The Company is duly qualified and is authorized to do business and is in good standing as a foreign corporation in all jurisdictions in which the nature of its activities and of its properties (both owned and leased) makes such qualification necessary, except for those jurisdictions in which failure to do so would not have a material adverse effect on the Company or its business.

b. Authorization; Binding Obligations. All corporate action on the part of the Company, its officers, directors and shareholders necessary for the authorization of this Agreement and the Shares, the performance of all obligations of the Company hereunder at the Closing, and the sale, issuance and delivery of the Shares pursuant hereto has been taken or will be taken prior to the Closing.

which it is bound, (ii) conflict with or result in a breach of or constitute a default under any provision of the certificate of incorporation or bylaws (or other charter documents) of the Company, or (iii) violate or result in a breach of or constitute a default under any judgment, order, decree, rule or regulation of any court or governmental agency to which the Company is subject.

d. SEC Reports; Financial Statements. The Company has filed all SEC Reports required to be filed by the Company under the Securities Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof, for the two years preceding the date hereof (or such shorter period as the Company was required by law or regulation to file such material). The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the U.S. Securities and Exchange Commission (the “Commission”) with respect thereto as in effect at the time of filing. Such financial statements have been prepared in accordance with United States generally accepted accounting principles applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material respects the financial position of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments.

e. Capitalization. Except as set forth on Schedule 2.e., the authorized capital stock of the Company and the issued and outstanding securities of the Company are as disclosed as of the Effective Date in the SEC Reports.

f. Absence of Litigation. Neither the Company nor any of its directors is engaged in any litigation, administrative, mediation or arbitration proceedings or other proceedings or hearings before any statutory or governmental body, department, board or agency and is not the subject of any investigation, inquiry or enforcement proceedings by any governmental, administrative or regulatory body. Except as set forth on Schedule 2.f., no such proceedings, investigation or inquiry are pending or, to the Company’s knowledge, threatened against the Company, and, to the Company’s knowledge, there are no circumstances likely to give rise to any such proceedings.

The Company has not received a notice (written or otherwise) that any of, the Intellectual Property Rights has expired, terminated or been abandoned, or is expected to expire or terminate or be abandoned, within two (2) years from the date of this Agreement. To the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is no existing infringement by another Person of any of the Intellectual Property Rights.

h. Valid Issuance. The Shares issued hereunder will be duly and validly issued, fully paid and non-assessable and will be free of restrictions on transfer other than restrictions on transfer under this Agreement and under applicable state and federal securities laws.

3. Invesco Representations and Warranties. Invesco represents and warrants to the Company that:

a. Requisite Power and Authority. Invesco has all necessary power and authority under all applicable provisions of law to execute and deliver this Agreement and to carry out its provisions. All action on Invesco’s part required for the lawful execution and delivery of this Agreement has been or will be taken prior to the Closing.

b. Own Account. Invesco is acquiring the Shares for investment for Invesco’s managed clients’ accounts, and not with a view to, or for resale in connection with, any distribution thereof in the United States, and Invesco has no present intention of selling or distributing any Shares in the United States. Invesco understands that the Shares have not been registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment as expressed herein. For the avoidance of doubt, this Section 3(b) is not intended to restrict Invesco’s ability to transfer the securities outside the United States pursuant to Regulation S promulgated under the Securities Act. It is the parties’ understanding that the provisions of the Securities Act will not ordinarily restrict Invesco’s ability to transfer the Shares outside the United States pursuant to Regulation S promulgated under the Securities Act.

c. Access to Data. Invesco has had an opportunity to discuss the Company’s business, management and financial affairs with the Company’s management and to obtain any additional information which Invesco has deemed necessary or appropriate for deciding whether or not to purchase the Shares, including an opportunity to receive, review and understand the information regarding the Company’s financial statements, capitalization and other business information contained in the SEC Reports and the Company’s Registration Statement on Form S-4 (File No. 333-217364) filed with the Commission on July 3, 2017 as Invesco deems prudent. Invesco acknowledges that no representations or warranties, oral or written, have been made by the Company or any agent thereof except as set forth in this Agreement.

d. No Fairness Determination. Invesco is aware that no federal, state or other agency has made any finding or determination as to the fairness of the investment, nor made any recommendation or endorsement of the Shares.

e. Knowledge And Experience. Invesco has such knowledge and experience in financial and business matters, including investments in other start-up companies, that such entity or individual is capable of evaluating the merits and risks of the investment in the Shares and it is able to bear the economic risk of such investment. Invesco is an “accredited” investor as that term is defined under Regulation D promulgated under the Securities Act, and as set forth on Schedule I attached hereto. Further, Invesco has such knowledge and experience in financial and business matters that such individual is capable of utilizing the information made available in connection with the offering of the Shares, of evaluating the merits and risks of an

investment in the Shares and of making an informed investment decision with respect to the Shares. Neither Invesco, nor any person or entity with whom Invesco will share beneficial ownership of the Shares, is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act.

f. General Solicitation. Invesco is not, to Invesco’s knowledge, purchasing the Shares as a result of any advertisement, article, notice or other communication regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement.

g. Residence. Invesco’s principal place of business or residence is and its investment decisions are made in the jurisdiction identified in the address or other jurisdiction set forth on the signature page.

4. Restrictions on Transfer.

THIS SECURITY MAY BE SUBJECT TO ADDITIONAL RESTRICTIONS PURSUANT TO EXEMPTIONS IN THE VARIOUS JURISDICTIONS WHERE THEY ARE BEING SOLD.

b. Certificates evidencing the Shares shall not contain any legend (including the legend set forth in Section 4(a) above), (i) while a registration statement (including the Registration Statement (as defined below)) covering the resale of such security is effective under the Securities Act, (ii) following any sale of such Shares pursuant to Rule 144, (iii) if 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 as to such Shares and without volume or manner-of-sale restrictions, or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission).

The Company shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as possible after the filing thereof, but in any event (x) no later than the sixtieth (60th) day following the filing of the Registration Statement in the event of “limited review” by the Commission, or (y) in the event of a “review” by the Commission, the ninetieth (90th) day following the filing of the Registration Statement, and shall use its commercially reasonable efforts to keep such Registration Statement continuously effective under the Securities Act during the entire Effectiveness Period.

b. Notwithstanding anything in this Section to the contrary, the Company may, on no more than two occasions during any 12-month period, delay or suspend the effectiveness of the Registration Statement for up to 30 days on each occasion (a “Delay Period”) if the board of directors of the Company determines in good faith that (i) effectiveness of the Registration Statement must be suspended in accordance with the rules and regulations under the Securities Act or that (ii) the disclosure of material non-public information (“Pending Developments”) at such time would be detrimental to the Company and its subsidiaries, taken as a whole. Notwithstanding the foregoing, the Company shall use its reasonable best efforts to ensure that the Registration Statement is declared effective and its permitted use is resumed following a Delay Period as promptly as practicable.

c. If at any time the Company proposes to file a Registration Statement (other than to file a shelf registration that is not in connection with a particular offering), or the Company proposes to sell Company Common Stock in an underwritten offering for cash (excluding the Excluded Registration Statements and excluding an offering relating solely to an employee benefit plan or an offering relating to a transaction on Form S-4) (a “Piggyback Registration Statement”), the Company shall give prompt written notice (the “Piggyback Notice”) to all Holders that hold Registrable Securities (collectively, the “Piggyback Eligible Holders”) of the Company’s intention to file a Piggyback Registration Statement reasonably in advance of (and in any event at least ten (10) Business Days before) the anticipated filing date of such Piggyback Registration Statement.

The Company shall use its commercially reasonable efforts to include in each such Piggyback Registration such Registrable Securities for which the Company has received written requests (each, a “Piggyback Request”) from Piggyback Eligible Holders within five (5) Business Days after giving the Piggyback Notice. The Company shall use its commercially reasonable efforts to effect the registration under the Securities Act of all Registrable Securities which the Company has been so requested to register pursuant to the Piggyback Requests, to the extent required to permit the disposition of the Registrable Securities so requested to be registered.

d. All fees and expenses incident to the performance of or compliance with this Section by the Company shall be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement.

e. Except for registration rights granted on or prior to the Merger Effective Date, the Company has not entered into and, unless agreed in writing by each Holder on or after the date of this Agreement, will not enter into, any agreement or arrangement that (i) is inconsistent with the rights granted to the Holders with respect to Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof in any material respect or (ii) other than as set forth in this Agreement, would allow any holder of Company Common Stock or other securities of the Company to include such securities in any Registration Statement filed by the Company on a basis that is more favorable in any material respect to the rights granted to the Holders hereunder including granting registration rights that would have priority over the Registrable Securities with respect to the inclusion of such securities in any registration.
