(a) The Company agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly (other than the Lead Underwriter and Canaccord Capital Corporation who shall be obligated to purchase all of the Firm Shares if any are purchased), to purchase from the Company at the First Time of Delivery, at a purchase price per share of $7.75, the number of Firm Shares (to be adjusted by the Lead Underwriter so as to eliminate fractional shares) determined in each case by multiplying the aggregate number of Shares to be sold by the Company by a fraction, the numerator of which is the aggregate number of Firm Shares to be purchased by such Underwriter as set forth opposite the name of such Underwriter in Schedule I hereto and the denominator of which is the aggregate number of Firm Shares to be purchased by all of the Underwriters from the Company hereunder.

(b) In the event and to the extent that the Lead Underwriter shall exercise the election to purchase Optional Shares as provided below, the Company agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly (other than the Lead Underwriter and Canaccord Capital Corporation who shall be obligated to purchase all of the Optional Shares if any are purchased), to purchase from the Company, at the Second Time of Delivery, at the purchase price per share set forth in clause (a) of this Section 2, that number of Optional Shares determined by multiplying the number of Optional Shares as to which such election shall have been exercised (to be adjusted by the Lead Underwriter so as to eliminate fractional shares) by a fraction, the numerator of which is the maximum number of Optional Shares which such Underwriter is entitled to purchase as set forth opposite the name of such Underwriter in Schedule I hereto and the denominator of which is the maximum number of Optional Shares that all of the Underwriters are entitled to purchase hereunder.

(c) The Company hereby grants to the Lead Underwriter the right to purchase at its election up to 1,050,000 Optional Shares, at the purchase price per share set forth in clause (a) of this Section 2, for the sole purpose of covering sales of shares in excess of the number of Firm Shares. Any such election to purchase Optional Shares may be exercised only by written notice (the “Election Notice”) from the Lead Underwriter to the Company, given within a period of 30 calendar days after the date of this Agreement and setting forth the aggregate number of Optional Shares to be purchased and the date on which such Optional Shares are to be delivered, as determined by the Lead Underwriter but in no event earlier than the First Time of Delivery or, unless the Lead Underwriter and the Company otherwise agree in writing, earlier than two or later than ten business days after the date of such notice.

3. Offering. Upon the authorization by the Lead Underwriter of the release of the Firm Shares, the several Underwriters propose to offer the Shares for sale upon the terms and conditions set forth in the Prospectus.

4. Closing. Certificates in definitive form for the Shares to be purchased by each Underwriter hereunder, and in such denominations and registered in such names as the Lead

Underwriter may request upon at least forty-eight hours’ prior notice to the Company, shall be delivered by or on behalf of the Company to the Lead Underwriter for the account of such Underwriter, against payment by such Underwriter or on its behalf of the purchase price therefor by wire transfer of same day funds to the account specified by the Company, as their interests may appear, all at the office of Canaccord Xxxxx Inc., 00 Xxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx 00000.

Such time and date for delivery of the Firm Shares is herein called the “First Time of Delivery,” such time and date for delivery of the Optional Shares, if not the First Time of Delivery, is herein called the “Second Time of Delivery,” and each such time and date for delivery is herein called a “Time of Delivery.” Such certificates will be made available for checking and packaging at least twenty-four hours prior to each Time of Delivery at such location as the Lead Underwriter may reasonably specify. If the Underwriters so elect, delivery of the Shares may be made by credit through full fast transfer to the accounts at the Depository Trust Company designated by the Lead Underwriter.

(a) The Company will indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter or controlling person may become subject, under the 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 or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or any “road show” (as defined in Rule 433 under the Act) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”), or arise out of or are based upon the omission or alleged omission to state therein a material fact, in the case of the Registration Statement or any amendment thereto, required to be stated therein or necessary to make the statements therein not misleading and, in the case of, the Prospectus or any supplement thereto, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or a Non-Prospectus Road Show, necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and will reimburse the Underwriters for any reasonable legal expenses of one set of counsel for all of the Underwriters and one set of local counsel in each applicable jurisdiction for all of the Underwriters, and for other expenses reasonably incurred by such Underwriter 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 or the Prospectus or any such amendment or supplement thereto, any Issuer Free Writing Prospectus or any Non-Prospectus Road Show in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Lead Underwriter expressly for use therein.

(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the 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 or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Non-Prospectus Road Show, or arise out of or are based upon the omission or alleged omission to state therein a material fact, in the case of the Registration Statement or any amendment thereto, required to be stated therein or necessary to make the statements therein not misleading and, in the case of the Prospectus or any supplement thereto, any Issuer Free Writing Prospectus or any Non-Prospectus Road Show, necessary to make the statements therein, in light of the circumstances in which they were made, 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 or the Prospectus or any such amendment or supplement thereto, any Issuer Free Writing Prospectus or any Non-Prospectus Road Show in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Lead Underwriter 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.

(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; provided, however, that 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 to the extent it has been materially prejudiced by such failure. 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; provided that if the defendants in any such proceeding include both the indemnified party and the indemnifying party and the indemnified party shall have concluded that there may be legal defenses available to it which are different from or additional to those available to the indemnifying party and in conflict with the legal defenses of the indemnifying party, the indemnified party shall have the right to select separate counsel, reasonably satisfactory to the indemnifying party, to assert such legal defenses and to otherwise participate in the defense of such proceedings on behalf of such indemnified party. 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 such subsection 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) unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to one local counsel), reasonably approved by the indemnified party and reasonably satisfactory to the indemnifying party, representing the indemnified party who is a party to such proceedings), (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the proceeding or (iii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party. 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. No indemnifying party shall be liable for any settlement of any action or claim affected without its written consent, which consent shall not be unreasonably withheld.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient 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 Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, 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 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 Underwriters 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 underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus Supplement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged 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 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 subsection (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 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), no Underwriter shall be required to contribute any amount which is more than the difference between (A) the total price at which the Shares underwritten by it were sold to the public, less the proceeds received by the Company from the sale of such Shares, and (B) the amount of any damages which such Underwriter 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations 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 each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriter under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

9. [Intentionally left blank.]

10. Survival. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, 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 any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Shares.

11. Expenses of Termination. If this Agreement shall be terminated, or the transactions contemplated hereby shall not have been consummated due to any of the conditions set forth in Section 7 hereof not having been met, or the Shares are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Lead Underwriter for all out-of-pocket expenses approved in writing by the Lead Underwriter, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company shall have no further liability to any Underwriter in respect of the Shares not so delivered except as provided in Section 6 and Section 8 hereof.

12. Notice. In all dealings hereunder, the Lead Underwriter may, in its discretion, act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Lead Underwriter on behalf of the Underwriters.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the Underwriters in care of Canaccord Xxxxx Inc., 00 Xxxx Xxxxxx, 00^xx Xxxxx, Xxxxxx, Xxxxxxxxxxxxx 00000, Attention: Equity Capital Markets; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: President. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

13. Information Provided by the Underwriters and the Company.
