 NOW, THEREFORE, in consideration of the premises, the mutual covenants hereinafter set forth, and other good and valuable consideration, the Company and you hereby agree as follows: 

Article 1. Award 
 The
Company hereby grants you, as a matter of separate inducement and agreement, and not in lieu of salary or other compensation for services, [TOTAL SHARES GRANTED] Performance Share Units (the “Target Award”), on the terms and
conditions hereinafter set forth. The number of Performance Share Units (“PSUs”) that you may earn under this Agreement shall range from 0% to 200% of the Target Award (the “Earned PSUs”), as determined by the

Capitalized terms used in this Agreement that are not defined herein shall have the meanings assigned to such terms in the Plan and the
Program. This Agreement is subject to, and the Company and you agree to be bound by, all of the terms and conditions of the Plan and the Program as the same exist at the time this Agreement became effective. The Plan and the Program shall control in
the event there is any express conflict between the terms hereof and the Plan or the Program and with respect to such matters as are not expressly covered in this Agreement. The Company hereby reserves the right to alter, amend, modify, restate,

 Article 2. Measurement Period, Performance Period and Award Period 

For all purposes of this Agreement, “Measurement Period” means January 1, [YEAR] through
December 31, [YEAR], “Performance Period” means January 1, [YEAR] through December 31, [YEAR] and “Award Period” means January 1, [YEAR] through December 31,
[YEAR].  
 Article 3. Achievement of Performance Measure(s) 

The number of Earned PSUs to be earned under this Agreement shall be based upon the achievement of the following Performance Period
performance measure(s) set by the Committee, and measured with respect to the Measurement Period as of December 31, [YEAR]: 
 [PERFORMANCE MEASURE(S) AND DETERMINATION OF ACHIEVEMENT] 
 The number of Earned PSUs for
achievement above threshold levels but between the levels shown above will be calculated using straight line interpolation between percentage amounts to the extent necessary. No award is earned if performance is below the threshold level. The
maximum award achievement is 200%. 
 Article 4. Termination/Forfeiture Provisions 

Except as otherwise provided below in this Article 4, you shall be eligible for payment of Earned PSUs, as determined in Article 3, only
if your employment with the Company or a Related Company continues through the end of the Award Period. 

In the event of your termination of employment as a result of death or disability prior to the end of the Award
Period, you (or your beneficiary) will be entitled to receive a payout of Earned PSUs on the same basis as other Participants, provided that (1) such amount shall be prorated for the number of full months worked during the Award Period as a
percentage of the total number of full months in the Award Period and (2) payout shall be made within
2 1/2 months after the later of the termination or
the certification by the Committee of payouts for the Award Period, notwithstanding the requirement applicable generally that no payout is due unless the you remain employed until the end of the Award Period. In no event, however, will payout occur
later than the time provided in Article 6. 
 The effect of a Change of Control on PSUs shall be governed by the terms of
a Company change of control policy or agreement as then in effect and applicable to the PSUs. In the event no policy or agreement addresses the effect of a Change of Control on the PSUs, the terms of the Plan shall govern. 

Article 5. Rights as a Stockholder 
 During the Award Period, you shall have no rights of a stockholder with respect to the PSUs or the Earned PSUs. Notwithstanding the foregoing, you shall be entitled to receive any dividend equivalents
declared by the Board, as provided in the Program. 
 Article 6. Form and Timing of Payment 

Except as set forth in Article 4 or in the Program, payment of Earned PSUs shall be made in the form of shares of
Common Stock within 2 1/2 months following the close
of the Award Period. The Company shall direct its transfer agent to issue to you, in uncertificated form, the number of unrestricted shares of Common Stock that are payable to you under this Agreement.

 Article 7. Nontransferability 

PSUs may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent
and distribution. Your rights under this Agreement shall be exercisable during your lifetime only by your or your legal representative. 

Article 8. Administration 

It is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate
to the administration of the Plan, the Program and this Agreement, all of which shall be binding upon you. 
 Article 9. Clawback
Policy. 
 The PSUs and any shares of Common Stock issued thereunder shall be subject to potential cancellation, rescission,
payback, recoupment or other action in accordance with the terms of the Company’s clawback policy (the “Policy”), as then in effect and as it may be amended from time to time, to the extent the Policy applies to the PSUs and
any shares of Common Stock issued thereunder (including a Policy implemented or amendments made thereto after the Grant Date for the PSUs). By accepting the Award, you agree to execute any additional documents to effect the Company’s
application, implementation and enforcement of such Policy with respect to the PSUs and any shares of Common Stock issued thereunder. 

Article 10. Withholding Taxes 
 No later than the date as of which an amount first becomes includable in your gross income for federal income tax purposes or otherwise with respect to any PSUs or Earned PSUs, you shall pay to the
Company or a Related Company, as applicable, or make arrangements satisfactory to the Company or a Related Company regarding the payment of, any federal, state, local, or foreign taxes of any kind required by law to be withheld by the Company or a
Related Company with respect to such amount (the “Mandatory Withholding Taxes”). The obligations of the Company hereunder shall be conditional on such payment or arrangements. Notwithstanding the foregoing, to the maximum extent
permitted by applicable law, the Company has the right to retain, without notice to you, from the total number of shares of Common Stock issuable and deliverable to you pursuant to this Agreement, or from salary or other amounts payable to you, the
number of shares or cash having a value not less than the Mandatory Withholding Taxes; the Company currently intends to satisfy such Mandatory Withholding Taxes by retaining shares of Common Stock otherwise issuable under this Award (up to the
minimum statutory amount required to be withheld by the Company). 

  
 Page 3 of 5

 Regardless of any action the Company takes with respect to any or all of the Mandatory
Withholding Taxes, you acknowledge that the ultimate liability for all withholding taxes legally due by you is and remains your responsibility and that the Company (a) makes no representations or undertakings regarding the treatment of any
withholding taxes in connection with any aspect of the Earned PSUs, including the grant or other vesting of the PSUs or Earned PSUs, the subsequent sale of shares of Common Stock received upon vesting of the Earned PSUs, if any, and the receipt of
any dividends or dividend equivalents; and (b) does not commit to structure the terms of the Award or any aspect of the Award to reduce or eliminate your liability for withholding taxes. 
 Article 11. Miscellaneous 
 (a) You understand and acknowledge that you are
one of a limited number of employees of the Company and its Related Companies who have been selected to receive a grant of PSUs and that your Award is considered Company confidential information. You hereby covenant and agree not to disclose the
Award of PSUs pursuant to this Agreement to any other person except (i) your immediate family and legal or financial advisors who agree to maintain the confidentiality of this Agreement, (ii) as required in connection with the
administration of this Agreement and the Plan as it relates to this Award or under applicable law, and (iii) to the extent the terms of this Award have been publicly disclosed. 

(b) The grant of PSUs to you in any year shall give you neither any right to similar grants in future years nor any right to be retained
in the employ of the Company or its Related Companies, such employment being terminable to the same extent as if the Program and this Agreement were not in effect. The right and power of the Company and its Related Companies to dismiss or discharge
you is specifically and unqualifiedly unimpaired by this Agreement. 
 (c) Each notice relating to this Agreement shall be in
writing and delivered in person or by mail to the Company at its office, 6001 36th Avenue West, Everett, WA 98203-1264, to the attention of the Company’s Secretary or at such other address as the Company may specify in writing to you by a
notice delivered in accordance with this paragraph. All notices to you shall be delivered to you at the most recent address for you in the Company’s records or at such other address as you may specify in writing to the Secretary of the Company
by a notice delivered in accordance with this paragraph. 
 (d) This Agreement, including the provisions of the Plan and the
Program incorporated by reference herein, comprises the whole Agreement between the parties hereto with respect to the subject matter hereof, and shall be governed by and construed in accordance with the laws of the State of Washington, U.S.A.,
without reference to principles of conflicts of law. This Agreement shall become effective when it has been executed or accepted electronically by the Company and you. For purposes of litigating any dispute that arises directly or indirectly from
the relationship of the parties evidenced by this Agreement, the parties hereby submit to and consent to the exclusive jurisdiction of the State of Washington, U.S.A., and agree that such litigation shall be conducted only in the courts of
Washington, U.S.A., or the federal courts for the United States for the Western District of Washington, and no other courts where this grant is made and/or to be performed. 
 (e) This Agreement shall inure to the benefit of and be binding upon each successor of the Company and, to the extent specifically provided herein and in the Plan and the Program, shall inure to the
benefit of and shall be binding upon your heirs, legal representatives, and successors. 

  
 Page 4 of 5

 (f) If any provision of this Agreement shall be invalid or unenforceable, such invalidity or
unenforceability shall not affect the validity and enforceability of the remaining provisions of this Agreement. 
 (g) This
Agreement may be executed in separate counterparts, each of which when so executed and delivered will be an original, but all of which together will constitute one and the same instrument. In pleading or proving this Agreement, it will not be
necessary to produce or account for more than one such counterpart. 
 (h) The Company may, in its sole discretion, deliver any
documents related to the PSUs, or future PSUs (if any) that may be granted under the Program, by electronic means or request your consent to participate in the Program by electronic means. You hereby consent to receive such documents by electronic
delivery and agree to participate in the Program through an on-line or electronic system established and maintained by the Company or another third party designated by the Company. 

(i) Payments made pursuant to this Agreement are intended to qualify for an exemption from Section 409A of the Code. Notwithstanding
any other provision in this Agreement, the Program and the Plan, the Company, to the extent it deems necessary or advisable in its sole discretion, reserves the right, but shall not be required, to unilaterally amend or modify this Agreement, the
Program or the Plan so that the Award granted hereunder to you qualifies for exemption from or complies with Section 409A; provided, however, that the Company makes no representations that this Agreement or the Award shall be exempt from or
comply with Section 409A and makes no undertaking to preclude Section 409A from applying to the Award. By accepting this Award, you shall be deemed to have waived any claim against the Company and its affiliates with respect to any such
tax, economic and legal consequences. Also notwithstanding the foregoing, if at the time of a scheduled vesting or payout date under this Agreement, you are a “specified employee” of the Company within the meaning of that term under
Section 409A and as determined by the Company, and payment would be treated as a payment made on “separation from service” within the meaning of that term under Section 409A, then, if such delayed commencement is otherwise
required in order to avoid a prohibited distribution under Section 409A, the payment shall be delayed until the date which is six months after the date of such separation from service or if earlier the date of your death. 

IN WITNESS WHEREOF, this Agreement is executed by you and by the Company through its duly authorized officer as of the Grant Date
first above written.

Damages” means, with respect to a Company Title Breach, an amount determined by the following calculation: (i) a fraction, (A) the numerator of which is the decrease in the Fair Market Value of the Idaho Properties, as a whole

assuming for such purposes that such Company Title Breach had not occurred); multiplied by (ii) $276,500,000.00 (less the aggregate amount of any prior decreases in value of the Idaho Properties related to prior Company Title Breaches for which
Investor has made valid Claims); multiplied by (iii) 0.15; multiplied by (iv) a fraction, (A) the numerator of which is the number of Shares owned by Investor at the time a Claim is made by Investor under

the Company Title Breach. Solely by way of example, if a Company Title Breach is determined to have decreased the Fair Market Value of the Idaho Properties by $20,000,000 (as of the Closing Date) and the Fair Market Value of the Idaho Properties (as
of the Closing Date) is determined to be $400,000,000, the Property Damages would be equal to (I) 0.05 (e.g., $20,000,000 divided by $400,000,000); multiplied by (II) 

  
 7 

 
$276,500,000.00; multiplied by (III) 15% (assuming, at such time, Investor continues to hold the same number of Shares Investor held on the Closing Date).

defect in title with respect to the Core Idaho Properties that is materially adverse to the Fair Market Value of the Core Idaho Properties as of the date hereof, taken as a whole; provided, that any such lien, claim, encumbrance, exception or

subject to a voting agreement or similar Lien, or (ii) in the absence of such a governing body, at least a majority ownership interest.

Section 8.01(a) or (c) prior to the expiration of the applicable survival period, then the party seeking indemnification in respect of such claim shall continue to have the right to be indemnified (to the extent such
indemnification is available pursuant hereto) with respect to such indemnification claim until such claim has been satisfied or resolved pursuant to this Article VIII (which may, for the avoidance of doubt, include a determination that no
indemnification is warranted). 
 Section 8.02. Indemnification. 

(a) Subject to this Article VIII, from and after the Closing Date, the Company hereby indemnifies each Investor Indemnitee against
and agrees to hold each of them harmless (without duplication) from any and all actual and direct Damages incurred or suffered by any Investor Indemnitee to the extent arising out of or based upon (i) any representation or warranty of the
Company contained in this Agreement not being true and correct when made or deemed made or (ii) any breach or nonperformance of any covenant or agreement made or to be performed by the Company pursuant to this Agreement (other than
representations or warranties which are solely the subject of the preceding clause (i)). 
 (b) No indemnification by the
Company shall be due and payable under Section 8.02(a)(i) in respect of any Company Breach or Company Title Breach unless and until the cumulative amount of all Damages arising out of or resulting from all such Company Breaches and
Company Title Breaches exceeds the Basket Amount, whereupon the Company will be obligated to indemnify the Investor Indemnitees for the cumulative amount of all Damages incurred or suffered by the Investor Indemnitees, including those not in excess
of the Basket Amount. The Company shall not be obligated to indemnify any Investor Indemnitee for Damages arising out of or resulting from all Company Breaches and Company Title Breaches under this Agreement in an aggregate amount in excess of the
Maximum Amount. The limitations on indemnification set forth in this Section 8.02(b) shall not be applicable to (i) any Company Exception Breach (and the Investor Indemnitees will be entitled to indemnification with respect to any
Company Exception Breach without regard to any Basket Amount or Maximum Amount) and (ii) any claim based solely upon fraud. Notwithstanding any other provision in this Agreement to the contrary, under no circumstances will any amount payable by
the Company to an Investor Indemnitee under Section 8.02(a)(i) with respect to a Company Title Breach be greater than the Property Damages arising out of or based upon such Company Title Breach. 

  
 37 

 (c) Subject to this Article VIII, from and after the Closing Date, Investor hereby
indemnifies each Company Indemnitee against and agrees to hold each of them harmless (without duplication) from any and all Damages incurred or suffered by any Company Indemnitee to the extent arising out of or based upon (i) any representation
or warranty of Investor contained in this Agreement not being true and correct when made or deemed made or (ii) any breach or nonperformance of any covenant or agreement made or to be performed by Investor pursuant to this Agreement (other than
representations or warranties which are solely the subject of the preceding clause (i)). 
 (d) Investor shall not be obligated
to indemnify any Company Indemnitee for Damages arising out of or resulting from all Investor Breaches under this Agreement in an aggregate amount in excess of the Maximum Amount. The limitations on indemnification set forth in this
Section 8.02(d) shall not be applicable to (i) any Investor Exception Breach (and the Company Indemnitees will be entitled to indemnification with respect to any Investor Exception Breach without regard to any Maximum Amount) and
(ii) any claim based solely upon fraud. 
 Section 8.03. Procedures. 

(a) The Investor Indemnitee or Company Indemnitee seeking indemnification under Section 8.02 (the “Indemnified
Party”) agrees to give prompt written notice in accordance herewith (the “Claim Notice”) to the party or parties against whom indemnity is sought (the “Indemnifying Party”) of the assertion or discovery of
any claim or demand, or the commencement of any suit, action, investigation or proceeding (any such claim, demand, suit, action, investigation or proceeding, a “Claim”) in respect of which indemnity may be sought under
Section 8.02 (and such notice shall be within ten Business Days following the earlier of the Indemnified Party becoming aware of the Claim or receipt by the Indemnified Party of notice of the Claim, or within such shorter time as may be
necessary to give the Indemnifying Party a reasonable opportunity to respond to such Claim, and include a statement specifying the basis of such Claim) and will provide the Indemnifying Party such information with respect thereto in its possession
that the Indemnifying Party may reasonably request; provided, however, that failure to give such notification within the time provided shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party
shall have been actually prejudiced as a result of such failure; provided, further, that it is understood that, prior to seeking the indemnification provided hereunder, the Indemnified Party shall provide the Indemnifying Party with a
Claim Notice with respect thereto. The Claim Notice shall set forth in reasonable detail (i) the facts and circumstances giving rise to such claim for indemnification, (ii) the nature of the Damages suffered or incurred or expected to be
suffered or incurred, (iii) a reference to the provisions of this Agreement in respect of which such Damages have been suffered or incurred or are expected to be suffered or incurred, (iv) the amount of Damages actually suffered or
incurred, and, to the extent the Damages have not yet been suffered or incurred, a good faith estimate, to the extent then reasonably estimable, of the amount of Damages that would reasonably be expected to be suffered or incurred and (v) in
the case of a third party Claim, in addition to the foregoing, the amount or estimated amount of damages (including any Damages) sought thereunder by such Person, any other remedy sought by such Person, any relevant time

  
 38 

 
constraints relating thereto and, to the extent practicable, any other material details pertaining thereto). 
 (b) In the case of a Claim asserted by a Person not a party hereto (including a Claim that may be asserted by a Governmental Authority), the Indemnifying Party may, but shall not be required to, elect to
exercise full control of the defense, compromise or settlement of any such third party Claim by, within 20 Business Days (or such greater time as may be reasonable) of receiving the Claim Notice concerning such indemnity claim, delivering written
notice to such Indemnified Party of the Indemnifying Party’s intention to assume the defense thereof. If the Indemnifying Party does not elect to assume the defense thereof, then the Indemnified Party may retain one counsel, and one local
counsel, if necessary for the effective defense of the Claim (each reasonably satisfactory to the Indemnifying Party), and assume control of the defense of such Claim. 
 (c) If the Indemnifying Party so assumes the defense of any such Claim in accordance herewith, then such Indemnified Party shall cooperate with the Indemnifying Party in any manner that the Indemnifying
Party reasonably may request in connection with the defense, compromise or settlement thereof. If the Indemnifying Party so assumes the defense of any such Claim, the Indemnified Party shall have the right to employ separate counsel and to
participate in (but not control in any manner) the defense, compromise or settlement thereof, but the fees and expenses of such counsel shall be at the sole expense of such Indemnified Party unless (i) the Indemnifying Party has agreed to pay
such fees and expenses, or (ii) such Indemnified Party shall have been advised by its regular outside counsel that a conflict of interest between the Indemnifying Party and the Indemnified Party in the conduct of the defense of such action
would reasonably be expected (in which case the Indemnifying Party shall not have the right to control the defense, compromise or settlement of such action on behalf of the Indemnified Party), and in any such case described in clauses (i) or
(ii) the reasonable fees and expenses of one counsel, and one local counsel, if necessary for the effective defense of the Claim (each reasonably satisfactory to the Indemnifying Party) for all Indemnified Parties shall be borne by the
Indemnifying Party. 
 (d) No Indemnified Party shall settle or compromise or consent to entry of any judgment with respect to
any such action for which it is entitled to indemnification hereunder without the prior consent of the Indemnifying Party. The Indemnifying Party shall not, without the consent of such Indemnified Party, settle or compromise or consent to entry of
any judgment with respect to any such Claim (i) in which any relief other than the payment of money damages is or may be sought against such Indemnified Party (other than a relief seeking rescission of this Agreement) or (ii) that does not
include as an unconditional term thereof the giving to such Indemnified Party by the claimant, the party conducting such investigation, plaintiff or petitioner of a release from all liability with respect to such Claim. 

(e) The Indemnified Party and the Indemnifying Party shall use commercially reasonable efforts to avoid production of confidential
information (consistent with applicable Law), and to cause all communications among employees, counsel and others representing any party to a third party Claim to be made so as to preserve any applicable attorney-client or work-product privileges.

  
 39 

 Section 8.04. Exclusivity. Following the Closing, except in the case of
(a) common law fraud and (b) with respect to matters for which the remedy of specific performance, injunctive relief or other non-monetary equitable remedies are available, the sole and exclusive remedy of the parties with respect to any
and all claims arising from any breach of this Agreement or any of the other matters addressed in Section 8.02 (other than matters relating to the Stockholders Agreement) shall be pursuant to the indemnification provisions set forth in
this Article VIII. 
 Section 8.05. Additional Limitations and Adjustments. 

(a) In the event of any Damage in respect of which an Indemnified Party asserts an indemnification claim, the Indemnified Party shall take
commercially reasonable measures to mitigate the consequences of such Damage. 
 (b) No Indemnified Party shall be entitled to
any indemnification hereunder to the extent that such indemnification would constitute a duplicative payment for the same Damage. 
 (c) Any indemnity payment due and payable by the Indemnifying Party under this Agreement shall be net of (and, for the avoidance of doubt, reduced, whether retroactively or otherwise by) any and all
insurance proceeds and recoveries in respect of indemnification obligations actually received by the Indemnified Party or Affiliate thereof in respect of such Damages, whether such proceeds are received before or after indemnity payments are made;
provided that such proceeds and recovery will be determined net of the reasonable, out-of-pocket costs and expenses incurred in connection with or otherwise related to prosecuting the claims necessary to obtain such proceeds and recovery.

 (d) Without limiting the foregoing, if any Indemnified Party receives from any Person any amounts in respect of Damages
previously paid by the Indemnifying Party or obtains any judgment or award in any litigation relating to such Damages previously paid by the Indemnifying Party, such Indemnified Party shall promptly distribute to the Indemnifying Party all such
amounts received, net of all reasonable, out-of-pocket costs and expenses (including reasonable legal fees and expenses) incurred in connection with obtaining such amounts, judgments or awards, up to the amount of the payment that the Indemnifying
Party had made to the Indemnified Party with respect to such Damages. 
 (e) If an Indemnified Party receives payment from an
Indemnifying Party in respect of any Damages, and the Indemnified Party could have recovered all or a part of such Damages from a third party (a “Potential Contributor”) based on the underlying claim or demand asserted against such
Indemnifying Party, such Indemnified Party shall, to the extent permitted by applicable Law, assign such of its rights to proceed against the Potential Contributor as are necessary or desirable to permit such Indemnifying Party to recover from the
Potential Contributor the amount of such payment. 
 (f) An insurer who would otherwise be obligated to pay any claim shall not
be relieved of the responsibility with respect thereto or, solely by virtue of the indemnification provisions hereof, have any subrogation rights with respect thereto, it being expressly understood

  
 40 

 
and agreed that no insurer or any other third party shall be entitled to a “wind-fall” (i.e., a benefit they would not be entitled to receive in the absence of the
indemnification provisions) by virtue of the indemnification provisions hereof. 
 (g) No claim may be asserted under this
Article VIII (i) by Investor (or any Investor Indemnitee) against the Company if Investor (or any Investor Indemnitee) had knowledge, on or before the Closing, of any fact, event, circumstance or condition giving rise to such claim; or
(ii) by the Company (or any Company Indemnitee) against Investor if the Company (or any Company Indemnitee) had knowledge, on or before the Closing, of any fact, event, circumstance or condition giving rise to such claim.

competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or

possible; provided, however, that in the absence of an agreement as to how to modify this Agreement, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or
circumstances will be interpreted so as reasonably to effect the intent of the parties hereto, and such invalid, void or unenforceable provision of this Agreement shall be replaced with a valid and enforceable provision that will achieve, to the
fullest extent possible, the economic, business and other purposes of such severed provision. 
 Section 9.15. No

CORPORATE GOVERNANCE 
 Section 2.01. Voting Generally. When any action is required to be taken by a Stockholder pursuant to this Agreement, the Certificate of Incorporation or the Bylaws, such Stockholder agrees to take
all steps reasonably necessary to implement such action, including voting at any meeting of stockholders all shares of Equity Securities Beneficially Owned by such Stockholder in favor of such action and/or executing or causing to be executed, as
promptly as practicable, a consent in writing to the taking of such action. Any agreement by a Stockholder to vote all Equity Securities Beneficially Owned by such Stockholder in a certain manner shall be deemed, in each instance, to include an
agreement by such Stockholder to use its commercially reasonable efforts to take all actions necessary to call, or to cause the Company and the appropriate officers and directors of the Company to call, as promptly as practicable, a special or

 -8-

 
circulated among the stockholders of the Company (and to execute and deliver any such consent to such action). Except as expressly provided herein, any provision in this Agreement, the
Certificate of Incorporation or the Bylaws requiring a Stockholder to cause the Board of Directors to take any action shall require such Stockholder (i) to instruct each of its Stockholder Designees to vote in favor of such action or to consent
in writing to the taking of such action and (ii) to take such other actions (including the removal and replacement of its Stockholder Designees) as may be reasonably necessary to cause such action to be taken.

(b) Each Stockholder agrees to vote, or cause to be voted, all Equity Securities Beneficially Owned by such Stockholder from time to time

shall be elected to the Board of Directors: 
 (i) for so long as Liberty continues to Beneficially Own at least
five percent of the Company’s outstanding Common Stock (as adjusted for stock splits, dividends, recapitalizations and the like), at least one individual designated by Liberty (who shall be reasonably acceptable to the Company), which
individual shall initially be Diana Walters; provided, however, that, for so long as Liberty continues to Beneficially Own at least five percent of the Company’s outstanding Common Stock (as adjusted for stock splits, dividends,
recapitalizations and the like), in the event there are more than nine members of the Board of Directors, Liberty shall be entitled to designate one or more additional directors (who shall be reasonably acceptable to the Company), if necessary, in
order to ensure that the percentage of Liberty designees serving on the Board of Directors most closely approximates the percentage of ownership of the Company’s outstanding Common Stock (as adjusted for stock splits, dividends,
recapitalizations and the like) that Liberty Beneficially Owns at such time; and 
 (ii) the remainder of the
Board of Directors shall be designated by the Electrum Group Holders.

Stockholder with the right to designate a director as specified in Section 2.02(b), the director previously designated by such Stockholder and then serving shall be reelected if still eligible to serve as provided in this Agreement.

time to time and at all times, in whatever manner as shall be necessary to ensure that:

Section 2.02(c) may be removed from office unless (A) such removal is directed or approved by the affirmative vote of the Stockholder entitled under Section 2.02(b) to designate such director or (B) the Stockholder
originally entitled to designate or approve such director pursuant to Section 2.02(b) is no longer so entitled to designate or approve such director; 

(ii) any vacancies created by the resignation, removal or death of a director elected pursuant to
Section 2.02(b) or Section 2.02(c) shall be filled pursuant to the provisions of this Section 2; and 
 (iii) upon the request of any Stockholder entitled to designate a director as provided in Section 2.02(b) to remove such director, such director shall be removed. 

(e) If Liberty loses the right to designate a director pursuant to Section 2.02(b)(i), Liberty shall cause its Stockholder
Designee to resign from the Board of Directors and shall take such action (including to vote, or cause to be voted, all Equity Securities Beneficially Owned by Liberty and its Affiliates from time to time and at all times in whatever manner) as
shall be necessary to remove its Stockholder Designee from the Board of Directors. 
 (f) No Stockholder, nor any Affiliate of
any Stockholder, shall have any liability as a result of designating a Person for election as a director for any act or omission by such designated person in such Person’s capacity as a director of the Company, nor shall any Stockholder have

Securities Beneficially Owned by Liberty as of the consummation of such transaction; or (ii) sell, or agree to sell, all or substantially all of the assets or capital stock of any Material Subsidiary (a “Material Subsidiary

or any Material Subsidiary, other than any such transaction (i) with a Public Company (or a Subsidiary of a Public Company, if in connection with such merger, consolidation or other combination, Liberty receives capital stock of such Public
Company), (ii) (A) in which the Equity Securities of the Company are exchanged for cash pursuant to which Liberty will receive a pre-tax amount (plus any Premium Excess Amount) greater than or equal to the Liberty Minimum Return with

Section 5.06(c) of the Purchase Agreement) shall not exceed ten percent of the Company’s outstanding Common Stock as of the date hereof (as adjusted for stock splits, dividends, recapitalizations and the like)) at a per share price less
than the per share purchase price (as adjusted for stock splits, dividends, recapitalizations and the like) paid by Liberty to the Company under the Purchase Agreement for the Initial Liberty Securities, it being understood that any issuances of
such shares or securities in connection with a joint venture, an acquisition (including by way of merger, consolidation or binding share exchange) or similar transaction by the Company of the capital stock, other equity interests or assets of
another Person in a transaction pursuant to which all or part of the consideration payable in connection with such acquisition consists of securities of the Company, including Rights to acquire securities of the Company, the per share purchase price

in the aggregate by all of the Electrum Parties and the total number of Liberty Securities then Beneficially Owned by Liberty. The number of Electrum Securities to be Transferred by such Electrum Party shall be reduced by the number of Liberty
Securities to be Transferred by Liberty in connection with its exercise of its Tag-Along Right. 
 (c) The terms on which the
Electrum Party required to deliver an Electrum Transfer Notice actually Transfers its shares of Electrum Securities shall not be more favorable, and shall include no more cash or other consideration, than the terms on which Liberty Transfers its
shares of Liberty Securities. Liberty shall be required to make the same representations, warranties, covenants and agreements as are given by such Electrum Party in connection with any Transfer pursuant to this Section 3.03 (other than
any such actions which can reasonably be taken only by such Electrum Party). 
 (d) If Liberty exercises its Tag-Along Right,
the Electrum Party required to deliver an Electrum Transfer Notice shall cause the documents relating to the Transfer of its 

  
 -13-

 
shares of Electrum Securities to the proposed transferee to be amended so that such documents include Liberty as a party, and so as to provide that the proposed transferee shall acquire from
Liberty the number of shares of Liberty Securities Beneficially Owned by Liberty as to which the Tag-Along Right has been exercised. The closing of the sale of Liberty Securities by Liberty pursuant to this Section 3.03 shall, to the
extent legally practicable, take place at the same time and place as the closing of the Transfer by such Electrum Party giving rise to the Tag-Along Right. At such closing, (i) Liberty shall deliver to the transferee certificates representing
the Liberty Securities subject to the Transfer, free and clear of any Lien or Restriction other than those created by this Agreement or the transferee; (ii) the transferee shall deliver to Liberty the consideration to be paid for such Liberty
Securities in accordance with the terms of the purchase and sale of such Liberty Securities and of the Electrum Securities of such Electrum Party; and (iii) Liberty shall execute such other documents and take such other actions as are
reasonably necessary to consummate the sale of such Liberty Securities and are also being taken by such Electrum Party (other than any such actions as can reasonably be taken only by such Electrum Party). 

(e) In the event Liberty fails to exercise its Tag-Along Rights within the Tag-Along Exercise Period or, if so exercised, Liberty is
unable to consummate such transaction within 10 Business Days after the closing of the sale of the Electrum Securities because of its failure to obtain any required Governmental Approval or other consent or its failure to comply with its covenants
and agreements as required by Section 3.03(c) (including its ability to deliver the applicable Liberty Securities free and clear of all Liens or Restrictions), such Electrum Party shall thereafter be entitled during the period of 60
Business Days following the conclusion of the applicable period to Transfer the Electrum Securities at a price and upon terms no more favorable to the purchasers of such Electrum Securities than were specified in the Electrum Transfer Notice.
Notwithstanding the foregoing, if such Transfer is subject to the receipt of any Governmental Approval, the time period during which such Transfer may be consummated shall be extended until the expiration of five Business Days after all such
Governmental Approvals or other consents have been obtained, but in no event shall such time period exceed 120 Business Days following the conclusion of the applicable period. In the event the Electrum Party has not Transferred the Electrum
Securities within such 60 Business Day period or, if applicable, 120 Business Day period, such Electrum Party shall not thereafter Transfer such Electrum Securities unless such Electrum Party again complies in full with the provisions of this
Section 3.03. 
 (f) Any purported Transfer of Electrum Securities in violation of this Section 3.03
shall be void and ineffective as against both the Electrum Party required to deliver an Electrum Transfer Notice and the proposed transferee. 
 Section 3.04. Electrum Group Holders Right of First Offer. 
 (a) For so long
as Liberty continues to Beneficially Own at least five percent of the Company’s outstanding Common Stock (as adjusted for stock splits, dividends, recapitalizations and the like), neither Liberty nor any Liberty Permitted Transferee shall
Transfer any Liberty Securities to a Person (other than to Liberty or a Liberty Permitted Transferee or pursuant to Section 3.03 or Section 3.05), unless prior to such Transfer, Liberty first delivers a notice (a
“Liberty Transfer Notice”) to the Electrum Group Holders, setting forth (i) the number of shares of Liberty Securities that Liberty or any Liberty Permitted 

  
 -14-

 
Transferee wishes to Transfer, (ii) the minimum price per share of Liberty Securities at which such shares of Liberty Securities are proposed to be Transferred and (iii) any other terms
of the proposed Transfer; provided, however, that neither Liberty nor any Liberty Permitted Transferee may Transfer any Liberty Securities to a Person (other than to Liberty or a Liberty Permitted Transferee or pursuant to
Section 3.03 or Section 3.05) for a period of three months following the date of this Agreement. 
 (b)
The Electrum Group Holders, as a group, or their designee(s) shall have the right (the “Right of First Offer”), exercisable by written notice delivered to Liberty not later than 10 Business Days following the date the Liberty
Transfer Notice is given (the “Right of First Offer Exercise Period”), to elect to purchase all or any portion of the Liberty Securities being offered, on the terms set forth in the Liberty Transfer Notice, for cash consideration
equal to the product of (i) the number of Liberty Securities sought to be Transferred by Liberty as set forth in the Liberty Transfer Notice and (ii) the minimum price per share of the Liberty Securities as set forth in the Liberty
Transfer Notice (the “Minimum Price”). 
 (c) If any Electrum Group Holder or its designee exercises its Right
of First Offer, the closing of the purchase of the Liberty Securities with respect to which such Right of First Offer has been exercised shall take place within 30 Business Days after the giving of notice of such exercise, which period of time shall
be extended for a maximum of 60 Business Days in order to comply with applicable Laws. Each of the Company, any Electrum Group Holder which has agreed to purchase the Liberty Securities and/or any designee of an Electrum Group Holder agrees to use
its commercially reasonable efforts to secure any Governmental Approvals or other consents, and to comply with any Law necessary, in connection with the Transfer of such Liberty Securities. 

(d) In the event any Electrum Group Holder or its designee fails to exercise its Right of First Offer within the Right of First Offer
Exercise Period or, if so exercised, such Electrum Group Holder is unable to consummate such purchase within the time period specified in Section 3.04(c) because of its failure to obtain any required Governmental Approval or other
consents, Liberty shall thereafter be entitled, during the period of 30 Business Days following the conclusion of the applicable period, to Transfer all, but not less than all, of the Liberty Securities not purchased pursuant to this
Section 3.04 or which such electing Electrum Group Holder or its designee is unable to purchase because of such failure to obtain any such Governmental Approval or other consents, to any Person (other than to a competitor of the Company,
as determined by the Board of Directors in good faith), on terms no better than the terms set forth in the Liberty Transfer Notice and for cash not less than the Minimum Price. Notwithstanding the foregoing, if such Transfer is subject to the
receipt of any Governmental Approval, the time period during which such Transfer may be consummated shall be extended until the expiration of five Business Days after all such Governmental Approvals have been obtained, but in no event shall such
time period exceed 60 Business Days from following the conclusion of the applicable period. In the event Liberty has not Transferred the Liberty Securities within such 30 Business Day period or, if applicable, 60 Business Day period, Liberty shall
not thereafter Transfer such Liberty Securities unless Liberty again complies in full with the provisions of this Section 3.04. 
 (e) Any purported Transfer of Liberty Securities in violation of this Section 3.04 shall be void and ineffective as against both Liberty and the proposed transferee. 

  
 -15-

 Section 3.05. Drag-Along Rights. 

(a) If the Electrum Parties approve a Qualifying Sale, then the Electrum Parties may deliver a notice (a “Drag-Along
Notice”) to Liberty setting forth (i) the number of shares of Equity Securities proposed to be Transferred in such Qualifying Sale, (ii) the price per share at which the shares of Equity Securities are proposed to be Transferred
in such Qualifying Sale, (iii) all Liens and Restrictions to which the shares of Equity Securities proposed to be Transferred in such Qualifying Sale will be subject, (iv) whether the Equity Securities proposed to be Transferred in such
Qualifying Sale are to be Transferred for cash or other consideration and (v) the other material terms of the proposed Qualifying Sale. 
 (b) Upon receipt of a Drag-Along Notice, Liberty shall be required: 
 (i) if such Qualifying Sale requires Stockholder approval, to vote all Liberty Securities in favor of, and adopt, such Qualifying Sale and to vote in opposition to any and all other proposals that could
reasonably be expected to delay or impair the ability of the Company or the Electrum Parties to consummate such Qualifying Sale; 
 (ii) subject to Section 3.05(c), to execute and deliver all related documentation and to take such action in support of the Qualifying Sale as reasonably requested by the Company and the
Electrum Parties in order to carry out the terms of this Section 3.05, including executing and delivering instruments of conveyance and Transfer, share certificates duly endorsed for Transfer (free and clear of any impermissible Liens or
Restrictions), any purchase, merger or similar Contract, consent, waiver or documents necessary in connection with the receipt of a Governmental Approval, and any similar or related documents; 

(iii) not to deposit, and to cause its Affiliates not to deposit, any Liberty Securities in a voting trust or subject any
Liberty Securities to any arrangement with respect to the voting of such Liberty Securities, unless specifically requested to do so by the proposed acquirer in connection with such Qualifying Sale; 

(iv) to refrain from exercising any dissenters’ rights or rights of appraisal under applicable Law at any time with
respect to such Qualifying Sale; and 
 (v) to Transfer to the proposed transferee, as applicable, (A) all
shares of Liberty Securities then Beneficially Owned by Liberty or (B) in the event of a Stock Sale, the (1) number of shares of Liberty Securities then Beneficially Owned by Liberty multiplied by (2) a fraction, (I) the
numerator of which is the number of shares of Electrum Securities proposed to be Transferred by the Electrum Parties as set forth in the Drag-Along Notice and (II) the denominator of which is the number of shares of Electrum Securities then
Beneficially Owned in the aggregate by the Electrum Parties. 
 (c) Upon exercise by the Electrum Parties of Drag-Along Rights,
the terms on which Liberty actually Transfers Liberty Securities in connection with such Qualifying Sale shall not be less favorable, and shall not include less cash, than the terms on which the Electrum Parties Transfer their Electrum Securities.
Liberty shall be required to make the same representations, warranties, covenants and agreements as are given by the Electrum Parties in 

  
 -16-

 
connection with such Qualifying Sale pursuant to this Section 3.05 (other than any such action which can reasonably be taken only by the Electrum Parties). 

(d) If the Electrum Parties exercise their Drag-Along Right, the Electrum Parties shall cause the documents relating to the Qualifying
Sale to include Liberty as a Transferring party. The closing of the Transfer of any Liberty Securities by Liberty in connection with a Qualifying Sale shall, to the extent legally practicable, take place at the same time and place as the closing of
the Transfer of Electrum Securities by the Electrum Parties in connection with such Qualifying Sale. At such closing, (i) Liberty shall deliver to the transferee certificates representing the Liberty Securities subject to the Transfer, free and
clear of any Lien or Restriction other than those created by this Agreement or the transferee; (ii) the transferee shall deliver to Liberty the consideration to be paid for the applicable Liberty Securities in accordance with the terms of the
purchase and sale of such Liberty Securities and of the Electrum Securities; and (iii) Liberty shall execute such other documents and take such other actions as are reasonably necessary to consummate the sale of such Liberty Securities and are
also being taken by the Electrum Parties (other than any such actions as can reasonably be taken only by the Electrum Parties) in connection with such Qualifying Sale. 
 Section 3.06. Lock-Up. 
 (a) Liberty and each Electrum Group Holder hereby
agrees that, if required by the managing underwriter, it will not, during the period commencing on the date of the final prospectus relating to the Company’s initial public offering (the “IPO”) and ending on the date specified
by the Company and the managing underwriter (such period not to exceed l80 days, which period may be extended upon the request of the managing underwriter for an additional period of up to 15 days if the Company issues or proposes to issue an
earnings or other public release within 15 days of the expiration of the 180 day lock-up period), lend, offer, pledge, Contract to sell, sell any option or Contract to Transfer, purchase any option or Contract to sell, grant any option, right
or warrant to purchase, or otherwise Transfer, directly or indirectly, any shares of Equity Securities Beneficially Owned immediately before the effective date of the registration statement for such offering. The foregoing provisions of this
Section 3.06 shall not apply to the sale of any Equity Securities to an underwriter pursuant to an underwriting agreement and shall only be applicable to Liberty and the Electrum Group Holders if all officers, directors and stockholders
of more than five percent of the Company’s outstanding Equity Securities are subject to the same restrictions. The underwriters in connection with such registration are intended third party beneficiaries of this Section 3.06 and
shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 
 (b) Liberty
further agrees (i) to execute such agreements as may be reasonably requested by the Company or the underwriters in connection with such registration that are consistent with this Section 3.06 or that are necessary to give further
effect thereto; and (ii) if requested by the Company or the underwriters to use its commercially reasonable efforts to provide, within five Business Days of such request, such information as may be required by the Company or the underwriters in
connection with the completion of the IPO. 
 (c) In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the shares of Equity Securities Beneficially Owned by 

  
 -17-

 
Liberty and the Electrum Group Holders (and transferees and assignees thereof) until the end of such restricted period. 
 ARTICLE IV 
 ADDITIONAL AGREEMENTS 

Section 4.01. Preemptive Rights. 
 (a) If the Company proposes to offer New Securities, the Company shall first deliver a notice (the “New Securities Notice”) to Liberty, setting forth (i) the New Securities to be
offered, (ii) the price per share of the New Securities proposed to be offered, (iii) all Liens and Restrictions to which the shares of New Securities proposed to be offered will be subject, (iv) whether the shares of New Securities
proposed to be offered are to be offered for cash or other consideration and (v) the other terms of the proposed offer. 

(b) For so long as Liberty continues to Beneficially Own at least 10 percent of the Company’s outstanding Common Stock (as adjusted
for stock splits, dividends, recapitalizations and the like), Liberty shall have the right (“Preemptive Right”), exercisable by written notice delivered to the Company not later than 10 Business Days following the date the New
Securities Notice is given (the “Preemptive Right Exercise Period”), to elect to purchase up to an aggregate number of shares of New Securities (or in the case of Rights, the total number or such shares covered by Rights) equal to
the number determined by multiplying (i) the number of New Securities proposed to be offered by (ii) a fraction, (A) the numerator of which is the number of shares of Equity Securities then Beneficially Owned by Liberty and
(B) the denominator of which is the number of Equity Securities then outstanding; provided, however, that for purposes of determining the number of shares of Equity Securities outstanding, such amount shall include, without
duplication, shares of Equity Securities issuable upon the conversion of outstanding convertible equity securities of the Company and shares of Equity Securities issuable upon the exercise of outstanding options or warrants to purchase Equity
Securities. Such notice shall constitute an agreement of Liberty to purchase the amount of New Securities so specified upon the price and other terms set forth in the New Securities Notice. The number of New Securities to be offered by the Company
shall be reduced by the number of New Securities to be purchased by Liberty in connection with its exercise of Preemptive Rights. 
 (c) If Liberty exercises its Preemptive Right, the closing of the purchase of the New Securities with respect to which such Preemptive Right has been exercised shall take place within 30 Business Days
after the giving of notice of such exercise, which period of time shall be extended for a maximum of 120 Business Days in order to comply with applicable Laws. Each of the Company and Liberty agrees to use its commercially reasonable efforts to
secure any Governmental Approvals or other consents, and to comply with any Law necessary in connection with the offer, sale and purchase of, such New Securities. 
 (d) In the event Liberty fails to exercise its Preemptive Right within the Preemptive Right Exercise Period or, if so exercised, Liberty is unable to consummate such purchase within the time period
specified in Section 4.01(c) because of its failure to obtain any 

  
 -18-

 
required Governmental Approval or other consent, the Company shall thereafter be entitled during the period of 60 Business Days following the conclusion of the applicable period to offer the New
Securities or Rights not elected to be purchased pursuant to this Section 4.01 or which Liberty is unable to purchase because of such failure to obtain any such Governmental Approval or other consent, at a price and upon terms no more
favorable to the purchasers of such New Securities than were specified in the New Securities Notice. Notwithstanding the foregoing, if such sale is subject to the receipt of any Governmental Approval, the time period during which such sale may be
consummated shall be extended until the expiration of five Business Days after all such Governmental Approvals have been obtained, but in no event shall such time period exceed 120 Business Days following the conclusion of the applicable period. In
the event the Company has not sold the New Securities within such 60 Business Day period or, if applicable, 120 Business Day period, the Company shall not thereafter offer, issue or sell such New Securities unless the Company again complies in full
with the provisions of this Section 4.01. 
 (e) Any purported offer of New Securities in violation of this
Section 4.01 shall be void and ineffective against both the Company and the proposed transferee. Notwithstanding the foregoing, Liberty shall not be entitled to any Preemptive Rights in respect of the issuance of shares of New Securities
issued to satisfy Rights theretofore issued and as to which Liberty theretofore had the opportunity to exercise Preemptive Rights pursuant to this Section 4.01. 
 Section 4.02. Financial Statements. For so long as Liberty continues to Beneficially Own shares of the Company’s Common Stock, the Company shall deliver to Liberty: 

(a) as soon as practicable, an audited balance sheet of the Company as of the end of such fiscal year and audited statements of income and
of cash flows of the Company for such fiscal year, in each case, certified by certified public accountants selected by the Company and approved by the Board of Directors and prepared in accordance with GAAP or IFRS; and 

(b) as soon as practicable, an unaudited balance sheet of the Company as of the end of the first three fiscal quarters and unaudited
statements of income and of cash flows of the Company for such fiscal quarters and for the current fiscal year to the end of such fiscal quarter, in each case, prepared in accordance with GAAP or IFRS. 

The foregoing financial statements shall be prepared on a consolidated basis of the Company and each Subsidiary of the Company. 

Section 4.03. Confidentiality. 
 (a) Each Stockholder agrees that such Stockholder shall keep confidential and shall not disclose, divulge or use, and shall cause its Affiliates, trustees, directors, employees, accountants, attorneys,
agents, representatives and advisors (collectively, “Representatives”) to keep confidential and not disclose, divulge or use, for any purpose, other than to monitor its investment in the Company, any Confidential Information, unless
such Confidential Information (a) is known or becomes known to the public in general (other than as a result of a breach of this Section 4.03 by such Stockholder or its Representatives), (b) is or has been independently

  
 -19-

 
developed or conceived by such Stockholder without use of the Company’s Confidential Information or (c) is or has been made known or disclosed to such Stockholder by a third Person
without a breach of any obligation of confidentiality such third Person may have to the Company or any other Person; provided, however, that a Stockholder may disclose Confidential Information (i) to such Stockholder’s
Representatives to the extent necessary to obtain their services in connection with monitoring its investment in the Company, (ii) to any prospective purchaser of any Equity Securities from such Stockholder, provided that such prospective
purchaser agrees to be bound in writing by the provisions of this Section 4.03, (iii) to any Affiliate or Permitted Transferee of such Stockholder, provided that such Stockholder informs such Affiliate or Permitted Transferee that
such information is confidential and directs such Affiliate to maintain the confidentiality of such information or (iv) as may otherwise be required by Law, provided that such Stockholder shall promptly notify the Company in writing of such
requirement and cooperate with the Company to preserve the confidentiality of such information consistent with applicable Law. Each Stockholder shall be responsible for any disclosure or use of the Confidential Information by it or its
Representatives in a manner inconsistent with this Agreement. 
 (b) For so long as Liberty or its Affiliates hold Equity
Securities of the Company, neither Liberty nor its Affiliates shall acquire, directly or indirectly, any present or future right, title or interest in any real property interest or mining rights within two kilometers of the current external
boundaries of the properties of the Company. If Liberty or its Affiliates acquire any such right or interest in violation of the foregoing, Liberty or its applicable Affiliate shall immediately notify the Company and shall offer to transfer all of
its right, title and interest therein to the Company without any payment or reimbursement by the Company other than Liberty’s or its Affiliate’s costs and expenses related to such purchase. Notwithstanding the above, the foregoing
prohibition shall not apply to (i) any entity in which Liberty or its Affiliates invest, provided that (A) Liberty or its Affiliates do not actively manage or maintain a Controlling interest, and (B) such entity does not receive any
information from Liberty or its Affiliates in violation of this Agreement, and (ii) unsolicited offers to Liberty or its Affiliates by a third party without any violation of the provisions of this Agreement and in the normal course of Liberty
or its Affiliates reviewing prospect proposals.

substantially the same as the following legend:

STOCKHOLDERS AGREEMENT. 
 The Company, by its execution of this Agreement, agrees that it will cause the certificates evidencing such Equity
Securities issued after the date hereof to bear the legend required by this Article V; provided, however, that the parties agree that the failure of the Company to cause the certificates evidencing such Equity Securities to bear
the legend required by this Article V shall not affect the validity or enforcement of this Agreement.

with this Section 8.06; provided, however, that, with respect to the foregoing, (i) any such proceeding shall be brought exclusively in the state courts in the State of New York located in New York, New York or in the
federal courts located in the State of New York; and (ii) each party consents to personal jurisdiction in such proceeding in any such court (and of the appropriate appellate courts therefrom) and irrevocably waives, to the fullest extent
permitted by Law, any objection that it may now have to the laying of the venue of any such proceeding in any such court or that any such proceeding brought in any such court has been brought in an inconvenient forum. 

Section 8.07. Specific Performance. The parties agree that irreparable damage would occur if any provision of this Agreement were
not performed in accordance with the terms hereof and that Company or any Stockholder will be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions
hereof, in addition to any other remedy

to which it may be entitled at Law or in equity, without the necessity of posting or securing any bond with respect thereto. 

Section 8.08. Counterparts; Effectiveness. This Agreement may be executed in two or more counterparts, all of which shall be
considered the same agreement. Signature pages from separate identical counterparts may be combined with the same effect as if the parties signing such signature page had signed the same counterpart. This Agreement shall become effective when each
party hereto shall have received counterparts hereof signed by all of the other parties hereto. 
 Section 8.09.
Captions. The table of contents and captions herein are included for convenience of reference only and shall be ignored in the construction or interpretation hereof. 
 Section 8.10. Entire Agreement. This Agreement (including the Schedules attached hereto or delivered in connection herewith) and the Purchase Agreement constitute the entire agreement among the
parties hereto with respect to the matters covered hereby and thereby, and all written or oral agreements, representations, warranties or covenants previously existing between the parties with respect to such subject matter are cancelled and are not
part of this Agreement or the Purchase Agreement. 
 Section 8.11. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and
effect. Upon such determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner; provided, however, that in the
absence of an agreement as to how to modify this Agreement, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect
the intent of the parties hereto, and such invalid, void or unenforceable provision of this Agreement shall be replaced with a valid and enforceable provision that will achieve, to the fullest extent possible, the economic, business and other
purposes of such severed provision. 
 Section 8.12. No Strict Construction. Each party acknowledges that this Agreement
has been prepared jointly by the parties hereto and shall not be strictly construed against any party hereto. 
 Section 8.13.
