        NOW,
THEREFORE, the Parties agree as follows: 



        SECTION 1.    Amendment.    The Stock Purchase Agreement is hereby amended by replacing Section 7.1(e)
thereof in its entirety as follows: 



        "(e)
by Buyer or Parent by giving written notice to the other party, on or after October 31, 2014 (the "Outside Date"), if the
Closing has not occurred (other than primarily as a result of action or inaction in contravention of this Agreement by the party seeking to terminate this Agreement or its Affiliates) in contravention
of this Agreement." 




        SECTION 2.    Effectiveness of the Amendment; Financing Covenant.    


        (a)   Section 1
of this Amendment shall not become effective unless and until Buyer informs Parent that it has been successful in arranging for the Extended Financing. 


        (b)   Buyer
shall use its reasonable best efforts to arrange for the Extended Financing as soon as practicable; provided,
however, that nothing in this Agreement shall obligate the Buyer to accept terms and conditions from prospective providers of Extended Financing that are substantially less
favorable in the aggregate to Buyer than as set forth in the Commitment Letter. For the avoidance of doubt, the provisions of Section 4.22 of the Stock Purchase Agreement shall apply  mutatis mutandis to any Extended Financing. 


        SECTION 3.    Effect of Amendment.    Except as expressly set forth in Section 1 above, this Amendment
shall not alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Stock Purchase Agreement or any Ancillary Documents, all of
which are ratified and affirmed in all respects and shall continue in full force and effect. Following the date of this Amendment, (a) all references to the Stock Purchase Agreement in the
Stock Purchase Agreement or in any Ancillary Document shall be deemed to be the Stock Purchase Agreement, as amended by this Amendment, and (b) each reference to "hereof", "hereunder" and
"herein" and each other similar reference and each reference to "this Agreement" and each other similar reference contained in the Stock Purchase Agreement shall refer to the Stock Purchase Agreement,
as amended by this Amendment. 


        SECTION 4.    Counterparts.    This Amendment may be executed in any number of counterparts with the same
effect as if all Parties had signed the same document. All counterparts shall be construed together and shall constitute one and the same instrument. Execution and delivery of this Amendment by
exchange of facsimile or other electronically transmitted counterparts (such as "pdf") bearing the signature of a Party shall be equally as effective as delivery of a manually executed counterpart by
such Party. 


        SECTION 5.    Miscellaneous.    The Parties hereby agree that the provisions of Article X of the Stock
Purchase Agreement shall apply mutatis mutandis to the execution and delivery of, the interpretation and construction of, and the performance of the
Parties' respective obligations under, this Amendment.
