(ii)    Notification of Certain Commission Actions. The Company will advise you, promptly after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, including any post-effective amendment thereto, or preventing or suspending the use of any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus or any issuer free writing prospectus, of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and the Company will promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order should be issued.

(A)    Within the time during which a prospectus (assuming the absence of Rule 172) relating to the Securities is required to be delivered under the Act by the Underwriter or dealer, the Company will comply in all material respects with all requirements imposed upon it by the Act, as now and hereafter amended, and by the Rules and Regulations, as from time to time in force, so far as necessary to permit the continuance of sales of or dealings in the Securities as contemplated by the provisions hereof, the Time of Sale Disclosure Package and the Prospectus. If during such period any event occurs as a result of which the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend the Registration Statement or supplement the Prospectus (or if the Prospectus is not yet available to prospective investors, the Time of Sale Disclosure Package) to comply with the Act, the Company promptly will (x) notify you of such untrue statement or omission, (y) amend the Registration Statement or supplement the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) (at the expense of the Company) so as to correct such statement or omission or effect such compliance and (z) notify you when any amendment to the Registration Statement is filed or becomes effective or when any supplement to the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) is filed.

(B)    If at any time following issuance of an issuer free writing prospectus there occurred or occurs an event or development as a result of which such issuer free writing prospectus conflicted or would conflict with the information contained in the Registration Statement, any Preliminary Prospectus or the Prospectus relating to the Securities or 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 prevailing at that subsequent time, not misleading, the Company (x) has promptly notified or promptly will notify the Underwriter of such conflict, untrue statement or omission, (y) has promptly amended or will promptly amend or supplement, at its own expense, such issuer free writing prospectus to eliminate or correct such conflict, untrue statement or omission and (z) has notified or promptly will notify you when such amendment or supplement was or is filed with the Commission to the extent required to be filed by the Rules and Regulations.

(iv)    Blue Sky Qualifications. The Company shall take or cause to be taken all necessary action to qualify the Securities for sale under the securities laws of such domestic United States or foreign jurisdictions as you reasonably designate and to continue such qualifications in effect so long as required for the distribution of the Securities, except that the Company shall not be required in connection therewith to qualify as a foreign corporation or to execute a general consent to service of process in any state.

(vii)    Payment and Reimbursement of Expenses. The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, will pay or cause to be paid (A) all expenses (including transfer taxes allocated to the respective transferees) incurred in connection with the delivery to the Underwriter of the Securities, (B) all expenses and fees (including, without limitation, fees and expenses of the Company’s accountants and counsel but, except as otherwise provided below, not including fees of the Underwriter’s counsel) in connection with the preparation, printing, filing, delivery, and shipping of the Registration Statement (including the financial statements therein and all amendments, schedules, and exhibits thereto), the Securities, each Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, any issuer free writing prospectus and any amendment thereof or supplement thereto, and the printing, delivery, and shipping of this Agreement and other underwriting documents, including Blue Sky Memoranda (covering the states and other applicable jurisdictions), (C) (i) all filing fees and reasonable fees and disbursements of the Underwriter’s counsel incurred in connection with the qualification of the Securities for offering and sale by the Underwriter or by dealers under the securities or blue sky laws of the states and other jurisdictions which you shall designate and (ii) the filing fees and fees and disbursements of Underwriter’s counsel incident to any required review and approval by FINRA of the terms of the sale of the Securities, which fees and disbursements of Underwriter’s counsel in the case of (i) and (ii) shall equal an aggregate amount of $15,000 (excluding applicable filing fees), (D) the fees and expenses and any transfer agent or registrar, (E) listing fees, if any, and (F) all other reasonable costs and expenses of the Company and the Selling Stockholder incident to the performance of its obligations hereunder that are not otherwise specifically provided for herein. If this Agreement is terminated by the Underwriter pursuant to Section 9 hereof or if the sale of the Securities provided for herein is not consummated by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Underwriter’s obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company will reimburse the Underwriter for all out-of-pocket accountable disbursements (including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges) incurred by the Underwriter in connection with their investigation, preparing to market and marketing the Securities or in contemplation of performing their obligations hereunder.

(b)        The Selling Stockholder shall indemnify and hold harmless Underwriter, its affiliates, directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange 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, affiliate, 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 the Registration Statement or in any amendment or supplement thereto, arising out of or caused by any omission or alleged 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 the Time of Sale Disclosure Package, the Prospectus or any Permitted Free Writing Prospectus or any amendment or supplements thereto, or caused by the omission or alleged omission to state therein any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, but in each case only to the extent the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance on and in conformity with the Selling Stockholder Information, and shall reimburse the Underwriter, its affiliates, directors, officers and employees and each such controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, its affiliates, 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 based upon any such untrue statement or omission, or any alleged untrue statement or omission, as such expenses are reasonably incurred provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative expressly for use in the Registration Statement, the Time of Sale Disclosure Package, the Prospectus or any Permitted Free Writing Prospectus (or any amendment or supplement thereto), which information is limited to the information set forth in Section 6(f). The liability of the Selling Stockholder under the indemnity agreement contained in this paragraph shall not exceed an amount equal to the proceeds from the offering of the shares of the Stock purchased under the Agreement received by the Selling Stockholder after any underwriting commissions and discounts, but before expenses.

(c)        The Underwriter shall indemnify and hold harmless the Company, the Selling Stockholder, their respective directors, officers and employees, and each person, if any, who controls the Company or the Selling Stockholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, the Selling Stockholder or any such director, officer, employee or controlling person may become subject, under the 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 the Registration Statement or in any amendment or supplement thereto, arising out of or caused by any omission or alleged 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 the Time of Sale Disclosure Package, the

Prospectus or any Permitted Free Writing Prospectus or any amendment or supplements thereto, or caused by the omission or alleged omission to state therein any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, 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 furnished to the Company by or on behalf of the Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 6(f). The foregoing indemnity agreement is in addition to any liability that the Underwriter may otherwise have to the Company, the Selling Stockholder or any such director, officer, employee or controlling person.

(d)        Promptly after receipt by an indemnified party under this Section 6 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 6, 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 6 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 6. 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 6 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ one single counsel (and local counsel in each applicable jurisdiction) 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 6 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 that there may be legal defenses available to them that are different from or in addition to 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. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, 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. 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 Section 6(a) or (b) hereof, 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 or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(e)        If the indemnification provided for in this Section 6 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 6(a), 6(b) or 6(c) 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 the Selling Stockholder, on the one hand, and the Underwriter, on the other, from the offering of the Securities, 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 the Selling Stockholder, on the one hand, and the Underwriter, 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 the Selling Stockholder, on the one hand, and the Underwriter, 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 Securities purchased under this Agreement (before deducting expenses) received by the Company and the Selling Stockholder, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriter with respect to the shares of the Securities 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 Stockholder or the Underwriter, 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 Stockholder and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 6(e) were to be determined by pro rata allocation 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 6(e) shall be deemed to include, for purposes of this Section 6(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 6(e), in no event shall the Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by the Underwriter with respect to the offering of the Securities exceeds the amount of any damages that the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f)    The Company and the Selling Stockholder acknowledge and agree that the paragraph relating to stabilization by the Underwriter appearing under the caption “Underwriting” in the most recent Preliminary Prospectus and the Prospectus statements constitute the only information furnished in writing

to the Company by or on behalf of the Underwriter specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any issuer free writing prospectus or in any amendment or supplement thereto.

7.        Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Company and the Selling Stockholder herein or in certificates delivered pursuant hereto, and the agreements of the Underwriter, the Company and the Selling Stockholder contained in Section 6 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Underwriter or any controlling person thereof, or the Company and the Selling Stockholder or any of their respective officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Securities to and by the Underwriter hereunder and any termination of this Agreement.

8.        Termination.

You as Underwriter shall have the right to terminate this Agreement by giving notice as hereinafter specified at any time at or prior to the Closing Date, if (i) any condition of the Underwriter’s obligations hereunder is not fulfilled at the Closing Date, (ii) trading on the New York Stock Exchange shall have been wholly suspended, (iii) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NASDAQ Stock Market or New York Stock Exchange, by such Exchange or by order of the Commission or any other Governmental Authority, (iv) a banking moratorium shall have been declared by federal or state authorities, or (v) there shall have occurred any outbreak or escalation of hostilities involving or affecting the United States or there shall have occurred any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Securities. Any such termination shall be without liability of any party to any other party except that the provisions of Section 4(a)(vii) and Section 6 hereof shall at all times be effective.

(b)        Notice of Termination. If you elect to terminate this Agreement as provided in this Section, the Company and the Selling Stockholder shall be notified promptly by you by telephone, confirmed by letter.

9.        Default by the Company.

(a)        Default by the Selling Stockholder. If the Selling Stockholder shall fail at the Closing Date to sell and deliver the number of Securities which it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of the Underwriter or, except as provided in Section 4(a)(vii) and Section 6 hereof, any non‑defaulting party.

(b)        No Relief from Liability. No action taken pursuant to this Section 9 shall relieve the Company or the Selling Stockholder from liability, if any, in respect of such default.

Notwithstanding the foregoing, this Lock-Up Letter Agreement shall not apply (1) to bona fide gifts, (2) to sales or other dispositions of shares of any class of the Company’s capital stock, in each case that are made exclusively between or among the undersigned and members of the undersigned’s family, or affiliates of the undersigned, (3) to one or more trusts of which the sole beneficiaries thereof are the undersigned and/or the undersigned’s immediate family members, (4) in a transaction consummated pursuant to any Rule 10b5-1 sales plan agreement entered into by the undersigned prior to the date hereof (and not in contemplation of the execution hereof) or (5) to transfers to the Company to effect withholding or surrender of any of the undersigned’s shares of Common Stock to the Company to satisfy tax withholding obligations which arise from the exercise or vesting of restricted stock units; provided that to the extent a Form 4 is required to be filed under Section 16 of the Exchange Act in connection with any such exercise, withholding or surrender, such Form 4 will include a description of such transaction (in addition to the applicable transaction code required by such form); provided further, that it shall be a condition to any such transfer pursuant to clauses (1), (2) or (3) above, that (i) 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)
