By Shire Plc, PRNE
Thursday, October 28, 2010

DUBLIN, October 29, 2010 - Shire plc (LSE: SHP, NASDAQ: SHPGY) the global specialty
biopharmaceutical company, announces results for the three months to
September 30, 2010.

    Financial Highlights                                 Q3 2010(2)

    Product sales(1)                                 $794 million    +32%
    Total revenues                                   $874 million    +31%
    Non GAAP operating income                        $298 million   +123%
    US GAAP operating income                         $156 million    +70%
    Non GAAP diluted earnings per ADS                $1.16          +138%
    US GAAP diluted earnings per ADS                 $0.52           +59%

(1) Product sales excluding ADDERALL XR ("Core Product Sales") were up
31% to $694 million. Core Product Sales at constant exchange rates ("CER"),
computed by restating 2010 results using average 2009 foreign exchange rates,
were up 34%.

(2) Percentages compare to equivalent 2009 period.

Angus Russell, Chief Executive Officer, commented:

"We delivered another outstanding set of results this quarter with strong
revenue growth and operating leverage driving increases in Non GAAP earnings.
This continued excellent performance demonstrates the overall strength of
Shire's business and the sustained execution of our strategy.

In ADHD, VYVANSE sales are up 17% and the number of new physicians
prescribing INTUNIV continues to increase.

Sales of REPLAGAL have increased by 91% as we respond to the great need
of our Fabry patients; we estimate that our global market share now exceeds
60%. Only seven months into the initial launch of our treatment for Gaucher
patients, around 1,000 patients are now on VPRIV, representing a 16% global
market share.

We've made progress in several significant programs in our research and
development pipeline, including investigative uses of VYVANSE for adjunctive
therapy in patients with Major Depressive Disorder ("MDD"). We've also
recently completed our acquisition of Movetis NV, bringing the approved
product RESOLOR to our gastro-intestinal ("GI") portfolio, and announced the
in-licence from Acceleron of a Phase 2 orphan drug for Duchenne Muscular
Dystrophy.

Alongside delivery of these outstanding quarterly results, we're building
our business for the future. We're investing to enhance the value of our
product pipeline, building our international structure to maximise the global
reach of our products and using our strong cash generation to complete value
enhancing acquisitions and in-licenses.

We now expect to see Non GAAP earnings of up to $4.20 per ADS for the
full year. This includes the financial effect of the Movetis acquisition and
the DAYTRANA disposal. Looking ahead, we re-iterate our aspirational target
of mid-teens sales growth on average between 2009 and 2015."

The Non GAAP financial measures included within this release are
explained on page 26, and are reconciled to the most directly comparable
financial measures prepared in accordance with US GAAP on pages 21 - 24.

    - Product sales were up 32% to $794 million (2009: $603 million) due to
      growth from both Core Products Sales (up 31% to $694 million) and
      ADDERALL XR(R), (up 41% to $100 million). On a CER basis, which is a
      Non GAAP measure, Core Product Sales were up 34%.

    - Core Products Sales growth was driven by both existing and new
      products, particularly REPLAGAL(R) (up 91% to $92 million; CER: up
      103%), VYVANSE(R) (up 17% to $151 million) and recently launched
      VPRIV(R) ($50 million) and INTUNIV(R) ($37 million).

    - Total revenues were up 31% (CER: up 34%) to $874 million (2009: $667
      million), as a result of higher product sales and higher royalty income
      on authorized generic sales of ADDERALL XR compared to Q3 2009.

    - Non GAAP operating income increased by $164 million, or 123%, to $298
      million (2009: $134 million) as the increased investments we are making
      in our research and development ("R&D") programs and selling, general
      and administrative ("SG&A") activities to support recent growth were
      more than offset by higher revenues compared to 2009. On a US GAAP
      basis, operating income increased by $64 million, or 70%, to $156
      million (2009: $92 million). US GAAP operating income in Q3 2010 also
      included an up-front payment of $45 million made to Acceleron Pharma
      Inc. ("Acceleron") in relation to the collaboration for activin
      receptor type IIB ("ActRIIB") molecules and impairment charges of $43
      million following the decision to divest DAYTRANA(R) to Noven
      Pharmaceuticals Inc. ("Noven").

    - Cash generation, which is a Non GAAP measure, increased by $51 million
      to $271 million (2009: $220 million). Higher cash receipts from product
      sales and royalties were partially offset by higher cash payments on
      the increased investment in R&D and SG&A, and the timing of sales
      deduction payments in 2010.

    - Net debt at September 30, 2010 was $309 million (December 31, 2009:
      $615 million), a reduction of $306 million in the year to date. Strong
      cash generation of $959 million in the nine months to September 30,
      2010 has reduced net debt as well as funded the acquisition of and
      construction at Lexington Technology Park, cash tax payments and the
      upfront payment made to Acceleron. Excluding restricted cash of $584
      million held to pay for the acquisition of Movetis NV ("Movetis") in
      the fourth quarter, net debt at September 30, 2010 was $893 million.

2010 OUTLOOK

Following a stronger than expected third quarter, we have increased our
expectations for the full year 2010. We now expect to see Non GAAP earnings
per ADS of up to $4.20. This increase includes the financial effect of the
Movetis acquisition and the disposal of DAYTRANA on October 1, 2010; it also
includes the cumulative impact of US Healthcare Reform, mandated European
price cuts and adverse foreign exchange rates.

The strong growth of our core portfolio will continue to drive total
revenue growth; however, the rate of growth will reduce in the fourth quarter
as we will not benefit from the one off adjustment to ADDERALL XR Medicaid
rebates and high level of royalties experienced in the same period last year.
The consolidation of Movetis will also mean that combined R&D and SG&A spend
for 2010 is likely to grow at marginally above 10% year on year.

Shire has made significant progress in 2010. Growth across our core
portfolio, particularly the accelerated growth of our HGT business, has
enabled us to increase our expectations of earnings while also making
targeted investments in our pipeline and international structure. We expect
to see solid earnings growth in 2011, but at a rate that reflects the pull
ahead into 2010 of some of HGT's growth potential.

PRODUCT LAUNCHES

Subject to obtaining the relevant regulatory/governmental approvals,
future product launches in the next 12 months include:

    - VYVANSE/VENVANSE for the treatment of Attention Deficit
      Hyperactivity Disorder ("ADHD") in adolescents in the US and children
      in Brazil;

    - INTUNIV as adjunctive treatment to long acting oral stimulants for the
      treatment of ADHD in children and adolescents in the US;

    - EQUASYM(R) for the treatment of ADHD in certain European
      Union ("EU") countries;

    - RESOLOR(R) in certain EU countries, for the symptomatic
      treatment of chronic constipation in women for whom laxatives fail to
      provide adequate relief;

    - LIALDA/MEZAVANT for the maintenance of remission of ulcerative colitis
      in the US and for the treatment of ulcerative colitis in
      certain countries;

    - VPRIV for the treatment of type 1 Gaucher disease in certain
      European and Latin American countries; and

    - FIRAZYR(R) for the symptomatic treatment of acute attacks of hereditary
      angioedema ("HAE") in the US and certain European and Latin American
      countries.

PRODUCT AND PIPELINE DEVELOPMENTS

Products

    PENTASA(R) - for the treatment of Ulcerative Colitis

    - On August 24, 2010 Shire received a ruling from the US Food
      and Drug Administration ("FDA") on its Citizen Petition relating to
      PENTASA. The ruling granted Shire's request with regard to the
      requirement that bioequivalence to PENTASA be shown by dissolution
      testing and further imposed a requirement for rigorous pharmacokinetic
      data. The ruling denied the request that studies with clinical outcomes
      endpoints also be required because the FDA concluded that comparative
      clinical endpoint studies would be less sensitive, accurate and
      reproducible than pharmacokinetic studies.

    RESOLOR - for the treatment of chronic constipation in women

    - Through its acquisition of Movetis, Shire has expanded its
      GI presence in Europe with the recently launched RESOLOR, a new
      chemical entity. RESOLOR is approved in the 27 countries of the EU,
      Switzerland, Iceland, Lichtenstein and Norway.

    REPLAGAL - for the treatment of Fabry disease

    - REPLAGAL is now the global market leader for the treatment
      of Fabry disease. Shire's continuing priority is to ensure long term,
      uninterrupted supply at the approved dose to patients treated with
      REPLAGAL. There are over 2,300 patients on REPLAGAL worldwide and Shire
      anticipates being able to continue to accommodate additional Fabry
      patients in 2010 while carefully monitoring supply and demand. Shire
      will be in a position to make REPLAGAL available to at least 300
      additional patients in 2011, phased throughout the year, based on
      current manufacturing capacity. Approval of the new Lexington
      Manufacturing facility will allow treatment of several hundred more
      Fabry patients with REPLAGAL, and Shire is working closely with the
      authorities towards this goal.

    VPRIV - for the treatment of Type 1 Gaucher disease

    - On August 26, 2010 the European Commission granted Shire
      marketing authorization for VPRIV, an ERT for the long-term treatment
      of Type 1 Gaucher disease. VPRIV has been authorized as an orphan
      medicine through the Centralized Procedure, making it available in 30
      countries across Europe.

    - Shire has seen rapid adoption of VPRIV worldwide. There are
      currently over 1,000 Gaucher patients treated with VPRIV and initiation
      of treatment continues. Based on its current manufacturing capacity,
      Shire anticipates being able to accommodate approximately 200
      additional Gaucher patients until the approval of the Lexington
      Manufacturing facility provides substantial additional capacity. Shire
      has an ongoing program to monitor demand and manage requests for VPRIV.
      Shire's priority is ensuring long-term, uninterrupted treatment of
      patients on therapy.

    FIRAZYR - for the treatment of HAE

    - In October 2010, Shire submitted data to support a change in
      the label in the EU to include the potential for self-administered
      subcutaneous injections of FIRAZYR in patients who are experiencing
      acute attacks of HAE.

Pipeline

This quarter we have made significant developments in our pipeline,
including:

    Collaboration with Acceleron for ActRIIB molecules

    - On September 9, 2010 Shire announced the expansion of its HGT pipeline
      through the exclusive licence, in markets outside of North America, for
      the ActRIIB class of molecules being developed by Acceleron. The
      collaboration will initially investigate ACE-031, Acceleron's lead
      ActRIIB drug candidate, which is currently in a Phase 2a trial for the
      treatment of patients with Duchenne Muscular Dystrophy. ACE-031 and
      other ActRIIB molecules have the potential to be used in other muscular
      and neuromuscular disorders with high unmet medical need.

    Pipeline obtained through Movetis acquisition

    - The acquisition of Movetis brings to Shire a promising GI pipeline,
      offering additional opportunities that include two projects in early
      clinical development and several pre-clinical leads as well as the
      rights to a large library of qualified lead compounds with potential
      for development in different GI indications.

    VYVANSE for the adjunctive therapy in the treatment of inadequate
    response in MDD

    - Today Shire announced positive results from a Phase 2 clinical trial of
      VYVANSE as adjunctive therapy for patients who have had an inadequate
      response in their treatment of MDD. Given the encouraging results and
      the promise to treat a large unmet medical need, Shire will initiate
      Phase 3 trials of VYVANSE in patients with MDD mid 2011, following
      health authority meetings to establish the development program
      parameters. Phase 2 clinical trials in additional non-ADHD indications
      (treatment of negative symptoms and cognitive impairment in
      schizophrenia and for the treatment of cognitive impairment in
      depression) remain ongoing.

    SPD535 for the treatment of arteriovenous grafts in hemodialysis patients

    - SPD535 is a novel platelet reducing agent. Phase 1 development was
      initiated in the third quarter of 2009 and is ongoing. Data from Phase
      1 clinical trials demonstrating positive proof-of-principle have been
      completed. The initial Phase 2 proof-of-concept program will target
      prevention of thrombotic complications associated with arteriovenous
      grafts in hemodialysis patients. Additional Phase 2 proof-of-concept
      clinical trials will also be initiated to assess opportunities in other
      indications.

    INTUNIV for ADHD in the EU

    - A clinical program to support the filing of a Marketing
      Authorization Approval for INTUNIV for the treatment of ADHD in
      children aged 6 to 17 in the EU has been initiated. Shire anticipates
      submission of the regulatory filing for INTUNIV in Europe will occur in
      2013.

    OTHER THIRD QUARTER AND RECENT DEVELOPMENTS

    Acquisition of Movetis

    - On September 6, 2010 Shire launched a voluntary public takeover offer
      for all the shares in Movetis, a Belgium-based speciality GI company,
      for a fully diluted equity purchase price of EUR428 million (or EUR19
      per share) in cash, equivalent to $592 million at closing of the
      transaction.

    - On October 12, 2010 the Company's wholly owned subsidiary, Shire
      Holdings Luxembourg S.a.r.l. acquired 99.21% of the shares of Movetis
      as a result of the successful tender offer. Shire is proceeding with a
      statutory squeeze-out of those shares and warrants not tendered to the
      offer in accordance with applicable Belgian legislation. An additional
      tender period opened, on the same terms, on October 12, 2010 and will
      close on November 2, 2010. Shares and warrants not tendered to the
      additional offer will transfer to Shire by operation of law on November
      8, 2010. Movetis shares will be delisted from Euronext Brussels at
      close of trading on November 2, 2010.

    Divesture of DAYTRANA

    - On August 10, 2010 Shire announced the divestiture of DAYTRANA to
      Noven. The divesture became effective on October 1, 2010. Following the
      decision to divest DAYTRANA, Shire recognised an impairment charge of
      $43 million to write-down its DAYTRANA intangible asset to its fair
      value less costs to sell.

    Co-promotion for VYVANSE with Glaxo SmithKline ("GSK")

    - In the third quarter, Shire terminated its co-promotion agreement for
      VYVANSE with GSK. Under the terms of the agreement, no termination
      payment or any other payments were made or are due to GSK since agreed
      upon sales thresholds were not achieved. The Company does not believe
      that the termination of the co-promotion agreement will impact the
      future performance of VYVANSE in the United States.

    - Following Shire's termination, GSK filed a lawsuit against Shire in the
      Philadelphia Court of Common Pleas relating to the co-promotion
      agreement. GSK is seeking compensation despite the failure to achieve
      the required sales thresholds. Shire believes that the lawsuit is
      frivolous and without merit and will vigorously defend itself.

    Paragraph IV Notice Letter for INTUNIV

    - On October 25, 2010 Shire received a Paragraph IV Notice Letter from
      Watson Pharmaceuticals, Inc. ("Watson") advising of the filing of an
      Abbreviated New Drug Application for a generic version of INTUNIV.
      Shire is currently reviewing the details of Watson's Paragraph IV
      Notice Letter which was directed to all three Orange Book listed
      patents for INTUNIV.

VYVANSE - ADHD

The increase in VYVANSE product sales was principally due to a 28%
increase in US prescription demand, from both 13% growth in the US ADHD
market and increases to VYVANSE's share of that market. Price increases taken
since Q3 2009 also contributed to the product sales growth.

Product sales growth was lower than prescription growth due to higher
sales deductions, principally increased Medicaid rebates following US
Healthcare Reform, and decreases in wholesaler inventories, or "de-stocking",
at the end of Q3 2010 (de-stocking in Q3 2010 was equivalent to $12 million
of gross sales compared to stocking of $4 million in Q3 2009).

ELAPRASE - Hunter syndrome

The growth in sales of ELAPRASE was driven by increased
volumes across all regions in which ELAPRASE is sold. On a CER basis sales
grew by 11%.

REPLAGAL - Fabry disease

The growth in REPLAGAL product sales was driven by an
acceleration of patients switching to REPLAGAL in Europe, principally due to
the ongoing supply disruption affecting the only other approved ERT for Fabry
disease. Sales increased 103% on a CER basis (REPLAGAL is sold primarily in
Euros and Pounds sterling).

LIALDA/MEZAVANT - Ulcerative colitis

Product sales for LIALDA/MEZAVANT continued to grow in Q3 2010, driven by
increased US prescription demand as a result of higher US market share and
price increases taken since Q3 2009, which were partially offset by higher
sales deductions compared to the same period in 2009.

PENTASA - Ulcerative colitis

The growth in PENTASA product sales was due to price increases taken
since Q3 2009, which more than offset lower US prescription demand.

VPRIV - Gaucher disease

Following the grant of marketing authorization from the
European Commission on August 26, 2010, VPRIV is now being sold on an
approved basis in both the US and the EU.

FOSRENOL - Hyperphosphatemia

Product sales of FOSRENOL in the EU decreased primarily due to mandatory
price reductions taken in 2010. Product sales of FOSRENOL in the US decreased
due to lower US prescription demand and higher sales deductions in Q3 2010
compared to 2009, which more than offset the effect of price increases taken
since Q3 2009.

INTUNIV - ADHD

US prescription demand for INTUNIV increased by 29% in Q3 2010
compared to Q2 2010, leading to product sales of $37 million. Product sales
in Q2 2010 of $51 million included $16 million of net sales from initial
stocking shipments made in 2009 ("Launch Stocks") which had been deferred in
accordance with Shire's accounting policy. All revenue from Launch Stocks had
been recognized by June 30, 2010.

Excluding revenue from Launch Stocks, product sales increased
by 6% in Q3 compared to Q2 2010. This increase in product sales was lower
than the growth in US prescription demand due to higher sales deductions,
principally as a result of US Healthcare Reform.

FIRAZYR - HAE

Product sales grew in line with increased volumes across
markets in Europe. FIRAZYR is the first new product for HAE in Europe in 30
years and has orphan exclusivity for acute attacks of HAE in adults in the EU
until 2018.

ADDERALL XR - ADHD

ADDERALL XR product sales increased as a result of slightly higher US
prescription demand, lower sales deductions in Q3 2010 compared to the same
period in 2009 and the effect of stocking in Q3 2010.

Sales deductions represented 60% of branded ADDERALL XR gross sales in Q3
2010 (2009: 73%). Medicaid rebates were accrued at a higher level in Q3 2009
as sales deductions for that quarter did not reflect the benefit of the
change in estimate of the Medicaid rebate liability recorded in Q4 2009.
Additionally, sales deductions in Q3 2010 were reduced following refinements
to Medicaid rebate liability estimates made in earlier quarters.

ADDERALL XR product sales in Q3 2010 also benefited from a 1% increase in
US prescription demand, as US ADHD market growth of 13% more than offset the
decline in ADDERALL XR's market share (7% in Q3 2010 compared to 8% in Q3
2009).

Royalty income increased by 27% due to higher royalties
received on sales of authorized generic versions of ADDERALL XR (royalties in
Q3 2010 were received from Impax Laboratories Inc. and in Q3 2009 were
received, at a lower rate, from Teva Pharmaceuticals Industries Ltd).
Royalties received for 3TC and Zeffix from GSK were lower in 2010 compared to
2009 as 3TC royalties continue to be adversely impacted by increased
competition from other treatments.

Cost of product sales as a percentage of product sales decreased in Q3
2010 compared to the same period in 2009 due to higher margins from existing
Core Products and the positive effect on gross margins of newly launched,
higher margin products.

R&D increased due to continued investment in a number of R&D programs,
principally VYVANSE international and investigative uses of VYVANSE for new
indications, Guanfacine Carrier Wave and other early stage development
programs.

On a US GAAP basis, R&D increased by $50.1 million over the same period
in 2009 primarily due to the up-front payment of $45.0 million made to
Acceleron on entering the licence and collaboration agreement for development
of the ActRIIB class of molecules.

    SG&A (Non GAAP)               302.4      38%    267.3      44%

SG&A increased in part due to increased sales and marketing costs
incurred to support newly launched products (INTUNIV and VPRIV) and growth in
new markets.

On a US GAAP basis, SG&A included an impairment charge of $42.7 million
to write down the DAYTRANA intangible asset to its fair value less costs to
sell following agreement to divest the product to Noven.

Reorganization costs

For the three months to September 30, 2010 Shire recorded
reorganization costs of $9.7 million (2009: $2.0 million) relating to the
transfer of manufacturing from its Owings Mills facility and the
establishment of an international commercial hub in Switzerland.

Integration and acquisition costs

For the three months to September 30, 2010 Shire recorded integration and
acquisition costs of $5.8 million (2009: $6.2 million), which in 2010 related
to the acquisition of Movetis, and in 2009 to the integration of Jerini AG.

Interest expense

For the three months to September 30, 2010 the Company incurred interest
expense of $8.3 million (2009: $9.4 million). Interest expense principally
relates to the coupon and amortization of issue costs on Shire's $1,100
million
2.75% convertible bonds due 2014.

Taxation

The US GAAP effective rate of tax in Q3 2010 was 35% (2009: 34%), and the
effective tax rate on Non GAAP income was 24% (2009: 33%).

The Non GAAP effective tax rate in both Q3 2010 and 2009 benefited from
changes in estimate of the amount of certain tax liabilities following the
submission of various tax returns. The Non GAAP effective tax rate in 2010
was lower than 2009 as the Non GAAP rate in Q3 2009 was adversely impacted by
the initial recognition of valuation allowances against certain EU deferred
tax assets and increases to accrued interest on tax contingencies, which
resulted in charges not repeated in Q3 2010.

The US GAAP effective rate of tax in Q3 2010 was 11 percentage points
higher than the Non GAAP effective tax rate as certain items excluded from
Non GAAP income, such as the up-front payment to Acceleron and the write-down
of the DAYTRANA intangible asset, were either made from territories with tax
rates lower than Shire's effective rate or in territories where the
establishment of valuation allowances precluded the recognition of any tax
benefit.

(1) For the three month period ended September 30, 2010 and for the three

(1) For the three and nine month periods ended September 30,
2010
and 2009, certain stock options have been excluded from the calculation
of diluted EPS because their exercise prices exceeded Shire plc's average
share price during the calculation period.

(2) For the three month period ended September 30, 2010 and
for the three and nine month periods ended September 30, 2009 the ordinary
shares underlying the convertible bonds have not been included in the
calculation of the diluted weighted average number of shares, as the effect
of their inclusion would be anti-dilutive.

Notes to Editors

SHIRE PLC

Shire's strategic goal is to become the leading specialty
biopharmaceutical company that focuses on meeting the needs of the specialist
physician. Shire focuses its business on attention deficit and hyperactivity
disorder, human genetic therapies and gastrointestinal diseases as well as
opportunities in other therapeutic areas to the extent they arise through
acquisitions. Shire's in-licensing, merger and acquisition efforts are
focused on products in specialist markets with strong intellectual property
protection and global rights. Shire believes that a carefully selected and
balanced portfolio of products with strategically aligned and relatively
small-scale sales forces will deliver strong results.

THE "SAFE HARBOR" STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION
REFORM ACT OF 1995

Statements included herein that are not historical facts are
forward-looking statements. Such forward-looking statements involve a number
of risks and uncertainties and are subject to change at any time. In the
event such risks or uncertainties materialize, the Company's results could be
materially adversely affected. The risks and uncertainties include, but are
not limited to, risks associated with: the inherent uncertainty of research,
development, approval, reimbursement, manufacturing and commercialization of
the Company's Specialty Pharmaceutical and Human Genetic Therapies products,
as well as the ability to secure new products for commercialization and/or
development; government regulation of the Company's products; the Company's
ability to manufacture its products in sufficient quantities to meet demand;
the impact of competitive therapies on the Company's products; the Company's
ability to register, maintain and enforce patents and other intellectual
property rights relating to its products; the Company's ability to obtain and
maintain government and other third-party reimbursement for its products; and
other risks and uncertainties detailed from time to time in the Company's

Non GAAP Measures

This press release contains financial measures not prepared in accordance
with US GAAP. These measures are referred to as "Non GAAP" measures and
include: Non GAAP operating income; Non GAAP net income; Non GAAP diluted
earnings per ADS; effective tax rate on Non GAAP income from continuing
operations before income taxes and earnings of equity method investees
("Effective tax rate on Non GAAP income"); Non GAAP cost of product sales;
Non GAAP research and development; Non GAAP selling, general and
administrative; Non GAAP other income; and Non GAAP cash generation and net
debt. These Non GAAP measures exclude the effect of certain cash and non-cash
items, both recurring and non-recurring, that Shire's management believes are
not related to the core performance of Shire's business.

These Non GAAP financial measures are used by Shire's management to make
operating decisions because they facilitate internal comparisons of Shire's
performance to historical results and to competitors' results. Shire's
Remuneration Committee uses certain key Non GAAP measures when assessing the
performance and compensation of employees, including Shire's executive
directors.

The Non GAAP measures are presented in this press release as Shire's
management believe that they will provide investors with a means of
evaluating, and an understanding of how Shire's management evaluates, Shire's
performance and results on a comparable basis that is not otherwise apparent
on a US GAAP basis, since many one-time, infrequent or non-cash items that
Shire's management believe are not indicative of the core performance of the
business may not be excluded when preparing financial measures under US GAAP.

These Non GAAP measures should not be considered in isolation from, as
substitutes for, or superior to financial measures prepared in accordance
with US GAAP.

The following items, including their tax effect, have been excluded from
both 2010 and 2009 Non GAAP earnings, and from our 2010 outlook:

    Amortization and asset impairments:

    - Intangible asset amortization and impairment charges; and
    - Other than temporary impairment of investments.

    Acquisitions and integration activities:

    - Upfront payments and milestones in respect of in-licensed and acquired
      products;
    - Costs associated with acquisitions, including transaction costs, and
      fair value adjustments on contingent consideration and acquired
      inventory; and
    - Costs associated with the integration of companies.

    Divestments, re-organizations and discontinued operations

    - Gains and losses on the sale of non-core assets;
    - Costs associated with restructuring and re-organization activities;
    - Termination costs; and
    - Income / (losses) from discontinued operations.

Depreciation, which is included in Cost of product sales, Research and
development and Selling, general and administrative costs in our US GAAP
results, has been separately disclosed for the presentation of 2009 and 2010
Non GAAP earnings. A reconciliation of Non GAAP financial measures to the
most directly comparable measure under US GAAP is presented on pages 21 to
24.

Sales growth at CER, which is a Non GAAP measure, is computed by
restating 2010 results using average 2009 foreign exchange rates for the
relevant period.

Average exchange rates for the nine months to September 30, 2010 were
$1.54:GBP1.00 and $1.32:EUR1.00 (2009: $1.54:GBP1.00 and $1.37:EUR1.00).
Average exchange rates for Q3 2010 were $1.55:GBP1.00 and $1.29:EUR1.00
(2009: $1.64:GBP1.00 and $1.43:EUR1.00).
