<P align="left" style="font-size: 10pt">Risk relating to the lack of an updated consent of Arthur Andersen LLP:



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The consolidated balance sheets of USEC Inc. as of June&nbsp;30, 2001 and the
related consolidated statement of income, stockholders&#146; equity and cash flows
for such period, which are included in the Report on Form 10-K, which is
incorporated by reference herein, was audited by Arthur Andersen LLP. Arthur
Andersen LLP has stopped conducting business before the SEC, has ceased
accounting and audit-related practice and has limited assets available to
satisfy the claims of creditors. Due to the status of Arthur Andersen LLP, we
have not been able to obtain, after reasonable efforts, the written consent of
Arthur Andersen LLP to the inclusion of their report in the Report on Form
10-K, which is incorporated by reference herein, and we have dispensed with the
requirement to file their consent in reliance on Rule&nbsp;437a promulgated under
the Securities Act. Because Arthur Andersen LLP has not consented to the
inclusion of its report in the Report on Form 10-K, which is incorporated by
reference herein, investors&#146; ability to assert claims against Arthur Andersen
LLP may be limited. In particular, because of this lack of consent, investors
will not be able to sue Arthur Andersen under Section&nbsp;11(a)(4) of the
Securities Act for any untrue statements of a material fact contained in, or an
omission to state a material fact required to be stated in, the financial
statements audited by Arthur Andersen LLP that are included in the Report on
Form 10-K, which is incorporated by reference herein.

<P align="left" style="font-size: 10pt"><B>Item&nbsp;6. Indemnification of Directors and Officers.</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the General Corporation Law of the State of Delaware (the
&#147;DGCL&#148;) empowers a Delaware corporation to indemnify any person who was or is a
party to or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation)
by reason of the fact that such person is or was a director, officer, employee
or agent of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The indemnity may
include expenses (including attorney&#146;s fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding, provided that such person acted in good
faith and in a manner such person reasonably believed to be in or not opposed
to the
best interests of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe such person&#146;s conduct was
unlawful.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A Delaware corporation may indemnify directors, officers, employees and
other agents of such corporation in an action by or in the right of the
corporation under the same conditions, except that no indemnification shall be
made if such person is adjudged to be liable to the corporation. Where a
director, officer, employee or agent of the corporation is successful on the
merits or otherwise in the defense of any action, suit or proceeding referred
to in this Item&nbsp;6 or in defense of any claim, issue or matter herein, the
corporation must indemnify such person against the expenses (including
attorney&#146;s fees) which he or she actually and reasonably incurred in connection
therewith.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Both our Bylaws and Certificate of Incorporation require us to indemnify
each of our directors and officers to the fullest extent permitted by law,
subject to certain exceptions, in connection with any actual or threatened
action or proceeding arising out of his or her service to us or to other
organizations at our request.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As permitted by Section&nbsp;102(b)(7) of the DGCL, our Certificate of
Incorporation also contains a provision eliminating the personal liability of a
director to USEC Inc. or our shareholders for monetary damages for breach of
fiduciary duty as a director, subject to certain exceptions.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition to indemnification provided for in our Certificate of

<P align="left" style="font-size: 10pt"><B>Item&nbsp;9. Undertakings.</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The undersigned registrant hereby undertakes:

<P align="left" style="font-size: 10pt">(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:




<P align="left" style="margin-left:10%; font-size: 10pt">(i)&nbsp;to include any prospectus required by Section&nbsp;10(a)(3) of the
Securities Act of 1933;



<P align="left" style="margin-left:10%; font-size: 10pt">(ii)&nbsp;to reflect in the prospectus any facts or events arising after
the effective date of this registration statement (or the most recent
post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set
forth in this registration statement; and



<P align="left" style="margin-left:10%; font-size: 10pt">(iii)&nbsp;to include any material information with respect to the plan of
distribution not previously disclosed in this registration statement
or any material change to such information in this registration
statement;



<P align="left" style="margin-left:2%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;provided, however, that paragraphs (i)&nbsp;and (ii)&nbsp;above do not apply if
the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the registrant
with or furnished to the Commission pursuant to Section&nbsp;13 or Section
15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;That, for the purposes of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.

<P align="left" style="font-size: 10pt">(b)&nbsp;That, for purposes of determining any liability under the Securities Act of
1933, each filing of the registrant&#146;s annual report pursuant to Section 13(a)
or Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan&#146;s annual report pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in this registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.


<P align="left" style="font-size: 10pt">(c)&nbsp;Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

documents. The information incorporated by reference is an important part of
this registration statement, and information that we file later with the SEC
will automatically update and supersede this information. We incorporate by
reference the documents listed below and any future filings made with the SEC
under Sections 13(a), 13(c), 14, or 15(d) of the Securities and Exchange Act of
1934, as amended (the "Exchange Act"), until such time as this registration

Risk relating to the lack of an updated consent of Arthur Andersen LLP:
The consolidated balance sheets of USEC Inc. as of June 30, 2001 and the
related consolidated statement of income, stockholders' equity and cash flows
for such period, which are included in the Report on Form 10-K, which is
incorporated by reference herein, was audited by Arthur Andersen LLP. Arthur
Andersen LLP has stopped conducting business before the SEC, has ceased
accounting and audit-related practice and has limited assets available to
satisfy the claims of creditors. Due to the status of Arthur Andersen LLP, we
have not been able to obtain, after reasonable efforts, the written consent of
Arthur Andersen LLP to the inclusion of their report in the Report on Form
10-K, which is incorporated by reference herein, and we have dispensed with the
requirement to file their consent in reliance on Rule 437a promulgated under
the Securities Act. Because Arthur Andersen LLP has not consented to the
inclusion of its report in the Report on Form 10-K, which is incorporated by
reference herein, investors' ability to assert claims against Arthur Andersen
LLP may be limited. In particular, because of this lack of consent, investors
will not be able to sue Arthur Andersen under Section 11(a)(4) of the
Securities Act for any untrue statements of a material fact contained in, or an
omission to state a material fact required to be stated in, the financial
statements audited by Arthur Andersen LLP that are included in the Report on
Form 10-K, which is incorporated by reference herein.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
Section 145 of the General Corporation Law of the State of Delaware (the
"DGCL") empowers a Delaware corporation to indemnify any person who was or is a
party to or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation)
by reason of the fact that such person is or was a director, officer, employee
or agent of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The indemnity may
include expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding, provided that such person acted in good
faith and in a manner such person reasonably believed to be in or not opposed
to the
best interests of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe such person's conduct was
unlawful.
A Delaware corporation may indemnify directors, officers, employees and
other agents of such corporation in an action by or in the right of the
corporation under the same conditions, except that no indemnification shall be
made if such person is adjudged to be liable to the corporation. Where a
director, officer, employee or agent of the corporation is successful on the
merits or otherwise in the defense of any action, suit or proceeding referred
to in this Item 6 or in defense of any claim, issue or matter herein, the
corporation must indemnify such person against the expenses (including
attorney's fees) which he or she actually and reasonably incurred in connection
therewith.
Both our Bylaws and Certificate of Incorporation require us to indemnify
each of our directors and officers to the fullest extent permitted by law,
subject to certain exceptions, in connection with any actual or threatened
action or proceeding arising out of his or her service to us or to other
organizations at our request.
As permitted by Section 102(b)(7) of the DGCL, our Certificate of
Incorporation also contains a provision eliminating the personal liability of a
director to USEC Inc. or our shareholders for monetary damages for breach of
fiduciary duty as a director, subject to certain exceptions.
In addition to indemnification provided for in our Certificate of
Incorporation and Bylaws, we have entered into indemnification agreements with
our directors and executive officers. We intend to enter into indemnification
agreements with any new directors and executive officers in the future.

Item 9. Undertakings.
The undersigned registrant hereby undertakes:
(a)     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
(i) to include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;
(ii) to reflect in the prospectus any facts or events arising after
the effective date of this registration statement (or the most recent
post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set
forth in this registration statement; and
(iii) to include any material information with respect to the plan of
distribution not previously disclosed in this registration statement
or any material change to such information in this registration
statement;
provided, however, that paragraphs (i) and (ii) above do not apply if
the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the registrant
with or furnished to the Commission pursuant to Section 13 or Section
15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.
(2) That, for the purposes of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.
(b) That, for purposes of determining any liability under the Securities Act of
1933, each filing of the registrant's annual report pursuant to Section 13(a)
or Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in this registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Bethesda, State of Maryland, on this 2nd day of
