(d)    Each of the Company and the Selling Shareholder agrees that, unless it obtains the Underwriter’s prior written consent, it will not make any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” or a portion thereof, required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the Underwriter will be deemed to have consented to the Issuer Free Writing Prospectuses listed on Schedule II hereto and any “road show that is a written communication” within the meaning of Rule 433(d)(8)(i) that has been reviewed by the Underwriter. Each of the Company and the Selling Shareholder represents that it has treated or agrees that it will treat each such free writing prospectus consented to, or deemed consented to, by the Underwriter as an “issuer free writing prospectus,” as defined in Rule 433, and that it has complied and will comply with the applicable requirements of Rule 433 with respect thereto, including timely filing with the Commission where required, legending and record keeping. 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 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 existing at that subsequent time, not misleading, the Company will promptly notify the Underwriter and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(e)    The Company, subject to Section 3(f), will comply with the requirements of Rule 430B, and will notify the Underwriter promptly, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective or any amendment or supplement to the Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus, including any document incorporated by reference therein or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment or of any order preventing or suspending the use of any preliminary prospectus or the Prospectus, or of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the Securities Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the Securities Act in connection with the offering of the Shares. The Company will affect all filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order, prevention or suspension and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment. The Company

shall pay the required Commission filing fees relating to the Shares within the time required by Rule 456(b)(1)(i) under the Securities Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Securities Act Regulations (including, if applicable, by updating the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b)).

(f)    The Company will comply with the Securities Act, the Securities Act Regulations, the Exchange Act and the Exchange Act Regulations, including with respect to filing all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and Exchange Act Regulations, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and in the Time of Sale Prospectus and the Prospectus. If at any time when a prospectus relating to the Shares is (or, but for the exception afforded by Rule 172 of the Securities Act Regulations (“Rule 172”), would be) required by the Securities Act to be delivered in connection with sales of the Shares, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriter or for the Company, to (i) amend the Registration Statement in order that the Registration Statement will not include 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, (ii) amend or supplement the Time of Sale Prospectus or the Prospectus in order that the Time of Sale Prospectus or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser or (iii) amend the Registration Statement or amend or supplement the Time of Sale Prospectus or the Prospectus, as the case may be, in order to comply with the requirements of the Securities Act or the Securities Act Regulations, the Company will promptly (A) give the Underwriter notice of such event, (B) prepare any amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement, the Time of Sale Prospectus or the Prospectus comply with such requirements and, a reasonable amount of time prior to any proposed filing or use, furnish the Underwriter with copies of any such amendment or supplement and (C) file with the Commission any such amendment or supplement; provided that the Company shall not file or use any such amendment or supplement to which the Underwriter or counsel for the Underwriter shall object. The Company will furnish to the Underwriter such number of copies of such amendment or supplement as the Underwriter may reasonably request.

(g)    To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Underwriter shall reasonably request.

(h)    The Company will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its security holders as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriter the benefits contemplated by, the last paragraph of Section 11(a) of the Securities Act.

10.    Indemnity and Contribution.

The liability of the Selling Shareholder pursuant to this subsection (b) shall not exceed the product of (i) the number of Shares sold by the Selling Shareholder and (ii) the per share net proceeds to the Selling Shareholder as set forth in the Prospectus.

(c)    The Underwriter agrees to indemnify and hold harmless the Company, the Selling Shareholder, 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 the Selling Shareholder 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, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof (including any information deemed to be part thereof pursuant to Rule 430B), any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus (taken together with the Time of Sale Prospectus), any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act (taken together with the Time of Sale Prospectus), or the Prospectus or any amended or thereto, (ii) with respect to the Registration Statement or any amendment or supplement thereto (including any information deemed to be part thereof pursuant to Rule 430B), the 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 (iii) with respect to any preliminary prospectus, the Time of Sale Prospectus, any Issuer Free Writing Prospectus (taken together with the Time of Sale Prospectus), any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act (take together with the Time of Sale Prospectus), the Prospectus or any amendment or supplement thereto, the omission or alleged omission to state therein 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, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and inconformity with written information furnished to the Company by the Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by the Underwriter consists of the following information in the Prospectus furnished on behalf of the Underwriter: (i) concession figure appearing in the first sentence of the fifth paragraph under the caption “Underwriting,” (ii) the information contained in the twelfth, thirteenth and fourteenth paragraphs under the caption “Underwriting” relating to stabilization transactions and (iii) the information in the fifteenth paragraph under the caption “Underwriting” relating to electronic offer, sale and distribution of shares.”

(d)    In case any 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 mutually 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 firm (in addition to any local counsel) for the Underwriter and all persons, if any, who control the Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of the Underwriter within the meaning of Rule 405 of the Securities Act; (ii) the fees and expenses of more than one separate 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 Section 15 of the Securities Act or Section 20 of the Exchange Act and (iii) the fees and expenses of more

than one separate firm (in addition to any local counsel) for the Selling Shareholder and all persons, if any, who control the Selling Shareholder 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 firm for the Underwriter and such control persons of the Underwriter, such firm shall be designated in writing by the Underwriter. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding affected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the 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 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 (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) 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.

(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, claims, damages or liabilities 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, claims, damages or liabilities (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 of the Shares or (ii) if the allocation provided by clause 10(d)(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 10(e)(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, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholder on the one hand and the Underwriter on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the Selling Shareholder and the total underwriting discounts and

commissions received by the Underwriter, in each case as set forth in the Prospectus, bear to the aggregate public offering price of the Shares. The relative fault of the Company and the Selling Shareholder on the one hand and the Underwriter on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Selling Shareholder or by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The liability of the Selling Shareholder pursuant to this subsection (e) shall not exceed the product of (i) the number of Shares sold by the Selling Shareholder and (ii) the per share net proceeds to the Selling Shareholder as set forth in the Prospectus.

(f)    The Company, the Selling Shareholder and the Underwriter agree that it would not be just or equitable if contribution pursuant to Section 10 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 10(e) shall be deemed to include, subject to the limitations set forth above, 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, the Underwriter shall not 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 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 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 which may otherwise be available to any indemnified party at law or in equity.

(g)    The indemnity and contribution provisions contained in this Section 10 and the representations, warranties and other statements of the Company and the Selling Shareholder contained in this Agreement 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 the Underwriter, any person controlling the Underwriter or any affiliate of the Underwriter, the Company, its officers or directors, or any person controlling the Company or the Selling Shareholder or any person controlling the Selling Shareholder and (iii) acceptance of and payment for any of the Shares.

11.    Termination. The Underwriter may terminate this Agreement by notice given to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile

Exchange or the Chicago Board of Trade or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over‑the‑counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States or other relevant jurisdictions shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Underwriter’s judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Underwriter’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.

12.    Effectiveness; Failure to Perform. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If this Agreement shall be terminated by the Underwriter because of any failure or refusal on the part of the Company and/or the Selling Shareholder to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company and/or Selling Shareholder shall be unable to perform its obligations under this Agreement, the Selling Shareholder and the Company will be joint and severally liable to reimburse the Underwriter for all out‑of‑pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by the Underwriter in connection with this Agreement or the offering contemplated hereunder.

13.    Entire Agreement. (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 Shareholder, on the one hand, and the Underwriter, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b)    The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriter has acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriter owes the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriter may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriter arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

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

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

2.    The Underwriting Agreement has been duly authorized, executed and delivered by or on behalf of the Selling Stockholder to the extent (if any) that execution and delivery thereof by or on behalf of such Selling Stockholder is governed by the laws of the State of New York.

3.    The execution and delivery by the Selling Stockholder of the Underwriting Agreement did not, and the sale today by the Selling Stockholder of the Securities in accordance with the terms of the Underwriting Agreement will not, violate (i) its Governing Documents, (ii) the Amended and Restated Stockholders Agreement, dated as of November 8, 2010, among Booz Allen Hamilton Holding Corporation, Explorer Coinvest LLC and each individual stockholder that as of the date hereof is party to the Stockholders Agreement, dated as of July 30, 2008, among Booz Allen Hamilton Holding Corporation and certain of its stockholders, together with any waivers obtained thereunder as of the date hereof or (iii) to our knowledge, any Applicable Law, except in the case of clause (iii) for such violations that would not to our knowledge have a Material Adverse Effect.

4.    No Governmental Approval is required to be obtained or made on or prior to the date hereof for the execution and delivery by the Selling Stockholder of the Underwriting Agreement or the sale today by the Selling Stockholder of the Securities in accordance with the terms of the Underwriting Agreement.

5.    Assuming that the Underwriter acquires its interest in the Securities it has purchased from the Selling Stockholder without notice (within the meaning of Section 8-105 of the UCC) of an adverse claim (as defined in Section 8-102(a)(1) of the UCC), the Underwriter has purchased the Securities delivered on the date hereof to DTC by making payment therefor as provided in the Underwriting Agreement and the Underwriter has had the Securities credited to the securities account or accounts of such Underwriter maintained with DTC in accordance with Section 8-501 of the UCC, the Underwriter will have acquired a security entitlement (as defined in Section 8-102(a)(17) of the UCC) to such Securities purchased by such Underwriter, and no action based on an adverse claim (as defined in Section 8-102(a)

(1) of the UCC) may be asserted against such Underwriter with respect to such security entitlement. The opinions expressed in this paragraph 5 are limited to the effect of Article 8 of the UCC.

The undersigned understands that J.P. Morgan Securities LLC (the “Underwriter”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Booz Allen Hamilton Holding Corporation, a Delaware corporation (the “Company”) and Explorer Coinvest LLC (the “Selling Shareholder”), providing for the secondary offering (“Offering”) by the Underwriter of shares (the “Shares”) of the Class A common stock, par value $0.01 per share, of the Company (the “Common Stock”).

To induce the Underwriter to participate in the Offering, the undersigned hereby agrees that, for so long as the undersigned is an employee or director of the Company or would be required to report a disposition under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), (but in any case for no longer than the restricted period or any extension thereof), without the prior written consent of the Underwriter, the undersigned will not, during the period commencing on the date hereof and ending 45 days (the “restricted period”) after the date of the final prospectus supplement relating to the Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Exchange Act) by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock; or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made during the restricted period in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions, (b) transfers of shares of Common Stock or any security convertible into Common Stock by bona fide gift, will or intestacy, (c) distributions of shares of Common Stock or any security convertible into Common Stock to general or limited partners, members or stockholders of the undersigned and partnerships or limited liability companies for the benefit of the immediate family of the undersigned and the partners and members of which are only the undersigned and the immediate family of the undersigned, (d) distributions of shares of Common Stock or any security convertible

into Common Stock to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (e) dispositions of shares of Common Stock to the Company (A) solely to satisfy tax withholding obligations in connection with the exercise of options to purchase Common Stock, the vesting of restricted shares of Common Stock, or the settling of restricted stock, provided that in the related Form 4 the undersigned notes in a footnote that such transfer was undertaken solely to satisfy tax withholding obligations or (B) in connection with the rights of the Company to cause the undersigned to sell shares of Common Stock in effect on the date hereof, (f) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock, provided that such plan does not provide for the transfer of shares of Common Stock during the restricted period and no filing or other public announcement shall be required or shall be voluntarily made during the restricted period (as the same may be extended as provided herein) by the undersigned or the Company as a result of the establishment of any such plan, (g) the transfer of shares of Common Stock pursuant to a trading plan pursuant to Rule 10b5-1 under the Exchange Act that was in effect as of, and only shares scheduled for sale thereunder on, February 2, 2015, (h) the transfer of shares of Common Stock (but excluding, for the avoidance of doubt, shares of Common Stock directly owned by Explorer Coinvest LLC and its affiliates) in an aggregate amount not to exceed, together with all shares of Common Stock transferred by the Company’s executive officers and directors subject to a “lock-up” in connection with the Offering, 150,000 shares of Common Stock (which aggregate amount shall not be deemed to include transfers of shares of Common Stock by any such directors or executive officers in reliance upon any other clause hereof), (i) cashless exercises of options pursuant to the Company’s Officers’ Rollover Stock Plan or Amended and Restated Equity Incentive Plan, provided that the shares of Common Stock issued to and retained by the undersigned as a result thereof shall be subject to this agreement or (j) transfers of shares of Common Stock or any security convertible into Common Stock to a tax-exempt non-profit organization (but, for the avoidance of doubt, in an aggregate amount not to exceed, together with sales by the undersigned during any 90-day period, the volume permitted to be sold by the undersigned pursuant to Rule 144(e) of the Securities Act of 1933, as amended) and provided that such transfers shall not be voluntarily reported on a Form 4; provided, that in the case of any transfer or distribution pursuant to clause (b), (c) or (d), (1) each donee, distributee, trustee or transferee shall sign and deliver a lock‑up letter substantially in the form of this letter and (2) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the restricted period (other than a Form 5 required to be filed within the 45 calendar days following March 31, 2015 and filed during such 45 calendar day period or thereafter). For the purposes of this agreement, “immediate family” shall include any spouse, or any lineal ancestor or descendent, niece, nephew, adopted child, or sibling of him or her or of such spouse, niece, nephew or adopted child. In addition, the undersigned agrees that, without the prior written consent of the Underwriter, it will not, during the period commencing on the date hereof and ending upon expiration of the restricted period (as the same may be extended as provided herein), make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

Notwithstanding the foregoing, if the Underwriter is unable to publish or distribute research reports on the Company pursuant to Rule 139 under the Securities Act and/or Rule 2711 of the National Association of Securities Dealers, and:

(1)    during the last 17 days of the restricted 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 restricted period, the Company announces that it will release earnings results during the 16‑day period beginning on the last day of the restricted period;

the restrictions imposed by this agreement shall continue to apply until the expiration of the 18‑day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. The Company shall promptly notify you of any earnings release, material news or material event that may give rise to an extension of the 45-day restricted period.

The undersigned shall not engage in any transaction that may be restricted by this agreement during the 34‑day period beginning on the last day of the initial restricted period unless the undersigned requests and receives prior written confirmation from the Company that the restrictions imposed by this agreement have expired.

The undersigned understands that the Company and the Underwriter are relying upon this agreement in proceeding toward consummation of the Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

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 between the Company and the Underwriter.
