Moreover, the Company hereby agrees to issue and sell up to Additional Shares to the Underwriters at the Purchase Price and the Underwriters, upon the basis of the representations and warranties contained herein, but subject to the terms and conditions herein set forth, shall have the right (but not the obligation) to purchase, severally and not jointly, up to the Additional Shares at the Purchase Price.

Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel and the Company’s accountants in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company, and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any securities or blue sky memorandum in connection with the offer and sale of the Shares under the securities laws of the jurisdictions in which the Shares may be offered or sold and all expenses in connection with the qualification of the Shares for offer and sale under such securities laws as provided in Section 6(k) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with a “blue sky” memorandum, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Shares by FINRA, (v) all fees and expenses in connection with the preparation and filing of the registration statement on Form 8-A relating to the Common Stock and all costs and expenses incident to listing the Shares on the Exchange, (vi) the cost of printing certificates representing the Shares, (vii) the costs and charges of any transfer agent, registrar or depositary, (viii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the Offering, including, without limitation, expenses associated with the preparation or dissemination of any road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel (including the cost of any chartered aircraft) and lodging expenses of the representatives and officers of the Company and any such consultants, (ix) the document production charges and expenses associated with printing this Agreement, (x) all expenses in connection with any offer and sale of the Shares outside of the United States,

including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with offers and sales outside of the United States and the preparation of any prospectus wrappers or disclosures deemed advisable or necessary to comply with foreign securities laws, (xi) all fees and disbursements of counsel incurred by the Underwriters in connection with the Directed Share Program and stamp duties, similar taxes or duties or other taxes, if any, incurred by the Underwriters in connection with the Directed Share Program and (xii) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section.

Except as expressly set forth herein, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make. Notwithstanding the above, if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 5 is not satisfied, because of any termination of this Agreement by the Underwriters pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any obligation or covenant hereunder or comply with any provision hereof other than by reason of a default by any of the Underwriters, then the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by such Underwriters in connection with this Agreement or in furtherance of the Offering; provided, however, that such reimbursement shall not exceed $400,000.

8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities, including actions and other proceedings in respect thereof and including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such claim, action or other proceeding (any of the foregoing being a “Loss”), caused by, arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, any issuer information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment, supplement or wrapper thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Company shall not be liable under this Section 8(a) to the extent that such Losses are caused by, arise out of or are based upon any such untrue statement or omission or alleged

untrue statement or omission made therein in reliance upon and in conformity with the Underwriter Information furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all Losses caused by, arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, any issuer information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment, supplement or wrapper thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or omission or alleged untrue statement or omission was made therein in reliance upon and in conformity with the Underwriter Information furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein.

(c) In case any claim, action or other proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate law firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act and (ii) the fees

and expenses of more than one separate law firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section. In the case of any such separate law firm for the Underwriters and such control persons and affiliates of any Underwriters, such law firm shall be designated in writing by the Representatives and shall be reasonably satisfactory to the Company. In the case of any such separate law firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, then the indemnifying party agrees to indemnify the indemnified party from and against any Loss by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into in good faith more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request and shall not have contested the reasonableness of such fees and expenses, in each case, prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on Losses that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any Losses referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the Offering or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the Offering shall be deemed to be in the same respective proportions as the net proceeds from the Offering (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The

relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 8(e). Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

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

9. Directed Share Program Indemnification. (a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act (the “Underwriter Entities”) from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company for distribution to Participants in connection with the Directed Share Program or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Company shall not be liable under this Section 9(a) to the extent that such losses, claims, damages and liabilities are caused

by, arise out of or are based upon any such untrue statement or omission or alleged untrue statement or omission made therein in reliance upon and in conformity with the any information furnished to the Company in writing by any Underwriter Entity through the Representatives expressly for use therein; (ii) caused by the failure of any Participant to pay for and accept delivery of Directed Shares that the Participant agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Share Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of the Underwriter Entities.

(b) In case any proceeding (including any governmental investigation) shall be instituted involving any Underwriter Entity in respect of which indemnity may be sought pursuant to Section 9(a), the Underwriter Entity seeking indemnity, shall promptly notify the Company in writing and the Company, upon request of the Underwriter Entity, shall retain counsel reasonably satisfactory to the Underwriter Entity to represent the Underwriter Entity and any others the Company may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any Underwriter Entity shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Underwriter Entity unless (i) the Company shall have agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Company and the Underwriter Entity and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not, in respect of the legal expenses of the Underwriter Entities in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate law firm (in addition to any local counsel) for all Underwriter Entities. Any such separate firm for the Underwriter Entities shall be designated in writing by the Representatives. The Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Company agrees to indemnify the Underwriter Entities from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Underwriter Entity shall have requested the Company to reimburse it for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the Company agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into in good faith more than 30 days after receipt by the Company of the aforesaid request and (ii) the Company shall not have reimbursed the Underwriter Entity in accordance with such request and shall not have contested the reasonableness of such fees and expenses, in each case, prior to the date of such settlement. The Company shall not, without the prior written consent of the Representatives, effect any settlement of any pending or threatened proceeding in respect of which any Underwriter Entity is or could have been a party and indemnity could have been sought hereunder by such Underwriter Entity, unless such settlement includes an unconditional release of the Underwriter Entities from all liability on claims that are the subject matter of such proceeding.

(c) To the extent the indemnification provided for in Section 9(a) is unavailable to an Underwriter Entity or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the Company in lieu of indemnifying the Underwriter Entity thereunder, shall contribute to the amount paid or payable by the Underwriter Entity as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter Entities on the other hand from the offering of the Directed Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriter Entities on the other hand in connection with any statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter Entities on the other hand in connection with the offering of the Directed Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Directed Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriter Entities for the Directed Shares, bear to the aggregate Public Offering Price of the Directed Shares. If the loss, claim, damage or liability is caused by an untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact, the relative fault of the Company on the one hand and the Underwriter Entities on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriter Entities and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(d) The Company and the Underwriter Entities agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriter Entities were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(c). Notwithstanding the provisions of this Section 9, no Underwriter Entity shall be required to contribute any amount in excess of the amount by which the total price at which the Directed Shares were offered to the Participants exceeds the amount of any damages that such Underwriter Entity has otherwise been required to pay. No person guilty of fraudulent misrepresentation (within the meaning of Section 9(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(e) The indemnity and contribution provisions contained in this Section 9 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter Entity or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Directed Shares.

10. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (a) there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the Time of Sale Prospectus or the Prospectus, any material adverse effect, whether or not arising in the ordinary course of business, (b) trading generally shall have been suspended or materially limited or minimum or maximum prices shall have been established, or maximum ranges for prices have been required, on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT, LLC, or the NASDAQ Global Market, or by order of the Commission or FINRA or any other governmental authority, (c) trading of any securities of the Company shall have been suspended or materially limited on any exchange or in any over-the-counter market, (d) any moratorium or material limitation on commercial banking activities shall have been declared by Federal or Texas authorities, (e) there shall have occurred any outbreak or escalation of hostilities, act of terrorism involving the United States or declaration by the United States of a national emergency or war, or (f) any other calamity or crisis or any material adverse change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (e) or (f), makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

11. Effectiveness; Defaulting Underwriters. (a) This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

(a) If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date (the “Defaulted Shares”), then the Representatives shall have the right in their discretion to arrange for the purchase by one or more of the non-defaulting Underwriters, or any other underwriters reasonably satisfactory to the Company, of all but not less than all of the Defaulted Shares in such amounts as may be agreed upon and upon the terms herein set forth. If within 36 hours after such default by any Underwriter, the Representatives do not arrange for the purchase of such Defaulted Shares, then the Company shall be entitled to a further period of 36 hours (which may be waived by the Company) within which to procure another party or other parties reasonably satisfactory to the Representatives to purchase the Defaulted Shares on such terms as are acceptable to the Company. In the event that, within the respective prescribed periods, the Representatives notify the Company that it has so arranged for the purchase of the Defaulted Shares, or the Company notifies the Representatives that it has so arranged for the purchase of the Defaulted Shares, the Representatives or the Company shall have the right to postpone the Closing Date or an Option Closing Date, as the case may be, for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration

Statement, the Time of Sale Prospectus or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement, the Time of Sale Prospectus or the Prospectus which may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to the Defaulted Shares.

(b) If, after giving effect to any arrangements for the purchase of Defaulted Shares by the Representatives or the Company as provided in subsection (a) above, the aggregate number of Defaulted Shares that remains unpurchased does not exceed one-tenth of the aggregate number of the Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase under this Agreement at the Closing Date or an Option Closing Date, as the case may be, and, in addition, to require each non-defaulting Underwriter to purchase its pro rata shares (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Defaulted Shares for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of Defaulted Shares by the Representatives or the Company as provided above, the aggregate number of Defaulted Shares that remains unpurchased exceeds one-tenth of the aggregate number of the Shares to be purchased on the Closing Date or an Option Closing Date, as the case may be, or if the Company shall not exercise the right described in subsection (b) above to require the non-defaulting Underwriters to purchase the Defaulted Shares, then this Agreement (or, with respect to an Option Closing Date, the obligations of the Underwriters to sell the Additional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for expenses to be borne by the Company and the Underwriters as provided in Section 7 and the indemnification and contribution agreements in Sections 8 and 9 hereof; but nothing herein shall relieve any defaulting Underwriter from liability for its default.

12. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company and the Underwriters set forth 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 or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Shares. The provisions of Sections 7, 8 and 9 hereof shall survive the termination or cancellation of this Agreement.

13. Entire Agreement; No Advisory or Fiduciary Relationship. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this agreement) that relate to the offering of the Shares, represents the entire agreement between the Company, on the

one hand, and the Underwriters, on the other, with respect to the preparation of any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person; (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any; (iii) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the Offering and the Company has consulted its respective legal, accounting, regulatory and tax advisors to the extent that it, she or he deemed appropriate; and (iv) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the Offering.

14. Intended Beneficiaries. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors. No purchaser of Shares from any Underwriter shall be deemed to be a successor by reason merely of such purchase. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any individual or entity, other than the Underwriters, the Company and their respective successors, and the controlling persons, affiliates, officers and directors referred to in Sections 7, 8 and 9 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement is intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and said controlling persons, affiliates, officers and directors and their heirs and legal representatives, and for the benefit of no one else.

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

16. Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

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

18. TRIAL BY JURY. THE COMPANY (ON ITS BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS SUBSIDIARIES, SHAREHOLDERS AND AFFILIATES) AND EACH OF THE UNDERWRITERS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

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

20. Notices. All communications hereunder shall be in writing and effective only upon receipt and shall be delivered, mailed or sent to the parties as follows:

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, which shall not be unreasonably withheld, it will not, during a period of 180 days from the date of the Underwriting Agreement (the “Restricted Period”), (1) directly or indirectly offer, sell, pledge, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, make any short sale, lend, or otherwise transfer or dispose of, or establish or increase any “put equivalent position” or liquidate or decrease any “call equivalent position” (each within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) with respect to any shares of Common Stock, any options or warrants to purchase any shares of Common Stock, or any securities convertible into or exercisable or exchangeable for or that represent the right to receive shares of Common Stock, (2) enter into any swap, forward contract, hedging transaction or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, (3) file or approve the filing of any registration statement with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or

make any demand for or exercise any right with respect to (other than piggyback registration rights, if any) the registration of any shares of Common Stock or the filing of any registration statement with respect thereto, or (4) publicly disclose or announce an intention to effect any transaction specified in clause (1), (2) or (3). The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer by the undersigned of shares of Common Stock except in compliance with this agreement.

The foregoing restrictions shall not apply to (a) the sale of the Shares in the Public Offering, (b) sales of shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with such sales, (c) transfers of shares of Common Stock or any security convertible into Common Stock as a bona fide gift, (d) transfers by will or estate or intestate succession to the undersigned’s family, or to a trust, the beneficiaries of which are exclusively the undersigned or members of the undersigned’s family, or to a charitable organization, (e) transfers or distributions, if the undersigned is not a natural person, of shares of Common Stock or any security convertible into Common Stock to limited partners, members, subsidiaries, stockholders or affiliates of the undersigned to the extent the undersigned is a partnership, limited liability company or corporation, (f) shares of Common Stock pledged in a bona fide transaction outstanding as of the date hereof to a lender to the undersigned and disclosed in an appendix to this letter, or (g) the exercise of any options to purchase shares of Common Stock or the vesting, award, delivery or settlement of shares of Common Stock and the receipt by the undersigned from the Company of shares of Common Stock thereunder, in each case pursuant to the Company’s stock option or equity-based compensation plans that are described in the registration statement and prospectus related to the Public Offering, and sales of such shares of Common Stock in transactions exempt from Section 16(b) of the Exchange Act that are issued upon exercise of such options or warrants or such vesting, award, delivery, settlement or receipt in order to pay or provide for any taxes due on such exercise, vesting, delivery, settlement or receipt or to pay the exercise price therefor; provided that in the case of any transfer, distribution or issuance pursuant to clause (c), (d) or (e), each donee, heir, legatee, trustee, distributee, transferee or recipient shall sign and deliver a lock-up letter substantially in the form of this letter for the balance of the Restricted Period. In furtherance of the foregoing, the Company is hereby authorized to decline to make or authorize any transfer of securities if such transfer would constitute a violation of breach of the restrictions contained herein.

The undersigned understands that, if the undersigned is an officer or director of the Company, (1) this agreement shall be applicable to any issuer-directed shares that the undersigned may purchase in the Public Offering, (2) the Representatives will notify the Company at least three business days before the effective date of any release or waiver of the foregoing restrictions, (3) the Company will announce the impending release or waiver by a press release through a major news service announcing such waiver or release, and (4) any release or waiver granted by the Representatives under this agreement will only be effective two business days after the publication date of such press release.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

It is understood that, if the Company notifies the Representatives in writing that it does not intend to proceed with the Public Offering, if the Underwriting Agreement shall terminate or be terminated prior to the payment for and delivery of the Shares to be sold thereunder or if the Offering is not completed on or before , 2015, this agreement shall be terminated and be of no further force or effect.

Very truly yours,
