 Exhibit 10.16 
 EXECUTIVE EMPLOYMENT AGREEMENT 
 This EXECUTIVE
EMPLOYMENT AGREEMENT (the “Agreement”) is entered into effective [—] (the “Effective Date”), by and
between [—] (“Executive”) and GLYCOMIMETICS, INC. (the “Company”). 
 WHEREAS, Executive has been employed by the Company pursuant to an Employment Agreement dated [—] (“Prior Agreement”);

 WHEREAS, the Company and Executive wish to supersede the Prior Agreement with this Agreement; and 

WHEREAS, the Company desires to continue to employ Executive to provide personal services to the Company, and Executive wishes to
continue to be employed by the Company and provide personal services to the Company in return for certain compensation and benefits. 
 Accordingly, in consideration of the mutual promises and covenants contained herein, the parties agree to the following: 
 1. EMPLOYMENT BY THE COMPANY. 
 1.1 Term. The term of employment hereunder will be for the four year period commencing on the Effective Date and ending on the fourth anniversary of the Effective Date, subject to
termination prior thereto pursuant to Sections 5, 6, 7, 8 or 9 below. Unless the Company gives notice of its intent not to renew Executive’s employment hereunder, or Executive gives written notice to the
Company of his determination not to renew his service and employment hereunder, in any case at least one year prior to the fourth anniversary of the Effective Date, this Agreement, and Executive’s employment by the Company hereunder, shall be
renewed for one year from that anniversary. Thereafter, unless the Company or Executive gives written notice of determination not to renew at least one year prior to the next succeeding anniversary of the Effective Date, this Agreement shall be
renewed for one year from that anniversary. The term “Service Period” shall mean the four year period provided for in this Section 1.2 and any extension thereof, or any shorter period resulting from any termination of
service under Sections 5, 6, 7, 8 or 9 hereof. 
 1.2 Position. Executive will
be assigned initially to the position of [—] of the Company. During the term of Executive’s employment with the Company, Executive will devote his best efforts and substantially all of his
business time and attention to the business of the Company. 
 1.3 Duties. Executive will report to the Chairman
of the Board of the Company and/or such other Board officers, company executives and/or committees designated by the Chairman, performing such duties as are normally associated with his then current position and such duties as are assigned to him
from time to time, subject to the oversight and direction of the Chairman of the Board or her/his designee. Executive shall perform his duties under this Agreement principally out of the Company’s Gaithersburg, Maryland location, or such other
location as assigned. In addition, Executive shall make such business trips to such places as may be necessary or advisable for the efficient operations of the Company. 

 1.4 Company Policies and Benefits. The employment relationship between the
parties shall also be subject to the Company’s personnel policies and procedures as they may be interpreted, adopted, revised or deleted from time to time in the Company’s sole discretion. Executive will be eligible to participate on the
same basis as similarly situated employees in the Company’s benefit plans in effect from time to time during his employment. All matters of eligibility for coverage or benefits under any benefit plan shall be determined in accordance with the
provisions of such plan. The Company reserves the right to change, alter, or terminate any benefit plan in its sole discretion. Notwithstanding the foregoing, in the event that the terms of this Agreement differ from or are in conflict with the
Company’s general employment policies or practices, this Agreement shall control. 
 1.5 Time to be Devoted to
Service. Except for reasonable vacations, absences due to temporary illness, and activities that may be mutually agreed to by the parties, Executive shall devote his entire time, attention and energies during normal business hours and such
evenings and weekends as may be reasonably required for the discharge of his duties to the business of the Company during the Service Period. During the Service Period, Executive will not be engaged in any other business activity, which, in the
reasonable judgment of the Chairman of the Board of the Company, conflicts with the duties of Executive hereunder, whether or not such activity is pursued for gain, profit or other pecuniary advantage. The Company further acknowledges and agrees
that, subject to the prior written approval by a majority of the Board of Directors (which majority shall exclude Executive if Executive is a then current member of the Board of Directors) and consistent with the terms of the Compliance Agreement
(as defined below), Executive may serve on the boards of directors and advisory boards of other companies provided that such service does not interfere with the performance of Executive’s duties hereunder. 

2. COMPENSATION. 
 2.1 Base Salary. Executive shall receive for Executive’s services to be rendered hereunder an initial annualized base salary of $[—],
subject to review and adjustment from time to time by the Company in its sole discretion and payable subject to standard federal and state payroll withholding requirements in accordance with Company’s standard payroll practices
(“Base Salary”). 
 2.2 Bonus. Subject to the Board’s approval, Executive shall be
eligible for such bonuses as are awarded from time to time by the Board in its sole discretion based on Executive’s continuous performance of services to the Company through the date that any bonus is paid and upon achievement of objectives set
by the Company. Neither the fact nor the amount of any bonus is guaranteed. 
 2.3 Expense Reimbursement. The
Company will reimburse Executive for reasonable business expenses in accordance with the Company’s standard expense reimbursement policy.

 3. PROPRIETARY INFORMATION, INVENTIONS,
NON-COMPETITION AND NON-SOLICITATION OBLIGATIONS. The parties hereto have entered into a Compliance Agreement attached
hereto as Exhibit A (the “Compliance Agreement”), which may be amended by the parties from time to time without regard to this Agreement. The Compliance Agreement contains provisions that are intended by the parties to
survive and do survive termination or expiration of this Agreement. 
 4. NO CONFLICT
WITH EXISTING OBLIGATIONS. Executive represents that Executive’s performance of all the terms of this Agreement and as an Executive of the Company do not and
will not breach any agreement or obligation of any kind made prior to Executive’s employment by the Company, including agreements or obligations Executive may have with other employers or entities for which Executive has provided services.
Executive has not entered into, and Executive agrees that Executive will not enter into, any agreement or obligation, either written or oral, in conflict herewith. 
 5. TERMINATION DUE TO DEATH OR DISABILITY. 

5.1 Death or Disability. If Executive dies while employed pursuant to this Agreement, then all obligations of the parties
hereunder shall terminate immediately. If Executive is incapacitated or disabled by accident, sickness or otherwise so as to render him mentally or physically incapable of performing the essential functions of his position with or without a
reasonable accommodation for a period of 90 consecutive days or longer, or for 90 days in the aggregate during any six-month period (such condition being herein referred to as “Disability”), the Company, at its option, may terminate
Executive’s employment under this Agreement immediately upon giving him notice to that effect. This definition shall be interpreted and applied consistent with the Americans with Disabilities Act, the Family and Medical Leave Act, and other
applicable law. Termination pursuant to this Section 5 is hereinafter referred to as an “Death or Disability Termination”. 
 5.2 Substitution. The Board of Directors may designate another employee to act in Executive’s place during any period of Executive’s Disability during the Service Period.
Notwithstanding any such designation, Executive shall continue to receive Executive’s Base Salary and benefits in accordance with Sections 1.4 and 2 of this Agreement until Executive becomes eligible for disability income under the
Company’s disability income insurance (if any) or until the termination of Executive’s employment, whichever shall first occur. 
 5.3 Disability Income Payments. While receiving disability income payments under the Company’s disability income insurance (if any), Executive shall not be entitled to receive any Base
Salary, but shall continue to be eligible to participate in all other compensation and benefits in accordance with Sections 1.4 and 2 until the date of his termination. 
 5.4 Verification of Disability. If any question shall arise as to whether during any period Executive is disabled through any illness, injury, accident or condition of either a physical or
psychological nature so as to be unable to perform substantially all of Executive’s duties and responsibilities hereunder, Executive may, and at the request of the Company shall, submit to a medical examination by a physician selected by the
Company to 

  
 3 

 
whom Executive or Executive’s guardian has no reasonable objection to determine whether Executive is so disabled and such determination shall for the purposes of this Agreement be conclusive
of the issue. If such question shall arise and Executive shall fail to submit to such medical examination, the Company’s determination of the issue shall be binding on Executive. 

6. TERMINATION FOR CAUSE. The Company, on
recommendation from the Board of Directors of the Company, may terminate the employment of Executive hereunder at any time for “cause” (such termination being hereinafter referred to as a “Termination for Cause”) by giving
Executive notice of such termination as described in Section 9.5, upon the giving of such notice termination shall take effect immediately. For the purpose of this Section 6, “cause” will mean that the
Company has determined in its sole discretion that any of the following occurred: (a) Executive’s breach of fiduciary duty or substantial misconduct with respect to the business and affairs of the Company or any subsidiary or affiliate
thereof, (b) Executive’s neglect of duties or failure to act which can reasonably be expected to materially adversely affect the business or affairs of the Company, the Company or any subsidiary or affiliate thereof,
(c) Executive’s material breach of this Agreement, or of any provision of the Compliance Agreement which, to the extent curable, is not cured within 15 days after written notice thereof is given to Executive, (d) the commission by
Executive of an act involving moral turpitude or fraud, (e) Executive’s conviction of any felony, or of any misdemeanor involving fraud, theft, embezzlement, forgery or moral turpitude, (f) other conduct by Executive that is
materially harmful to the business or reputation of the Company, or (g) the expiration of this Agreement. 
 7.
TERMINATION WITHOUT CAUSE. The Company, on recommendation from the Board of Directors of the Company, may terminate the employment of Executive hereunder at any
time without “cause” (such termination being hereinafter called a “Termination Without Cause”) by giving Executive notice of such termination as described in Section 9.5. Executive’s termination of
employment under this Section 7 will take effect immediately upon the giving of such notice. 
 8.
RESIGNATION BY EXECUTIVE. 
 8.1 Without Good
Reason. Any resignation by Executive other than for Good Reason (as defined below) will be referred to hereinafter as a “Voluntary Termination”. A Voluntary Termination will be deemed to be effective following notice under
Section 9.5. 
 8.2 With Good Reason. Provided Executive has not previously been notified of the
Company’s intention to terminate Executive’s employment, Executive may resign from employment with the Company for Good Reason (as defined below) by giving the Company written notice of such termination in compliance with
Section 9.5 and provided that such notice specifies: (i) the basis for termination; and (ii) the effective date of termination (such termination being hereinafter referred to as a “Termination for Good
Reason”). For purposes of this Agreement, the term “Good Reason” shall mean any of the following without Executive’s prior written consent: (x) any material diminution of Executive’s duties or
responsibilities hereunder (except in each case in connection with a Termination for Cause or as a result of Executive’s death or Disability), or, the assignment to Executive of duties or responsibilities that are materially inconsistent with
Executive’s then position; provided, however, that the acquisition of the Company and subsequent conversion of the Company to a 

  
 4 

 
division or unit of the acquiring company will not by itself result in a diminution of Executive’s duties or responsibilities; (y) any material breach of the Agreement by the Company
which is not cured within 15 business days after written notice thereof is given to the Company; or (z) a relocation of Executive from the Company’s principal office to a location more than 35 miles from the location of the Company’s
principal office, other than on required travel by Executive on the Company’s business or on a temporary basis not to exceed a period equal to two calendar months. 
 9. EFFECT OF TERMINATION OF EMPLOYMENT. 

9.1 Voluntary Termination, Death or Disability Termination, or a Termination for Cause. Upon the termination of
Executive’s employment hereunder pursuant to a Voluntary Termination, Death or Disability Termination, or a Termination for Cause, neither Executive nor his beneficiary or estate will receive severance payments, or any other severance
compensation or benefit, or have any further rights or claims against the Company, its affiliates, or its subsidiaries under this Agreement except to receive: 
 (a) the accrued but unpaid portion of Executive’s then current Base Salary, computed on a pro-rata basis to the date of such termination, subject to the Company’s standard payroll
policies; 
 (b) all compensation and benefits payable to Executive based on his then current participation in any
compensation or benefit plan, program or arrangement through the date of termination; and 
 (c) reimbursement for any
expenses for which Executive shall not have theretofore been reimbursed as provided in the Company’s standard expense reimbursement policy. 
 9.2 Termination Without Cause or for Good Reason (Other Than Change in Control). Upon the termination of Executive’s employment hereunder pursuant to a Termination Without Cause or a
Termination for Good Reason (other than in connection with a Change in Control (as defined below)), neither Executive nor his beneficiary or estate will have any further rights or claims against the Company, its affiliates or its subsidiaries under
this Agreement except to receive: 
 (a) a termination payment equal to that provided for in Section 9.1
hereto; and 
 (b) if Executive executes a general release in favor of the Company, in a form attached as Exhibit B (the
“Release”), and subject to Section 9.2(c) (the date that the Release becomes effective and may no longer be revoked by Executive is referred to as the “Release Date”), then the Company
shall pay to Executive the following severance benefits (such benefits referred to as “Severance Benefits”): (i) continuation of Executive’s then current Base Salary for a period of [—] months from the Release Date (such applicable period is referred to as the “Severance Period”), less applicable withholdings and deductions, on the Company’s regular
payroll dates; and (ii) payment of the premiums of Executive’s group health insurance COBRA continuation coverage, including coverage for Executive’s eligible dependents, for a 

  
 5 

 
maximum period of [—] months following his Termination Without Cause or a Termination for Good Reason (other than in connection with a Change
in Control (as defined below)) (such period subject to the qualifications of this Section 9.2(b) referred to as “COBRA Payment Period”); provided, however, that (a) the Company shall pay premiums for
Executive’s eligible dependents only for coverage for which those eligible dependents were enrolled immediately prior to the Termination Without Cause or Termination for Good Reason; and (b) the Company’s obligation to pay such
premiums shall cease immediately upon Executive’s eligibility for comparable group health insurance provided by a new employer of Executive. Vesting of any unvested stock options and/or other equity securities shall cease on the date of
termination following Executive’s Termination Without Cause or a Termination for Good Reason (other than in connection with a Change in Control (as defined below)). In addition, the Company’s severance obligation shall be reduced by the
amount of any salary received by Executive from another employer during the Severance Period. Executive agrees to inform the Company promptly if he obtains other employment during the Severance Period. Notwithstanding the foregoing, if at any time
the Company determines, in its sole discretion, that the payment of the COBRA premiums would result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Internal Revenue Code of 1988, as amended (the “Code”) or
any statute or regulation of similar effect (including, without limitation, the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education Reconciliation Act), then in lieu of providing the COBRA premiums, the
Company will instead pay Executive, on the first day of each month of the remainder of the COBRA Payment Period, a fully taxable cash payment equal to the COBRA premiums for that month, subject to applicable tax withholdings and deductions (such
amount, the “Special Severance Payment”). 
 (c) To receive the Severance Benefits pursuant to
Section 9.2(b), Executive’s termination or resignation must constitute a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h)) and Executive must execute and allow the Release to become
effective within 60 days of Executive’s termination or resignation. Executive’s ability to receive the Severance Benefits pursuant to Section 9.2(b) is further conditioned upon his: returning all Company property; complying
with his post-termination obligations under this Agreement and the Compliance Agreement, and complying with the Release including without limitation any non-disparagement and confidentiality provisions contained therein. The Severance Benefits
provided to Executive pursuant to Section 9.2(b) are in lieu of, and not in addition to, any benefits to which Executive may otherwise be entitled under any Company severance plan, policy or program. 

(d) The damages (if any) caused to Executive by a Termination Without Cause or a Termination for Good Reason would be difficult
to ascertain; therefore, the Severance Benefits for which Executive is eligible pursuant to Section 9.2(b) above in exchange for the Release is agreed to by the parties as liquidated damages, to serve as full compensation, and not a
penalty 
 9.3 Change in Control Severance Benefits.  

(a) In the event that the Company (or any surviving or acquiring corporation) terminates Executive’s employment for a
Termination Without Cause or Executive resigns in connection with a Termination for Good Reason within twelve (12) months following 

  
 6 

 
the effective date of a Change in Control (“Change in Control Termination”), and upon compliance with Section 9.2(c) above, Executive shall be eligible
to receive the following Change in Control severance benefits: (i) a lump-sum cash payment in an amount equal to Executive’s annual Base Salary then in effect for a period of [—] months,
less applicable withholdings and deductions, paid within 60 days following the Change in Control Termination; (ii) payment of Executive’s target bonus award for the year in which Executive’s employment terminates, prorated through the
date of the Change in Control Termination, paid within 60 days following the Change in Control Termination; and (iii) the Company (or any surviving or acquiring corporation) shall pay the premiums of Executive’s group health insurance
COBRA continuation coverage, including coverage for Executive’s eligible dependents, during the [—] month period following a Change in Control Termination (such period subject to the
qualifications of this Section 9.3(a) referred to as “CIC COBRA Payment Period”); provided, however, that (a) the Company (or any surviving or acquiring corporation) shall pay premiums for Executive’s
eligible dependents only for coverage for which those eligible dependents were enrolled immediately prior to the Change in Control Termination; and (b) the Company’s (or any surviving or acquiring corporation’s) obligation to pay such
premiums shall cease immediately upon Executive’s eligibility for comparable group health insurance provided by a new employer of Executive. Executive agrees that the Company’s (or any surviving or acquiring corporation’s) payment of
health insurance premiums will satisfy its obligations under COBRA for the period provided. No insurance premium payments will be made following the effective date of Executive’s coverage by a health insurance plan of a subsequent employer. For
the balance of the period that Executive is entitled to coverage under federal COBRA law, if any, Executive shall be entitled to maintain such coverage at Executive’s own expense. Notwithstanding the foregoing, if at any time the Company
determines, in its sole discretion, that the payment of the COBRA premiums would result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Code or any statute or regulation of similar effect (including, without
limitation, the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education Reconciliation Act), then in lieu of providing the COBRA premiums, the Company will instead pay Executive, on the first day of each
month of the remainder of the CIC COBRA Payment Period, the Special Severance Payment. 
 (b) To receive the payments in
Section 9.3(a), Executive’s termination or resignation must constitute a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h)) and Executive must execute and allow the Release to become
effective within 60 days of Executive’s termination or resignation. Executive’s ability to receive benefits pursuant to Section 9.3(a) is further conditioned upon his: returning all Company property; complying with his
post-termination obligations under this Agreement and the Compliance Agreement, and complying with the Release including without limitation any non-disparagement and confidentiality provisions contained therein. 

(c) In addition, notwithstanding anything contained in Executive’s stock option or other equity award agreements to the
contrary, upon a Change in Control Termination, Executive shall receive accelerated vesting of all then unvested shares of the Company’s Common Stock that he then may have, if any. 

(d) As used in this Agreement, a “Change in Control” is defined as the first to occur of the following:
(a) a sale, lease, exchange or other transfer in one transaction 

  
 7 

 
or a series of related transactions of all or substantially all of the assets of the Company (other than the transfer of the Company’s assets to a majority-owned subsidiary corporation);
(b) a merger or consolidation in which the Company is not the surviving corporation (unless the holders of the Company’s outstanding voting stock immediately prior to such transaction own, immediately after such transaction, securities
representing at least fifty percent (50%) of the voting power of the corporation or other entity surviving such transaction); (c) a reverse merger in which the Company is the surviving corporation but the shares of the Company’s
common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise (unless the holders of the Company’s outstanding voting stock immediately
prior to such transaction own, immediately after such transaction, securities representing at least fifty percent (50%) of the voting power of the Company); or (d) any transaction or series of related transactions in which in excess of 50%
of the Company’s voting power is transferred. Notwithstanding the foregoing, to the extent that the Company determines that any of the payments or benefits under this Agreement that are payable in connection with a Change in Control constitute
deferred compensation under Section 409A that may only be paid on a qualifying transaction (that is, they are not “exempt” under 409A), the foregoing definition of Change in Control shall apply only to the extent the transaction also
meets the definition used for purposes of Treasury Regulation Section 1.409A-3(a)(5), that is, as defined under Treasury Regulation Section 1.409A-3(i)(5). 
 9.4 Parachute Taxes 
 (a) If any payment or benefit Executive would
receive from the Company or otherwise in connection with a Change of Control or other similar transaction (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and
(ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment will be equal to the Reduced Amount. The “Reduced Amount” will be either (x) the
largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax, or (y) the largest portion, up to and including the total, of the Payment, whichever amount ((x) or (y)), after taking into account
all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Executive’s receipt of the greater economic benefit notwithstanding that all or some
portion of the Payment may be subject to the Excise Tax. If a Reduced Amount will give rise to the greater after tax benefit, the reduction in the Payments will occur in the following order: (a) reduction of cash payments; (b) cancellation
of accelerated vesting of equity awards other than stock options; (c) cancellation of accelerated vesting of stock options; and (d) reduction of other benefits paid to Executive. Within any such category of payments and benefits (that is,
(a), (b), (c) or (d)), a reduction will occur first with respect to amounts that are not “deferred compensation” within the meaning of Section 409A and then with respect to amounts that are. In the event that acceleration of
compensation from Executive’s equity awards is to be reduced, such acceleration of vesting will be canceled, subject to the immediately preceding sentence, in the reverse order of the date of grant. 

(b) The registered public accounting firm engaged by the Company for general audit purposes as of the day prior to the effective
date of the event described in Section 280G(b)(2)(A)(i) of the Code will perform the foregoing calculations. If the registered public accounting firm so engaged by the Company is serving as accountant or auditor for the acquirer

  
 8 

 
or is otherwise unable or unwilling to perform the calculations, the Company will appoint a nationally recognized firm that has expertise in these calculations to make the determinations required
hereunder. The Company will bear all expenses with respect to the determinations by such independent registered public accounting firm required to be made hereunder. The firm engaged to make the determinations hereunder will provide its
calculations, together with detailed supporting documentation, to the Company and Executive within thirty (30) calendar days after the date on which Executive’s right to a Payment is triggered (if requested at that time by the Company or
Executive) or such other time as reasonably requested by the Company or Executive. Any good faith determinations of the independent registered public accounting firm made hereunder will be final, binding and conclusive upon the Company and
Executive. 
 9.5 Notice; Effective Date of Termination.  

(a) Termination of Executive’s employment pursuant to this Agreement shall be effective on the earliest of: 

(i) immediately after the Company gives notice to Executive of Executive’s Termination for Cause or Termination Without
Cause unless the Company specifies a later date, in which case, termination shall be effective as of such later date; 

(ii) immediately upon Executive’s death; 
 (iii) immediately after the Company gives notice to Executive of Executive’s termination on account of Executive’s Disability, unless the Company specifies a later date, in which case,
termination shall be effective as of such later date, provided that Executive has not returned to the full time performance of Executive’s duties prior to such date; or 

(iv) ten (10) days after Executive gives written notice to the Company of Executive’s resignation for a Voluntary
Termination or Resignation for Good Reason; provided that the Company may set a termination date at any time between the date of notice and the date of resignation, in which case Executive’s resignation shall be effective as of such
other date. Executive will receive compensation through any required notice period. 
 (b) In the event notice of a
termination under subsections (a)(i), (iii) and (iv) is given orally, at the other party’s request, the party giving notice must provide written confirmation of such notice within five (5) business days of the request in
compliance with the requirement of Section 10.1 below. 
 9.6 Cooperation With Company After Termination of
Employment. Following termination of Executive’s employment for any reason, Executive shall fully cooperate with the Company in all matters relating to the winding up of Executive’s pending work including, but not limited to, any
litigation in which the Company is involved, and the orderly transfer of any such pending work to such other employees as may be designated by the Company. 
 9.7 Application of Section 409A. It is intended that all of the benefits and payments under this Agreement satisfy, to the greatest extent possible, the exemptions from the

  
 9 

 
application of Code Section 409A provided under Treasury Regulations 1.409A-1(b)(4) and 1.409A-1(b)(9), and
this Agreement will be construed to the greatest extent possible as consistent with those provisions. If not so exempt, this Agreement (and any definitions hereunder) will be construed in a manner that complies with Section 409A, and
incorporates by reference all required definitions and payment terms. For purposes of Code Section 409A (including, without limitation, for purposes of Treasury Regulation
Section 1.409A-2(b)(2)(iii)), Executive’s right to receive any installment payments under this Agreement (whether severance payments, reimbursements or otherwise) will be treated as a right to
receive a series of separate payments and, accordingly, each installment payment hereunder will at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this Agreement, if Executive is deemed by
the Company at the time of his Separation from Service to be a “specified employee” for purposes of Code Section 409A(a)(2)(B)(i), and if any of the payments upon Separation from Service set forth herein and/or under any other
agreement with the Company are deemed to be “deferred compensation”, then if delayed commencement of any portion of such payments is required to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i) and the related
adverse taxation under Section 409A, the timing of the payments upon a Separation from Service will be delayed as follows: on the earlier to occur of (i) the date that is six months and one day after the effective date of Executive’s
Separation from Service, and (ii) the date of Executive’s death (such earlier date, the “Delayed Initial Payment Date”), the Company will (A) pay to Executive a lump sum amount equal to the sum of the payments upon
Separation from Service that Executive would otherwise have received through the Delayed Initial Payment Date if the commencement of the payments had not been delayed pursuant to this paragraph, and (B) commence paying the balance of the
payments in accordance with the applicable payment schedules set forth above. No interest will be due on any amounts so deferred. To the extent that any severance payments or benefits payable to Executive pursuant to this Agreement are not otherwise
exempt from the application of Code Section 409A, then, if the period during which Executive may consider and sign the Release spans two calendar years, the payment of severance will not be made or begin until the later calendar year.

 10. GENERAL PROVISIONS. 

10.1 Notices. Any notices required hereunder to be in writing shall be deemed effectively given: (a) upon personal
delivery to the party to be notified, (b) when sent by electronic mail or confirmed facsimile if sent during normal business hours of the recipient, and if not, then on the next business day, (c) five (5) days after having been sent
by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All
communications shall be sent to the Company, “Attention Chief Executive Officer,” at its primary office location and to Executive at Executive’s address as listed on the Company payroll, or at such other address as the Company or
Executive may designate by ten (10) days advance written notice to the other. 
 10.2 Severability. Whenever
possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any
applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such
invalid, illegal or unenforceable provisions had never been contained herein. 

  
 10 

 10.3 Waiver. If either party should waive any breach of any provisions of this
Agreement, Executive or the Company shall not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement. 
 10.4 Complete Agreement. This Agreement constitutes the entire agreement between Executive and the Company with regard to the subject matter hereof. This Agreement is the complete, final,
and exclusive embodiment of their agreement with regard to this subject matter and supersedes any prior oral discussions or written communications and agreements, including the Prior Agreement. This Agreement is entered into without reliance on any
promise or representation other than those expressly contained herein, and it cannot be modified or amended except in writing signed by Executive and an authorized officer of the Company. The parties have entered into a separate Compliance Agreement
and have or may enter into separate agreement related to stock awards. These separate agreements govern other aspects of the relationship between the parties, have or may have provisions that survive termination of Executive’s employment under
this Agreement, may be amended or superseded by the parties without regard to this Agreement and are enforceable according to their terms without regard to the enforcement provision of this Agreement. 

10.5 Further Assurances. Executive agrees to execute, acknowledge, seal and deliver such further assurances, documents,
applications, agreements and instruments, and to take such further actions, as the Company may reasonably request in order to accomplish the purposes of this Agreement. 
 10.6 Counterparts. This Agreement may be executed in separate counterparts, any one of which need not contain signatures of more than one party, but all of which taken together will
constitute one and the same Agreement. 
 10.7 Headings. The headings of the sections hereof are inserted for
convenience only and shall not be deemed to constitute a part hereof nor to affect the meaning thereof. 
 10.8 Successors
and Assigns. This Agreement is intended to bind and inure to the benefit of and be enforceable by Executive and the Company, and their respective successors, assigns, heirs, executors and administrators, except that Executive may not assign
any of his duties hereunder and he may not assign any of his rights hereunder without the written consent of the Company, which shall not be withheld unreasonably. 
 10.9 Choice of Law. All questions concerning the construction, validity and interpretation of this Agreement will be governed by the law of the State of Maryland, without giving effect to
choice of law principles. Executive and the Company hereby expressly consent to the personal jurisdiction and venue of the state and federal courts located in the State of Maryland for any claims or suits arising from or related to this Agreement.

 IN WITNESS WHEREOF, the
parties have executed this Executive Employment Agreement on the day and year first written above.

any liabilities arising from your actions within the course and scope of your employment with the Company or within the course and scope of your role as a member of the Board of Directors and/or officer of the Company. Also excluded from this
Agreement are any claims which cannot be waived by law. You are waiving, however, your right to any monetary recovery should any governmental agency or entity, such as the EEOC or the DOL, pursue any claims on your behalf. You acknowledge that you
are knowingly and voluntarily waiving and releasing any rights you may have under the ADEA, as amended. You also acknowledge that (i) the consideration given to you in exchange for the waiver and release in this Agreement is in addition to
anything of value to which you were already entitled, and (ii) that you have been paid for all time worked, have received all the leave, leaves of absence and leave benefits and protections for which you are eligible, and have not suffered any on-the-job injury for which you have not already filed a claim. You further acknowledge that you have been advised by this writing that: (a) your waiver and release do not apply to any rights or claims that may
arise after the execution date of this Agreement; (b) you have been advised hereby that you have the right to consult with an attorney prior to executing this Agreement; (c) you have twenty-one (21) days to consider this Agreement

agree to return to the Company all Company documents (and all copies thereof) and other Company property then in existence that you have had in your possession at any time, including, but not limited to, Company files, notes, drawings, records,
business plans and forecasts, financial information, specifications, computer-recorded information, tangible property (including, but not limited to, computers), credit cards, entry cards, identification badges and keys; and, any materials of any

 THIS WARRANT HAS BEEN, AND THE COMMON STOCK WHICH MAY BE PURCHASED PURSUANT TO THE EXERCISE OF THIS WARRANT (THE
“WARRANT SHARES,” AND TOGETHER WITH THIS WARRANT, THE “SECURITIES”) WILL BE, ISSUED PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SECTION 1145 OF THE BANKRUPTCY REFORM ACT OF 1978, AS AMENDED (THE
“BANKRUPTCY CODE”). THE SECURITIES MAY BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED WITHOUT REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), PROVIDED THAT THE HOLDER IS NOT
DEEMED TO BE AN UNDERWRITER AS SUCH TERM IS DEFINED IN SECTION 1145(b) OF THE BANKRUPTCY CODE. IF THE HOLDER IS DEEMED TO BE AN UNDERWRITER AS SUCH TERM IS DEFINED IN SECTION 1145(b) OF THE BANKRUPTCY CODE, THEN THE SECURITIES MAY NOT BE SOLD,
OFFERED FOR SALE, PLEDGED OR HYPOTHECATED UNLESS (1) THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAW OR (2) THE COMPANY IS IN RECEIPT OF AN OPINION OF COUNSEL SATISFACTORY TO
THE COMPANY AND ITS COUNSEL THAT SUCH DISPOSITION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE SECURITIES ACT AND OF ANY APPLICABLE STATE SECURITIES LAWS. THIS WARRANT MUST BE SURRENDERED TO THE COMPANY OR ITS TRANSFER
AGENT AS A CONDITION PRECEDENT TO THE SALE, PLEDGE OR OTHER TRANSFER OF ANY INTEREST IN ANY OF THE WARRANT SHARES REPRESENTED BY THIS WARRANT. 

THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT SHALL ALSO BE SUBJECT TO AN INVESTOR RIGHTS AGREEMENT DATED AS OF JUNE 22, 2012 AMONG HMH HOLDINGS
(DELAWARE), INC. AND ITS STOCKHOLDERS (AS AMENDED FROM TIME TO TIME) (THE “INVESTOR RIGHTS AGREEMENT”). A COPY OF SUCH AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST. 

 WARRANT TO PURCHASE SHARES OF COMMON STOCK, PAR VALUE $0.01 PER SHARE, OF 

HMH HOLDINGS (DELAWARE), INC. 
 This warrant certificate (the “Warrant Certificate”) certifies that
[                                        ]
or its registered assigns (the “Holder”) is the owner of [            ] Warrants (the “Warrants”), each of which entitles the Holder to purchase
from HMH HOLDINGS (DELAWARE), INC., a Delaware corporation (the “Company”), one fully paid, duly authorized and non-assessable share of Common Stock, par value $0.01 per share, of the Company (the “Common Stock”), at any
time or from time to time on or before 5:00 p.m., New York City time, on June 22, 2019, at an exercise price of $42.27 per share (subject to adjustment in Section 2, the “Exercise Price”), all on the terms and
subject to the conditions hereinafter set forth. 
 The number of shares of Common Stock issuable upon exercise of each such
Warrant (the “Number Issuable”), which is initially one (1) share of Common Stock, is subject to adjustment from time to time pursuant to the provisions of Section 2 of this Warrant Certificate. 

Capitalized terms used herein but not otherwise defined shall have the meanings given them in Section 11 hereof. 

Section 1. Exercise of Warrant. Subject to the last paragraph of this Section 1 and Section 6(b) hereof,
the Warrants evidenced hereby may be exercised, in whole or in part, by the Holder at any time or from time to time on or before 5:00 p.m., New York City time, on June 22, 2019 (the “Exercise Period”), upon delivery to the
Company at the registered office of the Company, of: (a) this Warrant Certificate, (b) a written notice stating that such holder elects to exercise the Warrants evidenced hereby in accordance with the provisions of this
Section 1 and specifying the name or names in which such holder wishes the certificate or certificates for shares of Common Stock to be issued (if certificated) and (c) payment of the Exercise Price for the shares of Common Stock
issuable upon exercise of such Warrants. Such Exercise Price shall be payable (i) by wire transfer or a certified or official bank check payable to the order of the Company or (ii) by the surrender (which surrender shall be evidenced by
cancellation of the number of Warrants represented by any Warrant certificate presented in connection with a Cashless Exercise (as defined below)) of a Warrant or Warrants (represented by one or more relevant Warrant certificates), and without the
payment of the Exercise Price in cash, in return for the delivery to the surrendering holder of that number of shares of Common Stock equal to (A) the number shares of Common Stock for which such Warrant is exercisable as of the date of
exercise (if the Exercise Price were being paid in cash, wire transfer or certified or official bank check) reduced by (B) that number of shares of Common Stock equal to the quotient obtained by dividing (x) the aggregate Exercise Price to
be paid by (y) the Market Price of one share of Common Stock on the Business Day which next precedes the day of exercise of the Warrant. An exercise of a Warrant in accordance with clause (iii) is herein referred to as a “Cashless
Exercise.” The documentation and consideration, if any, delivered in accordance with subsections (a), (b) and (c) are collectively referred to herein as the “Warrant Exercise Documentation.” 

As promptly as practicable, and in any event within five Business Days after receipt of the Warrant Exercise Documentation, the Company
shall: (a) (i) to the extent that the Company’s transfer agent (the “Transfer Agent”) is participating in The Depositary Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the
request of the Holder of the Warrants, credit such aggregate number of shares of Common Stock to which such holder 

 
is entitled pursuant to such exercise to such holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or (ii) deliver or cause
to be delivered, if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, the certificates, if certificated, representing the number of validly issued, fully paid and non-assessable shares of Common Stock
properly specified in the Warrant Exercise Documentation, (b) if applicable, deliver or caused to be delivered cash in lieu of any fraction of a share of Common Stock, as hereinafter provided, and (c) if less than the full number of
Warrants evidenced hereby are being exercised, deliver or caused to be delivered a new warrant certificate or certificates, of like tenor, for the number of Warrants evidenced by this Warrant Certificate, less the number of Warrants then being
exercised. Such exercise shall be deemed to have been made at the close of business on the date of delivery of all of the Warrant Exercise Documentation so that, to the extent permitted by applicable law, the Person entitled to receive shares of
Common Stock upon such exercise shall be treated for all purposes as having become the record holder of such shares of Common Stock at such time. No such surrender shall be effective to constitute the Person entitled to receive such shares of Common
Stock as the record holder thereof while the transfer books of the Company for Common Stock are closed for any purpose (but not for any period in excess of five days), but any such surrender of this Warrant Certificate for exercise during any period
while such books are so closed shall become effective for exercise immediately upon the reopening of such books, as if the exercise had been made on the date this Warrant Certificate was surrendered and for the Number Issuable of shares of Common
Stock specified in the Warrant Exercise Documentation and at the Exercise Price. 
 Any exercise of the Warrants evidenced
hereby may be conditioned by the Holder of such Warrants on any event or the consummation of any transaction, including a sale of the Company, a public offering or a sale of shares of Common Stock underlying these Warrants. Any exercise so
conditioned shall not be deemed to have occurred except concurrently with the consummation of such transaction or event, except that, for purposes of determining whether such exercise is timely, it shall be deemed to have occurred on the date such
Warrant or Warrants were surrendered to the Company. The holder may rescind the exercise of the Warrant or Warrants at any time prior to the consummation of such transaction or event. 

The Company shall pay all expenses in connection with, and all taxes and other governmental charges (other than income taxes of the
Holder) that may be imposed in respect of, the issue or delivery of any shares of Common Stock issuable upon the exercise of the Warrants evidenced hereby. The Company shall not be required, however, to pay any tax or other charge imposed in
connection with any transfer involved in the issue of any shares of Common Stock in any name other than that of the Holder. 

In connection with the exercise of any Warrants evidenced hereby, no fractions of shares of Common Stock shall be issued, but in lieu
thereof the Company shall pay a cash adjustment in respect of such fractional interest in an amount equal to such fractional interest multiplied by the Market Price of a share of Common Stock on the Business Day which next precedes the day of
exercise. If more than one such Warrant shall be exercised by the Holder thereof at the same time, the number of full shares of Common Stock issuable on such exercise shall be computed on the basis of the total number of Warrants so exercised.

 Section 2. Adjustments. 
 (a) Adjustment of Number Issuable. The Number Issuable shall be subject to adjustment from time to time as follows: 

  
 2 

 (i) In case the Company shall at any time or from time to time after the Issue Date:

 (A) pay a dividend or make a distribution on the outstanding shares of Common Stock in capital stock of the Company;

 (B) forward split or subdivide the outstanding shares of Common Stock into a larger number of shares; 

(C) reverse split or combine the outstanding shares of Common Stock into a smaller number of shares; or 

(D) issue any capital stock of the Company in a reclassification of the shares of Common Stock; 

then, and in each such case (A) through (D), (I) the Number Issuable in effect immediately prior to such event shall be adjusted (and any other
appropriate actions shall be taken by the Company) so that the Holder of any Warrant evidenced hereby thereafter exercised shall be entitled to receive the number of shares of Common Stock or other securities of the Company which such Holder would
have owned or had been entitled to receive upon or by reason of any of the events described above, had such Warrant been exercised immediately prior to the happening of such event and (II) the Exercise Price shall be adjusted to be equal to the
product of (x) the Exercise Price immediately prior to the occurrence of such event and (y) a fraction (1) the numerator of which is the number of shares of Common Stock issuable upon exercise of such Warrant immediately prior to the
adjustment in Section 2(a)(i)(I) above and (2) the denominator of which is the number of shares of Common Stock issuable upon exercise of such Warrant immediately after the adjustment in Section 2(a)(i)(I) above. An
adjustment made pursuant to this Section 2(a)(i) shall become effective retroactively (x) in the case of any such dividend or distribution, to a date immediately following the close of business on the record date for the
determination of holders of shares of Common Stock entitled to receive such dividend or distribution, or (y) in the case of any such split, subdivision, combination or reclassification, to the close of business on the date upon which such
corporate action becomes effective. 
 (ii) In case the Company shall at any time or from time to time after the Issue Date
distribute to any holder of shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the resulting or surviving corporation and the Common Stock is not changed or exchanged)
cash, evidences of indebtedness of the Company or another issuer, securities of the Company or another issuer or other assets (excluding dividends or other distributions of shares of Common Stock or other capital stock for which adjustment is made
under Section 2(a)(i)) or rights or warrants to subscribe for or purchase securities of the Company or another issuer (excluding those in respect of which adjustments in the Number Issuable is made pursuant to
Section 2(a)(i)) (each, a “Distribution”), then, and in each such case, the Exercise Price shall be decreased, effective immediately after the effective date of such Distribution, by the amount of cash and/or the Market
Price of any securities or Fair Market Value of any other property or assets (as reasonably determined in good faith by the board of directors of the Company) paid or distributed on each share of Common Stock (or other securities) in respect of such
Distribution. Such adjustment shall be made whenever any such Distribution is made and shall become effective retroactively to a date immediately following the close of business on the record date for the determination of stockholders entitled to
receive such Distribution. 

  
 3 

 (iii) In case the Company at any time or from time to time shall take any action which
would have a dilutive effect on the number of shares of Common Stock that may be issued upon exercise of the Warrants, other than an action described above, then the Number Issuable shall be adjusted in such manner and at such time as the board of
directors of the Company reasonably determines to be equitable under the circumstances (such determination to be evidenced in a resolution, a certified copy of which shall be mailed to the Holder). 

(iv) Notwithstanding anything herein to the contrary, no adjustment under this Section 2(a) need be made to the Number
Issuable unless such adjustment would require an increase or decrease of at least 1% of the Number Issuable then in effect. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent
adjustment, which, together with any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1% of such Number Issuable. Any adjustment to the Number Issuable carried forward and not theretofore made shall
be made immediately prior to the exercise of any Warrants pursuant hereto. 
 (v) The Company shall deliver to the Holder
promptly following the occurrence of any event or the consummation of any transaction which would result in an increase or decrease in the Number Issuable pursuant to this Section 2 a notice thereof, together with a certificate, signed
by the Chief Executive Officer or a Vice-President and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary of the Company, setting forth in reasonable detail the event or transaction requiring the adjustment and the
method by which such adjustment was calculated and specifying the increased or decreased Number Issuable then in effect following such adjustment. 
 (vi) Notwithstanding anything to the contrary contained in this Section 2(a), the Company shall be entitled to make such upward adjustments in the Number Issuable, in addition to those
otherwise required by this Section 2(a), as the board of directors of the Company in its discretion shall determine to be advisable in order that any stock dividend, split, subdivision or combination of shares, distribution of rights or
warrants to purchase shares, stock or securities or distribution of securities convertible into or exchangeable for shares of Common Stock hereafter made the Company to its stockholders shall not be taxable; provided, however, that any
such adjustment shall treat all Holders of Warrants with similar protections on an equal basis. 
 (b) Reorganization,
Reclassification, Consolidation, Merger or Sale of Assets. In case of any capital reorganization or reclassification or other change of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or
from no par value to par value, or as a result of a split, subdivision or combination), or in case of any consolidation or merger of the Company with or into another Person (other than a consolidation or merger in which the Company is the resulting
or surviving Person and which does not result in any reclassification or change of outstanding Common Stock), or in case of any sale or other disposition to another Person of all or substantially all of the assets of the Company, other than a
sale/leaseback, mortgage or other similar financing transaction (any of the foregoing, a “Transaction”), the Company shall not effect any such Transaction, unless, at the Company’s option, either (A) the Company, or such
successor Person or transferee of the Company, as the case may be, shall make appropriate provision by amendment of the Warrant Agreement or by the successor Person or transferee executing a replacement warrant agreement so that the Holder of each
such Warrant then outstanding shall have the right at any time after the consummation of such Transaction, upon exercise or conversion of the Warrant (in lieu of the number of shares of 

  
 4 

 
Common Stock theretofore deliverable) to only receive the kind and amount of securities, cash and other property receivable upon such Transaction as would be received by a Holder of the number of
shares of Common Stock issuable upon exercise or conversion of the Warrant immediately prior to such Transaction or (B) simultaneously with the consummation of a Transaction, the Company shall redeem the Warrants and pay to each Holder, upon
surrender of this Warrant to the Company, in the same form of consideration as is received by Holders of Common Stock in such Transaction, an amount equal to the greater of: (I) the Fair Market Value of this Warrant and (II) the positive
difference between (y) the consideration that would be received upon such consummation by a Holder of the number of shares of Common Stock deliverable (immediately prior to such consummation) upon exercise of such Warrants and (z) the
aggregate Exercise Price therefor. The provisions of this Section 2(b) similarly shall apply to successive Transactions. 
 Section 3. Notice of Certain Events. In case at any time or from time to time the Company shall declare any dividend or any other distribution to the Holders of its shares of Common Stock, or shall
authorize the granting to the Holders of its shares of Common Stock of rights or warrants to subscribe for or purchase any additional shares of any class or any other right, or shall authorize the issuance or sale of any other shares or rights which
would result in an adjustment to the Number Issuable, or there shall be any Transaction, then, in any one or more of such cases, the Company shall mail to each Holder at such Holder’s address as it appears on the transfer books of the Company,
as promptly as practicable but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (a) the date on which a record is to be taken for the purpose of such dividend, distribution, rights or warrants
or, if a record is not to be taken, the date as of which the holders of the shares of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined, (b) the date of issuance of such shares or
rights or (c) the date on which such Transaction is expected to become effective; provided, that in the case of any event to which Section 2(b) applies, the Company shall give at least ten Business Days’ prior written
notice as aforesaid. In case of any event described in Section 2(b), such notice also shall specify the date as of which it is expected that the holders of the shares of Common Stock of record shall be entitled to exchange their shares
of Common Stock for shares, stock or other securities or property or cash deliverable upon such reorganization, reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up. 

Section 4. Certain Covenants. 
 (a) Authorized Shares. The Company covenants and agrees that all shares of capital stock of the Company which may be issued upon the exercise of the Warrants evidenced hereby will be duly
authorized, validly issued and fully paid and non-assessable upon issuance and will be free and clear of all liens and will not be subject to any pre-emptive or similar rights. The Company shall at all times reserve and keep available solely for
issuance upon the exercise of the Warrants, such number of its authorized but unissued shares of Common Stock as will from time to time be sufficient to permit the exercise of all outstanding Warrants, and shall take all action required to increase
the authorized number of shares of Common Stock if at any time there shall be insufficient authorized but unissued shares of Common Stock to permit such reservation or to permit the exercise of all outstanding Warrants. 

(b) No Impairment. The Company will not, by amendment of its charter or through reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the

  
 5 

 
carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder of this Warrant against impairment. Without
limiting the generality of the foregoing, the Company will (i) not increase the par value of any shares of Common Stock obtainable upon the exercise of this Warrant and (ii) take all such actions as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of this Warrant. 
 Section 5. Registered Holder. The person in whose name this Warrant Certificate is registered shall be deemed the owner hereof and of the Warrants evidenced hereby for all purposes. The Holder of
this Warrant Certificate, in its capacity as such, shall not be entitled to any rights whatsoever as a stockholder of the Company, except as herein provided. 
 Section 6. Certain Transfer and Exercise Provisions. 
 (a) Transfer
Provisions. Any transfer of the rights represented by this Warrant Certificate shall be effected by the surrender of this Warrant Certificate, along with the form of assignment attached hereto, properly completed and executed by the Holder
hereof, at the registered office of the Company. Thereupon, the Company shall issue in the name or names specified by the Holder hereof and, in the event of a partial transfer, in the name of the Holder hereof, a new warrant certificate or
certificates evidencing the right to purchase such number of shares of Common Stock as shall be equal to the then applicable Number Issuable. 
 (b) Transfer Documentation. So long as the Investor Rights Agreement remains in effect, any transferee may only exercise the Warrants upon such transferee’s execution and delivery of a joinder
to the Investor Rights Agreement unless such transferee is already a party to the Investor Rights Agreement. 
 Section 7.
Denominations. The Company covenants that it will, at its expense, promptly upon surrender of this Warrant Certificate at the registered office of the Company, execute and deliver to the Holder a new warrant certificate or certificates in
denominations specified by such Holder for an aggregate number of Warrants equal to the number of Warrants evidenced by this Warrant Certificate. 
 Section 8. Replacement of Warrants. Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant Certificate and, in the case of loss, theft or
destruction, upon delivery of an indemnity reasonably satisfactory to the Company and the Transfer Agent (in the case of an institutional investor, its own unsecured indemnity agreement shall be deemed to be reasonably satisfactory), or, in the case
of mutilation, upon surrender and cancellation thereof, the Company will issue a new warrant certificate of like tenor for a number of Warrants equal to the number of Warrants evidenced by this Warrant Certificate. 

Section 9. Governing Law. THIS WARRANT CERTIFICATE SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF THE
PARTIES SHALL BE GOVERNED BY, THE LAWS OF THE STATE OF DELAWARE APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE. 
 Section 10. Rights Inure to Registered Holder. The Warrants evidenced by this Warrant Certificate will inure to the benefit of and be binding upon the Holder and the Company and their respective
successors and permitted assigns. Nothing in this Warrant Certificate shall be construed to give to any Person other than the Company and the Holder any legal or equitable 

  
 6 

 
right, remedy or claim under this Warrant Certificate, and this Warrant Certificate shall be for the sole and exclusive benefit of the Company and such Holder. Nothing in this Warrant Certificate
shall be construed to give the Holder any rights as a holder of shares of Common Stock until such time, if any, as the Warrants evidenced by this Warrant Certificate are exercised in accordance with the provisions hereof. 

Section 11. Definitions. For the purposes of this Warrant Certificate, the following terms shall have the meanings indicated
