Corporation Law (the &#147;DGCL&#148;) provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys&#146; fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or
agent to the Company. The DGCL provides that Section&nbsp;145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Section&nbsp;102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation
shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i)&nbsp;for any breach of the director&#146;s duty of loyalty to the corporation or its
stockholders, (ii)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii)&nbsp;for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions,
or (iv)&nbsp;for any transaction from which the director derived an improper personal benefit. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Registrant&#146;s Restated Certificate
of Incorporation provides that, to the fullest extent permitted by the DGCL, a director of the Registrant will not be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director. The Registrant&#146;s
Second Amended and Restated Bylaws provide that, to the maximum extent and in the manner permitted by the DGCL, the Registrant shall indemnify its directors, officers, employees and agents against expenses (including attorneys&#146; fees),
judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding arising by reason of the fact that such person is or was an agent of the Registrant, provided, however, that the Registrant may modify
the extent of such indemnification by individual contracts with its directors and officers and, provided further, that the Registrant shall not be required to indemnify any director or officer in connection with any proceeding (or part thereof)
initiated by such person unless (i)&nbsp;such indemnification is expressly required to be made by law, (ii)&nbsp;the proceeding was authorized in advance by the board of directors of the Registrant, (iii)&nbsp;such indemnification is provided by the
Registrant, in its sole discretion, pursuant to the powers vested in the Registrant under the DGCL or (iv)&nbsp;such indemnification is required to be made pursuant to an individual contract. The Registrant&#146;s Second Amended and Restated Bylaws
also provide that the Registrant may advance the payment of expenses, upon receipt of an undertaking by or on behalf of such person to repay such amounts if it should be determined ultimately that such person is not entitled to be indemnified under
the bylaws or otherwise, and that the indemnification and advancement of expense provisions of the bylaws are nonexclusive. The Registrant maintains director and officer liability insurance covering director and officer indemnification. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Registrant has an Indemnity Agreement with each of its directors and executive officers. The standard for indemnification under the
Indemnity Agreement is substantially the same as under the Registrant&#146;s Second Amended and Restated Bylaws. The Indemnity Agreement, however, provides for the creation of a trust account in the event of a &#147;change in control&#148; (as
defined in the Indemnity Agreement), funded in an amount sufficient to reasonably satisfy any and all expenses incurred by a director or executive officer in connection with investigating, preparing for, participating in, and/or defending any
proceeding relating to any Indemnifiable Event (as defined in the Indemnity Agreement). The trustee of such trust account is to be selected by the director or executive officer receiving the indemnity under the Indemnity Agreement. </P>

Item 3.
Incorporation of Documents by Reference.
The following documents filed with the
Commission by the Registrant are hereby incorporated in this Registration Statement by reference:
•
The Registrant's Annual Report on Form 10-K for the fiscal year ended December 31, 2013 filed with the Commission on February 14, 2014;
•
The Registrant's Current Reports on Form 8-K filed with the Commission on March 21, 2014 and April 21, 2014; and
•
The description of the Registrant's common stock, $0.01 par value per share, contained in the Registrant's current report on Form 8-K, filed with the Commission on June 21, 2005, as such may be amended
from time to time.
Except to the extent that information is deemed furnished and not filed pursuant to securities laws and
regulations, all documents filed with the Commission by the Registrant pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, subsequent to the date hereof and prior to the filing of a post-effective amendment to this Registration
Statement which indicates that all securities offered hereby have been sold, or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference herein and to be a part hereof from the date of filing of such
documents.
Any statement contained herein or incorporated by reference herein shall be deemed to be modified or superseded for purposes

Item 4.

Item 5.
Interests of Named Experts and Counsel.
Not applicable.
Item 6.
Indemnification of Directors and Officers.
Section 145 of the Delaware General
Corporation Law (the "DGCL") provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or
agent to the Company. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.
Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation
shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions,
or (iv) for any transaction from which the director derived an improper personal benefit.
The Registrant's Restated Certificate
of Incorporation provides that, to the fullest extent permitted by the DGCL, a director of the Registrant will not be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director. The Registrant's
Second Amended and Restated Bylaws provide that, to the maximum extent and in the manner permitted by the DGCL, the Registrant shall indemnify its directors, officers, employees and agents against expenses (including attorneys' fees),
judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding arising by reason of the fact that such person is or was an agent of the Registrant, provided, however, that the Registrant may modify
the extent of such indemnification by individual contracts with its directors and officers and, provided further, that the Registrant shall not be required to indemnify any director or officer in connection with any proceeding (or part thereof)
initiated by such person unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was authorized in advance by the board of directors of the Registrant, (iii) such indemnification is provided by the
Registrant, in its sole discretion, pursuant to the powers vested in the Registrant under the DGCL or (iv) such indemnification is required to be made pursuant to an individual contract. The Registrant's Second Amended and Restated Bylaws
also provide that the Registrant may advance the payment of expenses, upon receipt of an undertaking by or on behalf of such person to repay such amounts if it should be determined ultimately that such person is not entitled to be indemnified under
the bylaws or otherwise, and that the indemnification and advancement of expense provisions of the bylaws are nonexclusive. The Registrant maintains director and officer liability insurance covering director and officer indemnification.
The Registrant has an Indemnity Agreement with each of its directors and executive officers. The standard for indemnification under the
Indemnity Agreement is substantially the same as under the Registrant's Second Amended and Restated Bylaws. The Indemnity Agreement, however, provides for the creation of a trust account in the event of a "change in control" (as
defined in the Indemnity Agreement), funded in an amount sufficient to reasonably satisfy any and all expenses incurred by a director or executive officer in connection with investigating, preparing for, participating in, and/or defending any
proceeding relating to any Indemnifiable Event (as defined in the Indemnity Agreement). The trustee of such trust account is to be selected by the director or executive officer receiving the indemnity under the Indemnity Agreement.
Item 7.

Not applicable.
Item 8.
Exhibits.
See Exhibit Index.
II-2
Item 9.
Undertakings.
(a)
The undersigned Registrant hereby undertakes:
(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;
(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. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with
the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the
effective Registration Statement;
(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 the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required
to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant 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 purpose of determining any liability under the Securities Act, 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)
The undersigned Registrant hereby undertakes that, for purposes of determining liability under the Securities Act, 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 herein, 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 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 Commission such indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final adjudication of such issue.
