1. Purposes of the Plan. The purposes of this 5to1 Holding Corp. 2011 Restricted Stock Unit Plan are to attract and retain the
best available personnel for positions of substantial responsibility, to provide additional incentives to Employees and Consultants of the Company and its Subsidiaries and to promote the success of the Company’s business. To accomplish the
foregoing, the Plan provides that the Company may grant Restricted Stock Units.

payment in connection with any Award under the Plan, as well as any Shares reacquired or withheld by the Company or one of its Subsidiaries to satisfy the tax withholding obligations related to any Award, shall not be available for subsequent Awards
under the Plan. Shares that are subject to or underlie Awards which expire or for any reason are cancelled or terminated, are forfeited, fail to vest, or for any other reason are not paid or delivered under the Plan shall again be available for
subsequent Awards under the Plan as if such Awards had never been granted. 
 4. Administration of the Plan. 

(a) Administrator. The Plan shall be administered by, and all Awards under the Plan shall be authorized by, the Administrator.
The “Administrator” means the Board or one or more Committees appointed by the Board or another Committee (within its delegated authority) to administer all or certain aspects of the Plan. Any such Committee shall be comprised solely of

delegate, to the extent permitted by Section 157(c) of the Delaware General Corporation Law and any other Applicable Law, to one or more Officers of the Company, its powers under this Plan (a) to designate the Employees other than an
Officer who is a Reporting Person who will receive grants of Awards under the Plan, and (b) to determine the number of Shares subject to, and the other terms and conditions of, such Awards. The Board may delegate different levels of authority
to different Committees with administrative and grant authority under the Plan. Except as otherwise provided in the bylaws of the Company or the applicable charter of any Administrator: (a) a majority of the members of the acting Administrator
shall constitute a quorum, and (b) the vote of a majority of the members present, assuming the presence of a quorum, or the unanimous written consent of the members of the Administrator shall constitute action by the acting Administrator.

 With respect to awards intended to satisfy the requirements for performance-based compensation under Section 162(m) of
the Code, the Plan shall be administered by a Committee consisting solely of two or more “outside directors” (within the meaning of Section 162(m) of 

  
 4 

 
the Code); provided, however, that the failure to satisfy such requirement shall not affect the validity of the action of any Committee otherwise duly authorized and acting in the
matter. Grants of and transactions in or involving Awards that are intended to be exempt under Rule 16b-3 must be duly and timely authorized by the Board or a Committee consisting solely of two or more non-employee directors (within the meaning
of Rule 16b-3). To the extent required by any applicable Stock Exchange, the Plan shall be administered by a Committee composed entirely of “independent” directors (within the meaning of the applicable Stock Exchange rules).

 (b) Powers of the Administrator. Subject to the provisions of the Plan and, in the case of a Committee, the specific
duties delegated by the Board to such Committee, and subject to the approval of any relevant authorities, including the approval, if required, of any Stock Exchange, the Administrator shall have the authority, in its discretion: 

(i) to determine the Fair Market Value of the Common Stock, in accordance with the definition of such term set forth
above; 
 (ii) to select the Consultants and Employees to whom Awards may from time to time be granted hereunder;

 (iii) to determine whether and to what extent Awards are granted hereunder; 

(iv) to determine the number of Shares of Common Stock, if any, to be covered by each Award granted hereunder; 

(v) to approve forms of agreements, not inconsistent with the terms of the Plan, for use under the Plan; 

(vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder,
including, but not limited to, the Share price, any restrictions or limitations, the vesting of any Award or the acceleration of vesting or waiver of forfeiture restrictions, and to determine the effect (which may include the suspension, delay or
extension of vesting dates) of a leave of absence, based in each case on such factors as the Administrator shall determine in its sole discretion; 
 (vii) to determine whether and under what circumstances an Award may be settled in cash or other consideration (other than Shares of Common Stock); 

(viii) to adjust the number of Shares subject to any Award, adjust the price of any or all outstanding Awards or otherwise
change previously imposed terms and conditions with respect to any Award, in each case, in such circumstances as the Administrator may deem appropriate and subject to Sections 3 and 13 hereof; 

(ix) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; and 

(x) in order to fulfill the purposes of the Plan and without amending the Plan, to modify Awards to Participants who are
foreign nationals or employed outside of the United States in order to recognize differences in applicable local law, tax policies or customs. 

  
 5 

 (c) Effect of Administrator’s Decision. All decisions, determinations and
interpretations of the Administrator shall be final and binding on all holders of any Award. 
 5. Eligibility.

 (a) Recipients of Grants. Awards may be granted to eligible Employees and Consultants. An Employee or Consultant who
has been granted an Award under the Plan may, if he or she is otherwise eligible, be granted additional Awards. 
 (b) No
Employment Rights. The Plan shall not confer upon any Participant any right with respect to the continuation of such Participant’s employment or consulting relationship with the Company, nor shall it interfere in any way with such
Participant’s right or the Company’s right to terminate his or her employment or consulting relationship at any time, with or without Cause. 
 6. Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company as described in Section 17 of
the Plan. It shall continue in effect until May 26, 2021, unless sooner terminated pursuant to Section 13 of the Plan. 
 7. Term of Awards. The term of each Award shall be stated in the written agreement between the Company and Participant evidencing such Award; provided, however, that the term of
any Award shall be no more than seven (7) years from the date of grant thereof or such shorter term as may be provided in such agreement. 
 8. Restricted Stock Units. 
 (a) General. Restricted Stock Units
may be issued either alone or in addition to other Awards granted under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will grant Restricted Stock Units under the Plan, it shall advise the
Participant in writing of the terms, conditions and restrictions related to the offer (which may include restrictions based on performance criteria, passage of time or other factors or a combination thereof), and the number of Restricted Stock Units
that such person shall be entitled to receive. The offer shall be accepted by execution of an Award Agreement in the form determined by the Administrator. 
 (b) Rights as a Stockholder. A Participant who is awarded Restricted Stock Units shall possess no incidents of Common Stock ownership with respect to the Shares represented by such Restricted
Stock Units; provided, that the Award Agreement may provide for dividend equivalents on the Award. 
 (c) Termination
of Employment. Except as otherwise expressly provided in the Award Agreement, in the event of the termination of the Participant’s employment or service with the Company, Parent or any Subsidiary for any reason prior to the lapsing of the
restrictions with respect to any Restricted Stock Units, such Restricted Stock Units held by the Participant shall be automatically forfeited by the Participant as of the date of termination. Neither the Participant nor any of the Participant’s
successors, heirs, assigns or personal representatives shall have any rights or interests in any Restricted Stock Units that are so forfeited. 

  
 6 

 (d) Other Provisions. The Award Agreement shall contain such other terms,
provisions and conditions as the Administrator may determine in its sole discretion, consistent with the Plan. In addition, the provisions of the Restricted Stock Units Award Agreements need not be the same with respect to each Participant who is
awarded Restricted Stock Units. 
 9. Tax Withholding. Upon any exercise. vesting or payment of an Award, or upon
any other tax withholding event or right in connection with the Award, the Company or one of its Subsidiaries shall have the right, at its option, to: 
 (a) require the Participant (or the Participant’s personal representative or beneficiary, as the case may be) to pay or provide for payment of the minimum amount of any taxes which the Company or one
of its Subsidiaries may be required to withhold with respect to such Award event or payment; or 
 (b) deduct from any amount
otherwise payable in cash to the Participant (or the Participant’s personal representative or beneficiary, as the case may be) the minimum amount of any taxes which the Company or one of its Subsidiaries may be required to withhold with respect
to such Award event or payment. 
 In the event that any tax is required to be withheld in connection with the delivery of
Shares under the Plan, the Administrator may in its sole discretion (subject to any Applicable Laws) (i) require or grant (either at the time of the Award or thereafter) to the Participant the right to elect, pursuant to such rules and subject
to such conditions as the Administrator may establish, that the Company reduce the number of Shares to be delivered by (or otherwise reacquire from the Participant) the appropriate number of Shares, valued in a consistent manner at their Fair Market
Value or at their sales price in accordance with authorized procedures for cashless exercises, as necessary to satisfy the minimum applicable withholding obligation on exercise, vesting or payment, or (ii) permit the Participant
to surrender to the Company Shares which (A) in the case of Shares initially acquired from the Company, have been owned by the Participant for such period (if any) as may be required to avoid a charge to the Company’s earnings, and
(B) have a Fair Market Value equal to the minimum amount required to be withheld, or (iii) have the Company withhold from proceeds of the sale of such Shares (either through a voluntary sale or through a mandatory sale arranged by the
Company on the Participant’s behalf) the minimum amount required to be withheld. For these purposes, the Fair Market Value of the Shares to be withheld or repurchased, as applicable, shall be determined on the date that the amount of tax to be
withheld is to be determined pursuant to the Code (the “Tax Date”). 
 Any surrender by a Reporting Person of
previously-owned Shares in order to satisfy tax withholding obligations incurred in connection with an Award granted under the Plan must comply with the applicable provisions of Rule 16b-3. 

  
 7 

 All elections by a Participant to have Shares withheld to satisfy tax withholding
obligations shall be made in a form acceptable to the Administrator and shall be subject to the following restrictions: (i) the election must be made on or prior to the applicable Tax Date; (ii) once made, the election shall be irrevocable
as to the particular Shares for which the election is made; and (iii) all elections shall be subject to the approval or disapproval of the Administrator. 
 10. Adjustments Upon Changes in Capitalization, Corporate Transactions. 

(a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, (i) the number and type
of shares of Common Stock (or other securities) covered by each outstanding Award, (ii) the number and type of shares of Common Stock (or other securities) that have been authorized for issuance under the Plan but as to which no Awards have yet
been granted or that have been returned to the Plan upon cancellation or expiration of an Award or otherwise, (iii) the maximum number of shares of Common Stock for which Awards may be granted to any Employee under the Plan, (iv) the price
per share of Common Stock covered by each such outstanding Award, and/or (v) the securities, cash or other property deliverable upon exercise or payment of any outstanding Awards, in each case to the extent necessary to preserve (but not
increase) the level of incentives intended by the Plan and the then-outstanding Awards, shall be equitably and proportionately adjusted for any dividend of stock or other property (other than cash) by the Company, any increase or decrease in the
number of issued Shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination, recapitalization or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of
Common Stock effected without receipt of consideration by the Company; provided, however, that the conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of
consideration.” Such adjustment(s) shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or of
securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares of Common Stock (or other securities) subject to an Award. 

It is intended that, if possible, any adjustments contemplated by the preceding paragraph be made in a manner that satisfies applicable
legal, tax and accounting (so as not to trigger any charge to earnings with respect to such adjustment) requirements (including, without limitation, Section 409A of the Code and Section 162(m) of the Code). Without limiting the generality
of Section 4(c) hereof, any good faith determination by the Board as to whether an adjustment is required in the circumstances pursuant to this Section 10(a), and the extent and nature of any such adjustment, shall be final, conclusive and
binding on all persons. 
 (b) Corporate Transactions. In the event of the proposed dissolution or liquidation of
the Company, each Award granted hereunder will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Administrator. Additionally, the Administrator may, in the exercise of its sole discretion in
such instances, declare that any Award shall terminate as of a date fixed by the Administrator and that each Award shall be vested and non-forfeitable and any conditions on each such Award shall lapse, as to all or any part of such Award, including
Shares as to which the Award would not otherwise be exercisable or non-forfeitable. In the event of a proposed sale of all or substantially all of the 

  
 8 

 
assets of the Company, or the merger of the Company with or into another corporation, each Award shall be assumed or an equivalent Award shall be substituted by such successor corporation or a
parent or subsidiary of such successor corporation, unless the Administrator determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that the Award shall be vested and non-forfeitable and any conditions on
each such Award shall lapse, as to all or any part of such Award, including Shares as to which the Award would not otherwise be exercisable or non-forfeitable. If the Administrator makes an Award exercisable or non-forfeitable in lieu of assumption
or substitution in the event of a merger or sale of assets, the Administrator shall notify the Participant that such Award shall be exercisable for a period of thirty (30) days from the date of such notice, and thereafter will terminate upon
the expiration of such period. 
 11. Non-Transferability of Awards. An Award may not be sold, pledged, assigned,
hypothecated, transferred, or otherwise disposed of in any manner other than by will or by the laws of descent or distribution; provided, however, that the Administrator may, in its discretion, grant Awards that are, or provide that
one or more outstanding Awards are, transferable to a “family member” (as that term is defined in the United States Securities and Exchange Commission General Instructions to Form S-8 Registration Statement under the Securities Act of
1933, as amended) of the Participant through a gift or domestic relations order. Any permitted transfer shall be subject to compliance with the Applicable Laws. Except as otherwise provided by the Administrator, during the lifetime of the
Participant, an Award may only be exercised or Shares may only be acquired pursuant to an Award by the Participant or a transferee of an Award as permitted by this Section 11. 

12. Time of Granting of an Award. The date of grant of an Award shall, for all purposes, be the date on which the
Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator in compliance with applicable legal, tax and accounting requirements (including, without limitation, Section 409A of the
Code). Notice of the determination shall be given to each Employee or Consultant, as applicable, to whom an Award is so granted within a reasonable time after the date of such grant. 

13. Amendment and Termination of the Plan. 
 (a) Amendment and Termination. Subject to 13(c) below, the Administrator may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof at any time, provided, that
no such amendment, alteration, suspension, discontinuation or termination shall be made without stockholder approval if (i) such approval is necessary to comply with any tax, securities or regulatory laws or requirements, any other Applicable
Laws, or any applicable Stock Exchange requirements with which the Administrator intends the Plan to comply or (ii) such amendment constitutes a “material amendment.” For purposes of the Plan, a “material amendment” shall
mean an amendment that (a) materially increases the benefits accruing to Participants under the Plan, (b) materially increases the number of securities that may be issued under the Plan, (c) materially modifies the requirements for
participation in the Plan, or (d) is otherwise deemed a material amendment by the Administrator pursuant to any Applicable Laws or applicable accounting or Stock Exchange rules. 

  
 9 

 (b) Amendments to Awards. Without limiting any other express authority of the
Administrator under (but subject to the express limits of) the Plan, the Administrator may, by agreement, resolution or written policy, waive conditions of or limitations on Awards that the Administrator has previously imposed in its sole discretion
without the consent of the Participant, and (subject to the requirements of Section 4(b) and Section 13(c)) may make other changes to the terms and conditions of Awards. 

(c) Limitations on Amendments to Plan and Awards. No amendment, suspension or termination of the Plan or change of or affecting
any outstanding Award shall, without written consent of the Participant, affect in any manner materially adverse to such Participant any rights or benefits of such Participant or obligations of the Company under any Award granted under the Plan
prior to the effective date of such change. Changes, settlements and other actions contemplated by Section 10 hereof shall not be deemed to constitute changes or amendments for purposes of this Section 13(c). 

14. Compliance with Laws. The Plan, the granting and vesting of Awards under the Plan, the offer, issuance and delivery of
Shares of Common Stock, and/or the payment of money under the Plan or under Awards are subject to compliance with all applicable federal, state and foreign laws, rules and regulations (including but not limited to state and federal securities laws
and federal margin requirements) and to such approvals by any listing, regulatory or governmental authority as may, in the opinion of counsel for the Company, be necessary or advisable in connection therewith. Any person acquiring securities under
the Plan will, if requested by the Company or one of its Subsidiaries, provide such assurances and representations to the Company or one of its Subsidiaries as the Administrator may deem necessary or desirable to assure compliance with all
applicable legal and accounting rules or requirements. 
 15. Reservation of Shares. During the term of this Plan
(as set forth in Section 6 hereof) , the Company will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority has not been obtained. 
 16. Award Agreements. Each Award
granted under the Plan shall be evidenced by either (i) a written Award agreement in a form approved and executed by the Company by an officer duly authorized to act on its behalf, or (2) an electronic notice of Award grant in a form
approved and recorded by the Company (or its designee) in an electronic recordkeeping system used for the purpose of tracking award grants under the Plan generally (in each case, an “Award Agreement”), as the Company may provide
and, in each case and if required by the Administrator, executed or otherwise electronically accepted by the Participant in such form and manner as the Administrator may require. The Administrator may authorize any Officer of the Company (other than
the particular Participant) to execute any or all Award Agreements on behalf of the Company. The Award Agreement shall set forth the material terms and conditions of the award as established by the Administrator consistent with the express
limitations of the Plan. 

  
 10 

 17. Stockholder Approval. Continuance of the Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months before or after the date of the Board’s adoption of the Plan. Such stockholder approval shall be obtained in the manner and to the degree required under applicable federal and state law
and the rules of any Stock Exchange upon which the Shares are listed. 
 18. Unfunded Status of Plan. The Plan is
intended to constitute an “unfunded” plan for incentive compensation. With respect to any payments not yet made to a participant by the Company, nothing contained herein shall give any participant any rights that are greater than those of
a general creditor of the Company. 
 19. Governing Law. The Plan and all determinations made and actions taken pursuant
hereto shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the conflict of laws principles thereof.

the date any Restricted Stock Units subject to the Award shall vest and become non-forfeitable (and in no event later than March 15 of the year following the year in which such vesting occurs) (the “Payment Date”), such
Restricted Stock Units shall be paid by the Company delivering to the Grantee a number of shares of Common Stock (“Shares”) equal to the number of Restricted Stock Units that become vested and non-forfeitable upon that Payment Date
(rounded down to the nearest whole share). The Company shall issue the Shares either (i) in certificate form or (ii) in book entry form, registered in the name of the Grantee. Delivery of any certificates will be made to the Grantee’s
last address reflected on the books of the Company and its Subsidiaries unless the Company is otherwise instructed in writing. The Grantee shall not be required to pay any cash consideration for the Restricted Stock Units or for any Shares received
pursuant to the Award. Neither the Grantee nor any of the Grantee’s successors, heirs, assigns or personal representatives shall have any further rights or interests in any Restricted Stock Units that are so paid. Notwithstanding the foregoing,
the Company shall have no obligation to issue Shares in payment of the Restricted Stock Units unless such issuance and such payment shall comply with all relevant provisions of law and the requirements of any Stock Exchange. 

(e) Termination of Employment. In the event of the termination of the Grantee’s employment or service with the Company,
Parent or any Subsidiary for any reason prior to the lapsing of the restrictions in accordance with Section 2(c) hereof with respect to any of the Restricted Stock Units granted hereunder, such portion of the Restricted Stock Units held by the
Grantee shall be automatically forfeited by the Grantee as of the date of termination. Neither the Grantee nor any of the Grantee’s successors, heirs, assigns or personal representatives shall have any rights or interests in any Restricted
Stock Units that are so forfeited.

 (f) Corporate Transactions. The following provisions shall apply to the corporate
transactions described below: 
 (i) In the event of a proposed dissolution or liquidation of the Company, the Award will
terminate and be forfeited immediately prior to the consummation of such proposed transaction, unless otherwise provided by the Administrator. 
 (ii) In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, the Award shall be assumed or substituted with
an equivalent award by such successor corporation, parent or subsidiary of such successor corporation; provided that the Administrator may determine, in the exercise of its sole discretion in connection with a transaction that constitutes a
permissible distribution event under Section 409A(a)(2)(A)(v) of the Code, that in lieu of such assumption or substitution, the Award shall be vested and non-forfeitable and any conditions or restrictions on the Award shall lapse, as to all or
any part of the Award, including Restricted Stock Units as to which the Award would not otherwise be non-forfeitable. 
 (g)
Income Taxes. Except as provided in the next sentence, the Company shall withhold and/or reacquire a number of Shares issued in payment of (or otherwise issuable in payment of, as the case may be) the Restricted Stock Units having a Fair
Market Value equal to the taxes that the Company determines it or the Employer is required to withhold under applicable federal, state and local tax laws with respect to the Restricted Stock Units (with such withholding obligation determined based
on any applicable minimum statutory withholding rates). In the event the Company cannot (under applicable legal, regulatory, listing or other requirements, or otherwise) satisfy such tax withholding obligation in such method or in the event that the
Restricted Stock Units are paid in cash (as opposed to Shares), the Company may satisfy such withholding by any one or a combination of the following methods: (i) by requiring the Grantee to pay such amount in cash or check; (ii) by
reducing the amount of any cash otherwise payable to the Grantee with respect to the Restricted Stock Units; (iii) by deducting such amount out of any other compensation otherwise payable to the Grantee; and/or (iv) by allowing the Grantee
to surrender shares of Common Stock of the Company which (a) in the case of shares initially acquired from the Company (upon exercise of a stock option or otherwise), have been owned by the Grantee for such period (if any) as may be required to
avoid a charge to the Company’s earnings, and (b) have a Fair Market Value on the date of surrender equal to the amount required to be withheld;. For these purposes, the Fair Market Value of the Shares to be withheld or repurchased, as
applicable, shall be determined on the date that the amount of tax to be withheld is to be determined. 
 Section 3.
Miscellaneous 
 (a) Notices. Any and all notices, designations, consents, offers, acceptances and any other

Officer and the General Counsel of the Company at the principal office of the Company and, (ii) in the case of the Grantee, to the Grantee’s address appearing on the books of the Company or to the Grantee’s residence or to such other

confer upon the Grantee any right to continue in the employ of the Company, a Parent or any Subsidiary or shall interfere with or restrict in any way the right of the Company, Parent or any Subsidiary, which is hereby expressly reserved, to remove,
terminate or discharge the Grantee at any time for any reason whatsoever, with or without Cause and with or without advance notice.

the right to impose other requirements on the Grantee’s participation in the Plan, to the extent the Company determines it is necessary or advisable in order to comply with local law or facilitate the administration of the Plan, and to require
the Grantee to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing. 
 (e)
Successors. The terms of this Agreement shall be binding upon and inure to the benefit of the Company, its successors and assigns, and of the Grantee and the beneficiaries, executors, administrators, heirs and successors of the Grantee.

respect to the subject matter contained herein and therein and supersede all prior communications, representations and negotiations in respect thereto.

conflict of laws principles thereof. 
 (j) Headings. The headings of the Sections hereof are provided for convenience
only and are not to serve as a basis for interpretation or construction, and shall not constitute a part, of this Agreement.
