(Bond Street) and its bank subsidiary,  Florida Community Bank, N.A. (Florida Community Bank). Pursuant to  the Merger Agreement, the Company was to be merged with and into  Bond Street (the Merger) and the Bank was then to merge with and  into Florida Community Bank. On April 22, 2013, the Company and the  Bank entered into Amendment Number 1 to the Merger Agreement (the  Amended Merger Agreement) with Bond Street and Florida Community  Bank. Under the terms of the Amended Merger Agreement, each share  of the Company&amp;#8217;s common stock issued and outstanding  immediately prior to the completion of the merger would have been  converted into the right to receive $&lt;font style=" FONT-SIZE: 10pt"&gt;5.00&lt;/font&gt; in cash at closing.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  On June 11, 2013, the proposed merger was rejected by the  stockholders of the Company. On June 24, 2013, the Company provided  notice to Bond Street that it was terminating the Merger Agreement  pursuant to &lt;font style="BACKGROUND-COLOR: transparent"&gt;provisions  of the Merger Agreement that&lt;/font&gt; &lt;font style="BACKGROUND-COLOR: transparent"&gt;permitted&amp;#160;either the Company  or Bond Street&amp;#160;to terminate the Merger Agreement if  stockholders of the Company did not approve the Merger Agreement by  June 21, 2013.&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;u&gt;Current Litigation Relating to the Merger&lt;/u&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  As described in greater detail in the Proxy Statement of the  Company filed with the Securities and Exchange Commission on May  13, 2013, two putative class action lawsuits related to the  proposed merger were originally filed against the Company, the  Bank, Bond Street and Florida Community Bank and certain directors  of the Company. The two prior lawsuits were voluntarily dismissed  and a new combined federal court action was filed on May 20,  2013.&lt;/div&gt;  &lt;/div&gt;  &lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  On June 5, 2013, Plaintiff Jason Laugherty, individually and on  behalf of a putative class of similarly situated stockholders, the  Company, the Bank, Bond Street, Florida Community Bank, and  individual defendants Forrest W. Sweat, Jr., Charles E. Martin,  Jr., Thomas F. Beeckler, G. Thomas Frankland, John J. Linfante, W.  Eric Palmer, and H. Dennis Woods, entered into a Memorandum of  Understanding (the MOU) regarding the settlement in principle of a  putative class action lawsuit filed in the &lt;font style="BACKGROUND-COLOR: transparent"&gt;United States&amp;#160;District  Court&amp;#160;&lt;/font&gt; &lt;font style="BACKGROUND-COLOR: transparent"&gt;for  the District of Maryland (the Action). The Action was filed in  response to the Merger Agreement and alleged claims against the  Company, the Bank, Bond Street, Florida Community Bank  and&amp;#160;certain directors of the Company for breaches of fiduciary  duties, aiding and abetting breaches of fiduciary duties, and  violations of federal proxy disclosure laws relating to the  proposed merger.&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  Under the terms of the MOU, the Company, the Bank, Bond Street and  Florida Community Bank, the other named individual director  defendants, and the Plaintiff reached an agreement in principle to  settle the class action lawsuit and to release the defendants from  all claims in the Action and the prior lawsuits relating to the  &lt;font style="BACKGROUND-COLOR: transparent"&gt;proposed&amp;#160;merger,  subject to the approval of the&lt;/font&gt; &lt;font style="BACKGROUND-COLOR: transparent"&gt;United States&amp;#160;District  Court&lt;/font&gt; &lt;font style="BACKGROUND-COLOR: transparent"&gt;for  the&amp;#160; &lt;font style="BACKGROUND-COLOR: transparent"&gt;  District&lt;/font&gt; of Maryland and the consummation of the proposed  merger. Under the terms of the MOU, Plaintiff&amp;#8217;s counsel also  reserved the right to seek an award of attorney&amp;#8217;s fees and  expenses if the&lt;/font&gt; &lt;font style="BACKGROUND-COLOR: transparent"&gt;  proposed&amp;#160;merger was not approved by the Company&amp;#8217;s  stockholders.&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  On June 7, 2013, the parties to the MOU submitted a joint motion to  stay the Action and/or to extend case deadlines pending  consummation of the &lt;font style="BACKGROUND-COLOR: transparent"&gt;  proposed merger and the filing of a motion for a preliminary  approval of settlement. The court granted the motion and stayed the  Action pending consummation of the merger. Although the vote on the  proposed merger transaction was unsuccessful, the Action remains  pending. The Company continues to believe the lawsuit is meritless  and intends to vigorously defend against any remaining  claims.&lt;/font&gt;&lt;/div&gt;  &lt;/div&gt;  &lt;/div&gt;        </NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>Disclosure of a proposed merger agreement, which is contingent upon certain regulatory approvals and shareholder approval.</ElementDefenition><ElementReferences>No definition available.</ElementReferences><IsTotalLabel>false</IsTotalLabel><UnitID>0</UnitID><Label>Merger Agreement Proposed [Text Block]</Label></Row></Rows><Footnotes /><IsEquityReport>false</IsEquityReport><ReportName>MERGER AGREEMENT WITH BOND STREET HOLDINGS, INC.</ReportName><MonetaryRoundingLevel>UnKnown</MonetaryRoundingLevel><SharesRoundingLevel>UnKnown</SharesRoundingLevel><PerShareRoundingLevel>UnKnown</PerShareRoundingLevel><ExchangeRateRoundingLevel>UnKnown</ExchangeRateRoundingLevel><HasCustomUnits>true</HasCustomUnits><IsEmbedReport>false</IsEmbedReport><IsMultiCurrency>false</IsMultiCurrency><ReportType>Sheet</ReportType><RoleURI>http://www.atlanticcoastbank.net/role/MergerAgreementWithBondStreetHoldingsInc</RoleURI><NumberOfCols>1</NumberOfCols><NumberOfRows>2</NumberOfRows></InstanceReport>
