(F) where reasonably requested by a party, and insofar as permitted by the Relevant Authority, the other party shall make available appropriate representatives for meetings and calls with any Relevant Authority in connection with the obtaining of any Clearances,

17

6.3 Shell shall be entitled, with the consent of the Panel, to implement the Acquisition by way of the Offer rather than the Scheme (such election being a “Switch”) if:

(C) the board of directors of BG withdraws its unanimous and unconditional recommendation of the Scheme.

6.4 In the event of any Agreed Switch:

(A) the Acceptance Condition shall be set at 90 per cent. (or such lesser percentage as may be agreed between the parties in writing after, to the extent necessary, consultation with the Panel, being in any case more than 50 per cent. of the BG Shares to which the Offer relates);

(B) Shell shall not take any action which would cause the Offer not to proceed, to lapse or to be withdrawn in each case for non-fulfilment of the Acceptance Condition prior to the 60^th day after publication of the Offer Document and Shell shall ensure that the Offer remains open for acceptances until such time;

(C) Shell shall ensure that the only pre-conditions of the Offer shall be the Pre-Conditions and that the only conditions of the Offer shall be the Conditions (subject to replacing the Scheme Conditions with the Acceptance Condition referred to in Clause 6.4(A)) (unless the parties agree otherwise in writing); and

(D) Shell shall keep BG informed, on a regular basis and in any event within two Business Days following receipt of a written request from BG, of the number of holders of BG Shares that have validly returned their acceptance or withdrawal forms or incorrectly completed their withdrawal or acceptance forms and the identity of such shareholders.

6.5 In the event of any Agreed Switch:

(A) the parties agree that all provisions of this Agreement relating to the Scheme and its implementation shall apply to the Offer or its implementation mutatis mutandis;

(B) Shell’s obligations under Clause 5.2 shall apply to the Offer Document as if references in such Clause to the Shell Circular were to the Shell Circular and the Offer Document; and

(C) BG’s obligations under Clause 5.4 shall apply to the Offer Document as if references in such Clause to the Shell Circular were to the Shell Circular and the Offer Document.

18

6.6 In the event that the board of directors of BG no longer unconditionally and unanimously recommends the Scheme (or Offer, as the case may be) both parties’ obligations under this Agreement shall terminate (including, for the avoidance of doubt, Shell’s obligation to make any Break Payment, unless a Break Payment Event has occurred prior to such change of recommendation) except for:

(A) BG’s obligation to provide Shell with all reasonable information, assistance and access in a timely manner to the extent required in order to allow Shell to make and / or diligently pursue any filings with any Relevant Authority as are necessary in connection with the Clearances pursuant to Clause 3.3; and

(B) Clauses 15 to 26 so far as they relate to such obligation referred to in (A) above.

7. Conduct of business

Pending the Effective Date, Shell shall not (except (i) with BG’s prior written consent, (ii) where required by law or regulation or (iii) to the extent the relevant matter is expressly permitted or contemplated by this Agreement), and shall procure that no member of the Shell Group agrees, resolves, commits or announces publicly any agreement or intention to:

(A) other than in the ordinary course of business and consistent with past practice (including, without limitation, the granting of options or awards in respect of shares to employees in the normal and ordinary course and in accordance with the Shell Group’s employee incentive plans and the issuance of shares necessary to satisfy such options or awards vesting or due to be settled under such plans):

(i) allot or issue any Shell shares or any securities convertible into Shell shares; or

(ii) grant any option over or right to subscribe for any such shares or any such securities referred to in (i) above

in each case that are allotted, issued or granted at less than the fair market value of the relevant security on the date of allotment, issuance or grant; or

(B) split, combine or reclassify any of its shares or amend its memorandum or articles of association, in each case, in any manner that would have an adverse impact on the value of the New Shell Shares.

8. Employees and share plans

8.1 The parties agree that the provisions of Schedule 1 (BG Share Plans) shall apply.

8.2 BG and Shell agree that if the Acquisition is implemented by way of the Scheme, the timetable for its implementation shall be fixed so as to enable options and awards under the relevant BG Share Plans which provide for exercise and / or vesting upon the sanction of the Scheme by the Court to be exercised or vest in sufficient time to enable the resulting BG Shares to be bound by the Scheme on the same terms as BG Shares held by BG shareholders.

19

9. Tax matters

9.1 Shell warrants to BG that:

(A) in agreeing the Preliminary Settlement Agreement with the DRS, Shell has disclosed completely and correctly all relevant facts and circumstances to the DRS and there are no written or unwritten agreements between the DRS and Shell (other than the Preliminary Settlement Agreement), and there are no unilateral commitments by either Shell or the DRS to the other (other than under the Preliminary Settlement Agreement), that may in any way affect the validity of the Preliminary Settlement Agreement or may change, restrict or otherwise affect the points agreed therein; and

(B) the Preliminary Settlement Agreement has been executed by an authorised representative of Shell, and to the best of Shell’s knowledge, by an authorised representative of the DRS.

9.2 Shell agrees that it will use all reasonable endeavours to reach a binding final settlement agreement with the DRS, reflecting, amongst other things, the matters set out in the Preliminary Settlement Agreement (the “Final Settlement Agreement”).

9.3 Without prejudice to Clause 9.2:

(A) Shell shall provide each draft of the Final Settlement Agreement before it is submitted to the DRS to BG at such time as will allow BG a reasonable opportunity to provide comments on it before the draft is submitted or sent;

(B) Shell shall have regard in good faith to comments promptly provided by BG on the draft copies provided pursuant to Clause 9.3(A);

10. Directors’ and officers’ insurance

10.1 If and to the extent such obligations are permitted by law, for six years after the Effective Date, Shell shall procure that the members of the BG Group honour and fulfil their respective obligations (if any) existing as at the date of this Agreement to indemnify their respective directors and officers and to advance expenses, in each case with respect to matters existing or occurring at or prior to the Effective Date.

10.2 With effect from completion of the Acquisition, Shell shall, to the extent such cover is available on reasonable commercial terms, procure the provision of directors’ and officers’ liability insurance cover for both current and former directors and officers of the BG Group, including directors and officers who retire or whose employment is terminated as a result of the Acquisition, for acts and omissions up to and including the Effective Date, in the form of runoff cover for a period of six years following the Effective Date. Such insurance cover shall be with reputable insurers and provide cover, in terms of amount and breadth, at least as much as that provided under the BG Group’s directors’ and officers’ liability insurance as at the date of this Agreement.

11. Break Payment

11.1 By way of compensation for any loss suffered by BG in connection with the preparation and negotiation of the Acquisition, this Agreement and any other document relating to the Acquisition, subject to Clause 11.2, Shell shall pay, or shall procure the payment by a member of the Shell Group of, the Break Payment to BG in the event that, following the publication of the Announcement in accordance with Clause 2.1:

(A) on or prior to the Long Stop Date, the board of directors of Shell:

(i) withdraws the Shell Board Recommendation;

(ii) publicly announces its intention not to include the Shell Board Recommendation in the Shell Circular when it is sent to Shell shareholders or its intention not to send the Shell Circular to Shell shareholders; or

(iii) does not include the Shell Board Recommendation in the Shell Circular when it is sent to Shell shareholders,

and, in any such case, BG or Shell exercises its right to terminate this Agreement pursuant to Clause 13.1(D);

21

(B) on or prior to the Long Stop Date, Shell invokes (and is permitted by the Panel to invoke) any Pre-Condition and / or any Regulatory Condition; or

(C) on the Long Stop Date, any Pre-Condition and / or any Regulatory Condition has not been satisfied or waived by Shell,

(each a “Break Payment Event”).

11.2 No Break Payment shall be payable if:

(A) at the time the relevant Break Payment Event occurs, this Agreement has been terminated pursuant to Clause 13.1(A), (B), (C), (E), (F) or (G), save where:

(i) this Agreement has terminated pursuant to Clause 13.1(E) as a result of any Pre-Condition or Regulatory Condition: (a) being invoked by Shell (b) becoming incapable of satisfaction by the Long Stop Date and Shell stating that it will not be waived or (c) not being capable of being waived and becoming incapable of satisfaction by the Long Stop Date; or

(ii) this Agreement has terminated pursuant to Clause 13.1(G) and the Scheme (or the Offer as the case may be) has been withdrawn or lapsed as a result of a Pre-Condition or Regulatory Condition being:  (a) invoked by Shell; (b) becoming incapable of satisfaction by the Long Stop Date and Shell stating that it will not be waived or (c) not being capable of being waived and becoming incapable of satisfaction by the Long Stop Date;

(B) the Break Payment Event has been caused to a material extent by BG’s breach of its obligations under Clauses 3.1 to 3.6 or Clause 5.4 of this Agreement, provided that Shell shall have notified BG in writing promptly upon becoming aware of any such failure and BG shall not have remedied any such failure within 15 days of receipt of such notice or, if earlier, in sufficient time for Shell to reasonably meet any regulatory or legal deadline; or

(C) at the time the relevant Break Payment Event occurs, Shell has already effected a Switch in accordance with Clauses 6.3(B) or 6.3(C).

11.3 Subject to Clause 11.4, Shell shall pay or procure the payment of the Break Payment to BG within 10 Business Days of the occurrence of the Break Payment Event.

11.4 The parties anticipate, and shall take the position and use all reasonable endeavours to ensure that it is accepted for the relevant tax purposes, that the Break Payment is outside the scope of VAT and is not treated for VAT purposes as consideration for a taxable supply.  If, however, the Break Payment is treated by any tax authority in whole or part as the consideration for a taxable supply: (i) BG shall provide Shell with a valid VAT invoice in respect of that supply; and (ii) if BG (or the representative member of the VAT group of which BG is a member) is liable to account for VAT in respect of that supply, Shell shall pay to BG (in addition to any other consideration for that supply) an amount equal to such VAT.  Any such additional amounts in respect of VAT shall be paid no later than the date falling 10 days before the date on which BG (or the representative member of the VAT group of which BG is a member) is liable to account for such VAT (the “Due Date”) or, if later, the date falling five days after BG has notified Shell in writing of the Due Date.

22

11.5 Payment shall be made in immediately available funds (without any deduction or withholding, save only as requested by law, and without regard to any lien, right of set-off, counterclaim or otherwise) to such bank account as may be notified to Shell by BG for such purpose.

11.6 In the event that the Break Payment is paid in accordance with this Clause 11 and this Agreement terminates in accordance with Clause 13.1(D), except with respect to fraud, BG’s right to receive the Break Payment (plus any additional amounts in respect of VAT under Clause 11.4) shall be the sole and exclusive remedy of BG against Shell for any and all losses and damages suffered in connection with this Agreement and the transactions contemplated by this Agreement. In no event shall Shell be required to pay the Break Payment more than once or pay more than one Break Payment.

12. Code and the Listing Rules

12.1 Nothing in this Agreement shall in any way limit the parties’ obligations under the Code, and any uncontested rulings of the Panel as to the application of the Code in conflict with the terms of this Agreement shall take precedence over such terms.

12.2 Nothing in this Agreement shall oblige:

(A) BG to take any action which the Panel determines would not be permitted by Rule 21.2 of the Code;

(B) BG or the directors of BG to recommend an Offer or a Scheme proposed by Shell or any member of the Shell Group; or

(C) Shell to pay any amount over that which is permitted to be paid without the prior approval of its shareholders pursuant to LR 10.2.7R of the Listing Rules.

(B) upon service of written notice by Shell to BG, if the board of directors of BG withdraws or adversely modifies its unanimous and unconditional recommendation of the Scheme (or the Offer, as the case may be);

(C) upon service of written notice by Shell to BG, if the Acquisition is being implemented by way of the Scheme and:

23

(i) the Court Meeting is not held on or before the 22^nd day after the expected date of such hearing as set out in the Scheme Document (or such later date as may be agreed in writing between the parties with the consent of the Panel and the approval of the Court (if such approval is required)); or

(ii) the Sanction Hearing is not held on or before the 22^nd day after the expected date of such hearing as set out in the Scheme Document (or such later date as may be agreed in writing between the parties with the consent of the Panel and the approval of the Court (if such approval is required));

(D) upon service of written notice by Shell to BG, following a Break Payment Event, or, upon service of written notice by BG to Shell, following a Break Payment Event under any of Clauses 11.1(A)(i), (ii) or (iii);

(E) upon service of written notice by Shell to BG (without prejudice to Clause 11) prior to the Long Stop Date stating that either (i) any Pre-Condition or Condition which has not been waived is (or has become) incapable of satisfaction by the Long Stop Date and, notwithstanding that it has the right to waive such Pre-Condition or Condition, Shell will not do so; or (ii) any Pre-Condition or Condition which is incapable of waiver has become incapable of satisfaction by the Long Stop Date, in each case in circumstances where the invocation of the relevant Pre-Condition or Condition (or confirmation that the Pre-Condition or Condition is incapable of satisfaction, as appropriate) is permitted by the Panel;

(F) upon service of written notice by Shell to BG, if a Competing Proposal is (i) recommended by the board of directors of BG or (ii) completes, becomes effective or is declared or becomes unconditional in all respects;

(G) if the Scheme (or the Offer as the case may be) is withdrawn or lapses in accordance with its terms prior to the Long Stop Date and with the permission of the Panel (other than: (i) where such lapse or withdrawal is as a result of the exercise of Shell’s right to effect a Switch; or (ii) it is otherwise to be followed within five Business Days by an announcement under Rule 2.7 of the Code made by Shell or a person acting in concert with Shell to implement the Acquisition by a different offer or scheme on substantially the same or improved terms); or

(H) if the Effective Date has not occurred by the Long Stop Date.

13.2 Termination of this Agreement shall be without prejudice to the rights of any of the parties which have arisen at or prior to termination. For the avoidance of doubt, if the Agreement is terminated pursuant to Clause 13.1, Shell will remain obliged to pay the Break Payment to the extent that it had become due and payable at or prior to any such termination (subject to the provisions of this Agreement then in force) on the occurrence of the Break Payment Event (together with any additional amounts in respect of VAT under Clause 11.4).

24

13.3 The whole of this Clause 13, Clause 10 (but only in circumstances where this Agreement is terminated on or after the Effective Date), and Clauses 15 to 26 (inclusive) shall survive termination of this Agreement.

SCHEDULE 1 BG Share Plans

BG and Shell agree that the following provisions will, where appropriate, apply to the BG Share Plans and certain other employee incentive arrangements.

1. General Employee Share Plan matters

1.1 Shell agrees that BG may amend the rules of any of the BG Share Plans in relation to the time at which options may be exercised or awards vest if, in the opinion of the BG directors or the BG Remuneration Committee, such amendments are necessary or desirable to implement the Scheme, facilitate the administration of the BG Share Plans or to obtain or maintain favourable tax treatment for participants in such plans or any member of the BG Group. BG agrees that in advance of making any such amendment, BG shall notify Shell that such amendment is being considered by the BG directors or the BG Remuneration Committee, as appropriate, and BG agrees that Shell shall be entitled to make representations to the relevant body, which the relevant body shall consider prior to making any such amendment. Shell acknowledges that neither the BG directors nor the BG Remuneration Committee shall be bound to act in accordance with Shell’s representations.

1.2 If BG considers it appropriate for tax, securities law or administrative reasons, in order to ensure that employees in all jurisdictions are treated so far as practicable equally, it may propose that holders of options and awards who are not resident in the United Kingdom receive a cash sum equal to the latent profit in their option or award being (i) in the case of an option, the difference between the exercise price per share (if any) and the value of the Offer Consideration at the time of the Scheme Order or the Unconditional Date (as the case may be) multiplied by the number of BG Shares in respect of which the option is exercised or (ii) in the case of an award, the value of the Offer Consideration at the time of the Scheme Order or the Unconditional Date (as the case may be) multiplied by the number of BG Shares in respect of which the award vests.  The parties will then discuss in good faith whether that is appropriate and, if they so agree, subject to any restriction under law, the Code or other regulation, the proposals made by BG and the Rule 15 proposals to be made by Shell will be adjusted accordingly in that jurisdiction.

2. Long-Term Incentive Plan

2.1 References in this Schedule 1 to awards outstanding under the LTIP include awards outstanding and granted under the Deferred Bonus Plan and the Voluntary Bonus Deferral Plan.

2.2 Shell acknowledges that the extent to which awards outstanding under the LTIP vest at the date of the Scheme Order (or the Unconditional Date, as the case may be) in connection with the Acquisition is to be determined solely by the BG Remuneration Committee in accordance with the rules of the LTIP.

2.3 Shell acknowledges that BG grants awards on and subject to the rules of the LTIP on an annual basis in May. Shell acknowledges that BG proposes to grant awards on and subject to the rules of the LTIP in or around May 2015 with a total aggregate market value of approximately £70 million (“2015 Awards”) of which approximately £33 million will relate to performance based awards and approximately £37 million to non-performance based awards.

2.4 Shell acknowledges that BG may decide to grant additional awards under the LTIP in accordance with its normal practice and in a manner and on a timetable consistent with historic practice, including making (i) additional ad hoc awards for recruitment and other similar purposes provided that such awards are not over shares with a value of more than £3 million measured at their date of grant; (ii) an annual grant in May 2016 if the Effective Date has not occurred by that time which shall be on terms which are consistent with the terms for the 2015 Awards and shall not be over shares with an aggregate market value greater than for those 2015 Awards; and (iii) deferred bonus awards and voluntary bonus deferral awards in respect of any bonuses payable in respect of BG’s financial year ending 31 December 2015 in a manner and on a timetable consistent with historic practice.

3. Deferred Bonus Awards under the LTIP

Shell acknowledges that BG intends to grant awards on and subject to the rules of the Deferred Bonus Plan over an aggregate number not exceeding 34,333 BG Shares to two individuals who are “restricted persons” for the purposes of the UKLA Model Code as soon as BG is no longer in a prohibited period.

4. Sharesave

4.1 Unless paragraph 4.2 applies, Shell agrees to offer participants in the Sharesave the opportunity following the date of the Scheme Order (or the Unconditional Date, as the case may be) to release all or any of their Sharesave options over BG Shares (“Original Options”) in consideration for the grant of an equivalent option over Shell B Shares (“Replacement Option”) on and subject to the rules of the Sharesave and any approvals that may be required of HMRC (“Option Rollover”). Shell and BG will seek to agree with HMRC that the ratios on the basis of which an Original Option shall be exchanged for a Replacement Option shall be calculated by reference to the respective market values attributable to a Shell B Share and a BG Share by the value of the Offer Consideration measured at the date of the Scheme Order (or the Unconditional Date, as the case may be) or at such other time as is agreed by Shell and BG and approved by HMRC.

4.2 This paragraph 4.2 applies if Shell is for whatever reason unable to grant a Replacement Option which satisfies the requirements of Schedule 3 to the Income Tax (Earnings and ▇▇▇▇▇▇▇▇) ▇▇▇ ▇▇▇▇ and the relevant Original Option becomes exercisable following the date of the Scheme Order (or the Unconditional Date, as the case may be), over less than the full number of BG Shares that could otherwise be acquired on maturity of the related savings contracts. Shell agrees that it will make (or procure that BG will make) within one month of the normal maturity date or any earlier lapse date after the cessation of employment a one off cash payment to the holders of those Original Options which were granted prior to the date of the Announcement and who (A) exercise those options at any time during the 6 month period following the date of the Scheme Order (or the Unconditional Date, as the case may be) and (B) either (i) are still at the normal time of maturity for the related savings contract employed by a member of the Shell Group or (ii) have ceased employment in circumstances where under Rules 10.2, 10.3 or 12 of the Sharesave their option remains exercisable. The cash payment will be of an amount equal, on a net of tax basis, to the additional profit which the participants would have received had they been able to exercise their options over the additional number of BG Shares which would otherwise have been available (i) on the maturity of their savings contracts; or (if earlier) (ii) the lapse date of the options after the cessation of employment and had then been able to accept the Scheme or Offer (as the case may be) in respect of that additional number of BG Shares. For the avoidance of doubt, any such cash payment would be subject to deductions for income tax and employee’s social security contributions.

4.3 Shell acknowledges that BG may decide to grant options under the Sharesave prior to the date of the Scheme Order (or the Unconditional Date, as the case may be), in accordance with its normal practice and timetable and in a manner consistent with historic practice.

5. SIP and Global Partnership Plan

5.1 Shell acknowledges that prior to the date of the Scheme Order (or the Unconditional Date, as the case may be), participants in the SIP and the Global Partnership Plan will continue to accumulate savings from their salary over six month accumulation periods and that those savings will (to the extent an accumulation period is completed prior to the date of the Scheme Order (or the Unconditional Date, as the case may be)) be used to purchase BG Shares in accordance with the rules of those plans and that BG may award (i) in the case of the SIP, free BG Shares (known as flex shares) for no consideration and (ii) in the case of the Global Partnership Plan, matching BG Shares for no consideration, in each case in accordance with BG’s normal practice and timetable and in a manner consistent with historic practice.

5.2 Shell and BG agree that BG shall retain the trust established pursuant to the SIP for at least five years following the date of the Scheme Order (or the Unconditional Date, as the case may be) as a vehicle available to participants in the SIP in which to hold any Shell B Shares they acquire under the Acquisition in exchange for the BG Shares they hold under the SIP so as to optimise the UK tax favourable treatment available to participants.

6. Articles of Association

BG and Shell agree that shareholder approval will be sought for an amendment to the articles of association of BG so that any BG Shares transferred or issued after the Scheme Record Time pursuant to the exercise of options or vesting of awards under the BG Share Plans will be compulsorily acquired by Shell on the same terms as were available to other BG Shareholders under the Acquisition. Shell agrees that it is the commercial intention of the parties that, so far as practicable, the Shell B Shares comprised in the consideration to be provided under the amended terms of the articles of association will be issued by Shell. Shell agrees that it will use its reasonable endeavours to include in the Final Settlement Agreement provisions enabling Shell to issue Shell B Shares under such amended terms.  If for any reason it is not practicable to issue Shell B Shares then Shell will procure the transfer of such shares.

7. The Trust

As at 31 December 2014, the Trust held 2,830,140 unallocated BG Shares. Subject always to the BG Group’s ability to make recommendations to the trustee of the Trust to use the unallocated BG Shares to satisfy awards vesting or options being exercised in the normal course prior to the Effective Date, the parties agree that the trustee of the Trust will be requested to agree to satisfy certain options and awards vesting or becoming exercisable as a consequence of the Acquisition, using any unallocated BG Shares in priority to BG issuing BG Shares to satisfy such options and awards.

8. Communications

BG and Shell shall co-operate with each other to prepare, in a form to be agreed between BG and Shell, communications (or, if applicable, multiple series of communications) to each of the participants in the BG Share Plans to enable Shell to satisfy its obligations under Rule 15 of the Code, and to send, or arrange for the sending of such communications (or series of communications, as the case may be) to participants at the appropriate time(s) (such time(s) to be agreed between the parties).

9. Annual Incentive and other bonus schemes

9.1 Subject to paragraphs 9.2 and 9.3 below, Shell acknowledges that the BG Group operates annual incentive schemes for its group, management, and energy trading employees under which bonuses are awarded subject to corporate, financial, business unit and personal performance conditions and that the BG Group shall continue to operate these arrangements for the performance periods constituting the financial years ending 31 December 2015 and 31 December 2016 (if the Effective Date has not occurred by that time) in accordance with its normal practice and in a manner consistent with historic practice.

9.2 Shell agrees that if the Effective Date occurs before the end of a financial year, members of the BG Group may decide in accordance with the terms of the relevant incentive scheme to measure the extent to which performance measures for the relevant financial year have been satisfied as at the Effective Date and to determine and pay bonus awards for that period pro-rated to reflect the number of days in the relevant year that have been worked up to the Effective Date. If members of the BG Group do make such a pro-rated payment to employees of the BG Group, Shell agrees that employees shall continue to participate in the same or an equivalent incentive scheme in respect of the remainder of the relevant financial year and that it will make, or procure the BG Group to make, bonus awards to such employees to be assessed on the basis of their individual performance for that period (for these purposes with an appropriate mapping to the established BG annual performance rating system) with an assumed on target business performance.

9.3 Shell agrees that if the Effective Date occurs before the end of a financial year, and if members of the BG Group decide in accordance with the terms of the relevant incentive scheme that they will not measure the extent to which performance measures for the relevant financial year have been satisfied as at the Effective Date, then the relevant incentive scheme will continue to be operated in respect of the financial year and that it will make, or procure the BG Group to make, bonus awards to eligible employees to be assessed on the basis of each eligible employee’s individual performance during the relevant financial year (for these purposes with an appropriate mapping to the established BG annual performance rating system) with an assumed on target business performance.

10. Redundancy arrangements

Shell agrees that if any employee of the BG Group (an “Employee”) has their employment terminated during the period that is 12 months after the Effective Date (other than by reason of their gross misconduct or for poor performance reasons) Shell will provide, or procure that a member of the Shell Group will provide, termination benefits (in addition to contractual notice periods and any relevant statutory payments) to each Employee in accordance with terms that mirror the redundancy termination benefits most recently provided to employees of the BG Group in the country in which the relevant Employee is based prior to the Effective Date.

11. Retention arrangements

Shell and BG will consult prior to the Effective Date with a view to agreeing the implementation of cash-based retention arrangements for employees of the BG Group whom BG considers critical to achieving the successful closure of the Acquisition or business continuity throughout the period up to the Effective Date. As part of such consultation Shell and BG will in good faith seek to agree a total budget for such arrangements.  BG will provide sufficient information to Shell in order for Shell to monitor the allocation of any agreed budget.

12. Employment Matters

Shell agrees that, for at least the 12 month period following the Effective Date, in respect of each employee of the BG Group immediately prior to the Effective Date who remains in employment within the Shell Group, it will maintain their base salary and pension benefits at the level existing immediately before the Effective Date unless otherwise agreed with the relevant employee.

Shell’s acknowledgements in paragraphs 2.3, 2.4, 3, 4.3, 5.1 and 9.1 of this Schedule 1 do not impose any contractual restrictions or obligations on the BG Group or their boards of directors.
