 Exhibit 4.2 
 HMH HOLDINGS (DELAWARE), INC. 
 AMENDED & RESTATED DIRECTOR
NOMINATION AGREEMENT 
 This Amended and Restated Director Nomination Agreement (this “Agreement”)
is made as of August 2, 2013, between HMH Holdings (Delaware), Inc., a Delaware corporation (the “Company”), and the stockholder party hereto (the “Stockholder”). Unless otherwise specified
herein, all of the capitalized terms used herein are defined in Section 4. 
 WHEREAS, the Company entered
into a director nomination agreement with Stockholder dated as of June 22, 2012 (the “Original Nomination Agreement”) pursuant to which the Company agreed to permit the Stockholder who, together with its Affiliates,
Beneficially Owns at least 20% of the issued and outstanding shares of common stock, par value, $0.01 per share, of the Company (the “Common Stock”), to designate one or more persons for nomination for election to the board
of directors of the Company (the “Board”); 
 WHEREAS, the Company and the Stockholder desire to
amend and restate the Original Nomination Agreement in its entirety (and by signing this Agreement the Company and the Stockholder evidence their agreement to do so); 
 WHEREAS, the Company and the Stockholder desire that this Agreement shall only become effective upon the consummation of an Initial Public Offering (the “Effective Time”);

 NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows: 

Section 1. Board of Directors. 
 (a) Subject to the terms and conditions of this Agreement, from and after the Effective Time and until a Holder Nominee Termination Event shall have occurred, the Stockholder shall have the right to
designate one person to be nominated for election to the Board and, if requested by the Stockholder, to designate one person to be appointed or nominated, as the case may be, for election to the board of directors or managers, as the case may be, of
any subsidiary of the Company that is not comprised entirely of employees of the Company or any of its subsidiaries (the “Holder Nominee”). In the case of the Board and the election of directors at an annual meeting of
stockholders, the Stockholder shall designate the Holder Nominee by giving written notice to the Company not later than the 90th day before the anniversary date of the immediately preceding annual meeting of stockholders; provided, that if
the Holder Nominee is not Sheru Chowdhry, then such Holder Nominee shall be selected in consultation with the nominating committee of the Board (the “Nominating Committee”). In connection with any election of directors other
than at an annual meeting of stockholders, the Stockholder and the Company shall cooperate in good faith so that the Stockholder has notice of such election and 45 days to designate its Holder Nominee to stand for election as a director. With
respect to any directly or indirectly wholly-owned subsidiary of the Company, the Company shall take all necessary steps to cause the prompt election or appointment, as the case may be, of such Holder Nominee as a director or manager, as applicable,
of such subsidiary. 

 
With respect to any subsidiary of the Company that is not directly or indirectly wholly-owned by the Company, the Company shall use commercially reasonable efforts to cause the prompt election or
appointment, as the case may be, of such Holder Nominee as a director or manager, as applicable, of such subsidiary. 
 (b)
Subject to the terms and conditions of this Agreement, the Company shall nominate for election or appoint to serve each Holder Nominee designated hereunder by the Stockholder as a member of the Board (a “Director”).

 (c) Notwithstanding anything to the contrary contained herein, if the Stockholder, together with its Affiliates, cease to
Beneficially Own at least 15% of the issued and outstanding shares of Common Stock whether as a result of dilution, Transfer or otherwise, then the rights of the Stockholder under Section 1(a) and all other provisions of this
Section 1 as applicable to the Stockholder’s Holder Nominee shall terminate automatically (each, a “Holder Nominee Termination Event”). Within three Business Days after the occurrence of a Holder Nominee
Termination Event, the Stockholder shall notify the Company of such event. The Stockholder shall cause each Holder Nominee to execute and deliver a resignation prior to becoming a Director which shall be irrevocable and shall be effective with
respect to the Company and any of its subsidiaries for which such Holder Nominee serves as a Director or in a similar capacity automatically upon the occurrence of a Holder Nominee Termination Event and shall not permit any such Holder Nominee to
revoke any such resignation. 
 (d) If a vacancy occurs because of the death, disability, disqualification, resignation or
removal of a Holder Nominee (other than following a Holder Nominee Termination Event), the Stockholder shall be entitled to designate such person’s replacement which replacement shall either be (i) an employee of the Stockholder or
(ii) selected in consultation with the Nominating Committee and such vacancy shall be filled with such replacement Holder Nominee, if a majority of the Board shall vote to approve such replacement Holder Nominee. 

(e) Notwithstanding anything to the contrary in this Agreement, until the occurrence of a Holder Nominee Termination Event, if a Holder
Nominee is not nominated or elected to the Board because of such Holder Nominee’s death, disability, disqualification or withdrawal as a nominee or for any other reason such Holder Nominee is unavailable or unable to serve on the Board, the
Stockholder shall be entitled to designate promptly a replacement Holder Nominee pursuant to the terms and conditions of this Agreement and, subject to Section 2(c), the director position for which such original Holder Nominee was nominated
shall not be filled pending such designation. For the avoidance of doubt, there can be no more than one Holder Nominee on the Board at any time. 
 (f) The Company shall take all necessary action to elect as a Director each replacement Holder Nominee as designated pursuant to Section 1(d) or 1(e). 

(g) The Company shall pay the reasonable out-of-pocket expenses incurred by each Holder Nominee in connection with his services provided
to or on behalf of the Company and/or its subsidiaries, including attending meetings. 

  
 - 2 -

 (h) In accordance with the Company’s By-Laws, the Board shall have certain standing
committees and may from time to time by resolution establish and maintain one or more other committees of the Board, each committee to consist of one or more Directors. If requested by the Stockholder, the Company shall take all necessary steps to
cause the Holder Nominee to be designated as a member of each such committee, and to cause the Holder Nominee to be designated as a member of each committee that the board of directors or managers of any directly or indirectly wholly-owned
subsidiary of the Company may establish and maintain, in each case unless such designation would violate any legal restriction on such committee’s composition or the rules and regulations of any applicable exchange on which the Company’s
securities may be listed. Additionally, to the extent that any subsidiary that is not directly or indirectly wholly-owned by the Company establishes any committee of its board of directors or managers, the Company shall use commercially reasonable
efforts to cause the Holder Nominee to be a member of each such committee, unless such designation would violate any legal restriction on such committee’s composition or the rules and regulations of any applicable exchange on which such
subsidiary’s securities may be listed. 
 (i) The Stockholder shall use its reasonable efforts to cause the Holder Nominee
to comply with the Company’s corporate policies, including, without limitation, its code of ethics, and the Stockholder shall promptly remove any Holder Nominee who fails to comply with such corporate policies after reasonable notice from the
Company. 
 Section 2. Company Obligations. 
 (a) The Company shall take all actions reasonably necessary to ensure that: (i) each Holder Nominee is included in the Board’s slate of nominees to the stockholders for each election of
Directors; (ii) each Holder Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of
Directors, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the election of Directors; and (iii) each replacement Holder Nominee
designated pursuant to Section 1(d) or 1(e) shall be elected as a Director by the Board to fill the related vacancy or as a replacement Holder Nominee, as applicable. 
 (b) Notwithstanding anything herein to the contrary, the Company shall not be obligated to cause to be nominated for election to the Board, recommend to the stockholders the election of any Holder Nominee
or elect or designate a replacement Holder Nominee as a Director to fill any vacancy: (i) who fails to submit to the Company on a timely basis such questionnaires as the Company may reasonably require of its directors generally and such other
information as the Company may reasonably request in connection with the preparation of its filings under the Securities Laws; or (ii) if the Board or the Nominating Committee determines in good faith, after consultation with outside legal
counsel, that such action would constitute a breach of its fiduciary duties or applicable law or violate the Company’s Certificate of Incorporation. Upon the occurrence of either (i) or (ii) above, the Company shall promptly notify
the Stockholder of the occurrence of such event and permit the Stockholder to provide an alternate Holder Nominee sufficiently in advance of any Board action, the meetings of the stockholders called or written action of stockholders with respect to
such election of nominees 

  
 - 3 -

 
and the Company shall use commercially reasonable efforts to perform its obligations under Section 2(a) with respect to such alternate Holder Nominee (provided that if the
Company provides at least 45 days advance notice of the occurrence of any such event such alternative nominee must be designated by the Stockholder not less than 30 days in advance of any Board action, notice of meeting of the stockholders or
written action of stockholders with respect to such election of nominees); and provided, further, that in no event shall the Company be obligated to postpone, reschedule or delay any scheduled meeting of the stockholders with respect to such
election of the Holder Nominee. 
 (c) At any time a vacancy occurs because of the death, disability, disqualification,
resignation or removal of a Holder Nominee, then the Board, or any committee thereof, shall not fill such vacancy until the earlier to occur of: (i) the date that the Stockholder has designated a replacement Holder Nominee as set forth in
Section 1(d) or Section 1(e) and the Board, if required under Section 1(d) has approved such replacement Holder Nominee to fill the vacancy or (ii) 40 Business Days after the Stockholder receives notification of the
vacancy from the Company and the Stockholder has failed to designate a replacement Holder Nominee by such date. Notwithstanding the foregoing, the Stockholder shall have the right to remove any Director appointed by the Board or any committee
thereof pursuant to this paragraph. 
 (d) The Company shall (i) purchase directors’ and officers’ liability
insurance in an amount determined by the Board to be reasonable and customary and (ii) for so long as any Director to the Board nominated pursuant to the terms of the Agreement serves as a Director of the Company, maintain such coverage with
respect to such Director until a Holder Nominee Termination Event shall have occurred; provided that upon such Holder Nominee Termination Event the Company shall take all actions reasonably necessary to extend such directors’ and
officers’ liability insurance coverage for a period of not less than six years from any such event in respect of any act or omission occurring at or prior to such event. 
 (e) For so long as any Director nominated to the Board pursuant to the terms of this Agreement serves as a Director of the Company, the Company shall not amend, alter or repeal any right to
indemnification or exculpation covering or benefiting any Director nominated pursuant to this Agreement, including but not limited to Article 8 and 9 of the Certificate of Incorporation (whether such right is contained in the Certificate of
Incorporation or another document). 
 Section 3. Transfers; Termination. 

(a) The Stockholder’s rights hereunder do not attach to its shares of Common Stock and may only be assigned pursuant to
Section 5. If the Stockholder, together with its Affiliates, Beneficially Owns less than 15% of the Common Stock, the Stockholder shall cease to be a party to this Agreement and shall have no further rights or obligations hereunder;
provided that the Stockholder shall be obligated to comply with Section 1(c) and the Company shall be obligated to comply with Section 1(g) and Section 2(d). 

(b) Except pursuant to a Permitted Assignment under Section 5, this Agreement shall terminate automatically upon the
occurrence of a Holder Nominee Termination Event and shall be of no further force and effect, and no party thereto shall have any surviving

ADMINISTRATION 
 2.1 This Plan shall be administered by the Committee. The Committee shall, subject to the terms of this Plan, select eligible Persons (including key employees, directors, consultants and other service
providers (and prospective key employees, directors, consultants and other service providers)) for participation in this Plan and determine the amount, timing, and type of each Award to such Persons and the number of shares of Common Stock subject
to such an Award, any applicable Exercise Price, Restricted Period or vesting associated with the Award, the time and conditions of exercise of the Award, if applicable, and all other terms and conditions of the Award, including, without limitation,
the form of the Award Notice evidencing the Award. The Committee may, in its sole discretion and for any reason at any time take action such that any or all outstanding Awards shall become vested and/or exercisable in part or in full. The Committee
shall, subject to the terms of this Plan, interpret this Plan and the application thereof, correct any defects and supply any omissions under this Plan, establish rules and regulations it deems necessary or desirable for the administration of this
Plan and may impose, incidental to the grant of an Award, conditions with respect to the Award, such as limiting competitive employment or other activities and make any other determinations necessary or desirable for the administration of the Plan.
All such interpretations, rules, regulations and conditions shall be conclusive and binding on all parties. 
 2.2 No member of
the Board or Committee shall be liable for any act, omission, interpretation, construction or determination made in connection with this Plan in good faith, and the members of the Board and the Committee shall be entitled to indemnification and
reimbursement by the Company in respect of any claim, loss, damage or expense (including attorneys’ fees) arising therefrom to the full extent permitted by law (except as otherwise may be provided in the Company’s Certificate of
Incorporation and/or By-Laws) and under any directors’ and officers’ liability insurance that may be in effect from time to time. 
 ARTICLE III 
 SHARES SUBJECT TO THE PLAN 

3.1 Shares Available. An aggregate of 8,187,135 shares of Common Stock shall be available for Awards under this Plan, subject to
adjustment as provided below; provided, that, with respect to grants of Incentive Stock Options under the Plan, no more than 8, 187, 135 shares of Common Stock may be granted pursuant to Incentive Stock Options. Shares of Common Stock
used to pay the required Exercise Price or to satisfy any tax withholding obligation and shares underlying any Awards, or portion thereof, that are forfeited or cancelled, expire unexercised or are settled in cash are again available for Awards
under this Plan. Shares of Common Stock delivered by the Company in settlement of Awards may be authorized and unissued shares, shares held in the treasury of the Company, shares purchased on the open market or by private purchase, or a combination
of the foregoing. 

  
 5 

 3.2 Adjustments. In the event of any extraordinary dividend or other distribution
(other than an ordinary dividend) (whether in the form of cash, shares of Common Stock, other securities, or other property), recapitalization, reclassification, split, reverse split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets or shares of Common Stock of the Company, or exchange of shares of Common Stock or other securities of the
Company, issuance of warrants or other rights to purchase shares of Common Stock or other securities of the Company, or other similar transaction or event (including, without limitation, any unusual or nonrecurring events and/or a Change in
Control), and in the Committee’s opinion, such event affects the Common Stock such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to
be made available under the Plan or with respect to an Award, then the Committee shall, in such manner as it may deem equitable, make any adjustments, including, without limitation, any or all of the following: 

(a) adjusting any or all of (i) the number or kind of shares of Common Stock or other securities of the Company (or number and kind
of other securities or other property) that may be delivered in respect of Awards or with respect to which Awards may be granted under the Plan and (ii) the terms of any outstanding Award, including, without limitation, (A) the number or
kind of shares of Common Stock or other securities of the Company (or number and kind of other securities or other property) subject to outstanding Awards or to which outstanding Awards relate, (B) the exercise price with respect to any Award,
or (C) any performance conditions relating to the Award; and 
 (b) providing for a substitution or assumption of Awards,
accelerating the vesting, exercisability of, lapse of Restricted Period with respect to, or termination of, Awards or providing for a period of time for exercise prior to the occurrence of such event; provided, however, that in the
case of any “equity restructuring” (within the meaning of the Financial Accounting Standards Board Statement of Financial Accounting Standards No. 123 (revised 2004)), the Committee shall make an equitable or proportionate adjustment
to outstanding Awards to reflect such equity restructuring. Any adjustments under this Section shall be made in a manner that does not adversely affect the exemption provided pursuant to Rule 16b-3 under the Exchange Act, to the extent
applicable. The Company shall give each Grantee notice of an adjustment hereunder and, upon notice, such adjustment shall be conclusive and binding for all purposes. 
 Notwithstanding the foregoing, any such adjustments made to an Incentive Share Option shall be made in accordance with Section 424(a) of the Code and any adjustment to any other Award that is subject
to Section 409A of the Code shall be made in accordance with Section 409A of the Code, unless otherwise determined by the Committee in its sole discretion. 
 3.3 Termination. Upon the occurrence of any of the foregoing transactions and/or events set forth in Section 3.2 above, in which outstanding Awards do not remain otherwise outstanding and are
not assumed or substituted, the Committee may, in its sole discretion, cancel 

  
 6 

 
any one or more of such outstanding vested Awards and cause to be paid to the holders of such outstanding Awards as of the time of such transaction or event, in cash, shares of Common Stock,
other securities or other property, or any combination thereof, the value of such vested Awards, if any, as determined by the Committee (which if applicable may be based upon the price per share of Common Stock received or to be received by other
shareholders of the Company in such event), including without limitation, in the case of a vested outstanding Stock Option, a cash payment in an amount equal to the excess, if any, of the Fair Market Value (as of a date specified by the Committee)
of the shares of Common Stock covered by the Stock Option over the aggregate Exercise Price of such vested Stock Option (it being understood that, in such event, any Stock Option having an Exercise Price per share of Common Stock equal to, or in
excess of, the Fair Market Value per share of Common Stock covered by the Stock Option may be canceled and terminated without any payment or consideration therefor). The Committee may also provide in the terms of any Award Notice that upon the
occurrence of any of the foregoing transactions and/or events set forth in Section 3.2 above, in which outstanding Awards do not remain otherwise outstanding and are not assumed or substituted, then unless otherwise determined by the Committee
in connection with such transaction or event, any outstanding Awards that are unvested as of such transaction or event shall be forfeited as of such time. 
 3.4 Future Transactions. The existence of the Plan, the Award Notice and the Awards granted hereunder shall not affect or restrict in any way the right or power of the Company or the Board to make
or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issuance of shares of Common Stock or of options, warrants or
rights to purchase shares of Common Stock or of bonds, debentures, preferred or prior preference shares of Common Stock whose rights are superior to or affect the shares of Common Stock or the rights thereof or which are convertible into or
exchangeable for shares of Common Stock, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other act or proceeding, whether of a similar character or otherwise. 

3.5 The Committee’s determination in good faith under this Article III shall be final, binding and conclusive. 

ARTICLE IV

 ARTICLE V 
 STOCK OPTIONS 
 5.1 Grant of Stock Options. Stock Options shall be
subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of this Plan, as the Committee shall deem advisable, which may include, without limitation, noncompetition,
nonsolicitation, non-disclosure and/or other restrictive covenants as the Committee shall determine. 
 5.2 Exercise
Price. Except as otherwise provided by the Committee in the case of substitute awards issued in connection with a Change in Control or other event pursuant to Article IX or Article III of the Plan, the Exercise Price for each Award shall not be
less than 100% of the Fair Market Value per share of Common Stock as of the date of grant of such Award; provided, that, with respect to grants of Incentive Stock Options to Ten Percent Shareholders, the Exercise Price shall not be
less than 110% of the Fair Market Value per share of Common Stock as of the date of grant of such Award. 
 5.3 Vesting.
Unless otherwise determined by the Committee and specified in the applicable Award Notice, each Stock Option granted under this Plan shall vest and become exercisable with respect to twenty-five percent (25%) of the shares of Common Stock
covered by such Stock Option on each of the first four anniversaries of the date such Stock Option was granted; provided that the Grantee is employed by the Company or any Subsidiary on each such vesting date. Unless otherwise determined by the
Committee and specified in the applicable Award Notice, all Stock Options outstanding under the Plan shall vest and become exercisable with respect to one hundred percent (100%) of the shares of Common Stock covered by such Stock Option on the
occurrence of a Change in Control. 
 5.4 Option Period. All Stock Options granted under this Plan
shall expire seven (7) years following the applicable date of grant (the “Option Period”), subject to extension of the Option Period pursuant to Section 9.5 hereof or earlier termination as provided in Section 5.7
below or the Award Notice; provided, that if the Option Period would expire at a time when trading in the shares of Common Stock is prohibited by the Company’s insider trading policy (or Company-imposed “blackout period”), the
Option Period shall be automatically extended until the
30th day following the expiration of such prohibition (but
not beyond any date that would cause such Award to violate the provisions of Section 409A of the Code). Notwithstanding the foregoing, with respect to grants of Incentive Stock Options to Ten Percent Shareholders, the Option Period shall not
exceed five (5) years following the applicable date of grant. 
 5.5 Method of Exercise. Unless otherwise determined
by the Committee, and subject to Section 9.5 hereof, a Stock Option may be exercised by (x) giving written notice to the Company specifying the number of whole shares of Common Stock to be purchased, (y) accompanying such notice with
payment of the aggregate purchase price therefor in full in cash or by certified check and (z) executing such documents as the Company may reasonably request. In addition to the foregoing, in the discretion of the Committee payment of the
aggregate purchase price may be made (1) by delivery of shares of Common Stock (that are Mature Shares) having a Fair Market Value, determined as of the Exercise Date, equal to the 

  
 8 

 
aggregate purchase price payable by reason of such exercise, (2) authorizing the Company to withhold whole shares of Common Stock that would otherwise be delivered having an aggregate Fair
Market Value, determined as of the Exercise Date, equal to the amount necessary to satisfy such obligation, (3) in cash by a broker-dealer acceptable to the Company to whom the Grantee has submitted an irrevocable notice of exercise or
(4) a combination of (1), (2) and (3). Any fraction of a share of Common Stock that would be required to pay such purchase price shall be disregarded and the remaining amount due shall be paid in cash by the Grantee. 

5.6 Incentive/Non-Qualified Stock Options. Stock Options granted hereunder may be either Incentive Stock Options or Non-Qualified
Stock Options, as designated by the Committee in an Award Notice; provided, that awards of Incentive Stock Options shall be made only to employees of the Company and any “parent corporation” or a “subsidiary corporation” within
the meaning of Section 424 of the Code. 
 5.7 Termination of Employment. Unless otherwise provided in an Award
Notice or employment agreement between the Company and the affected Grantee, the following terms and conditions shall apply in the event of the termination of the Grantee’s employment. For the avoidance of doubt, references to
“employment” in this Article IV shall be to “service,” as applicable. 
 (a) Unvested Awards. In the
event that a Grantee’s employment is terminated for any reason, the Grantee shall forfeit the unvested portion of the Stock Option held by such Grantee as of the termination date. 

(b) For Cause. In the event that a Grantee’s employment is terminated by the Company or any Subsidiary for Cause, unless
otherwise provided in any written employment agreement between the Grantee and the Company or any Subsidiary, the Grantee shall forfeit any Stock Option held by such Grantee, whether or not vested, as of the termination date. 

(c) Death/Disability. In the event that a Grantee’s employment is terminated due to such Grantee’s death or by the
Company or any Subsidiary due to such Grantee’s Disability, any vested portion of a Stock Option held by such Grantee as of the termination date shall remain exercisable until the earlier of (i) one year following such termination date and
(ii) the date such Stock Option would otherwise expire by its terms. Thereafter, any unexercised portion of the Stock Option shall be forfeited immediately. 
 (d) Other than for Cause/Death/Disability. Except as provided otherwise in any Award Notice, in the event that a Grantee’s employment is terminated other than by reason of the Grantee’s
death and other than by the Company or any Subsidiary for Cause or due to the Grantee’s Disability, any vested portion of a Stock Option held by such Grantee as of the termination date shall remain exercisable until the earlier of
(i) ninety (90) days following such termination date and (ii) the date such Stock Option would otherwise expire by its terms. Thereafter, any unexercised portion of the Stock Option shall be forfeited immediately. 

(e) Voluntary Resignation. In the event that a Grantee’s employment is terminated by reason of the Grantee’s voluntary
resignation, any vested portion of a Stock Option held by such Grantee as of the termination date shall remain exercisable until the earlier 

  
 9 

 
of (i) thirty (30) days following such termination date and (ii) the date such Stock Option would otherwise expire by its terms. Thereafter, any unexercised portion of the Stock
Option shall be forfeited immediately. 
 ARTICLE VI 

STOCK APPRECIATION RIGHTS 
 6.1 Grant of Stock Appreciation Rights. The Committee may, in its discretion, either alone or in connection with the grant of another Award, grant a Stock Appreciation Right in accordance with the
Plan, the terms and conditions of which shall be set forth in an Award Notice. If granted in connection with a Stock Option, a Stock Appreciation Right shall cover the same number of shares of Common Stock covered by the Stock Option (or such lesser
number of shares as the Committee may determine) and shall, except as provided in this Article VI, be subject to the same terms and conditions as the related Stock Option. 
 6.2 Time of Grant. A Stock Appreciation Right may be granted (i) at any time if unrelated to a Stock Option, or (ii) if related to a Stock Option, at the time of grant of such Stock
Option. 
 6.3 Stock Appreciation Right Related to a Stock Option. 

(a) A Stock Appreciation Right granted in connection with a Stock Option shall be exercisable, subject to Section 9.5 hereof, at
such time or times and only to the extent that the related Stock Option is exercisable, and will not be transferable except to the extent the related Stock Option may be transferable. 

(b) Upon the exercise of a Stock Appreciation Right related to a Stock Option, the Grantee shall be entitled to receive an amount
determined by multiplying (i) the excess of the Fair Market Value of a share of Common Stock on the date of exercise of such Stock Appreciation Right over the per share exercise price under the related Stock Option, by (B) the number of
shares of Common Stock as to which such Stock Appreciation Right is being exercised. Notwithstanding the foregoing, the Committee may limit in any manner the amount payable with respect to any Stock Appreciation Right by including such a limit in
the Award Notice evidencing the Stock Appreciation Right at the time it is granted. 
 (c) Upon the exercise of a Stock
Appreciation Right granted in connection with a Stock Option, the Stock Option shall be canceled to the extent of the number of shares as to which the Stock Appreciation Right is exercised, and upon the exercise of a Stock Option granted in
connection with a Stock Appreciation Right, the Stock Appreciation Right shall be canceled to the extent of the number of shares of Common Stock as to which the Stock Option is exercised or surrendered. 

6.4 Stock Appreciation Right Unrelated to a Stock Option. The Committee may grant to a Grantee Stock Appreciation Rights unrelated
to Stock Options. A Stock Appreciation Right unrelated to Stock Options shall contain such terms and conditions as to exercisability, vesting and duration as the Committee shall determine. Upon exercise of a Stock Appreciation Right unrelated to a
Stock Option, the Grantee shall be entitled to receive an amount determined by 

  
 10 

 
multiplying (i) the excess of the Fair Market Value of a share of Common Stock on the date of exercise of such Stock Appreciation Right over the per share exercise price of the Stock
Appreciation Right, by (ii) the number of shares of Common Stock as to which the Stock Appreciation Right is being exercised. Notwithstanding the foregoing, the Committee may limit in any manner the amount payable with respect to any Stock
Appreciation Right by including such a limit in the Award Notice evidencing the Stock Appreciation Right at the time it is granted. 
 6.5 Method of Exercise. Except as provided in an Award Notice, Stock Appreciation Rights shall be exercised by a Grantee only by a written notice which has been approved by the Company and
delivered in person, by mail or such other approved manner to the Company at the Company’s principal executive office, specifying the number of shares of Common Stock with respect to which the Stock Appreciation Right is being exercised and
such other information as requested by the Company. If requested by the Committee, the Grantee shall deliver the Award Notice evidencing the Stock Appreciation Right being exercised and the Award Notice evidencing any related Stock Option to the
Company who shall endorse thereon a notation of such exercise and return such Award Notice to the Grantee. 
 6.6 Form of
Payment. Except as provided in an Award Notice, payment of the amount determined under this Article VI may be made in the discretion of the Committee solely in whole shares of Common Stock in a number determined at their Fair Market Value on the
date of exercise of the Stock Appreciation Right, or solely in cash, or in a combination of cash and shares. If the Committee decides to make full payment in shares of Common Stock and the amount payable results in a fractional share, payment for
the fractional share will be made in cash. 
 ARTICLE VII 

RESTRICTED AWARDS 
 7.1 Generally. Each grant of Restricted Stock and Restricted Stock Units shall be evidenced by an Award Notice. Each such grant shall be subject to the conditions set forth in this Article VII, and
to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Notice. 
 7.2 Share
Certificates; Escrow or Similar Arrangement. Upon the grant of Restricted Stock, the Committee may, but need not, cause a share certificate registered in the name of the Grantee to be issued and, if the Committee determines that the Restricted
Stock shall be held by the Company or in escrow rather than delivered to the Grantee pending the release of the applicable restrictions, the Committee may require the Grantee to additionally execute and deliver to the Company (i) an escrow
agreement satisfactory to the Committee, if applicable, and (ii) the appropriate share power (endorsed in blank) with respect to the Restricted Stock covered by such agreement. If a Grantee shall fail to execute an agreement evidencing an Award
of Restricted Stock and, if applicable, an escrow agreement and blank share power within the amount of time specified by the Committee, the Award shall be null and void. Subject to the restrictions set forth in this Article VII and the applicable
Award Notice, the Grantee generally shall have the rights and privileges of a shareholder as to such Restricted Stock, including 

  
 11 

 
without limitation the right to vote such Restricted Stock and to receive dividends; provided, however, that any dividends declared and paid during any period that such Restricted
Stock is subject to restrictions shall be accrued and paid to the Grantee when the applicable restrictions lapse. To the extent shares of Restricted Stock are forfeited, any share certificates issued to the Grantee evidencing such shares shall be
returned to the Company, and all rights of the Grantee to such shares and as a shareholder with respect thereto shall terminate without further obligation on the part of the Company. 

7.3 Vesting. Each Award Notice shall set forth the applicable Restricted Period and the terms pursuant to which such Restricted
Period shall lapse. 
 7.4 Delivery of Restricted Stock and Settlement of Restricted Stock Units. 

(a) Except as otherwise set forth in the applicable Award Notice, upon the expiration of the Restricted Period with respect to any
Restricted Stock, the restrictions set forth in the applicable Award Notice shall be of no further force or effect with respect to such shares except for those certain restrictions set forth in Section 9.6 hereof. If an escrow arrangement is
used, upon such expiration, the Company shall deliver to the Grantee, or his or her beneficiary, without charge, the share certificate evidencing the Restricted Stock that have not then been forfeited and with respect to which the Restricted Period
has expired (rounded down to the nearest full share). Dividends, if any, that may have been attributable to any particular shares of Restricted Stock shall be distributed to the Grantee in cash or, at the sole discretion of the Committee, in shares
of Common Stock having a Fair Market Value equal to the amount of such dividends within 30 days following the lapse of the Restricted Period, and, if such share is forfeited, the Grantee shall have no right to such dividends (except as otherwise set
forth in the applicable Award Notice). 
 (b) Unless otherwise provided in an Award Notice, upon the expiration of the
Restricted Period with respect to any outstanding Restricted Stock Units, the Company shall deliver, within 30 days thereafter, to the Grantee, or his or her beneficiary, without charge, one share of Common Stock for each such outstanding Restricted
Stock Unit; 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 in respect of such Restricted Stock Units.
If a cash payment is made in lieu of delivering shares of Common Stock, the amount of such payment shall be equal to the Fair Market Value of the shares of Common Stock as of the date on which the Restricted Period lapsed with respect to such
Restricted Stock Units, less an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld. 

  
 12 

 7.5 Legends on Restricted Stock. Each certificate representing Restricted Stock
awarded under the Plan shall bear a legend substantially in the form of the following in addition to any other information the Company deems appropriate until the lapse of the Restricted Period with respect to such shares of Common Stock:

 ARTICLE VIII 
 STOCK BONUS AWARDS 
 The Committee may issue unrestricted shares of Common
Stock, or other Awards denominated in shares of Common Stock, under the Plan to Grantees, either alone or in tandem with other Awards, in such amounts as the Committee shall from time to time in its sole discretion determine. Each Stock Bonus Award
granted under the Plan shall be evidenced by an Award Notice. Each Stock Bonus Award so granted shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award Notice. 

ARTICLE IX 

GENERAL 

9.1 Effective Date and Term of Plan. This Plan shall be effective as of the effective date of the Plan of Reorganization,
June 22, 2012 (the “Emergence Date”), and shall terminate as of the tenth anniversary of the Emergence Date, unless terminated earlier by the Board. Termination of this Plan shall not affect the terms or conditions of any Award
granted prior to termination. Confirmation of the Plan of Reorganization shall constitute all necessary approval by the stockholders of the Company of the Plan. 
 9.2 Amendments. The Board may amend this Plan and any Award Notice as it shall deem advisable, subject to any requirement of stockholder approval required by applicable law, rule or regulation;
provided, however, that no amendment may materially impair the rights of a Grantee without the consent of such Grantee. 
 9.3 Non-Transferability. Unless otherwise determined by the Committee, no Award shall be transferable other than by will, the laws of descent and distribution or pursuant to beneficiary designation
procedures approved by the Company. Unless otherwise specified by the Committee in an Award Notice, no Award may be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or
be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of any Award, such Award and all rights thereunder shall immediately become null and void.

  
 13 

 9.4 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 an Award made hereunder, payment by the holder of such Award 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 an Award, or 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) in cash from a broker-dealer acceptable to the Company to whom the Grantee has submitted an irrevocable
notice of exercise; (e) by delivering shares of Common Stock (that are Mature Shares) having an aggregate Fair Market Value, determined as of the date the obligation to withhold or pay, equal to the amount necessary to satisfy such obligation;
or (f) any combination of the foregoing. 
 9.5 Applicable Securities Laws and Restrictions on Exercise. Shares of
Common Stock issued pursuant to Awards granted under this Plan shall not be sold or transferred unless either they 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. In addition, in no event shall any Stock Option or Stock
Appreciation Right be exercised by a Grantee if such exercise would result in a violation of applicable securities and other laws, as determined by the Committee in its sole discretion. In the event that the exercise of any Stock Option or
settlement or vesting of any other Award is restricted pursuant to the foregoing, the Committee shall toll the applicable exercise period or otherwise delay such settlement or vesting until such restriction no longer exists. 

9.6 Restrictions on Shares. Each Award made hereunder shall be subject to the requirement that if at any time the Company
determines that the listing, registration or qualification of the shares of Common Stock subject to such Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is
necessary or desirable as a condition of, or in connection with, the delivery of shares thereunder, such shares shall not be delivered unless such listing, registration, qualification, consent, approval or other action shall have been effected or
obtained, free of any conditions not acceptable to the Company. The Company may require that certificates evidencing shares of Common Stock delivered pursuant to any Award made hereunder bear a legend similar to the following: 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED, QUALIFIED, APPROVED OR DISAPPROVED UNDER THE SECURITIES ACT OF
1933 OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR AN APPLICABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF SUCH ACT OR SUCH 

  
 14 

 
LAWS AND NEITHER THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION NOR ANY OTHER FEDERAL OR STATE REGULATORY AUTHORITY HAS PASSED ON OR ENDORSED THE MERITS OF THESE SECURITIES. 

9.7 No Right of Participation, Employment or Service. Unless otherwise set forth in an employment agreement, no Person shall have
any right to participate in this Plan. Neither this Plan nor any Award made hereunder shall confer upon any Person any right to continued employment by or service with the Company, any Subsidiary or any Affiliate of the Company or affect in any
manner the right of the Company, any Subsidiary or any Affiliate of the Company to terminate the employment of any Person at any time without liability hereunder. 
 9.8 Clawback/Forfeiture. To the extent required by applicable law (including without limitation Section 304 of the Sarbanes-Oxley Act and Section 954 of the Dodd-Frank Wall Street Reform
and Consumer Protection Act) and/or the rules and regulations of any securities exchange or inter-dealer quotation system on which the Common Stock is listed or quoted, Awards shall be subject (including on a retroactive basis) to clawback,

9.11 Other Agreements. Notwithstanding anything herein to the contrary, the Committee may require in any Award Notice, as a
condition to the grant of and/or the receipt of shares of Common Stock under an Award, that the Grantee execute the Investor Rights Agreement (prior to the occurrence of an Initial Public Offering), lock-up, shareholder or other agreements, as it
may determine in its sole and absolute discretion provided that such agreement is not materially inconsistent with the purpose of the Award. 
 9.12 International Participants. With respect to Grantees who are not subject to taxation in the United States, the Committee may in its sole discretion adopt a subplan with respect to such

 ARTICLE X 
 REPURCHASE RIGHTS 
 10.1 Repurchase Rights. 

(a) Except as otherwise required by law, unless otherwise specifically provided in any Award Notice, following a termination of any
Grantee’s service by the Company for Cause, the Company or its designee shall have the right to purchase any or all of a Grantee’s securities acquired upon vesting of Awards or exercise of Stock Options (the “Subject
Shares”), in either case, at a price per share of Common Stock as determined below (the “Repurchase Price”) at any time within 180 days following such termination of service. 

(b) Except as otherwise required by law, unless otherwise specifically provided in any Award Notice, the Repurchase Price per share shall
equal the lesser of (i) the per share exercise price paid in the case of Stock Options and the per share purchase price, if any, paid by the Grantee for shares of Common Stock acquired upon vesting of the Award (which amount shall be zero
($0.00) if no purchase price was paid therefor in connection with a “net cashless exercise”) and (ii) the Fair Market Value per share of Common Stock as of the date of termination of employment. 

(c) Payment of the purchase price in connection with any such purchase of the Subject Shares shall be in the form of cash. 

(d) The closing of the purchase and sale of the Subject Shares pursuant to this Section 10.1 shall be consummated as promptly as
practicable after notice of purchase is delivered by the Company to such Grantee. 
 (e) At any closing for the purchase of
Subject Shares, each Grantee selling Subject Shares shall deliver certificates representing such Subject Shares, duly endorsed with a signature guarantee for transfer and accompanied by all requisite transfer taxes, if any, and such Subject Shares
shall be free and clear of any liens, claims, options, charges, encumbrances or rights (other than those arising hereunder), and such selling Grantee shall so represent and warrant, and each shall further represent that it is the beneficial and
record owner of such Subject Shares and has the authority to sell such Subject Shares. At such closing, each purchaser of Subject Shares shall deliver at such closing payment for the Repurchase Price for each Subject Share purchased by it by
certified or official bank check or wire transfer. At such closing, all of the parties shall execute such additional documents as are otherwise reasonable, customary and appropriate in connection with such sale of Subject Shares. 

10.2 Initial Public Offering. The restrictions and rights set forth in this Article X shall expire upon the consummation of the
first public offering of the Company’s Common Stock pursuant to a registration statement (other than on a Form S-8 or successor forms) filed with, and declared effective by the Securities and Exchange Commission (the “Initial Public
Offering”).
