                                             Posting of Scheme Document and Trading Update

On 15 May 2007, Hanson and  HeidelbergCement  announced that they had reached agreement on the terms of the recommended  acquisition of
the entire issued and to be issued share capital of Hanson at a price of 1100 pence in cash for each Hanson Share.

It is intended that the  Acquisition  will be implemented by way of a Court approved  procedure  known as a scheme of arrangement  (the
"Scheme")  under  section 425 of the Companies Act 1985 (the "Act").  Hanson now  announces  that the document (the "Scheme  Document")
containing,  inter alia, the terms of the Scheme, an explanatory  statement (in compliance with section 426 of the Act), notices of the
required meetings,  a timetable of principal events,  and details of the action to be taken by Hanson  Shareholders was today posted to
all Hanson Shareholders, ADS Holders and CDI Holders.

As described in the Scheme Document,  the Scheme will require the approval of Hanson  Shareholders at the Court Meeting and the passing
of a special  resolution at an Extraordinary  General Meeting of Hanson.  The Court Meeting and the Extraordinary  General Meeting will
both be held at The Royal Aeronautical Society, 4 Hamilton Place,  Mayfair,  London W1J 7BQ on Tuesday, July 31, 2007 at 11:00 a.m. and
11:15 a.m.  respectively.  The Scheme will also require the subsequent  sanction of the Court and confirmation of the capital reduction
by the Court.  Further  details as to the approvals  required and the persons  entitled to vote at these  meetings are contained in the
Scheme  Document.  Subject to approval at the relevant  meetings and the satisfaction and waiver of the other conditions set out in the
Scheme Document, the Scheme is expected to become effective on or around August 24, 2007.

Timetable

The following  indicative  timetable sets out the key dates for  implementation  of the Proposals.  For further  information on the key
timetable dates for ADS Holders and CDI Holders, please see Parts IV and V of the Scheme Document respectively.

Trading update

Trading for the first half of 2007  remains in line with  Hanson's  expectations,  as set out in  Hanson's  AGM  statement  made in the
Annual General  Meeting of the Company on April 24, 2007,  with  challenging  conditions in North America and the impact of the weak US
dollar broadly offset by improvements in other divisions.

In North America,  aggregates  selling prices have remained robust.  However,  the residential  market remains  difficult and, together
with a prolonged winter season, will result in a challenging first half compared to an unusually strong first half of 2006.

In the UK, both  divisions  have performed  well compared to the first half of 2006,  supported by improved  product  volumes and price
discipline.

Elsewhere, Hanson's operations in Australia, Asia and Continental Europe have enjoyed a good first half.

At this stage, the Company expects  continued  weakness in the US residential  market and adverse foreign exchange to impact the second
half of the year, with trading in divisions elsewhere remaining robust.

the  solicitation  of any vote or approval in any  jurisdiction  pursuant to the  Proposals or otherwise.  The  Proposals  will be made

in respect of the  Proposals.  Any  response to the  Proposals  should be made only on the basis of the  information  contained  in the

The  availability  of the  Proposals to persons who are not resident in the United  Kingdom may be affected by the laws of the relevant
jurisdictions.  Persons who are not so resident  should  inform  themselves  about and observe  any  applicable  requirements  in those
jurisdictions. Further details in relation to overseas shareholders will be contained in the Scheme Document.

The distribution of this  announcement in jurisdictions  other than England and Wales may be restricted by law and therefore persons in
such  jurisdictions  into whose possession this announcement  comes should inform themselves about and observe such  restrictions.  Any
failure to comply with the applicable  restrictions  may constitute a violation of the securities laws of any such  jurisdiction.  This
announcement  has been prepared for the purposes of complying  with English Law, and the  information  disclosed may not be the same as

Hanson and no one else in  connection  with the  Proposals  and will not be  responsible  to anyone other than Hanson for providing the
protections  offered to clients of Rothschild  nor for providing  advice in relation to the Proposals or any other matters  referred to
in this announcement.

The Loan Notes that may be issued  pursuant to the  Proposals  have not been and will not be  registered  under the  Securities  Act or
under the relevant  securities laws of any state or territory or other jurisdiction of the United States.  Accordingly,  Loan Notes may

Lehigh and permitted by applicable law and  regulation,  the Loan Notes may not be offered,  sold,  resold,  transferred,  delivered or
distributed,  directly or indirectly in or into Canada,  Australia or Japan or any other  jurisdiction where to do so would violate the
laws of that jurisdiction or would require registration thereof in such jurisdiction.

has it expressed a view on the accuracy or adequacy of this announcement.

Cautionary note regarding forward-looking statements

This announcement,  including  information  included or incorporated by reference in this announcement,  includes,  or may be deemed to
include,  "forward-looking  statements"  under United States  securities  laws,  including  statements about the expected timing of the
Proposals,  the expected effects on Hanson or  HeidelbergCement of the Proposals,  anticipated  earnings  enhancements,  estimated cost
savings and other synergies,  potential  strategic  options,  plans for and benefits of integration,  estimated  future growth,  market
position and all other  statements in this document  other than  statements of historical  fact.  Forward-looking  statements  include,
without  limitation,  statements  that  typically  contain  words such as "will",  "may",  "should",  "continue",  "aims",  "believes",
"expects",  "estimates",  "intends",  "anticipates",  "projects",  "plans" or similar  expressions.  By their  nature,  forward-looking
statements  involve known or unknown risks,  uncertainties  and other factors because they relate to events and depend on circumstances
that all occur in the future.  Actual results may differ materially from those expressed in the  forward-looking  statements  depending
on a number of factors,  including, but not limited to, the satisfaction of the conditions to the Proposals,  future market conditions,
the  behaviour  of other market  participants,  an adverse  change in the  economic  climate,  a  fluctuation  in the level of clients'
commercial  activity,  appropriate  consultation with employee  representative  bodies, a loss of key personnel and the extent to which
the Hanson and  HeidelbergCement  businesses are successfully  integrated.  In the case of risks  applicable to Hanson,  please see the
Hanson  PLC  Annual  Report  and Form 20-F  2006,  section  entitled  "Principal  risks  and  uncertainties".  Many of these  risks and
uncertainties  relate to factors that are beyond the relevant  companies'  abilities to control or estimate  precisely,  such as future
market  conditions  and the  behaviours  of other  market  participants  and,  therefore  undue  reliance  should not be placed on such
statements.  The  forward-looking  statements  contained or referred to in this announcement are made as of the date hereof and each of
Hanson,  HeidelbergCement  and Lehigh  assumes no  obligation  and does not intend  publicly to update or revise these  forward-looking
statements, whether as a result of future events, new information or otherwise, except as required pursuant to applicable law.

Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Takeover Code, if any person is, or becomes,  "interested"  (directly or indirectly) in one per
cent. or more of any class of "relevant  securities" of Hanson, 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 3.30 p.m.  (London time) on the London business day following the date of the relevant  transaction.  This  requirement will
continue  until the date on which the Scheme becomes  effective or the "offer  period" for the purposes of the Code 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 Hanson, 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 Takeover Code, all "dealings" in "relevant  securities" of Hanson by  HeidelbergCement,  Lehigh
or Hanson,  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 Takeover 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 within this Section headed  "Dealing  Disclosure  Requirements"  are defined in the Takeover Code,  which can
also be found on the Takeover  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 Takeover Panel.
