INDEMNIFICATION

Section 6.1                                    Indemnification by the Company. The Company agrees to indemnify each Investor and its Representatives (collectively, “Indemnified Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred (collectively, “Losses”) in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Company contained herein, provided that such claim for indemnification relating to a breach of the representations or warranties is asserted prior to the expiration of such representations or warranties (to the extent such representations or warranties are subject to expiration). No Indemnified Party shall be entitled to recover special, consequential (including lost profits) or punitive damages, provided that any losses recovered by a third party against Indemnified Parties as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Company contained herein shall be included in such Indemnified

21

Party’s losses, regardless of the form of such third party’s losses and whether components of such awards relate to special, consequential or punitive damages. Notwithstanding anything to the contrary, consequential damages shall not be deemed to include diminution in value of the Shares, which is specifically included in damages covered by Indemnified Parties’ indemnification above.

Section 6.2                                    Indemnification Procedure. Promptly after any Indemnified Party has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third Person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (a) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (b) if (i) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (ii) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party.

All notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; at the time of transmittal, if sent via electronic mail; upon actual receipt if sent by certified mail, return receipt requested, or regular mail, if mailed; when receipt acknowledged, if sent via facsimile; and upon actual receipt when delivered to an air courier guaranteeing overnight delivery.

Section 7.6                                    Removal of Legend.

(a)                                 The Company, at its sole cost, shall remove the legend described in Section 4.7 (or instruct its transfer agent to so remove such legend) from the book-entry account evidencing Shares issued and sold to each Investor pursuant to this Agreement if (A) such Shares are sold pursuant to an effective registration statement under the Securities Act, (B) such Shares are sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Company), or (C) such Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as to such securities and without volume or manner of sale restrictions.

(b)                                 In connection with a sale of the Shares by an Investor in reliance on Rule 144, the applicable Investor or its broker shall deliver to the transfer agent and the Company a broker customary representation letter providing to the transfer agent and the Company any information necessary to determine that the sale of the Shares is made in compliance with Rule 144, including, as may be appropriate, a certification that the Investor is not an Affiliate of the Company and regarding the length of time the Shares have been held. Upon receipt of such representation letter, the Company shall promptly direct its transfer agent to direct its transfer agent to remove the legend referred to in Section 4.7 from the appropriate book-entry accounts maintained by the transfer agent, and the Company shall bear all costs associated therewith. After any Investor or its permitted assigns have held the Shares for such time as non-Affiliates are permitted to sell without volume limitations under Rule 144, if the book-entry account for such Shares still bears the restrictive legend referred to in Section 4.7, the Company agrees, upon request of the Investor or permitted assignee, to take all steps necessary to promptly effect the removal of the legend described in Section 4.7 from the Shares, and the Company shall bear all costs associated therewith, regardless of whether the request is made in connection with a sale or otherwise, so long as such Investor or its permitted assigns provide to the Company any information the Company deems reasonably necessary to determine that the legend is no longer required under the Securities Act or applicable state laws, including, without limitation, a certification that the holder is not an Affiliate of the Company (and a covenant to inform the Company if it should thereafter become an Affiliate and to consent to the notation of an appropriate restrictive legend) and regarding the length of time the Shares have been held.

Section 7.7                                    Entire Agreement. This Agreement, the other Operative Documents and the other agreements and documents referred to herein are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and therein. There are no restrictions, promises, representations, warranties or undertakings, other than those set forth or referred to herein or the other Operative Documents with respect to the rights granted by the Company or any of its Affiliates or any Investor or any

25

of its Affiliates set forth herein or therein. This Agreement, the other Operative Documents and the other agreements and documents referred to herein or therein supersede all prior agreements and understandings between the parties with respect to such subject matter.

Section 7.8                                    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to conflict of laws principles (other than Section 5-1401 of the General Obligations Law).

Section 7.9                                    Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

Section 7.10                             Termination.

(a)                                 Notwithstanding anything herein to the contrary, this Agreement may be terminated at any time at or prior to the Closing by any Investor (with respect to such Investor only), upon a breach in any material respect by the Company of any covenant or agreement set forth in this Agreement.

(b)                                 Notwithstanding anything herein to the contrary, this Agreement shall automatically terminate at any time at or prior to the Closing:

(i)                                     if a statute, rule, order, decree or regulation shall have been enacted or promulgated, or if any action shall have been taken by any Governmental Authority of competent jurisdiction that permanently restrains, permanently precludes, permanently enjoins or otherwise permanently prohibits the consummation of the transactions contemplated by this Agreement or makes the transactions contemplated by this Agreement illegal;

(ii)                                  if, under the HSR Act or otherwise, the U.S. Federal Trade Commission or the U.S. Department of Justice shall have commenced or threatened to commence any proceeding to delay or enjoin or seek damages in connection with the transactions contemplated by this Agreement or the Acquisition Agreement;

(iii)                               upon the termination of the Acquisition Agreement; or

(iv)                              if the Closing shall not have occurred by June 1, 2017.

(c)                                  In the event of the termination of this Agreement as provided in this Section 7.10, this Agreement shall forthwith become null and void. In the event of such termination, there shall be no liability on the part of any party hereto, except as set forth in Article VI of this Agreement and this Section 7.10; provided that nothing herein shall relieve any party from any liability or obligation with respect to any willful breach of this Agreement.

26

Section 7.11                             Recapitalization, Exchanges, Etc. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all equity interests of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for or in substitution of, the Shares, and shall be appropriately adjusted for combinations, splits, recapitalizations and the like occurring after the date of this Agreement and prior to the Closing.
