(b)           Upon the written request of any Holder (which request shall specify the Registrable Securities intended to be registered by such Holder) made within five (5) Business Days after the receipt of any such Piggyback Offering Notice, the Company will use its commercially reasonable efforts to, subject to the conditions set forth in Section 2.3 and the provision of the information specified in Section 2.5, effect the registration under the Securities Act of the Registrable Securities which the Company has been so requested to register by the Holders thereof to permit the Holders to participate in such underwritten offering.

(c)           Priority in Piggyback Registrations; Right to Withdraw.  If the managing underwriter of an offering pursuant to this Section 2.1 advises the Company that, in its opinion, marketing factors require a limitation on the number of shares of Common Stock (including Registrable Securities requested to be included in such registration) to be included in such registration as contemplated by the Company and the Holders, then the Company shall include in such registration (a) first, 100% of the Common Stock the Company proposes to sell, (b) second, the amount of Registrable Securities requested to be included in such registration pursuant to the registration rights granted by the Company to the parties to that certain First Amended and Restated Investors’ Rights Agreement, dated March 31, 2014, by and among the Company and the other parties thereto, (c) third, the amount of Registrable Securities which the Holders have requested to be included in such registration, such amount to be allocated pro rata among all requesting Holders and all other Persons entitled to registration rights, on the basis of the relative amount of Registrable Securities then held by each such Person, and (d) fourth, shares of Common Stock proposed to be sold by any other Person.  Any Holder requesting to be included in such registration may elect, in writing prior to the effective date of the registration statement filed in connection with such registration, not to register all or any part of such Holder’s Registrable Securities in connection with such registration; provided, however, such election must be made at least five (5) Business Days prior to the effective date of the registration statement. The Company shall have the right

(c)                                  Notification of Claims.  Promptly after receipt by a Person entitled to indemnification pursuant to Section 2.7 (an “Indemnified Party”) hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 2.7, such Indemnified Party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action or proceeding; provided, that the failure of the Indemnified Party to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section 2.7, except to the extent that the indemnifying party is actually prejudiced in any material respect by such failure to give notice.  In case

11

any such action or proceeding is brought against an Indemnified Party, unless in such Indemnified Party’s reasonable judgment, based upon advice of counsel, a conflict of interest between such indemnified and indemnifying parties may exist in respect of such action or proceeding (in which case the Indemnified Party shall have the right to assume or continue its own defense and the indemnifying party shall be liable for any reasonable expenses therefor, the indemnifying party will be entitled to participate in and to assume the defense thereof (at its expense), jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof, the indemnifying party will not be liable to such Indemnified Party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation.  In all cases, the indemnifying party shall have no liability for any settlement made by the Indemnified Party without the prior written consent of the indemnifying party, such consent not to be unreasonably withheld.  No indemnifying party will settle any action or proceeding or consent to the entry of any judgment without the prior written consent of the Indemnified Party, unless such settlement or judgment (i) includes as an unconditional term thereof the giving by the claimant or plaintiff of an unconditional release to such Indemnified Party from all liability in respect of such action or proceeding, (ii) does not involve the imposition of equitable remedies or the imposition of any material obligations on such Indemnified Party, other than as a result of the imposition of financial obligations for which such Indemnified Party will be indemnified hereunder and (iii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of such Indemnified Party.  An Indemnified Party may not settle any action or proceeding or the entry of any judgment without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld or delayed).

(d)                                 Contribution.  (i) If the indemnification provided for in this Section 2.7 from the indemnifying party is unavailable to an Indemnified Party hereunder in respect of any Claim or expenses referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Claim or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and Indemnified Party in connection with the actions which resulted in such Claim or expenses, as well as any other relevant equitable considerations.  The relative fault of such indemnifying party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action.  The amount paid or payable by a party under this Section 2.7(d) as a result of the Claim and expenses referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with any action or proceeding; and (ii) the parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in Section 2.7(d)(i); provided, however that in any case, no Holder will be required to contribute any amount in excess of the gross proceeds after underwriting discounts and commissions received by such Holder upon the sale of the Registrable Securities giving rise to such contribution obligation.  No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

(e)                                  Non-Exclusive Remedy.  The obligations of the parties under this Section 2.7 shall be in addition to any liability which any party may otherwise have to any other party.

SECTION 2.9.  Market Standoff Agreement.  In connection with any underwritten Offering, each Holder who holds Registrable Securities and was offered the opportunity to include Registrable Securities in such Underwritten Offering pursuant to Section 2.1 will agree upon the request of the managing underwriters with respect to such underwritten Offering not to effect any public sale, transfer, short sale, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a public sale, including any sale pursuant to Rule 144 under the Securities Act, of any Common Stock during the 14 day period prior to, and for the period required by the managing underwriters (not to exceed ninety (90) days) after, the effective date of the registration statement for such Underwritten offering (or such lesser period as the managing underwriters may require or permit), except for such Common Stock to be included in such underwritten Offering; provided that all of the Company’s executive officers and all of the members of the Company’s Board of Directors are restricted in the same manner and for the same duration; and provided, further, that no Holder shall be obligated pursuant to this Section 2.9 if less than fifty percent (50%) of the Registrable Securities requested by such Holder to be included in such underwritten Offering were not, in fact, included in such underwritten Offering.
