INFORMATION CONTAINED IN THIS FORM 6-K REPORT

Excel Maritime Carriers Ltd. (the "Company") has received a notice from Robertson Maritime Investors LLC (“Robertson”), the owner of the 28.6% of Christine Shipco LLC (“Christine Shipco”) not owned by the Company, relating to the Company’s and Robertson’s respective equity interest in Christine Shipco. The notice sent by Robertson alleges, among other things, that the intra-group transfer of the Company's interest in Christine Shipco from Bird Acquisition Co. to the Company as a result of the Company's internal reorganization in 2012 was in violation of Robertson’s right of first refusal in the Limited Liability Company Agreement that governs Christine Shipco and that therefore, the Company did not acquire title to Christine Shipco. Robertson alleges that the Company’s equity interest in Christine Shipco is held in constructive trust for Robertson and also claims damages. Robertson has also asserted that upon a chapter 11 filing, pursuant to the Marshall Islands Limited Liability Company Act of 1996, the Company’s interest in Christine Shipco will terminate. The Company intends to vigorously dispute, and has taken steps to address, these allegations.

The Company’s unaudited financial results for the quarter ended March 31, 2013 are attached hereto as Exhibit 1.

The above description but not the Exhibit attached hereto shall be deemed filed and not furnished.
