as Representatives of the

several Underwriters named

in Schedule II hereto

Ladies and Gentlemen:

GlaxoSmithKline plc, a public limited company incorporated in England and Wales (the “Company”), proposes to sell to the several underwriters named in Schedule II hereto (the “Underwriters”), for whom you (the “Representatives”) are acting as representatives, the principal amount of its securities identified in Schedule I hereto (the “Securities”), to be issued under an indenture dated as of March 4, 2008 (as amended, modified or supplemented by the First Supplemental Indenture dated as of March 21, 2014, the “Indenture”), between the Company and Law Debenture Trust Company of New York, as trustee (the “Trustee”).

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 that were filed under the U.S. Securities Exchange Act of 1934, as amended, and the rules and regulations of the U.S. Securities and Exchange Commission (the “Commission”) thereunder (collectively, 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 19 hereof.

1. Representations and Warranties. The Company represents and warrants to, and agrees with, each Underwriter as follows:

(a) Registration Statement Effective. The Company meets the requirements for use of Form F-3 under the U.S. Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”) and has filed with the Commission an automatic shelf registration statement, as defined in Rule 405 (No. 333-[ ]) on Form F-3, including a related Base Prospectus, for registration under the Securities Act of the offering and sale from time to time of

certain debt securities, including the Securities. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing. The Company 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 Securities, each of which will have previously been furnished to you. The Company will file with the Commission a final prospectus supplement relating to the Securities in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain all information required by the Securities Act, 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 Company 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). No stop order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose has been instituted or, to the knowledge of the Company, threatened by the Commission.

(b) Registration Statement Not Misleading. On each Effective Date, the Registration Statement complied in all material respects with the applicable requirements of the Securities Act; on each Effective Date and at the Execution Time, 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; and on its date as reflected in any filing pursuant to Rule 424(b) under the Securities Act and on the Closing Date (as defined below), 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 Company makes no representation or warranty as to (i) the Statement of Eligibility and Qualification of the Trustee under the Trust Indenture Act (Form T-1), which is included in the Registration Statement, 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 Company 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 8 hereof.

(c) Disclosure Package. At the Execution Time, (i) the Disclosure Package and (ii) each electronic road show, if any, when taken together as a whole with the Disclosure Package, do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for

use therein, 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 8 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 Securities 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) and (iii) at the time the Company or any person acting on their behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption in Rule 163, the Company was or is (as the case may be) a “well-known seasoned issuer” as defined in Rule 405. The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(e) Not an Ineligible Issuer. (i) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Securities and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii) the Company was not and is not an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary to consider whether the Company would be considered an Ineligible Issuer.

(f) Issuer Free Writing Prospectus. Each Issuer Free Writing Prospectus (including the final term sheet prepared and filed pursuant to Section 5(c) hereof) does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein by reference and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, 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 8 hereof.

(g) Authorization of Indenture and Securities. The Indenture has been duly authorized, executed and delivered by the Company and has been duly qualified under the U.S. Trust Indenture Act of 1939, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Trust Indenture Act”); the Securities have been duly authorized by the Company, and when the Securities are delivered and paid for pursuant to this Agreement on the Closing Date, the Securities will have been duly executed, authenticated, issued and delivered and will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity; and, when the Securities have been duly executed, authenticated, issued and delivered, the Securities will conform in all material respects to the description thereof contained in the Disclosure Package and the Final Prospectus.

(h) Organization of the Company. The Company is organized and validly existing as a public limited company under the laws of England and Wales, with power and authority to own its properties and conduct its business as described in the Disclosure Package and the Final Prospectus.

(i) No Consents. No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required for the consummation by the Company of the transactions contemplated by this Agreement in connection with the issuance and sale of the Securities by the Company, except such as have been obtained or made under the Securities Act, the Exchange Act and the Trust Indenture Act and such as may be required under state securities laws or the securities laws of any jurisdiction outside the United States in which the Securities are offered and sold.

(j) No Breach or Default. The execution, delivery and performance by the Company of the Indenture, this Agreement and the issuance and sale of the Securities and compliance with the terms and provisions thereof by the Company will not result in a breach or violation of any of the terms and provisions of, or constitute a default under (i) any law or regulation of the jurisdiction of incorporation of the Company, (ii) any material agreement or instrument to which the Company or any of the Company’s subsidiaries is a party or by which the Company or the Company’s subsidiaries is bound or to which any of their respective properties is subject, or (iii) the charter or by-laws of the Company, except in the cases of clauses (i) and (ii) above for such breaches, violations or defaults that would not affect the validity, binding nature or enforceability of the Indenture or the Securities or have a material adverse effect on the financial condition, earnings, business or properties of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business.

(k) Investment Company Act. The Company is not, nor, after giving effect to the offering and sale of the Securities and the application of the proceeds therefrom as described in the Disclosure Package and the Final Prospectus, will be an “investment company” as defined in the U.S. Investment Company Act of 1940, as amended.

(l) Disclosure Controls. The Company and its subsidiaries maintain “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures are effective.

Any certificate signed by any officer of the Company and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Securities shall be deemed a representation and warranty by the Company, as to matters covered thereby, to each Underwriter.

2. Purchase and Sale. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at the purchase price set forth in Schedule I hereto the principal amount of the Securities set forth opposite such Underwriter’s name in Schedule II hereto.

3. Delivery and Payment. Delivery of and payment for the Securities shall be made on the date and at the time specified in Schedule I hereto or on such other date and at such other time as the Company and the Representatives may agree (such date and time of delivery and payment for the Securities being herein called the “Closing Date”).

Delivery of the Securities shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company.

4. Payment of Expenses. The Company agrees to pay or cause to be paid the following: (i) except as provided in the proviso contained in Section 5(g) hereof, the fees, disbursements and expenses of counsel and accountants of the Company in connection with the registration of the Securities under the Securities Act and the qualification of any indenture related to the Securities under the Trust Indenture Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus and amendments and supplements thereto, the Disclosure Package and any Issuer Free Writing Prospectus and the mailing and delivering of copies thereof to the Underwriters; (ii) the cost of printing or producing this Agreement, the Disclosure Package, any indenture related to the Securities, any Blue Sky and legal investment memoranda and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) any fees charged by securities rating services for rating the Securities; (iv) any filing fees incident to any required review by the Financial Industry Regulatory Authority, Inc. of the terms of the sale of the Securities; (v) the cost of preparing the Securities and of the delivery of the Securities to the Underwriters; (vi) the reasonable fees and expenses of any Trustee and any agent of any Trustee and the reasonable fees and disbursements of counsel for any Trustee in connection with the Indenture and the Securities; and (vii) except as provided in the proviso contained in Section 5(g) hereof, all other reasonable costs and expenses incident to the performance of their obligations hereunder which are not otherwise specifically provided for in this Section.

5. Agreements. The Company agrees with the several Underwriters as follows:

(a) File Prospectus. The Company will file the Final Prospectus with the Commission pursuant to and in accordance with Rule 424(b) under the Securities Act within the time period prescribed.

(b) Amendments to Registration Statement or Prospectus; Stop Orders. The Company will advise the Representatives promptly of any proposal to amend the Registration Statement or file any supplement (including the Final Prospectus or any Preliminary Prospectus) to the Base Prospectus and will afford the Representatives a reasonable opportunity to comment on any such proposed amendment or supplement. The Company will promptly advise the Representatives of the filing of any such amendment or supplement and of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose. The Company will use its reasonable best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) Final Term Sheet. The Company will prepare a final term sheet, containing solely a description of final terms of the Securities and the offering thereof, in the form approved by you and attached as Schedule IV hereto and to file such term sheet pursuant to Rule 433(d) within the time required by such Rule.

(d) Amendment of Disclosure Package. If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Company will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(e) Material Changes. If, at any time when a prospectus relating to the Securities is required to be delivered under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Final Prospectus to comply with the Securities Act or the Exchange Act, the Company will promptly notify the Representatives of such event and prepare and file with the Commission an amendment or supplement that will correct such statement or omission or effect such compliance.

(g) Delivery of Registration Statement and Prospectus. The Company will furnish to the Representatives copies of the Registration Statement and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement to any of the foregoing as the Representatives may reasonably request. The Company will pay the expenses of preparation, printing or other production of all documents relating to the offering; provided that, if any Underwriter is required to deliver a Final Prospectus in connection with sales of Securities at any time six months or more after the date of the Final Prospectus, the expenses relating to such Final Prospectus shall be paid by such Underwriter.

(h) Qualification of Securities. The Company will use its reasonable best efforts to arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may reasonably designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the Financial Industry Regulatory Authority, Inc. in connection with its review of the offering; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified, to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject or to subject itself to taxation as doing business in any such jurisdiction.

(i) No Other Offering Materials. The Company agrees that, unless it has or shall have obtained the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has or shall have obtained, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433, other than a free writing prospectus containing the information contained in the final term sheet prepared and filed pursuant to Section 5(c) hereof; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III hereto and any electronic road show. Any such free writing prospectus consented to by the Representatives and the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(j) Lock-up. The Company will not, without the prior written consent of the Representatives, which consent shall not be unreasonably withheld, offer, sell, contract to sell, pledge, or otherwise dispose of, directly or indirectly, including the filing (or

participation in the filing) of a registration statement with the Commission in respect of, any U.S. dollar-denominated debt securities issued or guaranteed by the Company (other than the Securities), which mature more than one year after the Closing Date and which are substantially similar to the Securities, until the Business Day set forth on Schedule I hereto.

(k) Stabilization. The Company will not take, directly or indirectly, any action that is designed to or that constitutes, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(l) Listing. The Company will use reasonable best efforts to have the Securities listed and admitted to trading on the [ ] Stock Exchange or another “recognised stock exchange” (as defined in Section 1005 of the United Kingdom Income Tax Act 2007), and satisfactory evidence of such actions shall have been provided to the Representatives.

6. Conditions to the Obligations of the Underwriters. The obligations of the Underwriters to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Execution Time and as of the Closing Date, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

Registration Statement, the Disclosure Package and the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(e) Certificate of the Company. The Company shall have furnished to the Representatives, on behalf of the Underwriters, a certificate of officers of the Company reasonably satisfactory to the Representatives, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Disclosure Package, the Final Prospectus and any supplements or amendments thereto, as well as each electronic road show used in connection with the offering of the Securities, and this Agreement and that:

(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to the knowledge of the Company, threatened; and

(iii) since the date of the most recent financial statements included or incorporated by reference in the Disclosure Package and the Final Prospectus (in each case, exclusive of any supplement thereto after the date hereof), there has been no material adverse effect or any development which in the reasonable judgment of the Company will result in any material adverse effect on the financial condition, earnings, business or properties of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (in each case, exclusive of any supplement thereto after the date hereof) or as described in such certificate.

(f) Accountants’ Comfort Letters. The Company shall have requested and caused PricewaterhouseCoopers LLP to have furnished to the Representatives, on behalf of the Underwriters, at the Execution Time and on the Closing Date, letters (which may refer to letters previously delivered to one or more of the Representatives), dated respectively as of the date hereof and as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they are independent accountants within the meaning of the Securities Act and the Exchange Act stating in effect, that:

(i) in their opinion the audited financial statements and financial statement schedules, if any, included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus and reported on by them comply as to form in all material respects with the applicable accounting requirements of the Securities Act and the Exchange Act;

(ii) on the basis of a reading of the latest unaudited financial statements made available by the Company and its subsidiaries; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards), which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the stockholders, directors and audit committee of the Company; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its subsidiaries as to transactions and events subsequent to [ ], nothing came to their attention, after due inquiry, that caused them to believe that:

(1) any unaudited financial statements included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus;

(2) with respect to the period subsequent to December 31, 20[ ], there were any changes (provided that the requested information was available in response to such inquiry), at a specified date not more than five days prior to the date of the letter, in the long-term debt of the Company and its subsidiaries or capital stock of the Company as compared with the amounts shown on the December 31, 20[ ] consolidated balance sheet included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus, except in each instance for changes or decreases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is not deemed necessary by the Representatives; or

(3) the information included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus in response to Form 20-F, Item 3.A. (Selected Financial Data) and Regulation S-K, Item 503(d) (Ratio of Earnings to Fixed Charges) is not in conformity with the applicable disclosure requirements of Form 20-F and Regulation S-K, respectively; and

(iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company and its subsidiaries) set forth in the Registration Statement, the Preliminary Prospectus and the Final Prospectus, including the information set forth under the captions “Ratios of Earnings to Fixed Charges” in the Preliminary Prospectus and the Final Prospectus, the information included or incorporated by reference in Items 3, 4, 5 and 6 of the Company’s Annual Report on Form 20-F, incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus, agrees with the accounting records of the Company and its subsidiaries, excluding any questions of legal interpretation.

(g) No Material Adverse Change. Subsequent to the Execution Time, there shall not have been (i) any change, or any development which in the reasonable judgment of the Company will result in any change, in or affecting the financial condition, earnings, business or properties of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (in each case, exclusive of any supplement thereto after the date hereof) or (ii) any decrease in the rating of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g)) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change, the effect of which, in any case referred to in clause (i) or (ii) above, is, in the judgment of a majority in interest of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement, the Disclosure Package and the Final Prospectus (in each case, exclusive of any supplement thereto after the date hereof).

The Representatives may in their sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters under this Agreement.

The documents required to be delivered by this Section 6 shall be delivered at the office of Sidley Austin LLP, counsel for the Underwriters, at 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000 or 00 Xxxxxxxxxx Xxxxxx, Xxxxxx XX0X 0XX, Xxxxxx Xxxxxxx, on the Closing Date.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representatives on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been reasonably incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution.

(a) Indemnification of the Underwriters by the Company. The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or

actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement 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 Securities, the Final Prospectus, or any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(c) hereof, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability 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 Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) Indemnification of the Company by the Underwriters. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability that any Underwriter may otherwise have. The Company acknowledges that the statements set forth in [ ] constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus.

(c) Actions Against Parties; Notification. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and

expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ a single separate counsel, and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel, if the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest. An indemnifying party shall not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. The indemnifying party shall not be liable for any settlement of any such action, suit or proceeding effected without its written consent.

(d) Contribution. In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the relative intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable

considerations referred to above. Notwithstanding the provisions of this paragraph (d), 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. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities that the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities that the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if arrangements satisfactory to the Representatives and the Company for the purchase of such Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Company’s Common Stock shall have been suspended by the London Stock Exchange or trading in the Company’s American Depositary Shares shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange or the London Stock Exchange shall have been suspended or materially limited, (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the reasonable judgment of the Representatives, after consultation with the Company, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by any Preliminary Prospectus or the Final Prospectus (in each case, exclusive of any amendment or supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement shall remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and shall survive delivery of and payment for the Securities. The provisions of Sections 7, 8, 14 and 18 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder shall be in writing and effective only on receipt, and, (i) if sent to the Representatives, shall be mailed, delivered or telefaxed to [ ] attention:[ ] or, (ii) if sent to the Company, shall be mailed, delivered or telefaxed to 000 Xxxxx Xxxx Xxxx, Xxxxxxxxx, Xxxxxxxxx, XX0 0XX, Xxxxxxx, facsimile: 00 (0) 000 000 0000, attention: The Company Secretary.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

15. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.

16. Headings. The section headings used herein are for convenience only and shall not affect the construction hereof.

17. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters and any affiliate through which any of them may be acting, on the other hand, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company and (c) the Company’s engagements of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect in connection with the offering of the Securities, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

18. Consent to Jurisdiction; Appointment of Agent to Accept Service of Process.

(a) The Company irrevocably consents and agrees that any legal action, suit or proceeding against it with respect to any matter arising out of or based upon this Agreement may be brought in the courts of the State of New York located in The City of New York or the courts of the United States of America located in The City of New York and hereby irrevocably consents and submits to the non-exclusive jurisdiction of each such court in personam, generally and unconditionally with respect to any such action, suit or proceeding.

(b) The Company hereby irrevocably designates, appoints, and empowers the [ ], with offices currently at [ ], as its designee, appointee and agent to receive, accept and acknowledge for and on its behalf, service of any and all legal process, summons, notices and documents that may be served in any action, suit or proceeding brought against the Company in any such United States or State court with respect to any matter arising out of or based upon this Agreement and that may be made on such designee, appointee and agent in accordance with legal procedures prescribed for such courts. The Company further hereby irrevocably consents and agrees to the service of any and all legal process, summons, notices and documents in any such action, suit or proceeding against it by serving a copy thereof upon the relevant agent for service of process referred to in this Section 18 (whether or not the appointment of such agent shall for any reason prove to be ineffective or such agent shall accept or acknowledge such service). The Company agrees that the failure of any such designee, appointee and agent to give any notice of such service to it shall not impair or affect in any way the validity of such service or any judgment rendered in any such action or proceeding based thereon. Nothing herein shall in any way be deemed to limit the ability of the Underwriters to serve such legal process, summons, notices and documents in any other manner permitted by applicable law or to obtain jurisdiction over the Company or bring actions, suits or proceedings against the Company in such other jurisdictions, and in such manner, as may be permitted by applicable law. The Company hereby irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of venue of any of the aforesaid actions, suits or proceedings arising out of or based upon this Agreement brought in the United States federal courts located in The City of New York or the courts of the State of New York located in The City of New York and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

as Representatives of the several Underwriters

c/o [ ]

Ladies and Gentlemen:

We have acted as special United States counsel to GlaxoSmithKline plc, a public limited company incorporated in England and Wales (the “Company”) in connection with the offering from time to time, together or separately and in one or more series, pursuant to a registration statement on Form F-3 (No. 333-[ ]) of debt securities of the Company (the “Debt Securities”) to be issued under an indenture dated as of March 4, 2008, as supplemented by the First Supplemental Indenture dated as of March 21, 2014, (the “Indenture”) between the Company and Law Debenture Trust Company of New York, as trustee (the “Trustee”). Such registration statement, as amended as of its most recent effective date ([ ], 20[ ]), insofar as it relates to the Debt Securities (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)), but excluding the documents incorporated by reference therein, is herein called the “Registration Statement;” the related prospectus dated [ ], 20[ ], included in the Registration Statement filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Base Prospectus;” the preliminary prospectus supplement dated [ ], 20[ ], as filed with the Commission pursuant to Rule 424(b) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Preliminary Prospectus Supplement;” and the related prospectus supplement dated [ ], 20[ ], as filed with the Commission pursuant to Rule 424(b) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Final Prospectus Supplement.” The Base Prospectus and the Preliminary Prospectus Supplement together are herein called the “Pricing Prospectus,” and the Base Prospectus and the Final Prospectus Supplement together are herein called the “Final Prospectus.” This opinion letter is furnished pursuant to Section 6(b) of the underwriting agreement dated [ ], 20[ ] (the “Underwriting Agreement”) between the Company and the several underwriters named in Schedule II thereto (the “Underwriters”).

In arriving at the opinions expressed below, we have reviewed the following documents:

(a) an executed copy of the Underwriting Agreement;

A-1-1

(b) the Registration Statement and the documents incorporated by reference therein;

(c) the Pricing Prospectus, the documents incorporated by reference therein [and the documents listed in Schedule I hereto];

(d) the Final Prospectus and the documents incorporated by reference therein;

(e) [a facsimile copy of] the Debt Securities in global form as executed by the Company and authenticated by the Trustee;

(f) an executed copy of the Indenture, including the certificated form of Debt Securities; and

(g) the documents delivered to you by the Company at the closing pursuant to the Underwriting Agreement.

In addition, we have reviewed the originals or copies certified or otherwise identified to our satisfaction of all such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinions expressed below.

In rendering the opinions expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified (i) the accuracy as to factual matters of each document we have reviewed (including, without limitation, the accuracy of the representations and warranties of the Company in the Underwriting Agreement) and (ii) that any Debt Securities in certificated form issued in exchange for the Debt Securities in global form will conform to the form thereof that we have reviewed and will be duly authenticated in accordance with the terms of the Indenture.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that:

1. The Indenture has been duly executed and delivered by the Company under the law of the State of New York and has been qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and is a valid, binding and enforceable agreement of the Company.

2.(a) (i) The Debt Securities in global form have been duly executed and delivered by the Company under the law of the State of New York and are, and (ii) the Debt Securities in certificated form when exchanged for interests in the Debt Securities in global form in accordance with the terms thereof and of the Indenture will be, the valid, binding and enforceable obligations of the Company and entitled to the benefits of the Indenture.

3. The statements under the heading “Description of the Notes” in the Pricing Prospectus, considered together with the documents listed in Schedule I hereto, and in the Final Prospectus, together in each case with the statements under the heading “Description of Debt Securities” in the Base Prospectus, insofar as such statements purport to summarize certain provisions of the Debt Securities and the Indenture, provide a fair summary of such provisions.

A-1-2

4. The Underwriting Agreement has been duly executed and delivered by the Company under the law of the State of New York.

5. The issuance and sale of the Debt Securities to the Underwriters pursuant to the Underwriting Agreement do not, and the performance by the Company of its obligations in the Underwriting Agreement, the Indenture and the Debt Securities, respectively, will not, require any consent, approval, authorization, registration or qualification of or with any governmental authority of the United States or the State of New York that in our experience normally would be applicable to general business entities with respect to such issuance, sale or performance, except such as have been obtained or effected under the Securities Act, the Securities Exchange Act of 1934, as amended, and the Trust Indenture Act (but we express no opinion relating to any state securities or Blue Sky laws).

6. No registration of the Company under the Investment Company Act of 1940, as amended, is required for the offer and sale of the Debt Securities by the Company in the manner contemplated by the Underwriting Agreement and the Final Prospectus.

Insofar as the foregoing opinions relate to the validity, binding effect or enforceability of any agreement or obligation of the Company, (a) we have assumed that the Company and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to the Company regarding matters of the federal law of the United States of America or the law of the State of New York that in our experience normally would be applicable to general business entities with respect to such agreement or obligation), (b) such opinions are subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity and (c) such opinions are subject to the effect of judicial application of foreign laws or foreign governmental actions affecting creditors’ rights.

The waiver of defenses contained in Section 6.01 of the Indenture may be ineffective to the extent that any such defense involves a matter of public policy in New York (such as reflected in New York’s anti-champerty statute). With respect to Section 18 of the Underwriting Agreement, we express no opinion as to the subject matter jurisdiction of any United States federal court to adjudicate any action relating to the Underwriting Agreement where jurisdiction is based on diversity of citizenship under 28 U.S.C. § 1332 does not exist. We express no opinion as to the enforceability of Section 11.15 of the Indenture relating to currency indemnity.

The foregoing opinions are limited to the federal law of the United States of America and the law of the State of New York.

We are furnishing this opinion letter to you, as Representatives of the Underwriters, solely for the benefit of the Underwriters in their capacity as such in connection with the offering of the Debt Securities. This opinion letter is not to be relied on by or furnished to any other person or used, circulated, quoted or otherwise referred to for any other purpose, except that this opinion letter may be relied upon by the Trustee in its capacity as such. We assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinions expressed herein.

Ladies and Gentlemen:

We have acted as special English counsel to GlaxoSmithKline plc, a public limited company incorporated in England and Wales (the “Company”), in connection with the offering pursuant to a registration statement on Form F-3 (No. 333-[ ]) of debt securities of the Company (the “Debt Securities”) to be issued under an indenture dated as of March 4, 2008, as supplemented by the First Supplemental Indenture dated as of March 21, 2014 (the “Indenture”) between the Company and Law Debenture Trust Company of New York, as trustee (the “Trustee”). Such registration statement, as amended as of its most recent effective date ([ ], 20[ ]), insofar as it relates to the Debt Securities (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)), but excluding the documents incorporated by reference therein, is herein called the “Registration Statement;” the related prospectus dated [ ], 20[ ], included in the Registration Statement filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Base Prospectus;” the preliminary prospectus supplement dated [ ], 20[ ], as filed with the Commission pursuant to Rule 424(b) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Preliminary Prospectus Supplement;” and the related prospectus supplement dated [ ], 20[ ], as filed with the Commission pursuant to Rule 424(b) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Final Prospectus Supplement.” The Base Prospectus and the Preliminary Prospectus Supplement together are herein called the “Pricing Prospectus,” and the Base Prospectus and the Final Prospectus Supplement together are herein called the “Final Prospectus.” This opinion letter is furnished pursuant to Section 6(b) of the underwriting agreement dated [ ], 20[ ] (the “Underwriting Agreement”) between the Company and the several underwriters named in Schedule II thereto (the “Underwriters”).

We understand that the Debt Securities are not and are not intended to be admitted to trading on any market or exchange, or otherwise listed, in the United Kingdom.

Unless defined herein, capitalised terms have the meanings attributed to them in the Underwriting Agreement.

In this opinion letter, the Underwriting Agreement, the Indenture and the Debt Securities are referred to collectively as the “Transaction Documents” or each individually as a “Transaction Document.”

In rendering the opinions expressed below we have assumed and not verified:

(a)

the genuineness of all signatures, stamps and seals, the authenticity and completeness of all documents supplied to us and the conformity to the originals of all documents supplied to us as photocopies, facsimile or electronic copies;

(b)

that, where a document has been examined by us in draft, specimen or certificated form, it has been or will be executed in the form of that draft, specimen or certificate, and in the case of Debt Securities, that they have been or will be authenticated in accordance with the terms of the Indenture;

A-2-2

(c)

that each of the Transaction Documents has been or will be duly authorised, executed and delivered by or on behalf of each of the parties to such Transaction Document (other than the Company) and each such party (other than the Company) has the power, capacity and authority to execute, deliver and perform its obligations contained in each of the Transaction Documents to which it is a party;

(f)

that none of the execution of the Indenture or the Underwriting Agreement, the issue of the Debt Securities, the performance of the respective obligations of each of the parties thereto and the application of the proceeds of the issue of the Debt Securities constitutes financial assistance prohibited by Section 678 of the Companies Xxx 0000;

that each of the Transaction Documents constitutes legal, valid and binding obligations of the parties thereto under all applicable laws (including the laws of the State of New York by which the Transaction Documents are expressed to be governed) enforceable in accordance with their terms and have the same meaning and effect as if they were governed by English law;

(h)

that the information relating to the Company disclosed by our on-line searches on [ ], 20[ ], at Companies House and by telephone at the Central Registry of Winding up Petitions at the Companies Court in London on [ ], 20[ ], in relation to the Company was then complete, up to date and accurate and has not since then been materially altered and that such searches did not fail to disclose any material information that had been delivered for registration at the time of our search but did not appear on-line or on the file in London (as applicable) at the time of our search, and that the information relating to the Company disclosed by our on-line searches and by telephone included all material information and disclosed all petitions for an administration order or winding up, if any, in respect of the Company that have been presented in England and Wales;

(j)

that the meetings of the Board of Directors of the Company and the Corporate Administration & Transactions Committee of the Company, at which the resolutions authorising the relevant Companies to enter into the Transaction Documents were passed, were duly convened and held, and such resolutions are a true record of the proceedings at such meetings and are in full force and effect and have not been amended, revoked or superseded;

(k)

that there are no provisions of the laws of any jurisdiction outside England and Wales that would have any implication for the opinions we express and that, insofar as the laws of any jurisdiction outside England and Wales may be relevant to this opinion letter, such laws have been and will be complied with;

(l)

that any limit on borrowings to which the Company is subject has not been exceeded, and that the entry into or the performance of the Transaction Documents will not cause any such limit on borrowings to be exceeded;

(m)

that any party to the Transaction Documents that is subject to the supervision of any regulatory authority in the United Kingdom has complied and will comply with the requirements of such regulatory authority in connection with the offering and sale of the Debt Securities;

(n)

that the terms and conditions applicable to the relevant Debt Securities will not be inconsistent with the terms and conditions of the relevant Indenture and will not be inconsistent with the Final Prospectus;

A-2-4

(r)

that all consents, approvals, notices, filings and registrations that are necessary under any applicable laws or regulations (other than laws or regulations of the United Kingdom) in order to permit the execution, delivery or performance of the Transaction Documents have been or will be duly made or obtained;

(s)

that the 2004 Company Memorandum and Articles were in full force and effect and had not been amended, revoked or superseded as at the date of execution of the Indenture on March 4, 2008;

(t)

that the binding effect of the Transaction Documents on the parties thereto is not affected by duress, undue influence or mistake, and no document has been entered into by any of the parties thereto in connection with any unlawful activity;

(u)

that each director of the Company has disclosed any interest which he may have in the transactions contemplated by each of the Transaction Documents in accordance with the provisions of the Companies Xxx 0000 and the Companies Xxx 0000 and the articles of association of the Company, and that none of the relevant directors of the Company have any interest in such transactions except to the extent permitted by the articles of association of the Company;

(v)

that the execution and delivery of each of the Transaction Documents by the Company, and the exercise of the Company’s rights and performance of the Company’s obligations thereunder will materially benefit the Company and that the directors of such Company acted in good faith and in the interests of such party in approving each of the Transaction Documents and the transactions contemplated thereby; and

(w)

that the directors of the Company acted in good faith and in the interest of the Company in approving the Transaction Documents and the transactions contemplated thereby.

Based on the foregoing, and subject to the further qualifications and limitations set forth below, it is our opinion that:

1. the Company has been duly incorporated as a public limited company under the laws of England and Wales. A search of the records of the Registrar of Companies as made public through the xxx.xxxxxxxxxxxxxx.xxx.xx website on [ ], 20[ ] and an oral enquiry made to the Central Registry of Winding up Petitions at the Companies Court at approximately [ ] AM GMT on [ ], 20[ ] revealed no petition, order or resolution for the winding up of the Company and no petition for, and no notice of appointment of, a receiver or administrator, provided that:

(a)

the searches with Companies House referred to above are not conclusively capable of revealing whether or not (i) a winding up order has been made in respect of a company or a resolution passed for the winding up of a company, or (ii) an administration order has been made in respect of a company, or (iii) a receiver, administrative receiver, administrator or liquidator has been appointed in respect of a company, since notice of these matters might not be filed with Companies House immediately and, when filed, might not be made available through the website or entered on the files of Companies

A-2-5

House relating to insolvency details with respect to the relevant company immediately. In addition, such searches are not capable of revealing, prior to the making of the relevant order, whether or not a winding up petition or a petition for an administration order has been presented; and

(b)

the enquiry at the Central Registry of Winding up Petitions at the Companies Court referred to above relates only to a compulsory winding up and is not capable of revealing conclusively whether or not a winding up petition in respect of a compulsory winding up has been presented since details of the petition may not have been entered on the records of the Central Registry of Winding up Petitions immediately or, in the case of a petition presented to a County Court, may not have been notified to the Central Registry and entered on such records at all, and the response to an enquiry only relates to the period of six months prior to the date when the enquiry was made. We have not made enquiries of any County Court as to whether a petition for the appointment of an administrator has been presented to, or an administration order has been made by, any County Court against the Company.

2. The Company possesses the corporate power and authority to enter into and perform its obligations under each of the Transaction Documents to which it is a party.

3. The Company has duly authorised, executed and delivered each of the Transaction Documents to which it is a party.

4. No consent, approval, authorisation, order, licence, registration and qualification or filing of or with any court or governmental agency or body in the United Kingdom is required for the issue and initial sale of the Debt Securities in the manner contemplated in the Prospectus and the Transaction Documents or the execution or delivery of the Transaction Documents.

5. Neither the execution nor the delivery of the Indenture by the Company nor the performance will conflict with or violate or result in a breach of or constitute a default under any term or provision of its Memorandum or Articles of Association.

6. Under English law and practice as currently applied, the choice of the law of the State of New York to govern each of the Underwriting Agreement and the Indenture and the construction and interpretation thereof as between the parties thereto is a valid choice of law under English law provided it was freely made. Such choice of law will be recognised and upheld by the English courts and in any action to enforce each of the Underwriting Agreement or Indenture brought before the English courts having jurisdiction in the matter, the English courts will apply the law of the State of New York in relation thereto. The English courts have the discretion not to apply the law of the State of New York if and so far as its application would lead to results contrary to fundamental principles of public policy. In addition, the English courts are entitled to apply the laws of England and Wales whose application is mandatory and which cannot be derogated from by contract.

A-2-6

7. A final, conclusive and non-appealable judgment for a definite sum of a U.S. Federal or state court sitting in New York City against the Company arising out of the Transaction Documents would be recognised and enforced, without re-examination or re-litigation of the matters adjudicated upon by the English courts, provided that:

(a)

the judgment was not obtained by fraud;

(b)

the enforcement of the judgment would not be contrary to English public policy or violate the Human Rights Xxx 0000;

(c)

the judgment was not obtained in proceedings contrary to natural justice;

(d)

the judgment is not inconsistent with an English judgment in respect of the same point at issue;

(e)

the judgment is not for multiple damages (as defined by the Protection of Trading Interests Act 1980);

(f)

enforcement proceedings are instituted within six years after the date of the judgment;

(g)

the judgment is not of a public, penal or revenue nature;

(h)

the judgment was not obtained in proceedings that were brought in breach of section 32 of the Civil Jurisdiction and Judgments Xxx 0000; and

(i)

the U.S. Federal or state court sitting in New York City had jurisdiction over such Company according to English conflict of laws rules.

8. The statements set forth in the Final Prospectus Supplement under the heading “Tax Considerations—U.K. Taxation”, insofar as such statements purport to summarise certain tax laws of the United Kingdom and certain administrative practice of HM Revenue and Customs, fairly summarise such laws and practice subject to the limitations, assumptions and reservations stated therein and under the general heading “Tax Considerations.”

9. Section 21 of FSMA contains a prohibition on the communication in the course of business by any person other than an authorised person under FSMA of an invitation or inducement to engage in investment activity, subject to certain exceptions. Contravention of this prohibition in connection with the offering or sale of any Debt Securities could involve, inter alia, certain agreements relating to the offering or sale of such Debt Securities being unenforceable. Communications by the Company will not be subject to such prohibition if the requirements of Articles 12, 19 and/or 49 of the Financial Services and Markets Xxx 0000 (Financial Promotion) Order 2005 (the “Order”) or any other relevant Article (or, where permitted, combination of relevant Articles) of the Order are complied with. We express no opinion on the compliance or otherwise by any of the Underwriters with the Financial Promotion Rules made under section 145 of FSMA.

A-2-7

The foregoing does not mean that obligations assumed by the relevant party under the relevant document will necessarily be enforced in all circumstances in accordance with their terms. In particular, but without limitation:

(a)

The opinions set forth above are subject to all limitations resulting from the laws of bankruptcy, administration, liquidation, insolvency, fraudulent transfer, reorganisation, moratorium, suretyship or any similar laws of general application affecting creditors’ rights.

(b)

Enforcement may be limited by general principles of equity. For example, equitable remedies may not be available where damages are considered to be an adequate remedy.

(c)

Where any obligations of any person are to be performed or observed in jurisdictions outside England and Wales, or by a person subject to the laws of a jurisdiction outside England and Wales, such obligations may not be enforceable under English law to the extent that the performance or observance thereof would be illegal or contrary to public policy under the laws of any such jurisdiction.

(d)

The effectiveness of provisions in the Transaction Documents relating to the choice of law to govern non-contractual obligations will be subject, where applicable, to Council Regulation (EC) n°864/2007 on the law applicable to non-contractual obligations (the “Rome II Regulation”). The Rome II Regulation provides that, in certain circumstances, the choice of English law to govern non-contractual obligations may not prejudice or restrict the application of other laws where such laws are mandatory or cannot be derogated from by contract.

(e)

Except in those cases where jurisdiction is determined in accordance with Council Regulation (EC) n°44/2001 on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters, the provisions of the Brussels Convention on jurisdiction in civil and commercial matters of 1968, or the provisions of the Lugano Convention on jurisdiction and the enforcement of judgments in civil and commercial matters of 1988, an English court has power to stay an action where it is shown that it can, without injustice to the plaintiff, be tried in a more convenient forum. However, such power may not be exercisable in all circumstances. For example, an English court may not be able to stay proceedings where the defendant is domiciled in England and the alternative jurisdiction is outside the European Union.

(f)

Any provision providing that any calculation, certification, determination, notification, minute or opinion will be conclusive and binding will not be effective if such calculation, certification, determination, notification, minute or opinion is fraudulent or made on an unreasonable or arbitrary basis or in the event of manifest error despite any provision to the contrary and it will not necessarily prevent judicial enquiry into the merits of any claim by any party thereto.

A-2-8

(g)

Where any person is vested with a discretion, or may determine any matter in its opinion, English law may require that such discretion is exercised reasonably or that such opinion is based on reasonable grounds.

(h)

Any provision for the payment of liquidated damages, compensation, additional interest or similar amounts might be held to be unenforceable on the ground that it is a penalty.

(i)

Any undertaking or indemnity may be void insofar as it relates to stamp duty payable in the United Kingdom.

(j)

An English court may refuse to give effect to any provision of an agreement that amounts to an indemnity in respect of the costs of enforcement or of unsuccessful litigation brought before an English court or where the court has itself made an order for costs.

(k)

Where an English court finds that a term of a contract is open to more than one interpretation (in this regard we refer you to Rainy Sky SA and others v Kookmin Bank [2011] UKSC 50), the court may apply the interpretation that it finds to be most consistent with business common sense and reject any other.

(l)

Any question as to whether or not any provision of any agreement or instrument that is illegal, invalid, not binding, unenforceable or void may be severed from the other provisions thereof in order to save those other provisions would be determined by an English court in its discretion.

(m)

There is some possibility that an English court would hold that a judgment on a particular agreement or instrument, whether given in an English court or elsewhere, would supersede such agreement or instrument to all intents and purposes, so that any obligation thereunder that by its terms would survive such judgment might not be held to do so.

(n)

Enforcement of rights may be or become limited by prescription or by the lapse of time or may be or become subject to defences of set-off or counterclaim.

(o)

The effectiveness of terms exculpating a party from a liability or duty otherwise owed or limiting such liability or duty is limited by law.

(p)

An English court is able, where the amount of a claim is denominated in a currency other than sterling, to give judgment in that other currency, as a matter of current procedural practice and at its own discretion.

(q)

There is some possibility that an English court having jurisdiction in relation to insolvency law would apply the provisions of Section 426 of the Insolvency Xxx 0000 (Co-operation between courts exercising jurisdiction in relation to insolvency) in assisting the courts having the corresponding jurisdiction in any other part of the United Kingdom or any relevant country or territory (as such terms are defined in that section) (in this regard we refer you to Xxxxxx v. Hannover

A-2-9

Ruckversicherungs-Aktiengesellschaft [1997] 1 BCLC 497) and, as a result, may, rather than apply insolvency law as it would otherwise apply in England, apply the insolvency law that is applicable in such other part of the United Kingdom or relevant country or territory in relation to comparable matters.

(r)

An English court may refuse to give effect to a claim pursuant to an indemnity or contribution provision in a Transaction Document insofar as the subject matter of such claim relates to penalties imposed under Section 91 (breach of Part 6 rules) or Section 123 (market abuse) of FSMA or any relevant provision of FSMA imposing penalties or of the rules made under it.

(s)

Certain terms and concepts, although often found in commercial documents, have yet to be clearly defined by the English courts. To the extent that the Transaction Documents contain any such terms or concepts, their meaning will be a matter of construction for an English court.

(t)

Any provision of an agreement which purports to grant an irrevocable power of attorney or other authorization or irrevocably appoint a person as agent may nevertheless not be treated by an English court as irrevocable.

(u)

A court may not, for lack of certainty, enforce a provision which purports to require parties to reach a further agreement in the future.

We express no opinion as to any agreement, instrument or other document that may arise or be entered into, or as to any liability to tax or obligation to report to any tax authority that may arise or be incurred (other than as set forth in numbered paragraph 8 above), as a result of or in connection with the Transaction Documents, including, without limitation, the creation, issue or offer of the Debt Securities or any other transaction. We have not been responsible for the investigation or verification of statements of fact (including statements as to foreign law) or the reasonableness of any statements of opinion contained in the Registration Statement, the Pricing Prospectus, the Final Term Sheet or the Final Prospectus relating to the issue of the Debt Securities, or the entry into the Underwriting Agreement or the Indenture, nor have we been responsible for ensuring that the Registration Statement, the Pricing Prospectus, the Final Term Sheet and the Final Prospectus and the documents incorporated by reference therein contain all material facts.

The opinions set out above are limited to the laws of England and Wales in force as at the date of this opinion letter, as currently applied by the courts in England and Wales (and, in the case of the opinion in numbered paragraph 8 above, to U.K. tax law as currently applied by those courts and to the published practices of HM Revenue & Customs applicable at the date of this opinion letter) and are given on the basis that this opinion letter will be governed by and construed in accordance with English law.

We are furnishing this opinion letter to you, as Representatives of the several Underwriters, solely for the benefit of the Underwriters in their capacity as such in connection with the offering of the Debt Securities. This opinion letter is not to be relied on by or furnished to any other person or used, circulated, quoted or otherwise referred to for any other purpose.

A-2-10

Notwithstanding the foregoing, you may furnish a copy of this opinion letter (with notice to us, which shall be given before furnishing such copy, when practicable) (i) if required by any applicable law or regulation; (ii) to any regulatory authority having jurisdiction over you if required by such authority; or (iii) in connection with any actual or threatened claim against you relating to the offer and sale of the Debt Securities if required to assist you in establishing defences under applicable securities laws, it being understood and agreed that we assume no duty or liability whatsoever to any person furnished this opinion letter in accordance with this sentence and that any such person is not entitled to rely on this opinion letter in any manner as a result or otherwise.

The opinions expressed herein are rendered on and as of the date hereof, and we assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinions expressed herein.


Very truly yours,

EXHIBIT B

[Form of Letter of Counsel to the Company]

[ ], 20[ ]

[ ]

as Representatives of the several Underwriters

c/o [ ]

Ladies and Gentlemen:

We have acted as special United States counsel to GlaxoSmithKline plc, a public limited company incorporated in England and Wales (the “Company”), in connection with the offering from time to time, together or separately and in one or more series, pursuant to a registration statement on Form F-3 (No. 333-[ ]) of debt securities of the Company (the “Debt Securities”). Such registration statement, as amended as of its most recent effective date ([ ], 20[ ]), insofar as it relates to the Debt Securities (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)), but excluding the documents incorporated by reference therein and Exhibit 25, is herein called the “Registration Statement;” the related prospectus dated [ ], 20[ ], included in the Registration Statement filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Base Prospectus;” the preliminary prospectus supplement dated [ ], 20[ ], as filed with the Commission pursuant to Rule 424(b) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Preliminary Prospectus Supplement;” and the related prospectus supplement dated [ ], 20[ ], as filed with the Commission pursuant to Rule 424(b) under the Securities Act, but excluding the documents incorporated by reference therein, is herein called the “Final Prospectus Supplement.” The Base Prospectus and the Preliminary Prospectus Supplement together are herein called the “Pricing Prospectus,” and the Base Prospectus and the Final Prospectus Supplement together are herein called the “Final Prospectus.” This letter is furnished to you pursuant to Section 6(c) of the underwriting agreement dated [ ], 20[ ] (the “Underwriting Agreement”) between the Company and the several underwriters named in Schedule II thereto (the “Underwriters”).

Because the primary purpose of our professional engagement was not to establish or confirm factual matters or financial, accounting or statistical information, and because many determinations involved in the preparation of the Registration Statement, the Pricing Prospectus, the Final Prospectus, the documents incorporated by reference in each of them and the documents listed in Schedule I hereto are of a wholly or partially non-legal character or relate to legal matters outside the scope of our opinion letter to you of even date herewith, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Pricing Prospectus, the Final Prospectus, the documents incorporated by reference in each of them or the documents listed in Schedule I hereto (except to the extent expressly set forth in numbered

B-1

paragraph 5 of our opinion letter to you of even date herewith) and we make no representation that we have independently verified the accuracy, completeness or fairness of such statements (except as aforesaid). We also are not passing upon and do not assume any responsibility for ascertaining whether or when any of the Pricing Prospectus, the Final Prospectus, the documents incorporated by reference in each of them or the documents listed in Schedule I hereto was conveyed to any person for purposes of Rule 159 under the Securities Act.

However, in the course of our acting as special United States counsel to the Company in connection with its preparation of the Registration Statement, the Pricing Prospectus, the Final Prospectus and the documents listed in Schedule I hereto, we participated in conferences and telephone conversations with representatives of the Company, representatives of the independent public accountants for the Company, your representatives and representatives of your counsel, during which conferences and conversations the contents of the Registration Statement, the Pricing Prospectus, the Final Prospectus, portions of certain of the documents incorporated by reference in each of them and the documents listed in Schedule I hereto and related matters were discussed, and we reviewed certain corporate records and documents furnished to us by the Company.

Based on our participation in such conferences and conversations and our review of such records and documents as described above, our understanding of the U.S. federal securities laws and the experience we have gained in our practice thereunder, we advise you that:

(a) The Registration Statement (except the financial statements and schedules and other financial and statistical data included therein, as to which we express no view), at the time it became effective, and the Final Prospectus (except as aforesaid), as of the date thereof, appeared on their face to be appropriately responsive in all material respects to the requirements of the Debt Securities Act and the Trust Indenture Act of 1939, as amended, and the rules and regulations thereunder.

(b) The documents incorporated by reference in the Registration Statement and the Final Prospectus (except the financial statements and schedules and other financial and statistical data and management’s report on the effectiveness of internal control over financial reporting included therein, as to which we express no view), as of the respective dates of their filing with the Commission, appeared on their face to be appropriately responsive in all material respects to the requirements of the Debt Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder.

(c) No information has come to our attention that causes us to believe that the Registration Statement, including the documents incorporated by reference therein (except the financial statements and schedules and other financial and statistical data and management’s report on the effectiveness of internal control over financial reporting included therein, as to which we express no view), at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

B-2

(d) No information has come to our attention that causes us to believe that the Pricing Prospectus, including the documents incorporated by reference therein considered together with the documents listed in Schedule I hereto (except in each case the financial statements and schedules and other financial and statistical data and management’s report on the effectiveness of internal control over financial reporting included in the Pricing Prospectus, as to which we express no view), at the time of execution of the Underwriting Agreement, contained an untrue statement of a material fact or omitted 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.

(e) No information has come to our attention that causes us to believe that the Final Prospectus, including the documents incorporated by reference therein (except the financial statements and schedules and other financial and statistical data and management’s report on the effectiveness of internal control over financial reporting included therein, as to which we express no view), as of the date thereof or hereof, contained or contains an untrue statement of a material fact or omitted or omits 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.

We confirm to you that (a) based solely upon email confirmation of receipt of the filing and Rule 462(e) under the Securities Act, the Registration Statement is effective under the Securities Act, and (b) based solely upon a telephonic confirmation from a representative of the Commission, no stop order with respect thereto has been issued by the Commission, and, to the best of our knowledge, no proceeding for that purpose has been instituted or threatened, by the Commission.

We are furnishing this letter to you, as Representatives of the Underwriters, solely for the benefit of the Underwriters in their capacity as such in connection with the offering of the Debt Securities. This letter is not to be relied on by or furnished to any other person or used, circulated, quoted or otherwise referred to for any other purpose. We assume no obligation to advise you, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the views expressed herein.
