The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement under the Securities Act of 1933, as amended (the “1933 Act”), on Form S-3 (File No. 333-238896), in respect of the Company’s Shares and other securities, not declared effective by the Commission earlier than three years prior to the date hereof; such registration statement, and any post-effective amendment thereto, has become effective; and no stop order suspending the effectiveness of such registration statement or any part thereof has been issued and no proceeding for that purpose has been initiated or, to the knowledge of the Company, threatened by the Commission (the base prospectus filed as part of such registration statement, in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement, is hereinafter called the “Basic Prospectus”; the various parts of such registration statement, including all exhibits thereto and any prospectus supplement relating to the Shares that is filed with the Commission and deemed by virtue of Rule 430B to be part of such registration statement, each as amended at the time such part of the registration statement became effective, including any post-effective amendments, thereto, are hereinafter collectively called the “Registration Statement”; the prospectus supplement specifically relating to the Shares prepared and filed with the Commission pursuant to Rule 424(b) under the 1933 Act is hereinafter called the “Prospectus Supplement”; the Basic Prospectus, as amended and supplemented by the Prospectus Supplement, is hereinafter called the “Prospectus”; any reference herein to the Basic Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act; any reference to any amendment or supplement to the Basic Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include any post-effective amendment to the Registration Statement, any prospectus supplement relating to the Shares filed with the Commission pursuant to Rule 424(b) under the 1933 Act and any documents filed under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”), and incorporated therein, in each case after the date of the Basic Prospectus, the Prospectus Supplement or the Prospectus, as the case may be; any reference to any amendment to the Registration Statement shall be deemed to refer to and include any annual report of the Company filed pursuant to Section 13(a) or 15(d) of the 1934 Act after the effective date of the Registration Statement that is incorporated by reference in the Registration Statement; and any “issuer free writing prospectus” as defined in Rule 433 under the 1933 Act relating to the Shares is hereinafter called an “Issuer Free Writing Prospectus”).

No order preventing or suspending the use of the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus has been issued by the Commission, and the Basic Prospectus and the Prospectus Supplement, at the time of filing thereof, conformed in all material respects to the requirements of the 1933 Act and the rules and regulations of the Commission thereunder and did not contain an untrue statement of a material fact or omit 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.

For the purposes of this Agreement, the “Applicable Time” means, with respect to any Shares, the time of sale of such Shares pursuant to this Agreement; the Prospectus and the applicable Issuer Free Writing Prospectus(es) issued at or prior to such Applicable Time, taken together (collectively, and, with respect to any Shares, together with the public offering price of such Shares, the “General Disclosure Package”) as of each Applicable Time and each Settlement Date, will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and each applicable Issuer Free Writing Prospectus will not conflict with the information contained in the Registration Statement, the Prospectus Supplement or the Prospectus and each such Issuer Free Writing Prospectus, as supplemented by and taken together with the General Disclosure Package as of such Applicable Time, will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(b) Incorporation of Documents by Reference. The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, when they became effective or were filed with the Commission, as the case may be, complied in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations, and, when read together with the other information in the Prospectus, (a) at the time the Registration Statement became effective, (b) at the time the Prospectus was issued and (c) on the date of this Agreement, did not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(f) No Material Adverse Change. Except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, subsequent to the respective dates as of which information is given in the Registration Statement, the General Disclosure Package and the Prospectus: (i) there has been no material adverse change, or any development that could reasonably be expected to result in a material adverse change, in the condition, financial or otherwise, or in the earnings, business, properties, operations, assets, liabilities or prospects, whether or not arising from transactions in the ordinary course of business, of the Company (any such change being referred to herein as a “Material Adverse Change”); (ii) the Company has not incurred any material liability or obligation, indirect, direct or contingent, including without limitation any losses or interference with its business from fire, explosion, flood, earthquakes, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute or court or governmental action, order or decree, that are material, individually or in the aggregate, to the Company or has entered into any transactions not in the ordinary course of business that are material, individually or in the aggregate, to the Company; and (iii) there has not been any material decrease in the share capital or any material increase in any short-term or long-term indebtedness of the Company and there has been no dividend or distribution of any kind declared, paid or made by the Company or any repurchase or redemption by the Company of any class of share capital.

Section 2. Sale and Delivery of Shares.

(a) Subject to the terms and conditions set forth herein, the Company agrees to issue and sell exclusively through an Agent acting as sales agent or directly to an Agent acting as principal from time to time (the “Designated Agent”), and the Designated Agent agrees to use its commercially reasonable efforts to sell as sales agent for the Company, the Shares. Sales of the Shares, if any, through the Designated Agent acting as sales agent or directly to the Designated Agent acting as principal will be made by means of ordinary brokers’ transactions on the Nasdaq, in negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. Anything to the contrary notwithstanding in this Agreement, without the Company’s prior written consent, the Designated Agent may not place any shares by any method other than transactions that are deemed to be “at the market offerings” as defined in Rule 415(a)(4) under the 1933 Act, including sales made directly on the Nasdaq or any other existing trading market for the Shares. The Designated Agent shall effect any sales of Shares in accordance with applicable state and federal rules and regulations and the rules of Nasdaq and otherwise in accordance with the instructions to sell shares delivered pursuant to Section 2(b). Nothing contained herein restricts, nor may be deemed to restrict, the Company from undertaking another offering of its securities, including pursuant to separate registrations under the 1933 Act (or any exemption from such registration), or another offering under the Registration Statement, provided the Company complies with Section 3(p).

(b) Subject to instructions to sell Shares delivered pursuant to this Section 2(b) or the applicable Terms Agreement, the Shares are to be sold on a daily basis or otherwise as shall be agreed to by the Company and the Designated Agent on that trading day (other than a day on which the Nasdaq is scheduled to close prior to its regular weekday closing time, each, a “Trading Day”) that the Company has satisfied its obligations under Section 7 of this Agreement and that the Company has instructed the Designated Agent to make such sales. For the avoidance of doubt, the foregoing limitation shall not apply to sales solely to employees or security holders of the Company or its subsidiaries, or to a trustee or other person acquiring such securities for the accounts of such persons in which the Designated Agent is acting for the Company in a capacity other than as Agent under this Agreement. On any Trading Day, the Company may instruct the Designated Agent by telephone (confirmed promptly by telecopy or email, which confirmation will be promptly acknowledged by the Designated Agent) as to the maximum aggregate dollar value of Shares or number of Shares to be sold by the Designated Agent on such day (in any event not in excess of the number available for issuance under the Prospectus and the currently effective Registration Statement), the minimum price per Share at which such Shares may be sold and in accordance with such other terms specified by the Company in connection with such instruction. For purposes of this Section 2, the notice parties for each of the Company and the Agents are set forth on Schedule 1. Subject to the terms and conditions hereof, the Designated Agent shall use its commercially reasonable efforts to sell as sales agent all of the Shares so designated by the Company and in the manner and on the terms so designated by the Company. The Company and the Designated Agent each acknowledge and agree that (A) there can be no assurance that the Designated Agent will be successful in selling the Shares, (B) the Designated Agent will incur no liability or obligation to the Company or any other person or entity if they do not sell Shares for any reason other than a failure by the Designated Agent to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Shares as required by this Agreement, and (C) the Designated Agent shall be under no obligation to purchase Shares on a principal basis except as otherwise specifically agreed by each of the Designated Agent and the Company pursuant to this Agreement and the applicable Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

(c) Notwithstanding the foregoing, the Company shall not authorize the issuance and sale of, and the Designated Agent as sales agent shall not sell, any Shares (i) at a price lower than the minimum price therefor authorized from time to time, or (ii) in a number in excess of the number or maximum aggregate dollar value of Shares authorized from time to time to be issued and sold under this Agreement, in each case, by the Company’s board of directors, or a duly authorized committee thereof, and notified to the Designated Agent in writing. In addition, the Company may, upon notice to the Designated Agent, suspend the offering of the Shares or the Designated Agent may, upon notice to the Company, suspend the offering of the Shares with respect to which the Designated Agent is acting as sales agent for any reason and at any time; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Shares sold hereunder prior to the giving of such notice. Any notice given pursuant to the preceding sentence may be given by telephone (confirmed promptly by telecopy or email, which confirmation will be promptly acknowledged).

(d) The gross sales price per share of any Shares sold pursuant to this Agreement by the Designated Agent acting as sales agent of the Company shall be the market price prevailing at the time of sale for the Company’s Shares sold by the Designated Agent on the Nasdaq or otherwise, at prices relating to prevailing market prices or at negotiated prices. The compensation payable to the Designated Agent for sales of Shares with respect to which the Designated Agent acts as sales agent shall be up to 3.0% of the gross sales price of the Shares for amounts of Shares sold pursuant to this Agreement. The Company may sell Shares to the Designated Agent, acting as principal, at a price agreed upon with the Designated Agent at the relevant Applicable Time and pursuant to a separate Terms Agreement. The remaining proceeds, after further deduction for any transaction fees imposed by any governmental, regulatory or self-regulatory organization in respect of such sales, shall constitute the net proceeds to the Company for such Shares (the “Net Proceeds”). The Designated Agent shall notify the Company as promptly as practicable if any deduction referenced in the preceding sentence will be required.

(e) If acting as a sales agent hereunder, the Designated Agent shall provide written confirmation to the Company following the close of trading on the Nasdaq, each day in which Shares are sold under this Agreement setting forth the number of Shares sold on such day, the aggregate gross sales proceeds of the Shares, the Net Proceeds to the Company and the compensation payable by the Company to such Designated Agent with respect to such sales.

(f) Under no circumstances shall the aggregate offering price or number, as the case may be, of Shares sold pursuant to this Agreement and any Terms Agreement exceed the aggregate offering price or number, as the case may be, of Shares (i) set forth in the preamble paragraph of this Agreement, (ii) available for issuance under the Prospectus and the then currently effective Registration Statement or (iii) authorized from time to time to be issued and sold under this Agreement or any Terms Agreement by the Company’s board of directors, or a duly authorized committee thereof, and notified to the Designated Agent in writing. In addition, under no circumstances shall any Shares with respect to which the Designated Agent acts as sales agent be sold at a price lower than the minimum price therefor authorized from time to time by the Company’s board of directors, or a duly authorized committee thereof, and notified to the Designated Agent in writing.

(g) Settlement for sales of Shares pursuant to this Section 2 will occur on the second business day that is also a Trading Day following the trade date on which such sales are made, unless another date shall be agreed to by the Company and the Designated Agent (each such day, a “Settlement Date”). On each Settlement Date, the Shares sold through the Designated Agent for settlement on such date shall be delivered by the Company to the Designated Agent against payment of the Net Proceeds from the sale of such Shares. Settlement for all Shares shall be effected by book-entry delivery of Shares to the Designated Agent’s account at The Depository Trust Company against payments by the Designated Agent of the Net Proceeds from the sale of such Shares in same day funds delivered to an account designated by the Company. If the Company shall default on its obligation to deliver Shares on any Settlement Date, the Company shall (i) indemnify and hold the Designated Agent harmless against any loss, claim or damage arising from or as a result of such default by the Company and (ii) pay the Designated Agent any commission to which it would otherwise be entitled absent such default.

(h) Notwithstanding any other provision of this Agreement, the Company and the Agents agree that no sales of Shares shall take place, and the Company shall not request the sale of any Shares that would be sold, and the Agents shall not be obligated to sell, during any period in which the Company is, or could be deemed to be, in possession of material non-public information.

(i) At each Applicable Time, Settlement Date, Registration Statement Amendment Date and each Company Periodic Report Date, the Company shall be deemed to have affirmed each representation and warranty contained in this Agreement. Any obligation of the Agents to use their commercially reasonable efforts to sell the Shares on behalf of the Company as sales agent shall be subject to the continuing accuracy of the representations and warranties of the Company herein, to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 7 of this Agreement.

(j) The Company agrees that any offer to sell Shares, any solicitation of an offer to buy Shares, or any sales of Shares shall only be effected by or through an Agent, and only a single Agent, on any single given day and the Company shall in no event request that more than one Agent offer or sell Shares on the same day; provided, however, that (i) the foregoing limitation shall not apply to (A) exercise of any option, warrant, right or any conversion privilege set forth in the instruction governing such securities, (B) sales solely to employees, directors or security holders of the Company or its subsidiaries, or to a trustee or other person acquiring such securities for the accounts of such person and (ii) such limitation shall not apply (A) on any day during which no sales are made pursuant to this Agreement or (B) during a period in which the Company has notified the Agents that it will not sell Shares under this Agreement and (1) no instructions to a Designated Agent to sell Shares are pending or (2) after instructions to a Designated Agent to sell Shares have been withdrawn.

In each Annual Report on Form 10-K or Quarterly Report on Form 10-Q filed by the Company in respect of any quarter in which sales of Shares were made by or through an Agent under this Agreement or any Terms Agreement (each date on which any such document is filed, and any date on which an amendment to any such document is filed, a “Company Periodic Report Date”), the Company shall set forth with regard to such quarter the number of Shares sold through the Agents under this Agreement or any Terms Agreement and the Net Proceeds received by the Company with respect to sales of Shares pursuant to this Agreement or any Terms Agreement.

(j) Upon commencement of the offering of Shares under this Agreement and each time the Shares are delivered to an Agent as principal on a Settlement Date and promptly after each (i) date the Registration Statement or the Prospectus shall be amended or supplemented (other than (1) by an amendment or supplement providing solely for the determination of the terms of the Shares, (2) in connection with the filing of a prospectus supplement that contains solely the information set forth in Section 3(i), (3) in connection with the filing of any current reports on Form 8-K (other than any current reports on Form 8-K which contain financial statements, supporting schedules or other financial data, including any current report on Form 8-K under Item 2.02 of such form that is considered “filed” under the ▇▇▇▇ ▇▇▇) or (4) by a prospectus supplement relating to the offering of other securities (including, without limitation, other Shares of the Company)) (each such date, a “Registration Statement Amendment Date”) and, (ii) Company Periodic Report Date, the Company will furnish or cause to be furnished forthwith to the Agents a certificate dated the date of effectiveness of such amendment or the date of filing with the Commission of such supplement or other document, as the case may be, in a form reasonably satisfactory to the Agents to the effect that the statements contained in the certificate referred to in Section 7(f)(ii) of this Agreement which were last furnished to the Agents are true and correct at the time of such amendment, supplement or filing, as the case may be, as though made at and as of such time (except that such statements shall be deemed to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented to such time) or, in lieu of such certificate, a certificate of the same tenor as the certificate referred to in said Section 7(f)(ii), but modified as necessary to relate to the Registration Statement and the Prospectus as amended and supplemented, or to the document incorporated by reference into the Prospectus, to the time of delivery of such certificate. As used in this paragraph, to the extent there shall be an Applicable Time on or following the date referred to in clause (i) or (ii) above, promptly shall be deemed to be on or prior to the next succeeding Applicable Time. Notwithstanding the foregoing, the Company shall not be required to deliver any such certificate at any time there is no instruction to sell Shares delivered pursuant to Section 2(b) then in effect; provided, however, that such a certificate shall then be required to be delivered to the Agents prior to any further sales of Shares under this Agreement covering the period which would most recently have been required but for this sentence.

(k) Upon commencement of the offering of Shares under this Agreement and each time the Shares are delivered to an Agent as principal on a Settlement Date, and promptly after each (i) Registration Statement Amendment Date and (ii) Company Periodic Report Date, the Company will furnish or cause to be furnished to the Agents the written opinion of each Company counsel and written negative assurance statement of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, Professional Corporation (“WSGR”), or other counsel reasonably satisfactory to the Agents, dated the date of effectiveness of such amendment or the date of filing with the Commission of such supplement or other document, as the case may be, in a form and substance reasonably satisfactory to the Agents and their counsel, of the same tenor as the opinions and letters referred to in Section 7(c) of this Agreement, but modified as necessary to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented, or to the document incorporated by reference into the Prospectus, to the time of delivery of such opinion and letter or, in lieu of such opinion and letter, counsel last furnishing such letter to the Agents shall furnish such Agents with a letter substantially to the effect that the Agents may rely on such last opinion and letter to the same extent as though each were dated the date of such letter authorizing reliance (except that statements in such last letter shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such letter authorizing reliance). As used in this paragraph, to the extent there shall be an Applicable Time on or following the date referred to in clause (i) or (ii) above, promptly shall be deemed to be on or prior to the next succeeding Applicable Time. Notwithstanding the foregoing, (i) the Company shall not be required to furnish or cause to be furnished any such opinion or statement at any time there are no instructions to sell Shares delivered pursuant to Section 2(b) or a Terms Agreement then in effect; provided, however, that such an opinion or letter shall then be required to be furnished to the Agents prior to any further sales of Shares under this Agreement covering the period which would most recently have been required but for this sentence, and (ii) following the Agents being furnished with the first opinion(s) pursuant to this Section 3(k), subsequent opinions or letters furnished pursuant to this Section 3(k) shall only consist of customary written negative assurance statements.

(l) Upon commencement of the offering of Shares under this Agreement and each time the Shares are delivered to an Agent as principal on a Settlement Date, and promptly after each (i) Registration Statement Amendment Date and (ii) Company Periodic Report Date, the Company will cause KPMG LLP, or other independent accountants reasonably satisfactory to the Agents, to furnish to the Agents a letter, dated the date of effectiveness of such amendment or the date of filing of such supplement or other document with the Commission, as the case may be, in form reasonably satisfactory to the Agents and their counsel, of the same tenor as the letter referred to in Section 7(d) hereof, but modified as necessary to relate to the Registration Statement, the General Disclosure Package and the Prospectus, as amended and supplemented, or to the document incorporated by reference into the Prospectus, to the date of such letter. As used in this paragraph, to the extent there shall be an Applicable Time on or following the date referred to in clause (i) or (ii) above, promptly shall be deemed to be on or prior to the next succeeding Applicable Time. Notwithstanding the foregoing, (A) after a Company Periodic Report Date that relates to the filing of a Quarterly Report on Form 10-Q, and (B) after each Registration Statement Amendment Date (other than as the result of filing an Annual Report on Form 10-K), the Agents hereby agrees to receive a certificate of the principal financial officer of the Company, in a form and substance reasonably satisfactory to the Agents and their counsel, in lieu of a letter from KPMG LLP. Further, notwithstanding the foregoing, the Company shall not be required to furnish or cause to be furnished any such letter or certificate at any time there are no instructions to sell shares delivered pursuant to Section 2(b) or a Terms Agreement then in effect; provided, however, that such a letter or certificate, as the case may be, shall then be required to be furnished to the Agents prior to any further sales of Shares under this Agreement covering the period which would most recently have been required but for this sentence.

(m) The Company consents to the Agents trading in the Company’s Shares for each Agent’s own account and for the account of its clients at the same time as sales of Shares occur pursuant to this Agreement or any Terms Agreement; provided, that, at all times, such Agent is in compliance with Regulation M under the 1934 Act with respect to the Shares; provided further, that in no event shall such Agent trade the Shares for its or its affiliates’ proprietary accounts.

(n) [Reserved].

(o) The Company will cooperate timely with any reasonable due diligence review conducted by the Agents or their counsel from time to time in connection with the transactions contemplated hereby or in any Terms Agreement, including, without limitation, and upon reasonable notice providing information and making available documents and appropriate corporate officers, during regular business hours and at the Company’s principal offices, as the Agents may reasonably request.

(p) During each period commencing on the date on which the Company has given an instruction pursuant to Section 2(b) and ending on the close of business of the Settlement Date of the last Shares sold pursuant to such instruction, the Company will not, without giving the Agents at least two business days’ prior written notice of a proposed sale or other transaction (which notice shall not be required to specify the nature of such proposed transaction), (A) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, lend or otherwise transfer or dispose of, or effect a reverse stock split, recapitalization, share consolidation, reclassification or similar transaction affecting the outstanding Shares, directly or indirectly, any Shares or securities convertible into or exchangeable or exercisable for or repayable with Shares, or file any registration statement under the 1933 Act with respect to any of the foregoing (other than a shelf registration statement under Rule 415 under the 1933 Act, a registration statement on Form S-8 or post-effective amendment to the Registration Statement); or (B) enter into any swap or other agreement or any transaction that transfers in whole or in part, directly or indirectly, any of the economic consequence of ownership of the Shares, or any securities convertible into or exchangeable or exercisable for or repayable with Shares, whether any such swap or transaction described in clause (A) or (B) above is to be settled by delivery of Shares or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (i) the Shares to be offered and sold through the Agents pursuant to this Agreement or any Terms Agreement, (ii) equity incentive awards approved by the board of directors of the Company, the compensation committee thereof or an authorized delegate of the compensation committee or the issuance of Shares upon exercise thereof, (iii) Shares or securities convertible into or exchangeable for Shares as consideration for mergers, acquisitions, other business combinations, joint ventures or strategic alliances occurring after the date of this Agreement which are not used for capital raising purposes and (iv) Shares issuable upon exercise or conversion of outstanding warrants, options or other derivative securities, including, without limitation, the Company’s Series 1 Preferred Shares. On or after the date hereof, the Company will not directly or indirectly enter into any other “at-the-market” or continuous equity transaction offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Shares (other than the Shares offered pursuant to this Agreement) or securities convertible into or exchangeable for Shares, warrants or any rights to purchase or acquire, Shares prior to the termination of this Agreement; provided, that nothing in this sentence shall limit the Company’s ability to offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Shares or securities convertible into or exchangeable for Shares, warrants or any rights to purchase or acquire, Shares by any method other than an “at-the-market offering” as defined in Rule 415(a)(4) under the ▇▇▇▇ ▇▇▇.

(q) If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Shares remain unsold, the Company may, prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, an “automatic shelf registration statement” (as defined in Rule 405 under the ▇▇▇▇ ▇▇▇) relating to the Shares, in a form reasonably satisfactory to the Agents. If the Company is not eligible to file an automatic shelf registration statement, the Company may, prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Shares, in a form reasonably satisfactory to the Agents, and, if such new shelf registration statement is filed, use its commercially reasonable efforts to cause such registration statement to be declared effective within 60 days after the Renewal Deadline. If a new shelf registration statement is filed pursuant to this Section 3(q), the Company will use commercially reasonable efforts to take all other action necessary or appropriate to permit the issuance and sale of the Shares to continue as contemplated in the expired registration statement relating to the Shares. References herein to the Registration Statement shall include any such new automatic shelf registration statement or any such new shelf registration statement, as the case may be.

Section 4. Free Writing Prospectus.

(a) (i) The Company represents and agrees that without the prior consent of the Agents (which consent may not be unreasonably withheld, delayed or conditioned), it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the 1933 Act; and (ii) each Agent represents and agrees that, without the prior consent of the Company (which consent may not be unreasonably withheld, delayed or conditioned), it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus required to be filed with the Commission.

(b) The Company has complied and will comply with the requirements of Rule 433 under the 1933 Act applicable to any Issuer Free Writing Prospectus (including any free writing prospectus identified in Section 4(a) hereof), including timely filing with the Commission or retention where required and legending.

Section 5. Payment of Expenses.

(a) The Company covenants and agrees with the Agents that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Shares under the 1933 Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, the Basic Prospectus, Prospectus Supplement, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Agents; (ii) the cost of printing or producing this Agreement or any Terms Agreement, any blue sky memoranda, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Shares; (iii) all expenses in connection with the qualification of the Shares for offering and sale under state securities laws as provided in Section 3(b) hereof, including the reasonable and documented fees and disbursements of counsel for the Agents in an amount not to exceed $5,000 in connection with such qualification and in connection with the blue sky surveys; (iv) any filing fees incident to, and the reasonable and documented fees and disbursements of counsel for the Agents in an amount not to exceed $10,000 in connection with, any required review by FINRA of the terms of the sale of the Shares; (v) all fees and expenses in connection with listing the Shares on the Nasdaq; (vi) the cost of preparing the Shares; (vii) the costs and charges of any transfer agent or registrar or any dividend distribution agent; and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section.

(b) Each Agent shall be responsible for all of its out-of-pocket expenses, including the reasonable fees and disbursements of U.S. and Canadian counsel for the Agents; provided, however, that if less than $5 million of Shares are sold pursuant to this Agreement prior to its termination, then, in connection with termination of the Agreement, the Company shall reimburse the Agents for all of their reasonable and documented out-of-pocket expenses, including the reasonable and documented fees and disbursements of U.S. and Canadian counsel for the Agents, incurred by the Agents in connection with the offering contemplated by this Agreement, up to an aggregate amount of $75,000 (which amount shall include the reasonable and documented fees and disbursements of counsel incurred pursuant to Section 5(a)(iii) and (iv)); provided further, however, that if any Shares are sold pursuant to this Agreement (but less than $5 million of gross proceeds of Shares), the Company shall reimburse the Agents for an amount equal to the product of $75,000*(1-(gross proceeds of Shares sold under this Agreement/5,000,000)) (which amount shall include the reasonable and documented fees and disbursements of counsel incurred pursuant to Section 5(a)(iii) and (iv)).

Section 6. Representations and Covenants of Agents. Each of the Agents represents and warrants that it is duly registered as a broker-dealer under FINRA, the 1934 Act and the applicable statutes and regulations of each state in which the Shares will be offered and sold, except such states in which such Agent is exempt from registration or such registration is not otherwise required. Each of the Agents shall continue, for the term of this Agreement, to be duly registered as a broker-dealer under FINRA, the 1934 Act and the applicable statutes and regulations of each state in which the Shares will be offered and sold, except such states in which such Agent is exempt from registration or such registration is not otherwise required, during the term of this Agreement. Each of the Agents will comply in all material respects with all applicable law and regulations in connection with the Shares, including, but not limited to, Regulation M.

Section 8. Indemnification.

(a) The Company will indemnify and hold harmless the Agents against any losses, claims, damages or liabilities, joint or several, to which the Agents may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the 1933 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, and will reimburse the Agents for any legal or other expenses reasonably incurred by the Agents in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in strict conformity with the Agent Information (as defined below).

(b) Each Agent, severally but not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, 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, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Prospectus, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in strict conformity with written information furnished to the Company by the Agents expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. The Company hereby acknowledges that the only information that the Agents have furnished to the Company expressly for use in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, are the statements set forth in the ninth paragraph under the caption “Plan of Distribution” in the Prospectus (the “Agent Information”).

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above 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 subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection except and then only to the extent such indemnifying party is materially prejudiced thereby. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, 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 shall not be liable to such indemnified party under this Section 8 for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. 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 hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (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, claims, damages or liabilities (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 Agents on the other from the offering of the Shares to which such loss, claim, damage or liability (or action in respect thereof) relates. 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 Agents on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (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 Agents on the other 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 commissions received by the Agents. 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 Agents on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Agents agree that it would not be just and equitable if contribution pursuant to this subsection (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 above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (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 subsection (d), an Agent shall not be required to contribute any amount in excess of the amount by which the total compensation received by such Agent with respect to sales of the Shares sold by it to the public exceeds the amount of any damages which such Agent 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 ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Agents’ respective obligations to contribute pursuant to this Section 8(d) are several in proportion to the respective number of Shares they have sold hereunder, and not joint.

(e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to the directors, officers, employees, attorneys and agents of the Agents and to each person, if any, who controls the applicable Agent within the meaning of the 1933 Act and each broker dealer affiliate of the Agents; and the obligations of the Agents under this Section 8 shall be in addition to any liability which the Agents may otherwise have and shall extend, upon the same terms and conditions, to each director, officer, employee, attorney and agent of the Company and to each person, if any, who controls the Company within the meaning of the 1933 Act.

Section 9. Representations, Warranties and Agreements to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Agents, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Agents or any controlling person of an Agent, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Shares.

Section 10. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (i) each Agent is acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of such offering) and (ii) the Agents have not assumed 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 the Agents have advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iii) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Agents have rendered advisory services of any nature or respect, or owe a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

Section 11. Termination.

(a) 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 Agents for the Company, the obligations of the Company, including in respect of compensation of the Agents, shall remain in full force and effect notwithstanding such termination until such pending sales are settled; and (ii) the provisions of Section 1, Section 5, Section 8, Section 9, Section 15 and Section 16 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) Each Agent shall have the right, by giving written notice as hereinafter specified, to terminate its participation in this Agreement in its sole discretion at any time. The Agents shall have the right, by giving joint written notice as hereinafter specified, to terminate this Agreement in their 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, including a pending sale pursuant to a Terms Agreement, through an Agent for the Company, the obligations of the Agent, as applicable, shall remain in full force and effect notwithstanding such termination until such pending sales are settled; and (ii) the provisions of Section 1, Section 5, Section 8, Section 9, Section 15 and Section 16 of this Agreement shall remain in full force and effect notwithstanding such termination.

(c) Unless earlier terminated pursuant to this Section 11, this Agreement shall automatically terminate upon the issuance and sale of all of the Shares by the Agents on the terms and subject to the conditions set forth herein except any termination pursuant to this clause (c) shall in all cases be deemed to provide that Section 1, Section 5, Section 8, Section 9, Section 15 and Section 16 of this Agreement shall remain in full force and effect.

(d) This Agreement shall remain in full force and effect until and unless terminated pursuant to Section 11(a), (b) or (c) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement or pursuant to this clause (d) shall in all cases be deemed to provide that Section 1, Section 5, Section 8, Section 9, Section 15 and Section 16 of this Agreement shall remain in full force and effect.

(e) 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 Agents 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 2(g) hereof.

(f) In the case of any purchase by an Agent pursuant to a Terms Agreement, such Agent may terminate this Agreement, at any time at or prior to the Settlement Date of such purchase (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Prospectus, any Material Adverse Effect, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of such Agent, impracticable or inadvisable to market the Shares or to enforce contracts for the sale of Shares, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the Nasdaq, or if trading generally on the NYSE American or the NYSE or Nasdaq has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (v) if a banking moratorium has been declared by either Federal or New York authorities.

Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

Section 13. Parties. This Agreement shall be binding upon, and inure solely to the benefit of, the Agents and the Company and, to the extent provided in Sections 8 and 9 hereof, the officers, directors, employees, attorneys and agents of the Company and the Agents and each person who controls the Company or an Agent, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of Shares through the Agents shall be deemed a successor or assign by reason merely of such purchase.

Section 14. Time of the Essence. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

Section 15. Waiver of Jury Trial. The Company and the Agents hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to jury trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Section 16. Governing Law; Currency. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed in such state. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the New York Courts, and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the New York Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. The Company has irrevocably appointed CT Corporation System pursuant to a Form U-2 Uniform Consent to Service of Process filed with the Secretary of State of the State of New York, as its agent to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the Borough of Manhattan in the City of New York.

With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the New York Courts, and with respect to any Related Judgment, each party waives any such immunity in the New York Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

All references to “$” in this Agreement refer to United States dollars. The obligations of the Company pursuant to this Agreement in respect of any sum due to an Agent shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by the Agent of any sum adjudged to be so due in such other currency, on which such Agent may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due an Agent in United States dollars hereunder, the Company agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Agent against such loss. If the United States dollars so purchased are greater than the sum originally due to an Agent hereunder, such Agent agrees to pay to the Company an amount equal to the excess of the dollars so purchased over the sum originally due to such Agent hereunder.

All payments made by the Company under this Agreement, if any, will be made without withholdings or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature (other than taxes on net income) imposed or levied by or on behalf of Canada or any political subdivision or any taxing authority thereof or therein unless the Company is or becomes required by law to withhold or deduct such taxes, duties, assessments or other governmental charges. In such event, the Company will pay such additional amounts as will result, after such withholding or deduction, in the receipt by an Agent of the amounts that would otherwise have been receivable in respect thereof; provided, however that no such additional amounts will be payable in the case of any such additional amounts required to be deducted or withheld by applicable law: (i) that are in respect of services performed by or on behalf of such Agent in Canada; (ii) that are in respect of services performed by or on behalf of such Agent outside of Canada unless such services are performed in the ordinary course of a business carried on by such Agent that included the performance of such services for a fee; (iii) that are in respect of interest paid or credited to such Agent if the Agent does not deal at arm’s length for purposes of the Income Tax Act (Canada) with the Company; or (iv) that are in respect of interest paid to a “specified shareholder” of the Company for purposes of subsection 18(5) of the Income Tax Act (Canada) or a person who does not deal at arm’s length with such a “specified shareholder”. For greater certainty, the Company will not be responsible for any such additional amounts: (i) that are in respect of an Agent being resident in Canada for purposes of the Income Tax Act (Canada) or being an insurer that carries on an insurance business in Canada and elsewhere; or (ii) that are in respect of an Agent carrying on business in Canada for purposes of the Income Tax Act (Canada).

Section 17. Counterparts. This Agreement, any Terms Agreement and any documents provided to the other party pursuant to this Agreement or any Terms Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. This Agreement, any Terms Agreement and any documents provided to the other party pursuant to this Agreement or any Terms Agreement may be delivered by any party by facsimile or other electronic transmission.

Section 18. Severability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among each of the Agents and the Company in accordance with its terms.

Attn: Syndicate Department]

Ladies and Gentlemen:

Xenon Pharmaceuticals Inc., a corporation continued under the federal laws of Canada (the “Company”), proposes, subject to the terms and conditions stated herein and in the At-the-Market Equity Offering Sales Agreement, dated August 6, 2020 (the “Sales Agreement”), among the Company, ▇▇▇▇▇▇▇▇▇ LLC and ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ & Company, Incorporated to issue and sell to [name of designated agent] (the ”Designated Agent”) the securities specified in the Schedule hereto (the “Purchased Securities”) [, and solely for the purpose of covering over-allotments, to grant to the Designated Agent the option to purchase the additional securities specified in the Schedule hereto (the “Additional Securities”)]*.

[The Designated Agent shall have the right to purchase from the Company all or a portion of the Additional Securities as may be necessary to cover over-allotments made in connection with the offering of the Purchased Securities, at the same purchase price per share to be paid by the Designated Agent to the Company for the Purchased Securities. This option may be exercised by the Designated Agent at any time (but not more than once) on or before the thirtieth day following the date hereof, by written notice to the Company. Such notice shall set forth the aggregate number of shares of Additional Securities as to which the option is being exercised, and the date and time when the Additional Securities are to be delivered (such date and time being herein referred to as the “Option Closing Date”); provided, however, that the Option Closing Date shall not be earlier than the Time of Delivery (as set forth in the Schedule hereto) nor earlier than the second business day after the date on which the option shall have been exercised nor later than the fifth business day after the date on which the option shall have been exercised. Payment of the purchase price for the Additional Securities shall be made at the Option Closing Date in the same manner and at the same office as the payment for the Purchased Securities.]*

Each of the provisions of the Sales Agreement not specifically related to the solicitation by the Designated Agent, as agent of the Company, of offers to purchase securities is incorporated herein by reference in its entirety, and shall be deemed to be part of this Terms Agreement to the same extent as if such provisions had been set forth in full herein. Each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Terms Agreement [and] [,] the Applicable Time [and any Option Closing Date]*, except that each representation and warranty in Section 1 of the Sales Agreement which makes reference to the Prospectus (as therein defined) shall be deemed to be a representation and warranty as of the date of the Sales Agreement in relation to the Prospectus, and also a representation and warranty as of the date of this Terms Agreement [and] [,] the Settlement Date [and any Option Closing Date]* in relation to the Prospectus as amended and supplemented to relate to the Purchased Securities.

An amendment to the Registration Statement (as defined in the Sales Agreement), or a supplement to the Prospectus, as the case may be, relating to the Purchased Securities [and the Additional Securities]*, in the form heretofore delivered to the Designated Agent is now proposed to be filed with the Securities and Exchange Commission.

Subject to the terms and conditions set forth herein and in the Sales Agreement which are incorporated herein by reference, the Company agrees to issue and sell to the Designated Agent and the latter agrees to purchase from the Company the number of shares of the Purchased Securities at the time and place and at the purchase price set forth in the Schedule hereto.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement between the Designated Agent and the Company in accordance with its terms.

Very truly yours,
