Each of RELX Capital Inc., a Delaware corporation (the “Issuer”), RELX PLC, a public limited company organized under the laws of England (“RELX PLC”), and RELX N.V., a public company incorporated in The Netherlands with limited liability (“RELX N.V.” and, together with RELX PLC, the “Guarantors”), confirms its agreement with each Underwriter named in Schedule 1 hereto (the “Underwriters”) with respect to the issuance and sale by the Issuer from the date hereof of $700,000,000 in aggregate principal amount of the Issuer’s 3.500% Notes due 2023 (the “Notes”). The Notes will be jointly and severally guaranteed (the “Guarantees”) by the Guarantors. Unless the context otherwise requires, all references herein to the Notes shall include the Guarantees.

The Notes will be issued under the Indenture dated as of May 9, 1995, among the Issuer, the Guarantors and The Bank of New York Mellon, as successor to JPMorgan Chase Bank, N.A. (formerly The Chase Manhattan Bank, N.A.), as trustee (the “Trustee”) (as amended and supplemented, the “Indenture”).

Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 6 of Form F-3 which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference. Certain terms used herein are defined in Section 22 hereof.

SECTION 1. REPRESENTATIONS AND WARRANTIES.

The Issuer, and each Guarantor (jointly and severally on behalf of each other and on behalf of the Issuer), represents and warrants to each Underwriter as of the date hereof and as of the Closing Date (as defined herein) as follows:

(a) General. The Issuer and the Guarantors have prepared and filed with the Commission an automatic shelf registration statement, as defined in Rule 405 (File No. 333-203608) on Form F-3, including a related Base Prospectus (the “Registration Statement”), for registration under the Act, of the offering and sale of the Notes. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing. The Issuer may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more preliminary prospectus supplements relating to the Notes, each of which has previously been furnished to you. The Issuer and the Guarantors will file with the Commission a final prospectus supplement relating to the Notes in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain all information required by the Act and the Rules and Regulations, and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Issuer has advised you, prior to the Execution Time, will be included or made therein. The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x).

(b) Registration Statement, Final Prospectus and Indenture. On the Effective Date, the Registration Statement did, and when the Final Prospectus is first filed in accordance with Rule 424(b) and on the Closing Date (as defined herein), the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act, the Exchange Act and the Trust Indenture Act and the respective rules thereunder; on the Effective Date, the Registration Statement did not contain any untrue statement of a material fact or omit to state any material fact required

to be stated therein or necessary in order to make the statements therein not misleading; on the Effective Date and on the Closing Date the Indenture did or will comply in all material respects with the applicable requirements of the Trust Indenture Act and the rules thereunder; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date, the Final Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Issuer makes no representations or warranties as to (i) that part of the Registration Statement which shall constitute the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act of the Trustee or (ii) the information contained in or omitted from the Registration Statement or the Final Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Issuer or any of the Guarantors by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Registration Statement or the Final Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 7 hereof.

(d) Well-Known Seasoned Issuer. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Issuer or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Notes in reliance on the exemption in Rule 163, and (iv) at the Execution Time (with such date being used as the determination date for purposes of this clause (iv)), the Issuer was or is (as the case may be) a “well-known seasoned issuer” as defined in Rule 405.

SECTION 7. INDEMNIFICATION AND CONTRIBUTION.

(a) The Issuer and the Guarantors, jointly and severally, shall indemnify and hold harmless each Underwriter, its affiliates and the directors, officers, employees and agents of each Underwriter and its affiliates and each person, if any, who controls any Underwriter within the meaning of either the Act or the Exchange Act from and against any loss, claim, damage or liability, joint or several, and any action in respect thereof, to which they or any of them may become subject, under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Notes as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Notes, the Final Prospectus, any Issuer Free Writing Prospectus, including but not limited to any electronic road show that is a “written communication” within the meaning of Rule 433(d)(8)(i), or the information contained in the final term sheet required to be prepared and filed pursuant to Section 2(c) hereto, or in any amendment thereof or supplement thereto, or arises out of, or is based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading and shall reimburse each such indemnified person for any legal and other expenses reasonably incurred by such indemnified person in investigating or defending or preparing to defend

against any such loss, claim, damage, liability or action, as such expenses are incurred; provided, however, that the Issuer and the Guarantors shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Issuer or any of the Guarantors by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. The Issuer acknowledges that the statements set forth in the fourth, eighth, ninth and tenth paragraphs under the caption “Underwriting” in the Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus. The foregoing indemnity agreement is in addition to any liability which the Issuer or the Guarantors may otherwise have to any Underwriter or any controlling person of any Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Issuer and the Guarantors, each of their respective directors, employees, each of the officers who signed the Registration Statement, any person, if any, who controls any of the Issuer or the Guarantors within the meaning of the Act or the Exchange Act, the U.S. authorized representative of the Guarantors and any person nominated to become a director of the Issuer who signed a consent filed with the Registration Statement from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which an Issuer or Guarantor or any such controlling person may become subject under the Act, the Exchange Act, federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Notes as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Notes, the Final Prospectus, any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 2(c) hereto, or in any amendment thereof or supplement thereto, or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the same extent as the foregoing indemnity from the Issuer to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Issuer or the Guarantors by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. The Issuer acknowledges that the statements set forth in the fourth, eighth, ninth and tenth paragraphs under the caption “Underwriting” in the Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Disclosure Package, the Final Prospectus, any Issuer Free Writing Prospectus.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) of this Section 7 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) of this Section 7, notify the indemnifying party in writing of the claim or the commencement of the action; provided that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the extent it has been materially prejudiced by such failure and, provided further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7. If any such claim or action shall be brought against an indemnified party, and it shall notify 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 satisfactory to 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 7 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 any indemnified party shall have the right to retain its own counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate counsel (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the relevant Underwriter or Underwriters in the case of parties indemnified pursuant to paragraph (a) above and by the Issuer and the Guarantors in the case of parties indemnified pursuant to paragraph (b) above. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 7, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of such request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in

respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include an admission of fault.

(d) If the indemnification provided for in this Section 7 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or 7(b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, 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, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Issuer and the Guarantors on the one hand and the relevant Underwriter on the other from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or for any reason, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuer and the Guarantors on the one hand and such Underwriter on the other with respect to the statements or omissions or actions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Issuer and the Guarantors on the one hand and an Underwriter on the other with respect to the offering of Notes shall be deemed to be in the same proportion as the net proceeds from such offering (before deducting expenses) received by the Issuer on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes under this Agreement, in each case as set forth in the table on the cover page of the Final Prospectus. 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 supplied by the Issuer or the Guarantors on the one hand or the Underwriter, on the other, the intent of the parties and their respective knowledge, access to information and opportunity to correct or prevent such statement or omission. For purposes of the preceding two sentences, the net proceeds deemed to be received by the Issuer shall be deemed to be also for the benefit of the Guarantors and information supplied by the Issuer shall also be deemed to have been supplied by the Guarantors. The Issuer, the Guarantors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. 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 Section 7 shall be deemed to include, for purposes of this Section 7, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this ▇▇▇▇▇▇▇ ▇, ▇▇▇▇ of the Underwriters shall be responsible for any amount in excess of the underwriting discount or commission applicable to the Notes purchased by such Underwriter hereunder. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 7(d) are several in proportion to their respective underwriting obligations and not joint.

SECTION 8. REPRESENTATIONS, WARRANTIES AND OBLIGATIONS TO SURVIVE DELIVERY.

The respective indemnities, agreements, representations, warranties and other statements of the Issuer and the Guarantors and the Underwriters contained in this Agreement, or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or any officer, director, employee or any person controlling such Underwriter or by or on behalf of the Issuer and the Guarantors or any person controlling the Issuer or the Guarantors, and shall survive each delivery of and payment for any of the Notes. The provisions of Sections 7 and 12 shall survive the termination or cancellation of this Agreement.

SECTION 9. [RESERVED.]

SECTION 10. TERMINATION.

The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Issuer prior to delivery of and payment for the Notes, if, prior to that time, any of the events described in Sections 6(c) or 6(l) shall have occurred or if the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement.

SECTION 11. DEFAULTING UNDERWRITERS.

If, on the Closing Date, any Underwriter defaults in the performance of its obligations to purchase the Notes under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Notes which the defaulting Underwriter agreed but failed to purchase on the Closing Date in the respective proportions which the principal amount of Notes set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the aggregate principal amount of Notes set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Notes on the Closing Date if the aggregate principal amount of the Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the Notes to be purchased on the Closing Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the principal amount of Notes which it agreed to purchase on the Closing Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Notes to be purchased on the Closing Date. If the remaining Underwriters or other

underwriters satisfactory to the Representatives do not elect to purchase the Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase on the Closing Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Issuer or either Guarantor, except that the Issuer and the Guarantors will continue to be liable for the payment of expenses to the extent set forth in Section 5. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 11, purchases Notes which a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Issuer or any Guarantor or any non-defaulting Underwriter for damages caused by its default. If other underwriters are obligated or agree to purchase the Notes of a defaulting or withdrawing Underwriter, either the Representatives or the Issuer may postpone the Closing Date for up to seven full Business Days in order to effect any changes that in the opinion of counsel for the Issuer and the Guarantors or counsel for the Underwriters may be necessary in any Registration Statement, the Prospectus or in any other document or arrangement.

SECTION 12. REIMBURSEMENT OF UNDERWRITERS’ EXPENSES.

If the Issuer shall fail to tender the Notes and Guarantees for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Issuer or any Guarantor to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Issuer or any Guarantor is not fulfilled (other than by reason of any event described in Section 6(l), except for the suspension of trading or minimum prices of the securities of the Issuer or either Guarantor or for an event referred to in clause (i) of such section), the Issuer and the Guarantors, jointly and severally, will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Notes, and promptly following receipt of an invoice the Issuer and the Guarantors, jointly and severally, shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 11 by reason of the default of one or more Underwriters, neither the Issuer nor any Guarantor shall be obligated to reimburse any defaulting Underwriter on account of those expenses.

Notwithstanding anything to the contrary herein, each Underwriter agrees (without prejudicing any claim it may have against the Issuer or either Guarantor), at its own expense, to pay the portion of all expenses not reimbursed by the Issuer and the Guarantors pursuant to this Section 12 hereof represented by such Underwriter’s pro rata share (based on the principal amount of Notes that such Underwriter agreed to purchase hereunder) of the Notes.
