AGREEMENT 
 NOW THEREFORE, in consideration of the premises and mutual promises herein made, and in consideration of the representations, warranties, covenants and agreements herein contained, Parent, Merger
Subsidiary, Sister Subsidiary, ECS, and the Members hereby agree as follows: 
 1. THE MERGER 

1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, at Closing the parties hereto shall cause
the Merger to be consummated by ECS and Merger Subsidiary executing and delivering Articles of Merger (the “Articles of Merger”), substantially in the form attached hereto as Exhibit A, which, together with this Agreement or
an appropriate Plan of Merger, shall be filed at Closing with the Secretary of State of the State of Florida in accordance with the FBCA, and the Secretary of State of the State of Nevada, along with all other required documents, in accordance with
the NRS. Subject to the terms and conditions of this Agreement, at the Effective Time, Merger Subsidiary shall be merged with and into ECS in accordance with, and with the effects provided in, the applicable provisions of the FBCA and the NRS. ECS
shall be the Surviving Entity (sometimes hereinafter referred to as the “Surviving Entity”) resulting from the Merger and, as a result, shall become a wholly owned subsidiary of Parent, shall continue to be governed by the laws of
the State of Nevada and shall succeed to and assume all of the rights and obligations of Merger Subsidiary, and the separate corporate existence of Merger Subsidiary shall cease. 

1.2 Effective Time. The Merger shall become effective upon (i) the Articles of Merger having been accepted for filing by the
Secretary of State of the State of Nevada or (ii) at such later time as is set forth in the Articles of Merger (the “Effective Time”). The Merger shall have the effects set forth in Section 92A.250 of the NRS and
Section 607.1106 of the FBCA. 
 1.3 Closing. 

1.3.1 Time and Place of Closing. The Closing of the Contemplated Transactions (the “Closing”) shall take place at

Traurig, P.A, located at 333 Avenue of the Americas, Miami, Florida 33131, unless another time, date or place is agreed to in writing by the parties hereto. Subject to the provisions of Section 8, failure to consummate the Merger on the
date and time and at the place determined pursuant to this Section 1.3.1 shall not result in the termination of this Agreement or relieve any party of any obligation under this Agreement. Notwithstanding the time and date upon which the
Closing actually occurs, for purposes of determining a change in control in accordance with GAAP, if the Closing occurs on any day of a calendar month other than the first, then the Closing shall be deemed to have occurred and become effective as of
12:01 a.m. Coral Gables, FL time on the first day of such calendar month. Notwithstanding anything to the contrary set forth herein and for purposes of clarity, the Closing Balance Sheet shall be prepared and determined as of the date upon which
Closing actually occurs, without regard to the previous sentence. All deliveries, payments and other transactions and documents relating to the Closing shall be interdependent and none shall be effective unless and until all are effective (except

shall continue to hold 100% of the membership interest of Sister Subsidiary. 
 1.4.3 After the Subsequent Merger, references
herein to the Surviving Entity shall refer to Sister Subsidiary. 
 1.4.4 This Agreement is intended to constitute a “plan
of reorganization” with respect to the Merger and Subsequent Merger, taken together, for United States Federal Income Tax purposes pursuant to which, for such purposes, the Merger and the Subsequent Merger, taken together, are to be treated as
a “reorganization” under section 368(a) of the Code (to which each of Parent, Sister Subsidiary and ECS are to be parties under section 368(b) of the Code) in which ECS is to be treated as merging directly with and into Sister Subsidiary
with the Units converted in such Merger as provided for in Section 1.8. 
 1.5 Governing Documents.

 1.5.1 At the Effective Time, the Articles of Organization of ECS, as in effect immediately prior to the Effective Time of the
Merger, shall be the Articles of Organization of the Surviving Entity. At the effective time of the Subsequent Merger, the Articles of Organization of Sister Subsidiary, as in effect immediately prior to such effective time, shall be the Articles of
Organization of Sister Subsidiary until thereafter changed or amended as provided therein or by applicable Law (the “Articles of Organization”), except that Article I thereof shall be amended, by the filing of Articles of Merger or
other appropriate documents, to read in its entirety as follows: “the name of the Limited Liability Company is EC Source Services, LLC.”

1.7 Management. The officers of Merger Subsidiary immediately prior to the Effective Time shall be the officers of the Surviving
Entity at the Effective Time. The officers of the Surviving Entity immediately prior to the effective time of the Subsequent Merger shall be the officers of Sister Subsidiary at such effective time, to serve until the earlier of their resignation or

become 100% of the membership interest of the Surviving Entity. 
 1.8.2 Each Common Unit issued and outstanding immediately
prior to the Effective Time shall be converted into the right to receive, upon surrender of the certificates formally representing all such membership interest units (the “Certificates”), the Per Unit Merger Consideration. As of the

“Per Unit Closing Date Merger Consideration” shall be equal to that number of Parent Shares equal to the quotient of: 
 (i) Subject to adjustment as set forth in Sections 1.10.3 and 1.11.4, the sum of (such sum, the “Total Parent Shares”) (A) 5,153,846 (such number being subject to adjustment
as appropriate for any stock splits, stock dividends, share combinations or the like) plus (B) the quotient of (1) the aggregate exercise price of the ECS Options outstanding immediately prior to the Effective Time of the Merger,
divided by (2) $13; divided by 

 (ii) the number of Unit Equivalents outstanding immediately prior to the
Effective Time of the Merger. 
 (b) No later than the second Business Day prior to the Closing Date, ECS shall
deliver to Parent Schedule 1.9.1(b) setting forth the name of each ECS Member, the name of each holder of ECS Options (each, an “Option Holder” and collectively, the “Option Holders”), the number of Common
Units and/or ECS Options held by each and (i) the Per Unit Closing Date Merger Consideration to be paid by Parent to such ECS Member at the Closing in accordance with Section 1.8.2 and this Section 1.9.1 or (ii) the
consideration to be paid by Parent to such Option Holder at the Closing in accordance with Section 1.15 (the “Option Consideration”). Schedule 1.9.1(b) shall also include wire instructions or other payment
instructions for each ECS Member for any Earn-Out Payment to be paid in cash, in Parent’s sole discretion, as set forth in Section 1.9.2. 
 (c) The Per Unit Closing Date Merger Consideration shall be issued in accordance with Section 1.12. 
 1.9.2 Earn-Out Payments. 
 (a) In addition to the Per Unit Closing
Date Merger Consideration, Parent shall pay to each ECS Member such ECS Member’s Common Unit Percentage of each Earn-Out Payment (the “Per Unit Earn-Out Merger Consideration”) as determined pursuant to this
Section 1.9.2 at the times, in the manner and to the extent an Earn-Out Payment is earned. An “Earn-Out Payment” shall be earned for an Earn-Out Period if the Net EBITDA of the Companies on a consolidated basis for such
Earn-Out Period is greater than the EBITDA Threshold for such Earn-Out Period and the amount of such Earn-Out Payment shall be equal to (i) 20% multiplied by (ii) the excess of (x) the Net EBITDA of the Companies on a consolidated
basis for such Earn-Out Period minus (y) the EBITDA Threshold for such Earn-Out Period. 
 (b) For purposes
of this Section 1.9.2, the following terms are defined as follows: 
 (i) “First Earn-Out
Period” shall mean the period commencing with the first day of the first calendar month immediately after the Closing Date and ending on the last day of such fiscal year. 

(ii) “Second Earn-Out Period” shall mean the period commencing with the first day of the first full
fiscal year commencing immediately after the Closing Date and ending on the last day of such fiscal year. 

(iii) “Third Earn-Out Period” shall mean the period commencing with the first day of the second full
fiscal year commencing immediately after the Closing Date and ending on the last day of such fiscal year. 

(iv) “Fourth Earn-Out Period” shall mean the period commencing with the first day of the third full
fiscal year commencing immediately after the Closing Date and ending on the last day of such fiscal year. 
 (v)
“Fifth Earn-Out Period” shall mean the period commencing with the first day of the fourth full fiscal year commencing immediately after the Closing Date and ending on the last day of such fiscal year. 

(vi) “Sixth Earn-Out Period” shall mean the period commencing with the first day of the fifth full
fiscal year commencing immediately after the Closing Date and ending on the day immediately preceding the fifth anniversary of the first day of the First Earn-Out Period. 

(vii) Each of the “First Earn-Out Period,” “Second Earn-Out Period,” “Third Earn-Out
Period,” “Fourth Earn-Out Period,” “Fifth Earn-Out Period” and “Sixth Earn-Out Period” is an “Earn-Out Period.” 

 (viii) “EBITDA Threshold” means (a) $15,000,000 for
each of the Second Earn-Out Period, Third Earn-Out Period, Fourth Earn-Out Period and Fifth Earn-Out Period and, (b) for each of the First Earn-Out Period and the Sixth Earn-Out Period, an amount equal to the product of $1,250,000 multiplied by
the number of calendar months included in the First Earn-Out Period and Sixth Earn-Out Period, respectively. 

(ix) “Net EBITDA” for any Earn-Out Period means EBITDA of the Companies on a consolidated basis for such
Earn-Out Period, minus the amount by which Net EBITDA of the Companies on a consolidated basis was negative for the prior Earn-Out Period, if applicable. For example, if the Companies on a consolidated basis have Net EBITDA in the First Earn-Out
Period of negative $1,000,000 and EBITDA in the Second Earn-Out Period of $15,500,000, then Net EBITDA for the Second Earn-Out Period would be $14,500,000. 
 (x) “EBITDA” means for any Earn-Out Period the sum of (a) the net income or loss generated by the Companies’ operations, on a consolidated basis, as they exist at the Effective
Time and as they may grow or contract after the Closing Date in the normal course of business through internal growth and not through acquisitions or other extraordinary or non-recurring transactions (the “Existing Operations”),
after deduction of all costs, expenses, interest, taxes, depreciation, amortization, and other proper charges from the Existing Operations (to include costs and expenses for services or benefits provided to the Companies by Parent and its Affiliates
but subject to the limitations set forth in this paragraph) (including (i) the cost of any bonuses or incentive payments earned with respect to the applicable period (excluding any Earn-Out Payment), (ii) the cost of any equity granted to
employees, or other derivative securities granted during the applicable period, valued in accordance with the Black-Scholes model and amortized over the vesting period of any equity granted, (iii) the cost of capitalized leases, amortized over
the lease term and (iv) all interest and amortization expense (but excluding principal repayments) with respect to the Companies’ Debt, including all Debt reflected on the Closing Balance Sheet), in each case of (i) through
(iv) as attributable to the Existing Operations (to include costs and expenses for services or benefits provided to the Companies by Parent and its Affiliates but subject to the limitations set forth in this paragraph) plus (b) all
(i) interest expense (ii) federal, state, or local taxes to the extent based upon net income and not revenue, (iii) depreciation expense, and (iv) amortization expense, in each case of (i) through (iv) as attributable
to the Existing Operations, but only to the extent deducted in determining the amount in clause (a). In determining the costs to be deducted in calculating net income or loss under clause (a), any costs for services or benefits provided to the
Companies by Parent or any Affiliate of Parent shall not exceed Parent’s or such Affiliate’s actual cost of furnishing such services or benefits. 
 (c) Unless there is a disagreement as described in subsection (e) of this Section 1.9.2, Parent will pay to the ECS Members the Earn-Out Payment with respect to a specific Earn-Out
Period, if any Earn-Out Payment is owed, no later than the 121st day after the end of such Earn-Out Period, at Parent’s option (i) in cash in immediately available funds or (ii) in Parent Shares, valued at the average daily closing
price for Parent Shares as reported by the New York Stock Exchange (or as quoted on such other principal U.S. exchange or over-the-counter market on which Parent Shares are then traded) for those trading days occurring during the 60 calendar days
immediately preceding the date such Parent Shares are issued (such aggregate price for any Earn-Out Period, the “Earn-Out Period Share Value”) or (iii) in any combination of cash in immediately available funds or Parent Shares.
If Parent issues Parent Shares for all, or any portion, of any Earn-Out Payment, such shares, at the time of their issuance, will be validly issued, fully paid and nonassessable. 

(d) Except as set forth in Section 1.9.2(h), the continued employment of the ECS Members by the Companies,
Parent or their Affiliates is not a condition to Parent’s obligation to pay any Earn-Out Payment, if earned; provided that nothing in this Agreement constitutes an agreement or understanding to employ for a term of years or otherwise guarantee
any ECS Member’s employment with the Companies, Parent or their Affiliates following the Closing. 
 (e) On
or prior to the 90th day after the end of the applicable Earn-Out Period, Parent will calculate the Earn-Out Payment, if any, for such period and provide to the Members’ Representative Parent’s calculation of the Earn-Out Payment. For
thirty (30) days following Parent’s delivery of the Earn-Out Payment calculation to the Members’ Representative (the “Earn-Out Review Period”), the Members’ Representative may review the Earn-Out Payment
calculation and other documentation. During the Earn-Out Review Period, Parent shall provide the Members’ Representative with access to all books and records reasonably requested to review Parent’s calculation of the Earn-Out Payment. If
the Members’ Representative objects to the amount of the Earn-Out Payment for any reason, the Members’ Representative shall, on or before the last day of the Earn-Out Review Period, so inform Parent, in writing (an “Earn-Out
Objection”), setting forth a specific description of the basis of the Members’ Representative’s determination and the adjustments to the Earn-Out Payment that the Members’ Representative believes should be

 
made. To the extent any disagreement therewith is not described in an Earn-Out Objection received by Parent on or before the last day of the Earn-Out Review Period, then the Earn-Out Payment
calculation prepared by Parent and delivered to the Members’ Representative shall be deemed agreed, final and binding on the parties. If the Members’ Representative timely delivers an Earn-Out Objection to Parent, and Parent and the
Members’ Representative are unable to resolve all of their disagreements with respect to the Earn-Out Payment within thirty (30) days after the end of the Earn-Out Review Period, then Parent and the Members’ Representative shall
jointly retain the CPA Firm, which, acting as an expert and not as an arbitrator, shall determine, on the basis set forth in and in accordance with this Section 1.9.2(e), and only with respect to those specific adjustments in the
Earn-Out Objection on which Parent and the Members’ Representative have not agreed, whether and to what extent, if any, the Earn-Out Payment amount requires adjustment. Parent and the Members’ Representative shall instruct the CPA Firm to
deliver its written determination to Parent and the Members’ Representative no later than 30 days after submitting the matter to it for resolution. At the time of retention of the CPA Firm, Parent shall specify in writing to the CPA Firm and
the Members’ Representative the amount of Parent’s computation of the Earn-Out Payment (the “Parent’s Earn-Out Position”), and the Members’ Representative shall specify in writing to the CPA Firm and to Parent
the amount of the Members’ Representative’s computation of the Earn-Out Payment (the “Members’ Representative’s Earn-Out Position”). The CPA Firm’s determination shall be conclusive and binding upon the
parties. In resolving any disputed item, the CPA Firm may not assign a value to any disputed item that is greater than the greatest value claimed by Parent or the Members’ Representative at the time the CPA Firm is retained or less than the
smallest value claimed for the item by Parent or the Members’ Representative at such time. The scope of the disputes to be resolved by the CPA Firm is limited to whether the calculation of the Earn-Out Payment was done in a manner consistent
with GAAP and in accordance with this Agreement, and the CPA Firm is not to make any other determination unless jointly requested in writing by the Members’ Representative and Parent. The fees and disbursements of the CPA Firm and the
reasonable attorneys’ fees and expenses of the parties relating to the disputes submitted to the CPA Firm (collectively, the “Earn-Out Dispute Expenses”) shall be borne (i) jointly and severally by the Members in that
proportion equal to a fraction (expressed as a percentage) the numerator of which is equal to Members’ Representative’s Earn-Out Position minus the Earn-Out Payment determined by the CPA Firm, and the denominator of which is equal to
Members’ Representative’s Earn-Out Position minus Parent’s Earn-Out Position and (ii) by Parent in that proportion equal to a fraction (expressed as a percentage) equal to one (1) minus the fraction described in clause (i).
For example, if the Members’ Representative’s Earn-Out Position is that the Earn-Out Payment should be $5,000,000 and Parent’s Earn-Out Position is that the Earn-Out Payment should be $4,000,000, the CPA Firm determines that the
Earn-Out Payment should be $4,600,000 and the Earn-Out Dispute Expenses are $50,000, then (i) the Members shall jointly and severally pay $20,000 (40%) of the Earn-Out Dispute Expenses and (ii) Parent shall pay $30,000 (60%) of
the Earn-Out Dispute Expenses. Parent and the Members shall cooperate with the CPA Firm during its resolution of the disagreement and make readily available to the CPA Firm all relevant books and records and any work papers (including those of the
parties’ respective accountants, to the extent permitted by such accountants) relating to the determination of the Earn-Out Payment and all other items reasonably requested by the CPA Firm in connection therewith. 

(f) Following the Closing Date, Parent will continue to operate the Companies during the period for which the ECS Members
are entitled to Earn-Out Payments substantially as previously operated, subject to the business requirements of Parent and its Affiliates taken as a whole. Parent will be permitted, following the Closing Date, to make changes in its sole discretion
to the operations, corporate organization, personnel, accounting practices, and other aspects of the Companies and the Businesses so long as such changes are made in good faith, in the best interests of the Companies, Parent, and their respective
Affiliates or to conform to standard practices applicable generally to other Parent Affiliates, and not with the specific intent of reducing amounts that otherwise would be payable to the ECS Members. 

(g) Limited Transferability of Earn-Out. Without Parent’s prior written consent, which may be withheld in
Parent’s sole discretion, each ECS Member’s rights to receive Earn-Out Payments, if any, are personal to such ECS Member and shall not, in whole or in part, be sold, transferred, assigned or otherwise conveyed or pledged or encumbered or
have Encumbrances created with respect to them; provided, however, that subject to Parent’s prior written consent, which consent may not be unreasonably withheld, a Non-Entity Member may transfer such right to a Member of the Immediate Family
of such Non-Entity Member as a result of his death or in connection with bona fide estate planning purposes, in each case subject to the transferee’s agreeing in writing to the terms and conditions of this Section 1.9.2 and with a
copy of such written agreement being promptly provided to Parent. 
 (h) Forfeiture of Earn-Out Payments. If
Parent reasonably believes any ECS Member or Indirect Member (a “Defaulting Member”) is in breach of Section 5.1 or 5.2 (each a “Non-Competition Obligation”) or Section 5.5 (a “Lockup
Obligation”), Parent shall provide such Defaulting Member with written notice of such alleged breach (a “Default Notice”), which Default Notice shall include a description of the acts that Parent has reasonably determined
constitute a breach of the Non-Competition Obligations or a Lockup Obligation. No later than thirty (30) days after the Defaulting Member’s receipt of a Default Notice, such Defaulting Member shall provide Parent with written notice
(“Objection Notice”) if such Defaulting Member objects to Parent’s determination. To the extent a disagreement with a 

 
Default Notice is not described in a timely Objection Notice, no such disagreement may be raised by the Defaulting Member and with respect to any such disagreement, Parent’s determination
shall be conclusive, final and binding on the parties. In addition to any other remedies available to it, if a Defaulting Member admits in writing to a breach of a Non-Competition Obligation or a Lockup Obligation, fails to timely deliver an
Objection Notice as set forth above or is found by a court with jurisdiction to have breached a Non-Competition Obligation or a Lockup Obligation, Parent may terminate all of the Defaulting Member’s rights under this Agreement to any Earn-Out
Payments, or in the case of an Indirect Member who is a Defaulting Member, all of the Entity Members’ rights under this Agreement to any Earn-Out Payments, and which, in any such case, if already paid shall be refunded to Parent by the
Defaulting Member. If the Defaulting Member provides Parent with an Objection Notice, Parent and the Defaulting Member shall negotiate in good faith to resolve such differences. If the parties are unable to resolve their disagreement within 60 days
after Parent’s receipt of the Objection Notice, either party may submit such dispute to a court with jurisdiction as set forth in Section 11.15. Any such termination with respect to the Defaulting Member shall not affect the rights
of any other ECS Member under this Agreement to any Earn-Out Payments, except as set forth above with respect to the Indirect Members and Entity Members. Nothing in this Section 1.9.2(h) shall preclude Parent from seeking immediate
injunctive relief for any breach or threatened breach of a Non-Competition Obligation or Lockup Obligation; nor shall it limit any other remedies available to Parent under this Agreement or applicable Law. 

1.10 Estimate of Net Working Capital, Tangible Net Worth; PP&E. 

1.10.1 At least five (5) Business Days prior to the Closing Date, ECS shall prepare in accordance with GAAP and deliver to Parent
ECS’s good faith reasonable estimate of the Companies’ consolidated balance sheet as of the Closing Date (the “Estimated Closing Balance Sheet”) and a certificate (substantially in the form of Exhibit C) executed by
both the chief executive officer and the chief financial officer of each Company (the “Closing Certificate”) setting forth ECS’s estimate of each of the following as set forth on the Estimated Closing Balance Sheet: 

(a) Net Working Capital (the “Estimated Net Working Capital”); 

(b) Tangible Net Worth (the “Estimated Tangible Net Worth”); and 

(c) the net book value of the PP&E (the “Estimated PP&E”). 

1.10.2 Following receipt of the Closing Certificate, ECS shall permit Parent and its Representatives at all reasonable times and upon
reasonable notice to review ECS’s and its accountants’ working papers relating to the Estimated Closing Balance Sheet and Closing Certificate as well as the Companies’ accounting books and records relating to the determination of the
Estimated Closing Balance Sheet and Closing Certificate, and ECS shall make reasonably available its Representatives responsible for the preparation of the Estimated Closing Balance Sheet and the Closing Certificate in order to respond to the
inquiries of Parent. 
 1.10.3 The Total Parent Shares shall be reduced as follows: 

(a) if the Estimated PP&E is less than eight million dollars ($8,000,000) (the “PP&E Target
Amount”), the Total Parent Shares shall be reduced by the quotient of (1) the difference between the PP&E Target Amount minus the Estimated PP&E divided by (2) $13; 

(b) if the Estimated Net Working Capital is less than one million one hundred thousand dollars ($1,100,000) (the
“Net Working Capital Target Amount”), the Total Parent Shares shall be reduced by the quotient of (1) the difference between the Net Working Capital Target Amount minus the Estimated Net Working Capital, divided by
(2) $13; and 
 (c) if the Estimated Tangible Net Worth is less than eight million dollars ($8,000,000) (the
“Tangible Net Worth Target Amount”), the Total Parent Shares shall be reduced by the quotient of (1) the difference between the Tangible Net Worth Target Amount minus the Estimated Tangible Net Worth, divided by (2) $13;
provided however, that (i) if the Estimated PP&E is less than the PP&E Target Amount, the Tangible Net Worth Target Amount shall be reduced by the amount of such deficit and (ii) if Estimated Net Working Capital is less than the
Net Working Capital Target Amount, the Tangible Net Worth Target Amount shall be reduced by the amount of such deficit. 

1.10.4 In the event that all of (and only if all of): (i) the Estimated PP&E exceeds the PP&E Target Amount (such excess, if
any exists, the “PP&E Excess”), (ii) the Estimated Net Working Capital exceeds the sum of: (x) the Net Working Capital Target Amount plus (y) the Unpaid Preferred Dividend (such excess, if any exists, the
“Net Working Capital Excess”), and (iii) the Estimated Tangible Net Worth exceeds the sum of: (x) Tangible Net Worth Target Amount plus (y) the Unpaid Preferred Dividend (such excess, if any exists, the
“Tangible Net Worth Excess”), Parent shall pay to each ECS Member immediately prior to the Closing an amount of cash in 

 
immediately available funds equal to such ECS Member’s Common Unit Percentage of the Excess Cash. For purposes of this Agreement, “Excess Cash” means the product of:
(i) sixty-seven percent (67%) multiplied by (ii) the lesser of (x) the Net Working Capital Excess and (y) the Tangible Net Worth Excess. 
 1.11 Post-Closing Purchase Price Adjustment. 
 1.11.1 As soon as
practicable but in no event more than one hundred twenty (120) days following the Closing Date, Parent shall prepare, or cause to be prepared, and deliver to the Members’ Representative: (a) a consolidated balance sheet of the
Companies as of the Closing Date prepared in accordance with GAAP (the “Closing Balance Sheet”); and (b) a certificate substantially in the form of Exhibit D executed by the Chief Financial Officer of Parent (the
“Final Closing Statement”) setting forth each of the following as set forth on the Closing Balance Sheet: (i) the actual Net Working Capital (“Actual Net Working Capital”); (ii) the actual Tangible Net
Worth (“Actual Tangible Net Worth”); and (iii) the actual net book value of PP&E (the “Actual PP&E”). 
 1.11.2 Members’ Representative and its accountants shall complete their review of the Closing Balance Sheet and Final Closing Statement within 30 days after delivery thereof by Parent. During such
review period, Parent shall provide Members’ Representative with access to all books and records reasonably requested by Members’ Representative to review the Closing Balance Sheet and the Final Closing Statement. If the Members’
Representative objects to the Closing Balance Sheet or Final Closing Statement for any reason, the Members’ Representative shall, on or before the last day of such 30-day period, so inform Parent in writing (a “ECS Members’
Objection”), setting forth a specific description of the basis of the Members’ Representative’s determination and the adjustments to the Closing Balance Sheet or Final Closing Statement that the Members’ Representative
believes should be made. To the extent any disagreement therewith is not described in a ECS Members’ Objection received by Parent on or before the last day of such 30-day period, then all items described on the Closing Balance Sheet and Final
Closing Statement delivered by Parent to the Members’ Representative shall be deemed agreed, final and binding on the parties. 
 1.11.3 If the Members’ Representative timely delivers a ECS Members’ Objection to Parent and the Members’ Representative and Parent are unable to resolve all of their disagreements with
respect to the proposed adjustments set forth in ECS Members’ Objection within thirty (30) days following Parent’s receipt of the ECS Members’ Objection, then they shall jointly retain the CPA Firm, which, acting as an expert and
not as an arbitrator, shall determine, on the basis set forth in and in accordance with this Section 1.11, and only with respect to those items in ECS Members’ Objection on which the Members’ Representative and Parent have not
agreed, whether and to what extent, if any, the number of Total Parent Shares or Excess Cash, if applicable, requires adjustment. Parent and the Members’ Representative shall instruct the CPA Firm to deliver its written determination to Parent
and the Members’ Representative no later than 30 days after submitting the matter to it for resolution. At the time of retention of the CPA Firm, Parent shall specify in writing to the CPA Firm and the Members’ Representative Parent’s
computation of the Total Parent Shares and Excess Cash, if applicable (the sum of: (i) such Total Parent Shares plus (ii) the quotient of (x) such Excess Cash divided (y) $13, the “Parent’s
Position”), and the Members’ Representative shall specify in writing to the CPA Firm and to Parent the Members’ Representative’s computation of the Total Parent Shares and Excess Cash, if applicable (the sum of: (i) such
Total Parent Shares plus (ii) the quotient of (x) such Excess Cash divided by (y) $13, the “Members’ Representative’s Position”). The CPA Firm’s determination shall be conclusive and binding upon
the Members’ Representative, Parent and the Members. In resolving any disputed item, the CPA Firm may not assign a value to any disputed item that is greater than the greatest value claimed by the Members’ Representative in calculating the
Members’ Representative’s Position or Parent in calculating the Parent’s Position or less than the smallest value claimed for such item by the Members’ Representative in calculating the Members’ Representative’s
Position or Parent in calculating Parent’s Position at such time. The scope of the disputes to be resolved by the CPA Firm is limited to whether the preparation of the Closing Balance Sheet and the calculation of Actual Net Working Capital,
Actual Tangible Net Worth and Actual PP&E, were done in a manner consistent with GAAP and otherwise in accordance with this Agreement, and the CPA Firm is not to make any other determination unless jointly requested in writing by the
Members’ Representative and Parent. The fees and disbursements of the CPA Firm and the reasonable attorneys’ fees and expenses of the parties relating to the disputes submitted to the CPA Firm (collectively, the “Merger
Consideration Dispute Expenses”) shall be borne (i) jointly and severally by the Members in that proportion equal to a fraction (expressed as a percentage rounded to one decimal place) the numerator of which is equal to Members’
Representative’s Position minus the CPA Firm’s Position, and the denominator of which is equal to Members’ Representative’s Position minus Parent’s Position and (ii) by Parent in that proportion equal to a fraction
(expressed as a percentage) equal to one (1) minus the fraction described in clause (i). For the purposes of this Agreement the “CPA Firm’s Position” means the sum of: (i) the Total Parent Shares determined by the CPA
Firm plus (ii) the quotient of (x) the Excess Cash determined by the CPA Firm divided by (y) $13. For example, if Parent’s Position is that Total Shares should be 5,000,000 Parent Shares and Excess Cash $0, the
Members’ Representative’s Position is that Total Shares should be 5,200,000 Parent Shares and Excess Cash $1 million, and the CPA Firm determines that the Total Shares should be 5,100,000 Parent Shares and Excess Cash $0 and the Merger
Consideration Dispute Expenses are $50,000, then: (i) Parent shall pay $18,050 (36.1%)f the Merger Consideration Dispute Expenses and (ii) the Members shall jointly and severally pay $31,950 (63.9%) of the Merger Consideration Dispute
Expenses. The Members’ Representative and Parent shall cooperate with the CPA Firm during its resolution of the disagreement and make readily available to the CPA Firm all relevant books and records and any work papers (including those of the
parties’ respective accountants, to the extent permitted by such accountants) relating to the Closing Balance Sheet, Final Closing Statement, and the Members’ Representative’s Objection and all other items reasonably requested by the
CPA Firm in connection therewith. 

 1.11.4 The Closing Balance Sheet, Net Working Capital, Tangible Net Worth, and PP&E, as
agreed to (or deemed to have been agreed to) between Parent and Members’ Representative or as determined by the CPA Firm, as applicable, shall be conclusive and binding on all of the parties hereto and shall be deemed the “Actual

(a) Upon completion of the calculation of the Actual Closing Balance Sheet, Actual Net Working Capital, Actual Tangible
Net Worth and Actual PP&E, in accordance with this Section 1.11, the Total Parent Shares shall be recalculated pursuant to Section 1.10.3 and the Excess Cash shall be recalculated pursuant to Section 1.10.4,
replacing all references to “Estimated PP&E” with “Actual PP&E”, “Estimated Net Working Capital” with “Actual Net Working Capital,” “Estimated Tangible Worth” with “Actual Tangible Net
Worth,” in each case, in each place where such reference appears, and the following adjustments (the “Purchase Price Adjustment”) made:

Sheet is greater than the Total Parent Shares as adjusted pursuant to Section 1.10.3 using the Estimated Net Working Capital, Estimated Tangible Net Worth, and Estimated PP&E shown on the Estimated Closing Balance Sheet, then Parent

 (ii) If the Total Parent Shares as adjusted pursuant to Section 1.10.3 using the Actual Net Working Capital, Actual Tangible Net Worth and Actual PP&E shown on the Actual Closing Balance
Sheet is less than the Total Parent Shares as adjusted pursuant to Section 1.10.3 using Estimated Net Working Capital, Estimated Tangible Net Worth and Estimated PP&E shown on the Estimated Closing Balance Sheet, then the Members

(iii) If the Excess Cash calculated pursuant to Section 1.10.4 using the Actual Net Working Capital, Actual

1.12 Transactions at Closing; Exchange of Certificates; Exchange Agent. 

1.12.1 Exchange Agent. Prior to the Effective Time, Parent shall designate its then transfer agent for Parent Shares to act as
agent (the “Exchange Agent”) for the ECS Members to receive the Per Unit Closing Date Merger Consideration to which the ECS Members are entitled at Closing. Prior to the Effective Time, Parent shall deposit with the Exchange Agent
the Per Unit Closing Date Merger Consideration to which the ECS Members are entitled at Closing. 
 1.12.2 Procedures for the
Issuance of Parent Shares and Option Consideration. 
 (a) Prior to receiving any portion of the Per Unit Closing
Date Merger Consideration or Option Consideration, each holder of record of Unit Equivalents, shall have delivered to Parent and, other than the Option Holders, the Exchange Agent (i) a properly completed and duly executed Letter of Transmittal
substantially in form of Exhibit F (each individually, a “Letter of Transmittal” and collectively, the “Letters of Transmittal”) and (ii) in the case of Common Units, the Certificates held of record by
such holder evidencing such holder’s Common Units issued and outstanding immediately prior to the Effective Time (or if any Certificate shall have been lost, stolen or destroyed, an affidavit of that fact and, if required by Parent, the
execution of an unsecured indemnity agreement reasonably acceptable to Parent by such holder against any claim that may be made against it on account of the alleged loss, theft or destruction of such Certificate). Upon surrender of a Letter of
Transmittal and, in the case of the ECS Members, a Certificate to the Exchange Agent (or alternatively, delivery of an affidavit and indemnity agreement reasonably acceptable to Parent), a Unit Equivalent Holder shall be entitled to receive in
exchange the consideration set forth in 

 
Section 1.9.1 or 1.15, as applicable. If any portion of the aggregate consideration to be paid as set forth herein is to be paid to a Person other than the Person in whose name the
Certificate so surrendered is registered in the case of a holder of Common Units or other than an Option Holder in the case of a holder of ECS Options, it shall be a condition of exchange that (x) such Certificate (in the case of Common Units)
or Notice of Assignment (in the case of ECS Options) shall be properly endorsed or otherwise in proper form for transfer and that the Person requesting such exchange shall pay any transfer or other Taxes required by reason of the exchange to a
Person other than the registered holder of such Certificate or establish to the reasonable satisfaction of the Exchange Agent and Parent that such Tax has been paid or is not applicable and (y) such Person execute and deliver to Parent a
certificate containing an appropriate representation regarding ownership and title to the Unit Equivalents represented by the applicable Certificate(s) or ECS Option and a corresponding unsecured indemnity agreement reasonably acceptable to Parent
against any claim that may be made against it on account of Parent’s payment of consideration to a Person other than the Person in whose name the surrendered Certificate is registered or a Person other than the Option Holder. As of the
Effective Time, each Certificate and ECS Option shall be deemed to represent only the right to receive, upon surrender of such Certificate or delivery of the Letter of Transmittal only, in the case of an ECS Option, in accordance with this
Section 1.12.2, the consideration into which the Unit Equivalents represented thereby shall have been converted pursuant to Section 1.9.1 or 1.15, as applicable. 

(b) If, after the Effective Time, Certificates are presented to the Exchange Agent, Parent or the Companies for any
reason, they shall be canceled and exchanged for the aggregate consideration set forth above in Section 1.9.1 represented by such Certificates. 
 (c) Subject to applicable Law, any portion of the Per Unit Closing Date Merger Consideration made available to the Exchange Agent pursuant to Section 1.12.2 that remains unclaimed by the Unit
Equivalent Holders one year after the Effective Time shall be returned to Parent and any Unit Equivalent Holder who has not exchanged such Unit Equivalents for the Per Unit Closing Date Merger Consideration in accordance with this
Section 1.12.2 prior to that time shall thereafter look only to Parent for payment of the Per Unit Closing Date Merger Consideration. 
 (d) None of Parent, the Companies or their respective Affiliates shall be liable to any former Unit Equivalent Holder for any Per Unit Closing Date Merger Consideration or Option Consideration properly
delivered to a public official pursuant to, and in accordance with, any applicable abandoned property, escheat or similar Law. If any Certificate has not been surrendered prior to the date that the consideration for such Unit Equivalents would
escheat, any Parent Shares represented thereby shall, to the extent permitted by applicable Law, automatically become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto. 

(e) Fractional Parent Shares. Notwithstanding any other provision of this Agreement to the contrary, no fractional Parent
Shares will be issued and any ECS Member entitled to receive a fractional Parent Share but for this Section 1.12.2(e) shall be entitled to receive a cash payment from Parent in lieu thereof, equal to such fraction multiplied by $13.

 1.13 Withholding. The Exchange Agent, Parent, ECS or the Surviving Entity (as appropriate) shall be entitled to deduct
and withhold from consideration otherwise payable pursuant to this Agreement to Unit Equivalent Holders such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or any provision of state,
local or foreign Tax Law. To the extent that amounts are so withheld, (i) such withheld amounts shall be treated for all purposes of this Agreement as having been paid to Unit Equivalent Holders and (ii) the Exchange Agent, Parent, ECS or
the Surviving Entity (as appropriate) shall provide to the Members’ Representative written notice of the amounts so deducted or withheld. 
 1.14 Further Action. If at any time after the Effective Time of the Merger, the Surviving Entity shall consider or be advised that any further assignments or assurances in law or otherwise are
necessary or desirable to vest, perfect or confirm, of record or otherwise, in the Surviving Entity, all rights, title and interests in all real estate and other property and all privileges, powers and franchises of ECS and Merger Subsidiary, then
the Surviving Entity and its proper officers and directors, in the name and on behalf of ECS and Merger Subsidiary, shall execute and deliver all such proper deeds, assignments and assurances in law and do all things commercially reasonable and
proper to vest, perfect or confirm title to such property or rights in the Surviving Entity and otherwise to carry out the purpose of this Agreement, and the proper officers and directors of the Surviving Entity are fully authorized in the name of
ECS and Merger Subsidiary or otherwise to take any and all such action. Any and all reasonable costs (including attorneys’ fees and expenses) incurred by the Surviving Entity resulting from performing actions authorized herein shall be paid
jointly and severally by the Members and Parent shall have the right to set-off such costs against amount otherwise payable to the Unit Equivalent Holders. 
 1.15 Options. ECS shall take all requisite action such that at or immediately prior to the Effective Time, each ECS Option shall be cancelled and without exercise or need for any other action on
behalf of any Option Holder other than the delivery of a properly completed and duly executed Letter of Transmittal, Parent shall pay or, at its expense, cause ECS to pay through ECS’s payroll system to each Option Holder an amount of cash in
immediately available funds equal to the Option Value, where the “Option Value” is equal to the 

 
product of (1) the excess, if any, of (A) the product of (x) the Per Unit Closing Date Merger Consideration multiplied by (y) $13, minus (B) the applicable exercise price
of such ECS Option, multiplied by (2) the number of Common Units issuable upon the exercise of such ECS Option in full immediately prior to the Effective Time.

 In order to induce Parent to enter into and perform this Agreement and to consummate the Contemplated Transactions, ECS and the Members hereby jointly and severally represent and warrant to Parent that

obligations to the respective Company and, subject only to consistently recorded reserves for bad debts established as of a date prior to the Closing Date in a manner consistent with past practice, have been, or will be, collected or are, or will
be, collectible in the aggregate recorded amounts thereof in accordance with their terms (and in no event later than the

specific amount of Backlog attributable to each such Contractual Obligation, together with a description of the remaining work to be performed under each such uncompleted Contractual Obligation. The Backlog amounts set forth on Schedule 2.11,
both individually and in the aggregate, constitute the Companies’ best reasonable estimates of such amounts. Immediately following the date hereof, since the Most Recent Balance Sheet Date, the aggregate amount of Backlog, as adjusted for
reductions resulting from the performance of work in the Ordinary Course of Business pursuant to such Contractual Obligations has not been reduced by 5% or more. As of the Closing Date, since the Most Recent Financials Balance Sheet Date, except as

Contained in the Data Room are true, accurate and complete copies of each written Contractual Obligation listed on Schedule 2.11, in each case, as amended or otherwise modified and in effect. 

2.12 Real Property. 
 2.12.1 The Companies own no real property and do not have any right, title or interest in and to any real property except as specifically set forth on Schedule 2.12. Schedule 2.12 describes
each leasehold interest in real property leased, subleased by, licensed or with respect to which a right to use or occupy has been granted to or by a Company (such leased real property is referred to as the “Real Property”), and
specifies the lessor(s) of such Real Property, and identifies each lease or any other Contractual Obligation under which such Real Property is leased by any of the Companies (the “Real Property Leases”). Except as described on
Schedule 2.12 there are no written or oral subleases, licenses, concessions, occupancy agreements or other Contractual Obligations granting to any other Person the right of use or occupancy of the Real Property, and there is no Person (other
than the Companies and/or any lessee(s) of the Real Property specifically identified on Schedule 2.12) in possession of the Real Property. With respect to each Real Property Lease that is a sublease: (a) to ECS’s Knowledge, the
representations and warranties set forth in Sections 2.19.2 and 2.19.3 are true and correct with respect to the underlying lease(s) (the “Underlying Leases”); and (b) Schedule 2.12 describes each of the Underlying
Leases, if any. The Companies have valid leasehold interests in and to the Real Property and any and all Facilities located thereon, free and clear of all Encumbrances except for Permitted Encumbrances and the Encumbrances set forth on Schedule
2.12. 
 2.12.2 The Real Property Leases do not impose restrictions on any portion of any Business that interfere with such
Business. No Company is obligated to pay any leasing or real estate brokerage commission as a result of the Contemplated Transactions. There is no pending or, to ECS’s Knowledge, threatened eminent domain taking affecting any of the Real
Property. Contained in the Data Room are true, correct and complete copies of all of the Real Property Leases and Underlying Leases, including all amendments, modifications, guaranties, notices, memoranda of lease, estoppel certificates, instruments
of title, plats, surveys, title abstracts, title insurance policies, and subordinations, non-disturbance and attornment agreements related thereto. No consents or approvals are required to be obtained under the Real Property Leases and/or the
Underlying Leases in connection with the Contemplated Transactions, including from the landlord(s) thereunder, or if such consents or approvals are required, (i) they have been obtained and copies of which are contained in the Data Room,
(ii) in the case of third party lenders to Affiliates of any Member of the Company, that are disclosed on Schedule 2.5(b), or (ii) in the case of third party landlord(s) that are not Affiliates of any Member or the Company, that are
disclosed on Schedule 2.5(b). 
 2.12.3 No Facility currently existing on the Real Property encroaches upon, and no
Facility under construction on the Real Property will encroach upon, the real property or easement estate of any other Person. No facility of any other Person encroaches 

 
upon the Real Property or any easement estate appurtenant to the Real Property. Each Facility is supplied with utilities and other services (including gas, electricity, water, drainage, sanitary
sewer, storm sewer, fire protection and telephone) necessary for the operation of such Facility as the same is currently operated or proposed to be operated, and all installation charges for such utilities and other services have been fully paid,
and all service charges due prior to the Closing Date for such utilities and other services have been paid when due. Each Facility is in good repair and operating condition, normal wear and tear excepted, with all required maintenance having been
regularly performed and, to ECS’s Knowledge, free from structural defects. Each parcel of Real Property abuts on, and has direct vehicular access to, a public road, or has access to a public road via a permanent, irrevocable appurtenant
easement benefiting the parcel of Real Property, in each case, to the extent necessary for the conduct of the Businesses. 

2.12.4 All Permits necessary in connection with the construction upon, and present use and operation of, the Real Property and the lawful
occupancy thereof have been issued by the appropriate Governmental Authorities. Except as set forth in Schedule 2.12, the current use of the Real Property is in accordance with the certificates of occupancy relating thereto and the terms of
any such Permits. All such Permits will continue in full force and effect immediately after giving effect to the Contemplated Transactions. The Real Property and its current use, occupancy and operation by any of the Companies and the Facilities
located thereon do not (a) constitute a nonconforming use under any applicable building, zoning, subdivision or other land use or similar Legal Requirement, or (b) otherwise violate or conflict with any covenant, condition, restriction or
other Contractual Obligation, including the requirements of any applicable Encumbrances thereto. Except as set forth on Schedule 2.12, none of the Companies nor any Predecessor thereof: (x) is in violation of any Legal Requirement
relating to Real Property, including setback requirements, zoning restrictions and ordinances, building, life, access, safety, health and fire codes and ordinances affecting the Real Property; (y) has received notice of any eminent domain,
condemnation or similar proceeding pending or, to ECS’s Knowledge, threatened, or any Governmental Order relating thereto; or (z) has received notice of any Taxes or assessments (other than ordinary real estate Taxes pending and not yet
due and payable) against the Real Property or any contingencies existing under which any assessment for real estate Taxes may be retroactively filed against the Real Property. The Real Property is not located within any flood plain (except in the
case of Real Property leased by any Company within a flood plain where such Company’s use is permitted by such Company under applicable Legal Requirements) or subject to any similar type of restriction for which any Permits necessary to the use
thereof have not been obtained. 
 2.13 Tangible Personal Property. Except as set forth on Schedule 2.13, all of
the fixtures and other improvements to the Real Property included in the Assets (including any Facilities) and all of the tangible personal property other than inventory included in the Assets (the “Equipment”) (a) are adequate
and suitable for their present and intended uses, (b) are in good working order, operating condition and state of repair, reasonable wear and tear excepted, (c) have no defects (whether patent or latent) that interfere with their intended
use and (d) have been maintained in all material respects in accordance with the commercially reasonable standards of any manufacturer or any other governmental or regulatory entities. 

2.14 Intellectual Property. 
 2.14.1 Schedule 2.14 identifies all Intellectual Property owned or used by the Companies in their respective Businesses, including all Intellectual Property with respect to Company Technology, and
lists: (a) all registered Intellectual Property which has been issued to or is otherwise owned by the Companies or that relates to or is otherwise used by the Companies in the Businesses; and (b) each Contractual Obligation pursuant to
which any of the Companies have granted or have been granted rights to any Intellectual Property or to which any of them is otherwise bound to any third party, excluding however, “shrink wrap,” “click through” or other standard
agreements for commercially available, unmodified third party Software in each case having a purchase price of $2,500 or less (“Commercial Software”). Except as set forth on Schedule 2.14, No Company has any pending
application for registration which such Company has made or otherwise owns with respect to any Intellectual Property. True, accurate and complete copies of all such Contractual Obligations, as amended or otherwise modified and in effect, are
contained in the Data Room, together with true, accurate and complete copies of all other written documentation evidencing ownership and prosecution (if applicable) of each such item. Except as set forth in Schedule 2.14, all such Contractual
Obligations are in full force and effect. Except as set forth in Schedule 2.14, to ECS’s Knowledge, there does not exist any claim, allegation, or basis for any claim or allegation, that any Intellectual Property owned or otherwise used
by the Companies is invalid or unenforceable or that the Companies’ rights with respect thereto are subject to claims or defenses that would impair or preclude enforcement of such rights, including misuse, laches, acquiescence, statute of
limitations, abandonment or fraudulent registration. Schedule 2.14 also identifies each trade name, trade dress and unregistered trademark or service mark used by any of the Companies or in connection with the Businesses or the Company
Technology. 
 2.14.2 The Companies either individually or collectively are the sole owners of all rights, title and interest in
and to all Intellectual Property with respect to, or have the right to use as specified on Schedule 2.14, all the Company Technology free and clear of any Encumbrances (other than Permitted Encumbrances). Each Company has the right to use all
other Technology and Intellectual Property used in its respective Businesses as currently conducted and as currently contemplated to be conducted in the future. The Intellectual Property identified on Schedule 2.14 constitutes all
Intellectual Property that is used in the Businesses and all Intellectual Property necessary for the conduct of the Businesses as currently conducted and as contemplated to be conducted in the future. Except as set forth on Schedule 2.14, no
Member has any ownership or other interest in any Intellectual Property used in the Businesses. 

 2.14.3 No Company nor any Predecessor thereof (a) has, nor has the conduct of the
Businesses, interfered with, infringed upon, misappropriated, diluted or otherwise violated or come into conflict with any Intellectual Property rights of third parties or (b) has received any charge, complaint, claim, demand, or notice
alleging any such interference, infringement, misappropriation, dilution or other violation or conflict (including any claim that it must obtain a license or refrain from using any Intellectual Property rights of any third party in connection with
the conduct of the Businesses or the use of the Company Technology, or, with respect to any other Technology used in the Businesses, that it must obtain a license that it does not already possess or refrain from using same). To ECS’s Knowledge,
there does not exist any basis for any such claim or allegation. To ECS’s Knowledge, no third party has interfered with, infringed upon, misappropriated, diluted or otherwise violated or come into conflict with any Company Technology or any of
the Companies’ other Intellectual Property. Except as set forth in Schedule 2.14, no claim or legal proceeding involving any Intellectual Property by or against the Companies is pending or, to ECS’s Knowledge, has been threatened.
Except as otherwise specified on Schedule 2.14 and except for licenses to Commercial Software, no Company is bound by any Contractual Obligation containing any covenant or other provision relating to Intellectual Property that in any way
limits or restricts the Companies’ ability to use, exploit, assert, or enforce any of their Intellectual Property or conduct their Businesses as currently conducted and as currently contemplated to be conducted in the future. 

2.14.4 Except for that Software described on Schedule 2.14, the Companies’ Software constitutes all the Software used in or
necessary to conduct the Businesses as currently conducted by the Companies and as contemplated to be conducted in the future. 

2.14.5 Except as set forth in Schedule 2.14, with respect to each item of the Company Technology or other Technology or
Intellectual Property used in the Businesses:

to such item, or have the valid and Enforceable right to use same, free and clear of any Encumbrance (other than Permitted Encumbrances); 
 (b) to ECS’s Knowledge, such item is not subject to any outstanding Governmental Order, and no Action is pending or threatened, which challenges the legality, validity, enforceability, use or
ownership of such item, nor, to ECS’s Knowledge, is there any basis for such a challenge; and 
 (c) no
Company has agreed to nor otherwise has a Contractual Obligation to indemnify any Person for or against any interference, infringement, misappropriation or other conflict with respect to such item. 

2.14.6 Schedule 2.14 identifies each item of Technology that any Person other than the Companies owns and that is used by any of
the Companies pursuant to any license, sublicense or other Contractual Obligation except for agreements for Commercial Software (the “Licenses”). Except as disclosed on Schedule 2.14 and except for the Licenses, there are no
royalties or other amounts payable for the use of any such Technology. Contained in the Data Room are true, accurate and complete copies of all of the Licenses, in each case, as amended or otherwise modified and in effect. Except as disclosed on
Schedule 2.14, each License is in full force and effect, is valid and Enforceable and no party thereto is in breach of any of the terms thereof. With respect to each such item identified on Schedule 2.14: (a) to ECS’s
Knowledge, such item is not subject to any outstanding Governmental Order, and no Action is pending or threatened which challenges the legality, validity or enforceability of such item and (b) no Company has granted any sublicense or similar

 2.14.7 The Companies have taken reasonable and customary measures and
precautions necessary to protect and maintain the confidentiality of all Trade Secrets in which any of the Companies have any right, title or interest and otherwise to maintain and protect all such Trade Secrets. All current employees, consultants
and independent contractors of the Companies who are or have been involved in, or who have contributed to, the creation or development of the Companies’ owned intellectual property have executed and delivered to such Company an agreement
(containing, except as disclosed on Schedule 2.14, no exceptions to or exclusions from the scope of its coverage) that protects proprietary information and assigns to such Company any and all such Intellectual Property or have validly waived
or otherwise conveyed the benefit of any rights therein to such Company. Except as disclosed on Schedule 2.14, none of the Companies own any Software or possess any source code for any licensed Company Software.

 2.34.1 The Parent Shares that may be issued in connection with this Agreement are being acquired by the Members for their own accounts, for investment and not with a view to, or intention of, distribution

2.34.2 Each Member is an “accredited investor” as defined in Rule 501(a) under the 1933 Act, as amended by the Dodd-Frank Wall
Street Reform and Consumer Protection Act of 2010, possessing such knowledge and experience in financial and business matters and sophistication, as an investor, adequate for the evaluation of the merits and risks of its investment in the Parent
Shares and to make an informed investment decision. 

 2.34.3 Each Member has had an opportunity to ask questions and receive answers concerning
Parent and the Parent Shares and has had full access to such other information concerning Parent and the Parent Shares as such Member has requested or which has been filed by Parent with the SEC.

acknowledges that the Parent Shares are “restricted securities” as defined by Rule 144 promulgated under the 1933 Act, are not registered under the 1933 Act or any applicable state securities laws and are being issued by Parent to the
Members in reliance upon the Section 4(2) private placement exemption contained in the 1933 Act. 
 2.34.6 Each Member
understands that he or it must bear the economic risk of his or its acquisition of the Parent Shares for an indefinite period of time because (i) the acquisition of Parent Shares pursuant to this Agreement has not been registered under the 1933
Act and applicable state securities laws; and (ii) the Parent Shares may therefore not be sold, transferred, pledged, or otherwise disposed of unless subsequently so registered or, in the opinion of counsel (reasonably satisfactory to Parent),
registration under the 1933 Act or any applicable state securities laws is not required. 
 2.34.7 Legends. It is understood
that the certificates evidencing the Parent Shares may bear one or all of the following legends:

(b) “These securities are additionally subject to the transfer restrictions set forth in that certain
Agreement and Plan of Merger, dated November 16, 2010, as amended or otherwise modified (the “Agreement”), by and among MasTec, Inc., ECS Acquisition Merger Subsidiary I, Inc., ECS Acquisition Merger Subsidiary II, LLC, EC

or engaging in such discussion or negotiation. 
 4.4.3 The Companies and Members will, and will cause their Representatives to,
immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Person(s) conducted heretofore with respect to any Acquisition Proposal. In addition, the Companies shall promptly request that each Person

Neither ECS nor the Members shall, and each of which shall cause the Subsidiaries not to, release any third party from, or waive any provision of, any confidentiality or standstill agreement to which any Company or Member is a party. ECS and the
Members agree that they will take the necessary steps to promptly inform their Representatives of the obligations undertaken by ECS and Members in this Section 4.4. 

4.5 Bank Accounts; Powers of Attorney. As of the Closing, to the extent requested by Parent, ECS and the Members shall cause
Parent’s designees to be added, and the Companies’ respective designees to be removed, as signatories with respect to each of the Companies’ respective bank accounts and to terminate any powers of attorney. 

4.6 Notice. Between the date hereof and the Closing Date within thirty (30) days of Parent’s request (such request not
to be made more than two (2) times in any calendar year) and promptly after Parent’s exercise of the Merger Option, the Members’ Representative will notify Parent in writing (where appropriate and only with respect to matters
occurring after the date hereof, through updates to the Disclosure Schedules) of, and contemporaneously will provide Parent with and upload to the Data Room true, accurate and complete copies of any and all information or documents relating to any
event, transaction or circumstance, that existed or occurred on, prior to or after the date of this Agreement, as soon as practicable after it becomes known to ECS or any Member, that causes or will cause any representation, warranty, covenant or
agreement of ECS and/or the Members under this Agreement to be breached, that renders or will render untrue any representation or warranty of ECS and/or the Members contained in this Agreement as if the same were made on or as of the date of such
event, transaction or circumstance, or that make the timely satisfaction of any condition to Closing impossible or unlikely. Both ECS and the Members, on the one hand, and Parent, on the other, shall have the right until the Closing Date to amend or
supplement their respective Disclosure Schedules to the representation and warranties in Section 2 and 3. No notice (or updates to Disclosure Schedules) given pursuant to this Section 4.6 shall have any effect on the
representations and warranties made as of the date of this Agreement or any covenants or agreements contained in this Agreement for purposes of determining satisfaction of any condition, whether a breach or default has occurred, or the termination
or indemnification rights of the parties provided by this Agreement or otherwise. 
 4.7 Consultation. To the extent
permitted by applicable Law, (i) during the Pre-Closing Period, ECS and the Members will consult with management of Parent with a view to informing them as to the operation and management of the Companies, and (ii) and during the Option
Pre-Closing Period, ECS will cause its management, and will cause the management of the Companies to, participate in monthly operational reviews with the management of Parent. 
 4.8 Interim Financial Statements. During the Pre-Closing Period, ECS and the Members shall cause the Companies to provide Parent with the “Audited Financials,” “Unaudited
Quarterly Financials” and “Unaudited Monthly Financials,” in each case as such term is defined in the New Operating Agreement and subject to the terms and conditions specified in the New Operating Agreement for such
financials; provided however, that for the purposes of this Agreement, ECS and the Members shall have: (i) 120 days after the end of each fiscal year to deliver the Audited Financials, (ii) 30 days after the end of each calendar month to
deliver the Unaudited Monthly Financials, provided further that for the purposes of this Agreement the Unaudited Monthly Financials shall be required for every calendar month and shall also be required to contain unaudited consolidated statements of
cash flows of the Companies for the period from the beginning of the current fiscal year to the end of such month, in each case, in addition to and in compliance with all of the other terms and conditions that apply to such Unaudited Monthly
Financials as set forth in the New Operating Agreement and (iii) 30 days after the end of each fiscal quarter to deliver the Unaudited Quarterly Financials; provided further that for the purposes of this Agreement Unaudited Quarterly Financials
shall be required for every fiscal year quarter. Upon delivery of the foregoing financial statements to Parent, the representations and warranties set forth in Section 2.6 and other financial statement representations and warranties set
forth herein shall be deemed to have been made as to such financial statements to the extent that such financial statements are the Most Recent Financials as of the Closing Date. 

4.9 Environmental Review 
 4.9.1 Parent, at its sole cost and expense, may undertake “Phase I” environmental site assessments (the “Phase I ESA(s)”) of any Asset that is real property. Each Phase I ESA
that Parent elects to undertake shall be conducted by a reputable environmental consultant with appropriate licenses, certificates, experience and training selected by the Parent (the “Environmental Consultant”). The Environmental
Consultant shall conduct the Phase I ESAs in accordance with the ASTM E1527-00 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process (as such practice may have been updated or revised as of

 
the date hereof, the “ASTM Phase I ESA Standard”) and may include such non-scope considerations reasonably specified by the Parent. The Phase I ESAs, however, shall not include
testing of any environmental medium, or any materials, of any structure on any real property without the express written approval of ECS, which approval shall not be unreasonably withheld. Notwithstanding the foregoing sentence, any such testing of
any environmental medium, or materials, of any structure on any real property during any Phase I ESA shall not unreasonably interfere with the ability of the Companies to conduct their business or result in any material damage to any such structure.

 4.9.2 Should any Phase I ESA reveal a “recognized environmental condition,” as defined in the ASTM Phase I ESA
Standard, for which the Environmental Consultant recommends a Phase II ESA (as defined below), then Parent may cause the Environmental Consultant to undertake a reasonable and appropriate subsurface investigation of any such recognized environmental
condition at any such real property in a “Phase II” environmental site assessment (the “Phase II ESA(s)”) in accordance with ASTM E1903-97 (2002) (as such practice may have been updated or revised as of the date
hereof, the “ASTM Phase II ESA Standard”). The Environmental Consultant shall prepare a separate scope of work and cost estimate for each Phase II ESA of each real property that Parent reasonably deems necessary. The performance of
such Phase II ESAs shall not unreasonably interfere with the ability of the Companies to conduct their business. 
 4.9.3 After
the conclusion of any Phase I or Phase II ESAs, as set forth above, Parent will be responsible to restore the real property to its original condition and repair any damage resulting from such Phase I or Phase II ESA work. 

4.10 Employee Benefit Plans 
 4.10.1 Within 90 days of the date hereof: (i) all assets that are attributable to current or former employees (or the beneficiaries of such current or former employees) of an employer participating
in the ECS 401K Plan other than the Companies, shall be spun off into a separate employee benefit plan that is: (x) qualified under Section 401(a) of the Code and (y) sponsored by the employer of such current or former employee or
employees and (ii) the Participating Employers Addendum to the Adoption Agreement of the ECS 401K Plan shall be amended to remove ECSD as a participating employer in the ECS 401K Plan. 

4.10.2 ECS and the Members acknowledge that following the date hereof, the Companies and Parent may be members of a single controlled
group of corporations under Section 414(b) of the Code or trades or businesses which are under common control under Section 414(c) of the Code. Accordingly, each Member and ECS hereby agrees with Parent that such Member and ECS and their
respective Representatives will not, and that such Member will cause its respective Affiliates not to, at any time on or after the date hereof, directly or indirectly, without the prior written consent of the Parent to (a) perform any action,
including, but not limited to significantly changing the coverage of the ECS 401K Plan, that would cause the transition rule set forth in Section 410(b)(6)(C)(i) of the Code to no longer apply to any plans intended to be qualified under
Section 401(a) of the Code that are maintained by ECS or Parent during the transition period set forth in Section 410(b)(6)(C)(ii) of the Code, or (b) make any election for purposes of determining highly compensated employees under
the ECS 401K Plan that would be inconsistent with any election made by Parent with respect to any plan maintained by Parent that is intended to be qualified under Section 401(a) of the Code, including, but not limited to the top-paid group
election or the calendar year data election. 
 4.10.3 Each Member and ECS and their respective Representatives shall, or as
applicable shall cause their respective Affiliates to, at all times on and after the date hereof, directly or indirectly, (a) operate the ECS 401K Plan in a manner that satisfies the nondiscrimination testing requirements and any other
requirements set forth in the Code and the Treasury Regulations thereunder to insure the continued qualification of the ECS 401K Plan under Section 401(a) of the Code, and (b) following the transition period forth in
Section 410(b)(6)(C)(ii) of the Code that results from the Contemplated Transactions, provide Parent with any information reasonably requested by Parent for purposes of determining whether the employees of ECS participating in the ECS 401K Plan
satisfy the coverage requirements of Section 410(b) of the Code and to the extent ECS fails to satisfy the coverage requirements of Section 410(b) of the Code when tested with the employees of Parent as members of a single controlled group
of corporations under Section 414(b) of the Code or trades or businesses which are under common control under Section 414(c) of the Code, cause ECS to comply with Parent’s reasonable instructions to insure that the ECS 401K Plan
satisfies the nondiscrimination testing requirements, including, modifying the amount of any employer contributions under the ECS 401K Plan, and any other requirements Parent reasonably deems necessary to ensure the continued qualification of the
ECS 401K Plan under Section 401(a) of the Code. 
 4.11 Employment Agreements. Each Member and Parent and their
respective Representatives will enter or has entered into amendments, or as applicable will cause or has caused their respective Affiliates to enter into amendments, to the employment or service agreements entered into between ECS and each of James
Haunty, Robert Dunbar, Chuck Desrosiers, Jon Maslonka, Justin Campbell, Brian Bratton, and Brian Smaistrla and the employment agreements entered into between T&D and William Wright and EEG and Sid Strauss, substantially in the form set forth on
Exhibit J, within sixty (60) days of the date hereof. 
 4.12 Health and Life Insurance Plans. Prior to the
Effective Time, all employees of an employer, other than the Companies, must cease participating in any “welfare benefit plan” (within the meaning of Section 3(1) of ERISA) or life insurance plan sponsored or maintained by any
Company. 

	5.	POST-CLOSING COVENANTS 

 5.1
Confidentiality. 
 5.1.1 The Members acknowledge that the success of the Companies after the Closing Date depends upon
the continued preservation of the confidentiality of certain information possessed by the Members, that the preservation of the confidentiality of such information by the Members is an essential premise of the bargain between the parties hereto, and
that Parent would be unwilling to enter into this Agreement in the absence of this Section 5.1.1. Accordingly, each Member hereby agrees with Parent that such Member and its Representatives will not, and that such Member will cause its
Affiliates not to, at any time on or after the Closing Date, directly or indirectly, without the prior written consent of Parent, disclose or use, any confidential or proprietary information involving or relating to the Businesses, the Companies or
Buyer, including (1) customer and supplier information, including lists of names and addresses of customers and suppliers of the Companies, Buyer or any of their respective Affiliates, (2) business plans and strategies, compensation plans,
compensation information, sales plans and strategies, pricing and other terms applicable to transactions between existing and prospective customers, suppliers or business associates, (3) market research and databases, sources of leads and

documents provided by Buyer, (6) all information posted in the Data Room to the extent such information was produced by or on behalf of any of the Companies and (7) all information that would be a trade secret under any applicable Law;
provided, however, that the information subject to the foregoing provisions of this sentence will not include any information generally available to, or known by, the public (other than as a result of disclosure in violation hereof or
any other agreement); and provided, further, that the provisions of this Section 5.1.1 will not prohibit any retention of copies of records or disclosure (a) required by any applicable Legal Requirement so long as
reasonable prior notice is given to Parent of such disclosure and a reasonable opportunity is afforded to Parent to contest the same or (b) made in connection with the enforcement of any right or remedy relating to, or the performance of any
obligation arising under, this Agreement or the Contemplated Transactions. Each Member agrees that it will be responsible for any breach or violation of the provisions of this Section 5.1.1 by any of its Representatives and Affiliates.

 5.1.2 Notwithstanding the foregoing, each Member, and each of their Representatives may disclose to any and all Persons,
without limitation of any kind, the Tax treatment and Tax structure of the Contemplated Transactions and all materials of any kind (including opinions or other Tax analyses) that are provided to the Members relating to such Tax treatment and Tax
structure. 
 5.2 Restrictive Covenants. 
 5.2.1 Noncompetition. Each Member (other than Strauss) on his or its own behalf and on behalf of each of his or its Affiliates, covenants that from the Closing Date through the later of the
seven-year anniversary of the Closing Date or 24 months after such Member’s termination of employment with any of the Companies, Parent, the Surviving Entity or any of their respective Affiliates (provided that a transfer of a Member’s
employment between such entities shall not be deemed a termination of employment) , neither he or it nor his or its Affiliates will for his, its or their own account, jointly with another, or for or on behalf of any Person, directly or indirectly,
anywhere within the United States of America, Canada, or Mexico (the “Territory”): 
 (a) own,
manage or control, or become engaged or serve as a shareholder, bondholder, creditor, officer, director, partner, member, employee, agent, consultant, advisor, or representative of any Person, business or enterprise that competes directly or
indirectly with the Companies in the Businesses (a “Competitive Business”) other than Parent, the Surviving Entity or any of the Companies; provided, however, that each Member and his or its Affiliates may passively
hold up to 1% of the outstanding publicly-traded securities of a Person engaged in a Competitive Business for investment purposes only and any amount of any class of securities of Parent; 

(b) recruit, induce, solicit, or employ, or in any manner attempt to recruit, induce, solicit, or employ, any Person that
is at such time, or during the previous two year period was an employee, independent contractor, or consultant of any Company; 
 (c) solicit any Person that is at such time, or during the previous two-year period was, (i) a customer, supplier or business associate of any Company, or (ii) a Person from whom any Company
solicited business or with whom any Company discussed a potential business relationship, in each case, for the purpose of offering or providing services or products which are competitive with services or products provided by any Company in the
Businesses; 
 (d) cause or seek to cause to be terminated or adversely affected, or otherwise interfere with,
any agreement or arrangement of any kind to which any Company is a party or from which it benefits; or 
 (e)
seek to interfere with or adversely affect the ongoing relationships between any Company, on the one hand, and its suppliers, customers and professional and business contacts, on the other. 

 5.2.2 Acknowledgement. Each Member acknowledges that the Companies conduct the
Businesses throughout the Territory; that they each provide services, directly or indirectly, to the Companies throughout the Territory; and that they each are intimately familiar with the Companies’ trade secrets, confidential information, and
employee, customer and supplier relationships. Accordingly, each Member agrees that the Territory, time limitation, and scope of restrictions set forth in this Section 5.2 are reasonable and necessary to protect the legitimate business
interests of Parent. Each Member agrees that any reduction to the Territory, time limitation, or scope of restrictions set forth herein would seriously undermine the efficacy of this Section 5.2 and the protections that it is intended to
provide. Each Member acknowledges and agrees that the covenants contained in this Sections 5.1 and 5.2 are essential elements of this Agreement and that but for these covenants Parent would not have agreed to consummate the Merger.
Each Member further expressly agrees and acknowledges that (a) the confidentiality, nonsolicitation and non-competition covenants contained in this Agreement (i) are reasonable and necessary for the protection of Parent with respect to the
covenants’ respective stated purposes, time, scope and geographic area, and are supported by adequate consideration; (ii) are necessary for the protection of Parent’s legitimate business interests, including the protection of trade
secrets, goodwill, and relationships with customers and suppliers purchased by Parent pursuant to this Agreement; and (iii) are not unduly restrictive of any rights of the Members; and (b) each Member has sufficient employment or
business alternatives and sufficient assets, taking into account the consideration received and to be received by such Member, such that such Member does not have to compete with any Company or impermissibly use any Company’s confidential,
proprietary, or trade secret information described in this Agreement in order to earn a living. The existence of any claim or cause of action against Parent by any Member, whether predicated on Parent’s breach of this Agreement or otherwise,
shall not constitute a defense to the enforcement by Parent of the covenants contained in Sections 5.1 and 5.2 . 

5.2.3 Injunction. The Members agree that a violation of the terms, provisions, obligations, duties and conditions described in
this Agreement will cause irreparable damage to Parent for which money damages or other legal remedies would not be an adequate remedy. Accordingly, each Member acknowledges and hereby agrees that in the event of any breach or threatened breach by
any Member of any of their covenants or obligations set forth in this Sections 5.1 and 5.2, Parent shall be entitled, in any court in the United States or otherwise having jurisdiction, to an injunction or injunctions, without the
posting of any bond, to prevent or restrain breaches or threatened breaches of Sections 5.1 and 5.2, and to specifically enforce the terms and provisions of this Sections 5.1 and 5.2 to prevent breaches or threatened
breaches of, or to enforce compliance with, the covenants and obligations of this Sections 5.1 and 5.2. Each Member hereby agrees not to challenge the enforceability of the restrictive covenants contained in Sections 5.1 and
5.2 or raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of Sections 5.1 and 5.2, and to specifically enforce the terms and provisions
of Sections 5.1 and 5.2 to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of each Member under this Sections 5.1 and 5.2. The Members further agree that
(x) by seeking the remedies provided for in this Section 5.2.3, Parent shall not in any respect waive its right to seek any other form of relief that may be available under this Agreement (including monetary damages), and
(y) nothing set forth in this Section 5.2.3 shall require Parent to institute any Action for (or limit Parent’s right to institute any Action for) specific performance under this Section 5.2.3 prior or as a
condition to exercising any rights under Section 1.9.2(h), Section 9 or otherwise, nor shall the commencement of any Action pursuant to this Section 5.2.3 or anything set forth in this Section 5.2.3
restrict or limit Parent’s right to pursue any other remedies under this Agreement or otherwise that may be available to Parent thereafter. The parties acknowledge and agree that, in the event Parent institutes an Action to enforce the
restrictive covenants set forth in this Sections 5.1 and 5.2 in a forum other than one of the forum identified in Section 11.15, Parent may elect to pursue all other remedies (including damages) available to it based on the
same set of facts and circumstances in the forum chosen for the injunctive relief Action or it may elect to pursue its damages and other non-injunction remedies in a forum set forth in Section 11.15 and in no event shall Parent’s
election be deemed a waiver of its rights or remedies or allow any Member to institute an action or assert claims or counterclaims in any forum except as specified in Section 11.15. 

5.2.4 Severability. If any covenant or restriction contained in Sections 5.1 and 5.2, or any part thereof, is
hereafter construed or found to be invalid or unenforceable in part or in whole, this shall not effect the remainder of the covenants or restrictions, which shall be given full effect, without regard to the invalid portions, and any court having
jurisdiction shall enforce such invalid covenant or restriction to the maximum extent possible under applicable Law, including the maximum permissible time, scope and geographic area for such covenant or restriction. 

5.3 Cooperation Regarding Financial Statements. The Members shall use their best reasonable efforts to assist and cooperate
with the efforts of Parent and its accountants and auditors to prepare and audit any financial statements (including pro forma financial statements) that Parent will be required to prepare, file or furnish pursuant to any applicable securities
laws or exchange requirements, including the 1933 Act, the Exchange Act, the rules and regulations of the SEC promulgated thereunder, and any rules or regulations of the New York Stock Exchange or other stock exchange, or under any other
applicable Laws. 
 5.4 Litigation Support. If and for so long as Parent or any Company is actively contesting or
defending against any Action in connection with any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act or transaction existing or occurring on or prior to the Closing Date
involving any Company or any Business, the Members will cooperate in the contest or defense and provide such testimony as may be reasonably necessary in connection with the contest or defense, at the cost and expense of Parent (unless and to the
extent Parent is entitled to indemnification therefor hereunder, in which event such costs and expenses shall be borne jointly and severally by the Members). 

 5.5 Restrictions on Transfer of Parent Shares. 

(a) The Members will not, and the Indirect Members will cause the Entity Members not to, sell, transfer, pledge, assign,
hypothecate or otherwise encumber, dispose of or hedge (whether by the purchase of put options, short selling Parent Shares or otherwise) any Parent Shares or enter into any agreement to do any of the foregoing (the “Transfer
Restrictions”) at any time from the date hereof until the date on which the Transfer Restrictions on the Parent Shares have lapsed in accordance with the provisions of Subsection 5.5(b); provided however, that if any Non-Entity
Member receives Parent Shares pursuant to this Agreement, such Non-Entity Member may, subject to Parent’s prior written consent, which consent may not be unreasonably withheld, transfer such Parent Shares to a Member of the Immediate Family of
such Non-Entity Member as a result of his death or in connection with bona fide estate planning purposes. 
 (b)
The Transfer Restrictions shall lapse as follows: 
 (i) The Transfer Restrictions with respect to 25% of the
Parent Shares issued to each ECS Member shall lapse on the first anniversary of the Closing Date; 
 (ii) The
Transfer Restrictions with respect to an additional 25% of the Parent Shares issued to each ECS Member shall lapse on the second anniversary of the Closing Date; and 

(iii) The Transfer Restrictions with respect to the remaining 50% of the Parent Shares issued to each ECS Member shall
lapse on the third anniversary of the Closing Date. 
 5.6 Member Suretyship Obligations. From and after Closing, the
Companies shall not, and Parent shall cause the Companies not to, incur or permit to be issued any additional bonds, letters of credit or other obligations that are subject to the Member Suretyship Obligations. For purposes of this
Section 5.6, “Member Suretyship Obligation” means any obligation by which a Member is liable, contingently or otherwise, as obligor, guarantor or otherwise, or with respect to which obligation a Member assures a creditor
against loss (including contingent reimbursement or indemnification obligations with respect to letters of credit or surety bonds), in each case, to the issuer or co-issuer of any surety bond or letter of credit issued at the request of any of the
Companies. If the Member Suretyship Obligations are not released at or prior to Closing, the Companies and Parent will indemnify the Members from any Member liability related to or arising out of a Member Suretyship Obligation to the extent such
Member liability results from an action or an event that occurred after the Closing, and following Closing shall use commercially reasonable efforts to have the Member Suretyship Obligation released.

contained in such representation or warranty which has the effect of making such representation and warranty less likely to be breached (as if such word or words were deleted from such representation and warranty). 

Notwithstanding anything contained herein to the contrary, for purposes of determining whether there has been a breach and the amount of
any Losses that are the subject matter of a claim for indemnification or reimbursement hereunder, each representation and warranty in this Agreement and schedules and exhibits hereto shall be read without regard and without giving effect to any
Materiality Qualifier contained in such representation or warranty which has the effect of making such representation and warranty less likely to be breached (as if such word or words were deleted from such representation and warranty).

indemnify and hold harmless the Members and their Affiliates, and the Representatives and Affiliates of each of the foregoing Persons (each, a “Company Indemnified Person”), from, against and in respect of any and all Losses

Section 9 related thereto shall survive until such claim is finally and fully resolved in accordance with this Agreement. 
 Claims for indemnification pursuant to any other provision of Sections 9.1 and 9.2 or pursuant to Section 10 are not subject to the limitations set forth in this
Section 9.3. 
 9.4 Indemnification Limits. 

9.4.1 The Members shall not be liable for any indemnification obligations under this Agreement with respect to, or to hold any Parent
Indemnified Persons harmless from, and Parent shall not be liable for any indemnification obligations under this Agreement with respect to, or to hold any Company Indemnified Person harmless from, any claim or group of related claims, unless such
claim or group of related claims involves Losses in excess of $10,000 (all such claims or group of related claims of an amount equal to $10,000 or less, a “De Minimis Claim”), nor shall any De Minimis Claim be applied to or
considered for purposes of calculating the aggregate amount of the Parent Indemnified Persons’ or Company Indemnified Persons’ Losses, as applicable; provided that the limitations provided in this sentence shall only apply with respect to
an aggregate of up to $100,000 of De Minimis Claims and if all De Minimis Claims in the aggregate exceed $100,000 (such excess, “Excess De Minimis Claims”), the Members and Parent shall, as applicable, subject to the other
limitations provided in this Agreement, indemnify and hold the Parent Indemnified Persons or Company Indemnified Persons, as applicable, harmless from the amount of such excess over $100,000 and the amount of such excess shall be applied to and
considered for purposes of calculating the aggregate amount of the Parent Indemnified Persons’ or Company Indemnified Persons’ Losses, as applicable, needed to meet the Deductible and the Liability Cap. In addition, the Members shall not
be liable for the indemnification obligations pursuant to Section 9.1.1, Section 9.1.4, Section 9.1.5 or Section 9.1.6, or to hold the Parent Indemnified Persons harmless, and Parent shall not be liable for
the indemnification obligations pursuant to Section 9.2.1, or to hold the Company Indemnified Persons harmless, until the aggregate amount of Losses, including Losses with respect to Excess De Minimis Claims, with respect to matters
referred to, in the case of the Members, Section 9.1.1, Section 9.1.4, Section 9.1.5 and Section 9.1.6 or, in the case of the Parent, Section 9.2.1 exceeds $600,000 excluding in calculating
such amount any De Minimis Claims but not Excess De Minimis Claims (the “Deductible”), after which Parent, on the one hand, and the Members jointly and severally, on the other hand, will be responsible for all Losses, including
Losses with respect to Excess De Minimis Claims, in excess of the Deductible up to a maximum aggregate amount of Losses equal to Thirteen Million Six Hundred and Fifty Dollars ($13,650,000) (the “Liability Cap”). Notwithstanding
anything herein to the contrary, (A) none of the De Minimis Claim limitation, the Deductible or the Liability Cap will apply (i) in the case of fraud, intentional misrepresentation or willful misconduct or (ii) with respect to
Members’ indemnification obligations pursuant to Section 9.1.2, (B) the Deductible or the Liability Cap will not apply with respect to the Members’ indemnification obligations pursuant to Section 9.1.7, and
(C) the Liability Cap will not apply (i) with respect to any breach of Sections 2.1 (Organization; Predecessors; Subsidiaries), 2.2 (Capitalization of the Companies), 2.3 (Organization; Power and
Authorization), 2.5 (Noncontravention), the penultimate sentence of 2.6.1 (Financial Statements), 2.9.1 (Ownership of Assets), 2.17 (Employee Benefit Plans), 2.18 (Environmental Matters), the last sentence of
2.25.6 (Employees), 2.30 (No Brokers), 3.1 (Organization), 3.2 (Power and Authorization), 3.4 (Noncontravention) or 3.5 (No Brokers), or (ii) with respect to Members’ indemnification obligations

(ii) Strauss and Campbell shall have no liability for any claim that may be made or suit instituted seeking indemnification pursuant to Section 9.1.3 except to the extent that such claim relates to a breach or a violation of a
covenant or agreement of such Member and then solely with respect to such Member’s breach or violation. 
 9.5 Third
Party Claims. 
 9.5.1 Notice of Claim. If any third party notifies an Indemnified Person with respect to any matter
(a “Third Party Claim”) which may give rise to an Indemnity Claim against an Indemnifying Person under this Section 9, then the Indemnified Person will promptly give written notice to the Indemnifying Person;
provided, however, that no delay on the part of the Indemnified Person in notifying the Indemnifying Person will relieve the Indemnifying Person from any obligation under this Section 9 except to the extent that the
Indemnifying Person is actually prejudiced by the Indemnified Party’s failure to give such notice in such a timely manner. 

9.5.2 Assumption of Defense, etc. The Indemnifying Person will be entitled to participate in the defense of any Third Party Claim
that is the subject of a notice given by the Indemnified Person pursuant to Section 9.5.1. In addition, the Indemnifying Person will have the right to assume the defense of the Indemnified Person against the Third Party Claim with
counsel with counsel reasonably satisfactory (taking into account the jurisdiction in which the claim is brought, the materiality of the claim and the experience levels and other qualifications of counsel available to defend such claim) to the
Indemnified Person so long as (a) the Indemnifying Person 

 
gives written notice to the Indemnified Person within ten (10) days after the Indemnified Person has given notice of the Third Party Claim that the Indemnifying Person will indemnify the
Indemnified Person from and against the entirety of any and all Losses the Indemnified Person may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim, (b) the Indemnifying Person provides the
Indemnified Person with evidence reasonably acceptable to the Indemnified Person that the Indemnifying Person will have adequate financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder,
(c) the Third Party Claim involves only money damages and does not seek an injunction or other equitable relief against the Indemnified Person, (d) the Indemnified Person has not been advised by counsel that an actual or potential conflict
exists between the Indemnified Person and the Indemnifying Person in connection with the defense of the Third Party Claim, (e) the Third Party Claim does not relate to or otherwise arise in connection with Taxes or any criminal or regulatory
enforcement Action and (f) the Indemnifying Person conducts the defense of the Third Party Claim actively and diligently. The Indemnified Person may retain separate co-counsel at its sole cost and expense and participate in the defense of the
Third Party Claim; provided, however, that the Indemnifying Person will pay the fees and expenses of separate co-counsel retained by the Indemnified Person that are incurred prior to the Indemnifying Person’s assumption of control
of the defense of the Third Party Claim. 
 9.5.3 Limitations on Indemnifying Person. The Indemnifying Person will not
consent to the entry of any judgment or enter into any compromise or settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Person, which consent will not be unreasonably withheld, conditioned or
delayed, unless such judgment, compromise or settlement (a) provides for the payment by the Indemnifying Person of money as sole relief for the claimant, (b) results in the full and general release of all Parent Indemnified Persons or
Company Indemnified Persons, as applicable, from all Liabilities arising or relating to, or in connection with, the Third Party Claim and (c) involves no finding or admission of any violation of Legal Requirements or the rights of any Person
and has no effect on any other claims that may be made against the Indemnified Person. 
 9.5.4 Indemnified Person’s
Control. If the Indemnifying Person does not deliver the notice contemplated by clause (a), or the evidence contemplated by clause (b), of Section 9.5.2 within 10 (ten) days after the Indemnified Person has given notice of the Third
Party Claim, or otherwise at any time fails to conduct the defense of the Third Party Claim actively and diligently, the Indemnified Person may defend, and may consent to the entry of any judgment or enter into any compromise or settlement with
respect to, the Third Party Claim with the consent of the Indemnifying Person, which consent shall not be unreasonably delayed, conditioned or withheld. If such notice and evidence is given on a timely basis and the Indemnifying Person conducts the
defense of the Third Party Claim actively and diligently but any of the other conditions in Section 9.5.2 is or becomes unsatisfied, the Indemnified Person may defend, and may consent to the entry of any judgment or enter into any
compromise or settlement with respect to, the Third Party Claim with the consent of the Indemnifying Person, which consent shall not be unreasonably delayed, conditioned or withheld. In the event that the Indemnified Person conducts the defense of
the Third Party Claim pursuant to this Section 9.5.4, the Indemnifying Person will (a) advance the Indemnified Person promptly and periodically for the costs of defending against the Third Party Claim (including reasonable
attorneys’ fees and expenses) and (b) remain responsible for any and all other Losses that the Indemnified Person may incur or suffer resulting from, arising out of, relating to, in the nature of or caused by the Third Party Claim to the
fullest extent provided in this Section 9. 
 9.5.5 Reasonable Cooperation. The party not in control of the
prosecution or defense of a Third Party Claim will reasonably cooperate with the other party in the conduct of the prosecution or defense of such Third Party Claim. 
 9.6 Limitations on Liability. If a breach of the representations, warranties or covenants given by the Members in this Agreement is capable of remedy without Loss to Parent or the Parent
Indemnified Persons, the Parent Indemnified Persons shall only be entitled to indemnification if the breach is not remedied within thirty (30) days after the date on which notice is served on the Members’ Representative. 

9.7 Exclusive Remedy. Parent acknowledges and agrees that, should the Closing occur, except with respect to claims based on fraud,
intentional misrepresentation or willful misconduct, Parent Indemnified Persons’ sole and exclusive remedy with respect to any and all claims relating to this Agreement, whether based on contract, tort, strict liability, other laws or
otherwise, including any breach or alleged breach of any representation, warranty, covenant or agreement shall be pursuant to the indemnification provisions set forth in this Section 9 and Section 10 and the provisions set
forth in Section 5.2.3 and Section 11.18, and hereby waives, for itself and on behalf of the Parent Indemnified Persons, from and after the Closing, to the fullest extent permitted under applicable Law, any and all other
rights, claims and causes of action (other than rights, claims, or causes of action arising from fraud, intentional misrepresentation or willful misconduct) it may have against Members arising under or based upon any Law or otherwise relating to
this Agreement. The Members acknowledge and agree that, should the Closing occur, except with respect to claims based on fraud, intentional misrepresentation or willful misconduct, Company Indemnified Persons’ sole and exclusive remedy with
respect to any and all claims relating to this Agreement, whether based on contract, tort, strict liability, other laws or otherwise, including any breach or alleged breach of any representation, warranty, covenant or agreement shall be pursuant to
the indemnification provisions set forth in this Section 9, and hereby waive, for itself or himself and on behalf of the Company Indemnified Persons, from and after the Closing, to the fullest extent permitted under applicable Law, any
and all other rights, claims and causes of action (other than rights, claims, or causes of action arising from fraud, intentional misrepresentation or willful misconduct) it or he may have against Parent arising under or based upon any Law or
otherwise relating to this Agreement. 

 9.8 Members’ Representative. For purposes of this Section 9, it is
understood and agreed that the Members’ Representative shall act on behalf of all Members. 
 9.9 Knowledge and
Investigation. The right of any Parent Indemnified Person or Company Indemnified Person to indemnification pursuant to this Section 9 will not be affected by any investigation conducted or knowledge acquired (or capable of being
acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to the accuracy of any representation or warranty, performance of or compliance with any covenant or agreement, referred to in
Sections 9.1 or 9.2, or otherwise. 
 9.10 Remedies Cumulative. The rights of each Parent Indemnified
Person and Company Indemnified Person under this Section 9 are cumulative, and each Parent Indemnified Person and Company Indemnified Person, as the case may be, will have the right in any particular circumstance, in its sole discretion,
to enforce any provision of this Section 9 without regard to the availability of a remedy under any other provision of this Section 9. 
 9.11 Right of Setoff. Upon notice to the Members specifying in reasonable detail the basis therefore, Parent may set off any amount to which it may be entitled from the Members against amounts
otherwise payable, if any, under this Agreement. If such setoff is made against Parent Shares, such shares shall be valued on the day immediately prior to the day such shares were due to be issued, absent the setoff. The exercise of such right of
setoff by Parent in good faith, whether or not ultimately determined to be justified, will not constitute an event of default under this Agreement or any other agreement between Parent or any of its Affiliates and the Companies or Members. Neither
the exercise or failure to exercise such right of setoff will constitute an election of remedies or limit Parent in any manner in the enforcement of any other remedies that may be available to it. Notwithstanding the foregoing, if Parent sets off an
amount pursuant to this Section 9.11 and it is later finally mutually determined by the parties or pursuant to Section 11.15 that such setoff amount was in excess of the amount which any Member was required to indemnify
Parent, then Parent shall pay interest to such Member on such excess amount at the Prime Rate as published in the Wall Street Journal on the date such setoff was made. 
 9.12 ECS’s Indemnification Obligations. The obligation of ECS to indemnify Parent and the other Parent Indemnified Persons shall terminate in all respects upon the Closing; provided that for
the avoidance of doubt the parties agree that the termination of ECS’s indemnification obligations pursuant to this Section 9.12 shall have no effect on or in any way limit Parent’s or any other Parent Indemnified Person’s
rights to indemnification from the Members, including Parent’s and the other Parent Indemnified Persons’ rights to offset Losses that are incurred by or imposed on Parent or any other Parent Indemnified Person against any amounts otherwise
payable pursuant to this Agreement. In addition, the Members’ rights to seek contribution or payment of any amount from any Company for any indemnification obligations that they are required to make to Parent or any other Parent Indemnified
Person shall also terminate in all respects upon the Closing. If any Company suffers, incurs or otherwise becomes subject to any Losses as a result of or in connection with any inaccuracy in or breach of any representation, warranty, covenant or
obligation of the Members hereunder, then (without limiting any of the rights of any Company, Parent or any other Parent Indemnified Persons as Indemnified Persons) Parent shall also be deemed, by virtue of its ownership of the Equity Securities of
the Companies, to have incurred Losses as a result of and in connection with such inaccuracy or breach but in any case the total amount both Parent and the Companies may recover shall not exceed the amount of Losses. 

9.13 Time of Payment of Claims. Except as otherwise set forth in this Section 9, any amount owing by any Person
pursuant to this Section 9 shall be paid within two (2) Business Days after determination of such amount. To the extent any ECS Member holds Parent Shares, such ECS Member may satisfy its indemnification obligations pursuant to
Section 9.1.1 or Section 10 by assignment of Parent Shares at an agreed value of $13 per share; provided, however, that if Parent issues Parent Shares in connection with any Earn-Out Payment then the
“agreed value” for purposes of valuing Parent Shares pursuant to this Section 9.13 shall be the volume weighted average price of all Parent Shares issued to such ECS Member. 

9.14 Closing Balance Sheet. Notwithstanding anything to the contrary set forth in this Agreement, no Parent Indemnified Person
shall be entitled to indemnification pursuant to Section 9.1.1 or Section 10 for any Loss or Taxes or alleged Loss or Taxes to the extent of any Liability, accrual or reserve therefor is included as a current Liability in the
Actual Closing Balance Sheet.

Indemnified Taxpayer is entitled to an indemnification payment for a Loss pursuant to Section 10.2.1, the Members thereupon shall jointly and severally pay to the Indemnified Taxpayer an amount that, net of any Taxes imposed on the
Indemnified Taxpayer with respect to the payment, will indemnify and hold the Indemnified Taxpayer harmless from the Loss. 
 10.2.3 Notwithstanding anything to the contrary in this Agreement, the indemnification obligations of the Members under this Section 10 shall survive the Closing until the 90th day following the end of the applicable statutes of limitations.

 10.2.4 All transfer, documentary, sales, use, stamp, registration and other similar Taxes and fees (including any penalties
and interest) incurred in connection with this Agreement shall be jointly and severally paid by Members when due, and Members will, at their expense, file all necessary Tax Returns and other documentation with respect to all the transfer,
documentary, sales, use, stamp, registration and other Taxes and fees, and, if required by applicable Law, Parent will, and will cause its Affiliates to, join in the execution of any of those Tax Returns and other documentation. 

10.3 Covenants With Respect To Taxes. 
 10.3.1 Parent shall (i) grant to the Members’ Representative reasonable access to the Companies’ books and records (including tax workpapers and returns and correspondence with tax
authorities), including the right to take extracts therefrom and make copies thereof, to the extent that the books and records relate to the operations of the Companies during taxable periods ending on or prior to or that include the Closing Date as
may be necessary for Tax Return preparation, audit, or other financial reporting matters, and (ii) otherwise reasonably cooperate with the Members’ Representative in connection with the preparation and filing of any Tax Return of the
Company that the Members are responsible for and with any audit of Taxes that relates to the Businesses of the Companies prior to the Closing Date, in each case to the extent relevant to the Members’ indemnification obligations under
Section 10.2. 
 10.3.2 Parent shall be responsible for preparing and filing, or causing the Companies to prepare
and file, all Tax Returns of the Companies required to be filed for taxable periods ending after the Closing Date and the Members shall be responsible, at their cost, for filing all Tax Returns of the Companies for taxable periods ending on or
before the Closing Date (“Member-Prepared Returns”). The Member shall furnish such Member-Prepared Returns to the Parent for its review, comment and approval (such approval not to be unreasonably withheld, conditioned or delayed) at
least 30 days prior to the due date (or extended due date) for filing such Tax Returns, and such Tax Returns shall be prepared in accordance with past practice, except as required by Law. The Members shall pay all Taxes required to be paid with
respect to Member-Prepared Returns, except to the extent such Taxes have been previously paid, deposited 

 
or accrued in Actual Net Working Capital on the Actual Closing Balance Sheet. In the case of any Tax Returns other than income Tax Returns (a “Straddle Return”) for taxable
periods which begin before the Closing Date and end after the Closing Date (a “Straddle Period”), Parent shall furnish such Tax Returns to the Member’s Representative for its review, comment and approval (such approval not to
be unreasonably withheld, conditioned or delayed) at least 30 days prior to the due date (or extended due date) for filing such Tax Returns, and such Tax Returns shall be prepared in accordance with past practice, except as required by Law. The
Members shall jointly and severally pay to Parent within five (5) days after the date on which Taxes are paid with respect to a Straddle Return approved by the Members’ Representative (or as to which the refusal of Members’
Representative to approve is unreasonable) an amount equal to the portion of those Taxes that relates to the portion of the taxable period ending on the Closing Date as determined pursuant to Section 10.3.3, reduced to the extent such
Taxes have been previously paid, deposited or accrued in Actual Net Working Capital on the Actual Closing Balance Sheet. 

10.3.3 For purposes of this Agreement, other than in the case of income Tax Returns, in the case of any period that begins before the
Closing Date and ends after the Closing Date, any Tax based directly or indirectly on gross or net income or receipts or imposed in respect of specific transactions and any credits available with respect to any Tax, shall be allocated based on an
interim closing of the books by assuming that the taxable period ended on the Closing Date, and any other Tax shall be allocated based on the number of days in the taxable period ending on the Closing Date divided by the total number of days in the
taxable period. 
 10.3.4 Neither Parent nor its Affiliates (including the Companies) may amend or cause the amendment of a Tax
Return of the Companies, or file or amend any Tax election concerning the Companies, with respect to any period ending on or prior to the Closing Date or any period that begins before and ends after the Closing Date, if such action could have the
effect of increasing the Tax liability or reducing any Tax benefit of the Sellers or any Affiliate of the Sellers, without the written consent of the Members’ Representative, which consent shall not be unreasonably withheld, conditioned or
delayed, except if such amendment is required by any Governmental Authority. 
 10.3.5 Except to the extent reflected as an
asset in the Actual Closing Balance Sheet or to the extent resulting from the carryback of a net operating loss or other Tax attribute from a taxable period (or portion thereof) that begins on or after the Closing Date, any refund of Taxes of the
Companies (including any interest with respect thereto) attributable to any period occurring on or before the Closing Date, or as allocated pursuant to Section 10.3.3, shall be the property of the Members, shall be paid promptly to the
Members’ Representative and, if received by Parent or its Affiliate (including the Companies), shall be payable promptly to the Members’ Representative. 
 10.3.6 Parent shall not permit, and shall cause its Affiliates not to permit, the Companies to take any actions on the Closing Date that are out of the ordinary course of business of either Company,
except as required or contemplated by this Agreement.

 Each of the parties to this Agreement
may specify a different address or facsimile number by giving notice in accordance with this Section 11.1 to each of the other parties hereto. 
 11.2 Members’ Representative. 
 11.2.1 Appointment.
“Members’ Representative” means Force Capital provided that either Martin Maslonka or Casey Maslonka, or any of their Affiliates, is the beneficial owner of all of the Equity Securities thereof and materially participates in
the management of such entity. The Members hereby irrevocably constitute and appoint the Members’ Representative as their attorney-in-fact and agent to act in their names, place and stead in connection with all matters arising from and under
this Agreement, each of the Company Agreements and any other agreements, documents or instruments related to the Contemplated Transactions and acknowledge that such appointment is coupled with an interest. Members’ Representative hereby accepts
such appointment and authorization. 
 11.2.2 Authority. The Members agree to be bound by all notices received or given
by, and all agreements and determinations made by, and all documents executed and delivered by the Members’ Representative under this Agreement; authorize the Members’ Representative to assert claims, make demands and commence actions on
behalf of the Members under this Agreement, dispute or to refrain from disputing any claim made by the Members, negotiate and compromise any dispute that may arise under, and exercise or refrain from exercising remedies available to the Members
under, this Agreement, and to sign any releases or other documents with respect to such dispute or remedy (and to bind the Members in so doing), give such instructions and do such other things and refrain from doing such things as the Members’
Representative shall deem appropriate to carry out the provisions of this Agreement, give any and all consents and notices under this Agreement, and perform all actions, exercise all powers, receive service of process with respect to any Action
under this Agreement, any Company Agreement and any other agreement or instrument in connection with the Contemplated Transactions, agree to, negotiate and authorize payments in connection with the Purchase Price Adjustment and any other payment
pursuant to the terms of this Agreement, and fulfill all duties otherwise assigned to the Members’ Representative in this Agreement. Each Member hereby expressly acknowledges and agrees that the Members’ Representative has the sole and
exclusive authority to act on the Members’ behalf in respect of all matters arising under or in connection with this Agreement after execution of this Agreement, notwithstanding any dispute or

 
disagreement among them, and that no Member shall have any authority to act unilaterally or independently of the Members’ Representative in respect to any such matter. Parent shall be
entitled to rely on any and all actions taken by the Members’ Representative under this Agreement without any Liability to, or obligation to inquire of, the Members. All notices, counter notices or other instruments or designations delivered by
the Members in regard to this Agreement shall not be effective unless, but shall be effective if, signed by the Members’ Representative, and if not, such document shall have no force or effect whatsoever, and Parent and any other Person may
proceed without regard to any such document. 
 11.2.3 Change of Representative. The Members’ Representative may be
changed by the Members upon not less than twenty (20) calendar days prior written notice to Parent; provided, that the Members’ Representative may not be removed unless ECS Members holding a majority of the Common Units agree to such
removal and to the identity of the substituted agent or agents. The Members’ Representative may resign at any time upon not less than thirty (30) calendar days’ prior written notice to Parent, but in any event, not prior to the
appointment of a substitute Members’ Representative. No bond shall be required of the Members’ Representative. Notices or communications to or from the Members’ Representative shall constitute notice to or from the Members.

 11.2.4 A decision, act, consent or instruction of the Members’ Representative, including an amendment, extension or
waiver of this Agreement, shall constitute a decision of the Members and shall be final, binding and conclusive upon the Members; and Parent may conclusively and absolutely, rely, without any inquiry, upon any such decision, act, consent or
instruction of the Members’ Representative as being the decision, act, consent or instruction of the Members. Parent is hereby relieved from any Liability to any Person, including the Members, for any acts done by it in accordance with or
reliance on such decision, act, consent or instruction of the Members’ Representative. 
 11.2.5 All notices or other
communications required to be made or delivered by Parent to the Members shall be made to the Members’ Representative for the benefit of the Members, and any notices so made shall discharge in full all notice requirements of Parent to the
Members with respect thereto. All notices or other communications required to be made or delivered by the Members to Parent shall be made by the Members’ Representative for the benefit of the Members and any notices so made shall discharge in
full all notice requirements of the Members to Parent with respect thereto. 
 11.3 Publicity. No public announcement or
disclosure will be made by any party with respect to the subject matter of this Agreement or the Contemplated Transactions without the prior written consent of Parent and the Member’s Representative; provided, however, that the
provisions of this Section 11.3 will not prohibit (a) any disclosure required by any applicable Legal Requirements, including any disclosure necessary or desirable to provide proper disclosure under the securities laws or under any
rules or regulations of any securities exchange on which the securities of such party may be listed or traded or (b) any disclosure made in connection with the enforcement of any right or remedy relating to, or the performance of any obligation
arising under, this Agreement or the Contemplated Transactions. 
 11.4 Succession and Assignment; No Third-Party
Beneficiary. Subject to the immediately following sentence, this Agreement will be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, each of such successors and permitted assigns
will be deemed to be a party hereto for all purposes hereof. No party may assign, delegate or otherwise transfer either this Agreement or any of its rights, interests, or obligations hereunder (other than transfers by operation of law) without the
prior written approval of the other parties; provided, however, that Parent may (a) assign any or all of its rights and interests hereunder to one or more of its Affiliates and (b) designate one or more of its Affiliates to
perform its obligations hereunder, provided that any such assignment or designation shall in no event limit, reduce or release Parent’s obligations hereunder. Except as expressly set forth in Section 9 with respect to Indemnified
Persons who are not parties to this Agreement, this Agreement is for the sole benefit of the parties hereto and their permitted successors and assignees and nothing herein expressed or implied will give or be construed to give any Person, other than
the parties and such successors and assignees, any legal or equitable rights hereunder. 
 11.5 Amendments and Waivers.
No amendment or waiver of any provision of this Agreement will be valid and binding unless it is in writing and signed, in the case of an amendment, by the Parent and the Members’ Representative, or in the case of a waiver, by the party or
parties against whom the waiver is to be effective. No waiver by any party of any breach or violation or, default under or inaccuracy in any representation, warranty or covenant hereunder, whether intentional or not, will be deemed to extend to any
prior or subsequent breach, violation, default of, or inaccuracy in, any such representation, warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. No delay or omission on the
part of any party in exercising any right, power or remedy under this Agreement will operate as a waiver thereof. 
 11.6
Further Assurances. From and after the date hereof, upon the request of the Members’ Representative or Parent, each party will do, execute, acknowledge and deliver all such further acts, assurances, deeds, assignments, transfers,
conveyances and other instruments and papers as may be reasonably required or appropriate to carry out the Contemplated Transactions. 
 11.7 Entire Agreement. This Agreement, the Company Agreements and the other agreements and documents to be executed and delivered pursuant hereto constitute the entire agreement among the parties
hereto with respect to the subject matter hereof and supersede any and all prior and contemporaneous discussions, negotiations, proposals, undertakings, understandings and agreements, 

 
whether written or oral, with respect thereto. Notwithstanding the foregoing, some or all of the Members may currently or in the future be party to other restrictive covenant agreements with the
Companies, Parent, or others, and nothing in this Agreement is intended to supersede or otherwise affect any such other restrictive covenant agreement. 
 11.8 Disclosure Schedules; Listed Documents, etc. Neither the listing nor description of any item, matter or document in any Schedule hereto nor the furnishing or availability for review of any
document will be construed to modify, qualify or disclose an exception to any representation or warranty of any party made herein or in connection herewith, except to the extent that (a) such representation or warranty specifically refers to
the disclosures in such section of the Disclosure Schedule and (b) to the extent disclosed in another section of the Disclosure Schedules, to the extent that it is reasonably apparent from a reading of the disclosure that such disclosure would
also qualify or apply to such other section. The inclusion of any information in any Disclosure Schedule shall not be deemed to be an admission or evidence of the materiality of such item. In addition, matters reflected in the Disclosure Schedules
are not necessarily limited to matters required by this Agreement to be reflected in the Disclosure Schedules. Such additional matters are set forth for informational purposes only and do not necessarily include other matters of a similar nature.
The information contained in this Agreement, in the Disclosure Schedules, and exhibits hereto is disclosed solely for purposes of this Agreement, and no information contained herein or therein shall be deemed to be an admission by any party hereto
to any Person other than the parties hereto of any matter whatsoever (including any violation of Law or breach of contract). 

11.9 Counterparts; Execution. This Agreement may be executed in any number of counterparts, each of which will be deemed an
original, but all of which together will constitute but one and the same instrument. This Agreement will become effective when duly executed by each party hereto. Facsimile or other electronically scanned and transmitted signatures shall be deemed
originals and shall constitute valid execution and acceptance of this Agreement by the signing/transmitting party. 
 11.10
Survival. The covenants and agreements and, subject to Section 9.3, the representations and warranties set forth in this Agreement shall survive and remain in effect after the Closing. 

11.11 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction
will not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If any provision hereof would,
under applicable Law, be invalid or unenforceable in any respect, then each party hereto intends that such provision will be construed by modifying or limiting it so as to be valid and enforceable to the maximum extent compatible with, and possible
under, applicable Law. 
 11.12 Headings. The headings contained in this Agreement are for convenience purposes only and
will not in any way affect the meaning or interpretation hereof. 
 11.13 Construction. The parties have participated
jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will
arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement. The parties intend that each representation, warranty and covenant contained herein will have independent significance. If any party has
breached or violated, or if there is an inaccuracy in, any representation, warranty or covenant contained herein, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative
levels of specificity) which the party has not breached or violated, or in respect of which there is not an inaccuracy, will not detract from or mitigate the fact that the party has breached or violated, or there is an inaccuracy in, the first
representation, warranty or covenant. 
 11.14 Governing Law. This Agreement, the rights of the parties and all Actions
arising in whole or in part under or in connection herewith, will be governed by and construed in accordance with the laws of the State of Florida, without giving effect to any choice or conflict of law provision or rule that would cause the
application of the laws of any other jurisdiction. 
 11.15 Jurisdiction; Venue; Service of Process. 

11.15.1 Jurisdiction. Each party, by its execution hereof, (a) hereby irrevocably submits to the exclusive jurisdiction of
the state courts of the State of Florida or the United States District Courts located in the Southern District of Florida for the purpose of any Action between or among the parties (or any of them), including but not limited to any such Action
arising or related in whole or in part under or in connection with this Agreement, (b) hereby waives to the extent not prohibited by applicable law, and agrees not to assert, by way of motion, as a defense or otherwise, in any such Action, any
claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that any such Action brought in one of the above-named courts should be dismissed on grounds
of forum non conveniens, should be transferred or removed to any court other than one of the above-named courts, or should be stayed by reason of the pendency of some other proceeding in any other court other than one of the above-named
courts, or that this Agreement or the subject matter hereof may not be enforced in or by such court and (c) hereby agrees not to commence any such Action other than before one of the above-named courts. Notwithstanding the previous sentence,
(x) a party may commence any Action in a court other than the above-named courts solely for the purpose of enforcing an order or judgment issued by one of the above-named courts, and (y) Parent may commence an Action in a court other than
the above-named courts in accordance with the provisions of Section 5.2.3. 

 11.15.2 Venue. With the exception of Actions brought by Parent in accordance with the
provisions of Section 5.2.3, each party agrees that for any Action between or among the parties (or any of them), including but not limited to any such Action arising or related in whole or in part under or in connection with this
Agreement, such party will bring Actions only in Miami-Dade County, Florida. Each party further waives any claim and will not assert that venue should properly lie in any other location within the selected jurisdiction. 

11.15.3 Service of Process. Each party hereby (a) consents to service of process in any Action between or among the parties
(or any of them) in any manner permitted by Florida law, (b) agrees that service of process made in accordance with clause (a) or made by registered or certified mail, return receipt requested, at its address specified pursuant to
Section 11.1, will constitute good and valid service of process in any such Action and (c) waives and agrees not to assert (by way of motion, as a defense, or otherwise) in any such Action any claim that service of process made in
accordance with clause (a) or (b) does not constitute good and valid service of process. 
 11.16 Waiver of Jury
Trial. THE PARTIES HEREBY WAIVE, AND COVENANT THAT THEY WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY ACTION BETWEEN OR AMONG THE PARTIES (OR ANY OF THEM), INCLUDING BUT NOT LIMITED TO ANY SUCH
ACTION ARISING OR RELATED IN WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE CONTEMPLATED TRANSACTIONS, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT
ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE THEIR RIGHTS TO TRIAL BY JURY IN ANY ACTION WHATSOEVER BETWEEN OR AMONG
THEM, WHICH ACTION WILL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY. 
 11.17
Expenses. Except as provided in Sections 1.11.3, 9 or 10, (i) ECS shall pay all of ECS’s and the Members’ fees and expenses, including legal and accounting fees and expenses and the brokers fees and
expenses disclosed on Schedules 2.30(a) and 2.30(b), incurred in connection with this Agreement and the Contemplated Transactions; provided however, that any such fees and expenses that have not been paid on or before the Closing Date
and are not reflected as a Liability in the Actual Closing Balance Sheet shall be paid by the Members, and (ii) the Parent shall pay all of its own fees and expenses incurred in connection with this Agreement and the Contemplated Transactions.

 11.18 Specific Performance. Parent shall have the right and remedy, in addition to any others that may be available,
at law or in equity, to have the provisions of this Agreement, and each Company Agreement, specifically enforced through injunctive or other relief, without the necessity of posting a bond, it being acknowledged that each Company is a unique asset,
with value to Parent’s business not readily quantifiable and any breach by ECS or Members of the provisions of this Agreement or the Company Agreements will cause irreparable injury to Parent, the amount of which will be difficult to determine,
and that money damages will not provide an adequate remedy to Parent. ECS and Members covenant and agree that they shall not, and shall not authorize any other Person to, challenge or question the enforceability of any provision of this
Section 11.18. 
 11.19 Joint and Several. Except as set forth in Section 9.4.2, the covenants,
agreements, obligations and Liabilities of ECS and Members hereunder and under each Company Agreement, shall be joint and several in all respects. Where in this Agreement or any agreement or document referred to in the preceding sentence, provision
is made for any action to be taken or not to be taken by any Company or Members, ECS and Members agree to cause such Persons to take or not to take such action and shall be jointly and severally Liable for such Persons taking or not taking any such
action, as the case may be. 
 11.20 Recitals. The recitals to this Agreement are true and correct and by this reference
are incorporated herein and made a part of this Agreement. 
 11.21 Representation by Lewis and Roca LLP. Parent hereby
acknowledges that Lewis and Roca LLP has served as legal counsel to ECS, Force Capital, FCP Investments, Martin Maslonka, and certain of their Affiliates in connection with this Agreement and the Contemplated Transactions and on other matters prior
to the parties commencing discussions regarding the Contemplated Transactions. Parent and ECS acknowledge and agree that Lewis and Roca LLP may continue to serve as legal counsel for Force Capital, FCP Investments and Martin Maslonka from and after
the Closing with respect to the Contemplated Transactions.
