<p style="margin:0in 0in .0001pt;text-align:justify;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Registrant&#146;s Bylaws provide that the Registrant is required to indemnify its directors and officers to the fullest extent permitted by the Delaware General Corporation Law. The Registrant&#146;s Bylaws also provide that it shall advance expenses incurred by a director or officer before the final disposition of any action or proceeding upon receipt of an undertaking from or on behalf of that director or officer to repay the advance if it is ultimately determined that he or she is not entitled to be indemnified.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-align:justify;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Registrant has entered into and expects to continue to enter into agreements to indemnify its directors and executive officers as determined by the Registrant&#146;s Board of Directors. These agreements generally provide for indemnification for all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by these individuals and arising out of the their service as the Registrant&#146;s directors or executive officers (or in certain other capacities at the Registrant&#146;s request) to the fullest extent permitted by the Delaware General Corporation Law and to any greater extent that such law may in the future permit. These agreements further provide procedures for the determination of the right to receive indemnification and the advancement of expenses. The Registrant believes that these provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. The Registrant also maintains directors&#146; and officers&#146; liability insurance which reimburses the Registrant for expenses which it may incur in connection with the foregoing indemnity provisions and which may provide direct indemnification to directors and officers where the Registrant is unable to do so.</font></p>

<p style="margin:0in 0in .0001pt;text-align:justify;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to the Registrant&#146;s directors, officers and controlling persons pursuant to the above, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.</font></p>

All reports and definitive proxy or information statements filed pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, after the date of this Registration Statement and prior to the filing of a post-effective amendment 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 into this Registration Statement and to be a part hereof from the date of filing of such documents.

Item 6.  Indemnification of Directors and Officers.
Under Section 145 of the Delaware General Corporation Law, the Registrant can indemnify its directors and officers against liabilities they may incur in such capacities, including liabilities under the Securities Act of 1933.
The Registrant's Certificate of Incorporation contains provisions that limit the liability of its directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, the Registrant's directors will not be personally liable to the Registrant or its shareholders for monetary damages for any breach of fiduciary duties as directors, except liability for the following:
·
Any breach of their duty of loyalty to the Registrant or its stockholders.
·
Acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law.
·
Unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law.
·
Any transaction from which the director derived an improper personal benefit.
The Registrant's Bylaws provide that the Registrant is required to indemnify its directors and officers to the fullest extent permitted by the Delaware General Corporation Law. The Registrant's Bylaws also provide that it shall advance expenses incurred by a director or officer before the final disposition of any action or proceeding upon receipt of an undertaking from or on behalf of that director or officer to repay the advance if it is ultimately determined that he or she is not entitled to be indemnified.
The Registrant has entered into and expects to continue to enter into agreements to indemnify its directors and executive officers as determined by the Registrant's Board of Directors. These agreements generally provide for indemnification for all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by these individuals and arising out of the their service as the Registrant's directors or executive officers (or in certain other capacities at the Registrant's request) to the fullest extent permitted by the Delaware General Corporation Law and to any greater extent that such law may in the future permit. These agreements further provide procedures for the determination of the right to receive indemnification and the advancement of expenses. The Registrant believes that these provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. The Registrant also maintains directors' and officers' liability insurance which reimburses the Registrant for expenses which it may incur in connection with the foregoing indemnity provisions and which may provide direct indemnification to directors and officers where the Registrant is unable to do so.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to the Registrant's directors, officers and controlling persons pursuant to the above, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.

Item 9.  Undertakings.
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 of 1933;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the 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 the 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 and 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 percent 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 the registration statement or any material change to such information in the registration statement;
Provided, however,
(A)
Paragraphs (1)(i) and (1)(ii) of this section do not apply if the registration statement is on Form S-8, and 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 Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.
(2)
That, for the purpose 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.
(4)
That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
(i)
If the Registrant is relying on Rule 430B:
(A)
Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(B)
Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or
II-

(ii)
If the Registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.
(5)
That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
(i)
Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)
Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;
(iii)
The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and
(iv)
Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.
The undersigned Registrant hereby undertakes 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 Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the 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.
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 Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue.
