 Exhibit 10.4 
 HMH HOLDINGS (DELAWARE), INC. 
 2012 MANAGEMENT INCENTIVE PLAN

 NON-EMPLOYEE GRANTEE RESTRICTED STOCK UNIT AWARD NOTICE 
 HMH Holdings (Delaware), Incl. (the “Company”) has previously established the HMH Holdings (Delaware), Inc. 2012 Management Incentive Plan (the “Plan”) and, pursuant to
Section 7 thereof, the Company desires to grant to [            ] (the “Grantee”) an award of restricted stock units (the “RSUs”), as of this
[    ] day of [        ], [            ] (the “Grant Date”), subject to the terms and conditions set forth in
this notice (“Award Notice”). 
 1. Award. Subject to the terms and conditions set forth herein and in the Plan,
the Company hereby grants to the Grantee an award (the “Award”) of              restricted stock units (the “RSUs”). The RSUs are subject to the
restrictions described herein, including forfeiture under the circumstances described in Section 4 hereof. 
 2. Restricted Period;
Vesting. 
 (a) General. The Restricted Period with respect to the RSUs shall commence on the Grant Date
and expire on [                    ]. The RSUs shall be 100% unvested on the Grant Date, and except as otherwise provided in Section 4, shall
vest in full on the last day of the Restricted Period, subject to the Grantee’s continuous service as a member of the Board through such date. Notwithstanding the foregoing, the Committee shall have the authority to remove the restrictions on
the RSUs whenever it may determine that, by reason of changes in applicable laws or other changes in circumstances arising after the Grant Date, such action is appropriate. 
 (b) Effect of Termination of Service. In the event the Grantee’s service as a member of the Board terminates by reason of his death or Disability, the outstanding RSUs shall vest on
such date of death or Disability. If the Grantee’s service as a member of the Board is terminated (i) by the Company or the shareholders of the company for “cause” (as determined by the Board in good faith) or (ii) because
the Grantee resigns or refuses reappointment or reelection to the Board, all then outstanding unvested RSUs shall be immediately forfeited. If the Grantee’s service as a member of the Board terminates because he is not reelected or reappointed
to the Board (other than for “cause” and other than due to his refusal to stand for such reelection or reappointment), all then outstanding RSUs shall vest on the date of termination of service. 

(c) Effect of Change in Control. The RSUs shall become 100% vested as of the date of a Change in Control, subject to the
Grantee’s continuous service as a member of the Board through the effective date of such Change in Control. 
 3. Settlement.
On or within 30 days after the RSUs become vested (as applicable, the “Vesting Date”), the vested RSUs shall be “settled” by delivery from the Company to the Grantee, or his or her beneficiary, without charge, of one share
of Common Stock for each outstanding vested RSU; provided, however, that the Committee may, in its sole discretion, elect to pay cash or part cash and part shares of Common Stock in lieu of delivering only shares of Common Stock as
settlement for such vested RSUs. Any cash 

 
payment made hereunder in lieu of delivery of a share of Common Stock shall be equal to the Fair Market Value of a share of Common Stock as of the Vesting Date, less any income and employment
taxes required to be withheld on such payment. Shares of Common Stock issued in respect of vested RSUs may be evidenced by delivery to the Grantee of either a certificate or certificates therefor or written evidence of the book entry notification
evidencing the issuance thereof, registered in the Grantee’s name. Notwithstanding the foregoing, the payment dates set forth in this Section 3 have been specified for the purpose of complying with the provisions of Section 409A of
the Code (“Section 409A”). To the extent payments are made during the periods permitted under Section 409A (including any applicable periods before or after the specified payment dates set forth in this Section 3), the
Company shall be deemed to have satisfied its obligations under the Plan and shall be deemed not to be in breach of its payments obligations hereunder. 
 4. Rights as a Shareholder. The Grantee shall have no rights as shareholder with respect to the shares of Common Stock subject to the Award until the Grantee shall have become the holder of
record of such shares, and except as provided in Section 3.2 of the Plan, no adjustment shall be made for dividends or distributions or other rights in respect of such shares for which the date on which shareholders of record are determined for
purposes of paying cash dividends on shares of Common Stock is prior to the date upon which the Grantee shall become the holder of record thereof. 
 5. Tax Withholding. The Company shall have the right to require, prior to the issuance or delivery of any shares of Common Stock or the payment of any cash pursuant to the Award made
hereunder, payment by the Grantee of any federal, state, local or other taxes that may be required to be withheld or paid in connection with such Award. At the sole discretion of the Committee, the Grantee may satisfy such withholding obligation
(a) by allowing the Company to withhold whole shares of Common Stock that would otherwise be delivered to the Grantee, having an aggregate Fair Market Value, determined as of the date the obligation to withhold or pay, equal to the minimum
withholding taxes required in connection with the Award or by allowing the Company to withhold an amount of cash that would otherwise be payable to the Grantee, in the amount necessary to satisfy any such obligation; (b) by paying such
obligation in cash; (c) by delivering shares of Common Stock (that are Mature Shares) or (d) by any combination of the foregoing. 

6. Non-Transferability. The Award is subject to the restrictions on transferability set forth in Section 9.3 of the Plan. 

7. Adjustments. The Award granted hereunder is subject to adjustment pursuant to Section 3.2 of the Plan. 

8. Repurchase Rights. The provisions of Article X of the Plan shall not apply to any shares of Common Stock issued in respect of the RSUs.

 9. Applicable Securities Laws. Shares of Common Stock issued pursuant to the Award granted under this Award Notice shall not be
sold or transferred unless either they 

  
 2 

 
first shall have been registered under the Securities Act or upon request by the Company, the Company first shall have been furnished with an opinion of legal counsel, reasonably satisfactory to
the Company, to the effect that such sale or transfer is exempt from the registration requirements of the Securities Act.

Company at its principal executive office, and all notices or communications by the Company to the Grantee may be given to the Grantee personally or may be mailed to the Grantee’s address as recorded in the records of the Company or any
Subsidiary.

Delaware without regard to its conflict of law principles.

 15.
Severability. Every provision of this Award Notice is intended to be severable and any illegal or invalid term shall not affect the validity or legality of the remaining terms.

substantially in the form attached hereto as Schedule A that has become irrevocable and effective in accordance with its terms. 

2.8 Restricted Covenant Obligations Unaffected. Each Eligible Employee shall remain subject to any existing non-competition,
non-solicitation, non-disparagement, confidentiality or other restrictive covenant obligations applicable to such Eligible Employee in accordance with their terms, which shall remain unaffected by this Plan.

Administrator that are not inconsistent with the provisions of the Plan. 
 SECTION 4. EXCISE TAX CUTBACK. 

4.1 In the event it shall be determined (as hereafter provided) that any payment or distribution whether paid or payable or distributed
or distributable pursuant to the terms of this Plan or otherwise pursuant to or by reason of any other agreement, policy, plan, program or arrangement (including without limitation payments or acceleration of vesting in respect of any equity-based
or other award), or similar right (collectively, a “Payment”), to or for the benefit of an Eligible Employee, would be subject to the excise tax imposed by Section 4999 of the Code, or any successor provision thereto, or any
similar tax imposed by state or local law, or any interest or penalties with respect to such excise tax (such tax or taxes, together with any such interest and penalties, 

  
 6 

 
are hereafter collectively referred to as the “Excise Tax”), then the aggregate amount of the Payment payable to the Eligible Employee shall be reduced to the Safe Harbor Amount,
but only if such reduction would result in a greater net payment to the Eligible Employee than he or she would have received without such reduction but after paying the Excise Tax. 

4.2 All determinations required to be made under this Section 4 will be made by a nationally recognized firm of certified public
accountants (the “Accounting Firm”) designated by the Company prior to a Change in Control and reasonably acceptable to the Eligible Employee. Any determination by the Accounting Firm will be binding upon the Company and the
Eligible Employee. 
 4.3 The fees and expenses of the Accounting Firm for its services in connection with the determinations

Severances that occur prior to the date of the termination of the Plan. 
 5.2 The Plan may not be amended or terminated in a
way adverse to participants in the Plan, and participants may not be removed from Plan participation, in either case following the occurrence of a Change in Control or the entry into a definitive agreement (or commencement of an action) the
consummation of which would result in a Change in Control. Subject to the foregoing, participants may be removed from Plan participation only on one year’s advance written notice. 
 SECTION 6. GENERAL PROVISIONS. 
 6.1 Except as otherwise provided herein or
by law, no right or interest of any Eligible Employee under the Plan shall be assignable or transferable, in whole or in part, either directly or by operation of law or otherwise, including without limitation by execution, levy, garnishment,
attachment, pledge or in any manner; no attempted assignment or transfer thereof shall be effective; and no right or interest of any Eligible Employee under the Plan shall be liable for, or subject to, any obligation or liability of such Eligible
Employee. When a payment is due under this Plan to a terminated participant who is unable to care for his or her affairs, payment may be made directly to his or her legal guardian or personal representative. 

6.2 If the Company or any subsidiary thereof is obligated by law or by contract to pay severance pay, a termination indemnity, notice
pay, or the like, or if the Company or any subsidiary thereof is obligated by law to provide advance notice of separation (“Notice Period”), then any severance pay hereunder shall be reduced by the amount of any such severance pay,
termination indemnity, notice pay or the like, as applicable, and by the amount of any compensation received during any Notice Period. 

  
 7 

 6.3 Neither the establishment of the Plan, nor any modification thereof, nor the creation of
any fund, trust or account, nor the payment of any benefits shall be construed as giving any Eligible Employee, or any person whomsoever, the right to be retained in the service of the Company or any subsidiary thereof, and all Eligible Employees
shall remain subject to discharge to the same extent as if the Plan had never been adopted. 
 6.4 If any provision of this Plan
shall be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provisions hereof, and this Plan shall be construed and enforced as if such provisions had not been included. 

6.5 This Plan shall inure to the benefit of and be binding upon the heirs, executors, administrators, successors and assigns of the
parties, including each Eligible Employee, present and future, and any successor to the Company. If a terminated participant shall die while any amount would still be payable to him or her hereunder if he or she had continued to live, all such
amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Plan to the executor, personal representative or administrators of the terminated participant’s estate. 

6.6 The headings and captions herein are provided for reference and convenience only, shall not be considered part of the Plan, and shall
not be employed in the construction of the Plan. 
 6.7 The Plan shall not be required to be funded unless such funding is
authorized by the Board. Regardless of whether the Plan is funded, no Eligible Employee shall have any right to, or interest in, any assets of any Company which may be applied by the Company to the payment of benefits or other rights under this
Plan. 
 6.8 Any notice or other communication required or permitted pursuant to the terms hereof shall have been duly given
when delivered or mailed by United States Mail, first class, postage prepaid, addressed to the intended recipient at his, her or its last known address. 
 6.9 This Plan shall be construed and enforced according to the laws of the State of Delaware to the extent not preempted by federal law, which shall otherwise control. 

6.10 All benefits hereunder shall be reduced by applicable tax withholding and shall be subject to applicable tax reporting, as
determined by the Plan Administrator. 
 6.11 For purposes of Section 409A of the Code and the regulations and guidance
promulgated thereunder (“Section 409A”), each of the payments that may be made under the Agreement are designated as separate payments. It is intended that the provisions of the Agreement comply with Section 409A, and all
provisions of the 

  
 8 

 
Agreement shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A. Notwithstanding the foregoing, an Eligible
Employee shall be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on or for his or her account in connection with this Plan (including any taxes and penalties under Section 409A), and neither
the Company nor any Affiliate shall have any obligation to indemnify or otherwise hold the Eligible Employee (or any beneficiary) harmless from any or all of such taxes or penalties. Notwithstanding anything in this Plan to the contrary, in the
event that an Eligible Employee is deemed to be a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, no payments that are “deferred compensation” subject to Section 409A that are made by
reason of his or her “separation from service” within the meaning of Section 409A shall be made to the Eligible Employee prior to the date that is six months after the date of his or her “separation from service” or, if
earlier, his or her date of death. Immediately following any applicable six-month delay, all such delayed payments will be paid in a single lump sum. In addition, for purposes of this Plan, with respect to payments of any amounts that are considered
to be “deferred compensation” subject to Section 409A, references to “termination of employment” (and substantially similar phrases) shall be interpreted and applied in a manner that is consistent with the requirements of
Section 409A. Except as permitted under Section 409A, any deferred compensation that is subject to Section 409A and is payable to or for an Eligible Employee’s benefit under any Company-sponsored plan, program, agreement or
arrangement may not be reduced by, or offset against, any amount owing by such Eligible Employee to the Company or any Affiliate.

 7.2 Denial of Claims. In the event that any application for benefits is denied in whole or in part, the Plan Administrator must notify the applicant, in writing, of the denial of the application,
and of the applicant’s right to review the denial. The written notice of denial will be set forth in a manner designed to be understood by the employee, and will include specific reasons for the denial, specific references to the Plan provision
upon which the denial is based, a description of any information or material that the Plan Administrator needs to complete the review and an explanation of the Plan’s review procedure. 
 This written notice will be given to the employee within ninety (90) days after the Plan Administrator receives the application, unless special circumstances require an extension of time, in which
case, the Plan Administrator has up to an additional ninety (90) days for 

  
 9 

 
processing the application. If an extension of time for processing is required, written notice of the extension will be furnished to the applicant before the end of the initial ninety (90)-day
period. 
 This notice of extension will describe the special circumstances necessitating the additional time and the date by which the Plan
Administrator is to render his or her decision on the application. If written notice of denial of the application for benefits is not furnished within the specified time, the application shall be deemed to be denied. The applicant will then be
permitted to appeal the denial in accordance with the Review Procedure described below. 
 7.3 Request for a Review. Any
person (or that person’s authorized representative) for whom an application for benefits is denied (or deemed denied), in whole or in part, may appeal the denial by submitting a request for a review to the Plan Administrator within 60 days
after the application is denied (or deemed denied). The Plan Administrator will give the applicant (or his or her representative) an opportunity to review pertinent documents in preparing a request for a review and submit written comments,
documents, records and other information relating to the claim. A request for a review shall be in writing and shall be addressed to: 
 HMH Holdings (Delaware), Inc.

Attn: CIC Severance Plan Administrator 
 A request for review must set forth all of the grounds on which it is based, all facts in support of the request and any other matters that the applicant feels are pertinent. The Plan Administrator may
require the applicant to submit additional facts, documents or other material as he or she may find necessary or appropriate in making his or her review. 
 7.4 Decision on Review. The Plan Administrator will act on each request for review within sixty (60) days after receipt of the request, unless special circumstances require an extension of
time (not to exceed an additional sixty (60) days), for processing the request for a review. If an extension for review is required, written notice of the extension will be furnished to the applicant within the initial sixty (60)-day period.
The Plan Administrator will give prompt, written notice of his or her decision to the applicant. In the event that the Plan Administrator confirms the denial of the application for benefits in whole or in part, the notice will outline, in a manner
calculated to be understood by the applicant, the specific Plan provisions upon which the decision is based. If written notice of the Plan Administrator’s decision is not given to the applicant within the time prescribed in this
Section 7.4 the application will be deemed denied on review. 
 7.5 Rules and Procedures. The Plan Administrator may
establish rules and procedures, consistent with the Plan and with ERISA, as necessary and appropriate in carrying out his or her responsibilities in reviewing benefit claims. The Plan Administrator may require an applicant who wishes to submit
additional information in connection with an appeal from the denial (or deemed denial) of benefits to do so at the applicant’s own expense.

 7.6 Exhaustion of Remedies. No legal action for benefits under the Plan may be
brought until the claimant (a) has submitted a written application for benefits in accordance with the procedures described by Section 7.1 above, (b) has been notified by the Plan Administrator that the application is denied (or the
application is deemed denied due to the Plan Administrator’s failure to act on it within the established time period), (c) has filed a written request for a review of the application in accordance with the appeal procedure described in
Section 7.3 above and (d) has been notified in writing that the Plan Administrator has denied the appeal (or the appeal is deemed to be denied due to the Plan Administrator’s failure to take any action on the claim within the time
prescribed by Section 7.4 above).

compensation and benefits under the Plan to which the Executive would not otherwise be entitled (in the absence of the Executive’s delivery of this waiver and release of claims ), the Executive, for and on behalf of himself/herself and his/her
heirs and assigns, hereby waives and releases any common law, statutory or other complaints, claims, charges or causes of action arising out of or relating to the Executive’s employment or termination of employment with, or his/her serving in
any capacity in respect of, the Company or any of its subsidiaries or affiliates (the “Company Group”), both known and unknown, in law or in equity, which the Executive may now have or ever had against any member of the Company
Group or any shareholder, partner, member, employee, director, manager, agent or officer of any member of the Company Group (collectively, the “Releasees”) from the beginning of time to the date hereof. This includes, but is not
limited to (i) any claim for any severance benefit which but for this Agreement might have been due the Executive under any previous agreement executed by and between any member of the Company Group and the Executive or any other severance
plan, including the Basic Severance Plan; (ii) any discrimination claim based on race, religion, color, national origin, age, sex, sexual orientation or preference, disability, military service or other protected class, or retaliation;

may have against the Releasees under these and any other laws. 
  

	1 	This release is subject to modification as may be needed to reflect specific applicable state laws and enforceability requirements. 

 Notwithstanding the foregoing, all of the Executive’s rights to
(i) indemnification under the By-Laws, any indemnification agreement or arrangement entered into between the Executive and any member of the Company Group and/or Charter or Certificate of Incorporation of any member of the Company Group;
(ii) the payments and benefits under the Plan; (iii) accrued vested benefits under employee benefit plans of the Company Group subject to the terms and conditions of such plans and applicable law; (iv) coverage under the

 The Executive acknowledges that he/she has not filed any complaint, charge, claim or proceeding against any of the Releasees
before any local, state or federal agency, court or other body relating to his/her employment or the termination thereof (each individually a “Proceeding”). The Executive represents that he/she is not aware of any basis on which
such a Proceeding could reasonably be instituted. The Executive (i) acknowledges that he/she will not initiate or cause to be initiated on his/her behalf any Proceeding and will not participate in any Proceeding, in each case, except as
required by law; and (ii) waives any right he/she may have to benefit in any manner from any relief (whether monetary or otherwise) arising out of any Proceeding, including any Proceeding conducted by the Equal Employment Opportunity Commission
(“EEOC”). Further, except as specifically provided in this paragraph and the immediately preceding paragraph, the Executive understands that by entering into this Agreement, he/she will be limiting the availability of any remedies
that he/she may have against the Company Group and also limiting his/her ability to pursue any claims against the Releasees. Notwithstanding the above, nothing in this Agreement shall prevent the Executive from (i) initiating or causing to be
initiated on his/her behalf any Proceeding against the Company Group before any local, state or federal agency, court or other body challenging the validity of the waiver of his/her claims under ADEA contained in this Agreement (but no other portion
of such waiver), or (ii) initiating or participating in an investigation or Proceeding conducted by the EEOC. 
 The
Executive acknowledges that he/she has been given [twenty-one (21)] [forty-five (45)] days from the date of receipt of this Agreement to consider all the provisions of this Agreement and, if he/she executes this Agreement prior to the expiration of

HE/SHE MAY HAVE TO SUE OR ASSERT A CLAIM AGAINST ANY OF THE RELEASEES, AS DESCRIBED IN THIS AGREEMENT; HE/SHE DOES NOT WAIVE CLAIMS UNDER THE ADEA THAT MAY ARISE AFTER THE DATE EXECUTIVE SIGNS
THIS AGREEMENT; AND THE CONSIDERATION GIVEN BY THE COMPANY FOR THE WAIVER OF RIGHTS AND RELEASE OF CLAIMS IS IN ADDITION TO ANYTHING OF VALUE TO WHICH THE EXECUTIVE IS ALREADY ENTITLED . THE EXECUTIVE ACKNOWLEDGES THAT HE/SHE HAS NOT BEEN FORCED OR
PRESSURED IN ANY MANNER WHATSOEVER TO SIGN THIS AGREEMENT AND THE EXECUTIVE AGREES TO ALL OF ITS TERMS VOLUNTARILY. 
 The
Executive shall have seven (7) days from the date of his/her execution of this Agreement to revoke this Agreement (including without limitation the waiver of rights and release of any ADEA claims covered by this Agreement) by providing a
signed, written notice of the decision to revoke to the Executive’s Human Resources representative. If not so revoked during such seven-day period, this Agreement shall become effective on the eighth (8th) day following the
Executive’s execution of this (the “Effective Date”). If the Executive revokes this Agreement (including without limitation the waiver of rights and release of any ADEA claims covered by this Agreement), the Executive will be
deemed not to have accepted any of the terms of this Agreement, and the Executive will not be entitled to any compensation or benefits under the Plan or any other severance plan, including the Basic Severance Plan, that were conditioned on the
