of
         being avoided or otherwise set aside on the liquidation or
         administration of such Obligor or otherwise, then such amount shall not
         be considered to have been irrevocably paid for the purposes of this
         Debenture.

1.3      CERTIFICATES

         A certificate of the Security Agent setting forth the amount of any
         Secured Liability due from any Obligor shall be prima facie evidence of
         such amount against the Chargors and such Obligor in the absence of
         manifest error.

<PAGE>   5

2.       COVENANT TO PAY

2.1      COVENANT
         Each Chargor hereby, as primary obligor and not merely as surety,
         covenants with the Security Agent (as agent and trustee as aforesaid)
         that it will pay or discharge the Secured Liabilities on the due date
         therefor in the manner provided in the relevant Finance Document. Any
         amount not paid hereunder when due shall bear interest (as well after
         as before judgment and payable on demand) at the Default Rate from time
         to time from the due date until the date such amount is unconditionally
         and irrevocably paid and discharged in full, save to the extent that
         interest at such rate on such amount for such period is charged
         pursuant to the relevant Finance Document or any other Security
         Document.

2.2      RIGHT OF APPROPRIATION

         Upon the occurrence of an Event of Default and at any time thereafter
         while the same is continuing and not expressly waived by the Facility
         Agent the Security Agent (acting on the instructions of the Majority
         Banks save where the Security Agent reasonably considers that the delay
         which would be entailed in obtaining such instructions would materially
         prejudice the interests of the Secured Lender under the Finance
         Documents) shall be entitled to appropriate moneys and/or assets to
         Secured Liabilities in such manner or order as it sees fit (subject to
         Clause 15) and any such appropriation shall override any appropriation
         by any Obligor. This Clause 2.2 shall not, however, override the
         principle that (subject to Clause 15) the Secured Lenders are to share
         in recoveries on a pro rata basis.

3.       COVENANT TO MAKE FACILITIES AVAILABLE

         Each Secured Lender, by the Security Agent's execution of this
         Debenture, hereby covenants with each Obligor to the intent that each
         such covenant shall be binding on each Secured Lender severally in
         accordance with Clause 2.3 of the Credit Agreement (or the equivalent
         provision of any other Finance Document) (in each case as if the same
         applied to this Clause 3, mutatis mutandis) that each Secured Lender
         will, upon and subject to the terms of the Credit Agreement (or such
         other Finance Document), make the Facilities (or such other facilities
         as are provided for in such other Finance Document) available to the
         Borrowers and the other borrowers (party to such Finance Document) on
         and subject to the terms of such Finance Document (including, without
         limitation but subject as aforesaid, advances and further advances or
         other financial accommodation to the extent (if at all) that the making
         thereof by such Secured Lender is provided for in such Finance
         Document).

4.       FIXED CHARGES; ASSIGNMENTS

4.1      FIXED CHARGES

         Each Chargor as beneficial owner and with full title guarantee but
         subject to any Encumbrances permitted pursuant to Clause 19.6 of the
         Credit Agreement, as security for the payment, discharge and
         performance of all the Secured Liabilities at any time owed or due to
         the Secured Lenders (or any of them), charges in favour of the Security
         Agent (as agent and trustee for the Secured Lenders):

                  Schedule to the Deed of Accession by which it

<PAGE>   6

                  became party hereto (where relevant), together with all
                  buildings and Fixtures thereon, the proceeds of sale of all or
                  any part thereof and the benefit of any covenants for title
                  given or entered into by any predecessor in title and any
                  moneys paid or payable in respect of such covenants subject,
                  in the case of any leasehold properties, to any necessary
                  third party's consent to such mortgage being obtained;

         (b)      by way of first legal mortgage all estates or interests in any
                  freehold or leasehold property and any rights under any

                  a right to occupy or use property, (except any Security Assets
                  specified in paragraph (a) above) wheresoever situate now

                  the benefit of any covenants for title given or entered into
                  by any predecessor in title and any moneys paid or payable in
                  respect of such covenants subject, in the case of any
                  leasehold properties, to any necessary third party's consent
                  to such mortgage being obtained. For the avoidance of doubt on
                  such consent being obtained such leasehold property shall
                  automatically become subject to this charge and the relevant
                  Chargor shall promptly enter into a supplemental legal
                  mortgage in favour of the Security Agent, provide evidence as
                  to the power and authority to enter into such supplemental
                  legal mortgage and that it constitutes legally binding and
                  enforceable obligations of the relevant Chargor in each case
                  in such form as the Security Agent may reasonably require;

         (c)      by way of first fixed charge:

                  (i)      (to the extent that the same are not the subject of a

                           freehold or leasehold property and any rights under
                           any licence or other agreement or document which
                           gives any Chargor a right to occupy or use property,
                           wheresoever situate now or hereafter belonging to it
                           together with all buildings and Fixtures thereon, the
                           proceeds of sale of all or any part thereof and the
                           benefit of any covenants for title given or entered
                           into by any predecessor in title and any moneys paid
                           or payable in respect of such covenants, subject, in
                           the case of any leasehold properties, to any
                           necessary third party's consent to such charge being

                           such Chargor's stock in trade or work in progress;

                  (iii)    all moneys (including interest) from time to time
                           standing to the credit of each of its present and

                           provision of this Clause 4 (and in particular but
                           without limitation to sub-paragraph (iii) above) such
                           proceeds shall be released automatically from the
                           fixed charge effected by this sub-paragraph (v) upon
                           those proceeds being credited to any Security
                           Account;

                           other sub-paragraph of this paragraph (c) and are not
                           effectively assigned under Clause 4.3) all of its
                           rights and benefits under each of the Relevant

                           any necessary third party's consent to such charge
                           being obtained) any distributorship or agreement for
                           the licensing of Intellectual Property Rights or
                           similar agreements entered into by it and any letters
                           of credit issued in its favour;

                  (vii)    any beneficial interest, claim or entitlement of it
                           to any assets of any pension fund;

                           Schedule 5 and/or the Schedule to the Deed of
                           Accession by which it became party hereto (where
                           relevant)) owned by it, subject to any necessary (as
                           at the date of this Debenture) third party's consent
                           to such charge being obtained. To the extent that any
                           such Intellectual Property Rights are not capable of
                           being charged (whether by reason of lack of any such
                           consent as aforesaid or otherwise) the charge thereof
                           purported to be effected by this Clause 4.1(c)(xi)

                           damages, compensation, remuneration, profit, rent or
                           income which any Chargor may derive therefrom or be
                           awarded or entitled to in respect thereof, as
                           continuing security for the payment, discharge and
                           performance of the Secured Liabilities.

                  Provided that any property or assets situate in Scotland and
                  any property or assets the rights in and to which are governed
                  by the laws of Scotland shall be excluded from the mortgages
                  and charges created or effected by paragraphs (a) to (c)
                  inclusive above and provided further that the Excluded
                  Intellectual Property which are presently or may in the future

                  (a) to (c) inclusive above.

4.2      CHARGES ON SHARES

         Each Chargor, as beneficial owner and with full title guarantee, hereby
         as continuing security for the payment, discharge and performance of
         all the Secured Liabilities at any time owed or due to the Secured
         Lenders (or any of them):

         (a)      mortgages and charges and agrees to mortgage and charge to the
                  Security Agent (as agent and trustee for the Secured Lenders)
                  all Group Shares held now or in the future by it and/or any
                  nominee on its behalf, the same to be a security by way of a
                  first mortgage; and

         (b)      mortgages and charges and agrees to mortgage and charge to the
                  Security Agent (as agent and trustee for the Secured Lenders)
                  all the Related Rights accruing to all or any of the Group
                  Shares held now or in the future by it and/or any nominee on
                  its behalf, the same to be a security by way of a first
                  mortgage or charge.

                  PROVIDED THAT:

                  (i)      whilst no Event of Default exists, all dividends and
                           other distributions paid or payable as referred to in
                           paragraph (b) above may be paid directly to the
                           relevant Chargor (in which case the Security Agent or
                           its nominee shall execute any necessary dividend
                           mandate) and, if paid directly to the Security Agent,
                           shall be paid promptly by it to the relevant Chargor;
                           and

                  (ii)     subject to Clause 10.2, whilst no Event of Default
                           exists (including any Event of Default expressly
                           waived by the Facility Agent), all voting rights
                           attaching to the relevant Group Shares may be
                           exercised by the relevant Chargor or, where the
                           shares have been registered in the name of the
                           Security Agent or its nominee, as the relevant
                           Chargor may direct in writing, and the Security Agent
                           and any nominee of the Security Agent in whose name
                           such Group Shares are registered shall execute any
                           form of proxy or other document reasonably required
                           in order for the relevant Chargor to do so.

4.3      ASSIGNMENTS

(a)      Each Chargor as beneficial owner and with full title guarantee but
         subject to any Encumbrance permitted pursuant to the Credit Agreement,
         as continuing security for the payment, discharge and performance of
         all the Secured Liabilities at any time owed or due to the Secured
         Lenders (or any of them), hereby assigns and agrees to assign to the
         Security Agent (as agent and trustee for the Secured Lenders) all its
         right, title and interest (if any) in and to:

<PAGE>   9

         (i)      the Insurances;

         (ii)     the Acquisition Agreements;

         (iii)    the Hedging Documents; and

         (iv)     the Intra-Group Loan Documents.

(b)      Each Chargor shall forthwith give notice of each such assignment of its
         right, title and interest (if any):

         (i)      in and to the Insurances, by sending a notice in the form of
                  Part I of Schedule 3 (with such amendments as the Security
                  Agent may agree) duly completed to each of the other parties
                  to the Insurances; and

         (ii)     in and to the other Relevant Agreements, by sending a notice
                  substantially in the form of Part III of Schedule 3 (with such
                  amendments as the parties may agree) to each of the other
                  parties thereto,

         and the Company and each Chargor shall use its reasonable endeavours to
         procure that within 14 days of the date hereof each such other party
         delivers a letter of undertaking to the Security Agent in the form of
         Part II of Schedule 3 (in the case of the Insurances) or in the form of
         Part IV of Schedule 3 (in the case of each of the other Relevant
         Agreements), in each case with such amendments as the Security Agent
         may agree.

         This Debenture constitutes notice in writing to each Chargor of any
         charge or assignment of a debt owed by that Chargor to any other member
         of the Group contained in this Debenture.

(c)      To the extent that any such right, title and interest described in
         paragraphs (a) and (b) of this Clause 4.3 is not assignable or capable
         of assignment, the assignment thereof purported to be effected by
         paragraph (a) shall operate as:

         (i)      in the case of the Insurances, an assignment of any and all
                  proceeds of the Insurances received by each Chargor; and

         (ii)     in the case of the other Relevant Agreements, an assignment of
                  any and all damages, compensation, remuneration, profit, rent
                  or income which any Chargor may derive therefrom or be awarded
                  or entitled to in respect thereof,

         in each case as continuing security for the payment, discharge and
         performance of all the Secured Liabilities at any time owed or due to
         the Secured Lenders (or any of them).

(d)      Whilst no Event of Default exists (i) the Security Agent shall permit
         the relevant Chargor to exercise its rights (other than to receive
         payment of money) under any Relevant Agreement to which it is party,
         provided that the exercise of these rights in the manner proposed would
         not result in a Default under the terms of the Finance Documents and
         (ii) any payments received by the Security Agent under or in respect of
         the Relevant Agreements by virtue of this Debenture shall be paid by
         the Security Agent to the relevant Chargor save to the extent required
         by the terms of the Credit Agreement to be applied against any of the
         Secured Liabilities.

4.4      MISCELLANEOUS

(a)      The fact that no or incomplete details of properties are included or
         inserted in Schedule 2 or in the Schedule to the Deed of Accession (if
         any) by which any Chargor became party hereto shall not affect the
         validity or enforceability of the charges created by this Debenture
         (including, without limitation, the charges created by paragraphs (a),
         (b) and (c)(i) of Clause 4.1 and the charge created by Clause 5.1).

(b)      The omission from Schedule 5 or from the Schedule to the Deed of
         Accession (if any) by which any Chargor became party hereto of details
         of any Intellectual Property Rights owned or enjoyed by any Chargor
         shall not affect the validity or enforceability of the security created
         by this Debenture over such Intellectual Property Rights, provided, for
         the avoidance of doubt, that (save as created by Clause 5) no security
         is created by this Debenture over any Excluded Intellectual Property.

5.       FLOATING CHARGES

5.1      CREATION OF FLOATING CHARGES

         Each Chargor as beneficial owner and with full title guarantee subject
         to any Encumbrance permitted under the Credit Agreement, as security
         for the payment, discharge and performance of all the Secured
         Liabilities, charges in favour of the Security Agent (as agent and
         trustee for the Secured Lenders) by way of a first floating charge all
         its undertaking and assets whatsoever and wheresoever both present and
         future including, without limitation, any undertaking and assets
         situated in Scotland (whether or not the same may be mortgaged or
         charged by way of standard security)), subject always to all mortgages,
         fixed charges and assignments created by or pursuant to Clause 4 or any
         other provision of this Debenture.

5.2      RESTRICTIONS ON DEALING

         Each Chargor undertakes to each Secured Lender that, save as expressly
         permitted under the terms of this Debenture and the Credit Agreement,
         it will not:

         (a)      create or permit to subsist any Encumbrance over all or any of
                  its assets, rights or property other than pursuant to this
                  Debenture or any other Security Document; or

         (b)      part with, lease, sell, transfer, assign or otherwise dispose
                  of or agree to part with, lease, sell, transfer, assign or
                  otherwise dispose of all or any part of its assets, rights or
                  property or any interest therein,

         PROVIDED THAT if any Chargor gives notice to the Security Agent that
         such Chargor is required to dispose of or release any Excluded
         Intellectual Property Right, the Security Agent and each Secured Lender
         shall forthwith, at the cost of the Chargors, execute and do all such
         deeds, acts and things as may be necessary to release such Excluded
         Intellectual Property Right from the security constituted hereby,
         whether or not the security created hereby has become enforceable.

<PAGE>   11

5.3      CONVERSION OF FLOATING CHARGE

(a)      The Security Agent may by notice to any Chargor convert the floating
         charge hereby created into a specific charge as regards all or any of
         such Chargor's assets, rights and property (except to the extent that
         any such conversion is ineffective under Scots law in respect of any
         such assets, rights and property situated in Scotland and except in
         respect of the Excluded Intellectual Property) specified in the notice:

         (i)      if an Event of Default has occurred and is continuing and not
                  expressly waived by the Facility Agent; or

         (ii)     if the Security Agent in good faith considers such assets,
                  rights or property to be in reasonably forseeable danger of
                  being seized or sold under any form of distress, attachment,
                  execution or other legal process or to be otherwise in
                  jeopardy; or

         (iii)    if the Security Agent becomes aware or has reason to believe
                  that steps have been taken which would, in the reasonable
                  opinion of the Security Agent, be reasonably likely to lead to
                  the presentation of a petition to appoint an administrator in
                  relation to such Chargor (or such an administrator has been
                  appointed) or to wind up such Chargor or that any such
                  petition has been presented, which in the reasonable opinion
                  of the Security Agent is likely to result in the winding up of
                  such Chargor or the appointment of such an administrator; or

         (iv)     if such Chargor fails to comply, or takes or threatens to take
                  any action which in the reasonable opinion of the Security
                  Agent is likely to result in it failing to comply with its
                  obligations under Clause 5.2 of this Debenture.

(b)      The floating charge hereby created shall (in addition to the
         circumstances in which the same will occur under general law)
         automatically be converted into a fixed charge over the assets, rights
         and property of any Chargor (other than the Excluded Intellectual
         Property) on the convening of any meeting of the members of such
         Chargor to consider a resolution to wind such Chargor up (or not to
         wind such Chargor up) provided that this Clause 5.3(b) shall not apply
         to any Chargor's undertaking and assets situate in Scotland if, and to
         the extent that, a Receiver would not be capable of exercising his
         powers in Scotland pursuant to Section 72 of the Insolvency Act 1986 by
         reason of such automatic conversion.

(c)      The giving by the Security Agent of a notice pursuant to paragraph (a)
         above in relation to any class of any Chargor's assets, rights and
         property shall not be construed as a waiver or abandonment of the
         Security Agent's rights to give other similar notices in respect of any
         other class of assets or of any other of the rights of the Secured
         Lenders (or any of them) hereunder or under any of the other Finance
         Documents.

6.       CONTINUING SECURITY, ETC.

6.1      CONTINUING SECURITY

         The security constituted by this Debenture shall be continuing and will
         extend to the ultimate balance of all sums payable by the Obligors
         under the Finance Documents, regardless of any intermediate payment or
         discharge in whole or in part.

<PAGE>   12

6.2      BREAKING OF ACCOUNTS

         If for any reason the security constituted hereby ceases to be a
         continuing security in respect of any Obligor (other than by way of
         discharge of such security), the Secured Lenders (and each or any of
         them) may open a new account with or continue any existing account with
         such Obligor and the liability of each Chargor in respect of the
         Secured Liabilities relating to such Obligor at the date of such
         cessation shall remain regardless of any payments in or out of any such
         account.

6.3      REINSTATEMENT

(a)      Where any discharge (whether in respect of the obligations of any
         Obligor or any security for those obligations or otherwise) is made in
         whole or in part or any arrangement is made on the faith of any
         payment, security or other disposition which is avoided or must be
         restored on insolvency, liquidation or otherwise without limitation,
         the liability of each Chargor under this Debenture shall continue as if
         the discharge or arrangement had not occurred.

(b)      The Security Agent (acting reasonably) may (having taken appropriate
         legal advice) concede or compromise any claim that any payment,
         security or other disposition is liable to avoidance or restoration.

6.4      WAIVER OF DEFENCES

(a)      The liability of each Chargor hereunder will not be affected by any
         act, omission, circumstance, matter or thing which but for this
         provision would release or prejudice any of its obligations hereunder
         or prejudice or diminish such obligations in whole or in part,
         including without limitation and whether or not known to the Company,
         any other Chargor, any Secured Lender or any other person whatsoever:

         (i)      any time,  indulgence or waiver  granted to, or  composition
                  with,  any Obligor or any other person; or

         (ii)     the taking, variation, compromise, exchange, renewal or
                  release of, or refusal or neglect to perfect or take up or
                  enforce any rights or remedies against, or any security over
                  assets of, any Obligor or any other person or any
                  non-presentment or non-observance of any formality or other
                  requirement in respect of any instruments or any failure to
                  realise the full value of any other security; or

         (iii)    any legal limitation, disability, incapacity or lack of
                  powers, authority or legal personality of or dissolution or
                  change in the members or status of or other circumstance
                  relating to, any Obligor or any other person; or

         (iv)     any variation (however fundamental and whether or not
                  involving any increase in the liability of any Obligor
                  thereunder) or replacement of a Finance Document or the
                  Acquisition Agreements or any other document or security so
                  that references to that Finance Document or the Acquisition
                  Agreements or other documents or security in this Debenture
                  shall include each such variation or replacement; or

         (v)      any unenforceability, illegality, invalidity or frustration of
                  any obligation of any Obligor or any other person under any
                  Finance Document or the Acquisition Agreements or any other
                  document or security, or any failure of any other Obligor or

<PAGE>   13

                  proposed Obligor to become bound by the terms of any Finance
                  Document or the Acquisition Agreements, in each case whether
                  through any want of power or authority or otherwise; or

         (vi)     any postponement, discharge, reduction, non-provability or
                  other similar circumstance affecting any obligation of any
                  Obligor under a Finance Document or the Acquisition Agreements
                  resulting from any insolvency, liquidation or dissolution
                  proceedings or from any law, regulation or order,

         to the intent that each Chargor's obligations under this Debenture
         shall remain in full force, and this Debenture be construed
         accordingly, as if there were no such circumstance, act, variation,
         limitation, omission, unenforceability, illegality, matter or thing.

         No Secured Lender shall be concerned to see or investigate the powers
         or authorities of any of the Chargors or their respective officers or
         agents, and moneys obtained or Secured Liabilities incurred in
         purported exercise of such powers or authorities or by any person
         purporting to be an Obligor shall be deemed to form a part of the
         Secured Liabilities, and "Secured Liabilities" shall be construed
         accordingly.

(b)      For the avoidance of doubt, each Chargor shall be bound by this
         Debenture notwithstanding the fact that not all of the other members of
         the Group may have executed this Debenture and/or any of the other
         Security Documents required by the terms of the Finance Documents to be
         entered into by it or that any such document which has been entered
         into may be invalid, unenforceable or otherwise ineffective.

6.5      IMMEDIATE RECOURSE

         Each Chargor waives any right it may have of first requiring any
         Secured Lender to proceed against or enforce any other rights or
         security before enforcing the security constituted hereby.

6.6      APPROPRIATIONS

         Until all the Secured Liabilities have been unconditionally and
         irrevocably paid and discharged in full, each Secured Lender may:

         (a)      refrain from applying or enforcing any other moneys, security
                  or rights held or received by it in respect of the Secured
                  Liabilities or apply and enforce the same in such manner and
                  order as it sees fit (whether against the Secured Liabilities
                  or otherwise) and no Chargor shall be entitled to the benefit
                  of the same; and

         (b)      hold in a suspense account any moneys received from any
                  Obligor or on account of any Obligor's liability in respect of
                  the Secured Liabilities. Amounts standing to the credit of any
                  such suspense account shall bear interest at a rate considered
                  by such Secured Lender (acting reasonably) to be a fair market
                  rate.

6.7      NON-COMPETITION

         Until all the Secured Liabilities have been unconditionally and
         irrevocably paid and discharged in full no Chargor shall by virtue of
         any payment made, security realised or

<PAGE>   14

         moneys received or recovered under any of the Finance Documents for or
         on account of the liability of any other Obligor(s):

         (a)      be subrogated to any rights, security or moneys held, received
                  or receivable by any Secured Lender or be entitled to any
                  right of contribution or indemnity; or

         (b)      claim, rank, prove or vote as a creditor of any Obligor or its
                  estate in competition with any Secured Lender; or

         (c)      unless the Security Agent directs it to do so after an Event
                  of Default has occurred and is continuing, receive, claim or
                  have the benefit of any payment, distribution or security from
                  or on account of any Obligor, or exercise any right of set-off
                  as against any Obligor.

         Each Chargor will hold in trust for and forthwith pay or transfer to
         the Security Agent (acting as agent and trustee as aforesaid) any
         payment or distribution or benefit of security received by it contrary
         to the above. If any Chargor exercises any right of set-off contrary to
         the above, it will forthwith pay an amount equal to the amount set off
         to the Security Agent (acting as agent and trustee as aforesaid).

6.8      ADDITIONAL SECURITY

         This Debenture is in addition to and is not in any way prejudiced by
         any other security now or hereafter held by any Secured Lender.

6.9      SECURITY HELD BY CHARGOR

         No Chargor will without the prior written consent of the Security Agent
         hold any security from any other Obligor in respect of such Chargor's
         liability hereunder. Each Chargor will hold any security held by it in
         breach of this provision on trust for the Security Agent (as agent and
         trustee as aforesaid).

                  titles to the Mortgaged Property) have been properly performed
                  and observed and no Chargor has received notice of any
                  outstanding breach of covenant as regards the Mortgaged
                  Property which is reasonably likely to have a material adverse
                  effect on the value or saleability of, or any Chargor's right
                  to use, the Mortgaged Property;

                  (either generally or in the context of the present use of such
                  Mortgaged Property) or which conflicts with its present use or

                  by media located entirely on, in or under that Mortgaged
                  Property or by media elsewhere in respect of the use of which

                  imminent or likely material interruption of such passage or
                  provision, in each case where failure to be so connected or to
                  have such an easement would have a Material Adverse Effect
                  and/or would be reasonably likely to materially and adversely
                  affect the value, saleability or use of the Mortgaged
                  Property;

                  Adverse Effect and/or would be reasonably likely to materially
                  and adversely affect the value, saleability or use of the
                  Mortgaged Property;

         (ix)     nothing has arisen or been created or is subsisting which
                  would be an overriding interest over the Mortgaged Property

                  the Mortgaged Property enjoyed by the Secured Lenders or the

                  Mortgaged Property and/or the carrying on of the business at
                  the Mortgaged Property (including, without limitation, access
                  to and egress from the Mortgaged Property) the lack of which
                  would have a Material Adverse Effect and/or would be

                  person in respect of the ownership of the Mortgaged Property
                  or any interest therein which if adversely determined would

         (xii)    the Mortgaged Property is free from any tenancies or licences
                  to occupy, in each case which would have a Material Adverse

                  interests over the Security Shares and the Related Rights

                  parochial, local or of any other description) due and payable
                  by it within a reasonable time of the relevant due date in
                  accordance with the practice in the relevant jurisdiction and
                  prior to the accrual of any material fine or penalty or fine
                  for late payment (save to the extent that payment of the fine
                  is being contested in good faith and adequate reserves are
                  being maintained therefor) and save where non-payment will not
                  have a Material Adverse Effect;

         (e)      ACQUISITIONS AND LEGAL MORTGAGE notify the Security Agent in
                  writing forthwith upon the acquisition by such Chargor from
                  time to time of any freehold or leasehold property (including,
                  without limitation, by the exercise of such Chargor of any
                  option to acquire any freehold or leasehold property) or of
                  any agreement or option to acquire any freehold or leasehold
                  property or any licence or other right to occupy or use the
                  same and, on demand made to such Chargor by the Security Agent
                  and at the cost of such Chargor, execute and deliver to the
                  Security Agent a legal mortgage in favour of the Security
                  Agent (as agent and trustee as aforesaid) of any freehold and
                  leasehold properties which become vested in it after the date
                  hereof and all Fixtures thereon, the proceeds of sale of any
                  parts of these properties and the benefit of any covenants for
                  title given or entered into by a predecessor in title of the
                  Chargor and any moneys paid or payable in respect of those
                  covenants, to secure the payment or discharge of the Secured
                  Liabilities in such form (consistent with, and no more onerous
                  than, this Debenture) as the Security Agent may require. In
                  the case of any leasehold property in relation to which the
                  consent of the landlord in whom the reversion of that lease is
                  vested is required in order for such Chargor to perform any of
                  the foregoing obligations, such Chargor shall not be required
                  to perform that particular obligation unless and until it has
                  obtained the landlord's consent (which it shall use its
                  reasonable endeavours to do);

         (f)      USER use the Mortgaged Property only for such purpose or
                  purposes as may for the time being be authorised as the
                  permitted use or user thereof under or by virtue of the
                  Planning Acts and all title deeds relating to the Mortgaged
                  Property save where any failure to comply with this covenant
                  would not have a Material Adverse Effect;

         (g)      NOTICES within 14 days after the receipt by such Chargor of
                  any application, requirement, order or notice served or given
                  by any public or local or any other authority with respect to
                  the Security Assets (or any part thereof) which would have a
                  Material Adverse Effect, give written notice thereof to the
                  Security Agent and also (within seven days after demand)
                  produce the same or a copy thereof to the Security Agent and
                  inform it of the steps taken or proposed to be taken to comply
                  with, or dispute, any requirement thereby made or implicit
                  therein;

<PAGE>   20

         (h)      LEASES not without the previous consent in writing of the
                  Security Agent (not to be unreasonably withheld where the
                  Mortgaged Property is not required for its business) grant or
                  agree to grant (whether in exercise or independently of any
                  statutory power) any lease or tenancy of the Mortgaged
                  Property or any part thereof or accept a surrender of any
                  lease or tenancy or confer upon any person any contractual
                  licence or right to occupy the Mortgaged Property;

         (i)      H.M. LAND REGISTRY in respect of any freehold or leasehold
                  property which is hereafter acquired by such Chargor the title
                  to which is registered at H.M. Land Registry or the title to
                  which is required to be so registered, give such Registry
                  written notice of this Debenture and procure that notice of
                  these presents is duly noted in the Register to each such
                  title;

         (j)      DEPOSIT OF TITLE DEEDS deposit with (or arrange for the same
                  to be held by a person approved by the Security Agent to the
                  order of) the Security Agent all deeds and documents of title
                  relating to the Mortgaged Property and all Local Land Charges,
                  Land Charges and Land Registry Search Certificates and similar
                  documents received by or on behalf of such Chargor (and it is
                  hereby agreed that the Security Agent shall be entitled to
                  hold the same during the Security Period);

         (k)      ACCESS duly and punctually perform and observe all covenants
                  and stipulations restrictive or otherwise affecting all or any
                  part of the Mortgaged Property and all or any facilities
                  necessary for the enjoyment and use of the Mortgaged Property
                  and/or the carrying on of the business at the Mortgaged
                  Property, including without limitation access to and egress
                  from the Mortgaged Property, and indemnify the Security Agent
                  and each Secured Lender in respect of any breach thereof and
                  permit the Security Agent and any person nominated by it at
                  all reasonable times during normal business hours on
                  reasonable notice to enter upon the Mortgaged Property and
                  view the state of the same;

         (l)      INVESTIGATION OF TITLE grant the Security Agent or its lawyers
                  on request all such facilities within the power of such
                  Chargor to enable such lawyers (at the expense of such
                  Chargor) to carry out investigations of title to any property
                  (other than any of the Original Properties) which is or may be
                  subject to this security and enquiries into matters in
                  connection therewith as may be carried out by a prudent
                  mortgagee; and

         (m)      REPORT ON TITLE forthwith on demand by the Security Agent,
                  provide the Security Agent with a report as to the title of
                  such Chargor to any property which is or may be subject to
                  this security and related matters concerning the items which
                  may properly be sought to be covered by a prudent mortgagee in
                  a lawyer's report of this nature.

8.5      FURTHER NEGATIVE PLEDGE PROVISION

         If any Chargor creates or permits to subsist any Encumbrance in breach
         of the provisions of Clause 5.2(a) or Clause 8.3(a)(iv) of this
         Debenture or Clause 19.6 of the Credit Agreement, then, to the extent
         possible under applicable law, all the obligations of such Chargor
         under each of the Finance Documents shall automatically and immediately
         be secured upon the same assets equally and rateably with the other
         obligations secured thereon.

<PAGE>   21

8.6      CONSENTS

         Each Chargor will, and the Company will procure that each other Chargor
         will, promptly after the date hereof provide the Security Agent with a
         list of all those consents necessary to enable any of the property or
         assets of such Chargor to be fully and effectively charged pursuant to
         Clause 4.1 of this Debenture and/or the right, title and interest of
         any Chargor in any of the Relevant Agreements to be assigned to the
         Security Agent pursuant to Clause 4.3 of this Debenture. Each Chargor
         will, and will procure that each other Chargor will, forthwith use all
         reasonable endeavours to obtain any landlord's or other third party
         consents (and will provide copies of any such consents to the Security
         Agent) which are necessary to enable any of the property or assets of
         such Chargor to be fully and effectively charged pursuant to Clause 4.1
         of this Debenture or to enable any of the right, title and interest of
         any Chargor in any of the Relevant Agreements to be fully and
         effectively assigned to the Security Agent pursuant to Clause 4.3 of
         this Debenture.

9.       POWER TO REMEDY

         In case of default by any Chargor in repairing or keeping in repair or
         insuring the Mortgaged Property or any part thereof or in observing or
         performing any of the covenants or stipulations affecting the same as
         required by this Debenture, such Chargor will permit the Security Agent
         or its agents and contractors to enter on the Mortgaged Property and to
         comply with or object to any notice served on such Chargor in respect
         of the Mortgaged Property and to effect such repairs or insurance or
         generally do such things or pay all such costs, charges and expenses as
         the Security Agent may (acting reasonably) consider reasonably
         necessary or desirable to prevent or remedy any breach of covenant or
         stipulation or to comply with or object to any notice. Each Chargor
         will indemnify and keep the Security Agent indemnified against all
         losses, costs, charges and expenses reasonably incurred in connection
         with the exercise of the powers contained in this Clause 9.

10.      SPECIAL PROVISIONS RELATING TO THE SECURITY SHARES

10.1     REGISTRATION ON TRANSFER

         Each Chargor hereby authorises the Security Agent (at any time) to
         arrange for the Security Shares to be delivered to any nominee for the
         Security Agent or any purchaser or transferee (under the powers of
         realisation herein conferred) or registered as the Security Agent may
         (acting reasonably) feel appropriate to perfect the security thereover
         and to transfer or cause the Security Shares to be transferred to and
         registered in the name of any suitably qualified nominees of the
         Security Agent (as agent and trustee, as aforesaid) and each Chargor
         undertakes from time to time promptly to execute and sign all
         transfers, contract notes, powers of attorney and other documents (and
         promptly to register any such transfer of the Security Shares in the
         shareholders' register of the company in which the Security Shares are
         held) which the Security Agent may reasonably require for perfecting
         its title to any of the Security Shares or for vesting the same in
         itself or its nominee or in any purchasers or transferees (under the
         powers of realisation herein conferred).

10.2     POWERS

         The Security Agent and its nominee may at any time after an Event of
         Default has occurred and has not been expressly waived by the Facility
         Agent or in any other instance where the Security Agent is of the
         reasonable opinion that it is necessary for the avoidance of an Event

<PAGE>   22

         of Default or necessary for the protection of its material interests or
         the material interests of some or all of the Secured Lenders under any
         of the Finance Documents, exercise or refrain from exercising (in the
         name of each Chargor, the registered holder or otherwise and without
         any further consent or authority from any Chargor and irrespective of
         any direction given by any Chargor) in respect of the Security Shares
         any voting rights and any powers or rights under the terms thereof or
         otherwise which may be exercised by the person or persons in whose name
         or names the Security Shares are registered or who is the holder
         thereof, including, without limitation, all the powers given to
         trustees by Section 10(3) and (4) of the Trustee Act 1925 as amended by
         Section 9 of the Trustee Investments Act 1961 in respect of securities
         or property subject to a trust PROVIDED THAT in the absence of notice
         from the Security Agent each Chargor may and shall continue to exercise
         any and all voting rights with respect to the Group Shares subject
         always to the terms hereof. No Chargor shall without the previous
         consent in writing of the Security Agent exercise the voting rights
         attached to any of the Group Shares in favour of resolutions having the
         effect of changing the terms of the Group Shares (or any class of them)
         or any Related Rights or prejudicing the security hereunder or
         impairing the value of the Security Shares. Each Chargor hereby
         irrevocably appoints the Security Agent or its nominees its proxy to
         exercise all voting rights so long as the Group Shares remain
         registered in the names of the Chargors.

10.3     CALLS

         Each Chargor during the continuance of this security will make all
         payments which may become due in respect of any of the Security Shares
         and in the event of default in making any such payment the Security
         Agent may if it thinks fit make such payment on behalf of each Chargor.
         Any sums so paid by the Security Agent shall be repayable by the
         relevant Chargor to the Security Agent on demand together with interest
         at the Default Rate from the date of such payment by the Security
         Agent, and pending such repayment shall constitute part of the Secured
         Liabilities.

10.4     LIABILITY TO PERFORM

         It is expressly agreed that, notwithstanding anything to the contrary
         herein contained, each Chargor shall remain liable to observe and
         perform all of the conditions and obligations assumed by it in respect
         of the Security Shares and none of the Security Agent or the Secured
         Lenders shall be under any obligation or liability by reason of or
         arising out of the Share Mortgages. None of the Secured Lenders shall
         be required in any manner to perform or fulfil any obligation of any
         Chargor in respect of the Security Shares, or to make any payment, or
         to receive any enquiry as to the nature or sufficiency of any payment
         received by them, or to present or file any claim or take any other
         action to collect or enforce the payment of any amount to which they
         may have been or to which they may be entitled hereunder at any time or
         times.

10.5     ENFORCEMENT

         Upon the occurrence of an Event of Default and at any time thereafter
         while an Event of Default is continuing, the Security Agent shall be
         entitled to put into force and exercise immediately as and when it may
         see fit any and every power possessed by the Security Agent by virtue
         of the Share Mortgages or available to a secured creditor (so that
         Sections 93 and 103 of the Law of Property Act 1925 shall not apply to
         this security) and in particular (without limitation):

<PAGE>   23

         (i)      to sell all or any of the Security Shares in any manner
                  permitted by law upon such terms as the Security Agent shall
                  in its absolute discretion determine;

         (ii)     to collect, recover or compromise and give a good discharge
                  for any moneys payable to any Chargor in respect of the
                  Security Shares or in connection therewith; and

         (iii)    to act generally in relation to the Security Shares in such
                  manner as the Security Agent acting reasonably shall
                  determine.

         For the avoidance of doubt, each Chargor agrees that the enforceability
         of the Share Mortgages is not dependent on the performance or
         non-performance by any Secured Lender of its respective obligations
         under the Credit Agreement.

11.      THE ACCOUNT BANKS

11.1     IDENTITY

(a)      The Account Bank for each Chargor shall be HSBC Bank plc.

(b)      The Account Bank for any Chargor may be changed to any other bank or
         financial institution at any time with the agreement of the Company and
         the Security Agent but, in each case, such change shall only become
         effective upon the proposed new Account Bank agreeing with the Security
         Agent and the Company, in a manner reasonably satisfactory to the
         Security Agent, to fulfil the role of Account Bank hereunder.

11.2     NOTICE

(a)      The Parent on behalf of all the Chargors will forthwith give notice to
         the Account Bank for each Chargor (and forthwith on any change in the
         identity of the Account Bank for any Chargor give notice to the new
         Account Bank) of this Debenture in the form of Schedule 6 Part I and
         use its reasonable endeavours to procure that the Account Bank or new
         Account Bank (as the case may be) acknowledges such notice to the
         Security Agent in the form of Schedule 6 Part II (provided that, by its
         execution of this Debenture, each Chargor and HSBC Investment Bank plc
         shall be deemed to have given such notice or acknowledgement, as the
         case may be).

(b)      Promptly upon confirmation that the notice referred to in 11.2(a) above
         has been given, the Security Agent will deliver to the Account Bank a
         notice substantially in the form set out in Schedule 6 Part III. The
         Security Agent agrees that it will not send a further notice to the
         Account Bank of the type referred to in Schedule 6 Part III until this
         Debenture has become enforceable in accordance with Clause 10.5.

11.3     TRANSFER OF BALANCES

         The amount (if any) standing to the credit of the Security Accounts
         maintained with an old Account Bank shall be transferred to the
         corresponding Security Accounts maintained with a new Account Bank
         appointed pursuant to Clause 11.1 forthwith upon such appointment
         taking effect. Each Chargor hereby irrevocably gives all authorisations
         and instructions necessary for any such transfer to be made.

<PAGE>   24

11.4     FURTHER PERFECTION

         Each Chargor shall do all such things as the Security Agent may
         reasonably request in order to facilitate any change of Account Bank
         pursuant to Clause 11.1 or any transfer of credit balances pursuant to
         Clause 11.3 (including, without limitation, the execution of bank
         mandate forms) and the Security Agent is hereby irrevocably constituted
         the Company's and each other Chargor's attorney to do any such things
         should the Company or such other Chargor fail to do so.

12.      WHEN SECURITY BECOMES ENFORCEABLE

         The security constituted hereby shall become immediately enforceable
         upon the occurrence of an Event of Default and at any time thereafter
         whilst the same is continuing and the power of sale and other powers
         conferred by Section 101 of the Law of Property Act, 1925 as varied or
         amended by this Debenture shall be immediately exerciseable upon the
         occurrence of an Event of Default and at any time thereafter whilst the
         same is continuing. After the security constituted hereby has become
         enforceable, the Security Agent may in its absolute discretion enforce
         all or any part of such security in such manner as it sees fit or as
         the Majority Banks direct.

13.      ENFORCEMENT OF SECURITY

13.1     GENERAL

         For the purposes of all powers implied by statute the Secured
         Liabilities shall be deemed to have become due and payable on the date
         hereof and Section 103 of the Law of Property Act 1925 (restricting the
         power of sale) and Section 93 of the same Act (restricting the right of
         consolidation) shall not apply to this security. The statutory powers
         of leasing conferred on the Security Agent shall be extended so as to
         authorise the Security Agent to lease, make agreements for leases,
         accept surrenders of leases and grant options as the Security Agent
         shall think fit and without the need to comply with any of the
         provisions of sections 99 and 100 of the Law of Property Act 1925.

13.2     CONTINGENCIES

(a)      If the Security Agent enforces the security constituted by this
         Debenture in accordance with the terms of this Debenture (whether by
         the appointment of a Receiver or otherwise) at a time when no amounts
         are due under the Finance Documents (but at a time when amounts may
         become so due), the Security Agent (or such Receiver) may pay the
         proceeds of any recoveries effected by it into such number of interest
         bearing Realisations Accounts as it considers appropriate.

(b)      The Security Agent (or such Receiver) may (subject to the payment of
         any claims having priority to this security) withdraw amounts standing
         to the credit of the Realisations Accounts to:

         (i)      meet all costs, charges and expenses incurred and payments
                  made by the Security Agent (or such Receiver) in the course of
                  such enforcement;

         (ii)     pay remuneration to the Receiver as and when the same becomes
                  due and payable; and

<PAGE>   25

         (iii)    meet amounts due and payable under the Finance Documents as
                  and when the same become due and payable;

         in each case, together with interest thereon (as well after as before
         judgment and payable on demand) at the Default Rate from the date the
         same become due and payable until the date the same are unconditionally
         and irrevocably paid and discharged in full (provided that like
         interest payable under any of the Finance Documents should not be
         double counted).

(c)      No Chargor will be entitled to withdraw all or any moneys (including
         interest) standing to the credit of any Realisations Account until the
         expiry of the Security Period.

14.      RECEIVER

14.1     APPOINTMENT OF RECEIVER

(a)      At any time after this security becomes enforceable in accordance with
         Clause 12 or if any Chargor so requests the Security Agent in writing
         at any time, the Security Agent may without further notice appoint
         under seal or in writing under its hand any one or more qualified
         persons to be a Receiver of all or any part of the Security Assets in
         like manner in every respect as if the Security Agent had become
         entitled under the Law of Property Act 1925 to exercise the power of
         sale thereby conferred.

(b)      In this Clause "QUALIFIED PERSON" means a person who, under the
         Insolvency Act 1986, is qualified to act as a receiver of the property
         of any company with respect to which he is appointed or (as the case
         may require) an administrative receiver of any such company.

14.2     POWERS OF RECEIVER

(a)      Every Receiver appointed in accordance with Clause 14.1 shall have and
         be entitled to exercise all of the powers set out in paragraph (b)
         below in addition to those conferred by the Law of Property Act 1925 on
         any receiver appointed thereunder. A Receiver who is an administrative
         receiver of any Chargor shall have all the powers of an administrative
         receiver under the Insolvency Act 1986. If at any time there is more
         than one Receiver of all or any part of the Security Assets, each such
         Receiver may (unless otherwise stated in any document appointing him)
         exercise all of the powers conferred on a Receiver under this Debenture
         individually and to the exclusion of each other Receiver.

(b)      The powers referred to in the first sentence of paragraph (a) above
         are:

         (i)      TAKE POSSESSION to take immediate possession of, get in and
                  collect the Security Assets or any part thereof;

         (ii)     CARRY ON BUSINESS to carry on the business of such Chargor as
                  he may think fit;

         (iii)    PROTECTION OF ASSETS to make and effect all repairs and
                  insurances and do all other acts which such Chargor might do
                  in the ordinary conduct of its business as well for the
                  protection as for the improvement of the Security Assets and
                  to commence and/or complete any building operations on the
                  Mortgaged Property and to apply for and maintain any planning
                  permissions, building regulation approvals and any other

<PAGE>   26

                  permissions, consents or licences, in each case as he may in
                  his absolute discretion think fit;

         (iv)     EMPLOYEES to appoint and discharge managers, officers, agents,
                  accountants, servants, workmen and others for the purposes
                  hereof upon such terms as to remuneration or otherwise as he
                  may think proper and to discharge any such persons appointed
                  by any such Chargor;

         (v)      BORROW MONEY for the purpose of exercising any of the powers,
                  authorities and discretions conferred on him by or pursuant to
                  this Debenture and/or of defraying any costs, charges, losses
                  or expenses (including his remuneration) which shall be
                  incurred by him in the exercise thereof or for any other
                  purpose, to raise and borrow money either unsecured or on the
                  security of the Security Assets or any part thereof either in
                  priority to the security constituted by this Debenture or
                  otherwise and generally on such terms and conditions as he may
                  think fit and no person lending such money shall be concerned
                  to enquire as to the propriety or purpose of the exercise of
                  such power or to see to the application of any money so raised
                  or borrowed;

         (vi)     SELL ASSETS to sell, exchange, convert into money and realise
                  all or any part of the Security Assets (including, without
                  limitation, to sell any of the Mortgaged Property) by public
                  auction or private contract and generally in such manner and
                  on such terms as he shall think proper. Without prejudice to
                  the generality of the foregoing he may do any of these things
                  for a consideration consisting of cash, debentures or other
                  obligations, shares, stock or other valuable consideration and
                  any such consideration may be payable in a lump sum or by
                  instalments spread over such period as he may think fit.
                  Fixtures, other than landlords' fixtures, may be severed and
                  sold separately from the property containing them without the
                  consent of such Chargor;

         (vii)    LEASES to let all or any part of the Security Assets for such
                  term and at such rent (with or without a premium) as he may
                  think proper and to accept a surrender of any lease or tenancy
                  thereof on such terms as he may think fit (including the
                  payment of money to a lessee or tenant on a surrender);

         (viii)   COMPROMISE to settle, adjust, refer to arbitration, compromise
                  and arrange any claims, accounts, disputes, questions and
                  demands with or by any person who is or claims to be a
                  creditor of such Chargor or relating in any way to the
                  Security Assets or any part thereof;

         (ix)     LEGAL ACTIONS to bring, prosecute, enforce, defend and abandon
                  all such actions, suits and proceedings in relation to the
                  Security Assets or any part thereof as may seem to him to be
                  expedient;

         (x)      RECEIPTS to give valid receipts for all moneys and execute all
                  assurances and things which may be proper or desirable for
                  realising the Security Assets;

         (xi)     SUBSIDIARIES to form a subsidiary or subsidiaries of such
                  Chargor and transfer to any such subsidiary all or any part of
                  the Security Assets; and

<PAGE>   27

         (xii)    GENERAL POWERS to do all such other acts and things as he may
                  consider desirable or necessary for realising the Security
                  Assets or any part thereof or incidental or conducive to any
                  of the matters, powers or authorities conferred on a Receiver
                  under or by virtue of this Debenture, to exercise in relation
                  to the Security Assets or any part thereof all such powers,
                  authorities and things as he would be capable of exercising if
                  he were the absolute beneficial owner of the same and to use
                  the name of such Chargor for all or any of such purposes.

14.3     REMOVAL AND REMUNERATION

         The Security Agent may from time to time by writing under its hand
         (subject to any requirement for an order of the court in the case of an
         administrative receiver) remove any Receiver appointed by it and may,
         whenever it may deem it expedient, appoint a new Receiver in the place
         of any Receiver whose appointment may for any reason have terminated
         and may from time to time fix the remuneration of any Receiver
         appointed by it.

14.4     SECURITY AGENT MAY EXERCISE

         To the fullest extent permitted by law, all or any of the powers,
         authorities and discretions which are conferred by this Debenture
         (either expressly or impliedly) upon a Receiver of the Security Assets
         may be exercised after the security hereby created becomes enforceable
         in accordance with Clause 12 by the Security Agent in relation to the
         whole of such Security Assets or any part thereof without first
         appointing a Receiver of such property or any part thereof or
         notwithstanding the appointment of a Receiver of such property or any
         part thereof.

15.      APPLICATION OF PROCEEDS

         Any moneys received by the Security Agent or by any Receiver appointed
         by it pursuant to this Debenture and/or under the powers hereby
         conferred shall, after the security hereby constituted shall have
         become enforceable in accordance with Clause 12 but subject to the
         payment of any claims having priority to this security and to the
         Security Agent's and such Receiver's rights under Clauses 13.2 and
         14.2, be applied by the Security Agent for the following purposes and,
         unless otherwise determined by the Security Agent or such Receiver, in
         the following order or priority (but without prejudice to the right of
         the Security Agent or any Secured Lender to recover any shortfall from
         any Chargor):

         (a)      in satisfaction of or provision for all costs, charges and
                  expenses incurred and payments made by the Security Agent or
                  any Receiver appointed hereunder and of all remuneration due
                  hereunder together with interest on the foregoing (as well
                  after as before judgment and payable on demand) at the Default
                  Rate from time to time from the date the same become due and
                  payable until the date the same are unconditionally and
                  irrevocably paid and discharged in full;

         (b)      in or towards payment of the Secured Liabilities or such part
                  of them as is then due and payable; and

         (c)      in payment of the surplus (if any) to any Chargor or other
                  person entitled thereto.

<PAGE>   28

16.      NO LIABILITY AS MORTGAGEE IN POSSESSION

         The Security Agent shall not nor shall any Receiver appointed as
         aforesaid by reason of it or the Receiver entering into possession of
         the Security Assets or any part thereof be liable to account as
         mortgagee in possession or be liable for any loss on realisation or for
         any default or omission for which a mortgagee in possession might be
         liable. Every Receiver duly appointed by the Security Agent under the
         powers in that behalf herein contained shall be deemed to be the agent
         of the relevant Chargor for all purposes and shall as such agent for
         all purposes be deemed to be in the same position as a Receiver duly
         appointed by a mortgagee under the Law of Property Act 1925. The
         relevant Chargor alone shall be responsible for his contracts,
         engagements, acts, omissions, defaults and losses and for liabilities
         incurred by him and neither the Security Agent nor any Secured Lender
         shall incur any liability therefor (whether to the Company, any other
         Chargor or to any other person whatsoever) by reason of the Security
         Agent's making his appointment as such Receiver other than in the case
         of wilful neglect or negligence on the part of a Receiver or the
         Security Agent. Every such Receiver and the Security Agent shall be
         entitled to all the rights, powers, privileges and immunities by the
         Law of Property Act 1925 conferred on mortgagees and receivers when
         such receivers have been duly appointed under the said Act but so that
         Section 103 of the Law of Property Act 1925 shall not apply.

17.      PROTECTION OF THIRD PARTIES

         No purchaser, mortgagee or other person or company dealing with the
         Security Agent or the Receiver or its or his agents shall be concerned
         to enquire whether the Secured Liabilities have become payable or
         whether any power which the Receiver is purporting to exercise has
         become exercisable or whether any money remains due under this
         Debenture or the Finance Documents or to see to the application of any
         money paid to the Security Agent or to such Receiver.

18.      TAXES

         All payments by any Chargor under this Debenture to or for the account
         of any Secured Lender shall be made without any set off, counterclaim,
         withholding or other deductions and free and clear of and without
         deduction or withholding for or on account of any Taxes (subject to the
         exceptions in Clause 11 of the Credit Agreement). If any Tax or amounts
         in respect of Tax must be deducted, or any other deductions must be
         made, from any amounts payable or paid by such Chargor, or paid or
         payable by the Security Agent to another Secured Lender, under this
         Debenture, or any such payment shall otherwise be required to be made
         subject to any Tax, such Chargor shall pay such additional amounts as
         may be necessary to ensure that the relevant Secured Lender receives a
         net amount equal to the full amount which it would have received had
         payment not been made subject to Tax.

19.      EXPENSES

19.1     UNDERTAKING TO PAY

         All reasonable costs, charges and expenses incurred and all payments
         made by the Security Agent or any Receiver appointed hereunder in the
         lawful exercise of the powers hereby conferred whether or not
         occasioned by any act, neglect or default of any Chargor shall carry
         interest (as well after as before judgment) at the Default Rate from
         time to time from the later of the date the same are incurred or become
         payable until the date the same are

<PAGE>   29

         unconditionally and irrevocably paid and discharged in full. The amount
         of all such costs, charges, expenses and payments and all such interest
         thereon and all remuneration payable hereunder shall be payable by the
         Chargors on demand. All such costs, charges, expenses and payments
         shall be paid and charged as between the Security Agent and the
         Chargors or any of them on the basis of a full indemnity and not on the
         basis of party and party or any other kind of taxation.

19.2     INDEMNITY

         The Secured Lenders and every Receiver, attorney, manager, agent or
         other person appointed by the Security Agent hereunder shall be
         entitled to be indemnified out of the Security Assets in respect of all
         liabilities and expenses properly incurred by them in the execution or
         purported execution of any of the powers, authorities or discretions
         vested in them pursuant hereto and against all actions, proceedings,
         costs, claims and demands in respect of any matter or thing done or
         omitted in any way relating to the Security Assets and the Secured
         Lenders and any such Receiver may retain and pay all sums in respect of
         the same out of any moneys received under the powers hereby conferred.
         Notwithstanding the foregoing no Secured Lender or Receiver and no
         person appointed by the Security Agent as aforesaid shall be entitled
         to be indemnified in respect of any part of the foregoing which results
         from such party's negligence or wilful misconduct.

20.      DELEGATION BY SECURITY AGENT

         The Security Agent or any Receiver appointed hereunder may at any time
         and from time to time delegate by power of attorney or in any other
         manner to any properly qualified person or persons all or any of the
         powers, authorities and discretions which are for the time being
         exercisable by the Security Agent or such Receiver under this Debenture
         in relation to the Security Assets or any part thereof. Any such
         delegation may be made upon such terms (including power to
         sub-delegate) and subject to such regulations as the Security Agent or
         such Receiver may think fit.

21.      FURTHER ASSURANCES

21.1     GENERAL

         Each Chargor shall at its own expense execute and do all such
         assurances, acts and things as the Security Agent may reasonably
         require for perfecting or protecting the security intended to be
         created hereby over the Security Assets or any part thereof or for
         facilitating (if and when this security becomes enforceable) the
         realisation of the Security Assets or any part thereof and in the
         exercise of all powers, authorities and discretions vested in the
         Security Agent or any Receiver of the Security Assets or any part
         thereof or in any such delegate or sub-delegate as aforesaid. To that
         intent, each Chargor shall in particular execute all transfers,
         conveyances, assignments and releases of such property whether to the
         Security Agent or to its nominees and give all notices, orders and
         directions and make all registrations which the Security Agent may
         reasonably think expedient.

21.2     LEGAL CHARGE

         Without prejudice to the generality of Clause 21.1, each Chargor will
         forthwith at the request of the Security Agent execute a legal
         mortgage, charge or assignment over all or any of the Security Assets
         subject to or intended to be subject to any fixed security hereby
         created in

<PAGE>   30

         favour of the Security Agent (as agent and trustee as aforesaid) in
         such form as the Security Agent may reasonably require but containing
         terms no more onerous than those in this Debenture.

21.3     FURTHER SUBSIDIARIES

(a)      Each Chargor hereby undertakes to ensure that each company which
         becomes a Subsidiary (whether direct or indirect) of any Chargor after
         the date hereof shall, forthwith upon being required to grant security
         pursuant to Clause 17.3(a) of the Credit Agreement, execute a Deed of
         Accession substantially in the form set out in Schedule 7 and such
         company shall on the date on which such Deed of Accession is executed
         by it become a party to this Debenture in the capacity of a Chargor and
         this Debenture shall be read and construed for all purposes as if such
         company had been an original party hereto as a Chargor (but for the
         avoidance of doubt the security created by such company shall be
         created on the date of the Deed of Accession). The Security Agent is
         authorised to agree any amendments or change to the form or manner in
         which any such member of the Group gives such a guarantee and security
         (including acceptance of a limit on the liability of such member of the
         Group) which is in the reasonable opinion of the Security Agent
         necessary in order that such guarantee or security may lawfully be
         given.

(b)      The Company shall procure that all registrations or other steps
         necessary to perfect or protect any security created pursuant to any
         Deed of Accession is completed as soon as practicable after the date
         thereof and in any event within any applicable time limit.

22.      REDEMPTION OF PRIOR MORTGAGES

         The Security Agent may, at any time after the security hereby
         constituted has become enforceable, redeem any prior Encumbrance over
         or against the Security Assets or any part thereof or procure the
         transfer thereof to itself and may settle and pass the accounts of the
         prior mortgagee, chargee or encumbrancer. Any accounts so settled and
         passed shall be conclusive and binding on each Chargor. All principal
         moneys, interest, costs, charges and expenses of and incidental to such
         redemption and transfer shall be paid by the Chargors to the Security
         Agent on demand.

23.      POWER OF ATTORNEY

23.1     APPOINTMENT

         Each Chargor hereby by way of security and in order more fully to
         secure the performance of its obligations hereunder irrevocably
         appoints the Security Agent and every Receiver of the Security Assets
         or any part thereof appointed hereunder and every such delegate or
         sub-delegate as aforesaid to be its attorney acting severally, and on
         its behalf and in its name or otherwise, after the occurrence of an
         Event of Default which is continuing and has not been expressly waived
         by the Facility Agent, to execute and do all such assurances, acts and
         things which such Chargor is required to do and fails to do under the
         covenants and provisions contained in this Debenture (including,
         without limitation, to make any demand upon or to give any notice or
         receipt to any person owing moneys to such Chargor and to execute and
         deliver any charges, legal mortgages, assignments or other security and
         any transfers of securities) and generally in its name and on its
         behalf to exercise all or any of the powers, authorities and
         discretions conferred by or pursuant to this Debenture or by statute on
         the Security Agent or any such Receiver, delegate or sub-delegate and
         (without prejudice to the

<PAGE>   31

         generality of the foregoing) to seal and deliver and otherwise perfect
         any deed, assurance, agreement, instrument or act which it or he may
         reasonably deem proper in or for the purpose of exercising any of such
         powers, authorities and discretions.

23.2     RATIFICATION

         Each Chargor hereby ratifies and confirms and agrees to ratify and
         confirm whatever any such attorney as is mentioned in Clause 23.1 shall
         do or purport to do in the exercise or purported exercise of all or any
         of the powers, authorities and discretions referred to in such Clause.

24.      NEW ACCOUNTS

         If the Security Agent or any Secured Lender receives or is deemed to be
         affected by notice whether actual or constructive of any subsequent
         charge or other interest affecting any part of the Security Assets
         and/or the proceeds of sale thereof, the Security Agent or such Secured
         Lender (as the case may be) may open a new account or accounts with any
         Obligor. If the Security Agent or such Secured Lender (as the case may
         be) does not open a new account it shall nevertheless be treated as if
         it had done so at the time when it received or was deemed to have
         received notice and as from that time all payments made to the Security
         Agent or such Secured Lender (as the case may be) shall be credited or
         be treated as having been credited to the new account and shall not
         operate to reduce the amount for which this Debenture is security.

25.      STAMP TAXES

         Each Chargor shall pay and, forthwith on demand, indemnify the Security
         Agent and each Secured Lender against any liability it incurs in
         respect of any stamp, registration and similar Tax which is or becomes
         payable in connection with the entry into, performance or enforcement
         of this Debenture.

26.      ASSIGNMENTS, ETC.

26.1     THE SECURITY AGENT

         The Security Agent may assign and transfer all of its respective rights
         and obligations hereunder to a replacement Security Agent appointed in
         accordance with the terms of the Credit Agreement. Upon such assignment
         and transfer taking effect, the replacement Security Agent shall be and
         be deemed to be acting as agent and trustee for each of the Secured

                  law; and

         (iii)    may be waived only in writing and specifically.

         Chargor's obligations hereunder if so instructed by the Majority Banks.

28.      SET-OFF

28.1     GENERAL

         The Security Agent and each Secured Lender, after the occurrence of an
         Event of Default which is continuing and has not been expressly waived
         by the Facility Agent, may (but shall not be obliged to) set off any
         obligation which is due and payable by any Chargor and unpaid (whether
         under the Finance Documents or which has been assigned to the Security
         Agent by any other Chargor hereunder) against any obligation (whether
         or not matured) owed by the Security Agent or such Secured Lender (as
         the case may be) to such Chargor, regardless of the place of payment,
         booking branch or currency of either obligation. If the obligations are
         in different currencies, the Security Agent or such Secured Lender (as
         the case may be) may convert either obligation at a market rate of
         exchange in its usual course of business for the purpose of the
         set-off.

         Without prejudice to Clause 28.1, if any time deposit matures on any

         (i)      this security has become enforceable; and

         (ii)     no amount of the Secured Liabilities is due and payable,

         such time deposit shall automatically be renewed for such further
         maturity as the Security Agent or such Secured Lender in its absolute
         discretion considers appropriate unless the Security Agent or such
         Secured Lender otherwise agrees in writing.

                            FORM OF DEED OF ACCESSION

THIS DEED OF ACCESSION dated [           ], 199[  ] is made BETWEEN:

(1)      [             ]  (the "NEW  CHARGOR"),  a company  incorporated  in
         England  or Wales whose registered office is at
         [             ];

(2)      GETTY  COMMUNICATIONS  LIMITED  (the  "COMPANY")  for itself and as
         agent for and on behalf of each of the other Chargors named in the
         Debenture referred to below; and

(3)      HSBC INVESTMENT BANK PLC as the Security Agent.

WHEREAS

(A) The New Chargor is or will on the date hereof become a wholly-owned
Subsidiary of the Company.

(B)      The Company has entered into a debenture dated [ ], 1999 (as
         supplemented and amended by Deeds of Accession or otherwise from time
         to time, the "DEBENTURE") between the Company, each of the companies
         named therein as Chargors, and HSBC Investment Bank plc as agent and
         trustee for certain Secured Lenders as identified therein.

(C)      The New Chargor at the request of the Company and in consideration of
         the Secured Lenders making or continuing to make facilities available
         to the Company or any other member of the Group and after giving due
         consideration to the terms and conditions of the Finance Documents and
         the Debenture and satisfying itself that there are reasonable grounds
         for believing that the entry into this Deed by it will be of benefit to
         it, has decided in good faith and for the purpose of carrying on its
         business to enter into this Deed and thereby become a Chargor under the
         Debenture.

NOW THIS DEED WITNESSES as follows:

1.       Terms defined in the Debenture shall have the same meaning in this
         Deed.

2.       The New Chargor hereby agrees:

         (a)      to become a party to and to be bound by the terms of the
                  Debenture as a Chargor with immediate effect and so that the
                  Debenture shall be read and construed for all purposes as if
                  such New Chargor had been an original party thereto in the
                  capacity of Chargor (but so that the security created
                  consequent on such accession shall be created on the date
                  hereof); and

         (b)      to be bound by all the covenants and agreements in the
                  Debenture which are expressed to be binding on a Chargor.

3.       (a)      In accordance with the foregoing, the New Chargor as
                  beneficial owner and with full title guarantee subject to the
                  Encumbrances permitted pursuant to the Credit

<PAGE>   55

                  Agreement now grants to the Security Agent as agent and
                  trustee for the Secured Lenders the assignments, charges,
                  mortgages and other security described in the Debenture as
                  being granted, created or made by Chargors thereunder in
                  favour of the Security Agent as agent and trustee for the
                  Secured Lenders and grants to the Security Agent as agent and
                  trustee for the Secured Lenders the floating charge as
                  described in Clause 5.1 of the Debenture, to the intent that
                  its assignments, charges, mortgages and other security shall
                  be effective and binding upon it and its property and assets
                  and shall not in any way be avoided, discharged or released or
                  otherwise adversely affected by any ineffectiveness or
                  invalidity of the Debenture or of any other party's execution
                  thereof or any other Deed of Accession, or by any avoidance,
                  invalidity, discharge or release of any assignment, charge or
                  mortgage contained in the Debenture or in any other Deed of
                  Accession.

         (b)      Without limiting the generality of the other provisions of
                  this Deed and the Debenture, pursuant to the terms hereof and
                  of the Debenture, the New Chargor as beneficial owner and with
                  full title guarantee subject to any Encumbrance permitted
                  pursuant to the Credit Agreement, as security for the payment,
                  discharge and performance of all Secured Liabilities, hereby
                  and by the Debenture in favour of the Security Agent (as agent
                  and trustee for itself and each of the Secured Lenders):

                  (i)      charges by way of first legal mortgage all the
                           property (if any) now belonging to it brief

                           the Debenture and/or the Schedule to this Deed;

                  (ii)     subject to any necessary third party consents being
                           obtained, assigns and agrees to assign all of its
                           right, title and interest (if any) in and to each of
                           the contracts and agreements specified in Clause
                           4.3(a) of the Debenture and/or the Schedule to this
                           Deed; and

                  (iii)    agrees that the New Chargor's estates and other
                           interests in certain specific Intellectual Property
                           Rights for the purposes of Clause 4.1(c)(xi) of the

                           of Clause 4.2 thereof, as such provisions apply in

                           Schedule to this Deed and (in the case of Group
                           Shares, together with all Related Rights) are hereby
                           mortgaged or charged as provided in such provisions
                           and the other provisions of the Debenture.

4.       The Company, for itself and as agent for and on behalf of all other
         Chargors under the Debenture, hereby agrees to all matters provided for
         herein.

5.       The Debenture and this Deed shall be read as one to this extent and so
         that references in the Debenture to "this Debenture", "herein", and
         similar phrases shall be deemed to include this Deed and all references
