(ff) There are no transfer taxes or other similar fees or charges under Federal law or the laws of any state, or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance by the Company or sale by the Company of the Stock.

(gg) Neither the Company nor any of its subsidiaries is (i) in violation of its certificate of incorporation, by-laws or other organizational documents (the “Charter Documents”); (ii) in violation of any U.S. or non-U.S. federal, state or local statute, law (including, without limitation, common law) or ordinance, or any judgment, decree, rule,

There exists no condition that, with the passage of time or otherwise, would constitute (A) a violation of such Charter Documents, (B) a violation of such Applicable Laws that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, (C) a breach of or default or a “Debt Repayment Triggering Event” (as hereinafter defined) under any Applicable Agreement that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, or (D) result in the imposition of any penalty or the acceleration of any indebtedness. As used herein, a “Debt Repayment Triggering Event” means any event or condition that gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of its subsidiaries or any of their respective properties.

(hh) The Company and each of its subsidiaries (i) make and keep accurate books and records and (ii) maintain effective internal control over financial reporting as defined in Rule 13a-15 under the Exchange Act and a system of internal accounting controls sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorization, (B) transactions are recorded as necessary to permit preparation of the Company’s financial statements in conformity with GAAP and to maintain accountability for its assets, (C) access to the Company’s assets is permitted only in accordance with management’s general or specific authorization and (D) the recorded accountability for the Company’s assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any material differences.

released as of each Delivery Date. To the knowledge of the Company and its subsidiaries, after due inquiry, no claims or notices of any potential claim have been asserted by any person challenging the use of any such Intellectual Property by the Company or its subsidiaries or questioning the validity or effectiveness of any Intellectual Property or any license or agreement related thereto, other than any claims that, if successful, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. To the knowledge of the Company and its subsidiaries, after due inquiry, none of the Intellectual Property used by the Company or any of its subsidiaries has been obtained or is being used by the Company or any of its subsidiaries in violation of any contractual obligation binding on any of them or their respective officers, directors, or employees, or otherwise in violation of the rights of any person.

(l) The Registration Statement did not, as of the Effective Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided that such representation and warranty applies only to information contained in or omitted from the Registration Statement in reliance upon and in conformity with written information relating to such Selling Stockholder and furnished to the Company by or on behalf of such Selling Stockholder specifically for inclusion therein; it being understood and agreed that the only written information so furnished consists only of the information concerning such Selling Stockholder appearing under the captions “Prospectus Summary—Our Principal Stockholder” and “Principal and Selling Stockholders” in any Preliminary Prospectus, the Registration Statement and the Prospectus (the “Selling Stockholder Information”).

(m) The Prospectus will not, as of its date and on the applicable Delivery Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that such representation and warranty applies only to the Selling Stockholder Information contained in or omitted from the Prospectus.

3. Purchase of the Stock by the Underwriters. On the basis of the representations and warranties contained in, and subject to the terms and conditions of, this Agreement, the Company agrees to sell 4,000,000 shares of the Firm Stock and each Selling Stockholder agrees to sell the number of shares of the Firm Stock set forth opposite its name in Schedule 2 hereto, severally and not jointly, to the several Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase the number of shares of the Firm Stock set forth opposite that Underwriter’s name in Schedule 1 hereto. Each Underwriter shall

be obligated to purchase from the Company, and from each Selling Stockholder, that number of shares of the Firm Stock that represent the same proportion of the number of shares of the Firm Stock to be sold by the Company and by each Selling Stockholder as the number of shares of the Firm Stock set forth opposite the name of such Underwriter in Schedule 1 represents of the total number of shares of the Firm Stock to be purchased by all of the Underwriters pursuant to this Agreement. The respective purchase obligations of the Underwriters with respect to the Firm Stock shall be rounded among the Underwriters to avoid fractional shares, as the Representatives may determine.

In addition, the Company and the Selling Stockholders identified in Schedule 2 hereto each grant to the Underwriters, severally and not jointly, an option to purchase up to 1,425,098 shares, in the case of the Company, and the number of shares of Option Stock set forth opposite such Selling Stockholder’s name in Schedule 2 hereto, in the case of the Selling Stockholders. Such option is exercisable in the event that the Underwriters sell more shares of Common Stock than the number of Firm Stock in the offering and as set forth in Section 5 hereof. Any such election to purchase Option Stock shall be made first with respect to the shares proposed to be sold by the Selling Stockholders up to the maximum number of shares of Option Stock proposed to be sold by all Selling Stockholders (on a pro rata basis based on the maximum number of shares of Option Stock to be sold by each Selling Stockholder as set forth in Schedule 2 hereto) prior to purchasing any shares of Option Stock from the Company. Each Underwriter agrees, severally and not jointly, to purchase the number of shares of Option Stock (subject to such adjustments to eliminate fractional shares as the Representatives may determine) that bears the same proportion to the total number of shares of Option Stock to be sold on such Delivery Date as the number of shares of Firm Stock set forth in Schedule 1 hereto opposite the name of such Underwriter bears to the total number of shares of Firm Stock.

The price of both the Firm Stock and any Option Stock purchased by the Underwriters shall be $[·] per share.

The Company and the Selling Stockholders shall not be obligated to deliver any of the Firm Stock or Option Stock to be delivered on the applicable Delivery Date, except upon payment for all such Stock to be purchased on such Delivery Date as provided herein.

4. Offering of Stock by the Underwriters. Upon authorization by the Representatives of the release of the Firm Stock, the several Underwriters propose to offer the Firm Stock for sale upon the terms and conditions to be set forth in the Prospectus.

It is understood that approximately 500,000 shares of the Firm Stock (the “Directed Shares”) will initially be reserved by the several Underwriters for offer and sale upon the terms and conditions to be set forth in the most recent Preliminary Prospectus and in accordance with the rules and regulations of FINRA to persons having business relationships with the Company and its subsidiaries or affiliates who have heretofore delivered to Barclays Capital Inc. offers or indications of interest to purchase shares of Firm Stock in form satisfactory to Barclays Capital Inc. (such program, the “Directed Share Program” and such persons delivering such offers or indications of interest, the “Directed Share Participants”) and that any allocation of such Firm Stock among the Directed Share Participants will be made in accordance with timely directions received by Barclays Capital Inc. from the Company; provided that under

no circumstances will Barclays Capital Inc. or any Underwriter be liable to the Company or to any Directed Share Participant for any action taken or omitted in good faith in connection with such Directed Share Program. It is further understood that any Directed Shares not affirmatively reconfirmed for purchase by any Directed Share Participant by [9]:00 A.M., New York City time, on the first business day following the date hereof or otherwise are not purchased by Directed Share Participants will be offered by the Underwriters to the public upon the terms and conditions set forth in the Prospectus.

The Company agrees to pay all fees and disbursements incurred by the Underwriters in connection with the Directed Share Program and any stamp duties or other taxes incurred by the Underwriters in connection with the Directed Share Program.

5. Delivery of and Payment for the Stock. Delivery of and payment for the Firm Stock shall be made at 10:00 A.M., New York City time, on the [fourth] full business day following the date of this Agreement or at such other date or place as shall be determined by agreement between the Representatives and the Company. This date and time are sometimes referred to as the “Initial Delivery Date.” Delivery of the Firm Stock shall be made to the Representatives for the account of each Underwriter against payment by the several Underwriters through the Representatives and of the respective aggregate purchase prices of the Firm Stock being sold by the Company and the Selling Stockholders to or upon the order of the Company and the Selling Stockholders of the purchase price by wire transfer in immediately available funds to the accounts specified by the Company and the Selling Stockholders. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. The Company shall deliver the Firm Stock through the facilities of DTC unless the Representatives shall otherwise instruct.

The option granted in Section 3 will expire 30 days after the date of this Agreement and may be exercised in whole or from time to time in part by written notice being given to the Company and the Selling Stockholders by the Representatives; provided that if such date falls on a day that is not a business day, the options granted in Section 3 will expire on the next succeeding business day. Such notice shall set forth the aggregate number of shares of Option Stock as to which the options are being exercised, the names and denominations in which the shares of Option Stock are to be registered and the date and time, as determined by the Representatives, when the shares of Option Stock are to be delivered; provided, however, that this date and time shall not be earlier than the Initial Delivery Date nor earlier than the second business day after the date on which the option shall have been exercised nor later than the fifth business day after the date on which the option shall have been exercised. Each date and time the shares of Option Stock are delivered is sometimes referred to as an “Option Stock Delivery Date,” and the Initial Delivery Date and any Option Stock Delivery Date are sometimes each referred to as a “Delivery Date.”

Delivery of the Option Stock by the Selling Stockholders and payment for the Option Stock by the several Underwriters through the Representatives shall be made at 10:00 A.M., New York City time, on the date specified in the corresponding notice described in the preceding paragraph or at such other date or place as shall be determined by agreement among the Representatives, the Selling Stockholders and the Company. On the Option Stock Delivery Date, the Selling Stockholders shall deliver or cause to be delivered the Option Stock to

the Representatives for the account of each Underwriter against payment by the several Underwriters through the Representatives and of the respective aggregate purchase prices of the Option Stock being sold by the Selling Stockholders to or upon the order of the Selling Stockholders of the purchase price by wire transfer in immediately available funds to the accounts specified by the Selling Stockholders. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. The Selling Stockholders shall deliver the Option Stock through the facilities of DTC unless the Representatives shall otherwise instruct.

10. Indemnification and Contribution.

(a) The Company shall indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or

alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) used or referred to by any Underwriter, (D) any “road show” (as defined in Rule 433 of the Rules and Regulations) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”) or (E) any Blue Sky application or other document prepared or executed by the Company (or based upon any written information furnished by the Company for use therein) specifically for the purpose of qualifying any or all of the Stock under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus, in light of the circumstances under which such statements were made), and shall reimburse each Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show or any Blue Sky Application, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 10(f). The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter or to any director, officer, employee or controlling person of that Underwriter.

(b) The Selling Stockholders, severally in proportion to the number of shares of Stock to be sold by each of them hereunder, shall indemnify and hold harmless each Underwriter, its directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing

Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show, any Blue Sky Application or any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations), prepared by or on behalf of the Selling Stockholder or used or referred to by the Selling Stockholder in connection with the offering of the Stock in violation of Section 7(b) (a “Selling Stockholder Free Writing Prospectus”) or (ii) the omission or alleged omission to state in any Preliminary Prospectus, Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show, any Blue Sky Application or any Selling Stockholder Free Writing Prospectus, any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus, in light of the circumstances under which such statements were made), and shall reimburse each Underwriter, its directors, officers and employees and each such controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, its directors, officers and employees or controlling persons in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided that the indemnification provided for in clauses (i) and (ii) of this Section 10(b) only applies to the Selling Stockholder Information contained in or omitted from any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show, any Blue Sky Application or any Selling Stockholder Free Writing Prospectus. The liability of each Selling Stockholder under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the net proceeds (before deducting expenses) from the offering of the shares of the Stock purchased under this Agreement received by such Selling Stockholder. The foregoing indemnity agreement is in addition to any liability that the Selling Stockholders may otherwise have to any Underwriter or any officer, employee or controlling person of that Underwriter.

(c) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each Selling Stockholder, their respective directors, officers and employees, and each person, if any, who controls the Company or such Selling Stockholder within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, such Selling Stockholder or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any Preliminary

Prospectus, the Prospectus or any Issuer Free Writing Prospectus, in light of the circumstances under which such statements were made), but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 10(f). The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Company, such Selling Stockholder or any such director, officer, employee or controlling person.

(d) Promptly after receipt by an indemnified party under this Section 10 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 10 except to the extent it has been materially prejudiced by such failure. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 10 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 10 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to them that are different from, additional to or in conflict with those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. In no event shall the indemnifying party be liable for fees and expenses of more than one counsel (in addition to local counsel) separate from its own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld, conditioned or delayed), 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 includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld, conditioned or delayed), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action (for which timely notice was provided to the indemnifying party in accordance with this Section 10(d)), the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(e) If the indemnification provided for in this Section 10 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 10(a), 10(b), 10(c) or 10(g) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and each of the Selling Stockholders, on the one hand, and the Underwriters, on the other, from the offering of the Stock 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 and each of the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company and each of the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company and each of the Selling Stockholders, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the shares of the Stock purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Stockholders or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 10(e) were to be 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 into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss,

claim, damage or liability, or action in respect thereof, referred to above in this Section 10(e) shall be deemed to include, for purposes of this Section 10(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10(e), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Stock underwritten by it exceeds the amount of any damages that such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 10(e), no Selling Stockholder shall be required to contribute any amount in excess of the amount by which such Selling Stockholder’s net proceeds (before deducting expenses) received by it from the offering of the shares of the Stock purchased under the Agreement exceeds the amount of any damages that such Selling Stockholder has otherwise paid or become liable to pay by reason of any 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 Underwriters’ obligations to contribute as provided in this Section 10(e) are several in proportion to their respective underwriting obligations and not joint. The Selling Stockholders’ obligations to contribute as provided in this Section 10(e) are several in proportion to the number of shares of Stock to be sold by each of them hereunder.

(f) The Underwriters severally confirm and the Company and each Selling Stockholder acknowledges and agrees that (i) the statements regarding delivery of shares by the Underwriters set forth on the cover page of, (ii) the first two sentences of the second paragraph appearing under the caption “Underwriting—Commissions and Expenses” in, (iii) the second sentence of the third paragraph appearing under the caption “Underwriting—Lock-Up Agreements” in, (iv) the third sentence of the first paragraph appearing under the caption “Underwriting—Offering Price Determination” in, (v) the first paragraph appearing under the caption “Underwriting—Stabilization, Short Positions and Penalty Bids” in, (vi) the third and fourth sentences of the first paragraph appearing under the caption “Underwriting—Electronic Distribution” in, and (vii) the paragraph appearing under the caption “Underwriting—Discretionary Sales” in, the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show.

(g) The Company shall indemnify and hold harmless Barclays Capital Inc. (including its directors, officers and employees) and each person, if any, who controls Barclays Capital Inc. within the meaning of Section 15 of the Securities Act (“Barclays Capital Entities”), from and against any loss, claim, damage or liability or any action in respect thereof to which any of the Barclays Capital Entities may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action (i) arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the approval of the Company

for distribution to Directed Share Participants in connection with the Directed Share Program 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, (ii) arises out of, or is based upon, the failure of the Directed Share Participant to pay for and accept delivery of Directed Shares that the Directed Share Participant agreed to purchase or (iii) is otherwise related to the Directed Share Program; provided that the Company shall not be liable under this clause (iii) for any loss, claim, damage, liability or action that is determined in a final judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Barclays Capital Entities. The Company shall reimburse the Barclays Capital Entities promptly upon demand for any legal or other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred.

11. Defaulting Underwriters. If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Stock that the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of shares of the Firm Stock set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of shares of the Firm Stock set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Stock on such Delivery Date if the total number of shares of the Stock that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of shares of the Stock to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of shares of the Stock that it agreed to purchase on such Delivery Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Stock to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the shares that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to any Option Stock Delivery Date, the obligation of the Underwriters to purchase, and of the Company to sell, the Option Stock) shall terminate without liability on the part of any non-defaulting Underwriter or the Company or the Selling Stockholders, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 8 and 13. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 11, purchases Stock that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company and the Selling Stockholders for damages caused by its default. If other Underwriters are obligated or agree to purchase the Stock of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the reasonable opinion of

counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

12. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company and the Selling Stockholders prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Sections 9(l), 9(m) and 9(n) shall have occurred or if the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement.

13. Reimbursement of Underwriters’ Expenses. If (a) the Company or any Selling Stockholder shall fail to tender the Stock for delivery to the Underwriters for any reason or (b) the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement (otherwise than pursuant to Section 11), the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Stock, and upon demand the Company shall pay the full amount thereof to the Representatives.

The Company and the Selling Stockholders acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

15. No Fiduciary Duty. The Company and the Selling Stockholders acknowledge and agree that in connection with this offering, sale of the Stock or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company, Selling Stockholders and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to either the Company or the Selling Stockholders, including, without limitation, with respect to the determination of the public offering price of the Stock, and such relationship

between the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company or Selling Stockholders shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company and the Selling Stockholders. The Company and the Selling Stockholders hereby waive any claims that the Company or the Selling Stockholders may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

As Representatives of the several

Underwriters named in Schedule 1 to the Underwriting Agreement

Ladies and Gentlemen:

The undersigned understands that you and certain other firms (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriters of shares (the “Stock”) of Common Stock, par value $0.001 per share (the “Common Stock”), of Thermon Group Holdings, Inc., a Delaware corporation (the “Company”), and that the Underwriters propose to reoffer the Stock to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Barclays Capital Inc. and Jefferies & Company, Inc., on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could reasonably be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock (including, without limitation, shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and shares of Common Stock that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Common Stock (other than the Stock to the extent applicable), (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock or any other securities of the Company or (4) publicly disclose the intention to do any of the foregoing, in each case, for a period commencing on the date hereof and

ending on the 180th day after the date of the Prospectus relating to the Offering (such 180-day period, the “Lock-Up Period”). For purposes of this Lock-Up Letter Agreement, “Prospectus” shall refer to the final prospectus of the Company relating to the Offering filed with the SEC pursuant to Rule 424(b).

Notwithstanding the foregoing, if (1) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed by this Lock-Up Letter Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or the occurrence of the material event, unless Barclays Capital Inc. and Jefferies & Company, Inc., on behalf of the Underwriters, waive such extension in writing. The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Letter Agreement during the period from the date of this Lock-Up Letter Agreement to and including the 34th day following the expiration of the Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as such may have been extended pursuant to this paragraph) has expired.

Notwithstanding anything to the contrary contained herein, the foregoing restrictions shall not apply to (i) bona fide gifts, sales, transfers or other dispositions of shares of any class of the Company’s capital stock or securities convertible into or exchangeable for any class of the Company’s capital stock, in each case that are made between and among the undersigned and members of the undersigned’s family or affiliates of the undersigned, including its partners (if a partnership), members (if a limited liability company), stockholders (if a corporation) or trusts for the direct or indirect benefit of the undersigned or members of the undersigned’s family; (ii) transfers by will or intestacy; (iii) the exercise of an option to purchase shares of Common Stock granted on or prior to the date of the Prospectus under an equity incentive plan of the Company described in the Prospectus, provided that this Lock-Up Letter Agreement shall apply to any shares of Common Stock issued pursuant to such exercise; (iv) transactions relating to shares of Common Stock or other securities of the Company acquired in open market transactions, block purchases or pursuant to a public offering, in each case occurring after the consummation of the Offering; or (v) the sale of the Stock to the Underwriters pursuant to the Underwriting Agreement; provided that it shall be a condition to any such sale, transfer, exercise or other disposition or transaction, as applicable, that (A) with respect to the foregoing clauses (i) and (ii), the transferee/donee agrees to be bound by the terms of this Lock-Up Letter Agreement (including, without limitation, the restrictions set forth in the preceding sentence) to the same extent as if the transferee/donee were a party hereto; (B) with respect to the foregoing clauses (i), (ii), (iii) and (iv), no filing by any party (donor, donee, transferor, transferee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), reporting a

3

reduction in beneficial ownership of shares of Common Stock shall be required or shall be voluntarily made during the Lock-Up Period in connection with such transfer, distribution or transaction; and (C) with respect to the foregoing clauses (i), (ii), (iii) and (iv), no party shall voluntarily make any public announcement of a reduction in beneficial ownership of shares of Common Stock in connection with any transfer, disposition or transaction during the Lock-Up Period.

Nothing in this Lock-Up Letter Agreement shall prevent the establishment by the undersigned of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act; provided that it shall be a condition to the establishment of any such Plan that no sales of the Company’s capital stock shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period; and provided, further, such a Plan may only be established if no public announcement of the establishment or the existence thereof, and no filing with SEC or any other regulatory authority shall be required or shall be made voluntarily by the undersigned, the Company or any other person, prior to the expiration of the Lock-Up Period.

In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, (i) if the Company notifies the Underwriters that it does not intend to proceed with the Offering, (ii) if the Underwriting Agreement does not become effective, (iii) if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Stock, or (iv) if the Company’s Registration Statement on Form S-1 of which the Prospectus forms a part is withdrawn, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Company and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

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

[Signature page follows]

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

Very truly yours,
