Each “employee benefit plan” for which the Company, any of the Company’s subsidiaries or any of their respective ERISA Affiliates would have any liability that is intended

to be qualified under Section 401(a) of the Code is so qualified in all material respects and, to the Company’s knowledge, nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification. “ERISA Affiliate” means, with respect to the Company or any of its subsidiaries, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Code or Section 4001(b) of ERISA of which the Company or such subsidiary is a member.

(b) To cause to be prepared and delivered, at its expense, within one business day from the effective date of this Agreement, to Baird and the other Underwriters an “electronic Prospectus” to be used by the Underwriters in connection with the offering and sale of the Shares. As used herein, the term “electronic Prospectus” means a form of Time of Sale Prospectus, and any amendment or supplement thereto, that meets each of the following conditions: (i) it shall be encoded in an electronic format, satisfactory to Baird, including, but not limited to, portable document format, or PDF, that may be transmitted electronically by Baird and the other Underwriters to offerees and purchasers of the Shares; and (ii) it shall disclose the same information as the paper Time of Sale Prospectus, except to the extent that graphic and image material cannot be disseminated electronically, in which case such graphic and image material shall be replaced in the electronic Prospectus with a fair and accurate narrative description or tabular representation of such material, as appropriate. The Company hereby confirms that it has included or will include in the Prospectus filed pursuant to EDGAR or otherwise with the Commission and in the Registration Statement at the time it was declared effective an undertaking that, upon receipt of a request by an investor or his or her representative, the Company shall transmit or cause to be transmitted promptly, without charge, a paper copy of the Time of Sale Prospectus.

(c) Before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus, to furnish to Baird a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which Baird objects, to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act the Prospectus required to be filed pursuant to such Rule, to file any issuer free writing prospectus to the extent required by Rule 433 under the Securities Act.

(d) To furnish to Baird a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not to use or refer to any proposed free writing prospectus to which Baird objects.

(e) Not to take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriter that the Underwriter otherwise would not have been required to file thereunder.

(f) To advise Baird promptly (i) when the Registration Statement has become effective, (ii) when any amendment to the Registration Statement has been filed or becomes effective, (iii) when any supplement to the Prospectus or any issuer free writing prospectus or any Permitted Testing-the-Waters Communication or any amendment to the Prospectus has been filed or distributed, (iv) of any request by the Commission for amendments or supplements to the Registration Statement, any Preliminary Prospectus or Prospectus or for additional information with respect thereto, or (v) of notice of institution of proceedings for, or the entry of a stop order, suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus; and if the Commission should enter such a stop order, to use its best efforts to obtain the lifting or removal of such order as soon as possible.

(g) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(h) If, during such period after the first date of the Offering as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses Baird will furnish to the Company) to which Shares may have been sold by Baird on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

(i) If, at or after the time this Agreement is executed and delivered, it is necessary or appropriate for a post-effective amendment to the Registration Statement, or a Rule 462 Registration Statement, to be filed with the Commission and become effective before the Shares may be sold, the Company will use its best efforts to cause such post-effective amendment or such Registration Statement to be filed and become effective, and will pay any applicable fees in accordance with the Securities Act, as soon as possible; and the Company will advise Baird promptly and, if requested by Baird, will confirm such advice in writing, (i) when such post-effective amendment or such Registration Statement has become effective, and (ii) if Rule 430A or 430C under the Securities Act is used, when the Prospectus is filed with the Commission pursuant to Rule 424(b) under the Securities Act (which the Company agrees to file in a timely manner in accordance with such Rules).

(j) To file in a timely manner all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus (or, in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is required in connection with the offering or sale of the Shares.

(k) Promptly to furnish such information or to take such action as Baird may reasonably request and otherwise to qualify the Shares for offer and sale under the securities or “blue sky” laws of such states and other jurisdictions (domestic or foreign) as Baird shall reasonably request, and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Shares; provided, however, that the Company shall not be required to qualify as a foreign corporation or to file a consent to service of process in any jurisdiction (excluding service of process with respect to the offer and sale of the Shares); and to promptly advise Baird of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for offer or sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(l) To make generally available to the Company’s security holders and to Baird as soon as practicable an earnings statement covering a period of at least 12 months beginning after the effective date of the Registration Statement (as defined in Rule 158(c) under the Securities Act), which shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

(m) To use its best efforts to cause the Shares to be listed on the Exchange and to maintain such listing.

(w) If at any time following the distribution of any Permitted Testing-the-Waters Communication, there occurred or occurs an event or development as a result of which such Permitted Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Permitted Testing-the-Waters Communication to eliminate or correct such untrue statement or omission.

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 and the Selling Stockholders’ obligations (excluding fees and expenses of counsel for and other advisors to the Selling Stockholders) 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

10. 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, any road show, any Written Testing-the-Waters Communication or the Prospectus or any amendment or 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 10(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 Baird expressly for use therein.

(b) Each Selling Stockholder agrees, severally and not jointly, 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 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, any Written Testing-the-Waters Communication or the Prospectus or any amendment or 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 Selling Stockholder Information relating to such Selling Stockholder furnished in writing by or on behalf of such Selling Stockholder expressly for use therein. The liability of each Selling Stockholder under this Section 10(b) shall be limited to an amount equal to the aggregate Public Offering Price of the Shares sold by such Selling Stockholder under this Agreement.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Selling Stockholders, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or any Selling Stockholder 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 from 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, any road show, any Written Testing-the-Waters Communication 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 Baird expressly for use therein.

(d) 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 10(a), 10(b) or 10(c) 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, (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, and (iii) the fees and expenses of more than one separate law firm (in addition to any local counsel) for all Selling Stockholders and all persons, if any, who control any Selling Stockholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. 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 Baird. 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. In the case of any such separate law firm for the Selling Stockholders and such control persons of any Selling Stockholders, such law firm shall be designated in writing by the Selling Stockholders or those persons named as attorneys in fact for the Selling Stockholders under the Powers of Attorney. 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 more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in

respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on Losses that are the subject matter of such proceeding.

(e) To the extent the indemnification provided for in Section 10(a), 10(b) or 10(c) 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 Sellers 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 each Seller 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 Sellers 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 Sellers 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 10 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. The liability of each Selling Stockholder under the contribution agreement contained in this paragraph shall be limited to an amount equal to the net proceeds (before deducting expenses) from the Offering received by such Selling Stockholder under this Agreement.

(f) The Sellers and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 10 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 Section 10(e). Notwithstanding the provisions of this Section 10, 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 10 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.

(g) The indemnity and contribution provisions contained in this Section 10 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, any Selling Stockholder or any person controlling any Selling Stockholder, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

11. 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) (i) 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 not misleading; provided, however, that the Company shall not be liable under this Section 11(a)(i) 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 Baird 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 11(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 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 Baird. 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 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 prior to the date of such settlement. The Company shall not, without the prior written consent of Baird, 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 11(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) 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 or the omission or alleged omission 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 11 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 11(c). Notwithstanding the provisions of this Section 11, 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 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 11 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 11 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.

12. Termination. The Underwriters may terminate this Agreement by notice given by Baird 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) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (e) any moratorium or material limitation on commercial banking activities shall have been declared by Federal or state authorities, (f) 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 (g) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (f) or (g), makes it, in Baird’s 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 (exclusive of any supplement thereto).

13. 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 Baird shall have the right in its discretion to arrange for the purchase by one or more of the non-defaulting Underwriters, or any other underwriters, 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, Baird does not arrange for the purchase of such Defaulted Shares, then the Sellers shall be entitled to a further period of 36 hours (which may be waived by the Sellers) within which to procure another party or other parties satisfactory to Baird to purchase the Defaulted Shares on such terms as are acceptable to the Sellers. In the event that, within the respective prescribed periods, Baird notifies the Company that it has so arranged for the purchase of the Defaulted Shares, or the Sellers notify Baird that they have so arranged for the purchase of the Defaulted Shares, Baird or the Sellers 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 Baird or the Sellers 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 Sellers 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 Baird or the Sellers 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 Sellers 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 Sellers, except for expenses to be borne by the Company and the Underwriters as provided in Section 9 and the indemnification and contribution agreements in Sections 10 and 11 hereof; but nothing herein shall relieve any defaulting Underwriter from liability for its default.

14. Default by the Selling Stockholders. If one or more of the Selling Stockholders shall fail or refuse on the Closing Date to sell and deliver the number of Shares that the Selling Stockholder is obligated to sell hereunder, then the Underwriters may, at the option of Baird, by notice from Baird to the Company, terminate this Agreement without liability on the fault of any non-defaulting party. In any such case any of the Baird, the Company or the Selling Stockholders shall have the right to postpone the Closing Date but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus and in any other documents or arrangements may be effected. Any action taken under this Section shall not relieve the defaulting Selling Stockholder from liability in respect of any default of the Selling Stockholder under this Agreement.

15. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company, the Selling Stockholders 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, any Selling Stockholder or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 10 hereof, and will survive delivery of and payment for the Shares. The provisions of Sections 9, 10 and 11 hereof shall survive the termination or cancellation of this Agreement.

16. 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 and the Selling Stockholders, 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 and the Selling Stockholders acknowledge 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, any Selling Stockholder or any other person; (ii) the Underwriters owe the Company and the Selling Stockholders 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 each of the Company and the Selling Stockholders has consulted its, her or his 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 and the Selling Stockholders. Each of the Company and the Selling Stockholders 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.

17. Intended Beneficiaries. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company and the Selling Stockholders 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 the Selling Stockholders and their respective successors, and the controlling persons, affiliates, officers and directors referred to in Sections 9, 10 and 11 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.

18. 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.

19. 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.

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

21. TRIAL BY JURY. THE COMPANY (ON ITS BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS SUBSIDIARIES, SHAREHOLDERS AND AFFILIATES), EACH OF THE SELLING STOCKHOLDERS 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.

22. 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.
