	 	(iv)	any lease, license, governmental authorization, permit, concession, contract, property rights, application or agreement to which any Chargor is a party (or to any of its rights or
interests thereunder) if the grant of such charge would constitute or result in either (A) the abandonment, invalidation or unenforceability of any right, title or interest of any Chargor therein or (B) a breach, cancellation, withdrawal

provided that the foregoing shall not be applicable to the extent that such costs shall not be greater than $80,000 with respect to Liens being taken on the Issue Date, or not be greater than $80,000 during any calendar year with respect to Liens

interests thereunder) if the grant of such charge would constitute or result in either (A) the abandonment, invalidation or unenforceability of any right, title or interest of any Chargor therein or (B) a breach, cancellation, withdrawal
or termination pursuant to the terms of, or a default under, any such lease, license, governmental authorization, permit, concession, contract, property rights application or agreement (except to the extent that any such term would be rendered
ineffective pursuant to, or any such breach, cancellation, withdrawal or termination would be overridden by applicable law); 

  

	 	(v)	without limiting the provisions of the Indenture, to any Property of the Chargors, in any jurisdiction, to the extent that obtaining a Lien upon such Property in such jurisdiction

provided that the foregoing shall not be applicable to the extent that such costs shall not be greater than $80,000 with respect to Liens being taken on the Issue Date, or not be greater than $80,000 during any calendar year with respect to Liens
being taken after the Issue Date; and (b) such Property is immaterial in relation to the aggregate value of the Property of all of the Chargors in which the Collateral Agent is obtaining a valid, perfected and enforceable Lien and is not a
necessary link or equipment (assuming no cable or fiber capacity or rights thereto are available from any other provider) to enable any Material Subsidiary to conduct any material portion of its operations or business; 

  

	 	(vii)	any Property, where such Property consists of a parcel of real property or real property interests and the aggregate cost of obtaining and maintaining a Lien upon such Property
(including all recording and stamp fees, taxes and notary fees but excluding any costs that arise at the time of the enforcement of such Lien) are reasonably estimated to exceed 5% of the aggregate Fair Market Value of such parcel and shall be
greater than $80,000 with respect to Liens being taken on the Issue Date, and greater than $80,000 during any calendar year with respect to Liens being taken after the Issue Date, or greater than $30,000 for any individual parcel of Property (such
latter estimate to be taken as an average of the costs of taking Liens on all parcels of real property or real property interests on the Issue Date and thereafter, and not on the cost of obtaining a Lien on any particular parcel) and such Property
is immaterial in relation to the aggregate value of the Property of all of the Chargors in which the Collateral Agent is obtaining a valid, perfected and enforceable Lien and is not a necessary link (assuming no cable or fiber capacity or rights
thereto are available from any other provider) to enable any Material Subsidiary to conduct any material portion of its operations or business; or

Property hereunder and any requirement contained in the Indenture or any other Security Document, until notice to the Chargors has been given by the Collateral Agent after the occurrence of an Event of Default which is continuing, unremedied and
unwaived, each Chargor shall have the right to exploit and use the Intellectual Property in connection with its business, including but not limited to the development, marketing, promotion, distribution and sale of the underlying sources related to

the Land Registration Acts 1925 to 1988, acquired by or on behalf of a Chargor after the execution of this Debenture, that Chargor shall promptly notify the Collateral Agent of the title number(s) and, contemporaneously with the making of an

consent of the Collateral Agent, any Chargor 



  

 7 









	 	 
may remove items of Charged Property outside of England and Wales in order to have them repaired or upgraded, subject to the obligation of returning such
items to their original location in England and Wales as soon as their repair or upgrade has been completed and, if required in order to transport or relocate any such item of Charged Property, the Collateral Agent shall, upon delivery to it of a
request in writing requesting a release (which shall state that such release is authorized under this Clause 5.6) (and such other documents as are required pursuant to the Indenture), promptly execute and deliver to such Chargor such release
statement and such other documentation as shall be specified by such Chargor in such written request to effect the temporary release of the Lien on the Charged Property in order that it may be removed or relocated. 


  

	 	(b)	Until an Event of Default has occurred and is continuing, unremedied and unwaived and notice thereof has been given to the Chargors, nothing contained in this Debenture shall be
deemed to restrict the ability and right of the Chargor to, in the ordinary course of business and so long as the rights of the Collateral Agent under this Debenture shall not be adversely affected thereby, modify the contractual terms of any
agreement or instrument, including, without limitation, its ability to revise or cancel its contracts or invoices and in general maintain a normal commercial relationship with each counterparty to any agreement or instrument, including the right to
terminate any agreement or instrument, all in accordance with normal commercial practices.

assignment over all or any of the assets constituting, or intended to constitute, Charged Property) or for the exercise of the Collateral Rights; 

  


	 	(b)	to confer on the Collateral Agent the security interest intended to be conferred by or pursuant to this Debenture over any Charged Property of a Chargor located in any jurisdiction
outside England and Wales; and/or

Debenture. 

  
 Furthermore and for greater clarity, each Chargor
will (subject to the Indenture) take or cause to be taken all action required to maintain, preserve and protect the Liens on the Charged Property granted by this Debenture, including causing this Debenture, instruments of further assurance and all
amendments or supplement thereto, to be promptly recorded, registered and filed and at all times to be kept recorded, registered and filed, and will execute and file statements and cause to be issued and filed statements, all in such manner and in
such places and at such times as are prescribed in this Debenture and as may be required by law fully to preserve and protect the rights of the Secured Parties and the Collateral Agent under this Debenture to the Charged Property.

liable for any deficiency. 
  
 11.2    Lien
Held by Chargor    A Chargor will not without the prior written consent of the Collateral Agent hold any Lien, guarantee, indemnity, bond or other assurance from any other person in respect of the

	 	(c)	this Debenture constitutes its legal, valid and binding obligation and creates an effective fixed or floating charge, as applicable, over the Charged Property, subject to applicable
bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law; 


 

	 	(d)	The entry into and performance by it of, and the transactions contemplated by, this Debenture do not and will not conflict with: 

  

	 	(i)	any law or regulation or judicial or official order applicable to it; or 

  

	 	(ii)	its constitutional documents; or 

  

	 	(iii)	any material agreement or document which is binding upon it or any of its assets or result in the creation of (or a requirement for the creation of) any Security over any Charged

	 	(a)	enforce all or any part of that security (at the times, in the manner and on the terms set forth in this Debenture) and take possession of and hold or, upon 10 Business Days’
prior written notice to such Chargor, dispose of all or any part of the Charged Property; and 

  

	 	(b)	whether or not it has appointed a Receiver, exercise all or any of the powers, authorities and discretions conferred by the Law of Property Act 1925 (as varied or extended by this
Debenture) on mortgagees and by this Debenture on any Receiver or otherwise conferred by law on mortgagees or Receivers, provided that the Collateral Agent or any Receiver may not exercise any powers, authorities or discretions to sell or otherwise
dispose of all or any part of the Charged Property unless the Collateral Agent or such Receiver has given 10 Business Days’ prior written notice of such proposed sale or disposition to the relevant Chargor. 

  
 A certificate in writing by an officer or agent of the Collateral Agent that any power of
sale or other disposal has arisen and is exercisable shall be conclusive evidence of that fact in favour of a purchaser of all or any part of the Charged Property. 
  
 13.2    Immediate Recourse    The Collateral Agent shall not be required to
proceed against or enforce any other rights or security it may have or hold in respect of the Secured Obligations or claim payment from any other person before enforcing the security constituted by this Debenture and each Chargor waives any right it
may have of first requiring the Collateral Agent to do so. 
  
 13.3    No Liability as Mortgagee in Possession    Neither the Collateral Agent nor any Receiver shall be liable to account as a mortgagee in possession in respect of all or any part of the

be liable, except for cases of gross negligence, wilful misconduct, fraud or dishonesty.

pursuant to this Debenture 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 Charged Property or any part of them. The Collateral Agent and any such Receiver
may retain and pay all sums in respect of which it is indemnified out of any monies received by it under the powers conferred by this Debenture. 
  
 13.5    No Competition    Until all the Secured Obligations have been unconditionally and irrevocably
discharged in full, any rights (if any) which each Chargor may have: 
  

	 	(a)	to be subrogated to any rights or security of or moneys held, received or receivable by the Collateral Agent or any Holder (or any agent or trustee on its behalf) with respect to
the Secured Obligations; or 

  

	 	(b)	to be entitled to any right of contribution or indemnity from any other person; or 

  

	 	(c)	to claim, rank, prove or vote as a creditor of such other person or its estate in competition with the Collateral Agent or any Holder (or any agent or trustee on its behalf),


  
 shall be exercised by a Chargor only if and to the extent that
the Collateral Agent so requires and in such manner and upon such terms as the Collateral Agent may specify and a Chargor shall hold any moneys, rights or security held or received by it as a result of the exercise of any such rights on trust for
the Collateral Agent for application in accordance with the terms hereof as if such moneys, rights or security were held or received by the Collateral Agent under this Debenture. 
  
 13.6    Appropriations    Until all the Secured Obligations have been
unconditionally and irrevocably paid and discharged in full in cash, the Collateral Agent may: 
  

	 	(a)	if it believes the Secured Obligations may not be repaid in full refrain from applying or enforcing any other moneys, security or rights held or received by it in respect of the
Secured Obligations or apply and enforce the same in such manner and order as it sees fit (whether against the Secured Obligations 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 a Chargor or any other person in respect of the Secured Obligations. 

  
 13.7    Small Company
Moratorium    Notwithstanding any other provision of this Debenture, the obtaining of a moratorium under section 1A of the Insolvency Act 1986, or anything done with a view to obtaining such a moratorium (including any
preliminary decision or investigation), shall not be an event causing any floating charge created by this deed to crystallise or causing restrictions which would not otherwise apply to be imposed on the disposal of property by any Chargor or a
ground for the appointment of a Receiver. 
  
 14.    EXTENSION AND VARIATION OF THE LAW OF PROPERTY ACT 1925 
  
 14.1    Extension of Powers    The power of sale or other disposal conferred on the Collateral Agent and on
any Receiver by this Debenture shall operate as a variation and extension of the statutory power of sale under Section 101 of the Law of Property Act 1925 and such power shall arise (and the Secured Obligations shall be deemed due and payable
for that purpose) on execution of this Debenture. 
  
 14.2    Restrictions    The restrictions contained in Sections 93 and 103 of the Law of Property Act 1925 shall not apply to this Debenture or to the exercise by the Collateral Agent of its
right to consolidate all or any of the security created by or pursuant to this Debenture with any other security in existence at any time or to its power of sale, which powers may be exercised by the Collateral Agent without notice to a Chargor at
any time after the occurrence of an Event of Default which is continuing, unremedied and unwaived. 
  
 14.3    Power of Leasing    The statutory powers of leasing may be exercised by the Collateral Agent at any

 12 








 
make any lease or agreement for lease, accept surrenders of leases and grant options on such terms as it shall think fit, without the need to comply with any
restrictions imposed by Sections 99 and 100 of the Law of Property Act 1925.

	 	(c)	entitled to remuneration for his services by the Chargors (with the Chargors jointly and severally liable for such remuneration) at a rate to be fixed by the Collateral Agent from
time to time (without being limited to the maximum rate specified by the Law of Property Act 1925).

 20.1    Continuing Security    The Liens created by or pursuant to this Debenture shall remain in full
force and effect as a continuing security for the Secured Obligations unless and until the Secured Obligations have been paid in full, or otherwise discharged or released, and shall not cease by reason of any intermediate payment or intermediate
satisfaction of all or any of the Secured Obligations or for any other reason, however, if the obligations of a Chargor under this Debenture cease to be continuing for any reason the liability of that Chargor at the date of such cessation shall
remain regardless of any subsequent increase or reduction in the Secured Obligations. 
  
 20.2    Breaking of Accounts    If for any reason the security constituted hereby ceases to be a continuing security in respect of a Chargor (other than by way of
discharge of such security in accordance with the terms of this Debenture) or the Collateral Agent or any other Holder receives, or is deemed to be affected by, notice, whether actual or constructive of any Lien affecting the Charged Property, the
Collateral Agent may open a new account with or continue any existing account with the Chargor. If the Collateral Agent does not open a new account, it shall nevertheless be treated as if it had done so at the date of such cessation or the time when
it received or was deemed to have received notice. As from that time all payments made to the Collateral Agent will be deemed to be credited or treated as being credited to the new account and the liability of the Chargor in 

  

 14 








 
respect of the Secured Obligations relating to it at the date of such cessation or the time when notice was received or deemed received shall remain and
shall not be reduced regardless of any payments into or out of any such account. 
  
 20.3    Cumulative Rights 
  

	 	(a)	The Liens created by or pursuant to, and the rights and remedies of the Collateral Agent in, this Debenture and the Collateral Rights and the obligations, representations and
warranties of each Chargor in this Debenture shall be cumulative, in addition to and independent of every other security, right or remedy which the Collateral Agent may at any time hold or have for the Secured Obligations or any other obligations or
any rights, powers and remedies, or obligations, representations or warranties of each Chargor, conferred, provided or imposed by law, the Indenture or any other Security Document. 

  

	 	(b)	No prior security held by the Collateral Agent (whether in its capacity as trustee or otherwise) or any of the other Secured Parties over the whole or any part of the Charged
Property shall merge into the security constituted by this Debenture. 

  

	 	(c)	Without limiting the generality of the foregoing in this Clause 20.3, if any provision hereof covers the same subject matter as a provision of the Indenture, then all such
provisions shall be liberally construed in favour of the Collateral Agent and the Secured Parties both with respect to the rights and remedies available to the Collateral Agent and the Secured Parties and the obligations, representations and
warranties to be fulfilled or made by each Chargor. 

  
 20.4    No Prejudice    The Liens created by or pursuant to this Debenture and the Collateral Rights shall not be prejudiced by any unenforceability or invalidity of any other agreement or
document or by any time or indulgence granted to a Chargor or any other person, or the Collateral Agent (whether in its capacity as trustee or otherwise) or any of the other Secured Parties or by any variation of the terms of the trust upon which
the Collateral Agent holds the security or by any other thing which might otherwise prejudice that security or any Collateral Right. 
  
 20.5    Remedies and Waivers    No delay in exercising, any right, power or remedy hereunder shall operate
as a waiver thereof; nor shall any single or partial exercise by the Collateral Agent of any right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The Collateral Agent
shall not be required to exercise any right, power or remedy against any other Person, or under any other Security Document, as a condition to exercising any right, power or remedy against any Chargor hereunder, and no such exercise of any right,
power or remedy against any other Person, or under any other Security Document, shall constitute a waiver of or otherwise preclude the Collateral Agent from exercising any right, power or remedy against any Chargor hereunder. 
  
 20.6    No Liability    None
of the Collateral Agent, its nominee(s) or any Receiver shall be liable by reason of (a) taking any action permitted by this Debenture or (b) any neglect or default in connection with the Charged Property or (c) taking possession of
or realising all or any part of the Charged Property, except in the case of gross negligence, wilful misconduct, fraud or dishonesty. 
  
 20.7    Partial Invalidity    If, at any time, any provision of this Debenture is or becomes illegal,
invalid or unenforceable in any respect under the law of any jurisdiction, neither the legality, validity or enforceability of the remaining provisions of this Debenture nor of such provision under the laws of any other jurisdiction shall in any way
be affected or impaired thereby and, if any part of the Liens intended to be created by or pursuant to this Debenture is invalid, unenforceable or ineffective for any reason, that shall not affect or impair any other part of the security.

  
 21.    RELEASE OF SECURITY 
  
 21.1    Redemption of
Security    When all Secured Obligations shall have been paid in full or otherwise discharged or released, this Debenture shall automatically terminate and any powers of attorney granted hereby will be automatically
terminated (notwithstanding anything to the contrary in Clause 19) and the Collateral Agent shall, when the requirements of the Indenture have been met, forthwith cause to be assigned, transferred and delivered, against receipt but without any
recourse, warranty or representation whatsoever, any and all Charged Property and money received in respect thereof, to or on the order of the Chargor. The Collateral Agent shall, at the expense of the Chargor, also execute and deliver to the
Chargor upon such termination such termination statements and such other documentation as shall be reasonably requested by the respective Chargor to effect the termination and release of the Liens on the Charged Property. 
  

 15 








 21.2    Avoidance of Payments 
  

	 	(a)	No amount paid, repaid or credited to the Collateral Agent or a Holder shall be deemed to have been irrevocably paid if the Collateral Agent considers that the payment or credit of
such amount is capable of being avoided or reduced because of any laws applicable on bankruptcy, insolvency, liquidation or any similar laws. 

  

	 	(b)	If any amount paid, repaid or credited to the Collateral Agent or a Holder is avoided or reduced because of any laws applicable on bankruptcy, insolvency, liquidation or any similar
laws then any release, discharge or settlement between that Collateral Agent or Holder and the relevant Chargor shall be deemed not to have occurred and the Collateral Agent shall be entitled to enforce this Debenture subsequently as if such
release, discharge or settlement had not occurred and any such payment had not been made. 

  
 21.3    Releases of Security in Connection with Permitted Transactions 
  

	 	(a)	If, at any time, a Chargor consummates an Asset Sale in accordance with the terms of the Indenture, and satisfies all of the conditions precedent set forth in the Indenture with
respect thereto, the Collateral Agent shall, upon the request and at the expense of the Chargor (but without any recourse, warranty or representation whatsoever), execute, deliver or acknowledge any necessary or proper instruments of termination,
satisfaction or release (prepared by the Chargor) reasonably required to effect the release of the Liens on the Charged Property which is the subject of such Asset Sale. 

  

	 	(b)	At any time any Chargor sells, transfers, leases, conveys, substitutes, converts, abandons or otherwise disposes of any item of Charged Property in a transaction permitted under the
Indenture and for which such Chargor has complied with all requirements in respect of the Indenture (each such transaction, a “Permitted Sale”), any Lien on such Charged Property item shall be automatically released and, if a
formal, documented termination of release shall be necessary, the Collateral Agent shall at the expense of the Chargor (but without any recourse, warranty or representation whatsoever), upon delivery to it of a request in writing requesting such
release (which shall state that such release is authorized under this Clause), promptly execute and deliver to such Chargor upon the occurrence of such Permitted Sale such termination or release statements and such other documentation as shall be
specified by the such Chargor in such request in writing to effect the termination and release of the Liens on the Charged Property which is the subject of the Permitted Sale. 

  
 22.    ASSIGNMENT

recovery pursuant to any judgment or otherwise, expressed in or converted into any other currency, except to the extent that such tender or recovery results in the effective receipt by the Collateral Agent and the Secured Parties of the full amount
of the currency expressed to be payable under this Debenture. 
  
 24.4    Currency Indemnity    If any sum due from a Chargor under this Debenture (a “Sum”), or any order, judgment or award given or made in relation to a Sum, has to be

liability arising out of or as a result of the conversion including any discrepancy between (A) the rate of exchange used to convert that Sum from the First Currency into the Second Currency and (B) the rate or rates of exchange available
to the Collateral Agent and the Secured Parties at the time of its receipt of that Sum. 
  
 24.5    Indemnity    Without limiting the generality of the Indenture, but subject to Clause 13.4 (Indemnity—Charged Property), each Chargor shall,
notwithstanding any release or discharge of all or any part of the security, indemnify the Collateral Agent, its agents, attorneys and any Receiver against any action, proceeding, claims, losses, liabilities and costs which it may sustain as a
consequence of any breach by any Chargors of the provisions of this Debenture except to the extent resulting from the gross negligence, wilful misconduct, fraud or dishonesty of the Collateral Agent, its agents, attorneys or any Receiver, the
exercise or purported exercise of any of the rights and powers conferred on them by this Debenture or otherwise relating to the Charged Property. 
  
 25.    DELEGATION 
  
 Each of the Collateral Agent and any Receiver shall have full power to delegate (either generally or specifically) the powers, authorities and discretions
conferred on it by this Debenture (including the power of attorney) on such terms and conditions as it shall see fit which delegation shall not preclude either the subsequent exercise of such power, authority or discretion by the Collateral Agent or
the Receiver itself or any subsequent delegation or revocation thereof.
