                           [Form of Face of Security]

                  This Security is a Book-Entry Security within the meaning of
the Indenture hereinafter referred to and is registered in the name of a
Depositary or a nominee of a Depositary. This Security is exchangeable for

transfer of this Security (other than a transfer of this Security as a whole by
the Depositary to a nominee of the Depositary or by a nominee of the Depositary
to the Depositary or another nominee of the Depositary) may be registered except

                  Unless this Note is presented by an authorized representative
of The Depository Trust Company, a New York corporation ("DTC") to the issuer or
its agent for registration of transfer, exchange or payment, and any definitive
Note is issued in the name of Cede & Co. or in such other name as is requested
by an authorized representative of DTC (and any payment is made to Cede & Co. or
to such other entity as is requested by an authorized representative of DTC),
ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY
PERSON IS WRONGFUL in as much as the registered owner hereof, Cede & Co., has an
interest herein.

                  Lafarge Corporation, a corporation duly organized and existing
under the laws of the State of Maryland (herein called the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to
___________________________________, or registered assigns, the principal sum of
________________________ Dollars on _________________________________, and to
pay interest thereon from ________, or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, semi-annually on
____________ and ___________ in each year, commencing ________, at the rate per
annum provided in the title hereof, until the principal hereof is paid or made
available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, which shall be the _______ or ________ (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date.
Any such interest not so punctually paid or duly provided for will forthwith
cease to be payable to the Holder on such Regular Record Date and may either be
paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities of this series not less than 10
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities of this series may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in said Indenture.
As used herein, "Business Day" and "Special Record Date" with respect to any
Interest Payment Date shall be as defined in the Indenture.

                  Payment of the principal of (and premium, if any) and interest
on this Security will be made at the office or agency of the Company maintained
for that purpose in The City of New York, in such coin or currency of the United
States of America as at the time of payment is legal tender for the payment of
public and private debts; provided, however, that at the option of the Company
payment of interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

                  Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof by manual signature,
this Security shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose.

                               LAFARGE CORPORATION
                            ___% Senior Note due ____


                  This Security is one of a duly authorized issue of securities
of the Company (herein called the "Securities"), issued and to be issued in one
or more series under an Indenture, dated as of October 1, 1989 as supplemented
by the Supplemental Indenture dated as of ________, 1998 (herein called the
"Indenture"), between the Company and Citibank, N.A., as Trustee (herein called
the "Trustee", which term includes any successor trustee under the Indenture),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof, limited in aggregate principal amount to $________.

                  These Securities will be redeemable, in whole or in part, at 
the option of the Company, on any date (a "Redemption Date") at a redemption
price equal to the greater of (a) 100% of their principal amount of the
Securities to be redeemed and (b) the sum of the present values of the remaining
scheduled payments of principal and interest thereon (exclusive of interest
accrued to such Redemption Date) discounted to such Redemption Date on a
semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at
the Treasury Rate plus [__] basis points, plus accrued and unpaid interest on
the principal amount being redeemed to such Redemption Date; provided, however,
that installments of interest on Securities that are due and payable on an
Interest Payment Date falling on or prior to the relevant Redemption Date shall
be payable to the holders of such Securities, registered as such at the close of
business on the relevant Record Date according to their terms and provisions of
the Indenture.

   
                  "Treasury Rate" means, with respect to any Redemption Date for
the Securities, (a) the yield, under the heading that represents the average for
the immediately preceding week, appearing in the most recently published
statistical release designated "H.15(519)" or any successor publication that is
published weekly by the Board of Governors of the Federal Reserve System and
that establishes yields on actively traded United States Treasury securities
adjusted to constant maturity under the caption "Treasury Constant Maturities"
for the maturity corresponding to the Comparable Treasury Issue (if no maturity
is within three months before or after the Maturity Date, yields for the two
published maturities most closely corresponding to the Comparable Treasury Issue
shall be determined and the Treasury Rate shall be interpolated or extrapolated
from such yields on a straight-line basis, rounding to the nearest month) or (b)
if such release (or any successor release) is not published during the week
preceding the calculation date or does not contain such yields, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, calculated using a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such Redemption Date. The Treasury Rate shall be calculated
on the third Business Day preceding the Redemption Date.
    

                  "Comparable Treasury Issue" means, the United States Treasury
security selected by the Independent Investment Banker as having a maturity
comparable to the remaining term of the Securities to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities.

                  "Independent Investment Banker" means Donaldson, Lufkin &
Jenrette Securities Corporation, Warburg Dillon Read LLC or Citicorp Securities,
Inc. or, if such firms are unwilling or unable to select the Comparable Treasury
Issue, an independent investment banking institution of national standing
appointed by the Company.

                  "Comparable Treasury Price" means, with respect to any
Redemption Date, (a) the average of four Reference Treasury Dealer Quotations
for such Redemption Date, after excluding the highest and lowest such Reference
Treasury Dealer Quotations, or (b) if the Trustee obtains fewer than four such
Reference Treasury Dealer Quotations, the average of all such Quotations.


<PAGE>   10

                  "Reference Treasury Dealer" means each of Donaldson, Lufkin &
Jenrette Securities Corporation, Warburg Dillon Read LLC or Citicorp Securities,
Inc. and their respective successors; provided however, that if any of the
foregoing shall cease to be a primary U.S. Government securities dealer in New
York City (a "Primary Treasury Dealer"), the Company will substitute therefor
another Primary Treasury Dealer.

                  "Reference Treasury Dealer Quotations" means, with respect to
the Reference Treasury Dealer and any Redemption Date, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third Business Day preceding such Redemption Date.

                  Notice of any redemption by the Company will be mailed at
least 30 days but not more than 60 days before any Redemption Date to each
holder of Securities to be redeemed. If less than all the Securities are to be
redeemed at the option of the Company, the Trustee shall select, in such manner
as it shall deem fair and appropriate, the Securities to be redeemed in whole or
in part.

                  Unless the Company defaults in payment of the redemption
price, on and after any Redemption Date interest will cease to accrue on the
Securities or portions thereof called for redemption.

                  Interest payments for this Security shall be computed and paid
on the basis of a 360-day year of twelve 30-day months.
