HMH HOLDINGS (DELAWARE), INC.

2012 MANAGEMENT INCENTIVE PLAN

TIME-BASED RESTRICTED STOCK UNIT AWARD NOTICE

Houghton Mifflin Harcourt Company (formerly known as HMH Holdings (Delaware), Inc.) (the “Company”) has previously established the HMH Holdings (Delaware), Inc. 2012 Management Incentive Plan (the “Plan”) and, pursuant thereto, the Company desires to grant to the Person identified on Schedule I hereto (the “Grantee”) time-based Restricted Stock Units (“RSUs”) with respect to the Company’s common stock, $0.01 par value per share (“Common Stock”), as of [            ], 2015 (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 that number of RSUs as set forth on Schedule I attached hereto (the “Award”). The Award shall be credited to a separate book-entry account maintained for the Grantee on the books of the Company. The Award shall vest and be settled in accordance with Section 2 hereof.

2. Terms and Conditions.

(a) The Award shall be one hundred percent (100%) unvested as of the Grant Date. Except as otherwise provided in the Plan and this Award Notice, the Award shall vest and become non-forfeitable in equal increments on each of the first, second and third anniversaries of the Grant Date (each, a “Vesting Date”), provided that the Grantee remains in continuous service with the Company or any of its Subsidiaries on the applicable Vesting Date.

(b) Except as otherwise provided in this Section 2, in the event that the Grantee’s continuous service is terminated by the Company or by the Grantee for any reason, the Grantee shall forfeit the unvested Award as of the Grantee’s termination date.

(c) In the event that the Grantee’s continuous service is terminated by the Company due to the Grantee’s Disability or due to the Grantee’s death, the unvested Award shall become immediately fully vested as of the Grantee’s termination date.

(d) Notwithstanding any provision herein to the contrary, (i) if the Committee has made a provision for the substitution, assumption, exchange or other continuation of the Award in connection with a Change in Control, then in the event that the Grantee’s continuous service is terminated by the Company other than for Cause, and other than due to death or Disability (which shall be governed by Section 2(c) above), within one (1) year following the occurrence of the Change in Control, the unvested Award shall become immediately fully vested; or (ii) if the Committee has not made a provision for the substitution, assumption, exchange or other continuation of the Award in connection with a Change in Control, then the unvested Award shall become fully vested immediately prior to the Change in Control.

(e) Within 30 days following each Vesting Date (or, if applicable, an earlier vesting date pursuant to Section 2(c) or 2(d) above, which, in such event, shall also be hereinafter referred to as the “Vesting Date”), the Company shall settle the vested portion of the Award and shall therefore, subject to any required tax withholding and the execution of any required documentation, (i) issue and deliver to the Grantee one share of Common Stock for each RSU (the “RSU Shares”) (and, upon such settlement, the RSUs shall cease to be credited to the account) and (ii) enter the Grantee’s name as a shareholder of record with respect to the RSU Shares on the books of the Company. Alternatively, the Committee may, in its sole discretion, elect to pay cash or part cash and part RSU Shares in lieu of settling the vested RSUs solely in RSU Shares. If a cash payment is made in lieu of delivering RSU Shares, the amount of such payment shall be equal to the Fair Market Value as of the Vesting Date of the RSU Shares less an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld.

(f) Simultaneously with the settlement and delivery of RSU Shares as contemplated by Section 2(e), the Grantee shall be entitled to receive an additional amount (the “Dividend Equivalent Amount”) equal to the product of (i) the cash amount of each per share dividend that was paid by the Company on shares of its Common Stock (“Shares”) on any date that Grantee’s RSUs remained outstanding hereunder (or, in the case of a dividend payable in Shares or other property, the per Share equivalent cash value of such dividend as determined in good faith by the Committee) and (ii) the number of RSU Shares so delivered (or, if the RSUs are not settled exclusively in Shares, the number of RSU Shares that would have been delivered had they been settled exclusively in Shares). The Dividend Equivalent Amount shall be payable in cash or, at the discretion of the Committee, in Shares with an equivalent Fair Market Value on the date of payment. The Company shall establish a bookkeeping methodology to account for the Dividend Equivalent Amount. The Dividend Equivalent Amount shall not bear interest.

(g) The Company shall have the right to require prior to the issuance or delivery of any Shares or the payment of any cash pursuant to the Award, payment by the Grantee of any federal, state, local or other taxes that may be required to be withheld or paid in connection with the Award. At the sole discretion of the Committee, the Grantee may satisfy such withholding obligation (1) by allowing the Company to withhold whole Shares 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; (2) by paying such obligation in cash; (3) by delivering Shares or (4) by any combination of the foregoing (1) through (3).

3. Non-Transferability. The Award is subject to the restrictions on transferability set forth in Section 9.3 of the Plan. In addition, with respect to any RSU Shares delivered upon settlement of the RSUs, the Grantee agrees to comply with any written holding requirement policy adopted by the Company for employees.

4. Rights as Shareholder. The Grantee shall have no rights as shareholder with respect to the Shares subject to the Award unless, until and to the extent that (i) the Company shall have issued and delivered to the Grantee the RSU Shares (via certificates or book entry notation) and (ii) the Grantee’s name shall have been entered as a shareholder of record with respect to such RSU Shares on the books of the Company.

5. Adjustments. The Award is subject to adjustment pursuant to Section 3.2 of the Plan.

6. Applicable Securities Laws.

Every notice or other communication relating to this Award Notice shall be in writing, and shall be mailed to or delivered to the party for whom it is intended at such address as may from time to time be designated by it in a notice mailed or delivered to the other party as herein provided; provided, that, unless and until some other address be so designated, all notices or communications by the Grantee to the Company shall be mailed or delivered to the 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.
