(c) Effective October 28, 2009, Mr. LoConti, Mr. Clark and the Trust entered into a privately-negotiated transaction with a third party group pursuant to which (1) Mr. LoConti and the Trust purchased 681,002 Shares and 56,622 Shares, respectively, at a price of $4.00 per share, and (2) Mr. LoConti, Mr. Clark and the Trust entered into an option agreement pursuant to which they each had the right in their sole discretion to purchase additional Shares prior to December 25, 2009 at an exercise price of $4.25 per share (the “Option”). Mr. LoConti had the Option to purchase up to 400,000 Shares (in whole or in part). Mr. Clark and the Trust had the Option to purchase up to 347,014 Shares (in whole or in part) and in such amounts between each other as they so agree; provided that the total number of Shares that can be exercised between the two of them could not exceed 347,014 Shares.

On October 29, 2009, Mr. LoConti acquired an aggregate of 41,000 Shares in open market transactions, at the following prices: (i) 10,000 Shares at $3.92, (ii) 10,000 Shares at $3.99, (iii) 15,900 Shares at $4.00, (iv) 5,000 Shares at $4.02, and (v) 100 Shares at $3.98.

On December 31, 2009, in connection with the closing of the Acquisition, the right to acquire the up to 777,778 earn-out Shares was delivered to Live Earth Funding LLC pursuant to the Agreement in satisfaction of

approximately $6.8 million of indebtedness owed by Live Earth to Live Earth Funding LLC as of September 30, 2009.

On August 24, 2010, in connection with the WCA Parties’ receipt of the Ohio Environmental Protection Agency approval of the transactions contemplated by the Agreement, Live Earth made a pro rata distribution of 2,333,335 Shares to its members. As a result, (i) Tower 1 Partnership, LLC, of which the Joseph E. LoConti Trust dated June 2, 2002, is the managing member received 416,000 Shares, (ii) Mr. Clark received 360,444 Shares, (iii) the Gregory J. Skoda Trust, of which Mr. Skoda is the trustee, received 18,889 Shares and (iv) the Trust received 336,667 Shares.

(d) Not applicable.

(e) Not applicable.

Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Ohio law requires that the ownership of the landfill transferred as part of the acquisition be approved by the Ohio Environmental Protection Agency. Because the Ohio approval was not received prior to the closing date, Ohio law requires that the Agreement expressly state that the transactions contemplated by the Agreement are subject to the approval of the Director of the Ohio EPA and contain specific provisions negating such sale in the event that the required Ohio approval is ultimately denied by the Director of the Ohio EPA. In that event, the parties would be required to unwind the transaction, including returning the merger consideration, and, as a result, the 3,000,002 Shares retained by Live Earth at closing were not permitted to be transferred prior to the receipt of such approval. On July 6, 2010, the WCA Parties received the EPA approval.

On December 9, 2009, Mr. LoConti, Mr. Clark, Mr. Skoda and the Trust entered into a Voting Agreement with the Issuer, pursuant to which each agreed to vote its Shares and not to revoke its consent with respect to its membership interests in Live Earth in favor of the Acquisition.

On January 15, 2010, Mr. LoConti, Mr. Clark, the Gregory J. Skoda Revocable Trust and the Trust (collectively, the “Stockholders”) entered into a Stockholders’ Agreement with the Issuer.

The Stockholders’ Agreement provides that, unless approved by a majority of the members of the Board of Directors of the Issuer, the Stockholders will not, subject to certain exclusions, acquire more than 30% of any class of the Issuer’s voting securities (the “Maximum Ownership Limitation”) or sell or transfer Shares representing more than 10% of the Shares in any single transaction or series of related transactions to any person or entity. In addition, the Stockholders have agreed to vote their Shares at all meetings of the Issuer’s stockholders and shall vote such Shares in a manner recommended by the majority of the members of the Issuer’s Board of Directors.

The obligations of the Stockholders under the Stockholders’ Agreement, other than the Maximum Ownership Limitation, terminate in the event that either Tom Fatjo, Jr., the Chief Executive Officer of the Issuer, or Jerome M. Kruszka, the President of the Issuer, are no longer serving in such capacities, respectively. In addition, the Stockholders’ Agreement will terminate on the earlier of (i) January 15, 2015 or (ii) the 180th day after the date on which the Stockholders collectively own voting securities representing less than 5% of the outstanding voting power represented by all of the Issuer’s voting securities then outstanding.

A copy of the Stockholders Agreement is filed as Exhibit 7.5 hereto and is incorporated by reference into this Item 6.
