Ladies and Gentlemen:

MongoDB, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several purchasers named in Schedule I hereto (the “Initial Purchasers”) $1,000,000,000 principal amount of its 0.25% Convertible Senior Notes due 2026 (the “Firm Securities”) to be issued pursuant to the provisions of an Indenture, to be dated as of January 14, 2020 (the “Indenture”) between the Company and U.S. Bank National Association, as Trustee (the “Trustee”). The Company also proposes to issue and sell to the Initial Purchasers not more than an additional $150,000,000 principal amount of its Convertible Senior Notes due 2026 (the “Additional Securities”), if and to the extent that you, as the Representatives, shall have determined to exercise, on behalf of the Initial Purchasers, the right to purchase such Additional Securities granted to the Initial Purchasers in Section 2 hereof. The Firm Securities and the Additional Securities are hereinafter collectively referred to as the “Securities.” The Securities will be convertible into cash, shares of the Company’s Class A common stock, par value $0.001 per share (the “Underlying Securities”) or a combination of cash and Underlying Securities, at the Company’s option. The Underlying Securities, together with the Company’s Class B common stock, par value $0.001 per share (the “Class B Stock”), is referred to herein as “Common Stock.”

The Securities and the Underlying Securities will be offered without being registered under the Securities Act of 1933, as amended (the “Securities Act”), to qualified institutional buyers in compliance with the exemption from registration provided by Rule 144A under the Securities Act.

In connection with the sale of the Securities, the Company has prepared a preliminary offering memorandum (the “Preliminary Memorandum”) and will prepare a final offering memorandum (the “Final Memorandum”) including or incorporating by reference a description of the terms of the Securities and the Underlying Securities, the terms of the offering and a description of the Company. For purposes of this Agreement, “Additional Written Offering Communication” means any written communication (as defined in Rule 405 under the Securities Act) that constitutes an offer to sell or a solicitation of an offer to buy the Securities other than the Preliminary Memorandum or the Final Memorandum; “Time of Sale Memorandum” means the Preliminary Memorandum together with each Additional Written Offering Communication or other information, if any, each identified in Schedule II hereto under the caption Time of Sale Memorandum; and “General Solicitation” means any offer to sell or solicitation of an offer to buy the Securities by any form of general solicitation or advertising (as those terms are used in Regulation D under the Securities Act). As used herein, the terms Preliminary Memorandum, Time of Sale Memorandum and Final Memorandum shall include the documents, if any, incorporated by reference therein on the date hereof. The terms “supplement”, “amendment” and “amend” as used herein with respect to the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum or any Additional Written Offering Communication shall include all documents subsequently filed by the Company with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are deemed to be incorporated by reference therein.

In connection with the offering of the Firm Securities, the Company is separately entering into capped call transactions with certain financial institutions, including with one or more of the Initial Purchasers (or affiliates thereof) (the “Capped Call Counterparties”), in each case pursuant to capped call confirmations (the “Base Capped Call Confirmations”) to be dated the date hereof, and in connection with any exercise by the Initial Purchasers of their option to purchase any Additional Securities, the Company and the Capped Call Counterparties may enter into additional capped call transactions pursuant to additional capped call confirmations (the “Additional Capped Call Confirmations”), each to be dated the date on which the Initial Purchasers exercise their option to purchase such Additional Securities.

2. Agreements to Sell and Purchase. The Company hereby agrees to sell to the several Initial Purchasers, and each Initial Purchaser, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Firm Securities set forth in Schedule I hereto opposite its name at a purchase price of 98.30% of the principal amount thereof (the “Purchase Price”).

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Initial Purchasers the Additional Securities, and the Initial Purchasers shall have the right to purchase, severally and not jointly, up to $150,000,000 principal amount of Additional Securities at the Purchase Price. The Representatives may exercise this right on behalf of the Initial Purchasers in whole or from time to time in part by giving written notice to the Company; provided that the Option Closing Date (as defined below) shall occur within a period of 13 calendar days from, and including, the Closing Date. Any exercise notice shall specify the principal amount of Additional Securities to be purchased by the Initial Purchasers and the date on which such Additional Securities are to be purchased.

(l) During the period of one year after the Closing Date or any Option Closing Date, if later, the Company will not, and will not permit any person that is a controlled affiliate (as defined in Rule 144 under the Securities Act) at such time (or has been a controlled affiliate within the three months preceding such time) to, resell any of the Securities or the Underlying Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them, unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Securities no longer being a “restricted security” under Rule 144.

(m) Not to take any action prohibited by Regulation M under the Exchange Act in connection with the distribution of the Securities contemplated hereby.

(n) The Company will deliver to each Initial Purchaser (or its agent), on the date of execution of this Agreement, a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation, and the Company undertakes to provide such additional supporting documentation as each Initial Purchaser may reasonably request in connection with the verification of the foregoing Certification.

The Company also agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC and ▇▇▇▇▇▇▇ Sachs & Co. LLC on behalf of the Initial Purchasers, it will not, during the period ending 60 days after the date of the Final Memorandum ( 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 or any securities 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 or (3) confidentially submit or file any registration statement with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock.

The foregoing sentence shall not apply to (a) the sale of the Securities under this Agreement and the issuance of Underlying Securities upon conversion thereof, (b) the issuance by the Company of any shares of Common Stock or securities convertible into or exercisable for Common Stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options, in each case outstanding on the date hereof of which the Initial Purchasers have been advised in writing, (c) grants of stock options, stock awards, restricted stock or other equity awards and the issuance of Common Stock or securities convertible into or exercisable for Common Stock (whether upon the exercise of stock options or otherwise) to employees, officers, directors, advisors, or consultants of the Company pursuant to the terms of a plan in effect on the date hereof and described in the Time of Sale Memorandum, (d) the entry into an agreement providing for the issuance by the Company of Common Stock or securities convertible into, exercisable for or which are otherwise exchangeable for or represent the right to receive Common Stock in connection with (x) the acquisition by the Company or any of its subsidiaries of the securities, business, technology, property or other assets of another person or entity or pursuant to an employee benefit plan assumed by the Company in connection with such acquisition, and the issuance of any Common Stock or securities convertible into, exercisable for or which are otherwise exchangeable for or represent the right to receive Common Stock pursuant to any such agreement or (y) the Company’s joint ventures, commercial relationships and other strategic transactions, provided that the aggregate number of shares of Common Stock, securities convertible into, exercisable for or which are otherwise exchangeable for or represent the right to receive Common Stock that the Company may sell or issue or agree to sell or issue pursuant to this clause (d) shall not exceed 5% of the total number of shares of Common Stock outstanding immediately following the completion of the transactions contemplated by this Agreement and all recipients of any such securities shall enter into a lock-up letter substantially in the form of Exhibit A covering the remainder of the Restricted Period, (e) the establishment or amendment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares 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 the Company regarding the establishment or amendment 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 or (f) the filing of any registration statement on Form S-8 relating to securities granted or to be granted pursuant to any plan in effect on the date hereof and described in the Time of Sale Memorandum or any assumed benefit plan contemplated by clause (d).

7. Offering of Securities; Restrictions on Transfer. (a) Each Initial Purchaser, severally and not jointly, represents and warrants that such Initial Purchaser is a qualified institutional buyer as defined in Rule 144A under the Securities Act (a “QIB”). Each Initial Purchaser, severally and not jointly, agrees with the Company that (i) it will not solicit offers for, or offer or sell, such Securities by any General Solicitation, other than a permitted communication listed on Schedule II hereto, or those made with the prior written consent of the Company, or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act, and (ii) it will sell such Securities in the United States only to persons that it reasonably believes to be QIBs, that in purchasing such Securities are deemed to have represented and agreed as provided in the Final Memorandum under the captions “Notice to Investors” and “Transfer Restrictions”.

(b) The Company agrees that the Initial Purchasers may provide copies of the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum and any other agreements or documents relating thereto, including without limitation, the Indenture, to Xtract Research LLC (“Xtract”), following completion of the offering, for inclusion in an online research service sponsored by Xtract, access to which shall be restricted by Xtract to QIBs.

8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Initial Purchaser, each person, if any, who controls any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Initial Purchaser within the meaning of Rule 405 under the Securities 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) that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Time of Sale Memorandum, any Additional Written Offering Communication prepared by or on behalf of, used by, or referred to by the Company, any General Solicitation made by the Company, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), the Final Memorandum or any amendment or supplement thereto, or that arise out of, or are based upon, any 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, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use therein.

(b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers 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 to the same extent as the foregoing indemnity from the Company to such Initial Purchaser, but only with reference to information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the 7^th, 8^th and 13^th paragraphs under the caption “Plan of Distribution” in the Preliminary Memorandum and the Time of Sale Memorandum, any Additional Written Offering Communication set forth in Schedule II hereto, road show, General Solicitation set forth in Schedule II hereto, the 7^th, 8^th and 13^th paragraphs under the caption “Plan of Distribution” in the Final Memorandum or any amendment or supplement thereto.

(c) 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 8(a) or 8(b), 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 reasonably incurred, documented 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 in writing to the retention of such counsel; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party; or (iv) 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 all Initial Purchasers and all persons, if any, who control any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act and (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 Preliminary Statement and each person, if any, who controls the Company 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 Initial Purchasers and such control persons and affiliates of any Initial Purchaser, such firm shall be designated in writing by the Representatives. 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 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 (i) includes an unconditional release of such indemnified party in form and substance reasonably satisfactory to 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..

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) 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 Securities or (ii) if the allocation provided by clause 8(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 8(d)(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 on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total discounts received by the Initial Purchasers bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and of the Initial Purchasers 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 or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

(e) The Company and the Initial Purchasers agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Initial Purchasers 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 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) 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 8, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities resold by it in the initial placement of such Securities were offered to investors exceeds the amount of any damages that such Initial Purchaser 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 8 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.

(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company 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 any Initial Purchaser, any person controlling any Initial Purchaser or any affiliate of any Initial Purchaser 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 Securities.

9. Termination. The Initial Purchasers may terminate this Agreement by notice given by the Representatives 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 NYSE MKT, 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 Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum or the Final Memorandum.

10. Effectiveness; Defaulting Initial Purchasers. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, or an Option Closing Date, as the case may be, any one or more of the Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, the other Initial Purchasers shall be obligated severally in the proportions that the principal amount of Firm Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Firm Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Initial Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Initial Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Firm Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Firm Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or of the Company. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Time of Sale Memorandum, the Final Memorandum or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Additional Securities and the aggregate principal amount of Additional Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Additional Securities to be purchased on such Option Closing Date, the non-defaulting Initial Purchasers shall have the option to (a) terminate their obligation hereunder to purchase the Additional Securities to be sold on such Option Closing Date or (b) purchase not less than the principal amount of Additional Securities that such non-defaulting Initial Purchasers would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

If this Agreement shall be terminated by the Initial Purchasers, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement required to be complied with, or if for any reason the Company shall be unable to perform its obligations under this Agreement other than by reason of a default by the Initial Purchasers or the occurrence of any of the events described in clauses (i), (iii), (iv) or (v) of Section 11, the Company will reimburse the Initial Purchasers or such Initial Purchasers as have so terminated this Agreement with respect to themselves, severally, for all documented out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Initial Purchasers in connection with this Agreement or the offering contemplated hereunder, and in the case of a default by the Initial Purchasers, the Company will reimburse the non-defaulting Initial Purchasers who have terminated this Agreement, severally, for all of their documented out-of-pocket expenses (including their pro rata share of fees and disbursements of their counsel) reasonably incurred by such non-defaulting Initial Purchasers in connection with this Agreement. Notwithstanding the foregoing sentence, if, after the Closing Date but prior to any Option Closing Date with respect to the purchase of any Additional Securities pursuant to a notice delivered by the Representatives to the Company under Section 2 hereof, the Company fails or refuses to comply with the terms or to fulfill any of the conditions of the Agreement in connection with such Option Closing Date, the Company will reimburse the Initial Purchasers severally for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Initial Purchasers in connection with the proposed purchase of any such Additional Securities pursuant to this Agreement.

11. 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 Securities, represents the entire agreement between the Company and the Initial Purchasers with respect to the preparation of the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum, the conduct of the offering, and the purchase and sale of the Securities.

(b) The Company acknowledges that in connection with the offering of the Securities: (i) the Initial Purchasers have acted at arms’ length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Initial Purchasers owe 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 Initial Purchasers 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 Initial Purchasers arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

12. Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Initial Purchaser that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Initial Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Initial Purchaser that is a Covered Entity or a BHC Act Affiliate of such Initial Purchaser becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Initial Purchaser are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

13. 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.

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

15. 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.

Ladies and Gentlemen:

The undersigned understands that ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇”), ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Co. LLC (“Goldman”), Barclays Capital Inc. (“Barclays”) and Citigroup Global Markets Inc. (“Citi”) propose to enter into a Purchase Agreement (the “Purchase Agreement”) with MongoDB, Inc., a Delaware corporation (the “Company”), providing for the offering (the “Offering”) by the several Initial Purchasers (the “Initial Purchasers”), including ▇▇▇▇▇▇ Stanley, Goldman, Barclays and Citi of $1,000,000,000 principal amount of Convertible Senior Notes due 2026 of the Company (the “Securities”). The Securities will be convertible into cash, shares of Class A common stock, par value $0.001 per share, of the Company (the “Class A Stock”) or a combination of cash and shares of Class A Stock, at the Company’s election.

A-1

To induce the Initial Purchasers that may participate in the Offering to continue their efforts in connection with the Offering, the undersigned hereby agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and Goldman (collectively, the “Representatives”) on behalf of the Initial Purchasers, it will not, and will not publicly announce its intention to, during the period commencing on the date hereof and ending 60 days after the date of the final offering memorandum (the “Restricted Period”) relating to the Offering (the “Final Memorandum”), (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 open market transactions after the completion of the Offering, provided that 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 in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions during the Restricted Period;

(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) to an immediate family member (as defined below) or to any trust for the direct or indirect benefit of the undersigned or an immediate family member of the undersigned, (iii) to any corporation, partnership, limited liability company, investment fund or other entity controlled or managed, or under common control or management by, the undersigned, or (iv) by will, other testamentary document or intestate succession to the legal representative, heir, beneficiary or an immediate family member of the undersigned, provided that, in the case of any transfer pursuant to this clause (b), (i) each transferee shall sign and deliver a lock-up agreement substantially in the form of this agreement, (ii) 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 and (iii) such transfer shall not involve a disposition for value;

(c) transfers or distributions of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to current or former general or limited partners, managers or members, stockholders or direct or indirect affiliates (within the meaning of Rule 405 under the Securities Act of 1933, as amended) of the undersigned or to the estates of any of the foregoing; provided that in the case of any transfer or distribution pursuant to this clause (c), (i) each transferee or distributee shall sign and deliver a lock-up agreement substantially in the form of this agreement, (ii) 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 and (iii) such transfer shall not involve a disposition for value;

(e) (i) the transfer of shares of Common Stock pursuant to a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock (each, a “10b5-1 Plan”) in effect as of the date hereof, provided that any filing required under Section 16(a) of the Exchange Act during the Restricted Period shall clearly indicate in the footnotes thereto that the filing relates to a transaction pursuant to a 10b5-1 Plan and (ii) the establishment of a10b5-1 Plan for the transfer of shares of Common Stock, provided that (A) such 10b5-1 Plan does not provide for the transfer of Common Stock during the Restricted Period and (B) 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 during the Restricted Period, 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;

A-3

(f) the transfer of shares 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 or in connection with a divorce settlement or other court order, provided that (i) the transferee shall sign and deliver a lock-up agreement substantially in the form of this agreement, (ii) any filing required under Section 16(a) of the Exchange Act during the Restricted Period shall clearly indicate in the footnotes thereto that the filing relates to the circumstances described above and (iii) the undersigned does not otherwise voluntarily effect any other public filing or announcement regarding such transfers during the Restricted Period; or

(g) 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), 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; or

(h) the conversion of shares of Class B Stock into shares of Class A Stock, provided that, in each case, such shares shall continue to be subject to the restrictions on transfer set forth in this agreement.

As used herein, (i) “immediate family member” means the spouse, domestic partner, lineal descendant, father, mother, brother, sister, or any other person with whom the undersigned has a relationship by blood, marriage or adoption not more remote than first cousin and (ii) “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 an Initial Purchaser pursuant to the Offering), of the Company’s voting securities if, after such transfer, such person or group of affiliated persons would hold more than 65% of the number of outstanding voting securities of the Company (or the surviving entity) and 65% of the voting control of the outstanding voting securities of the Company (or the surviving entity).

In addition, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Initial Purchasers, 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. 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.

A-4

The undersigned understands that the Company and the Initial Purchasers 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 a Purchase Agreement, the terms of which are subject to negotiation between the Company and the Initial Purchasers.

This agreement shall automatically terminate and the undersigned will be released from all obligations hereunder upon the earliest to occur, if any, of (a) the Company, on the one hand, or the Representatives, on the other hand, advising the other in writing that it has determined not to proceed with the Offering prior to the execution of the Purchase Agreement, (b) the date the Purchase Agreement is terminated, if prior to the closing of the Offering, and (c) January 27, 2020, if the Purchase Agreement has not been executed by such date.

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 laws of the State of New York, without regard to the conflict of laws principles thereof.
