(“Rule 424(b)”). The Basic Prospectus, any preliminary prospectus and the final prospectus supplement, in the form first furnished or made available to the Underwriter for use in connection with the offering of the Shares, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, are collectively referred to herein as the “Prospectus,” and the term “preliminary prospectus” means any preliminary form of the Prospectus.

(a) The Company meets the requirements for use of Form S-3 under the Securities Act.

The Registration Statement has become effective under the Securities Act. No stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act, no order preventing or suspending the use of the Basic Prospectus or the Prospectus has been issued and no proceedings for any of those purposes have been instituted or are pending or, to the Company’s knowledge, contemplated. The Company has complied with each request (if any) from the Commission for additional information. The Registration Statement, at the time of its effectiveness and at each deemed effective date with respect to the Underwriter pursuant to Rule 430B(f)(2) under the Securities Act Regulations, complied in all material respects with the requirements of the Securities Act and the Securities Act Regulations. The Basic Prospectus (filed as part of the Registration Statement as originally filed or as part of any amendment thereto), at the time it was filed, complied in all material respects with the Securities Act Regulations and the Basic Prospectus and the Prospectus delivered by the Company to the Underwriter for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR or IDEA, except to the extent permitted by Regulation S-T. The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, when they became effective or at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission under the Exchange Act (the “Exchange Act Regulations”).

(b) Neither the Registration Statement nor any amendment thereto, at its effective date or at the Closing Date (as defined in Section 5), contained, contains or will contain an untrue statement of a material fact or omitted, omits or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Time of Sale Prospectus and the Prospectus, at the time the Registration Statement became effective or when such documents incorporated by reference were filed with the Commission, as the case may be, when read together with the other information in the Registration Statement, the Time of Sale Prospectus or the Prospectus, as the case may be, did not and 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, except that the representations and warranties set forth in this paragraph do not apply to statements in or omissions from the Registration Statement, the Time of Sale Prospectus or the Prospectus (or any amendments or supplements thereto) based upon and in conformity 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 information described as such in Section 10(c) hereof.

(c) No Issuer Free Writing Prospectus conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein, and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of the Securities Act and Securities Act Regulations. Except for the free writing prospectuses, if any, identified in Schedule II hereto forming part of the Time of Sale Prospectus, and electronic road shows, if any, each furnished to the Underwriter before first use, the Company has not prepared, used or referred to, and will not, without the Underwriter’s prior consent, prepare, use or refer to, any free writing prospectus. Any offer that is a written communication relating to the Shares made prior to the initial filing of the Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c) of the Securities Act Regulations) has been filed with the Commission in accordance with the exemption provided by Rule 163 under the Securities Act Regulations (“Rule 163”) and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the Securities Act provided by Rule 163.

(f) No filing with, or consent, approval, authorization, order, registration, qualification or decree of any arbitrator, court, governmental body, regulatory body, administrative agency or other authority, body or agency, domestic or foreign, is necessary or required for the performance by the Selling Shareholder of its obligations hereunder, or in connection with the sale and delivery of the Shares hereunder or the consummation of the transactions contemplated by this Agreement, except such as have been already obtained or as may be required under the Securities Act and the Securities Act Regulations, the rules of the New York Stock Exchange or state securities laws.

(a) The Company will furnish to the Underwriter in New York City, without charge, a signed copy of the Registration Statement (including exhibits thereto and documents incorporated by reference therein) and will deliver to the Underwriter during the period mentioned in Section 7(f) below, as many copies of the Time of Sale Prospectus, the Prospectus and any supplements and amendments thereto or to the Registration Statement as the Underwriter may reasonably request.

(b) Before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus, the Company will furnish to the Underwriter a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the Underwriter reasonably objects.

(c) The Company will furnish to the Underwriter a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not to use or refer to any proposed free writing prospectus to which the Underwriter reasonably objects.

(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.

(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) the information contained in the eleventh, twelfth and thirteenth paragraphs under the caption “Underwriting” relating to stabilization transactions and (ii) the information in the fourteenth 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.

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

17. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriter shall be delivered, mailed or sent to the care of Barclays Capital Inc., 745 Seventh Avenue, New York, New York 10019, Attention: Syndicate Registration (Fax: (646) ###-###-####), with a copy, in the case of any notice

New York, New York 10019

Booz Allen Hamilton Holding Corporation

Ladies and Gentlemen:

We have acted as special counsel to Booz Allen Hamilton Holding Corporation, a Delaware corporation (the “Company”), in connection with the sale today by Explorer Coinvest LLC (the “Selling Stockholder”) of 16,660,000 shares (the “Securities”) of the Company’s Class A Common Stock, par value $0.01 per share (the “Common Stock”), to you (the “Underwriter”) pursuant to the Underwriting Agreement, dated December 1, 2016, (the “Underwriting Agreement”), among the Company, the Selling Stockholder and the Underwriter. We are delivering this letter to you pursuant to Section 6(c) of the Underwriting Agreement.

As used herein, the following terms shall have the following meanings: The term “DGCL” means the General Corporation Law of the State of Delaware, as currently in effect. The term “Material Adverse Effect” means a material adverse effect on the business, operations, property or financial condition of the Company and its subsidiaries taken as a whole. The term “1940 Act” means the Investment Company Act of 1940, as amended. The term “Time of Sale Prospectus” means the base prospectus, dated November 30, 2016 (the “Base Prospectus”), filed with the Securities and Exchange Commission (the “SEC”) as part of the Company’s automatic shelf registration statement on Form S-3 (Registration No. 333-214855), and the free writing prospectus, dated December 1, 2016, as filed by the Company with the SEC on December 1, 2016, relating to the Securities, in the form filed with the Securities and Exchange Commission pursuant to Rule 433 under the Securities Act of 1933, as amended (the “Securities Act”). The term “Prospectus” means the Base Prospectus, as supplemented by, and together with, the prospectus supplement, dated December 1, 2016, relating to the Securities, in the form filed with the SEC pursuant to Rule 424(b) under the Securities Act.

In rendering the opinions expressed below, (a) we have examined and relied on the originals, or copies certified or otherwise identified to our

A-1 – 1

satisfaction, of such agreements, documents and records of the Company and its subsidiaries and such other instruments and certificates of public officials, officers and representatives of the Company and its subsidiaries and others as we have deemed necessary or appropriate for the purposes of such opinions, (b) we have examined and relied as to factual matters upon, and have assumed the accuracy of, the statements made in the certificates of public officials, officers and representatives of the Company and its subsidiaries and others delivered to us and the representations and warranties contained in or made pursuant to the Underwriting Agreement and (c) we have made such investigations of law as we have deemed necessary or appropriate as a basis for such opinions. In rendering the opinions expressed below, we have assumed, with your permission, without independent investigation or inquiry, (i) the authenticity and completeness of all documents submitted to us as originals, (ii) the genuineness of all signatures on all documents that we examined, (iii) the conformity to authentic originals and completeness of documents submitted to us as certified, conformed or reproduction copies and (iv) the legal capacity of all natural persons executing documents.

Based upon and subject to the foregoing and the assumptions, qualifications and limitations hereinafter set forth, we are of the opinion that:

1.	The Company (a) is validly existing and in good standing under the laws of the State of Delaware and (b) has the corporate power and authority to conduct its business as described in the Time of Sale Prospectus and the Prospectus.

2.	The Company has the corporate power and authority to execute, deliver and perform its obligations under the Underwriting Agreement.

3.	The Underwriting Agreement has been duly authorized, executed and delivered by or on behalf of the Company.

4.	The authorized capital stock of the Company is as stated in the Prospectus under the heading “Description of Capital Stock.”

5.	The Securities being sold to the Underwriter today have been duly authorized and are validly issued, fully paid and non-assessable.

6.	The statements in the Time of Sale Prospectus and the Prospectus under the heading “Description of Capital Stock – Common Stock,” insofar as such statements purport to summarize certain terms of the Common Stock, are accurate in all material respects.

7.	No consent or authorization of, approval by, notice to or filing with any United States Federal, New York State or (insofar as the DGCL is concerned) Delaware governmental authority is required under United States Federal,

A-1 – 2

New York State or the DGCL to be obtained or made on or prior to the date hereof by the Company for the execution and delivery by the Company of the Underwriting Agreement, except for any consents, authorizations, approvals, notices and filings that have been obtained or made and are in full force and effect and those consents, authorizations, approvals, notices and filings that, individually or in the aggregate, if not made, obtained or done would not to our knowledge have a Material Adverse Effect; provided that we express no opinion in this paragraph 7 with respect to United States Federal or state securities laws.

The execution and delivery by the Company of the Underwriting Agreement did not violate (a) the Company’s Third Amended and Restated Certificate of Incorporation or Second Amended and Restated By-Laws, (b) to our knowledge, any United States Federal or New York State law, rule or regulation known to us to be applicable to the Company or the DGCL, (c) any existing judgment, order or decree known to us of any United States Federal, New York State or (insofar as the DGCL is concerned) Delaware court or other governmental authority known by us to be binding upon the Company, or (d) any contract listed in Schedule A hereto to which the Company is a party; except, in the case of clauses (b), (c) and (d), for such violations that to our knowledge would not have a Material Adverse Effect; provided that we express no opinion in this paragraph 8 with respect to United States Federal or state securities laws.

The Company is not and, on the date hereof after giving effect to the offering and sale of the Securities by the Selling Stockholder in the manner contemplated by the Underwriting Agreement and the Prospectus, will not be, required to be registered as an “investment company” (as defined in the 1940 Act) under the 1940 Act.

10.

Subject to the assumptions, qualifications and limitations set forth in the Prospectus, the statements of United States Federal income tax law under the heading “Material U.S. Federal Tax Considerations for Non-U.S. Holders” in the Prospectus, as they relate to the Securities, are accurate in all material respects.

11.	The sale today by the Selling Stockholder of the Securities in accordance with the terms of the Underwriting Agreement will not violate the Company’s Third Amended and Restated Certificate of Incorporation or Second Amended and Restated By-laws.

In rendering the opinion in paragraph 8, we do not express any opinion as to any computation of any financial ratio, covenant or measurement under any contract listed in Schedule A hereto, or as to compliance with any financial ratio, covenant or measurement contained in any contract listed in Schedule A hereto.

A-1 – 3

For purposes of the opinion set forth in paragraph 8 as to any judgment, order or decree referred to therein, we have only endeavored, to the extent we have believed necessary, to determine from lawyers currently in our firm who have performed substantive legal services for the Company whether such services involved substantive attention in the form of legal representation concerning any judgment, order or decree of the nature referred to in such paragraph 8. We have not made any other review, search or investigation, whether of any public files or records or otherwise, with respect to such opinion.

We express no opinion as to the laws of any jurisdiction other than the laws of the State of New York, the DGCL and the Federal laws of the United States of America, as currently in effect, in each case that in our experience are normally applicable to transactions of the type contemplated by the Underwriting Agreement without regard to the particular nature of the business conducted by the Company.

The opinions expressed herein are solely for your benefit and, without our prior written consent, neither our opinions nor this opinion letter may be disclosed to or relied upon by any other person. This opinion letter is limited to, and no opinion is implied or may be inferred beyond, the matters expressly stated herein. The opinions expressed herein are rendered only as of the date hereof, and we assume no responsibility to advise you of facts, circumstances, changes in law, or other events or developments that hereafter may occur or be brought to our attention and that may alter, affect or modify the opinions expressed herein.

Very truly yours,

Ladies and Gentlemen:

In so acting, we have reviewed the shelf registration statement on Form S-3 (Registration No. 333-214855), of the Company filed with the Securities and Exchange Commission (the “SEC”) pursuant to the Securities Act of 1933, as amended (the “1933 Act”), the Time of Sale Information (as defined below) and the prospectus supplement, dated December 1, 2016 (the “Prospectus Supplement”), relating to the Securities, in the form filed with the SEC pursuant to Rule 424(b) under the 1933 Act. As used herein, the term “Registration Statement” means such registration statement on the date such registration statement is deemed to be effective pursuant to Rule 430B under the 1933 Act for purposes of liability under Section 11 of the 1933 Act of the Company and the Underwriter (which for purposes hereof, is December 1, 2016 (the “Effective Date”)), including the information deemed to be a part of such registration statement as of the Effective Date pursuant to Rule 430B under the 1933 Act. The term “Base Prospectus” means the base prospectus dated November 30, 2016, filed with the SEC as part of the Registration Statement. The term “Prospectus Supplement” means the prospectus supplement, dated December 1, 2016, relating to the Securities, in the form filed with the SEC pursuant to Rule 424(b) under the 1933 Act. The term “Free Writing Prospectus” means the free writing prospectus, dated December 1, 2016, as filed by the Company with the SEC on December 1, 2016, pursuant to Rule 433 under the 1933 Act. The term

“Time of Sale Information” means, collectively, the Base Prospectus, the Free Writing Prospectus, the price to the public and the number of Securities on the cover pages of the Prospectus Supplement. The term “Prospectus” means the Base Prospectus as supplemented by, and together with, the Prospectus Supplement. Any reference herein to the Registration Statement, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein.

We have reviewed and discussed the contents of the Registration Statement, the Time of Sale Information and the Prospectus with certain officers and employees of the Company and its internal counsel, the Underwriter and their counsel and representatives of the Company’s independent accountants. We have not ourselves checked the accuracy, completeness or fairness of, or otherwise verified, and are not passing upon and assume no responsibility for the accuracy, completeness or fairness of, the statements contained in the Registration Statement, the Time of Sale Information, the Prospectus or the documents incorporated by reference in any of the foregoing, and have made no independent check or verification thereof. We have assumed the accuracy of the representations and warranties of the Company set forth in Section 1(d) of the Underwriting Agreement as to its status as a “well known seasoned issuer” as defined in Rule 405 under the 1933 Act.

On the basis of the foregoing, we advise you as follows:

(i) The Registration Statement, as of the Effective Date, and the Prospectus, as of the date of the Prospectus Supplement, appeared to us on their face to be appropriately responsive in all material respects to the requirements as to form of the 1933 Act and the applicable rules and regulations of the SEC thereunder; except that we express no view as to (a) the documents incorporated by reference in the Registration Statement or the Prospectus; (b) the financial statements, the related notes and schedules, and other financial and accounting data or information contained in or omitted from the Registration Statement or the Prospectus; (c) the report of management’s assessment of the effectiveness of internal control over financial reporting or the auditor’s attestation report thereon contained in the Registration Statement or the Prospectus; or (d) Regulation S-T.

(ii) No facts have come to our attention that have caused us to believe that (a) the Registration Statement, as of the Effective Date, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (b) the Time of Sale Information, as of 6:23 a.m. New York City time on December 1, 2016, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (c) the Prospectus, as of the date of the Prospectus Supplement and as of the date and time of the delivery of this letter, contained or contains any untrue statement of a material fact or omitted or

A-2 – 2

omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that in each case we express no belief as to (1) the financial statements, the related notes and schedules, and other financial and accounting data or information contained in or omitted from the Registration Statement, the Time of Sale Information or the Prospectus; or (2) the report of management’s assessment of the effectiveness of internal control over financial reporting or the auditor’s attestation report thereon contained in the Registration Statement, the Time of Sale Information or the Prospectus.

(iii) The Registration Statement became effective upon filing under the 1933 Act, and, based exclusively on the telephone advice of the staff of the SEC and the notice of effectiveness of the Registration Statement posted on the SEC’s EDGAR database, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for such purpose are pending before the SEC.

This letter is solely for your benefit and, without our prior written consent, neither our beliefs nor this letter may be disclosed to or relied upon by any other person. This letter is limited to the matters stated herein and no views are implied or may be inferred beyond the matters expressly stated herein. The beliefs expressed herein are rendered only as of the date hereof, and we assume no responsibility to advise you of facts, circumstances, changes in law or other events or developments that hereafter may occur or be brought to our attention and that may alter, affect or modify the beliefs expressed herein.

Ladies and Gentlemen:

We have acted as special counsel to Explorer Coinvest LLC, a Delaware limited liability company (the “Selling Stockholder”), in connection with the sale by the Selling Stockholder on this day of 16,660,000 shares (the “Securities”) of Class A Common Stock, par value $0.01 per share (the “Common Stock”), of Booz Allen Hamilton Holding Corporation (the “Company”) to you (the “Underwriter”) pursuant to the Underwriting Agreement, dated December 1, 2016, (the “Underwriting Agreement”), among the Company, the Selling Stockholder and the Underwriter. We are delivering this letter to you pursuant to Section 6(c) of the Underwriting Agreement.

As used herein, the following terms shall have the following meanings: The term “Applicable Laws” means the Federal laws of the United States, the laws of the State of New York and the statutory provisions of the Delaware Limited Liability Company Act, excluding other Delaware law (including common law), in each case as currently in effect, that in our experience are normally applicable to transactions of the type contemplated by the Underwriting Agreement (other than United States Federal or state securities laws, antifraud laws, fraudulent conveyance or transfer laws and tax laws) without regard to the particular nature of the business conducted by the Selling Stockholder and without our having made any review, search or investigation as to the applicability of any specific law, rule or regulation applicable to the Selling Stockholder. “Governmental Approval” means any consent or authorization of, approval by, notice to or filing with, any United States Federal or New York State court or governmental authority having jurisdiction over the Selling Stockholder under any Applicable Law to be obtained or made by the Selling Stockholder pursuant to any Applicable Law, other than those consents, authorizations, approvals, notices and filings that, if not made, obtained or done, would not to our knowledge have a Material Adverse Effect. “Material Adverse Effect” means a material adverse effect on the ability of the Selling Stockholder to perform its obligations under the Underwriting Agreement. “UCC” means the Uniform Commercial Code as in effect in the State of New York on the date hereof.

A-3 – 1

In rendering the opinions expressed below, (a) we have examined and relied on the originals, or copies certified or otherwise identified to our satisfaction, of such agreements, documents and records of the Selling Stockholder and such other instruments and certificates of public officials, officers and representatives of the Selling Stockholder and others as we have deemed necessary or appropriate for the purposes of such opinions, (b) we have examined and relied as to factual matters upon, and have assumed the accuracy of, the statements made in the certificates of public officials, officers and representatives of the Selling Stockholder and others delivered to us and the representations and warranties contained in or made pursuant to the Underwriting Agreement and (c) we have made such investigations of law as we have deemed necessary or appropriate as a basis for such opinions. In rendering the opinions expressed below, we have assumed, with your permission, without independent investigation or inquiry, (i) the authenticity and completeness of all documents submitted to us as originals, (ii) the genuineness of all signatures on all documents that we examined, (iii) the conformity to authentic originals and completeness of documents submitted to us as certified, conformed or reproduction copies, (iv) the legal capacity of all natural persons executing documents, (v) the power and authority of all parties (other than the Selling Stockholder and the Company) to enter into and perform their respective obligations under the Underwriting Agreement, (vi) that each of the certificate of limited liability company and the limited liability company agreement (collectively, the “Governing Documents”) of the Selling Stockholder is (A) a valid and binding agreement of the parties thereto, enforceable in accordance with the plain meaning of its terms, (B) in full force and effect and (C) the entire agreement of the parties pertaining to the subject matter thereof, (vii) except to the extent expressly set forth in paragraph 2 below and our opinion in respect of the Company dated as of the date hereof, the due authorization, execution and delivery of the Underwriting Agreement by all parties thereto and the validity and binding effect thereof on such parties, (viii) that all parties (other than with respect to the Selling Stockholder to the extent, if any, expressly set forth in the opinions set forth below) to the Underwriting Agreement are duly organized and are validly existing in good standing under the laws of their respective jurisdictions of organization and that all parties to the Underwriting Agreement have complied with all aspects of applicable laws of all jurisdictions in connection with the transactions contemplated by the Underwriting Agreement, (ix) the enforceability of the Underwriting Agreement against all respective parties thereto and (x) that the jurisdiction of The Depository Trust Company, as securities intermediary (“DTC”), for purposes of Article 8 of the UCC, is the State of New York.

A-3 – 2

Based upon and subject to the foregoing and the assumptions, qualifications and limitations hereinafter set forth, we are of the opinion that:

1. The Selling Stockholder has the limited liability company power and authority to execute and deliver and perform its obligations under the Underwriting Agreement.

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 January 30, 2015, among Booz Allen Hamilton Holding Corporation, Explorer Coinvest LLC and certain 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.

A-3 – 3

We express no opinion as to the laws of any jurisdiction other than the Applicable Laws.

Very truly yours,

I am delivering this letter to you pursuant to Section 6(d) of the Underwriting Agreement.

As used herein, the following terms shall have the following meanings: The term “DGCL” means the General Corporation Law of the State of Delaware, as currently in effect. The term “Time of Sale Prospectus” means the base prospectus, dated November 30, 2016 (the “Base Prospectus”) filed with the Securities and Exchange Commission (the “SEC”) as part of the Company’s automatic shelf registration statement on Form S-3 (Registration No. 333-214855) (the “Registration Statement”) and the free writing prospectus, dated December 1, 2016, as filed by the Company with the Commission on December 1, 2016, pursuant to Rule 433 under the Securities Act of 1933, as amended (the “Securities Act”) (the “Free Writing Prospectus”). The term “Prospectus” means the Base Prospectus, as supplemented by, and together with, the prospectus supplement, dated December 1, 2016, relating to the Securities, in the form filed with the SEC pursuant to Rule 424(b) under the Securities Act.

In rendering the opinions expressed below, I, or lawyers on the legal staff of the Company or its subsidiaries working under my supervision, have (a) examined and relied on the originals, or copies certified or otherwise identified to my or their satisfaction, of such agreements, documents and records of the Company and its subsidiaries and such other instruments and certificates of public officials, officers and representatives of the Company and its subsidiaries and others as I have deemed necessary or appropriate for

B – 1

the purposes of such opinions, (b) examined and relied as to factual matters upon, and have assumed the accuracy of, the statements made in the certificates of public officials, officers and representatives of the Company and its subsidiaries and others delivered to me and the representations and warranties contained in or made pursuant to the Underwriting Agreement and (c) made such investigations of law as I have deemed necessary or appropriate as a basis for such opinions.

Based upon and subject to the foregoing and the assumptions, qualifications and limitations hereinafter set forth, I am of the opinion that:

1.	Based solely on certificates from public officials, Booz Allen Hamilton Inc. (a) is validly existing and in good standing under the laws of the State of Delaware and (b) is qualified to do business in the states listed on Schedule A hereto.

2.	Based solely on certificates from public officials, each of Booz Allen Hamilton International, Inc. and Booz Allen Hamilton Engineering Holding Co., LLC is validly existing and in good standing under the laws of the State of Delaware.

Based solely upon a review as of the date hereof of certificates representing the outstanding capital stock of, and transfer records for, the Company’s subsidiaries, all of the outstanding shares of capital stock of the Company’s subsidiaries were owned of record on that date by the Company or a subsidiary of the Company, and were validly issued, fully paid and non-assessable and not subject to preemptive rights arising under the DGCL or their certificate of incorporation or by-laws.

4.	To my knowledge, except as described in the Time of Sale Prospectus and the Prospectus, the Company is not subject to any legal, administrative or judicial proceeding in the United States of America required to be described in the Prospectus by Item 103 of Regulation S-K under the Securities Act.

I express no opinion as to the laws of any jurisdiction other than the DGCL and the Federal laws of the United States of America, as currently in effect, in each case that in my experience are normally applicable to transactions of the type contemplated by the Underwriting Agreement without regard to the particular nature of the business conducted by the Company.

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

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.

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.
