PART I

                                 CARILLION PLC

              RECOMMENDED FINAL REVISED CASH AND SHARE ACQUISITION

                                       OF

                                   MOWLEM PLC


On 7 December 2005 the Boards of Carillion and Mowlem announced the terms of a
recommended proposal made by Carillion to acquire, for cash and shares, the
entire issued and to be issued share capital of Mowlem.



The Boards of Carillion and Mowlem are now pleased to announce that agreement
has been reached on final revised terms for the Acquisition of the entire issued
and to be issued share capital of Mowlem by Carillion.  The Acquisition is to be
implemented by means of a scheme of arrangement under section 425 of the
Companies Act and is unanimously recommended by the Mowlem Board.



Highlights

*         The final revised terms of the recommended cash and share Acquisition value each Mowlem
          share at 220 pence

*         Consideration for each Mowlem Share is 0.46 New Carillion Shares valued at 138 pence (based
          on the Closing Price of a Carillion Share on 14 December 2005, the last practicable date
          prior to this announcement) and 82 pence in cash, with a Mix and Match Facility being made
          available

*         Irrevocable undertakings have been received from Mowlem Shareholders in respect of
          40,780,576 Mowlem Shares, representing approximately 28.7 per cent. of the existing issued
          share capital of Mowlem

*         In addition, letters of intent have been received from Mowlem Shareholders such that
          irrevocable undertakings and letters of intent have been received in respect of, in
          aggregate, 49,060,192 Mowlem Shares, representing approximately 34.5 per cent. of the
          existing issued share capital of Mowlem

*         Enlarged Group expected to achieve an annual running rate of cost savings of £15 million by
          the end of 2007 (the first full year after completion of the Acquisition) and the
          Acquisition is expected to be materially earnings enhancing in that year (see Note)

*         Cost savings are expected to arise as follows:

          -        approximately one third from the restructuring of head office and rationalisation
                   of regional properties;

          -        approximately one third from improved supply chain management; and

          -        the remainder from savings in support functions, insurances, property and other
                   costs (see Note).

*         Carillion management has a strong track record within its existing business of delivering
          substantial savings in the same areas

*         Holders of New Carillion Shares following completion of the Acquisition will receive the
          Carillion final dividend for the year to 31 December 2005 which, in the absence of
          unforeseen circumstances, is expected to be not less than 5 pence per Carillion Share

*         Acquisition price of 220 pence represents a premium of approximately 41 per cent. to the
          average Closing Price of 156 pence for each Mowlem Share for the three months prior to and
          including 28 October 2005, the last Business Day prior to the day of the announcement by
          Mowlem that it had received an approach

*         The terms set out in this announcement are Carillion's final proposal and will not be
          further improved, save that Carillion continues to reserve the right, in its sole
          discretion, to implement the Acquisition by way of a takeover offer rather than by way of
          the Scheme and to make appropriate amendments to the terms of the Acquisition in order to do
          so



Commenting on the revised terms of the Proposed Acquisition, Philip Rogerson,
Chairman of Carillion said:



'We are delighted to have secured such substantial support from Mowlem
shareholders for this revised proposal.  This transaction will create a leading
support services and construction company and we are confident that it will
deliver excellent value for both Mowlem and Carillion shareholders.'



Commenting on the revised terms of the Proposed Acquisition, Joe Darby, Chairman
of Mowlem said:



'I am very pleased to be able to recommend this improved final offer from
Carillion.  I firmly believe that the combination of Mowlem and Carillion will
create a strong company and that Mowlem shareholders will derive significant
value.'



Lazard is acting as financial adviser to Carillion.  Morgan Stanley and Oriel
Securities are acting as joint corporate brokers to Carillion.



Rothschild is acting as financial adviser to Mowlem.  Hoare Govett is acting as
corporate broker to Mowlem.



This summary should be read in conjunction with, and is subject to, the full
text of the following announcement.  In particular, the Acquisition is subject
to the conditions set out in Part II of this announcement.


Note     The anticipated operational cost savings have been calculated on the basis of the existing cost
         and operating structures of the Carillion and Mowlem Groups.  These statements of estimated cost
         savings and one-off costs for achieving them relate to future actions and circumstances which,
         by their nature, involve risks, uncertainties and other factors.  Because of this, the cost
         savings referred to may not be achieved, or those achieved could be materially different from
         those estimated.

         The statements that the Acquisition is expected to be materially earnings enhancing for
         Carillion in 2007 (the first full year following completion of the Acquisition) relate to future
         actions and circumstances, which, by their nature, involve risks, uncertainties and other
         factors.

         These statements do not constitute a profit forecast and should not be interpreted to mean that
         earnings for that year or any subsequent financial period would necessarily match or be greater
         than those for any preceding financial period.

Dealing Restrictions



Under the provisions of Rule 8.3 of the City Code on Takeovers and Mergers (the
'Code'), if any person is, or becomes, 'interested' (directly or indirectly) in
1% or more of any class of 'relevant securities' of Carillion or of Mowlem, all
'dealings' in any 'relevant securities' of that company (including by means of
an option in respect of, or a derivative referenced to, any such 'relevant
securities') must be publicly disclosed by no later than 3.30pm (London time) on
the London business day following the date of the relevant transaction.  This
requirement will continue until the date on which the offer becomes, or is
declared, unconditional as to acceptances, lapses or is otherwise withdrawn or
on which the 'offer period' otherwise ends.  If two or more persons act together
pursuant to an agreement or understanding, whether formal or informal, to
acquire an 'interest' in 'relevant securities' of Carillion or Mowlem, they will
be deemed to be a single person for the purpose of Rule 8.3.



Under the provisions of Rule 8.1 of the Code, all 'dealings' in 'relevant
securities' of Carillion or Mowlem by Carillion or Mowlem, or by any of their
respective 'associates' must be disclosed by no later than 12.00 noon (London
time) on the London business day following the date of the relevant transaction.



A disclosure table, giving details of the companies in whose 'relevant
securities' 'dealings' should be disclosed, and the number of such securities in
issue, can be found on the Panel's website at www.thetakeoverpanel.org.uk.



'Interests in securities' arise, in summary, when a person has long economic
exposure, whether conditional or absolute, to changes in the price of
securities.  In particular, a person will be treated as having an 'interest' by
virtue of the 'ownership' or control of securities, or by virtue of any option
in respect of, or derivative referenced to, securities.



Terms in quotation marks are defined in the Code, which can also be found on the
Panel's website.  If you are in any doubt as to whether or not you are required
to disclose a 'dealing' under Rule 8, you should consult the Panel.

This announcement does not constitute an offer to sell or invitation to purchase
any securities or the solicitation of any vote for approval in any jurisdiction,
nor shall there be any sale, issue or transfer of the securities referred to in
this announcement in any jurisdiction in contravention of applicable law.



The release, publication or distribution of this announcement in certain
jurisdictions may be restricted by law.  The availability of the New Carillion
Shares and the Mix and Match Facility under the terms of the Scheme (or, if the
offer is implemented by way of a takeover offer, of that offer), if made, to
persons not resident in the United Kingdom may be affected by the laws of the
relevant jurisdictions in which they are located.  Persons who are not resident
in the United Kingdom or who are subject to other jurisdictions should inform
themselves of, and observe, any applicable requirements.



This announcement is not an offer of securities for sale in the US and the New
Carillion Shares have not been, and will not be, registered under the US
Securities Act of 1933 (the 'Securities Act') or under the securities laws of
any state, district or other jurisdiction of the US, Australia, Canada or Japan
and no regulatory clearance in respect of the New Carillion Shares has been, or
will be, applied for in any jurisdiction other than the UK.   It is expected
that the New Carillion Shares will be issued in reliance upon the exemption from
the registration requirements of the Securities Act provided by Section 3(a)
(10) thereof.  Under applicable US securities laws, Mowlem Shareholders who are
or will be deemed to be 'affiliates' of Mowlem or Carillion prior to, or of
Carillion after, the Effective Date will be subject to certain transfer
restrictions relating to the New Carillion Shares received in connection with
the Acquisition.



If the Acquisition is carried out by way of a takeover offer, it will not be
made, directly or indirectly, in or into the United States, Canada, Australia or
Japan and will not be capable of acceptance from or within the United States,
Canada, Australia or Japan.  Accordingly, copies of this announcement and all
documents relating to the takeover offer will not be, and must not be, mailed or
otherwise forwarded, distributed or sent in, into or from the United States,
Canada, Australia or Japan.  If the Acquisition is carried out by way of
takeover offer, the New Carillion Shares to be issued in connection with such
takeover offer will not be registered under the Securities Act or under the
securities laws of any state, district or jurisdiction of the United States and
may not be offered, sold or delivered, directly or indirectly, in the United
States, other than pursuant to an exemption from any such registration
requirements.  Carillion does not intend to register any such takeover offer or
any part thereof in the United States or to conduct a public offering of the New
Carillion Shares in the United States.



Whether or not a Mowlem Shareholder's Mowlem Shares are voted at the Scheme
Meeting or the Mowlem Extraordinary General Meeting, if the Scheme becomes
Effective, those Mowlem Shares will be acquired pursuant to the Scheme and
Mowlem Shareholders will, subject to the Mix and Match Facility, receive a
payment of 82 pence in cash and 0.46 New Carillion Shares for every Mowlem
Share.



Mowlem will prepare the Scheme Document to be distributed to Mowlem
Shareholders.  Carillion and Mowlem urge Mowlem Shareholders to read the Scheme
Document when it becomes available because it will contain important information
relating to the Acquisition.  Mowlem Shareholders may obtain a further free copy
of the Scheme Document, when it becomes available, from Macfarlanes.

PART II


                                 CARILLION PLC

              RECOMMENDED FINAL REVISED CASH AND SHARE ACQUISITION

                                       OF

                                   MOWLEM PLC

1.       Introduction



On 7 December 2005, the Boards of Carillion and Mowlem announced the terms of a
recommended proposal made by Carillion to acquire, for cash and shares, the
entire issued and to be issued share capital of Mowlem.



The Boards of Carillion and Mowlem are now pleased to announce that agreement
has been reached on final revised terms of the Acquisition of the entire issued
and to be issued share capital of Mowlem by Carillion.  The final revised terms
of the Acquisition value each Mowlem Share at 220 pence and Mowlem's existing
issued share capital at approximately £313 million.



The Acquisition is to be implemented by means of a scheme of arrangement under
section 425 of the Companies Act and is unanimously recommended by the Mowlem
Board.  Carillion reserves the right, in its sole discretion, to implement the
Acquisition by making a takeover offer for the entire issued and to be issued
share capital of Mowlem and to make appropriate amendments to the terms of the
Acquisition in order to do so.  Otherwise, the terms set out in this
announcement are Carillion's final proposal and will not be further improved.


2.       The Revised Terms of the Acquisition



Under the terms of the Scheme, which will be subject to the conditions and
further terms set out in Appendix I of this announcement and the full terms and
conditions that will be set out in the Scheme Document, Mowlem Shareholders will
be entitled to receive:


                   for each Mowlem Share            0.46 New Carillion Shares
                                                    and
                                                    82 pence in cash



and so in proportion for any number of Mowlem Shares held.  Based on the Closing
Price of a Carillion Share immediately prior to this announcement, this
entitlement represents 138 pence in New Carillion Shares plus 82 pence in cash.



A Mix and Match Facility will also be made available pursuant to which Mowlem
Shareholders may, subject to availability, elect to vary the proportions in
which they receive New Carillion Shares and cash in respect of their holdings of
Mowlem Shares.  Further details of the Mix and Match Facility are set out in
paragraph 5 below.


3.       Irrevocable Undertakings



Mowlem Directors who also hold Scheme Shares have irrevocably undertaken to vote
such Scheme Shares (in aggregate, 46,193 Mowlem Shares, representing
approximately 0.033 per cent. of the existing issued share capital of Mowlem) in
favour of the Acquisition and the Scheme at the Scheme Meeting and the Mowlem
Extraordinary General Meeting.  Such Mowlem Directors have also undertaken that,
if following this announcement, Carillion decides to implement the Acquisition
by means of a takeover offer instead of by way of the Scheme, that such Mowlem
Directors shall accept such takeover offer in respect of their Scheme Shares.



In addition, irrevocable undertakings to vote in favour of the Scheme and the
Acquisition at the Scheme Meeting and the Mowlem Extraordinary General Meeting
have been received from Schroder Investment Management Limited in respect of
17,373,714 Mowlem Shares, from Societe Generale Asset Management in respect of
16,133,470 Mowlem Shares and from Aberforth Partners LLP in respect of 7,227,199
Mowlem Shares.



Separately, a non-legally binding letter of intent has been received from Morley
Fund Management in respect of 8,279,616 Mowlem Shares.



Accordingly, Carillion has received irrevocable undertakings on the terms set
out above and letters of intent in respect of, in aggregate, 49,060,192 Mowlem
Shares, representing approximately 34.5 per cent. of Mowlem's existing issued
share capital.



The irrevocable undertakings referred to above given by certain Mowlem Directors
will cease to be binding on, amongst other occurrences, (a) the Mowlem Directors
determining not to recommend, or withdrawing their recommendation of, the
Acquisition, (b) if the Acquisition is to be implemented by the Scheme, the
Scheme failing to become Effective or (c) if the Acquisition is to be
implemented by means of a takeover offer, if such takeover offer lapses or is
withdrawn.



The irrevocable undertaking referred to above given by Schroder Investment
Management Limited will remain binding in the event of a competing offer being
made for Mowlem but will cease to be binding if the Scheme fails to become
Effective.  Under the irrevocable undertaking referred to above given by Societe
Generale Asset Management, Societe Generale Asset Management retains the right
to accept a higher competing offer made for Mowlem Shares which represents an
improvement of not less than the higher of 10 per cent. above the value of
Carillion's offer on (a) the day of this announcement and (b) the day of
announcement of a competing bid, in each case using the average Closing Price of
a Carillion Share on each of the five business days before the relevant
announcement.  Each of these irrevocable undertakings will also cease to be
binding in relation to any Mowlem Shares held by Schroder Investment Management
Limited or Societe Generale Asset Management on behalf of clients who terminate
the mandate for holding such Mowlem Shares with Schroder Investment Management
Limited or, as the case may be, Societe Generale Asset Management.  Under the
irrevocable undertaking referred to above given by Aberforth Partners LLP,
Aberforth Partners LLP retains the right to accept a higher competing offer made
for Mowlem Shares which represents, in its reasonable opinion, an improvement of
not less than 10 per cent. in the value offered by Carillion.


4.       Recommendation



The Mowlem Directors, who have been so advised by Rothschild, consider the
revised terms of the proposed acquisition to be fair and reasonable. In
providing its advice to the Mowlem Directors, Rothschild has taken into account
the commercial assessments of the Mowlem Directors.



In coming to this recommendation, the Mowlem Directors have taken account of
Balfour Beatty plc's approach but the Mowlem Directors have decided that, in
view of the value, certainty and quality of Carillion's offer, they should
recommend Carillion's offer.



Accordingly, the Board of Mowlem will unanimously recommend Mowlem Shareholders
vote in favour of the resolutions to be proposed at the Scheme Meeting and the
Mowlem Extraordinary General Meeting, as they have irrevocably undertaken to do
in respect of their own respective beneficial holdings, amounting in aggregate
to 46,193 Mowlem Shares, representing approximately 0.033 per cent. of Mowlem's
issued share capital.


5.       Further Details of the Acquisition and Terms of the Mix and Match Facility



Based on the Closing Price of 300.5 pence per Carillion Share on 14 December
2005, being the last Business Day before this announcement, the Acquisition
values each Mowlem Share at approximately 220 pence and the existing issued
share capital of Mowlem at approximately £313 million.  These revised terms
represent a premium of approximately:


*      27 per cent. to the Closing Price of 173 pence per Mowlem Share on 28 October 2005, the last
       Business Day prior to the day of the announcement made by Mowlem that it had received an
       approach; and

*      41 per cent. to the average closing price of approximately 156 pence per Mowlem Share over the
       last three months prior to and including 28 October 2005, being the last Business Day before the
       day of the announcement made by Mowlem that it had received an approach.



Assuming a maximum number of 65.4 million New Carillion Shares will be issued
pursuant to the revised terms of the Acquisition, Mowlem Shareholders will hold
Carillion Shares representing approximately 23.3 per cent. of the Enlarged
Group.  In addition, Mowlem Shareholders will have received cash consideration,
in aggregate, of approximately £116 million.



As fractions of New Carillion Shares will not be allotted or issued to persons
pursuant to the Scheme, fractional entitlements to New Carillion Shares will be
aggregated and sold in the market and the net proceeds of sale will be
distributed pro rata to persons entitled thereto.



It is currently expected that the following will happen in the order set out
below immediately prior to the Scheme becoming Effective:


*      The Scheme Shares will be subdivided and converted into two further new classes of shares in the
       capital of Mowlem; and

*      further Scheme Shares will be issued to participants in the Mowlem Share Schemes who have
       exercised their options and awards under such schemes (see paragraph 17),



and upon the Scheme becoming Effective:


*      the Scheme Shares will be cancelled and in their place new ordinary shares of 25 pence each in
       the capital of Mowlem will be issued to Carillion (or its nominee(s)), whereupon Mowlem will
       become a wholly-owned subsidiary of Carillion; and

*      the cash and/or New Carillion Shares due to each Mowlem Shareholder pursuant to the Scheme will
       be paid or issued to such Mowlem Shareholder within 14 days of the Effective Date.



Mowlem Shareholders (other than certain Overseas Persons) will be entitled to
elect, subject to availability, to vary the proportions in which they receive
New Carillion Shares and cash in respect of their holdings of Mowlem Shares.
However, the total number of New Carillion Shares to be issued and the maximum
aggregate amount of cash to be paid under the Scheme will not be varied as a
result of elections under the Mix and Match Facility.



Accordingly, elections made by Mowlem Shareholders under the Mix and Match
Facility will only be satisfied to the extent that other Mowlem Shareholders
make offsetting elections.  Satisfaction of elections under the Mix and Match
Facility will be effected on the basis of 300.5 pence in cash (being the Closing
Price of a Carillion Share on 14 December 2005, the last practicable date before
this announcement) for each New Carillion Share.  To the extent that elections
cannot be satisfied in full, they will be scaled down on a pro rata basis.  As a
result, Mowlem Shareholders who make an election under the Mix and Match
Facility will not know the exact number of New Carillion Shares or the amount of
cash they will receive until settlement of the consideration due to them in
respect of the Acquisition.



The Mix and Match Facility is conditional upon the Acquisition becoming
Effective and further details on the Mix and Match Facility will be included in
the Scheme Document.


6.       Background to, and reasons for, the Acquisition



Carillion continues to believe that the Acquisition will create significant
value for its shareholders by bringing together two companies with an excellent
strategic fit and complementary skills and market strengths, particularly in
support services and private finance.  The Acquisition will create one of the
largest support services and construction companies in the UK, with a combined
turnover  of approximately £4.1 billion.



The Acquisition is consistent with Carillion's strategic objective of seeking to
deliver sustainable, profitable growth through:


*      growing support services organically and by acquisition;

*      creating value through investments in Public Private Partnership ('PPP') projects;

*      maintaining a strong and selective construction capability focused on higher added value
       contracts for longer term customers; and

*      developing and marketing integrated solutions tailored to the needs of customers, including
       project finance, design, construction, maintenance and lifetime asset management.



The Acquisition of Mowlem is an important step change in Carillion's development
and Carillion is confident that the Acquisition will produce attractive returns
for its shareholders.  Through careful integration and management, Carillion is
targeting increases in Mowlem's margins in Support Services and Construction
with a view over time of bringing them towards those of Carillion.  In addition,
the Acquisition is expected to generate significant cost synergies (see note 4,
Appendix II).  Furthermore, Carillion believes the Acquisition will materially
enhance earnings in 2007, the first full year after completion of the
Acquisition (see note 5, Appendix II).



Support Services



The Enlarged Group will benefit from significantly enhanced capabilities and
positions in a number of support services markets with strong growth dynamics.
With annual turnover of approximately £1.5 billion, it will also be one of the
largest suppliers of support services in the UK.



The Enlarged Group will have a broader range of skills and capabilities,
strengthening its integrated services offering across the UK facilities
management ('FM') market.  The Acquisition will combine Carillion's strengths in
the telecommunications, health and defence sectors with Mowlem's strengths in
the financial services and retail sectors.  The stronger integrated services
offering of the Enlarged Group will make it better equipped to enter and succeed
in new sectors.  Mechanical and electrical engineering ('M&E') maintenance is a
major element of an integrated FM service and combining the M&E maintenance
capabilities of Carillion and Mowlem will create a market leading M&E
maintenance business in the UK.



In the UK rail infrastructure services market, Carillion's position as a leading
supplier of integrated solutions for projects to upgrade and renew the rail
network will be strengthened by the addition of Mowlem's specialist rail
services skills.



Investments



Carillion's position as a market leader in PPP projects will be significantly
enhanced by the Acquisition as Mowlem also has a major presence in this sector.
Carillion has a portfolio of 18 financially closed projects, in which it has
invested equity of approximately £29 million and commitments to invest a further
£20 million.  Mowlem has a portfolio of 10 financially closed equity
participation PPP projects in which it has either invested or has existing
commitments to invest equity of approximately £51 million at par value.  The
total equity invested or committed to date for the combined portfolios of
Carillion and Mowlem is expected to be approximately £100 million as at 6
December 2005.



The Enlarged Group will have a strong pipeline of new PPP projects with the
potential to create significant additional value.  Mowlem is currently the
preferred bidder for 3 equity participation projects for the Ministry of
Defence, in which it expects to invest total equity of approximately £46.5
million at par value, including £30 million in the Allenby Connaught project.
Beyond that, the Enlarged Group is shortlisted for a further 10 PPP projects
with a potential equity requirement of up to £73.5 million.



In addition to creating a larger and more diversified portfolio of PPP equity
investments, the ability of the Enlarged Group to bid for and win new PPP
projects will be significantly improved through the increased availability of
specialist private finance, support services and construction skills and
resources to the Enlarged Group, which is currently the main constraint to
growth.



Construction Services



The construction services activities of Carillion and Mowlem will have a
combined turnover of approximately £2.5 billion and together will be a leading
building business in the UK market.  The business will be managed in line with
Carillion's selective approach to construction.



In the UK commercial building sector, Carillion is primarily focused on larger
building projects with a particularly strong presence in the education, retail,
high-rise urban residential, offices and mixed-use development sectors.  The
addition of Mowlem's skills and resources, particularly its strengths in the
education and defence sectors and also in smaller-scale building projects, will
create a leading UK building business.



In UK civil engineering, Carillion's activities are tightly focused on projects
procured under the Government's Early Contractor Involvement Programme.
Carillion believes that Mowlem's capabilities in infrastructure will complement
these activities.



International



Carillion has well-established and successful international regional businesses
in the Middle East, Canada and the Caribbean.  While the majority of revenues
from these businesses are currently generated from construction services, an
increasing proportion is being generated from support services and PPP
investments.  Carillion's strategy is to maintain an international presence only
where it can develop support services and PPP investments alongside strong and
selective construction businesses.  The Enlarged Group will adopt the same
strategy for Mowlem's businesses in Australia and the US.



Synergies



In addition to the expected benefits of the Acquisition referred to above, there
is the potential to generate significant synergy benefits.



Carillion believes it can achieve an annual running rate of operating cost
savings in the Enlarged Group of approximately £10 million by the end of 2006,
which will broadly equal the one-off costs of delivering those savings, and of
£15 million per year by the end of 2007 (see note 4, Appendix II).  Cost savings
are expected to arise broadly equally from the restructuring of head office and
regional properties, from improved supply chain management and from savings in
support functions, insurances, property and other costs.  Within its existing
business, Carillion has already demonstrated that it can make substantial
savings in these same areas.



Carillion also believes that the Acquisition will create a number of
cross-selling opportunities within the Enlarged Group and generate revenue
synergies in areas such as rail, FM, M&E maintenance, vehicle fleet management
and the recruitment and supply of operational personnel.


7.       Financial Effects of the Acquisition



The Acquisition is expected to be materially earnings enhancing (see note 5,
Appendix II) for Carillion in 2007, the first full year following completion of
the Acquisition.  Given the benefits of the Acquisition outlined above,
Carillion is confident of the financial and trading prospects of the Enlarged
Group.



As at 31 October 2005, Carillion had net cash of £76 million and Mowlem had net
debt of £76 million (see note 6, Appendix II) which Carillion will refinance on
completion of the Acquisition.  Carillion has arranged new debt financing
facilities with The Royal Bank of Scotland to finance the Acquisition and the
working capital needs of the Enlarged Group.  On a proforma basis for 2006, it
is expected that the Enlarged Group will have average net debt of approximately
£200 million and a peak net debt position of approximately £250 million in that
year.  As a result of actions to be taken by Carillion management, including
disposals, Carillion expects to achieve a substantial reduction in net debt
within the next 24 months.



It is expected that, consistent with Carillion's existing approach, Carillion
will adjust the balance sheet of Mowlem by approximately £120 million, of which
approximately £45 million relates to writedowns on a small number of contracts
and the remainder to changes in the carrying values of goodwill and the deferred
tax asset.  Carillion will subsequently disclose any material releases from
these provisions.


8.       Background to and reasons for recommending the Acquisition



Mowlem has been through a period of significant change in 2005 with the
appointment of a new Chairman, Chief Executive and Finance Director during the
year. There has been a great deal of internal activity with the reorganisation
of the construction services division in April and the recent closure of a
number of unprofitable operations. Improved risk management processes have been
implemented and, following a comprehensive review of the contracts portfolio,
new more prudent rules on claims valuation and profit recognition have been
introduced. These changes have provided Mowlem with a strong foundation to
further develop the business in future, but the Mowlem Directors believe the
combination of the two groups has attractive strategic advantages for both
companies and offers the opportunity to accelerate the delivery of value to
Mowlem Shareholders.



The Mowlem Directors therefore continue to believe that the Acquisition is in
the best interests of Mowlem Shareholders and, therefore, will unanimously
recommend that they approve the Acquisition on its revised terms.  The revised
terms of the Acquisition being offered by Carillion provide Mowlem Shareholders
with a significant proportion of their current investment in cash while the
enhanced share element gives them the ability to benefit significantly from a
recovery in Mowlem's business and the value to be created from the combination
of Carillion and Mowlem, and its future growth.


9.       Information on Carillion



Since its demerger from Tarmac in 1999, Carillion has been successfully
transformed from a predominantly construction business to become a leading
support services and construction company both in the UK and in its chosen
international regions.  The change in business mix and introduction of rigorous
new management procedures has significantly improved the risk profile of its
activities and the predictability of its earnings.



Carillion has three business segments for reporting purposes:


*        Support Services, which includes rail and road infrastructure services, facilities management,
         mechanical and electrical engineering maintenance and other support services;

*        Investments, in which segment Carillion reports the returns on its equity investments in PPP
         projects; and

*        Construction Services, which includes all UK building and civil engineering activities together
         with those of its international regional businesses.



Carillion's current portfolio comprises many high-profile successful contracts
in the UK and overseas, including:


*        in the UK: FM contracts for BT, Telewest Broadband, ten NHS hospitals and various other
         government and commercial properties; maintenance of the M11, M25 and M40; the upgrading of
         large sections of the UK rail network; and the construction of the M6 Toll motorway and the new
         Government Communications Headquarters in Cheltenham; and

*        through its international operations: in Canada, two of the country's first PPP hospitals and
         the maintenance of a substantial proportion of the provincial road network in Ontario; in the
         Middle East, it is building large parts of the multi-billion pound Dubai Festival City
         development and growing a substantial FM business.



As at 14 December 2005 (the last Business Day before the date of this
announcement), Carillion had a market capitalisation of approximately £646
million.  In the year to 31 December 2004 as reported under UK GAAP, Carillion
generated revenues (including its share of joint ventures) of £2.0 billion,
profit on ordinary activities before tax, goodwill amortisation and exceptional
items of £51 million, and as at 31 December 2004 had net assets of £187 million.
  In the six months to 30 June 2005 as reported under IFRS, Carillion generated
revenues (including its share of joint ventures) of £1,011 million, profit on
ordinary activities before tax, amortisation and exceptional items of £18
million, and as at 30 June 2005 had net assets of £114 million.  At that date,
the Carillion Directors valued Carillion's portfolio of PPP investments at £84
million.


10.      Current Trading



Carillion will be announcing its normal pre-close trading update in early
January 2006 but in the meantime can confirm that trading continues to be in
line with its expectations.


11.      Information on Mowlem



Mowlem is an international provider of construction and support services to
public and private sector customers operating across a comprehensive range of
market sectors.  Mowlem offers a wide range of construction and support
services, from major building and infrastructure projects through to smaller
building and civil engineering works; and from total facilities management
through to direct delivery of mechanical and electrical (M&E), cleaning and
security services.



Recent years have seen a radical change in the nature and shape of the Mowlem
business, successfully evolving from being a pure construction contractor into
one of the UK's leading construction and support services group, able to deliver
a full range of capabilities to the built environment.



Mowlem has four business segments for reporting purposes:


*        Construction Services: this includes Building, which provides a comprehensive national building
         service to the public and private sectors, from larger building projects through to smaller
         building works, delivered through a network of regional offices covering the UK; Infrastructure,
         a multi-discipline business spanning the full range of civil engineering and related
         disciplines, offering total infrastructure services capability to clients, including the rail,
         highways, water and utilities sectors; and Engineering, comprising specialist businesses from M&
         E, multi-discipline design, construction and maintenance services across all commercial and
         industrial applications;

*        Support Services: this includes Mowlem Asset Services, the strategic customer facilities and
         asset management business, the Mowlem Pall Mall cleaning services and security business and the
         Mowlem Environmental Sciences Group;

*        Projects: this integrates Mowlem's PPP, public sector services and major project building
         activities into one business.  Mowlem has a broad portfolio with a number of investment
         projects in the health, education, defence, judicial and medical sectors.  The largest project
         in this portfolio (a joint venture with Kellogg, Brown and Root) is the Allenby Connaught
         project for the Ministry of Defence, which is at preferred bidder stage and involves £7 billion
         of new build, refurbishment and facilities management services over 35 years; and

*        International: an engineering and construction business covering the building, civil engineering
         and rail sectors through the Group's Australian subsidiary, Barclay Mowlem, and its US building
         business, Charter Builders.



For the year ended 31 December 2004 as reported under UK GAAP, Mowlem generated
turnover (including its share of joint ventures) of £2.0 billion, profit on
ordinary activities before tax, goodwill amortisation and operating exceptional
items of £0.3 million, and as at 31 December 2004 had net assets of £187
million.  In six months to 30 June 2005 as reported under IFRS, Mowlem generated
turnover (including its share of joint ventures) of £1.1 billion, profit on
ordinary activities before tax, amortisation and exceptional items of £4.1
million and at 30 June 2005 had net assets of £54 million.  At September 2005
and at a discount rate of 10 per cent. the Mowlem Directors valued Mowlem's
portfolio of PPP investments and preferred bidder opportunities at £73 million.


12.      Implementation Deed and Inducement Fee Arrangements



Carillion and Mowlem have entered into the Implementation Deed which governs
their relationship during the period until the Acquisition becomes Effective or
lapses.  Among other things, the parties have agreed to co-operate with regard
to the process of implementing the Acquisition.  The Implementation Deed will
terminate (without prejudice to any obligations on Mowlem to pay the break fee
(see below)) in certain circumstances, including if the Acquisition lapses or if
the Scheme or the Acquisition is not approved at the Scheme Meeting or the
Mowlem Extraordinary General Meeting or the Carillion Extraordinary General
Meeting (as appropriate).



Carillion and Mowlem have agreed a break fee letter under which Mowlem has
agreed to pay Carillion a break fee (inclusive of value added tax) equal to one
per cent. of the value of Mowlem calculated by reference to the original terms
of the Acquisition as at 7 December 2005 if (i) a third party transaction is
announced before the Acquisition lapses or is withdrawn; and thereafter (ii)
such third party transaction, or any other third party transaction announced
after the Acquisition is formally announced, becomes or is declared
unconditional in all respects or is completed.


13.      The New Carillion Shares



The New Carillion Shares to be issued pursuant to the revised terms of the
Acquisition will be ordinary shares of 50 pence each in the capital of
Carillion.  The New Carillion Shares will be issued in registered form, will be
capable of being held in both certificated and uncertificated form, will be
issued credited as fully paid and will rank pari passu in all respects with the
existing Carillion Shares.  The New Carillion Shares will carry the right to
Carillion's final dividend in respect of the year to 31 December 2005.


14.      Dividend Policy



Following completion of the Acquisition, Carillion intends to maintain its
existing dividend policy.  In the absence of unforeseen circumstances, the Board
of Carillion expects to propose a final dividend of not less that 5 pence per
Carillion Share in respect of the year ending 31 December 2005.


15.      Directors, Management, Employees of Mowlem



Carillion attaches great importance to the skills and experience of the existing
management and employees of Mowlem and believes that opportunities for them will
be enhanced in the event that the Acquisition becomes Effective.



On completion of the Acquisition, Carillion intends to invite Simon Vivian, the
Chief Executive of Mowlem, to join its Board as an executive director.



The Board of Carillion has also given assurances to the Mowlem Directors that,
following the Acquisition becoming Effective, the existing contractual
employment rights of all employees of the Mowlem Group will be fully
safeguarded.


16.      Disclosure of Interests in Mowlem



Save for the arrangements with Mowlem Shareholders in relation to irrevocable
undertakings summarised in paragraph 3 above, neither Carillion nor, so far as
the Carillion Directors are aware, any person deemed to be acting in concert
with Carillion owns or controls any Mowlem Shares or any securities convertible
or exchangeable into Mowlem Shares or options (including traded options) in
respect of, or derivatives referenced to, any such shares ('Relevant Mowlem
Securities') nor does any such person have any arrangement in relation to
Relevant Mowlem Securities.  For these purposes, 'arrangement' includes any
indemnity or option arrangement, any agreement or understanding, formal or
informal, of whatever nature, relating to Relevant Mowlem Securities which may
be an inducement to deal or refrain from dealing in such Relevant Mowlem
Securities.


17.      Mowlem Share Schemes



The Acquisition will, as described in paragraph 5 above, extend to all Mowlem
Shares issued upon the exercise of the options under the Mowlem Share Schemes
before the Scheme becomes Effective.  Appropriate proposals will be made in due
course to participants in the Mowlem Share Schemes.


18.      Pensions



Mowlem will continue to make regular contributions to its two main pension
schemes to fund the cost of ongoing accrual of benefits. In addition, Mowlem
intends to make further contributions of £13 million per annum to these schemes
from 2006 onwards with the aim of eliminating the schemes' deficits on a funding
basis by 31 December 2016.  Carillion will discuss with the trustees of its
pension scheme additional contributions (over and above the regular
contributions) to the schemes in order to address the scheme deficits.  While
the cash amounts of any incremental payments may be significant, they are not
expected to have a material impact on reported profits.


19.      Settlement, Listing and Dealing of New Carillion Shares



Applications will be made to the UK Listing Authority and to the London Stock
Exchange for the New Carillion Shares to be issued in connection with the
Acquisition to be admitted to the Official List and to trading on the London
Stock Exchange's main market for listed securities.  It is expected that
admission of the New Carillion Shares to the Official List and to trading on the
London Stock Exchange's main market for listed securities will become effective,
and that dealings for normal settlement in the New Carillion Shares will
commence, on the date on which the Scheme become Effective.



The existing Carillion Shares are already admitted to CREST.  It is expected
that all of the New Carillion Shares, when issued and fully paid, will be
capable of being held and transferred by means of CREST.  It is expected that
the New Carillion Shares will trade under ISIN GB0007365546.



Further details on listing, dealing and settlement will be included in the
formal Scheme Document.


20.      Implementation of the Scheme and cancellation of listing



It is intended that the Acquisition will be effected by means of a scheme of
arrangement between Mowlem and the Mowlem Shareholders under section 425 of the
Companies Act.  The procedure involves an application by Mowlem to the Court to
sanction the Scheme and confirm the cancellation of all the existing Mowlem
Shares (other than any Mowlem Shares already beneficially held by the Carillion
Group (if any)).  In consideration for the cancellation of their Mowlem Shares,
Mowlem Shareholders, who are Scheme Shareholders, will receive cash and New
Carillion Shares as outlined in paragraph 2 above.  Following implementation of
the Scheme, Mowlem will become a wholly-owned subsidiary of Carillion.



The Scheme will be subject, among other things, to the Conditions set out in
Appendix I to this announcement, including approval by Mowlem Shareholders by
the passing of a resolution at a meeting of the Mowlem Shareholders convened by
the order of the Court pursuant to section 425 of the Companies Act to consider
and, if thought fit, approve the Scheme with or without any modification thereof
(and any adjournment thereof).  This resolution must be approved by a majority
in number of the holders of Mowlem Shares (other than members of the Carillion
Group, if relevant) present and voting, either in person or by proxy, at the
Scheme Meeting, representing not less than three-fourths in value of the Mowlem
Shares held by such holders.  The Scheme must also be sanctioned by the Court
and the associated Capital Reduction must be confirmed by the Court, in each
case at the relevant Court Hearings.



In addition, the implementation of the Scheme will require separate approval by
the passing of a special resolution at the Mowlem Extraordinary General Meeting,
inter alia, to:



*        approve the Scheme and to authorise the Mowlem Directors to take such action as they consider
         necessary or appropriate to effect the Scheme;

*        reclassify and subsequently cancel any existing Mowlem Shares (other than Mowlem Shares already
         held by Carillion (if any)) and approve the issue of new shares of 25 pence each in Mowlem to
         Carillion (and/or its nominee(s)) in accordance with the Scheme; and

*        amend the Mowlem articles of association to ensure that the Mowlem Shares issued under the
         Mowlem Share Schemes will be subject to the Scheme or, if issued following the Scheme Record
         Time, will be automatically transferred to Carillion on the same terms as under the Scheme.




The Mowlem Extraordinary General Meeting will be held directly after the Scheme
Meeting.



If the Scheme becomes Effective, it will be binding on all Scheme Shareholders
irrespective of whether or not they attend or vote in favour of the Scheme at
the Scheme Meeting or in favour of the special resolution to be proposed at the
Mowlem Extraordinary General Meeting.  Prior to the Scheme becoming Effective,
Carillion intends to apply to the Financial Services Authority for the listing
of Mowlem Shares to be cancelled and to the London Stock Exchange for the Mowlem
Shares to cease to be admitted to trading on the London Stock Exchange's market
for listed securities.  This will take effect on the Effective Date.


21.      Carillion Shareholder Approval



The Acquisition constitutes a Class 1 transaction (as defined in the Listing
Rules of the UKLA) for Carillion. Accordingly, Carillion will be required to
seek the approval of its shareholders for the Acquisition at the Carillion
Extraordinary General Meeting. Carillion will prepare and send to its
shareholders, as soon as is reasonably practicable, an explanatory circular
summarising the background to and reasons for the Acquisition (which will
include a notice convening the Carillion Extraordinary General Meeting).  The
Acquisition will be conditional on, among other things, the requisite resolution
being passed by the Carillion Shareholders at the Carillion Extraordinary
General Meeting.


22.      Overseas Shareholders



The availability of New Carillion Shares under the terms of the Acquisition to
persons not resident in the United Kingdom may be affected by the laws of the
relevant jurisdiction.  Such persons should inform themselves about and observe
any applicable requirements.  Further details in relation to Overseas
Shareholders will be contained in the Scheme Document.


23.      General



The formal documentation setting out the details of the Acquisition, including
the Scheme Document setting out the procedures to be followed to approve the
Scheme, with the forms of proxy for use in connection with the Scheme Meeting
and the Mowlem Extraordinary General Meeting and the forms of election under
which Mowlem Shareholders can elect for varying proportions of cash and New
Carillion Shares under the Mix and Match Facility, together with the Information
Memorandum relating to Carillion and the New Carillion Shares, will be posted to
Mowlem Shareholders and, for information only, to participants in the Mowlem
Share Schemes (other than to persons with addresses in Restricted Territories)
as soon as is reasonably practicable and, in any event within 28 days of the
date of this announcement (or such later date as Carillion and Mowlem may, with
the consent of the Panel, agree).



The Scheme Document will include full details of the Scheme, together with
notices of the Court Meeting and the Mowlem Extraordinary General Meeting and
the expected timetable, and will specify the necessary action to be taken by the
Scheme Shareholders.



The sources and bases of information set out in this announcement are contained

announcement are contained in Appendix III.

Dealing Restrictions



Under the provisions of Rule 8.3 of the City Code on Takeovers and Mergers (the
'Code'), if any person is, or becomes, 'interested' (directly or indirectly) in
1% or more of any class of 'relevant securities' of Carillion or of Mowlem, all
'dealings' in any 'relevant securities' of that company (including by means of
an option in respect of, or a derivative referenced to, any such 'relevant
securities') must be publicly disclosed by no later than 3.30pm (London time) on
the London business day following the date of the relevant transaction.  This
requirement will continue until the date on which the offer becomes, or is
declared, unconditional as to acceptances, lapses or is otherwise withdrawn or
on which the 'offer period' otherwise ends.  If two or more persons act together
pursuant to an agreement or understanding, whether formal or informal, to
acquire an 'interest' in 'relevant securities' of Carillion or Mowlem, they will
be deemed to be a single person for the purpose of Rule 8.3.



Under the provisions of Rule 8.1 of the Code, all 'dealings' in 'relevant
securities' of Carillion or Mowlem by Carillion or Mowlem, or by any of their
respective 'associates' must be disclosed by no later than 12.00 noon (London
time) on the London business day following the date of the relevant transaction.



A disclosure table, giving details of the companies in whose 'relevant
securities' 'dealings' should be disclosed, and the number of such securities in
issue, can be found on the Panel's website at www.thetakeoverpanel.org.uk.



'Interests in securities' arise, in summary, when a person has long economic
exposure, whether conditional or absolute, to changes in the price of
securities.  In particular, a person will be treated as having an 'interest' by
virtue of the 'ownership' or control of securities, or by virtue of any option
in respect of, or derivative referenced to, securities.



Terms in quotation marks are defined in the Code, which can also be found on the
Panel's website.  If you are in any doubt as to whether or not you are required
to disclose a 'dealing' under Rule 8, you should consult the Panel.

securities laws of any state, district or jurisdiction of the United States and
may not be offered, sold or delivered, directly or indirectly, in the United
States, other than pursuant to an exemption from any such registration
requirements.  Carillion does not intend to register any such takeover offer or
any part thereof in the United States or to conduct a public offering of the New
Carillion Shares in the United States.



This announcement is not an offer of securities for sale in the US and the New
Carillion Shares have not been, and will not be, registered under the US
Securities Act of 1933 (the 'Securities Act') or under the securities laws of
any state, district or other jurisdiction of the US, Australia, Canada or Japan
and no regulatory clearance in respect of the New Carillion Shares has been, or
will be, applied for in any jurisdiction other than the UK.  It is expected that
the New Carillion Shares will be issued in reliance upon the exemption from the
registration requirements of the Securities Act provided by Section 3(a) (10)
thereof.  Under applicable US securities laws, Mowlem Shareholders who are or
will be deemed to be 'affiliates' of Mowlem or Carillion prior to, or of
Carillion after, the Effective Date will be subject to certain transfer
restrictions relating to the New Carillion Shares received in connection with
the Acquisition.



Whether or not a Mowlem Shareholder's Mowlem Shares are voted at the Scheme
Meeting or the Mowlem Extraordinary General Meeting, if the Scheme becomes
Effective, those Mowlem Shares will be acquired pursuant to the Scheme and
Mowlem Shareholders will, subject to the Mix and Match Facility, receive a
payment of 82 pence in cash and 0.46 New Carillion Shares for every Mowlem
Share.



Mowlem will prepare the Scheme Document to be distributed to Mowlem
Shareholders.  Carillion and Mowlem urge Mowlem Shareholders to read the Scheme
Document when it becomes available because it will contain important information
relating to the Acquisition.  Mowlem Shareholders may obtain a further free copy
of the Scheme Document, when it becomes available, from Macfarlanes.



This announcement contains statements about Carillion and Mowlem that are or may
be forward looking statements. All statements other than statements of
historical facts included in this announcement may be forward looking
statements.  Without limitation, any statements preceded or followed by or that
include the words 'targets', 'plans' 'believes', 'expects', 'aims',' intends', '

significantly affect expected results and are based on certain key assumptions.
Many factors could cause actual results to differ materially from those

uncertainties and risks, readers are cautioned not to place undue reliance on
such forward looking statements, which speak only as of the date hereof.

                             normal in the context of the business concerned, to an extent which is
                             or would be reasonably likely to be material in the context of the
                             wider Mowlem Group as a whole or wider Carillion Group as a whole;

                             respect to or announced any intention to, or to propose to, effect any

                    the term 'Mowlem Group' shall mean Mowlem and its wholly-owned subsidiaries;

          g)        since 31 December 2004 and save as disclosed in the accounts for the year then
                    ended and save as (i) disclosed in the interim report of Mowlem for the six
                    months ended 30 June 2005 or (ii) publicly announced in accordance with the
                    Listing Rules by Mowlem prior to 7 December 2005:

                    (i)      no material adverse change or deterioration having occurred in the

                    Carillion not having discovered:

                    i)       that any financial, business or other information concerning the wider

                             time by or on behalf of any member of the wider Mowlem Group is
                             materially misleading, contains a material misrepresentation of fact or
                             omits to state a fact necessary to make that information not materially
                             misleading; or

                    ii)      that any member of the wider Mowlem Group is subject to any liability
                             (contingent or otherwise which is material in the context of the Mowlem
                             Group as a whole) which is not disclosed in the annual report and
                             accounts of Mowlem for the year ended 31 December 2004;

          i)        Carillion not having discovered that:

                    i)       any past or present member of the wider Mowlem Group has failed to
                             comply with any and/or all applicable legislation or regulation, of any
                             jurisdiction with regard to the disposal, spillage, release, discharge,
                             leak or emission of any waste or hazardous substance or any substance
                             likely to impair the environment or harm human health or animal health
                             or otherwise relating to environmental matters, or that there has
                             otherwise been any such disposal, spillage, release, discharge, leak or
                             emission (whether or not the same constituted a non-compliance by any
                             person with any such legislation or regulations, and wherever the same
                             may have taken place) any of which disposal, spillage, release,
                             discharge, leak or emission would be likely to give rise to any
                             liability (actual or contingent) on the part of any member of the wider
                             Mowlem Group and which is material in the context of the wider Mowlem
                             Group as a whole; or

                    ii)      there is, or is likely to be, for that or any other reason whatsoever,
                             any liability (actual or contingent) of any past or present member of
                             the wider Mowlem Group to make good, repair, reinstate or clean up any
                             property or any controlled waters now or previously owned, occupied,
                             operated or made use of or controlled by any such past or present
                             member of the wider Mowlem Group, under any environmental legislation,
                             regulation, notice, circular or order of any government, governmental,
                             quasi-governmental, state or local government, supranational, statutory
                             or other regulatory body, agency, court, association or any other
                             person or body in any jurisdiction and which is material in the context
                             of the wider Mowlem Group as a whole.

4         For the purposes of these conditions the 'wider Mowlem Group' means Mowlem and its
          subsidiary undertakings, associated undertakings and any other undertaking in which Mowlem
          and/or such undertakings (aggregating their interests) have a significant interest and the
          'wider Carillion Group' means Carillion and its subsidiary undertakings, associated
          undertakings and any other undertaking in which Carillion and/or such undertakings
          (aggregating their interests) have a significant interest and for these purposes '
          subsidiary undertaking', 'associated undertaking' and 'undertaking' have the meanings
          given by the Companies Act 1985, other than paragraph 20(1)(b) of Schedule 4A to that Act
          which shall be excluded for this purpose, and 'significant interest' means a direct or
          indirect interest in ten per cent. or more of the equity share capital (as defined in that
          Act), provided that investments in the equity of any entity for the purposes of any PPP
          project shall be excluded from the 'wider Mowlem Group'.

5         Carillion reserves the right to waive, in whole or in part, all or any of the above
          conditions, except conditions 1, 2 and 3(b).

6         If Carillion is required by the Panel to make an offer for Mowlem Shares under the
          provisions of Rule 9 of the Code, Carillion may make such alterations to any of the above
          conditions as are necessary to comply with the provisions of that Rule.

7         Carillion reserves the right to elect to implement the Acquisition by way of a takeover
          offer under section 428 of the Companies Act.  In such event, the Acquisition will be
          implemented on the same terms (subject to appropriate amendments including (without
          limitation) an acceptance condition set at 90 per cent. of the shares to which the
          Acquisition relates), so far as applicable, as those which would apply to the
          implementation of the Acquisition by means of the Scheme.

8         The Acquisition will not proceed if, after the date of this announcement and before the
          Mowlem Extraordinary General Meeting, the Acquisition is referred to the Competition
          Commission.

9         This Acquisition will be governed by English law and be subject to the jurisdiction of the
          English courts, to the conditions set out in this announcement and in the formal Scheme
          Document and related Form of Election.


PART B

Certain further terms of the Acquisition



1        Fractions of New Carillion Shares will not be allotted or issued pursuant to the Scheme.
         Fractional entitlements to New Carillion Shares will be aggregated and sold in the market and
         the net proceeds of sale distributed pro rata to persons entitled thereto.

2        The New Carillion Shares to be issued pursuant to the Scheme have not been and will not be
         registered under the United States Securities Act of 1933 (as amended) nor under any of the
         relevant securities laws of Canada, Japan or Australia.  Accordingly, the New Carillion
         Shares may not be offered, sold or delivered, directly or indirectly, in the United States,
         Canada, Japan or Australia nor to any United States person, except pursuant to exemptions
         from applicable requirements of any such jurisdiction.

3        The New Carillion Shares will be issued credited as fully paid and will rank pari passu in
         all respects with the existing Carillion Shares.  Applications have been made to the UK
         Listing Authority for the New Carillion Shares to be admitted to the Official List and to the
         London Stock Exchange for the New Carillion Shares to be admitted to trading.


                                  APPENDIX II

                               SOURCES AND BASES


1         Unless otherwise stated:

          *        financial information relating to Carillion has been extracted or provided (without
                   material adjustment) from the audited annual report and accounts for Carillion for
                   the year ended 31 December 2004 reported under UK GAAP and the unaudited interim
                   report and accounts for the six months ended 30 June 2005 reported under IFRS

          *        financial information relating to Mowlem has been extracted or provided (without
                   material adjustment) from the audited annual report and accounts for Mowlem for the
                   year ended 31 December 2004 reported under UK GAAP and the unaudited interim report
                   and accounts for the six months ended 30 June 2005 reported under IFRS

2         The terms of the Acquisition value each Mowlem Share at 220 pence.  The Acquisition price is
          based on a share price of 300.5 pence per Carillion Share (the Closing Price on 14 December
          2005, the last practicable date prior to this announcement) and 0.46 Carillion Shares to be
          issued for each Mowlem Share representing 138 pence in Carillion Shares, plus 82 pence in
          cash

3         As at the close of business on 14 December 2005, Carillion had in issue 214,903,021 ordinary
          shares of 50 pence each; and Mowlem had in issue 142,086,776 ordinary shares of 25 pence
          each

4         The expected operational cost savings have been calculated on the basis of the existing cost
          and operating structures of the Carillion and Mowlem Groups.  These statements of estimated
          cost savings and one-off costs for achieving them relate to future actions and circumstances
          which, by their nature, involve risks, uncertainties and other factors.  Because of this,
          the cost savings referred to may not be achieved, or those achieved could be materially
          different from those estimated.  This statement is not intended to be a profit forecast and
          should not be interpreted to mean that the earnings per share in 2006, 2007 or in any
          subsequent financial period, would necessarily match or be greater than those for the
          relevant preceding financial period

5         The statements that the Acquisition is expected to be materially earnings enhancing for
          Carillion in 2007 (the first full year following completion of the Acquisition) relate to
          future actions and circumstances, which, by their nature, involve risks, uncertainties and
          other factors. These statements do not constitute a profit forecast and should not be
          interpreted to mean that earnings for that year or any subsequent financial period would
          necessarily match or be greater than those for any preceding financial period.  Earnings in
          this context represent net after tax earnings before the amortisation of intangible assets
          and non-operating items

6         Net debt / cash in this context represents total debt, excluding finance leases, less total
          cash balances (including cash in joint ventures)
