INDEMNIFICATION

SECTION 8.01.   Survival of Representations, Warranties and
Indemnities.  (a)  Unless this Agreement is earlier terminated pursuant to Article IX, the representations, warranties and indemnities of the Company contained in this Agreement shall survive the Closing Date and remain
in full force and effect until the second anniversary of the Closing Date; provided, however, that Sections 3.03 and 3.13 shall survive indefinitely. Neither the period of survival nor the liability of the Company with respect to
its representations, warranties and indemnities shall be reduced by any investigation made at any time by or on behalf of the Investor. If written notice of a claim has been given prior to the expiration of the applicable representations, warranties
and indemnities by the Investor to the Company, then the relevant

representations, warranties and indemnities shall survive as to such claim, until such claim has been finally resolved.

(b)         Unless this Agreement is earlier terminated pursuant to
Article IX, the representations, warranties and indemnities of the Investor contained in this Agreement shall survive the Closing Date and remain in full force and effect until the second anniversary thereof; provided, however,
that Section 4.04 shall survive indefinitely. Neither the period of survival nor the liability of the Investor with respect to the Investors representations, warranties and indemnities shall be reduced by any investigation made at any time by
or on behalf of the Company.

SECTION 8.02.   Indemnification by the
Company. The Investor and its Affiliates, officers, directors, employees, agents, successors and assigns (each, an Investor Indemnified Party) shall be indemnified and held harmless by the Company for and against any and all
liabilities, losses, damages, claims, costs and expenses, interest, awards, judgments and penalties (including, without limitation, reasonable attorneys and consultants fees and expenses) actually suffered or incurred by them (including,
without limitation, any Action brought or otherwise initiated by any of them) (hereinafter a Loss), arising out of or resulting from the breach of any representation or warranty, covenant or agreement made by the Company contained
in this Agreement. To the extent that the undertakings of the Company set forth in this Section 8.02 may be unenforceable, the Company shall contribute the maximum amount that it is permitted to contribute under applicable Law to the payment
and satisfaction of all Losses incurred by the Investor Indemnified Parties.

SECTION
8.03.  Indemnification by the Investor. The Company and its Affiliates, officers, directors, employees, agents, successors and assigns (each a Company Indemnified Party) shall be indemnified and held harmless by
the Investor for and against any and all Losses arising out of or resulting from the breach of any representation or warranty, covenant or agreement made by the Investor contained in this Agreement. To the extent that the Investors
undertakings set forth in this Section 8.03 may be unenforceable, the Investor shall contribute the maximum amount that it is permitted to contribute under applicable Law to the payment and satisfaction of all Losses incurred by the Company
Indemnified Parties.

SECTION 8.04.  Treatment for Tax Purposes. To
the extent permitted by Law, the Parties agree, solely for Tax purposes, to treat all payments made under this Article VIII, under any other indemnity provision contained in this Agreement, and for any misrepresentations or breach of warranties
or covenants, as adjustments to the consideration paid by the Investor under Article II for all Tax purposes, except to the extent the Law of a particular jurisdiction provides otherwise.

SECTION 8.05.  Limitations on Indemnification. The indemnification obligations of the
Company and the Investor for breach of representation or warranty pursuant to Section 8.02 and Section 8.03, respectively, shall not be effective unless the aggregate dollar amount of all Losses that would otherwise be indemnifiable pursuant thereto
exceeds $1,000,000 (Threshold Amount), at which time the indemnification obligations shall be effective as to all Losses, including the Threshold Amount; provided, however, that the Threshold Amount shall not apply
to any Losses arising out of or relating to Section 3.03. The indemnification

20



---

obligations of the Company and the Investor pursuant to Section 8.02 and 8.03, respectively, shall be effective only until the dollar amount paid in respect of Losses under such Section
aggregates to $10,000,000 and no indemnification pursuant to such provisions shall be payable thereafter.

SECTION   11.10.   No Waiver.  The delay or failure of either Party

limited extent necessary to (i) avoid expiration of a claim, (ii) comply with deadlines under applicable Law, or (iii) obtain interim relief, including injunctive relief, to preserve the status quo or prevent irreparable harm, neither
Party shall file an action or institute legal proceedings with respect to any dispute, controversy, or claim arising out of this Agreement or the validity, interpretation, breach or termination thereof, including claims seeking redress or asserting
rights under any Law, until:

aggrieved Party has given the other Party written notice (Notice of Disagreement), in accordance with Section 11.03 of this Agreement, of its grievance setting forth the basis for such dispute and the remedy
desired;

(b)         the other Party has failed to

agree not to commence any such action, suit or proceeding except in any such court.

SECTION   11.13.   Counterparts.  This Agreement may be executed and
delivered (including by facsimile transmission) in one or more counterparts, and by the different Parties in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one

SECTION   11.14.   Waiver of Jury Trial.  Each of the Company and the
Investor hereby knowingly, voluntarily and irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or any course of conduct,
course of dealing or statements (whether oral or written) or actions of the Company or the Investor in the negotiation, administration, performance or enforcement thereof.

SECTION   11.15.   Construction; Interpretation.  The Parties have
participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of

SECTION   11.16.   Specific Performance.  The Parties hereto agree
