Under the terms of the PSC, ERHC is required to provide a bank guarantee of 50% of the expenditures under the minimum work program.

During the three months ended June 30, 2013, following the approval of ERHC&amp;#8217;s work program in Chad for 2013 and 2014 by the government of Chad, ERHC awarded a contract to perform an Environmental Impact Study (&amp;#8220;EIS&amp;#8221;), required under the PSC, to a local company. ERHC expects the EIS to be completed during the fourth quarter of 2013. As of June 30, 2013, ERHC has applied to the Government of Chad without prejudice to the PSC, to tailor its acreage holding to current determination of prospectivity. If the application is granted, it might reduced certain financial obligation in the PSC.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt; font-weight: bold;"&gt;LEGAL PROCEEDINGS&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt; font-weight: bold;"&gt;JDZ BLOCKS 5 AND 6&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt; font-weight: bold;"&gt;Arbitration and Lawsuit&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt;"&gt;The Company&amp;#8217;s rights in JDZ Blocks 5 and 6 are currently the subject of legal proceedings at the London Court of International Arbitration and the Federal High Court in Abuja, Nigeria. The Company instituted both proceedings in November 2008 against the JDA and the Governments &lt;font style="font-family: ''Times New Roman'', Times, serif; font-size: 10pt;"&gt;of Nigeria and S&amp;#259;o Tom&amp;#233; and Pr&amp;#237;ncipe. The Company seeks legal clarification that its rights in the Blocks remain intact.&lt;/font&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt;"&gt;The issue in contention is entirely contractual. The Company was awarded a 15 percent working interest in each of the Blocks in a 2004/5 bid/licensing round conducted by the JDA following the Company&amp;#8217;s exercise of preferential rights in the Blocks as guaranteed by contract and treaty. The JDA and the Government of STP contend that certain correspondence issued by a previous CEO/President of the Company in 2006 amount to a relinquishment of the Company&amp;#8217;s rights in Blocks 5 and 6 under the Company&amp;#8217;s contracts with STP which provide for the rights. The Company contends that no such relinquishment has occurred and has sought recourse to arbitration accordingly. It also filed the suit to prevent any tampering with its said rights in JDZ Blocks 5 and 6 pending the outcome of arbitration.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt; font-weight: bold;"&gt;Suspension of Proceedings on the Arbitration and Lawsuit&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt;"&gt;&lt;font style="font-family: ''Times New Roman'', Times, serif; font-size: 10pt;"&gt;As of June 30, 2013, the proceedings on the sui&lt;/font&gt;t and the arbitration are currently suspended while the Company pursues amicable settlement with the Governments of Nigeria and S&amp;#259;o Tom&amp;#233; &amp;amp; Pr&amp;#237;ncipe.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt; font-weight: bold;"&gt;Routine Claims&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; color: #000000; font-size: 10pt;"&gt;From time to time, ERHC may be subject to routine litigation, claims, or disputes in the ordinary course of business. ERHC intends to defend these matters vigorously. The Company cannot predict with certainty, however, the outcome or effect of any of the arbitration or litigation specifically described above or any other pending litigation or claims.&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>The entire disclosure for commitments and contingencies.</ElementDefenition><ElementReferences>Reference 1: http://www.xbrl.org/2003/role/presentationRef
