1.Resale Registration Shelf Registration.

(a)Procedures and Expenses.

(i)No later than five Business Days following the date hereof (the “Filing Date”), the Purchaser will file with the SEC a registration statement (together with the related prospectus, amendments and supplements to such registration statement, and including pre- and post-effective amendments, and all exhibits and material incorporated by reference in such registration statement, the “Registration Statement”) on Form S-1 covering the resale of all Registrable Securities; provided, however, that, Purchaser’s obligation to include the Registrable Securities of any particular Seller in the Registration Statement will be expressly conditioned upon Purchaser’s prior receipt of information and materials regarding such Seller as specified in Section 1(a)(xii).

(ii)The Purchaser will use its commercially reasonable efforts to cause the Registration Statement to be declared effective as soon as practicable and in any event within the earlier of: (i) 30 days following the Filing Date and (ii) five Business Days after the date the Company receives written notification from the SEC that the Registration Statement will not be reviewed (or, in the event the staff of the SEC (“Staff”) reviews and has written comments to the Registration Statement, within 90 days following the Filing Date) (the earlier of the foregoing or the applicable date set forth in Section 1(a)(ix), the “Effectiveness Deadline”), such efforts to include, without limiting the generality of the foregoing, preparing and filing with the SEC any financial statements or other information that is required to be filed prior to the effectiveness of such Registration Statement.

(iii)Not less than three Trading Days prior to the filing of the Registration Statement or any related prospectus or any amendment or supplement thereto, the Purchaser will furnish

via email to the Seller Representative copies of all such documents proposed to be filed, which documents (other than any document that is incorporated or deemed to be incorporated by reference therein) will be subject to the review of the Seller Representative. The Purchaser will reflect in each such document when so filed with the SEC such comments regarding the Sellers and the plan of distribution as the Seller Representative may reasonably and promptly propose no later than two Trading Days after the Seller Representative has been so furnished with copies of such documents as aforesaid.

(iv)The Purchaser will promptly prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective and free from any material misstatement or omission to state a material fact therein until termination of such obligation as provided in Section 1(d) below, subject to the Purchaser’s right to suspend pursuant to Section 1(b). Further, the Purchaser covenants that it will file any reports required to be filed by it under the Securities Act and the Exchange Act and will take such further action as the holders thereof may reasonably request, all to the extent required from time to time to enable such holders to sell such Purchaser Common Stock without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 under the Securities Act, as such rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the SEC.

(v)The Purchaser will furnish to the Sellers such number of copies of prospectuses in conformity with the requirements of the Securities Act and such other documents as the Sellers may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Registrable Securities by the Sellers.

(vi)The Purchaser will file such documents as may be required of the Purchaser for securities law clearance for the resale of the Registrable Securities in such states of the United States as may be reasonably requested by the Sellers and use its commercially reasonable efforts to maintain such blue sky qualifications during the period the Purchaser is required to maintain effectiveness of the Registration Statement; provided, however, that the Purchaser will not be required in connection with this Section 1(a)(vi) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented.

(vii)Upon notification by the SEC that the Registration Statement will not be reviewed or is not subject to further review by the SEC, the Purchaser will within three Trading Days following the date of such notification request acceleration of such Registration Statement (with the requested effectiveness date to be not more than two Trading Days later).

(viii)Upon notification by the SEC that that the Registration Statement has been declared effective by the SEC, the Purchaser will file the final prospectus under Rule 424 of the Securities Act within the applicable time period prescribed by Rule 424.

(ix)The Purchaser will advise the Seller Representative promptly (and in any event within two Trading Days thereof):

(A)of the effectiveness of the Registration Statement or any post-effective amendments thereto;

(B)of any request by the SEC for amendments to the Registration Statement or amendments to the prospectus or for additional information relating thereto;

(C)of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement under the Securities Act or of the suspension by any state securities SEC of the qualification of the Registrable Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes; and

(D)of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Registration Statement, the prospectus and amendment or supplement thereto, or any document incorporated by reference therein, untrue, or that requires the making of any additions to or changes in the Registration Statement or the prospectus in order to make the statements therein not misleading.

(x)The Purchaser will cause all Shares to be listed on each securities exchange, if any, on which equity securities by the Purchaser are then listed.

(xi)The Purchaser will bear all expenses in connection with the procedures in paragraphs (i) through (x) of this Section 1(a) and the registration of Registrable Securities on such Registration Statement and the satisfaction of the blue sky laws of such states.

(xii)Each Seller will furnish to the Purchaser such information regarding such Seller, the Registrable Securities held by such Seller and the offer and sale or other distribution proposed by such Seller as Purchaser may reasonably request and as will be required in connection with any registration, qualification or compliance contemplated by this Section 1 (including, for the avoidance of doubt, as may be required under Applicable Laws in order to permit Purchaser to comply with all applicable requirements of the Securities Act and the Exchange Act in connection with the registration of all Registrable Securities held by such Seller under the Securities Act).

(b)Prospectus Suspension. Each Seller acknowledges that there may be times when the Purchaser must suspend the use of the prospectus forming a part of the Registration Statement until such time as an amendment to the Registration Statement has been filed by the Purchaser and declared effective by the SEC, or until such time as the Purchaser has filed an appropriate report with the SEC pursuant to the Exchange Act. Each Seller hereby covenants that it will not sell any Registrable Securities pursuant to said prospectus during the period commencing at the time at which the Purchaser gives the Sellers notice of the suspension of the use of said prospectus and ending at the time the Purchaser gives the Sellers notice that the Sellers may thereafter effect sales pursuant to said prospectus; provided, however, that such suspension periods will in no event exceed 90 days in any 12 month period.

(c)Termination of Obligations. The obligations of the Purchaser pursuant to Section 1(a) hereof will cease and terminate, with respect to any Registrable Securities, upon the earlier to occur of (a) such time as such Registrable Securities have been resold, (b) such time as such Registrable Securities are eligible to be sold pursuant to Rule 144 under the Securities Act without any limitation as to volume of sales, and without the Seller needing to comply with any method of sale requirements or notice requirements under Rule 144, or (c) such time as such Registrable Securities will cease to be outstanding following their issuance.

(d)Limitation on Assignment of Registration Rights. The registration rights of each Seller under this Section 1 may not be assigned by a Seller to any other Person unless such a transfer is pursuant to a transfer of Registrable Securities (i) by will or intestate succession, (ii) to a trust upon death, (iii) to an Affiliate of such Seller (provided that there is no change in beneficial ownership), which means with respect to a limited liability company or a limited liability partnership, a fund or entity managed by

the same manager or managing member or general partner or management company or by an entity controlling, controlled by, or under common control with such manager or managing member or general partner or management company or (iv) with the prior written consent of Purchaser. Prior to a permitted transfer of rights under this Section 1 (or, with respect to assignments contemplated by clauses (i) and (ii) of the prior sentence, within a reasonable time following such assignment), Seller must furnish Parent with written notice of the name and address of such transferee and the Registrable Securities with respect to which such registration rights are being assigned and a copy of a duly executed written instrument in form reasonably satisfactory to Purchaser by which such transferee assumes all of the obligations and liabilities of its transferor hereunder and agrees itself to be bound hereby. No transfer of rights under this Section 1 will be permitted if, immediately following such transfer, the offer and sale or other disposition of Registrable Securities by the transferee is not restricted under the Securities Act.

(e)Rule 144. The Shares will be deemed to have been acquired by the Sellers at the Closing as provided in Rule 144(d)(3)(iii), thus starting the applicable Rule 144 holding period. The Shares issued pursuant to the Purchase Agreement will be deemed restricted shares as defined in Rule 144(a)(3) of the Securities Act and will be subject to certain resale restrictions, including a six-month holding period from the Closing, at which time the holders thereof may request the Rule 144 restrictions be removed, and Purchaser agrees to take such action reasonably requested by the holders thereof to authorize the removal of any restricted legends and/or other restrictions on the Purchaser Common Stock, including, if required, an opinion of the Purchaser’s general counsel; provided, however, that in the event Purchaser’s general counsel does not respond and fulfill a request for an opinion from any such holder within five Business Days, such holder may select an alternative counsel reasonably acceptable to Purchaser to provide such opinion, and, in each case, the costs of such opinion will be borne by Purchaser.

2.Seller Indemnification Relating to Registration Statement. From and after the Closing (and with respect to clause (b) below, to the extent permitted by law) and in no way limiting the remedy set forth in Section 5.06 of the Purchase Agreement, the Purchaser will indemnify and hold harmless each Seller, each of its Affiliates and each of their respective Representatives (collectively, the “Seller Indemnitees”) from and against, and will compensate and reimburse each of the Seller Indemnitees for:

(a)any Damages which are suffered or incurred by such Seller Indemnitee (regardless of whether or not such Damages relate to any third-party claim) and which arise from or as a result of, or are connected with the nonfulfillment, nonperformance or other breach of any covenant of the Purchaser contained in Section 1, in any provision of the Purchase Agreement or in any document delivered pursuant hereto or thereto; and

(b)any Damages to which any Seller Indemnitee may become subject under the Securities Act, the Exchange Act, or other federal or state law, insofar as such Damages (or any action in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto; (ii) an omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading; or (iii) any violation or alleged violation by an indemnifying party (or any of its agents or Affiliates) of the Securities Act, the Exchange Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act, or any state securities law.

The Seller Representative will promptly notify the Purchaser if it determines in good faith that (x) any Seller Indemnitee has a bona fide claim for indemnification pursuant to this Section 2 and (y) the

anticipated amount of Damages, to the extent that such amount can be reasonably quantified or estimated. The Purchaser and the Seller Representative will cooperate in good faith to mutually agree on the final amount of Damages to be indemnified hereunder. If no such resolution can be reached during the 30-day period following the receipt of such notice (or such longer period as such parties may subsequently agree), then either party may bring suit to resolve the objection in accordance with Section 4. For the avoidance of doubt, the foregoing will not limit any Seller Indemnitee from commencing any action against the Purchaser under this Section 2 prior to such 30-day notice period. Judgment upon any award rendered by the trial court may be entered in any court having jurisdiction. The Purchaser will pay to each such Seller Indemnitee such amount of Damages as finally determined in accordance with the Purchase Agreement; provided, however, that the indemnity contained in Section 2(b) will not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Purchaser, which consent will not be unreasonably withheld, nor will the Purchaser be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Seller expressly for use in connection with such registration. The maximum aggregate liability of the Purchaser will be limited to either (1) (i) with respect to Section 2(a), the aggregate Deemed Value of the Shares issued or issuable the Purchase Agreement, and (ii) with respect to Section 2(b), the aggregate Deemed Value of the Shares that are actually issued the Purchase Agreement, plus, in each case, (2) the Sellers’ costs and expenses (including reasonable attorneys’ fees) actually incurred to enforce the Sellers’ rights under this Section 2.

3.Purchaser Indemnification Relating to Registration Statement. From and after the Closing, each Seller, severally and not jointly, will indemnify and hold harmless the Purchaser Indemnitees from and against, and will compensate and reimburse each of the Purchaser Indemnitees for any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such Seller expressly for use in connection with any Registration Statement; provided, however, that in no event shall the aggregate amounts payable by any Seller by way of indemnity or contribution under this Section 3 exceed the proceeds from the offering received by such Seller, except in the case of fraud or willful misconduct by such Seller.
