and the Rolled Forward Amount and the Rolled Forward Surplus Amount shall then be zero;

(B) a negative amount and more than $10,000,000, then NADL shall receive from Rosneft an amount equal to the Aggregate Surplus within 10 Business Days following receipt of the notice from NADL under Clause 3.4 and the Rolled Forward Amount and the Rolled Forward Surplus Amount shall then each be zero;

(C) a negative amount and less than or equal to US$10,000,000, then the Rolled Forward Amount shall then be equal to the modulus of the Aggregate Surplus; or

(D) a positive amount and less than or equal to US$10,000,000, then no true-up is required at that time and the Rolled Forward Surplus Amount shall then be an amount equal to the Aggregate Surplus.

3.7 At the time of the termination or expiry of the last of the Offshore Drilling Contracts and outstanding Additional Drilling Contracts to terminate or expire:

(A) if there is a Rolled Forward Amount, Rosneft and NADL shall discuss an efficient mechanism for dealing with the remaining Rolled Forward Amount and, failing such agreement, Rosneft shall, either:

(i) on the Settlement Date immediately following such termination or expiry, elect to waive its dividend rights and Clause 16.9(B) shall apply; or

(ii) pay such amount to NADL within 10 Business Days following the Settlement Date immediately following such termination or expiry provided that if such amount is subject to Russian withholding tax, Rosneft shall gross up the remaining Rolled Forward Amount in such a way that after deducting Russian withholding tax from the grossed up Rolled Forward Amount NADL receives an amount equal to the Rolled Forward Amount less an amount equal to 50% (fifty per cent.) of the tax being withheld; and

(B) if there is a Rolled Forward Surplus Amount, within 10 Business Days following the Settlement Date immediately following such termination or expiry, NADL shall issue to Rosneft such number of common shares of par value US$5 each in the share capital of NADL (rounded up to the nearest whole number of shares) as equals A/B where:

A =     the Rolled Forward Surplus Amount; and

B =     US$9.25 per share,

and the Rolled Forward Surplus Amount shall then be zero.

3.8 Any shares issued pursuant to Clause 3.6 or 3.7 shall be credited as fully paid, with the same rights and ranking pari passu in all respects with the existing fully paid common shares of par value US$5 each in the share capital of NADL. NADL shall issue any shares issued pursuant to Clause 3.6 or 3.7 free from all Encumbrances and from all other rights exercisable by or claims by third parties, together with all rights attached or accruing to them at the time of issue. NADL shall procure that all rights of pre-emption over any of the shares issued pursuant to Clause 3.6 or 3.7 conferred by the constitutional documents of NADL, by applicable law or in any other way are waived prior to their issue.

3.9 On each issue of Contract Shares or fully paid common shares of par value US$5 each in the share capital of NADL under Clause 3.6 or 3.7, NADL shall deliver a share certificate for the relevant Contract Shares or fully paid common shares of par value US$5 each in the share capital of NADL in the name of Rosneft.

3.10 Any Rolled Forward Amount or Rolled Forward Surplus Amount shall increase by an amount equal to LIBOR plus 4% (four per cent.), which shall accrue from day to day and shall form part of the Rolled Forward Amount or Rolled Forward Surplus Amount (as the case may be).

3.11 If, prior to the Acceptance Date in respect of an Offshore Drilling Contract, Rosneft and NADL agree that the amount or timing of the Actual Drilling Revenue in respect of all Settlement Periods estimated to be earned from that Offshore Drilling Contract over the term of that Offshore Drilling Contract is different from that set out in Part C of Schedule 10 (Offshore Drilling Contracts), the parties shall make corresponding adjustments to the amounts set out in column 10 of Part A of Schedule 10 (Offshore Drilling Contracts) and / or column 2 of Part B of Schedule 10 (Offshore Drilling Contracts), and Schedule 10 (Offshore Drilling Contracts) and the number of Contract Shares to be issued pursuant to Clause 3.2 shall both be adjusted accordingly. The adjustments to Schedule 10 (Offshore Drilling Contracts) and to the Estimated Drilling Revenue pursuant to this Clause shall only be made in respect of an Offshore Drilling Contract if agreed by Rosneft and NADL prior to the Acceptance Date in respect of that Offshore Drilling Contract.

4. ONSHORE DRILLING CONTRACTS

4.1 Rosneft agrees that, subject to the satisfaction of the Conditions in Paragraphs 4 and 6(A) of Schedule 1 (Conditions to Completion), it shall procure that the relevant members of the Retained Group and the relevant members of the Sale Group execute each of the Onshore Drilling Contracts on or prior to, but conditional on, Completion. Rosneft agrees that the execution of each of the Onshore Drilling Contracts shall comply with the Procurement Law and Procurement Documentation of the relevant members of the Retained Group.

VTB Rigs

4.2 Rosneft shall procure that, between the Signing Date and Completion, the Sale Group shall enter into lease contracts with VTB Leasing for the lease of 28 (twenty eight) land rigs, details of which are set out in Part B of Attachment 3 (the “VTB Rigs”) (the “VTB Leases”). The VTB Leases shall be on substantially the same terms as the leases which are already in place as at the Signing Date between the Sale Group and VTB-Leasing and shall reflect the following principles:

(A) the VTB Rigs shall operate in Nefteyugansk;

(B) the VTB Rigs shall be delivered to the Sale Group at DDP Nefteyugansk (Pyt-Yakh) rail station (the “Delivery Location”) during the period from October 2014 to June 2015;

(C) the monthly lease payments to VTB Leasing in respect of each VTB Rig shall be as set out in the lease payment schedule in Part A of Attachment 7 (VTB Schedule);

(D) the Sale Group shall have the option exercisable at any time during the term of such VTB Leases to require VTB-Leasing to sell to the Sale Group such VTB Rigs as the Sale Group shall designate in writing. The purchase price for each VTB Rig shall be equal to the amount set out in the table entitled “ОРИЕНТИРОВОЧНЫЙ ГРАФИК ЛИЗИНГОВЫХ ПЛАТЕЖЕЙ” in each of Part B, Part C, Part D or Part E (as the case may be) of Attachment 7 (VTB Schedule); and

(E) VTB Leasing shall not be entitled to terminate the VTB Leases as a result of the change in ownership or control of the Sale Group pursuant to this Agreement and the Russian SPA and no break fee, termination payments, penalties or similar liabilities shall arise under the VTB Leases as a result of such change in ownership or control.

4.3 Subject to the entry into of the VTB Leases and the satisfaction of the Conditions in Paragraphs 4 and 6(A) of Schedule 1 (Conditions to Completion), Rosneft shall procure that the relevant members of the Retained Group and the relevant members of the Sale Group execute an Onshore Drilling Contract in respect of each of the VTB Rigs on or prior to, but conditional on, Completion. The parties agree that the Onshore Drilling Contracts will provide for the Retained Group to pay for the mobilisation from the Delivery Location to the drilling location.

4.4 Rosneft shall procure that the day rate for:

(D) the VTB Rigs under the Onshore Drilling Contracts shall, at all times during the five year term of such Onshore Drilling Contracts, be no less than:

(i) ***** per day (which number shall be increased by inflation of 6 per cent. per annum) (excluding VAT) for the Uralmash VTB Rigs; and

(ii) ***** per day (which number shall be increased by inflation of 6 per cent. per annum) (excluding VAT) for the ZJ-50DBS VTB Rigs; and

(E) the Leased Rigs under the Onshore Drilling Contracts shall, at all times during the five year term of such Onshore Drilling Contracts, be no less than:

(i) ***** per day (which number shall be increased by inflation of 6 per cent. per annum) (excluding VAT) for the Uralmash Leased Rigs; and

(ii) ***** per day (which number shall be increased by inflation of 6 per cent. per annum) (excluding VAT) for the ZJ-50DBS Leased Rigs.

Rosneft agrees that the provision of this Clause shall apply notwithstanding any relocation of any such VTB Rigs or Leased Rigs (as the case may be) from one region to another during the term of the Onshore Drilling Contracts.

5. EXTENDED CO-OPERATION

Transaction Documents

5.1 Each of Rosneft, Seadrill and NADL agrees that it shall seek to extend its co-operation with the other parties beyond Completion and on or prior to, but conditional on, Completion Seadrill and Rosneft shall execute the Shareholders’ Agreement.

Additional Drilling Contracts

5.2 Seadrill agrees and acknowledges that Rosneft’s objective is to increase its shareholding in NADL to 50% (fifty per cent.) less one (1) share in NADL and that this objective ideally will be achieved through the entry into of Additional Drilling Contracts and the related issue of NADL Additional Contract Shares to Rosneft or the transfer of Seadrill Additional Contract Shares to Rosneft pursuant to this Clause 5 (Extended Co-Operation). However, the parties further agree that to the extent that the issue of NADL Additional Contract Shares to Rosneft when combined with the transfer of Seadrill Additional Contract Shares to Rosneft, would result in Rosneft's shareholding in NADL exceeding 50% (fifty per cent.) less one (1) share in NADL then, notwithstanding any other provision in this Clause 5 (Extended Co-Operation), NADL shall only issue such number of NADL Additional Contract Shares to Rosneft or Seadrill shall only transfer such number of Seadrill Additional Contract Shares to Rosneft as results in Rosneft's shareholding in NADL not exceeding 50% (fifty per cent.) less one (1) share in NADL with an amount attributable to the value of the NADL Additional Contract Shares not issued or Seadrill Additional Contract Shares not transferred, as the case may be, being satisfied by a cash payment to Rosneft by NADL (if the amount is attributable to an Additional Drilling Contract with a member of the NADL Group) or Seadrill (if the amount is attributable to an Additional Drilling Contract with a member of the Seadrill Group) at the same time as the issue of the NADL Additional Contract Shares or transfer of the Seadrill Additional Contract Shares that are issued or transferred, respectively.

5.3 The parties shall bear their own costs of identifying and implementing opportunities and entering into any Additional Drilling Contracts unless otherwise agreed.

Additional Drilling Contracts with the NADL Group

5.4 Subject to Clause 5.2, if any member of the Retained Group and any member of the NADL Group agree to enter into any Additional Drilling Contract, then NADL shall issue NADL Additional Contract Shares to Rosneft within 5 Business Days from the Additional Contract Acceptance Date in respect of the relevant drilling rig.

5.5 Any NADL Additional Contract Shares issued pursuant to Clause 5.4 shall be credited as fully paid, with the same rights and ranking pari passu in all respects with the existing fully paid common shares of par value US$5 each in the share capital of NADL. NADL shall issue any NADL Additional Contract Shares free from all Encumbrances and from all other rights exercisable by or claims by third parties, together with all rights attached or accruing to them at the time of issue. NADL shall procure that all rights of pre-emption over any of the NADL Additional Contract Shares conferred by the constitutional documents of NADL, by applicable law or in any other way are waived prior to their issue.

True-up on each Settlement Date

5.6 As at each Settlement Date, NADL shall calculate:

(C) the amount (if any) by which A exceeds B where:

A = ***** of the aggregate Additional Contract Estimated Drilling Revenue in the Assessed Settlement Period under all Additional Drilling Contracts to which any member of the NADL Group is a party and in respect of which the Additional Contracts Acceptance Date has occurred; and

B = ***** of the aggregate Additional Contract Actual Drilling Revenue in the Assessed Settlement Period under all Additional Drilling Contracts to which any member of the NADL Group is party,

(such amount being the “Additional Contract Revenue Deficit”); or

(D) the amount (if any) by which X exceeds Y where:

X = ***** of the aggregate Additional Contract Actual Drilling Revenue in the Assessed Settlement Period under all Additional Drilling Contracts to which any member of the NADL Group is party; and

Y = ***** of the aggregate Additional Contract Estimated Drilling Revenue in the Assessed Settlement Period under all Additional Drilling Contracts to which any member of the NADL Group is a party and in respect of which the Additional Contracts Acceptance Date has occurred,

(such amount being the “Additional Contract Revenue Surplus”); and

(E) the Additional Contract Rolled Forward Amount (if any) or the Additional Contract Rolled Forward Surplus Amount (if any),

and notify those amounts to Rosneft in writing.

5.7 If there is an Additional Contract Revenue Deficit in respect of the Assessed Settlement Period and the aggregate of: (i) the Additional Contract Revenue Deficit in the Assessed Settlement Period; (ii) plus the Additional Contract Rolled Forward Amount (if any) or minus the Additional Contract Rolled Forward Surplus Amount (if any); and (iii) plus any amounts outstanding from Rosneft to NADL under this Agreement as at the Settlement Date in accordance with Clause 16.9 (the “Additional Contract Aggregate Deficit”) is:

(A) a positive amount and more than US$10,000,000, then NADL shall receive from Rosneft an amount equal to the Additional Contract Aggregate Deficit within 10 Business Days following receipt of the notice from NADL under Clause 5.6 and the Additional Contract Rolled Forward Amount and the Additional Contract Rolled Forward Surplus Amount shall then each be zero;

(B) a negative amount, then the Additional Contract Rolled Forward Surplus Amount shall then be equal to the modulus of the Additional Contract Aggregate Deficit; or

(C) a positive amount and less than or equal to US$10,000,000, then no true-up is required at that time and the Additional Contract Rolled Forward Amount shall then be an amount equal to the Additional Contract Aggregate Deficit and the Additional Contract Rolled Forward Surplus Amount shall then be zero.

5.8 If there is an Additional Contract Revenue Surplus in respect of the Assessed Settlement Period and the aggregate of: (i) the Additional Contract Revenue Surplus in the Assessed Settlement Period, (ii) less the Additional Contract Rolled Forward Amount (if any) or plus the Additional Contract Rolled Forward Surplus Amount (if any), (iii) less any amounts outstanding from Rosneft to NADL under this Agreement as at the Settlement Date (the “Additional Contract Aggregate Surplus”) is:

(A) a positive amount and more than $10,000,000, then, within 10 Business Days following that Settlement Date, NADL shall issue to Rosneft such number of NADL Additional Contract Shares (rounded up to the nearest whole number of shares) as equals A/B where:

A = the Additional Contract Aggregate Surplus; and

B =     the share price used to calculate the number of NADL Additional Contract Shares when they were issued, being “B” in the definition of NADL Additional Contract Shares,

and the Additional ContractRolled Forward Amount and the Additional Contract Rolled Forward Surplus Amount shall then be zero;

(B) a negative amount and more than $10,000,000, then NADL shall receive from Rosneft an amount equal to the Additional Contract Aggregate Surplus within 10 Business Days following receipt of the notice from NADL under Clause 5.6 and the Additional Contract Rolled Forward Amount and the Additional Contract Rolled Forward Surplus Amount shall then each be zero;

(C) a negative amount and less than or equal to US$10,000,000, then the Additional Contract Rolled Forward Amount shall then be equal to the modulus of the Additional Contract Aggregate Surplus; or

(D) a positive amount and less than or equal to $10,000,000, then no true up is required at that time and the Additional Contract Rolled Forward Surplus Amount shall be an amount equal to the Additional Contract Aggregate Surplus.

5.9 At the time of the termination or expiry of the last of the Offshore Drilling Contracts and outstanding Additional Drilling Contracts to which a member of the NADL Group is a party to terminate or expire:

(A) if there is an Additional Contract Rolled Forward Amount, Rosneft and NADL shall discuss an efficient mechanism for dealing with the remaining Additional Contract Rolled Forward Amount and, failing such agreement, Rosneft shall, either:

(i) on the Settlement Date immediately following such termination or expiry, elect to waive its dividend rights and Clause 16.9(B) shall apply; or

(ii) pay such amount to NADL within 10 Business Days following the Settlement Date following such termination or expiry provided that if such amount is subject to Russian withholding tax, Rosneft shall gross up the remaining Rolled Forward Amount in such a way that after deducting Russian withholding tax from the grossed up Rolled Forward Amount NADL receives an amount equal to the Rolled Forward Amount less an amount equal to 50% (fifty per cent.) of the tax being withheld; and

(B) if there is an Additional Contract Rolled Forward Surplus Amount, within 10 Business Days following such termination or expiry, NADL shall issue to Rosneft such number of common shares of par value US$5 each in the share capital of NADL (rounded up to the nearest whole number of shares) as equals A/B where:

A =     the Additional Contract Rolled Forward Surplus Amount; and

B = the share price used to calculate the number of NADL Additional Contract Shares when they were issued, being “B” in the definition of NADL Additional Contract Shares,

and the Additional Contract Rolled Forward Surplus Amount shall then be zero.

5.10 On each issue of NADL Additional Contract Shares, NADL shall deliver a share certificate for the relevant NADL Additional Contract Shares in the name of Rosneft.

5.11 Any Additional Contract Rolled Forward Amount and Additional Contract Rolled Forward Surplus Amount shall increase by an amount equal to LIBOR plus 4% (four per cent.), which shall accrue from day to day and shall form part of the Additional Contract Rolled Forward Amount or Additional Contract Rolled Forward Surplus Amount (as the case may be).

5.12 Where practicable, the parties will seek to combine and consolidate the true-up mechanisms and the provisions dealing with the issuance of the Contract Shares and the NADL Additional Contract Shares in Clause 3 (Contract Shares) and this Clause 5 (Extended Co-Operation) on any Settlement Date, Acceptance Date or Additional Contract Acceptance Date taking into account the differences in the share prices used in the calculations of the Contract Shares and the NADL Additional Contract Shares, including with the aim of simplifying the true-up provisions.

Additional Drilling Contracts with the Seadrill Group

5.13 Subject to Clause 5.2, if any member of the Retained Group and any member of the Seadrill Group agree to enter into any Additional Drilling Contract then Seadrill shall within 5 Business Days from the Additional Contract Acceptance Date in respect of the relevant drilling rig either:

(A) if Rosneft holds shares representing less than 50% (fifty per cent.) less one (1) share in NADL of all of the issued shares in NADL,transfer Seadrill Additional Contract Shares to Rosneft, provided that to the extent that the transfer of Seadrill Additional Contract Shares to Rosneft would result in Seadrill holding less than 10% (ten per cent.) of the share capital of NADL at such time, Seadrill shall satisfy its obligations under this Clause 5.13 by the transfer of an equivalent amount in cash to Rosneft; or

(B) if Rosneft holds shares representing 50% (fifty per cent.) less one (1) share in NADL or more of all the issued shares in NADL, pay in cash to Rosneft an amount equal to (i) ***** of the Additional Contract Estimated Drilling Revenue for that Additional Drilling Contract (ii) minus the Seadrill Additional Contract Rolled Forward Amount (if any) or plus the Seadrill Additional Contract Rolled Forward Surplus Amount (if any) in each case as at the Additional Contract Acceptance Date under that Additional Drilling Contract and (iii) minus any amounts outstanding from Rosneft to Seadrill under this Agreement as at the Additional Contract Acceptance Date under that Additional Drilling Contract.

5.14 Any Seadrill Additional Contract Shares transferred pursuant to Clause 5.13 shall be fully paid and transferred free from all Encumbrances and from all other rights exercisable by or claims by third parties, together with all rights attached or accruing to them at the date of transfer.

Rosneft and NADL agree that the process of developing and agreeing Work Orders is not intended to be an opportunity for the Retained Group or the Sale Group to renegotiate the commercial terms of the Onshore Drilling Contracts.

5.23 The parties agree that the intention is for the Sale Group to make the Land Rigs available to Rosneft under the Onshore Drilling Contracts. Rosneft shall procure that all of the Land Rigs shall be the subject of a Work Order between the Retained Group and the Sale Group at all times throughout the five (5) year period following the Completion Date and shall pay on demand to NADL any losses suffered by NADL and/or any member of the Sale Group if any of the Land Rigs are not so subject (subject in each case to NADL acting in accordance with Clause 5.22 and the relevant members of the Sale Group not unreasonably withholding their agreement to the Work Orders in accordance with the Onshore Drilling Contract).

5.24 NADL shall procure that the relevant members of the Sale Group do not unreasonably withhold their agreement to the Work Orders as described in Clause 5.23.

5.27 In the period between the Signing Date and Completion, Rosneft and NADL shall procure that the Working Party shall:

(A) prepare and finalise each of the Onshore Drilling Contracts based on the Pro forma Onshore Drilling Contract; and

(B) prepare and agree the initial Work Orders which will be signed at Completion for all of the Land Rigs under the Onshore Drilling Contracts.

5.28 The parties agree that, subject to Clause 5.26 and 5.27, the only changes that should be made to the Pro forma Onshore Drilling Contract should be such changes as are reasonably necessary to deal with business processes, logistical and drilling issues and norms arising in each specific region.

Liability caps under the Onshore Drilling Contracts

5.29 Notwithstanding anything to the contrary in any of the Onshore Drilling Contracts, but subject to Clauses 5.31 and 5.32:

(A) the maximum aggregate liability of the NADL Group (subject to Clauses 5.29(B) and (C)):

(i) in respect of each well under the Onshore Drilling Contracts shall be:

(a) where there has been negligence of the NADL Group, *****; and

(b) where there has been gross negligence of the NADL Group, *****,

(such appropriate amount being the "Relevant Well Tier One Liability Cap"); and

(ii) in respect of any and all wells under all Onshore Drilling Contracts shall be ***** in aggregate (the "Aggregate Tier One Liability Cap");

(B) where the aggregate liability of the NADL Group under the Onshore Drilling Contracts in respect of all wells reaches the Aggregate Tier One Liability Cap, then, in respect of all further wells under any and all Onshore Drilling Contracts after that time, the maximum aggregate liability of the NADL Group (subject to Clause 5.29(C)):

(i) in respect of each such well under the Onshore Drilling Contracts shall be:

(a) where there has been negligence of the NADL Group, reduced from ***** to *****;

(b) where there has been gross negligence of the NADL Group, reduced from ***** to *****,

(such appropriate amount being the "Relevant Well Tier Two Liability Cap"); and

(ii) in respect of any and all wells under all Onshore Drilling Contracts shall be ***** in aggregate (the "Aggregate Tier Two Liability Cap"); and

(C) where the aggregate liability of the NADL Group under the Onshore Drilling Contracts in respect of all wells reaches the Aggregate Tier Two Liability Cap, then, in respect of all further wells under any and all Onshore Drilling Contracts after that time, the maximum aggregate liability of the NADL Group in respect of each such well under the Onshore Drilling Contracts shall be:

(i) where has been negligence of the NADL Group, reduced from ***** to *****; and

(ii) where has been gross negligence of the NADL Group, reduced from ***** to *****,

(such appropriate amount being the "Relevant Well Tier Three Liability Cap").

5.30 Rosneft shall procure that the Retained Group shall give effect to the provisions set out in Clause 5.29 and, to the extent that payments are made by the NADL Group at any time in excess of the liability caps set out in Clause 5.29, then Rosneft shall pay to NADL promptly on demand the difference between the amount paid by the NADL Group and the amount that should have been paid by the NADL Group in accordance with Clause 5.29. For the avoidance of doubt notwithstanding anything to the contrary in this Agreement, but subject to the caps on liability provided for in Clauses 5.29 to 5.33 (inclusive), the parties agree that liability under the Onshore Drilling Contracts shall be assessed under the terms of those Onshore Drilling Contracts.

5.31 The parties agree that, in the event that any of the rates set out in Appendix 4.1 of the Onshore Drilling Contracts increase, then each of the liability caps set out in Clause 5.29 above shall be increased by an amount equal to X in the following formula:

X = Y x (Z x 0.5)

where:

Y = the relevant liability cap immediately prior to the operation of this Clause 5.31; and

(ii) the Relevant Well Tier One Liability Cap,

then Rosneft shall have the right by written notice to NADL to elect to make the claim instead subject to the Aggregate Tier Two Liability Cap and the Relevant Well Tier Two Liability Cap.

(i) the value of the claim; and

(ii) the Relevant Well Tier Two Liability Cap,

then Rosneft shall have the right by written notice to NADL to elect to make the claim instead subject to the Relevant Well Tier Three Liability Cap. Upon such notice from Rosneft being received by NADL, the Relevant Well Tier Three Liability Cap shall not increase.

(E) is accurate in all respects and not misleading at the Signing Date, except as disclosed in the Original Rosneft Disclosure Letter; and

(F) will be accurate in all respects and not misleading at the Completion Date as if repeated immediately before Completion by reference to the facts and circumstances subsisting at that date on the basis that any reference in the Rosneft Warranties, whether express or implied, to the Signing Date is substituted by a reference to the Completion Date, except as disclosed in any updated disclosure letter which shall be in equivalent form to the Original Rosneft Disclosure Letter and delivered by Rosneft to Seadrill and NADL not later than five (5) Business Days prior to the Completion Date (the “Updated Rosneft Disclosure Letter”). The Updated Rosneft Disclosure Letter shall not:

(i) contain any disclosure of facts or circumstances which were known by Rosneft on or before the Signing Date (“Known Matters”), and to the extent the Updated Rosneft Disclosure Letter does contain any Known Matters such Known Matters shall not qualify the Rosneft Warranties or limit Rosneft’s liability in any way in respect thereof; or

(ii) contain any disclosure against any of the Key Rosneft Warranties (“Key Warranty Disclosure”), and to the extent the Updated Rosneft Disclosure Letter does contain any Key Warranty Disclosure such Key Warranty Disclosure shall not qualify the Key Rosneft Warranties or limit Rosneft’s liability in any way in respect thereof.

For the purposes of Clause 12.1(A) above and any Rosneft Warranty given at the Signing Date (and for the purposes of Paragraph 3 of Part A of Schedule 7 (Limitations on liability) insofar as it applies to Clause 12.1(A)), if the text of any Rosneft Warranty refers to the “Updated Rosneft Disclosure Letter” or the “Current Rosneft Disclosure Letter” such reference shall be deemed to be a reference to the Original Rosneft Disclosure Letter, the intention being that only matters set out in the Original Rosneft Disclosure Letter can be disclosed against those Rosneft Warranties given at the Signing Date.

(E) excluded from the calculation of the Completion Working Capital Amount a category of asset which was not excluded in the calculation of the Minimum Working Capital Amount as evidenced by Part E of this Schedule 8,

Notwithstanding the above, Rosneft shall not include in any amended calculation of the Minimum Working Capital Amount liabilities of the type described in Paragraphs 15 and 17 of Part C of Schedule 8.

(I) if Rosneft and NADL do not reach agreement in accordance with Paragraph (A) above, Rosneft or NADL may refer the dispute in respect of only the Disputed Items still remaining in dispute (and not those items of the Draft Completion Accounts that have been agreed between Rosneft and NADL in accordance with Paragraph (A) above) to such individual at one of KPMG or Ernst & Young as Rosneft and NADL may agree or, failing such agreement within 10 calendar days of expiry of the period described in Paragraph (A) above, to such independent firm of international standing as the President of the Institute of Chartered Accountants in England and Wales may, on the application of either Rosneft or NADL, nominate (the “Expert”), on the basis that the Expert is to make a decision on the dispute and notify Rosneft and NADL of its decision within 60 Business Days of receiving the reference or such longer reasonable period as the Expert may determine.

b. any penalties or early termination fees payable on the termination of the following contracts only:

(i) contracts in relation to indebtedness or borrowings of the Sale Group; and

(ii) drilling contracts of the Sale Group with Gazpromneft-Noyabrskneftegaz and Gazpromneft Orenburg

(i)if, while a registration request is pending pursuant to this Section 2(a), the Company determines, following consultation with and receiving advice from its legal counsel, that the filing of a registration statement would require the disclosure of material information that the Company has a bona fide business purpose for preserving as confidential and the disclosure of which the Company determines reasonably and in good faith would have a material adverse effect on any active proposal by the Company or its Subsidiaries to engage in any material acquisition, merger, consolidation, tender offer, business combination, reorganization or other material transaction, the Company shall not be required to effect a registration pursuant to this Section 2(a) until the earlier of (A) the date upon which such material information is otherwise disclosed to the public or ceases to be material and (B) 30 days after the Company makes such determination, provided, however, that the Company shall not be permitted to delay a requested registration in reliance on this clause (i) more than once in any 12-month period; provided, further, that, notwithstanding the foregoing, no such delay shall exceed such number of days that the Company determines in good faith to be reasonably necessary;

(ii)the Company shall not be obligated to file a registration statement relating to a registration request pursuant to this Section 2: (A) before the end of any applicable lock-up period; or (B) on more than three separate occasions; and

(iii)the Company shall not be required to file a separate registration statement, but may file one registration statement covering the Registrable Securities held by more than one Holder.

(d)The Company shall have the right to cause the registration of additional securities for sale for the account of any person (including the Company) in any registration of Registrable Securities requested by any Holder pursuant to Section 2(a); provided, however, that if the managing underwriter or other independent marketing agent for such offering (if any) determines that, in its opinion, the additional securities proposed to be sold will materially and adversely affect the offering and sale of the Registrable Securities to be registered in accordance with the intended method or methods of disposition then contemplated by such Holder, only the number or principal amount of such additional securities, if any (in excess of the number or principal amount of Registrable Securities), which, in the opinion of such underwriter or agent, can be so sold without materially and adversely affecting such offering shall be included in such registration. The rights of a Holder to cause the registration of additional Registrable Securities held by such Holder in any registration of Registrable Securities requested by another Holder pursuant to Section 2(a) shall be governed by the agreement of the Holders with respect thereto as provided in Section 11(a).

3.Piggyback Registration. If the Company proposes to register any of its Common Shares or any of its other securities (such Common Shares and other securities collectively, “Other Securities”) under the Securities Act, whether or not for sale for its own account, in a manner which would permit registration of Registrable Securities under the Securities Act, it will at such time give prompt written notice to each Holder of its intention to do so (and, in any event, no later than 15 business days prior to the anticipated filing date of the registration statement relating to such registration). Such notice shall offer each such Holder the opportunity to include in such registration statement such number of Registrable Securities as each such Holder may request. Upon the written request of any such Holder made within 10 business days after the receipt of the Company’s notice (which request shall specify the number of Registrable Securities intended to be disposed of and the intended method of disposition thereof), the Company shall effect, in the manner set forth in Section 5, in connection with the registration of the Other Securities, the registration under the Securities Act of all Registrable Securities which the Company has been so requested to register, to the extent required to permit the disposition (in accordance with such intended methods thereof) of the Registrable Securities so requested to be registered, provided that:

(a)if at any time after giving written notice of its intention to register any securities and prior to the effective date of such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company may, at its election, give written notice of such determination to the Holders and, thereupon, (A) in the case of a determination not to register, the Company shall be relieved of its obligation to register any Registrable Securities in connection with such registration and (B) in the case of a determination to delay such registration, the Company shall be permitted to delay registration of any Registrable Securities requested to be included in such registration for the same period as the delay in registering such Other Securities, but, in either such case, without prejudice to the rights of the Holders under Section 2;

(b)%4 if the registration referred to in the first sentence of this Section 3 is to be a registration in connection with an underwritten offering on behalf of any of the Company, holders of securities (other than Registrable Securities) of the Company (“Other Holders”) or Holders of Registrable Securities, and the managing underwriter for such offering advises the Company in writing that, in such firm’s opinion, such offering would be materially and adversely affected by the inclusion therein of Registrable Securities requested to be included therein pursuant to this Section 3 because such Registrable Securities are not of the same type, class or series as the securities to be offered and sold in such offering on behalf of the Company, the Other Holders and/or the Holders of Registrable Securities, the Company may exclude all such Registrable Securities requested to be included therein pursuant to this Section 3 from such offering;

(ii)if the registration referred to in the first sentence of this Section 3 is to be a registration in connection with an underwritten secondary offering on behalf of Other Holders made pursuant to demand registration rights granted by the Company to such Other Holders or on behalf of a Holder of Registrable Securities made pursuant to Section 2 of this Agreement (the “Initiating Holders”), and the managing underwriter for such offering advises the Company in writing that, in such firm’s opinion, such offering would be materially and adversely affected by the inclusion therein of the Holder’s Registrable Securities requested to be included therein pursuant to this Section 3 because the number or principal amount of such Registrable Securities, considered together with the number or principal amount of securities proposed to be offered by the Initiating Holders, exceeds the Maximum Marketable Amount, the Company shall include in such registration: (1) first, all securities any such Initiating Holder proposes to sell for its own account (the “Initiating Holder Securities”); (2) second, the number or principal amount of such Registrable Securities (in excess of the number or principal amount of Initiating Holder Securities) which, in the opinion of such underwriter, can be sold without materially and adversely affecting such offering (allocated among the Holders in accordance with the agreement of the Holders with respect thereto as provided in Section 11(a)); and (3) third, the number or principal amount of securities, if any, requested to be included therein by (x) Other Holders to which clause (1) does not apply or (y) the Company (in excess of the number or principal amount of Initiating Holder Securities and such Registrable Securities) which, in the opinion of such underwriter, can be so sold without materially and adversely affecting such offering (allocated among such Other Holders and the Company on the basis of the number or principal amount of the securities requested to be included therein by each such Other Holder or the Company; and

(d)each Holder shall have the right to withdraw such Holder’s request for inclusion of its Registrable Securities in any underwritten public offering pursuant to this Section 3 at any time prior to the execution of an underwriting agreement with respect thereto by giving written notice to the Company of such Holder’s request to withdraw and, subject to the preceding clause, each Holder shall be permitted to withdraw all or part of such Holder’s Registrable Securities from a registration pursuant to this Section 3 at any time prior to the effective date thereof; and

(e)no registration of Registrable Securities effected under this Section 3 shall relieve the Company of its obligation to effect any registration of Registrable Securities required of the Company pursuant to Section 2 hereof.

(a)prepare and file a registration statement under the Securities Act relating to the Registrable Securities to be offered as soon as practicable, but in no event later than 45 days (60 days if the applicable registration form is other than Form F-3 or Form S-3) after the date notice is given, and use its reasonable best efforts to cause the same to become effective as soon as practicable thereafter, but in no event later than 135 days after the date notice is given (150 days if the applicable registration form is other than Form F-3 or Form S-3); provided that, a reasonable time before filing a registration statement or prospectus, or any amendments or supplements thereto (other than reports required to be filed by it under the Exchange Act and the rules and regulations adopted by the SEC thereunder), the Company will furnish to the Holders and their counsel and other representatives (including underwriters) for review and comment, copies of all documents proposed to be filed; and provided further, that if a Holder so requests (i) it and its counsel and other representatives (including underwriters) may participate in the drafting and preparation of such registration statement and prospectus and (ii) such information as it believes may be beneficial to be included in the registration statement and prospectus for marketing purposes shall be included therein so long as disclosure of such information is in compliance with applicable law;

(b)prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective with respect to the disposition of all Registrable Securities included therein and to otherwise comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities included therein until the earlier of (i) such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition set forth in such registration statement and (ii) the expiration of nine months (three years if the registration statement is a Form F-3 or Form S-3) after such registration statement becomes effective; provided, that such nine-month period shall be extended for such number of days that equals the number of days elapsing from (A) the date the written notice contemplated by paragraph (g) below is given by the Company to (B) the date on which the Company delivers to the Holders of Registrable Securities the supplement or amendment contemplated by paragraph (g) below;

(c)furnish to the Holders and to any underwriter of such Registrable Securities such number of conformed copies of such registration statement and of each amendment thereto (in each case including all exhibits), such number of copies of the prospectus included in such registration statement (including each preliminary prospectus and any summary prospectus) and of each supplement thereto, and of each free writing prospectus (as defined in Rule 405 under the Securities Act), in conformity with the requirements of the Securities Act, and such other documents, as the Holders or such underwriter may reasonably request in order to facilitate the public sale of the Registrable Securities, and a copy of any and all transmittal letters or other correspondence to, or received from, the SEC or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering;

(d)use its reasonable best efforts to register or qualify all Registrable Securities covered by such registration statement under the securities or blue sky laws of such jurisdictions (domestic or foreign) as the Holders or any underwriter of such Registrable Securities shall reasonably request, and use its reasonable best efforts to obtain all appropriate registrations, permits and consents required in connection therewith, and do any and all other acts and things which may be necessary or advisable to enable the Holders or any such underwriter to consummate the disposition in such jurisdictions of its Registrable Securities covered by such registration statement; provided that the Company shall not for any such purpose be required to register or qualify generally to do business as a foreign corporation in any jurisdiction wherein it is not so qualified, or to subject itself to taxation in any such jurisdiction, or to consent to general service of process in any such jurisdiction;

(e)(i) use its best efforts to furnish one or more opinions of counsel for the Company addressed to the underwriters and each Holder of Registrable Securities included in such registration (each a “Selling Holder”) dated the date of any closing under the underwriting agreement (if any) (or if such offering is not underwritten, dated the effective date of the registration statement), and (ii) use its best efforts to furnish one or more “comfort” letters addressed to the underwriters and each Selling Holder, if permissible under applicable accounting practices, and signed by the independent public accountants who have audited the Company’s financial statements included in such registration statement (or any financial statements of an acquired business or any other financial statements included in such registration statement), in each such case covering substantially the same matters with respect to such registration statement (and the prospectus included therein) as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters in underwritten public offerings of securities and such other matters as the Selling Holders may reasonably request and, in the case of such accountants’ letters, with respect to events subsequent to the date of such financial statements;

(f)immediately notify the Selling Holders in writing (i) at any time when a prospectus relating to a registration pursuant to Section 2 or 3 hereof is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, (ii) of any request by the SEC or any other regulatory body or other body having jurisdiction for any amendment of or supplement to any registration statement or other document relating to such offering, and (iii) of the issuance by the SEC of any stop order suspending the effectiveness of any registration statement relating to such offering or the initiation of proceedings for that purpose and in any such case (i), (ii) or (iii) at the request of the Selling Holders, promptly prepare and furnish to the Selling Holders a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include 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, in light of the circumstances under which they are made, not misleading, to comply with such request by the SEC or any other regulatory authority or to remove such stop order;

(g)use its reasonable best efforts to list all such Registrable Securities covered by such registration on each securities exchange and inter-dealer quotation system on which the Common Shares is then listed and, if the Registrable Securities are a class of Common Shares that is not then so listed, then to list such securities on a securities exchange or inter-dealer quotation system selected by the holders of at least a majority of such Registrable Securities;

(h)use its reasonable best efforts to list all Registrable Securities covered by such registration statement on any securities exchange or inter-dealer quotation system (in each case, domestic or foreign) not described in paragraph (g) above as the Selling Holders or any underwriter of such Registrable Securities shall request, and use its reasonable best efforts to obtain all appropriate registrations, permits and consents required in connection therewith, and to do any and all other acts and things which may be necessary or advisable to effect such listing;

(i)to the extent reasonably requested by the lead or managing underwriters in connection with any underwritten offering, send appropriate officers of the Company to participate in any “road shows” and other customary marketing activities in connection with any such registration;

(j)use its reasonable best efforts to comply with all applicable rules of the SEC and to make available to its security holders, as soon as reasonably practicable (but not more than one hundred and twenty (120) days after the end of the twelve-month period beginning with the effective date of the registration statement), an earnings statement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations promulgated thereunder;

(k)without limiting Section 5(e) above, use its reasonable best efforts to cause such Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the holders of such Registrable Securities to consummate the disposition of such Registrable Securities in accordance with their intended method of distribution thereof;

(l)without limiting the generality of any other provision of this Agreement, permit any Holder of Registrable Securities which Holder, in its reasonable judgment, might be deemed to be an underwriter or a controlling person of the Company, to participate in the preparation of such Registration Statement and to require the insertion therein of language, furnished to the Company in writing, which in the reasonable judgment of such Holder and its counsel should be included; provided however that such language shall be removed if objected to by the Staff of the Securities and Exchange Commission; and

(m)otherwise use its reasonable best efforts to take all other steps necessary to effect the registration of such Registrable Securities contemplated hereby.

The Company may require each Selling Holder to furnish the Company with such information regarding such Selling Holder and pertinent to the disclosure requirements relating to the registration and the distribution of such securities as the Company may from time to time reasonably request.

7.Underwriting; Due Diligence.

(a)If requested by the underwriters for any underwritten offering of Registrable Securities pursuant to a registration requested under this Agreement, the Company shall enter into an underwriting agreement with such underwriters for such offering, such agreement to contain such representations and warranties by the Company and such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions, including, without limitation, indemnities and contribution substantially to the effect and to the extent provided in Section 8 hereof and the provision of opinions of counsel and accountants’ letters to the effect and to the extent provided in Section 5(f) hereof and customary lock-up agreements. The Selling Holders on whose behalf the Registrable Securities are to be distributed by such underwriters shall be parties to any such underwriting agreement. Such underwriting agreement shall also contain such representations and warranties by the Selling Holders on whose behalf the Registrable Securities are to be distributed as are customarily contained in underwriting agreements with respect to secondary distributions (provided, for the sake of clarity, that such representations and warranties shall not include any representations and warranties other than those regarding such Selling Holder, such Selling Holder’s ownership of Registrable Securities to be sold in the offering and such Selling Holder’s intended method of distribution). The Selling Holders may require that any additional securities included in an offering proposed by a Holder be included on the same terms and conditions as the Registrable Securities that are included therein.

(b)In the event that any registration pursuant to Section 3 shall involve, in whole or in part, an underwritten offering, the Company may require the Registrable Securities requested to be registered pursuant to Section 3 to be included in such underwritten offering on the same terms and conditions as shall be applicable to the other securities being sold through underwriters under such registration. If requested by the underwriters for such underwritten offering, the Selling Holders on whose behalf the Registrable Securities are to be distributed shall enter into an underwriting agreement with such underwriters, such agreement to contain such representations and warranties by the Selling Holders (provided, for the sake of clarity, that such representations and warranties shall not include any representations and warranties other than those regarding such Selling Holder, such Selling Holder’s ownership of Registrable Securities to be sold in the offering and such Selling Holder’s intended method of distribution) and such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions, including, without limitation, indemnities and contribution substantially to the effect and to the extent provided in Section 8 hereof and customary lock-up agreements.

(c)In connection with the preparation and filing of each registration statement registering Registrable Securities under the Securities Act, the Company shall give the Holders of such Registrable Securities and the Underwriters, if any, and their respective counsel and accountants, such reasonable and customary access to its books and records and such opportunities to discuss the business of the Company with its officers and the independent public accountants who have certified the Company’s financial statements as shall be necessary, in the opinion of such Holders and such underwriters or their respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act.

8.Indemnification and Contribution.

(a)In the case of each offering of Registrable Securities made pursuant to this Agreement, the Company agrees to indemnify and hold harmless each Holder, its officers and directors, each underwriter of Registrable Securities so offered and each person, if any, who controls any of the foregoing persons within the meaning of the Securities Act, from and against any and all claims, liabilities, losses, damages, expenses and judgments, joint or several, to which they or any of them may become subject, under the Securities Act or otherwise, including any amount paid in settlement of any litigation commenced or threatened, and shall promptly reimburse them, as and when incurred, for any reasonable legal or other expenses incurred by them in connection with investigating any claims and defending any actions, insofar as such losses, claims, damages, liabilities or actions shall arise out of, or shall be based upon, any untrue statement or alleged untrue statement of a material fact contained in the registration statement (or in any preliminary or final prospectus included therein) or any free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) or any amendment or supplement thereto, or in any document incorporated by reference therein, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Company shall not be liable to a particular Holder in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement, or any omission, if such statement or omission shall have been made in reliance upon and in conformity with information relating to such Holder furnished to the Company in writing by or on behalf of such Holder and identified in such writing as being specifically for use in the preparation of the registration statement (or in any preliminary or final prospectus included therein) or any free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) or any amendment or supplement thereto. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of a Holder and shall survive the transfer of such securities. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to each Holder, any of such Holder’s directors or officers, underwriters of the Registrable Securities or any controlling person of the foregoing; provided, further, that this indemnity does not apply in favor of any underwriter or person controlling an underwriter (or, if a Selling Holder offers Registrable Securities directly without an underwriter, the Selling Holder) to the extent that any loss, liability, claim, damage or expense arises out of or is (i) based upon any untrue statement or alleged untrue statement or omission or alleged omission in the registration statement (or in any preliminary or final prospectus included therein) or any free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) that has been corrected in a subsequent applicable filing with the SEC but such underwriter or person controlling the underwriter (or the Selling Holder, if the Selling Holder offered the Registrable Securities directly without an underwriter) nonetheless failed to provide such corrected filing to the person asserting such loss, claim, damage, liability or action at or prior to the written confirmation of the sale of the Registrable Securities as required by the Securities Act or (ii) the gross negligence or willful misconduct of the underwriter or person controlling the underwriter (or, if a Selling Holder offers Registrable Securities directly without an underwriter, the Selling Holder).

(b)In the case of each offering made pursuant to this Agreement, each Holder of Registrable Securities included in such offering, by exercising its registration rights hereunder, agrees to indemnify and hold harmless the Company, its officers and directors and each person, if any, who controls any of the foregoing within the meaning of the Securities Act (and if requested by the underwriters, each underwriter who participates in the offering and each person, if any, who controls any such underwriter within the meaning of the Securities Act), from and against any and all claims, liabilities, losses, damages, expenses and judgments, joint or several, to which they or any of them may become subject, under the Securities Act or otherwise, including any amount paid in settlement of any litigation commenced or threatened, and shall promptly reimburse them, as and when incurred, for any legal or other expenses incurred by them in connection with investigating any claim and defending any actions, insofar as any such losses, claims, damages, liabilities or actions shall arise out of, or shall be based upon, any untrue statement or alleged untrue statement of a material fact contained in the registration statement (or in any preliminary or final prospectus included therein) or any free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that such untrue statement of a material fact is contained in, or such material fact is omitted from, information relating to such Holder furnished in writing to the Company by or on behalf of such Holder and identified in such writing as being specifically for use in the preparation of such registration statement (or in any preliminary or final prospectus included therein) or any free writing prospectus (as defined in Rule 405 promulgated under the Securities Act). The foregoing indemnity is in addition to any liability which such Holder may otherwise have to the Company, any of its directors or officers, underwriters who participate in the offering or any controlling person of the foregoing; provided, however, that this indemnity does not apply in favor of any underwriter or person controlling an underwriter (or, if the Company offers Registrable Securities directly without an underwriter, the Company) to the extent that any loss, liability, claim, damage or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission in the registration statement (or in any preliminary or final prospectus included therein) or any free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) that has been corrected in a subsequent applicable filing with the SEC but such underwriter or person controlling the underwriter (or the Company, if the Company offered the Registrable Securities directly without an underwriter) nonetheless failed to provide such corrected filing to the person asserting such loss, claim, damage, liability or action at or prior to the written confirmation of the sale of the Registrable Securities as required by the Securities Act.

(c)Each party indemnified under Paragraph (a) or (b) of this Section 8 shall, promptly after receipt of notice of any claim or the commencement of any action against such indemnified party in respect of which indemnity may be sought, notify the indemnifying party in writing of the claim or the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party on account of the indemnity agreement contained in paragraph (a) or (b) of this Section 8, except to the extent the indemnifying party was materially prejudiced by such failure, and in no event shall relieve the indemnifying party from any other liability which it may have to such indemnified party. If any such claim or action shall be brought against an indemnified party, and such indemnified party notifies the indemnifying party thereof, the indemnifying party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party, if each indemnifying party confirms in writing to the indemnified party that such indemnifying party has the obligation to indemnify the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided that each indemnified party, its officers and directors, if any, and each person, if any, who controls such indemnified party within the meaning of the Securities Act, shall have the right to employ separate counsel reasonably approved by the indemnifying party to represent them if the named parties to any action (including any impleaded parties) include both such indemnified party and an indemnifying party or an Affiliate of an indemnifying party, and such indemnified party shall have been advised by counsel that a conflict may exist between such indemnified party and such indemnifying party or such Affiliate that makes representation by the same counsel inadvisable, or if the indemnified party has concluded that there may be one or more legal or equitable defenses available to such indemnified party which are additional to or in conflict with those available to the indemnifying party, or such claim or action seeks an injunction or equitable relief against an indemnified party or involves actual or alleged criminal activity, or such claim or action involves or could have an effect upon matters beyond the scope of the indemnity provided herein, and in any such case the fees and expenses of one such separate counsel for all such indemnified parties shall be paid by the indemnifying party. An indemnified party will not enter into any settlement agreement which is not approved by the indemnifying party, such approval not to be unreasonably withheld, delayed or conditioned. The indemnifying party may not agree to any settlement of any such claim or action which (i) provides for any remedy or relief other than monetary damages for which the indemnifying party shall be responsible hereunder or (ii) does not include as an unconditional term thereof the delivery by each claimant or plaintiff to each indemnified party a written full and unconditional release from all liability in respect of such claim or action, without the prior written consent of the indemnified party. In any action hereunder as to which the indemnifying party has assumed the defense thereof with counsel reasonably satisfactory to the indemnified party, the indemnified party shall continue to be entitled to participate in the defense thereof, with counsel of its own choice, but, except as set forth above, the indemnifying party shall not be obligated hereunder to reimburse the indemnified party for the costs thereof.

(d)If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to herein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information related to and supplied by the indemnifying party on the one hand or the indemnified party on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission, but not by reference to any indemnified party’s stock ownership in the Company. In no event, however, shall a Holder be required to contribute in excess of the amount of the net proceeds received by such Holder in connection with the sale of Registrable Securities in the offering which is the subject of such loss, claim, damage or liability. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this paragraph shall be deemed to include, for purposes of this paragraph, any legal or other expenses reasonably incurred by such indemnifying party in connection with investigating, preparing to defend or defending any such action or claim or appearing as a third party witness with respect thereto. 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 such fraudulent misrepresentation.

9.Rule 144/Form F-3 or Form S-3. The Company shall take such measures and file such information, documents and reports as shall be required by the SEC as a condition to the availability of Rule 144 (or any successor provision). The Company shall use its reasonable best efforts to cause all conditions to the availability of Form F-3 or Form S-3 (or any successor form thereto) under the Securities Act for the filing of registration statements under this Agreement to be met (except for conditions that relate to the number of securities of the Company owned by non-affiliates of the Company).

10.Holdback.

(a)Each Holder agrees, if so required by the managing underwriter of any offering of equity securities by the Company and provided that the Company and each of its executive officers and directors enter into similar agreements, not to sell, make any short sale of, loan, grant any option for the purchase of, effect any public sale or distribution of or otherwise dispose of any Registrable Securities owned by such Holder, during the 7 days prior to and the 90 days after the registration statement relating to such offering has become effective (or such shorter period as may be required by the underwriter), except as part of such underwritten offering. Notwithstanding the foregoing sentence, each Holder subject to the foregoing sentence shall be entitled at any time to (i) deliver shares of Common Shares or other securities upon the exercise of an option or warrant or the conversion or exchange of a security outstanding on such date, (ii) sell any Registrable Securities acquired in open market transactions after the completion of such underwritten offering, (iii) sell any Registrable Securities in a transaction in which the purchaser agrees to be bound by the restrictions contained in the foregoing sentence and (iv) in the case of a Holder or its Affiliates, effect any distribution of shares of Common Shares to the holders of its shares by means of a distribution or exchange offer in a transaction intended to qualify as a tax-free distribution under Section 355 of the Internal Revenue Code, as amended, or any corresponding provision of any successor statute. The Company may legend and may impose stop transfer instructions on any certificate evidencing Registrable Securities relating to the restrictions provided for in this Section 10. The Holders shall not be subject to the restrictions set forth in this Section 10(a) for longer than 97 days during any 12-month period and a Holder shall no longer be subject to such restrictions at such time as such Holder together with its Affiliates shall own less than 5% of the then outstanding shares of Common Shares on a fully-diluted basis. Notwithstanding anything to the contrary in this Section 10, each Holder of Registrable Securities shall be released, pro rata, from any agreement entered into pursuant to this Section 10 in the event and to the extent that the managing underwriter or the Company permit any discretionary waiver or termination of the restrictions in any such agreement pertaining to any officer, director or other holder of shares of Common Shares subject to such an agreement.

(b)The Company agrees, if so required by the managing underwriter of any offering of Registrable Securities, not to sell, make any short sale of, loan, grant any option for the purchase of, effect any public sale or distribution of or otherwise dispose of any of its equity securities during the 30 days prior to and the 90 days after any underwritten registration pursuant to Section 2 or 3 hereof has become effective, except as part of such underwritten registration. Notwithstanding the foregoing sentence, the Company shall be entitled to (i) issue shares of Common Shares or other securities upon the exercise of an option or warrant, the settlement of any securities pursuant to employee benefit plans or the conversion or exchange of a security outstanding on such date, (ii) grant shares of Common Shares or other securities pursuant to employee benefit plans in effect on such date and (iii) sell shares of Common Shares or other securities in a transaction in which the purchaser agrees to be bound by the restrictions contained in the preceding paragraph. The Company shall use its reasonable best efforts to obtain and enforce similar agreements from any other Persons (other than the Holders, to which Section 10(a) applies) if requested by the managing underwriter of such offering.

11.Transfer of Registration Rights.

(a)A Holder may, subject to the terms of the shareholders’ agreement between Seadrill and Rosneft, transfer all or any portion of its rights under this Agreement to any transferee of a number of Registrable Securities that represents (assuming the conversion, exchange or exercise of all Registrable Securities so transferred that are convertible into or exercisable or exchangeable for the Company’s Common Shares) at least 5% of the then issued and outstanding Common Shares of the Company (each, a “Permitted Transferee”). Any Holder electing to transfer registration rights pursuant to this Section shall provide the Company with written notice promptly following such Holder’s execution of a binding agreement to transfer Registrable Securities. Such notice shall state the name and address of any Permitted Transferee and identify the number and/or aggregate principal amount of Registrable Securities with respect to which the rights under this Agreement are being transferred and the scope of the rights so transferred. In connection with any such transfer, the term “Holder” as used in this Agreement (other than in Sections 2(a)(ii) and 5(a)) shall, where appropriate to assign the rights and obligations hereunder to such Permitted Transferee, be deemed to refer to the Permitted Transferee of such Registrable Securities. Holders and any Permitted Transferees may exercise the registration rights hereunder in such priority, as among themselves, as they shall agree among themselves, and the Company shall observe any such agreements of which it shall have notice as provided above.

(b)After any such transfer, the transferring Holder shall retain its rights under this Agreement with respect to all other Registrable Securities owned by such transferring Holder.

(c)Upon the request of the transferring Holder, the Company shall execute an agreement with a Permitted Transferee substantially similar to this Agreement.

12.Miscellaneous.

(a)Specific Performance. In the event of any actual or threatened default in, or breach of, any of the terms, conditions and provisions of this Agreement, the party who is to be thereby aggrieved shall have the right to specific performance and injunctive or other equitable relief of their rights under this Agreement, in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies shall be cumulative. The parties agree that the remedies at law for any breach or threatened breach, including monetary damages, are inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at law would be adequate is waived. Any requirements for the securing or posting of any bond with such remedy are waived.

(b)Severability. If any term or other provision of this Agreement is determined by a nonappealable decision by a court, administrative agency or arbitrator to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the court, administrative agency or arbitrator shall interpret this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the fullest extent possible. If any sentence in this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only as broad as is enforceable.

(c)Further Assurances. Subject to the specific terms of this Agreement, each of the parties hereto shall make, execute, acknowledge and deliver such other instruments and documents, and take all such other actions, as may be reasonably required in order to effectuate the purposes of this Agreement and to consummate the transactions contemplated hereby.

(d)Failure or Indulgence not Waiver; Remedies Cumulative. No failure or delay on the part of either party in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor shall any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

(e)Entire Agreement. This Agreement, together with the Framework Agreement, contains the final and complete understanding of the parties with respect to its subject matter. This Agreement supersedes all prior agreements and understandings between the parties, whether written or oral, with respect to the subject matter hereof. Notwithstanding the foregoing, in the event of any conflict between the terms and provisions of this Agreement and those of the Framework Agreement, the terms of this Agreement shall control.

(f)No Third Party Beneficiaries. This Agreement is solely for the benefit of the parties and their respective Subsidiaries and is not intended to confer upon any other Person except the parties and their respective Subsidiaries any rights or remedies hereunder, and except for (i) any indemnified person under Section 8 and (ii) any Permitted Transferee.

(g)Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original but all of which shall constitute one and the same agreement.

(h)Termination. The right of any Holder to request registration or inclusion in any registration pursuant to this Agreement shall terminate on such date as all Registrable Securities held or entitled to be held upon conversion by such Holder and its Affiliates may immediately be sold under Rule 144 during any ninety (90) day period.

(i)Amendment. No change or amendment will be made to this Agreement except by an instrument in writing signed on behalf of each of the parties.

(j)Notices. Unless expressly provided herein, all notices, claims, certificates, requests, demands and other communications hereunder shall be in writing and shall be deemed to be duly given (i) when personally delivered or (ii) if sent by registered or certified mail, postage prepaid, return receipt requested, on the date the return receipt is executed or the letter refused by the addressee or its agent or (iii) if sent by overnight courier which delivers only upon the signed receipt of the addressee, on the date the receipt acknowledgment is executed or refused by the addressee or its agent or (iv) if sent by facsimile or other generally accepted means of electronic transmission, on the date confirmation of transmission is received (provided that a copy of any notice delivered pursuant to this clause (iv) shall also be sent pursuant to clause (ii) or (iii)), addressed as follows or sent by facsimile to the following number (or to such other address or facsimile number for a party as it shall have specified by like notice):

(i)if to the Company, to

(ii)if to a Holder of Registrable Securities, to the name and address as the same appear in the security transfer books of the Company,

or to such other address as either party (or other Holders of Registrable Securities) may, from time to time, designate in a written notice in a like manner.

(k)Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS THEREOF THAT WOULD RESULT IN THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION.

(l)Binding Effect; Assignment. This Agreement shall inure to the benefit of and be binding upon the parties and their respective legal representatives and successors. Except as specifically provided herein, and except that each Holder may assign any or all of its rights, interests and obligations hereunder to an Affiliate of such Holder, provided that any such Affiliate agrees in writing to be bound by all of the terms, conditions and provisions contained herein, this Agreement may not be assigned by either party.

(m)Preservation of Rights.

1. Services

1.1 Rosneft (the “Provider”) shall provide or procure the provision of (i) the Transitional Services; (ii) the Turnkey Services and Turnkey Materials; and (iii) the Operational Services and Operational Materials (together, the “Services” and the “Materials”, respectively) to NADL (the “Recipient”) or such members of the Recipient’s Group as the Recipient may direct.

2. Term

Transitional Services

2.14 The Provider shall provide or procure the provision of the Transitional Services for a period of 24 months from Completion (or for such other period as may be agreed between the Provider and the Recipient).

2.15 The Recipient may notify the Provider at any time during the 24 month period that certain Transitional Services (or certain components of a Transitional Service) are no longer required (the “Redundant Services”). Within 20 days of receipt of such notification, the Provider shall notify the Recipient (the “Increase Notice”) of any actual increase in the cost the Provider will incur (the “Actual Cost Increase”) as a result of the termination of the Redundant Services (the “Related Services”), and any adverse impact that it envisages on its ability to perform the Related Services (an “Adverse Impact”) as a result of the Redundant Services being terminated, and shall provide such information and evidence as the Recipient may reasonably require to evidence such increase and impact. The Provider shall use reasonable endeavours to mitigate the Actual Cost Increase as a result of the termination of the Redundant Services.

2.16 If the Recipient wishes to terminate the Redundant Services it may do so on 30 days’ written notice from the date on which the Increase Notice is required to be served under Paragraph 2.2, whereupon the Provider shall cease to provide or procure the provision of the Redundant Services and its charges shall be reduced accordingly. However, the Provider shall be entitled to increase its charges for the Related Services by the amount of the Actual Cost Increase (provided this shall not be more than the amount notified in the Increase Notice) plus such amount (not being greater than 5% of the Actual Cost Increase) as shall be necessary to comply with Russian transfer pricing regulations. The Provider shall not be liable to the Recipient for any Adverse Impact on the Related Services that results from termination of the Redundant Services.

Operational Services and Materials

2.17 The Provider shall provide or procure the provision of the Operational Services and Operational Materials in relation to each Onshore Drilling Contract for such period as the relevant Onshore Drilling Contracts remains in effect or, if shorter, for a period of 5 (five) years from the Completion Date.

2.18 The provisions of Paragraphs 2.2 and 2.3 above shall apply, mutatis mutandis, in relation to any Operational Services or Operational Materials (or components thereof) that the Recipient no longer requires during the period in which Operational Services or Operational Materials are being provided.

Turnkey Services and Materials

2.19 The Provider shall provide or procure the provision of the relevant Turnkey Services and Turnkey Materials in relation to each Turnkey Contract (in addition to the Operational Services and Operational Materials) for such period as the relevant contract remains a Turnkey Contract for the purposes of this Schedule.

2.20 The provisions of Paragraphs 2.2 and 2.3 above shall apply, mutatis mutandis, in relation to any Turnkey Services or Turnkey Materials (or components thereof) that the Recipient no longer requires during the period in which Turnkey Services or Turnkey Materials are being provided.

3. Service Levels

3.16 The Provider shall procure that the Services and Materials are provided with all reasonable skill and care on the terms and conditions set out in this Schedule and in the SLAs.

3.17 In the event of any conflict between this Schedule and the SLAs, including as to the term of any such arrangements, this Schedule shall prevail. The Provider and the Recipient respectively shall procure that members of the Retained Group and members of the Recipient’s Group give effect to the terms of this Schedule. The Provider shall procure that the Services and Materials shall be provided under this Schedule and (subject to the previous sentence) on the terms set out in the SLAs for the periods referred to in Paragraph 2 above notwithstanding the earlier expiry of any of the SLAs provided that if the Recipient’s Group is in material breach of its obligations under an SLA and such breach has not been remedied within a reasonable period of time, then the Provider shall be entitled to terminate the relevant SLA in accordance with its terms and shall not be liable to the Recipient as a result of such termination.

3.18 The Provider may amend some or all of the SLAs between the date of this Agreement and Completion in order to incorporate into such SLAs the terms of this Schedule, but shall not otherwise amend or terminate any SLA without the Recipient’s prior written consent.

3.19 If either the Provider or the Recipient can establish prior to Completion to the reasonable satisfaction of the other that the historic performance of the Retained Group under any SLA has been consistently higher or consistently lower than the standard required under the relevant SLA, the Provider and the Recipient shall discuss in good faith and make appropriate amendments to the relevant SLA to reflect the higher or lower historic standard of performance, PROVIDED THAT no such amendments shall be made to the extent they could reasonably be expected to compromise the Recipient’s Group’s ability to perform its contractual obligations under the Onshore Drilling Contracts or Turnkey Contracts or comply with applicable Russian law. The Provider shall, upon reasonable notice and subject to the receipt of such undertakings as to confidentiality as the Provider shall reasonably require, provide the Recipient with such information and access to books, records and employees of the Retained Group as the Recipient may reasonably request for the purpose of assessing historic performance levels and any differences between those levels and the standard of performance required under the SLAs provided that the provision of such information and access shall not cause undue disruption to the Provider’s business and activities.

3.20 The Provider and the Recipient agree that, to the extent that the Provider and the Recipient agree to make any changes to the Services and Materials and the terms on which they will be provided in accordance with this Schedule, the Recipient and the Provider shall procure that the SLAs shall be amended in order to incorporate into such SLAs any such changes.

4. Third Party Consents

Turnkey Services and Materials

5.39 The Provider shall be permitted to:

(A) outsource any components of the Services or Materials which are provided to the Sale Group and are not sourced from outside the Retained Group as at the date of this Agreement with the prior written consent of the Recipient (not to be unreasonably withheld or delayed);

(i) Rosneft shall notify NADL in writing promptly upon the outsourcing of such New Services (which notice shall include full details of any such New Services and the terms on which such New Services are provided);

(ii) no later than three Business Days prior to Completion, NADL shall notify Rosneft in writing whether it wishes such New Services (or any part of them) to be provided to the Sale Group following Completion;

(iii) if NADL does not serve a notice or notifies Rosneft that it does not wish the New Services (or any part of them) to be provided to the Sale Group following Completion, Rosneft shall terminate the relevant New Services on or before Completion and Rosneft shall ensure that such termination shall not result in any cost implications or any break fees, termination payments, penalties or other similar liabilities for NADL or the Sale Group; and/or

(C) transfer the provision of any components of the Services or Materials which are provided to the Sale Group and which are outsourced by the Retained Group as at the date of this Agreement to any other provider without the prior consent of the Recipient provided that any such change of provider does not result in a material change in the cost of such components or the quality of the service provided to the Sale Group.

5.40 The Provider shall procure that the allocation or apportionment of underlying costs between the Materials and Services provided to the Recipient’s Group on the one hand, and the other activities and operations to which such costs relate on the other hand, is done on a fair and proportionate basis and that the Recipient’s Group receives a fair and proportionate share of any rebates, refunds, credits or other benefits received by the Retained Group in respect thereof.

6.21 Neither the Recipient nor any member of the Recipient’s Group shall be liable for any breach of the Onshore Drilling Contracts to the extent that such liability is caused by, or attributable to, the Provider’s failure to provide or procure the provision of any of the Services or Materials or by any negligence or default of the Provider or any member of the Provider’s Group or any breach of applicable law (a “Provider Default”) and the Provider shall procure that no member of the Provider’s Group brings any claim against a member of the Recipient’s Group in respect of any loss, liability, cost, claim, matter or event to the extent caused by or attributable to a Provider Default.

Dear Sirs

1. We refer to the framework agreement (the "FrameworkAgreement") dated 20 August 2014 between Rosneft Oil Company ("Rosneft"), Seadrill Limited ("Seadrill") and North Atlantic Drilling Ltd. ("NADL" and together with Rosneft and Seadrill, the "Parties" and each a "Party") in relation to, inter alia, the issuance by NADL of a certain number of NADL shares to Rosneft in consideration of the transfer by Rosneft to NADL of the 100% participatory interest in limited liability company "RN Burenie" and the issuance by NADL of certain additional NADL shares to Rosneft in consideration of a cash payment.

2. In this letter, unless the context requires otherwise, terms defined in the Framework Agreement and not otherwise defined herein, shall have the same meanings in this letter. The principles of interpretation in Clause 1 (Interpretation) of the Framework Agreement shall also apply to this letter. References in the Framework Agreement to the “Agreement” and the “Key Agreements” include this letter and the Framework Agreement as amended by the terms of this letter.

3. In accordance with Clause 25.6 of the Framework Agreement, the Parties have agreed to vary the Framework Agreement on the terms of paragraph 4 of this letter. The provisions of Clauses 23 to 36 of the Framework Agreement shall apply to this letter as though incorporated herein mutatis mutandis.

4. The Parties agree that the Framework Agreement shall be amended as follows:

Timing

(A) the definition of the "Long Stop Date" in Clause 1.1 shall be deleted and replaced with:

""Long Stop Date" means 31 May 2015 (or such other date as the parties shall mutually agree);";

(B) Clause 10.1 shall be deleted and replaced with:

"10.1 Completion shall take place on the last Business Day of the month in which all of the Conditions shall have been satisfied or waived in accordance with this Agreement, but in any event, subject to Clause 7.1, Completion shall not take place any later than the Long Stop Date. The target date for Completion shall be 31 May 2015 (or such other date as the parties shall mutually agree).”;

(C) the following new clause shall be added to Clause 7:

“7.5A    Rosneft and NADL shall not, and shall procure that no party to any of the Service Orders shall, exercise after Completion any rights which it may have to serve notice under clause 13.3 of the Master Agreement.”

Break fees

(D) the following definitions in Clause 1.1 shall be deleted:

(i) "Intended Completion Date";

(v) "Rosneft Legal Opinions";

(vi) "Sanctions"; and

(E) the reference in the first sentence of Clause 7.7 to "but without prejudice to Clauses 6.13 to 6.18 (inclusive)" shall be deleted; and

(F) Clauses 6.13 to 6.18 (inclusive) shall be deleted.

5. We also refer to the master agreement in relation to each of the six Offshore Rigs dated 30 July 2014 (the "Master Agreement") between Rosneft and NADL. Rosneft and NADL agree that the 100 day period referred to in Clause 13.3 of the Master Agreement shall be extended to 31 May 2015 and, accordingly, Clause 13.3 shall have effect as follows:

"13.3    TERMINATION ON NOTICE

Either Contractor or Company may terminate a Service Order in its sole discretion without any liability to the other for any loss howsoever arising therefrom by giving at least fourteen (14) days' written notice to the other, such notice to be given by the earlier of (i) 31 May 2015, and (ii) the date of the passing of a resolution to approve the cooperation with NADL

at a duly convened and held general meeting of the shareholders of Rosneft (or by such later date as Contractor and Company may agree)."

6. The variations provided for in this letter shall, save where expressly provided to the contrary, come into force upon the countersignature of this letter by NADL and Seadrill. Other than as provided in: (i) paragraph 4 above, the Framework Agreement shall continue in full force and effect, and (ii) paragraph 5 above, the Master Agreement shall continue in full force and effect.

Dear Sirs,

1. We refer to the framework agreement (the "FrameworkAgreement") dated 20 August 2014 as amended on 7 November 2014 between Rosneft Oil Company ("Rosneft"), Seadrill Limited ("Seadrill") and North Atlantic Drilling Ltd. ("NADL" and together with Rosneft and Seadrill, the "Parties" and each a "Party") in relation to, inter alia, the issuance by NADL of a certain number of NADL shares to Rosneft in consideration of the transfer by Rosneft to NADL of the 100% participatory interest in limited liability company "RN Burenie" and the issuance by NADL of certain additional NADL shares to Rosneft in consideration of a cash payment.

2. In this letter, unless the context requires otherwise, terms defined in the Framework Agreement and not otherwise defined herein, shall have the same meanings in this letter. The principles of interpretation in Clause 1 (Interpretation) of the Framework Agreement shall also apply to this letter. References in the Framework Agreement to the “Agreement” and the “Key Agreements” include this letter and the Framework Agreement as amended by the terms of this letter and the letter dated 7 November 2014.

3. In accordance with Clause 25.6 of the Framework Agreement, the Parties have agreed to vary the Framework Agreement on the terms of paragraph 4 of this letter. The provisions of Clauses 23 to 36 of the Framework Agreement shall apply to this letter as though incorporated herein mutatis mutandis.

4. The Parties agree that the Framework Agreement shall be amended as follows:

Timing

(G) the definition of the "Long Stop Date" in Clause 1.1 shall be deleted and replaced with:

""Long Stop Date" means 31 May 2017 (or such other date as the parties shall mutually agree);";

(H) Clause 10.1 shall be deleted and replaced with:

"10.1 Completion shall take place on the last Business Day of the month in which all of the Conditions shall have been satisfied or waived in accordance with this Agreement, but in any event, subject to Clause 7.1, Completion shall not take place any later than the Long Stop Date. The target date for Completion shall be 31 May 2017 (or such other date as the parties shall mutually agree).”;

6. We also refer to the master agreement in relation to each of the six Offshore Rigs dated 30 July 2014 as amended on 7 November 2014 (the "Master Agreement") between Rosneft and NADL. The Parties acknowledge that the Service Orders for the West Navigator and Energy Endeavour Offshore Rigs have been terminated by Rosneft in accordance with Clause 13.3 of the Master Agreement. Rosneft and NADL agree that the 100 day period referred to in Clause 13.3 of the Master Agreement shall be extended to 31 May 2017 and, accordingly, Clause 13.3 shall have effect as follows:

"13.3    Termination on notice

Either Contractor or Company may terminate a Service Order in its sole discretion without any liability to the other for any loss howsoever arising therefrom by giving at least fourteen (14) days' written notice to the other, such notice to be given by the earlier of (i) 31 May 2017, and (ii) the date of the passing of a resolution to approve the cooperation with NADL at a duly convened and held general meeting of the shareholders of Rosneft (or by such later date as Contractor and Company may agree)."

6. The variations provided for in this letter shall, save where expressly provided to the contrary, come into force upon the countersignature of this letter by NADL and Seadrill. Other than as provided in: (i) paragraph 4 above, the Framework Agreement shall continue in full force and effect, and (ii) paragraph 5 above, the Master Agreement shall continue in full force and effect.

7. The Parties agree to use their reasonable endeavours to renegotiate not later than the Long Stop Date the characteristics of the Transaction and the terms of the Transaction Documents and the Offshore Drilling Contracts based on current macroeconomic indicators.

8. Notwithstanding the terms of the Framework Agreement, Master Agreement and Service Orders, the Parties agree that Seadrill and NADL (and the owners of the Offshore Rigs that remain subject to Service Orders (the "Remaining Offshore Rigs")) shall be entitled to (i) market the Remaining Offshore Rigs, (ii) enter into binding contracts with third parties in respect of the Remaining Offshore Rigs (iii) delay the mobilisation of the Remaining

Offshore Rigs in order to comply with the terms of any contracts with third parties, (iv) delay the construction and / or delivery of any of the Remaining Offshore Rigs, and (v) extend the construction period or shipyard stay of any of the Remaining Offshore Rigs.

9. Please confirm your agreement to the terms of this letter by countersigning below and returning one copy to us. This letter may be executed in any number of counterparts and by the Parties on separate counterparts, but shall not be effective unless each Party has executed at least one counterpart. Each counterpart shall constitute an original of this letter, but all the counterparts shall together constitute but one and the same instrument.

Yours faithfully,
