	Section 6.6.	– Amendment 

 This
Grant may be amended only by a writing executed by the Company and the Grantee which specifically states that it is amending this Grant. 
  

	Section 6.7.	– Governing Law 

 The

conducted expeditiously in accordance with the American 

  
 4 

 
Arbitration Association rules, by a single independent arbitrator. Such arbitration process shall take place within the Borough of Manhattan, in the City of New York, New York. The decision of
the arbitrator shall be final and binding upon all parties hereto and shall be rendered pursuant to a written decision, which contains a detailed recital of the arbitrator’s reasoning. Judgment upon the award rendered may be entered in any
court having jurisdiction thereof. Each party shall bear its own legal fees and expenses. Notwithstanding anything herein to the contrary, if any other agreement between the Grantee and the Company or its subsidiaries concerning the provision of
services by the Grantee to the Company contains a similar provision relating to arbitration and/or dispute resolution, such provision in such agreement shall govern any controversy hereunder. 

 

	Section 6.9.	– Code Section 409A 

Notwithstanding any other provisions of this Agreement or the Plan, the Deferred Stock Units granted hereunder shall not be deferred,
accelerated, extended, paid out or modified in a manner that would result in the imposition of an additional tax under Section 409A of the Code upon the Grantee. In the event it is reasonably determined by the Committee that, as a result of
Section 409A of the Code, the transfer of Shares under this Agreement may not be made at the time contemplated hereunder without causing the Grantee to be subject to taxation under Section 409A of the Code, the Company will make such
payment on the first day that would not result in the Grantee incurring any tax liability under Section 409A of the Code. Notwithstanding anything herein to the contrary, if at the time of the Grantee’s termination of service with the
Company the Grantee is a “specified employee” as defined in Section 409A of the Internal Revenue Code of 1986, as amended and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such
termination of service is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any
reduction in such payments or benefits ultimately paid or provided to the Grantee) until the date that is six months following the Grantee’s termination of service with the Company (or the earliest date as is permitted under Section 409A
of the Code without any accelerated or additional tax).

fair dealing and good faith. 
 Section 4.3 No Conflict. The execution, delivery and performance of this Agreement
and the Stockholders Agreement by the Investor and the consummation by the Investor of the transactions contemplated hereby and thereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or
constitute a default under, any material agreement to which the Investor is a party or by which the Investor is bound or to which any of the property or assets of the Investor is subject, (b) conflict with or result in any violation of the
provisions of the organizational documents of the Investor, or (c) violate any statute, order, rule or regulation of any court or governmental agency or body having jurisdiction over the Investor or the property or assets of the Investor,

the one hand, and the Company or any of its

such parties. 
 Section 4.5 Investment. The Investor is an “accredited investor” (as defined in Rule 501
promulgated under the Securities Act) and is knowledgeable and experienced in finance, securities and investments and has had sufficient experience analyzing and investing in securities similar to the Shares so as to be capable of evaluating the
merits and risks of an investment in the Shares. The Shares are being acquired for the Investor’s own account or the account of its Affiliates, not as a nominee or agent, and with no present intention of distributing the Shares or any part
thereof, and the Investor has no present intention of selling or granting any participation in or otherwise distributing the same in any transaction in violation of the securities laws of the United States or any state, without prejudice, however,

exemption from registration thereunder, in each case in accordance with all applicable securities laws of the states or other jurisdictions, and in the case of a transaction exempt from registration, such securities may only be transferred if the
transfer agent for such securities has received documentation satisfactory to it that such transaction does not require registration under the Securities Act.”

The Company agrees to indemnify the Investor and its Representatives (collectively, “Investor Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations,

incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Company contained herein, provided that such claim for
indemnification relating to a breach of the representations or warranties is made prior to the expiration of such representations or warranties; and provided, further, that to the extent that the Losses incurred by the Investor Related Parties as a
result of a breach by the Company of the representations and warranties contained herein are the result of Losses incurred by the Company, the maximum aggregate amount for which the Company may be liable for indemnification of the Investor Related
Parties relating to such breach shall be limited to the amount of such Losses incurred by the Company, but excluding any amounts paid to the Investor pursuant to the provisions of this Article VI, multiplied by the Investor’s
Percentage Ownership. 
 Section 6.2 Indemnification by the Investor. The Investor agrees to indemnify the Company
and its Representatives (collectively, “Company Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of
action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and
disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising
out of, or in any way related to the breach of any of the representations, warranties or covenants of the Investor contained herein, provided that such claim for indemnification relating to a breach of the representations and warranties is made
prior to the expiration of such representations and warranties. 
 Section 6.3 Indemnification Procedure. Promptly
after any Company Related Party or Investor Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third Person,
which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement
of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is
materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be
reasonably 

  
 25 

 
acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it
shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof.
Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control.
Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long
as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability;
provided, however, that the Indemnified Party shall be entitled (a) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (b) if (i) the Indemnifying
Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (ii) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified
Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be
deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the
expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any
indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance
by, the Indemnified Party.

Company of the occurrence of such event or otherwise becoming aware that it beneficially owns (as determined in accordance with Rule 13d-3 under the Exchange Act, but excluding for this purpose any attribution of ownership of securities held by
persons who are not affiliates of CPPIB) less than 5.0% of the outstanding shares of Common Stock, within which to buy (in accordance with applicable laws) additional shares of Common Stock in the market in order to increase the number of shares of
Common Stock it beneficially owns (as determined in accordance with Rule 13d-3 under the Exchange Act, but excluding for this purpose any attribution of ownership of securities held by persons who are not affiliates of CPPIB) to at least 5.0% of the
outstanding shares of Common Stock. 
 (b) If, at any time, the Holders beneficially own (as determined in accordance with Rule
13d-3 under the Exchange Act, but excluding for this purpose any attribution of ownership of securities held by persons who are not affiliates of CPPIB), in the aggregate, at least 20.0% of the outstanding shares of Common Stock, the Company will
cause one additional person designated in writing by CPPIB (the “Additional CPPIB Board Representative” and, together with the CPPIB Board Representative, the “CPPIB Board Representatives”) to be elected or

  
 3 

 
appointed to the Board subject to the satisfaction of all legal and governance requirements regarding service as a Director and to the reasonable approval of the Board or the Nominating and
Governance Committee; provided, however, that CPPIB shall only have the right to appoint the Additional CPPIB Representative if the Board consists of 10 or more persons (after giving effect to the addition of the Additional CPPIB Board
Representative). After such appointment, so long as the Holders beneficially own (as determined in accordance with Rule 13d-3 under the Exchange Act, but excluding for this purpose any attribution of ownership of securities held by persons who are
not affiliates of CPPIB), in the aggregate, at least 20.0% of the outstanding shares of Common Stock, the Company will be required to recommend to its stockholders the election of the Additional CPPIB Board Representative at the Company’s
annual meeting, subject to the satisfaction of all legal and governance requirements regarding service as a Director and to the reasonable approval of the Nominating and Governance Committee of the Board (such approval not to be unreasonably
withheld or delayed), to the Board. If the Holders no longer beneficially own (as determined in accordance with Rule 13d-3 under the Exchange Act, but excluding for this purpose any attribution of ownership of securities held by persons who are not
affiliates of CPPIB), in the aggregate, at least 20.0% of Common Stock, CPPIB will have no further rights under this Section 2(b), and, at the written request of the Board, shall use all reasonable best efforts to cause the Additional CPPIB
Board Representative to resign from the Board as promptly as possible thereafter; provided, however, that upon the occurrence of any event which results in the Holders beneficially owning less than 20.0% of the outstanding shares of Common Stock,
other than the sale of shares of Common Stock by the Holders, the Holders shall have 45 days after being advised in writing by the Company of the occurrence of such event or otherwise becoming aware that it beneficially owns (as determined in
accordance with Rule 13d-3 under the Exchange Act, but excluding for this purpose any attribution of ownership of securities held by persons who are not affiliates of CPPIB) less than 20.0% of the outstanding shares of Common Stock, within which to
buy (in accordance with applicable laws) additional shares of Common Stock in the market in order to increase the number of shares of Common Stock it beneficially owns (as determined in accordance with Rule 13d-3 under the Exchange Act, but
excluding for this purpose any attribution of ownership of securities held by persons who are not affiliates of CPPIB) to at least 20.0% of the outstanding shares of Common Stock. 

(c) The CPPIB Board Representatives (including any successor nominees) duly selected in accordance with Sections 2(a) and 2(b), shall,
subject to applicable law, be the Company’s and the Nominating and Governance Committee’s nominees to serve on the Board. The Company shall take all Necessary Actions to cause the CPPIB Board Representatives to be elected as Directors of
the Company. 
 (d) CPPIB shall have the power to designate the CPPIB Board Representatives’ replacements upon the death,
resignation, retirement, disqualification or removal from office of such Directors. Such replacement CPPIB Board Representative shall be subject to the satisfaction of all legal and governance requirements regarding service as a Director and to the
reasonable approval of the Nominating and Governance Committee of the Board (such approval not to be unreasonably withheld or delayed). The Board shall take all Necessary Actions to cause the Company to fill the vacancy resulting therefrom with such
person (including such person, subject to applicable law, being the Company’s and the Nominating and Governance Committee’s nominee to serve on the Board, using all reasonable best efforts to have such person elected as a Director and the
Company soliciting proxies for such person to the same extent as it does for any of its other nominees to the Board). 

  
 4 

 (e) The CPPIB Board Representatives shall be entitled to the same rights, and shall be bound
by the same duties and obligations as other non-management members of the Board generally. 
 (f) So long as the Holders
beneficially own (as determined in accordance with Rule 13d-3 under the Exchange Act, but excluding for this purpose any attribution of ownership of securities held by persons who are not affiliates of CPPIB), in the aggregate, greater than 5.0% of
the outstanding shares of Common Stock of the Company, the Holders shall have the pre-emptive right to purchase their pro rata portion of any Equity Securities (other than Excluded Securities) (the “New Securities”) that the Company may,
from time to time, propose to issue or sell to any party, whether by way of a public offering or private placement (each, an “Offering”). In order for the Holders to assess such an Offering, the Company shall provide written notice to the
Holders when the Company considers a possible Offering in which the Investor would have the right to participate pursuant to this Section 2(f), which notice shall reflect the type of Offering proposed (e.g. marketed deal or private placement).
The Company shall provide the Holders with at least four (4) Business Days prior notice of the Company announcing that it is conducting an Offering and the Holders shall, within three (3) Business Days of receipt of the Company’s
notice, advise whether the Holders wish to participate in the Offering and the extent of such participation; provided, however, that in the case of a “bought” deal, the Company shall provide the Investor at least 24 hours’ notice of
the Company announcing that it is conducting such an Offering and the Holders shall, prior to one-half hour before the Company’s announcement of the Offering, advise the Company as to whether it wishes to participate in the Offering and the
extent of such participation. If the Holders do not respond to notice of an Offering received from the Company within the time periods provided for in this Section 2(f), the Holders shall be deemed to have elected not to participate in such
Offering. Notwithstanding the foregoing, if issuance of New Securities to the Holders pursuant to this Section 2(f) would require the Company to seek approval of its stockholders under the rules of the New York Stock Exchange, the Company shall
not be required to seek approval of its stockholders for such issuance, and the pro rata portion of New Securities that the Holders may purchase shall be limited to the maximum amount of New Securities that the Holders would be able to purchase
without stockholder approval; provided, however, that if the Company is seeking its approval of its stockholders for any other reason in connection with the Company’s proposed issuance of New Securities, then the Company shall also seek
stockholder approval of the issuance to the Holders of their pro rata portion of the New Securities pursuant to this Section 2(f), and if, such stockholder approval is obtained, the Holders shall be entitled to purchase their full pro rata
portion of the New Securities. 
 (g) CPPIB hereby irrevocably and unconditionally agrees that at any meeting of the
stockholders of the Company at which action is to be taken by the stockholders with respect to the transactions contemplated by the Acquisition Agreement, including, without limitation, (i) the approval of an amendment to the Company’s
Certificate of Incorporation to increase the number of shares of Common Stock authorized for issuance thereunder and (ii) approval of the conversion of the Company’s convertible preferred stock issued to Petro-Hunt and Pillar Energy (the
“Transactions”), however called, including any adjournment or postponement thereof, and in 

  
 5 

 
connection with any written consent of the stockholders of the Company relating to the Transactions, CPPIB shall, in each case to the fullest extent that the Covered Shares are entitled to vote
thereon or consent thereto (x) appear at each such meeting or otherwise cause the Covered Shares to be counted as present thereat for purposes of calculating a quorum, and (y) vote (or cause to be voted), in person or by proxy, or deliver
(or cause to be delivered) a written consent covering, all of the Covered Shares in favor of the Transactions and any other action reasonably requested by the Company in furtherance thereof, submitted for the vote or written consent of stockholders.

 Section 3. Mandatory Shelf Registration. 

(a) The Company agrees to file with the Commission a shelf registration statement on Form S-3 or such other form under the Securities Act
then available to the Company providing for the resale pursuant to Rule 415 from time to time by the Holders of any and all Registrable Securities (including a prospectus, any amendments and supplements to such registration statement or prospectus,
including pre- and post-effective amendments, all exhibits thereto and all material incorporated by reference or deemed to be incorporated by reference, if any, in such registration statement, the “Mandatory Shelf Registration Statement”).
The Company agrees to use its reasonable best efforts to cause any Mandatory Shelf Registration Statement to be declared effective by the Commission within 365 days following the Closing Date. 

(b) The Company shall use its reasonable best efforts to cause any Mandatory Shelf Registration Statement to remain continuously
effective until the earlier of (i) the sale pursuant to a registration statement of all of the Registrable Securities covered by the Mandatory Shelf Registration Statement, (ii) the sale, transfer or other disposition pursuant to Rule 144
of all of the Registrable Securities covered by the Mandatory Shelf Registration Statement or (iii) the second anniversary of the effective date of the initial Mandatory Shelf Registration Statement (subject to extension pursuant to
Section 12 below); provided, however, that in the event that CPPIB has the right, pursuant to Section 2 hereof, to designate at least one (1) Director, such period under this clause (iii) shall be extended for as long as
CPPIB retains such right to designate at least one director. Any Mandatory Shelf Registration Statement shall provide for the resale from time to time, and pursuant to any method or combination of methods legally available to, and requested by, the
Holders of the Registrable Securities. 
 Section 4. Underwritten Public Offerings.  

(a) Following the expiration of the Lock-Up Period and for so long as CPPIB retains the right to designate at least one Director pursuant
to Section 2 of this Agreement, the Holders shall have the right to require the Company to conduct one (1) underwritten public offering of all or a portion of the Holders’ Registrable Securities in accordance with this Section 4
(an “Underwritten Offering”); provided, however, that in no event shall the Company be required to conduct an Underwritten Offering for less than a minimum of $10 million of Registrable Securities, in the aggregate (determined by
multiplying the number of Registrable Securities held by the Holders requesting the Underwritten Offering (the “Requesting Holders”) by the average of the closing price on the NYSE for the Common Stock for the ten trading days preceding
the date of such notice). In addition, if at any time and for so long as the Holders beneficially own 

  
 6 

 
(as determined in accordance with Rule 13d-3 under the Exchange Act, but excluding for this purpose any attribution of ownership of securities held by persons who are not affiliates of CPPIB)),
in the aggregate, over 15.0% of the issued and outstanding shares of Common Stock of the Company, the Holders shall be entitled to require the Company to conduct one (1) additional Underwritten Offering pursuant to the terms of this Agreement;
provided, however, that the Company shall not be required to effect more than two (2) Underwritten Offerings pursuant to this Section 4; and provided, further, that the Company shall not be required to effect more than
one (1) Underwritten Offering in any twelve (12) month period. 
 (b) Upon the request of the Requesting Holders
(which request shall specify the Registrable Securities intended to be included in such Underwritten Offering), the Company will use its reasonable best efforts to effect such Underwritten Offering in accordance with the procedures set forth in
Section 11 below; provided, however, that the Company shall have the right to defer such Underwritten Offering in accordance with Section 12 below. 
 (c) In addition, the Requesting Holders shall give notice to the Company of the managing underwriters for such proposed Underwritten Offering, such managing underwriters to be subject to the approval of
the Company, not to be unreasonably withheld. 
 (d) If an Underwritten Offering pursuant to this Section 4 is commenced,
but not completed for any reason (other than as a result of the Requesting Holders’ (i) determination not to complete the Underwritten Offering, (ii) failure to provide all necessary information regarding the Requesting Holders to the
Company or the underwriters or (iii) failure to satisfy any of the covenants or conditions contained in the underwriting agreement relating to such Underwritten Offering), such Underwritten Offering will not count as one of the Underwritten
Offerings that the Company is obligated to effect pursuant to this Section 4. 
 Section 5. Piggy-Back Registration
Rights. 
 (a) If the Company proposes to file, on its own behalf, a Registration Statement under the Securities Act on Form
S-1 or S-3 or similar forms available for use by the Company, other than pursuant to Section 3 of this Agreement or on Form S-8 in connection with a dividend reinvestment, employee stock purchase, option or similar plan or on Form S-4 in
connection with a merger, consolidation or reorganization, the Company shall give written notice to CPPIB at least ten (10) days before the filing with the Commission of such Registration Statement. Such notice shall offer to include in such
filing all or a portion of the Registrable Securities owned by the Holders. If any Holder desires to include all or a portion of its Registrable Securities in such Registration Statement, it shall give written notice to the Company within three
(3) business days after the date of receipt of such offer specifying the amount of Registrable Securities to be registered (for purposes of this Section 5, “Specified Shares”). The Company shall thereupon include in such filing
the Specified Shares, subject to priorities in registration set forth in this Agreement, and subject to its right to withdraw such filing, and shall use its reasonable best efforts to effect the registration under the Securities Act of the Specified
Shares. 

  
 7 

 (b) The right of any Holder to have Specified Shares included in any Registration Statement
in accordance with the provisions of this Section 5 shall be subject to the following conditions: 
 (1) The
Company shall have the right to require that the Holders agree to refrain from offering or selling any shares of Common Stock that it owns which are not included in any such Registration Statement in accordance with this Section 5 for any
reasonable time period, not to exceed ninety (90) days, as may be specified by any managing underwriter of the offering to which such Registration Statement relates. 

(2) If (A) a registration pursuant to this Section 5 involves an underwritten offering of the securities being
registered to be distributed (on a firm commitment basis) by or through one or more underwriters of recognized standing under underwriting terms appropriate for such a transaction and (B) the managing underwriter of such underwritten offering
shall inform the Company and the Holders by letter of its belief that the amount of Specified Shares requested to be included in such registration exceeds the amount which can be sold in (or during the time of) such offering within a price range
acceptable to the Company or a majority of such requesting stockholders, including the Holders, then the Company will include in such registration such amount of securities which the Company is so advised can be sold in (or during the time of) such
offering as follows: first, the securities being offered by the Company for its own account; second, any shares of common stock requested to be included in such Registration Statement pursuant to the Barclays RRA; third, the
Specified Shares and any shares of common stock requested to be included in such Registration Statement pursuant to the HALRES RRA and the Petro-Hunt RRA, pro rata on the basis of the amount of shares of Common Stock so proposed to be sold and so
requested to be included by all such stockholders, including the Holders; and fourth, the securities of the Company, if any, proposed to be included in the registration by any other holders of the Company’s securities (whether or not
such holders have contractual rights to include such securities in the registration). 
 The Company shall furnish the Holders with such number
of copies of the Prospectus as the Holders may reasonably request in order to facilitate the sale and distribution of their Specified Shares. 
 (c) Notwithstanding the foregoing, the Company in its sole discretion may determine not to file the Registration Statement or proceed with the offering as to which the notice specified in
Section 5(a) is given without liability to the Holders. 
 Section 6. Participation in Underwritten Offering.
No Holder may participate in any Underwritten Offering unless such Holder (a) agrees to sell its Registrable Securities included in such registration on the basis provided in any underwriting arrangements approved by the holders of at least a
majority of the Registrable Securities to be included in such registration, or by a Person appointed by such holders to act on their behalf to approve such arrangements, and (b) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, provided, however, that no Holder shall be required to make any representations or warranties to, or
agreements with, the Company or any underwriters other than such representations, warranties or agreements as are customary and reasonably requested by the underwriters.

 Section 7. Exclusive Registration Rights and Transfer. 

The rights of CPPIB, as the initial Holder under this Agreement, may upon notice to the Company be transferred to any of CPPIB’s
affiliates to which any Registrable Securities are transferred; provided that any such transferee shall have executed and delivered to the Company an agreement in form and substance reasonably acceptable to the Company whereby such transferee agrees
to be bound by the terms and conditions of this Agreement as if such transferee were an original party hereto. Except as provided in this Section 7, the rights granted under this Agreement are granted specifically to and for the benefit of
CPPIB and shall not pass to any other transferee of Registrable Securities. From and after the date of this Agreement, the Company will not, without the prior written consent of CPPIB, enter into any agreement with respect to its securities that
violates the rights granted to CPPIB in this Agreement. The foregoing shall not restrict or prevent the Company from entering into any other agreement with any party pertaining to the registration by the Company of such party’s Common Stock,
provided, however, that no such agreement shall grant to any Person registration rights that are superior or preferential to the rights granted to the Holders hereunder or that would otherwise frustrate the purposes of this Agreement.
Except as set forth in Schedule 2 attached hereto, the Company represents and warrants to CPPIB that, as of the date hereof, the Company is not a party to any agreement, other than this Agreement, pertaining to the registration by the Company of
Common Stock. 
 Section 8. Expenses. The Company shall bear all the expenses in connection with any Registration
Statement under this Agreement, other than transfer taxes payable on the sale of Shares, the fees and expenses of counsel engaged by the Holders and fees, commissions and discounts of brokers, dealers and underwriters. 

Section 9. Recall of Prospectuses, etc. With respect to a Registration Statement or amendment thereto filed pursuant to this
Agreement, if, at any time, the Company notifies the Holders that an amendment to such Registration Statement or an amendment or supplement to the prospectus included therein is necessary or appropriate, the Holders will forthwith cease selling and
distributing Shares thereunder and will, upon the Company’s request, forthwith redeliver to the Company all copies of such Registration Statement and prospectuses then in its possession or under its control. The Company will use its reasonable
best efforts to cause any such amendment or supplement to become effective as soon as practicable and will furnish the Holders with a reasonable number of copies of such amended or supplemented prospectus (and the period during which the Company is
required to use its best efforts to maintain such Registration Statement in effect pursuant to this Agreement will be increased by a number of days equal to the number of days in the period from the date on which any Holder was required to cease
selling and distributing Shares thereunder to the date on which the Company delivers copies of such effective amendment or supplement to each Holder). 
 Section 10. Cooperation. The Company shall be entitled to require the Holders to cooperate with the Company in connection with a registration of Registrable Securities pursuant to this
Agreement and each Holder will furnish (i) such information concerning such Holder as may be required by the Company or the Commission in connection therewith and (ii) such representations, undertakings and agreements as may be required by
the Commission in connection therewith.

 Section 11. Underwritten Offering Procedures. Upon the receipt of a request for
any Underwritten Offering pursuant to Section 4 of this Agreement, the Company will use its reasonable best efforts to effect such Underwritten Offering, and pursuant thereto the Company will as expeditiously as possible: 

(a) To the extent necessary to register any Registrable Securities that are not registered under the Mandatory Shelf Registration
Statement, amend the Mandatory Shelf Registration Statement to add such Registrable Securities or prepare and file with the Commission a new registration statement on an appropriate form under the Securities Act (an “Additional Registration
Statement” and, together with the Mandatory Shelf Registration Statement, a “Registration Statement”)) and use its reasonable best efforts to cause such Additional Registration Statement to become effective at the earliest practicable
date, but in no event later than thirty (30) days from the Company’s receipt of the Holder’s request to have Registrable Securities included such Registration Statement; provided, that before filing any Additional Registration
Statement or any prospectus or any amendments or supplements to any Registration Statement or any prospectus, including documents incorporated by reference after the initial filing of any Registration Statement, the Company will promptly furnish to
the Requesting Holders and the underwriters copies of all such documents proposed to be filed, which documents will be subject to the review of the Requesting Holders and the underwriters, and the Company will not file any Registration Statement or
amendment thereto, or any prospectus or any supplement thereto (including such documents incorporated by reference) to which the Requesting Holders or the underwriters shall reasonably object in light of the requirements of the Securities Act and
any other applicable laws and regulations. 
 (b) Prepare and file with the Commission such amendments and post-effective
amendments to any Registration Statement as may be necessary to keep such Registration Statement effective for the applicable period set forth in Section 3(b) or, with respect to any Additional Registration Statement, for such period of time as
is necessary to complete an Underwritten Offering pursuant to this Agreement; cause the related prospectus to be filed pursuant to Rule 424(b) (or any successor provision) under the Securities Act; cause such prospectus to be supplemented by any
required prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424(b) (or any successor provision) under the Securities Act; and comply with the provisions of the Securities Act with respect to the disposition of all securities
covered by such Registration Statement during the applicable period in accordance with the intended methods of disposition set forth in such Registration Statement or prospectus or supplement to such prospectus. 

(c) Notify the Requesting Holders and the managing underwriters promptly, and (if requested by any such Person) confirm such advice in
writing, (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (ii) of any request
by the Commission for amendments or supplements to a Registration Statement or related prospectus or for additional information, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement
or the initiation of any proceeding for that purpose, (iv) if at any time the representations and warranties of the Company contemplated by paragraph (j) cease to be true and correct, (v) of the receipt by the Company of any
notification with respect to the suspension of qualification of any 

  
 10 

 
of the Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose, (vi) of the happening of any event which requires the making of any changes
in a Registration Statement or related prospectus so that such documents will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not
misleading and (vii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate or that there exist circumstances not yet disclosed to the public which make further sales
under such Registration Statement inadvisable pending such disclosures and post-effective amendment. 
 (d) Make reasonable
efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement, or the lifting of any suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction, at the earliest possible
moment. 
 (e) If requested by the managing underwriters or the Requesting Holders, immediately incorporate in a prospectus
supplement or post-effective amendment such information as the managing underwriters and the Requesting Holders reasonably request be included therein relating to such sale and distribution of Registrable Securities, including, without limitation,
information with respect to the number of shares of Registrable Securities being sold to such underwriters and the purchase price being paid therefor by such underwriters and with respect to any other terms of the Underwritten Offering; make all
required filings of such prospectus supplement or post-effective amendment as soon as practicable after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and supplement or make amendments to
any Registration Statement to the extent reasonably requested by the Requesting Holders or any underwriter of such Registrable Securities. 
 (f) Furnish to the Requesting Holders and each managing underwriter without charge, at least one signed copy of the Registration Statement, any post-effective amendment thereto, including financial
statements and schedules, all documents incorporated therein by reference and all exhibits (including those incorporated by reference). 
 (g) Deliver without charge to the Requesting Holders and the underwriters as many copies of the prospectus or prospectuses (including each preliminary prospectus) and any amendment or supplement thereto
as such Persons may reasonably request; and the Company consents to the use of such prospectus or any amendment or supplement thereto by such Requesting Holders and the underwriters, if any, in connection with the offer and sale of the Registrable
Securities covered by such prospectus or any amendment or supplement thereto. 
 (h) Prior to any public offering of Registrable
Securities, register or qualify or cooperate with the Requesting Holders, the underwriters, if any, and respective counsel in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities or
Blue Sky laws of such jurisdictions as the Requesting Holders or an underwriter reasonably requests in writing; keep each such registration or qualification effective during the period the Registration Statement is required to be kept effective and
do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the applicable Registration Statement; provided, however, that the Company will
not be required in connection therewith or as a condition thereto to qualify generally to do business or subject itself to general service of process in any such jurisdiction where it is not then so subject. 

  
 11 

 (i) Upon the occurrence of any events described in paragraph (c)(ii) through (c)(vii) above,
prepare, to the extent required, a supplement or post-effective amendment to the applicable Registration Statement or related prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter
delivered to the purchaser of the Registrable Securities being sold thereunder, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. 
 (j) Enter into such customary and reasonable agreements (including
an underwriting agreement) and take all such other actions reasonably necessary in connection therewith in order to expedite or facilitate the disposition of such Registrable Securities and in such connection, whether or not an underwriting
agreement is entered into and whether or not the Registrable Securities to be covered by such registration are to be offered in an underwritten offering: (i) make such representations and warranties to the Requesting Holders as to the
Registration Statement, prospectus and documents incorporated by reference, if any, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and confirm the same if and when requested; (ii) use
reasonable best efforts to obtain opinions of counsel to the Company and updates thereof with respect to the Registration Statement and the prospectus in the form, scope and substance which are customarily delivered in underwritten offerings;
(iii) in the case of an underwritten offering, enter into an underwriting agreement in form, scope and substance as is customary in underwritten offerings and obtain opinions of counsel to the Company and updates thereof (which counsel and
opinions (in form, scope and substance) shall be reasonably satisfactory to the managing underwriters and the Requesting Holders) addressed to the Requesting Holders and the underwriters covering the matters customarily covered in opinions delivered
in underwritten offerings and such other matters as may be reasonably requested by the Requesting Holders and such underwriters; (iv) use reasonable best efforts to obtain comfort letters and updates thereof from the Company’s independent
certified public accountants addressed to the Requesting Holders and the underwriters such letters to be in customary form and covering matters of the type customarily covered in comfort letters by accountants in connection with underwritten
offerings; (v) any underwriting agreement entered into shall set forth in full the indemnification provisions and procedures customarily included in underwriting agreements in underwritten offerings; and (vi) the Company shall deliver such
documents and certificates as may be reasonably requested by the Requesting Holders and the managing underwriters to evidence compliance with clause (i) above and with any customary conditions contained in the underwriting agreement or other
agreement entered into by the Company. The above shall be done at each closing under such underwriting or similar agreement or as and to the extent required thereunder. 
 (k) Make available for inspection by a representative of the Requesting Holders, any underwriter participating in any disposition pursuant to such registration, and any attorney or accountant retained by
the Requesting Holders or such underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors and employees to supply all information reasonably requested
by any such representative, underwriter, attorney or accountant in connection with such registration; 

  
 12 

 
provided, that any records, information or documents that are designated by the Company in writing as confidential shall be kept confidential by such Persons unless disclosures of such
records, information or documents is required by court or administrative order after prior written notice to the Company and cooperation with it in seeking a protective order. 
 (l) Otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Commission and make generally available to its security holders earning statements satisfying the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder, no later than 90 days after the end of any 12-month period (i) commencing at the end of any fiscal quarter in which Registrable Securities are sold to underwriters
in a firm or best efforts underwritten offering and (ii) beginning with the first day of the Company’s first fiscal quarter next succeeding each sale of Registrable Securities after the effective date of a Registration Statement, which
statements shall cover said 12-month periods. 
 (m) Use its reasonable best efforts to list all Registrable Securities covered
by the Registration Statement on the New York Stock Exchange and any other securities exchange or trading market on which any of the equity securities of the Company of the same class as the Registrable Securities are then listed. 

(n) For so long as either (i) CPPIB retains the right to designate at least one Director pursuant to Section 2 or (ii) the
Company is required to maintain the effectiveness of the Mandatory Shelf Registration Statement pursuant to Section 3 hereof, maintain the effectiveness of the registration of the Common Stock under the Exchange Act and use its reasonable best
efforts to prepare and file in a timely manner all documents and reports required by such Act. 
 (o) If the Company, in the
exercise of its reasonable judgment, objects to any change requested by the Requesting Holders or the underwriters to any Registration Statement or prospectus or any amendments or supplements thereto (including documents incorporated or to be
incorporated therein by reference) as provided for in this Section 11, the Company shall not be obligated to make any such change and such Requesting Holders may withdraw their Registrable Securities from such registration or Underwritten
Offering, in which event (i) the Company shall pay all registration expenses (including its counsel fees and expenses) incurred in connection with such Registration Statement or amendment thereto or prospectus or supplement thereto, and
(ii) in the case of an Underwritten Offering being effected pursuant to Section 4, such registration shall not count as one of the Underwritten Offerings the Company is obligated to effect pursuant to Section 4. 

Section 12. Suspension Period.  
 (a) Subject to the to the provisions of this Section 12 and a good faith determination by a majority of the Board that it is in the best interests of the Company to suspend the use of the Mandatory
Shelf Registration Statement, following the effectiveness of such Mandatory Shelf Registration Statement (and the filings with any international, federal or state securities commissions), the Company, by written notice to the Holders, may direct the
Holders to suspend sales of the Registrable Securities pursuant to such Mandatory Shelf Registration Statement for such times as the Company reasonably may determine is necessary and advisable (but in no event for more than 60 days in any 90-day
period or more than 120 days in any 12-month 

  
 13 

 
period), if any of the following events shall occur: (i) an underwritten public offering of Common Stock by the Company if the Company is advised by the underwriters that the concurrent
resale of the Registrable Securities by the Holders pursuant to the Mandatory Shelf Registration Statement would have a material adverse effect on the Company’s offering, or (ii) pending discussions relating to a transaction or the
occurrence of an event (1) that would require additional disclosure of material information by the Company in the Mandatory Shelf Registration Statement and that has not been so disclosed, and (2) as to which the Company has a bona fide
business purpose for preserving confidentiality. Upon the earlier to occur of (A) the Company delivering to the Holders an End of Suspension Notice, as hereinafter defined, or (B) the end of the maximum permissible suspension period, the
Company shall use its commercially reasonable efforts to promptly amend or supplement the Mandatory Shelf Registration Statement on a post-effective basis, if necessary, or to take such action as is necessary to make resumed use of the Mandatory
Shelf Registration Statement compatible with the Company’s best interests, as applicable, so as to permit the Holders to resume sales of the Registrable Securities as soon as possible. 

(b) In the case of an event that causes the Company to suspend the use of a Mandatory Shelf Registration Statement (a “Suspension
Event”), the Company shall give written notice (a “Suspension Notice”) to the Holders to suspend sales of the Registrable Securities, and such notice shall state that such suspension shall continue only for so long as the
Suspension Event or its effect is continuing and the Company is taking all reasonable steps to terminate suspension of the effectiveness of the Mandatory Shelf Registration Statement as promptly as possible. The Holders shall not effect any sales of
the Registrable Securities pursuant to any Mandatory Shelf Registration Statement at any time after it has received a Suspension Notice from the Company and prior to receipt of an End of Suspension Notice (as defined below). If so directed by the
Company, each Holder will deliver to the Company (at the expense of the Company) all copies other than permanent file copies then in such Holder’s possession of the Prospectus covering the Registrable Securities at the time of receipt of the
Suspension Notice. The Holders may recommence effecting sales of the Registrable Securities pursuant to the Mandatory Shelf Registration Statement (or such filings) following further notice to such effect (an “End of Suspension Notice”)
from the Company, which End of Suspension Notice shall be given by the Company to the Holders in the manner described above promptly following the conclusion of any Suspension Event and its effect. 

(c) Notwithstanding any provision herein to the contrary, if the Company shall give a Suspension Notice pursuant to this Section 12
with respect to the Mandatory Shelf Registration Statement, the Company agrees that it shall extend the period of time during which such Mandatory Shelf Registration Statement shall be maintained effective pursuant to this Agreement by the number of
days during the period from the date of the giving of the Suspension Notice to and including the date when Holders shall have received the End of Suspension Notice and copies of the supplemented or amended Prospectus necessary to resume sales;
provided such period of time shall not be extended beyond the date that Shares or Additional Shares are not Registrable Securities. 
 (d) In addition, upon the occurrence of any Suspension Event, the Company may defer any Underwritten Offering requested pursuant to Section 4 of this Agreement for a period of up to sixty
(60) days upon written notice to the Requesting Holders; provided, however, that the Company may not utilize this right with respect to a request under Section 4 of this Agreement more than once in any twelve (12) month period.

  
 14 

 Section 13. Indemnification. 

(a) In the event of any registration of any securities under the Securities Act pursuant to this Agreement, the Company will indemnify
and hold harmless each Holder, any underwriter and each other Person, if any, who controls any Holder or an underwriter within the meaning of the Securities Act, and the respective officers, directors, partners, members and employees of any Holder,
any underwriters and controlling Persons, from and against any and all losses, claims, damages or liabilities, joint or several, to which any such indemnified Person may become subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or action in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in a Registration Statement or preliminary prospectus or final or summary
prospectus contained therein, or any amendment or supplement thereto, and any other document prepared by the Company and provided to Holders for their use in connection with the registered offering, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein (in the case of a prospectus or preliminary prospectus, in the light of the circumstances under which they were made)
not misleading, and will reimburse such indemnified Persons for any reasonable legal and other expenses incurred by them in connection with investigating or defending any such action or claim, excluding any amounts paid in settlement of any
litigation, commenced or threatened, if such settlement is effected without the prior written consent of the Company; provided, however, that the Company will not be liable to an indemnified Person in any such case to the extent that
any such loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or omission or alleged untrue statement or omission made in a Registration Statement, preliminary prospectus or final or summary prospectus or any
amendment or supplement thereto or other document, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such indemnified Person, specifically for use in the preparation thereof. 

(b) In the event of any registration of securities under the Securities Act pursuant to this Agreement, each Holder will indemnify and
hold harmless the Company, each of its directors and officers, any underwriter and each other Person, if any, who controls the Company or such underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities
to which any such indemnified Person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or action in respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in such Registration Statement or preliminary prospectus or final or summary prospectus contained therein, or any amendment or supplement thereto, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein (in the case of a prospectus or preliminary prospectus, in light of the circumstances under which they were made) not
misleading, and will reimburse such indemnified Persons for any reasonable legal and other expenses incurred by them in connection with investigating or defending any such action or claim, excluding any amounts paid in settlement of any litigation,
commenced or threatened, if 

  
 15 

 
such settlement is effected without the prior written consent of the Holders; provided, however, that any liability or obligation of the Holders under this Section 13(b)
shall only apply if, and to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission therein made in reliance upon and in
conformity with written information furnished to the Company by or on behalf of the Holders specifically for use in the preparation thereof. Notwithstanding the foregoing, the amount of the indemnity provided by the Holders pursuant to this
Section 13 shall not exceed the net proceeds received by the Holders in the related registration and sale. 
 (c) Promptly
after receipt by a party entitled to indemnification under Section 13(a) or 13(b) hereof of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under
either of such subsections, notify the indemnifying party in writing of the commencement thereof. In case any such action is brought against the indemnified party and it shall so notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in, and, to the extent that it so chooses, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party that it so
chooses, such indemnifying party shall not be liable for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof, provided, however, that (i) if the indemnifying
party fails to take reasonable steps necessary to diligently defend such claim within twenty (20) days after receiving notice from the indemnified party that the indemnified party believes the indemnifying party has failed to take such steps or
(ii) if the defendants in any such action include the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to
the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume its own legal defense and otherwise to participate in the defense of such action, with any expenses and fees related to such
participation to be reimbursed by the indemnifying party. The indemnity and contribution agreements in this Section 13 are in addition to any liabilities which the indemnifying parties may have pursuant to law. 

(d) If the indemnification provided for in this Section 13 from the indemnifying party is unavailable to an indemnified party
hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein, or is insufficient to hold the indemnified party harmless therefrom, then the indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified
parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified parties shall be
determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information
supplied by, such indemnifying party or indemnified parties, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by an indemnified party as a result of
the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in this Section 13, any legal or other fees or expenses reasonably incurred by such party in connection
with any investigation or proceeding. 

  
 16 

 The parties hereto agree that it would not be just and equitable if contribution pursuant to
this Section 13 were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraph. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

Section 14. Sales under Rule 144. With a view to making available to the Holders the benefits of Rule 144 promulgated under
the Securities Act and any other similar rule or regulation of the Commission that may at any time permit the Holders to sell the Registrable Securities without registration, the Company agrees for so long as either (i) CPPIB retains the right
to designate at least one Director pursuant to Section 2 of this Agreement or (ii) the Company is required to maintain the effectiveness of the Mandatory Shelf Registration Statement pursuant to Section 3 hereof to: 

(a) make and keep available adequate current public information, as those terms are understood and defined in Rule 144 (or any successor
provision); 
 (b) use its reasonable best efforts to file with the Commission in a timely manner all reports and other
documents required to be filed by the Company under the Securities Act and the Exchange Act; and 
 (c) furnish to the Holders
forthwith upon request (i) a written statement by the Company that it has complied with the foregoing requirements and (ii) such other information as may be reasonably requested by any Holder in availing itself of any rule or regulation of
the Commission which permits the selling of any such securities without registration.
