the Shelf Registration Statement or to use the prospectus forming a part thereof for resales of Registrable Securities unless such holder is an Electing Holder, and (y) after the Effective Time of the Shelf Registration Statement, promptly upon
the request of any holder of Registrable Securities that is not then an Electing Holder, to take any action reasonably necessary to enable such holder to use the prospectus forming a part thereof for resales of Registrable Securities, including,

 (xix) in the event that any broker-dealer registered under the Exchange Act shall underwrite any Registrable Securities or participate as

 (e) In the event that the
Company or the Guarantor would be required, pursuant to Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement or sales agent, if any, therefor and the managing underwriters, if any, thereof, the Company and the Guarantor
shall without delay prepare and furnish to each of the Electing Holders, to each placement or sales agent, if any, and to each such underwriter, if any, a reasonable number of copies of a prospectus supplemented or amended so that, as thereafter
delivered to purchasers of Registrable Securities, such prospectus shall conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and
shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. Each Electing Holder
agrees that upon receipt of any notice from the Company or the Guarantor pursuant to Section 3(d)(viii)(F) hereof, such Electing Holder shall forthwith discontinue the disposition of Registrable Securities pursuant to the Shelf Registration
Statement applicable to such Registrable Securities until such Electing Holder shall have received copies of such amended or supplemented prospectus, and if so directed by the Company, such Electing Holder shall deliver to the Company (at the
Company’s and the Guarantor’s joint expense) all copies, other than permanent file copies, then in such Electing Holder’s possession of the prospectus covering such Registrable Securities at the time of receipt of such notice.

 (f) In the event of a Shelf Registration, in addition to the information required to be provided by each Electing Holder in their
respective Notice Questionnaire, the Company may require such Electing Holder to furnish to the Company such additional information regarding such Electing Holder and such Electing Holder’s intended method of distribution of Registrable
Securities as may be required in order to comply with the Securities Act. Each such Electing Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Electing Holder to
the Company or of the occurrence of any event in either case as a result of which any prospectus relating to such Shelf Registration contains or would contain an untrue statement of a material fact regarding such Electing Holder or such Electing
Holder’s intended method of disposition of such Registrable Securities or omits to state any material fact regarding such Electing Holder or such Electing Holder’s intended method of disposition of such Registrable Securities required to
be stated therein or necessary to 
  

 -16- 

 make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the
Company any additional information required to correct and update any previously furnished information or required so that such prospectus shall not contain, with respect to such Electing Holder or the disposition of such Registrable Securities, an
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. 
 (g) Until the expiration of two years after the Closing Date, the Company and the Guarantor will not, and will not permit any of their respective
“affiliates” (as defined in Rule 144) to, resell any of the Securities that have been reacquired by any of them except pursuant to an effective registration statement under the Securities Act. 
 4. Registration Expenses. 
 The

shall reimburse such person for the full amount of the Registration Expenses so incurred, assumed or paid promptly after receipt of a request therefor. Notwithstanding the foregoing, the holders of the Registrable Securities being registered shall
pay all agency fees and commissions and underwriting discounts and commissions attributable to the sale of such Registrable Securities and the fees and disbursements of any counsel or other advisors or experts retained by such holders (severally or
jointly), other than the counsel and experts specifically referred to above. 
 5. Representations and Warranties. 
 Each of the Company and the Guarantor represent and warrant to, and agrees with, each Purchaser and each of the holders from time to time of Registrable
Securities that: 
 (a) Each registration statement covering Registrable Securities and each prospectus (including any preliminary or summary
prospectus) contained therein or furnished pursuant to Section 3(d) or Section 3(c) hereof and any further amendments or supplements to any such registration statement or prospectus, when it becomes effective or is filed with the
Commission, as the case may be, and, in the case of an underwritten offering of Registrable Securities, at the time of the closing under the underwriting agreement relating thereto, will conform in all material respects to the requirements of the
Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and at all times subsequent to the Effective Time when a prospectus would be required to be delivered under the Securities Act, other than from (i) such time as a notice has been given to holders of
Registrable Securities pursuant to Section 3(d)(viii)(F) or Section 3(c)(iii)(F) hereof until (ii) such time as the Company and the Guarantor furnish an amended or supplemented prospectus pursuant to Section 3(e) or
Section 3(c)(iv) hereof, each such registration statement, and each prospectus (including any summary prospectus) contained therein or furnished pursuant to Section 3(d) or Section 3(c) hereof, as then amended or supplemented, will
conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not contain an untrue statement of a material fact or omit to state a material

omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein. 
 (b) Any documents incorporated by reference in any prospectus referred to in Section 5(a) hereof, when they become or became effective or are or were filed with the Commission, as the case may be, will conform or
conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and none of such documents will contain or contained an untrue statement of a material fact or will omit or omitted to state a material
fact required to be stated therein or necessary to make the statements therein not misleading; 
  

 -18- 

 provided, however, that this representation and warranty shall not apply to any statements or omissions
made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein. 
 (c) The compliance by the Company and the Guarantor with all of the provisions of this Exchange and Registration Rights Agreement and the consummation of the transactions herein contemplated will not (i) conflict
with or result in a breach of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company, the Guarantor or any of their respective
subsidiaries is a party or by which the Company, the Guarantor or any of their respective subsidiaries is bound or to which any of the property or assets of the Company, the Guarantor or any of their respective subsidiaries is subject,
(ii) result in any violation of the provisions of the memorandum of association, as amended, or the articles of association of the Company or the Guarantor or (iii) result in any violation of any statute or any order, rule or regulation of
any court or governmental agency or body having jurisdiction over the Company, the Guarantor or any of their respective subsidiaries or any of their properties, except, in the cases of clause (i) or (iii), for such conflicts, breaches or
violations that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect (as defined in the Purchase Agreement); and no consent, approval, authorization, order, registration or qualification of or with
any such court or governmental agency or body is required for the consummation by the Company and the Guarantor of the transactions contemplated by this Exchange and Registration Rights Agreement, except the registration under the Securities Act of
the Securities, qualification of the Indenture under the Trust Indenture Act and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or blue sky laws in connection with the offering and
distribution of the Securities. 
 (d) This Exchange and Registration Rights Agreement has been duly authorized, executed and delivered by
the Company and the Guarantor. 
 6. Indemnification. 
 (a) Indemnification by the Company and the Guarantor. The Company and the Guarantor, jointly and severally, will indemnify and hold harmless each of the holders of Registrable Securities included in an Exchange
Registration Statement, each of the Electing Holders of Registrable Securities included in a Shelf Registration Statement and each person who participates as a placement or sales agent or as an underwriter in any offering or sale of such Registrable
Securities against any losses, claims, damages or liabilities, joint or several, to which such holder, agent or underwriter may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Exchange Registration Statement or Shelf Registration Statement, as the case may be, under which such Registrable
Securities were registered under the Securities Act, or any preliminary, final or summary prospectus contained therein or furnished by the Company or the Guarantor to any such holder, Electing Holder, agent or underwriter, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, 
  

 -19- 

 and will reimburse such holder, such Electing Holder, such agent and such underwriter for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that neither the Company nor the Guarantor shall be liable to any such person in any such
case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, or preliminary, final or summary
prospectus, or amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by such person expressly for use therein. 
 (b) Indemnification by the Holders and any Agents and Underwriters. The Company may require, as a condition to including any Registrable
Securities in any registration statement filed pursuant to Section 2(b) hereof and to entering into any underwriting agreement with respect thereto, that the Company shall have received an undertaking reasonably satisfactory to it from the
Electing Holder of such Registrable Securities and from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and hold harmless the Company, the Guarantor, and all other holders of Registrable
Securities, against any losses, claims, damages or liabilities to which the Company, the Guarantor or such other holders of Registrable Securities may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such registration statement, or any preliminary, final or summary prospectus contained therein
or furnished by the Company to any such Electing Holder, agent or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company by such Electing Holder or underwriter expressly for use therein, and (ii) reimburse the Company and the Guarantor for any legal or other expenses reasonably incurred by the Company and the Guarantor
in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that no such Electing Holder shall be required to undertake liability to any person under this Section 6(b) for any
amounts in excess of the amount of the proceeds to be received by such Electing Holder from the sale of such Electing Holder’s Registrable Securities pursuant to such registration. 
 (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of written notice of the
commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party pursuant to the indemnification provisions of or contemplated by this Section 6, notify such indemnifying party
in writing of the commencement of such action; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under the indemnification provisions of or
contemplated by Section 6(a) or 6(b) hereof. In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such 
  

 -20- 

 indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any
other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party,
effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified
party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and
(ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
 (d) Contribution. If for any reason the indemnification provisions contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims,
damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions
in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities
(or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were determined by pro rata allocation (even if the
holders or any agents or underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d). The amount paid
or payable by an indemnified party as a result of the losses, claims, damages, or liabilities (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), no holder shall be required to contribute any amount in excess of the amount by which the amount of the proceeds
received by such holder from the sale of any Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission, and no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of 
  

 -21- 

 such fraudulent misrepresentation. The holders’ and any underwriters’ obligations in this Section 6(d) to
contribute shall be several in proportion to the principal amount of Registrable Securities registered or underwritten, as the case may be, by them and not joint. 
 (e) The obligations of the Company and the Guarantor under this Section 6 shall be in addition to any liability which the Company or the Guarantor may otherwise have and shall extend, upon the same terms and
conditions, to each officer, director and partner of each holder, agent and underwriter and each person, if any, who controls any holder, agent or underwriter within the meaning of the Securities Act; and the obligations of the holders and any
agents or underwriters contemplated by this Section 6 shall be in addition to any liability which the respective holder, agent or underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director
of the Company or the Guarantor (including any person who, with his consent, is named in any registration statement as about to become a director of the Company or the Guarantor) and to each person, if any, who controls the Company within the
meaning of the Securities Act. 
 7. Underwritten Offerings. 
 (a) Selection of Underwriters. If any of the Registrable Securities covered by the Shelf Registration are to be sold pursuant to an underwritten
offering, the managing underwriter or underwriters thereof shall be designated by Electing Holders holding at least a majority in aggregate principal amount of the Registrable Securities to be included in such offering, provided that such designated
managing underwriter or underwriters is or are reasonably acceptable to the Company. 
 (b) Participation by Holders. Each holder of
Registrable Securities hereby agrees with each other such holder that no such holder may participate in any underwritten offering hereunder unless such holder (i) agrees to sell such holder’s Registrable Securities on the basis provided in
any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements. 
 8. Rule 144. 
 The Company and the Guarantor covenant to the holders of Registrable Securities that to the extent they shall be required to do so under the Exchange
Act, each shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Section 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the

provided that all payments of principal, premium, Additional Amounts and interest with respect to Securities the Holders of which have given wire transfer instructions to the Issuer prior to the Record Date will be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders thereof. Until otherwise designated by the Issuer, the Issuer’s offices or agencies in the City of New York and London, England will be the offices of the Trustee
maintained for such purpose. 

 SECTION 3. Paying Agent and Registrar. Initially, The Bank of New York will act as Paying Agent
and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer or any Affiliate may act in any such capacity. 
 SECTION 4. Indenture. The Issuer issued the Securities under an Indenture dated as of December 23, 2004 (“Indenture”) among the Issuer, Global Crossing (UK) Telecommunications Limited, STT
Communications Ltd., the Trustee and AIB/BNY Fund Management (Ireland) Limited. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the U.S. Trust Indenture Act of 1939, as amended
(15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”). The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this
Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 
 SECTION
5. Optional Redemption. (a) The Sterling Securities may be redeemed, at the Issuer’s option, in whole at any time or in part from time to time, on and after December 15, 2009 at the following redemption prices (expressed as
percentages of the principal amounts thereof) if redeemed during the twelve-month period commencing on December 15 of the applicable year set forth below, plus, in each case, accrued and unpaid interest, if any, to the date of redemption:

  

				
	 Year
	  	Percentage	 
	 2009
	  	105.875	%
	 2010
	  	103.917	%
	 2011
	  	101.958	%
	 2012 and thereafter
	  	100.000	%

 (b) Prior to December 15, 2009, the Issuer may redeem the Sterling Securities, at its option,
in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Amounts, if any to the redemption date, plus the Make-Whole Premium. 

“Applicable Rate” for any redemption date, means yield to maturity of UK Government securities with a fixed maturity from information
compiled by the Office for National Statistics and published in the most recent Financial Statistics that have become publicly available at least two Business Days in London prior to the make whole Redemption Date of such Sterling Security most
nearly equal to the period from the make-whole Redemption Date to December 15, 2009; provided, however, that if such Financial Statistics are no longer published or do not indicate the relevant yield to maturity at the time of
computation, the Issuer shall use any publicly available source of similar market data most nearly equal to the period from such Make-Whole Redemption Date to December 15, 2009; provided, further however, that if the period from
such Make-Whole Redemption Date to December 15, 2009 is not equal to the fixed maturity of U.K. Government Securities for which a yield is given, the Applicable Rate shall be obtained by linear interpolation (calculated to the nearest
one-twelfth of a year) from the yields of U.K. Government Securities for which such yields are given except that if the period from such redemption date 

 
to December 15, 2009 is less than one year, the Issuer shall use the weekly average yield on actually traded U.K. Government Securities denominated in
sterling adjusted to a fixed maturity of one year to make such calculation. 
 “Make-Whole Premium” means an amount equal to
the greater of (i) 1.0% of the principal amount of such Sterling Security and (ii) the excess of (x) the present value of the sum of the principal amount and premium, if any, that would be payable on such Sterling Security on
December 15, 2009 and all remaining interest payments to and including December 15, 2009 (but excluding any interest accrued to the Make-Whole Redemption Date), discounted on a semiannual basis (assuming a 360-day year consisting of twelve
30-day months) from December 15, 2009 to the Make-Whole Redemption Date at a per annum interest rate equal to the Applicable Rate on such Make-Whole Redemption Date plus 0.50%, over (y) the outstanding principal amount of such Sterling
Security. 
 “Make-Whole Redemption Date” with respect to a Make-Whole Redemption, means the date such Make-Whole Redemption
is effected. 
 SECTION 6. Optional Redemption upon Equity Offering. At any time, or from time to time, prior to December 15,
2007, the Issuer may, at its option, use all or any portion of the net cash proceeds of one or more Equity Offerings (as defined below) to redeem up to 35% of the aggregate principal amount of the Sterling Securities issued at a redemption price
equal to 111.750% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of redemption; provided that at least 65% of the aggregate principal amount of Sterling Securities originally issued remains outstanding
immediately after any such redemption. In order to effect the foregoing redemption with the proceeds of any Equity Offering, the Issuer shall consummate such redemption not more than 120 days after the consummation of any such Equity Offering.

 “Equity Offering” means any issuance of, or contribution on account of, Qualified Capital Stock of the Company.

 SECTION 7. Redemption for Changes in Withholding Taxes. The Issuer is entitled to redeem the Sterling Securities, at its option, at
any time as a whole but not in part, upon not less than 30 nor more than 60 days’ notice, at a price equal to 100% of the outstanding principal amount thereof, plus accrued and unpaid interest (if any) to the date of redemption (subject to the
right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event the Issuer has become or would become obligated to pay, on the next date on which any amount would be payable with
respect to the Securities, any Additional Amounts as a result of: 
 (1) a change in or an amendment to any laws or treaties
(including any rulings or regulations promulgated thereunder) of any relevant Taxing Jurisdiction (or any political subdivision or taxing authority thereof or therein); or 
 (2) any change in or amendment to any official position regarding the application, administration or interpretation of such laws,
treaties, rulings or regulations, which change or amendment is announced or becomes effective on or after the Issue Date, 

 and the Issuer cannot avoid such obligation by taking reasonable measures available to it, provided that the
Issuer shall not be required to take any measures that, in its reasonable determination, would result in the imposition on it of any legal or regulatory burden or the incurrence by it of any additional costs, or would otherwise result in any adverse
consequences. The foregoing provisions will apply mutatis mutandis to the laws and official positions of any jurisdiction in which any successor permitted under Section 5.01 of the Indenture is organized, but (in the case of any
jurisdiction other than Ireland) only with respect to events arising after the date of succession to the extent the foregoing did not apply to such events prior to the date of succession. 
 Before publishing or mailing notice of redemption of the Securities, the Issuer will deliver to the Trustee an Officers’ Certificate to the effect
that the Issuer cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it. The Issuer will also deliver an opinion of independent legal counsel of recognized standing to the extent that the Issuer would be
obligated to pay Additional Amounts as a result of a change or amendment described above. 
 SECTION 8. Mandatory Redemption.
For the avoidance of doubt, an offer to purchase pursuant to Section 9 hereof shall not be deemed a redemption. The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities.

 SECTION 9. Offers To Purchase. The Indenture provides that upon the occurrence of a Change of Control or an Asset Sale and subject
to further limitations contained therein, the Issuer shall make an offer to purchase outstanding Securities in accordance with the procedures set forth in the Indenture. 
 SECTION 10. Optionholder’s Right to Purchase. Pursuant to Section 3.07 of the Indenture, if an Event of Default of the type described in Section 6.01(1) or Section 6.01(2) of the
Indenture has occurred and is continuing, or upon enforcement action taken by the Trustee, the Optionholder has the right, but not the obligation, to purchase all of the Securities then outstanding. Reference is hereby made to the Indenture for a
statement of the respective rights, limitations of rights, duties and obligations thereunder of the Optionholder, the Issuer, the Guarantor, the Trustee and Holders in respect of the Purchase Option. 
 SECTION 11. Notice of Redemption. Notice of redemption will be mailed by first class mail at least 30 days but not more than 60 days before the
redemption date to each Holder of Securities to be redeemed at its registered address. Sterling Securities in denominations larger than £50,000 may be redeemed in part. If any Sterling Security is to be redeemed in part only, the notice of
redemption that relates to such Sterling Security shall state the portion of the principal amount thereof to be redeemed. A new Sterling Security in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Sterling Security. On and after the redemption date interest ceases to accrue on Sterling Securities or portions thereof called for redemption. 

 SECTION 12. Denominations, Transfer, Exchange. The Sterling Securities are in registered form
without coupons in denominations of £50,000 and integral multiples of £1,000. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer or the Registrar is not required to transfer or
exchange any Sterling Security selected for redemption. The Company or the Registrar is not required to transfer or exchange any Sterling Securities for a period of 15 days before a selection of Sterling Securities to be redeemed. 
 SECTION 13. Persons Deemed Owners. The registered Holder of a Sterling Security may be treated as its owner for all purposes. 
 SECTION 14. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture and the Sterling Securities may be amended or
supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and any existing Default or compliance with any provision may be waived with the consent of the Holders of
a majority in aggregate principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect
or inconsistency in the Indenture, provide for uncertificated Sterling Securities in addition to certificated Sterling Securities, comply with any requirements of the Commission in connection with the qualification of the Indenture under the TIA, or
make any change that does not adversely affect the rights of any Holder of a Security; provided, however, that if any amendment, waiver or other modification will only affect the Dollar Securities or the Sterling Securities, only the
consent of the Holders of at least a majority in principal amount of the then outstanding Dollar Securities or Sterling Securities (and not the consent of at least a majority of all Securities), as the case may be, shall be required. 
 SECTION 15. Defaults and Remedies. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate
principal amount of the then outstanding Securities generally may declare all the Securities to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency
as set forth in the Indenture, with respect to the Company or the Issuer, all outstanding Securities will become due and payable without further action or notice. Holders of the Securities may not enforce the Indenture or the Securities except as
provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders
notice of any continuing Default (except a Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Securities then
outstanding by notice to the Trustee may on 

 
behalf of the Holders of all of the Securities waive any Default and its consequences under the Indenture except a continuing Default in the payment of
interest on, or the principal of the Securities or in respect of certain covenants set forth in the Indenture. 
 SECTION 16. Restrictive
Covenants. The Indenture contains certain covenants that, among other things, limit the ability of the Company and its Restricted Subsidiaries to make restricted payments, to incur indebtedness, to create liens, to sell assets, to permit
restrictions on dividends and other payments by Restricted Subsidiaries of the Company, to consolidate, merge or sell all or substantially all of its assets or to engage in transactions with affiliates. The limitations are subject to a number of
important qualifications and exceptions. The Company must annually report to the Trustee on compliance with such limitations. 
 SECTION 17.
No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Issuer or any direct or indirect parent corporation or any Guarantor, as such, shall have any liability for any obligations of the Issuer or the
Guarantors under the Securities, the Indenture, the Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Securities by accepting a Security waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Securities. 
 SECTION 18. Trustee Dealings with the Company.
The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

 SECTION 19. Authentication. This Sterling Security shall not be valid until authenticated by the manual signature of the Trustee or
an authenticating agent.

such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

the Guarantors, the Trustee, the respective other parties thereto and the Holders. 

 SECTION 23. Additional Amounts. The Holder of this Sterling Security will be entitled to
Additional Amounts in certain circumstances pursuant to the Indenture. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Issuer, the Guarantors, the
Trustee and Holders in respect of Additional Amounts. 
 SECTION 24. ISINs and Common Codes. The Issuer has caused ISINs and Common
Codes to be printed on the Sterling Securities and has directed the Trustee to use ISINs and Common Codes in notices of redemption as a convenience to the Holders. No representation is made as to the accuracy of such numbers either as printed on the
Sterling Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
 SECTION 25. Governing Law. This Security shall be governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the
application of the law of another jurisdiction would be required thereby.  
 The Issuer will furnish to any Holder upon written request
and without charge a copy of the Indenture.
