On each Settlement Date, the Shares sold through the relevant Manager for settlement on such date shall be issued and delivered by the Company to such Manager against payment of the net proceeds from the sale of such Shares. Settlement for all such Shares shall be effected by free delivery of the Shares by the Company or its transfer agent to such Manager’s or its designee’s account (provided that such Manager shall have given the Company written notice of such designee prior to the Settlement Date) at The Depository Trust Company or by such other means of delivery as may be mutually agreed upon by the parties hereto, which in all cases shall be freely tradable, transferable, registered shares in good deliverable form, in return for payment in same day funds delivered to the account designated by the Company.

(p) Upon commencement of the offering of the Shares under this Agreement (and upon the recommencement of the offering of the Shares under this Agreement following the termination of a suspension of sales hereunder) and thereafter within two (2) business days of each time that (i) the Registration Statement or the Prospectus is amended or supplemented to include additional financial information, (ii) the Company files an annual report on Form 10-K or quarterly report on Form 10-Q, (iii) there is furnished with the Commission by the Company any document which contains financial information, including any earnings release, (iv) there is filed with the Commission any document (other than an annual report on Form 10-K or quarterly report on Form 10-Q) incorporated by reference into the Prospectus which contains additional or amended financial information or (v) on such other dates as may be reasonably requested by the Managers, Ernst & Young LLP, independent public accountants of the Company, shall deliver to the Managers the comfort letter(s) described in Section 5(f).

(q) To comply with the Due Diligence Protocol attached hereto on Schedule II and any other reasonable due diligence review or call reasonably requested by the Managers.

(r) To reserve and keep available at all times, free of preemptive rights, Shares for the purpose of enabling the Company to satisfy its obligations hereunder.

(s) That it consents to the Managers trading in the Common Stock for each Manager’s own account and for the account of its clients at the same time as sales of the Shares occur pursuant to this Agreement.

(t) That each acceptance by the Company of an offer to purchase the Shares hereunder shall be deemed to be an affirmation to the Managers that the representations and warranties of the Company contained in or made pursuant to this Agreement are true and correct as of the date of such acceptance as though made at and as of such date, and an undertaking that such representations and warranties will be true and correct as of the Time of Sale and the Settlement Date for the Shares relating to such acceptance as though made at and as of each of such dates (except that such representations and warranties shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented relating to such Shares).

(u) Prior to instructing any Manager pursuant to Section 2 hereof to make sales on any given day (or as otherwise agreed between the Company and such Manager), the Company’s board of directors or any authorized committee thereof (i) shall have approved the minimum price and maximum number of Shares to be sold and (ii) shall have provided to the Company an authorizing resolution approving such price and number. The instructions provided to such Manager by the Company, pursuant to Section 2, on such day shall reflect the terms of such authorizing resolution.

(v) Not to sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to sell or otherwise dispose of or agree to dispose of, directly or indirectly, any shares of the Common Stock or securities convertible into or exchangeable or exercisable for the Common Stock or warrants or other rights to purchase the Common Stock or any other securities of the Company that are substantially similar to the Common Stock or permit the registration under the Securities Act of any shares of the Common Stock, except for (i) the registration of the Shares and the sales through the Managers pursuant to this Agreement, (ii) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Prospectus, (iii) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to existing employee benefit plans of the Company or (iv) any shares of Common Stock issued pursuant to any non-employee director stock plan, equity incentive plan, dividend reinvestment plan or stock purchase plan of the Company, during the Delivery Period, without (A) giving the Managers at least three business days’ prior written notice specifying the nature of the proposed sale and the date of such proposed sale and (B) the Managers suspending activity under this program for such period of time as requested by the Company.

(w) The Company will deliver to the Managers (or their agent), on the date of execution of this Agreement, a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation, and the Company undertakes to provide such additional supporting documentation as the Managers may reasonably request in connection with the verification of the foregoing Certification.

7. Covenants of the Managers. The Managers covenant with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Manager that otherwise would not be required to be filed by the Company thereunder, but for the action of the Manager.

8. Indemnity and Contribution. The Company agrees to indemnify and hold harmless each Manager, the directors, officers, employees and agents of each Manager, each person, if any, who controls any Manager within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Manager within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in, or incorporated by reference into, the Registration Statement, the Prospectus, the Prospectus Supplement (including any Interim Prospectus Supplement), the General Disclosure Package, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or any amendment

or supplement thereto, or any Testing-the Waters Communication caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon any information relating to any Manager furnished to the Company in writing by the any Manager expressly for use therein.

(a) Each Manager agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Manager, but only with reference to information relating to such Manager furnished to the Company in writing by such Manager through you expressly for use in the Registration Statement, the Prospectus, the Prospectus Supplement (including any Interim Prospectus Supplement), the General Disclosure Package, or any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or any amendment or supplement thereto.

(b) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing, and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonably incurred fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed in writing to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Managers, in the case of parties indemnified pursuant to Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees

and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(c) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Managers, on the other hand, from the offering of the Shares or (ii) if the allocation provided by Section 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in Section 8(d)(i) above but also the relative fault of the Company, on the one hand, and of the Managers, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Managers, on the other hand, in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company bear to the total commissions received by the Managers. The relative fault of the Company, on the one hand, and the Managers, on the other hand, 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 or by the Managers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(d) The Company and the Managers agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Managers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, 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, no Manager shall be required to contribute any amount in excess of the amount by which the total price at which the Shares sold by it were offered to the public exceeds the amount of

any damages that such Manager has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 remedies provided for 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.

(e) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Manager, the directors, officers, employees and agents of each Manager, any person controlling any Manager or any affiliate of any Manager or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

9. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

10. Termination. The Company shall have the right, by giving written notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time. Any such termination shall be without liability of any party to any other party, except that (i) with respect to any pending sale through the Managers for the Company, the obligations of each of the Company, including, but not limited to, its obligations under Section 4 above, and the Managers pursuant to Sections 3, 4, 5 and 6 shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Section 1, Section 6(i) and Section 8 of this Agreement shall remain in full force and effect notwithstanding such termination.

(a) The Managers shall have the right, by giving written notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) with respect to any pending sale through the Managers for the Company, the obligations of the Company, including, but not limited to, its obligations under Section 4 above, shall remain in full force and effect notwithstanding such termination with respect to and to the extent of the Shares to be sold in such pending sale; and (ii) the provisions of Section 1, Section 6(h)(i) and Section 8 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) This Agreement shall remain in full force and effect until and unless terminated pursuant to Section 10(a) or (b) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement or pursuant to this clause (c) shall in all cases be deemed to provide that Section 1, Section 6(h)(i) and Section 8 of this Agreement shall remain in full force and effect.

(c) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Managers or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Shares, such sale shall settle in accordance with the provisions of Section 4.

11. Entire Agreement. This Agreement represents the entire agreement between the Company and the Managers with respect to the preparation of any Registration Statement, Prospectus Supplement or the Prospectus, the conduct of the offering and the sale and distribution of the Shares.

(a) The Company acknowledges that in connection with the offering of the Shares: (i) the Managers have acted and will act at arm’s length and owes no fiduciary duties to, the Company or any other person, (ii) the Managers owe the Company only those duties and obligations set forth in this Agreement, any contemporaneous written agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Managers may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Managers arising from an alleged breach of fiduciary duty in connection with the sale and distribution of the Shares.

12. Recognition of the U.S. Special Resolution Regimes. In the event that any Manager is a Covered Entity that becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Manager of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(a) In the event that any Manager is a Covered Entity or a BHC Act Affiliate of such Manager becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Manager are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

13. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of a signed counterpart of this Agreement by facsimile or other electronic transmission (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇, or in “.pdf” format) shall constitute valid and sufficient delivery thereof.

14. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

15. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

16. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Managers shall be delivered, mailed or sent to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co.

SCHEDULE II

Due Diligence Protocol

Set forth below are guidelines for use by the Company and the Managers in connection with the Managers’ continuous due diligence efforts in connection with the sale and distribution of the Shares pursuant to the Agreement. For the avoidance of doubt, the Company has agreed that no sales under the Agreement will be requested or made at any time the Company is, or could be deemed to be, in possession of material non-public information with respect to the Company.

On or immediately prior to any date that (1) the registration statement or prospectus is amended or supplemented, (2) any filing is incorporated by reference into the Prospectus (i.e. each 10-Q and 10-K filed during the program) other than a Form 8-K (unless reasonably requested by the Managers if the Managers conclude that the information contained in, or incorporated by reference into, such Form 8-K is material to a holder of Common Stock or to an offering of the Shares) or (3) any of the Shares are delivered to the Managers as principals or pursuant to a block trade, the Company and the Managers will conduct a due diligence call with the appropriate business, financial and legal representatives of the Company.

Every two weeks during the term of the Agreement (rising to each week during the pendency of the COVID-19 crisis, as reasonably determined by the Managers) the Company will make available to the Managers, at a time reasonably acceptable to the Managers, a due diligence call with the appropriate business, financial and legal representatives of the Company. The Company may request the suspension of such diligence calls during any period during which it has determined that it does not intend to request any sales of Shares to be made under the Agreement; provided that if the Company determines to resume sales of Shares under the Agreement, (1) the Company will provide at least 48 hours’ notice to the Managers prior to the resumption of any sales of Shares and (2) the Company will make available to the Managers, at a time reasonably acceptable to the Managers, a due diligence call with the appropriate business, financial and legal representatives of the Company. Any due diligence call pursuant to the foregoing paragraph 2 shall be conducted as an update from the previous due diligence call, focused principally on changes and developments since the prior due diligence call.

In the event that the Company requests the Managers to sell on any one Trading Day an amount of Shares that would be equal to or greater than 20% of the average daily trading volume (calculated based on the most recent three completed Trading Days) of the Company’s common stock, the Company will make available to the Managers, at a time reasonably acceptable to the Managers, a due diligence call with the appropriate business, financial, accounting and legal representatives of the Company and the Company shall provide the certificate referred to in Section 5(b) of the Agreement.

The foregoing is an expression of current intent only, and shall not in any manner limit the Managers’ rights under the Agreement, including the Managers’ right to require such additional reasonable due diligence procedures as the Managers may reasonably request pursuant to the Agreement.
