                                         WESTMINSTER BANK PLC registered in England with company number 929027 whose registered
                                         office is at 135 Bishopsgate, London, EC2M 3UR (the Principal Employer); and

                                         office as at 1 Princes Street, London, EC2R 8PB (Trustee).

 

BACKGROUND:

 

		(A)	The Trustee
                                         is the trustee of the Royal Bank of Scotland Group Pension Fund (the Group Fund)
                                         as governed by a definitive deed dated 5 April 2006 and as amended from time to time
                                         (the Trust Deed and Rules).

 

		(B)	The Principal
                                         Employer is the principal employer of the Group Fund.

 

		(C)	The Principal
                                         Employer and the Trustee wish to agree their understanding in relation to a one-off capital
                                         contribution to the Group Fund in this Memorandum of Understanding (MoU).

 

		(D)	This
                                         MoU applies only to the Main Fund Section of the Group Fund.

 

		1.	AGREEMENT
                                         TO THIS MOU

 

In
consideration of the Principal Employer making a capital contribution to the Main Fund Section of the Group Fund of £4,200,000,000
on or before 30 March 2016 (the Contribution), the Trustee agrees to the provisions of this MoU to the extent that its
obligations hereunder do not conflict with its obligations under law or with its fiduciary duties to the Group Fund membership.

 

		2.	TRUSTEE
                                         FIDUCIARY DUTIES AND PENSIONS REGULATOR

 

The
Principal Employer acknowledges that the Trustee cannot fetter the exercise of its powers and discretions in a way which would
be inconsistent with its fiduciary duties and so the agreement of the Trustee recorded in this MoU must be read subject to that
principle. The Principal Employer also recognises that the Trustee’s fiduciary duties may include taking into account the
views of the Pensions Regulator (including Pensions Regulator guidance and codes of practice) and so the agreement of the Trustee
recorded in this MoU must be read subject to this. However the Trustee also confirms that as at the date of this MoU (i) it is
satisfied that entry into this MoU is consistent with its fiduciary duties and Pensions Regulator guidance and codes of practice
and (ii) it is not aware of any views of the Pensions Regulator which would conflict with the terms of this MoU.

 

		3.	BANK
                                         AND TRUSTEE TO ACT REASONABLY AND IN GOOD FAITH

 

By
entering into this MoU and in carrying out their obligations hereunder the Principal Employer and the Trustee shall act reasonably
and in good faith.

 

    	 

    	 

    

		4.	ADVANCE
                                         PAYMENT OF DEFICIT REPAIR CONTRIBUTIONS IN RESPECT OF 2014 SCHEDULE OF CONTRIBUTION

 

The
Trustee agrees that the Contribution is an advance payment of all the outstanding deficit repair contributions due to the Main
Fund Section of the Group Fund set out in the relevant schedule of contributions dated 27 June 2014 (the Schedule of Contributions)
and that no such further payments of deficit repair contributions will fall due to the Main Fund Section under that part of the
Schedule of Contributions. For the avoidance of doubt, the normal employer contributions, PPF and Pensions Regulator levies, augmentations
and other such additional payments as specified in the Schedule of Contributions and thereafter in the next schedule of contributions
to be agreed for the purposes of section 227 of the Pensions Act 2004 shall continue to be paid in respect of the Main Fund Section.

 

		5.	ACTUARIAL
                                         VALUATION DATES

 

		5.1	The Trustee
                                         agrees to obtain an actuarial valuation of the Main Fund Section of the Group Fund for
                                         the purposes of section 224 of the Pensions Act 2004 with an effective date to be agreed
                                         by the Principal Employer and the Trustee which must be between 31 October 2015 and 31
                                         December 2015 (the 2015 Valuation).

 

		5.2	Subject
                                         to sub-clause ‎5.3, the Trustee agrees not to obtain a further actuarial valuation
                                         of the Main Fund Section of the Group Fund for the purposes of section 224 of the Pensions
                                         Act 2004 (the Next Valuation) with an effective date earlier than three years
                                         after the effective date of the 2015 Valuation.

 

		5.3	The trust
                                         deed of the Group Fund (clause 6.9 of the trust deed) provides for the Trustee to obtain
                                         an actuarial valuation every three years or at such intervals as the Principal Employer
                                         may determine. The Trustee recognises that in the normal course of business funding levels
                                         may fluctuate before the effective date of the Next Valuation and at the date of signing
                                         this MOU the Trustee does not anticipate future circumstances which will require it to
                                         request an actuarial valuation at a date earlier than the effective date of the Next
                                         Valuation. However, where a material change arises and the Trustee requests consent for
                                         a valuation earlier than the Next Valuation the Principal Employer shall consider the
                                         request reasonably and in good faith as expressed in clause ‎3.

 

		6.	2015
                                         VALUATION AND RECOVERY PLAN

 

		6.1	The Trustee
                                         will agree with the Principal Employer before the Contribution the statement of funding
                                         principles in respect of the 2015 Valuation for the purposes of section 223 of the Pensions
                                         Act 2004.

 

		6.2	The actuarial
                                         assumptions for the 2015 Valuation contained in the statement of funding principles will
                                         be such that the technical provisions for the purposes of section 225 of the Pensions
                                         Act 2004 are no greater than the technical provisions would have been if the assumptions
                                         used were consistent with those used for the last actuarial valuation of the Main Fund
                                         Section of the Group Fund as at 31 March 2013.

 

		6.3	The Trustee
                                         further will agree with the Principal Employer before the Contribution that:

 

		(a)	the
                                         assumptions will be such that the Main Section of the Group Fund will meet the statutory
                                         funding objective (as defined in section 222 of the Pensions Act 2004) as at the effective
                                         date of the 2015 Valuation; or

 

		(b)	to
                                         the extent the 2015 Valuation shows that the statutory funding objective in respect of
                                         the Main Section of the Group Fund was not met as at the effective date of the 2015 Valuation,

                                         

                                         

                                         the recovery plan will be revised (for the purpose of section 226 of the Pensions Act
                                         2004)

 

    	 

    	 

    

to
be of such length and based on such assumptions as are necessary to allow the shortfall to be met from the Contribution without
further deficit repair contributions from the participating employers.

 

		6.4	The Trustee
                                         and the Principal Employer will take all actions necessary to finalise the 2015 Valuation
                                         by 30 June 2016.

 

		6.5	The Trustee
                                         shall set an investment strategy to meet the requirements of the recovery plan in sub-clause
                                         ‎6.3(b) above, with the intention of maintaining an investment strategy until
                                         the effective date of the Next Valuation at the earliest to meet the recovery plan in
                                         sub-clause ‎6.3(b) above, subject to the investment strategy remaining within
                                         the risk appetite set by the Trustee. Any material change to the investment strategy
                                         or risk appetite, should the Trustee consider this to be necessary for whatever reason,
                                         shall be subject to the provisions of clause ‎7. Such material change shall
                                         be reflected in an updated statement of investment principles in respect of which the
                                         Trustee acknowledges the continuing requirement to consult with the Principal Employer.

 

		6.6	The Trustee
                                         undertakes to discuss this MoU with the actuary appointed to the Group Fund under section
                                         47 of the Pensions Act 1995 (the Actuary). The Trustee will use reasonable endeavours
                                         to obtain confirmation in principle from the Actuary before the Contribution that he
                                         will be able to certify the technical provisions for the purposes of section 225 of the
                                         Pensions Act 2004 and the schedule of contributions for the purposes of section 227 of
                                         the Pensions Act 2004 in respect of the 2015 Valuation on the basis set out in this MoU.
                                         The Trustee will notify the Principal Employer in writing before the Contribution that
                                         the Actuary has provided such confirmation in principle.

 

		7.	INVESTMENT
                                         STRATEGY AND RISK MANAGEMENT

 

The
Trustee recognises the financial interest of the Principal Employer in the Group Fund, and the commitment that the Principal Employer
has made to funding the Group Fund by way of the Contribution. In consideration of this, the Trustee agrees (subject to (i) its
obligations under law and in particular the Pensions Act 1995 and the Occupational Pension Schemes (Investment) Regulations 2005
and (ii) to the provisions of the Trust Deed and the Rules) that:

 

		(a)	it
                                         will give full and proper consideration to any investment strategy and risk management
                                         proposal made by the Principal Employer to the Trustee;

 

		(b)	it
                                         will give full and proper consideration to the impact that any investment decision of
                                         the Trustee may make in relation to the participating employers where information regarding
                                         the potential impact has been made available to the Trustee;

 

		(c)	it
                                         will liaise closely with the Principal Employer in relation to its investment policy
                                         and decisions from time to time.

 

		8.	DISTRIBUTIONS
                                         AND OTHER CORPORATE ACTIONS

 

		8.1	The Trustee
                                         acknowledges that from time to time the Principal Employer and/or any participating employer
                                         may decide to make a dividend, distribution, buy back of shares (or any other return
                                         of equity) or take other corporate actions (the Corporate Action) which could
                                         result in a potential weakening of the covenant supporting the Group Fund.

 

		8.2	If the
                                         Trustee considers the Corporate Action has a materially detrimental effect on the covenant
                                         supporting the Group Fund the Trustee will take into account the Net Contribution as
                                         well as other relevant factors in deciding appropriate mitigation. Net Contribution
                                         means the Contribution less the deficit repair contributions that would have been
                                         paid to the Main Fund Section of the Group

                                         

                                         

                                         Fund pursuant to the 2013 Recovery Plan dated 27 June 2014 up to the time of the Corporate
                                         Action had the Trustee had not entered into this MoU.

 

    	 

    	 

    

		9.	BANKING
                                         REFORM REQUIREMENTS

 

		9.1	The Trustee
                                         acknowledges that the Royal Bank of Scotland Group must comply with the reforms proposed
                                         by the Independent Commission on Banking, including the changes made to the Financial
                                         Services and Markets Act 2000 (by the Banking Act 2013) and the Financial Services and
                                         Markets Act 2000 (Banking Reform) (Pensions) Regulation 2015.

 

		9.2	The Principal
                                         Employer shall, and shall procure that each participating employer shall, act reasonably
                                         and in good faith towards the Group Fund in the implementation of the changes mentioned
                                         in ‎9.1. The Trustee shall act reasonably and in good faith towards each participating
                                         employer when considering any proposal (including any apportionment proposal) relating
                                         to a participating employer which results from compliance with these reforms. In particular,
                                         the Trustee agrees to act reasonably and in good faith in considering the detriment that
                                         the Group Fund will actually suffer as a result of compliance with the reforms.

 

		10.	STAKEHOLDER
                                         ENGAGEMENT POLICY

 

On
completion of the 2015 Valuation the Principal Employer and the Trustee will discuss and agree a stakeholder engagement policy
governing how both parties will engage with each other in the running of the Group Fund. The Trustee agrees that the policy will,
among other things, afford to the Principal Employer attendance at meetings at which strategic investment issues are to be discussed
and copies of relevant papers to be made available. The manner of the Principal Employer’s attendance at meetings and the
distribution of relevant papers (including but not limited to notice, attendees and frequency of meetings) shall be as the Trustee
considers appropriate.

 

		11.	CESSATION
                                         OF MOU

 

The
MoU shall cease to apply with effect from the earlier date of the signing of or, 15 months after the effective date of the Next
Valuation.

 

		12.	AMENDMENT

 

The
Principal Employer and the Trustee may agree to amend this Memorandum of Understanding by signing an amended and restated version
of the Memorandum of Understanding incorporating all agreed amendments.

 

		13.	COUNTERPARTS

 

This
Memorandum of Understanding may be executed in any number of counterparts, all of which taken together will constitute one and
the same document and any party may enter into this Memorandum of Understanding by executing a counterpart.

	Should the Offeror notify to the Sellers’ Representative a New Schedule 4.3(a)(iv) within the above-mentioned timeframe, such New Schedule 4.3(a)(iv) shall, with effect from (and including) the date of such notice, automatically supersede Schedule 4.3(a)(iv) to the Securities Purchase Agreement as appended as of the date hereof, so that any reference to Schedule 4.3(a)(iv) to the Securities Purchase Agreement shall be construed as a reference to the New Schedule 4.3(a)(iv), which the parties to this Letter expressly acknowledge and agree.  With effect from (and including) the date of such notice, Schedule 4.3(a)(iv) to the Securities Purchase Agreement as appended as of the date hereof shall be modified, restated and replaced in its entirety by New Schedule 4.3(a)(iv), which the parties to this Letter expressly acknowledge and agree.

	13.
	EXERCISE OF THE PUT OPTION - EXECUTION OF THE SECURITIES PURCHASE AGREEMENT

		
	(a)
	If the Sellers decide to exercise the Put Option, the Sellers’ Representative shall do so on behalf of all the Sellers by notifying the Offeror and the Purchaser in writing of the Sellers’ decision between the Exercise Period Opening Date (included) and the Expiry Date (included) (the "Exercise Notice"), in the form attached to this Letter as Schedule 2.

		
	(b)
	The Exercise Notice shall specify the date (being a Business Day no sooner than the fifth (5th) Business Day and no later than the tenth (10th) Business Day after the date on which the notice was sent) on which the Securities Purchase Agreement is to be executed, unless the Offeror and the Sellers’ Representative agree in writing on another date prior to or on such date (either of such dates, the "Signing Date"), and the time and location in Paris at which the Securities Purchase Agreement is to be executed, unless otherwise agreed in writing by the Sellers’ Representative and the Offeror prior to or on the Signing Date.

		
	(c)
	In any case, subject to the sending of the Exercise Notice between the Exercise Period Opening Date (included) and the Expiry Date (included) and subject to the terms of this Letter (and, in particular, subject to the terms of Clauses 3(b), 9(b) and 12), we irrevocably undertake to procure that the Purchaser executes, and the Purchaser hereby irrevocably undertakes to execute the Securities Purchase Agreement, and we irrevocably undertake to execute the Securities Purchase Agreement for the sole purpose of Section 11.4 of the Securities Purchase Agreement, on the Signing Date, at the time and location specified in the Exercise Notice, or at such other time and/or location as may be agreed upon in writing by the Sellers’ Representative and the Offeror prior to or on the Signing Date.

-12-

		
	(d)
	We acknowledge that as of the date hereof, the Sellers accept the benefit of the Put Option without undertaking to exercise it.  Until the Sellers’ Representative’s exercise of the Put Option on behalf of all the Sellers, the Sellers will therefore not be committed to sell the Transferred Securities to the Purchaser and will not be bound by any obligation in connection with the Transaction.

		
	(e)
	In connection with the significant amount of fees and expenses incurred by the Offeror on behalf of the Purchaser and/or by the Purchaser since the beginning of our discussions for the purposes of evaluating the Transaction and preparing this Letter (together with its Schedules), the Sellers hereby undertake, individually and not jointly (conjointement mais non solidairement), to reimburse to the Purchaser (or to the Offeror or to such other Affiliate of the Offeror and within such proportions as the Purchaser and the Offeror may jointly notify to the Sellers’ Representative for such purpose), within thirty (30) calendar days of, where applicable, the Expiry Date or the Signing Date, those fees and expenses, in a maximum aggregate amount of five millions Euros (€5,000,000) and provided that the relevant supporting documents are provided to the Sellers’ Representative, each of them within the limit of its Portion (as such term is defined below) of such fees and expenses, (A) should the Sellers’ Representative (on behalf of all the Sellers): (i) refuse any proposition by the Offeror to postpone the date mentioned in Clause 1(a)(ii) pursuant to Clause 1(b) by at least one (1) month, where the Exercise Period Opening Date may not occur before March 31, 2016 for a reason beyond the Offeror’s control; or (ii) decide, as is the Sellers’ right, not to exercise the Put Option on behalf of all the Sellers between the Exercise Period Opening Date (included) and the Expiry Date (included), provided that the Offeror has complied with all of its material obligations hereunder, or (B) should any Seller or Kepler M2 not proceed with the execution of the Securities Purchase Agreement on the Signing Date, in the event that the Put Option is exercised by the Sellers’ Representative on behalf of all the Sellers between the Exercise Period Opening Date (included) and the Expiry Date (included).  For the avoidance of doubt, it is expressly specified that in the event that the Put Option and this Letter terminate at the date mentioned in Clause 1(a)(ii) (as postponed pursuant to (A)(i) above, as the case may be) in accordance with Clause 1(b) above prior to the occurrence of the Exercise Period Opening Date for any reason beyond the Sellers’ control, the Sellers shall not be liable for any reimbursement of fees and expenses whatsoever.

For the purpose of the preceding paragraph, "Portion", when used with respect to a Seller, shall mean the fraction having for numerator, the portion of the Adjusted Enterprise Value (as such term is defined below) which would have been allocable to the Transferred Securities (other than the Mezzanine Bonds, if any) owned by such Seller by application of the provisions of Section 2.9 of the Securities Purchase Agreement (i) as if the Final Price was equal to the Enterprise Value (without any net cash or working capital adjustment), (ii) as of, where applicable, the Expiry Date or the Signing Date and (iii) by using the foreign exchange rate of Euros converted into US Dollars as of, where applicable, the Expiry Date or the Signing Date, as determined on the basis of the Euro foreign exchange reference rate of the European Central Bank as updated by 3 p.m. C.E.T. on, where applicable, the Expiry Date or the Signing Date, and for denominator, the Adjusted Enterprise Value.
For the purpose of the preceding paragraph, "Adjusted Enterprise Value" shall mean the Enterprise Value less the value as of, where applicable, the Expiry Date or the Signing Date, of the Mezzanine Debt, as converted from Euros into US Dollars by using the foreign exchange rate of Euros converted into US Dollars as of, where applicable, the Expiry Date or the Signing Date, as determined on the basis of the Euro foreign exchange reference rate of the European Central Bank as updated by 3 p.m. C.E.T. on, where applicable, the Expiry Date or the Signing Date.
The parties to this Letter expressly acknowledge and agree that notwithstanding anything to the contrary in this Letter, the provisions of this Clause 13(e) shall survive any termination of 

-13-

this Letter, (A) should the Sellers’ Representative (on behalf of all the Sellers): (i) refuse any proposition by the Offeror to postpone the date mentioned in Clause 1(a)(ii) pursuant to Clause 1(b) by at least one (1) month, where the Exercise Period Opening Date may not occur before March 31, 2016 for a reason beyond the Offeror’s control; or (ii) decide, as is the Sellers’ right, not to exercise the Put Option on behalf of all the Sellers between the Exercise Period Opening Date (included) and the Expiry Date (included), provided that the Offeror has complied with all of its material obligations hereunder, or (B) should any Seller or Kepler M2 not proceed with the execution of the Securities Purchase Agreement on the Signing Date, in the event that the Put Option is exercised by the Sellers’ Representative on behalf of all the Sellers between the Exercise Period Opening Date (included) and the Expiry Date (included).
		
	(f)
	Subject to the provisions of Clause 13(e) above, each party to this Letter shall be responsible for payment of all fees and costs incurred by it or on its behalf in connection with the negotiation, preparation and signing of this Letter (and its Schedules) and the consummation of the transactions contemplated hereby, including the fees and disbursements of its financial advisors, accountants and attorneys.

		
	(g)
	In any case, each party to this Letter agrees to be bound by the specific commitments expressly made by it under this Letter, as the case may be.

		
	(h)
	Subject to the sending by the Sellers’ Representative of the Exercise Notice between the Exercise Period Opening Date (included) and the Expiry Date (included) and subject to the terms of this Letter (and, in particular, subject to the terms of Clauses 3(b), 9(b) and 12), Kepler M2 hereby irrevocably undertakes to execute, and the Sellers undertake to procure that Kepler M2 executes, the Securities Purchase Agreement for the sole purpose of Sections 5.1 to 5.5, 5.9 and 5.12 of the Securities Purchase Agreement on the Signing Date, at the time and location specified in the Exercise Notice, or at such other time and/or location as may be agreed upon in writing by the Sellers’ Representative and the Offeror prior to or on the Signing Date.

Re:    Project Tahoe - Exercise Notice
Dear Sirs,
Reference is made to the offer letter dated December 7, 2015 entered into by and between the Offeror, the Purchaser, Kepler M2 and the Sellers (the "Put Option Agreement").  Capitalized terms in this letter (the "Exercise Notice") shall, unless otherwise defined herein, have the meanings ascribed to them in the Put Option Agreement.
In accordance with the provisions of Clauses 1, 9, 11, 12, 13, 19 and 22 of the Put Option Agreement, we hereby:
		
	(i)
	Notify the Offeror and the Purchaser of the Sellers’ decision to exercise the Put Option;

		
	(ii)
	Confirm to the Offeror and the Purchaser that:

		
	•
	the IP Agreement has been duly executed by Kepler and France Brevets and a certified copy of the IP Agreement duly executed by Kepler and France Brevets has been provided to the Offeror and the Purchaser, in both cases on or prior to the date hereof;

		
	•
	the Information and Consultation Process has been fully completed and evidence thereof has been provided to the Offeror and the Purchaser, in both cases on or prior to the date hereof;

		
	•
	the provisions of paragraphs (a) and (b) of Clause 5 of the Put Option Agreement have been definitively complied with and evidence thereof has been provided to the Offeror and the Purchaser, in both cases on or prior to the date hereof;

		
	•
	as of the date hereof, save for what has been set forth in the Securities Purchase Agreement or notified pursuant to Clause 9(a) of the Put Option Agreement as constituting or being likely to constitute a Material Adverse Change, no circumstance, event or fact has occurred since the Reference Date that constitutes or would be likely to constitute a Material Adverse Change; 

		
	•
	pursuant to Clause 9(a)(ii) of the Put Option Agreement, the Offeror and the Purchaser will be promptly notified of the occurrence (or non-occurrence) between the date hereof (included) and the actual date of execution of the Securities Purchase Agreement (included) of any event, the occurrence (or non-occurrence) of which constitutes or would be likely to constitute a Material Adverse Change;

		
	•
	as of the date hereof, no Permitted Transfer has been completed in breach of Clause 10 prior to or on the Signing Date;

		
	•
	pursuant to Clause 10, no Permitted Transfer will be completed from the date hereof (included); and

		
	•
	pursuant to Clause 11, should the Offeror notify to the Sellers’ Representative a New Schedule 4.3(a)(iv) within two (2) Business Days of the receipt of this Exercise Notice, such New Schedule 4.3(a)(iv) will, with effect from (and including) the date of such notice, automatically supersede Schedule 4.3(a)(iv) to the Securities Purchase Agreement as appended as of the date of the Put Option Agreement, so that any reference to Schedule 4.3(a)(iv) to the Securities Purchase Agreement will be construed as a reference to the New Schedule 4.3(a)(iv).  With effect from (and including) the date of such notice, Schedule 4.3(a)(iv) to the Securities Purchase Agreement as appended as of the date of the Put Option Agreement will be modified, restated and replaced in its entirety by New Schedule 4.3(a)(iv) and therefore we confirm that the New Schedule 4.3(a)(iv) will be appended to the execution version of the Securities Purchase Agreement on the Signing Date.

		
	(iii)
	Specify that the Securities Purchase Agreement is to be executed on [•], 2016, unless the Sellers’ Representative and the Offeror agree in writing on another date prior to or on such date, and at [•] [a.m./p.m.] (Paris time), at the offices of Shearman & Sterling LLP, 114, avenue des Champs-Elysées, 75008 Paris (France), unless otherwise agreed between the Sellers’ Representative and the Offeror in writing prior to or on the Signing Date.

Pursuant to Clause 22 of the Put Option Agreement, this Exercise Notice and any contractual or non-contractual obligation arising out of or in connection with this Exercise Notice shall be governed by, and construed in accordance with, French law.  All disputes arising out of or in connection with this

Exercise Notice (including without limitation with respect to the existence, validity, performance, termination and interpretation of this Exercise Notice and any non-contractual obligation arising out of or in connection with this Exercise Notice) shall be submitted to the exclusive jurisdiction of the Commercial Court of Paris.
