LAFARGE NORTH AMERICA INC.<BR>
<U>EMPLOYEE STOCK PURCHASE PLAN</U><BR>
(As Amended and Restated Effective June&nbsp;1, 2005)
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pursuant to the provisions of Section&nbsp;10.2 thereof, the Lafarge North America Inc. Employee
Stock Purchase Plan (As Amended and Restated Effective June&nbsp;1, 2005) (the &#147;Plan&#148;) is hereby amended
in the following respects only:
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>FIRST</U>: Effective June&nbsp;1, 2005, Section&nbsp;5.3(a) of the Plan is hereby amended by
restatement in its entirety to read as follows:
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <I>Authorization</I>. Each Participant&#146;s Enrollment Agreement will authorize payroll
deductions each payday in the manner determined by the Administrative Committee, which
deductions will be equal to a whole dollar amount and/or percentage of the Participant&#146;s
Compensation, but not more than the amount required to pay the Purchase Price under the
right to purchase Common Stock granted under Section&nbsp;5.2. Payroll deductions will begin as
soon as administratively feasible following the Offering Date and will continue until the
Participant&#146;s termination of employment unless (i)&nbsp;the Participant ceases payroll
deductions as provided in Section&nbsp;5.3(b) or (ii)&nbsp;participation is earlier withdrawn or
suspended by the Participant as provided in Section&nbsp;7.1.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>SECOND</U>: Effective June&nbsp;1, 2005, Section&nbsp;6.9 of the Plan is hereby amended by
restatement in its entirety to read as follows:
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.9 <I>Dividends</I>. With regard to dividends declared and paid on shares of Common Stock
held in a Participant&#146;s Share Account at the record date for such dividends, such dividends
will be reinvested in additional shares of Common Stock unless the Participant elects, at
the time and in the manner prescribed by the Administrative Committee, to receive such
dividends in cash. Such dividend reinvestment purchases shall be made from Lafarge or in
the open market on such terms and conditions as may be approved by the Administrative
Committee, but in no event will any discount in the purchase price of shares of Common
Stock provided for under the Plan for regular Plan purchases apply to dividend reinvestment
purchases.
