Summary

Vulcan Shareholders Should Show Their Support for Martin Marietta's

Compelling Offer

Martin Marietta believes that:

•

There

is

undeniable

strategic

logic

in

the

combination

of

Martin

Marietta

and

Vulcan

•

Vulcan’s claims of undervaluation ignore the fact that Vulcan shareholders are

not cashing out, but rather maintaining ~58% ownership in a stronger entity

•

Vulcan continues to mask underperformance and value destruction while

refusing to accept Martin Marietta’s invitation to engage in discussions

•

Vulcan

shareholders

have

an

opportunity

to

send

a

strong

message

to

their

Board

–

Elect Martin Marietta’s independent nominees to the Vulcan Board

–

Communicate support for the transaction to fellow shareholders

4

Martin Marietta’s Proposal is a 100% Stock-for-Stock Combination,

With Vulcan Shareholders Retaining ~58% Ownership

Note 1:

Vulcan implied TEV/2012E EBITDA based on 0.50 of a Martin Marietta share of common stock for each Vulcan share of common stock (as of 4/27/2012).  EBITDA projections based on

Thomson median consensus estimates as of 4/27/2012.

Martin Marietta’s

Proposed Stock-for-Stock

Combination

Cash Acquisition

Less important as parties ride economic

cycle together

Realized and shared

No incremental leverage related to financing

of transaction

Shared by both parties

Meaningful premium to the unaffected price

Opportunistic timing is critical

Accrue to buyer only

Burden increases for buyer

Seller does not participate in future upside

Typically higher than transactions with stock

or mixed consideration

Vulcan’s statements about value for its shareholders fundamentally mischaracterize Martin

Marietta’s proposal, ignoring the shared upside of a stock-for-stock combination

The offer:

–

Does

not

undervalue

Vulcan;

it

provides

an

immediate

premium

to the unaffected price and

values

Vulcan at a 2012 EBITDA

multiple

of

16.7x

while

Martin

Marietta

is

trading

at

–

Does not exploit cyclical lows; Vulcan’s share price already reflects expected recovery given

Note 1:

Source: Vulcan’s “The Vulcan Value Proposition”, March 2012.

Note 2:

Martin Marietta continues to believe that it can achieve $200 to $250 million of annual cost synergies as a result of the combination.  With respect to the purported savings programs announced by

Vulcan since December 12, 2011, Martin Marietta believes that Vulcan’s programs will be far from fully effective, at best, for several years, and not necessarily sustainable, although they may

result in some level of cost reductions during this period.  Martin Marietta’s belief is based on Martin Marietta’s understanding of the design and attempted implementation to date of Vulcan’s

programs and Martin Marietta’s experience in implementing its own fully operational management reporting system.  Moreover, Martin Marietta believes that Vulcan’s senior management lacks

demonstrated capability and discipline to be credible to deliver Vulcan’s “hope plan” on a standalone basis, leaving Vulcan shareholders exposed to substantial execution risk.  Actual synergies will

be based on future performance, as to which there can be no assurance.

…But Management Credibility is Essential

Martin Marietta believes that:

Vulcan has masked underperformance and value destruction:

•

Relied on flawed operating comparisons

•

Mischaracterized the historical performance of its businesses

Vulcan

continues

to

use

“smokescreen”

tactics

to

impede

a

transaction:

•

Ignored

its

own

elevated

trading

multiple,

which

Martin

Marietta

believes

already

reflects the potential benefits of an eventual economic recovery

•

Set unrealistic expectations for the relative timing and extent of Vulcan's

recovery

•

Created vague “hope plans”

as a response to Martin Marietta’s proposal

•

Disregarded Vulcan’s 26% stock price increase (approximately $1.1 billion in

equity

value)

since

12/9/2011,

which

appears

to

have

been

driven

by Martin

Marietta’s proposal

The Election of Martin Marietta’s Independent Director Nominees is

The Important Next Step for a Successful Transaction

•

Martin Marietta has nominated 4 independent director candidates

to the Vulcan Board who would replace the 4 incumbent Vulcan

directors seeking re-election

•

Election of Martin Marietta’s independent nominees will bring a

fresh perspective

–

including an open mind

–

to the Vulcan

Boardroom on whether Vulcan should engage with Martin Marietta

on its business combination

32

This election provides a critical opportunity to the Vulcan shareholders

to show support for a combination of the two companies

•

In contrast, a vote for the incumbent Board members is a

vote for the status quo, encouraging the current Vulcan Board

to continue to ignore value creating opportunities for

shareholders

Qualified and Independent Board Nominees

•

Martin Marietta has proposed qualified, independent Board nominees

•

Each nominee has been carefully screened to ensure independence

–

No affiliation with Martin Marietta, Vulcan or any of their subsidiaries

Cautionary Note Regarding Forward-Looking Statements

41

This presentation may include "forward-looking statements." Statements that include words such as "anticipate," "expect," "should be," "believe," "will," and other words

of similar meaning in connection with future events or future operating or financial performance are often used to identify forward-looking statements. All statements

in this presentation, other than those relating to historical information or current conditions, are forward-looking statements. These forward-looking statements are

subject to a number of risks and uncertainties, many of which are beyond Martin Marietta's control, which could cause actual results to differ materially from such

statements. Risks and uncertainties relating to the proposed transaction with Vulcan include, but are not limited to: Vulcan's willingness to accept Martin Marietta's

proposal and enter into a definitive transaction agreement reasonably satisfactory to the parties; Martin Marietta's ability to obtain shareholder, antitrust and other

approvals on the proposed terms and schedule; uncertainty as to the actual premium that will be realized by Vulcan shareholders in connection with the proposed

transaction; uncertainty of the expected financial performance of the combined company following completion of the proposed transaction; Martin Marietta's ability to

achieve the cost-savings and synergies contemplated by the proposed transaction within the expected time frame; Martin Marietta's ability to promptly and effectively

integrate the businesses of Vulcan and Martin Marietta; the combined company’s ability to pay dividends in the amounts anticipated; a downgrade of the credit rating of

Vulcan's indebtedness, which could give rise to an obligation to redeem Vulcan's existing indebtedness; the potential implications of alternative transaction structures

with respect to Vulcan, Martin Marietta and/or the combined company, including potentially requiring an offer to repurchase certain of Martin Marietta's existing

debt;  the implications of the proposed transaction on certain of Martin Marietta’s and Vulcan’s employee benefit plans; and disruption from the proposed transaction

making it more difficult to maintain relationships with customers, employees or suppliers. Additional risks and uncertainties include, but are not limited to: the

performance of the United States economy; decline in aggregates pricing; the inability of the U.S. Congress to pass a successor federal highway bill; the discontinuance

of the federal gasoline tax or other revenue related to infrastructure construction; the level and timing of federal and state transportation funding, including federal

stimulus projects; the ability of states and/or other entities to finance approved projects either with tax revenues or alternative financing structures; levels of

construction spending in the markets that Martin Marietta and Vulcan serve; a decline in the commercial component of the nonresidential construction market, notably

office and retail space; a slowdown in residential construction recovery; unfavorable weather conditions, particularly Atlantic Ocean hurricane activity, the late start to

spring or the early onset of winter and the impact of a drought or excessive rainfall in the markets served by Martin Marietta and Vulcan; the volatility of fuel costs,

particularly diesel fuel, and the impact on the cost of other consumables, namely steel, explosives, tires and conveyor belts; continued increases in the cost of other

repair and supply parts; transportation availability, notably barge availability on the Mississippi River system and the availability of railcars and locomotive power to

move trains to supply Martin Marietta's and Vulcan's long haul distribution markets; increased transportation costs, including increases from higher passed-through

energy and other costs to comply with tightening regulations as well as higher volumes of rail and water shipments; availability and cost of construction equipment in

the United States; weakening in the steel industry markets served by Martin Marietta's dolomitic lime products; inflation and its effect on both production and interest

costs; Martin Marietta’s ability to successfully integrate acquisitions and business combinations quickly and in a cost-effective manner and achieve anticipated

profitability to maintain compliance with Martin Marietta's leverage ratio debt covenants; changes in tax laws, the interpretation of such laws and/or administrative

practices that would increase Martin Marietta's and/or Vulcan's tax rate; violation of Martin Marietta's debt covenant if price and/or volumes return to previous levels of

instability; a potential downgrade in the rating of Martin Marietta's or Vulcan’s indebtedness; downward pressure on Martin Marietta's or Vulcan's common stock price

and its impact on goodwill impairment evaluations; the highly competitive nature of the construction materials industry; the impact of future regulatory or legislative

actions; the outcome of pending legal proceedings; healthcare costs; the amount of long-term debt and interest expense; changes in interest rates; volatility in pension

plan asset values which may require cash contributions to pension plans; the impact of environmental clean-up costs and liabilities relating to previously divested

businesses; the ability to secure and permit aggregates reserves in strategically located areas; exposure to residential construction markets; and the impact on the

combined company (after giving effect to the proposed transaction with Vulcan) of any of the foregoing risks, as well as other risk factors listed from time to time in

Martin Marietta's and Vulcan's filings with the SEC.

The foregoing review of important factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are

included elsewhere, including the Risk Factors section of the Registration Statement and our most recent report on Form 10-K, and any other documents of Martin

Marietta and Vulcan filed with the SEC.  Any forward-looking statements made in this presentation are qualified in their entirety by these cautionary statements, and

there can be no assurance that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected

consequences to, or effects on, us or our business or operations.  Except to the extent required by applicable law, we undertake no obligation to update publicly or

revise any forward-looking statement, whether as a result of new information, future developments or otherwise.
