<p><font size="3" face="Times New Roman">(4)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; That, for purposes of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule&nbsp;424(b)&nbsp;as part of a registration
statement relating to an offering, other than registration statements relying on Rule&nbsp;430B or other than prospectuses filed in reliance on Rule&nbsp;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.</font></p>

<p><font size="3" face="Times New Roman">(5)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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, 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:</font></p>

by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant; (iii)&nbsp;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)&nbsp;Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.</font></p>

<p><font size="3" face="Times New Roman">B.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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&nbsp;13(a) or Section&nbsp;15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section&nbsp;15(d) of the Exchange Act) 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.</font></p>

<p><font size="3" face="Times New Roman">C.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing
provisions, or otherwise,&nbsp; the Company 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.&nbsp; In the event that a claim for indemnification
against such liabilities (other than the payment by the Company in successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the Company 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.</font></p>

Indemnification of Directors and Officers
.
Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation's Board of Directors to grant, indemnification to directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933, as amended.  The Company's Amended and Restated Certificate of Incorporation contains a provision
eliminating the personal liability of the Company's directors to the Company or its stockholders for breach of fiduciary duty as a director to the fullest extent permitted by applicable law.  The Company's Bylaws, as amended, provide for the
indemnification of its directors, officers, employees and other agents to the maximum extent permitted by Delaware General Corporation Law, and the Company has entered into agreements with its officers, directors and certain key employees implementing such
indemnification.

Undertakings
.
A.        The undersigned Registrant hereby undertakes:
II-3
(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 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 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 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,
that paragraphs (a)(1)(i) and (a)(1)(ii) 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 the 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.
(4)        That, for purposes of determining liability under the Securities Act of 1933 to any purchaser, 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, 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:
II-4
(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.
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 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.
C.        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing
provisions, or otherwise,  the Company 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 Company in successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the Company 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.
