1. Representations and Warranties: (i) The Company represents and warrants to, and agrees with, the Underwriter as set forth below in this Section 1(i).

(a) The Company meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission an automatically effective Registration Statement for registration under the Act of the offering and sale of the Securities. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing. The Company may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more preliminary prospectus supplements relating to the Securities, each of which has previously been furnished to you. The

Company will file with the Commission a final prospectus supplement relating to the Securities in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain all information required by the Act and the rules thereunder and, except to the extent the Underwriter shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the latest Base Prospectus and any Preliminary Prospectus) as the Company has advised you, prior to the Execution Time, will be included or made therein. The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x). The initial Effective Date of the Registration Statement was not earlier than the date three years before the Execution Time.

(c) At the Execution Time, (i) the Disclosure Package and (ii) each electronic road show, in each case, when taken together as a whole with the Disclosure Package, did not contain 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.

(g) No consent, approval, authorization, filing with or order of any court or governmental agency or body is required in connection with the transactions contemplated herein by the Selling Shareholder, except such as have been obtained under the Act and such as may be required under the blue sky laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriter in the manner contemplated herein and in the Disclosure Package and the Final Prospectus or when, if not obtained, would not have a Material Adverse Effect.

(h) Except as disclosed in the Registration Statement, the Disclosure Package and the Final Prospectus, no holders of securities of the Company have rights to the registration of such securities under the Registration Statement. Except as disclosed in the Registration Statement, the Disclosure Package and the Final Prospectus, the holders of outstanding shares of capital stock of the Company are not entitled to statutory preemptive or other similar contractual rights to subscribe for the Securities.

(k) The Selling Shareholder will not, directly or indirectly, use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person in any manner that will result in a violation of (i) Sanctions by, or could result in the imposition of Sanctions against, any person (including any person participating in the offering, whether as underwriter, advisor, investor or otherwise) or (ii) the Foreign Corrupt Practices Act of 1977 as amended, or the rules or regulations thereunder.

(l) The Selling Shareholder is not (A) an employee benefit plan subject to Title I of ERISA, (B) a plan or account subject to Section 4975 of the Internal Revenue Code of 1986, as amended, or (C) an entity deemed to hold “plan assets” of any such plan or account under Section 3(42) of ERISA, or otherwise.

The Selling Shareholder agrees to pay any and all fees with respect to the Securities offered and sold by the Selling Shareholder and, for the avoidance of doubt, the Company shall not reimburse the Selling Shareholder for such fees or any underwriting discounts and commissions with respect to the Securities offered and sold by the Selling Shareholder. Subject to the sale of the Securities by the Selling Shareholder to the Underwriter in compliance with the terms of this Agreement, the Underwriter agrees to sell to the Company, and the Company agrees to purchase from the Underwriter, an aggregate of 520,000 shares at the purchase price per share set forth above in this Section 2.

Delivery of the Securities shall be made to the Underwriter against payment by the Underwriter of the purchase price of the Securities being sold by the Selling Shareholder thereof to or upon the order of the Selling Shareholder by wire transfer payable in same-day funds to an account specified by the Selling Shareholder.

4. Offering by Underwriter. It is understood that the Underwriter proposes to offer the Securities for sale to the public as set forth in the Final Prospectus.

5. Agreements. The Company and the Selling Shareholder (as applicable) agree with the Underwriter that:

(a) Prior to the termination of the offering of the Securities, the Company will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Prospectus) to the Base Prospectus unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Company will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Underwriter with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence reasonably satisfactory to the Underwriter of such timely filing. The Company will promptly advise the Underwriter (i) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to

Rule 424(b), (ii) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would 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 at such time not misleading, the Company will (i) notify promptly the Underwriter so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(c) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would 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, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Company and the Selling Shareholder, as applicable, promptly will (i) notify the Underwriter of any such event; (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance; and (iii) use its best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.

(d) As soon as practicable, the Company will make generally available to its security holders and to the Underwriter an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158 of the Act.

(e) The Company will furnish to the Underwriter and counsel for the Underwriter, without charge, signed copies of the Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Underwriter may reasonably request. The Selling Shareholder will pay the expenses of printing or other production of all documents relating to the offering.

(f) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Underwriter may designate and will maintain such qualifications in effect so long as required for the distribution of the Securities; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.

(g) The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r)

(h) Neither the Company nor the Selling Shareholder will take, directly or indirectly, any action designed to or that would constitute or that would reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(i) The Selling Shareholder agrees to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities, including any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Securities; (v) the registration of the Securities under the Exchange Act and the listing of the Securities on the New York Stock Exchange; (vi) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriter relating to such registration and qualification, not to exceed $10,000); (vii) any filings required to be made with the Financial Industry Regulatory Authority, Inc. (“FINRA”) (including filing fees and the reasonable fees and expenses of counsel for the Underwriter relating to such filings, not to exceed $25,000); (viii) the transportation and other expenses incurred by or on behalf of Company representatives in connection with presentations to prospective purchasers of the Securities; (ix) the fees and expenses of the Company, ▇▇▇▇▇ LLC, Trican and RockPile’s accountants and the fees and expenses of its counsel and counsel for the Selling Shareholder (including local and special counsel) and financial advisors for the Company and the Selling Shareholder; and (x) all other costs and expenses incident to the performance by the Company and the Selling Shareholder of their obligations hereunder. In addition to the fees and expenses provided for above, the Selling Stockholder will pay, without duplication, the Underwriter’s reasonable documented costs and expenses relating to the fees of its counsel, stock transfer taxes on resale of any of the Common Stock by the Underwriter, and advertising expenses connected with any offers the Underwriter may make.

(j) The Company and the Selling Shareholder agree that, unless it has or shall have obtained the prior written consent of the Underwriter, and the Underwriter agrees with the Company that, unless it has or shall have obtained, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule I hereto and any electronic road show. Any such free writing prospectus consented to by the Underwriter or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

6. Conditions to the Obligations of the Underwriter. The obligations of the Underwriter to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company and the Selling Shareholder contained herein as of the Execution Time and the Closing Date pursuant to Section 3 hereof, to the accuracy of the statements of the Company and the Selling Shareholder made in any certificates pursuant to the provisions hereof, to the performance by the Company and the Selling Shareholder of its obligations hereunder and to the following additional conditions:

(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened; and

(iii) since the date of the most recent financial statements included or incorporated by reference in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto), there has been no Material Adverse Effect.

(e) The Selling Shareholder shall have furnished to the Underwriter a certificate, signed by an authorized person of the Selling Shareholder, dated the Closing Date, to the effect that the signer of such certificate has carefully examined the Registration Statement, the Disclosure Package, the Final Prospectus, any Issuer Free Writing Prospectus and any amendment or supplement thereto and this Agreement and that the representations and warranties of the Selling Shareholder in this Agreement are true and correct on and as of the Closing Date to the same effect as if made on the Closing Date and the Selling Shareholder has complied with all the agreements and satisfied all of the conditions on its part to be performed or satisfied at or prior to the Closing Date.

7. Reimbursement of Underwriter’s Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriter set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 9 hereof or because of any refusal, inability or failure on the part of the Company or the Selling Shareholder to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Underwriter, the Company will reimburse the Underwriter on demand for all expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by the Underwriter in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution.

(a) The Company and the Selling Shareholder agree to, jointly and severally, indemnify and hold harmless the Underwriter, the directors, officers, employees, affiliates and agents of the Underwriter and each person who controls the Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in any Preliminary Prospectus, or the Final Prospectus, any Issuer Free Writing Prospectus, any “road show” (as defined in Rule 433(h) under the Act), or, in each case, in any amendment thereof or supplement thereto 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 in order to make the statements therein (in the case of the Base Prospectus or any other preliminary supplement relating to the Securities, any Preliminary Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus, or any amendment or supplement thereto, in light of the circumstances in which they are made) not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company and the Selling Shareholder will 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 any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriter specifically for inclusion therein, it being understood and agreed that the only such information furnished by the Underwriter consists of the information described as such in Section 8(b) below, and further provided, that the Selling Shareholder may be liable only in such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon statements or omissions made in reliance upon and in conformity with information relating to the Selling Shareholder furnished to the Company in writing by the Selling Shareholder expressly for use in the Disclosure Package or the Final Prospectus, as amended or supplemented, it being understood and agreed that the only such information furnished by the Selling Shareholder consists of the name and beneficial ownership information about the Selling Shareholder set forth in the “Principal and Selling Stockholders” section of the Final Prospectus. The indemnity agreement in this clause (a) will be in addition to any liability which the Company or the Selling Shareholder may otherwise have.

(b) The Underwriter agrees to indemnify and hold harmless the Company and its respective directors, the Selling Shareholder and, to the extent applicable, each of its managers, each of the Company’s officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Underwriter, but only with reference to written information relating to the Underwriter furnished to the Company by or on behalf of the Underwriter specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Underwriter may otherwise have. The Company and the Selling Shareholder acknowledges that the statements set forth in (i) the sentences related to concessions and reallowances in the fifth paragraph under the heading “Underwriting” and (ii) the sentences related to stabilization, syndicate covering transactions and penalty bids in the eighth and ninth paragraphs under the heading “Underwriting” in the Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the Underwriter for inclusion in the Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel (which, if the Company is the indemnifying party, shall be limited to one counsel for the Underwriter, together with all persons who control the Underwriter) if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) 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 the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include an admission of fault.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Selling Shareholder, jointly and severally, and the Underwriter agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company, the Selling Shareholder and the Underwriter may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriter on the other from the offering of the Securities. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company, the Selling Shareholder and the Underwriter severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Shareholder on the one hand and of the Underwriter on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company and the Selling Shareholder shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriter shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things,

whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company or the Selling Shareholder on the one hand or the Underwriter on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Selling Shareholder and the Underwriter agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), in no event shall the Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by the Underwriter with respect to the offering of the Securities exceeds the amount of any damages that the 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. For purposes of this Section 8, each person who controls the Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, affiliate and agent of the Underwriter shall have the same rights to contribution as the Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

The liability of the Selling Shareholder under the indemnity and contribution agreements contained in this Section 8 shall be limited to an amount equal to the public offering price of the Securities sold by the Selling Shareholder to the Underwriter. The Company and the Selling Shareholder may agree, as among themselves and without limiting the rights of the Underwriter under this Agreement, as to the respective amounts of such liability for which they each shall be responsible. In addition, as solely between the Company and the Selling Shareholder, nothing herein shall supersede the indemnification and expense reimbursement provisions set forth in the Stockholders’ Agreement (as referred to in the Disclosure Package and the Final Prospectus) between the Company, the Selling Shareholder, and certain other stockholders of the Company party thereto.

9. Termination. This Agreement shall be subject to termination in the absolute discretion of the Underwriter, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such delivery and payment (i) trading in the Company’s Common Stock shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange or the NASDAQ Global Market shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities, (iii) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Underwriter, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Preliminary Prospectus or the Final Prospectus (exclusive of any supplement thereto).

10. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company, its respective officers, the Selling Shareholder and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Selling Shareholder or the Company or any of the officers, directors, employees, agents, affiliates or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof and this Section 10 shall survive the termination or cancellation of this Agreement.

Furthermore, the Company and the Selling Shareholder agree that each is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Underwriter has advised or is currently advising the Company and the Selling Shareholder on related or other matters). The Company and the Selling Shareholder agree that each will not claim that the Underwriter have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company and the Selling Shareholder in connection with such transaction or the process leading thereto.
