Leo C. Farrenkopf, Jr., Esq., Vice President, Secretary and Assistant General Counsel of the Registrant, has rendered an opinion as to the legality of the issuance of additional shares of common stock offered pursuant to this Registration Statement.  Mr. Farrenkopf owns substantially less than 1% of the Registrant's shares of common stock.
Item 6. Indemnification of Directors and Officers.
Limitation on Liability of Directors
Pursuant to authority conferred by Section 102 of the Delaware General Corporation Law ("
DGCL
"), Paragraph 11 of the Registrant's  Restated Certificate of Incorporation ("
Paragraph 11
") eliminates the personal liability of Registrant's directors to the Registrant or its stockholders for monetary damages for breach of fiduciary duty including, without limitation, directors serving on committees of the Registrant's Board of Directors.  Directors remain liable for (1) any breach of the duty of loyalty to the Registrant or its stockholders, (2) any act or omission not in good faith or which involves intentional misconduct or a knowing violation of law, (3) any violation of Section 174 of the DGCL, which proscribes the payment of dividends and stock purchases or
redemption under certain circumstances, and (4) any transaction from which directors derive an improper personal benefit.
Indemnification and Insurance
In
    accordance with Section 145 of the DGCL, which provides for the indemnification
    of directors, officers and employees under certain circumstances, Paragraph
    11 grants the Registrant's directors and officers a right to indemnification
    for all expenses, liabilities and losses relating to civil, criminal, administrative
    or investigative proceedings to which they are a party (1) by reason of the
    fact that they are or were directors or officers of the Registrant, or (2)
    by reason of the fact that, while they are or were directors or officers
    of the Registrant, they are or were serving at the request of the Registrant
    as directors or officers of another corporation, partnership, joint venture,
    trust or enterprise. Paragraph 11 further provides for the mandatory advancement
    of expenses incurred by officers and directors in defending such proceedings
    in advance of their final disposition upon  delivery to the Registrant by
    the Indemnitee of an undertaking to repay all amounts so advanced if it is
    ultimately determined that such Indemnitee is not entitled to be indemnified
    under Paragraph 11. The Registrant may not indemnify or make advance payments
    to any person in connection with proceedings initiated against the Registrant
    by such person without authorization of the Registrant's Board of Directors.
In addition, Paragraph 11 provides that the directors and officers therein described shall be indemnified to the fullest extent permitted by Section 145 of the DGCL, or any successor provisions or amendments thereunder.  In the event that any such successor provisions or amendments provide indemnification rights broader than permitted prior thereto, Paragraph 11 allows such broader indemnification rights to apply retroactively with respect to any predating alleged action or inaction and also allows the indemnification to continue after an
Indemnitee has ceased to be a director or officer of the Registrant and to inure to the benefit of the Indemnitee's heirs, executors and administrators.
Paragraph 11 further provides that the right to indemnification is not exclusive of any right which any Indemnitee may have or thereafter acquire under any statute, the Registrant's  Restated Certificate of Incorporation, any agreement or vote of stockholders or disinterested directors or otherwise, and allows the Registrant to indemnify and advance expenses to any person whom the Registrant has the power to indemnify under the DGCL or otherwise.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted for directors and officers and controlling persons pursuant to the foregoing provisions, 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.
The Registrant's  Restated Certificate of Incorporation authorizes the Registrant to purchase insurance for directors and officers of the Registrant and persons who serve at the request of the Registrant as directors, officers, employees or agents of another corporation, partnership, joint venture, trust, or enterprise, against any expense, liability or loss incurred in such capacity, whether or not the Registrant would have the power to indemnify such persons against such expense or liability under the DGCL.  The Registrant intends to maintain insurance coverage of its officers and directors as well as insurance coverage to reimburse the Registrant for potential costs of its corporate indemnification of directors and officers.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
See Exhibit Index.
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; 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 the undertakings set forth in paragraphs (1)(i) and (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 by 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 liabilities 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; and
(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 any 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 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 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 of 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.
