 (b) Adjustment Definitions. 

(i) “Adjustment Amount” means a net positive or negative number, and is computed as the sum of the following: 

 

	 	(A)	the amount of Working Capital of the Company computed by reference to the Company Balance Sheet on the Adjustment Date, less $950,000; plus 

 

	 	(B)	the amount of Other Net Assets of the Company computed by reference to the Company Balance Sheet on the Adjustment Date, less $719,805. 

For illustrative purposes only, if the transactions contemplated herein had closed on June 30, 2014, the Adjustment Amount would have been calculated in
accordance with the Estimated Closing Payment Statement attached hereto as Schedule 2.02(c). 
 (ii) “Adjustment
Date” means the last day of the month prior to the Closing Date, and the Adjustment Amount will be calculated utilizing the accounting data of the Company as of the Adjustment Date. For illustrative purposes only, if the Closing Date

 (c) Closing Adjustment. 

(i) At least fifteen (15) Business Days before the Closing, EWI will prepare and deliver to Buyer a statement setting forth its
good faith estimate of the Purchase Price, based on EWI’s good faith estimate of the Adjustment Amount (the “Estimated Closing Payment Statement”), which statement will contain an estimated Company Balance Sheet as of the
Adjustment Date (without giving effect to the transactions contemplated herein) and calculations of Working Capital and Other Net Assets as of the Adjustment Date. For illustrative purposes only, a sample Estimated Closing Payment Statement is
attached hereto as Schedule 2.2(c), as if the transactions contemplated herein had closed on June 30, 2014. 
 (ii)
Within ten (10) Business Days following receipt by Buyer of the Estimated Closing Payment Statement, Buyer may object in good faith and in writing to any amount, or calculation set forth therein. If Buyer objects to the Estimated Closing
Payment Statement, the Parties will attempt to reconcile such difference in good faith. If the Parties are unable to reconcile such differences within five (5) Business Days following receipt by EWI of Buyer’s objections, or if Buyer does
not dispute the Estimated Closing Payment Statement, the Base Purchase Price will be adjusted for purposes of the Closing by the amount of the estimated Adjustment Amount not in dispute (as adjusted, the “Closing Payment Amount”).
Specifically, if the Adjustment Amount is a positive number, the base Purchase Price will be increased by such amount; and if the Adjustment Amount is a negative number, the base Purchase Price will be decreased by such amount. 

(d) Post-Closing Adjustment. 

(i) Within sixty (60) days after the Closing Date, Buyer will prepare and deliver to EWI a statement (the “Post-Closing
Adjustment Statement”) that reflects Buyer’s determination of (A) the Adjustment Amount and (B) the Purchase Price based on the Adjustment Amount. In addition, Buyer will provide EWI with supporting calculations, in
reasonable detail, for such determinations at the time it delivers the Post-Closing Adjustment Statement. EWI agrees to cooperate with Buyer in connection with Buyer’s preparation of the Post-Closing Adjustment Statement and related
information, and will provide Buyer with such access to its books, records, information, and employees as Buyer may reasonably request. 

(ii) The amounts determined by Buyer as set forth in the Post-Closing Adjustment Statement will be final, binding, and conclusive for
all purposes unless, and only to the extent, that within thirty (30) days after Buyer has delivered the Post-Closing Adjustment Statement, EWI notifies Buyer in writing of any dispute with matters set forth in the Post-Closing Adjustment
Statement. Any such notice of dispute delivered by EWI (an “Adjustment Dispute Notice”) will identify each item in the Post-Closing Adjustment Statement with respect  

  
 11 

 
to which EWI disagrees, the basis of such disagreement, and EWI’s position with respect to such disputed item. Buyer agrees to cooperate with EWI in connection with EWI’s preparation of
the Adjustment Dispute Notice and will provide EWI with such access to the Company’s books, records, information and employees as EWI may reasonably request. 

(iii) If EWI delivers an Adjustment Dispute Notice in compliance with Section 2.04(d)(ii), then (A) the undisputed
portion of the total proposed Adjustment Amount set forth in the Post-Closing Adjustment Statement will be paid by the appropriate Party in accordance with the payment procedures set forth in Section 2.02(d)(iv) and (ii) Buyer and
EWI will attempt to reconcile their differences and any resolution by them as to any disputed amounts will be final, binding, and conclusive for all purposes on the Parties. If Buyer and EWI are unable to reach a resolution with respect to all
disputed items within forty-five (45) days of delivery of the Adjustment Dispute Notice, Buyer and EWI will submit any items remaining in dispute for determination and resolution to the Independent Accounting Firm, which will be instructed to
determine and report to the Parties, within thirty (30) days after such submission, upon such remaining disputed items. The report of the Independent Accounting Firm will be final, binding, and conclusive on the Parties for all purposes. The
fees and disbursements of the Independent Accounting Firm will be allocated between Buyer, on the one hand, and EWI, on the other hand, so that Buyer’s share of such fees and disbursements will be in the same proportion that the aggregate
amount of such remaining disputed items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by Buyer (as finally determined by the Independent Accounting Firm) bears to the total amount of such remaining disputed amounts
so submitted to the Independent Accounting Firm and EWI’s share of such fees and disbursements will be the remaining balance. 

(iv) Within five (5) Business Days following the final determination of the Purchase Price pursuant to this
Section 2.02, (A) if the Purchase Price is greater than the Closing Payment Amount and all other amounts paid by Buyer to EWI pursuant to this Section 2.02, Buyer will pay the difference to EWI or (B) if the
Purchase Price is less than the Closing Payment Amount and all other amounts paid by Buyer to EWI pursuant to this Section 2.02, EWI will jointly and severally be liable for and pay the difference to Buyer. Any amount paid under this
Section 2.04(b)(iv) will be paid in cash by wire transfer of immediately available funds to the account specified by the Party receiving payment. 

(e) Adjustments for Tax Purposes. Any payments made pursuant to this Section 2.02 will be treated as an adjustment to
the Purchase Price by the Parties for Tax purposes, unless otherwise required by Law. 
 (f) Allocation of Purchase
Price. The Purchase Price will be allocated among the purchase of the Shares, the Non-Competition Agreement and the Letter Agreement as set forth in Schedule 2.02(f). The Purchase Price allocation for Tax purposes is not governed by
Schedule 2.02(f) and is, instead, governed by Section 6.05(b). 
 Section 2.03 Transactions to be Effected at
Closing. 
 (a) At Closing, EWI will deliver to Buyer stock certificates evidencing the Shares, free and clear of all Encumbrances, duly
endorsed in blank or accompanied by stock powers or other instruments of transfer duly executed in blank, with all required stock transfer tax stamps affixed thereto. 

  
 12 

 (b) At Closing, Buyer will pay EWI the Closing Payment Amount by wire transfer of immediately
available funds to an account of EWI designated in writing by EWI to Buyer no later than two (2) Business Days prior to the Closing Date.

(b) if the date on which the last of the conditions to Closing set forth in Article VII are satisfied or waived is within five days of the end of the month, then the Closing Date will be extended to the first day of the second calendar

any Person to a Tax pursuant to Section 409A of the Code, whether pursuant to the consummation of the transactions contemplated herein or otherwise. No benefit arrangement or Contract of the Company provides a gross-up or other indemnification
for any Taxes that may be imposed for failure to comply with the requirements of Section 409A of the Code.

Section 4999 of the Code, and no amount payable as a result of or in connection with the consummation of the transaction contemplated herein to any employee, consultant or director of the Company who is a “disqualified individual” (as
such term is defined in proposed Treasury Regulation Section 1.280G-1) could be characterized as an “excess parachute payment” (as defined in Section 280G(b)(1) of the Code). There is no benefit arrangement or other Contract by
which the Company is bound to compensate any employee of the Company or other service provider of the Company for excise taxes paid pursuant to Section 4999 of the Code.

material respects. At the Closing, all of those books and records will be in the possession of the Company.

Applicable Financial Principles and to maintain accountability for assets. 
 Section 3.23 Brokers. No broker, finder or

TAX MATTERS 

Section 6.01 Tax Covenants. 

(a) Without the prior written consent of Buyer, EWI (and, prior to the Closing, the Company, its Affiliates and their respective
Representatives) will not, to the extent it may affect, or relate to, the Company, make, change or rescind any Tax election, amend any Tax Return or take any position on any Tax Return, or take any action, omit to take any action or enter into any
other transaction that would have the effect of increasing the Tax liability or reducing any Tax asset of Buyer or the Company in respect of any Post-Closing Tax Period. EWI agrees that Buyer is to have no liability for any Tax resulting from any
action of EWI, the Company on or before the Closing Date, its Affiliates or any of their respective Representatives, and agrees to indemnify and hold harmless Buyer (and, after the Closing Date, the Company) against any such Tax or reduction of any
Tax asset. 
 (b) All transfer, documentary, sales, use, stamp, registration, value added and other such Taxes and fees (including any
penalties and interest) incurred in connection with this Agreement and the other Transaction Documents (including any real property transfer Tax and any other similar Tax) will be borne and paid by EWI when due. EWI will, at its own expense, timely
file any Tax Return or other document with respect to such Taxes or fees (and Buyer will cooperate with respect thereto as necessary). 

  
 40 

 (c) EWI will prepare or cause to be prepared, and file or cause to be filed, all income
Tax Returns required to be filed by or on behalf of the Company for any Pre-Closing Tax Period. Buyer will prepare, or cause to be prepared, all non-income Tax Returns required to be filed by the Company after the Closing Date with respect to a
Pre-Closing Tax Period. Any such Tax Return will be prepared in a manner consistent with past practice (unless otherwise required by Law) and without a change of any election or any accounting method and will be submitted by Buyer to EWI (together
with schedules, statements and, to the extent requested by EWI, supporting documentation) at least forty-five (45) days prior to the due date (including extensions) of such Tax Return. If EWI objects to any item on any such Tax Return, it will,
within ten days after delivery of such Tax Return, notify Buyer in writing that it so objects, specifying with particularity any such item and stating the specific factual or legal basis for any such objection. If a notice of objection will be duly
delivered, Buyer and EWI will negotiate in good faith and use their reasonable best efforts to resolve such items. If Buyer and EWI are unable to reach such agreement within ten days after receipt by Buyer of such notice, the disputed items will be
resolved by a nationally recognized accounting firm selected by Buyer and reasonably acceptable to EWI (the “Accounting Referee”) and any determination by the Accounting Referee will be final. The Accounting Referee will resolve any
disputed items within twenty days of having the item referred to it pursuant to such procedures as it may require. If the Accounting Referee is unable to resolve any disputed items before the due date for such Tax Return, the Tax Return will be
filed as prepared by Buyer and then amended to reflect the Accounting Referee’s resolution. The costs, fees and expenses of the Accounting Referee will be borne equally by Buyer, on the one hand, and EWI, on the other hand. The preparation and
filing of any Tax Return of the Company that does not relate to a Pre-Closing Tax Period will be exclusively within the control of Buyer. 

Section 6.02 Termination of Existing Tax Sharing Agreements. Any and all existing Tax sharing agreements (whether written or not)
binding upon the Company will, as to the Company, be terminated as of the Closing Date. After such date the Company will have no further rights or liabilities thereunder. 

Section 6.03 Tax Indemnification. EWI and EWD, jointly and severally, will indemnify each Buyer Indemnitee and hold them harmless
from and against (a) any Loss attributable to any breach of or inaccuracy in any representation or warranty made in Section 3.20, (b) any Loss attributable to any breach or violation of, or failure to fully perform, any
covenant, agreement, undertaking or obligation in Article VI, (c) all Taxes of the Company or relating to the business of the Company for all Pre-Closing Tax Periods (including any Tax attributable to the making of the
Section 338(h)(10) Election), (d) all Taxes of any member of an affiliated, consolidated, combined or unitary group of which the Company (or any predecessor of the Company) is or was a member on or prior to the Closing Date by reason of a
liability under Treasury Regulation Section 1.1502-6 or any comparable provisions of foreign, state or local Law, and (e) any and all Taxes of any Person imposed on the Company or Buyer arising under the principles of transferee or
successor liability or by contract, relating to an event or transaction occurring before the Closing Date. In each of the above cases, together with any out-of-pocket  

  
 41 

 
fees and expenses (including attorneys’ and accountants’ fees) incurred in connection therewith. EWI will reimburse Buyer for any Taxes that are the responsibility of EWI pursuant
to this Section 6.02 within ten (10) Business Days after payment of such Taxes by Buyer or the Company. 

Section 6.04 Straddle Period. With respect to any taxable period of the Company that would (absent an election) include, but not
end until after, the Closing Date (a “Straddle Period”), Buyer and EWI will, to the extent permitted by applicable Law, elect with the relevant Tax authority to close such Straddle Period as of the close of the Closing Date. In any
case where applicable Law does not permit the Company to close a Straddle Period as of the close of the Closing Date, the portion of any such Taxes that are treated as Pre-Closing Taxes for purposes of this Agreement will be: 

(a) in the case of Taxes based upon, or related to, income or receipts, deemed equal to the amount which would be payable if the taxable year
ended with the Closing Date; and 
 (b) in the case of other Taxes, deemed to be the amount of such Taxes for the entire period multiplied by
a fraction the numerator of which is the number of days in the period ending on the Closing Date and the denominator of which is the number of days in the entire period. 

Section 6.05 Section 338(h)(10) Election. 

(a) Election. 

(i) The Company and EWI will join with Buyer in making a timely election under Section 338(h)(10) of the Code (and any
corresponding election under state, local, and foreign Law) with respect to the purchase and sale of the Shares of the Company hereunder (collectively, a “Section 338(h)(10) Election”). EWI and Buyer acknowledge that for Federal
income Tax purposes (and for state income Tax purposes in those states whose income Tax provisions follow the federal income Tax treatment), the sale of the Shares combined with the Section 338(h)(10) Election will be treated as a sale of
assets by the Company to a wholly-owned Subsidiary of Buyer followed by a complete liquidation of the Company into EWI. EWI and Buyer will report (and will cause their respective Affiliates to report) any transactions that occur under this Agreement
consistent with the Section 338(h)(10) Election, and will take no position (nor allow their respective Affiliates to take a position) contrary thereto or inconsistent therewith unless required to do so by applicable Tax Laws. EWI will pay any
Tax attributable to the making of the Section 338(h)(10) Election and EWI will indemnify Buyer and the Company against any adverse consequences arising out of any failure to pay any such Taxes or any failure by EWI to make a timely
Section 338(h)(10) Election. 
 (ii) For the purpose of making the Section 338(h)(10) Election for federal income Tax
purposes, on the Closing Date, EWI and Buyer will each deliver to the other an executed IRS Form 8023 (or successor form). In addition, EWI and Buyer will each provide to the other all necessary information to permit the Section 338(h)(10)
Election to be made. 

  
 42 

 (b) Allocation of Purchase Price. 

(i) Within ninety (90) days after the Closing Date, Buyer will prepare and provide to EWI a completed IRS Forms 8883 and 8594 (the
“Tax Allocation Statements”) allocating the Purchase Price and liabilities of the Company (and any other relevant items) to the assets of the Company in a manner consistent with applicable treasury regulations. Buyer
and EWI will mutually agree on the items set forth on the Tax Allocation Statements. Buyer and EWI agree to use the Tax Allocation Statements for Tax reporting purposes. Buyer and EWI will file all tax Returns (including amended returns and claims
for refund) and information reports in a manner consistent with the Tax Allocation Statements. Any adjustments to the Purchase Price pursuant to Section 2.02 herein will be allocated in a manner consistent with the Tax Allocation
Statements. 
 (ii) If EWI disagrees with the Tax Allocation Statements, EWI may, within fifteen (15) days after receipt of the Tax
Allocation Statements, deliver written notice to Buyer setting forth the grounds for EWI’s disagreement (an “Objection Notice”). Upon delivery of such Objection Notice to Buyer, EWI and Buyer will negotiate in good faith to
resolve such dispute; provided, however, that if EWI and Buyer are unable to resolve any dispute with respect to the Tax Allocation Statements within twenty (20) days of delivery of such Tax Allocation Statements, such dispute
will be resolved by the Accounting Referee. The fees and expenses of the Accounting Referee will be borne equally by EWI and Buyer. 
 (iii)
EWI and Buyer agree that the Purchase Price and the Liabilities of the Company (plus other relevant items) will be allocated among the assets of the Company for tax purposes as follows: All amounts constituting consideration within the meaning of,
and for the purposes of, Section 1060 of the Code and the regulations thereunder will be allocated among the assets of the Company in the manner required by Section 1060 of the Code and the regulations thereunder and all applicable Laws.
Within thirty (30) calendar days after the Closing Date, Buyer will provide EWI with the proposed Tax Allocation Statements allocating all such amounts as provided herein. The Tax Allocation Statements will become final and binding on the
Parties thirty (30) calendar days after Buyer provides such statements to EWI, unless EWI objects in writing to Buyer, specifying the basis for its objection and preparing an alternative allocation. If EWI does object, the Parties will in good
faith attempt to resolve the dispute within fifteen (15) calendar days of written notice to Buyer of EWI’s objection. Any such resolution will be final and binding on the Parties. Each of the Parties agrees to (a) prepare and timely
file all Tax Returns, including, without limitation, IRS Forms 8023, 8883 and 8594 (and all supplements thereto) in a manner consistent with the Tax Allocation Statements as finalized and (b) act in accordance with the Tax Allocation Statements
for all tax purposes, in each case, to the extent the Parties have agreed to such Tax Allocation Statements. The Parties will revise the Tax Allocation Statements to the extent necessary to reflect any post-Closing payment made pursuant to or in
connection with this Agreement. In the case of any such payment, Buyer will propose revised Tax Allocation Statement(s), and the Parties will follow the procedures outlined above with respect to review, dispute and resolution in respect of such
revision. 
 Section 6.06 Contests. Buyer agrees to give written notice to EWI of the receipt of any written notice by the
Company, Buyer or any of Buyer’s Affiliates which involves the assertion of any claim, or the commencement of any Action, in respect of which an indemnity may be 

  
 43 

 
sought by Buyer pursuant to this Article VI (a “Tax Claim”); provided that the failure to comply with this provision will not affect
Buyer’s right to indemnification hereunder. Buyer will control the contest or resolution of any Tax Claim; provided, however, that Buyer will obtain the prior written consent of EWI (which consent will not be unreasonably withheld or
delayed) before entering into any settlement of a claim or ceasing to defend such claim; and, provided further, that EWI will be entitled to participate in the defense of such claim and to employ counsel of their choice for such purpose, the
fees and expenses of which separate counsel will be borne solely by EWI. 
 Section 6.07 Cooperation and Exchange of
Information. EWI and Buyer will provide each other with such cooperation and information as either of them reasonably may request of the other in filing any Tax Return pursuant to this Article VI or in connection with any audit or other
proceeding in respect of Taxes of the Company. Such cooperation and information will include providing copies of relevant Tax Returns or portions thereof, together with accompanying schedules, related work papers and documents relating to rulings or
other determinations by tax authorities; provided that EWI shall have no obligation to provide any Tax Returns or portions of Tax Returns that do not relate to the Company. Each of EWI and Buyer will retain all Tax Returns, schedules and work
papers, records and other documents in its possession relating to Tax matters of the Company for any taxable period beginning before the Closing Date until the expiration of the statute of limitations of the taxable periods to which such Tax Returns
and other documents relate, without regard to extensions except to the extent notified by the other Party in writing of such extensions for the respective Tax periods. Prior to transferring, destroying or discarding any Tax Returns, schedules and
work papers, records and other documents in its possession relating to Tax matters of the Company for any taxable period beginning before the Closing Date, EWI or Buyer (as the case may be) will provide the other Party with reasonable written notice
and offer the other Party the opportunity to take custody of such materials. 
 Section 6.08 Tax Treatment of Indemnification
Payments. Any indemnification payments pursuant to this Article VI will be treated as an adjustment to the Purchase Price by the Parties for Tax purposes, unless otherwise required by Law. 

Section 6.09 Like-Kind Exchange. EWI and Buyer hereby agree that Buyer and EWI will each have the right at any time prior to the
completion of all the transactions that are to occur at Closing to assign all or a portion of its rights under this Agreement to a Qualified Intermediary (as that term is defined in Section 1.1031(k)-1(g)(4)(v) of the Treasury Regulations) or
an Exchange Accommodation Title Holder (as that term is defined in Revenue Procedure 2000-37, 2000-2 CB 308) in order to accomplish the transaction in a manner that will comply with the requirements of a like-kind exchange pursuant to
Section 1031 of the Code. If either Party assigns all or any of its rights under this Agreement for this purpose, the other Party agrees to (i) consent to such Party’s assignment of its rights in this Agreement, which assignment will
be in a form reasonably acceptable to the other Party, provided that any such assignment will not relieve Buyer from its obligations and liabilities under this Agreement, (ii) accept the Purchase Price, as adjusted, or the assignment, as
applicable, from the Qualified Intermediary at Closing and (iii) at Closing convey and assign as directed by Buyer or pay the Adjusted Purchase Price (or any portion thereof) as directed by the EWI, as applicable. If either Party elects to
assign all or any of its rights under this Agreement pursuant to this Section 6.09, such Party will defend, indemnify, and hold harmless the other Party from all claims relating to such election. 

  
 44 

 Section 6.10 Survival. Notwithstanding anything in this Agreement to the contrary,
the provisions of Section 3.20 and this Article VI will survive for the full period of all applicable statutes of limitations (giving effect to any waiver, mitigation or extension thereof) plus sixty (60) days. 

Section 6.11 Overlap. To the extent that any obligation or responsibility pursuant to Article VIII may overlap with an
obligation or responsibility pursuant to this Article VI, the provisions of this Article VI will govern.

 Section 8.05 Indemnification Procedures. The Person making a
claim under this Article VIII is referred to as the “Indemnified Party”, and the Person against whom such claims are asserted under this Article VIII is referred to as the “Indemnifying Party”. 

(a) Third Party Claims. If any Indemnified Party receives notice of the assertion or commencement of any Action made or brought
by any Person who is not a Party or an Affiliate of a Party or a Representative of the foregoing (a “Third Party Claim”) against such Indemnified Party with respect to which the Indemnifying Party is obligated to provide
indemnification under this Agreement, the Indemnified Party will give the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) calendar days after receipt of such notice of such Third Party
Claim. The failure to give such prompt written notice will not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such
failure. Such notice by the Indemnified Party will describe the Third Party Claim in reasonable detail, will include copies of all material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of the Loss that
has been or may be sustained by the Indemnified Party. The Indemnifying Party will have the right to participate in, or by giving written notice to the Indemnified Party, to assume the defense of any Third Party Claim at the Indemnifying
Party’s expense and by the Indemnifying Party’s own counsel, and the Indemnified Party will cooperate in good faith in such defense; provided that if the Indemnifying Party is EWI, such Indemnifying Party will not have
the right to defend or direct the defense of any such Third Party Claim that (x) is asserted directly by or on behalf of a Person that is a material supplier or material customer of the Company or (y) seeks an injunction or other equitable
relief against the Indemnified Party. In the event that the Indemnifying Party assumes the defense of any Third Party Claim, subject to Section 8.05(b), it will have the right to take such action as it deems necessary to avoid, dispute,
defend, appeal or make counterclaims pertaining to any such Third Party Claim in the name and on behalf of the Indemnified Party. The Indemnified Party will have the right to participate in the defense of any Third Party Claim with counsel selected
by it subject to the Indemnifying Party’s right to control the defense thereof. The fees and disbursements of such counsel will be at the expense of the Indemnified Party, provided that if in the reasonable opinion of
counsel to the Indemnified Party, (A) there are legal defenses available to an Indemnified Party that are different from or additional to those available to the Indemnifying Party or (B) there exists a conflict of interest between the
Indemnifying Party and the Indemnified Party that cannot be waived, the Indemnifying Party will be liable for the reasonable fees and expenses of counsel to the Indemnified Party in each jurisdiction for which the Indemnified Party determines
counsel is required, provided, however, that in such cases the Indemnifying Party may, by written notice to the Indemnified Party, elect to allow the Indemnified Party to assume control and the defense of any such action at 

  
 51 

 
Indemnifying Party’s reasonable costs and expenses . If the Indemnifying Party elects not to compromise or defend such Third Party Claim, fails to promptly notify the Indemnified Party
in writing of its election to defend as provided in this Agreement, or fails to diligently prosecute the defense of such Third Party Claim, or notifies the Indemnified Party in writing that it has elected to allow Indemnified Party to assume the
defense and control of any such Third Party Claims, then (i) the Indemnified Party will assume the defense and control of such Third Party Claim at the Indemnifying Party’s reasonable costs and expenses, and (ii) the Indemnifying
Party will have the right to participate in the defense at its sole cost and expense, subject to Indemnified Party’s right to control the defense. In such instances, the Indemnified Party may, subject to Section 8.05(b), pay,
compromise, defend such Third Party Claim and seek indemnification for any and all Losses based upon, arising from or relating to such Third Party Claim. EWI and Buyer will cooperate with each other in all reasonable respects in connection with the
defense of any Third Party Claim, including making available (subject to the provisions of Section 5.07) records relating to such Third Party Claim and furnishing, without expense (other than reimbursement of actual out-of-pocket
expenses) to the defending party, management employees of the non-defending party as may be reasonably necessary for the preparation of the defense of such Third Party Claim. 

(b) Settlement of Third Party Claims. Notwithstanding any other provision of this Agreement, neither the Indemnifying Party nor
the Indemnified Party will enter into settlement of any Third Party Claim without the prior written consent of the other Party, except as provided in this Section 8.05(b). If a firm offer is made to settle a Third Party Claim without
leading to liability or the creation of a financial or other obligation on the part of the Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection
with such Third Party Claim and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party will give written notice to that effect to the Indemnified Party. If the Indemnified Party fails to consent to such firm offer
within ten days after its receipt of such notice, the Indemnified Party may continue to contest or defend such Third Party Claim and in such event, the maximum liability of the Indemnifying Party as to such Third Party Claim will not exceed the
amount of such settlement offer. If the Indemnified Party fails to consent to such firm offer and also fails to assume defense of such Third Party Claim, the Indemnifying Party may settle the Third Party Claim upon the terms set forth in such firm
offer to settle such Third Party Claim. If the Indemnified Party has assumed the defense pursuant to Section 8.05(a), it will not agree to any settlement without the written consent of the Indemnifying Party (which consent will not be
unreasonably withheld or delayed). 
 (c) Direct Claims. Any Action by an Indemnified Party on account of a Loss which
does not result from a Third Party Claim (a “Direct Claim”) will be asserted by the Indemnified Party giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) days
after the Indemnified Party becomes aware of such Direct Claim. The failure to give such prompt written notice will not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying
Party forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party will describe the Direct Claim in reasonable detail, will include copies of all material written evidence thereof and will indicate the estimated
amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party will have thirty (30) days after its receipt of such notice to respond in writing to such Direct Claim. The 

  
 52 

 
Indemnified Party will allow the Indemnifying Party and its professional advisors to investigate the matter or circumstance alleged to give rise to the Direct Claim, and whether and to what
extent any amount is payable in respect of the Direct Claim and the Indemnified Party will assist the Indemnifying Party’s investigation by giving such information and assistance (including access to the Company’s premises and personnel
and the right to examine and copy any accounts, documents or records) as the Indemnifying Party or any of its professional advisors may reasonably request. If the Indemnifying Party does not so respond within such thirty (30) day period, the
Indemnifying Party will be deemed to have rejected such claim, in which case the Indemnified Party will be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement.

 (d) Tax Claims. Notwithstanding any other provision of this Agreement, the control of any claim, assertion, event or
proceeding in respect of Taxes of the Company (including, but not limited to, any such claim in respect of a breach of the representations and warranties in Section 3.20 hereof or any breach or violation of or failure to fully perform
any covenant, agreement, undertaking or obligation in Article VI) will be governed exclusively by Article VI hereof. 

Section 8.06 Payments. Once a Loss is agreed to by the Indemnifying Party or finally adjudicated to be payable pursuant to this
Article VIII, the Indemnifying Party will satisfy its obligations within fifteen (15) Business Days of such final, non-appealable adjudication by wire transfer of immediately available funds. 

Section 8.07 Tax Treatment of Indemnification Payments. All indemnification payments made under this Agreement will be treated by
the Parties as an adjustment to the Purchase Price for Tax purposes, unless otherwise required by Law. 
 Section 8.08 Exclusive
Remedies. Subject to Section 5.04(d), the Parties acknowledge and agree that their sole and exclusive remedy with respect to any and all claims (other than claims arising from fraud or criminal activity on the part of a Party in
connection with the transactions contemplated herein) for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement, will be pursuant to the
indemnification provisions set forth in Article VI and this Article VIII. In furtherance of the foregoing, each Party hereby waives, to the fullest extent permitted under Law, any and all rights, claims and causes of action for any
breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement it may have against the other Parties and their Affiliates and each of their respective
Representatives arising under or based upon any Law, except pursuant to the indemnification provisions set forth in Article VI and this Article VIII. Nothing in this Section 8.09 will limit any Person’s right to seek
and obtain any equitable relief to which any Person will be entitled or to seek any remedy on account of fraud or criminal activity on the part of a Party in connection with the transactions contemplated herein.

hereof to be performed or complied with by it prior to the Closing; or 
 (v) any Action has been commenced against EWI, the Company or any
of their respective Affiliates that is reasonably likely to prevent the Closing and such Action has not been finally resolved within one hundred twenty (120) days of commencement thereof;

 54 

 (ii) any of the conditions set forth in Section 7.01 or
Section 7.03 will not have been, or if it becomes apparent that any of such conditions will not be, fulfilled by the first anniversary of the date hereof, unless such failure will be due to the failure of EWI to perform or comply with
any of the covenants, agreements or conditions hereof to be performed or complied with by it prior to the Closing;  
 (iii) any
Action has been commenced against Buyers or any of its respective Affiliates that is reasonably likely to prevent the Closing and such Action has not been finally resolved within one hundred twenty (120) days of commencement thereof; or

Representations”) will survive the Closing and will remain in full force and effect until the date that is three (3) years from the Closing Date. 

(b) All covenants and agreements of the Parties contained herein will survive the Closing indefinitely or for the period explicitly
specified therein; provided that the covenants and agreements contained in Article VI will survive the Closing as provided in Article VI. 

(c) Notwithstanding the foregoing, any claims asserted in good faith with reasonable specificity (to the extent known at such time) and in
writing by notice from the non-breaching Party to the breaching Party prior to the expiration date of the applicable survival period will not thereafter be barred by the expiration of the relevant representation or warranty and such claims will
survive until finally resolved. 
 Section 8.02 Indemnification By EWD and EWI. Subject to the other terms, conditions and
limitations of this Article VIII, EWD and EWI, jointly and severally, will indemnify and defend Buyer and each of its Affiliates and their respective Representatives (collectively, the “Buyer Indemnitees”) against, and will
hold each of them harmless from and against, and will pay and reimburse each of them for, any and all Losses incurred or sustained by, or imposed upon, the Buyer Indemnitees based upon, arising out of, with respect to or by reason of: 

  
 35 

 (a) any inaccuracy in or breach of any of the representations or warranties of EWD
contained in this Agreement or in any certificate or instrument delivered by or on behalf of EWD pursuant to this Agreement (other than in respect of Section 3.20 (Taxes), it being understood that the sole remedy for any such inaccuracy
in or breach thereof will be pursuant to Article VI), as of the date such representation or warranty was made or as if such representation or warranty was made on and as of the Closing Date (except for representations and warranties that
expressly relate to a specified date, the inaccuracy in or breach of which will be determined with reference to such specified date); and 

(b) any breach or non-fulfillment of any covenant, agreement or obligation to be performed by EWD pursuant to this Agreement (other than
any breach or violation of, or failure to fully perform, any covenant, agreement, undertaking or obligation in Article VI, it being understood that the sole remedy for any such breach, violation or failure will be pursuant to Article
VI). 
 Section 8.03 Indemnification By Buyer. Subject to the other terms and conditions of this Article VIII,
Buyer will indemnify and defend EWD and its Affiliates and their respective Representatives (collectively, the “EWD Indemnitees”) against, and will hold each of them harmless from and against, and will pay and reimburse each of them
for, any and all Losses incurred or sustained by, or imposed upon, EWD Indemnitees based upon, arising out of, with respect to or by reason of: 

(a) any inaccuracy in or breach of any of the representations or warranties of Buyer contained in this Agreement or in any certificate or
instrument delivered by or on behalf of Buyer pursuant to this Agreement, as of the date such representation or warranty was made or as if such representation or warranty was made on and as of the Closing Date (except for representations and
warranties that expressly relate to a specified date, the inaccuracy in or breach of which will be determined with reference to such specified date); and 

(b) any breach or non-fulfillment of any covenant, agreement or obligation to be performed by Buyer pursuant to this Agreement (other
than Article VI, it being understood that the sole remedy for any such breach thereof will be pursuant to Article VI). 

Section 8.04 Certain Limitations. The indemnification provided for in Section 8.02 and Section 8.03 will
be subject to the following limitations: 
 (a) EWD and EWI will not be liable to the Buyer Indemnitees for indemnification
under Section 8.02(a) or under Section 8.02(a) of the Stock Purchase Agreement with respect to any representations or warranties of EWD hereunder or of EWI and the Company under the Stock Purchase Agreement, other than the Special
Representations (as defined herein and in the Stock Purchase Agreement, and excluding Section 3.15(c) and (d) which, for the avoidance of doubt, will be subject to the Basket), until the aggregate amount of such Losses exceeds
$75,000 (the “Basket”), in which event EWD and EWI will only be required to pay or be liable for all such Losses in excess of the Basket.  

  
 36 

 (b) The aggregate amount of all Losses for which EWD and EWI will be liable pursuant to
Section 8.02(a) and Section 8.02(a) of the Stock Purchase Agreement will not exceed the following: (i) with respect to any representations or warranties of EWD hereunder or of EWI and the Company under the Stock Purchase
Agreement other than the Special Representations (as defined herein and in the Stock Purchase Agreement), $2,500,000 (the “Cap”), (ii) with respect to the Special Representations (as defined herein and in the Stock Purchase
Agreement), $17,000,000 and (iii) with respect to Post-Closing Events hereunder and all “Post-Closing Events” pursuant to the Stock Purchase Agreement, $750,000. In no event shall EWD and EWI be liable to Buyer Indemnitees for any
Losses or other claims relating to or arising out of this Agreement or the other Transaction Documents in excess of $17,000,000. 

(c) Buyer will not be liable to EWD Indemnitees for indemnification under Section 8.03(a) and CLF&P will not be liable

Basket. 
 (d) The aggregate amount of all Losses for which Buyer will be liable pursuant to Section 8.03(a) and
for which CLF&P will be liable pursuant to Section 8.03(a) of the Stock Purchase Agreement (i) other than the Special Representations (as defined herein and in the Stock Purchase Agreement) will not exceed the Cap and (ii) with
respect to the Special Representations (as defined herein and in the Stock Purchase Agreement), will not exceed $17,000,000. 

(e) The determination of the amount of any Losses for purposes of this Article VIII will take into account the amount of
insurance proceeds payable with respect thereto pursuant to any insurance policy. 
 Section 8.05 Indemnification
Procedures. The Person making a claim under this Article VIII is referred to as the “Indemnified Party”, and the Person against whom such claims are asserted under this Article VIII is referred to as the
“Indemnifying Party”. 
 (a) Third Party Claims. If any Indemnified Party receives notice of the assertion or
commencement of any Action made or brought by any Person who is not a Party or an Affiliate of a Party or a Representative of the foregoing (a “Third Party Claim”) against such Indemnified Party with respect to which the
Indemnifying Party is obligated to provide indemnification under this Agreement, the Indemnified Party will give the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) calendar days after
receipt of such notice of such Third Party Claim. The failure to give such prompt written notice will not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits
rights or defenses by reason of such failure. Such notice by the Indemnified Party will describe the Third Party Claim in reasonable detail, will include copies of all material written evidence thereof and will indicate the estimated amount, if
reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party will have the right to participate in, or by giving written notice to the Indemnified Party, to assume the defense of any Third
Party Claim at the Indemnifying Party’s expense and by the Indemnifying Party’s own counsel, and the 

  
 37 

 
Indemnified Party will cooperate in good faith in such defense; provided that if the Indemnifying Party is EWD, such Indemnifying Party will not have the right to defend or direct the
defense of any such Third Party Claim that seeks an injunction or other equitable relief against the Indemnified Party. In the event that the Indemnifying Party assumes the defense of any Third Party Claim, subject to Section 8.05(b), it
will have the right to take such action as it deems necessary to avoid, dispute, defend, appeal or make counterclaims pertaining to any such Third Party Claim in the name and on behalf of the Indemnified Party. The Indemnified Party will have the
right to participate in the defense of any Third Party Claim with counsel selected by it subject to the Indemnifying Party’s right to control the defense thereof. The fees and disbursements of such counsel will be at the expense of the
Indemnified Party, provided that if in the reasonable opinion of counsel to the Indemnified Party, (A) there are legal defenses available to an Indemnified Party that are different from or additional to those available to the
Indemnifying Party or (B) there exists a conflict of interest between the Indemnifying Party and the Indemnified Party that cannot be waived, the Indemnifying Party will be liable for the reasonable fees and expenses of counsel to the
Indemnified Party in each jurisdiction for which the Indemnified Party determines counsel is required, provided, however, that in such cases the Indemnifying Party may, by written notice to the Indemnified Party, elect to allow the
Indemnified Party to assume control and the defense of any such action at Indemnifying Party’s reasonable costs and expenses . If the Indemnifying Party elects not to compromise or defend such Third Party Claim, fails to promptly notify the
Indemnified Party in writing of its election to defend as provided in this Agreement, or fails to diligently prosecute the defense of such Third Party Claim, or notifies the Indemnified Party in writing that it has elected to allow Indemnified Party
to assume the defense and control of any such Third Party Claims, then (i) the Indemnified Party will assume the defense and control of such Third Party Claim at the Indemnifying Party’s reasonable costs and expenses, and (ii) the
Indemnifying Party will have the right to participate in the defense at its sole cost and expense, subject to Indemnified Party’s right to control the defense. In such instances, the Indemnified Party may, subject to
Section 8.05(b), pay, compromise, defend such Third Party Claim and seek indemnification for any and all Losses based upon, arising from or relating to such Third Party Claim. EWD and Buyer will cooperate with each other in all
reasonable respects in connection with the defense of any Third Party Claim, including making available (subject to the provisions of Section 5.07) records relating to such Third Party Claim and furnishing, without expense (other than
reimbursement of actual out-of-pocket expenses) to the defending party, management employees of the non-defending party as may be reasonably necessary for the preparation of the defense of such Third Party Claim. 

(b) Settlement of Third Party Claims. Notwithstanding any other provision of this Agreement, neither the Indemnifying Party nor
the Indemnified Party will enter into settlement of any Third Party Claim without the prior written consent of the other Party, except as provided in this Section 8.05(b). If a firm offer is made to settle a Third Party Claim without
leading to liability or the creation of a financial or other obligation on the part of the Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection
with such Third Party Claim and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party will give written notice to that effect to the Indemnified Party. If the Indemnified Party fails to consent to such firm offer
within ten days after its receipt of such notice, the Indemnified Party may continue to contest or defend such Third Party Claim and in such event, the maximum liability of the Indemnifying Party as to 

  
 38 

 
such Third Party Claim will not exceed the amount of such settlement offer. If the Indemnified Party fails to consent to such firm offer and also fails to assume defense of such Third Party
Claim, the Indemnifying Party may settle the Third Party Claim upon the terms set forth in such firm offer to settle such Third Party Claim. If the Indemnified Party has assumed the defense pursuant to Section 8.05(a), it will not agree
to any settlement without the written consent of the Indemnifying Party (which consent will not be unreasonably withheld or delayed). 
 (c)
Direct Claims. Any Action by an Indemnified Party on account of a Loss which does not result from a Third Party Claim (a “Direct Claim”) will be asserted by the Indemnified Party giving the Indemnifying Party reasonably
prompt written notice thereof, but in any event not later than thirty (30) days after the Indemnified Party becomes aware of such Direct Claim. The failure to give such prompt written notice will not, however, relieve the Indemnifying Party of
its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party will describe the Direct Claim in reasonable detail, will include
copies of all material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party will have thirty (30) days after
its receipt of such notice to respond in writing to such Direct Claim. The Indemnified Party will allow the Indemnifying Party and its professional advisors to investigate the matter or circumstance alleged to give rise to the Direct Claim, and
whether and to what extent any amount is payable in respect of the Direct Claim and the Indemnified Party will assist the Indemnifying Party’s investigation by giving such information and assistance (including access to EWD’s premises and
personnel and the right to examine and copy any accounts, documents or records) as the Indemnifying Party or any of its professional advisors may reasonably request. If the Indemnifying Party does not so respond within such thirty (30) day
period, the Indemnifying Party will be deemed to have rejected such claim, in which case the Indemnified Party will be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this
Agreement. 
 (d) Tax Claims. Notwithstanding any other provision of this Agreement, the control of any claim, assertion, event or
proceeding in respect of Taxes with respect to the Pipeline Assets (including, but not limited to, any such claim in respect of a breach of the representations and warranties in Section 3.20 hereof or any breach or violation of or
failure to fully perform any covenant, agreement, undertaking or obligation in Article VI) will be governed exclusively by Article VI hereof. 

Section 8.06 Payments. Once a Loss is agreed to by the Indemnifying Party or finally adjudicated to be payable pursuant to this
Article VIII, the Indemnifying Party will satisfy its obligations within fifteen (15) Business Days of such final, non-appealable adjudication by wire transfer of immediately available funds. 

Section 8.07 Tax Treatment of Indemnification Payments. All indemnification payments made under this Agreement will be
treated by the Parties as an adjustment to the Purchase Price for Tax purposes, unless otherwise required by Law. 

  
 39 

 Section 8.08 Exclusive Remedies. Subject to Section 5.04(d), the Parties
acknowledge and agree that their sole and exclusive remedy with respect to any and all claims (other than claims arising from fraud or criminal activity on the part of a Party in connection with the transactions contemplated herein) for any breach
of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement, will be pursuant to the indemnification provisions set forth in Article VI and this
Article VIII. In furtherance of the foregoing, each Party hereby waives, to the fullest extent permitted under Law, any and all rights, claims and causes of action for any breach of any representation, warranty, covenant, agreement or
obligation set forth herein or otherwise relating to the subject matter of this Agreement it may have against the other Parties and their Affiliates and each of their respective Representatives arising under or based upon any Law, except pursuant to
the indemnification provisions set forth in Article VI and this Article VIII. Nothing in this Section 8.09 will limit any Person’s right to seek and obtain any equitable relief to which any Person will be entitled or
to seek any remedy on account of fraud or criminal activity on the part of a Party in connection with the transactions contemplated herein. 

ARTICLE IX 

TERMINATION 

Section 9.01 Termination. This Agreement may be terminated at any time prior to the Closing: 

(a) by the mutual written consent of EWD and Buyer;

made by EWD pursuant to this Agreement, that in either case would give rise to the failure of any of the conditions specified in Article VII and such breach, inaccuracy or failure has not been cured within thirty (30) days of EWD’s
receipt of written notice of such breach from Buyer, provided that if such breach, inaccuracy or failure cannot reasonably be cured within thirty (30) days, then the cure period shall be extended for one additional thirty (30) day
period so long as EWD diligently and in good faith commence to cure the breach, inaccuracy or failure within the initial thirty (30) day cure period and continue to diligently and in good faith attempt to cure the breach during the second

any of such conditions will not be, fulfilled by the date that is eighteen (18) months after the date hereof, unless such failure will be due to the failure of Buyer to perform or comply with any of the covenants, agreements or conditions
hereof to be performed or complied with by it prior to the Closing; or 

  
 40 

 (v) any Action has been commenced against EWD or any of its Affiliates that is reasonably likely

provision of the Stock Purchase Agreement and there has been a breach, inaccuracy in or failure to perform any representation, warranty, covenant or agreement made by Buyer pursuant to this Agreement that would give rise to the failure of any of the
conditions specified in Article VII and such breach, inaccuracy or failure has not been cured within thirty (30) days of Buyer’s receipt of written notice of such breach from EWD; or 

(ii) any of the conditions set forth in Section 7.01 or Section 7.03 will not have been, or if it becomes
apparent that any of such conditions will not be, fulfilled by the first anniversary of the date hereof, unless such failure will be due to the failure of EWD to perform or comply with any of the covenants, agreements or conditions hereof to be
performed or complied with by it prior to the Closing; 
 (iii) any Action has been commenced against Buyer or any of its respective
Affiliates that is reasonably likely to prevent the Closing and such Action has not been finally resolved within one hundred twenty (120) days of commencement thereof; or

the same extent as if they were set forth verbatim herein. 
 Section 10.04 Headings. The headings in this Agreement are for
reference only and will not affect the interpretation of this Agreement. 
 Section 10.05 Severability. If any term or provision
of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in

respective successors and permitted assigns. No Party may assign its rights or obligations hereunder without the prior written consent of the other Parties, which consent will not be unreasonably withheld or delayed; provided, however, prior
