&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;On April 26, 2013, we received correspondence from a stockholder who purchased $10.0 million of shares in our November 2012 public offering asserting a right to rescind the purchase based on violation of securities laws in connection with that offering.&amp;#160; In a related letter dated June 14, 2013, the four underwriters in our November 2012 public offering notified us that they received a letter from the same stockholder in which the stockholder sought to void its purchase of shares in our November 2012 public offering. Pursuant to the terms of the underwriting agreement we entered into with the underwriters in our November 2012 public offering, we could be required to appoint counsel for the underwriters to advise on this matter, subject to their determination that counsel is satisfactory, or, alternatively, we could be required to authorize the underwriters to employ counsel at our expense. We believe the claim is without merit and intend to vigorously defend against it.&amp;#160; No litigation has been commenced in this matter.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;In the normal course of operations, Prospect and its subsidiaries may be subject to litigation. As of June 30, 2013, there were no material litigation matters. The Company holds various insurance policies in an attempt to protect it and investors.&lt;/font&gt;&lt;/p&gt;

We also agreed to compensate The Karlsson Group for certain interest charges imposed on the deferred tax liabilities as a result of the application the &amp;#8220;installment sale&amp;#8221; rules of the Internal Revenue Code. &amp;#160;Based on current tax and interest rates and assuming the entire principal balance remains outstanding through July 1, 2015, the combined cost of these &amp;#8220;gross-up&amp;#8221; payments is estimated at approximately $20.0 million which includes the $17.6 million in liabilities at June 30, 2013 plus our estimates of future tax gross-ups of $1.2 million that would become owing as of January 1, 2014 and 2015 of each year assuming the full principal balance remained outstanding on those dates. &amp;#160;However, this is an estimate only and the amount of the tax gross-up payments is subject to change based on future tax rate changes, changes in certain interest rates published by the Internal Revenue Service and the timing of the debt principal payments.&lt;/font&gt;&lt;/p&gt;

In order to achieve this result, Buffalo agreed to reduce its gross revenue interest in Prospect Global from 2% to 1%.% in exchange for a combination of, at its election, (i) equity securities (that may include common stock, preferred stock or warrants for common stock as mutually agreed) equal in value to the determined fair market value of the gross revenue interest being surrendered or (ii) preferred stock that is redeemable after we commence receiving revenues from the Holbrook Project for the determined fair market value plus accrued interest; provided that in no event will any equity securities or securities convertible into equity securities issued to Buffalo (x) exceed 10% of our outstanding capital stock (in the case of warrants at the time of exercise) or (y) be redeemable for aggregate consideration exceeding 10% of our equity market capitalization at the time of redemption.
