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 reasonably incurred 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 under 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 such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Shareholders and all persons, if any, who control any Selling Shareholder within the meaning of either such Section, and that all such reasonably incurred 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 and affiliates 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. In the case of any such separate firm for the Selling Shareholders and such control persons of any Selling Shareholders, such firm shall be designated in writing by the Selling Shareholders representing a majority of the shares sold by the Selling Shareholders in the offering contemplated hereby. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, 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 (A) more than 90 days after receipt by such indemnifying party of the aforesaid request and (B) more than 15 days after receipt by such indemnifying party of notice specifying the terms of such settlement and that the indemnified party intends to enter into such settlement and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(e) To the extent the indemnification provided for in Section 11(a), 11(b) or 11(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 11(e)(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 11(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 Shareholders 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 Selling Shareholders bear to the total underwriting discounts and commissions received by the Underwriter. The relative fault of the Company and the Selling Shareholders 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 Shareholders 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 each Selling Shareholder under the contribution agreement contained in this paragraph shall be limited in the aggregate to an amount equal to the aggregate Public Offering Price (net of underwriting discounts and commissions) of the Shares sold by such Selling Shareholder under this Agreement. In addition, the Selling Shareholders’ obligations in this subsection (e) to contribute are several in proportion to their respective sale of Shares and not joint.

(f) The Company, the Selling Shareholders and the Underwriter agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Selling Shareholders or the Underwriter were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(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 11, in no event shall the Underwriter be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to

contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. Notwithstanding anything herein to the contrary, the liability of each Selling Shareholder under the indemnity and contribution agreements contained in this Section 11 shall be limited in the aggregate to an amount equal to the aggregate Public Offering Price (net of underwritten discounts and commissions) of the Shares sold by such Selling Shareholder under this Agreement.

(g) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Company and each 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, any Selling Shareholder or any person controlling any Selling Shareholder, or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

12. Termination. The Underwriter may terminate this Agreement by notice given by the Underwriter to the Company and the Selling Shareholders, 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 NYSE American or the Nasdaq Global Market, (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 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 judgment of the Underwriter, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the judgment of the Underwriter, 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.

13. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

14. Submission to Jurisdiction; Appointment of Agents for Service. (a) Each of the Non-U.S. Selling Shareholders irrevocably submits to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York (the “Specified Courts”) over any suit, action or proceeding arising out of or relating to this Agreement, the Time of Sale Prospectus, the Prospectus, the Registration Statement or the offering of the Shares (each, a “Related Proceeding”). Each of the Non-U.S. Selling Shareholders irrevocably waives, to the fullest extent permitted by law, any

objection which it may now or hereafter have to the laying of venue of any Related Proceeding brought in such a court and any claim that any such Related Proceeding brought in such a court has been brought in an inconvenient forum. To the extent that any of the Non-U.S. Selling Shareholders has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, such Non-U.S. Selling Shareholder irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

(b) Each of the Non-U.S. Selling Shareholders hereby irrevocably appoints ▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇, with offices at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, as its agent for service of process in any Related Proceeding and agrees that service of process in any such Related Proceeding may be made upon it at the office of such agent. Each of the Non-U.S. Selling Shareholders waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto. Each of the Non-U.S. Selling Shareholders represents and warrants that such agent has agreed to act as such Non-U.S. Selling Shareholder’s agent for service of process, and each of the Non-U.S. Selling Shareholders agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect.

15. 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 Shareholders, 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 and the Selling Shareholders acknowledge that in connection with the offering of the Shares: (i) the Underwriter has acted at arm’s length, is not an agent of, and owes no fiduciary duties to, the Company, the Selling Shareholders or any other person, (ii) the Underwriter owes the Company and the Selling Shareholders 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 and the Selling Shareholders. Each of the Company and the Selling Shareholders waive to the full extent permitted by applicable law any claims that the Company or such Selling Shareholder may have against the Underwriter arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

16. 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.

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

18. 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.

19. 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 Barclays Capital Inc. at ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Syndicate Registration (Fax: (▇▇▇) ▇▇▇-▇▇▇▇), with a copy to the Director of Litigation, Office of the General Counsel, Barclays Capital Inc., ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇; if to the Company shall be delivered, mailed or sent to Rapid7, Inc., ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇; and if to any Selling Shareholder shall be delivered, mailed or sent to such Selling Shareholder at the address set forth on Schedule II hereto.

Barclays Capital Inc.

▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

The undersigned understands that Barclays Capital Inc. (the “Underwriter”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Rapid7, Inc., a Delaware corporation (the “Company”), and certain selling shareholders of the Company, providing for the public offering (the “Public Offering”) by the Underwriter of shares (the “Shares”) of the common stock, par value $0.01 per share of the Company (the “Common Stock”).

To induce the Underwriter to continue its efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Underwriter, the undersigned will not, during the period commencing on the date hereof and ending 60 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”) (such period, the “Restricted Period”), (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 Securities Exchange Act of 1934, as amended (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 the Public Offering or in open market transactions after the completion of the Public 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 the Public Offering or in such open market transactions;

(b) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock (i) as a bona fide gift, (ii) for bona fide estate planning purposes, (iii) upon death or by will, testamentary document or intestate succession, (iv) to an immediate family member of the undersigned or to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this agreement, “immediate family” shall mean any relationship by blood, current or former marriage or adoption, not more remote than first cousin), (v) not involving a change in beneficial ownership, or (vi) if the undersigned is a trust, to any beneficiary of the undersigned or the estate of any such beneficiary;

A-1

(c) distributions of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to stockholders, direct or indirect affiliates (within the meaning set forth in Rule 405 under the Securities Act of 1933, as amended), current or former partners (general or limited), members or managers of the undersigned, as applicable, or to the estates of any such stockholders, affiliates, partners, members or managers;

(d) (i) the exercise by the undersigned of options or warrants to purchase shares of Common Stock, insofar as such options or warrants are outstanding as of the date of the Prospectus, provided that the shares of Common Stock received upon exercise of such option or warrant shall remain subject to this lock-up agreement, or (ii) the transfer of shares of Common Stock or any securities convertible into Common Stock to the Company upon a vesting event of the Company’s securities or upon the exercise of options or warrants to purchase the Company’s securities on a “cashless” or “net exercise” basis to the extent permitted by the instruments representing such options or warrants so long as such “cashless” exercise or “net exercise” is effected solely by the surrender of outstanding options or warrants to the Company and the Company’s cancellation of all or a portion thereof to pay the exercise price and/or withholding tax obligations, but for the avoidance of doubt, excluding all methods of exercise that would involve a sale of any shares of Common Stock relating to options or warrants, whether to cover the applicable exercise price, withholding tax obligations or otherwise, provided that in the case of either (i) or (ii), no filing under Section 16(a) of the Exchange Act, or any other public filing or disclosure of such receipt or transfer by or on behalf of the undersigned, shall be required or shall be voluntarily made during the Restricted Period;

(e) the establishment of a trading plan (a “10b5-1 Plan”) pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Common Stock, provided that (i) such plan does not provide for the transfer of Common Stock during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the Restricted Period;

(f) the transfer of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock that occurs by operation of law pursuant to a qualified domestic order in connection with a divorce settlement or other court order;

(g) any transfer of Common Stock to the Company pursuant to arrangements in effect on the date hereof under which the Company has the option to repurchase such shares or a right of first refusal with respect to transfers of such shares upon termination of service of the undersigned, provided that no filing under Section 16(a) of the Exchange Act, or any other public filing or disclosure of such transfer by or on behalf of the undersigned, shall be required or shall be voluntarily made during the Restricted Period;

(h) sales of Common Stock to the Underwriter pursuant to the terms of the Underwriting Agreement;

A-2

(i) the agreement to transfer or the transfer of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the Board of Directors of the Company, made to all holders of Common Stock involving a Change of Control (as defined below) (including any support or voting agreement entered into in connection therewith), provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Common Stock owned by the undersigned shall remain subject to the restrictions contained in this agreement; and

(j) any transfer of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock pledged in a bona fide transaction to third parties as collateral to secure obligations pursuant to lending or other arrangements between such third parties (or their affiliates or designees) and the undersigned and/or its affiliates or any similar arrangement relating to a financing arrangement for the benefit of the undersigned and/or its affiliates; provided that in the case of pledges or similar arrangements under this clause (j), any such pledgee or other party shall, upon foreclosure on the pledged securities, sign and deliver a lock-up agreement substantially in the form of this agreement; provided further that no filing under Section 16(a) of the Exchange Act, or any other public filing or disclosure of such transfer by or on behalf of the undersigned, shall be required or shall be voluntarily made during the Restricted Period;

provided that in the case of any transfer or distribution pursuant to clause (b), (c) or (f), and in the case of foreclosure on the pledged shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock pursuant to clause (j), each transferee, donee, distributee or pledgee shall sign and deliver a lock-up agreement substantially in the form of this agreement;

provided further that in the case of any transfer or distribution pursuant to clause (b) or (c), (i) such transfer shall not involve a disposition of value and (ii) no filing under Section 16(a) of the Exchange Act, or any other public filing or disclosure of such transfer by or on behalf of the undersigned, 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 filing on Form 5 made after the expiration of the Restricted Period); and

provided further that in the case of any transfer pursuant to clause (f), any filings under Section 16(a) of the Exchange Act shall state that the transfer is by operation of law, court order, or in connection with a divorce settlement, as the case may be.

For the purposes of clause (i), “Change of Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons (other than the Underwriter pursuant to the Public Offering), of the Company’s voting securities if, after such transfer, such person or group of affiliated persons would hold more than 50% of the outstanding voting securities of the Company (or the surviving entity).

Notwithstanding the foregoing provisions of this agreement, the undersigned will be permitted to sell shares of Common Stock pursuant to a 10b5-1 Plan in effect as of the date hereof so long as any required filing under Section 16(a) of the Exchange Act specifies that the sale or transfer was made pursuant to such plan.

A-3

In addition, the undersigned agrees that, without the prior written consent of the Underwriter, it will not, during the Restricted Period, 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 (other than the exercise of any piggy-back rights permitted in connection with a Pro-Rata Release in connection with an Underwritten Sale, both as defined below). 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.

In the event that a release is granted to any director, officer or 1% or greater equity holder other than the undersigned relating to the foregoing restrictions for shares of Common Stock, the same percentage of shares of Common Stock held by the undersigned (the “Pro-Rata Release”) shall be immediately and fully released on the same terms from any such restrictions; provided, however, that such Pro-Rata Release shall not be applied in the event of (a) releases granted to any individual party by the Underwriter of shares with a value of $250,000 or less, or (b) any primary or secondary public offering or sale of shares of Common Stock that is underwritten (an “Underwritten Sale”) during the Restricted Period unless the undersigned participates in the Underwritten Sale, in which case the undersigned may participate on a pro rata basis with and otherwise on the same terms as any other equity holders in such Underwritten Sale. In the event that any percentage of such Common Stock released from the foregoing restrictions are subject to any restrictions of the type set forth in clause (1) or (2) of the second paragraph of this agreement, the same restrictions shall be applicable to the release of the same percentage of Common Stock held by the undersigned. In the event that the undersigned is released from any of its obligations under this agreement or, by virtue of this agreement, becomes entitled to offer, pledge, sell, contract to sell or otherwise dispose of any shares of Common Stock (or any securities convertible into Common Stock) prior to the termination of the Restricted Period, the Underwriter shall use its commercially reasonable efforts to provide notification of such to the undersigned within three business days thereof; provided that the failure to provide such notice shall not give rise to any claim or liability against the Underwriter.

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

This agreement and any claim, controversy or dispute arising under or related to this agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

Notwithstanding anything to the contrary contained herein, this agreement will automatically terminate and the undersigned will be released from all of his, her or its obligations hereunder upon the earliest to occur, if any, of (i) the date the Company, on the one hand, or the Underwriter, on the other hand, advises in writing that it has determined not to proceed with the Public Offering prior to the execution of the Underwriting Agreement, (ii) the Company files an application with the Securities and Exchange Commission to withdraw the registration statement

A-4

related to the Public Offering, (iii) the date the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares to be sold thereunder, or (iv) March 16, 2018, if the Underwriting Agreement has not been executed by such date.

[The remainder of this page is intentionally left blank.]

A-5

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. The Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company, the Selling Shareholders named therein and the Underwriter.
