<div style="TEXT-INDENT: 36pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">As described in the Company&#8217;s quarterly report on Form 10-Q for the quarter ended June 30, 2011, DOE has informed us that it believes that USEC needs to further improve its financial and project execution depth to achieve a manageable credit subsidy cost estimate and to proceed with the DOE loan guarantee. USEC has been working with DOE and DOE&#8217;s advisors on reviewing structuring options to address DOE&#8217;s remaining concerns in order to move forward on the American Centrifuge project and to obtain a conditional commitment and DOE loan guarantee.&#160;In order to address DOE&#8217;s concerns about project execution depth, USEC has developed a project management plan that involves greater participation
by B&amp;W and Toshiba.&#160;&#160;This includes adding B&amp;W and Toshiba personnel in key positions at the project.&#160;&#160;USEC is continuing to work to address DOE&#8217;s concerns regarding the financial depth of the project.&#160;&#160;USEC is also working with its financial and other advisors to review structuring options and strategic alternatives. However, USEC has no assurance that USEC&#8217;s project management plan will be acceptable to DOE or that a structuring option to address DOE&#8217;s remaining concerns or a strategic alternative transaction will be achieved or the timing thereof.&#160;&#160;USEC also has no assurance that any terms USEC negotiates with the DOE Loan Guarantee Program Office will be approved or that the credit subsidy cost will be reasonable, or that USEC will be otherwise able to achieve a conditional commitment in the timeframe
needed.&#160;&#160;USEC anticipates that if a conditional commitment is not obtained by November 1, 2011, USEC will begin demobilization of the project.</font></div>

In the past, we have taken actions to enhance our liquidity and manage our working capital, including working with customers regarding the timing of their orders, including advancement of such orders.&#160;&#160;We expect to continue these efforts and in light of our decision to continue investment in the American Centrifuge project in October 2011, we may need to identify additional measures to enhance our liquidity and manage our working capital,
which may include additional sales of uranium inventories, targeted asset sales, and other measures.&#160;&#160;We have no assurance that we will be successful in enhancing our liquidity and options that we may pursue may have adverse consequences for the long term value of our ongoing operations.</font></div>

that USEC may demobilize the project in November.&#160;&#160;If the project is demobilized, USEC would also incur contract termination and other associated costs.&#160;&#160;In addition, USEC has capitalized significant amounts related to the American Centrifuge project and potential demobilization of the American Centrifuge project could cause USEC to be required to charge to expense amounts previously capitalized related to the American Centrifuge project.&#160;&#160;Capital expenditures related to the American Centrifuge project totaled approximately $1.3 billion as of September 30, 2011.</font></div>

the securities purchase agreement governing the transactions and the right of Toshiba and B&amp;W to terminate the securities purchase agreement if the phase two closing does not occur prior to the expiration of the standstill agreement on October 31, 2011, and the impact of a failure to consummate the transactions on our business and prospects; restrictions in our credit facility that may impact our operating and financial flexibility and spending on the American Centrifuge project; our ability to actively manage and enhance our liquidity and working capital and the potential adverse consequences of any actions taken on the long term value of our ongoing operations; uncertainty regarding the cost of electric power used at our gaseous diffusion plant; the economics of extended Paducah plant operations, including our ability to negotiate an acceptable power arrangement, our ability to
