prospectus contained therein, and this report on Form 6-K shall be deemed a part

GENERAL

As used  herein,  "ICON",  the  "Company"  and  "we"  refer  to ICON plc and its
consolidated subsidiaries, unless the context requires otherwise.

Business

We are a contract research organization, or CRO, providing clinical research and
development services on a global basis to the pharmaceutical,  biotechnology and
medical  device  industries.  Our focus is on supporting the conduct of clinical
trials.  We have historically done so by providing such services as Phase I - IV
clinical  trials  management,   study  design,   laboratory  services  and  drug
development  support.  We believe that we are one of a select group of CROs with
the  capability  and  expertise  to  conduct   clinical  trials  in  most  major
therapeutic  areas on a global  basis.  We have  approximately  4,000  employees
worldwide, with operations in 48 locations in 30 countries, including the United
States and major markets in Europe and Rest of World.  For the nine months ended
September 30, 2006, we derived  approximately  60.7%, 32.3%, and 7.0% of our net
revenue in the United States, Europe and Rest of World, respectively.

Headquartered in Dublin,  Ireland, we began operations in 1990 and have expanded
our business through internal growth and strategic acquisitions.

On July 27, 2005 the Board of Directors of the Company  approved a change of the
Company's  fiscal  year-end  from a  twelve-month  period  ending on May 31 to a
twelve-month period ending on December 31. The Company made this change in order
to align  its  fiscal  year end with the  majority  of other  contract  research
organizations. As a requirement of this change, the Company reported results for
the  seven-month  period  from June 1, 2005 to  December  31, 2005 as a separate
transition  period in a Transition  Report  filed on Form 20-F.  From January 1,
2006,  the Company's  fiscal  quarters will end on the last day of March,  June,
September and December of each year.  Information  set out in this report is for
the  three  and nine  months  ending  September  30,  2006.  Comparative  income
statement and cash flow  information,  together with related  notes,  is for the
three  and nine  months  ending  August  31,  2005.  Comparative  balance  sheet
information and related notes are stated as at December 31, 2005.

Recent Developments

On September 29, 2006,  ICON's  shareholders  approved a bonus issue of ordinary
shares (the "Bonus Issue") to shareholders of record as of the close of business
on October 13, 2006 (the  "Record  Date").  The Bonus  Issue  provides  for each
shareholder  to receive one bonus ordinary share for each ordinary share held as
of the Record Date, effecting the equivalent of a 2-for-1 stock split. The Bonus
shares were issued on October 16, 2006 to Ordinary  Shareholders  and on October
23, 2006 to holders of American Depositary Shares ("ADSs").  NASDAQ adjusted the
trading  price of ICON's  ADSs to effect the Bonus Issue prior to the opening of
trading on October 24, 2006. All outstanding  ordinary share amounts  referenced
in the following unaudited condensed  consolidated  financial statements and the
notes  thereto  give effect to the Bonus Issue as if had occurred as of the date
referenced.

            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)
                               SEPTEMBER 30, 2006

1. Basis of Presentation

These condensed consolidated  financial statements,  which have been prepared in
accordance  with United States  generally  accepted  accounting  principles ("US
GAAP"), have not been audited. The condensed  consolidated  financial statements
reflect all adjustments,  which are, in the opinion of management,  necessary to
present a fair statement of the operating results and financial position for the
periods  presented.  The  preparation  of the condensed  consolidated  financial
statements in conformity with US GAAP requires  management to make estimates and
assumptions  that affect  reported  amounts  and  disclosures  in the  condensed
consolidated  financial  statements.  Actual  results  could  differ  from those
estimates.  As discussed in note 5, the Company adopted  Statement of Accounting
Standard ("SFAS") 123 (revised 2004) Share Based Payment ("SFAS 123R") effective
from  January 1,  2006.  There  were no other  significant  change in ICON plc's
accounting policies from those outlined in ICON's Transition Report on Form 20-F
for the seven month period ended December 31, 2005.

The condensed  consolidated  financial  statements should be read in conjunction
with the accounting policies and notes to the consolidated  financial statements
included in ICON's  Transition  Report on Form 20-F for the seven  months  ended
December 31, 2005.  Operating  results for the nine months ended  September  30,
2006 are not necessarily  indicative of the results that may be expected for the
fiscal period ending December 31, 2006.

2. Acquisitions

Acquisition of Ovation

On July 10,  2006,  the  Company  acquired  100% of the common  stock of Ovation
Healthcare Research 2 Inc. ("Ovation"),  based in Illinois,  USA, for an initial
cash consideration of U.S.$6.6 million, excluding costs of acquisition.  Working
capital  provisions have been built into the acquisition  contract requiring the
potential  payment  of  additional  deferred  consideration  up to a maximum  of
U.S.$1.4 million.

The  acquisition  of Ovation has been  accounted for as a purchase in accordance
with SFAS No. 141, "Business  Combinations".  The following table summarises the
fair values of the assets  acquired and the  liabilities  assumed at the date of
acquisition.

                                                    At July 10,

Prior Period Acquisitions

On September 9, 2003,  the Company  acquired 100% of the  outstanding  shares of
Globomax  LLC  ("GloboMax"),  based  in  Maryland,  USA,  for  an  initial  cash
consideration of $10.9 million, excluding costs of acquisition.

On May 31,  2006,  an amount of $96,131 was paid to the former  shareholders  of
GloboMax.  This $96,131 was withheld from an earn-out payment made on the August
31, 2005 due to an outstanding customer debt arising prior to the acquisition of
GloboMax.  This customer debt has subsequently been recovered and the $96,131 in
turn became due to the former  shareholders  of GloboMax.  This payment has been
accounted for as goodwill. No further payments are anticipated.

4. Net income per ordinary share

Basic net income per  ordinary  share has been  computed by dividing  net income
available to ordinary  shareholders  by the weighted  average number of ordinary
shares outstanding  during the period.  Diluted net income per ordinary share is
computed by adjusting the weighted average number of ordinary shares outstanding
during the period  for all  potentially  dilutive  ordinary  shares  outstanding
during  the period and  adjusting  net income for any  changes in income or loss
that would result from the conversion of such potential  ordinary shares.  There
is no  difference  in net  income  used for basic and  diluted  net  income  per
ordinary share.

The reconciliation of the number of shares, restated to reflect the Bonus Issue,
used in the computation of basic and diluted net income per ordinary share is as
follows:

                               Three Months Ended          Nine Months Ended

5. Stock Options

On January 17, 2003,  the Company  adopted the Share Option Plan 2003 (the "2003
Plan")  pursuant to which the  Compensation  Committee of the Company's Board of
Directors  may grant  options to officers and other  employees of the Company or
its subsidiaries for the purchase of ordinary shares. Each option will be either
an incentive stock option, or ISO, as described in Section 422 of the Code or an
employee  stock option,  or NSO, as described in Section 422 or 423 of the Code.
Each grant of an option  under the 2003 Plan will be evidenced by a Stock Option
Agreement  between the  optionee and the  Company.  The  exercise  price will be
specified in each Stock Option Agreement,  however option prices for an ISO will
not be less than 100% of the fair market value of an ordinary  share on the date
the option is granted.

An aggregate of 3.0 million  ordinary  shares have been reserved  under the 2003
Plan; in no event will the number of ordinary shares that may be issued pursuant
to options awarded under the 2003 Plan exceed 10% of the outstanding  shares, as
defined in the 2003 Plan, at the time of the grant.  Further, the maximum number
of ordinary  shares with respect to which  options may be granted under the 2003
Plan during any calendar year to any employee shall be 200,000 ordinary shares.

No options can be granted after January 17, 2013.

In December  2004, the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of  Accounting  Standards  ("SFAS") 123  (revised  2004),  Share Based
Payment  ("SFAS  123R")  which  replaced  SFAS 123  Accounting  for  Stock-Based
Compensation and supersedes  Accounting  Principles Board ("APB") Opinion No. 25
Accounting for Stock Issued to Employees.  SFAS 123R requires,  with effect from
accounting  periods beginning after June 15, 2005, that all share based payments
to employees,  including stock options  granted,  be recognized in the financial
statements based on their grant date fair values.

The  Company has adopted  SFAS 123R with effect from  January 1, 2006,  with the
Black-Scholes  method of  valuation  being used to  calculate  the fair value of
options  granted.  The Company adopted SFAS 123R using the  modified-prospective
transition method.  Under that transition method compensation cost recognized in
the nine months ended September 30, 2006,  includes;  (a) compensation  cost for
all share-based  payments granted prior to, but not yet vested as of, January 1,
2006,  based on grant date fair value  estimated in accordance with the original
provisions of SFAS 123 and (b)  compensation  cost for all share based  payments
granted subsequent to January 1, 2006, based on grant date fair values estimated
in accordance  with the provisions of SFAS 123R.  Results for prior periods have
not been restated.  The following table summarizes  option activity for the nine
months ended September 30, 2006:

Share option  awards are generally  granted with an exercise  price equal to the
market price of the Company's shares at date of grant.  Share options  typically
vest over a period of five years from date of grant and expire  eight years from
date of grant. The maximum  contractual term of options outstanding at September
30, 2006 is eight years.

The weighted  average fair value of stock options granted during the nine months
ended  September 30, 2006,  calculated  using the  Black-Scholes  option pricing
model, was $9.82 based on the following  assumptions;  dividend yield - 0%, risk
free  interest  rate - 4.6%,  expected  volatility  - 45% and  weighted  average
expected life - 4.81 years.

On January 17, 2006,  30,000 share  options,  with an exercise  price of $20.84,
were granted to a key employee of the Company.  These  options will vest between
2009 and 2014,  subject to the Company's  diluted  earnings  achieving $2.10 per
share.  If the  Company  does not  achieve  diluted  earnings of $2.10 per share
before January 16, 2014, the option grant expires.

Expected volatility is based on historical volatility of our common stock over a
period equal to the expected term of the options;  the expected life  represents
the  weighted  average  period of time that  options  granted are expected to be
outstanding  given  consideration  to  vesting  schedules,  and  our  historical
experience of part vesting and termination patterns. The risk-free rate is based
on the U.S. gilts zero-coupon yield curve in effect at time of grant for periods
corresponding with the expected life of the option.

Income from  operations for the nine months ended  September 30, 2006, is stated
after charging $3.0 million in respect of non-cash stock  compensation  expense.
Basic and diluted  earnings  per share for the nine months ended  September  30,
2006,  had SFAS  123R not been  introduced  would  have  been  $1.06  and  $1.03
respectively.  Non-cash  stock  compensation  expense for the nine months  ended
September 30, 2006, has been allocated to direct costs and selling,  general and
administrative expenses as follows:

As at  September  30,  2006,  total  unrecognized  compensation  cost related to
unvested options, which the Company expects to recognize over a weighted average
period of 4.3 years,  amounted to $10.1 million. The Company has granted options
with fair values  ranging  from $5.78 to $9.82 per option or a weighted  average
fair value of $7.94 per option.  The Company issues new ordinary  shares for all
options exercised. The total amount of fully vested share options which remained
outstanding  at September 30, 2006 was 68,396.  The fully vested options have an
average  remaining  contractual term of 1.76 years and average exercise price of
$10.27.  The total  intrinsic value of options  exercised  during the period was
$5.94 million (3 months ended September 30, 2006 was $2.34 million).

Prior to the adoption of SFAS 123R, the Company  accounted for its share options
in accordance  with the  provisions  of SFAS No. 123 which  allowed  entities to
continue to apply the  provisions of APB 25 and provide pro forma net income and
pro forma earnings per share  disclosures for employee stock option grants as if
the fair-value-based method defined in SFAS No. 123 had been applied. The impact
on net profit and earnings per share, had SFAS 123R been applied are as follows:

The weighted  average fair value of stock options granted during the nine months
ended August 31, 2005,  calculated using the Black-Scholes option pricing model,
was $7.54 based on the  following  assumptions;  dividend  yield - 0%, risk free
interest  rate -  3.9/4.1%,  expected  volatility  - 45%  and  weighted  average
expected life - 4.81 years.

Expected volatility is based on historical volatility of our common stock over a
period equal to the expected term of the options;  the expected life  represents
the  weighted  average  period of time that  options  granted are expected to be
outstanding given consideration to vesting schedules and our historical exercise
and  termination  patterns.  The  risk-free  rate is  based  on the  U.S.  gilts
zero-coupon  yield  curve in effect at time of grant for  periods  corresponding
with the expected life of the option.

On February 7, 2005,  240,000 share  options,  with an exercise price of $17.20,
were granted to certain key  employees of the Company.  These  options will vest
between 2008 and 2013 subject to the Company's diluted earnings  achieving $2.00
per share. If the Company does not achieve  diluted  earnings of $2.00 per share
before February 6, 2013, the option grant expires.

ICON plc


Management's Discussion and Analysis of Financial Condition and Results of
Operations.

The following  discussion and analysis  should be read in  conjunction  with the
unaudited  Condensed  Consolidated  Financial  Statements and accompanying notes
included elsewhere herein and the Consolidated  Financial Statements and related
notes  thereto  included  in our  Transition  Report  on Form 20-F for the seven
months ended December 31, 2005. The Consolidated  Financial Statements have been
prepared in accordance  with  accounting  principles  generally  accepted in the
United States.

Overview

We are a contract research organization, or CRO, providing clinical research and
development services on a global basis to the pharmaceutical,  biotechnology and
medical  device  industries.  Our focus is on supporting the conduct of clinical
trials.  We have historically done so by providing such services as Phase I - IV
clinical  trials  management,   study  design,   laboratory  services  and  drug
development  support.  We believe that we are one of a select group of CROs with
the  capability  and  expertise  to  conduct   clinical  trials  in  most  major
therapeutic  areas on a global  basis.  We have  approximately  4,000  employees
worldwide,  with operations in 48 locations in 30 countries including the United
States and major markets in Europe and Rest of World.  For the nine months ended
September 30, 2006, we derived  approximately  60.7%, 32.3%, and 7.0% of our net
revenue in the United States, Europe and Rest of World, respectively.

We earn  revenues by  providing a number of  different  services to our clients.
These  services  include  clinical  trials  management,   biometric  activities,
consulting  and  laboratory  services.  We recognize  biometric,  consulting and
laboratory revenues on a fee-for-service basis. Our laboratory service contracts
are multiple element  arrangements,  with laboratory kits and laboratory testing
representing  the contractual  elements.  We determine the fair values for these
elements, each of which can be sold separately,  based on objective and reliable
evidence of their respective fair values. Our laboratory contracts entitle us to
receive  non-refundable  set up fees and we  allocate  such  fees as  additional
consideration to the contractual elements based on the proportionate fair values
of the  elements.  We  recognize  revenues  for the elements on the basis of the
number of deliverable units completed in a period.

We recognize  clinical trials revenue on the basis of the  relationship  between
time  incurred  and  the  total  estimated  duration  of the  contract,  as this
represents the most accurate pattern over which our contractual  obligations are
fulfilled.  We invoice our customers upon  achievement of specified  contractual
milestones.  This  mechanism,  which  allows  us to  receive  payment  from  our
customers throughout the duration of the contract,  is not reflective of revenue
earned.  We  recognize  revenues  over  the  period  from  the  awarding  of the
customer's  contract to study  completion  and  acceptance.  This requires us to
estimate total expected revenue, time inputs, contract costs,  profitability and
expected   duration  of  the  clinical  trial.   These  estimates  are  reviewed
periodically and, if any of these estimates change or actual results differ from
expected  results,  an adjustment is recorded in the period in which they become
readily estimable.

As  is  customary  in  the  CRO  industry,   we  subcontract  with  third  party
investigators in connection with clinical trials.  All subcontractor  costs, and
certain  other  costs where  reimbursed  by clients,  are,  in  accordance  with
industry practice,  deducted from gross revenue to arrive at net revenue.  As no
profit is earned on these costs,  which vary from contract to contract,  we view
net revenue as our primary measure of revenue growth.

Direct costs consist  primarily of compensation  and associated  fringe benefits
for  project-related  employees and other direct project driven costs.  Selling,
general and  administrative  expenses consist of compensation and related fringe
benefits  for  selling  and  administrative  employees,  professional  services,
advertising costs and all costs related to facilities and information systems.

As the nature of our  business  involves  the  management  of projects  having a
typical  duration  of  one  to  three  years,  the   commencement,   completion,
curtailment  or  early  termination  of  projects  in a  fiscal  year can have a
material impact on revenues  earned with the relevant  clients in such years. In
addition,  as we typically work with some,  but not all,  divisions of a client,
fluctuations  in the  number  and  status  of  available  projects  within  such
divisions can also have a material  impact on revenues  earned from such clients
from year to year.

Although  domiciled  in  Ireland,  we report our results in U.S.  dollars.  As a
consequence,  the  results  of our  non-United  States  based  operations,  when
translated into U.S.  dollars,  could be materially  affected by fluctuations in
exchange rates between the U.S. dollar and the currency of those operations.


                                       14



In  addition  to  translation  exposures,  we are also  subject  to  transaction
exposures  because the currency in which  contracts  are priced can be different
from the currencies in which costs relating to those contracts are incurred.  We
have 17 operations  operating in U.S. dollars, 6 in Euros, 3 in pounds Sterling,
and 1 each in Australian dollars,  Singapore dollars,  Yen, Israeli New Shekels,
Latvian Lats,  Swedish Krona,  Argentine Peso, South African Rand, Indian Rupee,
Russian Rouble,  Canadian dollar,  Hungarian  Forint,  Polish Zloty,  Lithuanian
Litas, Hong Kong dollar,  Taiwan dollar,  Mexican Peso,  Brazilian Real, Chilean
Peso,  South Korean Won,  Chinese Yuan Renminbi and Thai Baht. Our operations in
the United States are not materially exposed to such currency differences as the
majority of our revenues  and costs are in U.S.  dollars.  However,  outside the
United States the  multinational  nature of our activities  means that contracts
are  usually  priced in a single  currency,  most often  pounds  Sterling,  U.S.
dollars or Euros, while costs arise in a number of currencies,  depending, among
other things,  on which of our offices  provide staff for the contract,  and the
location of investigator  sites.  Although many such contracts benefit from some
degree of natural hedging due to the matching of contract  revenues and costs in
the same  currency,  where costs are incurred in currencies  other than those in
which  contracts  are  priced,  fluctuations  in the  relative  value  of  those
currencies  could  have a  material  effect on our  results  of  operations.  We
regularly  review our  currency  exposures  and hedge a portion of these,  using
forward exchange contracts, where natural hedges do not cover them.

We have received  capital and revenue grants from Enterprise  Ireland,  an Irish
government  agency.  We record  capital  grants as  deferred  income,  which are
credited to income on a basis  consistent with the  depreciation of the relevant
asset.  Grants relating to operating  expenditures are credited to income in the
period in which the related expenditure is charged. The capital grant agreements
provide that in certain  circumstances  the grants received may be refundable in
full. These circumstances include sale of the related asset,  liquidation of the
Company or failing to comply in other  respects with the grant  agreements.  The
operating  expenditure  grant  agreements  provide for repayment in the event of
downsizing  of the Company  calculated by reference to any reduction in employee
numbers.  We have not recognized any loss contingency  having assessed as remote
the  likelihood  of these  events  arising.  Up to September  30, 2006,  we have
received  $2,477,579  and  $1,841,504  under the  capital  grants and  operating
grants,  respectively.  Pursuant  to the terms of the grant  agreements,  we are
restricted  from  distributing  some of  these  amounts  by way of  dividend  or
otherwise.

As we conduct  operations on a global basis, our effective tax rate has depended
and will depend on the geographic distribution of our revenue and earnings among
locations  with varying tax rates.  Our results of  operations  therefore may be
affected  by  changes  in  the  tax  rates  of  the  various  jurisdictions.  In
particular, as the geographic mix of our results of operations among various tax
jurisdictions changes, our effective tax rate may vary significantly from period
to period.

Net revenue  increased by $34.8  million,  or 40.5%,  from $85.9 million for the
three months ended August 31, 2005, to $120.7 million for the three months ended
September 30, 2006.  This  improvement  arose through a combination of increased
business  from existing  clients,  business won from new clients and revenues of
$2.6 million from acquisitions not included in the comparative period.

                                       15



Revenues in the United States, Europe and the Rest of World grew by 52.2%, 24.6%
and 33.1%  respectively.  In the three months  ended  September  30,  2006,  net
revenue  from our central  laboratory  business  increased  by 78.1%,  from $7.2
million,  to $12.9 million,  while our clinical  research segment grew by 37.0%,
from $78.7 million, to $107.8 million, in each case over the period ended August
31,  2005.  The  increase in net revenue in our  central  laboratory  segment is
primarily due to higher testing volumes over the comparative  period. The growth
in net revenue in our clinical  research  segment is due to the expansion of our
services to both existing and new clients,  increased use of  outsourcing by the
pharmaceutical,  biotechnology  and medical  device  industries,  an  underlying
increase in research and development spending, consolidation in the CRO industry
and revenues from acquisitions not included in the comparative period.

Direct costs  increased by $21.1 million,  or 44.6%,  from $47.3 million for the
three months  ended August 31, 2005 to $68.4  million for the three months ended
September 30, 2006,  primarily due to increased  staff numbers needed to support
increased  project  related  activity,  the inclusion of $0.57 million  non-cash
stock  compensation  expense for the quarter  ended  September  30, 2006 and the
direct costs from  acquisitions  of $1.5 million not included in the comparative
period. Direct costs as a percentage of net revenue increased from 55.1% for the
three months ended  August 31, 2005,  to 56.7% for three months ended  September
30, 2006.

Selling,  general and  administrative  expenses  increased by $9.0  million,  or
33.5%,  from $26.8  million for the three months ended August 31, 2005, to $35.8
million for the three months ended  September 30, 2006.  This increase is due to
the  continued  expansion of our  operations,  the  inclusion  of $0.47  million
non-cash  stock  compensation  expense and the costs from  acquisitions  of $0.6
million not included in the comparative  period. As a percentage of net revenue,
selling, general and administrative expenses,  decreased from 31.2% in the three
months ended August 31, 2005,  to 29.7% in the three months ended  September 30,
2006.

Depreciation and amortization  expense increased by $0.4 million, or 12.8%, from
$3.4 million for the three months ended August 31, 2005, to $3.8 million for the
three months ended  September  30, 2006.  This  increase is due to the continued
investment in  facilities  and  information  technology to support the growth in
activity and in providing  for future  capacity  and costs from  acquisition  of
$0.03  million  included  in the  comparative  period.  As a  percentage  of net
revenue,  depreciation and amortization  decreased from 4.0% in the three months
ended August 31, 2005, to 3.2% in the three months ended September 30, 2006.

Income from operations  increased by $4.2 million,  or 50.7%,  from $8.4 million
for the three  months  ended  August 31,  2005,  to $12.6  million for the three
months ended September 30, 2006. The operating income for the quarter is derived
after  the  recognition  of the non  cash  stock  compensation  charge  of $1.03
million.  There was no such charge in the comparable  period. As a percentage of
net revenue,  income from  operations  increased  from 9.7% for the three months
ended  August 31,  2005,  to 10.4% of net  revenues  for the three  months ended
September 30, 2006.

The three months ended  September 30, 2006,  saw a continued  improvement in the
performance of the central laboratory business, from a loss from operations,  as
a percentage of net revenue of 22.3% for the three months ended August 31, 2005,
to an operating  profit of 5.0% for the three months ended  September  30, 2006.
The central laboratory constitutes  approximately 10.7% of our business revenues
for the three  months  ended  September  30,  2006.  Operating  margins  for our
clinical research segment decreased from 12.7% for the three months ended August
31, 2005, to 11.1% for the three months ended September 30, 2006.

Interest  income for the three months ended September 30, 2006 was $1.0 million,
an increase  of $0.6  million  over the amount of interest  income for the three
months ended August 31, 2005.  Higher average level of funds invested and higher
interest  rates over the prior  period  contributed  to the  increased  interest
income.

ICON's  effective  tax rate for the three  months ended  September  30, 2006 was
25.2%  compared  with 28.0% for the three  months  ended  August 31,  2005.  The
decrease is due mainly to the changes in the geographic  distribution of pre-tax
earnings.

Net revenue increased by $71.9 million, or 28.2%, from $254.7 million for the
nine months ended August 31, 2005, to $326.6 million for the nine months ended
September 30, 2006. This improvement arose through a combination of increased
business from existing clients and business won from new clients. Revenues in
the United States, Europe and the Rest of World grew by 39.0%, 9.3% and 47.2%
respectively. In the nine months ended September 30, 2006, net revenue from our
central laboratory business increased by 70.8%, from $19.7 million for the nine
months ended August 31, 2005, to $33.7 million for the nine months ended
September 30, 2006, while our clinical research segment grew by 24.7%, from
$235.0 million, to $292.9 million over the comparable period. The increase in
net revenue in our central laboratory segment is primarily due to higher testing
volumes in 2006. The growth in net revenue in our clinical research segment is
due to the expansion of our services to both existing and new clients, increased
use of outsourcing by the pharmaceutical, biotechnology and medical device
industries, an underlying increase in research and development spending, revenue
from acquisitions and consolidation in the CRO industry.

Direct costs increased by $42.3 million, or 30.0%, from $140.8 million for the
nine months ended August 31, 2005, to $183.1 million for the nine months ended
September 30, 2006, primarily due to increased staff numbers needed to support
increased project related activity and the inclusion of $1.65 million non-cash
stock compensation. Direct costs as a percentage of net revenue increased from
55.3% in the nine months ended August 31, 2005, to 56.1% in the nine months
ended September 30, 2006.

Selling, general and administrative expenses increased by $16.7 million, or
20.5%, from $81.7 million for the nine months ended August 31, 2005, to $98.5
million for the nine months ended September 30, 2006. This increase is due to
the continued expansion of our operations and the inclusion of $1.34 million
non-cash stock compensation expense. As a percentage of net revenue, selling,
general and administrative expenses, decreased from 32.1% in the nine months
ended August 31, 2005, to 30.1% in the nine months ended September 30, 2006.

Depreciation and amortization expense increased by $0.6 million, or 5.8%, from
$10.4 million for the nine months ended August 31, 2005, to $11.0 million for
the nine months ended September 30, 2006. This increase is due to the continued
investment in facilities and information technology to support the growth in
activity and in providing for future capacity. As a percentage of net revenue,
depreciation and amortization, decreased from 4.1% in the nine months ended
August 31, 2005, to 3.4% in the nine months ended September 30, 2006.

Other charges of $11.3 million were recognised in the nine months ended August
31, 2005. These charges related to the recognition of an impairment in the
carrying value of our investment in the central laboratory, a write down of
certain fixed assets and the lease termination and exit costs associated with
the consolidation of some of our office facilities in the U.S.

                                       17



Income from operations increased by $23.5 million, or 224.5%, from $10.5 million
for the nine months ended August 31, 2005,  to $34.0 million for the nine months
ended September 30, 2006. As a percentage of net revenue, income from operations
increased  from 4.1% for the nine months ended August 31, 2005,  to 10.4% of net
revenues for the nine months ended September 30, 2006. The operating  income for
the  nine  months  is  derived  after  the  recognition  of the non  cash  stock
compensation charge of $3.0 million.  There was no such charge in the comparable
period.  As a percentage of net revenue,  losses from operations for the central
laboratory  decreased from 71.7% for the nine months ended August 31, 2005, to a
profit from  operations  percentage of 1.0% for the nine months ended  September
30, 2006, due to the efficiencies gained in the higher testing volumes in fiscal
2006.  For the nine months  ended  September  30, 2006,  the central  laboratory
constituted approximately 10.3% of our business revenues.  Operating margins for
our  clinical  research  segment  increased  from 10.5% in the nine months ended
August 31, 2005, to 11.5% for the nine months ended September 30, 2006.

Interest  income for the nine months ended  September 30, 2006 was $2.6 million,
an increase  of $1.5  million  over the amount of  interest  income for the nine
months ended August 31, 2005.  Higher average level of funds invested and higher
interest  rates over the prior  period  contributed  to the  increased  interest
income.

ICON's effective tax rate for the nine months ended September 30, 2006 was 26.0%
compared  with 40.6% for the nine months ended August 31, 2005.  The decrease in
the effective  rate was primarily due to the inclusion of once-off other charged
for the nine months ended August 31, 2005.

Liquidity and Capital Resources

The CRO industry  generally is not capital  intensive.  Since our inception,  we
have  financed  our  operations  and  growth  primarily  with  cash  flows  from
operations,  net proceeds of $49.1 million raised in our initial public offering
in May 1998 and net proceeds of $44.3 million  raised in our public  offering in
August 2003.  Our  principal  cash needs are payment of salaries,  office rents,
travel  expenditures  and payments to  subcontractors.  The aggregate  amount of
employee  compensation paid in the nine months ended September 30, 2006 amounted
to $196.0  million,  compared to $152.9 million for the nine months ended August
31, 2005.  Investing  activities  primarily  reflect  capital  expenditures  for
facilities and for information  systems  enhancements,  the sale and purchase of
short-term investments and acquisitions.

Our clinical  research and development  contracts are generally fixed price with
some  variable  components  and range in  duration  from a few months to several
years.  Revenue from contracts is generally recognized as income on the basis of
the relationship between time incurred and the total estimated contract duration
or on a fee-for-service  basis. The cash flow from contracts  typically consists
of a down  payment  of  between  10% and 20% paid at the time  the  contract  is
entered into, with the balance paid in instalments over the contract's  duration
and in some cases upon the achievement of certain milestones.  Accordingly, cash
receipts do not necessarily  correspond to costs incurred and revenue recognized
on contracts.

As of  September  30,  2006,  our working  capital  amounted to $153.5  million,
compared to $132.3 million at December 31, 2005. The other significant influence
on our operating  cash flow is revenue  outstanding,  which  comprises  accounts
receivable and unbilled revenue,  less payments on account. The dollar values of
these  amounts  and the related  days  revenue  outstanding  can vary due to the
achievement of  contractual  milestones,  including  contract  signing,  and the
timing of cash receipts.  The number of days revenue  outstanding was 57 days at
September 30, 2006, compared to 65 days at December 31, 2005.

Net cash provided by operating  activities  was $33.0 million in the nine months
ended  September  30, 2006,  compared to $30.0  million in the nine months ended
August 31, 2005.

Net cash used in investing activities was $42.9 million in the nine months ended
September 30, 2006, compared to $4.5 million in the nine months ended August 31,
2005,  due to purchase of short term  investments  and  acquisitions  during the
period.

Net cash  provided by financing  activities  was $5.0 million in the nine months
ended  September  30,  2006,  compared to $8.1  million  used in the nine months
ended,  August 31, 2005,  primarily due to repayment of bank credit lines in the
comparative period ended September 30, 2006.

As a result of these cash flows,  cash and cash  equivalents  decreased  by $4.6
million in the nine months ended September 30, 2006,  compared to an increase of
$16.3 million in the nine months ended August 31, 2005.

Inflation

We believe the effects of  inflation  generally  do not have a material  adverse
impact on our operations or financial conditions.

Legal Proceedings

We are not party to any  litigation or other legal  proceedings  that we believe
could  reasonably be expected to have a material adverse effect on our business,
results of operations and financial condition.
