EXHIBIT A

PERFORMANCE STOCK UNIT AGREEMENT

This Performance Stock Unit Agreement (together with the Grant Notice to which this Agreement is attached, this “Agreement”) is made as of the Date of Grant set forth in the Grant Notice to which this Agreement is attached by and between IE PubCo Inc., a Delaware corporation (the “Company”), and                      (the “Participant”). Capitalized terms used but not specifically defined herein shall have the meanings specified in the Plan or the Grant Notice.

1.    Award. In consideration of the Participant’s past and/or continued service to the Company or its Affiliates and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, effective as of the Date of Grant set forth in the Grant Notice (the “Date of Grant”), the Company hereby grants to the Participant the Target PSUs set forth in the Grant Notice on the terms and conditions set forth in the Grant Notice, this Agreement and the Plan, which is incorporated herein by reference as a part of this Agreement. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control. To the extent earned and vested, (i) this Award represents the right to receive shares of Common Stock in an amount ranging from     % to     % of the Target PSUs and (ii) each Target PSU represents the right to receive a number of shares of Common Stock equal to     % of the total number of shares of Common Stock outstanding on each Performance Period End Date, subject to the terms and conditions set forth in the Grant Notice, this Agreement and the Plan. Unless and until any portion of this Award vests and becomes earned in the manner set forth in the Grant Notice, the Participant will have no right to receive any Common Stock or other payments in respect of this Award, except as otherwise specifically provided for in the Plan or this Agreement (including Section 4(b)). Prior to settlement of this Award, the Target PSUs and this Award represent an unsecured obligation of the Company, payable only from the general assets of the Company.

2.    Earning and Vesting of PSUs.

(a)    Except as otherwise set forth in Section 2(b), the Earned Amount for each Performance Period shall be determined with respect to a single Target PSU for such Performance Period based on the extent to which the Company has satisfied the Performance Goals set forth in the Grant Notice, which shall be determined by the Committee in its sole discretion following the end of such Performance Period as described in Exhibit B attached hereto. By way of example, (i) if the level of achievement with respect to the Absolute TSR Performance Goal is     % for a given Performance Period, then the Earned Amount with respect to the      Target PSU that is subject to the Absolute TSR Performance Goal is equal to     %, which means that     % (    % times     ) of the Target PSU shall have been earned; (ii) if the level of achievement with respect to the Relative TSR Performance Goal is equal to or greater than the      percentile for the same Performance Period, then the Earned Amount with respect to the      Target PSU that is subject to the Relative TSR Performance Goal is equal to     %, which means that     % (    % times     ) of the Target PSU shall have been earned; and (iii) the total Earned Amount with respect to the Target PSU for such Performance Period is determined to be     % (    % plus     %) of the Target PSU for such Performance Period, which is equivalent to a number of shares of Common Stock equal to     % of the total number of shares of Common Stock outstanding on the applicable

A-1

Performance Period End Date. To the extent that a Target PSU does not become earned during the corresponding Performance Period, such Target PSU shall be automatically forfeited without further notice and at no cost to the Company. In the event of the termination of that certain Management Agreement among the Company and the Participant, as amended from time to time (the “Management Agreement”) while any Target PSUs remain unearned (but after giving effect to any accelerated vesting pursuant to Section 2(b)), such unearned Target PSUs (and all rights arising from such Target PSUs and from being a holder thereof) will terminate automatically without any further action by the Company and will be forfeited without further notice and at no cost to the Company.

(b)    Upon the occurrence of a Change in Control or a complete liquidation or dissolution of the Company, the Earned Amount with respect to all unearned Target PSUs shall immediately be deemed to be     % of such Target PSUs on the Control Change Date or the date of liquidation or dissolution, as applicable, if the Management Agreement has not been terminated prior to such Control Change Date or such date of liquidation or dissolution, as applicable.

3.    Settlement of PSUs. As soon as administratively practicable following each Performance Period End Date, but in no event later than 30 days thereafter, the Company shall deliver to the Participant a number of shares of Common Stock equal to the Earned Amount with respect to the Target PSU for the Performance Period, provided, however, that, notwithstanding anything contained herein to the contrary, if insufficient shares of Common Stock remain available under the Plan to be delivered in settlement of the Earned Amount, the Company shall deliver to the Participant a cash amount equal to the product of the Fair Market Value on such Performance Period End Date and the number of shares of Common Stock that could not be delivered. All Common Stock issued hereunder shall be delivered either by delivering one or more certificates for such shares to the Participant or by entering such shares in book-entry form, as determined by the Committee in its sole discretion. The value of Common Stock shall not bear any interest owing to the passage of time. Neither this Section 3 nor any action taken pursuant to or in accordance with this Agreement shall be construed to create a trust or a funded or secured obligation of any kind.

4.    Rights as a Stockholder; Dividends.

(a)    The Participant shall have no rights as a stockholder of the Company with respect to any Common Stock that may become deliverable hereunder unless and until the Participant has become the holder of record of such Common Stock, and no adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of any such Common Stock, except as otherwise specifically provided for in the Plan or this Agreement; provided, however, that the Participant shall be entitled to participate in the gains and losses of the Company with respect to the Target PSUs granted hereunder.

(b)    The Participant will have no right to receive any dividends or other distribution with respect to a Target PSU unless and until shares of Common Stock have been delivered in respect of the Earned Amount determined with respect to such Target PSU, if any, in accordance with the terms and conditions of this Agreement.

A-2

5.    Tax Withholding. To the extent that the receipt, vesting or settlement of this Award results in any federal, state, local and/or foreign tax obligations applicable to the Participant, to the extent required under applicable law, the Participant shall make arrangements satisfactory to the Company for the satisfaction of such obligations.

6.    Non-Transferability. Except as otherwise determined by the Committee, the Award may not be transferred at any time prior to becoming earned, vested and settled.

7.    Compliance with Applicable Law. Notwithstanding any provision of this Agreement to the contrary, the issuance of Common Stock hereunder will be subject to compliance with all applicable requirements of applicable law with respect to such securities and with the requirements of any stock exchange or market system upon which the Common Stock may then be listed. No Common Stock will be issued hereunder if such issuance would constitute a violation of any applicable law or regulation or the requirements of any stock exchange or market system upon which the Common Stock may then be listed. In addition, Common Stock will not be issued hereunder unless (a) a registration statement under the Securities Act of 1933, as amended, is in effect at the time of such issuance with respect to the shares to be issued or (b) shares to be issued are permitted to be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act of 1933, as amended. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed to be necessary for the lawful issuance and sale of any Common Stock hereunder will relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority has not been obtained. As a condition to any issuance of Common Stock hereunder, the Company may require the Participant to satisfy any requirements that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect to such compliance as may be requested by the Company.

8.    Legends. If a stock certificate is issued with respect to Common Stock delivered hereunder, such certificate shall bear such legend or legends as the Committee deems appropriate in order to reflect the restrictions set forth in this Agreement and to ensure compliance with the terms and provisions of this Agreement, the rules, regulations and other requirements of the Securities and Exchange Commission, any applicable laws or the requirements of any stock exchange on which the Common Stock is then listed. If the shares of Common Stock issued hereunder are held in book-entry form, then such entry will reflect that the shares are subject to the restrictions set forth in this Agreement.

9.    Lock-Up Period. If so requested by the Company or any representative of the underwriters in connection with any offering of the Company’s securities (an “Offering”), the Participant (or other holder) shall not sell or otherwise transfer or distribute any Common Stock or other securities of the Company (or any securities convertible or exchangeable or exercisable for Common Stock or engage in any hedging transactions relating to Common Stock) during such period as may be requested in writing by such underwriters and agreed to in writing by the Company.

10.    Notices. Notices hereunder shall be mailed or delivered to the Company at its principal place of business and shall be mailed or delivered to the Participant at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish

A-3

to the other party in writing. Any notice that is delivered personally or by overnight courier or telecopier in the manner provided herein shall be deemed to have been duly given to the Participant when it is mailed by the Company or, if such notice is not mailed to the Participant, upon receipt by the Participant. Any notice that is addressed and mailed in the manner herein provided shall be conclusively presumed to have been given to the party to whom it is addressed at the close of business, local time of the recipient, on the fourth day after the day it is so placed in the mail.

11.    Consent to Electronic Delivery; Electronic Signature. In lieu of receiving documents in paper format, the Participant agrees, to the fullest extent permitted by law, to accept electronic delivery of any documents that the Company may be required to deliver (including, but not limited to, prospectuses, prospectus supplements, grant or award notifications and agreements, account statements, annual and quarterly reports and all other forms of communications) in connection with this and any other Award made or offered by the Company. Electronic delivery may be via a Company electronic mail system or by reference to a location on a Company intranet to which the Participant has access. The Participant hereby consents to any and all procedures the Company has established or may establish for an electronic signature system for delivery and acceptance of any such documents that the Company may be required to deliver, and agrees that the Participant’s electronic signature is the same as, and shall have the same force and effect as, the Participant’s manual signature.

12.    Agreement to Furnish Information. The Participant agrees to cause to be furnished to the Company all information requested by the Company to enable it to comply with any reporting or other requirement imposed upon the Company by or under any applicable statute or regulation.

13.    Entire Agreement; Amendment. This Agreement and the provisions of the Management Agreement that relate to this Award constitute the entire agreement of the parties with regard to the subject matter hereof, and contains all the covenants, promises, representations, warranties and agreements between the parties with respect to the Target PSUs granted hereby. Without limiting the scope of the preceding sentence, except as provided therein, all prior understandings and agreements, if any, among the parties hereto relating to the subject matter hereof are hereby null and void and of no further force and effect. The Committee may, in its sole discretion, amend this Agreement from time to time in any manner that is not inconsistent with the Plan; provided, however, that except as otherwise provided in the Plan or this Agreement, any such amendment that materially reduces the rights of the Participant shall be effective only if it is in writing and signed by both the Participant and an authorized officer of the Company.

14.    Severability and Waiver. If a court of competent jurisdiction determines that any provision of this Agreement is invalid or unenforceable, then the invalidity or unenforceability of such provision shall not affect the validity or enforceability of any other provision of this Agreement, and all other provisions shall remain in full force and effect. Waiver by any party of any breach of this Agreement or failure to exercise any right hereunder shall not be deemed to be a waiver of any other breach or right. The failure of any party to take action by reason of such breach or to exercise any such right shall not deprive the party of the right to take action at any time while or after such breach or condition giving rise to such rights continues.

A-4

15.    Clawback. Notwithstanding any provision in the Grant Notice, this Agreement or the Plan to the contrary, to the extent required by (a) applicable law, including, without limitation, the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, any Securities and Exchange Commission rule or any applicable securities exchange listing standards and/or (b) any policy that may be adopted or amended by the Board from time to time, all Common Stock issued hereunder shall be subject to forfeiture, repurchase, recoupment and/or cancellation to the extent necessary to comply with such law(s) and/or policy.

16.    Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED THEREIN, EXCLUSIVE OF THE CONFLICT OF LAWS PROVISIONS OF DELAWARE LAW.

17.    Successors and Assigns. The Company may assign any of its rights under this Agreement without the Participant’s consent. This Agreement will be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein and in the Plan, this Agreement will be binding upon the Participant and any Affiliate of the Participant to whom the Target PSUs may be transferred.

18.    Headings. Headings are for convenience only and are not deemed to be part of this Agreement.

19.    Section 409A. Notwithstanding anything herein or in the Plan to the contrary, this Award is intended to be exempt from the applicable requirements of Section 409A and shall be limited, construed and interpreted in accordance with such intent. Notwithstanding the foregoing, the Company and its Affiliates make no representations that this Award is exempt from or compliant with Section 409A and in no event shall the Company or any Affiliate be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by the Participant on account of non-compliance with Section 409A.
