The Company is not aware of any material weaknesses in its internal control over financial reporting. Since the date of the latest audited financial statements of the Company included in the Prospectus and Pricing Disclosure Package, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting (other than as set forth in the Prospectus and Pricing Disclosure Package). The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company and the Subsidiaries is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of a date within 90 days prior to the filing date of the Form 10-K for the fiscal year most recently ended (such date, the “Evaluation Date”). The Company presented in its Form 10-K for the fiscal year most recently ended the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Securities Act) or, to the Company’s knowledge, in other factors that could significantly adversely affect the Company’s internal controls. To the knowledge of the Company, the Company’s “internal controls over financial reporting” and “disclosure controls and procedures” are effective.

(dd) There is and has been no failure on the part of the Company or, to the knowledge of the Company, any of the Company’s directors or officers, in their capacities as such, to comply with any applicable provisions of the Sarbanes-Oxley Act and the rules and regulations promulgated thereunder.

(d) The Underwriters shall have received on and as of the Closing Date or the Option Closing Date, as the case may be, a certificate of the Chief Executive Officer and the Chief Financial Officer of the Company, satisfactory to the Underwriters, to the effect that (1) the representations and warranties of the Company contained herein are true and correct on and as of the Closing Date or the Option Closing Date, as the case may be, as if made on and as of the Closing Date or the Option Closing Date, as the case may be, and that the Company has complied with all agreements and all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date or the Option Closing Date, as the case may be, (2) none of the situations set forth in clause (i) or (ii) of Section 7(c) shall have occurred and (3) no stop order suspending the effectiveness of the Registration Statement has been issued and to the knowledge of the Company, no proceedings for that purpose have been instituted or are pending or contemplated by the Commission.

(h) On the Closing Date and each Option Closing Date, as the case may be, the Underwriters shall have received from BDO a letter, dated the Closing Date and each such Option Closing Date, as the case may be, to the effect that they reaffirm the statements made in the letter or letters furnished pursuant to Section 7(g), except that the specified date referred to shall be a date not more than three business days prior to the Closing Date or such Option Closing Date, as the case may be.

(i) On the Closing Date or the Option Closing Date, as the case may be, Duane Morris LLP, counsel for the Underwriters, shall have furnished to the Underwriters their favorable opinion dated the Closing Date or the Option Closing Date, as the case may be, with respect to the due authorization and valid issuance of the Shares, the Registration Statement, the Prospectus and other related matters as the Underwriters may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters.

If any condition specified in this Section 7 shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated, subject to the provisions of Section 10, by the Representatives by notice to the Company at any time at or prior to the Closing Date or Option Closing Date, as the case may be, and such termination shall be without liability of any party to any other party, except as provided in Section 10.

8. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Underwriter and each of their directors, officers, employees, agents and representatives and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any post-effective amendment thereof, any Preliminary Prospectus, Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement, as originally filed or any amendment thereof, the Registration Statement, or any post-effective amendment thereof, any Preliminary Prospectus, Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof or any Issuer Free Writing Prospectus in reliance upon and in strict conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter is the information described as such in Section 8(b) of this Agreement.

(b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless the Company and each of its directors, officers, employees, agents and representatives, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any post-effective amendment thereof, or any Preliminary Prospectus, Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, any Issuer Free Writing Prospectus, to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement made therein in reliance upon and in strict conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of any Underwriter: (i) the selling concession figure set forth under the caption “Underwriting—Underwriting Discount and Expenses” in Pricing Disclosure Package and (ii) the information provided under the captions “Underwriting—Passive Market Making,” “Underwriting—Price Stabilization, Short Positions and Penalty Bids” and “Underwriting—Electronic Distribution” in Pricing Disclosure Package.

(c) Promptly after receipt by an indemnified party under Section 8(a) or 8(b) of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section, notify each party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 8). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and jointly with any other indemnifying party similarly notified, to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnified party). Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, which counsel, in the event of indemnified parties under Section 8(a), shall be selected by the Representatives. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand and the Underwriter, on the other hand, from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Shares shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Underwriters on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount pursuant to this Section 8(d) in excess of the sum of (i) any structuring fees paid to it hereunder and (ii) the underwriting discounts and commissions applicable to the Shares underwritten by it and distributed to the public.

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. The Underwriters’ obligations in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

The obligations of the parties to this Agreement contained in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

9. Increase in Underwriters’ Commitments. If any Underwriter or Underwriters default in its or their obligations to purchase Shares hereunder on the Closing Date or any Option Closing Date and the aggregate number of Shares that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date or Option Closing Date, as the case may be, the Representatives may make arrangements satisfactory to the Company for the purchase of such Shares by other persons, including any of the other Underwriters, but if no such arrangements are made within 36 hours after such default, this Agreement will terminate, subject to the provisions of Section 10, without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10. Nothing herein will relieve a defaulting Underwriter from liability for its default.

In the event of any such default, which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Date or the relevant Option Closing Date, as the case may be, for a period not exceeding seven (7) days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 9.

10. Survival. The respective indemnities, agreements, representations, warranties and other statements of the Company or any of its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter or the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares. If this Agreement is terminated pursuant to Section 7 or 9 or if for any reason the purchase of any of the Shares by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 6, the respective obligations of the Company and the Underwriters pursuant to Section 8 and the provisions of Sections 10, 11 and 14 shall remain in effect.

11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Company and the Underwriters, the officers and directors of the Company referred to herein, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Shares from any Underwriter shall be deemed to be a successor or assign by reason merely of such purchase.

12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given upon receipt thereof by the recipient if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be given to the Representatives, The Benchmark Company, LLC, 150 East 58th Street, 17th Floor, New York, New York 10155, Attention: Managing Director, Telephone: 212-312-6700, Email: prospectus@benchmarkcompany.com, and ThinkEquity, 17 State Street, 22nd Floor, New York, NY 10004, Attention: Eric Lord, Email: notices@think-equity.com,, with a copy to Duane Morris LLP, 1540 Broadway, New York, NY 10036, Attention: James T.

14. Governing Law; Construction. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

15. Submission to Jurisdiction. The parties hereby submit to the jurisdiction of and venue in the federal courts located in the City of New York, New York in connection with any dispute related to this Agreement, any transaction contemplated hereby, or any other matter contemplated hereby.

16. Parties At Interest. The Agreement herein set forth has been and is made solely for the benefit of the Underwriters, the Company and to the extent provided in Section 8 hereof the controlling Persons, directors and officers referred to in such Section, and their respective successors, assigns, heirs, pursuant representatives and executors and administrators. No other Person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

17. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the purchase price of the Shares and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, (b) in connection therewith and with the process leading to such transaction each Underwriter is and has been acting solely as a principal and not the agent or fiduciary of the Company, or its stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of each of the Company, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

18. Research Analyst Independence. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriter’s investment banking divisions.

19. Tax Disclosure. Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

20. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof

21. RIGHT TO TRIAL BY JURY. Each of the Company and the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

EXHIBIT A

FORM OF OPINION OF ALSTON & BIRD LLP

The Company and its Subsidiaries are corporations validly existing in good standing under the laws of the State of Delaware.

The Company and its Subsidiaries are duly qualified to do business as a foreign corporation in each jurisdiction in which the Company and its Subsidiaries own any material property or conduct any material business or in which the failure to be qualified as a foreign corporation would have a Material Adverse Effect.

The Company has the corporate power to own, lease and operate its properties and conduct its business as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus.

The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Underwriting Agreement has been duly authorized by all necessary corporate action on the part of the Company.

The Shares, when issued and delivered by the Company in accordance with the terms of the Underwriting Agreement against payment of the consideration set forth therein, will be duly authorized, validly issued, fully paid and nonassessable.

The issuance and sale of the Shares by the Company is not subject to preemptive or other similar rights arising under the Amended & Restated Certificate of Incorporation (the “Certificate of Incorporation”) or Second Amended & Restated Bylaws (the “Bylaws”) of the Company or under any agreement to which the Company is a party.

The execution, delivery and performance of the Underwriting Agreement by the Company and the transactions contemplated thereby do not conflict with, or result in any breach of, or constitute a default under (nor constitute an event that with notice, lapse of time or both would constitute a breach of or default under), (i) the Certificate of Incorporation or Bylaws of the Company, (ii) any agreement to which the Company is a party or (iii) any applicable law or, to our knowledge, any decree, judgment or order applicable to the Company (other than state and foreign securities or blue sky laws, as to which we express no opinion), except in the case of clauses (ii) and (iii) for such conflicts, breaches or defaults, which individually or in the aggregate could not be reasonably expected to have a Material Adverse Effect.

No approval, notice to, consent, authorization or order of any court or governmental agency, body or official is required for, the execution and delivery by the Company of the Underwriting Agreement or to issue and sell the Shares, other than as may be required under the Securities Act, the Exchange Act, blue sky laws of any state, the rules of listing on the Nasdaq Capital Market or the rules and regulations of the Financial Industry Regulatory Authority.

To our knowledge, except as described in the Registration Statement, Pricing Disclosure Package and the Prospectus, there are no persons with registration rights or other similar rights to have any securities of the Company registered pursuant to the Registration Statement.

10.

The Registration Statement, as of the date it became effective under the Securities Act and as of the date hereof, the Pricing Disclosure Package, as of its date and the date hereof, and the Prospectus, as of its date and the date hereof (in each case other than the financial statements and schedules and other financial data included or incorporated by reference therein, as to which we express no opinion), complied as to form in all material respects with the requirements of the Securities Act and the rules and regulations of the Commission promulgated thereunder.

11.

The Registration Statement has become effective under the Securities Act and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or threatened by the Commission. The Prospectus has been filed in the manner and within the time period required by Rule 424(b) under the Securities Act.

12.

The Company is not an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended, (the “1940 Act”) or a company “controlled” by an “investment company” within the meaning of the 1940 Act.

13.

The statements under the captions “Description of Series A Preferred Stock,” and “Material U.S. Federal Income Tax Considerations” in the Preliminary Prospectus, Pricing Disclosure Package and the Prospectus insofar as such statements purport to summarize certain provisions of documents and legal matters referred to therein and reviewed by us as described above, fairly summarize such provisions and legal matters in all material respects, subject to the qualifications and assumptions stated therein.

In addition, we participated in conferences with officers and other representatives of the Company, representatives of independent public accountants for the Company at which the contents of the Registration Statement, Pricing Disclosure Package and the Prospectus (including any of the Company’s reports that have been filed with the Commission and are incorporated by reference in the Registration Statement (the “Incorporated Documents”) and related matters were discussed, and although we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, Pricing Disclosure Package and the Prospectus (except as and to the extent set forth in Paragraph 12 above) and have not made any independent check or verification thereof, during the course of such participation, nothing has come to our attention that leads us to believe (i) that the Registration Statement, as of its most recent effective date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Pricing Disclosure Package (including the Incorporated Documents), as of 5:00 p.m., New York city time, on November 25, 2019 (which you have informed us is a time prior to the time of the first sale of the Firm Shares by any Underwriter), insofar as relating to the offering of the Shares, contained an untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (iii) that the Prospectus (including the Incorporated Documents), as of its date and as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that we express no belief with respect to the financial statements, financial schedules and other financial data included or incorporated by reference in, or excluded from, the Registration Statement, Pricing Disclosure Package or the Prospectus).
