Notice to Prospective Investors in the European Economic Area
Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Directive (as defined below).
This prospectus supplement, the accompanying prospectus and any related free-writing prospectus have been prepared on the basis that any offer of Notes
in any Member State of the European Economic Area (the "EEA") which has implemented the Prospectus Directive (each, a "Relevant Member State")
will only be made to a legal entity which is a qualified investor under the Prospectus Directive ("Qualified Investors"). Accordingly any person making or
intending to make an offer in that Relevant Member State of Notes which are the subject of the offering contemplated in this prospectus supplement, the
accompanying prospectus and any related free-writing prospectus may only do so with respect to Qualified Investors. Neither we nor the underwriters have
authorised, nor do they authorise, the making of any offer of Notes other than to Qualified Investors. The expression "Prospectus Directive" means
Directive 2003/71/EC (as amended, including by Directive 2010/73/EU), and includes any relevant implementing measure in the Relevant Member State.

S-1
Table of Contents
PRIIPs Regulation / Prospectus Directive / Prohibition of sales to EEA retail investors--The Notes are not intended to be offered, sold or
otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a retail
investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended ("MiFID
II"); or (ii) a customer within the meaning of Directive 2002/92/EC, as amended (the "Insurance Mediation Directive"), where that customer would not
qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Directive.
Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the "PRIIPs Regulation") for offering or selling the
Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making
them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.
Notice to Prospective Investors in the United Kingdom
The communication of this prospectus supplement, the accompanying prospectus and any other document or materials relating to the issue of the
Notes offered hereby is not being made, and such documents and/or materials have not been approved, by an authorized person for the purposes of section
21 of the United Kingdom's Financial Services and Markets Act 2000, as amended (the "FSMA"). Accordingly, such documents and/or materials are not
being distributed to, and must not be passed on to, the general public in the United Kingdom. The communication of such documents and/or materials as a
financial promotion is only being made to those persons in the United Kingdom who have professional experience in matters relating to investments and
who fall within the definition of investment professionals (as defined in Article 19(5) of the Financial Services and Markets Act 2000 (Financial
Promotion) Order 2005, as amended (the "Financial Promotion Order")), or who fall within Article 49(2)(a) to (d) of the Financial Promotion Order, or
who are any other persons to whom it may otherwise lawfully be made under the Financial Promotion Order (all such persons together being referred to as
"relevant persons"). In the United Kingdom, the Notes offered hereby are only available to, and any investment or investment activity to which this
prospectus supplement, the accompanying prospectus or any related free-writing prospectus relates will be engaged in only with, relevant persons. Any
person in the United Kingdom that is not a relevant person should not act or rely on this prospectus supplement, the accompanying prospectus and any
related free-writing prospectus or any of their contents.
MiFID II product governance
MiFID II product governance / Professional investors and ECPs only target market--In the EEA and solely for the purposes of the product
approval process conducted by any underwriter who is a manufacturer with respect to the Notes for the purposes of the MiFID II product governance rule
under EU Delegated Directive 2017/593 (each, a "manufacturer"), the manufacturers' target market assessment in respect of the Notes has led to the
conclusion that: (i) the target market for the Notes is eligible counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels
for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending
the Notes (a "distributor") should take into consideration the manufacturers' target market assessment; however, a distributor subject to MiFID II is
responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturers' target market
assessment) and determining appropriate distribution channels.
We are responsible for the information contained and incorporated by reference in this prospectus supplement and the accompanying prospectus and
in any related free-writing prospectus we prepare or authorize. We have not authorized anyone to give you any other information, and we take no

and interest thereon will continue to accrue to but excluding such succeeding business day,
except that if that business day falls in the next succeeding calendar month, the Floating Rate
Interest Payment Date will be the immediately preceding business day and interest shall
accrue to but excluding such preceding business day. If the maturity date or a redemption
date for the Floating Rate Notes would fall on a day that is not a business day, the required
payment will be made on the next succeeding business day, but no additional interest shall
accrue and be paid unless we fail to make payment on such next succeeding business day.

Calculation of U.S. dollar LIBOR
LIBOR will be determined by the calculation agent in accordance with the following
provisions:

·
With respect to any Interest Determination Date, LIBOR will be the rate
(expressed as a percentage per year) for deposits in U.S. dollars having a maturity
of three months commencing on May 15, 2018 or the related Interest Reset Date, as

applicable, that appears on Reuters Page LIBOR01 (as defined below) as of 11:00
a.m., London time, on that Interest Determination Date. If no such rate appears,
then LIBOR, in respect of that Interest Determination Date, will be determined in
accordance with the provisions described in the following paragraph.

·
With respect to an Interest Determination Date on which no rate appears on
Reuters Page LIBOR01, the calculation agent will request the principal London
offices of each of four major reference banks in the London interbank market

representative for a single transaction in U.S. dollars in that market at that time. If
at least two quotations are provided, then LIBOR on that Interest Determination
Date will be the arithmetic mean of those quotations. If fewer than two quotations
are provided, then LIBOR on the Interest Determination Date will be the arithmetic
mean of the rates

quoted at approximately 11:00 a.m., in the City of New York, on the Interest
Determination Date by three major banks in the City of New York (which may
include affiliates of the underwriters), as selected and identified by us (together with
the London Reference Banks, the "Reference Banks"), for loans in U.S. dollars to
leading European banks, for a period of three months, commencing on May 15,

2018 or the related Interest Reset Date, as applicable, and in a principal amount that
is representative for a single transaction in U.S. dollars in that market at that time.
If at least two such rates are so provided, LIBOR on the Interest Determination Date
will be the arithmetic mean of such rates. If fewer than two such rates are so
provided, LIBOR on the Interest Determination Date will be LIBOR in effect with
respect to the immediately preceding Interest Determination Date.

prior to maturity other than in the event of certain changes in U.K. or U.S. withholding taxes
applicable to payments of interest as described under "Description of Debt Securities--
Optional Redemption for Tax Reasons" in the accompanying prospectus.

Terms applicable to all the Notes

Payment of additional amounts
Subject to certain exceptions, if we are required to withhold or deduct any amount for or on
account of any U.K. or U.S. withholding tax from any payment made on the Notes, we will
pay additional amounts on those payments so that the amount received by noteholders will
equal the amount that would have been received if no such taxes had been applicable. See
"Description of the Notes--Covenants--Payment of Additional Amounts. "

Tax redemption
In the event of changes in U.K. or U.S. withholding taxes applicable to payments of interest,
we may redeem the Notes of a series in whole (but not in part) at any time prior to maturity,
at a price equal to 100% of their principal amount plus accrued interest to the redemption
date. See "Description of Debt Securities--Optional Redemption for Tax Reasons " in the
accompanying prospectus.

No repayment
The Notes will not be subject to repayment at the option of the holder prior to maturity.

Ranking
The Notes and the guarantee will rank equally in right of payment with all other senior,
unsecured debt obligations of the respective issuer and GlaxoSmithKline plc, respectively.

Sinking fund
None.

Book-entry issuance, settlement and clearance
We will issue the Notes of each series as global notes in book-entry form registered in the
name of DTC or its nominee. The sale of the Notes will settle in immediately available funds
through DTC. Investors may hold interests in a global note through organizations that
participate, directly or indirectly, in the DTC system. Those organizations will include
Clearstream and Euroclear in Europe.

Governing law
The Notes and the guarantee will be governed by the laws of the State of New York.

Further issuances
We may from time to time, without the consent of the holders of a series of Notes, create and
issue further debt securities of the same series having the same terms and conditions in all
respects as the Notes of that series being offered hereby, except for the issue date, the issue
price and the first payment of interest thereon. Any such additional debt securities shall be
issued under a separate CUSIP or ISIN number unless the additional debt securities are
issued pursuant to a "qualified reopening" of the original series, are otherwise treated as part
of the same "issue" of debt instruments as the original series or are issued with no more than
a de minimis amount of original discount, in each case for U.S. federal income tax purposes.

Listing
We intend to list the Notes of each series on the New York Stock Exchange or another
recognized stock exchange.

Use of proceeds
We intend to use the net proceeds from the sale of the Notes for our general corporate
purposes, which may include funding to acquire full ownership of the Consumer Healthcare
business from Novartis as discussed in the 2018 Circular.

RISK FACTORS
Our 2017 Form 20-F, which is incorporated by reference in this prospectus supplement, includes risk factors relating to our business. You should
carefully consider those risks and the risks relating to the Notes described below, as well as the other information included or incorporated by reference
into this prospectus supplement and the accompanying prospectus, before making a decision to invest in the Notes.
Risks Relating to the Notes
https://www.sec.gov/Archives/edgar/data/1131399/000119312518162878/d542333d424b2.htm[5/15/2018 9:38:42 AM]

424B2
The Notes lack developed public markets.
There can be no assurance regarding the future development of a market for the Notes or the ability of holders of the Notes to sell their Notes or the
price at which such holders may be able to sell their Notes. If such a market were to develop, it could develop for only one series of Notes and not others
and such Notes could trade at prices that may be higher or lower than the initial offering price depending on many factors, including, among other things,
prevailing interest rates, our operating results and the market for similar securities. Underwriters, broker-dealers and agents that participate in the
distribution of the Notes may make a market in the Notes as permitted by applicable laws and regulations but will have no obligation to do so, and any such
market-making activities with respect to any, some or all of the Notes may be discontinued at any time without notice. Therefore, there can be no
assurance as to the liquidity of any trading market for the Notes of any series or that an active public market for the Notes of any series will develop or be
maintained. See "Underwriting." We intend to apply for listing of the Notes of each series on the New York Stock Exchange or another recognized stock
exchange; however, there can be no assurance that the Notes of each series will be so listed by the time the Notes are delivered to purchasers or at all.
We may redeem the Fixed Rate Notes at any time prior to maturity and the Notes of any series for certain tax reasons.
The respective issuer may redeem the Fixed Rate Notes of one or more series in whole (but not in part) prior to maturity as more particularly
described under "Description of the Notes--Optional Make-Whole Redemption." Moreover, we may redeem the Notes of any series at any time prior to
maturity in whole (but not in part) upon the occurrence of certain tax events, as more particularly described under "Description of Debt
Securities--Optional Redemption for Tax Reasons" in the accompanying prospectus. Certain of such tax events may occur at any time after the issue date
and it is therefore possible that the respective issuer would be able to redeem the Notes of one or more series at any time after the issue date. If we redeem
the Notes in any of the circumstances mentioned above, you may not be able to reinvest the redemption proceeds in comparable securities with the same or
higher yield.
None of GSK Capital Inc., GSK Capital plc or GlaxoSmithKline plc is prohibited from issuing further debt.
There is no restriction on the amount of debt GSK Capital Inc. or GSK Capital plc may issue that ranks equally with the applicable series of Notes or
on the amount of debt or guarantees GlaxoSmithKline plc may issue that ranks equally with the guarantee on the Notes. The issuance of any such debt or
guarantees may reduce the amount recoverable by you in the event of a liquidation or bankruptcy.
In particular, we may from time to time, without the consent of the holders of a series of Notes, create and issue one or more additional series of debt
securities through the accompanying prospectus or create and issue further debt securities of the same series having the same terms and conditions in all
respects as the applicable Notes being offered hereby, except for the issue date, the issue price and the first payment of interest thereon. See "Description of
the Notes--Further Issuances."
As GlaxoSmithKline plc is a holding company, its obligations as guarantor are structurally subordinated to liabilities of its subsidiaries.
GlaxoSmithKline plc is organized as a holding company, and substantially all of its operations are carried out through subsidiaries. GlaxoSmithKline
plc's ability to meet its financial obligations is thus dependent upon

S-11
Table of Contents
the availability of cash flows from its domestic and foreign subsidiaries and affiliated companies through dividends, intercompany advances and other
payments. The Notes are obligations of GSK Capital Inc. and GSK Capital plc, as applicable, and are guaranteed exclusively by GlaxoSmithKline plc. The
subsidiaries of GlaxoSmithKline plc are separate and distinct legal entities, and, other than GSK Capital Inc. and GSK Capital plc, have no obligation to
pay any amounts due on the guarantee on the Notes or to provide GSK Capital Inc., GSK Capital plc and GlaxoSmithKline plc with funds for the payment
obligations under the Notes.
Moreover, claims of the creditors and preferred equity holders of GlaxoSmithKline plc's subsidiaries have priority as to the assets of such
subsidiaries over the claims of GlaxoSmithKline plc as a common equity holder of such subsidiaries. Consequently, in the event of the liquidation or
reorganization of any of GlaxoSmithKline plc's subsidiaries, the claims of holders of the Notes to participate in those assets through the guarantee on the
Notes would be structurally subordinated to the prior claims of the creditors and preferred equity holders of subsidiaries of GlaxoSmithKline plc.
Our credit rating may not reflect the potential impact of all risks related to structure and other factors on any trading market for, or market value
of, the Notes. A credit rating is not a recommendation to buy, sell or hold securities and may be revised or withdrawn by the rating agency at any
time in its sole discretion.
Any rating assigned to us may be withdrawn entirely by a credit rating agency, may be suspended or may be lowered, if, in that credit rating
agency's judgment, circumstances relating to the basis of the rating so warrant. Ratings may be impacted by a number of factors that can change over time,
including the credit rating agency's assessment of: our strategy and management's capability; our financial condition and liquidity; competitive, economic,
legal and regulatory conditions in our key markets, including those markets where we have large exposures or on which our operating results, including
revenues, are substantially dependent; the level of political support for the industries in which we operate; and legal and regulatory frameworks affecting
our legal structure, business activities and the rights of our creditors. Moreover, the rating agencies that currently, or may in the future, publish a rating for
us may change the methodologies that they use for analyzing securities with features similar to the Notes.
