Re:                 Notice of Nomination

Dear Mr. Wason:

The right of shareholders to nominate directors, and the right of other shareholders to vote on the election of such nominees, are fundamental to corporate governance under New Jersey law. The efforts of Vulcan Materials Company (“Vulcan”) to subvert these rights, most recently manifested in your letter to me of April 4, 2012, contravene New Jersey law, violate the fiduciary duties of Vulcan’s management and Board, and are disrespectful of Vulcan’s shareholders. Indeed, Martin Marietta Materials, Inc.’s (“Martin Marietta”) lawsuit in New Jersey against Vulcan predicted that Vulcan would conjure up some issues concerning the nominees with the goal of disenfranchising its shareholders. Unfortunately, that appears to have been a sound prediction. Neither Martin Marietta nor, we believe, other Vulcan shareholders will sit idly by and let that happen.

Your letter continues to raise completely unsupportable suspicions about the independence of the proposed director nominees and alternate nominees (“Nominees”) of Martin Marietta and whether proper disclosure was made to Vulcan. The illegitimacy of this effort is demonstrable:

• Your ostensible concern about independence and disclosure is belied by your complete lack of timeliness in asserting any concern. You have had in your possession the responses of the Nominees to Vulcan’s questionnaires since February 13, 2012, and the confidentiality agreements that were entered into between Martin Marietta’s counsel, Skadden, Arps, Slate, Meagher & Flom LLP, and each of the Nominees (the “Agreements”) since February 27, 2012. Yet you failed to raise any so-called issues about the Nominees for more than a month.

• On the face of the Agreements the Nominees never agreed to be “Representatives” of Martin Marietta on Vulcan’s Board and the Agreements have no bearing whatsoever on their independence.

• The Agreements in no way restrict the Nominees from exercising their fiduciary duties solely as directors of Vulcan if and when they are elected.

In sum, the Agreements present no issues regarding the Nominees and never have. Moreover, Martin Marietta’s process with respect to the Nominees has been, and continues to be, in full compliance with the applicable requirements of New Jersey law, the Securities and Exchange Commission and Vulcan. Vulcan’s shareholders deserve the opportunity to consider the Nominees on their merits as director candidates fully prepared and able to exercise completely independent judgment solely in the interests of Vulcan and its shareholders. To further that outcome, although certainly not necessary in light of the foregoing, Martin Marietta confirms that the Nominees have no continuing obligations to it under the Agreements. In addition, copies of the Agreements are enclosed per your request (a form of which is also being filed with the Securities and Exchange Commission). These actions should make clear to all that these Agreements are of no moment and Vulcan’s actions to suggest otherwise are a feeble attempt to create a smokescreen.

For the record, the delivery of this letter shall not be deemed to constitute an admission by Martin Marietta that any notice with respect to the Nominees was or is in any way defective, or a waiver by Martin Marietta of its right, in any way, to contest or challenge any of the foregoing matters. In addition, the delivery of this letter is not an admission that the procedures set forth in Vulcan’s Bylaws are legal, valid or binding, and Martin Marietta reserves all rights in connection with such matters and the other matters addressed in this letter.

Sincerely,
MARTIN MARIETTA MATERIALS, INC.

CONFIDENTIALITY AGREEMENT

This agreement (“Agreement”) is between [—], an individual residing at [—] (“Recipient”), and a company to be named (the “Company”) that is represented by Skadden, Arps, Slate, Meagher & Flom LLP.

WHEREAS, the Recipient is being considered as a possible nominee of the Company to serve on the Board of Directors (the “Board”) of a U.S. based company listed on a national securities exchange to be identified to you following an initial screening process (“Target”);¹

WHEREAS, in order to facilitate discussions regarding the consideration of Recipient for nomination to Target’s Board, the Recipient may receive certain confidential, proprietary and/or non-public information pertaining to the Company and a potential proxy contest, exchange offer or other transaction between Company and Target (“Potential Transaction”), which the Company desires to protect against unauthorized disclosure and improper use; and

WHEREAS, the Company will seek your views in connection with the Potential Transaction described herein.

NOW THEREFORE, in consideration of the covenants herein contained, the parties agree as follows:

1.    As used herein “Proprietary Information” means any information, communication or data regarding the Company’s businesses, financial condition, operations, assets and liabilities and any notes, records or other documents and materials that contain, reflect, are based on or are generated from any such information, communication or data. Proprietary Information shall also include any information, communication or data regarding a Potential Transaction (including, without limitation, that you are being considered for, or may become, a nominee of the Company, the existence or terms of this Agreement or any other arrangement or discussions between you and the Company or its Representatives, and the status of any such Potential Transaction) that has been or may be provided or made available to Recipient by the Company or any of its directors, officers, employees, agents, advisors or other representatives (“Representatives”) orally, in writing, electronically or to which the Recipient has access by way of inspection, observation or otherwise.

2.    Recipient will not disclose any information, communication or data received from the Company or its Representatives, including Proprietary Information in any manner whatsoever without the prior written approval of the Company. Recipient will not use Proprietary Information for any purpose other than for the benefit of the Company in connection with the Potential Transaction (the “Purpose”).

3.    All Proprietary Information which has been or will be disclosed to the Recipient shall be deemed proprietary and subject to the terms of this Agreement unless specifically documented in writing by the Company that said communication is non-proprietary.

¹  Screening process will consist of, among other things, completion of a questionnaire involving a group of potential targets and a background check.

4.    The obligations imposed by this Agreement will not apply with respect to any Proprietary Information required to be disclosed by Recipient pursuant to an order of a court of competent jurisdiction, provided that the Recipient promptly notifies the Company of such order to allow the Company to contest such disclosure.

5.    This Agreement and the obligations hereunder shall terminate on the later of three (3) years after the effective date of this Agreement or Recipient’s last date of service on the Board, if elected; provided that if Recipient is elected to the Board, Recipient may disclose or use such Proprietary Information to the extent, in the written opinion of counsel, such disclosure or use is required by applicable law or exchange listing requirements.

6.    Recipient acknowledges that it is aware that applicable United States securities laws prohibit any person who has material nonpublic information about a company from purchasing or selling securities of such company or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities.

7.    You acknowledge that the Proprietary Information is confidential and disclosure of Proprietary Information to third parties, or use of Proprietary Information other than as expressly permitted herein, may be expected to cause harm to the Company. You agree that the Company shall be entitled to equitable relief, including injunctive relief and specific performance, in the event of any breach of the provisions of this letter agreement.

8.    This Agreement shall be governed by the laws of the State of New York and any suit brought by either party against the other party for claims arising out of this Agreement will be brought in the federal and/or state courts sitting therein.

9.    Upon the written request and instruction of the Company, all Proprietary Information in the possession of the Recipient shall be returned to the Company.

10.    Recipient will agree to be bound as a “Representative” of the Company under the terms of the confidentiality agreement between the Company and the Target for so long as such agreement remains in effect.

11.    This Agreement constitutes the entire agreement between the parties with respect to the disclosure(s) of Proprietary Information. Any amendments to this Agreement must be in writing and executed by authorized representatives of each party.

IN WITNESS WHEREOF, this Agreement has been duly executed by the parties hereto and shall become effective as of November     , 2011:
