ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

         Pursuant to a Stock Purchase Agreement dated as of October 2, 1998 (the
"Stock Purchase Agreement") by and between Martin Marietta Materials, Inc. (the
"Registrant") and Redland International Limited ("Redland"), effective at 12:01
a.m. (Eastern Standard Time) on December 4, 1998, the Registrant acquired all of
the issued and outstanding shares of capital stock of Redland Stone Products
Company (the "Company"), all as more particularly described in the Stock
Purchase Agreement.

         The purchase consideration was established by negotiation and consisted
of $272 million in cash plus normal balance sheet liabilities, subject to
certain post-closing adjustments related to working capital, plus approximately
$8 million estimated for certain other assumed liabilities and transaction
costs. The Registrant did not assume any long-term debt of the Company in the
Stock Purchase Agreement. The initial purchase consideration paid at closing was
$272 million. Pursuant to the Stock Purchase Agreement, Redland agreed to
indemnify the Registrant with regard to certain liabilities of the Company. The
Registrant paid the initial purchase consideration from funds obtained from the
issuance of United States commercial paper, a portion of which was repaid with
the proceeds obtained from a private placement of 5.875% Notes due December 1,
2008 issued in the aggregate principal amount of $200 million.

         The Company's operations and business primarily relate to the
production, marketing, distribution and sale of construction aggregates products
and asphaltic concrete. The Registrant intends to operate the Company as a new
division of the Registrant with its headquarters in San Antonio, Texas.
